Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a bubble bath which can be easily modified from a bathtub for bathing.

[Prior art and its problems] Conventionally, a general-purpose bathtub intended only for a bath and a bubble bath intended for a bubble bath have fundamentally different incidental facilities, and if a bubble bath is desired, a bubble bath must be used. It is said that it is necessary and cannot be modified to enjoy a bubble bath in a bathtub intended only for general bathing.

As shown in FIG. 7 (Japanese Utility Model Publication No. 62-14864), the bubbly jetting metal fitting (1) is housed in a concave portion (200) formed in the tank wall, but only a general type bath is available. The target bathtub does not have such a concave portion (200), and installing a bubbly blowout metal fitting directly on the wall of the tank portion prevents it from protruding into the tank as an obstacle and taking a backrest posture, The reason why it cannot be remodeled is that there is a problem in the use of the bathtub that the backrest wall does not lean against it.

However, it goes without saying that a new purchase of a bubble bath is a real problem, and the purchase cost is high. Therefore, it is earnestly desired to modify the bubble bath to be inexpensive and not impair the usability.

[Technical problem] The technical problem of the present invention is to make it possible to enjoy a bubble bath without impairing the feeling of use in a bathtub intended only for a bath having no recessed portion on the backrest such as a backrest wall. It is in.

[Technical Means] Technical means taken in order to achieve the above-mentioned technical object are a first mounting hole for a bubble jetting part and a second mounting hole for a bath water suction part on a tank wall of a bath body. And the first mounting hole is opened to a diameter that is one size larger than the outer diameter of the bubble jetting part, and the elastic membrane plate fixed to the outer periphery of the bubble jetting part is watertight in the first mounting hole. The gist of the invention is that the bath water suction portion is fixed to the second mounting hole in a watertight manner. In addition, claim 1
It is more effective if the bubble bath jetting part and the circulation pump are connected by a circulation pipe having a flexible part, and an air intake pipe having a flexible part is connected to the bubble flow jetting part.

[Operation] The operation of the technical means of the present invention is as follows.

(Claim 1) When a bather leans against the bubble jetting part, the elastic film plate fixed to the outer circumference is watertightly fixed to the first mounting hole, so that the elastic film plate expands. Is pushed out of the body of the bathtub and does not prevent the bather from leaning against the bath wall.

(Claim 2) Further, the movement of the bubble jetting portion is absorbed by the circulation pump having the flexible portion and the air intake pipe, respectively, and does not hinder the supply of bath water and air to the bubble jetting portion.

[Advantages of the Invention] Since the present invention is configured as described above, it has the following advantages.

(Claim 1) Although the bath body is intended only for a bath without a concave portion for accommodating the bubble jetting portion on the bath wall, the bubble jetting portion is the weight of the bather even when leaning against the bath wall. Since it is moved by the stretching action of the surrounding elastic membrane plate, it can be remodeled into a so-called bubble bath in which the user can enjoy the bubble bath without obstructing the backrest posture.

(Claim 2) Moreover, since the bubble flow jetting portion and the circulation pump are connected by the circulation pipe having the flexible portion, and the bubble flow jetting portion is connected to the air intake pipe having the flexible portion, The circulating force of the bath water and the air supply mechanism are not affected by the moving force of the bubble jetting part, the deterioration of durability can be prevented, and the structure is simple and inexpensive.

In addition, the bathtub body has a first part for bubbly jets and bath water suction parts.
1, a second mounting hole is opened, and the jetting part and the suction part are attached to the first and second mounting holes respectively, and a circulation pipe having a flexible part in those parts and an air having a flexible part.

However, the circulation pipes (4) are connected to and connected to the rear chamber (6d).

The air intake pipe (5) flows from the throttle (1c) mounted on the boundary wall (8) between the front chamber (6c) and the rear chamber (6d) through the circulation pipe (4) and the rear chamber (6d). In order to mix air into the circulation flow in the mixing chamber, which is the front chamber (6c), by utilizing the suction effect of the circulation flow sent out at a higher speed, the fluid is connected to the front chamber (6c) and connected to the bath body (A). ) upper wall (a ₃₎ upper wall (a ₃ so as to open at) constituted by connecting the upper end portion of the is provided with a flexible portion (100) in whole or in part.

