Description

Presetting connecting pipe for L-shaped washing machine

Technical Field

The utility model belongs to the technical field of washing machine tubular product, concretely relates to L type washing machine presetting connecting pipe.

Background

The water and air pipelines inside the washing machine are more, the connectors of different parts are usually not on the same layer or in different directions, at present, plastic or rubber pipes with good toughness, bending property and water and corrosion resistance are adopted more and more to be properly bent to communicate the connectors of different parts and are sealed and fixed through clamps and the like, so that a good connection effect is realized, however, along with the increasing and more complete functions of the washing machine, the parts are more and more, the pipelines connected inside the washing machine are more and more complex, sometimes, one pipe needs to avoid other pipes or parts and can be smoothly connected with a target interface after being bent for 2-3 times, the effective area inside the pipe is influenced by excessive and overlarge bending, the trafficability is reduced, the bent pipe can generate certain resilience force to press other pipes or parts, and the weather resistance of the pipe and the sealing property of the interface can be influenced by long-term use, in addition, the more staggered pipes cause certain troubles to the assembly and maintenance of the washing machine, and the efficiency is affected.

In view of the above, there is a need for a washing machine connection tube with good sealing performance and pre-bending configuration.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a washing machine connecting pipe of bending presetting.

Another object of the present invention is to provide a washing machine connection pipe with better sealing performance and capable of using a clamp or a thermal shrinkage sealing connection at the joint.

In order to solve the technical problem, the utility model discloses a L type washing machine pre-setting connecting pipe for washing machine inside is walked water or is walked the gas pipeline, including first straight tube portion, elbow portion and second straight tube portion, first straight tube portion and second straight tube portion are linked together through elbow portion, and first straight tube portion and second straight tube portion axis contained angle are 70-110.

Preferably, the first straight tube portion, the elbow portion and the second straight tube portion are integrally formed of a TPV material. TPV (thermoplastic vulcanizate) material has good elasticity, compression deformation resistance, weather resistance, aging resistance and the like, and excellent environmental protection performance and reusability, and in practice, the TPV material is suitable for thermal shrinkage sealing connection, and the use of hoops and the like can be reduced.

Preferably, the inner walls of the pipe orifices of the first straight pipe part and the second straight pipe part are provided with a plurality of annular bulges which are arranged in parallel.

Preferably, the first straight tube portion and the second straight tube portion are vertically arranged.

Preferably, the first straight tube portion, the elbow portion and the second straight tube portion have an inner diameter of 8 to 10 mm.

Preferably, the first straight tube portion, the elbow portion and the second straight tube portion have the same or different inner diameters.

Preferably, the first straight tube portion, elbow portion and second straight tube portion have a wall thickness of not less than 2 mm.

The utility model discloses a L type washing machine pre-setting connecting pipe has following advantage at least:

1. through size matching, when the L-shaped bent pre-shaped pipe is connected with the connecting ports of different parts, the pipe does not need to be bent, and the connection can be conveniently and quickly completed; the pipe does not bend and deform, does not generate resilience force, does not press surrounding parts or the pipe, does not generate twisting force on the interface, and cannot influence the tightness of the interface after long-term use; moreover, the pre-shaping pipe can reduce the necessary length of the pipe, reduce the messy design of the internal pipeline of the washing machine and is beneficial to increasing the industrial aesthetic feeling of the internal design layout of the washing machine.

The pipe made of the TPV material can be connected with the connecting port of the component in a sealing mode through a hoop or thermal shrinkage mode, and when the pipe is connected in the thermal shrinkage mode, the annular protrusion on the inner wall of the pipe opening is beneficial to enhancing the sealing performance of the connecting port.

3. The first straight pipe part and the second straight pipe part have the same or different inner diameters and can be used for connecting two connecting ports with different diameters.

Detailed Description

The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," when used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

Example 1

As shown in figure 1, the L-shaped washing machine pre-setting connecting pipe is used for a water or air pipeline in a washing machine and comprises a first straight pipe part 1, an elbow part 2 and a second straight pipe part 3, wherein the first straight pipe part and the second straight pipe part are communicated through the elbow part, and the axial included angle between the first straight pipe part and the second straight pipe part is 70-110 degrees. In this embodiment, the first straight tube portion and the second straight tube portion are vertically provided. The length and the angle of the first straight pipe part and the second straight pipe part are set according to the relative position relationship (such as height, distance, middle obstacle and the like) of the two connecting ports, so that the connection is completed by realizing a short path and the forced deformation of the pipes as little as possible.

The first straight pipe portion, the elbow portion and the second straight pipe portion are integrally formed by TPV materials. The TPV material has the characteristics of low cost, heat shrinkability, good elasticity, strong weather resistance and the like, and can meet the requirements of washing machine pipelines.
