Description
The present invention relates to a kind of refrigerator, particularly have the refrigerator that can optionally use the refrigeration system of one of cooling chamber.
Usually, refrigerator has two cooling chamber housings of formation and produces the refrigeration system of cooling off air and being supplied to cooling chamber.Cooling chamber comprises refrigerating chamber that keeps low temperature and the refrigerating chamber that keeps a little higher than freezer temperature.
Refrigeration system comprises that the compressor, condensation of compression refrigerant are by the condenser of the refrigerant of compressor compresses with by making the refrigerant gasification in the condenser produce the evaporimeter that cools off air.Thereby the cooling air that evaporimeter produces has fan to blow supplies with refrigerating chamber and refrigerating chamber.
Because conventional refrigerator has two cooling chambers, i.e. refrigerating chamber and refrigerating chamber, it is different that temperature wherein will keep.An amount of cooling air dispersion must be arranged to refrigerating chamber and refrigerating chamber and hold them in required temperature.Yet, in refrigerator, be difficult to the cooling air that evaporimeter produces suitably is distributed to refrigerating chamber and refrigerating chamber with an evaporimeter.
In order to overcome this shortcoming, developed the refrigerator of using so-called independent cooling method.In the refrigerator of using the independent cooling method, be provided with two refrigeration systems of corresponding refrigerating chamber and refrigerating chamber.Refrigeration system is controlled independently of each other, so that respectively to refrigerating chamber and the required cooling air of refrigerating chamber supply.
Yet, in the refrigerator of this application independent cooling method,, just need refrigeration system be installed and and then manufacturing cost be improved in bigger space because each refrigeration system all comprises compressor, condenser and evaporimeter.Therefore, this independent cooling method can be applied to the refrigerator of large volume and can not be used for the refrigerator of small size or medium volume.
In order to address the above problem, as shown in Figure 3, developed the refrigerator that adopts a compressor and two evaporimeters.
With reference to Fig. 3, compressor 103, condenser 104, first evaporimeter 101 are connected successively with second evaporimeter 102, and form a loop in the refrigeration system of this conventional refrigerator.First evaporimeter, 101 corresponding refrigerating chambers, second evaporimeter, 102 corresponding refrigerating chambers.
The refrigerant of compressor 103 compression is by cold or cool off not enough condenser 104 and supply with first evaporimeter 101.The refrigerant of supplying with gasifies in first evaporimeter 101, correspondingly, produces the cooling air around first evaporimeter 101.The cooling air that produces is blown by the refrigerating chamber fan and supplies with refrigerating chamber.
Subsequently, the refrigerant that flows out first evaporimeter 101 is supplied with second evaporimeter 102.First evaporimeter, 101 remaining compression refrigerants gasify in second evaporimeter 102, correspondingly, produce the cooling air around second evaporimeter 102.The cooling air that produces is blown by the refrigerating chamber fan and supplies with refrigerating chamber.
Yet in this conventional refrigerator, the amount of the cooling air that first evaporimeter 101 produces can be adjusted by control compressor 103, and the amount of the cooling air that second evaporimeter 102 produces can not be adjusted.That is to say that the amount of the cooling air that second evaporimeter 102 produces depends on remaining air supply in first evaporimeter 101, so the amount of the cooling air that second evaporimeter 102 produces is determined by the vaporization ability of first evaporimeter 101.Because refrigerating chamber can remain on temperature required that the user sets, and refrigerating chamber can not remain on required temperature, the food in the refrigerating chamber may be crossed cold or the cooling deficiency.
In addition, in this conventional refrigerator, another shortcoming person of being to use can not optionally be freezed to one of cooling chamber.Therefore, if the cooling chamber of no cooling chamber and use cools off together in vain, just influenced the effect of institute's consumed power.
The present invention is intended to solve above-mentioned the problems of the prior art, the object of the present invention is to provide a kind of refrigerator that can carry out the selectivity cooling to the cooling chamber that the user mainly uses, thereby avoids no cooling chamber cooling and the minimizing power consumption.
Another object of the present invention is to provide a kind of refrigerating chamber that can prevent to cross refrigerator cold or that cooling is not enough.
For achieving the above object, the invention provides a kind of refrigerator, have the housing that forms first and second cooling chambers; The compressor of compression refrigerant; Condensation is by the condenser of the refrigerant of compressor compresses, and this refrigerator comprises: first and second evaporimeters of corresponding first and second cooling chambers of difference, and first and second evaporimeters are connected in series between condenser and compressor; From the bypass pipe of the branch location bifurcated between first and second evaporimeters, be used to shunt the refrigerant that flows out from first evaporimeter, thereby make refrigerant by bypass pipe circulation and supply compressor; Be installed in the switch valve of branch location, be used for the refrigerant that flows out from first evaporimeter is optionally supplied with second evaporimeter and bypass pipe.
Herein, the cooling chamber of corresponding first evaporimeter is a refrigerating chamber, and the cooling chamber of corresponding second evaporimeter is a refrigerating chamber.
Between the outlet of second evaporimeter and the described bypass pipe check valve is set preferably.Check valve branch refrigerant refluxes, and makes the refrigerant by the bypass pipe circulation can not be back to second evaporimeter.
According to the present invention, can only cool off the cooling chamber that the user mainly uses.Therefore, can avoid another no cooling chamber unnecessarily to cool off and reduce electric energy loss.
