In this embodiment, the defrost temperature of alternating temperature vaporizer is measured in real time by defrosting sensor 306, when determining defrost
When temperature is more than or equal to 0 DEG C, blower fan 310 will be activated so that the heat that the heating of defrost heater strip distributes can be at temperature-changing chamber
Interior circulation；The temperature of temperature-changing chamber is measured in real time, when the temperature of temperature-changing chamber sets more than or equal to temperature-changing chamber by temperature sensor 308
When the time of temperature is more than first scheduled time, blower fan 310 is closed, and the heating of defrost heater strip 304 simultaneously is also turned off, this
Time, temperature-changing chamber 302 normally will freeze with the temperature set.
Fig. 3 b shows the schematic block diagram of the temperature-changing chamber included by refrigerator according to an embodiment of the invention.
As shown in Figure 3 b, the temperature-changing chamber 302 included by refrigerator according to an embodiment of the invention, including: alternating temperature steams
Send out device 3022.
In this embodiment, after the temperature of temperature-changing chamber 302 reaches the refrigerated storage temperature set, temperature-changing chamber is with design temperature just
Often refrigeration, now, absorbs the heat of food in temperature-changing chamber by alternating temperature vaporizer 3022, refrigerant liquid is evaporated to cold-producing medium
Saturated vapor reaches the effect of refrigeration.Meanwhile, by measuring the defrost temperature of alternating temperature vaporizer 3022, it is possible to judge accurately
The startup time of blower fan.
Fig. 4 shows refrigerator design sketch according to an embodiment of the invention.
As shown in Figure 4, refrigerator according to an embodiment of the invention, at least include following parts: alternating temperature vaporizer
402, alternating temperature sensor 404, alternating temperature blower fan 406, alternating temperature defrosting sensor 408, alternating temperature defrost heater strip 410, zero in Fig. 4
Part and the virtual bench one_to_one corresponding shown in Fig. 3 a, 3b.
Refrigerator according to an embodiment of the invention, alternating temperature sensor 404 is for measuring the temperature of temperature-changing chamber, and alternating temperature defrost passes
Sensor 408 for measuring the defrost temperature of alternating temperature vaporizer 402, temperature-changing chamber from freezing function be converted to cold storage function time
Waiting, the refrigeration of temperature-changing chamber will be stopped, and the heating function of alternating temperature defrost heater strip 410 is unlocked, and is more than in defrost temperature
In 0 DEG C, open alternating temperature blower fan 406 so that the heat that defrost heater strip distributes can accelerate change quickly in alternating temperature indoor circulation
The speed of rising again in greenhouse, be rapidly achieved refrigerated storage temperature, thus improve the work efficiency of refrigerator, it is to avoid has the ice of alternating temperature function
Case is when freezing function is converted to cold storage function, the most oversize, wastes electricity, is unfavorable for the problem that food preserves, and promotes user
Comfort.
Technical scheme being described in detail above in association with accompanying drawing, the present invention proposes the control method of a kind of refrigerator
With a kind of refrigerator so that there is the refrigerator of temperature-changing chamber when temperature-changing chamber is converted to cold storage function by freezing function, become by stopping
The refrigeration in greenhouse, opens the heating of defrost heater strip, accelerates the speed of rising again of temperature-changing chamber, be rapidly achieved refrigerated storage temperature, improves
The work efficiency of refrigerator, it is to avoid have the refrigerator of alternating temperature function when freezing function is converted to cold storage function, the longest, wave
Take energy consumption, be unfavorable for the problem that food preserves, promote user's comfort.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
Change, equivalent, improvement etc., should be included within the scope of the present invention.
