Consists of

(Operation) In the firing cabinet according to claim 1, which has the above-mentioned configuration, since the relatively small smoke discharge gap is formed on the upper surface by the projecting piece, the smoke generated in the firing cabinet is the smoke. When it passes through the discharge gap, it is burned to be smokeless and odorless, and since the projecting piece is composed of a heat-transmitting body, the heat is transmitted therethrough and the heat is also transmitted to the lower side of the projecting piece. You can bake food.

Further, in the firing chamber according to claim 2, the smoke is similarly burned when passing through the smoke discharge gap to be smokeless and odorless, and
When the thermal radiator is heated by the heating source, it releases heat to the lower rear part of the baking chamber. By this heat, the food to be cooked located at the rear of the baking cabinet can be baked.

Further, in the baking cabinet according to claim 3, when smoke passes through the smoke discharge gap, it is burnt to be smokeless and odorless, and at the same time, from the heating source for cooking through a through hole provided in the projecting piece. Heat can be applied to the lower rear part of the baking cabinet. By this heat, the food to be cooked located at the rear of the baking cabinet can be baked.

(Example) An example in which one example of the present invention is applied to a stove with a calciner will be described.

In the drawing, reference numeral 1 denotes a baking cabinet provided in a device main body 2. The baking cabinet 1 has an opening 3 in its front surface, the opening 3 is provided with an openable / closable door 4, and an upper part in the baking cabinet 1 Is provided with a heating source 5 for cooking, and a smoke exhaust passage 6 is provided in the upper rear part in the baking cabinet 1.

According to the present invention, in the embodiment shown in FIGS. 1 to 4, smoke discharge communicating with the smoke discharge passage 6 between the inside of the baking chamber 1 and the lower surface of the cooking heating source 5 is performed. A plate-shaped heat-resistant glass plate is projected as the protruding piece 8 made of a heat-transmitting body with a gap 7, and this will be described in more detail.
The baking cabinet 1 is composed of an upper member 1a and a container-shaped lower member 1b, and the upper member 1a has an opening 1a for attaching a gas burner as a heating source 5 for cooking which covers substantially the ceiling surface of the baking cabinet 1 at the substantially center thereof. -1 is provided with a flat plate portion 1a-2 and a cylinder portion 1a-3 that constitutes the smoke discharge passage 6 are integrally formed behind the flat plate portion 1a-2. The guide rails 1b-4, 1b-4 are provided so as to be drawn out, and the opening 3
Is provided at the front end of the lower member 1b, and the door 4 for closing the lower member 1b is integrally attached to the front end of a soup saucer 9 provided on the lower member 1b so as to be housed in the baking cabinet 1. At this time, the opening 3 was closed. Then, the projecting piece 8 made of the heat-transmitting body is attached to the front end of the tubular portion 1a-3, and the smoke discharging gap communicating with the smoke discharging passage 6 is provided between the upper surface thereof and the rear lower surface of the cooking heating source 5. 7 was formed.

The gas burner as the heating source 5 is a gas burner body.
Ceramic board 5c with many flame openings 5b in the bottom opening of 5a
The ceramic plate 5c is formed by attaching a large number of flame ports 5b in the portion facing the projecting piece 8 to increase the amount of heat in the portion, and the remaining portion is not formed in the center thereof. Flame mouth
5d is provided so that heat can be spread over a wider area with a predetermined number of flame openings 5b. It should be noted that the amount of heat of the portion facing the projecting piece 8 can be increased by increasing the diameter of the flame port.

In this case, smoke generated from the food to be cooked a in the baking cabinet 1 passes through a relatively narrow smoke discharge gap 7 formed between the projecting piece 8 and the heating source 5 for cooking, and a smoke discharge passage. The smoke is discharged to the side 6 and when passing through the narrow smoke discharge gap 7, the smoke is burnt by the heat from the cooking heating source 5 to be smokeless and odorless.

Moreover, the heat from the cooking heating source 5 passes through the glass plate serving as the projecting piece 8 and reaches the lower portion of the rear part of the baking cabinet 1, whereby the rear part of the cooking heating source 5 burns smoke. Even if the projecting piece 8 is provided to be used as a heat source for the above, the rear part of the baking chamber 1 can be sufficiently heated.

In the embodiment shown in FIG. 5, the cooking heating source 5 is provided in the baking chamber 1.
The protruding piece 8 is projected with a smoke discharging gap 7 communicating with the smoke discharging passage 6 between the lower surface and the lower surface, which is the same as the above-mentioned embodiment, but the protruding piece 8 is relatively fine. A heat radiating body made of heat-resistant wire netting, and in this case, smoke generated in the baking chamber 1 in the smoke discharge gap 7 formed between the wire netting and the heating source 5 for cooking as described above. Can be burned to make it smokeless and odorless, and also part of the smoke flowing as indicated by the arrows between the wire nets that are red-heated by the cooking heating source 5 can be burnt.

When the wire net is heated by the cooking heating source 5, the heat radiated from the wire net exerts heat on the rear portion of the baking chamber 1 as in the above-described embodiment.

FIG. 6 shows still another embodiment, in which the fifth embodiment
Similar to the embodiment shown in the figure, the heating source 5 for cooking is used as the protruding piece 8.
A heat radiating body that is heated when it receives more heat and emits heat, for example, a heat-resistant metal plate is used, and the smoke discharge gap 7 formed between it and the cooking heating source 5 on the upper surface thereof is formed in the same manner as described above. When smoke passes, it can be burned to make it smokeless and odorless, and at the same time, the rear part of the baking oven 1 can be heated by the heat radiated when the metal plate is heated.

