It is configured to include.

The low-water type electric washing machine using the electrolysis device and the neutralizing device of the present invention further includes an acidic electrolytic water flow passage control valve 317, a neutralizing device 319, a water level detecting unit 321, and a control unit 323 in a conventional washing machine. Characterized in that the position of the acidic electrolytic water storage container 315 is changed. Therefore, only the features of the present invention will be described except where necessary, and the operation and operation of the other components are the same as those of the related art, and thus detailed description thereof will be omitted.

Operation between the components of the present invention is as follows.

The electrolytic water amount control valve 303 adjusts the flow path of the washing water introduced from the outside. The electrolysis device 305 electrolyzes the neutral washing water flowing out through the electrolytic water control valve 303 into acidic electrolytic water and alkaline electrolytic water. The acidic electrolytic water storage container 315 stores the acidic electrolyzed water electrolyzed from the electrolysis device 305. The reservoir 309 is a neutral washing water separated through the electrolytic water control valve 303, alkaline electrolytic water electrolyzed from the electrolysis device 305 and acidic electrolyzed water flowing out of the acidic electrolyzed water storage container 315. It is supplied with a space for washing. The neutralizer 319 neutralizes the electrolytic acid and alkaline electrolyzed water. The acidic electrolyzed water passage control valve 317 is located between the acidic electrolyzed water storage container 315 and the reservoir 309 and selects a channel of the acidic electrolyzed water stored in the acidic electrolyzed water storage container 315 to store the reservoir 309 or Outflow to the neutralizing device (319). The water level detecting unit 321 is provided at a predetermined position on the wall surface of the reservoir 309 to detect a predetermined amount of washing water and / or alkaline electrolytic water. The control unit 323 controls the electrolytic water amount control valve 303 according to the amount of electrolytic water and neutral wash water to be obtained, and controls the flow path of the acidic electrolytic water flow path control valve 317 and the neutralization device 319 It controls whether or not the operation and the washing performance is controlled by the signal detected by the water level detection unit 321.

The operation of the present invention is as follows.

Washing water passing through the water supply valve 301 through the water inlet may be primarily separated from the electrolytic water amount control valve 303. The present invention can determine whether the detergent is injected by the user's desired choice. That is, when no detergent is used, the electrolytic water amount control valve 303 is adjusted to send the entire washing water passing through the water supply valve 301 to the electrolysis device 305. On the other hand, when the detergent is to be used, the electrolytic water amount control valve 303 is adjusted so that the entire washing water passing through the water supply valve 301 is introduced into the water storage tank 309 via the detergent dissolving device 307. In addition, when only a part of the incoming washing water is used as electrolytic water and a part is used as neutral washing water, the pH value of the desired electrolytic water may be set by appropriately adjusting the electrolytic water amount control valve 303. Depending on the amount of washing water separated from the electrolytic water control valve 303, the washing water of the reservoir 309 has an alkaline or weak alkaline property. The adjustment of the pH value can be controlled by the control unit 303 provided in the front panel portion. This is determined by the user according to the laundry material. In the case where the laundry is entirely put in the detergent, a detailed description thereof will be omitted since the same procedure as in the conventional washing machine is performed. Let's see if you want to use little or no detergent.

As described above, when no detergent is used at all or when only a part of the washing water is to be used as electrolytic water, all or part of the washing water flowing through the electrolysis device 305 is passed. As described in the prior art, the electrolysis device 305 electrolyzes the neutral washing water, and the decomposed alkaline electrolytic water flows directly into the washing tank 309 in the storage tank 309, and the acid electrolytic water is stored in the acid electrolytic water storage container 315. Flows into and is stored. The acidic electrolyzed water storage container 315 may be installed anywhere where there is sufficient space inside or outside of the washing machine, and the electrolysis device 305 and the acidic electrolyzed water storage container 315 are one or more separate. Conduits may be used to be fluidly connected to one another. The location of the acidic electrolytic water storage container 315 can be easily selected or changed by those skilled in the art. The water level detecting unit 321 is located at a suitable height such that the washing water or the electrolyzed water in the reservoir 309 can wash the laundry. The water level detection unit 321 located in the water tank 309 is gradually raised from the lower end of the washing water in the water storage tank 309 is notified to the control unit 323 when the water level detection unit 321 rises. Then, from that time, the rotary blade (not shown in the drawing) in the washing tank 311 rotates to start washing. After washing is finished, the acidic electrolyzed water is put in the water supply stage before the rinsing process, and when the laundry is rinsed with the acidic electrolyzed water, the bleaching effect occurs on the laundry, so that the bleaching effect can be obtained without using the bleach. The acidic electrolyzed water passage control valve 317 may be adjusted to select an acid electrolyzed water passage stored in the acidic electrolyzed water storage container 315. The selection of the acidic electrolytic water flow path may be controlled by the controller 303 provided in the front panel unit. The control unit 323 controls to wash the laundry with acidic electrolyzed water by inputting the acidic electrolyzed water in the water supply step before the rinsing process. This is also up to you. That is, if you want to wash the laundry is finished, the flow of the acid electrolytic water flows into the reservoir 309, if you do not want to bleach the flow of acidic electrolytic water flows directly into the neutralizer (319). This may be determined by the user in the control unit 323 according to the laundry material. The neutralizer 319 is for converting the electrolytic water flowing out of the reservoir 309 to neutral. The neutralizer 319 is commercially available. In other words, if the user wants a washing route entirely processed as before without using the electrolysis apparatus 305, the washing water in the water tank 309 is neutral, so that the neutralizing apparatus 319 does not work. On the other hand, if a user washes all or part of the washing water with alkaline electrolytic water using the electrolysis device 305, the acidic electrolytic water as much as the electrolytic alkaline electrolyzed water is stored in the acidic electrolytic water storage container 315. Simultaneously with the outflow is neutralized in the neutralizing device 319 and the neutral laundry is taken out of the washing machine.
