Description

Technical Field

[0001] This application relates to the field of disinfection electrical appliances technology, and in particular to a disinfection cabinet. Background Technology

[0002] Disinfection cabinets typically install heating elements above the bottom plate of the inner liner to heat the tableware placed inside for disinfection and drying. However, during the process of pulling out drawers and taking out tableware, small pieces of tableware may fall and touch the heating elements, causing damage or even smoke and fire. Furthermore, the heat from the heating elements diffuses upwards into the cabinet, with the area directly above them heating up faster and at a higher temperature, while other areas remain cooler. Excessive heat in the area directly above the heating elements can easily cause tableware to scorch or melt. Additionally, uneven temperature distribution within the cabinet can lead to variations in the disinfection and drying effectiveness of the tableware. Summary of the Invention

[0003] Therefore, it is necessary to provide a disinfection cabinet to address the above problems, in order to protect the heating element and tableware, and improve the uniformity of drying and disinfection.

[0004] This application provides a disinfection cabinet, including an inner liner, a drawer, a heating element, a protective cover, and a heat insulation cover; the inner liner has a disinfection chamber; the drawer passes through the disinfection chamber and is movably connected to the inner liner, and the bottom of the drawer has a plurality of spaced-apart first flow holes; the heating element is located below the drawer and installed in the inner liner; the protective cover is positioned above the heating element and below the drawer, spaced apart from the inner liner, and has a second flow hole; the heat insulation cover is positioned above the protective cover and below the drawer, and has a third flow hole, which is staggered from the second flow hole and communicates with the first flow hole; the disinfection cabinet has a first preset temperature, and the heat insulation cover is configured to be separated from the protective cover when the actual temperature of the heating element is lower than the first preset temperature, and to be in contact with the protective cover when the actual temperature of the heating element is not lower than the first preset temperature; wherein, in the contacted state, at least directly above the heating element, the heat insulation cover and the protective cover are in contact.

[0005] Understandably, the heating element provides heat to dry and sterilize the tableware inside the drawer. A protective cover is positioned above the heating element to protect it and prevent damage from falling tableware. The protective cover has a second flow hole to facilitate heat diffusion. Above the protective cover is a heat insulation cover. When the temperature of the heating element is below a first preset temperature, the heat insulation cover separates from the protective cover, allowing heat to pass through the second, third, and first flow holes to reach the drawer interior. Most of the heat is transferred upwards from directly above the heating element. When the temperature of the heating element reaches the first preset temperature, at least directly above the heating element, the heat insulation cover is attached to the protective cover. Due to the staggered arrangement of the second and third flow holes, the heat insulation cover, when attached to the protective cover, blocks the second flow hole, providing insulation and reducing the heat transferred upwards from the heating element. This allows most of the heat to diffuse outwards, promoting temperature uniformity inside the sterilizer and improving the sterilization and drying effect.

[0006] In one embodiment, the heating element has a second preset temperature T2, which is greater than a first preset temperature T1; the heating element is configured to pause in response to an actual temperature t reaching the second preset temperature T2; the heating element also has a third preset temperature T3, which is lower than the first preset temperature T1, and the heating element is configured to restart in response to an actual temperature t decreasing to the third preset temperature T3.

[0007] With this setup, the heating element operates intermittently. The opening and closing of the heating element is controlled by setting a second preset temperature and a third preset temperature. The heating element's temperature rise and fall during this process are used to switch the cooperation state between the heat insulation cover and the protective cover, so as to promote uniform heat distribution in the disinfection chamber.

[0008] In one embodiment, 0.6T1≤T3≤0.8T1; and / or, 1.1T1≤T2≤1.25T1.

[0009] This configuration, by limiting the range of the third preset temperature, ensures that the heating element has sufficient time to output heat upwards. By limiting the range of the second preset temperature, it controls the time for the heating element to output heat in all directions, preventing excessive heat from the surrounding areas and promoting uniform heat distribution.

[0010] In one embodiment, the protective cover includes a first guide plate and a second guide plate connected to each other, the first guide plate and the second guide plate being respectively inclined in the height direction, and the protective cover enclosing a space that gradually increases in size from the top toward the heating element along the height direction.

[0011] This configuration, with the first and second guide plates, facilitates the diffusion of heat to the surrounding area of ​​the heating element.

