Prior art controls defrost shift duration and controls a room temperature-sensing probe startup-shutdown temperature mainly through pre-set refrigerator compartment temperature; thus periodic refrigerating is carried out to refrigerator compartment, slowly refrigerator compartment temperature is withdrawn into the state of stable operation before defrost by periodic refrigerating.
As shown in Figure 1, refrigerator compartment design temperature is T1, and between corresponding, room temperature-sensing probe turn-on temperature is T2, shutdown temperature is T4; After refrigerator compartment temperature generation defrost skew; refrigerator compartment temperature is offset to T0 from T1 before defrost; between room first time start refrigeration after; between room temperature-sensing probe temperature reach after break point T4 between room stop refrigeration; to between after room temperature-sensing probe goes back up to starting point T2, a room starts again refrigeration, so circulates; after the t1 time, compartment temperature returns to the horizontal T1 of stable operation before defrost, and defrost shift duration is t1.
Prior art control law is simple, after refrigerator defrost, when refrigerator compartment temperature is returned to stable operation before defrost by peak excursion temperature state process in, a room refrigeration start-stop still continues control law during room stable operation.
Prior art not for compartment temperature generation defrost after defrost offset this characteristic make corresponding between the control overflow of room refrigeration startup-shutdown, still continue parallel-adder settle-out time room refrigeration startup-shutdown control law.
The maximum shortcoming of prior art is: refrigerator compartment defrost shift duration is longer, and fridge freshness retaining effect is poor.
Summary of the invention
Technical problem to be solved by this invention is, provides one can effectively reduce defrost shift duration, strengthens the controlling method for refrigerator of the fresh-keeping effect of refrigerator.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of controlling method for refrigerator, and it comprises the following steps:
S1. refrigerator compartment design temperature is T1, and between corresponding during stable operation, temperature-sensing probe turn-on temperature in room is T2, shutdown temperature is T4, is adjusted to T5 under being adjusted to T3, shutdown temperature after defrost between corresponding in n1 the cooling cycle closed under the temperature-sensing probe turn-on temperature of room;
S2. after refrigerator compartment temperature generation defrost skew, refrigerator compartment temperature is offset to T0 from T1 before defrost, between room first time start refrigeration after, between do not stop refrigeration after the break point T4 of room temperature-sensing probe temperature when reaching stable operation, continue refrigeration until a room temperature-sensing probe temperature arrive after T5 between room just stop freezing;
S3. stop refrigeration rear until a room temperature-sensing probe temperature recovery is to T3, refrigeration is restarted in a room, until room stops refrigeration between after a room temperature-sensing probe temperature arrival T5;
S4. circularly cooling like this; until after defrost after n1 cooling cycle; between room temperature-sensing probe startup-shutdown temperature return to T2, T4, room refrigeration between control law when refrigerator compartment refrigeration startup-shutdown returns to stable operation continues to control, after the t2 time, compartment temperature returns to T1.
The turn-on temperature lowered and shutdown temperature amplitude are between 0-3 DEG C.
T2, T4 are the startup-shutdown temperature of refrigerator compartment in addition, according to room between different and different between its value of room design temperature fluctuate within the specific limits.
As for freezer compartment of refrigerator, refrigerating chamber design temperature is-18 DEG C, and its turn-on temperature T2 is generally at-17 ± 0.5 DEG C, and its shutdown temperature T4 is generally at-19 ± 0.5 DEG C.In a word T2, T4 and corresponding refrigerator compartment and between this design temperature of room relevant, also given with each manufacturer predefined parameter is relevant.
Compared with prior art, the invention has the beneficial effects as follows:
