Technical Field

This disclosure relates to the field of air conditioning technology, and in particular to a top-discharge outdoor unit for an air conditioner.

Background Technology

Based on the location of the air outlet, air conditioner outdoor units are generally divided into top-discharge air conditioner outdoor units and side-discharge air conditioner outdoor units. In top-discharge air conditioner outdoor units, the air outlet is located at the top of the casing, while in side-discharge air conditioner outdoor units, the air outlet is located on the outer perimeter of the casing.

In a top-discharge air conditioner outdoor unit, the casing typically includes components such as a top cover, side panels, and a chassis. The top cover and chassis are located at the top and bottom of the side panels, respectively. The top cover, side panels, and chassis together define a receiving cavity, in which components such as the compressor, outdoor heat exchanger, and heat exchange fan are located.

Summary of the Invention

This disclosure aims to solve the connection problem between the side panel, top cover, and chassis of the outdoor unit of an air conditioner.

This disclosure provides some embodiments of a top-discharge air conditioning outdoor unit, including a casing, a heat exchange fan, an outdoor heat exchanger, and a compressor. The casing includes an air inlet and an air outlet, with the air inlet located on the outer periphery of the casing and the air outlet located on the top of the casing. An internal cavity is defined within the casing, and the air inlet and air outlet communicate with the cavity. The heat exchange fan is disposed within the cavity, near the air outlet. The outdoor heat exchanger is disposed within the cavity, near the air inlet. The compressor is disposed within the cavity. The casing includes a top cover, side panels, a chassis, a first bend, a second bend, and a positioning protrusion. The top cover is located on the top of the outdoor unit, and the air outlet is located on the top cover. The side panels are located on the outer periphery of the outdoor unit, and the air inlet is located on the side panels. The chassis is located at the bottom of the outdoor unit. The outdoor heat exchanger and compressor are placed on the chassis; the chassis and top cover are correspondingly arranged along the height direction of the casing; the chassis, side plates and top cover together define a receiving cavity; a first bent portion is provided on the outer edge of the top cover, and the first bent portion is provided on the side plate away from the receiving cavity, the first bent portion and the side plate away from the receiving cavity are correspondingly arranged in the horizontal direction and there is a gap between them; a second bent portion is provided on the outer edge of the chassis, and the second bent portion and the side plate away from the receiving cavity are correspondingly arranged in the horizontal direction and there is a gap between them; a positioning protrusion is provided on the surface of the side plate away from the receiving cavity, and the positioning protrusion contacts and connects with the side of the first bent portion facing the side plate and the side of the second bent portion facing the side plate.

This technical solution involves setting a positioning protrusion on the side of the side plate away from the receiving cavity. The positioning protrusion contacts the first bend and the second bend, so that the side plate makes "point contact" with the first bend and the second bend, thereby reducing the contact area between the side plate and the first bend and the second bend, and thus reducing the damage area of the side plate during transportation.

Detailed Implementation

The following description, in conjunction with the accompanying drawings, clearly and completely describes some embodiments of this disclosure. Obviously, the described embodiments are merely some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular "comprises" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," "specific example," or "some examples," etc., are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be included in any suitable manner in any one or more embodiments or examples.

Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

In describing some embodiments, the terms "coupled" and "connected," and their derivative expressions, may be used. The term "connected" should be interpreted broadly; for example, a "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. The term "coupled" indicates that two or more components have direct physical or electrical contact. The term "coupled" or "communicatively coupled" may also refer to two or more components that do not have direct contact with each other but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the content of this document.

"At least one of A, B and C" has the same meaning as "at least one of A, B or C", both including the following combinations of A, B and C: only A, only B, only C, combinations of A and B, combinations of A and C, combinations of B and C, and combinations of A, B and C.

"A and/or B" includes the following three combinations: A only, B only, and a combination of A and B.

The use of “applies to” or “configured to” in this article implies an open and inclusive language that does not preclude applicability to or configuration to devices that perform additional tasks or steps.

As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

As used herein, “parallel,” “perpendicular,” and “equal” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°; “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

In relevant air conditioner outdoor units, the side panels are mostly connected and fixed to the top cover and chassis using fasteners such as bolts or screws. The side panels are usually sheet metal, and their horizontal thickness is relatively thin. To prevent the side panels from being crushed due to stress concentration, the top of the side panel is usually a certain distance from the bottom of the top cover, so that the stress from the top cover on the side panel is concentrated on the fasteners used to connect the top cover and the side panel. The bottom of the side panel is also usually a certain distance from the chassis, so that the stress from the side panel on the chassis is concentrated on the fasteners used to connect the side panel and the chassis. This undoubtedly reduces the fatigue life of the fasteners and may even cause them to break, thereby reducing the reliability of the connection between the top cover and the side panel, and between the side panel and the chassis. Moreover, for the convenience of connection, the outer edge of the top cover usually has a first bend, and the outer edge of the chassis usually has a second bend. The first bend and the second bend respectively contact the side of the side panel away from the receiving cavity and are connected to each other by fasteners. Since the side panel is in surface contact with the first and second bends, there may be friction between the side panel and the top and bottom panels during transportation, which may damage the paint on the side panel surface and accelerate the oxidation and corrosion of the side panel.

In related air conditioning outdoor units, the connection method between the side panel and the top cover and chassis is difficult to meet the requirements of top-discharge air conditioning outdoor units.

To address the aforementioned problems, as shown in Figure 1, the top-discharge outdoor unit of the air conditioner provided in this embodiment includes a housing 100, which forms the overall appearance of the outdoor unit. The top and bottom of the housing 100 are opposite ends, and the length from the bottom to the top of the housing 100 is its height direction. The left and right sides of the housing 100 are opposite sides, and the length from the left to the right side of the housing 100 is its length direction. The front and rear sides of the housing 100 are opposite sides, and the thickness from the front to the rear of the housing 100 is its thickness direction.

In practical applications, the outdoor unit of a top-discharge air conditioner is usually placed on the ground or on a support frame, and the bottom surface of the outdoor unit is usually in contact with the ground or support frame.

In some embodiments, as shown in FIG2, the housing 100 includes an air outlet 101. The air outlet 101 may be located at the top of the housing 100. Air inside the housing 100 may be discharged to the outside through the air outlet 101.

In some embodiments, the opening of the air outlet 101 is typically oriented upwards.

In some embodiments, as shown in Figures 2 and 5, the housing 100 includes an air inlet 102. The air inlet 102 may be located on the outer periphery of the housing 100. Air from outside the housing 100 may enter the interior of the housing 100 through the air inlet 102.

In some embodiments, the opening direction of the air inlet 102 intersects with the opening direction of the air outlet 101.

In some embodiments, as shown in Figures 2, 3 and 5, a receiving cavity 10 is defined inside the housing 100, and an air outlet 101 and an air inlet 102 are respectively connected to the receiving cavity 10.

In some embodiments, as shown in Figures 2 and 6, the housing 100 includes a top cover 110. The top cover 110 may be located on the top of the housing 100. An air outlet 101 may be formed in the top cover 110.

In some embodiments, as shown in FIG2, the housing 100 includes a side plate 120, which forms a side wall of the receiving cavity 10; the side plate 120 is located below the top cover 110 and is connected to the top cover 110, and an air inlet 102 is formed on the side plate 120.

In some embodiments, to facilitate the connection between the top cover 110 and the side panel 120, as shown in Figures 2 and 6, the top cover 110 is provided with a first bending portion 112. The first bending portion 112 may be provided on the outer edge of the top cover 110. The side of the first bending portion 112 away from the top cover 110 may be provided towards the bottom of the housing 100. The first bending portion 112 may be connected to the side panel 120.

