Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more particularly to a saddle-type air conditioner. Background Technology

[0002] Most window air conditioners on the market are square in shape and are integrated units, consisting of a chassis, casing, panel, air duct, indoor fan, outdoor fan, motor, compressor, condenser, evaporator, etc. After installation, the height of the sun blockage is approximately the total height of the window air conditioner, preventing customers from enjoying sufficient sunlight. Because the outdoor and indoor parts of a window air conditioner are a single unit, noise generated by the outdoor part will also be transmitted into the room, resulting in very loud noise and affecting customer comfort, making it unsuitable for customers who are sensitive to noise.

[0003] To address this issue, the saddle-type air conditioner was developed. It mainly consists of an indoor section and an outdoor section, separating the two effectively to reduce indoor noise. The indoor and outdoor sections are connected by a saddle-shaped structure. The indoor section mainly includes components such as a panel, casing, chassis, indoor heat exchanger, cross-flow fan, motor, air duct, and electrical control components. The outdoor section mainly includes components such as a casing, chassis, compressor, outdoor heat exchanger, piping, motor, motor bracket, and axial fan.

[0004] In saddle-type air conditioners, the outdoor and indoor units are separated by a saddle bridge structure. This saddle bridge structure needs to handle some of the piping and wiring. Therefore, achieving proper sealing and isolation between the outdoor and indoor units while managing piping and wiring is crucial. Currently, there is a lack of relevant technological research in this area, resulting in saddle-type window air conditioners being noisy and providing a poor user experience.

[0108] The indoor saddle axle shell 310 and the outdoor saddle axle shell 320 are nested together, and the two can move relative to each other to realize the expansion and contraction of the saddle axle structure 300.

[0109] In one specific embodiment, the outdoor axle housing 320 is fitted onto the outside of the indoor axle housing 310, such as... Figure 4 As shown.

[0110] In some embodiments of this application, a sliding part is provided between the indoor saddle housing 310 and the outdoor saddle housing 320 to make the sliding movement between the indoor saddle housing 310 and the outdoor saddle housing 320 more reliable and smooth.

[0111] The sliding part can be a slide rail structure, or a slide channel or slider structure located between the two.

[0112] When the sliding part adopts the slide rail 340, and the outdoor saddle axle housing 320 is fitted on the outside of the indoor saddle axle housing 310, refer to Figure 5 The outer rail 341 of the slide rail is fixedly connected to the inner wall of the outdoor saddle axle housing 320, and the inner rail 342 of the slide rail is fixedly connected to the outer wall of the indoor saddle axle housing 310.

[0124] The vertical part 3212 of the L-shaped base plate of the outdoor saddle axle is the outdoor vertical part mentioned above, which constitutes the rear panel of the outdoor unit 200. (Refer to...) Figure 14 The vertical part 3212 of the outdoor saddle bridge L-shaped base plate is fixedly connected to the base plate of the outdoor unit 200.

[0125] A ventilation opening is provided on the vertical part 3212 of the outdoor saddle bridge L-shaped base plate, which is the outdoor rear air inlet 213.

[0126] An outdoor saddle bridge reinforcing plate 324 is provided at the junction of the horizontal part 3221 and the vertical part 3222 of the outdoor saddle bridge L-shaped base plate to further improve the structural strength of the outdoor saddle bridge L-shaped base plate 321.

[0127] [Saddle Bridge Structure - Saddle Bridge Cover]

[0128] In some embodiments of this application, reference is made to Figure 3 and Figure 4 The saddle-type air conditioner also includes a saddle cover 330, which is fixedly connected to the outermost of the indoor saddle cover 310 and the outdoor saddle cover 320. In this embodiment, the saddle cover 330 is connected to the outdoor saddle cover 320.

[0129] When the indoor saddle housing 310 and the outdoor saddle housing 320 move away from each other, the saddle cover 330 blocks the inner one of the indoor saddle housing 310 and the outdoor saddle housing 320. In this embodiment, the saddle cover 330 blocks the indoor saddle housing 310.

[0130] When the saddle bridge structure is 300mm unstretched, refer to Figure 1 and Figure 2 The saddle cover 330 covers both the indoor saddle cover 310 and the outdoor saddle cover 320.

