Referring to fig. 1-3, an embodiment of the present disclosure provides an air conditioner, including a housing 1, wherein the housing 1 includes a first air duct 10, a second air duct 20, and a communication portion 30. The air flow adjusting assembly 40 is rotatably arranged on the communication part 30 and is configured to block the communication part 30 to separate the first air channel 10 from the second air channel 20 when rotating to a first position and to communicate the first air channel 10 with the second air channel 20 when rotating to a second position.

The air flow can circulate in the first air channel 10 and also can circulate in the second air channel 20, and the second air channel 20 passes through the first air channel 10, so that the space occupied by the air channel is more compact, and the appearance design of the shell 1 is facilitated. The communication portion 30 is provided on a side wall of the second duct 20, and can communicate the first duct 10 and the second duct 20, thereby allowing air flow to circulate between the first duct 10 and the second duct 20. The airflow adjusting assembly 40 is disposed on the communicating portion 30 and can rotate relative to the communicating portion 30, and when the airflow adjusting assembly 40 rotates to a first position, the communicating portion 30 is blocked to separate the first air duct 10 from the second air duct 20, and when the airflow adjusting assembly rotates to a second position, the communicating portion 30 is conducted to communicate the first air duct 10 with the second air duct 20. In a state where the first air duct 10 and the second air duct 20 are separated, the air flows in the first air duct 10 and the second air duct 20 respectively circulate, and do not affect each other, and in a state where the first air duct 10 and the second air duct 20 communicate, the air flows can enter the second air duct 20 from the first air duct 10 or enter the first air duct 10 from the second air duct 20, and the air flows in the first air duct 10 and the second air duct 20 can be allocated.

With this embodiment, the air conditioner can respectively convey air flows through the first air duct 10 and the second air duct 20, the states of communication and separation between the first air duct 10 and the second air duct 20 can be adjusted, and the air supply effect of the first air duct 10 and the second air duct 20 is not cured but can be changed by adjusting the states.

Alternatively, the communicating portion 30 is an opening on a side wall of the second air duct 20. The side wall of the second air duct 20 is provided with an opening to realize the communication between the first air duct 10 and the second air duct 20. Alternatively, the shape of the opening is circular, oval, rectangular or trapezoidal. Through the openings of the above-described shapes, communication between the first and second air channels 20 can be achieved. Alternatively, the cross section of the second air duct 20 is circular, elliptical, rectangular or trapezoidal. The second air duct 20 with the circular, oval or rectangular cross section can enable air flow to pass smoothly, and the cross section shape of the second air duct 20 can be selected according to the distribution of the internal components of the shell, so that the spatial interference on other internal components is avoided. When the cross section is rectangular, the side wall of the second air duct 20 is a plane, and can be closer to the heat exchanger 50 in the air conditioner, so that the heat or cold emitted by the heat exchanger 50 can be used for air flow temperature adjustment. When the cross section is rectangular, the second air duct 20 is also convenient to communicate with the air outlet of the centrifugal fan.

In some embodiments, as shown in connection with FIG. 2, the airflow adjustment assembly 40 includes a shaft 41, a motor 42, and a baffle 43. The air conditioner comprises a communication part 30, a rotating shaft 41 rotatably arranged on the communication part 30, a motor 42 connected with the rotating shaft 41 to drive the rotating shaft 41 to rotate, a guide plate 43 fixedly connected with the rotating shaft 41 and configured to seal the communication part 30 when rotating to a first position and to conduct the communication part 30 when rotating to a second position.

The motor 42 drives the rotating shaft 41 to rotate, and then drives the guide plate 43 to rotate, when the guide plate 43 rotates to a first position, the communicating part 30 is blocked, so that the first air channel 10 and the second air channel 20 are separated, air flows in the two air channels independently circulate, and when the guide plate 43 rotates to a second position, the communicating part 30 is conducted, so that the first air channel 10 and the second air channel 20 are communicated, and the air flows circulate between the first air channel 10 and the second air channel 20. With this embodiment, the air flow adjusting assembly 40 can adjust the acting states of the first air duct 10 and the second air duct 20 by rotating, thereby realizing the change of the air supply effect of the air conditioner.

