Abstract
The invention relates to a device and method for malfunction treatment of refrigerator probes. The environmental temperature is defaulted to be 25 DEG C when an environmental temperature probe is malfunctioned; when the environmental temperature probe is in good condition but temperature probes in one chamber or more chambers are malfunctioned, a single-chip processor operates a compressor and a relevant electromagnetic valve of each chamber by reasonable on-off time according to environment temperature levels to control the temperature of the chambers within a reasonable range. The method has the advantages that even if one or more probes are malfunctioned, the temperature of a refrigerator can be controlled within a favorable temperature range to enable articles stored in the refrigerator to keep fresh in a certain period.
Description
Technical field
The present invention relates to refrigerator control field, refer in particular to processing method and device that a kind of refrigerator probe lost efficacy.
Background technology
Fig. 1 is the testing circuit of conventional refrigerator probe, by one or more resistance of connecting, the resistance signal of probe is converted into voltage signal, is input to the A/D mouth of single-chip microcomputer.Temp probe is for gathering the device of actual temperature in refrigerator, and between general one, at least should there be an above temp probe chamber, is one of normal most important device in service of refrigerator.
But some reasons may cause probe to lose efficacy below: 1, under the long-time at low temperatures cold cycling environment of sensing connecting line, easily crack, as crack moisture and can infiltrate temperature-sensing element along wire and cause that sensor temperature sensing device parameter changes; 2, probe temperature-sensing element solder joint breaking strain; 3, separated or loose contact in sensor temperature sensing device connecting line; 4, easily aging under the long-time at low temperatures cold cycling environment of plug connector, cause loose contact.Once one or more compartment temperature probes break down, and may cause whole refrigerator normally not move or to move and make mistakes, the article that are stored at like this in refrigerator just degenerate very soon, before refrigerator maintenance, to user, bring loss.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and the processing method and the device that provide a kind of refrigerator probe to lose efficacy.
The object of the invention is to complete by following technical solution.The processing method that this refrigerator probe lost efficacy, when environment temperature probe lost efficacy, being defaulted as environment temperature is 25 ℃; When environment temperature is popped one's head in intact, when a certain chamber or a plurality of compartment temperature probe lost efficacy, processor of single chip computer moves compressor and associated magnetic valve to each chamber according to rational start/stop time according to the height of environment temperature, to realize compartment temperature, be controlled at a more rational scope, specifically control step as follows:
