Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioner. Background Art

[0002] Air conditioners are widely used in the market and are essential electrical appliances for people's daily life and work. In the related technology, air conditioners suck indoor air into the air conditioner, exchange heat with the air through heat exchange devices, cool or heat the air, and then blow the heat-exchanged air out from the air outlet. Air conditioners are usually equipped with an air outlet structure to guide the air flow, which can guide the heat-exchanged air to be blown out according to the air supply angle required by the user.

[0003] However, traditional air conditioners have poor air flow guidance effects, especially when emitting hot air. Since hot air tends to float upward, traditional air conditioners cannot effectively guide the hot air to flow to the lower spaces in the room, resulting in heating stratification between the upper and lower spaces in the room and a large temperature difference, which affects the user experience. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides an air conditioner with better wind guiding effect, which can well guide the airflow to flow to the lower space in the room, reduce the indoor temperature difference, and improve the user experience.

[0005] The air conditioner according to the embodiment of the utility model comprises:

[0006] A housing, comprising a top wall, wherein the housing is provided with a first opening adjacent to the top wall;

[0007] An air guide assembly is rotatably disposed at the first opening and can be rotatably switched between a first position and a second position, wherein the air guide assembly comprises an air guide portion, and an air outlet is disposed on one side of the air guide portion;

[0008] When the air guide assembly is in the first position, the air guide portion is located inside the casing, and the air outlet is connected to the first opening; when the air guide assembly rotates from the first position to the second position, at least a portion of the air guide portion rotates out of the casing through the first opening, so that the air outlet is located outside the casing and faces away from the top wall.

[0009] The air conditioner according to the embodiment of the utility model has at least the following beneficial effects: the air guide assembly is configured to be rotatable, and when the air guide assembly rotates, the air guide portion is driven to rotate, so that the airflow can be guided to flow in different directions, and the airflow can be made to flow out according to the air supply angle required by the user, and the air guide assembly can realize the wind sweeping function when it continuously rotates between the first position and the second position. When the air guide assembly is in the first position, the air guide portion guides the airflow to flow directly out of the first opening of the casing. When the air guide assembly is in the second position, at least part of the structure of the air guide portion rotates out of the casing through the first opening, and the part of the air guide portion located outside the casing can continue to guide the airflow, which can significantly improve the air guiding effect. Moreover, when the air guide assembly rotates out of the casing, the air outlet also rotates out of the casing and faces away from the top wall of the casing, that is, the air outlet faces the lower space in the room, so that the air guide part cooperates with the air outlet to guide the airflow to flow to the lower space in the room, improving the defect of poor downward air guiding effect of traditional air conditioners. Especially when the air conditioner emits hot air, the air guide part can better guide the hot air flow downward, avoiding the hot air floating up and unable to flow to the lower space in the room, which greatly improves the heating stratification problem, can reduce the indoor temperature difference, and improve the user experience.

[0055] The present application provides an air conditioner.

[0056] Specifically, the air conditioner provided by the present application aims to solve the problem that the air flow of the traditional air conditioner is poor, the air flow cannot be directed to the lower space in the room, and the upper and lower spaces in the room have a large temperature difference. The air conditioner is particularly suitable for floor-standing air conditioners. Of course, the air conditioner provided by the present application can also be applied to vertical wall-mounted air conditioners, mobile air conditioners, etc. The following will mainly take floor-standing air conditioners as an example to explain the present application in detail.

[0057] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an air conditioner according to an embodiment of the utility model. Figure 2 The first cross-sectional view of the air conditioner of the embodiment of the utility model. In the embodiment of the present application, the air conditioner 10 includes a housing 100, a heat exchange assembly 200, a fan assembly 300 and an air guide assembly 400.

[0058] The housing 100 is used to form the overall outer contour of the air conditioner 10, and at the same time positions, supports and protects the electronic control components, functional components and mechanical components inside the air conditioner 10. For example, a storage space is formed inside the housing 100, and the heat exchange component 200, the fan component 300 and the air guide component 400 can be positioned and installed in the storage space. It can be understood that the housing 100 can be provided with a first opening 130a and a second opening (not marked) for air to pass through, wherein the first opening 130a is an air outlet opening, and the second opening is an air inlet opening.

