Description

Technical Field

[0001] The invention relates to the technical field of gas cookers, in particular to a flip-top burner. Background Art

[0002] Existing gas stove burners are mostly composed of a burner head, a gas distribution plate and a fire cover fixed on the stove panel. However, because the burner is fixedly installed on the stove panel, there are some sanitary dead corners between the burner and the stove panel, which is difficult for users to clean and very inconvenient.

[0003] Therefore, a flip-top burner has been developed on the market, which can be flipped away from the panel to clean the stove panel. However, the existing flip-top burner sets the gas nozzle on the stove panel, and aligns the inlet of the injection cavity with the gas nozzle by flipping the burner head, and uses the form of upper air intake to mix air and gas and send it into the burner head. On the one hand, this form has a related installation structure of the gas nozzle on the stove panel, which has certain sanitary dead corners and is not easy to clean; on the other hand, compared with the bottom air intake burner, there is no injection tube embedded in the stove shell, resulting in a smaller injection cavity layout space, a shorter mixing cavity stroke for mixing air and gas, a low degree of gas and air mixing, and low combustion efficiency, which needs to be improved.

[0035] Example

[0036] Reference Figures 1 to 7 The present invention provides a flip-top burner, comprising: a burner base 10 and a burner body 20;

[0037] The burner base 10 is mounted on the bottom shell of the stove, and the burner body 20 includes a rotating mounting portion 21, which is rotatably connected to the burner base 10;

[0038] The furnace head body 20 includes an outer ring ejector tube 22 and an outer ring mixing chamber 23 which are interconnected; the furnace head base 10 includes an outer ring air inlet channel 11;

[0039] An outer ring gas nozzle 12 is provided at the gas outlet end of the outer ring gas inlet passage 11. The outer ring gas nozzle 12 is arranged close to the rotating mounting portion 21 and supplies gas to the gas inlet end of the outer ring ejector pipe 22.

[0040] An outer ring fire cover 30 is installed above the outer ring mixing chamber 23. A diverter plate 40 is arranged in the outer ring mixing chamber 23. The diverter plate 40 divides the outer ring mixing chamber 23 into an outer ring first mixing chamber 231 and an outer ring second mixing chamber 232. The diverter plate 40 is provided with a plurality of first diverter connecting holes 41 arranged at intervals to connect the outer ring first mixing chamber 231 and the outer ring second mixing chamber 232.

[0041] In the present invention, the rotating mounting portion 21 provided on the burner body 20 can be rotatably mounted in the burner base 10, and the outer ring gas nozzle 12 is designed close to the rotating mounting portion 21. Compared with the traditional flip-top burner, the outer ring gas nozzle 12 is integrated in the burner base 10 and is arranged close to the rotating mounting portion 21; there is no need to add gas nozzle related structures on the panel 70, which simplifies the number of parts on the stove panel 70. The stove panel 70 has a relatively complete and continuous panel 70 area, reduces sanitary dead corners, and is convenient for users to clean the stove panel 70. In addition, through the blocking and separation of the diverter plate 40, the gas and air form a double mixing effect in the first mixing chamber and the second mixing chamber, and in the burner body 20 of the small-volume flip-top upper air inlet burner, the mixing degree of gas and air is effectively improved, thereby improving the combustion efficiency of the burner.

[0042] See also Figure 6 and Figure 7 In some embodiments of the present invention, the outer ring mixing chamber 23 is arranged in a circular groove structure, and the diverter plate 40 is arranged in a circular ring plate shape and can be placed in the outer ring mixing chamber 23 in the shape of a circular groove.

[0043] Specifically, the distribution density of the first flow diversion communicating holes 41 of the flow diversion plate 40 near the gas outlet end of the outer ring ejector tube 22 is less than the distribution density of the first flow diversion communicating holes 41 far from the gas outlet end of the outer ring ejector tube 22. The distribution density of the first flow diversion communicating holes 41 near the gas outlet end of the outer ring ejector tube 22 is smaller, and a larger proportion of the gas output by the outer ring ejector tube 22 is sent to the outer ring second mixing chamber 232 from the first flow diversion communicating holes 41 far from the gas outlet end of the outer ring ejector tube 22, so that more gas and air are mixed in the outer ring first mixing chamber 231 and then transferred to the outer ring second mixing chamber 232.

[0044] In this embodiment, the diverter plate 40 is installed on the outer ring fire cover 30 or the burner body 20 through a locking member to limit the relative position of the diverter plate 40 and the outer ring fire cover 30 or the burner body 20. Specifically, the locking member can be a bolt or a rivet.

[0045] Furthermore, the outer ring fire cover 30 and the burner body 20 are provided with a first limiting portion 31 and a second limiting portion 24 corresponding to each other, so that the outer ring fire cover 30 is installed on the burner body 20. The first limiting portion 31 and the second limiting portion 24 limit the relative position of the burner body 20 and the outer ring fire cover 30, so that the position of the diverter plate 40 meets the design requirements, and meets the design of a lower density of the first diverter communication hole 41 near the gas outlet end area of ​​the outer ring ejector tube 22.