Alternatively, the shaft 41 extends along an edge of the baffle 43. Thus, when the rotation shaft 41 rotates, the baffle 43 can open or close the communication portion 30. The rotating shafts 41 are arranged at the edges of different positions of the guide plates 43, so that different rotating effects of the guide plates 43 can be realized. When the deflector 43 rotates to the vertical position, the communicating portion 30 is covered, and when the deflector rotates to the inclined position, a drainage effect can be formed in the first air duct 10 or the second air duct 20, and by adjusting the inclined direction of the deflector 43, air flow can be selectively introduced into the second air duct 20 from the first air duct 10 or the first air duct 10 from the second air duct 20. Alternatively, the rotating shaft 41 passes through the middle part or the position near the edge part of the guide plate 43 and is attached to the plate surface. In this way, the flow guiding plate 43 can also realize the drainage and communication effects when rotating to the second position. Optionally, the motor 42 is provided outside the second air duct 20. Avoiding the motor 42 from affecting the airflow in the second duct 20.

Alternatively, the first position is a position covering the communication portion 30, so that the baffle 43 can block the communication portion 30. Alternatively, the shape of the baffle 43 is adapted to the shape of the communication portion 30. In this way, the communication portion 30 does not interfere with the rotation of the baffle 43 in space, and when the baffle 43 rotates to the first position, the communication portion 30 can be covered to form a seal.

Alternatively, the second position is a position perpendicular to the side wall of the second wind tunnel 20 or a position inclined with respect to the side wall of the second wind tunnel 20. Alternatively, when the baffle 43 is perpendicular to the side wall of the second air duct 20, the baffle 43 blocks the second air duct 20. By designing the area of the deflector 43, when the deflector 43 is perpendicular to the side wall of the second air duct 20, the second air duct 20 is blocked, so that the air flow in the second air duct 20 can completely enter the first air duct 10, and when the air flow is conveyed by the first air duct 10, the air flow in the first air duct 10 can be furthest promoted.

In some embodiments, as shown in connection with fig. 4, the surface of the housing 1 is provided with a first air outlet 11 and a second air outlet 21, the first air outlet 11 is in communication with the first air duct 10, and the second air outlet 21 is in communication with the second air duct 20.

The air flow conveyed by the first air duct 10 flows out of the shell 1 through the first air outlet 11, and the air flow conveyed by the second air duct 20 flows out of the shell 1 through the second air outlet 21. In this embodiment, each air duct has its own air outlet, so that the air conditioner can supply air through different air outlets. By setting the position of the air outlet, the air conditioner can have different air supply directions. Alternatively, the first air outlet 11 is rectangular. Alternatively, the second air outlet 21 is circular. The first air outlet 11 and the second air outlet 21 have different shapes, and different air supply devices may be respectively disposed in the first air duct 10 and the second air duct 20, for example, a through-flow fan is disposed in the first air duct 10, and the second air duct 20 is communicated with a centrifugal fan. Alternatively, the first air outlet 11 has a larger area than the second air outlet 21. The through-flow fan is longer, and the air current that produces is fit for flowing out from first air outlet 11, and centrifugal fan's amount of wind is less, and the wind pressure is great, is fit for flowing out from second air outlet 21.

In some embodiments, the first air outlet 11 and the second air outlet 21 are disposed on the same side of the housing 1. In this way, the air conditioner can be enabled to perform air outlet through the first air outlet 11 and the second air outlet 21 at the side, the position of the air outlet can be more compact, the air conditioner can be conveniently placed in a room, and the side faces the indoor user activity area to air. In some embodiments, the first air outlet 11 is different from the second air outlet 21 in height. In this way, the first air outlet 11 and the second air outlet 21 can be made to perform air-out at different heights. Optionally, the second air outlet 21 has a height greater than the first air outlet 11. When a centrifugal fan is adopted in the second air duct 20, the position of the second air outlet 21 can be arranged above the first air outlet 11, so that the air flow with stronger wind force can be conveyed to a more distant position. Optionally, the second air outlet 21 is provided with a cover plate. The second air outlet 21 can be opened and closed through the cover plate, so that impurities such as dust and the like are prevented from falling into the second air outlet 21 to pollute the internal environment of the air conditioner when the air conditioner does not operate.

