Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit evaporator technology, and in particular to a two-disassembly sliding rail type easy-to-maintain evaporator filter installation structure. Background Technology

[0002] Currently, existing air conditioner evaporator filters are mainly used in residential, commercial, precision, and portable air conditioners. They usually need to be fixed with clips or bolts, which is cumbersome and can easily scratch users. In addition, the filter is installed inside the panel, and traditional installation is limited by the unit, requiring the filter to be pulled out from above the unit for replacement, which greatly restricts the operating space and increases the difficulty of maintenance.

[0003] To address the shortcomings of existing technologies, it is necessary to design a two-disassembly sliding rail type easy-to-maintain evaporator filter installation structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a two-disassembly sliding rail type easy-to-maintain evaporator filter installation structure.

The design facilitates the installation of other components. The connecting plate is inverted V-shaped, and the opening size is adapted to the tilt angle formed by the two filter support plates 2. One end of the fin 6 is fixed to the heat exchanger bottom plate 1, and the other end is fixed to the heat exchanger top plate. The extension plate of the connecting slide plate 3 and the fin 6 form a bottom sliding groove. The extension plate is set parallel to the fin 6. Several side limiting plates are provided on the lower left plate 42, the upper left plate 41, and the right side plate 5. The side limiting plates and the fin 6 form a side sliding groove. Several air filters 7 are inserted from the disassembly area along the bottom sliding groove and slide into the space between the fin 6 and the side limiting plate through the side sliding groove. The size of the air filter 7 is adapted to the disassembly area after the lower left plate 42 is disassembled. In this embodiment, the air filter 7 is designed as several pieces according to actual requirements. All of them can pass through the disassembly area. In order to reduce the workload, this embodiment designs two air filters 7 on each side for easy and quick disassembly and assembly. This utility model utilizes the bottom sliding groove formed between the extension plate of the connecting slide plate 3 and the fin 6, and the side sliding groove formed between the side limiting plate and the fin to achieve quick installation.
