[0001] The present invention relates to the technical field related to sterilization and disinfection equipment, and in particular to a sterilization machine and a sterilization method. Background Art

[0002] As people continue to pay more attention to healthy eating, chopping boards that come into direct contact with food have been found to be very prone to harboring dirt and grime, or breeding bacteria, mold, parasites, etc. This is because chopping boards are difficult to clean thoroughly. At the same time, due to the high humidity in the kitchen, chopping boards are often difficult to keep dry for a long time and are prone to breeding bacteria. The next time you use the chopping board to cut vegetables, the bacteria grown on the chopping board will spread to the food, which may cause potential health problems.

[0003] To address this issue, existing technologies have developed sterilization and disinfection devices capable of sterilizing cutting boards, knives, and the like. These devices typically utilize hot air sterilization and ultraviolet light to sterilize cutting boards and knives. However, existing sterilization and disinfection devices are limited in the size of cutting boards they can accommodate and are not suitable for round or other shaped cutting boards, resulting in poor versatility. Furthermore, the ultraviolet light is typically fixed to the inner wall of the housing, preventing it from disinfecting areas of the cutting board that are obscured by objects such as knives, resulting in incomplete disinfection and a reduced effectiveness of the sterilization process. Summary of the Invention

[0028] As a preferred technical solution of the above sterilization method, after the step of placing the cutting board to be cleaned into the placement slot, it also includes starting hot air sterilization.

[0029] The technical solution of the present invention has the following advantages:

[0030] (1) The sterilizing machine provided by the present invention includes a housing, a placement rack, and a movable shell. A sterilizing mechanism is provided inside the housing. The placement rack is provided on one side of the housing and is connected to the interior of the housing. The placement rack is provided with a placement slot for placing a cutting board. The movable shell is provided at both ends of the placement slot. The movable shell has a storage state in which it is placed in the placement slot and an expanded state in which it extends out of the placement slot. When the cutting board to be sterilized is relatively large or has an irregular shape, the movable shell can be opened to be in the expanded state, thereby increasing the size of the placement slot. This allows the sterilizing machine to adapt to cutting boards of more sizes and shapes, and has strong versatility, thereby meeting the different usage needs of users.

[0031] (2) In the sterilizer provided by the present invention, the bottom of the movable shell is hingedly connected to the inner wall of the placement slot. The movable shell includes two side panels, and the outer walls of the side panels are slidably connected to the inner wall of the placement slot via a limiting mechanism. The limiting mechanism can limit the movable shell in a folded state or an unfolded state and prevent the movable shell from falling out of the placement slot, thereby affecting its normal use.

[0032] (3) The sterilizing machine provided by the present invention further includes an outer cover body, which is suitable for covering the placement groove. When the cutting board is sterilized, the cutting board to be sterilized placed in the placement groove can be enclosed in the outer cover body, thereby enhancing the sterilization and disinfection effect. Preferably, part of the edge of the outer cover body is detachably connected to the movable shell to improve the firmness of the connection of the outer cover body and prevent the outer cover body from falling off during the sterilization process.

[0033] (4) The sterilizer provided by the present invention has at least two tool placement positions on the shell, and the at least two tool placement positions are arranged in a stepped manner, which conforms to the ergonomic design and is more convenient for users to place the tools for sterilization and disinfection.

[0034] (5) The sterilizing mechanism provided by the present invention includes an ultraviolet sterilizing mechanism, which includes a traveling track and an ultraviolet lamp. The traveling track is disposed within the housing, and the ultraviolet lamp is movable along the traveling track.

[0035] (6) The sterilizer provided by the present invention has a plurality of sterilization points disposed on a traveling track. A pneumatic structure is provided on the traveling track to drive the ultraviolet lamp to move between the sterilization points. This design enhances the controllability of the ultraviolet lamp's movement, allowing it to move stably and reliably on the traveling track, ensuring effective sterilization and disinfection.

[0036] (7) In the sterilization machine provided by the present invention, each sterilization point is also provided with a magnet for absorbing the ultraviolet lamp. Since the outer shell of the ultraviolet lamp can be absorbed by the magnet, the sterilization point can quickly capture the ultraviolet lamp, thereby improving the accuracy of the movement position of the ultraviolet lamp.

