[0048] In the related art, the traditional air conditioner filter grip plate is constructed as a rectangular plate. In order to ensure the convenience of filter disassembly and assembly, the filter grip plate needs to be provided with a grip groove of a certain width, and then the width of the filter grip plate needs to be widened as a whole, thereby reducing the area of ​​the back panel air inlet, reducing the gas flow in the air duct, seriously affecting the operation effect of the air conditioner, and may even cause duct surge.

[0049] Reference below Figure 1-Figure 13 A back plate assembly for an air conditioner according to an embodiment of the utility model is described.

[0050] According to the utility model, a back panel assembly 200 for an air conditioner comprises: a back panel body 1 and a hand plate 2, wherein an air inlet 101 is formed on the back panel body 1, a first groove 11 arranged at at least a portion of the periphery of the air inlet 101 and a second groove 12 connected to the first groove 11 are formed on the back panel body 1, the second groove 12 is arranged on a side of the first groove 11 away from the air inlet 101 and the width of the second groove 12 is greater than the width of the first groove 11; a hand groove 21 is formed on the hand plate 2 and cooperates with the first groove 11 and the second groove 12 respectively.

[0051] In some specific embodiments, the back panel assembly 200 is mainly composed of a back panel body 1 and a hand plate 2. The back panel body 1 is used to protect the internal components of the air conditioner 100 and can also play a role in heat insulation. An air inlet 101 is formed on the back panel body 1. The air outside the air conditioner 100 flows into the interior of the air conditioner 100 through the air inlet 101. A first groove 11 and a second groove 12 that are connected to each other are formed on the back panel body 1.

The width of the second groove 12 is greater than the width of the first groove 11. A hand groove 21 is formed on the hand plate 2, and the hand groove 21 is accommodated in the first In the second groove 12, the rest of the hand buckle plate 2 is received in the first groove 11. Compared with the conventional technology in which the hand buckle plate 2 receiving groove is designed as a single rectangular groove in order to match the shape of the hand buckle plate 2, when the present application needs to meet the large size of the hand buckle groove 21, the present application only needs to widen the second groove 12 in the direction away from the air inlet 101, and the first groove 11 can remain unchanged. There is no need to widen the first groove 11 and the second groove 12 as a whole along the width direction as in the conventional technology. The design method of the present application can meet the width of the hand buckle groove 21 without occupying the air inlet area of ​​the air inlet 101, thereby ensuring the air flow rate in the air duct and improving the stability and reliability of the air conditioner 100 during operation.

Fig.13 It can be clearly seen that the width of the second slot 12 is greater than that of the first slot 11, and the hand slot 21 is accommodated in the second slot 12. When the larger hand slot 21 needs to be met, the second slot 12 can be widened alone in the direction away from the air inlet 101, and the first slot 11 remains unchanged. There is no need to widen the first slot 11 and the second slot 12 as a whole, which not only meets the width of the hand slot 21, but also does not occupy the air inlet area of ​​the air inlet 101, thereby ensuring the air flow rate in the air duct and improving the stability and reliability of the air conditioner 100 during operation.

[0053] According to some embodiments of the utility model, the hand buckle plate 2 includes: a main body portion 22 and a matching portion 23, wherein a hand buckle groove 21 is formed on the main body portion 22 and is accommodated in the second groove 12; the matching portion 23 is connected to the main body portion 22 and is suitable for matching with the first groove 11, and the matching portion 23 is arranged in the first groove 11; wherein the width of the matching portion 23 is d1, the width of the main body portion 22 is d2, and satisfies: d1<d2.

[0054] In some specific embodiments, the hand plate 2 is composed of a main body 22 and a matching portion 23, and the main body 22 is composed of a hand groove 21 and an extension portion. A hand groove 21 is formed at the center of the main body 22, and the hand groove 21 is accommodated in the second groove 12. The extension portion is arranged around a portion of the outer periphery of the hand groove 21, and the matching portion 23 is connected to the main body 22. The main body 22 is arranged on a side of the matching portion 23 away from the air inlet 101, and the matching portion 23 is accommodated in the first groove 11. The width of the matching portion 23 is d1, and the width of the main body 22 is d2, wherein d1 and d2 satisfy the following relationship: d1<d2. In order to ensure the width of the hand groove 21, the present application can widen the main body 22 alone in the direction away from the air inlet 101, and the matching portion 23 remains unchanged, thereby eliminating the need to occupy the air inlet area of ​​the air inlet 101, ensuring the air flow rate in the air duct, and improving the stability and reliability of the air conditioner 100 during operation.

[0055] According to some embodiments of the present invention, the length of the hand buckle groove is c, and satisfies: c≥80mm.

