Technical field

The present invention relates to the burning apparatus for combustion of liquid fuel of a kind of fan-type oil heater etc.

Background technology

Figure 84 is for schematically illustrating the clipped elevational cross-sectional view of fan-type oil heater one example in the past, and Figure 85 is its side view cutaway drawing, and Figure 86 illustrates the fuel feeding cover of oil feeding reservoirs and the cutaway view of receiver member.

Shown in Figure 84, fan-type oil heater in the past is, be provided with in the side, inside of its body P1 and inject in advance and store the oil feeding reservoirs P2 that liquid fuel P4 such as kerosene uses, supply with the liquid fuel P4 of sufficient quantity to the fuel tank P3 that is connected in this oil feeding reservoirs P2 below.

This liquid fuel P4 that is accommodated in fuel tank P3 is imported among the vaporizer P7 through sending oil pipe P6 by fuel force feed electricity consumption magnetic pumping P5.Owing to be arranged at the vaporizer heater (not shown) among this vaporizer P7, with the liquid fuel P4 vaporization of sending here.P9 is a fuel chambers, supports fixing combustion furnace P8 in its bottom.

Fuel by vaporizer 7 vaporization ejects well from the nozzle impetus, and together imports combustion furnace P8 with air that fuel is used and at the burning of flame hole P8a place, the air that heating flame chamber P9 is interior.And, shown in the arrow of Figure 85, go up the blowing fan P11 that installs by the fan electromotor P10 that is made of the single phase induction motor that is arranged at the body P1 back side etc., interior warmed-up air and the burning gases of the room air that sucks through filter P12 and combustion chamber P9 together blow out to indoor from blow-off outlet P13 as hot blast.

On the other hand, because the flame sensor P14 that the top slightly of flame hole P8a is provided with detects the flame current that is caused by combustion flame, when detecting to the flame current more than the preset value, to fan electromotor 10 energisings, thereupon, blowing fan P11 revolution blows out to indoor from blow-off outlet P13 as hot blast from indoor inhaled air.

At this moment, by detecting room temperature by room temperature thermistor P15, according to the temperature difference of room temperature and design temperature, the driving of control device (not shown) control fuel force feed electricity consumption magnetic pumping P5, the quantity delivered to vaporizer P7 of regulator solution fluid fuel P4 is by the firepower of combustion furnace P8 adjusting combustion flame.

Thereby, for example, if room temperature begins the operation of fan-type oil heater when low, then liquid fuel P4 is many to the quantity delivered of vaporizer P7, room temperature can sharply rise to design temperature, and the quantity delivered of regulator solution fluid fuel P4 stably maintains near the design temperature thereafter.

In addition, the supply of the fuel of oil feeding reservoirs P2 is, oil feeding reservoirs P2 is taken out from body P1, with turned upside down, the fuel feeding lid P16 with valve portion of oil feeding reservoirs P2 taken off, and injects fuel from base P17 (Figure 86).Confirming that fuel is after oil feeding reservoirs P2 supplies with, fuel feeding is covered on the threaded portion that P16 is screwed in base P17, for oil cap P16 under state put upside down and insert body P1, fuel feeding cap P16 is inserted among the receiver member P18 that is installed in above the fuel tank P3, be positioned on the fuel tank P3.

But, in fan-type oil heater in the past, owing in order to refuel, oil feeding reservoirs be taken out from body, in order to make the fuel feeding lid upwards to oil feeding reservoirs, oil feeding reservoirs is put upside down, after this external fuel is supplied with,, insert in the body in order to tighten the fuel feeding lid, need again oil feeding reservoirs to be put upside down on above-below direction, handle trouble.

And fuel feeding lid stubborn is combined into base and twists with screw thread and close, and exists because fuel feeding covers stubbornly closes insufficient oil feeding reservoirs fuel feeding when putting upside down that causes and cover the problem of fuel outflow.Particularly in astogeny society, cause screw thread to be twisted owing to grip is low low with joint efforts, and hope can improve it.

In addition, when fuel tank is supplied with fuel, because pasta rises to the valve portion of fuel feeding flap, displacement by air guarantees the stand oil face and supply with fuel in oil feeding reservoirs, the valve portion of oil feeding reservoirs is often drenched by fuel, when taking off the fuel feeding lid in oil feeding reservoirs refuels, exists deposited fuel on hand, skid when closing screw thread twisting, and flavoursome on hand and sordid problem.

Moreover, be accommodated in the occasion of DFF Direct Fuel Feed under the fan-type oil heater body internal state at oil feeding reservoirs, have the problem that fuel overflows in the oil heater body.

For this reason, the purpose of this invention is to provide a kind of have to the oil feeding reservoirs supply time, on above-below direction, do not put upside down oil feeding reservoirs, can non-cohesive on hand fuel, carry out fuel make up neatly, and can not carry out the burning apparatus for combustion of liquid fuel of the oil feeding reservoirs of fuel make up under the state in oil feeding reservoirs is accommodated in the oil heater body to oil feeding reservoirs.

To achieve these goals, burning apparatus for combustion of liquid fuel of the present invention is provided with and can be installed on intrinsic oil feeding reservoirs with freely taking out, have with the vaporization portion of fuel heating vaporization with the burning portion of the combustion furnace of the fuel combustion of vaporization, the fuel circulating pump that the fuel of oil feeding reservoirs is carried to vaporization portion, when oil feeding reservoirs is installed on the body, oil feeding reservoirs is connected in to burning portion and send jockey on the path of oil, discard the fuel tank of interim storage fuel below oil feeding reservoirs, the fuel of oil feeding reservoirs is directly supplied with to burning portion, even to the fuel make up of oil feeding reservoirs the time, do not put upside down also and can refuel.

In the burning apparatus for combustion of liquid fuel of said structure, owing to need not store the fuel tank of fuel, the fuel of oil feeding reservoirs is directly supplied with to burning portion, preferably be provided with and make the airport that does not produce the opening of negative pressure in the oil feeding reservoirs, if but under the situation that this airport opens wide, refuel move the time exist fuel outside case, to disperse and fuel leaks when the reversing oil feeding reservoirs may.

At this, in the present invention, in being used for oil feeding reservoirs, do not produce to be provided with on the airport of opening of negative pressure prevent the airport locking device that fuel dispersed and fuel can leak when fuel tank is inverted when case was moved outside case.

The 1st device as this airport of sealing, the inner face side that example is illustrated in airport is dispersed with fuel and is prevented that plate from surrounding, prevent that the plate side from forming the intercommunicating pore that is connected with airport in case to the extracting position just down from airport dispersing, the fuel when moving in the case is difficult for the structure of dispersing from airport.At this moment, if the bottom surface that prevents plate of dispersing tilts, put the formation intercommunicating pore at the deep-seated on its inclined plane, and form airport directly over the most shallow position, then depart from significantly the position in both holes, is preventing that effectively fuel is favourable on dispersing.

