Description

Pasteurizing washing method by using silver solution

The present invention relates to a sterile washing method performed in a washing machine in which a silver solution forming unit is formed, and in particular, by spraying a silver solution prepared by the silver solution forming unit mounted inside the drum washing machine, The present invention relates to a sterile washing method using a silver solution to obtain a good bactericidal effect.

The washing machine performs the washing stroke, rinsing stroke, and dehydration stroke by rotating the drum, pulsator, and rod through the driving force of the motor.The washing machine is put together with the washing water and the laundry inside the rotating tub, and then stirred with them. It is a device that performs the washing using friction of the water and the rotating tub.

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. Rotate left and right alternately for a period of time.

Accordingly, a certain number of pulses are pulled by the sensing unit 2 in proportion to the amount of laundry in the washing tank, which is input to the control unit 3, and the control unit 3 counts the number of input pulses.

The controller 3 compares the measured number of pulses with a preset level level according to the number of pre-stored pulses to set an appropriate level and performs water supply by the set level, according to a preset algorithm. This can be done by washing, rinsing and dehydrating.

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, the washing process is performed by a predetermined process of performing water supply (St 5), washing (St 6), rinsing (St 7), and dehydration (St 8).

Particularly, referring to FIG. 3, a conventional dehydration process will be described. In order to dehydrate the water soaked in the conventional laundry cloth, the water is intermittently departed from the intermittent section P1 to gradually increase the rotational speed of the drum, and the first dewatered section during the intermittent section P1. After this is removed, the water is once again formed into a main stripping section P2 which is used to completely remove the water.

On the other hand, since there are many dirts on the laundry cloth, when a large number of laundry is combined and washed, contaminants are moved to another laundry cloth, and bad bacteria are moved and multiplied 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 portion formed in such a conventional washing machine is merely formed as one part of the washing machine, and thus no concrete reference has been made to what time it is appropriate to spray the sterilizing water at some time.

In particular, it is important to select the right time to spray the silver solution in order to obtain an effective sterilization effect while saving an expensive silver solution.

The present invention has been proposed to solve the above problems, and aims to increase the sterilization effect by proposing the correct time to spray the silver solution.

In addition, an object of the present invention is to propose a sterilization washing method using a silver solution by appropriately timing the spraying of the silver solution in a drum washing machine, thereby minimizing the use of silver and reducing the maintenance cost.

5 is a view illustrating a drum washing machine to which a method of washing meat using silver solution according to the present invention is applied.

Referring to FIG. 5, a silver solution reservoir 44, a water supply valve 45 connected to the silver solution reservoir 44 and formed in a washing water supply pipe through which water supplied from the outside flows, and the silver solution reservoir 44 And a supply valve 46 formed in the discharge pipe whose end is guided to the tub 41 as the discharge port of

The silver solution reservoir 44 is an electrode for dissolving silver ions when water is contained therein, the positive electrode body 47 having a purity of 99.9% or more as a positive electrode body, and silver ions in the wash water. A negative electrode body 48 used as an electrode opposed to the silver positive electrode body to melt, and a power supply unit 49 for supplying power to the positive electrode body 47 and the negative electrode body 48 are included.

Then, electrons come out of the negative electrode body 48. The silver ions are sterilized by performing a certain action with bacteria and fungi in a state of being contained in water.

6 is a flowchart sequentially illustrating a sterilization washing method using a silver solution according to the present invention.

Referring to FIG. 6, in the sterilization washing method according to the present invention, first, a power is turned on to turn on a washing machine (St 10), a specific washing course is selected (St 11), and the washing course is selected (St 11). ), The silver solution will be sprayed when the sterilization washing course or the lingerie washing course, etc., in which sterilization operation is preferably performed, is selected.

When the washing course is selected and washing starts to be performed, the degree of resistance to the forced rotation of the drum is evaluated by the operation of rotating the drum (St 12), and the quantity is detected by the evaluated resistance (St 13). After the amount of laundry is detected, washing (St 15), rinsing (St 16), dehydration (St 17), rinsing dehydration repetition, and final rinsing (St 18) are sequentially performed. The rinsing dehydration repeat and the last rinsing (St 18) is a process for completely removing the fine dirt or detergent residues on the laundry cloth, the more the number of repetitions will increase the cleanliness of the laundry cloth.

After the process as described above, after the fine dirt or detergent residue on the laundry cloth is completely removed, the sterilization process and the final dehydration process is performed by spraying the silver solution (St 19). The sterilization process is carried out at the beginning of the dehydration process so that after the dehydration is completely done, there is little silver solution left in the cloth, thereby preventing discoloration and discoloration of the cloth, which may be caused by a chemical reaction between the silver solution and the cloth. Do it.

