Abstract
The present invention relates to processing method and the device of the inefficacy of a kind of refrigerator probe, when environment temperature probe lost efficacy, being defaulted as environment temperature was 25 DEG C; When environment temperature probe is intact, when a certain room or multiple compartment temperature probe lost efficacy, the height of processor of single chip computer environmentally temperature runs compressor and associated magnetic valve to each room according to rational start/stop time, controls a more rational scope to realize compartment temperature.Method of the present invention has following benefit: even if when having one or more probe to lose efficacy, and the temperature of refrigerator can also control, in a more satisfactory temperature range, to make the article be stored in case keep fresh state within a certain period of time.
Description
Technical field
The present invention relates to refrigerator control field, refer in particular to processing method and the device of the inefficacy of a kind of refrigerator probe.
Background technology
Fig. 1 is the testing circuit of conventional refrigerator probe, and by connecting, one or more resistance is converted into voltage signal the resistance signal of probe, is input to the A/D mouth of single-chip microcomputer.Temp probe is used to the device gathering actual temperature in refrigerator, and between general one, at least should there be more than one temp probe room, is one of most important device during refrigerator normally runs.
But some reasons may cause probe to lose efficacy below: 1, easily crack under the long-time at low temperatures cold cycling environment of sensing connecting line, namely can infiltrate temperature-sensing element along wire cause sensor temperature sensing device Parameters variation as cracked moisture; 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 probe breaks down, whole refrigerator may be caused normally not run or to run and make mistakes, the article be stored at like this in refrigerator just degenerate very soon, before refrigerator maintenance, bring loss to user.
