Detailed Description

It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.

In the description of the present application, the "up," "down," "bottom" orientation or positional relationship is based on the orientation or positional relationship shown in fig. 9, it being understood that such orientation terms are merely for convenience in describing the present application and for simplicity in description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be considered limiting of the present application.

The length direction of the electrolysis device is consistent with the length direction of the first supporting part and the second supporting part, and the thickness direction of the electrolysis device is consistent with the thickness direction of the first supporting part and the second supporting part.

In one aspect of the present embodiment, an electrolysis apparatus 10 is provided, referring to fig. 1 and 2, the electrolysis apparatus 10 includes an electrolysis cathode 11 and an electrolysis anode 12; the electrolytic cathode 11 includes a first support 110 and at least one first comb tooth 111 extending from one side of the first support 110 to a direction away from the first support 110, and the first comb teeth 111 are arranged at intervals along a length direction of the first support 110, that is, the first comb teeth 111 are spaced from each other. Referring to fig. 3, the first comb teeth 111 include first supporting teeth 1111 and second supporting teeth 1112, and the first supporting teeth 1111 and the second supporting teeth 1112 are spaced apart from each other in a thickness direction of the first supporting portion 110, that is, the first comb teeth 111 are layered in the thickness direction of the first supporting portion 110.

The electrolysis anode 12 comprises a second support part 120 and at least one second comb tooth 121 extending from one side of the second support part 120 to a direction far away from the second support part 120, wherein the second comb teeth 121 are arranged at intervals along the length direction of the second support part 120; referring to fig. 4, the second comb teeth 121 include third teeth 1211 and fourth teeth 1212, and the third teeth 1211 and the fourth teeth 1212 are spaced apart from each other in the thickness direction of the second support portion 120, that is, the second comb teeth 121 are layered in the thickness direction of the second support portion 120.

The first comb teeth 111 and the second comb teeth 121 are alternately arranged along the length direction of the first support part 110 or the second support part 120, i.e., the first comb teeth 111 and the second comb teeth 121 are in an interdigital structure. It will be appreciated that the electrolytic cathode 11 and the electrolytic anode 12 are spaced apart from each other, i.e. no contact is made at any location in both the electrolytic cathode 11 and the electrolytic anode 12, so that proper operation of the electrolysis apparatus 10 is ensured.

The electrolysis device 10 of the embodiment of the present application, in a first aspect, for example, the electrolysis device 10 is applied to a clothes treatment apparatus, during washing clothes, lint on the clothes is mixed into water due to the first comb teeth 111 and the first comb teeth

The gaps among the second comb teeth 121, the gaps between the first teeth 1111 and the second teeth 1112, and the gaps between the third teeth 1211 and the fourth teeth 1212 are all long and narrow gaps through which lint can easily pass, that is, the lint is not easily blocked on the electrolysis apparatus 10, and the service life of the electrolysis apparatus 10 can be prolonged

In the second aspect, the first comb teeth 111 and the second comb teeth 121 are of an interdigital structure, that is, the electrolysis cathode 11 and the electrolysis anode 12 are arranged in a staggered manner in a plane perpendicular to the thickness direction of the electrolysis apparatus 10, that is, there is no overlapping portion between the electrolysis cathode 11 and the electrolysis anode 12 in the plane, when the electrolysis apparatus 10 is subjected to a force along the thickness direction of the electrolysis apparatus 10, even if the electrolysis cathode 11 or the electrolysis anode 12 is displaced by an external force, the electrolysis cathode 11 and the electrolysis anode 12 are not in contact with each other, so that the short circuit between the electrolysis cathode 11 and the electrolysis anode 12 can be effectively prevented, and therefore, the short circuit problem in the thickness direction can be reduced or not considered in the design of the electrolysis apparatus 10, and the design flexibility of the electrolysis apparatus 10 can be improved.

