Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water production device capable of producing core-heated water (water that is entirely transparent) by continuing stirring by introducing air throughout ice production.

[Background of the invention and description of prior art]

It is widely known that raw water for ice making is placed in a freezing can and placed in a water line to produce water, but the freezing conditions often change between the periphery and the center of the freezing can. In addition, the water in the center and the periphery were often in different states, and for this reason water was often created with a core.

Until now, in order to make ice without a core, that is, completely transparent, an air supply stirring tube was inserted into the center of the freezing can, and the ice making process was carried out while air was pumped in and stirred. An attempt was made to do this, but with this method,
When the ice-making raw water in the freezing can progresses to become near the center, it is necessary to take out the air-feeding and stirring tube in order to avoid the air-feeding and stirring tube from being fixed due to freezing. In other words, the wick gradually becomes smaller and the tube for air supply and stirring is removed at an appropriate point to prevent it from sticking to the water surface. , resulting in water that is not transparent in the center, that is, water with a core. Therefore, an attempt was made to stir the ice-making raw water until the end of the ice-making process, and by doing so, it was possible to make water that was completely transparent. In order to prevent freezing, the air supply stirring tube must be manually removed gradually as the freezing progresses.

The inventors of the present invention have repeatedly conducted research with the intention of developing a device that can automatically take out the tube for air supply and stirring according to the progress of ice formation during ice-making operations, without manual intervention. We have arrived at the present invention.

[Object of the invention and summary of the invention]

An object of the present invention is to automatically continue stirring raw water by introducing air throughout the ice making process without relying on human hands, thereby producing water without a core (water that is entirely transparent). The goal is to provide equipment.

The present invention is a coreless water ice-making device characterized by comprising a freezing can, an air-feeding stirring tube, and an automatic lifting and lowering mechanism for the air-feeding and stirring tube.

[Detailed description of the invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The coreless water ice making apparatus of the present invention will be specifically explained with reference to the drawings.

■ is a freezing can, 2 is a compressed air reservoir (not shown) or a compressor (not shown) via a flexible ice cube 3
20 is the lid of the freezing can 1, on which the automatic lifting mechanism of the drop tube 2 is mounted. 4 and 5 are guide rollers of the drop tube, 6 are guide rollers 4 and 5
and 7 is a lift roller of the drop tube 2, the shaft 14 of which is interlocked with the deceleration motor 8,
The lift roller 7 is rotated in the direction of the arrow at a very slow speed of 10 rotations per minute by the deceleration motor 8, and when it comes into contact with the drop tube 2, it slowly raises the drop tube 2. 9 is a guide rail 10
12 is a support base for the lift roller 7 and the deceleration motor 8, and 13 is a spring, which moves the slide plate 9 on which the lift roller 7 and the deceleration motor 8 are placed onto the guide rail 10. and 11 towards the support rod 6 on which the guide rollers 4 and 5 are attached, thereby pulling the drop tube Z
is sandwiched between the guide rollers 4 and 5 and the lift roller 7, and the rotation of the lift roller 7 pulls the drop tube 2 upward.

14 is the axis of the lift roller, 15 is a guide pin attached to a position close to the circumference of the lift roller 7, and 16 is a guide pin attached to a position near the circumference of the lift roller 7.
is a backing plate fixed to the lid 20, and the lift roller 7
When the guide pin 15 rotates in the direction of the arrow, the guide pin 15
6, and by the rotation of the lift roller 7, the slide plate 9 on which the lift roller 7 and the deceleration motor 8 are placed,
While stretching the spring 13, it moves from the support rod 6 in the direction in which it is heated. As a result of this movement, the lift roller 7 is detached from the drop tube 2, as shown in FIGS. 3 and 5, and the drop tube 2 falls into the freezing can 1 due to its own weight. When the pin 15 reaches a position past the upper end of the backing plate 16, the slide plate 9 on which the lift roller 7 and the deceleration motor 8 are mounted is drawn to the support rod 6 by the spring 13, whereby the lift roller 7 is dropped. abuts tube 2 again, thereby causing drop tube 2
is sandwiched between guide rollers 4 and 5 and lift roller 7,
Then, as the lift roller 7 rotates, it rises again.

In the ice making apparatus of the present invention, an air motor that uses compressed air may be used as the deceleration motor 8 that is the prime mover for the rotational force of the lift roller 7.

Further, it is preferable that the drop tube 2 is made of a light material so that the total amount of electricity is not very heavy.

This is because, in the freezing can 1, ice grows from the peripheral wall and the bottom thereof, so that the falling of the drop tube 2 does not destroy the frozen layer at the bottom.

An example of producing coreless water using the ice making apparatus of the present invention will be described.

Fill the freezing can 1 with raw water for the manufacturing process, submerge the freezing can 1 into the cooling brine tank so that the top surface is not immersed, cover the lid 20 with the drop tube 2 and its automatic lifting mechanism, and immediately pour compressed air into the drop tube. 2 into the freezing can 1 to start air agitation of the ice-making raw water, and at the same time, start the deceleration motor 8 and rotate the lift roller 7.

As the lift roller 7 rotates, the drop tube 2 that comes into contact with it slowly rises, but when the guide pin 5 of the lift roller rough comes into contact with the backing plate 16, the lift roller 7 separates from the support rod 6 together with the slide plate 9.
The lift roller 7 is thereby removed from the drop tube 2. At this time, the drop tube 2 falls to the bottom of the freezing can 1, and as shown in FIG. 3, its tip lands on the bottom and stops, but the guide pin 15 of the lift roller 7
6, the slide plate 9 on which the lift roller 7 and deceleration motor 8 are placed is drawn toward the support rod 6 by the spring 13, the lift roller 7 comes into contact with the drop tube 2, and the drop tube 7 is pulled up by the rotation of In this way, the drop tube 2 feeds compressed air into the ice making raw water in the freezing can 1 and repeats rising and falling while constantly stirring.

Even if a layer of ice is formed at the bottom of the ice can 1, the drop tube 2 stops falling on the top surface of the layer of ice, as shown in FIG. Since the rotation is performed at a predetermined length depending on the rotation, the drop tube 2 is pulled upward by the amount of growth of the frozen layer. For this purpose, the drop tube 2 can feed compressed air into the freezing can 1 and continue stirring the ice making raw water until the ice making raw water in the ice freezing can 1 is completely frozen. Transparent water with no white water or opaque parts can be created, but this rising and falling of the drop tube 2 is caused by the constant rotation of the lift drawlough and the contact plate of the guide pin 15 of the lift roller 7. This can be done automatically by movement due to contact and separation.

〔Effect of the invention〕

When using the ice-making apparatus of the present invention, it is possible to make water that is completely transparent and without a core or prismatic water using ordinary ice-making means without requiring any manual labor.
