In Fig. 1, in the inside of refrigerator 1000, under normal circumstances, carried towards each storeroom via cooling air duct 1010 by air transport device 1003 by air in the cooled case of cooling chamber 1002.And then, form each storeroom is carried out to the cooled air that returns via the circulation wind path that returns to wind path 1020 and again return cooling chamber 1002.
In vegetable compartment 400, refrigerating chamber 100 is carried out to cooled air (refrigerating chamber returns to air) and return to wind path 110 via refrigerating chamber and be transported to the vegetable compartment that is disposed at vegetable compartment end face and return to wind path 410.Now, the design temperature of refrigerating chamber 100 (for example 1～3 ℃) is for example, than vegetable compartment 400 (5～7 ℃) lower.And, refrigerating chamber returns to wind path 110 through the lower switching chamber 200 of excess temperature, refrigerating chamber 300 and is cooled, therefore, flow into vegetable compartment while returning to wind path 410 when refrigerating chamber returns to air, vegetable compartment 400 and vegetable compartment container 401 are cooled indirectly by returning to the cold emission of wind path 410 from vegetable compartment.
Then, refrigerating chamber returns to air and flows into vegetable compartment from vegetable compartment return port 411 and returns to the vegetable compartment of wind path 410 and return to air and mix (and not shown, but return in wind path 410 in vegetable compartment, vegetable compartment return port 411 is configured in to be compared vegetable compartment and returns to wind path 410 and refrigerating chamber and return to the position that point that wind path 100 converges is swum on the lower), be discharged to and return to wind path 1020 from refrigerating chamber/vegetable compartment return port 412, and carried towards cooler 1002.
In common running, each storeroom is carried out to cooled to return to air dehumidified in cooling by cooler 1002.Thereby although produce the switching from the door of the moisture transpiration of food, refrigerator 100 when picking and placeing food because putting into food, the temperature inside the box temporarily increases, dehumidified and be finally reduced to the degree of 20～30%RH gradually.When by the case of the food of the keeping of normal temperature state or placement moves under this low wet environment, can produce the moisture transpiration from food.Particularly, the transpiration of vegetables is carried out in the time that the water vapour pressure (degree of saturation vapor pressure × 0.98) of vegetable surface is higher than the water vapour pressure of surrounding environment, and transpiration rate and water vapour pressure are poor proportional.Therefore, when by the case of the vegetables of the keeping of normal temperature state or placement move under low temperature environment, until ambient water steam pressure rises to the level equal with saturation vapor pressure, continue to occur transpiration, freshness reduces.
Therefore, as shown in Figure 2, vegetable compartment container 401 is separated into the first storage container 1, the second storage container 2, the 3rd storage container 3, as the first storage container 1, utilize the first storage container cap 1a to form air-tight state or semi-hermetic state, for the second storage container 2, utilization can before and after the 3rd storage container 3 that slides stop up a part for its peristomes and improve leak tightness, thus, even if in the case of the identical vegetables of keeping or in the situation that beginning to cool down from uniform temp, also can form different humidity environments by the difference of leak tightness.
Fig. 4 is an example of the measured data of the actual weight slip (=water transpiration weight/initial stage weight) that is kept at the vegetables loads (water transpiration weight) in vegetable compartment container 401, (a) being the data that are kept at the vegetables of (humidity is more than 90%RH) in the first storage container 1, is (b) data that remain on the vegetables of (humidity 20～30%RH) in the 3rd storage container 3.In addition, in Fig. 4, as vegetables load, spinach and radish are shown.In more detail, 11a to 11c is the weight slip of the spinach (11a is that 100g, 11b are that 500g, 11c are 1000g) that varies in weight at the initial stage.The 12nd, be cut into the weight slip of 1/2 radish.The 13rd, be cut into the weight slip of 1/4 Chinese cabbage.
From Fig. 4 (a) and Fig. 4 (b): for the transpiration rate of vegetables, present maximum transpiration rates as the spinach of leaf vegetables, like this, the transpiration rate of vegetables is according to the kind of vegetables and difference, and, even if identical vegetables, weight is fewer more with respect to the less transpiration rate of volume ratio of storage container.And known: as (Fig. 4 (a)) in the situation that is stored in the first storage container 1, compare with the situation (Fig. 4 (b)) that is stored in the 3rd storage container 3, transpiration rate is suppressed to 1/5～1/10 degree, and freshness is maintained.This is because of effect following former thereby that obtain: compared with the 3rd storage container 3, the first storage container 1 is high humility, in addition, in the first storage container 1, form roughly air-tight state, therefore, compare with the 3rd storage container 3 of opened upper end, the temperature change in storage container is little, and the breathing of vegetables is suppressed.
Like this, the vegetable compartment container 401 being indirectly cooled by returning to the cold emission of wind path 410 from vegetable compartment is separated into multiple storage containers by the related refrigerator 1000 of present embodiment 1.In addition, form different humidity spaces by the difference of the leak tightness of the realizations such as the lid by storage container, storage container configuration each other, one of them is formed as to roughly closed container.Thereby in closed container roughly, high humility is maintained, by airtight, temperature change diminishes, and the breathing of vegetables is suppressed, and therefore, in the case of the many vegetables of the transpiration rates such as keeping leaf vegetables, can suppress transpiration rate and maintains freshness.
On the other hand, for the vegetables that do not need high humility, for example under high humidity environment, exist the possibility of envenomation fruit, dewfall water be bonded at lip-deep mud and contact and become the root vegetableses such as antihygienic potato, burdock, be kept at leak tightness low and become better in the storage container of low humidity, therefore, can be in the different multiple storage containers of humidity environment take care of with the optimum humidity environment adapting with food, and, owing to taking care of for the transpiration characteristic of vegetables, therefore can obtain the effect of the raising that can realize arrangement property.
As mentioned above, being formed as in the first storage container 1 of air-tight state or semi-hermetic state by the first storage container cap 1a, high humility is maintained, and the transpiration of vegetables is suppressed.But, in the storage container of the first storage container 1, be particularly cooled by returning to the cold emission of wind path 410 from vegetable compartment.Thereby, there is the possibility in the back side of the first minimum storage container cap 1a of temperature (i.e. the first storage container 1 with the opposed wall of cooling air duct) generation dewfall.And then, fall and vegetables load 402 is rotted or because of the possibility of the problems such as the dew that is detained is mouldy when there is when dewfall, exist to occur dew.
Therefore,, in present embodiment 1, by utilizing the lid aperture portion 7 shown in Fig. 2 and Fig. 3 to carry out exhaust to highly humid air, can suppress or avoid dewfall.Now, as shown in Figure 4, according to the kind of vegetables loads, amount and transpiration rate difference, therefore, need to utilize and cover aperture portion opening and closing shutter 8 and control capacity, i.e. humidity in the first storage container 1.
Fig. 5 is the humidity environment control flow chart of the refrigerator vegetable chamber (the first storage container 1) in embodiment 1 of the present utility model.In addition, Fig. 5 is the figure that the Control the content of the humidity environment control device 10 shown in Fig. 3 is shown, is all the step that humidity environment control device 10 carries out except the step S1 that user carries out.
In the time that user opens and closes the first storage container cap 1a (step S1), in step S2, utilize air themperature checkout gear 4 to detect the air themperature T in the first storage container 1 a.And, utilize air humidity detection device 5 to detect the air humidity H in the first storage container 1 a.In addition, with vegetables load 402 put into and/or take out irrelevant, in the time of the first storage container cap 1a switching, just carry out step S2.
In step S3, use detected air themperature T awith air humidity H acalculate the dew-point temperature T in the first storage container 1 dew.Secondly,, in step S4, utilize the cap surface temperature T of covering temperature-detecting device 6 and detect the inner surface (lower surface) of the first storage container cap 1a sur, and in step S5 to cap surface temperature T surwith dew-point temperature T dewmagnitude relationship compare.Now, when cap surface temperature T surat dew-point temperature T dewin following situation, exist in the inner surface of the first storage container cap 1a dewfall or the possibility of dewfall at once.Therefore, when being judged to be cap surface temperature T surat dew-point temperature T dewin following situation, with air humidity H avalue irrelevant, advance to step S8 and send the control signal that makes to cover aperture portion opening and closing shutter 8 and open one-level towards opening and closing shutter drive unit 9.
On the other hand, when be judged to be cap surface temperature T in step S5 surbe greater than dew-point temperature T dewsituation under, advance to step S6, to air humidity H awith predefined air humidity control range upper limit humidity H aHmagnitude relationship compare.Now, when being judged to be air humidity H abe greater than air humidity control range upper limit humidity H aHsituation under, be judged as in the possibility of the inner surface dewfall of the first storage container cap 1a high, and, even if control vegetables load 402 transpiration rate aspect be also too high humidity.Thereby, advance to step S8 and send the control signal that makes to cover aperture portion opening and closing shutter 8 and open one-level towards opening and closing shutter drive unit 9.
When be judged to be air humidity H in step S6 aat air humidity control range upper limit humidity H aHin following situation, advance to step S7, to air humidity H awith predefined air humidity control range lower limit humidity H aLmagnitude relationship compare.Now, when being judged to be air humidity H abe less than air humidity control range lower limit humidity H aLsituation under, be judged as humidity deficit to suppress the transpiration rate of vegetables load 402 and low in the possibility of the inner surface dewfall of the first storage container cap 1a.Thereby, advance to step S9, send the control signal that makes to cover aperture portion opening and closing shutter 8 and close one-level towards opening and closing shutter drive unit 9.
When be judged to be air humidity H in step S7 aat air humidity control range lower limit humidity H aLin above situation, be judged as air humidity H abe contained in air humidity control range upper limit humidity H aHwith air humidity control range lower limit humidity H aLbetween, not in the inner surface dewfall of the first storage container cap 1a and can suppress the best humidity range of the transpiration rate of vegetables load 402.Thereby, return to step S2, repeating step S2～S7.