[0131] When the saddle bridge structure is stretched by 300, refer to Figure 3 and Figure 4 The indoor axle housing 310 will be exposed, and at this time the axle cover 330 will cover the exposed indoor axle housing 310.

[0132] Regarding the specific structure of the bridge cover 330, in some embodiments of this application, the bridge cover 330 includes a top plate 331 and a side plate 332. The top plate 331 covers the top of the bridge structure 300, and the side plate 332 covers the sides of the bridge structure 300.

[0133] The saddle axle cover side panel 332 has an L-shaped structure. The horizontal part 3321 of the saddle axle cover side panel covers the side of the saddle axle structure 300. The vertical part 3322 of the saddle axle cover side panel is fixedly connected to the side panel of the indoor unit 100, forming part of the side of the indoor unit 100, and at the same time realizing the fixed installation of the saddle axle cover 330 on the indoor unit 100.

[0134] In some embodiments of this application, reference is made to Figure 3 and Figure 7 The transverse portion 3321 of the saddle axle cover side plate is provided with a protrusion 333 protruding inward. The protrusion 333 is fixedly connected to the outermost one of the indoor saddle axle cover 310 and the outdoor saddle axle cover 320 by a connector (such as a screw), so as to realize the positioning of the indoor saddle axle cover 310 and the outdoor saddle axle cover 320 after relative movement to the required position.

[0135] Taking the outdoor saddle housing 320 being fitted onto the outside of the indoor saddle housing 310 as an example, after the saddle structure 300 is stretched into place, the saddle cover 330 is fixedly connected to the outdoor saddle housing 320. Since both the indoor saddle housing 310 and the saddle cover 330 are fixedly connected to the indoor unit 100, and the outdoor saddle housing 320 is fixedly connected to the outdoor unit 200, the saddle structure 300 is thus fixedly positioned at a fixed location.

[0136] The protrusion 333 creates a recess on the outer surface of the saddle cover 330, allowing the screw to be embedded in the recessed structure, thus preventing the outer end face of the screw from protruding out of the saddle cover 330 and scratching the user.

[0137] [Saddle Bridge Sealing and Sound Insulation Structure]

[0138] In some embodiments of this application, reference is made to Figures 14 to 16An electrical box 600 is installed inside the cavity of the saddle structure 300. The upper side of the electrical box 600 is close to the top wall of the cavity of the saddle structure 300, and the lower side of the electrical box 600 is close to the bottom wall of the cavity of the saddle structure 300. Taking the outdoor saddle shell 320 being fitted onto the outside of the indoor saddle shell 310 as an example, the upper side of the electrical box 600 is close to the top plate of the indoor saddle shell 310, and the lower side of the electrical box 600 is close to the bottom plate of the indoor saddle shell 310.

[0139] There is a gap between the electrical box 600 and the side wall of the saddle structure 300, and a sealing and sound insulation part (not shown) is provided in the gap. The drain pipe 800 and heat exchange pipe 900 of the air conditioner pass through the sealing and sound insulation part.

[0140] The electrical box 600 and the sealing and sound insulation part together constitute the internal sealing and sound insulation structure of the saddle structure 300. The indoor unit 100 and the outdoor unit 200 are completely separated by the electrical box 600 and the sealing and sound insulation part, which greatly improves the overall sound insulation effect of the air conditioner and effectively prevents water from flowing from the outdoor side to the indoor side. The location of the electrical box 600 makes full use of the internal space of the saddle structure 300, making the overall structure more compact. The sealing and sound insulation part wraps the drain pipe 800 and the heat exchange pipe 900, protecting the pipes to the maximum extent and reducing friction and interference.

[0141] In this embodiment, the saddle bridge structure 300 not only connects the indoor unit 100 and the outdoor unit 200, but also serves to install the electrical box 600, run pipes, and route cables. It integrates multiple functions and has a more compact structure.

[0142] In some embodiments of this application, the electrical box 600 is laterally disposed within the inner cavity of the saddle structure 300. One side of the electrical box 600 is in close contact with one side wall of the inner cavity of the saddle structure 300, and a gap for pipe routing is provided between the other side of the electrical box 600 and the other side wall of the inner cavity of the saddle structure 300. This laterally disposed arrangement of the electrical box 600 makes full use of the internal space of the saddle structure 300 and improves the sound insulation and sealing effect.

