[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0029] Combination Figure 6 As shown, the embodiment of the present disclosure provides a base, including an outer cover 60 and a plurality of guide components 70. The outer cover 60 is provided with an air outlet 62 and a plurality of air inlets 61, and a gas circulation space is formed inside; the plurality of guide components 70 are provided between the air inlet 61 and the air outlet 62, and guide the airflow entering the circulation space so that the airflow flows out from the air outlet 62 evenly.

[0030] The base has an outer cover 60, and a gas circulation space is formed by the wrapped interior of the outer cover 60. The airflow enters the circulation space from multiple air inlets 61 of the outer cover 60, and then flows out from the air outlet 62. After the airflow entering from the multiple air inlets 61 interacts with each other, it is not uniform when it flows out from the air outlet 62. When the base is applied to an air-conditioning cabinet, the airflow flows to the inside of the air conditioner through the air outlet 62, which not only easily generates noise, but also affects the air outlet effect of the air conditioner. The present application sets a guide component 70 in the circulation space, and the guide component 70 is located between the air inlet 61 and the air outlet 62. When the airflow passes through the circulation space, multiple guide components 70 guide the airflow, and after guiding and diverting, the airflow becomes more uniform. Optionally, the air outlet 62 of the base is connected to the air supply device. Through the operation of the air supply device, the external air enters the base from the air inlet 61, and then flows from the air outlet 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 airflow entering the interior form a more uniform airflow and be sent out from the air outlet 62.

[0031] Optionally, the outer cover 60 is an outer shell surrounded by a plate-like structure, and the air inlet 61 is opened on the surface of the outer cover 60. Optionally, the outer cover 60 is a frame, and the airflow 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. Optionally, the outer cover 60 is a truncated cone-shaped frame, and a plurality of air inlets 61 are formed on the periphery of the outer cover 60, and the top of the outer cover 60 is an air outlet 62. In this way, when the upper part of the outer cover 60 is connected to the air supply device, or connected to the air duct where the air supply device is located, the airflow can enter from all around 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.

[0032] In some embodiments, in combination Figure 7As shown, the guide component 70 is in a hollow tubular shape and is provided with an inlet 71 and an outlet 72. The hollow tubular guide component 70 can allow part of the external air to enter from the inlet 71, flow along the inside of the guide component 70, and flow out from the outlet 72. After flowing inside the guide component 70, the flow direction of the airflow is adjusted. Part of the external airflow does not enter the guide component 70, but changes its flow direction after hitting the outer wall of the guide component 70, and forms a new flow direction along the outer wall.

[0033] In some embodiments, the outlet 72 faces the air outlet 62. In this way, the airflow flowing out of the guide member 70 can flow toward the air outlet 62, mix with the airflow that has not entered the guide member 70, and flow toward the air outlet 62 together. In some embodiments, the outlet 72 is provided at one end of the guide member 70, and the inlet 71 is provided at the side wall of the guide member 70. One end of the guide member 70 faces the air outlet 62, and the airflow is easy to flow toward the air outlet 62 after flowing out of the outlet 72. The inlet 71 is provided at the side wall of the guide member 70, and after the airflow hits the side wall of the guide member 70, part of the airflow can enter the guide member 70 through the inlet 71. Optionally, there are multiple inlets 71. The airflow can enter the inside of the guide member 70 from multiple inlets 71. Optionally, the other end of the guide member 70 is provided at the bottom of the outer cover 60. In this way, it is convenient to fix the guide member 70. Optionally, the other end of the guide member 70 is open, and the open is used for air intake. In this way, the airflow can also flow into the interior of the air guide component 70 from the other end of the air guide component 70 .

