Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hot air heater having an air cleaning function,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot air fan, and more particularly to a hot air fan equipped with an air purifying function.

Recently, as regulations for environmental pollution are strengthened, electric hot air fans are widely used, and air purifiers are also increasingly used.

Air purifiers are known in various ways such as filter type, electrostatic precipitator type, complex type, anion purification type, and water filter type. However, most of the air purifiers known in the art are not well deodorized when they are well cleaned, And troublesome problems such as frequent cleaning or replacement of the filter.

On the other hand, Japanese Laid-Open Patent Publication No. 2001-97924 discloses a duct in which external air inlet, outlet, and clean air supply ports communicate with each other; A damper installed on the inlet side of the duct to selectively seal the inlet thereof; A filter installed on the inlet side of the duct for removing dust from the air; A catalyst member for decomposing harmful components in the incoming air primarily filtered by the filter into harmless components; And a control damper installed at a boundary between a discharge port of the duct and a clean air supply port to selectively block and open / close the passage.

The air purifier drives the fan to suck the noxious gas from the room into the duct for one day to one week to allow the noxious gas to pass through the catalyst member to adsorb the noxious gas to the catalyst of the catalyst member, After the inlet, outlet and clean air inlet are closed, the heater is driven to heat the system to decompose the harmful gas passing through the catalyst bed into harmless gas, then open the damper and control damper to remove the purified air Indoor or outdoor.

Such an air purification apparatus has an independent heater at the front end of the catalyst member, and indirect heating type in which the heater is operated and heated hot air is supplied to the catalyst member to activate the catalyst, so that the reaction speed is low and the catalytic reaction efficiency is low.

In addition, when the air purifier is operated, noxious gas in the room is sucked into the duct for 1 day to 1 week and adsorbed to the catalyst of the catalyst member, and the inlet and outlet of the duct and the clean air supply port There is a problem that the treatment time is very long because the system is heated by driving the heating heater after sealing the noxious gas passing through the catalyst layer by decomposing the noxious gas passing through the catalyst layer into the harmless gas.

In addition, since the heater and the catalytic reactor are separately formed, the conventional air purifying apparatus can not control the capacity of the heater.

The plurality of hollow cells 136 may be formed in one of various shapes such as a wave shape, a hemisphere shape, a triangle shape, and a square shape.

6, the catalyst carrier 137 increases the surface area at which the catalyst 43 is coated on the surface of the base material 41, and at the same time, increases the ceramic composition The base coat 42 is formed. On the surface of the base coat 42, an oxidation or reduction catalyst 43 is selected or coated in combination.

FIG. 8 is a cross-sectional view showing an exemplary structure of a heating and catalytic reaction module applied to the second embodiment of the present invention, and FIGS. 9A to 9C are views showing a combination of a heater and a catalyst carrier in the heating and catalytic reaction module of FIG. 10 is a view for explaining a method of assembling a heater and a catalyst carrier in the heating and catalytic reaction module of FIG. 8. FIG. 10 is a side view, a front view and a perspective view, and FIG.

The heating and catalytic reaction module applied to the second embodiment of the present invention comprises a housing 10, a heater 20, and a catalyst carrier 30.

The housing 10 is provided with a cylindrical space for accommodating the heater 20 and the catalyst carrier 30 therein. The housing 10 is provided with an inlet 11 through which the exhaust gas flows into one side and an outlet 11 through which the indoor exhaust gas from the odor of the exhaust gas flowing through the catalyst carrier 30 is exhausted. (12).

The inlet port 11 and the outlet port 12 are formed in the housing 10 so that the exhaust gas flowing into the inlet port 11 can be discharged after surely passing through the catalyst carrier 30 disposed inside the housing 10. [ The inlet port 11 is disposed on the lower side when the housing 10 is vertically arranged and the outlet port 12 is provided on the upper side of the catalyst carrier 30. [ .

The heater 20 includes a winding portion 20a wound in a coil shape having an inner space in the middle by using a sheath heater having a heating element embedded in the metal tube as a heating element, and the coil shape is preferably cylindrical .

However, the winding form of the winding portion 20a is not necessarily cylindrical, but may be formed in various shapes such as a triangular or square cross-section, or a truncated conical shape in which the internal space is gradually reduced toward the outlet. Or the like. Such a shape is not particularly limited, and it is natural that it can be deformed into any shape as long as a predetermined inner space can be formed in the heater 20. [

The shape of the winding portion 20a is preferably formed in a cylindrical shape in consideration of the fact that the inner catalyst carrier 31 and the outer catalyst carrier 32 that are coupled to the inside and the outside of the winding portion 20a are formed in a winding manner Do.

However, when the inner catalyst carrier 31 and the outer catalyst carrier 32 are made of a metal thin film, some degree of elastic deformation can be achieved even if they are wound in a cylindrical shape. Therefore, when the winding portion 20a is formed into a rectangular tube shape and the inner catalyst carrier 31 and the outer catalyst carrier 32 are formed in a shape corresponding thereto, the heater 20 and the supports 31, Can be maximized.

The sheath heater is formed by inserting filaments in the center of various sheaths, putting high-purity magnesium powder or aluminum oxide powder having high heat insulation and high heat conductivity therebetween, compressing the sheath outer diameter at a high pressure So that the temperature difference between the inner heating wire and the sheath is sufficiently lowered, and there is no fear that the heating and breaking of the heating wire due to oxidation or eccentricity of the heating wire will occur. Also, since the sheath heater has a structure in which the both ends of the filament are connected to the one and the other power terminals 15 and 16, the sheath heater has a low manufacturing cost and excellent durability life.

