The installation process and principle of the electrolysis device 10 will be explained by taking the application of the electrolysis device 10 to the clothes treating apparatus as an example.

Referring to fig. 4, the clothes treating apparatus includes an inner drum (not shown), an outer drum 20 and the electrolysis device 10 of the embodiment of the present application, wherein the inner drum is rotatably disposed in the outer drum 20, and referring to fig. 6 and 8, the outer drum 20 is formed with a mounting opening 21a and a clamping portion 23; the electrode 11 is located between the outer barrel 20 and the inner barrel, and referring to fig. 13, the locking surface 122a abuts against the clamping portion 23, and the sealing structure 12a abuts against the periphery of the mounting opening 21a in a sealing manner.

In the working process of the clothes treatment equipment provided by the embodiment of the application, the electrode 11 can generate hydroxyl radicals (OH) with strong oxidation activity, the OH has a very high oxidation potential (2.80eV), the oxidation capacity is very strong, the quick chain reaction can be carried out on the OH and most of organic pollutants, the OH can be sterilized and disinfected at a low temperature, the clothes are not damaged, part of the OH reacts with chlorine water in tap water to generate active chlorine, and the active chlorine can exist for a long time and has a long-term bacteriostasis effect; the electrode 11 generates a large amount of hydroxyl free radicals to oxidize and destroy chromophoric groups of dye molecules dissociating into water in the colored clothes in the washing process so as to decolor the dye, prevent the dissociative dye from being stained into light-colored clothes to cause color cross, and continuously react to decompose the dye molecules into harmless carbon dioxide, water and inorganic salt. Meanwhile, the electrode 11 can generate a large amount of hydrogen microbubbles, the diameter of the microbubbles is very small and is usually smaller than 50um, so that the microbubbles can well enter the fiber of the clothes in the washing process, and the microbubbles are continuously circularly flushed through the actions of microbubble explosion and adsorption floating to assist the detergent to thoroughly remove dirt such as sebum, grease and tiny dust accumulated in the fiber of the clothes, so that the cleaning effect can be improved.

It should be noted that the laundry treatment apparatus in the embodiment of the present application may be a washing machine, a spin dryer, or other types of apparatuses, and is not limited herein. It is understood that the washing machine may be a pulsator washing machine, a drum washing machine, or other types of washing machines.

During assembly, the screwing body 121 is rotated, so that the locking surface 122a abuts against the clamping portion 23, the locking surface 122a is located on one side, facing the inner cylinder, of the clamping portion 23, the sealing structure 12a abuts against the periphery of the mounting opening 21a while the locking surface 122a abuts against the clamping portion 23, part of the structure of the mounting device 20 is tightly clamped between the clamping portion 23 and the structure of the periphery of the mounting opening 21a, the mounting device 20 is prevented from moving along the inner and outer directions of the outer barrel 20, the sealing structure 12a firmly abuts against the periphery of the mounting opening 21a, the mounting opening 21a is sealed, pretightening force along the inner and outer directions of the outer barrel 20 is not required to be provided through screws in the prior art, the problem of sealing failure caused by loosening of the screws in the prior art can be avoided, and the sealing reliability is effectively improved; furthermore, in the process that the clamping portion 23 abuts against the locking surface 122a, the pretightening force formed by the clamping portion 23 on the screwing body 121 is approximately uniform along the circumferential direction of the mounting opening 21a, so that the sealing structure 12a can generate approximately uniform elastic deformation along the circumferential direction of the mounting opening 21a, and the problem of untight sealing caused by the uneven stress is avoided. In the prior art, in the process of installing the screws, the elastic deformation of the sealing position where the screw is installed first may become large, the elastic deformation of the sealing position where the screw is installed later is small, the elastic deformation is uneven, and the water leakage caused by poor sealing is caused.

The specific structural shape of the electrode 11 is not limited as long as water can be electrolyzed when energized.

