Abstract

A cold-storage appliance includes at least one insulating container being movable with respect to a supporting structure for opening and closing and comprising a plurality of walls each defining a respective external surface portion; and a cooling means adapted to cool the interior of the closed container. When the container is moved to a closed position, a seal extending around an external surface portion of the container seals that external surface portion against exposure to air moving over the exterior of the container. This helps to control condensation and icing. The appliance may have first and second insulating containers being movable with respect to a supporting structure for opening and closing; and a shared cooling means that supplies cold air via the first container to the second container. This enables a single cooling means to cool both containers.

Description

The improvement of refrigeration or relate to the improvement of refrigeration

Technical field

The present invention relates to use the refrigeration of refrigeration system, comprise the equipment that is used for foodstuff storing and other appearance putrescible thing, for example refrigerating chamber and refrigerating chamber.

Background technology

The present invention has improved the design of describing in the formerly disclosed patent application that the applicant submits to.These early stage patent applications are with WO 01/20237, and WO 02/073104, and WO 02/073105, and WO 02/073107, and WO 2005/024315 and WO 2006/021819 are example.Their content is incorporated in this by reference.

With identical in the early stage patent of applicant, the present invention includes isolated refrigerating equipment, to be used for storing items in cooler environment.The present invention expands to industry, science except fixing household equipment and movably in the application.Yet this specification will be described family or the commercial cold-storage equipment that is used for foodstuff storing especially.

Disclosed equipment has normally drawer shapes of containers in the early stage patent application of applicant, and container seals each other so that the waste of cross pollution, the energy and icing minimizing.For this purpose, each drawer has lid, when closing drawers, and the top of opening wide of lid sealing and closing drawers.The inside of each drawer rather than outside, for example by with the lid evaporimeter or other cooling device that link to each other, and be cooled.

Randomly, can in different compartments, select different temperature adapting to different food or other contents, and adapt to different frozen states, for example a little more than the refrigeration of zero degrees celsius and be significantly less than the freezing of zero degrees celsius.In fact, concerning given compartment, it easily can be changed from the refrigerating chamber to the refrigerating chamber and again conversion return, thereby can in device as a whole, change the ratio in refrigerating chamber space and refrigerating chamber space.In this case, equipment can respond and change the refrigeration demand.

Repeat the introduction of WO 01/020237 briefly, the article that food or other are rotted easily are stored at refrigeration and the state advantage down of isolating is known already: refrigeration retards the degraded of these article, and isolation helps to prevent their cross pollution.Therefore, though be not that often effectively modern refrigerating equipment is refrigerating chamber and refrigerating chamber for example, normally isolated, the user can be with different types of food storage in different compartments thus.All this equipment all have additional purpose: make their energy efficiency maximization.

Invention in the early stage patent application of the present invention and applicant all is to design according to the background of typical refrigerating equipment, and most of typical refrigerating equipments comprise one or more upright cupboards, and each cupboard has the hinged door of sealing vertically in its front portion.Basically the whole inside of cupboard defines storage capacity, and the shelf and the drawer of the food of most of storage capacity by being used to support storage are separated out.Use all shelfs or drawer in the cupboard by opening door.

Cooling unit produces convection loop (convection loop) in cupboard, in cupboard, the air of unit cooling of being cooled descends to the bottom of cupboard, and when described air in its downward flowing during the absorption heat, described air warms and rises and turns back in its cooling unit that is cooled once more, and air is cooled once more in this cooling unit.Can also by in the cupboard or the fan that links to each other with cupboard carry out forced-air circulation.Shelf or drawer are typically made by filament, so that shelf or drawer are to the very little obstruction of circulation generation of air.

The early stage patent application of the present invention and applicant is to upright refrigerating chamber and refrigerating chamber, promptly upright door, and the subject matter of proposition is when door is opened, this makes the cold air that freely flows out cupboard be replaced by that flow at the top, warm surrounding air.The impact that surrounding air pours in the cupboard causes the cupboard internal temperature to rise, so, when compensating described rising, will consume more energy by the operation cooling unit.The surrounding air that enters causes airborne contamination of heavy, and described airborne moisture causes condensation (condensation) and possible freezing in cupboard.Cupboard is opened often more and frequent, and as especially contingent in the commercial cold-storage equipment, these problems are just serious more.

