Figure 17 be expression patent documentation 1 be the open communique 2000-304435 number described existing freezer of Japan Patent an embodiment want portion's sectional side view.

As shown in figure 17, the part of the storeroom of the freezer main body 2 that is constituted by heat insulating box 1 be refrigerating chamber 8 by the top heat insulation dividing body 5 in top, the following heat insulation dividing body 6 in bottom, be divided into temperature band different refrigerating chamber 7 and vegetable compartment 9.In addition, the peristome of refrigerating chamber 8 is provided with between left and right peristome is divided into dividing body 11 up and down.

Cold air in the rear side that is arranged at refrigerating chamber 8 generates the pressure fan 14 that chamber 12 disposes evaporimeter 13 and cold air is supplied with, circulated to refrigerating chamber 7, refrigerating chamber 8, vegetable compartment 9, the defrosting heater 15 that starts when the lower space of evaporimeter 13 disposes defrosting.

Door 21 and lower gate 22 all are the doors of the refrigerating chamber 8 of drawer type, be wholely set at its rear and be supported on

framework

24,25 container 27 and bottom container 28 respectively, in addition, the rear of refrigerating chamber 8 is provided with the cold air distributor chamber 30 that will be distributed to each chamber by the cold air of evaporimeter 13 generations, is formed with a plurality of cool-air feed mouths in its front.

In addition, the bottom in the container 27 in the refrigerating chamber 8 and the bottom container 28 is provided with pallet 31, on each container 27 and bottom container 28, is formed with

cold air path

27a, 28a between before and after its bottom.

In addition, be provided with in the front of cold air distributor chamber 30 towards cool-air feed mouth 30a, the 30b of the upper open face of container 27, bottom container 28, and the cool-air feed mouth 30c corresponding with the cold air path 27a of container 27, the cool-air feed mouth 30d corresponding with the cold air path 28a of bottom container 28.Therefore, be not only container 27, in bottom container 28, the cold air from cold air distributor chamber 30 directly circulated to its cold air path 28a, can improve the cooling velocity of food.

Like this, the pallet 31 in container 27 and the bottom container 28 cools off fast, and by the upper open face cool-air feed to each container, the food in the container can be at short notice with food product refrigeration from cooling off up and down.

In the above-mentioned present formation, for example, under the situation of opening door 21, take in the container 27 of food and pull out to the outside with door 21 interlocks, therefore, have and see food, the very easy taking-up of taking in easily and put into this advantage of food.

But, in the above-mentioned present formation, put into to pallet 31 under the situation of the food before freezing, especially put under the situation of the high food of temperature, because pallet 31 does not have cool storage function, therefore, pallet 31 heats up at once, though food self is cooled, conducts heat via pallet 31, cause other food to heat up, worry may make the part that movable bacterium has been melted, has been suppressed on the surface of taking in food of freezing preservation breed.Especially worry to take in the melting under the big situation of degree of surface of food, the quality when freezing again worsens very serious.In addition, during the cooling beginning, because the pallet 31 that heats up need cool off pallet 31 in cooling food, the speed of cooling food is slack-off, and freezing quality reduces.

In addition, opened door at 21 o'clock, under the situation that cold air sprays from cool-air feed mouth 30c, the distance of cold air path 27a from cool-air feed mouth 30c to container 27 becomes far away, extremely reduce to the amount that cold air path 27a circulates from the cold air of cool-air feed mouth 30c ejection, most of to cold air path 27a dispersion in addition.Therefore, uncolled at the frozen food that cold air stores above by 27a, and be exposed to extraneous air, temperature is risen, and the air in the refrigerating chamber 8 is stirred, and replacing of the cold air in extraneous air and the refrigerating chamber 8 is serious, therefore, closing the cooling of door after 21 need expend time in, and the time that frozen food is exposed to above the temperature of the set point of temperature of refrigerating chamber 8 increases.Thus, the part that movable bacterium has been melted, has been suppressed on the surface of taking in food of freezing preservation is bred.Especially the surface to melt degree more big, the portion that freezes again that closes behind the door 21 is more many, quality worsens very serious.Even put into from the outside under the situation of food, owing to follow the inflow of the extraneous air of the opening of door 21 when putting into, the temperature in the container 27 rises, even in the cooling after closing door 21, also need the time to be refrigerated to set point of temperature, therefore, the cooling time of putting into food increases.

In addition, even according to stop cooling when door 21 is opened, namely under the situation about not considering from the mode of cool-

air feed mouth

30a or 30c ejection cold air, though degree reduces, frozen food still is exposed in the extraneous air, so temperature rises, and causes same consequence.

Like this, in the present formation, the problem that the quick-frozen of the inhibition that existence is interfered the heat of other food and the food of putting into can not and be deposited is being sought to keep the taking-up of food and the simplification of putting at present and is suppressed the intensification that extraneous air causes and keep the method for quality.

In addition, opened door at 121 o'clock, under the situation of the frozen food of before the zone with the rear side of cold-storage spare 150 adjacency exists, preserving 157, extraneous air in 150 pairs of inflow containers of cold-storage spare 127 cools off, therefore, compare with present freezer, can remain low temperature around the frozen food 157.In addition, even in higher the putting under the situation that food 158 is positioned at same containers 127 of temperature, compare with present freezer, can suppress to interfere the intensification that brings from the heat of putting into food 158.

Like this, in the storeroom that possesses cold-storage spare 150 is the container of refrigerating chamber 108, the zone that is positioned at the front face side of door 121 sides can be used as the zone of taking in that possesses cold-storage spare 150, use is distinguished as the general freezing zone i.e. preservation portion that does not have cold-storage spare 150 in the zone that will be positioned at rear side, thus, for the user, can be when putting into the food of heat, make that to preserve the zone put into food clearer and more definite, also can reduce the heat affecting of the frozen food 157 of putting into 158 pairs of preservations of food.

Afterwards, as shown in Figure 2, when door 121 is closed, be judged as door 121 by not shown checkout gear and close, the running of freeze cycle (not shown) begins, and refrigerant is to evaporimeter 113 circulations and generate cold air, simultaneously, pressure fan 114 turns round and makes circulating cold air, thus, begins to cool down.Cold air 108 is supplied with from refrigerating chamber ejiction opening 153 to refrigerating chamber, to frozen food 157 and put into food 158 and cool off.At this moment, the indirect cooling that brings by the cold air that ventilates around of frozen food 157, cool off from these two kinds of devices of direct cooling of following cold-storage spare 150.

At this moment, when cooling off putting into food 158, the part of cold air also is used for the cooling of cold-storage spare 150.But for the cooling of refrigerating chamber 8, being cooled to than set point of temperature is-20 ℃ high, and therefore, little with the temperature difference of the latent heat temperature-15 of cold-storage spare 150 ℃, cold air is mainly used in the cooling of food.In addition, 108 cold air of supplying with ventilate in container 127 from refrigerating chamber ejiction opening 153 to refrigerating chamber.At this moment, the put into food 158 of mounting above cold-storage spare 150 that is positioned at the frozen food 157 of upstream side and is positioned at the downstream from the wind path of the cold gas of refrigerating chamber ejiction opening 153 ejection is cooled.At this, frozen food 157 and put into food 158 more with the latent heat temperature of cold-storage spare 150 namely-15 ℃ approach, frozen food 157 and the temperature difference of putting into food 158 and cold air just more approach with the temperature difference of cold air and cold-storage spare 150, and therefore, the component that cold air is used for the cooling of cold-storage spare 150 increases.But, for example, frozen food 157 and putting under food 158 situation for fish or meat, owing to contain mineral matter and amino acid etc., therefore, maximum ice crystallization generating zone mostly is 0 ℃～-10 ℃, in this temperature band, mainly by the major part of cold air to frozen food 157 and put into food 158 and cool off.On the basis of the cooling that this cold air brings, by the cooling from cold-storage spare 150, rapidly by maximum ice crystallization generating zone.