[0012] In one embodiment, the angle between the tilt direction of the first guide plate or the tilt direction of the second guide plate and the height direction is α, where 45°≤α≤70°.

[0013] This configuration, by limiting the tilt angle of the first or second guide plate, ensures that the first or second guide plate forms a sufficiently tilted surface to guide airflow and avoids excessive obstruction of airflow.

[0014] In one embodiment, the protective cover further includes a guard plate disposed opposite to the heating element along the height direction, the guard plate extending straight and connected between the first guide plate and the second guide plate.

[0015] This design allows hot air directly above the heating element to flow upwards through the guard plate.

[0016] In one embodiment, the disinfection cabinet further includes a first magnetic component and a second magnetic component that attract each other. The first magnetic component is mounted on the bottom plate of the drawer, and the second magnetic component is mounted on the heat insulation cover. The attraction between the first magnetic component and the second magnetic component is configured to change in response to temperature changes of the heating element.

[0017] This configuration allows the state of the heat shield relative to the protective shield to be switched by the change in the attraction force between the first and second magnetic components as the temperature changes. This fully utilizes the thermal energy of the heating element itself without the need for additional energy sources, and eliminates the need for designing other complex mechanisms to switch the position of the heat shield, making it easy to operate.

[0018] In one embodiment, the heat insulation cover includes a third guide plate, a mating plate, and a fourth guide plate. Along the height direction, the mating plate is disposed opposite to the heating element. The mating plate extends straight and is connected between the third guide plate and the fourth guide plate. The mating plate is equipped with the second magnetic element. The third guide plate and the fourth guide plate are respectively inclined relative to the height direction. The heat insulation cover encloses a space that gradually increases in size from the top toward the protective cover along the height direction.

[0019] This design, along with the placement of the mounting plate, facilitates attachment to the bottom of the drawer or to the protective cover. When the heat insulation cover is separated from the protective cover, the third and fourth guide plates guide the airflow between the heat insulation cover and the protective cover to diffuse outwards, allowing a small portion of the heat from the heating element to spread outwards.

[0020] In one embodiment, the heat insulation cover further includes a first extension plate connected to the side of the third guide plate away from the heating element, the first extension plate extending along a first direction; and / or, the heat insulation cover further includes a second extension plate connected to the side of the fourth guide plate away from the heating element, the second extension plate extending along a first direction; the first direction is angled to the height direction.

[0021] This configuration allows the first extension plate to further guide the hot airflow to diffuse around the side away from the heating element. The second extension plate further guides the hot airflow to diffuse around the other side away from the heating element.

[0022] In one embodiment, along the second direction, fifth guide plates are respectively provided on both sides of the mating plate, and the fifth guide plates are inclined downward from the mating plate; the second direction is set at an angle to the height direction.

[0023] With this design, the fifth guide plate can guide the falling tableware to slide downwards, minimizing the amount of tableware remaining in the heat insulation cover.

[0024] In one embodiment, the third guide plate and the fourth guide plate are bent toward the drawer side to form a ridge, and each ridge forms a groove toward the heating element. The ridge is provided with the third flow hole, and the ridge is staggered with the second flow hole.

[0025] This design allows for quick positioning and processing of the third flow hole. At the same time, each protrusion forms a groove on the side facing the heating element, which helps to reduce the contact area between the heat insulation cover and the protective cover when they are attached.

[0026] In one embodiment, the heating element includes a heating tube and two heating seats. The heating tube extends along a first direction, and a corresponding heating seat is installed at each end of the heating tube along the first direction. The disinfection cabinet also includes a support member, which is installed above the heating seat and connected between the heating seat and the protective cover.

[0027] This configuration allows the two heating bases to jointly support the heating element, ensuring the stability of the heating element assembly. The support components are also included to support the protective cover, promoting stable assembly of the protective cover. Attached Figure Description

[0036] Please see Figures 1 to 8This application provides a disinfection cabinet 100, which includes an inner liner 10 and a drawer 20. The inner liner 10 has a disinfection chamber 101, and the drawer 20 passes through the disinfection chamber 101 for placing tableware so that the tableware can be disinfected in the disinfection chamber 101. The drawer 20 is movably connected to the inner liner 10 so that it can be pulled out relative to the inner liner 10, which facilitates the opening and closing of the drawer 20.

