With reference to Fig. 4, the surface structure of the water smoke maker 100 that embodiments of the present invention are related to describes.

Water smoke maker that embodiments of the present invention relate to 100 following parts constitute: by 2 piezoelectrics 131 and piezoelectrics 132 being engaged the oscillator 20 that constitutes, be bonded on the rear portion ultrasonic horn 133 of end face thereafter and be bonded on the anterior ultrasonic horn 134 of the front end face of oscillator 20.

And the leading section feedwater by to anterior ultrasonic horn 134 makes leading section carry out ultrasonic vibration, thereby generates water smoke.Then, the water smoke of generation is sprayed in water smoke maker 100 tank 214 outward.

In addition, though do not illustrate, in this example,, become the structure that is set at water smoke maker 100 as an example at each component parts of the vibration unit 70 beyond the oscillator 20.

With reference to Fig. 5, the frequency characteristic of the oscillator 20 (piezoelectric ceramic vibrator) that present embodiment is related to describes.

Among Fig. 5, the longitudinal axis represents that impedance, transverse axis represent the frequency of oscillator 20.

For the frequency characteristic of oscillator 20 (piezoelectric ceramic vibrator), in the frequency of giving be to piezoelectric ceramic vibrator under the situation of resonant frequency f (1) (under the situation of present embodiment, the value of resonant frequency is made as 39.50kHz), the impedance minimum of piezoelectric ceramic vibrator.

And be under the situation of anti-resonance frequency f (2) (under the situation in present embodiment, the value of anti-resonance frequency being made as 40.10kHz) in the frequency of giving to oscillator 20 (piezoelectric ceramic vibrator), the impedance maximum of piezoelectric ceramic vibrator.

Under the situation of using oscillator 20 (piezoelectric ceramic vibrator), as described above, even the piezoelectric ceramic vibrator of same specification, frequency characteristic (resonant frequency f (1), anti-resonance frequency f (2), impedance etc.) also there are differences between the individuality of each oscillator, and, the frequency characteristic time to time change of piezoelectric ceramic vibrator.

Therefore, need implement best vibration control to each oscillator.

With reference to Fig. 6, the control of embodiments of the present invention being used to of relating to being carried out the oscillator of water smoke control describes.

At first, to ultrasonic horn feedwater (step S1).Particularly, CPU60 control water smoke is opened water smoke with water-supply valve 44, from the leading section feedwater of water smoke water hose 210 to anterior ultrasonic horn 134 with water-supply valve 44.

Then, judge whether the feedwater to loudspeaker finishes (step S2).Under the situation that the feedwater that is judged as to loudspeaker is through with, enter into step S3 in step S2.Particularly, can judge according to whether having passed through from opening water smoke usefulness water-supply valve 44 to via the stipulated time of water smoke water hose 210 to the leading section feedwater of anterior ultrasonic horn 134.Following processing mainly is the processing of being carried out by vibration unit control part 62.

In step S3, carry out initial setting and handle.

With reference to Fig. 7, at first, handle as initial setting, be the higher limit (step S21) of high frequency side with frequency setting.

Particularly, with frequency setting (predetermined frequency) near anti-resonance frequency.

Then, as the adjustment state, set reduction pattern (step S22) for as the pattern that frequency is reduced.

Then, (step S23) handled in the output of beginning frequency.Particularly, control vibration unit 70 vibrates its vibration frequency with the higher limit of the high frequency side that sets.

Then, finish initial setting and handle (termination).

Referring again to Fig. 6, then carry out and adjust preceding confirm to handle (step S4).

Fig. 8 is a flow chart of confirming processing before explanation is adjusted.

With reference to Fig. 8, at first, detect loudspeaker electric currents (step S30).Particularly, acceptance is by the input of testing circuit 22 detected loudspeaker electric currents.

Then, judged whether to pass through the time (step S31) of 32msec.

Through before the time of 32msec, carry out the detection of the loudspeaker electric current among the step S30 repeatedly.Therefore, through before the time of 32msec, import repeatedly loudspeaker current value to vibration unit control part 62.Wherein, whether pass through the time of 32msec, for example can use timer 64 to carry out instrumentation.For the processing of the process of the judgement time in the following explanation too.

Then, calculate the mean value (step S32) of loudspeaker electric current I h.

The detection of loudspeaker electric current needs 2msec each time.Therefore, in the time of 32msec, can carry out the detection of No. 16 loudspeaker electric currents.

Then, calculate the mean value of No. 16 loudspeaker electric currents, as loudspeaker electric current I h.

Then, the loudspeaker electric current I h# that the loudspeaker electric current I h that calculates specifically and last computation are gone out compares, and whether the absolute value of judging its residual quantity is below the threshold value of regulation.

Particularly, judge whether to satisfy-condition (step S34) of 50mA＜Ih-Ih#≤50mA.

That is, be judged as difference between the loudspeaker electric current that the loudspeaker electric current that calculates specifically and last computation go out little, promptly almost do not have under the situation of change, confirm to handle (step S35) before finishing to adjust, enter into next step.In addition, under the situation of the loudspeaker electric current I h# that does not have last computation to go out, set predefined initial value.

On the other hand, when in step S34, do not satisfy-condition of 50mA＜Ih-Ih#≤50mA, promptly be judged as between the loudspeaker electric current that the loudspeaker electric current that calculates specifically and last computation go out difference greatly (in other words, change is big) situation under, loudspeaker electric current I h is set at the loudspeaker electric current I h# (step S36) that last computation goes out.

Then, judge the time (step S37) of whether having passed through 1sec from the beginning of adjusting preceding affirmation processing.

Under the situation of the time of not passing through 1sec, turn back to step S30, carry out above-mentioned processing repeatedly.

On the other hand, though when in step S37, being judged as the time of having passed through 1sec, under the big situation of the change of loudspeaker electric current because loudspeaker electric current instability, so be judged as unusual, error process (step S38).Then, make processing enter into step S9 described later.

