Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bath adapter, and more particularly to a bath adapter used for supplying hot water into a bathtub from a forced circulation bath water heater.

[0002]

[Problems to be solved by conventional techniques and devices]

 The forced circulation bath water heater supplies hot water to the bathtub from the outward pipe that composes the circulating hot water supply line, and returns the hot water in the bathtub to the water heater from the return pipe that composes the circulation supply line. It is configured to circulate hot water between the bath and the bath.

Therefore, the bath adapter for the forced circulation bath water heater has a hot water outlet connected to the outward pipe and a water inlet connected to the return pipe.

[0004] However, when piping is installed at the time of installation of the forced circulation type bath water heater, when the outgoing pipe and the return pipe are connected to the bath adapter separated from the water heater, the outlet pipe to which the outgoing pipe should be connected is mistaken. In some cases, the return pipe may be connected to the communicating pipe connection, and the forward pipe may be connected (mis-connected) to the pipe connection that communicates with the water intake to which the return pipe should be connected.

In such a case, for example, in the conventional bath adapter as shown in FIG. 6, a plurality of (for example, three) switching valve retainer screws 52 for pressing the switching valve 51 are removed, and a switching valve retaining screw 53. Remove the (one), rotate the switching valve 51 by 180 ° C, and tighten the switching valve retainer screw 52 and the switching valve stopper screw 53 at that position to set the forward pipe and the return pipe to the predetermined output. It is configured to communicate with the sprue and water intake.

In other conventional bath adapters as well, similar to the above-mentioned conventional bath adapters, by removing the switching valve holding screw or the switching valve locking screw and rotating the switching valve, the forward pipe and the return pipe are set to the predetermined pipes. It is configured to communicate with the outlet and the water intake.

Therefore, for example, if the bath adapter as shown in FIG. 6 is erroneously connected, the switching valve retainer set screws 52 and the switching valve set screws 53 at a plurality of locations are removed, and the switching valve 51 is rotated by 180 ° C. It is necessary to tighten the switch valve retainer screw 52 and the switch valve retainer screw 53 by tightening it, but this work must be done in a narrow bathtub, not only the workability is poor, but also removed. In some cases, the screws may fall into the water drainage holes in the bathtub, which increases the time required for construction.

The present invention solves the above-mentioned problems, and can easily switch to the normal connection even if an incorrect connection is made between the outgoing pipe and the return pipe and the hot water outlet and the water intake port. Intended to provide a bath adapter.
