Description

Technical Field

[0001] The present invention relates to the technical field of gas stoves, in particular to a stove head and a burner therewith. Background Art

[0002] In order to improve working conditions such as backfire, the general burner head cavity is designed to be smaller, and a diversion slope is added to places such as the end of the ejector tube. This style of burner has a small cavity, which can reduce the risk of backfire and can adapt to burners that do not require strong ejection.

[0003] However, if the induced performance is enhanced while the cavity volume is reduced, the pressure at each outlet of the burner head will be uneven, resulting in a larger gas output near the burner head, making the flame larger and causing an uneven flame. In addition, the setting of the inclined surface will force the airflow to impact and change direction at this location, making the gas output near the inclined surface even larger, further affecting the flame unevenness.

[0078] As Figures 1 to 7 shown, Figure 1 a schematic diagram of the burner head provided by the present invention is shown. Figure 2 an exploded view of the burner head provided by the present invention is shown. Figure 3 a connection schematic diagram of the burner head main body 1 and the burner head lower cover 2 provided by the present invention is shown. Figure 4 a top view of the burner head main body 1 provided by the present invention is shown. Figure 5 a bottom view of the burner head main body 1 provided by the present invention is shown. Figure 6 a schematic diagram of the burner head lower cover 2 provided by the present invention is shown. Figure 7 a schematic diagram of the burner head upper cover 3 provided by the present invention is shown.

[0079] A burner head according to an embodiment of the present invention, the burner head includes:

[0080] The burner body 1 includes an outer ring groove 11 of the burner body. The outer ring groove 11 of the burner body includes an air inlet area 100, a buffer area 101 and a gas uniformity area 102. The buffer area 101 is used to slow down the flow rate of the gas input from the air inlet area 100.

[0081] The burner lower cover 2 is connected to the lower part of the burner body 1 and includes a first gas guide mechanism 21 connected to the outer ring groove 11 of the burner body;

[0082] The burner cover 3 is connected to the top of the burner body 1 and is provided with an outer ring air outlet 30 corresponding to the outer ring groove 11 of the burner body;

[0083] Among them, the outer ring groove 11 of the burner body located in the air intake area 100 is provided with a burner body outer ring groove air intake hole group 110, and the first gas guide mechanism 21 is covered on the burner body outer ring groove air intake hole group 110. The first gas guide mechanism 21 is used to transport gas to the burner body outer ring groove air intake hole group 110, so that the gas passes through the air intake area 100, the buffer zone 101 and the gas equalizing zone 102 and is output from the outer ring air outlet 30.

[0084] The present application divides the burner into three parts from top to bottom: the burner cover 3, the burner body 1, and the burner lower cover 2. To address the problem that different burners cannot balance the emissivity and the large cavity inside the burner, the burner lower cover 2 is connected to the lower part of the burner body 1, and the first gas guide mechanism 21 is covered with the gas inlet hole group 110 of the outer ring groove of the burner body. This not only allows the gas to be injected into the outer ring groove 11 of the burner body, but also increases the cavity inside the burner. It should be noted that the gas in the present application is a mixture of air and fuel gas.

[0085] In addition, from Figures 1 - 4 It can be seen that the interior of the outer ring groove 11 of the burner body is divided into an air intake area 100, a buffer area 101 and an air uniformity area 102, among which the lower part of the dotted line, i.e., the area including the air intake hole group 110 of the outer ring groove of the burner body, is the air intake area 100, the upper part of the dotted line is the air uniformity area 102, and the cavity protruding outward from the outer ring groove 11 of the burner body is the buffer area 101. The gas is transported to the air intake hole group 110 of the outer ring groove of the burner body through the first gas guide mechanism 21 to complete the initial mixing. At this time, the air-gas mixture basically forms a stable pressure and the flow rate is reduced, but there is still excess kinetic energy to break through the air uniformity area 102 and reach the buffer area 101. The function of the buffer area 101 is to collect gas with excess kinetic energy, so that the flow rate reaches a stable state after the gas comes out of the buffer area 101. If the buffer zone 101 is not provided, the excess kinetic energy of the air mixture cannot be buffered, and the air flow hits the wall surface at the junction of the air inlet area 100 and the buffer zone 101, causing the air mixture to flow around. A portion of the air mixture will escape from the outer ring air outlet 30 above the air inlet hole group 110 of the outer ring groove of the burner body, resulting in a large amount of gas at this location, uneven fire, and the occurrence of continuous flames.

