[III] Description of Jet Form Hereinafter, jet forms (mild blow, acupressure blow, pulse blow, wave blow, cycle blow and program blow) obtained by the present embodiment will be described.
A description will be given with reference to FIGS. 16 to 26. [III-1] Mild blow Mild blow is performed for each jet nozzle (2) (3) (4)
It is a jet form in which the amount of bath water spouted from the bath is large and the jet pressure is low, wrapping the whole body of the bather mildly and softly, giving the bather the feeling of stimulating massage. That is, mild blow is performed for each jet nozzle (2).
(3) Each of the ejection amount adjusting valve bodies (22) of (4) is substantially fully opened, and the rotation speed of the circulation pump (P) is changed within a certain range (for example, within a range of 1700 to 3000 rpm). Then, the discharge pressure of the pump (P) is set to several levels (for example, five levels) within a low pressure range (for example, 0.2 to 0.5 kg / cm ² ) which is set to be constant, and each ejection nozzle (2) is set. (3) (3) (4) It is possible to jet a larger amount of bath water (for example, 40 to 80 l / min). FIG. 16 shows the ejection amount-ejection pressure characteristic curves (F1) (F2) that change with the change in the rotation speed of the circulation pump (P).
(F3) is illustrated, and (N1), (N2), (N3), and (N4) are rotation speed performance curves of the circulation pump (P). However, the magnitude relationship of the rotation speeds is N1>N2>N3> N4. The point (b) on the ejection amount-ejection pressure characteristic curve (F1) in FIG. 16a is when the rotation speed of the circulation pump (P) is near the maximum (N1) (for example, 3000 rpm). Shows the state of mild blow. (Y1) indicates a mild blow zone, and points (b1) and (b2) indicate a mild blow state set in the mild zone (Y1). FIG. 17 illustrates the ejection nozzle characteristic curves R1, R2, and R3 when the ejection amount adjusting valve body (22) is fully opened, half opened, and quarter opened. u1, u2, u3 ... are ejection pressure lines. However, the magnitude relationship of the ejection pressure is u1 <u2 <
u3 ... The point (b) in FIG. 16a can be indicated by a point (b ′) on the ejection nozzle characteristic curve (R1) shown in FIG. 17a. In FIG. 17A, (Y′1) indicates a mild blow zone in the ejection nozzle characteristics, and the point (b ′)
1) (b'2) is the mild blow zone (Y'1)
The state of the mild blow set in is shown. The above-mentioned mild blow is operated by turning on the mild blow switch (61) of the remote controller (30). In addition, the switching of each switch when changing the level of mild blow or changing the ejection nozzle use pattern is performed in a short time (for example, about 1 second). Fig. 18 shows the foot, back, and ventral ejection nozzles (2).
(3) opening and closing operation of each ejection amount adjusting valve element (23) in (4);
5 is a timing chart of the operation of a circulating pump (P). Each of the ejection amount adjusting valve bodies (22) of the foot side, back side, and ventral side ejection nozzles (2), (3), and (4) has a fixed time (t1) (for example, 0) after the mild blow switch operation (t0). After a lapse of (sec), a predetermined time (t2) (for example, 1 second) is at a high speed (preferably the maximum speed), and is set at a set valve opening position (d2) from the middle opening position (d1) (the valve opening position before the change of the jet flow). ) (For example, the valve is opened 6 mm backward from the fully closed position). Then, the circulation pump (P) starts rotating immediately before the time (t'1) at which the set valve opening operation of each ejection amount adjusting valve element (22) is completed (t'1) elapses before changing the jet flow form (V1) ( For example, 2800 r.pm) is gradually reduced to a certain time (t ′).
