Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to an electrical control box and a kitchen air conditioner. Background Technology

[0002] As living standards continue to improve, the comfort of the kitchen, an indispensable part of family life, is receiving increasing attention. Kitchen air conditioners, which can not only remove cooking fumes but also regulate kitchen temperature, are gradually gaining popularity.

[0003] Currently, kitchen air conditioners consist of a range hood unit, an air conditioning unit, and a control box. The control box can be used to control the operation of the range hood unit and the air conditioning unit.

[0004] However, the components of the range hood unit and the air conditioning unit are connected to the circuit board in the control box via cables, which makes the wiring and cabling of the control box inconvenient and increases the difficulty of maintaining the control box. Utility Model Content

[0005] Based on this, this application provides an electrical control box and a kitchen air conditioner to solve the problem that the cables in the kitchen air conditioner are messy, which increases the difficulty of maintaining the electrical control box.

[0006] In a first aspect, this application provides an electrical control box, which is applied to a kitchen air conditioner, the kitchen air conditioner including a range hood unit and an air conditioning unit; the electrical control box includes:

[0007] The box body has a receiving cavity;

[0008] A bracket is installed inside the receiving cavity and connected to the housing body, dividing the receiving cavity into a first receiving cavity and a second receiving cavity;

[0009] A first circuit board is located in a first receiving cavity. The first circuit board is configured to control an air conditioning unit. The first circuit board is connected to one side of a bracket.

[0010] The second circuit board is located in the second receiving cavity. The second circuit board is configured to control the smoke machine unit. The second circuit board is connected to the other side of the bracket.

[0011] The box body has multiple through holes on its wall panel, including at least one first through hole and at least one second through hole. The first through hole is connected to the first receiving cavity, and the second through hole is connected to the second receiving cavity. The first through hole and the second through hole are located on the wall panel of the box body in different orientations.

[0012] In one possible implementation, the number of first through holes is at least two, and the at least two first through holes are located on the wall panels facing different directions of the box.

[0013] With this structure, the cables between different components of the air conditioning unit and the first circuit board can pass through different first through holes according to the wiring distance, which further facilitates the wiring and cabling of the electrical control box, and at the same time reduces the total wiring distance in the kitchen air conditioner.

[0014] In one possible implementation, there is one second through hole, which is located on two opposite wall panels of the box body, along with one of the first through holes.

[0015] With this structure, during use, the second through hole of the control box can face the side wall of the kitchen air conditioner, and the first through hole can face the middle of the kitchen air conditioner, so that the total wiring distance between the different components in the kitchen air conditioner and the circuit board in the control box is minimized.

[0016] In one possible implementation, the size of each through hole in the first direction is larger than the size of the through hole in the second direction, where the first and second directions are two mutually perpendicular directions on the wall panel where the through holes are located.

[0017] In this structure, the cables between the circuit board and the corresponding components have a certain degree of freedom in the through holes, making it easy for staff to adjust the cable positions.

[0018] In one possible implementation, each through hole is provided with a seal, which is annular and has a slit for the cable to pass through.

[0019] In this structure, when no cable is running through the through hole, the slit closes and the seal closes the corresponding through hole; when the slit is open, a cable can pass through.

[0020] In one possible implementation, the seal includes an annular wall that is fitted into the inner edge of the corresponding through hole;

[0021] The inner edge of the ring wall has at least two inwardly extending elastic baffles in the circumferential direction, and the at least two elastic baffles are connected to each other to cover the interior of the ring wall;

[0022] A slit is defined between two interlocking elastic baffles.

[0023] In this structure, when the cable has not passed through the inside of the ring wall, the opening is closed by the interlocking of the elastic baffles; when the cable passes through the inside of the ring wall, the opening is opened by the elastic deformation of the elastic baffles to allow the cable to pass through.

[0024] In one possible implementation, multiple elastic baffles are provided on opposite sides of the ring wall, and the elastic baffles on both sides of the ring wall are arranged in a staggered manner and abut against each other.