When the top cover 110 is connected to the side plate 120, the first bent portion 112 can be located at the upper end of the side plate 120 and on the side of the side plate 120 away from the receiving cavity 10.

In some embodiments, the first bending portion 112 is provided with a first connecting hole, and the upper end of the side plate 120 is provided with a second connecting hole. The second connecting hole is provided in correspondence with the first connecting hole, and the same fastener is provided in the first connecting hole and the second connecting hole respectively, so that the top cover 110 and the side plate 120 are connected to each other.

In some embodiments, as shown in Figures 2 and 6, the first bent portion 112 can be formed by stretching the outer edge of the top cover 110, or the first bent portion 112 can be formed by bending the outer edge of the top cover 110.

In some embodiments, as shown in Figures 2 and 5, multiple air inlets 102 are provided, and the multiple air inlets 102 are distributed on the side plate 120.

In some embodiments, as shown in FIG12, the side plate 120 is connected to a guide portion 124. The guide portion 124 may be provided at the air inlet 102, and the guide portion 124 may be used to guide the air from the air inlet 102 into the receiving cavity 10.

In practical applications, the side panel 120 is usually a sheet metal part, and the surface of the side panel 120 is usually painted to prevent sheet metal oxidation.

In some embodiments, as shown in Figures 2 and 3, the housing 100 includes a chassis 130. The chassis 130 is disposed below the side panel 120. The chassis 130 and the top cover 110 may be correspondingly disposed along the height direction of the housing 100. The chassis 130 may be connected to the side panel 120. The chassis 130, the side panel 120, and the top cover 110 may together define a receiving cavity 10.

In some embodiments, as shown in Figures 1 and 11, the housing 100 is generally cuboid in shape. The chassis 130 may be chamfered quadrilateral.

In some embodiments, the chassis 130 is a sheet metal part, which gives the chassis 130 higher strength and can also reduce the production cost of the chassis 130.

In some embodiments, to facilitate the connection between the chassis 130 and the side plate 120, as shown in Figures 10 and 11, the chassis 130 is provided with a second bend 131. The second bend 131 is located on the outer edge of the chassis 130. The side of the second bend 131 away from the chassis 130 may be positioned towards the top of the housing 100. When the chassis 130 and the side plate 120 are connected, the second bend 131 is located at the lower end of the side plate 120 and on the side of the side plate 120 opposite to the receiving cavity 10.

In some embodiments, as shown in Figures 11 and 13, the second bend 131 is provided with a third connecting hole, and the lower end of the side plate 120 is provided with a fourth connecting hole. The fourth connecting hole can be provided correspondingly to the third connecting hole, and the same fastener is respectively provided in the third connecting hole and the fourth connecting hole, so that the chassis 130 and the side plate 120 are connected to each other.

In some embodiments, as shown in Figures 11 and 13, the second bent portion 131 may be formed by stretching the outer edge of the chassis 130, or the second bent portion 131 may be formed by bending the outer edge of the chassis 130.

In some embodiments, as shown in Figures 13 and 14, a first positioning portion 125 is provided at the lower end of the side plate 120. The first positioning portion 125 may be provided on the side of the side plate 120 away from the partition 320. The chassis 130 is provided with a second positioning portion 132, which may be provided in the second bend portion 131. The second positioning portion 132 may be located within the receiving cavity. The second positioning portion 132 and the first positioning portion 125 may be correspondingly provided and cooperate with each other to position the connection position between the chassis 130 and the side plate 120.

In some embodiments, as shown in Figures 13 and 14, the first positioning portion 125 is a notch, and the second positioning portion 132 is a protrusion of the second bent portion 131 toward the receiving cavity side.

When the side panel 120 is connected to the first bend 112 and the second bend 131, the side panel 120 and the first bend 112 and the second bend 131 respectively make “surface contact”. During the transportation of the top-discharge air conditioner outdoor unit, the side panel 120 and the first bend 112, and the side panel 120 and the second bend 131 are prone to relative movement, which damages the painted surface of the side panel 120 and accelerates the oxidation and corrosion of the side panel 120.

Based on this, in some embodiments, as shown in Figures 5, 15, and 16, a positioning protrusion 122 is provided on the side of the side plate 120 facing away from the receiving cavity. By making the positioning protrusion 122 contact the first bent portion 112 and the second bent portion 131, the side plate 120 and the first bent portion 112 and the second bent portion 131 respectively make "point contact," reducing the contact area between the side plate 120 and the first bent portion 112 and the second bent portion 131, thereby reducing damage to the side plate 120. In some embodiments, as shown in Figure 5, a positioning protrusion 122 is provided at the upper end of the side plate 120. The positioning protrusion 122 can be provided on the side of the side plate 120 facing away from the receiving cavity. The side plate 120 and the first bent portion 112 can have a gap in the horizontal direction. The positioning protrusion 122 at the upper end of the side plate 120 can be provided in the gap between the side plate 120 and the first bent portion 112. The positioning protrusion 122 at the upper end of the side plate 120 is in contact with the first bent part 112 and is connected to each other by fasteners.

In some embodiments, as shown in Figures 5 and 6, the horizontal gap between the side plate 120 and the first bent portion 112 is 1 mm. If the gap is too small, the side plate 120 and the first bent portion 112 are prone to collision. If the gap is too large, the side plate 120 and the first bent portion 112 are prone to wobbling.

In some embodiments, as shown in Figures 13 and 14, a positioning protrusion 122 is provided at the lower end of the side plate 120. The positioning protrusion 122 can be provided on the side of the side plate 120 away from the receiving cavity. The side plate 120 and the second bent portion 131 have a gap in the horizontal direction. The positioning protrusion 122 at the lower end of the side plate 120 can be provided in the gap between the side plate 120 and the first bent portion 112. The positioning protrusion 122 at the lower end of the side plate 120 can contact each other with the second bent portion 131 and be connected to each other by fasteners.

It should be noted that, in some embodiments, the second connecting hole may be provided on the positioning protrusion 122 at the upper end of the side plate 120. The fourth connecting hole may be provided on the positioning protrusion 122 at the lower end of the side plate 120.

In some embodiments, the positioning protrusion 122 can be formed by stamping the side plate 120 outwards, and the side plate 120 has a recess corresponding to the positioning protrusion 122 on its inner side. The positioning protrusion 122 can be manufactured by stamping, which can simplify the manufacturing process of the positioning protrusion 122 and improve production efficiency.

In some embodiments, as shown in FIG10, the horizontal gap between the side plate 120 and the second bend 131 is 1mm. If the gap is too small, the side plate 120 and the first bend 112 are prone to collision. If the gap is too large, the side plate 120 and the second bend 131 are prone to wobbling.

In some embodiments, as shown in FIG4, the top of the side plate 120 is provided with a first support portion 121. The first support portion 121 is in contact with the bottom surface of the top cover 110. The force exerted by the top cover 110 on the side plate 120 is transmitted to the side plate 120 through the first support portion 121, so that the side plate 120 supports the top cover 110, thereby preventing the fasteners connecting the side plate 120 and the top cover 110 from being subjected to shear force, thereby increasing the connection firmness between the side plate 120 and the top cover 110.

In some embodiments, as shown in FIG4, the first support portion 121 is formed by bending the top outer edge of the side plate 120. The top cover 110 is supported by the structure of the side plate 120 itself. This not only facilitates the production of the first support portion 121, but also reduces the number of parts of the outdoor unit of the air conditioner and facilitates assembly.