[0143] In some embodiments of this application, the sealing and sound insulation part is sound insulation cotton or injection-molded structural parts, which are easy to process and install and have low cost.

[0144] Electrical box installation

[0145] In some embodiments of this application, one side of the electrical box 600 has an inclined wall 610, which is inclined in the vertical plane to avoid the heat exchange pipe 900 and the drainage pipe 800 when the saddle bridge structure 300 extends or retracts, so as to avoid interference with the heat exchange pipe 900 and the drainage pipe 800 when the saddle bridge structure 300 extends or retracts.

[0146] In some embodiments of this application, taking the outdoor saddle housing 320 being fitted onto the outside of the indoor saddle housing 310 as an example, the electrical box 600 is fixedly mounted on the transverse portion 3111 of the L-shaped base plate of the indoor saddle. The top of the electrical box 600 is open, which facilitates the installation of internal electrical components. The top opening of the electrical box 600 is sealed by the indoor saddle cover plate 312.

[0147] In some embodiments of this application, a buffer sealing part 315 is provided at the position where the electrical box 600 contacts the inner wall of the cavity forming the saddle bridge structure 300. The buffer sealing part 315 serves to reduce vibration and prevents condensation on the inner wall of the saddle bridge structure 300 from dripping into the interior of the electrical box 600, thereby improving the waterproof performance of the electrical box 600.

[0148] As a specific embodiment, refer to Figure 10 and Figure 16 The inner side of the indoor saddle bridge cover plate 312 is provided with a buffer sealing part 315, as shown in the reference. Figure 10 The sealing buffer part 315 fits and seals against the top of the electrical box 600, and completely covers the top opening of the electrical box 600.

[0149] The open top structure of the electrical box 600 facilitates the installation of electrical components inside the electrical box 600. The inner wall of the saddle structure 300 (specifically the indoor saddle cover plate 312) serves as the top cover of the electrical box 600, simplifying the structure and reducing costs.

[0150] In some embodiments of this application, the top opening of the electrical box 600 is provided with a flange 620. The flange 620 extends outward from the electrical box 600 and abuts against the buffer sealing part 315, thereby increasing the contact area between the electrical box 600 and the buffer sealing part 315 and improving the sealing effect.

[0151] In some embodiments of this application, reference is made to Figures 16 to 18 The power cord 400 is led out from the inside of the electrical box 600 and extends towards the indoor unit. The casing of the indoor unit 100 is provided with a wire hole 120, through which the power cord 400 passes to connect to the indoor power socket.

[0152] The power cord routing structure makes full use of the internal space of the saddle bridge structure 300, making the power cord routing simple and convenient.

[0153] In some embodiments of this application, reference is made to Figure 2 and Figure 17The wiring hole 120 is located on the side and rear of the indoor unit 100. The power cord 400, which is led out from the electrical box 600, passes through the inner cavity of the indoor unit 100 in the shortest possible distance, reducing the length of the internal wiring and making the interior of the air conditioner more neat and compact. At the same time, after the power cord 400 is led out from the rear of the indoor unit 100, it can continue to extend along the indoor wall to connect to the power plug, which also facilitates indoor wiring and makes the wiring more aesthetically pleasing.

[0154] In some embodiments of this application, reference is made to Figure 17 and Figure 19 The power cord 400 has a wire fixing part 630 on the path extending from the power supply box 600 to the wire hole 120, which improves the wiring reliability of the power cord 400.

[0155] The cable fixing part 630 is an arch bridge-type cable clamp structure, and both ends are fixed to the bottom wall of the saddle bridge structure 300 by screws. The middle protruding structure of the cable fixing part 630 and the bottom wall of the saddle bridge structure 300 define a cable routing hole, through which the power cable 400 passes.

[0156] In some embodiments of this application, the power cord 400 leading out from the electrical box 600 first extends horizontally along the bottom of the inner cavity of the saddle bridge structure, and then extends vertically along the rear wall of the inner cavity of the indoor unit 100 to the wire hole 120.

