Device for incinerating waste components y

The innovation relates to a device for incinerating solid and liquid waste components in a combustion chamber an incineration toilet.

Combustion toilets are known to have those in the combustion chamber a grate is provided so that the solid and liquid waste components can be separated from one another (U.S. Patent 3,520,907). In this known device is a Jet flame from a pressure burner diagonally from above to below through one edge part of this grate into the space below of the grate initiated. Shielding plates ensure that no flame components enter the space above the real thing reach. The flame components can only enter the upper grate indirectly from bottom to top Get into the space of the deformation chamber. Here are the fixed Waste components on the grate only come from below from the jet flame washed around and scratched.

An electrically heated incineration toilet is also known in which the solid and liquid waste components are mixed be burned in a combustion pot, that is

7110 O SO-7.11η

no separating grating is provided, which, however, has a post-combustion chamber in the form of an opening into the combustion chamber pipe socket and in softer several heating rods are arranged, which extends into the combustion chamber takes place (US-PS 3 ^ 86 17 ¹ O- The case attainable temperatures in the Post-combustion chambers, however, cannot heat the exhaust gases to a point where they are completely odorless and the exhaust gases therefore still have a very bad odor.

In order to avoid these disadvantages of the known incineration toilets, the device according to the main claim is proposed according to the innovation. Further advantageous refinements of the device according to the invention emerge from the subclaims and the following description.

The combination according to the invention creates an incineration toilet which enables almost complete combustion of both the liquid and solid waste components without the formation of unpleasant smelling exhaust gases and which nevertheless has a very simple and compact overall structure. The solid waste products deposited on the grate are enclosed from above and below by the flame and at the same time the liquid waste products accumulated below the grate are also evaporated by the flame components running below the grate. In this way, almost complete combustion of the impact products is achieved. The resulting exhaust gases are practically completely odorless because of the additional post-combustion chamber. No additional energy consumption is necessary for this. The efficiency of a device according to the invention is therefore optimal. The outlet temperature of the exhaust gases released into the environment is kept at a relatively low value because of the post-combustion chamber. ^;

Figures J> to 9 show details of this device, partially in section along the cutting lines marked with Roman reference numerals.

Figure 10 shows the electrical control circuit for this device.

According to the invention, the waste composed of solids and liquids becomes a so-called soft Flame exposed * so a flame ^ which, for example, through an atmospheric burner is generated in which flammable gases such as propane under normal container pressure through a burner nozzle exits, in which the gas is mixed with air at atmospheric pressure and finally ignited. It is ensured that that the waste is maximally exposed to the flame, so that the solid waste components are completely incinerated and the liquid Components are completely evaporated. The vapor products that occur during this evaporation are then finally overheated * so that the steam in the elementary gas components is split up and becomes odorless in this way. The noiseless Combustion products are finally made by mixing

cooled with air and then expelled into the atmosphere. One such method is particularly for incineration toilets suitable and beneficial.

In the figures, an apparatus for the practical implementation of a method is shown, namely FIG. 1 a combustion toilet with a housing 15 # that has a bottom portion 17 and a cover 18 removably attached via a lateral flange 19. On the obsr side of the Cover 18 has an opening 20 in which it can be removed a triohter-like toilet bowl 21 is arranged, over an upper outwardly protruding edge 22 on the

At the lower end of the funnel of the bowl 21 is an outlet 51, ' provided, which is aligned with the opening of the seat 25 and: is designed so that it enters the combustion chamber 52 · ■ '

flows out. This combustion chamber 52 is formed by an above _r . open fire box yji formed _e of fixed or removable
1st arranged in untsren part of the housing 15 and also a suitable Abst & jnd of the outer walls of the device covers' ■ ses besitztρ so that appropriate thermal insulation therebetween
can be attached that allow heat transfer from the
Prevent combustion chamber on the outer walls of the housing. Em heat leakage from the combustion chamber 52 after
above is prevented by a lock in the form of two heat-insulated fire doors 5 ^, which are complementarily shaped to fit and each of which is about half
cover the upper opening of the combustion chamber. To that
to make the interior of the combustion chamber 52 accessible,
the two fire doors 5 ^ are separated from each other. To the-

6em purpose they have edges that protrude over one another and the opposite Ssitsr * of the box 25 are slidably supported in respective guide rails 25 which are attached to the upper edges of the box side walls.