[0037] like Figure 1 and Figure 3 As shown, the disinfection cabinet 100 also includes a heating element 30, which is located below the drawer 20 and installed in the inner liner 10 to provide a heat source for the disinfection chamber 101. The heat can rise naturally to dry and disinfect the tableware in the disinfection chamber 101 at high temperature.

[0038] like Figure 2 , Figure 4 and Figure 6 As shown, the disinfection cabinet 100 also includes a protective cover 40, which is positioned above the heating element 30 and below the drawer 20 to protect the heating element 30 and prevent tableware from accidentally falling and colliding with it when the drawer 20 is moved or tableware is being taken out or put in. Figure 8 As shown, the bottom of drawer 20 has multiple spaced-apart first flow holes 201. Figure 7 As shown, the protective cover 40 is provided with a second flow hole 401, allowing the heat from the heating element 30 to directly enter the drawer 20 through the second flow hole 401 and the first flow hole 201, thus improving heat transfer efficiency. The protective cover 40 is spaced apart from the inner liner 10, creating a gap between them. The heat from the heating element 30 can diffuse outward from this gap to the outside of the protective cover 40, and then enter the drawer 20 through the first flow hole 201.

[0039] like Figure 2 and Figure 5 As shown, the disinfection cabinet 100 also includes a heat insulation cover 50, which is located above the protective cover 40 and below the drawer 20. The heat insulation cover 50 has a third flow hole 501, which is staggered with the second flow hole 401. The heating element 30 has a first preset temperature. The heat insulation cover 50 is configured to be separated from the protective cover 40 when the actual temperature of the heating element 30 is lower than the first preset temperature, and to be in contact with the protective cover 40 when the actual temperature of the heating element 30 is not lower than the first preset temperature. In the contacted state, the heat insulation cover 50 and the protective cover 40 are in contact at least directly above the heating element 30.

[0040] In other words, when the actual temperature of the heating element 30 is lower than the first preset temperature, the heat insulation cover 50 separates from the protective cover 40, and a sandwich space is formed between the heat insulation cover 50 and the protective cover 40. Most of the heat from the heating element 30 can directly pass upward through the second flow hole 401, the third flow hole 501 and the first flow hole 201 in sequence, and directly enter the drawer 20. The heat from the heating element 30 mainly enters the space of the drawer 20 from directly above for heating. Of course, a small portion of the heat bypasses the protective cover 40 and enters the drawer 20, and a small portion of the heat enters the sandwich space and diffuses to the surroundings before entering the drawer 20. When the actual temperature of the heating element 30 reaches the first preset temperature, at least directly above the heating element 30, the heat insulation cover 50 and the protective cover 40 are in contact. Due to the staggered arrangement of the third flow hole 501 and the second flow hole 401, both the second flow hole 401 and the third flow hole 501 are blocked. The heat insulation cover 50 and the protective cover 40 together block the heat transfer directly above the heating element 30, so that most of the heat from the heating element 30 diffuses to the surrounding area and enters the drawer 20. This arrangement promotes uniform heat distribution in the sterilization chamber 101, avoids local overheating that could damage the tableware, and improves the uniformity of drying and sterilizing the tableware.

[0041] In an optional embodiment, the heating element 30 has a second preset temperature T2, which is greater than a first preset temperature T1. The heating element 30 is configured to pause in response to the actual temperature t reaching the second preset temperature T2. The heating element 30 also has a third preset temperature T3, which is lower than the first preset temperature T1. The heating element 30 is configured to restart in response to the actual temperature t decreasing to the third preset temperature T3. Thus, before the actual temperature of the heating element 30 reaches the first preset temperature, the heat insulation cover 50 separates from the protective cover 40, and most of the heat from the heating element 30 is transferred upwards. When the actual temperature of the heating element 30 reaches the first preset temperature but is lower than the second preset temperature, the heat insulation cover 50 and the protective cover 40 are in a fitted state, and most of the heat from the heating element 30 is transferred to the surroundings. After the heating element 30 reaches the second preset temperature, the heating element 30 pauses, and the temperature in the heating element 30 and the disinfection chamber 101 gradually cools down. When the heating element 30 cools down to an actual temperature between the second preset temperature and the first preset temperature, the heat insulation cover 50 and the protective cover 40 remain in a fitted state. When the heating element 30 cools down to a temperature lower than the first preset temperature but higher than the third preset temperature, the heat insulation cover 50 and the protective cover 40 switch from a fitted state to a separated state. When the heating element 30 cools down to a temperature reaching the third preset temperature, the heating element 30 restarts and begins the cycle again. During each cycle, between the first and third preset temperatures, the heat from the heating element 30 mainly diffuses upwards; between the first and second preset temperatures, the heat from the heating element 30 mainly diffuses outwards.