Referring again to Fig. 6, after before the adjustment that is through with, confirming to handle, carry out adjustment modes and begin to handle (step S5).

In this example, as the example that adjustment modes begins to handle, carry out the processing of any one adjustment modes of reduction pattern, rising pattern and the inching pattern of adjusting frequency according to detected loudspeaker current value.

The reduction pattern is the adjustment than last time, the pattern when the direction that reduces frequency is adjusted frequency.

The rising pattern is the adjustment than last time, the pattern when the direction that improves frequency is adjusted frequency.

The inching pattern is to compare with the adjustment of last time, there is no need to adjust frequency, and perhaps frequency has been carried out the pattern of inching.

In this example, as the target zone of frequency, frequency is adjusted into detects greater than 340mA, smaller or equal to the loudspeaker electric current of 360mA.

(reduction pattern)

With reference to Fig. 9, in the processing that reduces pattern, the loudspeaker electric current I h that CPU60 at first will calculate specifically, deduct 50mA with the loudspeaker electric current I a# that goes out from last computation and the value that obtains compares, judged the value whether the loudspeaker electric current I h that calculates has specifically obtained more than or equal to the loudspeaker electric current I a# that goes out from last computation has deducted 50mA.Wherein, the initial value of loudspeaker electric current I a#, as an example, being set to the impedance of piezoelectric ceramic vibrator is the maximum corresponding loudspeaker current value of anti-resonance frequency.That is, current value is set to minimum of a value.

Particularly, judged whether to satisfy the condition (step S40) of Ih 〉=Ia#-50mA.Why the value that has deducted 50mA with the loudspeaker electric current I a# that goes out from last computation compares, and is because considered the change of skew as current value.

That is, deducted more than or equal to the loudspeaker electric current I a# that goes out from last computation under the situation of value of 50mA being judged as the loudspeaker electric current that calculates specifically, entered into step S41.In other words, the loudspeaker electric current I a# that the loudspeaker electric current that calculates specifically and last computation are gone out compares, and judges whether the loudspeaker current value that calculates specifically rises by reducing frequency, be judged as under the situation of rising, be judged as in the scope of resonant frequency and anti-resonance frequency.

Then, in step S41, CPU60 judges whether the value Ih of the loudspeaker electric current that calculates specifically is below the 100mA.

When in step S41, the value Ih of the loudspeaker electric current that calculates specifically be 100mA following the time, frequency is deducted 350Hz (step S42).Under the little situation of the value Ih that is judged as the loudspeaker electric current,, frequency is increased adjustment owing to can think that current frequency is positioned near the anti-resonance frequency (f (2)).

Then, will to adjust setting state be reduction pattern (step S43) to CPU60.

Then, the CPU60 loudspeaker electric current I h that will calculate specifically is set at loudspeaker electric current I a# last time (step S44).

Then, CPU60 finishes processing.Handle by this, the frequency of the electric power that can supply with to loudspeaker is from the frequency near anti-resonance frequency, adjust to greater than 300mA, smaller or equal to the corresponding target frequency of the loudspeaker electric current of 360mA.

As the value Ih that in step S41, is judged as the loudspeaker electric current that calculates specifically during, judge whether smaller or equal to 300mA (step S45) greater than 100mA.

If the value of being judged as Ih is smaller or equal to 300mA in step S45, then CPU60 deducts 70Hz (step S46) with frequency.Under the situation of the value Ih of loudspeaker electric current less than desired value, owing to can think that current frequency is a bit larger tham target frequency, so, frequency is reduced to adjust.

Then, it is reduction pattern (step S43) that CPU60 will adjust setting state, and the loudspeaker electric current I h that calculates specifically is set at loudspeaker electric current I a# last time (step S44), and end process.Handle by this, can from adjust near the frequency of anti-resonance frequency with greater than 300mA, smaller or equal to the corresponding target frequency of the loudspeaker electric current of 360mA.

On the other hand, when the value of being judged as Ih in step S45 is not below or equal to 300mA, during promptly greater than 300mA, whether the value Ih that judges the loudspeaker electric current that calculates specifically is smaller or equal to 400mA (step S47).

When the value of being judged as Ih was smaller or equal to 400mA in step S47, it was inching pattern (step S48) that CPU60 will adjust setting state.Then, the loudspeaker electric current I h that calculates specifically is set at loudspeaker electric current I a# last time (step S44), end process then.By this processing, be judged as under the situation of current frequency near target frequency, by inching frequency under inching pattern described later, can be more reliably from adjust near the frequency of anti-resonance frequency with greater than 300mA, smaller or equal to the corresponding target frequency of the loudspeaker electric current of 360mA.

On the other hand, when the value of being judged as Ih in step S47 is not below or equal to 400mA, during promptly greater than 400mA, whether the value Ih that judges the loudspeaker electric current that calculates in current reduction mode treatment is smaller or equal to 450mA (step S49).

In step S49, under the situation of the value of being judged as Ih smaller or equal to 450mA, frequency is added 70Hz (step S50).Be a bit larger tham at the value Ih of loudspeaker electric current under the situation of desired value, owing to can think that current frequency is slightly smaller than target frequency, so, frequency is reduced to adjust.

Then, will adjust setting state is rising pattern (step S51), and current loudspeaker electric current I h is set at loudspeaker electric current I a# last time (step S44), and end process.Handle by this, can from adjust near the frequency of anti-resonance frequency with greater than 300mA, smaller or equal to the corresponding target frequency of the loudspeaker electric current of 360mA.

On the other hand, the value of being judged as Ih is not below or equal to 450mA in step S49, promptly under the situation greater than 450mA, and error process (step S57).Then, end process.Under this situation, flow through out of contior electric current owing to flowing through unusual electric current as the loudspeaker electric current, being judged as, so error process.

