DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub, and more particularly, to a bathtub with a bubble bath function in which air is taken in from the outside and the air is blown into the bathtub together with hot water to form bubbles. .

[0002]

2. Description of the Related Art Conventionally, in a bathtub of this type, as shown in FIG. 8, a switch a for operating a drain plug is provided on an upper surface of a flange portion b and an air intake portion c for generating bubbles.
(See, for example, Japanese Utility Model Publication No. Sho 61-30682 and Japanese Patent Application Laid-Open No. Hei 9-47372).

[0003]

By the way, this type of bathtub has a bubble bath function, so that the number of parts increases and the price is inevitably higher than that of a normal bathtub. It is desirable that the number of parts be as small as possible so that the number of parts can be reduced.

However, as described above, in the conventional product, the operation switch of the drain cock and the intake portion of the air for generating bubbles are separately attached to the flange portion. Therefore, in the case of the conventional product, it was necessary to attach each of the above-mentioned parts to the flange portion. Therefore, according to the conventional product, the number of components increases accordingly, time and labor are required for assembling, and the manufacturing cost is high. Rather, there is a problem that the upper surface of the flange portion is cluttered and the design is impaired.

Conventionally, in the case of this type of bathtub, the intake portion of the air for generating bubbles is usually formed higher than the operation switch portion of the drain plug so that hot water does not enter through the intake portion. Therefore, when a conventional product is used, there has been a problem that the lid of the bathtub must be a dedicated product in which a position corresponding to the above-mentioned intake portion is cut out.

[0006] Further, since this kind of bathtub is intended to provide a bather with a comfortable bath life, the air suction sound which is likely to cause discomfort to the bather is reduced by a special component or mechanism such as a silencer. It is desirable to be formed so as to be able to be wiped out by a low-cost and simple mechanism without accompanying.

However, as described above, the conventional product has a structure in which the air suction portion is provided in the flange portion and the air is sucked from the upper surface of the flange portion. There was a problem that it was easy to give discomfort. Further, in the conventional product, a muffler or the like is usually provided in the pipeline in order to suppress the intake noise. Therefore, in the conventional product, it is unavoidable that the cost increases accordingly.

[0008] The present invention has been proposed in view of such problems of conventional products. Therefore, the technical problem of the present invention is to increase the cost and improve the design of the flange portion by independently providing an air intake portion in a bathtub with a bubble bath function provided with an operation switch portion of a drain plug on the upper surface of the flange portion. It is an object of the present invention to provide a bathtub with a bubble bath function formed so as to be able to eliminate the adverse effects of reduced properties and the exclusive use of a lid.

Another technical object of the present invention is to provide a bathtub with a bubble bath function provided with a bubble generating air intake section on the upper surface of a flange portion, which can eliminate air intake noise with a low-cost mechanism and provide comfortable operation. An object of the present invention is to provide a bathtub with a bubble bath function formed so as to be able to take a bath.

[0010]

The present invention employs the following technical means in order to solve the above-mentioned problems.

That is, as shown in FIG. 1, the present invention relates to a bathtub with a bubble bath function provided with a bubble generating air intake section 2 on the upper surface of a flange section 1, wherein the intake section 2 comprises: The invention is characterized in that it is incorporated in a drain cock operation switch unit 3 provided on the upper surface of the flange unit 1 (claim 1).

Here, the capturing unit 2 is operated by the operation switch unit 3.
Embedded in the camera means that the operation switch unit 3 has a function of taking in air for generating bubbles. Specifically, as shown in FIG. 1, a bush 3b that forms an air flow path as the intake section 2 around the push button 3a of the operation switch section 3 and includes the push button 3a
This is achieved by forming an air discharge end 3d on the peripheral wall of the switch main body 3c to which is screwed, and connecting the discharge end 3d and the flow pipe 5 for guiding the air to the jet nozzle 6 in a communicating manner.

In this case, the air flow pipe 5 may be connected to the side end of the pipe joint 14 in a communicating manner, for example, as shown in FIG. In this case, the pipe joint 14 is connected to an appropriate position of the protective tube 9 of the transmission member 8 that transmits the operation of the operation switch unit 3 to the drain plug 4. When the air circulation pipe 5 is connected in this way, it is preferable to pipe the middle of the path near the flange 1 as shown in the figure to prevent the backflow of hot water in the bathtub. Also fitting 1
4 is preferably provided with a through portion 14b communicating with the air flow path 14a so that the bath water can be drained from the protection tube 9 even if the bath water flows backward.

The bathtub of the present invention is, as shown in FIG.
A tub with a bubble bath function provided with a bubble generation air intake portion 2 on the upper surface of the flange portion 1, wherein the intake portion 2 opens an air inlet 10 below the flange portion 1. (Claim 2).

In this case, the bubble generating air intake section 2
Is a mounting hole 1a of the flange 1 as shown in FIG.
A cylindrical main body 2a whose periphery is attached in a watertight manner;
A lid 2c which is screwed to the short cylindrical screwing portion 2b of the main body 2a to close the opening surface of the main body 2a, and which is located inside the screwing portion 2b of the main body 2a. A cylinder 2d is formed, and an air inlet 10 is formed in a flange-shaped connection surface 2e that connects the inner cylinder 2d and the screw portion 2b. The air taken in from the air inlet 10 is jet nozzled. 6 and the air outflow end 2f of the inner cylinder 2d
Are preferably connected in a communication manner (claim 3).

In this case, there is an advantage that the lid 2c can be removed from the upper surface side of the flange portion 1 and inspection of the inlet 10 such as clogging can be easily performed.

In the case of the present invention, the air inlet 10 is
As shown in FIG. 5, it is preferable that the air outlet end 2f of the inner cylinder 2d is formed on the outer peripheral wall of the threaded portion 2b and is branched (claim 4).

That is, in the case of the present invention, the air inlet 10
In short, as long as it is open below the flange part 1, the formation position, shape, number, etc. are arbitrary. The air inlet 10 may be formed so that its diameter and numerical aperture can be changed by, for example, rotating the lid 2c. Further, the intake section 2 is preferably formed so that the inner cylinder 2d is higher than the upper surface of the flange section 1 so that hot water in the bathtub does not flow backward beyond the upper end of the inner cylinder 2d when the bath is full. When the intake section 2 is formed as shown in FIG. 5, air can be sucked into the distribution pipes 5 of a plurality of systems from the back side of the bathtub and distributed, and a muffler for removing suction noise is provided in each flow pipe 5. It is not necessary to provide each
There is an advantage.
