Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat medium branch pipe used by being installed in a panel or the like for hot water floor heating.

[0002]

[Background Art] Floor heating is becoming more and more popular because it is an excellent heating method, but from an economical point of view, hot water type floor heating is more common than electricity bill, and usually a certain area of panels is laid in the room. A construction method is used in which the pipes are arranged side by side. In that case, it is preferred that the panel as a member is as thin as possible because it is easy to handle, and a large area is preferable because it saves piping work, but if you try to thin the panel for hot water floor heating, it will be The diameter of the pipe must be reduced, and if the area of one panel is increased, the total length of the pipe must be lengthened. It was necessary to have multiple circuits.

In this case, the hot water inlet / outlet to the panel is usually one, and the hot water is usually branched into a plurality of circuits in the panel. For that purpose, the pipes must be crossed somewhere. It was Since there is a limit to the thickness of the panel, it is difficult to cross the pipes with each other, and the branch pipe at the inlet and the branch pipe at the outlet are superposed at one place. In that case, the branch pipe is less than half the thickness of the panel, so that a branch pipe having an extremely small inner diameter was used. Therefore, as the branch pipe outlet of the branch pipe becomes farther from the inlet, the fluid resistance in the branch pipe increases remarkably.

The same applies to the branch pipe for the outlet when hot water is returned to the return port through each flow passage, and the fluid resistance in the branch pipe becomes higher as the return port is farther from the outlet. It was Topologically, the hot water from the branch pipe outlet farthest from the panel inlet must return to the branch pipe return port farthest from the outlet, and the circuit with high fluid resistance becomes more and more resistive and the flow rate increases. Was making a big difference.

[0005]

Therefore, when the fluid is branched into the branch pipes, a pressure difference is not generated between the branch pipes, it is not necessary to cross each branch pipe circuit on the way, and the inside of the panel is compact. It is to provide a branch pipe that can be loaded into.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a front cavity and a rear cavity immediately after a hot water inlet and immediately before a hot water outlet, and a plurality of branch pipe outlets are provided respectively. The branch pipe return port exits, and the containers forming the front and rear cavities are stacked one above the other to form a united branch pipe box, and the branch pipe outlet and branch pipe return port then alternate in a plane. It provides a branch tube box that projects to the inside.

In order to manufacture the above-mentioned branch tube box, first, it is composed of an outer upper half and a lower half of the box having a brim around it and a partition plate. The middle partition plate is used to form a front cavity and a rear cavity, but the surrounding area is alternately concave and convex so that short pipes for inlet and outlet and branch pipe outlet and short pipe for branch pipe return port can be fitted. There is a corrugation on the top and bottom half of the box so that the tubes can be pinched. The short pipes are combined with each other, and the collar portion is welded or fused to be integrated.

[0008]

The average height in the front and rear cavities of the branch box according to the invention is not more than half the thickness of the branch box, but the width is almost close to the width of the branch box and the fluid resistance is high. Can be significantly reduced compared to thin pipes, and branch pipe outlets and return ports are alternately provided, so a branch pipe box for thin hot water floor heating panels with multiple circuits inside without crossing the hot water circuit on the way Can be used as

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a branch pipe box for four circuits. The box upper half 1, the box lower half 2, an intermediate partition plate 3, a main inlet. Pipe 4, main outlet pipe 5,
It is composed of a branch pipe outlet 6 and a branch pipe return port 7, and they are overlapped and closely adhered to each other. When the metal member is made of metal, the brim portion 8 is welded, and when the plastic member is made, the brim portion 8 is fused or adhered. Unify.

[0010]

Second Embodiment Another embodiment is shown in FIG. 2 in which the body 9 has a main inlet pipe 4, a main outlet pipe 5, a branch pipe outlet 6 and a branch pipe return port 7.
Are arranged in the periphery and their mouths are guided to above or below the partition 10, and they are integrally manufactured by the injection molding method of plastic,
In addition, the upper lid 11 and the lower lid 12 made of the same quality plastic
Are bonded or fused to complete a branch tube box.

A typical example of the use of the branch tube box of the above invention is shown in FIG. 2 in which the circuits respectively exiting from the branch tube box return to the branch tube box without crossing.

[0012]

As described above, according to the branch pipe box of the present invention, it can be mounted on a thin hot water panel for floor heating, and the difference in fluid resistance between the branch pipe inlets and outlets compared to a normal branch pipe. Since it is possible to remarkably reduce the flow resistance and also reduce the fluid resistance itself, it is difficult to cause a difference in the hot water flow rate due to each circuit in the panel, and therefore there is an effect of making the temperature of the panel surface uniform.
