Show, it may include following steps:
Step A: when the first storage room 21 needs cooling capacity, i.e., when the first storage room 21 reaches starting point, make refrigerator
Make the second evaporator of gas flow 32 in the first storage room 21 using the first ducting assembly, exchanges heat with the second evaporator 32
Afterwards, the first storage room 21 is returned.For example, opening the air supply damper 51 and return air damper 52 of the first ducting assembly, unlatching can
Make the second blower 42 (ice making blower) or the first blower 41 (refrigeration blower) of gas circulating flow.It can be according to the first storage room
Real time temperature in 21 judges whether the first storage room 21 needs cooling capacity.
Step B: the temperature of the second evaporator 32 of detection, to judge whether defrost is complete.
Step C: judging whether the first storage room 21 continues need for cooling capacity, and judges that the temperature of the second evaporator 32 is
It is no to be lower than preset temperature.
Cooling capacity is needed in the stopping of the first storage room 21, i.e. the first storage room 21 reaches Burnout, and the second evaporator
When 32 temperature is lower than preset temperature, directly or indirectly return step A.Cooling capacity is continued need in the first storage room 21, and
When the temperature of second evaporator 32 is greater than or equal to preset temperature, D is entered step.
Step D: stopping makes refrigerator evaporate the gas flow second in the first storage room 21 using the first ducting assembly
After device 32, with the heat exchange of the second evaporator 32, the first storage room 21 is returned, that is, closes 51 He of air supply damper of the first ducting assembly
Return air damper 52 and corresponding blower.And the first evaporator 31 is made to provide cooling capacity to the first storage room 21, until the first storing
The stopping of compartment 21 needs cooling capacity, after directly or indirectly return step A.Directly return step A refers to that centre may be not present
Other steps.Return step A refers to that there is also the work steps of other refrigerators for centre indirectly.
In some further embodiments of the invention, as shown in figure 4, the control method of refrigerator further include:
Step E: when ice maker 22 needs cooling capacity, i.e., when ice maker 22 reaches starting point, make the second evaporator
32 provide cooling capacity to ice maker 22.
Step F: when the stopping of ice maker 22 needs cooling capacity, i.e., when ice maker 22 reaches shutdown machine point, stop making
Second evaporator 32 provides cooling capacity to ice maker 22.
Step G: judging whether ice maker 22 needs cooling capacity, and judges whether the first storage room 21 needs cooling capacity.
When ice maker 22 does not need cooling capacity and the first storage room 21 needs cooling capacity, i.e., it is not up to starting point in ice maker 22,
And the first storage room 21 enters step A when reaching starting point.
So far, although those skilled in the art will appreciate that present invention has been shown and described in detail herein multiple shows
Example property embodiment still without departing from the spirit and scope of the present invention, still can according to the present disclosure directly
