In view of the above problems, as a result of sincerity, the inventor, as a first embodiment, in a building such as an agricultural house or a house, a part of piping connected to a hot water supply facility is supported on the roof of the building. In addition to preventing freezing of residual water in the pipe by attaching a heater to the outer surface of the pipe, water is sprayed by at least a plurality of water holes or sprinklers attached to the pipe supported on the roof. It is a snow melting facility characterized by.

As a second embodiment, in a building such as an agricultural house or a house, a part of a pipe connected to a hot water supply facility is supported so as to be parallel or inclined with respect to the roof ridge of the building, A snow melting facility characterized in that at least a plurality of sprinkling holes or sprinklers attached to a pipe supported by the roof are sprinkled, and a drain outlet is provided for draining residual water in the pipe after the sprinkling is finished. is there.

As a third embodiment, in a building such as an agricultural house or a house, a pipe connected to a hot water supply facility is arranged so as to straddle the roof of the building, and the pipe located on the roof is the building. It is arranged so as to be parallel or inclined to the ridge of the building and is provided with a plurality of sprinkling holes or a sprinkling device, and the pipe connected to the hot water supply facility is provided with a drain outlet for draining the remaining water in the pipe. It is a snow melting facility.

In the first embodiment to the third embodiment, when the pressure discharged from the hot water supply equipment is high, hot water is directly supplied to the roof of an agricultural house or house, and a plurality of sprinkling holes or sprinklers are installed. Snow can be melted by sprinkling hot water from the provided piping toward the roof surface. When the pressure discharged from the hot water supply facility is low, it is necessary to pump hot water with a hot water supply pressurizing pump, and the hot water supply pressurizing pump has a built-in switch that detects hot water from the hot water supply facility and automatically starts and stops the pump. Is preferred. In addition, about the installation place of the said hot water supply equipment, in the case of an agricultural house, you may install in the said house.

In the first embodiment, a heater is wound around the outside of the pipe to prevent freezing in order to prevent the residual water inside the pipe from freezing when the hot water from the hot water supply facility is stopped. As for the heater operation, it is preferable to automatically heat the pipe when the temperature is below the freezing point by the temperature sensor.

In the second embodiment and the third embodiment, since the remaining water in the pipe may freeze while the hot water from the hot water supply facility is stopped, the pipe has a drain outlet. It has a structure that can drain residual water in the piping. Regarding the drainage position, although depending on the pipe arrangement structure, it is preferable to provide the drainage port at least in the vicinity of the pipe connected to the hot water supply facility.

In the third embodiment, when a pipe cannot be directly supported on a building such as an agricultural house or a house, it is a method of standing so as to straddle the roof of the building. If there is a problem in strength, an auxiliary pillar or the like may be used.

In the second embodiment and the third embodiment, even when the remaining water in the pipe is drained, the water sprinkling device and the water sprinkling holes are frozen because some water and water droplets remain. However, it is possible to thaw with hot water supplied into the pipe, but since stable watering is not possible, after draining the remaining water in the pipe, high pressure air is blown into the pipe through the air supply device. The possibility of freezing can be remarkably reduced by flying a small amount of residual water or water droplets in the water sprinkling holes or sprinkling device, and stable operation becomes possible.

Water supply piping valve (V1) connected to the water supply piping (W1) connected to the heat exchanger (41) in the boiler (40) and piping (10) fitted with a heater on the side of the hot water piping and valve for the hot water piping When (V2) is opened, hot water is supplied from the pipe (10) through the heat exchanger, so that water is sprinkled from the sprinkler (20), and the heater of the pipe (10) to which the heater is attached By operating, it is possible to prevent freezing of residual water in the piping. In FIG. 14, when the sprinkler (20) cannot be operated because the pressure on the side of the hot water is weak, water can be sprayed by connecting a hot water supply pressure pump (P) to the pipe.

FIG. 15 is a schematic piping diagram of a snow melting facility when a hot water supply facility already installed in a building such as a house or office is used. A pipe (10) fitted with a hot water heater connected to a heat exchanger (41) in the boiler (40) is branched into a building and a snow melting pipe, and is used as a domestic hot water pipe valve (V3) and water spray. The structure is switched by the piping valve (V2). When the sprinkler (20) cannot be operated because the pressure on the side of the hot water in the watering pipe is weak, watering can be performed by connecting a hot water supply pressure pump (P) to the pipe.

FIG. 16 is a schematic piping diagram of a snow melting facility having a drain outlet. A water supply pipe (W1) connected to the heat exchanger (41) in the boiler (40), a water supply pipe valve (V1) connected to the hot water supply side pipe (15), a watering pipe valve (V2), and a hot water When the pipe valve (V4) is opened, hot water is supplied from the pipe (15) through the heat exchanger, and water is sprinkled from the sprinkler (20). Regarding the drainage of the remaining water in the pipe, drainage can be easily performed by opening the water sprinkling pipe valve (V2) and the drain outlet pipe valve (V5).

After draining the residual water in the pipe (15), the water drop or slight residual water adhering to the inside of the pipe or the sprinkler (20) opens the air supply pipe valve (V6) and the pressure pump (5) By introducing compressed air into the pipe, it is possible to blow off water droplets and operate the snow melting facility stably.

FIG. 18 shows a cross-sectional view of a pipe when a plurality of drain holes are provided in the pipe instead of the sprinkler. Sprinkling with this structure is advantageous in that the device price is low and water can be easily blown by air blowing from the air supply facility.

Regarding the operation of the snow melting facility of the present invention, by setting a timer on the operation panel, for example, watering every predetermined time or installing a snow accumulation sensor on an agricultural house roof or the like, at a stage when the predetermined snow accumulation has occurred. It is preferable to perform control to automatically spray water.

The embodiment of the present invention is an example and can be changed without departing from the present invention. For example, the installation position of the valve for air supply piping (V6) is the valve for watering piping (V2) and the drain piping. It is also possible to connect between the valves (V5). Further, not only buildings such as agricultural houses and houses but also snow accumulated on solar panels can be melted easily by installing the apparatus of the present invention, so that it is possible to improve the reduction in power generation efficiency.
