[0033] The present invention proposes an air guide assembly 100 for an air conditioner 200. The air conditioner 200 may be a split air conditioner 200 that is convenient for users to implement personal installation. The air conditioner 200 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 injects refrigerant 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 respectively, without assembling the refrigerant pipe and filling the refrigerant, thereby reducing the difficulty of installation and realizing personal installation by the user. However, the present design is not limited to this. In other embodiments, the air conditioner 200 of the present invention may also be an ordinary split air conditioner 200, or an integrated air conditioner 200. The air conditioner 200 includes a casing 210, and the casing 210 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.

[0034] In the embodiment of the present invention, Figures 1 to 6 As shown, 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 located inside the air outlet 212 to guide air upward, and a second air guide state 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 installed on the air guide frame 110.

[0035] In the prior art, the air conditioner 200 usually has multiple temperature control modes, such as a cooling mode and a heating mode. In the 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 will consume a lot of functions and waste electric energy. Correspondingly, in the 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 will also consume a lot of functions and waste electric energy. Therefore, in order to achieve a better temperature control effect, in the cooling mode, the air outlet 212 blows upward, and in the 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 electric energy.

[0036] In the present solution, the air conditioner 200 includes a casing 210, and a 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 make the air outlet 212 adapt to the air outlet mode under different temperature adjustment modes, an air guide assembly 100 is arranged, and the air guide plate 120 rotates to adjust the direction of the airflow 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 more vertically the air guide plate 120 is placed, the larger the upward opening of the air outlet 212 is. When the airflow is blown out from the air outlet 212, it flows upward along the extension direction of the air guide plate 120, thereby guiding the airflow of the air outlet 212 to blow upward. At this time, the air guide assembly 100 is in the first air guiding state, corresponding to the air conditioner 200 being in the cooling mode, refer to Figure 5 At this time, the air guide frame 110 is stationary and is completely located in the air outlet 212. Only the air guide plate 120 rotates upward, and the greater the rotation angle, the better the upward wind 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 only the air guide plate 120 rotates 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 on 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 adjustment effect. Therefore, in the second air guiding state, refer to Figure 6The air guide frame 110 is rotatably mounted at 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 efficiency. At this time, if the angle of the air guide plate 120 upwardly tilted relative to the horizontal direction is small, it will not It will affect the outflow efficiency of the airflow, and the air guide plate 120 opens upward at a smaller 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). It has a certain blocking effect on the airflow flowing upward from the air outlet 212, and can also play a certain role in blocking the airflow from flowing upward. When the indoor unit of the air conditioner is configured as a floor-standing unit, it has a better effect. 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 (refer 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. At this time, a better air guiding effect can be achieved, guiding the airflow of the air outlet 212 to flow downward.

[0037] Among them, a limited position guide structure 170 is arranged between the air guide plate 120 and the air guide frame 110. Since the air guide plate 120 and the air guide frame 110 are both long, they are only connected by the rotating shafts at the two opposite ends, which is unstable and difficult to ensure the movement stability of the air guide plate 120. Therefore, a limited position guide structure 170 is arranged. The limited position guide structure 170 includes a limited position guide part 171 extending along the movement path of the air guide plate 120 and a sliding part sliding along the extension direction of the limited position guide part 171. One end of the sliding part is fixed to the air guide plate 120, and the other end is slidably connected to the limited position guide part 171, so as to provide support for the air guide plate 120 and ensure the movement stability of the air guide plate 120. Preferably, the limited position guide structure 170 is arranged in the middle section of the length direction of the air guide plate 120.

[0038] Further, see 4 to Figure 6In the first wind guiding state, the wind guide plate 120 is set at a first angle with the horizontal direction, and in the second wind guiding state, the wind guide plate 120 is set at a second angle with the horizontal direction; the first angle is greater than the second angle. Specifically, in the first wind guiding state (cooling mode), the wind guide plate 120 needs to guide the airflow of the air outlet 212 upward. If the first angle is too small, it is not conducive to the airflow flowing upward. Therefore, the larger the opening of the wind guide plate 120 relative to the horizontal direction, the better the guiding effect. For example, when the wind guide plate 120 is set vertically relative to the horizontal direction, the airflow of the air outlet 212 directly flows vertically upward along the wind guide plate 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 set too large. If the air guide plate 120 is tilted upwards too much relative to the horizontal direction, it is difficult to achieve the effect of guiding the air to one side of the air conditioner 200; correspondingly, if the air guide plate 120 is tilted downwards too much relative to the horizontal direction, it may block the air outlet 212 and affect the discharge of the airflow from the air outlet 212. Therefore, the first angle is greater than the second angle. This effectively ensures the air outlet effect of the air outlet 212 of the air conditioner 200 in different temperature adjustment states.

