Abstract

PURPOSE:To prevent a shadow from being generated at a red heat part of an outer flame cylinder above a cutout, prevent a deterioration of characteristics of exhaust gas and improve an outer appearance of a unit by a method wherein a control plate is arranged above the recess formed inside of the outer cylinder. CONSTITUTION:When a wick 1 is ignited, air required for performing combustion is flowed through an inner flame cylinder 2, each of air holes 2a and 3a of an outer flame cylinder 3 and a through-pass hole 3b of a red heat part 3c under passing of hot combustion gas through a combustion chamber 4, a part of air and a heat of the flame to keep the flame in each of the air holes are supplied to the wick 1, the liquid fuel is evaporated and the combustion is continued. At this time, since the air flowing from the cutout 8a for the igniter device 10 is restricted by the control plate 11 arranged inside of the outer cylinder 8, an amount of combustion is reduced at the air hole 3a below the outer flame cylinder 3, a combustion position is lifted, the flame is kept stable even at the front side of the red heat part 3c, a cold light-dark shadow can be prevented, an occurrence of carbon monoxide is reduced and a preferable condition of the outer appearance may also be kept.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a combustion device used for home heating and the like.

2. Description of the Related Art A conventional combustion device of this type has an outer cylinder A as shown in FIG.
: It was constructed so that a notch B for ignition was provided on the front side. C) is an outer cylinder handle.

Problem 511 to be Solved by the Invention However, in the above configuration, a larger amount of air is sucked from the cutout [F]) than from the lower part of the other outer cylinder A, and the lower air of the outer flame cylinder is The amount of combustion in the holes increases, the amount of combustion in the immature part decreases, the red-hot temperature at the front of the red-hot part decreases, - carbon oxide is generated, deteriorating the exhaust gas characteristics, and a dark shadow appears in front of the red-hot part. However, there was a problem in that the appearance was also unfavorable. The present invention solves such conventional problems, and aims to eliminate the shadow that occurs in the red-hot part of the outer flame tube above the notch of the outer tube, prevent deterioration of exhaust gas characteristics, and improve the appearance. shall be.

Means for Solving the Problems In order to solve the above problems, the combustion apparatus of the present invention is provided with a control plate provided inside the outer cylinder and above the notch.

Effect of the Invention The present invention has the above-described configuration, by suppressing the large amount of air flowing in from the ignition notch of the outer cylinder, thereby pushing the combustion position of this part upward and achieving the same combustion state as other parts in the circumferential direction. This is to prevent shadows that tend to appear in front of red-hot parts, and to improve exhaust gas characteristics and appearance.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In Fig. 1, 1 is a cylindrical lamp wick, the upper part of which is exposed during combustion in a combustion chamber 4 consisting of an inner flame tube 2 and an outer flame tube 3, and a wick guide tube 5 and an outer wick tube 6. By moving the gap up and down, the evaporation area of liquid fuel is changed and the amount of combustion is varied. - A large number of air holes 2a are provided on the side wall of the inner flame cylinder 2, a plurality of air holes 2C are provided on the top plate 2b, and a flame expansion plate 2e is provided on the upper part of the top plate 2b through a gap 2d. is installed. In addition, a large number of air holes 3a are provided on the side wall of the outer flame tube 3, and on one side of the outer flame tube 3, there is a wire mesh or punching hole having a large number of through holes 3b with a larger opening area than the air holes 3&. A red-hot part 3C made of a plate or the like is provided, a ring 7 is provided at one end of the red-hot part 3C, and a transmission tube made of heat-resistant glass or the like is placed on an outer cylinder 8 at the end of the ring 7. Holds 9. A cutout 8a for the ignition device 10 is provided on the front side of the outer cylinder 8.

A control plate 11 bent toward the outer flame tube 3 is provided inside the outer tube 8 above the notch 8a. Also, the control board 11
is integrally fixed to an outer cylinder handle 12 provided above the notch 8a on the front side of the outer cylinder 8. 13 is a shutter of the ignition device provided in the core outer cylinder 6. FIG. 2 is a partial perspective view of this embodiment.

In the above configuration, when the lamp wick 1 is ignited, combustion starts,
When the high-temperature combustion gas passes through the combustion chamber 4, an upward air current is generated, and the air necessary for combustion flows through the air holes 2a and 3a of the inner flame tube 2 and the outer flame tube 3, and the through hole 3 of the red-hot part 3c. b
, 1 m, 9 flows into the lamp wick 1, and the lamp wick 1 is supplied with a portion of this air and the heat of the flame that holds the flame in each air hole, evaporating the liquid fuel and sustaining combustion. At this time, air flowing in from the notch 8a for the ignition device 10 is suppressed by the control plate 11 provided inside the outer cylinder 8, so the air hole 3a below the outer flame gap 3 is suppressed.
By reducing the amount of combustion and raising the combustion position, it is possible to stably hold the flame even in front of the red-hot part 3c, prevent low temperature and dark shadows, - reduce the generation of carbon oxide, and improve the appearance. can also be maintained in a favorable condition.

Effects of the Invention As described above, the combustion apparatus of the present invention provides the following effects.

(1) A control plate is provided above the inside of the ignition notch in the outer cylinder, which suppresses air flowing in from the notch more than necessary.
The amount of combustion in the outer flame cylinder air hole near the notch is reduced, and combustion occurs mainly in the red-hot part above, thereby preventing the low-temperature dim shadow that occurs in the red-hot part, and - suppressing the generation of carbon oxide. It has the effect of improving exhaust gas characteristics.

(2) Since no dark shadows are generated in the red-hot area, the product is beautiful in appearance and does not cause anxiety during use.

(3) Since the control plate is integrated with the mounting of the outer cylinder handle, there is an effect that it is simple and does not require any parts for mounting.
