Problems solved by technology

If the clutch is not engaged at all at this time, the clutch will mesh with the fixed ring gear or the DD motor rotor slot due to the vibration of the whole machine during washing or dehydration, which will cause instantaneous toothing, resulting in gear damage or shortened service life, as well as noise; At this time, the clutch is only slightly engaged, and the end of the engaged gear will bear a large force, resulting in gear damage or shortened life.

Embodiment Construction

[0027] Such as figure 1 As shown in the present invention, a washing machine deceleration clutch control method, the steps are as follows:

[0028] Step 1. The main control board receives the washing / dehydration signal, and controls the clutch motor to drive the clutch to move axially;

[0029] Step 2. Check whether the clutch is in place. After the clutch motor runs in place, if the main control board detects the signal that the clutch is in place, control the driving motor to change the speed to the washing / spinning speed. If the main control board does not detect that the clutch is in place signal, the drive motor is controlled to reciprocate forward and reverse within the set speed range, and the clutch is engaged.

[0030] If the timing sequence of forward and reverse reciprocating motion of the driving motor is completed and the engagement in-position signal has not been detected, the clutch motor will run for another cycle, and the above detections will be repeated. I...

Abstract

The invention relates to a washing machine speed reducing clutch control method, a speed reducing clutch and a washing machine. The control method includes that step 1, a mainboard receives a washing or dewatering signal, and a clutch motor is controlled to drive a clutch to move axially; step 2, whether the clutch is meshed in place or not is detected, after the clutch motor runs in place, if a signal indicating that the clutch is meshed in place is detected by the mainboard, a driving motor is controlled to change rotating speed to washing or dewatering rotating speed, and if the signal indicating that the clutch is meshed in place is not detected by the mainboard, the driving motor is controlled to be in forward-backward reciprocating motion within a set rotating speed range to promote meshing of the clutch.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a method for controlling a deceleration clutch of a washing machine, a deceleration clutch and a washing machine. Background technique [0002] The drum washing machines currently on the market realize the washing of the clothes by rotating the inner drum, driving the clothes to a high position and then falling to a low position. When the amount of clothes is put in more, the beating effect of the clothes in the inner drum is not very good. , when fully loaded, there is basically no beating effect. In order to improve the cleaning ratio of the above conditions, a pulsator is added to the rear of the inner cylinder, and the differential operation of the pulsator and the inner cylinder is realized through the function of the reducer, and the rubbing and washing are completed. Improve cleaning ratio. In the dehydration stage, the pulsator and the inner cylinder run at the same speed...