[0056] In some specific embodiments, the length of the hand snap groove 21 is c, where c satisfies: c≥80 mm, that is, the minimum length of the hand snap groove in the present application is 80 mm, to meet the hand sizes of different users. The user can easily insert his hand into the hand snap groove 21 to remove the hand snap plate 2 from the back plate, reducing the difficulty of disassembling the hand snap plate 2.

[0057] According to some embodiments of the utility model, a first wall 111 is formed on the side of the first groove 11 close to the air inlet 101, and a second wall 121 opposite to the first wall 111 is formed on the side of the second groove 12 away from the air inlet 101; wherein a first clamping portion and a second clamping portion are respectively formed on the first wall 111 and the second wall 121, the first clamping portion is suitable for clamping with the matching portion 23, and the second clamping portion is suitable for clamping with the main body portion 22.

[0058] In some specific embodiments, the first groove 11 and the second groove 12 are respectively formed with a first wall 111 and a second wall 121 which are arranged opposite to each other. The first wall 111 is arranged near the air inlet 101, and the second wall 121 is arranged away from the air inlet 101. The hand clamp 2 is arranged between the first wall 111 and the second wall 121. A first clamping portion is formed on the first wall 111, and a second clamping portion is formed on the second wall 121. The first clamping portion is clamped and connected with the matching portion 23 to limit the movement of the hand clamp 2 relative to the first groove 11 and the second groove 12. The second clamping portion and at least part of the outer wall of the main body 22 abut against each other in the thickness direction, thereby limiting the movement of the main body 22 along the thickness direction of the back plate body 1, thereby fixing the hand clamp 2 in the first groove 11 and the second groove 12, thereby improving the stability and reliability of the hand clamp 2 in the first groove 11 and the second groove 12.

[0059] According to some embodiments of the utility model, the first clamping portion is constructed as a clamping rib 15 extending along the edge of the air inlet 101, and the clamping rib 15 is inclined toward the bottom of the first groove 11 in a direction close to the second wall 121; a clamping groove 16 suitable for cooperating with the clamping rib 15 is formed on the mating portion 23.

[0060] In some specific embodiments, the first clamping portion is constructed as a clamping rib 15 arranged at the edge of the air inlet 101, and a clamping groove 16 is formed on the mating portion 23. The clamping rib 15 can extend into the clamping groove 16, and the clamping rib 15 extends along the height direction of the back panel body 1. The clamping rib 15 is inclined relative to the second wall 121, and the clamping rib 15 is inclined toward the bottom wall of the first groove 11 in the direction close to the second wall 121. When the clamping rib 15 is inserted into the clamping groove 16, due to the inclined setting of the clamping rib 15, the edge of the clamping rib 15 will first contact the edge of the clamping groove 16, thereby reducing the contact area between the clamping rib 15 and the clamping groove 16, thereby reducing the friction between the clamping rib 15 and the clamping groove 16, making it easier to insert the clamping rib 15 into the clamping groove 16, thereby reducing the difficulty of assembling the hand buckle plate 2 and the back panel body 1.

[0061] According to some embodiments of the present invention, the clamping groove 16 has a first limiting wall 161 and a second limiting wall 162 located on both sides of the clamping rib 15, and the angle between the first limiting wall 161 and the second limiting wall 162 is α and satisfies: 30°≤α≤90°.

[0062] In some specific embodiments, a first limiting wall 161 and a second limiting wall 162 are formed adjacent to each other on the snap-fitting groove 16, and the first limiting wall 161 and the second limiting wall 162 are respectively located on both sides of the snap-fitting rib 15, and the first wall 111 is inclined relative to the second wall 121, wherein an included angle formed between the first limiting wall 161 and the second limiting wall 162 is α, wherein α is set in the range of 30°≤α≤90°, so that there is a certain adjustment space between the first wall 111 and the second wall 121, and the snap-fitting position of the snap-fitting rib 15 is adjusted, and at the same time, the inclination direction of the first wall 111 is consistent with the inclination direction of the snap-fitting rib 15, and the first wall 111 can fit with the snap-fitting rib 15, thereby improving the assembly effect between the hand buckle plate 2 and the back plate.

[0063] According to some embodiments of the utility model, the second clamping portion is constructed as a clamping protrusion 17 protruding from the second wall 121, and the main body 22 is formed with a clamping groove 18 adapted to the clamping protrusion 17; wherein; a third limiting wall 171 is formed on the clamping protrusion 17, and a fourth limiting wall is formed in the clamping groove 18, the third limiting wall 171 is stopped against the fourth limiting wall and the third limiting wall 171 is inclined away from the second wall 121 in the opening direction of the second groove 12.

