However, the above-mentioned conventional buried snow melting apparatus melts snow by domestic drainage or melts snow by heating temperature in the house. The snow melting power is weak, and sufficient snow melting can be performed in a short time. It was impossible to do. In the present invention, high-temperature hot air is blown to a snow-melting cylinder by a burner, snow is thrown on the snow-melting cylinder, and snow is melted in a short time by the heat around the snow-melting cylinder and the blown hot air. In addition, conventional mobile and ground-mounted snow melting machines require a great deal of labor for elderly people and children due to the high position of the snow opening, and also require a long working time because the amount of snow to be thrown at once is small. It also required a large space for storage when not in use.

According to the present invention, a box is buried underground to constitute a snow melting room, a pump room or a burner room, and the cover can be opened to allow snow melting by throwing snow underground. In a season other than the winter season, the storage state can be set by simply closing the lid. In addition, the operation box that controls the power supply to the burner and pump that make up the snow melting device is provided on the back of the lid that must be kept open during snow melting work, thereby preventing erroneous operation. Is what you do.

FIG. 6 shows that the lid 5 is divided into 5 ′ and 5 ′ front and rear, and hinges 43, 43 are provided between the front end and the rear end and the side of the box 4.
43, and pins 44 on both sides of the central end of the lids 5 ', 5'.
On the other hand, arc-shaped guide grooves 4c, 4c are formed on the inner surface of the box 4, and a locking unit C is provided at the upper end of the guide grooves 4c, 4c as shown in FIG. 5 ', 5'
Are configured to be locked. That is, in the locking unit C, the locking pin 45 is urged by the spring 46 and the locking pin 45
Is pivotally supported by an arm 47, and the arm 47 is rotated about a shaft 49 by the rotation of a lever 48.
5, the locking of the pins 44, 44 is released to open the lids 5 ', 5'. 50 is a wire which is pulled when closing.

As shown in FIG. 8, instead of the locking unit C, locking shafts 51, 52 are attached to the lids 5 ', 5'.
And insert the ends of the locking shafts 51 and 52 into the box 4
And the cover shaft 5 can be opened by releasing the lock by sliding the lock shafts 51 and 52. The configuration of the snow melting device A is a snow melting cylinder 2
6 and a burner portion H, and the snow melting cylinder 26 is
And is placed on the bases 27 and 27,
The upper plate 6 is doubled with 26a and 26b, and the air outlets 26c... 26d are opened at appropriate intervals. The upper plate 26a is provided with irregularities in side view. The melting water flows down to the partition frame 6.

A burner section H has a burner chamber 12 and a fan 2 in a burner chamber 29 communicating with the snow melting cylinder 26 on the side surface.
2 and heat generated from the burner 12 is
, Into the snow-melting cylinder 26, and the exhaust ports 26c.
6d... Are discharged. In order to send air to the burner section H, suction ports 29a, 29a,.
6, air can be sucked through the communication port 1a.

In order to melt the snow more efficiently by the snow melting device A, a discharge pipe 53 connected to the submersible pump 3 extends from a lower part of the inclined plate 31 to the air duct chamber 16. Branch pipe (cheese) 5
Branching at 4, one is discharged to a sewer 10 via a valve 8, and the other is connected to a shower pipe 11 via a valve 9. The valves 8 and 9 can be adjusted by sticking their hands through the upper opening of the air duct chamber 16, and about half of the valves are discharged from the sewage channel 10 and the rest are sent to the shower pipe 11, and the snow melting chamber 1 is adjusted. It is gushing inside. The shower pipe 11 is piped around the inside of the upper part of the box 4 and is provided with jet ports 11a, 11a,.
-It is configured such that more warm water is spouted into the snow melting chamber 1.

Further, as shown in FIG. 9, the snow melting apparatus A can be provided in the snow melting chamber 1 with a snow melting cylinder and a burner part from which the traveling part of the conventional mobile snow melting apparatus A 'is removed.
When the snow melting chamber 1 buried underground is provided in front of the garage B as shown in FIG.
A fuel tank 24 and a power supply box 19 are provided.

When the snow melting chamber 1 buried in the ground is opened, the snow can be thrown directly from a side road or a sidewalk as shown in FIG. When the snow accumulates on the slope plate 31 on the inclined plate 31 and the sensor 32 is turned on, or when the work switch 34 of the operation box 20 is manually turned on, the burner 12 is ignited and air is supplied to the air duct chamber. 16, the warm air is blown out and the exhaust air outlets 26 c.
6d ... melts snow from below.

The melted hot snow water is discharged from the drain port 6a and collected in the pump chamber 2, and is sucked upward from the discharge pipe 53 by the operation of the submersible pump 3 in the pump chamber 2; Some of the sewage ditch 10
And the rest is squirted from the shower pipe 11
The snow inside is melted from above by a shower to promote snow melting.

[0018]

According to the above configuration, the present invention has the following effects. First, since the operation box 20 in which the operation switch 34 is disposed is provided on the back surface of the lid 5 that closes the opening of the snow melting chamber 1, the snow melting work is started only when the lid 5 is opened. It is not possible to operate the burner 1 with the lid 5 closed due to erroneous operation.
Thus, the possibility that the incomplete combustion state of the burner 12 occurs inside the burner was eliminated. Second, the lid 5
The operation box 20 is attached to the rear side of the box, so that even if an operator falls inside the snow melting chamber 1 during snow melting work, the operation box is exposed at a position protruding from the ground. By operating the 20 work switches 34, the burner 12 can be extinguished immediately and the device can be made safe. Third, when the operation box is arranged at a position distant from the buried snow melting device and exposed to the ground, it is necessary to wire with a wire harness between the buried snow melting device and the operation box. Although work such as embedding this wire harness in the soil is necessary, the operation box 2
By attaching 0 to the back surface of the lid 5, the operation box 20 can be exposed on the ground during snow melting work, and
All that is required is to incorporate a short wire harness inside the buried snow melting device. Fourth, since the lid serves as the ground surface as it is during storage during winter, the vehicle can pass over it and humans can walk. Even in this state, the lid and the box Since the surroundings are protected by the body 4, the operation box 20 and the work switch 3
4 is not damaged. Fifth, since the operation box 20 is fixed to the lower surface of the lid, even when rainwater or groundwater accumulates inside the box 4, unless the operation box 20 overflows from the box 4, the operation box 20 is They will not be submerged.
