In the refrigerator carrying out forced circulation of cold air cooled by a cooler (9) to the freezing chamber (3) by using a blowing means such as a cold air circulation fan (10), an absorbing and releasing material (13) having moisture absorbing power even in a place with low relative humidity is provided in the freezing chamber (3).
Description
Technical field
The present invention relates to deep freezer.
Background technology
In the refrigerating chamber of the deep freezer of on market, selling (3.0～5.0 ℃ of room temperatures), the vegetable compartment (3.0～6.0 ℃ of room temperatures), because of draw the purpose that humidity worsens with the outward appearance that prevents contents and taste from contents, and in each chamber, possesses when the high humility of this chamber moisture absorption and moisture adsorption and releasing parts (for example, opening the 2001-91145 communique) that the moisture that stores will be in high humility when becoming low humidity the time is emitted with reference to patent documentation 1-spy.
Existing deep freezer does not contemplate fully to remaining high humility in the refrigerating chamber that holds meat and fish etc.
That is, be contained in food such as meat in the refrigerating chamber and fish, when buying in the supermarket etc., must be by commerce with preservative film (polyvinyl chloride system preservative film) parcel.And, since freezing, reduce and dry situation so be sure of can not occur moisture.Therefore, owing to be contained in the refrigerating chamber (chambers below 18 ℃) of deep freezer, and by preservative film (polyvinyl chloride system preservative film) parcel, so be not contemplated to the situation that freezing moisture is emitted from flesh of fish distillation fully.
Its result because long preservation (for example more than 15 days) flesh of fish waits food in refrigerating chamber, so exist the corner of the flesh of fish to bleach, eat after thawing mouthfeel bad (following with this phenomenon be called freezing excessively), cause being discontented with of user.
As mentioned above, be owing to commercial moisture is seen through as can be known with preservative film, thus if food such as the long-time freezing preservation flesh of fish, then the moisture that food had such as this flesh of fish would also move on to outside the refrigerating chamber because of the cold air in freezing indoor circulation by preservative film.
Have, the suction of adopting is usually all the time emitted Type B silica gel is arranged in the material again.But, have effectively though this Type B silica gel is put in refrigerating chamber and vegetable compartment and so on than the chamber of juicy food, be set in room temperature can not get same effect under the situation in the refrigerating chamber below-18 ℃.Therefore, can not be diverted in the refrigerating chamber.In other words, have at the low local moisture absorption rate variance of relative humidity, in the high place of relative humidity (refrigerating chamber or the refrigerating chamber) characteristic that hydroscopicity is high, so can not be diverted to the low refrigerating chamber of relative humidity owing to Type B silica gel.
In addition because frozen food (flesh of fish) is with preservative film parcel and be contained in the refrigerating chamber, so one side of manufacturer less than the understanding of not emitting moisture by this preservative film, thereby the conception itself that the humidity of refrigerating chamber remains high humidity is not existed yet.
Summary of the invention
Even the purpose of this invention is to provide in room temperature and also can suppress the deep freezer that the moisture of food is emitted by preservative film in for the refrigerating chamber below-18 ℃.
The present invention for achieving the above object, has the freezing refrigerating chamber that holds contents, can open and close the drawer door of this refrigerating chamber, the container of coming in and going out with the switching of above-mentioned drawer door, outlet with the rear wall of being located at above-mentioned refrigerating chamber, to discharge from above-mentioned outlet with the circulating cold air fan by the cold air of cooler cooling, forced circulation is in the refrigerator of above-mentioned refrigerating chamber, it is characterized in that: above-mentioned outlet also is located at the top than the rear wall top of said vesse, even also keep the suction of moisture absorption to emit the inboard that material is located at the rear wall of said vesse in the state that the relative humidity that cold air arranged in above-mentioned freezing indoor circulation is low.It is that to be easy to ionization be that material is emitted in the suction that the crosslinked body of Sodium Polyacrylate with carboxylic acid sodium base of cation and anion is constituted that material is emitted in suction.
According to the present invention, also can suppress the deep freezer that the moisture of food is emitted by preservative film in for the refrigerating chamber below-18 ℃ even provide in room temperature.

At first, with Fig. 1～Fig. 4 the deep freezer of present embodiment is described.Fig. 1 omits the door of deep freezer of present embodiment and the front view of expression.Fig. 2 is a H-H line cutaway view among Fig. 1.Fig. 3 is the stereogram that partition component compiles product.Fig. 4 is that the expression partition component compiles the inboard stereogram of product.
