Hereinafter, the best embodiment of an incense burner according to the present invention will be described with reference to FIGS. (Corresponding to claims 1 to 4)
FIG. 1 is an external view of an incense burner according to the present embodiment of the present invention.
In FIG. 1, an incense burner 1 has a tray 2 on which a liquid or solid material containing an aroma component can be placed, and a plate 2 placed on the lower side of the tray 2 and a candle 7 as a heat source inside. It has a heating furnace 3 for housing. The heating furnace 3 includes an intake hole 4, an exhaust hole 5, and a thin portion 6. In the incense furnace 1, when a material containing an aroma component such as incense is placed on the dish 2 and the dish 2 is heated by the lit candle 7, the aroma component is volatilized from the incense and dispersed in the air. At this time, the intake hole 4 takes air outside the heating furnace 3 into the heating furnace 3 and assists the burning of the candle 7. The exhaust hole 5 is a vent hole for discharging the air purified by a platinum catalyst installed on the bottom surface of the dish 2 described later to the outside of the heating furnace 3.
Further, the heating furnace 3 is formed with a thin part 6, and the thin part 6 has translucency, so that the light of the candle 7 burning inside the heating furnace 3 is leaked to the outside of the heating furnace 3. The incense burner 1 can also be used as a decorative lighting fixture. In the present embodiment, the thin-walled portion 6 is formed in a band shape in the peripheral portion of the heating furnace 3, but the shape is not particularly limited, and any shape can be used as long as it has translucency. It may be a shape.
In addition to the incense, tea leaves, coffee beans, aroma oil, and the like can be used as the material containing the aroma component placed on the plate 2.
And since the incense burner 1 is heated with the candle 7, especially the plate | pan 2 needs heat resistance. Accordingly, the material used is preferably a heat-resistant porcelain earth or a earth for earthenware prepared with a heat-resistant material. As the heat source, candles 7 are desirable, but even if a heat source such as an alcohol lamp or a gas lamp is used, the amount of heat generated and the distance between these and the plate 2 can be adjusted to adjust the aroma placed on the plate 2. This is not a problem as long as the material containing the components can be heated appropriately.

Next, Fig.2 (a) is a side view of the tray of the incense burner which concerns on this Embodiment, (b) is a perspective view of the heating furnace of an incense burner similarly. 2, the same parts as those shown in FIG. 1 are denoted by the same reference numerals, and the description of the configuration is omitted.
In FIG. 2A, a protrusion 8 is formed on the bottom surface of the plate 2, and a spiral spring 9 is formed in a concave portion (not shown in the figure) on the side of the protrusion 8. It is installed around. Although not shown in the drawing (shown in FIG. 3B), the spring 9 contains a plurality of spherical platinum catalysts, and the spring 9 functions as a catalyst containing portion for containing the platinum catalyst. Yes.
Further, in FIG. 2 (b), three exhaust holes 5 that are evenly arranged in the circumferential direction are provided in the upper portion of the heating furnace 3, and these exhaust holes 5 are connected to the inside of the heating furnace 3. The air purified by the platinum catalyst heated by the heating of the candle in the furnace can be evenly discharged to the outside of the censer 1. In the present embodiment, the exhaust hole 5 is formed to be a substantially semicircular hole when the dish 2 is placed on the heating furnace 3, but the shape is particularly limited. In addition, the number of installation is not limited to three, and may be two or three or more.
And since these exhaust holes 5 leak out the light of the candle which burns inside the heating furnace 3, the incense burner 1 is made to function as decorative illumination like the above-mentioned thin part 6. FIG.

