Abstract
Description
Technical Field
[0001] This invention relates to the field of kitchen appliances technology, and more particularly to a stove. Background Technology
[0002] In current technology, most stoves use natural injection to mix air and gas. The amount of air injected is 60-70% of the air required for normal combustion. The remaining air needs to be replenished during combustion. The amount of replenishment is subject to the surrounding environment and cannot be controlled. This results in gas waste and reduced combustion efficiency of the stove. Summary of the Invention
[0003] The embodiments of the present invention provide a stove that solves the problem of reduced combustion efficiency in stoves.
[0004] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:
[0005] A stove includes a burner cap, a flame distributor, burner heads, an air intake, and an air distributor.
[0006] The igniter is connected to the flame cap, and a mixing chamber is formed between them. The flame cap has an outlet hole that communicates with the mixing chamber.
[0007] The burner head has a premixing chamber and a first air intake channel connected to the premixing chamber. The first air intake channel is used to introduce mixed gas into the premixing chamber. The burner head is connected to the burner distributor, and the premixing chamber is connected to the mixing chamber so that the mixed gas enters the mixing chamber from the premixing chamber.
[0008] The air intake component is connected to the burner head, and a second air intake channel is formed inside the air intake component, which connects to the outside and allows outside air to enter the second air intake channel.
[0009] The air distributor is connected to the burner head and the air intake. The air distributor contains a distribution chamber, a distribution orifice communicating with the distribution chamber, and a third air intake channel. The distribution orifice is located below the flame outlet. The second and third air intake channels communicate with each other, allowing external air to enter the distribution chamber through the second and third air intake channels and then exit through the distribution orifice below the flame outlet, thereby improving combustion efficiency.
[0010] Understandably, when the stove is working, the mixed gas enters the premixing chamber of the burner head through the first air intake channel. The mixed gas in the premixing chamber enters the mixing chamber and is burned through the flame outlet of the burner cap. At this time, the amount of secondary air is often insufficient to ensure complete combustion of the gas, and secondary air needs to be supplemented.
[0011] In the stove provided in this embodiment, external air enters the third air intake channel of the air distributor through the second air intake channel in the air intake component, and then enters the distribution chamber. The air in the distribution chamber is distributed and discharged below the flame outlet. In this way, the secondary air required for the combustion of the mixed gas at the flame outlet can be supplemented, thereby making the gas combustion more complete and improving the combustion efficiency of the stove.
[0012] As can be seen from the above, the stove provided in this application embodiment solves the problem of reduced combustion efficiency of the stove.
[0013] In some embodiments, the igniter includes a first connecting portion and an ignition portion. The first connecting portion is connected to the ignition portion and forms a gas supply channel. The ignition portion is connected to the burner cap and forms a mixing chamber. The gas supply channel communicates with the mixing chamber.
[0014] In some embodiments, the mixing chamber includes an inner mixing chamber and an outer mixing chamber;
[0015] The flame cap includes an inner ring flame cap and an outer ring flame cap, with the outer ring flame cap surrounding the inner ring flame cap.
[0016] The flame distribution section has a connecting channel, and the flame distribution section is connected to the inner ring flame cap to form an inner mixing chamber. The flame distribution section is connected to the outer ring flame cap to form an outer mixing chamber.
[0017] The gas delivery channel is connected to the inner mixing chamber, and the connecting channel connects the gas delivery channel and the outer mixing chamber.
[0018] In this way, the burner cap is divided into an inner ring burner cap and an outer ring burner cap. On the one hand, this can improve the heating effect of the stove on the pot, and on the other hand, the combustion efficiency of the stove can also be improved through the combustion of the double burner cap.
[0019] In some embodiments, the flame outlet includes an inner flame outlet and an outer flame outlet, with the inner flame outlet located on the inner ring flame cover and the outer flame outlet located on the outer ring flame cover.
