Description

Technical Field

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

[0002] Washing machines are common household appliances. Traditional washing machines primarily rely on adding detergent or liquid laundry detergent to the wash water to achieve a cleansing effect, inevitably causing water pollution. In recent years, electrolytic water washing machines have emerged. These machines incorporate an electrolytic water device to generate negative oxygen ions and hydroxide ions. These devices utilize the high permeability of ionized water and the ions' ability to decompose and adsorb stains and dust, effectively removing stains from clothing. Furthermore, electrolysis also produces reactive oxygen species and hypochlorous acid, which has bactericidal properties and thus has a certain sterilizing effect on clothing during the washing process. However, the electrolytic water tanks of existing electrolytic water washing machines are typically mounted outside the rotating inner drum of the washing machine. The acidic and alkaline substances generated by the electrolytic water are partially neutralized upon entering the rotating inner drum, reducing the stain removal and sterilization effectiveness. Furthermore, dirt and bubbles easily adhere to the two electrolytic electrodes of existing electrolytic water washing machines, resulting in suboptimal electrolysis efficiency. Therefore, further technical improvements to the electrolytic water systems of washing machines are urgently needed. Summary of the Invention

[0003] In response to the above situation, the present invention designs a water electrolysis system for a washing machine, which improves the electrolysis efficiency of laundry water, and the active factors generated by electrolyzed water can directly act on the washed clothes, which is beneficial to improving the cleaning and sterilization effects of the washing machine.

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

[0005] A water electrolysis system for a washing machine comprises a fixed outer shell of the washing machine and a rotating inner drum for holding washing water, the rotating inner drum being rotatably arranged on the inner side of the fixed outer shell, and a first electrode and a second electrode for electrolyzing washing water being fixedly arranged on the inner bottom of the rotating inner drum, the two electrodes being coaxially sleeved together, and a certain isolation gap being left between the two electrodes; a first annular contact and a second annular contact are arranged on the outer side wall of the rotating inner drum, and the two annular contacts are respectively electrically connected to the two electrodes; a rotating rod is provided on the side wall of the fixed outer shell, and the rotating rod is rotatably connected to the fixed outer shell, and a first brush contact and a second brush contact are provided on the upper end of the rotating rod, and the two brush contacts are respectively electrically connected to the two annular contacts in an openable and closable sliding manner; a direct current power supply for providing power for electrolyzing water is provided on the outer side of the rotating inner drum, and two output ends of the direct current power supply are respectively electrically connected to the two brush contacts.

[0006] Furthermore, the rotating inner cylinder is a cylindrical structure, with two annular contacts fixedly sleeved on the outer wall of the rotating inner cylinder from top to bottom. The two annular contacts are insulated from each other and electrically connected to the two electrodes via wire 1 and wire 2, respectively. Two brush contacts are fixedly mounted on the upper end of the rotating rod from top to bottom and are insulated from each other. A torsion lever for driving the rotating rod to rotate is provided at the lower end of the rotating rod, and a return spring for driving the rotating rod to rotate and reset is provided between the rotating rod and the fixed housing. A drive motor is provided outside the fixed housing, and the output end of the drive motor is transmission-connected to the torsion lever via a pull rope.

[0007] Furthermore, the DC power supply utilizes an AC / DC power supply module that converts AC voltage into a safe DC voltage. The two output terminals of the DC power supply are electrically connected to the two brush contacts via wires 1 and 2, respectively. The DC power supply input is connected to a 220V AC voltage, and the output voltage between the positive and negative terminals of the DC power supply output is a safe voltage of 42V or less, more preferably a human-safe voltage of 36V or less, and even more preferably a human-safe voltage of 24V or less, to prevent electric shock accidents.

[0008] As a preferred embodiment, both electrodes are annular in structure. The first electrode is coaxially fixed to the inner wall of the rotating inner drum, and the second electrode is coaxially fixed to the inner side of the first electrode, with an insulating pad placed between the two electrodes. The second electrode may also be provided with a plurality of filter mesh holes, which not only increases the water flow rate of the electrode itself but also provides a filtering and purification function, filtering out hair debris and impurities in the laundry water.

[0009] As another preferred embodiment, electrode one includes a conductive ring one and several electrolytic fins one, electrode two includes a conductive ring two and several electrolytic fins two, conductive ring two is coaxially sleeved in the middle of conductive ring one, each electrolytic fin one is radially arranged on the inner wall of conductive ring one, each electrolytic fin two is radially arranged on the outer wall of conductive ring two, and each electrolytic fin one is staggered with each electrolytic fin two.

[0010] The present invention also includes other components that enable normal use, which are conventional means in the field. In addition, devices or components not limited in the present invention all adopt existing technologies in the field.

[0011] The beneficial effects of the present invention are as follows:

[0012] The electrolytic water system of the washing machine provided by the present invention has a simple electrode structure and low manufacturing cost. It completely changes the setting method of the electrolytic electrodes of the existing electrolytic water washing machines, prevents the electrolytic electrodes from adhering to dirt and bubbles, and improves the electrolysis efficiency of the washing water.