In some embodiments, as shown in FIG10, a second support portion 123 is provided at the bottom of the side plate 120. The second support portion 123 can contact the top surface of the chassis 130. The force exerted by the side plate 120 on the chassis 130 is transmitted to the chassis 130 through the second support portion 123, so that the chassis 130 supports the side plate 120, thereby preventing the fasteners connecting the side plate 120 and the chassis 130 from being subjected to shear force, and thus increasing the connection strength between the side plate 120 and the chassis 130.

In some embodiments, as shown in FIG10, the second support portion 123 is formed by bending the bottom outer edge of the side plate 120. The contact area between the side plate 120 and the chassis 130 is increased by utilizing the structure of the side plate 120 itself. This not only facilitates the production of the second support portion 123, but also reduces the number of components of the outdoor unit of the air conditioner, making assembly easier.

In some embodiments, as shown in Figures 1, 2, and 3, the top-discharge outdoor unit of an air conditioner includes an electrical control box 300. The electrical control box 300 may be located outside the receiving cavity 10. A mounting cavity may be defined within the electrical control box 300. Electrical components 330 required for the operation of the outdoor unit may be installed within the mounting cavity.

In some embodiments, as shown in FIG15, the electrical control box 300 includes an electrical control box cover 310. The electrical control box cover 310 may be located outside the receiving cavity. The electrical control box cover 310 may be horizontally disposed corresponding to at least a portion of the sidewall of the receiving cavity. The electrical control box cover 310 and the sidewall of the receiving cavity may together define a mounting cavity, in which the electrical control board and terminal blocks are respectively disposed.

In some embodiments, as shown in Figures 3 and 15, the control box cover 310 is located above the chassis 130. The control box cover 310 may be a certain distance from the chassis 130 along the height direction of the housing 100. The control box cover 310 may be positioned close to a chamfered corner of the chassis 130.

In some embodiments, as shown in FIG2, the control box cover 310 is connected to the top cover 110 by fasteners. On the one hand, the top cover 110 can constrain the control box cover 310, increasing the firmness of the connection of the control box 300; on the other hand, the top cover 110 can seal the top of the mounting cavity.

When the control box cover 310 is connected to the top cover 110, the first bending part 112 is provided on the outside of the control box cover 310 to increase the contact area between the top cover 110 and the control box cover 310, thereby increasing the connection effect between the top cover 110 and the control box cover 310.

It should be noted that, for ease of description, as shown in Figure 12, in this embodiment, the side wall of the receiving cavity corresponding to the electrical control box cover 310 is referred to as the partition 320. The partition 320 is used not only to form the side wall of the receiving cavity, but also to form the side wall of the mounting cavity, that is, the partition 320 is used to separate the receiving cavity and the mounting cavity.

In some embodiments, since the sidewalls of the receiving cavity are mostly formed by side plates 120, the partition 320 can be considered as part of the side plate 120; that is, the side plate 120 may include the partition 320, and the partition 320 is also a type of side plate 120. Alternatively, the partition 320 can be considered as a component independent of the side plate 120. It should be noted that in this embodiment, the partition 320 and the side plate 120 are considered as independent components.

In some embodiments, as shown in Figures 3 and 15, the partition 320 is interconnected with the side plate 120 and together defines the sidewall of the receiving cavity.

In some embodiments, as shown in Figures 3, 4 and 20, at the connection between the partition 320 and the side plate 120, the side of the partition 320 facing away from the interior of the housing 100 contacts the side of the side plate 120 facing the interior of the housing 100 to increase the contact area between the side plate 120 and the partition 320.

As shown in Figures 4 and 20, the partition 320 is provided with a limiting part 321. The limiting part 321 can extend along the height direction of the housing 100. The limiting part 321 can be set near the connection between the partition 320 and the side plate 120. The side of the side plate 120 extending along the height direction of the housing 100 contacts the limiting part 321 to position the connection between the side plate 120 and the partition 320.

In some embodiments, as shown in Figures 4 and 20, the limiting portion 321 has a protruding partition 320 disposed on the side opposite to the receiving cavity.

In other embodiments, the partition 320 is a sheet metal part. The limiting part 321 can be formed by stamping, and the side of the partition 320 facing the receiving cavity may have a recess that corresponds to the limiting part 321.

In other embodiments, the side of the control box cover 310 extending along the height direction of the housing 100 contacts the side of the limiting part 321 away from the side plate 120 to locate the connection position between the control box cover 310 and the partition 320.

In some embodiments, as shown in Figures 3 and 7, the side panel 120 has a notch, and the partition 320 may be located at the notch. The partition 320 may be connected to the side panel 120 on both sides along the height direction of the housing 100. The lower end of the partition 320 may be connected to the chassis 130. The partition 320, the side panel 120, the top cover 110, and the chassis 130 may together define a receiving cavity. The partition 320 and the electrical control box cover 310 may together define a mounting cavity.

In some embodiments, as shown in Figures 3 and 7, two side plates 120 are provided, and a notch extending along the height direction of the housing 100 may be defined between the two side plates 120. A partition 320 is provided at the notch, and the two sides of the partition 320 along the height direction of the housing 100 may be respectively connected to the two side plates 120.

In some embodiments, as shown in Figures 6, 11, and 15, the housing 100 further includes a column 140. The column 140 may be located at a corner of the chassis 130. The upper end of the column 140 may be connected to a first bend 112. The lower end of the column 140 may be connected to a second bend 131. The two sides of the column 140 along the height direction of the housing 100 are correspondingly connected to the sides of the two side plates 120 away from the partition 320. The column 140, the side plates 120, and the partition 320 together form the outer peripheral wall of the receiving cavity.

In some embodiments, as shown in Figures 7 and 15, the partition 320 is disposed near the chamfered corner of the chassis 130, and the column 140 may be disposed at the corner of the chassis 130 opposite to the chamfered corner.

In some embodiments, as shown in FIG14, the projections of the two side plates 120 in the horizontal plane are respectively L-shaped, so that the side plates 120 can extend along the outer edge of the chassis 130 and can be connected to the partition 320 and the column 140.

In some embodiments, as shown in Figures 2 and 15, two side plates 120 are provided, one column 140 is provided, and one partition 320 is provided. The housing 100 can be formed by connecting the two side plates 120, one column 140, one partition 320, one top cover 110 and one chassis 130 together with fasteners. The housing 100 contains fewer parts, has higher assembly efficiency, requires fewer fasteners for connection, and has lower production cost.

In some embodiments, as shown in Figures 6, 15, and 16, a positioning protrusion 122 is provided at the upper end of the column 140. A horizontal gap exists between the column 140 and the first bent portion 112. The positioning protrusion 122 at the upper end of the column 140 can contact the first bent portion 112 and be connected to it via fasteners.

In some embodiments, as shown in Figures 11, 15, and 16, a positioning protrusion 122 is provided at the lower end of the column 140. A horizontal gap exists between the column 140 and the second bend 131. The positioning protrusion 122 at the lower end of the column 140 can contact the second bend 131 and be connected to it via fasteners.

In some embodiments, as shown in Figures 11, 12, and 13, the side plate 120 is arranged symmetrically along the horizontal plane, so that the side plate 120 has a vertically symmetrical structure. The first support portion 121 and the second support portion 123 are arranged symmetrically along the horizontal plane. By arranging the side plate 120 and the first support portion 121 and the second support portion 123 symmetrically along the horizontal plane, the side plate 120 after the first support portion 121 and the second support portion 123 are provided is symmetrically arranged in the horizontal direction, thereby facilitating the assembly of the housing 100.

It should be noted that in some other embodiments, the side plates 120 may also be arranged asymmetrically along the horizontal plane. The first support portion 121 and the second support portion 123 may also be arranged asymmetrically along the horizontal plane.