On the other hand, the value that is judged as the loudspeaker electric current that calculates specifically in step S40 has deducted less than the loudspeaker electric current I a# that goes out from last computation under the situation of value of 50mA, and CPU60 makes to handle and enters into step S52.The loudspeaker electric current I a# that the loudspeaker electric current that calculates specifically and last computation are gone out compares, judge by reducing frequency, whether the loudspeaker current value that calculates specifically rises, and being judged as under the situation that the loudspeaker current value descended, can think the situation that frequency becomes littler than resonant frequency.Under this situation, according to the loudspeaker current value, determination frequency has reduced much degree from resonant frequency.

In step S52, CPU60 judges that whether the value of the loudspeaker electric current that calculates specifically is smaller or equal to 250mA.

Then, be judged as in step S52 under the situation of value smaller or equal to 250mA of the loudspeaker electric current that calculates specifically, CPU60 deducts 350Hz (step S53) with frequency.

Then, it is rising pattern (step S56) that CPU60 will adjust setting state, and the loudspeaker electric current I h that calculates specifically is set at loudspeaker electric current I a# last time (step S44), and end process.

On the other hand, be judged as in step S52 under the situation of value greater than 250mA of the loudspeaker electric current that calculates specifically, CPU60 judges that whether the value Ih of the loudspeaker electric current that calculates specifically is smaller or equal to 450mA (step S54).

Under the situation of the value of being judged as Ih smaller or equal to 450mA, CPU60 adds 100Hz (step S55) with frequency in step S54.

In above-mentioned step S52 and S54, according to the loudspeaker current value, the value that is divided into the loudspeaker electric current is smaller or equal to the situation of 250mA with greater than 250mA, smaller or equal to the situation of 450mA.As shown in Figure 5, little for the frequency characteristic of the oscillator 20 under the little situation of frequency ratio resonant frequency near its impedance of frequency of resonant frequency, big away from its impedance of frequency of resonant frequency.Therefore, under the situation of value smaller or equal to 250mA of loudspeaker electric current, owing to think the frequency far away apart from resonant frequency, so, so that the mode that frequency ratio changes significantly adjusts, the value of loudspeaker electric current greater than 250mA, situation smaller or equal to 450mA under owing to think frequency near resonant frequency, so, so that the mode that frequency ratio changes is adjusted lessly.

On the other hand, the value of being judged as Ih is not smaller or equal to 450mA, promptly under the situation greater than 450mA in step S54, error process (step S57).Then, end process.Under this situation, flow through out of contior electric current owing to flowing through unusual electric current as the loudspeaker electric current, being judged as, so error process.

(rising pattern)

With reference to Figure 10, in the processing of rising pattern, at first, the loudspeaker electric current I h that calculates specifically and the loudspeaker electric current I a# that last computation is gone out have been added that the value of 50mA compares, judged that whether the loudspeaker electric current I h that calculates has specifically added the value of 50mA smaller or equal to the loudspeaker electric current I a# that last computation is gone out.

Particularly, judge whether to satisfy the condition (step S60) of Ih≤Ia#+50mA.The loudspeaker electric current I a# that has carried out and last computation is gone out has added the comparison of the value of 50mA, as the change of current value and considered skew.

Promptly, judge that whether the loudspeaker electric current calculate has specifically added the value of setting less than the loudspeaker electric current that last computation is gone out, added smaller or equal to the loudspeaker electric current I a# that last computation is gone out under the situation of value of 50mA being judged as the loudspeaker electric current that calculates specifically, made to handle to enter into step S61.In other words, the loudspeaker electric current I a# that the loudspeaker electric current that calculates specifically and last computation are gone out compares, and judges whether the loudspeaker current value that calculates specifically reduces by increasing frequency, being judged as under the situation about having reduced, be judged as frequency in the scope of resonant frequency and anti-resonance frequency.

On the other hand, the value that is judged as the loudspeaker electric current that calculates specifically in step S60 has added greater than the loudspeaker electric current I a# that last computation is gone out under the situation of value of 50mA, has made to handle to enter into step S72, error process.Then, end process.Promptly, the loudspeaker electric current I a# that the loudspeaker electric current that calculates specifically and last computation are gone out compares, and judges whether the loudspeaker current value that calculates specifically reduces by increasing frequency, under the situation that is judged as the increase of loudspeaker current value, think the situation that frequency becomes bigger than anti-resonance frequency.Under this situation, because frequency has significantly departed from the frequency range of target, so error process.

Because the processing of step S61～step S71 is identical with the processing of step S41 illustrated in fig. 9～S51, so do not repeat its detailed explanation.That is, adjust frequency according to the loudspeaker current value.

In addition, in step S69, be judged as under the situation of value Ih greater than 450mA of the loudspeaker electric current that calculates by current processing error process (step S72).Then, end process.Under this situation, flow through out of contior electric current owing to flowing through unusual electric current as the loudspeaker electric current, being judged as, so error process.

(inching pattern)

With reference to Figure 11, in the processing of inching pattern, judge that at first whether the loudspeaker electric current I h that calculates specifically is smaller or equal to 100mA (step S82).

In step S82, be judged as under the situation smaller or equal to 100mA error process (step S83).Then, end process.In the arbitrary patterns of reduction pattern, rising pattern, inching pattern, owing to, be not set at the inching pattern, so under the situation of loudspeaker current value that calculates specifically smaller or equal to 100mA as long as loudspeaker electric current I h is not more than 100mA, think and fault has taken place, error process.

On the other hand, in step S82, be judged as under the situation about not being smaller or equal to 100mA, promptly be judged as in step S82 under the situation of value Ih greater than 100mA of the loudspeaker electric current that calculates specifically, whether the value Ih that judges the loudspeaker electric current that calculates specifically is greater than 100mA and smaller or equal to 280mA (step S84).

The value Ih that is judged as the loudspeaker electric current that calculates specifically in step S84 deducts 170Hz (step S85) greater than under 100mA and the situation smaller or equal to 280mA with frequency.Be slightly smaller than at the value Ih of loudspeaker electric current under the situation of target frequency,, frequency reduced to adjust owing to think that current frequency is a bit larger tham target frequency.

