A washing machine with partial pre-washing function

Abstract

The invention discloses a washing machine with a partial pre-washing function. The washing machine includes an ultrasonic cleaning device; the washing machine has an accommodating space for the ultrasonic cleaning device, and the ultrasonic cleaning device can be screwed in / out. in the accommodation space. The whole set of ultrasonic washing device is embedded in the washing machine and assembled with the washing machine as a whole, which does not affect the normal washing, but also adds a partial pre-washing function to the washing machine; the invention uses the cavitation effect of ultrasonic waves to send high-frequency waves locally to the initially wet clothes Ultrasonic waves emulsify oil stains and other stains under the action of the sound field, so that solid ions can be separated from the clothes, realize surface purification, and remove local stubborn stains to realize the partial pre-washing function of clothes.

Description

technical field [0001] The invention belongs to the field of cleaning equipment, and in particular relates to a washing machine with a partial pre-washing function. Background technique [0002] In real life, people often need to perform special treatment on parts when cleaning clothes, such as collars and cuffs in shirts, etc. If you do not use special local cleaning in advance, it is difficult to completely clean up the dirt on these parts; In addition, some local dirt such as lipstick marks, oil stains, and wine stains also need to be cleaned separately. At present, the washing machines on the market cannot be partially pre-washed, and the cleaning effect on stubborn stains is poor. And if hand rubs laboriously and damages clothes, detergent easily causes shortcomings such as environmental pollution. [0003] Ultrasonic cleaning is to use the cavitation effect (water molecule blasting) of ultrasonic waves in the liquid, the acceleration effect and the direct flow 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

[0005] Application document 201410354696.8 discloses a scheme of using an ultrasonic generating device for auxiliary laundry. In this scheme, a cleaning tank is additionally provided on the cover plate of the washing machine. Due to the large volume of the cleaning tank, too much space is occupied by the washing machine. In addition, when using When the cleaning tank is ultrasonically cleaned, it is not convenient to take the large clothes in the washing tub, which is extremely inconvenient to use, and the ultrasonic sounding device can be directly seen on the workbench of the washing machine. Although this method increases the The function of ultrasonic washing, but it has an impact on the overall appearance of the washing machine, and it is not conducive to the protection of the ultrasonic sounding device
