Abstract

PROBLEM TO BE SOLVED: To provide a hot water blowout/suction switch gear for a bathtub which functions as blowoff apparatus when connected to a hot water supply pipe or as suction apparatus when connected to a hot water return pipe in the connection of the hot water supply pipe or the hot water return pipe. SOLUTION: An inner cylinder 65 is so arranged to be internally fitted slidably into a cylindrical outflow or inflow passage 22 or 24 while a blowoff port 63 and a suction port 64 are internally provided on a side 62 thereof with one end 61 thereof closed. When the inner cylinder 65 is fitted into the outflow or inflow passage 22 or 24, the one end 61 closed thereof 65 shuts the outflow or inflow passage 22 or 24 while the suction port 64 of the inner cylinder 65 is made to overlap a suction port 27 of the outflow or inflow path 22 or 24. When the inner cylinder 65 sticks out of the outflow or inflow passage 22 or 24, the blowoff port of the inner cylinder 65 is opened outside the outflow or inflow passage 22 or 24.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub hot-air / suction switching device and a bathtub spout for use in circulating bath water between a bathtub and a circulation heating pot.

[0002]

2. Description of the Related Art Conventionally, hot tub hot water heated by a circulating heating kettle is supplied to a bathtub through a hot water supply pipe through a hot water supply port of a bathtub spout fitting attached to the bathtub. As hot water, from the hot water outlet of the bathtub spout fitting,
It was returned to the circulating heating kettle via a hot water pipe, and the circulation process of the bath tub to be heated again was repeated. However, the conventional bathtub spout is provided with a hot water outlet through which hot water heated by the circulating heating kettle flows out of the bathtub so as to face the side surface of the net cover, and a return spout through which cold water that has become cold in the bathtub flows. Was provided so as to face the front of the net cover,
If the two pipes (hot water supply pipe and return hot water pipe) connecting the circulating heating kettle and the bathtub spout were connected by mistake, there was a risk that hot water would flow out of the front of the mesh cover into the bathtub. Further, in order to eliminate this danger, a water discharge chamber and a water absorption chamber are formed in the bathtub spout, and a number of check valves are provided in a communication part connecting the water discharge chamber and the water absorption chamber to the two pipes. Regardless of the connection between the circulation fitting and the two pipes, the hot water is always sent to the spout chamber and sent out from the spout provided in the spout chamber to the bathtub, so that the A bathtub spout fitting without wire mesh strainer appeared,
Since this bathtub spout has many check valves,
It has a disadvantage that the structure is complicated and expensive, and a failure often occurs due to deterioration and wear of the valve.

[0003]

According to the present invention, when connecting a hot water supply pipe and a return hot water pipe, if it is connected to the hot water supply pipe, it becomes a blowing device, and if it is connected to the return hot water pipe, it becomes a suction device. An object of the present invention is to provide a bathtub hot-air suction switching device which has a long service life and does not cause a failure.

Further, the present invention provides a bathtub spout fitting in which no mistake in connection occurs when connecting a hot water supply pipe and a return hot water pipe.
