If the air outlet is located at the top of the unit, during heating mode, hot air will accumulate in the upper air of the room, and the lower air will be slow to heat up, resulting in uneven indoor air temperature and difficulty in providing adequate heating effect.

[0034] The present application proposes an air guide assembly 100 for an air conditioner 200. The air conditioner 200 can be a split-type air conditioner 200 that is easy for users to install personally. It uses a flexible refrigerant pipe to connect the indoor heat exchanger of the air conditioner indoor unit and the outdoor heat exchanger of the air conditioner outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. In this way, when the user installs the equipment by himself, he only needs to fix the air conditioner indoor unit and the air conditioner outdoor unit separately, without the need to assemble the refrigerant pipe and add refrigerant, thereby reducing the difficulty of installation and enabling personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner 200 of the present application can also be an ordinary split-type air conditioner 200, or an integrated air conditioner 200. The air conditioner 200 includes a casing 210, which is provided with an air inlet and an air outlet 212, and the air outlet 212 is arranged on the top plate 211 of the casing 210.

[0035] In an embodiment of the present application, as shown in Figures 1 to 6, the air guide assembly 100 includes an air guide plate 120 and an air guide frame 110. The air guide frame 110 is rotatably arranged relative to the air outlet 212, and has a first air guide state in which it is located inside the air outlet 212 to guide air upward, and a second air guide state in which it is at least partially rotated out of the air outlet 212 to guide air toward one side of the air outlet 212; the air guide plate 120 is rotatably mounted on the air guide frame 110.

[0036] In the prior art, the air conditioner 200 usually has multiple temperature control modes, such as cooling mode and heating mode. In cooling mode, the indoor unit of the air conditioner 200 blows out cold air. Since the density of cold air is relatively high, if the air outlet 212 blows downward, it is easy to cause cold air to accumulate in the lower space, and only the lower space in the room has cold air, while the upper space is still hot air. In this way, the air conditioner 200 consumes a lot of functions and wastes electricity. Correspondingly, in heating mode, the indoor unit of the air conditioner 200 blows out hot air. Since the density of hot air is relatively high, if the air outlet 212 blows upward, it is easy to cause hot air to accumulate in the upper space, and only the upper space in the room has hot air, while the lower space is still cold air. In this way, the air conditioner 200 also consumes a lot of functions and wastes electricity. Therefore, in order to achieve a better temperature control effect, in cooling mode, the air outlet 212 blows upward, and in heating mode, the air outlet 212 blows downward, so that the cold air and hot air in the room form convection, accelerate the uniformity of indoor temperature mixing, thereby improving the temperature control effect and saving electricity.