[0039] 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 fan-shaped when it flows out from 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 directly blown on 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°, so as to achieve a better wind guiding effect. In addition, 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 adjustment effect, and affects the effect of the air guide plate 120 guiding the outflow of airflow upwards. Therefore, the angle between the air guide plate 120 and the horizontal direction is generally greater than or equal to 10°.

[0040] 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 side wall of the air guide frame 110 may affect the air guiding effect of the air guide plate 120, which is not conducive to the outflow of air flow, so 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 the horizontal direction or tilted downward. At this time, a better air guiding effect can be achieved, guiding the airflow of 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 wind 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 airflow, reduces the blowing efficiency of the airflow, 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 can ensure the outflow efficiency of the airflow.

[0041] The technical solution of the present invention is that the air guide frame 110 is rotatably installed at the air outlet 212, the air guide plate 120 is rotatably installed in the air guide frame 110, and the air outlet 212 is arranged 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 completely 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 Installed at the air outlet 212, the air guide plate 120 is rotatably installed in the air guide frame 110, and 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, thereby 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 at 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 at 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 electric energy.

[0042] In one embodiment, the air guide assembly 100 includes a first driving device 130 and a second driving device 140, wherein the first driving device 130 drives the air guide plate 120 to rotate, and the second driving device 140 drives the air guide frame 110 to rotate. Specifically, the air guide plate 120 is driven to rotate by the first driving device 130, and the air guide frame 110 is driven to rotate by the second driving device 140, so that the air guide plate 120 and the air guide frame 110 are independently rotated, and the electric driving mode is adopted, so that the user can accurately 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 turned to rotate the air guide plate 120 and the air guide frame 110, so that the user can manually turn them to a preset angle according to actual needs.

[0043] Further, the first driving device 130 is configured as a first driving motor 131, and the outer side of the air guide frame 110 has a first mounting groove 111, the first driving motor 131 is installed in the first mounting groove 111, and the driving shaft of the first driving motor 131 passes through the first mounting groove 111 and is connected to the air guide plate 120. Specifically, because the air guide frame 110 is installed to the air outlet 212, the outer periphery of the air guide frame 110 should be arranged in contact with the inner periphery of the air outlet 212, thereby reducing the possibility of accidental leakage of airflow 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 groove 111, and the first driving motor 131 is arranged in the first mounting groove 111, thereby reserving sufficient space for the installation of the first driving motor 131, and the first driving motor 131 is hidden in the air guide frame 110 to ensure the installation of the first driving 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.

[0044] 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 groove 111. The second drive motor 141 is arranged on the side of the first cover plate 142 away from the air guide frame 110. Specifically, the first cover plate 142 covers the opening of the first mounting groove 111, thereby reducing the possibility of airflow entering the first mounting groove 111. Since the gas generated by the air outlet 212 is a heat-exchanged gas, such as in the cooling mode, the airflow temperature of the air outlet 212 is relatively low, and condensation may be generated when entering the first mounting groove 111, which is difficult to discharge. Therefore, the first cover plate 142 protects the first drive motor 131, thereby improving the service life of the air guide assembly 100. Among them, the first drive motor 131 is configured as a stepping motor, so as to accurately control the rotation angle of the air guide plate 120. The first cover plate 142 is fixedly connected to the air guide frame 110, thereby facilitating the disassembly 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 .

[0045] Reference Figures 1 to 3In 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 through 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 set in the same manner, so that 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, and the transmission structure 150 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.

[0046] Further, 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 drives the first cover plate 142 to rotate through the meshing of the transmission gear 151 and the transmission tooth segment 152, thereby changing 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, and the position of the second drive motor 141 can be flexibly set, so as to facilitate the control of the space occupied by the first drive device 130 and the second drive device 140 to the air outlet 212. Among them, the first drive motor 131 is configured as a stepping motor, so as to accurately control the rotation angle of the air guide plate 120. In other embodiments, the second drive motor 141 can also drive and control the rotation angle of the air guide frame 110 through a rocker structure.

[0047] In order to further reduce the space occupied by the first drive device 130 and the second drive device 140 on the air outlet 212, in one embodiment, the first cover plate 142 forms a second mounting groove 143 on the side facing the second drive motor 141, the transmission tooth segment 152 is formed on the side wall of the second mounting groove 143, the transmission gear 151 is installed in the second mounting groove 143, the second cover plate 144 covers the second mounting groove 143, and the driving shaft of the second drive motor 141 passes through the second cover plate 144 to connect the transmission gear 151.
