Abstract

PURPOSE:To inhibit the generation of NOx sufficiently by mounting a surface combustion burner while conducting heating with excellent thermal effciency by combining the surface combustion burner and a cylindrical body. CONSTITUTION:The surface combustion burner 1 formed so as to supply a fuel gas and air, which is sufficient for completely burning the gas, to an upward combustion section 1a under a mixed state is mounted while the cylindrical body 14 inhibting outside-air natural flow toward the combustion section 1a is set up under a state that surrounds the combustion section 1a. A ridge member 15 is formed in a shape that is positioned at the upper section of the combustion section 1a and approaches so as to obstruct the flow-down of waterdrops to the combustion section 1a through transmission on the bottom surface of pans 16 placed on a trivet 17 to the bottom suface of the pans. According to this constitution, the improvement of thermal efficiency and the inhibition of generation of NOx can be conducted effectively, and the damage of the burner can also be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stove that uses various q1 combustion gases such as city gas as fuel. It is expensive and uneconomical, and generates a relatively large amount of nitrous oxides (NOX), so if you use it for a long time in a poorly ventilated room, it will cause damage to the room. There were drawbacks such as the fact that it did not allow the dirt to escape.

In view of the above-mentioned circumstances, the present invention has been made to improve the burner and its incidental structure! It is an object of the present invention to add L to effectively achieve the same thermal efficiency and suppress NOx generation, and to sufficiently prevent damage to the burner.

Next, embodiments of the present invention will be fully explained with reference to illustrative drawings.

As shown in Fig. 1, a saucer part (2) is connected to the front rkJa burner (1), and the saucer part is inserted into the opening formed on the second wall of the coos (3). (2) Gold@,
f1t, the surface combustion burner 111 is installed in the case (3) so that its earthen floor combustion part (la) is located outside of the case (3), and most of the other part is located inside the case (3).
).

To configure the burner body (lb), which has a curved throat shape, the entrance at one end of the burner main body (lb) is covered with a wire mesh or punching metal to prevent all of the mixed gas of fuel gas and air from flowing outward. Table ■ A combustion part (la) is formed to perform combustion, and an electric fan (4) is fully connected to the burner main body (ib) and the ventral opening.
An orifice (5) is arranged inside the burner body (1b), and a fuel gas supply pipe +
Connect the 6+ to the burner main body (lb), and then connect the fan (
4) For combustion from ':! ! ! The air and fuel gas from the supply pipe (6) are sufficiently mixed by the action of the orifice (5) and then supplied to the combustion section (la). Then, a zero governor (171') is applied to the fuel gas supply pipe (6), and the static pressure between the fan (4) and the orifice (6) is adjusted to the zero governor (7) in order to adjust its opening. A communication pipe t81 is provided to completely burn the fuel gas, regardless of clogging of the combustion part (la) or change in the wind cover of the fan (4), depending on the mixing ratio of the fuel gas and combustion air. Within the setting range sufficient for
8 K, and is configured to be maintained 1. Furthermore, the fuel gas supply pipe (6) - close valve (91'i Me case 3) external housing (10j) is installed in the company,
As shown in Fig. 2, the opening adjustment member tl:l of the air outlet till formed in the burner body (lb),
) is provided so as to be freely operable by an outer knob 031, and operates the on-off valve (8) when igniting and extinguishing the fire, and also controls the burner 11.
It is configured so that the heat generation Jli & N clause of 1 is performed by the operation of the fourth scale η (r part paulownia G part). To explain the light heat cover adjustment function in more detail, the air outflow violet from the outlet [1υ] is changed. Along with this, the '!I! air supply violet to the combustion section (la) is changed, and the static pressure on the upstream side of the ori-swiss (5) becomes qualitative, and the fuel gas is reduced by the action of the zero governor (7). The supply M is changed, and the outlet (6)
A maximum of four days M is set in such a state that the moxibustion of combustion '&l<(la) is as weak and stable as possible.

As shown in FIGS. 1, 8 and 4, the combustion section (la
), and a combustion part (l
a) Throw the draining member (2) shaped like a plate with an opening exposed to
The structure is such that the natural flow of outside air into the combustion section is suppressed by the action of the cylindrical body.

A trivet Uη on which copper, pots, frying pans, kettles, and other sea breams 00 are placed is
The member (151) is inserted into the notch formed in the cylindrical body (141), and is placed on the case (3) or the saucer (2) with the outer bottom placed on the saucer portion f21 for positioning. The structure is such that the water droplets flowing down towards the bottom opening of the pan placed on the trivet αη are caused to flow down towards the water 9 + component part side by the action of the inner and outer edges (15a) and (16b). Department (
The high temperature exhaust gas from la) is removed by the action of the draining member aω.
6) It is constructed so that it has an earthy texture along the bottom surface.

In addition, it is possible to construct the cylindrical retainer, the draining member Q51, and the trivet [7+] so that they can be integrally attached to and detached from the case (3), or to construct the cylindrical body and the draining member Q5+ separately. Moreover, water 9Ef! Is material 05) and trivet Uη
It is possible to configure them in one piece.

In addition, as shown in FIGS. 5 and 6, the draining member (151'f:m) has the upper edge (14a) of the cylindrical body also used as the draining member, and the trivet [17+] as the draining member. 0
It is possible to change the configuration in various ways, such as by providing 51 or using only one of them (14a) or (14a). In order to do this, use a draining member (1
It is desirable that the distance (Il) between the acting part of the trivet Q (15+) and the upper surface of the trivet Q (4 m) or (15+) be as opposite as J-6 fl.

Furthermore, the distance between the combustion part (1a) and the top surface of the trivet 0η (
l! It is undesirable to set g) to about /Ji1g in order to sufficiently suppress the generation of -carbon oxide while improving heat relief.

First, by using a surface combustion burner, the generation of NOxOx can be extremely reduced, and by adding a cylindrical cylinder, inefficiency can be sufficiently reduced.

In the above 4F, the stove according to the present invention uses fuel gas,
A surface combustion burner tl+ configured to supply the upward combustion section (la) with air and a complete mixture sufficient for complete combustion thereof is provided, and a natural flow of outside air k to the combustion section (la) is provided.
A cylindrical cone which suppresses lJ is provided to surround the combustion part (la), and is placed on the bottom surface of the tin aω placed above the trivet anrc. It is characterized by the fact that it is equipped with a water +jJ member (14 m) or a water droplet, which is arranged so as to approach the burning part (14 m) to prevent water droplets from flowing down to the combustion part (1).

That is, by providing the surface combustion burner Ill' (+-), the generation of NOx can be sufficiently suppressed and a stove with excellent hygiene can be obtained.
By combining the cylindrical body and the above-mentioned cylindrical body, it has become possible to perform heating with good thermal efficiency.

On the other hand, the combustion part (151) of the surface combustion burner tit is easily damaged if a water bottle gets on it, but as mentioned above, the combustion part (151)
4m) or α5I, it was possible to obtain a practically sufficient lifespan, and as a whole, a stove with excellent performance and durability was obtained.
