Description

Technical Field

[0001] This application relates to the field of burners for gas stoves, and more particularly to an inner ring burner cap and burner. Background Technology

[0002] Currently, many household gas stoves use multi-ring burners, commonly two-ring or three-ring burners. For example, a three-ring burner includes a burner base, on which are installed an inner ring injector, a middle ring injector, and an outer ring injector. The burner base has an inner ring channel, a middle ring channel, and an outer ring channel. The inner ring channel is connected to the inner ring injector, the middle ring channel is connected to the middle ring injector, and the outer ring channel is connected to the outer ring injector. A mixing chamber is installed on the burner base, which has an inner ring mixing chamber, a middle ring mixing chamber, and an outer ring mixing chamber. The inner ring mixing chamber is connected to the inner ring channel, the middle ring mixing chamber is connected to the middle ring channel, and the outer ring mixing chamber is connected to the outer ring channel. Correspondingly, the burner cap includes an inner ring cap, a middle ring cap, and an outer ring cap, which are respectively located above the inner ring mixing chamber, the middle ring mixing chamber, and the outer ring mixing chamber.

[0003] In the application of burners, high efficiency and energy saving have always been the goals of the country's promotion of low-carbon and environmental protection and a selling point favored by consumers. At present, high-efficiency burners on the market often focus too much on thermal efficiency and ignore the essential practicality of the product. For example, they drill flame holes directly on the top surface of the burner cap or drill flame holes on the bevel. As a result, if soup or oil spills during cooking, the soup or oil will block the flame holes and even block the ignition channel, thus affecting the combustion conditions and service life.

[0047] This application provides an inner ring fire cap. Figure 1 This is a schematic diagram of an inner ring flame cap provided in an embodiment of this application. Figure 1 , Figure 1 This is a cross-sectional view of the inner ring flame cap, as shown below. Figure 1 As shown, the inner ring flame cap includes an inner ring flame cap body 11 and a liquid holding device 12.

[0048] like Figure 1 As shown, the aforementioned inner ring flame cap body 11 includes a top flame hole 111 disposed on the top of the inner ring flame cap body 11. Figure 1 The diagram shows a portion of the top flame hole 111. Optionally, the liquid-holding device 12 is disposed inside the inner ring flame cap body 11, and the position of the liquid-holding device 12 inside the inner ring flame cap body 11 corresponds to the position of the top flame hole 111 on the inner ring flame cap body 11. Optionally, an airflow channel exists between the space above the liquid-holding device 12 and the space below the liquid-holding device 12.

[0049] Figure 2 This is a schematic diagram of an inner ring flame cap provided in an embodiment of this application. Figure 2 , Figure 2 yes Figure 1 An exploded view of the components in the inner ring fire cap. Figure 2As shown, the top flame holes 111 are mainly concentrated within a small circle on the inner ring flame cap body 11. Considering the need for an airflow channel between the space above and below the liquid-holding device 12, in some possible embodiments, the position of the liquid-holding device 12 inside the inner ring flame cap body 11 and the position of the top flame holes 111 on the inner ring flame cap body 11 correspond as follows: the position of the liquid-holding device 12 inside the inner ring flame cap body 11 is exactly below the small circle where the top flame holes 111 are concentrated, and from a top-down view, the top-down area of ​​the liquid-holding device 12 is exactly equal to or greater than the area of ​​the small circle. Thus, liquids such as soup and oil dripping from the top flame holes 111 fall directly into the liquid-holding device 12.

[0050] Optionally, to allow liquids and oil to drip smoothly through the top flame hole 111 into the liquid-collecting device 12, the diameter of the top flame hole 111 can range from 1.5 mm to 2.5 mm. Optionally, the diameter of the top flame hole 111 can be 1.5 mm, or 2.5 mm, or 2.0 mm. Optionally, all top flame holes 111 can have a uniform diameter. Optionally, the diameter of the top flame holes 111 can be non-uniform.

[0051] In this embodiment, the inner ring burner cap and the inner ring burner cap seat on the burner are fastened together to form an inner ring chamber. In an optional embodiment, an airflow injection port is provided at the bottom of the inner ring burner cap seat, and the airflow injection port is connected to the injection tube. If there is no liquid-collecting device 12 to catch the soup and oil dripping through the top flame hole 111, the soup and oil can easily enter the injection tube, clogging the nozzle and channel, thereby shortening the service life of the burner.

