Fig. 2 is the cutaway view of the refrigerator 2001 of embodiments of the present invention 2.Light source 213 is arranged on and switches in the chamber 206.The Machine Room 212 of main structural components of taking in the freeze cycle of compressor 216 and condensed device etc. in main body 201, be set at refrigerating chamber 202 above and the back side.

In the past, the Machine Room was positioned at the back side of the refrigerating chamber 203 of the foot that is in main body 201, had therefore reduced the volume of refrigerating chamber 203.But, the back side of the topmost by Machine Room 212 being configured in the refrigerating chamber 202 that is not used effectively in the refrigerator in the past, can increase the volume of refrigerating chamber 203 so can not increase appearance and size with the part of in the past Machine Room as the storeroom utilization.

In addition, in the past for the off-capacity of the refrigerating chamber 203 of the foot that remedies main body 201, the temperature of switching chamber 206 is set at cryogenic temperature, the frequency of using is higher, but the capacity by refrigerating chamber 203 increases, can promote to switch the freezing application in addition of chamber 206, for the user, can carry out the preservation of food with the bigger temperature of scope.As a result, can promote many purposes utilization according to circumstances, can apply flexibly effectively according to the tone of the light of light source 213 and inform the function that temperature is switched to the user as the advantage of switching chamber 206.

(embodiment 3)

Fig. 3 is the cutaway view of the refrigerator 3001 of embodiments of the present invention 3.In refrigerator 3001, be provided with light source 313 on the end face in switching chamber 306, on the inwall 302A of refrigerating chamber 302, be provided with guidance panel 314.

Fig. 4 is arranged on the cutaway view that switches the light source 313 in the chamber 306.Light source 313 has LED327 that the light emitting diode that the illumination wavelength peak value is the ultraviolet light of 387nm (LED) 326, illumination wavelength peak value are the blue light of 468nm, carries LED326,327 and the substrate 328 of control part 328A and cover LED326,327 and the lid 329 of substrate 328.Light source 313 is arranged on the substantial middle portion of switching chamber 306 or the front side of central portion on 306 end faces of switching chamber.LED326,327 is irradiates light downwards.Be located at and cover 329 and switch the liner 330 between the chamber 306 and be located at and cover 329 pawl 331A on every side, the intrusion that 331B prevents water droplet.

In refrigerator 3001, only be set under the situation of 0 ℃ to-7 ℃ ice milk or ice temperature, little cryogenic temperature band that freezes temperature band etc. will switching chamber 306 on the guidance panel 314, control part 328A just makes LED326,327 light a lamp, and in the temperature band higher than them LED326,327 is not lit a lamp.

Normally be used for the storage life of preserving dairy products or meat, fish etc. under the microfreeze state of freezing or non-freezing boundary the temperature band of short reserve from 0 ℃ to-7 ℃ ice milk or ice temperature, little temperature band that freezes.These temperature bands are compared refrigeration energy long preservation reserve, compare with freezing preservation, can easily nurse one's health reserve.For example, the reserve of preserving under these temperature bands can cosily cut with kitchen knife.But in these temperature bands, though that food seems is frozen, in fact the ratio of Jie Binging is carried out the propagation of enzyme reaction and lipoid oxidation reaction, microorganism etc. more than freezing low in inside, and quality reduces gradually.Thus, the fresh food of preserving in these temperature bands need use about 1～2 week.But, because food seems frozen, thus the user think easily food with freezing same can long preservation, the result has excessive the placement chronically and makes the situation of food spoilage.

In order to prevent such situation, in the refrigerator 3001 of embodiment 3, control part 328A does not make light source 313 light a lamp when the temperature of switching chamber 306 is set to the cryogenic temperature band, only light source 313 is lit a lamp during with high temperature band being set at than little freeze, ice temperature, ice milk temperature etc. freezing.Light is radiated at when switching in the chamber 306 at light source 313, makes the user can identification be set at the situation of cryogenic temperature of the short-term preservation usefulness of fresh food class.That is, the irradiation that the user can be by light has or not to come from identification cryogenic temperature visually and cryogenic temperature.Because the long-term placement of the food in the time of can preventing the setting of the cryogenic temperature band that light source 313 is lit a lamp so can prevent the waste of food, can make refrigerator 3001 use easily.

Light source 313 has the LED326 of irradiation ultraviolet radiation and the LED327 of irradiation blue light.For switching the blue slightly blue light of chamber 306 irradiations.By this light, it is impression corresponding to the clean storeroom of the preservations of meat or fish etc. that the user obtains switching chamber 306.

