Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an end cover assembly and an air conditioner. Background Art

[0002] With the rapid development of variable frequency air conditioning technology, the requirements for various components of air conditioners are becoming higher and higher. Energy consumption, noise, and cooling efficiency have become the main parameters affecting air conditioner performance and have attracted much attention from consumers. At the same time, as competition in the air conditioning industry becomes increasingly fierce, users have also placed higher demands on product structure, appearance, and after-sales service.

[0003] As we all know, air conditioners are used to circulate and adjust the temperature of the air entering the indoor unit. After long-term use, they need to be disassembled to clean and maintain the internal structure of the air conditioner. However, the existing split wall-mounted air conditioners have a complex assembly structure between the end cover and the middle frame, which is inconvenient to disassemble and assemble. When the end cover of the air conditioner needs to be opened for observation or maintenance of some parts, the end cover needs to be completely removed from the middle frame first, and then installed accordingly after the maintenance is completed. The operation is cumbersome and inconvenient for online maintenance of the air conditioner. At the same time, there is also the disadvantage of damaging normal parts during the disassembly process.

[0004] It can be seen from this that it is very necessary to simplify the difficulty of disassembling and assembling the end cover inside the air conditioner, avoid completely removing the end cover assembly, and reduce the difficulty of operation. Summary of the invention

[0005] The problem solved by the present invention is to connect the cover plate with the middle frame in a hinged manner, so that the cover plate can be rotatably held on the middle frame, thereby solving the problems that the end cover needs to be completely removed and the operation is troublesome.

[0006] In order to solve the above problems, the present invention provides an end cover assembly for an air conditioner indoor unit, the air conditioner indoor unit also includes a middle frame, the end cover assembly includes a cover plate and a connector, one end of the connector is connected to the middle frame, the other end of the connector is provided with a rotating part, the rotating part is rotatably connected to the cover plate to expose the internal components of the middle frame. This arrangement allows the cover plate to be partially separated from the middle frame after opening, and the cover plate can be rotated by the connector to remove the internal parts from the left and right ends of the air conditioner without causing interference, which is convenient for disassembly and maintenance of the air conditioner.

[0007] Furthermore, the connector is arranged at the peripheral edge of the side end surface of the middle frame. This arrangement can completely expose the internal components of the middle frame after rotating the cover plate, and this arrangement can avoid interference from the connector, making it easier to perform online maintenance on the air conditioner from the side end surface of the middle frame.

[0008] Furthermore, the cover plate is rotated 90-180° in the vertical direction by the connecting piece. This arrangement can flip the cover plate by at least 90°, making it easy to extract components such as the axial flow blades of the air conditioner from the side end surface for cleaning and maintenance.

[0009] Furthermore, the rotating part is a rotating shaft, and a rotating shaft base for accommodating the rotating shaft and allowing the rotating shaft to rotate is provided on the cover plate at a position corresponding to the rotating shaft, and the rotating shaft base is vertically arranged on the plane where the cover plate is located. This arrangement further defines that the rotating part is a rotating shaft, has a simple structure, and is easy to machine.

[0010] Furthermore, the connector also includes a telescopic portion, which includes a sleeve and a telescopic rod, the telescopic rod can slide out or retract along the inside of the sleeve, and the sleeve is detachably connected to the middle frame. This arrangement can realize the cover plate being pulled out from the middle frame for a certain distance before being rotated, and the cover plate pulling distance can be set as needed, which has a wide range of applications.

[0011] Furthermore, the telescopic part also includes a stop limit assembly for limiting the sliding travel of the telescopic rod. This arrangement can ensure that the cover plate does not detach from the middle frame.

[0012] Furthermore, the stop limit assembly includes more than one groove, and the telescopic rod is correspondingly provided with a convex portion that matches the groove or the round hole. The stop limit assembly can be set to multiple gears and stop at a corresponding position according to the needs of maintenance personnel; at the same time, the stop limit assembly is set as a groove, which has a simple structure and is easy to machine.

[0013] Furthermore, the cover plate includes a body and a reinforcement strip, wherein the reinforcement strip is arranged at the edge of the body and is perpendicular to the plane where the body is located. This arrangement can improve the mechanical strength of the cover plate and increase its service life; at the same time, by arranging the reinforcement strip, the appearance of the cover plate is more beautiful.

[0014] Furthermore, the cover plate is provided with a positioning post, and the middle frame is provided with a positioning hole at a position corresponding to the positioning post; during assembly, the positioning post is inserted into the positioning hole to complete the positioning between the cover plate and the middle frame. This arrangement can ensure rapid positioning between the cover plate and the middle frame, and improve the assembly efficiency between the two.

[0015] Furthermore, the cover plate is also provided with a connection assembly, and there are multiple connection assemblies, which are arranged at equal intervals along the circumference of the body. The arrangement can set the number of buckles according to needs, taking into account the tightness and convenience of assembly; at the same time, the structure is simple and easy to machine.
