Blow-down control system for water heater

Abstract

The invention relates to a blow-down control system for a water heater and belongs to the technical field of home appliances. The blow-down control system comprises an inner container and a blow-down control device, wherein the inner container is of a cubic cavity structure of which the upper part is larger than the lower part, and is used for storing water, a funnel-shaped blow-down outlet pipe for discharging dirt of the inner container is arranged on the lower bottom surface of the inner container; the blow-down control device is arranged at the blow-down outlet pipe and comprises a solenoid valve switch, a switch button and a monitoring system; the monitoring system is used for monitoring whether dirt exists in the inner container or not in real time; and the solenoid valve switch is turned on to discharge dirt and impurities of the inner container when dirt exists in the inner container. The inner container is quick in water temperature rise, high in hot water utilization ratio and energy-saving. In addition, such impurities as scale, generated after heating of water, are deposited at the bottom of the inner container in a centralized manner, so that the distribution area is small, and centralized complete cleaning is easy. The blow-down control system has the automatic blow-down dirt-removing function, realizes manual blow-down dirt removal and has an ideal cleaning effect.

Description

【Technical field】 [0001] The invention relates to the technical field of household appliances, in particular to a bathroom water heater. 【Background technique】 [0002] The water heater is a household device commonly used in the family. It is used to provide bathing water by heating the water body in the inner tank of the water heater. The heated water will produce solid scale, which will deposit on the bottom of the inner tank of the water heater. In addition, pollutants from the water source will also deposit at the bottom of the water heater liner. At present, the tanks of water storage water heaters on the market are relatively simple, and the lower bottom surface is wider. Impurities such as scale generated after heating are deposited on the lower bottom surface, which is widely distributed and difficult to concentrate on cleaning. Furthermore, the inner tank of the water heater is a closed chamber structure, and it is difficult to see the impurities inside the inner ...

AI Technical Summary

Problems solved by technology

In addition, pollutants from the water source will also deposit on the bottom of the water heater liner.

At present, the inner tank of water storage water heaters on the market is relatively single, and the bottom surface is wide. Impurities such as scale generated after heating are deposited on the bottom surface, and the distribution is wide, so it is not easy to centrally clean

Furthermore, the tank of the water heater is a closed chamber structure, and it is difficult to see the impurities inside the tank

If the scale and other impurities in the inner tank are not cleaned in time, these impurity pollutants will cause water pollution in the inner tank and seriously affect the sanitation of bathing water.
