Abstract

To provide a refrigerator capable of restraining moisture of frozen food from sublimating with a simple structure, while optimally freezing and preserving the frozen food. A quick cold accumulating plate 30 is installed in an opening part 16a of a storage vessel 16 stored in a freezing room, and cuts off a substantially half of the innermost part of the opening part 16a. This quick cold accumulating plate 30 is formed of aluminum, and can substantially uniformly cool the frozen food in the storage vessel 16 so that a temperature difference between the frozen food and a storage bag does not become large, by weakening force of cold air blown to the storage vessel 16 by once receiving the cold air blown to the storage vessel 16, to thereby prevent a continuance of sublimation of the moisture from the frozen food due to being large in the temperature difference between the frozen food and the storage bag, and the deterioration in an eating feeling can be prevented by preventing a drying-up feeling when cooking the frozen food.

Description

Refrigerator

Technical field

The present invention relates to have the refrigerator of the refrigerating chamber that reduces the freeze-dried property of frozen food.

Background technology

Upward-acting door formula chilled storage refrigerator as an example except that enclosing cover, also has the inner cap of being made by foamed styrene etc.This inner cap is mainly used in the low-temperature refrigerator, escapes by the cold air that suppresses in the refrigerator, has slowed down temperature rising in the refrigerator, thereby has saved energy.

In addition, be used for controlling the invention that temperature in the refrigerator rises as this, also oriented patent document 1 is such, outside interior surface (on the inner cap) and preserve the scheme that cool storage material is set on the refrigerator inwall.

Patent document 1 refers to that the spy opens flat 9-303931 communique.

In addition, in the refrigerator of family expenses, have refrigerating chamber, vegetable compartment that is in the refrigerated storage temperature district and the refrigerating chamber that is in the cryogenic temperature district etc., usually, in refrigerating chamber, because chilling temperature is low more, the storage life of frozen food is just long more, and therefore the upper rear portion at accommodating container is provided with the cold air blowing mouth, and the cold air about-30 ℃ is directly blown in the accommodating container.(example is a patent document 2).

Patent document 2 refers to that the spy opens the 2004-69253 communique.

Yet under the situations as inner cap such as use foamed styrene, the setting of lid is to prevent the cold air escape, if but the temperature in the refrigerator risen, because the thermal insulation of lid also makes the temperature in the refrigerator be difficult to descend, therefore this is not an optimum structure for food preservation.

In addition, for the device that cool storage material is set on inner cap top and inwall, the effect of cool storage material is to improve the stability of temperature in the refrigerator, but owing to used cool storage material, the whole change of equipment is weighed, and problems such as volume reducing occurred receiving in the refrigerator.

In addition, for being contained in the indoor storage container of refrigerator refrigeration, because both the foamed styrene inner cap not being set is not provided with cool storage material yet, and the very low cold air of the temperature of coming flash-pot (for example-30 ℃) directly blows on the food, therefore a lot of moisture evaporations in the food have been made, when eating with the such frozen food cooking, food is wizened, and mouthfeel is bad.

And in existing freezer compartment structure, be in the container that holds frozen food, directly to blow a cold wind over, the sack of dress food is cooled off rapidly, because the temperature difference of sack and food increases, and causes the moisture evaporation in the food, with the form of frost inner surface attached to bag, just form so-called freeze drying phenomenon, because more moisture evaporation falls in the frozen food of packed grade, on the inner peripheral surface of bag, form frost, particularly in the surface and the bight of frozen food dry problem appears therefore.After above-mentioned frozen food appearance was freeze-dried, when eating with this frozen food cooking, food was dry, and mouthfeel is bad.For preventing above-mentioned freeze-dried phenomenon, can adopt the indirect type of cooling in the vegetable compartment cooling, because refrigerating chamber must be cooled to the low temperature below-18 ℃, therefore only take so indirect cooling, just can not make cooling food be cooled to the cryogenic temperature district, so probably can not carry out freezing preservation.

Summary of the invention

The present invention lay particular emphasis on above some and design, its objective is provides a kind of refrigerator, it can make frozen food most suitably be preserved, and uses simple structure, just can prevent that frozen food from making its drying because of moisture evaporation.

In addition, the present invention designs for overcoming existing defective, and its objective is provides a kind of refrigerator, and it can make frozen food most suitably be preserved, and simultaneously, utilizes simple structure can prevent the volatilization of moisture in the frozen food.

The invention provides a kind of refrigerator, it has and is contained in cold air in the freezing zone, that come flash-pot and delivers to its inner case shape storage container from upper shed, it is characterized in that: have be installed on the above-mentioned storage container, under its confined state, can interdict the cold air that comes flash-pot and directly send non-seal lid cold wind, that have thermal conductivity to inside from the peristome of above-mentioned storage container.

Further, for addressing the above problem, the invention provides a kind of refrigerator, it has the cold air that blows out from the cold air mouth that is located at back side top and is cooled to the refrigerating chamber in cryogenic temperature district, with the accommodating container that is located at the top opening in this refrigerating chamber, it is characterized in that, with this accommodating container, be that top opening facing to the rear of above-mentioned cold air mouth is closed with lid at least.

