In this case, the bottom of the ice storage tank 1 is inclined so that it becomes lower toward the ice making section 1a, and the ice making section 1a
Refrigerant reservoir 1 which is much lower than the bottom at the lowest point of
c is formed.

An antifreeze liquid (hereinafter referred to as a refrigerant) having a specific gravity larger than that of water and being insoluble and having a freezing point below freezing is stored in the refrigerant storage portion 1c. Further, the ice making section 1a is formed with a cylindrical ice making chamber 1b which is isolated from the refrigerant storage section 1c with its opening side facing. The bottom surface of the ice making section 1a facing the opening of the ice making chamber 1b is inclined downward toward the refrigerant storage section 1c, and the refrigerant is stored on the inclined surface of the refrigerant storage section 1a.
A straightening vane (not shown) for pouring into c is provided.

On the other hand, the refrigerant reservoir 1c and the upper portion of the ice making chamber 1b are connected by a refrigerant circulation pipe 3 which constitutes a circulation system. A refrigerant circulation pump 4 and a refrigerator 5 are provided on the refrigerant reservoir 1c side of the refrigerant circulation pipe 3, and a refrigerant ejection nozzle 6 is provided at a refrigerant outlet provided at an end portion connected to the ice making chamber 1b to form a heat medium circulation system.

Sherbet-like ice is stored in the upper portion of the ice storage tank 1, and water is stored in the lower portion thereof. The water is stored by a circulating water pump (not shown) connected to an outlet near the bottom of the ice storage tank 1. Water is circulated in the ice making chamber 1b through the circulating water supply port 7 provided in the upper portion of the ice making chamber 1b. In this case, the water taken from the upper part of the ice storage tank 1 is heated by the heating boiler 8 and merges with the water discharged from the lower part of the ice storage tank 1.

In the ice heat storage device having such a structure, in the first example, a foamed polystyrene is provided at the interface of the refrigerant storage section 1c in order to prevent the formation of an ice block (hereinafter referred to as anchor ice) which hinders the operation of the device. It floats a lot of solid material measuring about 10 cm square made of wood and synthetic resin.

Further, in the third example, the heating portion 10 such as a heating wire is provided near the interface between the refrigerant and the water in the refrigerant reservoir 1c. Next, the operation of the ice heat storage device configured as described above will be described.

The refrigerant cooled to 0 ° C. or lower by the refrigerator 5 is discharged from the refrigerant slurries 6 in the ice making chamber 1b to the ice making chamber 1b.
Blow out inside. On the other hand, in the upper part of the ice making chamber 1b, the water extracted and sent by the water circulation pump from the water intake port is supplied through the water discharge port, and when the cold refrigerant blows out from the refrigerant jet nozzle 6, the water and the refrigerant falling downward are generated. They come into direct contact with each other, and the temperature of the water decreases due to heat exchange between the water and the refrigerant, and ice pieces are generated there.

Both the ice pieces and the refrigerant are contained in the ice making chamber 1b.
From the lower opening to the bottom of the ice making section 1a, the ice pieces rise in the water from the bottom due to buoyancy and are guided into the ice storage tank 1, and in the process, the refrigerant separated from the ice pieces goes to a straightening plate (not shown). It flows along to the refrigerant storage part 1c and is stored.

After this, the refrigerant is extracted from the refrigerant reservoir 1c by the refrigerant circulation pump 4, sent to the refrigerator 5, cooled again to 0 ° C. or lower, and the above-described circulation is repeated.
By the way, during such an ice manufacturing process, anchor ice may be generated at the refrigerant interface, which may interfere with the ice making operation.

However, as in the first example, the refrigerant reservoir 1c
By suspending the solid matter at the refrigerant interface, it is possible to prevent the generation of large ice blocks. Further, as in the second example, cooling water having a high temperature that has exchanged heat with the refrigerant is injected into the interface between the refrigerant and the water stored in the refrigerant storage portion 1c, so that the vicinity of the interface is heated and a large ice block is prevented from occurring. it can.

As described above, according to the first example, by suspending the solid matter at the refrigerant interface where there is a risk of anchor ice generation to prevent anchor ice generation, the ice making operation can be continued without interruption. can do.

Further, according to the second example, the vicinity of the interface is heated by injecting the cooling water having a high temperature that has exchanged heat with the refrigerant into the interface between the refrigerant and the water stored in the refrigerant storage section 1c. This has the effect of preventing the formation of large ice blocks and allowing smooth operation of the refrigerator.

Further, according to the third example, the refrigerant reservoir 1
The heating section 10 such as a heating wire is provided on the wall surface near the interface between the refrigerant and water of c and the stagnation part in the refrigerant storage part 1c to heat the interface near the interface between the refrigerant and water and the stagnation part of the refrigerant, thereby storing the ice storage tank. Since the formation of anchor ice that hinders the circulation of the refrigerant is prevented, the operation of the device can be continued.

FIG. 2 shows a second embodiment of the ice heat storage device according to the present invention. The same parts as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. Only the different points will be described here. .

In the second embodiment, as shown in FIG. 2, the refrigerant discharged from the refrigerant circulation pump 4 is connected between the input side of the refrigerator 5 and the upper portion of the ice making chamber 1b to prevent freezing. The piping 12 leads to a freezing prevention nozzle provided separately from the refrigerant ejection nozzle 6 at the refrigerant outlet in the upper part of the ice making chamber, and the freezing prevention refrigerant piping 12 is provided with a control valve 13. In addition, the temperature of the refrigerant reservoir 1c is detected by the thermometer 14 and the detection signal is input to the controller 15, and the controller 15 calculates the temperature at which no ice block forms in the refrigerant reservoir 1c,
The flow rate of the refrigerant flowing through the antifreezing refrigerant pipe 12 is adjusted.

