Problems solved by technology

[0005] However, the above-mentioned invention cannot detect the function of the electric water heater due to the arc discharge of the internal wiring and electronic devices. The arc discharge is fast, difficult to detect and can quickly ignite the surrounding non-metallic materials, and the electric water heater fire accident occurs. Therefore The temperature information cannot be detected by the temperature sensor to make timely fire prevention measures

[0065] Further, the temperature detection device includes a temperature sensor 5 and a temperature signal processing module, the temperature sensor 5 is connected to the temperature signal processing module, and the temperature signal processing module is connected to the control module 6;

[0066] Wherein, the temperature sensor 5 detects the temperature signal in the electric water heater;

[0067] The temperature signal processing module receives the temperature signal detected by the temperature sensor, ...

Embodiment 3

[0075] Such as Figure 4 As shown, the control method of the fire-resistant electric water heater described in this embodiment, wherein the control method includes the following steps:

[0076] S1, start the electric water heater;

[0077] S2, start the arc detection device, and detect the arc information in the electric water heater in real time;

[0078] S3, the control module 6 judges whether the ignition arc signal is received, if not, then continue to execute step S2; if yes, then execute step S4;

[0079] S4. The control module 6 disconnects the relay and sends an alarm.

[0080] Further, step A) is also included between steps S2 and S3: start the temperature detection device, and monitor the temperature information in the electric water heater in real time.

[0081] Further, step B) is also included between step S3 and step S4: the control module judges whether an abnormal temperature signal is received in the electric water heater, if not, execute step A); if yes, e...

Abstract

The invention discloses a fireproof electric water heater and a control method. The fireproof electric water heater comprises an arc detection device and a control module, wherein the arc detection device is used for detecting a fire arc signal in the electric water heater, the arc detection device is connected with the control module of the electric water heater, when the control module receives the fire arc signal sent out by the arc detection device, a relay of the electric water heater is powered off. According to the fireproof electric water heater, the problem that the electric water heater cannot prevent a fire of the water heater in advance is solved, the fireproof water heater conducts analysis and treatment by detecting the arc signal of the electric water heater, when a fire arc signal having the fire capability is judged, the relay of the electric water heater is immediately disconnected, therefore the effect of early prevention is achieved, and the use safety of the electric water heater is improved.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a fireproof electric water heater and a control method. Background technique [0002] With the continuous development of society, many families have installed household electric water heaters. According to the heating power, electric water heaters can be divided into three types: water storage type (also known as volumetric or heat storage type), instant heating type, and rapid heating type (also known as semi-water storage type); water storage type is the main form of electric water heater According to different installation methods, it can be further divided into vertical type, horizontal type, floor type, under-trough type, and the latest integrated design integrated with bathroom cabinets. According to pressure or not, it can be divided into open type (simple type) and closed type (pressure type). However, electric water heaters are one of the products with the most safety acci...
