Description

[Detailed explanation of the invention] [Purpose of the invention] (Industrial field of application) This invention uses the exhaust heat of indoor heating devices (such as kerosene stoves) to remove snow accumulated on the roofs of houses in snowy regions. This relates to a snow melting device that melts snow by hand.

(Prior art) Various snow melting devices for melting snow on roofs have been researched and developed in snowy regions, and various devices have also been developed that utilize waste heat emitted by indoor heating devices as a heat source for snow melting. .

However, all of these systems have a structure in which the exhaust heat from a kerosene heater, etc. that can be installed indoors is guided to a hot air path installed at the lowest part of the roof, and the snow that has accumulated on the cover plate that closes the top opening of the hot air path is melted. It's getting old.

In other words, the heat from the cover plate heated by exhaust heat is used to melt the snow that accumulates directly on it.
The reality is that with this structure, heat is taken away and the temperature drops, making it impossible to melt snow as desired.

(Problems to be solved by the invention) In view of the above-mentioned circumstances, the present invention eliminates the fact that the cover plate, which is heated by the exhaust heat emitted by the indoor heater, comes into direct contact with the snow and loses heat, and the upper part of the hot air gutter is To be able to always maintain a constant temperature.

[Structure of the idea]

(Means for solving the problems) The means for solving the above problems are:
A hot air gutter is installed at the lowest part of the roof of a house, with a peripheral wall formed of an insulating structure excluding the top surface, and a partition is provided in the center along the length of the hot air gutter to form a U-shaped section in plan. The top opening is covered with a heat storage tank, and a snowmelt water storage tank is provided on one side. A corrugated galvanized iron sheet is laid down on the heat storage tank facing the storage water tank, and air is poured into the top of the corrugated iron sheet. The hole is formed in a conical shape with the hole facing upward, and a hot water pipe is connected to the drain that receives overflow water from the snowmelt water storage tank, and the hot air pipe is introduced into the hot air path, and the exhaust heat from the indoor heater is transferred to the hot air gutter. The gist is a configuration in which an exhaust heat duct is connected and an exhaust pipe is attached.

The exhaust heat supplied to the hot air gutter is the exhaust heat from kerosene heaters used for indoor heating, and the exhaust heat from several heaters used indoors is combined into one supply.

In addition, the roof shape of the house on which the snow melting device of the present invention is installed includes, in addition to the general chevron-shaped roof, a V-shaped roof that slopes downward from both sides toward the center, and a roof that slopes in one direction. Any roof, etc. is fine.

(Function) The snow melting device of the present invention has the above-mentioned configuration.
The exhaust heat from the indoor heater is sent through a heat exhaust duct to the hot air gutter installed at the lowest part of the roof, and the waste heat flows through the gutter, which is divided into a U-shaped plane with a partition, and passes through the top opening of the hot air gutter. Heat is stored by heating a heat storage tank installed to cover the area. The heat stored in the heat storage tank is then blown out through the conical air hole formed at the top of the corrugated galvanized iron sheet placed on top of the tank, and the snow on the corrugated iron sheet is melted by the warm air and the temperature of the corrugated iron sheet itself. However, the snowmelt water flows into the snowmelt water storage tank along the corrugated galvanized iron plate, and the tank is heated by exhaust heat supplied to the hot air gutter. The snowmelt water in the snowmelt water storage tank overflows from the edge of the tank and is introduced into the hot air gutter through a hot water pipe connected to the water drain, so the snowmelt water in the hot water pipe is heated by waste heat and installed separately. The water can be stored in hot water storage tanks or used as water for melting snow on roads, etc.

(Example) Figure 1 shows the snow melting device of this invention installed at the lowest part (eaves) of a mountain-shaped roof, and the snow melting device is attached to the second
As shown in Figures to Figure 4, the cross-sectional shape is rectangular,
Inside the elongated hot air gutter 1 whose three sides except the top are insulated walls, a partition 2 is vertically formed in the center along the longitudinal direction to divide the hot air into a U-shape. A snowmelt water storage tank 4 is mounted on one side of the upper surface of the gutter 1, and a heat storage tank 3 is mounted on the other part.

