    • A whirlpool bath with an inverter-controlled circulating pump (P) comprises a bathtub body (1), a circulating pump (P) driven by a power-operated motor (M), a hot water circulation path (D) disposed between the bathtub body (1) and the circulating pump (P), the hot water circulation path (D) comprising a hot water suction path (10) and a hot water forced-feed path (11), the hot water forced-feed path (11) having at least one terminal end which is open into the bathtub body (1), at least one injection nozzle (3) which is mounted on the terminal end of the hot water forced-feed path (11), an air intake portion (5) connected to the hot water forced-feed path (11) to permit blowing of bubbling hot water into the bathtub body (1) from the injection nozzles (3), an inverter (E) interposed between a drive circuit (C) of the power-operated motor (M) of the circulating pump (P) and a power source and an electricity insulation means protecting the transfer of high frequency components of inverter-produced current to the hot water in the bathtub body (1). Due to such construction, the circulating pump (P) can be controlled such that the revolution of the motor (M) is readily and smoothly varied by way of a frequency modulation effected by the inverter (E) to provide the injection of hot water in various modes which are different in the injection amount and pressure of the injected hot water, while assuring a maximum degree of safety of a bather.
    • 具有逆变器控制的循环泵(P)的漩涡浴缸包括浴缸主体(1),由动力马达(M)驱动的循环泵(P),设置在浴缸之间的热水循环路径(D) 主体(1)和循环泵(P),包括热水吸入路径(10)和热水供给路径(11)的热水循环路径(D),热水供给路径(11) )具有至少一个开口到所述浴缸主体(1)中的终端,至少一个安装在所述热水强制供给路径(11)的终端上的喷嘴(3),进气部分 5)连接到热水强制供给路径(11),以允许从注射喷嘴(3)将发泡的热水吹入浴缸主体(1);逆变器(E)插入在 循环泵(P)的动力马达(M)和动力源以及保护逆变器的高频部件的传递的电绝缘装置 向浴缸体(1)的热水供给电流。 由于这种结构,可以控制循环泵(P),使得通过由逆变器(E)进行的频率调制容易且平滑地改变电动机(M)的旋转,以提供热水的注入 在注入热水的喷射量和压力方面不同的各种模式,同时确保沐浴者的最大程度的安全性。
