[0037] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-9 The electric control box 100 according to an embodiment of the present invention is described. The electric control box 100 includes: a first box body 10, a second box body 20, a cover 30, an electric control board 40, and a handle 50.

[0038] Specifically, such as Figures 1-3As shown, the first box 10 is open on one side along the first direction A, the second box 20 is located on the same side of the first box 10 along the first direction A, and the cover 30 is detachably connected to one end of the first box 10 and the second box 20 along the second direction B perpendicular to the first direction A. The cover 30, the first box 10 and the second box 20 together define a receiving cavity 60. The electronic control board 40 is located in the receiving cavity 60 and is arranged along the second direction B. The handle 50 is located on the cover 30. The end face of the handle 50 along the second direction B away from the center of the receiving cavity 60 protrudes from the surface of the cover 30 along the second direction B away from the center of the receiving cavity 60. The end of the handle 50 along the second direction B near the center of the receiving cavity 60 extends into the receiving cavity 60 and abuts against the electronic control board 40.

[0039] The first housing 10 and the second housing 20 are fitted together in the first direction A, and the cover 30 is connected to the first housing 10 and the second housing 20 in the second direction B, thereby forming a closure of the receiving cavity 60. The electronic control board 40 is located inside the receiving cavity 60, and when the cover 30 is connected to the first housing 10 and the second housing 20, one end of the handle 50 located inside the receiving cavity 60 can abut against the electronic control board 40 to confine the electronic control board 40 within the receiving cavity 60, thus preventing the electronic control board 40 from moving within the receiving cavity 60. The other end of the handle 50 extends through the cover 30 to facilitate the user to lift and open the cover 30.

[0040] According to an embodiment of the present invention, the control box 100 has a handle 50 on the cover 30. One end of the handle 50 protrudes from the cover 30 to facilitate the user's lifting and opening of the cover 30, providing convenience for the installation and maintenance of the control box 100. At the same time, the end of the handle 50 located in the receiving cavity 60 can abut against the control board 40 inside the receiving cavity 60 to fix and limit the control board 40 in the receiving cavity 60, increasing the reliability and stability of the installation of the control board 40, avoiding the situation where the control board 40 becomes loose and comes into contact with the cover 30, which could cause a short circuit, and improving the safety of the control box 100.

[0041] In some embodiments, as Figure 2 and Figure 8As shown, a slot 51 is formed at one end of the handle 50 near the center of the receiving cavity 60 along the second direction B, and the end of the electronic control board 40 away from the center of the receiving cavity 60 along the second direction B is engaged in the slot 51. That is, the end of the handle 50 located inside the receiving cavity 60 has the slot 51. When the cover 30 is connected to the first box 10 and the second box 20, the slot 51 abuts against the edge of the electronic control board 40 located inside, thus limiting the movement of the electronic control board 40. Therefore, the cooperation between the slot 51 and the electronic control board 40 effectively reduces the movement of the electronic control board 40 in the first direction A and the second direction B, increases the stability of the electronic control board 40 installation, and reduces the possibility of the electrical connection wires connected to the electronic control board 40 becoming detached or the electronic control board 40 malfunctioning due to loose installation.

[0042] In some embodiments, refer to Figure 8 The control board 40 can extend along a third direction C, which is orthogonal to the second direction B and the first direction A. The handle 50 has two protrusions 52 spaced apart along the first direction A at one end near the center of the receiving cavity 60 along the second direction B, and a slot 51 is defined between the two protrusions 52. The slot 51 includes a first slot segment 511 and a second slot segment 512 that are connected to each other along the second direction B. The second slot segment 512 is connected to one end of the first slot segment 511 near the center of the receiving cavity 60. That is, the second slot segment 512 and the first slot segment 511 are arranged sequentially along the second direction B toward the direction away from the center of the receiving cavity 60. The end of the second slot segment 512 away from the first slot segment 511 is open, and the width of the second slot segment 512 gradually decreases along the side away from the center of the receiving cavity 60. The opening area of ​​the side of the second slot segment 512 near the center of the receiving cavity 60 is larger than the opening area of ​​the side away from the center of the receiving cavity 60. The second slot segment 512 has a good guiding effect so that the end of the electronic control board 40 away from the center of the receiving cavity 60 along the second direction B can pass smoothly through the second slot segment 512 and fit into the first slot segment 511. Therefore, the slot 51 includes a first slot section 511 and a second slot section 512. The second slot section 512 is open on the side away from the first slot section 511 and gradually increases in size along the second direction B toward the center of the receiving cavity 60. The second slot section 512 can have a guiding function so that when the handle 50 abuts against the electronic control board 40, the electronic control board 40 can be smoothly fitted into the groove, increasing the convenience of installing the cover 30. At the same time, it can effectively avoid the possibility of the electronic control board 40 interfering with the installation of the cover 30 during the installation process, and reduce the possibility of the cover 30 damaging the electronic control board 40.

