Abstract

PROBLEM TO BE SOLVED: To simplify pipelines and improve operational convenience by installing a switching apparatus, which switches the flow of filtered bath water to a first bath water jetting outlet and a second bath water jetting outlet, above the first bath water jetting outlet and the second bath water jetting outlet. SOLUTION: A switching apparatus, which switches the flow of filtered bath water from a first bath water jetting outlet and a second bath water jetting outlet, is installed above the first bath water jetting outlet. In an upper part case 11 of the switching apparatus, a first port 13 into which filtered bath water flows and a switch valve 15 which is rotated are inscribed in a cylindrical part 16 in a rotatable manner. In a lower part case 12, a second port 14 is communicated with the second bath water jetting outlet. By carrying out switching operation of the switching valve 15, two states are made option: a state that bath water is passed through a communication hole b19 and closed in the cylindrical part 16 and a state that bath water is passed through the communication hole b19 and a communication hole a18 of the cylindrical part 16 to the first bath water jetting outlet. Moreover, bath water is simultaneously passed through both of the first and the second both water jetting outlets to be purified. Consequently, pipelines are simplified and a piping work becomes easy and operational property is improved.

Therefore, the bath water filtered by the apparatus main body 1 and flowing from the first port 13 passes through the communication hole b19 of the adjacent switching valve 15, passes through the communication hole a18 of the cylindrical portion 16, and flows through the first bath water. It flows out of the outlet 6. Some of the bath water is supplied to the second port 1 of the lower case 12.
4 and flows to the second bath outlet 7.

As described above, according to the first embodiment,
Since the switching device for the flow path of the bath water is provided above the first bath water outlet 6, the bath water is once brought to the lower switching device, and from there the first bath water blowing device is again returned. There is no need to send to the outlet 36, and piping is simplified, piping work is facilitated, and operability is improved. In addition, since the switching device is located above the water surface of the bathtub, there is no slimy operation.

Also, since the switching operation section is a switching lever, the switching operation can be performed with a lighter force than the switching knob as in the conventional example.

Further, when the bath water is caused to flow out of the first bath water outlet 6, the bath water is also caused to flow out of the second bath water outlet 7 at the same time. The bath water in the bath tub is stirred by the bath water blown out from 7 and the bath water is circulated evenly, so that the effect of purifying the bath water is improved.

Embodiment 2 FIG. Next, a second embodiment of the present invention will be described with reference to FIGS.
FIG. 7 is a top view of the switching device of the bath water circulation filtration device when the bath water flows out from the second bath water outlet 7, and FIG.
It is -VIII sectional drawing. FIG. 9 shows the first bath water outlet 6.
10 is a top view of the switching device when the bath water flows out of FIG.

In each of the figures, reference numeral 21 denotes an upper case having an annular convex portion having a first port 13 into which the bath water filtered in the apparatus main body 1 flows, and 22 denotes a first bath water outlet 6.
A lower case 23 having a convex portion as a first connection portion formed with a communication hole d25 communicating with the second port 14 as a second connection portion communicating with the second bath water outlet 7; A disc-shaped switching rotary plate 24 rotatably inserted between the upper case 21 and the lower case 22 is a communication hole c formed in the switching rotary plate 23. The upper case 21, the switching rotary plate 23, and the lower case 22 are attached such that an annular space is formed between the upper case 21 and the switching rotary plate 23 by superimposing a central portion and a peripheral edge portion, The switching rotary plate 23 is rotated along the annular space by the switching lever 8.

When the switching lever 8 is turned to the left as viewed from the front as shown in FIG. 7, the communication hole c24 of the switching rotary plate 23 becomes the second port 14 of the lower case 22 as shown in FIG.
Oppose. Therefore, the bath water filtered by the apparatus main body 1 flows through the second port 14 to the second bath water outlet 7.

When the switching lever 8 is turned to the right as viewed from the front as shown in FIG. 9, the communication hole c24 of the switching rotary plate 23 is formed as a projection formed with the communication hole d25 of the lower case 22 as shown in FIG. Facing the part. Therefore, the bath water filtered by the apparatus main body 1 flows out of the first bath water outlet 6 through the communication hole d25.

In the case where the switching device for the bath water flow path is provided above the first bath water blow-out port 6 and the switching device is formed as in the second embodiment, the above-mentioned structure is simpler, and As in the first embodiment, the piping is simplified and the operability is improved.
