[0002] Among kitchen appliances, cleaning equipment has gradually become an essential household cleaning tool due to its efficient and convenient washing functions. Cleaning equipment operates in a high-temperature and high-humidity environment for extended periods. If the equipment's waterproofing is inadequate, moisture can easily come into contact with internal electronic components, leading to short circuits, component aging, and other malfunctions, severely impacting the normal operation and lifespan of the cleaning equipment. In particular, drawer-type and wall-mounted cleaning equipment have even higher requirements for the waterproofing of their control box components. Currently, drawer-type and wall-mounted cleaning equipment commonly suffer from insufficient door sealing. Frequent door opening and closing easily creates gaps in the sealing structure, allowing moisture to seep in and corrode internal electronic components, leading to frequent malfunctions. To address this issue, existing solutions often use a large amount of foam for sealing. While this method can improve sealing to some extent, it has many drawbacks. Firstly, the procurement and use of foam significantly increases production costs, squeezing profit margins. Secondly, foam has poor water resistance and durability, easily deforming and aging in high-temperature and high-humidity environments, leading to decreased sealing performance and unreliability. This affects product quality, increases after-sales maintenance costs, and reduces consumer satisfaction and trust. The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art.

[0025] Whenever possible, the various aspects and features described and shown in the specification can be applied individually, and these individual aspects can serve as the subject of a divisional application.

[0026] See Figures 1-9 This is one embodiment of a control box assembly for a cleaning device proposed in this utility model. The cleaning device can be a dishwasher, washing machine, or shoe washing machine, etc. In this embodiment, the cleaning device is a dishwasher. See also Figures 1-3 As shown, the cleaning equipment includes: a body 10, a spray arm 20, a return water tank 30, and a door 40. The door 40 has an outer glass 41 and a door liner 43. The space enclosed by the outer glass 41 and the door liner 43 is equipped with a main control board 42 and a control box assembly. One or more control box assemblies can be provided. The control box assembly is equipped with a control board 47. The control board 47 can be a radar module or other modules.

[0027] A control box assembly for a cleaning device includes: a box body 44, a cover 46, a seal 45, and a control board 47. The box body 44 has a slot 448 on its wall. The cover 46 is snapped onto the box body 44. The seal 45 is sealed at the slot 448. The seal 45 has a sealing body 450, a receiving opening 451 for accommodating a wire harness on the sealing body 450, and an expansion rib 452 adjacent to the receiving opening 451. The expansion rib 452 can be easily removed or destroyed. After being removed or destroyed, the expansion rib 452 forms an expansion opening connected to the receiving opening 451.

[0028] In this embodiment, a sealing element 45 is provided at the slot 448 to seal the slot 448, preventing moisture from seeping into the control box and avoiding corrosion of internal electronic components by moisture, thus reducing malfunctions and ensuring a good sealing effect. The expansion ribs 452 on the sealing element 45, when removed or damaged, form an expansion opening connected to the receiving opening 451, allowing the sealing element 45 to be flexibly adjusted according to the actual number and thickness of wire harnesses. Different specifications and quantities of wire harnesses can be adapted by removing or damaging the expansion ribs, improving the versatility and flexibility of the control box assembly and facilitating operation during production and installation. By using the sealing element 45 to achieve waterproof sealing in the control box assembly, the structure of the door 40 is relatively simple, eliminating the need for large-scale procurement and use of foam, thereby reducing raw material costs.

[0029] In some embodiments of this application, a wire-holding groove 453 is provided on the sealing body 450 for installing the wire harness into the receiving port. The wire-holding groove 453 connects the receiving port 451 and the outside of the sealing body 450. When the wire harness is installed into the receiving port 451, it can enter from the outside and pass through the wire-holding groove 453 before reaching the receiving port 451. The sealing body 450 is made of a soft sealing material, such as silicone. The wire-holding groove 453 has two opposing groove walls with a small gap between them, allowing the wire harness to pass through the wire-holding groove 453 through deformation of the two groove walls.

[0030] In some embodiments of this application, the slot 448 is open at one end near the cover 46, and the sealing member 45 is disposed adjacent to the cover 46, with a sealed connection between the sealing member 45 and the cover 46. This sealed connection further ensures the airtightness of the control box, preventing moisture from entering the control box from the connection between the sealing member and the cover, effectively protecting the internal electronic components from moisture corrosion. A wire-holding groove 453 is formed on the side of the sealing member 45 near the cover 46, facilitating the installation or removal of the wire harness through the receiving port 451. When installing the wire harness, it can be easily introduced from the open end through the wire-holding groove 453 into the receiving port 451; when removing the wire harness, this convenient channel can also be used, improving the convenience of wire harness installation and maintenance, and saving time and effort. To facilitate the breaking of the expansion rib 452, the thickness of the expansion rib 452 is less than the thickness of the sealing body 450, and the thickness of the expansion rib 452 is less than the thickness of the receiving port 451. The thickness of the expansion rib 452 is relative to the housing 44 in the inward and outward directions. When it is necessary to enlarge the receiving opening 451 according to the specific situation of the wire harness, the expansion rib 452 can be easily removed or destroyed to form an expansion opening to accommodate wire harnesses of different numbers or thicknesses. This enhances the flexibility and adjustability of the seal, while not causing excessive impact on the main structure of the sealing body 450 and the receiving opening 451, thus ensuring the overall sealing effect and structural strength.

