[0158] The indoor air flows into the inner cavity of the indoor unit 100 from the indoor front air inlet 112 and the indoor rear air inlet 113, is heat-exchanged by the indoor heat exchanger 120, and then flows out from the indoor top air outlet 111.

[0159] The gap between the back plate of the indoor unit 100 and the indoor side wall provides the possibility of air inlet at the back side of the indoor unit 100.

[0160] The front side and the back side of the indoor unit 100 inhale air at the same time, which significantly increases the air inlet amount compared with the existing window unit, and helps to improve the heat exchange efficiency of the indoor heat exchanger, thereby improving the overall heat exchange efficiency of the machine.

[0161] The front side and the back side are simultaneously air-in, which cancels the bottom air-in, solves the problem of the water tray increasing the air resistance and the condensate water overflowing and dripping caused by the bottom air-in of the indoor unit in the prior art.

[0162] Since the air-in port is not needed in the bottom of the indoor unit, and a large space is not needed between the bottom plate of the indoor unit and the water tray, the overall height of the indoor unit is reduced, and the indoor space is reduced.

[0163] The rear back plate of the indoor unit is provided with a hollow air-in port, 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 rear back plate of the indoor unit.

[0164] In some embodiments of the present application, the indoor front air-in port 112 and the indoor rear air-in port 113 are respectively provided with detachable filter screens to filter dust and impurities.

[0165] In some embodiments of the present application, the indoor top air-out port 111 is inclined towards the indoor side, which is beneficial to the flow of the heat-exchanged gas to the indoor side.

[0166] In some embodiments of the present application, a cushion block or an adjustable bolt (not shown) is arranged between the rear back plate of the indoor unit 100 and the indoor side wall, which improves the installation stability of the indoor unit 100.

[0167] [Indoor unit - indoor heat exchanger]

[0168] In some embodiments of the present application, referring to Figure 15 and Figure 16 , the indoor heat exchanger 120 is 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.

[0169] 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.

[0170] The heat exchanger first section 121 and the heat exchanger second section 122 are arranged close to the front side 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 away from the front side plate.

[0171] The heat exchanger third section 123 is arranged close to the rear back plate of the indoor unit 100, and the heat exchanger third section 123 extends obliquely upward from the bottom of the heat exchanger second section 122 close to the rear back plate.

[0172] The front side air-in flows through the heat exchanger first section 121 and the heat exchanger second section 122, and the back side air-in flows through the heat exchanger third section 123.

[0173] 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.

[0174] After being heated by heat exchangers 121, 122 and 123, the air is collected and flows out from the top air outlet 111.

[0175] 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.

[0176] 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.

[0177] 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.

[0178] 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.

[0179] 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.

[0194] The cochlea tongue strip 921 includes a cochlea tongue strip one part 9211 and a cochlea tongue strip two part 9212 in an integral structure, both in a V-shaped structure, the included angle between the two is an acute angle, the cochlea tongue strip one part 9211 is connected with the base plate 92211, and the cochlea tongue strip two part 9212 is connected with the first flap 92212, so as to install the cochlea tongue strip 921 to the cochlea tongue strip support 922.

[0195] During assembly, the cochlea tongue strip 921 is first installed to the cochlea tongue strip support 922, and then the cochlea tongue strip support 922 is installed to the main skeleton 910, so as to complete the assembly of the air duct skeleton 900.

[0196] In some embodiments of the present application, the cochlea tongue strip two part 9212 is provided with a first abutting plate 92121 and a second abutting plate 92122 on the side facing the cochlea tongue strip support 922, the first abutting plate 92121 extends along the length direction of the cochlea tongue strip two part 9212, the second abutting plate 92122 extends along the height direction of the cochlea tongue strip two part 9212, and a plurality of second abutting plates 92122 are spaced apart along the length direction of the cochlea tongue strip two part 9212.

[0199] Through the assembly between the cochlea tongue strip one part 9211 and the cochlea tongue strip support 922 and the assembly between the first flap 92212 and the limiting groove 92123, the displacement of the cochlea tongue strip 921 in the up-down direction and the left-right direction can be limited, and through the abutting between the second abutting plate 92122 and the first flap 92212, the assembly stability of the cochlea tongue strip 921 is further improved, and the noise caused by the shaking of the cochlea tongue strip 921 during air outlet is avoided.