[0157] The power cord 400 is routed close to the inner wall of the saddle structure 300 and the indoor unit 100, without interfering with the installation and layout of other internal components (such as the drain pipe 800 and the heat exchange pipe 900).

[0158] Taking the outdoor saddle housing 320 being fitted onto the outside of the indoor saddle housing 310 as an example, the electrical box 600 is fixedly mounted on the horizontal part 3112 of the indoor saddle L-shaped base plate, and the power cord 400 extends along the horizontal part 3111 of the indoor saddle L-shaped base plate towards the vertical part 3112, and then extends along the vertical part 3112 of the indoor saddle L-shaped base plate to the wire hole 120.

[0159] Reference Figure 6 The side of the saddle bridge cover 330 is provided with a clearance hole 334 that is directly opposite to the wire hole 120 so that the power line 400 can pass through smoothly.

[0160] [Saddle Bridge Waterproof Structure]

[0161] In some embodiments of this application, the outdoor saddle axle housing 310 is fitted onto the outside of the indoor saddle axle housing 320, as shown in the reference. Figure 4 and Figure 9 The top plate of the indoor saddle axle housing 310 is provided with a recess for water storage; see reference. Figure 11 and Figure 23 The top plate of the outdoor saddle axle shell 320 is equipped with a water-blocking flange, and a drainage section is provided on the water-blocking flange.

[0162] After the saddle structure 300 is stretched, the outdoor saddle shell 320 is exposed. Rainwater will first drip onto the top plate of the outdoor saddle shell 320. The water-blocking flange collects the water. Then, the rainwater is discharged to the outdoor unit side through the drainage section. If a small amount of rainwater seeps into the top plate of the indoor saddle shell 310, this small amount of rainwater will be temporarily stored in the recess. The recess acts as a buffer to store the small amount of rainwater that seeps in, preventing rainwater from seeping into the indoor side.

[0163] In some embodiments of this application, the recess includes a first recess 316, which is a rectangular recessed structure that covers the top opening of the electrical box 600.

[0164] While temporarily storing rainwater, the first recess 316's downward-recessed structure also improves the sealing between the top plate of the indoor saddle housing 310 and the electrical box 600.

[0165] In some embodiments of this application, reference is made to Figure 10 and Figure 16 The first recess 316 has a buffer sealing part 315 on the inner cavity side facing the indoor saddle housing 310. The buffer sealing part 315 completely covers the top opening of the electrical box 600, further improving the sealing effect of the electrical box 600 and preventing condensate from dripping into the interior of the electrical box 600.

[0166] In some embodiments of this application, the recess further includes an L-shaped second recess 317, which surrounds the first recess 316. While improving the water storage capacity at the top of the indoor saddle housing 310, the concave shape also helps to improve the structural strength.

[0167] In some embodiments of this application, the drainage section is provided on the side of the outdoor saddle cover 322 near the casing of the outdoor unit 200, so that water is discharged to the outdoor side.

[0168] In some embodiments of this application, reference is made to Figure 23 The water-blocking flange is provided on the circumferential side of the outdoor saddle bridge cover plate 322, including a first water-blocking flange 511, a second water-blocking flange 512, a third water-blocking flange 513 and a fourth water-blocking flange 514 arranged sequentially along the circumference of the cover plate.

[0169] The first water-blocking flange 511 is close to the outdoor unit 200 and is fixedly connected to the casing of the outdoor unit 200. The first water-blocking flange 511 is provided with a first drainage part 521, through which water is discharged to the outdoor side.

[0170] In some embodiments of this application, reference is made to Figure 24 and Figure 25The first drainage section 521 has an open structure, and a water guide section 530 extending downward from the cover plate is provided at the open structure to guide the water and prevent the water from splashing everywhere when it flows downward from the opening of the first drainage section 521.

[0171] In some embodiments of this application, the water guiding part 530 includes a main water plate 531 and side water guiding plates 532 disposed on the left and right sides of the main water plate 531. The distance between the two side water guiding plates 532 gradually decreases from the cover plate downwards, forming a structure similar to a winnowing basket, which has a good effect on the convergence and guiding of water flow.