[0025] In this structure, when the cable passes through the inside of the ring wall, some of the elastic baffles undergo elastic deformation, causing the slit to open to allow the cable to pass through. The remaining elastic baffles do not deform, causing the remaining part of the slit to close, which helps improve the sealing of the through hole. In addition, the small area of ​​the elastic baffles makes it easier for the cable end connector to push against the elastic baffles, causing them to deform elastically.

[0026] In one possible implementation, a recess is formed on the outer wall of the box, and a through hole is formed in the area of ​​the recess.

[0027] This structure reduces the height of the seal protruding from the housing, making it less likely for the seal to interfere with other components of the kitchen air conditioner.

[0028] In one possible implementation, a connecting portion is formed between the side end of the support and the corresponding side wall of the box, and the connecting portion connects the first receiving cavity and the second receiving cavity.

[0029] In this structure, the cable between the first circuit board and the second circuit board can pass through the connecting part, which facilitates the electrical connection between the first circuit board and the second circuit board.

[0030] In one possible implementation, the side end of the bracket is provided with at least two spaced-apart connecting seats, the ends of which abut against the inner sidewall of the box, and the gap between two adjacent connecting seats defines a connecting portion.

[0031] In this structure, the bracket abuts against the inner wall of the box through at least two connecting seats, thereby forming a connection between two adjacent connecting seats.

[0032] Secondly, this application 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, air conditioning unit, and 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.

[0033] The electrical control box and kitchen air conditioner provided in this application include a bracket, a first circuit board, and a second circuit board installed within the box body. The bracket divides the box body's accommodating cavity into a first accommodating cavity and a second accommodating cavity, with the first and second circuit boards located within their respective accommodating cavities. A first through hole and a second through hole are respectively provided on the wall panels of the box body. The first through hole communicates with the first accommodating cavity, and the second through hole communicates with the second accommodating cavity. Furthermore, the first and second through holes are located on wall panels facing different directions within the box body. The first circuit board can be connected to external wiring through the first through hole, and the second circuit board can be connected to external wiring through the second through hole. The cables connected to the first and second circuit boards pass through the wall panels facing different directions within the box body. This facilitates the wiring and cabling of the electrical control box, thereby simplifying its maintenance. Attached Figure Description

[0049] 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 described embodiments are some, but not all, of the embodiments of this application. 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] In existing technology, kitchen air conditioners include a range hood unit, an air conditioning unit, and a control box. The control box controls the operation of both the range hood and air conditioning units. The control box has through holes for cables to pass through, and multiple circuit boards are housed within it. Components of the range hood unit and the air conditioning unit are connected to their respective circuit boards in the control box via cables, all passing through the same through hole. This wiring and routing of the control box is inconvenient and increases the difficulty of maintenance.

[0055] After repeated consideration and verification, the inventors discovered that if a bracket is installed in the middle of the control box, and circuit boards are installed on both sides of the bracket, with holes drilled on both sides of the box on different side panels, the cables connecting the circuit board on one side of the bracket to the corresponding components of the kitchen air conditioner can pass through the holes on that side of the box; similarly, the cables connecting the circuit board on the other side of the bracket to the corresponding components of the kitchen air conditioner can pass through the holes on the other side of the box. This facilitates wiring and maintenance of the control box.

[0056] In view of this, the inventors designed an electrical control box and a kitchen air conditioner. The control box divides the housing into a first housing cavity and a second housing cavity by installing a bracket within the box body. A first circuit board and a second circuit board are respectively installed on both sides of the bracket, with the first circuit board located in the first housing cavity and the second circuit board located in the second housing cavity. A first through hole and a second through hole are provided on the box body, with the first through hole communicating with the first housing cavity and the second through hole communicating with the second housing cavity. The first and second through holes are located on different wall panels of the box body. This allows cables between the first circuit board and corresponding components to pass through the first through hole, and cables between the second circuit board and corresponding components to pass through the second through hole, facilitating wiring and cabling within the control box.

