Description

Control method of washing machine
Technical Field
The invention relates to the field of washing machines, in particular to a control method of a washing machine.
Background
In the process of dehydration, the washing machine detects the balance of a washing barrel, when the washing machine is unbalanced, the washing machine is controlled to execute some balance operations, such as controlling the washing barrel to slow down or stop rotating or controlling the washing barrel to feed water or alarming and waiting for users to solve, the washing machine mainly has two structures in the aspect of detecting the balance of the washing barrel, one structure is that a barrel collision switch is arranged on the washing machine, the balance of the washing barrel in the dehydration process is judged through the barrel collision switch, and the other structure is that a control rod is arranged in the washing machine and used for safety monitoring in the dehydration process of the washing machine. When the eccentricity of the washing machine is too large, the outer barrel assembly of the washing machine can strike the control rod, so that the connection condition of the detection circuit is changed, and the unbalanced state of the washing barrel is obtained.
However, in time working, the structures such as the barrel-bumping switch and the control lever are too sensitive or too slow, and the detection result is affected, for example, the abrasion deformation of the mechanical part of the barrel-bumping switch can greatly reduce the detection reliability.
In the control method of the existing washing machine, the detection logic of the low speed and the high speed of the washing barrel is the same, so that the eccentricity detection is inaccurate, the high speed operation state and the low speed operation state of the washing machine adopt the same detection control logic and are not in accordance with the actual situation, different rotating speed intervals are treated differently, the aims of accurately detecting the unbalance of the washing barrel and effectively rectifying the deviation of the washing barrel can be fulfilled, and the safe execution of the dehydration program of the washing machine is ensured.
The present invention has been made in view of this.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a control method of a washing machine, which fully considers the rotating speed of a washing barrel, selects corresponding judging and stopping logic according to the rotating speed of the washing barrel, improves the unbalance detection accuracy of the washing barrel, and therefore, performs effective balance correction control in the dehydration process.
In order to solve the technical problems, the basic conception of the technical scheme adopted by the invention is as follows:
the washing machine adopts corresponding judging logic to control the current dewatering process according to the rotating speed, wherein the judging logic is used for detecting whether the actual barrel collision times reach the collision times or not and/or detecting whether the actual barrel collision times reach the collision times or not according to the barrel collision detection frequency when detecting that the washing barrel is in a certain rotating speed dewatering stage.
The existing washing machine is provided with a control rod for safety monitoring in the dewatering process of the washing machine. When the eccentricity of the washing machine is too large, the outer barrel assembly (or the washing barrel) of the washing machine can strike the control rod, so that the connection condition of the detection circuit is changed. However, in the prior art, the low-speed judgment logic and the high-speed judgment logic are always the same, which can lead to inaccurate detection and poor control effect.
In the scheme, the rotating speed of the washing barrel is fully considered, corresponding judging and stopping logic is selected according to the rotating speed of the washing barrel, and the unbalanced detection accuracy of the washing barrel is improved, so that effective balance correction control is carried out in the dehydration process.
Preferably, in the dehydration process of the washing machine, fixed barrel collision detection frequency is adopted in different rotation speed dehydration stages, the number of times of collision and stop of corresponding judgment and stop logic in different rotation speed dehydration stages is different, and when the washing machine is in a certain rotation speed dehydration stage, the current dehydration process is controlled by adopting the corresponding judgment and stop logic;
preferably, in the dehydration process, the stage with higher rotation speed corresponds to more times of collision stopping of the judging and stopping logic.
In the scheme, different judging and stopping logics are adopted aiming at different rotational speed dehydration stages, so that unbalance detection accuracy is improved, effective balance correction control is facilitated, the greater the rotational speed of the washing barrel is, the greater the number of times of collision and stopping of the corresponding judging and stopping logics is, and unbalance of the washing barrel is accurately reflected.
Preferably, the dehydration process has a first rotational speed dehydration stage and a second rotational speed dehydration stage, wherein the number of times of collision of the first rotational speed dehydration stage corresponding to the judgment logic is T1, and the number of times of collision of the second rotational speed dehydration stage corresponding to the judgment logic is T2:

and when the washing machine is in the second rotating speed dehydration stage, detecting whether the actual barrel collision times reach the collision stop times T2 or not at the fixed barrel collision detection frequency.
Of course, in the dehydration process, the control of a plurality of rotational speed dehydration stages can be performed according to the actual situation, not only the two rotational speed dehydration stages.

or the washing machine detects the actual barrel collision times in the set time length and judges whether the actual barrel collision times in the set time length reach the corresponding collision stop times of the rotating speed.
The scheme provides two different control modes of judging and stopping logic, wherein the first mode is to detect the actual continuous collision times of the washing barrel, and when the continuous collision times of the washing barrel reach the corresponding collision and stopping times, the washing machine is judged to need to execute balance correction operation; and the second is to detect the actual number of times of barrel collision in the set time, and when the actual number of times of barrel collision in the set time reaches the corresponding number of times of collision stop, the washing machine is judged to need to execute balance correction operation.
Preferably, the washing machine is in the process of the first rotational speed dehydration stage/the second rotational speed dehydration stage, and circularly detects whether the actual continuous barrel collision times of the washing barrel/the actual barrel collision times in the set time length reach the corresponding collision stop times of the rotational speed.

Preferably, in the dehydration process, the stage with higher rotation speed corresponds to the greater collision detection frequency of the judging and stopping logic.
In the scheme, the higher the rotating speed of the washing barrel is, the higher the barrel collision detection frequency of the washing machine is, so that the washing machine has an accurate unbalance detection effect on all washing machines when the washing barrels are at different rotating speeds, and unbalance correction control of the washing machine is improved.

and when the washing machine is in the second rotating speed dehydration stage, detecting whether the actual barrel collision times reach the fixed collision stop times or not according to the barrel collision detection frequency F2.
Preferably, different washing machines adopt corresponding judging and stopping logic to control the current dehydration process according to different diameters of washing barrels of the washing machines;
preferably, at the same rotation speed, the larger the diameter of the washing tub of the washing machine is, the higher the tub collision detection frequency and/or the larger the collision stop number are/is by adopting the corresponding judgment stop logic.
