Description

Technical Field

[0002] With the increasing improvement of people's living standards and the rapid development of the refrigeration industry, air conditioners have gradually become one of the indispensable electrical appliances in people's lives. In order to improve the heating and cooling effects of air conditioners and the user's comfort, some air conditioners with multi-angle air supply functions have emerged on the market. By adjusting the air supply direction of the air deflector, the multi-angle air supply function of the air conditioner is realized.

[0003] At present, some household air conditioner indoor units on the market use the form of large and small deflectors. The large deflector mainly plays a role in beauty when closed. It can only rotate around the rotation center between the air conditioner body, so the position of the large deflector is greatly restricted and it cannot participate in downward air guiding. When the air conditioner is heating, only the small deflector arranged inside the air duct is used for downward air guiding. However, since the position of the small deflector is relatively inside and the width is small, the downward air guiding effect during heating is not good, and the hot air cannot effectively reach the ground.

[0004] At present, another part of household air conditioner indoor units on the market also use an air guiding structure for setting the shaft positions of one air deflector and two air deflectors, which can automatically switch the position of the air deflector according to different operating states of the air conditioner, meeting the different requirements for air guiding directions during refrigeration and heating of the cooling and heating type air conditioner. However, at present, the air deflector driving mechanism for driving the air deflector to rotate around two shafts usually consists of multiple sets of connecting rods, rocker arms, hooks and other structures, with a complex structure and a high production cost.

[0005] In addition, in the solutions of other competing products that can flexibly control the position of the deflector, a rack and pinion motion mechanism is generally adopted, which not only has a high production cost but also has low reliability. Summary of the Utility Model

[0045] Hereinafter, exemplary embodiments of the present utility model will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present utility model can be fully conveyed to those skilled in the art.

[0046] Figure 1 It is a schematic structural diagram of an indoor unit of an air conditioner according to an embodiment of the present utility model, which shows the air deflector in the closed position. Figure 2 It is a schematic structural diagram of an indoor unit of an air conditioner according to another embodiment of the present utility model, which shows the air deflector in the maximum supply position. Figure 3 It is a schematic structural diagram of an indoor unit of an air conditioner according to still another embodiment of the present utility model, which shows the air deflector in the cold air upward blowing position. Figure 4 It is a schematic structural diagram of an indoor unit of an air conditioner according to another embodiment of the present utility model, which shows the air deflector in the hot air downward blowing position. Figure 5 It is a schematic structural diagram of an indoor unit of an air conditioner according to another embodiment of the present utility model, which shows the air deflector in the maximum hot air supply position. As Figures 1 to 5 shown, the present utility model provides an indoor unit 10 of an air conditioner. The indoor unit 10 of the air conditioner in this embodiment generally may include a housing 11.

[0047] As Figures 1 to 5 shown, an air inlet 12 is formed above the housing 11, and an air outlet 13 is formed below the front side of the housing 11. A heat exchanger 14, a blower 15 and an air duct 16 are sequentially arranged inside the housing 11 between the air inlet 12 and the air outlet 13.

[0048] As Figures 2 to 5 shown, under the drive of the blower 15, the indoor air flow 17 enters the indoor unit 10 of the air conditioner from the air inlet 12, exchanges heat with the heat exchanger 14, and then blows out from the air outlet 13 through the air duct 16 to deliver the heat-exchanged air flow 18 to the room.

[0049] In this embodiment, as Figure 1 shown, the air conditioner indoor unit 10 further includes a wind guiding structure 20 provided at the air outlet 13. The wind guiding structure 20 includes a wind guiding plate 100 and at least one driving component 200. The wind guiding plate 100 is rotatably provided at the air outlet 13 of the air conditioner indoor unit 10. The driving component 200 is at least partially connected to the wind guiding plate 100 and is configured to move the wind guiding plate 100 and adjust the air supply direction of the wind guiding plate 100.

[0050] Specifically, each driving component 200 includes a rotating arm 210, and the driving component 200 is configured to drive the rotating arm 210 to rotate around a first rotation center relative to the housing 11 of the air conditioner indoor unit 10 and drive the wind guiding plate 100 to rotate around a second rotation center relative to the rotating arm 210 to adjust the air supply direction of the wind guiding plate 100.

