[0036] Please see Figures 1-3 The indoor air conditioner unit 100 of this application includes a housing 10 and accessories 20. The housing 10 includes a top plate 11, a front sealing plate 12 and a side plate 13. The front sealing plate 12 is located on the air outlet side of the indoor air conditioner unit 100 and is fixedly connected to the top plate 11. The side plate 13 is detachably connected to the top plate 11 and the front sealing plate 12 respectively. Accessories 20 are disposed inside the housing 10 and are disposed corresponding to the side plate 13.

[0037] In the above-mentioned air conditioner indoor unit 100, the side panel 13 is detachably connected to the top panel 11 and the front sealing plate 12 respectively, so that when maintaining the accessories 20 of the air conditioner, the side panel 13 can be removed separately without removing the front sealing plate 12, which facilitates the maintenance of the air conditioner indoor unit 100.

[0038] Specifically, the housing 10 can be a cubic structure, and the housing 10 can accommodate other components of the air conditioner indoor unit 100. The housing 10 can form an airflow channel, through which airflow can flow into the room.

[0039] The top plate 11 of the housing 10 is the upward-facing panel when the indoor unit 100 is in normal use. The side plate 13 is located on one side of the housing 10. The housing 10 may also have front and rear plates, which are panels arranged along the airflow direction of the housing 10. Generally, the panel downstream in the airflow direction is the front plate, and the panel upstream in the airflow direction is the rear plate. The front sealing plate 12 is one of the front plates of the indoor unit 100.

[0040] The side panel 13 can be connected to the top panel 11 and the front sealing plate 12 respectively by screws or other means, so that the side panel 13 can be disassembled. The accessories 20 are the removable and replaceable parts inside the air conditioner indoor unit 100, including but not limited to sensors, electronic valves, connectors, etc.

[0041] Please see Figure 3 In some embodiments, the top plate 11 includes a flat plate portion 111 and a first bent portion 112 connected to the flat plate portion 111. The first bent portion 112 is stacked with a side plate 13, and the side plate 13 presses against and covers the outside of the first bent portion 112. The side plate 13 is detachably connected to the first bent portion 112.

[0042] Thus, the first bend 112 allows the top plate 11 and the side plate 13 to be connected, improving the stability of the side plate 13 installation. In addition, the side plate 13 is located outside the first bend 112, so that the side plate 13 can be moved and removed along the thickness direction of the side plate 13 during disassembly, and the first bend 112 will not interfere with the side plate 13, thereby improving the disassembly efficiency of the side plate 13.

[0043] Specifically, the flat plate portion 111 is located on the top side of the housing 10, and the first bent portion 112 is bent relative to the flat plate portion 111. The first bent portion 112 and the flat plate portion 111 can be arranged perpendicularly. The overall area of ​​the first bent portion 112 is smaller than the overall area of ​​the flat plate portion 111. The flat plate portion 111 and the first bent portion 112 can be made of the same sheet material and formed by a bending process.

[0044] Please see Figure 2 and Figure 4 In some embodiments, the top plate 11 includes a flat plate portion 111 and a second bent portion 113 connected to the flat plate portion 111. The second bent portion 113 is stacked with the front sealing plate 12, and the front sealing plate 12 is fixedly connected to the second bent portion 113.

[0045] Thus, the second bend 113 can provide an installation position for the front sealing plate 12, allowing the side plate 13 to be connected to the top plate 11, thereby improving the stability of the installation of the front sealing plate 12.

[0046] Specifically, the second bent portion 113 is bent relative to the flat portion 111. The first bent portion 112 can be perpendicular to the flat portion 111. The overall area of ​​the first bent portion 112 is smaller than the overall area of ​​the flat portion 111. The flat portion 111 and the first bent portion 112 can be made of the same sheet material and formed by a bending process.

[0047] Please see Figure 2 and Figure 4 In some embodiments, the second bend 113 is located outside the front sealing plate 12, and the end of the front sealing plate 12 abuts against the flat plate 111. In this way, the end of the front sealing plate 12 can support the top plate 11, which helps to improve the stability of the top plate 11 and can improve the structural strength of the entire housing 10.

[0048] In the above embodiments, "outer side" refers to the side away from the inner center of the housing 10, and "inner side" refers to the side facing the inner center of the housing 10.

[0049] Please see Figure 1 and Figure 2 In some embodiments, the side panel 13 is provided with an inspection window 131, and the housing 10 includes an inspection plate 14 that covers the inspection window 131. The inspection plate 14 is detachably connected to the side panel 13. Since the volume of the inspection plate 14 is generally smaller than that of the side panel 13, the internal structure of the housing 10 can be observed after opening the inspection window 131 through the inspection plate 14. This facilitates observation of the status of the components 20 through the inspection window 131. If the components 20 require maintenance, the side panel 13 can be further disassembled, thereby improving the stability of maintenance of the indoor air conditioning unit 100. Furthermore, the inspection plate 14 covering the inspection window 131 reduces the entry of foreign objects into the housing 10, improving the operational stability of the indoor air conditioning unit 100.

[0050] Please see Figures 3-4 In some embodiments, a handle 30 is fixedly provided on the inspection plate 14, and the inspection plate 14 and the handle 30 are installed together by passing through the first fastener 40 in sequence through the handle 30, the inspection plate 14, the side plate 13 and the top plate 11.

