Water heater water level maintenance system

Abstract

The invention provides a water level keeping system of a water heater. The water level keeping system comprises an inner container, an electric heating pipe, a water inlet pipe and a water outlet pipe, wherein the electric heating pipe, the water inlet pipe and the water outlet pipe are mounted on the wall of the inner container, one end of the water outlet pipe is arranged outside the inner container, and the other end of the water outlet pipe is a water inlet of the water outlet pipe and arranged in the inner container; a bonnet is arranged at the water inlet of the water outlet pipe, the lower end of the bonnet is connected with the water outlet pipe, and the bonnet is provided with a through hole; the through hole and the water outlet pipe are arranged coaxially, and the upper end of the bonnet makes contact with the upper wall of the inner container. According to the water level keeping system of the water heater, the bonnet of the water inlet of the water outlet pipe makes contact with the upper wall of the inner container, and therefore the situation that during mounting, the position of the water inlet is high, and consequently the water inlet abuts against the inner wall of the inner container and damages the inner wall is avoided; moreover, the water storage capacity of the inner container can be used effectively, and the water storage capacity is maximized.

Description

technical field [0001] The invention belongs to the field of water heaters, in particular to a water level maintaining system for water heaters. Background technique [0002] The water inlet of the outlet pipe of the water heater is generally arranged on the upper part of the inner tank, and the existing outlet pipeline is fixed on the outer threaded water pipe welded on the inner tank wall or the head, and the outlet pipeline is connected with the threaded water pipe by threads. Due to the different torques when the threads are tightened, the roughness of the threads of the threaded water pipes after sintering, and the thickness error of the sealing gasket, the height position of the water inlet of the outlet pipe after installation is inconsistent in the liner. If this position is too low, the water storage volume of the inner tank will be too small. If this position is too high, it will withstand the inner wall of the inner tank and damage the inner wall of the inner tank...

AI Technical Summary

Problems solved by technology

Due to the different torques when the threads are tightened, the roughness of the threads of the threaded water pipes after sintering, and the thickness error of the sealing gasket, the height position of the water inlet of the outlet pipeline after installation is inconsistent in the liner. If this position is too low, the water storage volume of the inner tank will be too small. If this position is too high, it will withstand the inner wall of the inner tank and damage the inner wall of the inner tank.
