PURPOSE:To prevent scale and slimy matter, etc., from adhering to a bathtub and a bathroom by diffusing ozone air generated by an ozone generator through a foam generator arranged in the water, and bringing the diffused ozone foam into contact with a washing object to be sterilized, immersed into the water. CONSTITUTION:In the case this device is applied to a bathtub 10, ozone air generated by an ozone generator 12 is diffused into hot water, and a foam generator 11 for allowing hot water and air to be subjected to vapor-liquid mixing is installed on a bottom part in the bathtub 10. As for the foam generator 11, a porous substance is utilized, and by allowing ozone air to pass therethrough, the ozone air is diffused into hot water as foam. Also, as for the ozone generator 12, a device which utilizes a theory of what is called air discharge, for instance, for allowing air to pass through in silent discharge by a high voltage, and varying a part of oxygen to ozone is used. In such a way, by bringing ozone air of minute foam into contact with the washing object to be sterilized, oxidation, bleaching, protein and oil/fat decomposition, and deodorization are contrived, and it is prevented that scale and slimy matter, etc., adhere to a bathtub. |
