BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a 24-hour bath water purifying and circulating apparatus equipped with a heat storage tank which is another heat retaining means.

[0002]

2. Description of the Related Art Conventionally, in a bath water purifying and circulating apparatus for bathing for 24 hours, hot water (bath water) is always ready for bathing at an appropriate temperature. In addition, it should be bath water from which scales have been removed. Further, the bath water needs to be sanitized from the viewpoint of hygiene. In addition, in the bath water purifying circulation device, generally, a jet jet or the like is provided at a circulating outlet or the like so as to stimulate the body.

[0003]

DISCLOSURE OF THE INVENTION A 24-hour bath water purifying circulation device is becoming popular in the market because it is convenient for bathing 24 hours a day. The conventional 24-hour bath water purifying circulation device mainly uses electric energy as a heat source, and since it keeps warm for 24 hours, the energy is supplied almost continuously or intermittently within 24 hours. Had to supply. Therefore, there is an inconvenience that a large amount of electricity is required. On the other hand, there are many electric water heaters that use night-time electricity, etc., and are widely used in the market.
The advent of time bath water purification circulation device is also desired. When water is used as the heat storage material, the heat storage temperature is low,
There was a drawback that it could not be used beyond the range and the device became large.

[0004]

Therefore, as a result of intensive studies, the inventor of the present invention has found that the invention is based on a circulation pump for circulating bath water and sterilization for sterilizing the bath water. The bath water is provided with a bath water purifying circulation device comprising a device and a filtration device for filtering fine dust and impurities from the bath water, and the bath bath and the bath water purifying circulation device are connected to the input side circulation pipe and the output side circulation pipe. The heat storage water tank of the heat storage tank that heats the water with the heat storage medium by the power source has a heat storage pipe section so that the heat storage water tank section is in parallel with the bath water purification circulation device. The input side heat storage pipe is communicated with the heat storage pipe part through a circulation path switching means that is arranged and only switches to the bath water purifying circulation device side or the heat storage tank side only, and the other side of the output side heat storage pipe from the heat storage pipe part Edge can flow into the bath A 24-hour bath water which is provided in the bath water and detects when the temperature of the bath water has dropped and controls the bath water to a predetermined temperature by automatically flowing out the heated piping hot water circulated to the heat storage water tank side. By using the purification circulation device as a heat storage tank in the nighttime power usage mode, it is possible to dramatically reduce the power energy cost, downsize the device, and make it safe for the human body. It is a solution to the problem.

[0005]

Normally, the bath water circulates between the bath and the bath water purifying circulation device. However, when the temperature of the bath water drops, the circulation passage switching means switches the flow passages so that the heat storage tanks in the heat storage tanks are arranged in parallel. By circulating the bath water in the heat storage pipe and exchanging heat with the bath water, the water temperature in the bath can be kept constant.
