Heating body with water inlet loop air exhausting device

Abstract

A heating body with a water inlet loop air exhausting device comprises a preheating pipe, a heating pipe, a base, a cooling shell and an air-liquid separator, wherein the preheating pipe is connected with a water inlet pipe, the bottom of the preheating pipe is connected with the base and connected with the bottom of the heating pipe through a connecting pipe in the base, and the air-liquid separator is arranged on the top of the heating pipe. An exhaust outlet is formed in the top of the air-liquid separator, a slope is arranged on the inner wall of the air-liquid separator, and a water outlet is formed in the bottom of the slope. The air-liquid separator and the top of the preheating pipe are connected through an air exchange pipe which is located above the preheating pipe. A separating plate is arranged at the bottom of the air exchange pipe, and the bottom of the separating plate is lower than the joint of the water inlet pipe and the preheating pipe. The heating body with the water inlet loop air exhausting device has the advantages that when water is injected into an empty pipe of a heater, the problem of unsmooth exhausting of a U-shaped pipe is solved, the air pressure difference in water injection is eliminated, and zero-pressure water injection is achieved; in addition, through the added separating plate, the problem that the air exchange pipe loses efficacy due to the fact that a water column is sealed in the pipe because of the siphonic effect of the air exchange pipe can be solved.

Description

technical field [0001] The invention relates to an electric heating liquid heater, in particular to a heating body with an exhaust device for a water inlet circuit. Background technique [0002] In order to improve the heating efficiency of the liquid quick-heater and recycle the heat emitted by the electric heating tube to the heat dissipation shell, the company applied for the patent number CN201320303328.1 of the "water-cooled preheating heating body" in May 2013. Its heat dissipation outside the heating tube One or more preheating pipes are added to the shell to preheat the cold water before entering the heating pipes, and the preheating pipes and the heating pipes are connected through connecting pipes in the base. At the water outlet of the heating pipe, a gas-liquid separator is added, so that hot water flows out through the hot water port of the water dispenser, and water vapor enters the condensation pipe through the exhaust port. [0003] Since the preheating pipe...