In upright-door arrangements, vertically the limitation of sealing means even when closing the loss of cold air and entering of warm air may take place.Because more intensive than warm slightly air, the coldest air accumulation is exerted pressure in the bottom of cupboard and to the seal interface, unless make that the sealing part forms good sealing between door and cupboard, air will spill.

The early stage patent application of the present invention and applicant has also proposed a plurality of problems intrinsic in the known cabinet type refrigerating chamber, and the cupboard of the open-top of cabinet type refrigerating chamber is typically closed by the horizontally hinged lid of upwards opening.Because so cabinet type refrigerating chamber has directly been got rid of the use of refrigerating chamber superjacent air space, must keep described space, so inconvenience and wasting space so that its lid is opened.Even use lid that slides rather than the lid of upwards opening, article can not be stayed the top of lid easily.Known also have, and big cabinet type refrigerating chamber makes their contents of access extremely difficult, must bend over and move numerous heavy downwards with distressful frozen goods to take article in freezing chamber bottom.

At last, the early stage patent application of the present invention and applicant proposes to separate dissimilar food or other article that rot easily to prevent the problem of cross pollution.In typical refrigerating equipment, the convective principles that is relied on by these equipment and/or force the air principle to damage the separation effect of food.Be designed for the basketry that opens wide basically of the cross-ventilation circulation that promotes between the compartment or the circulation that shelf has also promoted moisture, enzyme and harmful bacteria.In addition, the liquid that any meeting spills or leaks, for example the juice that flows out from uncooked meat can not be contained in the unlimited basketry or shelf.The container that seals in the early stage patent application of applicant has been avoided this point.

In the early stage patent application of applicant, be heat insulation drawer shapes of containers by the heat insulation lid that links to each other with them stacked on top.Lid and drawer replace in piling up.Drawer and their lid can also or be arranged side by side alternatively.Each lid all has the cooling device of himself, and this cooling device is applicable to the inside rather than the outside of the drawer that cooling is connected.In fact, as proposing among early stage patent application WO01/20237 of applicant and the WO 02/073105, can flow in this unit and around the drawer of closing to improve air surrounding environment or heating by setting device.

Simultaneously, when pulling out the lid of closing unlimited top usually fully, each drawer of the early stage patent application of applicant be open-top being used for the content of access drawer, except that the upstanding wall of isolating, each drawer also has heat insulation base plate.Can be exposed to the external temperature of surrounding environment or above-mentioned surrounding environment and can not produce the degree of too much heat gain the time when drawer and lid are heat insulation to them, cover and the base plate and the upstanding wall of drawer must have certain thickness.

And, the early stage patent application of applicant, for example WO 01/20237 and WO 02/073105 have considered between (contemplate) adjacent drawer and a large amount of air gaps between the adjacent lid of drawer and other drawer.The purpose of these air gaps is not just to promoting air to flow, and more particularly the advantageously rapid temperature for the insulating thickness that guarantees to cross over each drawer and lid descends.Otherwise, the outside of drawer or lid may be cooled to below dew point or even be below the freezing point, cause condensation and possible freezing.When the thermal insulation layer of drawer or lid was in close proximity to or touches the thermal insulation layer of adjacent drawer or lid, this was special the risk.In the case, as time goes by, just produced and crossed over the faint temperature of combination thickness that a cooling space is directed to the thermal insulation layer of another cooling space and descend.When opening drawer, as long as the interface is exposed to the air of warm moist, the danger of the interface condensation between the separation layer has just appearred.Therefore in fact, if the temperature at least one cooling space is enough low, interface temperature can be reduced to and be below the freezing point, and any condensation all can cause the formation of icing on the interface.

