In the case of being not turned on, continuation is run with normal refrigerating mode.
Step 206, detect whether the compartment temperature is more than current turn-on temperature, when the compartment temperature is more than currently
The turn-on temperature when, compressor operating is controlled according to third turn-on temperature and third shutdown temperature, wherein the third is opened
Machine temperature is more than the current turn-on temperature, and the third shutdown temperature is less than the current corresponding shutdown of the turn-on temperature
Temperature.
It is noted that current turn-on temperature can be the first turn-on temperature, can also be the second turn-on temperature, when
Preceding shutdown temperature can be the first shutdown temperature, can also be the second shutdown temperature, be opened for first in current turn-on temperature
When machine temperature, then current shutdown temperature is the first shutdown temperature, when current turn-on temperature is the second turn-on temperature, then currently
Shutdown temperature is the second shutdown temperature.Current turn-on temperature and current shutdown temperature determine according to current environment temperature,
And control compressor operating after into refrigeration amplification pattern, that is, according to third turn-on temperature and third shutdown temperature
When, current turn-on temperature is then third turn-on temperature, and current shutdown temperature is then third shutdown temperature.
Specifically, when compartment temperature is more than current turn-on temperature, show that compartment is by extraneous air or object at this time
The influence of body, compartment temperature rise, and control compressor operating according to third turn-on temperature and third shutdown temperature at this time, due to the
Three turn-on temperatures are more than current turn-on temperature, and third shutdown temperature is less than current shutdown temperature, in this way, third booting temperature

Degree is more average, and makes the indoor refrigeration that can be obtained rapidly and efficiently, achievees the purpose that fast-refrigerating.
It is noted that in the present embodiment, turn-on temperature is opened including the first turn-on temperature, the second turn-on temperature and third
Machine temperature, shutdown temperature include the first shutdown temperature, the second shutdown temperature and third shutdown temperature, the first turn-on temperature, second
Turn-on temperature, third turn-on temperature, the first shutdown temperature, the second shutdown temperature and third shutdown temperature can precalculate to obtain
, and it is pre-set, can also be to calculate acquisition in real time according to temperature detection result, specific calculating process refers to following reality
Apply example.
In the present embodiment, after detecting that refrigerator doors are opened, compartment is connected to outside, causes indoor temperature rise,
Therefore, after detecting that compartment temperature rises, into refrigeration amplification pattern, pass through the third turn-on temperature of the difference of bigger and the
Three shutdown temperatures extend the single working time of compressor, achieve the purpose that fast-refrigerating.
In one embodiment, refrigerator temperature control method further includes：Continuously carry out it is described according to third turn-on temperature and
The step of third shutdown temperature controls the step of compressor operating, and after preset time, the return acquisition environment temperature.This
In embodiment, after the preset time for executing step 206, return to step 102.That is, with third turn-on temperature and
Three shutdown temperatures control compressor cycle work a period of time.
For example, cycle executes described the step of controlling compressor operating according to third turn-on temperature and third shutdown temperature,
And after preset time, return the acquisition environment temperature the step of.Specifically, third turn-on temperature is risen in compartment temperature
Afterwards, compressor operating is controlled so that compartment temperature reduces, and after compartment temperature is reduced to third shutdown temperature, controls compressor
It is stopped, after a period of time after compressor is stopped, compartment temperature rises to third turn-on temperature, again control pressure
Contracting machine works, and described the step of controlling compressor operating according to third turn-on temperature and third shutdown temperature is executed to recycle.
After cycle execution above-mentioned steps reach preset time, it is back to step 202.
Specifically, after refrigerator doors are opened, refrigerator enters refrigeration amplification pattern, runs, passes through under amplification pattern of freezing
The third turn-on temperature and third shutdown temperature of larger difference control compressor operating so that compressor separate run times are more
It is long, achieve the purpose that fast-refrigerating, reach in the temperature of compartment or stablize after preset temperature, exits refrigeration amplification pattern,
Return to step 102, that is, enter normal operation mode, it is ensured that the temperature control precision of refrigerator improves.
In one embodiment, refrigerator temperature control method further includes：When the compartment temperature is less than or equal to currently
When the turn-on temperature, return the acquisition environment temperature the step of.For example, step 206 is also wrapped
It includes when the compartment temperature is less than or equal to the current turn-on temperature, return to step 102.
In the present embodiment, after refrigerator doors opening, compartment temperature is influenced smaller by the temperature of external environment so that
Room temperature is not rising to significantly more than turn-on temperature, then return to step 102, that is, maintains under normal refrigerating mode
Operation, to realize accurately controlling to the temperature of refrigerator compartment.
In one embodiment, whether the detection compartment temperature is more than current the sum of turn-on temperature, when described
When compartment temperature is more than the current turn-on temperature, compressor operating is controlled according to third turn-on temperature and third shutdown temperature
The step of include：Detect whether the compartment temperature is more than the sum of current turn-on temperature and default bias amount, when the compartment
When temperature is more than the sum of the current turn-on temperature and described default bias amount, temperature is shut down according to third turn-on temperature and third
Degree control compressor operating.