Then, will adjust setting state is reduction pattern (step S86), the loudspeaker electric current I a# (step S87) that the loudspeaker electric current I h that calculates specifically is set at, and end process.

On the other hand, the value Ih that is judged as the loudspeaker electric current that calculates specifically in step S84 is not greater than under 100mA and the situation smaller or equal to 280mA, promptly be judged as under the situation greater than 280mA, whether the value Ih that judges the loudspeaker electric current that calculates specifically is greater than 280mA and smaller or equal to 340mA (step S88).

The value Ih that is judged as the loudspeaker electric current that calculates specifically in step S88 deducts 17Hz (step S89) greater than under 280mA and the situation smaller or equal to 340mA with frequency.Be slightly less than at the value Ih of loudspeaker electric current under the situation of desired value, owing to think that current frequency is slightly less than target frequency, so turn frequency slightly down.

Then, will adjust setting state is inching pattern (step S90).Then, end process.Handle by this, can be adjusted into from frequency near anti-resonance frequency move closer to greater than 340mA, smaller or equal to the corresponding target frequency of the loudspeaker electric current of 360mA.

On the other hand, the value Ih that is judged as the loudspeaker electric current that calculates specifically in step S88 is not greater than under 280mA, the situation smaller or equal to 340mA, promptly under the situation greater than 340mA, whether the value Ih that judges the loudspeaker electric current that calculates specifically is greater than 340mA and smaller or equal to 360mA (step S91).

The value Ih that is judged as the loudspeaker electric current that calculates specifically in step S91 does not does not add and subtract frequency greater than under 340mA and the situation smaller or equal to 360mA, and will adjust setting state is inching pattern (step S90).Then, end process.Because current frequency is included in range of target frequencies, so the mode that is included in this frequency range according to frequency is adjusted.

On the other hand, the value Ih that is judged as the loudspeaker electric current that calculates specifically in step S91 is not greater than under 340mA and the situation smaller or equal to 360mA, promptly be judged as under the situation greater than 360mA, whether the value Ih that judges the loudspeaker electric current that calculates specifically is greater than 360mA and smaller or equal to 400mA (step S92).

The value Ih that is judged as the loudspeaker electric current that calculates specifically in step S92 adds 17Hz (step S93) greater than under 360mA and the situation smaller or equal to 400mA with frequency.At the value Ih of loudspeaker electric current under the situation of desired value owing to think that current frequency is slightly less than target frequency, so, turn frequency a little down.

Then, will adjust setting state is inching pattern (step S90).Then, end process.Handle by this, can be adjusted into from frequency near anti-resonance frequency move closer to greater than 340mA and smaller or equal to the corresponding target frequency of the loudspeaker electric current of 360mA.

On the other hand, the value Ih that is judged as the loudspeaker electric current that calculates specifically in step S92 is not greater than under 360mA and the situation smaller or equal to 400mA, promptly be judged as under the situation greater than 400mA, whether the value Ih that judges the loudspeaker electric current that calculates specifically is greater than 400mA and smaller or equal to 460mA (step S94).

The value Ih that is judged as the loudspeaker electric current that calculates specifically in step S94 adds 50Hz (step S95) greater than under 400mA and the situation smaller or equal to 460mA with frequency., under the situation of desired value,, frequency is reduced to adjust at the value Ih of loudspeaker electric current owing to think that current frequency is slightly less than target frequency.

Then, will adjust setting state is rising pattern (step S96), and the loudspeaker electric current I h that calculates specifically is set at loudspeaker electric current I a# last time (step S87), and end process.

On the other hand, the value Ih that is judged as the loudspeaker electric current that calculates specifically in step S94 is not greater than under 400mA and the situation smaller or equal to 460mA, promptly is judged as under the situation greater than 460mA error process (step S97).Then, end process.Under this situation, flow through out of contior electric current owing to flowing through unusual electric current as the loudspeaker electric current, being judged as, so error process.

Referring again to Fig. 6, in step S5, be judged as after any one pattern of the reduction pattern carried out as adjustment modes, rising pattern, inching pattern, judge whether at error process (step S6).

Just in step S6, be judged as under the situation of error process, enter into step S9.

Then, judged whether to carry out the fault processing (step S9) of stipulated number.

In step S9, be judged as under the situation of fault processing of the number of times that do not put rules into practice, make to handle to turn back to step S3, carry out the processing of above-mentioned steps S3～S6 repeatedly.

Owing to be judged as in step S9 under the situation of the fault processing of having carried out stipulated number, error condition continues, and stops to handle (step S10) so CPU60 carries out.That is, CPU60 sends the indication that the ultrasonic vibration that makes oscillator 20 stops to vibration unit control part 62, vibration unit 70.

Be judged as under the situation that is not fault processing in step S6, the adjustment (step S8) that judges whether to be through with is being judged as under the situation of end, makes to handle to enter into step S11.

On the other hand, be judged as under the still unclosed situation of adjustment, CPU60 makes to handle and turns back to step S4, before finishing adjustment, carries out the processing of step S4～S8 repeatedly.

Particularly, during the oscillator 20 of CPU60 in control vibration unit 70, carry out continuously and adjust, then, under the situation of the indication that is transfused to the control that stops vibration unit 70, be judged as to adjust and finish, make to handle to enter into step S11.

In step S11, carry out by wet fog generation processing described later or dry fog and generate the processing that processing generates water smoke.Then, in step S12, be judged as finish during water smoke generates before, proceed this water smoke and generate and handle, be judged as when finishing during water smoke generates end process.

In embodiments of the present invention, carry out reduction pattern, rising pattern, these 3 kinds of patterns of inching pattern,, be adjusted to and detect greater than 340mA, smaller or equal to the target frequency of the loudspeaker electric current of 360mA as an example.

Then, when carrying out the adjustment of this each pattern, carry out the preceding affirmation of adjustment by the adjustment of each pattern and handle (step S4).

