Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to a device for rapidly thawing ice in water pipes, particularly in the rising portions of water pipes near faucets, during the winter.

(Prior Art) Until now, there is a known method for melting ice by pouring boiling water into an attached pipe that is brought into skin contact with the rising part of a water pipe.
45−33778 etc.). In addition, the known techniques described in the above-mentioned publications include making the attached pipe crescent-shaped in cross-section to increase the heat-receiving area, and creating a constricted part at the lower end of the attached pipe to create flow resistance of hot water. belongs to

(Problems that the invention aims to solve) However, with these conventional devices, it is necessary to inject a considerable amount of hot water, and it takes some time for heat exchange because it relies on heat conduction through attached pipes. In short,
The reality was that there was no hope of immediate thawing. Furthermore, if the attached pipe has a crescent-shaped cross section in order to expand the heat receiving area, there is a drawback that it cannot meet the needs for bent construction depending on the construction site.

In view of the current situation with conventional equipment, the present invention aims to provide instant results and save as much as possible in the amount of hot water injected by directly irradiating and flowing hot water onto the frozen part, and by working together with heat conduction through attached pipes. It aims to achieve the goal of thawing the ice.

Another object of the present invention is to provide an ice-melting device in which the attached pipe can be bent freely to suit the site.

[Structure of the idea]

(Example) To explain the following using the example shown in the drawings, 1 is a water pipe that rises vertically from the ground through a bent part 2, and its upper end is bent horizontally to form a water pipe at its tip. Faucet 3 is installed.

A heat conductive pipe body 4 made of highly flexible material such as copper is fixed in close contact with one side of the water pipe 1 (that is, in contact with the skin). A plurality of hot water injection holes 5 are provided in the part near the faucet 3, and the upper end of the pipe body 4 is a hot water inlet 6 with a relatively large diameter, and the lower end of the pipe body 4 facing underground is constricted into an opening. Section 7 has been applied.

Furthermore, most of the water pipe 1 and the heat conductive pipe body 4 which is in skin contact with the water pipe 1 are made of a material with a suitable thickness, such as styrofoam, which is highly insulating, and have a vertical hole 8a in the center, as shown in FIG. It is wrapped in a holding type heat insulating material 8 having a slit 8b at one end, and the vertical hole 8
It is constructed by forming two substantially triangular hot water flowing down spaces 9 surrounded by the inner wall a and the outer walls of the water pipe 1 and the heat conduction pipe body 4.

Note that 10 in the drawing is a cap that closes the hot water inlet 6.

(Functions and Effects) Now, when it freezes in winter, the cap 10 is removed and hot water is poured into the hot water inlet 6. Then, a part of the hot water that has flowed into the heat conduction pipe body 4 is transferred to the water pipe 1 near the faucet 3 through the plurality of hot water injection holes 5 provided along the way.
The hot water is sprayed intensively to the water pipe 1, immediately thawing the frozen water in the water pipe 1, and causes the hot water to descend along the two hot water flow spaces 9, thereby exerting a direct heat exchange effect on other parts of the water pipe 1. prompt. In addition to this, the remainder of the hot water that has flowed into the pipe body 4 descends while gradually exchanging heat with the water pipe 1 that comes into skin contact with it, and is discharged underground from the bottom end of the pipe body. Since a constriction part 7 is provided at the lower end of the boiler 4, flow resistance is created and the residence time of the hot water is extended and maintained.

In other words, in the present invention, the direct and concentrated injection of hot water from the hot water injection hole 5 and the direct heat exchange effect in the flowing process, and the heat exchange effect due to heat conduction of the tube body 4 are extremely effective. This makes it possible to melt ice quickly and efficiently. Therefore, the amount of hot water injected is extremely small, which helps save fuel.

In addition, the heat conduction tube 4 is an ordinary circular tube made of a copper tube or the like which has flexibility and whose cross section is not particularly deformed, so that it can be bent freely according to the site, as shown in Fig. 5, for example. There are advantages.