In some embodiments, as shown in Figures 14, 15 and 16, the positioning protrusions 122 that are in contact with the first bending portion 112 are configured as seven positioning protrusions 122, which may be correspondingly located at the upper end of the side plate 120 and the upper end of the column 140.

In other embodiments, as shown in Figures 14, 15 and 16, the positioning protrusions 122 that are in contact with the second bending portion 131 are configured as seven positioning protrusions 122, which may be correspondingly located at the lower end of the side plate 120 and the lower end of the column 140.

In some embodiments, as shown in FIG2, the top-discharge air conditioner outdoor unit includes a heat exchange fan 400. The heat exchange fan 400 may be located inside a housing cavity. The heat exchange fan 400 may be positioned close to the air outlet 101. With the operation of the heat exchange fan 400, outdoor air enters the housing cavity through the air inlet 102 and is then discharged to the outside through the air outlet 101.

In some embodiments, in the outdoor unit of a top-discharge air conditioner, the heat exchange fan 400 is typically an axial flow fan. The heat exchange fan 400 and the air outlet 101 can be arranged correspondingly along the height direction of the casing 100.

In some embodiments, the heat exchange fan 400 includes fan blades for driving airflow.

In some embodiments, the heat exchange fan 400 includes a motor, with fan blades connected to the motor's output shaft. The motor may be located below the top cover 110. The motor's output shaft may be downward-facing. The motor is used to drive the fan blades to rotate.

In some embodiments, as shown in FIG1, the outdoor unit of a top-discharge air conditioner includes a fan shroud 200. The fan shroud 200 may be disposed at the air outlet 101 and connected to the top cover 110. The fan shroud 200 can be used to protect the heat exchange fan 400, protect the fan blades, and prevent damage to the fan or accidental injury caused by the intake of indoor debris. The fan shroud 200 can also concentrate and uniformly guide the airflow, making the airflow blown by the fan more concentrated and uniform.

In some embodiments, as shown in Figures 1 and 2, a motor is connected to a fan shroud 200 so that a heat exchange fan 400 is disposed within a receiving cavity.

In some embodiments, as shown in FIG6, the top cover 110 is connected to an air guide ring 111. The air guide ring 111 is located at the air outlet 101. The interior of the air guide ring 111 may define a cavity extending along the height direction of the housing 100, and at least part of the heat exchange fan 400 is located within the cavity. The air guide ring 111 can be used to guide the airflow within the cavity, allowing the heat exchange fan 400 to better perform its air-guiding function.

In some embodiments, as shown in Figures 3, 7, and 9, the outdoor unit of a top-discharge air conditioner includes an outdoor heat exchanger 500. The outdoor heat exchanger 500 is disposed within a receiving cavity and is used to exchange heat with air passing through it. The outdoor heat exchanger 500 may be positioned close to the air inlet 102. The outdoor heat exchanger 500 may be mounted on a chassis 130 so that the chassis 130 supports the outdoor heat exchanger 500.

In some embodiments, as shown in Figures 4, 8, and 10, the side plate 120 and the outdoor heat exchanger 500 have a horizontal gap on the side opposite to the receiving cavity. At least a portion of the first support portion 121 and at least a portion of the second support portion 123 are disposed in the gap between the side plate 120 and the outdoor heat exchanger 500.

By placing at least a first support portion 121 and at least a portion of a second support portion 123 in the gap between the side plate 120 and the outdoor heat exchanger 500, the first support portion 121 and the second support portion 123 support the outdoor heat exchanger 500, preventing the outdoor heat exchanger 500 from colliding with the side plate 120 during the transportation of the outdoor air conditioning unit.

In some embodiments, as shown in Figures 3, 4 and 8, the outdoor heat exchanger 500 is provided with an end plate 510. The end plate 510 is located at the end of the outdoor heat exchanger 500 and is connected to the partition plate 320 so that the partition plate 320 constrains the outdoor heat exchanger 500 and increases the stability of the outdoor heat exchanger 500 installation.

In some embodiments, as shown in Figures 3, 4, and 8, the end plate 510 typically extends along the height direction of the housing 100 and is typically intersecting with the partition plate 320. To facilitate connection between the end plate 510 and the partition plate 320, the end plate 510 is provided with an extension. The extension may be located on the side of the end plate 510 closest to the partition plate 320. The extension may be correspondingly positioned with and in contact with the partition plate 320. The extension is connected to the partition plate 320 by fasteners, so that the partition plate 320 constrains the outdoor heat exchanger 500.

In some embodiments, as shown in FIG8, the extension is provided with a fifth connecting hole, and the partition 320 is provided with a sixth connecting hole. The sixth connecting hole is provided in correspondence with the fifth connecting hole, and the same fastener is provided in the fifth connecting hole and the sixth connecting hole so that the end plate 510 and the partition 320 are connected to each other.

In some embodiments, multiple fifth connecting holes are provided, and these multiple fifth connecting holes can be distributed along the height direction of the housing 100. Correspondingly, multiple sixth connecting holes are also provided, and these multiple sixth connecting holes can be distributed along the height direction of the housing 100. The multiple sixth connecting holes and the multiple fifth connecting holes are respectively provided to enhance the connection effect between the end plate 510 and the partition 320.

In some embodiments, as shown in Figures 2 and 8, the end plate 510 is connected to the top cover 110 to constrain the outdoor heat exchanger 500 and increase the stability of the outdoor heat exchanger 500 installation.

In some embodiments, as shown in Figures 4 and 6, the end plate 510 is provided with a connecting portion 511. The connecting portion 511 may be disposed near the top of the end plate 510. The connecting portion 511 and the first bent portion 112 may be connected to each other by fasteners so that the end plate 510 and the top cover 110 are connected to each other.

In some embodiments, as shown in Figures 4, 6, and 20, since the outdoor heat exchanger 500 is disposed within the receiving cavity, and the end plate 510 is connected to the outdoor heat exchanger 500, the end plate 510 is also typically disposed within the receiving cavity. The first bend 112 is located outside the partition 320, and the connecting portion 511 needs to pass through the partition 320 when connecting to the first bend 112. Therefore, the partition 320 is provided with a clearance portion 322, through which the connecting portion 511 can pass and connect to the first bend 112 via fasteners.

It should be noted that, since the connecting part 511 needs to pass through the partition 320 and connect with the first bending part 112, there is a gap between the connecting part 511 and the outdoor heat exchanger 500 in the horizontal direction.

In some embodiments, as shown in FIG20, the clearance portion 322 is provided in the notch at the upper end of the partition 320.

In some embodiments, as shown in Figures 7 and 17, the outdoor unit of a top-discharge air conditioner includes a compressor 600. The compressor 600 is disposed within a housing cavity. The compressor 600 is used to compress refrigerant in a low-temperature, low-pressure state to a high-temperature, high-pressure state. The compressor 600, the outdoor heat exchanger 500, and the indoor heat exchanger together form a refrigerant circulation loop, in which the refrigerant flows to achieve cooling or heating of the indoor environment by the air conditioner.

In some embodiments, as shown in Figures 2 and 7, the heat exchange fan 400 is located above the compressor 600 and below the air outlet 101.

In some embodiments, as shown in Figures 2 and 7, the compressor 600 is located in the middle part of the chassis 130, and the outdoor heat exchanger 500 is located on the outer edge of the chassis 130. The outdoor heat exchanger 500 surrounds the compressor 600, which on the one hand increases the area of the outdoor heat exchanger 500 and enhances its heat exchange effect; on the other hand, it allows the outdoor heat exchanger 500 to be located close to the air inlet 102 so that the air entering the casing 100 can contact the outdoor heat exchanger 500 in a timely manner, thereby enhancing its heat exchange effect.