A device enables the automatic opening of the Fire doors 24 when the cover 24 is raised and the doors are automatically returned to their closed position when moving down the cover 24. For this purpose are the couplings 2 ° »which are rotatable together with the shaft 25 are provided with downwardly projecting cams 27 with Roles 28 of transmission parts cooperate. These Transmission parts consist of vertical rods 29 of rectangular cross-section, which can be moved vertically back and forth between vertically spaced apart horizontally protruding flanges 40 of a frame part out cind, which on the inside of the rear upper Section of the housing 15 is attached. The rods 29 are normally by means of helical compression springs 42 upwards preloaded, which are supported with their lower end on the lower flange 40 and to the upper flanges 42 of the bars. In this way, the rollers 28 pressed against the cams 27 at the upper ends of the rods and follow them. The transfer of the vertical back and forth Movement of the rods 29 in corresponding opening and Base movements for the fire doors 24 are carried out via toothed racks 44 of the rods 29 above the shoulders 42, which with corresponding pinions 45 comb, which in turn with corresponding rotary shafts 47 are connected to and between the frame part 41 and a further frame part attached to the front upper section of the housing 15 48 rotatably mounted Bind. The drive connection between

the shafts 47 and the fire doors 34 takes place via two Angle lever 49, each attached to the shafts 47 are and before. which each end 50 in stores 31 to the outer edges of the associated fire door are stored. When the deokel 24 is raised, the cams 27 act About the rollers 38 onto the rods 39 and press them against the springs 42 near the bottom and thereby Ubor the racks 44, the pinions 45 and thus also the Shafts 47 rotated, whereby the angle lever 49 laterally be pivoted, as shown in dashed lines in FIG. 4 and in solid lines in FIG. As a result, the corresponding fire doors 34 are pulled into the open position, in which their inner edges expose the dispensing opening 31 of the bowl 21. By pivoting the cover 3 * into the closed position, the fire doors 24 are accordingly returned to the closed position pulled by the biasing springs 42, which when the lid is opened by the box downward movement of the rods 39 were compressed and pretensioned.

The mixture flame is inside the combustion chamber generated by a burner with a nozzle 52, the end of which through an opening 52 in the back wall of the box 33 ins Chamber interior protrudes · The nozzle 52 is preferably of the so-called atmospheric Venturi misoh burner design? it comprises a mixing chamber 52a for atmospheric air, into which the fuel gas via a line 54 from an Oasventil is supplied from a line 57 ″ which is arranged in the lower rear section of the housing 15. The nozzle A detonator 58 is assigned to 52. Preferably that is through the nozzle 52 produces plane tree "soft" and is either through Fuel gas such as propane, natural gas or another suitable one Combustion gas formed, which the nozzle 52 under usual

11_

Line or tank pressure is supplied and that is mixed with atmospheric air in mixer 52a, so because there is a beam of flames, like it does with one Fan burner is generated, the flame enters the chamber at a much lower speed and so the flame fills substantially the entire chamber 32. In order to achieve such a complete filling of the combustion chamber, narrow baffles are preferably also used 59 attached near the exit end of the nozzle 52. Additionally For better combustion, secondary air can still be used around the nozzle 52, through the opening 53 and into the combustion chamber 32 enter"

Inside the combustion chamber 32 is that to be incinerated Material Exposed to the flame in an optimally effective manner. The loose waste components are essential in enveloped in the flame and the liquid waste components separated from the solid components are not only removed from but also heated from below via the flame generated by the nozzle 52 and evaporated in this way. this will This is essentially achieved in that the solid components are placed on a grate 60, which is preferably designed as a perforated plate, on which support flanges 61 are formed integrally therewith on opposite sides are, which are preferably also perforated and which allow the grate inside and above a liquid 8collecting strap 62 removable support. According to FIG. 2, the grate 60 has downwardly diverging, relatively narrow deflecting flanges on its front and rear edges 63. The grate 60 is preferably mounted above the upper edge of the shell 62 and at a height that the Position of the horizontal axis of the nozzle 52 corresponds. The flame

of the nozzle 52 thus closes the solids compartment M (FIG. 2) lying on the grate 60 not only above but look beneath the perforated grate. The evaporation of the liquid components in the tray 62 is reached by branching off the flame at the rear end of the shell downwards also in the area below the shell namely along the downward and forward sloping rear wall 6 ^, through which part of the flame is branched off under the shell 62> the one above the bottom of the combustion chamber 2 »2 by the supports 65 and is held, which creates a space under the shell. Although the shell is dimensioned so that a There is distance between the sides of the box 23, such as