[0042] In a specific embodiment, 0.6T1 ≤ T3 ≤ 0.8T1. Thus, since the heat from the heating element 30 mainly diffuses upwards between the first and third preset temperatures, and the temperature within this range is relatively high but lower than the temperature between the first and second preset temperatures, limiting the range of the third preset temperature allows the heating element 30 sufficient time to output heat upwards, ensuring the drying and sterilization effect of the tableware in the sterilization chamber 101 directly above the heating element 30. For example, T3 = 0.6T1, 0.7T1, or 0.8T1.

[0043] In a specific embodiment, 1.1T1≤T2≤1.25T1. Thus, since the heat from the heating element 30 mainly diffuses outwards between the first and second preset temperatures, resulting in high temperatures within this range, limiting the range of the second preset temperature controls the time it takes for the heating element 30 to output heat outwards, preventing excessively high temperatures in the surrounding areas and promoting uniform heat distribution. For example, T2 = 1.1T1, 1.2T1, or 1.25T1.

[0044] like Figure 2 and Figure 4 As shown, in a specific embodiment, the disinfection cabinet 100 further includes a first magnetic component 61 and a second magnetic component 62 that attract each other. The first magnetic component 61 is mounted on the bottom plate 21 of the drawer 20, and the bottom plate 21 and the first magnetic component 61 together form the bottom of the drawer 20. The bottom plate 21 and the first magnetic component 61 are respectively provided with a first flow hole 201. The second magnetic component 62 is mounted on the heat insulation cover 50. Through the magnetic attraction of the first magnetic component 61 and the second magnetic component 62, the heat insulation cover 50 can be separated from the protective cover 40 and adsorbed onto the bottom of the drawer 20 after the drawer 20 is closed. The attraction of the first magnetic component 61 and the second magnetic component 62 is configured to change in response to the temperature change of the heating element 30. When the temperature rises, the attraction force between the first magnetic component 61 and the second magnetic component 62 gradually decreases, and when the temperature decreases, the attraction force between the first magnetic component 61 and the second magnetic component 62 gradually increases. When the actual temperature of the heating element 30 reaches the first preset temperature, the attraction between the second magnetic element 62 and the first magnetic element 61 is insufficient to fix the heat insulation cover 50 to the bottom of the drawer 20. At this time, the heat insulation cover 50 falls off and attaches to the protective cover 40. When the actual temperature of the heating element 30 is lower than the first preset temperature, the attraction between the second magnetic element 62 and the first magnetic element 61 is restored, so that the heat insulation cover 50 is re-attracted to the bottom of the drawer 20. By changing the attraction between the first magnetic element 61 and the second magnetic element 62 with temperature to switch the state of the heat insulation cover 50 relative to the protective cover 40, the thermal energy of the heating element 30 itself is fully utilized without the need for additional energy sources, and no other complex mechanisms are required to switch the position of the heat insulation cover 50, making operation simple.

[0045] like Figure 2 and Figure 4 As shown, in a specific embodiment, the base plate 21 has an assembly hole 202 that extends through the height direction, and the first magnetic component 61 is installed in the assembly hole 202.

[0046] like Figure 2 and Figure 4 As shown, in a specific embodiment, the base plate 21 is provided with a pressing part 211 at the edge of the mounting hole 202. The pressing part 211 is formed by bending the base plate 21. The pressing part 211 protrudes relative to the space inside the drawer 20 along the height direction. The side of the pressing part 211 facing the heat insulation cover 50 forms a first mounting groove 203. The first mounting groove 203 communicates with the mounting hole 202. The first magnetic component 61 is embedded in the first mounting groove 203. The groove wall of the first mounting groove 203 limits the first magnetic component 61 along the height direction and along the circumference of the first magnetic component 61, promoting the stability of the assembly of the first magnetic component 61. At the same time, the first magnetic component 61 is accommodated by the first mounting groove 203 so that the bottom of the drawer 20 remains flat.

