Washing machine

Abstract

The invention discloses a washing machine. The washing machine comprises a casing, a cleaning tank and an ultrasonic generation device. A washing barrel is arranged in the casing; the cleaning tank isformed in the casing; the ultrasonic generation device is arranged above the cleaning tank and connected with the casing, and an ultrasonic vibration end of the ultrasonic generation device faces thecleaning tank; after to-be-washed laundry is placed between the ultrasonic generation device and the cleaning tank, the ultrasonic vibration end of the ultrasonic generation device is in partial contact with the to-be-washed laundry, and ultrasonic vibration waves are directly conducted to the to-be-washed laundry soaked in washing liquid for cleaning. The washing machine can not only clean the whole laundry but also quickly and thoroughly remove local stubborn stains on the laundry. The ultrasonic vibration end of the ultrasonic generation device is in direct contact with the soaked to-be-washed laundry so that not only can the consumption of the ultrasonic waves by the soft laundry be greatly reduced, the ultrasonic effect is enhanced, but also resonance of the deeper stains of the laundry can be caused, and the purpose of thoroughly removing the stains is achieved.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a washing machine. Background technique [0002] The cleaning power of the washing machine on the clothes is generally relatively average, and the cleaning power on the heavy stains on the clothes is weak when the washing is not heated. Also can't be aimed at the partial cleaning of clothing, it is difficult to remove the partial heavy stain on clothing. Studies have shown that the longer the stain is attached to the clothes, the easier the stain will penetrate into the fabric fibers, and it will be difficult to wash off after a long time. After the clothes are stained, the ideal way is to wash the stains off in time. Users generally wash or pretreat fabrics by hand or with a brush and a special detergent. No matter which method is used, the hands will come into contact with the detergent, which will cause damage to the hands of the detergent, and the cleaning effect...

AI Technical Summary

Problems solved by technology

[0004] However, unlike the stains on the surface of rigid objects that are easy to shake off, clothes are generally made of various fibers, which are soft in texture and have the effect of absorbing ultrasonic waves. When ultrasonic washing devices wash clothes, the loss of ultrasonic waves is large; The washing device generally uses the high-frequency ultrasonic cleaning equipment emitted by the ultrasonic transducer to vibrate the liquid in the cleaning tank to generate many tiny high-frequency bubbles. These small bubbles continuously hit the surface of the clothes to be cleaned, and the stains on the surface of the clothes to be cleaned , oil stains, etc. resonate to make stains and oil stains fall off

For fabrics such as clothing, the stains of cotton products are adsorbed inside, or have penetrated into their molecules or atomic tissues. High-frequency air bubbles can only resonate on the surface of the clothes. Clothes placed directly in the washing tank have limited cleaning effect, and the effect on local stubborn stains is even less ideal
