Description

  The present invention generally relates to snow melting devices. More specifically, the present invention relates to a snow melting device for a roof that melts snow that has fallen on a roof of a house or the like.

  In snowy areas, how to deal with the accumulated snow is an important issue. In particular, in the work of removing snow accumulated on the roof of a house, accidents have occurred every year, such as sliding off the roof during the work. In recent years, an attempt has been made to incorporate a heater into a roof and melt snow accumulated on the roof by heat generated by the heater. In addition, some houses have been devised by making the roof steep so that the snow that falls on the roof slides down naturally.

  However, the method of heating with a heater has the disadvantage that the electricity bill during winter increases. In addition, when the roof is steep, there is a disadvantage that snow falls on the boundary with the neighboring house. As described above, there is no effective means for efficiently treating the snow on the roof. The present invention has been devised in view of such a situation, and an object thereof is to provide a snow melting device for a roof that can efficiently melt the snow on the roof with little maintenance cost. It is said.

  The snow melting device for roof according to claim 1 of the present application is located between the roof plate and the ceiling, and is disposed at a ventilation path having an inlet and an outlet, and at the inlet of the ventilation path, and air is introduced into the ventilation path. And a control unit having a temperature sensor for detecting the outside air temperature and a controller for outputting an operation signal to the fan based on the temperature obtained from the temperature sensor, and the outside air temperature becomes equal to or higher than a predetermined temperature. In this case, the fan is operated to send air into the ventilation path, thereby melting the snow located on the roof plate.

  The snow melting device for roof according to claim 2 of the present application is the device according to claim 1, wherein the air sent into the ventilation passage moves on the side facing the roof plate, and interferes with a lower portion of the ventilation passage. A plate is provided.

  The snow melting device for roof according to claim 3 of the present application is characterized in that, in the device of claim 1 or 2, a snow stop cover is disposed at an eaves tip located at a tip of the gentle slope of the roof plate. Is.

  The snow melting device for roof according to claim 4 of the present application is characterized in that, in the device of claim 3, the lower end of the eaves is bent so as to be inclined obliquely downward.

  According to the present invention, snow falling on the roof can be efficiently melted with little maintenance cost. Further, since the snow cover is installed at the eaves and further bent so that the lower end of the eaves is inclined obliquely downward, it is possible to avoid the occurrence of wiggles at the eaves as much as possible.

  Next, a snow melting device for roofs according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a schematic cross-sectional view schematically showing a snow melting device for roof according to a preferred embodiment of the present invention. The snow melting device for roof according to the present invention includes a ventilation path 10 in an attic (in other words, a space located between a roof plate 12 and a ceiling 14). In addition, the ventilation path 10 does not need to install a pipe etc. in an attic, and as shown in FIG. 1, it is sufficient if a certain space from the entrance 10a to the exit 10b is installed in the attic.

  A fan 16 for sending air into the ventilation path 10 is disposed at the inlet 10 a of the ventilation path 10. The fan 16 may be of a normal type.

  In the snow melting device for roof according to the present invention, it is preferable that the roof plate 12 is composed only of a tin plate in consideration of heat transfer. Moreover, it is preferable to provide a gentle slope in the roof plate 12 so that the snow melt water flows easily when the snow accumulated on the roof plate 12 melts. Preferably, the slope of the roof plate is about 25/1000 to 40/1000 (see FIG. 2 (a)).

  As the roof plate 12, a folded plate structure type (see FIG. 2 (b)) provided at a position where a joint portion between adjacent roof plates is high is used.

  It is preferable to provide a baffle plate 18 at the lower part of the air passage 10 so that the air sent into the air passage 10 moves on the side facing the roof plate 12. By providing the baffle plate 18, the air moving in the ventilation path 10 is blocked by the baffle plate 18 and moves upward, and moves in the ventilation path 10 along the side facing the roof plate 12.

  The snow on the roof plate 12 is heated by the air passing through the ventilation path 10 and becomes water, and flows down to the ground through the eaves. However, since the roof plate 12 of the folded plate structure type is used, When snow invades the valley of the roof plate 12, the flowing water and snow are mixed and frozen, and there is a risk that icicles are generated at the eaves. Therefore, in the snow melting device for roof according to the present invention, the snow stop plate 22 is attached to a location adjacent to the eaves of the valley portion of the roof plate 12 and the snow stop cover 20 is provided so as to cover the eaves of the valley portion of the roof plate 12. It is preferable to install (see FIG. 3). As shown in FIG. 3B, a gap is provided between the snow stop plate 22 and the roof plate 12 so that the water melted by snow flows down. Reference numeral 24 is a support material for attaching the snow stop plate 22. By installing the snow stop cover 20 and the snow stop plate 22 in this manner, snow does not enter from the eaves of the valley, so that the possibility of occurrence of wiggle at the eaves can be reduced.

  Preferably, the lower end 12a of the eaves is bent so as to be inclined obliquely downward. Thereby, draining becomes favorable and the possibility of occurrence of icicles can be further reduced.

  In the example shown in FIG. 1, the inlet 10 a and the outlet 10 b of the ventilation path 10 are respectively installed under the eaves. However, a pipeline 25 communicating with the ventilation path 10 is installed along the outer wall, and is connected to the pipeline 24. You may comprise so that the fan 16 may be arrange | positioned (refer FIG. 4). Further, the second fan 16 ′ may be disposed between the room and the ventilation path 10 (or the pipe line 25) in order to use indoor warm air.

  The roof snow melting device of the present invention also includes a control unit 26. The control unit 26 includes a temperature sensor 26a for detecting the outside air temperature, and a controller 26b for outputting a signal for operating the fans 16 and 16 'when the temperature obtained from the temperature sensor 26a exceeds a predetermined temperature. Have.

The operation of the snow melting device for roof of the present invention configured as described above will be described. First, the fan operating temperature of the control unit 26 is set to t ₀ in advance. When the outside air temperature rises from t ₁ to t ₀ , the fan 16 is actuated by an actuation signal from the controller 26 b and air is sent into the ventilation path 10. The air sent into the ventilation path 10 is warped toward the roof plate 12 by colliding with the baffle plate 18 and efficiently heats the roof plate 12. By the heated roof board 12, the snow on the roof board 12 melts into water and flows down to the ground through the eaves. On the other hand, the snow on the roof plate 12 that has not melted is blocked by the snow stop plate 22 and does not reach the eaves.

  The present invention is not limited to the above-described embodiments of the invention, and various modifications are possible within the scope of the invention described in the claims of the utility model registration, and these are also within the scope of the present invention. Needless to say, it is included.

  In addition, it is preferable to provide the inlet 10a of the ventilation path 10 in the south side so that solar heat can be utilized effectively.
