Referring to fig. 7, the panel 210 is provided with a mounting hole 212 for mounting a switch body 410, and an inner side surface of a bottom end of the mounting hole 212 is provided with an inwardly protruding clamping portion 213. The side wall of the switch body 410 is provided with a protruding limit buckling part 412, and the top surface of the limit buckling part 412 is an inclined surface, that is, the limit buckling part 412 is of an inverted buckling structure. A flange 413 is provided on a side wall of the switch body 410 below the limit locking part 412, and a locking groove is formed between the flange 413 and the limit locking part 412. The upper portion of the switch body 410 is pushed into the mounting hole 212 on the upper side of the clamping portion 213 by the limiting clamping portion 412 in an inclined surface and interference fit mode, and meanwhile the clamping portion 213 in the mounting hole 212 is clamped into the clamping groove on the switch body 410 to be fixed. The up-down and left-right matching gaps of the clamping groove and the clamping part 213 of the push-spring switch 400 are designed to be about 0.2-0.3mm, so that the firmness of the push-spring switch 400 after assembly is ensured.

In the present embodiment, as shown in fig. 5, the four sides of the panel 210 are respectively disposed with a long-strip-shaped notch 214, and the cover 220 is disposed in the notch 214. The outer side portion of the cover 220 is hinged to the panel 210, and the inner side portion of the cover 220 is provided with a reverse latch 420, i.e., the cover 220 is turned open from the inner side. The notch groove 214 is disposed at the outermost side of the panel 210, which not only facilitates the installation of the cover plate 220, but also does not occupy the area of the air outlet 211 of the panel 210. In this embodiment, the cross-sectional dimension of the panel assembly 200 is larger than the dimension of the upper outer casing 100, a certain distance is provided between the return air filter 300 and the outer side edge of the panel 210, and the width of the cover plate 220 is slightly larger than the distance, so that the return air filter 300 can be supported on the cover plate 220.

Referring to fig. 6, the cover plate 220 includes a base plate 221, end plates 222 connected to both ends of the base plate 221, and an outer plate 223 connected to outer sides of the base plate 221. The height of the outer panel 223 is consistent with the thickness of the side of the panel 210, so that the cover 220 and the panel 210 are integrated in appearance. A rotating shaft 2221 is disposed on the outer side surface of the end plate 222, a rotating shaft mounting hole 215 is disposed on the side wall opposite to the notch groove 214, and the rotating shaft 2221 is mounted in the rotating shaft mounting hole 215.

The bottom plate 221 is provided with a limiting rib 224, and the return air filter screen 300 is supported on the limiting rib 224. In the present embodiment, two limiting ribs 224 are symmetrically disposed, and the height of the two limiting ribs 224 is consistent with the height of the outer side plate 223 of the cover plate 220.

Because the cover plate 220 is opened, the return air filter screen 300 falls under the action of gravity, and in order to prevent the return air filter screen 300 from suddenly falling and injuring an operator after the cover plate 220 is opened, as shown in fig. 3 and 4, a limiting boss 312 is arranged on the side of the return air filter screen 300 sliding along the outer casing 100. The stopping portion 112 is disposed on the sliding channel 111 of the side pillar 110, and the stopping portion 112 is disposed on the lower side of the limiting boss 312 and is used for cooperating with the limiting boss 312 to stop the downward movement of the return air filter screen 300. After the cover plate 220 is opened, the return air filter screen 300 falls to a certain height and is blocked by the limiting boss 312, so that the return air filter screen 300 can be prevented from completely falling off from the outer shell 100, and an operator can further pull the return air filter screen 300 downwards to completely separate the return air filter screen 300 from the outer shell 100. The height of the limiting boss 312 is guaranteed to be not more than 2mm, so that the return air filter screen 300 can be assembled through a small interference when the return air filter screen 300 is assembled.

In the present embodiment, as shown in fig. 2, the return air filter 300 includes a frame 310 and a filter 320 fixed to the frame 310, and a grip groove 311 is formed at a lower end of the frame 310. The operator can pull the return air screen 300 downward or push it upward through the grip slots 311.

The height difference between the limiting boss 312 and the stopping portion 112 is greater than the height difference between the bottom end of the frame 310 and the top of the grip groove 311. That is, after the cover plate 220 is opened, the descending height of the return air filter screen 300 is greater than the height difference between the bottom end of the frame 310 and the top of the grip groove 311, so that the grip groove 311 can extend downward from the panel 210, thereby facilitating the disassembly operation.

The utility model discloses among the indoor set of ceiling type air conditioner, the dismantlement and the installation operating procedure of return air filter screen 300 specifically as follows:

when the return air filter screen 300 of the air conditioner needs to be cleaned, the cover plate 220 outside the panel 210 is firstly found, and the position a marked with the mark a is pressed, as shown in fig. 10, at this time, the matching state of the reversing pin 420 of the cover plate 220 and the push switch 400 is switched from the clamping state of the clamping jaw 411 to the unlocking state of the clamping jaw 411, the cover plate 220 is opened by 90 degrees under the action of gravity along the rotating shafts 2221 at the two ends of the cover plate, the return air filter screen 300 slowly slides down along the slide rail 111 of the side column 110 under the action of gravity, when the limiting boss 312 of the return air grille is just clamped at the stopping part 112 of the slide rail 111, the return air grille stops falling, and the position of the grasping hand groove 311 of the return air grille just leaks out. At this time, the grip of the return air filter screen 300 is held by hand and pulled down, so that the return air filter screen 300 can be slightly pulled out for cleaning, replacement and other operations, as shown in fig. 12.

After the return air filter screen 300 is cleaned or replaced by a new one, the return air filter screen 300 firstly slides into the slide rail 111 of the side post 110, then the limit boss 312 of the return air filter screen 300 is clamped on the stop portion 112 of the slide rail 111 with a slight force, at this time, the cover plate 220 is closed, the limit rib 224 on the cover plate 220 pushes the return air filter screen 300 to continuously ascend along the slide rail 111, when the reverse latch 420 on the cover plate 220 is clamped on the claw 411 of the push-spring switch 400, the cover plate is pressed upwards with a slight force, so that the reverse latch 420 of the cover plate 220 is matched with the claw 411 of the push-spring switch 400, the state unlocked by the claw 411 is converted into the claw 411 clamping state, and the return air filter screen 300 is kept fixed at the position under the support of the limit rib 224 of the.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
