The state is switched to the backwashing state in which the filter body 2a is allowed to pass through the filter body 2a, and the filter body 2a is backwashed.
Foreign matter trapped in a is easily removed by backwashing.

These foreign matters are automatically discharged to the outside from the leakage matter discharge passage 16 opened by the discharge valve 17. Then, a bushing 19 provided inside the cylindrical filter body 2a is brought into sliding contact with the inner surface of the filter body 2a, and foreign matter adhering to the inner surface is more effectively removed by backwashing.

A sand filtration flow 75 with rougher grains is provided downstream of the sterilization means 3, and in addition to the filtration action of the filter element 2a, the filtration action of the sand filtration flow 75 removes water from the hot water. This allows approximately 100% of foreign substances to be filtered out. After the filtration process has been completed, the hot water is heated by the ceramic heater 4 as the reheating means 8, suppressing the drop in hot water temperature due to circulation, and heating the hot water as the hot water supply means 5! -) The temperature of the water supplied to the bathtub 1 is maintained. Such a ceramic heater 4 is energized approximately 24 hours a day. Such a ceramic heater 4 is nonflammable and highly safe. An ozone generating means 6 is provided downstream of the ceramic heater 4, and the generated ozone is sent to a pump (not shown) into the circulation path 13 to sterilize and decolorize with ozone. This is so that it can be done. Near the return port 12 of the bathtub 1, there is a bubble injection device 76 that sucks air by an ejector action as hot water passes and introduces air bubbles into the hot water, and a bubble injection device 76 that pressurizes air into the hot water. Microbubbles (
A fine bubble generator 77 that mixes (micron order) into hot water is placed side by side, and the flow path is switched by a switching valve 78 as a bubble switching means 9, so that either the bubble mixing device 76 or the fine bubble generator 77 is connected. By making it possible to mix air bubbles into the hot water, we create a jet bath state in which hot water mixed with normal-sized air bubbles is vigorously squirted inside the bathtub 1, and a jet bath state in which hot water mixed with normal-sized air bubbles is vigorously ejected from inside the bathtub 1, and a cloudy hot water mixed with fine air bubbles in the bathtub 1. It is designed to allow you to switch to a bubble bath state that sprays water inside your body.
