BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a bubble generating bath according to the present invention. FIG.
FIG. 2 is a cross-sectional view illustrating a suction portion of hot water in the bubble generating bathtub of the present invention.

[0013] For example in the example of FIG. 1, the suction portion of the bathwater in the tub wall (1) (2) is provided, the circulation pump (3) is attached directly to the suction unit (2) I have. The circulation pump (3) has a packing (5) interposed between the casing (4) and the wall surface (1) of the bathtub,
It is fixed by a casing fixing nut (6).
The circulation pump (3) includes a back casing (7).
It is provided, inside this, each of the outer water passage portion (8), formed by fractionating ward energization section (9) so as to ensure the insulating property of the energizing portion (9).

A rotor (10) in which a pump impeller and a motor rotor are integrated is fixed to the water passage section (8) via a washer (12) on a rotating shaft (11). The rotating shaft (11) is rotatably fixed to bearings (14) provided on the pump lid (13) and the back casing (7) opposed thereto. This enables rotation of the rotor (10) about the rotation axis (11). The pump lid (13) is fixed to the casing (4) by a fixing nut (15).

The water passage (8) has a yoke (1).
6) and a magnet (17) are also provided. On the other hand, a stator (18) is provided in the energizing section (9). The circulation pump (3) is connected to a water supply pipe (19) connected to an injection port for injecting a bubble-mixed jet in the casing (4) on the water flow section (8) side. .

A filter (20) made of a nonwoven fabric is provided on the front surface of the suction section (2). FIG. 2 is a front view of the filtration filter. For example, as shown in FIG. 2, the filtration filter (20)
It is formed from a nonwoven fabric, the diameter of the small first opening (2
Many 1) are formed. Bath water in the bathtub is supplied to the first opening (2) when the circulation pump (3) illustrated in FIG.
A relatively small substance such as dirt in the bath water is sucked through 1) and removed by the filter (20).

The filter (20) includes a first filter .
A second opening (22) having a diameter larger than that of the opening (21) may be formed coaxially. This second opening (22)
Is the first opening (21) of the filtration filter (20)
This is provided as a bypass for preventing the occurrence of clogging and a decrease in the flow rate of the jet flow containing bubbles. Second opening (22) as such a bypass
, The flow rate of the jet in the bubble generating bath is kept constant. In addition, there is no fear that the circulation pump (3) runs idle due to clogging of the filtration filter (20). The dirt and the like in the bath water sucked from the second opening (22) is only a part when viewed from the entire bath water, and does not affect the operation of the circulation pump (3) at all.

In the example shown in FIG. 1, a suction cover (23) is mounted on the front surface of the filter (20). The filtration filter (20) is attached to the back surface of the suction cover (23) by being sandwiched by a filtration filter mounting nut (24). Therefore, the filtration filter (20) is connected to the suction section (2).
When mounting the filter, the filtration filter (20) is inserted into the back of the suction cover (23), and the filtration filter mounting nut (24) is screwed into the suction cover (23) so that the filtration filter (20) is pinched. And fixed to the suction cover (23). Next, in this state, the suction cover (23) is attached to the suction part (2). The attachment of the filtration filter (20) to the suction part (2) is simplified. In cleaning, the filtration filter (20) can be easily removed by removing the suction cover (23).

Of course, the filter (20) may be not a non-woven fabric but an appropriate woven fabric. FIG. 3 <a><
b><c> are a front view, an AA cross-sectional view, and a bottom view illustrating a suction cover, respectively. For example, in FIG.
As shown in a><b><c>, the suction cover (23) has a suction port (25) formed on the lower surface thereof. Thus, by providing the suction port (25) only on the lower surface of the suction cover (23) provided as a cover body of the suction part (2), for example , the wall surface (1) of the bathtub in the upper part near the suction part (2) is formed. ) Is provided with an injection port, and even if the jet injected from the injection port hits the back, soles, etc. of the bather, bubbles can be effectively prevented from being sucked into the circulation pump (3). Bubbles are in the inlet (25)
As a result, the occurrence of air clogging that may occur in the circulation pump (3) is prevented, and the problem of the failure of the circulation pump (3) can be solved. Operational stability of the circulation pump (3) is ensured.

The suction cover (23) is inclined forward from the upper part to the suction port (25) on the lower surface. By doing so, the opening area of the suction port (25) provided on the lower surface of the suction cover (23) is sufficiently ensured, and the suction of bath water is ensured. The suction port (25) is not blocked by the bather during bathing,
The circulation pump (3) illustrated in FIG. 1 does not run idle. At the same time, the protrusion of the suction cover (23) into the bathtub can be minimized. The suction cover (23) does not hinder bathing, and the appearance is good.

In this example, the suction port (25)
A metal net (26) as a net is attached by welding or the like. The wire mesh (26) is arranged closer to the bathtub in the flow of the bath water than the above-mentioned filter (20). The hole is in rather than come large <br/> than the filtration filter (20). In operation of the circulating pump (3) it is captured by relatively large gold network such as hair and dust in the bathwater (26). Such as hair, and dust is prevented from being sucked into the suction unit (2), clogging of the filtration filter (20) is effectively suppression. Furthermore, such hair or dust is also prevented from being caught in the rotor (10) of the circulation pump (3), a failure of the circulation pump (3) is prevented. In addition, the net body may be a woven cloth or the like having a large opening degree, instead of the wire mesh (26) as described above. Oite Such bubble generation bath can be filtered by the bathwater circulating during operation of the bubble generating bath, and sequentially passes through the wire mesh (26) and filtration filter (20). Hair in the bath water, is relatively large, such as dust, or not a gold network (26)
, Then small things such as dirt are removed by a filtration filter (20). As in the conventional filtering function with the bubble generating bath, it is not necessary to provide a filtration tank into the circulation pump (3), it is possible to realize a filtering function in a simple, structure becomes simple. Therefore, the filtering function is realized at low cost.
