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 stove 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 low-capacity, low-pressure ones for safety reasons, and because the fire is weak, even a slight breeze can blow it out, making it unsuitable for outdoor use.

In addition, the heat 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 and long cooking times, and high fuel consumption, making it unsatisfactory in terms of energy savings.

To solve the above-mentioned drawbacks of the conventional method, it is possible to install a separate windshield cover, etc., but this would increase the number of parts and complicate the structure. It could even lead to a loss.

The purpose of this invention is to provide a simple cooking stove that can solve the above-mentioned conventional drawbacks without increasing the number of parts or complicating the structure, and is convenient to carry and handle.

Describing the embodiment shown in FIGS. 1 to 5, reference numeral 1 denotes a stove body, and a cylinder storage chamber 3 is formed adjacent to one side of a cooking section 2.

The cooking section 2 has an upward opening 4 and the chamber 3.
A gas burner 6 is provided to which a gas cylinder 5 housed inside is connected.

A saucer 7 located around the burner 6 is provided on the upper surface of the cooking section 2, and the burner 6 is attached to the outer peripheral edge of the saucer 7.
A windshield wall 8 surrounding the heating space is integrally formed, and the saucer 7 is intended to also serve as a main body cover that covers the stove main body 1.

The windshield wall 8 is formed sufficiently higher than the top surface of the burner 6 in order to protect the flame from the burner 6 from being blown out by the wind.

The saucer 7 has a square plan view, has a burner outlet 9 in the center of the bottom, and has a ventilation hole 10 in the upper part of the windshield wall 8 rising from the outer periphery of the bottom.

On the other hand, the stove body 1 has a short shape in which the rear side of the cooking section 2 opposite to the side adjacent to the cylinder storage chamber 3 is closer to the burner 6 than the other three sides. It is formed into a square plane with approximately the same size as the saucer 7 so that the saucer 7 can be placed over it.

Therefore, when the saucer 7 is placed on the cooking section 2, a portion of the saucer 7 protrudes from the rear side of the cooking section 2 as shown in FIGS. 1 and 2, but when removed from the cooking section 2, It can be placed over the stove body 1 as shown in the imaginary line in FIG. 2 and in FIG. It is lightweight and has a block-like structure with no uneven surfaces, making it convenient to carry, stack, and store.

Shorter dimensions also reduce material costs.

The stove body 1 has an upper half 1a that is covered by the saucer 7, which is smaller than the lower half 1b by the thickness of the saucer 7, so that when the saucer 7 is covered, the upper opening edge 8a of the windshield wall 8 is smaller than the lower half 1b. It is seated on the stepped portion 1C between the upper and lower halves 1a and 1b, and the surfaces of the saucer 7 and the lower half 1b are substantially flush with each other.

When the saucer 7 is placed on the cooking part 2 of the stove body 1,
In order to eliminate instability caused by the protrusion of the saucer 7 from the cooking part 2, a rotating arm is pivoted by a vertical shaft 12 in a recess 11 formed on the left and right sides of the lower rear side of the cooking part 2 of the stove body 1. 13a, and a saucer holding leg 13 which also serves as a grip when carrying is integrally formed on each free end of the arm 13a, and when both the holding legs 13 are opened, the saucer is held as shown in FIGS. 1 and 2. When the protruding portion 7 is received and stabilized, and both holding legs 13 are closed as shown in FIG. 5, it becomes a handle grip when carrying the stove body 1.

Reference numeral 14 indicates a leg of the main body 1 itself, which is fixed to the lower surface of the stove main body 1.

The stove body 1 further includes a step part 15 formed between the cooking part 2 and the cylinder storage chamber 3, and a protection part provided in a part of the windshield wall 8 of the saucer 7 placed on the cooking part 2. Matching hole 1
A key-shaped engagement piece 17 that engages with the saucer 7 is provided to prevent the saucer 7 from rotating or falling off. saucer 7 placed on 1a
An engaging protrusion 19 a with which the clip fitting 18 that engages with the retaining hole 16 of the cylinder storage chamber 3 and the vent hole 10 of the saucer 7 placed on the side surface of the lid 19 of the cylinder storage chamber 3 and the upper half 1 a of the main body are elastically engaged. are formed, respectively, so that the saucer 7 can be fitted over the stove body 1 as shown by the imaginary lines in FIG.

