Description

[Technical field]

[0001] The invention relates to the technical field of tableware disinfection, and in particular to a self-isolating and easy-to-use tableware disinfection device and self-isolating tableware matched therewith. [Background technology]

[0002] At present, conventional tableware disinfection cabinets usually use the principles of ozone, ultraviolet rays and electric heat disinfection to sterilize tableware. Figure 1 As shown, the structure of each bowl (plate), dining plate, spoon and chopsticks in the tableware in the prior art is exactly the same, which leads to people's habit of stacking multiple identical tableware for disinfection, which will form a mechanical seal that is extremely unfavorable for ultraviolet and ozone disinfection. According to market supervision spot checks and scientific research structures, the disinfection pass rate of reusable tableware for domestic dine-in restaurants in recent years is 50-90%. Only after a strict and complex operating procedure of chemical disinfection, cleaning and then physical disinfection can the disinfection effect reach 100%.

[0003] However, if the quality of disinfection is to be guaranteed, an effective interval must be maintained between adjacent tableware. At this time, a more careful and conscientious operator will take the trouble to arrange the tableware partitions made of steel wire according to the intervals between adjacent steel wires. However, this will cause a lot of waste in the space design and function of the disinfection cabinet, and it is difficult to ensure that every two bowls (plates), dining plates, and spoons maintain the irradiation or diffusion interval required for ultraviolet and ozone disinfection efficiency. Moreover, in many dine-in restaurants, disinfection operators are responsible for purchasing, cooking, serving, serving, cleaning, cleaning and disinfecting all-weather work. Most of them lack the concept of aseptic operation and training in tableware disinfection. When performing the disinfection operation process, they are already exhausted and will inevitably do things perfunctorily. If ultraviolet disinfection is used, ordinary opaque tableware can only be effectively disinfected on the light-receiving surface directly exposed to the ultraviolet light source, while the backlight surface or the contact surface of two tableware is disinfected by reflected light or diffused light. The disinfection effect is very low or even ineffective, unless the tableware is made of glass and other materials with good light transmittance, ultraviolet rays can penetrate the tableware and disinfect it, but the intensity of ultraviolet rays penetrating each layer of glass will be attenuated. If ozone disinfection is used, although ozone has strong oxidizing properties to kill pathogens, it cannot diffuse to the inner and outer surfaces and corners of each bowl (plate), serving plate, and spoon that are bonded together and mechanically sealed, which seriously affects the disinfection effect, and ultraviolet rays or ozone cannot kill pathogens that have been immersed in the sea surface structure of bamboo and wooden tableware. When using electric heating disinfection, the tableware should preferably be a good conductor of heat and the placement of the tableware should maximize the use of three heat transfer methods: heat conduction, heat radiation, and heat convection. However, there is no guarantee that effective spacing can be formed between the two bowls (plates), serving plates, and spoons of existing reusable disinfected tableware. Often, poor heat conductors, i.e., air, are sealed between adjacent tableware, which affects the electric heat source's ability to heat the tableware to an effective disinfection and sterilization temperature and maintain it for a sufficient period of time.

[0004] In addition, most of the existing electric disinfection cabinets still have unreasonable designs. Chopsticks, spoons and other tableware are stacked and laid flat, and the air between the tableware or in the cabinet does not form good convection. In some disinfection cabinets, the temperature at different heights forms an uneven phenomenon of hot top and cold bottom, making it difficult for the heat to evenly heat and disinfect the outer surface and corners of each bowl (plate), dining plate, and spoon. It is very easy for the tableware to become a disease medium due to incomplete disinfection, causing cross infection and leading to the spread of digestive tract diseases.

[0005] In view of this, it is necessary to provide a self-isolating and easy-to-use tableware disinfection device and self-isolating tableware matched therewith to overcome the above-mentioned defects. [Summary of the invention]

[0040] In order to make the purpose, technical solution and beneficial technical effect of the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described in this specification are only for explaining the present invention, not for limiting the present invention.

