Description

Technical Field

[0001] This invention relates to the field of tableware disinfection, and in particular to a disinfection cabinet. Background Technology

[0002] In tableware sterilizers, ultraviolet (UV) lamps are typically installed on the rear wall of the cabinet. This way, when the drawer is pulled out, the tableware inside is less likely to interfere with the UV lamp, meaning the UV lamp won't affect the user's ability to retrieve tableware, and the user is less likely to damage the UV lamp during this process. However, during tableware sterilization, a significant portion of the UV light emitted by the lamp inevitably needs to be reflected and attenuated on the rear wall of the cabinet before reaching the tableware. The tableware receives relatively little direct UV light, thus requiring a longer sterilization time to ensure effective sterilization, increasing the sterilizer's energy consumption. Summary of the Invention

[0003] Therefore, it is necessary to provide a disinfection cabinet that addresses the issue of high energy consumption.

[0004] A disinfection cabinet includes:

[0005] Inner liner;

[0006] A first drawer is movably disposed on the inner liner in a first direction to allow the first drawer to approach or move away from the rear sidewall of the inner liner;

[0007] The first rack is fixed to the first drawer;

[0008] The first gear is rotatably mounted on the inner liner and meshes with the first rack.

[0009] A drive motor, wherein the drive motor transmits power to the first gear;

[0010] An ultraviolet lamp, wherein the ultraviolet lamp is movably disposed on the inner liner along a first direction;

[0011] The second gear is rotatably mounted on the inner liner;

[0012] The second rack, wherein the ultraviolet lamp is fixed to the second rack, and the second gear meshes with the second rack;

[0013] The disinfection cabinet has a first state and a second state;

[0014] When the disinfection cabinet is in the first state, the distance between the first drawer and the rear side wall of the inner liner is d1, the distance between the ultraviolet lamp and the rear side wall of the inner liner is d2, and the first rack and the second gear are meshed.

[0015] When the disinfection cabinet is in the second state, the distance between the first drawer and the rear side wall of the inner liner is d3, the distance between the ultraviolet lamp and the rear side wall of the inner liner is d4, and the first rack and the second gear are spaced apart in the first direction;

[0016] Where d1 < d3, d2 > d4.

[0017] The beneficial effects of this invention are as follows:

[0018] When the sterilizer is in its first state, the first drawer is closed and rests against the rear wall of the inner liner, or the gap between the first drawer and the rear wall of the inner liner is very small, allowing the first rack to engage with the second gear. Simultaneously, there is a larger gap between the UV lamp and the rear wall of the inner liner, so less of the UV light emitted by the lamp is reflected by the rear wall and instead shines directly into the first drawer. This results in better sterilization of the tableware inside the first drawer, allowing for a reduction in sterilization time and lower power consumption of the sterilizer.

[0019] When the sterilizer is in the second state, the first drawer is open. At this time, the ultraviolet lamp is closer to the back wall of the inner liner, while the first drawer is farther away from the back wall of the inner liner. This results in a larger gap between the ultraviolet lamp and the first drawer, thereby reducing interference between the ultraviolet lamp and the tableware in the first drawer.

[0020] When the sterilizer is in its second state, the first rack and the second gear are spaced apart in the first direction, allowing the first drawer a certain amount of room to move. This way, even if the user accidentally pushes the first drawer while taking out or putting in tableware, the first rack will not easily engage the second gear, thus preventing the UV lamp from getting too close to the first drawer and maintaining low interference from the UV lamp on the tableware inside the first drawer.

[0021] When the disinfection cabinet is in the first state, the drive motor controls the first gear to rotate forward, which moves the first drawer and the first rack outward from the inner liner. At the same time, the first rack also drives the ultraviolet lamp and the second rack to move towards the rear wall of the inner liner through the second gear. After the ultraviolet lamp and the second rack are in place, the first gear continues to rotate forward, and the first drawer and the first rack continue to move outward from the inner liner. However, the first rack has now separated from the second gear, so the ultraviolet lamp and the second rack will not continue to move towards the rear wall of the inner liner. When the first drawer is fully opened, the first gear stops rotating, and the disinfection cabinet switches to the second state.

[0022] Conversely, when the disinfection cabinet is in the second state, the drive motor controls the first gear to reverse, causing the first drawer and the first rack to move towards the rear of the inner liner. Once the first rack and the second gear engage, the first gear continues to reverse, and the first drawer and the first rack continue to move towards the rear of the inner liner. At the same time, the first rack also drives the ultraviolet lamp and the second rack towards the front of the inner liner via the second gear, until the first drawer is fully closed, thus switching the disinfection cabinet to the first state.

[0023] The aforementioned switching structure effectively solves the problem of inconsistent travel distances between the first drawer and the UV lamp.

[0024] In some embodiments of this application, when the disinfection cabinet is in the first state, the openings of the ultraviolet lamp and the inner liner are spaced apart.

