The utility model compared with prior art has the following advantages and effect: can monitor the whether adhesion of heating relay module in real time, prevent that electrical heating is straight-through for a long time, prevent that long-term work electric energy loss and big electric current are anti-on fire.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the circuit theory diagrams of the anti-adhesion checkout gear of electrical heating.
Fig. 3 is the testing process figure of the anti-adhesion checkout gear of electrical heating.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment: referring to Fig. 1～Fig. 3, the utility model comprises display module 1, control module 2, detection of electrical leakage module 3, supercharging preservation and controlling module 4, water-level and water-temperature detection module 5, switch power module 6, heating relay module 7, auxiliary electrical heating module 8, key-press module 9, the anti-adhesion checkout gear 10 of electrical heating.
The anti-adhesion checkout gear 10 of electrical heating comprises switching diode D7, ceramic disc capacitor C6, photoelectrical coupler U2, resistance.Ceramic disc capacitor C6 is electrically connected with photoelectrical coupler U2, and photoelectrical coupler U2 is electrically connected with switching diode D7, and resistance is electrically connected with switching diode D7 and photoelectrical coupler U2 respectively.Resistance is made up of a resistance R 7 and No. two resistance R 9 of series connection.
It is that the relay that the terminal of L-OUT and N-OUT is connected to heating relay module 7 turn-offs on the pin that label is arranged among Fig. 2, when the electrical heating delivery of energy is exported, the just logical 220V AC alternating current of going up of these two pins, by a resistance R 7 and No. two resistance R 9 current limlitings, by switching diode D7 and photoelectrical coupler U2, make entire circuit form a path again.Because the light emitting diode of photoelectrical coupler U2 inside also belongs to diode, form the opposite unidirectional conduction device of direction jointly with switching diode D7, as with connection in scheming, have only when 220V AC alternating current during at negative half-cycle, it is luminous that the light emitting diode of photoelectrical coupler U2 inside is just understood conducting, not luminous during positive half cycle.According to the self-characteristic of photoelectrical coupler U2 as can be known, the continuous conducting of light emitting diode is turn-offed, thereby the triode conducting of photoelectrical coupler U2 inside is turn-offed, so can be the square wave that can occur cycle stability on the SOUT terminal at label, because the existence of ceramic disc capacitor C6, making label is smoother high-low level to occur on the same node of SOUT.Add the switch of control module 2 and judge, whether two relays that just heat relay module 7 as can be known adhesion.
