Indoor machine-water pan)

Referring to fig. 17, a water receiving area 410 and a water containing area 420 are disposed in the water receiving tray 400, an inner water tank 422 and an outer water tank 421 are disposed inside and outside the water containing area 420, a filter screen structure 500 is disposed at a position where the inner water tank 422 is communicated with the outer water tank 421, the water receiving area 410 is communicated with the outer water tank 421, and the inner water tank 422 is communicated with a drain pump 700 through a drain line 710.

The condensed water generated by the indoor heat exchanger 120 firstly drops into the water receiving area 410, and then flows into the inner water tank 422 through the outer water tank 421 and the filter screen structure 500 in sequence.

The outer water tank 421 mainly plays a role in settling the dust particles and dirt with large mass in the condensed water.

Because the water storage area of the outer water tank 421 is large, the rising speed of the water level is slow in the process of storing the condensed water, so that the dust particles and dirt in the condensed water have enough time to automatically settle to the bottom of the outer water tank.

The condensed water passes through the filter screen structure 500 after being preliminarily precipitated in the outer water tank 421, and fine dust particles contained in the condensed water are secondarily treated, so that the fine dust is isolated in the outer water tank 421.

The condensed water after the secondary treatment enters the inner water tank 422, and the condensed water reaches a higher cleaning degree, so that the problem that impurities block a drainage pipeline and a drainage pump when the drainage pump 700 extracts the water can be effectively avoided.

A float switch (not shown) is provided in the inner water tank 422, and when the water level in the inner water tank 422 reaches a certain level, the float switch is activated, and the drain pump 700 starts pumping water.

Water collector 400 in this embodiment adopts the mode of "outer basin subsides, and interior basin filters", effectively promotes the dust filth removal effect of comdenstion water, reduces row's drainage pipe way and drain pump and blocks up the gap, reduces drain pump maintenance cost.

After the machine is used for a period of time, a user can pull out the water blocking structure on the outer water tank 421, and the water in the outer water tank 421 is entrained with the sediment, dust particles and the like deposited previously under the high-speed propelling action of the gravity-driven flow and flows out from the water blocking position, so that the self-cleaning effect is achieved.

In some embodiments of the present application, the total area of the water containing region 420 (the outer water tank 421+ the inner water tank 422) occupies about 1/6 of the total area of the water-receiving tray 400, and the water containing volume is larger, so that more condensed water can be contained.

The area of inner water channel 422 is approximately 1/2 of the entire water containing area 420, and can contain more clean condensate.

In some embodiments, a cover plate (not shown) is disposed on the top of the water containing region 420 to prevent condensed water containing dust particles and dirt dropping from the indoor heat exchanger 120 from falling into the water containing region 420.

In some embodiments of the present application, with reference to fig. 17, the inner water tank 422 is disposed on one side of the outer water tank 421, a water flow channel for flowing condensed water in the outer water tank is formed between a side wall of the inner water tank 422 and a side wall of the outer water tank 421, and the filter screen structure 500 is disposed at one end of the water flow channel.

The water in the outer water tank 421 flows along the water flow channel to the filter screen structure 500, and then flows into the inner water tank 422 after being filtered.

The water flow channel increases the flowing distance and time of the condensed water in the outer water tank 421, which is helpful to improve the settling effect of the dust particles and the dirt.

In some embodiments of the present application, referring to fig. 18 and 19, the water containing region 420 is disposed on a side of the water-receiving tray 400 near the corner, and one end of the water flow channel extends to a side wall of the water-receiving tray 400.

The condensed water in the outer water tank 421 is filtered by the filter screen structure 500 and then flows into the inner water tank 422 through the second mounting hole 424.

After the machine is operated for a period of time, a user can take down the blocking part 430 by himself, and condensed water in the outer water tank 421 can be discharged through the first mounting opening 423, so that dust particles and dirt settled in the outer water tank 421 can be completely discharged.

When the screen structure 500 is taken out, the condensed water in the inner water tank 422 may be discharged through the second mounting hole 424 and the first mounting hole 423.

That is, after the machine is operated for a certain period of time, the blocking portion 430 and the screen structure 500 are removed, and the water in the outer water tank 421 and the inner water tank 422 can be completely drained.

The first mounting port 423 is provided at one end of the outer water tank 421, and the second mounting port 424 is provided at one end of the inner water tank 422, so that condensed water in the water tank flows from one end to the other end during water discharge, and a certain washing effect is exerted on the inner wall of the water tank.

The filter screen structure 500 can be taken out from the outside of the water pan 400, which is convenient for cleaning and replacing the filter screen structure 500.

In some embodiments of the present disclosure, a mounting post 440 is disposed outside a sidewall of the water pan 400, a through hole communicating with the outer water tank 421 is disposed in the mounting post 400, and one end (i.e., the extending portion 518) of the filter screen structure 500 extends into the through hole through the first mounting opening 423.

The outer side of the mounting post 440 is detachably provided with a blocking portion 430 for blocking the through hole. Specifically, the periphery of the mounting column 440 is provided with external threads, the blocking portion 430 is of a blocking cover structure, the inner periphery of the blocking portion is provided with internal threads, and the blocking portion 430 is screwed on the mounting column 440.

When the filter structure 500 needs to be disassembled, the plugging portion 430 is removed, and the protruding portion 518 is pulled by hand, so that the filter structure 500 can be pulled out.

In some embodiments, the outer tub 421 includes a first outer sidewall 4211, a second outer sidewall 4212, a third outer sidewall 4213 and a fourth outer sidewall 4214 connected in sequence.

The side walls of the inner water tank 422 for forming the water flow channel include a first inner side wall 4221, a second inner side wall 4222, a third inner side wall 4223 and a fourth inner side wall 4224 which are connected in sequence, and every two adjacent side walls are in an L-shaped structure.

The first mounting opening 423 is formed in the third outer sidewall 4213, and the second mounting opening 424 is formed in the third inner sidewall 4223.

The water containing area 420 structure designed in this way makes the water flow channel formed between the outer water tank 421 and the inner water tank 421 be L-shaped, and the long and narrow water flow channel is more beneficial to the sedimentation of dust particles and dirt.

The filter screen structure 500 is arranged at the corner position where the outer water tank 421 is communicated with the inner water tank 422, and water flow can obtain a buffering effect at the corner position, so that the secondary filtering effect of dust particles is improved.

In some embodiments of the present application, a plurality of water guiding ribs are disposed in the water receiving area 410 to guide the condensed water.
