Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, and in particular to an evaporator fixing structure, an evaporator and an air conditioning indoor unit. Background Art

[0002] The evaporator of the indoor unit of the air conditioner is mostly made of several evaporators spliced ​​together. The evaporator located on the rear side is mainly matched with the bottom shell, has a smaller width and is installed above the bottom shell water tray. Since the evaporator is a spliced ​​structure, it is easy to deform the small evaporator if it is improperly operated during the bending of the pipes, the turnover of the evaporator, or the installation personnel taking it. After the small evaporator is deformed, a gap will be formed between the evaporator and the area above the bottom shell water tray, and the blown wind will leak from the gap, affecting the cooling and heating effects. Moreover, there are copper tubes under the evaporator. Due to structural limitations, screws cannot be used to fix the lower end of the right side. Therefore, when the air conditioner is subjected to a certain impact force, the right side of the evaporator is prone to collide with the bottom shell and the motor pressure plate, resulting in deformation of the pipes and knocking down of the fins.

[0003] Therefore, the prior art needs to be further developed. Utility Model Content

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] According to an embodiment of the present utility model, an evaporator fixing structure is provided. Figures 1 to 3 , including: a fixing plate 1, the fixing plate 1 is detachably connected to the evaporator 2, and a clearance hole 11 is provided on the fixing plate 1 for the pipeline of the evaporator 2 to pass through; a tongue assembly 3, the tongue assembly 3 is connected to the fixing plate 1, and there is a clearance gap 33 between the tongue assembly 3 and the fixing plate 1, and the tongue assembly 3 extends into the through hole 41 of the motor pressure plate 4 so that the motor pressure plate 4 is clamped in the clearance gap 33, thereby connecting the evaporator 2 to the motor pressure plate 4. Since the right side of the evaporator is all pipelines, the fixing plate 1 needs to be installed between the gaps of the pipelines, so the fixing plate 1 is provided with a clearance hole 11. During installation, the fixing plate 1 is connected to the right side of the evaporator 2, and the pipeline of the evaporator 2 passes through the clearance hole 11. The fixing plate 1 is detachable for timely replacement. The evaporator 2 with the fixing structure is placed on the top of the bottom shell, and the tongue assembly 3 is inserted into the through hole 41 of the motor pressure plate 4 next to it. There is a clearance gap 33 between the tongue assembly 3 and the fixing plate 1, and part of the motor pressure plate 4 is in the clearance gap 33, so that the right side of the evaporator 2 is firmly stuck. Even if vibration occurs and is hit by external force, the evaporator will not become loose or deformed because of the protection of the fixing plate 1, thus avoiding the problem of a large gap between the bottom shell and the motor pressure plate 4 after assembly. The evaporator fixing structure of this embodiment solves the technical problem of the evaporator being not firmly fixed and easily deformed in the related art.

[0026] Specifically, the fixing plate 1 mainly serves to fix the evaporator 2, and has high hardness and strength to ensure that it is not easily deformed after assembly. Since the installation location of the evaporator 2 is in a humid environment, the material of the fixing plate 1 needs to have good corrosion resistance and not be easily rusted after contact with water. Preferably, the fixing plate 1 of this embodiment adopts hot-dip galvanized plate. The tongue assembly 3 is also made of a material with high hardness. The concave-convex structure of the fixing plate 1 and the tongue assembly 3 cooperates with the surrounding parts.

[0027] See also Figure 2In the evaporator fixing structure of this embodiment, the tongue assembly 3 includes: a straight arm section 31, the straight arm section 31 is connected to the fixing plate 1, and the clearance gap 33 is located between the straight arm section 31 and the fixing plate 1; a bent section 32, one end of the bent section 32 is connected to the straight arm section 31, and the other end of the bent section 32 extends toward the fixing plate 1. The straight arm section 31 is used to connect with the motor pressing plate 4, and the bent section 32 is used to hook the motor pressing plate 4 after passing through the motor pressing plate 4.

[0028] See also Figure 2 In the evaporator fixing structure of this embodiment, the length of the connection between the straight arm section 31 and the fixing plate 1 is greater than the length of the connection between the straight arm section 31 and the bent section 32, so that the straight arm section 31 is in an inverted trapezoidal structure. The length and width of the straight arm section 31 are determined according to the size of the slots of the surrounding parts. The straight arm section 31 is designed to be in an inverted trapezoidal structure for easy insertion. The end bent section 32 is designed to be bent at a greater than 90° angle to form a barb, which mainly serves to prevent the motor pressure plate 4 from slipping out after being inserted.

[0029] See also Figure 1 and Figure 2 In the evaporator fixing structure of this embodiment, the evaporator fixing structure further includes a reinforcing plate 5, which is located between the fixing plate 1 and the straight arm section 31. The reinforcing plate 5 is used to increase the structural strength of the tongue assembly 3 to prevent deformation or breakage during installation, which affects the installation efficiency and fixing effect.

[0030] See also Figure 2 In the evaporator fixing structure of this embodiment, a fixing hole 12 is further provided on the fixing plate 1, and the evaporator fixing structure also includes a locking member, which passes through the fixing hole 12 and is connected to the evaporator 2, and the locking member is detachably provided. The fixing hole 12 is provided at the gap of the clearance hole 11, and the fixing hole 12 is a threaded hole. The locking member is a screw, and the screw passes through the threaded hole to fix the fixing plate 1 on the evaporator 2.

[0031] See also Figure 2 In the evaporator fixing structure of this embodiment, the length of the fixing plate 1 is less than or equal to the length of the evaporator 2, and the width of the fixing plate 1 is less than or equal to the width of the evaporator 2. The length of the fixing plate 1 matches the length of the evaporator 2 and does not exceed the length of the evaporator 2 to avoid affecting the fixing. The width of the fixing plate 1 is similar to the width of the right side of the evaporator 2 and does not affect the assembly of the evaporator 2.

[0032] See also Figure 2 In the evaporator fixing structure of this embodiment, there are multiple clearance holes 11, and the multiple clearance holes 11 are arranged at intervals along the length direction of the fixing plate 1. The corresponding clearance holes 11 are arranged according to the number and size of the right side pipelines of the evaporator 2.

[0033] See also Figure 3In the evaporator fixing structure of this embodiment, a convex ring 111 is provided on the clearance hole 11. The convex ring 111 is provided on the side of the fixing plate 1 away from the evaporator 2, and the convex ring 111 surrounds the edge of the clearance hole 11. The edge of the clearance hole 11 is surrounded by the convex ring 111, that is, the clearance hole 11 is set to a flange structure to prevent the pipeline from being cut by the fixing plate 1 made of sharp sheet metal material.

[0034] In the evaporator of this embodiment, the right side of the evaporator is connected to the motor pressure plate 4 via the fixing plate 1 and the tongue assembly 3 to prevent the fins of the evaporator from being hit and deformation.

[0035] In the air-conditioning indoor unit of this embodiment, the evaporator is firmly fixed on the bottom shell and the motor pressure plate 4. Even if it is subjected to a certain impact force, the protection of the fixing plate 1 reduces the probability of deformation, thereby reducing the occurrence of air leakage and ensuring the cooling and heating effects of the air-conditioning indoor unit.