! This Figure 5 shows, it has in addition not only from

■ the rear wall of the box a sufficient distance so that

^! the heating flame can pass between them, but

it is also spaced from the front wall so that there is also a good flame effect between the front wall the shell and the front of the box

and the flame from the area below the bowl itself

j can unite with the rest of the flame and the combustion

! @ products and evaporation products can reach an exit opening f 68 in the front wall of the box, which just

if substantially aligned with the grate 60.

The working temperature in the combustion chamber 32 is large

enough to burn the material M and to evaporate the liquids and the steam constituents and the products of combustion are withdrawn via the opening 68. If these combustion products would be released directly into the atmosphere., the smell of these exhaust gases would be very annoying. It is therefore an overheating device is provided for these steam modules

see to these break down and into their elemental gas constituents to remove the odor before the exhaust gases are released into the atmosphere. In the simplest case this is an overheating device another chamber 69, in and through which all combustion and vapor products as a unified jet from the Outlet opening 68 must pass through. Preferably, the chamber 69 is formed by a channel 70 which extends horizontally the front side of the box 33 is formed and which is then bent backwards along a side wall after a bend this box 33 continues. The channel 70 can, for example simply be formed by a sheet metal that is attached directly to the outside of the box 33 and utilizes the sections of this box 33 as a part of the duct wall. As a result, the chamber 69 does not become only heated by the fact that the in the combustion chamber 32 beginning and continuing through the opening 68 into the canal Combustion of gas and air continues continuously, but also due to the heat coming through the sheet metal wall of the box 33 is transferred and that is added to the heat that is immediately zJdcullert in the channel. In this way the steam products in the duct are overheated, namely up a temperature of the order of 5 ^ 0 ° Celsius, so that when the gas flow has passed through the chamber 69 and the outlet extension 71 (FIGS. 5 and 9) of the channel 70 achieved, this stream consists only of elementary gases and light, incombustible fly ash components that are in it may be included.

At the outlet 71, the gases are still too hot to be able to safely release them into the atmosphere. So let it still a device for the simultaneous cooling of the gases is provided. In the exemplary embodiment shown, this cooling is carried out by Mixing the gases with a large amount of atmospheric air

reached when the gases through an air gap 72 between the discharge end 71 and a mixing chamber 7? be sucked through. The mixing chamber 75 is formed by an elongated, vertically arranged housing 7 ^, which preferably has a rectangular cross section. In the wall of this housing opposite the outlet 71, an inlet opening 75 is formed near, but at a distance above the floor, which is aligned with the outlet end of the channel and is preferably larger than this outlet. In order to suck in the hot gases and the cooling air into the chamber 73, a suction effect is generated, by means of which the cool gas and air mixture is also drawn off from the mixing chamber 73 through an outlet opening 77. The opening 77 is arranged in the lower section of a side wall of the housing 7 ^. When the air-gas mixture is moved from the inlet opening 75 to the outlet 77, plug ash or other solid components contained therein fall onto the collecting base of the housing within the mixing chamber 73. The suction effect is generated via the opening 77 by a fan, which is of the cage type, for example, and is formed by a rotor within a housing 78 which is driven by a motor 79. A vent 80 leads from the fan housing 78 directly to the atmosphere or into a vent pipe which is preferably still provided. In order to clean the mixing chamber 7 ^ it is preferably fastened in a removable manner, as shown in FIGS. 8 × A 9. It is held by projections 81 which can be slid into upwardly open vertical slots 82 in hangers 83, which in turn are fastened to the fan housing 78 and thus accommodate the mixing chamber between them. The fan housing 78 is in turn supported by holders 84 which are fastened to the housing 15 in the upper region. The mixing chamber and the fan are normally covered by a hood 85 in the rear section of the cover l8, which can be permanently or detachably attached to this cover l8. It is preferably removable in any case so that the rear area of the seat and the combustion chamber are accessible for cleaning and the like.