[0020] In some embodiments, the inner flame outlet includes a plurality of first auxiliary flame outlets and a plurality of first main flame outlets spaced apart along the circumference of the inner ring flame cap. The first auxiliary flame outlets are located above the first main flame outlets. One end of the first main flame outlet is connected to the inner mixing chamber and the other end is connected to the outside. One end of the first auxiliary flame outlet is connected to the inner mixing chamber and the other end is connected to the outside.
[0021] In some embodiments, the outer flame port includes a plurality of second auxiliary flame ports and a plurality of second main flame ports arranged circumferentially along the outer ring flame cap, with the second main flame ports located above the second auxiliary flame ports; one end of the second main flame port is connected to the outer mixing chamber and the other end is connected to the outside; one end of the second auxiliary flame port is connected to the outer mixing chamber and the other end is connected to the outside.
[0022] It is understandable that setting auxiliary flame holes and main flame holes on the inner and outer ring burner caps respectively can improve the combustion efficiency of the stove. Specifically, when the stove is burning, the flame burning through the auxiliary flame holes can stabilize the flame burning through the main flame holes, thus improving the combustion efficiency of the stove.
[0023] In some embodiments, the dispensing hole includes a first dispensing hole and a second dispensing hole;
[0024] The air distributor includes a first annular wall and a second annular wall, with the second annular wall surrounding the first annular wall. A first distribution hole is located on the first annular wall, and a second distribution hole is located on the second annular wall. This allows air to exit from the first distribution hole to below the inner burner hole, and from the second distribution hole to below the outer burner hole, thereby improving combustion efficiency.
[0025] In some embodiments, there are multiple first distribution holes, which are spaced apart circumferentially along the first annular wall; there are also multiple second distribution holes, which are spaced apart circumferentially along the second annular wall. This increases the amount of air below the flare outlet, thereby improving combustion efficiency.
[0026] In some embodiments, the angle between the axial direction of the first distribution hole and the horizontal direction is greater than or equal to 0° and less than 90°; and / or, the angle between the axial direction of the second distribution hole and the horizontal direction is greater than or equal to 0° and less than 90°. This facilitates the discharge of air from the distribution cavity.
[0027] In some embodiments, the air distributor is provided with a second connecting portion, which is connected to an air intake component, and the second connecting portion is provided with a third air intake channel. This allows for a tighter connection between the air distributor and the air intake component, and facilitates the entry of outside air into the distribution chamber of the air distributor.

Detailed Implementation
[0046] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, when describing pipelines or channels, the terms "connection" and "linking" used in this application have the meaning of establishing electrical conductivity.

[0052] To achieve emission reduction goals, my country's main policy is to improve energy efficiency, expand renewable energy sources, and reduce coal consumption. Therefore, my country has raised the standards for the combustion efficiency of household stoves. However, most stoves currently use natural injection to mix air and gas, injecting only 60-70% of the required air volume for normal combustion. The remaining air needs to be replenished during combustion. This replenishment is subject to environmental constraints and cannot be controlled. This situation leads to gas waste and reduced stove combustion efficiency.
[0053] To address the aforementioned problems, embodiments of this application provide a stove, which refers to a kitchen appliance that uses gaseous fuels such as liquefied petroleum gas, manufactured gas, or natural gas for direct-fire heating. This application does not limit the specific gas supply method for the stove; for example, the stove can be a natural gas stove or a coal gas stove.
[0054] The stove of this application is described below with reference to the accompanying drawings.
[0055] like Figure 1 As shown, an embodiment of this application provides a stove, which includes a burner cap 1, a flame distributor 2, a burner head 3, an air intake component 4, and an air distributor 5. The burner head 3 has a premixing chamber (not shown in the figure) and a first air intake channel 30 communicating with the premixing chamber. The first air intake channel 30 is used to introduce mixed gas into the premixing chamber.
[0056] like Figure 2 , Figure 3 and Figure 4 As shown, the flame distributor 2 is connected to the flame cap 1, and a mixing chamber 20 is formed between them. The flame cap 1 is provided with a flame outlet 10 that communicates with the mixing chamber 20.
