Description

Technical Field

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

[0002] The evaporator in an air conditioner includes an evaporator main body. An end plate of the evaporator is arranged on the left side or the right side of the evaporator main body. The evaporator main body usually includes several folds, and each fold is provided with fins and copper tubes. It is necessary to fix each fold of the evaporator well through the end plate so that a required included angle is maintained between two adjacent folds.

[0003] At present, a commonly used evaporator end plate includes a left end plate and a right end plate. The right side edge of the left end plate is connected to the left side edge of the right end plate through connecting rib strips. Copper tube holes are arranged in both the left end plate and the right end plate. The included angle between two adjacent folds of the corresponding evaporator body of the left end plate and the right end plate is adjusted by bending the connecting rib strips. When bending the connecting rib strips, the bending stops when the lower half of the right side edge of the left end plate abuts against the lower half of the left side edge of the right end plate. Since there is no positioning and limiting structure between the left end plate and the right end plate, and workers operate according to experience, the left end plate and the right end plate are prone to dislocation (in the front-back direction) during the bending process, resulting in the need for multiple adjustments and affecting the assembly efficiency. Summary of the Utility Model

[0004] The technical problem solved by the utility model is to provide an end plate of an air conditioner evaporator that improves the assembly efficiency of the evaporator.

[0005] The technical solution adopted by the utility model to solve its technical problem is: an end plate of an air conditioner evaporator, including a left end plate and a right end plate. The right side edge of the left end plate is connected to the left side edge of the right end plate through connecting rib strips. Copper tube holes are arranged in both the left end plate and the right end plate. A limiting folding plate is arranged on the front side wall of the left end plate. A left-right direction limiting hole is arranged between the limiting folding plate and the left end plate. A limiting clamping plate is arranged on the left side edge of the right end plate. When bending the connecting rib strips, the limiting clamping plate can be inserted into the left-right direction limiting hole, and the front side wall of the limiting clamping plate abuts against the front side inner wall of the left-right direction limiting hole, and the rear side wall of the limiting clamping plate abuts against the front side wall of the left end plate.

[0006] Furthermore, an installation plate is arranged on the upper side edge of the right end plate, and a connection hole is arranged on the installation plate.

[0007] Furthermore, strengthening convex packages are arranged on the installation plate.

[0008] Furthermore, the left-right direction limiting hole includes a limiting connection hole part and a guiding hole part connected together. The limiting clamping plate includes a limiting connection part and a guiding part. The limiting connection part is connected to the left side edge of the right end plate, and the guiding part is arranged in the middle of the left side edge of the limiting connection part;

[0009] When bending the bent connecting rib, the guiding part passes through the guiding hole part and the limiting connecting part is arranged in the limiting connecting hole part in a matching manner.

[0010] Furthermore, a wire routing slot is arranged on the lower side edge of the right end plate.

[0011] Furthermore, a flanging structure is arranged at the wire routing slot.

[0012] Furthermore, a connecting pin is arranged on the left side edge of the left end plate.

[0013] Furthermore, a reinforcing rib is arranged beside the connecting pin.

[0014] The beneficial effects of the present utility model are as follows: A limiting folding plate is arranged on the front side wall of the left end plate, and a left-right direction limiting hole is arranged between the limiting folding plate and the left end plate. A limiting clamping plate is arranged on the left side edge of the right end plate. When bending the bent connecting rib, the limiting clamping plate can be clamped into the left-right direction limiting hole, and the front side wall of the limiting clamping plate abuts against the front inner wall of the left-right direction limiting hole, and the rear side wall of the limiting clamping plate abuts against the front side wall of the left end plate. When assembling the evaporator, first install the evaporator end plate on the evaporator body, and then adjust the angle between two adjacent folds of the evaporator body corresponding to the left end plate and the right end plate by bending the bent connecting rib. During the process of bending the bent connecting rib, the limiting clamping plate is gradually clamped into the left-right direction limiting hole. At the same time, the front side wall of the limiting clamping plate abuts against the front inner wall of the left-right direction limiting hole, and the rear side wall of the limiting clamping plate abuts against the front side wall of the left end plate. Stop bending when the lower half of the right side edge of the left end plate abuts against the lower half of the left side edge of the right end plate. During the bending process of the left end plate and the right end plate, the limiting clamping plate, the left-right direction limiting hole, and the front side wall of the left end plate play a role in positioning and limiting, effectively reducing the possibility of front-back direction misalignment during the bending process of the left end plate and the right end plate. The operation is simple and convenient, without multiple adjustments, significantly improving the assembly efficiency of the evaporator; moreover, the limiting clamping plate can be arranged in the left-right direction limiting hole, ensuring the connection strength between the two, ensuring the stability of the angle between two adjacent folds of the evaporator body, and improving the strength of the entire evaporator end plate.

