Problems solved by technology

[0003] However, the signal processing process of the washing machine often has a time delay, and the communication between the main control board of the washing machine and its motor also takes time, so if the vibration displacement calculated by the acceleration signal reaches 3mm and then the washing machine is stopped, the outer tub of the washing machine will actually The displacement has exceeded 3mm, that is, there is a danger of hitting the barrel
[0004] Therefore, a new vibration displacement detection scheme for washing machines is needed to avoid barrel collisions due to signal processing delays

Embodiment 1

[0036] Combine below figure 1 and figure 2The dehydration control method of the embodiment of the present invention will be described in detail.

[0037] Such as figure 1 As shown, the dehydration control method according to the embodiment of the present invention specifically includes the following process steps:

[0038] Step S102, when the washing machine executes the dehydration program, acquire the vibration velocity and vibration acceleration of the outer tub of the washing machine in the vibration direction at the current moment.

[0039] Wherein, the vibration direction includes an X-axis direction, a Y-axis direction and a Z-axis direction in a spatial Cartesian coordinate system.

[0040] That is to say, it can be predicted that the outer tub of the washing machine can predict the vibration displacement in one or more vibration directions in the X-axis direction, the Y-axis direction and the Z-axis direction of the spatial rectangular coordinate system, so as to ...

Embodiment 2

[0060] Such as image 3 As shown, the dehydration control device 30 according to the embodiment of the present invention includes: an acquisition module 302 , a determination module 304 and a processing module 306 .

[0061] Wherein, the obtaining module 302 is used to obtain the vibration speed and vibration acceleration of the outer tub of the washing machine in the vibration direction at the current moment when the washing machine executes the dehydration program; The vibration acceleration determines the vibration displacement of the outer tub in the vibration direction after the preset time exceeds the current moment; the processing module 306 is used to determine whether the washing machine hits the tub according to the vibration displacement .

[0062] In this embodiment, during the process of executing the dehydration program, the washing machine calculates in real time the current vibration velocity and vibration acceleration of the outer tub of the washing machine i...

Embodiment 3

[0076] Such as Figure 4 As shown, the dehydration control device according to the second embodiment of the present invention includes:

[0077] A processor 404; a memory 402 for storing executable instructions of the processor, wherein the processor 404 is used for implementing the corresponding dehydration in the first embodiment above when executing the executable instructions stored in the memory 402 The steps of the control method.

Abstract

The invention provides a dehydration control method and device, a computer readable storage medium and a washing machine. The dehydration control method comprises the following steps of when the washing machine executes a dehydration program, acquiring the vibration speed and the vibration acceleration of an outer barrel of the washing machine in the vibration direction at the current moment; according to the vibration speed and the vibration acceleration, determining the vibration displacement amount of the outer barrel in the vibration direction after the current moment is exceeded by the preset time; and determining whether barrel collision of the washing machine occurs or not according to the vibration displacement amount. According to the technical scheme, the accuracy and timelinessof a judgment result of judging whether the barrel collision event of the washing machine occurs or not can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of washing machines, in particular to a dehydration control method, a dehydration control device, a computer-readable storage medium and a washing machine. Background technique [0002] At present, when the washing machine performs the dehydration program, the MEMS (Micro-Electro-Mechanical System, micro-electromechanical system) sensor is used to detect the acceleration signal of the outer tub of the washing machine in the vibration direction, and convert it into the displacement signal of the outer tub through two integral operations , so as to perform vibration detection and water replenishment control of the washing machine according to the displacement signal. However, considering that the gap between the outer tub of the washing machine and its cabinet is very small, in order to prevent the outer tub from colliding with the cabinet during high-speed dehydration, it is necessary to add a shutdow...
