Description
Technical field
The present invention relates to a kind of washing machine, the axle that is provided with in this washing machine roughly to be on horizontal direction or the incline direction is the swing roller that the center is rotated, and clothing installs in this swing roller, washs, rinsing, dehydrating operations.
Background technology
Existing washing machine generally is provided with: the input setup unit and the control module of the operation of swing roller, steel ladle, the metal support member that supports steel ladle, the washing machine pedestal that supports washing machine body, the motor that drives swing roller, setting washing machine.Swing roller is used to accommodate the clothing that will wash, and with roughly be on horizontal direction or the incline direction the axle be that the center is rotated.Steel ladle surrounds this swing roller from the outside, and is bearing in the washing machine body by suitable support unit.Control module is controlled mode of operation and the motor set from the input setup unit.By carrying out these controls, can carry out refined control to each strokes such as washing, rinsing, dehydrations.
But, enter into dehydration during stroke from washing stroke, adorning the clothing that also contains moisture when washing stroke finishes in the swing roller.When making rotary drum rotating in order to make these clothes dewaterings, because kind, quality and the shape of clothing have nothing in common with each other, clothing may be in imbalance state for rotatablely moving in the dehydration stroke.Like this, in the swing roller etc. very big vibration can take place, send very big noise.
To this, the open communique spy of Japan Patent opens the method for the abnormal vibrations that a kind of dehydration stroke that is used for detecting washing machine has been shown among the clear 61-98286.In this method, adorning clothing and cleaning solution and the swing roller that rotates is bearing in the inside casing in rotation mode freely, described inside casing is bearing in the housing of washing machine by buffer gears such as springs.Then, by the vibrating detector that is located on the housing mechanical oscillation of inside casing are detected.
In the dehydration stroke, at first carry out balance and obtain stroke, that is, motor carries out low speed rotation, drives rotary drum rotating, and the centrifugal force that relies on rotation to produce is adjacent on the internal face of swing roller clothing equably; Then, make swing roller make the dehydration stroke of rotation at a high speed again.If abnormal vibrations takes place, swing roller is stopped the rotation midway.
But, adopt above-mentioned device to constitute, in the process that clothing is averaged out, be adjacent under the mode in some of clothing, even exist unbalancely in the swing roller, the amplitude of mechanical oscillation is also very little.Like this, just can not detect abnormal vibrations.Yet, carry out high speed when rotating at swing roller, very big vibration just appears first, detect abnormal vibrations.Like this, actual carry out high speed rotation before, can not detect whether abnormal vibrations takes place.Therefore, after abnormal vibrations takes place, stop again, exist the danger that causes damage to clothing and washing machine, and will wait until that swing roller can waste a lot of times again before stopping.
In addition, the someone has proposed such washing machine abnormal vibrations detection method again recently, and this method can carry out detecting the abnormal vibrations that causes because of unbalance before the rotation at a high speed at swing roller, thereby carries out safety, high efficiency dehydrating operations.Concrete grammar is: be provided with the converter circuit that is used to drive the induction machine of rotary drum rotating and is used to drive this induction machine in the washing machine; Then, make washing stroke, the balance stroke that carries out low speed rotation that swing roller just changes/reverse and carry out the dehydration stroke of rotation at a high speed successively continuously.In such washing machine, when beginning with the balance stroke, just the output current virtual value to converter circuit detects.Then, calculate the current value difference, compare with the pre-set oscillating current setting value of crossing again, cross the oscillating current setting value, then sent vibratory alarm if surpass this from the current maxima and the current minimum of current effective value.One example of such abnormal vibrations detection method sees that the open communique spy of Japan Patent opens flat 6-170080.
