[detailed description of the invention]
For making object of the present invention, scheme and beneficial effect clearly understand, below in conjunction with accompanying drawing and preferred embodiment, the invention will be further described.
Present embodiment is for side by side combination refrigerator.
Fig. 1 is the schematic diagram of side by side combination refrigerator, side by side combination refrigerator 10 comprises refrigerating chamber 11 and the refrigerating chamber 12 of left and right distribution, refrigerating chamber 11 and refrigerating chamber 12 are isolated by a heat insulation layer 13, heat insulation layer 13 is by the first wall 16 being positioned at refrigerating chamber 12, second wall 14 of refrigerating chamber 11 and the foaming layer 15 between the first wall 16 and the second wall 14 are formed, in actual product, in order to reduce the thickness of foaming layer 15 to the impact of dischargeable capacity in refrigerator, generally the thickness of foaming layer 15 is arranged to about 30mm, this thickness cannot stop the heat exchange between the first wall 16 and the second wall 14 completely.In addition, refrigerating chamber 12 also can by other walls except the first wall 16 and refrigerator ambient air generation heat exchange, and this is also that the every temperature after a while of refrigerating chamber 12 will raise, thus needs the main cause of refrigeration.
The temperature reached in three-star freezing refrigerating chamber 11 needs subzero 18 degrees Celsius, the temperature that refrigerating chamber 12 sets is generally above zero, temperature difference in refrigerating chamber and refrigerating chamber is more easily more than 20 degrees Celsius, therefore the heat exchange existed between the first wall 16 and the second wall 14 can make the temperature on the first wall 16 be starkly lower than temperature in refrigerating chamber 12, thus reduces the temperature of refrigerating chamber 12; In refrigerator environment temperature, lower than when refrigerating chamber normal operating temperature, (such as winter, refrigerator environment temperature was lower than zero degree, and the temperature of refrigerating chamber is above zero), almost do not have heat to enter refrigerating chamber around refrigerator, refrigerating chamber keeps low temperature, does not reach the condition triggering refrigeration chamber.If provide the compressor of low-temperature receiver not work for a long time to refrigerating chamber, refrigerating chamber humidity increases considerably, and the humidity exceeding zone of reasonableness is unfavorable for food fresh-keeping on the one hand, and a large amount of aqueous vapors easily forms condensation on the first wall 16 on the other hand.Therefore, the program that dehumidifying is set in refrigerator is necessary.
Dehumidifying program is arranged in the control unit of refrigerator, and concrete steps please refer to Fig. 2, and the dehumanization method in Fig. 2, comprises the following steps:
Step 30: the temperature detecting the extraneous air around refrigerating appliance, detects external air temperature by the temperature detector be arranged on refrigerator;
Step 31: judge whether the temperature of this detection is greater than the first preset temperature, if be greater than the first preset temperature, then return step 30, if be less than or equal to the first preset temperature, then proceed to step 32, the value of the first preset temperature depends on the design temperature of refrigerating chamber and refrigerating chamber and the thickness of refrigerating appliance heat insulation layer, the meaning of the first preset temperature is when extraneous temperature equals the first preset temperature, the energy of the heat exchange between the external world and refrigerating chamber equals the heat exchange between refrigerating chamber and refrigerating chamber, refrigerating chamber reaches thermal balance without the need to refrigeration, therefore whether reach the requirement starting refrigerating appliance dehumidifying program as the temperature weighing extraneous air using the first preset temperature,
Step 32: whether the time that judgement refrigerating chamber continues not freeze is more than the first Preset Time, if not, then return step 30, if, then enter dehumidifying program, proceed to step 33, from said procedure, the time that entering refrigerator dehumidifying program needs the temperature of extraneous air and refrigerating chamber to continue not freeze meets the condition set simultaneously, the value of the first Preset Time depends primarily on the volume of refrigerating chamber and the thickness of heat insulation layer, when not freezing more than the first Preset Time, refrigerating chamber humidity reaches the degree that can not put up with, need dehumidifying, refrigerator humidity is excessive except likely affecting except food fresh-keeping, also the wall in casing can form a large amount of condensations, be unfavorable for the raising of refrigeration for refrigerator efficiency,
Step 33: operate heater and fan heating refrigerating chamber, concrete mode can will introduce refrigerating chamber through adding thermogenetic hot-air around heater by being arranged on fan near heater, thus the temperature improving refrigerating chamber at least starts to the compressor of refrigerating chamber cooling to triggering, but the heat time also can not be oversize, time oversize meeting causes the serious reduction of refrigeration for refrigerator efficiency, so to heater on time setting one second Preset Time, after heater on time reaches the second Preset Time, continue step below, second Preset Time depends on the size of the heater efficiency of heating surface and volume of refrigerating chamber, in addition, before operate heater heating refrigerating chamber, confirm that described compressor is in closed condition, avoid heating refrigerating chamber simultaneously and freezing,
Step 34: operation operate compressor refrigerated compartment, strengthens the effect of cooling equally by fan.
Said procedure is arranged in the control unit of refrigerator, is reached for the object of refrigerating chamber dehumidifying by the operation of temperature detector, compressor, fan, heater in this programme-control refrigerator.
Said method is applicable equally in two-door refrigerator, three-door refrigerator and multi-door refrigerator.
The dehumanization method of another embodiment comprises the following steps: determine whether refrigerating appliance enters dehumidification mode according to the time that refrigerating chamber continues not freeze; If enter dehumidification mode, then heat refrigerating chamber by operate heater and fan and pass through operate compressor refrigerated compartment.
Compared to the decision condition entering dehumidification mode of the first embodiment, this embodiment is only by judging that the time that refrigerating chamber continues not freeze determines whether to enter dehumidification mode, although this is the factor owing to causing refrigerating chamber not freeze for a long time is be because refrigerating appliance environment temperature is lower in situation mostly, is also likely other factors.Such as, in the normal situation of refrigerating appliance environment temperature, be placed into the frozen article that block of ice or user need to thaw in refrigerating chamber, then temperature of refrigerating chamber equally likely can be caused to keep low temperature for a long time, and do not reach the condition triggering refrigeration chamber.For dehumidifying in this case, can by only judging that the time that refrigerating chamber continues not freeze determines whether entering dehumidification mode.