And, will be expressed as being divided into the formation of ice-making compartment 3a, quick freeze chamber 3b and refrigerating chamber 3c as the refrigerating chamber 3 of refrigerating chamber 3 expressions.Possess automatic ice-making plant and ice container in ice-making compartment 3a, ice container becomes the structure that together is drawn out with door by drawer type door is pulled out.In addition, quick freeze chamber 3b and refrigerating chamber 3c also seal whole peristome by each drawer type door, and become by pulling out chamber door and pull out the formation of internal container.
Especially, refrigerating chamber 3c holds three containers as shown in the figure up and down, begins to be provided with respectively lower floor's refrigerating chamber container 5, middle level refrigerating chamber container 6, upper strata refrigerating chamber container 7 from lower floor.Though not shown, lower floor's refrigerating chamber container 5 and middle level refrigerating chamber container 6 are fixed in pulling out on the frame of refrigerating chamber door, and come in and go out in the refrigerating chamber 3c with the switch gearing ground of this refrigerating chamber door.The structure of upside refrigerating chamber 7 can be pulled out with respect to refrigerating chamber 3c for utilize the guide rail that is provided with on the inner box side face that constitutes refrigerating chamber 3c sidewall.
Therefore, when pulling out refrigerating chamber door, pull out lower floor's refrigerating chamber container 5 and middle level refrigerating chamber container 6.Upper strata refrigerating chamber container 7 can be pulled out container 7 along the guide rail of refrigerating chamber 3c sidewall under the state of pulling out door, and can pack into and take out food.These each containers the 5,6, the 7th, the mutually different container of depth dimensions is suitable for holding the various food that vary in size.
Then, in Fig. 2, the cold air that the cooler chamber 8 that the back of using by refrigerating chamber 3 is formed produces cools off refrigerating chamber 3 interior these points and describes.
Be provided with cooler chamber 8 at the back of refrigerating chamber 3.Disposed the cooler 9 that constitutes freeze cycle in the cooler chamber 8.As the wind pushing mechanism that is used for the cold air that forms at this cooler 9 is delivered to refrigerating chamber 3, circulating cold air fan 10 is disposed at the top of cooler 9.The cold air that circulating cold air fan 10 will generate in cooler 9 is delivered to refrigerating chamber 3, and makes the cold air forced circulation.
The cold air that generates in cooler 9 is delivered to refrigerating chamber 2 and vegetable compartment 4 by circulating cold air fan 10, and the so-called circulating cold air of behind these each chambers of cooling, getting back to the cooler chamber, in the cold air path that arrives refrigerating chamber 2 and vegetable compartment 4, valve 11 is set, to carry out the switch of cold air path.
Between refrigerating chamber 3 and cooler chamber 8, separate by partition component.The partition component that mark 12 expression contains this partition component and is assembled with other parts in advance compiles product.Partition component compiles on the product 12 outlet (with reference to Fig. 3) that each refrigerating chamber container 5～7 conveying cold air that ground, corresponding each position is provided with three layers of configuration are up and down used.
In addition, as shown in Figure 4, compile the space that configuration cooler 9 has been guaranteed in product 12 inboards at partition component, and assembled circulating cold air fan 10 and valve 11 in advance.
As shown in Figure 2, suction has been installed and has emitted material 13 in lower floor's refrigerating chamber container 5.Though the suction of present embodiment is emitted material 13 and do not select the infield under equivalent environment,, as effective installation site, can enumerate for example as upper/lower positions.
For example, by being installed on the refrigerating chamber container of together pulling out, increased the chance of contact extraneous air with drawer door.In addition, also effective in the position that discharge cold air can not directly blow to.So, on lower floor's refrigerating chamber container 5, installed to suck and emitted material 13.Therefore, lower floor's refrigerated container 5 is pulled out to outside the refrigerating chamber 3, and can from outdoor air, draws moisture along with door switch.
In addition, in the present embodiment, suck in the rear wall installed inside of lower floor's refrigerating chamber container 5 and to emit parts 13, and be located on the position that the cold air that is discharged in the refrigerating chamber 3 can not directly blow to.Especially, lower floor's refrigerating chamber container 5 of present embodiment possesses rake in the rear end, bottom surface of middle level refrigerating chamber container 6 so that opening above the rear wall, so the suction of the rear wall inboard of refrigerating chamber container 5 is emitted material 13 tops and also opened, realized sucking the raising of emitting efficient.
