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. 10, 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.

In one aspect of the embodiments of the present disclosure, referring to fig. 1 and 2, an electrolysis apparatus 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 the first support 110 in a direction away from the first support 110, the first comb tooth 111 being arranged at intervals along a longitudinal direction of the first support 110; the electrolysis anode 12 comprises a second support part 120 and at least one second comb tooth 121 extending from 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; 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 is ensured.

In the electrolysis device of the embodiment of the application, the first comb teeth 111 and the second comb teeth 121 are in an interdigital structure, so that on one hand, the electrolysis cathode 11 and the electrolysis anode 12 are ensured to have larger working surface areas, and the electrolysis efficiency of the electrolysis device is improved, on the other hand, the electrolysis cathode 11 and the electrolysis anode 12 only need to occupy smaller space, and the electrolysis device can be compact in structure; on the other hand, taking the application of the electrolysis device to the clothes treatment apparatus as an example, during the clothes washing process, the lint on the clothes is mixed into the water, and since the gap between the first comb teeth 111 and the second comb teeth 121 is a long and narrow gap, the lint can easily pass through the long and narrow gap, that is, the lint is not easily blocked on the electrolysis device, and the service life of the electrolysis device can be prolonged.

It should be noted that, in the clothes treatment apparatus, the life of the electrolysis device needs to match the design service life of the clothes treatment apparatus, and if the service life of the electrolysis device is substantially less than the design service life of the clothes treatment apparatus, the clothes treatment apparatus may be scrapped in advance, and the consumer benefit may be damaged. The electrolytic device in the embodiment of the application can better ensure that impurities such as catkins and the like cannot block the electrolytic cathode and the electrolytic anode, and the service life of the electrolytic device can be prolonged to reach the design service life of the clothes treatment equipment.

The first comb teeth 111 and the second comb teeth 121 may be arranged in a coplanar manner, or may be slightly offset by a predetermined distance in the thickness direction of the electrolyzer.

In the embodiment of the present application, the first comb teeth 111 and the second comb teeth 121 are disposed in a coplanar manner, and the electrolysis cathode 11 and the electrolysis anode 12 are disposed in the same plane or curved surface, that is, the first support part 110, the first comb teeth 111, the second support part 120, and the second comb teeth 121 are disposed in a coplanar manner, that is, the electrolysis cathode 11 and the electrolysis anode 12 are disposed in a staggered manner, that is, in the plane or curved surface, no overlapping portion exists between the electrolysis cathode 11 and the electrolysis anode 12, and when the electrolysis apparatus is subjected to an external force substantially perpendicular to the plane or curved surface, since no overlapping portion exists between the electrolysis cathode 11 and the electrolysis anode 12, even if the electrolysis cathode 11 or the electrolysis anode 12 is displaced by the external force, the electrolysis cathode 11 and the electrolysis anode 12 do not contact with each other, and therefore, the contact short circuit between the electrolysis cathode 11 and the electrolysis anode 12. By such design, the thickness of the electrolytic cathode 11 and the electrolytic anode 12 can be designed to be very thin, for example, the thickness can be 1-4mm, which is beneficial to the light and thin design of the electrolysis device, so that the electrolysis device can be installed in a narrow space, for example, between the inner drum and the outer drum 30 of the clothes treatment equipment.

The specific structural form of the first comb teeth 111 is not limited, and the first comb teeth can be in the shape of a sheet, a column, a strip and the like; similarly, the specific structural form of the second comb teeth 121 is not limited, and may be in the form of a sheet, a column, a strip, or the like.

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 OH generated by electrolyzed water is also reduced, and the electrolysis efficiency of the electrolysis device 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 (electrolytic cathode and/or electrolytic anode), and the surface of the electrode to which the bubbles are attached may not be in contact with water, so that the effective electrolytic working area of the electrode may be rapidly reduced, and the efficiency may be significantly reduced, which is disadvantageous for the generation of. OH. Therefore, it is advantageous to maintain the electrode distance in a suitable range to increase the amount of OH generated, and in the present embodiment, the electrode distance between the electrolytic cathode 11 and the electrolytic anode 12 is 0.5mm to 20mm (millimeter), and in the present embodiment, the electrode distance between the electrolytic cathode 11 and the electrolytic anode 12 is preferably 1.5mm to 5 mm.

The first pole pitch d1, the second pole pitch d2 and the third pole pitch d3 are all between 0.5mm and 10 mm. Preferably, the first pole pitch d1 between the adjacent first comb teeth 111 and the second comb teeth 121 is 1.5-5 mm, and the value is within the range, so that the electrolytic effect is better.

Further, in an embodiment, the first pole pitch d1, the second pole pitch d2 and the third pole pitch d3 are equal, for example, after a test experiment, the values of the first pole pitch d1, the second pole pitch d2 and the third pole pitch d3 are all the optimal values of the test experiment. Thus, the efficiency of the electrolysis apparatus can be made higher.