When refrigerating equipment comprises a plurality of containers and Gai Shi, multilayer insulation and multilayer intermediate air gap will have a negative impact to obtainable refrigerating space in this refrigerating equipment.Be contemplated that the volume maximization that makes the device inside that is divided into thermal insulation layer and air gap, thereby make the available internal capacity maximization that is used to refrigerate, and can not cause cooling space is produced too much heat gain and therefore causes excess energy consumption.Be contemplated that the cooling device quantity that makes in the equipment minimizes, to help space utilization and cost.

Summary of the invention

Design of the present invention is, carries out the periphery sealing around at least one outer surface part of the refrigeration tank of refrigerating equipment.The purpose of sealing is to produce vapour barrier around the surface portion of this container.This air-flow with surface portion and the around container of sealing is isolated, the air-flow around the container may be moisture with pollute, so may increase freezing and deposition pollutant, this pollutant for example is the bacterium on this surface portion.When doing like this, seal allows the surface portion of sealing to be exposed in the colder air (preferably being lower than surrounding environment), and can not be owing to condensation or freezing risk and can be accepted, so reduced the heat gain (heat gain) that enters container via this surface.In fact, have seldom heat insulation local or not heat insulation place in the back of the surface portion of seal, this surface portion can be in the low temperature about the same with contents.

When eliminating or reduce the number of plies of thermal insulation layer and intermediate air gap, equipment can be provided with more refrigerating space for given external volume.

When container was drawer, seal can be the magnetic sliding seal that extends in the loop around the drawer bottom, to be sealed in the top of opening wide of this heat insulation lid or following drawer.Can seal by last drawer, and be sealed in lid or down on the drawer, or by lid or down drawer seal and be sealed in and go up on the drawer.Yet, if do not have drawer and following not lid, perhaps, on the substrate that the equipment that can be sealed in is isolated.

Although it is very preferred, dispensable sealing around the pedestal of drawer.Can also or alternative at drawer the side and/or the rear surface around seal.For example, drawer arranged side by side goes for sealing around their side surface of adjacency.

In a broad sense and from an aspect, the objective of the invention is to a kind of refrigerating equipment, this equipment comprises: the container that at least one is heat insulation, and it can move with respect to the supporting construction that is used to open and close, this container also comprises a plurality of walls, and each wall defines outer surface part separately; And cooling device, be applicable to the inside of cooling off the container of closing; Wherein, when container moved to the closed position, the seal that extends around the outer surface part of container sealed described outer surface part, was exposed to the air outside of mobile this container to prevent described outer surface part.Described air can be the air of ambient air or heating, and the motion of described air can drive by impeller or convection current.

Seal can be connected on the container around relevant outer surface part, to move with container.Alternately, container can move away the seal on the opening, and for example, seal can be fixed with respect to structure.

Preferably, container top opens wide, and when opening with box lunch, keeps cold air.In this case, when container moved to the closed position, heat insulation lid was closed unlimited top suitably.Lid can be fixed on the structure, and cooling device can link to each other with lid.Alternately, when container moves to the closed position, another wall of a container can be closed unlimited top.Other container preferably has heat insulation wall, can be less more heat insulation basically but close the wall at unlimited top than these walls, or in fact not heat insulation.The wall of closing unlimited top can even be run through by one or more holes (aperture).

Generally, the outer surface part of described container or each container can be sealed on the adjacent container of equipment, or is sealed to the covering of adjacent container of equipment, or is sealed on the relative cabinet wall of equipment, or is sealed on the wall on equipment next door.Suitably, adjacent container or lid, perhaps relative cabinet wall, perhaps the wall on equipment next door is heat insulation in the zone with respect to this outer surface part at least.

This container or each container can be cuboidal, so that the outer surface part of sealing is the plane basically.For example, wall of a container can comprise base plate and a plurality of upstanding wall, and described upstanding wall is upright from this base plate, and defines unlimited top jointly.Described upstanding wall can comprise a plurality of sidewalls and a rear wall.Described sidewall can be parallel to each other, and be positioned at the plane that is parallel to the container opening and closing direction of motion.