2) The rotation speed (V2) (for example, 2400 rpm) is set to be constant within (for example, 3 seconds). In this embodiment, the operation is started (the operation switch (6
When (0) or (100) is turned ON), the blow operation is started. At the start of the blow operation, the rotation speed of the circulating pump (P) is considered in consideration of safety when bathing children and the elderly. It has a child safety function that increases slowly. Then, the subsequent jet form is set as a mild blow, which is the above-mentioned gentle blow, and the strength level is initially set to “medium”. Moreover, in this embodiment, as shown in the timing chart of FIG. 19, at the start of operation, only the ejection amount adjusting valve element (22) of the back ejection nozzle (3) is once closed to the fully closed position. In addition, it is possible to prevent the cold remaining water in the pipe used previously from being ejected by the back-side ejection nozzle (3), thereby giving a bather discomfort or causing a danger to the bather (hereinafter, referred to as “danger”). This blow operation is referred to as “child safety blow”). That is, in FIG. 19, the ejection amount adjusting valve body (22) of the back side ejection nozzle (3) is kept constant for a certain time (t1) (for example, 0 second) after the mild blow switch operation (t0). The time (t2) (for example, 1 second) is a high speed (preferably the maximum speed), the valve is operated from the intermediate position (stop position) to the fully closed position to close the valve, and the valve closed state is maintained for a predetermined time (t3). (For example, 2 seconds), then a certain time (t4)
(For example, one second) is operated at a high speed (preferably the maximum speed) up to a set valve opening position (d2) (for example, a valve opening position retracted 6 mm from the fully closed position). The ejection amount adjusting valve elements (22) of the other foot / ventral ejection nozzles (2) and (4) are operated when the mild blow switch is operated (t
After a lapse of a fixed time (t1) (for example, 1 second) from 0), the fixed time (t2) (for example, 1 second) is at a high speed (preferably the maximum speed), and is at a middle open position (d1) (stop position). It is operated to a substantially fully open position (d2) (for example, a valve open position that is retracted 6 mm from the fully closed position). And the circulating pump (P) is a back side jet nozzle (3)
The valve is operated immediately after the time (t'1) for ending the valve closing operation of the valve body (22) for adjusting the ejection amount of the valve has elapsed, and the number of revolutions is gradually increased gradually by inverter control for a certain time (t'2). Constant rotation speed (V2) within (for example, 10 seconds)
(For example, 2800r.pm). Further, the mutual control timing of the opening / closing operation of the ejection amount adjusting valve body (22) of each ejection nozzle (2), (3), (4) and the change of the rotation speed of the circulation pump (P) are uncomfortable to the bather. This is done in consideration of not giving pressure and preventing the discharge pressure of the circulation pump (P) from suddenly increasing. This will be described later in [IV-7]. . [III-2] Shiatsu blow Shiatsu blow is a jet form in which the amount of bath water spouted from each spout nozzle (2) (3) (4) is small and the spout pressure is high. By applying a vigorous jet, a bather is given a stimulating massage feeling with acupressure. That is, the acupressure blow is performed for each of the ejection nozzles (2) and (3).
(4) Each of the ejection amount adjusting valve bodies (22) is slightly opened to adjust the rotation speed of the circulation pump (P) within a certain range (for example, 2000 to 2000).
(Within the range of 3000 rpm) to keep the discharge pressure of the pump (P) constant within a high pressure range (for example, 0.5 to
1.0 kg / cm ² ), which can be set at several levels (for example, five levels). Further, the point (e) on the ejection amount-ejection pressure characteristic curve (F3) in FIG. 16a indicates that the ejection amount of the bathwater is the minimum (for example, 30 l /
min) indicates the state of the acupressure blow. In FIG. 16a, (Y2) indicates the acupressure blow zone in the ejection amount-ejection pressure characteristic, and points (e1) and (e2)
Indicates a shiatsu blow state set in the shiatsu blow zone (Y2). The point (e) in FIG. 16a can be displayed as a point (e ′) on the ejection nozzle characteristic curve (R3) shown in FIG. 17a. In FIG. 17A, (Y′2) indicates the acupressure blow zone in the ejection nozzle characteristic, and the point (e′1)
(E'2) shows the acupressure blow state set in the acupressure blow zone (Y'2). The above-mentioned acupressure blow is activated by turning on the acupressure blow switch (62) of the remote controller (30). Fig. 20 shows the foot, back, and ventral ejection nozzles (2).
