[0001] The utility model relates to a refrigeration equipment more particularly, relate to an air conditioner and air deflector assembly thereof. BACKGROUND

[0002] At present, the air conditioner includes a deflector and a driving motor. The driving motor is arranged at one end of the deflector and is used to drive the deflector to rotate. The deflector is usually supported by the middle part of the panel or the chassis of the air conditioner to limit the deflector when the deflector is opened and closed. Since the driving motor applies a torque to one end of the deflector and the rigidity of the deflector is insufficient, the deflector will be twisted when the deflector is limited, which further causes inaccurate physical limitation of the deflector. Inaccurate physical limitation of the deflector will further cause inaccurate judgment of the current position of the deflector by the air conditioner, and the subsequent deflector cannot be accurately reset, so that the set air supply angle of the air conditioner deviates from the actual air supply angle, affecting the comfort.

[0039] In order to make the purpose, technical scheme and advantages of the utility model more clear and apparent, the following will combine the drawings to explain the embodiments of the utility model in detail.

[0040] As Figure 1 ,​​​2 As shown in the drawings, Figure 1 , 2 The structure of a wind guide assembly 100 of an air conditioner according to an embodiment of the present application is shown. The wind guide assembly 100 includes a base plate 1, a driving motor 3 and a wind guide plate 2. The driving motor 3 and the wind guide plate 2 are both arranged on the base plate 1.

[0041] As shown in the drawings, Figure 3 , 4 The base plate 1 includes a base plate body 11 and a mounting portion 12. The base plate body 11 is provided with an air outlet 10. The base plate body 11 can be configured as a straight strip structure, and the air outlet 10 is configured as a straight strip opening, extending from one end of the base plate body 11 to the other end. The air outlet 10 is used for air supply. The mounting portion 12 can be configured as a plate structure. The mounting portion 12 is arranged at one end of the base plate body 11, and the mounting portion 12 is perpendicular to the extension direction of the base plate body 11. The mounting portion 12 is located at the front side of the base plate body 11. The side of the mounting portion 12 close to the air outlet 10 is provided with a first limiting portion 13.

[0042] The driving motor 3 includes a housing 31 and a main shaft (not shown in the drawings). The main shaft extends from the housing 31. The main shaft can be rotated in both forward and reverse directions. The housing 31 is connected to the mounting portion 12. The housing 31 can be screw-connected to the mounting portion 12. The main shaft of the driving motor 3 can be arranged perpendicular to the mounting portion 12, and the main shaft can extend towards the side of the mounting portion 12 close to the air outlet 10.

[0043] As shown in the drawings, Figure 5 , 6 The wind guide plate 2 includes a plate body 21, a connecting portion 22 and a second limiting portion 23. The plate body 21 is configured as a straight strip plate structure. The cross section of the plate body 21 can be arc-shaped. The plate body 21 is arranged at the front end of the air outlet 10 of the base plate body 11. The extension direction of the plate body 21 is the same as the extension direction of the cross section of the air outlet 10. The connecting portion 22 is arranged at one end of the plate body 21. The connecting portion 22 can be configured as a flat bracket structure. The connecting portion 22 is in transmission connection with the main shaft of the driving motor 3. When the main shaft of the driving motor 3 rotates, it can drive the whole wind guide plate 2 to rotate around the main shaft. The second limiting portion 23 is arranged on the connecting portion 22. The second limiting portion 23 is arranged at the side of the connecting portion 22 close to the mounting portion 12 of the base plate 1. The first limiting portion 13 is arranged at the side of the mounting portion 12 close to the second limiting portion 23. The first limiting portion 13 and the second limiting portion 23 cooperate to limit the rotation amplitude of the wind guide plate 2.

[0044] In the technical solution of the present application, the driving motor 3 applies torque to drive the air deflector 2 to rotate, and the second limiting part 23 on the air deflector 2 cooperates with the first limiting part 13 on the base 1 to limit the rotation of the air deflector 2. Since the main shaft of the driving motor 3 is connected to the connecting part 22 of the air deflector 2, the second limiting part 23 of the air deflector 2 is also arranged on the connecting part 22, and when the air deflector 2 is in the limiting position, the pressure applied by the first limiting part 13 and the torque applied by the driving motor 3 are counteracted at the connecting part 22 of the air deflector 2, and the force-bearing parts of the air deflector 2 are close to each other, which does not cause the plate body 21 of the air deflector 2 to be twisted and deformed, and the limiting of the air deflector 2 is more accurate.