In the third aspect, since the first comb teeth 111 and the second comb teeth 121 are designed to have a layered structure, the working surface areas of the electrolysis cathode 11 and the electrolysis anode 12 can be increased, and therefore, under the condition that the working surface areas of the electrolysis device 10 for electrolysis are the same, the electrolysis device 10 of the embodiment of the present application occupies a smaller space in a plane perpendicular to the thickness direction, so that the structure of the electrolysis device 10 can be more compact, the miniaturization design of the electrolysis device 10 is facilitated, and the electrolysis device can be installed in a narrow space.

In the clothes treatment equipment, the service life of the electrolysis device needs to be matched with the design service life of the clothes treatment equipment, and if the service life of the electrolysis device is greatly smaller than the design service life of the clothes treatment equipment, the clothes treatment equipment can be scrapped in advance, and the benefit of consumers is damaged. The electrolytic device 10 in the embodiment of the application can better ensure that impurities such as catkins and the like cannot block the electrolytic cathode 11 and the electrolytic anode 12, and the service life of the electrolytic device 10 can be used to reach the design service life of the clothes treatment equipment.

It should be noted that, part of the first comb teeth 111 may be in a layered structure, and the other part of the first comb teeth 111 is not layered; it is also possible that all first comb teeth 111 are layered, i.e. each first comb tooth 111 comprises a first tooth 1111 and a second tooth 1112. Similarly, part of the second comb teeth 121 may be in a layered structure, and the other part of the second comb teeth 121 is not layered; it is also possible that all the second comb teeth 121 are layered, i.e. each second comb tooth 121 comprises a third tooth 1211 and a fourth tooth 1212.

In the embodiment of the present application, each first comb tooth 111 includes a first tooth 1111 and a second tooth 1112, and each second comb tooth 121 includes a third tooth 1211 and a fourth tooth 1212. This allows the electrolysis apparatus 10 to have a larger working surface area under the same conditions (i.e., in the case where the sizes of the electrolysis cathode 11 and the electrolysis anode 12 are the same, the number of the first comb teeth 111 is the same, and the number of the second comb teeth 121 is the same).

The specific structural form of the first teeth 1111 and the second teeth 1112 is not limited, and the first teeth 1111 and the second teeth 1112 can be in the form of a sheet, a column, a strip and the like; similarly, the specific structural forms of the third tooth 1211 and the fourth tooth 1212 are not limited, and may be in the form of a sheet, a column, a strip, and the like.

In the embodiment of the present application, referring to fig. 2, the first comb teeth 111 have substantially the same structure as the second comb teeth 121, the first comb teeth 111 are substantially parallel to the second comb teeth 121, and the first supporting portion 110 is substantially parallel to the second supporting portion 120, so that the electrolysis apparatus 10 has a more compact structure and a neat and beautiful appearance.

The first comb teeth 111 and the second comb teeth 121 may be completely flush with each other or slightly offset from each other in the thickness direction of the electrolyzer 10.

In the embodiment of the present application, the first comb teeth 111 and the second comb teeth 121 are completely flush with each other in the thickness direction of the electrolytic apparatus 10, specifically, referring to fig. 6 and 12, two opposite sides of the first support portion 110 and the first comb teeth 111 along the thickness direction of the electrolytic cathode 11 are flush with each other, that is, one side of the first support portion 110 and one side of the first comb teeth 111 are located in the same plane or curved surface, the other side of the first support portion 110 and the other side of the first comb teeth 111 are located in the same plane or curved surface, and the first support portion 110 and the first comb teeth 111 have the same thickness, so that the first support portion 110 and the first comb teeth 111 have a larger working surface area under the condition that the external dimension of the electrolytic cathode 11 is fixed.

Similarly, the two opposite sides of the second support part 120 and the second comb teeth 121 in the thickness direction of the electrolytic cathode 11 are flush, that is, one side of the second support part 120 and one side of the second comb teeth 121 are located in the same plane or curved surface, the other side of the second support part 120 and the other side of the second comb teeth 121 are located in the same plane or curved surface, and the second support part 120 and the second comb teeth 121 have the same thickness, so that the second support part 120 and the second comb teeth 121 have a larger working surface area under the condition that the external dimension of the electrolytic anode 12 is constant.