Like this, during the pulling out of the container 127 under the situation that door 121 is open, by cold-storage spare 150, cooling in the container 127, the temperature of the frozen food 157 that can suppress to store rises, and the extraneous air of putting into of putting into food 158 and flowing into also by 150 coolings of cold-storage spare, therefore, can freeze at short notice.

In addition, when door 121 is open, be exposed in the extraneous air at first, be exposed to when door 121 is closed in the extraneous air to part the latest and be provided with cold-storage spare 150, therefore, can further control the intensification of frozen food 157, the cool time that food 158 is put in shortening.In addition, cold-storage spare is positioned at the front, therefore, under whole situations of pulling out to the outside with container not, just food can be accommodated near the cold-storage spare, and can carry out quick-frozen, therefore, can suppress extraneous air and flow into to container, easily carries out taking in of food.

In addition, therefore the structure of cold-storage spare 150 for can easily loading and unloading on container 127, be easy to cleaning, also can be applied to other devices.In addition, even when taking in putting into food 158 with wet hand etc., just in case hand contacts and cling under the situation of cold-storage spare 150, cold-storage spare 150 is together unloaded and heat etc., can easily carry out the processing that hand and cold-storage spare 150 are separated.

In addition, even possess women that at least a portion of the container of cold-storage spare 150 the is made as general height height that hand also can reach of not bending over, therefore, be positioned at can imaginary majority the hand easy to reach, be about 800mm apart from the height that face is set, same be the position of 800mm because cold-storage spare 150 is positioned at the height that distance arranges face, therefore, can easily carry out the loading and unloading of cold-storage spare 150, be bonded at cold-storage spare 150 at hand and under the situation about can not separate, can dispose easily.In addition, in the embodiment 1, at least a portion that possesses the container of cold-storage spare 150 is established and highly is 800nm, but generally is position the most easy to use between 600nm～1200nm, therefore, is preferably placed in this scope.

In addition, cold-storage spare 150 is with respect to wide and depth 300mm, its height dimension is little, is 20mm, therefore, even inner cold-storage dosage equates, area is set also can increases of food, though the cold-storage dosage of cold-storage spare inside equate, can also can increase with the area of Food Contact, can when keeping the taking in property of food, further suppress intensification, the cool time when shortening food is put into of foodstuff storing.And, can take in a lot of frozen food 157 and put into food 158, in addition, can take in big frozen food 157 and put into food 158.In addition, can obtain big frozen food 157 and put into the contact area of food 158 and cold-storage spare 150, therefore, can suppress to heat up, shorten cool time.

In addition, in the embodiment 1, used cold-storage spare as the cold-storage parts with cool storage function, but for example metallic and thickness is the above hold-over plate of 5mm so long as possess the parts of cool storage function and can be suitable for.

In addition, door 121 is drawer types, therefore, compares with the swinging door, and the cold air that temperature is low is difficult to escape above container, intensification that can freezing-inhibiting food 157, shortens the cool time of putting into food 158.

In addition, in the embodiment 2, about the part identical with the formation that illustrated and technological thought in the embodiment 1, omit detailed explanation, about the formation of the applicable technological thought identical with the content described in the embodiment 1, can realize with the technology contents described in the embodiment 1 and constitute the formation of combination.

As shown in the figure, the cold-storage parts with cool storage function be cold-storage spare to be placed at storeroom in 150 years be that the inside bottom that is arranged in the refrigerating chamber 108 with the container 127 of the epimere of two sections formations is above the bottom surface side, and be arranged at door 121 sides.

In addition, the fixed mechanism that suppresses the movement of cold-storage spare 150 is depressed part 160, and the inscape that this depressed part 160 is containers 127 is the part of resin component, constitutes integratedly with container 127.

Like this, depressed part 160 according to the front side that is arranged at container 127 namely the cold-storage spare 150 of door 121 sides can be owing to the inertia of the on-off action of door 121 rearward mobile mode arrange.

The food that food maintaining body 161 is located at the top food that cold-storage spare 150 is set arranges face 162, be at cold-storage spare 150 at least the rear, namely the opposition side of door 121 sides arranges face 162 more outstanding shape than food.Thus, the food that suppresses cold-storage spare 150 arrange place on the face 162 put into food 158 since the on-off action of door 121 to more moving by the incorporating section i.e. preservation portion 163 at rear than cold-storage part 150.

In addition, be not only the rear of cold-storage spare 150, food maintaining body 161 also can arrange on four limits entirely according to surrounding the mode that food arrange face 162, and in the embodiment 2, food maintaining body 161 is striden food, and that the periphery of face 162 is set is continuous.

Like this, in the storeroom that possesses cold-storage spare 150 is the container 127 of refrigerating chamber 108, the zone that is positioned at the front face side of door 121 sides can be divided and used as the zone of taking in that possesses cold-storage spare 150, will be positioned at than taking in the zone and more distinguish uses by the zone of rear side (rear side) as the general zone i.e. preservation portion 163 that does not have cold-storage spare 150.

In addition, possess cold-storage spare take in the food maintaining body 161 that the zone possesses and the 127a of boundary portion that does not possess the general freezing zone i.e. preservation portion 163 of cold-storage spare forms smoothly via rake 127b.The 127a of boundary portion, rake 127b all be container inscape a part and form as one, and improve rigidity, the 127a of this boundary portion is the fixed mechanism that prevents the movement of depressed part 160 and cold-storage spare 150.

Cold-storage spare 150 can load and unload, and possess the loading and unloading assisted parts 170 that mode that the finger according to user when the place ahead of the depressed part 160 of container 127 loading and unloading cold-storage spare 150 can enter forms at recess, possess loading and unloading maintaining part 171 in recess formation at the container with these loading and unloading assisted parts 170 opposed rear portion side.They are sticked in respectively to possess on cold-storage spare 150 and reach the cold-storage spare that forms at protuberance at the cold-storage spare loading and unloading assisted parts 172 that recess forms loads and unloads maintaining part 173.

In the embodiment 2, the injection portion that uses when injecting cold-storage liquid in the gabarit container of cold-storage spare forms this cold-storage spare loading and unloading assisted parts 172.

In addition, link the line 3D-3D of this cold-storage spare loading and unloading assisted parts 172 and cold-storage spare loading and unloading maintaining part 173 by the center line on the left and right directions of cold-storage spare.

In addition, because possessing below heat insulating box 101 and be used for making the castor 151 that freezer main body 102 can easily move and the storeroom that is arranged at the below of refrigerating chamber 108 is vegetable compartment 109, being arranged at above ground 152 height above the cold-storage spare 150 that has on the refrigerating chamber 108 is the position of 800mm.

In addition, cold-storage spare 150 is by lower than the solidification point of common freezing food and lower and constitute than the material that the high temperature of the temperature of refrigerating chamber 108 namely has latent heat in-15 ℃ than the temperature of maximum ice crystallization generating zone, and wide 300mm, depth 300nm, height are thickness 20mm.Charging quantities in the cold-storage spare 150 are held following heat, and this heat has the atmospheric temperature of the amount that is equivalent to be arranged at top volume of food, for example is equivalent to from the latent heat amount of the summation that is equivalent to 30 ℃～-10 ℃ latent heat amount and sensible heat amount.That is, under the situation that cold-storage spare 150 freezes, when putting into normally used general food, can not melt fully.

Freezer ejiction opening 153 is ejiction openings that ejection is used for the cold air of cooling refrigerating chamber 108, and refrigerating chamber outlet 154 is with the outlet of refrigerating chamber 108 cooled cold air from refrigerating chamber 108 Returning evaporimeters 113.Feed path 155 is passages that the cold air for refrigerated compartment 107 ventilates.

That takes in the frozen food of having preserved 157 and newly putting into of preserving in the container 27 on cold-storage spare 150 puts into food 158.

In addition, with respect to the level height 163a of the preservation portion 163 in the freezing zone of the frozen food 157 in the accommodating container 27, the level height 162a that takes in the food mounting portion 162 of taking in the zone that puts into food 158 is disposed at the high position.

In addition, be used for the cool-air feed of refrigerated compartment 107 and vegetable compartment 109 and circulate not shownly, but carry out cool-air feed and circulation by the cooling air duct different with the cooling air duct of cooling refrigerating chamber.

