Description

Technical Field

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

[0002] A sterilizing cabinet is a household appliance used to disinfect tableware, kitchen utensils, etc. It can effectively kill bacteria and viruses, ensuring food safety and hygiene. Sterilizing cabinets are equipped with pull-out baskets for storing tableware and kitchen utensils, and also allow the tableware to drain.

[0003] In related technologies, most of the pull-out baskets in disinfection cabinets are manually pulled out, which cannot meet the requirement of automatic extension and retraction of the baskets, thus affecting the user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a disinfection cabinet that automates the extension and retraction of the pull-out basket, thereby enhancing the user experience.

[0005] The disinfection cabinet includes a cabinet body, a movable pull-out basket disposed in the cabinet body, a support base, and a drive mechanism; the support base is slidably connected to the cabinet body and connected to the pull-out basket; the drive mechanism includes a transmission wheel and a connecting rod, the connecting rod being movably connected between the cabinet body and the support base, one of the connecting rod and the transmission wheel having a guide channel, and the other having a guide post, the guide post being inserted into the guide channel; wherein, the transmission wheel is rotatable about its own axis, and the guide post is configured to move within the guide channel in response to the rotation of the transmission wheel, so as to drive the connecting rod to move the support base along a first direction, and the pull-out basket moves synchronously with the support base.

[0006] Understandably, the drive wheel transmits power to the connecting rod, which, through the cooperation of the guide post and the guide channel, can move smoothly along the trajectory of the guide channel. In other words, the guide channel guides and limits the movement of the guide post. The connecting rod can then transmit power to the support base. Since the support base is slidably connected to the cabinet, it supports the pull-out basket while simultaneously causing the basket to automatically extend and retract relative to the cabinet, thus achieving automation.

[0007] In some embodiments, one end of the connecting rod is rotatably connected to the cabinet and the other end is rotatably connected to the support base, and at least a portion of the guide channel is arc-shaped.

[0008] Understandably, the cabinet provides support for the rotation of the connecting rod, and the connecting rod is rotatably connected to the support base, facilitating the flexible movement of the support base. At least part of the guide channel is arc-shaped, which helps reduce the frictional force on the guide column as it moves within the guide channel, making its movement smoother.

[0009] In some embodiments, the guide channel includes an arc segment and a straight segment, with at least one end of the arc segment connected to the straight segment along its own extension direction.

[0010] It is understandable that, compared to the curved section, the guide column experiences greater friction when moving in the straight section, causing it to decelerate relative to the curved section. The straight section, serving as the starting and / or ending point of the guide column's movement, can improve the smoothness of the basket's movement at the beginning and / or end of the extension / retraction.

[0011] In some embodiments, the connecting rod includes a first rod body and a second rod body, which are hinged together. The first rod body is rotatably connected to the cabinet, and the second rod body is rotatably connected to the support base. The guide channel is provided on the first rod body.

[0012] Understandably, the second rod extends the lever arm to transmit the power of the first rod to the support, thus saving effort.

[0013] In some embodiments, the cabinet includes an inner liner and an outer shell covering the outside of the inner liner; the pull-out basket is disposed in the inner liner, the inner liner has a mounting hole extending through its own thickness, the support seat passes through the mounting hole and is movable within the mounting hole, and the drive wheel and the connecting rod are both disposed on the outside of the inner liner.

[0014] Understandably, the design of the inner liner and outer shell enhances the cabinet's strength, providing better protection for the interior. The pull-out basket is positioned within the inner liner, while the drive wheel and connecting rod are located outside, preventing interference with the basket's extension and retraction. Mounting holes on the inner liner allow the support base to slide relative to the cabinet, providing a guiding and limiting function for the support base.

[0015] In some embodiments, a cavity is provided between the inner liner and the outer shell, and the drive wheel and the connecting rod are disposed in the cavity; or, the drive mechanism further includes a protective cover, which covers the drive wheel and the connecting rod on the side away from the inner liner.

[0016] Understandably, the sandwich cavity provides assembly space for the drive wheel and connecting rod, which helps protect their structure. Alternatively, the protective cover may also serve a protective and dustproof function.

[0017] In some embodiments, the support base is provided with a limiting portion that can abut against the inner liner to restrict the movement of the support base in a second direction.

[0018] Understandably, the limiting part can restrict the movement of the support seat in the second direction, preventing the basket from swaying in the second direction.

[0019] In some embodiments, the drive mechanism further includes a power source connected to the transmission wheel for driving the transmission wheel to rotate.

[0020] Understandably, the power source provides the power for the automatic extension and retraction of the basket.

[0021] In some embodiments, the transmission wheel has a plurality of circumferentially spaced teeth; the drive mechanism further includes a transmission gear connected to the power source and engaging with the transmission wheel through the plurality of teeth; wherein the tooth diameter of the transmission gear is smaller than the tooth diameter of the transmission wheel.

[0022] It is understandable that the tooth meshing transmission method has high transmission efficiency, and by setting the tooth diameter of the transmission gear to be smaller than that of the transmission wheel, speed reduction is achieved, thereby improving the smoothness of the basket movement.