If employing the present invention, be placed on the frozen food in the storage container because non-seal lid exists and can not be come the cold air of flash-pot directly to blow to, therefore lid is significantly blown the intensity of cold air with weakening, thereby makes the temperature in the storage container even substantially.In this case, lid is owing to have thermal conductivity, so the radiation of lid can also make storage container efficiently be cooled off.

The result of equalizing temperature in this storage container makes to diminish with the frozen food of packaging bags and the temperature difference between the packaging bag, owing to eliminated the water transport that causes because of the temperature difference, has therefore suppressed the volatilization of moisture in the frozen food.Like this, prevented drying property and the mouthfeel bad problem of frozen food when the cooking.

Further, if adopt foregoing invention, for the frozen food that is placed in the accommodating container, because lid, cold air can not directly be given the frozen food in the accommodating container, and the sack etc. that has therefore prevented to hold frozen food is cooled off rapidly.Like this, the temperature difference between frozen food and the sack etc. diminishes, owing to suppressed to be moved by the moisture that the above-mentioned temperature difference causes, has therefore prevented the volatilization and the food drying of moisture in the frozen food.

In refrigerating chamber 6A, can hold the storage container 16A that links to each other with refrigerating chamber door 10A inner surface with coming in and going out.

In addition, as shown in Figure 2, portion is arranging freezing cycle device 17A at the back side of refrigerator body 1A.That is to say, form the refrigerating chamber 18A of evaporator room (hereinafter referred to as R evaporator room) at the back side of vegetable compartment 4A, in the 18A of R evaporator room, use the evaporimeter 19A (hereinafter referred to as the R evaporimeter) except that being furnished with the refrigerating chamber that constitutes freezing cycle device 17A, also arranging the refrigerating chamber blowing fan 20A (hereinafter referred to as R chamber fan) of variable speed drive (for example 1800-2400rpm) at an upper portion thereof.When R chamber fan 20A was in negative load condition, the cold air by R evaporimeter 19A generates behind supply refrigerating chamber 3A and the vegetable compartment 4A, turned back to the bottom of the 18A of R evaporator room again, finishes circulation thus.In addition, in the 18A of R evaporator room, also be provided with R evaporimeter Defrost heater 21A.

In addition, cross over ground up and down and switch chamber 5A and not shown ice making the back side and form refrigerating chamber with the 22A of evaporator room (hereinafter referred to as F evaporator room) with refrigerating chamber refrigerating chamber 6A arranged side by side, in the 22A of F evaporator room, use the evaporimeter 23A (hereinafter referred to as the F evaporimeter) except that being furnished with the refrigerating chamber that constitutes freezing cycle device 17A, also arranging the refrigerating chamber blowing fan 24A (hereinafter referred to as F chamber fan) of variable speed drive (for example 1800-2400rpm) at an upper portion thereof.In addition, below F evaporimeter 23A, also be provided with F evaporimeter Defrost heater 25A.

Among the present invention, be located at the downstream (cold air blows out side) of the F chamber fan 24A in the 22A of F evaporator room, branch into the cold air runner that is used to switch the cold air runner of chamber 5A and is used for refrigerating chamber 6A, wherein, switch in the cold air runner of chamber 5A being used to, the switching chamber air door 26A that is carried out switch control by not shown control device is being set.

Be closed condition when switching the chamber with air door 26A, fan 24A driven occasion in F chamber by the cold air that F evaporimeter 23A generates, behind supply refrigerating chamber 6A and the not shown ice making refrigerating chamber, turns back to the bottom of the 22A of F evaporator room again, finishes circulation thus.On the contrary, open (or partially opening) with air door 26A, the driven occasion of F chamber fan 24A when switching the chamber, cold air is except that supplying with refrigerating chamber 6A and ice making with the refrigerating chamber, also to after supplying with switching chamber 5A, turn back to the bottom of the 22A of F evaporator room again, finish circulation thus.

Form Machine Room 27A at the back side, bottom of refrigerator body 1A, in the 27A of Machine Room, except that the compressor 28A that constitutes freezing cycle device 17A is set, also is being provided with and is being used for the cooling fan 29A of cooling compressor 28A and not shown condenser.Compressor 28A, by converter Control, can variable speed drives (for example, the running frequency number of transverter is 30-70Hz, and in addition, cooling fan 29A also can be by variable speed drives (for example 1800-2000rpm).

Next, among Fig. 1 of storage container 16A stereoscopic display in will being contained in refrigerating chamber 6A, the 30A of hold-over plate rapidly (being equivalent to lid) that the present invention relates to is installed on the peristome 16Aa of storage container 16A, and hold-over plate 30A covers the only about half of part of the length of storage container 16A peristome 16Aa depth direction rapidly.This is hold-over plate 30A rapidly, be that aluminium sheet 32A with 0.8mm is set to resin system framework 31A integratedly and goes up and form, it is installed on the rail portion 33A that is located at storage container 16A peristome 16Aa, just can slide from closed position shown in Figure 1 to the open position that moves towards depth direction shown in Figure 3, and when open position, also can pass through not shown retainer, make it stop to slide.In this case, when as Fig. 5, when the storage container 16A that allows hold-over plate 30A rapidly be in the release position returned refrigerating chamber 6A, hold-over plate 30A was by withstanding the rear wall of refrigerating chamber 6A rapidly, and slides into the closed position from the release position.Therefore, during state in storage container 16A is in refrigerating chamber 6A, hold-over plate 30A is on the rear position of storage container 16A peristome 16Aa of the cold air blocking that will deliver to storage container 16A from F evaporimeter 23A rapidly.