(3) opening / closing operation of each ejection amount adjusting valve element (22) in (4);
5 is a timing chart of the operation of a circulating pump (P). That is, in FIG. 20, each ejection amount adjusting valve element (22)
Is a fixed time (t) from the time of operation of the acupressure blow switch (t0).
1) After a lapse of (for example, 0 second), a certain time (t2) (for example, 1 second) is at a high speed (preferably the maximum speed), and the valve opening position (d1) (for example, a completely closed position) before the change of the jet flow form 6m
The valve is operated to open from a set valve opening position (d2) (for example, a valve opening position retracted 1.5 mm from a fully closed position) from a valve opening position retracted by m. The circulation pump (P) starts rotating immediately before the time (t′1) at which the set valve opening operation of each ejection amount adjusting valve element (22) ends, before the change of the jet flow form (V1) ( For example, 2400 r.pm) is gradually increased to a certain time (t ′).
2) Constant rotation speed (V2) within (for example, 3 seconds) (for example,
2800r.pm). [III-3] Pulse blow Pulse blow is performed for each ejection nozzle (2) (3)
This is a jet form in which (4) is periodically opened and closed to alternately eject and stop the bath water. By pulsating or not emitting the jet, a sharp stimulus can be given to a bather. Things. That is, in the pulse blowing, in the acupressure blowing, the ejection amount adjusting valve body (22) of each of the ejection nozzles (2), (3), and (4) is shortly (for example, 1 second) every predetermined time.
The valve is alternately moved at a high speed (preferably the maximum speed) between the set valve opening position and the completely closed position. This allows
A state in which the bath water is spouted and a state in which the bath water is not spouted can be alternately generated. When the bath water is ejected, there are cases where bubbles are contained and cases where bubbles are not contained. And the change of the strength level of the pulse blow is
By changing the number of revolutions of the circulation pump (P), the amount of bathwater spouting can be set in several steps (for example, five steps) within a certain range (for example, within 30 to 50 l / min). The above-described pulse blow is operated by turning on a pulse blow switch (63) of the remote controller (30). FIG. 21 shows the foot, back, and ventral ejection nozzles (2).
(3) opening / closing operation of each ejection amount adjusting valve element (22) in (4);
5 is a timing chart of the operation of a circulating pump (P). That is, in FIG. 21, each ejection amount adjusting valve element (2
In 2), after a certain period of time (t1) (for example, 0 seconds) has elapsed from the time of operation of the pulse blow switch (t0), the valve was opened (d1) (for example, retracted 6 mm from the fully closed position) before the change of the jet flow form. A fixed time (t2) from the valve opening position) to the set valve opening position (d2) (for example, the valve opening position retracted 2 mm from the fully closed position)
(For example, 1 second) is operated at a high speed (preferably the maximum speed), and the valve opening state is maintained for a certain time (t3) (for example, 1 second)
After being maintained, the valve is closed at a high speed (preferably the maximum speed) to the fully closed position for a predetermined time (t4) (for example, 1 second), and the fully closed state is maintained for a predetermined time (t5) (for example, 1 second). ), The valve is opened at a high speed (preferably the maximum speed) to the set valve opening position (d2) for a predetermined time (t6) (for example, 1 second), and the valve is opened for a certain time ( t7) The opening / closing valve operation of maintaining the valve (for example, 1 second) and then closing the valve is periodically repeated. Then, the circulation pump (P) is operated for a fixed time (t'1) (for example, 1 second) from the time of operation of the pulse blow switch (t0).
After elapse, the number of revolutions (V1) before changing the jet form (for example,
2400r.pm) and gradually increase it for a certain time (t'2)
Within (for example, 3 seconds), the rotation speed is set to a constant rotation (V2) (for example, 2800 rpm). Also, a fixed time (t3) for maintaining the above set valve open state
Can be set to different pulse blow patterns, but in the present embodiment, the pulse blow A in which the fixed time (t3) is set to 1 second, 2 seconds, and 3 seconds is set.