As the heat generating material of the heater 20, other kinds of heaters having the same function as those of the sheath heater may be used.

The power supply to the heater 20 is applied between the one and the other power supply terminals 15 and 16 extending in the axial direction from the winding portion 20a and is provided with a terminal, a flat terminal, or a lug terminal, Can be used.

Also, the heater 20 may be configured using a cartridge heater in the form of a single terminal in which a pair of power terminals 15, 16 connected to the heating wire are disposed at one side.

In the following description, the heater 20 having the cylindrical winding portion 20a will be described as an example.

The catalyst carrier (30) includes an inner catalyst carrier (31) and an outer catalyst carrier (32). That is, the inner catalyst carrier 31 is a cylindrical catalyst carrier disposed inside the cylindrical winding portion 20a in the heater 20, and the outer catalyst carrier 32 is located outside the heater 20 in the outer side of the winding portion 20a Which is a cylindrical catalyst carrier. The inner catalyst carrier 31 is formed to have an outer diameter equal to or smaller than the inner diameter of the winding portion 20a so as to be inserted into the winding portion 20a of the heater 20. [

Meanwhile, the outer catalyst carrier 32 is formed in a cylindrical shape so as to surround the heater 20 including the inner catalyst carrier 31 from the outside, and the heater 20 is preferably inserted into the outer catalyst carrier 32. For this purpose, the outer catalyst carrier 32 is formed so as to have an inner diameter which is equal to or slightly larger than the outer diameter of the winding portion 20a of the heater 20.

In addition, the inner catalyst carrier 31 is composed of a plurality of cells 30a in the form of honeycomb, and a fluid passage can be formed in the longitudinal direction of the cylinder. In addition, the outer catalyst carrier 32 preferably comprises a plurality of cells 30a in the form of a honeycomb formed with fluid movement passages in the longitudinal direction of the cylinder.

The catalyst supports 31 and 32 may be made of, for example, a material in which platinum, cobalt, nickel, palladium or nanosilver is coated as a catalytic metal on a thin plate of a FeCrAl heat resistant alloy having a thickness of 20 to 100 μm, ) Is welded to each contact portion where the corrugated wafers 30c are in contact with each other to form a cylindrical or cylindrical shape so that each cell 30a has a honeycomb structure.

The catalyst carrier (31, 32) is set to have a catalytic activation temperature of, for example, 200 to 600 ° C depending on the type of the catalyst metal. The cells 30a of the catalyst supports 31 and 32 may be hemispherical or triangular depending on the shape of the wave plate 30c. Here, the inner catalyst carrier 31 and the outer catalyst carrier 32 may have various forms as well as the honeycomb type described above.

As the FeCrAl-based alloying material, a ferroalloy alloy or Fe-20Cr-5Al-REM (rare earth metal) (including about 1% of REM (Y, Hf, Zr)) synthesized at a ratio of Fe-15Cr- .

In addition, the catalyst supports (31, 32) may have a square or circular shape with a plurality of hollow cells made of ceramics as another honeycomb structure.

According to the heating and catalytic reaction module of the second embodiment of the present invention, the heater 20 and the catalyst carrier 30 can be brought into direct contact with each other over a large area, 30) and the reaction efficiency of the catalyst are improved. As a result, conventionally, a high capacity heater of 350 to 450 W was used, but in the present invention, it becomes possible to use a low capacity heater of 150 W or less.

As a result, the exhaust gas is treated by heating the catalyst carrier 30 at an appropriate temperature with a minimum energy, so that the total energy of the exhaust gas discharged to the outlet 12 of the housing 10 also becomes low. Accordingly, it is possible to minimize the drive of the suction motor for introducing the outside air for lowering the temperature of the exhaust gas.

Further, since the winding portion 20a of the heater 20 is inserted and formed in the middle of the catalyst carrier 30, the size of the exhaust gas purifying carrier converter can be minimized. As a result, the conventional structure in which the winding portion of the heater is disposed outside the catalyst carrier 30 has a length of 190 mm, but in the present invention, it is possible to greatly reduce the length to 110 mm.

Next, a process of manufacturing the exhaust gas purifying catalyst converter as described above will be described with reference to FIG.

First, a heating element made up of a sheathed heater is wound in a cylindrical shape to fabricate a heater 20 having a winding portion 20a and linear power terminals 15 and 16 extending from both ends thereof.

Further, in the catalyst carrier 30, the inner catalyst carrier 31 may be formed by brazing a wave plate 30c corrugated on the flat plate 30b for each contact portion by using a material coated with a catalytic metal on a thin plate of a heat- The outer catalyst carrier 32 is formed by winding a wave plate 30c corrugated on the flat plate 30b by brazing (or diffusion bonding) the wave plate 30c for each contact portion, And each cell 30a has a honeycomb structure, for example.

That is, the inner catalyst carrier 31 is prepared by machining into a cylindrical shape having a diameter substantially equal to the inner diameter of the winding portion 20a of the heater 20, and the inner diameter of the inner catalyst carrier 31 is made equal to the outer diameter of the winding portion 20a of the heater 20 The outer catalyst support 32 is processed into a cylindrical shape having an inner diameter and at the same time having an outer diameter equal to the inner diameter of the housing 10 of the exhaust gas purifying use support converter to be inserted into the heater 20.
