Description

  The present invention relates to a combustion appliance that can be used as a heating appliance, a heating cooking appliance, or a disaster prevention article.

  A conventional combustion instrument is composed of a combustion cylinder, a spark opening provided on the lower side (near the bottom) of the combustion cylinder, a rooster provided in the spark opening, and five virtues provided in the combustion cylinder. Fuel such as timber and wood waste such as thinned wood will be put into this outlet. The combustion air is introduced from the lower side of the peripheral part of the combustion cylinder. Therefore, it is difficult to introduce the air into the entire combustion cylinder through the gap of the opening, and there are problems such as poor combustion efficiency.

  An open gazette regarding this type of combustion appliance is, for example, a “portable range” described in Japanese Patent Laid-Open No. 8-173328 (referred to as Document (1)). The present invention is a structure including a stand, a firearm, an inner lid, a cooking container, and an upper lid in a cylindrical can body having an air intake port on the lower side of the peripheral portion, and is a structure for adding fuel to the firearm. Although this invention is simple, it is a miniaturization of the conventional structure, and as in the conventional case, air is not sufficiently taken into the throat and the combustion section, so that efficient combustion and insufficient thermal power Conceivable. Moreover, there exists a "combustion instrument" of Unexamined-Japanese-Patent No. 2015-87083 as a structure similar to literature (1) (it is set as literature (2)). The present invention includes an annular outer cylinder having an air intake opening, a bending pipe provided on the outer cylinder from the lower side of the peripheral portion toward the inner opening side of the outer cylinder, and a rooster provided on the lower side of the bending pipe, The structure is such that the lower side of the bending pipe provided with this rooster is the opening. Therefore, it is thought that it is the same structure as literature (1). That is, as in the conventional case, air is not sufficiently taken into the opening and the combustion part, and it is considered that the combustion is efficient and the thermal power is insufficient.

  Moreover, the internal combustion charcoal device is disclosed as another combustion appliance. For example, “Momigara-kun charcoal” described in JP2013-185019A (referred to as Document (3)). The present invention is for a chimney-cum-burning-out cylinder (Momigara-kun charcoal) having a notch and a pore-shaped air suction part in the lower part (foot), and a rice husk (Momigara-kun charcoal) The outer cylinder (bath boat), or a rice husk pile portion in which the cylinder body is embedded, and combustion auxiliary materials such as combustion wood or charcoal are put into the cylinder body. The rice husk is charcoalized from the bottom by radiant heat from the cylinder. 4 and 5, it is considered that the structure of the combustion device is composed of a bathtub (outer cylinder) and a cylinder (inner cylinder), but as in the literature (1) and the like, The intake of air into the combustion section is not sufficient, and it can be considered that the combustion is efficient and the thermal power is insufficient. In addition, this structure cannot be used for heating and cooking.

The air-fuel mixture rises from the vicinity of the lower portion 6a of the middle cylinder 6 due to the chimney effect, and burns near the middle portion 6b of the middle cylinder 6 in a high temperature state, generating flames and combustion gases (secondary combustion). The flame and the combustion gas further rise, and the flame reaches the inside 602 of the middle cylinder 6 (gap with the bag) → the opening 603 of the middle cylinder 6 → the five virtues 8 or the net body 10. In FIGS. 8A and 8B, the combustion gas (primary combustion) generated by carbonization of the rice husk 23 is sucked into the inside of the middle cylinder 6 through the air hole 601, and the lower portion 6a of the middle cylinder 6 From the vicinity, it rises by the chimney effect and burns in the vicinity of the middle portion 6b of the middle cylinder 6 in a high temperature state to generate flames and combustion gases (secondary combustion). The subsequent processes are based on the example of FIGS. 7-1 and 7-2.
