[0093] [Saddle-type air conditioner]

[0094] This embodiment discloses a saddle-shaped air conditioner, referring to... Figure 1 It includes an indoor unit 100 located on the indoor side, an outdoor unit 200 located on the outdoor side, and a saddle bridge structure 300 connecting the indoor unit 100 and the outdoor unit 200.

[0095] The inner cavity of the indoor unit 100, the inner cavity of the saddle bridge structure 300, and the inner cavity of the outdoor unit 200 are all connected.

[0096] The saddle-type air conditioner has an N-type structure, with the indoor unit 100 and the outdoor unit 200 located at both ends of the saddle structure 300 and on the same side of the saddle structure 300.

[0097] When the saddle-type air conditioner is installed on the window, the saddle structure 300 sits directly on the window, the indoor unit 100 is located on the indoor side, and the outdoor unit 200 is located on the outdoor side.

[0098] Since both the indoor unit 100 and the outdoor unit 200 are located below the window, this saddle-shaped air conditioner solves the problem of existing integrated window units blocking sunlight after installation.

[0099] By separating the indoor unit 100 from the outdoor unit 200 through the saddle bridge structure 300, it is helpful to prevent the noise of the outdoor unit 200 from being transmitted to the indoor side, thereby improving user comfort.

[0100] The indoor unit 100 mainly includes components such as the casing, indoor heat exchanger, water tray, cross-flow fan, and air duct.

[0101] The outdoor unit 200 mainly includes components such as the casing, outdoor heat exchanger, axial fan, and compressor.

[0102] [Indoor unit - Indoor side air intake and exhaust]

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] [Indoor Unit - Indoor Heat Exchanger]

[0116] In some embodiments of this application, reference is made to Figure 15 and Figure 16 The indoor heat exchanger 120 has a three-section structure, including heat exchanger section 121, heat exchanger section 122 and heat exchanger section 123 connected in sequence.

[0117] Heat exchanger section 121 extends vertically, heat exchanger section 122 extends diagonally downward from the bottom of heat exchanger section 121, and heat exchanger section 123 extends diagonally upward from the bottom of heat exchanger section 122.

[0118] The first heat exchanger 121 and the second heat exchanger 122 are located near the front panel of the indoor unit 100, and the second heat exchanger 122 extends obliquely downward from the bottom of the first heat exchanger 121 in a direction away from the front panel.

[0119] The heat exchanger section 123 is located near the rear panel of the indoor unit 100, and extends obliquely upward from the bottom of the heat exchanger section 122 towards the rear panel.

[0120] The front air inlet flows through heat exchanger section 121 and heat exchanger section 122, while the rear air inlet flows through heat exchanger section 123.

[0121] The cross-flow fan 130 is located within the area enclosed by the three-section indoor heat exchanger, making full use of the internal space of the indoor unit 100, resulting in a compact structure.

[0122] After being heated by heat exchangers 121, 122 and 123, the air is collected and flows out from the top air outlet 111.

[0123] The air intakes on the front and rear sides of the indoor unit are perfectly matched with the three-section indoor heat exchanger, allowing each air intake to fully exchange heat with the indoor heat exchanger, greatly improving the heat exchange efficiency of the indoor heat exchanger.

[0124] In some embodiments of this application, the indoor rear air inlet 113 is arranged directly opposite the heat exchanger section 123, so that the gas flowing in from the indoor rear air inlet can directly exchange heat with the heat exchanger section 123, thereby improving the heat exchange efficiency.

[0125] In some embodiments of this application, the angles between the first section 121, the second section 122, and the third section 123 of the heat exchanger and the vertical direction are all less than 40°, ensuring that the indoor heat exchanger 120 drains smoothly after installation, and that the condensate can flow down the fins, preventing the condensate from dripping from the middle of the fins.

