The filter detection module 6 may be a main control chip, a singlechip or other control modules of the washing machine, and the invention is not particularly limited.
The pressure generated by impurity accumulation and the accumulation degree are in a positive proportion relation, the more the accumulation is, the larger the pressure is, and the detection device for the filter of the washing machine further comprises a prompt module 7, such as a buzzer, a loudspeaker, a touch display screen and the like, when the accumulation degree reaches the maximum value, namely, the detected pressure reaches the set maximum pressure, the prompt module gives a prompt to a user in the form of sound or characters to prompt timely cleaning of the filter, and the technical problem that the filter of the existing washing machine is not cleaned timely is solved.
The brush 3 may be fixed inside the outer tub wall 4 of the washing machine, and when the filter detection is not performed, the brush 3 is not energized, and only when the filter detection instruction is received and the pressure sensor 5 is detected to operate within the set position range, the power supply for the pressure sensor 5 is realized.
In one embodiment of the present invention, the brush 3 is designed to be of a telescopic structure, driven by the brush driving mechanism 8, the brush 3 is retracted to the storage position when the filter detection is not performed, the brush driving mechanism 8 drives the extended storage position to contact with the pressure sensor 5 for power supply when the filter detection is performed, and the brush driving mechanism 8 drives the brush driving mechanism 8 to retract to the storage position after the detection is performed. The brush driving mechanism 8 is connected to the brush 3 and the filter detection module 6, receives a filter detection instruction from the filter detection module 6, and drives the brush 3 to expand and contract.
In the embodiment of the invention, the filter detection device of the washing machine further comprises a sensor 9 for detecting the pressure sensor 5, the sensor 9 is connected with the brush driving mechanism 8 and sends a detection signal to the brush driving mechanism 8, the brush driving mechanism 8 judges whether the filter 1 is detected or not based on the detection signal, and the brush 3 is driven to extend when the filter 1 is detected.
After the sensor 9 detects the pressure sensor 5, on one hand, the brush driving mechanism 8 drives the brush 3 to extend, and on the other hand, in the embodiment of the invention, the inner tub driving mechanism 10 drives the inner tub 2 of the washing machine to stop rotating; the inner tub driving mechanism 10 is connected to the sensor 9 and receives a detection signal, and determines whether the filter 1 is detected based on the detection signal. Further, a positioning lock 11 is installed at the bottom of the inner tub 2 of the washing machine, and when the filter 1 is detected based on the detection signal of the sensor 9, on the one hand, the inner tub driving mechanism 10 drives the inner tub 2 of the washing machine to stop rotating, on the other hand, the positioning lock 11 is controlled to lock the inner tub 2 of the washing machine, so that the relative position of the pressure sensor 5 and the brush 3 is prevented from being deviated due to inertia.
Based on the above proposed detection device for a filter of a washing machine, the present invention also proposes a detection method for a filter of a washing machine, which is executed by a filter detection module 6, as shown in fig. 3, and includes the following steps:
step S31: the inner tub of the washing machine is controlled to rotate at a set rotational speed.
After the washing machine receives the filter detection instruction, the inner barrel driving mechanism 10 drives the inner barrel 2 of the washing machine to slowly rotate at a set rotating speed.
The filter detection command may be a starting signal, a washing program setting signal, a washing program ending signal, etc. of the washing machine, and the step of detecting the filter may be controlled before or after the washing task is executed by the washing machine.
Step S32: when the rotation of the filter to the set position is detected, the control brush supplies power to a pressure sensor in the filter.
The inner tub 2 of the washing machine rotates, the brush 3 detects the filter 1 based on the sensor 9, that is, detects the pressure sensor 5, and when it is judged that the filter 1 or the pressure sensor 5 rotates to a set position based on a detection signal of the sensor 9, the brush 3 is controlled to supply power to the pressure sensor 5, so that the pressure sensor 5 detects the pressure generated by the accumulation of impurities of the filter 1. Alternatively, when it is determined that the filter 1 or the pressure sensor 5 is rotated to the set position based on the detection signal of the sensor 9, the brush 3 is driven by the brush driving mechanism 8 to extend to contact the pressure sensor 5, and power supply to the pressure sensor 5 is realized.
Here, the set position is a position range in which the brush 3 and the pressure sensor 5 can be abutted.
Step S33: and receiving a detection value of the pressure sensor, and judging the accumulation degree of the filter based on the detection value.
After the pressure sensor 5 is powered on, the impurity accumulation pressure of the filter 1 is started and detected, and the detected value is sent to the filter detection module 6, the filter detection module 6 judges the impurity accumulation degree of the filter 1 based on the detected value, and when the accumulation degree reaches the maximum value,
step S34: and sending out prompt information.
The user is prompted to clean the filter in time in a sound or display manner.
In the embodiment of the invention, after the user cleans the filter 1, the prompt information can be emptied in a manual input mode, so that the washing machine knows that the filter 1 is cleaned, whether the user cleans the filter 1 can be judged by continuously detecting the pressure sensor 5 before starting up or after finishing a washing program, the step of detecting the filter can be omitted in a set time after judging that the filter 1 is cleaned, and the filter detection can be started after the set time; specifically, a set period, for example, 3 wash periods, is set according to the wash period, in which the filter detection step is not performed, that is, the filter condition is not detected before the start of the start-up, the start of the wash program, or after the end of the wash program, and the filter detection signal or instruction is sent out after the set period, before the start of the wash program, or after the end of the wash program, the filter detection is performed in the manner of steps S31 to S34, so that the frequency of detection is reduced in a reasonable application range, and the performance of the washing machine is improved.
It should be noted that the above description is not intended to limit the invention, but rather the invention is not limited to the above examples, and that variations, modifications, additions or substitutions within the spirit and scope of the invention will be within the scope of the invention.
