Abstract

The invention discloses an electric water heater with a water scale detecting function, an alarming function and an automatic cleaning function. The electric water heater comprises a shell, an inner container and a control circuit, wherein a water feeding pipe is arranged in the inner container, and is connected with a water feeding valve after penetrating out of the shell; the water feeding valve is connected with a cold water pipe; the control circuit comprises a water scale detecting unit, a master control circuit and an automatic water scale cleaning unit; a signal input end of the water scale detecting unit is a water scale detector arranged in the inner container; a signal output end of the water scale detecting unit is connected with the master control circuit; a signal input end of the automatic water scale cleaning unit is connected with the master control circuit; a signal output end of the automatic water scale cleaning unit comprises an electromagnetic dirt discharging valve and a water feeding valve; the electromagnetic dirt discharging valve is arranged on a dirt discharging outlet on the electric water heater; the dirt discharging outlet is communicated with the shell and the inner container; and the master control circuit is also connected with an alarming unit. The shortcoming that the traditional electric water heater does not have a precipitated dirt detecting function, a precipitated dirt alarming function or an automatic precipitated dirt cleaning function is overcome; and the electric water heater provides healthful hot water for users.

Description

Technical field

[0001] The invention relates to an electric water heater, in particular to an electric water heater with scale detection, alarm and automatic cleaning functions. Background technique

[0002] After the electric water heater is used for a certain period of time, especially the storage type electric water heater, a large amount of scale is easily generated inside the electric water heater to form precipitation. When the scale thickens to a certain level, if it is not cleaned in time, it will not only cause the waterway to be blocked, water leakage, Increasing power consumption, etc., will reduce the water temperature, extend the heating time, reduce the water supply, and even cause leakage risks, and shorten the service life of the water heater. More importantly, it is harmful to human health. Long-term use of water polluted by scale can easily cause Various diseases of the human body endanger health.

[0003] At present, in order to prevent large amounts of alkali a...