[0126] In some embodiments of this application, the top of the three-section heat exchanger 123 is not higher than the connection position between the first-section heat exchanger 121 and the second-section heat exchanger 122. While meeting the heat exchange requirements and the installation requirements of the cross-flow fan, this makes the overall structure of the indoor heat exchanger 120 more compact and helps to reduce the size of the indoor unit 100.

[0127] In some embodiments of this application, the length of the second section 122 of the heat exchanger is greater than the lengths of the first section 121 and the third section 123 of the heat exchanger, respectively. In the limited internal cavity of the indoor unit 100, the effective area of ​​the air intake and the indoor heat exchanger 120 is maximized to improve the heat exchange efficiency.

[0128] [Indoor unit - drip tray]

[0129] In some embodiments of this application, the indoor unit 100 is provided with a drip tray 400 for holding condensate in its inner cavity.

[0130] Reference Figure 17 The water receiving tray 400 is provided with a water receiving area 410 and a water holding area 420. The water holding 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 provided at the position where the inner water tank 422 and the outer water tank 421 are connected. The water receiving area 410 is connected to the outer water tank 421. The inner water tank 422 is connected to the drain pump 700 through the drain pipe 710.

[0131] The condensate produced 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 section 500.

[0132] The external water tank 421 mainly serves to settle larger dust particles and dirt in the condensate.

[0133] Because the outer water tank 421 has a large water storage area, the water level rises slowly during the condensate storage process. Therefore, the dust particles and dirt in the condensate have enough time to settle to the bottom of the outer water tank on their own.

[0134] After initial sedimentation treatment in the outer water tank 421, the condensate passes through the filter section 500 for secondary treatment of the fine dust particles contained in the condensate, thus isolating the fine dust within the outer water tank 421.

[0135] After secondary treatment, the condensate enters the inner water tank 422. At this point, the condensate has reached a high level of cleanliness, which can effectively prevent impurities from clogging the drainage pipes and the drainage pump when it is pumped by the drainage pump 700.

[0136] The inner water tank 422 is equipped with a float switch (not shown). When the water level in the inner water tank 422 reaches a certain height, the float switch is activated, and the drain pump 700 starts to pump water.

[0137] In this embodiment, the water receiving tray 400 adopts the method of "outer water tank sedimentation and inner water tank filtration", which effectively improves the removal effect of dust and dirt in condensate water, reduces the blockage of drainage pipes and drainage pumps, and reduces drainage pump maintenance costs.

[0138] After the machine has been used for a period of time, the user can remove the water plug structure on the outer water tank 421. The water in the outer water tank 421, driven by gravity, carries the previously deposited mud, sand, dust particles and other debris out from the water plug location, thus achieving a self-cleaning effect.

[0139] In some embodiments of this application, the total area of ​​the water-holding area 420 (outer water tank 421 + inner water tank 422) accounts for about 1 / 6 of the total area of ​​the water receiving tray 400, and the water-holding volume is larger, which can hold more condensate.

[0140] The inner water tank 422 has an area of ​​approximately half that of the entire water-holding area 420, allowing it to hold more clean condensate.

[0141] In some embodiments of this application, a water tank cover (not shown) is provided on the top of the water-holding area 420 to prevent condensate containing dust particles and dirt dripping from the indoor heat exchanger 120 from falling into the water-holding area 420.

[0142] In some embodiments of this application, reference continues to be made to... Figure 17 The inner water tank 422 is located on one side of the outer water tank 421 near the corner. A water flow channel for the condensate in the outer water tank is formed between the side wall of the inner water tank 422 and the side wall of the outer water tank 421. The filter part 500 is located at one end of the water flow channel.

[0143] Water in the outer water tank 421 flows along the water flow channel to the filter section 500, and after filtration, it flows into the inner water tank 422.

[0144] The water flow channel increases the flow distance and time of condensate in the outer water tank 421, which helps to improve the settling effect of dust particles and dirt.

