Description

[Detailed Description of the Invention] This invention is a roof snow melting device that forms a plurality of air passages in the roof and uses a blower pump and an intake pump to pass warm air through the air passages to melt lightning on the roof. Roof (There is a method to heat the roof by sending hot water to melt the snow, but there are drawbacks such as hot water leaking and freezing when not in use.
There is also a method of creating a space in the attic or on the roof and injecting the painting style there, but in either case there is no air flow and the heat does not transfer well to the roof, so it can be used especially on bad days, in large quantities, and for long periods of time.
lt Snow (: means that snow cannot be melted. This is because air is a poor conductor of heat and the surface heat transfer rate when it is stationary is poor. How to use it for rivers other than melting snow in winter. This snow melting method and device had major drawbacks in terms of efficiency and economy.

This invention was invented to eliminate the above-mentioned drawbacks, and it can be explained with a drawing that a heat insulating material 2 is placed on top of the roof board l, and above it (both ends leading from the eaves to the ridge) are sealed with a heat insulating frame 9. road 8
A blow pipe 10 having a plurality of blow ports 11 connected to a separate blow pump ■2 and a switching valve etc. is attached to the air passage 8 described in tiiJ, with the blow ports 11 aligned with the air pipe 10. An intake pipe 13 provided with a plurality of intake ports 14 connected to an intake pump 15 and a switching valve is connected to the ventilation path 3.
Intake ITJ14 on the ridge side. Also, connect and wire the snowfall sensor 2 (), hot air generator 16, air blower pump 12, and intake pump 15, install the thermostat 19 in the ventilation passage 8, and connect the hot air generator 16 and air blower pump J2. , intake pump 1
5. It is connected and wired to the heating device 21. A hot air generator 16 and other heat sources (gas stove, water boiler, 70 pots, room residual heat and exhaust heat) can be used on the blower pump 12 side, and a hot air generator 16 is installed on the intake pump 15 side.
And connect piping for use with bubble generators, club rooms, greenhouses, sauna rooms, floor heating mats, heat pumps, and heat exchangers.
The operating method for non-ro equipment is to operate the snowfall sensor 2 (1), the blower pump 12 and the intake pump 15, and the warm air generator 16 to operate the warm air (other heat sources 22 residual heat and exhaust heat). ) inside the ventilation passage 3 (: The air that has transferred heat to the air passage 8 is discharged by the intake pump 15.) If the temperature is +:l, the air is returned to the ventilation passage 8.
It is used by sending it to. Therefore, since the hot air moves through the air passage 3, the surface heat transfer rate of the air increases significantly (as shown in the table below), efficiently heating the air passage 3 and melting snow. Also, by controlling the blower pump 12 and intake pump 15 according to the amount of snowfall and temperature through the action of the thermostat 19 and snowfall sensor 20, the temperature of the ventilation passage 8 can be adjusted by changing the flow of warm air within the ventilation passage 8. . In addition, in order to prevent danger and prevent unnecessary heat release, the thermostat operates at a set temperature, pump 12.15, and hot air generator 1.
This is used to stop and start operation 6.

The use other than snow melting is to use a roof heated by solar heat (the temperature of the air inside the ventilation passage 3 rises from the second side, but this air is taken out by the intake pump 15 and used for multiple purposes.
It can be sent directly into rooms, greenhouses, sauna rooms, floor heating mats, etc. for heating purposes. When the temperature inside the ventilation passage 8 reaches a set temperature, the intake pump 15 is activated by the action of the thermostat 19, and the heating device 2
By connecting to the 1st class, the ventilation passage 8 can be opened while the heating device a is in operation.
If the temperature rise inside the ventilation passage 8 is detected, the intake pump 15 is activated to send warm air into the room and the heating device 21 is stopped.If the temperature inside the air passage 8 is decreased, the intake pump 15 is stopped and the heating device 21 is stopped. is the one that operates. Furthermore, the activation and stopping of this device may be automatic or manual.

Historically, by allowing the air to flow inside the ventilation duct 8, it is also highly effective as an insulating roof.

Therefore, the present invention is a thermally efficient snow melting device that can also be used as a hot air generator, and because it does not use liquid, it is economical and can be used all year round without any liquid leakage or freezing. Roof snow melting device.