As described above, when before adjustment, confirming in the processing, in the time of 32msec, calculate the mean value of No. 16 loudspeaker electric currents, and calculate mean value poor of the loudspeaker electric current in time with the 32msec of last time, it is little to be judged as the loudspeaker difference between currents, promptly almost do not have under the situation of change, carry out based on the adjustment of this loudspeaker electric current and handle.

By confirming to handle before this adjustment of execution before adjustment modes begins, the result that can not change according to the electric current that happens suddenly carries out to adjust and handles, and carries out the adjustment processing based on stable loudspeaker electric current, thereby can carry out the high adjustment processing of precision.

And, handle owing to carry out adjustment according to the frequency characteristic of oscillator 20, handle so can carry out the high adjustment of precision.

In addition, in before adjustment, confirm handling, the time of having enumerated 32msec as an example, but the above-mentioned time be an example, can freely design.And, the average situation that calculates 16 testing results in order to calculate the loudspeaker electric current is illustrated, but is not limited to 16 times, can freely design number of times.And though set the threshold to 50mA, the value of being not limited thereto can be set at optimal value.

In the present embodiment, make the time span of the unit interval of water smoke maker 100 supplying water mists, adjust the amount of the water smoke of being supplied with by change.Wherein, make the time of water smoke maker 100 supplying water mists, be meant that being in oscillator 20 in water smoke maker 100 becomes the state of ultrasonic resonator and the time that water smoke valve 59 becomes out the state of state.In addition, said here " time span of unit interval " is meant, the time span of the unit interval in during water smoke generates.

In washing machine 200, in order to make water smoke growing amount difference, water smoke maker 100 also can have the different many groups oscillator of size or quantity, by changing the group of the oscillator that vibrates based on ultrasonic wave electric power, the water smoke amount that the Request for Change bit time is supplied with.

(the control content of the vibration unit in the dry fog step)

With reference to Figure 16, the control content to vibration unit 70 in the dry fog step is described.

At first, in step S101, carry out feedwater to ultrasonic horn.Particularly, CPU60 opens water smoke with water-supply valve 44, from the leading section feedwater of water smoke water hose 210 to anterior ultrasonic horn 134.

In step S102, CPU60 judges whether the feedwater to ultrasonic horn finishes.Can whether pass through official hour (having finished) according to for example becoming out state with water-supply valve 44, carry out this judgement from water smoke by the predefined time of water smoke water hose 210 to the feedwater of the leading section of anterior ultrasonic horn 134.

When being judged as the feedwater of having finished to ultrasonic horn, CPU60 makes to handle and enters into step S103.

In step S103, CPU60 is the higher limit of predefined high frequency side in washing machine 200 with the frequency setting of the pwm signal of driver 26 outputs, makes then to handle to enter into step S104.

In step S104, CPU60 controls vibration unit 70, and its vibration frequency with the higher limit of the high frequency side set in step S103 is vibrated, and makes then to handle to enter into step S105.

In step S105, CPU60 judges whether the duration of the control of carrying out with the vibration frequency of current vibration unit 70 passed through 10msec, being judged as under the situation of having passed through, makes to handle to enter into step S106.

In step S106, CPU60 detects the loudspeaker electric current I d in this moment, makes then to handle to enter into step S107.

In step S107, CPU60 judges that if whether detected loudspeaker electric current I d more than or equal to 350mA, then makes handle enter into step S109 more than or equal to 350mA in step S106, if be judged as Id less than 350mA, then makes to handle to enter into step S108.

In step S108, CPU60 will reduce 35Hz to be upgraded the controlled frequency of vibration unit 70, makes then to handle to turn back to step S105.

By the processing of step S105～step S108, every 10msec reduces 35Hz for the controlled frequency of vibration unit 70.Thus, as reference Fig. 5 explanation,,, move closer to target frequency from being set at the higher limit between resonant frequency and the anti-resonance frequency to the controlled frequency of vibration unit 70.

Be judged as loudspeaker electric current I d when having reached 350mA, CPU60 will increase 500Hz to the controlled frequency of vibration unit 70 in step S109, make then to handle to enter into step S110.

In step S110, CPU60 judges the higher limit that whether controlled frequency of vibration unit 70 has been reached high frequency side, being judged as when also not reaching, makes to handle to enter into step S111, being judged as when reaching, makes to handle to enter into step S112.

In step S111, CPU60 waits for the process of 50msec, then processing is turned back to step S109.

More than, by the processing of step S109～step S111, the controlled frequency of vibration unit 70 is controlled so as to, and after loudspeaker electric current I d became the such value of 350mA, every 50msec increased 500Hz.

Then, be judged as controlled frequency to vibration unit 70 when having reached the higher limit of high frequency side (among the step S110 for being), CPU60 waits for the process of 100msec in step S112, then processing is turned back to step S101.

In the dry fog step of above explanation, is that unit progressively reduces to the controlled frequency of vibration unit 70 with 35Hz from the higher limit of high frequency side, then, when loudspeaker electric current I d has reached 350mA, to the every 50msec rising of the higher limit of high frequency side 500Hz, then, when controlled frequency reaches the higher limit of high frequency side, standby 100msec, then, in step S101～step S108, making controlled frequency is that unit reduces gradually from the higher limit of high frequency side with 35Hz to the low frequency side.

That is, in the dry fog step, the situation that the loudspeaker electric current is become the 1st current value (being 350mA in the present embodiment) that is predetermined rises controlled frequency as condition.Thus, water smoke maker 100 becomes the situation of the 1st current value according to the loudspeaker electric current, being controlled so as to will become state that the dither that utilizes oscillator 20 begins supplying water mist as condition, improve controlled frequency, become the state that stops in fact to oscillator 20 supply capabilities.

Thus, do not need to be provided with the operation that to each oscillator 20 decisions are used to generate the optimum frequency of water smoke, can realize making water smoke maker 100 to supply with the controls of a certain amount of water smoke to a certain degree.

