Problems solved by technology
[0002] The inner tank of the water heater in the related art is made of steel plates, so it is very rigid. However, when the water heater is in working condition, the pressure in the inner tank is changing, which requires the inner tank of the water heater to be both rigid and stable. Flexible, that is to say, it must be able to withstand high pressure and adapt to the constant change of pressure, while the inner tank of the traditional water heater cannot adapt to the constant change of pressure

Abstract
The invention discloses a composite liner of a water heater, a manufacturing method of the composite liner and the water heater. The manufacturing method includes the steps: S1, integrally connecting plastic pipe seals to one ends of metal water pipes so as to obtain water pipe components; S2, connecting the water pipe components obtained in the step S1 and a plastic liner into a whole, arranging upwards-protruding mounting portions at the bottom of the plastic liner, forming through openings in the mounting portion, enabling one ends, connected with the plastic pipe seals, of the metal water pipes to be connected with the mounting portions and communicated with the openings correspondingly; S3, winding fiberglass on the outer surface of the plastic liner connected with the water pipe components in the step S2 and performing curing. According to the manufacturing method, the mounting portions are arranged at the bottom of the plastic liner, so that the water pipe components can be mounted at the mounting portions conveniently, assembly efficiency is high, connection is reliable, and water is not easy to leak.
Description
technical field [0001] The invention relates to the field of electrical appliances, in particular to a composite liner for a water heater, a manufacturing method thereof, and a water heater. Background technique [0002] The inner tank of the water heater in the related art is made of steel plates, so it is very rigid. However, when the water heater is in working condition, the pressure in the inner tank is changing, which requires the inner tank of the water heater to be both rigid and stable. It is flexible, that is to say, it must be able to withstand high pressure and adapt to the constant change of pressure, while the inner tank of the traditional water heater cannot adapt to the constant change of pressure. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the present invention is to propose a kind of manufacturing method of composite inner tank of wa...
