However, there are some bathtub forced vibrators that have an air intake part in the middle. With this configuration, the circulation pump sucks the bathwater in the bathtub body through the bathwater suction pipe, and the circulation pump causes the bathwater to flow through the bathwater delivery pipe and squirts it into the bathtub body from the discharge part of the pipe. At this time, the air intake is mixed with the air taken in by using the negative pressure caused by the hot water jetting out from the air intake part, so that the hot water mixed with bubbles can be jetted out. ing. In addition, the bubble-generating bathtub having the above-mentioned basic configuration is equipped with an automatic control valve that automatically adjusts the amount of air intake in the middle of the air intake pipe connected to the air intake section. By adjusting the amount of air intake with a valve and adjusting the strength of the ejection pressure of the bubble-mixed bath water, it is possible to enjoy a jet stream with a desired ejection pressure.

[Explanation of your favorite jet mode]

Below are the jet modes of your choice (mild blow,
For acupressure blow, pulse blow, pine surge blow, wave blow and air pulse blow), Fig. 13~
This will be explained based on FIG. 17. [1] Mild Blow Mild blow is a type of jet flow in which the amount of hot water jetted from each spout nozzle (2), (3), and (4) is large and the jetting pressure is low. Wrap it up,
It gives the bather the sensation of a stimulating pine surge. In other words, the mild blow is performed by each jet nozzle (2) (3).
) and (4) are fully opened, and the rotation speed of the circulation pump (P) is kept within a certain range (for example, 2
100 to 300Or, p, Set the strength level of each jet nozzle (2
) (3) (4) Larger amount of bath water (e.g. 40-801

) (N4) is the rotation speed performance curve of the circulation pump (P). However, the magnitude relationship of the rotation speed is 81>N2>N3>
It is N4. In addition, the ejection amount-ejection pressure characteristic curve (Fl) in Fig. 13a
Point (b) on the top indicates that the rotation speed of the circulation pump (P) is around the maximum (N1) (for example, 300 Or, l), Ill
) shows the state of mild blow. Further, in FIG. 13a, (Yl) indicates a mild blow zone, and points (bl) (b2) indicate a mild blow state set within the mild zone (Yl). Furthermore, FIG. 14 shows examples of jet nozzle characteristic curves R1, R2, and R3 when the jet Jl adjustment valve body (22) is fully opened, half opened, and quarter opened. Ul,
υ2. υ3... is the ejection pressure line. However, the magnitude relationship of the ejection pressure is υ1<U2<tJ3... Further, point (b) in FIG. 13a can be represented by point (1)') on the jet nozzle characteristic curve (R1) shown in FIG. 14a. In addition, in Fig. 14a, (Y'1) indicates the mild blow zone in the jet nozzle characteristics, and the point (b'1)
)(b'2) indicates a mild blow state set within the same mild blow zone (Y'1). The mild blow mentioned above can be performed using the remote controller (3
0) is activated by turning on the mild blow switch (61). Moreover, the usage pattern of the jet nozzles for spouting such mild blow bath water is to turn on the jet nozzle all usage pattern switch (72), and turn on the six all jet nozzles (2).
(2) (3) (3) (4) When spouting bath water at the same time from (4), and when turning on the circulation use pattern switch (73), from each spout nozzle (2), (3), and (4). In the case where bath water is spouted alternately at a cycle of X1 seconds (for example, 3 seconds), when one or two types of each spout nozzle (2), (3), and (4) are selected, bath water is emitted from the spout nozzle translated into may erupt. In addition, when using a mild blow, the bubble volume control valve (5d) of the air intake section (5) can be controlled using the remote controller (30).
The air bubble amount increase/decrease switch (66067) is operated to adjust the amount of air bubbles, so that the mildness applied to the body of the bather can be varied. Further, the speed of switching each switch when changing the strength level of the mild blow or changing the jet nozzle usage pattern is approximately 1 nm/sec. Furthermore, the bubble volume increase/decrease switches (66) and (67) are also switched within one second. [2] Shiatsu Blow Shiatsu Blow is a jet style in which the amount of hot water spouted from each spout nozzle (2), (3), and (4) is small and the jet pressure is high, and it powerfully hits a part of the bather's body. By applying the jet stream, the bather is given a stimulating pine surge sensation with acupressure sensation. In other words, the acupressure blow is performed so that the discharge pressure of the circulation pump (P) is constant (for example, 1.0 kIr/cl).