[0034] In some embodiments, the length of the guide component 70 is inversely proportional to the distance from the guide component 70 to the air outlet 62. That is, the farther the guide component 70 is from the air outlet 62, the shorter the length is, and the closer the guide component 70 is to the air outlet 62, the longer the length is. Optionally, the air outlet 62 is arranged at the top center of the outer cover 60. After the airflow enters the air inlet 61 at the periphery of the base, it flows toward the top center, and the guide component 70 closer to the air outlet 62 is longer, which is conducive to guiding the airflow to the air outlet 62. In the truncated cone-shaped base, the guide component 70 farther from the air outlet 62 is shorter, which can avoid collision with the top of the base.

[0035] In some embodiments, the diameter of the guide component 70 is proportional to the distance between the guide component 70 and the air outlet 62. The guide component 70 farther from the air outlet 62 has a larger diameter, so that more air flows into the guide component 70, which has a stronger distribution and guiding effect on the air flow that has just entered the base. The guide component 70 closer to the air outlet 62 has a smaller diameter, so that part of the air flow is guided by the guide component 70 with a larger diameter and then flows through the guide component 70 closer to the air outlet 62, and is adjusted again.

[0036] In some embodiments, in combination Figure 6 As shown, multiple flow guide components 70 are radially distributed, and the radiation center is toward the air outlet 62. Multiple flow guide components 70 are radially distributed, and the radiation center is toward the air outlet 62, so that when the airflow flows through the flow guide components 70, it tends to flow toward the radiation center along the radiation array of the multiple flow guide components 70 as a whole, which is conducive to the airflow flowing to the air outlet 62. For the base of the outer cover 60 in the shape of a truncated cone, multiple flow guide components 70 are radially distributed, which is more compatible with the shape of the outer cover 60.

[0037] In some embodiments, the guide component 70 is disposed on the side wall of the outer cover 60. The guide component 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 62 is disposed at the top of the outer cover 60, the guide component 70 extends from the bottom side wall of the outer cover 60 to the top, so that the airflow is guided and distributed and enters the air outlet 62. Optionally, a plurality of air inlets 61 are disposed on the periphery of the outer cover 60, the air outlet 62 is disposed on the top of the outer cover 60, and the guide component 70 is disposed on the bottom side wall of the outer cover 60. In this way, the airflow enters the circulation space from the plurality of air inlets 61 on the periphery of the outer cover 60. When passing through the guide component 70, part of the airflow flows between the guide components 70, and part of the airflow flows through the inside of the guide component 70. After mixing, a relatively uniform airflow is formed and flows out from the air outlet 62.

[0038] In some embodiments, the outer cover 60 is in a truncated cone shape. The truncated cone-shaped outer cover 60 is easy for the base to play a supporting role, is more stable, and is suitable for airflow to enter from multiple inlets 71 on the outer periphery of the outer cover 60 and send air upward. Optionally, the outer cover 60 is in a rectangular parallelepiped shape. The rectangular parallelepiped outer cover 60 can also make the base have a supporting role and allow airflow to pass through.

[0039] Optionally, a base is provided at the lower part of the outer cover 60, and an air inlet is provided on the base, and an air flow space is formed inside, and the air flow space is connected 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.

[0040] The present disclosure also provides an air conditioning cabinet, Figure 8 As shown, the base provided by any of the above embodiments is included. By providing the base, the air conditioner cabinet can take in air from the side and / or bottom of the base, and guide and distribute the airflow, so that the airflow entering the air conditioner cabinet is more uniform, thereby making the air outlet of the air conditioner cabinet closer to natural wind.

[0041] In some embodiments, in combination Figure 1As shown, the air conditioner cabinet includes a housing 1, and 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, and the air outlet 62 of the base is connected to the second air duct 20. The centrifugal fan or the axial flow fan drives the airflow to enter from the base, and the air is supplied through the second air duct 20, and the air supply effect is more natural. In addition, the base can increase the airflow in the second air duct 20. If combined with the airflow adjustment component 40, the airflow in the second air duct 20 can be diverted to the first air duct 10 to adjust the air outlet effect of the first air duct 10.