[0086] The present application can increase the volume of the internal cavity of the burner head while improving the induced emission, so that the pressure of the gas is stabilized after passing through the air inlet area 100 and the buffer zone 101, and then further mixed through the gas uniformity area 102 to obtain the optimal state, and then flow out from the outer ring air outlet 30, so that the gas outlet is uniform, the flame is uniform and delicate, and there will be no continuous flame phenomenon somewhere.

[0087] In a preferred embodiment of the present invention, the outer ring groove 11 of the burner body includes a first annular wall 111, a second annular wall 112 located inside the first annular wall 111, and a bottom wall 113 of the outer ring groove of the burner body. The air inlet hole group 110 of the outer ring groove of the burner body includes:

[0088] The first burner body outer ring groove air inlet hole 1101 is provided on the burner body outer ring groove bottom wall 113;

[0089] The second burner body outer ring groove air inlet hole is provided on the first annular wall 111 and is connected to one side of the first burner body outer ring groove air inlet hole 1101;

[0090] The air inlet hole of the outer ring groove of the second furnace head body is arc-shaped, and the air inlet area of the outer ring groove 11 of the furnace head body is increased through the air inlet hole 1101 of the outer ring groove of the first furnace head body and the air inlet hole of the second furnace head body.

[0091] like Figures 2 - 5 As shown, compared with the structure of the traditional burner air inlet, the second burner main body outer ring groove air inlet hole is opened on the first annular wall 111 and the first burner main body outer ring groove air inlet hole 1101 is opened on the bottom wall 113 of the burner main body outer ring groove to increase the air intake area, quickly reduce the gas flow rate, and quickly fill the cavity.

[0092] In a preferred embodiment of the present invention, the lower portion of the first annular wall 111, which is adjacent to the other side of the air inlet hole 1101 of the outer annular groove of the first furnace body, bulges outward to form a first annular wall groove 1111. The first air guide mechanism 21 includes:

[0093] The upper shell 211 has a downward-opening arc-shaped longitudinal section and is fixed to the outer periphery of the first annular wall 111 near the air inlet hole of the outer ring groove of the second furnace head body;

[0094] The lower shell 212 has a lower shell opening at its top, including a first lower shell groove 2121 corresponding to the first annular wall groove 1111, a second lower shell groove 2122 corresponding to the air inlet hole 1101 of the outer ring groove of the first furnace body, and a third lower shell groove 2123 corresponding to the upper shell 211. The longitudinal sections of the second lower shell groove 2122 and the third lower shell groove 2123 are both U-shaped.

[0095] The inner cavity of the first annular wall groove 1111 forms a buffer zone 101 , and the upper shell 211 is matched with the third lower shell groove 2123 to form an outer ejection tube 210 for ejecting gas.

[0096] like Figures 1 - 3 As shown in Figure 6, the first gas guide mechanism 21 is divided into two parts: an upper shell 211 and a lower shell 212. The lower shell 212 includes a first lower shell groove 2121, a second lower shell groove 2122 and a third lower shell groove 2123. The shapes of the upper shell 211 and the third lower shell groove 2123 match each other and can form an external ejection tube 210 for ejecting gas.

[0097] In addition, in the present application, the first lower shell groove 2121, the second lower shell groove 2122 and the third lower shell groove 2123 are integrally formed, which can quickly inject the gas in the third lower shell groove 2123 into the first lower shell groove 2121 and the second lower shell groove 2122. In addition, the notch of the first lower shell groove 2121 and the notch of the second lower shell groove 2122 are both located at the top and the longitudinal cross-sections are both U-shaped. The notch of the first lower shell groove 2121 and the second lower shell groove 2122 are respectively covered on the first annular wall groove 1111 and the first burner body outer ring groove air inlet hole 1101, which can increase the gas storage capacity of the outer ring channel of the burner and increase the volume of the internal cavity of the burner.