In some embodiments, as shown in connection with fig. 3, the housing 1 further comprises a first fan 13 and a second fan 23. The first fan 13 is arranged in the first air duct 10 or the exhaust port is communicated with the first air duct 10 and communicated with the first air duct 10, and the second fan 23 is arranged in the second air duct 20 or the exhaust port is communicated with the second air duct 20. The first fan 13 rotates to generate air flow to be sent to the first air duct 10, and the second fan 23 rotates to generate air flow to be sent to the second air duct 20. The fan is arranged in the air duct, or the exhaust port is communicated with the air duct, so that air supply to the air duct can be realized. In use, only the first fan 13 or the second fan 23 may be turned on, or the first fan 23 and the second fan 23 may be turned on simultaneously to supply air. By this embodiment, two kinds of air flows having different effects can be formed inside the air conditioner, and different air blowing effects are generated from the first air outlet 11 and the second air outlet 21. In combination with the airflow adjusting assembly 40 in the foregoing embodiment, part or all of the airflow in the second air duct 20 may be sent into the first air duct 10, so that the air volume and the air pressure of the first air outlet 11 are larger, the air supply distance is longer, or part of the airflow in the first air duct 10 may be sent into the second air duct 20, so that the air volume of the second air outlet 21 is larger.

Optionally, as shown in fig. 4, the casing 1 is provided with a first air inlet 12 communicated with the first air duct 10, and the first air inlet 12 is opposite to the first air outlet 11. Optionally, the first air inlet 12 is provided with an air intake grill. The first air inlet 12 is opposite to the first air outlet 11, that is, the first air outlet 11 is disposed at the front side of the housing 1, and the first air inlet 12 is disposed at the rear side of the housing 1. When the first fan 13 rotates, the air flow enters from the first air inlet 12, passes through the first air duct 10 and flows to the first air outlet 11. Optionally, a second air inlet 22 is provided at the lower part of the housing 1 and is in communication with the second air duct 20. When the second fan 23 rotates, the air flow enters the second fan 23 from the second air inlet 22 at the lower part of the casing 1, and then enters the second air duct 20.

Optionally, the first fan 13 is a cross-flow fan. The cross flow fan rotates in the first air duct 10, so that the air conditioner can supply air in a long distance. Alternatively, the second fan 23 is a centrifugal fan. The centrifugal fan has larger wind pressure and can generate stronger air flow. Alternatively, the second fan 23 is an axial flow fan. The axial flow fan has a larger flow than the centrifugal fan and occupies a smaller volume than the centrifugal fan, and may also supply air to the second air duct 20.

Optionally, as shown in fig. 5, the second air outlet 21 is disposed on the front side of the housing 1, the air guiding port 14 is disposed on the back side of the housing 1, and when the air flow in the second air duct 20 flows out from the second air outlet 21, the air guiding port 14 can enable the air from the outside to enter, and form a mixed air flow together with the air flow in the second air duct 20, and then flow out from the second air outlet 21 together, so as to increase the air volume. Optionally, the air intake 14 is provided with a cover plate that can be opened and closed. When the cover plate is opened, the second air outlet 21 can send out mixed air flow, and when the cover plate is closed, the second air outlet 21 can send out air flow in the second air duct 20. By simultaneously controlling or individually turning on the first fan 13 and the second fan 23, a plurality of modes of remote air supply/rapid cooling/mixed air supply of the air conditioner can be realized. For example, the axial flow fan is independently turned on to realize remote air supply (the air inlet 14 is closed)/mixed air supply (the air inlet 14 is opened), the through flow fan is independently turned on to realize rapid cooling, the axial flow fan and the through flow fan are simultaneously turned on to realize remote air supply (the air inlet 14 is closed) and rapid cooling, and the axial flow fan and the through flow fan are simultaneously turned on to realize mixed air supply (the air inlet 14 is opened) and rapid cooling.

