Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a baking device such as an oven, a fish grilling device, a meat grilling device, etc.

(Prior Art) There are known conventional kilns that burn out the heat source for smoke kiln before releasing the smoke generated during kiln to the outside.
(See Publication No. 783).

(Problem to be Solved by the Invention) By the way, smoke generated during cooking is better when the heat source for cooking is both the heat source for the upper heat and the heat source for the lower heat, rather than just one of the heat source for the upper heat or the heat source for the lower heat. Even if there are many heat sources, or only a heat source for the top heat or a heat source for the bottom heat,
Cooking using a heat source for lower heat generates more smoke, or the amount of smoke generated varies depending on the type of food, such as fish, to be cooked. Therefore, if the strength of the heat source for smoke grilling is set uniformly, and if the strength of the heat source for smoke roasting is set in anticipation of a situation where there will be a lot of smoke, then if there is little smoke generated during cooking, the heat energy will be reduced. If the strength of the heat source for smoke burning is set in anticipation of a case where there will be no waste or little smoke, there is a problem that if there is a lot of smoke generated during cooking, the smoke will not be burnt sufficiently.

(Means for Solving the Problems) The present invention is intended to solve the above-mentioned disadvantages, and is directed to providing a heating source for cooking in the baking chamber and emitting smoke generated from the food to be cooked during baking to the outside. In the case where a heat source for smoke combustion is provided in the exhaust passage, a plurality of heat sources for smoke combustion are provided so as to be able to operate independently of each other, and the plurality of heat sources for smoke combustion are arranged back and forth in the flow direction of smoke. It is characterized by having been provided.

(Function) The present invention has the above configuration, and according to this, when the smoke generated from the food to be cooked is relatively small, for example when only the heat source for the top flame is used, one Activate the heat source to burn the smoke as it exits. Also, when there is usually a relatively large amount of smoke generated from the food being cooked, such as when both the heat source for the upper heat and the heat source for the lower heat are activated, multiple heat sources for roasting are activated. Burn it while it is being discharged. In this case, it is preferable if the plurality of heat sources for burning smoke are arranged facing each other instead of being arranged one behind the other in the direction of smoke flow, since the hot air will interfere with each other and this will impede the flow of smoke in the smoke exhaust passage. However, in the present invention, a plurality of heat sources for burning smoke are arranged one behind the other in the direction of smoke flow, for example, or arranged in a staggered manner in the direction of smoke flow. Since the hot air does not interfere with each other, the flow of smoke is not obstructed by the hot air.

(Example) Next, an example in which the present invention is applied to a gas stove with a kiln will be described based on the drawings.

In the drawing, 1 is the main body of the gas stove, 2 is a baking device installed therein, 3 is a top burner which is a heat source for baking the food to be cooked in the baking chamber 2a of the baking device 2 from the top, and 4 is the cooking device. A bottom burner 5 is a heat source for cooking the food X from the bottom surface thereof, and 5 indicates a smoke exhaust passage connected to the baking chamber 2a.

The upper burner 3 was a surface combustion type gas burner, and the lower burner 4 was a Bunsen type gas burner.

In the baking machine having such a configuration, the smoke exhaust passage 5 is provided with a heat source for combustion in multiple compartments that operates according to the amount of smoke generated from the food to be cooked. If the two are arranged vertically opposite each other, the hot air will interfere with each other and hinder the flow of smoke, which is undesirable. Therefore, the height of the smoke exhaust passage 5 must be increased to prevent interference. When there is little smoke generated from the food to be cooked X and only one of the heat sources for smoke burning is activated, the height of the smoke exhaust passage is too high and the smoke cannot be burnt sufficiently.

In order to solve the above-mentioned inconvenience without increasing the height of the smoke exhaust passage 5, the present invention provides a plurality of heat sources for smoke burning in the smoke exhaust passage 5 so as to be operable independently of each other. This is characterized by the fact that a plurality of heat sources for smoke burning are provided in front and behind each other in the flow direction of the smoke. A smoke burning burner 6 for the top burner 3, which uses a surface combustion type gas burner as a heat source.
₁ and a smoke burning burner 6 ₂ for the bottom burner 4, and both smoke burning burners 6 ₁ and 6 ₂ are arranged in front and back in the smoke flow direction on the upper wall of the smoke exhaust passage 5, The flame spreading surfaces of the combustion burners 6 ₁ and 6 ₂ were made not to face each other.

Top burner 3, bottom burner 4, and smoke burner 6
The gas control circuit for the combustion burner ₁ and the combustion burner 6 _{and 2} is as shown in FIG. and an on-off valve 10, and a gas supply path 11 connected to the smoke burner 6 ₁ and the smoke burner 6 _{2 .}
An on-off valve 13 that opens and closes in conjunction with the opening and closing of the on-off valve 9 and an on-off valve 14 that opens and closes in conjunction with the opening and closing of the on-off valve 10 are interposed in the gas supply path 12 connected to the on-off valve 9, so that the on-off valve 9 opens. Then, the on-off valve 13 opens, and the upper burner 3 burns, resulting in top heat heating, and the smoke burner ₆₁ burns, resulting in weak combustion. Or on-off valve 10
opens, the on-off valve 14 opens, and when the bottom burner 4 burns, the bottom heat is heated and the smoke burner 6 ₂
This results in weak combustion. Also, both on-off valves 9, 10
When it opens, both on-off valves 13 and 14 open, and both the upper and lower burners 3 and 4 burn, resulting in heating on both the upper and lower sides, and both the burners 6 ₁ and 6 ₂ burn, resulting in strong combustion. I made it.