The outer surface part that is limited by the base plate of upper container can be sealed to relative the covering of the following container of equipment.Replacedly, such outer surface part can sealing around the open-top of container under the equipment.So this base plate can be run through by at least one hole, between upper container and following container, flow to allow air.For fear of the loss of cold air, can operate this hole or each hole of valve gear to close base plate of the unlatching of the arbitrary container of response.

More generally, equipment of the present invention can have first container and second container, and when closing, the refrigerating space of described container communicates.Cold air can be sent to another container from cooling device via a container and use.

The equipment that can be provided with is handled those condensations that may occur in the outer surface part of sealing.For example, the condensation removal duct that links to each other with the outer surface part that seals can be set.This pipe can extend to the inside of container from the outer surface part of sealing, and can close by valve, and when container closure, this valve is opened.When opening container, this valve cuts out to prevent from the cold air of container through pipe and run off.Another selection is the trace heater, to its operation so that the sealing outer surface part warm.This trace heater can move or operation off and on continuously, for example, and only operation when container is opened.

When equipment had first container and second container, described container can be configured to refrigerating chamber and another described container can be configured to refrigerating chamber.In order to keep being approximately the interface temperature of freezing point, what heat insulation between the outer surface part of the sealing of refrigerated container and the refrigerating space can be greater than between the outer surface part of the sealing of cold storage container and the refrigerating space is heat insulation.

In order to open easily, container can be tapered from its direction of opening.For example, container can have upper and lower interface, and arbitrary interface or two interfaces are inclined relative to horizontal.

Container can support by horizontally extending skid, thereby container can move being used for and opens and closes, and supported when closing or open.For example, container can be close and open position between the drawer of translation.Container can also be such drawer, promptly this drawer by rotating with respect to lid around vertical rotation basically close and open position between move, perhaps can also be drum, this drum by rotating with respect to lid around substantially horizontal rotation close and open position between move.

On the other hand, the objective of the invention is to a kind of refrigerating equipment, this equipment comprises: first heat-insulated container and second spacing container, and described container moves with respect to the supporting construction that is used to open and close; And shared cooling device, the inside that is used to cool off first container and second container; Wherein, in use, cold air is fed to second container via first container from cooling device.This makes single cooling device can cool off two containers.Yet first container can be configured to refrigerating chamber and second container can be configured to refrigerating chamber.

First wall of a container suitably comprises at least one pipe or hole, and when first container closure, described pipe or hole link to each other with cooling device, and links to each other with the inside of second container, and the cold air of self-cooling set is transported in second container with future.Cold air can be for example through the refrigerating space of first container and arrive in the refrigerating space of second container.

Cold air can arrive second container by way of first wall of a container.This wall of first container can be separated the refrigerating space of first container and the refrigerating space of second container.Another is set to also have at least one pipe in this wall of first container, this pipe separates with the refrigerating space of first container.This pipe suitably with respect to the thickness horizontal expansion of this wall, for example is fed to cold air the top of opening wide of second container through upstanding wall downwards from cooling device.For this purpose, this pipe can extend to second plenum chamber that is communicated with second container from first plenum chamber around cooling device.When top that second container opens wide during by first container closure, second plenum chamber suitably is arranged on the downside of first container.Second plenum chamber can partly be limited by diffuser.

For heat conducting purpose, this pipe can be positioned at the refrigerating space of distance first container than the position nearer in fact apart from the outside of this container.Therefore, in fact more heat insulation between being provided with between the outside of this pipe and this container than the refrigerating space of this pipe and this container.

Pipe can be more than one, for example, at least one air air supply pipe, it is directed to second container from cooling device, and at least one air return duct, and it is directed to cooling device from second container.When container is opened, run off from pipe for avoiding cold air, sensor can detect arbitrary container and when open.The valve that responds this sensor can stop cold air flowing pipe in this case.

Can cool off first container by heat being conducted into the cold air that cooling device gives out.Conduction may make heat be transmitted to from cooling device and flow to the cold air of second container through at least one inner surface of first container.Conduction can also or selectively through first container and the wall second container adjacency, make heat be transmitted to and be fed in the cold air of second container by cooling device.Conduction can also or the separator between the refrigerating space of the apparatus for supercooling and first container selectively, make heat be transmitted in the cold air that cooling device gives out.This separator can be airtight, so that air that gives out from cooling device and the air in first container are separated, maybe can be packing less, so that the air that gives out from cooling device can flow into first container.