[0098] In a preferred embodiment of the present invention, the burner body 1 further comprises:

[0099] The first cylinder 12 is located inside the second annular wall 112;

[0100] a connecting plate 13 connecting the second annular wall 112 and the first cylinder 12;

[0101] Among them, a second annular wall through hole is opened at the lower part of the second annular wall 112 near the air inlet hole 1101 of the outer ring groove of the first furnace head body, and the connecting plate 13 is connected to the hole wall of the second annular wall through hole to increase the gas storage capacity of the outer ring groove 11 of the furnace head body.

[0102] In a preferred embodiment of the present invention, the second annular wall through hole and the connecting plate 13 respectively include a vertical section 131 and a horizontal section 132 fixed to the top of the vertical section 131 , wherein the vertical section 131 is tangentially connected to the outer periphery of the first cylinder 12 .

[0103] like Figures 2 - 5As shown, the longitudinal section of the connecting plate 13 of the present application is an inverted L shape. By setting the connecting plate 13, the gas storage capacity of the outer ring groove 11 of the burner head body is increased. Especially when the vertical section 131 is tangentially connected to the outer periphery of the first cylinder 12, the gas storage capacity of the outer ring groove 11 of the burner head body can be increased to the maximum. In addition, since the connecting plate 13 is located in the intake area 100, the gas, air, and fuel gas entering the outer ring groove 11 of the burner head body can be fully and evenly mixed.

[0126] The inner flame cover 6, covering the burner divider inner ring groove 42;

[0127] Wherein, the burner divider outer ring groove 41 is provided with a burner divider outer ring groove through hole corresponding thereto, and the burner divider inner ring groove 42 is provided with a burner divider inner ring groove through hole 441 corresponding to the inner ring air outlet hole 300.

[0128] Wherein, the burner divider 4 is installed on the burner head, the burner divider outer ring groove 41 corresponds to the outer ring groove 11 of the burner head body, the outer flame cover 5 covers the burner divider outer ring groove 41, and the inner flame cover 6 covers the tops of the third cylinder 31 and the fourth cylinder 32. In this way, a part of the uniform gas output by the burner head enters the burner divider outer ring groove 41 through the outer ring air outlet hole 30 and the burner divider outer ring groove through hole and is ejected by the outer flame cover 5, and a part of the gas enters the burner divider inner ring groove 42 through the inner ring air outlet hole 300 and the burner divider inner ring groove through hole 441 and is ejected by the inner flame cover 6 after that. The burner in this embodiment includes a burner head of any of the above types. Since the above burner head has the above technical effects, the burner having the above cock valve should also have the same technical effects.

[0129] In a preferred embodiment of the present invention, the outer flame cover 5 includes an outer flame cover inner wall 51, and the outer flame cover inner wall 51 has a conical structure. Wherein, a plurality of outer flame cover air outlet groups 52 are provided on the outer flame cover inner wall 51, and the plurality of outer flame cover air outlet groups 52 are uniformly distributed along the outer flame cover inner wall 51.

[0130] As Figures 7 - 8 shown, the air outlet direction of the outer flame cover air outlet group 52 forms a certain angle with the vertical direction. Coupled with the conical structure of the outer flame cover inner wall 51, it enables the flame to form a rotating air flow and shoot out on the outer flame cover inner wall 51, and can make the outer flame cover 5 eject an inner-rotating inner-flame type flame. Because the flame combustion density is low and the flame has an upward velocity, the overall flame burns upward in a spiral shape similar to a tornado rotating around the center.

[0131] In a preferred embodiment of the present invention, the outer fire cover air outlet hole group 52 includes a first outer fire cover air outlet hole 521 and a second outer fire cover air outlet hole 522. The height of the first outer fire cover air outlet hole 521 is greater than the height of the second outer fire cover air outlet hole 522.