Effect to said structure describes below.

When accommodating food in refrigerating chamber 6A, as shown in Figure 4,10A draws back with refrigerating chamber door, 16A pulls out with storage container, resembles shown in Figure 5ly as required, and making rapidly, hold-over plate 30A slides into the rear, after being placed into food in the storage container 16A, storage container 16A is recovered among the refrigerating chamber 6A.Like this, because the only about half of part at the peristome 16Aa rear of storage container 16A is by hold-over plate 30A covering rapidly, after hold-over plate 30A blocks rapidly from the next Quilt with air conditioning of F evaporimeter 23A, flow in the storage container 16A, make the food freezing preservation among the storage container 16A thus by the long period.

Yet,, just have mouthfeel preferably when edible, otherwise have food because of the bad problem of moisture evaporation mouthfeel if frozen food can be cooked under maintenance food water frozen state.

Phenomenon below the former reason of frozen food moisture evaporation is explained.Promptly shown in Fig. 6 (a), frozen food 34A is being packed by packaging bag 35A usually, is preserving under the state of refrigerating chamber 6A, and packaging bag 35A is exposed to from the cold air that F evaporimeter 23A comes, and makes the temperature of packaging bag 35A become lower.Just, when the target temperature of refrigerating chamber 6A is-18 ℃, when cold air temperature became-30 ℃, with respect to-18 ℃ food temperature, the temperature of its packaging bag 35A was-30 ℃.Like this, the temperature of packaging bag 35A is just much lower than the temperature of frozen food 34A, and the moisture that volatilizees from frozen food 34A is as the inner surface (with reference to Fig. 6 (a)) of frost attached to packaging bag 35A.In this case, owing to all be frost attached on the packaging bag 35A inner surface from the moisture of food 34A volatilization, saturated vapor density in the packaging bag 35A is risen, so just make the moisture among the food 34A continue volatilization, simultaneously, the moisture of volatilization is constantly on the inner surface of form attached to packaging bag 35A with frost.The existence of above-mentioned phenomenon causes frozen food 34A moisture to move to the inboard of packaging bag 35A, makes that a lot of moisture among the frozen food 34A are volatilized to be fallen.

In addition, when passing through Defrost operation, the temperature of refrigerating chamber 6A rises, and when the temperature that makes frozen food 34A is lower than the temperature of air in the packaging bag 35A, volatilizees attached to the frost in the packaging bag 35A, at this moment, go up (with reference to Fig. 6 (b)) although form frost attached to frozen food 34A, when sending cold wind, when the temperature that makes packaging bag 35A is lower than the temperature of frozen food 34A once more, volatilize again attached to the lip-deep frost of frozen food 34A, and attached to the inboard of packaging bag 35A.

Because above-mentioned repetitive operation, more moisture has moved to the inboard of packaging bag 35A among the frozen food 34A.Like this, when cooking with this frozen food 34A behind the moisture that volatilized when edible, food can be wizened, and mouthfeel is variation significantly.

On the contrary, in the present embodiment, on the peristome 16Aa of storage container 16A, send position, the corresponding rear of cold wind at F evaporimeter 23A,, make the cold wind that send towards storage container 16A with hold-over plate 30A covering rapidly, after hold-over plate 30A bears rapidly, deliver to again in the storage container 16A.Like this, with directly in storage container 16A, send the structure of cold wind to compare, owing to send the intensity of cold wind to weaken significantly in storage container 16A, institute is so that storage container 16A obtains cooling substantially equably, and frozen food 34A and packaging bag 35A are cooled under the very big situation of the temperature difference.

When under the little situation of this frozen food 34A and the packaging bag 35A temperature difference, being cooled, although the moisture among the food 34A also has volatilization, but because the temperature basically identical of frozen food 34A and packaging bag 35A, the moisture that from frozen food 34A, volatilizees, not only on the inner surface attached to packaging bag 35A, also on the surface attached to food 34A.That is to say, even the moisture evaporation of frozen food 34A, the part of its moisture turns back to again on the frozen food 34A, and when the volatilization of moisture among the frozen food 34A with when turning back to frost on the frozen food 34A and reaching balance, the moisture of frozen food 34A has just stopped volatilization.

In addition, when the temperature that makes packaging bag 35A when Defrost operation is higher than the temperature of frozen food 34A, though volatilize attached to the frost on the packaging bag 35A, and attached on the food 34A surface, but when sending cold wind, when the temperature that makes packaging bag 35A is lower than the temperature of frozen food 34A, because the temperature difference of frozen food 34A and packaging bag 35A is little, can all not move on the packaging bag 35A attached to the lip-deep frost of frozen food 34A, so the moisture of frozen food 34A can not continue volatilization.

