Effectively frozen food is thawed in order to realize, in the present embodiment, is also previously provided with corresponding heating
Only condition.During being heated to frozen food, whether real-time or periodic monitor, which currently meets default heating, stops
Condition, when meeting default heating termination condition, controls the heater of closing refrigerator, interrupts the heating process of frozen food.
Alternatively, the default heating termination condition can reach a certain specified temp for the temperature in defrosting room, specifically, the step
Rapid S10 includes：
Step a, when the temperature in the defrosting room reaches the first preset temperature, the heater is closed in control.
In this embodiment, pre-set in having heaters heating process, defrosting indoor temperature rises corresponding default
Temperature.For the ease of description, the preset temperature is hereafter referred to as the first preset temperature.It is understood that the first default temperature
The actual temp value of degree can flexibly be set according to actual conditions, and this is not restricted.
After the heater of refrigerator is opened, the temperature in the defrosting room of refrigerator can be gradually increasing, in this embodiment, real
When or timing detection defrosting room in temperature, for example, detecting the temperature in defrosting room by using temperature sensor.Work as defrosting
When indoor temperature reaches the first preset temperature, judge that first heating cycle terminates, now, heater is closed in control.

Specifically, the step S10 includes：
Step b, when the unlatching duration of the heater reaches the first preset duration, the heater is closed in control.
In this embodiment, the heating cycle for pre-setting having heaters is preset duration.For the ease of describing, hereafter
The preset duration is referred to as the first preset duration.It is understood that the concrete numerical value of first preset duration can be according to reality
Situation is flexibly set, and this is not restricted.
After the heater of refrigerator is opened, timing is carried out to heating duration, for example, when coming by using timer to heating
It is long to carry out timing.It is long when reaching the first preset duration when heated, namely when the unlatching duration of heater reach first it is default when
When long, judge that first heating cycle terminates, now, heater is closed in control.
It will be appreciated by persons skilled in the art that this it is default heating termination condition except can for it is above-mentioned enumerate two
Beyond the mode of kind, it also can also be other modes, not be limited herein.
After heater is closed, due to having frozen food as low-temperature receiver, the temperature in defrosting room can be reduced gradually, and be freezed
Food defrosting must be more thorough, and the temperature in defrosting room can reduce slower, must more thoroughly be thawed conversely, frozen food thaws
Indoor temperature can reduce faster.Therefore, in the present embodiment, freezing food is judged according to the temperature decrease rate in defrosting room
Whether product thaw thoroughly.Specifically, after heater is closed, calculating the temperature after heater closing in defrosting room reduces speed
Rate, for example, calculating the reduction of the temperature in defrosting room by obtaining changing value of the temperature in defrosting room in certain time length
Speed.
Also, in the present embodiment, a scheduled rate threshold value is also previously provided with, the concrete numerical value of the scheduled rate threshold value can
Obtained according to experiment, such as, by many experiments, when frozen food thaws completion, the temperature decrease rate in defrosting room is small
In the scheduled rate threshold value, when frozen food thaws and do not completed, the temperature decrease rate in defrosting room is more than the scheduled rate
Threshold value.
In the present embodiment, when the temperature decrease rate in the defrosting room calculated is less than or equal to the scheduled rate threshold value
When, namely illustrate that the defrosting of frozen food is completed, now, the defrosting mode of operation of closing refrigerator is controlled, recover to normal to run
Pattern.
When the temperature decrease rate in the defrosting room calculated is more than the scheduled rate threshold value, namely explanation frozen food
Defrosting do not complete also, now, control is again turned on heater, carries out second heating cycle, and detailed process such as first adds
Described in heat cycle, just repeat no more herein.
At the end of second heating cycle, heater is closed in control, and calculates the temperature reduction speed in defrosting room again
Rate.If the temperature decrease rate in defrosting room is less than or equal to the scheduled rate threshold value, namely illustrates that the defrosting of frozen food is complete
Into now, the defrosting mode of operation of control closing refrigerator is recovered to normal operation mode.If the temperature reduction speed in defrosting room
Rate is still more than the scheduled rate threshold value, namely the defrosting of explanation frozen food is not completed also, now, above-mentioned behaviour is performed again
Make, carry out next heating cycle, circulate aforesaid operations process, until when the temperature decrease rate in defrosting room is less than default speed
Rate threshold value, now, controls the defrosting mode of operation of closing refrigerator, recovers to normal operation mode.
The scheme that the present embodiment is provided, when needing to thaw to the frozen food in refrigerator defrosting room, starts refrigerator
Defrosting mode of operation, heater is controlled, to carry out heating defrosting to frozen food, until in default heating is met
Only during condition, heater is closed in control, the temperature decrease rate in defrosting room after heater closing is then calculated, if thawing
Indoor temperature decrease rate is more than scheduled rate threshold value, illustrates that the defrosting of frozen food is not completed also, now, then secondary control is opened
Heater is opened, proceeds heating to frozen food and thaws, circulation is performed to be operated above, until the temperature reduction speed in defrosting room
Rate is less than scheduled rate threshold value, illustrates that the defrosting of frozen food is completed, now, defrosting mode of operation is closed in control.So as to realize
The defrosting to frozen food can just be completed by being not required to Weight metering device, therefore, reduce the cost of refrigerator.
