Description

[Detailed explanation of the idea]

(Field of Industrial Application) The present invention relates to a sterilizing ultraviolet irradiation box for cooking utensils such as cooking tables, finishing plates, knives, chopsticks, and tableware. (Prior art) Conventionally, cooking utensils such as knives, chopsticks, etc., such as kitchen utensils, which often cause food poisoning, are usually disinfected and sterilized by washing them with water or exposing them to sunlight. It is time-consuming to clean the food with water, and irradiation with sunlight requires a long time, making it difficult to completely sterilize food, and food poisoning continues to occur.
Therefore, in kitchens where knives are often used, the current practice is to immerse the knives in water boxes containing quicklime as a measure to prevent food poisoning and also to prevent rust. (Problem that the invention aims to solve) However, as mentioned above, washing with water has no cleaning effect unless it is rinsed with clean water several times.
In addition, sunlight irradiation takes several hours to completely sterilize, and both methods have the problem of being troublesome and time-consuming.
Furthermore, the method of immersing knives in a water box has the problem that the water tends to spoil if a large number of knives are soaked for a long time. (Means for solving the problem) The present invention incorporates ultraviolet knife lamps in parallel in the box frame, provides a strip for inserting and supporting the knife on the upper end side, and provides an irradiation opening/closing bottom at the bottom. The above-mentioned problems have been solved by using a suspension support rod for irradiation. The present invention will be described below with reference to the drawings. Reference numeral 1 denotes an ultraviolet irradiation box having a hollow interior and a substantially cubic outer shape. Reference numeral 2 designates a bottom plate guide edge provided in parallel to the side surfaces 3, 3 by bending the lower ends of the side surfaces 3, 3 of the ultraviolet ray irradiation box 1 toward the outside in an L-shaped longitudinal section. Reference numeral 4 designates an opening/closing bottom which has both ends bent into a U-shape and is slidably fitted into the bottom plate guide edges 2, 2, and is formed to have substantially the same dimensions as the bottom surface of the ultraviolet irradiation box 1. Reference numeral 5 denotes an irradiation port drilled in the bottom of the ultraviolet irradiation box 1. Reference numerals 6 and 6 designate knife clamping plates that are pasted on the upper surface 7 of the ultraviolet irradiation box 1 in two parallel rows in the lateral direction with a knife insertion gap 8 provided in the center. Reference numerals 9 and 9 designate ultraviolet sterilizing lamps that are horizontally installed in the ultraviolet irradiation box 1 at positions below the knife holding plates 6 and 6 in two rows parallel to the knife insertion gap 8 with irradiation intervals. Reference numeral 10 denotes a substantially U-shaped gripping rod whose left and right ends are pivotally connected to the left and right side surfaces 11, 11 of the ultraviolet irradiation box 1. 12 is a cord connected to the ultraviolet germicidal lamp 9. (Function) When the present invention is implemented and the knife A is inserted into the knife insertion gap 8 with the ultraviolet germicidal lamps 9 and 9 turned on, ultraviolet rays with a strong germicidal effect are irradiated from both sides of the blade of the knife. The irradiation port 5 opens when the opening/closing bottom 4 is opened. When moved onto the surface, the germicidal ultraviolet rays emitted from the ultraviolet germicidal lamps 9, 9 are irradiated onto the surface of the plate through the irradiation port 5, making it possible to completely sterilize and disinfect harmful bacteria in about 1 to 2 minutes. (Embodiment) A synthetic resin plate or a synthetic rubber plate having elasticity is suitable for the knife holding plate 6. Further, the ultraviolet germicidal lamp 9 is preferably one that emits germicidal radiation having an ultraviolet wavelength of 253.7 nm (nano, meter). The results of the germicidal efficacy test of the UV germicidal lamp 9 are shown below. Sample germicidal lamp name Product name Clean light (SK-6 type) 100V, 6W Manufactured by Showa Tokushu Kogyo Co., Ltd. Test bacteria: Shigella, Salmonella, pathogenic Escherichia coli, Staphylococcus aureus Irradiation distance: 0.5 m (Test bacteria smeared plate medium) (irradiated from directly above) Medium used: Ordinary agar medium (manufactured by Nitsusui)

[Table] Numbers indicate the number of viable and growing bacteria.
(Effects of the invention) When this invention is implemented, strong sterilization can be performed immediately without adding bulk by simply inserting the knife into the ultraviolet irradiation box. When irradiating, just open and close the bottom and the irradiation port will emit strong sterilizing ultraviolet rays, so you can easily hold it in your hand and completely sterilize harmful bacteria in 1 to 2 minutes. This is an idea that will greatly contribute to eradicating food poisoning.
