Description

[Detailed description of the invention] The invention relates to a refrigerator having an indirect cooling type vegetable compartment.
This relates to a system that uses part of the refrigerant piping on the high-pressure side of the refrigeration cycle to prevent freezing on the outer surface of the partition wall between the freezer compartment, refrigerator compartment, and vegetable compartment, and in the duct for cooling the vegetable compartment. .

Conventionally, as shown in Fig. 3, air cooled by a cooler is circulated through a duct a provided on the top of the vegetable compartment as shown by arrow A, thereby indirectly cooling the vegetable compartment. It is well known that the temperature difference between the inside of the vegetable compartment and the inside of the duct (a) is large, so even though indirect cooling is used, the condensation water that forms on the surface of the cooling plate C freezes, and furthermore, the vegetables freeze. was there.

The present invention eliminates these drawbacks and prevents freezing of condensed water in the vegetable compartment or duct, as well as freezing of vegetables.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a refrigerator body, which is divided by partition walls 2 and 3 into a refrigerator compartment 4 at the top, a vegetable compartment 5 at the lower left, and a freezing compartment 6 at the lower right.

Further, these three chambers are integrally formed by an inner box 1' made of synthetic resin, and a high-pressure side refrigerant pipe 8 of the refrigeration cycle is arranged at the opening periphery 7 and the front back side of the partition walls 2 and 3.

In particular, a high-pressure side refrigerant pipe 9, which is an extension of a part of the high-pressure side refrigerant pipe 8 located in the front part 2' of the vegetable compartment partition wall, is used for cooling to form a duct 1-10 provided along the top surface of the vegetable compartment 5. Board 11
It is located in

Note that the cooling plate 11 is made of an aluminum material or the like having good thermal conductivity.

Next, the effects of the above configuration will be explained.

As shown by arrow B in FIG. 2, cold air enters the duct 10 through the suction hole 12, flows to the discharge hole 13, and circulates.

At this time, since the high-pressure side refrigerant pipe 9 is disposed on the cooling plate 11, the vegetable compartment 5 is cooled by the cold air heated by the refrigerant pipe 9, causing dew condensation on the cooling plate 11 and its It can prevent freezing and even food from freezing.

Therefore, an electric heater or the like is not required, and power consumption can be reduced.

Furthermore, since the duct 10 is formed by arranging the cooling plate 1 inside the inner box 1', it can be drawn out from the pipe 8 located at the front part 2' of the vegetable compartment partition wall outside the inner box 1'. This is extremely convenient and can improve assembly efficiency.

As described above, the refrigerator of the present invention has a refrigerator compartment, a freezer compartment, and a vegetable compartment, and is provided with a duct that cools the outer periphery of the vegetable compartment with cold air without directly introducing cold air into the vegetable compartment. A high-pressure side refrigerant pipe is arranged at the front end of the partition wall that partitions the three compartments and around the opening, and a part of the high-pressure side refrigerant pipe is extended into the duct for cooling the vegetable compartment. The vegetable compartment can be cooled with relatively high-temperature cold air, eliminating the conventional disadvantages of freezing ducts or freezing food, making it an optimal solution. It can be stored for a long time.