[0172] In some embodiments of this application, reference is made to Figure 23 A gap exists between one end of the second water-blocking flange 512 and one end of the first water-blocking flange 511, forming a second drainage section 522, and / or a gap exists between one end of the fourth water-blocking flange 514 and the other end of the first water-blocking flange 511, forming a second drainage section 522.

[0173] The second drainage section 522 is an opening structure formed on the left and right sides of the cover plate, which increases the number of drainage outlets on the cover plate, improves the drainage effect, and prevents water from being unable to drain in time and accumulating on the cover plate and flowing back into the room.

[0174] The first drainage section 521 and the second drainage section 522 greatly improve the drainage efficiency of the saddle bridge structure 300, and no additional components are required. Only a drainage outlet structure needs to be opened on the saddle bridge structure 300, which is convenient for processing and manufacturing and has low cost.

[0175] Furthermore, the drainage structure will not affect the extension and retraction of the saddle bridge structure 300, and will not have a negative impact on the overall function of the machine.

[0176] [Heat exchange piping structure]

[0177] In some embodiments of this application, the heat exchange pipeline 900 of the saddle-type air conditioner mainly includes a return gas pipeline group 910, a subcooling pipeline group 920, an exhaust pipe, and a water-soaking pipe, etc.

[0178] One end of the subcooling pipe assembly 920 is connected to the liquid inlet of the evaporator (corresponding to the indoor heat exchanger), and the other end is connected to the water soaking pipe; one end of the return gas pipe assembly 910 is connected to the gas outlet of the evaporator, and the other end is connected to the suction port of the compressor; one end of the exhaust pipe is connected to the gas inlet of the condenser (corresponding to the outdoor heat exchanger), and the other end is connected to the exhaust port of the compressor; one end of the water soaking pipe is connected to the subcooling pipe assembly 920, and the other end is connected to the liquid outlet of the condenser.

[0179] Reference Figure 21The return air pipe assembly 910 includes a first return air pipe section 911, a second return air pipe section 912, and a third return air pipe section 913 connected in sequence. The first return air pipe section 911 is connected to the indoor heat exchanger 120, the third return air pipe section 913 is connected to the compressor 220, and the second return air pipe section 912 has a U-shaped structure and is located in the inner cavity of the saddle bridge structure 300.

[0180] The three-section structure of the 910 return air pipe assembly facilitates processing and improves the level of technology.

[0181] The return gas pipe assembly 910 uses copper pipes to prevent refrigerant leakage.

[0182] When the saddle bridge structure 300 is stretched, the U-shaped second return air pipe section 912 provides a certain amount of buffer for the pipe stretching, thus satisfying the expansion and contraction function of the saddle bridge structure 300.

[0183] In some embodiments of this application, the U-shaped structure of the second return air pipe section 912 is a semi-circular structure. When the whole machine is running, the vibration of the pipe is actually the transmission of force. When the semi-circular structure of the second return air pipe section 912 is subjected to force, the forces on the arc structure will cancel each other out during transmission, thus playing a role in shock absorption. At the same time, the arc shape of the pipe design, compared with the square or similar square pipe shape, requires less pipe in the same space, which reduces the pipe cost to a certain extent.

[0184] In some embodiments of this application, the second return gas pipe section 912 passes through the gap between the electrical box 600 and the inner cavity sidewall of the saddle structure 300, and horizontally surrounds one side of the electrical box 600, making full use of the internal space of the saddle structure 300 to realize pipe routing.

[0185] The electrical box 600 is located within the space enclosed by the U-shaped structure of the second return air pipe section 912. When the saddle bridge structure 300 is stretched, there is enough leeway on both sides of the electrical box 600 to ensure that the pipe does not come into contact with the electrical box 600 during the pulling process.

[0186] In some embodiments of this application, a spring 914 is fitted on the second return air pipe section 912 to prevent the second return air pipe section 912 from being flattened or collapsed during the stretching process.

[0187] The outer periphery of the second return gas pipe section 912 is covered with a heat insulation sleeve (not shown). The heat insulation sleeve covers the outer periphery of the spring 914 to prevent condensation from forming on the second return gas pipe section 912 and flowing into the electrical box 600.

[0188] The two ends of the second return air pipe section 912 are flared, which serves to connect with the first return air pipe section 911 and the third return air pipe section 913, and also to limit the spring.

