[0001] The present application relates to the technical field of kitchen appliances, and in particular to an electric control box and a kitchen air conditioner. BACKGROUND

[0002] With the increasing improvement of living quality, the environment comfort of the kitchen, as an indispensable part of family life, is also increasingly valued. The kitchen air conditioner not only can realize the function of extracting oil smoke, but also can realize the adjustment of the temperature of the kitchen, and gradually enters the public view.

[0003] At present, the kitchen air conditioner includes a smoke machine unit, an air conditioner unit and a control box. The smoke machine unit is used to extract oil smoke, the air conditioner unit is used to adjust the temperature, and the control box is used to control the operation of the smoke machine unit and the air conditioner unit. However, the kitchen air conditioner has a large volume and occupies a large space in the kitchen. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the present application provides an electric control box and a kitchen air conditioner to solve the problem of the large volume of the kitchen air conditioner in the related art.

[0005] In one aspect, the present application provides an electric control box applied to a kitchen air conditioner. The kitchen air conditioner includes an air conditioner unit and a smoke machine unit. The electric control box includes:

[0006] a box body having a receiving cavity;

[0007] a first circuit board and a second circuit board, both of which are arranged in the receiving cavity. The first circuit board is configured to control the air conditioner unit, and the second circuit board is configured to control the smoke machine unit;

[0008] a support arranged in the receiving cavity and connected with the box body. The support includes a first surface and a second surface arranged oppositely. The first circuit board is mounted on the first surface, and the second circuit board is mounted on the second surface.

[0009] In one possible implementation, the box body includes a box part and a first cover.

[0010] The box part has a receiving cavity formed inside. The box part is provided with a first opening communicating with the receiving cavity.

[0011] The first cover is arranged on the first opening and connected with the box part.

[0012] The support is connected with the inner wall of the box part, and one of the first circuit board and the second circuit board is opposite to the first opening.

[0013] In this structure, the staff can directly disassemble the first cover of the box body to maintain the circuit board opposite to the first opening.

[0014] In one possible implementation, the box portion has a side edge at least part of the opening edge in the circumferential direction of the first opening, the side edge being located outside the first opening, and the first cover being fixed to the side edge.

[0015] This structure allows the first cover to be reliably fixed to the box to seal the first opening by the cooperation between the side of the box at the first opening position and the first cover.

[0016] In one possible implementation, the side is a first flange that extends outward from at least a portion of the opening edge of the box portion in the circumferential direction of the first opening.

[0017] With this structure, the side panels of the box are relatively easy to install, and there is no need to weld or use other connection methods to fix the side panels to the main body of the box.

[0018] In one possible implementation, the kitchen air conditioner also includes a fresh air unit;

[0019] The electrical control box also includes a third circuit board, which is configured to control the fresh air unit. The third circuit board is located inside the receiving cavity and is connected to the inner wall of the box.

[0020] This structure, which also houses the third circuit board within the box, can further reduce the number of electrical control boxes, thus helping to further reduce the size of the kitchen air conditioner.

[0021] In one possible implementation, a first surface of the bracket is provided with a plurality of first mounting posts, each first mounting post abutting against a first circuit board, and the first circuit board is fixed to the plurality of first mounting posts by fasteners; and / or,

[0022] The second surface of the bracket is provided with a plurality of second mounting posts, each of which abuts against the second circuit board, and the second circuit board is fixed to the plurality of second mounting posts by fasteners.

[0023] In this structure, the first mounting post can create a gap between the first circuit board and the bracket, which is beneficial for the heat dissipation of the first circuit board; the second mounting post can create a gap between the second circuit board and the bracket, which is also beneficial for the heat dissipation of the second circuit board.

[0024] In one possible implementation, the support includes a first side end and a second side end disposed opposite to each other, the first side end and the second side end respectively abutting against two inner walls opposite to the box body.

[0025] This structure allows the bracket to support the two opposite side walls of the box, making the side walls less prone to deformation and improving the reliability of the electrical control box.

[0026] In one possible implementation, the bracket includes a frame and a connecting edge, the connecting edge extending parallel to the inner wall of the box and the bracket adjacent to it, the connecting edge surrounding the frame and the opposite sides forming the first side end and the second side end of the bracket respectively.