Such method is to infer abnormal vibrations indirectly by the current effective value of induction machine, but the one-tenth of such deduction to premise be that the unbalance of clothing has embodiment in the current effective value of induction machine, and such imbalance state can cause abnormal vibrations.But the current effective value of induction machine changes except clothing unbalance, also is subjected to the influence of bearing and other mechanical part of induction machine.Therefore, adopt said method, must after having considered deviation, judge having or not of vibration by comparing again with the oscillating current setting value, so the mistake vibratory alarm that can take place much to there is no need, the situation that swing roller stops the rotation occurs too much.
Summary of the invention
Be provided with in the washing machine of the present invention: swing roller, steel ladle, the body that steel ladle is housed, washing machine pedestal, motor, vibration detecting unit, control module, waveform input circuit, the 1st output detection circuit 26 and the 2nd output detection circuit.Swing roller is packed into for clothing, and its rotary middle spindle is on level or the incline direction.Steel ladle is supported in the mode that can shake, and its inside is provided with rotation swing roller freely.Washing machine pedestal is set at the below of body, and body is supported.The motor-driven rotary drum rotating.Be provided with primary winding, secondary coil and magnetic in the vibration detecting unit, be set between steel ladle and the washing machine pedestal.Behind the voltage waveform of input regulation, when magnetic shook along with shaking of steel ladle, secondary coil can be to the motion corresponding voltage waveform of the 1st output detection circuit 26 outputs with magnetic in primary winding.The 1st output detection circuit 26 in addition after the rectification, is exported to control module with this output signal.In addition, the 2nd output detection circuit exports control module to after the output of the 1st output detection circuit 26 is amplified.By adopting above-mentioned device to constitute, only just can detect the vibration and the upper and lower displacement of the steel ladle that is built-in with swing roller accurately with a secondary coil.Therefore, not only vibration and abnormal sound that dehydration causes because of clothing is unbalance in the stroke can be prevented trouble before it happens, but also can detect the washings amount of input accurately.

The top of cover 7 is provided with the input setup unit 9 of operator scheme of being used to set washing machine 10 etc.In addition, the front lower place in the washing machine 10 is provided with control module 11, and the information that this control module 11 is accepted from setup unit 9 is controlled the operation of motor 5 grades according to such information again.Control module 11 is made of micro computer etc., and a succession of operating process such as washing, rinsing, dehydration, drying are controlled successively.
The bottom of steel ladle 3 is provided with the metal support parts 16 that are used to support steel ladle 3.Part at metal support parts 16 and washing machine pedestal is between the base plate 17, and the vibration detecting unit 18 of the vibration that is used to detect steel ladle 3 is installed.In addition, the top of vibration detecting unit 18 also can constitute and metal support parts 16 corresponding shapes.In other words, vibration detecting unit 18 is arranged between steel ladle 3 and the base plate 17.The below of body 10A is provided with the base of washing machine, and 10A supports with body.
As shown in Fig. 1 and Fig. 2, comprise coiler part 19 and axle 23 in the vibration detecting unit 18.Fig. 3 is the sectional view of vibration detecting unit 18.Coiler part 19 is made of primary winding 21 that is coaxial shape and secondary coil 22.The primary winding 21 of input usefulness is set at the inboard, and the secondary coil 22 of output usefulness is arranged on the outside.Axle 23 is made of nonmagnetic materials such as synthetic resin, and inside is provided with the magnetic 20 that is a shape.Axle 23 is configured to and can moves up and down vertically, runs through and mistake from the core of 2 coils 21,22 of coaxial shape.After adopting such formation, magnetic 20 can move according to the central part that rocks at coil 21,22 of steel ladle 3.
Position when here, the lower end of the magnetic 20 of axle in 23 is positioned at the winding scope of primary winding 21 is used as the reference position of spools 23 up-down vibration.The number of turns of secondary coil 22 is about 10 times of the number of turns of primary winding 21, and the length of magnetic 20 is longer than the coil windings width of secondary coil 22.
