Description

Multi-functional efficient domestic coal range

The design relates to a kind of novel household coal stove device, it is characterized in that making the manually-operated of common coal kitchen range to be electrified operation, and collection saves time, laborsaving, energy-efficient, anti-pollution, decorative appearance is luxurious is one, is another novel household appliance kind in the family life.

The design is based on following consideration, and along with the raising of social life level, colour television set, washing machine, refrigerator have become important component part in people's daily life.Though these household electrical appliance can alleviate housework intensity from some aspect, save working time, better people's living environment the cultural life of adjustment family.But in conjunction with real-life situation, really time-consuming, effort, the poor again housework of environmental condition no more than kitchen housework, especially the kitchen kitchen range of three meals in a day based on the present situation of coal kitchen range, to pay attention to changing the residential environment condition not consistent with modern people especially.And national energy structure and applied cost restriction must make this present situation quite can not change in period.Therefore, people make every effort to improve coal kitchen range performance, with practical value and the operant level that improves common coal kitchen range.But, from domestic coal kitchen range improvement situation, be confined to just also generally that common secondary air is energy-conservation, heat supply heating, UTILIZATION OF VESIDUAL HEAT IN, in the simple and easy decorative appearance moulding.And the saving time of coal kitchen range, laborsaving, the improvement on the anti-pollution and navigability energy, it is also slower to make progress.Particularly use the new-type kitchen range of other energy constantly to occur, more make coal kitchen range performance seem backward as conventional kitchen range.But comment the promotion effect of new-type kitchen range reality, it seems that now most the sale also just is limited in big or middle city, certain popularity rate also arranged though both made in some city, in numerous families based on the coal kitchen range, gas, electric stove are auxilliary, and the phenomenon of various kitchen range coexistence is very common.Say that thus people's understanding also not only is confined to the advance of some new-type kitchen range, the use value and the various energy resource supply condition of various kitchen range considered in many-sided emphasis.With coal, electricity, gas is that the ratio of 1:5.3:3.67 is seen, the practical value of coal fuel and ease of use are the consumption ideas that relatively meets people, otherwise, if adopt modern technologies and production technology, impel the function of coal kitchen range and people's the modern life to match, so, this new-type coal kitchen range will be accepted extensively by society.

It is core with the electron controls technology that the design's purpose will provide a kind of exactly, and has " home electric multifunctional efficient coal kitchen range " electromechanical integrated device of correlation function.This device main feature is: the coal fuel in the stove stamen body adopts electronic speed-adjusting air blast, two-way self closing door air blast combustion-supporting, can make coal kitchen range rate of warming fast, and firepower is concentrated, the temperature height, and adjustable, and make the operability of coal kitchen range temperature accomplished.And effect when having obtained more common coal kitchen range tangible joint being arranged.To the high wind air supply stream, Circuits System has possessed high reliability low temperature interval adjusting and relevant anti-breath stove monitoring alarm function automatically simultaneously again, and the Artificial Control function that can regulate arbitrarily between the high-temperature region.For further improving the thermal energy conversion efficiency of coal fuel, the design has adopted six power-saving technologies, makes the more common coal kitchen range of this coal kitchen range can have energy-saving effect efficiently under identical ature of coal and quantity.Its six energy-conservation is: adjustable secondary air is energy-conservation, the water heater of UTILIZATION OF VESIDUAL HEAT IN, and it is energy-conservation that control is interrupted in the emptying of batch (-type) heat energy, the fire retardant energy-saving of banking up a fire, air blast air blast combustion-supporting and energy-saving, the ature of coal state is selected energy-conservation.Adopt electrified control technology in addition, can make loaded down with trivial details manually bank up a fire, scarfing cinder, the duration and degree of heating are grasped, time monitoring all has electric control gear to do, and operate intuitively, easy, therefore compare and have tangible labor-saving effect with common coal kitchen range.And on pollution prevention technology, the design has adopted the automatically controlled smoke exhaust ventilator of the integrated low bit architecture of complete machine system, 0.19 cube of meter per second of its air inflow, 0.22 cube of meter per second of capacity, the fresh air inlet that has solved other discrete smoke exhaust ventilator from some aspect blocks easily, greasy dirt falls to spattering, high-order spatial vision sense of depression and the high problem of unit price of installing.And in decorative appearance and moulding, the design has adopted modern high-grade household electrical appliances to decorate and the structural manufacturing process technology again, therefore compares with common coal kitchen range to seem luxurious, attractive in appearance, generous.Its key technical indexes is:

1, uses the coal fuel range: machine-processed honeycomb briquette, coal briquette, coal cinder, diffusing shape coal.