[0027] This structure ensures that the contact area between the support and the inner wall of the box is sufficient, thus guaranteeing the support effect of the support on the box.

[0028] In one possible implementation, the inner wall of the box body has a protrusion protruding into the receiving cavity, and the side end of the bracket is provided with a sliding groove, with the end of the protrusion located in the sliding groove and slidably connected to the sliding groove.

[0029] In this structure, the bracket can be guided during assembly through the cooperation between the protrusion and the groove, allowing the bracket to be inserted into the box smoothly.

[0030] On the other hand, this application also provides a kitchen air conditioner, including a housing, a range hood unit, an air conditioning unit and the aforementioned electrical control box. The range hood unit, the air conditioning unit and the electrical control box are all installed inside the housing. The air conditioning unit is electrically connected to the first circuit board of the electrical control box, and the range hood unit is electrically connected to the second circuit board of the electrical control box.

[0031] The electrical control box and kitchen air conditioner provided in this application have a housing cavity within the box. A first circuit board, a second circuit board, and a bracket are housed within the housing cavity. The first circuit board controls the air conditioning unit, and the second circuit board controls the range hood unit. The first and second circuit boards are respectively mounted on a first surface and a second surface opposite to each other on the bracket. This integration of the first circuit board for controlling the air conditioning unit and the second circuit board for controlling the range hood within the same electrical control box reduces the number of electrical control boxes required in the kitchen air conditioner, thus reducing the overall size of the air conditioner and facilitating its maintenance.

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0049] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0051] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0052] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0053] In existing technology, kitchen air conditioners include a range hood unit, an air conditioning unit, and a control box. The range hood unit extracts cooking fumes, the air conditioning unit regulates temperature, and the control box controls the operation of both units. However, kitchen air conditioners require multiple control boxes, each containing a circuit board to control the range hood and air conditioning units. These multiple control boxes occupy significant internal space, resulting in a bulky air conditioner and hindering maintenance.

[0054] After repeated consideration and verification, the inventors discovered that if the circuit boards used to control different units in a kitchen air conditioner are integrated into the same electrical control box, the number of electrical control boxes in the kitchen air conditioner can be reduced, which helps to reduce the size of the kitchen air conditioner and facilitates its maintenance.

[0055] In view of this, the inventors designed an electrical control box and a kitchen air conditioner. By placing both the first circuit board for controlling the range hood unit and the second circuit board for controlling the air conditioning unit inside the electrical control box, the number of electrical control boxes in the kitchen air conditioner can be reduced. Furthermore, a bracket is also provided inside the electrical control box, with the first circuit board mounted on two opposing surfaces of the bracket. This allows the first and second circuit boards to be stacked within the box, reducing the volume occupied by the first and second circuit boards and making the electrical control box smaller. This, in turn, helps reduce the size of the kitchen air conditioner and facilitates its maintenance.

[0056] The following describes in detail the technical solutions of the electrical control box and kitchen air conditioner provided in the embodiments of this application, with reference to the accompanying drawings.

[0057] Reference Figures 1 to 4 As shown in the embodiment of this application, the electrical control box 500 is applied to a kitchen air conditioner, which includes an air conditioning unit 200 and a range hood unit 400. The electrical control box 500 includes a box body 510, a first circuit board 521, a second circuit board 522, and a bracket 530. The box body 510 has a receiving cavity 511, wherein the box body 510 can be a box structure, which can protect the first circuit board 521, the second circuit board 522, and the bracket 530 inside.

[0058] The first circuit board 521 and the second circuit board 522 are both disposed in the receiving cavity 511. The first circuit board 521 is configured to control the air conditioning unit 200, and the second circuit board 522 is configured to control the range hood unit 400.

[0059] Schematic illustration: Air conditioning unit 200 includes a compressor, a supply fan, and a cooling fan. A first circuit board 521 can be electrically connected to the compressor, supply fan, and cooling fan respectively via cables to control their operation. Smoke hood unit 400 includes an exhaust fan. A second circuit board 522 can be electrically connected to the exhaust fan via cables to control its operation.

[0060] The bracket 530 is disposed in the receiving cavity 511 and connected to the box body 510. The bracket 530 includes a first surface and a second surface disposed opposite to each other. A first circuit board 521 is mounted on the first surface and a second circuit board 522 is mounted on the second surface.