[0059] like Figure 1 As shown, the housing 100 includes a top wall 110, a bottom wall 120, and a first wall body 130 connected between the top wall 110 and the bottom wall 120. The top wall 110 is the upper wall surface of the housing 100, the bottom wall 120 is the lower wall surface of the housing 100, and the first opening 130a is provided on the first wall body 130 and is adjacent to the top wall 110. The first wall body 130 is the front wall body of the housing 100, that is, the front wall body of the air conditioner 10. That is to say, the first opening 130a is provided at a higher position on the front of the housing 100, so that air can be sent to a farther position in the room.

[0060] It can be understood that the heat exchange assembly 200 is a core component of the air conditioner 10, and the heat exchange assembly 200 is used to perform heat exchange on the air entering the housing 100 to change the air temperature. For example, the heat exchange assembly 200 may include a refrigeration device such as an evaporator, and the refrigeration device can cool the air entering the housing 100 to reduce the air temperature and realize the refrigeration function of the air conditioner 10. The heat exchange assembly 200 may also include a heating device such as an electric heater, and the heating device can heat the air entering the housing 100 to increase the air temperature and realize the heating function of the air conditioner 10.

[0061] The fan assembly 300 is used to provide power to promote air flow. When the fan assembly 300 is working, it rotates at a high speed, which can form a negative pressure in the housing 100, and can draw the air outside the housing 100 into the housing 100 through the second opening, and at the same time, the air in the housing 100 that has been heat exchanged by the heat exchange assembly 200 is blown out of the housing 100 through the first opening 130a.

[0062] The wind guide component 400 is used to guide the airflow. The wind guide component 400 can change the direction of the airflow and can make the airflow blow out according to the outlet angle required by the user.

[0063] In the related technology, traditional air conditioners have poor air guiding effect, especially when emitting hot air. Since hot air tends to float up, traditional air conditioners cannot effectively guide the hot air to flow to the lower spaces in the room, resulting in heating stratification between the upper and lower spaces in the room, with a large temperature difference, which affects the user experience.

[0064] The wind guide assembly 400 provided in the embodiment of the present application can solve the above-mentioned problem. In the embodiment of the present application, the wind guide assembly 400 is rotatably disposed at the first opening 130a. The wind guide assembly 400 includes an wind guide portion 410, and an air outlet 410b is disposed on one side of the wind guide portion 410.

[0065] It is understandable that the wind guide assembly 400 is configured to rotate as a whole, so that the wind guide portion 410 can rotate, and the guide angle of the airflow can be changed to guide the air to flow in different directions. When in use, the guide angle of the wind guide portion 410 can be adjusted by controlling the rotation of the wind guide portion 410, and the airflow can be guided to blow out according to the air supply angle required by the user.

[0066] Please refer to Figure 3 and Figure 4 , Figure 3 This is a cross-sectional view of the air conditioner according to the embodiment of the utility model when the air guide assembly is in the first position. Figure 4 1 is a cross-sectional view of the air conditioner of the embodiment of the utility model when the air guide assembly is in the second position. In the embodiment of the present application, the air guide assembly 400 can be rotated and switched between the first position and the second position. When the air guide assembly 400 is in the first position, the air guide portion 410 is located in the housing 100, and the air outlet 410b is connected to the first opening 130a; when the air guide assembly 400 rotates from the first position to the second position, at least part of the air guide portion 410 rotates out of the housing 100 through the first opening 130a, so that the air outlet 410b is located outside the housing 100 and faces away from the top wall 110.

[0067] Then, the air guide assembly 400 of the embodiment of the present application can rotate between the inside of the casing 100 and the outside of the casing 100. When the air guide assembly 400 is located inside the casing 100, the air outlet 410b of the air guide assembly 400 is connected to the first opening 130a, and the air guide portion 410 can guide the air flow in the casing 100 and flow out directly from the first opening 130a. When the air guide assembly 400 rotates out of the casing 100, at least part of the structure of the air guide portion 410 rotates out of the casing 100, and at the same time, the air outlet 410b also rotates out of the casing 100. At this time, the part of the air guide portion 410 located inside the casing 100 can guide the air inside the casing 100 to flow out from the first opening 130a, and the part of the air guide portion 410 located outside the casing 100 can guide the airflow flowing out of the first opening 130a to continue to flow along the air guide portion 410 until it is blown out from the air outlet 410b. In other words, the air guide portion 410 of the embodiment of the present application can continue to guide the airflow flowing out of the casing 100, and has a better air guiding effect compared to traditional air conditioners that can only guide the airflow inside the air conditioner.

