Abstract
The invention aims to provide a heater fan which can reduce the smelly odor that the user smells when the heater fan is ignited. The heater fan comprises a control combustion pump 7, a heater 8 used for gasification, a convection fan 2, an igniter 10 and a control part used for controlling the combustion of a combustor 1. When the heater fan is ignited, the convection fan is stopped. The delay time is changed when the heater fan is ignited until the convection fan 2 is driven according to the temperature of a gasifier 6 at the time the gasifier 6 starts to run.
Description
The invention relates to a kind of liquid fuel of combustion gasification and give off the warm-air drier of hot blast.
This combustion gasification liquid fuel in past and give off the warm-air drier of hot blast can produce some imperfect combustion odorous gas such as portion gas in igniting.Fig. 7 be in the past warm-air drier want portion's cutaway view.
In Fig. 7, the 1st, make the burner of the liquid fuel combustion that has gasified, the 2nd, the convection fan of the hot blast that discharging is generated by burner 1, the 3rd, form the combustion barrel of the flame span on the top of burner 1, the 4th, hot-blast outlet, the 5th, air inlet.
Begin to illustrate its course of work below.
Promptly on burner 1, form flame after fuel takes fire, in combustion barrel 3, begin to rise to the outside of combustion barrel 3 by the high-temperature gas of this flame heat generation.This high-temperature gas is pushed to the front with by convection fan 2 from air inlet 5 inhaled airs together, is discharged by hot-blast outlet 4, is used to heating of house.But because the imperfect combustion gas that produces when the igniting action partly waits odorous gas also to emit from hot-blast outlet 4 in the mode that above-mentioned high-temperature gas is pushed out, institute is so that stink can directly blow to the user.
One of method of the foul smell that produces when avoiding lighting a fire stops operating the regular hour convection fan 2 when the igniting action exactly.
Fig. 8 is exactly the partial sectional view that adopts a kind of warm-air drier of this method.After the burning beginning, the High Temperature Gas cognition that the flame heat that burned device 1 forms generates rises to outside the combustion barrel 3.Because convection fan at this moment 2 is staticly not change, there is not enforceable air stream.At this moment, high-temperature gas will export 4 high air inlets 5 from the present position than hot blast in the mode of free convection and discharge diffusion.Then, after the time delay by settings such as timers in advance, convection fan 2 promptly starts rotation, and hot blast just emits from hot-blast outlet 4 with the airflow direction among Fig. 7, is used for heating of house.
In other words, the foul smell that produces when igniting is discharged into the back side diffusion of the warm-air drier that is provided with air inlet 5 together with high-temperature gas, so just eliminated the phenomenon that directly blows out foul smell to the user of front.
Also have a kind of method, its utilizes is not the fixing time delay that device such as timer be scheduled to, begins to the time delay of startup convection fan 2 but utilize a detectable signal that point catches fire to decide from the igniting action.General, whether surveying has caught fire is confirmed by means of flame forms delay.So, detecting method that the back that catches fire starts convection fan 2 and not only having with aforesaid, causing flame to form the effect that also can receive the minimizing foul smell in late really effectively owing to reasons such as gasification hysteresis with the same effect of the method for devices such as timer.
Fig. 9 has represented the key diagram of the concentration of foul smell along with the relation of variation time delay of convection fan 2.When convection fan 2 began to rotate before the igniting action, foul smell was because of diluted, and its concentration descends to some extent.
On the other hand, when and then starting convection fan 2 after the igniting action, the concentration of foul smell is the highest.This is to be pulled to the front because of these foul smell quickly.The concentration of foul smell is along with the time delay of convection fan 2 is elongated more and more lower after this, and the foul smell that user in front feels also can be fewer and feweri.
Figure 10 is the schematic diagram of the temperature of expression warm-air drier back side hot gas along with the length rising time delay degree variation of convection fan 2.The hot air temperature at the warm-air drier back side is along with the prolongation of the time delay of convection fan 2 and is tending towards rising.
The hot air temperature at the warm-air drier back side also is subjected to the influence of the changes in temperature degree of warm-air drier body interior.Main body is when starting (thermal starting, HOT START) under the situation of preheating, and when starting under for example just used situation, the velocity ratio that the temperature of back side hot gas rises wants fast when starting (cold start-up, COLD START) under the situation of main body cooling.
