Abstract

PROBLEM TO BE SOLVED: To raise the efficiency in carriage of ice blocks and stabilize the discharge of ice blocks. SOLUTION: An ice block sending-out screw 33, which is made by attaching fins 35 for sending out of ice blocks radially in the direction of the peripheral shaft of a rotary shaft 34 are coupled to a drive means, and are arranged inside an ice reserving room to reserve many ice blocks S. The fin 45 is made so that the abutment face 49 directed toward the side of an ice discharge part may inclined to the ice discharge part as it goes outward in radial direction. Hereby for the ice block S, the shifting toward outside in radial direction is regulated when it is carried to the ice discharge part under rotation of the ice block sending-out screw 33, and it never separates from the screw 33.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice block discharging apparatus, and more particularly to an ice block discharging apparatus for efficiently transporting ice blocks stored in an ice storage to an ice discharging section.

[0002]

2. Description of the Related Art For example, in an ice making machine 10 shown in FIG. 8, a lower machine room 14 in which a refrigerating machine such as a compressor 12 and a condenser 13 is housed inside a housing 11 constituting an ice making machine main body.
A box-shaped ice storage 17 which is located above and is surrounded by a heat insulating material 15 and defines an ice storage chamber 16 therein, and an ice making unit 18 disposed above the ice storage 17 basically. It is configured. The ice making unit 18 includes a water tray 19 for storing ice making water at a predetermined level, and an ice making board 21 having ice making projections 20 immersed in the ice making water. The water tray 19 is switched to a deicing operation. The ice making water remaining in the water tray 19 is discharged to the drainage receiving portion 22 and the ice blocks S formed around the ice making projections 20 are discharged to the ice storage chamber 16. ing. The ice storage 17 disposed inside the housing 11 is formed in a box shape that opens upward and forward, and an ice discharge part 24 having an ice discharge opening 23 is opened at the lower front part of the ice storage chamber 16. Further, an ice block discharging device 30 for transporting the ice blocks S toward the ice discharge port 23 is provided at the bottom of the ice storage chamber 16.
Are arranged.

The ice block discharging device 30 is provided with the ice storage 17
A motor (drive means) 31 disposed on the front side of the cover body 25 detachably attached to the front opening of the motor 3;
1 and an ice block delivery screw 33 connected via a speed reducer 32. The ice block delivery screw 3
3 is a cylindrical rotating shaft 34 rotated by the motor 31
And fins 35 spirally attached at a predetermined pitch to the outer periphery of the rotating shaft 34, and extend toward the ice discharge port 23 at the bottom of the ice storage chamber 16.
Therefore, if a large number of ice blocks S discharged from the ice making unit 18 are stored at the bottom of the ice storage chamber 16, the motor 31 is driven and the ice block sending screw 33 is rotated in a predetermined direction. The gap 36 between the fins 35
Are moved sequentially to the ice discharge port 23 side, and then discharged from the ice discharge unit 24 to above the mounting table 26 on the front surface of the ice making machine 10.

[0004]

In the above-described conventional ice block discharging device 30, the spiral fin 35 constituting the ice block delivery screw 33 has a radius from the outer peripheral surface of the rotating shaft 34 as shown in FIG. It extends vertically and linearly outward in the direction. Therefore, even if the ice blocks S properly face the gap 36 between the fins 35, when the ice block sending screw 33 is rotated by the motor 31, the ice blocks S move radially outward while moving toward the ice discharge port 23 side. Before moving to the ice discharge port 23, the fin 35 is separated from the fin 35, and the ice carrying efficiency is reduced. In particular,
The number (amount) of the ice blocks S released at one time is determined by the aforementioned ice block delivery screw 3.
In the case of setting based on the number of rotations of 3, the number (amount) of ice blocks S released from the ice discharge port 23 becomes small, and it is pointed out that the release of the ice blocks S cannot be stabilized.
