[0107] The embodiment discloses a saddle type air conditioner, referring to Figure 1 which comprises an indoor unit 100 located at the indoor side, an outdoor unit 200 located at the outdoor side, and a saddle bridge structure 300 connecting the indoor unit 100 and the outdoor unit 200.

[0108] The saddle type air conditioner is of N type structure, and the indoor unit 100 and the outdoor unit 200 are respectively arranged at two ends of the saddle bridge structure 300 and located at the same side of the saddle bridge structure 300.

[0109] When the saddle type air conditioner is installed on the window, the saddle bridge structure 300 is directly seated on the window, the indoor unit 100 is located at the indoor side, and the outdoor unit 200 is located at the outdoor side.

[0110] Since the indoor unit 100 and the outdoor unit 200 are both located below the window, the saddle type air conditioner solves the problem of blocking sunlight after the installation of the existing integrated window air conditioner.

[0111] The separation of the indoor unit 100 and the outdoor unit 200 by the saddle bridge structure 300 helps to avoid the transmission of noise of the outdoor unit 200 to the indoor side, improving the user's comfort.

[0112] The indoor unit 100 mainly includes a casing, an indoor heat exchanger 120, a water pan 400, a cross-flow fan 130, an air duct and the like.

[0113] The outdoor unit 200 mainly includes a casing, an outdoor heat exchanger 230, an axial flow fan 250, a compressor 220 and the like.

[0114] [Indoor side air inlet and outlet]

[0115] In some embodiments of the present application, there is a certain gap between the back plate of the indoor unit 100 and the indoor side wall.

[0116] In some embodiments of the present application, the indoor unit 100 has the air inlet and outlet mode as follows: referring to Figure 2 , the front side and the back side of the indoor unit 100 have air inlets, and the top has an air outlet.

[0117] Specifically, the front 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.

[0118] 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 heat-exchanged by the indoor heat exchanger 120, and then flows out from the indoor top air outlet 111.

[0119] 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.

[0120] The simultaneous air inlets at the front side and the back side of the indoor unit 100 significantly increase the air inlet amount compared with the existing window air conditioner, which helps to improve the heat exchange efficiency of the indoor heat exchanger, thereby improving the overall heat exchange efficiency of the machine.

[0121] The simultaneous air inlets at the front side and the back side cancel the air inlet at the bottom, thereby solving the problem of the increase of the wind resistance of the water pan and the overflow and dripping of the condensed water caused by the air inlet at the bottom of the indoor unit in the prior art.

[0122] Since there is no need to open an air inlet at 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 occupation.

[0123] The rear backboard of the indoor unit is provided with a hollow air inlet, which is matched with a corresponding concave design, so as to reduce the weight of the indoor unit and improve the structural strength of the rear backboard of the indoor unit.

[0124] In some embodiments of the present application, detachable filter screens (not shown) are arranged at the indoor front air inlets 112 and the indoor rear air inlets 113, respectively, to filter dust and impurities.

[0125] 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.

[0126] In some embodiments of the present application, a cushion block or an adjustable bolt (not shown) is arranged between the rear backboard of the indoor unit 100 and the indoor side wall, so as to improve the mounting stability of the indoor unit 100.

[0127] [Outdoor side air inlet and outlet]

[0128] In some embodiments of the present application, the rear backboard of the outdoor unit 200 has a certain gap with the outdoor side wall.

[0129] In some embodiments of the present application, the outdoor unit 200 adopts the air inlet and outlet mode as follows: air is inhaled from the left and right sides, the top and the back of the outdoor unit 200, and air is exhausted from the front side of the outdoor unit 200. Figure 1

[0130] Specifically, the rear backboard of the outdoor unit 200 is provided with an outdoor rear air inlet 213, the left and right side plates of the outdoor unit 200 are respectively provided with outdoor side air inlets 212, the top plate of the outdoor unit 200 is provided with an outdoor top air inlet 214, and the front side plate of the outdoor unit 200 is provided with an outdoor front air outlet 211.

[0131] Outdoor air flows into the inner cavity of the outdoor unit 200 from the outdoor rear air inlet 213, the outdoor side air inlets 212 and the outdoor top air inlet 214, is heat-exchanged by the outdoor heat exchanger 230, and then flows out from the outdoor front air outlet 211.

