Abstract
A water inlet and outlet pipe body of a water heater comprises an inner pipe, an outer pipe, a seal plug, a plug support base and an outer support, wherein the inner pipe is sleeved with the outer pipe, the bottom end of the seal plug is connected to the top end of the inner pipe in a buckled mode, the top end of the seal plug is clamped in the plug support base, and the plug support base is connected to the top end of the outer pipe in a clamped mode. A through hole matched with the inner pipe is formed in the axis of the outer pipe support, the inner pipe is connected in the through hole in a penetrating mode, and the outer pipe support is connected to the bottom end of the outer pipe in a clamped mode. The inner pipe is a long and thin plastic pipe which is good in insulating property and provides a water path with the enough length and the small enough sectional area to meet the technical requirement of electricity guard. The outer pipe is a stainless steel pipe, so that damage to the plastic inner pipe under the dry burning condition is effectively reduced. Water enters the inner pipe, flows out of an inner pipe water passing opening in the top end of the inner pipe to enter the portion between the outer pipe and the inner pipe and then flows into a water tank of the water heater through an outer pipe water passing opening. All the component parts are simple in structure, repeated injection molding is replaced by buckle connection, and therefore machining difficulty is reduced.
