Abstract

PURPOSE:To enable a cooking heating source to be effectively operated and ignite a burning heating source without any useless state by a method wherein a plurality of igniting heating sources are independently arranged in such a way as they can be operated and a plurality of smoke burning heating sources are arranged after and before a smoke flowing direction. CONSTITUTION:Smoke burning burners 61 and 62 are arranged after and before at an upper wall of a smoke discharging passage 5 in a smoke flowing direction in parallel to each other and the combustion surfaces of both smoke igniting burners 61 and 62 are not oppositely faced. When only the upper flame burner 3 is ignited or when a lower flame burner 4 is ignited, a few smoke is generated from the cooked item X a baking housing 2, so that either the igniting burner 61 or the igniting burner 62 is ignited to burn the smoke and the smoke is reduced. When both upper and lower burners 3 and 4 are ignited, a large amount of smoke are generated from the cooked item X, so that in this case, both smoke burning burners 61 and 62 are ignited to burn the smoke, the smoke can be reduced and then in any case, the smoke may not be discharged out of the unit as it is.

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) As a conventional firing device, there is a known one that burns out the heat source for burning the smoke before releasing the smoke generated during firing to the outside (for example, see Japanese Utility Model Publication No. 47-783). ).

(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 you use only the heat source for the top heat source or the heat source for the bottom heat, cooking with the heat source for the bottom heat generates more smoke, or the amount of smoke generated depends on the type of food such as fish being cooked. It changes.

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 you set the strength of the heat source for smoke burning in anticipation of a situation where there will be no waste or little smoke, if there is a lot of smoke generated during cooking,
There is an inconvenience that the smoke does not burn sufficiently.

(Means for Solving the Problems) The present invention aims to solve the above-mentioned disadvantages, and includes:
In the case where a heat source for cooking is placed facing the baking chamber and a heat source for cooking is provided in a smoke exhaust passage that discharges smoke generated from the food to be cooked to the outside during baking, a plurality of heat sources for combustion are installed independently of each other. It is characterized in that the plurality of heat sources for combustion are provided in front and behind each other in the flow direction of smoke.

(Function) The present invention has the above configuration, and according to this, when the smoke generated from the food to be cooked is usually relatively small, such as when only the heat source for the top flame is used, one combustion Activate the heat source to burn the smoke as it exits. Also, for example, when using both the heat source for the upper heat and the heat source for the lower heat,
When there is usually a relatively large amount of smoke generated from the food being cooked, multiple combustion heat sources are activated to burn the smoke while it is being discharged. In this case, if multiple heat sources for combustion are placed facing each other instead of being placed one behind the other in the direction of smoke flow, the hot air will interfere with each other, which is undesirable as it will impede the flow of smoke in the smoke exhaust passage. However, in the present invention, a plurality of heat sources for combustion are arranged one behind the other in the direction of smoke flow, for example, or arranged in a row in the direction of smoke flow. Since they are designed not to interfere with each other, the flow of smoke is not obstructed by 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 gas stove main body, 2 is the firing device attached to it,
Reference numeral 3 denotes an upper burner that serves as a heat source for baking the object X in the baking chamber 2a of the baking device 2 from the upper surface thereof, and 4 indicates a lower burner that serves as a heat source for baking the object X from the lower surface thereof. , 5
indicates a smoke exhaust passage connected to the firing chamber 2a.

The upper fire bar 63 was composed of a surface combustion type gas burner, and the lower fire burner 4 was composed of a Bunsen type gas burner.

In the baking machine having such a configuration, the smoke exhaust passage 5
In this method, a plurality of combustion heat sources are provided, which operate according to the amount of smoke generated from the food to be cooked. Therefore, it is necessary to increase the height of the smoke exhaust passage 5 to avoid interference, and by doing so, the smoke emitted from the food to be cooked is reduced and the heat source for combustion is reduced. When only one side is activated, the height of the smoke exhaust passage is too high and the smoke cannot be burned sufficiently.

In order to solve the above-mentioned disadvantage without increasing the height of the smoke exhaust passage 5, the present invention provides the smoke exhaust passage 5 with a plurality of heat sources for combustion that can be operated independently of each other, and This is characterized by the fact that heat sources for combustion are provided one behind the other in the direction of smoke flow.This will be described in detail with reference to the embodiments shown in FIGS. 1 to 4. Combustion burner 6 for upper burner 3 consisting of a combustion type gas burner
1 and a combustion burner 62 for the lower burner 4, both smoke combustion burners 616□ are arranged in front and back in the smoke flow direction on the upper wall of the smoke exhaust passage 5, and both smoke combustion burners 616□ so that the combustion surfaces of the two do not face each other.

