Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ice block feeding device that can appropriately supply desired ice blocks using an ice block transfer member such as a screw.

An example of a conventional ice block feeding device is explained with reference to FIG. 1. A is a hopper for storing ice blocks, and has a drop opening at the lower end, and this drop opening is connected to an extraction port d communicating with an ice block supply port C of the main body. The passage e is connected to a screw f for transferring ice blocks from a drop opening to a take-out opening d.
was set up.

With this configuration, only one ice block enters the screw f from the drop port, so there is a risk that an uneven amount of ice blocks will be delivered to the takeout port d. In order to prevent ice blocks from flowing directly into the outlet d, the dimensional relationship between the transfer passage e and the screw f should be made strict, or measures should be taken to make the transfer passage e sloped so that the outlet d side is located upward. Various design specifications needed to be taken into consideration, such as the need to take measures against cold air leaks and outside air inflow.

The present invention was developed to solve these drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 indicates the ice making machine main body, and the inside of the main body 1 is divided into an ice making section A, an ice block supply section B, and a machine room section C from above.

The ice-making section A includes an ice-making plate 2 that generates sheet ice, a circulation pump 3 that circulates ice-making water through the ice-making plate 2, a water sprinkler 4, a water storage tank 5, and ice blocks that are small enough to convert the sheet ice into ice cubes. A cutter grid 6 and the like for cutting are appropriately arranged.

The machine room B houses a compressor 7, a condenser 8, a blower 9 for cooling the condenser 8, and the like, which together with the evaporator 2' of the ice-making plate 2 constitute a refrigeration cycle.

Next, the ice block supply section H will be explained.

The supply section B has a supply chamber 11 closed by a door 10 at the lower front thereof, and this supply chamber 11 has an ice block outlet 1.
2, and is equipped with an operation switch (not shown) for operating an ice block transfer device, which will be described later.

Reference numeral 13 denotes a hopper for storing the ice blocks cut by the cutter grid 8, and has an ice block falling port 14 at its lower end.

The ice block outlet 12 and the ice block falling port 14 are located apart from each other, and are communicated with each other by an ice block transfer passage 15 arranged horizontally.

Reference numeral 16 indicates the ice block in the transfer passage 15 through the drop port 14 and the take-out port 1.
This is a transfer device for transferring to the transfer passage 15, which has a drive motor 17 driven by the operation of an operation switch, one end of which is fixed to the rotating shaft 18 of the drive motor 17, and the other end parallel to the transfer passage 15, which is connected to the opposite motor of the passage. It consists of a screw shaft 19 supported on the side and a helical screw 20 fixed to this shaft 19.

This screw 20 is located directly below the drop port 14 and extends from the rear end of the drop port 14 at the inner side 1 of the front end.

That is, it has a width T' that is slightly smaller than the width T of the drop opening 14.

Reference numeral 21 denotes an elastic partition member that hangs down from the front end of the screw 20, and is made of a soft material such as rubber.

That is, the transfer passage 15 is divided by the partition member 21 into a portion 15a where the screw 20 is located and where the ice blocks are moved by rotation of the screw 20, and a portion 15a where the ice blocks are moved after passing through the partition member 21 and are transferred to the extraction port 12 by being pushed together. 15b.

This partition member 21 connects the upper end mounting portion 21a to the transfer passage 15.
At the same time, since the screw shaft 19 is inserted through the center, an angular insertion hole 21b that is sufficiently larger than the shaft diameter and a cutout 21c that hangs down from the insertion hole 21b at the lower end 1 are formed. ing.

Next, the ice block retrieval operation in the above configuration will be explained.

When the user operates the operation switch, the motor 17 rotates and the screw 20 also rotates.

Therefore, a large number of ice blocks in the hopper 13 are placed on the screw 20 below the ice block falling port 14, and are transferred to the transfer path by rotation.
5 is pressed toward the portion 15b from the portion 15a.

The ice block pressed by the screw 20 passes through the partition member 21
It passes through and accumulates on the portion 15b side.

At this time, the lower end side of the partition member 21 is bent toward the portion 15b due to the elasticity of the partition member 21, and the shaft 19 and the insertion hole 21b are bent.
However, since the hole 21b is square, there is little resistance.

In addition, since ice blocks are sent out sequentially from the slit 21c, even if the amount of ice blocks that enter the screw 20 varies, a fixed amount is delivered by the slit 21c, and
2, the ice block itself is sequentially sent out by the amount of movement.

Furthermore, the ice block falls from the cutter grid 8 and falls into the fall port 1.
4, the partition member 21 prevents cold air from flowing to the outlet 12, and at the same time prevents cold air from leaking.

As is clear from the above description, the ice block feeding device according to the present invention stores ice blocks and transfers ice blocks by connecting a hopper having an ice block dropping port at the lower end and an ice block dropping port and an ice block taking out port almost horizontally. a passage; a screw disposed only at a position facing the ice block falling port in the ice block transfer passageway to transfer the ice blocks from the falling port to the take-out port; and a transfer tip of the screw that partitions the fall port and the take-out port. and an elastic partition member, this partition member is provided substantially vertically within the transfer passage, and an insertion hole for the shaft of the screw and a cut at a lower end of the insertion hole are formed from a part of the insertion hole. Ice blocks are not caught between the inner wall of the transfer passage and the screw, ice blocks are not thrown out from the drop port to the take-out port, and there is no leakage of cold air.

Furthermore, since there is no need to incline the transfer passage or to lengthen the screw, the design is easy and it can be manufactured at low cost.

Further, the partition member has an upper end fixed at a proper position in the transfer passage, and has an insertion hole for a screw shaft that rotates the screw.By forming a slit at the lower end 1 from a part of the insertion hole, ice blocks can enter the screw. Even if the material is old roses, the amount that passes through the cut is constant, making it possible to supply a fixed amount.