2, complete machine overall dimensions: long 70 centimeters, wide 55 centimeters, high 80 centimeters, smoke exhaust ventilator inlet and outlet air channel, top, kitchen range top plane board size: long 70 centimeters, wide 5 centimeters, high 45 centimeters.

3, supply voltage: alternating current 220V ± 10V

Control circuit voltage: direct current ± 15V

4, complete machine consumed power: control circuit≤10 watt

Smoke exhaust ventilator≤35 watt

5, complete machine weight≤40 kilogram.

6, mode of operation: but electric control operation, manually-operated when having a power failure.

The design is achieved in that in the limit wall of the stove stamen body circumference in coal kitchen range centre, evenly preset 6 long 13.5 cm diameters and be 0.6 centimetre duct, and the temperature detecting resistance silk with forward temperature coefficient spring shape shape can be set.300 ohm of every resistances, wherein per 3 are cascaded, and other component that can form two temperature detecting resistance bodies and control circuit input is combined into a unbalanced precise temperature measurement electric bridge.This principle is: the temperature that produces during the coal fuel combustion in the stove stamen body is heated the temperature detecting resistance silk and is caused corresponding change in resistance, through the d. c. voltage signal output that the measurement of electric bridge can produce a positive change, i.e. the forward dc voltage signal that temperature rising resistance wire resistance increases electric bridge output becomes big.The forward dc voltage signal that temperature decline resistance wire resistance reduces electric bridge output diminishes.Because the temperature detecting resistance silk is taked the vertical up and down many places of stove stamen body periphery continuous temperature measurement, can correctly reflect the state variation of actual temperature in the stamen body of coming out of the stove, and resistance wire directly do not contact high temperature and is enclosed in the duct, therefore have higher service life.Stove stamen body itself is selected high fire resistant materials moulding compacting sintering for use, has guaranteed the reliability and the quality of this coal stove device on the whole.In addition, the coal kitchen range does not rise before the temperature work, the low forward dc voltage signal of electric bridge output that makes of temperature of banking up a fire under the state in the stove stamen body is less, if at this moment press the work starting switch, this less forward dc voltage signal can not make the blower motor of actuating station and self closing door start rapidly effectively, the design has set up again on the brachium pontis of electric bridge with the on ﹠ off switch of banking up a fire thus, the starting switch key is controlled the resistance of two different resistances on the same brachium pontis respectively, so that two kinds be controlled at the output of different forward dc voltage signals difference arranged under the same temperature, realize that the operation of coal kitchen range is in the work starting state suddenly, can force the output signal of electric bridge to force to raise, reach the purpose that helps the pushing executing mechanism operate as normal.And the ature of coal state selects, and solved the problem unnecessary out of control that the discreteness of ature of coal is brought again preferably.We know that the ature of coal amount has certain discreteness, but the use of coal fuel has property in batches, therefore can make circuit control possess certain rules.Routine has been said the anti-burning of coal, and the not anti-burning of smut is run into such problem, and ad hoc ature of coal is selected the size of resistance on the adjustable economize on electricity bridge, just can change the state control range of control loop, promptly good coal temperature control wide ranges, smut narrow range.Analyze with the fat coal working condition, the bridge output voltage signal increases under the ature of coal selection resistance change ambassador uniform temp, and order about control loop and move in advance at the temperature ascent stage, and in the postponement action of temperature decline stage, and improved the operating rate of temperature ascent stage, reduced the geard-down speed of temperature decline stage.Be lower than the coal fuel of normal ature of coal for quality, this state of a control is just in time opposite.Need not to regulate for inflammable or nonflammable ature of coal difference, only because of adopting closed loop thermometric temperature adjustment technology, circuit control can realize adjusted in concert automatically, be that the fast cooling rate of the initial rate of climb of inflammable briquette is slow, be difficult for coal-fired starting velocity fast (notes: the logical actuating station blower motor rotary speed that refers to of above speed) of slowing down of lowering the temperature slowly.In addition, by the measurement of electric bridge to stove stamen body temperature degree state, the forward dc voltage signal of electric bridge output milli shape magnitude (2aV/ ℃), insert the in-phase input end of direct current linear operational amplifier with forward, after amplifying, amplifier can produce a forward dc voltage signal output that is proportional to input end signal (5-10 doubly) at its output, the promotion that has the emitter follower of high input impedance and certain fan out capability then by one-level just can be coupled in subordinate's state control network.State control network has 6 unit of function circuit to be formed, that is: high and low temperature level monitoring circuit, conditioning signal control gate circuit automatically, manual adjustments signal controlling gate circuit, rise, cooling state comparison circuit, low temperature is anti-to put out the stove monitoring alarm circuit, the auxiliary delay control circuit of banking up a fire.From high and low temperature level monitoring circuit function principle, it mainly is to undertake to judge whether coal kitchen range operating temperature is in low thermophase or hot stage (annotate: during the coal fuel combustion, the temperature that can not be extinguished is high temperature) under the maximum quantity of wind air blast.Top and end in the work of coal kitchen range, its variations in temperature is progressively to rise or progressively descend, owing to adopt the air blast air blast combustion-supporting, fail to be convened for lack of a quorum at low-temperature range high wind and to cause the stove accident of putting out, after this monitoring function was set, when making the work of coal kitchen range be in the intensification of low-temperature range and temperature-fall period, it was that kitchen range temperature random signal by the output of prime operational amplifier is controlled fully that its blower speed is regulated, that is: intensification is slowly quickened, and cooling is slowly slowed down.Its detailed process is: low-temperature range high and low temperature level monitoring circuit is failure to actuate, and guarantees that automatic conditioning signal control gate is in open mode, and turn-offs manual adjustments signal controlling door, and it is random signal control fully that air blast is regulated.Enter low, high temperature shift point (when the coal kitchen range has been in operate as normal) constantly, high and low temperature level monitoring circuit operation, therefore turn-off automatic conditioning signal control gate and open the manual adjustments signal gate, it is that artificial randomness is regulated (and minimum speed is greater than self-regulating maximum speed) fully that air blast is regulated, so that satisfy the needs that the duration and degree of heating of different cooking operations required and shortened the cooking time.When the coal kitchen range was operated in temperature-fall period and walks to low-temperature range, its control was as above said identical.The difference of this automatic adjusting and manual adjustment state is to show that light emitting diode indication and practical operation situation reflect and judge by being arranged on the anterior electric control operation dish of coal kitchen range.On the other hand; from, the anti-stove monitoring alarm circuit principle of putting out of cooling state comparison circuit