BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial snowfall device used in various event venues.

[0002]

2. Description of the Related Art In a conventional artificial snowfall device for an event, ice cubes are cut with a rotary blade to form fine ice particles in the shape of a shaved ice, and the ice particles are blown away by an air blower to drop artificial snow.

[0003]

[Problems to be Solved by the Invention] In the conventional snowfall device,
There is the complication that ice cubes for making artificial snow must always be shipped from the ice factory and prepared.

Since the snow quality of artificial snow is sherbet-like because it is cut from ice, it has the drawback of being easily melted, and since it does not fall like actual snow,
The drawback is that it gives a sense of realism for an event.

The present invention has been proposed in order to solve such a problem, and an object thereof is to provide an artificial snowfall device capable of easily producing artificial snow without cutting ice cubes. To do.

[0006]

In order to achieve this object, an artificial snowfall device according to the present invention is installed in a cooling chamber below freezing.
An artificial snowmaking device was installed, and snow was crushed under the artificial snowmaking device.
A conveyor device with a device at the end is provided, and snow is sprayed at one end
The cooling of the air passage that is opened as a mouth and equipped with a blower
It is installed under the chamber, and the conveyor crusher is installed at the bottom of the cooling chamber.
When there is no need for snowfall to drop the snow crushed by the storage into the windway
Is equipped with a drop port that can be closed by a door, and the
A, the crusher, and the blower of the airway are activated
As a structure configured so that the door of the drop port is opened.
It

[0007]

According to the above construction, when the artificial snow accumulated on the belt conveyor is needed, the falling port is opened to drop it on the snow injection device, and the snow injection device blows away the artificial snow to allow snowfall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete embodiment of an artificial snowfall device according to the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment of this artificial snowfall device.

In this figure, a cooling chamber 3 surrounded by a heat insulating wall 2 is installed on a pedestal 1, and the cooling chamber 3 is provided with a cooler 4 provided in this chamber to have a low temperature below freezing (for example, a low temperature). -5 ° C or lower). The low-temperature air produced by the cooler 4 is circulated in the cooling chamber 3 by the cool air circulation fan 5.

In the upper part of the cooling chamber 3, there is provided a breathable snow catcher 6 made of, for example, a synthetic resin cloth material or net material. As shown in FIG. 2, the snow catching body 6 is stretched vertically between upper and lower holding plates 7 and 8, and a snow generating chamber 9 is formed between the snow catching bodies 6. The sub-freezing low-temperature air produced by the cooler 4 is sent into the snow-generating chamber 9 by the circulation fan 5, passes through the snow catcher 6 while rising, and returns to the cooler 4 to be cooled and sent out again. In the figure, the arrow P indicates the flow of low temperature air.

The upper holding plate 7 has nozzles 1 connected to pipes 10a and 10b into which water and pressurized air are sent from the outside.
1 is attached, and fine mist is ejected to the snow generation chamber 9 from this nozzle 11 which constitutes the mist generation device. The mist touches the low temperature air in the snow generating chamber 9 and immediately freezes, forming ice crystals of small particles and adhering to the inner surface of the snow trap 6. In the snow catching body 6, artificial snow grows from the ice crystals, and a snow layer is formed on the inner surface of the snow catching body 6. A snow scraping device 13 is installed on the outer surface of the snow catching body 6 in the width direction of the snow catching body 6 from a rotating brush driven by a motor 12, and the like. By reciprocating up and down while hitting, the snow layer on the inner surface is wiped off. Since
As you can see above, a person with a snow trap, snow generator, and snow scraper
It constitutes a snowmaking device.

The artificial snow that has fallen from the snow catching body 6 is accumulated and stored on a belt conveyor 14 installed below the snow generating chamber 9.

An opening 16 for pressure balancing, which is opened and closed by a damper 15, is provided on the upper portion of the heat insulating wall 2 of the cooling chamber 3.
Is provided.

When it is necessary to snow, the drop port 1 which opens to the lower part (floor part) of the cooling chamber below the exit side of the belt conveyor 14
7 insulating door 17a is opened, and the belt conveyor 14 is driven, artificial snow S on the conveyor 14 is in the snow particle by pulverizing device 18 installed in the outlet portion, the snow particles from falling port 17 of the lower It is dropped on the wind path 19a of the snow injection device 19. Artificial snow that has been dropped in wind trunk 19a is blown off to the outside from the snow injection port 19c by the blower 19b, events
It is rained main snowfall section such as a door venue.

[0015]

[Effects of the Invention] As described above, according to the present invention, it is possible to easily make artificial snow without cutting the ice cubes. To be released.

Further, unlike the artificial snow obtained by cutting the ice cubes, the snow quality is hard to melt and falls like natural snow, so that it is more realistic than before.

Further, since the artificial snow that has been stored can be snowed when necessary, it is possible to perform automatic driving such as starting snowfall together with music at an event site, and the effect of the event can be fully exhibited.