Freezer about the embodiment 2 that constitutes as mentioned above describes its action below.

Cold-storage spare 150 and frozen food 157 are cooled and freeze to namely-20 ℃ of the set points of temperature of refrigerating chamber 108.As shown in the figure, the food that food 158 is positioned over cold-storage spare 150 is opened and will be put into to door 121 arrange under the top situation of face 162, put into food 158 and take heat by force by the cold-storage spare 150 that freezes to-20 ℃ putting into the back, begin to cool down.In addition, flow into the extraneous air of container 127 also by 150 coolings of cold-storage spare, compare with present freezer, the air in the container 127 can keep low temperature, also can cool off by this Cryogenic air and put into food 158.

In addition, opened door at 121 o'clock, arrange at the food with cold-storage spare 150 under the situation of the frozen food of preserving before face 162 existence 157, be cooled by cold-storage spare 150 frozen food 157, simultaneously, extraneous air in 150 pairs of inflow containers of cold-storage spare 127 cools off, and compares with present freezer, can remain low temperature around the frozen food 157.In addition, compare with present freezer, can suppress to interfere the intensification that brings from the heat of putting into food 158.

Afterwards, as shown in the figure, when door 121 is closed, be judged as door 121 by not shown checkout gear and close, the running of not shown freeze cycle begins, and refrigerant is to evaporimeter 113 circulations and generate cold air, simultaneously, pressure fan 114 turns round and makes circulating cold air, thus, begins to cool down.Cold air 108 is supplied with from refrigerating chamber ejiction opening 153 to refrigerating chamber, to frozen food 157 and put into food 158 and cool off.At this moment, frozen food 157 and put into food 158 and cool off by the cold air that ventilates with from the cooling of following cold-storage spare 150.The part of cold air also is used for the cooling of cold-storage spare 150.But for the cooling of refrigerating chamber 108, being cooled to than set point of temperature is-20 ℃ high, and therefore, little with the temperature difference of the latent heat temperature-15 of cold-storage spare 150 ℃, cold air is mainly used in the cooling of food.In addition, the ventilation of cold air constitutes to container 127 interior ventilations by not shown ventilation.At this moment, the food of cold-storage spare 150 arranges face 162 and places and cover frozen food 157 and put into food 158, therefore, and mainly to frozen food 157 with put into food 158 and cool off.At this, frozen food 157 and put into food 158 more with the latent heat temperature of cold-storage spare 150 namely-15 ℃ approach, cold air is more many for the component of the cooling of cold-storage spare 150, but, for example, frozen food 157 and putting under food 158 situation for fish or meat, solidification point is near 0 ℃, maximum ice crystallization generating zone mostly is to-10 ℃, in this temperature band, mainly by the major part of cold air to frozen food 157 and put into food 158 and cool off.On the basis of the cooling that this cold air brings, by the cooling from cold-storage spare 150, rapidly by maximum ice crystallization generating zone.

Like this, under the situation that door 121 is opened, container 127 is pulled out from freezer main body 102, when cold-storage spare 150 is exposed in the extraneous air, by cold-storage spare 150, cooling in the container 127, the temperature of the frozen food 157 that can suppress to store rises, and the extraneous air of putting into of putting into food 158 and flowing into also by 150 coolings of cold-storage spare, therefore, can freeze at short notice.

In addition, the thermal capacity of cold-storage spare 150 is big, therefore, follows the part of the moisture in the extraneous air that the extraneous air of door 121 switching flows in cold-storage spare 150 dewfall or frosting.Under long situation of the time that next time opens and closes of door 121, distillation or evaporation in the cooling air that utilizes the cooling running to circulate and from surface removal, highly humid air is in evaporimeter 113 frostings, circulation by the cooling air in the cooling running as described below, remove moisture and the frost of the surface attachment of cold-storage spare 150, this cooling running circulates the Cryogenic air that has dehumidified once again, and the moisture of cold-storage spare 150 is removed in circulation around cold-storage spare 150.But, carry out at short notice under the situation about next time opening and closing of door 121, namely, cold-storage spare 150 residual owing on once under the state of the moisture that adheres to of the switching of door 121 and frost, open door 121 and put under the situation of food, under the situation of the food lower temperature of especially putting into, put into and close door at 121 o'clock will putting into food 158, because reaction is put into food 158 and is easily slided on cold-storage spare 150.In addition, the moisture that exists between this food and the cold-storage spare 150, namely therefore frost or ice be difficult to distil or evaporate because the cooling air is difficult to circulation, easily residual, opened door again under residual state at 121 o'clock, and its reaction also may make the food slip.Like this, even contingency produces and makes cold-storage spare 150 and put into the power that food 158 slides and moves to the rear of container 127 owing to the action of the switching of carrying out door 121 in a jumble or continually, cold-storage spare 150 is that the 127a of boundary portion conflicts with fixed mechanism, frozen food 157 and put into food 158 and conflict with food holding member 161.Therefore, cold-storage spare 150 is that the 127a of boundary portion can prevent the movement of incorporating section 163 rearward by fixed mechanism, frozen food 157 and put into food 158 and can prevent that by food maintaining body 161 from the food of cold-storage spare 150 face 162 being set stops at food to moving of preservation portion 163 position on the face 162 is set.In addition, about cold-storage spare 150 or frozen food 157 and put into food 158 movement forwards, can prevent the movement of any by the place ahead wall of container 127.

Because, can prevent from following the movement of cold-storage spare 150, putting into food 158 arranges face 162 from food and departs from, and, can suppress to put into the movement of self sliding and causing of food 158, even the reaction that exists the switching etc. of door 121 to bring, frozen food 157 and the heat of putting into food 158 are absorbed by cold-storage spare 150 expeditiously, the cool time in the time of can suppressing to heat up, shorten food and put into.

As mentioned above, in the embodiment 2, the food that food maintaining body 161 is located at the top food that cold-storage spare 150 is set arranges on the face 162, be at the rear of cold-storage spare 150 namely the opposition side of door 121 sides than food face 162 more outstanding shape is set.Thus, the food that suppresses cold-storage spare 150 arrange place on the face 162 put into food 158 since the on-off action of door 121 to than cold-storage part 150, more the incorporating section i.e. preservation portion 163 by the rear moves.

In addition, food maintaining body 161 arranges the mode of face 162 according to encirclement food, arrange entirely on four limits, in the embodiment 2, food maintaining body 161 is striden food, and that the periphery of face 162 is set is continuous, therefore, as implement mode 2, especially owing to utilize resin to form gabarit, therefore arrange under the situation of the formation that the low food of coefficient of friction of face easily slides for food, follow the switching of pulling out under the situation of multi-direction slip even suppose food, owing to be formed with food maintaining body 161 on whole four limits of food mounting portion, therefore, can suppress to put into the movement of self sliding and causing of food 158, even the reaction that the switching of existence door 121 etc. brings, the heat of putting into food 158 is absorbed by cold-storage spare 150 expeditiously, can suppress to heat up, cool time when shortening food is put into.

In addition, in this class formation that door 121 is pulled out to the freezer outside for drawer type door and container 127, the cold-storage spare 150 that is arranged on container 127 easily is exposed to extraneous air, dewfall and frosting on cold-storage spare 150 increase, the possibility that food slides increases, therefore, the fixed mechanism of embodiment 2 is that the slip inhibition of food of boundary portion 127a, depressed part 160 and food maintaining body 161 is especially effective.

In addition, the 127a of boundary portion that takes in the food maintaining body 161 that the zone possesses and the general freezing zone that does not possess cold-storage spare that possesses cold-storage spare forms smoothly via rake 127b, in other words, can not form the step at right angle in general freezing regional portion, therefore, further reduce the wind path resistance at the flow direction from the cold air of rear side, flow in the zone of taking in that makes cold air can namely possess cold-storage spare 150 swimmingly downstream, do not hinder the structure that cold air forwards flows from the rear of stage portion etc. owing to do not possess, therefore, for example can suppress to produce whirlpool and make from the cold air adverse current of taking in the zone of the food of taking in heat and to the i.e. preservation in freezing zone portion 163 in the flowing of cold air to flow, can further improve cooling effectiveness.

