The sliding groove 3131 has a small width at an end far from the drawing handle 331 to ensure the assembly in place while preventing shaking of the screen assembly 320, and the sliding groove 3131 has a large width at an end near the drawing handle 331 to facilitate the disassembly and assembly of the screen assembly 320.
Fourth embodiment of screen assembly:
as an explanation of the fourth embodiment of the screen assembly according to the present invention, only the differences from the first embodiment of the screen assembly will be explained below.
Referring to fig. 10 to 13, in the embodiment, the fixing member is a metal member, the engaging portion includes an electromagnetic coil, when the electromagnetic coil is powered off, the fixing member is separated from the engaging portion, when the electromagnetic coil is powered on, the fixing member is fixed by the engaging portion, and the fixing member is located at one end of the filter holder 423 away from the pull handle 431.
The air conditioner further comprises a controller, a driving element 40 and a filter screen filth blockage detection component for detecting the filter screen filth blockage situation, the driving element 40 is installed on a panel body 411 of the air conditioner shell 410, a rack portion 424 is arranged on the filter screen support 423, the rack portion 424 extends along the drawing direction, a gear 401 is arranged on a driving shaft of the driving element 40, the gear 401 is matched with the rack portion 424, and the driving element 40 drives the filter screen assembly 42 to move along the drawing direction. Preferably, the drive member 40 is an electric motor. The filter screen filth blockage detection component is an existing component capable of detecting filth blockage of the filter screen, or a component which starts to count down after installation and sends a reminding signal to remind the user of replacing the filter screen through the controller after reaching time.
In this embodiment, the operation method of the air conditioner includes the following steps:
firstly, after the controller acquires that the detection result of the filter screen filth blockage detection component reaches a preset filth blockage value, a signal for reminding a user to replace the filter screen is displayed through a display of the air conditioner so as to remind the user to replace or clean the filter screen.
Then, after the user opens the panel 412 of the air-conditioning case 410 and supports the panel 412 in place, the user issues a command to open the filter screen assembly 42 through a remote controller, a mobile phone, or voice control.
Then, the controller cuts off the current of the electromagnetic coil, and the matching part is separated from the fixed part.
Then, the driving member 40 drives the filter screen assembly 42 to move outward along the drawing direction to a predetermined position.
Finally, the user pulls out the pull handle 431 by applying a force to the filter screen assembly 42 through the pull handle 431, and lightly pushes the filter screen 44 into the chute after cleaning and drying. Then the user sends filter screen assembly 42 and closes the order through remote controller, cell-phone or voice control, and the motor rotates drive gear, and then drives filter screen assembly 42 and moves along slide rail 432, and after filter screen assembly 42 moved extreme position, the solenoid that filter screen assembly 42 kept away from pull handle 431 one side switched on, and the mounting adsorbs fixedly firmly with the cooperation portion to the realization is spacing to filter screen assembly 42, makes filter screen assembly 42 keep in presetting the position, can not remove also motionless rocking.
In this embodiment, because it is that driving piece drive filter screen subassembly removes along the pull direction to realize the automatic pull of filter screen, consequently, can set up the fit clearance between spout and the slide rail enough little, thereby realize the location of filter screen subassembly better, when still avoiding filter screen support and air conditioner casing to mate simultaneously, the user is difficult to the problem of pulling out the filter screen subassembly.
In addition, also can be one for magnet in mounting and the cooperation portion, another is the metalwork, and the mounting can be attracted mutually with cooperation portion and fixed, and the mounting is located the one end that filter screen support kept away from the pull handle.