Three types of patterns B and C are set so that the stimulation time given to the bather by the jet can be selected as desired. [III-4] Wave blow Wave blow is a jet form in which the rotation speed of the circulation pump (P) is periodically changed to periodically change the ejection amount and ejection pressure of the bath water. By changing the pressure in a slow cycle, it creates a varied flow and gives the bather a jet of the image of the returning wave. That is, the wave blow is performed by each ejection nozzle (2).
(3) With each valve (22) for adjusting the amount of ejection in (4) fully open or in the middle open state, the operation of the circulation pump (P) is turned ON / OFF.
Alternatively, the rotation speed of the circulation pump (P) is periodically changed within a certain range (for example, within a range of 1600 to 3000 rpm). The level of the wave blow is changed by setting the range of the number of rotations of the circulation pump (P) to be changed periodically in several steps (for example, five steps) within the above-mentioned constant number of rotations. be able to. In addition, (d1), (d2), and (d3) shown in FIG. 16b are the ejection amount-ejection pressure characteristic curves of the wave blow, respectively, along the curves (d1), (d2), and (d3). The ejection amount and ejection pressure change. Also, (d'1) (d'2) (d ') shown in FIG.
3) is a characteristic curve of the jet nozzle of wave blowing, and the amount of bubbles can be greatly changed by wave blowing. The above-described wave blow is activated by turning on the wave blow switch (65) of the remote controller (30). The usage pattern of the jet nozzles for jetting the bath water of the wave blow is the same as in the case of the mild blow described above. Fig. 22 shows the foot, back, and ventral ejection nozzles (2).
(3) opening / closing operation of each ejection amount adjusting valve element (22) in (4);
6 is an operation timing chart of a circulating pump (P). That is, in FIG. 22, each ejection amount adjusting valve element (2
In 2), after a certain time (t1) (for example, 1 second) has elapsed after the operation of the wave blow switch (t0), the valve is opened (d1) (for example, 6 mm behind the fully closed position) before the jet flow is changed. A fixed time (t2) from the valve position) to the set valve opening position (d2) (for example, the valve opening position retracted 4 mm from the fully closed position)
(Eg, one second) is operating at a high speed (preferably the maximum speed). Then, the circulation pump (P) starts rotating immediately before the time (t3) at which the set valve opening operation of each ejection amount adjusting valve element (22) is completed (t3), and the rotation speed (V1) (for example, twenty four
00r.pm) is gradually increased to a constant high rotation speed (V2) (for example, 3000 r.m.) within a certain time (t4) (for example, 4 seconds).
pm) and then gradually decrease the number of revolutions for a certain time (t
5) Low rotation speed (V3) (for example, 180 seconds) within (for example, 4 seconds)
0r.pm), and the rotation speed is gradually changed so that the rotation speed is gradually increased to reach the above-described high rotation speed (V2) within a certain time (t6) (for example, 4 seconds). . Further, a different wave blow pattern can be set by changing the method of periodically changing the rotation speed of the circulation pump (P). In the present embodiment, the above-described wave blow pattern is referred to as a wave blow A, Wave blow pattern described below
As C, three types of patterns are set. That is, as shown in the timing chart of FIG. 23, the wave blow B starts immediately after the time (t3) at which the set valve opening operation of each ejection amount adjusting valve element (22) ends (t3).
