Technical field
The present invention relates to water heater electric leakage protection technology field.
Background technology
The existing plug with earth wire live protector, such as all-purpose leakage protection plug, generally refer to be filled in protection Putting (plug) can be disconnected when phase zero line occurs and leaking electricity, and can be disconnected when being also included within ground wire electrification, and it is generally comprised by dynamic tactile bullet Property piece and stationary contact connection phase, zero, three poles, the zero sequence current mutual inductor through phase, zero line, test loop, amplification Circuit, rectifier, controllable silicon, electrical apparatus release, the zero sequence current mutual inductor through ground wire, it is except between detection load phase, zero line Whether there is outside leakage current, also detect whether ground wire has leakage current to pass through, when leakage separately or concurrently occur in phase line, zero line or ground wire During electric current, two detection coils can all make electrical apparatus release immediately by phase, zero, ground wire it is all off, that is, cut off the electricity supply, so that effectively Ensured personal safety, therefore oneself is widely applied in household electrical appliance.
The existing releasing structure that is concentrated through can automatically be powered off when electric leakage, but for the use of smart jack Power information and security information can not intuitively feed back to user, cause Consumer's Experience not good.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide the comprehensive leakage protecting plug of feedback of the information, Water-heater system and its method.
Above-mentioned technical purpose of the invention technical scheme is that:A kind of leakage protecting plug, bag Include leakage protection circuit, current detection circuit, voltage detecting circuit, electric quantity detecting circuit, wireless module and display circuit;Institute Stating leakage protection circuit carries out detection of electrical leakage to input power and carries out tripping protection to it, and current detection circuit is configured in real time The size of current of input power is detected, voltage detecting circuit is configured to the voltage swing of real-time detection input power, electric power detection Circuit is configured to calculate in real time uses electric energy consumption, and wireless module is configured to current data, voltage data, energy consumption data with wireless Transmission means sends, and display circuit is configured to display current data, voltage data, energy consumption data.
By above-mentioned setting, user can directly know the electricity consumption situation of water heater, real-time electric current and electricity on plug Pressure data can be shown on display circuit, by P=UI it is known that power situation in real time, W=Pt is known that energy Consumption situation, that is, which time period be in electricity consumption, and power consumption how, when possible summer, water heater energy consumption Can be relatively lower, and when winter, the energy consumption of water heater can be higher, the influence due to room temperature to water heater, it is general to use Family can not intuitively know electricity consumption situation, and to water heater ruuning situation nor be well aware of, so by setting display electricity Road, to improve Consumer's Experience, in addition and is equipped with wireless module, and data is activation can be gone out, and carries out remote data transmission.
Can be preferably as concrete scheme of the invention:The leakage protection circuit includes contact pin, the first indicator lamp, the One relay, the first transformer, first resistor, second resistance, 3rd resistor, the 4th resistance, the 5th resistance, the first electric capacity, Two electric capacity, the 3rd electric capacity, the 4th electric capacity, the 5th electric capacity, one-way SCR, the first relay, rectifier bridge, control chip;Contact pin Zero line connect the first normally-closed contact of the first relay, what the zero line side of contact pin connected the first relay second normally closed touches Point;The other end of the first normally-closed contact of the first relay connects the 6th resistance one end, coil one end, first of the first relay Switch one end, first indicator lamp one end, first winding one end of transformer;The first winding other end of transformer is used as output End, one end of the second winding of transformer connects one end of the tertiary winding and as another output end, the tertiary winding of transformer The other end first switch other end is connected by second resistance, 6th electric capacity in parallel, the 5th electricity on the 4th winding of transformer Resistance, the first pin of control chip and second pin;First pin of control chip is led to by the 5th capacity earth, second pin Cross the 4th resistance and connect the 4th winding, the 3rd pin ground connection, the 4th pin is drawn by the 4th capacity earth, the 5th pin connection four Pin, by the pin of the 3rd capacitance connection the 7th, the 7th pin is by the second capacity earth, and the connection of the 7th pin is unidirectional for the 6th pin The control end of controllable silicon, the 8th pin connects rectifier bridge by the first capacity earth, the 8th pin by 3rd resistor;Unidirectionally may be used Control the minus earth of silicon, anode connection 3rd resistor and rectifier bridge;Rectifier bridge connects the another of the 6th resistance and the first relay End.
By above-mentioned setting, when water heater normal work, indicator lamp is lighted, the normally closed linked switch of the first relay Contact:First normally-closed contact and the second normally-closed contact are closed, power network 220V civil powers by the first winding of transformer and second around Group is heated to heater.At this moment the electric current for flowing through the first winding and the second winding is balance, then the electricity of the 4th winding sensing Pressure signal exports low level by control chip on the 7th pin of control chip, then one-way SCR cannot be triggered and located In off state, at this moment the electric current of rectifier bridge can only meet and be powered to control chip, coil and the rectifier bridge string of the first relay Connection, the electric current very little for flowing through the coil of the first relay cannot be acted, water heater normal work.Once there is electric leakage in external power source Situation, the electric current for then flowing through the first winding and the second winding is just uneven, and the voltage change that the sensing of that the 4th winding is produced adds On control chip, the 7th pin output high level of control chip triggers controlled silicon conducting so that rectifier bridge electric current increases, The coil energized action of the first relay, its first normally-closed contact and the second normally-closed contact disconnect, and realize tripping protection, reach guarantor The purpose of shield bather's safety.And first switch be it is whether normal for hookup, can by control first switch come The leakage current of simulation is produced, it is thus whether normal to judge the work of this circuit.