[0051] It should be noted that the air supply direction of the wind guiding plate 100 is different from the air outlet direction of the air outlet 13. The air supply direction of the wind guiding plate 100 refers to the flowing direction in which the heat-exchanged air flow 18 flows out from the air outlet 13 and blows into the room after being blocked and guided by the wind guiding plate 100 when the wind guiding plate 100 does not close the air outlet 13.

[0052] The wind guiding structure 20 of the embodiment of the present utility model includes a wind guiding plate 100 rotatably provided at the air outlet 13 of the air conditioner indoor unit 10 and at least one driving component 200 for driving the wind guiding plate 100 to rotate, realizing the adjustment of the air supply direction of the wind guiding plate 100. The driving component 200 of the embodiment of the present utility model includes a rotating arm 210, and the driving component 200 is configured to drive the rotating arm 210 to rotate around a first rotation center relative to the housing 11 of the air conditioner indoor unit 10 and drive the wind guiding plate 100 to rotate around a second rotation center relative to the rotating arm 210 to adjust the air supply direction of the wind guiding plate 100, realizing the construction of the wind guiding plate form with a double rotation center of the wind guiding plate 100 only by using a simple structure, simplifying the angle adjustment structure of the wind guiding plate 100, avoiding the problem of high cost caused by a complex structure while realizing multi-angle air supply directions, and effectively reducing the production cost of the wind guiding component.

[0053] In some embodiments, the wind guiding structure 20 may include one driving component 200. In a specific embodiment, one end of the two ends of the wind guiding plate 100 in its length direction is connected to one driving component 200, and the other end of the two ends of the wind guiding plate 100 in its length direction is movably connected to the housing 11 via a transmission rod (not shown in the figure). In another specific embodiment, the middle part of the wind guiding plate 100 is connected to one driving component 200, and the two ends of the wind guiding plate 100 in its length direction are respectively movably connected to the housing 11 via a transmission rod (not shown in the figure).

[0054] Using the above structure, the air guiding structure 20 of this embodiment only uses one driving component 200 to provide the driving force for adjusting the air supply direction of the air guiding plate 100, reducing energy loss and thus reducing the usage cost of the air conditioner.

[0055] In some embodiments, the air guiding structure 20 may further include two driving components 200, and both ends of the air guiding plate 100 in its length direction are respectively connected to one driving component 200. When adjusting the air supply direction of the air guiding plate 100, the two driving components 200 are synchronously controlled to synchronously adjust the left and right ends of the air guiding plate 100.

[0056] Using the above structure, the air guiding structure 20 of this embodiment utilizes two driving components 200 to provide the driving force for adjusting the air supply direction of the air guiding plate 100, and at the same time provides supporting forces for both ends of the air guiding plate 100 in the length direction, realizing stable adjustment of the position of the air guiding plate 100, improving the structural reliability and stability, and at the same time improving the accuracy of adjusting the air supply direction of the air guiding plate 100.

[0057] In some embodiments, the air guiding structure 20 may further include a plurality of driving components 200, and the plurality of driving components 200 are arranged at intervals along the length direction of the air guiding plate 100 and are all connected to the air guiding plate 100 to provide stable supporting forces at various positions in the length direction of the air guiding plate 100, thereby further improving the structural reliability and stability, and further improving the accuracy of adjusting the air supply direction of the air guiding plate 100.

[0058] In some embodiments, as Figures 1 to 5 shown, one end of the swing arm 210 is pivotally connected to the housing 11 of the indoor unit 10 of the air conditioner around the first rotation center O1. Thus, the swing arm 210 can rotate around the first rotation center O1 relative to the housing 11 of the indoor unit 10 of the air conditioner, so as to drive the air guiding plate 100 to rotate around the first rotation center O1 relative to the housing 11 of the indoor unit 10 of the air conditioner when there is no relative movement between the air guiding plate 100 and the swing arm 210. The air guiding plate 100 is pivotally connected to the end of the swing arm 210 far away from the indoor unit 10 of the air conditioner around the second rotation center O2. Thus, when there is no relative movement between the swing arm 210 and the housing 11 of the indoor unit 10 of the air conditioner, the air guiding plate 100 can rotate relative to the rotation of the indoor unit 10 of the air conditioner around the second rotation center O2, thereby realizing the construction of the air guiding plate form with a double rotation center for the air guiding plate 100.