Since the mixing chamber 73 is arranged within the housing 15, the fan generates a pulling effect within the housing, thereby venting the interior of the housing during use. During the incineration, the venting effect not only is cooling air drawn into the housing from the environment through the various housing openings but also heated air is sucked out of the housing, whereby the thermal insulation in the housing and the housing walls is improved and thereby the outer surfaces of the Keep the case cool "

If larger amounts of steam are generated by heavier loading, unusually large amounts of liquid waste, frequent use or the like, or there is a risk that such larger amounts of steam will actually arise in the combustion chamber 32 than actually in the overheating chamber 69 due to the heat generated by the primary flame of the burner 52 can be overheated, then additional heat can be supplied to the overheating chamber 69 by afterburner according to FIG. The channel 70 has this purpose χ an inlet section 87 * which is generally a service associated with the channel additional channel portion which is located on the side of the combustion chamber 22, which is opposite to the channel 70 and the outlet 7I transmitting side, an open inlet 88, combustion air is sucked into this additional duct section 87 to a gas flame nozzle 89, which acts as an afterburner and which, with the air sucked in and mixed through opening 88, generates a flame in the duct with such a heat that the primary burner of the combustion chamber passes through the opening 68 supplied heat is increased and so the amount of steam is sufficiently overheated so that it is split into the odorless primary gases. Of course, corresponding electrical heating devices can also be used.

services should be provided, albeit also for the primary flarrane a gas burner is used is preferred a gas flame is also provided for this afterburner.

In order to ensure safe and effective operation of the incineration toilet, the operation is monitored via an electrical control or monitoring circuit. The circuit is shown in FIG. 10. It includes its network connection 100, 101 for connection, for example a ** 125 volt, 60 Hz alternating current network. The connection 100 is with

one end of a primary winding 108 of a step-down transformer 107 connected via the series connection of a fuse 102, a normally closed switch 103 as well as a contact 104, who with a contact cooperates. The connection 101 is connected to the second end of the winding 108 via the series connection of the contact 109, which cooperates with a contact 110, in connection. The Ij input voltage is thus in the secondary winding 112 of the | j Trails forma to rs 107 and then leveled with a bridge he II6 fed through a contact 113, the cooperates with a contact 114 and a contact 117 * ^ which cooperates with a contact IIS. The bridge rectifier 116 comprises several diodes 120 to 123, dia as full-wave rectifiers are switched for the AC voltage. Two diodes 121 and 122 are connected to their anodes and grounded while the other diodes 120 and I23 with each other and connected by conductor 124 to normally closed switch I30 which indicates that the chamber is properly seated.

Resistor I3I is in series with capacitor I32 connected to earth and connected to the cathode of a zener diode

124 through a resistor 132 in connection. In a practical Embodiment were integrated circuits, such as si © under the trade name "Motorola mc γ4ϋϋ P" are known, which require a supply voltage of 4.7 volts ODCfin. The resistors IJl and 135 and the Capacitor 132 together with Zener diode 134 form a Filter regulator with an output voltage + V of 4.7 volts direct current. Of course, other circuits can also be used.

The switch 103 has a locking function and it is open the rear of the housing 15 (Figure 6) attached. He knows a switching nipple 103a which cooperates with the top of the cover 18. The switch 123 (FIG. 9) is at outlet 71 of the canal and feels the temperature of the elementary gases that pass here. This thermostat switch is on a Temperature of around 760 ° Celsius is set and switches off the thermal circuit for the burner as soon as the exhaust gas temperature is too high is detected. This thermostat switch must be reset manually before the device can be switched back on Operation can be set, which is done via a push button 128.

