Description

Technical Field

[0001] The present invention belongs to the technical field of electrolyzed water washing machines, and particularly relates to a washing machine electrolyzed water system. Background Art

[0002] Washing machines are common household appliances. With the development of washing machine technology, fully automatic washing machines have entered thousands of households. The existing fully automatic washing machines mainly include two types: pulsator washing machines and drum washing machines. Traditional washing machines mainly rely on adding washing powder or laundry detergent to the washing water to achieve the cleaning effect of clothes, which inevitably causes a certain degree of water pollution problem. In recent years, electrolyzed water washing machines have emerged. An electrolyzed water device is added to the washing machine, and a DC power supply is provided to the anode and cathode of the electrolyzed water device to electrolyze the washing water, generating negative oxygen ions and hydroxide ions. Through the high permeability of ionic water and the decomposition and adsorption of stains and dust by ions, the effect of removing stains on clothes is achieved, which can effectively solve the pollution problem of washing water. At the same time, active oxygen and hypochlorous acid are also produced after electrolyzing water. Among them, hypochlorous acid has the property of sterilization, so that the clothes also have a certain sterilization effect during the washing process. However, the electrolytic water tank of the existing electrolyzed water washing machines is installed outside the rotating inner cylinder of the washing machine. For example, the electrolytic water tank of the fully automatic ultrasonic washing machine with disinfection and sterilization disclosed in the patent document CN209194195U. Part of the acidic and alkaline substances generated by electrolyzing water will be neutralized during the process of entering the rotating inner cylinder, thus reducing the stain removal and sterilization effects. In addition, dirt and bubbles are likely to adhere to the two electrolytic electrodes of the existing electrolyzed water washing machines, resulting in unsatisfactory electrolysis efficiency. The above problems seriously limit the popularization and application of electrolyzed water washing machines. Therefore, it is urgent to improve the technology of the electrolyzed water system of washing machines. Summary of the Invention

[0003] In view of the above situation, the present invention designs a washing machine electrolyzed water system, which can prevent a large amount of dirt and bubbles from adhering to the electrolytic electrodes, improve the electrolysis efficiency of the washing water, and the active factors generated by electrolyzing water can directly act on the washed clothes, which is beneficial to improving the cleaning and sterilization effects of washing.

[0004] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0005] A washing machine water electrolysis system comprises a fixed outer shell of the washing machine and a rotating inner drum for containing washing water, wherein the rotating inner drum is sleeved in the fixed outer shell, the rotating inner drum comprises a drum wall and a drum bottom, the drum wall is a circular tubular structure, the drum bottom is a circular disc-shaped structure, a conductive inner wall and a conductive inner bottom are respectively arranged on the inner sides of the drum wall and the drum bottom, the drum bottom is coaxially fixed to the bottom of the drum wall through an annular insulating base, the conductive inner wall and the conductive inner bottom are insulated from each other, the conductive inner wall and the conductive inner bottom are respectively used as two electrodes for electrolyzing water, a DC power supply for supplying a safe voltage to the two electrodes is arranged on the outer side of the fixed outer shell of the washing machine, and the conductive inner wall and the conductive inner bottom are respectively electrically connected to two output ends of the DC power supply.

[0006] Preferably, the conductive inner wall and the conductive inner bottom are both made of metal, more preferably stainless steel, which has good conductivity and strong corrosion resistance, can well resist the acid and alkali corrosion of electrolyzed water, and improve the electrolysis efficiency and service life of the washing machine. The insulating base is made of plastic, more preferably nylon, which is strong and durable, has good insulation, and ensures the insulation resistance between the conductive inner wall and the conductive inner bottom.

[0007] Preferably, the DC power supply adopts an AC / DC power supply module that converts AC voltage into a safe voltage. The input end of the DC power supply is connected to a 220V AC voltage, and the output voltage between the positive and negative poles of the DC power supply output end is a safe voltage below 42V, further preferably a human body safety voltage below 36V, and further preferably a human body safety voltage that can be continuously contacted below 24V to prevent electric shock accidents.

[0008] When the washing machine is a pulsator washing machine, a pulsator is arranged above the bottom of the rotating inner drum, a pulsator power shaft is coaxially connected below the pulsator, the pulsator power shaft is drivingly connected to the inner drum drive shaft, the inner drum drive shaft is rotatably connected to the fixed outer shell of the washing machine through a metal seat bearing, the elastic contact is a conductive metal sheet, an annular sliding contact is coaxially fixed to the outer wall of the rotating inner drum, the sliding contact is in sliding contact with the elastic contact, the sliding contact is electrically connected to an output end of a DC power supply through the elastic contact, the upper surface of the pulsator is a metal surface, preferably made of stainless steel, the upper surface of the pulsator is electrically connected to the other output end of the DC power supply through the pulsator power shaft, the inner drum drive shaft, the seat bearing and the ground in sequence. The metal upper surface of the pulsator of the pulsator washing machine is used as a conductive inner bottom, and the conductive inner wall of the rotating inner drum is used as two electrolytic electrodes for electrolyzing water, respectively. The pulsator is also rotating and stirring the washing water and washing clothes during the washing process, which can also effectively prevent dirt and bubbles from being deposited and attached.

