Single phase poaer supply main line 45 links to each other with power supply indicator 18 and the zero line 46 common power supply indication loops that form;
Single phase poaer supply main line 45 links to each other with the pump startup loop and the zero line 46 common pump startup indication loops that form.Wherein, the pump startup loop is by SB 1Press button 19, KM normally opened contact 20 backs in parallel are connected to HL by discharge cock 21 2Pump startup indicator lamp 22, KM pump startup electromagnet 23 are formed.HL 2Annexation between pump startup indicator lamp 22, the KM pump startup electromagnet 23 is in parallel.
Single phase poaer supply main line 45 links to each other with heating circuit and the zero line 46 common heating starting indication loops that form.Wherein, the heating starting loop is by KM 1Normally opened contact 28, HL 3Burner on light 29 connects back and KM 127 parallel connections of heating electromagnet, SA again connects 1 Press button 24, KM normally opened contact 25, KA 1Normally-closed contact 26 is formed.
Single phase poaer supply main line 45 links to each other with temperature controller 30, passes through KA 1Relay 31 and the superthermal alarm circuit of zero line 46 common formation.
SA 2Press button 32 and KA 1After relay normally open contact 35 parallel connections, with SJ1 timing closing electromagnet timing closing contact 33, KA 2Relay 34 series connection are connected to and detect the loop when single phase poaer supply main line 45 is heated to zero line 46 formation;
KA 1Relay normally open contact 35 and SA 2After press button 32 parallel connections, link to each other with zero line 46, form temperature control timing loop with single phase poaer supply main line 45 by ST timing closing electromagnet 36; Single phase poaer supply main line 45 is through KA 1Directly be connected to HL behind the normally opened contact 37 438 form the overtemperature alarm loop together.
Single phase poaer supply main line 45 is through KA 1Relay normally open contact 39, SA 2Silence switch 40, HA 1 Overtemperature alarm bell 41 is communicated with zero line 46, thereby forms the overtemperature alarm loop;
Single phase poaer supply main line 45 is through SJ 2Timing closing electromagnet normally opened contact 42, HA 2The timing jingle bell 43 that finishes is communicated with zero line 46, finishes the prompting loop thereby form timing;
Single phase poaer supply main line 45 is communicated with zero line 46 through temperature controller 44, thereby formation temperature is provided with the loop; Wherein temperature is provided with the loop electrical schematic diagram as figure C, and it is by half (D of CD4011 147 or D 248) and R 1Resistance 49, R 2Resistance 50, C 1The multivibrator that electric capacity 51 is formed, RP 1Variable resistor 52, C 2 Electric capacity 53, VTH 1Diode 56, R 3Resistance 57, C 4Electric capacity 58 is formed upper limit threshold temperature controller TTS-202, RP 2 Variable resistor 54, C 3 Electric capacity 55, VTH 2Diode 59, C 5 Electric capacity 60, R 4The lower limit threshold temperature controller TTS-202 that resistance 61 is formed, and second half CD4011 (D 362 and D 465) and R 5Resistance 63, VT IGCT 67, R 6Resistance 66, C 6 Electric capacity 64 is connected to+and output circuit that 5V forms constitutes.The oscillator that employing is made up of D1 and D2 is exported the power supply of square wave as two TTS-202, its objective is temperature switch can be turn-offed after dropping to threshold temperature.VTH 1Diode 56 temperature switches are the ceiling temperature switch, VTH 2Diode 59 is the lower limit temperature switch, respectively by RP 1Variable resistor 52 and RP 2Variable resistor 54 is set (adjustment) its threshold temperature.I, II are two outputs, control heater by output high level or low level.
