Specifically shown in the stereogram of Fig. 4, the refrigeration of high temperature side is provided in vegetable compartment 8 one sides in the place ahead with cooler 13, the freezing of low temperature side is provided in a next side with cooler 14, these refrigerations with and freezing cooler 13,14 across by insulating lid 17 front and back and the row arrangement that form with moulding heat-barrier materials such as foamed styrenes, form cold air path independent of each other, the refrigeration in the place ahead covers with the relatively thinner protecgulum 18 of insulating thickness with the front of cooler 13, and one is formed chiller assembly 19.In addition, in refrigeration with cooler 13 and storeroom---for example under the minimum situation of the temperature difference between the vegetable compartment 8, above-mentioned protecgulum also can not be the lid integral body that is made of so-called insulator, and with the sealing plate formation of synthetic resin plate thickness.

And, being provided with the cold air that cooler is generated above each cooler 13,14 is blown in each storage space and makes the fan 15,16 of its circulation and horn mouth etc., they and above-mentioned chiller assembly 19 formed a side in the refrigerator of back side thermal wall that one set main body, its front EVA (エ バ, ethene-vinyl acetate copolymer) lid 30 covers, cold air is provided for each storage space 11,12 by the running that utilizes freeze cycle like this from cooler, respectively the temperature that they are cooled to be scheduled to.

At this moment, be configured in the freezing refrigeration with cooler 14 and the place ahead at above-mentioned rear and will shunt up and down from the cold air that fan 16 is discharged, form the passing away of sending in top ice-making compartment 6 and temperature exchange chamber 7 and the following refrigerating chamber 9 31 with the insulating lid between the cooler 13 17.And, in a side (left side of Fig. 2) the formed space of the refrigeration that is arranged in the place ahead with cooler 13, formation from ice-making compartment 6 or temperature exchange chamber 7 to freezing with cooler 14 the return flow line or from the return flow line 32 of refrigerating chamber 9 beginnings or make and flow into cold air the vegetable compartment 8 downwards from refrigerating chamber 5 and get back to refrigeration with the return flow line 33 of cooler 13 etc., configuration fan 15 blows out passage 34 with the formed cold air in the back side of refrigerating chamber 5 and is connected above refrigerating with cooler 13.

And, give the refrigerating chamber 9 and the top of foot from freezing Quilt with air conditioning passing away 31 shuntings of discharging with cooler 14 by fan 16, a side who blows to the cold air of top flows into ice-making compartment 6 and promotes ice making, and the opposing party flows into temperature exchange chamber 7 by adjuster 35, indoor temperature cooling is controlled to predetermined design temperature, return refrigerator 14 once more via return flow line 32 at the cooled cold air of each indoor circulation.

Cold air passing away 34 above the Quilt with air conditioning fan 15 that produces in refrigerating with cooler 13 is discharged to, the staggered up and down cold air blow-off outlet 36 that wears is blown in the refrigerating chamber 5 from passage 34, accommodate thing in the cooling chamber, import in the vegetable compartment 8 via passage from the suction inlet of below, circulate with cooler 13 ground getting back to refrigeration after its cooling.

By adopting above structure, set summary longitudinal section partly as shown in Figure 5 as cooler, because the front portion refrigeration that has improved vapourizing temperature is with cooler 13 and the very little temperature difference of existence only between the indoor temperature of the vegetable compartment 8 of an indoor side, therefore can understand as comparing with Figure 18 of the prior art of same section, can be used in and prevent that dewfall or icing insulated room next door from being that the gauge of protecgulum 18 is obviously freezing thin with the insulating thickness between cooler and the vegetable compartment than prior art of insulating thickness A, be specially, the a of Figure 18 needs 70mm in the prior art, and insulating thickness A has 10mm just passable.

At this moment, refrigeration is used and the freezing cooler 13 of using though structure of the present invention is provided with owing to forward lapping, 14 relation, needing new insulating lid 17 between 2 coolers is insulating thickness B (25mm), but reverse side be the back side of refrigerating chamber 5 do not need and prior art and refrigeration with the identical insulating thickness d (10mm) of above-mentioned insulating thickness a that is provided with between the cooler 63, therefore insulating thickness D is 0 substantially, and, the insulating thickness E surface element of refrigerating chamber 5 and atmosphere is not because exist refrigeration cooler 13 herein yet, so can reduce heat-proof quality, attenuate 10mm is 40mm.

