Description

Technical Field

[0001] This application relates to the field of sterilization equipment technology, and in particular to a sterilization machine. Background Technology

[0002] As living standards improve, people are paying more and more attention to the hygiene of various utensils in the kitchen that come into contact with food. Disinfection cabinets, due to their large size and footprint, cannot be used extensively in the limited kitchen space. In contrast, sterilization machines, because of their small size, can be placed anywhere on the kitchen countertop and can also store cutting boards, knives, chopsticks, etc., are widely used.

[0003] After use, cutting boards usually retain a lot of water stains. When the cutting board is placed in a sterilizer, the water stains cannot be drained in time, which can easily breed bacteria and is not conducive to people's health requirements when using it. Utility Model Content

[0004] Therefore, it is necessary to provide a sterilization machine that can better promote the removal of residual water stains on cutting boards to address the above problems.

[0005] This application provides a sterilizer, including a housing, a shelf, and a base. The housing has a first opening and a second opening disposed opposite to each other, forming an accommodating space between the first opening and the second opening. The shelf is connected to the first opening and has a cutting board placement area formed on the shelf. The base is connected to the second opening, and the inner wall of the base facing the accommodating space has a first area corresponding to the cutting board placement area. The first area has a plurality of support portions protruding toward the shelf, and the support portions are spaced apart from each other. Each support portion is constructed as a hemispherical shape, and the cross-sectional diameter of each support portion gradually decreases from the end connected to the base to the end away from the base.

[0006] With the above structure, each support part can support the bottom of the cutting board. And because each support part is protruding, residual water stains on the cutting board can be drained better, making the bottom of the cutting board drier and reducing the probability of bacteria growing due to water stains.

[0007] Furthermore, by reducing the contact area between the cutting board and the support, a larger area of ​​the bottom of the cutting board can come into contact with the air, thus better keeping it dry.

[0008] In some embodiments, the first area has a drainage hole that extends through the base.

[0009] Therefore, by setting up a drain hole, water can be smoothly discharged from inside the sterilizer, reducing the probability of water remaining inside the sterilizer and breeding bacteria.

[0010] In some embodiments, the drain hole is located at the geometric center of the first region.

[0011] Therefore, the above structure allows water to be discharged from the drain hole more quickly, reducing the probability of bacteria growing inside the sterilizer.

[0012] In some embodiments, the water-receiving platform with the support is inclined downwards toward the drain hole.

[0013] In this way, the inclined surface can guide the water flow, allowing the water to be discharged from the drain hole more quickly and more thoroughly.

[0014] In some embodiments, the rack further includes a knife placement area and a chopsticks placement area, and the inner wall of the base has a second area corresponding to the knife placement area and the chopsticks placement area; wherein, in the direction from the first opening to the second opening, the height of the second area is higher than the height of the first area.

[0015] Thus, the above structure can better remove residual water stains from inside the sterilizer, reducing the probability of bacteria growing inside the sterilizer.

[0016] In some embodiments, the base has an inner cavity, and the sterilizer further includes a drying component disposed in the inner cavity for blowing hot air into the receiving space.

[0017] The above structure allows kitchen utensils such as cutting boards, knives, chopsticks, and spoons in the storage space to be dried by hot air, reducing the probability of bacteria growing on kitchen utensils due to residual moisture.

[0018] In some embodiments, the second region is formed with an air outlet protruding toward the placement rack, and an air outlet grille is provided on the side wall of the air outlet.

[0019] The above structure allows for more precise blowing of hot air towards each kitchen appliance within the storage space, improving drying efficiency.

[0020] In some embodiments, the drying assembly includes a heating element and an air supply element, wherein the air outlet of the air supply element is disposed facing the air outlet grille, and the heating element is disposed between the air outlet of the air supply element and the air outlet grille.

[0021] With the above structure, hot air can be smoothly blown into the storage space through the air outlet grille, so as to dry the kitchen utensils inside the storage space.

[0022] In some embodiments, the base has a bottom wall disposed opposite to the inner wall, and a drain outlet is provided through the bottom wall, the drain outlet being located below the air outlet.

[0023] Therefore, by setting up a drain outlet, the water inside the sterilizer can be drained more thoroughly, further improving the overall safety of the sterilizer.

[0024] In some embodiments, a water-blocking rib protrudes from one side of the bottom wall facing the inner cavity, and the water-blocking rib is located between the drain outlet and the heating element.

