Technical Field
The utility model relates to a washing machine technical field particularly, relates to a drum type washing machine's outer bucket in back, including this outer bucket in back outer bucket, including this outer bucket's drum type washing machine's barrel subassembly and including this barrel subassembly's drum type washing machine.
Background
After the drum washing machine is used for a long time, a lot of dirt can be accumulated between the inner barrel and the outer barrel of the washing machine. These soils are often bound between the inner and outer tubs and are difficult to wash off during the laundering process.
To address these problems, most current washing machines are provided with a "canister self-cleaning procedure". The user runs the program to clean the inner and outer barrels and the door seals of the washing machine. However, the current design of a barrel self-cleaning program is single, and for stubborn stains on the inner barrel and the outer barrel of the washing machine, the washing is carried out by water flow basically, the water flow washing has extremely limited decontamination effect on the washing machine, and only the inner surface of the washing machine can be cleaned; in the case of metal parts such as inner tubs, tripods and the like, more stains are generated due to corrosion (such as rusty spots) caused by the internal humid environment, and the stains cannot be cleaned by water flow.

An embodiment of the third aspect of the present invention provides a drum assembly (not shown in the figure) of a drum washing machine, comprising: an inner tub and an outer tub as in any one of the embodiments of the second aspect, fitted around the inner tub.
The embodiment of the third aspect of the present invention provides a barrel assembly, which comprises an outer barrel according to any one of the embodiments of the first aspect, and therefore has all the advantages of any one of the embodiments, and will not be described herein again.
An embodiment of the fourth aspect of the present invention provides a drum washing machine (not shown in the drawings), comprising a tub assembly as in the embodiment of the fourth aspect.
The embodiment of the fourth aspect of the present invention provides a drum washing machine, which has all the advantages of any one of the above embodiments due to the barrel assembly of the third aspect of the present invention, and is not repeated herein.
In the above embodiment, the plurality of ultrasonic transducers 20 of the tub assembly are electrically connected to the electric control board of the drum washing machine.
The ultrasonic transducers 20 are electrically connected with the electric control board of the drum washing machine, and can automatically work under the control of the electric control board, so that the automation degree of the washing machine is improved. Of course, the ultrasonic transducer 20 may also be electrically connected to a mobile terminal (such as a mobile phone, a computer, a remote controller, etc.) through a wireless module, and controlled by the mobile terminal.
Further, the drum washing machine further includes an ultrasonic generator, which may be installed on an electric control board of the drum washing machine, or may be installed at a position on the outer tub adjacent to the ultrasonic transducer 20, or at another position isolated from water in the drum washing machine. The ultrasonic generator is electrically connected to the ultrasonic transducer 20, the ac mains supply is converted into a high-frequency ac electrical signal matched with the operating frequency of the ultrasonic transducer 20 by the ultrasonic generator, and the high-frequency ac electrical signal is transmitted to the ultrasonic transducer 20, and the ultrasonic transducer 20 generates high-frequency vibration according to the received high-frequency ac electrical signal to generate ultrasonic waves.
The drum washing machine provided by the present application will be described in detail with reference to a specific embodiment.
The utility model provides a drum type washing machine, at outer barrel bottom installation ultrasonic transducer, through ultrasonic transducer production ultrasonic energy, ultrasonic energy can constantly make dirt material disperse, loose, broken destroy, drop under the ultrasonic wave effect through cavitation physical action in liquid, and do not adhere to on the pipe wall easily to the effect of ultrasonic wave scale removal has been reached.
Wherein, the cavitation generates energy to break up large particles of dissolved substances (detergent, etc.) in water into small particles, accelerate the dissolution of the detergent, and improve the cleaning effect.
Meanwhile, during the ultrasonic treatment, when high-intensity ultrasonic waves are propagated in a liquid medium, longitudinal waves are generated, thereby generating regions which are alternately compressed and expanded, and these regions of pressure change are liable to cause a cavitation phenomenon and form micro bubble nuclei in the medium. At the moment of adiabatic shrinkage and collapse, the micro bubble nucleus internally presents high temperature above 5000 ℃ and pressure of 50000kPa, so that certain bacteria in the liquid are killed, viruses are inactivated, and even cell walls of a few microorganisms with small volume are damaged, thereby achieving the effect of sterilization.
Further, the current drum washing machine is generally composed of an inner tub and an outer tub, and the inner tub rotates forward and backward and the outer tub is fixed during washing or dewatering. Because the space of the inner barrel body of the washing machine is large, ultrasonic energy is dispersed and propagated in a medium (water) (similar to fan-shaped propagation), the ultrasonic energy can generate energy reflection when meeting objects (an outer barrel and an inner barrel), and part of the energy can be absorbed by the objects. Therefore, the cleaning effect of a single ultrasonic transducer is limited, so that the number of the ultrasonic transducers is not less than 2.
Considering that the inner part of the washing machine is more dirty in the rear outer barrel than in the front barrel, the ultrasonic transducer needs to be placed in the rear half part of the outer barrel when being installed, so as to achieve better cleaning effect. In addition, the ultrasonic transducers are generally installed at the bottom of the rear half of the tub and arranged in the axial direction of the "tub" as shown in fig. 1, in consideration of the fact that the curvature of the tub is relatively smoothest in the bottom region (the reference is a plurality of ultrasonic transducers installed at the front and rear sidewalls) and the influence of the motor pair.
Compared with the traditional cylinder self-cleaning program, the scheme is particularly added with an ultrasonic washing mode, and depends on the 'cavitation effect' of ultrasonic waves to 'peel off' stubborn stains, so that the cleaning effect of the inner and outer cylinders is enhanced, the self-cleaning function of the ultrasonic cylinder of the washing machine is realized, and meanwhile, the washing powder can be dissolved by utilizing the ultrasonic waves, and the sterilization function is realized by utilizing the ultrasonic waves.
