Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

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.

Under the comprehensive action of the factors, the storage period of the fruits and the vegetables is prolonged, the storage quality is improved, and the marketability is improved.

In one example, the ultraviolet light source 120 is disposed in at least the upper space of the fruit and vegetable cold storage compartment, and has a larger irradiation area, thereby reducing the obstruction of the storage rack. The ultrasonic sound source 110 is at least arranged in the middle space in the fruit and vegetable refrigerating chamber.

The uv light source 120 may be installed in a manner and with a density according to the effective killing range of the uv light. In one example, the light sources 120 are arranged in an array, and the distance between adjacent light sources 120 is 1.5m to 6 m. Further, in one example, the distance between adjacent ultraviolet light sources 120 is 2m to 5 m. In the specific example shown in fig. 1, the distance L between the ultraviolet light sources 120 is 4m in the longitudinal direction, and the distance B between the ultraviolet light sources 120 is 3m in the lateral direction.

The ultrasonic sound source 110 may be set in installation manner and density according to an effective action range of ultrasonic waves. The ultrasonic sound sources 110 are distributed in an array, and the distance between adjacent ultrasonic sound sources 110 is 1.5m to 10 m. Further, in one example, the distance between adjacent ultrasonic sound sources 110 is 3m to 7 m. In the specific example shown in fig. 1, the distance L between the ultrasonic sound sources 110 is 4m in the longitudinal direction, and the distance B between the ultrasonic sound sources 110 is 3m in the lateral direction.

In one example, a storage rack for storing fruits and vegetables is arranged in the fruit and vegetable refrigerating chamber, and the storage rack is made of metal materials. The metal material is very beneficial to the transmission of the ultrasonic wave, so that the transmission effect of the ultrasonic wave in the refrigerator is excellent, and the ultrasonic effect is improved.

In one example, the fruit and vegetable refrigeration, sterilization and insect prevention apparatus 100 further includes a control device 130, the control device 130 is electrically connected to the ultrasonic sound source 110 and the ultraviolet light source 120, and the control device 130 controls the ultrasonic sound source 110 and the ultraviolet light source 120 to be turned on or off simultaneously at regular time. So, can be in personnel's rest time like open equipment preset time at night, the disinfection deinsectization process has been accomplished to personnel during operation, and ozone has decomposed, neither influences work, does not need loaded down with trivial details operation again.

The invention also provides a fruit and vegetable refrigeration sterilization insect prevention method, which comprises the following steps:

an ultrasonic sound source 110 and an ultraviolet light source 120 are installed in the fruit and vegetable refrigerating chamber, ultrasonic waves generated by the ultrasonic sound source 110 are transmitted in the internal space of the fruit and vegetable refrigerating chamber, and ultraviolet rays emitted by the ultraviolet light source 120 irradiate the internal space of the fruit and vegetable refrigerating chamber.
