The filter (15) is provided on the wall surface of the nozzle accommodating chamber (16) as shown in FIGS. This filter (15)
Although various types can be used depending on the purpose of use, for example, molded activated carbon or non-woven fabric can be used.

Further, in the apparatus for filtering bath water according to the present invention, the nozzle housing chamber (16) has the jet nozzle (1).
The jet water flow jetted from 3) causes a negative pressure, and the negative pressure naturally causes the bath water to be sucked into the nozzle housing chamber (16) through the filter (15).

According to the present invention, by adopting such a constitution, regardless of the state of the filter (15), the nozzle accommodating chamber (16) becomes a negative pressure due to the jet water flow jetted from the jet nozzle (13). By this negative pressure, the bath water naturally goes to the filter (15), and after being filtered by the filter (15), the filtered bath water is sucked into the nozzle storage chamber (16) and then filtered. The bathtub water is a gap (17) from the nozzle storage chamber (16).
The jet water flow ejected from the jet nozzle (13) is passed through the nozzle, and the filtered bath water becomes a jet water flow and is ejected from the nozzle (6) into the bath (7). is there.

That is, the bath water filtering apparatus of the present invention is
Even if the filter (15) reaches the end of its life or is clogged, a jet jet can be emitted from the air outlet (8).

Further, as shown in FIGS. 1 to 3, a suction port (4) for sucking the bath water in the bath (1) is provided,
The bath water sucked from the suction port (4) is circulated to the jet nozzle (13), and the bath water is near the suction port (4). If a preliminary filter (2) for filtering before being sucked into the nozzle is installed, the preliminary filter (2) allows the water in the bathtub to pass through the nozzle storage chamber (1).
The filter (15) is pre-filtered before being sucked into 6) so that the bath water can be cleaned to some extent, and the bath water that has been cleaned to some extent can be passed through the filter (15). As a result, the life of the filter itself becomes long and clogging of the filter (15) is reduced.

As with the filter (15), the preliminary filter (2) can be switched to various ones according to the purpose of use, and, for example, molded activated carbon or non-woven fabric can be used.

Further, as shown in FIGS. 1 and 2, when the nozzle (6) is detachably attached to the jet nozzle (13), when the nozzle (6) is cared for, etc. In addition, since the nozzle (6) can be easily removed to achieve the purpose, and the nozzle (6) can be easily attached thereafter, as a result,
Maintenance and replacement can be easily performed.

According to the bath water filtering apparatus of the present invention, FIG.
As shown in FIG. 3 to FIG. 3, a jet nozzle (1) provided on the side wall (1) of the bathtub (7) for injecting a jet water stream is provided.
3), a nozzle accommodating chamber (16) accommodating at least the tip of the jet nozzle (13), and water that is integrated with the nozzle accommodating chamber (16) and communicates with the jet nozzle (13) inside. The nozzle (6) is provided on the wall surface of the nozzle accommodating chamber (16) and a nozzle (6) having a tip end thereof as an air outlet (8) which is provided with a possible small gap (17) and is coupled to the jet nozzle (13). The nozzle storage chamber (16) is provided with a filter (15), and the nozzle storage chamber (16) has a negative pressure due to the jet water flow jetted from the jet nozzle (13). Due to this negative pressure, the bath water naturally has the nozzle storage chamber (16). Since it is sucked into the inside of the nozzle through the filter (15), regardless of the state of the filter (15), it is jetted by the jet water jet from the jet nozzle (13). The delivery chamber (16) has a negative pressure, and the negative pressure naturally causes the bath water to flow toward the filter (15). After being filtered by the filter (15), the filtered bath water is filtered into the nozzle storage chamber (16). ),
And this filtered bath water is the nozzle storage chamber (16).
From the nozzle (6) into the bath (7) from the nozzle (6) through the gap (17) from the nozzle (6), which is urged by the jet water jet injected from the jet nozzle (13). It is what is jetted.

That is, the bath water filtering device of the present invention is
Even if the filter (15) reaches the end of its life or is clogged, a jet jet can be emitted from the air outlet (8).

[0026]

According to the apparatus for filtering bath water according to the first aspect of the present invention, regardless of the state of the filter (15), the jet water flow jetted from the jet nozzle (13) causes the nozzle housing chamber (16) to move. A negative pressure is generated, and the negative pressure naturally causes the bath water to flow toward the filter (15), and after being filtered by the filter (15), the filtered bath water is sucked into the nozzle storage chamber (16), Then, the filtered bath water passes through the gap (17) from the nozzle storage chamber (16) and is energized by the jet water flow jetted from the jet nozzle (13), and the filtered bath water is jetted. The water flow is sprayed from the nozzle (6) into the bath (7).

That is, the present invention provides a filter (15).
The jet jet can be emitted from the air outlet (8) even when the exhaust gas has reached the end of its life or is clogged.

According to the bath water filtering device of the second aspect of the present invention, in addition to the case of the first aspect, the preliminary filter (2) allows the bath water to flow into the nozzle accommodating chamber (16).
The bath water can be pre-filtered before being sucked into the bath to clean the bath water to some extent, and the bath water that has been cleaned to some extent can be passed through the filter (15). The life is extended and clogging of the filter (15) is reduced.

According to the bath water filtering apparatus of the third aspect of the present invention, in addition to the case of the first aspect or the second aspect, the nozzle (6) can be easily cleaned when the nozzle (6) is maintained. ) Can be removed to achieve the purpose and the nozzle (6) can be easily attached thereafter, resulting in easy maintenance and replacement.