The electrode 11 can be directly connected to the screw body 121 or indirectly connected to the screw body 121 through other structures. In the embodiment of the present application, the electrode 11 is indirectly connected to the screw body 121 through another structure. Specifically, referring to fig. 13, the electrolytic device 10 includes a conductive connecting body 13 electrically connected to the electrode 11, wherein the conductive connecting body 13 hermetically penetrates from a first side of the screw body 121 to a second side opposite to the first side, that is, the conductive connecting body 13 penetrates from inside the outer tub 20 to outside the outer tub 20 so as to be electrically connected to a power source. In the embodiments of the present application, the first side and the second side refer to directions.

The conductive connecting body 13 can be hermetically screwed through the screw body 121 in various ways, for example, after the screw body 121 is molded, a through hole is formed in the screw body 121, the conductive connecting body 13 is inserted into the through hole, then the conductive connecting body 13 and the screw body 121 are bonded by using an adhesive, and the adhesive is hermetically filled between the conductive connecting body 13 and the inner wall of the through hole, so as to implement a sealed connection; for another example, the screw body 121 is injection molded around the conductive connecting body 13, and after the screw body 121 is molded, the screw body 121 and the conductive connecting body 13 are combined together without connecting through other structures.

The screw body 121 may be directly in sealing abutment with the tub 20, that is, the screw body 121 is partially structured as the sealing structure 12a described above. In the embodiment of the present application, please refer to fig. 2, the mounting device 12 includes a sealing ring 123, and the sealing ring 123 is the sealing structure 12a described above. The screw body 121 is formed with a mounting surface 121a facing the first side, the sealing ring 123 is disposed on the mounting surface 121a, the mounting surface 121a supports the sealing ring 123, the sealing ring 123 is sandwiched between the mounting surface 121a and the outer tub 20, and the sealing performance between the mounting device 12 and the outer tub 20 is improved by elastic deformation of the sealing ring 123.

The surface of the sealing structure 12a facing the first side may be a plane, a curved surface, a combination of a plane and a curved surface, and the like, and is not limited herein. For example, in one embodiment, the sealing ring 123 has a flat structure, and the surface of the sealing ring 123 facing the first side is a plane, that is, the surface of the sealing structure 12a facing the first side is a plane, so that the contact area between the sealing ring 123 and the tub 20 can be increased, and the reliability of the sealing abutment between the sealing ring 123 and the tub 20 can be improved.

In order to facilitate the positioning of the sealing ring 123 and prevent the sealing ring 123 from separating from the mounting surface 121a, in an embodiment, please refer to fig. 2 and fig. 3, a boss 1211 is formed at an end of the screw body 121, the mounting surface 121a is disposed around the boss 1211, an inwardly recessed annular groove 121b is formed around the boss 1211, and the sealing ring 123 is inserted into the annular groove 121b along a radial inner side, that is, one side of the annular groove 121b is flush with the mounting surface 121a, so that the inner structure of the sealing ring 123 can be inserted into the annular groove 121 b. The groove 121b prevents the seal ring 123 from being disengaged from the screw body 121, and reduces the possibility that the seal ring 123 will rotate relative to the screw body 121 due to the friction of the outer tub 20 during the rotation of the screw body 121.

In an embodiment, referring to fig. 3, an accommodating space 121c is formed inside the screw body 121, one end of the screw body 121 on the first side is closed, a second side of the screw body 121 opposite to the first side is open, and a part of the conductive connecting body 13 is located in the accommodating space 121 c. Thus, the accommodating space 121c protects the conductive connecting body 13 and prevents other parts from scratching the conductive connecting body 13 after assembly.

It should be noted that the screw body 121 is substantially barrel-shaped, so that the screw body 121 can rotate in the escape opening. The cross-sectional shape of the screw body 121 in parallel to the rotational direction is not limited, and may be a circle, a polygon, a non-circular shape formed by a curve, a shape formed by a straight line and a curve, or the like. In the present embodiment, the cross-sectional shape of the screw body 121 parallel to the rotation direction is substantially circular, so as to reduce the space required for the screw body 121 during the screwing process.