In the situation that making to cover aperture portion opening and closing shutter 8 open and close in step S8 or S9, when in step S10 by percent opening elapsed time t after changing pastafter replacement, instrumentation elapsed time t in step S11 past(calculating the elapsed time after resetting).
Secondly, in step S12, to elapsed time t pastwith predefined percent opening stand-by time t after changing waitmagnitude relationship compare.Now, when being judged to be elapsed time t pastat percent opening stand-by time t after changing waitin above situation, be judged as for the switching by lid aperture portion opening and closing shutter 8 and passed through the sufficient time the interior generation humidity of the first storage container 1 changes, return to step S2, repeating step S2～S12.When be judged to be elapsed time t in step S12 pastbe less than percent opening stand-by time t after changing waitsituation under, be judged as the elapsed time of covering after aperture portion opening and closing shutter 8 opens and closes insufficient, return to step S11, repeating step S11～S12.
Fig. 6 is an example of humiture measured data while utilizing the humidity environment control flow chart shown in Fig. 5 to control, refrigerator vegetable chamber (the first storage container 1), (a) being the time series data of temperature, is (b) time series data of humidity.
In Fig. 6, the 14th, the air themperature (T of the first storage container 1 being detected by air themperature checkout gear 4 a).The 15th, the air humidity (H of the first storage container 1 being detected by air humidity detection device 5 a).The 16th, the dew-point temperature (T of the first storage container 1 calculating according to the air themperature of the first storage container 1 and air humidity dew).The 17th, the cap surface temperature (T of the inner surface (lower surface) of the first storage container cap 1a being detected by lid temperature-detecting device 6 sur).The 18th, as not dewfall and can suppress the best humidity range of transpiration rate of vegetables load 402 and predefined air humidity control range of the inner surface at the first storage container cap 1a, 18a is air humidity control range upper limit humidity (H aH), 18b is air humidity control range lower limit humidity (H aL).Be set as H herein aH=95%RH, H aL=85%RH.The 19th, sufficient time as the switching for by cover aperture portion opening and closing shutter 8 and the interior generation humidity of the first storage container 1 changes and predefined percent opening stand-by time (t after changing wait).Moment when lid is opened and closed is made as t 0, by every process t waittime moment be set as t 1, t 2..., t 8.The 20th, cover aperture portion opening and closing shutter 8 during open mode, the 21st, lid aperture portion opening and closing shutter 8 is during closed condition, and both sides' least unit is percent opening stand-by time 19 (t after changing wait).
According to the humidity environment control flow chart shown in Fig. 5, the humiture measured data of Fig. 6 is described.
When at moment t 0when the first storage container cap 1a opens and closes (step S1), air themperature checkout gear 4 detects the air themperature 14 (T in the first storage container 1 a), air humidity detection device 5 detects the air humidity 15 (H in the first storage container 1 a) (step S2).And then, use air themperature 14 (T a) and air humidity 15 (H a) calculate the dew-point temperature 16 (T in the first storage container 1 dew) (step S3).And, utilize the cap surface temperature 17 (T that cover temperature-detecting device 6 and detect the inner surface (lower surface) of the first storage container cap 1a sur) (step S4, whenever arriving each moment t 1, t 2..., t 8time just implement above-mentioned action).Although cap surface temperature 17 (T sur) be greater than dew-point temperature 16 (T dew) (step S5's is no), but due to air humidity 15 (H a) be greater than air humidity control range upper limit humidity 18a (H aH) (step S6 is), therefore make to cover aperture portion opening and closing shutter 8 and open one-level (step S8), by percent opening stand-by time (t after changing past) reset (step S10) afterwards, start elapsed time (t past) instrumentation (step S11).
At moment t 1, air humidity 15 (H a) there is the tendency that declines, but cap surface temperature 17 (T sur) be greater than dew-point temperature 16 (T dew), air humidity 15 (H a) be greater than air humidity control range upper limit humidity 18a (H aH) situation do not change, therefore repeat and moment t 0time same action.
At moment t 2, air humidity 15 (H a) also there is the tendency that declines, but cap surface temperature 17 (T sur) become dew-point temperature 16 (T dew) following (step S5 is), therefore make to cover aperture portion opening and closing shutter 8 and further open one-level (step S8), then standby is until elapsed time (t past) arrival percent opening stand-by time (t after changing wait) moment t 3(step S10～S12).
At moment t 3, cap surface temperature 17 (T sur) be greater than dew-point temperature 16 (T dew) (step S5's is no), air humidity 15 (H a) at air humidity control range upper limit humidity 18a (H aH) following (step S6's is no), and be further less than air humidity control range lower limit humidity 18b (H aL) (step S7 is), therefore make to cover aperture portion opening and closing shutter 8 and close one-level (step S9), then carry out standby equally until moment t 4(step S10～S12).
At moment t 4, t 5, cap surface temperature 17 (T sur) be greater than dew-point temperature 16 (T dew) (step S5's is no), air humidity 15 (H a) at moment t 4be greater than air humidity control range upper limit humidity 18a (H aH) (step S6 is).Therefore, make to cover aperture portion opening and closing shutter 8 and open one-level (step S8), at moment t 5be less than air humidity control range lower limit humidity 18b (H aL) (step S7 is), therefore make to cover aperture portion opening and closing shutter 8 and close one-level (step S9).
At moment t 6, cap surface temperature 17 (T sur) be greater than dew-point temperature 16 (T dew) (step S5's is no), air humidity 15 (H a) at air humidity control range upper limit humidity 18a (H aH) following (step S6's is no), and at air humidity control range lower limit humidity 18b (H aL) above (step S7's is no).Thereby, owing to being contained in air humidity control range 18, therefore do not change the percent opening that covers aperture portion opening and closing shutter 8, return air themperature 14 (T a) and air humidity 15 (H a) detection (step S2).
At moment t 6～t 7, moment t 6the magnitude relationship of humiture constant, therefore maintain that to cover the percent opening of aperture portion opening and closing shutter 8 constant.
At moment t 7although, air humidity 15 (H a) be contained in air humidity control range 18, but cap surface temperature 17 (T sur) become dew-point temperature 16 (T dew) following (step S5 is), therefore make to cover aperture portion opening and closing shutter 8 and open one-level (step S8).
After this standby is until moment t 8(step S10～S12).
To sum up, in the refrigerator 1000 forming as present embodiment 1, arranging and covering aperture portion 7 as the first storage container 1 of closed container roughly, detect the air themperature in the first storage container 1, the inner surface temperature of air humidity and the first storage container cap 1a, to make inner surface temperature higher than the dew-point temperature calculating according to air themperature and air humidity, and the mode that air humidity enters the high humility scope of regulation opens and closes lid aperture portion opening and closing shutter 8, and to the capacity from lid aperture portion 7 the air humidity in the first storage container 1 control, thus, can obtain following effect: do not rely on according to the kind of the vegetables load in inside keeping, measure and different transpiration rates, not in the inner surface dewfall of the first storage container cap 1a, and can suppress the effect of the transpiration of vegetables load.Particularly in the situation that inner surface temperature is below dew-point temperature, do not rely on air humidity, preferentially by open cover aperture portion opening and closing shutter 8 make dew-point temperature decline, therefore the inner surface dewfall at the first storage container cap 1a can be avoided reliably, the problem such as mouldy that vegetables are loaded the impact that causes, caused because of the dew being detained that falls because of dew can be prevented.
In addition, in Fig. 2, vegetable compartment container 401 is separated into the first storage container 1, the second storage container 2 and the 3rd storage container 3, utilize the first storage container cap 1a that the first storage container 1 is formed as to roughly air-tight state, utilization can before and after slide the 3rd storage container 3 stop up the second storage container 2 peristome a part and improve leak tightness, form thus the storage container of three temperature bands.For example, but the structure of the related vegetable compartment container 401 of present embodiment 1 is not limited thereto, and also can reduce the separation quantity (being the separation quantity of humidity band) of vegetable compartment 400.For example also can utilize and form roughly the first storage container 1 of confined space and the second blocked storage container 2 of a part for peristome and form vegetable compartment container 401.Now, as long as the lids that can slide in the peristome setting of the second storage container 2 etc. stop up a part for the peristome of the second storage container.And, for example, also can utilize to form roughly the first storage container 1 and the 3rd storage container 3 of confined space and form vegetable compartment container 401.And, for example, because the temperature band of the 3rd storage container 3 is interior identical with vegetable compartment 400, therefore, can take care of the cavity of food if the space in vegetable compartment 400 beyond vegetable compartment container 401 exists, also can will in vegetable compartment 400, be separated into multiple humidity bands even if only utilize the first storage container 1 to form vegetable compartment container 401.When in the situation of separation quantity that reduces like this vegetable compartment container 401 (being in other words vegetable compartment 400), it is large that the volume of each storage container becomes, and therefore can entirely receive the vegetables that Chinese cabbage, root-mustard etc. are larger.
And, can certainly increase the separation quantity (being the separation quantity of temperature band) of vegetable compartment 400, increase the temperature band in vegetable compartment 400.When in the situation of separation quantity that increases like this vegetable compartment container 401 (being in other words vegetable compartment 400), even if can suppress its transpiration for diced vegetables industry as shown in Figure 4, therefore can obtain vegetables can being cut into small pieces and take care of and can realize the effect of raising of arrangement property according to kind.
And, in Fig. 2, fore-and-aft direction, above-below direction the first storage container 1, the second storage container 2 and the 3rd storage container 3 as closed container are roughly being separated at left and right directions, but decoupled direction there is no the special restriction, even if also can obtain same effect.Particularly in the related refrigerator 100 of present embodiment 1, due to the structure (owing to being formed with cooling air duct above vegetable compartment container 401) that is formed as the first storage container cap 1a of the top part that forms vegetable compartment container 401 and is cooled, therefore, if separate and the first storage container 1 be configured in to orlop at above-below direction, because the impact of returning to the temperature change that the cold emission of wind path 410 causes from vegetable compartment diminishes, the breathing of vegetables is suppressed, and therefore can obtain further suppressing transpiration rate and the effect that maintains freshness.
