[0027] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments may be combined with each other.

[0028] Combined with Figure 1-3 As shown, an embodiment of the present disclosure provides an air conditioner, including a housing 1, and the housing 1 includes: a first air duct 10, a second air duct 20, and a connecting portion 30. Among them, the second air duct 20 passes through the first air duct 10; the connecting portion 30 is disposed on the side wall of the second air duct 20 and is configured to connect the first air duct 10 and the second air duct 20; the air flow regulating assembly 40 is rotatably disposed on the connecting portion 30 and is configured to block the connecting portion 30 to separate the first air duct 10 and the second air duct 20 when rotated to the first position, and conduct the connecting portion 30 to connect the first air duct 10 and the second air duct 20 when rotated to the second position.

[0029] The air flow can flow in the first air duct 10 or in the second air duct 20. The second air duct 20 passes through the first air duct 10, which can make the space occupied by the air ducts more compact and facilitate the external shape design of the housing 1. The connecting portion 30 is disposed on the side wall of the second air duct 20, which can connect the first air duct 10 and the second air duct 20, so that the air flow can flow between the first air duct 10 and the second air duct 20. The air flow regulating assembly 40 is disposed on the connecting portion 30 and can rotate relative to the connecting portion 30. When the air flow regulating assembly 40 rotates to the first position, it blocks the connecting portion 30 to separate the first air duct 10 and the second air duct 20; when rotated to the second position, it conducts the connecting portion 30 to connect the first air duct 10 and the second air duct 20. In the state where the first air duct 10 and the second air duct 20 are separated, the air flow flows in the first air duct 10 and the second air duct 20 respectively without affecting each other. In the state where the first air duct 10 and the second air duct 20 are connected, the air flow 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 flow in the first air duct 10 and the second air duct 20 can be adjusted.

[0030] Through this embodiment, the air conditioner can deliver air flow through the first air duct 10 and the second air duct 20 respectively, and the state of connection and separation between the first air duct 10 and the second air duct 20 can be adjusted. By adjusting the state, the air supply effect of the first air duct 10 and the second air duct 20 is no longer fixed, but can change.

[0031] Optionally, the connecting part 30 is an opening on the side wall of the second air duct 20. The side wall of the second air duct 20 is provided with an opening to achieve the connection between the first air duct 10 and the second air duct 20. Optionally, the shape of the opening is circular, oval, rectangular or trapezoidal. Through the openings of the above shapes, the connection between the first and second air ducts 20 can be achieved. Optionally, the cross-section of the second air duct 20 is circular, oval, rectangular or trapezoidal. The second air duct 20 with a circular, oval or rectangular cross-section can enable the air flow to pass through smoothly. The cross-sectional shape of the second air duct 20 can be selected according to the distribution of the internal components of the housing to avoid spatial interference with other internal components. When the cross-section is rectangular, the side wall of the second air duct 20 is a plane, which can be closer to the heat exchanger 50 in the air conditioner, facilitating the adjustment of the air flow temperature by using the heat or cold released by the heat exchanger 50. When the cross-section is rectangular, it is also convenient to connect the second air duct 20 with the air outlet of the centrifugal fan.

[0032] In some embodiments, as shown in combination with Figure 2 the air flow regulating assembly 40 includes: a rotating shaft 41, a motor 42 and a guide vane 43. The rotating shaft 41 is rotatably arranged in the connecting part 30; the motor 42 is connected to the rotating shaft 41 to drive the rotating shaft 41 to rotate; the guide vane 43 is fixedly connected to the rotating shaft 41 and is configured to block the connecting part 30 when rotating to the first position and conduct the connecting part 30 when rotating to the second position.