In this case, when only the upper burner 3 or the lower burner 4 is used, there is not much smoke generated from the food X in the oven 2, so the burner ₆₁ or Even if only burner 6 ₂ is burned, the smoke can be reduced by burning, and when both upper and lower burners 3 and 4 are burned, a large amount of smoke is normally generated from food X, so in this case both smokes The combustion burners 6 ₁ and 6 ₂ can be used to burn and reduce the smoke, and in either case, the smoke is not directly released to the outside.

FIG. 5 shows another embodiment in which the present invention is applied to a gas stove with a burner, in which a smoke burner 6 ₁ and a smoke burner 6 ₂ are placed in the smoke exhaust passage 5 back and forth in the smoke flow direction. 1 to 4, except for the fact that the upper and lower walls are arranged in a staggered manner so that the combustion surfaces of both the combustion burners 6 ₁ and 6 ₂ do not face each other. It is not particularly different from the embodiment.

In the above two embodiments, it is assumed that when both the upper and lower burners 3 and 4, which are heat sources for cooking, are burned, a large amount of smoke is generated from the food to be cooked. Burner 6 ₁ for double smoke burning, which is the heat source of
I tried to reduce the smoke by burning 6 ₂ , but
For example, even when only the heat source for lower heat, which is the heat source for cooking, is activated, a large amount of smoke may be generated depending on the type of food to be cooked. In such a case, a plurality of heat sources for burning smoke may be operated to burn the smoke and reduce the amount of smoke. That is, when only the lower burner is in combustion, the bypass valve 13a of the bypass passage 11a, which is provided in parallel with the on-off valve 13 of the smoke burning burner ₆₁ , can be opened and closed as necessary.

According to the two embodiments described above, when a large amount of smoke is generated during firing, such as when both the upper and lower burners 3 and 4 are burned, both smoke burning burners 6 ₁ and 6 ₂ are burned to eliminate the smoke. When burning effectively, the combustion surfaces do not face each other and the thermal pressures do not interfere with each other, so there is no need to increase the height of the smoke exhaust passage ₅ .
The flow of exhaust gas from the smoke exhaust passage 5 is not obstructed by the thermal pressure of 6 ₂ , and when the heat source for combustion is a burner as in this embodiment, both burners 6 ₁ and 6 ₂ are used. burns well without flashback.

In addition, in the above two embodiments, the upper burner 3
Although the burner ₆₁ , the lower burner 4, and the burner ₆₂ are each constructed as separate burners, they may each be constructed as an integrated burner, as shown in FIG. In this case, the top burner 3 and the smoke burner 6
₁ , the lower fire burner 4, and the smoke burning burner ₆₂ are each integrated, so they are interlocked. In this example, the part facing the smoke exhaust passage 5 formed by the projecting piece 5a protruding into the firing chamber 2a of the burner B is the smoke firing burner 6.
It becomes ₁ .

In addition, even when the heat source for the upper heat and the heat source for the lower heat are activated, smoke may not be generated depending on the type of food You may also make it stop.
That is, by using a control circuit as shown in FIG. 8, the on-off valves 13 and 14 of the smoke burning burners 6 ₁ and 6 ₂ may be controlled as necessary.
Alternatively, even when only the lower burner 4 is being burned, both the smoke burning burner 6 ₁ and the smoke burning burner 6 ₂ can be burned.

At this time, the smoke may be reduced by burning the smoke burners 6 ₁ and 6 ₂ in response to a smoke amount signal from a smoke sensor provided near the entrance of the smoke exhaust passage 5, for example.

FIGS. 9 and 10 show still another embodiment. In this example, the heat source for cooking is only the lower burner 4, and the smoke burners 6 ₁ and 6 ₂ are set according to the amount of smoke generated. , stop of both smoke burners 6 ₁ and 6 ₂ , combustion of one smoke burner, and combustion of both smoke burners 6 ₁ and 6 ₂ can be controlled.

Incidentally, in all the embodiments described above, a burner was used as a heat source for cooking and a heat source for smoking, but an electric heater may also be used.

(Effects of the Invention) According to the present invention, when providing a plurality of heat sources for smoke combustion in the smoke exhaust passage, the heat sources are arranged back and forth in the direction of smoke flow so that the fire power can be changed according to the amount of smoke generated. Because the amount of smoke generated from the food to be cooked is large and two or more heat sources for smoke grilling are activated, they are operated so that the hot air does not interfere with each other and the flow of smoke is not obstructed. This has the effect that the heat source for cooking can be burned without waste while the heat source for cooking always works well.