Because warm-air drier in the past is an as above structure, during convection fan 2 stops operating, but to before reaching more than the setting, the hot air temperature of discharging from the warm-air drier main body back side to start convection fan 2, set the setting that a fixed value satisfies the hot air temperature at the back side for the time delay of convection fan 2, must effectively utilize the concentration that regularly reduces foul smell.
The catch fire method of detectable signal of utilization then is subjected to the influence of detection circuit easily, because the fault of detection circuit or surveys hysteresis because point is flourishing, the startup of the convection fan 2 also hysteresis of delaying time will have the problem of the temperature setting that can't satisfy back side hot gas.
For addressing the above problem, the purpose of this invention is to provide the warm-air drier that the time can reduce the foul smell that the user feels in igniting.
Warm-air drier among the present invention is such formation, when igniting, and convection fan 2 stalls, the temperature of the gasifier when beginning according to running simultaneously changes from igniting and begins to the time delay of convection fan 2 startups.
Also have, the warm-air drier among the present invention has been set up thermal insulation board on the top of air inlet 5 on the basis of said structure.
Warm-air drier among the present invention is also set up activated carbon with deodorization functions etc. on thermal insulation board on the basis of said structure.

Fig. 1 is the structure chart of expression first kind of embodiment of the present invention.The same symbol has all been put at position the same with past warm-air drier among Fig. 7 among the figure, here just no longer describes.
In Fig. 1, the 6th, the gasifier of the liquid fuel that has gasified is provided to burner 1, the 7th, the petrolift of liquid fuel is provided to gasifier 6, the 8th, place the gasification heater of gasifier 6, the 9th, the temperature sensor of detection gasifier 6 temperature, the 10th, light the igniter of flame in when igniting to burner 1, the 11st, control convection fan 2, petrolift 7, gasification are controlled at the control section that burner 1 burns with heater 8 and igniter 10.
Fig. 2 is a flow chart of having represented the course of work of the above embodiments 1.The user presses running button (not shown) and makes the warm-air drier entry into service, at first measures the temperature (the 20th step) of gasifier 6 with temperature sensor 9.The changes in temperature degree of body interior when this measured value is used to infer the running beginning.By this temperature,, just can derive the time delay (the 22nd goes on foot) of convection fan 2 with reference to the tables of data (the 21st step) that is stored in advance in the ROM in the control part 11 etc.
According to these data, under the prerequisite of the setting that satisfies warm-air drier back side hot air temperature, start convection fan 2 with the time-delay that can reduce odor concentration.When promptly the temperature of the gasifier of measuring in the 20th step is high (more than 90 ℃), lack the time delay of convection fan 2 (2 seconds), on the contrary, when aforesaid temperature is low (less than 90 ℃), then can prolong time delay (4 seconds), make odor concentration reduce greatly.
Then, begin to control gasifier, make the temperature of gasifier 6 remain on (200～300 ℃) in the incendivity temperature range (the 23rd step) with heater 8.Because at this moment also do not light a fire action, be masked as for 0 (the 24th step) so whether light a fire.Then, the temperature of gasifier 6 reaches set point of temperature (200 ℃), just can light a fire (the 25th step).Igniter 10 is started working after (the 26th step), with petrolift 7 beginning feed fluid fuel (the 27th step).Liquid fuel by gasification back supplied burner 1, is lighted the back and is formed flame in gasifier 6.After igniting action lasting till that always igniting is detected, after igniting was identified (the 28th step), whether light a fire indicated and was put for 1 (the 29th step), igniter 10 quit work (the 30th goes on foot).
On the one hand, convection fan 2 was kept before the time delay that process drew in preceding the 22nd step and is stopped (the 31st step), and stink compositions such as the imperfect combustion gas that produces during igniting are discharged into the back side diffusion of warm-air drier main body along with the high temperature gas flow shown in Fig. 1.Then, passed through that convection fan 2 begins rotation (the 32nd step) after time delay, high-temperature gas is used for heating of house along with the air-flow of the hot blast shown in Fig. 7 emits from hot-blast outlet 4.
