Refrigerating chamber 11 and refrigerating chamber 12 are isolated by a heat insulation layer 13, and heat insulation layer 13 is by the first wall 16, the refrigerating chamber positioned at refrigerating chamber 12
11 the second wall 14 and the foaming layer 15 between the first wall 16 and the second wall 14 are formed, in actual product, in order to subtract
Influence of the thickness of few foaming layer 15 to dischargeable capacity in refrigerator, the generally thickness by foaming layer 15 are arranged to 30mm or so, this
A thickness can not prevent the heat exchange between the first wall 16 and the second wall 14 completely.In addition, refrigerating chamber 12 also can be by except first
Heat exchange occurs for the air around other walls and refrigerator outside wall 16, this is also refrigerating chamber 12 per temperature will after a while
Rise, so that the main reason for needing refrigeration.
Reaching the temperature in the refrigerating chamber 11 of three-star freezing needs subzero 18 degrees Celsius, the temperature that refrigerating chamber 12 is set
Generally more than zero degree, refrigerating chamber and the indoor temperature difference of refrigeration are easier to more than 20 degrees Celsius, therefore in the first wall 16 and second
Existing heat exchange can cause the temperature on the first wall 16 significantly lower than the temperature in refrigerating chamber 12 between wall 14, so as to reduce cold
Hide the temperature of room 12；In the case where refrigerator environment temperature is less than refrigerating chamber normal operating temperature（It is such as warm around winter refrigerator
Degree is less than zero degree, and the temperature of refrigerating chamber is more than zero degree）, enter refrigerating chamber, refrigerating chamber around refrigerator almost without heat
Low temperature is kept, does not reach the condition of triggering refrigeration chamber.If the compressor that low-temperature receiver is provided to refrigerating chamber does not work for a long time,
Refrigeration indoor humidity increases considerably, and is on the one hand unfavorable for food fresh-keeping beyond the humidity of zone of reasonableness, on the other hand substantial amounts of
Aqueous vapor easily forms condensation on the first wall 16.Therefore, it is necessary to the program of dehumidifying is set in refrigerator.
Dehumidifying program is arranged in the control unit of refrigerator, and specific steps please refer to Fig.2, the dehumanization method in Fig. 2, including
Following steps：
Step 30：The temperature of the extraneous air around refrigerating appliance is detected, passes through the temperature detector being arranged on refrigerator
Detect external air temperature；
Step 31：Judge whether the temperature of the detection is more than the first preset temperature, if more than the first preset temperature, then return
Step 30, if being less than or equal to the first preset temperature, it is transferred to step 32, the value of the first preset temperature depends on refrigerating chamber and cold
Freeze the design temperature of room and the thickness of refrigerating appliance heat insulation layer, the meaning of the first preset temperature is when extraneous temperature is equal to
During the first preset temperature, the energy of the heat exchange between extraneous and refrigerating chamber is equal to the heat exchange between refrigerating chamber and refrigerating chamber,
Refrigerating chamber reaches thermal balance without refrigeration, therefore is opened using the first preset temperature as whether the temperature for weighing extraneous air reaches
The requirement of dynamic refrigerating appliance dehumidifying program；
Step 32：Whether refrigerating chamber time for continuing not freeze is judged more than the first preset time, if it is not, then return to step
30, if so, then entering dehumidifying program, step 33 is transferred to, from above procedure, to enter refrigerator dehumidifying program needs exterior sky
The time that the temperature and refrigerating chamber of gas continue not freeze meets the condition of setting at the same time, and the value of the first preset time depends primarily upon
The volume of refrigerating chamber and the thickness of heat insulation layer, when not freezing more than the first preset time, refrigeration indoor humidity reaches can not
For the degree of tolerance, it is necessary to dehumidify, humidity is excessive in addition to being possible to influence food fresh-keeping in refrigerator, can also be on the wall in babinet
Substantial amounts of condensation is formed, is unfavorable for the raising of refrigeration for refrigerator efficiency；
Step 33：Heater and fan heating refrigerating chamber are operated, concrete mode can be by being arranged near heater
The hot-air of heated generation around heater is introduced refrigerating chamber by fan, so as to improve the temperature of refrigerating chamber to can as little as touch
Hair starts compressor to refrigerating chamber cooling, but heating time also can not be too long, and the time is too long to cause refrigeration for refrigerator efficiency
Serious reduction, so giving heater on time to set one second preset time, it is pre- to reach second in heater on time
If after the time, continuing following step, the second preset time depends on the heater efficiency of heating surface and the size of volume of refrigerating chamber, separately
Outside, confirm that the compressor is closed before operation heater heating refrigerating chamber, avoid at the same time carrying out refrigerating chamber
Heating and refrigeration；
Step 34：Operation operation compressor cooling and refrigeration room, again by the effect of fan enhancing cooling.
Above procedure is arranged in the control unit of refrigerator, passes through temperature detector, compression in the programme-control refrigerator
Machine, fan, heater operation come be reached for refrigerating chamber dehumidifying purpose.
The above method is equally applicable in two-door refrigerator, three-door refrigerator and multi-door refrigerator.
The dehumanization method of another embodiment comprises the following steps：Refrigerator is determined according to the time that refrigerating chamber continues not freeze
Whether tool enters dehumidification mode；If into dehumidification mode, by operating heater and fan heating refrigerating chamber and passing through behaviour
Make compressor cooling and refrigeration room.
Compared to the decision condition into dehumidification mode of first embodiment, the embodiment is only by judging that refrigerating chamber holds
The continuous time do not freezed determines whether to enter dehumidification mode, although this is because causing the factor that refrigerating chamber does not freeze for a long time
It is but the it could also be possible that other factors because refrigerating appliance environment temperature is relatively low in the case of being mostly.For example, in refrigerating appliance week
Enclose it is normothermic in the case of, block of ice either user is placed into refrigerating chamber needs the frozen article that thaws, then equally
It is possible to that temperature of refrigerating chamber can be caused to keep low temperature for a long time, and does not reach the condition of triggering refrigeration chamber.For this feelings
Dehumidifying under condition, the time that can not freezed by only judging refrigerating chamber to continue decide whether to enter dehumidification mode.