[0025] This reduces the reflection of ultraviolet light emitted by the UV lamp by the door of the first drawer, making it easier for the UV light emitted by the UV lamp to directly enter the first drawer.

[0026] In some embodiments of this application, the disinfection cabinet further includes an outer shell, the inner liner is disposed inside the outer shell, and the drive motor is located between the outer shell and the inner liner.

[0027] This reduces the space occupied by the drive motor inside the inner tank.

[0028] In some embodiments of this application, the first drawer is located above the ultraviolet lamp.

[0029] When the sterilizer is in its first state, the ultraviolet light generated by the ultraviolet lamp can penetrate through the gap at the bottom of the first drawer and enter the interior of the first drawer, thus directly sterilizing the tableware inside. When the sterilizer is in its second state, if tableware falls from the first drawer, it is less likely to come into contact with the ultraviolet lamp, reducing the possibility of the ultraviolet lamp being damaged.

[0030] In some embodiments of this application, the disinfection cabinet further includes a second drawer, which is movably disposed on the inner liner along a first direction and is located below the ultraviolet lamp.

[0031] When the sterilizer is in its first state, the ultraviolet light emitted by the UV lamp can shine more directly onto the top opening of the second drawer, thereby improving the sterilization effect of the tableware in the second drawer.

[0032] In some embodiments of this application, the first drawer includes a pull-out basket and a drawer frame fixed around the pull-out basket. One of the drawer frame and the inner wall of the inner liner is provided with a first guide rail extending in a first direction, and the other is provided with a first slider. The first slider is slidably disposed at the first guide rail, and the first rack is fixed to the bottom of the drawer frame.

[0033] The first toothed bar is fixed to the bottom of the drawer rack. This serves two purposes: firstly, given the limited width of the inner liner, it prevents the first toothed bar from occupying internal space in the width direction of the inner liner, allowing the first drawer to maintain a larger width and thus be able to hold more tableware; secondly, it minimizes the blocking effect of the first toothed bar on the ultraviolet light at the bottom of the pull-out basket.

[0034] In some embodiments of this application, the first rack is located above the first gear and the second gear.

[0035] When the first gear and the second gear mesh with the first rack, the meshing state is more stable under the gravity of the first drawer.

[0036] In some embodiments of this application, the inner wall of the inner liner is provided with a second guide rail, the end of the ultraviolet lamp is disposed on the second rack, and the second rack is slidably disposed on the second guide rail along a first direction.

[0037] This way, the movement direction of the ultraviolet lamp can be limited to the first direction, and the obstruction of ultraviolet light by the second rack and the second guide rail can be reduced.

[0038] In some embodiments of this application, the second guide rail is provided with a first clearance hole extending in a first direction, and the second rack is provided with a wiring hole, the wiring hole being connected to the first clearance hole.

[0039] As the UV lamp moves along the first direction, the wiring at the end of the UV lamp can always pass through the wiring hole at the first clearance hole, and then connect to the control board on the outside of the inner liner. The second guide rail can avoid obstructing the UV lamp's wiring during its movement through the first clearance hole.

[0040] In some embodiments of this application, a second clearance hole extending in a first direction is provided on the inner liner sidewall, the first clearance hole is connected to the second clearance hole, and the second rack at least partially covers the first clearance hole.

[0041] The UV lamp tip wiring can pass through the inner liner sidewall via the first and second clearance holes. Since the second rack extends along the first direction, the portion of the first clearance hole except for the wiring section can be blocked by the second rack, thereby maintaining the airtightness of the inner liner.

[0058] Example:

[0059] like Figures 1-8 As shown, this embodiment provides a disinfection cabinet, including an inner liner 1, a first drawer 2, an ultraviolet lamp 5, and an outer shell 8. The inner liner 1 is disposed inside the outer shell 8. The first drawer 2 is movably disposed on the inner liner 1 along a first direction, allowing the first drawer 2 to approach or move away from the rear side wall of the inner liner 1; in other words, the first direction is the depth direction of the inner liner 1. The ultraviolet lamp 5 is mounted on the inner liner 1 for disinfecting the tableware inside the first drawer 2.

[0060] The disinfection cabinet in this embodiment also includes a drive motor, a first rack 3, a first gear 4, a second gear 6, and a second rack 7.

[0061] The first rack 3 is fixed to the first drawer 2 and extends along the first direction. The first gear 4 is rotatably mounted on the inner liner 1 and meshes with the first rack 3, driving the motor to transmit power to the first gear 4. The drive motor controls the rotation of the first gear 4 on the inner liner 1, thereby driving the first rack 3 and the first drawer 2 to move along the first direction on the inner liner 1, thus opening and closing the first drawer 2 for the user to conveniently take out and put away tableware.