[0025] Therefore, the water-blocking ribs can effectively prevent water entering from the air outlet grille from further entering the inner cavity, thereby effectively avoiding problems such as short circuits in the electrical components inside the cavity caused by water.

[0026] In some embodiments, the sterilizer further includes an ultraviolet lamp disposed in the inner cavity, and the second area has a light-transmitting hole for transmitting light emitted by the ultraviolet lamp.

[0027] By setting up light-transmitting holes, the light emitted by the ultraviolet lamps can better enter the containment space, thereby sterilizing and disinfecting kitchen utensils such as cutting boards, knives, chopsticks, and spoons within the containment space.

[0028] When the cutting board is placed in the above-mentioned sterilizer, each support part can support the bottom of the cutting board. Furthermore, due to the protruding design of each support part, residual water stains on the cutting board can be drained more effectively, making the bottom of the cutting board drier and reducing the probability of bacteria growth due to water stains.

[0044] Please refer to the following: Figure 1 , Figure 2 , Figure 3 as well as Figure 4 One embodiment of this application provides a sterilizer 100, including a housing 10, a shelf 20, and a base 30. The housing 10 has a first opening 11 and a second opening 12 disposed opposite to each other, forming a receiving space 13 between the first opening 11 and the second opening 12. The shelf 20 is connected to the first opening 11, and a cutting board placement area 21 is formed on the shelf 20. The base 30 is connected to the second opening 12, and a first area 31 corresponding to the cutting board placement area 21 is formed on the inner wall of the base 30 facing the receiving space 13. The first area 31 has a plurality of support portions 32 protruding toward the shelf 20, and the support portions 32 are spaced apart from each other.

[0045] Specifically, the interior of the housing 10 is hollow, and a first opening 11 and a second opening 12 are formed at both ends of the housing 10, respectively, with an accommodating space 13 formed between the first opening 11 and the second opening 12. That is to say, the opposite ends of the housing 10 are open.

[0046] The shelf 20 is connected to the first opening 11 of the housing 10 and is detachably connected to the housing 10. A cutting board placement area 21 is formed on the shelf 20, through which the cutting board can be placed into the receiving space 13 for storage. Specifically, inserting the cutting board into the cutting board placement area 21 allows it to extend into the receiving space 13, thus achieving the placement and storage of the cutting board.

[0047] The base 30 is connected to the second opening 12 of the housing 10, and the base 30 can also be detachably connected to the housing 10. When the cutting board is placed from the cutting board placement area 21 into the receiving space 13, the bottom of the cutting board is supported on the base 30.

[0048] The side of the base 30 facing the interior of the receiving space 13 is constructed as an inner wall, and the inner wall has a first area 31 corresponding to the cutting board placement area 21. That is, the first area 31 is aligned with the cutting board placement area 21 so that after the cutting board is placed from the cutting board placement area 21 into the receiving space 13, the bottom of the cutting board can be supported in the first area 31.

[0049] Furthermore, multiple support portions 32 are provided in the first zone 31, with each support portion 32 protruding towards the shelf 20 and spaced apart from the others. Thus, when the cutting board is supported in the first zone 31, the bottom of the cutting board is actually supported on each support portion 32, reducing the contact area between the bottom of the cutting board and each support portion 32. This allows water on the cutting board to flow downwards under gravity, thus keeping the cutting board dry and reducing the probability of bacterial growth.

[0050] With the above structure, each support part 32 can provide support for the bottom of the cutting board. Since each support part 32 is protruding, residual water stains on the cutting board can be drained better, making the bottom of the cutting board drier and reducing the probability of bacteria growing due to water stains.

[0051] In some embodiments, each support portion 32 is configured as a hemispherical shape, and the cross-sectional diameter of each support portion 32 gradually decreases from the end connected to the base 30 to the end away from the base 30.

[0052] Specifically, the hemispherical support 32 can support the cutting board while further reducing the contact area with the cutting board, achieving point contact with the cutting board, and allowing a larger area of ​​the bottom of the cutting board to come into contact with the air, thereby better keeping it dry.

[0053] Therefore, by using the above structure, the contact area between the cutting board and the support 32 is reduced, allowing a larger area of ​​the bottom of the cutting board to come into contact with the air, thereby better keeping it dry.

[0054] like Figure 5 and Figure 6 As shown, in some embodiments, the first region 31 is provided with a drain hole 33, which is disposed through the base 30.