[0023] In some embodiments, the power source and the transmission wheel are arranged on opposite sides along the thickness direction of the cabinet.

[0024] Understandably, this design reduces interference with the movement of the pull-out basket while minimizing the space occupied by the disinfection cabinet, making it more aesthetically pleasing. Attached Figure Description

[0037] It should also be understood that the terms “including / comprise” or “have” specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0038] Please see Figures 1 to 4 This application provides a disinfection cabinet 100, which includes a cabinet body 10, a movable pull-out basket 20 disposed on the cabinet body 10, a support base 30, and a drive mechanism 40. The support base 30 is slidably connected to the cabinet body 10 and connected to the pull-out basket 20. Thus, the cabinet body 10 provides support and assembly space for the pull-out basket 20, the support base 30, and the drive mechanism 40. The drive mechanism 40 can transmit power to the support base 30, which, while providing support for the pull-out basket 20, drives the pull-out basket 20 to move, thereby realizing the automatic extension and retraction of the pull-out basket 20.

[0039] like Figures 1 to 3 As shown, the drive mechanism 40 further includes a transmission wheel 41 and a connecting rod 42. The connecting rod 42 is movably connected between the cabinet 10 and the support base 30. One of the connecting rod 42 and the transmission wheel 41 is provided with a guide channel 51, and the other is provided with a guide post 52, which is inserted into the guide channel 51. The transmission wheel 41 can rotate around its own axis, and the guide post 52 is configured to move within the guide channel 51 in response to the rotation of the transmission wheel 41, thereby driving the connecting rod 42 to move the support base 30 in a first direction, and the pull-out basket 20 moves synchronously with the support base 30.

[0040] In other words, when the transmission wheel 41 rotates, the guide post 52 and the guide channel 51 work together to allow the guide post 52 to move along the guide channel 51, thereby transmitting the power of the transmission wheel 41 to the connecting rod 42, which in turn transmits the power to the support seat 30. The guide channel 51 guides and limits the movement of the guide post 52, ensuring smooth power transmission and improving the stability of the connecting rod 42's movement.

[0041] For example, the connecting rod 42 is provided with a guide channel 51, and the transmission wheel 41 is provided with a guide post 52; or, the connecting rod 42 is provided with a guide post 52, and the transmission wheel 41 is provided with a guide channel 51.

[0042] In summary, the transmission wheel 41, connecting rod 42, and support base 30 can transmit power to the pull-out basket 20 layer by layer, thereby realizing the automatic extension and retraction of the pull-out basket 20 to enhance the user experience. Furthermore, the cooperation between the guide channel 51 and the guide column 52 helps to enhance the stability of the movement of the pull-out basket 20.

[0043] For ease of explanation, let's take a cube-shaped cabinet 10 as an example. The width direction of cabinet 10 is the first direction, the length direction is the second direction, the first direction is the x-axis, the second direction is the y-axis, and the height direction is the z-axis.

[0044] like Figure 4 As shown, in an optional embodiment, the drive mechanism 40 further includes a power source 60 connected to the transmission wheel 41 to provide power to the transmission wheel 41 for driving the transmission wheel 41 to rotate. For example, the power source 60 can be a stepper motor, which helps to enhance damping, promote the smoothness of the pull-out basket 20's movement, and reduce noise when the pull-out basket 20 is closed.

[0045] like Figures 1 to 3 As shown, in a further embodiment, the transmission wheel 41 is provided with a plurality of circumferentially spaced teeth; the drive mechanism 40 also includes a transmission gear 43, which is connected to the power source 60 and engages with the transmission wheel 41 through the meshing of the plurality of teeth. Thus, the power source 60 first transmits power to the transmission gear 43, which then transmits power to the transmission wheel 41. The transmission wheel 41, by having teeth meshing with the transmission gear 43, facilitates efficient power transmission, resulting in a simple structure and easy operation.

[0046] In a specific embodiment, the tooth diameter of the transmission gear 43 is smaller than that of the transmission wheel 41, which helps to reduce the rotational speed of the transmission wheel 41, promotes the smooth transmission of power, and improves the smoothness of the movement of the basket 20.

[0047] like Figures 1 to 3As shown, in a further embodiment, one end of the connecting rod 42 is rotatably connected to the cabinet 10, and the other end is rotatably connected to the support base 30. Thus, the transmission wheel 41 drives the connecting rod 42 to rotate relative to the cabinet 10, and the connecting rod 42 continues to transmit power to the support base 30, causing the support base 30 to move. The support base 30 can rotate relative to the connecting rod 42 during movement, improving transmission flexibility.

[0048] like Figures 1 to 3 As shown, in an optional embodiment, at least a portion of the guide channel 51 is arc-shaped to form a smooth arc surface, which helps to reduce friction when the guide post 52 moves, promotes the smooth operation of the guide post 52 in the guide channel 51, and improves the smoothness of the pull basket 20 movement.

