[0002] Currently, most window air conditioners on the market are square in shape and are integrated air conditioners, consisting of a chassis, cover, panel, air duct, indoor fan, outdoor fan, motor, compressor, condenser, evaporator, etc. After installation, the height of the sunlight blocking is approximately the total height of the window air conditioner, and customers cannot enjoy sufficient sunlight; since the outdoor part and the indoor part of the window air conditioner are an integral whole, the noise generated by the outdoor part will also be transmitted to the indoor room, resulting in very loud noise, affecting the customer's comfort, and it is not suitable for customers who are sensitive to noise.

[0003] To address this problem, the saddle-type air conditioner emerged. It consists of an indoor section and an outdoor section, separating the indoor and outdoor areas, effectively reducing indoor noise. The indoor and outdoor sections are connected by a saddle bridge. The indoor section primarily includes the panel, housing, chassis, evaporator, cross-flow fan, motor, air duct, and electronic control components. The outdoor section primarily includes the housing, chassis, compressor, condenser, piping, motor, motor bracket, and axial fan.

[0076] Saddle type air conditioner]

[0077] This embodiment discloses a saddle-type air conditioner, referring to Figure 1 , which 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.

[0078] The saddle-type air conditioner has an N-shaped structure. The indoor unit 100 and the outdoor unit 200 are respectively arranged at both ends of the saddle bridge structure 300 and on the same side of the saddle bridge structure 300 , extending toward the bottom of the saddle bridge structure 300 .

[0079] When the saddle-type air conditioner is installed on a window, the saddle bridge structure 300 is directly seated on the window, the indoor unit 100 is located on the indoor side, and the outdoor unit 200 is located on the outdoor side.

[0080] 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 existing integrated window units blocking sunlight after installation.

[0081] The indoor unit 100 is separated from the outdoor unit 200 by the saddle bridge structure 300, which helps to prevent the noise of the outdoor unit 200 from being transmitted to the indoor side, thereby improving user comfort.

[0082] The indoor unit 100 mainly includes a casing, an indoor heat exchanger, a water receiving pan, a cross-flow fan, an air duct and other components.

[0083] The outdoor unit 200 mainly includes a casing, an outdoor heat exchanger, an axial flow fan, a compressor and other components.

[0084] Power Cord Routing]

[0085] In some embodiments of the present application, an electrical box 600 and a wire winding portion 500 are provided in the inner cavity of the saddle bridge structure 300 .

[0086] The winding part 500 is used to wind the power line 400 drawn from the electrical box 600. The structural diagram of the winding part 500 is shown in FIG. Figure 18 and Figure 19 .

[0087] The power cord 400 is led out from the electrical box 600, and a section of the power cord is wound on the winding part 500. The power cord 400 then extends from the winding part 500 to the side of the indoor unit 100, and then extends from the indoor unit 100 to connect to the indoor power socket.

[0088] The routing structure of the power line 400 fully utilizes the internal space of the saddle bridge structure 300, making the routing of the power line simple and convenient.

[0089] Through the winding part 500, the power cord 400 can be configured to have a certain length to adapt to power sockets in different positions in the room. If the power socket is far away from the window machine, the power cord 400 can be pulled longer; if the power socket is close to the window machine, the power cord 400 can be pulled shorter, which greatly improves the user's convenience. Moreover, under the action of the winding part 500, the power cord 400 will not appear in a drooping state.

[0090] In some embodiments of this application, refer to Figure 16 and Figure 17 The indoor unit 100 has a wire hole 120 on the side of its housing, located near the rear panel of the indoor unit 100. The power cord 400 extending from the electrical box 600 first extends horizontally along the inner cavity of the saddle bridge structure 300 to the winding portion 500, where it is wound. It then extends downward along the rear wall of the inner cavity of the indoor unit 100 to the wire hole 120 for exit.

