Background technology

Usually, refrigerator comprises refrigerating chamber and refrigerating chamber.An ad-hoc location in refrigerating chamber is provided with the vegetables compartment in addition, thereby vegetables and fruit are stored under the fresher state.

Several factors influences the freshness of vegetables, for example temperature, humidity, environmental gas, microorganism, light etc.Because vegetables ceaselessly breathe and transpiration, therefore need to suppress breathing and transpiration to keep vegetables fresh.Except that some can not be in vegetable species under the low temperature, the respiration of most of vegetables was suppressed at low temperatures, and transpiration is suppressed under high humility.

For this reason, refrigerator is provided with to have and the refrigerating chamber vegetables compartment in space independently, thereby vegetables are stored under the fresh state for a long time.The vegetables compartment remained under the suitable low temperature and high as far as possible humidity under.In other words, keep the temperature and humidity in the vegetables compartment suitably, so that the vegetables in the vegetables compartment are remained on the height fresh state.

Simultaneously, seeking a kind of making uses up (another influence factor relevant with the freshness of vegetables) and keeps the fresh method of vegetables.Stronger light has the color change of promotion vegetables and the negative effect of transpiration relatively, and more weak light has the effect of improving fresh-keeping of vegetables relatively.In addition, the low light level suppresses the chlorophyll degradation of green vegetable and stem dish, and has the ascorbic effect of maintenance.

With reference to Fig. 1 a kind of conventional refrigerator that makes the vegetables compartment of using up that has is described below.

Conventional refrigerator shown in Fig. 1 is a kind of refrigerator that is disclosed among the open No.9-28363 of Japan Patent.Refrigerator 10 is provided with to vegetable box 20 irradiation irradiation with weak light devices 23, thereby the chlorophyll concentration that prevents green vegetable and stem dish reduces, and therefore prevents the debase of green vegetable and stem dish.

The refrigerator of another embodiment according to the present invention is described with reference to Figure 11 and 12 below.

This embodiment relates to the mounting structure of light source 230.The mounting structure of this embodiment can be applied to all above-mentioned embodiments, is particularly useful for spot light.

When light source 230 was installed on the vegetable box 210a, luminous efficiency was higher.But it is inconvenient that light source 230 is installed on the vegetable box 210a.This is because the connection of electric wire is very complicated when light source 230 is installed on the vegetable box 210a.Therefore, with regard to light source 230 was installed, the inwall that preferably light source 230 is installed on the vegetables compartment was on the dividing plate of refrigerator.Because the top of vegetable box 210a is normally open, so it is unaffected to be installed on the luminous efficiency of light source 230 on vegetable box 210a top, but the luminous efficiency that is installed on the light source 230 at front portion, sidepiece or rear portion may reduce.Therefore this is not to be made by complete material transparent because of vegetable box 210a usually, is installed on the light that the light source 230 in the vegetable box 210a outside sends and can not passes completely through vegetable box 210a.This embodiment addresses the above problem.

Referring to Figure 11, light source 230 is installed on the inwall of vegetables compartment, for example on the rear surface of vegetables compartment.That is to say that light source 230 is installed on the rear bulkhead 430 of refrigerator highlightedly, and vegetable box 210a have the hole 212 corresponding with light source 230.When vegetable box 210a put into the vegetables compartment, light source 230 inserted in the hole 212 of vegetable box 210a, and hole 212 is blocked.Therefore, vegetable box 210a keeps sealing state.

Figure 12 shows the similar alternative arrangements of light source 230.

As shown in Figure 12, light source 230 is installed on the rear bulkhead 430 of refrigerator, and vegetable box 210a has the light scattering member 260 corresponding with light source 230.The light scattering that light scattering member 260 sends light source 230, thus light is distributed on the vegetables that store among the vegetable box 210a equably.Vegetable box 210a also has the relative reflecting plate 262 of position and light scattering member 260.By light is reflected with reflecting plate 262, can make light directive vegetables more equably.

Light scattering member 260 and reflecting plate 262 can form with vegetable box 210a, perhaps form independently with vegetable box 210a.In addition, the size of light scattering member 260 and reflecting plate 262 is not limited to concrete value, can suitably change.When light scattering member 260 and reflecting plate 262 occupy vegetable box 210a a part of, preferably change the transmissivity of vegetable box 210a appropriate section, thereby the light that makes light source 230 send can be distributed in more equably among the vegetable box 210a.

The refrigerator of another embodiment according to the present invention is described with reference to Figure 13 to 16 below.

Refrigerator 100 comprises: fuselage 14, and this fuselage has refrigerating chamber; And be in the refrigerating chamber of fuselage 14, be used for the reservoir vessel 200 of storage food.Reservoir vessel 200 comprises: be installed on the main body 10 in the refrigerating chamber, this main body has apotheca 11 and insertion parts 13; Be installed in the insertion parts 13 of main body 10 and towards the luminous irradiation unit 20 of apotheca 11; And the insertion parts 13 of protection main body 10 and can see through the transmissive member 30 of the light that irradiation unit 20 sends.

Main body 10 has the effect of serving as food conservation container, and it is in the bottom of refrigerator.Main body 10 has apotheca 11, and this apotheca is formed by lower wall and left and right sides sidewall.Preferably, main body 10 has a plurality of apothecas 11, is used for storing respectively with the food classification and with the food of classifying.

Sliding-type Storage Box 15 is coupled to the apotheca 11 of main body 10, food is put into Storage Box 15 or take out from Storage Box 15 being convenient to.Yet the device of storage food is not limited to the sliding-type Storage Box 15 of this embodiment, but can be revised as multiple other form, for example with the door of the upper articulation of main body 10.

