Abstract

PROBLEM TO BE SOLVED: To permit the enjoyment of a snow play, imaging spring sky, and another snow play through powder snow in one set of indoor sky slope by a method wherein one set of sky slope, formed in a housing, is partitioned into an upper sky slope and a lower sky slope by an air temperature difference but is not partitioned by a partitioning. SOLUTION: Crushed ice 13 is sprayed by a crushed ice ejection nozzle 12 to prepare snow on an upper sky slope 3 while powder snow 14 is fallen from a snow making nozzle 2 to prepare the snow on a lower sky slope 4. Thereafter, an air conditioner 5 for the upper sky slope is operated to maintain the temperature of the space A of the upper sky slop 3 at a plus temperature and another air conditioner 8 for the lower sky slope is operated to maintain the temperature of the space B of the lower sky slope 4 at a minus temperature. The specific gravity of cold air in the lower sky slope 4 is heavier compared with that of warm air in the upper sky slope 3 whereby the air will not be mixed into each other. According to this method, a snow play, imaging a spring sky, and another snow play through powder snow can be enjoyed simultaneously by one set of indoor sky slope.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an indoor snow play facility, and more particularly, to a method in which one slope formed in a building is divided into an upper slope and a lower slope by an air temperature difference without providing a partition. The present invention relates to an indoor snow play facility that can enjoy snow play in the image of spring skiing and snow play by powder snow on two indoor slopes.

[0002]

2. Description of the Related Art In recent years, indoor snow play facilities that allow the user to enjoy snow play, such as skiing, all year round have been constructed and have become very popular.

[0003] The indoor snow play facility has the following configuration. A number of snowmaking nozzles are installed on the ceiling of the building, which is equipped with various facilities such as air conditioning, heat insulation, and lifts, and uniform, fine mist-like water droplets are ejected from each nozzle together with compressed air at a pressure of several atmospheres. You. When the water droplets ejected from each nozzle are ejected at a stretch into the slope space at atmospheric pressure,
The adiabatic expansion deprives the surrounding temperature and lowers it to minus several tens of degrees. In this manner, the rapidly cooled water droplets exchange heat with the cold air in the slope space maintained at a temperature of minus several degrees by the air conditioner while the water droplets scatter from the nozzle by several tens of meters, and gradually freeze to form powder snow. And accumulate on the slopes. Since water droplets are uniformly ejected from the nozzle, uniform snow can be obtained without variation in particle diameter. Hereinafter, the indoor snow play facility described above is referred to as a conventional technology.

[0004]

However, in the above-mentioned prior art, the space inside the building is a single temperature space, that is,
Due to the sub-zero atmosphere, people could play in powder snow, but could not play in the image of spring skiing. On the other hand, on the contrary, the space inside the building, for example,
When the temperature was maintained at about 10 ° C., the snow on the slopes melted, so that it was not possible to play with powder snow.

In order to solve this problem, a slope for snow play in the image of spring skiing and a slope for snow play in powder snow are divided into two by a partition to separate a slope for snow play in the image of spring skiing. May be constituted by crushed ice, and the slope for playing with powder snow may be constituted by the above-described conventional technique. However, in this case, the entire slope is narrowed, and the real pleasure of playing with snow such as skiing is lost.

Accordingly, an object of the present invention is to separate springs formed in a building indoor into upper and lower slopes without providing a partition by an air temperature difference, thereby allowing spring skiing on one indoor slope. It is an object of the present invention to provide an indoor snow play facility where the user can enjoy the imagined play of snow and the play of snow with powder snow, and since there is no partition, a spatial sense of unity can be obtained.

[0007]

According to the first aspect of the present invention,
One slope formed in the building is divided into an upper slope and a lower slope by an air temperature difference, and thus, the upper slope and the lower slope are not separated by a partition. .

[0008] The invention according to claim 2 is characterized in that the space temperature of the upper slope is maintained at a plus temperature, and the space temperature of the lower slope is maintained at a minus temperature.

According to a third aspect of the present invention, the upper slope is made of crushed ice, and the lower slope is made of powder snow.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the indoor snow play facility of the present invention will be described with reference to the drawings. FIG. 1 is a schematic vertical sectional view showing one embodiment of an indoor snow play facility of the present invention.

In FIG. 1, reference numeral 1 denotes a building having an insulated structure of an indoor snow play facility, and 2 denotes a snow-making nozzle of the above-mentioned prior art, which is installed on a lower slope of the building 1 to be described later.
Is the upper slope made of crushed ice, 4 is
The lower slope 5 made of the powder snow of the prior art described above is an upper slope air conditioner for maintaining the space of the upper slope 3 at a plus temperature, for example, about +5 to + 10 ° C., and 6 , The suction duct of the upper slope air conditioner 5, 7 is the upper slope air conditioner 5
It is a spout duct.

Reference numeral 8 denotes a lower slope air conditioner for maintaining the space of the lower slope 4 at a minus temperature, for example, a temperature of about -3 to + 5 ° C., 9 a suction duct of the lower slope air conditioner 8, Reference numeral 10 denotes a discharge duct of the air conditioner 8 for the lower slope, 11 denotes various facilities provided in the building 1, such as galleries, commercial facilities, theme parks, and the like.
Reference numeral 2 denotes a crushed ice jet nozzle provided on the upper slope 3.

Since the present invention is constructed as described above, snow is formed on the upper slope 3 by spraying ice crushing 13 with the ice crushing jet nozzle 12, and the powder snow 14 is dropped from the snow making nozzle 2. The lower slope 4 is made of snow and then the upper slope air conditioner 5
Is operated to maintain the temperature of the space A of the upper slope 3 at a plus temperature, and the air conditioner 8 for the lower slope is operated to maintain the temperature of the space B of the lower slope 4 at a minus temperature.

The warm air on the upper slope 3 maintained at the plus temperature has a lower specific gravity than the cool air on the lower slope 4 maintained at the minus temperature, and therefore stays in the upper part of the building 1. On the other hand, the lower slope 4 maintained at minus temperature
The cold air has a higher specific gravity than the warm air on the upper slope 3 maintained at the plus temperature, and therefore stays in the lower part of the building 1. As a result, the warm air on the upper slope 3 and the cool air on the lower slope 4 do not mix with each other.

Therefore, the upper slope 3 and the lower slope 4
Without providing a partition in the building 1, a snow play in the image of spring skiing can be enjoyed on the upper slope 3, and a snow play with powder snow can be enjoyed on the lower slope 4. That is, it is possible to simultaneously enjoy the snow play with the image of spring skiing and the snow play with powder snow on one indoor slope.
Moreover, since there is no partition on the slope, a sense of unity can be obtained spatially.

When the present invention is applied to the above-described prior art in which the snow making nozzle is provided on the entire ceiling of the building, the snow making nozzle 2 on the upper slope 3 is used for snow making. Just stop the snow.

[0017]

As described above, according to the present invention, one slope formed in a building is divided into an upper slope and a lower slope by an air temperature difference without providing a partition. On one indoor slope, you can enjoy snow play in the image of spring skiing and snow play with powder snow, and since there is no partition on the slope, useful effects such as a sense of spatial unity can be obtained. .
