[0038] In this embodiment, the outer barrel 1 and the inner barrel 2 are both made of engineering plastic. Rectangular holes are opened on both sides of the outer barrel 1 along the barrel axis, and a number of screw holes 10 are opened along the extension of the rectangular holes. A rectangular metal sheet with a side length greater than the rectangular hole of the outer barrel 1 is pressed to form a concave surface with the same length and width as the rectangular hole, i.e. a metal sheet 3 with a concave surface is obtained. The metal sheet 3 with a concave surface can be embedded in the opening of the outer barrel 1. Figure 1 And Figure 3 The outer edge of the concave surface of the metal sheet is embedded with a sealing strip 8, and the outermost edge of the metal sheet 3 with a concave surface is also provided with screw holes 10 corresponding to the positions of the screw holes 10 of the outer barrel 1, as shown in Figure 4 The screw 4 is inserted through the metal sheet 3 with a concave surface, then through the rubber washer 9, the wall of the outer barrel 1 and another rubber washer 9, and finally connected with the nut 5, as shown in Figure 2 The sealing strip 8 and the rubber washer 9 can make the outer barrel 1 leakproof.

[0039] In this embodiment, the material of the inner barrel 2 is changed from stainless steel to engineering plastic. Rivet holes are opened along the axis of the inner barrel 2 and basically cover the entire side surface, and finally metal rivets (double-sided rivets) 6 are punched. The inner barrel 2 is also provided with a drain hole 12.

[0040] The distance between the outer barrel 1 and the inner barrel 2 is less than or equal to 10 mm; the voltage of the power supply 7 is greater than or equal to 200 V.

[0041] The two metal sheets 3 with concave surfaces are connected to the positive and negative poles of the built-in DC power supply of the washing machine. At this time, the metal sheets connected to the positive and negative poles of the power supply are embedded in the opening of the outer barrel and sealed with screws, forming an equivalent electrolytic cell. Example 2

[0042] As another embodiment of the present application, in this embodiment, a metal strip 11 is provided between the axial metal rivets (double-sided rivets) 6 on the inner barrel 2, and the metal rivets 6 pass through the through holes of the metal strip 11. The inner barrel 2 is provided with a drain hole 12, as shown in Figure 5 The advantages of this arrangement are: setting the metal strip can increase the contact area between the clothes and the induction metal, and improve the oxidation-reduction effect.

[0043] During operation, after the washing machine starts, the concave metal plate embedded in the outer drum connects to the DC power supply. The metal plate connected to the positive terminal becomes positively charged, inducing a negative charge on the rivets on the nearby inner drum. The metal plate connected to the negative terminal becomes negatively charged, inducing a positive charge on the rivets on the nearby inner drum. As the inner drum, carrying water and clothes, rotates, the positive and negative charges on the rivets are cyclically transferred to the clothes, cyclically triggering oxidation-reduction reactions on the clothes—anodic oxidation and cathodic reduction. Ultimately, the continuous cycle of electro-oxidation-reduction reactions degrades the dirt on the clothes, achieving the effect of cleaning.

[0044] After a period of use, the positive and negative terminals of the power supply can be reversed to remove the scale on the metal plates, thus increasing the service life of the chemical-free washing machine of this invention.

[0045] Experiments were conducted using the chemical-free washing machine of this invention to clean standard carbon black-stained cloth. Figure 6 In the diagram, we can clearly see a significant difference in washing results. The chemical-free washing machine of this invention can effectively remove carbon black from standard carbon black-stained cloth (as shown on the right side of the diagram). If the chemical-free washing machine of this invention is not powered on, it cannot remove the carbon black from the standard carbon black-stained cloth.

[0046] The working principle of the chemical-free washing machine of this invention is as follows: Figure 7 As shown, one end of the metal rivet near the positively charged metal sheet 3 at the anode is induced to be negatively charged, while the other end of the metal rivet is positively charged.

[0047] Near the anode, the positively charged metal rivet directly contacts the clothing, causing an oxidation reaction that can oxidize oil stains, sweat stains, proteins, amino acids, and other substances on the clothing.

[0048] When a positively charged metal rivet comes into direct contact with clothing, an oxidation reaction occurs, which in turn oxidizes the carbon black on the clothing. The carbon black on the clothing then loses electrons at the anode, reacting to form carbon dioxide.

[0049] The oxidation reaction in the washing machine drum water is mainly the direct contact reaction mentioned above. Indirect reactions also occur in the aqueous solution, including electrolysis. The reaction equation is as follows:

[0050]

[0051] The generated H + It can acidically hydrolyze proteins and amino acids in oil stains, sweat stains, etc. on clothing.

[0052] Carbon black on clothing can react with oxygen at the anode to produce carbon dioxide.

[0053] The metal rivet end of the metal sheet 3 close to the cathode is positively charged, and the other end of the metal rivet is negatively charged.

[0054] The metal rivet end of the metal sheet 3 close to the cathode is positively charged, and the other end of the metal rivet is negatively charged.

[0055] The metal rivet end of the metal sheet 3 close to the cathode is positively charged, and the other end of the metal rivet is negatively charged.

[0056] The metal rivet end of the metal sheet 3 close to the cathode is positively charged, and the other end of the metal rivet is negatively charged.

[0057] The metal rivet end of the metal sheet 3 close to the cathode is positively charged, and the other end of the metal rivet is negatively charged.

[0058]

[0059] The generated OH - The oil stains, sweat stains and other proteins and amino acids on the clothes can be subjected to alkaline hydrolysis.

[0060] The carbon black on the clothes can react with hydrogen gas at the cathode to generate methane.

[0061] The experimental data obtained when the washing machine is simulated is shown in Table 1. Figure 8 In the drum, the two large graphite rods in the middle and the two small titanium electrodes on the sides, when the induced voltage between the two graphite rods is 90V, the actual measured voltage between the two titanium electrodes is 309V.