In some embodiments, as shown in connection with fig. 3, the housing 1 further comprises a heat exchanger 50 therein. The heat exchanger 50 includes a first heat exchanging portion 51 and a second heat exchanging portion 52 connected to each other, the first heat exchanging portion 51 being disposed in the first air duct 10, and the second heat exchanging portion 52 being disposed in the second air duct 20. The first heat exchange portion 51 and the second heat exchange portion 52 of the heat exchanger 50 are connected, the first heat exchange portion 51 is in the first air duct 10, when the air flow passes through, the temperature of the air flow is adjusted, the second heat exchange portion 52 is in the second air duct 20, and similarly, the temperature of the air flow in the second air duct 20 is adjusted. Alternatively, the first heat exchanging portion 51 and the second heat exchanging portion 52 are of an integral structure. Optionally, the second heat exchanging portion 52 is bent with respect to the first heat exchanging portion 51. The refrigerant flows through the first heat exchange portion 51 and the second heat exchange portion 52, and exchanges heat with the air flow in the first air duct 10 and the second air duct 20. Alternatively, the included angle between the first heat exchanging portion 51 and the second heat exchanging portion 52 is alpha, and alpha is 90 degrees less than or equal to alpha <180 degrees. Within this angular range, the heat exchanger 50 is easy to produce and has high utilization efficiency. With this embodiment, the first air duct 10 and the second air duct 20 of the air conditioner can share one heat exchanger 50 for exchanging heat for the respective air flows inside.

In some embodiments, the first air outlet 11 is disposed on the front side of the housing 1 and corresponds to the cross flow fan, the first heat exchange portion 51 is disposed parallel to the cross flow fan, and the first air inlet 12 is disposed on the back side of the housing 1. In this way, the air flow enters from the first air inlet 12, flows through the first heat exchange part 51, has a larger action area with the first heat exchange part 51, can exchange heat better, and then flows out from the first air outlet 11 under the driving of the cross-flow fan. Optionally, the second heat exchange portion 52 is bent relative to the first heat exchange portion 51 and extends into the second air duct 20.

Optionally, the second air duct 20 extends below the second heat exchanging portion 52. The air flow passes through the second heat exchange portion 52 after passing through the outlet of the second air duct 20, and after heat exchange, the air flow can flow in the direction of the second air outlet 21, and then the air is discharged from the second air outlet 21.

In some embodiments, the first air chute 10 and the second air chute 20 extend longitudinally. In this way, the first duct 10 and the second duct 20 can be applied to a cabinet air conditioner. In some embodiments, the width of the second wind tunnel 20 gradually decreases from the discharge opening of the second wind tunnel 20 toward the inlet. When the second fan 23 is a centrifugal fan or an axial fan, the inlet of the second air duct 20 is communicated with the fan, and the width is smaller, so that the effect of enhancing the wind pressure can be achieved. In addition, when the first air inlet 12 is disposed on the back side of the housing 1, the second air duct 20 may block some of the incoming air flow, and if the width of the second air duct 20 is gradually reduced, the blocking of the air flow entering through the first air inlet 12 can be reduced at the narrower portion of the second air duct 20.

As shown in connection with fig. 6, an embodiment of the present disclosure provides a base including a housing 60 and a plurality of flow directing members 70. The outer cover 60 is provided with an air outlet portion 62 and a plurality of air inlet portions 61, and forms a gas circulation space therein, and a plurality of flow guide members 70 provided between the air inlet portions 61 and the air outlet portions 62 for guiding the air flow entering the circulation space so that the air flow uniformly flows out from the air outlet portions 62.

