[0146] In some embodiments of the application, there is a certain gap between the back plate of the indoor unit 100 and the indoor side wall.

[0147] In some embodiments of the application, the indoor unit 100 has an air inlet and outlet mode as follows: Figure 2 The front side and the back side of the indoor unit 100 are air inlets, and the top is an air outlet.

[0148] Specifically, the front side plate of the indoor unit 100 is provided with an indoor front air inlet 112, the back plate of the indoor unit 100 is provided with an indoor back air inlet 113, and the top of the indoor unit 100 is provided with an indoor top air outlet 111.

[0149] The indoor air flows into the inner cavity of the indoor unit 100 from the indoor front air inlet 112 and the indoor back air inlet 113, is heated by the indoor heat exchanger 120, and then flows out from the indoor top air outlet 111.

[0150] The gap between the back plate of the indoor unit 100 and the indoor side wall provides the possibility of air inlet on the back side of the indoor unit 100.

[0151] The air inlet on the front side and the back side of the indoor unit 100 increases the air inlet amount compared with the existing window machine, which helps to improve the heat exchange efficiency of the indoor heat exchanger and the overall heat exchange efficiency of the machine.

[0152] The air inlet on the front side and the back side of the indoor unit 100 cancels the air inlet on the bottom, which solves the problem of increased air resistance of the water pan and overflow and dripping of condensed water caused by the air inlet on the bottom of the indoor unit in the prior art.

[0153] Since there is no need to open an air inlet on the bottom of the indoor unit, there is no need to reserve too much space between the bottom plate of the indoor unit and the water pan, which helps to reduce the overall height of the indoor unit and the indoor space occupied.

[0154] The back plate of the indoor unit is provided with a hollow air inlet, which is matched with a corresponding concave design, which helps to reduce the weight of the indoor unit and improve the structural strength of the back plate of the indoor unit.

[0155] In some embodiments of the present application, removable filter screens are arranged at the indoor front air inlets 112 and the indoor rear air inlets 113, respectively, to filter dust and impurities.

[0156] In some embodiments of the present application, the indoor top air outlet 111 is inclined towards the indoor side, which is beneficial to the flow of the heat-exchanged gas to the indoor side.

[0157] In some embodiments of the present application, a cushion block or an adjustable bolt (not shown) is arranged between the back plate of the indoor unit 100 and the indoor side wall, which improves the installation stability of the indoor unit 100.

[0158] [Indoor unit-indoor heat exchanger]

[0159] In some embodiments of the present application, referring to Figure 15 and Figure 16 , the indoor heat exchanger 120 has a three-section structure, including a heat exchanger first section 121, a heat exchanger second section 122 and a heat exchanger third section 123 connected in sequence.

[0160] The heat exchanger first section 121 extends in the vertical direction, the heat exchanger second section 122 extends obliquely downward from the bottom of the heat exchanger first section 121, and the heat exchanger third section 123 extends obliquely upward from the bottom of the heat exchanger second section 122.

[0161] The heat exchanger first section 121 and the heat exchanger second section 122 are arranged close to the front plate of the indoor unit 100, and the heat exchanger second section 122 extends obliquely downward from the bottom of the heat exchanger first section 121 in a direction away from the front plate.

[0162] The heat exchanger section 123 is located near the rear panel of the indoor unit 100, and extends obliquely upward from the bottom of the heat exchanger section 122 towards the rear panel.

[0163] The front air inlet flows through heat exchanger section 121 and heat exchanger section 122, while the rear air inlet flows through heat exchanger section 123.

[0164] The cross-flow fan 130 is located within the area enclosed by the three-section indoor heat exchanger, making full use of the internal space of the indoor unit 100, resulting in a compact structure.

[0165] After being heated by heat exchangers 121, 122 and 123, the air is collected and flows out from the top air outlet 111.

[0166] The air intakes on the front and rear sides of the indoor unit are perfectly matched with the three-section indoor heat exchanger, allowing each air intake to fully exchange heat with the indoor heat exchanger, greatly improving the heat exchange efficiency of the indoor heat exchanger.

[0167] In some embodiments of this application, the indoor rear air inlet 113 is arranged directly opposite the heat exchanger section 123, so that the gas flowing in from the indoor rear air inlet can directly exchange heat with the heat exchanger section 123, thereby improving the heat exchange efficiency.

[0168] In some embodiments of this application, the angles between the first section 121, the second section 122, and the third section 123 of the heat exchanger and the vertical direction are all less than 40°, ensuring that the indoor heat exchanger 120 drains smoothly after installation, and that the condensate can flow down the fins, preventing the condensate from dripping from the middle of the fins.

[0169] In some embodiments of this application, the top of the three-section heat exchanger 123 is not higher than the connection position between the first-section heat exchanger 121 and the second-section heat exchanger 122. While meeting the heat exchange requirements and the installation requirements of the cross-flow fan, this makes the overall structure of the indoor heat exchanger 120 more compact and helps to reduce the size of the indoor unit 100.

[0170] In some embodiments of this application, the length of the second section 122 of the heat exchanger is greater than the lengths of the first section 121 and the third section 123 of the heat exchanger, respectively. In the limited internal cavity of the indoor unit 100, the effective area of ​​the air intake and the indoor heat exchanger 120 is maximized to improve the heat exchange efficiency.