In addition, in the embodiment 2, with respect to the level height 163a of the face of taking in of the preservation portion 163 in the freezing zone of the frozen food 157 in the accommodating container 27, take in the level height 162a that the food of taking in the zone of putting into food 158 arranges the face of taking in of face 162 and be disposed at the high position.Thus, even suppose to put into food putting under the situation of food 158 for the higher food of temperature of face is set, because the air of heat does not flow downwards and flows upward, therefore, arrange at food under the situation of the hot air of face generation, can prevent that heating installation from flowing into to the level height 163a of the face of taking at least of preservation portion 163, can further suppress to put into the heat affecting of the frozen food 157 that 158 pairs of freezing zones of food i.e. preservation portion 163 takes in.

In addition, cold-storage spare 150 can load and unload, and possess the loading and unloading assisted parts 170 that mode that the finger according to user when the place ahead of depressed part 160 loading and unloading cold-storage spare 150 can enter forms at recess, possess loading and unloading maintaining part 171 in recess formation at the container with these loading and unloading assisted parts 170 opposed sides.They be sticked in respectively possesses on cold-storage spare 150, the cold-storage spare loading and unloading assisted parts 172 that forms at recess and the cold-storage spare loading and unloading maintaining part 173 that forms at protuberance, thus, the use sense during loading and unloading is good, and the location can load and unload reliably the time.Namely, cold-storage spare 150 is being installed under the state of depressed part 160, the loading and unloading assisted parts 170 of container 127 sides and cold-storage spare loading and unloading assisted parts 172 constitute connection by recess respectively, thus, user's finger is entered, availability when improving loading and unloading, further, by in the loading and unloading maintaining part 171 that is formed at container 127 sides, inserting cold-storage spare loading and unloading maintaining part 173, when cold-storage spare is installed, can locate reliably, when unloading cold-storage spare, can make these loading and unloading maintaining parts become fulcrum and easily unload cold-storage spare, therefore, can further improve user's availability.

In the embodiment 2, the injection portion that uses when injecting cold-storage liquid in the gabarit container of cold-storage spare forms this cold-storage spare loading and unloading assisted parts 172, therefore, forms cold-storage spare loading and unloading assisted parts 172 with more rational formation.

In addition, link the line 3D-3D of this cold-storage spare loading and unloading assisted parts 172 and cold-storage spare loading and unloading maintaining part 173 by the center line on the left and right directions of cold-storage spare, therefore, the weight of cold-storage spare is not is not roughly loaded and unloaded to the left and right on the bias, therefore, can bring loading and unloading sensation smoothly to the user.

In addition, as shown in Embodiment 2, the arranging of cold-storage spare 150 that is arranged at the container 127 of door 121 highly is 800mm, therefore, the position of door 121 is also near 800mm, it is 500mm～1200mm than the height that is easier to operate that door 121 is positioned at general people, therefore, apply manpower easily, the possibility height of following the reaction of door 121 switching to increase, therefore, the fixed mechanism of embodiment 2 is that the slip inhibition of food of boundary portion 127a, depressed part 160 and food maintaining body 161 is especially effective.

In addition, in the embodiment 2, the supplementary structure that the user stretches into finger when being used for loading and unloading cold-storage spare 150, form loading and unloading assisted parts 170 and cold-storage spare loading and unloading assisted parts 172, in addition, more smooth and easy and keep structure reliably as being used for making loading and unloading, in loading and unloading maintaining part 171, be provided with cold-storage spare loading and unloading maintaining part 173, but not necessarily need to possess both sides, structure according to user's needs and storeroom or cold-storage spare 150, for example, only be suitable for the situation that the supplementary structure only be formed for stretching into finger namely loads and unloads assisted parts 170 and cold-storage spare loading and unloading assisted parts 172, or only be suitable for as being used for making loading and unloading more smooth and easyly and keep structure reliably, in loading and unloading maintaining part 171, be provided with the situation of cold-storage spare loading and unloading maintaining part 173.

In addition, the structure that finger is stretched into as cold-storage spare, in the embodiment 2, load and unload being combined to form of assisted parts 172 by the loading and unloading assisted parts 170 of container 127 sides and the cold-storage spare of cold-storage spare 150 sides, but for example also can consider successfully to load and unload by only possess the loading and unloading supplementary structure of easy seizure finger at cold-storage spare 150.

Equally, more smooth and easy and keep structure reliably as being used for making loading and unloading, in with the loading and unloading maintaining part 171 of container 127 sides as recess structure, be provided with the cold-storage spare loading and unloading maintaining part 173 of cold-storage spare side as the protuberance structure, but these are so long as concavo-convex coincideing then is not limited to this combination.

Container 127 has common shelf space at the rear of protuberance 156 be freezing zone i.e. preservation portion 263.

In container 127, be placed with the frozen food of having preserved 157 and newly put into put into food 158.

In addition, be used for the cool-air feed of refrigerated compartment 107 and vegetable compartment 109 and circulate not shown, but constitute with to possess cold-storage spare and can be set at cool-air feed wind path that the storeroom of cryogenic temperature band cools off mutually independently, different wind path.

Freezer about the present embodiment that constitutes as mentioned above describes its action below.

Cold-storage spare 150 and frozen food 157 are cooled and freeze to namely-20 ℃ of the set points of temperature of refrigerating chamber 108.As shown in Figure 6A, door 121 opened and the food that food 158 is positioned over cold-storage spare 150 of putting into that will be equivalent to 5 ℃ of refrigerated storage temperatures arranges under the top situation of face 259, put into food 158 and take heat by force by the cold-storage spare 150 that freezes to-20 ℃ putting into the back, begin to cool down.At this moment, cold-storage spare 150 is i.e.-20 ℃～-15 ℃ intensifications to the sensible heat territory by heat absorption, and in latent heat territory-15 ℃ maintenance and the temperature difference of putting into food 158, a part is melted simultaneously.In addition, flow into the extraneous air of container 127 also by 150 coolings of cold-storage spare, compare with present freezer, the air in the container 127 can keep low temperature, also can cool off by this Cryogenic air and put into food 158.At this moment, the cold-storage spare material of cold-storage spare 150 257 is i.e.-20 ℃～-15 ℃ intensifications to the sensible heat territory by heat absorption, ℃ are kept for carrying out with the extraneous air of putting into food 158 or flow into the temperature difference of the appropriateness of heat exchange in latent heat territory-15, and a part is melted simultaneously.Not under the situation of cold-storage spare of latent heat type, by putting into the cooling of food 158, on the basis of low temperatureization, follow by the intensification of cold-storage spare and carry out heat exchange, temperature difference reduces, to put into food 158 is cooled to set point of temperature and needs the time, but use the cold-storage spare 150 of latent heat temperature-15 ℃ in the embodiment 4, therefore, carry out heat exchange when the maximum ice crystallization generating zone that freezes correlation of attributes of input food 158 is namely made an appointment with-10 ℃, big temperature difference can be guaranteed, maximum ice crystallization generating zone can be passed through rapidly.In addition, the latent heat temperature is ℃ higher than freezer temperature-20, and therefore, it is poor to guarantee be used to freezing cold-storage spare 150 necessary heat exchange temperature.

In addition, under the situation that door 121 is opened, under the situation of the frozen food of preserving before existing 157,150 coolings of cold-storage spare flow into the extraneous air in the containers 127, compare with present freezer, remain low temperature around the frozen food 157.In addition, compare with present freezer, can suppress to interfere the intensification that causes from the heat of putting into food 158.

Afterwards, as shown in Figure 7, when door 121 is closed, utilize contactless detection device such as infrared ray sensor 280 to detect the temperature of putting into food 158, be certain fixed temperature when above, be judged as and carry out quick-frozen, and the running of beginning freeze cycle (not shown), refrigerant generates cold air to evaporimeter 113 circulations, simultaneously, pressure fan 114 turns round and makes circulating cold air, thus, begins to cool down.Like this, in the embodiment 4, the temperature of utilizing 280 pairs in non-contact detecting mechanism to put into food 158 detects and is fixed temperature when above, begins freezing running automatically.