The base has a housing 60, and a circulation space for air is formed inside the housing 60, and air flows into the circulation space from a plurality of air inlet portions 61 of the housing 60 and then flows out from an air outlet portion 62. The air flows entering from the plurality of air inlet portions 61 are not uniform enough when they flow out from the air outlet portion 62 after interaction. When the base is applied to a cabinet air conditioner, air flows into the air conditioner through the air outlet part 62, so that noise is easy to generate, and the air outlet effect of the air conditioner is also affected. In the application, the flow guide members 70 are arranged in the circulation space, the flow guide members 70 are positioned between the air inlet part 61 and the air outlet part 62, and when the air flow passes through the circulation space, the air flow is guided by the plurality of flow guide members 70, and the air flow becomes more uniform after being guided and split. Optionally, the air outlet 62 of the base communicates with an air supply device. By the operation of the air blowing device, outside air is introduced into the chassis from the air inlet portion 61, and then flows from the air outlet portion 62 to the air blowing device. The air supply device may be a centrifugal fan or an axial fan. With this embodiment, the base can make the air flow entering the interior to form a relatively uniform air flow to be sent out from the air outlet 62.

Optionally, the outer cover 60 is a shell surrounded by a plate structure, and the air inlet portion 61 is opened on the surface of the outer cover 60. Optionally, the outer cover 60 is a frame, and the air flow can enter and exit from the hollow part of the frame, and the frame also has a supporting function and can support the structure above the base. Alternatively, the outer cover 60 is a frame with a truncated cone shape, the outer periphery of the outer cover 60 forms a plurality of air inlet portions 61, and the top of the outer cover 60 is an air outlet portion 62. In this way, when the upper portion of the housing 60 communicates with the air blowing device or with the duct in which the air blowing device is located, air flow can be caused to enter from around the base, and flow from the top of the base to the air blowing device or the duct in which the air blowing device is located.

In some embodiments, as shown in connection with fig. 7, the flow directing member 70 is hollow and tubular and is provided with an inlet 71 and an outlet 72. The hollow tubular flow guide member 70 allows part of the external air to flow along the inside of the flow guide member 70 after entering from the inlet 71 and to flow out from the outlet 72, and the flow direction of the air flow is adjusted after passing through the flow inside the flow guide member 70. Part of the external air flow does not enter the flow guiding member 70, but after striking the outer side wall of the flow guiding member 70, changes the flow direction, and forms a new flow direction along the guidance of the outer side wall.

In some embodiments, the outlet 72 is directed toward the air outlet 62. In this way, the air flow flowing out of the guide member 70 can flow toward the air outlet 62, and can be mixed with the air flow not entering the guide member 70, and can flow toward the air outlet 62. In some embodiments, the outlet 72 is provided at one end of the flow directing member 70 and the inlet 71 is provided at a side wall of the flow directing member 70. One end of the flow guide member 70 faces the air outlet 62, and the air flow is easily directed to the air outlet 62 after exiting from the outlet 72. The inlet 71 is provided on a side wall of the flow guiding member 70, and after the airflow hits the side wall of the flow guiding member 70, part of the airflow can enter the flow guiding member 70 through the inlet 71. Optionally, the inlet 71 is multiple. The air flow is able to enter the interior of the flow directing member 70 from a plurality of inlets 71. Optionally, the other end of the flow guide member 70 is provided at the bottom of the housing 60. In this way, the fixation of the flow guiding member 70 is facilitated. Optionally, the other end of the flow directing member 70 is open for air intake. Thus, the air flow can also flow into the guide member 70 from the other end of the guide member 70.

In some embodiments, the length of the flow directing member 70 is inversely proportional to the distance of the flow directing member 70 from the air outlet 62. That is, the shorter the length of the flow guide member 70 is, the longer the flow guide member 70 is, the closer the flow guide member 70 is to the air outlet 62. Optionally, the air outlet 62 is provided in the top center of the outer cover 60. After entering the air inlet part 61 at the periphery of the base, the air flows towards the center of the top, and the guide part 70 which is nearer to the air outlet part 62 has longer length, so that the air can be guided to the air outlet part 62. In the truncated cone-shaped base, the length of the flow guide member 70 is shorter as it is farther from the air outlet 62, so that collision with the top of the base can be avoided.