[0055] Specifically, a drain hole 33 is located in the first zone 31 and extends through the base 30 along its height. Thus, when the cutting board is placed in the sterilizer 100, the water at the bottom of the cutting board can not only be better separated from the board, but also quickly drained from the sterilizer 100 through the drain hole 33, keeping the inside of the sterilizer 100 dry and effectively reducing the probability of bacterial growth inside the sterilizer 100.

[0056] Therefore, by setting the drain hole 33, water can be smoothly discharged from the inside of the sterilizer 100, reducing the probability of water remaining inside the sterilizer 100 and causing bacteria to grow.

[0057] In some embodiments, the drain hole 33 is located at the geometric center of the first region 31.

[0058] Specifically, by placing the drain hole 33 in the middle area of ​​the first zone 31, the water flow inside the sterilizer 100 can be better collected, and the water flow can be discharged more quickly.

[0059] Furthermore, the drain hole 33 is located at the geometric center of the first zone 31, which is more conducive to the rapid discharge of water.

[0060] Therefore, the above structure allows water to be discharged from the drain hole 33 more quickly, reducing the probability of bacteria growing inside the sterilizer 100.

[0061] In some embodiments, the water receiving platform with the support 32 is inclined at a downward slope toward the drain hole 33.

[0062] Specifically, the inner wall of the base 30 is configured as an inclined surface with a downward slope toward the drain hole 33. In this way, the inclined surface can guide the water flow, allowing the water to be discharged from the drain hole 33 more quickly and more thoroughly.

[0063] like Figure 1 , Figure 4 as well as Figure 5As shown, in some embodiments, the rack 20 also has a knife placement area 22 and a chopsticks placement area 23, and the inner wall of the base 30 has a second area 34 corresponding to the knife placement area 22 and the chopsticks placement area 23. The height of the second area 34 is higher than the height of the first area 31 in the direction from the first opening 11 to the second opening 12.

[0064] Specifically, the rack 20 can be used to hold not only cutting boards, but also knives, chopsticks, spoons, or other kitchen utensils. The knife storage area 22 may include spaced-apart wavy ribs, with a space between each adjacent rib for inserting a knife. The chopstick storage area 23 can be used not only for chopsticks, but also for spoons, forks, and other utensils. The chopstick storage area 23 is designed with a basket-like structure to facilitate drainage and sterilization of chopsticks, spoons, etc.

[0065] Furthermore, the inner wall of the base 30, aligned with the knife placement area 22 and the chopsticks placement area 23, forms a second zone 34. The height of the second zone 34 is higher than that of the first zone 31. Thus, water remaining on the knife and chopsticks / spoon flows into the second zone 34 and then into the first zone 31, eventually draining out through the drain hole 33 of the first zone 31.

[0066] Thus, the above structure can better remove residual water stains inside the sterilizer 100, reducing the probability of bacteria growing inside the sterilizer 100.

[0067] like Figure 2 As shown, in some embodiments, the base 30 has an inner cavity 35, and the sterilizer 100 also includes a drying component 36 disposed in the inner cavity 35, the drying component 36 being used to blow hot air into the receiving space 13.

[0068] Specifically, the drying component 36 is disposed in the inner cavity 35 of the base 30 and can blow hot air into the accommodating space 13, so that the cutting board, knives, chopsticks, spoons and other kitchen utensils in the accommodating space 13 can be dried under the action of hot air, reducing the probability of bacteria growing on the kitchen utensils due to residual moisture.

[0069] In some embodiments, the second region 34 is formed with an air outlet 37 protruding toward the placement rack 20, and an air outlet grille 371 is provided on the side wall of the air outlet 37.

[0070] Specifically, the second zone 34 can be protruding into the accommodating space 13 so that an air outlet 37 is formed on the inner wall. The air outlet 37 has a top wall and side walls surrounding the top wall. The top wall is parallel to the inner wall of the base 30, and the side walls are perpendicular to the side walls of the base 30.

[0071] An air outlet grille 371 is provided on the side wall and is oriented toward the receiving space 13. In this way, the drying assembly 36 is positioned at the corresponding position of the air outlet 37, and the drying assembly 36 can blow hot air toward the air outlet grille 371. The hot air is blown through the air outlet grille 371 toward the various kitchen utensils in the receiving space 13, thereby achieving drying.

[0072] The above structure allows for more accurate blowing of hot air toward each kitchen appliance within the storage space 13, thereby improving drying efficiency.