[0068] Moreover, when the air guide portion 410 rotates out of the casing 100, the air outlet 410b of the air guide portion 410 faces away from the top wall 110. In other words, the air outlet 410b of the air guide portion 410 faces the bottom wall 120 of the casing 100, that is, the air outlet 410b faces the indoor floor (it should be understood that the direction here can be a straight direction or an inclined direction), so that the air guide portion 410 can guide the air to flow downward toward the lower space in the room. Then, the present application sets an air guide part 410 that can be rotated out of the casing 100, and the air outlet 410b is facing away from the top wall 110 when rotating out of the casing 100, so that the air guide component 400 can well guide the airflow to flow downward, which can improve the defect that the air outlet 410b of the traditional vertical air conditioner is relatively high and it is not easy to blow the air to a low place. Especially when the air conditioner is in heating mode, the air guide part 410 can better guide the hot air flow downward, and avoid the situation where the hot air cannot flow to the low space in the room due to its floating characteristics, which greatly reduces the problem of heating stratification, can reduce the indoor temperature difference, and improve the heating effect.

[0069] In the air conditioner 10 provided in the embodiment of the present application, the air guide assembly 400 is configured to be rotatable between a first position and a second position, and the air guide assembly 400 includes an air guide portion 410 and an air outlet 410b formed on one side of the air guide portion 410. When the air guide assembly 400 rotates, the air guide portion 410 is driven to rotate, so that the airflow can be guided to flow in different directions, and the airflow can be made to flow out according to the air supply angle required by the user, and the air guide assembly 400 can realize the wind sweeping function when it continuously rotates between the first position and the second position. When the air guide assembly 400 is in the first position, the air guide portion 410 guides the airflow to flow directly out of the first opening 130a of the housing 100. When the air guide assembly 400 is in the second position, at least part of the structure of the air guide portion 410 is rotated out of the casing 100 through the first opening 130a, and the part of the air guide portion 410 located outside the casing 100 can continue to guide the airflow. Compared with the traditional air conditioner that can only guide the air inside the air conditioner, the air guiding effect can be significantly improved; moreover, when the air guide assembly 400 is rotated out of the casing 100, the air outlet 410b is also rotated out of the casing 100 and faces away from the top wall 110 of the casing 100, that is, the air outlet 410b faces the lower space in the room, so that the air guide portion 410 cooperates with the air outlet 410b to guide the airflow to flow to the lower space in the room well, improving the defect of the poor downward air guiding effect of the traditional air conditioner, especially when the air conditioner 10 emits hot air, the air guide portion 410 can better guide the hot air flow downward to avoid the hot air floating up and unable to flow to the lower space in the room, which well improves the heating stratification problem, can reduce the indoor temperature difference, and improve the user experience.

[0070] It should also be pointed out that the embodiment of the present application sets the first opening 130a on the first wall 130, that is, the front of the housing 100, rather than on the top wall 110, so that the air guide assembly 400 can be rotated out from the front of the housing 100. For a floor-standing air conditioner, the air guide assembly 400 rotates out of the housing 100 to utilize the space on the front side of the housing 100, and will not increase the height of the air conditioner 10 and limit the placement of the air conditioner 10. Moreover, the front side of the housing 100 can provide a wider open space, which is conducive to the air outlet of the air guide assembly 400 and will not affect the rotation of the air guide assembly 400. More importantly, the air guide assembly 400 can generate better downward pressure on the airflow by guiding the airflow out of the front of the housing 100, thereby achieving a better downward wind guiding effect.

[0071] Please refer to Figure 5 , Figure 5 The structure diagram of the air guide assembly in the air conditioner room of the embodiment of the utility model is shown in FIG. The air guide assembly 400 includes a first rotating shaft 414, and the air guide assembly 400 is rotatably mounted on the housing 100 via the first rotating shaft 414. The air guide assembly 400 can pitch and rotate relative to the first wall 130 around the axis of the first rotating shaft 414 to achieve the function of sweeping air up and down.

[0072] The first opening 130a is rectangular or rounded, and includes a first side (not shown) away from the top wall 110. The first rotating shaft 414 is rotatably mounted on the housing 100 and disposed close to the first side, so that the air guide portion 410 can rotate out of the housing 100 through the first opening 130a, and when the air guide portion 410 rotates out of the housing 100, the air outlet 410b can face away from the top wall 110.

[0073] like Figure 5 As shown, the air guide portion 410 includes an air outlet end wall 410a disposed on one side of the air outlet 410b. It can be understood that the air outlet end wall 410a is located on the air outlet side of the air guide portion 410. Figure 3 When the air guide assembly 400 is in the first position, the air outlet end wall 410a is disposed close to the first wall 130 .