Next, FIG. 3A is a side view of the censer plate according to the present embodiment, and FIG. 3B is a conceptual view of the censer spring.
3A, the plate 2 is in a state in which the spring 9 in FIG. 2A is removed, and a projection 8 is formed on the bottom surface of the plate 2 via a recess 10 at the bottom. The spring 10 shown in FIG. 2B can be supported by the recess 10. Although not shown, when the plate 2 is viewed from the bottom, the protrusion 8 is formed in a circular shape. When heated by a candle, the heat generated by the heating is transmitted to the protrusion 8, but the protrusion 8 is formed in a circular shape, so that the heat is conducted concentrically, and as a result, is carried by the recess 10 of the protrusion 8. Heat can be evenly transferred to the platinum catalyst contained in the spring. From such a viewpoint of heat transfer, the protrusion 8 is preferably circular, but is not necessarily circular, and may be polygonal. Further, the presence of the protrusion 8 locks the spring 9 carried by the recess 10 and makes it difficult to come off from the recess 10.
In FIG. 3B, a plurality of spherical platinum catalysts 11 are accommodated in the spring 9. When the spring 9 is attached to the projection 8 and the recess 10 of the plate 2 in FIG. 3A, the spring 9 is telescopic, so when pulled by hand, it is extended to the periphery of the projection 8 and released. Since the spring 9 contracts, it can be easily carried in the recess 10. In this embodiment, the spring 9 is shown as a catalyst container for the platinum catalyst 11, but the spring characteristic is not particularly required, and the platinum catalyst 11 can be accommodated and provided with a stopper. For example, it may be a net-like shape or a circular tube with a partial gap.
Further, since the spring 9 is made of stainless steel and is made of metal, it has good heat conduction, excellent heat transfer from the protrusion 8 and the recess 10 to the spring 9, and heat is easily transferred from the spring 9 to the platinum catalyst 11. Furthermore, stainless steel has heat resistance and has the advantage of being resistant to rusting.
The platinum catalyst housed in the spring 9 is formed into a plurality of spheres, but it is not particularly required to have a sphere shape, and a plurality of cubes and the like that can take a larger surface area than a single body. A cone or a column may be used.

Subsequently, the air cleaning function of the incense burner according to the present embodiment will be described with reference to FIG.
FIG. 4 is a conceptual diagram showing the usage status of the incense burner according to the present embodiment.
In FIG. 4, in the incense furnace 1, the candle 7 installed in the heating furnace 3 is ignited, and a flame 13 is lit at the tip of the core 12 of the candle 7. By this flame 13, the air taken in from the intake holes 4 rises while forming a convection heat layer inside the heating furnace 3, and heats the protrusions 8 formed on the bottom surface of the dish 2. In the present embodiment, 100% palm oil is used as the candle 7.
Although shown separately in the figure, in reality, the protrusion 8 on the bottom surface of the pan 2 placed on the heating furnace 3 is heated by the flame 13 of the candle 7, and the heat is conducted concentrically from the center. It is transmitted to the spring 9 carried in the recess of the protrusion 8. As described above, since the spring 9 made of metal stainless steel has good heat conduction, the heat of the spring 9 is quickly and uniformly transmitted to the platinum catalyst 11 housed in the spring 9. The platinum catalyst 11 is activated by heat, generates a clean gas 14 that decomposes and cleans pollutants and harmful substances such as volatile organic compounds present in the air, and exhausts from the exhaust hole 5 of the heating furnace 3. It can be discharged outside the incense burner 1. Further, since the light of the flame 13 of the candle 7 passes through the thin portion 6 and leaks to the outside, and the light of the flame 13 also leaks from the exhaust hole 5, the incense burner 1 can also be used as a decorative lighting fixture. it can.
In the figure, the dish 2 is aired without placing incense or the like, but in the case of airing, only air purification by the platinum catalyst 11 is performed. When an incense is placed on the plate 2, it is efficient because air purification of the platinum catalyst 11 and release of the aroma component by incense can be performed simultaneously.

Next, a temperature change in the vicinity of the platinum catalyst when the incense burner according to the present embodiment is used will be described with reference to FIG.
FIG. 5 is a graph of measurement results showing the temperature in the vicinity of the platinum catalyst of the incense burner according to the present embodiment over time.
In the measurement, the temperature was measured using a digital thermometer (Digital Controller SR90 manufactured by Shimaden Co., Ltd.), and a super-wire sheath thermocouple (K0.2 mmφ) was used as the thermocouple. Moreover, the temperature change with time was recorded using a voltage logger.
A sheath thermocouple was installed in the vicinity of the platinum catalyst, and then the candle was ignited. After ignition, the temperature in the vicinity of the platinum catalyst was measured every minute until the candle disappeared.
In FIG. 5, the temperature in the vicinity of the platinum catalyst rapidly increases after ignition, and then increases slightly with time, but shows a temperature between 200 ° C. and 230 ° C. from about 30 minutes until the candle disappears. Yes.
In general, the platinum catalyst can completely oxidize and decompose pollutants and harmful substances such as volatile organic compounds such as hydrocarbons and carbon monoxide. Substances that can be decomposed vary depending on the temperature. At temperatures up to about 230 ° C, carbon monoxide, methyl alcohol, formaldehyde, acrolein, benzene, toluene, m-xylene, methyl ethyl ketone, ammonia, trimethylamine, etc. are oxidized and decomposed. After the treatment, it is detected at 1 ppm or less in the measurement such as gas chromatography and does not show odor.
In the present embodiment, as shown in FIG. 5, since the platinum catalyst is heated to about 230 ° C., it is considered that the above-mentioned contaminants can be oxidized and decomposed.

