Description

[Detailed Description of the Invention] The work of removing snow from roofs in snowy regions is hard work and requires a lot of procurement. Elderly households in particular have difficulty removing snow from their roofs in the winter.

Conventionally, various methods have been adopted to save labor in the work of removing snow from roofs, and as a natural sliding method, steeply sloped roofs made of metal shingles have generally been adopted.

This method had the disadvantage that if the outside temperature was low, snow would freeze on the roof and prevent it from falling naturally.

The present invention guides hot air generated from various types of stoves installed indoors to the top of the roof, and quickly lowers the hot air along the underside of the attic to warm the entire roof. The purpose is to melt roof snow that has frozen and adhered to the roof material surface, reduce the frictional force between the roof surface and roof snow, promote the sliding of roof snow, and save the labor required to remove roof snow. be.

To explain the present invention with reference to the drawings, as shown in FIGS. 1 and 2, a hot room O is provided between the roof 4 and the ceiling 1, a side wall 6 is provided between the outer wall 5 and the indoor room S, A descending air chamber K is provided which forms a vertical space and communicates with the upper hot air chamber, and a cold air outlet 7 is opened at the lower part, and a side cover 10 is attached below the roof top T so that it can be opened and closed. A hot air inlet 2 having a required notification area is opened in the ceiling 1 where the hot air inlet 2 is located, and a cylindrical rising wall 3 having a required height H is connected and fixed to the upper part of the hot air inlet 2. The canopy 9 is installed so that it can be opened and closed, but the canopy 9 and side lids 10 are opened when sliding down snow from the roof in winter, and closed at other times. The attic ventilation hole 17 is closed to prevent air from escaping outside the building. The height difference D between the hot air inlet 2 provided in the ceiling and the cold air outlet 7 provided in the descending air chamber K is made as large as possible.

In the embodiment of the present invention, as shown in FIG. 3, the air in the room S heated by the heat source N such as various subs placed on the floor 8 of the room S becomes lighter and rises as shown by the dotted arrow, and rises to the hot air inlet 2. The warm air is guided to the back side of the roof top T by the rising wall 3, and this warm air warms the small roof, roof members, etc. on the back side of the roof top T, and the snow 16 on the roof top T gradually melts due to heat transfer. At the same time, the roof snow on the left and right sides of the ridge part is separated, and at the same time, the melted water flows in the direction of the slope of the roof surface.The door root snow 16 stuck to the roof surface is melted, and the frictional force with the roof surface is reduced. , a sliding force P of the roof snow is generated as shown by the arrow on the roof surface, causing the roof snow 16 to slide down.

Heat is radiated at the top of the roof T, and the slightly cooled air flows down along the back side of the roof in the direction of the slope, warms each member of the attic, becomes cold air, passes through the descending air chamber K, and enters the room S from the cold air outlet 7. Move to.

In this way, due to the heat source N, the airflow E changes from room S to warm air entering RO2.
→ Rising wall 3 → Warm air chamber O → Descending air chamber K → Cold air outlet 7 → Indoor S, the air circulates smoothly and quickly to warm the roof and promote the sliding of roof snow 16.

Figures 4 and 5 show an example in which the inside of the curved roof 21 is used as a second-floor living room, and a side wall 6 that is approximately parallel to the curved roof is installed between the curved roof 21 and the room S, and the roof 4 and The space slanted with the side wall 6 is a descending air chamber K, and a hot air inlet 2 is provided in the ceiling below the cold air outlet 7 and the roof top T at the bottom, and a cylinder with a required height H is provided above the hot air inlet. A rising wall 3 in the shape of a shape is provided, a hot air chamber 0 is provided between the ceiling I and the roof 4, and a heat source is provided on the second floor floor 8, and a heat source N is provided on the first floor floor 8 shown in Fig. 3. It has the same effect.

In order to make the roof snow 16 slide down, it is important to melt the snow on the top of the roof T first.In the present invention, since warm air is directly guided to the top of the attic by the rising wall 3, the evening at the top can be made early. You can do it without understanding it. In addition, due to the difference in height between the cold air outlet 7 and the hot air inlet 2 provided at the bottom of the descending air chamber K, the paths of the ascending air current and descending air flow become fixed in the same direction, and the air flow E inside the room S and the hot air room O becomes confused. It is possible to quickly and smoothly warm up each room with frozen roof snow without melting the roof snow that has frozen on the roofing material.

As described above, the present invention can quickly warm up the roof using a heat source N such as a heater and slide down the roof snow 16 using a simple method, thereby saving the labor required for removing snow from the roof in winter.
