Abstract
The utility model belongs to the technical field of refrigerators in electrical equipment, and in particular relates to a defrosting control device of an air cooling refrigerator evaporator. The defrosting control device of the air cooling refrigerator evaporator comprises a defrosting heater connected with a refrigerator main control panel and a defrosting sensor, the defrosting heater and the defrosting sensor are both connected with an evaporator. The defrosting control device adopts defrosting heater for clearance heating so as to control defrosting of the refrigerator evaporator, thereby reducing the heat brought in the refrigerator through defrosting electrical heating, improving defrosting efficiency and reducing energy consumption.
Description
Technical field
The utility model belongs to refrigerator technical field in the electric equipment, particularly a kind of wind cooling refrigerator evaporimeter defrost control device.
Background technology
Wind cooling refrigerator is commonly called as frost-free refrigerator, and the frost of tying on the evaporimeter leans on electrical heating heating automatic defrosting, and does not need artificial defrosting.
Frosting process: start compressor, evaporimeter refrigeration, the water vapour in the respiratory box; Form the thin frost of one deck earlier at evaporator surface; Through start-stop refrigeration after a while, the frost layer thickening of evaporimeter is full of the gap between whole evaporator fin; Need to remove the frost on the evaporimeter this moment, refrigerator could operate as normal.Compressor quits work, and electrical heating is heated automatically, and the frost that always is heated on the evaporimeter does not have, and after stopping to heat a few minutes, compressor restarts refrigeration again.
Like Fig. 2, be the connection sketch map of mechanical defroster, mechanical defroster is exactly a time timer,
Compressor and defrost electric heater simultaneously can only parts job; In defrost timer timing course; That road of conducting compressor; When timer is accumulated to setting-up time (cumulative time is confirmed by timer parameter), the defrost electrical heating starts, and heats a period of time to get into the next refrigeration cycle after (time length is confirmed by timer parameter) withdraws from defrost always.
The defrost electric heater is worked always during heating, finishes until defrost.Adopt this mode defrost, consume very big energy consumption, and efficient is not high.
The utility model content
The problem that the utility model will solve provides a kind of wind cooling refrigerator evaporimeter defrost control device, and this device utilizes defrost electric heater surface waste heat to come heating fumigators to carry out defrost, to improve defrost efficient, cuts down the consumption of energy.
For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of wind cooling refrigerator evaporimeter defrost control device; This defrost control device comprises defrosting heater and the defrosting sensor that is connected with the refrigerator master board, and said defrosting heater all is connected with evaporimeter with defrosting sensor.
Further, defrost relay and timer that said master board comprises chip, is connected with chip, said defrosting heater is connected with chip through the defrost relay, and said defrosting sensor is connected with chip.
Compared with prior art, the utlity model has following beneficial effect:
The utility model adopts the defrost of defrost electric heater gap heating with the control evaporator of refrigerator, reduces the heat in the defrost electrical heating heating tape cartonning, improves defrost efficient, cuts down the consumption of energy.
Description of drawings
Fig. 1 is the block diagram of the utility model defrost control device;
Fig. 2 is the connection sketch map of prior art machinery defroster.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is carried out detailed description.
As shown in Figure 1, the utility model discloses a kind of wind cooling refrigerator evaporimeter defrost control device, it comprises defrosting heater and the defrosting sensor that is connected with the refrigerator master board, said defrosting heater all is connected with evaporimeter with defrosting sensor.
Particularly, defrost relay and timer that master board comprises chip, is connected with chip, said defrosting heater is connected with chip through the defrost relay, and said defrosting sensor is connected with chip.
The course of work of the utility model wind cooling refrigerator evaporimeter defrost control device is:
During the refrigerator refrigeration, timer picks up counting, and after refrigerator reached uniform temperature, compressor quit work, and when temperature rose to setting value in the refrigerator, compressor was started working again, and compressor stops again after work a period of time, and compressor one heads straight for the work that start-stop stops like this.When timer timing chip behind the certain hour sends the order of defrost, get into defrost periods;
When program, get into defrost periods, chip sends the defrost instruction, the conducting of defrost relay, and electric heater begins heating, and the timer on the mainboard picks up counting; When timing behind 5min, chip sends instruction, breaks off the defrost relay, reclocking after timer zero clearing when breaking off relay; When timing behind 1min, chip sends defrost instruction, the conducting of defrost relay, electric heater begins heating, reclocking after the timer zero clearing in the time of the relay conducting; When timing chip behind the 2min sends instruction, break off the defrost relay, reclocking after timer zero clearing when breaking off relay; When timing behind 1min, chip sends defrost instruction, the conducting of defrost relay, electric heater begins heating, reclocking after the timer zero clearing in the time of the relay conducting; When timing chip behind the 2min sends instruction, break off the defrost relay, reclocking after timer zero clearing when breaking off relay; The heating of this gap is until defrost temperature-sensitive sensor reaches the condition that withdraws from defrost.
Claims (2)
1. wind cooling refrigerator evaporimeter defrost control device, it is characterized in that: comprise the defrosting heater and the defrosting sensor that are connected with the refrigerator master board, said defrosting heater all is connected with evaporimeter with defrosting sensor.
2. wind cooling refrigerator evaporimeter defrost control device according to claim 1; It is characterized in that: defrost relay and timer that said master board comprises chip, is connected with chip; Said defrosting heater is connected with chip through the defrost relay, and said defrosting sensor is connected with chip.