[0045] In an illustrative embodiment, as shown in Figure 4 , the first limiting part 13 on the base 1 is arranged as a groove, and the opening of the groove faces the connecting part 22. The groove can be arranged close to the rotating shaft of the driving motor 3.

[0046] As shown in Figure 6 , the second limiting part 23 of the air deflector 2 is arranged as a protrusion protruding towards the mounting part 12 of the base 1, and the protrusion is inserted into the groove. The volume of the groove is much larger than the volume of the protrusion, and the protrusion can move in the groove as the air deflector 2 rotates.

[0047] As shown in Figure 2 , when the protrusion on the air deflector 2 abuts against the side wall of the groove on the base 1 as the air deflector 2 rotates, the air deflector 2 cannot continue to rotate, thereby limiting the air deflector 2.

[0048] In this way, the first limiting part 13 is arranged as a groove, and the second limiting part 23 is arranged as a protrusion, and the cooperation of the groove and the protrusion can limit the air deflector 2. In particular, the air deflector 2 can rotate in two directions, and the protrusion can limit the rotation of the air deflector 2 in two directions by abutting against the two opposite side walls of the groove.

[0049] In an illustrative embodiment, as shown in Figure 4 , the first limiting part 13 is arranged as a circular-arc-shaped slot, and the extension direction of the slot is the circumferential direction of the main shaft of the driving motor 3.

[0050] As shown in Figure 7 , 8 , when the second limiting part 23 rotates to one end of the first limiting part 13 and abuts against the side wall of the one end, the air deflector 2 is in the first limiting position, and the air deflector 2 can guide the airflow output by the air outlet 10 downward; as shown in Figure 10 , 11As shown, when the second limiting part 23 rotates to the other end of the first limiting part 13 and abuts against the side wall of this end, the air guide plate 2 is in the second limiting position. When the air guide plate 2 is in the second limiting position, it can guide the airflow output from the air outlet 10 forward. The range of angles that the air guide plate 2 can rotate is the same as the arc of the first limiting part 13.

[0051] In some embodiments, such as Figure 7 , 8 As shown, the drive motor 3 first drives the air guide plate 2 to the first limit position, and then, as... Figure 9 As shown, the air guide plate 2 is then driven to reverse the first preset angle so that the air guide plate 2 reaches the closed position, making the air guide plate 2 flush with the outer surface of the air conditioner's casing.

[0052] In some embodiments, such as Figure 10 , 11 As shown, the drive motor 3 first drives the air guide plate 2 to the second limit position, and then, as... Figure 9 As shown, the air guide plate 2 is then driven to reverse the second preset angle so that it reaches the closed position, making it flush with the outer surface of the air conditioner's casing. The second preset angle can be 90°.

[0053] In some embodiments, the drive motor 3 first drives the air guide plate 2 to a first limit position. At the first limit position, the air guide plate 2 is flush with the outer surface of the air conditioner casing and is in a closed state.

[0054] In one illustrative embodiment, such as Figure 6 As shown, the second limiting part 23 is configured as a cylindrical protrusion. The axis of the second limiting part 23 is parallel to the axis of the main shaft of the drive motor 3.

[0055] The cylindrical second limiting part 23 slides more smoothly within the arc-shaped groove.

[0056] In one illustrative embodiment, such as Figure 4 As shown, the air guide assembly 100 also includes a bushing 4. The bushing 4 has a sleeve-like structure. The bushing 4 is sleeved on the main shaft of the drive motor 3. The bushing 4 and the main shaft of the drive motor 3 can be either an interference fit or a keyed connection. The bushing 4 has a straight cylindrical shape. The extending direction of the bushing 4 is the same as the extending direction of the main shaft of the drive motor 3.