Therefore, can not make the dry fog step long-term, can make water smoke maker 100 supply with the water smoke of appropriate amount.

In addition, after also can being substituted in the loudspeaker electric current and becoming the 1st current value, controlled frequency is risen, stop the stipulated time (for example 100msec) with supplying with to the electric power of vibration unit 70 and be controlled to.

In the present embodiment, according to becoming the 1st current value as condition with the loudspeaker electric current, the mode that controlled frequency is risen is controlled, but also can be according to after becoming the 1st electric current, controlled frequency kept the certain hour that is predetermined (for example 100msec etc.) under this state, the mode that controlled frequency is risen is controlled.

(the heater control in the drying process)

As described above, the driving of CPU60 control heater 50, and, control drying fan 52.Thus, by the rotation of the air after heater 50 heating, be fed in the tank 214 through ajutage 212 by drying fan 52.Thus, in washing machine 200, carry out the washings in the tank 214 is carried out dry drying process.

In above-mentioned drying process, by oscillator 20 is carried out suitable vibration control, in tank 214, supplying water mist on one side is Yi Bian make the washings drying.Thus, can make dried washings become soft.

In addition, by send into heated air in tank 214, the temperature that is located near the water smoke maker 100 the tank 214 also can rise.

Given this, in washing machine 200, in above-mentioned drying process,, carry out the drive controlling of heater 50 according to the detected temperatures of thermistor 49.Thermistor 49 is used for directly or indirectly detecting the temperature of above-mentioned oscillator 20, for example be arranged on water smoke maker 100 near.

With reference to Figure 17, the content of the drive controlling processing of heater 50 is described.

In step SA10, CPU60 judges whether the detected temperatures T of heater 49 has surpassed predefined the 1st temperature T X1 (for example 70 ℃), is being judged as under the situation about having surpassed, and makes to handle to enter into step SA20.On the other hand, be under the situation below the TX1 being judged as detected temperatures T, make to handle to enter into step SA40.

In step SA20, CPU60 stops the driving to heater 50, makes to handle to enter into step SA30.

In step SA30, CPU60 reports the state that has stopped the driving of heater 50, and processing is turned back to step SA10 by showing specific displaying contents etc.Such demonstration for example can be carried out in guidance panel 36.

In step SA40, CPU60 judges whether detected temperatures T becomes below the 2nd temperature T X2 (for example 60 ℃), becomes the 2nd temperature T X2 when following being judged as, and makes to handle to enter into step SA50.On the other hand, be judged as detected temperatures T when having surpassed the 2nd temperature T X2, CPU60 makes to handle and turns back to step SA10.

In step SA50, CPU60 (under situation about having stopped the driving of heater 50) begins the driving to heater 50 once more, makes then to handle to enter into step SA60.

In step SA60, CPU60 reports heater 50 driven states by showing specific displaying contents etc., makes then to handle to turn back to step SA10.Wherein, such demonstration for example can be carried out in guidance panel 36.

In the heater control of above explanation, when the detected temperatures T of thermistor in drying process 49 has surpassed the 1st temperature T X1, stop driving to heater 50, and under the detected temperatures T of thermistor 49 becomes situation below the 2nd temperature T X2 lower than the 1st temperature, restart driving to heater 50.

Also can replace thermistor 49, and detect the temperature of oscillator 20 indirectly, carry out and add thermal control according to the detected temperatures of thermistor 48.That is, can replace the detected temperatures of thermistor 49, and, carry out heater control according to the detected temperatures of thermistor 48.Thus, can omit thermistor 49, cut down the component parts of washing machine 200.

In addition, in the control of above-mentioned heater, the both sides that the driving of heater is stopped and restarting that reported (demonstration), but be not limited thereto, also can only report stop or driving restart (or situation about driving).

According to present embodiment,, stop the vibration of this ultrasonic element in ultrasonic element, to have flow through certain electric current as condition.Therefore, can when having reached certain vibrational state, ultrasonic element stop the vibration of ultrasonic element.

Thus, in washing machine, can in decision, not spend for a long time, and be not subjected to the influence ground of each ultrasonic element characteristic, generate the water smoke of appropriate amount the optimum frequencies such as resonant frequency of each ultrasonic element.

[the 2nd embodiment]

(schematic configuration)

With reference to Figure 18 and Figure 19, the washing machine 200A of present embodiment has the structure identical with the washing machine 200 of the 1st embodiment except the structure of special marking.

In washing machine 200A, by become at circulating pump 46 ON during open water smoke with water-supply valve 44, will supply to water smoke maker 100 through the water that circulating pump 204 draw up.Thus, the water in the tank 214 is blown as water smoke repeatedly and is paid to washings.

Though in Figure 18 and Figure 19, only illustrating the water route of giving of the use that is in the suds, in fact, in washing machine 200A, being provided with the desiccant water route of giving in addition.Drying use to water route be make running water by built-in detergent box 222 give water unit 220, and be fed directly to the path of water smoke with water-supply valve 44.Therefore, washing machine 200A also has dry with water-supply valve (not shown) be located at this drying and use to water unit (not shown) with the drying between the water-supply valve 44 with water-supply valve and water smoke.

Washing machine 200A also can constitute, and uses the water of giving in the water unit (not shown) directly to supply to the structure of tank 214 by feed pipe 208 drying.

Washing machine 200A can also constitute, and supplies with the structure of water to tank 214 from other feed pipes (not shown) that are different from feed pipe 208.

In washing machine 200A, also can give between water unit 220 and the circulation nozzle 240, the valve (not shown) of circulation usefulness is set.Under this situation, circulating pump 46 become OFF during, this valve becomes closed condition, is back to circulating pump 204 with the water in the unit 220 that prevents to feed water.

In washing machine 200A, circulation nozzle 240 is connected with giving water unit 220, but not necessarily, circulation nozzle 240 also can directly be connected with water smoke water hose 210.Under this situation, being the moment of ON at circulating pump 46, is not to open the control of water smoke with water-supply valve 44.