[0043] Optionally, such as Figure 5 and Figure 7As shown, the handle 50 includes a first handle portion 53 and a second handle portion 54 connected to each other. The first handle portion 53 and the second handle portion 54 are connected to each other along a second direction B. After the handle 50 is engaged with the cover 30, the first handle portion 53 can extend through the cover 30 to the side of the cover 30 away from the center of the receiving cavity 60. The first handle portion 53 engages with the cover 30 to at least limit the movement of the first handle portion 53 in the first direction A. The second handle portion 54 can be located within the receiving cavity 60. The second handle portion 54 engages with the cover 30 to limit the movement of the second handle portion 54 in the second direction B and a third direction C. The third direction C, the second direction B, and the first direction A are orthogonal. The cover 30 can form a limit on the first handle portion 53 and the second handle portion 54 to limit the movement of the first handle portion 53 and the second handle portion 54 in the first direction A to the third direction C, respectively. Specifically, the second handle 54 can be disposed between the cover 30 and the electronic control board 40, and the cover 30 and the electronic control board 40 can simultaneously abut against it. The first handle 53 is disposed between the cover 30 and the second handle 54, and the cover 30 limits the first handle 53 at least in the second direction B and the third direction C. Combined with the second handle 54, the first handle 53 can be limited in the first direction A.

[0044] Therefore, the handle 50 includes a first handle portion 53 and a second handle portion 54 connected to each other. Since the first handle portion 53, after engaging with the cover 30, is limited to moving in the first direction A, and the second handle portion 54, after engaging with the cover 30, is limited to moving in the second direction B and the third direction C, the cover 30 can limit the movement of the handle 50 from the first direction A to the third direction C, thereby completing the limiting of the handle 50, increasing the reliability of the handle 50 installation, as well as the integrity of the handle 50 and the cover 30, and improving the structural strength of the handle 50.

[0045] In some embodiments, as Figure 6 and Figure 7As shown, a first limiting groove 31 is formed on the cover 30. The first limiting groove 31 is formed by recessing one side surface of the cover 30 along the third direction C toward the other side surface of the cover 30 along the third direction C. A first handle portion 53 is fitted into the first limiting groove 31 to limit the movement of the first handle portion 53 in the first direction A. At least one of the two side walls of the first limiting groove 31 along the first direction A is provided with a limiting rib 311. The limiting rib 311 is spaced apart from the bottom wall of the first limiting groove 31. One end of the limiting rib 311 is connected to one of the side walls of the first limiting groove 31. There can be two limiting ribs 311, which are respectively provided on the two side walls of the first limiting groove 31 along the first direction A. A portion of the first handle portion 53 is located between the limiting rib 311 and the first limiting groove 31 to limit the movement of the first handle portion 53 in the third direction C. When the cover 30 is connected to the first box 10 and the second box 20, the first limiting groove 31 is located at one end of the cover 30 and the first box 10 and the second box 20 in the third direction C. The first handle 53 extends through the first limiting groove 31 toward the cover 30 away from the center of the receiving cavity 60. The limiting rib 311 can limit the first handle 53 in the third direction C. The first handle 53 is provided with a reinforcing rib 532 along the third direction C away from the center of the receiving cavity 60. The reinforcing rib 532 is located inside the receiving cavity 60 and abuts against the limiting rib 311, so that the limiting rib 311 can limit the first handle 53 in the second direction B.

