The following description is provided to enable any person skilled in the art to make and use this application. In the following description, details are set forth for the purpose of explanation. It should be understood that those of ordinary skill in the art can recognize that this application can be implemented without these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of this application with unnecessary details. Therefore, this application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in this application.

[0027] As Figures 1 to 3 shown, on the one hand, an embodiment of this application provides an electrical appliance box 1, which includes a shielding box 10 and an insulating box 20. Devices such as a WiFi module 3 and a room temperature sensor 4 can be centrally arranged in the electrical appliance box 1, reducing the material cost.

[0028] The shielding box 10 has an electromagnetic shielding function. On the one hand, it can shield electromagnetic signals from outside the shielding box 10 and prevent electromagnetic signals from outside the shielding box 10 from interfering with the electronic devices inside the shielding box 10. On the other hand, it can shield electromagnetic signals emitted by the electronic devices inside the shielding box 10 and prevent electromagnetic signals from the electronic devices inside the shielding box 10 from interfering with devices outside the shielding box 10. The shielding box 10 can be made of a conductive material, and the conductive material includes types such as metal materials; in some embodiments, the shielding box 10 can be a sheet metal part.

[0029] The insulating box 20 has a first box body part 21 and a second box body part 22 which are connected to each other and are made of insulating materials such as plastic materials. The first box body part 21 is embedded in the shielding box 10 and is used for installing the electronic control board 2 and the terminal block 5. In this way, electronic devices such as the electronic control board 2 and the terminal block 5 arranged in the first box body part 21 can be protected by the electromagnetic shielding of the shielding box 10. The second box body part 22 is located outside the shielding box 10 and is used for installing at least one of the WiFi module 3 and the room temperature sensor 4. In this way, the WiFi module 3 arranged in the second box body part 22 can be protected from the electromagnetic shielding of the shielding box 10 and thus can communicate wirelessly with devices in the external environment without hindrance, while the room temperature sensor 4 can be in contact with the indoor air environment and thus measure the indoor environmental temperature.

[0030] Compared with the related art, in the electrical appliance box 1 provided by the embodiment of the present application, by setting the insulating box 20 to have a first box body part 21 and a second box body part 22, the first box body part 21 is embedded in the shielding box 10 and can be protected by the electromagnetic shielding of the shielding box 10, so it is suitable for installing the electronic control board 2 and the terminal block 5, while the second box body part 22 is located outside the shielding box 10 and can be protected from the electromagnetic shielding and the airflow blocking effect of the shielding box 10, so it is suitable for installing the WiFi module 3 and the room temperature sensor 4. In this way, devices such as the WiFi module 3 and the room temperature sensor 4 can be centrally arranged in the electrical appliance box 1, and there is no need to additionally set up an installation structure in the air conditioner indoor unit, which can reduce the overall machine material cost.

[0031] The forming method of the first box body part 21 and the second box body part 22 can be determined according to actual needs, and forming methods such as integral injection molding can be adopted. The embodiment of the present application does not limit this.

[0032] In some embodiments, the first box body part 21 may be provided with a first installation cavity 211 and a first installation surface 212. The first installation cavity 211 is used for installing the electronic control board 2, that is, the electronic control board 2 can be embedded in the first installation cavity 211. The first installation surface 212 is formed on the outer surface of the first box body part 21 and is used for installing the terminal block 5. The first installation surface 212 is inclined upward at an angle with the horizontal direction, so that the operation space above the first installation surface 212 is larger, which is convenient for the operator to perform line installation and disassembly operations on the terminal block 5 located on the first installation surface 212.

[0033] In some examples, the shielding box 10 may include a shielding box body 11, a shielding box cover 12, and a shielding door cover 13. The shielding box body 11 and the shielding box cover 12 are detachably enclosed to form a receiving cavity that is open in the horizontal direction, and the shielding door cover 13 is detachably covered on the opening of the receiving cavity. The first box body portion 21 is embedded in the receiving cavity, and the shielding box cover 12 covers the opening side of the first installation cavity 211. The first installation cavity 211 can be closed by installing the shielding box cover 12 or exposed by removing the shielding box cover 12. The first installation surface 212 is arranged facing the shielding door cover 13. The first installation surface 212 can be shielded by installing the shielding door cover 13 or exposed by removing the shielding door cover 13. Since the wiring terminal 5 is arranged on the first installation surface 212, the wiring terminal 5 is arranged in the space area above the first installation surface 212 in the receiving cavity, and this space area is the wiring operation space.

[0034] Here, the first installation surface 212 extends in an inclined downward direction and approaches the shielding door cover 13, so that one end of the wiring operation space close to the opening of the receiving cavity has a larger cross-section, while the end far from the opening of the receiving cavity has a smaller cross-section. Furthermore, the wiring operation space presents a tapered structure with a large mouth and a small bottom. Since the space at one end of the wiring operation space close to the opening is large, it is easy for the operator to perform line installation and disassembly operations, thereby improving the convenience of line installation and disassembly operations and reducing the operation difficulty.

[0035] Exemplarily, the shielding box body 11, the shielding box cover 12, and the shielding door cover 13 can be respectively snap-fixed to the first box body portion 21 to enclose and wrap the first box body portion 21. By adopting the snap-fixing method, the shielding box body 11, the shielding box cover 12, the shielding door cover 13 and the first box body portion 21 can be quickly connected or disassembled, improving the installation and disassembly efficiency. And by respectively fixing the shielding box body 11, the shielding box cover 12 and the shielding door cover 13 to the first box body portion 21, the shielding box 10 and the first box body portion 21 can be connected more closely, increasing the reliability of the connection structure.

