Water inlet and outlet pipe of water heater

Abstract

A water inlet and outlet pipe of a water heater comprises a water pipe body and a water pipe seat, wherein the water pipe body is arranged in a water tank of the water heater, the water pipe seat is arranged outside the water tank of the water heater, and the water pipe body and the water pipe seat are connected integrally. A sealing plug is connected at the top end of an inner pipe in a buckled manner, the top end of the sealing plug is clamped in a plug support seat which is connected at the top end of an outer pipe in a clamped manner, a through hole fitted with the inner pipe is formed in an axis of an outer pipe support, the inner pipe is serially connected in the through hole, and the bottom end of the outer pipe is connected on the outer pipe support in a clamped manner to form the water pipe body. The water inlet and outlet pipe of the water heater has the advantages that structures of component parts are simple, multiple times of injection molding is replaced by buckling connection, and machining difficulty is lowered. The water pipe seat comprises a pipe seat base body and a detecting male tab, a hollow cavity is formed in an axis of the pipe seat base body, and the detecting male tab is fixed on the pipe seat base body via a screw. The detecting male tab is capable of detecting whether water in the water tank is electrified, so that dangers from electric leakage of the water heater and environmental electric leakage are avoided.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to an electric water heater inlet and outlet pipe. Background technique [0002] At present, the common water inlet and outlet pipes are generally composed of stainless steel outer pipe and plastic inner pipe. The stainless steel outer pipe and plastic inner pipe are connected by multiple injection moldings. The manufacturing process is relatively complicated and the manufacturing cost is high. Existing waterproof wall technology cannot completely solve the leakage problem of water heaters, especially environmental leakage. For the safety of the shower, a leakage protector is generally installed. There are two installation methods for the detection insert of the leakage protector: one is that the detection insert is directly installed on the expansion screw or the metal part of the water inlet and outlet pipe seat, and does not touch the water heater tank. Water, to detect whether the ...

The existing waterproof wall technology cannot completely solve the leakage problem of the water heater, especially the environmental leakage

For the safety of the shower, a leakage protector is generally installed. There are two installation methods for the detection insert of the leakage protector: one is that the detection insert is directly installed on the expansion screw or the metal part of the water inlet and outlet pipe seat, and does not touch the water heater tank. Water, to detect whether the water heater shell is charged; one is to detect whether the insert penetrates into the water heater tank to detect whether the water in the water heater is charged, but the installation is complicated
