[Industrial applications]

 The present invention relates to a refuse incinerator used at home.

[0002]

[Prior art]

 Household garbage incinerators are often made of iron plates, but they are prone to corrosion and have problems with durability.

[0003] Some castings are used in consideration of durability, but conventional castings are formed by stacking at least three or four ring-shaped parts, which increases the number of parts. It is disadvantageous in terms of manufacturing cost and handling. In addition, the inner wall of the stacked furnaces impairs the smooth flow of combustion gas, resulting in lower combustion efficiency. It should be noted that the black-brown color of the casting skin is left as it is, which is unaesthetic.

Further, the skin of the cast metal exhibits a blackish brown color, which is unsatisfactory in appearance.

[0005]

[0009]

[Action]

 The furnace wall and grate form the furnace for incineration, the grate supplies air into the furnace and drops the ash generated by combustion, and the chimney releases the combustion gas in the furnace to the atmosphere. Let it drain. Other functions will be clarified by the following description.

[0010]

【Example】

 FIG. 1 is an overall view showing an incinerator according to an embodiment of the present invention, and FIG. 2 is an exploded view of a pedestal from which a chimney is removed and a furnace wall body in the incinerator.

In the figure, reference numeral 1 denotes a cast pedestal whose outer surface is colored enamel, which comprises a peripheral wall 1a having an ash outlet 2 and a grate 1b formed on the top surface thereof, and the periphery of the grate 1b. Is formed with a step difference portion m, and the main dimensions are a height of about 150 to 250 mm and a diameter of about 350 to 450 mm.

Reference numeral 3 denotes a furnace wall body whose outer surface is similarly colored enamel, and comprises a cast main wall body 4 and a lid body 5.

The cast main wall 4 forms a projecting top wall 4b having a streamlined curved surface continuously with the upper end of a cylindrical vertical wall 4a surrounding the grate 1b, and projects at a high place of the top wall 4b. In addition to providing a chimney connection port 6, a relatively large incinerator input port 7 is provided in the inclined surface portion from the top surface wall 4b to the cylindrical vertical wall 4a, and the whole is integrally formed. A stepped portion 4c for supporting the periphery of the lid 5 is provided around the insertion opening 7.

The lid 5 covers the inlet 7 so that it can be opened and closed. Specifically, the lid 5 is made of an integral casting and has a streamlined shape that follows the inclined surface of the portion of the inlet 7. Further, a hook portion 5a for opening / closing operation is integrally formed at an appropriate position on the outer surface, and a hinge joint portion 4d integrally formed on the main wall body 4 and a hinge joint portion 5b integrally formed on the lid body 5 are provided. Due to the separable fitting, swinging and opening / closing operations around these joint portions 4d and 5b can be freely performed. The lid body 5 is not limited to this, and may be formed of a stainless plate or the like.

Further, the main dimension of the furnace wall 3 is about 500 to 600 mm in height and the diameter is similar to that of the pedestal 1.

Reference numeral 8 denotes a chimney formed of a stainless steel plate or the like, and a tip for preventing rainwater from directly intruding into the tubular body 9 and the tubular body 9 which is fitted to the connection port 6 and the sparks are scattered. It consists of 10 hardware.

When the pedestal 1 and the furnace wall 4 are subjected to enamel processing, these castings are heated to about 1000 ° C. and the required colored glass powder of blue, green, yellow, red, piquic, etc. This is done while sprinkling the material, resulting in a beautiful colored enamel casting.

Next, to explain an example of use of the product of the present invention, at the time of installation, the pedestal 1, the furnace wall 4 and the chimney 8 are separately carried and assembled on a flat ground. This furnace wall body 4 is placed in a state of being fitted to the stepped portion m on the top surface of the pedestal 1.

When incinerating dust, the dust is supplied from the charging port 7 into the furnace wall body 4 and burned. At this time, the presence of the charging port 7 in the inclined surface portion of the furnace wall body 4 facilitates the worker's operation of charging dust as compared with the case where the charging port 7 is on the horizontal top surface.

During combustion, air is sucked in through the ash outlet 2, passes through the grate 1b, reaches the inside of the furnace wall 4, and promotes combustion. Then, the combustion gas in the furnace wall 4 is guided to the inner surface of the furnace wall 4, reaches the chimney 8, and is then discharged to the atmosphere.

Combustion air and combustion gas are compared between the cylindrical vertical wall 4a of the furnace wall 4 and the top wall 4b (including the lid 5) having a streamlined curved surface without generation of a gas retention part. Since it is guided smoothly to the chimney 8, the dust is efficiently burned and incinerated.

Although the combustion gas in the furnace wall 4 often reaches 800 ° C. to 1000 ° C., not only castings but also enamel can withstand this and maintain its beauty forever.

The ash produced by incineration falls from the grate 1 b below the pedestal 1 and is deposited, and the deposited ash is scraped out from the ash outlet 2.

Although the furnace wall 4 may be exposed to rainwater, the top wall 4b having a streamlined curved surface smoothly guides this rainwater to the cylindrical vertical wall 4a side, and also exists on the inclined surface portion. The lid body 5 guides rainwater to the cylindrical vertical wall 4a side more easily than in the case where it is present on the flat surface portion, and reduces the intrusion of rainwater into the furnace wall body 4.

Further, although the furnace wall may be blown by the wind, it remains stable on the pedestal 1 due to the weight of the casting itself.

[0026]

[Effect of device]

 According to the present invention configured as described above, the pedestal, the furnace wall and the chimney are constituent parts, the number of parts is reduced as compared with the conventional one, and the furnace wall is a three-dimensional integrated structure. It reduces manufacturing costs and simplifies handling during manufacturing and assembly. Here, the fact that the furnace wall is a three-dimensional monolithic structure further increases the rigidity and strength of itself and contributes to material savings. In addition, the fact that the main part is made of casting not only excels in combustion efficiency, but also maintains rust prevention and durability from fire resistance for a long period of time, and the furnace wall is a three-dimensional integrated structure with a streamlined curved surface. The fact that it is a projecting top wall and that the inlet is provided on the sloped surface promotes the outflow of rainwater to the outside and prevents rainwater from entering the furnace. In addition, the provision of a charging port on the inclined surface facilitates charging of the incineration material.

According to the second aspect of the present invention, the lid smoothly guides the flow of the combustion gas and has durability in terms of fire resistance and rust prevention.

According to the third aspect of the present invention, even if it is placed in the garden, it does not spoil the aesthetics, so that it can be installed without selecting a place. Since the enamel is baked at 1000 ° C, it is not damaged by burning at around 800 ° C, and its beauty can be maintained semipermanently.

According to the fourth aspect, the size of the furnace is suitable for home use, and the size and weight of the pedestal and the main wall are suitable for manual work.
