A washing machine is a cleaning appliance for washing laundry using mechanical energy generated by electric energy. Washing machines are generally classified into drum washing machines and pulsator washing machines according to a washing principle. Pulsator washing machines generally include a cabinet and a tub disposed in the cabinet. The bottom of the washing tub is provided with a pulsator, and the pulsator is generally provided with protruding ribs. When washing clothes, the motor drives the pulsator to rotate, and the water flow in the washing barrel forms vortex which is timely right-handed and timely left-handed under the driving of the pulsator, so that clothes are driven to rotate and roll, and the washing effect of the clothes is realized.
When the pulsator washing machine is used for dewatering, uneven distribution of clothes in the drum can lead to eccentricity of the washing drum, the washing drum collides with the box body, noise is large, even the box body is shifted, the dewatering effect of the clothes is affected, and the experience effect of a user is poor. In order to avoid the above problems, the conventional pulsator washing machine is generally provided with a control lever above a tub, and when a dehydration process is started, if the eccentricity in the tub is too large, the tub will swing to a large extent, and the tub will touch the control lever located above. The control rod sends a signal to the control component, and the control component judges that the eccentricity in the washing tub is overlarge at the moment according to the signal sent by the control rod, so that the balance correction time sequence is entered.
However, the existing process of judging whether the pulsator washing machine is eccentric is that after the dehydration procedure is started, if the washing tub is eccentric, the washing tub still swings greatly at the beginning stage of the dehydration procedure, and the washing tub still collides with the box body, so that the problems of overlarge noise or box body displacement and the like occur; and the washing machine is easily damaged by the collision of the washing tub and the box body.

Detailed Description
In order to make the technical problems solved, the technical scheme adopted and the technical effects achieved by the invention more clear, the technical scheme of the invention is further described below by a specific embodiment in combination with the attached drawings.
As shown in fig. 1, the present embodiment provides a method for judging eccentricity of a washing machine, which is based on laundry weighing and is performed before a dehydration process is started. Specifically, the weight of the dry laundry in the tub is measured after the user puts the laundry into the tub and before the washing course starts. And obtaining the critical weight of the wet clothes corresponding to the measured weight of the dry clothes, wherein the critical weight is the weight of the wet clothes corresponding to the maximum allowable eccentric amount when the washing machine works normally, and the critical weight can be a program preset weight value. After the water draining process is finished and before the dewatering process is started, measuring the weight of wet clothes in the washing tub, and comparing the weight of the wet clothes with the critical weight, if the weight of the wet clothes is larger than the critical weight, judging that the washing machine is in a load eccentric state.
In this embodiment, the weight of the dry laundry and the weight of the wet laundry may be measured by a fuzzy weighing method. The fuzzy weighing method is a common weighing method of the existing pulsator washing machine, and the fuzzy weighing method is a method for enabling a motor to rotate positively and negatively according to a certain rotation stop ratio and acquiring the weight of clothes according to the change condition of a current value provided by a driving plate to the motor, and is not limited in the embodiment, so long as the fuzzy weighing method in the prior art is suitable for the judging method of the eccentricity of the washing machine in the embodiment. When the dried laundry is put in, the weight of the dried laundry may be obtained by fuzzy weighing. After the water discharge is finished and before the dewatering process is started, if the problem of load eccentricity does not exist in the washing tub, the motor rotates to drive the pulsator to rotate, and clothes at the moment only rub with the pulsator under the action of gravity, so that the current value provided by the driving plate for the motor is smaller, and the value obtained by fuzzy weighing is lower. When the problem of eccentric load exists in the washing tub, the clothes are more contacted with the inner wall of the washing tub, friction is generated between the clothes and the inner wall of the washing tub, and certain resistance exists on the rotating clothes by the inner wall, so that the current value provided for the motor by the driving plate is larger, and the value obtained by fuzzy weighing is higher. When the weight of wet clothes obtained through fuzzy weighing measurement is larger than the critical weight set by a program, the fact that the friction value between the clothes and the inner wall of the washing tub is larger is shown, the fact that the washing machine is in a load eccentric state is judged, and balance adjustment is needed to be conducted on the clothes in the washing tub is conducted, so that the phenomenon that the washing tub swings greatly due to overlarge eccentricity in a dehydration process is avoided, collision between the washing tub and the box body is avoided, noise is reduced, and use experience of a user is improved.