By the ultraviolet ray of LED326 irradiation to swimming in switching chamber 306 or, making the propagation function desactivation of microorganism attached to the gene generation effect of the microorganism on wall or the food.Make compartment interior keep health thus, can delay the variable color of the food that produces because of microorganism or corruption, food surface becomes sticky.Contain the light source 313 of ultraviolet light, the preservation that can improve the conservatory health of food by such setting.

In addition, general ultraviolet ray can promote the class lipid oxidation of food to the long-term irradiation of food, the worry that has the quality of making to reduce, but owing to shine when being preservation to the short-term about 1～2 week of meat or fish, then there is not special problem.In addition, be LED, compare with other lamps by making light source 313, the amount of the light of irradiation a little less than, so the influence of class lipid oxidation is reduced.And then, because LED does not almost have self heating, also be very little so the harmful effect that brings to cooling effectiveness is compared with other lamps.

In addition, because light source 313 is arranged on the substantial middle portion of switching chamber 306 or leans on this side of front than 1/2nd of depth, so reach the front easily from the visible rays of light source 313 irradiations, the quantitative change of the light that spills when the drawer door 308 that switches chamber 306 opens wide is big, so can improve the identification of user to light.

In embodiment 3, in order to make the light diffusion of switching chamber 306, the illuminated portion of the light of light source 313 is arranged on towards the below on the substantial middle part of the end face that switches the chamber, therefore, light can reach on the whole bottom surface of switching the chamber.

And then, spread all over the corner of switching chamber 306 in order to make light, by implementing to have the pears surface processing etc. of polarisation function, light is spread easily to covering a part of 329.And then, can also have the processing of such polarisation effect or Polarizer etc. is installed, it is transparent can also making and cover a part of 329, and light is spread to the part that is difficult to arrive.

In addition, because lid 329 has the protuberance 329C that stretches out from the end face 306A that switches the chamber, so can make the horizontal proliferation of light in case in the case, light reaches the corner easily.

Like this, by light is spread in case, the user is easy identification light more, in addition, if identification is visually penetrated state in the case by the illumination of blueness, then by blue visual effect, can bring switching chamber 206 to the user is the clean spaces that are suitable for preserving meat and fish etc., can improve the grade of refrigerator.

Fig. 8 is the cutaway view of the refrigerator 8001 of embodiments of the present invention 7.In Fig. 8, give identically with reference to label for the part identical with refrigerator shown in Figure 5 5001, omit explanation to it.

In the boundary of depository dish 535, be provided with heat insulating member 518 as the light curtain-shaped cover member with refrigerating chamber 502.The main structural components of the freeze cycle of compressor 516 and condensed device etc. is taken in Machine Room 512.Machine Room 512 is set at quadrate part behind the end face of main body 501.

Fig. 9 is the cutaway view of the light source 513 of present embodiment.Light source 513 has LED527 that the light emitting diode that the illumination wavelength peak value is the ultraviolet light of 387nm (LED) 526, illumination wavelength peak value are the blue light of 468nm, carries LED526,527 substrate 528 and the lid 529 of covered substrate 528, and the user can not look at light source 513 straight.In addition, light source 513 by Screw etc. towards the setting that is fixed of direction down, so that LED526,527 end faces from depository dish 535 shine to the bottom surface.Be located at and cover 529 and switch the liner 530 between the chamber 306 or be located at and cover 529 pawl 531 on every side and prevent that water droplet from invading in the inside.

Heat insulating member 518 improves the thermal insulation of depository dish 535.The temperature of depository dish 535 is expanded as from than-18 ℃ of the cryogenic temperature band of lower temperature under about 40～60 ℃ situation than higher temperatures, also the heat of interval section mobile can be remained less.As a result, the temperature range of depository dish 535 enlarges, and can easily use refrigerator 8001.And then, by heat insulating member 518 depository dish 535 temperature inside changes is reduced, can be reduced in especially subzero to food frost, so the effect of the food quality that can be maintained.In addition, reduce the moving of heat of interval sections by heat insulating member 518, thereby the energy that has reduced waste moves, and can suppress the consumed energy of refrigerator 8001.

In embodiment, only on the guidance panel 514 depository dish 535 is being set under 0 ℃ to-5 ℃ ice milk or ice temperature, little situation of freezing the temperature band, control part 537 is lit a lamp LED526,527, and other temperature band is not lit a lamp.

