Description

DETAILED DESCRIPTION OF THE INVENTION The object of the present invention is to enable energy saving by complete combustion, environmental protection without accident, and delicious cooking, and to eliminate the drawbacks of conventional devices.

[Structure of Invention]

As shown in the attached drawing, the peripheral edge of the burner head 2 of the burner 1 for fluid fuel combustion is maintained at a constant interval, and a constant interval is provided on the outer periphery of the reticulated porous flame shield cylinder 8 coated with ceramic or the like made of a good heat conductor. A heat insulating tube 3 made of a heat insulating material is provided to surround and stand upright, and a porous heat transfer plate 4 made of a good thermal conductor coated with an infrared emitting substance such as ceramic is used as a packing 6 with the inner edge of the circular opening of the top plate 7 as a guide. An infrared radiant combustion apparatus capable of burning fluid fuel in a semi-hermetically-sealed housing which is fitted so as to cover the upper opening of the heat insulating cylinder (3) via a lid.

Since the present invention has a simple structure as described above, it can be electronically connected and can be fitted and connected to various safety devices, etc., and it can further improve added value, and its handling is no different from electrical products. In addition, since it is possible to expect further improvement in performance by using a plurality of flame shields, it is possible to provide an infrared radiant combustion device which can be applied in a wide field such as industrial fields.

[Action]

 The operation of the present invention will be described.

The flame generated by igniting the burner head 2 becomes a combustion flame (not shown), and also circulates and burns in the space inside the heat insulating cylinder 3 centering on the combustion chamber 12 to completely burn carbon monoxide into carbon dioxide, The combustion flame heats the infrared emitting material such as ceramics and the heat conductive material, absorbs the heat and emits it again. Radiant heat generated by this repeated operation is radiated to produce an efficient infrared ray.However, the combustion flame ejected from the burner head 2 collides with the inner surface of the heat transfer plate 4 and at the same time a part of the small hole 5 Interval 11 through hot gas
Flow into the combustion chamber 12 and repeat circulating combustion, whereby the fluid fuel is completely combusted and unnecessary carbon dioxide and the like are concentratedly discharged to the outside of the casing of the combustor, and infrared rays are emitted for a certain period even after the combustion is stopped. The exhaust temperature is extremely lowered by this circulating combustion.

〔Example〕

The present invention is the first of the present invention since there is currently no combustion apparatus that burns fluid fuel and radiates infrared rays with a gas table housing (the whole body not shown) being substantially sealed.

There are three types of energy used as means for cooking: conduction heat transfer, convection heat transfer, and radiant heat radiation, and most gas tables that use fluid fuel are of the conduction heat transfer type.
The current situation is that only some of them use the convection heat transfer type.

Further, the electromagnetic cooker uses radiant heat of an overcurrent, but it is a microwave rather than an infrared ray, so the infrared ray is rarely used.

A feature of the present invention is that the flame becomes a combustion flame in the combustion chamber 12, and while repeating cyclic combustion, the flame shield cylinder 8 coated with an infrared radiating substance such as ceramic, the heat transfer plate 4, etc. are heated to a constant temperature at the same time. The combustion can be stopped and the substance to be heated can be cooked only by the radiant energy of infrared rays. This is because when the infrared rays emitted from infrared radiation radiant heat such as ceramics are absorbed without passing through the heated material, the heated material itself undergoes molecular vibration and is self-heated.
Therefore, the food to be cooked is delicious and has a similar appearance to that cooked by conventional cooking equipment.

When the potatoes etc. of the substance to be heated are intentionally cooked immaturely in the test prototype based on the present application, the cross-section of the substance to be heated is immature on average, whereas the substance to be heated cooked by the conventional method is The outside is mature and the center is immature.

For example, when cooking rice, put the polished rice and an appropriate amount of water in a Pyrex container on the heat transfer plate 4 and ignite the burner head 2 for 6 minutes ~
A small vibration wave will form on the surface of the water in 7 minutes, at which point the gas combustion will be stopped and left for about 15 minutes, the rice will be completely cooked automatically.

You can also boil eggs and vegetables without using any water. Further, when the fish is grilled, smoke is generated instantaneously when it is baked with an ordinary heat conduction type gas stove, but when it was baked with the test prototype of the present invention, no smoke was emitted and it was baked.

In short, there are four methods of cooking: boiling, baking, steaming, and cooking, but the cooking according to the present invention is a special method that does not correspond to the above four methods and is positioned as low-temperature cooking, but it is an exception that cannot be cooked. Not all cooking is possible.

It should be noted that this device is similar to an electromagnetic cooker because it is not necessary to adjust the heating power after ignition of the burner head 2 and only the combustion time is adjusted by the object to be heated.

In addition, the temperature on the heat transfer plate during burning and radiation is 380 ℃ on average, and no red heat or discoloration occurs.

〔The invention's effect〕

Since the present invention uses infrared radiant heating, there is little heat loss and energy saving, and there is no incomplete combustion, etc. due to circulating combustion, so there is no emission of carbon monoxide, it is perfect for the environment, and the structure is extremely simple. Therefore, it is suitable for mass production and its economic effect is great.
