Description

Technical Field

[0001] The present invention relates to the technical field of electrical boxes, and in particular, to an electrical box and an indoor unit of an air conditioner. Background Art

[0002] The electrical box is an important component of the indoor unit of an air conditioner. The electrical box mainly includes components such as a box body, a box cover, a PCB fixing plate, a circuit board, and electrical components. Among them, the PCB fixing plate is fixed inside the box body, the electrical components and the circuit board are fixed on the PCB fixing plate, and the box cover covers the box body.

[0003] In the electrical box in the prior art, in order to facilitate the assembly of the PCB fixing plate into the box body, a relatively large gap is reserved between the PCB fixing plate and the box body. However, in this kind of assembly structure, after the PCB fixing plate is assembled into the box body, not only is the gap between the PCB fixing plate and the box body relatively large, resulting in poor airtightness of the electrical box, but also the overall size of the electrical box is relatively large, which is not conducive to the arrangement of the other components of the indoor unit.

[0004] Alternatively, in order to facilitate the assembly of the PCB fixing plate into the box body, a baffle is not provided on one side of the PCB fixing plate, that is, the PCB fixing plate is only provided with baffles on three sides. This kind of assembly structure also results in poor airtightness of the electrical box, and there is a hidden danger of flames escaping when the main board is burned due to reasons, and the fire prevention performance of the electrical box is poor.

[0005] Currently, most of the electrical box structures are in the form of a single electrical box, that is, a whole circuit board and all electrical components are arranged in a single box body. This single box body structure results in low space utilization rate of the electrical box, and thus it is difficult to ensure the compactness of the internal structure of the electrical box. Not only is it easy to cause the overall size of the electrical box to be relatively large, but it is also difficult to ensure the airtightness of the electrical box. Summary of the Invention

[0034] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0035] It should be pointed out that the following detailed description is illustrative and is intended to provide further description of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0036] It should be noted that the terms used herein are only for describing specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0037] The present invention provides an electrical box. Please refer to Figures 1 to 6 , the electrical box includes a plurality of boxes 10 and a box cover 20. Each box 10 is used to accommodate at least one circuit board 50, and at least one box 10 is used to accommodate electrical components; the plurality of boxes 10 are stacked in sequence along a preset direction; each box 10 has a preset opening, and the box cover 20 is covered on the plurality of boxes 10 to block the preset openings of the plurality of boxes 10.

[0038] In the electrical box of the present invention, the electrical box includes a plurality of boxes 10 and a box cover 20, and the plurality of boxes 10 are stacked in sequence along a preset direction; each box 10 is used to accommodate at least one circuit board 50, and at least one box 10 is used to accommodate electrical components, that is, at least one box 10 contains a circuit board 50 and electrical components, and the remaining boxes 10 only contain circuit boards 50; each box 10 has a preset opening to enable the circuit board 50 in each box 10 to enter and exit the box 10 through its preset opening. When the box 10 is used to accommodate electrical components, the electrical components enter and exit the corresponding box 10 through the preset opening of the corresponding box 10. After the circuit board 50 and the electrical components are both installed in the corresponding box 10, the box cover 20 is covered on the plurality of boxes 10 so that the box cover 20 blocks the preset openings of the plurality of boxes 10, thereby ensuring the tightness of each box 10.

[0039] The electrical box of the present invention sets a plurality of boxes 10 to separately arrange different circuit boards 50 in the plurality of boxes 10, that is, adopts a way of dividing the whole into parts to improve the utilization rate of the internal space of each box 10, and further makes the internal structure of each box 10 relatively compact, which is beneficial to reducing the overall size of the electrical box and is beneficial to ensuring the tightness of the electrical box, and solves the problem of low utilization rate of the internal space of the electrical box in the prior art.

[0040] It should be noted that compared with the prior art in which a whole circuit board is arranged in a box, when the whole electrical box works at high power, the generated heat is relatively concentrated, so the heat generation rate is high; while the multiple circuit boards 50 of this electrical box are dispersedly arranged, that is, the heat generated by each circuit board 50 is relatively dispersed, so the overall heat generation rate of the electrical box is lower. When a fire breaks out due to the burning of the circuit board 50 inside each box 10, since the internal space of each box 10 is small and the tightness is good, that is, the oxygen content in each box 10 is limited, the burning flame is not easy to expand and goes out in a short time, which is beneficial to improving the fire prevention performance of this electrical box, and thus improving the use safety of this electrical box. In addition, the good tightness can also prevent insects and the like from entering the box 10.