[0057] 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.

[0058] Reference Figure 1 and Figure 2 As shown in the embodiment of this application, the electrical control box 500 is applied to a kitchen air conditioner, which includes a range hood unit 400 and an air conditioning unit 200. The signal terminal of the electrical control box 500 is used to control the range hood unit 400 and the air conditioning unit 200.

[0059] like Figures 3-5As shown, the electrical control box 500 includes a box body 510, a bracket 530, a first circuit board 521, and a second circuit board 522. The box body 510 has a receiving cavity 511. For example, the box body 510 includes a box portion and a first cover. The box portion is provided with the aforementioned receiving cavity 511 and a first opening communicating with the receiving cavity 511. The first cover covers the first opening and is connected to the box portion.

[0060] The bracket 530 is installed inside the receiving cavity 511 and connected to the box body 510. The bracket 530 divides the receiving cavity 511 into a first receiving cavity 5111 and a second receiving cavity 5112. For example, the bracket 530 can be an approximately sheet-like structure, and it can be installed in the middle of the receiving cavity 511, with the first receiving cavity 5111 and the second receiving cavity 5112 located on opposite sides of the bracket 530. The bracket 530 can be fixed to the box body 510 by means of adhesion, fasteners, or snap-fit ​​connections; no single method is limited here.

[0061] A first circuit board 521 is located within a first receiving cavity 5111. The first circuit board 521 is configured to control the air conditioning unit 200 and is connected to one side of a bracket 530. Schematic, the first circuit board 521 is mounted on the side of the bracket 530 adjacent to the first receiving cavity 5111. The first circuit board 521 can be connected to the bracket 530 by a suitable method such as adhesive bonding, fastening, or snap-fit ​​connection. The first circuit board 521 is connected to components of the air conditioning unit 200 via cables, thereby enabling the first circuit board 521 to control the operation of the air conditioning unit 200.

[0062] The second circuit board 522 is located within the second receiving cavity 5112 and is configured to control the range hood unit 400. The second circuit board 522 is connected to the other side of the bracket 530. Schematic, the second circuit board 522 is mounted on the side of the bracket 530 adjacent to the second receiving cavity 5112. The second circuit board 522 can be connected to the bracket 530 by a suitable method such as adhesive bonding, fastener securing, or snap-fit ​​connection. The second circuit board 522 is connected to components of the range hood unit 400 via cables, thereby enabling the second circuit board 522 to control the operation of the range hood unit 400.

[0063] The casing 510 has multiple through holes on its wall panel, including at least one first through hole 5121 and at least one second through hole 5122. Those skilled in the art can set the number of each through hole 5121 and through hole 5122 as needed; no single limitation is made here. The first through hole 5121 communicates with the first receiving cavity 5111, and the second through hole 5122 communicates with the second receiving cavity 5112. The first through hole 5121 and the second through hole 5122 are located on different orientations of the casing 510's wall panel. It is understood that the first through hole 5121 is located on the side of the bracket 530 where the first circuit board 521 is located, and the cable between the first circuit board 521 and the components of the air conditioning unit 200 can pass through the casing 510 via the first through hole 5121. The second through hole 5122 is located on the side of the bracket 530 where the second circuit board 522 is located, and the cable between the second circuit board 522 and the components of the range hood unit 400 can pass through the casing 510 via the second through hole 5122.

[0064] The electrical control box 500 provided in this embodiment includes a bracket 530, a first circuit board 521, and a second circuit board 522 installed in a box body 510. The bracket 530 divides the receiving cavity 511 of the box body 510 into a first receiving cavity 5111 and a second receiving cavity 5112. The first circuit board 521 and the second circuit board 522 are located in the two receiving cavities, respectively. A first through hole 5121 and a second through hole 5122 are respectively provided on the wall panels of the box body 510. The first through hole 5121 communicates with the first receiving cavity 5111, and the second through hole 5122 communicates with the second receiving cavity 5112. The first through hole 5121 and the second through hole 5122 are located on the wall panels of the box body 510 facing different directions. The first circuit board 521 can be connected to external wires through the first through hole 5121, and the second circuit board 522 can be connected to external wires through the second through hole 5122. The cables connected to the first circuit board 521 and the cables connected to the second circuit board 522 pass through the wall panels of the box body 510 facing different directions, respectively. This facilitates the wiring and cabling of the electrical control box 500, and consequently, the maintenance of the electrical control box 500.

