Description

Technical Field

[0001] This utility model relates to a disinfection cabinet and belongs to the technical field of kitchen appliances. Background Technology

[0002] A disinfection cabinet is a tool that uses ultraviolet light, infrared light, high temperature, and ozone to disinfect, sterilize, dry, keep warm, and store tableware, clothing, medical devices, etc. Existing disinfection cabinets mainly rely on the principles of high temperature and ultraviolet sterilization. The main components inside the machine are a heater and an ultraviolet lamp. The heater is generally an infrared heating tube, and the ultraviolet lamp requires a starter to increase the voltage at both ends during use, while a ballast regulates the current stability.

[0003] In existing technologies, ballasts and starters are usually installed on the rear wall panel of the inner liner of the disinfection cabinet. The high-temperature environment generated by the heater and ultraviolet disinfection tube during operation can adversely affect the ballasts and starters, potentially causing aging of their insulation materials, deterioration of circuit performance, or even damage. Utility Model Content

[0004] The purpose of this invention is to provide a disinfection cabinet that can keep the ballast and starter away from high-temperature environments, ensuring their normal function and service life.

[0005] This utility model is achieved through the following technical solution.

[0006] A disinfection cabinet includes an inner liner with at least one disinfection chamber inside. The rear wall panel of the inner liner is provided with a fan for generating circulating air in the disinfection chamber and a heater for heating the circulating air in the disinfection chamber for each of the disinfection chambers. Each of the disinfection chambers is provided with an ultraviolet disinfection tube.

[0007] Additionally, a frame located outside the inner liner and used for assembling the inner liner, the frame including an upper mounting plate corresponding to the top wall panel of the inner liner, the upper mounting plate being equipped with a ballast and a starter corresponding to the ultraviolet disinfection tube of each disinfection chamber.

[0008] As a further improvement of this utility model, the frame includes two wall panels, which correspond to the two side wall panels of the inner liner respectively, and the upper mounting plate extends laterally and its two ends are fixedly connected to the two wall panels respectively.

[0009] As a further improvement of this utility model, the side wall panel of the inner liner has an upwardly extending mounting portion at the connection with the top wall panel, and the two ends of the upper mounting plate are respectively attached to the corresponding mounting portions. The upper mounting plate is provided with fasteners, which penetrate the mounting portions and are fixedly connected to the wall panel.

[0010] As a further improvement of this utility model, the wall panel is provided with a plurality of wall panel reinforcing ribs formed by recesses or protrusions.

[0011] As a further improvement of this utility model, the frame also includes a rear mounting plate corresponding to the rear wall panel of the inner liner, and the fan is provided with fasteners, which penetrate the rear wall panel of the inner liner and are fixedly connected to the rear mounting plate.

[0012] As a further improvement of this utility model, a power board mounting base is provided on the rear mounting plate for mounting the power board.

[0013] As a further improvement of this utility model, the frame also includes a horizontally extending support beam, the two ends of which are fixedly connected to the two wall panels respectively, and corresponding to the bottom of the rear wall panel of the inner liner, the rear mounting plate extends vertically, with its two ends fixedly connected to the upper mounting plate and the support beam respectively.

[0014] As a further improvement of this utility model, the top and bottom ends of the rear mounting plate are both bent into folded edges, and the two folded edges are respectively attached to the upper mounting plate and the support beam, and are fixedly connected by fasteners.

[0015] As a further improvement of this utility model, the rear mounting plate is provided with a plurality of mounting plate reinforcing ribs formed by recesses or protrusions.

[0016] As a further improvement of this utility model, the frame also includes two vertically extending side mounting plates, which are located on both sides of the rear mounting plate and are fixedly connected at both ends to the upper mounting plate and the support beam, respectively. The side mounting plates are used to install electromagnetic locks.

[0017] The beneficial effects of this utility model are:

[0018] The ballast and starter of the disinfection cabinet are mounted on the upper mounting plate, keeping them away from the fan and heater. This effectively controls the overheating of these two electronic components. Since the heater inside the disinfection chamber operates at a high temperature, and the circulating air from the fan also carries heat, exposing the ballast and starter to this high-temperature environment could lead to aging of insulation materials, decreased circuit performance, or even damage. For example, high temperatures can cause circuit parameter drift (such as changes in capacitance or thermal runaway of semiconductor devices). The external placement of the ballast and starter allows them to operate at room temperature, ensuring the stability of the sterilization system, extending component lifespan, optimizing heat dissipation, avoiding direct contact with hot and humid airflow, and simplifying maintenance (no need to disassemble the inner liner for repairs).