The gas 1 control circuit of the upper burner 3, the lower burner 4, the combustion burner 61, and the combustion burner 6□ is as shown in FIG. An on-off valve 9 and an on-off valve lO are interposed in a gas supply path 8 connected to the burner 4, and a gas supply path 11 connected to the combustion burner 6I.
and the gas supply path 12 connected to the combustion burner 62, an on-off valve 13 that opens and closes in conjunction with the opening and closing of the on-off valve 9, and the on-off valve 1.
An on-off valve I4 that opens and closes in conjunction with the opening and closing of 0 is interposed, and when the on-off valve 9 opens, the on-off valve 13 opens, and the top burner 3 burns, resulting in top heat heating, and the combustion burner 61 starts combustion. This results in weak combustion. Or when opening/closing #10 opens, opening/closing valve 14
opens, resulting in lower heat heating in which the lower burner 4 burns, and weak combustion in which the combustion burner 6□ burns. Also, when both on-off valves 9.10 open, both on-off valves I3 and I4 open, and the upper and lower burners 3.4 burn, heating the upper and lower sides, and both smoke burners 6 and 6□ burn. It was designed to produce strong combustion.

In this case, when only the upper burner 3 is used for combustion, or when only the lower burner 4 is used for combustion, there is usually not much smoke from the food Even if only burner 6□ is burned, the smoke can be reduced by burning, and when the upper and lower burners 3.4 are burned, a large amount of smoke is usually generated from food X, so in this case, both burners The smoke can be reduced by burning the burner 61.6□, and in any case, the smoke will not be released to the outside as it is.

FIG. 5 shows another embodiment in which the present invention is applied to a gas stove with a kiln, in which a smoke burner 61 and a smoke burner 6° are placed in the smoke exhaust passage 5 back and forth in the direction of smoke flow. The arrangement is different from the embodiment shown in Figs. 1 to 4 above, except that the upper and lower walls are arranged in a staggered manner so that the combustion surfaces of both smoke and combustion burners 616□ do not face each other. Not particularly different.

In the above two embodiments, the heat source for cooking is
When the lower burner 3.4 is burnt, a large amount of smoke is generated from the food to be cooked. However, 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 X to be cooked, etc., so the circuit shown in Figure 6 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 burns, 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, the upper and lower burners 3.4
When a lot of smoke is produced during firing, such as when burning burners 6 and 6 Since there is no interference, the flow of exhaust gas in the smoke exhaust passage 5 is not obstructed by the thermal pressure of both smoke combustion burners 61 and 62 even if the height of the smoke exhaust passage 5 is not increased. When the heat source for the burner is a burner as in this embodiment, the burner 61 for both smoking and burning
6□ burns well without flashback.

In the two embodiments described above, the upper burner 3 and the smoke burner 61 and the lower burner 4 and the smoke burner 6□ were each constructed as separate burners, but as shown in FIG. They may each be configured with an integrated burner. In this case, the upper burner 3 and the smoke burning burner 61 and the lower burner 4 and the smoke burning burner 62 are each integrated, so they work together.

In this example, a projecting piece 5a protrudes into the firing chamber 2a of burner B.
The part facing the smoke exhaust passage 5 formed by the smoke combustion burner 61 becomes the smoke combustion burner 61.

In addition, even when the heat source for the upper heat and the heat source for the lower heat are activated,
Depending on the type of food to be cooked, smoke may not be generated.
In such a case, all of the plurality of heat sources for burning smoke may be stopped. That is, by using a control circuit as shown in FIG. 8, the on-off valve 1 of the smoke burning burner 616
3.14, and according to this, both the smoke burner 6 and the smoke burner 6□ can be burned even when only the top burner 3 or the bottom burner 4 is burning. .

At this time, for example, the smoke burners 6 and 62 may be burned in response to all smoke signals from a smoke sensor provided near the entrance of the smoke exhaust passage 5 to burn and reduce the smoke.

Fig. 9 and Fig. 1O show still another embodiment. In this example, the heat source for cooking is only the lower burner 4, and the smoke burner 61.6□ is set according to the smoke generation port. It is possible to control the stoppage of both smoke burners 6, 6□, the combustion of one smoke burner, and the combustion of both smoke burners 6, 6□.

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 combusted without waste while the heat source for cooking always works well.