[0074] That is to say, when the air guide assembly 400 is located in the casing 100, the air outlet end wall 410a of the air guide portion 410 is close to the first wall body 130, so that the end of the air guide portion 410 is close to the first opening 130a, so that the airflow is still guided by the air guide portion 410 when flowing out from the first opening 130a, thereby improving the air guiding effect.

[0075] Please combine Figure 4 And refer to Figure 6 , Figure 6 The air conditioner of the present utility model is a schematic diagram of a state when the air guide assembly is in the second position. When the air guide assembly 400 is in the second position, the air outlet end wall 410a is inclined relative to the first wall 130 to form a first angle θ, and the angle of the first angle θ is greater than 0° and less than or equal to 60°.

[0076] Among them, the angle range of the first angle θ is obtained by the applicant of this application after multiple wind outlet tests. When the angle of the first angle θ is within the above-mentioned angle range, the air guide component 400 has a good wind guiding effect, and can well guide the airflow to flow to the lower space of the room, especially to meet the demand of blowing hot air downward. At the same time, within this angle range, the structure of the air guide component 400 itself has little obstruction to the airflow, and can ensure a larger wind speed and air volume.

[0077] In one embodiment, when the air guide assembly 400 is configured to be in the second position, the angle between the air outlet end wall 410a and the first wall body 130 is 60°.

[0078] Please combine Figure 5 And refer to Figure 7 , Figure 7 for Figure 5A cross-sectional view of the middle air guide assembly along section AA. The air guide portion 410 includes a top plate 411 and a first side plate 412 and a second side plate 413 connected to opposite ends of the top plate 411. The top plate 411, the first side plate 412 and the second side plate 413 enclose an air guide channel 410c. A first air guide surface 4111 is formed on one side of the top plate 411 facing the air guide channel 410c. The first air guide surface 4111 is used to guide the air entering the air guide channel 410c to flow along the first air guide surface 4111 to the air outlet 410b.

[0079] like Figure 5 and Figure 7 As shown, the air guide portion 410 is in a frame shape (or shell shape) as a whole, and the air outlet end wall 410a is an end surface formed by connecting the same end of the top plate 411, the first side plate 412 and the second side plate 413.

[0080] It can be understood that the air guide 410 mainly guides the airflow through the first air guide surface 4111 of the top plate 411, and the direction of the airflow can be changed by driving the first air guide surface 4111 to rotate when the air guide 410 rotates. Since the air sweeping is achieved by driving the first air guide surface 4111 to rotate through the overall rotation of the air guide 410, there is no rotation space limitation in the structure of the first air guide surface 4111. Compared with the air guide plate of the traditional air conditioner, the size of the first air guide surface 4111 can be designed to be larger, so that the airflow entering the air guide 410 has a larger contact area with the first air guide surface 4111, so that the airflow can be fully guided; at the same time, the size of the first air guide surface 4111 can be designed to be longer, which can increase the air guide path of the airflow, so that the airflow flows to a farther position in the indoor space according to the direction guided by the first air guide surface 4111, greatly improving the wind sweeping effect.

[0081] The first side plate 412 and the second side plate 413 play an auxiliary guiding role in the airflow. The friction between the airflow blown out from the fan assembly 300 and the inner wall of the casing 100 can easily cause airflow turbulence, and the first side plate 412 and the second side plate 413 can limit the air blown out by the fan assembly 300 to flow in the air guide channel 410c, avoiding the airflow from rubbing against the inner wall of the casing 100 and making the airflow blown out from the air outlet 410b more stable and orderly.

[0082] Moreover, the first side panel 412 and the second side panel 413 are used as a supporting structure for connecting the top panel 411. On the one hand, the overall strength of the wind guide portion 410 can be enhanced to prevent the wind guide portion 410 from being deformed by a large wind force, especially preventing the top panel 411 from being deformed. On the other hand, there is enough area on the first side panel 412 and the second side panel 413 to set a rotating structure to better realize the overall rotation of the wind guide portion 410.

[0083] In one embodiment, if Figure 5As shown, the first rotating shaft 414 includes a first shaft (not marked) and a second shaft (not marked), the first shaft is connected to the outer wall of the first side plate 412, the second shaft is connected to the outer wall of the second side plate 413, and the axis of the first shaft coincides with the axis of the second shaft, and the air guide portion 410 is rotatably installed on the casing 100 through the first shaft and the second shaft.

