AI Technical Summary

Problems solved by technology

During the high-speed drying process, the load is easily attached to the inner cylinder wall of the washer-dryer due to the centrifugal force, resulting in the load being unable to be dried evenly during the subsequent drying process, and at the same time causing a burden to the motor
[0004] The prior art all-in-one washing and drying machine requires the user to check whether the load is attached to the wall of the inner cylinder before performing the drying program, and manually removes the load, shakes it loose again, and puts it into the inner cylinder to improve the drying efficiency. effect, poor user experience

Embodiment 1

[0031] A control method for an all-in-one washing and drying machine. When the high-speed dehydration is completed and the drying program is about to enter, the motor runs at a low speed, detects multiple current values ​​and eccentric values ​​at different speeds, and compares the obtained current values ​​and eccentric values ​​to determine the load. Whether it is attached to the wall, if the load is not attached to the wall, enter the drying program, if not, execute the load stripping program and enter the drying program.

[0032] The speed of the motor is controlled to increase or decrease, and the current value and eccentric value of multiple different speeds are detected during the process of increasing or decreasing the speed.

[0033] The rotational speed of the motor at low speed is V, 5r / min≤V≤300r / min, preferably 10r / min≤V≤260r / min, more preferably 20r / min≤V≤150r / min.

[0034] First compare the current values ​​at different speeds to determine whether the load is at...

Embodiment 2

[0046] A control method for an all-in-one washing and drying machine. When the high-speed dehydration is completed and the drying program is about to enter, the current values ​​and eccentric values ​​corresponding to the multiple speeds of the motor when the motor is running at low speed are detected and compared to determine whether the load is attached to the wall. If the load If it is not attached to the wall, enter the drying procedure, if not, execute the load stripping procedure and enter the drying procedure.

[0047] When the motor is running at a low speed, the multiple rotational speeds increase or decrease gradually according to the magnitude of the rotational speed.

[0048] The rotational speed of the motor at low speed is V, 5r / min≤V≤300r / min, preferably 10r / min≤V≤260r / min, more preferably 20r / min≤V≤150r / min.

[0049] In this embodiment, three speed points are selected in the low-speed running state of the motor, and the three speeds are increased according to t...

Embodiment 3

[0061] The difference between this embodiment and the second embodiment is that the speeds selected for measurement are not limited to three when running at a low speed. In this embodiment, four speeds can be selected to be measured.

[0062] A control method for an all-in-one washing and drying machine. When the high-speed dehydration is completed and the drying program is about to enter, the current values ​​and eccentric values ​​corresponding to the multiple speeds of the motor when the motor is running at low speed are detected and compared to determine whether the load is attached to the wall. If the load If it is not attached to the wall, enter the drying procedure, if not, execute the load stripping procedure and enter the drying procedure.

[0063] The rotational speed of the motor at low speed is V, 5r / min≤V≤300r / min, preferably 10r / min≤V≤260r / min, more preferably 20r / min≤V≤150r / min.

[0064] In this embodiment, three speed points are selected in the low-speed runni...

Abstract

The invention belongs to the technical field of clothes processing devices, and relates to a control method of an integrated washing and drying machine and the integrated washing and drying machine. In the control method of the integrated washer-dryer, after the high-speed dehydration of the integrated washer-dryer is completed and the drying program is about to start, the motor runs at a low speed to detect a plurality of current values ​​and eccentricity values ​​at different rotation speeds, and compare the obtained current values ​​and Eccentric value to determine whether the load is attached to the wall, if the load is not attached to the wall, enter the drying program, if not, execute the load stripping program, and enter the drying program. The control method prevents the load from sticking to the wall of the inner cylinder, makes the load dry evenly, shortens the drying time, has high drying efficiency, and does not require human intervention, making it more intelligent and humanized.

Description

technical field [0001] The invention belongs to the technical field of clothes processing devices, and in particular relates to a control method of an integrated washing and drying machine and the integrated washing and drying machine. Background technique [0002] With the continuous development of social science and technology and the continuous improvement of living standards, people have higher and higher requirements for clothes processing devices. As far as washing machines are concerned, in addition to the basic laundry functions, they also hope that they can also have drying functions. , to meet the special needs of instant washing and wearing, therefore, the washing machine with integrated washing and drying function is more and more favored by consumers. [0003] In the drying process, the lower the moisture content of the load, the better, so it is necessary to control the drying speed of the washer-dryer to a higher speed, and the higher the speed, the better. D...