Like this, owing to stopped moving of moisture among the frozen food 34A, when therefore eating, do not have dry sensation, good mouthfeel with the such frozen food 34A cooking.And then prevented since drying make food be cellular, because the surface area increase makes the phenomenon of food composition easy oxidation (so-called freezing rotten).

And, hold-over plate 30A is made by aluminium (coefficient of heat conduction is 237W/ (mK)) rapidly, by the cold wind that F evaporimeter 23A sends here, make rapidly that hold-over plate 30A becomes low temperature (30 ℃) at short notice very soon, therefore make the food that is positioned at hold-over plate 30A below rapidly because radiation and being cooled efficiently.

In addition, because hold-over plate 30A is not with the peristome 16Aa complete closed of storage container 16A rapidly, therefore even volatilize when the Defrost operation attached to the frost of storage container 16A inboard, the moisture after the volatilization also can escape into the outside of storage container 16A, thereby has prevented accumulating of frost.

After taking said structure, because on the storage container 16A peristome 16Aa in being contained in refrigerating chamber 6A, from the cold wind quilt hold-over plate 30A blocking rapidly that F evaporimeter 23A sends here, cold air can directly not delivered among the storage container 16A, makes the temperature in the storage container 16A even substantially.The temperature difference between frozen food 34A that is contained among the storage container 16A and the packaging bag 35A that wraps up them is reduced, prevented that the moisture of frozen food 34A from constantly volatilizing, frozen food 34A mouthfeel when the cooking is edible can not degenerated.

In addition, as this structure that can bring into play excellent results, hold-over plate 30A advantage made of aluminum is rapidly, and the weight of hold-over plate 30A is not really heavy rapidly, and the reception volume of storage container 16A can not diminish, and therefore implements expense is significantly risen.

(second embodiment)

Below, with reference to Fig. 7 and Fig. 8 second embodiment of the present invention described.The feature of second embodiment is that the peristome of hold-over plate and storage container rapidly is same size basically.

Described in first embodiment, hold-over plate 30A is used for making the cold air intensity of coming from F evaporimeter 23A to weaken rapidly, ideal situation is, that weakens is The more the better, but when the peristome 16Aa of storage container 16A is fully closed, the cooling of food only depends on the radiation of hold-over plate 30A rapidly among the storage container 16A, worries that therefore the food in the storage container 16A can not be sufficiently cooled.

Therefore in the present embodiment, storage container 16A as the stereoscopic display of Fig. 7 institute, the shape of hold-over plate 41A is the same with the shape of storage container 16A peristome 16Aa rapidly, the circumference of aluminium sheet 42A forms a plurality of width and is for example slotted hole 43A of 5mm, with the 41A of hold-over plate rapidly of this structure between closed position shown in Figure 7 and open position shown in Figure 8, be slidably mounted in storage container 16A above.In this case, because the existence of slotted hole 43A, hold-over plate 41A does not seal storage container 16A rapidly.

Owing to flow to the cold air of storage container 16A, flow into by the slotted hole 43A on the hold-over plate 41A rapidly, the intensity of delivering to cold air among the storage container 16A is significantly weakened, the frozen food 34A and the packaging bag 35A temperature difference that are placed among the storage container 16A are not cooled not bigly.In addition, although deliver to little than first embodiment of cold blast rate in the storage container 16A, the area of hold-over plate 41A is bigger rapidly, therefore cools off to be to be undertaken by the radiation of hold-over plate 41A rapidly, thereby food is efficiently cooled off.

After adopting such structure, because the major part of storage container 16A peristome 16Aa is all by hold-over plate 41A blocking rapidly, the intensity of delivering to the cold air among the storage container 16A is greatly weakened, identical with first embodiment, the volatilization of moisture among the energy freezing-inhibiting food 34A, and make frozen food 34A sufficiently cooled.In this example, since rapidly hold-over plate 41A be slidably disposed on storage container 16A above, therefore can by the hold-over plate 41A rapidly that slides, frozen food 34A be placed among the storage container 16A at an easy rate according to the amount that is placed on the frozen food 34A among the storage container 16A.

(the 3rd embodiment)

Below with reference to Fig. 9 and 10 explanations the 3rd embodiment of the present invention.The feature of the 3rd embodiment is that hold-over plate can bend in the centre rapidly.

In the Fig. 9 that shows storage container 16A, hold-over plate 51A is by two aluminium sheet 52A rapidly three-dimensionally, couple together by not shown attaching parts to constitute, and be that the center can bend with the mid portion.In addition, the circumference at aluminium sheet 52A forms slotted hole 53A.Like this, when hold-over plate 51A is in the state that is installed in storage container 16A peristome 16Aa rapidly,,, just frozen food 34A can be placed among the storage container 16A by raising the aluminium sheet 52A of forward position as Figure 10.

After taking such structure, because the major part of storage container 16A peristome 16Aa is by hold-over plate 51A blocking rapidly, therefore the intensity of the cold air that is sent to storage container 16A is greatly weakened, identical with first embodiment, the volatilization of moisture can make frozen food 34A fully cool off again in both can freezing-inhibiting food 34A.In this example, because hold-over plate 51A is arranged to middle bent form rapidly, therefore can be according to the amount that is contained in the frozen food 34A among the storage container 16A, hold-over plate 51A bends or whole raising rapidly, thereby frozen food 34A easily is placed among the storage container 16A.

