(6) discharge pressure of water pump

In the following description, the discharge pressure of the rinse water that the water pump 11 of Fig. 3 is discharged is called water pressure.In the present embodiment, use the past double acting pump that rinse water is pressurizeed by the reciprocating action of piston in cylinder as water pump 11.Therefore, when water pump 11 action, water pressure is to form roughly sine-shaped mode with one amplitude of fluctuation cyclical swing.In double acting pump, the revolving force of the pump motor 11m of Fig. 5 is the power of piston at this.Therefore, can regulate water pressure by the rotary speed of control of pump motor 11m.

For example, when the rotary speed of pump motor 11m (Fig. 5) raise, the variation frequency of water pressure uprised, and variable cycle shortens.In addition, it is big that the amplitude of fluctuation of water pressure becomes, and the change center uprises.On the other hand, when the rotary speed of pump motor 11m reduces, the variation frequency step-down of water pressure, variable cycle is elongated.In addition, the amplitude of fluctuation of water pressure diminishes, change center step-down.

The user can adjust switch 322,323 (Fig. 2) by manipulation strength and cleaning strength is made as multistage.Multistage cleaning strength is corresponding to multistage water pressure.In addition, multistage water pressure is corresponding to a plurality of rotary speeies of pump motor 11m.

In the control part 90 of Fig. 3, store the relation of adjusting a plurality of rotary speeies of multistage cleaning strength that switch 322,323 can set and pump motor 11m by manipulation strength.

By this, control part 90 is adjusted the rotary speed that cleaning strength that switch 322,323 sets comes control of pump motor 11m according to user's working strength.By this, water pressure is adjusted the setting of switch 322,323 corresponding to the user to intensity and is changed.

Even if the rotary speed of pump motor 11m is certain, water pressure is also corresponding to towards the change of the supply pressure of the rinse water of water pump 11 and change.In addition, has certain relation between the flow of the water pressure of water pump 11 and the rinse water that in the pipe arrangement 3 of Fig. 3, flows.In the present embodiment, control part 90 is according to the rotary speed of the mensuration flow value FEEDBACK CONTROL pump motor 11m of the flow transmitter 8 of Fig. 3.

At this moment, control part 90 memory by using intensity is in advance adjusted the relation of the flow of 322,323 the multistage cleaning strengths that can set of switch and rinse water, according to the rotary speed of this corresponding relation control of pump motor 11m, so that the mensuration flow value of flow transmitter 8 becomes and the cleaning strength corresponding flow of setting.By this, water pressure is adjusted to the corresponding pressure of setting of intensity being adjusted switch 322,323 (Fig. 2) with the user.

Flow transmitter 8 is sent to control part 90 at the average of certain hour (for example 0.5sec) as measuring flow value with the change flow of rinse water.

(7) discharge pressure of air pump

In the following description, the discharge pressure of the air that the air pump 14 of Fig. 3 is discharged is called air pressure.

As mentioned above, use diaphragm pump as air pump 14.In this air pump 14, the revolving force of the pump motor 14b of Fig. 8 is the power of barrier film 14h.Therefore, can regulate air pressure by the rotary speed of control pump motor 14b.

For example, when the rotary speed of pump motor 14b raise, the variation frequency of air pressure uprised, and variable cycle shortens.In addition, it is big that the amplitude of fluctuation of air pressure becomes, and the change center uprises.On the other hand, when the rotary speed of pump motor 14b reduces, the variation frequency step-down of air pressure, variable cycle is elongated.In addition, the amplitude of fluctuation of air pressure diminishes, change center step-down.Supply has driving pulse to pump motor 14b.By making the dutycycle change of driving pulse, can adjust the rotary speed of pump motor 14b.

Along with the flow change of rinse water is many, air is difficult for sneaking in the rinse water, and in the straight line stream 551 of Fig. 3, rinse water is difficult for being disconnected by air.By this, be difficult for cleaning independently water column of shower nozzle 540 ejection rinse water from the human body of Fig. 3.Therefore, in the present embodiment, the dutycycle of the driving pulse of control pump motor 14b increases air pressure with the increase along with the flow of rinse water.