And, in Fig. 2 and Fig. 3, be formed as following structure: the rectangular opening that lid aperture portion 7 is formed as to multiple shape of slit, utilize track to guide the lid aperture portion opening and closing shutter 8 that is arranged at each slit, and utilize rotation motor to carry out on-off action, but above-mentioned shape and structure there is no the special restriction.For example, also can by lid aperture portion 7 be formed as a larger hole, or be clathrate, word shape arrange circular port.And, for example, also lid aperture portion opening and closing shutter 8 can be formed as to slidingtype, rotary etc. and carry out on-off action.As long as can discharge the air of the first storage container 1 inside from lid aperture portion 7, and utilize and cover aperture portion opening and closing shutter 8 and adjust discharge rate, just can obtain same effect.
And, in Fig. 2, Fig. 3 and Fig. 5, based on the air themperature T of the first detected storage container 1 of air themperature checkout gear 4 a, detected the first storage container 1 of air humidity detection device 5 air humidity H a, use air themperature T awith air humidity H adew-point temperature T in the first storage container 1 calculating dew, detected the first storage container cap 1a of lid temperature-detecting device 6 the cap surface temperature T of inner surface (lower surface) sur, humidity environment control device 10 covers the on-off action of aperture portion opening and closing shutter 8, regulates the Bas Discharged amount from lid aperture portion 7.But, as shown in the measured data of Fig. 6, air humidity 14 (T a) and cap surface temperature 17 (T sur) except the moment t of the first storage container cap 1a after just having opened and closed 0～t 1outside be equal temperature, therefore, also can delete either party's temperature-detecting device, and use the opposing party temperature-detecting device detected value replace.And checkout gear can be also only air humidity detection device 5, by air humidity H aair humidity control range upper limit humidity H aHset lowlyer, by air humidity control range lower limit humidity H aLset highlyer, control with narrower air humidity control range.Although accuracy of detection reduces slightly owing to having cut down checkout gear, can realize cost degradation, and can be by the air humidity H of the first storage container 1 abe controlled at the inner surface of the first storage container cap 1a and do not produce dewfall and can suppress the humidity range of the transpiration of vegetables loads, therefore can obtain roughly equal effect.
And, in Fig. 5, for the closing motion of the lid aperture portion opening and closing shutter 8 in opening action, the step S9 of the lid aperture portion opening and closing shutter 8 in step S8, send and drive signals towards opening and closing shutter drive unit 9 in the mode that opens and closes respectively one-level at every turn, but also can not be fixed on one-level.For example,, when being judged to be cap surface temperature T surat dew-point temperature T dewin following situation (step S5 is), make to cover aperture portion opening and closing shutter 8 and open two-stage above or make it standard-sized sheet, as air humidity H abe greater than air humidity control range upper limit humidity H aHtime (step S6 is) and be less than air humidity control range lower limit humidity H aLtime (step S7 is), air humidity H awith the larger progression that more increases the on-off action that covers aperture portion opening and closing shutter 8 of difference of air humidity control range, thus, the air humidity H of the first storage container 1 acontrol accuracy improve, can obtain preventing more reliably the inner surface dewfall at the first storage container cap 1a, and can suppress the effect of the transpiration of vegetables loads.
And the structure of the vegetable compartment container 401 to vegetable compartment 400 inside in Fig. 2 and Fig. 3 is illustrated, but also said structure can be applied to the inside of refrigerating chamber 100 other storerooms such as grade, for carrying out the keeping of food.In refrigerating chamber 100, if fresh food, home cooking etc. are taken care of in the first storage container 1, without expending the labour who utilizes preservative film to pack, put into food box etc., can suppress moisture transpiration and maintain freshness, good to eat degree, and, even if in refrigerating chamber 300, also can be in the inner dewfall that suppresses of the first storage container 1, therefore can obtain can be with the effect that mode in the surperficial frosting of frozen food is not carried out keeping.
And, in Fig. 1 and Fig. 3, be arranged on the top of vegetable compartment container 401 for vegetable compartment container 401 being carried out to indirect cooling cooling air duct, but the forming part of cooling air duct is arbitrarily.For example also can cooling air duct be set so that the wall of vegetable compartment container 401 sides is carried out to cooling mode.Now, lid temperature-detecting device 6, lid aperture portion 7, lid aperture portion opening and closing shutter 8 and opening and closing shutter drive unit 9 also can be arranged at vegetable compartment container 401 with the opposed wall of cooling air duct.And, for example, can certainly cooling air duct be set so that multiple walls of vegetable compartment container 401 are carried out to cooling mode.In this case, can arrange and cover temperature-detecting device 6, lid aperture portion 7, lid aperture portion opening and closing shutter 8 and opening and closing shutter drive unit 9 and implement the utility model by least one in the wall being cooled.
[embodiment 2]
Fig. 7 is the stereogram that is arranged at the vegetable compartment container in refrigerator in embodiment 2 of the present utility model.And Fig. 8 is the Sketch figure of the refrigerator vegetable chamber in embodiment 2 of the present utility model, and it is the cutaway view of observing from the side the first storage container 1.
In Fig. 7 and Fig. 8, for the position identical with embodiment 1, description thereof is omitted, water adsorption device 22 is the parts that airborne moisture carried out to moisture absorption or moisture releasing, is arranged at the inner surface (lower surface) of the first storage container cap 1a in the mode of blank cap aperture portion 7.
Water adsorption device 22 uses to be had the coating such as nonwoven or Porous base material of aeration, surface treatment or is containing the parts that are soaked with adsorbent.Herein, so-called sorbing material refers to that such as silica gel or active carbon etc. have the material of more characterization of adsorption for highly humid air.As supporting in the adsorbent of water adsorption device 22, be contemplated to be particularly for its adsorbance of highly humid air more than 80%RH sharply increase, i.e. the pore aperture more consistent material within the specific limits of adsorbent.
Fig. 9 is supporting in the schematic diagram of the absorption isotherm of the various adsorbents of water adsorption device in embodiment 2 of the present utility model.In addition, in Fig. 9, transverse axis illustrates that, to ethereal relative humidity, the longitudinal axis illustrates the equilibrium adsorption capacity of moisture.And, in Fig. 9,23 illustrate the absorption isotherm of common silica gel, 24 illustrate the absorption isotherm of common active carbon, and 25 illustrate absorption isotherm pore, carried out the adsorbent of strengthening as the absorption to high humidity of porous silica material of the degree that is provided with multiple 10～20nm (nanometer).
For common silica gel, as shown in absorption isotherm 23, exist the relative humidity of air at the first relative humidity 26 (φ 1) equilibrium adsorption capacity of moisture in above scope is greater than than the tendency of the inclination in the little scope of the first relative humidity 26 with respect to rate of change that is the inclination of relative humidity.In addition, the first relative humidity 26 is generally the degree of 60%RH.
For common active carbon, as shown in absorption isotherm 24, there is the tendency that equilibrium adsorption capacity also increases in the time that the relative humidity of air uprises.
For the adsorbent that strengthening has been carried out in absorption to high humidity, as shown in absorption isotherm 25, the relative humidity of air is from the second relative humidity 27 (φ 2) arrive third phase to humidity 28 (φ 3) scope in the equilibrium adsorption capacity of moisture be greater than less than the second relative humidity 27 or exceed third phase to the inclination in the scope of humidity 28 with respect to rate of change that is the inclination of relative humidity.By pore aperture is consistent in the degree of 10～20nm (nanometer), the degree that the second relative humidity 27 is 80%RH, the degree that third phase is 90%RH to humidity 28.Now, to high humidity absorption carried out strengthening adsorbent at the second relative humidity 27 (φ 2) the equilibrium adsorption capacity 30 (q that locate 2) be less than common silica gel at the first relative humidity 26 (φ 1) the equilibrium adsorption capacity 29 (q that locate 1).And, high humidity absorption has been carried out strengthening adsorbent at third phase to humidity 28 (φ 3) the equilibrium adsorption capacity 31 (q that locate 3) be the maximum equilibrium adsorption capacity 32 (q at relative humidity 100%RH place of common active carbon 4) equal more than.In addition, q 1～q 4value be generally following degree: q 1≈ 0.1, q 2≈ 0.05～0.1, q 3≈ 0.5～0.6, q 4≈ 0.5.
Secondly, use Fig. 7 to Fig. 9 to describe an example of action.About action, to the part identical with embodiment 1, description thereof is omitted.
Same with embodiment 1, air themperature checkout gear 4 detects the air themperature T in the first storage container 1 a, air humidity detection device 5 detects the air humidity H in the first storage container 1 a, lid temperature-detecting device 6 detects the cap surface temperature T of the inner surface (lower surface) of the first storage container cap 1a sur.And then, to make cap surface temperature T surhigher than according to air themperature T awith air humidity H athe dew-point temperature T calculating dew, and air humidity enter the mode of the high humility scope of regulation, humidity environment control device 10 opens and closes lid aperture portion opening and closing shutter 8, to from be arranged at the first storage container cap 1a lid aperture portion 7 capacity, the air humidity in the first storage container 1 is controlled.
In present embodiment 2, at the inner surface of the first storage container cap 1a, be provided with water adsorption device 22 in the mode of blank cap aperture portion 7 herein.Therefore, its moisture before being deflated from lid aperture portion 7 of the highly humid air in the first storage container 1 is adsorbed by water adsorption device 2.
