Abstract

PROBLEM TO BE SOLVED: To simply detachably attach a heat insulating cover to a cooler. SOLUTION: Notched grooves 41 and 46 opened to a lower edge are provided in the front surface of a heat insulating cover 9 composed of a heat insulating box member whose lower surface is opened. The notched grooves 41 and 46 comprise a pipe line fitting part 42 and a pipe fitting part 47, and block member fitting parts 43 and 48 which are disposed below them and wider the them and to which resilient block members 44 and 49 can be fitted. In the block member fitting parts 43 and 48, the notched width of inner boxes is narrowed and stoppers 45 and 50 are formed so that the block members 44 and 49 are prevented from passing through to a rear side. For attaching the heat insulating cover 9 to a cooler, while the heat insulating tube 21 of a pipeline and a drain pipe 29 connected to the cooler 8 are inserted into the notched grooves 41 and 46, the cooler 8 is covered with the heat insulating cover 9. Then, the block members 44 and 49 are fitted into the grooves. For detaching the heat insulating cover 9 from the cooler 8, after the block members 44 and 49 are removed from the grooves, the heat insulating tube 21 and the drain pipe 29 are pulled out of the opening edges of the notched grooves 41 and 46 and then, the heat insulating cover 9 is pulled upward.

2. Description of the Related Art In a refrigerator, it is more advantageous to provide a cooler outside the refrigerator in order to increase the internal volume of the refrigerator. In that case, since it is necessary to provide the cooler and the cool air passage so as to be insulated from the outside air, it is necessary to cover the cooler with a heat insulating cover. Since the cooler is connected to the condensation unit side by piping to form a refrigeration cycle,
When the heat insulating cover is covered, the cooling pipes taken in and out of the cooler are pierced through the heat insulating cover. On the other hand, a cooler and defrost-related parts attached to it,
Since the internal fan etc. requires maintenance, the heat insulating cover must be removable. In short, the heat insulating cover must be capable of penetrating the cooling pipe that is taken in and out of the cooler in an airtight state and being removable at the time of mounting.

While the refrigerant flows through the cooler 8 and the cooling action is occurring, the internal fan 27 is operated so that the air in the refrigerating chamber 4 is removed as shown by the arrow in FIG. The cool air that has been sucked to the front side of the cooler 8 through the duct 25 and has undergone heat exchange through the cooler 8 is the cool air outlet 26.
Is blown out from the refrigerator to the refrigerating chamber 4 side, and cold air is circulated and supplied into the refrigerator. During this time, since the high-temperature refrigerant flows through the cooling pipe 18 provided in the evaporation dish 16, the defrosted water stored in the evaporation dish 16 is evaporated by the heat. At the same time, when the condenser fan 14 is driven, the outside air is sucked through the ventilation port 30 to cool the condenser 13, and a part of the warm exhaust after the heat exchange becomes defrost water in the evaporation tray 16. It is sprayed to accelerate its evaporation.

When performing maintenance on the cooler 8, the defrosting parts attached thereto, the internal fan 27, etc., the heat insulating cover 9 is removed, which is carried out as follows. First, each closing body 44, 49 is pulled out toward the front side to be removed from the closing body fitting portion 43, 48, and then the screw 39 of the bracket 35 is loosened and removed. After that, when the heat insulating cover 9 is pulled upward, the closing body fitting portions 43 and 48 of the respective cutout grooves 41 and 46 are opened, so that the cooling pipe 19,
20 and the drain pipe 29 are notched grooves 41, 46.
The heat insulating cover 9 is removed while pulling out from the opening at the lower end of the. As a result, the cooler 8 and the like are exposed to the outside, and maintenance can be subsequently performed.
