It is a principal part longitudinal cross-sectional view of an oven. It is a perspective view which shows the procedure which mounts an oven in a wood-burning stove. FIG. 4 is a vertical cross-sectional view showing the flow of combustion smoke during operation of a wood-burning stove.

An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 7. FIG.
<Configuration of Embodiment>
As shown in FIG. 1, a wood stove 1 in which additional equipment is set has a wood stove oven 2 as a cooking utensil mounted on the top surface and a boiler 3 as a hot water generator mounted on the back surface. A chimney 4 extending toward the ceiling from a chimney port 41 passing through the upper part is attached to the wood-stove oven 2 . The wood stove with an oven includes a wood stove 1 and an oven 2 for the wood stove.

The wood-burning stove 1 includes a stove main body 11 which is a steel plate welded structure and has a substantially rectangular parallelepiped shape, and a cast door 12 attached to the front surface of the stove main body 11 to form an outer shell 21a. In the stove body 11, a secondary combustion adjusting lever 13 is arranged on the lower right side, a primary combustion adjusting lever 14 is arranged on the lower left side, and a roster driving lever 15 for dropping ash into the ash tray below is arranged on the right side. placed on the surface. The top plate 16 of the stove main body 11 is formed of a relatively thick (for example, 10 mm) steel plate, and when used alone (without the wood stove oven 2 mounted), it can be used for boiling water in a kettle or the like or cooking in a frying pan or the like. can be done. Further, legs 11a are integrally extended from the lower end of the stove main body 11 to the four corners. On the other hand, the door 12 is provided with a door glass 12a for checking the burning state of firewood and a door handle 12b for opening and closing the door 12 when loading firewood.

The wood-burning stove oven 2 includes an oven main body 21 having a substantially rectangular parallelepiped shape and a door 22 attached to the front surface of the oven main body 21 to form an outer shell 21a. Both the oven body 21 and the door 22 are steel plate welded structures. Hollow chambers 26a to 26d (see FIG. 4 to be described later) communicating with each other are formed in the upper, lower, left, right, and rear sides of the oven body 21. As shown in FIG. The top plate 23 of the oven main body 21 is made of the same steel plate as the top plate 16 of the stove main body 11, and the upper surface thereof can be used for boiling water with a kettle or the like and cooking with a frying pan or the like. On the other hand, the door 22 is provided with a door glass 22a for checking the cooking state, and a door handle 22b for opening and closing the door 22 when the food is added. The wood stove oven 2 preferably has a detachable rear panel in order to facilitate cleaning of the inside of the oven.

As shown in FIG. 2 , when the wood stove 1 is used alone, the chimney 4 is attached to the upper surface of the top plate 16 via the chimney port 42 . As shown in FIG. 3, the top plate 16 is formed with a guide hole 17 into which an inner flange type chimney port 42 is fitted, and an annular bracket 18 facing the inner flange 43 of the chimney port 42 is welded to the lower surface. there is In the case of this embodiment, the space surrounded by the bracket 18 serves as the combustion smoke exhaust port 19 . Three mounting pieces 43a extend at equal angular intervals inside the inner flange 43 of the chimney port 42, and each of these mounting pieces 43a is provided with a screw hole 43b.

Three mounting pieces 19a corresponding to the mounting pieces 43a of the inner flange 43 extend inside the combustion smoke discharge port 19, and these mounting pieces 19a are provided with through holes 19b, respectively. The chimney port 42 is firmly fastened to the top plate 16 (bracket 18) with three bolts 45 inserted through the through hole 18b and the screw hole 43b. A ring-shaped glass fiber rope 47 made of woven glass fiber is attached to the outer periphery of the guide hole 17 in order to prevent combustion smoke from leaking from between the top plate 16 and the chimney port 42 . As shown in FIG. 5, the glass fiber rope 47 is attached to the inner side of a leg projecting about 5 mm downward from the outer edge of the lower surface of the oven body 21 . The glass fiber rope 47 has a height dimension larger than that of the legs and protrudes below the lower end of the frame when no external force is applied.

As shown in FIG. 4, a combustion smoke introduction port 25 for introducing combustion smoke into the hollow chambers 26a to 26d is formed through the lower portion of the outer shell 21a. Three mounting pieces 25a extend inside the combustion smoke inlet 25 in a manner corresponding to the combustion smoke discharge port 19 of the bracket 18 described above, and each of these mounting pieces 25a is provided with a screw hole 25b. .

As shown in FIG. 5, the oven body 21 has a double structure consisting of an outer shell 21a and an inner shell 21b. An object to be heated such as cooking is placed in the inner shell 21b. The outer shell 21a covers the outside of the inner shell 21b. An upper hollow chamber 26a, a lower hollow chamber 26b, a left hollow chamber 26c, a right hollow chamber 26d, and a back hollow chamber (not shown) are defined between the outer shell 21a and the inner shell 21b. These hollow chambers communicate with each other, and the combustion smoke inlet 25 communicates with the lower hollow chamber 26b, and the chimney port 41 communicates with the upper hollow chamber 26a.

<Action of Embodiment>
When mounting the wood stove oven 2 on the existing wood stove 1 (see FIG. 2), the chimney 4 and the chimney port 41 are first removed, and then the wood stove oven 2 is placed on the upper surface of the top plate 16 . Next, the wood stove is positioned so that the combustion smoke inlet 25 (see FIG. 4) is positioned directly above the combustion smoke outlet 19 (that is, so that the through hole 19b and the screw hole 25b are positioned on the same line). Adjust the position of the cooking oven 2.

After that, open the door 12 of the wood stove 1, insert the bolt 45 (see FIG. 3) from below the top plate 16 into the through hole 19b, and tighten it into the screw hole 25b with a predetermined tightening torque. As a result, the wood-stove oven 2 is securely fastened to the wood-stove 1, and the glass fiber rope 47 is deformed (crushed) and brought into close contact with the bottom plate 24 of the oven main body 21 and the top plate 16 of the wood-stove 1. - 特許庁

After the installation of the wood stove oven 2 on the wood stove 1 is completed, as shown in FIG. complete.

When the burning material such as firewood is put in and the operation of the wood stove 1 is started, high-temperature combustion smoke is continuously generated in the stove main body 11 . As shown in FIG. 7, the combustion smoke rising inside the stove main body 11 flows from the combustion smoke discharge port 19 of the top plate 16 into the combustion smoke introduction port 25 of the oven main body 21 and passes through the hollow chambers 26a to 26d. It is later discharged into the chimney 4. As a result, the internal temperature of the oven 2 for the wood-burning stove rises sharply, and food such as pizza can be cooked at a high temperature. In addition, since the top plate 23 of the oven 2 for the wood-burning stove also reaches a high temperature, it is possible to boil water using a kettle and cook various dishes using frying pans and pots. In addition, since the boiler 3 is attached to the wood stove 1, by supplying the hot water generated by the boiler 3 to a floor heating or a hot water type panel heater, it is possible to heat a place away from the wood stove.

The description of the specific embodiments is finished above, but the aspect of the present invention is not limited to this, and the specific structure of the wood stove or the oven for the wood stove, the method of connecting each element, etc. can be changed as appropriate as long as it does not deviate from