For supporting in the adsorbent of water adsorption device 22, at air humidity H aplace, until reach the equilibrium adsorption capacity shown in the absorption isotherm of Fig. 9, the moisture in absorption the first storage container 1, but in the time arriving equilibrium adsorption capacity, both become cannot moisture absorption also cannot moisture releasing.Then, as air humidity H ain situation about declining, carry out moisture releasing, until reach the equilibrium adsorption capacity at the humidity place after this decline, therefore, air humidity H arise slightly and finally form poised state, humidity absorption and release stops.
On the other hand, air humidity H after arriving equilibrium adsorption capacity ain situation about rising, due to further moisture absorption of adsorbent, therefore air humidity H acontinue to rise.Now, in Fig. 7 and the such structure of Fig. 8, cover aperture portion opening and closing shutter 8 by opening in advance, the humidity of vegetable compartment 400 (outside of the first storage container 1) is lower than the air humidity H in the first storage container 1 a, therefore can will utilize moisture that water adsorption device 22 cannot moisture absorption from lid aperture portion 7 towards vegetable compartment 400 moisture releasings.Now, the adsorbed water component that water adsorption device 22 keeps declines, and therefore the adsorption capacity of water adsorption device 22 is recovered.
Therefore,, as supporting in the adsorbent of water adsorption device 22, use and there is the characterization of adsorption of the absorption isotherm 25 shown in Fig. 9 and high humidity is adsorbed to the adsorbent that has carried out strengthening.And then, by the air humidity control range upper limit humidity H of the air humidity control range having illustrated in the humidity environment control flow chart of Fig. 5 aHbe set in third phase to humidity 28 (φ 3) degree (≈ 90%RH), by air humidity control range lower limit humidity H aLbe set in the second relative humidity 27 (φ 2) degree (≈ 80%RH).Thus, at the humidity range higher to humidity 28 than third phase, there are equilibrium adsorption capacity 31 (q 3) above high absorption capacity, the therefore air humidity H in the first storage container 1 amoisture absorption (dehumidifying), until be less than third phase that equilibrium adsorption capacity sharply declines to humidity 28.And, than the low humidity range of the second relative humidity 27, there are equilibrium adsorption capacity 30 (q 2) following low adsorption capacity, the therefore air humidity H in the first storage container 1 amoisture releasing (humidification), until be greater than the second relative humidity 27 that equilibrium adsorption capacity sharply rises.As a result, can utilize water adsorption device 22 by the air humidity H in the first storage container 1 abe controlled at air humidity control range upper limit humidity H aHwith air humidity control range lower limit humidity H aLbetween humidity range (not in the inner surface dewfall of the first storage container cap 1a and can suppress the best humidity range of the transpiration rate of vegetables load 402).
And, now, cover aperture portion opening and closing shutter 8 by opening, the adsorption moisture that water adsorption device 22 keeps is by vegetable compartment 400 moisture releasings towards low humidity, and the adsorption capacity of water adsorption device 22 is recovered, therefore, effect in embodiment 1, can be at shorter time by air humidity H acontrol as best temperature range, humidity diminishes, and therefore the breathing of vegetables is suppressed, and can further suppress transpiration rate.
And, especially can suppress air humidity H abecome and be greater than air humidity control range upper limit humidity H aHsituation, therefore can avoid reliably the inner surface dewfall at the first storage container cap 1a, and can prevent falling impact on vegetables loads, cause the problems such as mouldy because of the dew being detained because of dew.
In addition, in Fig. 7 and Fig. 8, as supporting in the adsorbent of water adsorption device 22, use has the characterization of adsorption of the absorption isotherm 25 shown in Fig. 9, and the adsorbent of strengthening has been carried out in absorption to high humidity, but, even if as supporting the common silica gel that uses the characterization of adsorption with the absorption isotherm 23 shown in Fig. 9 in the adsorbent of water adsorption device 22, or have in the situation of common active carbon of the characterization of adsorption of absorption isotherm 24, by combining with the open and close controlling of lid aperture portion opening and closing shutter 8, from needless to say also obtaining same effect.
And, in Fig. 7 and Fig. 8, water adsorption device 22 is arranged on to the inner surface (lower surface) of the first storage container cap 1a in the mode of blank cap aperture portion 7, humidity environment control device 10 uses the air themperature T of the first storage container 1 that air themperature checkout gear 4 detects a, the first storage container 1 of detecting of air humidity detection device 5 air humidity H a, use air humidity T awith air humidity H adew-point temperature T in the first storage container 1 calculating dew, and the cap surface temperature T of the inner surface of the first storage container cap 1a of detecting of lid temperature-detecting device 6 surcover the open and close controlling of aperture portion opening and closing shutter 8, regulate the Bas Discharged amount from lid aperture portion 7.But, for water adsorption device 22, the generally higher equilibrium adsorption capacity of air humidity more (adsorption capacity increases), and, when humidity in the time carrying out water adsorption, in the first storage container 1 is high, because of the temperature rise of heat of adsorption water adsorption device 22, lower than dew-point temperature T dewpossibility step-down.Thereby, also can delete for calculating dew-point temperature T dewair themperature checkout gear 4 and for dew-point temperature T dewthe lid temperature-detecting device 6 comparing, only utilizes air humidity detection device 5 to control.

Figure 10 is the stereogram that is arranged at the vegetable compartment container in refrigerator in embodiment 3 of the present utility model.And Figure 11 is the Sketch figure of the refrigerator vegetable chamber in embodiment 3 of the present utility model, and it is the cutaway view of observing from the side the first storage container 1.In addition, in Figure 10 and Figure 11, omit the explanation to the position identical with embodiment 1.
Storage container inner cap 33 (being equivalent to the mobile wall in the utility model) is the parts of the volume for changing the first storage container 1, and storage container inner cap drive unit 34 is the parts for making 33 liftings of storage container inner cap.Storage container inner cap drive unit 34 (being equivalent to the mobile device in the utility model) for example forms by rotation motor with for the track that inner cap is guided.; in present embodiment 3; the detected value of humidity environment control device 10 based on air themperature checkout gear 4, air humidity detection device 5 and lid temperature-detecting device 6 drives storage container inner cap drive unit 34 (in other words for changing the volume in the first storage container 1), will in the first storage container 1, be controlled at the humidity range (dewfall and inner cap do not suppress the best humidity range of the transpiration rate of vegetables load 402 at the inner surface of the first storage container cap 1a) of expectation.That is, in present embodiment 3, the humidity conditioner that humidity environment control device 10 and storage container inner cap drive unit 34 are equivalent in the utility model.In addition, in present embodiment 3, lid temperature-detecting device 6 be arranged on storage container inner caps 33 (private side of first storage container 1) different from embodiment 1 and 2 (being arranged at the rear side of the first storage container cap 1a).
Secondly, use Figure 10 and Figure 11 to describe an example of action.About action, omit the explanation to the position identical with embodiment 1.
The first storage container 1 is formed as air-tight state or semi-hermetic state by the first storage container cap 1a and storage container inner cap 33, is therefore maintained at high humility, and the transpiration of vegetables is suppressed.But, in the time that excess moisture in the first storage container 1 rises, there is the possibility that produces following problem: in the interior generation dewfall of the first storage container 1, rot because dew causes making vegetables load 402, cause mouldy etc. because of the dew being detained.
Herein, known according to the measured data shown in Fig. 4 (a) (being kept at the measured data of the weight slip of the actual vegetables load of (more than humidity 90%RH) in the first storage container 1): the kind of being not only the vegetables load that transpiration is different, even if for identical vegetables load, also can cause because varying in weight transpiration rate difference.Therefore, can predict: be not only the kind of the vegetables load that transpiration is different, even if for identical vegetables load, owing to varying in weight, the rising trend of humidity in the first storage container 1 and the generation of dewfall tendency are also different.Herein, the difference of the weight of vegetables loads also can be regarded vegetables load shared volume ratio poor in storage container as.That is, volume ratio is less, and the temperature rise dull of the first storage container 1 entirety more easily spreads from the generation moisture of vegetables load, and therefore transpiration is promoted.Thereby, as shown in Figure 10 and Figure 11, by making 33 liftings of storage container inner cap, the volumetric change of the first storage container 1 is become to be suitable for the volume of vegetables load, can control the humidity in the first storage container 1.
Figure 12 is the humidity environment control flow chart of the refrigerator vegetable chamber (the first storage container 1) in embodiment 3 of the present utility model, and is the figure that the Control the content of the illustrated humidity environment control device 10 of Figure 11 is shown.In addition, in the step the step S1 carrying out except user, do not express the action of the main body of moving and all undertaken by humidity environment control device 10.
First,, in step S1, in the time that the first storage container cap 1a and storage container inner cap 33 open and close, in step S2, air themperature checkout gear 4 detects the air themperature T in the first storage container 1 a.And air humidity detection device 5 detects the air humidity H in the first storage container 1 a.In addition, in step S1, putting into and/or take out independently of the first storage container cap 1a and the first storage container cap 1a and vegetables load 402 opens and closes.
In step S3, the air themperature T that uses air themperature checkout gear 4 to detect athe air humidity H detecting with air humidity detection device 5 acalculate the dew-point temperature T in the first storage container 1 dew.In step S4, lid temperature-detecting device 6 detects the cap surface temperature T of the inner surface (lower surface) of storage container inner cap 33 sur, and in step S5 to cap surface temperature T surwith dew-point temperature T dewmagnitude relationship compare.Now, when being judged to be cap surface temperature T surat dew-point temperature T dewin following situation, exist in the inner surface of storage container inner cap 33 dewfall or the possibility of dewfall immediately.Thereby, with air humidity H avalue irrelevant, advance to step S13 and send towards storage container inner cap drive unit 34 control signal that makes storage container inner cap 33 rising one-levels.