[0084] The air guide 410 further includes a support rod 415, which is connected between the first side plate 412 and the second side plate 413 and is located on a side of the air outlet 410b away from the top plate 411. It can be understood that the support rod 415 is used to play a supporting role to further enhance the overall strength of the air guide 410 and prevent the air guide 410 from being deformed.

[0085] In order to better guide the air flow, in one embodiment, the first air guiding surface 4111 extends from an end of the top plate 411 close to the air outlet 410b to an end away from the air outlet 410b.

[0086] In this way, the first wind guide surface 4111 is designed to be long enough to allow the airflow to flow along the first wind guide surface 4111 for a longer distance, so that the airflow can maintain a longer distance in the outlet direction after being blown out from the air outlet 410b, thereby achieving a better wind guiding effect.

[0087] The first air guiding surface 4111 may be an inclined surface, an arc surface, or a stepped surface composed of multiple surfaces.

[0088] In order to better guide the air to blow to the indoor space at a suitable air supply angle, in one embodiment, the first air guide surface 4111 is designed as a curved surface. It can be understood that the curved surface can more easily guide the airflow to achieve a larger angle of flow direction change, and the curved surface can more smoothly guide the airflow to change the flow direction and reduce noise.

[0089] For example, when the airflow direction blown out by the fan assembly 300 in the housing 100 is in the vertical direction (the vertical direction here is the direction of gravity, that is, the height direction of the housing 100), and the user needs the airflow direction to be in the horizontal direction, the air guide portion 410 should guide the airflow direction to achieve a 90° change. By designing the first air guide surface 4111 as a curved surface, when the airflow blown out by the fan assembly 300 moves to the first air guide surface 4111, it flows along the curved surface of the first air guide surface 4111 and gradually changes the flow angle. The airflow gradually changes from flowing in the vertical direction to flowing in the horizontal direction. This process is gradual and progressive, and the airflow guidance is smoother. Moreover, the resistance to the airflow blowing to the curved surface is relatively small, and it will not form a return air obstruction, nor will it disturb the airflow blown in from behind, which can reduce the air outlet noise.

[0090] In one embodiment, the first air guide surface 4111 is designed to be approximately an arc surface, and the central angle of the arc surface where the first air guide surface 4111 is located is approximately 90°, so that after the air flows out of the air outlet 410b along the first air guide surface 4111 from the air inlet end of the air guide part 410, the airflow can be rotated at an angle of nearly 90° and blown into the indoor space.

[0091] In one embodiment, please refer to Figure 2 and Figure 3 The fan assembly 300 includes an axial flow fan 300 a , and the rotation axis direction of the axial flow fan 300 a is parallel to the height direction of the housing 100 .

[0092] like Figure 2 As shown, the axial flow fan 300a is arranged between the air guide component 400 and the heat exchange component 200. The axial flow fan 300a is used to provide power to draw air outside the casing 100 into the casing 100 to exchange heat with the heat exchange component 200, and blow the heat-exchanged air to the air guide component 400.

[0093] It can be understood that the axial flow fan 300a refers to a type of fan in which the airflow direction is in the same direction as the axis of the fan blade. In this embodiment, the rotation axis direction of the axial flow fan 300a is set parallel to the height direction of the housing 100, that is, the rotation axis of the axial flow fan 300a is set in the vertical direction, so that the axial flow fan 300a can drive the air after heat exchange to flow directly upward in the vertical direction.

[0094] Then, this embodiment adopts the axial flow fan 300a as the power component to drive the air flow, and the axial direction of the axial flow fan 300a is set in the vertical direction, so that the air entering the casing 100 can be blown directly to the air guide component 400 from bottom to top. There is no need to set up other air duct structures between the axial flow fan 300a and the air guide component 400, the wind resistance is small, and the wind speed and air volume loss can be reduced. Such a fan layout can better cooperate with the air guide component 400 to guide the air, thereby improving the wind guiding effect and air outlet efficiency.

[0095] Moreover, by adopting the axial flow fan 300a, compared with adopting other fans such as centrifugal fans or cross-flow fans, the axial flow fan 300a has a higher fan efficiency under the same working conditions, and can generate a larger wind speed and air volume at low power, so that the air conditioner 10 can adopt a low-power axial flow fan 300a, on the one hand, not only can the fan cost be reduced to reduce the production cost, but also on the other hand, the fan operation power consumption can be reduced, thereby reducing the user's use cost. In addition, the axial flow fan 300a has a relatively simple structure, does not have a large air duct structure or wind wheel structure, and has a small overall volume, which can reduce the space occupied in the housing 100 and reduce the overall volume of the air conditioner 10.