[0059] One end of the swing arm 210 in the air guiding structure 20 of the embodiment of the present utility model is pivotally connected to the housing 11 of the air conditioner indoor unit 10 around the first rotation center O1, and the air guiding plate 100 is pivotally connected to the end of the swing arm 210 away from the air conditioner indoor unit 10 around the second rotation center O2, realizing the stable construction of the air guiding structure 20. A rotation center is provided at each of the two ends of the swing arm 210, and the construction of the air guiding plate in the form of a double rotation center can be realized without relying on the transmission between multiple sets of transmission structures, ensuring the structural reliability and stability of the air guiding structure 20. In addition, the driving component 200 of the embodiment of the present utility model has a simple structure, avoiding the mutual interference between complex transmission structures, reducing the problems of large use losses and high maintenance costs caused by wear due to collisions between components inside the driving component 200, and thus reducing the use cost of the air guiding component.

[0060] In some embodiments, as Figures 1 to 5 shown, the driving component 200 further includes a first driving motor (not shown in the figure) and a second driving motor (not shown in the figure). The first driving motor is disposed at one end of the swing arm 210 close to the housing 11 and is used to drive the swing arm 210 to rotate around the first rotation center O1 relative to the housing 11 of the air conditioner indoor unit 10, so as to drive the air guiding plate 100 to rotate around the first rotation center O1 relative to the housing 11. The second driving motor is disposed at one end of the swing arm 210 close to the air guiding plate 100 and is used to drive the air guiding plate 100 to rotate around the second rotation center O2 relative to the swing arm 210.

[0061] The driving component 200 of the embodiment of the present utility model includes a first driving motor and a second driving motor that can be respectively controlled to operate. The first driving motor is disposed at one end of the swing arm 210 close to the housing 11 and is used to drive the swing arm 210 to rotate around the first rotation center O1 relative to the housing 11 of the air conditioner indoor unit 10, so as to drive the air guiding plate 100 to rotate around the first rotation center O1 relative to the housing 11. The second driving motor is disposed at one end of the swing arm 210 close to the air guiding plate 100 and is used to drive the air guiding plate 100 to rotate around the second rotation center O2 relative to the swing arm 210, realizing the separate control of the rotation angle of the air guiding plate 100 around the first rotation center O1 and the rotation angle around the second rotation center O2, and ensuring the accuracy of adjusting the air supply angle of the air guiding structure 20.

[0062] It should be noted that when the air guiding structure 20 has multiple driving components 200, the air guiding structure 20 of this embodiment has multiple first driving motors and multiple second driving motors. All the first driving motors are synchronously controlled and synchronously adjust the position of the upper side of the air guiding plate 100, and all the second driving motors are synchronously controlled and synchronously adjust the position of the lower side of the air guiding plate 100 to improve the stability of the movement of the air guiding plate 100.

[0063] In some embodiments, as Figures 1 to 5 shown, the swing arm 210 is a strip-shaped structure formed by connecting a front arm 211 close to the air deflector 100 and a rear arm 212 close to the housing 11. Specifically, the swing arm 210 is an integral part made by an integral molding process. With the above structure, the drive assembly 200 of the embodiment of the present utility model has a stable structure, and the air deflector 100 can be movably connected to the housing 11 of the air conditioner indoor unit 10 by means of the swing arm 210, ensuring the reliability and stability of the overall structure.

[0064] Furthermore, as Figures 1 to 5 shown, the interior of the front arm 211 is hollow to form an installation cavity 213. The second drive motor can be installed in the installation cavity 213. The air deflector 100 is in transmission connection with the output shaft of the second drive motor. Specifically, the second drive motor is fixedly installed in the installation cavity 213, and the output shaft of the second drive motor extends out of the installation cavity 213 through a through hole 2111 opened on the front arm 211 and is connected to the air deflector 100 to drive the air deflector 100 to rotate relative to the swing arm 210 around the second rotation center O2. That is to say, as Figures 1 to 5 shown, the second rotation center O2 is located in the middle of the front end of the front arm 211, that is, at the axial center position of the output shaft of the second drive motor.

[0065] In the drive assembly 200 of this embodiment, the second drive motor is installed in the installation cavity 213, which realizes the protection of the second drive motor, ensures the reliability and stability of the structure while simplifying the process, avoids the interference between the second drive motor and other components during the rotation of the swing arm 210, reduces the wear caused by the collision between the components inside the air deflector assembly, and thus further improves the reliability and stability of the structure.

