Problems solved by technology

In this driving mode, according to the structural characteristics of the washing machine, the detection of the amount of clothes cannot be accurately realized through the existing method of detecting the amount of clothes
[0006] This shows that the above-mentioned existing washing machine still has many defects to the method for detecting the amount of clothes, and it needs to be improved.

no. 1 Embodiment —

[0039] The first embodiment of the present invention is such as figure 2 As shown, firstly, the main microcomputer 21 will judge S21 whether there is a washing instruction input.

[0040] If the above judgment result S21 is that there is a washing instruction input, then the agitator is accelerated, and the timing S22 is started.

[0041] Here, the main microcomputer 21 instructs the microcomputer 17 to accelerate the stirrer, and if the rotation of the stirrer is detected based on the output of the speed sensor 15, time is started. In addition, the microcomputer 17 controls the drive part 13 according to the instruction|indication of the said main microcomputer 21, and accelerates a stirrer.

[0042] Next, whether the rotation speed of the agitator has reached the set speed (for example, 150rpm) is judged S23, if it has reached the set speed, then the power is cut off, and the amount of clothes is detected by the time so far obtained by counting S24 .

[0043] Here, it is...

no. 2 Embodiment —

[0046] The second embodiment of the present invention is such as image 3 As shown, first, the main microcomputer 21 judges whether there is a washing instruction input S31.

[0047] Here, the washing instruction is input by the user through the user interface 18 .

[0048] If the above judgment result S31 is that there is a washing instruction input, then the agitator is accelerated S32, and whether the agitator has reached the set speed (eg 150 rpm) is judged S33.

[0049] Next, if the set speed is reached, the power is cut off to cause the agitator to rotate by inertia, and the number of pulses generated with the inertia rotation, that is, the output of the speed sensor 15, is counted S34.

[0050] Here, the main microcomputer 21 issues the agitator acceleration command to the microcomputer 17, and if it is judged that the rotational speed of the agitator has reached the set speed according to the output of the speed sensor 15, then the power is cut off, and then the outpu...

no. 3 Embodiment —

[0055] The third embodiment of the present invention is a method of combining the above-mentioned first embodiment and the second embodiment. The clothes quantity detection method in the above-mentioned first embodiment is more reliable when there is a large amount of clothes. The second embodiment The laundry amount detection method is more reliable when the amount of laundry is small.

Abstract

The invention relates to a clothes amount detecting method for a washing machine, which can detect the clothes amount accurately in the washing machine of directly reversed motor driving mode. The method includes the following steps: accelerating the mixer when a washing instruction is inputted; timing when the rotation speed reaches the setting speed; comparing the timing result with the clothes amount table which is set by time to detect the clothes amount. The invention can execute the most proper clothes amount detection according to the washing machine characteristics.

Description

technical field [0001] The invention relates to a detection method of a washing machine, more specifically, an invention related to a detection method of the laundry amount of the washing machine. Background technique [0002] Generally speaking, the washing machine removes all kinds of pollution attached to clothes, bedding, etc. It can automatically set the washing method by sensing the amount and type of washing through sensors, and inject washing water to an appropriate water level according to the amount and type of washing, and then execute the washing process under the control of the microcomputer . [0003] In addition, the driving methods of the existing fully automatic washing machines are as follows, that is, through the belt (belt) and pulley (pulley) for power transmission, the rotational power of the driving motor is transmitted to the washing shaft or the dehydration shaft, so that the agitator Or the way that the dehydration bucket rotates; through the spee...