[0042] Combination Figure 1-3 As shown, the 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 connecting portion 30. 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 adjustment component 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 rotating to the first position, and conduct the connecting portion 30 to connect the first air duct 10 and the second air duct 20 when rotating to the second position.

[0043] The airflow 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 duct more compact and facilitate the appearance design of the housing 1. The connecting portion 30 is arranged 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 airflow can flow between the first air duct 10 and the second air duct 20. The airflow adjustment component 40 is arranged on the connecting portion 30 and can rotate relative to the connecting portion 30. When the airflow adjustment component 40 rotates to the first position, the connecting portion 30 is blocked to separate the first air duct 10 and the second air duct 20; when it rotates to the second position, the connecting portion 30 is opened to connect the first air duct 10 and the second air duct 20. When 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 without affecting each other. When 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. The air flows in the first air duct 10 and the second air duct 20 can be adjusted.

[0044] Through this embodiment, the air conditioner can transport airflow through the first air duct 10 and the second air duct 20 respectively, and the connection and separation states between the first air duct 10 and the second air duct 20 can be adjusted. By adjusting the state, the air supply effects of the first air duct 10 and the second air duct 20 are no longer solidified, but can change.

[0045] Optionally, the connecting portion 30 is an opening on the side wall of the second air duct 20. The side wall of the second air duct 20 is opened to achieve the connection between the first air duct 10 and the second air duct 20. Optionally, the shape of the opening is circular, elliptical, 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, elliptical, rectangular or trapezoidal. The second air duct 20 with a circular, elliptical or rectangular cross section can allow the air flow to pass smoothly. The cross-sectional shape of the second air duct 20 can be selected according to the distribution of the internal components of the shell 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, so as to facilitate the use of the heat or cold emitted by the heat exchanger 50 to adjust the air flow temperature. When the cross section is rectangular, it is also convenient for the second air duct 20 to be connected with the exhaust port of the centrifugal fan.

[0046] In some embodiments, in combination Figure 2 As shown, the airflow adjustment assembly 40 includes: a rotating shaft 41, a motor 42 and a guide plate 43. The rotating shaft 41 is rotatably disposed on the connecting portion 30; the motor 42 is connected to the rotating shaft 41 to drive the rotating shaft 41 to rotate; the guide plate 43 is fixedly connected to the rotating shaft 41 and is configured to block the connecting portion 30 when rotating to a first position, and to conduct the connecting portion 30 when rotating to a second position.

[0047] The motor 42 drives the rotating shaft 41 to rotate, thereby driving the guide plate 43 to rotate. When the guide plate 43 rotates to the first position, the connecting portion 30 is blocked to separate the first air duct 10 and the second air duct 20, and the airflow in the two air ducts flows independently. When the guide plate 43 rotates to the second position, the connecting portion 30 is opened to connect the first air duct 10 and the second air duct 20, and the airflow flows between the first air duct 10 and the second air duct 20. Through this embodiment, the airflow adjustment component 40 can adjust the action state of the first air duct 10 and the second air duct 20 by rotating, thereby changing the air supply effect of the air conditioner.

[0048] Optionally, the rotating shaft 41 extends along the edge of the guide plate 43. In this way, when the rotating shaft 41 rotates, the guide plate 43 can open or cover the connecting portion 30. By selecting the edges of the guide plate 43 at different positions to set the rotating shaft 41, different rotation effects of the guide plate 43 can be achieved. When the guide plate 43 rotates to the vertical position, it covers the connecting portion 30. When it rotates to the inclined position, it can form a drainage effect in the first air duct 10 or the second air duct 20. By adjusting the inclination direction of the guide plate 43, it is possible to choose to introduce the airflow from the first air duct 10 to the second air duct 20 or from the second air duct 20 to the first air duct 10. Optionally, the rotating shaft 41 passes through the middle of the guide plate 43 or a position close to the edge and fits the plate surface. In this way, when the guide plate 43 rotates to the second position, it can also achieve the effects of drainage and connection. Optionally, the motor 42 is arranged outside the second air duct 20. Avoid the motor 42 from affecting the airflow in the second air duct 20.

