However, liquids outside the control box can easily seep into the box body through the fastening holes, causing damage to the control box. Utility Model Content

[0004] Based on this, this application provides an electrical control box and a kitchen air conditioner to solve the problem in the related art that liquid outside the electrical control box can easily seep into the inside of the box through the fastening holes on the box body, causing damage to the electrical control box.

[0005] In a first aspect, this application provides an electrical control box applied to a kitchen air conditioner, the kitchen air conditioner including a range hood unit and an air conditioning unit, the signal terminal of the electrical control box being used to control the range hood unit and the air conditioning unit; the electrical control box includes:

[0006] The box body has a first fastening hole on at least one side wall;

[0007] The bracket is installed inside the box, and a second fastening hole is provided on the end side of the bracket, which is opposite to the first fastening hole;

[0008] Fastener, passing through the first fastening hole and locked into the second fastening hole;

[0009] The bracket also has a sealing surface on its end side, which surrounds the second fastening hole. When the bracket and the box are assembled, the sealing surface is in close contact with the side wall of the box.

[0010] In one possible implementation, a protrusion is provided on the inner sidewall of the box, the protrusion protrudes into the inside of the box, the protrusion abuts against the end side of the bracket, and the first fastening hole is located at the center of the protrusion.

[0011] With this structure, the box body abuts against the end side of the bracket through the protrusion, and the sealing surface can fit more tightly with the side wall of the box body, further improving the sealing performance between the box body and the bracket.

[0012] In one possible implementation, a groove is provided on the end side of the bracket, a protrusion extends into the groove and abuts against the bottom of the groove, the protrusion is slidably connected to the groove, and a second fastening hole is provided at the bottom of the groove.

[0013] The sealing surface is the bottom surface of the groove.

[0014] In this structure, the bracket can be guided by the cooperation between the protrusion and the slide groove during the installation process. In addition, the side wall of the slide groove can also abut against the side wall of the protrusion, increasing the sealing between the bracket and the box.

[0015] In one possible implementation, the slide has a first end and a second end that are disposed opposite to each other in the extending direction, and the protrusion is capable of sliding relative to the slide along the extending direction of the slide.

[0016] The first end is provided with an opening for the protrusion to slide into;

[0017] When the bracket and the box are assembled, the second end abuts against the protrusion.

[0018] This structure allows the bracket to be positioned by the engagement between the second end of the slide and the protrusion, making it easy for workers to align the first fastening hole of the box with the second fastening hole of the bracket so that fasteners can be used to fix the bracket to the box.

[0019] In one possible implementation, the wall thickness of the sidewall of the box in the region forming the protrusion is the same as the wall thickness in the rest of the region.

[0020] This structure allows protrusions to be formed on the box body by stamping, making it easy to install protrusions on the box body.

[0021] In one possible implementation, a connecting seat is provided on the end side of the bracket, and a sliding groove is provided at one end of the connecting seat near the side wall of the box.

[0022] In this structure, the connecting seat of the bracket can ensure a safe clearance between the main body of the bracket and the side wall of the box, thereby ensuring a safe clearance between the electronic components on the main body of the bracket and the side wall of the box.

[0023] In one possible implementation, the two opposite ends of the bracket abut against the two inner sidewalls of the box body, respectively.

[0024] This structure allows the support frame to support the two opposite side walls of the box, making the box less prone to deformation.

[0025] In one possible implementation, the support includes a frame and a connecting edge, the connecting edge extending parallel to the sidewalls adjacent to the box and the frame, and the connecting edge surrounding the outer edge of the frame;

[0026] The connecting edges on the two opposite ends of the bracket abut against the inner sidewalls of the box.

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

[0028] In one possible implementation, the control box further includes a first circuit board and a second circuit board, the first circuit board being configured to control the air conditioning unit and the second circuit board being configured to control the range hood unit, the first circuit board and the second circuit board being respectively mounted on opposite sides of the bracket.

[0029] In this structure, the first circuit board and the second circuit board are respectively installed on opposite sides of the bracket, which can reduce the space occupied by the first circuit board and the second circuit board inside the box, thus helping to reduce the size of the electrical control box.

[0030] 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, and the range hood unit and air conditioning unit are electrically connected to the electrical control box respectively.

[0031] The electrical control box and kitchen air conditioner provided in this application include a box body, a bracket, and fasteners. A first fastening hole is provided on at least one side wall of the box body, and a second fastening hole is provided on one end of the bracket, opposite to the first fastening hole. Simultaneously, the end of the bracket also has a sealing surface surrounding the second fastening hole. In the assembled state, the sealing surface is tightly fitted against the side wall of the box body. The bracket can be installed inside the box body through the first fastening hole, the second fastening hole, and the fasteners. When liquid from outside the electrical control box flows into the first fastening hole, because the sealing surface of the bracket is tightly fitted against the side wall of the box body, the liquid will not flow from the first fastening hole into other areas inside the box body besides the bracket, thus preventing damage to the electronic components inside the box body.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] In existing technology, kitchen air conditioners control the operation of the range hood unit and the air conditioning unit through a control box, and the components inside the control box are fastened to the box body with fasteners. However, liquids outside the control box can easily seep into the box body through the fastening holes on the box body, causing damage to the control box.