[0041] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0042] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0043] In an embodiment of the present invention, the present invention provides a self-isolated easy-to-use tableware disinfection device 100, which is used to disinfect multiple tableware with a separation point 201, fix the multiple stacked tableware placed by the user and automatically separate the edges to improve the disinfection efficiency and effect of the tableware, and the user is easy to operate. It should be noted that the self-isolated tableware of the present invention is provided with a separation point 201 on the basis of the traditional tableware structure, so that when multiple tableware is stacked, the middle part between each other will be separated by a spacing distance that matches the size of the separation point 201. It can be understood that even if there is a gap in the middle of multiple tableware, its edges will be stacked together due to inclination or different angles to form a mechanical seal, and the edges need to be separated at this time. Among them, tableware includes but is not limited to fast food plates, bowls, dishes, vegetable plates and other fast plate-shaped tableware, as well as spoons, rice shovels, soup spoons, drinking cups, chopsticks, knives and forks, colanders and other strip-shaped tableware, and the present invention is not limited here.

[0044] like Figure 2 As shown, the self-isolation easy-to-use tableware disinfection device 100 includes a cabinet 1. The cabinet 1 is in a rectangular parallelepiped shape and may be provided with one or more cabinet doors (not shown in the figure). In this embodiment, a first receiving cavity 101 is provided in the cabinet 1, and the first receiving cavity 101 is closed by a cabinet door to form a single-door disinfection cabinet.

[0045] A dry heat disinfection module 10 is provided in the first receiving chamber 101, and the dry heat disinfection module 10 includes a heat convection fan 11 and a heat source disinfector 12. The heat source disinfector 12 can generate heat sources such as ozone, ultraviolet rays, and hot air to disinfect the tableware in the first receiving chamber 101. The heat convection fan 11 is used to promote the flow of hot air in the first receiving chamber 101, thereby contact disinfecting all aspects of the tableware.

[0046] like Figure 2-Figure 3 As shown, the first receiving cavity 101 is provided with at least one horizontally arranged corrugated groove tray 20. Among them, the first receiving cavity 101 can be provided with a multi-layer structure arranged in upper and lower intervals according to the group of people to be served, and each layer can be provided with a corrugated groove tray 20 for accommodating larger tableware, such as fast food trays, bowls (plates), etc.

[0047] like Figure 3-Figure 4 As shown, each corrugated groove plate 20 includes a first V-shaped groove 21, a second V-shaped groove 22 and a third V-shaped groove 23 which are connected end to end and arranged in parallel.

[0048] Specifically, the first V-shaped groove 21 includes a first corrugated plate 31 and a second corrugated plate 32 connected at an obtuse angle, the second V-shaped groove 22 includes a third corrugated plate 33 and a fourth corrugated plate 34 connected at an obtuse angle, and the third V-shaped groove 23 includes a fifth corrugated plate 35 and a sixth corrugated plate 36 connected at an obtuse angle. The second corrugated plate 32 is connected to the third corrugated plate 33 at an obtuse angle, and the fourth corrugated plate 34 is connected to the fifth corrugated plate 35 at an obtuse angle. The end of the first corrugated plate 31 away from the second corrugated plate 32 is provided with a seventh corrugated plate 37 arranged horizontally, and the end of the sixth corrugated plate 36 away from the fifth corrugated plate 35 is provided with an eighth corrugated plate 38 arranged horizontally. Therefore, the seventh corrugated plate 37, the first V-shaped groove 21, the second V-shaped groove 22, the third V-shaped groove 23 and the eighth corrugated plate 38 are connected end to end in sequence and are continuously bent in the opposite direction to form a corrugated structure.

[0049] When a plurality of vertically stacked tableware is placed on the corrugated groove plate 20, the edge of the tableware is mounted on at least one of the first V-shaped groove 21, the second V-shaped groove 22 and the third V-shaped groove 23. For example, for the rectangular self-separating fast food plate 202, its edge is flush with a straight line, and at this time, the bottom ends of the plurality of vertically stacked self-separating fast food plates 202 are respectively mounted on the seventh corrugated plate 37 and the eighth corrugated plate 38. For the circular self-separating bowl 203, its edge is an arc, and at this time, the bottom of the plurality of vertically stacked self-separating bowls 203 can be mounted on the first V-shaped groove 21, the second V-shaped groove 22 or the third V-shaped groove 23. For the circular self-separating plate 204, which is smaller in volume than the self-separating bowl 203, its edge is a smaller arc, and at this time, the bottom of the plurality of vertically stacked self-separating plates 204 can be mounted on the first V-shaped groove 21 or the third V-shaped groove 23. It should be noted that, since the specific volumes of the self-separating fast food tray 202, the self-separating bowl 203 and the self-separating tray 204 are different, they are not limited to the above-mentioned fixing method.