[0132] In some embodiments of the present application, the bottom of the outdoor unit 200 is provided with a bottom air inlet (not shown).

[0133] The gap between the rear backboard of the outdoor unit 200 and the outdoor side wall provides a possibility for air to be inhaled from the back side of the outdoor unit 200.

[0134] The outdoor unit 200 adopts the air inlet mode of four sides, which increases the air inlet amount, is beneficial to improve the heat dissipation efficiency of the outdoor heat exchanger, and improves the heat exchange efficiency of the whole machine.

[0135] ​The back plate and the bottom plate of the outdoor unit 200 are provided with hollow air inlets, which are matched with corresponding concave designs, so as to reduce the weight of the outdoor unit and improve the structural strength of the back plate and the bottom plate of the outdoor unit.

[0136] The outdoor rear air inlet 213 is opposite to the axial flow fan 250 in the outdoor unit, so as to greatly enhance the air suction capacity of the outdoor axial flow fan 250 during operation and improve the heat dissipation effect of the outdoor heat exchanger by air flow.

[0137] The outdoor bottom air inlet can increase the air inlet amount while avoiding the problem of suction of impurities such as fallen leaves.

[0138] In some embodiments of the present application, a cushion block (not shown) or an adjustable bolt 260 is arranged between the back plate of the outdoor unit 200 and the outdoor side wall, so as to improve the installation stability of the outdoor unit 200.

[0139] [Saddle bridge structure]

[0140] In some embodiments of the present application, the saddle bridge structure 300 can be telescopic, and the distance between the indoor unit and the outdoor unit is adjusted by adjusting the length of the saddle bridge structure 300, so as to adapt to walls with different thicknesses.

[0142] The saddle bridge structure 300 can be provided with multiple telescopic gears, so as to be convenient for adjustment and use.

[0143] In some embodiments of the present application, referring to Figure 3 and Figure 4 , the saddle bridge structure 300 includes an indoor saddle bridge shell 310 and an outdoor saddle bridge shell 320.

[0144] The structure of the indoor saddle bridge shell 310 refers to Figures 5 to 7 , a first through cavity 313 is formed in the indoor saddle bridge shell 310, and the indoor saddle bridge shell 310 is fixedly connected with the indoor unit 100.

[0145] The structure of the outdoor saddle bridge shell 320 refers to Figures 8 to 10 , a second through cavity 323 is formed in the outdoor saddle bridge shell 320, and the outdoor saddle bridge shell 320 is fixedly connected with the outdoor unit 200.

[0146] The indoor saddle bridge shell 310 and the outdoor saddle bridge shell 320 are mutually sleeved, and the indoor saddle bridge shell 310 and the outdoor saddle bridge shell 320 can move relative to each other, so as to realize the telescopic function of the saddle bridge structure 300.

[0147] In some embodiments, the outdoor saddle bridge shell 320 is sleeved on the outer side of the indoor saddle bridge shell 310, likeFigure 4 As shown.

[0148] In some other embodiments, the indoor saddle bridge shell 310 is sleeved outside the outdoor saddle bridge shell 320.

[0149] In some embodiments of the present application, a sliding part is arranged between the indoor saddle bridge shell 310 and the outdoor saddle bridge shell 320, so that the sliding movement between the indoor saddle bridge shell 310 and the outdoor saddle bridge shell 320 is more reliable and smooth.

[0150] The sliding part can be a sliding rail structure, or a slide and block structure arranged between the two.

[0151] In some embodiments of the present application, the saddle bridge structure 300 is provided with an indoor vertical part extending downward on the side facing the indoor unit 100, the indoor vertical part constitutes the back plate of the indoor unit 100 and is fixedly connected with the bottom plate of the indoor unit 100, and the indoor vertical part is provided with an indoor rear air inlet 113.

[0152] The saddle bridge structure 300 is provided with an outdoor vertical part extending downward on the side facing the outdoor unit 200, the outdoor vertical part constitutes the back plate of the outdoor unit 200 and is fixedly connected with the bottom plate of the outdoor unit 200, and the outdoor vertical part is provided with an outdoor rear air inlet 213.

[0153] The saddle bridge structure 300 is fixedly connected with the indoor unit 100 and the outdoor unit 200 through two vertical parts, which helps to improve the structural stability between the indoor unit 100, the outdoor unit 200 and the saddle bridge structure 300.

[0154] The saddle bridge structure 300 can bear part of the weight of the indoor unit 100 and the outdoor unit 200, and transfer the weight to the window through the saddle bridge structure 300, which helps to improve the safety of the whole machine after installation of the saddle type air conditioner and reduce the risk of falling.

[0155] [Water soaking pipe arrangement]

[0156] In some embodiments of the present application, referring to Figure 26 , the rear partition plate 240 is used to mount components such as the outdoor heat exchanger and the fan, and the top of the rear partition plate 240 is provided with a water storage tank 241, and the condensed water generated on the indoor unit side is introduced into the water storage tank 241 and the bottom plate of the outdoor unit. Part of the water soaking pipe 930 in the heat exchange pipeline is located in the water storage tank 241, and the other part is located on the bottom plate of the outdoor unit.

[0157] The condensed water is used to cool the upper and lower parts of the water soaking pipe at the same time, which improves the cooling effect of the water soaking pipe.

[0158] The arrangement of the water storage tank 241 fully utilizes the rear partition plate structure, which is compact and does not cause additional increase in the volume of the outdoor unit.

[0159] In some embodiments of the present application, one end of the water storage tank 241 is provided with a water outlet 2414, and the condensed water in the water storage tank 241 falls to the bottom plate of the outdoor unit through the water outlet 2414. The condensed water drawn out from the indoor side first cools the top water bubble pipe, and then the condensed water is poured down to the bottom plate to continue to cool the lower water bubble pipe, thereby improving the cooling effect and the heat exchange efficiency of the whole machine.

[0160] The process of the condensed water dripping down from the water storage tank 241 is actually a cooling process, which reduces the temperature of the condensed water, thereby improving the cooling effect of the lower water bubble pipe.

[0161] In some embodiments of the present application, the water storage tank 241 includes a first water storage tank section 2411 and a second water storage tank section 2412 in communication, the width of the first water storage tank section 2411 is greater than the width of the second water storage tank section 2412, the length of the first water storage tank section 2411 is less than the length of the second water storage tank section 2412, the width refers to the direction extending along the front and back sides of the outdoor unit, and the length refers to the direction extending along the left and right sides of the outdoor unit.

[0162] The water inlet of the water storage tank 241 is in communication with the first water storage tank section 2411, the water outlet 2414 is arranged at the end of the second water storage tank section 2412, and the water bubble pipe in the water storage tank 241 extends circumferentially along the inner wall of the water storage tank 241.

[0163] The condensed water drawn out by the drain pipe flows into the first water storage tank section 2411 first, the volume of the first water storage tank section 2411 is relatively large, which plays a role of buffering water, the condensed water flows from the first water storage tank section 2411 to the second water storage tank section 2412, the slender structure of the second water storage tank section 2412 plays a role of accelerating water flow, thereby improving the cooling effect of the water bubble pipe, and the condensed water finally flows out from the water outlet 2414 at the other end and drips onto the bottom plate of the outdoor unit. The condensed water is cooled again during the dripping process to improve the cooling effect of the water bubble pipe in the bottom plate.

[0164] Since the first water storage tank section 2411 and the second water storage tank section 2412 are not the same in width, a stepped transition is generated between them, which plays a limiting role for the water bubble pipe 930 and improves the stability of the water bubble pipe in the water storage tank 241.

[0165] In some embodiments of the present application, the water storage tank 241 is arranged at the top rear side of the rear partition plate 240, the first water storage tank section 2411 and the second water storage tank section 2412 are transitionally connected by a bevel structure 2413 at the sidewall away from the rear side of the rear partition plate 240, the bevel structure 2413 plays a role of guiding and pre-accelerating water flow, thereby improving the smoothness of the condensed water flowing from the first water storage tank section 2411 to the second water storage tank section 2412.

[0166] [Electrical box installation]

[0167] In some embodiments of the present application, referring to Figure 11 The interior of the saddle bridge structure 300 is a through cavity, and the electric appliance box 600 is arranged in the interior through cavity of the saddle bridge structure 300.

