Description

Ice take-off device of the refrigerator

The present invention relates to an ice extractor of a refrigerator, and in particular, it is possible not only to extract ice without opening the refrigerator door at the time of extracting the ice generated by the automatic ice maker provided in the freezer compartment, but also to thermoelectric the ice extractor. The present invention relates to an ice extractor of a refrigerator having an improved structure to prevent melting of ice by employing an element to compensate for cold air.

In general, the ice extractor of the refrigerator has a structure in which the refrigerator door is opened and the ice is extracted from the ice storage when the ice produced by the ice maker is taken out. This increases not only lowers the cooling efficiency of the refrigerator, but also increases the economic loss such as frequent operation of the compressor motor for cooling the elevated interior caused by the opening of the refrigerator door, thereby increasing power consumption.

In addition, if the refrigerator door is opened every time ice is taken out, the number of opening and closing of the refrigerator door is increased to accelerate the deflection of the refrigerator door and deformation of the gasket, which shortens the life of the refrigerator.

An ice extractor of a refrigerator has been commercialized to solve such a problem, which is illustrated in FIG. 1 as an ice extractor of a conventional refrigerator capable of extracting ice without opening a door of the refrigerator.

Referring to FIG. 1, the ice extractor of the refrigerator includes an ice reservoir 10 in which ice generated by an automatic ice maker is temporarily stored, and an ice extraction door installed at one side of the ice reservoir to remove ice from the ice reservoir 10. 20 and an ice shield plate 40 rotatably coupled by the hinge 30 in the ice reservoir 10 to be opened and closed together with the ice extraction door 20.

The ice extractor of the conventional refrigerator configured as described above holds the handle 21 installed on the ice extractor 20 in the state where the ice extractor 20 is closed and pulls it forward to simultaneously open the ice extractor 20. The ice shielding plate 40 located behind the ice extraction door rotates in the opening direction so that a predetermined amount of ice temporarily stored in the ice storage 10 can be taken out, and after the ice is taken out, the ice extraction door 20 ), The ice shield plate 40 is also rotated in the closing direction.

In addition, the ice shielding plate 40 in the ice extractor of the conventional refrigerator as described above serves to prevent the ice filled in the ice reservoir 10 to flow out of the ice reservoir 10 when the ice extraction door 20 is opened. Do it.

However, the ice extractor of the conventional refrigerator as described above has an ice shield plate 40 by a simple structure in which the hinges 30 formed on both side plates of the ice shield plate 40 are coupled to the hinge grooves of the ice storage 10. Since it is rotatably installed in the ice reservoir 10, ice is caught between the side wall of the ice reservoir 10 and both side plates of the ice shield plate 40, thereby preventing the rotation of the ice shield plate 40, and withdrawing the ice. There is a problem that the opening and closing of the door 20 is not smooth.

In addition, it is inconvenient to take out a large amount of ice because it is necessary to pull out the required amount of ice by holding the door handle 21 and opening the ice extraction door 20 and then inserting a hand into the ice storage 10. And not only takes a lot of time, there is a problem that the hygiene of the ice is poor.

In addition, since the flow rate of the cold air is increased due to the opening and closing of the ice extraction door 20, the cooling efficiency is lowered, and the operation of the compressor motor is frequent, so that the power loss is increased, and the opening time of the ice extraction door 20 is increased. As it becomes longer, the ice melts and becomes tangled with each other, making it difficult to pull out the ice into two pieces, and it is inconvenient to use the ice that is fastened to each other immediately. It is done.

The present invention has been made to solve the above problems, has the following objectives.

First, the object of the present invention is to provide an ice extractor of a refrigerator having an improved structure such that ice can be withdrawn without opening the refrigerator door, thereby reducing ice extraction time and preventing loss of cold air.

Secondly, the upper and lower surfaces of the ice take-out door are formed to communicate with each other, and an object thereof is to provide an ice take-out device of a refrigerator having an improved structure so that the amount of ice can be adjusted according to the opening angle of the ice take-out door. .

Third, the ice is drawn out through the entrance communicating with the upper and lower sides of the ice extraction door, and the freezer compartment is sealed by both sides and front and rear surfaces of the ice extraction door even when the ice extraction door is opened. In addition to improving the cooling efficiency, the operation time of the compressor motor, etc. is shortened to provide an ice extractor of the refrigerator whose structure is improved to reduce the power consumption.

Fourth, by adopting a thermoelectric element on the outlet of the ice storage, the temperature is increased by the opening of the ice extraction door to compensate for the cold air, which prevents the melting of the ice and prevents the phenomenon of sticking to each other. It is to provide an ice extractor of the improved refrigerator.
