Washing Machine with Internal Cleaning Part

The present invention relates to a washing machine having a cleaning part on the outer surface of an internal washing tub, and more particularly, it is located inside the washing machine and removes contaminants deposited in the space between the washing tub and the water storage tub, which is difficult for the user to physically clean without separate disassembly. technique to remove it.

A washing machine is a machine that cleans textiles such as clothes, towels, quilts and blankets.

Washing machines are mainly powered by an electric motor and use detergent and water to perform washing, rinsing and spin-drying processes to remove contaminants from clothes, etc. It consists of a delivery machine part, a control part that controls the washing process, and a water supply device and drainage system for putting water in and out.

The washing machine has a vortex type in which water is vortexed by turning a rotary blade with an electric motor according to a method of rotating the laundry, an agitating type in which the washing tub is rotated left and right alternately, and a drum method in which the entire tub is returned. There are two types of washing methods: the drum method, which washes by rotating the whole barrel, and the pulsator method, which washes by rotating the washing blades. Referring to FIG. 2 showing a generally used household washing machine, a water storage tub is located inside a main body of the washing machine, and a washing tub rotated by a driving unit is located inside the water storage tub. When a rotating member for agitating laundry is installed on the bottom surface of the washing tub during washing, a driving unit for rotating the rotating member of the washing tub is installed at a lower portion of the water storage tub.

A washing process of the washing machine configured as described above will be described as follows.

First, when laundry is put into the washing tub inside the main body of the washing machine and a predetermined detergent is put in, and then the washing machine is driven, washing water is supplied and the driving unit operates to rotate the washing tub and the rotating member to wash the laundry in the washing tub. Thereafter, after discharging all the water used for washing, a rinsing process is performed, and when the rinsing process is completed, all the water used for rinsing is discharged and a dehydration process of rotating the washing tub at high speed is sequentially performed.

However, as shown in FIG. 1, during the washing process as described above, various foreign substances such as fibrous tissue or hair separated from the laundry are mixed, as well as detergent residue, oil scale, water scale, etc., on the inner surface of the water tank. However, while sticking to and remaining on the outer surface of the washing tub, not only the inner surface of the water storage tub or the outer surface of the washing tub is contaminated, but if such contamination is prolonged, mold or various bacteria may be propagated and an odor may be generated. In addition, there is a problem in that the laundry, which has been washed using the washing machine, is rather contaminated with various molds or bacteria, or an unpleasant odor is generated from the laundry even after washing.

In order to solve the above problems, it is preferable to periodically remove contaminants attached to the water storage tub and the washing tub.

However, since the water storage tub and the washing tub are located inside the washing machine body, disassembly of the washing machine is inevitable for washing, but it is not easy for general users to disassemble and wash the washing machine. In some cases, it is entrusted to a washing machine cleaning company, but there is a cost burden.

Accordingly, Korean Patent Laid-Open Publication No. 10-2014-0062981 discloses a washing machine that can be easily detached for cleaning the inside of the washing tub, but in the end, the user has to disassemble and clean the washing machine and then reassemble the washing machine.

In addition, exclusive detergents for washing washing tubs are on the market, but these exclusive detergents use chemical components to remove attached contaminants, and there is a limit to cleaning contaminants cleanly, and there is a concern that environmental problems may occur due to the use of chemical components. there is