In addition, as the 2nd device in occluded air hole, but illustration by the scheme that in the guide member knee-action ground of the inner face side setting of airport, is loaded on the hammer on this guide member and between this hammer and airport, constitutes with the closure plate in occluded air hole along with the knee-action of hammer.When adopting this structure, exist when carton upside down, the hammer above-below direction moves, can be by the closure plate advantage in occluded air hole reliably.

At this moment, in order to move reliably and the guiding closure plate, as will making the R face, just can move reposefully by the R face of closure plate with the bight of the guide contacts side of closure plate.In addition,, roll on the conical surface by hammer, and the structure of knee-action then becomes a kind of compact structure, and the impulsive sound that produces along with the hammer knee-action also can reduce as adopting the bottom surface sections of hammering guide member into shape as the conical surface.

Utilize the airport locking device of above-mentioned hammer to be, oil feeding reservoirs (during carrying) airport when body takes out is become the device of opened state, but as the 3rd kind of airport locking device, the valve that has the occluded air hole as employing, the case valve rod that above-below direction shakes outside the case of this valve is housed, and the movable rod that this case valve rod is moved at above-below direction, when oil feeding reservoirs installs on the body, movable rod pushes the parts of base side and upwards moves, the case valve rod is shaken to the valve open sides, and, at oil feeding reservoirs when body takes off, the case valve rod moves the structure of shaking towards the valve closing direction down in the pressure of conducting oneself with dignity or spring causes, then at oil feeding reservoirs when body takes off, airport can be closed and when oil feeding reservoirs installed on the body, airport can become opening.

At this moment, when oil feeding reservoirs installs on the body, as has the airport locking device, then the airport by opening than the structure of function so early action of jockey in the footpath of sending oil circuit, just can open the abnormal pressure in the oil feeding reservoirs before jockey connects, flowing of fuel can be smooth and easy.In addition, be fetched into this when external at oil feeding reservoirs, the airport of case becomes closed state, thereby even carton upside down, fuel can not leak yet.

, can set for than the structure of sending oil circuit jockey directly will early move such function as the airport locking device, when oil feeding reservoirs is installed on the body, movable rod be contacted before the connection of the jointing portion of oil feeding reservoirs side with the parts of base side.As an example wherein, example illustrates in the vertical hole that will install in the movable rod opening easy on and off action ground in the jointing portion that is formed at the oil feeding reservoirs side, simultaneously, its lower end is outstanding downwards by jointing portion, when oil feeding reservoirs installs on the body, movable rod contacts with the bearing-surface of the plinth portion of burning portion side, can make the structure of movable rod knee-action before sending oil circuit directly to connect.At this moment, a part of structure (movable rod) of airport locking device is disposed in the jointing portion of oil feeding reservoirs side, becomes compact structure.

In addition, the oil-feed port of oil feeding reservoirs is owing to be in upwards state usually, and as the filter of the dust removed in the fuel etc. is set on oil-feed port, then dust or dust can not enter oil feeding reservoirs inside during fuel make up.

At this moment, filter forms cylindric, is set near the oil-feed port as the screen cloth part by fuel always, just can increase the area that passes through of fuel, also can prevent injection pump generation misoperation.In addition, as being provided with protuberance upwards, can between the bottom surface of the front end of the injection pump in inserting this filter and filter, produce the gap, the supply of fuel is carried out swimmingly in the bottom surface sections of filter.

In addition, as the hose guide spare of injection pump is set at the inner face of cylinder-shaped filter, the flexible pipe of injection pump is difficult to come off from filter, and during fuel feeding, the flexible pipe that can not make injection pump falls down and fuel takes place spills phenomenon from oil feeding reservoirs.

Screen cloth part for the filter side, as the screen cloth part that adopts water flowing be positioned at the top and the screen cloth part of not water flowing be positioned at the below structure, perhaps the screen cloth part of water flowing in the side and the screen cloth part of not water flowing in the structure of bottom surface, when oil feeding reservoirs refuels, the water of sneaking into can directly not enter in the case, can in filter, store, be convenient to the post processing of water.

In the aforesaid liquid fuel burner, adopted following structure, promptly, the fuel that is provided with the portion of spontaneous combustion in the future returns the oil return path of oil feeding reservoirs, the jockey of the oil return side that is connected with oil feeding reservoirs is set on this oil return path, but in such burning apparatus for combustion of liquid fuel, it is characterized by, the part of the pipeline of connection burning portion and oil return side jockey is shown length greatly and is provided with in the horizontal direction, and this approximate horizontal portion is as the function of the reservoir of interim storage fuel.

The present invention is in order to solve the problems of the technologies described above, discarded the fuel tank of interim storage fuel, the fuel in the oil feeding reservoirs is directly supplied with burning portion, the fuel feeding flap of oil feeding reservoirs can not drenched by fuel, simultaneously, the discarded desired various functions along with fuel tank are affixed on the oil feeding reservoirs.

Promptly, employing is used up situation for the fuel that at first early detects in the oil feeding reservoirs, be provided with the fuel quantity checkout gear of the fuel quantity that detects oil feeding reservoirs, perhaps being provided with the water checkout gear that detects the water that produces in the oil feeding reservoirs detects oil feeding reservoirs and whether installs to case installation and measuring device on the body, do not load onto the structure that then can not bring into operation as case to eliminate because of the structure of the water in the oil feeding reservoirs to the bad phenomenon of burning portion due to supplying with, perhaps to be provided with.

Fuel quantity checkout gear, water checkout gear and then the case installation and measuring device of this moment can be arranged on the arbitrary site of case, but as considering the rerum natura or the measuring ability of fuel and water, preferably is arranged on the structure of case bottom surface one side.

The amount detecting device that acts as a fuel, for example example show buoyancy aid with the carry magnet that is positioned at case inside and along with this magnet near and departure motion and be arranged on the structure of the reed switch that holds case platform side in the mode of ON or OFF.

As water checkout gear example show raingauge receiver ware with the electric conductivity on the case bottom surface that is arranged on electric conductivity for the water of storing dewfall, with this raingauge receiver ware electrodes in contact, with the oil feeding reservoirs electrodes in contact and make the raingauge receiver ware and the insulator of oil feeding reservoirs electric insulation, resistance value by being stored in water in the raingauge receiver ware and fuel poor is to detect the structure of water outlet.

