On the inner surface of the box of the comprehensive sterilizing device, negative ion photocatalyst is painted, which is formed through spraying neutral liquid with nanometer TiO2 and piezoelectric crystal tourmaline powder and has photocatalyst property and can generate great amount of sterilizing negative ions under the action of weak light energy, mechanical energy, sound energy, etc. For example, negative ion photocatalyst painted on indoor wall can reach negative ion concentration in the indoor air up to 1600/cu cm and sterilizing rate up to 99.99 %.
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, the comprehensive sterilizing unit that can produce ozone, hydroxy and anion is installed in cold room.
Described comprehensive sterilizing unit is by box body, the miniature electric fan that the other end is installed in the quartz burner that an end is installed in the box body, the box body constitutes, scribble the negative ion photocatalyst film on the cartridge inner surface, be installed with exhaust vent and fresh air inlet on the both ends of the surface of box body respectively, in the end face of quartz burner side, dark slide be installed.
Described negative ion photocatalyst is filmed by TiO
2The neutral liquid spray made from the nanometer grade powder of piezoquartz tourmaline forms.
Described dark slide is made of the dividing plate that evenly is installed with air-vent, the air-vent on the dark slide and with its over against end face on fresh air inlet or exhaust vent stagger mutually, the blocking ultraviolet.
The miniature electric fan that the other end is installed in the quartz burner that described comprehensive sterilizing unit is installed by an end in box body, the box body, the box body constitutes, and scribbles TiO on the cartridge inner surface
2The photocatalyst film is installed with exhaust vent and fresh air inlet respectively on the both ends of the surface of box body, in the end face of quartz burner side dark slide is installed, and anion generator also is installed in box body.
Described dark slide is made of the dividing plate that evenly is installed with air-vent, the air-vent on the dark slide and with its over against end face on fresh air inlet or exhaust vent stagger mutually, the blocking ultraviolet.
The comprehensive sterilizing unit that can produce ozone, hydroxy and anion is installed in the cold room of refrigerator of the present invention, scribbles the negative ion photocatalyst film on the cartridge inner surface of comprehensive sterilizing unit, 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 a structural representation of the present invention;
Fig. 2 is the structural representation of first kind of embodiment of comprehensive sterilizing unit among Fig. 1;
Fig. 3 is the structural representation of second kind of embodiment of comprehensive sterilizing unit among Fig. 1.
The specific embodiment
As Fig. 1, shown in Figure 2, photocatalyst anionic sterilization refrigerator of the present invention, comprise 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 and fruit and vegerable chamber 13, in cold room 2, be equipped with and produce ozone, the comprehensive sterilizing unit 11 of hydroxy and anion, comprehensive sterilizing unit 11 is by box body 17, the quartz burner 16 that an end is installed in the box body 17, the miniature electric fan 18 that the other end is installed in the box body 17 constitutes, scribble negative ion photocatalyst film 19 on box body 17 inner surfacies, be installed with exhaust vent 20 and fresh air inlet 12 on the both ends of the surface of box body 17 respectively, in the end face of quartz burner 16 sides, dark slide is installed, dark slide is made of the dividing plate 15 that evenly is installed with air-vent 14, air-vent 14 on the dark slide and with its over against end face on fresh air inlet 12 or exhaust vent 20 stagger mutually, the blocking ultraviolet.When quartz burner 13 work, ultraviolet radiation is to negative ion photocatalyst film 19, negative ion photocatalyst film 19 will discharge 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 comprehensive sterilizing unit 11 by miniature electric fan 18, and are distributed in the whole cold room 2, and food is sterilized.