[0050] like Figure 4 As shown, both sides of the first V-shaped groove 21, the second V-shaped groove 22 and the third V-shaped groove 23 are provided with a plurality of corrugated grooves 24 whose corrugation distance matches the separation point, that is, the first corrugated plate 31, the second corrugated plate 32, the third corrugated plate 33, the fourth corrugated plate 34, the fifth corrugated plate 35, the sixth corrugated plate 36, the seventh corrugated plate 37 and the eighth corrugated plate 38 are transversely provided with a plurality of corrugated grooves 24 connected in sequence end to end in a one-to-one correspondence. The distance between adjacent corrugated grooves 24 matches the separation point 201 on the tableware. For example, the distance between adjacent corrugated grooves 24 is defined as h, which is equal to the wall thickness of the tableware plus the total height of the separation point 201.

[0051] The cross-sectional extension direction of the corrugated groove 24 is perpendicular to the cross-sectional extension direction of the first V-shaped groove 21. For example, the "V"-shaped cross-section of the corrugated groove 24 extends from the X-axis direction of the horizontal plane, and the "V"-shaped cross-section of the first V-shaped groove 21 extends from the Y-axis direction of the horizontal plane. Wherein, a peak structure is formed between adjacent corrugated grooves 24, so that when multiple tableware is placed on the corrugated groove plate 20, since one corrugated groove 24 can only accommodate the edge of one tableware, and the peak structure can automatically separate the edges of two adjacent tableware, so that multiple tableware are separately inserted into the multiple corrugated grooves 24 in turn, thereby automatically forming a preset spacing distance, avoiding the edges of multiple tableware from being attached to form a mechanical seal.

[0052] Furthermore, the first corrugated plate 31, the second corrugated plate 32, the third corrugated plate 33, the fourth corrugated plate 34, the fifth corrugated plate 35, the sixth corrugated plate 36, the seventh corrugated plate 37 and the eighth corrugated plate 38 are provided with water holes 25 at both ends of each corresponding corrugated groove 24 to discharge water droplets flowing down in the tableware.

[0053] Further, such as Figure 5 As shown, the corrugated groove plate 20 is also provided with a plurality of anti-slip sheets 26 arranged in parallel and at intervals. The shape of the anti-slip sheet 26 is consistent with the cross-sectional shape of the connected structure of the first corrugated plate 31, the second corrugated plate 32, the third corrugated plate 33, the fourth corrugated plate 34, the fifth corrugated plate 35, the sixth corrugated plate 36, the seventh corrugated plate 37 and the eighth corrugated plate 38, and the plane where the anti-slip sheet 26 is located is parallel to the cross-sectional extension direction of the corrugated groove 24. Specifically, the anti-slip sheet 26 also forms a corrugated structure that is continuously bent in the reverse direction, and the height of the anti-slip sheet 26 relative to the corrugated groove plate 20 is higher than the height of the seventh corrugated plate 37, the eighth corrugated plate 38, the first V-shaped groove 21, the second V-shaped groove 22 and the third V-shaped groove 23 relative to the corrugated groove plate 20. When multiple dinner plates are placed on the corrugated groove plate 20, the anti-slip sheet 26 can provide support for the multiple dinner plates, thereby preventing the multiple dinner plates from tipping over like dominoes due to vibration or collision.

[0054] Furthermore, the corrugated groove tray 20 is also provided with a frame 27 matching a preset strength and a handle (not shown in the figure), so that it can be pushed into or moved out of the first receiving cavity 101, so that when the tableware is washed in the tableware cleaning place, it is placed on the corrugated groove tray 20 and then moved into the cabinet.

[0055] In this embodiment, when in use, various sterilized tableware that automatically maintains a good interval is placed, and the corresponding control switch is turned on, and the heat source sterilizer 12 starts to heat and heat the first receiving chamber 101 in the cabinet 1, and the hot convection fan 11 also runs to ensure that the hot air inside the first receiving chamber 101 can convect and keep the temperature of each sterilization area such as the upper, middle and lower areas consistent. Since various tableware can automatically maintain a preset interval through the corrugated grooves 24 of the corrugated groove plate 20 and other structures, and can make the hot air convect and heat on the surface of adjacent spaced tableware, the sterilization effect is more thorough and efficient.