[0066] In some embodiments, the first drive motor can be installed on the housing 11. The rear arm 212 is in transmission connection with the output shaft of the first drive motor. Specifically, the second drive motor is fixedly installed on the housing 11, and the output shaft of the first drive motor is connected to a transmission structure 2121 provided on the rear arm 212 to drive the swing arm 210 to rotate relative to the housing 11 of the air conditioner indoor unit 10 around the first rotation center O1. That is to say, as Figures 1 to 5 shown, the first rotation center O1 is located in the middle of the transmission structure 2121 provided on the rear arm 212, that is, at the axial center position of the output shaft of the first drive motor.

[0067] In some embodiments, as Figure 1As shown, the front arm 211 can be bent downward from the end of the rear arm 212 away from the housing 11, and the bending angle α of the downward bending of the front arm 211 is between 30° and 150°. Thus, a certain space is left between the lower part of the swivel arm 210 and the lower structure of the housing 11, avoiding collision between the swivel arm 210 and the lower structure of the housing 11 when the swivel arm 210 rotates downward relative to the housing 11, thereby increasing the limit rotation angle of the swivel arm 210 relative to the housing 11 and further ensuring the structural reliability and stability of the blade assembly.

[0068] In some embodiments, as Figures 1 to 5 shown, the first drive motor is disposed at a position on the rear side edge of the housing 11 near the air outlet 13, so that the rear end of the rear arm 212 can be rotatably mounted on the housing 11 at a position near the rear side edge of the air outlet 13 via the first drive motor. Thus, the first rotation center O1 is disposed adjacent to the rear side edge of the air outlet 13.

[0069] Thus, when the swivel arm 210 rotates relative to the housing 11 of the air conditioner indoor unit 10 about the first rotation center O1 and there is no relative movement between the air deflector 100 and the swivel arm 210, the air deflector 100 can rotate around the first rotation center O1 relative to the air outlet 13 over a large range, thereby adjusting the air guiding position of the air deflector 100.

[0070] In some embodiments, as Figures 1 to 5 shown, the air deflector 100 has an inner surface 110 facing the air outlet 13 and being concave-arc-shaped. That is to say, the inner surface 110 is the air guiding surface of the air deflector 100. The air flow 18 after heat exchange of the air guiding surface flows out from the air outlet 13 and can be blown into the room under the guidance of the inner surface 110 of the air deflector 100. The projection of the second rotation center O2 in the direction perpendicular to the inner surface is located at the middle of the inner surface.

[0071] Thus, when the air deflector 100 rotates relative to the swivel arm 210 about the second rotation center O2 and there is no relative movement between the swivel arm 210 and the housing 11 of the air conditioner indoor unit 10, the air deflector 100 can rotate around the second rotation center O2 within a small range in the air outlet path of the air outlet 13, thereby adjusting the air supply direction of the air deflector 100.

[0072] Furthermore, the air deflector 100 has a closed position and a plurality of air guiding positions under the drive of the first drive motor and / or the second drive motor. As Figure 1As shown, the air deflector 100 closes the air outlet 13. At this time, the air deflector 100 is in the closed position. The multiple air guiding positions include a front air guiding position where the front side of the air outlet 13 is open and a lower air guiding position where the front side of the air outlet 13 is blocked. When the air conditioner is cooling, the front blowing mode can be selected to make the air deflector 100 in the front air guiding position, so that the cold air can be sent farther, and then gradually sink after reaching a distance, forming a shower cooling effect. When the air conditioner is heating, the lower blowing mode can be selected to make the hot air easier to reach the ground, so as to achieve a carpet-like air supply effect, avoiding the situation that the hot air cannot reach the ground due to its small density, and enabling the bottom space of the room to be heated.

[0073] In some embodiments, the air guiding position of the air deflector 100 and the air supply mode of the air conditioner are set in one-to-one correspondence. Specifically, the front blowing mode can include a maximum air supply mode and a cooling upward blowing mode, and the lower blowing mode can include a heating downward blowing mode and a maximum heating mode. Thus, the air guiding position of the air deflector 100 can reach the maximum air supply position, the cold air upward blowing position, the hot air downward blowing position, and the maximum hot air supply position respectively under the drive of the first drive motor and / or the second drive motor.