The integrated circuits mentioned preferably consist of several positive NAND gates, each with two inputs, via which the operation of the toilet is controlled. Two first such gates 135 and 136 are interconnected in a known manner to form a multivibrator. Two further gates 137 and 138 form a second multi-vibrator. The output 139 of the gate 135 is connected to the input 14l of the gate 136. In the same W _e ise the output of gate 142 is I38 connected to the input 144 of the gate 137th

When a voltage is applied, two capacitors 155a and 191a are connected to the outputs 155 and I91 of the Multivibrators each momentarily held the voltage «

'■.) so that the multivibrator is tilted into the desired position. Output 139 is in this position and input 14l of gates 135 and 136 high Potential. The input 145 of the gate 146 is thus also connected to a higher potential, the other input 147 already has a higher potential because it is above φ the resistor 148 is on the voltage + V. The exit

* 149 of this oatter is therefore due to low potential.

This output 149 is connected to the base of a transistor

151 connected through a resistor I50. This transistor 1 ^ 1 stands with its emitter on the base of a transistor

152 is connected and its collector is connected to the collector of transistor I52. The emitter of transistor 152 is grounded and its collector is connected to the DC voltage on line 129 (12 volts DC voltage) via motor 70 . The low potential at the output 149 of the gate 146 can therefore make the transistors 151 and 152 non-conductive. The motor 79 therefore remains off

_Ä switches.

* The output 153 of the gate I36 is connected to the input 154 of gate 135 connected. At this point in the operating sequence, output 153 is at low potential and this lower potential is also at input 155 of the Gate 157. The higher potential at the output 142 of the gate 138 is at the input 156 of the gate 157 * with a higher one Potential at input I56 and a lower potential at The gate 157 has input 155 at the output 158 higher Potential. The output I58 of the gate 157 is connected to the input 159 of the gate I6I. This gate I6I i

- 15 -

has another input 160, which has a Resistor 162 is at the supply potential + V. The output I63 of the gate Ιοί is at low potential * because his Inputs 159 and I60 have high potential. The output I63 is connected to the base via a resistor 164 of a transistor I65 in connection, which in so-called Darlington circuit with a second transistor 165a is together. The transistors I65 and 165a cannot initially reach the lower potential at the output 163 make conductive.

The transistors 165 and 165a are with the Bre: ..- jnerkreie interconnected. In the circuit state described so far, the motor 79 is switched on light and can therefore also do not generate any air flow and the burner is not yet effective either «

Operation is initiated by connecting the circuit to the Mains is switched on or when, as detailed below is described, the chamber doors J4 are opened, so that + V potential of the collector on transistor 212 to the Input I67 of gate I63 arrives as a short pulse and the multivibrator tilts, so that the output 129 low Potential and the output 15? high potential. That The resulting low potential at the input 145 generates a higher potential at the output 149 of the gate 146, which in turn makes the transistors 151 and 152 conductive and thus switches on the motor 79. · The motor 79 generates with it an air stream through the fan. This air flow is monitored by a wing switch 23O on the fan housing (FIG. 9) is attached and has a flag 21, which is coupled to a contact 232. The closed switch 230 thus indicates the presence of an air stream.

The higher potential at output 155 of the gate causes a change at input 155 of gate 157 of the output 15 ° south aisdsrssi potential. This lower one Potential acts at the input 159 of the gate l6l and thus generates a higher potential at the output 16 ^. The higher one Potential at output I65 acts via resistor 164 and makes the transistors I65 and I65a conductive. However, these transistors 165 and 165a can still power the burner do not switch on, because the cover 24 is still raised and the chamber doors} 4 are still open. The burner can therefore not yet be effective.

The control circuit remains in the state just described and nothing happens until the toilet lid 24 is lowered. As a result, the chamber doors J4 are closed in the sense of the above description. A switch 168, which is fastened to the frame 48, is assigned to one of these chamber doors. This switch 168 has an actuating nipple 169 which, when the associated chamber door 34 is closed, is actuated via a cam section 170 of the shaft 47; will. The other chamber door is associated with a switch 171 in a similar manner, which is also fixed to the cross frame 48 and having an actuating cam 172 of the shaft is actuated by a cam \> \ J> 47th The switches 168 and 17I are electrically connected in series with the burner circuit and ensure that the doors 24 must be completely closed for ignition and operation of the burner to be possible.