The specific structure of the locking portion 122 is not limited as long as it can form a locking surface 122a extending along the circumferential direction of the screw body 121, for example, the locking portion 122 may be a rib protruding from the circumferential surface of the screw body 121, or may be a step structure formed on the circumferential surface of the screw body 121. The locking portion 122 and the screw body 121 may be formed integrally or may be formed separately and fastened together.

For example, in the embodiment of the present application, please refer to fig. 1 and fig. 2, the locking portion 122 is integrally formed with the screw body 121, a groove 121d is formed on the circumferential surface of the screw body 121, and a sidewall corresponding to the groove 121d is the locking surface 122a, so that the processing and the manufacturing are facilitated, and the production cost is reduced. During assembly, the clamping portion 23 is clamped into the groove 121d, that is, the clamping portion 23 has a general shape that can enter the groove 121 d.

In order to facilitate the locking surface 122a to smoothly abut against the clamping portion 23 during the rotation process, in an embodiment, referring to fig. 1, the locking surface 122a includes an inclined guiding sub-surface 122a ' and a locking sub-surface 122a ' arranged along the rotation direction, and the inclined guiding sub-surface 122a ' is located at an entrance of the locking surface 122 a. The entrance of the locking surface 122a refers to the end of the locking surface 122a that is first contacted with the clamping portion 23 during the rotation of the assembly lock. The inclined guide sub-surface 122a 'contacts with the clamping portion 23 first, so that the inclined guide sub-surface 122 a' can slide along the clamping portion 23 smoothly, the butt joint time of the locking surface 122a and the clamping portion 23 is shortened, the assembling time is saved, and the assembling difficulty is reduced. Furthermore, a certain installation space is formed between the clamping portion 23 and the structure around the installation opening 21a, a structure between the sealing ring 123 and the locking surface 122a forms a structure similar to a wedge, the inclined guide sub-surface 122a 'is similar to a wedge-shaped surface, during the rotation of the screwing body 121, the structure between the sealing ring 123 and the locking surface 122a is continuously wedged into the installation space, and the clamping portion 23 and the inclined guide sub-surface 122 a' are matched, so that the clamping portion 23 continuously pushes the screwing body 121 to move towards the outer barrel 20, and further the pre-tightening force between the outer barrel 20 and the installation device 12 is continuously increased, that is, the rotation of the screwing body 121 can be converted into the linear motion of the screwing body 121 towards the outer barrel 20, and during the assembly, an operator only needs to apply a small force to rotate the screwing body 121.

The locking sub-surface 122a ″ is located downstream of the inclined guiding sub-surface 122a 'in the locking direction, that is, during the locking of the locking surface 122a with the engaging portion 23, the engaging portion 23 contacts the inclined guiding sub-surface 122 a' first and then contacts the locking sub-surface 122a ″.

It will be appreciated that the slanted guide sub-surface 122a 'and the locking sub-surface 122a "may be adjacently disposed, i.e., the slanted guide sub-surface 122 a' and the locking sub-surface 122 a" are adjacently disposed in the rotational direction; the inclined guide sub-surface 122a 'and the locking sub-surface 122a ″ may be disposed at intervals, that is, a transitional connecting surface or the like is disposed between the inclined guide sub-surface 122 a' and the locking sub-surface 122a ″, which is not limited herein.

The locking sub-surface 122a ″ is used for being matched with the clamping portion 23 in a locking mode, and after the installation device 12 is installed in place, the clamping portion 23 is in locking contact with the locking sub-surface 122a ″. A certain pre-tightening force is formed between the locking sub-surface 122a ″ and the clamping portion 23, that is, the locking sub-surface 122a ″ applies an acting force to the clamping portion 23, the clamping portion 23 applies a reaction force to the locking sub-surface 122a ″, and the reaction force acts on the entire screwing body 121, so that the sealing ring 123 is sealed and abutted around the mounting opening 21 a.