When be judged to be cap surface temperature T in step S5 surbe greater than dew-point temperature T dewsituation under, advance to step S6, relatively air humidity H awith predefined air humidity control range upper limit humidity H aHmagnitude relationship.Now, when being judged to be air humidity H abe greater than air humidity control range upper limit humidity H aHsituation under, be judged as in the possibility of the inner surface dewfall of storage container inner cap 33 high, even and if suppress vegetables load 402 transpiration rate aspect be also too high humidity.Thereby, advance to step S13 and send the control signal that makes storage container inner cap 33 rising one-levels towards storage container inner cap drive unit 34.
When be judged to be air humidity H in step S6 aat air humidity control range upper limit humidity H aHin following situation, advance to step S7, relatively air humidity H awith predefined air humidity control range lower limit humidity H aLmagnitude relationship.Now, when being judged to be air humidity H abe less than air humidity control range lower limit humidity H aLsituation under, be judged as humidity deficit for suppressing the transpiration rate of vegetables load 402, and low in the possibility of the inner surface dewfall of storage container inner cap 33.Thereby, advance to step S14 and send the control signal that makes storage container inner cap 33 decline one-levels towards storage container inner cap drive unit 34.
When be judged to be air humidity H in step S7 aat air humidity control range lower limit humidity H aLin above situation, be judged as air humidity H abe contained in air humidity control range upper limit humidity H aHwith air humidity control range lower limit humidity H aLbetween, not in the inner surface dewfall of storage container inner cap 33 and can suppress the best humidity range of the transpiration rate of vegetables load 402, return to step S2, repeat step S2～S7.
The in the situation that of storage container inner cap 33 lifting in step S13 or S14, in step S15 by the elapsed time t after storage container volumetric change pastafter replacement, instrumentation elapsed time t in step S16 past(calculating the elapsed time after resetting).
Secondly, in step S17, relatively elapsed time t pastwith the percent opening stand-by time t after changing after predefined storage container volumetric change waitmagnitude relationship.
As the elapsed time t being judged to be after storage container volumetric change pastpercent opening after storage container volumetric change is stand-by time t after changing waitin above situation, be judged as for the lifting because of storage container inner cap 33 and passed through the sufficient time the interior generation humidity of the first storage container 1 changes, return to step S2, repeat step S2～S17.
As the elapsed time t being judged to be after storage container volumetric change pastbe less than the percent opening stand-by time t after changing after storage container volumetric change waitsituation under, be judged as produce in the first storage container for the lifting because of storage container inner cap 33 humidity change not yet pass through the sufficient time, return to step S16, repeat step S16～S17.
To sum up, in the refrigerator 1000 forming as present embodiment 3, as the interior storage container inner cap 33 that arranges of the first storage container 1 of closed container roughly, detect the air themperature in the first storage container 1, the inner surface temperature of air humidity and storage container inner cap 33, to make inner surface temperature higher than the dew-point temperature calculating according to air themperature and air humidity, and air humidity enters the mode of the high humility scope of regulation, make 33 liftings of storage container inner cap, it is the volume that is applicable to vegetables load by the volumetric change of the first storage container 1, control the air humidity in the first storage container 1, can obtain thus following effect: with the kind of basis at the vegetables load 402 of inside keeping, amount and different transpiration rate is irrelevant, can be in the inner surface dewfall of storage container inner cap 33, and can suppress the transpiration of vegetables load 402.Particularly in the situation that inner surface temperature is below dew-point temperature, irrelevant with air humidity, preferentially by making storage container inner cap 33 increase, dew-point temperature is declined, therefore the inner surface dewfall at storage container inner cap 33 can be avoided reliably, the problem such as mouldy causing because of the impact on vegetables load 402 that falling of dew causes, because of the dew being detained can be prevented.And, between the first storage container cap 1a and storage container inner cap 33, also become roughly closed container, this place's performance is as the effect of insulating air layer, therefore, because the impact of returning to the temperature change that the cold emission of wind path 410 causes from vegetable compartment tails off, the breathing of vegetables is suppressed, and therefore can obtain the effect that can further suppress transpiration rate, maintain freshness.
In addition, in Figure 10 and Figure 11, be formed as utilizing guide rail to guide a part for storage container inner cap 33, and carry out the structure of lifting action by rotation motor, but this structure there is no the special restriction.For example also can utilize spring etc. from the first storage container cap 1 side, storage container inner cap 33 is pressed into or is utilized electromagnet etc. to pull it and makes it lifting.And, also can make storage container inner cap 33 vertically erect, and make it along front and back or left and right directions slip.As long as can change by storage container inner cap 33 volume of the first storage container 1, just can control the air humidity in the first storage container 1, therefore can obtain same effect.
And, in Figure 10～Figure 12, use the air themperature T of the first storage container 1 being detected by air themperature checkout gear 4 a, the first storage container 1 of being detected by air humidity detection device 5 air humidity H a, use air themperature T awith air humidity H adew-point temperature T in the first storage container 1 calculating dew, by the cap surface temperature T of the inner surface (lower surface) of the storage container inner cap 33 that detects of lid temperature-detecting device 6 sur, carry out the lifting action of storage container inner cap 33, regulate the volume of the first storage container 1, but, even if in the time of storage container inner cap 33 lifting action, same during also with lid aperture portion opening and closing shutter 8 on-off action, as shown in the measured data of Fig. 6, imaginary air themperature 14 (T a) and cap surface temperature 17 (T sur) except after the first storage container cap 1a and storage container inner cap 33 have have just opened and closed, be equal temperature, therefore, also can delete either party's temperature-detecting device, and use the detected value of the opposing party's temperature-detecting device to be replaced, and, also can be formed as: checkout gear is only air humidity detection device 5, by air humidity H aupper limit humidity H aHset lowlyer, by lower limit humidity H aLset highlyer, control with narrower air humidity control range.Although accuracy of detection declines slightly owing to having cut down checkout gear, can realize cost degradation, and can be by the air humidity H of the first storage container 1 abe controlled at and be difficult to produce dewfall and can suppress the humidity range of the transpiration of vegetables load 402 at the inner surface of storage container inner cap 33, therefore can obtain roughly equal effect.
And, in Figure 12, for the down maneuver of the storage container inner cap 33 in vertical motion, the step S14 of the storage container inner cap 33 in step S13, humidity environment control device 10 so that must be respectively the mode of each lifting one-level transmit control signal towards storage container inner cap drive unit 34, but also can not be fixed on one-level.For example,, when being judged to be cap surface temperature T surat dew-point temperature T dewin following situation (step S5 is), more than making storage container inner cap 33 rising two-stages, or make it to rise to the upper limit.And, for example, also can be formed as: as air humidity H abe greater than air humidity control range upper limit humidity H aHtime (step S6 is) and be less than air humidity control range lower limit humidity H aLsituation under (step S7 is), air humidity H athe larger progression that more increases the lifting action of storage container inner cap 33 of difference with air humidity control range.Like this, the air humidity H of the first storage container 1 acontrol accuracy improve, can prevent more reliably the inner surface dewfall at storage container inner cap 33, and can suppress the transpiration of vegetables load 402.
And, in present embodiment 3, the first storage container cap 1a and storage container inner cap 33 are set, be formed as insulating air layer by between the two, still, and in present embodiment 3, the first storage container cap 1a nonessential structure.Even if in the situation that there is no the first storage container cap 1a, only storage container inner cap 33 being set, also can the humidity range (not in the inner surface dewfall of the first storage container cap 1a and can suppress the best humidity range of the transpiration rate of vegetables load 402) of expectation will be controlled in the first storage container 1.
And, in present embodiment 3, change the volume in the first storage container 1 by storage container inner cap 33 is moved, but can certainly make other wall (for example side) mobile.

Figure 13 is the stereogram that is arranged at the vegetable compartment container in refrigerator in embodiment 4 of the present utility model.And Figure 14 is the Sketch figure of the refrigerator vegetable chamber in embodiment 4 of the present utility model, and it is the cutaway view of observing from the side the first storage container 1.
In Figure 13 and Figure 14, for the position identical with embodiment 1～3, description thereof is omitted, and the 22nd, the water adsorption device having illustrated in embodiment 2, is arranged at the part of the inner surface (lower surface) of storage container inner cap 33.
Water adsorption device 22 support the characterization of adsorption of the absorption isotherm 23 having shown in Fig. 9 common silica gel, there is common active carbon of the characterization of adsorption of absorption isotherm 24 etc. and have with respect to highly humid air the adsorbent of more characterization of adsorption.The adsorbent of strengthening has been carried out in the absorption to high humidity as porous silica material especially preferably with pore characterization of adsorption, that be provided with the degree of multiple 10～20nm (nanometer) of absorption isotherm 25.
Secondly, use Figure 13 and Figure 14 to describe an example of action.About action, for the position identical with embodiment 1～3, description thereof is omitted.
Same with embodiment 3, storage container inner cap 33 is arranged in the first storage container 1 of closed container roughly, detect the inner surface temperature of air themperature, air humidity and storage container inner cap 33 in the first storage container 1.And then, to make cap surface temperature T surbeguine is according to air themperature T awith air humidity H athe dew-point temperature T calculating dewthe mode that high and air humidity enters the high humility scope of regulation makes 33 liftings of storage container inner cap, is the volume that is applicable to vegetables load by the volumetric change of the first storage container 1, controls the air humidity in the first storage container 1.
, in present embodiment 4, be provided with water adsorption device 22 in a part for the inner surface (lower surface) of storage container inner cap 33 herein, therefore, the moisture in highly humid air is adsorbed by water adsorption device 22 simultaneously.And then, as supporting in the adsorbent of water adsorption device 22, use the absorption to high humidity of the characterization of adsorption with the absorption isotherm 25 shown in Fig. 9 to carry out the adsorbent of strengthening.And, by air humidity control range upper limit humidity H shown in Figure 12, air humidity control range aHbe set as third phase to humidity 28 (φ 3) degree (≈ 90%RH), by air humidity control range lower limit humidity H aLbe set as the second relative humidity 27 (φ 2) degree (≈ 80%RH).
