Abstract
The photocatalyst and negative ion sterilized refrigerator includes cold storage and negative ion photocatalyst coating painted to at least one of inner surface of the cold storage, the surface of shelf, the inner surface of the door or outer surface of the fruit and vegetable chamber. Owing to the negative ion photocatalyst coating, low concentration ozone, great amount of sterilizing negative ions, powerful sterilizing hydroxyl radicals and other sterilizing ions may be produced inside the refrigerator under the irradiation of ultraviolet or visual light to sterilize the matters inside the refrigerator.
Description
Technical field
The present invention relates to a kind of sterilization refrigerator, relate in particular to a kind of photocatalyst anionic sterilization refrigerator.
Background technology
Cold compartment of refrigerator is mainly used to deposit fruit and vegerable, fresh food, leftovers leftovers etc.As everyone knows, the indoor temperature of refrigerator cold-storage is lower, and generally between 0 ℃-10 ℃, because temperature is lower, so activation of microorganism obviously reduces, food spoilage speed obviously slows down, and therefore, refrigerator has obtained quoting widely in current society.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 grow at 0 ℃-7 ℃, and in 7-10 days, produce the microorganism of 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, and they are just very vigorous 7 ℃ of growths 3-5 days.For kill bacteria and mycete, people install adsorbent equipment in refrigerator, with the absorption stink, but adsorbent equipment cuts little ice to antibacterial, mycete on the food in inner container of icebox surface and the refrigerator, it just adsorbs the stink of microorganisms, and is inoperative to food preservation.In recent years, people add antibacterial again in the plastics that inner container of icebox, door handle etc. is located, form present popular antimicrobial refrigerator, but this kind antimicrobial refrigerator can only be killed inner container of icebox, door handle etc. and locates lip-deep antibacterial, be the contact sterilization, then inoperative to the antibacterial on the food.In recent years, refrigerator industry using ozone generator is again killed antibacterial 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 is difficult for accepting, therefore, this kind mode is not applied in the refrigerator industry.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of photocatalyst anionic sterilization refrigerator, to kill antibacterial on the article and mycete in the refrigerator effectively, prolong the fresh keeping time of food in the refrigerator.
In order to achieve the above object, technical program of the present invention lies in having adopted a kind of photocatalyst anionic sterilization refrigerator, comprise 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 negative ion photocatalyst, form negative ion photocatalyst and film.
Described negative ion photocatalyst is filmed by TiO
2The neutral liquid spray made from the nanometer grade powder of piezoquartz tourmaline forms.
Supersonic generator also is installed in cold room.
The ultraviolet and ozone generating means also is installed in cold room.
Owing in the inner surface and fruit and vegerable outdoor face of the inner bag surface of the cold room of refrigerator of the present invention, shelf surface, door, have at least a place to scribble one deck negative ion photocatalyst, and negative ion photocatalyst is TiO
2The neutral liquid spray made from the nanometer grade powder of piezoquartz tourmaline forms, it and common nano-TiO
2Difference be, it contains piezoquartz, except that character with photocatalyst, under the effect of faint luminous energy, mechanical energy, acoustic energy etc., can produce a large amount of anion with sterilizing function, as spraying negative ion photocatalyst on the indoor wall, the anion in the room air can reach 1600/cm
3, sterilizing rate reaches 99.99%.During work, under the irradiation of ultraviolet or illuminating lamp, will produce the ozone of low concentration in the refrigerator, have an anion of bactericidal action and have sterilization such as the hydroxy ion of very strong bactericidal action in a large number, thereby the article in the refrigerator will be sterilized.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the present invention;
Fig. 2 is the structural representation of another embodiment of the invention;
Fig. 3 is the structural representation of the third embodiment of the present invention;
Fig. 4 is the structural representation of Fig. 3 middle-ultraviolet lamp ozone generating-device.
The specific embodiment
As shown in Figure 1, photocatalyst anionic sterilization refrigerator of the present invention is by 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, cold room lamp 10, inner bag surface at cold room 2, the surface of cold room shelf 8, the outer surface of the inner surface of refrigerating-chamber door 4 and fruit and vegerable chamber 13, all scribble one deck negative ion photocatalyst and film 12, negative ion photocatalyst film 12 can be when opening the door the light in the external world, or the houselights in the cold room 2 excites and produces the anion with bactericidal action and have sterilization such as the hydroxy ion of very strong bactericidal action, make in the cold room 2 and be full of anion, just can control the time that anion and other sterilization ion produces by the working time of control illuminating lamp, thereby control the sterilizing time of refrigerator.
Embodiment 2
As shown in Figure 2, the difference part of present embodiment and embodiment 1 is: increased a supersonic generator 11 in cold room 2, when refrigerating-chamber door 4 is closed, without illuminating lamp, but start supersonic generator 11, excite negative ion photocatalyst 12 work of filming with acoustic energy, to produce a large amount of anion, control hyperacoustic working time and just can control the generation of anion in the cold room, thereby control sterilizing time.
As Fig. 3, shown in Figure 4, photocatalyst anionic sterilization refrigerator of the present invention is by 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, cold room lamp 10, fruit and vegerable chamber 13, in cold room 2, increased by a ultraviolet and ozone generating means 14, ultraviolet and ozone generating means 14 is by box body 15, the quartz burner 16 that an end is installed in the box body 15, the miniature electric fan 17 that the other end is installed in the box body 15 constitutes, scribble negative ion photocatalyst on box body 15 inner surfacies and film 12, be installed with exhaust vent 18 and fresh air inlet 19 on the both ends of the surface of box body 15 respectively, dark slide 20 is installed in the end face of quartz burner 16 sides, dark slide is made of the dividing plate that evenly is installed with air-vent, air-vent 21 on the dark slide 20 and with its over against end face on fresh air inlet 19 or exhaust vent 18 stagger mutually, the blocking ultraviolet.When quartz burner 16 work, ultraviolet radiation is filmed on 12 to negative ion photocatalyst, negative ion photocatalyst is filmed and 12 will be discharged a large amount of anion under action of ultraviolet ray, and produce the extremely strong hydroxy of sterilizing power, meanwhile, under ultraviolet irradiation, airborne part oxygen will change ozone into, these sterilization ions are derived ultraviolet and ozone generating means 14 by mini-fan 17, and are distributed in the whole cold room 2, and food is sterilized.
