Abstract

PURPOSE:To artificially form snow that flies flutteringly. CONSTITUTION:A method of artificially forming snow is constructed such that a cooling structure 3 cooled to a temperature of the freezing point or lower is rotated, and thin ice pieces are formed by dropping water droplets on the cooling structure 3, and further the ice pieces shaken off from the cooling structure with centrifugal force are blown off by fan means 5. The method is further constructed such that a fluorescent paint added to the water droplets and the ice pieces blown off by the fan means 5 are irradiated with black light. Hereby, there is ensured snow which persons look at and enjoy.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial snow generating method, and more particularly to an artificial fluttering snow generating method.

[0002]

2. Description of the Related Art As a method of generating artificial snow indoors or outdoors, a method of ejecting mist-like water droplets and compressed air from a snow-making gun into the atmosphere below freezing and freezing the water droplets in the atmosphere to cause snow accumulation. There is a method in which lumpy ice is crushed into powdery ice, which is blown into the atmosphere by a blower to cause snow accumulation.

[0003]

However, the above-mentioned conventional method for generating artificial snow is intended for accumulating snow, and the particle size of the artificial snow generated is large and the flight time is extremely short. Therefore, it is not something that you can enjoy watching the falling snow.

An object of the present invention is to provide an artificial snow generating method which is different from the above-mentioned conventional artificial snow generating method and which allows the user to enjoy watching the snow falling as it flutters. I am trying.

[0005]

The artificial snow generating method according to the present invention rotates a cooling body cooled to a temperature below the freezing point, drops water droplets on the cooling body to form thin ice pieces, and applies centrifugal force. The ice pieces that have been shaken off by the cooling body are blown off by the blowing means.

In addition, a fluorescent paint is added to the water droplets, and the ice pieces blown off by the blowing means are irradiated with black light.

[0007]

The water droplets dropped on the cooling body are instantly frozen into thin ice pieces because the cooling body is cooled to a temperature below the freezing point. Then, the generated ice pieces are shaken off from the disk by the centrifugal force generated by the rotation of the cooling body.

When the ice pieces thus generated are blown off by a blowing means, the ice pieces look like fluttering snow, so by continuously making such ice pieces, You can enjoy watching it fluttering.

Further, if a fluorescent paint is added to water drops and a black light shines on the fluttering ice pieces in the dark, the ice pieces fluoresce, so that a fantastic snowfall state can be brought about.

[0010]

EXAMPLE An artificial snow generating method according to an example of the present invention will be described with reference to FIG. By flowing a refrigerant inside it, below zero 2
The disk 3 cooled to about 0 ° C. is rotated, and the water droplet 2 is dropped from the water container 1 on it. As a result, the water droplets 2 are rapidly deprived of heat by the disk 3 to be iced, and instantly become thin ice pieces 4.

Then, the ice pieces 4 thus generated are shaken off from the disk 3 by the centrifugal force generated by the rotation of the disk 3 and tend to fall by its own weight. If the ice pieces 4 in this state are blown away by the fan 5, it is possible to form a fluttering snow scene over a wide range.

Further, a fluorescent paint is added to the water drop 1,
When the black light irradiator 6 irradiates the ice pieces 4 blown off by the fan 5 with the black light, fluorescence is emitted from the ice pieces 4, so that a more fantastic snowfall state of fluttering snow can be enjoyed.

It should be noted that the snowfall state changes depending on the temperature of the atmosphere in which the ice pieces 4 fall, and if the atmosphere temperature is above the freezing point, the ice pieces 4 are likely to melt in the middle and become a slushy state.
If the ambient temperature is below the freezing point, the ice pieces 4 will fall directly to the surface of the earth.

In the present embodiment, the disk having the vertical rotation axis is used, but the direction in which the ice pieces fly can be changed by inclining the rotation axis.

Further, if the cylinder is laid sideways and rotated about the longitudinal axis, the ice pieces can be projected with a width in the same direction.

[0016]

EFFECTS OF THE INVENTION Fluttering snow can be generated by a simple device, and by emitting snow,
It is possible to improve the fantastic effect.