[0046] Therefore, a first limiting groove 31 and a limiting rib 311 connected to one side wall of the limiting groove are provided on the cover 30. The first limiting groove 31 can cooperate with the first handle 53 to realize the installation of the first handle 53. The limiting rib 311 can limit the first handle 53, prevent the first handle 53 from moving along the first direction A and the third direction C, increase the limitation of the first handle 53, facilitate the installation of the first handle 53, so that the first handle 53 has high structural strength and facilitates the smooth opening and closing of the cover 30.

[0047] Furthermore, such as Figure 3As shown, the electrical control box 100 also includes: a third box body 70, which is disposed within the receiving cavity 60. One end of the third box body 70 adjacent to the cover 30 is open. The electrical control board 40 is removably disposed within the third box body 70. The cover 30, the first box body 10, and the second box body 20 are all sheet metal parts, the third box body 70 is a plastic part, and the handle 50 is a flame-retardant plastic part. During the assembly of the electrical control box 100, the first box body 10 and the second box body 20 are assembled and define the receiving cavity 60. The third box body 70 is assembled within the receiving cavity 60 and is connected to the first box body 10 and the second box body 20. A sliding groove is defined within the third box body 70. The electrical control board 40 cooperates with the sliding groove, and the electrical control board 40 is removable relative to the sliding groove. Closing the cover 30 achieves the closure of the receiving cavity 60. At the same time, one end of the handle 50 located within the receiving cavity 60 abuts against the circuit board, thus limiting the electrical control board 40. The sheet metal parts can specifically be 0.5mm galvanized steel sheets. The material of the third box 70 can be flame-retardant ABS (Acrylonitrile Butadiene Styrene) with a flame-retardant rating of 5VA or flame-retardant BMC (Bulk Molding Compound), and there are no restrictions here. Therefore, the third box 70 is located within the receiving cavity 60, and the control board 40 is removable relative to the third box 70, facilitating the installation of the control board 40. Simultaneously, it allows for easy disassembly and timely repair in case of a malfunction, reducing maintenance and operating costs. The first box 10, the second box 20, and the cover 30 are all sheet metal parts, which improves the structural strength of the control box 100. The relatively thin sheet metal parts also provide good fire resistance, ensuring the structural integrity of the control box 100 even when exposed to fire, while simultaneously reducing manufacturing costs. The third box 70 located in the receiving cavity 60 is made of plastic, which can make the third box 70 have insulation properties, reducing the risk of short circuit of the electrical control board 40. The handle 50 is made of flame-retardant plastic, which can prevent the handle 50 from being burned or delay the burning of the handle 50, increase the service life of the handle 50, and reduce losses.

[0048] In some embodiments, refer to Figure 4 and Figure 7The third housing 70 is provided with a mounting post 71, and the first handle portion 53 is provided with a mounting portion 531, which is located on the side of the cover 30 adjacent to the center of the receiving cavity 60. The electrical control box 100 further includes a threaded fastener, which passes through the cover 30, the mounting portion 531, and is threadedly connected to the mounting post 71. That is, the first handle portion 53 is provided with a mounting portion 531 on the side adjacent to the center of the receiving cavity 60, and the mounting portion 531 is provided with a through hole 533. The through hole 533 is opposite to the mounting post 71 on the third housing 70 in the second direction B. The threaded fastener passes through the top of the cover 30 and cooperates with the through hole 533 and the mounting post 71 to connect the cover 30, the mounting portion 531, and the third housing 70 to fix the mounting portion 531. Therefore, the mounting post 71 on the third housing 70 facilitates the connection between the threaded fasteners passing through the cover 30 and the mounting part 531 to the mounting post 71, thereby increasing the reliability of the third housing 70 and the mounting part 531 installed in the receiving cavity 60.

