Reference numeral 11 is the formula that such as the splits around door of the front-surface side opening portion for opening and closing refrigerating chamber 8, and Reference numeral 12 is the drawer type door of refrigerating chamber 9, and Reference numeral 13 is the drawer type door of vegetable compartment 10.
Reference numeral 16 is for being arranged on the evaporimeter in cold air distributor chamber 15, this cold air distributor chamber 15 is positioned at the rear side of refrigerating chamber 9, be formed at and have between the backplate 9a be made up of resin material of refrigerating chamber blow-off outlet 14 and interior case 3, Reference numeral 17, for being arranged on the pressure fan above evaporimeter 16, circulates to refrigerating chamber 8, refrigerating chamber 9 and vegetable compartment 10 for making the cold air having carried out heat exchange at evaporimeter 16.In addition, although not shown, the rear side of vegetable compartment 10 is provided with compressor.
As shown in Figure 3, Figure 4, Reference numeral 18 is refrigerating chamber pipeline that be located at the central portion of the width of resin material 5 along interior case 3, that be communicated with cold air distributor chamber 15, this resin material 5 be located at the refrigerating chamber 8 be made up of resin material backplate 8a and between top board 8b and interior case 3, the above-below direction of refrigerating chamber 8 is provided with the multiple refrigerating chamber blow-off outlets 19 to refrigerating chamber 8 opening, refrigerating chamber in ceiling portion, with on pipeline 18, is provided with the refrigerating chamber blow-off outlet 19a of forward face side opening.
As shown in Figure 3, Figure 4, Reference numeral 20 is for returning wind path, i.e. the 1st refrigerating chamber cold air backflow pipeline, it is arranged along backplate 8a in the close mode being located at the side of the width of the resin material 5 between the top board 8b of refrigerating chamber 8 and interior case 3, run through the 1st spaced walls 6, and the rear side of refrigerating chamber blow-off outlet 19a in ceiling portion, be communicated with a pair suction inlet 21a, the 21b (following, to be sometimes only denoted as 21) of the both-side opening at top board 8b.
Reference numeral 22 is bottom surface opening at refrigerating chamber 8 and the 2nd refrigerating chamber cold air backflow pipeline be communicated with the 1st refrigerating chamber cold air backflow pipeline 20 by the 1st spaced walls 6, and Reference numeral 23 is to be communicated with the 1st refrigerating chamber cold air backflow pipeline 20 and to the vegetable compartment pipeline of vegetable compartment 10 cool-air feed.In addition, refrigerating chamber pipeline 18 and the 1st refrigerating chamber cold air backflow pipeline 20 front and back near ceiling portion intersects.
Reference numeral 24 is for being located at the 2nd spaced walls 7 and making the refrigerating chamber cold air backflow pipeline that refrigerating chamber 9 is communicated with cold air distributor chamber 15, and Reference numeral 25 is for being located at the 2nd spaced walls 7 and making the vegetable chamber cold air reflux line that vegetable compartment 10 is communicated with cold air distributor chamber 15.
In the refrigerator of the present embodiment formed as described above, the cold air having been carried out heat exchange by evaporimeter 16 is supplied to refrigerating chamber 9 by pressure fan 17 from the blow-off outlet 14 of refrigerating chamber 9, and via the refrigerating chamber pipeline 18 be communicated with cold air distributor chamber 15, blow out from the refrigerating chamber blow-off outlet 19 of backplate 8a and the refrigerating chamber blow-off outlet 19a that is located at ceiling portion of being located at refrigerating chamber 8, cool in refrigerating chamber 8 equably thus.
The warm air being trapped in the top of refrigerating chamber 8 is inhaled into from suction inlet 21a, 21b of being located at both sides, ceiling portion by the cold air pushing from refrigerating chamber blow-off outlet 19,19a blowout, by the 1st refrigerating chamber cold air backflow pipeline 20, collaborate at the 1st spaced walls 6 place and the cold air of the low temperature flowing into the 2nd refrigerating chamber cold air backflow pipeline 22, be fed into vegetable compartment 10 by vegetable compartment pipeline 23 afterwards, cool vegetable compartment 10 thus.
On the other hand, be fed into refrigerating chamber 9 and the cold air cooled in refrigerating chamber 9 is returned from the refrigerating chamber cold air backflow pipeline 24 being located at the 2nd spaced walls 7 to the bottom of the evaporimeter 16 of cold air distributor chamber 15, in addition, the cold air cooled vegetable compartment 10 returns from the vegetable chamber cold air reflux line 25 being located at the 2nd spaced walls 7 to the bottom of the evaporimeter 16 of cold air distributor chamber 15.Like this, the air turning back to the temperature of cold air distributor chamber 15 slightly high utilizes evaporimeter 16 to be again cooled, afterwards as described above at refrigerator Inner eycle.
In the refrigerator of the present embodiment formed as described above, the 1st refrigerating chamber cold air backflow pipeline 20 that suction inlet 21a, 21b of arranging with the both sides in the ceiling portion at refrigerating chamber 8 are communicated with runs through the part from the ceiling portion of refrigerating chamber 8 to the 1st spaced walls 6, therefore, the heat had due to the opening and closing of door 11 or the food of storage, the heat from heat source of refrigerating chamber 8 and from outside entering etc. of heat and can not be stirred with cold air by the air in the refrigerating chamber 8 that heats, but extruded by the cold air from refrigerating chamber blow-off outlet 19,19a blowout and return from refrigerating chamber 8.
On the other hand, the 1st refrigerating chamber cold air backflow pipeline 20 extends through the 1st spaced walls 6 from the ceiling portion of refrigerating chamber 8, and the pressure loss therefore in refrigerating chamber 8 becomes large.If the pressure loss becomes large, from the amount minimizing of the cold air that refrigerating chamber blow-off outlet 19,19a blow out to refrigerating chamber 8, desired temperature can not be cooled to by refrigerating chamber 8.
Therefore, in the present embodiment, be provided with the 2nd refrigerating chamber cold air backflow pipeline 22,2nd refrigerating chamber cold air backflow pipeline 22 is at the bottom opening of refrigerating chamber 8, run through the 1st spaced walls 6 and be communicated with the 1st refrigerating chamber cold air backflow pipeline 20, therefore, it is possible to reduce the pressure loss in refrigerating chamber 8, the air quantity blowing out cold air to refrigerating chamber 8 can be guaranteed, therefore, it is possible to the temperature on the top of refrigerated compartment 8 efficiently.
In addition, backplate 8a, the top board 8b etc. of refrigerating chamber 8 are formed by resin material, therefore less with the difference of environment temperature, even if therefore contact with them at the cold air of refrigerating chamber with circulation in pipeline 18, and also can not the surface sweating, icing of plate 8a, top board 8b overleaf.
In addition, even if the air that the temperature of circulation is slightly high in the 1st refrigerating chamber cold air backflow pipeline 20 contacts with backplate 8a, top board 8b, due in the 1st refrigerating chamber cold air backflow pipeline 20 temperature of air of circulation and the difference of environment temperature little, so the possibility that backplate 8a, top board 8b do not freeze.In addition, the heat exchange of backplate 8a etc. can be reduced by thus, therefore, it is possible to prevent cooling effectiveness from reducing.
As described above, refrigerator according to the present embodiment, can start side by side to suck from suction inlet 21a, 21b of the both sides, top being located at refrigerating chamber 8 warm air lodging in top with the cooling of refrigerating chamber 8, therefore, it is possible to make warm air and cold vapor-phase replacement and accelerate cooling velocity, energy-saving can be promoted thus.
