Description

The present invention relates to a bath device.

(Prior Art) The water level of a bathtub in a conventional bath device for home use or the like fluctuates depending on the person entering the bath device.

Therefore, if the water enters the bathtub at a high water level, the hot water overflows from the upper part of the bathtub, and this overflowing hot water is wasted. Therefore, when pouring hot water into the bathtub, it is necessary to pay attention to the water level, and if this is not done, there is waste. Also, the water level depends on the physique, and the water level drops after a person with a large physique takes a bath. Therefore, the next person to bathe had to add hot water or settle for a lower water level.

Therefore, a circulation type bath device (see, for example, Japanese Utility Model Publication No. 49-5539) is also proposed in which overflowed hot water is collected in a hot water storage tank and is returned to the bathtub again.

(Problems to be Solved by the Invention) However, in the conventional bath device of such a system, since the hot water is collected from the bathtub to the hot water storage tank by a pipe or a simple gutter-shaped collecting member, the hot water is collected. If you configure a large amount, when a person enters the bathtub and the water level rises,
Since the hot water flows into the hot water storage tank at once, it is easy to cause inconveniences such as backflow of hot water due to discharge of air from the hot water storage tank and an unpleasant sound. On the contrary, if the amount of hot water collected is not enough, the collection member cannot collect all of it,
The inconvenience of overflowing from the upper edge of the bathtub occurs.

Furthermore, in the conventional bath device of the above-mentioned type, the collection and return mechanism of the hot water is not necessarily reflected in the aesthetics.

The present invention aims to solve such problems.

(Means for Solving the Problem) The means for solving the above-mentioned problem will be described with reference to the drawings showing an embodiment. Except for the entrance / exit location 12, a wide gutter-shaped hot water recovery path 2 is constructed, and the hot water recovery path 2 is also provided.
The partition wall 14 between the bathtub body 13 and the bathtub body 13 is provided with the overflow notch 11 having the gently inclined portion 15, and the communication port 6 to the hot water storage tank 3 is provided on the downstream side of the hot water recovery path 2 to store hot water. A reflux path 5 having a pump 4 for refluxing hot water from the water tank 3 to the bath 1 is provided.

In the above structure, the overflow notch 11 can be formed in a plurality of places.

(Operation) In the above-described structure, a person can easily enter and exit the entrance / exit point 12 provided at a part of the upper edge of the bathtub 1 without causing the wide gutter-shaped hot water recovery path 2 to get in the way. You can enter and leave bathtub 1.

When a person enters the bathtub body portion 13 and the water level rises, the hot water in the bathtub body portion 13 overflows through the overflow notch 11 and flows into the hot water recovery path 2, where it flows and flows out from the communication port 6. Then, hot water is temporarily stored in the hot water storage tank 3. The hot water in the hot water storage tank 3 flows through the reflux path 5 by the pump 4 and flows back into the bathtub 1 again, so that the overflowed hot water is not wasted.

Therefore, in the present invention, the water level of the bathtub 1 can be constantly maintained at a high overflowing water level, and when a person enters the bathtub 1, the water level can be overflowed with great satisfaction. .

Since the overflow notch 11 has the shape having the gently sloping portion 15, the width in which the hot water overflows becomes wider as the water level rises. Therefore, when a person enters the bathtub and the water level rises, a small amount of hot water initially overflows from the narrow width portion, and the overflow amount also increases as the width of the overflow water gradually increases. In this way, the hot water overflows from the bathtub body 13 through the overflow notch 11 to the hot water recovery path 2 relatively slowly, so that the hot water does not overflow to the outside of the hot water recovery path 2 due to the force, and Since it does not flow into the hot water storage tank 3 all at once, it is possible to prevent the generation of unpleasant noise due to the discharge of air in the tank 3, and to enjoy the flow of hot water flowing through the wide gutter-shaped hot water recovery path 2.

(Embodiment) Explaining the embodiment of the present invention as described above, the above-described reflux control can be easily performed by providing the overflow water detection means 7 in the hot water storage means 3. For example, when hot water is introduced into the hot water storage means 3 and is detected by the detection means 7, it is possible to detect overflow water, that is, a person has entered the bathtub 1, and based on such detection, a predetermined value is determined. The reflux control can be automatically performed.

In addition, the hot water return part 8 to the bathtub 1 can be appropriately configured. The reflux section 8b indicated by the two-dot chain line in FIG. 1 is configured inside the bathtub 1, and the reflux section 8a indicated by the solid line.
Is configured above the bathtub 1. In the latter case, the flow of the refluxed hot water is reminiscent of a hot spring bath by constantly returning the hot water during bathing, which can further enhance satisfaction and, in the former case, bubbles in the reflux section 8b. It is possible to further enhance the feeling of satisfaction when taking a bath by configuring the generating part. Of course, it is also possible to provide both of the reflux units 8a and 8b and operate them appropriately. The hot water lost from the reflux system due to the first hot water supply or use of hot water in the bathtub 1,
The hot water supply device 9 or the like may be appropriately replenished, and the hot water temperature may be maintained by using the hot water supply device 9 or may be additionally heated by a bath pot 10 or the like provided as needed to maintain an appropriate temperature.

(Effects of the Invention) As described above, the present invention causes hot water to overflow from the upper part of the bathtub during bathing, and causes the overflowed hot water to flow into the hot water recovery path at the upper edge of the bathtub, and then from the hot water storage tank to the reflux path to the bathtub again. Since it is configured to recirculate, the overflowed hot water is not wasted and the water level in the bathtub is raised without paying attention to collecting it.
The water level can be maintained at an overflowing level, and when a person enters the bathtub, overflowing water makes it possible to take a very satisfying bath, and since the water level in the bathtub does not depend on the physique, a person with a large physique can take a bath. This has the effect of not causing the inconvenience of lowering the water level after the operation.

Particularly, in the present invention, since the hot water recovery path is formed in a wide gutter shape,
You can enjoy the flow of overflowing hot water, and since this hot water recovery route is not provided at a part of the upper edge of the bathtub, but there is a place for entrance and exit, there is a wide gutter-shaped hot water recovery route. There is an effect that it does not hinder people from entering and leaving the bathtub.

Further, in the present invention, the amount of hot water overflowing from the bathtub body to the hot water recovery path is automatically adjusted by the water level of the hot water inside the bathtub body, so that the hot water overflows outside the bathtub or rapidly into the hot water storage tank. There is an effect that it is possible to prevent an unpleasant sound from being generated due to a large drop.
