Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to a heating device such as a fan heater that uses gas, oil, etc. as a heat source. Effectively removes the odor caused by the oxidation of the solidifying agent contained in the product), the odor of cigarettes when living in a closed room, the odor of fish and garlic when used in Kirakin, the odor of garbage, and the unpleasant odor emitted by beds. This invention relates to a heating device with an air purifying function.

Conventional configuration and its problems Conventional fan heaters, for example, have the function of uniform temperature distribution indoors using a convection fan, and indoor humidification using the moisture contained in white clay and combustion exhaust gas with a rapid distribution. When reconsidered from the perspective of an air conditioner, it was a problem in terms of indoor air quality compared to FF warm air heaters, air conditioners, etc. That is, combustion exhaust gas was released into the room, polluting the indoor air. In addition, fan heaters are often used in living rooms and LDKs where there are people, but in spaces where people live, there is no need to worry about the smell of cigarettes, the smell of fish or garlic from cooking in the kitchen, the stench of garbage, or the smell of garbage. It did not have any self-cleaning effect against pet dust, odors, or the growth of bacteria and germs. Therefore, if the above-mentioned foul odor etc. fills the room, users are urged to ventilate the room by opening the window for at least one minute once every 30 minutes or turning on a ventilation fan. For example, in an 8-tatami room, the outside air is QC and the indoor air is 26C.

Normal ventilation frequency: 1 time/Hr・Window size: 1.8M
For a 1.8 m window, the emitted energy per minute corresponds to approximately 2eoK, c/h. Now, if we ventilate for 1 minute every 30 minutes, 2 minutes of ventilation per hour will release 620 f/h of energy, which is contradictory to recent energy savings. It is a hot air heater. Of course, one reason to be careful about ventilation is that if you use a fan fan heater for a long time as indoor rooms are becoming more airtight these days, the oxygen concentration in the room will drop. However, recent improvements in fan heater combustion technology or sensor technology as an incomplete combustion prevention device have reduced the indoor oxygen concentration to around 16% for combustion in fan heaters equipped with a general incomplete combustion prevention device. The combustor is a safety margin type combustor that does not generate CO/CO2 even when the temperature drops. On the other hand, since the incomplete combustion prevention device as a sensor operates at around 02 = 18%, from the viewpoint of safety as a combustion equipment, the incomplete combustion prevention device operates even without ventilation. However, since it is designed to be safe, there is no need to worry about conventional fan heaters or open stoves that do not have incomplete combustion prevention.

On the other hand, there are air purifiers that use activated carbon and dielectric filters to purify indoor rooms, but since these air purifiers do not have the ability to complete adsorption and desorption in the adsorbent part, for example, When the area around the adsorbent becomes saturated with water vapor, its function as an adsorbent deteriorates, and its function as an air purifier deteriorates, and its life usually ends in 6 months.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, and focuses on the fact that the adsorbent that removes bad odors, etc. physically adsorbs when the temperature drops and desorbs when the temperature rises. The purpose is to extend the life of the adsorbent by installing an activated carbon/electrostatic precipitator in the area where it physically adsorbs and desorbs when the temperature exceeds a certain level during use.

Structure of the Invention In order to achieve the above object, the heating device of the present invention includes a burner provided in the main body, a heat exchange section that mixes combustion gas with indoor air, and a fan motor that blows out warm air. , comprising an electrostatic precipitator filter and an adsorbent, the electrostatic precipitator filter and adsorbent are kept at room temperature before operation, and during use,
It is installed in a location where the temperature rises due to convection, radiation, or heat conduction, such as the indoor air intake port at the rear of the main unit, and by extending the life of the adsorbent as an air purifier through the adsorption/desorption cycle, This has the effect of purifying indoor air and saving energy by not requiring ventilation.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

A fan heater according to the present invention is shown in FIGS. 1 to 4, and FIG. 1 shows the external front part of the fan heater, with reference numeral 1 indicating a hot air outlet. FIG. 2 shows the external appearance of the rear part of the fan heater, and 2 indicates a filter section 3 which is an indoor air intake port.

Figure 3 is a sectional view of the unheater, and 4 is a burner;
5 is a thermal station that mixes combustion exhaust gas and indoor air; 6 is a fan motor that sucks the mixed hot air; and 7 is a flame rond that detects combustion.

Figure 4 shows details of the filter section, 2a is mesh #1
This is a 6.φ48 degree dust filter. 2b is an electrostatic dust collecting filter, 2c is an adsorbent, and the surface is covered with a nonwoven fabric.

Activated carbon 2C is installed at a location where the temperature is at room temperature before operation, and the temperature rises after a certain period of time after operation. The means for increasing the temperature may be any one of convection, radiation, and heat conduction. Activated carbon, zeolite, fine porous ceramics, etc. can be used as the adsorbent in this embodiment.

The operation of the above configuration will be explained below.

In FIGS. 3 and 4, the activated carbon 2C is at room temperature before the start of operation, but once the operation is started, the burner 4 burns and the combustion exhaust gas and indoor air are mixed in the heat exchanger 6. The mixed hot air is sucked by the fan motor 6 and blown into the room from the hot air outlet 1. In Fig. 5, after the start of operation, the adsorbent filter is close to room temperature, so the physical adsorption effect works, and as the room temperature rises, the adsorbent 2C is attached to the position where the temperature rises, so it adsorbs. Due to the desorption phenomenon of the agent, the water vapor surrounding the adsorbent disappears. Even if desorption occurs, it is completely removed by the flame. Thereafter, when a room thermometer (not shown) for detecting room temperature attached to the main body is activated, the fan heater shifts from strong twist firing to weak combustion, for example. In other words, if the electrostatic precipitator filter and adsorbent are installed at a temperature where the desorption is slightly lower than 1 in the case of strong twist firing, or the adsorption occurs at the time of stoppage, the life of the adsorbent will be increased and it will continue to absorb bad odors etc. be able to. Due to the fan motor 6, the foul odor and dust in the room always pass through the filter, and the foul odor and dust are actively sucked out.

In this way, according to this example, the adsorbent repeats adsorption and desorption, increasing the lifespan of the adsorbent. can be removed effectively and with a long service life. Furthermore, since there is no need to discharge bad odors through ventilation, there is no need to release wasteful energy to the outside, resulting in energy savings. Furthermore, second-hand smoke from cigarettes contains about three times as much nicotine and tar as mainstream smoke, which is a contributing factor to cancer, but since this second-hand smoke is also purified, it is also useful for promoting health.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

(1) Since the adsorbent repeatedly adsorbs and desorbs, it is possible to effectively remove odorants in raw gas and bad odors such as exhaust gas odors over a long period of time.

(2) Furthermore, since there is no need to discharge bad odors through ventilation, there is no need to release wasteful energy to the outside, resulting in energy savings.

(3) If the resident smokes, second-hand smoke contains about three times more nicotine and tar than mainstream smoke, which is a remote cause of cancer, but this second-hand smoke is also purified. So,
It improves health.