Therefore, higher than third phase to the humidity range of humidity 28 in, there are equilibrium adsorption capacity 31 (q 3) above high absorption capacity, the therefore air humidity H in the first storage container 1 aby moisture absorption (dehumidifying), be less than third phase that equilibrium adsorption capacity sharply declines to humidity 28 until become.And, in the humidity range lower than the second relative humidity 27, there are equilibrium adsorption capacity 30 (q 2) following low adsorption capacity, the therefore air humidity H in the first storage container 1 aby moisture releasing (humidification), be greater than until become the second relative humidity 27 that equilibrium adsorption capacity sharply rises., by the air humidity H in water adsorption device 22, the first storage containers 1 abe maintained at air humidity control range upper limit humidity H aHwith air humidity control range lower limit humidity H aLbetween humidity.Thereby, can be controlled to not in the inner surface dewfall of storage container inner cap 33 and can suppress the best humidity range of the transpiration rate of vegetables load 402., owing to being to suppress air humidity H abecome and be greater than air humidity control range upper limit humidity H aH, therefore can avoid reliably the dewfall of the inner surface of storage container inner cap 33, can prevent the impact on vegetables load that causes because of falling of dew or cause mouldy etc. problem because of the dew being detained.In addition, as support in the adsorbent of water adsorption device 22, can certainly use the absorption isotherm 23 having shown in Fig. 9 characterization of adsorption common silica gel or there is the common active carbon of the characterization of adsorption of absorption isotherm 24.By combining with the elevating control of storage container inner cap 33, from needless to say also obtaining same effect.
And, in the structure shown in Figure 13 and Figure 14, between the first storage container cap 1a and storage container inner cap 33, become roughly closed container.This is the effect of closed container performance insulating air layer roughly, therefore, because the impact of returning to the temperature change that the cold emission of wind path 410 causes from vegetable compartment diminishes, and can carry out moisture absorption/moisture releasing by water adsorption device 22 and carry out humidity control.Thereby, the effect in embodiment 3, can be at shorter time by air humidity H abe controlled to best humidity range, humidity variation also diminishes, and therefore, the breathing of vegetables is suppressed, and can further suppress transpiration rate and maintains freshness.
In addition, in Figure 13 and Figure 14, water adsorption device 22 is arranged at a part for the inner surface (lower surface) of storage container inner cap 33, but, also can or comprise side, bottom surface in interior whole inner surface setting at the first storage container 1 in the inner surface entirety of storage container inner cap 33.When water adsorption device 22 being arranged in the situation of a part of the storage container inner cap 33 that surface temperature possibility minimum and dewfall is high, can realize the object that suppresses dewfall with low cost.In addition, increase area is set, more can avoid more reliably dewfall.
And, in Figure 13 and Figure 14, water adsorption device 22 is arranged to a part for the inner surface (lower surface) of storage container inner cap 33, in addition, use the air themperature T of the first storage container 1 being detected by air themperature checkout gear 4 a, the first storage container 1 of being detected by air humidity detection device 5 air humidity H a, use air themperature T awith air humidity H adew-point temperature T in the first storage container 1 calculating dew, by the cap surface temperature T of the inner surface of the storage container inner cap 33 that detects of lid temperature-detecting device 6 surcarry out the lifting action of storage container inner cap 33, it is the volume that is applicable to vegetables load by the volumetric change of the first storage container 1, control the air humidity in the first storage container 1, still, for water adsorption device 22, the general higher equilibrium adsorption capacity of air humidity more (adsorption capacity increases), and, when humidity in the time of adsorption moisture, in the first storage container 1 is high, by heat of adsorption, the temperature rise of water adsorption device 22, lower than dew-point temperature T dewpossibility step-down, therefore also can delete for calculating dew-point temperature T dewair themperature checkout gear 4 and for dew-point temperature T dewthe lid temperature-detecting device comparing, only uses air humidity detection device 5 to control.Even if water adsorption device 22 monomers also can carry out humidity regulation, especially as air humidity H afor the adsorption capacity in the situation of high humility is high, therefore can on the basis of realizing cost degradation, obtain equal effect.

Secondly, use Figure 15 to describe an example of action.About action, for the position identical with embodiment 4, description thereof is omitted.
In Figure 15, the effect of roughly closed container between the first storage container cap 1a and storage container inner cap 33 performance insulating air layer, therefore, because the impact of returning to the temperature change that the cold emission of wind path 410 causes from vegetable compartment diminishes.In this case, implement hydrophily by the inner surface at storage container inner cap 33 (lower surface) and apply 35, the in the situation that of thickness 0.5mm, can reduce about 8% hot percent of pass, the in the situation that of thickness 1.0mm, can reduce about 15% hot percent of pass.In applying 35, hydrophily for example uses the coating agent that thermal conductivity factor is 0.04W/mK herein.
Thereby, apply 35 layer due to hydrophily and also form heat insulation layer and suppress temperature change, therefore, the effect in embodiment 3, the breathing of vegetables is suppressed, and can further suppress transpiration rate and maintains freshness.And, coating agent has hydrophily, thus, even if suppose in the case of the inner surface generation dewfall of storage container inner cap 33, dew is also expanded equably in inner surface entirety, can suppress falling of dew, therefore can prevent direct impact on vegetables load 402 or cause the problems such as mouldy because of the dew being detained.
In addition, in present embodiment 5, replace and water adsorption device 22 is set and enforcement hydrophily coating 35, apply 35 but also can implement hydrophily at the inner surface of the first storage container 1 (at the inner surface of the first storage container 1, the parts that water adsorption device 22 forms being set) shown in embodiment 4.And, in present embodiment 5, to being illustrated at the example of implementing hydrophily coating 35 by the first storage container that regulates internal capacity to control interior humidity, apply 35 but can certainly for example, implement hydrophily at the inner surface that regulates the first storage container 1 (parts shown in embodiment 1,2) that control interior humidity from covering the Bas Discharged amount of aperture portion 7.

Secondly, use Figure 16 to describe an example of action.About action, for the position identical with embodiment 1～3, description thereof is omitted.
The first storage container 1 is formed as air-tight state or semi-hermetic state by the first storage container cap 1a and storage container inner cap 33, therefore can maintain high humility, and the transpiration of vegetables is suppressed.But, in the time that the humidity in the first storage container 1 is too high, exists and produce the possibility of following temperature: in the interior generation dewfall of the first storage container 1, rot because dew makes vegetables load, or cause mouldy etc. because of the dew being detained.
Now, in present embodiment 6, the lid aperture portion 7a of the first storage container is arranged on to the position being communicated with the first storage container 1 of storage container inner cap 33, same with embodiment 1, the inner surface temperature of air themperature, air humidity and storage container inner cap 33 in detection the first storage container 1.And then, open and close the lid aperture portion opening and closing shutter 8a of the first storage container in the mode that makes inner surface temperature enter the high humility scope of regulation higher than the dew-point temperature calculating according to air themperature and air humidity and air humidity, control from the capacity of the lid aperture portion 7a of the first storage container, i.e. air humidity in the first storage container 1.Thus, from irrelevant according to the different and different transpiration rate of the kind of the vegetables load 402 in the first storage container 1 interior keeping, amount, can obtain not in the inner surface dewfall of storage container inner cap 33 and can suppress the effect of the transpiration of vegetables load 402.
And, in present embodiment 6, also be provided with the lid aperture portion 7b of the second storage container in the position being communicated with the second storage container 2 of storage container inner cap 33, therefore, highly humid air in the first storage container 1 from the lid aperture portion 7a of the first storage container is discharged from flows into leak tightness and humidity the second storage container 2 inside lower than the first storage container 1 via air adiabatic layer 36 from the lid aperture portion 7b of the second storage container, can make highly humid air circulate in the lower container of humidity, guarantee humidity even if also the transpiration of vegetables can be suppressed to a certain extent in the second storage container 2.
Now, vegetable compartment 400 is by returning to the cold emission of wind path 410 from the vegetable compartment that is disposed at end face and being cooled, therefore, the temperature of air adiabatic layer 36 that is arranged on the position of comparing the first storage container 1 and the second storage container 2 top sides is minimum, therefore, when highly humid air flows in the situation of air adiabatic layer 36, high in the possibility of the first storage container cap 1a dewfall.But, even if dewfall occurs hypothesis, also can utilize storage container inner cap 33 Antidewing water droplets to drop down onto in storage container, if the first storage container cap 1a is formed as loading and unloading, can be unloaded and cleaned.Therefore, air adiabatic layer 36 (reduces the impact because return to the temperature change that the cold emission of wind path 410 causes from vegetable compartment as the effect of heat insulation layer except performance, the breathing that suppresses vegetables is transpiration rate, maintain the effect of freshness) outside, can also prevent the problem such as mouldy causing because of the impact on vegetables load 402 that falling of dew causes, because of the dew being detained.
In present embodiment 6, be provided with the lid aperture portion opening and closing shutter 8b of the second storage container and the opening and closing shutter drive unit 9b of the second storage container of the percent opening of the lid aperture portion 7b that controls the second storage container herein.In this case, also can make the lid aperture portion opening and closing shutter 8b of the second storage container and the lid aperture portion opening and closing shutter 8a of the opening and closing shutter drive unit 9b of the second storage container and the first storage container and the opening and closing shutter drive unit 9a of the first storage container interlock and control.In detail, when in the large situation of the percent opening of the lid aperture portion 7a of the first storage container, the humidity of the first storage container 1 inside is high and exist in the situation of possibility of dewfall, can control to make the percent opening of lid aperture portion 7b of the second storage container also become large mode.Thus, the internal circulating load from the first storage container 1 towards the highly humid air of the second storage container 2 increases, and therefore, not only can suppress the dewfall of the first storage container 1 inside, and the air humidity of the second storage container 2 inside rises.On the contrary, when in the little situation of the percent opening of the lid aperture portion 7a of the first storage container, the load of the first storage container 1 inside is little and in situation that humidity is low, can control in the mode that the percent opening of lid aperture portion 7b of the second storage container is also diminished.Thus, concentrated cold air from air adiabatic layer 36 towards the second storage container 2 flows into and is suppressed, and can will in the second storage container 2, maintain middle humidity band, therefore, not only in the first storage container 1, and in the second storage container 2, also can guarantee to suppress the rising humidity of vegetables.
