Jackets and washers for pipes

Abstract

The invention discloses a sheath for pipelines and a washing machine. The sheath (100) includes a sheath body (1) and a hoop segment (2), wherein the sheath body (1) is formed to It is in the shape of a continuous one-piece sleeve; the hoop section (2) protrudes from the sheath body (1), and the hoop section (2) includes multiple hoops that are hooped on the outer peripheral wall of the pipeline and distributed along the circumferential direction. petals (21). Compared with the existing circumferentially split sheath, the sheath of the present invention is formed in a circumferentially integrated form, and the pipe can have multiple hoop segments that can pass through multiple petals, and the multiple petals The radially outward elastic expansion of the part provides a pre-pressure to press against the outer peripheral wall of the pipe, so that the sheath and the pipe can be clamped and assembled. At the same time, the shape of the sheath is more complete and beautiful, and the roundness is better, which can make the assembly structure of the pipeline more stable.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a sheath for pipes and a washing machine. Background technique [0002] In the existing drum washing machine, the drain pipe usually adopts a corrugated pipe, and the drain pipe is installed on the shell of the box body of the rear tub assembly through a sheath. A common sheath is made of two semi-circular structures, see eg Figure 1 to Figure 6 As shown, the sheath acts between the drainpipe and the shell of the box body. Due to its structural design deficiency, there are many defects: 1. The lip of the sheath is prone to axial misalignment when it is assembled with the drainpipe Phenomenon, causing two semi-circular lip dislocations to be inserted into the drain pipe of the corrugated pipe, which will be damaged after long-term use; 2. In the design scheme where the sheath structure is spliced ​​with two semi-circular structures , due to a certain tolerance design, when th...

A common sheath is made of two semi-circular structures, see eg Figure 1 to Figure 6 As shown, the sheath acts between the drainpipe and the shell of the box body. Due to its structural design deficiency, there are many defects: 1. The lip of the sheath is prone to axial misalignment when it is assembled with the drainpipe Phenomenon, causing two semi-circular lip dislocations to be inserted into the drain pipe of the corrugated pipe, which will be damaged after long-term use; 2. In the design scheme where the sheath structure is spliced ​​with two semi-circular structures , due to a certain tolerance design, when the sheath is assembled with the drainpipe, there is a joint line on the surface of the sheath (see figure 1 or Figure 4 There is a design gap between the two semicircular sheaths combined line 101). Once the drain pipe is subjected to bending stress, the design gap will continue to enlarge, thereby affecting the aesthetics of the whole machine; 3. When the sheath is assembled with the drain pipe and the shell At this time, the distribution of buckles inside the sheath is not uniform, and the force is not consistent, and it is prone to dislocation in the radial direction, resulting in the existence of concentrated force areas, which directly affects the service life of the sheath.
