Description

[Detailed Description of the Invention] This invention relates to a bottom plate for a bathtub, and more specifically, to a bottom plate for a bathtub used in a direct-fired bathtub or the like.

BACKGROUND ART Conventionally, so-called direct-fired bathtubs, in which a heat source is placed directly below the bathtub to directly heat the water in the bathtub, have been widely used as they are considered to be advantageous in terms of thermal efficiency and the like.

By the way, in this type of bathtub, since the inner bottom of the bathtub is heated, it is necessary to use a separate bottom plate.As the bottom plate, it has been proposed that a heat-resistant substrate having legs on the back side is submerged in the bathtub in advance, and, It is used.

However, while this type of bottom plate has the advantage of being more convenient than the conventional floating lid that is floated on top of hot water and submerged during bathing, the bottom plate also gets quite hot while heating the hot water. There was a time when I was told that it could be dangerous because it could be dangerous.

Furthermore, conventionally, it has been widely practiced to place a bubble generator such as a bubble plate in the bathtub, but in the case of the above-mentioned direct-fired bathtub, the bottom plate and bubble plate are placed inside the bathtub, and each time you take a bath, They had the disadvantage that they had to be taken in and taken out, which was cumbersome to handle, and they were also difficult to manage when not in use.

This invention was devised in view of the above-mentioned drawbacks with the purpose of providing a bottom plate for a bathtub in which a bubble plate or the like can be integrally combined with the bottom plate, and which is easy to handle and manage. A cell board is made by stacking a top plate made of uniformly dispersed perforations on a bottom plate with a gap between them, airtightly joining the periphery, and supplying air under pressure into the gap to eject air bubbles. , on a heat-resistant substrate with legs on the back side,
It is characterized in that it is removably fitted integrally with a band member fitted around the periphery.

This invention will be explained below using examples.

Figure 1 is an exploded perspective view of an embodiment of this invention;
The figure is a perspective view showing the assembled state of the embodiment, and FIG. 3 is an enlarged sectional view of the main part taken along the line - in FIG. 1.

The bathtub bottom plate A of this invention has a large number of micro holes 1A.
A surface plate 1 such as a metal plate formed by uniformly dispersing and perforating 1A is placed on the bottom plate 2, for example, as shown in an enlarged view in FIG.
By press-molding A, this protrusion 2A
The air pipes 3 are stacked so as to form a gap h, and the periphery 12 is hermetically joined.
A band body 6 having a U-shaped cross section, for example, is fitted around a heat-resistant substrate 4 having legs 5 on the back surface 4A, and a bubble plate 10 which is configured to supply air under pressure and blow out bubbles. As shown in FIG. 2, they are constructed so that they can be attached and detached and are integrally stacked on top of each other.

In the above embodiment, the bubble plate 10 is made of a metal plate so as to have enough strength to withstand even when weight is applied thereto, and also to minimize the volume occupied in the bathtub (not shown) for handling purposes. Due to the need to reduce the size, it is desirable to make the total thickness as thin as possible.

Note that the press protrusion 2 as shown in FIG.
If the metal plate having A is used as the bottom plate 2 and this is combined with the top plate 1, the total thickness of the bubble plate H
can be effectively reduced and eject uniform air bubbles,
In addition, even if the load-bearing strength is around 100 kg, the total thickness of the whole can be set to around 2 to 3 mm.

Further, the heat-resistant substrate 4 may be made of metal such as aluminum light alloy, or may be made of thermoplastic synthetic resin or thermosetting synthetic resin having a high melting point.

This idea is structured as above, so
When used as the bottom plate of a direct-fired bathtub, bubble plate 1
0 can be integrally combined, so it can be handled and managed as a single bottom plate for a bathtub, which is convenient and can also be stored separately by removing the band body 6 when not in use. In addition, according to the bathtub bottom plate of this invention, if it is used in a bathtub with a bubble plate attached, the bubble plate 10 also serves as a heat insulating material, so it is heat resistant. It has various effects such as preventing dangers such as burns to bathers even if the substrate 4 is heated to high temperatures.
