Description

[Detailed description of the invention] a. Industrial application field The present invention relates to an ice-making water tank used in an ice-making machine that circulates and supplies ice-making water.
This invention relates to a new improvement for eliminating damage caused by the occurrence of vortices, etc.

b. Prior Art Various configurations have been adopted and proposed for the ice-making water tank in this type of ice-making machine that has been used in the past, but here are some typical configurations: As shown in FIGS. 5 and 6.

That is, in FIG. 5, what is designated by the reference numeral 1 is an ice-making water tank that is box-shaped as a whole and has a wall portion 2 and has a required depth.
An ice discharge hole 4 formed by a bank portion 3 having a height slightly lower than the height of the wall portion 2 of the ice-making water tank 1 is provided approximately in the center of the ice-making water tank 1 .

This ice-making water tank 1 has the above-mentioned bank portion 3.
It is separated into a first water storage part 5 and a second water storage part 6, and these water storage parts 5 and 6 are communicated with each other by a communication water storage part 7, and the wall part 2 on the second water storage part 6 side has a A first suction port 8 and a second suction port 9 are provided.

A deep bottom portion 10 is formed near the wall portion 2 where these suction ports 8 and 9 are provided.

Next, the operation will be explained.

Inside each water storage section 5, 6 and 7 and deep bottom section 10,
As a result of the deicing cycle operation, ice-making water that has fallen from an ice-making plate (not shown) is stored. Next, when the ice-making cycle is started, the ice-making water circulation pumps (not shown) provided at the respective suction ports 8 and 9 of the ice-making water tank 1 simultaneously start suction and suction operations, causing ice to fall from the ice-making plate. The ice-making residual water is returned to the ice-making tank 1, and an ice-making cycle is started by circulating the ice-making water. In this ice-making cycle, the ice-making water returned from the ice-making plate is received in the first water storage section 5 and the second water storage section 6, and the ice-making water received in the first water storage section 5 passes through the communicating water storage section 7 and is then received in the second water storage section 6. Flows into the bottom 10.
Furthermore, the ice-making water received in the second water storage section 6 flows directly to the deep bottom section 10.

Therefore, the flow of ice-making water from the first water storage section 5,
Flows of ice-making water from the second water storage section 6 are combined at the deep bottom section 10 and are sucked through the respective intake ports 8 and 9.

c. Problems to be solved by the invention The above-mentioned operation occurs when the water level of the ice-making water in the ice-making water tank 1 is high. In this case, the required ice-making water is sent to the ice-making plate, so the problem is However, when the water level in the ice-making water tank becomes low, the flow from the first water storage section 5 and the flow from the second water storage section 6 mix almost perpendicularly in the deep bottom section 10, creating a vortex. Furthermore, the flow from the second water storage section 6 caused air bubbling near the first suction port 8 due to the drop section 10a formed at the boundary with the deep bottom section 10. Furthermore, the flow from the first water storage section 5 through the communication water storage section 1a is directed linearly toward the second inlet 9, but the flow from the second water storage section 6 is directed to the first inlet 8.
Since the direction is perpendicular to the suction direction of
The amount of water flowing around the suction port 9 was smaller than the amount drawn by the circulation pump, and the water level near the first suction port 9 was extremely low.

Therefore, when each of the above-mentioned phenomena occurs, the ice-making water that is circulated and supplied to the ice-making plate becomes unstable, containing many bubbles, and the actual amount of circulating water decreases, making it difficult to freeze homogeneously. This resulted in ice-making water circulation pumps running idle and normal ice-making operations becoming impossible.

Also, if the amount of water in the ice making water tank 1 decreases, the above-mentioned problems will occur, so until the ice making is completed,
The amount of water in the ice-making water tank 1 could not be brought to a low level, and the actual amount of ice made relative to the amount of water stored was reduced, resulting in an increase in the amount of water consumed per amount of ice made.
In addition, a large amount of ice-making water remains after being cooled to the freezing point, and when it is diluted and drained with newly supplied ice-making water,
A large amount of cooling energy required for cooling this much ice-making residual water was wasted.

d. Means for solving the problems The purpose of this invention is to provide an extremely suitable means for quickly eliminating the above problems, and this invention has been developed to achieve this purpose. The gist is that the ice-making water is circulated and supplied to the ice-making section, and that the ice-making water that returns from the ice-making section is received. an ice release hole formed by a bank having a required height; a first water storage part and a second water storage part separated by the bank; and a second water storage part provided on a wall on the side of the second water storage part. This is an ice-making water tank in an ice-making machine that includes a first suction port, a second suction port, and a separator having a required height and provided on the second water storage portion side of the bottom portion.

e Effect In the above configuration, the flow of ice-making water from each water storage section is guided by the separator and is guided to each inlet in a parallel flow state without colliding with each other, thereby preventing the generation of eddies and bubbles. It is possible to stably supply ice-making water to the ice-making water circulation pump without the need for ice-making water.

f. Embodiment Hereinafter, a preferred embodiment of the ice-making water tank in the ice-making machine according to the present invention will be described in detail with reference to the drawings.

1 to 3 show an ice-making water tank according to the present invention, and FIG. 4 shows a schematic configuration of an ice-making machine to which the ice-making water tank according to the present invention is applied.

Note that the same or equivalent parts as in the conventional example will be described with the same reference numerals.