[0145] In some embodiments of this application, combined with Figure 18 and Figure 19 The water-holding area 420 is located on one side of the water receiving tray 400 near the corner, and one end of the water flow channel extends to the side wall of the water receiving tray 400.

[0146] The water receiving tray 400 has a first water inlet 423 on its side wall and a second water inlet 424 on its side wall. The first water inlet 423 and the second water inlet 424 are directly opposite each other. A detachable sealing part 430 is provided at the first water inlet 423.

[0147] The condensate in the outer water tank 421 is filtered by the filter section 500 and then flows into the inner water tank 422 through the second water inlet 424.

[0148] After the machine has been running for a period of time, the user can remove the sealing part 430 himself, and the condensate in the outer water tank 421 can be discharged through the first water inlet 423 to completely remove the dust particles and dirt that have settled in the outer water tank 421.

[0149] Remove the filter section 500, and the condensate in the inner water tank 422 can be discharged through the second water inlet 424 and the first water inlet 423.

[0150] In other words, after the machine has been running for a period of time, the sealing part 430 and the filter part 500 can be removed, and all the water in the outer water tank 421 and the inner water tank 422 can be drained.

[0151] The first water inlet 423 is located at one end of the outer water tank 421, and the second water inlet 424 is located at one end of the inner water tank 422. When draining, the condensate in the water tank flows from one end to the other, which also plays a certain role in rinsing the inner wall of the water tank.

[0152] In some embodiments of this application, one end of the filter section 500 is disposed in the first water inlet 423, thereby sealing the first water inlet 423; the other end of the filter section 500 is disposed in the second water inlet 424, thereby connecting the outer water tank 421 and the inner water tank 422 through the inner cavity of the filter section 500.

[0153] As the condensate in the outer water tank 421 flows through the inner cavity of the filter section 500 into the inner water tank 422, it automatically completes secondary filtration of dust particles.

[0154] The filter unit 500 can be removed from the outside of the water receiving tray 400, making it easy to clean and replace the filter unit 500.

[0155] In some embodiments of this application, the side wall of the water receiving tray 400 is provided with a mounting post 440, and the mounting post 400 is provided with a through hole communicating with the outer water tank 421. One end of the filter part 500 (i.e. the extension part 518) extends into the through hole through the first water inlet 423.

[0156] The mounting post 440 is detachably provided with a sealing part 430 on its outer side to seal the through hole. Specifically, the outer periphery of the mounting post 440 is provided with external threads, and the sealing part 430 is a plug structure with internal threads on its inner periphery. The sealing part 430 is screwed onto the mounting post 440.

[0157] When the filter section 500 needs to be disassembled, first remove the sealing part 430, then pull the extension part 518 by hand to pull out the filter section 500.

[0158] In some embodiments of this application, the sidewall of the outer water tank 421 includes a first outer sidewall 4211, a second outer sidewall 4212, a third outer sidewall 4213, and a fourth outer sidewall 4214 connected in sequence.

[0159] The sidewalls in the inner water tank 422 that form the water flow channel include a first inner sidewall 4221, a second inner sidewall 4222, a third inner sidewall 4223 and a fourth inner sidewall 4224 connected in sequence, and each pair of adjacent sidewalls has an L-shaped structure.

[0160] The first inner wall 4221 is connected to the fourth outer wall 4211, the fourth inner wall 4224 is connected to the third outer wall 4213, and there is a gap between the third inner wall 4223 and the third outer wall 4213 for accommodating the filter section 500.

[0161] The first water inlet 423 is located on the third outer side wall 4213, and the second water inlet 424 is located on the third inner side wall 4223.

[0162] The structure of the water-holding area 420 is designed in this way, so that the water flow channel formed between the outer water tank 421 and the inner water tank 421 is L-shaped. The long and narrow water flow channel is more conducive to the settling of dust particles and dirt.

[0163] The filter unit 500 is located at the corner where the outer water tank 421 and the inner water tank 422 connect. The water flow is buffered at this corner, which helps to improve the secondary filtration effect of dust particles.