The raingauge receiver ware preferably adopts the structure in the installing hole that forms and be installed to by electrical insulator the case bottom surface with the case split in order to improve the precision that detects water.Its raw material are made of conductive material, and are still, if use stainless-steel sheet, preferably antirust.

As electrical insulator, illustration between around the perisporium that is formed on the hole on the case bottom surface and the raingauge receiver ware, dielectric seal springy.The sealing part even also be difficult to storage of water after the draining, can prevent misoperation as implementing water-proofing treatment.

Consider from the electrode configuration, be preferably disposed on for example holding on the case platform of the case outside with raingauge receiver ware and case electrodes in contact respectively, so that raingauge receiver ware and case and each electrode contacting structure.At this moment, with raingauge receiver ware and the immediate position of case function as preceding termination electrode, the difference of the resistance value by the water stored around here or fuel is carried out the detection of water.In addition, be coated with dielectric coating, can detect water accurately by a part to the raingauge receiver ware.As the guiding device of guiding raingauge receiver ware is housed in the case side that the raingauge receiver ware is installed, then when from body, taking out case, can prevent to take place on the raingauge receiver ware damage or scratch phenomenon with fuel feeding.

Case installation and measuring device illustration for example be arranged on the microswitch that holds on case platform top or by being arranged on the magnet on the case bottom surface and holding the structure that the reed switch on the case platform constitutes.

At the input signal that passes through from these fuel quantity checkout gears, water checkout gear and case installation and measuring device, the occasion of control burning apparatus for combustion of liquid fuel, at control part, control out of service in the time of also can carrying out case installation and measuring device OFF (no case), drive empty control of burning the operational mode of vaporizer when perhaps, detecting equally to ON.In addition, case installation and measuring device is under the ON state, when the fuel quantity checkout gear that detects fuel quantity is OFF state (fuel is arranged), can be judged as the operation beginning, also can be controlled to bring into operation.In addition, case installation and measuring device is under ON (case the is loaded onto state) state, when the fuel quantity checkout gear that detects fuel quantity is ON state (no fuel), can be controlled to out of service, perhaps be under the ON state, also can be controlled to and inform fuel feeding to display part at the fuel quantity checkout gear.

The present invention is in order to solve the problems of the technologies described above, discarded the fuel tank of interim storage fuel, fuel in the oil feeding reservoirs is directly supplied with burning portion, the fuel feeding flap of oil feeding reservoirs can not drenched by fuel, simultaneously, for do one's utmost to reduce along with fuel tank discarded, may be stored in water in the oil feeding reservoirs and can send into burning portion one side and burning portion is exerted an influence, in combustion control loop, acceptance is from the signal of water checkout gear, the control of burning.

Promptly, the present invention have burning portion that the fuel of supplying with from oil feeding reservoirs is burnt, with the flame current value detect the flame detecting device of the state of flame in this burning portion and with the detected numerical value of flame detecting device, control the combustion control loop of previous combustion portion, be provided with the water checkout gear that detects the water in the oil feeding reservoirs, combustion control loop is not only accepted from the signal of flame detecting device but also accepts to control burning portion from the water detection signal of water checkout gear, sends into burning portion with the water that prevents to be stored in the oil feeding reservoirs.

As this water checkout gear,, utilize the difference of the resistance value of water and fuel to carry out water and detect preferably by at the 1st electrode in oil feeding reservoirs and be arranged between the 2nd electrode outside the oil feeding reservoirs and switch on.

Water detects and can read in combustion control loop all the time, but carries out water all the time when detecting, and as above-mentioned, detects owing to flow into weak current between electrode, and is charged easily on the case, can produce bad phenomenon such as get rusty.Therefore, wish that it is to carry out that water detects in official hour.

Flame detecting device and water checkout gear all are to electrifying electrodes, and to read the mode of its current value, the electrode of two checkout gears (earth electrode) is a common electrode, can interfere mutually, and therefore, when both moved simultaneously, accuracy of detection was not high.For this reason, as just any action in flame detecting device and the water checkout gear, can improve accuracy of detection.As the priority of this moment, consider from the combustion function aspect, should preferentially detect fired state.For this reason, in flame detecting device and water checkout gear, the preferably action of preferential flame detecting device is to read its current value.

Best, charged in order to prevent case, water only detects under burning is in the state of regulation and carries out.That is, preferably adopt combustion control loop only when fired state is in the state of regulation, the water checkout gear to be switched on, accept signal, remove in addition, preferentially judge fired state with the flame current value by flame detecting device from the water checkout gear.

At this, the state of regulation be meant operation stop in, stipulated time and aflame specified time limit after the operation beginning.Operation stops, and can not detect the flame of spontaneous combustion portion, and, the stipulated time after the operation beginning be pre-heat vapourizer during, can not detect the flame of spontaneous combustion portion.In addition, in the burning, during combustion stablized in, as only during regulation (relatively Duan time) carry out, two checkout gears are together moved effectively.

As between the water detection period, even in operation stops, from case after the discharge water, after case installs on the body, because of misoperation can take place for the existence of remaining water.In addition, because of the fuel of low temperature, box outer wall can dewfall behind the fuel feeding.At this, wish to avoid these stages and carry out the water detection.Promptly, be provided with and detect oil feeding reservoirs and whether install to case installation and measuring device on the body, in combustion control loop,, can prevent that sealing detects misoperation as loading onto signal and can not accept signal within a certain period of time from the case of case installation and measuring device by accepting from the water checkout gear.

As case installation and measuring device, example illustrates and is arranged on the microswitch that holds above the case platform, but also can adopt reset switch etc. on other members.

Detect the processing of information in combustion control loop as water, whether can carry out to burning portion output burning stop signal with and/or inform the control of display part.In addition, even also can carry out informing that at display part water detects, burning also remains on original state, when flame just weakens up to the arrival certain level, burning is stopped, to prevent the control of the misoperation that water detects.

Promptly, also can adopt in combustion control loop, in the burning, acceptance is during from the water detection signal of water checkout gear, read the flame current value from flame detecting device, this flame detected value is during greater than predefined flame value, and burning continues in the same old way, the flame detected value is in setting value when following, the control of ability burn-out.

In addition, as the water checkout gear, illustration have the raingauge receiver ware of the electric conductivity on the oil feeding reservoirs bottom surface that is arranged on electric conductivity for storage of water, the 1st electrode that contacts with oil feeding reservoirs, the 2nd electrode that contacts with the raingauge receiver ware and make the raingauge receiver ware and the insulator of oil feeding reservoirs electric insulation, by between two electrodes, switching on, poor by the resistance value that is stored in water in the raingauge receiver ware and fuel can carry out the structure that water detects.

