Abstract
The invention discloses an intelligent defrosting control method of a refrigerator. The intelligent defrosting control method comprises the following steps: installing a temperature sensor on an evaporator of the refrigerator, programming a program for the defrosting control process of the evaporator, wherein the program is fixed in a SCM on the refrigerator control panel, the electric heating time of the evaporator and the continuously accumulated run time of a compressor constitute a functional relationship in the program and adjustable parameter K is provided; and simultaneously detecting the defrosting time parameter of the evaporator surface, the total accumulated run time parameter of the compressor and the number of door-opening, and continuously adjusting defrosting time. By adopting the method of the invention, the refrigeration efficiency of the refrigerator is increased, the increased energy consumption caused by frequent heating for defrosting is reduced and the energy-saving rate is over 10%.
Description
Technical field:
The present invention relates to frost-free refrigerator-freezer, relate in particular to a kind of control method of refrigerator intelligent defrosting.
Background technology:
Because the frost-free refrigerator-freezer evaporimeter adopts finned design, after operation a period of time, evaporator surface regular meeting amasss the frosting layer, can have a strong impact on refrigerator refrigeration heat exchange effect as untimely removing, and the refrigerator refrigeration performance descends even can't operate as normal.What at present frost-free refrigerator-freezer adopted is regularly defrost control substantially, and promptly compressor cooling moves to shut down after the stipulated time and enters the pressure defrost, but refrigerator moves different with user's day door opening times under different operating modes, and frosting time and frosting degree are all different; Regularly defrost might be when defrost the evaporator surface frosting seldom, therefore the phenomenon of " frostless defrost " appears in above-mentioned defrosting control method easily, certainly will cause the waste of the energy, increases the energy consumption of refrigerator.In addition, another defective of said method is at wet season, and user's door opening times increases and causes the serious frosting of evaporimeter to cause the air channel to be stopped up and do not arrive the regulation defrost during time, will have a strong impact on the refrigerator refrigeration performance.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of can when evaporimeter frost lamination is poly-, in time the defrosting, when frostless, do not make invalid Defrost operation again, and can guarantee the control method of a kind of intelligent defrosting that each defrosting effect is good, the method is finished the refrigerator defrost process by the defrost program, rather than decides the defrost time by compressor operating time.
Technical solution problem of the present invention adopts following technical scheme:
The control method of refrigerator intelligent defrosting may further comprise the steps:
The first step, on refrigerating evaporator, arrange a temperature sensor;
The program of second step, establishment refrigerating evaporator defrost control procedure, in the single-chip microcomputer of this program Solidification on the refrigerator control panel, programme according to the following steps:
A, timer is set, the cooling time of accumulative total refrigerating evaporator;
The actual first cooling time accumulative total of B, refrigerating evaporator reaches the frosting time T

Compared with the prior art, beneficial effect of the present invention is embodied in:
The control method of refrigerator intelligent defrosting of the present invention is by the temperature after gathering the evaporimeter defrost at refrigerating evaporator surface arrangement temperature sensor, write the intelligent defrosting control program by single-chip microcomputer, the defrost of each defrost periods is compared heat time heating time, accurately judge the degree of evaporator surface frosting, when Based Intelligent Control begins defrosting and when stops defrosting, therefore improved the refrigerating efficiency of refrigerator operation, reduce refrigerator because the energy consumption that the heating defrosting frequently causes rises, energy-saving efficiency reaches more than 10%.
Description of drawings:
Fig. 1 is the control program flow chart of the inventive method.
Below pass through the specific embodiment, and the invention will be further described in conjunction with the accompanying drawings.
The specific embodiment, non-limiting examples is as described below:
Embodiment: referring to Fig. 1, the control method of refrigerator intelligent defrosting of the present invention is to may further comprise the steps when refrigerator is used:
The first step, on refrigerating evaporator, arrange a temperature sensor;
The program of second step, establishment refrigerating evaporator defrost control procedure, in the single-chip microcomputer of this program Solidification on the refrigerator control panel, programme according to the following steps:
A, timer is set, the cooling time of accumulative total refrigerating evaporator;
The actual first cooling time accumulative total of B, refrigerating evaporator reaches the frosting time T
AHour, when arbitrarily small (initial set value can for) be then connected freezing defrost relay and begun defrosting;
If C, whenever is the detected temperature of temperature sensor 〉=zero clearing temperature t

When G, defrost if at strong break time T
D2In minute, if the detected temperature of temperature sensor can not reach and stop the temperature t that defrosts
Df, then force to stop defrost, and set next frosting time T
ABe 8 hours, enter step D afterwards.
Below provide freezing defrost initial value range parameter table (visual test case is adjusted):
| The zero clearing temperature t da | Stop the temperature t that defrosts df | Basic defrosting time T d | Strong break time T d2 |
| ??2~10℃ | ??5~15℃ | 12 ~ 25 minutes | 20 ~ 30 minutes |
Controlling party ratio juris of the present invention is:
1 arranges a temperature sensor on the refrigerator refrigerating evaporator, this temperature sensor is made up of negative tempperature coefficient thermistor, this sensor electrical resistance will change when the evaporator surface temperature changes, and the mode by digital-to-analogue conversion can obtain instant evaporator surface temperature.
2 in the refrigerator control program, a functional relation that continues to add up and form running time by the electrical heating time and the compressor of evaporimeter, and provide adjustable coefficient parameter K.The basic principle that adopts is, evaporimeter amasss the thickness of frosting layer and has certain functional relation between the used time of defrost, and have certain functional relation between the total time of the thickness of long-pending frosting layer and the operation of compressor accumulative total and the door opening times, and above functional equation can simply arrive the tie-in equation between evaporator surface defrosting time parameter and compressor accumulative total total run time parameter and the door opening times parameter.
3 in the intelligent defrosting program, by evaporator surface defrosting time parameter and compressor accumulative total total run time parameter and door opening times parameter are detected simultaneously, thereby and constantly the frosting time is adjusted and realizes intelligent defrosting.The defrost temperature sensor is arranged on the evaporimeter, detects the evaporator surface temperature constantly, by with the defrosting time of last time and basic defrosting time relatively after, accurately judge the frosting situation of evaporimeter, and adjust the frosting time automatically, and accomplished just defrost of frost, frostization is intact promptly stops.