[0168] The electric appliance box 600 is arranged at a position fully utilizing the interior space of the saddle bridge structure 300, so that the overall structure is more compact.

[0169] In some embodiments of the present application, a gap is formed between the electric appliance box 600 and the side wall of the saddle bridge structure 300 for the heat exchange pipe (referring to the return air pipe group and the supercooling pipe group) and the drainage pipe to pass through.

[0170] The electric appliance box 600 is arranged against one side of the through cavity, and a gap for the heat exchange pipe and the drainage pipe of the air conditioner to pass through is formed between the electric appliance box 600 and the other side of the through cavity. The heat exchange pipe and the drainage pipe extend from one side of the electric appliance box 600, so that the interior structure of the saddle bridge structure 300 is more regular and compact.

[0171] The saddle bridge structure 300 in the embodiment not only serves to connect the indoor unit 100 and the outdoor unit 200, but also serves to mount the electric appliance box 600, pass through the pipes and wires, so that the structure is more compact and multifunctional.

[0172] In some embodiments of the present application, one side of the electric appliance box 600 is provided with an inclined wall 610, which is inclined in the vertical plane, so as to avoid interference with the heat exchange pipe and the drainage pipe when the saddle bridge structure 300 is stretched or contracted.

[0173] In some embodiments of the present application, taking the example that the outdoor saddle bridge shell 320 is sleeved outside the indoor saddle bridge shell 310, the electric appliance box 600 is fixedly arranged on the horizontal portion 3111 of the indoor saddle bridge L-shaped bottom plate, the top of the electric appliance box 600 is open, the internal electric appliances are conveniently mounted, and the indoor saddle bridge cover plate 312 is used to seal the open top of the electric appliance box 600.

[0174] In some embodiments of the present application, the electric appliance box 600 is provided with a buffer sealing portion 315 at a position in contact with the inner wall of the through cavity of the saddle bridge structure 300. The buffer sealing portion 315 serves to reduce vibration and prevent condensate water condensed on the inner wall of the saddle bridge structure 300 from falling into the electric appliance box 600, so as to improve the waterproof performance of the electric appliance box 600.

[0175] As a specific embodiment, referring to Figure 7 The inner side of the indoor saddle bridge cover plate 312 is provided with the buffer sealing portion 315, the buffer sealing portion 315 is in abutting sealing contact with the top of the electric appliance box 600, and the buffer sealing portion 315 covers the open top of the electric appliance box 600.

[0176] The top open structure of the electric appliance box 600 facilitates the installation of the electric appliance inside the electric appliance box 600, and the inner wall of the saddle bridge structure 300 (specifically, the indoor saddle bridge cover plate 312) serves as a top cover of the electric appliance box 600, thereby simplifying the structure and reducing the cost.

[0177] [Structure of heat exchange pipeline]

[0178] In some embodiments of the present application, with reference to Figure 27 , the heat exchange pipeline 900 of the saddle type air conditioner mainly includes a return gas pipe group 910, a supercooling pipe group 920, an exhaust pipe 940, and a bubble water pipe 930.

[0179] One end of the supercooling pipe group 920 is connected to the liquid inlet end of the evaporator (corresponding to the indoor heat exchanger), and the other end is connected to the bubble water pipe 930; one end of the return gas pipe group 910 is connected to the gas outlet end of the evaporator, and the other end is connected to the suction port of the compressor 220; one end of the exhaust pipe 940 is connected to the gas inlet end of the condenser (corresponding to the outdoor heat exchanger), and the other end is connected to the exhaust port of the compressor 220; one end of the bubble water pipe 930 is connected to the supercooling pipe group 920, and the other end is connected to the liquid outlet end of the condenser.

[0180] With reference to Figure 11 and Figure 13 , the return gas pipe group 910 includes a first return gas pipeline section 911, a second return gas pipeline section 912, and a third return gas pipeline section 913 which are sequentially connected, the first return gas pipeline section 911 is connected to the indoor heat exchanger 120, the third return gas pipeline section 913 is connected to the compressor 220, and the second return gas pipeline section 912 is in a U-shaped structure and located in the inner cavity of the saddle bridge structure 300.