[0056] After repeated consideration and verification, the inventors discovered that if a first fastening hole is provided on the body of the electrical control box, a bracket is provided inside the box, a second fastening hole is provided on the bracket opposite to the first fastening hole, and a sealing surface surrounding the second fastening hole is provided on a component inside the box, and a fastener is passed through the first fastening hole and locked into the second fastening hole, the sealing surface will be tightly attached to the wall of the box. Because the sealing surface of the bracket is tightly attached to the wall of the box, the airtightness between the box and the bracket is ensured, preventing liquid from the outside of the box from flowing into the rest of the box except for the bracket through the first fastening hole, thus preventing water ingress damage to the electrical control box.

[0057] In view of this, the inventor designed an electrical control box and a kitchen air conditioner. By setting a first fastening hole on the box body and a second fastening hole and a sealing surface surrounding the second fastening hole on the bracket of the electrical control box, after the box body and the bracket are locked together by fasteners through the first fastening hole and the second fastening hole, the sealing surface of the bracket is pressed tightly against the wall of the box body, preventing liquid outside the electrical control box from entering the box body through the first fastening hole and the gap between the bracket and the box body, which would cause damage to the electronic components inside the box body.

[0058] 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.

[0059] Reference Figures 1 to 8 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.

[0060] To illustrate, the kitchen air conditioner also includes a housing 100, an electrical control box 500, a range hood unit 400, and an air conditioning unit 200, all installed inside the housing 100. The electrical control box 500 is electrically connected to both the range hood unit 400 and the air conditioning unit 200, allowing the signal terminal of the electrical control box 500 to control the operation of both units. It is worth noting that the air conditioning unit 200 produces condensate during operation, which may flow onto the electrical control box 500.

[0061] The electrical control box 500 includes a box body 510, a bracket 530, and fasteners. At least one side wall of the box body 510 has a first fastening hole 5125. (The rest of the text appears to be unrelated and possibly machine-generated.) Figure 4As shown, the box body 510 includes a box portion 512 and a first cover 513 covering the box portion 512. The box portion 512 has a receiving cavity and a first opening communicating with the receiving cavity. The first cover 513 can close the first opening of the box portion 512. The side wall of the box body 510 is the wall surface of the box portion 512 surrounding the first opening, and a first fastening hole 5125 is provided through the side wall of the box body 510. The number of first fastening holes 5125 can be one or more, and is not limited here.

[0062] The bracket 530 is installed inside the housing 510, and a second fastening hole 537 corresponding to the first fastening hole 5125 is provided on the end side of the bracket 530. The bracket 530 can accommodate electronic components inside the housing 510, such as circuit boards or capacitors. Specifically, the bracket 530 is installed within the receiving cavity. The second fastening hole 537 is coaxially arranged with the first fastening hole 5125, and the second fastening hole 537 is an internally threaded hole. The number of second fastening holes 537 is the same as the number of first fastening holes 5125, with each second fastening hole 537 corresponding to one first fastening hole 5125. It should be noted that the second fastening hole 537 does not penetrate the bracket 530; that is, the second fastening hole 537 is a blind hole located on the end side of the bracket 530. The above arrangement ensures that after liquid outside the housing 510 flows into the second fastening hole 537 through the first fastening hole 5125, it will not flow into the interior of the housing 510 except for the bracket 530.

[0063] The fastener passes through the first fastening hole 5125 and is locked in the second fastening hole 537. A screw can be used as the fastener, with the screw threaded into the second fastening hole 537 after passing through the first fastening hole 5125. The head of the fastener abuts against the outer wall of the housing 510.

[0064] The bracket 530 also has a sealing surface 5361 on its end side, which surrounds the second fastening hole 537. When the bracket 530 and the housing 510 are assembled, the sealing surface 5361 is in close contact with the side wall of the housing 510. It is worth noting that the portion of the sealing surface 5361 that is in close contact with the housing 510 also surrounds the second fastening hole 537. Therefore, when liquid from outside the housing 510 enters the housing 510 through the first fastening hole 5125, the liquid will not pass between the sealing surface 5361 and the side wall of the housing 510 and enter the area inside the housing 510 other than the bracket 530.

