Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a novel cooking stove that uses a long combustion heating tube such as a radiant burner as a burner.

(Prior Art) Conventional stoves are equipped with a burner of red flame type, Bunsen type, all-primary air type, etc., and a trivet on which the object to be heated is placed above the burner, in the stove body.

(Problems to be Solved by the Invention) The conventional stove described above requires a separate trivet in addition to the burner, which has the disadvantage of increasing the number of parts.

(Means for solving the problem) The present invention attempts to solve the above-mentioned inconvenience by using a burner that can also be used as a trivet. Gas and combustion air are introduced into the long tube from one end, combustion occurs within the long tube to heat the surrounding area, and combustion exhaust is released from the other end of the long tube to the outside. The long tube is bent in the vertical direction so that one end side is upward, and the upper part thereof is formed as a mounting table for the object to be heated.

(Function) The present invention has the above-mentioned configuration. According to this, the object to be heated can be placed on the mounting table in the upper part of the long combustion heating tube, and in this state, the long combustion heating tube is combusted. , the object to be heated can be heated.

(Example) Next, an example of the present invention will be described based on the drawings.

1 and 2 show a first embodiment of the present invention, in which 1 indicates a stove body;
A long tube 3 is bent in a spiral shape with one end facing up on a support frame 2 consisting of two plate-like members crossed in the X shape above, and the outer part is located above the inner part. A long combustion heating tube 4 serving as a burner was placed, and a pot A serving as an object to be heated was placed on the upper part of the outside thereof.

The long combustion heating tube 4 is connected to the long tube 3 in a spiral shape from a mixing combustion chamber 7 having an air inlet 5 for blowing combustion air from a substantially tangential direction and a gas supply port 6 for supplying gas from an axial direction. A plurality of exhaust heat outlet ports 8 are provided in a portion near the other end of the long tube 3.

In this case, the combustion air flowing in a swirling flow and the gas flowing linearly through the center of the swirling flow move inside the spiral long tube 3 from one end to the other end. Since the mixture is gradually mixed, if an ignition device (not shown) is provided at an appropriate position near the gas supply port 6, the mixed gas can be combusted over a long area. The pot A placed on the upper part of the tube 3 can be heated directly. In this case, from the exhaust heat outlet 8 of the long pipe 3 to the pot A
High-temperature waste heat is blown out toward the pot, and the pot A can also be heated by this, so heating efficiency is improved.

3 and 4 show a second embodiment of the present invention. In this case, the burner is formed by bending a long tube 3 into a U-shape, with one half of the tube being bent and the other half being the other end. 2 of the elongated combustion heating tube 4, which is arranged diagonally above and has an exhaust heat outlet 8 in the other half of the end.
The pot A, which is an object to be heated, was placed on one half of the upper end of the long tubes 3, 3 of both the long combustion heating tubes 4,4 so as to straddle it.

FIG. 5 shows a third embodiment of the present invention, in which no exhaust heat outlet is provided near the other end of the long pipe 3.
This is not particularly different from the first embodiment except that the combustion exhaust discharged from the other end of the long tube 3 is directed toward the bottom of the pot A and used for heating.

FIG. 6 shows a fourth embodiment of the present invention.
This embodiment is not particularly different from the second embodiment except for the relative arrangement of the 32 long tubes bent into a character shape.

Note that the combustion operations in the second to fourth embodiments are not particularly different from the combustion operations in the first embodiment, and will therefore be omitted.

(Effects of the invention) As described above, according to the invention, the burner in the stove body is composed of at least one long combustion heating tube, and the long tube is bent in the vertical direction with one end facing upward. Since the burner itself serves as a trivet on which the heated object is placed, the burner itself has the effect of eliminating the need for a trivet.
