Description

Technical Field

[0001] The utility model relates to a disinfection device, in particular to a disinfection cabinet. Background Art

[0002] Now as residents become more aware of their health, disinfection cabinets are consumed more and more frequently in the market. As a device that can be used to disinfect commonly used objects (bowls, chopsticks, etc.) at home, its core components (such as heating devices and disinfection devices) often generate heat and accumulate dust during use, so they need to be protected.

[0003] To address this issue, a Chinese utility model patent in the prior art with patent application number CN202122097503.3 (publication number CN215961303U) titled "Y-type catering table-disinfection cabinet" discloses a disinfection cabinet with a protective structure for the heating component and the disinfection component and a removable baffle.

[0004] Similarly, the Chinese utility model patent "A large multifunctional disinfection cabinet" with patent application number CN202122538104.6 (publication number CN215961262U) discloses a protective tube arranged outside the ultraviolet lamp, which not only protects the ultraviolet lamp, but also serves as a circulation pipe for ozone and high-temperature gas. There is also a baffle on the side of the cabinet that can be slid open and closed.

[0005] The above-mentioned disinfection cabinet protects the heating component and the disinfection component by providing a protective cover, and the detachable connection mode of the baffle provides convenience for the maintenance of the disinfection cabinet. However, the disinfection cabinet increases its own materials while realizing the protection function of the heating component (providing additional protection structure and installation structure), which increases the strength requirements of the bottom support structure. Therefore, the bottom of the disinfection cabinet adopts a base of a whole thick plate or a two-layer support structure, which increases the production cost and weight, and is relatively expensive and bulky. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a disinfection cabinet with a low heating component setting cost in view of the above-mentioned existing technical status.

[0007] The utility model solves the above technical problems by adopting the following technical solution: the disinfection cabinet comprises a cabinet body and a heating device, the cabinet body comprises a top plate, a rear plate and side plates located on both sides of the rear plate, the top plate, the rear plate and the side plates enclose a disinfection cavity, the heating device is arranged at the bottom of the disinfection cavity, and is characterized in that:

[0008] The lower end of the cabinet is bent inward to form a first bent portion, and the orthographic projection of the heating device is on the first bent portion.

[0009] In order to enable the heating device to work in a fixed position and the overall airtightness of the disinfection cabinet, from the perspective of simple structure, preferably, the cabinet has a door frame at the front end, the rear end of the mounting plate is arranged above the first bending portion, the front end is connected to the door frame, and the heating device is arranged on the upper surface of the mounting plate. The connection between the mounting plate and the cabinet seals the bottom of the disinfection cavity, and the heating device is fixed to the mounting plate so that the relative position of the heating device and the cabinet remains unchanged when the disinfection cabinet is moved.

[0010] In order to make the disinfection cabinet meet safety regulations, preferably, the first bending portion includes a main body and a vertical plate extending vertically upward from the front end of the main body. This design reduces the distance between the first bending portion and the mounting plate.

[0011] In order to further reduce the distance between the first bent portion and the mounting plate, preferably, an inclined plate is extended from the middle of the vertical plate, and the upper end of the inclined plate is against or close to the bottom surface of the mounting plate. In this technical solution, the inclined plate reduces the distance between the first bent portion and the mounting plate and covers the bottom of the heating device, so that the first bent portion has a protective effect on the heating device, which has the advantage of "one object with two uses".

[0012] In order to allow sufficient installation space for the heating device, preferably, the upper end surface of the installation plate is concave to form a groove, and the heating device is limited in the groove. This technical solution increases the installation depth of the heating device.

[0013] Furthermore, the upper end surface of the mounting plate has the groove, so that the bottom surface of the mounting plate bulges downward to form a protrusion, and the inclined plate abuts against or is close to the protrusion. This technical solution makes the inclined plate closer to or even abuts against the bottom surface of the mounting plate, which is conducive to passing the safety inspection.

[0014] In order to ensure that the disinfection cabinet can be placed stably, preferably, the door frame is bent inward to form a second bent portion, and the front end of the mounting plate is placed on the second bent portion. In this technical solution, the supporting structure connecting the front and rear ends of the mounting plate is firm, and the mounting plate can be placed horizontally and stably relative to the cabinet body.

[0015] In order to achieve normal operation of the heating device, preferably, the heating device includes:

[0016] Two supports are arranged on the mounting plate at intervals;

[0017] A heating element, which is strip-shaped and has two ends disposed on the aforementioned support, and

[0018] The protective cover is hollow and covers the outer periphery of the heating element. The protective cover in the technical solution protects the heating element from the water or other debris flowing down from the sterilized object in the cabinet, and the hollow design of the protective cover is conducive to the heat exchange between the heating element and the cabinet.

