Abstract
The present invention relates to a low temperature drive and control method of an electronic refrigerator, which comprises a first stage, a second stage and a third stage, wherein the first stage can be used for detecting the ambient temperature of the refrigerator, and thereby, whether the ambient temperature is low or high is judged. If a result judged to be low temperature, whether a compressor lies in operation or not is judged. If the compressor lies in the operation, a low temperature lamp is turned off. If the compressor does not lie in the operation, the low temperature lamp is turned on, the temperature of a freezing chamber of the refrigerator is detected, and the second stage is carried out. When the temperature of the freezing chamber of the refrigerator is detected, the temperature is judged for whether the temperature satisfies conditions or not. If the conditions are not satisfied, the compressor and a fan electromotor are turned on. If the conditions are satisfied, the compressor and the fan electromotor are turned off, and the third stage is carried out. The present invention judges the ambient temperature of the refrigerator through a microcomputer. If the ambient temperature of the refrigerator lies in a low temperature state, the microcomputer can send out heat generating instructions towards the low temperature lamp in the freezing chamber, and thereby, the temperature in the freezing chamber rises. In this way, the refrigerator is turned on newly, and a problem that food in the freezing chamber is metamorphosed because of temperature rise can be solved.

The specific embodiment
As shown in Figure 4, low temperature drive control method for electronic refrigerator of the present invention comprises and detects the refrigerator environment temperature, thereby judges that environment temperature is lower than the temperature that the user sets or is higher than the phase I S41-S42 of the temperature that the user sets; If being environment temperature, the judged result in S42 stage is lower than user's design temperature, judge then whether compressor 6 is in the middle of the operation, if compressor 6 is in the middle of the operation low temperature lamp 9 in the closing cold room then, if compressor 6 is not then opened the indoor low temperature lamp 9 of refrigeration in the middle of operation, and detect the second stage S43-S47 of temperature of refrigerating chamber in refrigerator; Judge when detecting temperature of refrigerating chamber in refrigerator whether it satisfies the temperature conditions that the user sets, just do not open compressor 6 and fan electromotor 7 if do not satisfy the temperature conditions that the user sets, if satisfy the then phase III S48-S50 of close compressor 6 and fan electromotor 7 of temperature conditions that the user sets; Be higher than user's design temperature if the judged result in S42 stage is an environment temperature, then detect the temperature of cold compartment of refrigerator, and judge whether temperature of refrigerating chamber satisfies the quadravalence section S51-S52 of user's design temperature condition; With if the judged result in S52 stage is a temperature of refrigerating chamber not to be satisfied user's design temperature condition and just opens compressor 6 and fan electromotor 7, if satisfy the then five-stage S53-S54 of close compressor 6 and fan electromotor 7 of user's design temperature condition.Referring to Fig. 3, the temperature that electronic refrigerator of the present invention can be regulated refrigerating chamber according to the temperature that the user sets, and judge whether needs drive compression machine 6 and fan electromotor 7 according to detected environment temperature, thus refrigerator is remained under the suitable temperature.With the high temperature of refrigerating chamber of user's frequency of utilization is that to come drive compression machine 6 and fan electromotor 7 be a kind of type of cooling of practicality to benchmark for the user.Microcomputer 1 can be judged the selected Current Temperatures set condition of user that is transmitted by temperature setting portion 2 by the adjustment input circuit, thereby detect detecting means 3 one side drive compressors 6 and fan electromotor 7 at temperature of refrigerating chamber, so that the temperature of refrigerating chamber meets the demands.At this moment, impose a condition if the temperature of refrigerating chamber satisfies, microcomputer 1 just can stop the operation of compressor 6 and fan electromotor 7.Like this, refrigerator is carried out said process repeatedly, thereby keeps the temperature of refrigerating chamber and refrigerating chamber certain.But when weather is very cold in the winter time; the refrigerating chamber internal temperature situation close or identical with environment temperature promptly appears; in this state; the temperature of refrigerating chamber just can not rise again; thereby refrigerator is also just no longer worked; but the temperature of refrigerating chamber then can be shut down sharply because of refrigerator and be risen, thereby causes the food spoilage of keeping in the refrigerating chamber.Therefore, consider the situation that environment temperature descends, electronic refrigerator of the present invention can utilize external temperature to detect the external temperature that detecting means 4 detects refrigerator, and microcomputer 1 will send the heating instruction by the low temperature lamp 9 in refrigerating chamber when external temperature drops to user's design temperature.9 work when compressor 6 does not move of low temperature lamp.Promptly, when externally temperature detection detecting means 4 detects the refrigerator environment temperature, if detected refrigerator environment temperature is lower than user's design temperature, should judge the duty of compressor 6 with that, if compressor 6 is just should cut out low temperature lamp 9 in the middle of operation; Can open low temperature lamp 9 if compressor 6 does not move and make its heating.But, from refrigerator, take out food and when opening refrigerating-chamber door the user, can stop the work of low temperature lamp 9 by door test section 5, and microcomputer 1 can send the instruction of opening ordinary lamps 8.This control procedure returns to more than user's design temperature up to refrigerator temperature on every side repeatedly, and the control circuit of low temperature lamp 9 will quit work.Then, be after being lower than user's design temperature or being higher than user's design temperature state, to enter into the corresponding work process by judgement refrigerator external temperature, thereby keep refrigerating chamber and refrigerating chamber under suitable temperature.