[0049] Optionally, the first position is a position covering the connecting portion 30, so that the guide plate 43 can block the connecting portion 30. Optionally, the shape of the guide plate 43 is adapted to the shape of the connecting portion 30. In this way, the connecting portion 30 will not cause spatial interference to the rotation of the guide plate 43, and when the guide plate 43 rotates to the first position, it can cover the connecting portion 30 to form a blockage.

[0050] Optionally, the second position is a position perpendicular to the side wall of the second air duct 20 or a position inclined relative to the side wall of the second air duct 20. Optionally, when the guide plate 43 is perpendicular to the side wall of the second air duct 20, the guide plate 43 blocks the second air duct 20. By designing the area of ​​the guide plate 43, the guide plate 43 blocks the second air duct 20 when it is perpendicular to the side wall of the second air duct 20, so that the airflow in the second air duct 20 can completely enter the first air duct 10, and when only the first air duct 10 is needed to transport the airflow, the airflow in the first air duct 10 can be maximized.

[0051] In some embodiments, in combination Figure 4 As shown, a first air outlet 11 and a second air outlet 21 are provided on the surface of the housing 1 . The first air outlet 11 is connected to the first air duct 10 , and the second air outlet 21 is connected to the second air duct 20 .

[0052] The airflow delivered by the first air duct 10 flows out of the housing 1 through the first air outlet 11, and the airflow delivered 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 to discharge air, so that the air conditioner can deliver air through different air outlets. By setting the position of the air outlet, 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. The first air outlet 11 and the second air outlet 21 have different shapes, and different air supply devices can be set in the first air duct 10 and the second air duct 20 respectively, for example, a cross-flow fan is set 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 the second air outlet 21. The cross-flow fan is longer in length, and the airflow generated is suitable for flowing out from the first air outlet 11. The centrifugal fan has a smaller air volume and a larger wind pressure, and is suitable for flowing out from the second air outlet 21.

[0053] 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, and the position of the air outlet can be made more compact, which is also convenient for the air conditioner to be placed indoors, so that this side discharges air toward the indoor user activity area. In some embodiments, the first air outlet 11 and the second air outlet 21 are at different heights. 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 airflow with stronger wind force can be transported 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 by the cover plate, and when the air conditioner is not running, dust and other debris are prevented from falling into the second air outlet 21 and polluting the internal environment of the air conditioner.

[0054] In some embodiments, in combination Figure 3As shown, the housing 1 also includes 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 connected to the first air duct 10; the second fan 23 is arranged in the second air duct 20, or the exhaust port is connected to the second air duct 20. The first fan 13 rotates to generate an airflow to be sent into the first air duct 10, and the second fan 23 rotates to generate an airflow to be sent into the second air duct 20. The fan is arranged in the air duct, or the exhaust port is connected to the air duct, which can realize air supply to the air duct. When in 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 at the same time to supply air. Through this embodiment, two airflows with different effects can be formed inside the air conditioner, and different air supply effects are generated from the first air outlet 11 and the second air outlet 21. In combination with the airflow regulating component 40 in the aforementioned embodiment, part or all of the airflow in the second air duct 20 can be sent into the first air duct 10, so that the air volume and air pressure of the first air outlet 11 are larger and the air supply distance is longer. Part of the airflow in the first air duct 10 can also be sent into the second air duct 20, so that the air volume of the second air outlet 21 is larger.

[0055] Optionally, combined Figure 4 As shown, the housing 1 is provided with a first air inlet 12 connected to 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 inlet grille. The first air inlet 12 is opposite to the first air outlet 11, that is, the first air outlet 11 is provided on the front side of the housing 1, and the first air inlet 12 is provided on the rear side of the housing 1. When the first fan 13 rotates, the airflow enters from the first air inlet 12 and flows through the first air duct 10 to the first air outlet 11. Optionally, the lower part of the housing 1 is provided with a second air inlet 22 connected to the second air duct 20. When the second fan 23 rotates, the airflow 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.

