Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cooking device suitable for grilling grains and other foods that do not produce cooking juice.

[Prior Art] For cooking grilled foods, a gas burner, an electric heater, or the like is used as a heating source, and an oven using this heating source is used. Also, a grilled food cooking device has been proposed that is heated by this heating source and is equipped with a medium that radiates heat rays including far infrared rays.

[Problems to be Solved] However, conventional ovens have the disadvantage that they generate little far-infrared rays, heat only the surface of the food being baked, and have poor convection of hot air, resulting in steamed food. In addition, even in cooking devices that use heat radiation as a radiation medium, it is difficult to heat the object evenly from both the top and bottom, or even if possible, two heating sources such as burners are required on the top and bottom, and the convection of hot air is difficult. It was badly steamed and grilled.

The purpose of this invention is to provide a grilled food cooker that can heat the food almost evenly from both the top and bottom surfaces with far infrared rays using one burner.

[Means for Solving the Problems] In order to achieve the above object, the pottery cooker of this invention includes a case provided with a pottery entrance with a door, a burner disposed at the bottom of the case, and a burner located above the burner. a lower far-infrared radiator disposed in a planar manner; a heat shield provided between the burner and the lower far-infrared radiator; and a heat shield disposed in a planar manner above the lower far-infrared radiator. an upper far-infrared radiator, a shelf for arranging pottery in a plane between the lower far-infrared radiator and the upper far-infrared radiator, and a heat shield in the case. , lower far-infrared radiator, shelf,
and a hot air passage provided on the side of the upper far-infrared radiator and guiding hot air from the burner to the upper surface of the upper far-infrared radiator, and an exhaust port provided in the case below the upper far-infrared radiator. A configuration consisting of was adopted.

[Functions and Effects of the Invention] The present invention has the following functions and effects.In the case, far-infrared radiators are disposed in a planar manner on the top and bottom, and a shelf is provided between them on which food to be cooked is arranged in a planar manner. A burner placed at the bottom of the case heats the far-infrared radiator, and the far-infrared rays emitted from the far-infrared radiator heat the food from both the upper and lower surfaces. This allows far-infrared rays to be irradiated onto the food from both the top and bottom sides.

In addition, a heat shield is placed above the burner to prevent the lower far-infrared radiator from overheating, and a hot air passage is provided to directly guide the hot air from the burner to the upper far-infrared radiator. Since it is heated, the temperature of the upper and lower far-infrared radiators can be made uniform. This allows the food to be cooked to be heated almost evenly from both the top and bottom sides.

[Example] Figs. 1 and 2 show a commercial roasted sweet potato maker 100 according to a first embodiment of the roasted food cooker of this invention.

Reference numeral 1 denotes a metal box-shaped case, the front wall 11 is provided with a door 1a and an opening 1b for putting in and taking out potatoes, the lower part of the side wall is provided with an air suction hole 1c, and the upper part of the back wall 12 is provided with an air intake hole 1c. An exhaust hole 1d is provided.

2 is a gas banner attached to the lower part of the case 1.

Above the burner 2 is a lower far-infrared radiator 3.
are arranged in a plane. In this embodiment, the lower far-infrared radiator 3 is constructed by constructing a lower shelf 31 made of iron cage above the burner 2, and laying a large number of hole-shaped hollow ceramic charcoal balls 32 on the lower shelf. The ceramic charcoal 32 is made by applying a ceramic coating having a high characteristic of emitting far infrared rays similar to that of charcoal on the surface of a ceramic base material having a spherical hollow body with many holes.

A heat shield 4 is installed between the burner 2 and the lower far-infrared radiator 3. In this embodiment, the heat shield 4 has approximately the same area as the lower far-infrared radiator 3, and is constructed by constructing a perforated iron plate 42, in which a large number of small holes 41 are formed, over the burner 2. This heat shield 4 prevents the heat generated by the burner 2 from directly heating the lower far-infrared radiator 3, and allows it to be heated by the hot air passing through the small hole 41 and radiation from the heat shield 4. , suppresses excessive temperature rise of the lower far-infrared radiator 3.

Above the lower far-infrared ray radiator 3, an upper far-infrared ray radiator 5 is disposed in a planar manner. The upper far-infrared radiator 5 has an upper shelf 51 made of iron cage constructed above the lower far-infrared ray radiator 3.
A large number of small spherical ceramic charcoal 52 are laid in the charcoal. The ceramic charcoal 52 is made by applying a ceramic coating having a high characteristic of emitting far-infrared rays similar to that of charcoal on the surface of a ceramic base material having a solid spherical shape the size of a ping-pong ball.

The base material of ceramic charcoal 32 and 52 is mullite (3Al ₂ O ₃・2SiO ₂ ) + cordierite (2
MgO.2Al ₂ O _{3.5SiO 2} ) is used. The coating material includes 5 to 20% of mullite/cordierite, which is the composition of the above base material, and MnO ₂ 30%.
~70%, _{Fe2O35 ~} 30%, CoO5~20%, _ZrO20
-10% _TiO2 and 0-10% TiO2 is used.

Between the lower far-infrared ray emitter 3 and the upper far-infrared ray radiator 5, an iron cage shelf 6 on which pottery is arranged in a planar manner is installed so that it can be pulled out when the door 1a is opened. .

Both sides of the lower far-infrared radiator 3, the heat shield 4, the upper far-infrared radiator 5, and the iron cage shelf 6 are spaced apart from each other by a gap 13 on the inner wall of the case 1. The gap 13 serves as a hot air passage 7 that directly guides hot air from the burner 2 to the upper far-infrared radiator 5.

With this configuration, when the potatoes 10 are lined up on the shelf 6 and roasted, the burner 2 heats the lower far-infrared radiator 3 and the upper far-infrared radiator 5 equally, and the ceramic charcoal 32 and 52 emit almost the same amount of far infrared rays. This results in 10 potatoes
is heated evenly from both the upper and lower surfaces, and since the lower far-infrared radiator 3, heat shield 4, upper far-infrared radiator 5, and iron cage shelf 6 all have ventilation, hot air is distributed throughout the case. Go around.

As a result, the heat storage effect of ceramic charcoal, the effect of heat penetration into the interior by far infrared rays, and the drying effect of hot air overlap, and the potatoes 10 are properly cooked to the inside and baked without losing flavor.

3 and 4 show a commercial sweet potato roasting machine 200 according to a second embodiment of the present invention.

In this sweet potato pot 200, the case 1 includes the top plate 14.
A door 1A is provided, and the upper far-infrared radiator 5 is fixed to the lower surface of the door 1A, so that when the door 1A is opened, the potatoes can be seen. This allows you to sell products while showing them.

Further, a large number of small spherical ceramic charcoals 52 are laid in the lower far-infrared radiator 3, and the heat shield 4 includes a bottom plate that insulates the lower surface of the lower far-infrared ray radiator 3 without holes, and a lower far-infrared ray radiator 3. It consists of a radiator 3 and a frame plate surrounding an iron cage shelf 6.

[Modification] In the above embodiment, spherical ceramic charcoal is used as the far-infrared radiator, but the shape of the ceramic charcoal may be columnar or plate-shaped.