In FIGS. 7 and 8, a stainless plate is used as the projecting piece 8, several through holes 8a are formed in the stainless plate, and the heat from the heating source 5 for cooking on the upper surface of the stainless plate is passed through the through holes 8a. It was supplied to the rear part of the firing chamber 1 via the.

When doing so, when smoke passes through the smoke discharge gap 7 formed between it and the cooking heating source 5 on the upper surface thereof as described above, it is burned to make it smokeless and odorless, and through the through hole 8a. Thus, heat can be supplied to the rear part of the firing chamber 1.

Incidentally, in this embodiment, the stainless plate is provided with a pair of left and right side walls 10,
Behind 10 and to the rear of the smoke exhaust passage 6, that is, the device body 2
The standing wall 1a-4 of the tubular portion 1a-3 formed integrally with the gas burner body 5a is also made of stainless steel while being extended to a position facing the lower surface of the exhaust port 6a opened on the rear upper surface. As a result, the red heat light from the cooking heating source 5 is reflected, and it can be confirmed from the exhaust port 6a that the baking cabinet 1 is in use.
That is, it is a rear exhaust type, and it is difficult to confirm whether it is cooking with an odor even when cooking by making it smokeless and odorless, and in the case where it is provided near the waist height of a person like a stove,
Although it is troublesome to confirm the state of cooking from the front door 4, if this is done, the confirmation can be made only by looking at the exhaust port 6a from above during cooking. Further, in this embodiment, the blocking members 11 are provided on both sides of the projecting piece 8 so that the smoke passes only below the cooking heating source 5. More specifically, the heating source 5 for cooking is not in the entire width of the baking chamber 1, that is, the heating source 5 for cooking presses the ceramic plate 5c that constitutes the combustion surface on both sides of the heating plate 5e.
Therefore, the ceramic disc 5c is not full width. For this reason, if smoke passes through here, there is a possibility that smoke will be emitted outside without being burned by the heat from the cooking heating source 5.
Therefore, both sides without the ceramic board 5c were closed by the closing member 11. However, in this case, only the position corresponding to the rearmost portion of the cooking heat source 5 on both sides without the ceramic board 5c is covered with the standing wall, and some smoke is present at the inlet side of the smoke discharge gap 7 to the cooking heat source. You may make it flow in from the part without 5.

In this sense, it can be said that the protruding piece 8 only needs to be located under the cooking heating source 5 and that the protruding piece 8 does not function where the ceramic disks 5c forming the combustion surfaces on both sides are absent. FIG. 9 shows still another embodiment. In this embodiment, a heat source 51 dedicated to smoke burning is provided above the projecting piece 8 separately from the heating source 5 for cooking.
In this case, the heat from the heat source 51 dedicated to the smoky grill can also be used as the heat for cooking. That is, since the heat from the heat source 51 dedicated to the smoldering can be used as the heat for cooking, the baking cabinet 1 can be used more greatly, and the heat source 51 dedicated to the smoldering can be independently controlled, and only when necessary. Dedicated heat source for smoke grill
There is an advantage that 51 can be used.

In this embodiment, as the projecting piece 8, a stainless plate similar to that shown in FIGS. 7 and 8 is provided with several through holes 8a, and heat from a heat source 51 for exclusive use of smoke burning on the upper surface thereof is applied to the through holes. The one that was supplied to the rear part of the baking cabinet 1 via 8a was used. However, the present invention is not limited to this, and it is needless to say that a heat-transmitting body such as a glass plate shown in FIG. 1 or a heat-radiating body such as a wire mesh shown in FIGS. 5 and 6 can be used as the projecting piece 8. . Further, in the above embodiment, the surface combustion type gas burner is shown as the heating source 5 for cooking, but it is needless to say that this may be a Bunsen type gas burner, or an electric heater or other heater. .

If the protruding piece is a heat-transmitting body such as glass or a heat-radiating body such as a wire mesh, the smoke exhaust passage 6 cannot be constructed with these, but as shown in FIGS. 7 and 9, the protruding piece 8 is made of metal. In the case of a plate, the projecting piece 8 can be integrated with the lower member of the smoke discharge passage 6 to simplify the structure.

From this, it can be said that the smoke exhaust passage 6 is exposed to the heating source.

(Effects of the Invention) Since the present invention is configured as described above, it has the effects described below.

In the baking oven according to claim 1, when the smoke generated in the baking oven passes through the smoke discharge gap formed between the protrusion made of the heat-transmitting body and the rear part of the heating source for cooking, it is burned. The smoke is made odorless and odorless, and the heat from the cooking heating source can be spread to the lower rear part of the baking chamber through the protrusion, and the rear part of the cooking heating source is used as a heat source for burning smoke. Therefore, even if the projecting piece is provided, heat for cooking the object to be cooked can be applied to the rear portion of the baking oven.

In the firing chamber according to claim 2, the smoke generated in the firing chamber is fired to make it smokeless and odorless. This is the same as the firing device according to claim 1, but in this one, the protrusion is When the heating source for cooking is heated, it is possible to heat the lower rear part of the baking chamber by the heat radiation emitted from the heating source, and to provide a protrusion for using the rear part of the heating source for cooking as a heating source for burning smoke. Also, heat for cooking an object to be cooked can be applied to the rear part of the baking chamber.

In the firing chamber according to claim 3, the smoke generated in the firing chamber is fired to make it smokeless and odorless. The heat from the heating source for cooking can be applied to the lower rear part of the baking cabinet through the through hole provided, and the heat can be used to bake the food to be cooked located in the rear part of the baking cabinet.