and low temperature; they mainly are to undertake comparison, judgement in coal kitchen range variations in temperature is tending towards lowering the temperature the course of work; when temperature is reduced to the low-temperature warning limiting value; control circuit should in time send alarm sound; and close any Signal Regulation control gate and block shutdown, to treat can to make the rearming of coal kitchen range after the operator more renews coal.Because in the beginning temperature process of coal kitchen range work, its temperature rises also will be from low-temperature end through the anti-stove monitoring alarm measuring point that puts out of this low temperature, therefore can to distinguish out variation of temperature be to heat up or cooling to the state comparison circuit, and with the monitoring alarm circuit interlocked control, the warm process of accomplishing to begin is not reported to the police, and can report to the police when temperature-fall period coal kitchen range temperature is reduced to alarm monitoring point.In addition from bank up a fire the operation auxiliary delay circuit control function, we know that the monitoring temperature of banking up a fire under the normal rule is more on the low side, this is because after the sealing of coal kitchen range air door, the result that temperature is cooled off naturally in the stove stamen body, and after inserting the supervisory circuit of banking up a fire, when state of temperature is in the control point of banking up a fire when above, the blower motor of circuit actuating station will be opened the air draught door automatically with reverse rotation forces the air draught cooling fire-retardant to the coal fuel of stove stamen body.The realization of its function is to make the anti-phase place in circuit of air blast lead-out wire by the on ﹠ off switch contact of banking up a fire, although the outstanding of control signal all is that forward dc voltage and circuit supply are constant, because the anti-phase connection of air blast lead-out wire, therefore, the air blast of reverse rotation can make coal kitchen range temperature reduce to rapidly and bank up a fire below the control point, just meeting stall, and make air door realize sealing again.Just as described above, when the moment that the coal kitchen range is banked up a fire and operated after normal running finishes, new coal does not add the stove stamen or has just added and do not wait preheating, this monitoring function of banking up a fire can be from the high temperature attitude of moment or greater than the state of temperature of banking up a fire more than the monitoring temperature point, can make stove stamen body temperature degree reduce to the cold state of banking up a fire rapidly, the stove accident of putting out can may be caused, and set up after the auxiliary delay circuit of the operation of banking up a fire, can make the operation of banking up a fire moment air blast between 30 minutes time delays because of automatic conditioning signal door is closed can not backward rotation, be full of the time therefore for the preheating of new coal, and temperature can cool slowly naturally in the stove stamen body.After having only time-delay to finish, the backward rotation of air blast could realize.What also need here to explain is, blower motor is laterally assembling and sealing in the air-supply duct of coal kitchen range, flabellum adopts the vertical air feed of rigidity body, air door mechanism adopts the aluminium alloy plate hinge-type to connect, shutter, air draught door adopt tilting to fall to sealing naturally, and the big I employing of each door opening applies the balance weight iron adjusting on air door.In addition, the design is provided with time control function again according to actual needs, and therefore to having the cooking operation of time requirement, its operation is select time intuitively, finishes back circuit meeting autostop and sends alarm sound in the time.The realization of its control is to be finished by the triggering control point that clock-type mechanical timer selector is controlled blower motor drive wire and alarm sound circuit respectively time.The design of six power-saving technologies, select as the air blast combustion-supporting and energy-saving of above narration, ature of coal state outside the implementation procedure of energy-conservation, the fire retardant energy-saving of banking up a fire, mainly tell about here following three energy-conservationly be that intermittently heat energy emptying interrupts that control is energy-conservation, the water heater of UTILIZATION OF VESIDUAL HEAT IN, adjustable secondary air be energy-conservation.One intermittently heat energy emptying interrupts control energy-conservation to be by the side place on the coal kitchen range crater one pressure microswitch to be set, can to make the controlled connection of air blast when placing greater than the above weight of 500 grams, interrupt otherwise remove the work of weight air blast.For adapting to other situation, increased the continued operation function again, be that the function that heat energy emptying at intermittence is interrupted controlling is replenished, its realization is short circuit pressure microswitch contact.The water heater of its two UTILIZATION OF VESIDUAL HEAT IN is installed in the peripheral first half of stove stamen body, adopts corrosion resistant plate to make.And be reserved with admission line, funneling inlet channel, outlet pipe control valve and water level indicator tube.The energy-conservation realization of its three adjustable secondary air, be that to adopt stove stamen body periphery to set up two diameters be 2 centimeters ventilation shaft, its lower port is inserted stove stamen base upper end limit wall and is vented to air channel in the base, adopt moving, fixed pattern sealing ring isolation between its upper port and the stove stamen body crater, and leave air vent on the periphery of two circles, the angle of rotation moving-coil can change moving, as to decide air vent above sealing ring effective area, reaches the purpose that changes the adjusting of secondary air amount.The effect of this function mainly is that the secondary air pipeline is set separately, can improve the intensity of stove stamen body, the big thermal convection current ability of pipe diameter is strong, and can be by clogged by dust particles, when the operation of coal kitchen range electricity, can play the adjusting that cooperates the sealing usefulness of banking up a fire, be threaded to the secondary air energy-saving effect that to realize ideal the Maximum Ventilatory Volume position during power failure.Electronic scarfing cinder function is by 220 volts of DC-voltage supplies, can make d-c solenoid produce folk prescription to electromagnetic push moment in energising, and makes and push away slag metal magnetic conducting connecting rod and travel forward and drive shoveling.Cinder is pushed in the collection slag volume.After the outage, the extension spring at magnetic conductive metal connecting rod rear portion retracts the home position with connecting rod and shoveling.The smoke exhaust ventilator device is by the suction hole on inlet and outlet air channel its leftward position of plate that is installed in coal kitchen range top face rear portion, can be with in the waste gas inhalation machine, flow in the cleaning position of its bottom by the admission line that is parallel to the postnotum left side then, the greasy dirt that has wherein become liquid falls in the feculence box, waste gas is the double filtration by active carbon filter and screen pack then, enter high-order bit plasticity discharge duct again by suction fan to the discharge duct on right side, top again, discharge outdoor at last.The realization of appearance design is, coal kitchen range work top and plate front side, intake and exhaust air channel are selected corrosion resistant plate metal material punch forming for use, and all the other outer side planes are sheet metal mold punch forming and then spray paint, dry.Each decoration adopts electroplating technology, and the control panel front panel selects for use the oxidation technology moulding of sandblasting of alloy aluminium sheet to make.Balance adjustment when the coal kitchen range is installed can be realized by the balance adjustment leg of coal kitchen range bottom.