[0065] In one possible implementation, the bracket 530 may have a sealing layer on the sealing surface 5361. For example, the bracket 530 may have an elastic rubber layer on the sealing surface 5361. The bracket 530 is pressed against the side wall of the box 510 through the rubber layer, which can further improve the sealing between the bracket 530 and the box 510.

[0066] Optionally, a sealing ring may also be provided on the bracket 530, which surrounds the second fastening hole 537. The sealing ring can be pressed against the portion of the box 510 located outside the first fastening hole 5125 to improve the sealing between the bracket 530 and the box 510.

[0067] The electrical control box 500 provided in this embodiment allows the bracket 530 to be installed inside the box body 510 via the first fastening hole 5125, the second fastening hole 537, and fasteners. When liquid from outside the electrical control box 500 flows into the first fastening hole 5125, the liquid will not flow from the first fastening hole 5125 into other areas inside the box body 510 except for the bracket 530 because the sealing surface 5361 of the bracket 530 is in close contact with the side wall of the box body 510, thus preventing damage to the electronic components inside the box body 510.

[0068] In one embodiment, such as Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, a protrusion 5126 is provided on the inner sidewall of the box 510, and the protrusion 5126 protrudes into the interior of the box 510. For example, a frustum is provided on the inner sidewall of the box 510. The height and area of ​​the protrusion 5126 can be set as needed and are not limited here.

[0069] The protrusion 5126 abuts against the end side of the bracket 530, and the first fastening hole 5125 is located at the center of the protrusion 5126. The end face of the protrusion 5126 facing the interior of the housing 510 can be a flat surface, which can fit tightly against the end side of the bracket 530. The sealing surface 5361 of the bracket 530 can be either a flat surface or a conical surface. When the sealing surface 5361 is flat, it fits tightly against the end face of the protrusion 5126 facing the interior of the housing 510; when the sealing surface 5361 is conical, it matches the sidewall of the protrusion 5126, and the sealing surface 5361 fits tightly against the sidewall of the protrusion 5126.

[0070] Understandably, a protrusion 5126 is provided on the inner side wall of the box body 510. The side wall of the box body 510 is closer to the bracket 530 at the position of the protrusion 5126 than at other positions. The box body 510 abuts against the end side of the bracket 530 through the protrusion 5126, and the sealing surface 5361 can fit more tightly with the side wall of the box body 510, further improving the sealing performance between the box body 510 and the bracket 530.

[0071] In a specific embodiment, such as Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, a groove 536 is provided on the end side of the bracket 530. Schematic, the box portion 512 has a bottom wall away from the first opening, and the extension direction of the groove 536 can be parallel to the direction from the first opening to the bottom wall. The groove 536 can be integrally formed on the end side of the bracket 530.

[0072] The protrusion 5126 extends into the groove 536 and abuts against the bottom of the groove 536. The protrusion 5126 is slidably connected to the groove 536, and the second fastening hole 537 is provided at the bottom of the groove 536. After the protrusion 5126 slides relative to the groove 536 to a position where the first fastening hole 5125 and the second fastening hole 537 are opposite, a fastener can be used to pass through the first fastening hole 5125 and lock it in place with the second fastening hole 537. The sealing surface 5361 is the bottom surface of the groove 536. In the width direction of the groove 536, the second fastening hole 537 can be located in the middle of the bottom of the groove 536.

[0073] In this structure, during the insertion of the bracket 530 into the housing 510, the engagement of the protrusion 5126 and the groove 536 guides the bracket 530. The bottom surface of the groove 536 abuts against the end of the protrusion 5126 facing inwards from the housing 510, achieving a seal between the bracket 530 and the housing 510. Furthermore, the sidewall of the groove 536 can also abut against the sidewall of the protrusion 5126, further enhancing the seal between the bracket 530 and the housing 510.

[0074] In one specific implementation, such as Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the slide groove 536 has a first end and a second end that are oppositely disposed in the extending direction, and the protrusion 5126 can slide relative to the slide groove 536 along the extending direction of the slide groove 536. The first end is provided with an opening for the protrusion 5126 to slide into. The first end of the slide groove 536 is the open end of the slide groove 536, and the second end of the slide groove 536 is the closed end of the slide groove 536. During the assembly of the bracket 530, the protrusion 5126 can slide from the first end (open end) of the slide groove 536 into the interior of the slide groove 536. As the bracket 530 moves, the protrusion 5126 can slide along the extending direction of the slide groove 536 within the slide groove 536.

[0075] When the bracket 530 and the housing 510 are assembled, the second end abuts against the protrusion 5126. Specifically, after the second end of the slide groove 536, i.e. the closed end, abuts against each other, the protrusion slides relative to the slide groove 536 to the position where the first fastening hole 5125 and the second fastening hole 537 are opposite. At this time, fasteners can be used to lock the bracket 530 and the housing 510.