[0041] Specifically, the multiple boxes 10 include a first box 11 and a second box 12. The first box 11 is used to accommodate electrical components and the corresponding circuit board 50, and the second box 12 is used to accommodate the corresponding circuit board 50. The second box 12 is at least one. When there is one second box 12, the first box 11 is arranged on the second box 12. When there are multiple second boxes 12, the multiple second boxes 12 are stacked in sequence along a preset direction, and the first box 11 is arranged on the second box 12 at the end among the multiple second boxes 12.

[0042] It should be noted that when there are multiple second boxes 12, along the preset direction, the first box 11 is arranged on the second box 12 at the first end position or the second box 12 at the last end position among the multiple second boxes 12. For example, the multiple second boxes 12 are arranged in sequence along the vertical direction, and the first box 11 is arranged on the second box 12 at the top among the multiple second boxes 12.

[0043] In this embodiment, the first box 11 has a top surface and a bottom surface arranged oppositely, and the bottom surface of the first box 11 is in contact with the second box 12. The preset opening of the first box 11 is a first preset opening 111, and the first preset opening 111 is arranged on the top surface of the first box 11. As Figure 3 shown, the top opening of the first box 11 is the first preset opening 111, and the first box 11 is a cuboid.

[0044] The second box 12 has multiple side surfaces, and the multiple side surfaces of the second box 12 are arranged around the preset direction. The preset opening of the second box 12 is a second preset opening 121, and the second preset opening 121 is arranged on one side surface of the second box 12. For example, as Figure 4 shown, the second box 12 is a cuboid, the second box 12 has four side surfaces, and the second preset opening 121 is arranged on one of the four side surfaces of the second box 12.

[0045] In this embodiment, the box cover 20 includes a main cover plate 21 and a side cover plate 22 connected to each other. The main cover plate 21 is covered at the first preset opening 111 on the first box 11 so that the main cover plate 21 forms an occlusion for the first preset opening 111.

[0046] Specifically, when there is one second box 12, there is one side cover plate 22, and the side cover plate 22 is covered at the second preset opening 121 on the second box 12 so that the side cover plate 22 forms an occlusion for the second preset opening 121.

[0047] Specifically, when there are multiple second boxes 12, the side cover plate 22 is one or more.

[0048] More specifically, when there are multiple second boxes 12 and the sides where the multiple second preset openings 121 are located are on the same side of the multiple second boxes 12, there is one side cover plate 22 to shield all the multiple second preset openings 121; when there are multiple second boxes 12 and the sides where the multiple second preset openings 121 are located are on multiple sides of the multiple second boxes 12, there are multiple side cover plates 22, and the multiple side cover plates 22 are respectively disposed on multiple sides of the multiple second boxes 12 in a one-to-one correspondence to shield the second preset openings 121 on the corresponding sides of the multiple second boxes 12.

[0049] For example, when each of the second boxes 12 is a cuboid, the four sides of each second box 12 are respectively a first side 123, a second side, a third side, and a fourth side. When the second preset openings 121 of each second box 12 are all on its first side 123, there is one side cover plate 22. When at least one second preset opening 121 is provided on the first side 123 of the corresponding second box 12, at least one second preset opening 121 is provided on the second side of the corresponding second box 12, at least one second preset opening 121 is provided on the third side of the corresponding second box 12, and at least one second preset opening 121 is provided on the fourth side of the corresponding second box 12, there are four side cover plates 22, and the four side cover plates 22 respectively shield at least one second preset opening 121 on the first side 123, at least one second preset opening 121 on the second side, at least one second preset opening 121 on the third side, and at least one second preset opening 121 on the fourth side.

[0050] In this embodiment, as Figure 3 shown, at least one wire passing hole 112 is provided on the side wall of the first box 11. Optionally, along the circumference of the wire passing hole 112, at least part of the hole wall of the wire passing hole 112 is an arc surface; for example, the wire passing hole 112 is a circular hole or an oval hole.

[0051] Specifically, a sealing gasket 113 is provided on the hole wall of the wire passing hole 112 so that the sealing gasket 113 wraps the hole wall of the wire passing hole 112, which is beneficial to ensuring the airtightness of the first box 11. Optionally, the sealing gasket 113 is a rubber gasket.

[0052] In this embodiment, the multiple sides of the second box 12 include a first side 123 and a second side that are connected to each other. The second preset opening 121 is provided on the first side 123, a wire leading port 122 is provided on the second side, and the second preset opening 121 is communicated with the wire leading port 122.

