Problems solved by technology

[0003] After a certain period of use, the belt of the transmission will slip or break due to aging, so the roller cannot be driven
At this time, if the clothes processing device cannot judge this abnormal situation in time, but keeps other parts working according to the selected program, it will cause waste of energy and even damage the clothes
What's more serious is that if the clothes processing device executes the drying process when the belt loses its function, the temperature distribution in the drum will be uneven due to the static drum, which will cause the clothes to be damaged by high temperature, and may even damage the rubber parts or the inside of the machine. Plastic parts are baked

Embodiment Construction

[0017] A clothes processing device, which can be a washing machine, a clothes dryer or an integrated washing and drying machine, is provided with a drum for accommodating clothes, and a motor is connected with the drum through a belt transmission device to drive the drum to rotate. The motor is electrically connected to a power conditioning module and a power source. A control device controls the electrical components provided in the laundry treatment device according to program settings. The control unit includes a programmable controller with a microprocessor and memory. During the running of the laundry treatment program, the control device can adjust the output speed of the motor according to the program setting.

[0018] The power conditioning module contains a thyristor. The conduction angle of the thyristor determines the output power of the motor. The larger the conduction angle, the greater the output power of the motor; conversely, the smaller the conduction angle...

Abstract

The invention relates to an abnormity judgment method of a clothes treatment device. The clothes treatment device comprises a control device, a drum and a motor, wherein a belt transmission device is connected between the drum and the motor. The method comprises the steps of: detecting the conduction angle theta d of the voltage applied to the motor in the operating process of the clothes treatment device and judging whether the belt transmission device is abnormal by the control device according to the detected conduction angle theta d. The method is adopted by the clothes treatment device. Once the belt transmission device works abnormally, particularly loses the transmission function, the control device judges the abnormity in time and takes corresponding safe and alarming measures, thus the risk caused by the continuous working of the clothes treatment device when the belt transmission device works abnormally is avoided.

Description

【Technical field】 [0001] The invention relates to a method for judging whether a belt connected to a motor has lost its function due to falling off or breaking, and also relates to a clothes processing device using the method. 【Background technique】 [0002] Clothes processing devices such as washing machines, clothes dryers, or all-in-one washing and drying machines are usually equipped with a drum to accommodate clothes and a motor to provide driving force. A belt drive is connected between the motor and the drum to transmit the rotational motion of the motor to the drum. The corresponding rotation movement. [0003] After a certain period of use, the belt of the transmission will slip or break due to aging, so the drum cannot be driven. At this time, if the clothes processing device cannot judge this abnormal situation in time, but keeps other parts working according to the selected program, energy will be wasted and even clothes will be damaged. What's more serious is ...
