Description

[Detailed Description of the Invention] This invention relates to a so-called simple cooking stove that uses a small-capacity gas cylinder as a fuel source in a detachable manner and does not require a hose connection to the fuel source.

Since this type of simple controller does not require the hose connection, it should be possible to carry it freely and use it anywhere, whether indoors or outdoors.

However, the gas cylinders used are limited to small-capacity, low-pressure ones for safety reasons, and because the fire is weak,
Even the slightest breeze can blow it away, making it unsuitable for outdoor use.

In addition, the heating power is weak and the ratio of heat radiated to the surroundings to the effective heat effective for cooking is high, resulting in poor thermal efficiency, prolonging cooking time, and high fuel consumption, making it unsatisfactory in terms of energy savings.

To solve the above-mentioned drawbacks, it may be possible to install a separate windshield cover, but this would increase the number of parts and complicate the structure, and would impair the ease of portability, which is the original feature of a simple stove. It could even lead to this.

This invention is a simple stove that can solve the above-mentioned disadvantages without increasing the number of parts, complicating the structure, or making it inconvenient to carry, and making it effective and convenient for other types of cooking such as indirect cooking. In order to provide this, the cooking part of the stove body case in which the gas burner is installed is formed into a recessed cooking part with the gas burner combustion part protruding from the bottom, and the combustion part of the gas burner is formed in the recessed cooking part. A receiving bottom is provided, and the receiving bottom is removably seated on a seating part formed on the inner surface of the peripheral wall of the recessed cooking part.

Due to this configuration, the recessed cooking section allows the peripheral wall to serve as a windshield wall for the gas burner combustion section located at a lower level,
It traps combustion heat and prevents it from dissipating to the surrounding area.

At the same time, a cooking and storage space such as a heating medium storage section for indirect heating, an oven-type cooking chamber, or a storage chamber for accessories such as trivets is provided, separated from the gas burner installation section by a receiving bed.

Describing the embodiment shown in FIGS. 1 to 3, reference numeral 1 denotes a stove body case, and a cylinder storage chamber 3 is formed adjacent to one side of a cooking section 2. As shown in FIG.

The cooking section 2 is formed in a recessed cooking section in which a gas burner 5 combustion section that receives gas from a gas cylinder 4 housed in a cylinder storage chamber 3 projects from below at the bottom. A receiving bed 6 having a burner outlet 8 through which a combustion part 5 emerges is provided.

The recessed cooking part 2 is located on the gas burner installation part peripheral wall 1 of the case 1.
It is formed by a cooking section peripheral wall 7 extending above a, one side of the peripheral wall 1a is provided at the partition between the cooking section 2 and the cylinder storage chamber 3, and the other three sides form the outer surface of the stove body.

The cooking section peripheral wall 7 is formed to have a height sufficient to prevent the flame from the burner 5 from being blown out by wind.
It has a bent peripheral wall 7a that is bent inwardly and downwardly from the upper end opening edge 7a, and a tray seating stepped portion 1b into which the receiving bed 6 is fitted and received is fitted into the lower end opening of the bent peripheral wall 7a. At the same time, a ventilation hole 9 is bored at a lower position of the bent peripheral wall 7b.

10 is an opening/closing lid of the cylinder storage chamber 3, 11 is a trivet fixed to the saucer 6, 12 is an adjustment knob for both ignition and flame adjustment, 13
14 is a set knob for setting or releasing the gas cylinder 4 stored in the cylinder storage chamber 3 into a gas supply state, and 14 is a leg fixed to the lower surface of the stove body case 1.

The cooking section peripheral wall 7 surrounds the space heated by the burner 5 in the cooking section 2, and when the stove is used outdoors, it prevents the flame from blowing from the burner 5 even when the wind is blowing, and prevents the flame from blowing. There will be no such thing as being erased.

Further, the heat from the burner 5 is also prevented from dissipating laterally, and the effective heat for cooking is increased, so the thermal efficiency is improved.