[0164] In some embodiments of this application, multiple water-guiding ribs are provided in the water receiving area 410 to guide the flow of condensate.

[0165] In some embodiments of this application, the side of the outer water tank 421 is provided with a plurality of spaced water-dividing ribs 411 at a position communicating with the water receiving area 410. A water flow gap is formed between two adjacent water-dividing ribs 411 to supply water into the outer water tank 421, which plays a role in equalizing the flow of condensate.

[0166] [Indoor Unit - Filter Section]

[0167] Regarding the specific structure of the filter section 500, in some embodiments of this application, the filter section 500 is mainly used to filter dust particles and dirt in the condensate in the water receiving pan 400, so as to prevent the drain pipe and drain pump from becoming blocked.

[0168] The filter unit 500 is detachably installed on the water receiving tray 400, which facilitates the cleaning and replacement of the filter unit 500.

[0169] In some embodiments of this application, reference is made to Figure 18 and Figure 20 The filter unit 500 includes a housing 410, which has a cavity with one end open. The housing 410 has an opening (not shown) communicating with the cavity. A filter screen 520 is provided inside the cavity, and the filter screen 520 covers the opening.

[0170] The condensate in the drip tray 400 enters the cavity through the opening and filter screen 520, and then flows out through the open end, thus achieving the filtration of condensate.

[0171] by Figure 17 Taking the water receiving tray 400 structure shown as an example, the condensate in the outer water tank 421 flows into the internal cavity of the filter section 500 after passing through the opening and the filter screen 520, and then flows into the inner water tank 422.

[0172] In some embodiments of this application, the outer casing 510 includes a first outer casing peripheral wall 511 and a second outer casing peripheral wall 512 arranged at intervals. A plurality of connecting ribs 513 are provided between the first outer casing peripheral wall 511 and the second outer casing peripheral wall 512, and openings are formed between the plurality of connecting ribs 513. The large opening area allows for a larger area of ​​the filter screen 520 that interacts with the condensate, improving the flowability of the condensate and the filtration effect.

[0173] The first outer casing peripheral wall 511 is located inside the first water inlet 423, and the second outer casing peripheral wall 512 is located inside the second water inlet 424, thereby realizing the fixed installation of the filter part 500 on the water receiving tray 400.

[0174] In some embodiments of this application, reinforcing ring ribs 514 are provided between multiple connecting ribs 513 along the circumference of the outer shell, which further improves the overall structural strength of the outer shell without affecting water flow and filtration effect.

[0189] The outdoor bottom air inlet increases the air intake while avoiding the problem of sucking in impurities such as fallen leaves.

[0190] In some embodiments of this application, reference is made to Figure 2 The base plate, left and right side plates and top plate of the outdoor unit 200 are respectively provided with flanges on the side facing the outdoor front air outlet 211. The outdoor heat exchanger 230 is located near the outdoor front air outlet 211. Each flange is fixedly connected to the outdoor heat exchanger 230 by a connector (such as a screw).

[0191] The area enclosed by each flange forms the outdoor front air outlet 211, increasing the air outlet area and improving air outlet efficiency.

[0192] The outdoor heat exchanger 230 is exposed at the outdoor front outlet 211, which improves the heat dissipation effect of the outdoor heat exchanger 230.

[0193] In some embodiments of this application, a pad (not shown) or an adjustable bolt 260 is provided between the rear panel of the outdoor unit 200 and the outdoor side wall to improve the installation stability of the outdoor unit 200.

[0194] [Outdoor Unit - Internal Structure]

[0196] The front cavity is connected to the outdoor front air outlet 211, and the rear cavity is connected to the outdoor rear air inlet 213, the outdoor bottom air inlet, the outdoor side air inlet 212, and the outdoor top air inlet 214.

[0197] The outdoor heat exchanger 230 is located on the front side of the partition structure 240 and is situated in the front cavity.