[0020] The rotating inner cylinder is a cylindrical structure. Two annular contacts are fixedly mounted on the outer wall of the rotating inner cylinder from top to bottom. The two annular contacts are insulated from each other and electrically connected to the two electrodes via wire 13 and wire 2 14, respectively. Two brush contacts are fixedly mounted on the upper end of the rotating rod from top to bottom. The two brush contacts are insulated from each other and can swing with the rotation of the rotating rod, thereby achieving an openable and sliding electrical connection with the two annular contacts.

The DC power supply input is connected to a 220V AC voltage, while the output terminal provides a safe 24V DC voltage. A current sensor 22 is also provided on wire 1 or wire 2.

[0022] like Figure 2 As shown, both electrodes are of annular structure. Electrode 1 is fixed on the inner wall of the rotating inner cylinder, and electrode 2 is coaxially fixed on the inner side of electrode 1. The two electrodes are fixedly connected by an insulating bolt 11, which is convenient for maintenance and replacement of the electrodes, especially for the replacement of anodes that are prone to electrolytic corrosion after long-term use. An insulating pad 12 is also provided between the two electrodes, and a plurality of filter mesh holes 21 are opened on electrode 2.

[0023] Example 2

[0024] like Figure 1 As shown, a water electrolysis system for a washing machine includes a fixed outer shell 1 of the washing machine and a rotating inner drum 2 for holding washing water, the rotating inner drum being rotatably disposed inside the fixed outer shell, and having fixedly disposed on the bottom of the inner side of the rotating inner drum an electrode 3 and an electrode 2 4 for electrolyzing washing water, the two electrodes being coaxially sleeved together with an isolation gap left between the two electrodes; an annular contact 1 5 and an annular contact 2 6 are disposed on the outer side wall of the rotating inner drum, the two annular contacts being respectively electrically connected to the two electrodes; a rotating rod 7 is disposed on the side wall of the fixed outer shell, the rotating rod being rotatably connected to the fixed outer shell, and a brush contact 1 8 and a brush contact 2 9 are disposed on the upper end of the rotating rod, the two brush contacts being respectively electrically connected to the two annular contacts in an openable and closable sliding manner; a DC power supply 10 for providing power for electrolyzing water is disposed on the outer side of the rotating inner drum, and the two output ends of the DC power supply are respectively electrically connected to the two brush contacts.

[0025] The rotating inner cylinder is a cylindrical structure. Two annular contacts are fixedly mounted on the outer wall of the rotating inner cylinder from top to bottom. The two annular contacts are insulated from each other and electrically connected to the two electrodes via wire 13 and wire 2 14, respectively. Two brush contacts are fixedly mounted on the upper end of the rotating rod from top to bottom. The two brush contacts are insulated from each other and can swing with the rotation of the rotating rod, thereby achieving an openable and sliding electrical connection with the two annular contacts. A torsion lever 15 is provided at the lower end of the rotating rod for driving the rotating rod to rotate. A return spring 16 is provided between the rotating rod and the fixed housing for driving the rotating rod to rotate and reset. A drive motor 17 is provided on the outside of the fixed housing. The output end of the drive motor is connected to the torsion lever via a pull rope 18.

[0026] The DC power supply utilizes an AC220V / DC24V power module. The two output terminals of the DC power supply are electrically connected to the two brush contacts via wire 19 and wire 20, respectively. The DC power supply input is connected to a 220V AC voltage, while the output terminal provides a safe 24V DC voltage. A current sensor 22 is also provided on wire 1 or wire 2.

[0027] like Figure 3 As shown, electrode one includes a conductive ring one 301 and a plurality of electrolytic fins one 302, and electrode two includes a conductive ring two 401 and a plurality of electrolytic fins two 402. The conductive ring two is coaxially sleeved in the middle of the conductive ring one. The two electrodes are connected by an insulating bolt 11.

Each electrolytic fin one is radially arranged on the inner wall of the conductive ring one, and each electrolytic fin two is radially arranged on the outer wall of the conductive ring two, and each electrolytic fin one is staggered with each electrolytic fin two.

[0028] When washing clothes, the return spring pushes the torsion lever and the rotating rod to rotate. At this time, the two brush contacts at the upper end of the rotating rod slide into contact with the two annular contacts respectively. When the water level in the barrel rises to the contact electrode, the current starts from the DC power supply and passes through brush contact 1, annular contact 1, electrode 1, washing water, electrode 2, annular contact 2, brush contact 2 and then returns to the DC power supply to form a loop. At the same time, the two electrodes electrolyze the washing water. During the washing process, the washing water rotates and flows, bringing the acid and alkaline substances produced by electrolysis into the rotating inner drum, thereby washing and sterilizing the clothes. In addition, since the current increases with the increase of the concentration of laundry detergent in the water during electrolysis, when rinsing is completed, the current detected by the current sensor can also be used to judge the content of laundry detergent in the water, and then to infer whether the clothes are rinsed clean.

[0029] The technical solution of the present invention is not limited to the limitations of the above specific embodiments. Without departing from the scope and spirit of the described embodiments, many modifications and changes are obvious to those of ordinary skill in the art. Any technical transformation made within the spirit and principle of the present invention falls within the protection scope of the present invention.