In addition, when two cooling chambers use simultaneously, can avoid cooling chamber to cross cold or the cooling deficiency by the gauge tap valve.

Fig. 1 is the sectional view of refrigerator of the present invention, and Fig. 2 is the block diagram of the refrigeration system that adopts in the refrigerator of Fig. 1.
Refrigerator of the present invention has housing 10 that forms two cooling chambers 11 and 12 and the refrigeration system that produces the cold air of supplying with cooling chamber 11 and 12. Cooling chamber 11 and 12 comprises the refrigerating chamber 11 that keeps low temperature and keeps being higher than the refrigerating chamber 12 of the temperature of refrigerating chamber 11.On refrigerating chamber 11 and refrigerating chamber 12, be separately installed with the door 13 and 14 that is used for switch.
Refrigeration system comprises the compressor 3 of compression refrigerant, and condensation is by the condenser 4 of compressor 3 compression, produces two evaporimeters 1 and 2 of cold air by the refrigerant gasification that makes condensation in the condenser 4.First evaporimeter, 1 corresponding refrigerating chamber 11, the second evaporimeters 2 corresponding refrigerating chambers 12.The cold air that first evaporimeter 1 and second evaporimeter 2 produce is blown by refrigerating chamber fan 15 and refrigerating chamber 16, so that supply with refrigerating chamber 11 and refrigerating chamber 12 respectively.
Simultaneously, bypass pipe 6 is told from tube connector 21.Bypass pipe 6 interconnects tube connector 21 and circulation pipe 23.Switch valve 5 is installed in the position of tube connector 21, i.e. the branch location told of bypass pipe 6.Switch valve 5 is generally 3 logical valves, and the user can control it by unshowned console switch, perhaps preferably can control automatically by unshowned control part.The effect of switch valve is that the refrigerant that flows out from first evaporimeter 1 is supplied with second evaporimeter 2 and bypass pipe 6.
In addition, check valve 7 is installed on the circulation pipe 7, i.e. the outlet of close second evaporimeter 2.Check valve 7 makes refrigerant only flow through circulation pipe 23 in a direction.More particularly, by check valve 7, refrigerant can flow to compressor 3 from second evaporimeter 2, and refrigerant can be blocked by check valve 7 to flowing of second evaporimeter 2 from bypass pipe 6.
Below the process of refrigerastion that refrigerator of the present invention is finished will be described.
By refrigerant condensation in condenser 4 of compressor 3 compressions, supply with first evaporimeter 1 subsequently.Refrigerant gasifies in first evaporimeter 1, thereby produces cold air around first evaporimeter 1.Cold air is blown by refrigerating chamber fan 15 so that supply with refrigerating chamber 11, thus the food that stores in the cooling refrigerating chamber 11.
The cold air that flows out from first evaporimeter 1 flows into second evaporimeter 2 by tube connector 21.Remaining compression refrigerant gasifies in second evaporimeter 2 in first evaporimeter 1, and produces cold air around it.Cold air is blown so that supply with refrigerating chamber 12 by refrigerating chamber fan 16, thereby makes the food cooling that stores in the refrigerating chamber 12.The cold air that flows out from second evaporimeter 2 flows into compressor 3 by circulation pipe 23.
If the user only wants to use refrigerating chamber 11, he can pass through console switch (not shown) console switch valve 5.Subsequently, the refrigerant that flows out from first evaporimeter 1 is supplied with bypass pipe 6 by check valve 5.The cold air of supplying with bypass pipe 6 arrives compressor 3 by circulation pipe 23 first motions.In this case, can avoid refrigerant to be back to second evaporimeter 2 by check valve 7 from bypass pipe 6.
As mentioned above, when user's driving switch valve 5, prevent that refrigerant from supplying with second evaporimeter 2, therefore, the Quilt with air conditioning that is fed to refrigerating chamber 12 blocks.Thereby the user can only use refrigerating chamber 11.
In addition, when only adopting refrigerating chamber 11, according to the temperature that the user sets, refrigerating chamber 12 can be used as refrigerating chamber 12 and uses.If promptly the user is set at the typical temperature of corresponding refrigerating chamber 12 with the temperature of required refrigerating chamber 11, the food that is stored in refrigerating chamber 11 can be not freezing and be only refrigerated.
In addition, even the user uses refrigerating chamber 11 and refrigerating chamber 12 simultaneously, also can prevent refrigerating chamber 11 and refrigerating chamber 12 cold excessively or cooling deficiencies by suitable gauge tap valve 5.In this case, the temperature of refrigerating chamber 11 is controlled by the running of compressor, and the temperature of refrigerating chamber 12 is by switch valve 5 controls.Promptly, if when first evaporimeter 1 and second evaporimeter 2 all produce cold air, refrigerating chamber 12 cools off and when reaching required temperature fully, by gauge tap valve 5 refrigerant of supplying with second evaporimeter 2 is blocked can prevent refrigerating chamber 12 cross cold or cooling not enough.If the temperature of refrigerating chamber 11 raises, gauge tap valve 5 and cold air is supplied with refrigerating chamber 12 again once more.
As mentioned above,, can only cool off the cooling chamber that a user mainly uses, thereby avoid the cooling of no another cooling chamber and reduce power consumption according to the present invention.In addition, can avoid the cold or cooling deficiency of mistake of cooling chamber.
