Description

Technical Field

[0001] This application relates to the technical field of disinfection cabinets, specifically to the technical field of an easy-to-maintain double-door disinfection cabinet. Background Technology

[0002] Currently, double-door disinfection cabinets are widely used in collective kitchen environments such as schools, factories, and enterprises for high-temperature or ultraviolet disinfection of tableware. However, these locations typically involve frequent operations and are characterized by humid and greasy environments, resulting in the equipment operating under high load and high pollution conditions for extended periods.

[0003] However, existing double-door disinfection cabinets generally suffer from complex structures, easily aging door seals, and narrow cleaning channels, making daily maintenance and deep cleaning extremely difficult. Maintenance is particularly inconvenient when dealing with the door seals, the cleanliness of the inner liner, and the maintenance of components (heating elements, UV lamps, fans, etc.).

[0004] Therefore, there is an urgent need to design a double-door disinfection cabinet that is simple in structure, easy to assemble and disassemble, easy to clean and convenient to maintain, in order to meet the actual needs of complex usage environments such as collective kitchens. Summary of the Invention

[0005] This application proposes an easy-to-maintain double-door disinfection cabinet. Through the reasonable layout of the double-door disinfection cabinet, the convenience of maintenance can be improved while ensuring the disinfection effect.

[0006] To achieve the above objectives, the present application adopts the following technical solution: This application proposes an easy-to-maintain double-door disinfection cabinet, including: an upper keel assembly, a lower keel assembly, and front ribs, rear ribs, and side ribs respectively connected between the upper keel assembly and the lower keel assembly to form an inner cavity; It also includes a surrounding panel surrounding the outer side of the inner cavity and a door body located at the front end of the inner cavity, with an upper bushing and a lower bushing respectively provided on the outer sides of the upper and lower ends of the door body; The front end of the lower keel assembly is provided with a support part that can support the door in the closed state.

[0007] Thus, by setting up upper and lower keel components, and connecting them with front, rear, and side ribs to form an open internal cavity skeleton structure, the splicing gaps and hard-to-clean corners of traditional closed inner liner are effectively reduced, facilitating cleaning. Simultaneously, the door body is rotatably connected to the keel components via upper and lower outer bushings, working in conjunction with the front support to achieve stable opening and closing while preventing the rotating structure from being inside the cavity. This facilitates maintenance and prevents contamination, resulting in a simple, highly modular overall structure that improves maintainability and reliability in humid and oily environments.

[0008] In some possible implementations, the front end of the upper keel assembly is provided with a sensor head that can sense the opening and closing status of the door.

[0009] In some possible implementations, the upper keel assembly includes a central upper crossbeam and a front upper crossbeam forming a T-shaped keel structure, and the lower keel assembly includes a central support beam, a front support beam, and a rear support beam forming an I-shaped keel structure.

[0010] In some possible implementations, the lower end of the upper keel assembly is provided with a support plate, and the support plate is provided with an air intake and a fan.

[0011] In some possible implementations, the upper end of the upper keel assembly is provided with a top plate, and an air outlet channel is formed between the top plate and the support plate and connected to the air outlet.

[0012] In some possible implementations, the air outlet duct is provided with a first reinforcing rib and a second reinforcing rib.

[0013] In some possible implementations, a heating tube is provided at the bottom of the inner cavity and an ultraviolet lamp is provided at the top.

[0014] In some possible implementations, a first air inlet is provided at the bottom of the inner cavity, and a second air inlet is provided behind the ultraviolet lamp.

[0015] In some possible implementations, the bottom of the support is provided with sliding wheels for supporting the door.

[0016] In some possible implementations, a basket is also included that is attached to the side and rear ribs by means of snap-fit. Attached Figure Description

Detailed Implementation

[0018] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art: It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0019] Furthermore, 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, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0020] Please refer to Figure 1 The present application provides an easy-to-maintain double-door disinfection cabinet, the overall appearance structure of which includes a surrounding panel 100 and a door 200, presenting a simple and complete appearance when the door 200 is closed. Figure 2 This is a diagram showing the state of the door 200 after it is opened. The entire internal structure is fully unfolded, making it convenient for users to put away tableware or perform maintenance and cleaning.

[0021] First, the overall structure of the disinfection cabinet will be explained. Please refer to [link / reference]. Figure 2 , Figure 5 and Figure 7 The disinfection cabinet of this application has an upper keel assembly and a lower keel assembly. The upper keel assembly is located at the top of the cabinet and includes a central upper crossbeam 111 arranged longitudinally in the center and a front upper crossbeam 112 located in front of it, which together form a T-shaped keel structure. A top plate 110 is provided on top of the upper keel assembly. The lower keel assembly is located at the bottom and consists of a central support beam 151, a front support beam 152, and a rear support beam 153 forming an I-shaped keel structure, which is fixedly connected to the bottom plate 150, forming a highly stable load-bearing platform that effectively resists the risk of deformation during long-term use.