[0033] The motor 42 drives the rotating shaft 41 to rotate, and then drives the guide vane 43 to rotate. When the guide vane 43 rotates to the first position, it blocks the connecting part 30 to separate the first air duct 10 and the second air duct 20, so that the air flows in the two air ducts independently. When the guide vane 43 rotates to the second position, it conducts the connecting part 30 to connect the first air duct 10 and the second air duct 20, and the air flows between the first air duct 10 and the second air duct 20. Through this embodiment, the air flow regulating assembly 40 can adjust the working state of the first air duct 10 and the second air duct 20 by rotation, realizing the change of the air supply effect of the air conditioner.

[0034] Optionally, the rotating shaft 41 extends along the edge of the deflector 43. In this way, when the rotating shaft 41 rotates, the deflector 43 can open or cover the communication part 30. By selecting the edge of different positions of the deflector 43 to set the rotating shaft 41, different rotating effects of the deflector 43 can be achieved. When the deflector 43 rotates to the vertical position, it covers the communication part 30. When it rotates to the inclined position, it can form a guiding effect in the first air duct 10 or the second air duct 20. By adjusting the inclination direction of the deflector 43, it is possible to select to introduce the air flow from the first air duct 10 into the second air duct 20 or from the second air duct 20 into the first air duct 10. Optionally, the rotating shaft 41 passes through the middle or a position near the edge of the deflector 43 and fits with the plate surface. In this way, when the deflector 43 rotates to the second position, the effects of guiding and communicating can also be achieved. Optionally, the motor 42 is arranged outside the second air duct 20 to avoid the motor 42 affecting the air flow in the second air duct 20.

[0035] Optionally, the first position is the position covering the communication part 30. In this way, the deflector 43 can block the communication part 30. Optionally, the shape of the deflector 43 matches the shape of the communication part 30. In this way, the communication part 30 will not cause spatial interference to the rotation of the deflector 43, and when the deflector 43 rotates to the first position, it can cover the communication part 30 to form a seal.

[0036] Optionally, the second position is the position perpendicular to the side wall of the second air duct 20 or the position inclined relative to the side wall of the second air duct 20. Optionally, when the deflector 43 is perpendicular to the side wall of the second air duct 20, the deflector 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, it blocks the second air duct 20. In this way, the air flow in the second air duct 20 can completely enter the first air duct 10. When only the first air duct 10 needs to convey the air flow, the air flow rate in the first air duct 10 can be maximally increased.

[0037] In some embodiments, as shown in Figure 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 communicated with the first air duct 10, and the second air outlet 21 is communicated with the second air duct 20.

[0038] The air flow conveyed by the first air duct 10 flows out of the housing 1 through the first air outlet 11, and the air flow conveyed by the second air duct 20 flows out of the housing 1 through the second air outlet 21. In this embodiment, each air duct has its own air outlet for air discharge, enabling the air conditioner to supply air through different air outlets. By setting the positions of the air outlets, the air conditioner can have different air supply directions. Optionally, the first air outlet 11 is rectangular. Optionally, the second air outlet 21 is circular. Since the first air outlet 11 and the second air outlet 21 have different shapes, different air supply devices can be arranged in the first air duct 10 and the second air duct 20 respectively. For example, a cross-flow fan is arranged in the first air duct 10, and the second air duct 20 is connected to a centrifugal fan. Optionally, the area of the first air outlet 11 is larger than that of the second air outlet 21. Due to its longer length, the cross-flow fan generates an air flow suitable for flowing out of the first air outlet 11. The centrifugal fan has a smaller air volume and a larger air pressure, which is suitable for flowing out of the second air outlet 21.

[0039] In some embodiments, the first air outlet 11 and the second air outlet 21 are arranged on the same side of the housing 1. In this way, the air conditioner can discharge air through the first air outlet 11 and the second air outlet 21 on this side, making the positions of the air outlets more compact, facilitating the placement of the air conditioner in the room, and enabling the air to be discharged towards the indoor user activity area on this side. In some embodiments, the heights of the first air outlet 11 and the second air outlet 21 are different. In this way, the first air outlet 11 and the second air outlet 21 can discharge air at different heights. Optionally, the height of the second air outlet 21 is greater than that of the first air outlet 11. When a centrifugal fan is used in the second air duct 20, the position of the second air outlet 21 can be set above the first air outlet 11, so that the air flow with stronger wind force can be conveyed to a farther 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. When the air conditioner is not running, dust and other debris can be prevented from falling into the second air outlet 21, thus polluting the internal environment of the air conditioner.

