Ultrasonic washing drum device of washing machine

Abstract

The invention relates to an ultrasonic washing drum device of a washing machine. The ultrasonic washing drum device comprises an outer barrel body, an inner barrel body and an ultrasonic transducer module, wherein the ultrasonic transducer module is a waterproof sheet-shaped ultrasonic transducer sheet which consists of a sheet-shaped sealing covering shell and a plurality of ultrasonic transducers; the waterproof sheet-shaped ultrasonic transducer sheet is fixedly arranged on the inner cavity wall of the outer barrel body along inner cavity wall of the outer barrel body in a circular manner;or the ultrasonic transducer module is a waterproof strip-shaped ultrasonic transducer belt which is formed by coating a plurality of ultrasonic transducers through the strip-shaped sealing covering shell; and the waterproof strip-shaped ultrasonic transducer belt is fixedly arranged on the inner cavity wall of the outer barrel body along the inner cavity wall of the outer barrel body in a circular manner. According to the ultrasonic washing drum device disclosed by the invention, dirt on the outer barrel body and the inner barrel body cannot hide, and is completely cleared, so that the washing machine is kept clean and sanitary; and in a washing process of the washing machine, three-dimensional packaged type ultrasonic cavitation effect is formed on clothes when the ultrasonic transducermodule works, so that cleaning degree of the clothes is better.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine with an ultrasonic function, in particular to a washing tub device with an ultrasonic function used on a washing machine. Background technique [0002] Washing machine is one of indispensable electric appliances in people's household life, is divided into top-opening pulsator washing machine and side-opening drum washing machine. In the daily use of washing machines, whether it is a top-loading washing machine or a drum washing machine, what often troubles people is the cleaning problem of dirt hidden on the side wall between the outer cylinder and the inner cylinder of the washing machine. Because the place where the dirt is stored belongs to the working gap of relative rotation between the outer cylinder and the inner cylinder, the space is very narrow and cannot be cleaned manually. The main means to solve this cleaning problem at this stage is to pour specia...

AI Technical Summary

Problems solved by technology

However, in practical applications, the current way of arranging ultrasonic transducers on the outer wall of the outer cylinder of the washing machine still has certain defects and imperfections, which are mainly reflected in: the location near or at the ultrasonic cavitation source The area, that is, the position of the ultrasonic transducer, is strongly affected by ultrasonic cavitation, and the effect of cleaning clothes and dirt on the wall of the cylinder is more obvious, and the cleaning degree is better; while the area far away or far away from the ultrasonic cavitation source, then Due to the weak cavitation effect of ultrasonic waves, the cleaning effect and dirt removal effect of clothes are poor, and even the cleaning is not in place.

However, the existence of these phenomena or problems mentioned above is mainly due to the layout, structural design, and working style of the ultrasonic transducer, and there are still places where the design is not scientific, reasonable, or in place.