(the 4th embodiment)

Below with reference to Figure 11-Figure 14, the 4th embodiment of the present invention described.The 4th embodiment makes the 51A of hold-over plate rapidly of the 3rd embodiment littler than the inboard shape of storage container 16A, and it can be fallen in the storage container 16A.

As shown in figure 11, frozen food 34A in storage container 16A amount allows hold-over plate 51A is in Figure 12 falls into storage container 16A like that rapidly more after a little while, and making rapidly, hold-over plate 51A becomes the state that is placed on the frozen food 34A.Be under this state, when from the cold air of F evaporimeter 23A when storage container 16A blows, enter because blow to the cold wind of frozen food 34A and be, therefore can make by the space of hold-over plate 51A blocking rapidly by basic evenly cooling by the slotted hole 53A of hold-over plate 51A rapidly.In this example,, so can bring into play the cooling effectiveness that produces by the radiation of hold-over plate 51A rapidly best because hold-over plate 51A contacts with the packaging bag 35A of frozen food 34A rapidly.

In addition, the amount of the frozen food 34A in storage container 16A to Figure 13 like that for a long time, hold-over plate 51A rapidly just is positioned at the peristome 16Aa place of storage container 16A like that to Figure 14, peristome 16Aa is interdicted.

Adopted such structure, because hold-over plate 51A can fall in the storage container 16A rapidly, therefore can be because the radiation of hold-over plate 51A and make the cooling of frozen food 34A have higher efficient rapidly.

(the 5th embodiment)

Describe below with reference to Figure 15 and 16 couples of the 5th embodiment of the present invention.The 5th embodiment is provided with secondary storage container exactly in storage container 16A, only implement the present invention in this pair storage container.

In the Figure 15 that shows storage container 16A, storage container 16A has secondary storeroom 61A three-dimensionally, and is only in this pair storeroom 61A, such to Figure 16, and the 4th the described hold-over plate rapidly of embodiment 51A fallen into.Like this, with among the frozen food 34A owing to moisture evaporation influences big thing, or the thing of long preservation as Figure 16, as the cooling object of hold-over plate 51A rapidly, can be preserved according to the kind of food so suitably.

Below accommodating container 50 is described in detail, Figure 18 is the skiagraph that is in first refrigerating chamber of closed condition, and Figure 19 will be in the lid of opening 70 to move to the skiagraph of the 1st refrigerating chamber of rear state.Figure 20 is the exploded view that has omitted the accommodating container 50 behind the lid 70.Figure 21 is the stereogram of accommodating container 50.Figure 22 makes the lid 70 of Figure 21 be in the stereogram that moves to the rear state.Figure 23 makes lid 70 be in the top view that is placed on state on the bottom surface 53.

Accommodating container 50 is rectangular box of upper shed, by synthetic resin for example polypropylene form.On the flange 55 of upper shed portion 54, the portable lid 70 that can be free to slide is being set removably.Lid 70 is closed the rear portion of peristome 54, and therefore the cold wind that the first cold air mouth is blown out can directly not blow in the accommodating container 50.

The front portion 51 of accommodating container 50 as Figure 20, forms recess 52, on this recess 52 ornamental strip 52a is set.

The inside in 55 liang of sides of flange part, by bolt 58, fixing the return portion 56 of extending from flange part 55 outer peripheral edges downwards and be embedded between accommodating container 50 periphery walls, be the reinforcement parts 57 of square shape substantially.

Be provided with at the rear portion of 55 liang of sides of flange part and making lid 70 between flange part 55, be fore-and-aft direction L shaped stator 61 that slide, that play the guide rail effect, it can also limit lid 70 and move upward, front portion at this stator 61, as shown in figure 25, formation makes lid 70 rising portions 62 that take out from the place ahead easily, that tilt upward.

Before being positioned at stator 61 front ends the side flange part 55 on, founding block 63a, the 63b of definite lid 70 positions respectively in front and back, after being positioned at stator 61 rear ends the side flange part 55 on, as shown in figure 24, be provided with lid 70 the inside side recesses and cooperate, stop lid 70 rearward to move to retainer 64 beyond the predetermined distance.

In addition, on the bottom surface 53 of accommodating container 50, as shown in figure 23, when founding the lid 70 that will take off and being placed on the bottom surface 53, the action of opening the door etc. and block 53a is determined in the position that do not move it.

Below lid 70 is described in detail.Figure 26 is the top view of lid 70.Figure 27 is the exploded view of lid shown in Figure 26.Figure 28 is the stereogram that Figure 26 lid is looked from the below.Figure 29 is the enlarged drawing in lid shown in Figure 28 bight.Figure 30 is the sectional drawing along the A-A line of Figure 26, and Figure 31 is the sectional drawing along the C-C line of Figure 26.Figure 32 is the sectional drawing along the D-D line of Figure 26.