[0040] In some embodiments, in combination with Figure 3As shown, the housing 1 further includes a first fan 13 and a second fan 23. The first fan 13 is disposed in the first air duct 10, or the exhaust port communicates with the first air duct 10; the second fan 23 is disposed in the second air duct 20, or the exhaust port communicates with the second air duct 20. The first fan 13 rotates to generate an air flow and send it into the first air duct 10, and the second fan 23 rotates to generate an air flow and send it into the second air duct 20. Whether the fan is disposed in the air duct or the exhaust port communicates with the air duct, air can be sent into the air duct. During use, only the first fan 13 or the second fan 23 can be turned on, or the first and second fans 23 can be turned on simultaneously for air supply. Through this embodiment, two different air flows with different effects can be formed inside the air conditioner, and different air supply effects can be generated from the first air outlet 11 and the second air outlet 21. Combining with the air flow regulating component 40 in the foregoing embodiment, part or all of the air flow in the second air duct 20 can be sent into the first air duct 10, so that the air volume and air pressure at the first air outlet 11 are greater and the air supply distance is longer, or part of the air flow in the first air duct 10 can be sent into the second air duct 20, so that the air volume at the second air outlet 21 is greater.

[0041] Optionally, in combination with Figure 4 As shown, the housing 1 is provided with a first air inlet 12 communicating with the first air duct 10, and the first air inlet 12 is opposite to the first air outlet 11 in position. Optionally, the first air inlet 12 is provided with an air inlet grille. The first air inlet 12 is opposite to the first air outlet 11 in position, that is, if the first air outlet 11 is disposed on the front side of the housing 1, then the first air inlet 12 is disposed on 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 then flows to the first air outlet 11. Optionally, the lower part of the housing 1 is provided with a second air inlet 22 communicating 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 housing 1, and then enters the second air duct 20.

[0042] Optionally, the first fan 13 is a cross-flow fan. The cross-flow fan rotates in the first air duct 10, which can enable the air conditioner to supply air over a long distance. Optionally, the second fan 23 is a centrifugal fan. The centrifugal fan has a greater air pressure and can generate a stronger air flow. Optionally, the second fan 23 is an axial-flow fan. The axial-flow fan has a larger flow rate than the centrifugal fan, and generally occupies a smaller volume than the centrifugal fan, and can also supply air to the second air duct 20.

[0043] Optionally, in combination with Figure 5As shown in the figure, the second air outlet 21 is provided on the front side of the housing 1, and an air intake port 14 is provided on the back side of the housing 1. When the air flow in the second air duct 20 flows out from the second air outlet 21, the air intake port 14 can allow external air to enter, forming a mixed air flow with the air flow in the second air duct 20, and the two flow out from the second air outlet 21 together, increasing the air volume. Optionally, the air intake port 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 the mixed air flow. When the cover plate is closed, the second air outlet 21 can send out the air flow in the second air duct 20. By simultaneously controlling or separately turning on the first fan 13 and the second fan 23, multiple modes of long-distance air supply / rapid cooling / mixed air supply of the air conditioner can be realized. For example, when the axial flow fan is turned on alone, long-distance air supply (the air intake port 14 is closed) / mixed air supply (the air intake port 14 is opened) can be realized; when the cross-flow fan is turned on alone, rapid cooling can be realized; when the axial flow fan and the cross-flow fan are turned on simultaneously, long-distance air supply (the air intake port 14 is closed) and rapid cooling can be realized; when the axial flow fan and the cross-flow fan are turned on simultaneously, mixed air supply (the air intake port 14 is opened) and rapid cooling can be realized.