At first with reference to Figure 18, in the limit wall of stove stamen body (122) circumference, 6 microscler ducts (154) have evenly been preset, the spring shape resistance wire of forward temperature coefficient can be set, per 3 are serially connected, (4) in the temperature detecting resistance body (Fig. 3) of 2 similar resistance of composition, (5), so just can be connected to two of unbalanced bridge for measuring temperature shown in Figure 3 not on the brachium pontis of same-action, bridge for measuring temperature is by current-limiting resistance (7), Zener diode (11) provides about 10 volts normal voltage, during coal kitchen range operate as normal, operating switch key (52) normally opened contact closure makes semifixed resistor (1) insert electric bridge, the electric bridge output will have one to be subjected to the temperature controlled forward dc voltage signal of stove stamen body (122) this moment, it is increase in temperature, d. c. voltage signal increases, temperature reduces, d. c. voltage signal reduces, through coupling resistance (8), (9) transport to the in-phase input end of linear DC operational amplifier (10), high potential connects anode, electronegative potential connects negative terminal, change the size of feedback resistance (13), can change the voltage amplification factor of amplifier (10), the forward dc voltage signal that has amplified promotes pipe (14) emitter stage through the emitter-follower that certain fan out capability is arranged and is transferred to the late-class circuit network.Also designed the semifixed resistor (2) of the on ﹠ off switch of banking up a fire (56) normally opened contact control on the unbalanced bridge for measuring temperature, its effect is the low temperature control point when being convenient to select bank up a fire operation, the general resistance (2) of selecting can make circuit that different starting voltage output is arranged under uniform temp greater than resistance (1), operate as normal makes circuit control system that higher starting level be arranged, and when banking up a fire operation circuit control system is operated under the lower temperature state.Principle please refer to the temperature-voltage curve figure in the subordinate list explanation () in detail.The ature of coal that is installed on the operation board (102) selects adjustable resistance (3) to be connected resistance (4) upper end of bridge for measuring temperature, changes its size, can make the work of coal kitchen range all have the state of a control that adapts synchronous for the coal fuel of different quality.The principle explanation please refer to subordinate list (two) ature of coal selection mode--temperature relation table in detail.

