Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cooker, and more particularly to a cooker that heats food by a heater.

[0002]

[Prior Art]

 A conventional cooker of this type will be described with reference to FIG. Reference numeral 20 in the drawing denotes a cooking chamber, and an upper heater 21 and a lower heater 22 are arranged in the cooking chamber 20. A cooktop 28 is disposed above the lower heater 22, and a reflector 23 is disposed above the upper heater 21 so that the radiant heat of the upper heater 21 is applied to the entire cooking chamber 20. ing. A top surface portion 27 is disposed further above the reflection plate 23, and an exhaust port 24 for exhausting smoke and odor generated in the cooking chamber 20 to the outside is disposed at an end portion of the top surface portion 27. ing. An oxidation catalyst 26 is internally fixed to the exhaust port 24, and the exhaust gas from the cooking chamber 20 always passes through the oxidation catalyst 26 to reduce smoke and deodorize before being discharged.

When cooking in the cooking device configured as described above, the food placed on the food placing table 28 is directly heated by the upper heater 21 and the lower heater 22, and is placed above the upper heater 21. It is heated and cooked by the indirect heating by the reflected heat of the reflected plate 23. Smoke and odor generated by heating the cooking product are exhausted to the outside through the exhaust port 24 at the end of the top 27. At this time, when the smoke and odor components that have been heated by the upper and lower heaters 21 and 22 and have a high temperature pass through the oxidation catalyst 26 filled in the exhaust port 24, they are processed by the oxidation catalyst 26 to reduce smoke and odor. It is converted and released outside the device. Known examples of techniques for reducing smoke and deodorizing using the oxidation catalyst 26 are JP-A-61-87512, JP-A-62-127022, and JP-A-59-71723. It is disclosed in JP-A-61-176316 and JP-A-63-127724.

[Problems to be solved by the device]

 However, in the cooking device as described above, when smoke and odor during cooking are reduced, especially when the cooked food is heated from the front and back sides, the meat juice and the like discharged from the cooked food drips onto the lower heater 22. , Smoke and odor may increase. The smoke and odor generated at this time are limited in processing by the oxidation catalyst 26 internally fixed to the exhaust port 24, and there is a problem that the smoke and odor are released to the outside without being fully smoked and deodorized.

Further, since the cooked food is directly heated by the tubular upper and lower heaters 21 and 22, and further indirectly heated by the reflection plate 23, there is a problem that uneven baking occurs on the surface of the cooked food. It was The present invention has been devised in view of the above problems, and can reduce smoke and odor generated from cooked foods, and evenly heat the cooked foods surface to prevent uneven baking. The purpose is to provide a cooker.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the cooking device according to the present invention is provided with a ceramic heater formed in a honeycomb shape or a corrugated shape over at least substantially the entire upper surface of the cooking chamber, and the surface of the ceramic heater is oxidized. The feature is that the catalyst is retained.

[0007]

[Action]

 According to the above configuration, the ceramic heater formed in a honeycomb shape or a corrugated shape is arranged at least over substantially the entire upper surface of the cooking chamber, and the oxidation catalyst is held on the surface of the ceramic heater. The heat spreads evenly over the entire surface of the cooked product, eliminating uneven baking. Further, since the oxidation catalyst is held in the heater, the catalyst treatment at high temperature and the catalyst treatment in a large area can be performed, and the smoke reduction and deodorization effect is improved.

[0008]

Embodiment An embodiment of the cooking device according to the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view schematically showing a cooking device according to this embodiment. In FIG. 1, reference numeral 10 denotes a cooking chamber, and an upper heater 11 and a lower heater 12 are arranged in the cooking chamber 10. The cooking table 18 is provided above the lower heater 12. The upper heater 11 is made of ceramic, is formed in a honeycomb shape, and covers the entire upper surface of the cooking chamber 10 so that the entire cooking object placed on the cooking object placing table 18 can be uniformly irradiated. It is arranged. Further, an oxidation catalyst (not shown) such as platinum is held on the surface of the upper heater 11. A top surface portion 13 is disposed above the upper heater 11, and smoke and deodorized smoke generated by the oxidation catalyst generated in the cooking chamber 10 at the end of the top surface portion 17 and held by the upper heater 11 An exhaust port 15 is provided for discharging the odor to the outside.

When cooking with the cooker configured as described above, the food placed on the food placing table 18 is heated by direct heating by the upper heater 11 and the lower heater 12 to be cooked. Smoke and odor generated by heating the cooking product are exhausted to the outside through the exhaust port 24 at the end of the top 27. At this time, the oxidation catalyst held by the upper heater 21 is kept at a high temperature according to the temperature of the upper heater 11 itself, the operation by this oxidation catalyst is promoted, and smoke and odor components pass through the exhaust port 24. When it is used, smoke and odor are sufficiently reduced and released to the outside.

As described above, since the upper heater 11 is provided on substantially the entire upper surface of the cooking chamber 10, it is possible to cook the cooked product without causing uneven baking, and moreover, the lower heater 12 from the cooked product. Even when the meat juice drips on the surface and the smoke and odor increase, the oxidation catalyst is retained on the surface of the upper heater 11, so that the oxidation catalyst is kept at a high temperature and the catalytic action by the oxidation catalyst is promoted. As a result, the smoke reduction and deodorization effect can be improved.

Although the above embodiment shows the case where the upper heater 11 is formed in a honeycomb shape, the upper heater 11 is not limited to a honeycomb shape, and in another embodiment, it is formed in a corrugated shape. May be done. By forming the upper heater 11 in a honeycomb shape or a corrugated shape in this manner, the oxidation catalyst can be held in a larger amount in the upper heater 11, and thus the smoke reduction and deodorization effect can be enhanced.

[0013]

[Effect of the device]

 As described in detail above, in the cooker according to the present invention, the honeycomb-shaped or corrugated-shaped ceramic heater is provided at least over substantially the entire upper surface of the cooking chamber, and the surface of the ceramic heater is Since the oxidation catalyst is held by the heater, the heat of the heater is evenly distributed over the entire surface of the cooked product, so that uneven baking can be prevented. Further, since the oxidation catalyst is held in the heater, the oxidation catalyst is kept at a high temperature, the catalytic action of the oxidation catalyst is promoted, and at the same time, the catalytic treatment is performed in a large area. Therefore, it is possible to improve the purification effect of smoke and odor generated during cooking.
