[0038] The conventional wall-mounted indoor unit comprises a shell and an electrical box; the electrical box is installed in the shell. The circuit board of the indoor unit is located in the electrical box and connected with the side plate of the electrical box; the terminal row is arranged along the width direction of the electrical box, which leads to a larger size of the electrical box in the width direction. The plug-in connectors and the wire harness of the functional components of the conventional wall-mounted indoor unit are all arranged in the electrical box. With the increase of the number of the functional components, the volume of the electrical box is increased, and the wire harness of the box is disordered, which leads to difficulties in production and after-sales operation. The above two reasons lead to a larger size of the wall-mounted indoor unit and difficulties in production and after-sales operation. Therefore, under the condition that the functions of the indoor unit are increasing, how to control the size of the indoor unit is an urgent problem to be solved in the industry.

[0039] To solve the above problems, the utility model provides a wall-mounted indoor unit and air conditioner. Below combined Figures 1 to 5 The wall-mounted indoor unit and air conditioner are described in detail.

[0040] As Figures 1 to 5 The utility model discloses a wall-mounted indoor unit. The wall-mounted indoor unit comprises an electrical box 100, a circuit board 200, a mounting bracket 300 and functional components. The electrical box 100 has a mounting cavity. The circuit board 200 is located in the mounting cavity and connected with the electrical box 100. The mounting bracket 300 is located outside the mounting cavity and connected with the electrical box 100. The functional components are installed on the mounting bracket 300.

[0041] In this embodiment, by arranging the mounting bracket 300 outside the mounting cavity and connecting the mounting bracket 300 with the electrical box 100, the functional components can be integrated and installed on the mounting bracket 300, avoiding the installation of the functional components on the electrical box 100 and reducing the volume of the electrical box 100. By arranging the circuit board 200 in the mounting cavity of the electrical box 100 and connecting the circuit board 200 with the electrical box 100, the structure of the entire indoor unit is more compact. At the same time, the mounting bracket 300 is located outside the mounting cavity and connected with the electrical box 100, and the functional components are installed on the mounting bracket 300. Such a layout not only saves space but also improves the integration of the indoor unit, making the overall design more simple and efficient. This solves the problem that the size of the wall-mounted indoor unit is difficult to control with the increasing functions in the prior art. Since the functional components are installed on the mounting bracket 300, this design makes it easier to expand and upgrade when new functions are needed or existing functions are improved. This flexibility helps to meet the changing needs of users and market trends.

[0042] The conventional indoor unit has a function component installed in the electric appliance box 100. In order to install, maintain and adapt to different types of indoor units, a long wire harness is usually reserved, which leads to a messy wire harness in the electric appliance box 100 and difficulty in wire arrangement. In the embodiment, the function components are integrated and installed in the mounting bracket 300, the mounting bracket 300 is installed in the electric appliance box 100, and the mounting bracket 300 is relatively fixed with the electric appliance box 100. Therefore, the length of the wire harness between each function component and the circuit board 200 is fixed, thereby solving the problems of messy wire harness in the electric appliance box 100 and difficulty in wire arrangement. At the same time, each function component is installed in the mounting bracket 300. When the subsequent function components are disassembled and maintained, only the function component interface on the mounting bracket 300 needs to be disassembled and maintained, without the need to disassemble and maintain the circuit board 200, thereby simplifying the difficulty of after-sales maintenance.

[0043] In some embodiments, the wall-mounted indoor unit further comprises a housing and a cover; the housing comprises a shell and a front panel; the shell and the front panel enclose a containing cavity, the electric appliance box 100, the mounting bracket 300 and the function components are located in the containing cavity; the front panel is provided with an opening corresponding to the mounting bracket 300; the cover is installed on the front panel and used for covering the opening to seal the containing cavity. The housing and the cover provide a containing cavity for the electric appliance box 100, the mounting bracket 300 and the function components, and make the wall-mounted indoor unit beautiful.

[0044] It should be noted that the opening corresponding to the mounting bracket 300 means that the user can directly see the mounting bracket 300 through the opening by opening the cover, in other words, the opening exposes the mounting bracket 300.

[0045] Further, the opening corresponds to the second bracket 320. The second bracket 320 is located between the front panel and the front side plate of the electric appliance box 100.

[0046] In some embodiments, the mounting bracket 300 comprises a first bracket 310 and a second bracket 320; the first bracket 310 is located at the upper end of the electric appliance box 100 and connected with the electric appliance box 100; the second bracket 320 is formed at one end of the first bracket 310 and located at the front side of the electric appliance box 100; the function components are installed on the first bracket 310 or / and the second bracket 320. Specifically, the first bracket 310 is located between the upper side plate of the electric appliance box 100 and the top plate of the housing, and the first bracket 310 is installed on the electric appliance box 100; the second bracket 320 is located between the front side plate of the electric appliance box 100 and the front panel, and the upper end of the second bracket 320 is connected with one end of the first bracket 310 facing the front side plate.

[0047] In this embodiment, by reasonably arranging the first support 310 and the second support 320, the space of the indoor unit can be fully utilized. This design not only saves space, but also makes the appearance of the entire indoor unit more neat and beautiful. At the same time, it is also convenient for users to operate and maintain during installation and use. By arranging the first support 310 at the upper end of the electrical box 100, the functional components can be installed on the first support 310, realizing the utilization of the space above the electrical box 100; by arranging the second support 320 at the front side of the electrical box 100, the functional components can be installed on the first support 310, realizing the utilization of the space in front of the electrical box 100. Since the functional components can be installed on the first support 310 or / and the second support 320, this design provides great flexibility. According to actual needs, the position and number of functional components can be flexibly adjusted to meet different application scenarios and user needs. This flexibility makes the indoor unit have stronger adaptability and expandability. The design of the first support 310 and the second support 320 makes the installation process simpler and faster. At the same time, since the functional components can be conveniently installed on the supports, it is also convenient for subsequent maintenance and replacement work. This design reduces the difficulty and cost of installation and maintenance, and improves the user experience.