Specific embodiments

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The directions involved in the following text are based on Figure 1 the orientations of the components in

[0022] As Figure 1 , Figure 2 shown, the air conditioner evaporator end plate of the present invention includes a left end plate 1 and a right end plate 2. The right side edge of the left end plate 1 is connected to the left side edge of the right end plate 2 through a connecting rib 3. Copper tube holes 12 are provided in both the left end plate 1 and the right end plate 2. A limiting folding plate 4 is provided on the front side wall of the left end plate 1. A left-right direction limiting hole 6 is provided between the limiting folding plate 4 and the left end plate 1. A limiting clamping plate 5 is provided on the left side edge of the right end plate 2. When the connecting rib 3 is bent, the limiting clamping plate 5 can be inserted into the left-right direction limiting hole 6, and the front side wall of the limiting clamping plate 5 is in contact with the front inner wall of the left-right direction limiting hole 6, and the rear side wall of the limiting clamping plate 5 is in contact with the front side wall of the left end plate 1, as Figure 3 , Figure 4 shown.

[0023] The front side wall of the limiting clamping plate 5 being in contact with the front inner wall of the left-right direction limiting hole 6 and the rear side wall of the limiting clamping plate 5 being in contact with the front side wall of the left end plate 1 means that the limiting clamping plate 5 and the left-right direction limiting hole 6 as well as the limiting clamping plate 5 and the left end plate 1 can move relative to each other in the left-right direction, but cannot move relative to each other in the front-rear direction.

[0024] During the assembly of the evaporator, first, the evaporator end plate is installed on the evaporator body 13, and then the included angle between two adjacent folds of the evaporator body 13 corresponding to the left end plate 1 and the right end plate 2 is adjusted by bending the connecting rib 3. During the process of bending the connecting rib 3, the limiting clamping plate 5 is gradually inserted into the left-right direction limiting hole 6. At the same time, the front side wall of the limiting clamping plate 5 is in contact with the front inner wall of the left-right direction limiting hole 6, and the rear side wall of the limiting clamping plate 5 is in contact with the front side wall of the left end plate 1. When the lower half of the right side edge of the left end plate 1 abuts against the lower half of the left side edge of the right end plate 2, stop bending. During the bending process of the left end plate 1 and the right end plate 2, the limiting clamping plate 5, the left-right direction limiting hole 6, and the front side wall of the left end plate 1 play a role in positioning and limiting, effectively reducing the possibility of the front-rear direction misalignment of the left end plate 1 and the right end plate 2 during the bending process. The operation is simple and convenient, without the need for multiple adjustments, and significantly improves the assembly efficiency of the evaporator.

[0025] Specifically, when bending the bending connecting rib 3, in order to facilitate the clamping of the limit clamping plate 5 into the left-right direction limit hole 6 and improve the positioning and limiting effect. For another example Figure 1 , Figure 2 As shown in the figure, the left-right direction limit hole 6 includes a limit connection hole part 61 and a guide hole part 62 connected together. The limit clamping plate 5 includes a limit connection part 51 and a guide part 52. The limit connection part 51 is connected to the left side of the right end plate 2, and the guide part 52 is arranged in the middle of the left side of the limit connection part 51. When bending the bending connecting rib 3, the guide part 52 passes through the guide hole part 62 and the limit connection part 51 is arranged in the limit connection hole part 61 in a matching manner. The size of the guide part 52 is much smaller than the size of the limit connection hole part 61, and the guide part 52 is also easier to pass through the guide hole part 62 to guide the limit connection part 51 to be arranged in the limit connection hole part 61.

[0026] In order to improve the strength of the limit connection part 51 arranged in the limit connection hole part 61, both the limit connection part 51 and the limit connection hole part 61 are rectangular.

[0027] In order to enable the air conditioner evaporator end plate to be fixedly installed on the evaporator body 13. For another example Figure 1 As shown in the figure, an installation plate 7 is arranged on the upper side of the right end plate 2, and a connection hole is arranged on the installation plate 7. The connection screw passes through the connection hole to detachably arrange the right end plate 2 on the evaporator body 13. In order to improve the strength of the installation plate 7, the installation plate 7 is provided with a reinforcing convex hull 8.

[0028] In order to facilitate the arrangement of the electric heating wire. For another example Figure 1 As shown in the figure, a wire routing slot 9 is arranged on the lower side of the right end plate 2, and the electric heating wire is clamped in the wire routing slot 9. A flanging structure is arranged at the wire routing slot 9. The flanging structure prevents the wire routing slot 9 from cutting off the electric heating wire, and the flanging structure can also reinforce the strength of the wire routing slot 9.

[0029] During the assembly of the evaporator, it is necessary to connect the motor cover to the air conditioner evaporator end plate. In order to realize the connection between the motor cover and the air conditioner evaporator end plate. For another example Figure 1 As shown in the figure, a connection pin 10 is arranged on the left side of the left end plate 1, and the connection pin 10 is inserted into the motor cover pin hole to form a fastening structure. In order to improve the strength of the connection pin 10, a reinforcing rib 11 is arranged beside the connection pin 10.
