The specific embodiment
Below the present invention will be described in detail for the contrast accompanying drawing:
Fig. 3 is the sensing device figure of the laundry amounts of washing machine of the present invention.This sensing device comprises following components: motor 12, by the main coil of motor 12 and the electric capacity between the secondary coil 13 with along with the variation of the voltage on the electric capacity is converted to the laundry amounts sense part that the survey electric installation 16 of pulse voltage data constitutes with signal, the control part that constitutes by data processing division 15 and the laundry amounts perception reference data that has configured and the logger of recording impulse voltage data time 17.Motor 12 is devices of the impeller of revolution washing machine, produces the pulse current that is caused by surplus electricity in motor, thereby comes the perception laundry amounts by this pulse current.The laundry amounts sense part plays the effect that the winding number that takes place is replaced with the signal of pulse voltage data mode on motor.The laundry amounts perception reference data that originally configured is arranged in the control part, compare with this reference data with by the pulse voltage data that the laundry amounts sense part is exported and judge laundry amounts, and the amount of decision washings.
Triac 14a, 14b, 14c, 14d is connected between motor 12 and the AC power 11, and control by control part by the AC current of triac arrival motor, so power supply by switching on to triac to motor 12 power supply, is surveyed electric installation 16 and is by the variation of the voltage on the electric capacity 13 voltage pulse output data.

Fig. 4 is the pulse voltage data and the time chart of washing loads among the present invention.Fig. 4 a and Fig. 4 b are situations many in laundry amounts and after a little while.
Motor 12 runnings were stopped power supply after several seconds, and this time, impeller can be because its own inertial continues rotation, if clothing is many, clothing and impeller can produce frictional force, and the winding number of impeller is also fewer thereupon; The winding number of impeller will increase to some extent when clothing is fewer on the contrary.
Contrast Fig. 5 explains operation workflow of the present invention below.
Phase I is in the assembling of washing machine, and the reference data of laundry amounts perception and a reference value and the no pulse voltage reference data of each amount are input to logger 17 the insides, i.e. s1.
The reference data of laundry amounts perception be in washing machine assembling under uncharge situation, carry out the laundry amounts sense operation, carry out sense operation at each laundry amounts, pulse voltage data and corresponding time handled being set at reference data by data processing division 15, its value is input to 17 li of loggers.
No pulse voltage reference data are to judge the value of final pulse voltage data, and pulse voltage does not exist in regular hour the inside under the situation that motor stops in other words, then think the value that motor 12 has stopped fully.
In second stage, at first, to put into clothing in the sink and intake again, inflow reaches the water level that detects laundry amounts to be stopped, data processing division 15 motor 12 that just comes into operation then, the running of motor 12 also drives impeller and rotates, i.e. s2.
In the phase III, the running of the motor 12 of second stage s2 is stopped power supply after several seconds, and this time, impeller can be because its own inertial continues rotation, if clothing is many, clothing and impeller can produce frictional force, so the winding number of impeller is also fewer thereupon; The winding number of impeller will increase to some extent when clothing is fewer on the contrary.Will cause pulse current this time, surveys electric installation 16 during this time voltage pulse output data, i.e. s3.
In the quadravalence section, that judges in phase III s3 motor 12 stops whether to produce pulse voltage, if produced pulse voltage really in the phase III, just enter next step, otherwise will turn back to second stage s2, for the perception of laundry amounts will be restarted motor, i.e. s4.
If the judged result of quadravalence section s4 is definite, in five-stage, the surplus electricity that is judged as motor 12 has been produced pulse voltage, and the time that first pulse voltage is produced is input to data processing division 15, i.e. s5.
In the 6th stage, monitor whether the pulse voltage of five-stage s5 becomes 0v, and be the time that recording impulse voltage exists.Be s6.
If in the 6th stage s6, when pulse voltage is not 0v, just gets back to and continue among the five-stage s5 time that the calculation pulse voltage exists; If in the 6th stage s6, pulse voltage is that 0v entered for the 7th stage.In the 7th stage, just finish the calculation of the pulse voltage time of five-stage s5, and its value is input to 17 li of loggers, calculate the time that pulse voltage is in 0v simultaneously.
In the 8th stage, pulse voltage among the 7th stage s7 is in the no pulse voltage reference value that has configured in the time of 0v and phase I to be compared, if the time ratio no pulse voltage reference value of no pulse voltage is little, just get back to the time of calculating other pulse voltage in the quadravalence section again.
If the time ratio no pulse voltage reference value of no pulse voltage is big, then be judged as surplus electricity and finish, entered for the 9th stage.In the 9th stage, the pulse voltage time on the logger 17 of calculating, record in the 7th stage s7 is performed calculations and export.Be s9.
In ten stages, the time total value of the pulse voltage of exporting in the 9th stage and the laundry amounts perception a reference value that configured in the phase I are compared the laundry amounts of determining to enter sink inside, and determine the amount of the washings that will enter.
When the middle water level of the laundry amounts perception a reference value that the time ratio that this time, determined pulse voltage existed configures is big, just illustrate that laundry amounts is fewer; If the middle water level of the laundry amounts perception a reference value that the time ratio that opposite pulse voltage exists configures is little, but bigger than a reference value of high water level the time, just illustrate that laundry amounts is heavier; If when the high water level of the laundry amounts perception a reference value that the time ratio that pulse voltage exists configures is also little, just illustrate that laundry amounts is very heavy.