In the above-mentioned top-discharge air conditioner outdoor unit, the fasteners connecting the side plate 120 and the top cover 110, and the fasteners connecting the side plate 120 and the chassis 130 are subjected to small shear forces, and the side plate 120 is firmly and reliably connected to the top cover 110 and the chassis 130; in addition, the side plate 120 and the first bend 112 and the side plate 120 and the second bend 131 adopt "point contact", so the side plate 120 is less damaged during transportation.

The top-discharge outdoor unit of the air conditioner provided in this disclosure can also be used to solve the connection problem between the fan cover and the heat exchanger. The fan cover typically includes an air outlet grille and a connector. The air outlet grille is located at the air outlet of the casing, and air inside the casing is output to the outside of the casing through the air outlet grille. The connector is located at the top of the air outlet grille, and the heat exchanger is connected to the connector. Because the connector is subjected to the weight of the heat exchanger, the connection between the connector and the air outlet grille is prone to damage, affecting the normal operation of the heat exchanger. Furthermore, since the air outlet of the casing faces upwards, the heat exchanger is usually connected to a rain cover to prevent rainwater from affecting its normal operation. In the prior art, the rain cover is usually located on top of the heat exchanger, below the air outlet grille, and connected to the connector, which increases the complexity of the overall structure and reduces assembly efficiency. Therefore, the fan cover in the prior art cannot adequately meet the requirements of the top-discharge indoor unit of the air conditioner.

To solve the above problems, as shown in Figure 1, the top-discharge air conditioner outdoor unit provided in this embodiment includes a housing 100, which includes an air outlet 101 and an air inlet 102.

In some embodiments, the air outlet 101 of the housing has a circular opening direction and is located in the middle part of the top cover 110.

As shown in Figures 1, 2, and 3, the chassis 130, side plate 120, and top cover 110 together define a receiving cavity 10. The receiving cavity 10 is used to accommodate components such as the outdoor heat exchanger 500, compressor 600, and heat exchange fan 400, which are located inside the housing 100. The air inlet 102 and air outlet 101 are respectively connected to the receiving cavity 10.

As shown in Figure 3, the outdoor unit of the top-discharge air conditioner includes an outdoor heat exchanger 500, which is located inside the casing 100; the outdoor heat exchanger 500 is located near the air inlet 102.

As shown in Figure 2, the top-discharge outdoor unit of the air conditioner includes a heat exchange fan 400, which is located inside the housing cavity and positioned near the air outlet 101 of the casing. The heat exchange fan 400 is located below the air outlet 101.

As shown in Figure 21, the heat exchange fan 400 includes fan blades 410, which are used to drive airflow.

As shown in Figure 22, the heat exchange fan 400 includes a motor 420, and fan blades 410 are connected to the output shaft of the motor 420. The motor 420 is located below the top cover 110, and the output shaft of the motor 420 is set downward. The motor 420 is used to drive the fan blades 410 to rotate.

In some embodiments, as shown in Figures 2 and 7, the compressor 600 is located below the heat exchange fan 400 so that the heat exchange fan 400 can be positioned close to the air outlet 101.

In some embodiments, as shown in Figures 1, 21 and 22, the top-discharge air conditioner outdoor unit includes a fan cover 200, which is located at the air outlet 101 and installed on the top cover 110.

In some embodiments, as shown in FIG23, the top cover 110 is provided with a recessed portion 113, which is recessed into the upper surface of the housing 100 to increase the overall strength of the top cover 110. The air outlet 101 can be provided through the recessed portion 113 along the height direction of the housing 100.

In some embodiments, as shown in FIG23, the top cover 110 is a sheet metal part, and the recessed portion 113 can be formed by stamping the top cover 110 toward the interior of the receiving cavity. Forming the recessed portion 113 by stamping can simplify the manufacturing process of the recessed portion 113 and improve production efficiency.

It should be noted that when the sunken part 113 is produced by stamping, as shown in Figure 24, the top cover 110 has a stepped part 114 on the side facing the receiving cavity, which corresponds to the sunken part 113.

In some embodiments, as shown in FIG23, the recessed portion 113 has a dimension of 10 mm along the height direction of the housing 100.

In some embodiments, as shown in Figures 21 and 25, the fan shroud 200 includes an air outlet grille 210. The air outlet grille 210 is located at the air outlet 101. The air outlet grille 210 defines an air outlet portion 2101, which communicates with the air outlet 101. By operating the heat exchange fan 400, air from outside the receiving cavity is introduced into the receiving cavity through the air inlet 102, and then output to the outside of the receiving cavity through the air outlet 101 and the air outlet portion 2101.

In some embodiments, as shown in Figures 23 and 25, the air outlet grille 210 is disposed within the recessed portion 113, which can hide the air outlet grille 210, thereby increasing the aesthetics of the top-outlet air conditioner outdoor unit.

In some embodiments, as shown in Figures 25 and 26, the air outlet grille 210 is spirally arranged in the horizontal direction to reduce noise when air passes through the air outlet grille 210. Experiments on the air outlet grille 210 show that the noise of the spiral air outlet grille 210 is reduced by 2 dB compared to the square air outlet grille 210.

In some embodiments, as shown in Figures 25 and 26, the air outlet grille 210 includes grille bars that are bent in a horizontal plane to form a spiral shape, with a gap between adjacent spiral lines to form an air outlet 2101.

In other embodiments, the grille bars can be made of iron wire, which not only makes it easier to bend the grille bars, but also increases the strength of the air outlet grille 210.

In some embodiments, as shown in Figures 25 and 26, the fan shroud 200 includes a frame disposed on the top of the housing, and the frame is disposed corresponding to the air outlet 101. The frame can be used to fix the air outlet grille 210; the frame is disposed in the recessed portion 113 so that the upper surface of the recessed portion 113 can support the frame, thereby increasing the connection strength between the frame and the air outlet grille 210.

In some embodiments, as shown in Figures 25 and 26, the air vent grille 210 is connected to the top of the frame so that the frame supports the air vent grille 210, thereby increasing the connection strength between the air vent grille 210 and the frame.

In some embodiments, the air outlet grille 210 is welded to the frame. The frame and the air outlet grille 210 are connected by welding, which not only facilitates the connection between the air outlet grille 210 and the frame, but also increases the connection strength between the air outlet grille 210 and the frame.

In some embodiments, as shown in Figures 27 and 28, the frame includes a first frame 220, which is connected to the bottom of the air outlet grille 210. When the air outlet grille 210 is spiral-shaped, the connection of the first frame 220 to the air outlet grille 210 can also prevent the grille bars from springing back and deforming, ensuring the reliability of the grille bars bending into a spiral shape.

In some embodiments, as shown in Figures 27 and 28, a plurality of first frames 220 are provided, and the plurality of first frames 220 are distributed along the circumference to increase the connection strength between the first frames 220 and the air outlet grille 210.

In some embodiments, as shown in Figures 27 and 28, eight first skeletons 220 are provided, and the eight first skeletons 220 are distributed in a circumferential array, with gaps between adjacent first skeletons 220.

It should be noted that, for ease of description, the ends of adjacent first skeletons 220 that are close to each other are defined as the inner end of the first skeleton 220, and the ends of adjacent first skeletons 220 that are far apart from each other are defined as the outer end of the first skeleton 220.

In some embodiments, the first frame 220 is made of iron wire to increase its strength. The diameter of the first frame 220 may be larger than the diameter of the grid bars.

In some embodiments, as shown in Figures 27 and 28, the frame includes a second frame 230, which is connected to the outer end of the first frame 220. The second frame 230 is disposed in the recessed portion 113 and contacts the upper surface of the recessed portion 113 so that the recessed portion 113 supports the second frame 230, thereby increasing the firmness of the connection between the frame and the top cover 110.