[0051] Thus, the handle 30 makes it easier to move the indoor unit 100 of the air conditioner. Furthermore, the first fastener 40 is sequentially inserted through the handle 30, the inspection plate 14, the side plate 13 and the top plate 11, so that the installation position of the handle 30 has at least a three-layer plate structure, which improves the reliability of the handle 30 during use.

[0052] Specifically, the handle 30 may include a grip portion 31, a connecting portion 32, and a mounting portion 33. The connecting portion 32 connects the grip portion 31 and the mounting portion 33, and the mounting portion 33 is fitted to the access plate 14. The first fastener 40 may be, for example, a screw.

[0053] In some embodiments, the handle 30 is fixedly connected to the access plate 14 by a second fastener 41. In this way, the access plate 14 can be held by the handle 30 during disassembly, making the access plate 14 easier to disassemble.

[0054] Specifically, the second fastener 40 can be a screw or rivet, which secures the handle 30 to the access plate 14. During the disassembly of the access plate 14, the handle 30 remains fixed to the access plate 14, which not only facilitates the disassembly of the access plate 14 but also reduces the risk of the handle 30 being lost if it becomes detached from the access plate 14.

[0055] Of course, in other embodiments, the handle 30 can be fixedly connected to the inspection plate 14 by welding or other means.

[0056] Please see Figure 1 In some embodiments, the indoor unit 100 of the air conditioner includes a heat exchanger 50 and a pipe 60 connected to the heat exchanger 50, with the pipe 60 passing through a side panel 13. This allows the indoor unit 100 to be easily connected to the outside environment. The fittings 20 are generally located on the side where the heat exchanger 50 connects to the pipe 60, allowing for maintenance of the fittings 20 after the side panel 13 is removed.

[0057] Specifically, pipe 60 can be a refrigerant pipe, which can be connected to the outdoor unit of the air conditioner, so that the indoor unit 100 and the outdoor unit of the air conditioner can flow refrigerant, thereby achieving the effect of cooling or heating.

[0058] Please see Figure 1 , Figure 4 and Figure 5 In some embodiments, the indoor unit 100 of the air conditioner includes a mounting bracket 70, on which the heat exchanger 50 is mounted. A seal 71 is provided between the mounting bracket 70 and the front sealing plate 12. The fitting 20 is located within the space enclosed by the top plate 11, the mounting bracket 70, and the side plate 13. Thus, the mounting bracket 70 can improve the stability of the heat exchanger 50 installation, and the seal 71 can reduce the seal of the housing 10, thereby improving the heat exchange efficiency between the heat exchanger 50 and the surrounding gas.

[0059] Specifically, the mounting part 70 can be a plate-like part, and the mounting part 70 can be bent. One part of the mounting part 70 is used to install the heat exchanger 50, and the other part is used to form a space with the top plate 11 and the side plate 13.

[0060] Please see Figure 1 , Figure 5 and Figure 6 In some embodiments, the front sealing plate 12 is provided with a lifting lug 80, which includes a connecting piece 81 and a lifting piece 82 connected to the connecting piece 81. The connecting piece 81 is fixedly connected to the front sealing plate 12, and the lifting piece 82 is provided with a lifting hole 821 that penetrates the edge of the lifting piece 821 away from the front sealing plate 12. In this way, the indoor unit 100 of the air conditioner can be lifted by the lifting lug 80, making the installation of the indoor unit 100 of the air conditioner more convenient.

[0061] Please see Figure 7 In some embodiments, there are two housings 10, which are detachably connected and interconnected. The indoor unit 100 of the air conditioner also includes a fan 90, which is disposed in one of the housings 10, and the heat exchanger 50 is disposed in the other housing 10.

[0062] In this way, the indoor unit 100 of the air conditioner is divided into two parts, which makes it easier to move the indoor unit 100 and thus facilitates the transportation and installation of the indoor unit 100 of the air conditioner.

[0063] Specifically, the two housings 10 can be fixed together by screws or other means. The structures of the two housings 10 can be different. For example, the housing 10 that houses the heat exchanger 50 may be equipped with a maintenance panel 14, while the housing 10 that houses the fan 90 may not have a maintenance window 131 on the side panel 13.

[0064] The fan 90 can be a centrifugal fan or an axial fan. The heat exchanger 50 can be arranged at an angle. This angled arrangement increases or decreases the height space occupied by the heat exchanger 50 after installation, resulting in a lower overall height of the indoor unit 100. This facilitates miniaturization of the indoor unit 100, reducing its weight and making installation and handling easier. The angled arrangement of the heat exchanger 50 means that the entire surface of the air inlet and outlet sides of the heat exchanger 50 is inclined relative to the horizontal plane; in other words, the entire surface of the air inlet and outlet sides of the heat exchanger 50 is set at an angle relative to the horizontal plane.

[0065] Please see Figure 8 The air conditioning system 1000 of this application includes an indoor unit 100 and an outdoor unit 200 as described in any of the above embodiments. The outdoor unit 200 and the indoor unit 100 are connected by a connecting pipe. Specifically, the outdoor unit 200 may include components such as a compressor. During operation, the compressor can perform work on the refrigerant, allowing the refrigerant to exchange heat with the heat exchanger 50, thereby regulating the indoor temperature.

[0066] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0067] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