In some embodiments, the pipe diameter of the flow directing member 70 is proportional to the distance of the flow directing member 70 from the air outlet 62. The diameter of the flow guiding component 70 far from the air outlet 62 is larger, so that more air flows enter the flow guiding component 70, and the distribution and guiding effects on the air flows just entering the base are stronger. The pipe diameter of the flow guiding component 70 closer to the air outlet 62 is smaller, so that partial air flow is slightly regulated again when the partial air flow passes through the flow guiding component 70 closer to the air outlet 62 after being guided by the flow guiding component 70 with the pipe diameter.

In some embodiments, as shown in connection with fig. 6, the plurality of flow guiding members 70 are radially distributed with the radiation center facing the air outlet 62. The plurality of flow guiding members 70 are radially distributed, and the radiation center faces the air outlet portion 62, so that when the air flows through the flow guiding members 70, the air flow tends to flow along the radiation arrays of the plurality of flow guiding members 70 to the radiation center as a whole, and the air flow is facilitated to flow to the air outlet portion 62. For the base of the outer cover 60 with a truncated cone shape, the plurality of flow guiding members 70 are radially distributed and are matched with the shape of the outer cover 60.

In some embodiments, the flow directing members 70 are provided on the side walls of the housing 60. The flow guide 70 is secured to a sidewall of the housing 60, which may be a bottom sidewall of the housing 60. When the air outlet 62 is provided at the top of the housing 60, the flow guide 70 extends from the bottom sidewall of the housing 60 to the top so that the air flow is guided and distributed into the air outlet 62. Alternatively, the air inlet portions 61 are provided on the outer periphery of the housing 60, the air outlet portions 62 are provided on the top of the housing 60, and the flow guide member 70 is provided on the bottom side wall of the housing 60. In this way, when the air flows from the plurality of air inlet portions 61 on the outer periphery of the housing 60 into the circulation space and passes through the guide members 70, a part of the air flows between the guide members 70, a part of the air flows inside the guide members 70, and the mixed air flows to form a relatively uniform air flow and flows out of the air outlet portion 62.

In some embodiments, the housing 60 is frustoconical. The truncated cone-shaped housing 60 is more stable in supporting the base and is adapted to allow air flow to enter from the plurality of inlets 71 at the periphery of the housing 60 and to be supplied upwardly. Optionally, the housing 60 is rectangular parallelepiped. The rectangular parallelepiped housing 60 also provides support for the base and for the airflow therethrough.

Optionally, a base is provided at a lower portion of the housing 60, and an air inlet is provided at the base, and an air flow space is formed inside and communicates with the circulation space. In this way, the air flow can also enter from the air inlet portion 61 of the base, and enter from the bottom of the circulation space through the air flow space.

The embodiment of the disclosure also provides a cabinet air conditioner, which is shown in fig. 8, and includes the base provided by any one of the foregoing embodiments. The cabinet air conditioner can be used for air inlet from the side face and/or the bottom face of the base through the base, and guiding and distributing air flow, so that the air flow entering the cabinet air conditioner is uniform, and the air outlet of the cabinet air conditioner is closer to natural air.

In some embodiments, as shown in connection with fig. 1, the cabinet air conditioner includes a housing 1, a first air duct 10 and a second air duct 20 are included in the housing 1, the second air duct 20 is provided with a centrifugal fan or an axial fan, and an air outlet portion 62 of the base is communicated with the second air duct 20. The centrifugal fan or the axial fan drives the air flow to enter from the base and blow through the second air duct 20, so that the air blowing effect is more natural. In addition, the base can increase the air flow in the second air duct 20, and if the air flow adjusting assembly 40 is combined, the air flow in the second air duct 20 can be split into the first air duct 10, and the air outlet effect of the first air duct 10 can be adjusted.

The above description and the drawings illustrate embodiments of the disclosure sufficiently to enable those skilled in the art to practice them. Other embodiments may include structural and other modifications. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in, or substituted for, those of others. The embodiments of the present disclosure are not limited to the structures that have been described above and shown in the drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