In washing machine 200A, circulating pump 46 supplies to the water in the tank 214 in the water unit 220 by loop hose 204.Thus, in washing machine 200A, when carrying out the drive controlling of circulating pump 46, open water smoke water-supply valve 44, and close water-supply valve 42.

(water smoke control sequential)

With reference to Figure 20, the control content of the washing procedure carried out in washing machine 200A is described.

In the washing procedure (during the washing) of standardization program, carry out " feedwater ", " immersion ", " water supply (1) ", " washing (1) ", " water supply (2) ", " washing (2) ", " water supply (3) ", " washing (3) ", " draining " successively.Then, enter into rinsing process.

In the present embodiment, so-called " program " is meant the combination of a series of processing of the washings execution that the user is dropped into.

The waveform that is recited as " main feedwater portion " among Figure 20 has been represented the open and-shut mode of water-supply valve 42.It is corresponding with " ON " to open state, and it is corresponding with " OFF " to close state.

The waveform that is recited as " circulating pump " has been represented the ON/OFF of circulating pump 46.When the ON state, supply with to tank 214 once more by loop hose 204 and circulation nozzle 240 by will the flow through water of drainpipe 238 of circulating pump 46.

The waveform that is recited as " wet fog control " has represented whether carrying out wet fog control described later.

The waveform that is recited as " motor " has been represented the action of drum motor 54.OFF STA representation drum motor 54 not driven states.In addition, " L_ON " expression head roll motor 54 is in order to make the left-handed then state that drives of rotating cylinder, " R_ON " expression head roll motor 54 state in order to make rotating cylinder dextrorotation then to drive.

In immersion and each washing procedure (being called " during the washing " during with such operation), circulating pump 46 becomes the ON state.Circulating pump 46 become the ON state during in, carry out wet fog control.

During this washing,, in the feedwater operation, in tank 214, supply with and only can soak the water of the part of washings in order to be sprayed on a large scale on the washings by the water smoke that water smoke maker 100 generates.

As shown in figure 20, in " washing (3) ", can switch the ON/OFF of circulating pump 46 per specified time limit.Its reason is, when carrying out the operation of " washing (3) ", thinks washings by fully wetting, in this operation, always do not need to blow to washings and pays the water (having dissolved the water of washing agent) that has atomized.

For example, in standardization program, during " washing (3) " in ON during " j1 " be set at 14 minutes, " j2 " during the OFF is set at 22 minutes, it is carried out repeatedly.

With reference to Figure 21, to wet fog among Figure 20 be controlled to be ON during the sequential of frequency adjustment control describe.

When circulating pump 46 becomes ON, the control of beginning wet fog.In Figure 21, represent with " Twm " during the wet fog control.During this time Twm be to each program (standard, immersion etc.) and the operation that in each program, comprises (washing (1), washing (2) etc.) predesignate during.For example, in " washing (1) " operation of standardization program, during Twm be 5 minutes.

In Figure 21, the needed time of the frequency adjustment of oscillator 20 control (adjustment) is represented with " TA ".By this control, obtain the optimum value of the driving frequency of oscillator 20.In Figure 21, represent with " TB " based on the control period of optimum value.

In control period TB because oscillator 20 driven with optimum value, so well (fully) generate water smoke.But, in control period TB, because the variation of the washing agent water yield etc. can make load change, so preferred execution error simultaneously monitors control.Error monitoring control also can be the adjustment processing same with frequency adjustment control.

Because control period Twm fixes as described above, so it is short more to adjust time T A, TB is long more during the Optimal Control.That is, if more early explore optimum frequency, then generate well water smoke during long more.Therefore, in order to improve the clean precision of washings, finishing frequency adjustment control as early as possible is necessary condition.

Given this, in the present embodiment, carry out following processing.That is, as shown in figure 21, after wet fog control beginning through the stipulated time (for example 2 seconds) before, do not begin frequency adjustment control.Like this, in the present embodiment, frequency adjustment control is not carried out simultaneously with the beginning of wet fog control, and is carrying out through after the stipulated time.This stipulated time is represented to be driven from circulating pump 46, is fed into the needed time of leading section of the anterior ultrasonic horn 134 of oscillator 20 to water, has adopted the predefined time.Thus, can under the roughly certain state of the load of oscillator 20, begin frequency adjustment control.As a result, can finish frequency adjustment control as early as possible.That is, can explore the optimum frequency of oscillator 20 with the short time.

In addition,, begun the driving of oscillator 20, also can when wet fog control begins, carry out the driving of oscillator 20 though in Figure 21, begin with frequency adjustment control.

In washing machine 200A, Twm fixes by the combination of each program and operation during the wet fog control, but also can will reset in the elapsed time under the situation that is judged to be the fault processing of having carried out stipulated number, again from beginning to carry out wet fog control at first.

The washing machine 200A of present embodiment also can be during " feedwater " shown in Figure 20 in, carry out water smoke and give water management (aftermentioned).Particularly, in the washing feedwater, control water smoke, on the basis of common feedwater, also carry out feedwater based on water smoke.

With reference to Figure 22, water smoke is described to water management.When drying is opened with water-supply valve (not shown), also open water smoke with water-supply valve 44, carry out water smoke and give water management.In water smoke is given water management, also same with above-mentioned wet fog control, not to begin frequency adjustment control immediately, but through the stipulated time, for example begin control after 2 seconds.Thus, with above-mentioned same, owing to can become beginning frequency adjustment control under certain state at load to oscillator 20, so can finish frequency adjustment control as early as possible.

Like this, also carry out the water smoke feedwater during by the initial feedwater in program simultaneously, can soak washings in the initial period of program integral body.As a result, can improve the clean efficient of washings.

In addition, in washing machine 200A, also in the rinsing process that can behind washing procedure shown in Figure 20, carry out, carry out processing shown in Figure 21.

