Description

Cutting board sterilizer

[0001] The present invention relates to a cutting board sterilizing device, and more specifically, to a cutting board sterilizing device that can always create a hygienic kitchen environment by sterilizing a cutting board using visible light wavelengths that are harmless to the human body but have a sterilizing function.

[0002] A cutting board is a tool used to cut various ingredients when cooking.

[0003] To maintain a clean and sanitary condition, cutting boards should be washed to remove any food residue remaining on the board, dried, and then regularly disinfected.

[0004] If food residue left on a cutting board is not sterilized, bacteria can multiply and cause various diseases.

[0005] However, there are very few households that sterilize cutting boards before use.

[0006] Cutting boards have microscopic wounds from knives and do not dry out easily, creating an environment suitable for bacteria to grow.

[0007] To sterilize a cutting board, sterilization is carried out by applying heat, boiling, or placing it in a UV sterilizer.

[0008] The most commonly used household or commercial dish sterilizers today are primarily designed to sterilize dishes, and are not suitable for sterilizing cutting boards. Furthermore, there is the inconvenience of having to fit the cutting board to the size of the sterilizer.

[0009] In addition, even in the case of dedicated sterilization devices for disinfecting cutting boards, they were bulky, inconvenient to store, and expensive, making them difficult to use at home.

[0059] However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms.

[0060] The embodiments herein are provided to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention.

[0061] And the present invention is defined only by the scope of the claims.

[0062] Accordingly, in some embodiments, well-known components, well-known operations, and well-known techniques are not specifically described to avoid obscuring the present invention.

[0063] Additionally, throughout the specification, the same reference numerals refer to the same components, and the terminology used (referred to) in this specification is for the purpose of describing embodiments and is not intended to limit the present invention.

[0064] In this specification, the singular includes the plural unless specifically stated otherwise in the phrase, and the reference to an element or action as “including (or comprising)” does not exclude the presence or addition of one or more other elements or actions.

[0065] Unless otherwise defined, all terms (including technical and scientific terms) used herein may be used in a meaning that can be commonly understood by a person of ordinary skill in the art to which the present invention belongs.

[0066] Also, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless they are defined otherwise.

[0067] Hereinafter, a preferred embodiment of the present invention will be described with reference to the attached drawings.

[0068] First, FIG. 1 is a perspective conceptual diagram illustrating sterilization of a cutting board (300) using a cutting board sterilization device according to one embodiment of the present invention.

[0069] And, FIGS. 2 and 3 are perspective conceptual diagrams showing the appearance of a cutting board sterilizing device according to another embodiment of the present invention.

[0070] In addition, FIG. 4 is a plan view conceptually illustrating the appearance of a cutting board sterilizing device according to another embodiment of the present invention.

[0071] In addition, FIG. 5 is an exploded perspective view illustrating the overall joint structure of a cutting board sterilization device according to another embodiment of the present invention.

[0072] As shown in FIGS. 1 to 4, the present invention may be applied to an embodiment of a structure including a main body (100) having an upper surface on which a used cutting board (300) is placed, and a sterilizing unit (200) including a plurality of sterilizing visible light LEDs (201) formed on the main body (100) described above and irradiating sterilizing visible light of a wavelength of 405 nm toward an opposing surface of the used cutting board (300) facing the upper surface of the main body (100).

[0073] The present invention can be applied to the above-described embodiments, and of course, the following various embodiments can also be applied.

[0074] First, referring to FIG. 5 together with FIG. 1 to FIG. 4, the main body (100) may be applied to an embodiment that includes an upper case (110) that forms the upper surface of the main body (100) and on which a used cutting board (300, see FIG. 1 below) is placed, and a lower case (120) that forms the lower surface of the main body (100) and is positioned at the lower portion of the upper case (110) and coupled to the upper case (110).

[0075] Here, the upper and lower cases (110, 120) can be typically made of stainless steel such as SUS301, but may also be made of synthetic resin for convenience in maintenance, storage, and transportation, such as cost or increased load of the product itself.

[0076] For example, the upper and lower cases (110, 120) may be made of a material with excellent durability and impact resistance, such as polycarbonate or ABS resin, and when the upper and lower cases (110, 120) are manufactured using the aforementioned synthetic resin material, a special waterproof coating may be additionally applied to the surface.

