Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow removing device for removing snow from the roof of a house such as a house or a greenhouse.

[0002]

2. Description of the Related Art As a means for removing snow on a roof, an operator climbs on the roof to drop the snow manually, or a snow removal tool driven by a motor or the like is moved to sweep the snow off. Alternatively, measures such as sprinkling water on the roof and sliding off the snow are used.

[0003]

However, when an operator works on the roof, there is a risk of slipping and dropping, and snow is removed by using a snow remover or water sprinkler. In the means, falling snow may be deposited on the gutter and deform the gutter, causing damage.

[0004]

The present invention provides a snow removing device for a house capable of smoothly removing snow accumulated on a roof, and has taken the following technical means. That is, the snow removing device in the house is provided with sliding means for sliding the snow on the sloping roof toward the gutter 1 and snow melting means for melting the snow that has slid near the gutter 1.

[0005]

When the snow on the roof is slid by the sliding means, the snow slides down toward the gutter 1. Then, the snow that has reached near the gutter 1 is melted by the snow melting means. Melting water is gutter 1
Will guide you to a predetermined place.

[0006]

[Effect] Since the snow on the roof is slid by the sliding means, it is safe because the operator does not have to climb the high roof to remove the snow. Then, the snow that has slid off is melted near the gutter 1 and becomes molten water, so that the gutter 1 is not covered with snow and deformation and damage can be prevented.

The greenhouse 9 of the house 2 is provided with a room temperature sensor 45 for detecting the temperature inside the room and an air conditioner 46. Although the air conditioner 46 is configured to supply a steam to adjust the temperature in the embodiment, it may be a heat pump, an air conditioner or the like. It is convenient.

Next, the block circuit of FIG. 7 will be described. Reference numeral 47 is an arithmetic control unit of a microcomputer (hereinafter, referred to as a control unit) having a memory (ROM, RAMU) 48 containing necessary data and control programs. It is called a CPU) and performs operations such as arithmetic / logical and comparison operations. The CP
As information input to the U47 via the input interface 49, information on turning on / off of a main switch provided on the control panel 50, setting water temperature information from a water temperature adjusting switch of hot water sent to the hot water pipes 14, 15, 18 and Water supply pump 27,
Information on / off from the water supply pump switch for driving / stopping 35, 38, water temperature information from the water temperature sensors 28, 36, water level information from the up / down sensors 42, 43, temperature information in the greenhouse from the room temperature sensor 45, etc. is there.

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 temperature of the hot water sent to the hot water pipes 14, 15 and 18 to 80 ° C. and the 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 is jetted upward from the holes 12 and 19. 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. Also, C
Water sent from the third water supply pipe 52 to each side wall pipe 20 by the water supply pump 38 driven by a signal from the PU 47 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, the tip of the snowfall sliding down the adjacent roof 11 comes into contact with each other to form a bridge, but the hot water pipe 14 heated by hot water of about 80 ° C comes into contact with the lower part of the tip of the snowfall to melt. Then, about 20 ° C. is jetted upward from each hole 12 of the snow melting pipe 13.
Water floods the snow to melt the snow and destroy the bridge.

Also, at the left and right ends of the roof 11,
The hot water pipe 18 heated by hot water of about 80 ° C. melts the lower part of the tip of the snowfall that has slid off, and each hole 19 of the snow melting pipe 17 is melted.
The water of about 20 ° C that erupts upward from the water melts on the tip of this snow. The hot water pipes 15 provided on the back surface of the gutter 1 contact the gutter 1 to heat the gutter 1, so that the snow falling on the gutter can be melted.

Therefore, since snow does not accumulate on the roof 11, deformation and damage of the roof 11 can be prevented, and the hot water pipes 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 hot water pipes 14, 15, 18 and the snow melting pipe 1
When the water temperature of the water supplied to 3, 17 may be the water temperature of the water collected in the tank 23, the CPU 47 causes the three-way solenoid valves 2
6, 34, and outputs a switching operation signal to switch. In this case, it is not necessary to operate the water heaters 25 and 33, so that energy can be saved.
