Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of household appliances, in particular to a stove. BACKGROUND

[0002] The stove is a kind of device for cooking food materials commonly used in household kitchens and commercial kitchens, and as people's requirements for life quality are getting higher and higher, people's requirements for the stove are also improving.

[0003] The burner is the most important structure in the stove, compared with the side injection burner used in the traditional stove, the flat plate burner is a kind of modern burner, which has the characteristics of uniform heating and direct injection, can effectively improve the heating uniformity, and improve the combustion thermal efficiency, so it is more and more used in the stove.

[0004] However, since the fire hole of the flat plate burner is located on the upper surface of the fire cover, and has multiple circles of fire holes, the air-fuel mixture is difficult to uniformly diffuse to all parts of the fire cover in the small buffering space inside the burner, thereby causing uneven flame combustion, resulting in reduced combustion performance, and seriously affecting the cooking experience. CONTENT OF THE INVENTION

[0005] The embodiment of the present application provides a kind of stove, air-fuel mixture can be uniformly dispersed to each area of burner, make combustion more uniform, thereby improving user experience.

[0006] In a first aspect, the embodiment of the present application provides a kind of stove, comprising:

[0007] Panel, panel is opened with cooking eye;

[0008] Bottom shell, bottom shell is installed below panel, and with panel to form installation cavity;

[0009] Flat plate burner, flat plate burner is installed in installation cavity, and flat plate burner part penetrates cooking eye, and protrudes panel setting;

[0010] The flat plate burner comprises:

[0011] Burner, burner is arranged in installation cavity, for the input of gas;

[0012] Distributor, distributor is arranged on burner, and located in cooking eye, distributor is structured with:

[0013] Mixing chamber, mixing chamber is communicated with burner;

[0014] Inner air duct, inner air duct is communicated with mixing chamber;

[0015] At least two outer air ducts, at least two outer air ducts are respectively communicated with mixing chamber, and at least two outer air ducts are arranged around inner air duct;

[0016] An outer fire cover is arranged on the top of the fire divider and forms an outer uniform fire chamber with the fire divider, and at least two outer air passages are respectively communicated with the outer uniform fire chamber;

[0017] A uniform fire plate is arranged in the outer uniform fire chamber and above the outer air passages;

[0018] An inner fire cover is arranged on the top of the fire divider and forms an inner uniform fire chamber with the fire divider, and an inner air passage is communicated with the inner uniform fire chamber;

[0019] The uniform fire plate is provided with a plurality of honeycomb holes, and the honeycomb holes are opposite to the outer air passages.

[0020] In this way, by designing the fire divider on the stove head, the gas and air can be fully mixed in the mixing chamber, the inner air passage and the outer air passage, and further mixed through the inner and outer uniform fire chambers formed between the fire divider and the inner and outer fire covers. By arranging the honeycomb holes on the uniform fire plate, the honeycomb holes are opposite to the outer air passages, so that the mixed gas entering the outer uniform fire chamber from the outer air passages can slow down the gas flow rate under the blocking action of the honeycomb holes, so that the gas and air can be uniformly distributed in each area of the outer uniform fire chamber, and the combustion is more uniform. At the same time, the honeycomb holes slow down the gas flow rate, which helps to maintain the stability of the flame on the outer fire cover and prevent the flame from being unstable or extinguished due to too fast gas flow. Uniformly distributed gas and stable flame help to improve combustion efficiency, ensure full combustion of gas, reduce energy waste, and reduce use cost. Moreover, the design of the honeycomb holes can reduce the noise generated during gas flow, making the stove more quiet during use and improving user experience. Uniform heat distribution can also reduce the local high temperature pressure of the fire cover, reduce the thermal fatigue and loss of the material, and prolong the service life of the fire cover.

[0021] In some embodiments of the present application, the opening of the outer air passage gradually increases from the mixing chamber to the outer uniform fire chamber.

[0022] In this way, the gradually increasing opening design can effectively reduce the gas flow rate, which helps to gradually slow down the speed of the air and gas before they enter the outer uniform fire chamber, thereby avoiding the phenomenon of unstable or uneven flame caused by too fast gas flow, ensuring that the mixed gas of air and gas can be more uniformly distributed to each area of the outer fire cover, achieving more uniform flame distribution, ensuring uniform heating of the pot, and improving cooking effect.

[0023] In some embodiments of the present application, the outer fire cover comprises:

[0024] An outer side wall in the form of a ring;

[0025] An inner side wall in the form of a ring, the inner side wall is located inside the ring of the outer side wall, and is arranged along the radial direction of the ring and spaced apart from the outer side wall;

[0026] An outer top wall connects the top of the outer side wall and the top of the inner side wall, and a plurality of outer fire holes are provided on the outer top wall;

[0027] A distributor is connected to the bottom of the inner side wall and the bottom of the outer side wall, and the outer side wall, the outer top wall, the inner side wall, and the distributor form an outer uniform combustion chamber.