[0037] In this solution, the air conditioner 200 includes a casing 210, and the top plate 211 of the casing 210 is provided with an air outlet 212, and the air outlet 212 is arranged horizontally. In order to adapt the air outlet 212 to the air outlet mode under different temperature adjustment modes, an air guide assembly 100 is provided, and the air guide plate 120 rotates to adjust the direction of the air flow blown out of the air outlet 212. The larger the rotation angle of the air guide plate 120 relative to the horizontal direction (assuming that the angle between the air guide plate 120 and the horizontal direction is α), that is, the air guide plate 120 rotates relative to the horizontal direction. 5 , at this time, the air guide frame 110 is stationary and entirely located in the air outlet 212, and only the air guide plate 120 rotates upward, and the greater the rotation angle, the better the upward air guiding effect. However, in the heating mode, the air flow should flow out downward, and when the air conditioner 200 is configured as a floor-standing type, the air flow can also flow out horizontally or slightly upward. Therefore, the air guide plate 120 must have a certain blocking effect on the air flow of the air outlet 212. However, if the air guide plate 120 is only rotated at a small angle relative to the horizontal direction (the angle α between the air guide plate 120 and the horizontal direction is small), on the one hand, the guiding effect of the air flow is limited, and on the other hand, the opening area of ​​the air outlet 212 is small, which is not conducive to the outflow of air flow, reduces the blowing efficiency of the air flow, and affects the temperature control effect. 6, the air guide frame 110 is rotatably mounted on the air outlet 212, and the air guide plate 120 is rotatably mounted in the air guide frame 110. The air guide frame 110 rotates at the air outlet 212 and at least partially rotates out of the air outlet 212, thereby driving one side of the air guide plate 120 to tilt out of the air outlet 212. When the corresponding air guide plate 120 is opened, the air guide plate 120 moves upward relative to the air outlet 212 by a certain distance, thereby increasing the opening area of ​​the air outlet 212 and improving the air flow outflow efficiency. At this time, if the air guide plate 120 is tilted upward relative to the horizontal direction The angle is small and will not affect the air flow outflow efficiency, and the air guide plate 120 is opened upward at a small angle relative to the air outlet 212, that is, the inclination angle of the air guide plate 120 relative to the air guide frame 110 is greater than the inclination angle of the air guide frame 110 relative to the horizontal direction (assuming that the angle between the air guide frame 110 and the horizontal direction is β, and the angle between the air guide plate 120 and the air guide frame 110 is γ), which has a certain blocking effect on the air flow flowing upward from the air outlet 212, and can also play a certain role in blocking the air flow from flowing upward, which has a better effect when the air conditioner indoor unit is configured as a floor-standing unit.When the inclination angle of the air guide plate 120 relative to the air guide frame 110 is less than or equal to the inclination angle of the air guide frame 110 relative to the horizontal direction, the air guide plate 120 is tilted downward relative to the horizontal direction (referring to Figure 6, at this time the inclination angle of the air guide plate 120 relative to the air guide frame 110 is equal to the inclination angle of the air guide frame 110 relative to the horizontal direction, corresponding to the horizontal setting of the air guide plate 120), a better air guiding effect can be achieved, guiding the airflow of the air outlet 212 to flow downward.

[0038] A limiting guide structure 170 is provided between the air deflector 120 and the air deflector frame 110. Because both the air deflector 120 and the air deflector frame 110 are relatively long, a connection solely via rotating shafts at opposite ends would be unstable and difficult to ensure the stability of the air deflector 120's movement. Therefore, the limiting guide structure 170 is provided. The limiting guide structure 170 includes a limiting guide portion 171 extending along the motion path of the air deflector 120 and a sliding portion that slides along the extension direction of the limiting guide portion 171. One end of the sliding portion is fixed to the air deflector 120, and the other end is slidably engaged with the limiting guide portion 171. This provides support for the air deflector 120 and ensures the stability of the air deflector 120. In one embodiment, the limiting guide structure 170 is provided in the middle of the lengthwise direction of the air deflector 120.

[0039] Further, referring to Figures 4 to 6 , in the first air-guiding state, the air deflector 120 is disposed at a first angle with respect to the horizontal direction, and in the second air-guiding state, the air deflector 120 is disposed at a second angle with respect to the horizontal direction; the first angle is greater than the second angle. Specifically, in the first air-guiding state (cooling mode), the air deflector 120 needs to direct the airflow from the air outlet 212 upward. If the first angle is too small, this upward airflow is not conducive. Therefore, the larger the opening of the air deflector 120 relative to the horizontal direction, the better the guiding effect. For example, when the air deflector 120 is disposed vertically relative to the horizontal direction, the airflow from the air outlet 212 flows directly vertically upward along the air deflector 120. Similarly, in the second air-guiding state (heating mode), the angle between the air guide plate 120 and the horizontal direction should not be too large. If the air guide plate 120 is tilted upward too much relative to the horizontal direction, it will be difficult to effectively guide air toward the air conditioner 200. Conversely, if the air guide plate 120 is tilted downward too much relative to the horizontal direction, it may block the air outlet 212, affecting the discharge of air from the air outlet 212. Therefore, the first angle is greater than the second angle. This effectively ensures the air outlet 212 of the air conditioner 200 is effective in different temperature adjustment states.