[0181] The three-section structure of the return gas pipe group 910 facilitates processing and improves the process level.

[0182] The return gas pipe group 910 uses copper pipes to avoid refrigerant leakage.

[0183] When the saddle bridge structure 300 is stretched, the U-shaped second return gas pipeline section 912 plays a certain buffering role for the pipeline stretching, thereby meeting the stretching function of the saddle bridge structure 300.

[0184] In some embodiments of the present application, the U-shaped structure of the second return gas pipeline section 912 is a semicircular structure. During the operation of the whole machine, the vibration of the pipeline is actually the transmission of force, and when the semicircular structure of the second return gas pipeline section 912 is under stress, the force on the arc structure will cancel each other out in the transmission, thereby playing a damping role. At the same time, the arc-shaped form of the pipeline is designed, which is relatively square or similar to the square form of the pipeline. Under the same space, the amount of pipeline used by the semicircular structure form is relatively small, thereby reducing the cost of the pipeline to a certain extent.

[0185] In some embodiments of the present application, the second return gas pipeline section 912 is arranged in the gap between the electric appliance box 600 and the inner cavity side wall of the saddle bridge structure 300, and horizontally surrounds one side of the electric appliance box 600, fully utilizes the internal space of the saddle bridge structure 300, and realizes the pipe running.

[0186] The electric appliance box 600 is located in the space surrounded by the U-shaped structure of the second return gas pipeline section 912, and when the saddle bridge structure 300 is stretched, the left and right sides of the electric appliance box 600 can have sufficient excess to ensure that the pipeline does not contact the electric appliance box 600 during the pulling process.

[0187] In some embodiments of the present application, a spring 914 is sleeved on the second return gas pipeline section 912 to prevent the second return gas pipeline section 912 from being crushed or collapsed during the stretching process.

[0188] The outer periphery of the second return gas pipeline section 912 is covered with a heat insulation sleeve (not shown), which covers the outer periphery of the spring 914 to prevent condensed water from flowing into the electric appliance box 600.

[0189] The two ends of the second return gas pipeline section 912 are respectively flared, which is used for connecting the first return gas pipeline section 911 and the third return gas pipeline section 913, and also plays a limiting role on the spring.

[0190] In some embodiments of the present application, the third return gas pipeline section 913 includes a third return gas pipeline first section 9131, a third return gas pipeline U-shaped section 9132 and a third return gas pipeline second section 9133 connected in sequence, the opening of the third return gas pipeline U-shaped section 9132 faces upward, the third return gas pipeline first section 9131 is connected with the second return gas pipeline section 912, and the third return gas pipeline second section 9133 is connected with the suction port of the compressor 220.

[0191] The third return gas pipeline U-shaped section 9132 plays an auxiliary stretching deformation role, can bear a small part of the stretching force, plays a buffering role, avoids giving the compressor a transverse force after being directly connected with the compressor 220, and causes the compressor to be affected in performance and vibration.

[0192] In some embodiments of the present application, the plane where the third return gas pipeline U-shaped section 9132 is located is parallel to the central axis of the compressor 220, which further plays a role in reducing vibration.

[0193] The first return gas pipeline section 911 and the third return gas pipeline section 913 are fixed on the back plate of the indoor unit and the outdoor unit by a binding wire or the like, so that the return gas pipeline does not generate a stretching force on other pipelines when being stretched, and deformation or breakage of the pipeline is avoided.

[0194] In some embodiments of the present application, refer to Figure 14The supercooling pipe group 920 passes through the saddle bridge structure, and a U-shaped section 921 is arranged on the supercooling pipe group 920. The U-shaped section 921 is located in the saddle bridge structure 300, and the U-shaped section 921 is consistent with the U-shaped structure of the second gas return pipe section 912, so as to ensure the consistency of the whole machine.

[0195] The heat shrink tube is arranged on the supercooling pipe group 920, so as to avoid the condensed water from flowing into the electric appliance box 600 and to avoid direct contact with other pipelines.

