[0089] [The saddle type air conditioner]

[0090] 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.

[0091] 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.

[0092] When the saddle type air conditioner is installed on a window, the saddle bridge structure 300 is directly placed on the window, the indoor unit 100 is located at the indoor side, and the outdoor unit 200 is located at the outdoor side.

[0093] 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 existing integrated window air conditioner is installed.

[0094] The indoor unit 100 and the outdoor unit 200 are separated by the saddle bridge structure 300, which helps to avoid the noise of the outdoor unit 200 from being transmitted to the indoor side, and improves the user's comfort.

[0095] The indoor unit 100 mainly comprises a casing, an indoor heat exchanger, a water collecting tray, a cross-flow fan, an air duct and the like, and heat exchange pipelines are arranged between the indoor heat exchanger, the outdoor heat exchanger and the compressor.

[0096] The outdoor unit 200 mainly comprises a casing, an outdoor heat exchanger, an axial flow fan, a compressor 220, a drainage pump 700 and the like. The indoor water collecting tray and the outdoor drainage pump 700 are connected by a drainage pipeline 800 to drain the condensate water in the indoor water collecting tray to the outdoor side.

[0097] [Indoor side air inlet and outlet]

[0098] 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.

[0099] In some embodiments of the application, the indoor unit 100 has an air inlet and outlet mode, referring to Figure 2 , the front side and the back side of the indoor unit 100 are air inlets, and the top is an air outlet.

[0100] 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.

[0101] 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, and then flows out from the indoor top air outlet 111.

[0102] The gap between the rear back plate of the indoor unit 100 and the indoor side wall provides the possibility of backside air inlet of the indoor unit 100.

[0103] The front side and the back side of the indoor unit 100 simultaneously take in air, and compared with the existing window unit, the air inlet amount is significantly increased, which helps to improve the heat exchange efficiency of the indoor heat exchanger, thereby improving the overall heat exchange efficiency of the unit.

[0104] The front side and the back side simultaneously take in air, which ensures sufficient air inlet amount and cancels the bottom air inlet, thereby solving the problem of the existing technology that the bottom air inlet of the indoor unit increases the wind resistance of the water pan and causes the condensate water to overflow and drop.

[0105] Since the air inlet is not needed to be arranged at the bottom of the indoor unit, a large space is not needed to be reserved between the bottom plate of the indoor unit and the water pan, which helps to reduce the overall height of the indoor unit and reduce the indoor space occupation.

[0106] [Outdoor side air inlet and outlet]

[0107] In some embodiments of the present application, the rear back plate of the outdoor unit 200 has a certain gap with the outdoor side wall.

[0108] In some embodiments of the present application, the air inlet and outlet mode of the outdoor unit 200 is that the left and right sides, the top and the back side of the outdoor unit 200 respectively take in air, and the front side takes out air. Figure 1

[0109] Specifically, the rear back plate 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.

[0110] The 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, and then flows out from the outdoor front air outlet 211.

[0111] In some embodiments of the present application, the bottom of the outdoor unit 200 is provided with a bottom air inlet (not shown).

[0112] The gap between the rear back plate of the outdoor unit 200 and the outdoor side wall provides the possibility of backside air inlet of the outdoor unit 200.

[0113] ​The outdoor unit 200 adopts a four-side air inlet mode, increases the air inlet amount, and helps to improve the heat dissipation efficiency of the outdoor heat exchanger and the heat exchange efficiency of the whole machine.

[0114] The outdoor bottom air inlet can increase the air inlet amount while avoiding the problem of inhaling impurities such as fallen leaves.

[0115] [Anchoring bridge structure]

[0116] In some embodiments of the present application, the anchoring 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 anchoring bridge structure 300, so as to adapt to walls of different thicknesses.

[0129] The saddle bridge structure 300 is fixedly connected to the indoor unit 100 and the outdoor unit 200 through the 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.

[0130] 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 installed saddle type air conditioner and reduce the risk of falling.

[0131] [Installation of sealing part]

[0132] In some embodiments of the present application, the inside of the saddle bridge structure 300 is a through cavity, and a sealing part 400 is arranged in the through cavity to isolate the indoor side from the outdoor side and play a role of temperature isolation and water prevention.

[0133] For example, the outdoor saddle bridge shell 320 is sleeved on the outside of the indoor saddle bridge shell 310.

[0134] When the saddle bridge structure 300 is extended or retracted, the indoor saddle bridge shell 310 and the outdoor saddle bridge shell 320 move relatively, the distance between the indoor unit 10 and the outdoor unit 200 changes, and correspondingly, the heat exchange pipeline 900 and the drainage pipeline 800 inside also change correspondingly in length to adapt to the extension or retraction of the saddle bridge structure 300. The pipe running gap 600 provides installation space for the heat exchange pipeline 900 and the drainage pipeline 800, and at the same time, the sealing part 400 is installed across the inner cavity of the saddle bridge structure 300 to seal most of the inner cavity of the saddle bridge structure 300. After passing through the pipe running gap 600, the heat exchange pipeline 900 and the drainage pipeline 800 are inserted into the heat preservation block, such as heat preservation foam, at the pipe running gap 600 to seal the pipe running gap 600. In this way, the entire inner cavity of the saddle bridge structure 300 is reliably sealed, which ensures the isolation, heat preservation and waterproof of the indoor side and the outdoor side, and does not interfere with the pipe running of the heat exchange pipeline 900 and the drainage pipeline 800.

[0154] [Heat exchange pipeline routing structure]

[0155] In some embodiments of the present application, the heat exchange pipeline 900 of the saddle type air conditioner mainly includes a return air pipe group 910, a supercooling pipe group 920, an exhaust pipe, a water bubble pipe and the like.