And, though refrigeration with and the insulating thickness C of the freezing main body back side one side with refrigerator 13, the 14 backs condition during with prior art be all 70mm mutually, but total amount as above-mentioned reduction, compare the insulating thickness that to cut down about 55mm with prior art constructions, therefore under the state that keeps appearance and size, compare the refrigerator internal volume that can increase about 22L (liter) with the prior art of identical conditions.

The following describes other examples of the present invention.The cooler 13,14 that above-mentioned example is arranged side by side front and back is configured in the back of vegetable compartment 8, but as with same represent shown in Figure 6 of Fig. 5, this example is characterised in that the back that they is configured in refrigerating chamber 9, freezing with cooler 14 as the inboard of the refrigerating chamber of toe lateral across protecgulum 18 ' be provided with, set refrigeration with cooler 13 across insulating lid 17 again.

At this moment, freezing usefulness that front and back are arranged side by side and refrigeration cooler 14, insulating lid 17 between 13 is that insulating thickness B ' is (25mm) same as the previously described embodiments, with the cooler of toe lateral as low freezing of vapourizing temperature with cooler 14, but because indoor corresponding with it is the refrigerating chamber 9 that is cooled to below-18 ℃, therefore the same with the foregoing description between the two exists smaller temperature difference, so cut off the protecgulum 18 of heat leak ' insulating thickness A ' can equally with the foregoing description be 10mm, compare obviously attenuation with cooler with insulating thickness a between the vegetable compartment with the freezing of prior art.

In this example, because the cooler of rear portion side is refrigeration cooler 13, with the temperature difference of atmospheric temperature than freezing little during with cooler, therefore can its insulating thickness of attenuate C ', compare with the foregoing description or prior art example and can reduce 20mm, be 50mm, can obtain heat-proof quality, total reduction is compared and can be reduced to greatest extent with prior art constructions shown in Figure 180, making insulating thickness is 75mm, compares with the prior art constructions of the same terms the refrigerator internal volume to be increased about 27L (liter).

And, as shown in Figure 7, even be configured in indoor front portion with cooler 14 with freezing, refrigeration is used under the situation of cooler with freezing usefulness and refrigeration that cooler 13 is arranged side by side the back that is configured in vegetable compartment 8 with being configured in the rear portion, because the freezing vapourizing temperature with cooler 14 that high vegetable compartment 8 is adjacent with setting room temperature is low, therefore need thickness 70mm same as the prior art as the protecgulum 18 in this a part of insulated room next door " insulating thickness A ", the insulating thickness B that is used for 2 insulation between the cooler " 25mm that needs are same as described above; but because after cooler is refrigeration cooler 13, therefore the insulating thickness C with atmosphere " also can be 50mm.

And, the same with the various embodiments described above, do not need the back side that is arranged on refrigerating chamber 55 of prior art and refrigerate the insulating thickness d (10mm) that uses between the cooler 63, the insulating thickness E at refrigerating chamber 5 back sides is not " because exist refrigeration can reduce heat-proof quality with cooler 13 herein; become 40mm by attenuate 10mm; generally speaking compared with prior art insulating thickness attenuate 15mm can be increased about 10L (liter) with the refrigerator internal volume yet.

If adopt the structure of the various embodiments described above, refrigeration is used and the freezing cooler 13 of using by being arranged side by side accordingly with the storeroom back, 14, and be positioned at the cooler and the corresponding storeroom of toe lateral according to the little relation configuration of temperature difference, can make storeroom and refrigeration and freezing usefulness cooler separately is optimal insulated relation, can reduce the thickness of the outer thermal insulation layer of storeroom inboard or main body, correspondingly can increase the volume of storage space in the refrigerator, and can reduce area with the corresponding cooler of lower-upper length of main body thermal wall 4, under the situation that for example adopts vacuum insulation panel, also can make to set to be of a size of minimum, can reduce material cost and be provided with effectively.

And by freezing usefulness and refrigeration are become assembly with cooler 14,13 composition one, assembling operation or carrying become easily, can improve the efficient of manufacturing or service operation.And, by freezing usefulness and refrigeration are formed one as assembly to the adjuster 34 of each storeroom with the insulating lid parts that form the pipeline that is formed by moulding heat-barrier materials such as foamed styrenes with fan 16,15 or control cold airflow, again with this assembly and above-mentioned freezing usefulness and refrigeration chiller assembly 19 composition one, can integrated each configuration of components, obtain to save the effect in space.