The burner includes two solenoid valves through which modulation of the input is possible. The first valve is not shown, but it acts between the collector of transistor 165 and the junction point 176. The valve used for modulation is controlled over the winding 175 * which is in series with one on 510 ° Celsius set thermostat switch 177 is located, which is arranged according to Figure 9 ara output section 71 of the channel is. After closing switches 168 and

171 when the doors J> h are operated, a relay 172, preferably a reed relay, is switched on, the contacts 175 of which are in the ignition circuit 174. When the contacts 173 close, a voltage divider is effective, which comprises a resistor 175 » contact 177 cooperating with contact 176, the switch 175, a contact 179 cooperating with contact 180 and a resistor 182 parallel to the supply voltage. One end of the resistor 182 is connected to the static electrode of a controlled silicon rectifier 185, via which the ignition circuit 174 can be switched on and an ignition spark ara gap 184 can be generated.

The circuit also includes a flame monitor holder I85 with a flame sensor I86 (Figure 5) that opens, as soon as a flame is detected, whereupon the relay

172 switched off and the contacts 17j5 opened and so the Ignition circuit 174 can be switched off.

: The electrical control circuit for the blower also includes nor a flame check switch 187 (Fig. 3) on the about 66 ° Celsius is set and is attached above and behind the opening 55 and in series with the switches 168 and 171 and the solenoid valves of the burner. This switch is normally closed and is activated when the draft is reversed, thus preventing the flame from flashing back.

The electrical control circuit for the fan also includes a normally closed and manually adjustable one Thermal switch 125 (Fig. 9) which is in series with the switch. This switch includes contacts 126 and 127, which are at a predetermined temperature of, for example, 730 ° Celsius and prevent the device from overheating. Dia contacts 126 and 127 can be reset with a reset button to be closed again.

At room temperature it is set to around 510 ° Celsius

Thermal switch 177 closed and the burner also works

maximum output, for example with 30,000 British heat $ & units per. Hour until the temperature at this j Thermostat switch reaches a value of 510 ° Celsius. The thermostat switch then opens and switches winding 175 and reduces the output of the burner, for example to 25,000 British heat units per hour.

During normal combustion operation, the temperature in the device remains approximately constant until the entire | Waste is burned. The heat supply is then automatically interrupted, depending on the change in the Temperature in the combustion chamber. If all waste

- 19 -

is burned, the temperature rises very quickly to 620 to 650 ⁰ Celsius, for example. As a result, the contacts of a thermal switch I88 are closed and earth potential, ie low potential, is applied to the input 189 of the gate 137. Before the input was located 189 to + V, via the resistor 190. The output 191 of the gate 137 is connected to the input 192 of the gate 138 in conjunction _e The low level at the input I89 caused by the thermostatic switch _ 188 brings the multivibrator 137 * I38 to toggle, so that ® the output 142 of the gate I38 and thus also the input 156 of the gate 157 receive a higher potential. Since the input 155 remains at a lower potential, the output 158 has a higher potential. A higher potential at the input IbO and at the input 159 of the gate I6I generate a lower potential at the output 163 and this makes the transistor I65 non-conductive. The Brennar is turned off by opening the control circuit containing transistor 165. However, the motor 79 continues to run and generate drafts, thereby cooling the interior of the housing. This will etc. with minimal fuel consumption sin maximum efficiency Reach "because the control circuit] speaks automatically to the Respective waste, ie? K low loading the device operates shorter and by! 'Bigger load longer.

When the entire device has cooled to about 66 ° Celsius, the contacts of a limit thermostat switch close 193 and thus generate a low potential at the input 194 of gate 135 · The input 19 ^ was previously via the resistor 195 at + V voltage: located. The now at the entrance 19 ^ any lower level results from the resistor 196 and the capacitor 197 lying parallel to it. By closing the contacts of the limit thermostat switch 193 will also

ain input 198 of the gate I38 via a diode 199 the potential lowered. This input 198 was previously also at + V potential via a resistor 200. Through the Earthing of inputs 194 and 198 are both multivibrators tilted back and set a low potential at the output 159 of the gate 146, whereby the transistors I5I and 152 become non-conductive. The motor 79 is switched off (3 switched and the fan stops working.