[0096] To further improve fan performance, please continue to refer to Figure 3 The axial flow fan 300a includes a driving motor 310, a first impeller 320, and a second impeller 330. The first impeller 320 is connected to the output shaft of the driving motor 310, and the first impeller 320 can rotate under the drive of the driving motor 310. The second impeller 330 is fixed to the air outlet side of the first impeller 320, and the axis of the second impeller 330 coincides with the axis of the first impeller 320.

[0097] The second impeller 330 is fixed to the air outlet side of the first impeller, which means that the second impeller 330 is located on the air outlet side of the first impeller 320, and the second impeller 330 is always fixed. The second impeller 330 can be fixedly connected to the drive motor 310, for example, the second impeller 330 can be connected to the housing of the drive motor 310. Of course, in other optional embodiments, the second impeller 330 can also be fixed to a portion of the housing 100 close to the air outlet side of the first impeller 320.

[0098] Specifically, during the operation of the axial flow fan 300a, the first impeller 320 rotates at a high speed driven by the driving motor 310, generating negative pressure in the casing 100, and can draw external air into the casing 100 and flow toward the axial flow fan 300a. When the air flows through the first impeller 320, it is accelerated and pressurized by the first impeller 320 and flows to the second impeller 330. Since the second impeller 330 is in a stationary state, the airflow and wind pressure are further enhanced when the airflow flows through the second impeller 330, so that the outlet airflow has a higher wind speed and wind pressure, thereby enhancing the fan performance.

[0099] Since the air guide assembly 400 needs to rotate in the housing 100 , the housing 100 needs to be designed to avoid the air guide assembly 400 according to the movement trajectory of the air guide assembly 400 to prevent the air guide assembly 400 from interfering with the wall of the housing 100 .

[0100] In order to simplify the avoidance design of the housing 100, the top plate 411 can be configured as an arc-shaped plate. In one embodiment, the top plate 411 is configured as an arc-shaped plate.

[0101] It can be understood that by setting the top plate 411 as an arc plate, the distance from each part of the top plate 411 to the axis of the first rotating shaft 414 is the same. Then, when the air guide part 410 rotates, the movement trajectory of each part of the air guide part 410 is located within the cylindrical space defined by the arc surface of the top plate 411, which can reduce the movement space required for the air guide part 410 to rotate, and the walls of the casing 100 can be set closer to the air guide assembly 400, which can reduce the avoidance space and reduce the waste of the internal space of the casing 100.

[0102] like Figure 4As shown, when the air guide assembly 400 rotates out of the casing 100, the air inlet end of the air guide portion 410 is inclined with respect to the airflow direction. In order to allow the airflow blown out by the fan assembly 300 to completely enter the air guide assembly 400 and to better guide the airflow, other air guide structures may also be provided in the casing 100.

[0103] Please refer to Figure 3 and Figure 4 The housing 100 includes a second air guide surface 140. When the air guide portion 410 is located in the housing 100, the second air guide surface 140 is spaced apart from the air guide portion 410. When at least a portion of the air guide portion 410 rotates out of the housing 100, the second air guide surface 140 is used to guide air to flow into the air guide portion 410 along the second air guide surface 140. The second air guide surface 140 is a curved surface.

[0104] The second air guide surface 140 can be designed to be an arc surface. For example, the second air guide surface 140 can be set so that the center of the arc surface where the second air guide surface 140 is located coincides with the axis of the first rotating shaft 414. Then, the gap between the air guide assembly 400 and the second air guide surface 140 can be set to be very small, and the outer surface of the top plate 411 of the air guide portion 410 can rotate almost close to the second air guide surface 140, so that the second air guide surface 140 can guide almost all of the air entering the air outlet cavity to flow into the air guide assembly 400, reducing the airflow flowing out of the gap between the air guide assembly 400 and the second air guide surface 140, which can reduce airflow crosstalk and further reduce air outlet noise.

[0105] The air guide assembly 400 further includes a first driving device 420 , which is drivingly connected to the air guide portion 410 to drive the air guide portion 410 to rotate around the first rotating shaft 414 .

