Change control unit 20.
Next, the effect of light irradiation of the explanation based on light emitting device 5.Firstly, illustrating that photosynthesis is reacted.Photosynthesis reaction
When being indicated by chemical formula, indicated as formula below (1).
6CO2+12H2O+688kcal→C6H12O6+6H2O+6O2…(1)
In formula (1), CO2For carbon dioxide, H2O is water, O2For oxygen.688kcal is luminous energy, C6H12O6For glucose.It should
Reaction is divided into light reaction and the unfavorable dark reaction with luminous energy using luminous energy.
Light reaction is that luminous energy is changed into the reaction of chemical energy, and at this stage, carbon dioxide is unutilized, chlorophyll etc.
Water decomposition is hydrogen and oxygen using luminous energy by pigment, accumulates chemical energy by the effect of zymoprotein.On the other hand, dark anti-
Ying Zhong, using the carbon dioxide in the hydrogen and atmosphere generated by light reaction come synthesis of glucose.Vegetable after glucose increase
The storage characteristics of dish improve, and generate vitamin C.
Preferably in 1, using red light, green light and blue light, they are respectively provided with effect.Red light is vegetable
The high wavelength of the absorptivity of the chlorophyll of dish is absorbed on the surface of leaf and is utilized in photosynthesis.Green light is green due to leaf
The absorptivity of element is low, therefore infiltrates into the inside of leaf, and reflection is repeated and is absorbed, is utilized in photosynthesis.Blue light
Carbon dioxide is taken into and sharp as the signal for transmitting the situation of illuminated light to vegetables, and in order to open stomata
With.By above-mentioned effect, photosynthesis shown in formula (1) can efficiently be promoted to react.
The vegetables for being accommodated in the hope irradiation light in the vegetables of lower tank 41 are the leaf vegetables such as spinach, rape and cabbage
Vegetables.On the other hand, it is undesirable to which the vegetables of irradiation light are such as potato.Leaf vegetables vegetables and potato are all placed on lower tank 41
Bottom surface sections 41e on, but potato is lower than the height of leaf vegetables vegetables.
Therefore, by the way that the angle, θ of the emergent light axis Ax of light emitting device 5 is set as 5~85 ° (more preferably 10~45 °),
Can be to wishing vegetables (leaf vegetables vegetables) irradiation light of irradiation light, and avoid to being not intended to the vegetables (potato) of irradiation light to irradiate
Light.
It should be noted that in the region that large-scale PET bottle 201 etc. is stored in the setting of the front of lower tank 41, but
It is the influence that the storage item stored in the region not will receive light irradiation, therefore will not influence the setting of angle, θ.
Light emitting device 5 is preferably configured in than until the bottom surface sections 41e to the bottom surface sections 42e of upper tank 42 of lower tank 41
The center of height position against the top.If light emitting device 5 is configured so that, such as the leaf vegetables vegetables of the lengthwises such as spinach are stood
In the case where acting the back part 41b for the being placed in lower tank 41 and center being placed on the bottom surface sections 41e of lower tank 41 that couches
In the case where, it can be to the leaf vegetables vegetables irradiation light of the lengthwise.
Here, it is provided with the upper tank 42 as small vegetables box in the top of the lower tank 41 as big vegetables box, but
Big vegetables box can be set in the top of small vegetables box upside down.It in this case, is not in the small of small vegetables box storage
Vegetables roll into big vegetables box and it is not perceptible during occur it is corrupt.Moreover, big vegetables box is as small vegetables box
Lid functions, therefore can inhibit the drying for not being finished vegetables also.In such manner, it is possible to globality improve and store in vegetable compartment 15
The quality of vegetables.
Next, the light irradiation control of the light emitting device 5 in the refrigerator 1 that explanation is constituted as previously discussed.Firstly, illustrating vegetable
The concept of the activation of the function of dish.Biology has day-night rhythm more, i.e., is grown, plant as normal condition round the clock using existing
It is unexceptional.Though be save in vegetables also grow, it is therefore desirable to provide with harvesting before in the same manner as irradiation light time-bands and
The time tape alternation of irradiation light does not arrive i.e. in the presence of environment round the clock.
Therefore, light emitting device 5 makes lighting and extinguishing with certain rhythm repeatedly for LED.When the lighting time of LED and extinguishing
Between be respectively 5 hours or more, preferably 5~15 hours.This is because if lighting and extinguishing repeatedly with too short circulation,
It is dimmed before the biological synthetic functional activation based on light occurs, do not change compared with not irradiation light.
The case where irradiating blue light to plant is as the signal started to the irradiation of plant notice light, therefore plant is (herein
For vegetables) open stomata and the carbon dioxide needed for being taken into biosynthesis in air.While irradiating blue light, irradiation promotees
Into the vitamin C etc. of the chlorophyll activation and the generation of the glucose based on biological synthetic functional and accompanying this of vegetables
The red light and green light of synthesis.
It should be noted that blue light it is weaker than red light and green light light quantity it is more effective.Therefore, the light quantity of blue light is excellent
The 1/4 of each light quantity of red light and green light is selected as hereinafter, more preferably 1/5~1/10.It should be noted that making vegetables
After stomata is opened, it is desirable to extinguish blue light.After light irradiation continue for certain time in this way, the LED of light emitting device 5 is put out
It goes out.
Based on above point, illustrate the movement (light irradiation control) of light emitting device 5.Figure 10 indicates light emitting device 5
The flow chart of the process of movement.After the power supply of refrigerator 1 is switched on, the operation of operation panel 21 is controlled according to user
Portion 20 starts the light mutually fitted with the day-night rhythm of vegetables irradiation control (step S1).First, it is determined that whether being currently that should carry out light
The time-bands (band in the daytime) (step S2) of irradiation.
It is that the judgement of band or night band in the daytime uses the 24 hours timers progress for being set to control unit 20.For example, by 6
Point~18 point are redefined for band in the daytime, will be redefined for night band in addition to this.In the daytime the timing of band and the night band can
According to seasonal variations.For example, can be set as, in the period of the Summer Solstice, band longest in the daytime, in the period of Winter Solstice, band is most in the daytime
It is short.Moreover, here, band will be combined and be set as 24 hours with night band in the daytime, but its length can suitably change.
In step s 2, in the case where being judged as currently is band in the daytime, control unit 20 opens the light irradiation of day mode.
That is, starting simultaneously at the irradiation of the red light based on LED51a, 51b, the irradiation of green light based on LED52a, 52b and being based on
The irradiation (step S3) of the blue light of LED53a, 53b.As described above, red light and green light are suitable for the function of vegetables
The light of activation, blue light are the light as the triggering for the stomata for opening vegetables.Also, control unit 20 starts for example based on timer
Day mode time measure (step S4).
The stomata that the irradiation of blue light based on LED53a, 53b the carries out vegetables time required until opening, such as 10 points
More than clock, after the time, LED53a, 53b are extinguished into (step S5).Then, the warp from day mode is obtained
Time (step S6) is crossed, when reaching preset day mode upper limit time by the time (step S7), is changed into night
Mode and by LED51a, 51b, 52a, 52b extinguish (step S8).Whole LED51a~53b extinguishes as a result, and night mode is opened
Begin.
Control unit 20 starts the time measurement of such as night mode based on timer along with the beginning of night mode
(step S9).Then, it obtains and passes through time (step S10) from night mode, preset when reaching by the time