Thus, cold air 108 is supplied with from refrigerating chamber ejiction opening 153 to refrigerating chamber, rapidly to frozen food 157 and put into food 158 and cool off.At this moment, putting into food 158 cools off by the cold air that ventilates with from the device that the food of cold-storage spare 150 arranges cooling two aspects of face 259.Thus, putting under the higher situation of putting into food 158 of temperature, by carrying out the quick-frozen running automatically rapidly, can prevent to around the temperature effect of the frozen food of preserving in advance 157, the result can prevent other parts of temperature effect of container 127 integral body of refrigerating chamber, therefore, concentrate and utilize cold-storage spare 150 and cold gas two sides to cool off by the food 158 put into that temperature is high, the freezing load of freezer integral body is reduced rapidly, can realize energy-conservation and high-quality freezing preservation.

In addition, the part of cold air also is used in the cooling of cold-storage spare 150.But about the cooling of refrigerating chamber 108, being cooled to than set point of temperature is-20 ℃ high, and therefore, little with the temperature difference of the latent heat temperature-15 of cold-storage spare 150 ℃, cold air mainly is used in the cooling of food.In addition, the ventilation of cold air constitutes to container 127 interior ventilations by not shown ventilation.At this moment, the food of cold-storage spare 150 arranges face 259 and places and cover frozen food 157 and put into food 158, therefore, and mainly to frozen food 157 with put into food 158 and cool off.At this, frozen food 157 and put into food 158 more with the latent heat temperature of cold-storage spare 150 namely-15 ℃ approach, cold air is more many for the component of the cooling of cold-storage spare 150, but, for example, frozen food 157 and putting under food 158 situation for fish or meat, solidification point is near 0 ℃, maximum ice crystallization generating zone mostly is to-10 ℃, in this temperature band, mainly by the major part of cold air to frozen food 157 and put into food 158 and cool off.On the basis of the cooling that this cold air brings, by the cooling from cold-storage spare 150, rapidly by maximum ice crystallization generating zone.

In addition, under the situation that door 121 is opened, container 127 is pulled out from freezer main body 102, when cold-storage spare 150 is exposed in the extraneous air, by cold-storage spare 150, be cooled in the container 127, the temperature that suppresses the frozen food 157 of storage rises, and the extraneous air of putting into of putting into food 158 and flowing into also by 150 coolings of cold-storage spare, freezes at short notice.

The part of the moisture in the extraneous air that the extraneous air when in addition, following door 121 switching flows into is in cold-storage spare 150 dewfall or frosting.Under long situation of the time that next time opens and closes of door 121, distillation or evaporation in the cooling air that utilizes the cooling running to circulate and from the surface removal of cold-storage spare 150, highly humid air is in evaporimeter 113 frostings, circulation by the cooling air in the cooling running as described below, remove moisture and the frost of the surface attachment of cold-storage spare 150, this cooling running circulates the Cryogenic air that has dehumidified once again, and the moisture of cold-storage spare 150 is removed in circulation around cold-storage spare 150.But, carry out at short notice under the situation about next time opening and closing of door 121, namely, cold-storage spare 150 residual owing on once under the state of the moisture that adheres to of the switching of door 121 and frost, open door 121 and put under the situation of food, under the situation of the food lower temperature of especially putting into, put into and close door at 121 o'clock will putting into food 158, because its reaction is put into food 158 and at food easily slip on the face 259 is set.In addition, afterwards, the moisture that exists between this food and the cold-storage spare 150, namely frost or ice since the cooling air be difficult to circulate, therefore be difficult to distil or evaporate, easily residual, under residual state, opened door again at 121 o'clock, its reaction also may make food slide.Like this, even contingency produces and makes cold-storage spare 150 and frozen food 157 and put into the power that food 158 slides and moves to the rear of container 127 owing to the action of the switching of carrying out door 121 in a jumble or continually, cold-storage spare 150 mechanism that is fixed is that the protuberance 156 of container 127 is fixing, therefore, do not move.In addition, prevent cold-storage spare 150 from following the switching of door and mobile fixed mechanism be protuberance 156 to stop to the switching direction of door 121 is that the movement of fore-and-aft direction is purpose, therefore, be that left and right directions is that the mode of length direction forms according to the switching direction right angle orientation with respect to door 121, therefore, can suppress to follow the movement of cold-storage spare 150 of the switching of door 121 more reliably.

In addition, therefore frozen food 157 and put into food 158 and cold-storage spare 150 outstanding absorbent portions 260 and conflict, can prevent that so also from food the rearward preservation of face 259 portion 263 being set moves, and arranges on the face 259 at food and successfully cools off.

In addition, the mark 259a of the central authorities of the mounting part when food arranges face and possesses as the food mounting, for mark 259a, its core is that to be positioned at the switching direction of pulling out that face is set than food be that center line 6C-6C on the fore-and-aft direction is more by rear side to mark center 259b, therefore, even suppose owing to follow the inertia force of the obstruction of pulling out, putting into food 158 has carried out under the mobile situation, even near the food 158 of putting into that is positioned at the mark center 259b moves, also can promote to put into food 158 and be positioned at food face is set.

Like this, about cold-storage spare 150 or frozen food 157 and put into food 158 movement forwards, can prevent the movement of any by the place ahead wall of container 127.Therefore, can freezing-inhibiting food 157 or put into the movement that the slip of food 158 causes, even the reaction that exists the switching etc. of door 121 to bring, frozen food 157 and the heat of putting into food 158 are absorbed by cold-storage spare 50 expeditiously, the cool time in the time of can suppressing to heat up, shorten food and put into.

In addition, in the embodiment 4, the part that this user's finger enters namely loads and unloads assisted parts 170 and cold-storage spare loading and unloading assisted parts 172 arranges according to the mode that is positioned at the right side under the situation of opening the storeroom that possesses cold-storage spare 150 the user.Namely, loading and unloading assisted parts 170 and cold-storage spare loading and unloading assisted parts 172 are formed at the right side of storeroom, therefore, action when general right-handed user loads and unloads cold-storage spare 150 is more smooth and easy, easily assembling can possess the cold-storage spare that can load and unload 150 of the universal design of the usability of having realized considering the user.

In addition, in the embodiment 4, putting under the higher situation of putting into food 158 of temperature, by carrying out the quick-frozen running automatically rapidly, can prevent to around the temperature effect of the frozen food of preserving in advance 157, the result can prevent other parts of temperature effect of container 127 integral body of refrigerating chamber, therefore, concentrate and utilize cold-storage spare 150 and cold gas two sides to cool off by the food 158 put into that temperature is high, the freezing load of freezer integral body is reduced rapidly, can realize energy-conservation and high-quality freezing preservation.

In addition, owing to buying or power supply stop for a long time etc. making under the state that the cold-storage spare material 257 of cold-storage spare 150 melts fully, liquid level is positioned at and is positioned at the absorbent portion 260 that food arranges the top of face 259.Afterwards, by cooling, 257 volumetric expansions of cold-storage spare material are also freezed.The gas 258 that this volumetric expansion is absorbed in the portion 260 absorbs, liquid level is risen and freeze, therefore, food arranges the gas 258 that is difficult to exist the expansion absorption that hinders heat conduction to be used on the face 259, in addition, can reduce the warpage that food that freezing expansion causes arranges face 259, therefore, can successfully keep with frozen food 157 and put into contacting of food 158.That is, absorbent portion 260 is used for absorbing the Volume Changes of the phase change of following heat-storing material.Thus, cooling quick-freezing food 157 and put into food 158 expeditiously, intensification, the cool time when shortening food and putting into that can suppress food.

In addition, be in drawer type door and container 127 this type of the structure of pulling out to the freezer outside at door 121, the cold-storage spare 150 that is arranged at container 127 easily is exposed in the extraneous air, frosting and dewfall at cold-storage spare 150 increase, the possibility that food slides raises, therefore, the slip inhibition of the food on the absorbent portion 260 of embodiment 4 is especially effective.