[0053] Specifically, the second preset opening 121 extends to the outer periphery of the first side surface 123 near the second side surface, and the lead wire opening 122 extends to the outer periphery of the second side surface near the first side surface 123, so that the second preset opening 121 is directly communicated with the lead wire opening 122.

[0054] Optionally, a part of the predetermined circular opening forms the lead wire opening 122. For example, the lead wire opening 122 is a semicircular opening.

[0055] In traditional electrical boxes, the wire passing opening is usually arranged on the box cover of the electrical box. When the box cover of the electrical box is disassembled, the wire passing coil in the wire passing opening on the box cover is likely to fall off. Or, the wire passing coil and the box body are connected by a buckle. On the one hand, there is a gap at the buckle, and gas is easy to flow through, resulting in poor airtightness of the electrical box; on the other hand, the buckle is usually arranged on the outside of the electrical box, so that the buckle is easily affected by other components and falls off from the mounting hole, resulting in the wire passing coil being easily detached. The structural settings of the wire passing hole 112 and the lead wire opening 122 of the electrical box in this application avoid the use of components such as buckles and avoid the phenomenon that the wire passing coil is easily detached.

[0056] In this embodiment, as Figure 1 and Figure 6 shown, a support member 30 is arranged in the first box body 11. The support member 30 includes a plurality of first support portions 31, so that the circuit board 50 in the first box body 11 is arranged on the plurality of first support portions 31.

[0057] Specifically, the support member 30 further includes a fixing plate 32. The plurality of first support portions 31 are arranged on the fixing plate 32, and electrical components are fixed on the fixing plate 32. Optionally, the support member 30 is an injection molded part.

[0058] In this embodiment, as Figure 4 and Figure 5 shown, two second support portions 40 are arranged on the inner wall of the second box body 12. The two second support portions 40 are arranged oppositely, so that the circuit board 50 in the second box body 12 is slidably arranged along the two second support portions 40. For example, when the second box body 12 is a cuboid, the plurality of side surfaces of the second box body 12 include a second side surface, a first side surface 123, and a third side surface that are connected in sequence. The second side surface and the third side surface are arranged oppositely, and the two second support portions 40 are respectively arranged on the inner walls of the second side surface and the third side surface, so that the circuit board 50 in the second box body 12 can slide into or out of the second box body 12 through the second preset opening 121 on the first side surface 123.

[0059] Specifically, each second support portion 40 includes a first strip-shaped plate 41, and the first strip-shaped plate 41 is disposed on the inner wall of the second box body 12, so that the circuit board 50 in the second box body 12 is slidably disposed on the first strip-shaped plates 41 of the two second support portions 40, that is, the first strip-shaped plates 41 of the two second support portions 40 jointly support the circuit board 50 in the second box body 12.

[0060] Specifically, each second support portion 40 further includes a second strip-shaped plate 42, and the second strip-shaped plate 42 is disposed opposite to the corresponding first strip-shaped plate 41, so as to form a slideway 43 for the circuit board 50 in the second box body 12 to slide between the second strip-shaped plate 42 and the corresponding first strip-shaped plate 41. It should be noted that the extending direction of the first strip-shaped plate 41 is parallel to the extending direction of the second strip-shaped plate 42, and the circuit board 50 in the second box body 12 slides along the extending direction of the first strip-shaped plate 41.

[0061] Specifically, the distribution directions of the connecting end and the free end of each first strip-shaped plate 41 are perpendicular to its extending direction; from the connecting end to the free end of each first strip-shaped plate 41, each first strip-shaped plate 41 gradually approaches the corresponding second strip-shaped plate 42, that is, each first strip-shaped plate 41 is inclined. The distribution directions of the connecting end and the free end of each second strip-shaped plate 42 are perpendicular to its extending direction; from the connecting end to the free end of each second strip-shaped plate 42, each second strip-shaped plate 42 gradually approaches the corresponding first strip-shaped plate 41, that is, each second strip-shaped plate 42 is inclined.

[0062] In this embodiment, at least one partition portion is disposed in the second box body 12, and the at least one partition portion divides the cavity of the second box body 12 into a plurality of accommodating cavities, and each accommodating cavity is used to accommodate the corresponding circuit board 50, that is, one second box body 12 can accommodate a plurality of circuit boards 50; for example, each second box body 12 is used to accommodate a plurality of circuit boards 50, and the plurality of circuit boards 50 and the plurality of accommodating cavities of the second box body 12 are arranged in one-to-one correspondence, so that each accommodating cavity accommodates the corresponding circuit board 50. Optionally, the partition portion is a partition board.

