Temperature sensor 5 is located at fresh-keeping box body 1 rear portion one lateral edges, and air channel is located at fresh-keeping box body 1 rear portion interposition
Put.
The rear portion in ice greenhouse 6 also has blowing mouth, blowing mouth towards in ice greenhouse, its air-out direction and fresh-keeping box body 1
The air-out direction of the blowing mouth 3 of setting is parallel.The volume in ice greenhouse 6 is more than the volume of fresh-keeping box body 1.
The crisper of the present embodiment can make food keep fresh at least one week, and structure is simple, easy to use, refrigerator
It is provided with that fresh-keeping effect after this crisper is more preferable, Consumer's Experience is good.
A kind of food fresh keeping control method based on above-mentioned refrigerator, at least includes：Food in fresh-keeping box body 1 is made to enter
The step of the state of cooling, the maintenance step of supercooling state and the step of intensification.
In order to more fully understand the present embodiment, the concrete steps of food fresh keeping control method are described as follows：
In Fig. 3, from the beginning of timing, the three phases of arrows are respectively the supercooling stage that enters, maintain supercooling rank
Section and temperature rise period, this three phases is built into a cycle period；Curve 1 is temperature sensor copper post temperature curve, curve 2
It is placed in the food temperature change curve being not required in refrigerator when thawing for food, curve 3 need to release supercooling and defrosting shape for food
Food temperature change curve during state；
Step S1, control unit control temperature sensor 5, detect temperature in fresh-keeping box body 1 by temperature sensor 5,
Detection signal is passed to judging unit, control unit controls the operating frequency of fan, compressor and air door 4, makes fresh-keeping simultaneously
In box body 1, food temperature reaches the preset value of supercooling state；
Step S2, all can affect overcooled sustainment rate due to various unstable factors, for example, the species of food, size,
Packaged configuration etc., thus need to first carry out maintaining the presetting, then further according to fresh-keeping box body 1 interior temperature of supercooling state for time
Angle value, control unit controls the operating frequency of compressor and the opening and closing frequency of air door 4 to make food in fresh-keeping box body 1 remain supercool
But state Preset Time, thus reduce the temperature fluctuation in fresh-keeping box body 1；
Step S3, control unit balance according to heat budget and obtain food intensification required time, are carried out using heater 2
Heat up, wherein, Fig. 4 is the time dependent curve of temperature of food, from starting timing, the three phases of in figure arrows
Be respectively and enter supercooling, from releasing time period of counting of supercooling and thaw the time period needing, in figure, heat budget balances
Formula is：Q1+Q2=Q3；
Step S4, intensification go to step S1 after terminating.
Additionally, food fresh keeping control method also includes the step thawed, when food needs to thaw, display unit is solved
Freeze function to set, it is food intensification that control unit directly goes to step S3, i.e. the step of only execution step S3, wherein, intensification institute
Take time equal to defrosting required time, after defrosting terminates, display unit carries out defrosting function and terminates to point out.
Above-mentioned control method makes food enter supercooling state and make by arranging a single crisper in refrigerator
Supercooling state keeps certain time, makes supercooling status releasing afterwards, and the ice crystal generating is dissolved.This control method
The food can be made to keep fresh at least one week, it is to avoid during food product refrigeration, lead to protein denaturation, cell tissue to be damaged etc.
Problem, makes food nutrition not easily run off, and the food after intensification can reach the hardness that can cut, and defrosting effect is more preferable, this controlling party
Method solves multiple problems that existing control method exists, and storage time is longer, and fresh-keeping effect is more preferable.
Finally in addition it is also necessary to explanation, herein, term " inclusion ", "comprising" or its any other variant are intended to
Cover comprising of nonexcludability, so that including a series of process of key elements, method, article or equipment not only include those
Key element, but also include other key elements being not expressly set out, or also include for this process, method, article or set
Standby intrinsic key element.In the absence of more restrictions, the key element that limited by sentence "including a ..." it is not excluded that