In addition, as implement mode 4, the arranging of cold-storage spare 150 that is arranged at the container 127 of door 121 highly is 800mm, and therefore, the position of door 121 is also near 800mm, it is 500mm～1200mm than the height that is easier to operate that door 121 is positioned at general people, therefore, apply manpower easily, the possibility height of following the reaction of door 121 switching to increase, therefore, the slip inhibition of the food on the absorbent portion 260 of embodiment 4 is especially effective.

In addition, in the embodiment 4, non-contact detecting mechanism 280 be positioned at the opposed position of mark 259a on, even suppose under inconsistent situation, as long as non-contact detecting mechanism 280 is positioned at the arbitrary place on the perspective plane of above-below direction of center line 6D-6D, when opposite house opens and closes, even food has carried out also can detecting reliably by non-contact detecting mechanism 280 under the mobile situation.Preferably, by making non-contact detecting mechanism possess the middle body of the face that arranges in food, mark 259a possesses in the rear side of food mounting portion, under with the door closing state, on fore-and-aft direction, non-contact detecting mechanism 280 is positioned at the side more on the front than the core 259b of mark 259a, therefore, can imagine following situation, namely, even suppose owing to follow the inertia force of the obstruction of pulling out, put into food 158 and carried out under the mobile situation, be positioned at and put into further side shifting forwards of food 158 near the mark center 259b, therefore, can make and put into the correct detection range that food 158 is positioned at non-contact detecting mechanism 280, can put into the temperature detection of food 158 more accurately, therefore, such formation is also passable.

In addition, cold-storage spare 150 can load and unload, and possess the loading and unloading assisted parts 170 that mode that the finger according to user when the container 127 loading and unloading cold-storage spare 150 can enter forms at recess, possess loading and unloading maintaining part 171 in recess formation via this loading and unloading assisted parts 170 and cold-storage spare 150 at the container of opposition side.They are sticked in the cold-storage spare loading and unloading assisted parts 172 that possesses on cold-storage spare 150 and form at recess and the cold-storage spare loading and unloading maintaining part 173 that forms at protuberance respectively, and thus, the use sense during loading and unloading is good, and the location can load and unload reliably the time.Namely, cold-storage spare 150 is being installed under the state of depressed part 160, the loading and unloading assisted parts 170 of container 127 sides and cold-storage spare loading and unloading assisted parts 172 constitute connection by recess respectively, thus, user's finger is entered, availability when improving loading and unloading, further, by in the loading and unloading maintaining part 171 that is formed at container 127 sides, inserting cold-storage spare loading and unloading maintaining part 173, when cold-storage spare is installed, can locate reliably, when unloading cold-storage spare, can make these loading and unloading maintaining parts become fulcrum and easily unload cold-storage spare, therefore, can further improve user's availability.

In addition, in the embodiment 7, the part that this user's finger enters namely loads and unloads assisted parts 170 and cold-storage spare loading and unloading assisted parts 172 arranges according to the mode that is positioned at the right side under the situation of opening the storeroom that possesses cold-storage spare 150 the user.That is, loading and unloading assisted parts and cold-storage spare loading and unloading assisted parts 172 is formed at the right side of storeroom, and therefore, the action when general right-handed user loads and unloads cold-storage spare 150 is more smooth and easy, easily assembling.

In addition, in the embodiment 7, be that the injection portion that cold-storage spare uses when chatting forms this cold-storage spare loading and unloading assisted parts 172 in the gabarit container of cold-storage spare, injecting cold-storage liquid, therefore, form cold-storage spare loading and unloading assisted parts 172 with more rational formation.

In addition, link the line 14D-14D of this cold-storage spare loading and unloading assisted parts 172 and cold-storage spare loading and unloading maintaining part 173 by the center line on the fore-and-aft direction of cold-storage spare, therefore, the weight of cold-storage spare is not is not loaded and unloaded forwards, backwards on the bias, therefore, can bring loading and unloading sensation smoothly to the user.

In addition, because possessing below heat insulating box 101 and be used for making the castor 151 that freezer main body 102 can easily move and the storeroom that is arranged at the below of refrigerating chamber 108 is vegetable compartment 109, the height dimension till the upper surface of the cold-storage spare 150 that has to the refrigerating chamber 108 is arranged at above ground above 152 the 800mm.

Refrigerating

chamber ejiction opening

153a, 153b are the ejiction openings that ejection is used for the cold air of cooling refrigerating chamber 108, clamping cold-storage spare and about being disposed at.In addition, refrigerating chamber outlet 154 is with the outlet of refrigerating chamber 108 cooled cold air from refrigerating chamber 108 Returning evaporimeters 113.Feed path 155 is passages that the cold air for refrigerated compartment 107 ventilates.

Cold-storage spare 150 is arranged at the bottom of container 127, and the front of cold-storage spare 150 is that the inner face ways of connecting in the place ahead is configured according to door 121 sides with container 127.The back of cold-storage spare 150 is according to outstanding from the bottom of container 127 and prevent that fixed mechanism that cold-storage spare moves up in front and back from being that the front ways of connecting of protuberance 156 is configured, and thus, do not fix movably on fore-and-aft direction.

In addition, cold-storage spare 150 exists cold-storage spare material 257 and gas 258 in airtight resin enclosure.Gas 258 is air.Resin enclosure is that appearance and size is that wide 300mm, depth 300mm, height are the blow molding product of the polyvinyl resin of 20mm, thickness 1.5mm.Cold-storage spare material 257 be lower than the solidification point of general freezing food and than the temperature of maximum ice crystallization generating zone low and than the temperature of refrigerating chamber 108 high temperature namely has the material of latent heat in-15 ℃, charging quantity is held following heat, and this heat has and is equivalent to be arranged at the amount of top volume of food, for example is equivalent to from the latent heat amount of the summation that is equivalent to 30 ℃～-10 ℃ latent heat amount and sensible heat amount.That is, under the situation that cold-storage spare 150 freezes, can not melt fully when putting into normally used general food.

Container 127 has common shelf space at the rear of protuberance 256 be freezing zone i.e. preservation portion 263.

Like this, the upstream side on the wind path of the cold air that flows out from refrigerating

chamber ejiction opening

153a, 153b is the freezer rear side, is formed with the freezing zone of preserving to the frozen food of having preserved 157,

It is the freezer front side that the food mounting portion that puts into food 158 that mounting is newly put into is positioned at the downstream, in the embodiment 7, forms this food mounting portion by cold-storage spare 150.

In addition, the 127a of boundary portion that takes in the food maintaining body that the zone possesses and the general freezing zone that does not possess cold-storage spare that possesses cold-storage spare forms smoothly via rake 127b, in other words, can not form the step at right angle in general freezing regional portion, therefore, can be further reduce the wind path resistance at the flow direction from the cold air of rear side, flowing in the zone of taking in that makes cold air can namely possess cold-storage spare swimmingly downstream, and can not change cold air and forwards flow from the rear of stage portion etc.Therefore, for example, can suppress to produce whirlpool in the flowing of cold air and make self-absorption heat food the cold air adverse current of taking in the zone and flow to the i.e. preservation in freezing zone portion 163, can further improve cooling effectiveness.

In addition, be used for the cool-air feed of refrigerated compartment 107 and vegetable compartment 109 and circulate not shown, but constitute with to possess cold-storage spare and can be set at cool-air feed wind path that the storeroom of cryogenic temperature band cools off mutually independently, different wind path, therefore, for example carry out quick-frozen and a large amount of cold air of bringing can not flow directly into other storeroom.

Freezer about constituting as mentioned above describes its action below.

Namely-20 ℃ of the set points of temperature that cooling promotes the parts cold air cooling that to be cold-storage spare 150 and frozen food 157 namely flow into from refrigerating

chamber ejiction opening

153a, 153b by cooling body and freezes to refrigerating chamber 108.As shown in the figure, door 121 opened and will be equivalent to the food 158 of putting into of 5 ℃ of refrigerated storage temperatures to be positioned over food mounting portion be that the food of cold-storage spare 150 arranges under the situation on the face 259, put into food 158 and after putting into, take heat by force by the cold-storage spare 150 that freezes to-20 ℃, begin to cool down.At this moment, under the big situation of the thermic load of input food 158, cold-storage spare 150 is i.e.-20 ℃～-15 ℃ intensifications to the sensible heat territory by heat absorption, and in latent heat territory-15 ℃ maintenance and the temperature difference of putting into food 158, a part is melted simultaneously.

