Description

[Detailed Description of the Invention] This invention relates to an improvement of a bathtub, particularly a bathtub in which a heat exchanger for exchanging heat by circulating hot water is installed in the bath.

In the hot water circulation indirect heating method, a heat exchanger mainly consisting of hot water circulation pipes is installed in the tank using an injection means, and hot water supplied from the boiler is passed through the heat exchanger to heat the hot water in the tank. A plate-shaped cover is attached to the front of the heat exchanger in the bath to prevent direct contact with the heat exchanger in order to ensure safety during bathing. However, in the conventional structure, in order to attach the cover, the cover is screwed to a stay protruding from the side wall of the bathtub, so bolt holes for attaching the stay are drilled in the bathtub wall, but water leaks from the hole. There is a high risk of leakage.

Therefore, this idea was developed to cover the heat exchanger (plate-shaped).
When installing the bathtub, a groove is provided in the bottom wall of the bathtub, and the lower edge of the cover is fitted into this groove so that the cover stands upright in the bathtub. To provide a bathtub in which a cover can be attached without having to do so.

Next, this invention will be explained in detail with reference to illustrated embodiments.

Figure 1 shows an example of this invention.
Reference numeral 1 is a bathtub made of materials such as FRP and enamel, and a heat exchanger (not shown) mainly consisting of a hot water circulation pipe is installed along one side wall 11 of the bathtub 1 by inserting it. It's getting old. Hot water circulation to the heat exchanger is performed by hot water supply from a separately installed boiler, and the hot water supply pipe and hot water outlet pipe connected to the heat exchanger are installed so as to straddle the upper surface of the side wall 11 of the bathtub 1. .

A plate-shaped cover 2 is attached to the heat exchanger installed in the tank, and the cover 2 is made of a water-resistant material such as plastic or metal. The cover 2 of the first embodiment includes a partition part 21 that covers the front surface of the heat exchanger (facing the inside of the tank), an upper surface part 22, and a hook part 23 that is hooked to the bathtub side wall 11. The lower edge 24 is bent into an L shape,
It is designed to have good contact with the bottom wall 12 of the bathtub 1. A plurality of slits 25 are provided in the partition portion 21 so that convection of hot water can occur. In addition, instead of providing slits in the partition part 21, the width and height dimensions of the partition part 21 are shortened, and the side walls 13, 14 and bottom wall 1 of the bathtub facing each other are shortened.
2 may be provided, and convection may be effected through these gaps.

To attach the cover 2 to the bathtub, attach the partition part 21
A pair of grooves 15 and 16 are provided in the bottom wall 12 of the bathtub, and the lower edge 24 of the partition 21 that is dropped into these grooves fits into the bottom wall 12 of the bathtub. Partition part 2 of cover 2
1 is placed upright in the tank and a cover 2 is attached.

The grooves 15, 16 are bifurcated protrusions 15a, 15b, 16a, 16b that are integrated and project upward from the lower ends of the opposing side walls 13, 14 to the bottom wall.
The width of the grooves 15 and 16 is
The lower edge 24 of the partition part 21 of the cover is dimensioned to fit snugly into the cover so that it can be freely inserted and removed.

The chain 31 of the stopcock 3 can be fixed to the partition part 21 of the cover 2, and the upper surface part 22 can also be integrally provided with a recessed part to serve as a soap holder.

As mentioned above, according to this invention, the cover provided on the front side of the heat exchanger installed in the bathtub is attached by fitting the lower edge of the cover into the groove in the bottom wall of the bathtub. There is no need to protrude a stay to attach the cover, and there is no need to drill holes that can cause water leakage.The cover can be attached by simply fitting the lower edge of the cover into the groove that is integrally formed at the same time as the bathtub is formed. Furthermore, since it has a simple shape with protrusions protruding upward from the bottom wall, it is easy to cut out molds when manufacturing bathtubs, and does not increase manufacturing costs. To obtain a bathtub that can be installed efficiently and has no risk of water leakage at a low cost.