[0077] In addition, it goes without saying that the synthetic resin material described above can be used to manufacture not only the upper and lower cases (110, 120), but also the housing (130) described later, which is formed integrally with the upper case (110).

[0078] At this time, a plurality of sterilizing visible light LED bars (210) in which a plurality of sterilizing visible light LEDs (201) are arranged in a row are arranged between the upper case (110) and the lower case (120) to irradiate sterilizing visible light through the upper surface of the upper case (110).

[0079] UV LEDs are commonly used for sterilization, but UV wavelengths have a fatal drawback in that they can cause harmful effects such as skin aging and vision damage when exposed to the human body.

[0080] Therefore, these UV LEDs are used for sterilization in confined spaces, such as inside ultraviolet sterilizers, air conditioners, or fish tank filtration tanks.

[0081] To compensate for these shortcomings, among the sterilization-related studies using visible light with a wavelength of 400 to 700 nm, which does not have a harmful effect on the human body when exposed to it, it is known that the sterilization effect of LEDs that irradiate visible light with a wavelength of 405 nm is excellent.

[0082] Kumar et al. (2015) compared the sterilization effects of 405 nm LED and 520 nm LED and reported that 405 nm LED showed much better sterilization performance, and Maclean et al. (2009) reported that 405 nm LED had a sterilization effect on both gram-positive and gram-negative bacteria that frequently occur in hospitals and daily life.

[0083] Murdoch et al. (2013) reported that the bactericidal effect was clearly demonstrated not only against bacteria but also against fungi such as Aspergillus niger.

[0084] Meanwhile, at least one fan (400) is formed on one side of the upper surface of the main body (100) to spray air toward the used cutting board (300) placed on the upper surface of the main body (100), thereby drying the cutting board (300).

[0085] More specifically, the fan (400) is formed on the upper surface of the upper case (110) and is placed on one end of the upper case (110) to inject air toward the used cutting board (300) mounted on the upper case (110).

[0086] For this purpose, a controller (not shown) is electrically connected to the fan (400) and is built into one end of the upper case (110) to control the operation of the fan (400) or to control the on / off of the cutting board sterilization device.

[0087] Meanwhile, the cutting board sterilization device according to the present invention may be equipped with a sterilization structure inside the main body (100) using UV LED as follows so that it can sterilize not only cutting boards (300) but also frequently used kitchen utensils such as knives or scissors.

[0088] That is, a plurality of entry slots (119) are formed on the side of the upper case (110) and are arranged on the other end of the upper case (110), so that kitchenware including used knives or scissors can be stored or taken out.

[0089] In addition, a plurality of sterilizing UV LED bars (220) in which a plurality of UV LEDs (202) that irradiate UV wavelengths are arranged in a row can be placed between the upper case (110) and the lower case (120).

[0090] The controller may be electrically connected to a plurality of sterilizing UV LED bars (220) and a plurality of sterilizing visible light LED bars (210) to control the operation of the plurality of sterilizing UV LED bars (220) and the plurality of sterilizing visible light LED bars (210) or to control the on / off of the cutting board sterilizer.

[0091] Here, the plurality of sterilizing UV LED bars (220) and the plurality of sterilizing visible light LED bars (210) may repeat a pattern in which one sterilizing UV LED bar (220) among the plurality of sterilizing UV LED bars (220) and one sterilizing visible light LED bar (210) among the plurality of sterilizing visible light LED bars (210) are arranged in parallel and alternately.

[0092] Meanwhile, on one side of the upper surface of the upper case (110), a hollow housing (130) may be formed to protrude from the upper surface of the upper case (110) along one edge of the upper case (110).

[0093] Here, an on / off button (140) is formed on the upper surface of the housing (130) and is electrically connected to the controller to turn the power of the cutting board sterilizing device according to the present invention on / off.

[0094] At this time, a plurality of status display LEDs (150) are formed on the upper surface of the housing (130) and electrically connected to the controller to help visually determine whether the sterilization, drying, and operation of the cutting board sterilizer according to the present invention have been completed.

