Description

【0001】
【発明の属する技術分野】
本発明は、製氷機から貯氷庫内に溜めた砕氷などの細かい氷を解砕して確実に排出するようにした製氷装置に関する。
【0002】
【従来の技術】
従来、製氷装置の一例として図8及び図9に示すものがある。これは、一辺の長さが10〜15mm程度の細かい氷、即ち砕氷gを製造する製氷機1と、該製氷機1から排出した砕氷gを貯留する横長箱状ホッパー形貯氷庫2と、該貯氷庫2の底部に設けた略U字状トラフ3内に落とし込んだ砕氷gをそのトラフ3の端部側排出口4に向かって矢印a方向に搬送して貯氷庫2外に排出するためのスクリューコンベア5とを備え、前記貯氷庫2内に解砕手段6が設けられている。
【0003】
前記解砕手段6は、貯氷庫2内の中央部に水平方向に沿って回転駆動可能に配置した互いに平行する2本の軸体7aと、該各軸体7aの外周面に放射状に突設した多数のクラッシャバー7bとを備えた一対のクラッシャ7からなり、該各クラッシャ7を駆動モータ8により互いに逆向き方向bに回転させて、貯氷庫2内で氷結した砕氷gを解砕する。
【0004】
上記構成では、両クラッシャ7を互いに逆向き方向bに回転させて砕氷gを解砕させるようになっており、これでは、各クラッシャ7のクラッシャバー7bが短いため、両クラッシャ7とスクリューコンベア5との間で砕氷gがブリッジ状に氷結成長して氷塊底層G1が形成されたり、貯氷庫2の内側面に沿って砕氷gが氷結成長して氷塊壁層G2が形成されると共に、貯氷庫2の開口部2aに沿って砕氷gが氷結成長して氷塊天井層G3が形成されることがあり、これにより、各クラッシャ7及びスクリューコンベア5の周囲に空隙Sが形成されて、貯氷庫2内から砕氷gを排出することができなくなるおそれがある。
【0005】
上記問題点を解消するため、本発明者が特許文献1に記載の技術を開発した。これは、図8に仮想線で示すように、スクリューコンベア5の羽根部5aを所定ピッチで螺旋巻きした軸体5bに、同一ピッチの羽根部5cを部分的に追加して、その両羽根部5a,5cにより短いリードLaと長いリードLbとを交互に形成したものであって、その両羽根部5a,5cの短いリードLaの部分で持ち上げた砕氷gを両クラッシャ7で解砕することにより、砕氷gの氷結によるブリッジの形成を阻止するものである。

[Prior art]
FIG. 8 and FIG. 9 show an example of a conventional ice making device. An ice maker 1 for producing fine ice having a side length of about 10 to 15 mm, that is, ice crushed g, a horizontally long box-shaped hopper type ice storage 2 for storing ice crushed g discharged from the ice maker 1, The crushed ice g dropped into the substantially U-shaped trough 3 provided at the bottom of the ice storage 2 is transported in the direction of the arrow a toward the end side discharge port 4 of the trough 3 to be discharged out of the ice storage 2. A screw conveyor 5 is provided, and crushing means 6 is provided in the ice storage 2.
[0003]
The crushing means 6 includes two parallel shafts 7a arranged at the center of the ice storage 2 so as to be rotatable along the horizontal direction, and radially protrudes from the outer peripheral surface of each of the shafts 7a. A plurality of crusher bars 7b each having a plurality of crusher bars 7b. Each of the crushers 7 is rotated by the drive motor 8 in the opposite direction b to break the crushed ice g frozen in the ice storage 2.
[0004]
In the above configuration, both crushers 7 are rotated in opposite directions b to break the crushed ice g. In this case, since the crusher bar 7b of each crusher 7 is short, both crushers 7 and the screw conveyor 5 are crushed. The crushed ice g freezes and grows in a bridge-like manner to form an ice block bottom layer G1, or the crushed ice g freezes and grows along the inner side surface of the ice storage 2 to form an ice block wall layer G2. In some cases, the crushed ice g freezes and grows along the opening 2a of the second ice block 2 to form an ice block ceiling layer G3, whereby a gap S is formed around each crusher 7 and the screw conveyor 5, and the ice storage 2 There is a possibility that the crushed ice g cannot be discharged from the inside.
[0005]
In order to solve the above problems, the present inventor has developed a technique described in Patent Document 1. This is achieved by partially adding blades 5c of the same pitch to a shaft body 5b in which the blades 5a of the screw conveyor 5 are spirally wound at a predetermined pitch, as indicated by phantom lines in FIG. Short leads La and long leads Lb are alternately formed by 5a and 5c, and the crushed ice g lifted by the short leads La of the blades 5a and 5c is broken by both crushers 7. To prevent the formation of bridges due to freezing of the crushed ice g.