[0200] In some embodiments of the present application, the second flap 92213 and the third flap 92214 are arranged on the substrate 92211, and extend downward and away from the main framework 910, respectively. The third flap 92214 is located outside the second flap 92213, and the second flap 92213 is located outside the first flap 92212. The bottom end of the third flap 92214 is lower than the bottom end of the second flap 92213.

[0201] The top of the indoor heat exchanger 120 (specifically, the top of the first heat exchanger section 121) is close to the second flap 92213 and located inside the third flap 92214, so as to avoid a gap between the top of the indoor heat exchanger 120 and the volute tongue assembly 920, and thus the front side air inlet of the indoor unit can pass through the indoor heat exchanger 120 for heat exchange.

[0202] In some embodiments of the present application, the substrate 92211 is provided with a plurality of clamping convex structures 92215 along the length direction thereof.

[0214] The slide structure is located on the side close to the opening 334, and the limiting structure 915 is located on the side away from the opening 334, when the filter screen 930 is inserted through the opening 334, it first passes through the guiding action of the slide structure, and the insertion movement is relatively smooth and reliable, and when the end of the filter screen 930 abuts against the limiting structure 915, it is inserted into place.

[0215] In some embodiments of the present application, the slide structure includes an upper slide 9141 and a lower slide 9142, the upper part of the filter screen 930 is provided in the upper slide 9141, and the lower part is provided in the lower slide 9142, and the upper and lower sides both slide, improving the sliding reliability.

[0216] In some embodiments of the present application, referring to Figures 36 to 38One end of the filter screen 930 is provided with a stop plate 931, the stop plate 931 is provided with a first plug-in part 932 and a first clamping part 933, and the stop plate 931 abuts against the side of the shell of the indoor unit 100 to limit the insertion displacement of the filter screen 930.

[0217] The side of the shell of the indoor unit 100 is provided with a second plug-in part 335 and a second clamping part 336 near the opening 334.

[0222] [Indoor unit-water pan]

[0223] In some embodiments of the present application, the indoor unit 100 is provided with a water pan 400 in the inner cavity for containing condensed water.

[0224] 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 are communicated is provided with a filter part 500, the water receiving area 410 is communicated with the outer water tank 421, and the inner water tank 422 is communicated with the water pump 700 through a water drainage pipeline 710.

[0225] The condensed water generated by the indoor heat exchanger 120 first 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 part 500 in sequence.

[0226] The outer water tank 421 mainly plays a role of sedimentation of dust particles and dirt with relatively large mass in the condensed water.

[0227] 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 the dust particles and dirt in the condensed water have sufficient time to settle to the bottom of the outer water tank.

[0228] The condensed water is preliminarily settled in the outer water tank 421 and then is treated by the filtering part 500 to remove the fine dust particles in the condensed water, so that the fine dust particles are isolated in the outer water tank 421.

[0229] The condensed water after the secondary treatment enters the inner water tank 422, and the condensed water has reached a high degree of cleanliness at this time, which can effectively avoid the problem of clogging of the drainage pipeline and the drainage pump when the drainage pump 700 is pumping.

[0230] The inner water tank 422 is provided with a float switch (not shown), 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.

[0231] The water pan 400 in the embodiment adopts the mode of "outer water tank settlement and inner water tank filtration", which effectively improves the dust and dirt removal effect of the condensed water, reduces the clogging gap of the drainage pipeline and the drainage pump, and reduces the maintenance cost of the drainage pump.

[0232] When the machine is used for a period of time, the user can remove 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.

[0233] 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 pan 400, and the water containing volume is larger, which can contain more condensed water.

[0234] The area of the inner water tank 422 is about 1 / 2 of the entire water containing area 420, which can contain more clean condensed water.

[0235] 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) to prevent the condensed water containing dust particles and dirt falling from the indoor heat exchanger 120 from falling into the water containing area 420.

[0236] In some embodiments of the present application, continuing to refer to Figure 17 , the inner water tank 422 is arranged at the 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, and the filtering part 500 is arranged at one end of the water flow channel.

[0237] The water in the outer water tank 421 flows along the water flow channel to the filtering part 500, and then flows into the inner water tank 422 after being filtered.

[0238] 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.

[0239] In some embodiments of the present application, in combination with Figure 18 Figure 19 The water collection area 420 is arranged at one side of the edge corner of the water pan 400, and one end of the water flow channel extends to the side wall of the water pan 400.

