Preferably, the heat-shrinkable tube sleeve is made of a glue-containing heat-shrinkable tube material.

Preferably, the tee pipe fitting is made of plastic or metal.

Preferably, the joint tubing material comprises TPV.

The utility model discloses an improved washing machine inlet tube has following advantage at least:

1. the water inlet pipe pre-connecting structure has the advantages that part of the water inlet pipe is pre-connected, the water inlet pipe is better in integrity and sealing performance, more attractive in appearance, more convenient and faster to install, materials are saved, the clamp using amount of the washing machine for pipe connection is reduced, the phenomena of water leakage at the position of the water inlet pipe interface and the like which possibly occur in use are reduced, and the quality of the washing machine is guaranteed.

2. Because the rubber-containing heat-shrinkable tube sleeve is used as a main part for sealing and connecting, and the requirement on the sealing effect of the joint sleeve of the connecting tube and the tee pipe fitting is not high, the connecting tube material with better acid and alkali resistance, durability and the like can be selected, the requirements on the matching degree of the connecting tube and the joint and the like are also lower, the cost is reduced, and the service life of the pipe fitting is prolonged.

3. The leak-proof bulge is beneficial to increasing the connection tightness and ensuring that the connection between the connecting pipe and the three-way pipe fitting is firmer.

4. The connecting pipe is preferably made of TPV material, and has good thermal shrinkage combination and sealing effects.

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, an improved inlet pipe of a washing machine comprises: the three-way pipe fitting comprises a three-way pipe fitting 1 and a connecting pipe, wherein the connecting pipe comprises a water inlet pipe 2, a first water outlet pipe 3 and a second water outlet pipe 4, and the water inlet pipe, the first water outlet pipe and the second water outlet pipe are respectively connected with each joint of the three-way pipe fitting in a sealing mode through a heat-shrinkable pipe sleeve 5. The other end of the connecting pipe can be hermetically connected with other parts through heat-shrinkable pipe sleeves, hoops and the like.

The joint of the connecting pipe and the tee pipe fitting is sleeved, and the heat-shrinkable tube sleeve wraps the outer side of the connecting part of the connecting pipe and the tee pipe fitting, so that the connecting pipe and the tee pipe fitting are fixedly connected preliminarily.

The connecting pipe is sleeved outside the joint.

Each joint of the three-way pipe fitting is in a straight cylinder shape.

The heat-shrinkable tube sleeve is made of a glue-containing heat-shrinkable tube material. The glue-containing heat-shrinkable tube wraps the connecting part of the connecting pipe and the tee pipe fitting, and has good fixed connection and sealing effects on the connecting pipe and the tee pipe fitting.

The three-way pipe fitting is made of plastic.

The connecting pipe is made of TPV materials. The TPV (thermoplastic vulcanizate) material has good elasticity, compression deformation resistance, weather resistance, aging resistance and the like, excellent environmental protection performance and reusability, and in practice, the TPV material and the heat-shrinkable tube sleeve have good combination effect and are suitable for hot-pressing, welding and other processes adopted in the heat-shrinkable fixed seal.

Example 2

Similar to example 1, with the difference that the connecting tube is partly telescoped inside the joint. The relatively thin connecting pipe can adopt the connecting mode, so that the scheme can adapt to connecting pipes of more models, and the cost is saved. In actual production, a proper connection mode can be selected according to processing requirements or existing materials, and the same tee fitting can adopt the two connection modes of the embodiments 1 and 2 at the same time.

Example 3

As shown in fig. 2, similar to embodiment 1, it is different in that a plurality of annular leakage preventing protrusions 6 are provided on the outer side wall of the joint. The combination of connecting pipe and tee bend pipe fitting is inseparabler to the protruding messenger of leak protection, and the connecting pipe is more difficult for droing from the tee bend pipe fitting, and the sealed effect of leak protection is further strengthened.

While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields suitable for the invention, and further modifications may be readily made by those skilled in the art, and the invention is therefore not limited to the specific details and embodiments shown and described herein, without departing from the general concept defined by the claims and their equivalents.