[0074] In some embodiments, the first drive motor and the second drive motor are configured to operate under the remote control of the user. Specifically, different air supply modes can be selected when the air conditioner indoor unit 10 is cooling and heating. When the user switches the air supply mode through the remote control, the air guiding structure 20 can automatically adjust to the corresponding operating state, and the first drive motor and the second drive motor can be controlled to operate, so as to realize the automatic adjustment of the air guiding position and the air supply angle of the air deflector 100, making the air supply direction of the air deflector 100 more in line with the special needs of cooling and heating, and the design is very ingenious. The following will describe Figures 2 to 5 the multiple air guiding positions of the air deflector 100.

[0075] As Figure 2 shown, when the air conditioner indoor unit 10 selects the maximum air supply mode, the first drive motor can drive the rotating arm 210 to rotate downward by a first preset angle around the first rotation center O1 relative to the housing 11 of the air conditioner indoor unit 10, and the second drive motor can drive the air deflector 100 to rotate downward by a first preset rotation angle around the second rotation center O2 relative to the rotating arm 210, so that the air deflector 100 completely opens the air outlet 13, and the rear edge of the air deflector 100 abuts against the housing 11 behind the air outlet 13. At this time, the air deflector 100 reaches the maximum air supply position, and the air conditioner indoor unit 10 supplies air forward and downward.

[0076] Specifically, both the first preset angle and the first preset rotation angle can be set according to pre-experiments and stored inside the air conditioner indoor unit 10.

[0084] In some embodiments, the air guiding structure 20 of the present invention can be used for a wall-mounted air conditioner indoor unit or a floor-standing air conditioner indoor unit. In the embodiment where the air guiding structure 20 is used for a wall-mounted air conditioner indoor unit, the length direction of the air outlet 13 of the air conditioner indoor unit 10 and the length direction of the air deflector 100 can both be in the horizontal direction.

As Figure 6 shown, the air conditioner 1 generally can include the air conditioner indoor unit 10 of any of the above embodiments.

[0086] The air conditioner 1 according to the embodiment of the present utility model realizes the adjustment of the air supply direction of the air deflector 100 by providing an air guiding structure 20 composed of an air deflector 100 rotatably arranged at the air outlet 13 of the indoor unit 10 of the air conditioner and at least one driving component 200 for driving the air deflector 100 to rotate. The driving component 200 of the embodiment of the present utility model includes a rotating arm 210, and the driving component 200 is configured to drive the rotating arm 210 to rotate around a first rotation center O1 relative to the housing 11 of the indoor unit 10 of the air conditioner and drive the air deflector 100 to rotate around a second rotation center O2 relative to the rotating arm 210, so as to adjust the air supply direction of the air deflector 100, realizing the construction of the air deflector 100 with a double rotation center only by using a simple structure, simplifying the angle adjustment structure of the air deflector 100, while realizing the flexible adjustment of the air supply direction, avoiding the problem of high cost caused by complex structures, and effectively reducing the production cost of the air guiding component.

[0087] Further, one end of the rotating arm 210 in the air guiding structure 20 of the air conditioner 1 according to the embodiment of the present utility model is pivotally connected to the housing 11 of the indoor unit 10 of the air conditioner around the first rotation center O1, and the air deflector 100 is pivotally connected to the end of the rotating arm 210 away from the indoor unit 10 of the air conditioner around the second rotation center O2, realizing the stable construction of the air guiding structure 20.

In addition, the structure of the driving component 200 of the present utility model is simple, avoiding the mutual interference between complex transmission structures, reducing the problems of large use loss and high maintenance cost caused by the collision and wear between the components inside the driving component 200, and thus reducing the use cost of the air guiding component.

[0088] Furthermore, the driving component 200 of the air conditioner 1 according to the embodiment of the present utility model includes a first driving motor and a second driving motor that can be respectively controlled to operate. The first driving motor is arranged at one end of the rotating arm 210 close to the housing 11 and is used to drive the rotating arm 210 to rotate around the first rotation center O1 relative to the housing 11 of the indoor unit 10 of the air conditioner, so as to drive the air deflector 100 to rotate around the first rotation center O1 relative to the housing 11. The second driving motor is arranged at one end of the rotating arm 210 close to the air deflector 100 and is used to drive the air deflector 100 to rotate around the second rotation center O2 relative to the rotating arm 210, realizing the separate control of the rotation angle of the air deflector 100 around the first rotation center O1 and the rotation angle around the second rotation center O2, and ensuring the accuracy of adjusting the air supply angle of the air guiding structure 20.