Fig. 4 is the wiring circuit figure of washing machine 10.The primary winding 21 of vibration detecting unit 18 is connected with the waveform input circuit 25 of the voltage waveform that is used to import regulation.Secondary coil 22 the 1st output detection circuit 26 is connected with control module 11.From a road being connected with control module 11 that branch between the 1st output detection circuit 26 and the control module 11 comes out through the 2nd output detection circuit 27.In addition, the 1st output detection circuit 26 is made of rectification circuit and the 1st smoothing circuit, and the 2nd output detection circuit 27 is made of amplifying circuit and the 2nd smoothing circuit.
Washing operation and motor 5 that 11 pairs of control modules are set from the input setup unit 9 of the mode of operation that is used to set washing machine 10 are controlled.Part in the control module 11 is made of micro computer 24, and waveform input circuit 25 utilizes the supply voltage (as 5V) that supplies in this micro computer 24 to form triangular wave, and this triangular wave is input in the primary winding 21.Like this, secondary coil 22 will be to the position corresponding output signal of the 1st output detection circuit 26 outputs with magnetic 20.The 1st output detection circuit 26 carries out rectification, smoothing processing with the output of secondary coil 22, and its output voltage is input to the A/D conversion terminal 28a of micro computer 24.In addition, the output voltage that carries out over commutation, smoothing processing by the 1st output detection circuit 26 is further amplified in the 2nd output detection circuit 27, smoothing processing, and the output voltage of the 2nd output detection circuit 27 is input to the A/D conversion terminal 28b of micro computer 24.
For this reason, preferably with the supply voltage of micro computer 24, be sent to waveform input circuit 25 supply voltage, and the 1st output detection circuit 26 in the supply voltage of rectification circuit be set on the identical voltage, and the supply voltage that constitutes the amplifying circuit in the 2nd output detection circuit 27 is set at than on the high voltage of these supply voltages.For instance, if the supply voltage of micro computer 24 grades is 5V, the supply voltage that constitutes the amplifying circuit of the 2nd output detection circuit 27 preferably be set at than its high 1.5V or more than, can be for example 6.5V.By carrying out after such voltage sets, the supply voltage that can make the high energy of output voltage after the amplification reach micro computer 24 is 5V.After the signal voltage level of the 2nd output detection circuit 27 being brought up on the mains voltage level of micro computer 24, can improve that the back will be described, be used to the detection resolution capability that the signal from the 2nd output detection circuit 27 carries out.
Fig. 5 is the performance plot that the 1st output with vibration detecting unit 18 of above-mentioned formation detects the 2nd output detection circuit 27.This characteristic there is shown the output voltage situation of change that the 1st output when the input of primary winding 21 being kept certain and making axle 23 (draw direction) or (compression direction) motion downwards up that is built-in with magnetic 20 detects the 2nd output detection circuit 27.Relation between displacement when more particularly, Fig. 5 shows axle 23 and carries out upper and lower displacement with respect to the reference position and the output voltage of the 1st output detection circuit the 26, the 2nd output detection circuit 27.
Working condition and effect to the output of the 1st in the vibration detecting unit 18 with above structure detection the 2nd output detection circuit 27 is described in detail below.As can be seen from Figure 5, between the output voltage of axle 23 the moving displacement amount that is built-in with magnetic 20 and the 1st output detection circuit 26, present more to the right certain relation of decline more in the scope of the 40mm of the about 10mm on draw direction to the compression direction.The scope here from the about 10mm of draw direction to compression direction 40mm be equivalent to pack into the swing roller 1 clothing, in washing stroke, also add sedimentation deformation weight range when reaching maximum load after the entry then.Because the output voltage detection range of the 1st output detection circuit 26 is big, also little for the voltage ramp rate of unit displacement amount, so be suitable for carrying out vibration detection.That is to say that by using the output voltage of the 1st output detection circuit 26, control module 11 particularly dewaters and can suitably detect the vibration situation in the stroke in a series of washing stroke.