[0047] like Figure 2 , Figure 4 and Figure 6 As shown, in a specific embodiment, the second magnetic component 62 is disposed on the side of the heat insulation cover 50 facing the protective cover 40. The heat insulation cover 50 is provided with a second assembly groove 502, and the second magnetic component 62 is installed in the second assembly groove 502. The groove wall of the second assembly groove 502 limits the second magnetic component 62 along the height direction and along the circumference of the second magnetic component 62, promoting the stability of the assembly of the second magnetic component 62. At the same time, by accommodating the second magnetic component 62 through the second assembly groove 502, the surface of the heat insulation cover 50 is kept flat, which facilitates the heat insulation cover 50 to form a good fit with the protective cover 40 when the actual temperature of the heating element 30 reaches the first preset temperature, ensuring the sealing effect of the second flow hole 401 and the third flow hole 501 in the fitted state.

[0048] like Figure 5 and Figure 6 As shown, in a specific embodiment, the heat insulation cover 50 has a protrusion 531 on the side facing the drawer 20. The protrusion 531 forms the aforementioned second assembly groove 502, so that the second assembly groove 502 has sufficient space to accommodate the second magnetic component 62, ensuring the reliability of the assembly. When the actual temperature of the heating component 30 is lower than the first preset temperature, the protrusion 531 is attached to the surface of the first magnetic component 61 by the adsorption between the second magnetic component 62 and the first magnetic component 61. This allows the heat insulation cover 50 to form a gap with the first magnetic component 61 around the protrusion 531, so that the first flow hole 201 and the third flow hole 501 can be connected through the gap.

[0049] like Figure 2 , Figure 4 and Figure 6 As shown, in a specific embodiment, the protective cover 40 includes a first guide plate 41 and a second guide plate 42 connected to each other. The first guide plate 41 and the second guide plate 42 are respectively inclined in the height direction. The protective cover 40 surrounds a space that gradually increases in height from the top toward the heating element 30. In this way, the hot air around the heating element 30 can flow along the inclined direction of the first guide plate 41 and the second guide plate 42 to promote the diffusion of heat to the surroundings of the heating element 30 when the heat insulation cover 50 and the protective cover 40 are in contact.

[0050] In a specific embodiment, the tilt angle of the first guide plate 41 relative to the height direction is the same as that of the second guide plate 42 relative to the height direction, so that the airflow guiding effect formed on both sides of the heating element 30 is the same, promoting the uniform diffusion of heat.

[0051] like Figure 6 As shown, in a specific embodiment, the angle between the tilt direction of the first guide plate 41 or the tilt direction of the second guide plate 42 and the height direction is α, where 45°≤α≤70°. By limiting the tilt angle of the first guide plate 41 or the second guide plate 42, the first guide plate 41 or the second guide plate 42 forms a sufficiently tilted surface, while avoiding excessive obstruction of airflow, promoting smooth airflow and facilitating the outward diffusion of heat. For example, α = 45°, 60°, or 70°.

[0052] like Figure 2 , Figure 4 and Figure 6 As shown, in a specific embodiment, the protective cover 40 further includes a guard plate 43 disposed opposite to the heating element 30 along the height direction. The guard plate 43 extends straight and is connected between the first guide plate 41 and the second guide plate 42. Thus, the guard plate 43 is disposed so that hot air directly above the heating element 30 can flow upward through the guard plate 43, promoting the efficiency of heat transfer from directly above.

[0053] like Figure 7 As shown, in a specific embodiment, the heating element 30 includes a heating tube 31 and two heating seats 32. The heating tube 31 extends along a first direction to increase heat. Along a second direction, a corresponding heating seat 32 is installed at each end of the heating tube 31. The two heating seats 32 jointly support the heating tube 31 to ensure the stability of the heating tube 31 assembly.

[0054] like Figure 5 and Figure 6 As shown, in a specific embodiment, the disinfection cabinet 100 also includes a support member 70, which is installed above the heating base 32 and connected between the heating base 32 and the protective cover 40. The support member 70 is provided to support the protective cover 40 and promote the stable assembly of the protective cover 40.

[0055] like Figure 5 As shown, in a specific embodiment, the support member 70 includes a connecting plate 71 and a support plate 72. The connecting plate 71 is attached to the upper surface of the heating base 32, and the two are connected by surface-to-surface contact to form a large contact area to ensure assembly stability. The support plate 72 is connected to the connecting plate 71 and is set at an angle to the connecting plate 71. The side of the support plate 72 away from the connecting plate 71 is connected to the protective cover 40 to support the protective cover 40.