[0156] One end of the supercooling pipe group 920 is connected with the liquid inlet end of the evaporator (corresponding to the indoor heat exchanger), and the other end is connected with the water bubble pipe. One end of the return air pipe group 910 is connected with the gas outlet end of the evaporator, and the other end is connected with the suction port of the compressor 220. One end of the exhaust pipe is connected with the gas inlet end of the condenser (corresponding to the outdoor heat exchanger), and the other end is connected with the exhaust port of the compressor 220. One end of the water bubble pipe is connected with the supercooling pipe group 920, and the other end is connected with the liquid outlet end of the condenser.

[0157] Referring to Figure 19 , the return air pipe group 910 includes a first return air pipeline section 911, a second return air pipeline section 912 and a third return air pipeline section 913 which are sequentially connected. The first return air pipeline section 911 is connected with the indoor heat exchanger 120, the third return air pipeline section 913 is connected with the compressor 220, and the second return air pipeline section 912 is in a U-shaped structure and located in the inner cavity of the saddle bridge structure 300.

[0158] The three-section structure of the return air pipe group 910 facilitates processing and improves the process level.

[0159] The return air pipe group 910 adopts a copper pipe to avoid leakage of refrigerant.

[0160] When the saddle bridge structure 300 is stretched, the second return air pipeline section 912 in the U-shaped structure plays a certain buffering role for the pipeline stretching, and meets the stretching function of the saddle bridge structure 300.

[0161] 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. When the semicircular structure of the second return gas pipeline section 912 is under stress, the forces on the circular arc structure will cancel each other out in the transmission, thus playing a role in shock absorption. At the same time, the arc-shaped form of the pipeline is designed. Compared with the square or similar square pipeline form, the semicircular structure form uses less pipeline under the same space, thus reducing the cost of the pipeline to a certain extent.

[0162] In some embodiments of the present application, the second return gas pipeline section 912 is arranged in the pipeline space 600 between the sealing component 400 and the inner cavity side wall of the saddle bridge structure 300, and horizontally surrounds one end of the sealing component 400, thereby making full use of the internal space of the saddle bridge structure 300 to realize the pipeline arrangement.

[0163] The sealing component 400 is located in the space surrounded by the U-shaped structure of the second return gas pipeline section 912. When the saddle bridge structure 300 is stretched, the left and right sides of the sealing component 400 can have sufficient excess to ensure that the pipeline does not contact the sealing component during the pulling process.

[0164] In some embodiments of the present application, a spring 914 is arranged 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.

[0165] The second return gas pipeline section 912 is surrounded by a heat insulation sleeve (not shown), which is arranged on the outer periphery of the spring 914 to prevent the second return gas pipeline section 912 from generating condensed water.

[0166] The two ends of the second return gas pipeline section 912 are 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.

[0167] 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.

[0168] The third return gas pipeline U-shaped section 9132 plays a role in auxiliary stretching deformation and can bear a small part of the stretching force, thus playing a buffering role. Avoiding the compressor 220 being directly connected to generate a transverse force on the compressor, which affects the performance and vibration of the compressor.

[0169] In some embodiments of the present application, the plane in which the U-shaped section 9132 of the third return gas pipeline is located is parallel to the central axis of the compressor 220, further playing a role in reducing vibration.

[0170] 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 structure, so that the return gas pipeline does not generate tensile force on other pipelines when being stretched, avoiding deformation or breakage of the pipeline.

[0171] In some embodiments of the present application, referring to Figure 20 , the supercooling pipe group 920 passes through the saddle bridge structure, and the 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 return gas pipeline section 912, ensuring the consistency of the whole machine pulling.

[0172] The supercooling pipe group 920 is sleeved with a heat shrink tube to avoid condensate water and direct contact with other pipelines.

[0173] In some embodiments of the present application, referring to Figure 20 , 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, and the supercooling pipe third section 924 extends horizontally along the bottom plate of the outdoor unit.

[0174] The supercooling pipe group 920 and the return gas pipe group 910 do not interfere with each other, and the structure is compact.

[0175] In some embodiments of the present application, referring to Figure 11 , the compressor 220 is installed at a corner of the outdoor unit 200, and correspondingly, the third return gas pipeline section 913 and the compressor 220 are located on the same side of the inner cavity of the outdoor unit 200, and the third drain pipeline section 830 is located on the other side of the inner cavity of the outdoor unit, that is, the third return gas pipeline section 913 and the third drain pipeline section 830 in the outdoor unit are arranged oppositely and do not interfere with each other.

[0176] The second drain pipeline section 820 and the second return gas pipeline section 912 are bundled together at one or two places by a binding wire, but cannot be tightly bound to prevent the drain pipeline from being flattened, only to play a limiting role.

[0177] Corresponding to the stretching structure of the saddle bridge structure, the length of the return gas pipe group 910 and the supercooling pipe group 920 is increased compared with the conventional window unit, and in some embodiments of the present application, the return gas pipe group 910 and the supercooling pipe group 920 are both provided with an evacuation pipe, and two evacuation points are used to simultaneously evacuate the heat exchange pipeline, improving the evacuation efficiency and production efficiency.

[0178] In some embodiments of the present application, the first evacuation pipe 931 is arranged on the third gas return pipe section 913, specifically on the second third gas return pipe section 9132, and the two are welded, which facilitates processing.

[0179] In some embodiments of the present application, the second evacuation pipe 932 is arranged on the position of the supercooling pipe group 920 close to the outdoor heat exchanger, specifically on the third supercooling pipe section 924, which facilitates production and processing.

[0180] In some embodiments of the present application, the first evacuation pipe 931 can also be arranged on the exhaust pipe.
