The wall-mounted air conditioner indoor unit provided by the embodiment of the present invention, as shown in FIG. 2, comprises a casing 1 , and the casing 1 is provided with an air inlet 11 and an air outlet 12, and the casing 1 is provided with a fan 2 and heat exchange. The heat exchanger 3 is disposed obliquely, and one end of the heat exchanger 3 adjacent to the front panel 13 of the casing 1 is the top end of the heat exchanger 3, and the heat exchanger 3 is close to the rear wall 14 of the casing 1. One end is the bottom end of the heat exchanger 3, the fan 2 is located below the heat exchanger 3, and the water receiving tray 4 is located below the bottom end of the heat exchanger 3.

In the wall-mounted air conditioner indoor unit of the embodiment of the present invention, as shown in FIG. 2, the heat exchanger 3 is disposed obliquely, and the top end of the heat exchanger 3 is close to the front panel 13 of the casing 1, and the bottom end of the heat exchanger 3 is close to the casing. 1 Rear wall 14, the fan 2 is arranged under the heat exchanger 3, and then the indoor air is driven by the fan 2 to enter the air inlet 11, exchange temperature with the heat exchanger 3, and then blow out by the air outlet 12 to realize the adjustment of the indoor temperature. . Since the heat exchanger 3 is disposed obliquely, the condensed water formed on the heat exchanger 3 flows toward the bottom end of the heat exchanger 3. Therefore, only one water receiving tray 4 needs to be disposed below the bottom end of the heat exchanger 3 The collection of condensed water, so that only one drainage pipeline is required, and the heat exchanger 3 which is inclined is simpler than the heat exchanger of the inverted V-shaped structure, and therefore, the air conditioner is simplified compared with the prior art. The structure, making and installation of the indoor unit is convenient.

Since the condensed water is generated on the heat exchanger 3, it will flow down the heat exchanger 3 if it is changed The top end of the heat exchanger 3 is close to and in contact with the front panel 13 of the casing 1, and the condensed water generated at the top end of the heat exchanger 3 may flow downward along the front panel 13 of the casing 1, causing the condensed water not to be properly collected and discharged indoors. Outside the machine, therefore, as shown in FIG. 2, there is a gap between the upper end of the heat exchanger 3 and the front panel 13, thereby avoiding the problem that the condensed water generated at the top end of the heat exchanger 3 cannot smoothly enter the water receiving tray. Since the fan 2 needs to perform a rotational motion, the fan 2 and the front panel 13 also have a gap. Thus, in order to make the overall structure of the indoor unit lighter and thinner, referring to FIG. 2, the gap between the upper end of the heat exchanger 3 and the front panel 13 is greater than or equal to the gap between the fan 2 and the front panel 13. Thus, the width of the heat exchanger 3 in the direction toward the front panel 13 does not exceed the outer contour of the fan 2 in the direction of the front panel 13, saving space in the thickness direction of the casing 1, whereas the heat exchanger 02 of the prior art The inverted V-shaped structure is disposed around the blower 03, and the width of the heat exchanger 02 in the direction toward the air conditioner front panel exceeds the outer contour of the blower 03. Therefore, the embodiment of the present invention makes the structure of the air conditioner indoor unit compared with the prior art. More light and thin.

The gap between the upper end of the heat exchanger 3 and the front panel 13 is greater than or equal to the gap between the fan 2 and the front panel 13, and the heat exchanger 3 does not surround the fan 2, saving space in the thickness direction of the casing 1, wherein The heat exchanger 3 may be a heat exchanger in the form of a flat plate, a curved plate or a multi-fold splicing, as long as the heat exchanger is always located on one side of the fan 2, and the heat exchanger 3 shown in FIG. 2 is A heat exchanger in the form of a splicing. However, in the actual installation, since the above two kinds of gaps are not well measured, referring to Fig. 2, the line connecting the top end and the bottom end of the heat exchanger 3 has an angle ? with the front panel 13. Thus, the value of the angle between the heat exchanger 3 and the front panel 13 is controlled during installation to achieve the control of the gap, and depending on the specific structure, for example, the shape and size of the fan 2, the specific shape of the heat exchanger 3, The length of the heat exchanger 3 and the front panel 13 is preferably 20 to 60 degrees.