[0027] A disinfection cabinet, as shown in the reference Figures 1-5 The system includes an inner liner 1 and a frame. The inner liner 1 contains at least one disinfection chamber r, defined by a top wall panel 11, two side wall panels 13, a rear wall panel 12, and a bottom wall panel. The number of disinfection chambers r is determined by partitions within the inner liner. For example, the inner liner 1 shown in this embodiment has a horizontally arranged partition that divides the interior of the inner liner 1 into upper and lower disinfection chambers r. A fan 21 and a heater 22 are provided on the rear wall panel 12 of the inner liner 1 for each disinfection chamber r. The fan 21 generates circulating air within the corresponding disinfection chamber r, and the heater 22 heats the circulating air within the disinfection chamber r, thereby achieving a hot air circulation disinfection mode within the disinfection chamber r. The heater 22 can specifically use a heating tube, such as an infrared quartz heating tube. Furthermore, each disinfection chamber r of the inner liner 1 is also equipped with an ultraviolet disinfection tube 23, which works in conjunction with the hot air circulation to enhance the disinfection effect.

[0028] The frame is installed outside the inner liner 1, and the inner liner 1 is assembled on the frame. The frame includes an upper mounting plate 31, which corresponds to the top wall plate 11 of the inner liner 1. Specifically, it is installed on or above the top wall plate 11 of the inner liner 1. The upper mounting plate 31 is equipped with a ballast 41 and a starter 42 corresponding to the ultraviolet disinfection tube 23 of each disinfection chamber r. For example, in the inner liner 1 with two disinfection chambers r shown in this embodiment, correspondingly, two ballasts 41 and two starters 42 are provided.

[0029] The ballast 41 and starter 42 of the disinfection cabinet are mounted on the upper mounting plate 31, keeping them away from the fan 21 and heater 22. This effectively controls the overheating of these two electronic components. Since the heater 22 inside the disinfection chamber operates at a high temperature (typically around 120°C), and the circulating air generated by the fan 21 also carries heat, if the ballast 41 and starter 42 are exposed to this high-temperature environment, it may cause aging of insulation materials, deterioration of circuit performance, or even damage. For example, high temperatures may cause circuit parameter drift (such as changes in capacitance or thermal runaway of semiconductor devices). The external placement of the ballast 41 and starter 42 allows them to operate at room temperature, ensuring the stability of the sterilization system, extending the lifespan of the components, optimizing heat dissipation, avoiding direct contact with hot and humid airflow, and simplifying maintenance (no need to disassemble the inner liner 1 during maintenance).

[0030] In this embodiment, the frame includes two wall panels 32, corresponding to the two side wall panels 13 of the inner liner 1, respectively. An upper mounting plate 31 extends laterally and is fixedly connected at both ends to the two wall panels 32. The rigid connection between the wall panels 32 and the upper mounting plate 31 enhances the overall structural stability of the frame. The two side wall panels 32 directly correspond to the side walls of the inner liner 1, forming a symmetrical support system. This effectively distributes the load on the inner liner 1 and its internal components (such as the fan 21 and heater 22), reducing the risk of deformation due to vibration or long-term use. The laterally extending upper mounting plate 31 provides an independent mounting platform for electronic components such as the ballast 41 and starter 42, preventing direct contact between them and the side walls of the inner liner 1. This reduces thermal damage to the electronic components caused by high-temperature conduction (the heater 22 in the inner liner 1 can reach 120℃ during operation), extending their service life. Furthermore, this modular structure simplifies the assembly process; the wall panels 32 and the upper mounting plate 31 can be prefabricated and then assembled, improving production efficiency and maintenance convenience.

[0031] In this embodiment, the side wall panel 13 of the inner liner 1 has an upwardly extending mounting portion 131 at its connection with the top wall panel 11. The mounting portion 131 and the side wall panel 13 are an integral structure. The two ends of the upper mounting plate 31 are respectively attached to the corresponding mounting portions 131. The upper mounting plate 31 is provided with fasteners, which penetrate the mounting portions 131 and are fixedly connected to the wall panel 32. After the fasteners penetrate the mounting portions 131 and are locked to the wall panel 32, a three-point rigid fixation is formed (side wall panel 13 - mounting portion 131 - upper mounting plate 31 - wall panel 32). Its shear resistance is better than that of traditional single-point welding or cantilever support structures, which can effectively suppress the lateral displacement of the inner liner 1 caused by its own weight or transportation vibration. At the same time, the close contact surface between the mounting portion 131 and the upper mounting plate 31 increases the friction area. Combined with the pre-tightening force of the through fasteners, it can resist the microscopic misalignment caused by metal expansion under high temperature environment and prevent the connection from loosening.

