【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、例えば屋根等に用いられる融雪装置に係る
ものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a snow melting apparatus used for a roof or the like, for example.
従来、降雪地方における除雪作業は大変な作業であ
り、特に屋根の雪降ろし作業には危険も伴うものであ
る。その解決策としては、屋根に熱線、あるいはヒート
パイプ等を配設して雪をとかしていく方法、または機械
的に雪をかき降ろす方法がある。2. Description of the Related Art Conventionally, snow removal work in a snowfall area has been a difficult work, and particularly, snow removal work on a roof involves danger. As a solution, there is a method of arranging a heating wire or a heat pipe on the roof to melt snow, or a method of mechanically shaking snow.
しかしながら、機械的な方法では装置が大掛かりとな
ってしまうと共に、屋根の意匠性、デザイン性の自由度

あった。However, there are drawbacks that the mechanical method requires a large-scale device and reduces the degree of freedom in design and design of the roof. In the case where a hot wire is used, there is a disadvantage that the running cost is increased. Furthermore, when a heat pipe is used, heat is taken away due to snow melting while the heat medium is moving in the heat pipe, and the heat medium supply side and the heat medium return side of a heat medium supply device such as a boiler are used. There was a drawback that the degree of snow melting was different and the snow remained.

することを可能とした融雪装置を提案するものである。In order to eliminate such disadvantages, the present invention circulates a heat medium made of liquid and connects a heat medium supply side and a heat medium return side to a heat medium supply device side of a hollow pipe disposed in the entire area of the snow melting part. Two bypass pipes are arranged, and one of the two bypass pipes is connected to a hollow pipe on the side of the snow melting part on the heat medium supply side and on the heat medium supply device side on the heat medium return side from the other one. Connected, and in the middle of each of the two bypass pipes,
Opening / closing valves are provided between the connecting portions of the hollow pipe and the two bypass pipes. By opening and closing the four opening / closing valves, the movement of the heat medium in the snow melting part is changed, and the heat medium in the hollow pipe is removed. The present invention proposes a snow melting apparatus which makes it possible to make the degree of snow melting caused by heat radiation substantially constant.

こととなる。Hereinafter, a snow melting apparatus according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic explanatory view showing a typical example of the snow melting device, and 1 is a heat medium supply device, which includes, for example, a boiler using gas, kerosene, electricity, a heat source such as a heat pump, a motor, and a pump. The heat medium returned from the snow melting unit 3 is heated and supplied to the snow melting unit 3 again. Numeral 2 denotes a hollow pipe for moving a heat medium made of a liquid over the entire area of the snow melting section 3, and the snow melting section 3 radiates heat of the heat medium in the hollow pipe 2 to melt snow. The hollow pipe 2 is, for example, a copper pipe, a pipe made of a general steel material, which has been subjected to rust prevention treatment, or a synthetic resin pipe, and the cross-sectional shape is arbitrary such as a circle, a triangle, and a square. Of course, it is also possible to combine different materials such as a copper pipe only for the snow melting part 3 and a PVC pipe for the others. The snow melting part 3 is a part that melts snow by releasing heat of a heat medium on the ground such as a roof or an entrance. Reference numeral 4 denotes a first bypass pipe having an opening / closing valve 6 in the middle, and a heat medium supply side of the hollow pipe 2.
2a and the heat medium return side 2b. Reference numeral 5 denotes a second bypass pipe, which has an on-off valve 7 in the middle.
More specifically, the second bypass pipe 5 is connected to the hollow pipe 2 closer to the snow melting portion 3 than the first bypass pipe 4 on the heat medium supply side 2a, and is connected to the heat medium supply device from the first bypass pipe 4 on the heat medium return side 2b. It is connected to the hollow pipe 2 at one side,
The first bypass pipe 4 and the second bypass pipe 5 cross each other. Reference numerals 8 and 9 denote on-off valves. On the heat medium supply side 2a, the on-off valve 8 is connected to the hollow pipe 2 between the connecting portions 4a and 5a between the first and second bypass pipes 4 and 5 and the hollow pipe 2. On the side 2b, an opening / closing valve 9 is provided between connecting portions 4b and 5b between the hollow pipe 2 and the first and second bypass pipes 4 and 5. These four on-off valves 6 to 9 are preferably operated in conjunction with each other. This opening / closing operation changes the moving direction of the heat medium in the snow-melting part 3 and increases the length of the hollow pipe 2 in the snow-melting part 3. Even so, snow melting can be performed reliably. The opening and closing valves 6 to 9 are
For example, it is a manual type, an electromagnetic type, and an electric type. The heat medium is, for example, a liquid such as an antifreeze. In addition, when the opening and closing valves 6 and 7 are closed and the opening and closing valves 8 and 9 are opened, the heat medium flows from the heat medium supply device 1 through the hollow pipe 2 and flows through the snow melting part 3 in the direction of the arrow α.
The circulation path returns to the heat medium supply device 1 again. When the opening and closing valves 6 and 7 are opened and the opening and closing valves 8 and 9 are closed, the heat medium supplied from the heat medium supply device 1 passes through the first bypass pipe 4, and the direction of the arrow β in the snow melting part 3. Flows to
The circulation path returns to the heat medium supply device 1 via the second bypass pipe 5. By performing the opening and closing of the opening and closing valves 6 to 9 by using a timer, a sensor, or the like, the snow melting at the positions A and B in the snow melting section 3 can be performed in the same amount.

Further, the snow melting device can be installed in the same manner as a conventional heat pipe. In addition, when used for a roof, since the hollow pipe is provided, the shape and design of the roof can be freely designed. There are effects and features such as.
