The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details.
As depicted in figs. 1 and 2; safety and energy-saving electric heater of the present utility model; it comprises temperature adjustment and the switch assembly 1 that is installed in the casing 10; the holding circuit that cuts off self-lock module 2; passive type infrared induction and the automatic delay circuit module 4 that triggers; PIR probe 5; temperature detect switch (TDS) 6; continued flow resistance 7 and heater element 8; temperature adjustment and switch assembly 1; the holding circuit that cuts off self-lock module 2; passive type infrared induction and the automatic delay circuit module 4 that triggers; temperature detect switch (TDS) 6; heater element 8 is connected successively and is formed the heating loop; PIR probe 5 is with the passive type infrared induction and trigger delay circuit module 4 automatically and link to each other, is installed between passive type infrared induction and automatic triggering delay circuit module 4 and the heater element 8 after continued flow resistance 7 and temperature detect switch (TDS) 6 are in parallel.In the present embodiment, PIR probe 5 is the infrared ray pyroelectric sensor, and for example can adopt model is the infrared ray pyroelectric sensor of D203S; Temperature adjustment links to each other with 220V civil power live wire by power line with an end of switch assembly 1; the other end links to each other with the holding circuit module 2 that cuts off self-lock; passive type infrared induction and the automatic delay circuit module 4 that triggers; the MRT104-D86 human body infrared sensing switch that can adopt Min Hua Electronics Factory to produce; cancellation CDS (photo resistance) device; after 5 three lead-in wires of PIR can being popped one's head in simultaneously prolong, PIR probe 5 is fixed on the appropriate location of casing 10 lateral surfaces.Passive type infrared induction and the automatic delay circuit module 4 that triggers itself have three links: live wire is advanced with cut off self-lock holding circuit module and power-on button 2 to link to each other; live wire goes out that (with reference to model: KSD301-70) link to each other, zero line side links to each other with zero-power line with city dealer plain edition temperature detect switch (TDS) 6.Electromotion pilot lamp 3 is installed on the mounting box of the holding circuit module 2 that cuts off self-lock, with civil power and connect.Temperature detect switch (TDS) 6 with go out to be connected with heater element 8 and passive type infrared induction and the live wire that triggers delay circuit module 4 automatically respectively after continued flow resistance 7 is connected in parallel.The other end of heater element 8 is connected with the civil power zero line.Casing 10 is provided with reflect heat plate 9, and the resistance wire that continued flow resistance 7 adopts about 50-100W is installed on the reflect heat plate 9.
Operation principle: when needs use electric heater, the electric heater plug can be inserted civil power, open temperature adjustment and switch assembly 1, then power-on button be clicked, circuit can be connected, heater element 8 operate as normal.When temperature surpasses 6 limiting temperatures of temperature detect switch (TDS), this switch automatic disconnection, but still have little electric current to flow through continued flow resistance 7, and circuit still is communicated with, electric heater keeps lower temperature.No matter under which kind of situation, as long as heating person leaves 2～5 meters of electric heaters (promptly leaving the actual induction scope of PIR probe 5) 2～3 minutes, electric heater will cut off the power supply automatically.In the time of will warming oneself once more, as long as the power-on button that also must click again in the holding circuit module 2 that cuts off self-lock is just passable.
