The refrigerator of prior art passes through the cyclic processes such as " compression-condensing-expansion-evaporations " as the working fluid of refrigerant, and make refrigerator inside keep low temperature, and make food in the certain hour section, keep fresh device, also be one of daily necessities of people.
The refrigerator of prior art comprises: compressor, condenser, expansion valve and evaporimeter, wherein compressor heats up the refrigerant of low temperature, low pressure, boost into the refrigerant of high temperature, high pressure, condenser will pass through the extraneous gas condensation from the refrigerant that compressor flows into, expansion valve is compared little with the diameter of other parts, and the refrigerant that flows into from condenser reduced pressure, in the inside of evaporimeter, the refrigerant of the expansion valve of flowing through evaporates under low-pressure state, and evaporimeter absorbs the heat of refrigerator inside thus.
Below, structure and the effect to the refrigerator of type side by side of prior art describes with reference to accompanying drawing.
At first, as shown in Figure 1, refrigerator comprises: refrigerating chamber 1 and refrigerating chamber 2, wherein flowing in refrigerating chamber 1 has most of cold air by evaporimeter 4 heat exchanges, the internal temperature of refrigerating chamber 1 maintains about-18 ℃ thus, flow into some cold air by evaporimeter 4 heat exchanges in refrigerating chamber 2, the internal temperature of refrigerating chamber 2 maintains about 0 to 7 ℃ thus.
At this, refrigerating chamber 1 is separated by dividing plate 3 mutually with refrigerating chamber 2.On the top, rear of dividing plate 3 cold air upper port 3a is arranged, flow through the cold air of evaporimeter 4 and heat exchange by the internal feed of cold air upper port 3a to refrigerating chamber 2, have the cold air that is heated up behind the inside of circulation refrigerating chamber 2 to flow into the cold air lower port 3b of the inside of refrigerating chamber 1 again in the bottom of dividing plate 3 respectively.And damper is arranged in the inboard that makes cold air to the cold air upper port 3a of the internal feed of refrigerating chamber, control the cold air that flows into to the inside of refrigerating chamber 2 thus.
Shown in Fig. 2 a, the motor that fan 6 and drive fan 6 are arranged on the top of evaporimeter 4, the cold air that is cooled behind the evaporimeter of flowing through thus will be forced to be recycled to the inside of refrigerating chamber 1, in the front of evaporimeter 4 cold air stream 10 is arranged, cold air stream 10 then forms with the dividing plate mutually that the space is set 7 of evaporimeter 4 by the inner space of dividing refrigerating chamber.
At this moment, phase dividing plate 7 is the two-layer plate structures that constitute with front panel 7b and rear board 7a, and forms cold air stream 10 therebetween.
A plurality of cold gas exhausting outlets 11 are arranged on the front panel 7b of phase dividing plate 7, cold gas exhausting outlet 11 communicates with refrigerating chamber, cold air sucting inlet 13 is in the front panel 7b bottom of phase dividing plate 7, the cold air that is heated up behind the inside of circulating frozen chamber flows on the evaporimeter 4 again by cold air sucting inlet 13, in the bottom, the back side of refrigerating chamber 1 Machine Room 5 is arranged.
The refrigerator of structure as mentioned above, put into 2 li of refrigerating chamber 1 and refrigerating chambers connect power supply under the state of food after, be positioned at compressor in the Machine Room and accept the control signal of control part and drive, and on evaporimeter 4, form heat exchange environment by aforesaid refrigerating circulation system.

At first, the refrigerator of existing structure in refrigerating chamber 1 or refrigerating chamber 2, as long as there is one also not reach temperature requirement, must make compressor and fan continue to drive in order to make its satisfied temperature requirement, has consumed unnecessary electric energy thus.
For example, even if the internal temperature of refrigerating chamber 1 meets the demands, as long as the internal temperature of refrigerating chamber 2 does not also reach temperature requirement, meet the demands for the internal temperature that makes refrigerating chamber this moment, must make compressor and fan continue to drive, unnecessary cold air also can be continued to supply with in the inside that has reached the refrigerating chamber of temperature requirement thus, has therefore caused unnecessary power consumption.
