Abstract

PURPOSE:To save effectively energy in removing snow by keeping water having a slightly higher temperature in pools provided to the bottom of sloping roofs and, at the same time, floating snow on the roof down the pool with a sprinkler to melt the snow. CONSTITUTION:The longitudinal V channel water keeping pools 3 are formed to the common bottom of sloping roofs 1 and 2. Then, a plurality of sprinkler nozzles 4 are provided to each of roof tops. After that, hot water having a higher temperature than 0 deg.C is supplied to each of pools 3 and sprinkers 4 from pipings through cocks 5. In addition, temperature sensors are arranged on the insides of the pools 3, and the cocks 5 are opened and closed to control automatically freezing. The snow is dropped into the pools 3 by means of empty weight or water sprinkling through the sprinklers to melt the snow. According to the constitution, operations such as snow-removing, conveyance, etc., are not required and, at the same time, the sloping roof can be used as a panel heater type roof cooling device and hot water supply device during the summer time.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a snow melting roof, particularly to a snow melting roof structure in relatively warm and cold snowy regions.

[Conventional technology]

In comparatively warm and cold power-accumulating areas, such as areas with heavy snowfall on the banks of the Hibuki Sea, snow removal from roofs and roads is a major daily problem, and various methods have been adopted. Considering the ancillary work of mechanical work, magneto-electricity is the most preferred counterpart, and water spraying or electrical heating and other methods have been tried.

[Three problems to be solved by the invention] However, it is impossible for electric heating to be widely used due to energy issues, and simple sprinkling of water on necessary areas such as roads or roofs is insufficient. The reality is that the amount of water consumed is large, which poses a cost problem, and it is also extremely difficult to recover and reuse water through circulation.

Of these, the most practical and most effective method has traditionally been to remove snow from a roof, if there is a pond around the house, to drop the snow directly into it and let the pond water, which is warmer than 0°C, melt the snow. It is said that there is.

Naturally, many ordinary houses cannot be expected to have such ponds, so this invention applies this principle to roofs to effectively melt snow without requiring mechanical work. The purpose is to provide the means.

(Means for Solving the Problems) Therefore, in this invention, instead of Moeki Pond,
This objective is achieved by storing water at a slightly higher temperature in the lower part of the sloping roof to melt fallen snow, and by arranging sprinkler nozzles at the top of the roof.

[Effect]

With the above structure, in the roof according to the present invention, snow on the roof is melted by flowing down into the water pool with the help of the sprinkler nozzle, and is drained to the ground or circulated as necessary. can effectively solve the burden.

Furthermore, by using this inventive facility as a panel heater-type roof cooling system in the summer, it is possible to save cooling energy and to further warm the waste water (
You can also use hot water.

〔Example〕

The present invention will be explained below based on examples.

FIG. 2 shows a schematic perspective view of an embodiment of a snow melting roof according to the present invention, and FIG. 1(a) shows a schematic diagram of the system configuration thereof.

FIG. 1(b) shows another embodiment of the section F in FIG. 1(a).

(41I construction) In Figure 1.2, 1.2 is each sloped roof forming a mountain shape on the house H, 3 is each V groove-shaped water formed in the longitudinal direction of the common lower part of each roof 1.2. The reservoir pools 4 are a plurality of sprinkler nozzles arranged at the top of each roof. Each pool 3 and sprinkler 4 have a water source W
Tap water at a temperature higher than 0° C. is supplied from each pipe via the cock 5, and water is drained from the bottom of each pool 3 to the above-ground GD via pipes.

In addition, for the supply/drainage shown in FIG. 1(a) above, instead of the water supply W, a water tank 6 is provided in the above-ground GD (preferably underground) as shown in FIG. may be stored and circulated through the hop 8. 9 indicates a drain cock.

In addition, each of the above-mentioned pool 3 devices is unitized so that it can be manufactured in a factory.

(Function/Effect) The snow accumulated on the roof slides down along the slope of the roof into the pool 3 at the bottom due to its own weight and melts. Also both roofs 1.2
When a large amount of snow has accumulated on the top, water is sprayed from each sprinkler 4 as necessary to break the bridging of snow to both sides of the top and help it slide into the pool. The melted water may simply overflow and be placed at a suitable location on the ground GD.

The supply of tap water W to each pool part 3 is automatically controlled by, for example, installing a temperature sensor (not shown) in the pool 3 and opening the cock 5 before the water temperature reaches the freezing temperature of 0°C to prevent freezing. It is carried out.

Further, as shown in FIG. 1(b), similar temperature control can be performed even when a water tank 6 is specially installed on the ground.

Furthermore, in the summer, these pool facilities can be used as a panel heater-type roof cooling system, and the drainage water can be used as washing water, or the water tank 6 shown in Fig. 2(b) can be used as a children's pool, etc. On the other hand, cooling energy can be saved due to the exhaust heat from the roof cooling.

(Other Examples) In Fig. 1.2, an example of a typical roof shape was explained, but these roof shapes are not limited to only those on the national side. It goes without saying that various modifications may be made, such as forming each pool 3a by dividing the slope 1a into saw-like shapes as shown in FIG.

(Effects of the Invention) As explained above, according to the present invention, snow on the roof can, if necessary, slide down into the pool provided at the bottom of the roof with the help of sprinkler nozzles, melt the snow, and reach the ground. Since the water is drained and circulated as needed, mechanical work such as snow removal, snow removal/transportation, etc. is no longer required, and by using this facility in the summer, you can save on air conditioning energy and use hot water. It becomes possible to use it.