Then, the result of having investigated the density | concentration change of ammonia and formaldehyde among the above-mentioned harmful gas using the platinum catalyst of the incense burner which concerns on this Embodiment is demonstrated using FIG.6 and FIG.7.
First, FIG. 6 is a graph showing the change over time in the ammonia concentration when the platinum catalyst of the incense burner according to the present embodiment is used.
The experiment was conducted by the following method. Ammonia was collected in a predetermined amount of gas bag (30 liters), introduced with dry air, and allowed to stand at 30 ° C. for 3 hours to vaporize the ammonia and adjust 10 ppm of ammonia gas. And after putting the heating apparatus which equipped the platinum catalyst in 10 liter gas bag, the gas bag was sealed. The gas bag was filled with 10 ppm of ammonia gas, and heating of the heating apparatus was started immediately. The time course of the ammonia gas concentration was measured using an ammonia gas detector tube. As a comparison, the change over time in the ammonia gas concentration was also measured under the same conditions in a heating apparatus without a platinum catalyst.
In FIG. 6, the ammonia concentration is all abruptly lowered at 5 minutes from the start of measurement, and is 2.5 ppm when there is a platinum catalyst and 3.5 ppm when there is no platinum catalyst. This is thought to be due to the ammonia concentration being drastically reduced by the ammonia gas being diluted with the air around the heating device or adsorbed on the surface of the heating device when the heating device is filled. And when there is no platinum catalyst with time, there is almost no change in ammonia concentration, whereas when there is a platinum catalyst, the ammonia concentration further decreases with time, and the ammonia gas is decomposed by the activity of the platinum catalyst. It is thought that it was done.

Next, FIG. 7 is a graph showing the change over time in the formaldehyde concentration when the platinum catalyst of the incense burner according to the present embodiment is used.
The experiment was conducted by the following method. Formaldehyde was collected in a predetermined amount of gas bag (30 liters), dried air was introduced, and the mixture was allowed to stand at 30 ° C. for 3 hours to evaporate formaldehyde to adjust 65 ppm of formaldehyde gas. And after putting the heating apparatus which equipped the platinum catalyst in 10 liter gas bag, the gas bag was sealed. The gas bag was filled with 65 ppm of formaldehyde gas, and heating of the heating apparatus was started immediately. The change over time of the formaldehyde gas concentration was measured using a gas detector tube for formaldehyde. For comparison, the change over time of the formaldehyde gas concentration was also measured under the same conditions in a heating apparatus not equipped with a platinum catalyst.
In FIG. 7, the formaldehyde concentration is drastically decreased in 5 minutes from the start of measurement, and is 12.5 ppm when the platinum catalyst is present, and 25 ppm when the platinum catalyst is absent. As in the case of ammonia gas shown in FIG. 6, the formaldehyde concentration is rapidly increased by diluting the formaldehyde gas with the air around the heating device or adsorbing it on the surface of the heating device when the heating device is filled. It is thought that it fell to. And when time passes further, when there is no platinum catalyst, the formaldehyde concentration is hardly changed, but when there is a platinum catalyst, the formaldehyde concentration greatly decreases with time, and after 30 minutes, almost 0 ppm. Is shown. This result shows that formaldehyde is reliably decomposed by the activity of the platinum catalyst.

  In this embodiment configured as described above, when a material containing a fragrance component is placed on a plate and heated by a heat source such as a candle, the fragrance component is volatilized from the material on the plate and is good for the use space. Can satisfy the fragrance. In addition, since the bottom of the plate is equipped with a platinum catalyst, the heat of the candle is used to activate the platinum catalyst and decompose harmful substances such as ammonia and formaldehyde in the air to produce a purified gas. The air can be cleaned. Further, since the candle light leaks to the outside due to the thin wall portion and the exhaust hole of the heating furnace, it can be used as a decorative lighting device.

  As described above, the invention described in claims 1 to 4 of the present invention can provide an incense burner to which an air purifying function is added, and can be used in general households.