When the above sterilization and final dehydration process is finished, all the washing process is finished, and when the laundry cloth is dried, it ends.

Hereinafter, the whole process of dehydration is proposed in detail by the graph of the rotational speed and time of the drum in the sterilization and final dehydration.

7A to 7D are diagrams showing an embodiment of a dehydration process in which silver laundering is performed.

First, in FIG. 7A, after the drum stops rotating for a predetermined period while the conventional separation section (see P2 in FIG. 3) is performed, the drum is rotated at a low speed again, and the inside of the drum is rotated for a predetermined time ( Allow silver solution to be sprayed during t1). The drum rotational speed at the time when the silver solution is sprayed is called R3, and the drum rotational speed in the separation section is called R1.

Said R1 may be the highest speed of the drum being rotated for dehydration at a high speed. And, R3 is a rotation speed such that the laundry cloth accommodated in the drum can fall down when the drum reaches the highest point while the drum is rotated together by rotation. In other words, if the drum's rotational speed is high, the laundry cloth is rotated together by the centrifugal force on the inner circumferential surface of the drum, and when the speed is gradually slowed down, the laundry cloth rotated like the drum cannot be rotated like the drum, It will fall by, where the speed of the drum can be called R3. In other words, the rotational speed of the drum when the laundry cloth rotated in the drum adheres to the inside of the drum, rotates, and then falls down from the highest point to the lower side of the drum. As such, by placing the laundry cloth in the drum in the up and down direction, the silver solution may be sprayed on the front surface of the laundry cloth, and the sterilization effect may be increased.

Since much water is dehydrated during this dehydration process, the dilution of the silver solution can be prevented to maximize the sterilization effect of the silver solution. However, if the drum is stopped for a while during the separation period, the drum is rotated at a low speed again. It is not preferable because much time elapses for dehydration. This dehydration stroke can be applied to a lingerie or inner wash course where sterilization must be completed.

In FIG. 7B, in order to solve the above-mentioned problem, the drum does not completely stop rotation during the separation period, and when the drum rotation speed reaches R3, spraying the silver solution for a predetermined time t2, the time for dehydration It is possible to obtain the sterilization effect by the silver solution without wasting waste.

In the dehydration method such as A) and B) of FIG. 7, the sterilization action by the silver solution may occur smoothly, but a large amount of silver ions may not remain dehydrated even after dehydration has elapsed, and thus may remain in the laundry cloth. There is a fear that discoloration of the laundry cloth occurs due to a chemical reaction with the laundry cloth. This dehydration stroke can be applied to either the washing course or the strong sterilization course in which sterilization must be completed.

7C is to improve the problems as described above, before performing the separation section is performed by decanting at a medium speed (R2) for a predetermined time, so that most of the water is dehydrated in the laundry cloth, Stop the drum rotation. Since the rotation of the drum is stopped, the laundry falls to the lower side of the drum, so that the laundry cloth is collected in one direction of the drum.

Once the drum is stopped, spraying the silver solution while rotating the drum again at low speed (R3) for a certain time (t3) and then performing the enthalation for the remaining time at high speed (R1) may remain in the wash cloth. The amount of silver solution present will be reduced to a small amount. In such a case, the silver solution which may remain in the laundry cloth is reduced, thereby preventing the discoloration of the laundry cloth.

However, after the drum is rotated at an intermediate speed R2, spraying the silver solution while rotating the drum at a low speed R3 without stopping the drum rotation can reduce the time for the dehydration stroke. However, since the laundry cloth attached to the inner circumferential surface of the drum may not fall during the high speed rotation, it is not preferable.

7D is characterized in that the silver solution is sprayed by rotating at a low speed (R3) when the initial liver degassing of the dehydration stroke is performed.

This dehydration process may have a small sterilization effect because the silver solution is diluted, but since most of the silver solution is removed from the laundry cloth, discoloration of the cloth can be completely prevented.

This dehydration stroke can be applied to standard sterilization laundering courses or quick laundering courses.

According to the present invention, it is possible to perform the dehydration stroke suitable for the laundry cloth by suggesting the correct timing of spraying the silver solution according to the laundry cloth.

In addition, the present invention by appropriately timing the spraying of the silver solution in the drum washing machine, it is possible to minimize the use of silver to reduce the maintenance cost.

In addition, there is an advantage that can increase the user's satisfaction by the appropriate dehydration stroke according to the situation.