On the other hand, the output voltage of the 1st output detection circuit 26 is also amplified by the amplifying circuit of the 2nd output detection circuit 27.That is the output voltage of the 2nd output detection circuit 27 comes voltage to obtain amplification compared with the output voltage of the 1st output detection circuit 26.Therefore, between the output voltage of axle 23 moving displacement amount that is built-in with magnetic 20 and the 2nd output detection circuit 27, almost in linear relation in the scope of the 10mm of about 10mm on draw direction to the compression direction, and on the position of the about 15mm on the compression direction, reach maximum.Sedimentation deformation weight range when the scope of the 10mm of about 10mm to compression direction from draw direction here and clothing install to the swing roller 1 is suitable.Because the detection range of the output voltage of the 2nd output detection circuit 27 is narrow but big for the voltage ramp rate of unit displacement amount, so be suitable for the amount of putting into the clothing (washings) in the swing roller 1 is detected.Also in other words, control module 11 utilizes the output voltage of the 2nd output detection circuit 27 to carry out high-precision test to laundry amounts.
When the washing machine that has an above-mentioned formation in use carries out laundry operations, the user at first opens gate body 7, drop into washings in swing roller 1, input setup unit 9 select operating modes and the input operation from the face side top that is located at washing machine 10 begins indication then.By carrying out such operation, washing machine 10 promptly begins to carry out and the corresponding operation of specified operator scheme, and is the operation of carrying out regulation according to the control of control module 11.When dropping into washings, steel ladle 3 sinks downwards accordingly with the washings amount of putting in the swing roller 1.
Because metal support parts 16 support steel ladle 3, vibration detecting unit 18 is installed between base plate 17 and the steel ladle 3, vibration detecting unit 18 is made of coiler part 19 that constitutes with a plurality of coils and magnetic 20 again, coiler part 19 is fixed on the base plate 17,20 of magnetics are fixed on the metal support parts 16 that are installed on the steel ladle 3, therefore, magnetic 20 also will be along with steel ladle 3 sinking be downwards moved downwards accordingly, and the output voltage of the 2nd output detection circuit 27 will be along with so mobile changing.Output voltage by pre-determining the 2nd output detection circuit 27 and the relation between the washings amount, control module 11 can detect the washings amount of input from the variable quantity of the output voltage of the 2nd output detection circuit 27.Then, control module 11 decides the time of the washing water yield or washing stroke etc. according to the washings amount that drops into, carry out successively then and the matched washing operation of washings amount.
Enter into dehydration during stroke from washing stroke, adorning the clothing of the moisture when containing washing stroke and finishing in the swing roller 1, control module 11 makes swing roller 1 rotate with the 1st rotating speed of regulation, to dewater.The 1st rotating speed here can be with washing stroke in identical rotating speed.Because kind, quality and the shape of clothing have nothing in common with each other, clothing rotatablely moving during for the 1st rotating speed may occur unbalance.Under such occasion, swing roller 1 can vibrate, and the steel ladle 3 of the portion that sets within it also will vibrate.When vibration takes place in steel ladle 3, magnetic 20 can move up and down accordingly with such vibration (shaking).The output voltage of the 1st output detection circuit 26 also can change according to its displacement, and control module 11 just can detect its vibration situation.
Control module 11 according to the output voltage of the 2nd output detection circuit 27 to controlling by input setup unit 9 predefined a succession of washing operations.And, in the dehydration stroke,, then drive swing roller 1 and rotate with the 2nd rotary speed (high rotation speed) greater than the 1st rotary speed by motor 5 if little from the output voltage generation extent of vibration of the 1st output detection circuit 26.On the other hand, if judge that extent of vibration is unusual degree, 11 of control modules stop the rotation motor 5, perhaps make motor 5 stop the rotation earlier, quicken again from the slow-speed of revolution, to eliminate the imbalance state of clothing.In addition, judging that 11 of control modules descend the rotary speed of motor 5 under the slight situation of extent of vibration, thereby reducing vibration and noise when dewatering rotation.Take after these measures, can suppress abnormal vibrations and extraordinary noise in swing roller 1 grade.The detail of such rotation control is opened the open communique spy of Japan Patent to be had among the 2005-230315 openly, so just be not repeated at this.