[0009] Further, the conductive inner wall is electrically connected to the sliding contact. An elastic contact that makes sliding contact with the sliding contact is arranged outside the sliding contact. The sliding contact is slidably and electrically connected to an output terminal of the DC power supply through the elastic contact. That is, the conductive inner wall of the rotating inner cylinder can be connected to either the positive or negative pole of the output terminal of the DC power supply.

[0010] Further, an inner cylinder drive shaft is coaxially and fixedly connected to the outside of the bottom of the rotating inner cylinder. The conductive inner bottom is electrically connected to the inner cylinder drive shaft through the agitator power shaft. The inner cylinder drive shaft is electrically connected to the other output terminal of the DC power supply through a pedestal bearing and a ground connection. If the conductive inner wall of the rotating inner cylinder is connected to the positive pole of the output terminal of the DC power supply, then its conductive inner bottom is connected to the negative pole of the output terminal of the DC power supply; if the conductive inner wall of the rotating inner cylinder is connected to the negative pole of the output terminal of the DC power supply, then its conductive inner bottom is connected to the positive pole of the output terminal of the DC power supply.

[0011] When the washing machine is a drum washing machine, the bottom of its rotating inner cylinder is a disc-shaped structure. The bottom of the cylinder is fixedly connected to the bottom of the cylinder wall through an annular insulating base. An inner cylinder drive shaft is coaxially and fixedly connected to the outside of the bottom of the cylinder. The inner cylinder drive shaft is rotatably connected to the fixed outer shell of the washing machine through a pedestal bearing made of metal. A sliding contact is arranged at the outer end of the inner cylinder drive shaft. The conductive inner wall is electrically connected to the sliding contact. An elastic contact is arranged outside the sliding contact. The elastic contact makes sliding contact with the sliding contact. The conductive inner wall is electrically connected to an output terminal of the DC power supply through the sliding contact and the elastic contact. The conductive inner bottom is electrically connected to the other output terminal of the DC power supply through the inner cylinder drive shaft, the pedestal bearing and the ground connection.

[0012] That is, the conductive inner wall and the conductive inner bottom respectively serve as the two electrolysis electrodes for electrolyzing water. The above two connections of the anode and cathode electrodes can both achieve the purpose of electrolyzing water. Compared with the existing electrolytic water washing machines, in the present invention, during the laundry process, both the conductive inner wall and the conductive inner bottom will rotate, and the laundry water and the washed clothes will roll and rotate in the rotating inner cylinder. There will be continuous collision and friction between the washed clothes and the conductive inner wall and the conductive inner bottom. This can well prevent dirt and bubbles from depositing and adhering to the electrolysis electrodes. On the one hand, it is beneficial to improve the electrolysis efficiency; on the other hand, since the conductive inner wall and the conductive inner bottom serving as the two electrodes are both arranged inside the rotating inner cylinder, the electrolysis reaction occurs inside the rotating inner cylinder. In this way, the process of transporting the electrolyzed water from the electrolysis water tank to the inside of the rotating inner cylinder is omitted, avoiding the loss of acid-base neutralization during the transportation of the electrolyzed water. Active factors such as negative oxygen ions, hydroxide ions, reactive oxygen species, and hypochlorous acid generated by the electrolyzed water can directly and effectively act on the washed clothes, thereby improving the cleaning effect and sterilization effect of the washed clothes.

[0013] The present invention also includes other components that enable it to be used normally, which are all conventional means in the art. In addition, for the devices or components not defined in the present invention, such as the clutch, drive motor, water inlet system, drainage system, water level detection system of a pulsator washing machine, and the automatic control system of a washing machine, etc., the existing technologies in the art are adopted.

[0014] The beneficial effects of the present invention are as follows:

[0015] The electrolyzed water system of the washing machine provided by the present invention completely changes the setting mode of the electrolysis electrodes of the existing electrolyzed water washing machines, prevents the electrolysis electrodes from adhering to dirt and bubbles, and improves the electrolysis efficiency of the washing water; and the electrolyzed water of this washing machine electrolyzed water system directly contacts and acts on the washed clothes, avoiding the acid-base neutralization reaction and the loss of active ions generated during the transportation process of the electrolyzed water of the existing electrolyzed water washing machines, which is beneficial to improving the cleaning effect and sterilization effect of the washed clothes.
