Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a roof snow melting device.

[Prior Art] Various such devices are provided. One of these days,
Electric snow melting equipment has a planar heating element installed on the roof.
Snow melts using electric heat, but electricity costs are high. Hot air snow melting equipment installs piping that blows hot air onto the roof and uses the heat of the warm air to melt snow, but its snow melting efficiency is low. Hot water snow melting equipment circulates hot water through pipes or mats installed on the roof and uses the heat of the hot water to melt snow, but those using pipes have low snow melting efficiency, and those using mats have high equipment costs. A heat pipe type snow melting device has a unit panel of heat pipes installed on the roof surface, heats the working fluid in the pipe with hot water from the boiler, and melts snow using the heat of vaporization generated by this, but the equipment cost is high.

Furthermore, since all of the above four types of devices have their heat generating parts fixed to the roof surface, they deteriorate over time due to sunlight and outside air, resulting in reduced durability.

In addition, a hollow sheet-like material is installed on the roof,
Japanese Utility Model Application Publication No. 168729/1983 discloses a technique for providing a heated gas and sending the heated gas, that is, hot air, into the hollow interior of the hollow space. However, in such known technology, if the roof is large and the partitions are enlarged, the sheet material partially swells due to the weight of snow.
The passage of heating gas is restricted, reducing snow melting efficiency.
Alternatively, the amount of heating gas is not adjusted properly.

[Problem to be solved by the invention] Therefore, the purpose of the invention is to provide a roof snow melting device that can efficiently melt snow over the entire roof surface and can be easily removed when not in use during the summer. be.

[Means for Solving the Problems] According to the present invention, in a roof snow melting device for melting snow on a roof, a rigid resin sheet made of an epidermis and a lower skin, which are connected by a string-like bulge preventer, is used. The pine is divided into a plurality of sections along the slope direction of the roof surface, and the upper and lower edges of the pine are removably attached to the roof by connecting means, and the bottom of the pine A hot air pipe communicating with each section is provided near the edge, a supply port is opened in each section of the hot air pipe, a discharge port is provided near the upper edge of each section of the pine, and a hot air pipe is provided near the upper edge of each section of the pine. The hot air piping is connected to the hot air boiler via a blower, and is further equipped with a hot air temperature sensor that detects the temperature of the hot air and an outside air temperature sensor that detects the temperature of the outside air. A central control unit is provided which controls the number of rotations of the blower and the fuel supply amount of the hot air boiler based on the number of rotations of the blower.

[Description of Effects] Therefore, during snowfall, the central controller determines the temperature and amount of supplied air according to the outside temperature, and the blower is heated by the hot air boiler and sends the hot air to the hot air piping. Then, the warm air enters the pine from the lower edge of each section of the pine and is discharged from the outlet on the upper edge. During that time, the snow that falls on the pine is heated by warm air and melted, but each section has a string-like swell stopper that restricts the swell, so it does not swell partially and the snow falls. Even with this, the mats swell almost uniformly throughout,
By passing warm air through, even if a snowy area is holding down the pine tree, the snow can melt relatively quickly from around that area.

Since the temperature and amount of hot air are controlled to appropriate values depending on the outside temperature, the amount of heat energy used can be kept to a minimum.

Moreover, in the summer when there is no snow, the pine can be easily removed by opening the coupling means of the upper and lower edges of the pine and pulling the pine in the upstream direction of the hot air pipe. When in use, it can be inserted into the hot air piping and the upper and lower edges connected.

Since the mat can be easily removed and installed in this way, even if the mat becomes damaged, it can be easily replaced.

Note that it is even more preferable to attach a snowfall intensity sensor to the roof to control the amount of hot air supplied.

[Examples] Examples of the present invention will be described below with reference to the drawings.

In Figures 1 to 3, on the roof surface A,
A plurality of (6 in the illustrated example) along the inclination direction of the roof surface.
A bag-like body partitioned into sections 2a to 2f (hereinafter referred to as 2), ie, a mat 1 made of a synthetic fiber sheet, is attached. The lower edge of the mat 1 is removably attached to the fascia B by means of an L-shaped metal fitting 5 provided in each section 2, a turnbuckle 6, and an L-shaped metal fitting 7 provided in the fascia B. The upper edge can be freely connected and separated by a connecting means (not shown). In addition,
Reference numeral 3 denotes a string-like swelling stopper connecting the epithelium 1a and the lower skin 1b of the pine 1 at several points so as to suppress the expansion of each compartment 2 to a predetermined thickness.

On the other hand, hot air piping 8 is provided along the lower edge of the mat 1 to communicate with each section 2. A supply port 9 is provided at the center of each section 2 of the hot air pipe 8, and a discharge port 4 is provided at the upper edge of the mat facing the supply port 9.

The hot air pipes 8, 8 are connected to each other by a communication pipe 10, and the communication pipe 10 is connected to a blower 12 and a hot air boiler 14, which are hot air supply means, through a supply pipe 11.
It is connected to the.

The supply pipe 11 is provided with a hot air temperature sensor 13, and a boiler control panel 15 of the hot air boiler 14,
The blower 12 is connected to a central control device 17, and an outside air temperature sensor 16 provided on the outer wall of the house is connected to the central control device 17.

In FIG. 4, the central control device 17 outputs a control signal to the boiler control panel 15 to adjust the fuel supply amount based on the detection signals from the outside air temperature sensor 16 and the hot air temperature sensor 13, and controls the blower 12. It outputs a control signal to adjust the rotation speed and control the temperature and amount of hot air supplied.

Next, the effect will be explained.

When snowfall begins, the central controller 17 is activated. The central control device 17 determines the temperature and amount of hot air to be supplied in accordance with the outside air temperature, and outputs control signals to the boiler control panel 15 and the blower 12. The hot air boiler 14 and the blower 12 suck outside air, heat it, and supply hot air to each mat 1 from the supply port 9 through the supply pipe 11, the communication pipe 10, and the hot air pipes 8, 8 as shown by the arrows. Supply to section 2 of. The section 2 of the mat 1 is expanded by the supplied warm air from the state shown by the solid line to the state shown by the chain line in FIG. Then, the entire surface of the pine 1 is heated by the warm air, and the heated entire surface immediately melts the snow that comes into contact with it. Therefore, snow melting efficiency is high, and a small amount of heat supply is sufficient.

When there is no need for snow melting, turnbuckle 6
When connecting the metal fittings 5 and 7 by using
1 from the roof surfaces A and A. Thereby, the mat 1 made of synthetic fiber sheet can be prevented from deteriorating over time due to sunlight and outside air, and its durability can be improved.

[Effects of the invention] As described above, according to the invention, the following excellent effects are achieved.

(1) The string-like anti-swelling prevents partial swelling due to the weight of snow and provides uniform heating.

(2) Thermal efficiency is good because the hot air boiler and blower are controlled by the outside temperature.

(3) Because the mat is easy to remove and install,
Can be removed when not in use to prevent deterioration of the mat.

(4) It is easy to repair or replace the mat when it is damaged.
