According to another specific embodiment of the present invention, refrigerator be configured with compressor, blower fan, ring temperature sensor, door trip, Optical sensor or light sensor；Wherein, ring temperature sensor can be positioned in refrigerator doors it is also possible to be placed in the casing of refrigerator On；Optical sensor can be placed on casing it is also possible to be placed on door；The Energy Saving Control process of refrigerator is as follows：

Compressor rotary speed controls：After refrigerator energising, first pass through ring temperature sensor judgement ambient temperature now.By ring Temperature is divided between several ring warm areas (can be defined as differing 5 DEG C between each ring warm area), if be also divided into compressor rotary speed simultaneously Dry gear, a corresponding compressor rotary speed gear between each ring warm area, this rotating speed is as reference rotation speed, if ring temperature often raises 5 DEG C, corresponding compressor rotary speed just rises 1 grade.For example：Tc will be set to, compressor rotary speed gear is set to RPMn between ring warm area, When Tc≤10 DEG C, corresponding compressor rotary speed RPM1=1 shelves, as 10+5 (n-1) ＜ Tc≤10+5n, corresponding compressor turns Speed rises to RPMn=n+1 shelves, and wherein n is the integer more than or equal to 1 less than or equal to 6, compressor reference rotation speed gear≤n+1 Shelves.In addition can detect whether refrigerator opens the door by door trip, adjust the rotating speed of compressor according to testing result.If detection There is door opening action to refrigerator, then compressor rotating speed on original benchmark gear raises one grade, until compressor is shut down naturally, it The benchmark gear controlling before recovering afterwards.Judge that current environment is daytime or evening finally by optical sensor, if in vain My god, compressor rotary speed remains unchanged, if evening, freezer compressor rotating speed can accordingly reduce a rotating speed.

Rotation speed of fan controls：Rotation speed of fan sets two basic rotating speeds, and one of is high rotating speed, and one is the slow-speed of revolution. Set a marginal value (such as 35 DEG C) to ring temperature, when ring temperature is higher than marginal value, blower fan adopts high rotating speed to run；When ring temperature is low When marginal value, blower fan adopts the slow-speed of revolution to run.It can in addition contain whether open the door to control the keying of blower fan according to refrigerator, work as inspection When measuring refrigerator and having door opening action, close blower fan, when detect refrigerator close the door or when the refrigerator open time more than 10 minutes when, It is again turned on blower fan, and adjust to maximum rotation speed of fan gear, until blower fan is shut down naturally, the benchmark of control before recovering afterwards Gear.Judge it is daytime or evening finally by optical sensor, if daytime, rotation speed of fan remains unchanged, if late On, rotation speed of fan can take underdrive operating.

Defrost heater strip controls：Ring temperature is divided between several ring warm areas (each ring temperature section can be defined as differing 5 DEG C), Also the defrost cycle is divided into several cycle gears simultaneously, and between each ring warm area, in a corresponding defrost cycle, then judge 24h again Interior refrigerator adds up door opening times or accumulative opening time, and door opening times often increase by 2 times, and the defrost cycle rises 1 grade；Or ice The accumulative opening time of case often increases 30s, and the corresponding defrost cycle just rises 1 grade.During defrost, compressor and blower fan are turned off Defrost heating wire works, after the completion of defrost, heater strip is closed, and a now defrost completes, and refrigerator open number of times is opened with accumulative Door time whole clearing is processed.The next cycle period of entrance is rejudged after 7 minutes.

In this embodiment, detected by ring temperature sensor and judge current environment residing for refrigerator ambient temperature be located Ambient temperature is interval, and detects refrigerator door open-close action by door trip, and is sentenced by optical sensor or light sensor Disconnected current environment is daytime or night it is achieved that intelligent comprehensive adjusts compressor rotary speed gear, rotation speed of fan gear or control Blower fan opens and closes and defrost cycle gear, so that refrigerator reaches intelligent power saving, both ensure that the storage quality of food in refrigerator, Reduce the noise of refrigerator again, reduce energy loss, lift Consumer's Experience.

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, made any repair Change, equivalent, improvement etc., should be included within the scope of the present invention.