[0031] In some embodiments of this application, a sealing groove 454 matching the edge of the slot 448 is provided on the outer side of the sealing body 450, with the edge of the slot 448 located within the sealing groove 454. The sealing groove 454 fits tightly with the edge of the slot 448, effectively preventing moisture from seeping into the control box from the slot. When the seal 45 is installed at the slot 448, the edge of the slot 448 is embedded in the sealing groove 454, forming a relatively closed space, reducing the channels for moisture to enter, and greatly improving the waterproof performance of the control box. Furthermore, during installation, the seal 45 can be installed more accurately at the slot 448, and the embedding of the edge of the slot 448 into the sealing groove 454 increases the contact area and friction between the two, making the seal 45 more stable at the slot 448, less prone to displacement or loosening, and contributing to increased stability after installation.

[0032] In some embodiments of this application, a plurality of control claws 445 for engaging the control board 47 are provided inside the housing 44, and the control claws 445 extend toward the cover 46. Since the control claws 445 extend toward the cover 46, when installing the control board 47, it is only necessary to place and engage the control board 47 along the direction of the control claws 445. The multiple control claws 445 can engage and fix the control board 47 from different positions, effectively preventing the control board 47 from shaking, shifting, or falling out within the housing 44.

[0033] In some embodiments of this application, a front guide rib 443 and a rear guide rib 444 are provided inside the housing 46 for guiding the installation of the control board 47. The control claws are located in the left-right direction of the control board. The front guide rib 443 is inclined away from the control board 47 in the direction near the housing cover 46. The rear guide rib 444 is inclined away from the control board 47 in the direction near the housing cover 46. The front guide rib 443 and the rear guide rib 444 provide a guiding path for the installation of the control board 47. The installer does not need to repeatedly adjust the alignment; he only needs to push the control board 47 into the housing 44 along the inclined direction of the guide ribs to quickly position the control board 47 in the correct position. This reduces the installation difficulty and improves production assembly efficiency. The guide ribs and the control claws 454 form a three-dimensional fixing structure. While the control claws 454 engage the control board 47 from the left and right directions, the front and rear guide ribs can restrict the movement of the control board 47 in the front-back direction, preventing the control board 47 from shaking back and forth inside the housing 44.

[0034] In some embodiments of this application, a disassembly structure for removing the cover 46 is provided between the box body 44 and the cover 46. The disassembly structure has a second protruding rib 442 on the box body 44 and a first protruding rib 461 on the cover 46. The first protruding rib 461 extends outward along the cover 46, and the second protruding rib 442 extends outward along the box body 44. The first protruding rib 461 and the second protruding rib 442 are matched, forming a disassembly space between them that allows maintenance tools to be inserted. The matching first protruding rib 461 and the second protruding rib 442, and the resulting disassembly space for maintenance tools, allow maintenance personnel to easily insert tools (such as screwdrivers, pry bars, etc.) into this space when it is necessary to remove the cover 46, and easily separate the cover 46 from the box body 44 using leverage or other methods. The matching first and second protruding ribs, in addition to facilitating disassembly when the cover is installed on the box body, also allow the operator to quickly identify the front and back orientation of the cover 46.

[0035] In some embodiments of this application, a first engaging structure is provided between the housing 44 and the cover 46. The first engaging structure has a first latch 463 on the cover 46 and a retaining rib 447 on the housing 44, with the retaining rib 447 matching the first latch 463. The first latch 463 extends into the housing 44. This design ensures a secure mechanical connection between the cover 44 and the housing 46. The stable engaging connection helps maintain a tight seal between the housing 44 and the cover 46. When installing the cover 46, simply align the first latch 463 with the retaining rib 447 and press gently to complete the engagement. The operation is simple and intuitive, reducing installation difficulty and time costs. The design of the first latch 463 extending into the housing 44 for engagement fully utilizes the internal space of the housing 44, eliminating the need for additional connecting parts or structures on the outside of the housing 44, making the overall structure of the control box assembly more compact.

[0036] In some other embodiments of this application, the first engaging structure may also have a first claw provided on the box body 44 and a rib provided on the cover body 46.

[0037] In some embodiments of this application, a second engaging structure is provided between the box body 44 and the cover 46. The second engaging structure has a latching protrusion 446 on the box body 44 and a latching plate 462 on the cover 46. The latching plate 462 has a latching hole that matches the latching protrusion 446. The second engaging structure complements the first engaging structure, providing a secure connection between the box body 44 and the cover 46 by embedding the latching protrusion 446 into the latching hole. This double engaging design effectively disperses vibrations and external forces generated during dishwasher operation, further preventing the cover 46 from loosening or falling off, and ensuring the control box's sealing. The matching of the latching protrusion 446 and the latching hole provides precise positioning when installing the cover 46.

[0038] In some embodiments of this application, the box body 44 is provided with a limiting plate 441 for preventing the card plate 462 from disengaging after engagement. A receiving space for accommodating the card plate 462 is formed between the limiting plate 441 and the setting surface 449 of the card protrusion 446. The card plate 462 is arranged parallel to the setting surface 449. The receiving space formed by the limiting plate 441 and the setting surface 449 precisely confines the card plate 462 within it, preventing it from moving or disengaging freely after engagement, thus ensuring the stability of the connection between the cover 46 and the box body 44. The card plate 462 is stably confined within the receiving space, ensuring a uniform and durable seal between the cover 46 and the box body 44.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
