Description

Sterilizer for Household Goods

The present invention relates to a sterilizer for household items that is provided at home or in an office so that it can be easily sterilized and sterilized by containing household items. that made it possible

In general, household items used in homes or offices, such as toys, baby products, stationery, etc., are touched by several people, and there is a high risk of bacteria or viruses on the hands growing.

In particular, baby products have a high risk of bacterial propagation for reasons such as small children spilling food or sucking food in their mouth, and for this reason, a separate sterilizer is often provided at home.

As an example, a sterilization storage box for sterilization has been proposed in the Republic of Korea Registration No. 20-0351504 (registration on May 14, 2004), and Public Utility Model No. 20-2013-0001839 (published on March 18, 2013) of the Republic of Korea.

Republic of Korea Registration No. 20-0351504 (Registered on May 14, 2004) installed an ozone generator in a sterilization storage box to have sterilization and disinfection functions, and Republic of Korea Utility Model No. 20-2013-0001839 (published on March 18, 2013) In the case, ultraviolet sterilization lamps are installed inside the sterilization drying box with a sealed cover provided at the top of the drying case, and the four corners are interlocked and stacked.

However, the conventional sterilization cabinets, including the sterilization cabinets as described above, have a problem in that they are too complicated in structure, which increases the manufacturing cost, and thus the price of the products is too high, so that it is difficult to spread them.

In particular, it is very important to implement a UV blocking structure because UV rays, which are mainly used for sterilization of sterilization cabinets, can cause various side effects on the eyes or skin when directly exposed to the human body. Because the structure for the casing is too complicated, the casing structure becomes complicated, and these factors eventually increase the price for finishing.

In addition, since the sterilization principle of the sterilization cabinet is intensively sterilized in the portion directly irradiated with ultraviolet rays, when the storage space is narrow or there are many items to be sterilized, the sterilization efficiency is structurally very low. Alternatives are required.

The present invention is to solve the above problems, and to improve the sterilization efficiency inside the casing without leaking light to the outside while simplifying the casing structure.

The present invention, as a technical idea for achieving the above object, contains a sterilization object in the accommodation space of the storage body, and covers the top of the storage body with a cover equipped with a sterilization lamp, so that the sterilization lamp is turned on in a state in which the accommodation space is blocked. In the sterilizer to be made, the receiving body is made of a dual structure of an inner cylinder and an outer cylinder, a space is formed therebetween, and the cover is a cover body on which a sterilization lamp is mounted and an electric length part mounted on the cover body. It is configured to include a cover body, and the cover has a built-in blower fan, and each of the cover body and the cover body has through holes to introduce outside air into the receiving space of the receiving body, and the receiving body has an inner cylinder exhaust port and an outer cylinder exhaust port. By forming an exhaust flow path so that the air conditioners do not communicate directly with each other but only through the separation space, the air introduced by the blower fan is discharged to the outside through the separation space. it was made to form.

According to the sterilizer for household items of the present invention, although the casing structure of the sterilizer has a double structure, it is made of a simple structure and there is no risk of UV rays emitted from the inside of the accommodation space leaking to the outside, so safe use is possible.

In addition, in addition to the sterilization function by ultraviolet rays, the drying function is further added by inhaling outside air by the double wall construction of the casing and then discharged through the storage space, as well as the inner cylinder 120 and the outer cylinder 140. Since the air is discharged through the spaced apart space, the sterilization efficiency can be optimized by drying and casing insulation, and the sterilization effect can be improved by heating the inside of the sterilization room.

In addition, since the casing structure is simplified, it can be manufactured and supplied at a low cost, and the housing body and cover are designed to close the sterilization distance, and sterilization is started immediately after storing the product. By embedding all the electric parts in the cover, only the storage body in which the object is stored can be separated and washed, so it is possible to use it cleanly.