Shown in Figure 26,27, lid 70 by the metallic plate 71 of for example aluminum with cover metallic plate 71 outer peripheral edges, become mouthful synthetic resin of word shape for example the framework 75 of ABS system constitute, on metallic plate 71, the through hole 72 of determining the position is located in the substantial middle on each limit.Framework 75 is made of upper frame body 75a and lower frame body 75b.Shown in Figure 27,30,32, on lower frame body 75b, the upright block 76 of determining the position by the through hole 72 that injects metallic plate 71 of establishing.Like this, lid 70, under the state, 75a covers with upper frame body, by for example ultrasonic welding it is formed as one then in being in the block 76 that through hole 72 with above-mentioned metallic plate 71 inserts lower frame body 75b.

In addition, when the refrigerating chamber room temperature is low, each elements constrict, because the amount of contraction of resin system framework 75 is bigger than metallic plate 71, therefore, between the inner peripheral surface of the outer peripheral face of metallic plate 71 and framework 75, and between through hole 72 and block 76, be provided with than shrinking difference gap big, about for example 0.4-1mm.

As Figure 28 and shown in Figure 31, at the central portion of lid 70 the inside left and right sides, be provided with accommodating container 50 retainers 64 and contact, limit the protuberance 78 that lid 70 rearward moves, in the front and back of this protuberance 78, form the ditch portion 77 that retainer 64 slides.In addition, the front and back end in this ditch portion 77 is wearing and is being used for and block 63b is chimeric, be used for determining lid 70 positions breach 79.

Protuberance 78 and ditch portion 77 front and back are being provided with symmetrically, and no matter lid 70 from which direction can both be installed on the accommodating container 50.

Below, describe with reference to the action of Figure 18,19,21,22 pairs of lids 70.

Shown in Figure 18,21, when lid 70 was in the state that is installed on the accommodating container 50, the dual-side of lid 70 was placed on the flange part 55, and the front portion of lid 70 is determined the position with breach 79 by contacting each block 63a, 63b, at this moment, retainer 64 is positioned at the ditch portion 77 of lid 70.

When the user wants to take out frozen food,, door 9 is pulled out, accommodating container 50 is pulled out to outside the refrigerator,, add to the difficulties for the taking-up frozen food, therefore allow lid 70 move to the rear if lid 70 is arranged as Figure 19.At this moment, one side is lifted the place ahead of lid 70, and one side to pusher, comes out block 63b it from breach 79, just can move backward.Along with retainer 64 slides in ditch portion 77, lid 70 just rearward moves.When moving to the certain distance at rear, the protuberance of lid 70 78 contact retainers 64 prevent that lid 70 from falling from the rear.

In addition, when mobile, lid 70 can not fall from accommodating container 50, thereby contacts with stator 61, limits it thus in action last, left and right directions.

After the user takes out frozen food, lid 70 is forwards moved, make anterior and breach 79 contact blocks 63a, 63b, thereby it is closed.Even the user forgets it is forwards returned, the rear end face of lid 70 also can pass through the contact back face wall, and with lid 70 auto-closings, thereby opening 54 is closed.

In addition, when preserving higher frozen food, or for the user who does not need purposes of the present invention, make the front portion of lid 70 be the shape that erects sheet 62, pull out to oblique the place ahead, allow the side of lid 70 in stator 61, slide,, just it can be taken off from accommodating container 50 by removing the restriction of stator 61.

In this case, make the width of lid 70 littler than the length of accommodating container 50, make the length of lid 70 littler than the width of accommodating container 50, just it can be placed on as shown in Figure 23 on the bottom surface 53 of accommodating container 50, can rapidly lid 70 be loaded onto as required like this, when not required, just place it in the bottom surface of accommodating container 50, can prevent losing of lid 70.Further, lid 70 usefulness metallic plates are made, can be improved its refrigerating capacity as coldplate.

The following describes effect of the present invention.Usually, frozen food is cooked when moisture is for frozen state in keeping food, has good mouthfeel, if make the moisture evaporation in the frozen food, mouthfeel will be bad.

The reason of moisture evaporation is because of following phenomenon in the frozen food.That is to say, as shown in Figure 39, frozen food 90 all uses package members 91 such as bag, polyethylene packaging paper or TUPPER container packing usually, in the time of in being housed in first refrigerating chamber 5, directly blow on the package member 91 from the cold airflow of cold air mouth 31, make the temperature of package member 91 become very low.Just, the target temperature of first refrigerating chamber 5 is-18 ℃, and when the temperature of cold air was exactly-30 ℃, for for-18 ℃, the temperature of package member 91 just reached-30 ℃ with respect to the temperature of frozen food 90.Like this, the temperature of package member 91 is just much lower than the temperature of frozen food 90, and the moisture of volatilization is as frost, attached to the inner surface of package member 91 from frozen food 90.In this case, owing to all be frost attached on package member 91 inner surfaces from the moisture of frozen food 90 volatilizations, saturated steam density in the package member 91 is risen, so just make the moisture in the food 90 continue volatilization, Hui Fa moisture is constantly on the inner surface of form attached to package member 91 with frost simultaneously.The existence of above-mentioned phenomenon causes moisture in the frozen food 90 to move to the inboard of package member 91, makes that a lot of levels in the frozen food 90 are volatilized to be fallen.

