[0051] The pipeline fixing assembly and dishwasher provided by the embodiments of the utility model will be described below with reference to the drawings.

[0052] Reference Figure 1 and Figure 2As shown, the utility model provides a kind of pipeline fixing assembly, it includes: connecting piece 10 and pipeline 20, connecting piece 10 includes joint main body 11 and sealing portion 12, sealing portion 12 is integrally connected to joint main body 11, joint main body 11 has at least two interfaces 111, sealing portion 12 is arranged in interface 111, and sealing portion 12 is flexible piece;Pipeline 20 is connected in interface 111, and sealing portion 12 is abutted between the outer wall surface of pipeline 20 and the inner wall surface of interface 111.

[0053] The utility model provides a kind of pipeline fixing assembly, connecting piece 10 includes joint main body 11 and sealing portion 12, by sealing portion 12 integrally connected to joint main body 11, can guarantee the stability of sealing portion 12 and joint main body 11 connection, prevent the problem such as sealing portion 12 drop or displacement, under the condition that pipeline 20 is connected in interface 111, sealing portion 12 effectively realizes the sealing effect between pipeline 20 and connecting piece 10, prevents the problem of liquid leakage, and sealing portion 12 also plays the effect of fixing pipeline 20.

[0054] The utility model provides a kind of pipeline fixing assembly, pipeline 20 is metal pipeline, metal pipeline usually has higher quality and aesthetic degree, especially in some dish washer products, more harmonious with stainless steel basket and other components, in addition, relative to plastic pipeline, metal pipeline has higher mechanical strength and high-temperature resistance, durable.

[0055] In a possible implementation mode, referring to Figure 3 And Figure 4 As shown, joint main body 11 has at least two interfaces 111, the number of interface 111 can be 2, 3 or 4 etc., can allow joint main body 11 to be connected with multiple pipelines 20, this design can be used for the pipeline system needing to be shunted or converged.

[0056] Sealing portion 12 is integrally connected to joint main body 11, joint main body 11 is plastic piece, and sealing portion 12 is flexible piece, and the two structures are fused together to form an integral structure by injection molding, which means that sealing portion 12 and joint main body 11 are inseparable integral structure, possibly realized by mold forming or other integrated manufacturing process, reduces installation steps.

[0057] Sealing portion 12 is flexible piece, and sealing portion 12 can adapt to the subtle difference between the outer wall surface of pipeline 20 and the inner wall surface of interface 111, to form a tight seal between the outer wall surface of pipeline 20 and the inner wall surface of interface 111, prevent leakage problem, provide effective sealing effect.

[0058] The sealing portion 12 is abutted between the outer wall surface of the pipe 20 and the inner wall surface of the interface 111 to ensure that the sealing portion 12 can maintain stable sealing performance under different temperature and pressure conditions. At the same time, the process of integrally connecting the sealing portion 12 with the joint body 11 needs to ensure the firm connection effect of the sealing portion 12 and the joint body 11 to prevent loosening or falling off during use.

[0059] The pipe 20 is a metal pipe, and the pipe 20 is an inner water pipe. The pipe 20 can be a stainless steel pipe or a copper pipe, and the pipe 20 forms a channel inside for water flow.