The structure of control device

Figure 37 is the signal that comes according to water checkout gear 800 (Figure 32), flame detecting device 953 (Figure 34) and case installation and measuring device 900 (Figure 31), the pie graph of the control loop of the control of burning.In addition, of the present invention being characterized as in burning that flame detecting device 953 carries out control, owing to accept period that water detects etc.,, the quantity combusted checkout gear 750 that does not have direct relation among Figure 37 and Figure 38 is not with it illustrated in diagram for this reason.

As shown in the figure, control loop 950 is made of the microcomputer of built-in CPU, ROM and RAM, input side is connecting flame checkout gear 953, water checkout gear 800, case installation and measuring device 900 and run switch 954, and outlet side is connecting burning portion (comprising the load of vaporizer heater, electromagnetic pump, valve drive division etc.) 955 and display part 952, by various input signals, the control of burning.

Control loop 950 has acceptance and detects the water whether water is arranged from the signal of water checkout gear 800 and detect decision maker 961, acceptance is from the signal of flame detecting device 953, the flame standard comparison of flame current value and setting is detected decision maker 962 with the flame that detects fired state, the case whether acceptance is loaded onto with the evaluation case from the signal of case installation and measuring device 900 is loaded onto decision maker 963, accepts to export to burning portion 955 and display part 952 from the signal of these evaluation results and run switch 954 and timing measuring device 964 control part 965 of control signals.

Figure 38 is similarly its analog circuit figure.As shown in the figure, in this circuit diagram, by AC power AC through transformer TR supply power, by diode bridge DB with this power source full-wave rectification after, obtain the power supply of 24V power supply by the adjuster I C2 of 3 terminals.The 24V power supply after C4 is stable, is supplied with flame measuring staff 953 by electrolytic capacitor C5 and thin film capacitor C3, detects the flame current value by control loop (IC1) 950.In addition, according to this 24V power supply,, can obtain the 5V power supply through 3 terminal adjuster IC3.The 5V power supply is by electrolytic capacitor C8 and thin film capacitor C6, after C7 is stable, loads onto the power line of the microswitch 900 that detects usefulness to run switch 954 and case and supplies with, and can detect ON or OFF by combustion control loop (IC1) 950.

Closure plate 311 clogs airport B51, and the 316 one-tenth R faces in the periphery bight of end face become easily the shape in the medial movement of guide member 313.In addition, the periphery bight, bottom surface of closure plate 311 also can be the R face.

Guide member has the cylindric of the end for 313 one-tenth, for make roll hammer 312 within it the side bottom surface sections move, form the scalene cone 317 that central authorities become lower position, and form the hole of flowing through air 319 that connects in the bottom of the conical surface 317.In addition, form the screw 323 that is threaded with internal thread on the inboard that is positioned at pressing plate 310 in the outside of the upper side of guide member 313.The a plurality of grooves 318 that form on the conical surface 317 until the hole 319 of bottom is under the state of erecting at oil feeding reservoirs B12, become the path that flows through air from top.In addition, the angle initialization of the conical surface 317 become when oil feeding reservoirs B12 is inverted since the rolling of the hammer 312 that rolls and thereupon upwards moving of closure plate 311 and can close airport B51.

In said structure, when oil feeding reservoirs B12 is inverted, the hammer 312 that rolls rolls on the conical surface 317 of the bottom surface of guide member 313, and then roll in the side, roll hammer 312 to airport B51 side pushing closure plate 311, clog airport B51 by closure plate 311, thereby the fuel in the oil feeding reservoirs B12 can not spill from airport B51.

Oil feeding reservoirs B12 is when erecting state, the hammer 312 that rolls is positioned at by deadweight on the conical surface 317 of bottom surface sections of guide member 313, but by being formed at the groove 319 on the conical surface 318, with the hole 319 of oil feeding reservoirs internal communication and airport B51 and become connected state, thereby can not become negative pressure in the case.

In addition, as the 3rd embodiment of airport opening closure (D52), be whether to install on the body, so that airport B51 becomes the opening and closing state by oil feeding reservoirs B12.Promptly, airport opening closure D52 is shown in Figure 49～Figure 51, but valve 330 with airport B51 of free switch ground sealing oil feeding reservoirs B12, load onto the case valve rod 331 of valve 330, the bowl cover 332 of containing box valve rod 331, can make the movable rod 333 of case valve rod 332 knee-actions, to the bar spring 334 of movable rod application of force about in the of 333.

Case valve rod 331 is, it is Z-shaped with the function as fulcrum 336 that valve 330 installation portions are divided into protuberance 335, distolateral, and the other end forms and movable rod 333 engaging hole engaged 337.Conjugate foramen 337 becomes some vacant shapes when engaging with movable rod 333.

Bowl cover 332 has the recess of containing box valve rod 331.One end of this recess is open, and other end side seal closes, with the fulcrum 336 supporting slotted openings 338 that form bar 331.Be provided with the buffer bar 120 of fixedly connected connector portions B47 (Figure 49) at an end of the open sides of recess.

Movable rod 333 makes case valve rod 331 knee-actions, and in the vertical hole portion 340 that runs through that the central authorities of the joint body B55 of the B47 of jointing portion form, thereby can move at above-below direction.

Front end about valve 330 has in the airport B51 of oil feeding reservoirs B12 is the valve body 341 of pin type, and the sealing pad 343 that installs to the bottom of this pin portion.In addition, airport B51 is formed at the top of sphere portion 343, sphere portion 343 be formed at highlightedly laterally oil feeding reservoirs B12 above.

In said structure, air seal device D52 is installed on the B47 of jointing portion, in the central longitudinal of this joint body B55 in hole portion 340, insert the movable rod 333 that is embedded with pole spring 334 from the below, in addition, the Z-shaped fulcrum 336 of case valve rod 331 is inserted in the slotted opening 338 of incorporating section of bowl covers 332, the upper end of movable rod 333 is blocked by another distolateral hole 337 of quick nut and case valve rod 331 and only is assembled together.

When installing to oil feeding reservoirs B12 on the body B1, when the following gluten portion of the lower end contact base 350 that installs to the movable rod 333 on the B47 of jointing portion of oil feeding reservoirs B12 and the seal joint 103 of the jointing seat portion 100 of combustion side contacts, push by muscle portion, make upwards action of movable rod 333, thereupon, case valve rod 331 also upwards shakes, install to the also upwards prompting simultaneously of valve 330 on the case valve rod 331, thereby between the airport B51 of the sphere portion 343 of valve 330 and oil feeding reservoirs B12, produce the gap, air flows in the oil feeding reservoirs B12 from airport B51, presses to common atmospheric pressure state (Figure 51) in the oil feeding reservoirs B12.