In addition, when carrying out Defrost operation, because the hot-air that the energising of F evaporator defrost heater 25 produces enters, the temperature of first refrigerating chamber 5 is risen, when the temperature that makes frozen food 90 is lower than the temperature of air in the package member 91, attached to the volatilization of the frost in the package member 91, this down, as shown in figure 40, although form frost, when Defrost operation finishes cooling operation beginning attached on the frozen food 90, because cold air, when the temperature that makes package member 91 reduces rapidly than the temperature of frozen food 90 once more, volatilize again attached to frozen food 90 lip-deep frosts, attached to the inboard of package member 91.

Because above-mentioned repetitive operation, a lot of moisture in the frozen food 90 has moved to the inboard of package member 91.Like this, when cooking with this frozen food 90 behind the moisture that volatilized when edible, food is dry, and mouthfeel is very bad.

On the contrary, in the present embodiment, the rear portion of peristome 54 that the F evaporimeter 23A that reception is sent here from the cold air blow-off outlet 31 that is located at accommodating container 50 back sides tops generates the accommodating container 50 of cold air is covered by lid 70, the cold wind that the cold air mouth 31 that is located at accommodating container 50 upper rear portion is sent, blow on the lid 70, by above the accommodating container 50 that interdicts by circulating.Like this, and directly send the structure of cold wind to compare in accommodating container 50, the intensity of the cold air that contacts with frozen food weakens significantly, thereby frozen food 90 and package member 91 are cooled under the very big situation of the temperature difference.

In addition, be cooled in any case, although the moisture in the frozen food 90 also has volatilization, but owing to be that frozen food 90 and package member 91 are cooled under the little situation of the temperature difference, the moisture of volatilization from frozen food 90, not only on the inner surface attached to package member 91, also on the surface attached to food 90.Like this, even the moisture evaporation of frozen food 90, the part of its moisture turns back to again on the frozen food 90, and when the volatilization of moisture in the frozen food 90 with when turning back to frost on the frozen food 90 and almost reaching balance, the moisture of frozen food 90 has just stopped volatilization.

In addition, when the temperature that makes package member 91 after the defrosting is higher than the temperature of frozen food 90, volatilize attached to the frost on the package member 91, return attached on food 90 surfaces, when sending cold wind once more, when the temperature that makes package member 91 is lower than the temperature of frozen food 90, because the temperature difference of frozen food 90 and packaging bag 91 is little, therefore can all not move on the package member 91 attached to frozen food 90 lip-deep frosts, so the moisture of frozen food 90 can not continue volatilization.

Further, lid 70 has suppressed that hot-air enters in the accommodating container 50 in the Defrost operation, has therefore reduced the rising of frozen food 90 temperature in the Defrost operation.Like this, after cooling operation beginning, even the temperature of package member 91 descends rapidly, it also can keep with food the less temperature difference being arranged, thus the volatilization of moisture in the freezing-inhibiting food 90.

Like this, owing to stopped moving of moisture in the frozen food 90, when therefore eating, do not have dry sensation, good mouthfeel with 90 cookings of such frozen food.So also prevented to quicken the phenomenon of food composition oxidized (so-called freezing rotten) because drying makes food be cellular, surface area increases.

In addition, because the present invention's first refrigerating chamber is the drawer type storeroom of accommodating container 50 being pulled out by the action of opening the door, lid 70 can rearward slide on accommodating container 50, therefore become simple structure, and, just can make frozen food easily be removed and put into by lid 70 simple on-off actions.In addition, after the user takes out food,,,, also the peristome 54 of accommodating container 50 can be covered by making the back end in contact refrigerator back face wall of lid 70 when container 50 being moved backward when closing even forget lid 70 is recovered former states.

Furtherly, owing on accommodating container 50 of the present invention, be provided with the upwards stator 61 of action of restriction lid 70, and by lid 70 is forwards slided, can remove the restriction of stator, therefore under the situation that does not need lid 70, it easily can be taken off from accommodating container 50, can also prevent from when lid 70 moves, to make because of carelessness it to fall from accommodating container 50.

Further, the present invention is provided with the rising portions 62 of inclination upward by the front portion at stator 61, makes lid 70 can cross over the position of moving towards the place ahead and determines sheet, and easily take off from accommodating container 50.

Further, the present invention, falls from the rear in the time of therefore preventing that lid 70 is rearward mobile by restriction lid 70 retainer 64 that moves of predetermined distance rearward is set on accommodating container 50.

Further, the present invention is provided with the ditch portion 77 of retainer 64 slips of accommodating container 50 when making lid rearward mobile in the inside of lid 70, the protuberance 78 that contacts with retainer 64 when rearward predetermined distance moves with lid 70 utilizes simple structure that lid 70 can be moved forward and backward like this.

Further, the present invention is owing to be provided with the ditch portion 77 of lid 70 and protuberance 78 front and back symmetrically, therefore when the user when lid takes off state it is installed once more, can install arbitrarily from fore-and-aft direction, improved convenience.In addition, in the present embodiment, only be provided with ditch portion 77, also can be provided with from the teeth outwards, can install with positive and negative arbitrary face like this in the inside of lid 70.