Moreover the refrigerator of existing structure owing to the amount of the cold air that is assigned to refrigerating chamber 2 behind the evaporimeter 4 of flowing through is less, wants slow so compare the cooling velocity of refrigerating chamber 2 with refrigerating chamber 1.
Even if it is higher that the design temperature of refrigerating chamber 2 is compared with refrigerating chamber 1, but because the amount of cold air is less, so the cooling velocity of refrigerating chamber wants slow obviously.

At this moment, refrigerating chamber evaporimeter 4a and refrigerating chamber evaporimeter 4b or polyphone, otherwise in parallel.
And refrigerating chamber is interconnected with cold air stream B with cold air stream A and refrigerating chamber, and also has damper 8 on the position that is interconnected.
And refrigerating chamber all is to be known type heat exchanger in upright arrangement with evaporimeter 4a and refrigerating chamber with evaporimeter 4b.
Simultaneously, the fan on dividing plate 3 205 should make and be accustomed to the use of flow fan.
The refrigerator of type side by side of the first embodiment of the invention of structure is as mentioned above made the explanation of its concrete form and effect.
As shown in Figure 3, Figure 4, the independent cooled refrigerator of first embodiment of the invention is that its left side of benchmark is a refrigerating chamber 1 with dividing plate 3, the right side is a refrigerating chamber 2, on refrigerating chamber 1, have with cold air to refrigerating chamber supply with and the refrigerating chamber of circulation with cold air stream A, have in the inside of dividing plate 3 with cold air to refrigerating chamber supply with and the refrigerating chamber of circulation with cold air stream B.
At this moment, the refrigerating chamber that is separated from each other with cold air stream A and refrigerating chamber with the refrigerating chamber that constitutes refrigerating circulation system being arranged with evaporimeter 4a and refrigerating chamber evaporimeter 4b on the cold air stream B respectively, shown in Figure 11 a and Figure 11 b, refrigerating chamber together constitutes refrigerating circulation system with evaporimeter 4a and refrigerating chamber with evaporimeter 4b and compressor 30, condenser 40 and expansion valve 50.On the refrigerating chamber side, refrigerating chamber uses evaporimeter 4b on dividing plate 3 to refrigerating chamber with evaporimeter 4a.
And, constituting on the phase dividing plate 7 of refrigerating chamber with cold air stream A, facing to refrigerating chamber 1 cold gas exhausting outlet 101 and cold air sucting inlet 103 are arranged respectively, refrigerating chamber cold gas exhausting outlet 201 and refrigerating chamber cold air sucting inlet 203 are also arranged on the face of dividing plate 3 relative refrigerating chambers.
And, identical with existing structure, the fan 105 with the cold air forced circulation is arranged, and fan 105 is an aerofoil fan on refrigerating chamber.Thus, the cold air of refrigerating chamber inside flows to refrigerating chamber evaporimeter 4a by the cold air sucting inlet 103 of phase dividing plate 7 bottoms, and the refrigerating chamber that carries out flowing through after the heat exchange is with cold air stream A, and discharges to refrigerating chamber 1 by the cold gas exhausting outlet 101 on the phase dividing plate 7.
Simultaneously, the fan 205 that the refrigerating chamber of flowing through is carried to refrigerating chamber 2 with the cold air of evaporimeter 4b is arranged on dividing plate 3, and fan 205 should make and is accustomed to the use of flow fan.It is to consider that the gauge of dividing plate 3 is less that fan 205 makes the reason of being accustomed to the use of flow fan.
Thus, the cold air that refrigerating chamber is 2 li flows to refrigerating chamber evaporimeter 4b by the cold air sucting inlet that is formed at dividing plate 3 bottoms, and carries out discharging to refrigerating chamber 2 by the cold gas exhausting outlet on dividing plate 3 tops after the heat exchange.

At this moment, the independent cooled refrigerator of first embodiment of the invention, shown in Figure 11 a, contact mutually on refrigerating circulation system with evaporimeter 4b with evaporimeter 4a and the refrigerating chamber on dividing plate 3 at the refrigerating chamber on the refrigerating chamber, also can be parallel with one another shown in Figure 11 b.