[0044] In some embodiments, in combination with Figure 3 As shown in the figure, the housing 1 further includes a heat exchanger 50. The heat exchanger 50 includes a first heat exchange part 51 and a second heat exchange part 52 that are connected to each other. The first heat exchange part 51 is provided in the first air duct 10, and the second heat exchange part 52 is provided in the second air duct 20. The first heat exchange part 51 and the second heat exchange part 52 of the heat exchanger 50 are connected. The first heat exchange part 51 is in the first air duct 10, so that when the air flow passes through, the temperature of the air flow is adjusted. Similarly, the second heat exchange part 52 is in the second air duct 20, and the temperature of the air flow in the second air duct 20 is adjusted. Optionally, the first heat exchange part 51 and the second heat exchange part 52 are of an integral structure. Optionally, the second heat exchange part 52 is bent relative to the first heat exchange part 51. The refrigerant flows through the first heat exchange part 51 and the second heat exchange part 52, and heat exchange occurs with the air flow in the first air duct 10 and the second air duct 20. Optionally, the included angle between the first heat exchange part 51 and the second heat exchange part 52 is α, and 90°≤α<180°. Within this angle range, the heat exchanger 50 is easy to produce and has high utilization efficiency. Through this embodiment, the first air duct 10 and the second air duct 20 of the air conditioner can share a heat exchanger 50 to exchange heat for the air flow inside them respectively.

[0045] In some embodiments, the first air outlet 11 is provided on the front side of the housing 1 and corresponds to the cross-flow fan. The first heat exchange part 51 is arranged parallel to the cross-flow fan, and the first air inlet 12 is provided 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, and has a larger acting area with the first heat exchange part 51, enabling better heat exchange. Then, driven by the cross-flow fan, it flows out from the first air outlet 11. Optionally, the second heat exchange part 52 is bent relative to the first heat exchange part 51 and extends into the second air duct 20.

[0046] Optionally, the second air duct 20 extends below the second heat exchange part 52. After the air flow passes through the air outlet of the second air duct 20, it flows through the second heat exchange part 52, and after heat exchange, it can also flow towards the direction of the second air outlet 21, and then blows out from the second air outlet 21.

[0047] In some embodiments, the first air duct 10 and the second air duct 20 extend longitudinally. In this way, the first air duct 10 and the second air duct 20 can be applied to an air-conditioning cabinet. In some embodiments, the width of the second air duct 20 gradually decreases from the air outlet to the inlet of the second air duct 20. When the second fan 23 is a centrifugal fan or an axial flow fan, the inlet of the second air duct 20 is communicated with the fan, and the width is small, which can play a role in enhancing the air pressure. And when the first air inlet 12 is arranged on the back side of the housing 1, the incoming air flow may be blocked by the second air duct 20 to some extent. If the width of the second air duct 20 gradually decreases, at the narrower part of the second air duct 20, the blockage of the air flow entering from the first air inlet 12 can be reduced.

[0048] Combined Figure 6 As shown, an embodiment of the present disclosure provides a base, including an outer cover 60 and a plurality of flow guiding components 70. The outer cover 60 is provided with an air outlet part 62 and a plurality of air inlet parts 61, and a gas circulation space is formed inside; the plurality of flow guiding components 70 are arranged between the air inlet part 61 and the air outlet part 62 to guide the air flow entering the circulation space so that the air flow flows out evenly from the air outlet part 62.