As is well known, the upper end of the air intake pipe (5) has an air inflow space at the opening edge and is covered with a cap.

The circulation pipe (4) is connected to a bath water suction portion (2) and a bubbly flow jetting portion (1) which will be described later, and is disposed in the circulation pump (3) at an intermediate portion, so that the entire length is obtained. The flexible portion (100) is formed over a flexible material, or at least between the circulation pump (3) and the bubble flow ejection portion (1).

The flexible portion (100) has an arbitrary structure such as cutting a desired position of the circulation pipe (4) as shown in the drawing and connecting a rubber pipe between them.

The air intake pipe (5) and the flexible part (10) of the circulation pipe (4).
(0) and (100), respectively, when the bather leans against the backrest wall (a ₂ ) and takes a bath, the elastic function of the elastic membrane plate (B) is forced to move to the outside. ) Following its movement, it expands and contracts and does not hinder the supply function of circulating flow and air flow.

Both ends of the bath water suction part (2) are opened, and a positioning protrusion (2a ') is provided in the middle of the inner peripheral surface, and a flange (2a ") is protruded in the middle of the outer peripheral surface, and a mounting nut ( 2b), insert the circulation pipe (4) from the rear opening until it contacts the positioning protrusion (2a '), and screw the mounting nut (2b) onto the outer screw (2c) formed on the outer periphery of the front opening. The nut (2b) and the collar (2a ″) are attached so that the inner circular edge of the elastic membrane plate (B) in the shape of a donut plate is watertightly attached.

This elastic membrane plate (B) is formed of a thin film of rubber, synthetic resin or the like into a donut plate-like shape as in the bubble jetting portion (1), and has an outer diameter of the bath water suction portion (2). A groove (b) for fitting is provided in an outer circular edge portion corresponding to the hole edge of the second mounting hole (12) having a diameter larger than that of the groove (b) by one hole.

By the way, since the bath water suction part (2) does not lean against the bather, the second mounting hole does not have to be watertightly mounted in the second mounting hole (12) through the elastic membrane plate (B). (12)
With a second mounting hole (12) having a diameter substantially the same as the outer diameter of the bath water suction part (2), and with the packing material at the hole edge of the second mounting hole (12) interposed, the collar part (2a ″) with mounting nut (2
It is, of course, optional to mount the second mounting hole (12) so that the edge of the second mounting hole (12) is clamped by b).

Further, the bubble jetting portion (1) and the bath water sucking portion (2) are detachable covers (9) in order to avoid direct contact between the bath portions and the same portions (1) and (2) as in the conventional case. Makeup in (10). Of course, it goes without saying that the covers (9) and (10) do not hinder the jet of bubbly flow and the suction of bath water.

In the present embodiment, the first and second mounting holes for the bubble flow jetting portion (1) and the bath water suction portion (2) opened in the bath body (A) necessary for converting the bathtub for bathing into the bubble bath. (11)
Work for attaching the above-mentioned parts (1) and (2) to (12), a circulation pipe (4) and an air intake pipe (5) having a circulation pump (3) in the middle of these parts (1) and (2) The work to connect is done by removing the apron surface (a ₄ ) of the bathtub body (A), or by opening the relatively large inspection lid provided on the apron surface (a ₄ ). After connecting the drain holes, water supply to the faucet, water supply source of the hot water supply pipe, and connection from the hot water supply source by removing the apron surface and opening the inspection lid, remove the bathtub body (A) from the installation site and After performing the work, it may be installed again, or the circulation pump (3)
If the installation space is not under the upper edge wall surface (a ₃ ) of the bath body (A), only the circulation pump (3) is provided outside the room, and the apron surface (a ₄ ) is opened to open the bubble flow ejection part. (1), a bath water suction part (2) and a circulation pipe (4) are connected, and further, an outdoor circulation pump (3) and the above-mentioned circulation through a connection port (not shown) opened on the chamber wall. You may employ | adopt the structure which connects with the connection pipe (4) with a connection pipe.

In this embodiment, the bubbling jet throat (1b) is provided with a detachable rectifying body (17).