Rotational speed (V1) before jet flow change (for example, 2400r.pm)
Is gradually increased to a constant high rotation speed (V2) (for example, 3000 rpm) within a fixed time (t4) (for example, 4 seconds),
The high rotation speed (V2) is maintained for a predetermined time (t5) (for example, 2 seconds), and thereafter, the rotation speed is gradually reduced for a predetermined time (t
6) Low rotation speed (V3) (eg, 180 seconds) within (eg, 4 seconds)
0r.pm), the same low rotation speed (V3) is continued for a certain time (t7) (for example, 2 seconds), and then the rotation speed is gradually increased, and the rotation speed is gradually increased within a certain time (t8) (for example, 4 seconds). The rotation speed is periodically changed, for example, to achieve a high rotation speed (V2). Further, as shown in the timing chart of FIG. 24, the wave blow C starts immediately after the time (t3) at which the set valve opening operation of each ejection amount adjusting valve element (22) ends, and immediately before the change of the jet flow form. The rotation speed (V1) (for example, 2400 rpm) is gradually increased so as to draw a downward convex curve for a fixed time (t4)
(For example, 3 seconds) within a certain high rotation speed (V2) (for example,
3000r.pm), and then a low rotation speed (V3) (for example, 1800r.pm) within a certain time (t5) (for example, 3 seconds) so that the rotation speed draws a downward convex curve. For a certain time (t6) by gradually increasing
The rotation speed is periodically changed such that the above-mentioned high rotation speed (V2) is obtained within (for example, 3 seconds). In the present embodiment, in particular, since the rotation speed of the circulation pump (P) is controlled by the inverter (E), the rotation speed of the circulation pump (P) is periodically and smoothly changed without fail. Wave blows A, B, and C having pulsating strength can be generated in a weak jet. Among them, in the wave blow C, the rotation speed of the circulation pump (P) changes along a substantially catenary curve, the rotation speed increase rate and the rotation speed reduction rate near a high rotation speed are large, and the rotation speed near the low rotation speed is large. Due to the low rate of increase and decrease of the number of revolutions, strong changes in the jet are relatively short, and weak changes in the jet are relatively long. Jet form with [III-5] Cycle Blow Cycle blow is a technique that allows the location of the bathwater to be spouted by automatically and periodically changing the position at which the bathwater is spouted. That is, the cycle blow is performed, for example, in the order of the back ejection nozzles (3) and (3) → the abdominal ejection nozzles (4) and (4) → the foot ejection nozzles (2) and (2) for a certain period of time. The bath (22) is opened and the bath water is spouted. At this time, the bath water form spouted from each of the jet nozzles (2), (3) and (4) depends on the valve body (22) for adjusting the amount of the spout. By adjusting the opening / closing amount and the rotation speed of the circulation pump (P), it is possible to adopt a mild blow, acupressure blow, a wave blow, and a jet form in which the mild blow and the acupressure blow are periodically changed. In the present embodiment, three types of cycle blows A, B, and C are set.
B and C will be described with reference to the timing charts shown in FIGS. 25 and 26. The cycle blow A takes the form of acupressure blow, and as shown in the timing chart of FIG. 25, after a predetermined time (t1) (for example, 0 second) has elapsed since the cycle blow switch operation (t0), the back side The valve opening position (d1) before changing the jet flow mode with only the jet volume adjusting valve element (22) of the jet nozzle (3)
(Eg, a valve opening position retracted 6 mm from the fully closed position) from the set valve opening position (d2) (eg, 1.5 mm from the fully closed position
(T2) (for example, 1
Second) is operated at a high speed (preferably the maximum speed), and the other foot-side jet nozzle (2) and the ventral jet nozzle (4)
Each of the ejection amount adjusting valve bodies (22) is closed at a high speed (preferably the maximum speed) for a predetermined time (t2) (for example, 1 second) until the completely closed position. In this state, the acupressure blow-type bath water is jetted only from the back jet nozzles (3) and (3). Then, the valve body (22) for adjusting the ejection amount of the back ejection nozzle (3) is held at the valve opening position (d2) for a fixed time (t3) (for example, 2 seconds), and then for a fixed time (t4) ( For example, 1
Second) at a high speed (preferably the maximum speed) to close the valve to the fully closed position. Subsequently, the valve (22) for adjusting the ejection amount of the ventral ejection nozzle (4) in the valve closed state is kept for a certain time (t5) (for example, 0).
