Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pottery which cooks yakitori or the like by charcoal fire.

[0002]

2. Description of the Related Art In a pottery that heats and cooks using charcoal, a charcoal stove is housed in a housing, or charcoal is put directly into the housing so that a grill, iron plate, etc. It is used by placing a cooking plate.

When cooking a yakitori or the like, heat is generated, and the housing becomes hot due to the heat, and there is a risk of touching the hot housing and causing burns. In addition, the heat released during cooking has caused discomfort to those around the user. Especially, in the case of a pottery for business use, since the housing is made of metal, the above-mentioned problem becomes prominent.

Therefore, the technical means of making the wall of the pottery ware hollow and flowing cooling water or chlorofluorocarbon as a cooling medium therethrough,
It is disclosed in Japanese Utility Model Registration No. 3014038.

[0005]

However, if cooling water is used as the cooling medium, the heat generated by cooking can be cut off, but a large amount of water is required, and the supply source and discharge destination of the cooling water must be secured. Therefore, the installation place of the pottery will be limited. Also, CFCs can also block heat in the same way, but they have the drawback that they are not environmentally friendly.

[0006] It is an object of the present invention to provide a porcelain burner which cuts off heat generated by a charcoal fire without using water or a refrigerant.

[0007]

In order to solve the above-mentioned problems, according to the present invention, a cooling passage for flowing cooling air is formed between an outer wall of a casing and a heating chamber, and the cooling passage is formed in the casing. A fan for sucking outside air from the intake port to the cooling passage is provided.

Therefore, by forcibly sucking the outside air from the intake port with the fan, the air flows into the cooling passage, heat conduction to the outer wall of the housing can be prevented, and a heat shielding effect can be obtained. Further, if the air supply path is formed so as to guide the air sucked from the intake port to the charcoal stove in the heating chamber, the combustion air can be supplied to the charcoal and the charcoal can be quickly aerated.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 is a diagram showing the internal structure of the pottery ware of this embodiment, FIG. 2 is a plan view thereof, FIG. 3 is a front view thereof, FIG. 4 is a left side view thereof, and FIG. 5 is a right side view thereof. is there.

In the present pottery, a heating chamber 3 for accommodating a charcoal stove 2 is formed inside a housing 1, and a grill 4 for placing an object to be cooked is arranged above the heating chamber 3. . The case 1 is
It consists of a metal box with an open top.

The heating chamber 3 is formed by an inner box 5 having an open upper surface, and the inner box 5 is mounted in the housing 1. The charcoal stove 2 is arranged in the inner box 5, and its upper edge is detachably supported on the upper surface of the inner box 5. Charcoal stove 2
A charcoal sludge 6 is placed on the bottom surface of the.

An ashtray 7 is provided on the bottom surface of the inner box 5 and is slidable with respect to the bottom surface of the inner box 5 so as to be detachable from the front surface of the housing 1. Between the charcoal stove 2 and the ashtray 7,
A burner 8 for charcoal ignition is arranged. The grill 4 arranged above the charcoal stove 2 is detachably mounted on the upper surface of the housing 1.

A cooling passage 9 for flowing cooling air is formed between the outer wall of the casing 1 and the heating chamber 3, and an intake port 10 communicating with the cooling passage 9 is formed on the upper surface of the casing 1. A fan 11, which is a suction device for sucking outside air from the intake port 10, is provided. The cooling path 9 is a space surrounded by the front wall 12 or the rear wall 13 and the inner box 5, and further surrounded by the bottom surface of the inner box 5 and the bottom plate of the housing 1.

The upper surface of the casing 1 on the front side and the rear side of the grill 4 is inclined, and an intake port 10 is formed therein. The intake port 10 is formed by cutting and raising a part of the inclined surface inward.
This makes it possible to catch the sagging of the yakitori and the like and prevent it from entering the cooling passage 9.

In the cooling path 9, below the inner box 5,
Two fans 11 are arranged. An exhaust port is formed on the bottom plate of the housing 1. The fan 11 is driven by turning on / off the fan power switch 15. The external air sucked from the intake port 10 by driving the fan 11 passes through the cooling passage 9 and is discharged from the exhaust port.

Further, the sucked air is used to set fire for charcoal. Therefore, the air supply passage 16 that communicates from the cooling passage 9 to the inside of the inner box 5 is formed, and the air sucked by the fan 11 is directly supplied into the heating chamber 3 through the air supply passage 16. In the figure, reference numeral 17 is a fire raising air volume adjusting plate, and 18 is a bar.
It is a knob for na.

When the above-mentioned pottery is used, charcoal is ignited by the burner 8 and a cooked item such as a yakitori is placed on the grill 4 arranged on the upper surface of the housing 1 and cooked. . Due to the conduction of heat generated at this time, the outer wall of the housing 1 becomes hot. Therefore, by forcibly sucking air from the intake port 10 using the fan 11 and flowing the air to the cooling path 9,
It is possible to prevent heat conduction from the heating chamber 3 to the outer wall of the housing 1 and prevent the outer wall of the housing 1 from reaching a high temperature. Also,
The exhaust gas of the fan 11 can be passed through the air supply passage 16 and sent into the heating chamber 3 to be used for the ignition of charcoal.

A large amount of smoke and odor are generated when cooking a yakitori or the like, but when the fan 11 inhales the air, they are also inhaled, so the smoke directly applied to the face or the like of the surrounding people. And the smell can be reduced.

The present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention. For example, although charcoal is used as the combustor in the above embodiment, it may be combusted using a combustion gas, an electric heating coil, or the like. A duct may be used as the suction device and suction may be performed by an external fan.

Further, as shown in FIG. 6, the cooling passage 9 may be folded back so as to have a double structure, and the intake port 19 is formed below the outer cooling passage 9 so that the fan 11 is forced from the lower portion of the housing 1. Inhale air into. Since the wall of the housing 1 is doubled, the air layer becomes two layers, and since the air having a lower temperature than the upper portion of the housing 1 is sucked in, the efficiency of blocking heat conduction from a charcoal fire is increased. be able to.

[0021]

As is apparent from the above description, according to the present invention, forced air convection is used to cause cooling air to flow around the heating chamber in the housing, so that heat from the heating chamber to the outside can be reduced. Conduction can be blocked. Therefore, the outer wall of the housing can be prevented from being heated to a high temperature, and even if it touches it, it is not burned and the safety is improved. Moreover, since heat radiation from the side wall of the housing is reduced, it does not bother other people.

Further, since the cooling medium is air, it is not necessary to prepare a large amount such as water and the like, and the environment such as CFC is less harmful, and the water supply / drainage facility is not required. Can be easily installed without. Furthermore, since the exhaust air of the fan is used to set fire to charcoal,
Since it does not take time to send air for a new fire, it also leads to cost reduction.
