Technical field

The present invention relates to a kind of refrigerator, and relate more specifically under fresher state, to preserve the refrigerator of vegetables and fruit or meat and fish.

Background technology

In general, refrigerator comprises refrigerating chamber and refrigerating chamber.Apotheca is located at the specific location in the refrigerating chamber separately, so that come more preserving vegetables and fruit (below will be referred to as " vegetables ") or meat and fish under the fresh state by optimizing humidity.Therefore, the storeroom in the refrigerating chamber can be an example of food storage container.

Now with reference to Fig. 1 the conventional refrigerator with food storage container is described.

At the conventional refrigerator shown in Fig. 1 is at the refrigerator disclosed in the Japanese Patent Laid communique No.9-28363.As shown in the figure, food storage container 2 is located in the overhead refrigerator, and wherein refrigerating chamber is arranged on top and refrigerating chamber is located at the bottom.

For example many factors of temperature, humidity, environmental gas, microorganism, light etc. all can influence the freshness of vegetables.Because vegetables breathe continuously and transpiration, so necessary inhibition breathing and transpiration are so that keep the fresh of vegetables.Most of vegetables--except some vegetables that can go wrong at low temperatures--suppress respiration at low temperatures, and suppress transpiration under high humility.

For this reason, general domestic refrigerator is provided with the separate space of food storage container to separate as refrigerating chamber that is used for depositing specially vegetables, so that for a long time vegetables are deposited under the fresh state.By the moisture that from vegetables, evaporates, make the food storage container remain under enough low temperature and the high as far as possible humidity.Therefore, vegetables are left in the food storage container for a long time in fresh state.

Simultaneously, studying by making the method that (influence factor that another is relevant with the vegetables freshness) keeps the vegetables freshness of using up.

Stronger light has the adverse effect that promotes that vegetable colour changes and evaporates relatively, and more weak light has the effect of improvement to keeping of vegetables freshness relatively.Also have, the low light level has suppressed greenery has the chlorophyll of stem vegetables to decompose, and has the effect that maintains Vitamin C.

Refrigerator 1 shown in Figure 1 is provided with irradiation apparatus 6, and this equipment is irradiated into food storage container 2 with the low light level, has the chlorophyll of stem vegetables to decompose to prevent greenery, and therefore prevents that greenery from having the quality deterioration of stem vegetables.Above drawer type food storage container 2, be provided with irradiation light 8.When drawer type food storage container 2 was opened, irradiation light 8 was luminous so that the user can be easy to see the food in the storeroom 4.When drawer type storage container 2 was closed, the light-emitting device 6 irradiation low light levels had the quality deterioration of stem vegetables to prevent greenery.

Japanese Patent Laid communique No.11-159953 has disclosed a kind of refrigerator that is provided with irradiation apparatus, and described irradiation unit is the light emitting diode (LED) that is transmitted in the light in the visible region.Therefore, reduced heating, prevented that the temperature in the storeroom from raising, and compared with other irradiation apparatus and to have improved illumination efficiency from irradiation apparatus.

But the above-mentioned conventional refrigerator with food storage container has following problem.

Can selectively make up the versicolor light of launching from the LED of three kinds of colors (red, blue, green), but can not determine that in red-light LED, blue-ray LED and the green light LED which is effective for which kind of food.Therefore, this irradiation unit is for the freshness that keeps stored food and prevent that chlorophyll from decomposing speech and not having effect.

Though the food storage container is separated into several storerooms, but,, the food storage container do not have any effect so being separated into several storerooms because the user classifies to food and will put into the reference of each storeroom institute foundation and unclear separately through the food of classification.

Also have, in traditional irradiation apparatus, be provided with the device of the color that is used to select the light launched from three-color LED, but this selecting arrangement since lack which kind of glow color for the definite information of which kind of food and and impracticable.Though find that by test which kind of glow color is the most effective for which kind of food, the user is difficult to remember one by one these information to select glow color, and perhaps user's this information of retrieval before selecting glow color bothers very much.

In addition, for food, the relation of itself and glow color does not determine through overtesting that the user can not determine which kind of glow color is effectively for food, and can not be sure of whether user-selected glow color is effective for food.Therefore, the user can distrust this irradiation apparatus.

For food is remained in the fresher state for a long time, set the humidity in the refrigerating chamber high as far as possible.But humidity is high more, then has more various bacterium and breeds in refrigerating chamber.Also have, the air of refrigerating chamber can be full of bad taste.

Simultaneously, the control module (not shown) can be controlled irradiation apparatus 30, according to the color that is housed in the food in

storeroom

20,22 and 24 light of different colours is irradiated into

storeroom

20,22 and 24.

By test, applicant of the present invention finds, when the color of the glow color of irradiation apparatus and the food of being preserved is complementary, can keep the freshness and the nutrient of food most effectively.For example, red light irradiation is to red food, and green glow shines green food.

According to the above-mentioned fact, the structure of present embodiment makes according to the color multiple food of classifying, and exposes to the color of the light of food according to the color change of food.In particular, when the color of the food of being preserved is redness, irradiation apparatus 30 is set at red light irradiation to the food of being preserved, and the color of working as the food of being preserved is when being green, and irradiation apparatus 30 is set at green-Bai combined light is shone the food of being preserved.Especially, the present inventor finds by test, shines green-Bai combined light rather than shines pure green glow to green food, can more effectively keep the freshness of food and prevent that chlorophyll concentration from reducing.

The food that is housed in the food storage container 12 can mainly be divided into vegetables and fruit.The fruit type vegetable that vegetables can be further divided into the leaf bar class vegetables of using its leaf and/or bar, use its root and/or rhizomatous roots vegetable and use its fruit.In the present invention, above-mentioned various vegetables and fruit are divided into redness and green, and irradiation apparatus is made as to minute light of group food irradiation different colours.For example, strawberry, tomato, plum etc. belong to red food, and spinach, Chinese cabbage, cabbage etc. belong to green food.

Applicant of the present invention tests, food is divided into redness and green, use red-light LED to give red food irradiation ruddiness, use green light LED and white light LEDs to shine combined light green and white, and the freshness of the food that measurement is preserved at the fixed time changes to green food.

According to result of the test, compare with the situation of using white light LEDs irradiation visible light without distinction, in the green food fade and dry-out phenomenon obviously reduces, do not produce mouldy in the red food substantially and phenomenon deliquescing.
