Washing machine's inlet channel is connected with the running water, and water pressure is great relatively, and consequently, washing machine's inlet tube produces the vibration easily or sends the noise to, for other position pipelines, the condition such as leaking appears more easily, consequently, the inlet channel adopts the bellows to replace the straight pipeline of traditional outer wall to solve vibration and noise problem at present more.

In the plastic production process for many years, through constantly accumulating experience, we find that, in the pipeline of washing machine, the pipe fitting injection moulding with TPV or TPE material is high in production efficiency, good in use effect, strong in weather resistance and ageing resistance of the finished pipe fitting, good in fatigue resistance, and has better vibration reduction and noise reduction effects when used for the corrugated pipe, but because the cost is relatively higher, and the material is soft when thin, and lacks certain support strength, the corrugated pipe has not been widely applied in the corrugated pipe of washing machine all the time. In addition, as the arrangement of the pipelines inside the washing machine tends to be more compact and miniaturized, and as the functions of the washing machine are more and more, the design of the pipelines becomes more and more complex, the pipelines sometimes need to be bent appropriately, and the pipes injection molded by TPV or TPE materials sometimes have difficulty in adapting to large-scale bending or torsion.

Therefore, there is a need to provide a corrugated connecting pipe of TPV or TPE material with reasonable angle design and better support strength locally.

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 fig. 1-2, a corrugated connecting pipe for a water inlet pipeline of a washing machine comprises a corrugated pipe body, wherein the corrugated pipe body comprises a corrugated pipe portion 1, a first bent pipe portion 2 and a second bent pipe portion 3 which are respectively arranged at two sides of the corrugated pipe portion, the first bent pipe portion is provided with a first pipe orifice 4, the second bent pipe portion is provided with a second pipe orifice 5, the axes of the corrugated pipe portion and the first bent pipe portion form an included angle of 150 degrees, and the axes of the corrugated pipe portion and the second bent pipe portion form an included angle of 160 degrees of 130 degrees; the included angle between the plane of the axes of the corrugated pipe part and the second bent pipe part and the axis of the first bent pipe part is 20-60 degrees, and the included angle between the plane of the axes of the corrugated pipe part and the first bent pipe part and the axis of the second bent pipe part is 20-60 degrees; TPV or TPE material injection moulding's pipe fitting ductility and elasticity are less relatively, consequently need avoid the distortion of buckling of pipeline when the design as far as possible, according to the pipeline that corrugated connection pipe will be connected and the position relation of part, through assorted angle design, make the partly washing machine model of adaptation that it can be better, the distortion of buckling that receives external force that can be less when inserting washing machine pipeline, can effectively reduce the friction, the atress is even, reduce consequently the long-term in-use local strength step-down that leads to, the leakproofness scheduling problem inadequately.

In the first pipe orifice and the second pipe orifice, one side surface of the corrugated pipe part outside the first pipe orifice and the second pipe orifice is a conical surface 6. The setting of circular conical surface for first orificial front end thickness is the biggest, and first orificial department has sufficient support strength, makes first orificial front end have great area of contact simultaneously, conveniently cooperates with the connection of other parts, reinforcing leakproofness.

The outside of the first pipe orifice and the second pipe orifice is provided with a spring clamp 7. The spring clip is relatively inexpensive and, in general, provides sufficient sealing connectivity at the orifice. Spring clamp is established at first mouth of pipe and second pipe, and the complete set is used, and it is more convenient when the installation.