[0065] In one embodiment, such as Figures 3-5 As shown, there are at least two first through holes 5121, and the at least two first through holes 5121 are located on the wall panels of the box body 510 in different orientations.

[0066] Schematic illustration: The air conditioning unit 200 includes an evaporator, a supply fan, a condenser, a cooling fan, and a compressor. The supply fan draws cooled air from the evaporator into the room. The cooling fan draws indoor air through the condenser and exhausts it outdoors, thus cooling the condenser. The compressor circulates refrigerant between the evaporator and the condenser.

[0067] The first circuit board 521 can be electrically connected to the air supply fan, cooling fan, and compressor via different cables. Furthermore, the first circuit board 521 can also be electrically connected to the water pump, float valve, and oscillating blade motor of the kitchen air conditioner via cables. The cables between the first circuit board 521 and the different components can pass through the corresponding first through holes 5121 on the housing 510.

[0068] With the above configuration, the cables between different components of the air conditioning unit 200 and the first circuit board 521 can pass through different first through holes 5121 according to the wiring distance, which further facilitates the wiring and cabling of the electrical control box 500, and at the same time reduces the total wiring distance in the kitchen air conditioner.

[0069] In a specific embodiment, such as Figure 1 , Figure 3 and Figure 5 As shown, there is one second through hole 5122, and the second through hole 5122 and one of the first through holes 5121 are located on two opposite wall plates of the box body 510.

[0070] Schematic illustration: The interior of the kitchen air conditioner casing 100 is divided into a cold zone and a hot zone by a partition. The evaporator and blower of the air conditioning unit 200 can be arranged in the cold zone, and the condenser and cooling fan of the air conditioning unit 200 can be arranged in the hot zone. The electrical control box 500 can be located in the cold zone. The second through hole 5122 can be located on the side of the electrical control box 500 away from the partition, and one of the first through holes 5121 can be located on the side of the electrical control box 500 adjacent to the partition. The first through hole 5121 and the second through hole 5122 are respectively located on two opposite wall panels of the box body 510. The second circuit board 522 can be electrically connected to the exhaust fan of the range hood unit 400, and the cable between the second circuit board 522 and the exhaust fan can pass through the second through hole 5122 on the box body 510.

[0071] With this structure, during use, the second through hole 5122 of the control box 500 can face the side wall of the kitchen air conditioner, and the first through hole 5121 can face the middle of the kitchen air conditioner, so that the total wiring distance between the different components in the kitchen air conditioner and the circuit board in the control box 500 is minimized.

[0072] like Figures 3-5 As shown, in one specific embodiment, the size of each through hole in the first direction is larger than the size of the through hole in the second direction. The first direction and the second direction are two mutually perpendicular directions on the wall panel where the through hole is located.

[0073] Specifically, the cross-sectional shape of the through hole can be an elongated oval, and the length of the elongated oval can extend along a first direction. Schematic, the first direction can be perpendicular to the thickness direction of the bracket 530, and the second direction can be parallel to the thickness direction of the bracket 530. Understandably, after the cable passes through the corresponding through hole, the position of the cable can be finely adjusted along the first direction.

[0074] With the above setup, the cables between the circuit board and the corresponding components have a certain degree of freedom in the through holes, making it easier for staff to adjust the cable positions.

[0075] In one embodiment, such as Figures 3-6 As shown, each through hole is provided with a sealing element 515. The sealing element 515 is annular and has an opening 5153 for the cable to pass through.