In addition, flow into the extraneous air of container 127 also by 150 coolings of cold-storage spare, compare with present freezer, the air in the container 127 can keep low temperature, also can cool off by this Cryogenic air and put into food 158.At this moment, the cold-storage spare material of cold-storage spare 150 257 is i.e.-20 ℃～-15 ℃ intensifications to the sensible heat territory by heat absorption, ℃ are kept for carrying out with the extraneous air of putting into food 158 or flow into the temperature difference of the appropriateness of heat exchange in latent heat territory-15, and a part is melted simultaneously.Under this situation, not under the situation of cold-storage spare of latent heat type, by putting into the cooling of food 158, on the basis of low temperatureization, follow by the intensification of cold-storage spare and carry out heat exchange that temperature difference reduces, will put into food 158 and be cooled to set point of temperature and need the time.But be the cold-storage spare 150 of latent heat temperature-15 ℃ in the embodiment 7, therefore, carry out heat exchange when the maximum ice crystallization generating zone that freezes correlation of attributes of input food 158 is namely made an appointment with-10 ℃, can guarantee big temperature difference, can pass through maximum ice crystallization generating zone rapidly.In addition, the latent heat temperature is higher about 5 ℃ than freezer temperature, and therefore, it is poor to guarantee be used to freezing cold-storage spare 150 necessary heat exchange temperature.

In addition, under the situation that door 121 is opened, under the situation of the frozen food of preserving before existing 157, cold-storage spare 150 coolings that are positioned at the place ahead flow into the extraneous air of container 127, compare with present freezer, remain low temperature around the frozen food 157.In addition, compare with the situation that does not have cold-storage spare, can significantly suppress to interfere the intensification that causes from the heat of putting into food 158.

Afterwards, as shown in the figure, when door 121 is closed, utilize contactless detection device such as infrared ray sensor 280 to detect the temperature of putting into food 158, detect under the situation of having put into the food higher than storeroom temperature, be judged as and carry out quick-frozen, and the running of beginning freeze cycle (not shown).And.Refrigerant generates cold air to evaporimeter 113 circulations, and simultaneously, pressure fan 114 turns round and makes circulating cold air, thus, begins quick cooling automatically.Like this, in the embodiment 7, after the temperature of utilizing 280 pairs in non-contact detecting mechanism to put into food 158 detects, begin freezing running automatically.

Thus, 108 supplied with from refrigerating chamber ejiction opening 153a, 153b to refrigerating chamber by the cold gas of evaporimeter 113 cooling, from above-below direction two sides rapidly to frozen food 157 and put into food 158 and cool off.At this moment, the device of putting into this two aspect of indirect cooling that the direct cooling that the heat conduction of the cold-storage spare 150 of food 158 by face 259 is set from food brings and the heat conduction that comes the cold air of self-ventilation bring cools off.Thus, putting under the higher situation of putting into food 158 of temperature, by carrying out quick-frozen running automatically rapidly, the situation that at random begins the quick-frozen running with the user is compared, and can realize freezing under the speed rapidly reliably.In addition, promptly begin the quick-frozen running, and possess cold-storage spare, will put into the downstream that food mounting portion that food puts into is positioned at the cold air that blows out from refrigerating chamber ejiction opening 153a, 153b, therefore, can prevent the temperature effect of frozen food 157 that the preservation portion 263 at the upstream side of cold air is preserved in advance, the result can prevent that the temperature of container 127 integral body of refrigerating chamber or the temperature of the frozen food in the hypomere container from rising.Like this, concentrate and utilize cold-storage spare 150 and cold gas two sides to cool off by the food 158 put into that temperature is high, the freezing load of freezer integral body is reduced rapidly, can realize energy-conservation and high-quality freezing preservation.

In addition, if usually, then in most cases the storeroom of cryogenic temperature band continues the ejection cold gas, and under the situation of having cooled off refrigerating chamber fully, Cryogenic air still can flow, therefore, even under this situation, also the load of cooling off directly can be carried out cold-storage at cold-storage spare superfluously, therefore, in refrigerating chamber, can realize more energy-conservation refrigerating chamber.

In addition, the part of cold air also is used in the cooling of cold-storage spare 150.But about the cooling of refrigerating chamber 108, being cooled to than set point of temperature is-20 ℃ high, therefore, if it is freezing that cold-storage spare 150 carries out when putting at first, then after with cold-storage spare 150 the temperature difference of latent heat temperature-15 ℃ little, cold air mainly is used in the cooling of food.In addition, the ventilation of cold air constitutes to container 127 interior ventilations by not shown ventilation.At this moment, the food of putting into food mounting portion and be cold-storage spare 150 arranges face 259 and is placed with and puts into food 158, therefore, mainly the cold food 158 of putting into is cooled off.At this, put into food 158 more with the latent heat temperature of cold-storage spare 150 namely-15 ℃ approach, cold air is more many for the component of the cooling of cold-storage spare 150, but, for example, frozen food 157 and putting under food 158 situation for fish or meat, solidification point is near 0 ℃, maximum ice crystallization generating zone mostly is to-10 ℃, in this temperature band, mainly by the major part of cold air the cold food 158 of putting into is concentrated cooling.On the basis of this cooling, by the direct cooling that 150 heat conduction from cold-storage spare bring, pass through maximum ice crystallization generating zone rapidly.

In addition, follow the part of the moisture in the extraneous air that the extraneous air of door 121 switching flows in cold-storage spare 150 dewfall or frosting.Under long situation of the time that next time opens and closes of door 121, distillation or evaporation in the cooling air that utilizes the cooling running to circulate and from cold-storage spare 150 surface removals, highly humid air is in evaporimeter 113 frostings, circulation by the cooling air in the cooling running as described below, remove moisture and the frost of the surface attachment of cold-storage spare 150, this cooling running circulates the Cryogenic air that has dehumidified once again, and the moisture of cold-storage spare 150 is removed in circulation around cold-storage spare 150.But, carry out at short notice under the situation about next time opening and closing of door 121, namely, cold-storage spare 150 residual owing on once under the state of the moisture that adheres to of the switching of door 121 and frost, open door 121 and put under the situation of food, under the situation of the food lower temperature of especially putting into, put into and close door at 121 o'clock will putting into food 158, because its reaction is put into food 158 and at food easily slip on the face 259 is set.In addition, afterwards, the moisture that exists between this food and the cold-storage spare 150, namely frost or ice since the cooling air be difficult to circulate, therefore be difficult to distil or evaporate, easily residual, under residual state, opened door again at 121 o'clock, its reaction also may make food slide.Like this, even contingency produces and makes cold-storage spare 150 and frozen food 157 and put into the power that food 158 slides and moves to the rear of container 127 owing to the action of the switching of carrying out door 121 in a jumble or continually, cold-storage spare 150 mechanism that is fixed is that the protuberance 156 of container 127 is fixing, therefore, do not move.In addition, prevent cold-storage spare 150 from following the switching of door and mobile fixed mechanism be protuberance 156 to stop to the switching direction of door 121 is that the movement of fore-and-aft direction is purpose, therefore, be that left and right directions is that the mode of length direction forms according to the switching direction right angle orientation with respect to door 121, therefore, can suppress to follow the movement of cold-storage spare 150 of the switching of door 121 more reliably.

In addition, frozen food 157 and put into food 158 and cold-storage spare 150 outstanding absorbent portions 260 and conflict, therefore, can prevent that so also from food the rearward preservation of face 259 portion 263 being set moves, arrange on the face 259 at food and successfully to cool off, therefore, can cool off fast putting into food 158 more reliably.