In order to improve the locking reliability between the locking sub-surface 122a ″ and the catching portion 23, the reaction force of the catching portion 23 on the locking sub-surface 122a ″ cannot have a component force opposite to the locking rotation direction, for example, a component force toward the right in fig. 1, which would otherwise easily cause the screw body 121 to rotate reversely so that the locking sub-surface 122a ″ is disengaged from the catching portion 23. In the embodiment of the present application, the locking sub-surface 122a ″ is parallel to the rotation direction of the screw body 121, so that on one hand, the acting force and the reaction force between the locking sub-surface 122a ″ and the clamping portion 23 can be almost perpendicular to the rotation direction, and the locking reliability can be improved; on the other hand, during the locking rotation, the pre-tightening force between the clamping portion 23 and the locking sub-surface 122a ″ is not reduced, and the sealing reliability of the sealing ring 123 and the structure around the mounting opening 21a is not affected.

It will be appreciated that the locking sub-surface 122a "may also be a slightly inclined surface, inclined away from the entrance of the locking surface 122a, i.e. substantially opposite to the inclination of the inclined guide sub-surface 122 a'.

The number of the locking portions 122 may be configured according to actual use requirements, and may be one or more, for example. In the embodiment of the present application, the number of the locking portions 122 is two, and the two locking portions 122 are uniformly spaced along the circumferential direction of the screw body 121.

The laundry treating apparatus may vibrate during operation, which may cause the screw body 121 to rotate reversely, and further cause the screw body 121 to be loosened. In one embodiment, referring to fig. 1, the mounting device 12 includes a limiting portion 124, the limiting portion 124 protrudes from the circumferential surface of the screwing body 121, and the limiting portion 124 is connected to the outer barrel 20 to prevent the screwing body 121 from reversely rotating under the external effect.

The structure of the stopper 124 is not limited as long as it can be conveniently connected to the outer tub 20. In an embodiment, referring to fig. 1, the position-limiting portion 124 is a plate-shaped structure, the position-limiting portion 124 is formed with a first connection hole 124a, and the connection member 24 (see fig. 10) such as a screw or a bolt passes through the first connection hole 124a and is fastened to the outer tub 20. Since the connector 24 such as a screw or a bolt does not bear the preload of the seal ring 123 and the surrounding structure of the mounting opening 21a, even if the mounting state of the connector 24 does not affect the sealing performance of the mounting device 12, the connector 24 only needs to be able to limit the rotation of the screw body 121.

In one embodiment, referring to fig. 6 and 8, the outer tub 20 includes a tub body 21 and a flange 22, the mounting opening 21a is formed on the tub body 21, and the inner tub is located in the tub body 21; the flange 22 extends outwards from the periphery of the installation opening 21a on the outer side of the barrel body 21, one side of the flange 22 away from the installation opening 21a is opened, at least part of the structure of the installation device 12 is positioned in the flange 22, the clamping part 23 is arranged on the inner side surface of the flange 22, and the sealing structure 12a is in sealing contact with the periphery of the installation opening 21a on the outer side of the barrel body 21.

It can be understood that the clamping portion 23, the barrel body 21 and the flange 22 can be integrally formed, which is convenient for manufacturing and enhancing the structural strength of the clamping portion 23.

In order to avoid the above-mentioned position-limiting portion 124, in an embodiment, referring to fig. 6 and 8, a part of the structure of the flange 22 along the circumferential direction protrudes outwards to form a recessed portion 221 in the flange 22, and the position-limiting portion 124 is located in the recessed portion 221. The size of the recess 221 is such that: the stopper 124 can be disposed into the recess 221 from the opening of the flange 22, for example, the recess 221 extends to the end of the flange 22 away from the end of the tub body 21; and the limiting part 124 can rotate along with the screwing body 121 in the recess 221, and the limiting part 124 can be tightly connected with one side of the recess 221 close to the barrel body 21.

In one embodiment, a second connection hole 221a is formed on one side of the recessed portion 221 close to the tub body 21, and the second connection hole 221a may be a through hole or a blind hole; the connecting member 24 such as a bolt or a screw is inserted into the first connecting hole 124a and the second connecting hole 221a to fasten and connect the stopper portion 124 and the recess portion 221.

The various embodiments/implementations provided herein may be combined with each other without contradiction.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art.