[0198] The partition structure 240 is provided with an installation port (not shown), and an axial fan 250 is provided at the installation port. The axial fan 250 draws the air in the rear cavity to the front cavity, where it exchanges heat with the outdoor heat exchanger 230, and then is discharged directly from the outdoor front air outlet 211.

[0199] In some embodiments of this application, the compressor 220 is located in the space between the partition structure 240 and the rear panel and side panel of the outdoor unit 200, making full use of the internal space of the outdoor unit 200 and resulting in a compact structure.

[0224] [Saddle Bridge Structure - Outdoor Saddle Bridge Shell]

[0225] Regarding the specific structure of the outdoor saddle housing 320, in some embodiments of this application, refer to... Figures 11 to 13 The outdoor saddle axle housing 320 includes an outdoor saddle axle L-shaped base plate 321 and an outdoor saddle axle cover plate 322. The outdoor saddle axle cover plate 322 is located on the top of the transverse portion 3221 of the outdoor saddle axle L-shaped base plate, forming a second through cavity 323.

[0226] 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.

[0227] 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.

[0228] 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.

[0229] [Saddle Bridge Structure - Saddle Bridge Cover]

[0230] In some embodiments of this application, reference is made to Figure 3 and Figure 4 The saddle-type air conditioner also includes a saddle housing 330, which is fixedly connected to the outermost of the indoor saddle housing 310 and the outdoor saddle housing 320.

[0231] When the indoor saddle housing 310 and the outdoor saddle housing 320 move away from each other, the saddle cover 330 will block the inner one of the indoor saddle housing 310 and the outdoor saddle housing 320.

[0232] 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.

[0233] When the saddle bridge structure 300 is stretched, taking the outdoor saddle bridge shell 320 being fitted onto the outside of the indoor saddle bridge shell 310 as an example, refer to... Figure 3 andFigure 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.

[0234] 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.

[0235] 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.

[0236] 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.

[0237] 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.

[0238] 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.

[0239] [Saddle Bridge Structure - Electrical Box Installation]

[0240] In some embodiments of this application, reference is made to Figure 14 The interior of the saddle bridge structure 300 is a through cavity, and the electrical box 600 is located in the through cavity inside the saddle bridge structure 300.

[0241] The placement of the electrical box 600 makes full use of the internal space of the saddle bridge structure 300, making the overall structure more compact.

[0242] In some embodiments of this application, a gap is formed between the electrical box 600 and the side wall of the saddle structure 300 for the passage of heat exchange pipe 800 and drainage pipe 710.

[0243] The heat exchange pipeline 800 connecting the outdoor heat exchanger 230 and the indoor heat exchanger 120 extends along the inner cavity of the outdoor unit 200, the inner cavity of the saddle structure 300, and the inner cavity of the indoor unit 100.

[0244] The drain pump 700 is installed in the outdoor unit 200. The drain pump 700 is connected to the water tray 400 through the drain pipe 710. The drain pipe 710 extends along the inner cavity of the outdoor unit 200, the inner cavity of the saddle structure 300 and the inner cavity of the indoor unit 100, and extends to the water tray 400 of the indoor unit, specifically the inner water tank 422.

[0245] In some embodiments of this application, the electrical box 600 is disposed against one side of the through cavity, and a gap is formed between the electrical box 600 and the other side of the through cavity for the heat exchange pipe 800 and the drain pipe 710 of the air conditioner to run. The drain pipe 710 and the heat exchange pipe 800 extend from one side of the electrical box 600, making the internal structure of the saddle bridge structure 300 more regular and compact.

[0246] In this embodiment, the saddle bridge structure 300 not only connects the indoor unit 100 and the outdoor unit 00, but also serves to install the electrical box 600, run pipes, and route cables. It integrates multiple functions and has a more compact structure.