Further, when synthetic resin such as adopting yielding polypropylene is made accommodating container 50, flange part 55 is expanded laterally, therefore worry that lid 70 can not move forward and backward, the present invention is owing to be provided with the reinforcement parts 57 of inhibition distortion in the side of accommodating container 50, by the distortion of the flange part 55 that prevents to be used to slide, improved the slidably property of lid 70.

Further, shown in the dotted line among Figure 18, the front portion of lid 70 is tilted upward, can make the cold air that comes from the rear towards the upper reaches, like this, suppressed in accommodating container 50, directly to send cold wind, thereby the temperature difference between frozen food 90 and the package member 91 is reduced, prevented the evaporation of moisture in the frozen food 90.

Further, the present invention as lid 70, makes lid 70 at short notice be cooled to very low temperature from the cold air of F evaporimeter 23 by metallic plate 71, for example-30 ℃, makes the food that is positioned at lid 70 belows because radiation and being cooled off efficiently.

Further, because on the peristome 54 of the accommodating container 50 in being contained in first refrigerating chamber 5, the cold wind that F evaporimeter 23A send is by 71 blockings of lid 70 metallic plates, cold air can directly not delivered in the accommodating container 50, makes the temperature in the accommodating container 50 roughly even.Therefore the temperature difference that is placed on the frozen food 90 in the accommodating container 50 and packs between its package member 91 is very little, can prevent that like this moisture in the frozen food 90 from constantly volatilizing, thereby prevent frozen food 90 bad problem of mouthfeel when the cooking is edible.

Further, when drawing metallic plate 71 to move forward and backward with wet hand push, can worry that the water of watch face freezes, the present invention is owing to be made of lid 70 metallic plate 71 and the resin system framework 75 that covers metallic plate 71 peripheries, will be than the handle of the big framework 75 of metallic plate 71 specific heats as lid 70, hand is frozen in the time of preventing reliably thus that lid 70 from moving forward and backward.

Further, when the refrigerating chamber room temperature was low, metallic plate 71 and framework 75 were shunk, and the amount of contraction of resin system framework 75 is bigger than metallic plate 71, embed moulding metallic plate 71 and framework 75 are combined closely if use, and just occurred easily being out of shape or drawbacks such as crackle.Yet in the present invention, between the inner peripheral surface of metallic plate outer peripheral face and framework, be provided with the gap, therefore can prevent above-mentioned drawback.

Further, the present invention is because the width of lid 70 is littler than the length of accommodating container 50, and the length of lid 70 is littler than the width of accommodating container 50, and lid 70 can be placed on the bottom surface 53 of accommodating container 50.Like this, as required, lid 70 can be loaded onto rapidly, also can be prevented losing of lid 70.

Below with reference to Figure 33-35 another embodiment is described.In the present embodiment, lid 70 all covers the peristome 54 of accommodating container 50.When above-mentioned lid 70 exists, can not make cooling not enough because cold air is directly sent to, but can not cause the not enough occasion of cooling according to cooling capacity or air output, can shown in Figure 33,34, use the lid 70 that comprehensively covers.In this case, can not exclusively seal, between lid 70 and accommodating container 50, the gap is set, the hole of logical cold air also can be set on metallic plate 71.

In addition, when the width of lid 70 bigger than the length of accommodating container 50, or the length of lid 70 is when bigger than the width of accommodating container 50, it is little to make the width ratio of lid 70 be located at the length of accommodating container 80 of another storeroom (being second refrigerating chamber 6 as shown in figure 35) here, make the length of lid littler, so just can make on its bottom surface that is placed on accommodating container 80 81 than the width of above-mentioned accommodating container.At this moment, the same with situation in being placed on accommodating container, can rapidly lid 70 be loaded onto when needing, can prevent that also lid 70 from losing.Furtherly, use metallic plate, improved its refrigerating capacity as coldplate as lid 70.

In addition, in the above-described embodiments, be the situation of on the whole width of accommodating container, opening being closed, but also shown in the image pattern 36-38 like that, lid 70 is set on the part of accommodating container, allow it as storage space with effect of the present invention.

Particularly, for example, in the epimere container 82 of second refrigerating chamber, 6 accommodating containers 80, uprightly from the bottom surface establish a dividing plate 83 of cutting apart storage space at left and right directions, flange part 84 is set on the inwall of a side, lid 70 moves forward and backward with last embodiment is the same on the dividing plate 83 and on the flange part 84, makes the storage part that lid 70 is set as the storage space with effect of the present invention.In this case, the user will need the food of cooling separately and prevent to preserve respectively because of the dry food of moisture evaporation, improve user's convenience.

In addition, said structure, be not limited on the embodiment, in the scope of not violating spirit of the present invention, can make many variations, for example, lid 70 is not limited to slip on accommodating container, also can be arranged on the refrigerator body 1 that is formed by interior case etc., in addition, the shape that cold air directly is not blown into the cold air blow-off outlet 31 in the accommodating container 50 can tilt obliquely upward.

The present invention is applicable to the refrigerator with the refrigerating chamber that is in the freeze space.
