Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an air intake structure of an air blower device in a unit bath for inhaling air from the outside of a wall panel and ejecting bubbles into a bath.

<Prior Art> Some unit baths incorporate an air blower device for ejecting bubbles into a bath.

FIG. 3 shows the structure of a conventional air blower device for a unit bath of this type.

In the figure, 21 is a bathroom, 22 is a wall panel that constitutes the bathroom 21, 23 is a pan, and 24 is a bathtub.

The conventional air blower device includes an air blower nozzle 25 provided at the bottom of the bath 24, and an air supply unit 27 that supplies air to the air blower nozzle 25 through an air supply pipe 26.
Intake pipe 2 for supplying air to the air supply unit 27
8 and.

The air supply unit 27 is provided with an air pump and a controller (both not shown) in a casing, and is covered by a wall panel 22, a side wall 24a of the bathtub 24, and an overhanging upper edge 24b of the bathtub 24. It will be installed in the open location (apron).

The intake pipe 28 has an open end extending to the outside of the wall panel 22, and sucks air from between the wall panel 22 and the wall W of the frame forming the installation space.

The open end of the intake pipe 28 may rise along the outer surface of the wall panel 22.

<Problems to be Solved by the Invention> As described above, the air blower device for the unit bath sucks air from between the wall panel 22 which is the outer wall of the unit bath and the wall W of the body forming the installation space. However, foreign matter such as dust and insects may be sucked into the intake pipe 28, and such foreign matter may cause a malfunction such as a failure of the air pump.

On the other hand, it is conceivable to attach a filter or a net to the open end of the intake pipe 28, but if the filter or net is provided directly on the intake pipe 28, the ventilation area will be small and clogging will occur early. Occurs, resulting in poor intake.

Further, considering that only a narrow gap is formed between the unit bath and the wall W of the skeleton, a large net such as a cylindrical net cannot be provided at the open end of the intake pipe 28.

The present invention has been made in view of the above-mentioned problems, and can be installed in a narrow gap outside the unit bath, and has an intake structure that exhibits good dust and insect repellent effects without causing clogging for a long period of time. The challenge is to provide.

<Means for Solving the Problems> The present invention provides an air intake structure of an air blower device for achieving the above object, which inhales air from the outside of a wall panel of a unit bath through an intake pipe and ejects bubbles into a bath. , The intake pipe has a rising portion at its open end,
The rising part rises along the outer surface of the wall panel and opens at a position higher than the upper edge of the bathtub.A dustproof net is provided around the opening end, and the dustproof net is flat on the outer surface of the wall panel. It is attached to the enclosure and surrounds the open end of the rising portion.

<Operation> In the above configuration, since air is taken in through the dustproof net and the intake pipe inside thereof on the outside of the wall panel, foreign matter does not flow into the intake pipe. In this case, since the dustproof net spreads along the outer surface of the wall panel, it does not take up space and has a sufficiently large ventilation area so that it does not become clogged even if it is used for a long time.

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

FIG. 1 is a sectional view of an air blower device having an intake structure according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a part of the intake structure.

In FIG. 1, reference numeral 1 is a bathroom, 2 is a wall panel constituting the bathroom 1, 3 is a pan, and 4 is a bathtub.

The air blower device of this embodiment includes an air blower nozzle 5 provided at the bottom of a bath 4, an air feed unit 7 that feeds air to the air blower nozzle 5 through an air feed pipe 6, and an air feed unit from the outside of the wall panel 2. It is the same as the conventional example shown in FIG. 3 in that it comprises an intake pipe 8 for supplying air to 7.

The air supply unit 7 is provided with an air pump and a controller in the casing, and the wall panel 2 and the bathtub 4 are provided.
It is also the same as the conventional example in that it is installed at a portion covered by the side wall 4a of the above and the overhanging upper edge 4b of the bathtub 4.

In this embodiment, two intake pipes 8 are provided, each of which penetrates the wall panel 2 and is fixed by a mounting flange 9.

The air blower device of this embodiment is characterized by an air intake structure using the air intake pipe 8 and is different from the conventional example in that the wall panel 2 is used.
The rising portion 8a of the intake pipe 8 and the dustproof net 10 are provided outside the.

The rising portion 8a of each intake pipe 8 rises along the outer surface of the wall panel 2 and opens at a position higher than the bathtub upper edge 4b.

The dustproof net 10 flatly surrounds the periphery of the open end of the rising portion 8a of the intake pipe 8 along the outer surface of the wall panel 2, and as shown clearly in FIG. It is stretched between 11 and the lower plate 12. The rising portion 8a of the intake pipe 8 penetrates the lower plate 12 of the upper and lower plates 11 and 12, and the rising portion 8a is opened between the upper plate 11 and the lower plate 12. The upper and lower plates 11 and 12 and the dustproof net 10 are the reinforcing plates 1 on the left and right sides.
It is attached to the outer surface of the wall panel 2 through 3, 13.

Inside the wall panel 2, each intake pipe 8 is connected to the base of the air supply unit 7 side and a flexible tube 1 such as a rubber tube.
Connected with 4.

In the above configuration, air is taken in from the outside of the wall panel 2 by the operation of the air supply unit 7, and is sent to the air blower nozzle 5 through the air supply pipe 6, and the air blower nozzle 5 forms air bubbles into the bath 4 Gushes into.

At this time, on the outside of the wall panel 2, the dustproof net 10 and
Since air is taken in through the rising portion 8a of the intake pipe 8 inside the intake pipe 8, foreign matter does not flow into the intake pipe 8.

Here, since the dustproof net 10 is stretched between the upper plate 11 and the lower plate 12 and extends in the vertical direction along the wall panel 2, it is possible to secure a sufficiently large ventilation area, No clogging even after long use. Further, since the falling dust is received by the upper plate 11, it is difficult for the dust to adhere to the dustproof net 10 and clogging can be well prevented for a long period of time. Moreover, since it does not take up space for the ventilation area, it can be accommodated in a state in which there is a margin in the gap with the wall W of the skeleton.

If the hot water in the bathtub 4 flows back to the air supply unit 7 through the air supply pipe 6 when the intake pipe 8 is opened at a low position outside the wall panel 2, the hot water is sucked in. Although it overflows to the outside of the unit bath through the pipe 8, in the present invention, since the rising portion 8a of the intake pipe 8 is opened at a higher position than the upper edge 4b of the bathtub 4, the hot and cold water in the bathtub is exposed to the outside of the unit bath. It does not overflow.

Further, in the above-mentioned embodiment, the type provided with the two intake pipes 8 is illustrated, but the present invention is not limited to this.
It can also be implemented as a type with a book intake pipe.

<Advantages of the Invention> As described above, according to the present invention, since air is sucked through the dustproof net spread flat along the outer surface of the wall panel, the ventilation area is large and clogging occurs for a long time. In addition, it is possible to smoothly inhale air while blocking the inflow of dust and insects.

Further, since the dustproof net is provided flat along the outer surface of the wall panel, the dustproof net can be installed in the narrow gap between the wall of the skeleton and the case without any trouble.