[0048] Specifically, the second support 320 corresponds to the opening. In other words, the second support 320 is located between the cover and the front side plate of the electrical box.

[0049] In some embodiments, the functional components include at least one of a terminal row 410, an electromagnetic switch, a Wi-Fi module, a stepping motor, a temperature sensor, a humidity sensor, or a wire clamp 420.

[0050] Specifically, the first support 310 has an electromagnetic switch interface, a Wi-Fi module interface, a stepping motor interface, a temperature sensor interface, and a humidity sensor interface. The electromagnetic switch interface, the Wi-Fi module interface, and the stepping motor interface are located on the upper side of the first support 310, and the temperature sensor interface and the humidity sensor interface are arranged on the left side or / and the right side of the first support 310. In this way, the space utilization of the first support 310 can be improved, which is beneficial to the miniaturization design of the indoor unit.

[0051] Further, the functional components include the terminal row 410. The mounting support 300 has a terminal row 410 interface, and the terminal row 410 interface is detachably connected with the terminal row 410. This facilitates the disassembly and maintenance of the terminal row 410.

[0052] For example, the terminal row 410 is detachably installed on the first support 310, and the projection of the terminal row 410 on the horizontal plane at least partially overlaps with the projection of the circuit board 200. In other words, under the top-down view, the projection of the terminal row 410 partially overlaps with the projection of the circuit board 200, as shown in Figure 4As shown, rather than being arranged apart from each other. When the terminal block 410 of the conventional indoor unit is arranged along the width direction of the electrical box, the terminal block 410 and the circuit board 200 are arranged apart from each other in the top view. In this way, the size of the electrical box 100 in the width direction can be further reduced, thereby reducing the size of the indoor unit in the width direction.

[0053] Specifically, the second support 320 has a terminal block 410 interface, and the terminal block 410 is detachably connected to the terminal block 410 interface.

[0054] For example, the terminal block 410 is detachably mounted on the second support 320, and the terminal block 410 at least partially overlaps the front projection of the circuit board 200. In other words, in the front view, the terminal block 410 partially overlaps the projection of the circuit board 200, as shown. Figure 5 As shown, rather than being arranged apart from each other. When the terminal block 410 of the conventional indoor unit is arranged along the width direction of the electrical box, the terminal block 410 and the circuit board 200 are arranged apart from each other in the front view. In this way, the size of the electrical box 100 in the width direction can be further reduced, thereby reducing the size of the indoor unit in the front projection. In addition, mounting the terminal block 410 on the second support 320, which is located on the front side of the electrical box 100, that is, on the side of the electrical box 100 facing the front panel of the housing, can reduce the length of the wiring harness of the indoor unit passing through the entire machine, facilitating installation and wiring.

[0055] It should be noted that the front projection size of the indoor unit refers to the projection size of the indoor unit in the front view.

[0056] Specifically, the second support 320 has a terminal block 410 interface, and the terminal block 410 is detachably connected to the terminal block 410 interface.

[0057] In some embodiments, the wall-mounted indoor unit further comprises a fireproof cover 500; the fireproof cover 500 is mounted on the second support 320 to form an installation space, an inlet port and an outlet port with the second support 320, and the terminal block 410 is located in the installation space; the inlet port and the outlet port are in communication with the installation space. In this way, the installation space formed by the fireproof cover 500 and the second support 320 provides a good working environment for the terminal block 410 and other key components, thereby protecting the terminal block 410 and other components. The fireproof cover 500 can prevent dust, dirt and other impurities from entering the installation space, thereby keeping the terminal block 410 and other components clean. This helps to reduce the problem of circuit short circuit or component damage caused by dust accumulation.

[0058] Further, the wall-mounted indoor unit further comprises a fireproof protective shell 600; the fireproof protective shell is located in the mounting space and connected with the mounting support 300; and the terminal strip 410 is detachably mounted in the fireproof protective shell 600. In this way, the fireproof protective shell 600 and the fireproof cover 500 wrap the terminal strip 410, further improving the protection of the terminal strip 410.

[0059] Specifically, the fireproof protective shell 600 is a fireproof iron sheet; the fireproof iron sheet is laid on the interface of the terminal strip 410, and the terminal strip 410 is mounted on the fireproof iron sheet.

[0060] In some embodiments, the functional components further comprise a wire clamp 420; along the wire direction, the wire clamp 420 is located downstream of the terminal strip 410 and is detachably connected with the mounting support 300. Specifically, the terminal strip 410 is mounted on the second support 320, and the wire clamp 420 is located at the lower end of the terminal strip 410. The wire clamp 420 is used to fix and arrange the wire bundle, ensuring that the cables are neatly arranged and avoiding confusion and entanglement. This helps to improve the internal layout of the indoor unit, making it look more tidy and orderly. By placing the wire clamp 420 downstream of the terminal strip 410, it can ensure that the cables are properly managed after being connected to the terminal strip 410, preventing connection problems caused by loose or misaligned cables. The fixing effect of the wire clamp 420 can reduce the vibration and movement of the cables, thereby reducing the risk of circuit failure caused by cable wear or breakage. The detachable connection makes the wire clamp 420 easy to install and remove, facilitating the inspection, repair or replacement of the cables when needed, further improving the safety and reliability of the indoor unit.