At this moment, for with the B47 of jointing portion of oil feeding reservoirs side with before the plinth portion 100 of burning portion side is connected, the movable rod 333 of airport opening closure D52 must contact with the last gluten portion of the seal joint 103 of plinth portion 100, so that airport B51 becomes open state, by setting position relation up and down, just in case the oil feeding reservoirs internal pressure is under the higher state, even be connected, also can prevent the troubles such as leakage that jockey produces with body.

In addition, during from body B1 taking-up oil feeding reservoirs B12, the last gluten portion that installs to the seal joint 103 of movable rod 333 and the jointing seat portion 100 of combustion side on the jockey of oil feeding reservoirs B12 contacts and opens, under the elastic force effect of pole spring 334, movable rod 333 is forced downwardly action, thereby install to valve 330 on the case valve rod 331 also simultaneously to sinking, make airport D51 become out the valve state.Therefore, air can not flow in the oil feeding reservoirs B12 from airport B51, and even oil feeding reservoirs B12 is inverted, the fuel in the oil feeding reservoirs B12 can not overflow yet.

In addition, the sphere portion 343 that forms airport B51 is difficult for accumulating dust or dust owing to make progress into protuberance, does not have the long-time trouble of using.

Next, the 4th embodiment such as Figure 49 of airport shutoff device (E52), Figure 52, shown in Figure 53, airport B51 is formed on the bottom of the concave surface portion 348 on be formed at oil feeding reservoirs B12, but the valve 330 that this airport B51 is closed on free switch ground is that the valve body 345 of pin type and the bottom that installs to this pin portion constitute with the O type ring 346 that seals usefulness by the front end in the airport B51 of oil feeding reservoirs B12 up and down.Other structures are identical with the 3rd embodiment.

In said structure, sky is opened 348 one-tenth downward recesses of concave surface portion of airport B51, is easy to accumulate dust or dust, but because the pin portion knee-action of the front end of the valve body 345 of valve 330, removed dust or dust, thereby dust or dust can not influence the switch of airport B51.In addition, the formation of concave surface portion is compared with the formation of the sphere portion of the convex of the 3rd embodiment, has the simple advantage of die structure.

In the above-mentioned the 3rd and the 4th embodiment, be to adopt pole spring 334 case valve rod 331 being forced apply towards the power of valve closing direction, but also can be without pole spring 334, but the method for only utilizing the deadweight of case valve rod or movable rod 333 to come valve-off.In addition, airport shutoff device D52 the 3rd and the 4th, among the E52, but movable rod 333 easy on and off action ground run through among the B47 of jointing portion, employing is when oil feeding reservoirs installs on the body, the structure in open air hole before jockey connects, simultaneously, these members are arranged on same place, can make the device compactness, also the airport shutoff device can be arranged on the place different, with the structure in open air hole before jockey connects with jointing portion.At this moment, the contact position of movable rod can be arranged to miscellaneous part and contact with the jointing seat portion of base side.

The structure of jointing portion

Figure 56 is the cutaway view that the joint B13a that send oily side of jointing portion is shown, Figure 57 is the decomposition diagram under the siphon pipe B20 connection status that illustrates with its case side, Figure 58 is the cutaway view that the joint B17a of oil return side is shown, and Figure 59 is the decomposition diagram under the pipeline B63 connection status that illustrates with its case side.

As shown in figure 49, the B47 of jointing portion of case side is to send the jointing B13a of oily side and the jointing B17a of oil return side to be integral.Each jointing B13a, B17a such as Figure 56 shown in Figure 59, have joint body B55, valve system B56, valve guard B57, the base end side flange B55d (Figure 56) of each body B55 interconnects and is integral.The B47 of this jointing portion is arranged among the recess B 12g (Figure 48) on the right front bight that is formed into oil feeding reservoirs B12 side, by joint pressing plate B54, through pad B53, is fixed to by screw B54f on the bottom surface of recess B12g of oil feeding reservoirs B12.

Each joint body B55 such as Figure 56, shown in Figure 58, by the cylindric barrel B55a of front, from the protuberance B55e of each barrel B55a to the side-prominent tubulose of oil feeding reservoirs, the synthetic resin that B55f and the base end side flange B55d that stretches out to the radial direction outside in the centre of this protuberance B55e constitute is made, two jointing B13a, the base end side flange B55d of B17a interconnects and is integral.

On barrel B55a, tubular tapering (sealing surface) B55b that slowly attenuates downwards from its bottom is with the cylindrical portion B55c that keeps specific length with specified diameter forms as one continuously in the lower end of this tapering B55b, and inside is provided with valve system B56.

In be loaded on each valve system B56 on the tubular barrel B55a by sending oil circuit footpath B from oil feeding reservoirs B 12 to electromagnetic pump B14, be used for freely cutting off with closing oil return path C from vaporizer B15 to oil feeding reservoirs B12, valve B 59 and valve body usefulness O type ring B60 and valve body spring B 61 formations.

Valve B 59 becomes and the shaft-like interior shape of barrel B55a, the tapering B55b of joint body B55 and cylindrical portion B55c similar shapes roughly, and becomes in the reciprocating shape in the internal freedom ground of joint body B55.Promptly, valve B 59 has and roughly becomes cone shape spigot (sealing surface) B59b, be connected with the lower end of spigot B59b, thinner and be the movable part B59a of long column shape than cylindrical portion B55c, in the taper part of spigot B59b, the O type ring pad B60 of ring-type is arranged to and can contacts with the tapering close shape of B55b pivot of joint body B55.

For the leaving and contacting of the tapering B55b that controls spigot B59b and body B55, the length setting of movable part B59a becomes closely connected in the O of spigot B59b type ring pad B60 and tapering B55b inside and closes under the valve state length that front end is more outstanding than cylindrical portion B55a.

Valve guard B57 forms the annular recess of acceptant valve body spring B 61 by the hole on the top of the airtight tubular barrel of O type ring B58 B55a in its inside.

Install in the valve body spring B 61 on the barrel B55a, between the valve guard B57 on installing to and the spigot B59b of valve B 59, valve B 59 is applied towards the power of closing the valve direction.

Base end side flange B55d for two joint B13a, B17a links into an integrated entity, radial direction extend be arranged to roughly rectangular tabular, outer embedding of the joint gasket B53 of ring-type and closely connected inboard to flange B55d, can prevent fuel from protuberance B55e, spill around the B55f.

