DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow melting apparatus in a multi-zone type greenhouse in which a greenhouse assembled on a gable or ridge type roof is constructed by arranging the ridges in parallel in multiple directions. About improvement.

[0002]

2. Description of the Related Art As shown in FIG. 1, a continuous greenhouse A is a unit greenhouse 1 assembled on a gable roof, or
As shown in FIG. 2, unit greenhouses 1 to be assembled on a ridge-type roof are arranged in a row in a row with the directions of the ridges 10 aligned. And the eaves of the roof 12 inclined to the left and right of the adjacent unit greenhouses 1... Are connected by the valley 2 supported on the upper end of the support 11.

[0003] This multi-unit type greenhouse A has the advantage that the construction cost can be reduced and the site area for constructing the greenhouse can be efficiently used. However, in the snowy region, the greenhouse A is accumulated in the valley 2. We need a way to melt the falling snow and run it away.

Conventionally, as shown in FIG. 1, the snow melting means provided in this multi-unit type greenhouse A is provided with a water sprinkling device 3 at the top of each ridge 10 of the unit greenhouses 1. From here, water that maintains a stable water temperature, such as well water, is sprayed little by little to melt the snow or, as shown in FIG. 3, hot air is blown to the ceiling of the interior of each unit greenhouse 1. Arrange the hot air duct 4 ...
By slightly opening the skylight 13 of the roof 12 of each unit greenhouse 1, the roof 12 is blown out along the outer surface of the roof 12, or the hot air blown out of the hot air duct 4 is used to cover the roof 12, By indirectly raising the temperature of the multilayer plate, the snow on the upper surface of the roof is melted and flows down from the valley gutter 2.

[0005]

SUMMARY OF THE INVENTION The above-mentioned connected greenhouse A
The snow melting means provided in the former is a means for spraying water by providing the water spraying device 3 on the top of the former building 10, and when the outside air temperature falls to a temperature lower than about minus 5 degrees C, water spraying is performed. As the melted snow becomes a sharppet and loses its fluidity and solidifies, a large amount of this sharppet-like snow accumulates near the valley gutter 2, increasing the load weight and causing the greenhouse A to collapse. There is a problem that the water sprinkling pipe of the water sprinkling device 3 is piped outdoors, and is often damaged by freezing.

When the valley gutter 2 is heated by a heating means such as a hot water pipe, it is desirable to dispose the heating means inside the greenhouse from the viewpoint of thermal efficiency. It is difficult to provide a temperature raising means for raising the temperature of the gutter due to the structure of the greenhouse.

The means for arranging the hot air duct 4 in the upper part of the room of the unit greenhouse 1 heats the covering material of the roof 12 and the multilayer plate with the hot air blown out of the hot air duct 4 in the room. ,
When the indirect method of melting the snow on the roof 12 with the heat is used, the thermal efficiency is poor, and when the synthetic resin material such as vinyl chloride with high heat insulation is used for the covering material of the roof 12 and the multilayer board. However, there is a problem that the thermal efficiency is further deteriorated.

Also, due to these problems, the greenhouses are not constructed in a row structure, but are independently provided for each unit greenhouse, and are often spaced apart from adjacent unit greenhouses by sliding snow on the roof. Although there is also a means for constructing the apparatus in parallel with a series, this method has a problem that the utilization efficiency of the site is poor and the material cost of the unit greenhouse increases, thereby increasing the equipment cost.

[0009]

An object of the present invention is to solve the above-mentioned problems occurring in the conventional means, and to construct a greenhouse in a continuous-building type while arranging multiple greenhouses on each roof of unit greenhouses in parallel. It is an object of the present invention to provide a new means for efficiently melting and falling snowfall.

[0010]

According to the present invention, as a means for achieving the above-mentioned object, a unit greenhouse 1 having a roof 12 inclined left and right is made parallel to the ridge 10, and In a multi-span greenhouse A in which the columns 11 on the adjacent side are shared and arranged side by side in multiples, the valley gutter 2 connecting the eave ends of the roofs 12 of the unit greenhouses 1.1 arranged in parallel is formed in a channel shape by a metal material. And left and right side walls 2
1 and 21 are connected to the eaves end of the roof 12, and the upper ends of the columns 11 project above the eaves end of the lattice beam 140. And a space surrounded by the outer surfaces of the side walls 21 and 21, the lower surface of the covering material 12 a of the roof 12, and the upper surface of the lattice beam 140. w is formed in a greenhouse, and a heating means 5 composed of a hot water pipe or the like is disposed in the space w, and the heating means 5 is applied to an outer surface of the side wall 21 of the valley gutter 2 on the indoor side. The present invention proposes a snow melting device in a connected greenhouse.

[0011]

According to the present invention, a snow melting apparatus in a multi-span greenhouse according to the present invention has a trough connecting the eaves of the roofs of the unit greenhouses arranged in parallel with each other in a channel shape made of a metal material having good heat conductivity. In addition, a space w surrounded by the outer surface of the side wall, the lower surface of the covering material of the roof, and the upper surface of the lattice beam is formed on the inside of the room on the outer surface side of the side wall. Since the temperature raising means is always in contact with the outer surface of the side wall of the valley gutter, the efficiency of the entire valley gutter is improved by the temperature raising means provided in the room of the greenhouse. The well-heated snow that is in contact with the inner surface of the valley is melted and slides down toward the bottom wall of the valley, and is further melted by the rising bottom wall to form running water. It is discharged from the part to the outside through the downspout.

[0012]

Next, an embodiment will be described in detail with reference to the drawings. In the drawings, the same reference numerals are used for components having the same effects as those of the conventional means.