[0062] An ultraviolet lamp 5 is movably mounted on the inner liner 1 along a first direction, and a second rack 7 also extends along the first direction, with the ultraviolet lamp 5 fixed to the second rack 7. A second gear 6 is rotatably mounted on the inner liner 1 and meshes with the second rack 7. During rotation, the second gear 6 can control the movement of the ultraviolet lamp 5 in the first direction via the second rack 7.

[0063] The disinfection cabinet has a first state and a second state.

[0064] Specifically, such as Figures 1-3As shown, when the disinfection cabinet is in the first state, the first drawer 2 is closed, and the door of the first drawer 2 seals the opening of the inner liner 1. The distance between the first drawer 2 and the rear wall of the inner liner 1 is d1, where d1 ≥ 0. In other words, the first drawer 2 is in contact with the rear wall of the inner liner 1, or the distance between the first drawer 2 and the rear wall of the inner liner 1 is very small, allowing the first rack 3 to contact and mesh with the second gear 6. Simultaneously, the distance between the ultraviolet lamp 5 and the rear wall of the inner liner 1 is d2, where d2 > 0. This means there is a large distance between the ultraviolet lamp 5 and the rear wall of the inner liner 1, resulting in less reflection of the ultraviolet light emitted by the ultraviolet lamp 5 by the rear wall of the inner liner 1, and more direct penetration into the first drawer 2. This leads to better disinfection of the tableware inside the first drawer 2, allowing for a reduction in disinfection time and lower power consumption of the disinfection cabinet.

[0065] For example, the first drawer 2 includes a pull-out basket 21, a drawer frame 22 fixed around the pull-out basket 21, and the door panel fixed to the drawer frame 22.

[0066] In this embodiment, the first drawer 2 is located above the ultraviolet lamp 5. When the disinfection cabinet is in the first state, the ultraviolet light generated by the ultraviolet lamp 5 can enter the interior of the pull basket 21 through the gap at the bottom of the pull basket 21, thereby directly disinfecting the tableware in the pull basket 21.

[0067] In some other embodiments, the ultraviolet lamp 5 can be located above the first drawer 2, so that when the disinfection cabinet is in the first state, the ultraviolet light generated by the ultraviolet lamp 5 can directly enter the first drawer 2 through the opening of the first drawer 2, thereby directly disinfecting the tableware in the pull-out basket 21.

[0068] In a further preferred embodiment, when the disinfection cabinet is in the first state, the openings of the ultraviolet lamp 5 and the inner liner 1 are spaced apart. This reduces the reflection of ultraviolet light emitted by the ultraviolet lamp 5 by the door panel of the first drawer 2, and facilitates the direct entry of ultraviolet light emitted by the ultraviolet lamp 5 into the first drawer 2.

[0069] Specifically, such as Figures 4-6 As shown, when the disinfection cabinet is in the second state, the first drawer 2 is open. At this time, the distance between the first drawer 2 and the rear wall of the inner liner 1 is d3, and the distance between the ultraviolet lamp 5 and the rear wall of the inner liner 1 is d4, where d3 > d1 and d2 > d4. In other words, the ultraviolet lamp 5 is closer to the rear wall of the inner liner 1, while the first drawer 2 is farther away from the rear wall of the inner liner 1. This results in a larger distance between the ultraviolet lamp 5 and the first drawer 2, thereby reducing interference between the ultraviolet lamp 5 and the tableware inside the first drawer 2.

[0070] Specifically in this embodiment, the first drawer 2 is located above the ultraviolet lamp 5. When the disinfection cabinet is in the second state, if the tableware in the first drawer 2 falls, the fallen tableware is less likely to come into contact with the ultraviolet lamp 5, thus reducing the occurrence of damage to the ultraviolet lamp 5.

[0071] In some other embodiments, the first drawer 2 is located below the ultraviolet lamp 5. When the disinfection cabinet is in the second state, the ultraviolet lamp 5 located on the rear side wall of the inner liner 1 is less likely to block the top opening of the first drawer 2 located on the front side of the inner liner 1. This can reduce the interference of the ultraviolet lamp 5 with the user's actions of taking tableware out of the first drawer 2.

[0072] More notably, when the sterilizer is in its second state, the first rack 3 and the second gear 6 are spaced apart in the first direction, thus providing the first drawer 2 with a certain amount of room to maneuver. This way, even if the user accidentally pushes the first drawer 2 while taking out or putting in tableware, the first rack 3 will not easily drive the second gear 6, thereby preventing the ultraviolet lamp 5 from getting close to the first drawer 2 and maintaining low interference from the ultraviolet lamp 5 to the tableware inside the first drawer 2.

[0073] In this embodiment, the first gear 4 is rotated by a drive motor, which allows the disinfection cabinet to switch between the first state and the second state.

