As shown in FIG. 2, the operating environment setting section 22 operates a start / stop key 23 for operating / stopping the apparatus, and operates the bubble generation device 10 to generate air bubbles for jetting a water flow containing air bubbles into the bathtub. It comprises a generation key 24, a bath key 25 for stopping generation of ozone at the time of bathing, and a pattern selection key 26 as a pattern selection means for selecting a bathing pattern described later. The driving environment set and selected by these keys is displayed on the driving environment display device 7.

The driving environment display device 7 is provided with a plurality of LEDs as shown in FIG. 2, and displays the driving environment set and selected by each key of the driving environment setting section 22 by lighting.

In this embodiment, four types of bathing patterns that can be selected are bathing time zone type bathing patterns indicated by P1 to P4 in the display section of FIG. When the operation is started and the pattern selection key 26 is not operated, the bathing patterns P1 to P4 are not initially selected, and
The pattern selection in which the bath time is 4 hours is automatically selected, and each time the pattern selection key is pressed, P1, P2, P3,
The bath pattern is selected in the order of P4, then the 24-hour bathing pattern described above is selected, and the bathing pattern from P1 is cyclically selected again.

Further, the control unit 1 is connected to a bath water temperature detecting device 3 for detecting a bath water temperature and a clock device 4.
The detected hot water temperature value is displayed on the bath water temperature display device 6, and the time measured by the clock device is displayed on the time display device 5.

Further, a circulating pump 8 for circulating bath water and a warming heater 9 are connected to the control unit 1. The control unit 1 controls the circulating pump and controls bath water temperature data from the bath water temperature detecting device 3. Is compared with a heat retention temperature set value described later and a standby temperature described later, and the energization control of the heat retention heater 9 is performed.

Further, the control unit 1 is connected to a first memory ROM and a readable / writable second memory RAM as pattern data storage means for retaining the stored contents even when the power is turned off. The first memory ROM stores a plurality of bath pattern data. The bathing pattern is, as shown in FIG. 3, a pattern of a bathing time zone, a heat retention temperature thereof, and a temperature in a standby state excluding the bathing time zone.

In FIG. 3, the temperature at the time of standby is set to a certain temperature, for example, 5 ° C. lower than the heat retention temperature in the bathing time zone, or is set to a certain temperature in advance. When a bathing pattern is selected by operating the pattern selection key 26, the selected bathing pattern data is read from the first memory ROM and registered in the second memory RAM.

In the present embodiment, the types of bathing patterns that can be selected as described above are four types of bathing time zone type bathing patterns indicated by P1 to P4 on the display unit of FIG. 2 and one type of 24-hour type bathing pattern. , But the number can be increased as necessary.

S1 to S3 When a bathing pattern is selected by operating the pattern selection key 26 of the driving environment setting section 22 in S1, the bathing pattern data selected in S2 is read out from the first memory ROM, and the second bathing pattern data is read out. One of the LEDs 14 corresponding to the bathing pattern selected as shown in FIG. 2 is turned on in S3 as shown in FIG.

S4 to S6 When the bathing pattern is selected, the time of the clock device 4 is read in S4, and it is determined in S5 whether the circulation pump 8 is operating. If the circulating pump 8 is in operation, the process proceeds to S7; otherwise, the process proceeds to S6, in which the heat retaining heater 9 is turned off and the process returns to S4.

S7 The selected bathing pattern data is read from the second memory RAM. The bathing pattern data is, as described above, data of a bathing time zone, its heat retaining temperature, and a pattern of a temperature during standby excluding the bathing time zone.

S8 It is determined whether the time is within the bathing control time zone. The bathing control time period is a time period from a time that is a predetermined time before the start time of the bathing time period to the end time of the bathing time period. This is because it takes a certain amount of time to raise the temperature of the bath water from the temperature at the time of standby to the temperature at the time of bathing, because the heater 9 is not for reheating but for heating. If it is within the bathing control time zone, the process proceeds to S9, and if not, the process proceeds to S10.

In step S9, the bath water is raised to the heat holding temperature and compared with the bath water temperature data from the bath water temperature detecting device 3 based on the heat holding temperature data of the selected bathing pattern data. 9 is energized.