[0057] like Figure 6 As shown, a shaft hole 24 is provided on the connecting part 22 of the air guide plate 2. The shaft hole 24 can be a through hole or a blind hole. The end of the bushing 4 facing away from the drive motor 3 is inserted into the shaft hole 24. The cross-sectional structure of the shaft hole 24 of the connecting part 22 is polygonal, that is, the shaft hole 24 is a polygonal hole. The cross-section of the bushing 4 is the same as the cross-section of the shaft hole 24.

[0058] In this way, the connecting portion 22 of the air deflector 2 and the shaft sleeve 4 can be directly connected by insertion, which facilitates assembly. Meanwhile, since the shaft hole 24 is a polygonal hole and the cross section of the shaft sleeve 4 is also a polygonal structure, the shaft sleeve 4 and the shaft hole 24 are connected by a shape surface, and the connecting portion 22 and the shaft sleeve 4 can transmit a larger torque.

[0059] In an illustrative embodiment, the cross section of the shaft sleeve 4 and the cross section of the shaft hole 24 are both regular polygons, and the number of sides of the regular polygon is 4-8.

[0060] Since the cross section of the shaft sleeve 4 and the cross section of the shaft hole 24 are both regular polygons, the shaft sleeve 4 does not need to be aligned at a specific angle when being inserted into the shaft hole 24, which makes assembly simpler. Meanwhile, the number of sides of the regular polygon is 4-8, and the connecting portion 22 and the shaft sleeve 4 can transmit a larger torque.

[0061] In an illustrative embodiment, as shown in Figure 2 , 4 The mounting portion 12 is provided with a through hole 14 which vertically penetrates the mounting portion 12. The through hole 14 can be a circular hole. The housing 31 of the driving motor 3 is arranged on the side of the mounting portion 12 which is away from the air deflector 2, and the mounting portion 12 is located between the housing 31 and the air deflector 2. The main shaft of the driving motor 3 extends into the through hole 14 of the mounting portion 12 and is coaxially arranged with the through hole 14. The shaft sleeve 4 is arranged in the through hole 14 of the mounting portion 12.

[0062] Arranging the driving motor 3 on the side of the mounting portion 12 which is away from the air deflector 2 can avoid the driving motor 3 occupying the space between the mounting portion 12 and the air deflector 2, so that the gap between the air deflector 2 and the mounting portion 12 can be arranged smaller, and air leakage between the air deflector 2 and the mounting portion 12 is less likely to occur.

[0063] In an illustrative embodiment, the first limiting portion 13 is arranged around the through hole 14 of the mounting portion 12.

[0064] In this way, the first limiting portion 13 is close to the through hole 14 of the mounting portion 12, and the first limiting portion 13 is close to the shaft sleeve 4, which can further reduce the distance between the stress receiving portions of the air deflector 2, so that the air deflector 2 is less likely to be twisted and deformed, and the limiting of the air deflector 2 is more accurate.

[0065] In another illustrative embodiment, the second limiting portion on the air deflector 2 is a groove, and the opening of the groove faces the connecting portion 22. The groove can be arranged close to the rotating shaft of the driving motor 3.

[0066] The first limiting part on the chassis 1 is a protrusion protruding to the side of the connecting part 22 of the air deflector 2, which is inserted into the groove.

[0067] When the air deflector 2 is rotated to the side wall of the groove on the protrusion on the chassis 1, the air deflector 2 cannot be continuously rotated, thereby limiting the air deflector 2.

[0068] In this way, the second limiting part is a groove, and the first limiting part is a protrusion, and the limiting of the air deflector 2 can be realized by the cooperation of the groove and the protrusion.

[0069] In this embodiment, the second limiting part is a circular-arc-shaped slot, and the extension direction of the slot is the circumferential direction of the main shaft of the driving motor 3.

[0070] When the first limiting part is rotated to one end of the second limiting part and abuts against the side wall of the end, the air deflector 2 is located at the first limiting position; when the first limiting part is rotated to the other end of the second limiting part and abuts against the side wall of the end, the air deflector 2 is located at the second limiting position.

[0071] In this embodiment, the first limiting part is a cylindrical protrusion, and the axis of the first limiting part is parallel to the axis of the main shaft of the driving motor 3.

[0072] The cylindrical first limiting part slides in the circular-arc-shaped groove, which is more smooth.

[0073] The application further provides an air conditioner comprising the air deflector assembly 100.
