When a person getting warm leaves the electric warming device and forgets to turn off the working power of the electric warming device, no signals are output from the vibrating sensor, the delay control circuit unit is cut off, the power trigger switch is cut off, so that the power of the electric warming device is cut off automatically, the electric heater is powered off, and a fire accident is avoided.
Description
Technical field
The utility model relates to household appliance technical field, specifically refers to a kind of pedal type electric warming.
Background technology
Present pedal type electric warming on the market, great majority all are to use a kind of bimetal leaf Kick type temperature controller and hand temperature regulating switch as safety, control device.When excess Temperature, can only the temporarily disconnected heating power supply.Because this bimetal leaf Kick type temperature controller can recover again conduction after temperature lowers, can only of short durationly cut off the electricity supply, and repeatedly break-make work, fully cut-out working power that can not be real, and easily out of control or damage.Above-mentioned electric heater, when the heating people leaves electric heater and when forgetting powered-down, causes electric heater to work long hours, the waste power supply probably causes the on fire and breaking out of fire accident of covering on the electric heater.It is reported that the fire incident that a lot of families occur all be because cause the warming electric warmer to work long hours, and the covering that ignites is on fire, the initiation fire accident is sustained a great loss family's property.
Summary of the invention
The utility model technical purpose is to provide a kind of heating people to leave electric heater, when forgetting the working power of turn-offing electric heater, and the pedal type electric warming of energy automatic cut-off power.
The purpose of the utility model technology is achieved by following technical proposals: this pedal type electric warming, comprise electric heater, the relay power trigger switch, electric heater connects the relay power trigger switch, described relay power trigger switch connects the control time delay circuit unit, the output of control time delay circuit unit is as the input signal of relay power trigger switch, vibrating sensor connects the control time delay circuit unit, the output of vibrating sensor is as the input signal of control time delay circuit unit, and the break-make of relay power trigger switch is controlled by vibrating sensor.
Described vibrating sensing apparatus is below the foot-operated cover plate of electric heater.
Because the break-make of relay power trigger switch is to control by vibrating sensor, the vibrating sensing apparatus is below the foot-operated cover plate of electric heater, in order to better accept vibration signal, when on the foot-operated cover plate that people's pin or hand is placed on electric heater, in 10-20 minutes, the people always can unconsciously move, comprise to pressing down, upwards carry, to dragging of horizontal 360-degree direction, as long as slight action is arranged, vibrating sensor is sensed vibration, during output signal, the control time delay circuit unit just is in the conducting duty, the conducting of relay power trigger switch, the electric heater energising; When the heating people leaves electric heater, when vibrating sensor is not sensed the output of vibration no signal, to control time delay circuit unit and just be in the cut-off duty, the relay power trigger switch disconnects, the electric heater outage.Therefore, the heating people leaves electric heater, and when forgetting the working power of turn-offing electric heater, electric heater is the energy automatic cut-off power just, has avoided fire incident.Compare with existing electric heater on the market, the utlity model has following advantage: simple and reasonable, safe and reliable, stop fire incident and energy savings is remarkable.
The utility model is described in further detail below in conjunction with accompanying drawing and example:
Description of drawings
Fig. 1 is pedal type electric warming frame structure schematic diagram.
Fig. 2 is pedal type electric warming electric circuit schematic diagram.
The specific embodiment
With reference to Fig. 1, Fig. 2, this pedal type electric warming, comprise electric heater, the relay power trigger switch, electric heater S1, S2 connects relay power trigger switch J, electric heater S1, the S2 on/off is controlled by relay power trigger switch J, described relay power trigger switch J connects the control time delay circuit unit, the output of control time delay circuit unit is as the input signal of relay power trigger switch J, vibrating sensor M connects the control time delay circuit unit, the output of vibrating sensor M is as the input signal of control time delay circuit unit, and the break-make of relay power trigger switch J is to control by vibrating sensor M.
Described vibrating sensor M device is below the foot-operated cover plate of electric heater.
When using electric heater, K switch 1, K2, K3 is closed, press and once trigger key T, the A of relay power trigger switch J then, 2 conductings of B, electric current is through resistance R 5 and Z1, Z2, Z3, the Z4 rectification, capacitor C 3, C4, resistance R 6 filtering Z6 voltage stabilizings and resistance R 4, after capacitor C 2 step-downs, to other control circuit power supply, the control time delay circuit unit comprises ic chip 555, triode B1, B2, B3, R7, C6, electric current is through ic chip 555, the 3rd pin at ic chip 555 keeps high potential, through R12, D3 makes triode B1 be in normal conducting, and electric current is through K3, relay coil C, D, triode B1 makes relay A, B holds adhesive, be in normally on, bidirectional triode thyristor G conducting, electric heater S1, the S2 heating power, the resistance of change potentiometer W, can change the size by the electric current of bidirectional triode thyristor G, thereby reach control electric heater S1, the caloric value of S2.
Do not have signal when output when vibrating sensor M senses vibration, triode B2 is in cut-off state, and then triode B3 also is in cut-off state.At this moment electric current is through 6 chargings of 7 pairs of capacitor C of resistance R, (select by the numerical value to R7, C6 after charging a period of time, to the time fix on 10-20 minutes) current potential of the 2nd pin of ic chip can be elevated to certain numerical value, make the current potential of the 3rd pin of ic chip that upset occur and become electronegative potential, make triode B1 cut-off, then in the relay J C to the coil no current of D, A, B hold disconnection in the relay J, control circuit is without power supply, also not conducting of bidirectional triode thyristor G, and electric heater S1, S2 outage is not generated heat.
Once trigger key T when pressing, whole circuit is under the normal operating conditions, vibrating sensor M senses and vibrates when signal output is arranged, triode B2 is in conducting state, then triode B3 also locates conducting state, the electricity that then fills on the capacitor C 6 is let go by triode B3, the 2nd pin of ic chip always is in electronegative potential, the 3rd pin of ic chip high potential always then, then triode B1 is in conducting state, and C has electric current to the coil of D in the relay J, relay A, B holds adhesive, be in normally on, thus bidirectional triode thyristor G conducting, electric heater S1, the S2 heating power.
Because the break-make of relay power trigger switch J is to control by vibrating sensor M, vibrating sensor M is attached to below the foot-operated cover plate of electric heater, when on the foot-operated cover plate that people's pin or hand is placed on electric heater, in 10-20 minutes, the people always can unconsciously move, as long as slight action is arranged, vibrating sensor M will sense, triode B2, B3 is with regard to conducting, and the electricity that fills on the capacitor C 6 is with regard to zero clearing, be in electronegative potential on the 2nd pin of ic chip, just be in high potential on the 3rd pin, triode B1 conducting, then C has electric current to the coil of D in the relay J, relay A, B holds adhesive, be in normally on, vibrating sensor M whenever sends the signal of telecommunication one time, and the electricity that fills on capacitor C 6 will all bleed off once, zero clearing once, electric heater S1, S2 continues heating power.
Ic chip model 555IC, the model 9013 of triode B1, B2, B3, vibrating sensor M model VBS-03, all on sale on the market.
