Abstract

PURPOSE:To perform heating by radiation heat and warm-air and deodorize malodor in a room by a method wherein platinum type metallic particles are supported on a column-shaped carrier which is made of heat-resistant material and has axial hollow-holes, heat-generating elements are inserted in through- holes, and a fan is mounted on an end of the carrier. CONSTITUTION:A column-shaped carrier 1 is made of honeycomb-like ceramic having a lot of open-end hollow-holes in a lattice-like pattern. Particles of platinum type metallic catalyst, such as platinum, palladium and others, are supported on the surface of the carrier 1 including the surfaces of the hollow- holes. The carrier 1 has two or more round through-holes 2 having a diameter larger than that of the hollow-holes, and heat-generating elements 3 that metallic wire is wound in a coil-shape are directly inserted in the through-holes. The carrier 1 is heated to a high temperature when the heat-generating elements 3 are energized, so that radiation heat from the surface can be used for heating. Air St is induced from an opening 5 into the carrier 1 by a fan 4. Malodor components are oxidized and destructed by the activated catalyst and turned into carbonic acid gas and water, and the air St is tuned into deodorized air S0.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a heating device using a t% heating element used for heating and drying.

Conventional technology A conventional heating device uses a heater or the like in which a coiled metal wire is built into a tubular ceramic body as a heat source.
Some have a fan placed at the axial end of the heat source. An example of a heating device using this fan will be described with reference to FIGS. 3 and 4.

FIG. 3 is a perspective view of a conventional heating device, and FIG. 4 is a side sectional view thereof. In the figure, 8 is a heater in which a heating element made of a coiled metal wire such as nichrome wire or Kanthal wire is arranged in a quartz tube. A reflecting plate 9 made of a metal plate or the like is provided behind the heater 8 so as to cover it. Below the heater 8, a fan 1o and a lower opening 11 are provided for sucking air by the fan 10, and above the heater 8, an upper opening is provided for discharging the air sucked by the fan 10. A vent 12 is provided.

In such a heating device, radiant heat obtained directly from the heater 8 and air sucked into the heating device by the fan 10 are heated behind the reflector plate 9, and the heated air is exhausted from the lower air opening. It was heated by the wind.

Problems to be Solved by the Invention However, the conventional heating device described above cannot purify indoor air when it is contaminated with bad smells from cigarettes, beds, etc. The odor was diffused into the room and at the same time the heater was used to heat it, making the odor worse.

Therefore, if the air in the room is dirty, it is no longer necessary to install a deodorizing device or the like separately from the heating device.

Means for Solving the Problem In order to solve this problem, the heating device of the present invention has the following configuration. A support made of a heat-resistant material having a large number of parallel hollow holes with openings on both sides is configured to extend parallel to the hollow holes, and platinum-based metal particles are supported on the support. There is. A heating element is disposed in a through hole provided in the support, and a fan is disposed at an end of the support.

Function: In the heating device having such a configuration, radiant heat is obtained from the support heated by one heating element, and the following functions are also provided. Since both ends of the support are open, cool indoor air is sucked into the heating device by a fan provided at the ends. And this sucked air is
The heated support body warms the air, which is then turned into hot air by the fan and discharged outside the apparatus. By the way, the catalyst layer of platinum-based metal particles supported on the support is heated to a high temperature and activated. Therefore, when the air sucked by the above-mentioned fan is dirty, the malodorous components can be decomposed into carbon dioxide gas and water by oxidation and deodorized. In other words, indoor air contaminated with cigarette and bed odors can be purified by this heating device.

As described above, this heating device not only provides a heating effect through radiant heat, hot air, and its circulation, but also deodorizes malodor components using the activated catalyst layer.
This makes it possible to collect heat in a clean indoor space.

EXAMPLE An example of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway side view of a heating device according to an embodiment of the invention, and FIG. 2 is a partially cutaway plan view of the heating device.