[0091] The wire hole 120 is located at the rear side of the indoor unit 100. The power cord 400 led out from the electrical box 600 passes through the inner cavity of the indoor unit 100 at the shortest distance, reducing the internal wiring length and making the interior of the air conditioner more regular and compact. At the same time, after the power cord 400 is led out from the rear side of the indoor unit 100, it can continue to extend along the indoor wall to connect to the power plug, which is also convenient for indoor wiring and more beautiful.

[0092] In some embodiments of the present application, the power cord 400 located between the electrical box 600 and the winding part 500 is fixed in the inner cavity of the saddle bridge structure 300 through a positioning structure. In this way, when the power cord is pulled, the section of the power cord between the electrical box 600 and the winding part 500 will not be pulled, thereby improving the electrical connection reliability between the power cord 400 and the electrical box 600.

[0093] The positioning structure can be a common binding strap, a cable tie, a cable clamp, etc.

[0094] In some embodiments of this application, refer to Figure 18 and Figure 19 The winding portion 500 includes a frame, a mounting shaft 510 is provided in the frame, a rotating drum 520 is provided outside the mounting shaft 510, an elastic member 560 is provided between the mounting shaft 510 and the rotating drum 520, and the power cord 400 is wound around the rotating drum 520.

[0095] Pulling the power cord 400 drives the drum 520 to rotate, and the elastic member 560 contracts under the force, and the power cord 400 is stretched to connect with the power socket. Then the power cord 400 is released, and the elastic member 560 rebounds, driving the drum 520 to rotate in the opposite direction. The excess length of the power cord 400 is wound around the drum 520 again.

[0096] The elastic member 560 can be a spring, which is sleeved on the mounting shaft 510. One end of the spring is fixedly connected to the mounting shaft 510, and the other end of the spring is fixedly connected to the rotating drum 520. The resetting force of the spring realizes the resetting rotation of the rotating drum 520, thereby realizing the winding and rewinding of the power cord 400.

[0097] In some embodiments of the present application, the cord winding portion 500 can be manual, and the frame includes a top plate 530, a bottom plate 540 and a connecting bar 550. A plurality of spaced connecting bars 550 are provided between the top plate 530 and the bottom plate 540. The upper end of the mounting shaft 510 is rotatably connected to the top plate 530, and the lower end of the mounting shaft 510 is rotatably connected to the bottom plate 540. The power cord 400 extends from the gap between two adjacent connecting bars 550.

[0098] The frame is a non-enclosed structure, which is convenient for wiring, assembly, disassembly and maintenance of the power cord 400.

[0099] In some embodiments of the present application, the winding portion 500 may be electric, with a motor provided in the frame, and a power output end of the motor connected to the mounting shaft 510 to drive the mounting shaft 510 to rotate synchronously.

[0100] Pulling the power cord 400 drives the rotating drum 520 to rotate, and the elastic member 560 contracts under force, and the power cord 400 is stretched until it is connected to the power socket. Then, the power cord 400 is released, the motor starts, and drives the mounting shaft 510 to rotate in the opposite direction. The elastic member 560 rebounds, and drives the rotating drum 520 to rotate in the opposite direction. The excess length of the power cord 400 is wound around the rotating drum 520 again.

[0101] The process of the power cord 400 being retracted and wound is electric, and the reliability of the retraction of the power cord 400 is improved through the dual functions of the motor and the elastic member 560.

[0102] The motor can be fixed on the top plate 530 , the upper end of the mounting shaft 510 is connected to the motor, and the lower end of the mounting shaft 510 is rotatably connected to the bottom plate 540 .

[0103] The power line 400 is routed close to the inner wall of the saddle bridge structure 300 and the indoor unit 100, and does not interfere with the installation and layout of other internal components (such as the drainage pipe 710 and the heat exchange pipe 800).

[0104] Saddle bridge structure]

[0105] In some embodiments of the present application, the saddle bridge structure 300 is retractable, and the length of the saddle bridge structure 300 can be adjusted to accommodate walls of different thicknesses.