[0032] In this embodiment, multiple wall panel reinforcing ribs 321 formed by recesses or protrusions are arranged on the wall panel 32. The reinforcing ribs form a three-dimensional support network through local deformation, which greatly improves the bending stiffness and torsional strength of the wall panel 32 without increasing its thickness, and effectively suppresses the deformation of the wall panel 32 caused by the weight of the inner liner 1, the vibration of the fan 21 or the thermal expansion of high temperature.

[0033] In this embodiment, the frame also includes a rear mounting plate 33, which corresponds to the rear wall panel 12 of the inner liner 1. The rear mounting plate 33 can be fitted snugly onto the rear wall panel 12, or a gap can be left between them. The fan 21 is equipped with fasteners that penetrate the rear wall panel 12 of the inner liner 1 and are fixedly connected to the rear mounting plate 33. The vibration generated by the fan 21 during operation is directly transmitted to the rear mounting plate 33 through the fasteners, rather than relying solely on the support of the rear wall panel 12 of the inner liner 1 for the fan 21. The rigid base of the rear mounting plate 33 disperses the vibration energy, preventing fatigue cracking of the thin-walled structure of the inner liner 1 due to long-term alternating stress. In addition, when disassembling the fan 21, only the fasteners of the rear mounting plate 33 need to be released, without damaging the sealing of the inner liner 1, thus improving the convenience of installation and disassembly.

[0034] In this embodiment, a power board mounting bracket 332 is provided on the rear mounting plate 33 for mounting the power board. For example, in the inner liner 1 with two disinfection chambers r shown in this embodiment, the power board mounting bracket 332 is located in the middle of the rear mounting plate 33, between the two motor connection points. The power board and the fan 21 share the maintenance channel of the rear mounting plate 33, allowing for simultaneous inspection and maintenance of the power supply and fan 21 without disassembling the inner liner 1, significantly reducing troubleshooting time.

[0035] In this embodiment, the frame also includes a support beam 34, which extends laterally and is fixedly connected at both ends to two wall panels 32, corresponding to the bottom of the rear wall panel 12 of the inner liner 1. A rear mounting plate 33 extends vertically, with both ends fixedly connected to the upper mounting plate 31 and the support beam 34. The transverse support beam 34, acting as the bottom load-bearing skeleton, forms a closed bending section with the side wall panels 32, effectively bearing the vertical loads of the rear wall panel 12 of the inner liner 1 and the fan 21 (such as the weight of the disinfection chamber r when fully loaded), distributing the loads to the reinforcing ribs 321 of the side wall panels, thus avoiding localized depressions in the wall panels 32 caused by stress concentration at a single point. The vertical extension design of the rear mounting plate 33, together with the upper mounting plate 31 and the support beam 34, forms an "I"-shaped three-dimensional frame, significantly improving torsional stiffness and suppressing shear damage to the connecting structure caused by the periodic vibrations generated when the fan 21 rotates at high speed.

[0036] In this embodiment, the top and bottom ends of the rear mounting plate 33 are both bent into flanges 333. The two flanges 333 are respectively attached to the upper mounting plate 31 and the support beam 34 and are fixedly connected by fasteners. The bending structure of the flanges 333 (usually formed by stamping) upgrades the contact surface between the rear mounting plate 33 and the upper mounting plate 31 and the support beam 34 from planar contact to three-dimensional interlocking. The inner side of the flange forms a line-surface composite contact with the connecting surface, which greatly increases the effective friction area and improves the preload of the fasteners.

[0037] In this embodiment, the rear mounting plate 33 is provided with multiple recessed or protruding mounting plate reinforcing ribs 331, which greatly improve its bending stiffness and torsional strength, thereby improving the connection firmness of the fan 21.

[0038] In this embodiment, the frame also includes two side mounting plates 35, which extend vertically and are located on both sides of the rear mounting plate 33. Their ends are fixedly connected to the upper mounting plate 31 and the support beam 34, respectively. The side mounting plates 35 are used to install electromagnetic locks. The side mounting plates 35, together with the upper mounting plate 31 and the support beam 34, form a closed three-dimensional frame, significantly improving lateral bending stiffness. This allows for the even distribution of the impact force of the electromagnetic lock closing the door and the lateral load when the disinfection chamber is fully loaded. Furthermore, it also allows for the installation of electromagnetic locks.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
