The hand pull bolt 110 is connected to one end of the first movable plate 100 by screws. When the fan coil 106 and the fin 109 need to be regularly cleaned and disinfected, The staff slides the coil 106 and the fin 109 out of the chassis 118 through the hand pull bolt 110, the slide rod 102 and the slide rail 103. The staff uses high-temperature steam to easily clean and disinfect the dirt and dust on the coil 106 and the fin 109. It can be more clearly seen whether the dirt clumps on the coil 106 and the fin 109 have been cleaned or cleaned, and the staff does not need to remove the coil 106 and the fin 109 from the chassis 118.

The staff uses high-temperature steam to clean and disinfect.
[0040] By setting the transparent cover 300, the dirt generated by cleaning the coil 106 and the fin 109 can be effectively prevented from falling to the ground or splashing onto the staff. The dirt can be conveniently collected for treatment, reducing the pollution of the working environment by the dirt and increasing the disinfection time of the high-temperature steam mist on the coil 106 and the fin 109.
[0041] When in use, first, when the central air-conditioning fan coil 106 is cleaned and disinfected, the staff slides the coil 106 and the fin 109 out of the chassis 118 through the hand pull bolt 110, the slide rod 102 and the slide rail 103, and then uses the transparent cover 300 to cover the coil 106 and the fin 109. The staff uses high-temperature steam to clean and disinfect. After cleaning and disinfection, the transparent cover 300 is removed from one end of the chassis 118, and then the coil 106 and the fin 109 are pushed into the chassis 118, and the slide rod 102 is fixed using the fixing block 104, and the motor 203 is started.
[0042] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model.