In the ice heat storage device having such a structure, the refrigerant for jetting ice 6 and the refrigerant having a relatively high temperature flow out from the refrigerant jet nozzle 6. That is, as the anti-freezing refrigerant, the refrigerant taken out from the ice storage tank 1 passes through the circulation pump 4, and then passes through the anti-freezing refrigerant pipe 12 branched on the inflow side of the refrigerator 5 to prevent the freezing of the upper portion of the ice storage chamber 1b. Directly to the nozzle for use.

At this time, the control valve 13 is opened according to the temperature value calculated by the controller 15 on the basis of the refrigerant temperature of the refrigerant reservoir 1c detected by the thermometer 14 so that no ice lumps are formed in the refrigerant reservoir 1c. The degree is controlled.

Therefore, the temperature of the refrigerant ejected from the medium ejecting nozzle 6 is kept optimum by the refrigerant having a high temperature ejected from the freeze prevention nozzle at any time, so that the icing of the tip of the nozzle can be prevented.

As described above, in the second embodiment, the flow rate of the refrigerant for freeze prevention is adjusted to control the temperature of the refrigerant jetted from the refrigerant jet nozzle 6, so that the icing of the tip of the nozzle is prevented. , Can prevent the formation of anchor ice.

FIG. 3 shows an example of the structure of the refrigerant ejection nozzle in the third embodiment of the ice heat storage device according to the present invention. In the conventional refrigerant jet nozzle 6, since the tips of the nozzle outer cylinder 6a and the inner cylinder 6b, which are coaxially arranged, are on the same plane, icing may occur at the nozzle tips.

Therefore, in the third embodiment, as shown in FIG.
As shown in (a), the refrigerant ejection nozzle 6 has a structure in which the tip of the inner cylinder 6b is retracted more inward than the tip of the outer cylinder 6a.

With the refrigerant ejection nozzle 6 having such a shape, the refrigerant ejected from the loose tip 16 causes a contracted flow as shown in FIG. 3 (b). That is, the conventional refrigerant ejection nozzle is
Although the inner diameter of the cylinder of the nozzle and the diameter of the liquid column of the ejected refrigerant are almost equal, when the refrigerant ejection nozzle 6 of FIG. 3 (a) is used, the diameter of the liquid column is the inner diameter of the cylinder of the nozzle as shown in FIG. 3 (b). It becomes smaller than that and causes contraction.

Therefore, it is known that the refrigerant having a contracted flow has a great effect as an antifreezing refrigerant and is unlikely to cause ice accretion at the nozzle tip. It can prevent the occurrence.

FIG. 4 shows a constitutional example of a fourth embodiment of the ice heat storage device according to the present invention. The same parts as those in FIG. 2 are designated by the same reference numerals and the description thereof will be omitted. Will be described only.

In the fourth embodiment, as shown in FIG. 4, an agitator 17 is provided in the refrigerant reservoir 1c, and the agitator 17 is provided.
Is directly connected to the electric motor 18 provided in the lower portion of the refrigerant reservoir 1c to stir the refrigerant in the refrigerant reservoir 1c.

Therefore, with such a configuration, the refrigerant in the refrigerant reservoir 1c is constantly stirred, so that the refrigerant reservoir 1
Large ice blocks are no longer generated in c,
You can continue making ice for a long time.

FIG. 5 shows a first configuration example of the current plate in the fifth embodiment of the ice heat storage device according to the present invention. In the ice heat storage device shown in FIG. 1, the refrigerant that has passed through the ice making chamber 1b flows over a straightening plate (not shown) provided on the inclined bottom surface of the ice making part 1a and flows into the ice making part 1a. This type of conventional straightening vane uses a flat plate, but with this flat plate straightening plate, the falling speed of the mixture of water and refrigerant is smaller than that in the ice-making chamber, so when the cooled water becomes ice, a large amount of ice Easy to form pieces.

In the first example of the straightening vanes in the fifth embodiment, a water-repellent corrugated straightening vane 18 is formed as shown in FIG. It is the one.

By using the straightening vane 19 having such a configuration, water does not coalesce with each other on the straightening vane, and large ice blocks are not generated in the ice storage tank 1. Further, since the water-repellent material is used for the straightening vanes 19, the water lumps do not coalesce on the straightening vanes.

Therefore, since a large ice block does not occur in the ice storage tank 1, it is possible to prevent the formation of anchor ice which hinders the operation of the apparatus. 6 and 7 show second and third configuration examples of the straightening vanes in the fifth embodiment of the ice heat storage device according to the present invention.

In the second configuration example of the straightening vanes in the fifth embodiment, as shown in FIG. 6, a large number of strip-shaped plates 20 are arranged side by side to form a straightening vane 21, and each strip-shaped plate is provided on both sides thereof. It is rotatably supported by a support plate 22 provided in the section. A rectifying plate adjusting device 23 is provided on the lower surface of the rectifying plate 21.
Is provided.

The current plate adjusting device 23 is formed by arranging slender balloon-shaped bags so that air can be taken in and out when necessary. With the straightening vane 21 having such a configuration, it becomes a single plate shape as shown in FIG. 6 when the air is removed, and as shown in FIG. 7 when the straightening plate adjusting device 23 is filled with air. Since each balloon-shaped bag swells, the current plate 21 bends in a stepwise manner.

Therefore, by periodically letting air in and out of the straightening vane adjusting device 23, the straightening vane 21 is alternately changed into a flat plate shape and a staircase shape, so that the growth of ice formed on the straightening vane 21 can be prevented. It will be possible.
