Description of reference numerals:
the intelligent monitoring system comprises an infrared switch 1, an internet of things switch 2, a touch switch 3, a green indicator lamp 4, a safety electromagnetic valve 5, a red indicator lamp 6, a normally closed auxiliary contact 7, a power line 8 and a radar switch 9.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the intelligent electric water heater safety protector is electrically connected with a power line of an electric water heater, and comprises a main contactor, an infrared switch 1, a green indicator lamp 4, a red indicator lamp 6 and a safety electromagnetic valve 5; the infrared switch 1 is connected with a coil of a main contactor in series, the green lamp and the safety electromagnetic valve 5 are connected with the coil in parallel, a main contact of the main contactor is connected with a heating pipe of an electric water heater in series, and the red lamp is connected with a normally closed auxiliary contact 7 of the main contactor in series.
Further, the infrared switch 1 is connected in parallel with an internet of things switch 2.