[0052] Figure 3 This is a schematic diagram of an inner ring flame cap provided in an embodiment of this application. Figure 3 , Figure 3 This is a cross-sectional view of the exploded inner ring fire cap, such as... Figure 3 As shown, except Figure 1 Regarding the aforementioned content, the inner ring flame cap body 11 also includes a side flame hole 112 disposed on the side. Figure 3 Part of the side flame port 112 is shown in the figure. The side flame port 112 is used to guide gas from below the liquid container 12 to the side flame port 112.

[0053] Optionally, the side flame holes 112 can be evenly distributed on the side of the inner ring burner body 11, and the number of side flame holes 112 surrounding the side of the inner ring burner body 11 can be one ring or multiple rings. Among them, multiple rings of side flame holes 112 can allow the gas to exit from more outlets.

[0054] Optionally, all side flame holes 112 can have a uniform diameter. Alternatively, the diameter of the side flame holes 112 can be non-uniform.

[0055] like Figure 3 As shown, the liquid-containing device 12 includes a gas guiding structure 121 circled in dashed lines. Optionally, the entire liquid-containing device 12 can be considered as a gas guiding structure 121. In an optional embodiment, the gas guiding structure 121 includes a guiding bottom 1211 and guiding edges 1212 disposed around the guiding bottom 1211, wherein the angle between the guiding bottom 1211 and the guiding edges 1212 is an acute angle. Specifically, the angle between the extension lines of the guiding edges 1212 and the guiding bottom 1211 is an acute angle.

[0056] Optionally, the gas guiding structure 121 can be as follows: Figure 3 The diagram shows a "disc" shaped structure, in which the bottom of the guide 1211 is flat, and the guide edge 1212 surrounds the guide edge 1212.

[0057] Optionally, the gas guiding structure 121 can be a "pointed-bottom pot" type structure.

[0058] In the embodiments of this application, Figure 4 This is a schematic diagram of the gas flow path within the inner ring flame cap provided in an embodiment of this application, as shown below. Figure 4 The gas flow path shown is such that when the bottom of the inner ring burner cap is provided with a gas flow injection port, and the gas flow injection port is connected to the injection tube, the gas flow in the burner is injected into the gas flow injection port through the injection tube. A large amount of gas flow then impacts the bottom of the liquid-containing device 12 and the guide edge 1212. Due to the guiding effect of the gas guiding structure 121 formed by the bottom of the flow and the guide edge 1212, the gas first reaches the side flame hole 112 of the inner ring burner cap. Subsequently, the remaining gas passes through the airflow channel between the upper space and the lower space of the liquid-containing device 12 and arrives below the top flame hole 111. This implementation method allows the gas to have more sufficient contact with secondary air before exiting the flame hole, thereby improving thermal efficiency, and also reduces the risk of backfire.

[0059] In this embodiment, the liquid-containing device 12 disposed in the inner ring burner cap can prevent the airflow from the burner from reaching the top burner hole 111 first and then the side burner hole 112, thus avoiding the risk of backfire. Optionally, the risk of backfire is caused by the secondary air at the top being more abundant than that at the side, resulting in a combustion rate greater than the velocity of the gas mixture exiting the burner hole.

[0060] In an alternative embodiment, the liquid-containing device 12 may be permanently fixed inside the inner ring flame cap body 11.

[0061] In another optional embodiment, when soup or oil drips into the liquid-collecting device 12, the water in the device 12 will evaporate under high temperature, leaving the oil residue. To make the liquid-collecting device 12 easier to clean and ensure the product's lifespan, such as... Figure 3 As shown, the connection between the liquid holding device 12 and the inner ring flame cap body 11 is a detachable connection.

[0062] In this embodiment of the application, the liquid holding device 12 may include a first support member, and the inner ring flame cap body 11 may include a second support member. The liquid holding device 12 can be disposed inside the inner ring flame cap body 11 through the first support member and the second support member.

[0063] Figure 5 This is a schematic diagram of an inner ring flame cap provided in an embodiment of this application. Figure 4 , Figure 5 This is a cross-sectional view of the inner ring flame cap, as shown below. Figure 5 As shown, the first support member in the liquid holding device 12 may include a support frame 122, and the second support member in the inner ring flame cap body 11 may include a first mounting hole 113 and a second mounting hole 114 provided in the inner ring flame cap body 11.

[0064] like Figure 5 As shown, one end of the support frame 122 is installed in the first mounting hole 113, and the other end of the support frame 122 is installed in the second mounting hole 114.

