Simultaneously, the next door 101 that the inner space of kraut refrigerator is divided into left storage compartment 110 and right storage compartment 120 has a pair of communication passage 140 and 150, and described communication passage forms along the horizontal interval each other.Alternatively, communication passage 140 and 150 can vertically be provided with.Built-in electrical deoscillator 141 and 151 is installed in communication passage 140 and 150, and described electrical deoscillator can be operable to and optionally open or close communication passage 140 and 150 respectively.
And as shown in Figure 5, wherein said Fig. 5 shows the schematic block diagram of the cold air EGR of the kraut refrigerator shown in Fig. 3 and 4, and the circulation of control module 170 with the control cold air is set.More particularly, control module 170 receives temperature detection signal from temperature sensor 162 and 163, and output is used to open or close the drive control signal of damper 141 and 151.
For convenient explanation the after this, in these two communication passage, the communication passage that more close evaporimeter 130 is settled is called as first communication passage 140, and with described first communication passage 140 at interval another communication passage of distance to a declared goal be called as second communication passage 150.For the same reason, the damper in first communication passage 140 is called as first damper 141, and the damper in second communication passage 150 is called as second damper 151.
As mentioned above, be formed with left side communication passage 140 and right side communication passage 150 in the next door 101.Thereby left storage compartment 110 and right storage compartment 120 are communicated with by the damper 141 and 151 that is installed in first communication passage 140 and second communication passage 150 respectively alternatively.
Therefore, Current Temperatures in, left storage compartment 110 162 or 163 that detected by temperature sensor or right storage compartment 120 respectively is higher than the situation of the preset temperature that is used for preserve kimchi, damper 141 and 151 is operated, to open first communication passage 140 and second communication passage 150.This allows the cold air in left storage compartment 110 and the right storage compartment 120 to be communicated with each other, this makes that the temperature of inside storage compartments is roughly even, this be by utilize ratio in another storage compartment the colder air of interested storage compartment reduce the temperature in the interested storage compartment realize.Therefore, be embodied as shortened with interested temperature be reduced to default temperature but not operate the refrigerating fan 112 and 122 that is installed in storage compartment 110 and 120 individually by (just as prior art) and reduce the required time quantum of temperature in each storage compartment 110 and 120.
Preferably, EGR also comprises draught fan 142 and 143,152 and 153, and they operationally are installed in the left side and the right side of left side communication passage 140 and right side communication passage 150 on the contrary.Draught fan 142 and 143,152 and 153 helps cold air to circulate more efficiently in left storage compartment 110 and right storage compartment 120.
More preferably, draught fan 142 and 143,152 and 153 is mounted by this way, promptly air from the interior side-blown of communication passage 140 and 150 to the outside.This draught fan 142 and 143,152 and 153 can be realized by the AC fan along a direction blows cold air.
After this, for convenience of explanation, the draught fan on the left inboard of first communication passage 140 is called as first draught fan 142, and the draught fan on the Right Inboard is called as second draught fan 143.Similarly, the draught fan on the left inboard of second communication passage 150 is called as the 3rd ventilation fan 152, and the draught fan on the Right Inboard is called as four-way gas fan 153.
The operation of the cold air EGR that is used for kraut refrigerator according to the present invention will be described with reference to accompanying drawing now.
Fig. 6 and 7 is explanatory views, shows the operation of the cold air EGR that is used for kraut refrigerator according to the present invention.
In operation, the Current Temperatures in left storage compartment and the right storage compartment is detected by the temperature sensor 162 and 163 that is installed in left storage compartment 110 and the right storage compartment 120 respectively.
If determine the preset temperature that Current Temperatures in the right storage compartment 120 is higher than right storage compartment 120 by control module 170, if and the Current Temperatures of also determining in the right storage compartment 120 by control module 170 is higher than the Current Temperatures that is detected by temperature sensor 162, then control module 170 is exported drive control signal, to open first damper 141 and second damper 151, thereby open first communication passage 140 and second communication passage 150 the two, as shown in Figure 6.
Simultaneously, under the control of control module 170, second draught fan 143 and 153 operations of four-way gas fan.Therefore, cold air from left storage compartment 110 flows in the right storage compartment 120 via first communication passage 140, and flow in the left storage compartment 110 via second communication passage 150 from the cold air of right storage compartment 120, thus between left storage compartment 110 and right storage compartment 120 circulate cold air.
The reason of operating second draught fan 143 is, makes cold air blow to the right storage compartment 120 from left storage compartment 110 via first communication passage 140.That is to say that cold air circulates between storage compartment along a kind of like this direction, promptly the cold air in the left storage compartment 110 flows out by communication passage 140 and enters in the right storage compartment 120, and communication passage 140 more close evaporimeters 130 form.
Therefore, near the coldest air that exists the evaporimeter 130 in the inner space of left storage compartment 110 can be directly and is flowed into outright in the right storage compartment 120, thereby has reduced the temperature of right storage compartment 120 more efficiently.