The energy generated by the motor, which continues to rotate, after it has been switched off is dissipated by a diode 201 and a resistor 202, which are parallel to the motor 79. \ This discharge branch prevents a reverse | Voltage on transistors I5I and 152. After switching off the motor, the toilet is ready again to carry out the next burn cycle.

member., through which the voltage change at output 209 is converted into a pulse, by means of which the transistor 212 can be made conductive for a short time. The same process is achieved when the chamber doors are opened when using the Toilets are opened, with the tension shifting on the elements 203 to 205 in a control pulse at the collector of transistor 212 is converted.

The momentary conduction of the transistor 212 causes the input 198 of the gate 138 to be grounded or to a low potential, which means that the multivibrator 137, 138 assumes the position required to switch it on again, regardless of the point in time in the processing sequence Cover 2h has been opened. The collector of the transistor 212 is connected to a diode 199, which prevents the multivibrator 135 » 136 from tilting and the motor 79 from being switched off as a result of the momentary grounding of the input 198. However, as explained above, the same diode 199 enables the multivibrators 137 »138 together with the multivibrator 135 * 136 to be tilted depending on the thermostat switch 193 which is set to 66 ° Celsius.

The capacitors l67a, 189a and 19 ^ a are intended to prevent a switch-on surge at the assigned inputs 167, I89 and 19 ¹ V of gates 136, I37 and 135. It is also ensured that the switch 193 is not directly connected to earth, but that the parallel connection of a resistor and a capacitor is provided for this, then the contacts of the switch 193 remain closed until the temperatures in the toilet rise - when the input 19 ¹ V were directly earthed under these conditions, the multivibrator would not change its state when the cover switch I66 is closed

will. When the 66 ° Celslua limiter 193 opens, the resistor 196 serves as a discharge resistor for the capacitor 197 and the circuit is ready again for the next closing of the contacts,

Although the circuit was described in connection with the connection to the mains, the circuit can also be operated with direct current be fed, for example from a 12 V battery. A switch 104-106, I09-III, II3-II5, 117-119 and 177-181 provided. Additionally there are the contacts 213 to 218 are provided. These switching contacts are shown in the position intended for AC operation. They take the other switch position for oil direct current operation.

In the case of DC operation, the supply voltage is applied to the terminals 100 and 101 created. Terminal 101 is connected to a reference voltage, in this case to earth, via the closed switches 109 and 111. Terminal 100 is connected to the switch 125 in connection, namely via the © fuse 102, the interlocking switch 103 and the contacts 104 and 106. The Olelchspannung for operating the gates and transistors is in this So the case is tapped directly from the external voltage source. However, the ignition circuit is changed for DC operation. To get the high voltage necessary to ignite the gap 194 To generate, an oscillator with a transistor 220 is provided which, via the transformer 107, the resistors 221 and 222 and the capacitor 223 generates the desired high voltage.

When the relay contact 173 is ignited and thus closed, the Base of transistor 219 through resistor 224 and contacts 181, 179, 173, 176, 178, 106, 104 and switch 103

and the fuse 102 is connected to the input 100. The transistor 219 is thereby conductive and thus represents a Connection for the emitter of transistor 220; to earth via winding 112 and contacts 117 and 119. The direct voltage potential is also sent to the collector of transistor 220 through conductors 225, 124 and contacts 218 and 216. The same potential is applied to the base of the transistor? 20 is applied through the resistor 221 and the The emitter of transistor 220 is connected to the base of the transistor via winding 212, contacts 113 and 115 and the resistor 221 connected. The transistor 220 is therefore conductive and operated as an oscillator, so that now the secondary winding 112 acts as the primary winding and the winding 108 previously referred to as the primary winding serves as the secondary winding; The contacts 213 and 215 connect the capacitor 223 in parallel with Winding 108 and to ignition circuit 174. The left section of the Winding 112 and resistor 221 form a feedback circuit for transistor 220 so that it can oscillate. In this circuit, the transformer 107 thus acts as a translation trans formä tor, while in the case of Wechselspa-inungsbetireb as Reduction transformer worked. The spark plug can be fed with the high α alternating voltage generated in this way at the ignition circuit 174 and the spark required for ignition can be generated at gap 184. The burner is ignited and over the flame sensor 186 is the switch I85 then opened and the relay 172 switched off. This opens the contact 173 and the bias of removed from transistor 219 and so the oscillator off again * switched.
