Cold air suction passage 27 comprises the suction inlet 27a on the lowest end back side in each refrigerating chamber Unit 20 of separating by shelf 22; In order to be communicated with suction inlet 27a, be arranged on refrigerating chamber 20 back sides, be communicated with cooling unit room 2, the cold air that sucks refrigerating chamber 20 inside is directed to cooling unit room 2, the suction side vertical pipe 27b that cold air is cooled off by evaporimeter 3 again afterwards.
The refrigerator turn-on power is arranged on refrigerator inside, constitutes the compressor operation of freeze cycle, the gaseous coolant of low temperature, low pressure is compressed into the gaseous coolant of high temperature, high pressure.The gaseous coolant of compressed high temperature, high pressure condenses into the liquid refrigerants of high temperature, high pressure through condenser.The high temperature of condensation, the liquid refrigerants of high pressure convert the liquid refrigerants of low temperature, low pressure to through expansion valve, the liquid refrigerants of low temperature, low pressure converts the gaseous coolant of low temperature, low pressure to through evaporimeter 3 and is evaporated, under the evaporation of evaporimeter 3, ambient air carries out heat exchange, the cooling ambient air produces cold air.
Be forced to air-supply under the rotation of a part by the blowing fan 13 that is arranged on body 1 upper rear portion of the cold air that produces, supply to refrigerating chamber 10 inside, the food of preserving is cooled off the temperature fixed by refrigerating chamber outlet 12a; Remaining cold air is directed to 20 li of refrigerating chambers by discharging side back side pipeline 23d.
Cold air is directed in the discharge side vertical pipe 23c by discharging side back side pipeline 23d, is arranged on the outlet 23a that discharges side horizontal pipe 23b by perforation and is discharged to refrigerating chamber 20 inside, and cold air is free to drop down to the bottom by deadweight.
Be directed to a part of discharging the cold air in the side back side pipeline 23d and be directed in the pipeline 24b of left side by discharging side vertical pipe 23c, the cold air that flow in the pipeline 24b of left side is discharged by outlet 24a, begins cooled interior space successively around left surface; Be directed to a remaining part of discharging the cold air in the side back side pipeline 23d and flow in the pipeline 25b of right side, the cold air that enters in the pipeline 25b of right side is discharged by outlet 25a, begins cooled interior space successively around right flank.Be directed to a part of discharging the cold air in the side back side pipeline 23d back side pipeline 26b by refrigerating chamber 20 back sides and move to refrigerating chamber 20, cold air is discharged equably by the outlet 26a that is evenly distributed on the back side.
Below, describe the process that cold air is discharged by outlet 26a more in detail:
As shown in Figure 5, if move by the pinion 33a and the tooth bar 33b that transmit drive motors 33 driving forces along guide part 32, the opening-closing plate 31 that rotates to left and right side is in intermediateness, left side wall outlet 26c and right side wall outlet 26f maintain the state of opening, left side outlet 26d and right side outlet 26e are in by opening-closing plate 31 closing state, and cold air is only discharged to the wall of refrigerating chamber 20.At ordinary times, discharge to the wall of refrigerating chamber 20 inside by the cold air that back side pipeline 26b discharges, prevent that cold air is in direct contact with on the food, causes the food frostbite.Left side wall outlet 26c and right side wall outlet 26f are always maintained at also not influence under the state of opening.
Thereby sharply rise if pile up the food temperature in the left side of refrigerating chamber 20, as shown in Figure 6, the control part of the temperature inductor S detection signal on the perception left side makes drive motors to rotation counterclockwise, thus rotary opening closing plate 31 to the right.Because opening-closing plate 31 turns an angle to the right along guide part 32, if therefore left side outlet 26d becomes the state of opening, right side outlet 26e is in closing state, left side wall outlet 26c and right side wall outlet 26f discharge cold air, left side outlet 26d also discharges cold air simultaneously, therefore can reduce the in-cabinet temperature that rises in the left side rapidly.
In like manner, thereby if piling up the food temperature on the right side of refrigerating chamber 20 sharply rises, as shown in Figure 7, the control part of the temperature inductor S detection signal on the perception right side makes drive motors rotate to clockwise direction, thus rotary opening closing plate 31 to the left.Because opening-closing plate 31 turns an angle to the left along guide part 32, if right side outlet 26e is the state of opening, and left side outlet 26d is a closing state, and right side outlet 26e also discharged cold air when left side wall outlet 26c and right side wall outlet 26f discharged cold air; Therefore can reduce the in-cabinet temperature that rises on the right side rapidly.
If food is piled up on left side and right side in refrigerating chamber 20 inside, the entire inner space temperature is sharply risen, as shown in Figure 8, the control part of the temperature inductor S detection signal on perception left side and the right side makes drive motors to rotation counterclockwise, thus rotary opening closing plate 31 to the right.If opening-closing plate 31 turns an angle to the right along guide part 32, the intercommunicating pore 31a that connects opening-closing plate 31 is communicated with right side outlet 26e, and left side outlet 26d is also at the state of opening, so left side wall outlet 26c and right side wall outlet 26f discharge cold air; Therefore can reduce refrigerating chamber 20 temperature inside rapidly.If temperature reaches institute below the fixed temperature, make opening-closing plate 31 return to original state, cut off the cold air that left side wall outlet 26c and right side wall outlet 26f discharge.
The cold air that flow into 20 li of refrigerating chambers by each outlet is cooled to the food of refrigerating chamber 20 inside freely to fall after the suitable temperature, gathers in the nethermost unit.And the suction inlet 27a by lower end, refrigerating chamber 20 back side sucks cold air, and the cold air of suction flow into 2 li of cooling unit rooms again by suction side vertical pipe 27b, circulation again after being cooled off again by evaporimeter 3.