[0240] The first water outlet 423 is arranged on the side wall of the water pan 400, and the second water outlet 424 is arranged on the side wall of the inner water tank 422. The first water outlet 423 is opposite to the second water outlet 424, and the first water outlet 423 is provided with a detachable blocking part 430.

[0241] The condensed water in the outer water tank 421 is filtered by the filter part 500 and then flows into the inner water tank 422 through the second water outlet 424.

[0242] 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, so that the dust particles and dirt in the outer water tank 421 can be completely discharged.

[0243] The filter part 500 is removed, and the condensed water in the inner water tank 422 can be discharged through the second water outlet 424 and the first water outlet 423.

[0244] 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.

[0245] 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.

[0246] 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.

[0247] In the process of flowing from the outer water tank 421 to the inner water tank 422 through the inner cavity of the filter part 500, the condensed water in the outer water tank 421 automatically completes the secondary filtration of dust particles.

[0248] The filter part 500 can be taken out from the outside of the water pan 400, which is convenient for cleaning and replacing the filter part 500.

[0249] In some embodiments of the present application, the side wall of the water pan 400 is provided with a mounting column 440, the mounting column 400 is provided with a through hole communicating with the outer water tank 421, and one end (i.e. the outer extension part 518) of the filter part 500 extends into the through hole through the first water outlet 423.​

[0250] The outer side of the mounting column 440 is detachably provided with a plugging part 430 to plug the through hole. Specifically, the outer periphery of the mounting column 440 is provided with external threads, and the plugging part 430 is in the form of a plug cover structure, and the inner periphery of the plugging part 430 is provided with internal threads. The plugging part 430 is screwed onto the mounting column 440.

[0251] When the filter part 500 needs to be disassembled, the plugging part 430 is first removed, and at this time, the outer extension part 518 is pulled by hand, so that the filter part 500 can be pulled out.

[0252] In some embodiments of the present application, the side wall of the outer water tank 421 includes a first outer side wall 4211, a second outer side wall 4212, a third outer side wall 4213, and a fourth outer side wall 4214 connected in sequence.

[0253] The side wall in the inner water tank 422 for forming the water flow channel includes 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 connected in sequence. Each adjacent two side walls are in the form of an L-shaped structure.

[0254] The first inner side wall 4221 is connected with the fourth outer side wall 4211, the fourth inner side wall 4224 is connected with the third outer side wall 4213, and the third inner side wall 4223 and the third outer side wall 4213 have a gap for accommodating the filter part 500.

[0255] The first water inlet 423 is arranged on the third outer side wall 4213, and the second water inlet 424 is arranged on the third inner side wall 4223.

[0256] The structure of the water containing area 420 designed in this way makes the water flow channel formed between the outer water tank 421 and the inner water tank 421 in the form of an L-shaped structure. The long and narrow water flow channel is more conducive to the sedimentation of dust particles and dirt.

[0257] The filter part 500 is arranged at the corner position where the outer water tank 421 and the inner water tank 422 communicate. The water flow at this corner position will have a buffering effect, which is conducive to improving the secondary filtering effect of dust particles.

[0258] In some embodiments of the present application, a plurality of water guide ribs are arranged in the water receiving area 410 to guide the flow of condensed water.

[0259] In some embodiments of the present application, a plurality of water distribution ribs are arranged at the position where the side edge of the outer water tank 421 communicates with the water receiving area 410. The water flow gap for the water flow into the outer water tank 421 is formed between adjacent two water distribution ribs, which plays a role in uniform flow of condensed water.

[0260] Since the indoor unit in the present case cancels the bottom side air inlet, the bottom plate 160 of the indoor unit is in a closed structure. In some embodiments of the present application, with reference to Figures 42 to 44The water pan 400 is connected with the bottom plate 160, and a closed space is formed between the water pan 400 and the bottom plate 160. The air in the closed space has a low heat conduction coefficient, which can reduce the heat transfer between the water pan 400 and the bottom plate 160. The temperature of the water pan 400 does not affect the temperature of the bottom plate 160, and the condensation of the bottom plate 160 is effectively prevented.

[0261] In some embodiments of the present application, the water pan 400 and the bottom plate 160 can also be filled with thermal insulation materials to further reduce the heat transfer between the water pan 400 and the bottom plate 160.