[0076] Schematic illustration: the shape and size of the seal 515 match the corresponding through hole. The seal 515 possesses a certain degree of elasticity; when subjected to external force, the seal 515's opening 5153 opens; when the external force disappears, the opening 5153 closes under the seal 515's own elasticity. After closing, the opening 5153 of the seal 515 effectively prevents water from entering the box 510, thus reducing the risk of water damage to the electrical control box 500.

[0077] In this structure, when no cable is threaded through the through hole, the slit 5153 closes and the seal 515 seals the corresponding through hole; when the slit 5153 is open, a cable can pass through.

[0078] In a specific embodiment, such as Figure 6 As shown, the seal 515 includes an annular wall 5151, which is fitted into the inner edge of the corresponding through hole. It is understood that the annular wall 5151 has an annular structure whose shape and size match the corresponding through hole. Optionally, the annular wall 5151 can be made of an elastic material such as rubber, and the elasticity of the annular wall 5151 achieves a seal between the annular wall 5151 and the corresponding through hole.

[0079] The inner edge of the annular wall 5151 has at least two inwardly extending elastic baffles 5152 in the circumferential direction, and the at least two elastic baffles 5152 are connected to each other to cover the interior of the annular wall 5151. A slit 5153 is defined between the two connected elastic baffles 5152.

[0080] The number of elastic baffles 5152 is not limited, and those skilled in the art can set it as needed. Illustratively, the elastic baffles 5152 can be made of elastic materials such as rubber. The elastic baffles 5152 have a certain degree of elasticity; when an external force is applied to the elastic baffles 5152, they can undergo elastic deformation. When the external force on the elastic baffles 5152 disappears, the elastic baffles 5152 return to their original shape under their own elastic force. Cables between the circuit board and the kitchen air conditioner components can pass between two interconnected elastic baffles 5152.

[0081] In this structure, when the cable has not passed through the inside of the ring wall 5151, the opening 5153 is closed by the interlocking of the elastic baffles 5152; when the cable passes through the inside of the ring wall 5151, the elastic deformation of the elastic baffles 5152 causes the opening 5153 to open so that the cable can pass through.

[0082] like Figures 3-6 As shown, multiple elastic baffles 5152 are respectively provided on opposite sides of the ring wall 5151. The elastic baffles 5152 on both sides of the ring wall 5151 are arranged in a staggered manner and abut against each other.

[0083] Each elastic baffle 5152 may be toothed, and one end of each elastic baffle 5152 may be connected to the inner edge of the ring wall 5151 by bonding or integral molding. Figure 6 As shown, when the cross-sectional shape of the through hole is oblong, multiple elastic baffles 5152 on one side of the through hole can be arranged sequentially along the length of the oblong shape. The shape of the elastic baffles 5152 can be triangular. After the elastic baffles 5152 on both sides of the annular wall 5151 abut against each other, a "wavy" slit 5153 can be formed in the middle of the through hole.

[0084] With the above configuration, when the cable passes through the interior of the annular wall 5151, some of the elastic baffles 5152 can undergo elastic deformation, thereby opening part of the slit 5153 to allow the cable to pass through. The remaining elastic baffles 5152 do not undergo elastic deformation, thus closing the remaining part of the slit 5153, which helps improve the sealing performance of the through hole. In addition, the small area of ​​the elastic baffles 5152 makes it easier for the cable end connector to push against the elastic baffles 5152, causing the elastic baffles 5152 to undergo elastic deformation.

[0085] In one specific implementation, such as Figure 3 , Figure 4 and Figure 6 As shown, a recessed portion 516 is formed on the outer wall of the box 510, and a through hole is formed in the area of ​​the recessed portion 516.

[0086] Understandably, the box body 510 is recessed inward at the recessed portion 516. The depth of the recessed portion 516 can be set as needed and is not limited here. For example, the shape of the recessed portion 516 can match the shape of the through hole. The recessed portion 516 can be formed on the outer wall of the box body 510 by stamping the wall panel of the box body 510. Schematic, the through hole is located at the bottom of the recessed portion 516, that is, the recessed portion 516 is deepest at the location of the through hole.