The heat-insulating structure of the hot-air gutter 1 consists of a frame 1a made of a flat metal plate and filled with a heat-insulating material such as glass fiber or urethane foam in a hollow frame with a U-shaped cross section and an open top, and a heat-insulating structure housed within the frame 1a. The interior is divided into a U-shape in plane by a partition 2 that stands up in the center along the longitudinal direction, and an indoor heater is installed at the base of the U-shaped passage of the hot air gutter 1. An exhaust heat duct 9 for supplying exhaust heat is connected, and an exhaust pipe 10 for exhausting the exhaust heat into the atmosphere is connected to the end of the U-shaped passage.

The heat storage tank 3 is made by wrapping a lightweight beam 3a with mortar 3b made of a mixture of iron sand, sand, and cement.
50mm), and the frame 1a of hot air gutter 1
The periphery of the joint with the frame 1a is sealed with caulking material.

The snowmelt water storage tank 4 is installed and formed on the folded part of the U-shaped passage in the hot air gutter, and the snowmelt water a' flows through a corrugated galvanized iron plate 5 installed on the heat storage tank 3 at an angle toward the snowmelt water storage tank 4 side. In addition to storing
It is heated by exhaust heat supplied to the hot air gutter 1.

A wire mesh 11 is laid on the upper surface of the heat storage tank 3, and a corrugated galvanized iron plate 5 made of a flat metal plate is mounted on the wire mesh 11 so as to be inclined toward the snow melting water storage tank 4 side. A large number of air holes 6 are formed upward in a conical shape, and the snow a on the corrugated iron sheet 5 is removed from the corrugated iron sheet 5.
The snow is effectively melted by its own heat and the warm air blown out from the air holes 6.

The conical shape of the air hole 6 is to prevent snowmelt water a' from entering the lower side of the corrugated iron plate 5 through the air hole 6.

A drainage drain 7 is integrally formed on the outside of the peripheral wall of the snowmelt water storage tank 4, and the boundary peripheral wall with the drainage drain 7 is slightly lowered to receive overflow water from the snowmelt water storage tank 4. A hot water pipe 8 is connected to the drain 7 and introduced into the hot air gutter 1, and is arranged in a U-shape in plan, with the open end of the hot air pipe 8 extending outward from the hot air gutter 1. It can be optionally used, such as protruding from the water and connecting it to a hot water storage tank, or flowing it directly onto the road, or flowing it in the form of a fountain to melt snow on the road. snowmelt water
Since hot water a' is introduced into the hot air gutter 1 through the hot water pipe 8 and heated, it will never freeze even if it is poured onto the road.

In the figure, 12 is a heater such as a kerosene stove that can be installed indoors, 13 is a roof, and 14 is an arm.

Fig. 5 shows a state in which the roof is installed on a house with a V-shaped roof, and since the snow that has accumulated on the left and right slopes is collected in the center and melted, in the case of the chevron-shaped roof of the above-mentioned example, In contrast, in the case of a V-shaped roof, only one device needs to be installed in the center, which is economically advantageous.

[Effect of idea]

As mentioned above, the snow melting device of the present invention has a heat storage tank attached to the top of the hot air gutter that supplies the exhaust heat from the indoor heater, and a corrugated iron plate with conical air holes is laid on the top surface. It has never been reported that heat is taken away by the snow that accumulates on corrugated galvanized iron, so heat is stored in a heat storage tank and maintained at a constant temperature, and hot air is blown out from the air holes in the corrugated galvanized steel to effectively dissipate the snow. It can be melted.

In addition, since the snowmelt water is heated by exhaust heat and then introduced back into the hot air gutter through the hot water supply pipe, the snowmelt water can be used for indoor hot water supply or as snow melting hot water to melt snow on roads.

Furthermore, the heat source for snow melting uses the exhaust heat of a heater such as a kerosene stove that can be installed indoors, which is advantageous from an economic standpoint.