[0019] In order to enhance the connection strength of the upper structure of the cabinet, preferably, the upper end surface of the rear plate is bent forward to form a folded edge, the folded edge is at least partially in contact with the lower surface of the top plate, and the top plate is formed with a convex bump at the contacting position, the convex bump is provided with a through screw hole, and a screw is provided in the screw hole to fix the rear plate and the top plate. The convex bump structure in this technical solution avoids the screw from slipping due to the thinness of the folded edge and the top plate.

[0020] Compared with the prior art, the advantages of the utility model are: the disinfection cabinet has protection for the heating component and the overall setting cost is low. Specifically, the positive projection of the heating device is on the first bent portion formed by the inward bending of the lower end of the rear plate. The first bent portion protects the bottom of the heating device. At the same time, the first bent portion also replaces the heavier bottom plate or supporting structure in the prior art. The structure is firm and light in weight, and the heating device has the advantages of low setting cost and compliance with safety regulations. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 8 The figure shows a preferred embodiment of the present utility model. The disinfection cabinet of this embodiment is mainly used for disinfecting some household dishes and chopsticks. When it needs to be installed at a certain location in the home, the disinfection cabinet needs to be relatively light and the core components need to operate well. For example, when the disinfection cabinet is transported from the warehouse to the home, it needs to have a lighter weight so that the disinfection cabinet can be moved conveniently and not easily bumped during transportation. However, while reducing the weight, it must also meet the safety standards for the production of disinfection cabinets. When the disinfection cabinet is working, the heating element inside it needs to be protected to extend the service life of the disinfection cabinet. At the same time, the connection relationship between the heating element and the disinfection cabinet is stable so that the heating element can generate heat at a fixed position when the disinfection cabinet is working, so that the heat exchange process in the cabinet is stable and repeatable, which is conducive to the quantification of heating power and time. Therefore, it will be beneficial to provide a disinfection cabinet with a low heating device installation cost and compliance with safety regulations. The following will expand the structural description of this disinfection cabinet:

[0031] See also Figures 1 to 3 The disinfection cabinet includes a cabinet body 1 and a heating device 2. The cabinet body 1 has a top plate 11, a rear plate 12 and side plates 13 located on both sides of the rear plate 12. The top plate 11, the rear plate 12 and the side plates 13 surround a disinfection cavity. The heating device 2 is arranged at the bottom of the disinfection cavity. The lower end of the cabinet body 1 is bent inward to form a first bending portion 3. The orthographic projection of the heating device 2 is on the first bending portion 3. The first bending portion 3 covers the bottom of the heating device 2.

[0032] In order to ensure that the heating device 2 can work in a fixed position and the overall airtightness of the disinfection cabinet, that is, the heating device 2 stabilizes the heat exchange process in the disinfection cavity, the cabinet 1 has a door frame 14 at the front end in this embodiment, the rear end of the mounting plate 4 is arranged above the first bending portion 3, the front end is connected to the door frame 14, and the heating device 2 is arranged on the upper end surface of the mounting plate 4. The connection between the mounting plate 4 and the cabinet 1 closes the bottom of the disinfection cavity, and the heating device 2 is fixed on the mounting plate 4 so that the relative position of the heating device and the cabinet remains unchanged when the disinfection cabinet is moved. The heating device 2 is fixed to the mounting plate 4 by bolts, and a cabinet door that opens outwards is also installed in the door frame 14. The cabinet 1 is provided with a bracket for placing objects to be disinfected and fixed to the inner wall of the cabinet 1 relative to the cabinet door. The inner wall of the cabinet 1 is also provided with a disinfection device relative to the bracket, and the disinfection device is provided with a disinfection device protective cover outside.

[0033] To make the disinfection cabinet meet safety regulations, please refer to Figures 4 to 5 In this embodiment, the first bending portion 3 includes a main body 31 and a vertical plate 5 extending vertically upward from the front end of the main body 31. This technical solution reduces the distance between the first bending portion 3 and the mounting plate 4.

[0034] Next, in order to further reduce the distance between the first bent portion 3 and the mounting plate 4, an inclined plate 6 is extended and arranged in the middle of the vertical plate 5 in this embodiment, and the upper end of the inclined plate 6 is against or close to the bottom surface of the mounting plate 4. In this technical solution, the inclined plate 6 reduces the distance between the first bent portion 3 and the mounting plate 4 and covers the bottom of the heating device 2, so that the first bent portion 3 has a protective effect on the heating device 2, which has the advantage of "one object with two uses".

