BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub circulation path connecting device for connecting a forced circulation line on a bathtub side to a bathtub.

[0002]

2. Description of the Related Art A forced circulation circuit of a bathtub is connected to a bathtub using a connecting device. By driving a circulation pump on the bathtub side, hot water in the bathtub is discharged from a return pipe of the circulation line. Hot water sucked by the circulation pump and sent out from the discharge side of the circulation pump through the heat exchanger is discharged into the bathtub through the outward pipe of the circulation pipeline, and forced circulation of the bathwater is performed.

[0003] When connecting the circulation line to a bathtub using a connection device, if the distance between the bathtub and the bathtub is particularly large, the outgoing line and the return line of the circulation line may be changed. There is a case where the connection is made. In this case, a problem arises in that it is not until the bath kettle is operated that the user notices an error in the pipe connection and must reconnect the pipe. This redoing of the pipe connection is an operation requiring a very complicated hand gap.

In order to eliminate such complicated work,
When the piping connection of the circulation pipe is incorrect, a connection device that switches between the suction side passage and the discharge side passage inside the connection device so that the reheating operation of the bath kettle can be performed without any trouble, for example, is realized. This is proposed in Japanese Patent Laid-Open No. 63-190865.

In this proposed device, as shown in FIG. 7, a suction passage 2 and a discharge passage 3 are provided in a connection device 1, and a return pipe 4 of a reheating circulation line is connected to the suction passage 2 side. The discharge pipe 3 is connected to an outgoing pipe 5 of a reheating line to circulate hot water in the bathtub 6. If the return pipe 4 and the outgoing pipe 5 are connected by mistake, a connecting device is used. The switching means 7 disposed inside 1 is detached and attached by changing the direction by 180 °, and the flow path is adjusted so that the return pipe 4 communicates with the suction passage 2 and the forward pipe 5 communicates with the discharge passage 3 respectively. The switching operation is performed so that the reheating operation can be normally performed by switching the flow path of the switching means 7 without performing the pipe connection again.

[0006]

However, since the proposed device has a structure in which the switching means 7 is attached to the back of the connecting device 1 by screwing, the switching means 7 is provided.
When the passage is switched by the filter, the filter cover 8 is removed, and then the front plate 10 is removed. Then, the screw 11 is loosened and the switching means 7 is removed from the cover frame 12 side to remove 180.
° Must be reinstalled with the direction changed.
When performing this work, the worker enters the narrow bathtub, and the switching means 7 is disposed in the back of the connection device 1. 11 had to be attached and detached, which made it extremely difficult to perform the work, resulting in poor work efficiency and an excessive burden on the operator.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a simple operation when a wrong connection is made between a return pipe and a forward pipe of a circulating pipe to a connecting device.