[0046] In some embodiments, the outer ring fire cover 30 is provided with a plurality of outer ring air outlet covers 32, and the flow divider 40 is provided with a plurality of second flow divider communication holes 42 corresponding to the outer ring air outlet covers 32, and the second flow divider communication holes 42 are located below the outer ring air outlet covers 32. The outer ring air outlet covers 32 are evenly spaced on the outer ring fire cover 30, and the second communication holes can enable the first mixing chamber to stably supply gas to the upper outer ring air outlet covers 32, thereby ensuring the continuous supply of gas at the outer ring air outlet covers 32, avoiding the intermittent phenomenon or the phenomenon of fluctuating high and low flames of the outer ring air outlet covers 32, and ensuring the stability of flame combustion.

[0047] In this example, see Figures 1 to 5 The burner base 10 also includes an inner ring air inlet channel 13, and an inner ring gas nozzle 14 is provided at the gas outlet end of the inner ring air inlet channel 13. The burner body 20 also includes an inner ring ejector pipe 25, and the inner ring gas nozzle 14 supplies gas to the gas inlet end of the inner ring ejector pipe 25.

[0048] Specifically, the burner body 20 is provided with two outer ring ejector tubes 22, and the two outer ring ejector tubes 22 are located on opposite sides of the inner ring ejector tube 25. At the same time, the outer ring air inlet channel 11 and the inner ring air inlet channel 13 are independent of each other and can work independently of each other. Compared with the output of gas from one output port by one outer ring ejector tube 22, the output of gas from two output ports to the outer ring mixing chamber 23 provides more sufficient and uniform gas.

[0049] Preferably, the two outer ring ejector pipes 22 have opposite inlet flow directions for supplying gas to the outer ring mixing chamber 23. The opposite inlet flow directions of the gas can further collide and merge the gas in the outer ring mixing chamber 23, so as to enhance the unprecedented mixing effect of the gas in the outer ring mixing chamber 23.

[0050] In this embodiment, the burner base 10 includes an exposed portion 15 and a recessed portion 16; the recessed portion 16 is installed in the bottom shell of the stove and is located below the stove panel 70; the exposed portion 15 extends above the stove panel 70; the rotatable mounting portion 21 is rotatably mounted on the exposed portion 15, and the outer ring gas nozzle 12 and the inner ring gas nozzle 14 are arranged on the exposed portion 15.

[0051] Specifically, the panel 70 is provided with an embedding hole for the exposed portion 15 to extend out, and the furnace head base 10 is detachably provided with a cover plate 71 to cover the embedding hole.

[0052] In some embodiments, the inner ring gas nozzle 14 and the outer ring gas nozzle 12 are arranged at intervals, and the exposed portion 15 is provided with a mixing air supply port 50 between the inner ring gas nozzle 14 and the outer ring gas nozzle 12. The air flows to the air intake ports of the inner ring ejector pipe 25 and the outer ring ejector pipe 22 through the mixing air intake port, which is beneficial to increase the air intake amount, and further enables the gas nozzle to carry more air in the process of injecting fuel toward the ejector pipe air intake pipe, so as to increase the amount of gas and air fed, which is beneficial to improve the combustion efficiency.

[0053] Furthermore, the burner body 20 is also provided with a plurality of secondary air slots 51. Air can flow from the secondary air slots 51 to the middle of the burner to supplement the air required for the combustion of the inner ring gas, which is beneficial to improving the combustion efficiency of the burner.

[0054] In this embodiment, the burner base 10 is provided with a first support seat 17, and the burner body 20 is provided with a first support block 26. When the burner body 20 is flipped to a horizontal state, the first support block 26 abuts against the top surface of the first support seat 17. The first support seat 17 is arranged close to the rotating mounting portion 21, the top surface of the first support seat 17 is a horizontal surface, and the bottom surface of the first support block 26 is a horizontal surface; when the burner body 20 is horizontally attached to the panel 70, the first support block 26 can assist in supporting the burner body 20 by abutting against the first support seat 17.

[0055] See also Figure 2 In this embodiment, the first support seat 17 is also provided with a flip limit surface 27 which is vertically inclined; the rotating mounting portion 21 is provided with a vertical limit surface 18 which matches the flip limit surface 27; when the burner head body 20 is in a flipped and opened state, the vertical limit surface 18 can abut against the flip limit surface 27, thereby limiting the flipping angle of the burner head body 20.

[0056] In some embodiments, the burner base 10 is further provided with a second support seat 19, and the burner body 20 is provided with a second support block 28 adapted to the second support seat 19, and the second support block 28 can be clamped in the groove of the second support seat 19 to assist in supporting the burner body 20. Further, the second support block 28 is arranged near the air inlet end of the ejector tube, and the second support seat 19 is arranged near the gas nozzle, so as to ensure that the ejector tube and the gas nozzle can be aligned during operation.

[0057] The stove head body 20 further includes a stove rack 60, and a buffer pad 61 is arranged on the support leg of the stove rack 60. The buffer pad 61 arranged on the stove rack 60 can buffer the impact of the support leg of the stove rack 60 on the surface of the panel 70 when the stove head body 20 is turned over, thereby protecting the stove panel 70.

[0058] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention.