The protuberance B55e of case side, B55f forms tubulose, and the part also more inboard than base end side flange B55d inserted inboard from the opening B64 on the tank wall that is formed at oil feeding reservoirs B12, and its internal path is connected communicatively with the front end of siphon pipe B20 or return duct B63.The horizontal plane of this internal path will be positioned at than the horizontal plane of the full liquid of fuel of oil feeding reservoirs wants eminence, makes that the fuel in the case can optionally not flow among the barrel B55a.

Protuberance B55e, the internal path of B55f such as Figure 56, shown in Figure 58, setting for can embedded this siphon pipe 20 or the diameter of return duct B63, distolateral in the case midway from path, formation can embedded tubulose fixed part than major diameter, this than larger-diameter path B55q and outside can locate the thin-walled pressure vessel stiffening bead pressing part B20a of siphon pipe B20 or return duct B63 on the stage portion B55r between the distolateral path path B55s, B63a (Figure 57, Figure 59).Path path B55s (Figure 58) is communicated with the valve chamber of barrel B55a.

Protuberance B55e, the medial end of B55f is along forming the slotted opening B55g that radial direction connects, and B55m sets for and can utilize its elasticity hole enlargement.This slotted opening of clamping B55g, the pipe inner peripheral surface of the both sides of B55m form can with siphon pipe B20 or return duct B63 only pull out the insertion groove B55j that part B 65a engages, B55n (Figure 59 (b)).

In addition, shown in Figure 57, the case inside dimension of sending the case inside dimension of the protuberance B55e of oily side can set the protuberance B55f (Figure 59 (a)) than oil return side for is short, with easy connection siphon pipe B20.

Siphon pipe B20 forms the font of falling L, and its upper horizontal portion is connected (Figure 41) with sending oily joint B13a, and the vertical component effect lower end arrives the bottom surface of oil feeding reservoirs B12 always, and is connected with suction inlet B66 (Figure 60) in order to suct the fuel among the oil feeding reservoirs B12.The horizontal part front end of siphon pipe B20 forms with when the B47 of jointing portion is connected, and locatees the thin-walled pressure vessel stiffening bead pressing part B20a (Figure 57) of the flange-like that O type ring uses.

The protuberance B55f (Figure 59) of oil return side is longer than the protuberance B55e (Figure 57) that send oily side, and forms slotted opening B55k, B55m down thereon.Slotted opening B55k up and down, among the B55m, the slotted opening B55k of upside sets for bigger than downside slotted opening B55m, internal diameter is bigger slightly than the external diameter of return duct B63, when inserting return duct B63 in the inboard, the thin-walled pressure vessel stiffening bead stamped groove B55n that forms toward the outer side and end with the thin-walled pressure vessel stiffening bead pressing part B65a card of tubulose fixed part B65.

Return duct B63 is owing to be that the fuel from vaporizer B15 is returned oil feeding reservoirs B12, thereby becomes the L font in oil feeding reservoirs B12 inner bending, and its pipe outlet B63b is configuration upwards.Even because of temperature difference, under the state of the fuel abnormal ascending in the oil feeding reservoirs B12, return duct B63 also becomes pipe outlet B63b from the state that the fuel level in the oil feeding reservoirs B12 projects upwards, and can prevent the phenomenon that fuel goes out in the side leakage of burning portion accidentally.

As making siphon pipe B20 or the return duct B63 can not be from protuberance B55e, the fixture that comes off among the B55f, the section that is provided with shown in Figure 57 and Figure 59 is C font tubulose fixed part B65.The outer surface of tubulose fixed part B65 form can with protuberance B55e, the inner face insertion groove B55j of B55f, the thin-walled pressure vessel stiffening bead pressing part B65a of the flange-like that B55n engages forms slotted opening B65b in one direction, and its internal diameter is set for slightly littler than the external diameter of siphon pipe B20 or return duct B63.

In addition, the raw material of joint body B55 are not limited to resin, can be metal, and in addition, the section configuration of tapering B55b, cylindrical portion B55c etc. etc. also is not limited to circle.

The B47 of jointing portion is fixed to joint pressing plate B54 on the oil feeding reservoirs B12 shown in Figure 56, is formed on the incision that lateral incision erects on the mediad of metallic plate and erects sheet B54a.This incision erects sheet B54a from upside pushing jointing B13a, the valve guard B57 of B17a, and be not held in and can from barrel B55a, extract.Erecting central authorities that the incision of sheet B54a erects in this incision forms and connects jointing B13a, the protuberance B55e of B17a, the discharge orifice B54b of B55f, become the periphery pushing B54d of the portion pushing jointing B47 of portion periphery, band muscle B54c around this discharge orifice B54b, and, the pushing B54e of portion of central authorities, prolongs between the B17a at two jointing B13a from the downside central authorities of discharge orifice B54b.

The base end side flange B55d of the periphery pushing B54d of portion and central pushing B54e of portion and the B47 of jointing portion together is fixed on the oil feeding reservoirs B12 with screw B54f.In addition, by discharge orifice B54b and the central pushing B54e of portion, can prevent that the position about the B47 of jointing portion from staggering.

The B47 of this jointing portion as shown in figure 49 because when oil feeding reservoirs B12 was inverted, the B47 of jointing portion did not contact with miscellaneous part, being covered with section above oil feeding reservoirs B12 is the buffer bar 120 of L font.The outside of this buffer bar 120 is smooth spigot surface 120a; spigot surface 111a (the Figure 65 that forms on the face-off face mutually with the guard bar 111 (Figure 68 (b)) of the covering air valve B18 (Figure 66) of jointing seat portion 100; Figure 66) butt joint; when installing to oil feeding reservoirs on the body, as the guide member effect.

On the connecting portion of suction inlet B66 (Figure 60) side of the vertical component effect lower end of siphon pipe B20, also become the thin-walled pressure vessel stiffening bead pressing part identical, and be connected with suction inlet B66 with the connecting portion of jointing portion.Suction inlet B66 is roughly cylindric, and the lower end has a plurality of legs, the bottom process simultaneously and in be connected to the gauze filter B66a that stainless steel is made, face-off form to connect a pair of slotted opening B66b that siphon pipe B20 uses up, its upper end is connected with siphon pipe B20.

Suction inlet B66 installs to the hole portion of the suction inlet fixed head B67 of oil feeding reservoirs B12 shown in Figure 60, not removable, and the inwall in suction inlet B66 and the oil feeding reservoirs B12 does not collide.

In said structure, the order that the B47 of jointing portion and siphon pipe B20 and return duct B63 are assembled on the oil feeding reservoirs B12 is, punch process oil feeding reservoirs left part spare and right members B12a, behind the B12b (Figure 48), before the following process that engages oil feeding reservoirs left part spare B12a and right members B12b, (Figure 56 Figure 58) is abutted against a pressing plate B54 and screw the B47 of jointing portion is fixed on the assigned position of oil feeding reservoirs right members B12b by pad B53.

