As preferably, one end of described heat-generating disc is connected with the normally opened contact of the first relay, and the other end is connected with the normally opened contact of the second relay.
Described second resistance is connected with master chip.
The beneficial effects of the utility model are: the bath devices that this close the cover could heat, increase the circuit do not heated when uncapping, can solve very well occur electric leakage time human body touching water tank in water or bathing time and cause the situation of electric shock to occur, lid closes behind correct position, and ensure that human body does not reach the water in water tank, just can start jug with heating disk, lid is opened, heat-generating disc at once power-off does not heat, thus the potential safety hazard avoiding heating meeting electric leakage electric shock occurs.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the circuit diagram of the bath devices that a kind of close the cover of the utility model could heat.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
Consult shown in Fig. 1, the bath devices that a kind of close the cover could heat, comprise magnetic switch unit 1, and the master chip 2 to be connected with magnetic switch unit 1, and the relay unit 3 to be connected with master chip 2, and the heat-generating disc 4 to be connected with relay unit 3, described magnetic switch unit 1 comprises magnetic switch 12, and the first resistance 11 to be connected with magnetic switch 12, second resistance 14 and ceramic disc capacitor 13, described relay unit 3 comprises the 3rd resistance 31, and the first triode 33 to be connected with the 3rd resistance 31, and the first relay 34 to be connected with the first triode 33, and the first diode 32 be connected in parallel on the first relay 34, and the 4th resistance 38 to be connected with another pin of master chip 2, and the second triode 35 to be connected with the 4th resistance 38, and the second relay 36 to be connected with the second triode 35, and the second diode 37 be connected in parallel on the first relay 34.
One end of described heat-generating disc 4 is connected with the normally opened contact of the first relay 34, and the other end is connected with the normally opened contact of the second relay 36.
Described second resistance 14 is connected with master chip 2.
Master chip 2 determines according to the low and high level that magnetic control unit unit 1 provides the incoming level height exporting to relay unit 3 circuit, thus make the first triode 33 of relay unit 3 and the second triode 35 be on off state, and then reach the heating object controlling heat-generating disc 4.Master chip: employing be the chip of the 2711MCU model that small household appliances industry is commonly used, have good stability.
Magnetic control element circuit: the first resistance 11, second resistance 14 and magnetic switch 12 (being tongue tube again) composition; The break-make of magnetic switch 12 is controlled (when installing on bath devices, the air line distance of permanet magnet and magnetic switch is no more than 10mm) by a powerful permanet magnet; When the distance of permanet magnet and magnetic switch 12 is more than 10mm, magnetic switch 12 is in off-state, and A point current potential is high level; When permanet magnet is close to magnetic switch 21 (distance is less than 10mm), the magnetic force that permanet magnet produces makes magnetic switch 12 be in on-state, and A point current potential becomes low level;
Relay unit circuit: this part is made up of the first relay 34, second relay 36, first triode 33, second triode the 35, three resistance 31, the 4th resistance 38, first diode 32, second diode 37; First relay 34 has the inserted sheet of two 6.3, and one is public access point, and another is normally opened contact, and common point connects the zero line input that 220V exchanges, and another one end connecing heat-generating disc 4 is connected; Second relay 36 is also two 6.3 inserted sheets, and one is public access point, and another is normally opened contact, and common point connects the live wire input that 220V exchanges, and another connects the other end of heat-generating disc 4; The incoming level obtained as B too low (not reaching the conducting state of the second triode 35), the second triode 35 is in cut-off state, and the coil of relay does not work, normally opened contact not adhesive, and heat-generating disc 4 can not be connected with zero line; Make the second triode 35 conducting, the second relay 36 adhesive when B obtains high level, heat-generating disc 4 connects with zero line; First relay 34 is synchronous with the second relay 36, and operation principle is identical; Heating when the logical upper 220V in heat-generating disc 4 two ends exchanges.
The beneficial effects of the utility model are: the bath devices that this close the cover could heat, increase the circuit do not heated when uncapping, water when occurring that heater leaks electricity in human contact's water tank can be solved very well and cause the situation of getting an electric shock to occur, lid closes behind correct position, and ensure that human body does not reach the water in water tank, just can start jug with heating disk, lid is opened, heat-generating disc at once power-off does not heat, thus avoids the potential safety hazard that heating can leak electricity and occur.
The above, be only embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed in the new protection range of this practicality and be as the criterion.
