And is embedded in a passage 9 leading to a road in a general house or the like.

The snow melting and discharging section 3 melts the accumulated snow and causes the melted water to permeate underground. The opening 3a having a rectangular plan view is closed by the transparent body 5, and the bottom 3b is provided with the permeating section 6.

The transparent body 5 has a steel flat plate 5a having a through hole 5b through which hot air and molten water pass, and is detachably mounted on a fitting step 3c of the opening 3a.

Therefore, the transparent body 5 can be removed and the snow accumulated around it can be thrown into the snow melting and discharging section 3 through the opening 3a.

The transparent body 5 is not limited to the flat plate 5a but may be a mesh plate, and a mat or artificial grass may be laid on the upper surface of the transparent plate 5a.

Further, a part of the transparent body 5 is provided with a throwing-in portion 3d for throwing snow accumulated around the snow or snow left by a snow removing vehicle into the snow melting and discharging section 3 without removing the transparent body 5.

The permeation part 6 is for permeating molten water underground,
An infiltration box 6a is provided at approximately the center of 3b, and crushed stones 6b and the like are spread over the bottom thereof.

Further, the bottom portion 3b of the snow melting and discharging section 3 is formed with a predetermined drainage gradient so that all the melted water is collected in the infiltration cell 6a.

As shown in FIG. 6, the permeation part 6 may be formed by opening the bottom part 3b of the snow melting part 3 and laying crushed stones 6b over the entire surface.

The hot air supply device 2 sends hot air, which is housed in the housing part 4 and melts the snow on the permeation body 5, to the melting and discharging part 3, and a signal from a snowfall sensor 7 provided on the roof m of the house or the like. And a multi-stage hot air supply pipe 2a for supplying the hot air to the snow melting and discharging section 3 and a heat source section such as a heater operated by the above, and a fan for blowing the hot air warmed by the heat source section. An intake pipe 2b for supplying air to the heat source is provided.

The intake pipe 2b is for supplying air to the heat source portion, and effectively causes convection of the snow melting and discharging portion 3.

Further, the hot air supply device 2 is set to switch ON when the snow falls and switch OFF when the snow stops (a switch OFF can be set after a predetermined time has passed after the snow stopped) according to a signal from the snowfall sensor 7. If the internal temperature of the snow melting section 3 exceeds a certain temperature (standard is 10 degrees C.), the switch is turned off, and if it is below a certain value, the switch is turned on. It is set.

Further, the hot air supply pipe 2a and the intake pipe 2b are usually provided with a vent hole 2c and an intake hole 2d on the upper surface of the pipe as shown in FIG. 3, but as shown in FIG. Vent 2c