On the other hand, at least one container can be an open-top, and when this container moves to the closed position, is fixed to this structural insulation cover and can closes the top that this opens wide.Cooling device suitably is connected with this.When second container moved to the closed position, the container of second open-top can cut out by first wall of a container, made this wall by suitably sealing around the top of opening wide of second container.

The seal that is used for equipment of the present invention can be to be applicable to the magnetic seal spare that produces sealing gland.They can be sliding seals.

The specific embodiment

Fig. 1 at first with reference to the accompanying drawings (a)～Fig. 1 (e), the freezer unit 10 of two drawer formulas comprises drawer 12 and following drawer 14. Drawer 12,14 is arranged on below the operating surface 16, if do not need supporter, operating surface 16 can be the part of unit 10, or the part of the embedded structure in unit 10.Unit 10 also comprises cupboard 18, and as in the side view that optimally is shown in Fig. 1 (b) and Fig. 1 (c), cupboard 18 is not must be in the embedded installation, and in this was installed, unit 10 centered on by wall or other device.In this case, for example framework can support drawer 12,14 for some other supporting construction.The sidewall of cupboard 10 or other supporting construction, but the flexible skid 20 that the level of support prolongs, thus drawer 12,14 can be drawn back below operating surface 16 and can be supported when opening.

10 front is displaced to a side to control panel 22 in the unit, is set to the front near the last drawer 12 of operating surface 16.This is the convenient height that is used to operate and observe.

The grid 26 of the bottom front of the condenser 24 in the lower room of following drawer 14 by being positioned at unit 10 is discharged heat.The air that grid 26 can also be used for promoting ambient air or heating is in the unit 10 and flow around the drawer 12,14 of closing, as what proposed among early stage patent application WO01/20237 of applicant and the WO 02/073105.

Be shown in Fig. 1 (a) and can be used for the family expenses refrigeration to the unit 10 among Fig. 1 (e) or be used for food service industry, or other commercial application.Last drawer 12 is set to refrigerating chamber usually and plays drawer 14 to be set to refrigerating chamber usually, but if desired, can keep or change these features.For example, how WO 01/20237 has explained that each drawer with many drawer units re-constructs being used for refrigeration or being used for freezingly, so refrigerating chamber space in the unit can arbitrarily change with respect to the ratio in refrigerating chamber space.One or more drawers 12,14 can also have other function, for example quick-frozen or thaw.

Except the recess 28 in the back base angle of the following drawer 14 shown in Fig. 1 (e), this recess protrudes into the inside of this drawer 14, and the profile that Fig. 1 (d) and Fig. 1 (e) show the inner section of each drawer 12,14 in vertical view is rectangle normally.As shown in Figures 2 and 3, this recess provides the space for compressor 30, this compressor 30 back to the following condenser 24 of this play drawer 14 protruding upward.Fig. 1 (d) and Fig. 1 (e) also illustrate the upstanding wall of how to isolate drawer 12,14, and the thermal insulation layer of following drawer 14 is than the heat insulation bed thickness of last drawer 12, to reflect its refrigerating chamber function.

The sectional view of Fig. 2 and Fig. 3 illustrates, and is similar to WO 01/20237, and each drawer 12,14 has heat insulation lid 32, and lid 32 has for example cooling device 34 of evaporimeter, the inside rather than the outside of the drawer of closing 12,14 of described cooling device cooling below.When drawer 12,14 is closed, the seal 36 around the top of opening wide of each drawer 12,14, preferred magnetic seal spare is sealed to drawer 12,14 on the lid 32 that is connected.Still similar to WO 01/20237, the air of surrounding environment is full of the heat insulation side of drawer 12,14 and the heat insulation downside of play drawer 14, freezes and condensation minimizes to remain on by the temperature with their outer surfaces to make more than the dew point.The outside of drawer 12,14 and the downside of following drawer even can heat are as what proposed among the WO 02/073105.Therefore the carriage 20 of this drawer also benefits from the air that is exposed to surrounding environment or heating, need not emit the risk of the corrosion of freezing or being caused by condensate.