In addition, though in above-mentioned example, refrigerating chamber 5 is configured in topmost, then and row arrangement ice-making compartment 6 and temperature exchange chamber 7, in its lower section dispose vegetable compartment 8, dispose the layout of each storeroom on configuration refrigerating chamber 9 ground, bottom, the present invention is not limited thereto.

The 4th example of the present invention is described below with reference to the accompanying drawings.Fig. 8 is the longitudinal section of refrigerator, and Fig. 2 is its front view.In the following description, for fear of repetition, omitted the part identical with the 1st example.

Since above-mentioned refrigerating chamber 5 accommodate the volume maximum, frequency of utilization is the highest, therefore the pin pivot that is provided with front openings portion both sides props up the door of left and right sides opposite opened, freely close peristome by rotating like this, be configured in following ice-making compartment except that refrigerating chamber 56 and temperature exchange chamber 7, vegetable compartment 8, refrigerating chamber 9 storerooms such as grade are because to accommodate the volumetric ratio refrigerating chamber little and because the height and position of its setting is convenient uses, therefore adopting by the track segment that is provided with on the indoor wall slides the container front and back that remain on the support frame that is fixed on the door, be pulled to outdoorly with the action of opening the door, the mode of the drawing and pulling type door of food is deposited or taken out to opening above container.

As shown in Figure 3, above-mentioned each storeroom is the same as with the 1st example freeze cycle 21 coolings.

In this example, as as between interior case 3 and outer container 2 quencher moiety of the pretreatment stage of foam filled heat-barrier material 4 cross-sectional view as shown in Figure 9, the refrigeration of high temperature side is configured to vegetable compartment 8 one sides of front with cooler 13, the freezing of low temperature side is configured to a next side with cooler 14, these refrigerations are used and are freezing with cooler 13,14 across insulating lid 17 front and back and the row arrangement that form with moulding materials such as foamed styrenes, and the refrigeration of front is provided in from the front with cooler 13 and sees on the right side, back freezing is provided in the side of taking back with cooler 14 and staggers about like this and set.

And, as from than above-mentioned Fig. 9 by the last ice-making compartment 6 and the corresponding above-mentioned cooling fan 15 in the back side of temperature exchange chamber 7, the cross-sectional view of 16 parts, Figure 10 under the state of having filled foamed heat-insulating material 4, as freezing Figure 11 with near the longitudinal section the cooler 14, and as refrigeration with Figure 12 of the longitudinal section of cooler 13 parts can understand such, the refrigeration that is positioned at the place ahead with cooler 13 be configured in than the rear freezing with cooler 14 by under the position on, and use and freezing each cooler 13 with refrigeration, 14 top disposes fan 15 and fan 16 accordingly, generate and rising with cooler 14 by freezing, from the part of the cold gas of the freezing side that sucks later of fan 16 with the front for blowing out side, imported the ice-making compartment 6 and the temperature exchange chamber 7 in the place ahead respectively by adjuster 118, and remaining most of cold air controls to each indoor temperature cooling the temperature of setting from being blown out the refrigerating chamber 9 of passage 129 below being blown in the freezing freezing usefulness that forms previously with cooler 14 by above-mentioned insulating lid 17.

I return flow line 130 that forms in the insulated space of refrigeration with the left side of cooler 13 of cold air by the side setting that takes in ice-making compartment 6 and temperature exchange chamber 7 after the circulation and S return flow line 131 are imported into the freezing freezing suction inlet 132 of using below cooler 14, with the cold air interflow after the circulation in refrigerating chamber 9, get back to freezing with cooler 14.

The cooling of refrigerating space one side is carried out like this: the passage that will rearward extend with the top of cooler 13 from the refrigeration that is arranged at the right side is as the passage 133 of suction fan, cold air is blown out upward from fan 15, blow out the back side passage 135 interior also risings that passage 134 flows into the width formation at the whole back side of traversing refrigerating chamber 5 from refrigerating to use, be blown into blow-off outlet 136 from the refrigeration of the central authorities at top or the back side, back side periphery etc. indoor, with its temperature that is cooled to be scheduled to.

