Abstract
Description
Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an outer burner cap for a stove burner. Background Technology
[0002] Traditional burners currently sold on the market consist of a central flame and an outer ring flame. During use, sometimes the central flame is needed, and sometimes the outer ring flame is needed. When using the outer ring flame, the flame needs to be transferred from the central flame to the outer ring flame. In order to transfer the flame, a flame transfer groove is usually set in the outer ring burner cap, through which the flame is transferred to the outer ring.
[0003] In the existing technology, the outer ring flame cap with the flame transfer groove has an excessively high flow rate of the gas mixture flowing out of the flame transfer groove during use, which makes it easy for the flame to detach or fall off during combustion, resulting in unstable combustion and difficulty in ignition transfer.
[0004] Therefore, it is necessary to improve the outer burner cap of the existing stove burner to solve the above problems. Utility Model Content

[0029] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be further described in detail to make the technical solution of this utility model easier to understand and master.
[0030] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "end", "front", "back", "center", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] Furthermore, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art. Therefore, it will not be described in detail in this embodiment.
[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0033] like Figure 1-3 As shown, an outer burner cover for a stove burner includes a cover body 1. The top of the cover body 1 is provided with a flange 2, and a through hole 4 is provided on the flange 2. The through hole 4 and the flange 2 are inclined in the horizontal direction.
[0034] Above the through hole 4, there is a flame transfer groove 3, which passes through the through hole 4 and remains in communication with it. Flame transfer holes 5 are provided on both sides of the flame transfer groove 3, and the axes of these flame transfer holes 5 form a certain angle with the axis of the through hole 4.
[0035] Each ignition port 5 is connected to a gas port 51 below it. The function of these gas ports 51 is to deliver gas to the place where combustion is required. The gas passes through the gas ports and then through the ignition ports, which also reduces the gas flow rate and stabilizes the flame combustion. Below the ignition groove 3, there are also multiple adjustment holes 7 through the through holes 4. The axis of the adjustment holes 7 is not perpendicular to the axis of the through holes 4, so that it can be used to adjust the gas flow rate and help suppress flame lift-off, effectively preventing flame lift-off or flame detachment and stabilizing the ignition.
[0036] like Figure 3-5 As shown, the inclination angle between the through hole 4 and the flange 2 in the horizontal direction is between 1° and 10°. Such an inclination angle helps to improve combustion efficiency and flame stability. In this embodiment, the inclination angle is 6°.
[0037] The angle between the axis of the ignition hole 5 and the axis of the through hole 4 is between 25° and 35°, which ensures uniform distribution and effective combustion of the gas.
[0038] To further optimize combustion, the diameter of the ignition hole 5 is designed to be smaller than that of the through hole 4, while the diameter of the gas combustion hole 51 is smaller than that of the ignition hole 5. This decreasing design helps control the flow and pressure of the gas, improving combustion stability. In this embodiment, the diameter of the ignition hole is 1.8 mm, the gas combustion hole is 1.5 mm, the through hole is 2.6 mm, and the regulating hole is 1.5 mm.
[0039] The number of adjustment holes 7 is 3 to 7. Multiple adjustment holes are set to adapt to different combustion requirements. In this embodiment, there are 5 adjustment holes 7.
[0040] Some of the regulating holes 7 are set vertically, while others are set at an angle. This controls the flow of gas, spreads the gas, and allows gas to pass through the flame transmission groove 3, which is more conducive to the transmission of flame.
[0041] The regulating hole 7 includes three types: a first regulating hole 71 that is inclined to the inside of the cover body 1, a second regulating hole 72 that is inclined to the outside of the cover body 1, and a third regulating hole 73 that is vertical along the horizontal direction of the flange 2, ensuring the diversity of gas flow.
[0042] The first adjusting hole 71 and the second adjusting hole 72 each have different tilt angles. The tilt angle of the first adjusting hole 71 is 65° to 75°, and the tilt angle of the second adjusting hole 72 is 70° to 80°. In this embodiment, the tilt angle of the first adjusting hole is 75° and the tilt angle of the second adjusting hole 72 is 70°. By providing adjusting holes, compared with the existing outer flame cover, the flame transmission speed is faster and the flame is more stable. Moreover, the adjusting holes are set with different tilt angles, which makes the uniformity of the mixture and flame in the entire flame transmission groove 3 better, and the flame transmission is better.
[0043] The third adjustment hole 73 is located opposite to the flame transfer groove 3, which reduces the gas flow rate and prevents the flame in the flame transfer groove 3 from leaving the flame, thus solving the problem of difficulty in flame transfer due to flame leaving the flame in the flame transfer groove 3.
[0044] like Figure 1 As shown, the top of the cover body 1 has an annular top wall 6, which makes the flames distributed in an annular shape. Multiple wall holes 61 are provided on this annular top wall 6.
[0045] The annular top wall 6 has multiple recesses 62 spaced apart, which serve as positioning markers.
[0046] The outer flame cap of this application is made of high-temperature resistant metal material and coated with an anti-oxidation coating. This ensures that the flame cap can maintain good performance in high-temperature environments and extend its service life.
[0047] The main technical effects of this utility model are reflected in the following aspects:
[0048] It effectively prevents flame detachment or flame loss and stabilizes flame transmission.
[0049] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