In the control part 90 of Fig. 3, store the mapping of relation of the dutycycle of expression flow of rinse water and driving pulse in advance.The relation of the air pressure that the flow that this mapping is based on rinse water and the water column that is used to form rinse water are required is made.

Control part 90 is according to the rotary speed of the mensuration flow value and the predefined mapping FEEDBACK CONTROL pump motor 14b of flow transmitter 8.At this moment, control part 90 obtains the value of the dutycycle corresponding with the mensuration flow value of flow transmitter 8 from mapping, and the dutycycle of the driving pulse of pump motor 14b is adjusted to the value of being obtained.By this, irrelevant with the flow of rinse water, can be reliably from ejecting device 500 ejection water columns.

The chart of water pressure that Figure 19 is kept when being the ejection of expression water column and first pressure dependence of air pressure.In Figure 19, the longitudinal axis is represented pressure, and transverse axis is represented the time.In addition, dotted line wp represents the water pressure of water pump 11, and solid line ap represents the air pressure of air pump 14.

As shown in figure 19, in this example, the water pressure of water pump 11 is in the change of the scope intercycle ground of minimum value 0 to maximum value Pb.On the other hand, the air pressure of air pump 14 is roughly maintained the low value Pa of minimum value 0 height ratio maximum value Pb than water pressure definitely.

At this moment, shown in the oblique line of Figure 19, air pressure is periodically than water pressure height.At this moment, air is not as the bubble that is cut off, but sneaks into rinse water as air bolus.Therefore, when flowing in the straight line stream 551 of air bolus at Fig. 3, air bolus occupies the roughly whole of flowing path section.By this, the rinse water in the straight line stream 551 is cut off by air bolus, alternately is formed with water column and air bolus in straight line stream 551.Water column that flows in straight line stream 551 and air bolus are from the alternately ejection intermittently of buttocks ejiction opening 555a of Figure 16.

Especially, form smoothly, can suppress to be formed at the water column in the straight line stream 551 and the sectionalization of air bolus by inside with straight line stream 551.

Rinse water after buttocks ejiction opening 555a ejection becomes roughly spherical water column because of surface tension.By this water column is concentrated ejection intermittently to the part, and the rinse water of uniform flux is compared to the situation that the part sprays continuously, can improve cleaning force significantly.In addition, owing to utilize a spot of rinse water can obtain sufficient cleaning force, therefore, the rinse water of sneaking into air also has water-saving result.

Use in use under the situation of the rinse water after the heating, when the use quantitative change of rinse water for a long time, the preparation meeting of the rinse water that heats sometimes becomes insufficient.In the present embodiment, sneak into the rinse water of air by use, can the effective and instantaneous rinse water that heats that provides.At this moment, when the rinse water of sneaking into air contacted from ejiction opening 555a ejection and with atmosphere, water column was pressurized towards emission direction because of the expansion of air.Therefore, sneak into the rinse water of air, can improve the sensation of human body stimulating by use.

In this example, air pressure is maintained at roughly certain.At this moment, the air that supplies to human body cleaning shower nozzle 540 can be sneaked in the rinse water that supplies to human body cleaning shower nozzle 540 regularly.By this, clean shower nozzle 540 from human body and alternately spray the cleaning water and air regularly.By using this rinse water, the user can obtain the high cleaning sense of sense of stability.

As mentioned above, in this example,, therefore,, also can easily form the water pressure time point lower than air pressure even if under the more situation of the flow of rinse water, need not improve air pressure because water pressure changes periodically.

As described in this example,,, preferably use diaphragm pump with a plurality of (for example more than three) oscillating structural member 14e as air pump 14 air pressure being maintained under roughly certain situation.At this moment, the increase along with the quantity of oscillating structural member 14e can obtain more stabilized uniform air pressure.As obtaining roughly the air pump 14 of air pressure uniformly, also can use turbulence pump to replace diaphragm pump.

