According to the ice making device of the present invention, the negative pressure forming pipe portion is provided in the middle of the water supply pipe, the air introducing hole is formed in the pipe wall of the negative pressure forming pipe, and the water is supplied to the air introducing hole. A check valve for preventing water leakage is provided, a nozzle part for injecting tap water in the water supply direction is arranged in the negative pressure forming pipe, and the central axes of the nozzle part and the negative pressure forming pipe coincide with each other. Since it was configured like this, the water sprayed from the nozzle,
It is surrounded by the air sucked from the air introduction hole of the negative pressure formation tube and can maintain the speed at the time of jetting and run at high speed inside the head body. At the same time, the suctioned air around the jetted water is entrained. Can be made.

Further, a bent pipe portion is formed in the water supply pipe between the water supply port of the ice making chamber and the nozzle portion, and the inner wall surface of the bent pipe portion is positioned on the extension line of the central axis of the nozzle portion. Since it is configured as described above, it is possible to violently collide the jet water in which the suctioned air around the jet water is caught with the inner wall surface of the bent pipe portion of the water supply pipe. In this way, by speeding up the jet of water jetted from the nozzle, suction of air, and sudden collision of the jetted water, the jetted water is changed into activated water with high vibration that generates high energy, and the water separation pressure is increased. Can therefore be
By making such activated water in an ice making chamber, it is possible to produce ice that has a dense crystal structure and is hard to melt.

1 and 2 show an embodiment of a commercial ice-making device. In the ice making device A, as shown in FIG. It is open to. A water jet generator X is attached in the middle of the water pipe 2, and a solenoid valve V1 for controlling water supply is attached to the water pipe 2 closer to the ice making chamber 1 than the water jet generator X. A main plug V2 is attached near the water pipe. A drain pipe 2a is led out from the lower portion of the ice making device A.

FIG. 2 shows a cross-sectional view of the water jet generating portion X, in which the negative pressure forming pipe portion 3 has the central axes of the water supply pipe 2 and the negative pressure forming pipe portion 3 in the middle of the water supply pipe 2. The negative pressure forming tube 3 has an air introduction hole 4 formed in the tube wall. The air introduction hole 4 is equipped with a check valve 4a for preventing tap water from leaking outside. Inside the negative pressure forming tube 3, a tapered injection port 6a of the nozzle portion 6 is provided.
The central axes of the nozzle portion 6 and the negative pressure forming tube 2 are aligned.

A bent pipe portion 7 is formed at the tip of the water supply pipe 2, and an inner wall surface 7a of the bent pipe portion 7 is arranged on an extension line of the central axis of the nozzle portion 4. It goes without saying that the bending angle θ of the bending tube portion 7 can be appropriately changed in design.

The ice making device constructed as described above is
When the solenoid valve V1 and the main valve V2 are opened, tap water is jetted from the nozzle portion 6 by the tap water pressure to generate a pressure difference in the negative pressure forming pipe 3 as shown in FIG. 2, and this pressure difference communicates with the atmosphere. Air is taken in through the air introduction hole 4. And
The sucked air surrounds the jet water W to prevent the cavitation phenomenon, and the jet water W runs in the water supply pipe 2 while maintaining the speed and shape at the time of jetting.

Further, since the jet port 6a of the nozzle portion 6 is arranged in the negative pressure forming pipe 3 so that the respective central axes thereof coincide with each other, the jet water W runs along the central axis of the water supply pipe 2. The inner peripheral wall 7a of the bending tube portion 7 can be made as it is.
Can be collided with. In this way, the water W
Can be sent to the ice making chamber 1 in an activated state as described in the above-mentioned action section to make hard and non-melting ice.

FIG. 3 shows an embodiment of an ice making device for a large home refrigerator. Water is supplied to the ice making chamber 1 from a water supply tank 8. The water supply tank 8 is set in a refrigerator, and a water supply pipe 2 is provided between the water supply tank 8 and the ice making chamber 1. . In the figure, P indicates a pump for sending the water in the water supply tank 8 to the ice making chamber 1.

In the figure, X indicates a water jet generating portion, which is the first
Since the same structure as that of the embodiment is adopted, the description thereof will be omitted. Further, the bent pipe portion 5 of the water supply pipe 2 is disposed closer to the ice making chamber 1 than the water jet generating unit X.

In the home-use large-scale refrigerator ice making apparatus constructed as described above, the water supply pressure of the pump P is used to generate the water jet W at the water jet generation unit X to control the speed and shape at the time of jetting. By running inside the water supply pipe 2 while holding it and colliding with the inner peripheral wall 5a of the bent pipe portion 5, water is sent to the ice making chamber 1 in an activated state to make hard and non-melting ice.

[0015]

As is clear from the above description, according to the ice making device of the present invention, the speed of the jet water jetted from the nozzle is increased, the air is sucked, and the jet water is suddenly collided, so that the jet water is sprayed. Can be changed to activated water with high vibration that generates high energy, and the separation pressure of water can be made high,
It is possible to produce ice that has a dense crystal structure, is hard and does not melt, and therefore has the advantage that, for example, the drink does not smell like water when placed in a drink.