[0049] The base has an outer cover 60, and a gas circulation space is formed inside by the wrapping of the outer cover 60. The air flow enters the circulation space from the plurality of air inlet parts 61 of the outer cover 60 and then flows out from the air outlet part 62. The air flow entering from the plurality of air inlet parts 61 is not uniform enough when flowing out from the air outlet part 62 after interaction. When the base is applied to an air-conditioning cabinet, the air flow flows into the air conditioner through the air outlet part 62, which is not only likely to generate noise, but also affects the air supply effect of the air conditioner. In this application, flow guiding components 70 are arranged in the circulation space. The flow guiding components 70 are located between the air inlet part 61 and the air outlet part 62. When the air flow passes through the circulation space, the plurality of flow guiding components 70 guide the air flow. After being guided and split, the air flow becomes more uniform. Optionally, the air outlet part 62 of the base is communicated with the air supply device. Through the operation of the air supply device, external air enters the base from the air inlet part 61 and then flows from the air outlet part 62 to the air supply device. The air supply device can be a centrifugal fan or an axial flow fan. Through this embodiment, the base can make the air flow entering the interior form a relatively uniform air flow and send it out from the air outlet part 62.

[0050] Optionally, the outer cover 60 is a housing surrounded by a plate-like structure, and the air inlet portion 61 is provided on the surface of the outer cover 60. Optionally, the outer cover 60 is a frame, and air can enter and exit through the hollowed-out portion of the frame. Moreover, the frame also has a supporting function and can support the structure above the base. Optionally, the outer cover 60 is a frustum-shaped frame, and a plurality of air inlet portions 61 are formed on the outer periphery of the outer cover 60, and the top of the outer cover 60 is the air outlet portion 62. In this way, when the upper part of the outer cover 60 is connected to the air supply device or the air duct where the air supply device is located, air can enter from the periphery of the base and flow from the top of the base to the air supply device or the channel where the air supply device is located.

[0051] In some embodiments, as shown in Figure 7 the flow guiding component 70 is in a hollow tubular shape and is provided with an inlet 71 and an outlet 72. The hollow tubular flow guiding component 70 can enable some external air to enter from the inlet 71, flow along the inside of the flow guiding component 70, and flow out from the outlet 72. After flowing inside the flow guiding component 70, the flow direction of the air flow is adjusted. Some external air flow does not enter the flow guiding component 70, but after hitting the outer side wall of the flow guiding component 70, it changes the flow direction and forms a new flow direction along the guiding of the outer side wall.

[0052] In some embodiments, the outlet 72 faces the air outlet portion 62. In this way, the air flow flowing out from the flow guiding component 70 can flow towards the air outlet portion 62, mix with the air flow that does not enter the flow guiding component 70, and jointly flow towards the air outlet portion 62. In some embodiments, the outlet 72 is provided at one end of the flow guiding component 70, and the inlet 71 is provided on the side wall of the flow guiding component 70. One end of the flow guiding component 70 faces the air outlet portion 62, and it is easy for the air flow to flow towards the air outlet portion 62 after flowing out from the outlet 72. The inlet 71 is provided on the side wall of the flow guiding component 70. After the air flow hits the side wall of the flow guiding component 70, some of the air flow can enter the flow guiding component 70 through the inlet 71. Optionally, there are a plurality of inlets 71. The air flow can enter the inside of the flow guiding component 70 from the plurality of inlets 71. Optionally, the other end of the flow guiding component 70 is provided at the bottom of the outer cover 60. In this way, it is convenient to fix the flow guiding component 70. Optionally, the other end of the flow guiding component 70 is an open end for air inlet. In this way, the air flow can also flow into the inside of the flow guiding component 70 from the other end of the flow guiding component 70.

[0053] In some embodiments, the length of the flow guiding member 70 is inversely proportional to the distance from the flow guiding member 70 to the air outlet portion 62. That is, the length of the flow guiding member 70 farther away from the air outlet portion 62 is shorter, and the length of the flow guiding member 70 closer to the air outlet portion 62 is longer. Optionally, the air outlet portion 62 is provided at the center of the top of the outer cover 60. After the air flow enters through the air inlet portion 61 on the outer periphery of the base, it flows toward the center of the top. The flow guiding member 70 closer to the air outlet portion 62 has a longer length, which is beneficial for guiding the air flow toward the air outlet portion 62. In the frustum-shaped base, the flow guiding member 70 farther away from the air outlet portion 62 has a shorter length, which can avoid collision with the top of the base.