In the figure, reference numeral 1 denotes a support made of a heat-resistant material, Wayuru honeycomb-shaped ceramic, which has a large number of hollow holes 7 parallel to each other in a lattice shape with openings on both sides. It is formed. A particulate platinum metal catalyst such as platinum or palladium is supported on the surface of the support 1 including the hollow holes 7 . There are two methods for supporting the resin: a coating method and a dipping method, but the dipping method is preferable for uniformly depositing the resin on the side walls of the hollow holes of the honeycomb-shaped ceramic support 1. This support 1 has hollow holes 7
A plurality of cylindrical through holes 2 having a size υ larger than the hollow hole are provided in parallel with the hollow hole, and a heating element 3 made of a metal wire such as nichrome wire or Kanthal wire wound into a coil is directly arranged inside the through hole 2. ing. Also.

An upper opening 6 and a lower opening 6 are provided at the upper and lower ends of the support 1 for intake and exhaust air by a fan 4 provided below the support.

The operation of the heating device configured as above will be explained. First, by energizing the heating element 3, the support 1 is heated and reaches a high temperature, so that the support 1 can be heated by radiant heat obtained from its side surfaces. Second, when the support 1 is heated to 16° or higher, the catalyst of platinum-based metal particles supported thereon is activated and increases the oxygen concentration in the air layer within the hollow pores 7. By the way, in this honeycomb-shaped ceramic support 1, a large number of columnar hollow holes 7 are formed in a lattice pattern, and both ends of the hollow holes 7 are open, so that a large number of hollow holes 7 are formed in the vertical direction with penetrating shafts. be. Therefore,
The air flow S2 contains malodorous components such as cigarettes and bed,
The air is sucked into the support 1 through the upper opening 6 by the fan 4 . The malodorous components of this sucked air flow S2 are oxidized and decomposed by the activated catalyst described above and changed into carbon dioxide gas and water, resulting in a deodorized air flow S1. Further, this air flow S1 is deodorized and at the same time is warmed by the heated support and reaches a high temperature. This deodorized and warmed air flow S1 is discharged to the outside from the lower air opening 6 by the fan 4 as a deodorized warm air flow So.

As described above, in this heating device, heating by radiant heat can be obtained, and at the same time, indoor air can be sucked into the support and discharged as warm air to circulate the warm air. Furthermore, when the indoor air passes through the support, malodorous components can be deodorized and the indoor air can be purified.

Note that the heating element 3 disposed in the through hole 2 provided in the support 1 does not have an outer shell like the conventional heater 8.
Since the through hole 2 is placed directly inside the outer shell,
Since the support 1 can be heated to a higher temperature, the heating effect due to its radiant heat and warm air can be enhanced, and the catalyst can be further activated, so the deodorizing effect can be further enhanced. .

The number of through holes 2 provided in the support 1 may be at least one, as long as sufficient radiant heat can be obtained from the surface of the support and the temperature can be reached to activate the catalyst.

Further, as for the position where the through hole 2 is provided, it is preferable to provide the through hole 2 close to the side surface of the support 1 as in this embodiment in order to increase the radiant heat effect of the support 1. Furthermore, although the fan 4 provided for deodorizing and circulating hot air was provided below the support 1 in the fifth embodiment, it may be provided above the support 5 to reverse the flow of air. .

One reason for this is that the direction of air flow is determined depending on whether the main component of the odor is heavy or light relative to the air.

Furthermore, in this example, the shape of the support and the shape of the through hole formed inside the support are cylindrical, but if it can be configured so that the above-mentioned heating effect and deodorizing effect can be realized, what could be done? It may be configured by changing it to .

Effects of the Invention As described above, in this invention, a platinum metal catalyst is supported on the surface of a support made of a heat-resistant material having a large number of mutually parallel hollow holes that are open at both ends.

The following effects can be obtained by arranging the heating element in the through hole formed in the support and also arranging the fan at the end of the support.

First of all, radiant heating is obtained from the heated surface of the support. Second, the air flow that passes through the heated support and is discharged is obtained as hot air and has a heating effect, and the catalyst activated by the heating of the support removes all the malodorous components. Deodorizes dirty indoor air.

Therefore, it is possible to obtain a heating effect using radiant heat and hot air, and also to deodorize a room contaminated with cigarette and pet odors, thereby realizing heating in a clean indoor space.