[0064] In some specific embodiments, the second clamping portion is configured as a clamping protrusion 17, the clamping protrusion 17 protrudes from the second wall 121 and extends toward the air inlet 101, a clamping groove 18 is formed on the side of the body portion 22 facing the back plate body 1, the clamping protrusion 17 is clamped and matched with the clamping groove 18, so as to limit the movement of the body portion 22 along the thickness direction of the back plate body 1, and a third limiting wall 171 is formed on the side of the clamping protrusion 17 facing the second wall 121, and the third wall is away from the second wall 121 in the opening direction of the second groove 12. The second grooves 12 are arranged at an angle, and a fourth limiting wall is formed in the snap-in groove 18. When the main body 22 is assembled into the second groove 12, the third limiting wall 171 and the fourth limiting wall abut against each other. When the main body 22 moves along the thickness direction of the second groove 12, the two ends of the third limiting wall 171 respectively block the fourth limiting wall to limit the movement of the main body 22 along the thickness direction of the back plate body 1, thereby preventing the main body 22 from escaping from the second groove 12, thereby improving the stability and reliability of the main body 22 in the second groove 12.

[0065] According to some embodiments of the present invention, a transition wall 172 is formed on one side of the clamping protrusion 17 in the opening direction of the second groove 12, and the transition wall 172 is inclined toward the second wall 121 in the opening direction of the second groove 12. Since the thickness of the clamping protrusion 17 gradually increases from the first wall 111 toward the second wall 121, during the assembly process, the interference between the main body 22 and the clamping protrusion 17 gradually increases, and the friction between the clamping groove 18 and the clamping protrusion 17 increases, thereby improving the stability of the main body 22 in the second groove 12. In addition, since the transition wall 172 is formed on the clamping protrusion 17, when the main body 22 is vertically inserted into the second groove 12 from the top of the second groove 12, due to the guiding effect of the transition wall 172 formed on the clamping protrusion 17, even if the interference between the clamping protrusion 17 and the main body 22 gradually increases, the main body 22 can be conveniently and quickly inserted into the second groove 12, thereby improving the assembly efficiency of the hand buckle 2 and the back plate body 1.

[0066] According to some embodiments of the present invention, the transition wall 172 is connected to the third limiting wall 171 and has an arc transition.

[0067] In some specific embodiments, the transition wall 172 is connected to the third limiting wall 171, and the connection between the third limiting wall 171 and the transition wall 172 adopts an arc transition. The arc transition can smoothly connect the third limiting wall 171 and the transition wall 172, reduce the stress concentration of the clamping protrusion 17 during the clamping process of the clamping protrusion 17 and the clamping groove 18, thereby reducing the risk of breakage and damage of the clamping protrusion 17 due to stress concentration. At the same time, the arc transition surface can provide better guiding and positioning effects, making the coordination between the clamping protrusion 17 and the clamping groove 18 simpler and faster.

[0068] According to some embodiments of the utility model, a step portion 13 is formed on the back panel body 1, and the step portion 13 is arranged on at least a portion of the outer periphery of the first groove 11 or at least a portion of the outer periphery of the second groove 12. The step portion 13 is suitable for abutting against at least a portion of the outer periphery of the hand buckle plate 2 to limit the movement of the hand buckle plate 2.

[0069] In some specific embodiments, the back panel body 1 is further formed with a step portion 13 extending along the height direction of the back panel body 1, and the step portion 13 is arranged around at least a portion of the outer circumference of the first groove 11 and at least a portion of the outer circumference of the second groove 12. When the hand clamp 2 is assembled in the second groove 12, the step portion 13 abuts against at least a portion of the edge of the extension portion in the circumferential direction. On the one hand, the step portion 13 supports the main body portion 22, thereby improving the stability of the main body portion 22 in the first groove 11. On the other hand, when the main body portion 22 tends to move along the height direction of the back panel body 1, the step portion 13 blocks the extension portion to limit the movement of the main body portion 22 along the height direction of the back panel, thereby improving the stability and reliability of the hand clamp 2 on the back panel body 1.

Therefore, in the process of the first plug-in board 31 extending into the first groove 24, the interference between the first plug-in board 31 and the protrusion gradually increases, and the friction between the first plug-in board 31 and the protrusion also gradually increases, thereby limiting the movement of the first plug-in board 31, making it impossible for the first plug-in board 31 to easily fall out of the first groove 24, thereby improving the stability and reliability of the connection between the matching part 23 and the filter 3.

