Description
Technical field
The present invention relates to a kind of washing machine, particularly a kind of method and a kind of washing machine that uses this method with the inflow measuring clothes weight.
Background technology
In being equipped with the automatic washing machine of computer controller, one side is for using water wisely and on the other hand in order to reach the clean result of expectation, washing machine is equipped with the device that can measure laundry item weight usually.Control the water consumption in the washing process on the one hand and control wash time on the other hand by computer according to the clothes weight of measuring.The water consumption of described washing process comprise embathe, the water consumption of washing and each program of rinsing.In existing automatic washing machine, the measurement one side of clothes weight is determined clothes weight (pulse number measurement) by the pulse number of the self induction electromotive force of the drive motors of use inner tank of washing machine, determines clothes weight (revolution speed measuring) with the revolution after the drive motors outage of inner core on the other hand.Because these two kinds of methods have bigger error, so proposed a kind of computer automatic washing machine again, described washing machine utilizes weight sensing device to carry out the measurement of clothes weight.The structure of above-mentioned washing machine is shown in Fig. 1 and 2.
A full-automatic impeller type washing machine shown in Figure 1, this washing machine is equipped with Weight-measuring device.In casing 11, (be also referred to as and be housing) urceolus 12 is set.An inner core 13 and an impeller 14 are set in urceolus 12 (being outer container), and they are connected with a transmission system 15.Four suspension rods 16 remain on urceolus 12 in the casing 11.Above-mentioned Weight-measuring device---weight sensing device 17---is arranged on junction or the junction that is arranged on suspension rod 16 and urceolus 12 like that shown in the image pattern 1 for example between suspension rod 16 and the casing 11.Also possible is that this weight sensing device is arranged on the leg of casing 11.