[0061] For example, the bracket 530 can be an approximate plate-like structure, which can be fixed to the interior of the housing 510 by means of fasteners or snap-fitting. When the bracket 530 is a plate-like structure, the first surface and the second surface can be two opposite surfaces of the bracket 530. It is understood that the first circuit board 521 and the second circuit board 522 are located on opposite sides of the bracket 530, which is equivalent to the first circuit board 521 and the second circuit board 522 being stacked through the bracket 530. The first circuit board 521 and the second circuit board 522 can be fixed to the bracket 530 by means of fasteners, adhesives, or snap-fitting, etc., which is not the only possible method.

[0062] The electrical control box 500 provided in this embodiment integrates the first circuit board 521 for controlling the air conditioning unit 200 and the second circuit board 522 for controlling the range hood into the same box body 510. This helps to reduce the number of electrical control boxes 500 in the kitchen air conditioner, making it easier to reduce the size of the kitchen air conditioner and also making it easier to maintain.

[0063] In addition, the first circuit board 521 and the second circuit board 522 are respectively installed on opposite sides of the bracket 530, which helps to reduce the area occupied by the first circuit board 521, the bracket 530 and the second circuit board 522 inside the box 510, and helps to reduce the cross-sectional area of ​​the box 510, which facilitates the arrangement of the electrical control box 500.

[0064] In one embodiment, such as Figure 3 and Figure 4 As shown, the box body 510 includes a box portion 512 and a first cover 513. The box portion 512 has a receiving cavity 511 inside, and the box portion 512 has a first opening communicating with the receiving cavity 511.

[0065] The shape of the first opening matches the shape of the receiving cavity 511, and the first opening is located at the end of the box portion 512 facing the first cover 513. The first circuit board 521, the bracket 530, and the second circuit board 522 can be inserted into the receiving cavity 511 of the box portion 510 through the first opening.

[0066] A first cover 513 is placed over the first opening and connected to the box portion 512. A bracket 530 is connected to the inner wall of the box portion 512, and one of the first circuit board 521 and the second circuit board 522 is opposite to the first opening.

[0067] Understandably, the first cover 513 is used to close the first opening of the box 510. The shape of the first cover 513 can be the same as the shape of the first opening, and the area of ​​the first cover 513 is larger than the area of ​​the first opening. The first cover 513 can be fixed to the box 510 by fasteners or snap-fit ​​connections, etc., without being limited to a single method. For example, when the bracket 530 is a plate-like structure, the extending directions of the first circuit board 521, the bracket 530, and the second circuit board 522 are parallel to the extending direction of the first cover 513, respectively. When the first circuit board 521, the bracket 530, and the second circuit board 522 are placed in the receiving cavity 511, the first circuit board 521 or the second circuit board 522 is opposite to the first opening.

[0068] With the above setup, staff can directly disassemble the first cover 513 of the box 510 to maintain the circuit board opposite the first opening, thereby improving the maintenance efficiency of the electrical control box 500.

[0069] In a specific embodiment, such as Figure 4 As shown, the box portion 512 has at least a side edge on the circumferential edge of the first opening, and the side edge is located outside the first opening.

[0070] In one possible implementation, such as Figure 4 As shown, the side edge can be disposed around the first opening of the box portion 512; in another possible implementation, the side edge can be disposed on a portion of the edge of the first opening, for example, the two opposite edges of the first opening can each be provided with a side edge. The extending direction of the side edge is parallel to the extending direction of the first cover 513. For example, the side edge can be disposed on the box portion 510 by welding, bonding, or bending. It is worth noting that the side edge is located outside the first opening, meaning that the side edge does not reduce the area of ​​the first opening, and the side edge does not obstruct the operator from placing or removing the first circuit board 521, the first cover 513, and the second circuit board 522.

[0071] The first cover 513 is fixed to the side. Specifically, after the first cover 513 is placed on the side, it can be fixed to the side by means of fasteners or snap-fit ​​connection.

[0072] In this embodiment, the box portion 512 is provided with a side edge at the edge of the first opening. The side edge increases the contact area between the first cover 513 and the box portion 512, and the first cover 513 can be reliably fixed on the box portion 512 to seal the first opening.