Then, use Fig. 5～Figure 11 come to the suction of present embodiment emit material 14 specification (characteristic), suck the effect of emitting material 14 and effect etc. and describe.When each figure is carried out simple declaration, Fig. 5 is that the figure of material behavior is emitted in the suction of expression present embodiment, (a) being dry silk (5-1) and the length of temperature adjustment silk (5-2) and the figure of diameter of actual measurement tacryl, (b) is expression with the figure of drying thread and the temperature adjustment silk weight slip when room temperature rises to 200 ℃.Fig. 6 is explanation keeps the principle of water in material is emitted in suction figure.Fig. 7 is that expression sucks the figure that concerns between the relative humidity emit material and the hydroscopicity.Fig. 8 is that expression sucks the figure that concerns between the moisture absorption emit material and the moisture releasing.
Fig. 9 is the figure of expression preservative film material with respect to the moisture vapor permeability of temperature, key diagram when Figure 10 is the saturated vapor amount of guaranteeing in the refrigerating chamber, Figure 11 be illustrated in when possessing the section beef that sucks accommodating belt packing in the refrigerating chamber of emitting material water evaporation quantity and with the ham of the preservative film parcel of polyvinyl chloride system with cut vegetables and the figure of water evaporation quantity when being contained in the refrigerating chamber.
At first, Fig. 5～Fig. 8 is described.The suction of present embodiment is emitted material 13 and is made of the tacryl 14 of chemical treatment.The tacryl 14 of this chemical treatment has constituted the crosslinked body of Sodium Polyacrylate.
The crosslinked body of this Sodium Polyacrylate carries out the moisture absorption of water by main points shown in Figure 6.That is, has the ionization of being easy to and is the carboxylic acid sodium base of cation and anion (COONa), if contact water is then received water-soluble as shown in Figure 6 and expanded with mesh configuration.If enter water in the mesh configuration of this expansion, the carboxylic acid sodium base (sodium ion (Na COONa) then
+) ionization, the residual carboxyl (COO that has as its residue in the strand
-).Because this carboxyl (COO
-) be anion, so electricity is repelled each other mutually, mesh configuration is further expanded.Enter in the mesh configuration of this expansion and kept a large amount of water.
Then, the specification (characteristic) to the tacryl of chemical treatment describes.In Fig. 5 (a), when tacryl after dry chemistry is handled is measured in expression (hereinafter referred to as dry silk) and be positioned over 20 ℃, the fibre length in 90%RH environment following time and the result of fibre diameter size.Its result is because length and fibre diameter become big, so carried out the moisture absorption of water as can be known with above-mentioned main points.
Have again, the result who investigates the water content of this drying silk and damping silk is represented in Fig. 5 (b).5-1 represents dry silk, and 5-2 represents the damping silk.This result gradually brings up to the 200 ℃ results that also measure this moment weight rate with temperature from room temperature with 10 ℃/minute speed with dry silk and each 10g of damping silk.Its result, the weight rate when weight is made as 100% with the initial stage is, and dry silk is 18.1%, and the damping silk is 32.8%.That is, the tacryl after the above-mentioned as can be known chemical treatment of this result absorbs moisture.
Use by the non-weaving cloth of this type of tacryl is emitted material as suction, but the indoor food of freezing-inhibiting is freezing excessive.
Even Fig. 7 confirm to suck to emit material also presents high moisture absorption when low humidity figure, 7-1 represents that tacryl is carried out the suction that the crosslinked body of Sodium Polyacrylate after the chemical treatment constituted emits material, and 7-2 represents Type B silica gel, and 7-3 represents A type silica gel.
From this Fig. 7 as can be known, even because material 7-1 is emitted in the suction of present embodiment and Type B silica gel 7-2, A type silica gel 7-3 have relatively also given play to high moisture absorption under low humidity, so even also can give play to its function fully at low-moisture refrigerating chamber as can be known.
Fig. 8 confirms to suck to emit material 13 sucks the situation of emitting when high humidity, low humidity result of the test.As shown in Figure 8, arrive hydroscopicities 60% for for example continuing moisture absorption at 90% o'clock so that material 13 is emitted in suction, arrive about 30% for for example continuing moisture releasing at 45% o'clock up to hydroscopicity in humidity (RH) in humidity (RH).
Therefore, if use it for the refrigerating chamber of deep freezer, suck when then the humidity in deep freezer running and refrigerating chamber descends and emit material 13 and continue to emit, and when the running of deep freezer stops, carrying out moisture absorption.
