When this embodiment dismouting filter screen, need not to unpack top cap 16 apart, direct 16 both sides pull from the top cap can take out, and it is convenient to wash.

An air inlet grille 10111 is arranged at the indoor air inlet 1011, wherein the air inlet grille 10111 is parallel to the length direction of the top cover 16, namely, parallel to the axis of the cross flow fan 22, so as to facilitate air inlet.

The air inlet grille 10111 and the plane of the top cover 16 are arranged at a certain angle, so that integrated vision can be formed on the front side of the air conditioner, internal components are prevented from being exposed, and the attractiveness is improved.

When the first filter screen 181 is installed, the guide ribs 1812 of the first filter screen 181 are inserted into the slide channels 161 of the top cover 16, and after the first filter screen 181 is pushed by the handle 1814 until the first filter screen is installed in place, the first filter screen is clamped on the left shell 14 by the first buckle 1813. When the first filter screen 181 is detached, the first buckle 1813 of the first filter screen 181 is separated from the left casing 14, and the handle 1814 is pulled to pull the first filter screen 181 out of the slide channel 161 of the top cover 16.

In order to collect the condensed water of the indoor unit assembly, the indoor unit assembly of this embodiment has a water receiving device.

As shown in fig. 9 and 10, the water receiving device is formed on the framework 23 and the volute tongue 24. Wherein, the framework 23 is positioned below the second bottom end of the indoor heat exchanger 21, and the volute tongue 24 is positioned below the first bottom end of the indoor heat exchanger 21. The volute tongue 24 is provided with a first water receiving portion 246 located at the first bottom end of the indoor heat exchanger 21, the first water receiving portion 246 is used for receiving condensed water at the first bottom end of the indoor heat exchanger 21, a water leakage hole 2461 is formed in the end portion of the first water receiving portion 246, and the condensed water of the first water receiving portion 246 leaks out through the water leakage hole 2461 to prevent the first water receiving portion 246 from overflowing with the condensed water. The framework 23 is provided with a second water receiving portion 234 located at the second bottom end of the indoor heat exchanger 21, and the second water receiving portion 234 is used for receiving the condensed water at the second bottom end of the indoor heat exchanger 21. The end of the frame 23 has a water guide portion 235 communicating with the second water receiving portion 234, and the water guide portion 235 is used for receiving the water leakage from the water leakage hole 2461 and guiding the water leakage from the water leakage hole 2461 to the second water receiving portion 234.

Preferably, the water guide portion 235 is partially located below the water leakage hole 2461, and directly receives the condensed water dropping from the water leakage hole 2461.

In order to ensure smooth drainage of the first water receiving portion 246, the first water receiving portion 246 gradually decreases from a position far from the water leakage hole 2461 to a position close to the water leakage hole 2461. The condensed water received by the first water receiving portion 246 can smoothly flow into the water leakage holes 2461 and be discharged from the water leakage holes 2461 to the water guide portion 235.

In order to improve the drainage efficiency of the second water receiving portion, a second water leakage hole 2341 is provided in the middle of the second water receiving portion 234. Because the second water leakage hole 2341 is disposed in the middle of the second water receiving portion 234, the condensed water at the two ends of the second water receiving portion 234 can flow to the second water leakage hole 2341 quickly and be discharged, and overflow of the condensed water of the second water receiving portion 234 is avoided.

Further, in order to accelerate the drainage of the second water receiving portion 234, the second water receiving portion 234 is gradually lowered from the direction away from the second water leakage hole 2341 to the direction close to the second water leakage hole 2341, so as to ensure the smooth flow of water.

In order to improve the water transfer efficiency of water transfer part 235, water transfer part 235 gradually decreases from a position away from second water receiving part 234 to a position closer to second water receiving part 234.

The water guide part 235 is a groove located at the end of the framework 23, and since the framework 23 is also used for carrying the fan 22, in order to prevent the water in the water guide part 235 from affecting the fan 22, the framework 23 includes a boss 236 for carrying the fan 22, the water guide part 235 is located at the periphery of the boss 236, and the water guide part 235 is lower than the boss 236.

When the condensed water is collected, the condensed water at the first bottom end of the indoor heat exchanger 21 is collected by the first water receiving portion 246, the condensed water at the second bottom end is collected by the second water receiving portion 234, the condensed water collected by the first water receiving portion 246 is discharged to the water guiding portion 235 through the water leakage hole 2461, the water guiding portion 235 guides the condensed water of the first water receiving portion 246 to the second water receiving portion 234, and the condensed water of the second water receiving portion 234 is discharged from the second water leakage hole 2341.

As shown in fig. 14 to 17, the outdoor unit assembly 3 will be described as follows:

the outdoor unit assembly 3 includes a second chamber 102, and an outdoor air inlet 1021 and an outdoor air outlet 1023 are formed on a housing corresponding to the second chamber 102. An outdoor heat exchanger 31 and a centrifugal fan 33 are provided in the second chamber 102. The centrifugal fan 33 comprises an air suction opening 331, the outdoor heat exchanger 31 is communicated with the air suction opening 331, an air outlet 333 of the centrifugal fan 33 is communicated with an outdoor air outlet 1023, and the outdoor heat exchanger 31 is used for exchanging heat with air sucked by an outdoor air inlet 1021. That is, when the centrifugal fan 33 operates, outdoor air is sucked in through the outdoor air inlet 1021, exchanges heat with the outdoor heat exchanger 31, enters the centrifugal fan 33 through the air suction inlet 331, and is discharged to the outside through the air outlet 333 and the outdoor air outlet 1023 of the centrifugal fan 33. The centrifugal fan can improve the air supply distance and prevent air return. The outdoor air inlet 1021 is located between the outdoor heat exchanger 31 and the left casing 14 on the rear casing 13, and the outdoor air outlet 1023 is located between the outdoor heat exchanger 31 and the second partition 1025 on the rear casing 13.

The outdoor air inlet and the outdoor air outlet of the embodiment are both arranged on the rear shell of the shell. Of course, the outdoor air outlet may be disposed on the rear casing of the casing, and the outdoor air inlet may be disposed on the left casing or the right casing of the casing, both being within the protection scope of the present invention.