Specifically, which is temperature value, which is set as according to the difference of model of refrigerator
Different numerical value, specifically, the volume of different model of refrigerator, compartment are different, in this way, after the refrigerator doors of compartment are opened,
Internal range of temperature also differs, and therefore, using different default bias amounts, can be adapted to the appearance of different compartments
Product, and then realize and accurately control.
The default bias amount is constant, for example, the default bias amount is 0,1,2,3,4 ... in this way, by detecting compartment
Whether temperature is more than the sum of turn-on temperature and default bias amount, improves the detection reference data of compartment temperature so that in compartment
In the case of temperature is higher, refrigerator just enters refrigeration amplification pattern, and can carry out room temperature according to the size of refrigerator compartment
The judgement of degree carries out judging whether to enter refrigeration enhancement mode according to this, can improve judgement precision so that enters refrigeration amplification mould
Formula is more accurate.
In one embodiment, first turn-on temperature is inclined according to high temperature section startup-shutdown point on the basis of preset temperature
Shifting amount, which calculates, to be obtained, and first shutdown temperature is obtained on the basis of preset temperature according to the calculating of high temperature section startup-shutdown point offset
, for example, on the basis of preset temperature, positive offset is carried out with high temperature section startup-shutdown point offset and calculates acquisition first booting
Temperature carries out negative offset with high temperature section startup-shutdown point offset and calculates acquisition first shutdown temperature.
Second turn-on temperature is calculated according to low-temperature zone startup-shutdown point offset and is obtained on the basis of preset temperature, institute
The second shutdown temperature is stated on the basis of preset temperature, is calculated and is obtained according to low-temperature zone startup-shutdown point offset, for example, with default temperature
On the basis of degree, positive offset is carried out with low-temperature zone startup-shutdown point offset and calculates acquisition second turn-on temperature, is opened with low-temperature zone
Break point offset carries out negative offset and calculates acquisition second shutdown temperature.
Wherein, high temperature section startup-shutdown point offset is more than low-temperature zone startup-shutdown point offset.
It is opened for example, being calculated with the sum of half of preset temperature and high temperature section startup-shutdown point offset and obtaining described first
Machine temperature is calculated with the difference of preset temperature and the half of high temperature section startup-shutdown point offset and obtains the first shutdown temperature
Degree.It is calculated with the sum of half of preset temperature and low-temperature zone startup-shutdown point offset and obtains second turn-on temperature, with
The difference of the half of preset temperature and low-temperature zone startup-shutdown point offset, which calculates, obtains second shutdown temperature.
Specifically, preset temperature is also referred to as set temperature, or referred to as target temperature.The preset temperature can receive user
Control instruction setting, can also be default setting.The preset temperature is the temperature of compartment set by user.
The first turn-on temperature, the first shutdown temperature, the second turn-on temperature and second for calculating acquisition by the above process stop
Machine temperature, the first turn-on temperature are more than preset temperature, and the first shutdown temperature is less than preset temperature, in this way, rising in compartment temperature
When to the first turn-on temperature, compressor operating, when compartment temperature drops to the first shutdown temperature, compressor is stopped, this
Sample so that compartment temperature is able to maintain that in preset temperature, in other words, compartment temperature maintains wave in a certain range of preset temperature
Dynamic, similarly, the second turn-on temperature is more than preset temperature, and the second shutdown temperature is less than preset temperature so that compartment temperature maintains
Fluctuation in a certain range of preset temperature.And since high temperature section startup-shutdown point offset is more than low-temperature zone startup-shutdown point offset,
So that the difference between the first turn-on temperature and the first shutdown temperature is more than between the second turn-on temperature and the second shutdown temperature
Difference so that each position in refrigerator compartment can be freezed well so that the temperature of each position is more average,
It maintains the Homes Using TV of compressor to stablize, energy consumption is effectively reduced, and improve temperature control precision, so that indoor only need one
The control of temperature can be realized in a temperature sensor, effectively reduces production cost.
Here is a specific embodiment：
In the present embodiment, the refrigerator includes refrigerator control module, environment temperature sensor, compartment temperature sensor.
The environment temperature sensor (calling circumstance temperature sensor in the following text) feeds back to control module for detecting environment temperature.
The compartment temperature sensor (calling compartment sensor in the following text) feeds back to control mould for acquiring monitoring compartment temperature
Block.
The control module prestores normal refrigerating mode and refrigeration amplification mode control logic.
For example, control module is for obtaining environment temperature；Detect whether the environment temperature is less than default environment temperature；When
When the environment temperature is greater than or equal to the default environment temperature, according to the first turn-on temperature and the first shutdown temperature control pressure
Contracting machine works；When the environment temperature is less than the default environment temperature, according to the second turn-on temperature and the second shutdown temperature
Control compressor operating.
For example, control module is additionally operable to whether detection refrigerator doors are opened；After detecting that refrigerator doors are opened, between acquisition
Indoor compartment temperature；Detect whether the compartment temperature is more than current turn-on temperature, when the compartment temperature is more than currently
The turn-on temperature when, compressor operating is controlled according to third turn-on temperature and third shutdown temperature.