[0196] In some embodiments of the present application, with reference to Figure 14 The supercooling pipe group 920 further includes a supercooling pipe first section 922, a supercooling pipe second section 923 and a supercooling pipe third section 924 connected in sequence. The supercooling pipe first section 922 extends horizontally along the upper position of the back plate of the outdoor unit to be connected with the U-shaped section 921 of the supercooling pipe group. The supercooling pipe second section 923 extends vertically along the side of the back plate of the outdoor unit to the bottom plate of the outdoor unit. The supercooling pipe third section 924 extends horizontally along the bottom plate of the outdoor unit.

[0197] The supercooling pipe group 920 and the gas return pipe group 910 do not interfere with each other, and the structure is compact.

[0198] In some embodiments of the present application, with reference to Figure 11 The compressor 220 is installed at a corner of the outdoor unit 200. Correspondingly, the third gas return pipe section 913 and the compressor 220 are located on the same side of the inner cavity of the outdoor unit 200. The third drain pipe section 830 is located on the other side of the inner cavity of the outdoor unit, that is, the third gas return pipe section 913 and the third drain pipe section 830 are arranged oppositely in the outdoor unit and do not interfere with each other.

[0199] The second drain pipe section 820 and the second gas return pipe section 912 are bundled together at one or two places by binding wires, but cannot be tightly bound to prevent the drain pipe from being flattened, and only serve as a limiting function.

[0200] [Evacuation of heat exchange pipeline]

[0201] Corresponding to the stretching structure of the saddle bridge structure, the lengths of the gas return pipe group 910 and the supercooling pipe group 920 are increased compared with conventional window units. In some embodiments of the present application, the gas return pipe group 910 and the supercooling pipe group 920 are provided with evacuation pipes. Two evacuation points are used to simultaneously evacuate the heat exchange pipeline, so as to improve the evacuation efficiency and production efficiency.

[0202] In some embodiments of the present application, the first evacuation pipe 951 is arranged on the third gas return pipe section 913, specifically on the third gas return pipe section 9132. The two are welded, which is convenient for processing.

[0203] In some embodiments of the present application, the supercooling pipe group 920 is provided with a second evacuation pipe 952 at a position close to the outdoor heat exchanger, specifically, the second evacuation pipe 952 is arranged on the third supercooling pipe 924, facilitating production and processing.

[0204] In some embodiments of the present application, the first evacuation pipe 951 can also be arranged on the exhaust pipe 940.

[0208] The indoor condensate water is introduced into the water storage tank 241 through the drain pipe 800, and the water outlet pipe of the drain pump 700 is connected to the water inlet of the first water storage tank section 2411.

The second U-shaped bending section 822 is horizontally located in the inner cavity of the saddle bridge structure 300 and on the side of the electrical box 600.

[0215] The second U-shaped bending section 822 plays an auxiliary stretching deformation role to ensure that when the saddle bridge structure 300 is stretched to the maximum length, the drainage pipe 800 can still guarantee sufficient length to meet the normal drainage requirement.

[0216] In some embodiments of the present application, the first drainage pipe section 810 includes a first drainage pipe vertical section 811 and a first drainage pipe horizontal section 812 connected in sequence.

[0252] The front and rear air inlets of the indoor unit are perfectly matched with the three-section indoor heat exchanger, and each air inlet can fully exchange heat with the indoor heat exchanger, thereby greatly improving the heat exchange efficiency of the indoor heat exchanger.

[0253] In some embodiments of the present application, the indoor rear air inlet 113 is arranged opposite to the three-section heat exchanger 123, so that the gas flowing from the indoor rear air inlet can directly exchange heat with the three-section heat exchanger 123, thereby improving the heat exchange efficiency.

[0254] In some embodiments of the present application, the angles between the one-section heat exchanger 121, the two-section heat exchanger 122 and the three-section heat exchanger 123 and the vertical direction are all less than 40°, so that the indoor heat exchanger 120 can smoothly drain water after installation, and the condensed water can flow down the fins, thereby avoiding the condensed water from dripping from the middle of the fins.

[0255] In some embodiments of the present application, the top of the three-section heat exchanger 123 is not higher than the connection position of the one-section heat exchanger 121 and the two-section heat exchanger 122, which makes the overall structure of the indoor heat exchanger 120 more compact, thereby helping to reduce the volume of the indoor unit 100 while meeting the heat exchange and cross-flow fan installation requirements.