[0054] In some embodiments, the pipe diameter of the flow guiding member 70 is directly proportional to the distance from the flow guiding member 70 to the air outlet portion 62. The pipe diameter of the flow guiding member 70 farther away from the air outlet portion 62 is larger, so that more air flow enters the flow guiding member 70, and the distribution and guiding effect on the air flow just entering the base is stronger. The pipe diameter of the flow guiding member 70 closer to the air outlet portion 62 is smaller, so that after part of the air flow is guided by the flow guiding member 70 with a certain pipe diameter, when it flows through the flow guiding member 70 closer to the air outlet portion 62, a smaller adjustment is made again.

[0055] In some embodiments, as shown in Figure 6 As shown, a plurality of flow guiding members 70 are radially distributed, and the radiation center faces the air outlet portion 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 flow flows through the flow guiding members 70, as a whole, it tends to flow along the radiation array of the plurality of flow guiding members 70 toward the radiation center, which is beneficial for the air flow to flow toward the air outlet portion 62. For the base with the outer cover 60 in a frustum shape, the plurality of flow guiding members 70 are radially distributed, which matches the shape of the outer cover 60 better.

[0056] In some embodiments, the flow guiding member 70 is provided on the side wall of the outer cover 60. The flow guiding member 70 is fixed to the side wall of the outer cover 60, and the side wall can be the bottom side wall of the outer cover 60. When the air outlet portion 62 is provided at the top of the outer cover 60, the flow guiding member 70 extends from the bottom side wall of the outer cover 60 to the top, so that the air flow is guided and distributed and enters the air outlet portion 62. Optionally, a plurality of air inlet portions 61 are provided on the outer periphery of the outer cover 60, the air outlet portion 62 is provided at the top of the outer cover 60, and the flow guiding member 70 is provided on the bottom side wall of the outer cover 60. In this way, the air flow enters the circulation space from the plurality of air inlet portions 61 on the outer periphery of the outer cover 60. When passing through the flow guiding member 70, part of the air flow flows through between the flow guiding members 70, and part of the air flow flows through the inside of the flow guiding member 70. After mixing, a relatively uniform air flow flows out from the air outlet portion 62.

[0057] In some embodiments, the outer cover 60 is frustum-shaped. The frustum-shaped outer cover 60 facilitates the base to play a supporting role, making it more stable, and is suitable for air to enter from multiple inlets 71 on the outer periphery of the outer cover 60 and blow upward. Optionally, the outer cover 60 is cuboid-shaped. The cuboid-shaped outer cover 60 can also enable the base to have a supporting role and allow air to pass through.

[0058] Optionally, a base is provided at the lower part of the outer cover 60. The base is provided with an air inlet, and an air flow space is formed inside, and the air flow space communicates with the circulation space. In this way, air can also enter from the air inlet part 61 of the base, pass through the air flow space and enter from the bottom of the circulation space.

[0059] The embodiments of the present disclosure also provide an air conditioner cabinet, combined with Figure 8 as shown, including the base provided in any of the foregoing embodiments. By providing this base, the air conditioner cabinet can intake air from the side and / or bottom of the base, guide and distribute the air flow, so that the air flow entering the interior of the air conditioner cabinet is relatively uniform, thereby making the air output of the air conditioner cabinet closer to natural wind.

[0060] In some embodiments, combined with Figure 1 as shown, the air conditioner cabinet includes a housing 1. The housing 1 includes a first air duct 10 and a second air duct 20. The second air duct 20 is provided with a centrifugal fan or an axial flow fan. The air outlet part 62 of the base communicates with the second air duct 20. The centrifugal fan or the axial flow fan drives the air flow to enter from the base, passes through the second air duct 20 for air supply, and the air supply effect is more natural. Moreover, the base can increase the air flow rate in the second air duct 20. If combined with the air flow regulating component 40, the air flow in the second air duct 20 can be split into the first air duct 10 to adjust the air output effect of the first air duct 10.