The formation of the ice block wall layer G2 (see FIG. 9) along the inner side surface of the ice storage 2 can be prevented.
[0024]
Further, the tip of each of the stirring rods 11 is also brought close to the screw conveyor 5 in the trough 3, and the crushed ice g is reliably crushed by the screw conveyor 5 and the tip of each of the stirring rods 11 approached thereto. As a result, the ice block bottom layer G1 (see FIG. 9) is not formed between the two 5 and 11, unlike the conventional case, and the crushed ice g is reliably dropped into the trough 3 from the horizontally long box-shaped ice storage 2. be able to.
[0025]
Further, the tip of each of the stirring rods 11 is brought close to the opening 2a of the ice storage 2 so that the crushed ice g to be frozen into the opening 2a of the ice storage 2 is dropped off by the tip of each stirring rod 11. Therefore, it is possible to reliably prevent the ice block ceiling layer G3 (see FIG. 9) from being formed in the opening 2a as in the related art.
[0026]
In addition, a crushing claw 12 is fixed to the tip of each of the stirring rods 11 so as to be orthogonal to each of the stirring rods 11, and the crushing claws 12 will adhere to the inner peripheral surface of the ice storage 2. Crushed ice g can be reliably scraped off.
[0027]
FIGS. 3 and 4 show an ice making apparatus according to a second embodiment of the present invention, in which a crushing means 6 is vertically arranged at a central portion in an ice storage 2 formed in a vertically long rectangular tube shape. A shaft 10 rotatably disposed along the shaft 10 and a plurality of stirring rods 11 protruding near the upper and lower ends of the shaft 10, and a crushing claw 12 fixed to the tip of each stirring rod 11. A downward crushing rod 14 approaching the inner peripheral surface of the ice storage 2 and approaching the screw conveyor 5 in the trough 3 is protrudingly provided on the lower stirring rod 11, and an opening of the ice storage 2 is provided on the upper stirring rod 11. An upward crushing rod 15 approaching 2a protrudes. A bearing member 16 rotatably supports the shaft body 10. The configuration other than the above is substantially the same as that of the first embodiment shown in FIGS.
[0028]
According to the above configuration, it is possible to prevent the ice block wall layer G2 (see FIG. 9) from being formed along the inner surface of the ice storage 2 as in the first embodiment. 5 and the downward crushing rod 14 approached thereto, the crushed ice g is reliably crushed, so that an ice block bottom layer G1 (see FIG. 9) is not formed between the crushed ice 5 and the crushed ice 14 as in the prior art. In addition, since the crushed ice g to be frozen in the opening 2a of the ice storage 2 is dropped off by the upward crushing rod 15, the ice block ceiling layer G3 (see FIG. 9) is formed in the opening 2a as in the related art. Can be reliably prevented.
[0029]
In the above-described second embodiment, the ice storage 2 has a vertically long rectangular cylindrical shape. However, the present invention is not limited to this. The ice storage 2 has a vertically long cylindrical shape as shown in FIG. You may. In this case, since the crushing claws 12 are close to each other over the entire inner peripheral surface of the ice storage 2, the crushed ice g to be attached to the inner peripheral surface can be more reliably scraped off (third embodiment). Form).
[0030]
【The invention's effect】
According to the first aspect of the present invention, the ice stored in the ice storage by the plurality of stirring rods protruding from the shaft by rotating the shaft disposed in the center of the ice storage. , The ice in the ice storage can be crushed so as not to freeze, and the tip of each stirring rod is brought close to the inner peripheral surface of the ice storage. The formation of an ice block wall layer along the inner surface of the body can be prevented.
[0031]
According to the second aspect of the present invention, the ice is reliably crushed by the screw conveyor and the tip of each of the stirring rods approaching the screw conveyor, so that an ice block bottom layer is formed between the two as conventionally. Therefore, fine ice such as crushed ice can be reliably dropped into the trough 3 from the horizontally long box-shaped ice storage.
[0032]
According to the third aspect of the present invention, since the ice to be frozen in the opening of the ice storage is dropped off by the tip of each stirring rod, an ice block ceiling layer is formed in the opening as in the related art. Can be reliably prevented.
[0033]
According to the invention as set forth in claim 4, since the ice is reliably crushed by the screw conveyor and the downward crushing rod approaching the screw conveyor, an ice block bottom layer can be formed between the two as in the related art. As a result, fine ice such as crushed ice can be reliably dropped into the trough from the vertically cylindrical ice storage.
[0034]
According to the fifth aspect of the present invention, the ice to be frozen in the opening of the ice storage is dropped by the upward crushing rod, so that the ice block ceiling layer is formed in the opening as in the related art. It can be reliably prevented.
[0035]
According to the invention as set forth in claim 6, the crushing claw fixed to the tip of each stirring rod can reliably scrape off the ice that is going to adhere to the inner peripheral surface of the ice storage.