The forward dc voltage signal that promotes pipe (14) output by emitter-follower shown in Figure 3 is coupled to the anti-extremely alert circuit of stove monitoring that puts out of low temperature in the control network shown in Figure 4, landing temperature state comparison circuit, the input endpoint of high low temperature level monitoring circuit and automatic conditioning signal control gate.Wherein low temperature prevents that putting out the stove monitoring alarm circuit is made up of level monitoring voltage-stabiliser tube (16), bleeder resistance (17), phase inverter (18), NAND gate (19).D. c. voltage signal VSr2 from prime during low temperature is less than normal, the voltage-stabiliser tube turn-on condition that can not satisfy VSr2=V1 can make voltage-stabiliser tube (16) end, phase inverter (18) input is gone into ground through bleeder resistance (17), be output as the input of high potential to NAND gate (19), whether NAND gate (19) moves warning, must satisfy the logical condition that two inputs possess high potential simultaneously, can make output is that electronegative potential is reported to the police.But another input of NAND gate (19) is the state comparison circuit interlocked control that has been subjected to, lowered the temperature, can not report to the police so that differentiate at the rising moment of temperature warning circuit, temperature descends when also reaching the alarm monitoring value again (VSr2=V1), and warning circuit could be reported to the police.The state comparison circuit that rises, lowers the temperature mainly is by state comparison amplifier (21), memory electric capacity (27), and emitter-follower promotion pipe (23), phase inverter (25), (26), ratio divider resistance (28), (29), (30) are formed.Its principle is: allow power circuit moment power supply during the startup working properly of coal kitchen range, because it is zero potential that the instantaneous charging of memory electric capacity (27) can make emitter-follower promote pipe (23) input, therefore resistance (24) upper end also is a zero potential, cause phase inverter (25) input high potential to make that phase inverter (26) output is an electronegative potential, an end that causes ratio divider resistance (30) is gone into ground from phase inverter (26) output is unsettled, and form inverting input that a V3 voltage receives state comparison amplifier (21) as reference voltage with top piezoresistance (28), compare with the VSr2 voltage on the signal transmssion line.Because the work of coal kitchen range is at the initial thermophase that rises at this moment, VSr2 can make state comparison amplifier (21) output remain on zero potential less than V3, again because of V3 greater than V1 monitoring alarm keying level, so keep relatively and the electronegative potential of stable phase inverter (26) output, will inevitably play another input that thermophase blocks NAND gate (19) coal kitchen range initial, allow it remain electronegative potential and do not report to the police.This state continuance is to VSr2 during greater than the conduction level V1 of voltage-stabiliser tube (16), the voltage-stabiliser tube conducting, and phase inverter (16) is output as electronegative potential, the signal that the request of releasing is reported to the police, and remain to the coal kitchen range and be operated in weary fiery temperature-fall period, in request, and work in anti-putting out in the monitor procedure that stove reports to the police.When VSr2 rises to greater than V3, state comparison amplifier (21) output end voltage progressively rises and makes emitter-base bandgap grading efferent duct (23) conducting, the voltage drop of resistance (24) is progressively increased, therefore phase inverter (25) is output as zero potential, phase inverter (26) is output as high potential, phase inverter (25) output electronegative potential can make ratio divider resistance (28), (29) inverting input of the dividing potential drop V2 access state comparison amplifier (21) of Zu Chenging, usually stipulate V2＜V1＜V3, because low temperature is anti-to be put out stove warning circuit phase inverter (18) output and had both made and be electronegative potential this moment, block NAND gate (19) input, so phase inverter (26) is when being output as high potential, NAND gate (19) can not reported to the police yet.Have only when ature of coal combustion reactive volt-ampere hour, temperature descends and makes VSr2＜V1, can not be satisfied with the condition that Zener diode (16) continues conducting, phase inverter (18) output is high potential again, and with input that the output high potential of phase inverter (26) satisfies NAND gate (19) simultaneously be high potential, reach the alert if that is output as electronegative potential.And the electronegative potential of NAND gate (19) output can make the unsettled ground wire of alarm sound circuit (61) among Fig. 6 go into ground, alarm begins to report to the police, and the electronegative potential of NAND gate (19) output also closes automatic conditioning signal control gate switching tube (37) by isolating diode (20), and the coal kitchen range is quit work.When this time of fire alarming lasts till VSr2＜V2, can make state comparison amplifier (21) output be electronegative potential again, phase inverter (26) output is that electronegative potential is removed warning, once more with the V3 voltage of ratio divider resistance (28), (30) inverting input of access state comparison amplifier again, V3 voltage is again as the primary condition of circulation next time.It should be to comply with can not misrepresent deliberately police, malfunction as principle that the size of above V1, V2, V3 voltage is selected, and satisfies the relational expression of V2＜V1＜V3.

