Abstract

The invention relates to a protection device detection system and electric heating equipment. A sealed cavity is formed in a protection device, a first electrode and a second electrode which are mutually independent are arranged in the sealed cavity, and the first electrode and the second electrode are respectively connected to a detection circuit. Under the condition that the protection device is not consumed so that water in the inner container flows into the sealed cavity, the sealed cavity in the protection device is in a sealed state, at the moment, the first end and the second end of the detection circuit do not communicate, and the detection circuit feeds back a first output signal to a controller. When the protection device is consumed to a certain degree, water in the inner container flows into the sealed cavity, so that the first electrode communicates with the second electrode, the first end of the detection circuit is connected with the second end of the detection circuit, and at the moment, the detection circuit feeds back a second output signal to the controller. According to the scheme, analysis and judgment of the consumption state of the protection device can be realized according to different signals fed back by the detection circuit.

Description

technical field [0001] The present application relates to the technical field of electric heating, in particular to a protection device detection system and electric heating equipment. Background technique [0002] With the development and maturity of electric heating technology, electric heating equipment represented by electric water heaters is used more and more widely in people's daily life. Electric water heaters refer to water heaters heated by electricity as energy. Generally, electric heating tubes, electric heating rods, glass tubes or plastic tubes are used for heating. And other advantages, are widely used in daily life. [0003] Because tap water generally contains a large amount of free metal ions, these metal ions will take away the free electrons of the heating rod (generally iron metal) without external interference, causing the heating rod to be corroded, which is easy to rust and damage. Based on this, a metal protection device with more active oxidation ...