The method for determining eccentricity of the washing machine in this embodiment preferably determines eccentricity when the load of the washing machine is small. When the load of the washing machine is small and the eccentricity problem does not exist, clothes are basically stacked on the pulsator and are not contacted with the inner wall of the washing tub, when the eccentricity occurs, the clothes are contacted with the inner wall of the washing tub, and the friction between the clothes and the inner wall of the washing machine increases the resistance in the rotating process, so that whether the washing machine is eccentric or not can be judged according to the measured weight of wet clothes. When the load of the washing machine is large, the laundry stack is inevitably in contact with the inner wall of the tub, friction exists between the laundry and the inner wall of the tub under the eccentric and non-eccentric conditions, and whether the washing machine is eccentric or not cannot be accurately judged by comparing the critical weight and measuring the weight of wet laundry.
Of course, in other embodiments, the weight of dry and wet laundry may be measured by other means.
When the critical weight of wet clothes corresponding to the dry clothes is obtained, the weight of the dry clothes can be divided into a plurality of weight intervals, and each weight interval is correspondingly preset with the critical weight of one wet clothes, so that the critical weight can be conveniently obtained. In order to obtain the corresponding critical weight of the weight value of the dried clothes, a plurality of weight intervals can be continuously arranged. Specifically, in two adjacent weight intervals, the minimum value of one weight interval is equal to the maximum value of the other weight interval, so that any weight value of the dried clothes can be ensured to be corresponding to a critical value.
To improve the accuracy of the critical weight selection, the interval between the maximum and minimum values of each weight interval should not be too large. The denser the weight interval distribution, the more accurate the obtained critical weight value, and the more accurate the final eccentric judgment result. Specifically, the interval between the maximum value and the minimum value of the weight interval may be 0.5kg to 1.0kg, for example, may be 0.5kg, 0.6kg, 0.7kg, 0.8kg, 0.9kg, 1.0kg, etc., and specific values may be determined according to actual situations or selected according to the needs of users.
To improve the accuracy of the eccentricity judgment of the washing machine, the accuracy of the critical weight selection can be improved.
In the aspect of improving the accuracy of selecting the critical weight, the method can be realized by dividing more weight intervals, and can also select proper critical weight according to the type of clothing materials. Because the water absorbability and hardness differences of the clothes with different materials are large, in order to improve the accuracy of the eccentric judgment of the washing machine, a database of the critical weight of wet clothes corresponding to the weight of the dried clothes with different materials can be established according to the different materials of the clothes. Before washing, a user selects a corresponding clothes type, and according to the measured weight of the dried clothes and the type of clothes materials, the critical weight of the corresponding wet clothes is obtained in a corresponding database, so that the accuracy of the comparison result of the critical weight and the weight of the wet clothes is improved. Specifically, databases corresponding to chiffon, down, jean, cotton cloth and other materials can be created, and critical weights of wet clothes corresponding to the dry weights of the corresponding materials are prestored in each database, so that the accuracy of eccentric judgment is further improved.
The embodiment also provides a pulsator washing machine, which adopts the method for judging the eccentricity of the washing machine, and enters a balance correction time sequence after judging that the washing machine is in a load eccentric state. By adopting the judging method, the phenomenon that the washing tub swings greatly due to overlarge eccentricity in the dewatering process can be avoided, the collision between the washing tub and the box body is avoided, noise is reduced, and the use experience of a user is improved.
The foregoing is merely exemplary of the present invention, and those skilled in the art should not be considered as limiting the invention, since modifications may be made in the specific embodiments and application scope of the invention in light of the teachings of the present invention.