[0065] Figure 6 This is a schematic diagram of a liquid-holding device 12 provided in an embodiment of this application, as shown below. Figure 6 As shown, the gas guiding structure 121 in the liquid holding device 12 described above can also be referred to as a liquid holding chamber. The wall of the liquid holding chamber can have two holes, through which the support frame 122 passes the liquid holding chamber. Subsequently, one end of the support frame 122 is installed in the first mounting hole 113, and the other end of the support frame 122 is installed in the second mounting hole 114.

[0066] In some possible embodiments, two support frames 122 may be welded at two symmetrical positions on the outer wall of the liquid-containing cavity, and the two open ends of the two support frames 122 may be installed in the first mounting hole 113 and the second mounting hole 114, respectively.

[0067] In some possible embodiments, the support frame 122 may be elastic to facilitate installation of the support frame 122 in the first mounting hole 113 and the second mounting hole 114. When the support frame 122 is subjected to force, for example... Figure 6When the midpoint of the support frame 122 is subjected to a force toward the bottom of the liquid-containing device 12, the straight-line distance between the two endpoints of the support frame 122 will shorten. At this time, the two ends of the support frame 122 can be aligned with the first mounting hole 113 and the second mounting hole 114. Subsequently, when the support frame 122 is not under force and is in a relaxed state, the two ends of the support frame 122 can be inserted into the first mounting hole 113 and the second mounting hole 114. In this way, the liquid-containing device 12 is installed on the inner ring flame cap body 11.

[0068] Similarly, the process of removing the liquid-containing device 12 from the inner ring flame cap body 11 can also be obtained, which will not be described in detail here.

[0069] In some alternative embodiments, the liquid holding device 12 may include a support frame 122 made of a high-temperature and corrosion-resistant metal, such as copper or iron, or an alloy.

[0070] This application also provides a burner that includes the aforementioned inner ring flame cap.

[0071] Figure 7 This is a schematic diagram of a burner provided in an embodiment of this application, as shown below. Figure 7 As shown, it includes an inner ring flame cap 1, an outer ring flame cap 2, and a flame cap seat 3.

[0072] Figure 8 and Figure 9 This is a schematic diagram of a burner provided in an embodiment of this application. Figure 8 and Figure 9 for Figure 7 The exploded views are from two perspectives. The flame cap seat 3 includes an inner ring flame cap seat 31 and an outer ring flame cap seat 32. The inner ring flame cap 1 and the inner ring flame cap seat 31 are fastened together to form an inner ring chamber, and the outer ring flame cap 2 and the outer ring flame cap seat 32 are fastened together to form an outer ring chamber.

[0073] In some possible embodiments, the bottom of the inner ring burner seat 31 is provided with an airflow injection port, and at least one airflow communication channel 33 is provided between the inner ring burner seat 31 and the outer ring burner seat 32. When the bottom of the inner ring burner seat 31 is provided with an airflow injection port, and the airflow injection port is connected to the injection tube, the airflow in the burner is injected into the airflow injection port through the injection tube. Part of the gas is in the inner ring chamber, and the other part of the gas flows from the inner ring chamber to the outer ring chamber through the at least one airflow communication channel 33 provided between the inner ring burner seat 31 and the outer ring burner seat 32.

[0074] In some optional embodiments, the top surface of the outer ring flame cap 2 is a plane, and flame holes may be provided on the top and side surfaces of the outer ring flame cap 2.

[0075] In some other alternative embodiments, such as Figure 7-9As shown, the top surface of the outer ring burner cap 2 has a concave structure where the outer edge is higher than the inner edge, and flame holes can be provided on the side of the outer ring burner cap 2. In this way, the top surface of the outer ring burner cap 2 can become a concave reflective area, which can focus and reflect the heat from the bottom of the pot to a focal point (such as the central area of ​​the bottom of the pot) through the principle of focusing reflection, thereby effectively improving thermal efficiency.

[0076] Secondly, the concave structure can guide the soup and oil spills onto the top surface of the outer ring flame cap, so that the soup and oil are guided to the area without flame holes and are therefore less likely to clog the flame holes.

[0077] In some optional embodiments, a second support member including a first mounting hole 113 and a second mounting hole 114 can be disposed within the inner ring flame cap seat 31, thereby making it easier and faster to install the liquid holding device 12.

Furthermore, specific embodiments have been described above. Other embodiments are within the scope of the appended claims.