[0037] (8) The sterilization method provided by the present invention includes: placing the cutting board to be sterilized in a placement slot; starting ultraviolet sterilization; turning on the ultraviolet lamp, and driving the ultraviolet lamp to move to each sterilization point on a patrol track in sequence and stay at each sterilization point for a time t until the ultraviolet lamp returns to its initial position; and ending the ultraviolet sterilization. The above sterilization method can achieve comprehensive sterilization and disinfection of the cutting board, significantly improve the sterilization effect, and enhance the user experience.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0050] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0051] like Figure 1 、 2 The figure shows a preferred embodiment of the sterilizer of the present invention. This sterilizer is used to sterilize kitchen utensils such as cutting boards, knives, and chopsticks. It is adaptable to cutting boards of various sizes and shapes, offering high versatility and meeting the diverse needs of users. Furthermore, it can sterilize cutting boards in all directions, achieving effective sterilization and disinfection results and providing a good user experience.

[0052] This sterilizer includes a housing 1, a placement frame 2, and a movable shell 3. The interior of the housing 1 is provided with a sterilization mechanism. The interior of the housing 1 is a cavity with a certain volume, and the sterilization mechanism is arranged in the cavity. In this embodiment, the housing 1 is a rectangular parallelepiped structure suitable for placement on a desktop or countertop.

[0053] A storage rack 2 is disposed on one side of the housing 1 and communicates with the interior of the housing 1. A placement slot 201 for placing a cutting board is provided on the rack 2. In this embodiment, the rack 2 is also a rectangular parallelepiped structure. The placement slot 201 is formed along the length of the rack 2. The two ends of the placement slot 201 are connected, and the top of the placement slot 201 is open, making it easy to place and remove the cutting board. The rack 2 communicates with the interior of the housing 1. When the sterilization mechanism in the housing 1 is activated, the cutting board on the rack 2 can be sterilized and disinfected.

[0054] Movable shells 3 are positioned at both ends of slot 201. They can be placed in a stowed position, inserted into slot 201, or extended. When stowed, they maintain the normal use of slot 201. When extended, they extend slot 201, making it suitable for larger or more shaped cutting boards, broadening its applicability and meeting diverse needs.

[0055] Furthermore, the bottom of the movable shell 3 is hingedly connected to the inner wall of the placement slot 201, facilitating its storage and deployment. The movable shell 3 includes two side panels 301, the outer walls of which are slidably connected to the inner wall of the placement slot 201 via a retaining mechanism. The two side panels 301 are positioned proximate to the inner wall of the placement slot 201. This retaining mechanism maintains the movable shell 3 in its stored or deployed state, preventing it from falling out of the placement slot 201 and effectively limiting its position.

[0056] Furthermore, the limiting mechanism includes a limiting groove and a limiting protrusion. The limiting groove is formed on one of the inner wall of the placement groove 201 and the outer wall of the side plate portion 301, and the limiting protrusion is provided on the other. In this embodiment, the limiting groove is formed on the inner wall of the placement groove 201, and the limiting protrusion is provided on the outer wall of the side plate portion 301. As the movable shell 3 moves, the limiting protrusion slides in the limiting groove, and the two ends of the limiting groove are closed. When the limiting protrusion contacts the inner end of the limiting groove, the movable shell 3 cannot be further retracted, and the movable shell 3 is now in the retracted state. Similarly, when the limiting protrusion contacts the outer end of the limiting groove, the movable shell 3 cannot be further extended, and the movable shell 3 is now in the extended state.

[0057] Furthermore, the movable shell 3 further includes a connecting portion 302, and the outer sides of the two side panels 301 are connected by the connecting portion 302. The two side panels 301 and the connecting portion 302 form a groove structure for cooperating with the placement groove 201 to place the cutting board together.