And, the moisture supply that material 13 is emitted in this suction during by door switch in the outdoor air Defrost water evaporating the when dew of moisture or defrosting and the moisture of getting back in the refrigerating chamber carry out.
Then, use Fig. 9～Figure 12 to come to describe to the suction of present embodiment being emitted the effect of material 13 when being used for deep freezer.
Fig. 9 is the figure of the moisture vapor permeability of the preservative film of expression when fish superscribed preservative film and be arranged in the refrigerating chamber.As the preservative film material, with Vingon system preservative film, polyvinyl chloride system preservative film, polyethylene system preservative film product as a comparison.
Polyvinyl chloride system preservative film such as is used in the supermarket at the parcel flesh of fish.Situation about at once not eating etc. buying the meat fish of having used this preservative film packing sale, these oppress most freezing preservation.At this moment, suppose preservative film parcel the packing former state be contained in the refrigerating chamber.
As shown in Figure 9, the preservative film material of normally used meat fish (polyvinyl chloride system preservative film) compares with other preservative film material, even under 38 ℃, 90%RH, 24 hours environment, and under hypothesis-18 ℃ in the refrigerating chamber, 65%RH, 15 days environment, it is very high that the moisture vapor permeability also becomes.
In other words, when the meat fish with polyvinyl chloride prepared material parcel was contained in the refrigerating chamber for a long time, expression was through the preservative film material and by the moisture in the absorption of the cold air in the refrigerating chamber meat fish.
It is known that to capture moisture by this moisture absorption be fish, meat matter are descended and to cause one of so-called freezing excessive reason.Therefore, the freshness of refrigerating chamber interior damping becoming food keeps necessary.
Even the present invention emits material and it is installed in the refrigerating chamber by the suction that exploitation also can moisture absorption under low humidity, and the quality that can prevent the meat fish of refrigerating chamber in preserving descend (freezing excessively).
Then, use Figure 10 to come to prevent that to being used to freezing excessive mechanism from describing.
In Figure 10, represent to be used to make to be the ideograph of water vapour amount 0.12g/ platform in the refrigerating chamber with 100L deep freezer.That is, every water vapour amount with deep freezer of 100L refrigerating chamber is 0.12g.
As shown in figure 10, preestablish to suck and emit the capacity of material 13, so that come from the amount of moisture of food (water) and come from that to suck the amount of moisture of emitting material 13 be 7: 3 ratio.Its main cause is, emit material 13 self price height owing to suck, though so be not unrestrictedly to increase, if have jumbo suction and emit material 13 but put in advance, then when being contained in food in the refrigerating chamber, carry out moisture absorption on the contrary earlier, thereby avoid capturing the problem of moisture from frozen food.
Therefore, in the present embodiment, possessing the ratio of emitting moisture is 7: 3, and material is emitted in the suction of at least 6: 4～8: 2 scopes, and the indoor food of freezing-inhibiting is freezing excessive.
The moisture supply of emitting material 13 to this suction is as stating, and that the refrigerating chamber container is exposed to is outdoor by pulling out refrigerating chamber door, and the condensate water that produces when material 13 contact outdoor airs are emitted in suction or make in the refrigerating chamber during in defrosting is carried out in the high humilityization.
In addition, should should be mentioned that especially that the refrigerating chamber humidity (RH) in the deep freezer running is about 30% not using suction to emit under the state of material 13, the humidity during the deep freezer running stops is about 60%.In refrigerating chamber, judge as humidity so big variation take place that this becomes one of freezing excessive reason as can be known.
Have, the reason that humidity changes is as follows again.When freeze cycle turns round, make circulating cold air by circulating cold air fan 10.Under the state of circulating cold air, the moisture frosting of cold air of getting back to cooler chamber 8 from refrigerating chamber 3 is on cooler 9, and the moisture in the refrigerating chamber is captured gradually.As a result, the humidity in the refrigerating chamber will descend in the deep freezer running.
About the variation of this humidity, with how much having little or nothing to do with of the frozen food that is held.Its reason is, except that refrigerating chamber is maintained typical temperature-18 ℃ relation, compare with other storerooms such as the refrigerating chamber of refrigerated storage temperature band and vegetable compartment, can enumerate make excessive circulating cold air and in refrigerating chamber during food freezing the rate of sublimation of frozen moisture fall behind.
