Abstract

PURPOSE:To make it possible to control thermal power and improve thermal efficiency and thermal distribution by installing a projection only to an auxiliary burner port and the surface of a flame holding plate on the extension of the auxiliary burner port in addition to a main burner port. CONSTITUTION:The inlet of an auxiliary burner port 1-g has an area smaller than the outlet. Compared with a main burner port, it has a smaller amount of gas ejection. An auxiliary burner projection 1-h is installed on the extension of the outlet. Therefore, the flame holding 8 ejected from the auxiliary burner port 1-g collides with a projection 1-h installed in front of the outlet and it is partially divided both right and left sides, say, 8-a. At that time, the amount of gas ejected from the auxiliary burner port 1-g is smaller than the amount of gas ejected from a main burner port 1-a. Therefore, the adverse effect upon combustion is minimized. On the other hand, even when the flames ejected from the main body port 1-a may have a larger amount of gas more than usually, it is possible to prevent lifted flames by the divided flow flame 8-a of auxiliary flames 8. This construction makes it possible to obtain high output thermal power and a high throttling capacity of high TDR in spite of a small size and yet improve thermal efficiency and thermal distribution as well.

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a stove burner for a gas cooker. Conventional technology Traditionally, most burner caps have only the main flame port and ignition part, and high-calorie burners require a large burner diameter. The conventional stove burner is explained below. Figure 6 shows a cross-sectional view of a conventional stove burner. In Fig. 2, the stove burner is composed of a burner head 2 and a burner cap 1. The gas passage is opened and closed by the gas plug 4, and the gas is supplied to the burner mixing pipe 2-a through the nozzle 3 and mixed with air. The mixed gas is ejected from the main flame port 1-a and the ignition flame port 1-e formed by the burner cap 1 and the burner head 2. At this time, in conjunction with the opening/closing operation of the gas valve 4, an electric discharge is generated from the igniter 6 between the ignition plug 5 and the protrusion 11f of the burner cap, and
The gas ejected is ignited. The flame transfers to the main flame port 1-a provided on the outer peripheral surface of the burner cap, and ignition is completed. The burner cap is also provided with an inner flame opening 1-b to improve heat distribution. The air required for combustion is
It is supplied from the outer periphery of the burner and the hollow part 1-c of the burner. Problems to be Solved by the Invention However, in the conventional structure described above, when attempting to obtain an adjustable range from high output power to high TDR with a small diameter burner, it is difficult to obtain a flame that produces appropriate combustion when the power is reduced. When the mouth area is set, the amount of gas released from one main flame port increases, and the flame lifts from the main flame port. Furthermore, if a protrusion for supplementary flame is provided near the main flame outlet in order to prevent this lift, the main flame mouth flame will be disturbed and combustion will be poor. In addition, if the flame port load is set to reduce the amount of gas released from one main flame port, the flame port load will be low when the fire power is reduced, resulting in backfire, or the burner diameter will increase, resulting in poor thermal efficiency and heat distribution. It had the disadvantage that it deteriorated.

The present invention solves the above-mentioned conventional problems, and provides a stove burner with excellent thermal efficiency and heat distribution by reducing the outer diameter of the burner and making it possible to adjust the thermal power from high output thermal power to high TDR aperture. The purpose is to Means for Solving the Problems In order to achieve this object, the stove burner of the present invention has a slit-shaped main flame opening, an auxiliary flame opening, and a main flame opening formed at a constant pitch on the outer peripheral surface of the burner cap. A flame auxiliary plate is provided on the upper part of the flame auxiliary opening and the flame holding opening in the shape of a canopy, and is formed around the entire circumference of the burner cap. , which has multiple protrusions. Function: With this configuration, in addition to the main flame port, protrusions are provided only on the auxiliary flame port and the surface of the flame holding plate on the extension of the gas outlet of the auxiliary flame port, thereby achieving high output firepower and high TDR narrowing performance. Even if the amount of gas ejected from one flame port increases, part of the flame ejected from the auxiliary flame port collides with the protrusion and is split to the left and right, causing the flame at the main flame port to lift. Moreover, since the flame at the main flame port is not disturbed, combustion performance does not deteriorate. Therefore, a burner with a small outer diameter and high output can be obtained. Embodiment FIG. 1 shows a cooking stove burner according to an embodiment of the present invention. In FIG. 1, gases supplied from a nozzle 3 are mixed in a mixing tube 2-a, and are ejected from a flame port provided at the mating surface of the burner cap 1 and the burner head 2. Further, at the same time as the gas valve is opened, the igniter 6 discharges electricity, causing a spark between the ignition plug 5 and the burner plug and igniting it. The flame is located at the main flame port 1-a and flame holding port 1-g on the outer peripheral surface of the burner cap.
The fire spreads throughout the area. Figure 3 is a cross-sectional view of 1g of the auxiliary flame outlet, and the area of the auxiliary flame outlet is smaller than that of the outlet, and the amount of gas ejected is smaller than that of the main flame outlet. Furthermore, a flame reinforcement projection 1-h is provided on the extension of the outlet. Figure 4 is a cross-sectional view of the main flame port la. There is nothing obstructing the exit extension, and the flame port area is larger compared to the auxiliary flame port. Figure 5 shows the main flame port during combustion. 1-a and auxiliary flame opening 1g
and a diagram of the movement of the flame at the flame auxiliary protrusion 1-h, in which the flame 8 ejected from the auxiliary flame opening 1-g collides with the protrusion 1-h provided in front of the outlet, and part of it is split to the left and right. 8-a. At this time, since the amount of gas ejected from the auxiliary flame port 1-g is smaller than the amount of gas ejected from the main flame port 1-a, there is little adverse effect on combustion.

On the other hand, even if the flame ejected from the main flame port 1-a has a larger amount of gas than usual, lift can be prevented by the branched flame 8-a of the auxiliary flame 8. In this example, the main flame port 1-a and the auxiliary flame port 1-g are arranged alternately as shown in Fig. 2, so that it is possible to achieve high output and high TDR squeezing performance despite the small diameter. You can make a burner that is . Effects of the Invention As described above, the present invention provides a main flame port, an auxiliary flame port, and a protrusion provided at the front of the auxiliary flame port, thereby achieving high output power and high TDR despite the small outer diameter. The objective of this project is to realize an excellent stove burner that achieves the drawing performance of 100%, and also improves thermal efficiency and heat distribution.
