1in, the triple valve 140 in the refrigeration system of refrigerator is switched to the second refrigerating circuit, and now refrigerator freezes to refrigerating chamber, and the refrigeration of refrigerating chamber and medial compartment stops, and fan 220 is with the current on time R of regulation
1(t as shown in Figure 6
10in time) action.Like this, by the action of fan 220, the temperature of refrigerating chamber and medial compartment rises, thus can prevent the fan 220 in medial compartment from freezing.
In time period t
2in, i.e. when the temperature of refrigerating chamber, medial compartment and refrigerating chamber meets cryogenic conditions (temperature that such as temperature of refrigerating chamber is 0 ~ 10 DEG C, medial compartment temperature is 0 ~ 6 DEG C and refrigerating chamber is below-18 DEG C), the compressor of refrigerator quits work.Now, according to the environment temperature of refrigerator, heated to medial compartment evaporimeter 180 a period of time, and the fan 220 in medial compartment is with current on time R
2(t as shown in Figure 6
20in time) work.When the temperature of medial compartment is lower (such as below 0 DEG C), heater 181 pairs of medial compartment evaporimeters 180 of refrigerator heat, and the fan 220 simultaneously in medial compartment runs; When the temperature return of medial compartment is to more than 0 DEG C, the heater 181 on medial compartment evaporimeter 180 quits work, and fan 220 is with current on time R
2action, thus ensure that the fan 220 in medial compartment can not freeze.
Refer to the concrete storehouse temperature of refrigerating chamber, medial compartment and refrigerating chamber room between each although above-mentioned, suitable adjustment said temperature is also allow.Such as refrigerating chamber can at 0 ~ 6 DEG C, 0 ~ 8 DEG C or 0 ~ 4 DEG C; Medial compartment can at 0 ~ 2 DEG C, 0 ~ 4 DEG C and 0 ~ 6 DEG C; Refrigerating chamber can below-16 DEG C.
" current on time " mentioned in present embodiment refers to that (such as refrigerating chamber is in the time of refrigeration in the some cycles time, or refrigerating chamber and medial compartment are when refrigeration) the ratio of conduction time, the control situation different according to refrigerator, current on time (such as current on time R above-mentioned
1, R
2) can be 1%, 2%, 5%, 10%, 20%, 50% etc.Above-mentioned in the control procedure of medial compartment indoor fan 220 and medial compartment evaporimeter 180 upper heater 181, the temperature-adjusting device of different temperatures can be set, by making the different current on times of the heater 181 on the corresponding medial compartment indoor fan 220 of different temperature and medial compartment evaporimeter 180, thus the difference " current on time " of medial compartment indoor fan 220 and medial compartment evaporimeter 180 can be realized by design temperature adjusting device, thus the temperature making medial compartment reach suitable (such as 0 ~ 6 DEG C).This temperature control set for adjusting can use the temperature-adjusting device of prior art.
Specifically, in the present embodiment, user can carry out the adjustment of different " current on time " according to concrete working environment and job requirement to the medial compartment indoor fan 220 of refrigerator and medial compartment evaporimeter 180.Such as, at summer environment temperature, environment temperature higher (being such as more than 25 DEG C), temperature difference inside and outside refrigerator is larger, between refrigerator, the indoor temperature energy that 1 DEG C of needs expends that often declines increases, and scattered and disappeared by heat-insulation layer and door seal cold air and also can accelerate, therefore, need the refrigeration intensity heightening refrigerating chamber, now the current on time of fan 220 correspondence of medial compartment indoor can uprise, and the current on time of the heater on medial compartment evaporimeter 180 is then lower.Similarly, under autumn and winter season environment temperature, correspondingly change the current on time of the fan 220 of medial compartment indoor and the heater 181 of medial compartment evaporimeter 180.