[0189] In some embodiments of this application, the third return gas pipeline section 913 includes a third return gas pipeline section 1 9131, a third return gas pipeline U-shaped section 9132, and a third return gas pipeline section 2 9133 connected in sequence. The opening of the third return gas pipeline U-shaped section 9132 faces upward. The third return gas pipeline section 1 9131 is connected to the second return gas pipeline section 912, and the third return gas pipeline section 2 9133 is connected to the suction port of the compressor 220.

[0190] The U-shaped section 9132 of the third return gas pipeline plays an auxiliary role in tensile deformation, and can bear a small part of the tensile force, thus acting as a buffer to avoid the compressor being subjected to a lateral force after being directly connected to the compressor 220, which would cause the compressor to be subjected to stress and affect its performance and vibration.

[0191] In some embodiments of this application, the plane of the U-shaped section 9132 of the third return gas pipeline is parallel to the central axis of the compressor 220, which further reduces vibration.

[0192] The first return gas pipe section 911 and the third return gas pipe section 913 are fixed to the back panel of the indoor unit and the outdoor unit with binding wires or other structures, so that when the return gas pipe is stretched, it will not exert tensile force on other pipes, thus avoiding pipe deformation or breakage.

[0193] In some embodiments of this application, reference is made to Figure 22 The subcooling pipe assembly 920 passes through the saddle bridge structure. The subcooling pipe assembly 920 is equipped with a U-shaped section 921. 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 pipe section 912 to ensure the consistency of the whole machine's pull-out.

[0194] Heat shrink tubing is fitted onto the subcooling tube assembly 920 to prevent condensate from flowing into the electrical box 600 and to avoid direct contact with other pipes.

[0195] In some embodiments of this application, reference is made to Figure 22 The subcooling pipe assembly 920 also includes a first subcooling pipe section 922, a second subcooling pipe section 923, and a third subcooling pipe section 924 connected in sequence. The first subcooling pipe section 922 extends horizontally along the upper part of the rear panel of the outdoor unit to connect with the U-shaped section 921 of the subcooling pipe assembly. The second subcooling pipe section 923 extends vertically along the side of the rear panel of the outdoor unit to the chassis of the outdoor unit. The third subcooling pipe section 924 extends horizontally along the chassis of the outdoor unit.

[0196] The wiring of the subcooling pipe assembly 920 and the return gas pipe assembly 910 does not interfere with each other, resulting in a compact structure.

[0197] In some embodiments of this application, reference is made to Figure 14The compressor 220 is installed at one corner of the outdoor unit 200. Correspondingly, the third return gas pipe 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 pipe section 830 is located on the other side of the inner cavity of the outdoor unit. That is, the third return gas pipe section 913 and the third drain pipe section 830 in the outdoor unit are arranged opposite each other and do not interfere with each other.

[0198] The second drainage pipe section 820 and the second return gas pipe section 912 are tied together with a binding wire at one or two points, but not tightly, to prevent the drainage pipe from being flattened; the binding only serves as a limit.

[0199] [Evacuation of heat exchange pipelines]

[0200] Corresponding to the tension structure of the saddle bridge, the lengths of the return air pipe group 910 and the subcooling pipe group 920 are increased compared to conventional window air conditioners. In some embodiments of this application, the return air pipe group 910 and the subcooling pipe group 920 are equipped with evacuation pipes, and the heat exchange pipeline is evacuated at two evacuation points at the same time, thereby improving evacuation efficiency and production efficiency.

[0201] In some embodiments of this application, the first evacuation pipe 931 is disposed on the third return gas pipe section 913, specifically on the second section 9132 of the third return gas pipe, and the two are welded together for easy processing.

[0202] In some embodiments of this application, a second evacuation pipe 932 is provided at the position of the subcooling pipe assembly 920 near the outdoor heat exchanger. Specifically, the second evacuation pipe 932 is provided on the three sections of the subcooling pipe 924, which facilitates production and processing.

[0203] In some embodiments of this application, the first evacuation pipe 931 may also be disposed on the exhaust pipe.

