Abstract: PURPOSE:To enable an efficient and positive heating and keeping high temperature to be carried out for bath water in a bath tub by a method wherein a bath water circulating, purifying and temperature keeping device is comprised of at least two heaters and a heater control means for keeping and heating for electrical energization of one of these heaters, controlling a fast concurrent heating of a plurality of heaters, monitoring a trouble of each of the heaters and performing a selective electrical energization control for a normal heater. CONSTITUTION:In the event that the first heater 7A is not normally operated, the second heater 7B is turned ON, i.e. the second heater is electrically energized. Bath water 2 in a bath tub 1 is automatically kept at its temperature and heated to keep a predetermined temperature under a controlling operation of a controller 14 for turning OFF the first heater 7A. In the event that a temperature of the bath water is lower than its set temperature by 5 deg.C or more, the bath water 2 in the bath tub 1 is rapidly heated up to its predetermined temperature under a controlling operation of the controller 14 for turning ON the first and second heaters 7A and 7B.

Abstract: PURPOSE:To improve the purifying capacity of the device by sucking up bathwater in a bathtub through a suction pipe, filtering the bathwater by the plural filters provided to the suction pipe and further filtering the bathwater by a main filter in a bathwater purifying unit. CONSTITUTION:The bathwater in a bathtub 1 is sucked up by a circulating pump 3 through a suction pipe 4, filtered by a filter 5 and returned to the bathtub 1 through a discharge pipe 6 by this bathwater purifying unit. A second filter 11 having coarser mesh than a main filter 5 is provided to the middle of the suction pipe 4 in the bathtub 1, and a third filter 12 having a coarser mesh than the filter 11 is furnished at the suction part of the suction pipe 4 in the bathtub 1. The bathwater in the bathtub 1 is sucked up by the circulating pump 3 through the filters 12 and 11. Consequently, the purifying capacity is enhanced, and the main filter is used for a long period.

Abstract: PURPOSE:To rapidly and surely purify bathwater in a bathtub by repeatedly lifting the suction port of a suction pipe up and down, uniformly sucking the bathwater from the lower position to the upper position, circulating and purifying the bathwater. CONSTITUTION:The bathwater in a bathtub 1 is sucked up by a circulating pump 3 through a suction pipe 4, filtered by filters 5 and 6, heated by a heater 7 and returned to the bathtub 1 through a discharge pipe 8. A lifting mechanism 11 for lifting the suction port 4A of the suction pipe 4 up and down and its driving mechanism 12 are provided. Consequently, the bathwater in a bathtub is rapidly and surely purified.

Abstract: PURPOSE:To easily exchange second filter devices by providing the second filter device to a sucking pipe so that the filter device is in the bath water of the bath tank and can freely be attached and detached. CONSTITUTION:The bath water 2 in the bath tank 1 is pumped with a circulating pump 21 through a sucking pipe 25, filtered through a first filter device 5 and returned through an ejection pipe 26 to the tank 1. In this process, a second filter device 7 is provided to the sucking pipe 25 in the bath water 2 so that the filter device 7 can freely be attached and detached. By this method, exchange of the second filter devices 7 can easily be performed and the first filter device 5 can be used for a long time.

Abstract: PURPOSE:To maintain the high purifying capacity over a long period by supplying the bathwater sucked up by a circulating pump to a purifying passage for discharging water for cleaning a granular filter through a passage switching valve. CONSTITUTION:The bathwater in a bathtub 1 is sucked up by a circulating pump 4 through a suction pipe 3, filtered by a granular filter 6, heated by a heater 7 and returned to the bathtub 1 through a discharge pipe 8 by this bathwater purifying unit. A passage switching valve 12 is provided to the passage for supplying the bathwater sucked up by the pump 4 to the inlet 15 of the filter 6, and a cleaning passage 23 is provided to discharge the inside cleaning water from the side wall 21 of the housing 17 for the filter 6. The bathwater sucked up by the pump 4 is supplied to the cleaning passage 23 through the switching valve 12. Consequently, the high purifying capacity of the device is maintained over a long period.

Abstract: PURPOSE:To prevent the intrusion of the broken pieces of a filter member into the bathwater in a bathtub by providing a horizontal passage with the downstream side closed to the return passage of bathwater, branching a discharge pipe from the middle and bending the downstream side of the horizontal passage downward to form a trap. CONSTITUTION:The bathwater in a bathtub 1 is sucked up by a circulating pump 4 through a suction pipe 3, filtered by a filter 5 and returned to the bathtub 1 through a discharge pipe 6 by this bathwater circulating and purifying unit. In this case, a horizontal passage 7 with the downstream side closed is provided to the return passage for the bathwater delivered from the filter 5. The discharge pipe 6 is branched from the middle of the horizontal passage 7, and the downstream side of the passage 7 is bent downward to form a trap 8. Consequently, the broken pieces of the filter member, etc., are not intruded into the bathwater in the bathtub.

Abstract: PURPOSE:To prevent the forgetting of measuring time from occurring by attaching a clock function with alarm settable plural alarm times at a blood pressure measuring function. CONSTITUTION:A tonometer 1 functions as a clock with alarm ordinarily, and the present time is displayed on a display part 5 by controlling the display part 5 with a clock and alarm function control part 13. When (0) is displayed on the display part 5 and a control part 12 is set at a standby state, a user sets a pressurizing value higher than its own maximum blood pressure value with a switch 7, and when the depressing operation of a switch 10 is performed after winding an arm belt 3 on an arm, the control part 12 sends the air from an air tube 19 in a main body 2 to the arm belt 3 by driving a pressurizing motor 14, and the internal pressure of the arm belt 3 is increased to the pressurizing value set with the switch 7. When the internal pressure of the arm belt 3 shows a preset pressurizing value, the control part 12 stops the pressurizing motor 14, and exhausts the air in the arm belt 3 gradually, thereby, the internal pressure of the arm belt 3 can be reduced. The control part 12 detects the number of pulsation with a pressure sensor 15 during performing the pressurization and the pressure reduction of the arm belt 3, and the maximum and minimum blood pressure values are measured and displayed. Thereby, the forgetting of the measuring time by the user can be prevented from ocurring.