[0074] When the disinfection cabinet is in the first state, the drive motor controls the first gear 4 to rotate forward, which causes the first drawer 2 and the first rack 3 to move outward from the inner liner 1. At the same time, the first rack 3 also drives the ultraviolet lamp 5 and the second rack 7 to move towards the rear wall of the inner liner 1 through the second gear 6. After the ultraviolet lamp 5 and the second rack 7 have moved into place, the first gear 4 continues to rotate forward, and the first drawer 2 and the first rack 3 continue to move outward from the inner liner 1. However, the first rack 3 has now separated from the second gear 6, so the ultraviolet lamp 5 and the second rack 7 will not continue to move towards the rear wall of the inner liner 1. When the first drawer 2 is fully opened, the first gear 4 stops rotating, and the disinfection cabinet switches to the second state.

[0075] Conversely, when the disinfection cabinet is in the second state, the drive motor controls the first gear 4 to reverse, causing the first drawer 2 and the first rack 3 to move towards the rear of the inner liner 1. After the first rack 3 and the second gear 6 contact and mesh, the first gear 4 continues to reverse, and the first drawer 2 and the first rack 3 continue to move towards the rear of the inner liner 1. At the same time, the first rack 3 also drives the ultraviolet lamp 5 and the second rack 7 to move towards the center of the inner liner 1 through the second gear 6, until the first drawer 2 is completely closed, thus switching the disinfection cabinet to the first state.

[0076] The aforementioned switching structure effectively solves the problem of inconsistent travel distances between the first drawer 2 and the ultraviolet lamp 5.

[0077] Preferably, in this embodiment, the drive motor is located between the outer shell 8 and the inner liner 1 to reduce the space occupied by the drive motor inside the inner liner 1.

[0078] This embodiment of the disinfection cabinet also includes a second drawer 9, which is movably mounted on the inner liner 1 along a first direction and is located below the ultraviolet lamp 5. Thus, when the disinfection cabinet is in the first state, the light emitted by the ultraviolet lamp 5 can shine more directly onto the top opening of the second drawer 9, thereby improving the disinfection effect of the tableware inside the second drawer 9.

[0079] like Figure 3 As shown, one of the drawer frame 22 and the inner wall of the inner liner 1 is provided with a first guide rail 11 extending in a first direction, and the other is provided with a first slider 221, which is slidably disposed at the first guide rail 11. Through the cooperation of the first slider 221 and the first guide rail 11, the movement direction of the first drawer 2 is restricted to the first direction.

[0080] In addition, in this embodiment, the first toothed rack 3 is fixed to the bottom of the drawer frame 22. On the one hand, given the limited width of the inner liner 1, the first toothed rack 3 is prevented from occupying the internal space of the inner liner 1 in the width direction, which helps the first drawer 2 to maintain a larger width, thereby accommodating more tableware. On the other hand, the first toothed rack 3 can minimize the blocking effect of ultraviolet light on the bottom of the pull-out basket 21.

[0081] Preferably, in this embodiment, the first rack 3 is located above the first gear 4 and the second gear 6. In this way, when the first gear 4 and the second gear 6 mesh with the first rack 3, the meshing state can be more stable under the gravity of the first drawer 2.

[0082] like Figure 7 and Figure 8 As shown, a second guide rail 12 is provided on the inner wall of the inner liner 1, and the end of the ultraviolet lamp 5 is mounted on the second rack 7. The second rack 7 is slidably mounted on the second guide rail 12 along the first direction. In this way, the movement direction of the ultraviolet lamp 5 can be restricted to the first direction, and the obstruction of ultraviolet light by the second rack 7 and the second guide rail 12 can be reduced.

[0083] Based on this, the second guide rail 12 has a first clearance hole 121 extending along the first direction, and the second rack 7 has a wiring hole 71 connected to the first clearance hole 121. During the movement of the UV lamp 5 along the first direction, the wiring at the end of the UV lamp 5 can always pass through the wiring hole 71 at the first clearance hole 121, and then connect to the control board on the outside of the inner liner 1. The second guide rail 12 can avoid obstructing the wiring of the UV lamp 5 during its movement through the first clearance hole 121.

[0084] To allow the wiring at the end of the UV lamp 5 to pass through the side wall of the inner liner 1, a second clearance hole is provided on the side wall of the inner liner 1, and the first clearance hole 121 communicates with the second clearance hole. To accommodate the wiring during the movement of the UV lamp 5, the second clearance hole also extends along the first direction. During the movement of the UV lamp 5, because the second rack 7 extends along the first direction, the portion of the first clearance hole 121 except for the wiring section can be blocked by the second rack 7, thereby maintaining the airtightness of the inner liner 1.

[0085] In some embodiments, the drive motor can be controlled by a voice module, which is electrically connected to 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 drive motor to perform corresponding operations, thereby opening and closing the first drawer 2 and improving the user experience.

[0086] 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.

[0087] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
