Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a bathtub equipped with a device for spouting air bubbles into the bathtub.

(Prior art) Conventionally, devices for ejecting air bubbles into a bathtub include:
For example, as described in Japanese Patent Application Laid-Open No. 56-121557, a spout portion and a suction port are provided at the upper and lower portions of one side wall of the bathtub, respectively, and these are connected through piping to form a circulation path. It was common to have a bathtub equipped with a bubble blowing device, in which one end of an air suction pipe was connected to the bathtub, and a circulation pump was installed in the circulation path.

(Problem to be solved by the invention) However, in the case of the above-mentioned conventional bathtub with bubble ejecting device, the circulation pump is installed at a location away from the bathtub, but in reality, the circulation path 2 and piping 6 are As shown in FIG. 1, they are rarely arranged horizontally. The reason for this is that if the piping is installed almost horizontally like this, the hot water in circulation route 2 will not be returned to the bathtub when the circulation pump stops, and in winter, this accumulated water will cause freeze damage. be. Therefore, it is necessary to set the piping slope so that the pump is higher than the suction port.Also, when such long piping is used, it is easy to bend and create air pockets, making it difficult to start the circulation pump. The drawback was that it made my sexuality worse.

To compensate for these shortcomings, the methods described in, for example, Japanese Patent Application Laid-open No. 52-98383 and Japanese Utility Model Application No. 62-45025 have been proposed. The former of these conventional technologies is a bathtub consisting of an inner tank and an outer tank, and has a so-called outer tank where the rim of the bathtub is folded downward to the same height as the bottom of the inner tank on the outside. The article relates to a bathtub in which a jet pump and a motor are housed in a triangular space between the inner tank slanted wall and an outer tank. In addition, a bottom plate part must be formed between the inner tank and the outer tank, and the jet pump, etc. must be housed in the bottom plate part, and it is necessary to store the jet pump and motor at the same time when forming the bathtub. Assembly was complicated.

Also, the latter technology (Utility Model Application Publication No. 1983-45025)
In this method, a horizontal member parallel to the legs of the bathtub body is fixed, and a support base made of several angle members is protruded from the horizontal member, and forced circulation means for the bath is placed on this support base. There was a problem in that when the bathtub was lifted, the support base was easily bent, and the forced circulation pipe between the bathtub and the circulation pump was easily bent and damaged.

(Means for Solving the Problems) The bathtub with a bubble blowing device of the present invention was made to solve the above-mentioned drawbacks of the conventional products. A mounting plate is mounted to the side wall via the spout member and the suction port member, a power unit consisting of a circulation pump and a motor is mounted to the mounting plate, and the A bathtub with a bubble ejecting device includes a circulation pump of a power unit, a spout member, and an inlet member connected by a connecting pipe to form a circulation path.

(Function) In this invention, the bubble ejecting device is attached to the back of the side wall of the bathtub, so the piping can be short, it does not bend and cause air pockets, and there is no need to set the piping slope. be.

(Example) Fig. 1 shows a case where an embodiment of the present invention is applied to a bathtub with a washing area, and is a cross-sectional view when looking at the bathtub side. The rising wall 1 is bent outward from its top edge and extends horizontally, and a bathtub 3 can fit into the extended surface 2. A notch 4 of the same size is bored, and the notch 4
A bathtub 3 having a power unit 6 consisting of a circulation pump and a motor attached to the outside of a side wall 5 of the bathtub is fitted with its upper edge 7 exposed upward.

The bubble ejecting device in the present invention includes the power section 6
In addition, there is a spout member 8 provided at the top of the side wall 5 of the bathtub 3, and a suction port member 9 also provided at the bottom.
, connecting pipes 11 , 11 which connect these to form a circulation path 10 , and an air suction pipe 12 whose one end is connected to the ejection port member 8 .

The spout member 8 and the suction port member 9 are attached to the upper and lower parts of the side wall 5 of the bathtub 3, respectively, as shown in FIGS. 2 and 4. As shown in the figure, the mouth member main body 13, which has a circulation port 14 penetrating therein which forms a part of the circulation path, is inserted from the bathtub side into the mounting hole via the gasket 15, and the mouth member main body 13 A female screw 17 that can be screwed together with a male screw 16 screwed around the side wall 5 is fastened to the side wall 5 with a tightening nut 18 screwed thereon.
Then, a stud head 19 is screwed into the opening of the mouth member main body 13 on the bathtub 3 side. Next, the mouth member body 1
3 into the through hole 21 of the mounting plate 20, and further securely attach the mounting plate 20 to the mouth member main body 13 with a tightening nut 22. The spout member main body 13 has substantially the same structure in both the spout member 8 and the suction port member 9, and only in the case of the spout member 8, the rivet head 19
It has a ball 23 whose ejection direction is variable, and an air inlet 26 to which the air suction pipe 12 is connected.

When the mounting plate 20 is integrally attached to the side wall 5 of the bathtub 3 via the spout member 8 and the suction port member 9 as described above, the mounting plate 20 has the following features as shown in FIGS. As shown in FIG. 4, a support plate 25 is attached to the outer horizontal direction of the mounting plate 20, and the power unit 6 is installed on the support plate 25.

Further, in the examples shown in FIGS. 3 and 4, there is one spout member 8, but as shown in FIG. 5, two spout members 8 may be arranged side by side in the horizontal direction. good.

The bubble ejecting device configured as described above sucks hot water from the bathtub 3 through the suction port member 9 provided on the side wall 5 of the bathtub 3, and sucks hot water from the bathtub 3 through the suction port 26 opened in the wall board of the bathroom. It has a function of being ejected from the ejection port member 8 together with the sucked air.

(Effect of the invention) According to the invention, the spout member and the suction port member are respectively attached to one side wall of the bathtub, and the mounting plate is attached to the side wall via the spout member and the suction port member. A power unit consisting of a circulation pump and a motor was attached to the mounting plate, and the circulation pump was connected to the spout member and the suction port member by a connecting pipe to form a circulation path. It is possible to reduce the cost of piping parts and piping work, and
Since piping resistance is low, low power is required and it is efficient, and the piping does not bend causing air pockets or water to accumulate in the piping, so there is no freezing damage or startup failure of the power part. It has many advantages such as

Further, the power section can be easily attached by being integrally and firmly attached to the side wall of the bathtub. Therefore, when installing or removing a bathtub in a bathtub type bathroom unit with a washing area, the construction work of installing or removing the bathtub with the power unit attached becomes easy.

Incidentally, in the case where the support plate is provided laterally outward from the mounting plate as in the above embodiment, the power unit can be installed on the support plate, so construction is easier.