[0049] In some embodiments, combined with Figure 5 and Figure 7The edge of the cover 30 has a flange 32 extending toward the center of the receiving cavity 60, and a locking hole 321 is formed on the flange 32; the second handle portion 54 is located on the side of the flange 32 adjacent to the center of the cover 30, and the side of the second handle portion 54 away from the center of the cover 30 is provided with a plurality of spaced-apart limiting portions 541, one end of each limiting portion 541 adjacent to the center of the receiving cavity 60 is connected to the second handle portion 54, and the other end of each limiting portion 541 extends toward the direction away from the center of the receiving cavity 60 and is spaced apart from the surface of the side of the second handle portion 54 away from the center of the cover 30 to define a second limiting groove 542, and the flange 32 fits in the second limiting groove 542; the second handle portion 54 is provided with a buckle 543, and the buckle 543 cooperates with the locking hole 321 to limit the movement of the second handle portion 54 in a third direction C toward the direction away from the center of the receiving cavity 60. That is, the second handle portion 54 is provided with a plurality of limiting portions 541 on the side away from the center of the receiving cavity 60. Here, we will describe two limiting portions 541. The two limiting portions 541 are arranged at intervals along the first direction A. The end of the limiting portion 541 near the center of the receiving cavity 60 is connected to the surface of the second handle portion 54 away from the center of the receiving cavity 60. The limiting portions 541 and the surface of the second handle portion 54 away from the center of the receiving cavity 60 are arranged at intervals. The second limiting groove 542 defined by the two limiting portions 541 and the second handle portion 54 can cooperate with the flange 32 of the cover 30 to facilitate the installation of the second handle portion 54 and the cover 30. The buckle 543 provided on the second handle 54 extends in the second direction B toward the direction away from the center of the receiving cavity 60, and the free end of the buckle 543 extends obliquely toward the limiting part 541 toward the side of the second handle 54 away from the center of the receiving cavity 60. When the handle 50 and the cover 30 are engaged, the buckle 543 can engage with the locking hole 321 on the flange 32, thereby fixing the handle 50 and the cover 30.

[0050] Therefore, a locking hole 321 is provided on the cover 30, and a buckle 543 and a limiting part 541 are provided on the second handle part 54. The buckle 543 can cooperate with the locking hole 321 to install the handle 50, and the limiting part 541 can increase the stability of the installation between the handle 50 and the cover 30. The structure for connecting the cover 30 and the handle 50 is simple and facilitates the assembly and disassembly of the handle 50 and the cover 30.

[0051] In some embodiments, as Figure 4 and Figure 9As shown, the first box body 10 has a folded edge 11 at one end adjacent to the cover body 30 along the second direction B. The folded edge 11 includes a first side and a second side stacked along the thickness direction, i.e., the second direction B, with the first side and the second side spaced apart. At least one grounding hole 111 is formed on the folded edge 11. The grounding hole 111 facilitates the connection of the connection terminals on the control board 40 to the grounding hole 111 via wires, increasing the safety of the control box 100 and protecting the control board 40. Therefore, the folded edge 11 on the side of the first box body 10 adjacent to the cover body 30 improves the structural strength at the folded edge 11, prevents the grounding hole 111 from failing, and helps the control box 100 meet structural strength and design requirements while reducing the amount of material used in manufacturing the control box 100 and lowering production costs.

[0052] In addition, combined Figure 3 The overlapping edge 11 with grounding hole 111 is also provided with a first connecting hole 112. The cover 30 is provided with a second connecting hole 33 opposite to the first connecting hole 112. The first connecting hole 112 and the second connecting hole 33 are opposite to each other along the second direction B. The connection between the first connecting hole 112 and the second connecting hole 33 can be achieved by threaded fasteners, realizing the fixed connection between the cover 30 and the first box 10, and improving the structural reliability of the electrical control box 100. The first box 10 and the second box 20 are also provided with multiple hooks 12 and multiple latches 21 (not shown in the figure). The multiple hooks 12 and latches 21 are arranged at intervals along the circumference of the first box 10 and the second box 20. For example, hooks 12 are provided on the first box 10 and latches 21 are provided on the second box 20. When the first box 10 and the second box 20 are assembled, the latches 21 cooperate with the hooks 12, increasing the reliability of the connection between the first box 10 and the second box 20.

[0053] According to a second aspect embodiment of the present invention, an air conditioner 1000 includes an electrical control box 100 according to any of the above embodiments.

[0054] According to an embodiment of the present invention, the air conditioner 1000, by providing a handle 50 on the electrical control box 100, facilitates the opening and closing of the cover 30 of the electrical control box 100, making inspection and maintenance of the electrical control box 100 easier and reducing the difficulty of inspection and maintenance. Furthermore, the handle 50 can limit and stop the electrical control board 40 inside the electrical control box 100, ensuring reliability while facilitating production assembly and improving product stability.