[0057] The burner head 3 is connected to the flame distributor 2, and the premixing chamber is connected to the mixing chamber 20, so that the mixed gas enters the mixing chamber 20 from the premixing chamber.
[0058] like Figure 5 and Figure 6 As shown, the air intake component 4 is connected to the burner head 3, and a second air intake channel 40 is formed inside the air intake component 4, which connects to the outside and allows outside air to enter the second air intake channel 40.
[0059] It should be understood that the air intake component 4 is provided with a first air intake 41 and a first air outlet 42. The first air intake 41 is connected to the second air intake channel 40, and the first air outlet 42 is connected to the second air intake channel 40.
[0060] Optionally, a small blower is typically connected to the first air inlet 41 to introduce external air into the second air inlet channel 40 through the first air inlet 41.
[0061] The air distributor 5 is connected to the burner head 3 and also to the air inlet component 4 (see reference). Figure 1 ).like Figure 7 As shown, the air distributor 5 has a distribution chamber 50 and a distribution hole 51 and a third air intake channel 52 communicating with the distribution chamber 50. The distribution hole 51 is located below the flame outlet 10. The second air intake channel 40 and the third air intake channel 52 communicate with each other so that external air enters the distribution chamber 50 through the second air intake channel 40 and the third air intake channel 52 and is discharged below the flame outlet 10 through the distribution hole 51, thereby improving combustion efficiency.
[0062] Understandably, when the stove is working, the mixed gas enters the premixing chamber of the burner head 3 through the first air intake channel 30. The mixed gas in the premixing chamber enters the mixing chamber 20 and is burned through the flame outlet 10 of the burner cap 1. At this time, the amount of secondary air is often insufficient to ensure complete combustion of the gas, and secondary air needs to be supplemented.
[0063] In the stove provided in this embodiment, external air enters the third air intake channel 52 of the air distributor 5 through the second air intake channel 40 in the air intake component 4, and then enters the distribution chamber 50. The air in the distribution chamber 50 is distributed and discharged below the flame outlet 10. In this way, the secondary air required for the combustion of the mixed gas at the flame outlet 10 can be supplemented, thereby making the gas combustion more complete and improving the combustion efficiency of the stove.
[0064] Based on this, such as Figure 8 As shown, the ignition distributor 2 includes a first connecting part 21 and an ignition part 22, with the first connecting part 21 connected to the ignition part 22.
[0065] like Figure 9 and Figure 10As shown, the first connecting part 21 and the ignition part 22 form a gas supply channel 23. The ignition part 22 is connected to the flame cap 1 and forms a mixing chamber 20. The gas supply channel 23 connects to the mixing chamber 20.
[0066] like Figure 11 As shown, the mixing chamber 20 includes an inner mixing chamber 200 and an outer mixing chamber 201. The flame cap 1 includes an inner ring flame cap 11 and an outer ring flame cap 12, with the outer ring flame cap 12 surrounding the inner ring flame cap 11.
[0067] The ignition section 22 has a connecting channel 220. The ignition section 22 is connected to the inner ring flame cap 11 and forms an inner mixing chamber 200. The ignition section 22 is connected to the outer ring flame cap 12 and forms an outer mixing chamber 201.
[0068] The gas delivery channel 23 is connected to the inner mixing chamber 200, and the connecting channel 220 connects the gas delivery channel 23 and the outer mixing chamber 201.
[0069] It is understandable that the connecting channel 220 formed in the burner section 22 will divert the mixed gas supplied by the burner head 3 to the burner 2 and allow it to enter the inner ring burner cap 11 and the outer ring burner cap 12 for combustion. This can improve the combustion efficiency of the stove and make the mixed gas burn more completely.
[0070] Compared to a single burner cap 1, the inner ring burner cap 11 and the outer ring burner cap 12 heat the cookware simultaneously, which makes the cookware heat more evenly and the heating area larger. This not only improves the performance of the cookware, but also improves the combustion efficiency of the stove.
