Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incinerator having a simple structure and capable of easily and efficiently incinerating wastes, which is particularly suitable for general household use.

[0002]

2. Description of the Related Art Today, while the amount of waste is increasing,
With the disposal capacity of public waste disposal facilities not being able to keep up with it and the capacity of public waste disposal sites approaching, a new disposal site cannot be secured and disposal of waste becomes a major social problem. Is well known. For this reason, it is necessary for each general household not to make garbage as much as possible, and it is also necessary to voluntarily dispose of the garbage, such as incinerating it with an incinerator. is there.

FIG. 4 shows the structure of a conventional incinerator which is generally used. In FIG. 4, reference numeral 41 is an incinerator, and a furnace main body 42 is formed in a tubular shape as a whole, and a chimney 43 is inserted through the upper surface thereof. Inside the furnace body 42, a net 44 for placing a fuel substance is arranged, and a combustion chamber 45 is defined above the net 44. Further, on the peripheral wall of the furnace body 42, a fuel material inlet 46 is provided above the position of the net 44.
Is formed and the lid 47 is attached to the lid 47 so that the lid 47 can be opened and closed.
At the lower end, which is below the position of the net 44, the combustion product discharge port 4
8 are formed.

The incinerator 41 has such a structure, a concrete board 49 is laid at the installation site, and the concrete board 49 is installed thereon.

Next, the operation of the incinerator will be described together with its usage. In FIG. 4, first, the lid 47 of the charging port 46 is opened, the fuel material is charged from there, and a certain amount of fuel material is placed on the net 44 in the furnace body 42. When the fuel is ignited by an ignition tool such as a match, air is supplied to the combustion chamber 45 through the outlet 48, and the fuel starts to burn. When the fuel substance has burned to some extent, the fuel substance is again charged from the charging port 46. The thermal power gradually increases to burn the fuel substance, and the smoke generated by this combustion is discharged from the chimney 43. After burning, the remaining combustibles such as ash are net 44
It falls from between and collects at the bottom. Outlet 48 as required
Take out the combustion products from.

As described above, in the above conventional incinerator, air is supplied into the furnace main body 42 through the combustion product discharge port 48 to burn the fuel product.

[0007]

However, in the above-mentioned conventional incinerator, since air is taken in from the discharge port of the combusted material, the air is simply supplied from the bottom to the top. However, this cannot increase the supply amount of air, and has the following problems. (1) The combustion speed is slow because the heating power cannot be increased. To incorporate the incineration of garbage in each household on a daily basis,
Increasing the burning rate is essential. (2) A large amount of smoke is emitted because complete combustion cannot be obtained.
A large amount of smoke emission is not suitable for use in residential areas. (3) A large amount of burnt residue such as ash remains because complete combustion cannot be obtained. If there is a lot of burnt residue, it will take some time to process it.

The present invention solves such a conventional problem, and has a simple structure for general households, which aims to strengthen the thermal power, increase the burning speed, improve the burning efficiency, and reduce the amount of smoke exhausted. An object of the present invention is to provide an incinerator that can reduce the amount of combustion products such as ash and is suitable for incinerating waste in each home.

[0009]

In order to achieve the above object, the present invention has a furnace body which is formed in a tubular shape and has a combustion chamber defined therein, and a chimney attached to the upper portion thereof. At the same time, the furnace body has a charging port for charging a fuel substance into the combustion chamber and an outlet port for discharging the combustion substance. Further, the furnace body releases a wide range of air into the combustion chamber. The gist is an incinerator having an air discharge pipe having a possible air discharge port and a plurality of air discharge holes, and a blower device for supplying air to the air discharge pipe.

[0010]

The present invention has the following functions due to the above-mentioned structure. First, a certain amount of fuel is introduced into the combustion chamber of the furnace body in advance from the introduction port. Next, by starting the blower,
Air is fed into the combustion chamber through the air discharge pipe. Here, the fuel article is ignited by an ignition tool such as a match. While the fuel substance gradually begins to burn, air is continuously actively discharged in multiple directions from a plurality of air discharge ports on the peripheral surface of the air discharge pipe by the supply of air by the blower. Due to such positive supply of air and discharge of air in multiple directions, the thermal power rapidly rises and the temperature of the combustion chamber is rapidly raised. As a result, the fuel substance is efficiently burned in a substantially complete combustion state in a short burning time, and the amount of smoke exhaust and the residual amount of the burned substance are greatly reduced.
