Abstract
A power-off protection device of a water heater comprises a first line, a second line, a control module and a sensor, and is characterized in that the first line and the second line are led from the control module, and the sensor is connected with a signal end of the control module. The first line is connected with a mains supply, the second line is connected with a power source end of the water heater, and the sensor is installed at a water inlet or outlet of the water heater. When the water heater discharges water, the sensor can sense flow signals of water flow after a water outlet faucet is switched on and transmit to the control module, the control module cuts off power of the second line. When the water outlet faucet is switched off, the sensor cannot sense flow of the water flow, the control module restores power transmission of the second line, and the water heater keeps on working. The power-off protection device has the advantages that when the water heater starts discharging water by switching on the faucet, the power source can automatically cut off.
Description
Technical field
Water heater power supply automatic disconnection device was a kind of water heater power-off protection apparatus concretely when the utility model related to a kind of tap of fetching boiling water and discharges water.
Background technology
Water heater is that people one of must indispensable household electrical appliance, but no matter under the situation of using or not making, water heater is all keeping charged state to water heater, when will discharge water, the power line of water heater is still switched on the chamber electricity, bring harm can for like this people's personal safety.
Summary of the invention
The purpose of this utility model is to provide a kind of water heater power-off protection apparatus, has when opening the water heater tap and discharge water the function that power supply can automatic disconnection.
The utility model is realized with following technical scheme: a kind of water heater power-off protection apparatus, form by a line, No. two lines, control module, inductors.It is characterized in that: control module is drawn a line and No. two lines, and inductor is connected with the signal end of control module.No. one line is electrically connected with the city, No. two line is connected with the power end of water heater, inductor is installed in the water inlet or the delivery port of water heater, when using water heater to discharge water, opens the delivery port switch, inductor is sensed the flow signals of current and is sent it to control module, control module is cut off the electric energy of No. two lines, and when closing the delivery port switch, the inductor induction is flowed less than current, the molding piece recovers the power delivery of No. two lines, and water heater works on.
Beneficial effect is: have when opening the water heater tap and discharge water the function that power supply can automatic disconnection.
Description of drawings
Fig. 1 is the structural map of a kind of water heater power-off protection apparatus of the utility model.
No. 1. lines among the figure, 2. No. two lines, 3. control module, 4. inductor.
