On the gas supply pipe 46 that is installed on gas hose 22 downstreams, 2 electromagnetic switch valves 47,48, electromagnetic proportional valve 49 sequentially are installed from upstream side. Electromagnetic switch valve 47,48 and electromagnetic proportional valve 49 are connected in controller 62.Electromagnetic switch valve the 47, the 48th, built-in solenoidal switch valve is opened during energising and is made the gas-flow mistake, closes fuel gas path during power failure.Electromagnetic proportional valve 49 is along with electrical current increases the proportioning valve that aperture becomes big style, has the proportional characteristic of gas-flow flux and galvanization.
The reducing diameter part 44a that is inserted into conduit 44 at the nozzle 46a of gas supply pipe 46 front ends formation fixes.
The burning control part 62a of controller 62 carries out the burning control of burner 39 according to command signal, the detection signal from temperature sensor 51 and thermocouple 43, control electromagnetic switch valve 47,48, electromagnetic proportional valve 49, the ignitor 42 of the switch 54 that turns round with room temperature configuration switch 55.Blower fan control part 62b is according to from the command signal of running switch 54 and room temperature configuration switch 55 with from temperature sensor 51, thermocouple 43 revolution with the detection signal control electro-motor 36 of tachometer generator 35.
Safety verification/timer portion 62 is checked safety verification that the function of pressure fan 34 and thermocouple 43 is carried out and from concerning between the running pent moment of switch and timer whether the unlatching of the switch 54 that turns round is that the user operates before igniting beginning.
After the running switch 54 of operation combustion gas dim wind warming machine 10, to lighting a fire or check out action under the situation that begins unusually and not to light a fire, describe with the flow chart of Fig. 5.
If open running switch 54 (S14), as shown in Figure 5, controller 62 is accepted this signal, according to carrying out the starting of electro-motor 36 and the outgoing inspection of thermocouple begins safety verification (S18) by safety verification/62c of timer portion is actual.The starting inspection of electro-motor 36 is by to electro-motor 36 input action signals, confirm by the revolution of tachometer generator 35 detected electro-motors 36 whether setting with on carry out.The starting inspection of this electro-motor 36 can be with ventilation in the air-supply conduit 32 that carries out before igniting beginning, prevent just in case the removing that has combustion gas to be detained is turned round carries out in the lump.Whether the output voltage of the outgoing inspection of thermocouple 43 by check confirming thermocouple carries out in the prescribed limit of the temperature in the contemplated combustion barrel 38 before corresponding to the burning beginning.
And this safety verification also can carry out like this: import analog signal to burning control part 62a, blower fan control part 62b or safety verification/62c of timer portion, whether the output signal by checking processed result is setting, confirms whether its function is normal.
In ensuing S22, distinguish whether safety verification ends.Safety verification under the situation about not ending (NO), and standby to safety verification is ended.Under the situation that safety verification is ended (YES), ensuing S26 divides a word with a hyphen at the end of a line.
In S26, distinguish running switch 54 whether by the timer starting of user's operation, in ensuing S30, distinguish that running switch 54 opens or cut out.Under (NO) situation that running switch 54 is opened, travel to S34, distinguish timer after the starting whether through 15 seconds.
In S34, be characterized as not through under 15 seconds the situation (NO), get back to the pre-treatment of S30.To become the time of closing be the short time to removing pressing force after opening to press running switch 54 the user.Like this, distinguish that in S34 running switch 54 through remaining after 15 seconds under the situation of unlatching, can be judged as: be not open by user's operation but on running switch 54 loading be unlocked or electric short circuit taken place.Thereby, in S34, distinguish through switch after 15 seconds to be still under the situation of unlatching (YES) S38 that divides a word with a hyphen at the end of a line, display abnormality on the LCD 57 of operation panel 17.In addition, also can not carry out abnormal show and get back to common halted state ground formation.
Even judging it is not to be made by user's operation under the situation of running switch 54 unlatchings, this situation can not be stored in the holder of controller 62 as wrong resume yet.This be because, exist the user to continue to push the possibility of the maloperation of running switch 54, prevent to be capped and to disappear by the wrong resume that maloperation should stay originally.
Be turned on between the igniting beginning from running switch 54, on the LCD 57 of operation panel 17, carry out the demonstration of " safety verification/timer ".By carrying out this demonstration,, can prevent to produce the suspicions whether dim wind warming machine 10 of combustion gas break down and feel to be nervous because the user can confirm whether the start of safety verification and timer is carried out.
As by the action of the flow chart among Fig. 5 of above explanation, by the running 54 pent moment of switch, with reference to the time diagram explanation igniting of Fig. 6 the zero hour how to change on one side.In Fig. 6, be closed in constantly different 3 incidents (incident 1, incident 2, incident 3) at the running switch, illustrate On/Off and the igniting and the fired state of the running switch 54 of each incident.In addition, in Fig. 6, time course is to pass through from left to right.
The running switch 54 that [incident 1] is unlocked becomes to cut out before safety verification is ended.Even running switch 54 becomes to cut out before safety verification is ended, do not begin igniting immediately yet, but after safety verification is ended, begin igniting.
In addition, the burning running begins like this: make electro-motor 36 work, led to electric ignitor 42 and produced electric sparks, electromagnetic switch valve 47,48 with electromagnetic proportional valve is opened, in combustion barrel 38 supply combustion gas and Air mixing gas, by lighting the gaseous mixture entry into service.
[incident 2] running switch 54, (from starting in 15 seconds of timer) becomes to close in the time of timer.If running switch 54 becomes to cut out in timer time, promptly begin to light a fire the running of burning from running switch 54 one-tenth moment of closing.
[incident 3] running switch 54 becomes to cut out through behind the timer time.At this moment, do not begin igniting, carry out abnormal show.Thus, do not implement the burning running.
Action about after the burning running beginning of the dim wind warming machine 10 of combustion gas is explained as follows.
In the burning running, controlled device 62 controls, electro-motor 36 rotates, and electromagnetic switch valve 47,48 is opened, and regulates the fuel gas supply amount by electromagnetic proportional valve 49.If electro-motor 36 rotates, be driven by it pressure fan 34 and also rotate, be taken into mouthful 14 indoor air from room air and be inhaled in the conduit 32 of blowing, flow through burner 39 around.Air one flows through around the burner 39, covers 31 owing to be provided with, and the pressure in the combustion barrel 38 becomes negative pressure, and room air is inhaled in the combustion barrel 38 via conduit 44.
If open electromagnetic switch valve 47,48, electromagnetic proportional valve 49 is regulated the fuel gas supply amounts, from the nozzle 46a of gas supply pipe 46 combustion gas is sprayed in the conduit 44, and mixes from the indoor air that is inhaled into.The air that mixes and combustion gas be in combustion barrel 38 internal combustion, as dim wind export from dim wind 15 blow out, warm indoor.Controller 62 is regulated the revolution of electro-motor 36 and the aperture of electromagnetic proportional valve 49 by from the input signal of room temperature configuration switch 55 with temperature sensor 51, therefore suitably controls heating installation air quantity and heater temperature.
In addition, controller 62, judges whether because anoxic or not igniting and can not burning under the situation below the assigned voltage in the output valve of thermocouple 42, close electromagnetic switch valve 47,48 and electromagnetism proportioning valve 49, implement fire extinguishing and control.
When the burning running, as 54 one-tenth unlatchings of running switch, close electromagnetic switch valve 47,48 and electromagnetic proportional valve 49 by controller 62 controls, stop the running of the dim wind warming machine 10 of combustion gas by the rotation that stops electro-motor 36.
