Abstract

The utility model relates to a refrigerator with the disinfection function. The refrigerator with the disinfection function comprises a refrigerating chamber, a disinfecting device is arranged in the refrigerating chamber, and in internal bladder surfaces of the refrigerating chamber, isolating rack surface, inner surfaces of a door and outer surfaces of a fruit and vegetable chamber, at least one place is provided with a layer of light catalysts to form a light catalyst coating film. When the disinfection to the articles in the refrigerating chamber is needed, an ultraviolet lamp works, when the ultraviolet lamp works, the ultraviolet is radiated on the articles to disinfect the articles in the refrigerating chamber, simultaneously, the ultraviolet is radiated on the light catalysts on the surface of the refrigerating chamber, high effect disinfecting ions-hydroxy radicals and a large amount of negative ions with the disinfecting function are generated, and accordingly, the omnibearing disinfection to the articles in the refrigerator is done.

Description

A kind of refrigerator with disinfection function

Technical field

This utility model relates to a kind of refrigerator, relates in particular to a kind of refrigerator with disinfection function.

Background technology

The extensive use of refrigerator has brought a lot of convenience for people's life, but refrigerator is not a condom, the food of in refrigerator, depositing, and especially the food of depositing at cold room still wants corrupt.According to microbiologist and the research of Food Science man, food spoilage is mainly caused by antibacterial and mycete.The kind of antibacterial is a lot, the ambient temperature difference of different bacterial growth breedings for cold-adaptive microbe bacterium strain, can be grown at 0 ℃-7 ℃, and the microorganism that in 7-10 days, produces visible bacterium colony, in 0 ℃ of-5 ℃ of scope, can cause the putrid microorganism of meat, poultry and vegetable can be considered to cold-adaptive microbe bacterium strain.Typical cold-adaptive microbe bacterium strain is mould real pseudomonas and Aeromonas hydrophila, they under 7 ℃ temperature, grow 3-5 days also very vigorous.For kill bacteria and mycete, people install adsorbent equipment in refrigerator, with the absorption stink, but adsorbent equipment to the antibacterial on the food in inner container of icebox surface and the refrigerator, mycete without any effect, the stink that just adsorbs microorganisms, in fact inoperative to shelf life storage and human beings'health.In recent years, in the plastics that inner container of icebox, door handle etc. is located, add antibacterial again, form present popular antimicrobial refrigerator, but this kind refrigerator can only be killed lip-deep antibacterials such as inner container of icebox, door handle, be the contact sterilization, inoperative to the antibacterial on the food.Recent years, ozonator is applied in the antibacterial of killing on the refrigerator in the refrigerator, ozone is a kind of efficient sterilizing material, can kill the antibacterial on the food in the refrigerator, but harmful when concentration is higher, and stink is heavier, and the user does not accept, therefore, never applied in the refrigerator industry.

The utility model content

The purpose of this utility model is to provide a kind of refrigerator with disinfection function, to kill the antibacterial mycete in the refrigerator, prolongs the fresh keeping time of food.

In order to achieve the above object, the technical solution of the utility model has been to adopt a kind of refrigerator with disinfection function, comprise cold room, be provided with a sterilizing unit in the cold room, in the inner surface and fruit and vegerable outdoor face of the inner bag surface of cold room, shelf surface, door, have at least a place to scribble one deck photocatalyst, form photocatalyst and film.

Described sterilizing unit can be ozonator, anion generator, plasma generator, ozone anion generator and/or ultraviolet lamp group.

Described photocatalyst is filmed and can be filmed for the nano titanium oxide photocatalyst, also can film for the anion nanometer photocatalyst of titanium dioxide.

Because on the inner bag surface of cold room, the inner surface of shelf surface, door, have at least a place to scribble one deck photocatalyst, form photocatalyst and film.When need be to the sterilisation of objects in the cold room, uviol lamp work, during uviol lamp work, ultraviolet radiation carries out sterilizing to the article in the cold room to object, simultaneously, ultraviolet also shines on the photocatalyst of cold room inner surface, can produce potent sterilization ion---and hydroxy reaches has the anion of bactericidal action in a large number, thereby the article in the refrigerator are carried out omnibearing sterilizing.

The specific embodiment

Embodiment 1

As shown in Figure 1, refrigerator of the present utility model comprises refrigerating chamber 1, cold room 2, refrigerating chamber door 3, refrigerating-chamber door 4, refrigerator evaporator 5, freezer evaporator 6, cold chamber drawer 7, cold room shelf 8, water receiving tank 9.The sterilizing unit that is provided with in cold room 2 is a Burdick lamp 10, at the inner bag surface of cold room 2, the surface of cold room shelf 8, the inner surface of refrigerating-chamber door 4, all scribbles one deck anion nanometer photocatalyst of titanium dioxide and films 11.Cold room 2 both can also can be used as cold room as sterilization chamber, when need be to the sterilisation of objects in the cold room 2, Burdick lamp 10 work, during Burdick lamp 10 work, ultraviolet radiation carries out sterilizing to the article in the cold room 2 to object, simultaneously, ultraviolet also shines the anion nanometer photocatalyst of titanium dioxide 11 of cold room 2 inner surfacies, produces potent sterilization ion---and hydroxy reaches the anion that has bactericidal action in a large number; Under the effect of Burdick lamp 10, also produce ozone in the cold room 2, thereby comprehensively sterilize at dual-purpose chamber formation ultraviolet, ozone, anion with strong bactericidal action.

Embodiment 2

As shown in Figure 2, the difference of present embodiment and embodiment 1 is, the sterilizing unit that is provided with in cold room 2 is Burdick lamp 10 and anion generator 12, anion generator 12 the negative ion concentration that has improved in the cold room 2 is set, strengthened disinfection effect.

Claims

1, a kind of refrigerator with disinfection function, comprise cold room, it is characterized in that: be provided with a sterilizing unit in the cold room, in the inner surface and fruit and vegerable outdoor face of the inner bag surface of cold room, shelf surface, door, have at least a place to scribble one deck photocatalyst, form photocatalyst and film.

2, the refrigerator with disinfection function according to claim 1 is characterized in that: described sterilizing unit can be ozonator, anion generator, plasma generator, ozone anion generator and/or ultraviolet lamp group.
