Problems solved by technology

[0012] However, the existing sensing devices and methods have the following disadvantages; when the laundry increases, the clothes may be entangled together, which will cause no or irregular pulse voltage when the power supply is stopped The situation of the data, so the analysis effect of the pulse voltage data will be reduced, and the reliability is not high

Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings.

[0029] Fig. 3 is a diagram of the sensing device for the amount of laundry in the washing machine in the present invention. The sensing device has the following parts: the motor 12, the amount of clothing consisting of a capacitor 13 between the main coil and the secondary coil of the motor 12 and an electrical measuring device 16 that converts the signal into pulse voltage data as the voltage changes on the capacitor The sensing part is a control part composed of a data processing part 15 and a recorder 17 which has set sensing reference data of the amount of clothes and recording pulse voltage data time. The motor 12 is a device for rotating the pulsator of the washing machine, and a pulse current caused by residual electricity is generated in the motor, and the amount of clothes can be sensed through this pulse current. The laundry amount sensing unit plays a role ...

Abstract

The present invention is the clothing amount sensing method for the washing machine to obtain the clothing amount accurately so as to adding water in the proper amount for raised washing effect. The clothing amount sensing method includes the following steps: presetting the reference data for judging clothing amount and the reference voltage after last pulse voltage; calculating the pulse voltage data from power off of the motor to the last pulse produced by the after voltage of the motor; and comparing the obtained pulse voltage data with set reference data to judge the clothing amount range and load.

Description

technical field [0001] The invention relates to a working method of a washing machine, more specifically, to a method for judging the laundry load of the washing machine. Background technique [0002] Generally speaking, the washing objects in the washing machine will naturally wash off the dust with the chemical action of the detergent, but it is difficult to wash the clothes with detergent alone, and the friction and vibration of the washing machine can also be used to promote dust removal. of detachment. [0003] The operation control method of the above-mentioned existing washing machine is as follows: first, sense the amount of clothes put into the washing tank, and set the water intake, detergent and washing time according to the amount of clothes. Then the motor drives the pulsator to rotate, and the water in the washing tank will rub against the clothes to complete the washing task by the rotation of the pulsator. [0004] When the washing task is completed, the se...