[0204] Drainage pipe routing structure

[0205] In some embodiments of this application, reference is made to Figure 14 The outdoor unit 200 is equipped with a drain pump 700, and the bottom of the indoor unit 100 is equipped with a drip tray for collecting condensate produced by the indoor evaporator. The drain pump 700 and the drip tray are connected by a drain pipe 800 to drain the indoor condensate.

[0206] The drain pipe 800 is led out from the indoor water receiving pan, passes through the inner cavity of the indoor unit 100, the inner cavity of the saddle structure 300 and the inner cavity of the outdoor unit 200, and is led to the inlet of the drain pump 700.

[0207] The portion of the drainage pipe 800 located within the saddle structure 300 has at least one U-shaped bend. When the saddle structure 300 is stretched, this U-shaped bend acts as a buffer for the pipe's stretching, thus satisfying the expansion and contraction function of the saddle structure 300.

[0208] In some embodiments of this application, reference is made to Figure 20 The drainage pipe 800 includes a first drainage pipe section 810 located in the indoor unit 100, a second drainage pipe section 820 located in the saddle structure 300, and a third drainage pipe section 830 located in the outdoor unit 200, which are connected in sequence. The first drainage pipe section 810 is connected to the water receiving tray, and the third drainage pipe section 830 is connected to the water inlet of the drainage pump 700.

[0209] The second drainage pipe section 820 passes through the gap between the electrical box 600 and the inner wall of the saddle structure 300.

[0210] The second drainage pipe section 820 is provided with a first U-shaped bend section 821, which horizontally surrounds one side of the electrical box 600.

[0211] In some embodiments of this application, the two straight pipe sections of the first U-shaped bend section 821 are located on both sides of the electrical box 600, and the arc-shaped section of the first U-shaped bend section 821 is located on one end of the electrical box 600. When the length of the saddle bridge structure 300 is stretched, the first U-shaped bend section 821 will adapt to the deformation to meet the tensile deformation requirements.

[0212] In some embodiments of this application, the second drainage pipe section 820 is further provided with a second U-shaped bend section 822. The second U-shaped bend section 822 shares a straight pipe section with the first U-shaped bend section 821. The second U-shaped bend section 822 is horizontally located in the inner cavity of the saddle bridge structure 300 and is located on the side of the electrical box 600.

[0213] The second U-shaped bend 822 serves to assist in tensile deformation, ensuring that when the saddle bridge structure 300 is stretched to its maximum length, the drainage pipe 800 still has sufficient length to meet normal drainage requirements.

[0214] In some embodiments of this 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.

[0215] The vertical section 811 of the first drain pipe is connected to the water receiving tray 400. The vertical section 812 of the first drain pipe extends vertically against the back panel of the indoor unit and can be fixed with positioning structures such as clips to improve the stability of the pipe.

[0216] The first drainage pipe horizontal section 812 is connected to the first U-shaped bend section 821 and is located on the side of the electrical box 600 near the indoor unit.

[0217] The arrangement of the first drain pipe section 810 does not affect the installation of other components in the cavity of the indoor unit 100, making full use of the cavity space of the indoor unit and resulting in a compact structure.

[0218] In some embodiments of this application, the outdoor unit 200 is provided with a rear partition for installing components such as a condenser and a fan. A drain pump 700 is disposed on the rear partition, and the third drain pipe section 830 is connected to the second U-shaped bend section 822.

[0219] The installation of the drainage pump 700 makes full use of the existing structure of the outdoor unit, making full use of space and resulting in a compact structure.

[0220] In some embodiments of this application, the third drainage pipe section 830 includes a third drainage pipe vertical section I 831, a third drainage pipe horizontal section 832, and a third drainage pipe vertical section II 833 connected in sequence. The third drainage pipe vertical section I 831 is connected to the second U-shaped bend section 822. The third drainage pipe horizontal section 832 extends along the chassis of the outdoor unit. The third drainage pipe vertical section II 833 extends upward along the rear partition to the inlet of the drainage pump 700.

[0221] The third drainage pipe vertical section II833 can be fixed to the rear partition plate using a clip or other structure to prevent the water pipe from shaking and interfering with the fan.

[0222] The arrangement of the third drainage pipe 830 does not affect the installation of other components in the inner cavity of the outdoor unit 200, making full use of the inner cavity space of the outdoor unit and resulting in a compact structure.