[0040] Furthermore, the angle between the air guide plate 120 and the horizontal direction is less than or equal to 55°. Specifically, because the airflow is arranged in a fan shape when flowing out of the air outlet 212, when the angle between the air guide plate 120 and the horizontal direction is greater than 55°, the inclination of the air guide plate 120 relative to the horizontal direction is too large. At this time, if the air conditioner 200 is set close to the wall, part of the airflow flowing out of the air outlet 212 may be blown directly onto the wall, causing unnecessary heat loss. Therefore, the angle between the air guide plate 120 and the horizontal direction is less than or equal to 55°, thereby achieving a better air guiding effect. Moreover, the angle between the air guide plate 120 and the horizontal direction should not be too small, which is not conducive to the outflow of airflow, affects the blowing efficiency of the airflow, affects the temperature control effect, and affects the effect of the air guide plate 120 in guiding the outflow of air upward. Therefore, the angle between the air guide plate 120 and the horizontal direction is generally greater than or equal to 10°.

[0041] In another embodiment, the angle between the air guide frame 110 and the horizontal direction is less than or equal to 35°, and the angle between the air guide plate 120 and the air guide frame 110 is greater than or equal to 25° and less than or equal to 45°. Specifically, if the angle between the air guide frame 110 and the horizontal direction is greater than 35°, the sidewalls of the air guide frame 110 may affect the air guiding effect of the air guide plate 120, hindering the outflow of air. Therefore, the angle between the air guide frame 110 and the air outlet 212 is less than or equal to 35°. When the angle between the air guide plate 120 and the air guide frame 110 is greater than 35°, the air guide plate 120 opens upward at a smaller angle relative to the air outlet 212, which has a certain blocking effect on the airflow flowing upward from the air outlet 212, and can also play a certain role in guiding the airflow to flow out to one side of the air conditioner 200. When the angle between the air guide plate 120 and the air guide frame 110 is less than or equal to 35°, the air guide plate 120 is set parallel to or tilted downward relative to the horizontal direction, and a better air guiding effect can be achieved at this time, guiding the airflow from the air outlet 212 to flow obliquely downward to the air conditioner 200. However, the angle between the air guide plate 120 and the air guide frame 110 should not be too large. If it is greater than 45°, the air guiding effect of the air guide plate 120 will be reduced, and it will be difficult to guide the airflow downward. If the angle between the air guide plate 120 and the air guide frame 110 is less than 25°, the opening area of ​​the air guide plate 120 relative to the air outlet frame 160 is small, which is not conducive to the outflow of air, reduces the blowing efficiency of the air flow, and affects the temperature control effect. Therefore, the angle between the air guide plate 120 and the air guide frame 110 is greater than or equal to 25° and less than or equal to 45°, which has a better effect of guiding the airflow downward and ensures the outflow efficiency of the airflow.

[0042] The technical solution of the present application is to rotate and install the air guide frame 110 at the air outlet 212, and the air guide plate 120 is rotated and installed in the air guide frame 110, and the air outlet 212 is provided on the top plate 211 of the casing 210 of the air conditioner 200. In the first air guide state, the air guide frame 110 is stationary and is entirely located in the air outlet 212. Only the air guide plate 120 rotates upward to guide the air upward and guide the airflow of the air outlet 212 to flow out upward. In the second air guide state, the air guide frame 110 rotates and the air guide plate 120 rotates and ... The air guide plate 120 is installed at the air outlet 212 and is rotatably installed in the air guide frame 110. The air guide frame 110 rotates at the air outlet 212 and at least partially rotates out of the air outlet 212, thereby driving one side of the air guide plate 120 to tilt out of the air outlet 212. When the corresponding air guide plate 120 is opened, the air guide plate 120 moves upward a certain distance relative to the air outlet 212, thereby guiding the airflow to blow toward one side of the air conditioner 200 and reducing the air outlet height of the air outlet 212. The air conditioner 200 has a cooling mode and a heating mode. In the cooling mode, the air guide frame 110 is in a first air guiding state, so that the airflow from the air outlet 212 in the cooling mode is blown upward; in the heating mode, the air guide frame 110 is in a second air guiding state, so that the airflow from the air outlet 212 in the heating mode flows out to one side of the air conditioner 200; thereby adapting to different temperature control modes of the air conditioner 200, improving the temperature control effect of the air conditioner 200, accelerating the rapid mixing of indoor temperature, and saving electricity.

