The invention provides an electric control box 1 which is used in an air conditioner. Referring to fig. 1 to 3, the electrical control box 1 includes an electrical control box main body 10, and a first fireproof plate 20, a second fireproof plate 30 and an electrical control box cover 50 disposed outside the electrical control box main body 10. The electric control box main body 10 comprises a first installation base body 11 and a second installation base body 12, wherein one end of the first installation base body 11 faces away from the direction of the first installation base body 11, and the first installation base body 11 and the second installation base body 12 form an included angle. In this embodiment, the first mounting base 11 and the second mounting base 12 each have a mounting space for accommodating components such as a circuit board and a wire holder, the mounting space has an opening, and the electrical control box cover 50 covers the opening. The first flame retardant panel 20 is provided on a side of the first mounting base 11 facing away from the second mounting base 12; the second fireproof plate 30 is arranged on the side edge of the second mounting base body 12 far away from the first mounting base body 11; the electrical control box cover 50 is arranged on one side surface of the second installation base body 12 far away from the first installation base body 11. In order to effectively prevent flame from escaping out of the electronic control box 1 when components in the electronic control box 1 are burnt, the first fireproof plate 20, the second fireproof plate 30 and the electronic control box cover 50 are arranged to jointly enclose a fireproof cavity, and the electronic control box main body 10 is located in the fireproof cavity.
The first flame retardant panel 20, the second flame retardant panel 30, and the electrically controlled box cover 50 are interconnected to form the flame retardant cavity. In this embodiment, the first flame retardant plate 20 and the second flame retardant plate 30 respectively surround the electrical box body 10 from two sides, and together with the electrical box cover 50, form the flame retardant cavity.
It should be noted that the fire-proof cavity may be a complete cavity or a cavity with an opening. Because some areas within the enclosure 1 are not vulnerable to fire based on practical testing, the fire-resistant chamber may be formed with one or more openings to save cost and simplify the manufacturing process of the first and second fire shield 20, 30.
According to the technical scheme, the first fire prevention plate 20, the second fire prevention plate 30 and the electronic control box cover 50 are arranged, and the first fire prevention plate 20, the second fire prevention plate 30 and the electronic control box cover 50 are enclosed to form a fire prevention cavity surrounding the electronic control box main body 10. When a fire breaks out in the electric control box 1, the fire-proof cavity can effectively prevent flame from escaping to the outside of the electric control box 1, so that the fire-proof performance of the electric control box 1 is improved, and the electric control box 1 can pass a fire-proof test; and the use safety of the air conditioner is improved. On the other hand, the fire-proof cavity of the technical scheme only comprises three main components, namely the fire-proof cavity is provided with fewer connecting parts, so that potential safety hazards caused by incomplete sealing of the connecting parts of two adjacent components can be reduced.
Referring to fig. 3 to 6, in order to connect the electrical box body 10 and the first and second fire- proof plates 20 and 30, a limiting member 13 is disposed at an edge of the electrical box body 10 close to the electrical box cover 50, and the limiting member 13 extends from the edge of the electrical box body 10 toward a direction away from the electrical box cover 50, so that a clamping gap is formed between the limiting member 13 and the electrical box body 10. The edge of the first fire prevention plate 20 and/or the second fire prevention plate 30 is provided with a limit notch 211 corresponding to the limit piece 13; the limiting notch 211 is tapered from the edge of the first flame retardant panel 20 and/or the second flame retardant panel 30 toward a direction away from the electrical box cover 50. The limiting notch 211 is clamped with the limiting part 13 through the clamping gap.
Specifically, the limiting notch 211 extends into the clamping gap and moves towards the direction of the electrical control box cover 50 until abutting against the limiting member 13; the retaining member 13 may thereby retain the first flame retardant panel 20 and/or the second flame retardant panel 30 against movement towards the electrical lid 50. Spacing breach 211 is from the edge of first PLASTIC LAMINATED 20 and/or second PLASTIC LAMINATED 30 is towards keeping away from the direction of automatically controlled lid 50 is the convergent setting to when first PLASTIC LAMINATED 20 and/or second PLASTIC LAMINATED 30 towards with the automatically controlled lid 50 direction is the both sides of angle and removes, one side of spacing breach 211 with locating part 13 butt is spacing in order to realize.
Further, the surface of the limiting member 13 facing the electrical control box main body 10 is gradually away from the electrical control box main body 10 from the edge of the electrical control box main body 10 toward the direction away from the electrical control box cover 50. The clamping gap is gradually increased towards the direction far away from the electric control box cover 50 by the arrangement, so that the limiting notch 211 is conveniently clamped, and the assembly efficiency is improved. On the other hand, as the first flame retardant plate 20 and/or the second flame retardant plate 30 is snapped into the latching gap, the first flame retardant plate 20 and/or the second flame retardant plate 30 gradually approaches the electrical box main body 10, and when the first flame retardant plate 20 and/or the second flame retardant plate 30 abuts against the retaining member 13, the first flame retardant plate 20 and/or the second flame retardant plate 30 also abuts against the electrical box main body 10. With this arrangement, the gap between the electrical box body 10 and the first and/or second flame retardant plates 20, 30 can be reduced, thereby providing better fire protection and reducing the volume of the electrical box 1.