[0223] Indoor unit - indoor side air inlet and outlet]

[0224] In some embodiments of this application, there is a certain gap between the back panel of the indoor unit 100 and the indoor side wall.

[0225] In some embodiments of this application, the air intake and exhaust method of the indoor unit 100 is as follows: (Refer to...) Figure 2 The indoor unit 100 has air intake on the front and back sides and air outlet at the top.

[0226] Specifically, the indoor unit 100 has an indoor front air inlet 112 on the front panel, an indoor rear air inlet 113 on the rear panel, and an indoor top air outlet 111 on the top.

[0227] 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. After heat exchange by the indoor heat exchanger 120, it flows out from the indoor top air outlet 111.

[0228] The gap between the rear panel of the indoor unit 100 and the indoor side wall makes it possible for the indoor unit 100 to have rear-side air intake.

[0229] The indoor unit 100 draws air from both the front and rear sides simultaneously, significantly increasing the air intake compared to existing window units. This helps improve the heat exchange efficiency of the indoor heat exchanger, thereby enhancing the overall heat exchange efficiency of the unit.

[0230] The simultaneous air intake from the front and rear sides ensures sufficient airflow while eliminating bottom air intake, thus solving the problems of increased air resistance in the drip tray and condensate overflow and dripping caused by bottom air intake of the indoor unit in existing technologies.

[0231] Since there is no need to open an air inlet at the bottom of the indoor unit, there is no need to leave too much space between the bottom plate of the indoor unit and the water tray, which helps to reduce the overall height of the indoor unit and reduce the space occupied indoors.

[0232] The indoor unit has a hollowed-out air inlet on the back panel, which, combined with a corresponding concave design, helps to reduce the weight of the indoor unit and also helps to improve the structural strength of the back panel.

[0233] In some embodiments of this application, removable filters (not shown) are provided at the indoor front air inlet 112 and the indoor rear air inlet 113 to filter dust and impurities.

[0234] In some embodiments of this application, the indoor ceiling air outlet 111 is tilted towards the indoor side, which facilitates the flow of heat-exchanged gas towards the indoor side.

[0235] In some embodiments of this application, a pad or adjustable bolt (not shown) is provided between the back panel of the indoor unit 100 and the indoor side wall to improve the installation stability of the indoor unit 100.

[0236] Outdoor unit - outdoor side air inlet and outlet]

[0237] In some embodiments of this application, there is a certain gap between the rear panel of the outdoor unit 200 and the outdoor side wall.

[0238] In some embodiments of this application, the air intake and exhaust method of the outdoor unit 200 is as follows: (Refer to...) Figure 1 The outdoor unit 200 has air intakes on the left and right sides, top and back, and air exhausts from the front.

[0239] Specifically, the outdoor unit 200 has an outdoor rear air inlet 213 on its rear panel, outdoor side air inlets 212 on its left and right side panels, an outdoor top air inlet 214 on its top panel, and an outdoor front air outlet 211 on its front panel.

[0240] Outdoor air flows into the inner cavity of the outdoor unit 200 from the outdoor rear air inlet 213, the outdoor side air inlet 212, and the outdoor top air inlet 214. After heat exchange by the outdoor heat exchanger 230, it flows out from the outdoor front air outlet 211.

[0241] In some embodiments of this application, the outdoor unit 200 is provided with a bottom air inlet (not shown).

[0242] The gap between the rear panel of the outdoor unit 200 and the outdoor side wall makes it possible for the outdoor unit 200 to have rear-side air intake.

[0243] The outdoor unit 200 adopts a four-sided air intake method, which increases the air intake volume and helps to improve the heat dissipation efficiency of the outdoor heat exchanger and improve the overall heat exchange efficiency of the unit.

[0244] The outdoor unit 200 has perforated air inlets on its back panel and bottom panel, with corresponding concave designs, which helps to reduce the weight of the outdoor unit and also helps to improve the structural strength of the back panel and bottom panel.

[0245] The outdoor rear air inlet 213 is directly opposite the axial fan 250 inside the outdoor unit, which greatly enhances the ability of the outdoor axial fan 250 to draw in air from the outside when it is running, and improves the heat dissipation effect of the airflow on the outdoor heat exchanger.
