DESCRIPTION OF THE PREFERRED EMBODIMENTS The objects and constitutions of the present invention are as described above, and the constitution of the embodiment shown in the attached drawings will be described.
FIG. 1 is a front sectional view of an embedded snow melting apparatus of the present invention, FIG. 2 is a side sectional view of the same, and FIG. 3 is a plan view of the same with a lid removed.

The snow melting apparatus of the present invention digs up an appropriate place in the premises and fills it except for an opening above the main body frame 4, and a heat insulating material 25 is attached to an outer surface of the main body frame 4 to keep the heat. The effect is enhanced. A lid 5 is pivotally connected to one side of the opening via a hinge 24. When the lid 5 is closed, the user can freely walk on the snow melting device so that the snow melting device does not interfere. I have. The lid 5 is a damper 2
7, so that it can be easily opened and closed. 23 is a handle. On the back surface of the lid 5, an operation box 22 for a snow melting cylinder A and a submersible pump is provided.

The inside of the main body frame 4 is divided into right and left by a partition plate 3, one side being a snow melting chamber 1 and the other side being a shower snow melting chamber 2. A machine frame 6 is provided inside the snow melting room 1,
A snowmelt cylinder A is installed inside. The snow melting tube A is a burner 2
6, the burner 26 projects into a duct 30 separated by a side plate 29 so that air can be sucked in, and warm air and combustion gas emitted from the burner 26 pass through the snow melting cylinder A. Are blown upward from the blowing holes 31a, 31a,... Opened in the upper plate 31, so as to melt the snow in the snow melting chamber 1, and the structure of the snow melting cylinder A also serves as a chimney and is simplified. . The water after the dissolution is discharged from the drain 7 opened in the bottom of the machine frame 6, and the bottom of the machine frame 6 is lower on the burner side. Then, the first pump chamber 8 is formed by being dug deeper in one corner of the main body frame 4, and the snow melted in the snow melting chamber 1 is stored. The drain 7 is covered with a net or the like to remove dust and the like.

An automatic submersible pump 9 is provided in the first pump chamber 8 and automatically operates when a certain amount of water accumulates. A pipe 10 communicates with a discharge port of the submersible pump 9. The other end of the pipe 10 communicates with shower pipes 11 and 12.

The shower pipe 11 is a shower pipe 12
The pipe diameter is made smaller, so that only a small amount is discharged and only about 25% of the whole is discharged, and pipes are piped around the upper surface along the wall surface of the snow melting chamber 1 so that the snow put into the snow melting chamber 1 is formed on the side plate. It falls smoothly on the snow melting cylinder A so that it does not adhere and fall.

Since the shower pipe 12 has a large pipe diameter, it can discharge a large amount of warm water. The shower pipe 12 is piped around the other side of the shower snow melting chamber 2 which is partitioned by the partition plate 3. It is discharged to melt the snow that has been thrown in. A drain 13 is also provided on the lower surface of the shower snow melting chamber 2, and a second pump chamber 14 is provided below one corner of the lower surface.

An automatic submersible pump 15 similar to the above is disposed in the second pump chamber 14, and a pipe 16 communicates with a discharge port of the submersible pump 15, and communicates with a shower pipe 18 at an intermediate portion of the pipe 16. Then, the snow in the center of the shower snow melting room 2 is melted. The end of the pipe 16 exits from the body frame 4 and faces the sewage groove 20 to discharge the snowmelt water.

In such a configuration, the snow removed can be put into the snow melting chamber as it is by opening the lid 5 without lifting, and the snow put into the snow melting chamber 1 is placed on the upper plate 31, The combustion gas from the burner 26 is blown out from the blowing holes 31a, 31a,... Through the snow melting cylinder A. At this time, since the snow melting cylinder A plays the role of a chimney, the flow of the combustion gas becomes vigorous and the snow melting occurs. And the heat melts the snow and falls to the bottom of the machine casing 6. The machine frame 6
Since the bottom portion is slightly lowered on the burner side, it is heated while being stored there, and hot water of about 25 degrees is drained from the drain 7 and stored in the first pump chamber 8.

When a certain amount of hot water in the first pump chamber 8 accumulates, the submersible pump 9 operates to reach the shower pipes 11 and 12 via the pipe 10, and the discharge amount is small because the pipe diameter is small from the shower pipe 11. And about 25% of the total amount of snowmelt water is discharged to the vicinity of the side plate of the snowmelt chamber 1 so that the snow falls smoothly downward and reaches the snowmelt cylinder A.

Most of the hot water is discharged from the shower pipe 12 from above the shower snow melting chamber 2 toward the center thereof.
The snow in the shower snow melting room 2 is melted. The dissolved water enters the second pump chamber 14 from the drain 13,
When a certain amount or more is accumulated in the second pump chamber 14, the submersible pump 1
5 is operated, and a part from the pipe 16 is a shower snow melting room 2
Discharged from a shower pipe 18 provided in the middle part of the inside, the snow adhering to the side surface is melted to lower the snow in the shower snow melting chamber 2 downward.
Is discharged. Although the temperature of the water discharged here is about 5 degrees, unlike the case of discharging on the road surface, there is no problem because the water flows directly into the sewer.

[0015]

According to the present invention, the following effects can be obtained. First, since the cylindrical snow melting tube A is disposed inside the snow melting chamber 1 and the upper and side portions of the snow melting tube A can be used as a snow melting space, the melting snow is Since it falls along the side surface and falls and is immersed in the snowmelt water stored at the bottom of the main body frame 4, it can receive the snowmelt effect of the snowmelt water, so that the snowmelt heat efficiency can be improved.

Secondly, the thrown snow is disposed on the upper surface and the side surface of the snow melting tube A, and the snow that has accumulated in a bridge shape on the side surface of the snow melting tube A loses heat of the snow melting tube A. Blow hole 3
Since the side of the snow melting tube A is instantaneously melted by the hot air from 1 a, the bridge collapses and immediately slips down from the side surface of the snow melting tube A toward the bottom of the main body frame 4. As a result, the snow melting speed can be increased.

Third, the flue gas is guided to the snow-melting chamber 1 through the snow-melting cylinder A, and is blown out from the blowout holes 31a. The snow melting ability can be improved by the amount of the combustion exhaust gas.

Fourth, since the snow melting cylinder A is configured to discharge the combustion exhaust gas from the burner 26 as an outlet, the chimney is not required, and the combustion exhaust gas is brought into contact with the snow in the snow melting chamber to improve the snow melting ability. It is intended to reduce costs with a simple configuration.