High low temperature level monitoring circuit is by level monitoring voltage-stabiliser tube (31), and bleeder resistance (32), phase inverter (33) are formed.Its principle is, when the coal kitchen range is operated in the low-temperature range of initial intensification or weary fire cooling, because VSr2 can make phase inverter (33) end less than the conducting voltage V4 value of voltage-stabiliser tube (31), output is a high potential.The state value of this high potential is in the phase inverter (72) of Fig. 7 display circuit saturation conduction and allows light emitting diode (91) light, and is that the automatic signal adjusting need not manually to show the operator.In addition, the output high potential of phase inverter (33) will be by isolating diode (35) unsettled manual adjustments signal controlling door combination switch pipe (41), (42) biasing resistor (39), (40), the high potential that its multiple tube (41) (42) stopping and phase inverter (33) are exported can not influence the normal saturation conduction of automatic conditioning signal control gate switching tube (37), make its temperature variant DC voltage conditioning signal VSr2 promote blower motor (133) rotation by the power driving circuit that switching tube (37) is transferred among the Fig. 5 of subordinate at low-temperature range, be that temperature slowly rises, blower motor (133) slowly quickens, temperature slowly descends, blower motor (133) slowly slows down, and has therefore reached the anti-purpose of putting out the stove trouble free service of coal kitchen range.When the coal kitchen range is in normal work stage (between the high-temperature region), VSr2 will be greater than conducting voltage V4 value voltage-stabiliser tube (31) conducting of Zener diode (31), ordering about phase inverter (33) output is electronegative potential, making automatic conditioning signal control gate switching tube (37) input through isolating diode (34) is electronegative potential, the output stopping.Make the ground free end of going into of the biasing resistor (40) of manual adjustments signal controlling door combination switch pipe (41) (42) go into ground through phase inverter (33) output simultaneously, combination switch pipe (41) (42) obtains the condition of saturation conduction.At this moment the operator can be according to cooking operation needs, and the big I that is rotatably provided in the manual adjustable resistance (44) on the operation board (102) arbitrarily is achieved manual adjustment.In addition, the operation of manual adjustments can be in advance shows light emitting diode (90) among Fig. 7 by the electronegative potential of phase inverter (33) output through the A point to inform, and extinguishes the luminous demonstration of automatic adjusting light emitting diode (91) by phase inverter (72).When the coal kitchen range is operated in the temperature-fall period, phase inverter (33) ends when making VSr2＜V4 once more, can make supervisory circuit return to the status condition of low temperature control again, and the coal kitchen range has entered the preparation that next time circulates again like this.Its detailed principle please refer to the temperature shown in the table (three)--rotation speed relation curve map.Usually the selection of V4 voltage should normally operate to principle to guarantee the coal kitchen range greater than V3 voltage, rationally determines low, high-temperature control turning point.

