Abstract
The utility model relates to a defrosting control system of an air cooling refrigerator. The defrosting control system comprises a defrosting heater (1), a finned evaporator (2), a water pan and a water pan heater (3), wherein the defrosting heater (1) is embedded onto the finned evaporator (2); the water pan heater (3) is fixed on the surface of the water pan; and the finned evaporator (2) is provided with a temperature sensor. When a refrigerator achieves the defrosting requirements, the defrosting heater (1) is opened, and then the water pan heater (3) is opened after the time is delayed to n1; and when the temperature of the temperature sensor on the finned evaporator (2) achieves the preset temperature value, the defrosting heater (1) is closed, and meanwhile, the water pan heater (3) is closed after the time is delayer to n2. With the adoption of the defrosting control system of the air cooling refrigerator, the water pan is defrosted through controlling delayed opening and closing of the water pan heater (3), so that the defrosting efficiency is improved, the energy consumption is lowered, and the condition that a drain pipe is blocked by ice is solved thoroughly.
Description
Technical field
The utility model belongs to the refrigerator equipment technical field, particularly a kind of wind cooling refrigerator defrosting control system.
Background technology
Wind cooling refrigerator is commonly called as frost-free refrigerator, and the frost of tying on the evaporimeter leans on Defrost heater heating automatic defrosting, and does not need artificial defrosting.
Defrost system in the wind cooling refrigerator generally comprises: parts such as evaporimeter, Defrost heater, defrost controller, high temperature fuse, drip tray, drip tray heater, drainpipe are formed.
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.
Defrost process: compressor quits work, and Defrost heater and drip tray heater heat automatically, is heated to after frost on the evaporimeter melts always, stops heating, and the water of defrost is simultaneously discharged through drainpipe by drip tray, and after a few minutes, compressor restarts refrigeration again.
Owing to have the part trash ice to fall and be deposited in around drip tray and the drainpipe on the evaporimeter in the defrost process; Thereby cause drainpipe ice stifled; Want complete defrost and solve the stifled problem of drainpipe ice, the heat time heating time of can only extend Defrost heater and drip tray heater.The synchronous start-stop of drip tray heater and Defrost heater can increase the whole energy consumption of refrigerator like this.
The utility model content
The problem that the utility model will solve is to provide a kind of to the deficiency of prior art and can reduce the whole energy consumption of refrigerator, thoroughly solve the wind cooling refrigerator defrosting control system of the stifled problem of drip tray ice.
For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of wind cooling refrigerator defrosting control system; Comprise defrosting heater, evaporator fin, drip tray and drip tray heater; Said defrosting heater embeds and is installed on the evaporator fin, and the drip tray heater is the surface of drip tray fixedly, and said evaporator fin is provided with temperature sensor.
Further, said drip tray heater sticks on the drip tray through aluminium foil.
Compared with prior art, the utlity model has following beneficial effect:
It is residual that drip tray and discharge outlet have a large amount of trash ices in the prior art.After adopting the present invention, drip tray and thoroughization of discharge outlet trash ice are clean.The utility model increases temperature sensor, and the time-delay start-stop of control drip tray heater defrosts to drip tray, improves defrost efficient, cut down the consumption of energy, and it is stifled thoroughly to solve drainpipe ice.
Description of drawings
Fig. 1 looks sketch map for the utility model master;
Fig. 2 is the utility model schematic side view.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is carried out detailed description.
Like Fig. 1, shown in Figure 2; The utility model discloses a kind of wind cooling refrigerator defrosting control system; Comprise defrosting heater 1, evaporator fin 2, drip tray 4 and drip tray heater 3, defrosting heater 1 embeds and is installed on the evaporator fin 2, and evaporator fin is provided with temperature sensor.Drip tray heater 3 usefulness aluminium foils are pasted on the surface of drip tray 4.
The control flow of the utility model wind cooling refrigerator defrosting control system is: when refrigerator reaches the defrost requirement; Open defrosting heater 1; Delay time and open drip tray heater 3 again after n1 minute; When the temperature sensor on the evaporator fin reaches setting value, close defrosting heater 1, closed drip tray heater 3 after delaying time simultaneously n2 minute.
N1=n2 generally speaking, in particular cases n1 also can be not equal to n2, needs to decide with border situation factually, and n1 and n2 generally are no more than 10 minutes.
Time-delay start-stop drip tray heater can cut down the consumption of energy, and thoroughly solves the stifled problem of drainpipe ice.
Claims (2)
1. wind cooling refrigerator defrosting control system; Comprise defrosting heater (1), evaporator fin (2), drip tray (4) and drip tray heater (3); Said defrosting heater (1) embeds and is installed on the evaporator fin (2); Drip tray heater (3) is fixed on the surface of drip tray (4), it is characterized in that: said evaporator fin (2) is provided with temperature sensor.
2. wind cooling refrigerator defrosting control system according to claim 1 is characterized in that: said drip tray heater (3) sticks on the drip tray (4) through aluminium foil.