In FIG. 1, what is designated by the reference numeral 1 is an ice-making water tank that is box-shaped as a whole with a wall portion 2 and has a required depth. An ice release hole 4 is provided which is formed by a bank 3 having a height slightly lower than the height of the wall 2 of the ice breaker 1 .

This ice-making water tank 1 has the above-mentioned bank portion 3.
It is separated into a first water storage part 5 and a second water storage part 6, and these water storage parts 5 and 6 are communicated with each other by a communication water storage part 7, and the wall part 2 on the second water storage part 6 side has a A first suction port 8 and a second suction port 9 are provided in contact with the bottom surface of a deep bottom portion 10, which will be described later.

A deep bottom portion 10 is formed near the wall portion 2 where these suction ports 8 and 9 are provided. Further, a separator 11 having a height slightly lower than the height of the bank part 3 is formed on the second water storage part 6 side of the bank part 3 and protrudes from the bottom part 1a. It is constructed integrally or separately from the.

Also, the water outlet side of the second water storage section 6 (i.e.
A protruding wall portion 12 protruding in the same height direction as the wall portion 2 and an inclined guide portion 13 formed in a continuous manner with the protruding wall portion 12 are provided at the boundary portion with the deep bottom portion 10 .

The configuration shown in FIG. 4 shows the state in which the ice-making water tank 1 according to the present invention configured as described above is incorporated into a down-flow ice maker, and each inlet 8 and 9
are connected to ice-making water circulation pumps 8b and 9b via suction joints 8a and 9a, and these ice-making water circulation pumps 8b and 9b are connected to the hose 1.
4. It is connected via a pipe 15 and a water supply joint hose 16 to a water sprinkler 20 that sprinkles ice-making water onto each of the ice-making plates 18 and 19 constituting the ice-making section 17.

A case where the ice-making water tank 1 according to the present invention is actually used in the above configuration will be explained.

Inside each water storage section 5, 6 and 7 and deep bottom section 10,
Due to the deicing cycle operation, each ice making plate 18 and 19
Ice-making water that falls from the ground is stored. Next, when the ice-making cycle is started, each ice-making water circulation pump 8b provided at each inlet 8 and 9 of the ice-making water tank 1
and 9b simultaneously start suction and suction operation,
The ice-making residual water that has fallen from the ice-making plates 18 and 19 is returned to the ice-making water tank 1, and an ice-making cycle is started by circulating the ice-making water.

In this ice-making cycle, the ice-making water returned from each ice-making plate 18 and 19 is received by each water storage section 5 and 6, and the ice-making water received at the first water storage section 5 is received by the communicating water storage section regardless of the water level. 1a and the side portion 11a of the separator 11 into the deep bottom portion 10, and then into the second suction port 9 as shown by the arrow.

Furthermore, if the water level flowing down into the second water storage section 6 is higher than the protruding wall section 12, the ice-making water flows directly over the protruding wall section 12 into the deep bottom section 10 and flows over the inclined guide section 13. A portion of the ice-making water that has passed is changed direction at the side portion 11b of the separator 11, guided into the deep bottom portion 10, and then guided to the first suction port 8.

Furthermore, the water level in the ice-making water tank 1 is lower than that of the protruding wall 1.
2, the flow of ice-making water in the second water storage section 6 is blocked by the protruding wall section 12, flows down the inclined guide section 13 as shown by the arrow, and flows down the separator 1.
The flow is changed by contacting the side 11b of the first
It joins the flow of ice-making water from the water storage section 5 in a parallel state, and is sent into the ice-making water circulation pumps 8b and 9b from the first suction port 8 and the second suction port 9, respectively.

Therefore, when the water level in the ice-making water tank 1 becomes low, the ice-making water from the second water storage section 6 passes through the inclined guide section 13 and is redirected by the separator 11 to flow from the first water storage section 5. Because they are parallel,
The generation of vortices and bubbles is completely prevented.

It should be noted that the above-mentioned embodiment is an example, and it goes without saying that the same effects can be obtained even if slight changes are made to the configuration of each part.

Further, in this embodiment, the bank part and the separator are integrated, but the same effect can be obtained even if they are made separately and a slight distance is provided between them and the bank part.

As a result of experiments, it was confirmed that a configuration in which the protruding position of the separator 11 is located at the boundary between the protruding wall portion 12 and the inclined guide portion 13 is the most suitable for guiding water.

g Effects of the invention Since the ice-making water tank in the ice-making machine according to the invention has the structure and function described above, each water stream is drawn in parallel at each suction port, and
The generation of eddies and bubbles can be reliably suppressed, and ice-making water is supplied to each ice-making water circulation pump in an extremely stable state. Therefore, a constant amount of ice-making water can be circulated and ice-making can be carried out stably without causing the pump to idle or insufficient water supply due to insufficient water volume, and without reducing drive efficiency.

In addition, since the ice making water can be circulated more stably up to the lower water level than in conventional tanks, it is possible to make ice until the ice making water runs out, reducing the amount of ice made in one ice making cycle. This increases the efficiency of using the stored ice making water, and it is possible to reduce the amount of water consumed relative to the amount of ice made.

Furthermore, the ice-making residual water that remains in the tank when ice-making is completed has a temperature close to the freezing point, but when this ice-making residual water is diluted and drained to supply water for the next ice-making cycle, this ice-making residual water is If the ice-making water is too large, most of the energy used to cool the ice-making water will be wasted, but with the ice-making water tank of the present invention, the ice-making water can be extremely reduced, making it more effective. It is possible to achieve significant energy savings.
