When the burner 21 does not burn and the burner 21 does not burn, the burner non-ignition lamp 47 is lit. If the abnormality is removed and the abnormality reset switch 48 is pressed, the water level, the heating abnormality lamp 46 or the burner non-ignition lamp 47 is turned off and operation is possible State.

The voltage drop lamp 44 is turned on when the battery of the remote controller 40 is exhausted.

Next, the operation together with the method of use will be described.

First, the operation lid 12 and the snow melting chamber lids 15 and 16 are opened, and a predetermined amount of water up to the specified water level L is injected into the snow melting chamber 3 only at the beginning of the season. Operate the remote control 40 and operate the submersible pump 31 with the sprinkling on switch 52, and then burner with the combustion on switch 49.
Ignite 21.

At this time, an operation lid 12 which can be opened and closed is provided above the buried snow melting machine 1, and a light receiving element is provided inside the operation lid 12.
Since the operation lid 12 is provided, the operation lid 12 is reduced in weight, so that there is no difficulty in opening the work even for the elderly.

When the operation cover 12 is opened, the remote controller 40 is operated from a position away from the snow melting machine 1, and the signal transmitted from the light emitting element 41 of the remote controller 40 is received by the light receiving element 13 of the snow melting machine 1. Since the driving operation is performed, the remote controller 40 can be operated while standing, so that there is no pain to bend down for the operation.

When snow is thrown into the snow melting chamber 3, snow is melted by heat radiation from the furnace body 22, exhaust from the furnace body 22 and water sprinkling from the discharge port of the water sprinkling pipe 32, and the snow melting water W exceeding the specified water level L
Naturally flows out of the drain port 7. The operator collects snow one after another and puts it into the snow melting room 3.

At this time, the signal transmitted from the light emitting element 41 of the remote controller 40 is received by the light receiving element 13 of the snow melting machine 1 to perform the driving operation. Therefore, when the operator leaves the snow melting machine to collect snow, there is no fear that an unexpected accident occurs when another person other than the original operator operates the switch.

An intake cylinder 14 for supplying air to the burner 21 is provided inside the operation lid 12, and a light receiving element or a light emitting / receiving element 13 is provided on a side surface of the intake cylinder 14. The operation lid 12 is closed during operation. Automatically stops the operation of the burner 21, the burner 21 is extinguished without operating the remote control 40 even if the operation lid 12 is inadvertently closed, so there is no risk of the burner 21 burning incompletely. .

Even if the snow melting machine 1 stops during the snow melting work,
A light emitting / receiving element 13 is provided inside the operation lid 12, and when an abnormality occurs in the snow melting machine 1, a signal transmitted from the light emitting / receiving element 13 of the snow melting machine 1 is received by the light receiving element 42 of the remote controller 40 and the remote controller 40 has an abnormality. Is displayed, the abnormality is displayed on the remote controller 40 held by the operator, and the details of the abnormality can be immediately recognized. Therefore, it is possible to cope with the situation without going to the snow melting machine 1 to confirm the abnormality.

When the snow melting operation is completed, the burner 21 is extinguished by the burn-off switch 50 of the remote controller 40 and the sprinkler switch 53 is turned off.
Then, the operation of the submersible pump 31 is stopped, and the operation lid 12 and the snow melting chamber lids 15, 16 are closed and locked. In order to drain the water in the snow melting chamber 3 and the pump chamber 4 only when the season is over, the valve between the submersible pump 31 and the water sprinkling pipe 32 is switched to operate the submersible pump 31 to drain water.

In the above embodiment, the example in which the light emitting / receiving element 13 for emitting light and light is provided inside the operation lid 12 has been described. However, when only the operation of the snow melting machine 1 is performed by the remote controller 40, the operation lid is used. It suffices that only the light receiving element is provided in 12.

Although the light emitting element 13 and the light emitting element 41 use infrared light, they may use visible light or radio waves.

Further, the example in which the proximity switch 8 is used to automatically stop the operation of the burner 21 when the operation lid 12 is closed during the operation has been described. However, the operation lid 12 is used like a limit switch or a photoelectric switch. What is necessary is just to be able to detect that is closed.