[0056] In one embodiment, Figure 2 and Figure 6 As shown, a corrugated grid plate 40 is also provided in the first receiving cavity 101. The corrugated grid plate 40 includes a first chassis 41 provided with a plurality of corrugations and a first grid 42 mounted on the first chassis 41. Among them, the distance between adjacent corrugations of the first chassis 41 is adapted to the separation point 201. That is, a plurality of "V"-shaped corrugated grooves 24 arranged side by side and in parallel are provided on the first chassis 41. The specific structure of the V-shaped corrugated grooves can refer to the structure of the corrugated grooves 24 of the above-mentioned corrugated groove plate 20, so it is not repeated here. The first grid 42 is fixed on the first chassis 41, and includes a plurality of grids, which are used to vertically place strip-shaped tableware, such as chopsticks, spoons, rice shovels, etc., so as to provide support for the strip-shaped tableware to maintain a vertical angle and prevent the strip-shaped tableware from tipping over. Among them, the first chassis can also be provided with a plurality of water filter holes 43.

[0057] Specifically, Figure 6-Figure 8 As shown, the first grid 42 includes a plurality of first longitudinal partitions 421 and a plurality of first transverse partitions 422 which are all arranged in a vertical direction. The plurality of first longitudinal partitions 421 and the plurality of first transverse partitions 422 are cross-fixed to form a square grid plate, and the structure is similar to a nine-square grid structure with more grids. Among them. The plurality of first longitudinal partitions 421 are fixed on the first chassis 41, and the first transverse partitions 422 are fixed on the first longitudinal partitions 421. The top side of each first longitudinal partition 421 is provided with a plurality of first sockets 423 which are arranged vertically and correspond one-to-one with the plurality of first transverse partitions 422, and the bottom side of each first transverse partition 422 is provided with a plurality of second sockets 424 which are arranged vertically and correspond one-to-one with the plurality of first longitudinal partitions 421, and the second sockets 424 are inserted into the first sockets 423 one-to-one to form a plurality of grids. For example, each first longitudinal partition 421 is provided with n first sockets 423 corresponding to the number of first transverse partitions 422, and each first transverse partition 422 is provided with m second sockets 424 corresponding to the number of first longitudinal partitions 421. When the first sockets 423 and the second sockets 424 are aligned and inserted into each other, the first grid 42 is divided into (m+1)*(n+1) grids, and it can also ensure that no displacement occurs between the first longitudinal partition 421 and the first transverse partition 422.

[0058] In one embodiment, Fig. 9 As shown, the cabinet 1 can also be a double-door structure, and each door corresponds to a closed receiving cavity. In this embodiment, a second receiving cavity 102 separated from the first receiving cavity 101 is further provided in the cabinet 1. The first receiving cavity 101 is arranged below the cabinet 1, and the second receiving cavity 102 is arranged above the cabinet 1, and the two are arranged separately. The second receiving cavity 102 is provided with a water bath heating module 50, and the water bath heating module 50 is used to disinfect tableware by water bath heating. The water bath heating module 50 can perform water bath heating on chopsticks, spoons, rice shovels, soup spoons and other tableware that cannot use stainless steel tableware, or although stainless steel tableware is used, it is not desired to secondary process a plurality of convex separation points or concave separation points on one side.

[0059] Specific, combined Fig.10 As shown, the water bath heating module 50 includes a hot bath grid plate 51, a drain port 52 provided at the bottom of the hot bath grid plate 51, a steam exhaust port 53 provided at the top of the second receiving chamber 102, and an electric heating pipe 54 provided in the hot bath grid plate 51. The hot bath grid plate 51 includes a second chassis 511 provided with a plurality of corrugations and a second grid 512 mounted on the second chassis 511. The distance between adjacent corrugations of the second chassis 511 is adapted to the separation point 201, and its structure may be consistent with the first chassis 41 described above. The second grid 512 includes a plurality of grids, and the grids are used to vertically place strip-shaped tableware. In other embodiments, the second chassis 511 may also be provided without corrugations, and the surface may present a planar structure.