After a lapse of a second), a certain time (t6) (for example, 1 second) is operated at a high speed (preferably the maximum speed) to the set valve opening position (d2), and the same setting is performed for a certain time (t7) (for example, 2 seconds). After holding the valve at the valve open position (d2), a certain time (t8) (for example, 1
Second) at a high speed (preferably the maximum speed) to close the valve to the fully closed position. In this state, the acupressure blowing bath water is ejected only from the ventral ejection nozzles (4) and (4). Subsequently, the ejection amount adjusting valve body (22) of the foot-side ejection nozzle (2) in the valve closed state is set for a predetermined time (t9) (for example, 0
After a lapse of a second), a predetermined time (t10) (for example, 1 second) is operated at a high speed (preferably the maximum speed) to the set valve opening position (d2), and the same setting is performed for a predetermined time (t11) (for example, 2 seconds). After holding the valve at the valve opening position (d2), the valve is closed at a high speed (preferably the maximum speed) to a completely closed position for a certain time (t12) (for example, one second). In such a state, the acupressure blow bath is jetted only from the foot jet nozzles (2) and (2). Subsequently, the ejection amount adjusting valve element (22) of the back-side ejection nozzle (3) in the valve closed state is set for a predetermined time (t13) (for example, 0
After a lapse of a second), a predetermined time (t14) (for example, 1 second) is operated at a high speed (preferably the maximum speed) to the set valve opening position (d2) at the high speed (preferably the maximum speed), and the same setting is performed for a predetermined time (t15) (for example, 2 seconds) After holding the valve at the valve opening position (d2), the valve is closed at a high speed (preferably the maximum speed) to a completely closed position for a predetermined time (t16) (for example, 1 second). Further, the circulation pump (P) has been operated for a certain period of time (t'1) (for example, 0 seconds) from the time of operation of the cycle blow switch (t0).
Rotation speed (V1) before jet shape change after elapse (for example, 2800
rpm) to gradually decrease the rotation speed (V2) (for example, 2500 v.p.) within a certain time (t'2) (for example, 1 second).
m), and the same rotation speed (V2) is maintained during the blow operation. The cycle blow B employs the acupressure blow mode. In the timing chart of the cycle blow A, the setting of the ejection amount adjusting valve body (22) of each ejection nozzle (2), (3), (4) is performed. The fixed time (t3) (t7) (t11) for holding the valve opening position (d2) is different (for example,
4 seconds). As described above, in the cycle blows A and B, the ejection amount adjusting valve elements (22) of the ejection nozzles (2), (3), and (4) are sequentially set in the order of dorsal side → ventral side → foot side → back side. Since the opening and closing operation is performed periodically and the rotation speed of the circulating pump (P) is kept constant, it is possible to give a shiatsu effect to the bather's body while changing the position of the spout of the acupressure blow. it can. Further, the cycle blow C employs a wave blow mode, and as shown in the timing chart of FIG. 26, the set valve opening position (d2) is set to be higher than the set valve opening position (d2) of the cycle operation AB. Increase the value (for example, 4 mm) and maintain the same valve opening position (d2) for a certain period of time (t3) (t7) (t1
1) is different from cycle blows AB (for example, 8 seconds). Further, the rotation speed of the circulation pump (P) is changed periodically. That is, the circulating pump (P) is turned on for a fixed time (t'1) (for example, 0
Seconds), the number of revolutions (V1) before changing the jet configuration (for example,
2400 rpm), and gradually reduced to a certain low rotational speed (v3) (eg, 1600) within a certain time (t′2) (eg, 1 second).
rpm), and then gradually increase the number of revolutions to increase the number of revolutions (V) within a certain time (t'3) (for example, 4 seconds).
2), and thereafter, the rotation speed is gradually reduced so that a certain low rotation speed (V3) is obtained within a certain time (t'4) (for example, 4 seconds).