The number of the limiting members 13 is preferably multiple, and the limiting members 13 are uniformly arranged along the edge of the electronic control box body 10 close to the electronic control box cover 50, so that the connection strength between the electronic control box body 10 and the first fireproof plate 20 and/or the second fireproof plate 30 is uniform. Correspondingly, the plurality of limiting notches 211 are arranged in one-to-one correspondence with the limiting parts 13.
In order to further limit the movement of the first flame retardant plate 20 and/or the second flame retardant plate 30 relative to the electrical box main body 10, a limiting protrusion 14 is arranged on the surface of the electrical box main body 10 facing the first flame retardant plate 20 and/or the second flame retardant plate 30, and a limiting hole 212 is arranged on the first flame retardant plate 20 and/or the second flame retardant plate 30; the limiting protrusion 14 extends into the limiting hole 212, and the limiting protrusion 14 abuts against the side wall of the electric control box cover, which is close to the limiting hole 212.
Based on the above embodiment, when the first fireproof plate 20 and/or the second fireproof plate 30 are/is snapped into the holding gap, under the action of gravity, the first fireproof plate has a tendency of moving towards a direction away from the electronic control box cover 50, so that the limiting hole 212 is disposed close to the side wall of the electronic control box cover 50 and abuts against the limiting protrusion 14; to limit movement of the first and/or second flame retardant panels 20, 30 away from the limit stop 13. The first and/or second flame retardant panels 20, 30 may be secured to the electrical enclosure body 10 by the engagement of the retaining members 13 and retaining protrusions 14. When the limiting member 13 is engaged with the limiting notch 211 and the limiting protrusion 14 abuts against the limiting hole 212, there is almost no gap between the first fireproof plate 20 and/or the second fireproof plate 30 and the electronic control box body 10, so that the connection interface formed by the connection method is small, and the influence of the connection position on the overall sealing performance of the electronic control box 1 can be reduced.
In order to make the first and second flame retardant plates 20, 30 more compatible with the electrical enclosure body 10, the gap between the electrical enclosure body 10 and the first and second flame retardant plates 20, 30 is reduced to improve the sealing performance of the electrical enclosure 1. The first fireproof plate 20 comprises a first base plate 21, a first side plate 22 extending from one side edge of the first base plate 21 to the second fireproof plate 30, and a first bottom plate 23 extending from the other side edge of the first base plate 21 to the second fireproof plate 30; the first bottom plate 23 is adjacent to the first side plate 22; i.e. the first base plate 23 is on the opposite side of the second mounting base 12. The second fireproof plate 30 includes a second plate body 31 and a second side plate 32 extending from a side of the second plate body 31 toward the first mounting base 11. By providing the first side plate 22 in connection with the second side plate 32; the first bottom plate 23 is connected to the second plate 31 to connect the first flame retardant plate 20 to the second flame retardant plate 30.
In this embodiment, the second plate 31 is further provided with a sealing flange 311, and the sealing flange 311 is disposed opposite to the second side plate 32. The sealing flange 311 may be connected to a side of the first flame retardant panel 20 remote from the first side panel 22. In this embodiment, the sealing flange 311 is connected to the main body 10 of the electronic control box. The arrangement is that no easy fire point exists on one side of the electric control box main body 10 close to the sealing flange 311; and a wire clamping groove 15 for fixing the outgoing/incoming wires of the electric control box is also arranged on the side.
The side edge of the first side plate 22 facing the second side plate 32 is provided with a fixing hole 221; the second fireproof plate 30 is provided with a fixing protrusion 321. Specifically, the fixing protrusion 321 is disposed on a surface of the second fireproof plate 30 facing away from the electronic control box main body 10; the fixing protrusion 321 extends into the fixing hole 221, and one side of the fixing protrusion 321, which is far away from the first fireproof plate 20, abuts against the fixing hole 221. One side of the fixing protrusion 321, which is far away from the first fireproof plate 20, abuts against the fixing hole 221, so that the first fireproof plate 20 can be limited to move towards the direction far away from the second fireproof plate 30, and a gap communicated with the electronic control box main body 10 does not exist at the joint of the fixing hole 221 and the fixing protrusion 321, so that the sealing performance of the electronic control box 1 is effectively ensured while the first fireproof plate 20 and the second fireproof plate 30 are connected.
