Washing machine with partial pre-washing function

Abstract

The invention discloses a washing machine with a partial pre-washing function. The washing machine comprises an ultrasonic washing device; the washing machine is provided with an accommodating space for accommodating the ultrasonic washing device, and the ultrasonic washing device can be arranged in the accommodating space in a screw-in / screw-out manner. The whole ultrasonic washing device is embedded in the washing machine and integrally assembled with the washing machine, normal clothes washing is not influenced, and the washing machine is also endowed with the partial pre-washing function.The washing machine partially emits high-frequency ultrasonic waves to initially-wet clothes by utilizing the cavitation function of the ultrasonic waves, so that stains such as oil stains are emulsified under the function of a sound field, solid ions are separated from the clothes, surface purification is achieved, partial stubborn stains are removed, and the partial pre-washing function on the clothes is achieved.

Description

Technical field [0001] The invention belongs to the field of cleaning equipment, and specifically relates to a washing machine with a partial pre-washing function. Background technique [0002] In real life, people often need to perform special treatments on parts when cleaning clothes, such as the collar and cuff positions in shirts. If special local cleaning is not used in advance, it will be difficult to thoroughly clean up the dirt in these locations; In addition, some local dirt such as lipstick marks, oil stains, and wine stains also need to be cleaned separately. The current washing machines on the market cannot be partially pre-washed, and have poor washing effect on stubborn stains. And if the hand rubs laboriously and damages the clothes, the detergent is likely to cause environmental pollution and other disadvantages. [0003] Ultrasonic cleaning is the use of ultrasonic cavitation (water molecule blasting), acceleration and direct flow in the liquid to directly and in...

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
