    摘要： A whirlpool bath with an inverter-controlled circulating pump comprises a bathtub body, a circulating pump driven by a power-operated motor, a hot water circulation path disposed between the bathtub body and the circulating pump, the hot water circulation path comprising a hot water suction path and a hot water forced-feed path, the hot water forced-feed path having at least one terminal end which communicates with the interior of the bathtub body, at least one blow-off nozzle which is mounted on the terminal end of the hot water forced-feed path, an air intake portion connected to the hot water forced-feed path to permit blowing of bubbling hot water into the bathtub body from the blow-off nozzles, an inverter interposed between a drive circuit of the power-operated motor of the circulating pump and a power source and an electrical insulation means protecting the transfer of high frequency components of inverter-produced current to the hot water in the bathtub body. Due to such construction, the circulating pump can be controlled such that the revolution of the motor is readily and smoothly varied by way of a frequency modulation influenced by the inverter to provide the blow-off of hot water in various modes which are different in the blow-off amount and pressure of the blow-off hot water, while assuring a maximum degree of safety of a bather.

    摘要翻译： 具有逆变器控制的循环泵的漩涡浴缸包括浴缸体，由动力马达驱动的循环泵，设置在浴缸主体和循环泵之间的热水循环路径，热水循环路径包括热水 吸入路径和热水强制供给路径，所述热水供给路径具有至少一个与所述浴缸主体的内部连通的终端，至少一个安装在所述浴缸的末端的吹出喷嘴 热水强制供给路径，连接到热水强制供给路径的进气部分，以允许从吹出喷嘴吹入发泡的热水进入浴缸体;逆变器，其插入在动力操作的驱动电路 循环泵的电动机和电源以及保护逆变器产生的电流的高频部件向浴缸体内的热水的转移的电绝缘装置。 由于这样的结构，可以控制循环泵，使得通过受到逆变器影响的频率调制容易且平滑地改变电动机的转速，以便以各种不同的模式提供热水的吹扫 吹出热水的排出量和压力，同时确保沐浴者的最大程度的安全性。

    摘要： A flow rate control valve includes a second substrate having a flexible thin film and interposed between a first substrate having a heating mechanism and a third substrate having a sealing section. The first substrate and the second substrate close an internal space formed adjacent to the heating mechanism and filled with an expandable material. The sealing section and the flexible thin film function together as a valve. The heating mechanism heats and expands the expandable material whose pressure is detected by pressure-detecting sensors. The detected pressure value is fed back to a control mechanism of the heating mechanism for opening/closing a fluid flow passage and controlling the valve opening degree.
