2. Description of the Related Art Conventionally, there is known a technology relating to a buried type snow melting apparatus in which a snow melting machine is buried in the ground such as in a yard or a garage, and snow is removed, melted and discharged into the snow melting room. I have. In addition, snow accumulated on the passage from the entrance to the road was removed by a scoop or a snow blower, and the removed snow was put into a buried snow melting apparatus, dissolved in sewage or the like, and discharged. However, in the above-mentioned technology, when removing snow accumulated in a place distant from the position where the snow melting device is buried, it is necessary to transport the removed snow to the position where the snow melting device is buried, which is very labor intensive. This was a problem. For example, when a snow melting device is buried in front of a yard or a garage to remove snow accumulated in front of an entrance that is far from the yard or the garage. In addition, in front of the entrance and in the garage, there are relatively many times of passage, and when snowfall occurs, it is necessary to remove snow again before passing.

[0003]

As described above, in places where frequent snow removal is required, piping that allows hot water or the like to pass underground slightly below the surface of the ground is always melted to remove snow. This saves time but increases the cost of raising the temperature of the water. Therefore,
Although it is conceivable to use the heat generated in the buried snow melting apparatus, it is heated only when the snow melts when the burner is operated, so that it is cooled down at other times, so that high-temperature water cannot always be obtained.

[0004]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. The road heating tank 1 is located adjacent to the burner room A and the snow melting room B constituting the buried type snow melting apparatus M.

In the buried snow melting apparatus M according to the present embodiment, the inside of the main body frame 1 is separated into a burner room A and a snow melting room B by a burner mounting plate 11, and the burner 2 is provided inside the burner room A.
And a snow melting plate 3 is arranged inside the snow melting chamber B. The burner 2 and the inside of the snow melting plate 3 are communicated with each other so as to penetrate the burner mounting plate 11. The snow melting plate 3 is supported by supports 16 and 17 and is supported in a floating state. The upper part of the buried snow melting device can be closed by a lid 35.

The snow melting plate 3 is formed in a substantially pentagonal shape when viewed from the front, and a hot air hole 3 is formed on a slope (side surface) of the snow melting plate 3.
a, 3a, etc. are opened so that hot air from the burner 2 is blown obliquely upward to melt the snow put into the snow melting chamber B, and the snow contacting the slope of the snow melting plate 3 is also melted. And fall along the slope as water. The edge of the ridge 3b at the upper end of the snow melting plate 3 is joined by joining the ends of the steel plates as vertical sides, and a gap is provided on the joining surface with a spacer (not shown) interposed therebetween. The hot air is blown upwards as the hole 3c, and the hot air from the hot air hole 3c and the snow at the ridgeline portion 3b contact each other, so that the injected snow is pressed from above and solidified. It is cracked, falls along the slope by its own weight, and is melted by the snow melting plate 3.

A cooling water chamber 4 is provided on the front surface of the snow melting plate 3 in accordance with the extension of the snow melting plate 3. The flame from the burner 2 prevents the front surface of the snow melting plate 3 from being deformed.

Part of the dissolved water is discharged from a drain 12 opened at the lower part of the snow melting chamber B to a pump chamber C formed at one corner of the main body frame 1, and the bottom of the snow melting chamber B is cooled.
The snow melted in the snow melting chamber B is stored in the pump chamber C from the drain 12 by lowering the side. The drain 12 is covered with a net to remove dust and the like.

In the pump chamber C, there is disposed a shower pump 5 which automatically operates when a certain amount of water accumulates, and a shower pipe 15 is connected to a discharge port of the shower pump 5.

By operating the load heating pump 7, the heat exchange liquid heated in the load heating pipe 8 is caused to flow, and the heat warms the ground to melt the snow accumulated on the ground. Then, the heat exchange liquid cooled by the heat exchange is returned to the load heating tank 10 through the load heating pipe 8.

The load heating pump 7 may be operated only while the burner 2 is operating.
It is also possible to provide a temperature sensor S in the load heating tank 10 so that the temperature sensor S operates until the temperature drops to the set temperature. Further, the road heating tank 10 is buried in the ground, and heat can be stored by attaching a heat insulating material around the tank. By operating the load heating pump 7 only when necessary, A timer T is connected to the circuit 21 so that the timer is turned on several hours before commuting or commuting in consideration of the time of snow melting, and the road heating pump 7 is operated to commute to commuting or commuting. Sometimes, it is possible to set so that the snow melts, and to melt the snow in the passage or the like.
