These concavees lens are to show as concavees lens to deviate from the structure that ultraviolet light source outwards protrudes; Or
These concavees lens are to show as the structure that concave mirror caves inward towards ultraviolet light source.
These concavees lens are arranged on the top of parcel tray, and ultraviolet light source is arranged on the parcel tray top, and its light spreads by concavees lens, increases the degerming scope in the parcel tray.
This parcel tray comprises parcel tray body, storing lid, and these concavees lens are arranged on parcel tray and cover, and is the part of storing lid; These concavees lens are the structure that both sides cave inward; Or these concavees lens are the structure of upside to lower recess; Or these concavees lens are the upwards structure of depression of downside.
The open end of these concavees lens on parcel tray can be rectangle.
These concavees lens can be arranged on the mid portion of storing lid.
When this parcel tray is used for refrigerator, can be placed on the refrigerator shelf, ultraviolet light source is installed in the lower surface of the refrigerator shelf on the top of parcel tray.
This parcel tray dead ahead can be provided with handle.
Owing to adopted such scheme, the utlity model has following characteristics: ultraviolet of the present utility model is by the concave lens structure more effective irradiation, need not to use catalytic specie, only by ultraviolet ray, just can realize sterilization and the catabolite that neither generate to be harmful to, can reduce the effect of remains of pesticide on the food safely again with simple structure and cheap expense.

The specific embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
The utility model mainly is the ultraviolet wavelength of the utilizing ultraviolet light source (light of scope of 240nm～400nm) for example, degerming on the one hand, can cut off the strand of remains of pesticide on the food in addition, finally decompose, reduce harmful chemical property with low-molecular-weight.
The utility model ultraviolet sterilization device, it comprises ultraviolet light source, parcel tray, this ultraviolet light source is arranged on around the parcel tray so that its light is irradiated in the parcel tray.It also comprises concave lens structure, and this concave lens structure is arranged between the space in ultraviolet light source and the parcel tray, and the light that ultraviolet light source sends can be assembled by concave lens structure, spread with increase the effective range of exposures in the parcel tray.
As shown in Figure 1, the utility model can be applicable to refrigerator, the applied refrigerator of present embodiment is to comprise refrigerator body 1 inside that the refrigerator body 1 of open at its front and the refrigerating chamber 3 that can open and close and refrigerating chamber 2 are formed and refrigerating-chamber door 2a and the refrigerating chamber door 3a that is arranged on the front, the compressor that also comprises the formation circulation that is arranged on basifacial Machine Room behind the refrigerator that does not mark among the figure, condenser, expansion valve, electric fitting parts such as evaporimeter also comprise in order to supply with the shelf 4 that from the evaporimeter the cold air of heat exchange is transported to the tap hole 5 of refrigerating chamber 2 and places chilled food.
Because of the lower inside temperature contrast of refrigerating chamber 2 is little, can keep suitable temperature and humidity, so, parcel tray 10 is arranged on this locus in order to preserve fresh vegetables and fruit.
In order to make the ultraviolet ray of parcel tray 10 internal irradiations in the sunlight line, ultraviolet light source 20 is by connecting the lower surface that attached material 4a is arranged on shelf 4, promptly on the top of parcel tray 10.
Because of ultraviolet light source 20 is arranged on the downside of shelf 4, if do not go painstakingly to watch, it is attractive in appearance unaffected.
As shown in Figures 2 and 3, parcel tray 10 its inboard formation of the present utility model can be held the storage area of vegetables and fruit, and it also comprises the parcel tray body 11 of the hexahedron image that a side is open and for opening and closing the storing lid 15 that parcel tray body 11 opening portions dispose.
The dead ahead of parcel tray body 11 is provided with the handle 12 of promising mobile parcel tray 10, can move forward and backward according to user's purposes bar storage box 10.
The center of the storing lid 15 that is provided with in the opening portion of parcel tray 10 is with length direction (or width, or other help the direction that light that ultraviolet light source 20 discharges spread parcel tray 10 in) formation concavees lens 16, promptly, the open end of concave mirror on parcel tray can be rectangle, light diffusion more in large area in parcel tray 10 that the ultraviolet light source 20 that is arranged on the parcel tray 10 is discharged.
These concavees lens 16 form with the concavity flexing respectively in the upper surface and the lower surface of storing lid 15, because both sides all cave inward up and down, its central portion is thinner than two side peripheries, is rendered as the band shape of depression, can effectively spread light.
The light that comes out from ultraviolet light source 20 radiation is by the concavees lens 16 on the storing lid 15, enlarge the irradiating angle of ultraviolet light source lamp20, make the diffusion inside of light at parcel tray 10, need not to use other catalytic species, only just can reduce residual agricultural chemicals on the food such as fruit or vegetables safely with ultraviolet ray.
As shown in Figure 4, another embodiment of the present utility model is arranged on the concavees lens 16a on storing lid 15 tops, be in following side, the top of storing lid 15 always the concavity flexing form, its central portion is thinner than two peripheries, and light is spread.
As shown in Figure 5, perhaps being arranged on the concavees lens 16b of the bottom of storing lid 15, is always concavity flexing formation in above side, the bottom of storing lid 15, and its central portion is thinner than periphery, can make the light diffusion.Also can cover the flexion angle variation of the concavees lens 16 that form on 15 by bar storage box, thereby make the irradiating angle variation of ultraviolet light source 20.
Present embodiment is to illustrate with the concavees lens 16 that form on ultraviolet light source 20 that is provided with on the top of refrigerator parcel tray 10 and the storing lid 15, but also can use food such as kraut refrigerator or keeping vegetables and fruit with other devices that reduce remains of pesticide on it on.