[0073] In a more specific embodiment, such as Figure 4 As shown, the side is a first flange 5121 extending outward from at least a portion of the opening edge of the box portion 512 in the circumferential direction of the first opening.

[0074] Indicatively, the portion of the box 512 located at the edge of the first opening can be folded outward to form a first flange 5121. With the above configuration, the side of the box 512 is easier to set, and there is no need to weld or use other connection methods to fix the side to the body of the box 512.

[0075] like Figure 1 and Figure 2 As shown, the kitchen air conditioner also includes a fresh air unit 300. Schematic, the fresh air unit 300 includes a fresh air fan and fresh air ducts, and the fresh air fan can provide fresh air to the room through the fresh air ducts.

[0076] The electrical control box 500 also includes a third circuit board configured to control the fresh air unit 300. The third circuit board is disposed in the receiving cavity 511 and is connected to the inner wall of the box portion 512.

[0077] Schematic illustration: The third circuit board can be connected to the fresh air fan of the fresh air unit 300 via a cable, thereby controlling the operation of the fresh air unit 300. The third circuit board can be fixed to the inner side wall or the inner bottom wall of the box 512. In one specific embodiment, the third circuit board can be fixed to the inner side wall of the box 512 by fasteners, and the third circuit board is not likely to interfere with the first circuit board 521 or the second circuit board 522.

[0078] Integrating the third circuit board used to control the fresh air unit 300 into the interior of the housing 510 can further reduce the number of electrical control boxes 500 in the kitchen air conditioner, which is conducive to further reducing the size of the kitchen air conditioner.

[0079] In one possible implementation, the first surface of the bracket 530 is provided with a plurality of first mounting posts, each of which abuts against the first circuit board 521, and the first circuit board 521 is fixed to the plurality of first mounting posts by fasteners.

[0080] The first mounting post can be integrally molded onto the bracket 530. Optionally, one end of the first mounting post can be connected to the bracket 530, and the other end can abut against the first circuit board 521. The number of first mounting posts can be three, four, or five, etc., and is not limited here. Multiple first mounting posts are arranged parallel to each other, and the multiple first mounting posts are not located on the same straight line. After the multiple first mounting posts abut against the first circuit board 521, multiple fasteners can be used to pass through the first circuit board 521 and lock them one by one onto the multiple first mounting posts to fix the first circuit board 521 to the multiple first mounting posts.

[0081] In this embodiment, the first mounting post can create a gap between the first circuit board 521 and the bracket 530, which is beneficial for the heat dissipation of the first circuit board 521.

[0082] In another possible implementation, such as Figure 4 and Figure 5 As shown, the second surface of the bracket 530 is provided with a plurality of second mounting posts 535, each of the second mounting posts 535 abutting against the second circuit board 522, and the second circuit board 522 is fixed to the plurality of second mounting posts 535 by fasteners.

[0083] The second mounting post 535 can be integrally molded onto the bracket 530. One end of the second mounting post 535 can be connected to the bracket 530, and the other end of the second mounting post 535 can abut against the second circuit board 522. The number of second mounting posts 535 can also be three, four, or five, etc., with multiple second mounting posts 535 arranged parallel to each other, and the multiple second mounting posts 535 are not located on the same straight line.

[0084] Understandably, the second mounting post 535 can create a gap between the second circuit board 522 and the bracket 530, which is beneficial for the heat dissipation of the second circuit board 522.

[0085] In one possible implementation, the bracket 530 includes a first side end 533 and a second side end 534 disposed opposite to each other, the first side end 533 and the second side end 534 respectively abutting against two inner walls opposite to the housing 510.

[0086] For example, such as Figure 3 and Figure 4 As shown, box 510 is in Figure 3 and Figure 4 The top and bottom walls of the box have a large area, making them prone to deformation. The bracket 530 can extend along a direction perpendicular to the top wall of the box 510. The first side end 533 and the second side end 534 are respectively the bracket 530 in... Figure 3 and Figure 4 The top and bottom ends of the bracket 530 abut against the inner top wall of the box 510, and the bottom end of the bracket 530 abuts against the inner bottom wall of the box 510.

