Description

[Detailed description of the invention] Industrial applications This invention relates to a bathtub.

Conventional technology Conventionally, as a method of heating the washing area in a bathroom, an electric heating panel is embedded under the floor of the washing area in the bathroom.
There is a method of laying mortar and tiles on top of it.

There are also some that have hot water circulation pipes embedded in them instead of electric heater panels.

Problems to be Solved by the Invention However, with such a structure, for example one with an embedded electric heater panel, water may seep into the cord connection area, and there is still a risk of electrical leakage. Alternatively, if hot water circulation pipes are buried under the floor of the washing area, it is necessary to install a hot water supply system for heating, and even if one is already installed, hot water must be guided to the buried circulation pipes. (This required new piping work.

Therefore, the present invention provides a bathtub that can perform safe floor heating of a washing area without requiring large-scale piping work or other heat sources such as electricity.

Means for Solving the Problems In order to solve the above problems, the present invention provides a bag-like part having a part that becomes the floorboard of the washing area, and a bag-like part is provided between the inside and the bag-like part on the upper part of the wall board. A first water through hole that allows communication between the walls is provided, and a second water through hole is provided below the first water through hole in the wall plate.

Function: With the above structure, the hot water in the upper part can smoothly enter the bag-shaped part through the first water flow hole provided at the top, and the hot water can cool down through the second water flow hole provided at the bottom. This forms a return path for the hot water, so that the hot water that has cooled and descended within the bag can return through the second water through hole, and to compensate for this, the hot water that is hotter than the first water through hole can be returned. The hot water enters, and this convection allows the hot water inside the bag to maintain an appropriately warm temperature, and the washing area floorboards are appropriately heated by the hot water inside the bag. Furthermore, if floor heating is not required, heating can be easily stopped by blocking at least only the first through-hole in the upper part.

EXAMPLE A first example of the bathtub according to the present invention will be described below. FIG. 1(A) shows a cross section of a bathroom using the bathtub of this embodiment, and FIG. 1(B) shows the same bathroom as seen from above. In FIG. 1(a), 1 is the upper piece of the main bathtub, and 2 is the lower piece. A bathtub section 3 for people to enter and a washing area 4 are integrally formed in the upper piece 1. On the other hand, the lower bead 2 is configured such that the entire upper piece 1 can be housed therein. And upper piece 1
The outer edge 5 of the outer edge 5 of the lower piece 2 and the outer edge 6 of the lower piece 2 are configured to fit into each other. When the upper piece 1 and the lower piece 2 are fitted together, the upper piece 1 and the lower piece 2 form a double structure. A hollow part 7 is formed between the upper piece 1 and the lower piece 2.The hollow part 7 is located below the bathtub part 3 and the washing area 4, and below the bathtub part 3 and the washing area 4. It is formed on the side and surrounds the bathtub section 3 and the washing bath section 4.

8 is a side through hole provided on the side of the bathtub 3; 9 is a bottom through hole provided below the bathtub 3; are in communication with each other. A plurality of side flow holes 8 are arranged side by side in the horizontal direction.

Reference numeral 10 denotes a cold water suction port connected to an external bath pot, and 11 a hot water discharge port arranged above the cold water suction port IO and connected to the bath pot.

A bathtub side drain port is provided in a portion of the lower piece 2 that coincides with the bottom through hole 9 provided in the upper piece 1,
A rubber stopper 12 is fitted into the drain port. The rubber stopper 12 is attached to the side of the bathtub section 3 by a chain, and is inserted through the bottom through hole 9 and fitted into the drain port on the bathtub side. - A washing water side drain port 13 is provided in a portion of the upper piece 1 that forms the floorboard 4a of the washing area 4.

14 is a concrete floor that supports the bathtub, and 15 is a block that supports the bathtub body. A drain pipe 16 is embedded in the floor 14, and the drain pipe 16 is connected to the bathtub side drain port of the lower piece 2 and the washing water side drain port 13 of the upper piece 1.

In FIG. 1(b), 17 is a concrete floor placed on the side of the bathtub body, and 18 is a tile laid next to the floor 17.

In this embodiment, the hot water stored in the bathtub 3 enters the hollow part 7 through the side flow holes 8 and the bottom flow holes 9, and the floorboard 4a of the washing area 4 is warmed by the entered hot water.
Underfloor heating is provided. That is, high-temperature hot water discharged from the hot water outlet 11 enters the hollow portion 7 through the side flow hole 8 and warms the side wall and floorboard 4a of the washing area 4. However, the cooled hot water descends downward and returns to the string through the bottom through-hole 9. and,
To compensate for this, hot water further enters the hollow portion 7 through the side flow hole 8.

In this embodiment, especially in winter, all of the side through holes 8 are opened to allow high-temperature water to actively flow into the hollow part 7, but in summer, floor heating in the washing area is almost not necessary. 8 is kept cold to prevent high-temperature water from flowing into the hollow part 7. Although the hollow part 7 is still filled with water, it is hardly heated because the inflow of high-temperature water is blocked. In addition, since the side through-holes 8 are small holes, the lid that closes them only needs to be small, making it very easy to use.Furthermore, the number of holes left open among the plurality of side through-holes 8 can be changed. As a result, high temperature water flows into the hollow part 7.
The amount of hot water flowing into the hollow part 7 can be changed, and the temperature of the hot water in the hollow part 7 can be adjusted.

Furthermore, as the device is used for a long period of time, dust such as hot water scale will adhere to the side wall surface of the hollow portion 7, and the peeled off dust will accumulate below the hollow portion 7. Then, the dust accumulated below the hollow part 7 is discharged from the bathtub-side drain port provided in the lower piece 2, and flows into the bathtub part 3 through the side through-hole 8 and the bottom through-hole 9. There isn't.

A second embodiment of the present invention will be described below. In FIG. 2, 20 is a lower piece and 21 is an upper piece. The lower piece 20 is joined below the upper piece 21,
A hollow portion is formed between the lower piece 20 and the upper piece 21. The floor plate 22 of the neck portion formed in the piece 21 is much higher than that of the first embodiment, and is approximately at the same height as the side flow hole 23. In addition, the side flow hole 23 is provided at a slightly higher position than the hot water outlet 24 connected to the bathtub, and the hot water smoothly flows into the hollow part, especially the hollow part 25 below the floorboard 22. be able to. Further, the portion 26 of the lower piece 20 facing the floor plate 22 is sloped so as to gradually become lower toward the bathtub portion 27, so that the cold water can easily return to the bathtub portion 27 side. There is. 28 is a heat insulating material provided outside the main bathtub.

Effects of the Invention The present invention provides a bag-like part having a part that becomes the floorboard of a washing area, and has a first water flow hole in the upper part of the wall board to enable communication between the inside and the bag-like part, and the above-mentioned water passage hole. By providing the second water flow holes below the first water flow holes,
The hot water can flow smoothly inside the bag, and the hot water inside the bag can be maintained at a moderately warm temperature due to convection, and the washing area floorboards can be appropriately heated by the hot water inside the bag, making it possible to create large-scale installations. There is no need to carry out any plumbing work,
Safe and efficient floor heating can be performed. However, if it is not needed, the floor heating in the washing area can be stopped by simply blocking the first water flow hole.