In some embodiments, the second skeleton 230 has a ring structure, and the first skeleton 220 may be disposed inside the second skeleton 230.

In some embodiments, as shown in Figures 23 and 28, the shape of the recessed portion 113 in the horizontal plane is adapted to the shape of the second frame 230 in the horizontal plane to locate the connection position between the frame and the top cover 110.

In some embodiments, as shown in FIG27, the second frame 230 is provided with a first connecting part 231, and the first connecting part 231 may be connected with a fastener. The first connecting part 231 can be connected to the top cover 110 through the fastener so that the second frame 230 is fixed to the top cover 110.

In some embodiments, as shown in Figures 23, 24, and 27, the top cover 110 is provided with a second connecting portion 115, which may be located in the recessed portion 113 and may correspond to the first connecting portion 231. Fasteners may be sequentially provided in the first connecting portion 231 and the second connecting portion 115, so that the second frame 230 is located within the recessed portion 113.

In some embodiments, as shown in Figures 24 and 27, four first connecting portions 231 are provided, corresponding to the four corners of the top cover 110. Four second connecting portions 115 are also provided, corresponding to the four first connecting portions 231, to increase the robustness of the connection between the frame and the top cover 110.

In other embodiments, the first connecting portion 231 is provided with a first connecting hole, and the second connecting portion 115 is provided with a second connecting hole, with the second connecting hole corresponding to the first connecting hole. The fastener is a bolt or screw, etc., which is provided in both the first connecting hole and the second connecting hole to connect the second frame 230 and the top cover 110.

In some embodiments, as shown in FIG27, the second frame 230 is a square structure with arc-shaped corners, and the first connecting part 231 is provided at the arc-shaped corner of the second frame 230.

In some embodiments, the second frame 230 is made of iron wire to increase the strength of the second frame 230.

In other embodiments, the first connecting part 231 is formed by extruding a portion of the second frame 230 along the height direction of the housing 100, thereby increasing the area of the portion of the second frame 230 in the horizontal plane and thinning its dimensions along the height direction of the housing 100. This method simplifies the manufacturing process of the first connecting part 231, eliminates the need to waste other materials, reduces costs, and allows the first connecting part 231 to be integrally formed with the second frame 230, reducing the number of components in the top-discharge air conditioner indoor unit and improving assembly efficiency.

In the disclosed embodiment, by designing the frame to include a first frame 220 and a second frame 230, multiple first frames 220 are connected to the air outlet grille 210 to increase the connection strength between the frame and the air outlet grille 210; the second frame 230 is made to contact the top cover 110 so that the top cover 110 supports the frame, thereby increasing the connection strength between the frame and the top cover 110; by designing the second frame 230 as a closed ring structure, multiple first frames 220 are circumferentially distributed and connected to the second frame 230 to increase the overall strength of the frame, thereby increasing the connection and fixing effect of the frame on the air outlet grille 210 and the connector 240, and thus increasing the overall strength of the fan cover 200.

In some embodiments, as shown in Figures 28 and 30, the fan shroud 200 includes a connector 240 connected to the inner end of the first frame 220. The connector 240 is used to mount the heat exchange fan 400. The motor 420 is connected to the connector 240 via fasteners 430.

In some embodiments, as shown in FIG26, the connector 240 is located in the middle portion of the fan shroud 200.

In some embodiments, as shown in FIG26, the connector 240 includes a connector body located above the frame, and the motor 420 is connected to the connector body by fasteners 430 so that the heat exchange fan 400 can be disposed in the receiving cavity and located below the air outlet 101.

In some embodiments, as shown in FIG30, a motor connecting portion 421 is provided on the outer periphery of the motor 420, and a fastener 430 is connected to the motor connecting portion 421 to connect the fastener 430 to the motor 420. The fastener 430 can sequentially pass through the gap between the connector body and the adjacent first frame 220 to connect to the motor 420. It should be noted that the fastener 430 can be a bolt or screw or other components.

As shown in Figures 30, 31, and 32, the connector 240 includes a rainproof portion 241, which can be located at the outer edge of the connector 240. The rainproof portion 241 can be formed by bending the outer edge of the connector 240 downwards. The rainproof portion 241 can be connected to the outer edge of the connector body, with the end of the rainproof portion 241 away from the connector body facing downwards. When the motor 420 is connected to the connector body, the rainproof portion 241 is located on the outer periphery of the motor 420 and on the outer periphery of the top of the heat exchange fan 400 to protect the motor 420 and prevent rainwater from contacting it.

In some embodiments, as shown in Figures 31 and 32, the connector body and the rainproof part 241 together form a protective cavity 243, and the top of the motor 420 is disposed within the protective cavity 243 so that the connector 240 protects the motor 420. The rainproof part 241 can be integrally formed with the connector body to reduce the number of components in the top-discharge air conditioner indoor unit and improve assembly efficiency.

In some embodiments, as shown in Figures 28 and 32, the rainproof part 241 is provided with a through part 242, the opening direction of the through part 242 is arranged in a horizontal direction, and the first frame 220 is disposed through the rainproof part 241 so that the frame and the connector 240 are connected to each other.

It should be noted that at least a portion of the first frame 220 passes through the through portion 242 and is disposed within the protective cavity 243, while the motor 420 is located below the first frame 220. In some embodiments, the through portion 242 is disposed close to the connector body to minimize the space occupied by the first frame 220 within the protective cavity 243.

Since the air outlet grille 210 is located at the top of the frame, and the connector body is located above the frame, the first frame 220 passes through the rainproof part 241. Therefore, in order to prevent the air outlet grille 210 and the connector 240 from interfering with each other, the air outlet grille 210 is provided with a first clearance part 2102, as shown in Figures 26 and 34. The first clearance part 2102 is provided along the height direction of the housing 100; the connector 240 is located at the first clearance part 2102.

The top-discharge air conditioner outdoor unit of this embodiment provides a rainproof part 241 at the outer edge of the connector 240, which waterproofs and protects the heat exchange fan 400 from rain, thus eliminating the need for a rain cover. This simplifies the overall structure, reduces the number of components in the top-discharge air conditioner indoor unit, improves assembly efficiency, and reduces the number of fasteners 430 used during assembly. By placing the air outlet grille 210 above the frame, the frame not only fixes the air outlet grille 210 but also supports it, increasing the connection strength between the air outlet grille 210 and the frame. By connecting the connector 240 to the frame, the frame not only installs and fixes the connector 240 but also supports it, thereby increasing the fixing effect of the fan cover 200 on the connector 240, and thus increasing the fixing effect of the heat exchange fan 400.

In the top-discharge air conditioner outdoor unit of this embodiment, the fan cover 200 not only has high overall strength and good fixing effect on the heat exchange fan 400, but also has fewer overall parts and higher assembly efficiency.

The top-discharge air conditioner outdoor unit of this disclosure can also be used to solve the strength problem of the fan cover. The fan cover typically includes a connecting plate and an air outlet grille. The connecting plate is used to connect the heat exchanger fan, and air inside the casing is output to the outside of the casing through the air outlet and the air outlet grille. In the prior art, the middle part of the air outlet grille usually has a mounting part, and the connecting plate is located at the mounting part to connect the connecting plate to the air outlet grille. Because the connecting plate is subjected to the gravity of the heat exchanger fan, the connection between the connecting plate and the air outlet grille is prone to damage, affecting the normal operation of the heat exchanger fan. Currently, the strength of the fan cover cannot adequately meet the requirements of the heat exchanger fan.