[0087] With the above configuration, the bracket 530 can support the two opposite side walls of the box 510, making the side walls of the box 510 less prone to deformation, which helps to improve the reliability of the electrical control box 500.

[0088] like Figure 4As shown, in one specific embodiment, the bracket 530 includes a frame 531 and a connecting edge 532, the extending direction of which is parallel to the inner wall of the box 510 adjacent to the bracket 530. Indicatively, the frame 531 can be a plate-like structure, and the extending direction of the connecting edge 532 can be perpendicular to the extending direction of the plate-like structure. Exemplarily, the connecting edge 532 can be integrally formed onto the frame 531. The width of the connecting edge 532 can be set as needed and is not uniquely limited here.

[0089] The connecting edge 532 is arranged around the frame 531, and its opposite sides form the first side end 533 and the second side end 534 of the bracket 530, respectively. That is to say, the opposite sides of the bracket 530 abut against the inner wall of the box 510 through the connecting edge 532. The connecting edge 532 ensures the contact area between the bracket 530 and the inner wall of the box 510, and ensures the supporting effect of the bracket 530 on the box 510.

[0090] like Figure 4 and Figure 6 As shown, the inner sidewall of the box body 510 has a protrusion 5122 protruding into the receiving cavity 511. For example, the sidewall of the box body 510 can be stamped so that a portion of the sidewall protrudes into the receiving cavity 511 to form a protrusion. There can be multiple protrusions 5122, and when the box body 510 has multiple protrusions 5122, the distance between the multiple protrusions 5122 and the first opening can be the same.

[0091] The side end of the bracket 530 is provided with a groove 536, and the end of the protrusion 5122 is located in the groove 536 and slidably connected to it. The number of grooves 536 is the same as the number of protrusions 5122, and each protrusion 5122 can extend into its corresponding groove 536. The grooves 536 can extend along the thickness direction of the bracket 530. When the operator places the first circuit board 521, the bracket 530, and the second circuit board 522 into the receiving cavity 511, as the bracket 530 moves to the position of the protrusion 5122, the protrusion 5122 extends into the corresponding groove 536, and slides within the groove 536 as the bracket 530 moves.

[0092] In this embodiment, during the assembly process, the bracket 530 can be guided by the cooperation between the protrusion 5122 and the slide groove 536, so that the bracket 530 can be smoothly placed into the box 510, thereby improving the assembly efficiency of the electrical control box 500.

[0093] This application also provides a kitchen air conditioner, including a housing 100, a range hood unit 400, an air conditioning unit 200, and the aforementioned electrical control box 500. The range hood unit 400, the air conditioning unit 200, and the electrical control box 500 are all installed inside the housing 100. The air conditioning unit 200 is electrically connected to the first circuit board 521 of the electrical control box 500, and the range hood unit 400 is electrically connected to the second circuit board 522 of the electrical control box 500.

[0094] For example, the housing 100 has a first inner cavity and a second inner cavity located below the first inner cavity. A partition is provided in the first inner cavity, dividing the first inner cavity into a first chamber and a second chamber. The air conditioning unit 200 may include an evaporator, a condenser, a compressor, a blower, and a cooling fan. The evaporator and the blower are installed in the first chamber. The blower can draw outside air from the housing 100 into the first chamber, cool it down by the evaporator, and then flow into the room to cool the kitchen. The condenser, compressor, and cooling fan are installed in the second chamber. The compressor can drive refrigerant to flow between the evaporator and the condenser. The cooling fan can draw indoor air into the second chamber, allow it to flow through the condenser, and then exhaust it to the outside to cool the condenser. The range hood unit 400 includes a smoke extraction fan, which can be installed in the second inner cavity. The electrical control box 500 can control the operation of the air conditioning unit 200 via a first circuit board 521 and can control the operation of the range hood unit 400 via a second circuit board 522.

[0095] The kitchen air conditioner provided in this embodiment uses the aforementioned control box 500. The two circuit boards in the control box 500 can control the range hood unit 400 and the air conditioning unit 200 respectively. It is not necessary to install multiple control boxes 500 in the kitchen air conditioner to control the range hood unit 400 and the air conditioning unit 200 respectively. The size of the kitchen air conditioner can be smaller, and it is also easier to maintain the kitchen air conditioner.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
