Description
Technical field
The invention belongs to technical field of semiconductor illumination field, particularly a kind of multifunctional refrigerator illuminator.
Background technology
Along with the development of modern technologies, the raising of people's living standard, refrigerator becomes an indispensable part in people's life, but nowadays people are also also more and more higher to the functional requirement of fridge freshness retaining, sterilization and deodorizing.The fresh-keeping measure of general refrigerator is the respiration being suppressed vegetables and fruits by low temperature, or removes the ripening gas in vegetables and fruits by active carbon, catalyst etc., delays the maturation time of vegetables and fruits, thus keeps the freshness of vegetables and fruits.But the freshness date of vegetables and fruits only has 3 days, be difficult to meet people to fresh-keeping requirement.Only green plants carries out the indispensable necessary condition of photosynthesis, and photosynthesis is the summation that green plants carries out the metabolic response of series of complex, is the basis that living nature is depended on for existence, is also the important medium of earth carbon oxygen cycle.Fresh-keeping by photosynthesis is that one is different from the freezing anticorrosion and fresh-keeping mode of chemical substance corrosion-resistant of tradition.Occurred the fresh-keeping refrigerator of many employing photosynthetic antistaling modes in the market, but these light sources lack specific aim, can not carry out the illumination of different colours and duration, thus cannot reach the fresh-keeping effect of expection to vegetables and fruits.
Patent CN200620016857.3 discloses a kind of fresh-keeping refrigerator, have employed and promotes the photosynthetic smooth preservation device of fruits and vegetables, be made up of light emitting source, control panel and mount pad.Although the refrigerator of this patent Introduction adopts purple or lamp group that is blue or orange or red to prolong storage period, can not to suppress in refrigerator the microbial growths such as bacterium, this also can have influence on the food materials freshness in refrigerator, affects fresh-keeping effect.
A lot of technology is had to may be used for eliminating the bacterium in air, as chemical sterilization, ozone sterilization, traditional low pressure mercury lamp ultraviolet illumination sterilization etc.Chemical sterilization technology utilizes chemical reagent to carry out sterilization, and chemical reagent easily remains in the surface of object, and the harmful substance of generation is not easy degraded, all brings potential harm to human body and environment; Ozone sterilization technology be utilize high voltage excite atmospherical discharges produce ozone, ozone with the structure of the oxidation destroy microorganisms film of oxygen atom to realize bactericidal action; The principle of ultraviolet-sterilization is that the energy of ultraviolet photon is absorbed by the base-pair in DNA, causes inhereditary material to morph, and makes bacterium dead or irreproducible at once, thus reaches the object of sterilization.First two mode is not obviously suitable for refrigerator environment, and ultraviolet-sterilization technology then can be used for carrying out sterilization to the space in refrigerator.Conventional ultraviolet source is low pressure mercury lamp, utilizes low-pressure mercury vapor electric discharge to produce ultra-violet radiation.But adopt in refrigerator low pressure mercury lamp to there are some shortcomings: one be the discharging substance mercury of low pressure mercury lamp is a heavy metal species, as breakage leak after very large to the harm of human body, be also unfavorable for after glass lamp breakage repairing and safeguard; Two is that switch refrigerator doors makes low pressure mercury lamp frequent starting, shortens the life-span.
Patent CN200920238236.3 discloses a kind of refrigerator with magnetic field optical wave sterilization fresh-keeping device, in top or the side of inner container of icebox, is fixed with magnetic field optical wave sterilization fresh-keeping device by screw or screens.Although have excellent bactericidal effect, it adopts ozone sterilization, and residual ozone is larger to harm.
In addition, after refrigerator uses for a long time, the bacterium in the food of storage can breed and produce organic compound on the inner bag of refrigerator and shelf thereof, causes producing stink in refrigerator.In order to solve problem above, inner container of icebox or shelf add anti-biotic material, can the breeding of anti-bacteria on inner bag and shelf effectively, but can not deodorizing; Employing is added adsorption plant and is realized adsorbing the stink in refrigerating chamber in the refrigerating chamber of refrigerator, but the sorbing material in adsorption plant is easily saturated, can not carry out permanent deodorizing, changes also inconvenient.
Patent CN200410010041.5 discloses a kind of optical catalyst negative ion sterilizing refrigerator, and this refrigerator adopts the mode of ultra violet lamp to produce ozone, then to be dispelled in refrigerating chamber by the anion that anion generator produces with fan and carry out sterilization and deodorizing.Refrigerator described in this patent utilizes the ozone of generation and anion to carry out degerming deodorizing, both combinations improve the degerming of refrigerator and deodorizing effect, but there is ozone residue problem in this method, and need the equipment such as anion generator, uviol lamp, miniature circulating fan, shadow shield, make that odor removal parts are various, complex structure, add the manufacturing cost of deodorization and sterilization device.