At this moment, the valve guard B57 of joint is because the incision by joint pressing plate B54 erects the sheet B54a pushing that makes progress, and the incision of valve guard B57 by joint pressing plate B54 erects sheet B54a and be not held in and can fly out from the B47 of jointing portion.

On the recess B40n of the inside of the housing recess B40a that is formed at monitor station B40, the reed switch B79 near switch of the amount detecting device B69 that acts as a fuel is housed.

The electrode B 72 of water checkout gear B68, B73 is made of electrode stem 115.This electrode stem 151 is shown in Figure 71 (a), the stainless-steel sheet that will have elastic force bends to step-like, the insertion seat 151a of the wire socket of root go up to form monitor station fixedly usefulness screw hole 151b and be formed on than and the support holes 151c on the front, front end upwards is bent into the L font.

Installing the monitor station B40 side of this electrode stem 151, bar is installed with boss B40q outstanding downwards, and forms on this boss and fixingly use hole B40p, in addition, near this installation portion, the support B40h of the fulcrum that becomes bar 151 knee-actions of tab-like circular convex.

The installation method of electrode stem 151 is, on the support B40h of monitor station B40, electrode stem 151 inserts among its receiving orifice 151c, and the screw hole 151b of bar 151 is alignd with the installing hole B40q of monitor station B40, is fastened on the boss B40p by screw.So, the front end of electrode stem 151 is from square hole B40d, and B40e is to the face side perk.In order to limit the size of this perk, the outstanding reinforcement B40m that forms in the inside of monitor station B40.So, in the electrode stem 151, the fixed part of its root is different with the swing fulcrum, can not concentrate at the fixed part upper stress, can obtain favorable durability.

Case installation and measuring device B70 is arranged on the rear side of monitor station B40, shown in Figure 61, has the case check-out console 117 that is fixed on the monitor station B40 rear side, can be installed to the bar 113 that contacts swing on this check-out console 117 and when oil feeding reservoirs B12 installs on the body, with the oil feeding reservoirs bottom along the vertical direction with freely swinging, contact the switch that leaves and ON, OFF mode are installed to the microswitch 112 (Figure 71 on the check-out console 117 by the knee-action by this bar, Figure 73), the pole spring 116 of application of force when movable and to bar 113.

Bar 113 is in a narrow margin the member for the L font overlooked, and forms wheel hub 113b as the revolution fulcrum at the one end, and the other end becomes case side-prominent to monitor station B40 from case check-out console 117 and that accept the oil feeding reservoirs casing and accepts face 113a.

Case check-out console 117 is bent into the member of コ font for plate-shaped member, the installation of the axial region 117a that forms mounting rod on its wall face, microswitch 112 with housing recess 117b and when the case of bar 113 is accepted the face knee-action with the movable roughly the same square hole 117c of width.

The upper plate of the two ends of pole spring 116 and case check-out console 117 and bar 113 cards end, and bar 113 is applied towards making microswitch 112 in the power of connecting (ON) direction.

Above-mentioned installation and measuring device B70 is assembled into, after card ends in pole spring 116 insertion rods 113, the case bearing-surface 113b of bar 113 is led among the square hole 117c of case check-out console 117, afterwards, one distolateral hub portion 113b of bar 113 is inserted among the axial region 117a of case check-out console 117, fix by fast pulley.And, microswitch 112 is inserted on the pin of housing recess 117b of case check-out consoles 117, fix and finish assembly work by fast pulley.

The action of this case erecting device B70 is, when oil feeding reservoirs B12 installed on the body B1, the case bearing-surface 113a of bar 113 was pressed to the below by oil feeding reservoirs B12, thereby makes microswitch 112 become open state, and the loop becomes connection (ON) state.On the contrary, when oil feeding reservoirs B12 did not install on the oil feeding reservoirs B12, the case bearing-surface 113a of bar 113 upwards promote under the effect of pole spring 116, thereby microswitch 112 became closed state owing to do not accept oil feeding reservoirs B12, and the loop becomes disconnection (OFF) state.

Like this, because the travelling contact that has adopted microswitch 112 becomes open state, and become the using method of closed state when case takes off when case is loaded onto, tolerance increase in the stroke up and down of oil feeding reservoirs B12, when microswitch 112 moves, the incidence of fault reduces.

In addition, pass, position for the fuel level in the oil feeding reservoirs B12 and each jockey is, the B47 of jointing portion at oil feeding reservoirs B12, suct full water that path B55p (Figure 56) that the fuel among the oil feeding reservoirs B12 passes through is positioned at oil feeding reservoirs B12 and show the top of liquid level, can avoid the fuel leakage phenomenon in the case connecting portion of the B47 of jointing portion.

In jointing seat portion 100, the next door 98i upper end of the lifting path 98d (Figure 68) of air valve B18 below is set in the top of the fuel level in the oil feeding reservoirs B12.At this, the fuel level in the oil feeding reservoirs is generally the liquid level position that full water shows.

In addition, fuel in oil feeding reservoirs B12 is because of temperature difference, when the liquid level abnormal ascending, the B47 of jointing portion also sets unusual liquid level height than the fuel in the oil feeding reservoirs B12 from vaporizer B15 side for towards the pipe outlet B63b of the oil return pipe B63 of oil feeding reservoirs B12, thus can prevent fuel from the oil feeding reservoirs side by the oil return line phenomenon returned of vaporizer B15 side radially.At this moment, even owing to send into electromagnetic pump B14 side from the B47 of jointing portion, pump B14 also can stop, not further transfer the fuel.In addition, the position of the airport B18f of air valve B18 is set for usually than unusual liquid level and is also located the top, thereby fuel can not pass through air valve B18 to external leaks from oil feeding reservoirs B12.

In jointing seat portion 100, the upper end of the next door 98i of the lifting path 98d of air valve B18 below is owing to the common liquid level that is usually located at than oil feeding reservoirs B12 is also located the top, when fire extinguishing, open air valve B18 is to send into air oil circuit when footpath, the path area 98d1 of the oil feeding reservoirs side of lifting path 98d is bigger, thereby but fuel fast return oil feeding reservoirs side can be blocked the supply of fuel reliably.

The formation of control mounting

Figure 74 is for by from the signal of fuel quantity checkout gear B69, water checkout gear B68 and the case installation and measuring device B70 pie graph with the control loop of controlling various operational modes.As diagram, control part 141 is made of the microcomputer 141 of built-in CPU, ROM and RAM, input side is connected with fuel quantity checkout gear B69, water checkout gear B68 and case installation and measuring device B70, outlet side drives loop 118, display part 149 and valve driving loop 119 with electromagnetic pump and is connected, and moves control by various input signals.

