1 is a block diagram showing the configuration of a conventional washing machine.

Referring to FIG. 1, a key input unit 1 for inputting a user's request command, a sensing unit 2 providing information for controlling a stroke of a washing machine by sensing voltage, water temperature, and water level, and the sensing The control unit 3 controls the operation state of the entire washing machine according to the detection signal detected by the unit 2, and when the operation button is input through the key input unit 1 according to the control signal of the sensing unit 2 A display for displaying an operation state according to a function selected through the key input unit 1 according to a load driver 4 for driving a load such as a motor, a water supply valve, a drain valve, and the control signal of the controller 3. It consists of a part (5).

The driving method of the washing machine as described is briefly described. When a user puts a cloth into a washing tank and applies power, and presses a predetermined key on the key input unit 1 to input a washing instruction, the control unit 3 applies a control signal to the load driving unit 4 to operate the motor.

2 is a view for explaining a washing method of a conventional washing machine.

Referring to FIG. 2, the washing machine is turned on (St 1). Then, the user selects the desired washing course (St 2), and presses the operation button (St 3).

When the operation button is input, the amount of the laundry cloth in the washing tank is sensed (St 4). Then, according to the amount of laundry cloth detected, washing is performed by a predetermined process of performing water supply (St 5), washing (St 6), rinsing (St 7), and dehydration (St 8).

In addition, since there is a lot of dirt on the laundry cloth, when a large number of laundry is combined and washed, contaminants are moved to another laundry cloth, and there is a problem that bad bacteria are transferred and propagated throughout the laundry. In particular, underwear such as lingerie is an article directly touching the human body, which causes many problems when bacteria are moved and multiplied.

In order to improve such a problem, recently, more and more antimicrobial agents are used during washing, and the increasing use of antimicrobial agents adversely affects the health of users.

Therefore, in recent years, a method of washing is proposed using a natural antibiotic silver (Ag), as a specific embodiment of the Korean Patent Publication No. 2002-0012368, "Sterile water supply of the washing machine" , Korean Patent Laid-Open No. 2002-0012369, has been proposed by the "control method of a washing machine having a silver solution manufacturing apparatus".

However, the silver solution forming mechanism formed in the conventional washing machine has a problem that the silver solution in which silver ions are accommodated again precipitates inside the silver solution reservoir and pollutes the inside of the silver solution reservoir. There is a problem that the tube is blocked.

Furthermore, since the concentration of silver ions in the silver solution is lowered due to the deposited silver ions, there are many problems in that there is no effect of sterilization by the silver solution.

In particular, the poor use of silver ions in the silver solution formation structure in which expensive silver is used is a big problem.

The present invention is proposed to solve the above problems, and an object of the present invention is to propose a silver solution forming structure of a washing machine in which silver ions are produced only when necessary.

In addition, it is an object of the present invention to propose a silver solution forming structure of a washing machine that prevents silver ions contained in the silver solution from being precipitated as silver particles again, thereby increasing silver's utility value.

Moreover, since the density | concentration of silver solution can be adjusted precisely, it aims at suggesting the silver solution formation structure of the washing machine which can exactly match the density | concentration of silver ion required for washing | cleaning.

In addition, it is an object of the present invention to propose a silver solution forming mechanism of a washing machine that allows silver ions to be produced more quickly, thereby minimizing the precipitation of silver ions and allowing the silver solution to be supplied quickly.