In addition, may be embodied to, the refrigerating fan 112 and 122 that embeds in left storage compartment door 111 and the right storage compartment door 121 turns round together, thereby makes cold air vertically circulate.This has caused the inside storage compartments cold air to circulate more efficiently.
In the aforesaid operations process, if the Current Temperatures of determining in the right storage compartment 120 is lower than preset temperature, then control module 170 control first dampers 141 and second damper 151 are closed, and control second draught fan 143 and four-way gas fan 153 shuts down.
After this, kraut refrigerator 100 allows left storage compartment 110 and right storage compartment 120 to be driven with being mutually independent.
On the other hand, if detecting Current Temperatures in the left storage compartment 110 is higher than the preset temperature of left storage compartment and is higher than Current Temperatures in the right storage compartment 110, then control module 170 is exported drive control signal, opening first damper 141 and second damper 151, thereby open first communication passage 140 and second communication passage 150.
Simultaneously, first draught fan 142 and 152 operations of the 3rd ventilation fan, and therefore, force to blow in the left storage compartment 110 from the cold air of right storage compartment 120 via first communication passage 140, and force to blow in the right storage compartment 120 via second communication passage 150 from the cold air of left storage compartment 110, as shown in Figure 7, circulate cold air thereby between left storage compartment 110 and right storage compartment 120.
Make cold air be from the reason that right storage compartment 120 flows to the left storage compartment 110 via first communication passage 140, near the cold air that exists the evaporimeter 130 in the inner space of right storage compartment 120 can flow in the left storage compartment 110, with thereby reduce the temperature of left storage compartment 110 more efficiently.That is to say that cold air circulates between storage compartment along a kind of like this direction, promptly the communication passage 140 of the cold air in the right storage compartment 120 by more close evaporimeter 130 blows out and enters in the left storage compartment 110.
In addition, can also be embodied as, the refrigerating fan 112 and 122 that embeds in left storage compartment 111 and the right storage compartment 121 turns round together, thereby makes cold air vertically circulate.This has caused the circulation more efficiently of inside storage compartments cold air.
After this, under the control of control module 170, if the temperature of determining in the left storage compartment 110 is reduced to preset temperature, then first damper 141 and second damper 151 are closed, and first draught fan 142 and the 3rd ventilation fan 152 shut down, thereby allow left storage compartment 110 and right storage compartment 120 ground that is mutually independent cooled.
Although illustrated and disclose draught fan 142,143,152 and 153 for being installed in the left side of first communication passage 140 and second communication passage 150 and the AC type fan in the right side, but can replace AC type draught fan with DC type draught fan, wherein said DC type draught fan is suitable for the direction of optionally two-way change air-flow.In this case, be enough to respectively in each of first and second communication passage 140, each DC type draught fan to be installed.
Therefore, in Fig. 6, a DC draught fan that is installed in replacement second draught fan 143 in first communication passage 140 is forced to blow in the right storage compartment 120 from the cold air of left storage compartment 110, the 2nd DC fan that is installed in the replacement four-way gas fan 153 in second communication passage 150 is forced to blow in the left storage compartment 110 from the cold air of right storage compartment 120, thus between left storage compartment 110 and right storage compartment 120 circulate cold air.
Simultaneously, in Fig. 7, a DC draught fan that is installed in replacement first draught fan 142 in first communication passage 140 is forced to blow in the left storage compartment 110 from the cold air of right storage compartment 120, and the 2nd DC draught fan that is installed in replacement the 3rd ventilation fan 152 in second communication passage 150 is forced to blow in the right storage compartment from the cold air of left storage compartment 110, thus between left storage compartment 110 and right storage compartment 120 circulate cold air.
Alternatively, there is the opposite measure of a plurality of installation draught fan mode.An opposite measure is, with draught fan be installed in any one communication passage, for example in first communication passage 140.Draught fan is a DC type fan, and is controlled to optionally the direction along two-way change air-flow.
Another opposite measure is that each AC fan (but not paired AC fan) is installed respectively in each communication passage.
As described, the cold air EGR that is used for kraut refrigerator according to the present invention is provided with first and second communication passage and first damper and second damper, described first and second communication passage are adapted such that left storage compartment and right storage compartment are communicated with each other, and described first damper and second damper are suitable for optionally opening or closing first and second communication passage.Therefore, if the indoor temperature of left storage is higher than preset temperature, then cold air flows to the left storage compartment from right storage compartment, and if the indoor temperature of right storage is higher than preset temperature, then cold air flows to the right storage compartment from left storage compartment.In this mode, the cold air in each storage compartment is recycled more efficiently, thereby the temperature that has shortened cold air is reduced to the required time quantum of preset temperature.
Although illustrated and illustrated the present invention at preferred embodiment, those skilled in the art can know various change and remodeling under the prerequisite of the scope of the present invention that does not break away from claims and limited.
