Washing machine with self-protection device

Abstract

The invention discloses a washing machine with a self-protection device. The washing machine comprises a wash bucket, a drive mechanism and a control device, wherein the bottom of the wash bucket is provided with a rotary device, a rotary shaft of the rotary device is provided with a pressure sensor, the rotary shaft is hollow, the top of the rotary shaft is provided with a bearing, the pressure sensor is placed in the bearing and is fixed, and the sensing face of the pressure sensor is arranged at the top end of the rotary shaft; the drive mechanism is arranged below the rotary device and drives the rotary device to rotate; the control device is arranged on an upper cover of the washing machine and is electrically connected with the pressure sensor and the drive mechanism; the control device comprises a soft starter and a central processor, the soft starter controls soft start and soft stop of the drive mechanism, and the central processor is communicated with the soft starter, receives electric signals of the pressure sensor and controls drive power of the drive mechanism. The washing machine saves energy and eliminates vibration caused when the washing machine is started or shut off, noise is lowered, and the service life of the washing machine is prolonged.

Description

Technical field [0001] The invention relates to a washing machine with a self-protection device. Background technique [0002] There are many types of washing machines nowadays. When the plasma washing machine is working, the plasma in the drum gently washes the surface of the object to be cleaned. The rotating device at the bottom of the drum shakes the laundry to make the plasma fully contact the laundry. The time of cleaning can completely clean the organic pollutants, and the cleaning degree reaches the molecular level. The washing machine uses tap water as the cleaning medium and uses washing powder or liquid detergent for effective washing. However, whether it is a plasma washing machine or a washing machine , The amount of laundry to be washed in the washing machine is random, and the driving force of the rotating device at the bottom of the washing machine is constant. This will cause a waste of energy when there are fewer laundry to be washed, and the rotating device is ...

Problems solved by technology

[0002] There are many types of washing machines today. When the plasma washing machine is working, the plasma in the washing tub gently scours the surface of the object to be cleaned. The cleaning of time can make the organic pollutants be thoroughly cleaned, and the cleaning degree reaches the molecular level. The washing machine uses tap water as the cleaning medium, and uses washing powder or laundry liquid for effective cleaning. However, whether it is a plasma washing machine or a washing machine , the amount of clothes to be cleaned in the washing machine is random, and the driving force of the rotating device at the bottom of the washing machine is constant, which will cause a waste of energy when there are fewer clothes to be cleaned. When it is stopped, it will cause certain vibrations to the washing machine, make a lot of noise, and reduce the life of the washing machine
