Description

[Detailed description of the invention] <Industrial field of application> The present invention has an air blowing function that blows air bubbles into the water in the bathtub, and has a configuration in which an air supply unit is placed immediately outside the side wall of the bathtub. Regarding the unit bus.

<Prior art> The air blow function generates a large number of bubbles in the water in the bathtub by blowing the air under pressure from the air pump in the air supply unit into the water in the bathtub, and these bubbles blow the entire body of the bather. It envelops the bather, giving the bather a comfortable bathing feeling and a pine surge effect.

The air blow mechanism consists of an air supply unit including an air pump, an air blow nozzle provided on the bottom wall of the bathtub, and an air supply pipe connecting the air pump and the air blow nozzle. If the air pump is installed outside the bathroom, the air pipe will have to pass through the wall or ceiling of the unit room, and there is a risk that the waterproofness and airtightness, which are the characteristics of the unit bath, will be impaired.

Therefore, it has been proposed to install the air supply unit inside the bathroom and also route the air supply pipe inside the bathroom to ensure waterproofness and airtightness. Hereinafter, such an example will be explained with reference to FIG. 6 (see, for example, Japanese Utility Model Publication No. 7117/1983).

An air blow nozzle 4 is provided on the bottom wall 2a of the bathtub 2, while an air supply unit 6 is installed in a portion called an apron immediately outside the side wall 2b of the bathtub 2.
An air pump 8 and an air blow nozzle 4 in the air supply unit 6 are connected via an air supply pipe 10. Air pump 8 pumps water surface 12a of bathtub water 12
Since the bathtub water 12 is located lower than the air pump 8, a head pressure corresponding to the head difference will be generated between the bathtub water 12 and the air pump 8.
2 to prevent it from flowing back into the air pump 8.
A part of the air supply pipe 10 is once raised to a position higher than the upper edge 2c of the bathtub to form a trap part 10a.

Then, the air pump 8 and the trap section 10a
An air supply unit 6 consisting of an air supply pipe 10 including
In order to cover up the air supply unit 6, an air supply unit covering part 14 is formed above the air supply unit 6, which extends from the upper edge 2c of the bathtub and bulges above the upper edge 2c of the bathtub.

<Problem to be solved by the invention> In order to prevent backflow due to water head pressure, a trap section 10a is formed on the air supply pipe 10, but the air supply unit covering section 14 is configured to cover up the existence of this trap section 10a. As a result, this bulges out above the upper edge 2c of the bathtub. The presence of the air supply unit covering portion 14 that bulges out in this manner is an eyesore for bathers and has a poor design feel.

The present invention was devised in view of these circumstances, and because the air supply unit covering part that covers the entire air supply unit has an air supply pipe trap part that is necessary to prevent backflow. To solve the problem of a bathtub bulging above the upper edge and to improve the design feeling of a unit bath.

<Means for solving the problem> In order to achieve the above purpose, the present invention
An air supply unit disposed immediately outside the side wall of the bathtub, an air blow nozzle provided on the bottom wall of the bathtub, and an air pump in the air supply unit connected to the air blow nozzle, a part of which connects to the upper edge of the bathtub. an air supply pipe configured as a trap section for preventing backflow that stands up above the bathtub; and an air supply unit covering section that extends integrally from the upper edge of the bathtub and covers the air supply unit from above. The unit bath with air blow has the following configuration.

In the first unit bath with air blow according to the present invention, the air supply unit covering part is configured to have almost the same height as the upper edge of the bathtub, and the air supply pipe trap part is arranged in an inverted U shape to the air supply unit covering part.
It is characterized by its penetrating shape.

In the second unit bath with air blowing according to the present invention, the air supply unit covering part is configured to have almost the same height as the upper edge of the bathtub, and the legs of the shelf unit along the bathroom wall are arranged at the upper edge of the bathtub or the upper edge of the bathtub. It is characterized in that the air supply pipe trap section is mounted and supported on the air supply unit covering part and embedded in the shelf unit through the legs of the shelf unit.

<Function> According to the first unit bath with air blow,
Since the air supply unit covering part is configured at almost the same height as the upper edge of the bathtub, it is more comfortable than the conventional example in which the air supply unit covering part bulges upward relative to the upper edge of the bathtub. The entire bathtub looks sleeker, and the design of the unit bath is improved.

Since the air supply unit covering part is configured to have almost the same height as the upper edge of the bathtub, the air pipe trap part penetrates and protrudes upward from the air supply unit covering part. The inverted U-shaped part can be used as a handrail or towel rack, and the protruding air pipe trap part itself emphasizes its functional beauty.
Its protrusion does not impair the sense of design; on the contrary, its functional beauty improves the sense of design.

According to the second unit bath with air blow,
As with the first unit bath, the design of the unit bath is improved by making the air supply unit covering part almost the same height as the top edge of the bathtub, and the air supply unit covering part is made almost the same height as the top edge of the bathtub. The air pipe trap part, which protrudes above the upper edge of the bathtub or the covering part of the air supply unit due to its height, is embedded in the shelf unit through the legs of the shelf unit. The air pipe trap part does not spoil the design, and also serves as reinforcement for the shelf unit.

<Example> Hereinafter, an example of the present invention will be described in detail based on the drawings.

<Effects of the Invention> As explained above, the present invention provides the following effects.

According to the first unit bath with air blow,
Since the air supply unit covering part is configured to have almost the same height as the upper edge of the bathtub to eliminate its bulge, the design of the unit bath can be improved.
Moreover, the air pipe trap can also be used as an inverted U-shaped handrail, towel rack, etc.
Rather than avoiding the deterioration in design due to the protruding air pipe trap portion, it is possible to improve the design.

According to the second unit bath with air blow,
At the same time as eliminating the bulge in the air supply unit covering section, we also eliminate the exposure of the air supply pipe trap section by embedding the air supply pipe trap section within the shelf unit, which improves the design of the unit bath. At the same time, the shelf unit can be reinforced by the air pipe trap section.
