It is called a CPU) and performs operations such as arithmetic / logical and comparison operations. As information input to the CPU 47 via the input interface 49, information about turning on / off of a main switch provided on the control panel 50 and hot water pipes 14, 15, 18 are provided.
Information on the set water temperature from the water temperature control switch of the hot water sent to the water, on / off information from the water supply pump switch for driving / stopping the water supply pumps 27, 35, 38, and water temperature sensors 28, 36
From the upper and lower sensors 42 and 43, temperature information in the greenhouse from the room temperature sensor 45, and the like.

Further, as a command signal output from the CPU 47 via the output interface 51, the water heaters 25, 3
3 heating amount control signal, water supply pump 27, 35, 38 drive / stop signal, 3-way solenoid valve 26, 34 switching signal, solenoid valve 44 open / close signal, air conditioning device 46 temperature control signal , A display signal to the display tool 53, and the like. Next, the operation will be described.

First, when the main switch of the control panel 50 is turned on, the CPU 47 outputs the output interface 51.
An open signal is output to the solenoid valve 44 via. Then, the water sent from the water source is supplied to the tank 23. When the water level sensor 42 detects the upper limit water level, the CPU 47, which receives this signal via the input interface 49, outputs a solenoid valve close signal via the output interface 51 to close the solenoid valve 44 and supply water. To stop.

When the water temperature adjusting switch of the control panel 50 is operated to set the water temperature of the hot water sent to the hot water pipes 14, 15, 18 to 90 ° C. and the water temperature of the hot water sent to the snow melting pipes 13 and 17 to 20 ° C. The CPU 47 outputs an operation command signal to the water heaters 25 and 33 via the output interface 51, and stops the output of the operation command signal when the water temperature sensors 28 and 36 detect the temperature. When the water temperature sensors 28 and 36 detect that the temperature is lower than the set temperature, CP
U47 outputs the operation command signal to the water heaters 25 and 33 again.

Next, when the water supply pump switch is turned on, the CPU 47 drives the water supply pump 27 via the output interface 51, so that the water in the tank 23 is supplied to the water supply pipe 2.
2, the filter 24, the water heater 25, the three-way electromagnetic valve 26, and the hot water pipes 14, 15, 18 are introduced into the hot water pipes 14, 15 and 18 through the outlets, which are guided to the drain pipe 22a and discharged into the tank 23. Further, the snow-melting pipes 13, 1 pass through the second water-supply pipe 31, the filter-32, the water heater 33, and the three-way solenoid valve 34 by the water supply pump 35 driven by the signal from the CPU 47.
The water in the tank 23 sent to the nozzle 7 blows upward and obliquely upward from the holes 12 and 19 and drops onto the upper part of the roof 6. Then, the water dropped to the gutter 1 is guided to the outlet side, passes through the vertical drain pipe 39 and the horizontal drain pipe 40, and is discharged to the tank 23 by the gutter water guide pipe 41. Further, the third water supply pipe 5 is driven by the water supply pump 38 driven by the signal from the CPU 47.
Water sent from 2 to each side wall pipe 20 is jetted obliquely upward from the hole 21.

When the room temperature sensor 45 is operated to set 20 ° C., the CPU 47 outputs an operation command signal to the air conditioner 46 via the output interface 51 to warm the inside of the greenhouse. When the room temperature sensor 45 detects 20 ° C., the air conditioner 4
When the heating by 6 is stopped and the room temperature sensor 45 detects 20 ° C. or lower, the air conditioner 46 is operated again. When the interior of the greenhouse 9 is heated, the roof 11 warms up and snow on the roof 11 melts the snow that is in contact with the covering 8, so that the snow gradually slides over this covering and moves toward the gutter side. Then, on the gutter, even if the tips of the snow that has slid down the adjacent roof 11 come into contact with each other to form a bridge, the water of about 20 ° C. which is jetted upward from each hole 12 of the snow melting pipe 13 is exposed to the snow. Melt the snow and destroy the bridge. Water flowing down on the covering material or snow that has been destroyed and entered the space A of the gutter 1 is melted in the hot water pipe 14, and the water is temporarily stored in the gutter 1. Then, the water stored in the gutter 1 is heated by the hot water pipe 14 through which hot water of about 90 ° C. flows to become hot water. Therefore, the snow that has fallen subsequently is melted by the warm water.

Also, at the left and right ends of the roof 11,
About 20 sprayed upward from each hole 19 of the snow melting pipe 17.
Melt it by pouring the water at ℃ onto the tip of the snowfall. And, the snowmelt water is a hot water pipe 18 and a gutter 1 through which warm water of about 90 ° C flows.
It is heated by the heating action of the hot water pipes 15 provided on the back surface of the. Since the snow melting pipe 13 and the hot water pipe 14 are arranged vertically, the snow falling speed from the lower end of the clothing material 8 of the roof 6 to the space A of the gutter 1 can be widened, and the snow is easily dropped to enhance the snow melting process. Since the snow is not accumulated on the roof 11, the roof 11 can be prevented from being deformed or damaged. And the hot water pipe 14,
The warm water that has passed through 15 and 18 and the water stored in the gutter 1 can be collected in the tank 23, circulated and reused, so that energy saving can be achieved. Further, when the hot water pipes 14 and 18 come into contact with the water of the gutter 1 or the lower part is soaked, the water temperature of the water in the gutter is increased, so that the energy saving effect is further improved. In addition, the hot water collected in the tank 23 can be reused as the snow melting water ejected from the side wall pipe 20.

The control panel 50 and the water supply pump 35
If you turn on the drive switch of
7 is sprayed upwards and obliquely upwards from the holes 12, 19 to fall on the roof, then flows down, is housed in the gutter 1 and is guided to a predetermined place. Can be washed. In addition, hot water pipe 14,1
If the water temperature of the water supplied to the snow melt pipes 5, 18 and the snow melting pipes 13 and 17 may be the water temperature of the water collected in the tank 23, the CPU 47 outputs a switching operation signal to each of the three-way electromagnetic valves 26 and 34 to switch. In this case, it is not necessary to operate the water heaters 25 and 33, so that energy can be saved.