In order to prevent the moisture leakage, main body 10 and the Storage Box 15 preferably made can remain under the airtight conditions.By the airtight construction of main body 10 and Storage Box 15, can keep enough humidity for a long time by the moisture that distributes in the food.

Main body 10 can have a plurality of apothecas 11.In this embodiment, as shown in Figure 15 and 16, reservoir vessel 100 is made up of a plurality of apothecas 11, and these apotheca in the vertical directions are cut apart.At least one apotheca 11 has temperature-adjusting device 17, so that optionally store meat or vegetables.

Insertion parts 13 is formed on the inner surface of main body 10.Insertion parts 13 is open towards apotheca 11, and irradiation unit 20 is installed in the insertion parts 13 in the mode of inserting.

By irradiation unit 20 is installed in the insertion parts 13 of main body 10 with inserting, in the time of can preventing irradiation unit 20 owing to Storage Box 15 slips and the collision of food damage.

Irradiation unit 20 comprises substrate 21, and is installed on the light-emitting component 23 on the substrate 21.Preferably, the light emitting diode (LED) that the heating of light-emitting component 23 usefulness is relatively low, luminous efficiency is higher is relatively realized.By using LED in this embodiment, the heating of irradiation unit 20 can be minimized, and can improve operational efficiency as light-emitting component 23.

Irradiation unit 20 sends the light of visible region in apotheca 11.The installation site of irradiation unit 20 without limits.Irradiation unit 20 can optionally be installed on the upper and lower of apotheca 11 or the outer surface of apotheca 11.

As a reference, visible light refers to the light of wavelength in about 380 to 770nm scopes, and it is visible usually for human eye.Visible light is showed by color according to the change of properties of wavelength.That is to say, when it when redness changes to purple, wavelength shortens.For example, the wavelength of ruddiness is in the 700-610nm scope, and orange light wavelength is in the 610-590nm scope, the wavelength of gold-tinted is in the 590-570nm scope, the wavelength of green glow is in the 570-500nm scope, and the wavelength of blue light is in the 500-450nm scope, and the wavelength of purple light is in the 450-400nm scope.

When illumination wavelength during greater than the infrared light of 770nm, the surface temperature of the temperature in the apotheca 11 and the food of storage improves.Therefore, food is very fast rotten.For this reason, preferably irradiation unit 20 is designed to light in the visible emitting scope.Because red visible region and infrared light district are not accurately distinguished, so the visible region that defines among the present invention comprises a part infrared light district, and it has the wave-length coverage approaching with the wavelength of red visible region.

Irradiation unit 20 of the present invention is configured such that glow color can change according to the color of the food that stores in the apotheca 11.

By experiment, applicant of the present invention finds, when the glow color of irradiation unit 20 conforms to the color of the food of storage, can keep the fresh and nutritional labeling of food most effectively.For example, red light irradiation is to red food, and green glow shines to pollution-free food.

Based on the above-mentioned fact, this embodiment is constructed so that numerous food classifies according to color and irradiation is changed to the color of the food color according to food.More particularly,, irradiation unit 20 is set to the food irradiation ruddiness that stores, when the color of the food that stores be green, irradiation unit 20 is set to light to the green white combination of food irradiation of storage when the color of the food that stores when be red.

The food that stores in the reservoir vessel 100 can roughly be divided into vegetables and fruit.Vegetables can be further divided into leaf vegetables and the stem dish that leaf and/or stem are used, the root vegetables that root and/or subterranean stem are used, the fruit and vegetable that fruit is used.

In the present invention, more than various vegetables and fruit be divided into redness and green, and irradiation unit is arranged to the light through the food irradiation different colours of classification.

For example, strawberry, tomato, plum etc. belong to red food, and spinach, Chinese cabbage, cabbage etc. then belong to pollution-free food.

Applicant of the present invention has carried out such experiment: food is classified by red and green, use red LED to red food irradiation ruddiness, use green LED and White LED to shine the light of green white combination, and measure the variation of the freshness of the food that stores at the fixed time to pollution-free food.

According to experimental result, to shine visible light without distinction with the use White LED and compare, the variable color of pollution-free food and exsiccation phenomenon significantly reduce, and red food does not almost take place mouldy and the deliquescing phenomenon.

Figure 16 shows according to color with food classification and will be stored in an example of apotheca 11 through the food of classifying respectively.More particularly, the Chinese cabbage and the verdant first apotheca 11a that is arranged in apotheca 11 uppermost position that is stored in that will belong to pollution-free food, the tomato and the strawberry that will belong to red food are stored in the second apotheca 11b that is arranged in medium position, and the cabbage that will belong to pollution-free food is stored in the 3rd apotheca 11c that is arranged in its lowermost position.

The layout of the light-emitting component of irradiation unit of the present invention is described below with reference to Figure 17.

The position of light-emitting component 23 and layout can be ever-changing, can be equably to the food irradiation light that stores but most preferably light-emitting component 23 is arranged to.Figure 17 shows an exemplary arrangement scheme of the light-emitting component 23 that is installed on the irradiation unit on the first apotheca 11a.As shown in Figure 17, red LED 23R, green LED 23G and White LED 23W are positioned at the middle part of top board 12, and this top board is positioned at the top of apotheca 11a.

In detail, the middle part that the top board 12 of LED is installed is circle, and this circle middle part of top board 12 is cut apart by isogonism.Red LED 23R, green LED23G, white, LED23W are positioned at corresponding fan-segmentation zone.

At this moment, because green LED 23G and White LED 23W are driven simultaneously with to the pollution-free food irradiates light, so green LED 23G and White LED 23W are arranged in the corresponding sector region adjacent to each other.

Apotheca 11 also has selecting arrangement 25, and the color that is used for the food that stores respectively corresponding to first to the

3rd apotheca