[0043] In one embodiment, the air guide assembly 100 includes a first drive device 130 and a second drive device 140. The first drive device 130 drives the air guide plate 120 to rotate, and the second drive device 140 drives the air guide frame 110 to rotate. Specifically, the first drive device 130 drives the air guide plate 120 to rotate, and the second drive device 140 drives the air guide frame 110 to rotate, so that the air guide plate 120 and the air guide frame 110 rotate independently. The use of an electric drive mode facilitates the user to precisely control the rotation angle of the air guide plate 120 and the air guide frame 110. In other embodiments, the air guide plate 120 and the air guide frame 110 can also be manually adjusted to a preset angle according to actual needs.

[0044] Furthermore, the first drive device 130 is configured as a first drive motor 131. The outer side of the air guide frame 110 has a first mounting slot 111. The first drive motor 131 is mounted in the first mounting slot 111, and the drive shaft of the first drive motor 131 passes through the first mounting slot 111 and is connected to the air guide plate 120. Specifically, because the air guide frame 110 is mounted to the air outlet 212, the outer periphery of the air guide frame 110 should be arranged to fit the inner periphery of the air outlet 212, thereby reducing the possibility of accidental leakage of air from between the air guide frame 110 and the air outlet 212 and ensuring sufficient air outlet area. Therefore, the outer side of the air guide frame 110 is partially recessed inward to form the first mounting slot 111. The first drive motor 131 is arranged in the first mounting slot 111, thereby reserving sufficient space for the installation of the first drive motor 131 and concealing the first drive motor 131 in the air guide frame 110 to ensure the installation of the first drive motor 131. The driving shaft of the first driving motor 131 passes through the first mounting slot 111 and is connected to the air guide plate 120 , thereby driving the air guide plate 120 to rotate.

[0045] Furthermore, the second drive device 140 includes a second drive motor 141 and a first cover plate 142. The first cover plate 142 covers the opening of the first mounting slot 111. The second drive motor 141 is located on the side of the first cover plate 142 facing away from the air guide frame 110. Specifically, the first cover plate 142 covers the opening of the first mounting slot 111, thereby reducing the possibility of airflow entering the first mounting slot 111. Because the gas generated by the air outlet 212 is heat-exchanged gas, for example, in cooling mode, the airflow temperature of the air outlet 212 is relatively low. When entering the first mounting slot 111, condensation may be generated, which is difficult to discharge. Therefore, the first cover plate 142 protects the first drive motor 131, thereby increasing the service life of the air guide assembly 100. The first drive motor 131 is configured as a stepper motor, thereby precisely controlling the rotation angle of the air guide plate 120. The first cover plate 142 is fixedly engaged with the air guide frame 110, thereby facilitating the removal and assembly of the first drive motor 131. Of course, in other implementations, the first cover plate 142 may also be bonded to the air guide frame 110 .

[0046] 1 to 3 , in one embodiment, a transmission structure 150 is provided between the second drive motor 141 and the first cover plate 142 , and the second drive motor 141 drives the air guide frame 110 to rotate via the transmission structure 150. Specifically, the second drive motor 141 drives the first cover plate 142 to rotate, thereby driving the air guide frame 110 to rotate. However, if the second drive motor 141 directly drives the first cover plate 142 to rotate, the rotation axes of the second drive motor 141, the first cover plate 142, and the air guide frame 110 must be arranged at the same position. In this case, the rotation angle of the air guide frame 110 is difficult to control, the rotation process is unstable, and the installation position of the second drive motor 141 is limited. Therefore, a transmission structure 150 is provided, which can change the rotation axis of the first cover plate 142 and the air guide frame 110, thereby improving the stability and accuracy of the second drive motor 141 driving the air guide frame 110 to rotate.