Figure 5 shows that power drive amplifying circuit, blower motor (133) control logic change-over circuit.Control input signal VSr3 from Fig. 4, be coupled in voltage amplifying tube (46) input by resistance (45), voltage signal through the amplification of amplifier tube (46) is exported makes power drive multiple tube (48)) 49) work, and drive blower motor (133) rotation.Resistance (54) (47) is biasing resistor, and resistance (53) is feedback speed stabilizing resistance, and isolating diode (55), electric capacity (51), bleeder resistance (50) are formed a holding circuit that prevents motor coil back-emf breakdown power driving tube (49).The realization of its blower motor (133) logic control change-over circuit, be to press work starting switch (52) by the operator, make its normally opened contact be connected in the lead-out wire of blower motor (133) with forward, moving the breaking of normally-closed contact can be excised the reverse line of the switch of banking up a fire (56) contact, and air blast (133) is in the wiring condition that is rotated in the forward this moment.When banking up a fire operation, moving the closing of switch (56) normally opened contact of banking up a fire makes blower motor (133) lead-out wire oppositely connect circuit, the forward wiring of moving disconnected excision work starting switch (52) contact of normally-closed contact, blower motor (133) is in the wiring condition of reverse rotation this moment.Press pause switch key (57), moving the breaking of its normally-closed contact can be excised the drive wire of blower motor (133) by its stall.Stir its normally-closed contact of clock-type mechanical timer (60) and be in the moving disconnected state of time-delay, the time definite value arrives, and the back normally-closed contact is moving to break, and the drive wire of excision blower motor (133) is by blower motor (133) stall, the time-delay of the unsettled ground wire of alarm sound circuit (61) is located among Fig. 6 normally opened contact is moving closes and be connected on, can allow the unsettled ground wire (61) of alarm sound circuit report to the police with going into, the zero position of timer recovery time (60), this time-delay state is removed.Its pressure switch (58) is that sense switch is interrupted in the emptying of batch (-type) heat energy, the operational motion of this switch is to be subjected to the domination of coal kitchen range crater upper ends greater than the above weight of 500 grams, that is: the pressure of weight can make the normally opened contact closure of switch (58), blower motor (133) drive wire is connected, decontrol otherwise remove weight and switch (58) normally opened contact, make blower motor (133) stall.The function of continued operation switch (59) is replenishing pressure switch (58) function, that is: when coal kitchen range crater upper ends less than 500 grammes per square metre things reach corresponding action need constantly, continuously switch (59) but normally opened contact movingly close the normally opened contact of short circuit pressure switch (58), blower motor (133) drive wire is connected.

