The present invention relates to the refrigerator field.
Background technology
In general, refrigerator is that circulating frozen is repeatedly carried out in the compression-condensing-expansion-evaporation that utilizes refrigerant, with refrigerator inside low temperatureization, makes food keep freshness within a certain period of time, can be described as one of necessary article in the daily life.
The circulating frozen structure of this refrigerator comprises: compressor reducer, condensed device, expansion valve, evaporimeter.The compressor reducer refrigerant of low temperature/low pressure can be heated up/boosts into the refrigerant of high temp/high pressure; Condensed device can be condensing by the extraneous air cooling from the refrigerant that compressor reducer flows into; Expansion valve forms the diameter more small than other parts diameter, can make the refrigerant decompression that flows into from condensed device; Evaporimeter can make the refrigerant by expansion valve evaporate in low-pressure state, absorbs the temperature in the storage space.
Below, explanation has the structure and the effect of refrigerator arranged side by side now with reference to appended drawings:
Fig. 1: the stereogram of current refrigerator structure.
Fig. 2 a: the profilograph of I-I line among Fig. 1.
Fig. 2 b: the drawing in side sectional elevation of current refrigerator structure.
As shown in Figure 1, the refrigerator zoning is refrigerating chamber and two parts of refrigerating chamber.Refrigerating chamber can carry out the cold air heat exchange by evaporimeter 4, and therefrom most of cold air flow in the storage space, and temperature in the storage space is remained on-18 ℃; Refrigerating chamber then carries out the cold air heat exchange by evaporimeter 4, and therefrom a part of cold air flow in the storage space, and temperature in the storage space is maintained at about 0-7 ℃.
Refrigerating chamber 1 and refrigerating chamber 2 are to utilize dividing plate 3 to separate, the upper back of dividing plate 3 is provided with cold air through hole 3a, the cold air of the heat exchange that evaporimeter 4 can be carried out is fed to refrigerating chamber, and the bottom of dividing plate 3 is provided with cold air through hole 3b, the cold air that heats up after the refrigerating chamber circulation can be flow back into refrigerating chamber again.For making cold air be transported to refrigerating chamber in right amount, the inboard of cold air through hole 3a is provided with the damper that control cold air flow into refrigerating chamber 2.
Shown in Fig. 2 a, the top of evaporimeter is provided with arrives the fan 6 of refrigerating chamber 1 and the motor of drive fan with the cold air forced circulation through the evaporimeter cooling, and the cold air path of evaporimeter 4 fronts is to be formed with the dividing plate mutually 7 that evaporimeter 4 spaces are set by the storage space of separating refrigerating chamber.
Phase dividing plate 7 is to be formed by front panel 7a and rear board 7b two-ply structure, and the centre can be formed with cold air path 10.
Most cold gas exhausting outlets 11 that communicate with refrigerating chamber are arranged on the front panel 7a of phase dividing plate 7, the bottom of the front panel 7a of phase dividing plate 7 is formed with the circulating frozen chamber and is flow into the cold air sucting inlet of evaporimeter again by the cold air that heated up, and refrigerating chamber 1 lower rear then is provided with Machine Room 5.
The refrigerator that constitutes with said structure is as connecting power supply under the situation that food is housed in refrigerating chamber 1 and refrigerating chamber 2, the compressor of Machine Room will start after receiving the signal of controller, and by circulating frozen, evaporimeter will constitute heat exchange environment simultaneously.
Cold air by evaporimeter 4 carries out the heat exchange cooling with evaporimeter, discharges to the cold air path 10 of refrigerating chamber side by the rotation of fan.Most of cold gas exhausting outlet 11 that passes through flows into to refrigerating chamber 1 in the cold air, and fraction flows into to refrigerating chamber 2 by cold air through hole 3a.The cold air that passes through the circulation of refrigerating chamber 1 and refrigerating chamber and heated up will flow into to evaporimeter 4 by cold air sucting inlet once more, and formation can be carried out the cold air circulating structure of heat exchange.
As mentioned above, the refrigerator of prior art has taken a lot of spaces because of what the evaporimeter 4 that is arranged on refrigerating chamber phase dividing plate 7 rears there is no need, so the volume of the storage space of refrigerating chamber 1 also will reduce.
In other words, not only wide but also high evaporimeter is arranged on the rear wall side of refrigerating chamber, and what there is no need has taken a lot of spaces, and the storage space volume of refrigerating chamber 1 is reduced, and therefore just can not effectively utilize the usage space of refrigerator.