Quilt with air conditioning suction in refrigerating chamber 5 after the circulation forwards tilt to above-mentioned refrigeration and uses the suction passage 137 with the refrigeration that is provided with that blows out passage 134 anteriorly from indoor bottom, switch the V passage 138 that forms in the insulating lid 17 at 7 backs, chamber is imported in the vegetable compartment 8 by temperature, cold air after the circulation cooling vegetable compartment 8 is inhaled into the bottom of refrigeration with cooler 13 from the below of vegetable compartment, then circulation repeatedly.

By adopting above structure, because the cold air that comes out with cooler 13 from refrigeration blows to the top of the same side from the position on the width right side at the back side that set cooler, flow in the back side passage 135, flow in leading to the V passage 138 of above-mentioned refrigeration with the vegetable compartment 8 of the front portion formation of the suction portion of front portion that blows out passage 134 and fan 15 in the circulation back in refrigerating chamber 5, therefore the pressure loss is little, and because the cold air temperature of mutual circulation is close, therefore the thermal insulation layer thickness between can the attenuate adjacent passage becomes effective channel design.

And, refrigeration from said fans 15 to back side passage 135 with blow out passage 134 and refrigeration with suction passage 137 be arranged on integratedly form refrigerating chamber 5 and below ice-making compartment 6, the moulding heat-barrier material 139 of rear portion spaced walls the temperature switching chamber 7, by the pretreatment stage before foam filled urethane foam heat-barrier material moulding heat-barrier material 139 is inserted and is installed to the insulated room next door 10 from the back of interior case 3, not only can guarantee the interval in insulated room next door 10, and easy placed channel 134,137, can positively be fixed on the interior case 3.

By like this back side of vegetable compartment 8 forward lap but about with staggering configuration refrigeration with cooler 13 and freezing with cooler 14, not only reduced temperature effect to each big cooler both sides of vapourizing temperature difference as far as possible, and be arranged side by side above the cooler 13,14 and the corresponding cooling fan 15,16 of each cooler at each, it is opposite each other to make each fan blow out the direction of cold air, and fan 16 is forwards blown out.

Therefore, because the cold air that each cooler is generated flows through corresponding cooling fan 15,16 with good position relation, form freezing usefulness in fan 16 and freezing front and blow out passage 129 with cooler 14, set refrigeration with cooler 13 across insulating lid 17 ground, the thickness of heat-barrier material that therefore can the above-mentioned insulating lid 17 of attenuate.

And, in the refrigeration that is arranged at the front return flow line 130,131 from ice-making compartment 6 and temperature exchange chamber 7 is set in the thermal wall of the side of cooler 13, can prevent to be arranged on indoor obviously the reducing of storeroom internal volume that other places cause of waiting.

As the exploded perspective view of each component parts as shown in Figure 13, above-mentioned refrigeration is formed one with cooler 13 and freezing the freezing of front that covers freezing usefulness cooler 14 that clip with cooler 14 with EVA lid 141 and above-mentioned insulating lid 17, refrigeration covers with EVA lid 142 with refrigeration with the front of cooler 13, constitute EVA assembly 140, this assembly is set to the back in the space that constitutes ice-making compartment 6, temperature exchange chamber 7 and vegetable compartment 8, combines with the line end of the indoor above-mentioned freeze cycle of importing from main body outside.At this moment, because the refrigeration in the place ahead is arranged on freezing with on the low position of cooler 14 than the rear with cooler 13 as mentioned above, so freezing pipe arrangement combination and weld job with cooler 14 tops can easily carry out.

And, by making each cooling fan 15,16 be positioned at the EVA cap assemblies 143 that is provided with each cold air sucting inlet or blow-off outlet and leads to the cold air path of each chamber shown in the exploded perspective view of top ground assembling Figure 14 of cooler 13,14 in this state, just become the state of seeing from the cooler and fan one side of the inside shown in Figure 15, finish the assembling of chiller assembly with the front of the whole assembly of protecgulum 144 coverings.

In addition, 145 is the fan channel components, for not only having formed the horn mouth of cooling fan 15,16, and formed the cold air suction passage and blown out the one assembly of passage, and also be the parts that are assembled into above-mentioned EVA cap assemblies rear portion.

The ice-making compartment 6 of dividing the spaced walls 146 of vegetable compartment 8 and upper chambers and dividing top and the spaced walls of temperature exchange chamber 7 are assembled later in that above-mentioned chiller assembly is assembled into the back side.