[0087] With the above configuration, when the seal 515 is installed in the through hole, the recessed portion 516 can reduce the height of the portion of the seal 515 that protrudes from the housing 510, making it less likely for the seal 515 to interfere with the other components of the kitchen air conditioner.

[0088] In one possible implementation, a connecting portion is formed between the side end of the bracket 530 and the corresponding side wall of the box 510, and the connecting portion connects the first receiving cavity 5111 and the second receiving cavity 5112.

[0089] Specifically, at least a portion of the side end of the bracket 530 has a gap between it and the corresponding side wall of the housing 510, which defines a communication portion. Cables between the first circuit board 521 and the second circuit board 522 can pass through the communication portion.

[0090] Specifically, such as Figure 4 As shown, the side end of the bracket 530 is provided with at least two spaced connecting seats 531. The end of the connecting seat 531 abuts against the inner side wall of the box 510, and the interval between two adjacent connecting seats 531 defines a connecting portion.

[0091] The number of connecting seats 531 on one side wall of the bracket 530 can be two, three, or four, etc., and is not limited to a single one. Each connecting seat 531 can be integrally formed on the bracket 530. Understandably, the connecting seat 531 protrudes from the main body of the bracket 530. After the operator places the bracket 530 into the housing 510 of the electrical control box 500, the connecting seats 531 of the bracket 530 can be fixed to the corresponding side wall of the housing 510 by fasteners. When the connecting seat 531 abuts against the side wall of the housing 510, there is a gap between the part of the side end of the bracket 530 located between two adjacent connecting seats 531 and the side wall of the housing 510, thereby defining a communication portion between the side end of the bracket 530 and the side wall of the housing 510.

[0092] With the above arrangement, the bracket 530 abuts against the inner sidewall of the housing 510 via at least two connecting seats 531, thereby forming a communication portion between two adjacent connecting seats 531. In addition, the connecting seats 531 provide a gap between the main body of the bracket 530 and the housing 510, ensuring an electrical clearance between the circuit board on the main body of the bracket 530 and the housing 510.

[0093] like Figure 1 and Figure 2 As shown, 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] Schematic illustration: The housing 100 has a first inner cavity and a second inner cavity arranged vertically. The air conditioning unit 200 and the electrical control box 500 are both installed in the first inner cavity, and the range hood unit 400 is installed in the second inner cavity. The range hood unit 400 includes an exhaust fan disposed in the second inner cavity. The housing 100 also includes a partition disposed in the first inner cavity, which divides the first inner cavity into a cold zone and a hot zone. The electrical control box 500 and the evaporator and air supply fan of the air conditioning unit 200 can be installed in the cold zone, and the condenser and cooling fan of the air conditioning unit 200 can be installed in the hot zone.

[0095] The air supply fan and cooling fan of the air conditioning unit 200 can be electrically connected to the first circuit board 521 of the electrical control box 500 via cables. These cables can pass through the box body 510 of the electrical control box 500 through the first through hole 5121. The exhaust fan of the range hood unit 400 can be electrically connected to the second circuit board 522 of the electrical control box 500 via cables. These cables can pass through the box body 510 of the electrical control box 500 through the second through hole 5122.

[0096] like Figure 1 and Figure 2 As shown, the kitchen air conditioner also includes a fresh air unit 300 installed in the first inner cavity. The fresh air unit 300 can blow fresh outdoor air into the room. The electrical control box 500 can be equipped with a third circuit board. The fresh air unit 300 can be electrically connected to the third circuit board via a cable.

[0097] The kitchen air conditioner provided in this application uses the aforementioned electrical control box 500, which makes wiring and cabling of the electrical control box 500 more convenient, resulting in higher maintenance efficiency for the kitchen air conditioner.

[0098] 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.