To solve the above problems, as shown in FIG35, the top-discharge air conditioner outdoor unit provided in this embodiment includes a housing 100, and the housing 100 includes an air outlet 101 and an air inlet 102.

In some embodiments, as shown in FIG38, the top-discharge outdoor unit of the air conditioner includes a fan cover 200, which is located at the air outlet 101 and connected to the top cover 110. The fan cover 200 provides protection for the heat exchange fan 400, protecting the fan blades 410 and preventing damage to the fan or accidental injury caused by the intake of indoor debris. The fan cover 200 can also concentrate and uniformly guide the airflow, making the airflow blown by the fan more concentrated and uniform.

In some embodiments, as shown in Figures 37 and 39, the fan cover 200 includes an air outlet grille 210, which is disposed at the air outlet 101. The air outlet grille 210 defines an air outlet portion 2101, which communicates with the air outlet 101. Air in the receiving cavity 10 is output to the outside of the receiving cavity 10 through the air outlet 101 and the air outlet grille 210.

In some embodiments, as shown in FIG39, the fan shroud 200 includes a connecting plate 250. The connecting plate 250 is located in the middle part of the fan shroud 200. The connecting plate 250 may be disposed on the top of the air outlet grille 210, the heat exchange fan 400 may be located below the connecting plate 250, and the motor 420 may be connected to the connecting plate 250.

In some embodiments, the connecting plate 250 is detachably connected to the heat exchange fan 400 via a locking member 440. The locking member 440 is a component such as a bolt or screw. The locking member 440 can pass through the connecting plate 250 and the air outlet grille 210 in sequence and be connected to the heat exchange fan 400. The heat exchange fan 400 is connected to the connecting plate 250 via the locking member 440 so that the heat exchange fan 400 can be disposed in the receiving cavity and located below the air outlet 101.

In some embodiments, the connecting plate 250 is provided with a connecting hole, which can extend along the height direction of the housing 100, and the locking member 440 can pass through the connecting hole and the air outlet 2101 in sequence to connect with the heat exchange fan 400.

In some embodiments, as shown in FIG39, the connecting plate 250 is square.

In some embodiments, as shown in Figures 39 and 40, four locking members 440 are provided, and four connecting holes are also provided accordingly. The four connecting holes are located at the four corners of the connecting plate 250 to ensure that the connecting plate 250 and the motor 420 are subjected to uniform force, thereby increasing the firmness and reliability of the connection between the motor 420 and the connecting plate 250.

Since the heat exchanger 400 is connected to the connecting plate 250, and the connecting plate 250 is located above the air outlet grille 210, at least part of the weight of the heat exchanger 400 will be transferred to the air outlet grille 210, which places high demands on the strength of the air outlet grille 210.

In some embodiments, as shown in Figures 39, 41, and 43, the air outlet grille 210 includes a frame 213. The frame 213 can be mounted on the top cover 110. The frame 213 can be located at the outer edge of the air inlet 102.

In other embodiments, the frame 213 may be enclosed by wire to form a closed square.

In some embodiments, as shown in Figures 40, 41, and 44, the air vent grille 210 includes a first support member 211 connected to the frame 213. Multiple first support members 211 may be configured, and at least some of the first support members 211 may be distributed along a first direction, wherein the first direction is horizontal.

In some embodiments, the diameter of the first support member 211 is 3 mm.

In some embodiments, the first support member 211 is made of iron wire to give the first support member 211 higher strength.

In some embodiments, the first support member 211 is welded to the frame 213 to increase the connection strength between the first support member 211 and the frame 213.

There needs to be a certain gap between adjacent first support members 211 so that air passing through the air outlet 101 can be output to the outside of the receiving cavity through the gap between adjacent first support members 211. When the gap is too large, fingers can easily stick into the receiving cavity through the gap, posing a safety hazard. Moreover, a large gap can also reduce the strength of the air outlet grille 210. When the gap is too small, the first support member 211 has a strong obstruction effect on the air, which can easily reduce the air outlet area of the air outlet grille 210, thereby reducing the air volume of the air outlet grille 210.

In some embodiments, as shown in Figures 40 and 41, the gap between adjacent first support members 211 is 9 mm to prevent fingers from being inserted into the receiving cavity through the air outlet 2101, and to allow the air outlet grille 210 to have a larger air outlet area and air volume.

In some embodiments, as shown in Figures 40 and 41, the lengths and diameters of the plurality of first support members 211 are the same, so as to improve the adaptability of the first support members 211, reduce the processing steps in the processing process, and improve processing efficiency.

In some embodiments, as shown in Figures 37 and 41, a first support member 211 is disposed on the side of the frame 213 away from the receiving cavity 10, so that the frame 213 supports the first support member 211, thereby increasing the reliability of the connection between the first support member 211 and the frame 213.

In some embodiments, as shown in Figures 43 and 46, the air outlet grille 210 includes a second support member 214 connected to the frame 213; the second support member 214 and the first support member 211 are arranged to cross each other to increase the strength of the air outlet grille 210.

In some embodiments, as shown in Figures 43 and 44, the second support member 214 can be configured as a plurality of them, with at least a portion of the second support members 214 distributed along a second direction. The second direction and the first direction are both horizontal directions, and the second direction intersects with the first direction.

By connecting the first support member 211 and the second support member 214 to the frame 213 respectively, the frame 213 constrains and fixes the first support member 211 and the second support member 214, thereby allowing the first support member 211 and the second support member 214 to be reliably arranged to cross each other, increasing the strength of the air outlet grille 210.

In some embodiments, as shown in FIG43, the diameter of the first support member 211 is less than or equal to the diameter of the second support member 214, so that the second support member 214 serves as an important support frame for the air outlet grille 210.

In some embodiments, the diameter of the second support member 214 is 8.6 mm.

In some embodiments, as shown in FIG46, at least five second support members 214 are provided so that the second support members 214 have a better supporting effect on the first support member 211, thereby increasing the strength of the air outlet grille 210.

There is a certain gap between adjacent second support members 214 so that the air passing through the air outlet 101 can be output to the outside of the receiving cavity through the gap between adjacent second support members 214. If the gap is too small, the second support member 214 will block the gap between adjacent first support members 211, reducing the air outlet area and air volume of the air outlet grille 210.

It should be noted that when the second support member 214 plays a major supporting role for the air outlet grille 210, the number of the second support member 214 is usually less than the number of the first support member 211. When the gap between adjacent first support members 211 is 9mm, fingers can no longer be inserted into the receiving cavity through the gap. At this time, the gap between adjacent second support members 214 does not need to be set too much.

It should also be noted that, as shown in Figure 43, the gap between adjacent first support members 211 and the gap between adjacent second support members 214 together define the air outlet 2101.

In some embodiments, the second support member 214 is made of iron wire to give the second support member 214 higher strength.

In some embodiments, the second support member 214 is welded to the frame 213 to increase the connection strength between the second support member 214 and the frame 213.

In some embodiments, as shown in FIG43, a first support member 211 is disposed on top of a second support member 214 so that the second support member 214 supports the first support member 211.

In some embodiments, as shown in FIG43, the second support member 214 is disposed within the frame 213 to increase the connection strength between the second support member 214 and the frame 213.

In some embodiments, the length and diameter of the plurality of second support members 214 are the same to improve the adaptability of the second support members 214, reduce the number of processing steps in the processing process, and improve processing efficiency.

To increase the connection strength between the connecting plate 250 and the air outlet grille 210, the connecting plate 250 is disposed above at least part of the intersection of the first support member 211 and the second support member 214, so that the first support member 211 and the second support member 214 can support the connecting plate 250, and the weight of the heat exchange fan 400 can be distributed to the first support member 211 and the second support member 214, thereby increasing the connection strength between the connecting plate 250 and the air outlet grille 210.

