The refrigeration control method of the refrigerator according to the embodiment of the present invention is described below in conjunction with accompanying drawing 1.
Fig. 1 is the flow chart of the refrigeration control method of refrigerator according to an embodiment of the invention.
As shown in Figure 1, the refrigeration control method of refrigerator according to an embodiment of the invention, wherein, refrigerator comprises and is arranged on its heater indoor between first, and the method comprises the following steps:
Step S101, detects the environment temperature residing for refrigerator, and compares this environment temperature and first threshold.Such as: the current residing environment temperature of refrigerator can be detected with temperature sensor, and compare with the first threshold of preset in advance.
Step S102, if environment temperature is less than or equal to first threshold, then judge whether the compartment temperature of first room is less than Second Threshold, and wherein, Second Threshold is less than first threshold further, and Second Threshold is negative integer.In an embodiment of the present invention, such as: first threshold is but is not limited to 10 DEG C, Second Threshold is but is not limited to-2 DEG C.The refrigerating chamber of first room and refrigerator.In other words, namely when environment temperature is less than or equal to 10 DEG C residing for the refrigerator detected, then judge whether the temperature of cold compartment of refrigerator is less than-2 DEG C further.
Step S103, if the temperature of first room is less than Second Threshold, then starts heater and heats first room.Further, when the temperature of first room is more than or equal to the 3rd threshold value, close heater, wherein, the 3rd threshold value is between first threshold and Second Threshold, and the 3rd threshold value is negative integer, and such as the 3rd threshold value is but is not limited to-1 DEG C.In other words, if when namely judging that the temperature of the refrigerating chamber of refrigerator is less than-2 DEG C, then the heater started in refrigerating chamber carries out heat temperature raising to refrigerating chamber, and when the temperature in refrigerating chamber is more than or equal to-1 DEG C, heater in closing cold room, stops heating up to refrigerating chamber.
Further, as shown in Figure 2, in step s 103, when in the process that startup heater heats first room, further comprising the steps of:
Step S201, if after reaching the first Preset Time the start-up time of heater, how temperature indoor between first all will close heater.Namely, when starting heater and heating up to refrigerating chamber, after the working time after heater starting reaches the first Preset Time, then no matter now whether the temperature of refrigerating chamber is greater than or equal to the 3rd threshold value, all will close heater.Wherein, the first Preset Time presets according to the actual conditions of different refrigerator.
Step S202, judges whether the continuous shut-in time of heater reaches the second Preset Time.Namely, in above-mentioned steps S201, after the heat time reaches the first Preset Time, heater closed by refrigerator, then judge whether the continuous shut-in time of heater reaches the second Preset Time.Wherein, the second Preset Time presets according to the actual conditions of different refrigerator.
Step S203, if reach the second Preset Time, then repeated execution of steps S201 and step S202.Namely after the continuous shut-in time of heater reaches the second Preset Time, repeated execution of steps S201 and step S202.
In the examples described above, first the current residing environment temperature of refrigerator is detected, and compare with first threshold, if be less than or equal to first threshold, then judge refrigerating chamber temperature whether be less than Second Threshold, if the heater then started in refrigerating chamber is to refrigerating chamber heat temperature raising, and when temperature of refrigerating chamber is more than or equal to the 3rd threshold value, close heater, stop heating up.Thus ensure that cold compartment of refrigerator is unaffected when ring temperature is lower, keep normal operating temperature, meet the user demand of user.
In addition, in actual applications, first room in above-mentioned example also can be refrigerating chamber and/or temperature-changing chamber.
According to the refrigeration control method of the refrigerator of the embodiment of the present invention, by increasing a heater to room between refrigerator, when low ring temperature, if compartment temperature is too low, then heater can pair between room carry out temperature-compensating, the temperature making a room, by the impact of ring temperature, reaches the temperature that user needs.
Fig. 3 is the structure chart of refrigerator according to an embodiment of the invention.
As shown in the figure, refrigerator 300 according to an embodiment of the invention, comprising: casing 310, door body 320, heater 330 and controller 340.
Be provided with a room in casing 310, and a room at least comprises room 312 between first room 311 and second.Wherein, first room 311 is refrigerating chamber, and second room 312 is refrigerating chamber.
Door body 320 is arranged on casing 310, in order to open or close room between casing 310.
Heater 330 is arranged in first room 311, is namely arranged in refrigerating chamber, for heating first room 311.
Controller 340 is connected with heater 330, for comparing environment temperature residing for refrigerator 300 and first threshold, and when environment temperature is less than or equal to first threshold, judge whether the compartment temperature of first room 311 is less than Second Threshold further, wherein, Second Threshold is less than first threshold.And control heater 330 starts when the compartment temperature of first room 311 is less than Second Threshold, heat temperature raising is carried out to first room 311.In heating process, real-time detection also judges whether the compartment temperature of first room 311 is more than or equal to the 3rd threshold value, and when compartment temperature is more than or equal to the 3rd threshold value, control heater 330 is closed, wherein, 3rd threshold value is between first threshold and Second Threshold, and Second Threshold and the 3rd threshold value are negative integer.In an embodiment of the present invention, such as: first threshold is but is not limited to 10 DEG C, Second Threshold is but is not limited to-2 DEG C, and the 3rd threshold value is but is not limited to-1 DEG C.
Controller 340 also for after heater 330 starts, in the process heated for first room 311, A; After reaching the first Preset Time the start-up time of heater 330, control heater 330 is closed, and namely no matter now whether the temperature of first room 311 is more than or equal to the 3rd threshold value, all will close heater 330; B: after heater 330 cuts out, judge whether the continuous shut-in time of heater 330 reaches the second Preset Time; If then repeat above-mentioned steps A and step B.Wherein, the first Preset Time and the second Preset Time all preset according to the actual conditions of different refrigerator.