Rotate the same pump (P) to the highest rotational speed (Nl) (for example, 3
The operation is controlled near 000r, p, n), and each jet nozzle (
2) Adjust the spout amount regulating valve body (22) in (3) and (4) to keep the spout amount of bath water within a certain small range (for example, 30
~50 J/n+in) and can be set in several stages (for example, five stages). In addition, the point (e) on the jetting amount-spouting pressure characteristic curve (R3) in FIG.
The figure shows the state of acupressure blow when the condition is J/ll1n). In addition, in Fig. 13a, (Y2) indicates the acupressure blow zone in the ejection amount-ejection pressure characteristic, and the point (el) (
e2) indicates the acupressure blow state set within the same acupressure blow zone (Y2). Further, point (e) in FIG. 13a can be represented as a point (eo) on the jet nozzle characteristic curve (R3) shown in FIG. 14a. In addition, in Fig. 14a, (Y'2) indicates the acupressure blow zone in the jet nozzle characteristics, and point (e'1) (
e'2) indicates the acupressure blow state set within the same acupressure blow zone (Y'2). The above-mentioned shiatsu blow is a remote control (30)
It is activated by turning on the acupressure blow switch (62). Moreover, the usage pattern of the jet nozzles for spouting bath water in such a shiatsu blow state is to turn on the all jet nozzle usage pattern switch (72), and then turn on the four jet nozzles (2).
(2) (4) From (4), when the bath is ejected at the same time and the circulation use pattern switch (73) is turned on,
There is a case where bath water is alternately spouted from each spout nozzle (2) and (4) at a cycle of
2) One or both of (3) and (4) may be selected and bath water may be spouted from the selected spout nozzles. Further, the speed of switching each switch when changing the level of acupressure blowing or changing the pattern of use of the jet nozzle is approximately 1 stroke/second. In addition, when using acupressure blow, the air bubble amount can be adjusted by operating the air bubble amount adjustment valve (5d) of the air intake part (5) with the air bubble amount increase/decrease switch (66) (67) of the remote controller (30). This makes it possible to vary the sensation of acupressure applied to the bather's body. At this time, the switching operation by the bubble volume increase/decrease adjustment switches (66) and (67) moves the bubble volume control valve (5d) to the maximum speed (
For example, this can be done by moving at a speed of less than 1/sec). [3] Pulse blow Pulse blow is a jet type in which the individual jet nozzles (2) and (4) are periodically opened and closed to alternately spout and stop the bath water, and the jet is emitted and emitted in pulses. It can give a sharp stimulus to the bather depending on whether it is absent or not. That is, in the pulse blow, in the acupressure blow,
Valve body (22) for adjusting the jetting amount of each jetting nozzle (2) (4)
is moved alternately between a fully open position and a fully closed position at maximum speed (for example, within 1 speed/second) every predetermined time period. As a result, as shown in FIGS. 15a and 15b, a state (Pl) in which bath water is spouted and a state y1 (P2) in which no bath water is spouted can be alternately generated. Note that when ejecting the bath, there are cases in which bubbles are included and cases in which bubbles are not included. FIG. 16 shows the relationship between the amount of hot water spouted and the spouted time when the hot water spouting time and the hot water spouting stop time of pulse blowing are the same (tl) seconds. Then, by changing the strength level of the pulse blow, the amount of hot water jetted out is within a certain range (for example, 30 to 5 (LD /
ll1n) in several stages (for example, five stages). In addition, such pulse blow can be controlled by the remote controller (
It is activated by turning on the pulse blow switch (79) (30). Moreover, the usage pattern of the jet nozzles for spouting such pulse-blown bath water is to turn on the all jet nozzle usage pattern switch (72), and then turn on the four jet nozzles (2) (2).
) (4) When the bath water is spouted out from (4) at the same time, and when the circulation usage pattern switch (73) is turned on, each spout nozzle (2) and (4) are alternately spouted at a cycle of X3 seconds (for example, 3 seconds). When spouting bath water, each spout nozzle (2) (3
) (4) One or two types may be selected and bath water may be ejected from the selected ejection nozzles. In addition, the speed of switching each switch when changing the pulse blow level or the jet nozzle usage pattern is approximately I
InI/sec. In addition, when using a pulse blow, the opening/closing cycle of the valve body (22) for adjusting the jetting amount of each jetting nozzle is controlled by the period increase/decrease switch (70) (71) of the remote controller (30).
