Abstract

PURPOSE:To improve safety by embedding a snow melting chamber having an open and close lid into the ground, opening and communicating a hot air discharge port of a burner into a snow melting cylinder, and forming a passage for snowmelt water between the lower face of the snow melting cylinder and the bottom face of the snow melting chamber. CONSTITUTION:The upper section of a snow melting chamber 1 becomes a space for melting snow between a snow melting cylinder 26 and it, and a space between a bottom section of the chamber 1 and the snow melting cylinder 26 becomes a passage for snowmelt water. For this reason, snow charged into an upper section of the snow melting cylinder 26 does not prevent movement of snowmelt water or snowmelt water does not reach a burner and does not extinguish fire. Since a work switch 34 is arranged on the back of a lid 5 of the snow melting chamber, the snow melting work cannot be started except when the lid 5 is opened. For this reason, it is possible to prevent ignition of the burner 12 while the lid 5 is closed and danger that incomplete combustion occurs. In addition, even if a worker falls into the chamber 1, the burner 12 is extinguished immediately by operating the switch 34. Consequently, it is possible to prevent unexpected accidental fire of the burner and extinguish fire easily as required.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement of an operation box for controlling ignition / extinction of a burner in an embedded snow melting device.

[0002]

2. Description of the Related Art Conventionally, a technique relating to a buried snow melting apparatus has been known. For example, JP-A-62-2
It is the same as the technique described in Japanese Patent Laid-Open No. 580909, Japanese Utility Model Laid-Open No. 62-129426, and Japanese Patent Laid-Open No. 49-129327. Further, as a conventional technique, the technique shown in FIG. 12 has been publicly known for a snow melting machine that melts snow with a burner. That is, the snow melting tank 57 is provided on the traveling device including the running wheels 55 and the sleds 56, the snow melting tank 58 is internally provided in the snow melting tank 57, and the burner 5 is provided on the side of the snow melting tank 58.
9, a hopper 60 was disposed on the snow melting tank 57, and the snow introduced from the hopper 60 was melted in the snow melting tank 58 and discharged from the drain pipe 61.
62 is a fuel tank, 63 is a handle, 64 is an operation box, and 65 is a stand.

[0003]

However, the above-mentioned conventional buried type snow melting apparatus is one that melts snow by domestic drainage and melts snow by the heating temperature in the house, has a weak snow melting power, and sufficiently melts snow 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 and snow is thrown on the snow melting cylinder to perform the snow melting in a short time. In addition, the conventional snow melting method using a mobile snow melting machine requires a great deal of labor for the elderly and children due to the high snow throwing opening (hopper), and the work time is long due to the small amount of snow throwing at one time. It was necessary and required a large space for storage when not in use. The present invention facilitates the introduction of snow into the snow melting tank by burying the snow melting device in the ground, and the passage of the snow melting water is formed below the snow melting tube and between the bottom of the snow melting chamber 1. The structure is such that the drainage of the snowmelt water is not affected by the snowfall and the snowmelt work can be performed smoothly. Further, by providing the snow melting passage, the snow melting water does not reach the burner and the fire is not extinguished. Further, by providing an operation box for operating a power source for a burner or a pump which constitutes the snow melting device on the back surface of the snow melting chamber lid, the occurrence of erroneous operation is prevented.

[0004]

In order to solve these problems, the present invention has the following structure. In claim 1, the snow melting chamber 1 is buried in the ground leaving an opening covered by the snow melting chamber lid 5 so that the snow melting chamber lid 5 can be opened and closed. A snow melting cylinder 26 which is long in the horizontal direction is placed in a floating state, a burner chamber 29 having a burner 12 is provided on the side of the snow melting cylinder 26, and a burner protruding from the burner chamber 29 toward the snow melting chamber 1 is provided. 1
The two hot air outlets are communicated with the inside of the snow melting tube 26, and a passage between the lower surface of the snow melting tube 26 and the bottom surface of the snow melting chamber 1 serves as a passage for the snow melting water.

In the second aspect, the operation box 20 is provided on the back surface of the snow melting chamber lid 5, and the operation switch 20 is provided on the operation box 20.

[0006]

[Operation] Next, the operation will be described. According to claim 1, the upper part of the snow melting chamber 1 constitutes a space for snow melting with the snow melting cylinder 26, and the bottom of the snow melting chamber 1 and the snow melting cylinder 26 constitute a passage for the snow melting water. As a result, the snowmelt water can be moved in the direction of the sewage or in the direction of the automatic submersible pump, and the snow that is thrown into the snowmelt chamber 1 and the upper part of the snowmelt tube 26 will interfere with the movement of the snowmelt water. Alternatively, the snow melting water does not reach the burner 12 in the burner chamber 29 to extinguish the fire.

According to the second aspect, since the operation box 20 in which the work switch 34 is arranged is provided on the back surface of the snow melting chamber lid 5 that closes the opening of the snow melting chamber 1, when the snow melting chamber lid 5 is opened. Only because the snow melting work can be started, there is no possibility that the burner 12 is ignited while the snow melting chamber lid 5 is closed and an incomplete combustion state of the burner 12 occurs due to an erroneous operation. . Further, since the operation box 20 is attached to the back side of the snow melting chamber lid 5, even when a worker falls inside the snow melting chamber 1 during the snow melting work, the work switch 34 of the operation box 20 is used. The burner 12 can be extinguished immediately by operating the, so that a safe device could be provided. Further, when the operation box is arranged at a position distant from the buried snow melting device, it is necessary to wire with a wire harness between the buried snow melting device and the operation box. Although an operation such as embedding is required, by attaching the operation box 20 to the back surface of the snow melting chamber lid 5, it is only necessary to incorporate a short wire harness into the embedded snow melting apparatus.

According to the second aspect of the invention, the work switch 3 is provided on the back surface of the snow melting chamber lid 5 which closes the opening of the snow melting chamber 1.
Since the operation box 20 in which the snow melting chamber cover 4 is arranged is provided, the snow melting work can be started only when the snow melting chamber cover 5 is opened. Therefore, the burner 12 can be opened with the snow melting chamber cover 5 closed due to an erroneous operation. There is no possibility that an incomplete combustion state of the burner 12 will occur inside the ignition.
Further, since the operation box 20 is attached to the back side of the snow melting chamber lid 5, even when a worker falls inside the snow melting chamber 1 during the snow melting work, the work switch 34 of the operation box 20 is used. The burner 12 can be extinguished immediately by operating the, so that a safe device could be obtained. Further, when the operation box is arranged at a position distant from the buried snow melting device, it is necessary to wire with a wire harness between the buried snow melting device and the operation box. Although work such as embedding is required, by attaching the operation box 20 to the back surface of the snow melting chamber lid 5, it is only necessary to incorporate a short wire harness inside the buried snow melting device.
