Via above-mentioned freezing chamber room temperature inductor 162 and chill chamber temperature inductor 164, controller 150 is judged the temperature of freezing chamber 111 and the temperature of chill chamber 112 according to freezing chamber room temperature signal and chill chamber temperature signal.Afterwards, the temperature of the temperature of the freezing chamber 111 of controller 150 foundations and chill chamber 112 is controlled the rotating speed of frozen gas fan 130 and refrigerated gas fan 140.Below will the control mode of controller 150 be described in detail.
In the present embodiment, controller 150 comprises a storage module 152 and a control module 154.Storage module 152 stores a control program.Control module 154 is electrically connected at storage module 152, compressor 122, frozen gas fan 130 and refrigerated gas fan 140.154 pairs of storage modules of control module 152 carry out access and control compressor 122, frozen gas fan 130 and refrigerated gas fan 140 according to the control rule that control program is formulated.Be noted that though controller 150 is made up of a control module 154 and storage module 152 in the present embodiment, such structure is not in order to limit the present invention.In foundation other embodiments of the invention, controller 150 also can be a single electronic circuit that has the chip of programmable functions or have hardware logic electric circuit.Figure 3 shows that the schematic flow sheet of the control rule of the control program that is stored in storage module 152 of the present invention.At first shown in step S1000, start refrigerator 100.After refrigerator 100 is activated, control module 154 reads the control program in the storage module 152, and control rule running according to control program, wherein control default a freezing chamber critical-temperature, one first refrigerating chamber critical-temperature and one second refrigerating chamber critical-temperature in the rule, and freezing chamber critical-temperature＜first refrigerating chamber critical-temperature＜second refrigerating chamber critical-temperature.
Afterwards, shown in step S1002, control module 154 judges whether the temperature of freezing chamber 111 is higher than freezing chamber critical-temperature.If the temperature of freezing chamber 111 is higher than freezing chamber critical-temperature, then shown in step S1004, control module 154 starts compressor 122.Then, shown in step S1006, control module 154 judges whether the temperature of chill chamber 112 is higher than the first refrigerating chamber critical-temperature.If the temperature of chill chamber 112 is higher than the first refrigerating chamber critical-temperature, then shown in step S1008, control module 154 drives frozen gas fan 130 and refrigerated gas fan 140, and makes frozen gas fan 130 and 140 full-speed operations of refrigerated gas fan.Thus, driving via frozen gas fan 130 and refrigerated gas fan 140, the gas of circulation is by evaporimeter 126 and enter freezing chamber 111 and chill chamber 112 via refrigerating chamber first flow 113 and refrigerating chamber first flow 115 respectively in refrigerator 100, so that freezing chamber 111 temperature and chill chamber 112 temperature are reduced to the freezer critical-temperature respectively and below the first refrigerating chamber critical-temperature.
When if the temperature of chill chamber 112 is less than or equal to the first refrigerating chamber critical-temperature, then shown in step S1010, control module 154 is according to control procedure control frozen gas fan 130 and refrigerated gas fan 140, and wherein the running power of frozen gas fan 130 is higher than the running power of refrigerated gas fan 140.For example in the present embodiment, frozen gas fan 130 is with full power operation, and refrigerated gas fan 140 turns round with half-power.Thus, the gas of circulation enters freezing chamber 111 by evaporimeter 126 and via refrigerating chamber first flow 113 in refrigerator 100, so that freezing chamber 111 is reduced to below the freezer critical-temperature.Because refrigerated gas fan 140 is with the half-power running, so refrigerated gas fan 140 can stop the gas that is positioned at chill chamber 112 to be frozen 130 extractions of gas fan to freezing chamber 111.
In step S1002, if the temperature of freezing chamber 111 is less than or equal to freezing chamber critical-temperature, then shown in step S1012, control module 154 close compressor 122.Then shown in step S1014, control module 154 judges whether the temperature of chill chamber is higher than the first chill chamber critical-temperature.If the temperature of chill chamber is less than or equal to the first chill chamber critical-temperature, then shown in step S1016, close frozen gas fan 130 and refrigerated gas fan 140.
In step S1014,, then shown in step S1018, judge further whether the temperature of chill chamber is higher than the second chill chamber critical-temperature if the temperature of chill chamber is higher than the first chill chamber critical-temperature.If the temperature of chill chamber is when being less than or equal to the second chill chamber critical-temperature, then shown in step S1020, start frozen gas fan 130 and refrigerated gas fan 140, wherein the running power of frozen gas fan 130 is lower than the running power of refrigerated gas fan 140.In the present embodiment, frozen gas fan 130 is with the half-power running, and refrigerated gas fan 140 is with full power operation.Thus, the gas of circulation enters chill chamber 112 by evaporimeter 126 and via refrigerating chamber first flow 115 in refrigerator 100.Because frozen gas fan 130 is with the half-power running, so frozen gas fan 130 can stop the gas that is positioned at freezing chamber 111 to be extracted to chill chamber 112 by refrigerated gas fan 140.Be noted that because the temperature of chill chamber 112 is usually above the setting temperature of steam, therefore when control module 154 is carried out step S1020 according to the control rules, the gas by evaporimeter 126 can produce the effect that defrosts to evaporimeter 126.Therefore, step S1020 also can be considered as the step that a pair of evaporimeter 126 defrosts.
In step S1018,, then shown in step S1022, close frozen gas fan 130 and start refrigerated gas fan 140 if when the temperature of chill chamber is higher than the second chill chamber critical-temperature.Thus, the gas that is positioned at freezing chamber 111 is extracted to chill chamber 112 by refrigerated gas fan 140, to reduce the temperature of chill chamber 112.
Except carrying out the defrosting step via above-mentioned control module 154 performed control rules, the present invention can also store a defrosting program in storage module 152, so that control module 154 can be carried out a defrosting rule via reading the defrosting program.In the foundation another embodiment of the present invention, control module 154 can be accepted a control signal, so that control module 154 is carried out the defrosting rule, wherein above-mentioned control signal is sent by a control knob that is disposed on the refrigerator 100.Thus, the user just can directly order about the described defrosting step of control module execution in step S1020 via pushing this control knob.
In sum, since the present invention respectively with frozen gas fan and refrigerated gas fan arrangement in refrigerating chamber first flow and refrigerating chamber first flow, and because controller can be controlled the rotating speed of frozen gas fan and refrigerated gas fan according to the temperature of the temperature of controlling freezing chamber and chill chamber, therefore in terms of existing technologies, the present invention can reach the effect of the mechanical type valve that is equal to prior art via adjusting frozen gas fan and blast that the refrigerated gas fan produced.Because the rotation constantly in the running of frozen gas fan of the present invention and refrigerated gas fan is turned round, therefore in terms of existing technologies, steam is not easy to freeze solidly on frozen gas fan of the present invention and the refrigerated gas fan again.Therefore, the present invention can replace the design of prior mechanical valve, and has more durable advantage.