[0075] According to some embodiments of the utility model, a second groove 25 is formed on the side of the mating portion 23 facing the back panel body 1, and a limiting protrusion 251 is formed on the bottom wall of the second groove 25; a second plug-in board 32 is formed on the outer peripheral edge of the filter 3, the second plug-in board 32 is accommodated in the second groove 25 and a limiting hole 33 that cooperates with the limiting protrusion 251 is formed on the second plug-in board 32.

[0076] In some specific embodiments, the first plug-in portion is configured as a second groove 25, the second plug-in portion is configured as a second plug-in board 32, the mating portion 23 is formed with a second groove 25 on one side of the back panel body 1 in the thickness direction, the filter screen 3 is further formed with a second plug-in board 32 on the outer peripheral edge of the side close to the first groove 11, the second plug-in board 32 extends in a direction away from the air inlet 101, the second plug-in board 32 and the first plug-in board 31 are both configured as a plurality, the second plug-in board 32 is arranged between two adjacent first plug-in boards 31, the second groove 25 is open toward the air inlet 101 and the inside of the back panel body 1, so that the second plug-in board 32 can be connected along the back panel The body 1 is inserted into the second groove 25 in the thickness and width directions, which reduces the difficulty of assembling the second plug-in board 32 and the second groove 25. A limiting protrusion 251 is formed on the bottom wall of the second groove 25 and protrudes toward the back panel body 1. A limiting hole 33 is formed on the second plug-in board 32 and penetrates the second plug-in board 32 in the thickness direction. When the second plug-in board 32 is inserted into the second groove 25, the limiting protrusion 251 is accommodated in the limiting hole 33 to limit the movement of the second plug-in board 32 in the second groove 25 along the width and height directions of the back panel body 1, thereby further improving the stability and reliability of the connection between the mating part 23 and the filter 3.

[0077] In addition, since the first plug-in board 31, the second plug-in board 32, the first groove 24 and the second groove 25 in the present application have a simple structure, a simple matching method and easy operation, the difficulty of assembling and disassembling the filter 3 and the handle plate 2 is reduced, making the maintenance or replacement of the filter 3 or the handle plate 2 more convenient.

[0078] The air conditioner 100 according to the present invention is briefly described below.

[0079] The air conditioner 100 according to the utility model has a back plate assembly 200 as described in any one of the above embodiments, wherein an air duct is formed inside the back plate assembly 200, and the crossflow impeller 4 is arranged in the air duct; wherein the distance between the center line of the matching portion 23 in the width direction and the back plate rear side wall 14 is L1, and the distance between the center point of the crossflow impeller 4 and the back plate rear side wall 14 is L2, and it satisfies: L1-L2≤3.5. Since the air conditioner 100 according to the utility model is provided with the back plate assembly 200 as described in any one of the above embodiments, the back plate assembly 200 according to the present application increases the air inlet area of ​​the air inlet 101 by reducing the area of ​​the back plate body 1 air inlet 101 occupied by the hand plate 2, thereby increasing the air flow rate in the air duct, reducing the hidden danger of air duct surge, improving the stability and reliability of the air conditioner 100 during operation, and improving the working efficiency of the air conditioner 100.

[0080] In some specific implementations, the traditional hand plate 2 is constructed as a rectangular plate, and a hand groove 21 is formed on the hand plate 2. The size of the hand groove 21 is maintained within a certain range and cannot be changed. The distance from the center line of the traditional hand plate 2 in the width direction to the rear wall of the back plate is less than or equal to the distance from the center point of the cross-flow impeller 4 to the rear side wall 14 of the back plate. In the present application, the center line of the matching portion 23 in the width direction is used to replace the center line of the traditional hand plate 2 in the width direction. When the above conditions are met, the main body 22 of the hand plate 2 can extend in a direction away from the air inlet 101, thereby reducing the area of ​​the air inlet 101 of the back plate body 1 occupied by the hand plate 2, increasing the air inlet area of ​​the air inlet 101, increasing the air flow rate in the air duct, reducing the hidden dangers of duct surge, improving the stability and reliability of the air conditioner 100 during operation, and improving the working efficiency of the air conditioner 100.

[0081] In other specific embodiments, the distance between the center line of the mating portion 23 in the width direction and the rear side wall 14 of the back plate is L1, and the distance between the center point of the crossflow impeller 4 and the rear side wall 14 of the back plate is L2, wherein L1-L2 is in the range of L1-L2≤3.5, that is, when L1-L2 is in the above-mentioned value range, the setting of the hand plate 2 can be realized. In the present application, the area of ​​the air inlet 101 occupied by the hand plate 2 is smaller, and the setting area of ​​the air inlet 101 is larger, which reduces the hidden danger of duct surge and improves the stability and reliability of the air conditioner 100 during operation.