), it is possible to change the acupressure sensation given to the bather. The opening/closing cycle of the jet m regulating valve body (22) can be set in five stages, for example, 1 second, 2 seconds, 3 seconds, 4 seconds, and 5 seconds. [4] Matsu Surge Blow Matsu Surge Blow is a jet flow type in which the above-mentioned mild blow and acupressure blow are performed alternately by periodically changing the spout amount and jet pressure of bath water from each spout nozzle (2) and (4). It alternately gives the bather the mildness of a mild blow and the sensation of shiatsu massage. That is, in the pine surge blow, the air bubble amount control valve (5d) of the air intake part (5) is fully opened, and the circulation pump (
While maintaining the rotation speed of P) constant, each jet nozzle (2) (
3) Gradually decrease or expand the opening degree of the spout amount regulating valve body (22) in (4) to increase or decrease the spout amount of bath water from each spout nozzle (for example, 30 to 80 J/1g1n)
and changes in the strength of ejection pressure (e.g. 0.3 to 1.0 h/c
i) is performed periodically. The strength level of the pine surge blow can be changed by setting the increase/decrease in the amount of bath water spouted in several stages (for example, five stages). Further, (cl) and (c2) shown in Fig. 13b are the characteristic curves of the Pine Surge Blow that change between the jetting amount and jetting pressure characteristic curves (Fl) and (F3), respectively, along the rotational speed performance curve, and each characteristic The amount and pressure of hot water jetted from each jetting nozzle change periodically along the curves (cl) and (c2), producing a mild effect and an acupressure effect. In addition, the pine surge blow characteristic curve ((t
) (C2) can be expressed as curves (c'1) (c'2) in the jet nozzle characteristics shown in Fig. 14b;
)(c'2), the amount of bubbles changes significantly, and this change in the amount of bubbles enhances the pine surge effect on bathers. The pine surge blow is performed by turning the pine surge blow switch (64) of the remote controller (30) on.
It is activated by turning it to N. Moreover, the usage pattern of the spout nozzles for spouting the bath water of the Pine Surge Blow is such that the usage pattern for all spout nozzles (72) is turned on and the four spout nozzles (2) (
204) When the bath water is spouted from (4) at the same time, and when the circulation usage pattern switch (73) is turned on, the bath water is spouted alternately from each spout nozzle (2) and (4) at a cycle of X4 seconds (for example, 3 seconds). When spouting hot water, each spout nozzle (2) (3
) (4) One or two types may be selected and bath water may be ejected from the selected ejection nozzles. In addition, the speed of switching each switch when changing the level of pine surge blow or changing the jet nozzle usage pattern is
Approximately 1 city/second. Also, when using Pine Surge Blow, each jet nozzle (2
) (3) The opening/closing operation cycle of the jet volume regulating valve body (22) in (4) is adjusted by the cycle increase/decrease switch (70) (71) of the remote controller (30), and the finger pressure is applied to the bather. This makes it possible to vary the effect. The opening/closing cycle of the ejection amount regulating valve body (22) can be set in five stages, for example, 1 second, 2 seconds, 3 seconds, 4 seconds, and 5 seconds. Further, the alternating bath water spout period from the foot side spout nozzle (2) and the back side spout nozzle (4) described above may be set to -half of the opening/closing operation period of the spout amount regulating valve body (22). can. [5] Wave blow Wave blow is a jet flow type in which the rotation speed of the circulation bong 1 (P) is periodically changed to periodically change the strength and weakness of the ejection pressure of bath water, and the ejection amount is slowed down. By making the flow stronger and weaker in cycles, it creates an unsteady flow, giving the bather a jet of water that resembles a wave that approaches and returns to the bather. In other words, the wave blow is performed by each jet nozzle (2H3).
Turn on/off the operation of the circulation bong 1 (P) by setting each of the injection amount adjusting valve bodies (22) in (4) to a fully open or slightly open state.
or the rotation speed of the circulation pump (P) is periodically changed within a certain range (for example, within the range of 1500 to 3000r, p, ti). And, changing the strength level of the wave blow,
In addition to changing the flow rate, the air bubble amount control valve (5d) of the air intake part (5)
), and the larger the amount of bubbles, the stronger the ejection pressure can be. In addition, by changing the strength of the wave blow, for example, you can enjoy a comfortable blow in time with the rhythm of music. In other words, the strength of the rhythm is converted into the strength of the voltage, the frequency of the inverter output is converted in accordance with the same voltage, the rotation speed of the pump drive motor (M) is changed, and the changes in the strength of the wave blow are converted into the rhythm of the music. It can be adjusted to In addition, (dl) (d2) (d3) shown in FIG. 13c are
Each of these is a wave blow jet amount-spout pressure characteristic curve, and the jet amount and jet pressure of bath water change along each curve (dl), (62), and (d3). Also, (d'1) (cl'2) (d'
3) are jet nozzle characteristic curves for wave blowing, and wave blowing allows the amount of bubbles to be changed significantly. Mata, Wave Blow is a remote controller (30
) is activated by turning on the wave blow switch (65). Moreover, the usage pattern of the jet nozzles that spout bath water in such a wave blow state is such that the all jet nozzle usage pattern switch (72) is turned ON, and six all jet nozzles (2) (2) (3) (3) are used. ) (4) From (4), when the bath water is spouted out at the same time, and when the circulation usage pattern switch (
73), turn on X5 from each jet nozzle (2) and (4).
When bath water is spouted alternately at a cycle of seconds (for example, 3 seconds), and when one or two types of each spout nozzle (2), (3), and (4) are selected, the bath water is spouted by the selected spout nozzle. There are cases. Further, the switching speed of each switch when changing the wave blow level or the jet nozzle usage pattern is approximately 1/sec. In addition, when using the wave blow, the cycle for changing the rotation speed of the circulation pump (P) can be controlled using a remote controller (30
) can be adjusted by cycle increase/decrease switches (70) and (71) to vary the acupressure effect given to the bather. The opening/closing cycle of the jet i regulating valve body (22) can be set in five stages, for example, 2 seconds, 3 seconds, 4 seconds, 6 seconds, and 8 seconds. Moreover, the waveform curve (P5) shown in FIG. 17 shows the relationship between the bath water spout amount and the bath water spout time of the above-mentioned wave blow blowing out at a fixed period. Further, the cycle in the above-described circulation usage pattern can be made to match the cycle in which the rotation speed of the circulation bong 1 (P) changes. [6] Air pulse blow The air pulse blow periodically changes the air intake time and air intake stop time by the air intake section (5) to separate bath water with bubbles and bath water without bubbles. It is a jet style in which the jets are ejected alternately, and provides a different stimulus to the bather than the pulse blow described above. That is, in the air pulse blow, in the above-mentioned acupressure blow, the air bubble amount control valve (5d) of the air intake part (5) is alternately and repeatedly operated at a constant cycle (for example, within 1 nun/sec) between fully open operation and fully open operation. According to Figures 18a and 18b
As shown in the figure, bath water mixed with bubbles (p3) and bath water without bubbles (p4) can be jetted out alternately. Moreover, FIG. 19 shows the relationship between the amount of bubbles and the blowing time when the bubble blowing time and the bubble blowing stop time of the air pulse blow are the same (t2) seconds. By changing the intensity level of the air pulse blow, the amount of hot water jetted out is within a certain range (for example, 30~50J).
/iin) in several stages (for example, five stages). In addition, such air pulse blow can be performed by turning on the air pulse blow switch (63) of the remote controller (30).
It is activated by Moreover, the usage pattern of the jet nozzles for spouting the bath water of air pulse blowing is such that the pattern switch (72) for using all jet nozzles is turned on, and the four jet nozzles (2) are used.
(2) (4) When simultaneously spouting bath water from (4), turn on the circulation pattern switch (73), and from each spout nozzle (2) (4) for X6 seconds (for example, 3 seconds)
There are cases in which bath water is jetted out alternately in a period of , and cases in which one or two types of each jet nozzle (2), (3), and (4) are selected and bath water is jetted out from the selected jet nozzles. Further, the speed of each switch/on switch when changing the level of air pulse blow or changing the pattern of use of the jet nozzle is approximately 1/sec. In addition, when using pulse blowing, the opening/closing cycle of the bubble volume control valve (5d) of the air intake part (5) can be controlled by switching the cycle increase/decrease switch (70) (7) using the remote controller (30).
1), it is possible to vary the stimulation given to the bather. And the opening/closing operation cycle of the bubble amount control valve (5d) is as follows:
For example, it can be set in five stages: 1 second, 2 seconds, 3 seconds, 4 seconds, and 5 seconds.

[Explanation of operation of bubble generating bathtub]

Below, the operation of the above-mentioned bubble generating bathtub (A) will be described in 20a.
The explanation will be based on the control sequences shown in Figs. 20f and 21. First, a plug for the control unit (C) etc. is inserted into the power source and power is supplied (100). Next, a freeze prevention operation is performed (110). That is, in the freeze prevention operation, as shown in FIG.
If the temperature of the bath water is lower than the temperature at which the circulation pump (P) can be used normally (e.g. 5°C), the circulation pump (P) is operated at low speed by inverter control112). After the bath water is brought to a temperature that allows normal use by circulating the bath water (113Y), the controlled operation of the circulation pump (P) is stopped (114), and the process proceeds to the next step (120). Also, while the circulation pump (P) is operating at low speed, check whether the water level of the bath water in the bathtub body (1) is above a certain level (115), and if the water level is not above a certain level (115).
115N), stop the operation of the circulation pump (P) (1
14). In addition, the temperature of the bath water in the bathtub body (1) is controlled by the circulation pump (P
) is higher than the normal usable temperature, the process proceeds to the next step (120) in normal mode. Then, turn on the operation switch (60) provided on the remote controller (30) 6 (120). In this case, if the bath water temperature condition described above (5°C or higher) is not met, even if the operation switch (60) is turned on,
Each drive is inoperative. Next, the pressure sensor (48), which also serves as a water level sensor, detects that the water level of the bath water in the bathtub body (1) is above a certain level, that is, the water level is higher than each spout nozzle installation position, and that the water level is higher than each spout nozzle. It is detected whether the water level is higher than the water level at which the bath water can be spouted in the mode (121). As a result, if the water level is above a certain level (121Y)
, the operation lamp (60a) lights up (122), but if the water level is not above a certain level (121N), the abnormality lamp (not shown) flashes (123). The hot water operation starts (124), and this hot water operation starts when the bathtub body (1
) is refilled with bath water to bring the water level of the bath water above the above-mentioned certain level. When the water level reaches a certain level, the hot water operation will stop and the operation lamp (6) will stop.
0a) lights up (122), then all jet nozzles (2)
(3) (4)? &! Whether or not the L adjustment valve element (22) and the air bubble amount adjustment valve (87) are at the preset position is detected by the valve element opening/closing degree detection sensor (23f) (91') (125). Here, the preset position means, for example, all jet nozzles (
2) With the valve bodies (22) in (3) and (4) fully open, bath water is spouted at a constant jetting amount and jetting pressure from all jetting nozzles (2), (3), and (4). This is a position where it is possible to If the detection result is the preset position, the desired jet mode can be selected. Also, if the detection result is that it is not the preset position, (1
25N), and move the jetting amount adjusting valve bodies (22) and bubble amount adjusting valves (87) of all jetting nozzles (2, 3, and 4) to the grisset position (126). And, you can set your favorite jet mode using the remote controller (
Turn on the mild plow switch (61) provided at 30).
(127Y), select mild plow operation (12g) or turn the shiatsu plow switch (62) to O.
By pressing N (129Y), select the acupressure plow operation (130) or turn the pulse plow switch (63) to O.
By pressing N (131Y), select air pulse plow operation (132) or press the pine surge plow switch (
64) to select the pine surge plow operation (133Y), or by turning on the wave plow switch (65) (135Y) to select the wave plow operation (13G), or to select the air plow operation (13G). By turning on the pulse plow switch (79) (1
3? aY) Select pulse plow operation (?32a
). The case where mild blow operation is selected (128) will be described below. When one of the above RA modes is selected, it is checked again whether the water level of the bath water in the bathtub body (1) is above a certain level (137). This is because the bath water in the bathtub body (1) may be pumped out before the favorite jet mode is selected, and the water level may not be maintained above a certain level. If the water level is not above a certain level, the abnormal lamp will blink (138) If the bath is equipped with an automatic hot water heater, the hot water operation will start (139), and the bathtub body (
1) Raise the water level of the bathtub above a certain level. Next, when the water level is detected above a certain level,
Control operation of the circulation pump (P) begins (140.1) Then, the discharge pressure of the circulation pump (P) is detected by the pressure sensor (48).
Detects the above and checks whether the discharge pressure is normal (141). If the above discharge pressure is abnormal (141N), the abnormality rung is blinked (+142), and the operation of the circulation pump (P) is stopped (143). ). Additionally, if the discharge pressure is normal (141Y), the driving time setting timer of the circulation pump (P) is automatically turned on (
144). By setting the driving time of the circulation pump (P) in advance (for example, 30 minutes), you can forget to turn the operation switch (60) to 0FFL and run the circulation pump (P) for a long time.
This prevents the problem of causing the motor to drive. Next, the jet operation mode lamp lights up (145) This is to light up the lamp of the previously selected favorite jet flow mode so that the user can visually confirm which mode has been selected. . Next, the amount of bubbles is adjusted to increase or decrease as needed based on the preset amount. That is, if neither of the bubble volume increase/decrease switches (66067) of the remote controller (30) is turned ON, the bubble volume control valve (87) is kept at the preset position (146Y), and a certain amount of bubbles is mixed with the bath water. It is ejected (147). Moreover, in the case of mild blow operation, step (14)
In b), the preset amount is set in advance so that a form of jet flow with a large amount of hot water jetted out and a low jetting pressure can be taken. Also, a bubble volume increase switch (61) that increases the volume of bubbles.
If you continue ONL (148Y), the amount of bubbles will increase.Also, turn the bubble amount reduction switch (66) to O to decrease the amount of bubbles.
If NL continues (151Y), the amount of bubbles decreases. After setting the amount of bubbles as described above, the discharge pressure of the circulation pump (P) and the water level of the bath water in the bathtub body (1) are measured again by the pressure sensor (48). ), the rotation speed of the circulation pump (P) is detected by the rotation speed detection sensor (6), and it is checked whether it is normal (15.1) and if there is an abnormality,
Flash the error lamp (155) and turn on the circulation pump (P).
(156) Further, the operation of the circulation pump (P
Check the discharge pressure and rotation speed of the circulation pump (P) (157), and control the discharge pressure and rotation speed of the circulation pump (P) by causing the control section (C) to perform feedback control according to the deviation from the set value (140). If the deviation is within the setting range (157Y), the bubble amount setting lamps (66a) (67a), the bath water spout cycle setting lamps (70a) (71a), and the bath water jet strength setting lamps (68a) (69a) are displayed. The lamp is lit (158). By lighting the lamp, the user can visually check the usage status. In this state, a desired usage pattern for each of the jet nozzles (2) (304) can be selected by turning on the changeover switch. In other words, the preset pattern is a pattern in which all the jet nozzles (2N304) are used.
If neither switch is turned on (159Y)
(161N), bath water in the preset jet mode is spouted from all jet nozzles (2), (3), and (4) (16
0). Then, when the circulation use pattern switch (73) is turned on (161Y), the bath water in the set jet mode is sequentially ejected from each of the ejection nozzles (2), (3), and (4) according to the circulation use pattern (162). Further, when the cyclic usage pattern switch (73) is turned off (163Y), the pattern returns to the preset pattern. Furthermore, when the back side jet nozzle usage pattern switch (74) is turned on (164Y), bath water in the set jet mode is jetted from each jet nozzle (3) (3) according to the back side jet nozzle usage pattern (165). , and when the dorsal jet nozzle usage pattern switch (74) is turned off (1
66Y), return to preset pattern. In addition, the foot fllf jet nozzle usage pattern switch (7
5) is turned ON (167Y), bath water in the set jet mode is spouted from each jet nozzle (2) (2) according to the foot-side jet nozzle usage pattern (168), and the foot-side jet nozzle usage pattern switch When (75) is turned off (169Y), the pattern returns to the preset pattern. Furthermore, when the ventral jet nozzle usage pattern switch (76) is turned on (170Y), bath water in the set jet mode is spouted from each jet nozzle (4) (4) according to the ventral jet nozzle usage pattern (171). . Also, when the ventral jet nozzle usage pattern switch (76) is turned off (17
2Y), return to preset pattern. Also, turn on the dorsal jet nozzle usage pattern switch (74) and the foot jet nozzle usage pattern switch (75).
Then (173Y), each jet nozzle (2) is activated according to the dorsal jet nozzle usage pattern and the foot jet usage pattern.
(2) (3) From (3), the bath water in the set jet mode is spouted out (174), and the dorsal jet nozzle usage pattern switch (74) and foot jet nozzle usage pattern switch (75) are turned OFF. Then (175Y), the process returns to the preset pattern. Also, turn on the dorsal jet nozzle usage pattern switch (74) and the ventral jet nozzle usage pattern switch (76).
Then (176Y), each jet nozzle (2) is activated according to the dorsal jet nozzle usage pattern and the foot jet usage pattern.
(2) (4) Bath water in the set jet mode is spouted from (4) (177). Further, when the dorsal jet nozzle usage pattern switch (74) and the ventral jet nozzle usage pattern switch (76) are turned off (178Y), the pattern returns to the preset pattern. Also, turn on the foot side jet nozzle usage pattern switch (75) and the ventral side jet nozzle usage pattern switch (76).
Then (179Y), each jet nozzle +3)(
3) (4) From (4), bath water in the set jet mode is spouted out (180), and when the foot jet nozzle usage pattern switch (75) and ventral jet nozzle usage pattern switch (76) are turned OFF ( 181Y), return to preset pattern. As mentioned above, while enjoying your bath, you can eject your favorite jet stream with your favorite jet nozzle usage pattern.
It is constantly checked whether the discharge pressure and rotation speed of the circulation pump (P) and the water level of the bath water in the bathtub body (1) are maintained normally (182). If there is an abnormality (182N), the abnormality lamp will blink and the operation of the circulation pump (183) will be stopped.If there is no abnormality (182Y), the operation of the circulation pump (183) will be stopped.
The discharge pressure and rotation speed of P) are checked (185), and the discharge pressure and rotation speed are feedback-controlled according to the deviation from the set values (140). Further, if there is no deviation (185Y), the ejection nozzle usage pattern lamp is lit (186). By lighting the lamp, the user can visually confirm which pattern is selected. After that, when the operation switch (60) is turned off (18
7Y), the operation of the circulation pump (P) is stopped (188)
be done. Next, the bubble volume setting lamps (66a) (67a), the bath water spout cycle setting lamps (70a) (71a), or the bath water spout strength setting lamps (68a) (69a) are turned off (189), and then the spout nozzle is turned off. The usage pattern setting rung goes out (190), and the jet operation mode lamp goes out (191), and the operation turns off (190).
2) The operation lamp (60a) turns off (193)
. Also, the operation switch (60) was not turned off (187N
), and while the driving time setting timer of the circulation pump 1 (P) is not completed (194N), the controlled operation of the circulation pump (P) is continued (140). Additionally, when the drive time setting timer is up (194Y), the operation of the circulation pump (P) is stopped (194Y).
88), and the following steps (189) to [193] above.
Follow. The mild blowing operation has been described above, but when the acupressure blowing operation is selected (130), steps (137) to (194) are followed in the same way as when the mild blowing operation is selected (128). In the case of acupressure blow operation, step (146)
In this case, the preset amount is set in advance so that a form of jet flow with a small amount of hot water jetted and a high jetting pressure can be obtained. Next, the case where pulse blow operation is selected (132) will be explained based on FIGS. 16e and 16f. Similar to when the mild blow operation is selected (128), it is checked again whether the water level of the bath water in the bathtub body (1) is above a certain level (200). And if the water level is not above a certain level (20ON)
If the bathtub is equipped with an automatic water heater, the abnormality lamp will blink (201), and hot water operation will start (202).
, raise the water level above a certain level. Next, when a water level above a certain level is detected, the controlled operation of the circulation pump (P) begins (203), and
The discharge pressure of the circulation pump (P) is detected by the pressure sensor (48), and it is checked whether the discharge pressure is normal (
204). If the above discharge pressure is abnormal, the abnormal lamp will blink (
205), and further stops the operation of the circulation pump (P) (206). Also, if the discharge pressure is normal (204N), the drive time setting timer of the circulation pump (P) will automatically turn on (
207). Next, the pulse blow usage lamp (jet flow operation mode lamp) lights up (208). Next, the period of ejection of bubbles or bath water, or the ejection strength of bubbles or bath water is adjusted to increase or decrease, as necessary, based on the respective preset values. That is, if neither of the cycle increase/decrease switches (7o) (70) provided on the remote controller (30) is turned on, the rotational speed of the circulation pump (P) changes and the ejection amount adjustment valve body (22) of each ejection nozzle is activated. ) and the opening/closing speed of the bubble volume control valve (5d) are maintained at preset values (20
9Y), bubbles and bath water are ejected at the period of the same brisect value (210) Moreover, in the case of pulse blow operation, step (209
) and the subsequent step (217), preset values are set in advance so that a type of jet flow in which the individual jet nozzles open and close periodically and the bath water is spouted and stopped alternately can be explored. ing. In addition, the cycle increase switch (71) that increases the cycle is turned on.
When continuing NL (211Y), the cycle increases more than the glisset value (212). In addition, the cycle reduction switch (70) that decreases the cycle is turned on.
If NL continues (214Y), the cycle will decrease from the preset value (215) In addition, if none of the hot water jet strength side switches (68069) installed on the remote controller (30) are ON, the circulation pump (P) The rotation speed width, the opening/closing width of the jet volume regulating valve body (22) of each jet nozzle, and the bubble volume regulating valve (5d)
) is maintained at the preset value (217Y), and bubbles and bath water are spouted at the strength of the preset value (218Y).
). In addition, if you turn on the bath water spout strong side switch (68) that increases the spout strength (spout pressure/spout amount) and continue (219Y
), the spout strength increases from the preset value.Also, turn on the bath water spout east side switch (69) to decrease the spout strength.
If it continues for L (222Y), the ejection strength will decrease from the preset value (223). After that, follow the steps for mild blow operation (15
4) to (194), during which the desired usage pattern of the jet nozzle can be selected by turning on the changeover switch. The pulse blow operation has been explained above, but the above air pulse blow In the same way as when driving is selected (132), steps (200) to (224) and steps (154) to (
194). In the case of pine surge blow operation, step (2)
G9) In (217), the preset value is set in advance so as to periodically change the jetting amount and jetting pressure of the bath water so that a form of jetting that alternates between mild blowing and acupressure blowing can be achieved. There is. In addition, in the case of ζ wave operation, step (209) (2
In step 17), the preset value is set in advance so that the number of revolutions of the circulation pump is periodically changed to create a form of jet flow in which the intensity of the ejection pressure of the bath water is periodically changed. In addition, in the case of air pulse blow operation, step (20
9) In (217), the preset values are periodically changed in advance for the air intake time and the air intake stop time by the air intake part (5), and the air intake time and the air intake stop time are changed in advance to determine whether the bath water contains bubbles or the bath water without bubbles. It is set so that it can take the form of a jet stream in which the jets of water are ejected alternately. (e) Effects According to the present invention, the following effects are produced. That is, the control unit controls the amount and pressure of bath water jetted into the bathtub body from the automatic variable jetting amount jetting nozzle, the air intake amount of the air intake section, and the rotation speed of the circulation pump.
It is possible to select from a wide variety of bath water spout forms. For example, mild blowing has a large amount of bath water spouted from an automatic variable spout nozzle and low jetting pressure, and acupressure blow has a low spouted amount of bath water and high jetting pressure from an automatically variable spout nozzle. Pulse blowing involves periodically opening and closing the automatic variable jetting amount jet nozzle to alternately spout and stop bath water, and periodically changing the jetting amount and jetting pressure of the bath water from the automatic variable jetting jetting nozzle. Then, a pine surge blow that alternates between the above-mentioned mild blow and acupressure blow,
Wave blow, which periodically changes the rotation speed of the circulation pump to periodically change the strength of the ejection pressure of bath water, and the air intake time by the air intake section, are used to prevent air bubbles from being mixed in. Since it can be changed to at least two of the plural forms of bath water and air pulse blow that alternately jets out bath water without air bubbles, it can sufficiently accommodate the wide variety of bathing preferences of bathers. I can do it.