(8-b) second pressure dependence

The chart of water pressure that Figure 20 is kept when being the ejection of expression water column and second pressure dependence of air pressure.In Figure 20, the longitudinal axis is represented pressure, and transverse axis is represented the time.In addition, dotted line wp represents the water pressure of water pump 11, and solid line ap represents the air pressure of air pump 14.

As shown in figure 20, in this example, the water pressure of water pump 11 is in the scope intercycle ground change of minimum value Pc to maximum value Pb.On the other hand, the air pressure of air pump 14 is in the change of the scope intercycle ground of minimum value 0 to maximum value Pe.In addition, the maximum value Pe of air pressure is higher and lower than the maximum value Pd of water pressure than the minimum value Pc of water pressure.

At this moment, shown in the oblique line of Figure 20, air pressure is periodically than water pressure height.At this moment, air as the smaller bubble period that is cut off sneak in the rinse water.In this example, because a large amount of bubbles is sneaked in cleaning, therefore, zoarium becomes air bolus in the straight line stream 551 of Fig. 3.So when air bolus flowed in straight line stream 551, air bolus occupied the roughly whole of flowing path section.By this, the rinse water in the straight line stream 551 is cut off by air bolus, alternately is formed with water column and air bolus in straight line stream 551.

The variation frequency of air pressure is higher more than the variation frequency of water pressure, and then this effect is remarkable more.At this moment, owing to when water pressure reduces, carry out sneaking into of air more frequently, therefore,, also the air of regime flow can be sneaked into rinse water even if generation is offset between the variation frequency of the variation frequency of air pressure and water pressure.

The mode that diminishes step by step by the sectional area with straight line stream 551 forms straight line stream 551, can more effectively utilize air bolus to cut off rinse water in straight line stream 551.By this, water column and air bolus arrive the buttocks ejiction opening 555a of Figure 16, from the alternately ejection intermittently of buttocks ejiction opening 555a of Figure 16.

In addition, under the situation of second pressure dependence, by than the structure simple in structure under the first pressure dependence situation, can will supply to air that human body cleans shower nozzle 540 and sneak into regularly and supply to human body and clean in the rinse water of shower nozzle 540.By this, clean shower nozzle 540 from human body and alternately spray the cleaning water and air regularly.Consequently, clean shower nozzle 540 from human body and spray independently water column regularly.By using this rinse water, the user can obtain the high cleaning sense of sense of stability.

(8-c) the 3rd pressure dependence

The chart of water pressure that Figure 21 is kept when being the ejection of expression water column and the 3rd pressure dependence of air pressure.In Figure 21, the longitudinal axis is represented pressure, and transverse axis is represented the time.In addition, dotted line wp represents the water pressure of water pump 11, and solid line ap represents the air pressure of air pump 14.

As shown in figure 21, in this example, the water pressure of water pump 11 is in the scope intercycle ground change of minimum value Pf to maximum value Pg.On the other hand, the air pressure of air pump 14 is in the change of the scope intercycle ground of minimum value 0 to maximum value Ph.In addition, the maximum value Ph of air pressure is higher and lower than the maximum value Pg of water pressure than the minimum value Pf of water pressure.

At this moment, shown in the oblique line of Figure 21, air pressure is erratically than water pressure height.Therefore, in the time of water pressure can occurring and reduce air sneak into the situation of rinse water and water pressure when reducing air do not sneak into the situation of rinse water.At this moment, the number of times of sneaking into that carries out air within a certain period of time can produce deviation.By this, sneak into the flow change of the air of rinse water, in the straight line stream 551 of Fig. 3, form water column and air bolus erratically.

The variation frequency of air pressure is lower more than the variation frequency of water pressure, and then this effect is remarkable more.At this moment, can produce erratically air repeatedly sneak into rinse water during and air do not sneak into fully rinse water during.

Rinse water after buttocks ejiction opening 555a ejection becomes roughly spherical water column because of surface tension.In straight line stream 551, form erratically under the situation of water column and air bolus, from the also change erratically of size of the water column of buttocks ejiction opening 555a ejection.By using this rinse water, the user can obtain the erratic stimulation of rinse water.

