It will be understood that when an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, the fruit and vegetable refrigerating, sterilizing and insect preventing device 100 according to an embodiment of the present invention includes a fruit and vegetable refrigerating chamber, and an ultrasonic sound source 110 and an ultraviolet light source 120 disposed in the fruit and vegetable refrigerating chamber, wherein the ultrasonic sound source 110 is configured to generate ultrasonic waves to propagate in an inner space of the fruit and vegetable refrigerating chamber, and the ultraviolet light source 120 is configured to emit ultraviolet light to irradiate the inner space of the fruit and vegetable refrigerating chamber.
Because the ultraviolet ray has strong lethality to the organism, but in the fruit vegetables freezer, because the sheltering from of storing the frame, be unfavorable for the propagation of ultraviolet ray, receive the influence to the effect of killing of pest. According to the fruit and vegetable refrigeration sterilization insect-prevention device 100, the pests are panic and uneasy, the destructive power is lost, the pests are unconsciously kept away from ultraviolet rays, the vitality is weakened, and the pests are killed and killed by ultraviolet irradiation in the fruit and vegetable refrigeration chamber through ultrasonic waves. Through the combined action of the ultrasonic waves and the ultraviolet rays, the time for killing pests is shortened, the efficiency is improved, and the pest damage degree of fruits and vegetables is reduced. Meanwhile, the ultraviolet rays can irradiate and kill mould or bacteria in the fruit and vegetable refrigerating chamber, so that the fruit and vegetable are prevented from going mouldy and rotten.
The ultraviolet ray can also be used for introducing partial oxygen (O) into the refrigerating chamber2) Conversion to ozone (O)3)，Therefore, oxygen components in the refrigerator are reduced, on one hand, respiration of fruits and vegetables can be inhibited, the service life of the fruits and vegetables is prolonged, on the other hand, generated ozone enters the fruit and vegetable box along with cold air in the refrigerator, and the effect of killing germs, viruses and pests in the box can be achieved.
In addition, the disturbance effect of the ultrasonic wave can also lower the freezing point of water and the cold damage point of fruits and vegetables.
