Description

ICE STORAGE DEVICE OF ICE MAKERS

The present invention relates to an ice storage device for an ice maker, and to an ice storage device for an ice maker in which an ice exit is formed at an upper portion of an ice storage and a coil-type guide member is implemented.

Auger type ice maker consists of an auger consisting of an auger (spiral blade) coupled to the auger shaft of the ice maker, a cylindrical inner cylinder member (also called an ice making cylinder) surrounding the auger, and a guide rib. A compressed section of auger shaft comprising a compression passage between the inner cylinder member and the organal, and a pressure head for dewatering and simultaneously removing moisture from the compression section; and an ice storage chamber ( bingo) is made.

The ice storage (also referred to as ice storage) is a hard ice pillar from which moisture has been removed by being compressed, and is stored in the ice storage chamber as standardized chip-like ice by contacting the inclined surface of the pressing head. The chipped ice stored in the ice storage should be maintained in chip shape for the quality of the ice until it is discharged for drinking.

However, in conventionally known ice storages, some of the stored ice melts and decreases in size due to inaccurate cooling management, and ice lumps adhere to the bottom of the ice storage. Agitating blades made of rods are formed to prevent static ice from sticking by rotational contact, but there are disadvantages in that the shape of ice is damaged or the melting of ice is accelerated by the stirring blades.

In addition, when manufacturing a compact ice maker with a small size, there was a problem in that it was difficult to manufacture a small ice maker due to the reasons such as the arrangement space occupied by the ice bin and the high installation height of the bin It also became a problem in that the melted water from the stored ice was discharged from the bottom of the storage to the ice exit.

The rotation 30 of the guide is the whole by the rotation shaft 33 that fixes the base end 32 while the guide pin 221 supports the center of the guide pin 221 in the pin hole (symbol omitted) of the front end 31 . By rotating the guide member 30 in the clockwise direction, the ice on the mounting surface 34 is loaded from the bottom to the top and ascended.

In addition, although the guide member 30 forms a coil shape, a fine jaw (not shown) can be further formed so that the angle of the mounting surface does not fall into the storage body 21 in a state where ice is mounted. Therefore, it is possible to increase the rate of ascent of the loaded ice.

Of course, some ice may fall to the center of the guide member 30 when the ice rises, but most of the ice rises and exits to the ice exit 211 .

On the other hand, the conical dispersion member 60 can be installed in the middle between the bottom part 213 and the guide member 30 so as to push the ice falling to the middle of the falling ice of the bottom part 213 toward the inner peripheral wall 212 side. have. By installing such a conical dispersing member 60, the ice accumulated in the middle of the storage body 21 is dispersed toward the inner peripheral wall 212 side, so that the stored ice can rise and exit through the coil-shaped guide member 30 immediately after supply of the stored ice. It is possible to prevent the long waiting of ice.

Most of the raised ice comes out from the inside of the ice exit 211, but the ice mounted on the distal end 31 and the mounting surface 34 of the guide member 30 rotating in the clockwise direction does not stop rotating again. It can be stopped at the member 40 to make ice exit through the ice exit 211 .

In particular, the ice exit 211 can widen the opening amount of the ice exit 211 by lowering the height of the ice exit 211 by the forward and reverse driving of the second driving motor 218, thereby increasing the amount of ice. Also, by raising the block member 216 , the opening amount of the ice exit 211 can be reduced, thereby reducing the amount of ice exiting.

Of course, ice made through a separate ice maker is supplied as needed through the ice supply unit 223, and when full ice is detected by an ice full sensor (not shown), the supply can be stopped, and the rotation of the guide member 30 can also be changed by the user. Ice skating can be stopped by switching of
