PROBLEM TO BE SOLVED: To solve the great difficulty of conventional bathtubs for children, the aged people, and those who have trouble in walking, etc. as the conventional bathtubs are when entering the bathtubs for taking a bath, the user mostly must enter by stepping over it, or the bottom of the bathtub is deeper than a floor level, or a lift is necessary to enter the bathtubs.SOLUTION: The conventional bathtubs are difficult for children, the aged people, and those who have trouble with their legs to step it over, to be lifted in it, or to step down into it. With a bathtub of the present invention, a user does not have to step over the bathtub, or step down to the bathtub bottom, and can take a bath even on a cart with casters safely and securely, as an opening/closing door, a lift, and a hot water supplying/discharging unit are provided. The bathtub becomes an ideal bathtub as it eliminates the trouble from the conventional lifting.COPYRIGHT: (C)2015,JPO&INPIT【課題】従来浴槽に入浴する時、大方の浴槽は跨いで入るか、床面より浴槽の底が深いものと、またリフトで吊つて入るものがある。これらは子供、老人、足の障害者等大変困難をきたしていた。【解決手段】従来の浴槽は子供、老人、足の障害者等には跨いだり、吊つたり、深みに入る事が困難であつた。今回発明の浴槽には開閉扉と昇降リフトと吸排貯湯機を設けたことにより跨がず、深みに入らず、駒付き台車でも楽に安全に安心して入浴できこれまでのリフト吊りの面倒も解消できて理想的な浴槽になつた。【選択図】図1