With reference to Figure 23, the control of the oscillator in the control of the water smoke carried out in washing machine 200A is described.Wherein, in the following description, be that example describes with wet fog control shown in Figure 21 (the water smoke control in during each washing).But, do not having under the situation of specified otherwise, be applicable to that also water smoke shown in Figure 22 is to water management.

With reference to Figure 23, at first, to ultrasonic horn feedwater (step SB1).Particularly, CPU60 opens water smoke water-supply valve 44 in the driving of beginning circulating pump 46.Thus, the water in the tank 214 is fed into to water unit 220 by loop hose 204.Then, the water that has dissolved washing agent is fed into the leading section of anterior ultrasonic horn 134 from water smoke water hose 210.Like this, carrying out wet fog when control, by circulating pump 46, loop hose 204, supply with water to water smoke maker 100 for water unit 220 and water-supply valve 44 etc.

And CPU60 begins the timing action of timer 64 in step SB1.

Give under the situation of water management at water smoke shown in Figure 22, CPU60 control is dry with water-supply valve (not shown) and water smoke water-supply valve 44, and both are opened.Thus, running water is fed into the leading section of anterior ultrasonic horn 14 from water smoke water hose 210.Like this, feeding water water smoke when control, from drying with water-supply valve (not shown), dry with supplying with water with water-supply valve 44 etc. to water smoke maker 100 for water unit (not shown) and water smoke.

Then, judge whether (detection) has finished the feedwater (step SB2) to loudspeaker.Finished under the situation of the feedwater of loudspeaker when in step SB2, being judged as, entered into step SB3.Particularly, open with water-supply valve 44,, judge to the stipulated time of the leading section of the anterior ultrasonic horn 134 that fed water by water smoke water hose 210 according to whether having passed through from water smoke.

That is, in washing machine 200A,, judge whether to have finished feedwater to loudspeaker according to waiting the predetermined time by experiment.

In addition, as long as can detect feedwater to oscillator 20 (specifically being the leading section of anterior ultrasonic horn 134), the basis of judgement is not limited to the time.For example, also watermeter (not shown) can be set in water smoke water hose 210, by detecting the water yield of supplying with to water smoke maker 100, perhaps whether finished the feedwater that reaches the predetermined water level in the water smoke maker 100 by detecting, judge whether to have finished feedwater to loudspeaker.

Following processing mainly is the processing in the vibration unit control part 62.

In step SB3, carry out initial setting and handle.

Because handling, initial setting can adopt the contents processing that describes with reference to Fig. 7, so, in this not repeat specification.

Then, carry out the preceding affirmation of adjustment and handle (step SB4).

Because confirm to handle the same processing of content that can adopt with reference to Fig. 8 explanation before adjusting, so, in this not repeat specification.

Then, carry out adjustment modes and begin to handle (step SB5).

After the arbitrary patterns of in step SB5, having carried out reduction pattern as adjustment modes, rising pattern, inching pattern, judge whether just at error process (step SB6).

When during just in error process, making to handle to enter into step SB9 in step SB6, misjudgment handles whether be performed stipulated number (step SB9).

In step SB9, be judged as under the situation of fault processing of the number of times that also do not put rules into practice, make to handle to turn back to step SB3, repeat the processing of above-mentioned steps SB3～SB6.

In step SB9, be judged as under the situation of the fault processing of having carried out stipulated number,, stop to handle (step SB10) so carry out owing to be that error condition continues.That is, CPU60 sends to vibration unit control part 62 and makes vibration unit 70 stop the indication of the ultrasonic vibration of oscillator 20.

Be judged as in step SB6 under the situation of error process not, adjustment (step SB8) then judges whether to be through with.

Adjust also not knot if be judged as bundle, then turn back to step SB4, before finishing adjustment, the processing of execution in step SB4～SB8 repeatedly.

Particularly, vibration unit control part 62 continues to carry out and adjusts during the oscillator in the vibration unit 70 20 is controlled, in the indication of basis from CPU60, be transfused under the situation about stopping, be judged as to adjust and finish the indication of the control of vibration unit 70, and end process.

In embodiments of the present invention, carry out reduction pattern, rising pattern, these 3 patterns of inching pattern,, be adjusted to and detect greater than 340mA, smaller or equal to the target frequency of the loudspeaker electric current of 360mA as an example.

Then, when carrying out the adjustment of this each pattern, the preceding affirmation processing of adjustment (step SB4) is carried out in each adjustment of each pattern.

As described above, in before adjustment, confirming to handle, the time interval of every 32msec calculates the mean value of No. 16 loudspeaker electric currents, and calculate mean value poor of the loudspeaker electric current in time with the 32mSec of last time, under the situation little in the difference that is judged as the loudspeaker electric current, that promptly almost do not have to change, carry out based on the adjustment of this loudspeaker electric current and handle.

Handle by before adjustment modes begins, carrying out the preceding affirmation of this adjustment, can avoid carrying out the adjustment processing, handle, can carry out high-precision adjustment processing thereby can carry out based on the adjustment of stable loudspeaker electric current according to the result of the electric current change that happens suddenly.

Handle owing to carry out adjustment according to the frequency characteristic of oscillator 20, so, can carry out high-precision adjustment and handle.

In before adjustment, confirm handling, with time of 32msec be that example is illustrated, but the above-mentioned time be an example, can carry out freely designing.And, the average situation that calculates 16 testing results in order to calculate the loudspeaker electric current has been described, but has been not limited to 16 times, can carry out freely designing.In addition, set the threshold to 50mA, but the value of being not limited thereto can be set at best value.

In addition, the washing machine 200 of present embodiment also can carry out dry fog control in drying process.In the rear half stage of dried, carry out dry fog control for the wrinkle Zhe that reduces washings.That is, dry fog control is meant that the clothing that is used for after being dried etc. blows the control of paying water smoke.In such dry fog control, also can carry out and the same processing of above-mentioned wet fog control.