In an embodiment, referring to fig. 3, the first comb teeth 111 further includes a first connection portion 1113, and the first connection portion 1113 is connected between the first tooth 1111 and the second tooth 1112, that is, one end of the first connection portion 1113 is connected to the first tooth 1111, and the other end of the first connection portion 1113 is connected to the second tooth 1112. When the electrolytic cathode 11 is under the action of external force along the thickness direction of the electrolytic device 10, the first connection part 1113 is supported between the first teeth 1111 and the second teeth 1112, so that the structural strength of the first teeth 1111 and the second teeth 1112 can be enhanced, and the first teeth 1111 and the second teeth 1112 cannot collide and vibrate; further, the first connecting portion 1113 connects the first teeth 1111 and the second teeth 1112 to each other as a rigid unit, and can prevent the first teeth 1111 and the second teeth 1112 from swinging in the longitudinal direction of the first support portion 110 to some extent. Preferably, the first connection part 1113 does not exceed the outer contour range of the first teeth 1111 and the second teeth 1112, otherwise the first connection part 1113 may affect the external dimension of the electrolytic cathode 11.

Further, the first connection portion 1113 is connected between an end of the first tooth 1111 away from the first support portion 110 and an end of the second tooth 1112 away from the first support portion 110. This provides a greater degree of structural strength and prevents collision between the first tooth 1111 and the second tooth 1112.

Referring to fig. 4, the second comb teeth 121 include second connecting portions 1213, and the second connecting portions 1213 are connected between the third teeth 1211 and the fourth teeth 1212. That is, one end of the second connecting portion 1213 is connected to the third prong 1211, and the other end of the second connecting portion 1213 is connected to the fourth prong 1212. When the electrolysis anode 12 is under the action of external force along the thickness direction of the electrolysis device 10, the second connecting portion 1213 is supported between the third teeth 1211 and the fourth teeth 1212, so that the structural strength of the third teeth 1211 and the fourth teeth 1212 can be enhanced, and the third teeth 1211 and the fourth teeth 1212 do not collide and vibrate. The second connecting portion 1213 connects the third tooth 1211 and the fourth tooth 1212 to each other as a rigid unit, and also prevents the third tooth 1211 and the fourth tooth 1212 from swinging in the longitudinal direction of the second support portion 120 to some extent. Preferably, the second connecting portion 1213 does not exceed the outer contour of the third tooth 1211 and the fourth tooth 1212, otherwise the second connecting portion 1213 may affect the external dimension of the anode 12.

Further, the second connecting portion 1213 is connected between an end of the third prong 1211 remote from the first support 110 and an end of the fourth prong 1212 remote from the first support 110. This provides a greater degree of structural strength and prevents collisions between the third prong 1211 and the fourth prong 1212.

The inter-polar distance between the electrolysis cathode 11 and the electrolysis anode 12 needs to be kept in a proper range, if the inter-polar distance is larger, the energy consumption is increased, the effective working area of the electrodes in the same size space is reduced, the generation amount of hydroxyl radicals (& OH) generated by the electrolysis of water is also reduced, and the electrolysis efficiency of the electrolysis device 10 is reduced. If the electrode spacing is too small, the electrode may break down, and the release of a large amount of bubbles during electrolysis may be inhibited, and bubbles may be collected on the surface of the electrode (the electrolysis cathode 11 and/or the electrolysis anode 12), and the surface of the electrode to which the bubbles are attached may not be in contact with water, so that the effective electrolysis working area of the electrode may be rapidly reduced, the efficiency may be greatly lowered, and the generation of. OH may be inhibited. Therefore, it is advantageous to maintain the electrode spacing in a proper range to increase the amount of OH generated, and in the present embodiment, the electrode spacing between the electrolytic cathode 11 and the electrolytic anode 12 is 0.5mm to 20mm (millimeter).