[0063] Specifically, when there is a second preset opening 121 on the second box body 12, the plurality of accommodating cavities of the second box body 12 communicate with the second preset opening 121 of the second box body 12; when there are a plurality of second preset openings 121 on the second box body 12, each accommodating cavity of the second box body 12 communicates with one of the plurality of second preset openings 121 on the second box body 12; wherein, when there are a plurality of second preset openings 121 on the second box body 12, the plurality of second preset openings 121 of the second box body 12 are respectively disposed on different sides of the second box body 12.

[0064] Specifically, two second support parts 40 are arranged in pairs, and multiple pairs of second support parts 40 are arranged in the second box body 12. The multiple pairs of second support parts 40 in the second box body 12 are arranged in multiple accommodation cavities of the second box body 12 one by one; wherein, the two second support parts 40 of each pair of second support parts 40 are arranged on the inner walls of the corresponding accommodation cavities.

[0065] In this embodiment, among any two adjacent box bodies 10, a plurality of first connection parts 61 are arranged on one box body 10, and a plurality of second connection parts 62 are arranged on the other box body 10. The plurality of first connection parts 61 and the plurality of second connection parts 62 are arranged in one-to-one correspondence, so that each first connection part 61 is connected to the corresponding second connection part 62, thereby realizing the connection between two adjacent box bodies 10.

[0066] Specifically, a plurality of welding points are arranged between two adjacent box bodies 10, so that the two adjacent box bodies 10 are welded.

[0067] Optionally, each first connection part 61 is a first welding part, and each second connection part 62 is a second welding part, so that two adjacent box bodies 10 are welded; wherein, each first welding part and the corresponding second welding part together form a welding point.

[0068] Optionally, each first welding part is a first welding hole, and each second welding part is a second welding hole.

[0069] Specifically, each box body 10 is processed by using a fireproof material; for example, each box body 10 is a sheet metal part.

[0070] Specifically, the first box body 11 has a plurality of side surfaces arranged around a preset direction, and a first flanging part 114 is arranged at the connection of any two adjacent side surfaces of the first box body 11, which is beneficial to ensuring the airtightness inside the first box body 11.

[0071] Specifically, along the preset direction, each side surface of the second box body 12 has a first end and a second end arranged oppositely, and second flanging parts 124 are arranged at both the first end and the second end of at least one side surface of the plurality of side surfaces of the second box body 12, which is beneficial to ensuring the airtightness inside the second box body 12.

[0072] The present invention also provides an indoor unit of an air conditioner, which includes the above-mentioned electrical box.

[0073] Specifically, when the electrical box includes a first box body 11 and a second box body 12, the circuit board 50 in the first box body 11 is mainly responsible for the main body operation of the indoor unit of the air conditioner, and the circuit board 50 in the second box body 12 is mainly responsible for other additional functions of the indoor unit of the air conditioner; for example, the circuit board 50 in the second box body 12 is used to be responsible for the voice loading function and / or the humidification loading function of the indoor unit of the air conditioner.

[0074] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects:

[0075] In the electrical box of the present invention, the electrical box includes a plurality of box bodies 10 and a box cover 20. The plurality of box bodies 10 are stacked in sequence along a preset direction; each box body 10 is used to accommodate at least one circuit board 50, and at least one box body 10 is used to accommodate electrical components, that is, at least one box body 10 contains a circuit board 50 and electrical components, and the remaining box bodies 10 only contain circuit boards 50; each box body 10 has a preset opening to enable the circuit board 50 in each box body 10 to enter and exit the box body 10 through its preset opening. When the box body 10 is used to accommodate electrical components, the electrical components enter and exit the corresponding box body 10 through the preset opening of the corresponding box body 10. After the circuit board 50 and the electrical components are both installed in the corresponding box body 10, the box cover 20 is set on the plurality of box bodies 10 to enable the box cover 20 to block the preset openings of the plurality of box bodies 10, thereby ensuring the airtightness of each box body 10.

[0076] The electrical box of the present invention sets a plurality of box bodies 10 to respectively arrange different circuit boards 50 in the plurality of box bodies 10, that is, adopts a way of dividing the whole into parts to improve the internal space utilization rate of each box body 10, and further makes the internal structure of each box body 10 relatively compact, solving the problem of low internal space utilization of the electrical box in the prior art.

[0077] It should be noted that the terms "first", "second", etc. in the specification, claims and above-mentioned drawings of this application are used to distinguish similar objects and do not have to be used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of this application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0078] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures.
