Description

Clothes treating apparatus Technical Field The invention relates to the technical field of clothes treatment equipment, and particularly provides clothes treatment equipment. Background With the development of social economy and the improvement of living standard, the washing machine becomes an indispensable household appliance in daily life of people. Taking a drum washing machine as an example, a fixed and non-rotating outer drum is arranged in a shell of the drum washing machine, the outer drum is used for containing washing water, the inner drum is rotatably arranged in the outer drum, and water permeable holes are formed in the inner drum and used for containing clothes and realizing washing by falling and beating the clothes in the rotating process. However, in the prior art, the outer barrel is typically made of plastic through an injection molding process. In order to facilitate demolding during injection molding, the outer cylinder is usually divided into two halves during design, and the outer cylinder is assembled into a whole through fasteners after the injection molding is completed. In order to prevent water leakage, a sealing element is arranged on the butt joint surface, the sealing element is usually a solid rubber O-shaped ring, and the sealing part has a larger diameter of about 55 cm and also has a convex heating cabin, so that the using length of the sealing element can reach 2 meters, more materials are consumed, and the cost of the sealing ring is higher. If the hollow rubber ring with lower cost is directly adopted for reducing the cost, the sealing reliability is reduced. Accordingly, there is a need in the art for a new laundry treatment apparatus to address the high cost of seals on existing laundry treatment cartridges. Disclosure of Invention The present invention aims to solve the above-mentioned technical problem, namely, the problem of high cost of the sealing member on the existing laundry treating drum. In a first aspect, the present invention provides a laundry treatment apparatus, the laundry treatment apparatus comprising a first abutting portion and a second abutting portion, a hollow sealing member being provided between the first abutting portion and the second abutting portion, a groove being provided on at least one of abutting surfaces of the first abutting portion and the second abutting portion, an outer diameter of the hollow sealing member being larger than an opening size of the groove, the hollow sealing member being subjected to compression deformation after the first abutting portion and the second abutting portion are connected, such that a portion is embedded into the groove to form a first protruding sealing portion, and another portion is formed to form a second protruding sealing portion, so as to seal a gap between the first abutting portion and the second abutting portion. Under the condition of adopting the technical scheme, because the external diameter of the hollow sealing member is larger than the opening size of the groove, when one of the first butt joint part and the second butt joint part is pressed on the hollow sealing member from top to bottom, the hollow sealing member can deform. A part of the deformed hollow sealing piece is embedded into the groove to form a first convex sealing part, and the other part of the deformed hollow sealing piece forms a second convex sealing part so as to seal a gap between the first abutting part and the second abutting part. The deformed hollow sealing piece forms a plurality of contact ring surfaces between the first butt joint part and the second butt joint part to form multi-stage sealing, so that the sealing effect is enhanced, the hollow sealing piece saves more raw materials, and the cost is lower. In an alternative aspect of the laundry treatment drum described above, the laundry treatment apparatus comprises a laundry treatment drum comprising a first and a second connected drum portion, a hollow seal being provided between the first and the second drum portion. A groove is formed in at least one of the abutting surfaces of the first cylinder body and the second cylinder body, and the outer diameter of the hollow sealing member is larger than the opening size of the groove. After the first cylinder body and the second cylinder body are connected, the hollow sealing piece is extruded and then deforms, so that one part of the hollow sealing piece is embedded into the groove to form a first protruding sealing part, and the other part of the hollow sealing piece forms a second protruding sealing part to seal a gap between the first cylinder body and the second cylinder body. In the case of adopting the above technical solution, since the outer diameter of the hollow seal is larger than the opening size of the groove, the hollow seal is deformed when one of the first cylinder portion and the second cylinder portion is pressed against the hollow seal from top to bottom. A part of the deformed hollow sea
