Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bath overflow device that allows hot water to overflow from a bathtub every time a bather enters the bathtub.

[Conventional technology]

Regardless of the type of bathhouse, the overflowing of hot water from the bathtub every time the bather takes a bath gives the bather a very refreshing feeling. Traditionally, bathhouse managers judged the situation visually.
The hot water is replenished as the situation deteriorates.

[Problem that the invention seeks to solve]

However, in conventional baths, after many bathers exit the bathtub at the same time, the scene suddenly decreases, making it impossible to replenish the hot water and providing a refreshing feeling to the next bather. There is this inconvenience. As shown in the box, the amount of hot water overflowed by -1 bathers is approximately 50 liters.

[Means for solving problems]

The present invention has been made in view of the above, and it makes it possible to almost eliminate the time to prepare hot water (heating time), so that hot water can be refilled at any time, and even after many bathers have left the bathtub, it is possible to start the next bath. To provide a hot water bathing device for a bath, which collects hot water overflowing from a bathtub on the outer wall surface of the bathtub and returns it to the bathtub in order to prevent overflow from occurring.

Hereinafter, the bath water bath apparatus according to the present invention will be explained in detail.

〔Example〕

FIGS. 1 and 2 show an embodiment of the present invention, in which a bathtub 1
The interior is filled with hot water at the highest water level, just before overflow, and is separated from the washing area 3 by a partition wall 2. A slit 4 is formed on the upper surface of the partition wall 2 to diffuse and slow down local overflow, and a water collection groove 5 is provided on the outer wall surface of the slit 4. Outer edge of bulkhead 2 and water collection? ! The distance g between the inner walls of #5 is 0≦g≦2 based on experimental results and aesthetics.
A value of about 0 dragons is appropriate. There is a drain 6 on the floor of the washing area 3.
A water level sensor 7 (for example, constituted by a pair of electrodes) is provided at a predetermined position on the inner wall surface of the bathtub 1. The water collection groove 5 communicates with the water channel 9 via the perforated plate 8,
It communicates with the water collection tank 10 via the filter F. A plurality of water channels 9 are formed in the length direction of the water collection groove 5 and are connected to the water collection tank 10 in parallel. The water collection tank 10 is provided with a temperature sensor 11, and is also equipped with a pump P and a heater H.
A waterway 12 is connected thereto. The water level sensor 7 and the temperature sensor 11 are a control unit 1 such as a microcomputer.
3, and the control unit 13 is connected to the pump P and the heater I.
] is designed to control the drive.

In the above configuration, the operation will be explained as follows. The bathtub 1 is filled with hot water to the highest water level, and when a bather enters the bathtub 1, the water level rises as shown by the dotted line and an overflow O occurs. The overflow O is dispersed by the slit 4 and is slowed down to flow thinly along the wall surface of the partition wall 2. As a result, water collects f5 due to the surface tension of hot water.
The water is efficiently collected in a water collection tank 10, filtered to remove dirt and the like by a filter F, and collected in a water collection tank 10. In this way, in order to collect water by the surface tension of hot water, the above-mentioned interval g should be set to 0≦g≦
It can be made as small as 20 pieces, which is desirable from an aesthetic point of view. When the water level in the bathtub 1 falls, the control unit 13 drives the pump P based on the signal from the water level sensor 7, returns hot water in the water collection tank 10 to the bathtub 1, and maintains it at the highest water level.

At this time, the control unit 13 drives the heater H according to the signal from the temperature sensor 11 to set the temperature of the hot water to be replenished to a predetermined value.

Note that the water collection tank 10 may be provided at a level where the water level of the water collection tank 10 is the same as the water level of the bathtub 1. In this case, the water channel 9 will also be provided with a pump.

〔Effect of the invention〕

As explained above, according to the bath water bath system of the present invention, hot water overflowing from the bathtub is collected on the outer wall of the bathtub and returned to the bathtub, so that it takes less time to prepare the hot water. You can constantly replenish hot water with almost no need.

Therefore, even after a large number of bathers have left the bathtub, the next bather will overflow, providing a refreshing feeling at all times.
