Description

Antibacterial door knob for refrigerator {ANTIBIOTIC HANDLE OF REFRIGERATOR DOOR}

The present invention relates to a door handle for a refrigerator, and more particularly to an antimicrobial handle having a sterilization means to sterilize the bacteria on the user's hand in contact with the food to prevent the inflow of bacteria into the refrigerator.

In general, storing food in the refrigerator is to maintain the freshness of the food and to prevent premature decay, but storing the food in the refrigerator does not prevent the bacterial infection of the food.

On the other hand, in order to reduce the bacterial infection of the food stored in the refrigerator, the refrigerator has an antibacterial function. For this purpose, a sterilization means is usually installed in the refrigerator or in an internal duct through which cold air flows. It can also be applied to door gaskets, which are boundary parts. As such sterilization means, photocatalyst antimicrobial agents, which are oxidized by ultraviolet rays in the 300-400 nm band and provide strong sterilizing power, such as titanium oxide, are used.

However, in general, the influence of the sterilization means inside the refrigerator is limited to the inside of the refrigerator, and there is a limit to the sterilization action on foods that are already infected with bacteria. It is known to inhibit but not completely eradicate bacteria.

In addition, the cause of the bacterial infection of the food is mainly caused by the contaminated environment outside the refrigerator, especially since the food is most often infected through the infected hands of the user who comes in contact with the food, it is necessary to be prepared for bacterial infection through the user's hand. It is becoming.

Accordingly, the present invention has been made to solve the problem of the antimicrobial treatment means in the conventional refrigerator described above, in order to contact the door handle of the refrigerator using a photocatalyst to prevent bacterial infection of food through the user's hand. An object of the present invention is to provide an antibacterial door handle for a refrigerator having an improved structure to sterilize a user's hand.

In order to achieve the above object, the antibacterial door handle for a refrigerator according to the present invention applies a photocatalyst to the handle surface, and generates ultraviolet light to inject ultraviolet light into the handle of the refrigerator to generate strong sterilizing power by the oxidation of the photocatalyst. It comprises a switch means for operating the ultraviolet generating means.

The ultraviolet generating means may be configured by selecting among ultraviolet lamps and fluorescent lamps, and embedding the selected ultraviolet generating means in a refrigerator handle. In addition, the ultraviolet generating means may be embedded in the door to irradiate the ultraviolet rays to the refrigerator handle at a position adjacent to the door handle.

Hereinafter, with reference to the accompanying drawings showing an embodiment of the present invention will be described in detail the present invention.

Antibacterial door handle for a refrigerator according to the present invention, as shown in Figures 1 and 2 showing an embodiment, ultraviolet light transmitted through the handle 3 installed in the door 2 of the refrigerator 1 according to the present invention The hollow portion 4 is formed inside the transparent or semi-transparent material which may be formed, and the photocatalyst 4 such as titanium oxide is coated on the surface of the handle 3.

An ultraviolet lamp 6 is disposed in the inner hollow part 5 of the door handle 3 as an ultraviolet generating means, and a control box 7 is built in the door to apply power to the ultraviolet lamp 6. The door surface is provided with an on / off switch 8 for the user to operate the ultraviolet lamp 6 when using the refrigerator.

In addition, instead of operating the ultraviolet lamp 6 directly by adopting the on / off switch 8, when the user stands at a predetermined position in front of the refrigerator to use the refrigerator, it automatically detects the control box 7 The optical sensor 9 may be employed to send a signal to activate the ultraviolet lamp.

Figure 3 shows a door handle employing sterilization means of another embodiment of the present invention. The refrigerator door handle 10 of the present embodiment is coated with a photocatalyst 4 such as titanium oxide on the surface thereof, and from the ultraviolet lamp 6, the control box 7 and the control box to the ultraviolet lamp 6. As in the above-described embodiment of FIG. 2 in that it includes an on / off switch 8 or an optical sensor 9 as switch means for supplying power.

However, in the present embodiment, instead of arranging the ultraviolet lamp 6 inside the refrigerator door handle 10, the part of the door 2 in a position adjacent to the handle is cut off and the ultraviolet lamp 6 and the reflector are mounted therein. The generated ultraviolet rays are arranged to irradiate the handle through the window 11 of transparent or translucent material.

Although the on / off switch 8 and the optical sensor 9 are illustrated as being configured together in FIGS. 2 and 3, only one of the on / off switch and the optical sensor may be configured and shown together for the purpose of description. It is revealed.

In addition, although only the ultraviolet lamp is shown as the means for generating ultraviolet rays in the above-described embodiments, a fluorescent lamp for generating ultraviolet rays may be used instead.

According to the present invention, the photocatalyst is coated on the surface of the door handle of the refrigerator, and when the user wants to use the refrigerator, the ultraviolet light generated by turning on / off the switch or operating an ultraviolet lamp as a signal by a light sensor is applied to the surface of the handle. By irradiating on the photocatalyst coated on the inside, it automatically sterilizes the user's hand holding the door handle of the refrigerator with strong sterilization power by the oxidation action due to the photocatalytic reaction, thereby preventing the bacterial infection of the food through the user's hand that comes in contact with the food. There is an effect that can be easily prevented.