[0076] The bracket 530 can be limited by the cooperation between the second end of the slide groove 536 and the protrusion 5126, so that the staff can align the first fastening hole 5125 of the box body 510 with the second fastening hole 537 of the bracket 530, so as to use fasteners to fix the bracket 530 to the box body 510.

[0077] In one possible implementation, such as Figure 7 and Figure 8 As shown, the wall thickness of the sidewall of the box 510 in the area where the protrusion 5126 is formed is the same as the wall thickness in the rest of the area.

[0078] Specifically, a protrusion 5126 can be formed on the side wall of the box body 510 by stamping, and a recess is formed on the outer side of the box body 510 in the area where the protrusion 5126 is provided. The above arrangement facilitates the placement of the protrusion 5126 on the side wall of the box body 510.

[0079] In other embodiments, the protrusion 5126 can also be formed by installing a protrusion on the inner sidewall of the housing 510. The protrusion can be fixed to the side plate of the housing 510 by means of bonding or welding. The above arrangement is equivalent to the wall thickness of the housing 510 at the location of the protrusion 5126 being greater than the wall thickness at other locations.

[0080] In one possible implementation, such as Figures 4-6 As shown, a connecting seat 538 is provided on the end side of the bracket 530. The connecting seat 538 protrudes from the main body of the bracket 530 on its end side, and the end of the connecting seat 538 adjacent to the side wall of the box 510 can abut against the corresponding side wall of the box 510. The connecting seat 538 can be integrally formed onto the bracket 530. The number of connecting seats 538 can be one or more, and is not limited here. This embodiment does not limit the height of the connecting seat 538; those skilled in the art can set it as needed.

[0081] A slide groove 536 is provided at one end of the side wall of the connecting seat 538 adjacent to the box body 510. Optionally, each connecting seat 538 is provided with a slide groove 536 at one end of the side wall adjacent to the box body 510.

[0082] In this embodiment, the connecting seat 538 of the bracket 530 can ensure a safe gap between the main body of the bracket 530 and the side wall of the box 510, and prevent the main body of the bracket 530 from abutting against the side wall of the box 510, thereby ensuring a safe gap between the electronic components on the main body of the bracket 530 and the side wall of the box 510.

[0083] For example, the two opposite ends of the bracket 530 abut against the two inner sidewalls of the box 510 respectively.

[0084] For example, stent 530 inFigure 4 The top side of the middle and the box 510 are in Figure 4 The inner walls of the upper middle section abut against each other, and the bracket 530 is in Figure 4 The bottom side of the middle and the box body 510 are in Figure 4 The inner sidewalls at the lower center abut each other. The two opposite ends of the bracket 530 can each be provided with a second fastening hole 537, and correspondingly, the two opposite sidewalls of the box body 510 can each be provided with a first fastening hole 5125. The two opposite ends of the bracket 530 can be locked to the two opposite sidewalls of the box body 510 by fasteners.

[0085] In this embodiment, the bracket 530 can support the two opposite side walls of the box 510, making the box 510 less prone to deformation, thereby ensuring the reliability of the electrical control box 500.

[0086] like Figures 4-6 As shown, the bracket 530 includes a frame 531 and a connecting edge 532. The extending direction of the connecting edge 532 is parallel to the side wall of the box 510 adjacent to the frame 531. The connecting edge 532 is arranged around the outer edge of the frame 531.

[0087] Schematic illustration: The frame 531 can be a plate-like structure, and the extension direction of the connecting edge 532 can be perpendicular to the extension direction of the plate-like structure. For example, the connecting edge 532 can be integrally formed onto the frame 531, or it can be formed on the outer edge of the frame 531 by bending the edge of the frame 531. The width of the connecting edge 532 can be set as needed and is not limited here.

[0088] The connecting edges 532 on the two opposite ends of the bracket 530 abut against the inner sidewalls of the box 510. Schematic, after the bracket 531 is placed inside the box 510, the side of the connecting edge 532 facing the sidewall of the box 510 abuts against the sidewall of the box 510. When the bracket 531 and the box 510 are secured with fasteners, the connecting edge 532 is tightly pressed against the inner sidewall of the box 510.

[0089] Through the above settings, the connecting edge 532 of the frame 531 ensures the contact area between the end side of the bracket 530 and the box 510, ensuring the support effect of the bracket 530 on the box 510, and further improving the reliability of the electrical control box 500.

[0090] In one embodiment, such as Figure 3 and Figure 7 As shown, the electrical control box 500 also includes a first circuit board 521 and a second circuit board 522. 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. The first circuit board 521 and the second circuit board 522 are respectively mounted on opposite sides of the bracket 530.

[0091] Schematic illustration: The 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 via cables to control their operation, thereby controlling the air conditioning unit 200. The range 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, thereby controlling the range hood unit 400.
