[0026]
Next, the operation of the embodiment of the present invention will be described.
If the operation switch 65 is pressed now, the vaporization heater 26 is energized to start preheating of the vaporizer 25, and the vaporization temperature sensor 27 detects that the vaporizer 25 has reached the vaporizable temperature of the fuel oil. Thus, drive signals are output from the control device 55 to the electromagnetic pump 20, the combustion fan 23, and the igniter 30, respectively, and combustion in the premixing system is started in the burner unit 9. Warm air is discharged from the hot air outlet 3 to heat the room.
[0027]
At the same time as the drive signal from the control device 55 to the electromagnetic pump 20, the drive signal is also output from the control device 55 to the negative ion generating device 32, and about 3,000 to 5,000 negative ions / CC from the discharge needle 33. The negative ions are combined in the vicinity of the hot air outlet 3 among the positive ions and the negative ions generated by the combustion in the burner unit 9, and the negative ions are more positive ions in the indoor ion balance. More than 3,000 to 7,000 / CC.
Furthermore, although the difference is also in the calorie calorie, the maximum calorie is of 2,750 kilocalorie / h, with about 4,000 ions / CC negative ions increased in high heat power, and about 6,000 cells / CC in low heat power. There are many negative ions.
[0028]
On the other hand, when the operation switch 65 is pressed again, the heating operation is stopped by stopping energization of the driving components such as the vaporization heater 26, the electromagnetic pump 20, the combustion fan 23, and the blower fan 5 by the control device 55. Combustion of the burner unit 9 is extinguished and hot air heating is also stopped, and the negative ion generating means 32 is also stopped by a drive stop signal from the control device 55 in synchronization with the drive stop of the electromagnetic pump 20. Thus, the generation of negative ions is stopped.
[0029]
Therefore, the number of positive ions and negative ions generated by combustion has been balanced in the same number as before, and the artificially generated ions themselves disappear in a few seconds. It was not, but by reducing positive ions generated during combustion by the negative ion generator 32 and making the ion balance in the room rich in negative ions, it is refreshing and refreshing to feel near the waterfall. The feeling is obtained, and it is good for recovering from fatigue so that the feeling of frustration can be eliminated.
[0030]
Furthermore, during the heating operation, the indoor air flows into the device body 1 from the ventilation surface 39 of the fan guard 7 by driving the blower fan 5, so that the indoor air circulates through the deodorizing filter 41 and the sterilizing filter 43. The deodorizing filter 41 on the upper side of 7 deodorizes the source of odors such as tobacco odor and pet odor in the air by adsorbing the acetaldehyde adsorbent and zeolite component in the deodorizing filter 41. 41 is provided on the upper side of the fan guard 7 for several tens of seconds once the blower fan 5 is used to reduce the odor at the time of fire extinguishing. The odor at the time of fire extinguishing is also reduced, and if the blower fan 5 is driven again for cooling after that, the deodorizing filter 41 also restarts the deodorization of the indoor air. Further, since the deodorizing filter 41 is composed of the light regeneration catalyst 46, the light regeneration catalyst 46 is taken out from the filter cover 47 and exposed to direct sunlight to dissolve and adsorb the odor component to which the titanium oxide component is adsorbed. The ability is regenerated so that it can be used semipermanently.
[0031]
During heating, room air also flows through the sterilization filter 43 provided on the lower side of the fan guard 7, so that mold and bacteria in the air collected by the filter paper 49 are strongly sterilized by the lytic action of natural enzymes. Thus, the indoor air can be brought into a good state free of bacteria, and the two filters 41 and 43 can simultaneously deodorize and sterilize the indoor air together with the indoor heating, thereby providing clean air. It is possible to obtain a comfortable space.
[0032]
Further, since the deodorizing filter 41 and the sterilizing filter 43 are provided with air circulation gaps 44 and 45 between the ventilation surface 39 of the fan guard 7 to which the deodorizing filter 41 and the sterilizing filter 43 are attached, Even if clogging is caused by dust, the room air for hot air flows in through the flow gaps 44 and 45, and the apparatus main body 1 itself burns out due to a decrease in the amount of hot air or a temperature increase in the apparatus main body 1. Even if the filters 41 and 43 are not frequently cleaned without causing an abnormal situation, normal warm air heating is performed without any trouble and can always be used with peace of mind.
Of course, if the filters 41 and 43 are regularly cleaned, the indoor air can be deodorized and sterilized simultaneously with heating as described above.
[0033]
Also, here, negative ions are radiated in the air, so that negative ions adhere to odor components and bacteria in the air, and the amount of attachment to the deodorizing filter 41 and the sterilizing filter 43 is doubled. Bacteria ability is improved, and the room air can be cleaned in a short time.
[0034]
In addition, although this one Embodiment demonstrated what provided the two filters of the deodorizing filter 41 and the microbe elimination filter 43, it is not limited to this, For example, either one filter may be sufficient.
[0035]
【The invention's effect】
As described above, according to the present invention, indoor deodorization and / or sterilization can be performed while warm air heating is performed, which is very convenient. Since air circulation gaps are formed between the airflow surfaces of the air vents, even if the filter is clogged with dust or dust, the air is supplied through the circulation gaps, reducing the circulation volume. There is no need to stop or stop, and the hot air is used as usual, so there is no risk of burning the instrument body and burning the instrument body, and it is safe to use and there is no need for the user to clean the filter frequently. Is a good one.
[0036]
According to claim 3, since the deodorizing filter is composed of a photoregenerative catalyst, it is regenerated by periodically drying in the sun and direct sunlight, so it can be used semipermanently and is very convenient. It is also economical.
[0037]
According to the fourth aspect of the present invention, the sterilization filter is made of filter paper impregnated with an enzyme, so that bacteria in the air can be easily sterilized with a simple configuration, and this filter is also semi-permanent. It can be used and is economical.
[0038]
Further, according to claim 5, the total area of the deodorizing filter and the sterilizing filter is less than half of the area of the ventilation surface of the fan guard, so that the air flow for hot air can be reliably ensured. Since it has a distribution gap, warm air heating is performed more reliably and it can be used with peace of mind.
