Abstract

PURPOSE:To stabilize combustion and to prevent uneven heating of a combustion sleeve, tilting the inner peripheral part of a flange formed at an upper part of an outer sleeve toward the inner surface of a tansparent sleeve. CONSTITUTION:An apparatus of this invention comprises an outer combustion sleeve 2 and an inner combustion sleeve 1 formed with many air supply holes 18, and an outer barrel 3 surrounding the lower part of the outer combustion sleeve 2 is fixed to the inner and outer combustion sleeve 1, 2 concentrically by means of cross pins 4. Further, a transparent barrel 5 made of glass is placed on a flange 6 formed at the top of the outer barrel 3 in the manner taht it surrounds the upper part of the outer combustion sleeve 2. Here, the inner peripheral part of the flange 6 at the top of the outer barrel 3 is folded upward toward the inner surface of the transparent barrel 5 as shown at 20 in the drawing. By employing such an arrangement, air introduced into the space formed between the transparent barrel 5 and the outer combustion sleeve 2 via the flange part 6 is enabled to flow smoothly. Therefore, it is enabled to stabilize combustion of fuel and to prevent uneven heating of the combustion sleeves.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a petroleum gas tank 1 in which the outer periphery of an outer flame cylinder is surrounded by a transparent cylinder.
Concerning Zo/Bena. This kind of burner was published in Japanese Patent Application Publication No. 54-4
As described in Publication No. 5836, etc., the flange portion provided between the outer tube and the transparent tube is the cauterization 7'//! fixed,
This has a great effect on the uniformity of the red-hot state.For this reason, conventionally, as shown in JP-A No. 54-45836, the flange portion has been filled with water 31' to have a favorable effect on the combustion state. It's just a thing.
,Ta.

The present invention has been made to eliminate such drawbacks.

An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 is a partially cutaway perspective view of the burner of the present invention, and Fig. 2 is a v
11, schematic cross-section 17i1, and FIG. 3 are fragmentary side views of essential parts.

In the figure, 1 is an inner flame tube with a large number of air supply holes 18, 2 is an outer flame tube, and 3 is an outer tube that surrounds the outer circumference of the lower part of the outer flame tube 2, and is arranged concentrically with the inner and outer flame tubes 1°2 by a cross bin 4. Fixed. Reference numeral 5 is an IH wire made of glass that is fitted onto the -1 end flange portion 6 of the outer cylinder 3 and runs around the upper outer periphery of the outer flame cylinder 2. Reference numeral 7 denotes a link-shaped glass plate fitted and attached between the upper end of the transparent cylinder 5 and the upper end of the outer flame cylinder 2, and as shown in FIG. 4, an air vent 8. 89 is a partial ventilation hole plate, 10 is an upper plate, and 11 is an incandescent coil surrounded by one end of the raising part ventilation hole plate, and the outer periphery of the incandescent coil and the outer flame are arranged almost uniformly. A slight gap 12 is provided between the upper end of the cylinder 2 and the upper end of the cylinder 2, as shown in FIG.

'' - There are many air supply holes in the outer flame quotient 2, but as shown in No. 31 I, the diameter of the upper air supply hole 13 is larger than that of the air supply hole 14 in the section '1'. The heat capacity of the outer flame cylinder 2 is smaller in the upper part, and it is more likely to become red hot. As shown in Fig. 2, the outer flame tube 2 has an inner lli' at one end.
A bead 115 is formed so that the heat generated during combustion is sufficiently distributed around the outer flame tube 2 without escaping to a part of the combustion chamber, thereby preventing uneven red heat. The strength of the outer flame cylinder 2 is increased, the roundness is stabilized, and the air supply balance is improved.

In history, what about the outer flame surface 12 part that is circumferential to the outer cylinder 3? Since the M number of beats '16 are formed outward, the outer flame tube 2
This improves the psychogenicity of baking soda, and the space between the baking soda outer cylinder 3 and the inner flame cylinder 1 is always constant and empty (the balance of inflow is stable and uneven combustion is eliminated. This is to balance the air flowing in from the inner flame tube 1) (and the air flowing in from the outer flame tube 3 side).In particular, by changing the height of the heat 16, the amount of air flowing through the outer needle 13 can be easily adjusted. Can be adjusted.

In addition, in FIG. 2, heat-16 is indicated by the dotted line Il++
If it is placed on the inside, it will have the same effect as when the gap between the combustion parts is made smaller, and the release of the moon oil can be freely changed within a certain range. Further, even if the transparent body 5 is provided with a bead 1-'' at the portion 411, &;

In addition, as shown in FIG. 3, an air supply hole is provided in the upper flange portion 6 of the outer cylinder 3 (i.e., the connecting part between the transparent cylinder 5 and the outer cylinder 3), and in the corresponding part A of the outer flame cylinder 2. By not providing this, the combustion 4J'8 in this part A is suppressed, and the l j'? l(

Therefore, the vaporized Q17t of kerosene does not increase abnormally and combustion is stabilized, preventing the A'lI゛flame phenomenon during extinguishing.11. can do.

Introduction of the part corresponding to the outer cylinder 3 fC (Ll4) As shown in Fig. 3, by increasing the pitch of all holes in the middle part, sufficient air can be sent in at the time of ignition, and the red ρ of the outer flame cylinder 2 can be increased. (Lf<), and odor generation can be suppressed.

As shown in Fig. 6(a), the two-part flange part 6 of ``3'' outside the old description has a bright part 5 with ``:/: )-''(' 20) on its inner peripheral edge.

The flow becomes smooth and the combustion+Ctl becomes stable. If the vertical plane 21 is vertically 1'/', -r as shown in FIG. 6(b), turbulence will occur in the air 2J as shown in the figure, and the state ζ firing will become stable.

! According to the burner of the present invention described above, since the gap 12 is provided between the incandescent coil 11 and the outer flame tubes 2, , I', 4j, the combustion tube rising 111 from the 1.degree. Since the degree of cooling by the coil 11 is small, the generation of waste gas is reduced, and the extension of the flame to a part of the burner can also be suppressed. According to the present invention, the glass presser foot 7
As shown in Figure 7(a), since the air vent 8 is provided, the air pressure from the inside of the inner flame and the air pressure horn from the outer flame tube 2) are balanced. It is possible to prevent uneven red heat of the flame tube 2.

As shown in Figure 5, if the entire hole pitch of 8 is made thicker in the middle part, As the amount of air supplied increases, the red-hot temperature of the red-hot part B of the outer flame tube 2 becomes higher, and the red-hot effect becomes higher. Also, inner flame tube 1
By providing the bead F19 in the outer flame cylinder 2, the amount of heat generated during combustion becomes difficult to partially escape, and the red-hot temperature of the outer flame cylinder 2 can be further increased.

As shown in Section 2, according to the present invention, the inner peripheral edge of the upper flange of the outer cylinder is inclined toward the inner surface of the transparent IF; 11. Air flowing into the stove flows to stabilize the flame ε and prevent uneven red heat. do.
