The present invention relates to a sterilizing dryer, and more particularly, to put on a table or a dining table of a home or the user to directly use a sterilization object or to sterilize household appliances such as scissors, knives and stethoscopes in a beauty salon or a hospital. It relates to a portable sterilization dryer for.

With the recent increase in income levels, interest in hygiene is gradually increasing. Therefore, even when washing dishes such as cutlery and chopsticks, there is an increasing demand for a device for removing various kinds of invisible bacteria as well as simply removing contaminants adhered to the surface.

In particular, such hygiene management is more essential in a restaurant such as a restaurant that is used by an unspecified number of people, and various types of dishwashers have been manufactured for commercial use. These types of cleaners have been proposed to remove only contaminants attached to the surface, a device for sterilizing by heat by applying a high temperature to the tableware, or a device for sterilizing by using an ultraviolet lamp and anion.

However, these devices are all large equipment installed in the kitchen of the shop has a disadvantage that the user using the actual tableware can not directly check the hygiene state of the dishes used by them. In addition, due to the nature of the business, since a large number of used dishes are washed, it is impossible to wash each dish carefully, so that users cannot completely solve anxiety about the sanitary condition of the dishes.

In addition, even if the dishes are completely washed, external bacteria may be attached to the dish during storage for a long time, and the dishes may be contaminated while the user selects the cutlery.

Therefore, in order to solve this problem, a technique of a type in which a sterilization function is added to a cutlery mounted on a table has been proposed.

In other words, Korean Utility Model Registration No. 20-258446 attaches ultraviolet sterilization lamps to cutlery containers used in restaurants and homes to show users how to sterilize tableware and prevent contamination from storage. Disclosed is a cutlery with an ultraviolet germicidal lamp.

The utility model registration is to install a plurality of spoon storage box and chopsticks storage box in the body of the spoon, the ultraviolet lamp is installed inside the body, so that the ultraviolet lamp can be turned on or off according to the opening and closing of the transparent lid part to see the inside The user can take out the sterilized tableware directly.

However, since the utility model registration is stored in a state in which a plurality of spoons and chopsticks are stored in a state in which the spoons and chopsticks are not aligned, there is a disadvantage in not only aesthetic appearance but also cause inconvenience in use. In addition, since only ultraviolet lamps are used as sterilizers, the sterilization effect is insufficient, and the water that gets on the surface of the dishes during the washing process is simply stored in a separate reservoir, so that the hygiene problem is caused by the condition of generating additional bacteria due to the decayed water. There is a fear that occurs, and because the water on the utensils to the user's hand has a disadvantage that may cause the user uncomfortable.

In addition, since the ultraviolet rays irradiated from the ultraviolet lamp is irradiated through the plate as it is, there is also a problem that the ultraviolet rays harmful to the human body is transmitted to the outside as it is through the lid.

On the other hand, Korean Utility Model Registration No. 20-300477 discloses a device for sterilizing the tableware by the heat of steam instead of ultraviolet light. Since the utility model registration does not use an ultraviolet lamp, there is no damage caused by ultraviolet rays, but there is a possibility that a user may be burned due to high temperature water vapor, and there is no separate alignment mechanism in the spoon support, so the problems described above are intact. It is implicated.

In addition, various tools such as scissors, knives, stethoscopes, and ties in beauty salons and hospitals have been found to be mediators that cause secondary infections in customers or patients.These devices can be easily sterilized, disinfected, and reused. There is an increasing demand for appliances, and therefore the mobile sterilization dryer according to the present invention can be used for sterilization drying of household appliances in kitchens or restaurants as well as in beauty salons or hospitals.

Therefore, the blocking plate is preferably a material having high reflectance, and in this embodiment, stainless sus 304 is adopted.

In order to prove the bactericidal effect of the ultraviolet rays by the ultraviolet irradiation part, sterilization experiments were performed for E. coli and Salmonella.

1) Escherichia coli

In general, Escherichia coli is a bacterium that is widely present in our lives, and usually has a great effect on the intestines such as diarrhea. Escherichia coli usually does not show pathogenicity in the intestine, but when it enters other parts of the intestine, it causes cystitis, pyelitis, peritonitis, sepsis, and even in the intestines. It is called Escherichia coli especially because it can cause infectious diarrhea until. In addition, the presence of E. coli is an indicator of the presence of contamination by feces, and is an important hygiene as a means often applied to water quality tests. This suggests that the presence of Escherichia coli is highly likely to exist other bacteria. As a result, many studies have identified the presence of E. coli. In this experiment, the effect of UV sterilization on E. coli was also examined.

First, the sterilized paper was cut to a length of 1 길이 1cm and inoculated with the appropriate bacteria there. This inoculated paper was exposed to UV light directly for 0, 5, 10 minutes in this product to investigate its bactericidal effect. The distance between this unit's UV lamp and the front of the cutlery is 4 cm. The sterilization effect of the first 5 minutes was high at a distance of 4 cm. The number of early E. coli was 2.7 × 10 ⁵ , but after 5 minutes it was reduced to 2.5 × 10 ³ . This showed a 99% strain removal efficiency for the first 5 minutes followed by a steady decrease in E. coli for 10 minutes. However, the sterilizing power for 5 to 10 minutes is slightly lower than the initial 5 minutes. Therefore, it is judged that it is effective not only to extend the service life of the UV lamp but also to save electric charges. [Figure 1] shows the result of incubating E. coli up to the mid-log stage and inoculating 50ul into a sterile square (1cm ² ) and disinfecting with UV light for a suitable time.

[Figure 1] E. coli sterilization effect by UV rays (log ₁₀ value of bacteria according to time)

2) Salmonella

Salmonella is specially administered as a food poisoning bacterium during the summer months, and it is one of the bacteria that causes food poisoning at the same time in several groups or restaurants. In this experiment, we tested with Salmorella as the cause of food poisoning. The experimental method was carried out in the same way as when E. coli was tested, and the results were also summarized in the same manner as shown in [Figure 2].

[Figure 2] Sterilizing Effect of Salmonella by Ultraviolet Rays (log ₁₀ Value of Bacteria with Time)

Figure 3 compares the photo before and after treatment for 5 minutes. Each was treated by attaching the same amount of E. coli or Salmonella on the surface of the cutlery. About 99% of the bacteria were reduced compared to the UV treatment.

[Figure 3] Comparison of germicidal power using UV

The bactericidal effect by ultraviolet light of the present invention showed the maximum effect in about 5 minutes, and the closer the distance was, the greater the effect was confirmed. Accordingly, the design of the present invention allows the ultraviolet lamp to be operated for 5 minutes, and after 5 minutes, the ultraviolet lamp can be flickered to increase the endurance life of the device by saving electricity and extending the life of the ultraviolet lamp. . In addition, the use of stainless reflecting inside allows the ultraviolet light to be evenly distributed throughout the sterilizer. Through this reflection, the ultraviolet light is concentrated in one direction, which shows a more effective sterilization effect.