The concave cooking section 2 can also be used to spread a heating medium such as gravel up to the top of the burner, and indirectly grill the desired food such as potatoes or fish thereon, or to heat it directly or indirectly in the concave cooking section. Various cooking methods can be used, such as cooking in a simple oven with an appropriate lid.

Since the cooking part peripheral wall 7 is integrally formed with the burner installation part peripheral wall 1a of the case 1, the number of parts does not increase or the structure becomes complicated, and it is convenient to carry.

Furthermore, the gas burner 5 is the shortest one with no unnecessary lower space, and the required installation height of the receiving bed 6 is set small.The top surface of the waist cooking part peripheral wall 7 is set to the minimum required height in the cylinder storage room. 3 It is flush with the top surface, so the overall size of the stove can be kept to the same level as conventional stoves, and it has the feature of being able to stably stack a large number of stoves.

In addition, when stacking, if the upper end of the trivet 11 protrudes upward from the top surface of the stove as shown in the figure, at least the protrusion of the upper end of the trivet should fit into the lower surface of the stove body case 1. As long as an opening is provided, there will be no problem.

In addition, since the receiving bed 6 is fitted deeply into the recess formed by the surrounding wall 7 of the cooking section, it is stable and does not easily fall off, and the trivet 11 can be made to not protrude or protrude too much toward the top of the stove, so that it does not get caught during use. It is safe to use because it does not cause any damage.

If the adjustment knob 12 and the set knob 13 are provided in the recess of the stove body case 1 to eliminate any protruding parts, it is convenient to store the stove in a portable case or the like and carry it around.

Reference numeral 15 denotes a ventilation hole bored in the stove main body case 1 and the opening/closing lid 10, and is for preventing the cylinder 4 in the cylinder storage chamber 3 from being overheated by the heat from the burner 5.
The vent hole 9 in the cooking part peripheral wall 7 is for supplying secondary air for the combustion of gas in the burner 5, and is used to supply secondary air to the burner 5 in the lower burner installation part of the cooking part 2 in the case 1. Since the ventilation hole 9 does not open directly to the outer periphery of the stove, no wind blows in, preventing the flame from being blown out even if it is formed large. There is no problem with the action.

In the embodiment shown in FIG. 4, the cooking section circumferential wall 7 is not provided with a bent circumferential wall as in the previous embodiment, and the boundary between the cooking section circumferential wall 7 and the burner installation section circumferential wall 1a to which the circumferential wall 7 extends is provided. A seating stepped portion 1b of the receiving bed 6 is formed on the top surface of the outer circumferential upwardly protruding strip 6a of the receiving bed 6.

This embodiment has the advantage that the structure is simplified since the bent peripheral wall is not provided, and the same effects can be achieved.

The windshield wall 7 may be formed in any form on the wall where the burner is installed, as long as it prevents the flame from being blown out by the wind, and may be formed on the inner periphery of the surrounding wall of the cooking section or its bent surrounding wall. If the surface facing the space heated by the burner is a mirror-finished reflective surface, the thermal efficiency will be further improved.

According to this idea, the concave cooking part formed in the stove body case makes the surrounding wall serve as a windshield for the gas burner combustion part located at a lower level, trapping combustion heat and suppressing its dissipation to the surroundings. Therefore, the flame will not be extinguished by the wind, and the effective heat efficiency for cooking will be increased, making weak firepower more effective, ensuring stable cooking even outdoors.

In addition, the recessed cooking section allows the heating medium storage section for indirect heating, the cooking space, or the open cooking space to be isolated from the burner installation section by the receiving floor, making it convenient for successfully performing various types of cooking. Therefore, various uses do not cause any adverse effects such as staining on the burner installation part and various incidental parts around it.

The recessed cooking part can also be used to store accessories such as trivets, etc., and the fact that they can be prevented from protruding is also convenient for handling and storage.

The tray is removable and convenient for cleaning after cooking.