Note that the recessed portion 11 serves as a restriction portion that restricts the proper movable range of the holding leg 13.

Reference numeral 20 is an adjustment knob that is used for both ignition and flame adjustment, 21 is a set knob for setting or releasing the gas supply state of the cylinder 5 into the cylinder storage chamber 3, and 22 is a finger rest for operating the knob 21. Each of the fixing pieces is provided in a recess 23 formed on the circumferential side of the stove body 1 to prevent it from getting caught when carried. It is hidden behind the saucer 7 that covers the body to prevent other objects from hitting the knob 20 and turning it when carried, and the stepped portion 20a of the knob 20 is inserted into the windshield wall edge 8a of the saucer 7 as shown in Fig. 4. It is designed so that it comes into contact and is prevented from rotating.

Reference numeral 24 is a resting trivet on which a cooking container or the like may be placed directly, or a perforated iron plate 25 or the like may be placed thereon.

Reference numeral 26 denotes a notch for storing a cylinder, which is formed by cutting out a suitable part of the flange 4a formed in the opening 4 of the cooking part 2.
It provides escape and positioning for storing the cylinder 5 inside as shown in the imaginary line in Figure 3. By storing a spare cylinder when carrying it, or by removing and storing the cylinder in the chamber 3, Even if the knob 20 should turn when the cylinder is being carried around with the cylinder set, it is possible to avoid a situation in which gas blows out.

In the embodiment shown in FIGS. 6 and 7, the upper surfaces of the cooking part 2 and the cylinder storage chamber 3 of the stove body 1 are made flush with each other, and the saucer 7 is placed on the entire stove body 1. The tray 7 is provided with a handle 30 for carrying.

In the embodiment shown in FIGS. 8 to 11, the cylinder storage chamber 3 and the cooking section 2 are connected at one end by a hinge 40 so as to be freely openable and closable. When the stove is closed and not in use as shown in Figure 8, it covers the entire stove body 1 as shown in the figure and also serves as a cover, and when the stove is in use, the storage chamber 3 and cooking section 2 are opened as shown in Figure 9. It is placed on the cooking section 2 in a flat state and used as a saucer.

The opening of the storage chamber 3 and cooking section 2 during this use is as follows:
Burner 6 for cylinder 5 stored in storage chamber 3
Safety is improved because heat effects from heat can be suppressed.

Note that the gas receiving path 41 of the burner 6 provided in the cooking section 2 and the gas supply path 42 from the gas cylinder 5 are connected by a rotatable connecting portion 43 that can rotate concentrically with the hinge 40, and 3 and the cooking section 2 are allowed to open and close.

Such an opening/closing connection structure is arbitrary, and as long as the structure is satisfactory in terms of strength, the hinge connection between the storage chamber 3 and the cooking section 2 can also be used.

In each of the embodiments described above, the windshield wall 8 of the saucer 7 surrounds the space heated by the burner 6, and not only prevents the flame from being blown out by the wind, but also prevents the heat from the burner 6 from dissipating to the surroundings. The heat efficiency is further improved if the inner surfaces of the saucer 7 and the windshield wall 8 are mirror-finished reflective surfaces.

According to this invention, a windshield wall that surrounds the space heated by the burner is formed on the outer periphery of the saucer provided around the gas burner in the cooking section of the main body of the stove, so that the flame is not blown out by the wind. In addition to being able to prevent heat from burning and allowing safe and reliable cooking even outdoors, it also prevents heat from the burner from dissipating into the surrounding area, improves thermal efficiency, and allows cooking to be completed successfully in a short amount of time.

In particular, the windshield wall can be integrally formed with the saucer without increasing the number of parts or complicating the structure.

Moreover, the saucer doubles as a cover that covers the stove body using its windshield wall, eliminating the need for a stove container such as a special case that is conventionally used when carrying, stacking, or storing the stove. It is easy to handle regardless of whether it is used or not.

Moreover, cost reduction can also be achieved.