Human body can be accustomed to this stimulation when being subjected to identical stimulation for a long time, the sensation that stimulates is reduced.Therefore, water column and air bolus by forming erratically to the human body ejection can suppress the reduction of human body to sensation.By this, the user can obtain the high cleaning sense of excitement, and can quicken just meaning.

By set the relation of water pressure and air pressure as described in this example, even if under the situation of using small-sized air pump 14 (Fig. 3), also the air of enough stable quantities can be sneaked into rinse water, the cleaning sense of user's hobby is satisfied in acquisition.

(8-d) other example

(8-d-1) in the above-described embodiment, the air pressure settings that also can be provided for sneaking into rinse water in the remote-control apparatus 300 of Fig. 2 becomes multistage air to adjust switch.

At this moment, the user can become multistage with air pressure settings by operation air adjustment switch.

Other routine charts of the water pressure that Figure 22 is kept when being the ejection of expression water column and the pressure dependence of air pressure.Specifically, this graphical presentation when with air pressure ejection water column, the water pressure the when user changes the setting of air pressure and the change of air pressure.

In Figure 22, the longitudinal axis is represented pressure, and transverse axis is represented the time.In addition, dotted line wp represents the water pressure of water pump 11, and solid line ap represents the air pressure of air pump 14.

As shown in figure 22, in this example, the water pressure of water pump 11 is in the change of the scope intercycle ground of minimum value 0 to maximum value Pb.Relative therewith, the air pressure of air pump 14 at time point t0 to the low value Pa of minimum value 0 height ratio maximum value Pb that is roughly maintained definitely between the time point t1 than water pressure.In addition, change the user after the time point t1 of setting of air pressure, air pressure is roughly maintained the little value Pi of ratio Pa definitely.At this moment, at the time point shown in Figure 22 bend, air is sneaked into rinse water.

Value Pi for example is 0.8 with the ratio of value Pa.At this moment, time point t 1 later air is sneaked into the mixed volume that the mixed volume of rinse water sneaks into rinse water than air among time point t0～time point t1 and is lacked.By selecting this air pressure, although the flow-rate ratio of air is less, on the contrary, the user is can use traffic more and have a rinse water of soft cleaning sense.

On the other hand, the user also can be altered to air pressure settings a higher side.For example, in Figure 22, also the ratio of value Pi and value Pa can be made as 1.3.At this moment, to sneak into the mixed volume that the mixed volume of rinse water sneaks into rinse water than air among time point t0～time point t1 many for the later air of time point t1.By selecting this air pressure, the user can use by air acceleration, the higher rinse water of excitement.In addition, because the amount of employed rinse water itself is less at this moment, the drying of the part after using at short notice.

(8-d-2) in the above-described embodiment, clean washing apparatus 100 (Fig. 1) has following structure, in a human body cleaning shower nozzle 540 (Fig. 3), comprise special-purpose these three streams of stream 553 (Fig. 3) of straight line stream 551 (Fig. 3), rotation stream 552 (Fig. 3) and women, but be not limited thereto.For example, clean washing apparatus 100 also can have the shower nozzle that comprises straight line stream 551 and rotation stream 552, the shower nozzle that comprises the special-purpose stream 553 of women.

At this moment, when the user used the shower nozzle that comprises straight line stream 551 and rotation stream 552, the shower nozzle that comprises the special-purpose stream 553 of women that the women can be taken notice of especially was received in the clean washing apparatus 100.By this, can provide much cleaner clean washing apparatus 100.

(8-d-3) in the above-described embodiment, as the example of water pressure change, make roughly sinusoidal wave shape ground change of water pressure, but be not limited thereto.For example, the wavy or rectangle of water pressure triangle is hummock changed.In addition, also can make the change brokenly of water pressure aperiodicity ground.In addition, the amplitude of the change of water pressure can not be certain also.