In addition, the vegetable compartment container 401 shown in Figure 16 is an example after all, for example, also can form vegetable compartment container 401 in the mode shown in Figure 17.
Figure 17 is another routine Sketch figure that the refrigerator vegetable chamber in embodiment 6 of the present utility model is shown, and is the cutaway view of observing from the side the first storage container 1 and the second storage container 2.
In Figure 17, the first storage container 1 is arranged on the top (or inner) of the second storage container 2.And then the first storage container 1 shares the first storage container cap 1a and the storage container inner cap 33 of the upper opening that covers the second storage container 2, is formed as thus the structure that the first storage container 1 is connected with the wall of the second storage container 2.And, in Figure 17, the second storage container peristome 2a is formed to the sidewall of the rear side of the second storage container 2.Even if form by this way vegetable compartment container 401, also can obtain the effect identical with the vegetable compartment container 401 shown in Figure 16.
And, in Figure 17, the lid aperture portion opening and closing shutter 8b one of the lid aperture portion opening and closing shutter 8a of the first storage container and the second storage container is changed into a lid aperture portion opening and closing shutter 8, the opening and closing shutter drive unit 9b one of the opening and closing shutter drive unit 9a of the first storage container and the second storage container is changed into an opening and closing shutter drive unit 9.And then the percent opening of the lid aperture portion 7b of the lid aperture portion 7a according to the inner surface temperature of the air themperature in the first storage container 1, air humidity and storage container inner cap 33 to the first storage container and the second storage container is summed up control.Thus, for example, when in the situation of possibility that has the first storage container 1 interior dewfall, can increase the percent opening of the lid aperture portion 7a of the first storage container and the lid aperture portion 7b of the second storage container.And, for example, when in the low situation of the humidity in the first storage container 1, can dwindle the percent opening of the lid aperture portion 7a of the first storage container and the lid aperture portion 7b of the second storage container.Thereby, when in the situation of percent opening of lid aperture portion 7b of adjusting the second storage container, by the lid aperture portion opening and closing shutter 8b one of the lid aperture portion opening and closing shutter 8a of the first storage container and the second storage container being changed into a lid aperture portion opening and closing shutter 8, the opening and closing shutter drive unit 9b one of the opening and closing shutter drive unit 9a of the first storage container and the second storage container is changed into an opening and closing shutter drive unit 9, can on the basis of cutting down number of components, obtain same effect.
And, in Figure 16 and Figure 17, only at the interior air themperature checkout gear 4 that arranges of the first storage container 1, air humidity detection device 5 and lid temperature-detecting device 6, according to the air themperature in the first storage container 1, the percent opening of the inner surface temperature control lid aperture portion 7 of air humidity and storage container inner cap 33, but also can be same with the first storage container 1, detect the air themperature in the second storage container 2, air humidity, the inner surface temperature of storage container inner cap 33, and the percent opening of the lid aperture portion 7b of the second storage container that control is communicated with the second storage container 2 individually.Thus, the humidity in the second storage container 2 becomes lower than the humidity in the first storage container 1, but by the second storage container peristome 2a, humidity control accuracy improves.Therefore, although can form transpiration rate unlike the such as storage space of the vegetables of the so much applicable long-time preservation of the leaf vegetables such as Chinese cabbage, root-mustard at the second storage container 2.
And, also can to the vegetable compartment container 401 shown in Figure 16 and Figure 17 (in the position being communicated with the first storage container 1 and the second storage container 2 of storage container inner cap 33, the lid aperture portion 7a of the first storage container and the lid aperture portion 7b of the second storage container are set, make highly humid air in the first storage container 1 from the lid aperture portion 7a of the first storage container is discharged from via air adiabatic layer 36 from the lid aperture portion 7b of the second storage container towards leak tightness and the vegetable compartment container of low the second storage container 2 inner loop of humidity ratio the first storage container 1) further append structure as shown in figure 18.
Figure 18 is the Sketch figure that the another example of the refrigerator vegetable chamber in embodiment 6 of the present utility model is shown.
In the vegetable compartment container 401 shown in Figure 18, except the structure of the vegetable compartment container 401 shown in Figure 17, the lid aperture portion opening and closing shutter 8c of the air adiabatic layer that be provided with the lid aperture portion 7c of air adiabatic layer at the first storage container cap 1a suitable with the cooling surface of air adiabatic layer 36, opens and closes for the lid aperture portion 7c of point multistage ground-to-air thermosphere of drawing last breath and for driving the opening and closing shutter drive unit 9c of air adiabatic layer of lid aperture portion opening and closing shutter 8c of air adiabatic layer.
As mentioned above, in present embodiment 6, when the humidity of the first storage container 1 inside high and exist in the situation of possibility of dewfall, become large mode with the percent opening of lid aperture portion (the lid aperture portion 7a of the first storage container, the lid aperture portion 7b of the second storage container) that the first storage container 1 and the second storage container 2 are communicated with and control, the internal circulating load from the first storage container 1 towards the highly humid air of the second storage container 2 is increased.But, there is the first storage container 1 interior overload etc. and situation that humidity does not decline.In this case, by increasing the percent opening of lid aperture portion 7c of air adiabatic layer, making increases towards the capacity of vegetable compartment 400, humidity in air adiabatic layer 36 and the first storage container 1 declines, and the situation that therefore suppresses the dewfall in air adiabatic layer 36 and the first storage container 1 becomes possibility.And, when being maintained in the situation of optimum humidity in the first storage container 1, by dwindle air adiabatic layer lid aperture portion 7c percent opening or by its obstruction, internal circulating load from the first storage container 1 towards the highly humid air of the second storage container 2 increases, therefore, even if also can guarantee to suppress the rising humidity of vegetables in the second storage container 2.In addition, and nonessential lid aperture portion 7c at air adiabatic layer the lid aperture portion opening and closing shutter 8c of air adiabatic layer and the opening and closing shutter drive unit 9c of air adiabatic layer are set.For example, if imaginary the first storage container 1 interior overload etc. and situation that humidity does not decline etc. also preset the percent opening of air adiabatic layer, can unload the lid aperture portion opening and closing shutter 8c of air adiabatic layer and the opening and closing shutter drive unit 9c of air adiabatic layer.
Herein, the lid aperture portion 7c of air adiabatic layer is equivalent to the 3rd aperture portion in the utility model.And the lid aperture portion opening and closing shutter 8c of air adiabatic layer and the opening and closing shutter drive unit 9c of air adiabatic layer are equivalent to the 3rd aperture portion opening and closing device in the utility model.
Like this, except being arranged on the lid aperture portion 7a of the first storage container and the lid aperture portion 7b of the second storage container of the position being communicated with the first storage container 1 and the second storage container 2 of storage container inner cap 33, form the lid aperture portion 7c of air adiabatic layer at the first storage container cap 1a suitable with the cooling surface of air adiabatic layer 36, according to the air themperature in the first storage container 1, the inner surface temperature of air humidity and storage container inner cap 33, combine the lid aperture portion 7a of the first storage container, the percent opening of the lid aperture portion 7c of the lid aperture portion 7b of the second storage container and air adiabatic layer is controlled, thus, can adjust the internal circulating load from the first storage container 1 towards the highly humid air of the second storage container 2, and capacity from air adiabatic layer 36 towards vegetable compartment 400.Thus, can obtain following effect: can suppress the dewfall of the first storage container 1, the second storage container 2 and air adiabatic layer 36 inside, and can be suppressed at the transpiration of the vegetables that the first storage container 1 and the second storage container 2 preserve and guarantee humidity.
Figure 19 is the example that the measured data of the dewfall amount in transpiration rate (=water transpiration weight/initial stage weight) and the vegetable compartment container of the vegetables load under all size of the related vegetable compartment container of embodiment 6 of the present utility model is shown, (a) be the data of the transpiration rate of vegetables load 402, (b) be the data of the dewfall amount of storage container.A～D shown in transverse axis represents the specification of vegetable compartment container 401.Specifically, A is the vegetable compartment container that has unloaded the individual layer lid specification of the first storage container cap 1a from the vegetable compartment container 401 shown in Figure 17.In the vegetable compartment container 401 of this A specification, the Area Ratio for lid aperture portion with respect to storage container inner cap 33, the lid aperture portion 7a of the first storage container is that the lid aperture portion 7b of about 1.2%, the second storage container is about 0.6%.B is the vegetable compartment container 401 of the Double layer lid specification shown in Figure 17.In the vegetable compartment container 401 of this B specification, Area Ratio for lid aperture portion with respect to storage container inner cap 33, same with the vegetable compartment container of A specification, the lid aperture portion 7a of the first storage container is that the lid aperture portion 7b of about 1.2%, the second storage container is about 0.6%.C is the vegetable compartment container 401 shown in Figure 18., C is the vegetable compartment container that is formed with the lid aperture portion 7c of air adiabatic layer at the first storage container cap 1a of the upper cover as Double layer lid.In the vegetable compartment container 401 of this C specification, Area Ratio for lid aperture portion with respect to storage container inner cap 33, same with the vegetable compartment container of A specification, the lid aperture portion 7a of the first storage container is that the lid aperture portion 7b of about 1.2%, the second storage container is for being greater than 0.6%.And the lid aperture portion 7c that is formed at the air adiabatic layer of the first storage container cap 1a is about 0.2% with respect to the Area Ratio of storage container inner cap 33.D is the vegetable compartment container 401 shown in Figure 18, is to change with respect to the vegetable compartment container of C specification the area that covers aperture portion, makes the optimized vegetable compartment container of aperture area.In the vegetable compartment container 401 of this D specification, the Area Ratio for lid aperture portion with respect to storage container inner cap 33, the lid aperture portion 7a of the first storage container is that the lid aperture portion 7b of about 0.8%, the second storage container is about 0.2%.And the lid aperture portion 7c that is formed at the air adiabatic layer of the first storage container cap 1a is about 0.2% with respect to the Area Ratio of storage container inner cap 33.