[0071] Furthermore, such as Figure 12 As shown, the flame outlet 10 includes an inner flame outlet 110 and an outer flame outlet 120, with the inner flame outlet 110 located on the inner ring flame cover 11.
[0072] like Figure 13 As shown, the inner flame outlet 110 includes a plurality of first auxiliary flame outlets 111 and a plurality of first main flame outlets 112 arranged circumferentially along the inner ring flame cover 11. The first auxiliary flame outlets 111 are located below the first main flame outlets 112. One end of the first main flame outlet 112 is connected to the inner mixing chamber 200, and the other end is connected to the outside. One end of the first auxiliary flame outlet 111 is connected to the inner mixing chamber 200, and the other end is connected to the outside.
[0073] Optionally, the outer diameter of the inner ring flame cap 11 is 45mm, the diameter of the first auxiliary flame hole 111 is 2mm, and the inclination angle of the first auxiliary flame hole 111 can be 40°, that is, the angle between the central axis of the first auxiliary flame hole 111 and the first direction is 45°. Furthermore, 25 first auxiliary flame holes 111 can be evenly distributed around the outer circumference of the inner ring flame cap 11. The diameter of the first main flame hole 112 is 3mm, and the inclination angle of the first main flame hole 112 can be 40°, that is, the angle between the central axis of the first main flame hole 111 and the first direction is 45°. Figure 13 The included angle (in the X direction) is 45°, and 25 first main fire holes 112 can be evenly distributed around the outer periphery of the inner ring fire cover 11. This application does not make specific limitations on this.
[0074] An exit flame port 120 is provided on the outer ring flame cap 12. The exit flame port 120 includes a plurality of second auxiliary flame ports 121 and a plurality of second main flame ports 122 arranged circumferentially along the outer ring flame cap 12. The second main flame ports 122 are located above the second auxiliary flame ports 121. One end of the second main flame port 122 is connected to the outer mixing chamber 201, and the other end is connected to the outside. One end of the second auxiliary flame port 121 is connected to the outer mixing chamber 201, and the other end is connected to the outside.
[0075] Optionally, the outer diameter of the outer ring flame cap 12 is 100 mm, the diameter of the second auxiliary flame hole 121 is 1.1 mm, the inclination angle of the second auxiliary flame hole 121 can be 40°, and 59 second auxiliary flame holes 121 can be evenly distributed around the outer circumference of the outer ring flame cap 12. The diameter of the second main flame hole 122 is 3 mm, the inclination angle of the second main flame hole 122 can be 40°, and 59 second main flame holes 122 can be evenly distributed around the outer circumference of the outer ring flame cap 12. This application does not make specific limitations on this.
[0076] When the stove is burning, the flame burning through the auxiliary burner holes can stabilize the flame burning through the main burner holes, thus improving the stove's combustion efficiency.
[0077] It should be noted that the size of the flame outlet 10 can be adjusted appropriately according to the function (heat load, thermal efficiency) of the stove, and this application does not make specific limitations on this.
[0078] In some embodiments, such as Figure 14 As shown, the dispensing hole 51 includes a first dispensing hole 51 and a second dispensing hole 51.
[0079] The air distributor 5 includes a first annular wall 53 and a second annular wall 54, with the second annular wall 54 surrounding the first annular wall 53. A first distribution hole 51 is located on the first annular wall 53, and a second distribution hole 51 is located on the second annular wall 54. In this way, air is discharged from the first distribution hole 51 to below the inner burner hole 10, and from the second distribution hole 51 to below the outer burner hole 10, thereby improving combustion efficiency.
[0080] Based on this, multiple first distribution holes 51 are provided, and these multiple first distribution holes 51 are spaced apart circumferentially along the first annular wall 53. Multiple second distribution holes 51 are also provided, and these multiple second distribution holes 51 are spaced apart circumferentially along the second annular wall 54. This increases the amount of air below the flame outlet 10, thereby improving combustion efficiency.