Further, as shown in figure 4, proposing the control method second embodiment of refrigerator of the present invention based on first embodiment,
In the present embodiment, the step S20 includes：
Step S21, when the closing duration of the heater reaches the second preset duration, obtains working as in the defrosting room
Preceding temperature；
Step S22, calculates the temperature gap of first preset temperature and the Current Temperatures；
Step S23, calculates the temperature gap divided by the quotient of second preset duration, and the quotient thaws to be described
Indoor temperature decrease rate.
In this embodiment, in addition to the first preset duration described in first embodiment, also it is previously provided with
Two preset durations, such as, pre-set second preset duration for 30 minutes.Also, it is to be understood that, this second it is default when
Long concrete numerical value can flexibly be set according to actual conditions, and this is not restricted.
After heater closing, duration is closed to heater and carries out timing, for example, equally using timer come to heater
Close duration and carry out timing.When the closing duration of heater reaches the second preset duration, the Current Temperatures in detection defrosting room,
For example, detecting the Current Temperatures obtained in defrosting room by using temperature sensor.When getting the Current Temperatures in defrosting room
Afterwards, the temperature gap of the first preset temperature and Current Temperatures is calculated, then by the temperature gap divided by the second preset duration, is calculated
The quotient of gained is the temperature decrease rate in defrosting room.For example, it is assumed that the first preset temperature is T1, the defrosting room got
Interior Current Temperatures are T0, and the second preset duration is t2, then can be calculated the temperature reduction speed in defrosting room after heater is closed
Rate v size is：V=(T1-T0)/t2.
Alternatively, in addition to can be by calculating the temperature decrease rate in defrosting room with upper type, it can also lead to
Other modes are crossed to calculate the temperature decrease rate in defrosting room.For example, in another embodiment, the step S20 includes：
Step c, monitoring the temperature in the defrosting room, to be reduced to the second preset temperature institute from first preset temperature right
Answer after duration；
Step d, calculate first preset temperature and second preset temperature temperature gap divided by it is described after when
Long quotient, the quotient is the temperature decrease rate in the defrosting room.
In another embodiment, and it is not required to set the second preset duration, but pre-sets the second preset temperature, its
In, second preset temperature is less than the first preset temperature.After heater closing, the temperature in defrosting room is gradually reduced, in solution
During the indoor temperature of jelly is gradually reduced, the temperature in monitoring defrosting room is reduced to the second default temperature from the first preset temperature
Degree it is corresponding when being reduced to the second preset temperature after duration, namely temperature of the monitoring in defrosting room, corresponding to heater
Closing duration.For example, it is assumed that the first preset temperature is T1, the second preset temperature is temperature in T2, monitoring defrosting room from the
One preset temperature T1 be reduced to corresponding to the second preset temperature T2 after when a length of t0, then can be calculated heater close after solve
The size for freezing indoor temperature decrease rate v is：V=(T1-T2)/t0.
Further, in order to ensure the accuracy of the temperature decrease rate in the defrosting room obtained by calculating, in the present embodiment,
The step a includes：
Step a1, when the temperature in the defrosting room reaches first preset temperature, is controlled in the defrosting room
Temperature maintains first preset temperature；
Step a2, when the temperature in the defrosting room maintains first preset temperature and reaches three preset durations,
The heater is closed in control.
Further, in the present embodiment, when the temperature in defrosting room reaches the first preset temperature, do not control immediately
Heater is closed, but the temperature that the temperature in control defrosting room is maintained in the first preset temperature, namely control defrosting room is steady
It is fixed.After temperature stabilization in defrosting room, then control to close heater.Alternatively, corresponding 3rd preset duration is pre-set,
When temperature in defrosting room maintains the first preset temperature and reaches three preset durations, heater is closed in control.For example, defrosting room
When interior temperature reaches the first preset temperature, the temperature in control defrosting room maintains the first preset temperature, starts simultaneously at timing,
When timing reaches three preset durations, namely temperature in defrosting room maintains the first preset temperature and reaches the 3rd preset duration
When, heater is closed in control.Because the temperature in defrosting room reaches stabilization, so that subsequently calculating the temperature drop in defrosting room
Low rate is more accurate, and then improves the accuracy thawed to frozen food.
If for example, as shown in figure 5, the 3rd preset duration is t3, the first preset temperature is T1, the second preset temperature is T2,
After the temperature in defrosting room, which rises, reaches the first preset temperature T1, it is T1 in the first preset temperature to control the temperature in defrosting room
It is t3 to maintain the 3rd preset duration, and the temperature that then control is closed in heater, defrosting room is gradually decrease to the second preset temperature
For T2.
The scheme that the present embodiment is provided, after control heater carries out heating defrosting to frozen food, works as defrosting room
When interior temperature reaches the first preset temperature, first control the temperature in defrosting room to maintain the first preset temperature and reach that the 3rd presets
Duration, it is ensured that the temperature stabilization in defrosting room, then control to close heater, so that the temperature decrease rate subsequently calculated is more
Plus it is accurate, and then improve the accuracy thawed to frozen food.
Further, the control method the 3rd for proposing refrigerator of the present invention based on first embodiment or second embodiment is implemented
Example, in the present embodiment, after the step S20, in addition to：
Step e, according to the temperature decrease rate of calculating, and default frozen food weight and temperature decrease rate