And the transpiration rate of the vegetables load shown in Figure 19 illustrates the transpiration rate that is stored in the spinach of the first storage container 1 or the second storage container 2 as vegetables load.In detail, 37a is when the transpiration rate in the time that the first storage container 1 is preserved the spinach of high load capacity amount (300g).37b is when the transpiration rate in the time that the first storage container 1 is preserved the spinach of underload amount (100g).37c is when the transpiration rate in the time that the second storage container 2 is preserved the spinach of high load capacity amount (800g).37d is when the transpiration rate in the time that the second storage container 2 is preserved the spinach of underload amount (200g).Mostly the load of why preserving at the second storage container 2 is because consistent with the capacity of storage container.And, 38a illustrates when the dewfall amount in the first storage container 1 in the time that the first storage container 1 is preserved the spinach of high load capacity amount (300g), 38b illustrates when the dewfall amount in the first storage container 1 in the time that the first storage container 1 is preserved the spinach of underload amount (100g), 38c illustrates that, when the dewfall amount in the second storage container 2 in the time that the second storage container 2 is preserved the spinach of high load capacity amount (800g), 38d illustrates when the dewfall amount in the second storage container 2 in the time that the second storage container 2 is preserved the spinach of underload amount (200g).
Known according to Figure 19, by changing to Double layer lid specification (B) from individual layer lid specification (A), by the effect of cut-in without ball heat insulation layer 36, thereby the impact that can reduce the temperature change that the cold emission because return to wind path 410 from vegetable compartment causes suppresses the breathing of vegetables, and therefore the transpiration rate of spinach is suppressed.Particularly the transpiration rate of the vegetables of underload is suppressed (37b, 37d).But, by changing to Double layer lid specification (B) from individual layer lid specification (A), thereby improving hydrofuge amount, leak tightness is suppressed, and therefore under all conditions, dewfall amount increases.Secondly, known: by changing to upper cover perforate specification (C) from Double layer lid specification (B), superfluous hygroscopic water is by towards vegetable compartment 400 moisture releasings, and therefore the dewfall amount of the first storage container 1 reduces (38a, 38b).But because the inflow of the cold air from vegetable compartment 400 towards the first storage container 1 and the second storage container 2 becomes many, therefore the dewfall amount of the second storage container 2 increases (38c, 38d).In addition, known: by changing to perforated area optimization specification (D) from upper cover perforate specification (C), the dewfall amount of the second storage container 2 is also suppressed (38c, 38d).This be because: by changing to perforated area optimization specification (D) from upper cover perforate specification (C), the area of the lid aperture portion 7b of the lid aperture portion 7a of the first storage container and the second storage container diminishes, therefore, reduce from the hydrofuge amount of the first storage container 1, reduce towards the internal circulating load of the second storage container 2, increase from the moisture releasing amount of the lid aperture portion 7c of air adiabatic layer.

Figure 20 is the Sketch figure of the refrigerator vegetable chamber in embodiment 7 of the present utility model, and is the cutaway view of observing from the side the first storage container 1 and the second storage container 2.Herein, same with Figure 17, Figure 20 is formed as the top (or inner) that the first storage container 1 is arranged on the second storage container 2, shares the structure of the first storage container cap 1a and storage container inner cap 33.In addition, in Figure 20, for the position identical with embodiment 6, description thereof is omitted.
In Figure 20, be provided with in the boundary face with the second storage container 2 of the first storage container 1 and connect the storage container openings 39 (through hole) of the first storage container 1 and the second storage container 2, open and close the storage container openings opening and closing shutter 40 of storage container openings 39 and for driving the opening and closing shutter drive unit 9d of storage container openings of storage container openings opening and closing shutter 40 for point multistage.The opening and closing shutter drive unit 9d of storage container openings for example forms by rotation motor with for the track that gate is guided.; in present embodiment 7; humidity environment control device 10 drives the opening and closing shutter drive unit 9d of storage container openings according to the detected value of air themperature checkout gear 4, air humidity detection device 5 and lid temperature-detecting device 6, will in the first storage container 1, be controlled at the humidity range (not in the inner surface dewfall of storage container inner cap 33 and can suppress the best humidity range of the transpiration rate of vegetables load) of expectation.,, in present embodiment 7, humidity environment control device 10 is equivalent to the humidity conditioner in the utility model.And the opening and closing shutter drive unit 9d of storage container openings and storage container openings opening and closing shutter 40 are equivalent to the aperture portion opening and closing device in the utility model.And storage container openings 39 is equivalent to the first container through hole in the utility model.In addition, the opening and closing shutter drive unit 9d of storage container openings opening and closing shutter 40 and storage container openings is arranged at the bottom surface in the first storage container 1 in Figure 20, if but be positioned at the first storage container 1 and boundary face the second storage container 2, for example also can be arranged on side in the first storage container 1, also can be arranged on the outside of the first storage container 1.
Secondly, use Figure 20 to describe an example of action.About action, for the position identical with embodiment 6, description thereof is omitted.
The first storage container 1 is formed as air-tight state or semi-hermetic state by the first storage container cap 1a and storage container inner cap 33, therefore maintains high humility, and the transpiration of vegetables is suppressed.But, in the time that the humidity in the first storage container 1 is too high, exists and be created in the interior generation dewfall of the first storage container 1, because dew causes vegetables load 402 to rot and causes the possibility of the problem such as mouldy because of the dew being detained.
Now, for the related vegetable compartment container 401 of present embodiment 7, as shown in figure 20, the first storage container 1 and the second storage container 2 between boundary face be formed with the storage container openings 39 that connects the first storage container 1 and the second storage container 2, therefore, can make highly humid air flow into leak tightness and low the second storage container 2 inside of humidity ratio the first storage container 1, can make highly humid air circulate in the lower container of humidity., same with embodiment 1, detect the air themperature in the first storage container 1, the inner surface temperature of air humidity and storage container inner cap 33, to make inner surface temperature higher than the dew-point temperature calculating according to air themperature and air humidity, and air humidity enters the mode of the high humility scope of regulation, storage container openings 40 is opened and closed, control the internal circulating load from storage container openings 39 towards the second storage container 2, i.e. air humidity in the first storage container 1, thus, with the kind of loading according to the vegetables that take care of in inside, the difference of amount and different transpiration rate is irrelevant, can be in the inner surface dewfall of storage container inner cap 33, and can suppress the transpiration of vegetables load.And, because the highly humid air in the first storage container 1 is directly supplied to the second storage container 2, therefore, even if also can guarantee to suppress to a certain extent the rising humidity of vegetables in the second storage container 2.
In addition, in Figure 20, only at interior air themperature checkout gear 4, air humidity detection device 5, the lid temperature-detecting device 6 of arranging of the first storage container 1, according to the percent opening of the inner surface temperature control storage container openings 39 of the air themperature in the first storage container 1, air humidity and storage container inner cap 33, but, also can detect the inner surface temperature of air themperature in the second storage container 2, air humidity, storage container inner cap 33, consider that in the lump the state in the second storage container 2 controls the percent opening of storage container openings 39.Now, for example only in the second storage container 2, become in the situation of higher load condition, the percent opening that can increase storage container openings 39 makes the highly humid air in the second storage container 2 keep out of the way in the first storage container 1, the control of the dewfall in inhibition the second storage container 2 etc.And, finally can make the air humidity in the second storage container 2 rise to and the interior identical degree of the first storage container 1, therefore, in the second storage container 2, also can guarantee to suppress the rising humidity of vegetables.
And, in Figure 20, to be disposed at the second storage container 2 above first storage container 1 of (or inner) example that the opening and closing shutter drive unit 9d of storage container openings 39, storage container openings opening and closing shutter 40 and storage container openings is set be illustrated, but the configuration relation of the first storage container 1 and the second storage container 2 is not limited to the structure of Figure 20.The opening and closing shutter drive unit 9d of storage container openings 39, storage container openings opening and closing shutter 40 and storage container openings for example, also can for example, be set at the vegetable compartment container 401 (structure shown in Figure 16 of embodiment 1～5, embodiment 6) that the second storage container 2 is disposed to the side of the first storage container 1., as long as form storage container openings 39 in the mode of the mutual opposed sidewall that connects the first storage container 1 and the second storage container 2.
And, in Fig. 2, only control the humidity in the first storage container 1 by the percent opening of storage container openings 39, but, when being formed with the air adiabatic layer 36 of having narrated in embodiment 6, also can the lid aperture portion 7a of the first storage container and the lid aperture portion 7b of the second storage container be set at storage container inner cap 33, or the lid aperture portion 7c of air adiabatic layer is set at the first storage container cap 1a, combine the percent opening of above-mentioned each aperture portion and control.Although only also can control by the balance of the air humidity in the first storage container 1 and in the second storage container 2 by the percent opening of storage container openings 39, but the situation that becomes overload state when one party is inferior, make highly humid air in the interior circulation of air adiabatic layer 36 by the lid aperture portion 7b of the lid aperture portion 7a via the first storage container and the second storage container, the lid aperture portion 7c of air adiabatic layer, and towards vegetable compartment 400 exhausts, can avoid reliably the inner surface dewfall at the first storage container cap 1a.