[0058] Further, such as Figure 3 As shown, in this embodiment, the side panels 301 are triangular in shape. When the movable shell 3 is in the stowed state, the outer edges of the side panels 301 are flush with the outer edges of the placement slot 201. When the movable shell 3 is in the deployed state, the outer edges of the side panels 301 form an acute angle with the outer edges of the placement slot 201. In this embodiment, when the movable shell 3 is in the stowed state, one corner of the side panels 301 of the two movable shells 3 is exactly opposite, thereby fully utilizing the installation space and maximizing the size of the movable shell 3, so that the sterilizer can be used for cutting boards of various sizes.

[0059] Furthermore, the sterilizing machine of this embodiment also includes an outer cover 4, which is suitable for covering the placement groove 201. When the cutting board that needs to be sterilized is relatively large or the sterilization effect needs to be enhanced, the outer cover 4 can be used to cover the placement groove 201 together with the cutting board. When sterilizing ordinary cutting boards in daily life, the outer cover 4 can be omitted. In this case, it is only necessary to store the outer cover 4. In this embodiment, the outer cover 4 is made of soft, retractable, and easy-to-store fabric, and the upper part of the outer cover 4 is a circular structure that can be used to cover the circular cutting board 10. Figure 4As shown, a portion of the edge of the outer cover 4 is detachably connected to the movable shell 3 to improve the secure installation of the outer cover 4, prevent the outer cover from falling off during the sterilization process, and enhance the sealing inside the outer cover 4 to provide a sterilization effect. Specifically, a portion of the edge of the outer cover 4 can be detachably connected to the movable shell 3 via a zipper 9, which is simple in structure and convenient for users to operate.

[0060] Furthermore, the housing 1 is provided with at least two tool placement positions 6, arranged in a stepped manner. This design conforms to ergonomics and makes it more convenient for users to place tools for sterilization and disinfection. Furthermore, to fully utilize the space and increase the functionality and use of the sterilizer, the housing 1 is also provided with a chopstick placement position 7 and a knife placement position 8. The chopstick placement position 7 is located at the bottom of the housing 1 and has an elliptical cross-sectional structure, allowing for the proper storage of scattered chopsticks and other items, similar to the principle of a rugby ball, and providing a larger area for exposure to ultraviolet light. Furthermore, the tool placement position 6 is used to place larger knives for cutting vegetables and meat, while the knife placement position 8 is used to place smaller knives, such as fruit knives. Once a tool is placed, the cavity structure secures the tip and handle of the tool. The knife placement position 8 is located to one side of the tool placement position 6. Knives placed in the knife placement position 8 and the tool placement position 6, as well as chopsticks placed in the chopstick placement position 7, are all placed within the cavity of the housing 1, allowing for hot air sterilization and ultraviolet sterilization.

[0061] Further, such as Figure 5 As shown, within the housing 1, the sterilization mechanism includes an ultraviolet sterilization mechanism, which includes a traveling track 5 and an ultraviolet lamp. The traveling track 5 is disposed within the housing 1, and the ultraviolet lamp can move along the traveling track 5. In this embodiment, the traveling track 5 is a three-dimensional grid track with a four-layer structure from bottom to top and a three-layer structure from left to right.

[0062] Furthermore, a plurality of sterilization points 501 are provided on the patrol track 5, and a pneumatic structure is provided on the patrol track 5 for driving the ultraviolet lamp to move between the sterilization points 501. Preferably, the distances between the sterilization points 501 are the same.

[0063] Specifically, the pneumatic structure includes a ventilation duct and an air source. The ventilation duct is formed within the patrol track 5, with the air inlet of the ventilation duct connected to the air source. The air outlet of the ventilation duct is formed on the patrol track 5 and located at each sterilization point 501. The patrol track 5 is hollow inside to form the ventilation duct. The air source can be an external gas supply bottle, for example. When the air source supplies air to the air outlet of a ventilation duct, the thrust of the gas can overcome the gravity and friction of the UV lamp, blowing up the UV lamp located at that outlet and moving it to the next sterilization point 501.

[0064] Furthermore, each sterilization point 501 is provided with a magnet for attracting the UV lamp. Since the UV lamp housing is made of iron or other materials, it can be attracted by the magnet. When the UV lamp is blown by the gas and moves to the next sterilization point 501, when the UV lamp approaches the next sterilization point 501, the magnet provided on it will accelerate the movement of the UV lamp, causing it to quickly reach the next sterilization point 501.

