Abstract

PURPOSE:To enable the prevention of back-fire or explosion sound by a method wherein a gas chamber is constituted by an upper part of a main body of burner having gas injection holes formed therein, an upper part of a side wall and a bottom plate. CONSTITUTION:An upper plate 1 is formed with gas injection holes 6, a side wall 2 is formed as a cylindrical body with several gas injection holes 7 being made in a flat plate and it is connected with a coupler part 8 at the upper part 1. The side wall 2 is provided with a mixing pipe 13 and a bottom part 3 is fitted to the cylindrical body so as to complete an assembly of the burner. Since a diameter of each of the gas injection holes 6 and 7 is made to have a size of 1.1mm or less, for example, the flame length is short and uniform, resulting in providing a superior efficiency of combustion. Further, since a size of the gas injection hole is small, the flame is hard to make a back-fire. Further, since a volume of gas chamber 12 is small, the remained gas is low in its volume and so no sound of diminishing of flame is generated.

Description

[Detailed Description of the Invention] This invention relates to a gas burner for a cooker that is used for grilling meat, fish, etc., or for heating cooking pots and cauldrons. The present invention relates to gas burners for cookers used in the state of the art.

In conventional gas burners for cookers of this type, when the gas ejection wall becomes red hot, the combustion speed increases, and when using city gas with low gas pressure, the burner body A re-ignites at a high temperature. At times, backfires and explosion noises occur, which impairs stable cooking.This phenomenon occurs more often when the gas ejection wall is made thinner, and this poses a problem that impedes plans to reduce the weight and cost of the ejection wall. Also, if the burner is covered with a burner cover like in a pottery, exhaust gas is less likely to be discharged than the burner cover, and the burner body A becomes hotter due to the heat reflected from the burner cover, increasing the combustion speed of the combustible gas. As a result, the amount of combustion increased, and conversely, pressure was applied to the burner body A, making it easier to backfire. In addition, it was not possible to make the boiling water thinner or raise the heat to high as in the case of boiling, and if the broth spilled, it would immediately clog the gas vents.

Therefore, the present invention has been developed to eliminate the above-mentioned problems.Even if the top surface becomes hot during use, it is possible to prevent backfire and explosion noises as described above, and to prevent the boiling liquid from falling. However, the vents were not completely blocked. Furthermore, since the combustion range is wide and the combustion efficiency is good, this gas burner for cooking devices has the advantage that you can use the same burner to cook grilled foods or hot pot dishes by simply removing the burner cover. that's why,
There is no need to install two types of burners, one for whole roasting and one for hot pot dishes. Moreover, the present invention aims to provide a gas burner for a cooker that can be used for all types of cooking.

I'm being supported.

Next, the manufacturing procedure of the burner having the above structure will be explained.

First, a large number of gas ejection holes 7f are formed in a flat plate material formed in the unfolded state as shown in Fig. 5! : To drill. The length of this flat plate material may be any length depending on the burner to be manufactured, for example, the diameter of the upper part of the burner main body (about 13 cys) (the circumference of the burner body and the circumference of the bent portion). Next, fold the flat plate material along the line 18.
At the 19.20 position, they are connected to each other in a cylindrical shape. . Next, the bending part 21 is bent outward 70 using, for example, a press device, and then connected to the joint part 8 of the upper part of the main body. This connection is performed by caulking the connecting piece 9 using the base piece 8a and the presser foot 8b of the connecting piece 8 in the direction of the arrow (C) so that it is in the state shown in Fig. 4. In this case, when the cuff mechanism is fully applied as shown by the arrow (a), the incorporeal upper part l and the retaining wall 2 become in tension, preventing the upper end of the 1flll wall 2 from escaping in the direction of the arrow (b). Therefore, the above-mentioned Cannes work can be done easily.Next, install the mixing tube 1 on the side wall.
3 as shown in FIG. The assembly of the burner is completed by inserting the bottom part 3 manufactured by press working into the lower part 2a of the rear side wall. For the burner completed as above, regulator-15
By feeding gas through the t-fitting and gas inlet 16, air is taken in through the air intake 17, and the gas and air mix in the mixing tube 13 to form a combustible gas that enters the gas chamber 12. The combustible gas in the gas chamber 12 is ejected from a large number of gas ejection holes 6.7 and combusted.