In addition, be arranged on the inboard though show the primary winding 21 of input side among Fig. 3, the secondary coil 22 of outlet side is arranged on the outside, coil 21,22 is coaxial shape and is arranged on a structure in the outside of shape magnetic 20, but in addition, also can resemble shown in Fig. 6 primary winding 21 is arranged on upside, secondary coil 22 is arranged on downside, constitutes shape in parallel; Perhaps conversely, primary winding 21 is located at downside, secondary coil 22 is arranged on upside, also constitute shape in parallel.That is primary winding 21 and secondary coil 22 also can be arranged on axle 23 the axial direction that inside is provided with magnetic 20.Adopt after such formation,, in secondary coil 22, also can induce voltage, reach the effect the same with the formation shown in Fig. 3 by making the axle 23 that is built-in with magnetic 20 movable up and down in the axial direction.
In addition, the number of turns of primary winding 21 or secondary coil 22 can change, and the magnifying power of the 2nd output detection circuit 27 also can change.Like this, when the output voltage by the 1st output detection circuit 26 carries out vibration detection or when the output voltage by the 2nd output detection circuit 27 carries out clothes amount detection, can will be used, thereby make characteristic reach best because of the different displacement of the specification of washing machine and the relation of output voltage.
Comprise in the vibration detecting unit 18: the primary winding 21 that is positioned at input side; Be arranged to coaxial shape with primary winding 21, be positioned at the secondary coil 22 of outlet side; Be arranged to be applied in the coil 21,22 and can move freely axle shape magnetic 20.After adopting this formation, can carry out magnetic coupling effectively between primary winding 21 and the secondary coil 22.In addition, because axle shape magnetic 20 is configured to be applied in the coil 21,22 and can moves freely, therefore, can induce the secondary voltage of the position relation that reflects between coil 21,22 and the magnetic 20 in the secondary coil 22 accurately.
In addition, control module 11 not only detects by the output of 26 pairs of secondary coils 22 of the 1st output detection circuit, but also by the 2nd output detection circuit 27 its output signal after amplifying is detected.After adopting this circuit to constitute, the secondary voltage that induces in 1 secondary coil 22 can be handled as 2 output voltages.For this reason, 1 secondary coil 22 of 11 usefulness of control module just can detect the vibration and the upper and lower displacement situation of the steel ladle 3 that is built-in with swing roller 1 accurately.By using such testing result, control module 11 just can make at the dehydration stroke and prevent trouble before it happens because of the vibration and the abnormal sound of the unbalance generation of clothing.In addition, the displacement that steel ladle 3 downward slight sinkings produce can also be detected, thereby the washings amount of input can be detected from the output voltage of the 2nd output detection circuit 27.Like this, the present invention just can provide a kind of low cost of manufacture, washing machine easy to use.
By only carrying out above-mentioned two kinds of detections respectively with a secondary coil 22, the structure of vibration detecting unit 18 can be simplified, and for this reason, vibration detecting unit 18 also can be realized miniaturization.And the yield rate of vibration detecting unit 18 also can improve.
In addition, though the rotating shaft 4 in the present embodiment is being arranged to downward-slopingly from face side to the direction of rear side of washing machine 10, in fact is arranged to horizontal direction and also is fine.And the 2nd output detection circuit 27 is located on the circuit board even the 1st output detects, the formation one also is fine.
As mentioned above, washing machine of the present invention directly detects by vibration detecting unit the vibration of steel ladle, prevent trouble before it happens because of the vibration and the abnormal sound of the unbalance generation of clothing so can make in the dehydration stroke, also can detect the laundry amounts in the swing roller simultaneously.Therefore, the present invention is at the family expenses with clothes washing and dehydrating function, professional with being exceedingly useful in the washing machine etc.