[0065] Furthermore, the roving track 5 is preferably an H-shaped track, with the UV lamp embedded within it. Each sterilization point 501 is also equipped with a power supply. When the UV lamp is stationed at that sterilization point, power is immediately supplied to the UV lamp, activating it. The gas thrust must also be greater than the magnet's suction force to capture the UV lamp. Calculations are required for the gas thrust between each sterilization point 501. The UV lamp must not be pushed beyond the next sterilization point 501. Furthermore, when pushing downward, the additional effect of gravity must be subtracted, while when pushing upward, the additional effect of gravity must be added.

[0066] Furthermore, the pneumatic structure includes a switch control member, which is provided at each air outlet of the ventilation duct and is used to open or close the corresponding air outlet. When the UV lamp is located at a certain air outlet and needs to be moved to the next sterilization point 501, the air outlet is opened, and the UV lamp is blown to the next sterilization point 501 by gas thrust.

[0067] Furthermore, in this embodiment, the sterilization mechanism also includes a hot air sterilization mechanism, which includes a PTC (Positive Temperature Coefficient) heater and a fan. The PTC heater and fan are both disposed within the housing 1 and are used to sterilize the items in the cavity within the housing 1 and the placement slot 201 with hot air. Preferably, the fan is disposed toward the PTC heater to achieve more even heat distribution.

[0068] like Figure 6 As shown, this embodiment also provides a sterilization method, comprising:

[0069] Step S01: Place the cutting board to be sterilized into the placement slot 201;

[0070] Depending on the size of the cutting board to be sterilized, choose whether to unfold the movable shell 3. If the cutting board is small and rectangular, it can be placed directly in the placement groove 201 for sterilization. If the cutting board is large or has a round or other special-shaped structure, the movable shell 3 can be unfolded and then placed in the placement groove 201.

[0071] Step S02, start ultraviolet sterilization;

[0072] Step S03: driving the ultraviolet lamp to move to each sterilization point 501 on the patrol track 5 in sequence and stay at each sterilization point 501 for a time t until the ultraviolet lamp returns to the initial position;

[0073] The ultraviolet lamp is driven by a pneumatic structure to move on the patrol track 5, and the movement trajectory is to move to each sterilization point 501 in turn. When the ultraviolet lamp reaches a sterilization point 501, the power of the ultraviolet lamp is turned on, and it starts to emit ultraviolet rays for sterilization and disinfection. The residence time t at each sterilization point 501 can be 1 minute. When the ultraviolet lamp needs to be moved to the next sterilization point 501, the air outlet here is opened and the gas is used to push the ultraviolet lamp to move to the next sterilization point 501, and so on, until the ultraviolet lamp passes each sterilization point 501 and returns to the initial position, completing the ultraviolet sterilization process.

[0074] Step S04: End the ultraviolet sterilization.

[0075] Furthermore, in this embodiment, the chopping board to be sterilized is a circular chopping board 10. Therefore, before the step of placing the chopping board to be cleaned into the placement slot 201, the step of opening the movable shell 3 to put it in an expanded state is also included: rotating the movable shell 3 outward so that it rotates around the hinge axis until the movable shell 3 is in the expanded state, and then placing the circular chopping board for the subsequent sterilization process.

[0076] Furthermore, in this embodiment, after placing the cutting board to be cleaned in the placement groove 201, the outer cover 4 is placed over the placement groove 201. In order to enhance the sterilization effect, the outer cover 4 is placed over the placement groove 201 and the circular cutting board 10, and the outer cover 4 is connected to the movable shell 3 using a zipper 9.

[0077] Furthermore, in this embodiment, after the step of placing the cutting board to be cleaned into the placement slot 201, hot air sterilization is also started. The dual sterilization mode of hot air sterilization and ultraviolet sterilization is used to enhance the sterilization effect.

[0078] In other embodiments, the limiting groove may also be formed on the outer wall of the side plate portion 301 , and the limiting protrusion may be provided on the inner wall of the placement groove 201 .

[0079] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