[0095] In addition, a power supply unit (160) is formed on the side of the upper case (110) and is placed on one end of the upper case (110), and is electrically connected to the controller to supply power to the cutting board sterilizer from the outside.

[0096] Accordingly, it can be seen that a fan (400), a controller, and a power supply unit (160) can be built into the interior of the housing (130).

[0097] Here, the status display LED (150) may include a sterilizing light (151) that lights up to indicate that a currently used cutting board (300), knife, or scissors is being sterilized by operating a plurality of sterilizing UV LED bars (220) or a plurality of sterilizing visible light LED bars (210).

[0098] At this time, the status display LED (150) may include a drying light (152) that lights up to indicate that at least one fan (400) is operating and the currently used cutting board (300) is drying.

[0099] Additionally, the status indicator LED (150) may include a completion light (153) that lights up to indicate that operation of a plurality of sterilizing UV LED bars (220) or a plurality of sterilizing visible light LED bars (210) is complete, or that operation of at least one fan (400) is complete.

[0100] In addition, the status display LED (150) may include a power light (154) that lights up when the on / off button (140) is pressed in conjunction with the on / off button (140) to indicate that the cutting board sterilizer is on.

[0101] At this time, the completion light (153) will light up when the sterilization light (151) or drying light (152) is turned off.

[0102] Meanwhile, the cutting board sterilization device according to the present invention may add the following configuration to form a passage for air taken out by the fan (400) so that drying by the fan (400) described above can be smoothly performed.

[0103] First, air outlets (132) are formed as many times as the number of fans (400) on the side of the housing (130) so that air generated from the fans (400) can be supplied through the upper surface of the upper case (110).

[0104] And, the main air channel (111) is formed parallel to the upper surface of the upper case (110) from one end of the upper case (110) to the edge of the other end of the upper case (110) by a number of sterilizing visible light LED bars (210).

[0105] Additionally, a communication air channel (112) may be formed recessed in the upper surface of the upper case (110) to communicate with one end of each of the plurality of main air channels (111).

[0106] Accordingly, the air extracted from the fan (400) can dry the cutting board (300) placed on the upper surface of the upper case (110) while moving in the direction of the transparent thick arrow in FIG. 4.

[0107] Meanwhile, the present invention may further include an installation slot (113) and a first optical cover (114) to protect a plurality of sterilizing visible light LED bars (210) arranged between upper and lower cases (110, 120) from moisture or foreign substances while allowing irradiation of sterilizing visible light.

[0108] The installation slot (113) is formed in a long hole shape that is formed to correspond to a plurality of sterilizing visible light LED bars (210) on the upper surface of the upper case (110) and is respectively placed in the main air channel (111).

[0109] The first optical cover (114) is installed in the installation slot (113) and is made of a transparent or translucent material that allows irradiation of sterilizing visible light from each of the plurality of sterilizing visible light LED bars (210).

[0110] Meanwhile, the cutting board sterilization device according to the present invention may further include an installation bracket (131) installed inside the housing (130) and positioned at the edge of the air outlet (132) to fix the fan (400).

[0111] In addition, the cutting board sterilization device according to the present invention may further include a PCB (170) installed inside the housing (130) and electrically connected to a fan (400), a plurality of sterilizing UV LED bars (220), a plurality of sterilizing visible light LED bars (210), a controller, and a power supply unit (160).

[0112] In addition, the cutting board sterilization device according to the present invention may further include a DC jack (160) that is installed on a PCB (170) and connected to an external power source, as a power supply unit (160).

[0113] In addition, the cutting board sterilization device according to the present invention may further include a second optical cover (115) made of a transparent or translucent material, which is installed on the ceiling surface of the upper case (110) and is placed between each of the sterilizing UV LED bars (220) and the lower case (120), and allows UV wavelengths to be irradiated from the sterilizing UV LED bars (220).

[0114] Meanwhile, the cutting board sterilization device according to the present invention may further include a plurality of anti-slip pads (121) arranged on the lower surface of the lower case (120) to prevent slipping.

[0115] Hereinafter, the operation and effect of a cutting board sterilization device according to a preferred embodiment of the present invention will be examined as follows.