Therefore, if employing said structure, when constituting the insulated storage space of refrigerator, the enough foam-in-place modes of energy form the insulated room next door 10 between capacious refrigerating chamber 5 and the nethermost vegetable compartment 8 (refrigerating chamber 9 when being present embodiment), can obtain rigidity as cabinet, can switch the back side picture of chamber 7 and vegetable compartment 8 as shown in Figure 16 as a section be divided into the ice-making compartment 6 and the temperature that form up and down by above-mentioned insulated room next door 10, above-mentioned refrigeration can be used and the freezing cooler 13 of using, 14 and fan 15,16 and the parts that comprise the formation cooler chamber of passage be assembled into one and set this part as EVA assembly 140 or EVA cap assemblies 143, therefore the cooling device parts that a lot of parts groups of former cause not only can be constituted are simplified, can make assembling operation become easy, can be assembled into predetermined position accurately, and can be in the space than broad, carry out each cooler 13 easily and positively, 14 are connected and fan 15 with the pipe arrangement of refrigerating circulation system, 16 electrical connection etc.

And, by being assembled into one as assembly, each being integrated of configuration of components, the effect that can obtain to save the space, and because modularization, transport operation also becomes easily, can improve the efficient of manufacturing or service operation.

Perhaps, by adopting said structure, by disposing the refrigeration that is provided in refrigerating chamber 5 back sides in the prior art with cooler 13 with cooler 14 with freezing, the back side of refrigerating chamber 5 does not need to be provided with the space of cooler, back side passage 135 can use the back side of whole refrigerating chamber 5, therefore, especially the depth size can with the thickness of cooler and cooler and indoor between this gauge of the needed 50mm of thermal wall thickness be compressed to the 15mm that back side passage 135 is set, can obtain needed predetermined air channel cross-sectional area.

Therefore, increase, can increase the volume of refrigerating chamber 5 significantly, in effective internal capacity is large-scale refrigerator about 400L (liter), can increase tens of liters effectively accommodating volume by this gauge that will reduce depth size as refrigerating chamber 5.

And, if adopt the structure of the foregoing description, because the refrigeration that is configured in the front side is vegetable compartment 8 with the front of cooler 13, be the smaller configuration relation of both sides' temperature difference, therefore can make vegetable compartment 8 and refrigeration with and each cooler 13,14 of freezing usefulness be only insulating thickness relation, the heat-barrier material that is formed by foamed styrene etc. that need not be provided with that the surface that prevents protecgulum 144 freezes is only used above-mentioned protecgulum 144 coverings that are made of laminal resin-formed body.Therefore this part does not need the gauge of heat insulating member yet, correspondingly can increase the depth size as vegetable compartment 8, can the expansion chamber in the volume of storage space.

In addition, refrigerated with the influence of cooler 13 grades in the surface temperature of protecgulum 144 and to be reduced, might dewfall or icing situation under, as long as the thermal insulation board of folder one deck thin-walled just can; Perhaps, also can be subjected to drip trays 147, catch the inside that the dew that flows down imports protecgulum 144, flow into the rhone 148 of refrigeration with cooler 13 as below the front of protecgulum 144, forming as shown in Figure 12; And, though not special expression also can set low power heater with cooler 13 1 sides in the refrigeration of protecgulum 144 among the figure, in refrigeration cooling running back energising, not only prevent the dewfall that the high humidity environment in the vegetable compartment 8 causes, can also be used to refrigerate defrosting with cooler 13.

And, as shown in figure 11, refrigeration is tilted accordingly with the inclined plane at the vegetable container 8a back side of setting in the vegetable compartment 8 in the insulating lid 17 of cooler 13 and the inside thereof and the place ahead, therefore, not can because of inclination reduce in the vegetable compartment container (8a) accommodate volume, the longitudinal opening size (A among Figure 11) that can make freezing usefulness blow out passage 129 increases the amount that equates with projected area in the bottom surface.And, can also enlarge the aperture area (B among Figure 11) that freezing suction inlet 132 with cooler 14 is led in conduct below it, can improve the cycle efficieny of cold air in passage.

In addition, though in above-mentioned example, refrigerating chamber 5 is configured in topmost, then and row arrangement ice-making compartment 6 and temperature switch chamber 7, dispose the layout of each storeroom in its underpart configuration vegetable compartment 8, on foot configuration refrigerating chamber 9 ground, the present invention is not limited thereto.
