Description

The present invention relates to a tabletop cooker that uses a carbon solid fuel such as charcoal. More specifically, it relates to a charcoal fire tabletop cooker equipped with a white charcoal/black charcoal ignition device.

Japanese Patent Laid-Open Publication No. 2005-147524 "Tabletop Stove"

An object of the present invention is to restore the use of solid fuel such as charcoal, which has been generally used in the past, as a fuel for tabletop cooking utensils.
Japanese Patent Laid-Open No. 2005-147524 “Tabletop Stove” of Patent Document 1 discloses a tabletop stove for an inn, a restaurant, etc. that uses a charcoal fire, and is intended to enable grilling and hot pot dishes for two people. However, by coating the bottom surface and the side surface with an ash layer, the temperature of the bottom surface of the container can be kept low and it can be used as a tabletop cooking utensil. That is, only the upper surface of the combustion section for burning charcoal or the like is opened, so that the temperature rise of the bottom surface of the container is prevented and the container can be placed on the table. Since it is a conventional type of stove or brazier for local heating mainly for hand burning, there is a problem that cooking is limited because the burning action of the burning part is insufficient and the heating ability is low.

Problems to be solved by the invention

The present invention, by applying the combustion structure of the brazier/seven wheel type stove to the supply of the combustion air to the combustion unit, enhances the combustion action and enables pot cooking, grill cooking, etc. for a plurality of people. An object of the present invention is to maintain the temperature of the bottom surface of the stove at a low temperature, as in the case of the brazier type desk stove of the "desk stove" of Patent Document 1.
Furthermore, regarding the ignition of white charcoal, it is widely used as a means of raising white charcoal for household stoves and braziers by using an ignition material that mixes waste paper such as newspaper and wood chips, and using seven wheels. Has been done. However, in a recent residential environment, since the airtightness is high and the ventilation is poor, it is not appropriate to start a fire in the room, and there is a problem that the smoke detector and the fire alarm in the room are activated.
Also, there are those that use molded solid carbon charcoal added with an ignition agent as an ignition unit, but due to the generation of toxic gas, the use is limited to outdoor use, and is mainly used for outdoor barbecue cooking, It is inappropriate to start a fire in a room.
Therefore, the present invention enables the ignition of solid fuels such as white charcoal and black charcoal indoors only in an environment where smoke detectors, CO detectors, ventilation equipment, etc. are present as the white charcoal ignition device. This is an issue.
Another object is to provide a multifunctional charcoal stove that can be used as an emergency tabletop cooker in the event of a disaster.

As the ignition material mb, it is preferable to use a planed cutting piece of cypress wood, a dried piece of wild grass "for example, dry scent", or the like that produces "smoke" or "smell" upon ignition by match ignition.

Although cypress wood strips were used as the burn-up element mc, it is conceivable to apply cut wood strips, dried trees and wild fruits. It is necessary to produce solid carbide instead of ash by combustion and to ignite the charcoal for ignition.

Further, as the ignition material mc, similar to the ignition material mb, a planed cutting piece of cypress wood, a dried piece of wild grass "for example, dried smoky", and solid ignition agents such as candles, oils and paraffins are used as a match. It is also possible to use an ignition device that quickly and surely ignites the tubular body 10A, but at least an ignition device that emits "smoke" and "smell" is preferable.