[0060] Among them, Figure 11-Figure 12 As shown, the second grid 512 includes a plurality of second longitudinal partitions 513 and a plurality of second transverse partitions 514, all of which are arranged in a vertical direction. The plurality of second longitudinal partitions 513 are fixed on the second chassis 511. The top side of each second longitudinal partition 513 is provided with a plurality of third sockets 515 arranged vertically and corresponding to the plurality of second transverse partitions 514 one by one, and the bottom side of each second transverse partition 514 is provided with a plurality of fourth sockets 516 arranged vertically and corresponding to the plurality of second longitudinal partitions 513 one by one. The fourth sockets 516 are inserted into the third sockets 515 one by one to form a plurality of grids. For example, each second longitudinal partition 513 is provided with x third sockets 515 corresponding to the number of second transverse partitions 514, and each second transverse partition 514 is provided with y fourth sockets 516 corresponding to the number of second longitudinal partitions 513. The third sockets 515 and the fourth sockets 516 are perpendicularly intersected to divide the second grid 512 into (y+1)*(x+1) grids.

[0061] Furthermore, the second longitudinal partition plate 513 and the second transverse partition plate 514 are both provided with a plurality of water holes 55 , so as to facilitate the water in the hot bath grid plate 51 to flow through each grid.

[0062] In the specific water bath disinfection process, ordinary chopsticks, spoons, rice spatulas and soup spoons without separation points 201 can be inserted into the hot water of the grid for water bath heating disinfection. Even if the gaps between the tableware are small, water can penetrate as much as possible. Even if there are some gaps that cannot be penetrated, the remaining air will expand in volume after being heated by the water bath with a larger specific heat capacity, and rise under the action of buoyancy and be replaced and supplemented by hot water, thereby overcoming the problem of uneven heating caused by the small gaps between the ordinary tableware produced by the one-time processing technology.

[0063] The present invention also provides a self-separating tableware 200, please refer to Figure 2 , Fig. 9 as well as Figure 13-Figure 20 , a plurality of separation points 201 are randomly or fixedly processed on the self-partitioning tableware 200, and the separation points 201 are solid or non-solid protrusions. Solid protrusions can be set at fixed edge positions near the four corners of the tableware, and non-solid protrusions can be set at the positions where a plurality of separation points 201 are randomly processed. Among them, the self-partitioning tableware 200 can be further processed from ordinary tableware, for example, a plurality of convex separation points or concave separation points are processed on ordinary tableware individuals according to a random program using a punching machine, and the total height of the convex separation points or concave separation points and the thickness of the tableware wall can be defined as h. Ordinary tableware includes but is not limited to stainless steel fast food plates, stainless steel bowls, stainless steel plates, stainless steel spoons, stainless steel rice shovels, stainless steel soup spoons, ordinary drinking cups, etc.

[0064] Specifically, Fig.13 As shown, a plurality of convex separation points or concave separation points are formed by secondary processing of a common stainless steel fast food tray 211 to form a self-separating fast food tray 202; Fig.14 As shown, the ordinary stainless steel bowl 212 is processed to have a plurality of convex separation points or concave separation points to form a self-separated bowl 203; Fig.15 As shown, the ordinary stainless steel plate 213 is processed to have a plurality of convex separation points or concave separation points to form a self-separating plate 204; Fig.16 As shown, the ordinary stainless steel spoon 214 is processed to have a plurality of convex separation points or concave separation points to form a self-separating spoon 205; Fig.17 As shown, the ordinary stainless steel rice shovel 215 is processed to have a plurality of convex separation points or concave separation points to form a self-separating rice shovel 206; Fig.18 As shown, the ordinary stainless steel spoon 216 is processed to have a plurality of convex separation points or concave separation points to form a self-separating spoon 207; Fig.19 As shown, the ordinary drinking cup 217 is processed twice to form a plurality of convex separation points or concave separation points to form a self-isolating drinking cup 208.

[0065] It should be noted that the stainless steel chopsticks are made of food-grade (such as 304 stainless steel) metal materials, and they are processed into a chamfered long cylindrical shape or a cylindrical and rectangular structure, and there is an original gap between them, so there is no need to re-process the concave or convex separation points. For the relatively "slender" strip tableware of the self-separating spoon 205, the self-separating rice shovel 206, the self-separating soup spoon 207, and the self-separating drinking cup 208, the relatively "slender" bar tableware is used. The characteristics of the vertical or oblique placement of the tableware with a high center of gravity and a tendency to fall all over the place can ensure that the distance between the same tableware is at least h (when they are closely and regularly placed in an array), which is relatively space-saving and conducive to the convection circulation of dry hot air between the tableware pieces to achieve uniform heating and disinfection.