[0073] In some embodiments, the drying assembly 36 includes a heating element 361 and an air supply element 362, with the air outlet of the air supply element 362 facing the air outlet grille 371, and the heating element 361 disposed between the air outlet of the air supply element 362 and the air outlet grille 371.

[0074] Specifically, the heating element 361 may be, but is not limited to, a PTC heating element. Both the PTC heating element and the air supply element 362 are disposed in the inner cavity 35, and the air outlet of the air supply element 362 is oriented toward the air outlet grille 371. The PTC heating element is located between the air outlet of the air supply element 362 and the air outlet grille 371.

[0075] Thus, the air supply component 362 blows airflow toward the air outlet grille 371. The airflow is heated after passing through the PTC heating element, forming hot air, which is finally blown from the air outlet grille 371 to the accommodating space 13.

[0076] With the above structure, hot air can be smoothly blown into the storage space 13 through the air outlet grille 371 to dry the kitchen utensils inside the storage space 13.

[0077] In addition, a fixing cover can be installed in the inner cavity 35, and the PTC heating element can be fixed on the fixing cover. Then, the fixing cover can be fixed in the inner cavity 35 by bolts or other connection methods. In this way, the PTC heating element can be stably set in the inner cavity 35, making the formation of hot air more stable.

[0078] Please refer to the following: Figure 2 and Figure 7 In some embodiments, the base 30 has a bottom wall opposite to the inner wall, and a drain outlet 38 is provided through the bottom wall, which is located below the air outlet 37.

[0079] Specifically, during the process of blowing hot air into the accommodating space 13 through the air outlet grille 371, water droplets may form at the location of the air outlet grille 371. Therefore, the water near the air outlet grille 371 can be discharged through the drain outlet 38, preventing the inner cavity 35 from being filled with water due to the inability to drain, which could cause malfunctions such as short circuits in other electrical components in the inner cavity 35.

[0080] Therefore, by setting the drain outlet 38, the water inside the sterilizer 100 can be drained more thoroughly, further improving the overall safety of the sterilizer 100.

[0081] In some embodiments, a water-blocking rib 39 is formed by protruding on the side surface of the bottom wall facing the inner cavity 35, and the water-blocking rib 39 is located between the drain outlet 38 and the heating element 361.

[0082] Therefore, the water-blocking rib 39 can effectively prevent water entering from the air outlet grille 371 from further entering the inner cavity 35, thereby effectively avoiding problems such as short circuits in the electrical components of the inner cavity 35 caused by water.

[0083] like Figure 8 As shown, in some embodiments, the sterilizer 100 also includes an ultraviolet lamp (not shown) disposed in the inner cavity 35, and a light-transmitting hole 341 is provided in the second zone 34 for transmitting light emitted by the ultraviolet lamp.

[0084] By setting up the light-transmitting hole 341, the light emitted by the ultraviolet lamp can better enter the containing space 13, thereby sterilizing and disinfecting kitchen utensils such as cutting boards, knives, chopsticks, and spoons in the containing space 13.

[0085] In addition, indicator lights 14 and touch buttons 15 can be provided on the housing 10, and a control board can be provided in the inner cavity 35. The indicator lights 14 and touch buttons 15 can be controlled through the control board, so as to better control the usage status of the sterilizer 100.

[0086] According to one or more embodiments, when this application is used in its initial state, the placement rack 20, the housing 10 and the base 30 form a whole, and the cutting board can be placed in the cutting board placement area 21, the knife can be placed in the knife placement area 22, and the chopsticks, spoons and other utensils can be placed in the chopsticks placement area 23.

[0087] Then, by using the indicator light 14 and touch button 15 on the housing 10, the working status of the sterilizer 100 can be adjusted, which can respectively achieve drying or sterilization of kitchen utensils such as cutting boards, knives, chopsticks and spoons.

[0088] Furthermore, when the cutting board is placed inside the sterilizer 100, the bottom of the cutting board is supported on each support part 32, allowing the bottom of the cutting board to have a larger area in contact with the air, so that water stains on the cutting board can be better drained away and the cutting board can be drier.

[0089] Water drained from the cutting board, as well as water from the knives, chopsticks, and spoons, can be drained through the drain hole 33, keeping the interior of the containment space 13 dry.

[0090] In addition, during drying, water near the air outlet grille 371 can be discharged through the drain hole 38, and the water-blocking ribs 39 effectively prevent water entering from the air outlet grille 371 from further entering the inner cavity 35, thus better keeping the inner cavity 35 dry.

[0091] 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.

[0092] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