[0081] Furthermore, the angle between the axial direction of the first distribution hole 51 and the horizontal direction is greater than or equal to 0° and less than 90°; and / or, the angle between the axial direction of the second distribution hole 51 and the horizontal direction is greater than or equal to 0° and less than 90°. This facilitates the discharge of air from the distribution cavity 50.
[0082] Optionally, the angle between the axial direction and the horizontal direction of the first distributing hole 51 can be 45°, and the angle between the axial direction and the horizontal direction of the second distributing hole 51 can be 45°. This application does not specifically limit this.
[0083] In some embodiments, such as Figure 14 and Figure 15 As shown, the air distributor 5 is also provided with a second connecting part 55, which is connected to the air intake 4, and the second connecting part 55 is provided with a third air intake channel 52.
[0084] It is understood that the second connecting part 55 is located on the two sides of the second annular wall 54 away from the second annular wall 54, and the second connecting part 55 is provided with a second air inlet 550 and a second air outlet 551. The second air inlet 550 is connected to the third air inlet channel 52, and the second air inlet 550 is located on the side of the connecting part adjacent to the burner head 3. The second air outlet 551 is connected to the third air inlet channel 52, and the second air outlet 551 is located on the circumferential surface of the first annular wall 53.
[0085] This facilitates the connection between the air intake 4 and the air distributor 5, and also allows external air to enter the distribution chamber 50 of the air distributor 5.
[0086] In some embodiments, such as Figure 16As shown, the first connecting part 21 of the burner 2 is provided with a heat insulation cavity 210. The heat insulation cavity 210 contains air or mixed gas (as is common knowledge, the heat transfer efficiency of air or mixed gas is low). Therefore, the heat insulation cavity 210 can reduce the heat transfer efficiency between the burner 22 and the first connecting part 21 and between the first connecting part 21 and the burner head 3, thereby reducing the heat transferred from the burner 22 to the first connecting part 21 and from the first connecting part 21 to the burner head 3.
[0087] In this way, less heat is lost after the mixed gas is burned, and consequently, more heat is transferred to the cookware, thereby improving the combustion efficiency of the stove and solving the problem of low combustion efficiency in related technologies.
[0088] Based on this, the heat insulation cavity 210 is arranged around the gas transmission channel 23 to increase the volume of the heat insulation cavity 210, thereby increasing the heat insulation effect of the heat insulation cavity 210.
[0089] It is understandable that the gas supply channel 23 is connected to the first air intake channel 30, meaning that the gas supply channel 23 is close to the burner head 3. The heat generated by the combustion of the mixed gas is easily transferred to the burner head 3 through the gas supply channel 23, so a lot of heat is lost through the gas supply channel 23.
[0090] Furthermore, the heat insulation cavity 210 is set around the gas supply channel 23. On the one hand, it can insulate the parts that are prone to heat loss and where a lot of heat loss occurs, thus making the heat insulation cavity 210 more effective. On the other hand, the increased volume of the heat insulation cavity 210 increases the capacity of the air or mixed gas it can hold. The increased capacity of the heat insulation cavity 210 results in stronger heat insulation, which reduces heat loss and thus improves the combustion efficiency of the stove.
[0091] Furthermore, the heat insulation cavity 210 includes a first cavity 211 and a second cavity 222. The first cavity 211 is located below the second cavity 222. The first cavity 211 is disposed near the burner head 3, and the second cavity 222 is disposed near the fire distribution section 22.
[0092] It is understandable that the gas supply channel 23 is more likely to transfer heat to the burner 3 at the locations near the burner head 3 and near the fire distribution section 22; that is, these two locations are where heat can be easily transferred between the gas supply channel 23 and the burner head 3. Providing the insulation cavity 210 at these two locations can improve the insulation effect of the insulation cavity 210.
[0093] The gas supply channel 23, located near the burner 3 and near the flame distribution section 22, which are the two locations most prone to heat loss, has a heat insulation cavity 210. This reduces heat loss at these two locations, resulting in less heat loss from the stove. Consequently, more heat is transferred to the cookware, thus improving the stove's combustion efficiency.