And Then, after maintaining the constant low rotation speed (V3) for a fixed time (t'4) (for example, 1 second), the above-described change in the rotation speed (V3 → V2 → V3) is repeated. Such a change in the rotation speed (V3 → V2 → V3) is performed only while the bath water is being jetted from any of the jet nozzles (2), (3), (4), and each of the jet nozzles (2), (3) During the opening / closing operation of the injection amount adjusting valve element (22) of (4), the timing is adjusted so as to maintain a constant low speed (V3) to prevent a sudden change in the jet strength. , So as not to make the bather uncomfortable. Accordingly, the bath nozzle in the form of a wave blow is sprayed from each of the spray nozzles (2), (3), (4) which are repeatedly operated and stopped at a constant cycle. You can enjoy the jet that gives a distinctive wave image. Further, in the present embodiment, the change of the bathwater jetting positions of the cycle blows A, B, and C is changed from the back side to the abdomen side to the foot side to the back side. However, the order is not limited to this order. (For example, dorsal side → foot side → ventral side → dorsal side) can also be adopted. In addition, the position at which the bathwater is spouted can be changed irregularly. [III-6] Program blow Program blow is a diversification of jet changes by arbitrarily combining or changing the jet form, jet strength, and jet spot location according to a preset program, or changing over time. It is possible to enjoy a surprising combination of jet forms that is not a standard wiping method. Further, in this embodiment, in consideration of the age, sex, etc. of the bather, a plurality of programs having different contents are prepared, and the program blow which is a standard blow operation having the most common menu is provided. A, a program blow B which is a hard blow operation having the most intense menu, and a program blow C which is a light blow operation which is lightest and gentle. The program blows A, B and C are as shown in the program blow specifications in Table 1. In Table 1, ranks 1, 2, and 3 respectively divide the plurality of jet forms described above into three groups, and classify the probability of appearance of the jet forms in the same group into three stages. The appearance probability of the jet form belonging to rank 1 is 50%, and the appearance probability of the jet form belonging to rank 2 is 30
%, And the appearance probability of the jet form belonging to rank 3 is set to 20%. In addition, the strength level of the jet is set to five levels,
Medium-low is displayed as 2, medium is displayed as 3, medium-high is displayed as 4, and high is displayed as 5. In the program blow A, the strength level of the jet is set to 2 to 4 in order to perform the standard blow operation, and in the program blow B, the strength level of the jet is set to 3 in order to perform the hard blow operation. In the program blow C, the strength level of the jet is set to 1 to 3 in order to perform a light blow operation. Also, the location of the bath (spout location) is
Ventral jet nozzles (2), (3), and (4): simultaneous injection at three locations, simultaneous injection at any two locations;
There are cases where there are multiple locations, and the case of simultaneous ejection at three locations is indicated as (foot / back / belly), and the case of simultaneous ejection at two locations (foot / back)
(Back / belly) (foot / belly), and one place (foot)
(Back) (belly) is displayed. In addition, each jet form, the strength level of the jet, and the jetting position of the bath water are switched after a certain period of time (for example, 30 seconds), so that the enjoyment of the change is continuously given to the bather,
Try not to bore the bathers. In addition, the jet form prevents the same form from appearing continuously, thereby ensuring the enjoyment of the change given to the bather. Further, each of the program blows A, B, and C can set the blow time constant. In this embodiment, the program blow A is set to 4 minutes, the program blow B is set to 5 minutes, and the program blow C is set to 3 minutes. ing. In addition, several types of menus are set for each of the program blows A, B, and C, and when any one of the program blows is selected, the menu is randomly selected from the selected program blows. You can also. Thus, the program blow A, B, C
Since the jet form, jet strength, and jet location are changed irregularly in consideration of gender, bathers can fully enjoy the unexpectedness of the changes and the order of the changes, and become bored during bathing. Never do.

Akira The strength of the operating procedure based on the flowchart in [IV-1]
Weak level is "strong""strongmedium""medium" for each jet form
Set the level to five levels of "Medium low" and "Low"
Considering the contents of the flow form, the strength is varied,
Even if the level display is the same, if the jet form is different, the jet strength
Are different. The state transition at the dynamic level is shown in Table 4.
