Description

  In the present invention, when a pilot gas burner attached to a commercial gas range is not used, oil smoke, dust, or the like is contained in the gas outlet with a small diameter at the back of the pilot gas burner from the tip opening of the seed flame outlet. The present invention relates to an auxiliary instrument for a pilot gas burner that reduces the amount of oil that enters and accumulates and clogs and extends the use time (life) of the pilot gas burner.

  As a method for extending the life of a conventional pilot gas burner, there is a method related to a gun burner for a fluidized incineration system. For example, Patent Document 1 provides a partition plate on the front and rear sides, and a single pilot means to reduce the space in the pipe. A structure is shown that extends the life of the pilot gas burner by ensuring it wide.

  In a commercial gas range, there is a document (for example, refer to Patent Document 2) in which a partition plate is provided so that oil smoke from an object to be cooked does not contact the combustion surface of the burner during cooking, but a pilot gas burner is not used. Occasionally, oil smoke or dust enters the narrow gas outlet from the tip opening of the pilot gas burner seed fire outlet, accumulates as oil or dust, and gradually closes the diameter. However, there is no literature for the purpose of improving the problem of use time (lifetime) such that the blowing of the seed fire cannot be maintained and the ignition of the commercial gas range becomes impossible.

  If this problem occurs after a certain period of use and the condition of the fire is worsening, the pilot gas burner must be replaced with a new one, or the main burner can only be ignited using a torch type lighter. Yes, in the replacement method, it is necessary to ask a specialist to disassemble a part of the existing commercial gas range and replace the pilot gas burner, which causes problems such as cost and time, and directly ignites In the method, the main burner of the commercial gas range also has the problem that it is troublesome to ignite using a torch type lighter every time it is used.

  The present invention has been made in view of such circumstances, and a connection part for detachably attaching to a pilot gas burner attached to a commercial gas range, and a pilot gas burner when the pilot gas burner is not used. A shield installed in front of the tip opening of the seed fire outlet to prevent oil smoke, dust, etc. from entering from the tip opening of the seed fire outlet, and the tip opening and shielding of the seed fire outlet. An auxiliary instrument for a pilot gas burner provided with a stopper for determining the installation distance between the parts is proposed.

  By installing the pilot gas burner auxiliary equipment on the pilot gas burner, when the pilot gas burner is not in use, oil smoke and dust, etc., from the tip opening of the pilot gas burner's seed flame outlet will have a narrow diameter gas outlet. Improves the problem that the gas gas outlet is gradually blocked up, and the fire of the gas fire cannot be maintained, making it impossible to ignite the commercial gas range. Yes, it can extend the usage time (life). In addition, when oil smoke or dust accumulates on the shield as oil or dust, it can be removed and removed, washed and removed, and it can be used again and again, so the cost and labor of replacing the pilot gas burner Is reduced.

  The present invention relates to an elastically deformable connecting portion that can detachably attach and fix an auxiliary instrument for pilot gas burner to the outer peripheral portion of a substantially cylindrical pilot gas burner, and a pilot gas burner blowout when the commercial gas range is not used In order to prevent oil smoke or dust from entering the opening at the tip of the mouth and entering the narrow gas outlet at the back of the opening and closing or narrowing the diameter, Provided facing the inner side of the substantially cylindrical portion of the auxiliary instrument for pilot gas burner so that the shielding portion installed in front of the tip opening portion and the position between the tip opening portion and the shielding portion are set in advance. The present invention relates to an auxiliary instrument for a pilot gas burner provided with a stopper.

  Stainless steel was used as the material, but the temperature around the gas range was about 400 ° C with both the pilot gas burner and the gas range main burner ignited. A heat-resistant steel other than steel or a non-ferrous heat-resistant material may be used.

  Hereinafter, an embodiment of an auxiliary instrument 1 for a pilot gas burner according to the present invention will be described with reference to FIGS. 1 to 6 and Table 1. FIG.

  The connecting portion 9 is composed of an inner diameter 7 (see FIG. 6) of a substantially cylindrical portion and a notch portion 2 (see FIG. 6) provided in a part thereof, and the connecting method is the pilot gas burner auxiliary instrument 1 (FIG. 1, FIG. 1). The inner diameter 7 of the substantially cylindrical portion (see 3, 5, 6) is made slightly smaller than the outer diameter of the substantially cylindrical pilot gas burner 6 (see FIGS. 1 and 2), and a notch 2 is formed in a part thereof. Is inserted into the pilot gas burner 6 from the notch 2, the substantially cylindrical portion of the pilot gas burner auxiliary instrument 1 is elastically deformed, and the outer periphery of the pilot gas burner 6 is sandwiched between the pilot gas burner auxiliary instrument 1. It is detachably mounted and fixed. In addition, a detachable connection method such as fixing with a bolt nut or a band may be used.