[0256] In some embodiments of the present application, the length of the two-section heat exchanger 122 is greater than the lengths of the one-section heat exchanger 121 and the three-section heat exchanger 123, respectively, which can increase the action area of the air inlet and the indoor heat exchanger 120 as much as possible in the limited inner cavity of the indoor unit 100, thereby improving the heat exchange efficiency.

[0257] [Indoor unit-water pan]

[0258] In some embodiments of the present application, 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, a filter part 500 is arranged at the position where the inner water tank 422 and the outer water tank 421 are communicated, the water receiving area 410 is communicated with the outer water tank 421, and the first water drainage pipeline section 810 is communicated with the inner water tank 422.

[0259] 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 in sequence.

[0260] The outer water tank 421 mainly plays a role in sedimentation of dust particles and dirt in the condensed water.

[0261] Because the water storage area of the outer water tank 421 is large, the water level rises slowly during the storage of the condensed water, so the dust particles and dirt in the condensed water have sufficient time to settle at the bottom of the outer water tank.

[0262] The condensed water is preliminarily settled in the outer water tank 421 and then is filtered in the filtering part 500, so that the fine dust particles in the condensed water are treated again and are isolated in the outer water tank 421.

[0263] 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 impurities blocking the drainage pipeline and the drainage pump when the drainage pump 700 is pumping.

[0264] 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.

[0265] 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 blockage gap of the drainage pipeline and the drainage pump, and reduces the maintenance cost of the drainage pump.

[0266] When the machine is used for a period of time, the user can pull out the water plug structure on the outer water tank 421, and the water in the outer water tank 421 flows out from the water plug 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.

[0267] 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.

[0268] 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.

[0269] 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.

[0270] 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 for the condensed water in the outer water tank to flow is formed between the side wall of the inner water tank 422 and the side wall of the outer water tank 421, and the filtering part 500 is arranged at one end of the water flow channel.

[0271] 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.

[0272] 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.

[0273] In some embodiments of the present application, in combination with Figure 18 and Figure 19 The water collection area 420 is arranged at one side of the side corner of the water pan 400, and one end of the water flow channel extends to the side wall of the water pan 400.

[0274] 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 sink 422. 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.

[0275] The condensed water in the outer sink 421 is filtered by the filter part 500 and then flows into the inner sink 422 through the second water outlet 424.

[0276] After the machine runs for a period of time, the user can remove the blocking part 430, and the condensed water in the outer sink 421 can be discharged through the first water outlet 423, so that the dust particles and dirt in the outer sink 421 can be completely discharged.

[0277] The filter part 500 is removed, and the condensed water in the inner sink 422 can be discharged through the second water outlet 424 and the first water outlet 423.

[0278] 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 sink 421 and the inner sink 422 can be completely discharged.

[0279] The first water outlet 423 is arranged at one end of the outer sink 421, and the second water outlet 424 is arranged at one end of the inner sink 422. When discharging water, the condensed water in the sink flows from one end to the other end, which also plays a certain flushing effect on the inner wall of the sink.

[0280] 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 sink 421 and the inner sink 422 through the inner cavity of the filter part 500.

[0281] In the process of flowing from the outer sink 421 to the inner sink 422 through the inner cavity of the filter part 500, the condensed water in the outer sink 421 is automatically filtered again.

[0282] 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.

[0283] 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 sink 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.

[0284] The outer side of the mounting column 440 is detachably provided with a blocking part 430 to block the through hole. Specifically, the outer periphery of the mounting column 440 is provided with external threads, and the blocking part 430 is in the form of a plug cap structure, and the inner periphery of the blocking part 430 is provided with internal threads. The blocking part 430 is screwed onto the mounting column 440.

[0285] When the filter part 500 needs to be disassembled, the blocking 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.

[0286] 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.

[0287] 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.

[0288] 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.

[0289] 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.

[0290] The structure of the water storage 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.

[0291] 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.

[0292] 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.

[0293] In some embodiments of the present application, the side edges of the outer water tank 421 are provided with a plurality of spaced-apart water distribution ribs 411 at the position communicating 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 411, which plays a role in uniform flow of condensed water.