In order to effectively increase the heat exchange effect of the heat exchanger 3 when the air flow generated by the fan 2 is working, the heat exchanger 3 can be located between the air inlet 11 and the air outlet 12. Generally, in order to facilitate the adjustment of the room temperature, The air outlet 11 is disposed at a position close to the front panel 13, so that the air that has undergone heat exchange can smoothly enter the room, and correspondingly, the air inlet 11 can be disposed on the rear wall or the top wall of the casing 1, but when the indoor unit After the wall is installed, the rear wall is blocked by the wall surface, and for the sake of beauty, it is often necessary to fit the ceiling of the indoor unit to the ceiling, and thus the top wall, so that the air inlet 11 provided on the rear wall or the top wall will It is blocked, so that the air intake is not smooth, resulting in poor heat exchange effect of the air conditioner indoor unit. Therefore, in order to solve the above problem, as shown in FIG. 2, the top wall of the casing 1 may include the inclined portion 15 which is inclined, and the air inlet 11 Opened on the inclined portion 15, the heat exchanger 3 and The air inlets 11 are opposed to each other, and the inclination angle of the inclined portion 15 coincides with the inclination angle of the heat exchanger 3. By using the slanting arrangement of the heat exchanger 3, the shape of the top wall of the casing 1 is inclined to the inclined portion 15 corresponding to the heat exchanger 3, and the air outlet 11 can be arranged on the inclined portion 12, so that when the air conditioning indoor unit is hung When the wall is installed, or the top wall abuts against the ceiling, the wall surface outside the inclined portion 12 does not contact the blocking inclined portion 12, and the air inlet 11 provided on the inclined portion 12 can smoothly enter the air. Therefore, the inclined portion 15 is provided. And the air inlet 11 is provided on the inclined portion 15, so that the position where the air-conditioning indoor unit wall is installed can be flexibly set as needed without affecting the heat exchange effect.

As shown in FIG. 2, the water receiving tray 4 is disposed below the bottom end of the heat exchanger 3 to collect condensed water, wherein the water receiving tray 4 may be disposed on a side close to the front panel 13, or disposed near the rear wall. One side of the 14th, however, as shown in Fig. 2, in comparison, the water receiving tray 4 is disposed near the side of the rear wall 14, and the collected condensed water can be directly discharged downward without affecting the front panel. The structure, in turn, facilitates the different aesthetic design of the front panel, and therefore, it is preferred that the water tray 4 be disposed adjacent the rear wall 14 of the housing 1.

Specifically, as shown in FIG. 3, the air outlet 12 is provided in the horizontal direction of the casing 1. The embodiment of the front and lower ends of the two ends, wherein the centrifugal fan 22 is two, respectively located at the lateral ends of the casing 1, the air inlet sides of the two centrifugal fans 22 are opposite, and the air outlets 12 are two, and are respectively opened at The front and lower ends of the lateral ends of the casing 1 and the outlet sides of the two centrifugal fans 22 are opposed to the two outlets 12, respectively. Thus, the flowing air enters from the air inlet 12, passes through the heat exchanger 3, and flows from the inside of the casing 1 to the both ends of the casing 1 by the two centrifugal fans 22, and then flows from the outlet side of the centrifugal fan. The air is blown to the air outlet 12, and is blown out from the air outlet 12 located at the front lower side of the lateral ends of the casing 1.

As shown in FIG. 4 and FIG. 5, in order to provide the air outlet 12 at the lateral end faces of the casing, the centrifugal fan 22 is one, located at one lateral end of the casing 1, and the centrifugal fan 22 faces the inside of the casing 1. The side is the air inlet side, and the air outlet 12 is opened in the casing 1 to be provided with one end surface of the centrifugal fan 22, and the air outlet 12 communicates with the air outlet side of the centrifugal fan 22 through the air outlet passage 5. Thus, the flowing air enters from the air inlet 12, passes through the heat exchanger 3, and then flows from the inside of the casing 1 to the both ends of the casing 1 by the centrifugal fan 22, and then is blown out by the air outlet side of the centrifugal fan. The air outlet passage 5 is blown out from the air outlet 12 which is provided at one end surface of the centrifugal fan 22 of the casing 1.

It should be noted that FIG. 4 is a schematic structural view of the centrifugal fan 22 when it is located at the lateral right end of the casing, and FIG. 5 is a structural schematic view of the centrifugal fan 22 when it is located at the lateral left end of the casing. Of course, it can also be at both ends of the casing 1 at the lateral ends.