In the present embodiment, emit material 13, the part of the moisture before captured from food to be emitted material 13 burdens by this suction, and realize suppressing food drying by in refrigerating chamber, possessing to suck.
Then describe emitting the effect of material 13 when being located in the refrigerating chamber based on the suction of above-mentioned characteristic and specification.
Figure 11 is that expression has or not and sucks the different figure from the water evaporation quantity of food emit that material 13 produced, be specially, be illustrated in that the suction that can suck 2～4 one-tenth water vapours of emitting refrigerating chamber saturated vapor amount emits that material 13 is installed in the refrigerating chamber and the beef band packing ground of will cut into slices when not being installed in the refrigerating chamber when holding water evaporation quantity and with ham with the preservative film with polyvinyl chloride system of having cut vegetables wraps up and the water evaporation quantity when being contained in the refrigerating chamber.From this figure as can be known, to suck under the situation of emitting material be 0.35g when the water evaporation quantity when section beef band packing ground is held is preserved 15 days in refrigerating chamber and having, relatively, be 0.91g not having to suck under the situation of emitting material, about 2.6 times of the water conservation effect of food.
In addition, as can be known, the ham class of having cut into slices is easily dry than approaching food, and the water evaporation quantity that sees through preservative film when preserving 15 days in refrigerating chamber is 0.10g there being suction to emit under the situation of material, not having to suck under the situation of emitting material is 0.37g, about 3.7 times of the water conservation effect of food.Do not have these suctions to emit can to confirm under the situation of material to have taken place previously described freezing excessively, also can confirm to have having to suck and difficultly under the situation of emitting material freezing excessive effect occurs.
In addition, as can be known, as the situation of the food that once all held as having cut vegetables under, when in refrigerating chamber, preserving 15 days, the water evaporation quantity that sees through preservative film is 0.27g there being suction to emit under the situation of material, relatively, be 0.51g not having to suck under the situation of emitting material, about 1.9 times of the water conservation effect of food.The water conservation effect be not as obviously can thinking as above-mentioned two kinds of foods, because the group food that cut vegetables once all is received, so compare the difficult evaporation of moisture with thin food such as ham.In the example that has cut vegetables, when having or not suction to emit material, can not confirm freezing excessive significant difference.Yet, though, also can know and confirm the water conservation effect less than the effect of above-mentioned beef and ham.
According to above-mentioned, emit material 13 so long as under the environment below-18 ℃, also can suck the suction of 2～4 one-tenth water vapours of emitting refrigerating chamber saturated vapor amount and emit material and get final product even can confirm to suck, simultaneously, the quality effect of food also can improve its 2～4 one-tenth as can be known.
As mentioned above, present embodiment, make having wind pushing mechanism such as circulating cold air fan in the refrigerator of cold air forced circulation in refrigerating chamber of cooler cooling, even be arranged in the refrigerating chamber, so even can be suppressed at distinctive freezing excessive problem in the refrigerating chamber that the flesh of fish of placing in the refrigerating chamber bleaches and the edible also mouthfeel in the back that thaws is bad owing to will when relative humidity is low, also can keep the suction of moisture absorption to emit material 13.
In addition, emit material 13 as suction, use to have the Sodium Polyacrylate crosslinked body of easily ionizable as the carboxylic acid sodium base of cation and anion, so even under low humidity, also can bring into play high moisture absorption, and can remain the humidity higher with easily becoming low-moisture refrigerating chamber than existing deep freezer.
Have again, emit material 13 as suction, use has the suction of the capacity that sucks 2～4 one-tenth water vapours of emitting refrigerating chamber saturated vapor amount and emits material, so suction is emitted material 13 and not only can significantly do not drawn freezing indoor moisture, also can with moisture that comes from frozen food etc. etc. together efficient keep freezing indoor humidity well, with the drying of effective freezing-inhibiting food.
In addition, suck and to emit material 13 and when the circulating cold air fan running, emit water vapour, do not emit material, thereby favourable on price so can not increase in vain to suck, but and efficient keep the space that is provided with in the refrigerating chamber well.
Also have, suction is emitted material and is installed on draws water vapour on the refrigerating chamber container of installing and when door switch on drawer door from outdoor air, so the part of the moisture of emitting from refrigerating chamber in the running of deep freezer is the food supply in the refrigerating chamber not, and can supply from outdoor air, thereby also can be when refrigerating chamber is low humidity with remaining high humility in refrigerating chamber from the moisture of outdoor absorption.