For example, in service, by pulling out oil feeding reservoirs, case installation and measuring device B70 detects when being OFF (no case), import its signal, when the signal that electromagnetic pump B14 is stopped to drive loop 118 outputs to pump, the clearing signal of air valve B18 is driven loop 119 outputs to valve, stop with the control operation, perhaps, equally, when case installation and measuring device B70 detected to ON, also the control driving was burnt the empty sky that burns of vaporizer B15 and is cleaned operational mode.

The action of fan-type oil heater

Below, the action of the fan-type oil heater of above-mentioned formation is described.When the fuel change among the oil feeding reservoirs B12 was empty, with the lid B4 unlatching of body B1, hand-held handle B43 took out oil feeding reservoirs B12, is positioned at handle B43 under the state of upside, takes off locking device B19, from the oil-feed port B44 supply fuel of oil feeding reservoirs B12.At this moment, oil feeding reservoirs B12 is in upside at handle B43, places flat place to carry out supply, thereby needn't put upside down oil feeding reservoirs B12 about, the phenomenon of fuel feeding lid that such in the past fuel is made oil feeding reservoirs B12 dirty can not take place, can carry out the supply of fuel simply, reliably.

After fuel feeding finishes, the case lid B4 of body B1 is opened, the oil feeding reservoirs B12 that enters fuel is set on the position of regulation.At this moment; the below of buffer bar 120 of the B47 of jointing portion that is attached to oil feeding reservoirs B12 is along the outside of the air valve over cap 111 of the jointing seat portion 100 of burning portion side; import the below of jointing seat portion 100; and then the B47 of jointing portion of oil feeding reservoirs B12 side is connected (Figure 75～Figure 78) with the plinth portion 100 of burning portion side.

At this moment, in the oily side connector B13a of sending of the B47 of jointing portion, its valve B 59 is being directed inserting among the hole 103a of the seal joint 103 that send oily side joint headstock B13b, and enters among the hole 102a that connects seal 102, and 98a contacts with valve seat.At this moment, connect the body cylindrical portion B55c close encapsulation of the hole 102a of seal 102, thereby fuel can not spill from this connecting portion by the B47 of jointing portion.

In addition, when oil feeding reservoirs B12 inserts among the body B1, pushed by valve seat 98a, send the valve B 59 of oily joint B13a to move up, make 61 one-tenth compressive states of valve body spring B, 59 one-tenth opening of valves states of valve B become open state from the siphon pipe B20 of oil feeding reservoirs B12 through the oil circuit footpath B that send that jointing B13a flows into electromagnetic pump B14 side.

Equally, the joint B17a (Figure 58) of the oil return side of oil feeding reservoirs B12 moves too, the valve B 59 of jointing B17a is being directed inserting among the hole 103a of seal joint 103 of jointing seat portion 100, enter among the hole 102a that connects seal 102, the valve B 59 of oil return side connector B13a contacts with the valve body 106 of the valve system 105 of seat body B98.At this moment, the body cylindrical portion B55c that connects seal 102 and the B47 of jointing portion is closed sealing, makes fuel can not leak.

In addition, when oil feeding reservoirs B12 inserts among the body B1, the seat valve body 106 of valve system 105 (Figure 67) moves down, contact with 108 ends of seat body cap at recess 108a place, afterwards, the valve B 59 pushing seat valve bodies 106 of back leakage connection B17a move up, and make 61 one-tenth compressive states of valve body spring B, and 59 one-tenth opening of valves states of valve B.Thus, become open state from vaporizer B15 through the oil return path C that pipeline B23 returns oil feeding reservoirs B12 side.

Oil feeding reservoirs B12 is installed on the body B1, when the bottom surface of oil feeding reservoirs B12 arrives the monitor station B40 of the bottom that is in receiving room 4a, the postero lateral arm contact-making surface B50d of the case foot section B50 of oil feeding reservoirs B12 presses down case installation and measuring device B70 (Figure 69, the bar case bearing-surface 113a of bar 113 Figure 73) makes 112 one-tenth ON states of microswitch in the loop.

Under oil feeding reservoirs is loaded onto state, the run switch (not shown) of operation fan-type oil heater, when power supply is in ON, because air valve B18 is opening under erasing state, in case drive electromagnetic pump B14, air just enters from the airport B18f (Figure 68 (b)) of air valve B18, and sends among the B of oil circuit footpath.For this reason, the fuel among the oil feeding reservoirs B12 can not be sucted by siphon pipe B20, and is opposite, remaining in the fuel that send among the B of oil circuit footpath sends among the vaporizer B15, simultaneously, together return the oil feeding reservoirs B12 from oil return path C with the fuel that remains among the vaporizer B15, thus can residual fuel in the path.

In vaporizer B15, during run switch ON, the vaporizer heater is heated, and vaporizer B15 is preheating to the temperature of regulation.When reaching the temperature of preheating end, to air valve B18 energising, solenoid B18d excitation, valve B 18g moves towards the direction with airport B18f sealing, stops air and enters from airport B18f.So, the oil circuit footpath B that send that is flowed into electromagnetic pump B14 by oil feeding reservoirs B12 through jockey becomes connected state, and the fuel in the oil feeding reservoirs B12 is sent among the B of oil circuit footpath.

In vaporizer B15, the fuel of sending into by electromagnetic pump B14 becomes the gas shape of vaporization, mixes with gas in the combustion furnace from the combustion air of nozzle B 31 ejections of vaporizer B15, sprays from the flame hole 16b of combustion furnace B16, in this flame hole 16b place igniting, with in combustion chamber B30 internal combustion.At this moment, poor according to room temperature thermistor 11 detected room temperatures and the design temperature of setting by operating portion B3, control part 141 (Figure 74) control electromagnetic pump B14 action changes the amount of sending into the liquid fuel among the vaporizer B15, suitably regulates the caloric value that burning causes thus.

After taking fire, it is predefined current value when above that flame sensor B36 (Figure 42) detects flame current, not shown fan motor energising, and Air Blast fan B9 revolution, air is inhaled into indoor.In addition, the speed of gyration of fan motor is by control part 141 controls.The room air that sucks is captured the radiant heat that is obtained in the B30 of combustion chamber, together blow out to indoor as Wen Fengcong blow-off outlet 2 with burning gases, and the control temperature rises indoor temperature.

When the operation of body B1 stopped, the driving of electromagnetic pump B14 stopped, and simultaneously, air valve B18 is open, and air can stop the supply with fuel shutoff reliably from outside access path.