Because light source 513 has LED526,527, to the light of the blue blueness of the internal irradiation of depository dish 535, this color is obviously different with light source 519.Therefore, the user can pick out the temperature band situation different with the temperature of other parts of refrigerating chamber 502 of depository dish 535 at a glance.In addition, this color can be brought impression with the corresponding clean storeroom of the preservations of meat or fish etc. to the user.

Normally be used for the storage life of preserving dairy products or meat, fish etc. under the microfreeze state of freezing or non-freezing boundary the temperature band of short reserve from 0 ℃ to-7 ℃ ice milk or ice temperature, little temperature band that freezes.These temperature bands can carry out the preservation of the reserve more long-term than refrigeration, compare with freezing preservation, can easily nurse one's health reserve.For example, the reserve of preserving under these temperature bands can cosily cut with kitchen knife.But in these temperature bands, though that food seems is frozen, in fact the ratio of Jie Binging is carried out the propagation of enzyme reaction and lipoid oxidation reaction, microorganism etc. more than freezing low in inside, and quality reduces gradually.Thus, the fresh food of being preserved in these temperature bands need use about 1～2 week.But, because food seems frozen, thus the user think easily food with freezing same can long preservation, the result has excessive the placement chronically and makes the situation of food spoilage.

In order to prevent such situation, in the refrigerator 8001 of embodiment 7, control part 537 does not make light source 513 light a lamp when the temperature of depository dish 535 is set to the cryogenic temperature band, only light source 513 is lit a lamp during with high temperature band being set at than little freeze, ice temperature, ice milk temperature etc. freezing.When light source 513 is radiated at light in the depository dish 535, the situation that the short-term that makes the user can identification be set at the fresh food class is preserved the cryogenic temperature of usefulness.That is, the irradiation that the user can be by light has or not to come from identification cryogenic temperature visually and cryogenic temperature.Because the long-term placement of the food in the time of can preventing the setting of the cryogenic temperature band that light source 513 is lit a lamp so can prevent the waste of food, can make refrigerator 8001 use easily.

By the ultraviolet ray of LED526 irradiation to swimming in depository dish 535 or, making the propagation function desactivation of microorganism attached to the gene generation effect of the microorganism on wall or the food.Thus compartment interior is remained health, can delay the generation that becomes sticky of the variable color of the food by microorganisms or corruption, food surface.Contain the light source 513 of ultraviolet light, the preservation that can improve the conservatory health of food by such setting.

In addition, general ultraviolet ray can promote the class lipid oxidation of food the worry that reduces quality is arranged to the long-term irradiation of food, but if shine during the preservation of the short-term about 1～2 week of meat or fish, does not then have special problem.In addition owing to make light source 513 be LED, compare with other lamps irradiation light amount a little less than, so the influence of class lipid oxidation is reduced.And then, because LED does not almost have self heating, so the harmful effect that brings to cooling effectiveness is compared also very little with other lamps.

Link in the switching with door 507 and to control under the situation of lighting a lamp and turning off the light of light source 513, control part 537 makes the LED526 of the irradiation ultraviolet radiation of light source 513 turn off the light under the situation that door 507 is opened.Be set under the locational situation that the user can't see at light source 513, for example light source 513 also can continue to light a lamp during the switching of drawer type door.Particularly, the light that contains ultraviolet region be can't see for the user, so control part 537 turns off the light LED526 when opening, the LED527 of light of the safety of irradiation visible rays is lit a lamp.When Jiang Men closed, control part 537 was turned off the light LED527, LED526 is lit a lamp.Thus, under the situation that Jiang Men opens, the user can the identification visible light, so can identify the temperature band of storeroom at a glance.When Jiang Men closes, by making the LED526 irradiating ultraviolet light, can access antibacterial effect, and can suppress to consume electric power.Therefore, refrigerator 8001 uses for the user easily, has higher retention for the collecting article of food etc.

The place that is provided with of the light source 513 in the depository dish 535 is not particularly limited, but preferably light source 513 is arranged on when the user opens wide the rotary door 507 of refrigerating chamber, on the position that light source 513 can directly not seen by the user.Open under the situation of revolving door 507 under the state that the women of the average height of certain state stands, light source 513 preferably is configured on the part that can not directly see.Under the situation that other state uses, preferably cooperate the women's of this state average height to set the position that is provided with of light source 513.
