It is actually needed and is configured.Each room of refrigerator can arrange one or more temperature sensor, alternatively,
When between one, indoor exist multiple temperature sensor, the temperature that multiple temperature sensors collect can be taken
The temperature of this room it is set as after average.
After refrigerator is opened, between Preset Time passes through between indoor preset temperature sensor detection refrigerator
Room temperature, alternatively, the compartment temperature that continuous multiple time points acquire can be stored by refrigerator,
So that the compartment temperature of the compartment temperature of current point in time with a upper time point is compared.When this is default
Between can arrange as the case may be and flexibly, such as, refrigerator every 5 seconds gather refrigerator compartment temperature.
During refrigerator constantly gathers compartment temperature with interval Preset Time, due to the memory space of refrigerator

Accordingly, as shown in Figure 4, one control device of refrigerator first embodiment of the present invention is proposed.This is real
The control device of refrigerator executing example includes:
First acquisition module 100, for obtaining the compartment temperature of refrigerator every Preset Time；
In the present embodiment, between refrigerator, indoor are provided with temperature sensor, the temperature of room between gathering.
Between refrigerator, room includes freezing compartment, refrigerator room etc., and the number of freezing compartment and refrigerator room can basis
It is actually needed and is configured.Each room of refrigerator can arrange one or more temperature sensor, alternatively,
When between one, indoor exist multiple temperature sensor, the temperature that multiple temperature sensors collect can be taken
The temperature of this room it is set as after average.
After refrigerator is opened, the first acquisition module 100 indoor preset temperature between Preset Time passes through passes
The compartment temperature of sensor detection refrigerator, alternatively, between continuous multiple time points can be acquired by refrigerator
Room temperature stores, in order to entered by the compartment temperature of the compartment temperature of current point in time with a upper time point
Row compares.This Preset Time can be arranged as the case may be and flexibly, and such as, refrigerator gathered every 5 seconds
The compartment temperature of refrigerator.During refrigerator constantly gathers compartment temperature with interval Preset Time, by
In the limited storage space of refrigerator, refrigerator can be set and only store the compartment temperature presetting a time point, will be
The compartment temperature newly collected replaces the compartment temperature collected the earliest in the data stored, between updating
The storage data of room temperature.
Judge module 200, for judging whether current compartment temperature is more than the compartment temperature of a upper time point,
And whether the temperature difference between described current compartment temperature and described compartment temperature exceedes preset temperature threshold value；
Control module 300 if being more than the compartment temperature of a upper time point and described for current compartment temperature
The current temperature difference between compartment temperature and described compartment temperature exceedes preset temperature threshold value, then control described ice
Case enters quick-freezing/quickly cooling pattern；
After obtaining compartment temperature, it is judged that module 200 is by the current compartment temperature of current point in time and upper
The compartment temperature of time point compares, if current compartment temperature is more than the compartment temperature of a upper time point,
And currently compartment temperature T1 is more than the temperature Δ T=T1-T2 between the compartment temperature T2 of a upper time point, super
Cross preset temperature threshold value, then between judging there is overheating in room, it may be possible to user has put into temperature toward refrigerator
Higher food, now, control module 300 controls refrigerator and enters quick-freezing/quickly cooling pattern, to control rapidly
Compartment temperature returns back to the target temperature set, it is ensured that the effect that food preserves.This target temperature is refrigerator
Normally freeze the temperature being to set, it is also possible to be that user passes through preset to run by key assignments refrigerator
Temperature, this preset temperature threshold value can be configured as the case may be.
If current compartment temperature is less than or equal to the compartment temperature of a upper time point, or, current room temperature
Degree is less than or equal to the compartment temperature of a upper time point, and current temperature between compartment temperature and compartment temperature
Difference is not above preset temperature threshold value, then explanation need not quick-freezing/quickly cooling, and refrigerator maintains current refrigeration mould
Formula is run.
During owing to gathering compartment temperature first, refrigerator has only stored a compartment temperature, does not goes up one
The compartment temperature of time point compares, and therefore, refrigerator can first judge whether to deposit after gathering compartment temperature
Contain the compartment temperature of a time point, if storage has, then current compartment temperature is stored, and
Can compare with the compartment temperature of a upper time point, without storage, then store current compartment temperature,
Update storage data.
It is understood that when refrigerator includes multiple freezing compartment and multiple refrigerator room, can distinguish every
Each freezing compartment and the compartment temperature of refrigerator room is detected every Preset Time, and respectively to each room
Current compartment temperature judges with the compartment temperature of a upper time point.The preset temperature that freezing compartment is arranged
Threshold value, the preset temperature threshold value arranged with refrigerator room can be inconsistent.
Adjustment module 400, does not perform defrost behaviour for controlling described refrigerator under described quick-freezing/quickly cooling pattern
Make, and regulate the compressor operating rotating speed of described refrigerator and fan operation rotating speed respectively to specifying rotating speed.
After refrigerator enters quick-freezing pattern, if refrigerator needs to enter defrost under quick-freezing pattern just, when
Compartment temperature can be made when carrying out defrost abnormal, affect food preservation effect.Therefore under this quick-freezing pattern,
Adjustment module 400 controls refrigerator and is not carried out defrosting operation, if desired carries out defrost, then can postpone when secondary
Defrost.By postponing when time defrost, High cooling power can be added, to control compartment temperature as early as possible to normal level,
Ensure the effect of food preservation.
Meanwhile, under this quick-freezing pattern, adjustment module 400 improves the running speed of compressor and blower fan,
To improve cold, the compressor operating rotating speed of refrigerator and fan operation rotating speed can be regulated respectively to specifying rotating speed,
This appointment rotating speed can be arranged as the case may be and flexibly.Specifically, by compressor operating rotational speed regulation extremely
First tachometer value, by fan operation rotational speed regulation to the second tachometer value, such as, by compressor operating rotating speed
Regulate to the tachometer value corresponding to high tap position, or by compressor operating rotational speed regulation to time high tap position institute