[0106] The first driving device 420 may have a first working mode, in which the first driving device 420 is used to drive the air guide 410 to rotate back and forth between the first position and the second position. At this time, by controlling the air guide 410 to rotate back and forth, the air guide 410 is continuously pitched about the first rotating shaft 414 relative to the first wall 130, thereby realizing the up and down air sweeping function of the air conditioner 10.

[0107] The first driving device 420 may also have a second working mode, in which the first driving device 420 is used to drive the air guide 410 to be in any position between the first position and the second position. At this time, the air guide 410 is maintained at a certain angle relative to the first wall 130, and the directional air supply function at the angle can be realized.

[0108] It is understandable that the air conditioner 10 may further include a control panel for controlling the operation of the entire air conditioner 10. Specifically, the control panel may store a control program of the first driving device 420 to control the first driving device 420 to operate in the first working mode or the second working mode according to user needs.

[0109] The first driving device 420 may include a first driving motor 421 and a transmission mechanism. The first driving motor 421 is indirectly connected to the first rotating shaft 414 via the transmission mechanism, so as to drive the first rotating shaft 414 to rotate through the rotation of the transmission mechanism.

[0110] Please refer to Figure 5 and Figure 7 The transmission mechanism includes a first transmission gear 422 and a second transmission gear 423. The first transmission gear 422 is connected to the output shaft of the first driving motor 421, the second transmission gear 423 is connected to the first rotating shaft 414, and the second transmission gear 423 is meshed with the first transmission gear 422.

[0111] It can be understood that the first transmission gear 422 serves as a driving gear and the second transmission gear 423 serves as a driven gear. When the first drive motor 421 is running, its output shaft drives the first transmission gear 422 to rotate, and at the same time, the first transmission gear 422 drives the second transmission gear 423 to mesh and rotate, thereby driving the first rotating shaft 414 to rotate and causing the air guide part 410 to rotate.

[0112] By adopting the above transmission mechanism, when the first transmission gear 422 and the second transmission gear 423 are configured with different numbers of teeth, the first transmission gear 422 and the second transmission gear 423 can output different speeds and torques. Then, by reasonably designing the gear ratio of the two gears, the first drive motor 421 can smoothly drive the air guide 410 to rotate when using a motor with a smaller power, thereby reducing production costs. Moreover, by setting gears for transmission, compared with direct drive by a motor, the rotation angle of the first rotating shaft 414 can be better fine-tuned, thereby facilitating users to more accurately adjust the rotation angle of the air guide 410.

[0113] In order to maintain the air guide assembly 400 at the first position or the second position, the air guide assembly 400 can be restrained by the first drive motor 421. Specifically, a brake mechanism can be configured inside the first drive motor 421. When the first drive motor 421 stops working, the brake mechanism can restrain the output shaft of the first drive motor 421 to keep the output shaft stationary. Therefore, when the air guide assembly 400 needs to be maintained at the first position, the second position, or any position between the first position and the second position, the air guide assembly 400 can be stably limited to the above position by stopping the first drive motor 421.

[0114] It can be understood that the air guide assembly 400 is limited to the above position by the first drive motor 421, and the overall weight of the air guide assembly 400 and the wind force applied to the air guide assembly 400 by the airflow will act on the first drive motor 421, causing the first drive motor 421 to bear a larger load. In order to reduce the load on the first drive motor 421, a limiting structure can also be set on the casing 100 and the air guide assembly 400 to achieve auxiliary limiting of the air guide assembly 400 through the limiting structure.

[0115] In one embodiment, the air conditioner 10 further includes a first limiting portion and a second limiting portion. The first limiting portion is used to limit the air guide assembly 400 to a first position when the air guide assembly 400 is in the housing 100. The second limiting portion is used to limit the air guide assembly 400 to a second position when the air guide assembly 400 rotates out of the housing 100.

[0116] For example, in one embodiment, please refer to Figure 8 , Figure 8 The schematic diagram of the air guide assembly of the air conditioner of the embodiment of the utility model is limited to the first position. The first limiting portion 150 can be set on the inner wall of the housing 100, for example, at the end position of the second air guide surface 140 away from the first opening 130a. When the air guide assembly 400 rotates from the second position to the first position, the end of the top plate 411 of the air guide 410 away from the air outlet 410b abuts against the first limiting portion 150. The first limiting portion 150 blocks the air guide 410 from continuing to rotate, and at the same time provides a bearing force to support the air guide 410, so that the air guide assembly 400 can be limited to the first position.