[0247] 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 800 and the drainage pipe 710 when the saddle bridge structure 300 extends or retracts, so as to avoid interference with the heat exchange pipe 800 and the drainage pipe 710 when the saddle bridge structure 300 extends or retracts.

[0248] 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.

[0249] Regarding the specific installation structure of the electrical box 600 inside the saddle bridge structure 300, some embodiments of this application refer to... Figure 27 The electrical box 600 has a first mounting part 621 on the top of one side, which is fixedly connected to the side wall forming the through cavity by a connector (such as a screw); the electrical box 600 has a second mounting part 622 on the bottom of the other side, which is fixedly connected to the bottom wall forming the through cavity by a connector (such as a screw).

[0250] The electrical box 600 can be fixedly installed inside the saddle bridge structure 300 through two connecting parts. The first mounting part 621 and the second mounting part 622 are staggered vertically to improve the installation stability of the electrical box 600.

[0251] [Vibration damping and waterproofing of the electrical box]

[0252] 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.

[0253] As a specific embodiment, refer to Figure 22 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.

[0254] 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.

[0255] In some embodiments of this application, reference is made to Figure 22 and Figure 27 The electrical box 600 has a flange 650 at the top opening. The flange 650 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.

[0256] [Internal structure of the electrical box]

[0257] In some embodiments of this application, reference is made to Figure 21 The internal space of the electrical box 600 includes a first internal space (not shown) and a second internal space (not shown) that are connected. The inclined wall 610 is one of the side walls that encloses the first internal space.

[0258] The first and second inner cavities are spatially divided, with no partition structure between them.

[0259] The first inner cavity contains a capacitor 661 and a transformer 662. The capacitor 661 is located near the inclined wall 610, and the transformer 662 is located on the opposite side wall to the inclined wall 610.

[0260] Due to the inclined wall 610, the first inner cavity space is an irregular space. The capacitor 661 and the transformer 62 are arranged opposite to each other in the first inner cavity space, making full use of the first inner cavity space.

[0261] The second inner cavity is equipped with a circuit board 663, which is laid flat in the second inner cavity to reduce the overall height of the electrical box 600 and realize the installation of the electrical box 600 inside the flat saddle bridge structure 300.

[0262] In some embodiments of this application, the side wall of the electrical box 600 is provided with a wiring port for wiring.

[0263] The wiring port is located on the top of the side wall of the electrical box 600, with an open top for easy wiring.

[0264] Furthermore, the opening at the top of the cable tray is smaller than the opening at the bottom, meaning that the cable tray has a top-tightening structure, which limits the cable passing through the cable tray and prevents the cable from coming out of the cable tray.

[0265] In some embodiments of this application, the wiring port includes a first wiring port 641 and a second wiring port 642 arranged at intervals. The first wiring port 641 is used for high-voltage lines, and the second wiring port 642 is used for low-voltage lines. The separation of high-voltage and low-voltage lines improves the safety and reliability of the electrical box.

[0266] [Wi-Fi module]

[0267] In some embodiments of this application, reference is made to Figure 21 and Figure 26 The outer wall of the electrical box 600 is equipped with a wifi module 900, which faces the indoor unit side.

[0283] The cable fixing part 680 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 680 and the bottom wall of the saddle bridge structure 300 define a cable routing hole, through which the power cable 670 passes.

[0284] In some embodiments of this application, the power cord 670 leading out from the electrical box 600 first extends horizontally along the bottom of the through cavity, and then extends vertically along the rear wall of the inner cavity of the indoor unit 100 to the wire hole 140.

[0285] The power cord 670 is routed close to the inner wall of the saddle bridge structure 300 and the indoor unit 100, without interfering with the installation and layout of other internal components (such as the drain pipe 710 and the heat exchange pipe 800).

[0286] 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 370 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 140.

[0287] Reference Figure 6 and Figure 24 The side of the saddle bridge cover 330 is provided with a clearance hole 334 that is directly opposite to the wire hole 140 so that the power cable 670 can pass through smoothly.