Fig. 3 and Fig. 2 difference are that the last drawer 12 of Fig. 2 has heat insulation pedestal 38, and the last drawer 12 of Fig. 3 does not have.In both cases, between the lid 32 of the downside of last drawer 12 and following drawer 14, a small air gap 40 is arranged.If air gap 40 is exposed to freely ambient air flow or is exposed in the heated air stream, the external heat gain that enters each drawer 12,14 inside will be maximum.Yet, can reduce heat gain by temperature in the air gap 40 being reduced to be lower than surrounding environment.Can be by reducing or preventing that the ambient air flow in the air gap 40 from reducing temperature.Just as will be described, although can take measures to handle condensate, the temperature that is reduced in the air gap 40 is just to be reduced on the dew point of surrounding air around, to prevent to form condensation ideally.

The setting of Fig. 2 and Fig. 3 prevents that ambient air flow is through the air gap 40 between the lid 32 of the downside of last drawer 12 and following drawer 14.Therefore, similar with WO 01/20237 and WO 02/073105, the substantial exterior section of last drawer 12 (being its downside in this example) is not exposed in ambient air flow or the heated air stream.For this purpose, on the lid 32 of the downside of last drawer 12 drawer 14 under its peripheral is sealed to.Preferably use magnetic seal spare 42 around the circumference at drawer/lid interface, to produce vapour barrier, when last drawer 12 is closed, thus to prevent to form condensate and icing.

When seal 42 was used on this interface, the thermal insulation layer that is positioned on the pedestal 38 of drawer 12 became unnecessary.Therefore Fig. 3 illustrates the thermal insulation layer that has removed from the pedestal 38 of last drawer 12; Alternatively, thin and firm plastic bottom board 44 supports the contents of going up drawer 12, and when drawer 12 is opened, cold air is remained in the drawer 12.The pedestal of last drawer 12 is sealed directly to down on the heat insulation lid 32 of drawer 14 now.

By the heat gain in the cooling space that reduces to enter drawer 12,14, the embodiments of the invention shown in Fig. 2 and Fig. 3 have all reduced energy consumption.Fig. 3 has additional advantage: owing to do not have thermal insulation layer in the pedestal of drawer 12, so can in last drawer 12, obtain more refrigerating space.The internal depth of the last drawer 12 of Fig. 3 may be darker, compares with the relative more shallow internal depth of the last drawer 12 of Fig. 2.

Being in seal 42 around drawer 12 downsides is reduced to temperature in the air gap 40 to be lower than surrounding environment or even is lower than zero centigrade.When last drawer 12 was opened, the cold relatively horizontal surface (promptly going up the downside of drawer 12 and the upside of lid 32) that is arranged on the interface can be exposed to ambient air.The possibility of result can condensation or freezing on these surfaces, and this depends on the temperature with respect to the ambient air dew point on described surface.Yet in being provided with of Fig. 3, when having thermal insulation layer between air gap 40 and the following drawer 14 as refrigerating chamber, temperature at the interface will approach as the storage temperature in the last drawer 12 of refrigerating chamber (being more than the zero degrees celsius).This has got rid of drawer and has opened the formation of ice afterwards.

After drawer was opened, when condensate appeared on the cold interface surface, these moistures can be inhaled in the drawer 12 by evaporation when last drawer 12 is closed once more.For this purpose, can have permanent ventilating duct (not shown) or valve gear between air gap 40 and the last drawer 12, this valve gear is only just opened when last drawer 12 turns back to the closed position, and when drawer 12 was opened, this valve prevented that cold air from flowing out drawer 12.

Drawer/lid temperature at the interface can further be controlled by trace heating, and described trace heats use and is installed in and only is lower than the heating element heater that covers 32 end face.Such element can use the hot refrigerant of the cooling circuit of outlet unit 10, for example hot gas or liquid coil (liquid line coils).Can also use electrical heating elements.The operation of heating element heater can be depended on opening of drawer, so that only when the risk of condensation maybe needs to evaporate the condensate that may form, just heats.

