DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] In household appliances commonly used in people's daily lives, it is often necessary to combine two pipes 1 together and then fix them to other components, or it is necessary to fix a single pipe 1 to other components.

[0050] For example, a water heater usually includes a water tank, which includes an inner tank and an outer tank, a pipeline 1 is arranged between the inner tank and the outer tank, and the pipeline 1 includes at least a water inlet pipe and a water outlet pipe, one end of the water inlet pipe and the water outlet pipe are respectively connected to the inner tank, and the other end protrudes from the outer tank, and is respectively provided with a water inlet connector and a water outlet connector to facilitate connection with the water circuit outside the water heater.

[0051] In this case, generally, the connectors at the ends of the water inlet pipe and the water outlet pipe are wrapped and fixed with plastic at the same time by injection molding, or the connectors of the water inlet pipe and the water outlet pipe are wrapped and fixed with plastic respectively by injection molding, and then the injection molded parts are fixedly installed on the outer shell, so that the connectors of the two water pipes are fixed on the outer shell and can be connected to the external waterway.

[0052] However, forming the pipeline 1 and the pipeline assembly device as a whole by injection molding is not conducive to the separate production of the pipeline 1 and affects the production efficiency. At the same time, the injection molding and the mold required for the injection molding are expensive, which is not conducive to controlling the production cost.

[0053] The above is for illustration only and does not limit the types of household appliances to which the pipeline assembly device is applied. The pipeline assembly device can also be used to install pipelines 1 of other household appliances.