[0022] Please refer to the reference. Figure 4 The front rib 101, rear rib 131, and side rib 141, connecting the upper and lower keel components, extend vertically to enclose an open inner cavity frame. Preferably, one front rib 101 is used, positioned in the middle of the closed door 200. Three rear ribs 131 can be used, evenly distributed in the middle and on both sides. The number of side ribs 141 can be flexibly set; in this embodiment, two are used. When the disinfection cabinet is designed to be thinner, one side rib 141 can be used.

[0023] Please refer to the reference. Figure 4 and Figure 6The tableware is placed in the inner cavity through the mesh basket 10. The two sides of the mesh basket 10 adopt a snap-on structure, which can be quickly hung on the side ribs 141 and the rear ribs 131, making it easy to disassemble for cleaning or to replace different sizes. In addition, the mesh basket itself has no welding dead corners, further improving its hygiene performance.

[0024] Thus, compared to traditional enclosed inner liner, this frame significantly reduces splicing gaps and hidden corners, preventing oil and scale from accumulating in dead corners and significantly improving cleaning efficiency. It is especially suitable for collective kitchen environments with heavy oil fumes and high humidity, such as schools and factories.

[0025] Further, please refer to Figure 5 The outer enclosure 100 will be described below. The enclosure 100 surrounding the frame is not a single piece, but rather consists of a top plate 110, a rear enclosure 130, and side enclosures 140 on both sides. Each panel of the enclosure 100 is detachably installed to its corresponding frame position using clips or screws. This allows for quick access to the fault area by removing only a portion of the enclosure when internal components need repair, without requiring complete disassembly of the entire machine, significantly reducing maintenance barriers and time costs.

[0026] For door size 200, please refer to the following: Figure 2 and Figure 3 The door 200 is a double-opening structure located at the front end of the inner cavity. An upper bushing 211 and a lower bushing 212 are respectively provided on the outer sides of its upper and lower ends. The upper bushing 211 is fixedly connected to the upper keel assembly, and the lower bushing 212 is fixedly connected to the lower keel assembly, allowing the door 200 to rotate smoothly relative to the bushings around a vertical axis. Simultaneously, a support portion 213 is provided at the front end of the lower keel assembly, providing support to its bottom when the door 200 is closed, reducing stress on the door seal and delaying the aging of the sealing strip. A sliding wheel 2131 is also integrated at the end of the support portion 213 to reduce friction when the door 200 is opened and closed.

[0027] In this way, the door body 200 is rotatably connected to the keel assembly through the outer upper bushing 211 and lower bushing 212, and together with the front support part 213, it can achieve stable opening and closing and avoid the rotating structure in the inner cavity, which is convenient for maintenance and prevents pollution. This makes the overall structure simple and highly modular, and improves the ease of maintenance and reliability in humid and greasy environments.

[0028] Furthermore, the front end of the upper keel assembly is equipped with a sensor head 214 for real-time detection of the opening and closing status of the door 200, which can be used to implement a safety protection mechanism of power-off when the door is opened through a linkage control system. Control systems are commonly used devices and systems in disinfection cabinets and other home appliances, and will not be described in detail here.

[0029] The following explains the configuration of the functional devices in the disinfection cabinet. Please refer to the following instructions. Figure 4The disinfection function is achieved through the coordinated operation of the heating tube 20 at the bottom of the inner cavity and the ultraviolet lamp 30 at the top. For details regarding the airflow channel design for disinfection, please refer to [link / reference needed]. Figures 5 to 7 The lower end of the upper keel assembly is provided with a support plate 120, on which the fan 40 is installed, and an air intake 41 is provided on the air inlet side. A closed air outlet channel is formed between the support plate 120 and the upper top plate 110, and the rear side of this channel is connected to the air outlet 53, so that hot and humid air can be efficiently discharged. To further enhance the strength of the channel and optimize the airflow, a first reinforcing rib 121 and a second reinforcing rib 122 are provided in the air outlet channel, which have both structural support and air guiding functions. That is, the first reinforcing rib 121 is a figure-eight design with an opening facing the air outlet 53.

[0030] Furthermore, regarding air intake, a first air inlet 51 is provided on the base plate 150, and a second air inlet 52 is provided on the rear panel behind the ultraviolet lamp tube 30. Cold air enters through these inlets, rises after being heated or irradiated by ultraviolet light, and is finally discharged through the air outlet 53, forming a forced convection from bottom to top, which improves the uniformity and efficiency of disinfection. In particular, the cold air from the second air inlet 52 can dilute the heated air, preventing it from being discharged at a high temperature.

[0031] As stated above, this case protects an easy-to-maintain double-door disinfection cabinet, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