[0035] In order to provide sufficient installation space for the heating device 2, the upper end surface of the mounting plate 4 in this embodiment is concave to form a groove 41, and the heating device 2 is limited in the groove 41. This technical solution increases the installation depth of the heating device 2.

[0036] Furthermore, the upper end surface of the mounting plate 4 has a groove 41, so that the bottom surface of the mounting plate 4 is raised downward to form a protrusion 42, and the inclined plate 6 abuts against or is close to the protrusion 42. This technical solution makes the inclined plate 6 and the bottom surface of the mounting plate 4 closer or even abutting each other, which is conducive to passing the safety inspection.

[0037] The heating device 2 of the disinfection cabinet needs to be placed stably during use, so the door frame 14 is bent inward to form a second bent portion 7, and the front end of the mounting plate is placed on the second bent portion 7. In this technical solution, the supporting structure connecting the front and rear ends of the mounting plate 4 is firm, and the mounting plate 4 can be placed horizontally and stably relative to the cabinet body 1.

[0038] In order to achieve normal operation of the heating device 2, please refer to Figure 6 In this embodiment, the heating device 2 includes two supports 21 arranged at intervals on the mounting plate 4, a strip-shaped heating element 22 with both ends arranged on the support 21, and a hollow protective cover 23 covering the outer periphery of the heating element 22. In this technical solution, the protective cover 23 protects the heating element 22 from the water or other debris flowing from the disinfected object in the cabinet 1. The hollow design of the protective cover 23 is conducive to the heat exchange between the heating element 22 and the cabinet. A drain plate fixed to the inner wall of the cabinet 1 is also provided between the heating device 2 and the bracket bracket. The drain plate has a drain hole with an arc-shaped edge that bends downward. A drain trough partially recessed downward for collecting running water is provided in the center of the drain plate. The bottom of the drain trough is staggered with the heating device 2 in the vertical direction to prevent the unevaporated water on the disinfected object from flowing to the surface of the heating device, thereby further protecting the heating element 22; the protective cover 23 and the first bending portion 3 wrap the heating element 22.

[0039] Finally, in order to enhance the structural strength of the upper part of the cabinet 1, please refer to Figures 7 and 8The upper end surface of the rear plate 12 is bent forward to form a folded edge 121, and the folded edge 121 is at least partially in contact with the lower surface of the top plate 11. The top plate 11 is formed with a convex bulge 111 at the contacting position, and a through screw hole 112 is opened on the convex bulge 111. A screw is set in the screw hole 112 to fix the rear plate 12 and the top plate 11. The convex bulge 111 structure in this technical solution avoids the screw from slipping due to the thin folded edge 121 and the top plate 11.

[0040] In summary, this disinfection cabinet can achieve the following functions according to user needs:

[0041] a. Compliance with safety regulations: The gap between the inclined plate 6 in the first bending portion 3 and the bottom surface of the groove 41 of the mounting plate 4 is small or even offset, so that the bottom of the heating device 2 is not likely to come into direct contact with the outside world, which complies with safety regulations.

[0042] b. Low installation cost: The lower part of the disinfection cabinet only has a mounting plate 4, a first bending portion 3 and a second bending portion 7. There is no other connecting device between the first bending portion 3 and the second bending portion 7, which eliminates the need for a traditional disinfection cabinet bottom plate and reduces weight.

[0043] c. Protection of the heating element 22: The fixed relationship between the mounting plate 4 and the heating device 2 allows the heating element 22 to stably operate at a specific position in the disinfection cabinet. The heating element 22 is also connected to a protective cover 23 with a hollow surface, so that unevaporated water does not contact the heating element 22 when flowing down, thereby preventing the heating element 22 from suddenly being cold and cracking or short-circuiting. The bottom of the heating device 2 is covered by the first bent portion 3, thereby preventing the heating element from being impacted from below when placed in the disinfection cabinet and reducing dust accumulation at the bottom of the heating device 2.

[0044] The present disinfection cabinet is provided with a first bent portion 3 at the bottom of the cabinet body 1, and a mounting plate 4 for fixing the heating device 2 is provided on the first bent portion 3. The first bent portion 3 enhances the structural strength of the cabinet body 1, so that the bottom plate does not need to be installed, saving the material of the supporting structure of the present heating device 2 and making the overall structure light; the first bent portion 3 and the protective cover 23 respectively cover the bottom and the top of the heating element 22, so that the heating device 2 avoids direct contact with unevaporated moisture and dust accumulation at the bottom and the impact from the bottom when the disinfection cabinet is carried, thereby ensuring the normal operation of the heating element, so that the present disinfection cabinet has the advantages of low installation cost of the heating device and compliance with safety regulations while being provided with a structure to protect the heating device.