[0066] All the self-separating tableware 200 mentioned above can be matched with the self-separating easy-to-use tableware disinfection device 100, which adopts the electric heating disinfection method. For the self-separating tableware 200 that uses secondary processing of concave separation points or convex separation points for all tableware except chopsticks, a single door structure with a dry heat disinfection module 10 can be used in conjunction with it. For users who cannot use stainless steel tableware for chopsticks, spoons, rice shovels, soup spoons, etc., or who use stainless steel tableware but do not want to secondary process multiple convex separation points or concave separation points on one side, a double door structure can be used in conjunction with it, the upper part of which uses a water bath heating module 50 and the lower part uses a dry heat disinfection module 10.

[0067] It should be noted that a plurality of concave separation points or convex separation points are randomly processed on a plane or inclined surface on one side of ordinary tableware, and the height including the wall thickness of the plate is h. After being processed, multiple tableware of the same kind are different due to the different positions of the randomly processed plurality of concave separation points or convex separation points. That is, the probability that two tableware of the same kind are processed with separation point 201 at the same position is extremely small, and the probability that all positions between the two tableware are processed with exactly the same plurality of concave separation points or convex separation points is close to zero. Therefore, after further processing of ordinary tableware, countless tableware that is different due to the different positions of the plurality of concave separation points or convex separation points is formed. After each two similar tableware are overlapped, they are automatically pushed apart by the plurality of concave separation points or convex separation points to form a gap of a distance of h.

[0068] In other embodiments, Fig. 20 As shown, a long strip concave-convex point 209 structure can also be processed at a fixed position on an ordinary tableware, and the total height of the long strip concave-convex point 209 and the wall thickness of the tableware is defined as h. During the processing, the rotation angle of the long strip concave-convex point 209 is randomly changed to form a gap of h when the self-separating dining plates 200 are stacked. Due to the different rotation angles of the long strip concave-convex points 209, when adjacent tableware is stacked, the long strip concave-convex points 209 at the same position will not completely overlap, thereby forming a gap of h.

[0069] In another embodiment, solid concave-convex points with a total height of h can be set at the four corners of the fixed common tableware. Since the concave-convex points are solid structures, when adjacent tableware is stacked, the concave-convex separation points at the same position will not be embedded and thus push apart to form a gap of h.

[0070] In another embodiment, a strip-shaped protrusion may be fixed at a fixed position of the ordinary tableware by welding or molding. For example, the protrusion may be a straight line or a curved line matching the tableware, so that stacked identical tableware can be separated.

[0071] In summary, the self-isolating and easy-to-use tableware disinfection device 100 and the self-isolating tableware 200 matched therewith provided by the present invention are provided with a first V-shaped groove 21, a second V-shaped groove 22 and a third V-shaped groove 23 which are connected end to end and arranged in parallel on the corrugated groove plate 20, and a corresponding corrugated groove 24 is provided. When a plurality of vertically stacked tableware are placed in the V-shaped groove of the corrugated groove plate 20, the plurality of corrugated grooves 24 will automatically separate the edges of the plurality of tableware, so that when the same kind of tableware is stacked, an equal interval can be automatically formed, which is convenient for the air to form heat convection, thereby creating good uniform heating conditions for the tableware, and thus, combined with the separation point 201 provided on the tableware itself, the plurality of tableware can be fixed, and the plurality of tableware can be automatically separated by a preset interval distance, thereby avoiding mechanical sealing of the plurality of stacked tableware during disinfection, thereby improving the disinfection effect and efficiency of the tableware disinfection, and the user is easy to operate.

[0072] It should be noted that in addition to being able to efficiently disinfect the above tableware, the present invention can also disinfect tableware such as knives, forks, and colanders, as long as the disinfection temperature and time are controlled within the rated range. For example, the disinfection cabinet can be heated to a temperature of about 130 degrees using an electric heating tube, so that the proteins of dangerous pathogens such as Salmonella, Shigella, Listeria, hepatitis B, COVID-19 virus, living parasites or eggs, and cholera, plague, monkeypox, and polio attached to the surfaces of various tableware placed therein are denatured and their genetic material is destroyed and inactivated, thereby achieving the purpose of completely killing pathogens, disinfecting and even sterilizing tableware, and preventing the spread of digestive tract infectious diseases through public dine-in dining tableware.

[0073] The present invention is not limited to what is described in the specification and implementation modes, and therefore additional advantages and modifications can be easily realized by those skilled in the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