[0047] Furthermore, the transmission structure 150 includes a transmission gear 151 and a transmission tooth segment 152 provided on the first cover plate 142. The transmission gear 151 meshes with the transmission tooth segment 152, and the second drive motor 141 drives the transmission gear 151 to rotate. Specifically, the second drive motor 141 drives the transmission gear 151 to rotate, and through the meshing of the transmission gear 151 and the transmission tooth segment 152, it drives the first cover plate 142 to rotate, thereby changing the rotation axis of the first cover plate 142 and the air guide frame 110. This improves the stability and accuracy of the second drive motor 141-driven rotation of the air guide frame 110, and allows for flexible setting of the position of the second drive motor 141, thereby facilitating control of the space occupied by the first drive device 130 and the second drive device 140 relative to the air outlet 212. The first drive motor 131 is configured as a stepping motor, thereby precisely controlling the rotation angle of the air guide plate 120. In other embodiments, the second drive motor 141 can also be driven and controlled by a rocker structure to rotate the air guide frame 110.

[0048] To further reduce the space occupied by the first drive device 130 and the second drive device 140 relative to the air outlet 212, in one embodiment, a second mounting slot 143 is formed on the side of the first cover plate 142 facing the second drive motor 141. A transmission tooth segment 152 is formed on the sidewall of the second mounting slot 143. A transmission gear 151 is mounted in the second mounting slot 143. The second cover plate 144 covers the second mounting slot 143. The drive shaft of the second drive motor 141 passes through the second cover plate 144 and connects to the transmission gear 151. Specifically, the outer side of the first cover plate 142 is partially recessed inward to form the second mounting slot 143. The transmission tooth segment 152 is formed on the sidewall of the second mounting slot 143. The transmission gear 151 is disposed within the second mounting slot 143. This leaves sufficient space for the transmission gear 151 and the transmission tooth segment 152 to engage and transmit power, thereby reducing the axial space occupied by the transmission gear 151 and the transmission tooth segment 152, thereby ensuring a sufficient air outlet area. The second cover plate 144 covers at least a portion of the opening of the second installation slot 143 , thereby protecting the driving structure, thereby increasing the service life of the air guide assembly 100 and facilitating the installation of the second drive motor 141 .

[0049] Referring again to Figures 1 to 4, to reduce the possibility of accidental leakage of airflow between the air outlet 212 and the air guide frame 110, in one embodiment, the air guide assembly 100 further includes an air outlet frame 160. The air outlet frame 160 is disposed inside the air outlet 212 and is provided with an air outlet channel 161 communicating with the air outlet 212. The air guide frame 110 is rotatably mounted on the air outlet frame 160, and the second driving device 140 is disposed outside the air outlet frame 160. The inner wall of the air outlet channel 161 partially overlaps with the side wall of the air guide frame 110. By extending the overlapping area between the two, the resistance to airflow outflow is further increased, the possibility of accidental leakage of airflow between the air outlet 212 and the air guide frame 110 is reduced, and the rotation of the air guide frame 110 is further guided, thereby improving the rotational stability of the air guide frame 110. The second drive motor 141 is at least partially arranged on the outside of the air outlet frame 160. In this embodiment, the second drive motor 141 is arranged on the outside of the air outlet frame 160, that is, outside the second air outlet 212, thereby further reducing the space occupied by the second drive device 140 and ensuring sufficient air outlet area.

[0050] In one embodiment, the air guide frame 110 has an air guide sidewall 112 disposed away from its rotational connection side, and the cross-section of the air guide sidewall 112 is arc-shaped. Specifically, along the width direction of the air guide frame 110, that is, the width direction of the air conditioner 200 in which the air guide frame 110 is located, one side of the air guide frame 110 is connected to the air outlet 212, and the other side is the air guide sidewall 112. The cross-section of the air guide sidewall 112 is arc-shaped, thereby reducing the possibility of interference between the air guide frame 110 and the air outlet frame 160 or the air outlet channel 161 during rotation, and further guiding the rotation of the air guide frame 110, thereby improving the smoothness of the rotation of the air guide frame 110.

[0051] This application also provides an air conditioner 200, which includes a housing 210 and an air guide assembly 100. The specific structure of the air guide assembly 100 is similar to the above-mentioned embodiments. Since this air conditioner 200 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here. Among them, the top plate 211 of the housing 210 is provided with an air outlet 212, and the air guide assembly 100 is located at the air outlet 212.
