DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overflow bathtub device for overflowing hot water from a bathtub.

[0002]

2. Description of the Related Art In recent years, a so-called overflow bath tub apparatus has been commercialized, which is provided with a hot water tank for supplying hot water in a full state so that the hot water always overflows and temporarily store overflowing hot water. In this overflow bathtub apparatus, hot water is supplied to a bathtub, overflowed and stored in a hot water storage tank, and the overflowed hot water is collected in a water heater and returned to the bathtub again from a reheating system of the hot water supply means.

[0003]

However, when taking a bath, the circulation of warm water in the bathtub is hindered by the human body and decreases, and floating matters such as garbage and scales floating on the warm water and on the surface of the warm water are reduced. , It becomes difficult to flow out to the hot water tank side, and suspended matter such as garbage and scales stays on the hot water surface of the bathtub,
It is unsightly and causes discomfort. Therefore, the present invention
It is an object of the present invention to provide an overflow bathtub device that prevents staying of floating matter in warm water and prevents discomfort due to staying of floating matter.

[0004]

The overflow bathtub apparatus of the present invention overflows hot water as illustrated in FIGS.
A bathtub (2), the bathtub being provided on a wall portion of the bathtub;
Hot water storage that temporarily stores the hot water overflowing from
Tank (mini-tank 5) and the hot water from this hot water storage tank.
The bathtub and the storage tank are connected by a circulation path returning to the bathtub side.
Hot water supply means (water heater 3) connected to the hot tub;
Provided on the inner wall side near the bottom and connected to the circulation path
The hot water from the hot water supply means to the bottom of the bathtub.
With a hot water spout (hot water spout 7)
The hot water tank and the hot water jet
A bathtub set on the inside and outside of the same wall side of the bathtub.
Thus, the hot water jetting tool was injected into the bathtub.
With hot water from the bottom of the bathtub to the hot water tank via the inner wall surface
It is characterized by causing reflux to flow out . With this configuration, the hot water spouting tool sprays the water into the bathtub.
Hot water flows from the bottom of the bathtub to the hot water tank via the inner wall surface.
A reflux can be generated , and the floating matter in the hot water can be flowed to the hot water tank side. That is, even during bathing,
The hot water jetted into the bathtub is promoted to be stirred in the bathtub. At this time, the hot water flows from the hot water jetting tool on the hot water tank side toward the opposing inner wall surface of the bathtub, toward the hot water surface, and from the hot water surface to the hot water tank, so that the hot water surface Not only that, garbage and the like existing in the lower and middle layers of the bathtub are easily discharged to the hot water storage tank without stagnation. Therefore, the floating matter of the hot water in the bathtub flows out to the hot water storage tank side along with the circulation of the hot water, and the stay in the bathtub is prevented, so that discomfort of the bather can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

FIG. 1 and FIG. 2 show an embodiment of an overflow bathtub apparatus. The overflow bathtub apparatus 1 is connected to and connected to a bathtub 2 through a reheating pipe 4 for supplying hot water from a water heater 3 as a hot water supply means. Hot water supplied from the water heater 3 is supplied to the overflow bathtub device 1.
A mini-tank 5 is provided as a hot water tank that constantly overflows and temporarily stores overflowing hot water. From the bottom of the mini-tank 5, a mini-tank return pipe 6 for recovering hot water is connected to the water heater 3.

Bathtub 2 provided with mini-tank 5 of bathtub 2
A hot water jet fitting 7 is provided on the inner wall side as a hot water jet part, and the additional heating pipe 4 is connected. It should be noted that the hot water jet fitting 7 may be of a type whose hot water jetting direction is adjustable.

With such a configuration, if the hot water is constantly circulated between the water heater 3 and the bathtub 2 during bathing, the bathtub 2
The hot water spouted inside is stirred in the bathtub 2 and does not stagnate. That is, the hot water that has flowed out from the hot-water jet fitting 7 flows toward the wall surface of the bathtub 2 facing the hot-water jet fitting 7, flows upward, reaches the mini-tank 5 side toward the hot water surface, and returns to the bottom again. Move towards.

At this time, when the jet direction of the hot water is directed to the bottom of the bathtub, the flow of the hot water is formed from the bottom toward the hot water surface and from the hot water surface to the mini-tank 5, as shown in FIG. The entire hot water in the bathtub 2 is in a flowing state. Therefore, suspended matter such as garbage and scale can easily overflow with the warm water without stagnating in the warm water, and can be discharged from the bathtub 2 to the mini tank 5 side.

As described above, the suspended matter such as garbage and scales existing in the warm water easily overflows with the warm water without stagnation in the warm water due to the warm water flow formed by the warm water ejecting metal fitting 7 and flows into the mini tank 5. Since it can be removed by inflow, comfortable bathing is not impaired.

[0013]

As described above, according to the present invention,
The following effects can be obtained. a. Since floating substances such as garbage and scale can be discharged out of the bathtub by generating a hot water flow in the bathtub, discomfort can be reduced. b. Since the hot water ejection part is arranged on the bathtub wall side, the structure of the apparatus can be simplified, and the manufacturing process can be simplified, so that the manufacturing cost can be reduced. c. The direction of the hot water flow can be changed arbitrarily, and the suspended matter can be effectively drained out of the bathtub.