In order to prevent intrusion of oily smoke, dust, etc., the periphery of the tip opening 5 (see FIG. 2) of the pilot gas outlet of the pilot gas burner 6 is almost covered with the auxiliary instrument 1 for pilot gas burner (see FIG. 1). However, the shielding part 3 prevents oil smoke, dust, etc. generated in the vicinity when the commercial gas range is not used from entering the pilot gas burner 6 from the tip opening part 5 of the pilot gas outlet and uses the commercial gas range. Sometimes there are two contradictory functions of igniting the pilot fire coming out from the tip opening 5 of the pilot gas outlet of the pilot gas burner 6 so as not to interfere with the ignition of the main burner. The aperture ratio, opening, installation position, and cross-sectional shape are important.
In particular, the shielding portion 3 provided in front of the tip opening 5 of the seed fire outlet has an opening ratio (from the center line of the diameter of the tip opening 5 through the shielding portion 3 in order to make the seed fire easily reach the vicinity of the main burner. When the area of the tip opening 5 of the seed fire outlet is viewed, the area of the tip opening 5 of the seed fire outlet that is visible without being obstructed by the shield 3 is the area of the tip opening 5 of the seed fire outlet. Opening ratio (%) = 100 × [(Area of tip opening 5) − (Area of tip opening 5 covered by shielding part)] / (Area of tip opening 5)) Is preferably 40% to 60% in consideration of the degree of shielding and the ease of arrival of the fire.
Furthermore, the cross-sectional shape of the shielding part 3 is creased in the longitudinal direction of the flat plate so as to form a convex V-shape (see FIG. 4) toward the tip opening 5 of the seed fire outlet from which the seed fire comes out, and , Its opening (a shape opened at equal angles to both sides with respect to the center line of the diameter of the tip opening 5 of the seed fire outlet. Taking into account the shielding effect of oily smoke, dust, etc., the fan-shaped shape is good from 90 degrees to 150 degrees, and the installation distance is the same along the center line of the diameter of the tip opening 5 of the pilot gas blower outlet of the pilot gas burner. If it exists in the range of 5 mm to 10 mm from the part 5, there will be no problem in the ignition effect of a main burner, and shielding effects, such as oil smoke. In addition, the shielding part 3 may use a plurality of strip-like short thin plates, a wire net, or punch metal instead of the thin plate, and the thinner the better. For example, a thickness of 0.5 mm to 1.0 mm is suitable because it is inexpensive, easily available, and easy to process.
Note that the side cover 8 (see FIG. 1) also covers the periphery of the tip opening 5 of the seed fire outlet in order to prevent intrusion of oily smoke, dust and the like from other than the vicinity of the shield 3.

  The stoppers 4 (refer to FIGS. 1, 5 and 6) are a set (two) of opposingly provided inner diameter 7 side of the substantially cylindrical portion of the auxiliary instrument 1 for pilot gas burner, that is, facing the inner side of the substantially cylindrical portion. It is a convex projection, and is made to a height of about 1 to 2 mm by pressing or the like. After the pilot gas burner auxiliary device 1 is attached to the pilot gas burner 6, the pilot gas burner auxiliary device 1 is installed. When adjusting the position, the pilot gas burner 6 is in contact with the tip opening 5 of the seed fire outlet, so that it cannot be moved any further. This is to secure a distance between the two.

Next, the experimental results in Table 1 will be described. An example of the pilot gas burner 6 becoming unusable in about 6 months at a store that is prosperous and always operates a commercial gas range without the pilot gas burner auxiliary equipment 1 installed, based on daily work experience. Although there are many cases where it is not prosperous, but there are many cases where it becomes unusable in about 12 months even in stores that operate a commercial gas range every day. Is the experimental result of the state of ignition of the main burner after 12 months of use. The relationship between the opening ratio of the shielding part 3, the opening of the cross-sectional shape of the shielding part 3, and the installation distance between the shielding part 3 and the tip opening part 5 of the pilot fire outlet is summarized by the difference in the ignition condition of the main burner. The igniting momentum remains unchanged and the main burner is well ignited. “◎”, the igniting momentum is weak but the main burner is ignited. A state where the fire blinks and the main burner cannot be ignited is indicated by “Δ”, and a state where the type fire is not ignited and the main burner cannot be ignited is indicated by “×”. In this experiment, a new commercial gas range was used, and the pilot gas burner and main burner gas were always fully open for 12 months.

  Table 1 shows the results of experiments performed with the opening ratio of the shielding part 3 being 30% to 70%, the opening degree being 80 degrees to 160 degrees, and the installation distance being 3 mm to 15 mm. Even after 12 months of use, it was found that when the aperture ratio was set to 40% to 60%, the opening degree was set to 90 ° to 150 °, and the installation distance was set to 5 mm to 10 mm, the main burner was stably ignited. Moreover, when it set other than the above, it became an unstable result as shown in Table 1, respectively. Therefore, within the range of “◎” in Table 1, it is possible to extend the life by reducing clogging of the pilot gas burner outlet of the pilot gas burner due to intrusion of oil smoke, dust or the like when not ignited.