Embodiment shown in Fig. 4 is similar to the embodiment of Fig. 3, but Fig. 4 illustrates in greater detail seal and cooling device.Same Reference numeral is used for same parts.On the other hand, with lower cover 32 as thermal insulation layer, make in the base plate 44 of drawer 12 can be less with or without thermal insulation layer, to help space efficiency.At this on the one hand, the dark inside of the last drawer 12 among Fig. 4 can be once more with Fig. 2 in the more shallow inside formation of last drawer 12 contrast.

Last drawer 12 among Fig. 4 has four heat insulation upstanding walls 46, and the heat insulation or base plate 44 of (less-insulated) of heat insulation difference basically.When closing, the top of opening wide of last drawer 12 is by loam cake 32 and heat insulation.Peripheral seal 36 between last drawer 12 and loam cake 32 at the interface.

The evaporator fan coil 34 that is arranged on the inclination in the loam cake 32 is positioned at plenum chamber 48, and plenum chamber 48 limits by the recess that this covers 32 downsides, and closes by horizontal subdivision spare 50.When drawer 12 was closed, plenum chamber 48 communicated via the inside of the hole in the separator 50 52 with last drawer 12.Via these holes 52, the convection current of recirculation appears between plenum chamber 48 and the last drawer 12, shown in the arrow among Fig. 4.Separator 50 and hole 52 are spread air-flow from evaporimeter 34.

And heat insulation, peripheral seal 42 links to each other lower cover 32 base plate 44 of last drawer 12 with last drawer 12 by peripheral seal 42.When closing, the top of opening wide of following drawer 14 is by lower cover 32 and by heat insulation.Seal 36 is on the interface between following drawer 14 and the lower cover 32.Following drawer has conventional thermal insulation layer on its four upstanding walls 54 and its base plate 56.When closing, be arranged on the inside of drawer 14 under second evaporimeter, 34 coolings in the lower cover 32.

Therefore, lower cover 32 all provides thermal insulation layer for the top of the bottom of last drawer 12 and following drawer 14.When using three or more drawer, this scheme can repeat repeatedly downwards according to needs.In each case, seal 42 can support to by lid 32 or by drawer 12,14 and be resisted against on the relative sealing surfaces or be resisted against on the relative seal.

Fig. 5 (a) and Fig. 5 (b) illustrate the drawer and the lid structure of biasing, and Fig. 5 (a) illustrates last drawer 12 in the closed position, and Fig. 5 (b) illustrates the last drawer 12 that is shown in an open position.In this was provided with, because the arbitrary or interface, upper and lower 58,60 in interface, top 58 and the lower interface 60 all is inclined relative to horizontal, the above drawer 12 of institute is convergent backward.Although this is provided with the situation that can also be used for only having a magnetic seal spare, the power that this drawer that has reduced two magnetic seal spares of needs opening and closing opposing is set this convergent, wedge shape.

Particularly, when from top view, when promptly observing from the right of Fig. 5 (a) and Fig. 5 (b), the interface, top 58 on every side, the top of opening wide of last drawer 12 is downward-sloping.The lower surface 62 of loam cake 32 correspondingly tilts, to be parallel to the interface, top 58 of drawer 12.When last drawer 12 is closed, the magnetic seal spare (not shown) around the top of opening wide of last drawer 12 will be gone up drawer 12 and be sealed on the connected loam cake 32.Similarly, when from top view, the lower interface 60 of facing the last drawer 12 of lower cover 32 is inclined upwardly.The upper surface of lower cover 32 correspondingly tilts, to be parallel to the lower interface surface 60 of drawer 12.When last drawer 12 is closed, the magnetic seal spare (not shown) between the lower interface 60 of last drawer 12 and the upper surface 64 of lower cover 32 will be gone up drawer 12 and be sealed on the lower cover 32, therefore seal the air gap 40 between last drawer 12 and the lower cover 32.