The above-mentioned inter-polar distance is the minimum distance between any two positions between the electrolytic anode 12 and the electrolytic cathode 11. Specifically, in the embodiment of the present application, please refer to fig. 5, the pole pitches include a first pole pitch d1, a second pole pitch d2, and a third pole pitch d3, wherein a first pole pitch d1 exists between adjacent first comb teeth 111 and second comb teeth 121, a second pole pitch d2 exists between an end of the first comb teeth 111 and the second support 120, and a third pole pitch d3 exists between an end of the second comb teeth 121 and the first support 110. The first pole pitch d1, the second pole pitch d2 and the third pole pitch d3 are all between 0.5mm and 20 mm.

The first pole pitch d1, the second pole pitch d2, and the third pole pitch d3 may be equal or unequal.

The power supply needs insulation protection to prevent short circuit caused by water wetting, so the power supply is located outside the outer cylinder 30, and water in the outer cylinder 30 cannot leak to the outside of the outer cylinder 30. Therefore, in an embodiment of the present invention, an avoiding hole 30a (see fig. 14) is formed in the outer cylinder 30, and a part of the main body 22 is sealingly inserted into the avoiding hole 30a to perform a waterproof function.

Further, referring to fig. 2 and 15, the main body 22 includes a first mounting plate 221, a second mounting plate 222, and an elastic body 223. Referring to fig. 14, the elastic body 223 is disposed in the avoiding hole 30a, the first mounting plate 221 is disposed on the inner side of the outer cylinder 30, the second mounting plate 222 is disposed on the outer side of the outer cylinder 30, and the elastic body 223 is sandwiched between the first mounting plate 221 and the second mounting plate 222. The first through hole 20a, the second through hole 20b, and the connection hole 20c all penetrate the first mounting plate 221, the second mounting plate 222, and the elastic body 223.

The elastic body 223 can be deformed under pressure by tightening the first mounting plate 221 and the second mounting plate 222 with the connector 24, and the elastic body 223 can be reliably brought into sealing contact with the inner wall of the escape hole 30a in the circumferential direction after the deformation, and further, the inner wall of the first through-hole 20a can be brought into sealing contact with the cathode conductive connection body 13, the second through-hole 20b can be brought into sealing contact with the anode conductive connection body 14, and the connector 24 can be brought into sealing contact with the inner wall of the connection hole 20 c.

During assembly, the elastic body 223 is placed into the avoidance hole 30a from the outer side of the outer cylinder 30, and the elastic body 223 is pushed inwards until the abutting surface 223a abuts against the outer surface of the outer cylinder 30, so that the elastic body 223 can be positioned quickly and accurately.

In order to protect the end of the elastic body 223, referring to fig. 2 and 15, the second mounting plate 222 is formed with a concave area 222a adapted to the shape of the end of the elastic body 223, and the second mounting plate 222 covers the end of the elastic body 223.

As for the whole electrolytic device 10, the electrolytic device 10 at least comprises two supporting force bearing points, one is the support formed by the connection part of the mounting device 20 and the outer cylinder 30 to the electrolytic device 10, and the other is the support formed by the supporting seat 32 to the electrolytic device 10, and the two supporting points can improve the force bearing condition of the electrolytic device 10. Specifically, if only the connection between the mounting device and the outer cylinder supports the electrolyzer, the length of the electrolyzer 10 is relatively long and only one support point is provided, the stress mode of the electrolyzer 10 is cantilever stress, and under the impact of water flow, on one hand, the electrolyzer 10 is subjected to a large shearing force, which easily causes structural damage to the electrolyzer 10, and on the other hand, the electrolyzer 10 is unstable and easily shakes.

Further, in order to prevent the lateral swing of the electrolysis apparatus 10 under the impact of the water current, the support base 32 is configured to be able to restrict the lateral swing of the electrolysis apparatus 10.