(8-d-4) in the above-described embodiment, as water pump 11 (Fig. 3), use small-sized piston pump, but be not limited thereto.For example, also can utilize plunger displacement pump or diaphragm pump.In addition, also can utilize large-scale piston pump.At this moment, water pump 11 can be located at the outside of main part 200 (Fig. 1).

The variation frequency of water pressure is determined with the ratio of the displacement of water pump 11 by the flow of the rinse water that supplies to water pump 11.In the above-described embodiment, adopt the heat interchanger 9 (Fig. 3) of the transient heating mode that rinse water is heated at once.Therefore, the flow that supplies to the rinse water of water pump 11 is 300～500cc/min.On the other hand, for employed water pump 11 is installed in the limited space, use the small-sized water pump 11 of displacement as 0.15cc.At this moment, the variation frequency of water pressure is 33.3～55.6Hz.

Relative therewith, when using large-scale piston pump, because displacement increases, the variation frequency of water pressure also uprises.By this, as described in the 3rd pressure dependence, can more easily form the rinse water that water column and air bolus form erratically.

(8-d-5) in the above-described embodiment, in order to set water pressure and air pressure suitably, according to the flow of flow transmitter 8 (Fig. 3), control part 90 (Fig. 3) control of pump 11 (Fig. 3) and air pump 14 (Fig. 3).The controlled quentity controlled variable that is used to set water pressure and air pressure is different because of the shape of the T word pipe 503 (Fig. 5) that makes rinse water and air interflow.

In the example of Figure 23 (c), rinse water inflow pipe 503a vertically is provided with respect to air inflow pipe 503b that is set as linearity and effuser 503c.The internal diameter of rinse water inflow pipe 503a, air inflow pipe 503b and effuser 503c for example is 6.0mm, is provided with the jet 503d that for example has the 1.15mm internal diameter in air inflow pipe 503b.

In the example of Figure 23 (b), air inflow pipe 503b vertically is provided with respect to rinse water inflow pipe 503a that is set as linearity and effuser 503c.The internal diameter of rinse water inflow pipe 503a and effuser 503c for example is 6.0mm, as air inflow pipe 503b, uses the jet that for example has the 1.3mm internal diameter.

In the above-described embodiment, use the T word pipe 503 shown in Figure 23 (a), but be not limited thereto.Also can use the T word pipe shown in Figure 23 (b)～Figure 23 (d) according to controlled quentity controlled variable to water pump 11 and air pump 14.

(8-d-6) in the above-described embodiment, the flow of the rinse water that flow transmitter 8 (Fig. 3) is obtained is stored as reflection in advance with relation to the dutycycle of the driving pulse of the air pump 14 of Fig. 3, use the dutycycle of this reflection control driving pulse, to be controlled to the corresponding pressure of cleaning strength that sets with the user from the pressure that human body cleans the rinse water of shower nozzle 540 ejection, but be not limited thereto.For example, also can between the T of Fig. 5 word pipe 503 and buttocks ejiction opening 555a, pressure detector be set, according to the water pump 11 of the detected pressure control chart 3 of pressure detector, thereby will be controlled to the corresponding pressure of cleaning strength that sets with the user from the pressure that human body cleans shower nozzle 540 ejection.

(8-d-7) in the 3rd pressure dependence, control in the mode that the variation frequency of air pressure is littler than the variation frequency of water pressure, but be not limited thereto.For example, also can make at least one control that changes erratically in the variation frequency of the variation frequency of water pressure and air pressure.

At this moment, in the straight line stream 551 of Fig. 3, water column and air bolus are further formed erratically.Therefore, more irregular from the size of the water column of the buttocks rinse water ejiction opening 555a of Figure 16 ejection.By using this rinse water, the user can obtain more erratic stimulation, in addition, can further quicken just to anticipate.

(8-d-8) when the ability of water pump 11 can not reach the maximum cleaning strength that the user can set, also can be by improving the air pressure of air pump 14, will be controlled to the pressure corresponding from the pressure that human body cleans the rinse water of shower nozzle 540 ejections with maximum cleaning strength.