[0117] In one embodiment, please refer to Fig. 9 , Fig. 9 Schematic diagram of the air guide assembly of the air conditioner of the embodiment of the utility model being limited to the first position. The second limiting portion 160 can be arranged on the inner wall of the casing, for example, on two opposite inner side walls of the casing 100, and the first side plate 412 and the second side plate 413 of the air guide portion 410 can be provided with limiting convex portions 416. When the air guide assembly 400 rotates from the first position to the second position, the limiting convex portions 416 abut against the second limiting portion 160, and the second limiting portion 160 blocks the air guide portion 410 from continuing to rotate, so that the air guide portion 410 can be limited to the second position.

[0118] like Figure 3 As shown, the air guide assembly 400 further includes an air sweeping mechanism 430 , which is rotatably disposed at the air outlet 410 b of the air guide portion 410 , and a rotation axis of the air sweeping mechanism 430 is perpendicular to a rotation axis of the air guide portion 410 .

[0119] The wind guide portion 410 pitches and rotates relative to the first wall 130 around the first rotation axis 414 to achieve an upward and downward wind sweeping function, and the rotation axis of the wind sweeping mechanism 430 is perpendicular to the rotation axis of the wind guide portion 410, which means that the wind sweeping mechanism 430 can achieve leftward and rightward wind sweeping.

[0120] Then, the rotation of the air guide 410 can realize the upward and downward sweeping, and the rotation of the sweeping mechanism 430 can realize the left and right sweeping. That is to say, in this embodiment, the overall rotation of the air guide 410 cooperates with the rotation of the sweeping mechanism 430, and only one set of sweeping mechanisms 430 is set to realize the sweeping function in two directions. Compared with the air guide structure of the traditional air conditioner, one set of sweeping mechanisms is reduced, which can effectively reduce the resistance of the outlet air flow, improve the sweeping effect, and ensure the outlet wind speed and air volume. Moreover, the sweeping mechanism 430 is set at the air outlet 410b of the air guide 410, and there is no other structure blocking the side of the sweeping mechanism 430, which can further improve the sweeping effect of the sweeping direction corresponding to the sweeping mechanism 430, such as the left and right sweeping effect.

[0121] The support rod 415 can also be used as a connection and bearing component for setting the wind sweeping mechanism 430, so that the wind sweeping mechanism 430 can be installed in the wind guide portion 410. Exemplarily, the support rod 415 is provided with a first mounting portion, and the top plate 411 is provided with a second mounting portion, and the wind sweeping mechanism 430 is rotatably installed between the support rod 415 and the top plate 411 through the first mounting portion and the second mounting portion.

[0122] The first mounting portion includes a plurality of first mounting holes arranged at intervals along the length direction of the support rod 415, and the second mounting portion includes a plurality of second mounting holes, and the plurality of second mounting holes are arranged one-to-one with the plurality of first mounting holes. The wind sweeping mechanism 430 includes a plurality of wind sweeping blades 431, and the plurality of wind sweeping blades 431 are arranged along the length direction of the support rod 415, and each wind sweeping blade 431 is provided with a second rotating shaft, and the opposite ends of the second rotating shaft of each wind sweeping blade 431 are rotatably arranged in a group of first mounting holes and second mounting holes.

[0123] When the air conditioner 10 is not used for a long time, dust and lint outside the casing 100 easily enter the inside of the casing 100 through the air outlet 410b of the air guide portion 410, causing dust to accumulate on the air guide assembly 400 and the fan assembly 300, which will affect the air volume and wind speed when the air conditioner 10 is used next time, and increase the power consumption of the fan assembly 300. In order to prevent dust and lint from entering the casing 100 through the air outlet 410b, a damper can be provided at the air outlet 410b of the air guide portion 410 to close the air outlet 410b when the air conditioner 10 is not in use.

[0124] In one embodiment, when the air guide assembly 400 is in the first position, the air sweeping mechanism 430 can also close the air outlet 410b.

[0125] Specifically, when the air conditioner 10 is not in use, the air sweeping mechanism 430 is controlled to swing to close the air outlet 410b.

[0126] Then, when the air conditioner 10 is not in use, the air purge mechanism 430 can be controlled to rotate to close the air outlet 410b, which can prevent impurities such as dust and lint outside the casing 100 from entering the casing 100. In other words, the air purge mechanism 430 can not only be used to guide air, but also realize the function of a damper. There is no need to set up an additional damper, which can simplify the overall structure of the air guide assembly 400.

[0127] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