The bubble flow jetting throat (1b) includes a spherical portion (1b ') rotatably fitted in a mounting step portion (13) provided at the rear end of the recess (6b), and the spherical portion (1b'). And a cylindrical portion (1b ″) protruding from the opening toward the opening (6a) are integrally formed,
The protruding angle of the cylinder (1b ″) can be adjusted arbitrarily.

The spherical portion (1b ') is held by annular rubber packings (14) (14) provided in the mounting step (13), and the pressing plate (15) on the entire surface of the rubber packing (14) is held. The cover (9) presses it so that it cannot be removed.

The tubular portion (1b ″) has an ejection passage (16) having a uniform jet diameter from the tip opening to the mixing chamber, and the locking portion is provided at the tip of the ejection passage (16). (16a) is provided with a groove (16b) near the rear end, and a rectifying body (17) is attached inside thereof.

The rectifying body (17) is a cylindrical outer frame part (17a) that can be inserted into the ejection flow channel (16), and the outer frame part (1) from the center of the ejection flow channel (16).
7a) rectifying plate (1
7 ') is integrally formed with the outer frame portion (17a), and a protrusion (17b) is formed on the outer periphery of the outer frame portion (17a) so as to engage with and disengageably engage with the groove (16b) by a spring action. By engaging with the concave groove (16b), the ejection passage (16) is divided into a plurality of divided passages (18) along the ejection direction of the bubbly flow.

Further, an inclined surface (19) inclined from the center of the ejection flow channel (16) toward the outer end is provided at the end of the flow regulating plate (17 ') on the upstream side of the ejection flow channel (16). In 19), an acute angle is formed from the center of the end portion toward the downstream side of the ejection flow channel (16). In addition, the sharp edge (19
a) has been formed.

Next, the operation of the rectifying body (17) will be described. The bubbly flow is equally divided into a plurality of branch flows divided by the divided flow passages (18), and the jet direction is changed by the rectifying plate (17 '). It is prepared and jets into the bathtub body (A) in a state as close to laminar flow as possible. Therefore, the pressure fluctuation when colliding with the inner surface of the jet throat (1b) of the bubbly flow and the bath water is reduced, and the impact noise is also reduced.

Further, the inclined surface (19) reduces the pressure resistance when the bubbly flow collides with the end of the flow straightening plate (17) on the upstream side of the ejection flow path (16). Therefore, the above-mentioned bubble flow is introduced into the divided flow channel (18) without lowering the ejection pressure,
It also prevents the decrease of massage effect.

Further, at this time, the elastic thin films (100) (100) absorb the vibration of the bubble jet throat (1b) and prevent the vibration from being transmitted to the tank wall (a ₂ ′).

Further, the rectifying body (17) cannot move into the ejection passage (16) due to the collision between the tip portion of the rectifying body (17) and the locking portion (16a) and the engagement between the protruding piece (17b) and the concave groove (16). Supported by. Also,
In the event of damage, remove the cover (9) and take out the throat (1b), then remove the engagement between the protruding piece (17b) and the groove (16b) with a tool such as a screwdriver, etc. ), It can be easily replaced when damaged.

In addition, the attached table shows a bathtub (E in the table) provided with the bubble flow jetting portion (1) having the bubble flow jetting throat (1b) in the present embodiment, and a bubble bathtub having a throat without a rectifying body (F in the table). 2) shows the measurement results of the noise and the ejection pressure when the bubbly flow is ejected. The noise measurement is 1m from the center of the bathtub.
The position 12 m above the floor and the jet pressure were measured at a position 1 cm away from the opening end face of the bubble jet throat (1b) in the bubble jet (1).

As a result, the bubbly flow ejection part (1) using the bubbly flow ejection throat (1b) of this embodiment has a noise level of 4 dB as compared with the conventional product.
It was found that the jet pressure of the bubbly flow was almost the same while the pressure was reduced. Therefore, the noise energy at the time of jetting the bubbly flow is reduced to about 1/2, and the jet pressure of the bubbly flow can be prevented from being reduced as much as possible by providing the rectifying body (17) in the jet flow passage (16). I was able to confirm that.

FIG. 6 shows a case where the bubble flow jetting portion (1) in which the bubble flow jetting throat (1b) is non-rotatably provided is attached to the first attachment hole (11) in a watertight manner through the elastic thin film (B). An example is shown, and (17) is a detachable rectifier similar to the above-mentioned embodiment.