In addition, the mark 259a of the central authorities of the mounting part when food arranges face and possesses as the food mounting, for mark 259a, its core is that to be positioned at the switching direction of pulling out that face is set than food be that center line 14D-14D on the fore-and-aft direction is more by rear side to mark center 259b.Therefore, even suppose to put into food 158 and carried out under the mobile situation owing to follow the inertia force of the obstruction of pulling out, put into further side shifting forwards of food 158 even be positioned near the mark center 259b, also can suppress and door 121 collision, promote to put into food 158 and be positioned at food face is set.

In addition, possess non-contact detecting mechanisms 280 such as infrared ray sensor at the wall with food mounting portion opposed top, this non-contact detecting mechanism possesses in food the middle body of face being set.That is, it is back quadrate part on the center line 14D-14D on the fore-and-aft direction that mark 259a possesses in the switching direction of pulling out that food arranges face, and in other words, non-contact detecting mechanism 280 is positioned at the arbitrary place on the perspective plane of above-below direction of center line 14D-14D.Namely, with the core of above-mentioned mark 259a be that mark center 259b as one man arranges on the projection line of above-below direction, under with the door closing state, non-contact detecting mechanism 280 is positioned at the side more on the front than the core 259b of mark 259a at fore-and-aft direction.Therefore, can imagine following situation, namely, even suppose to put into food 158 and carried out under the mobile situation owing to follow the inertia force of the obstruction of pulling out, be positioned at and put into further side shifting forwards of food 158 near the mark center 259b, therefore, can make and put into the correct detection range that food 158 is positioned at non-contact detecting mechanism 280, can put into the temperature detection of food 158 more accurately, further improve rapidly the precision of cooling fast.

Like this, about cold-storage spare 150 or frozen food 157 and put into food 158 movement forwards, can prevent the movement of any by the place ahead wall of container 127.Because, can freezing-inhibiting food 157 and put into the movement that the slip of food 158 causes, even the reaction that exists the switching etc. of door 121 to bring, frozen food 157 and the heat of putting into food 158 are absorbed by cold-storage spare 50 expeditiously, the cool time in the time of can suppressing to heat up, shorten food and put into.

In addition, in the embodiment 7, the part that this user's finger enters is is namely loaded and unloaded assisted parts and cold-storage spare loading and unloading assisted parts 172 and is arranged according to the mode that is positioned at the right side under the situation of opening the storeroom that possesses cold-storage spare 150 the user.Namely, loading and unloading assisted parts and cold-storage spare loading and unloading assisted parts 172 are formed at the right side of storeroom, therefore, action when general right-handed user loads and unloads cold-storage spare 150 is more smooth and easy, easily assembling can possess the cold-storage spare that can load and unload 150 of the universal design of the usability of having realized considering the user.

In addition, in the embodiment 7, putting under the higher situation of putting into food 158 of temperature, by carrying out the quick-frozen running automatically rapidly, can further improve the cooling velocity of putting into food reliably, can prevent to around the temperature effect of the frozen food of preserving in advance 157, the result can prevent other parts of temperature effect of container 27 integral body of refrigerating chamber.Therefore, concentrate and utilize cold-storage spare 150 and cold gas two sides to cool off by the food 158 put into that temperature is high, the freezing load of freezer integral body is reduced rapidly, can realize energy-conservation and high-quality freezing preservation.

In addition, in the embodiment 7, if present freezer, quick-frozen and food temperature are irrelevant usually, carry out the quick-frozen about 150 minutes, and therefore, the situation that increases consumption electric power owing to the quick-frozen that surpasses necessity is more.Among the present invention, after food is put into, with with respect to present freezing about 3 times speed frozen food, utilize infrared ray sensor to detect food temperature, be difficult to make the central temperature-10 ℃ of food deterioration in arrival after, stop freezing and be back to usually freezing, thus, food can deterioration, and carries out necessary quick-frozen, and can be energy-conservation.

Therefore, by finishing of automatic quick-frozen being made as-10 ℃ and be made as than the higher temperature of common cryogenic temperature band, can keep under the state of freezing quality, carry out automatic quick-frozen more energy-conservationly.In addition, should-10 ℃ of central temperatures with respect to common cryogenic temperature band be-20 ℃ high 10 ℃.

Like this, at present, in freezer, adopted freezing function, but its usage frequency is low.As enumerating as this reason, when beginning, quick-frozen need the user to begin to operate, do not know the existence of quick-frozen function self.According to the present invention, can not need the user to begin operation, and make the quick-frozen function operation automatically, therefore, can more promptly carry out the cooling under energy-conservation.

In addition, the present quick-frozen time is roughly necessarily, perhaps is the time that is cooled to the design temperature of storeroom, therefore, although food is frozen, but still carries out excessive cooling running, thereby causes the increase that consumes electric power.The present invention carries out following automatic quick-frozen, namely by possessing the infrared ray sensor that detects food temperature, infer central temperature from the surface temperature of the food that drops into, begin quick-frozen control automatically, if further passed through maximum ice crystallization generating zone then can finish quick-frozen control automatically.Thus, can carry out more energy-conservationly high-quality freezing.

The mixing cooling that two sides of the forced convertion by cold-storage spare and cold air bring, even the cold air in lowest temperature still is approximately the freezing function that realizes having the cooling velocity that equates with the industrial freezer that is refrigerated to-60 ℃ in-40 ℃ the home-use freezer energy-conservationly, can significantly improve the freezing quality of food.

In addition, owing to buying or power supply stop for a long time etc. making under the state that the cold-storage spare material 257 of cold-storage spare 150 melts fully, liquid level is positioned at and is positioned at the absorbent portion 260 that food arranges the top of face 259.Afterwards, by cooling, 257 volumetric expansions of cold-storage spare material are also freezed.The gas 258 that this volumetric expansion is absorbed in the portion 260 absorbs, liquid level is risen and freeze, therefore, food arranges the gas 258 that is difficult to exist the expansion absorption that hinders heat conduction to be used on the face 259, in addition, can reduce the warpage that food that freezing expansion causes arranges face 259.Therefore, can successfully keep and put into contacting of food 158, thus, cooling quick-freezing food 157 and put into food 158 expeditiously.

Like this, about the cold-storage spare material 257 of cold-storage spare 150, the bubble place of accumulating is that absorbent portion 260 is positioned at than food mounting portion instant food and face 259 is set more by above-below direction (on the gravity direction for upper side).Therefore, mounting under the situation of cold-storage spare, enter the cold-storage spare material 257 of inside of cold-storage spare because gravity and mobile downwards, the air that is contained in the gabarit container of cold-storage spare 150 moves to being positioned at the cold-storage spare material 257 that the bubble of upper portion more accumulates the place.Thus, cold-storage spare material with contact with private side that food arranges face 259 opposed gabarit containers, can further improve the heat transfer efficiency that food arranges face 259.

In addition, in this class formation that door 121 is pulled out to the freezer outside for drawer type door and container 127, the cold-storage spare 150 that is arranged on container 127 easily is exposed to extraneous air, dewfall and frosting on cold-storage spare 150 increase, the possibility that food slides increases, therefore, the slip inhibition of the food on the absorbent portion 260 of embodiment 7 is especially effective.

In addition, as implement mode 7, the height of the face that arranges that distance is arranged at the cold-storage spare 150 of the container 127 of door in 121 is 800mm, therefore, also near 800mm, it is 500mm～1200mm than the height that is easier to operate that door 121 is positioned at general people in door 121 position, therefore, automatically the storeroom that carries out quick-frozen is positioned at the most wield position, therefore, can further improve user's usability.The door that is positioned at the people and than the height that is easier to operate is the position of 500mm～1200mm applies manpower easily, the possibility height of following the reaction of door 121 switching to increase, but in the embodiment 7, the food maintaining body absorbent portion 260 that the food that the slip of food causes when suppressing to close moves is especially effective.

Industrial utilizability

As mentioned above, freezer of the present invention can suppress the intensification in the container to be irreducible minimum, and can directly cool off and take in food and guarantee to preserve quality, therefore, is not only home-use freezer, also can be applicable in the purposes such as industrial freezer.