That's right. In Table 4, the operation was stopped vertically and the five levels
Weak level (strong, strong medium, medium, medium weak, weak) and program block
-A, B, and C are listed, and each state number is
It is listed next to the corresponding right, and the operation switch (driving

You. And the strength level is the hot water spouting high side switch (68)
Or the direction in which one step strength increases when (107) is pressed and released
Transition to the opposite, and on the other hand, the bath water jet weak side switch (69) or
Pressing and releasing (108) moves in a direction to decrease one-step strength
I am trying to move it. For example, if the operation switch (100) is turned on, the operation will stop.
Medium (state number “0”)
No. “3”), and the bath is injected from the same level “Medium”
Press and release the power switch (68) or (107) to increase or decrease
The level transitions to “strong middle” (state number “4”) and the switch
Switch (68) or (107) again and release it.
Bell transitions to "strong" (state number "5")
You. Also, from the level "Medium", switch on the weak side of bath water spout
Press (69) or (108) and release to change
"Weak" (state number "2") and switch (69) or
Press and release (108) again to decrease the dynamic level
(State number “1”). In program blows A, B, and C,
Because the bell is pre-programmed,
Operate the high / low switch (68) (69) or (107) (108).
Even if you make it, you can not change the strength level. In Table 4, “ON” indicates the operating strength.
This indicates that the level display lamp is turned on. In addition, “ON / OFF” indicates that the level cannot be changed.
When the program blow A, B, or C is operating,
Indicates that the bell display lamp blinks. Also,
“-” Indicates no change, “•” indicates OFF state.
You. Thus, at the start of the blow operation,
Because the setting is set to “medium,”
The extra strength does not cause discomfort to the bather,
Also, when the bather is a child or the elderly, the bather gulp
The trouble of falling down due to the foot being taken by hot water
Can be prevented. Also, if the dynamic level is increased or decreased,
In order to make the transition one step at a time,
Can be prevented from suddenly changing
Water hammer due to sudden rise in water pressure in pipes, etc.
Can prevent damage to the piping. [VI-6] Explanation of the priority of the main operation specifications in the operation procedure based on the flowchart in [IV-1]
The priority order of the required operation specifications is as shown in Table 5.
You. In this way, by giving priority to stopping at high water temperature,
Ensure safety and other driving
Preservation of bathers and each component by setting priorities
And perform optimal control to achieve efficient operation
Like that. [IV-7] Opening / closing operation of the ejection volume control valve and circulation pump rotation
Control timing for changing the number of turns Opening of the foot, back, and ventral nozzles (2), (3), and (4)
Control timing of closing operation and change of rotation speed of circulation pump (P)
Tables 6 and 7 below are used. As shown in Table 6, when changing the jet configuration,
If it is necessary to increase the rotation speed of the pump (P),
Each ejection nozzle rather than changing the rotation speed of the circulation pump (P)
(2) Prioritize the opening and closing operations of (3) and (4), and circulate
When it is necessary to lower the rotation speed of the pump (P),
Circulation rather than opening and closing operation of each ejection nozzle (2) (3) (4)
Priority is given to a change in the number of revolutions of the pump (P). Also, as shown in Table 7, when changing the number of jets,
When reducing the number of jets, each jet nozzle (2) (3)
The rotation speed of the circulation pump (P) is lower than the valve closing operation of (4).
To increase the number of jets
Indicates that each ejection noise is greater than the rotation speed of the circulation pump (P).
(2), (3) and (4). Thus, when changing the jet form or changing the number of jets,
Opening and closing operations of the ejection nozzles (2), (3) and (4),
The control timing differs from the change in the rotation speed of the ring pump (P).
The bather can prevent bathers from changing
It is possible to prevent pleasure,
To prevent a sudden change in the discharge pressure of the pump (P)
It is possible to prevent piping damage due to tar hammer etc.
Wear.