In some embodiments, as shown in Figures 45 and 46, the air vent grille 210 includes a reinforcing member 212 connected to the frame 213 to increase the strength of the air vent grille 210.

In some embodiments, at least one reinforcing member 212 is provided to increase the strength enhancement effect of the reinforcing member 212 on the air outlet grille 210.

As shown in Figure 44, when there is one reinforcing member 212, the reinforcing member 212 is located in the middle part of the frame 213 along the first direction so that the reinforcing member 212 can have a better reinforcing effect on the air outlet grille 210; when there are multiple reinforcing members 212, the multiple reinforcing members 212 are distributed along the first direction.

In some embodiments, a reinforcing member 212 is provided on the side of the air outlet grille 210 facing the receiving cavity to further increase the strength of the air outlet grille 210.

It should be noted that, since the first support member 211 and the reinforcing member 212 are respectively provided on opposite sides of the frame 213, the reinforcing member 212 may be provided in relation to the gap between two adjacent first support members 211, which can block air. In order to solve this problem, in some embodiments, there is a large gap between two adjacent first support members 211, and the reinforcing member 212 is provided between the two adjacent first support members 211 to prevent the reinforcing member 212 from blocking the gap between two adjacent first support members 211 in the height direction of the housing 100.

In some embodiments, the reinforcing member 212 is an iron wire.

In some embodiments, as shown in FIG44, the length direction of the reinforcing member 212 is arranged along the second direction, the length direction of the first support member 211 is arranged along the second direction, and the length direction of the second support member 214 is arranged along the first direction, so that the reinforcing member 212, the first support member 211 and the second support member 214 are respectively arranged to cross each other.

In some embodiments, as shown in FIG47, the top cover 110 is provided with a recessed portion 113, which is recessed into the upper surface of the housing 100. The air outlet 101 is provided through the recessed portion 113 along the height direction of the housing 100, and the air outlet grille 210 is located inside the recessed portion 113 so that the recessed portion 113 hides the air outlet grille 210, thereby increasing the aesthetics of the outdoor unit.

In this embodiment, the air outlet grille 210 is generally quadrilateral, and the four corners of the air outlet grille 210 are respectively provided with a first connecting part 231, and the recessed part 113 is provided with a second connecting part 115. The second connecting part 115 is correspondingly provided with the first connecting part 231. The first connecting part 231 and the second connecting part 115 are connected with the same fastener so that the air outlet grille 210 and the top cover 110 are connected to each other.

It should be noted that fasteners are components such as bolts or screws.

In some embodiments, the first connecting part 231 is provided with a first connecting hole, and the second connecting part 115 is provided with a second connecting hole. The second connecting hole is provided in correspondence with the first connecting hole, and fasteners are provided in both the first connecting hole and the second connecting hole so that the air outlet grille 210 and the top cover 110 are connected to each other.

In some embodiments, the size of the recessed portion 113 in the horizontal plane is larger than the opening size of the air outlet 101 in the horizontal plane. When the second connecting portion 115 and the first connecting portion 231 are connected to each other by fasteners, the recessed portion 113 supports the outer edge of the air outlet grille 210 to increase the connection strength between the air outlet grille 210 and the top cover 110.

In some embodiments, as shown in Figures 43 and 47, the first connecting portion 231 is disposed on the second support member 214, and the second connecting portion 115 is disposed on the outer edge of the air outlet 101.

Since the first connecting part 231 is located on the second support member 214, and the second support member 214 is located at the bottom of the first support member 211, the first support member 211 may interfere with the first connecting part 231. Therefore, as shown in FIG43, the first support member 211 is provided with a second clearance part 2111. The second clearance part 2111 is correspondingly provided with the first connecting part 231. The fastener passes through the second clearance part 2111 and is located on the first connecting part 231 to prevent the first support member 211 from interfering with the fastener connection between the air outlet grille 210 and the top cover 110.

It should be noted that when multiple second support members 214 are provided, not all second support members 214 need to be provided with the first connecting part 231. The first connecting part 231 is only provided on the second support member 214 corresponding to the corner of the air outlet grille 210 to meet the installation requirements of the air outlet grille 210. Similarly, not all first support members 211 need to be provided with the second clearance part 2111. The second clearance part 2111 is only provided on the first support member 211 corresponding to the first connecting part 231 to meet the requirements.

In some embodiments, as shown in Figures 44, 46 and 49, the second clearance portion 2111 is formed by bending a first support member 211 near the first connecting portion 231 in a direction away from the first connecting portion 231 along a first direction.

The working principle of the top-outlet air conditioner outdoor unit of this embodiment is as follows: the outdoor air is introduced into the receiving cavity through the air inlet 102 by the operation of the heat exchange fan 400, and after heat exchange by the outdoor heat exchanger 500, it is output to the outside of the receiving cavity 10 through the air outlet 101 and the air outlet grille 210.

The top-discharge air conditioner outdoor unit of this embodiment uses a first support member 211 and a second support member 214 arranged crosswise, and a frame 213 constrains and fixes the first support member 211 and the second support member 214, so that the first support member 211, the second support member 214 and the frame 213 are connected to form an air outlet grille 210; by placing the first support member 211 on the top of the frame 213, the frame 213 supports the first support member 211, thereby increasing the reliability and firmness of the connection between the first support member 211 and the frame 213, thereby increasing the strength of the air outlet grille 210.

The top-discharge air conditioner outdoor unit of this embodiment is equipped with a reinforcing member 212, which is connected to the frame 213 to increase the strength of the frame 213. The reinforcing member 212 and the first support member 211 are respectively arranged on opposite sides of the frame 213, and the gap between the two first support members 211 corresponding to the reinforcing member 212 is increased so that the reinforcing member 212 is arranged between the two first support members 211 to prevent the reinforcing member 212 from affecting the air outlet effect.

The top-discharge air conditioner outdoor unit of this embodiment sets the gap between two adjacent first support members 211 to 9mm, which can prevent fingers from being inserted into the receiving cavity through the gap while ensuring that the air outlet grille 210 has a large air outlet area and air volume.

The top-discharge air conditioner outdoor unit of this embodiment places the connecting plate 250 at a partial intersection of the first support member 211 and the second support member 214, so that the first support member 211 and the second support member 214 can share the weight of the heat exchange fan 400 on the connecting plate 250, thereby increasing the support effect of the air outlet grille 210 on the connecting plate 250.

The top-discharge air conditioner outdoor unit of this disclosure improves the compatibility between the first support members 211 and the second support members 214 by designing the diameter and length of the multiple first support members 211 to be the same size, and the diameter and length of the multiple second support members 214 to be the same size, thereby reducing the number of processing steps and improving processing efficiency.

The top-discharge air conditioner outdoor unit of this embodiment has a recessed portion 113 in the top cover 110 so that the air outlet grille 210 is located in the recessed portion 113, preventing the air outlet grille 210 from protruding from the top of the top cover 110 and ensuring the aesthetics of the air conditioner outdoor unit; and a first connecting portion 231 is provided at the four corners of the air outlet grille 210 and a second connecting portion 115 is provided at the corresponding position in the recessed portion 113, so that fasteners are sequentially provided in the first connecting portion 231 and the second connecting portion 115, so that the air outlet grille 210 is installed on the top cover 110, reducing the risk of deformation caused by the small contact area between the air outlet grille 210 and the top cover 110.

Those skilled in the art will understand that the scope of this disclosure is not limited to the specific embodiments described above, and that modifications and substitutions can be made to certain elements of the embodiments without departing from the spirit of this disclosure. The scope of this disclosure is limited by the appended claims.