[0049] like Figure 2 As shown, in a specific embodiment, the guide channel 51 includes an arc-shaped section 511 and a straight section 512. The arc-shaped section 511 can reduce the friction when the guide post 52 moves, while the straight section 512 has a greater frictional effect on the movement of the guide post 52 than the arc-shaped section 511, so that the speed at which the guide post 52 moves in the straight section 512 is less than that in the arc-shaped section 511.

[0050] Furthermore, at least one end of the arc-shaped segment 511 along its extension direction is connected to a straight segment 512. Taking the example that both ends of the arc-shaped segment 511 along its extension direction are connected to straight segments 512, this arrangement makes the straight segments 512 serve as the starting and ending points of the guide column 52's movement, which corresponds to the starting and ending points of one movement of the pull-out basket 20. In this way, the speed of the pull-out basket 20 when moving at the starting and ending points is relatively slow, enhancing the damping sensation, avoiding the impact on the cabinet 10 caused by the pull-out basket 20 suddenly opening or closing, and reducing the noise when the pull-out basket 20 opens and closes.

[0051] like Figure 3 As shown, in a specific embodiment, the length of the straight section 512 is 'a', and the length of the arc-shaped section 511 is 'b', where 0.08b ≤ a ≤ 0.15b. This ensures that the arc-shaped section 511 has sufficient length to provide a smooth feel during the extension and retraction of the pull-out basket 20, and also prevents the straight section 512 from being too short, ensuring a buffering effect on the start and stop of the pull-out basket 20's movement, thus ensuring stability. For example, a = 0.08b, 0.1b, or 0.15b.

[0052] In a specific embodiment, the guide channel 51 can be configured as a guide groove or a guide hole, both of which can limit and guide the guide post 52.

[0053] like Figures 1 to 3As shown, in a specific embodiment, the connecting rod 42 includes a first rod body 421 and a second rod body 422, which are hinged together. The first rod body 421 is rotatably connected to the cabinet 10, and the second rod body 422 is rotatably connected to the support base 30. A guide channel 51 is provided on the first rod body 421, and correspondingly, the transmission wheel 41 is provided with a guide post 52. The transmission wheel 41 transmits power to the first rod body 421, which rotates relative to the cabinet 10 and transmits power to the second rod body 422, which then transmits the power to the support base 30. The second rod body 422 acts as an extension of the lever arm, allowing the support base 30 to move with a smaller amount of power.

[0054] In an optional embodiment, the cabinet 10 includes an inner liner 11 and an outer shell covering the outside of the inner liner 11. The double-layered design of the inner liner 11 and the outer shell enhances the strength of the cabinet 10, protecting the parts and kitchen utensils inside the inner liner 11. Furthermore, a pull-out basket 20 is disposed within the inner liner 11. The inner liner 11 has a mounting hole 111 extending along its thickness. A support base 30 passes through the mounting hole 111 and can move within it. The wall of the mounting hole 111 limits and guides the support base 30, allowing it to move along the wall of the mounting hole 111, thus improving the stability of the pull-out basket 20 driven by the support base 30. In a specific embodiment, the support base 30 is connected to the bottom of the pull-out basket 20 to increase the contact area with the basket 20 and improve the support effect.

[0055] like Figures 1 to 3 As shown, in an optional embodiment, both the drive wheel 41 and the connecting rod 42 are located on the outside of the inner liner 11 to avoid interfering with the movement of the pull-out basket 20 relative to the cabinet 10. Simultaneously, since the kitchen utensils in the pull-out basket 20 will drain through it, this arrangement also prevents water droplets from adversely affecting the drive wheel 41 and the connecting rod 42.

[0056] like Figure 2 As shown, in a further embodiment, the support base 30 is provided with a limiting part 31, which can abut against the inner liner 11 to restrict the movement of the support base 30 in the second direction, prevent the support base 30 from shaking in the second direction, and make the support base 30 move only along the hole wall of the assembly hole 111, thereby improving the stability of the support base 30 driving the pull basket 20 to move.

[0057] In some embodiments, a sandwich cavity is provided between the inner liner 11 and the outer shell, and the transmission wheel 41 and the connecting rod 42 are located in the sandwich cavity. The sandwich cavity is provided to reduce the use of materials, and the outer shell can protect the structure of the transmission wheel 41 and the connecting rod 42 and play a shielding role, so that the disinfection cabinet 100 has an aesthetic appearance.

[0058] like Figure 4As shown, in some other embodiments, the drive mechanism 40 also includes a protective cover 44, which covers the transmission wheel 41 and the connecting rod 42 on the side away from the inner liner 11. The protective cover 44 can also protect the transmission wheel 41 and the connecting rod 42 and has an aesthetic effect.

[0059] like Figures 1 to 4 As shown, in a further embodiment, the power source 60 and the transmission wheel 41 are arranged on opposite sides along the thickness direction of the cabinet 10, that is, the power source 60 is set in the inner liner 11 to reduce the occupation of external space and make the disinfection cabinet 100 more aesthetically pleasing. The influence of dripping water from kitchen utensils can be prevented by covering the outside of the power source 60 with a protective shell.

[0060] 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.

[0061] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but 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.