Shown in Figure 6 is the alarm sound circuit, its composition is to be combined into a multivibrator that is operated in the audiorange by two symmetrical triodes (62) (63) and relevant elements, two groups of primary coil windings of its power output transformer (64) are connected the collector loop of oscillating tube, and the secondary loudspeaker (65) that drives that can make the audio signal of variation directly promote power transformer (64) sends alarm sound.But the important process condition of alarm sound circuit is a unsettled ground wire (61) must ground connection.Therefore the alarm sound circuit is subjected to respectively as the NAND gate (19) in the anti-circuit that puts out the stove alarm monitoring of low temperature among Fig. 4 and the control of mechanical type time timer (60).Its alarm sound action time is to be subjected to the manual reset zero clearing of mechanical type time timer (60) and the retention time length restriction of NAND gate (19) alarm condition.Especially the duration of NAND gate (19) alarm condition is to be subjected to VSr2 among Fig. 4＜V2 transition speed control constantly, therefore stipulates that this time difference was generally 1.5 minutes.In addition, the alarm sound circuit is when banking up a fire operation, and the normally-closed contact of the switch of banking up a fire (56) will cut off its circuit power circuit and power supply (92) line, guards against the starting stage of the operation of banking up a fire, and produces false alarm.

Auxiliary delay circuit when Figure 7 shows that status display circuit and banking up a fire operation.Light-Emitting Diode among the figure (81) is the power supply indication, Light-Emitting Diode (82) is smoke exhaust ventilator work indication, (83) be electronic scarfing cinder indication, (84) are startup work indication, and (85) are the continuous operation indication, (86) be the operation indication of banking up a fire, (87) be the pausing operation indication, (88) are that the energy-conservation indication of control is interrupted in the emptying of batch (-type) heat energy, and (89) are time control operation indication, (90) be the manual adjustments indication, (91) are to regulate indication automatically.What mainly tell about here is the delay circuit operation principle of banking up a fire; By resistance (67), electric capacity (66) is formed the input endpoint that the RC charge circuit is connected in integrated circuit (69), the moment of switch (56) the normally opened contact closure of banking up a fire is connected power supply (92), RC begins charging, and to make integrated circuit (69) input be electronegative potential, output is a high potential, phase inverter (71) is output as electronegative potential, automatic conditioning signal control gate (37) among Fig. 4 is closed, work moment the sudden change cooling effect of banking up a fire of resistance shelves in high temperature blower motor (133) reversing constantly air draught, but do not influence to be in and press the on ﹠ off switch of banking up a fire (56) suddenly and air blast (133) the down draught cooling effect that causes (our purpose is the starting stage that makes the operation of banking up a fire, and the coal fuel that gives just to have inserted has certain preheating time) here in the hot stage manual adjustments process.Especially bank up a fire at low thermophase, automatically the conditioning signal door makes blower motor (133) stall because delay circuit acts on closed condition, and therefore bank up a fire out-of-control phenomenon below the monitoring temperature point of coal kitchen range temperature bust can not take place.After the RC charging interval in the delay circuit finishes, integrated circuit (69) is output as electronegative potential, phase inverter (71) is output as high potential, automatic conditioning signal control gate (37) is reopened, the supervisory circuit of can banking up a fire is recovered operate as normal, and delay circuit control is interrupted, and will remain to after the on ﹠ off switch of banking up a fire (56) the releasing operation, cuts off the delay circuit working power by on ﹠ off switch (56).

Circuit as shown in Figure 8 is the required positive and negative two groups of voltage-stabilized power supply circuits of control circuit, and its effect mainly designs in order to cooperate control system to use dc operational amplifier (10), (21).Wherein form the forward power supply by triode (73), (74), (75), the negative sense power supply is formed in triode (76), (77), (78), and the forward output power of power supply is greater than the negative sense output power of power supply.In addition, this bi-directional voltage stabilizing power supply voltage-stabilized power supply usually has the voltage stabilizing complementary characteristic, and its principle is not in narration.
