- a washing machine which is provided by the above-mentioned embodiment and in which the weight of garments is measured by means of a filling water amount includes, as shown in Figure 4: a box body 1, respectively provided within the box body 1 inner container 3 and outer container 2, a driving device 4, brackets 5, suspension rods 8, a water supply path 7, a water discharge path 6, and a control device having a central control unit, wherein a water amount sensor device 9 is provided on the water supply path 7 and the water discharge path, respectively.
- the water quantity sensor device is a water meter.
- a detection program for detecting the water absorption rates of various items of clothing and a weight program of the clothes are provided in the central control unit of the control apparatus of the washing machine.
- the aforesaid recognition program for detecting the water absorption rates of various items of clothing is operated by means of a cloth material selection switch on the operation panel, selecting the water absorption rate of the corresponding material material.
- Q- denotes the weight of the garments to be washed
- W_ab- denotes the amount of water absorbed when completely wet the clothes to be washed
- A- denotes the water absorption rate of the garment materials to be washed
- W1 - the filling water volume of the first water supply line up to the intended height; W2- the remaining water discharge after the first water supply called.