[0221] [Indoor unit-water pan]

[0222] In some embodiments of the present application, the inner cavity of the indoor unit 100 is provided with a water pan 400 for containing condensed water.

[0223] Referring to Figure 17 , the water pan 400 is provided with a water receiving area 410 and a water containing area 420, the water containing area 420 is provided with an inner water tank 422 and an outer water tank 421 arranged inside and outside, the position where the inner water tank 422 and the outer water tank 421 communicate is provided with a filter portion 500, the water receiving area 410 communicates with the outer water tank 421, and the inner water tank 422 communicates with the water pump 700 through a water drainage pipeline 710.

[0224] The condensed water generated by the indoor heat exchanger 120 first drips into the water receiving area 410, and then flows into the inner water tank 422 through the outer water tank 421 and the filter part 500.

[0225] The outer water tank 421 mainly plays a role of sedimentation of dust particles and dirt in the condensed water.

[0226] Because the water storage area of the outer water tank 421 is large, the water level rises slowly during the condensed water storage process, so that the dust particles and dirt in the condensed water have sufficient time to settle at the bottom of the outer water tank.

[0227] After the condensed water is preliminarily precipitated by the outer water tank 421, the condensed water passes through the filter part 500 for secondary treatment of fine dust particles contained in the condensed water, so as to isolate the fine dust in the outer water tank 421.

[0228] The condensed water after the secondary treatment enters the inner water tank 422, and at this time, the condensed water has reached a high degree of cleanliness, which can effectively avoid the problem of blockage of the drainage pipeline and the drainage pump during the pumping of the drainage pump 700.

[0229] The inner water tank 422 is provided with a float switch (not shown in the figure), and when the water level in the inner water tank 422 reaches a certain height, the float switch is started, and the drainage pump 700 starts pumping.

[0230] The water receiving plate 400 in the embodiment adopts the mode of "outer water tank sedimentation and inner water tank filtration", which effectively improves the dust and dirt removal effect of the condensed water, reduces the blockage gap of the drainage pipeline and the drainage pump, and reduces the maintenance cost of the drainage pump.

[0231] When the machine is used for a period of time, the user can pull out the water block structure on the outer water tank 421, and the water in the outer water tank 421 flows out from the water block position under the high-speed propulsion of gravity-driven flow, carrying the previously deposited silt, dust particles and the like, thereby playing a self-cleaning role.

[0232] In some embodiments of the present application, the total area of the water containing area 420 (the outer water tank 421 + the inner water tank 422) accounts for about 1 / 6 of the total area of the water receiving plate 400, the water containing volume is larger, and more condensed water can be contained.

[0233] The area of the inner water tank 422 is about 1 / 2 of the entire water containing area 420, and more clean condensed water can be contained.

[0234] In some embodiments of the present application, the top of the water containing area 420 is provided with a water tank cover plate (not shown in the figure), so as to avoid the condensed water containing dust particles and dirt falling from the indoor heat exchanger 120 from falling into the water containing area 420.

[0235] In some embodiments of the present application, the above is continued with reference to Figure 17 The inner water tank 422 is arranged at one side of the outer water tank 421, and a water flow channel is formed between the side wall of the inner water tank 422 and the side wall of the outer water tank 421 for the condensed water in the outer water tank to flow through. The filter part 500 is arranged at one end of the water flow channel.

[0236] The water in the outer water tank 421 flows along the water flow channel to the filter part 500, and then flows into the inner water tank 422 after being filtered.

[0237] The water flow channel increases the flow distance and time of the condensed water in the outer water tank 421, which helps to improve the sedimentation of dust particles and dirt.

[0238] In some embodiments of the present application, the above is continued with reference to Figure 18 and Figure 19 The water storage area 420 is arranged at one side of the water tray 400, and one end of the water flow channel extends to the side wall of the water tray 400.

[0239] The side wall of the water tray 400 is provided with a first water outlet 423, and the side wall of the inner water tank 422 is provided with a second water outlet 424. The first water outlet 423 and the second water outlet 424 are opposite to each other, and the first water outlet 423 is provided with a detachable blocking part 430.

[0240] The condensed water in the outer water tank 421 flows into the inner water tank 422 through the second water outlet 424 after being filtered by the filter part 500.

[0241] After the machine runs for a period of time, the user can remove the blocking part 430, and the condensed water in the outer water tank 421 can be discharged through the first water outlet 423 to completely discharge the dust particles and dirt settled in the outer water tank 421.

[0242] After the filter part 500 is removed, the condensed water in the inner water tank 422 can be discharged through the second water outlet 424 and the first water outlet 423.

[0243] That is, after the machine runs for a period of time, the blocking part 430 and the filter part 500 are removed, and the water in the outer water tank 421 and the inner water tank 422 can be completely discharged.

[0244] The first water outlet 423 is arranged at one end of the outer water tank 421, and the second water outlet 424 is arranged at one end of the inner water tank 422. When discharging water, the condensed water in the water tank flows from one end to the other end, which also plays a certain flushing effect on the inner wall of the water tank.

[0245] In some embodiments of the present application, one end of the filter part 500 is arranged in the first water outlet 423 to close the first water outlet 423, and the other end of the filter part 500 is arranged in the second water outlet 424 to connect the outer water tank 421 and the inner water tank 422 through the inner cavity of the filter part 500.