[0056] 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 over a long distance. Optionally, the second fan 23 is a centrifugal fan. The wind pressure of a centrifugal fan is relatively large, and a relatively strong airflow can be generated. Optionally, the second fan 23 is an axial flow fan. The flow rate of an axial flow fan is larger than that of a centrifugal fan, and the volume occupied by the axial flow fan is generally smaller than that of a centrifugal fan, and the axial flow fan can also supply air to the second air duct 20.

[0057] Optionally, combined Figure 5As shown, the second air outlet 21 is arranged on the front side of the housing 1, and the air inlet 14 is arranged on the back side of the housing 1. When the airflow of the second air duct 20 flows out from the second air outlet 21, the air inlet 14 can allow external air to enter, and form a mixed airflow with the airflow of the second air duct 20, and flow out from the second air outlet 21 together to increase the air volume. Optionally, the air inlet 14 is provided with a cover that can be opened and closed. When the cover is opened, the second air outlet 21 can deliver the mixed airflow, and when the cover is closed, the second air outlet 21 can deliver the airflow in the second air duct 20. By controlling the first fan 13 and the second fan 23 at the same time or opening them separately, multiple modes of long-distance air supply / rapid cooling / mixed air supply of the air conditioner can be realized. For example, turning on the axial flow fan alone can achieve long-distance air supply (air inlet 14 is closed) / mixed air supply (air inlet 14 is open); turning on the cross-flow fan alone can achieve rapid cooling; turning on the axial flow fan and the cross-flow fan at the same time can achieve long-distance air supply (air inlet 14 is closed) and rapid cooling; turning on the axial flow fan and the cross-flow fan at the same time can achieve mixed air supply (air inlet 14 is open) and rapid cooling.

[0058] In some embodiments, in combination Figure 3 As shown, the shell 1 also includes a heat exchanger 50. The heat exchanger 50 includes a first heat exchange part 51 and a second heat exchange part 52 connected to each other. The first heat exchange part 51 is arranged in the first air duct 10, and the second heat exchange part 52 is arranged 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 the airflow adjusts the temperature of the airflow when passing through. The second heat exchange part 52 is in the second air duct 20. Similarly, it adjusts the temperature of the airflow in the second air duct 20. Optionally, the first heat exchange part 51 and the second heat exchange part 52 are an integral structure. Optionally, the second heat exchange part 52 is bent relative to the first heat exchange part 51. The refrigerant flows in the first heat exchange part 51 and the second heat exchange part 52, and heat is exchanged with the airflow in the first air duct 10 and the second air duct 20. Optionally, the angle between the first heat exchange part 51 and the second heat exchange part 52 is α, 90°≤α<180°. In 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 perform heat exchange for the airflow inside each of them.

[0059] In some embodiments, the first air outlet 11 is arranged at the front side of the housing 1 and corresponds to the cross-flow fan, the first heat exchange portion 51 is arranged in parallel with the cross-flow fan, and the first air inlet 12 is arranged at the back side of the housing 1. In this way, the airflow enters from the first air inlet 12, flows through the first heat exchange portion 51, and has a larger interaction area with the first heat exchange portion 51, which can better exchange heat, and then flows out from the first air outlet 11 driven by 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.

[0060] Optionally, the second air duct 20 extends to the bottom of the second heat exchange part 52. After passing through the outlet of the second air duct 20, the airflow flows through the second heat exchange part 52, and after heat exchange, it can also flow toward the second air outlet 21, and then discharge from the second air outlet 21.

[0061] 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 air-conditioning cabinets. In some embodiments, the width of the second air duct 20 gradually decreases from the exhaust port 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 connected to the fan and has a small width, which can enhance the wind pressure. In addition, 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. If the width of the second air duct 20 is gradually reduced, the air flow entering the first air inlet 12 can be reduced in the narrower part of the second air duct 20.