[0056] like Figure 5 and Figure 6 As shown, in a specific embodiment, the heat insulation cover 50 includes a third guide plate 51, a mating plate 53, and a fourth guide plate 52. Along the height direction, the mating plate 53 is positioned opposite the heating element 30. The mating plate 53 extends straight and connects between the third guide plate 51 and the fourth guide plate 52. A second magnetic element 62 is mounted on the mating plate 53. The mating plate 53 is designed to be easily attached to the bottom of the drawer 20, and it can also form a close fit with the protective plate 43. Figure 2 and Figure 4 As shown, the mating plate 53 forms the aforementioned second mounting groove 502. The third guide plate 51 and the fourth guide plate 52 are respectively inclined in the height direction, and the heat insulation cover 50 surrounds a space that gradually increases in height from the top towards the protective cover 40. With this arrangement, when the heat insulation cover 50 is separated from the protective cover 40, the third guide plate 51 and the fourth guide plate 52 can guide the airflow between the heat insulation cover 50 and the protective cover 40 to diffuse outward, so that a small portion of the heat from the heating element 30 can diffuse in all directions. In addition, when the heat insulation cover 50 and the protective cover 40 are in contact, the above arrangement allows the third guide plate 51 to contact with the first guide plate 41, and the fourth guide plate 52 to contact with the second guide plate 42, thereby promoting the diffusion of hot airflow around the heating element 30 in a direction away from the heating element 30.

[0057] like Figure 5 and Figure 6 As shown, in a specific embodiment, the heat insulation cover 50 further includes a first extension plate 54. The first extension plate 54 is connected to the side of the third guide plate 51 away from the heating element 30. The first extension plate 54 extends along a first direction. When the heat insulation cover 50 and the protective cover 40 are attached together, the first extension plate 54 can extend outward relative to the protective cover 40. The arrangement of the first extension plate 54 can further guide the hot airflow to diffuse around the side away from the heating element 30.

[0058] like Figure 5 and Figure 6As shown, in a specific embodiment, the heat insulation cover 50 further includes a second extension plate 55. The second extension plate 55 is connected to the side of the fourth guide plate 52 away from the heating element 30. The second extension plate 55 extends along the first direction. When the heat insulation cover 50 and the protective cover 40 are attached together, the second extension plate 55 can extend outward relative to the protective cover 40. The arrangement of the second extension plate 55 can further guide the hot airflow to diffuse around the other side away from the heating element 30.

[0059] like Figure 5 and Figure 7 As shown, in a specific embodiment, along the second direction, the mating plate 53 is provided with a fifth guide plate 56 on both sides. The fifth guide plate 56 is inclined downward from the mating plate 53. While guiding the airflow between the heat insulation cover 50 and the protective cover 40 to diffuse, it can also guide the falling tableware to slide downward, so as to minimize the tableware from remaining on the heat insulation cover 50.

[0060] In this application, the first direction, the second direction, and the height direction are set at angles to each other. For ease of explanation, the first direction, the second direction, and the height direction are set perpendicular to each other, and a rectangular coordinate system is introduced, with the first direction as the x-axis, the second direction as the y-axis, and the height direction as the z-axis.

[0061] like Figure 5 and Figure 6 As shown, in a specific embodiment, the third guide plate 51 and the fourth guide plate 52 are bent towards the drawer 20 to form a protrusion 503. The protrusion 503 is provided with a third flow hole 501, and the protrusion 503 is staggered with the second flow hole 401. In this way, the protrusion 503 is set to facilitate the rapid positioning and processing of the third flow hole 501, and to allow the third flow hole 501 to naturally form a misalignment with the second flow hole 401. At the same time, each protrusion 503 forms a groove 504 on the side facing the heating element 30. When the heat insulation cover 50 and the protective cover 40 are attached, it ensures that the second flow hole 401 is blocked by the heat insulation cover 50, thereby reducing the contact area between the heat insulation cover 50 and the protective cover 40 and avoiding the heat insulation cover 50 and the protective cover 40 from being too close together and difficult to separate.

[0062] The disinfection cabinet 100 can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the disinfection cabinet 100 to perform corresponding operations, thereby realizing the intelligent control of the disinfection cabinet 100 and improving the user experience.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