In this case, the diameter of the gas injection hole 6.7 is, for example, 1. Because it is formed to a small size, smaller than the size of a carbon fiber, the human foot is short and uniform, resulting in good combustion efficiency.Moreover, the gas nozzle is small, making it difficult to backfire.In addition, as mentioned above, ignition is required before combustion. In the case where all the combustion is carried out, the flame transfer is extremely good because a large number of gas nozzles 7 are arranged in the arrangement shown in FIG.
When the gas supply is stopped, the gas chamber 12 is configured as described above.
Since the volume of the gas is small, there is less gas left in it, so there is no sound.

As described above, in this invention, since the gas chamber 12 is configured to be able to blow out combustible gas through a large number of gas ejection holes 6.7, the IJO ': There is an advantage that the A effect can be exhibited. Further, when used for heating as described above, the upper part of the main body is heated and expanded, but in the present invention, the joint part 8 of the upper part of the main body and the joint part 9 of the upper part of the Il+lI wall are wound together. The side wall 2, which is connected in a tightening manner and configured in a hanging manner, is arranged in a cylindrical shape, so it functions as a reinforcing plate, and even if the burner reaches l'a3 temperature, the burner will not be distorted. This is prevented, and even if the broth falls, it is prevented at the joint and the gas ejection hole 7 is not clogged. Even if the burner cover is placed close to the top of the burner, only a small number of people are needed, and the burner burns completely, so it can also be used for baking. What's more, it has a revolutionary feature that allows it to burn over a wide range from small to high heat for boiling. Furthermore, even if the side wall 2 is configured in a hanging manner,
Since the bottom wall 3 of the gas chamber 12 is arranged in a raised manner so as to approach the upper part 1 of the main body, the volume of the gas chamber is small, and therefore, not only gas with a slow combustion rate but also a gas with a high combustion rate can be burned. Even when gas is combusted, backfire can be prevented, making it possible to use the desired gas.

In addition, since the side wall 2 is machined with an ejection hole 7,
It is easy to process and inexpensive.

Next, FIG. 6 shows a different embodiment of the present invention, in which the burner body is formed into a ring shape. In addition, parts that are considered to be functionally the same as those of the curved line or have an equivalent structure are designated with the same reference numerals as in the previous figure and Cf
! : The duplicate explanation has been omitted. In addition, as shown in Fig. 7, this shows an embodiment with a different mounting position of the regulator, and parts that are considered functionally the same or equivalent to those in the previous figure are designated with the same reference numerals and letters of the alphabet as in the previous figure. Duplicate explanations have been omitted by adding F.

As described above, the present invention has a configuration in which combustible gas can be blown up from the gas chamber 12 through a large number of gas ejection holes 6.7, so that it can exert a heating effect similar to the well-known gas burner for cookers. There are benefits to be gained. Furthermore, in the present invention, even if the gas ejection wall 4.5 becomes red hot due to combustion of combustible gas, backfire occurs because the gas ejection hole is small and the gas chamber is narrow. This structure prevents the flame from extinguishing or making a loud noise in that case. Moreover, the connection between the upper part of the main body and the upper part of the side wall has the advantage that the gas ejection holes 7 are not clogged.

This processing of the side wall is easy as it can be done by press 1a machining when it is in the form of a plate, and it is also possible to reduce the thickness of the plate, which has a great effect of being able to be done at a low cost in quantity. . Also, the connection between the upper part of the burner main body l and the III wall 2 can be made by explosive contact.
