A heating plate body 31 whose lower surface is
It is installed at a required interval from the boundary wall 48.

Furthermore, a space 10' between the upper combustion chamber 8 and the coal storage chamber 5
A corresponding upper part of the humidifier 40 has a steam outlet 9 at the upper end, and an air preheating chamber 27 having the forced injection port 28 is provided between the bottom wall 44 of the humidifier 40 and the lower combustion chamber 3. Make it compose.

In the figure, 4 is a lid, and 7 is an exhaust hole leading to a chimney.

The coal feeding means 45 includes a feeding piece 14 having a chevron-shaped protrusion 13 at its front end so as to be movable back and forth, a bracket 15 below the feeding piece 14, and a crank plate rotated by a gear motor 0M or the like. Both ends of the crank rod 17 are connected between the crank rod 16 and the crank rod 16.

It is assumed that the speed of this gear motor GM can be adjusted with a speed adjustment dial 38.

A movable loss dollar 19, 20° 21, whose rear end can stand up and rotate around a pivot 18 at the front end, is placed between the rear end of the loss dollar 12 and the middle part of the rear wall of the combustion chamber 3. 1
1 and Rosdol 12, and movable Rosdol 19, 20, 2
1 are arranged in a substantially downward arc shape, and at the ends of the pivot shafts 18 of the movable loss dollars 19, 20, 21 outside the combustion chamber 3,
An actuation lever 22.23.24 is provided.

33 is an ash receiving box installed on the bottom 34 inside the combustion chamber 3.

The present invention has the above-mentioned configuration, and one side of the coal stove has the following parts as shown in FIG. 1 and FIG.

etc. (see the wiring diagram shown in the third figure).

Therefore, prior to use, the shutter plate 25 on the rear wall of the coal storage chamber 5 is pushed down by operating the operating piece 26 to a position where its lower end touches the middle of the loss dollar 12, and By operating the operating lever 22 attached to the end of the pivot shaft 18 of the movable loss dollar 19, the movable stopper integral 46 is actuated (in the drawings, the movable loss dollar 19
(in an upright position), and the necessary amount of coal is put into the coal storage chamber 5, on the loss dollar 12, the feeding piece 14, on the guide plate 11, and in the coal storage chamber 5.

After that, when the shutter plate 25 is raised, the coal storage chamber 5
The coal inside is supplied to the front of the movable Rosdol 19 in the upright position in the lower combustion chamber 3 and onto the Rosdol 12. At this time, the piezoelectric ignition type gas cock dial 36
to ignite the gas burner 2, set the timer dial 37 to about 5 to 10 minutes, and also turn on the gear motor switch 39 and fan motor switch 40'.

In this way, the gas flame from the gas burner 2 causes the coal deposits deposited on the movable rosdol 12 to be sufficiently heated and combusted since the movable rosdol 19 at the front acts as a stopper to prevent the coal from advancing. Because it becomes
When the set time on timer dial 37 approaches,
When the gas supply to the gas burner 2 is cut off, and then the operating lever 22 is operated to return the movable loss dollar 19 at the front around the axis to release the stopper role, the area above and below this movable loss dollar 19 is released. Rear movable Rosdol 2

A small amount of air is intermittently sent to the rear, and the fan motor FM also operates to start supplying air into the air preheating chamber 27 and to the rear of the triangular cross-sectional protrusion 29 located below the air preheating chamber 27 diagonally downward. Secondary air flows from the forced jet port 2B opened into the lower combustion chamber 3 into the movable loss dollars 19, 20.2.
It is sprayed onto the surface layer of the coal pile on top of No. 1 to fully burn the coal.

The combustion flame of this coal enters the upper combustion chamber 8 through the ventilation hole 30, and the combustion gas is discharged from the exhaust hole 7 at the upper rear part of the upper combustion chamber 8.
Above the ventilation hole 30 at the lower inner end, a heating plate 31 whose lower surface is bulged in an arc shape is horizontally installed so as to be ventilated through spacers 32 and 32, so that the combustion flame is transmitted through the ventilation hole 3.
0 and hits the arcuate bulging surface 49 on the lower surface of the heating plate 31,
The soot dust and incomplete combustion gas contained in the combustion gas are combusted by the red-hot heating plate 31, and the gas passes from the bottom of the heating plate 31 upwards, so that the peripheral wall of the upper combustion chamber 8 is sufficiently heated, and the stove is heated by this heat radiation. It will fully fulfill its functions.

Since the coal stove device according to the present invention has good thermal efficiency, only a small amount of coal can be used.Moreover, since the automatic coal feeding means 45 is built-in, the coal stove device according to the present invention can continuously supply the necessary amount of coal to the combustion chamber 3 for a long time. Coal is sent to the required locations and can be combusted rationally without requiring any human intervention, resulting in so-called smokeless combustion, allowing it to fully function as a stove.