[0036] Exemplarily, limiting buckle edges 213 can be respectively provided at the opposite side edge portions of the first installation surface 212, and the shielding door cover 13 is buckled between the limiting buckle edges 213. Here, the limiting buckle edges 213 can be provided on the first installation surface 212 protruding along the orientation of the first installation surface 212. The number of the limiting buckle edges 213 can be determined according to actual needs, and can be, for example, two or more. The embodiments of the present application do not limit this. In this way, a plurality of limiting buckle edges 213 located at the opposite side edge portions of the first installation surface 212 can clamp and fix the shielding door cover 13 therein, and the limiting buckle edges 213 and the shielding door cover 13 are snap-fixed to achieve the purpose of quick installation and disassembly.

[0037] Exemplarily, the electrical appliance box 1 may further include a conductive junction box 30. The conductive junction box 30 is disposed on the first mounting surface 212 and is electrically connected to the shielding door cover 13. A second mounting surface 31 for mounting the terminal block 5 is provided in the conductive junction box 30, and the second mounting surface 31 is arranged parallel to the first mounting surface 212. In this way, the terminal block 5 can be mounted by using the conductive junction box 30, and the ground terminal in the terminal block 5 can be electrically connected to the conductive junction box 30, and the grounding is achieved by using the electrical connection between the conductive junction box 30 and the shielding door cover 13, without the need to additionally provide a ground wire, thereby saving connection wires and simplifying the line connection structure. The conductive junction box 30 can be made of a conductive material such as a metal material, etc., and the embodiments of the present application do not limit this; exemplarily, the conductive junction box 30 can be made of a metal material through a sheet metal process.

[0038] Exemplarily, the shielding door cover 13 may include a shielding cover body 131 and an insulating cover body 132. The shielding cover body 131 can be made of a conductive material such as a metal material, etc., and thus can be electrically connected to the above-mentioned conductive junction box 30, while the insulating cover body 132 can be made of an insulating material such as a plastic material. The insulating cover body 132 is snap-fixed to the first box body portion 21, and the shielding cover body 131 is disposed on the side of the insulating cover body 132 facing the first mounting surface 212. In this way, the operator can perform the installation and disassembly operations on the shielding door cover 13 by contacting the insulating cover body 132, without contacting the shielding cover body 131 to avoid the risk of electric shock and injury.

[0039] In some examples, the first installation cavity 211 may have a first bottom wall 2111 and a first side wall 2112 provided around the edge of the first bottom wall. The first installation cavity 211 is formed by enclosing the first bottom wall 2111 and the first side wall 2112. When the electronic control board 2 is installed in the first installation cavity 211, the distance between the first side wall 2112 and the edge of the electronic control board 2 is less than or equal to 3.5 mm. On the one hand, the first side wall 2112 can enclose and shield the electronic control board 2 to prevent small animals or other impurities from entering the first installation cavity 211 and causing damage to the electronic control board 2; on the other hand, by limiting the distance between the first side wall 2112 and the edge of the electronic control board 2 as above, it can be ensured that the operator can easily install or disassemble the electronic control board 2, and the space between the first side wall 2112 and the electronic control board 2 is small, further preventing small animals or other impurities from entering the first installation cavity 211 and reducing the risk of damage to the electronic control board 2.

[0040] In some embodiments, a plurality of wire passing openings 23 may be provided on the insulating box 20. The plurality of wire passing openings 23 are respectively disposed on different sides of the insulating box 20 and extend in different directions; for example, wire passing openings 23 may be respectively provided on the front side, rear side, and left side of the insulating box 20. In this way, electronic devices located in different regions within the insulating box 20 can select a wire passing opening 23 nearby for wire routing, making the wire distribution more concise and effectively shortening the wire routing length. In some examples, a plurality of wire passing openings 23 are formed by detachably enclosing the region of the second box body portion 22 close to the first box body portion 21 and the shielding box 10; in this way, the formed wire passing holes of the second box body portion 22 and the shielding box 10 can guide and restrict the wire routing, further increasing the rationality of the wire arrangement. Exemplarily, a wire passing opening 23 may be provided on the first side wall 2112.

[0041] In some embodiments, the edge portion of the shielding box 10 may have a flanging structure. In other words, the edge portion of the shielding box 10 is bent to form a flanging structure in a folded state, making the portion of the shielding box 10 in contact with the insulating box 20 or the wire relatively smooth, avoiding scratching and abrasion of the insulating box 20 or the wire.

[0042] In some embodiments, a second installation cavity 221 may be provided on the second box body portion 22, and the second installation cavity 221 is used for installing the WiFi module 3 and the room temperature sensor 4. Here, the second installation cavity 221 may be opened on one side of the second box body portion 22. In some examples, the WiFi module 3 and the room temperature sensor 4 may be respectively snapped into the second installation cavity 221.

[0043] On the other hand, an embodiment of the present application provides an indoor unit of an air conditioner, and the indoor unit of the air conditioner includes the electrical box 1 provided in any of the above embodiments. The type of the indoor unit of the air conditioner can be determined according to actual needs, and the indoor unit structure type of a split-structured air conditioner such as a wall-mounted air conditioner or a cabinet air conditioner can be adopted, and the embodiments of the present application do not limit this.

[0044] Here, the indoor unit of the air conditioner may include an electronic control board 2, a WiFi module 3, a room temperature sensor 4, and a terminal block 5. The electronic control board 2 may be disposed in the first installation cavity 211 on the first box body portion 21 and within the shielding box 10, the WiFi module 3 and the room temperature sensor 4 may be disposed in the second installation cavity on the second box body portion 22 and outside the shielding box, and the terminal block 5 may be disposed on the conductive terminal box 30 installed on the first box body portion 21 and within the shielding box 10.

[0045] The above has introduced in detail the electrical box and the indoor unit of the air conditioner provided by the embodiments of the present application.
