BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial snowfall device for an environment test room for a snow resistance test of a vehicle or a snow experience dome.

[0002]

2. Description of the Related Art A conventional artificial snowfall device is installed directly in a place where it is intended to be used, for example, in an environment test room for vehicle-related snow resistance tests such as automobiles, or in a snowfall experience dome (experience room).

In such a conventional artificial snowfall device, it was not possible to store snow during non-testing in the test room or closing the experience dome.

Therefore, the artificial snowfall device is stopped during non-testing and closed, and the artificial snowfall device is preliminarily operated before the start of the test or before the opening of the building to generate artificial snow, but it takes time to prepare. was there.

[0005]

[Problems to be Solved by the Invention] The present invention separates the artificial snow production room from the environmental test room and the experience dome for the purpose of use, and the artificial snowfall room also serves as a storage room, and the environmental test room and the experience dome are artificial. When snow is needed, the snow accumulated in the snow production room is transported to the environmental test room and the experience dome by a conveyor so that artificial snowfall can be reproduced immediately. The snow can be transported to the place, and it is not necessary to install an artificial snowfall device for each intended place, so the facility cost can be reduced.

[0006]

In order to achieve the above object, an artificial snowfall device of the present invention is provided with an artificial snowmaking device in a snow producing chamber, and descends from the device under the artificial snowmaking device. Conveyor receiving snow and snow on the conveyor
The 貯雪cooler for cooling the provided also between the snow generation chamber and the object using room, provided screw conveyor you transport the snow from the conveyor to the target using chamber, the screw con
In addition to the bare air pipe, one end of which is open at the bottom of the snow production chamber
It has a structure with connected ends .

[0007]

[Action] The artificial snow falling from the artificial snow making device in the snow producing chamber is accumulated on the belt conveyor in the lower part of the indoor.

The snow on the belt conveyor is supplied to the next screw conveyor, and the supplied snow is conveyed into the use chamber by the screw conveyor and falls into the use chamber.

[0009] The screw conveyor is supplied via an air pipe
Since it is cooled by the cooling air from the snow storage cooler , the screw conveyor is at the same level as the lower part of the snow production chamber.
Kept in cold, snow in the conveyor is conveyed smoothly without or solidified melt Ketari.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to a specific example shown in the accompanying drawings.

In FIG. 1, reference numeral 1 is an artificial snow producing chamber in which an artificial snow manufacturing device 2 is provided, and the artificial snow manufacturing device 2 has, for example, the following structure.

That is, a large number of vertical cooling plates 3 made of hollow bodies are arranged in parallel at appropriate intervals.
A cooling medium, for example, brine, is sent from the forward pipe 4a to the pipe, and brine in the plate is returned from the return pipe 4b to a brine cooling device (not shown), where it is cooled and fed again from the forward pipe 4a into the plate 3. I try to circulate.

A humidifier 5, a cooler 6 for cooling the room, and a blower 7 are provided in the snow producing chamber, and the moisture in the high-humidity air containing steam from the humidifier 5 is the surface of the cooling plate 3. It freezes and becomes frost.

On the surface of each cooling plate 3, there is provided a scraper 8 composed of a brush or the like for scraping off frozen frost. The scraper 8 is reciprocally moved up and down on the surface of the cooling plate. The frost on the cooling plate surface is evenly scraped off, and the scraped frost falls into artificial snow-like artificial snow 9.

An endless belt conveyor 10 is provided in the lower part of the snow producing chamber, and artificial snow falls on this conveyor.

Further, in the snow producing chamber, there is a first screw conveyor 1 having a screw 11b in a vertical pipe 11a.
1 is provided in the lower part of the conveyor 11 so that snow falling from one end of the belt conveyor is supplied from a chute 13 by a scraper 12, and the snow is rotated by a motor M1 to rotate a screw 11b. And is raised in the first screw conveyor 11.

The scraper is driven by a motor (not shown).

On the upper part of the first screw conveyor 11,
Horizontal second with screw 14b in pipe 14a
One end of the screw conveyor 14 is connected, and the outlet of the other end of the conveyor 14 is the intended use room such as the test room 1.
5, the shutter 16 is provided at the exit, and the snow that is moved in the second screw conveyor by the drive of the motor M2 drops into the test chamber by opening the shutter 16.

If necessary, a snow stocker 17 is provided in the test room, a test object such as a car or a snow boat 18 is carried under the stocker 17, and a shutter (not shown) at the bottom of the stocker is opened to open the stocker. Let the snow fall on the test object.

In the second screw conveyor, the air cooled by the snow storage cooler 22 in the lower part of the snow producing chamber is supplied from the air blower pipe 20 by the blower 19.

In FIG. 1, reference numeral 21 is a partition made of a mesh or the like, and 23 is a blower.

[0022] Figure 2 is first, second shows an example in which the outer cylinder 24, 25 to each screw conveyor,貯雪for a cold from vent 26 into the outer cylinder 24 of the first screw conveyor
The cooling air from the cooling device 22 flows in and out to cool the first screw conveyor, and the cooling air from the snow storage cooling device 22 is also blown into the outer cylinder 25 of the second screw conveyor from the air blower pipe 20 by the blower 19. is, the second screw conveyor is cooled, whereby the first, snow in the second screw conveyor fusion Ketari, are to prevent or hangs.

[0023]

According to the present invention, the artificial snow dropped by the snow making device is temporarily stored on the conveyor in the snow producing chamber, and the accumulated snow is conveyed to the intended use chamber by the screw conveyor for the intended use. You can drop artificial snow into the room at any time.

Further, since the first and second conveyors for carrying snow from the snow producing room to the intended use room are screw conveyors, it is possible to carry all the snow without spilling.

[0025] Moreover screw conveyor because it is cooled by the cooling air from the generating chamber bottom of 貯雪cooler 22, rather than snow may like solidify fusion Ketari in,
It can carry snow smoothly.