Further, the fixing protrusion 321 is disposed in an arc surface shape from a side surface close to the first fireproof plate 20; in this embodiment, the surface of the fixing protrusion 321 is semi-spherical. The arrangement can facilitate the sliding of the fixing hole 221 along the surface of the fixing protrusion 321 until the side of the fixing protrusion 321 away from the first fireproof plate 20 abuts against the fixing hole 221, thereby facilitating the assembly of workers.
In this embodiment, the fixing protrusions 321 are multiple and arranged along the side edge of the second side plate 32 close to the first side plate 22, and the number of the fixing protrusions can be set according to actual requirements. Correspondingly, a plurality of fixing holes 221 are also provided.
Further, as the first flame retardant panel 20 moves toward the second flame retardant panel 30, the fixing hole 221 is engaged with the fixing protrusion 321; when the first flame retardant panel 20 continues to move toward the second flame retardant panel 30 due to external force or the like, the fixing hole 221 is separated from the fixing protrusion 321, and therefore the first side panel 22 further includes a retaining protrusion 222. The second side plate 32 further includes a stop member 322, a stop groove is formed between the stop member 322 and the second side plate 32, and the anti-falling protrusion 222 extends into the stop groove and abuts against the stop groove to limit the first fireproof plate 20 to move continuously toward the second fireproof plate 30.
In this embodiment, the stop 322 is disposed on a side of the fixing protrusion 321 away from the first fireproof plate 20; the anti-falling protrusion 222 is disposed on an edge of the first side plate 22 facing the second side plate 32. Due to the arrangement, when people assemble the anti-falling device, the relative positions of the stop grooves and the anti-falling protrusions 222 can be observed conveniently; and is convenient to disassemble.
The structure of the stopper 322 may be various; in this embodiment, the stop piece 322 is a stop piece formed by stamping from the surface of the second side plate 32 towards a direction away from the second plate 31, the stop groove is formed between the stop piece and the second side plate 32, and the anti-falling protrusion 222 is inserted from one side of the gap until abutting against the stop piece.
The edge of the first bottom plate 23, which is far away from the first base plate 21, is provided with a connecting flange 231 facing the electric control box cover 50 plate, the connecting flange 231 is also provided with the fixing hole 221, and the side edge of the second plate 31, which is far away from the electric control box cover 50 plate, is provided with the fixing protrusion 321. The connecting flange 231 is arranged to connect the fixing hole 221 with the fixing protrusion 321 from the side of the second plate 31 away from the electrical box cover 50, so as to improve the connecting tightness and sealing performance between the first bottom plate 23 and the second plate 31.
Referring to fig. 6 and 7, in order to reduce the size of the electrical control box main body 10, it is preferable to design the shapes of the first mounting base 11 and the second mounting base 12 according to the space and the mounting position required for accommodating the circuit board and the component. In this embodiment, the surface of the second mounting base 12 facing the second flame retardant panel 30 is irregularly shaped. Therefore, in order to make the second flame retardant plate 30 more closely contact with the electrical box main body 10, the second plate 31 of the second flame retardant plate 30 is also irregular. In order to simplify the manufacturing process, the second plate 31 is preferably formed by stamping, and in order to adapt to the shape of the electrical control box main body 10, a process hole 33 is formed on the second plate 31. In order to prevent the fabrication hole 33 from affecting the fire-proof performance of the electrical control box 1, the second fire-proof plate 30 further includes a sealing member 40 for sealing the fabrication hole 33.
Since the shape of the tooling holes 33 can be varied, the shape of the sealing member 40 can be varied accordingly. In this embodiment, the sealing member 40 includes a first sealing plate 41 and a second sealing plate 42 connected to the first sealing plate 41 at an angle; this arrangement allows the sealing member 40 to have a certain elasticity, so as to reduce the precision requirement of the second plate 31 during assembly and simplify the manufacturing process. At least two first sealing flanges 43 are arranged on the edge of the first sealing plate 41 and/or the edge of the second sealing plate 42, and the arrangement of the first sealing flanges 43 can enhance the connection sealing performance of the sealing element 40 and the second plate body 31.
The first sealing flange 43 is provided with a connecting sheet 431 for connecting the sealing element 40 and the second plate 31 and an auxiliary buckle 432; the second plate 31 is provided with a connecting hole 312 adapted to the connecting sheet 431 and an auxiliary hole 212 adapted to the auxiliary buckle 432. During assembly, the auxiliary hole 212 is first engaged with the auxiliary buckle 432, and the connecting piece 431 extends into the connecting hole 312 to be engaged with the connecting hole 312. At this time, the direction of the holding force of the auxiliary hole 212 and the auxiliary button 432 is opposite to the direction of the holding force of the connecting hole 312 and the connecting piece 432. In this way, the sealing member 40 is firmly fixed on the second plate 31, and the connection manner effectively ensures the sealing performance of the electronic control box 1 while realizing the connection between the sealing member 40 and the second plate 31.