Thus, when two evaporimeters are contacted mutually, the refrigerant of circulating frozen circulation stream at first supplies to refrigerating chamber evaporimeter 4a, after supply to refrigerating chamber evaporimeter 4b on dividing plate 3, this moment, the heat exchange amount on each evaporimeter was decided by factors such as coolant quantity and heat exchange areas.
Simultaneously, when two evaporimeters were parallel with one another, heat exchange amount was decided by the factors such as sendout of refrigerant.
And, refrigerating chamber is interconnected with cold air stream B with cold air stream A and refrigerating chamber, and on the stream C that is interconnected, damper 8 is arranged, this moment is not when a certain indoor temperature meets the demands, damper 8 is opened, make cold air to the not indoor concentrated supply of satisfied temperature requirement, make within a short period of time it reach requirement thus.

At first, after compressor 30 running, on evaporimeter 4a, 4b, form heat exchange environment, and the aerofoil fan 105 used of the refrigerating chamber on refrigerating chamber 1 and refrigerating chamber use be used to flow fan 205 with the cold air forced circulation.At this moment, the cold air of circulating frozen chamber 1 flows to evaporimeter 4a and carries out heat exchange by cold air sucting inlet 103, and then cold air is discharged to refrigerating chamber 1 by cold gas exhausting outlet 101, and circulation again and again.
And, the cold air of circulation refrigerating chamber 2 flows to evaporimeter 4b and carries out heat exchange with cold air sucting inlet 203 by the refrigerating chamber that is formed on the dividing plate 3, then cold air is discharged to refrigerating chamber 2 with cold gas exhausting outlet 201 by the refrigerating chamber on the dividing plate 3, and circulation again and again.
Simultaneously, refrigerating chamber is interconnected with cold air stream B with cold air stream A and refrigerating chamber, and on the stream C that is interconnected, damper 8 is arranged, thus when a certain indoor temperature at first reaches the requirement temperature, damper 8 is opened, making flows through, and meet the demands the cold airflow of side evaporimeter is indoor to what do not meet the demands, therefore cold air is concentrated supply to do not meet the demands indoor after, its temperature can be met the demands within a short period of time.
At this moment, meeting the requirements of the indoor fan earlier needn't work on, so but saves energy.
Therefore, the independent cooled refrigerator of first embodiment of the invention can cool off refrigerating chamber 1 and refrigerating chamber 2 separately respectively with two evaporimeters, so improved cooling effectiveness and reduced power consumption.Meanwhile, as in existing refrigerator, the cooldown rate of refrigerating chamber 2 that will be slow relatively compared with refrigerating chamber 1 its cooldown rate also is improved, and has also maximally utilised the inner space of refrigerator.
Promptly, in the refrigerator of existing structure, need only a certain indoor temperature in refrigerating chamber 1 or the refrigerating chamber 2 and do not reach requirement, then compressor 30 and fan must be continued to drive in order to make it reach temperature requirement, so caused waste of electric energy, but refrigerator of the present invention can make refrigerating chamber 1 and refrigerating chamber 2 cool off separately, event starts damper 8 after the fan that reaches the indoor of temperature requirement is earlier stopped operating, make the indoor cold airflow that meets the demands to the indoor that does not meet the demands, so saved electric energy.
And, the refrigerator of the embodiment of the invention can cool off refrigerating chamber 1 and refrigerating chamber 2 separately, so removed in the prior art refrigerator, the air conditioning quantity that is assigned to 2 li of refrigerating chambers behind the evaporimeter of flowing through is owing to the cooldown rate of the less refrigerating chamber that causes 2 problem points slower than the cooldown rate of refrigerating chamber.
Thus simultaneously, in the present embodiment,,, therefore can increase the internal capacity of refrigerating chamber 1 so can reduce the gauge of the evaporimeter on refrigerating chamber owing to use evaporimeter 4b on dividing plate 3 refrigerating chamber.
According to present embodiment, change existing evaporimeter into two evaporimeters, and, the less evaporimeter 4a of refrigerating chamber 1 special use is arranged being provided with on the position of existing evaporimeter, the special-purpose less evaporimeter 4b of refrigerating chamber 2 is arranged on the dividing plate 3 of refrigerator simultaneously.Therefore, the internal capacity of refrigerating chamber 2 does not change, and has enlarged the internal capacity of refrigerating chamber simultaneously to greatest extent.