As shown in Figure 3A, under normal refrigerating mode, environment temperature is arranged to several continuous sections, in this implementation
Environment temperature is divided into TRing< Tm、TRing≥TmTwo sections, wherein TRingFor environment temperature, TmTo preset environment temperature.Circumstance temperature senses
Device continuously monitors refrigerator local environment temperature, when circumstance temperature sensor detects TRing≥TmWhen, then refrigerator starting point is set as TOpen 1=t+
B/2, means for refrigerator when stopping working point are set as TStop 1=t-b/2, wherein TOpen 1For the first turn-on temperature, TStop 1For the first shutdown temperature, t is pre-
If temperature, b is refrigerator startup-shutdown point deviation constant, also referred to as high temperature section startup-shutdown point offset, value range such as 1,2,3,
4 ..., when circumstance temperature sensor detects TRing< TmWhen, then refrigerator starting point is set as TOpen 2=t+a/2, means for refrigerator when stopping working point are set as
TStop 2=t-a/2, wherein TOpen 2For the second turn-on temperature, TStop 2For the second shutdown temperature, t is preset temperature, and a is refrigerator start-stop
Machine point deviation constant, also referred to as low-temperature zone startup-shutdown point offset, value range 1,2,3,4 ..., and high temperature section startup-shutdown
Point offset b > low-temperature zones startup-shutdown point offsets a.
As shown in Figure 3B, under amplification pattern of freezing, after monitoring refrigerator open action, compartment sensor temperature is monitored
T is passed.If TIt passes> TIt opens+ n, wherein TOpen 3For current turn-on temperature, n is constant 1,2,3 ..., and n takes according to product type difference, n
Value is different, then refrigerator starting point is set as TOpen 3=t+ (a+c)/2, means for refrigerator when stopping working point are set as TStop 3=t- (a+c)/2, wherein
TOpen 3For third turn-on temperature, TStop 3For third shutdown temperature, t is preset temperature, and a is refrigerator original startup-shutdown point deviation constant, and c is
Amplification startup-shutdown point deviation constant, value such as 1,2,3,4 ... continue to increase startup-shutdown point on the basis of original startup-shutdown point
Offset.After refrigerator is with amplification mode operation N number of period or continuous service T hours, refrigerator exits refrigeration amplification pattern, with just
Normal refrigeration mode operation.
It is noted that under above-mentioned refrigeration amplification pattern, corresponding is TRing< TmWhen operating status, therefore have, TOpen 3
=t+ (a+c)/2, TStop 3=t- (a+c)/2, works as TRing≥TmWhen, then the starting point of refrigerator is T under amplification pattern of freezingOpen 3=t+
(b+c)/2, break point TStop 3=t- (b+c)/2.That is, under amplification pattern of freezing, third turn-on temperature is current
Continue to increase on turn-on temperature, and shutdown temperature is further decreased on the basis of current shutdown temperature, so that system
Cold amplification pattern can be matched with environment temperature so that temperature control is more accurate, and further increases refrigerating efficiency.
In the present embodiment, when ambient temperatures are low, refrigerator thermic load is smaller, and upper and lower temperature difference is small, therefore uses smaller temperature
Spend offset so that compartment temperature fluctuation is small, and temperature control is accurate；When environment temperature is high, refrigerator thermic load is big, compartment upper and lower temperature difference
Greatly, therefore larger temperature offset amount is used so that compartment cooling time is long, to reduce refrigerator upper and lower temperature difference, reaches accurate
The purpose of temperature control, meanwhile, because its Homes Using TV is constant, but on-off frequency is few, reduces energy consumption；When detecting refrigerator compartment temperature because opening
Door or when being put into food and causing excessively high, then enter refrigeration amplification pattern, increase startup-shutdown point offset, extend cooling time,
So that high-temperature area temperature is rapidly decreased to target temperature, and in operation some cycles backed off after random refrigeration amplification pattern, between diminution
Room temperature fluctuates.
In addition, in the present embodiment, each single compartment of refrigerator only needs a sensor detection compartment temperature, reduces ice
Case cost and power consumption；It can ensure that the intersegmental indoor temperature of each circumstance temperature is stablized again simultaneously by adjusting startup-shutdown point offset,
It is excessively high to avoid the occurrence of local temperature；And be put into article or switch gate cause temperature excessively high after can enter refrigeration amplification pattern,
It is quickly cooled down so that being put into article, while refrigerator compartment temperature being kept to stablize.
In above-described embodiment, single compartment temperature is controlled using single sensor, refrigerator is at low cost, and low energy consumption；And it is normal
Low circumstance temperature compartment temperature upper and lower temperature difference is small under operational mode, and startup-shutdown point offset is small, and temperature control precision is high；High circumstance temperature start-stop
Machine point offset is big, although temperature fluctuation is big, compartment upper and lower temperature difference is small, ensures that each position of compartment can reach target temperature,
