Evaporator deicing cover device for freezer {EVAPORATOR DEFROSTING COVER DEVICE OF REFRIGERATOR}

The present invention is designed to prevent frost and ice from being melted by the heater in the freezer's evaporator installed in a low temperature freezer, to prevent heat and steam from being discharged to the refrigerating chamber during defrosting and deicing. The present invention relates to an evaporator ice making cover device of a refrigerator, and the applicant's utility model registration further improves the ice making device of a refrigerator of No. 129519.

Applicant's registration utility model is fixed to the freezer compartment 1, the case 7, the drip tray plate 4 is fixed, the inlet 701 and the outlet 702, as shown in Figure 3, several in the case 7 The coolant pipe 10 is zigzagly piped to the cold air radiating plate 9 of the heat exchanger, and the evaporator 8 and the fan 13 are installed by piping the heat-transfer pipe 12 with the nichrome wire 11 fitted therein, and the cold air If a lot of frost or ice freezes between the diverging plate (9), the freezer is stopped and the heat pipe (12) is heated to melt frost or ice so that the cold air circulation is performed smoothly, which is caused by the heat of the heat pipe (12). As the ice melts, the defrosting and deicing are not performed satisfactorily due to the loss of heat released from the heat and water vapor to the freezing chamber 1 through the inlet 701 as shown in FIG. (1) Frozen because the temperature in it rises There has been a problem that the rate of fall.

The present invention is to solve the above problems, the evaporator (8) by piping the heat transfer pipe (12) in which the refrigerant pipe (10) is zigzag pipe and the nichrome wire (11) inserted in a plurality of cold air diverging plate (9) The heat loss prevention cover 15 having the drainage passage 15 'formed at the lower end at the inlet 702 of the case 7 fixed to the inlet 702 is fixed to the cold air dissipation plate 9 by the heat of the heat transfer pipe 12. When melting the ice to prevent the loss of heat flowing into the freezer compartment 1 through the inlet 701 of the case (7) to prevent the loss of frost and ice to improve the efficiency of the freezer (1) This is to prevent the deterioration of the stored product by increasing the temperature of).

As shown in Figs.

Outside the freezer compartment 1, a compressor 3, a condenser 4, an expansion valve 5, and a freezer 2 having a fan 6 are installed, and inside the freezer compartment 1, an inlet 701 and an outlet ( The case 7 having the 702 formed thereon is fixed, and the heat transfer pipe 12 in which the coolant pipe 10 is zigzagly piped in the case 7 and the nichrome wire 11 is fitted into the cold air diverging plate 9. In that the evaporator 8 and the fan 13 which were piped were installed, and the drip board 14 was fixed to the lower part of the case 7,

The inlet 701 is fixed to the heat loss prevention cover 15 having the drainage passage 15 'formed at the lower end, but the heater 15 may be installed in the drainage passage 15'.

Reference numeral 16 is a drain pipe.

According to the present invention, when the refrigerator 2 is operated, the refrigerant compressed by the compressor 3 is dissipated from the heat of the condenser 4 by the blowing of the fan 6 and the inlet 701 by the fan 13. And the air in the freezer compartment 1 circulated to the outlet 702 is cooled by the cold refrigerant in the evaporator 8 so that the temperature in the freezer compartment 1 becomes gradually low, as in the prior art. When the frost or ice sticks between several cold air diverging plates 9 fixed to the evaporator 8 by operation, and the air circulation is not smoothly performed between the cold air diverging plates 9, the operation of the freezer 2 is stopped. And heat the heat transfer pipe 12 to melt the ice, drain it through the drain pipe 16 of the drip plate 14, and then operate the freezer again to cool the temperature of the freezer compartment 1 to a low temperature. Inlet 701 of the case 7 as shown in FIG. Is fixed to the heat loss prevention cover 15 formed a drainage passage (15 ') at the lower end, so that frost or ice melts by the heat of the heat transfer pipe (12), the steam containing heat through the freezing chamber (1) through the inlet (701) It can be prevented from moving toward the side to prevent the loss of heat can be prevented that the freezing efficiency due to the rapid recording of the ice and the temperature of the freezer compartment 1 rises at the same time.

And the water vapor that is in contact with the inner surface of the heat loss prevention cover 15 is cooled by water droplets and flows down to fall to the drip plate 14 through the drainage path (15 ').

As described above, by preventing heat and steam from leaking into the freezing chamber 1, the cost of electricity can be drastically reduced by shortening defrosting and ice-making time for melting frost or ice, and icicles and floors caused by water vapor. The prevention of freezing and the like can maintain the cleanliness of the freezer compartment and the stored articles in good storage conditions, and prevent the deterioration of the stocks by maintaining a good low temperature of the freezer compartment 1.

The present invention as described above secures the heat loss prevention cover 15 having the drainage passage 15 'formed at the inlet 701 of the case 7 in which the evaporator 8 is installed, thereby dissipating cold air by the heat of the heat transfer pipe 12. When melting frozen frost or ice on the plate 9, heat and water vapor can be prevented from leaking into the freezer compartment 1 through the inlet 701 of the case 7 so that frost or ice can be quickly melted by preventing loss of heat. In addition, it is possible to prevent the temperature of the freezer compartment 1 from rising due to the prevention of heat and vapor leakage, thereby preventing the article stored in the freezer compartment 1 from being deteriorated.