[0028] In this way, the outer side wall, the inner side wall, and the outer top wall of the outer fire cover form a closed outer uniform combustion chamber, ensuring that the gas has sufficient time and space to mix thoroughly before entering the outer fire holes, and can be evenly distributed in the outer uniform combustion chamber, helping to achieve more uniform flame distribution, ensuring uniform heating of the cookware and improving cooking performance. By controlling the flow of gas in the outer uniform combustion chamber, the design of the outer fire cover helps to maintain the stability of the flame, reduces the risk of the flame being extinguished due to uneven airflow, and improves the safety of the stove. The plurality of outer fire holes on the outer top wall allows users to better control the size and distribution of the fire, adapting to different cooking needs and providing precise control over heat.

[0029] In some embodiments of the present application, the distributor includes an annular inner sealing wall;

[0030] In the height direction of the stove, the inner sealing wall is opposite to the inner side wall, and the side of the inner side wall facing the distributor is provided with a sealing groove, which is in communication with the outer uniform combustion chamber, and the inner sealing wall is arranged in the sealing groove.

[0031] In this way, the combination of the inner sealing wall and the sealing groove provides an additional stepped sealing surface to prevent gas leakage and ensure that the gas is effectively controlled and guided when entering the outer uniform combustion chamber, improving the safety of the stove. By moving the sealing step surface to the outside of the distributor, the effective area of the upper surface of the outer fire cover is expanded, and an additional ring of fire holes can be provided on the outer fire cover, thereby increasing the coverage of the flame. Increasing the number and distribution area of the fire holes helps to reduce the burning heat intensity of each fire hole, reduces the risk of local overheating, achieves more uniform heat distribution, and improves overall combustion performance.

[0032] In some embodiments of the present application, a chamfer surface is provided at the connection between the outer top wall and the outer side wall, and a plurality of side fire holes are provided on the chamfer surface.

[0033] In this way, the side fire holes on the chamfer surface increase the directionality and coverage of the flame, allowing heat to be more evenly distributed to the cookware, thereby improving the uniformity and efficiency of cooking. The design of the side fire holes allows better air flow and gas mixing, improving combustion efficiency.

[0034] In some embodiments of the present application, a plurality of rings of outer fire holes are provided around the inner fire cover, and the side fire holes are arranged in intervals with the outermost ring of outer fire holes along the circumference of the outer fire cover.

[0035] In this way, the design of multiple outer fire holes ensures that the flame can uniformly cover the pot, providing more uniform heat distribution, helping to improve cooking effect and reduce the problem of local overheating or uneven heating. By setting the side fire holes and the outermost circle of outer fire holes at intervals in the circumferential direction of the outer fire cover, the coverage range and directionality of the flame are optimized, which helps to uniformly heat and improve thermal efficiency, making the cooking process more efficient.

[0036] In some embodiments of the present application, the diameter of the side fire hole is smaller than the diameter of the outer fire hole.

[0037] In this way, the small-diameter side fire hole can produce more concentrated flame, helping to more effectively transfer heat to the pot and improve thermal efficiency and reduce heat loss. By optimizing the size of the fire hole, the mixing efficiency of gas and air is improved, and the smaller side fire hole helps to maintain the stability of the flame and reduce the risk of flame extinguishing due to uneven airflow or external interference, improving the reliability and safety of the stove.

[0038] In some embodiments of the present application, the inner fire cover includes a thickening area and an edge area connected thereto, and a plurality of inner fire holes are arranged on the thickening area and the edge area, and the edge area surrounds the thickening area, and the thickening area is opposite to the inner air duct.

[0039] In this way, the design of the thickening area increases the overall structural strength of the inner fire cover, making it more durable and better able to withstand high temperatures and mechanical stress. The position of the thickening area opposite to the inner air duct helps to optimize heat conduction. The thickening area can more effectively absorb and distribute heat, ensuring uniform temperature of the fire cover and helping to improve combustion efficiency.

[0040] In some embodiments of the present application, the thickness of the thickening area is greater than the thickness of the edge area.

[0041] In this way, by making the thickness of the thickening area greater than that of the edge area, the thickness of the inner fire cover area above the inner air duct is increased, effectively slowing down the flow rate of the air-fuel mixture, helping to prevent the flame from separating from the fire hole on the inner fire cover and improving the stability and safety of combustion. At the same time, the slowed flow rate allows the air-fuel mixture to have more time to mix before entering the inner fire hole, thereby improving combustion efficiency.

[0042] In some embodiments of the present application, the inner fire hole is arranged vertically to the surface of the area where it is located; the surface of the thickening area is parallel to the panel; and in the direction from the thickening area to the edge area, the top surface of the edge area is gradually inclined towards the direction of the fire divider.

[0043] In this way, by opening the internal flame holes perpendicular to the surface of the area, the design of the internal flame holes helps optimize the mixing efficiency of gas and air, ensuring complete combustion. The design of the thickened area and the sloping edge area helps guide the flame to be evenly distributed to the cookware, reducing flame spread and flame lift-off, and improving combustion stability and safety.

[0067] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0068] The stove is a kind of device commonly used in household kitchen and commercial kitchen to cook food materials. With the increasing demand for life quality, people's requirements for the stove are also increasing.

[0069] The burner is the most important structure in the stove. Compared with the side injection burner used in the traditional stove, the flat plate burner is a kind of modern burner, which has the characteristics of uniform heating and direct injection, can effectively improve the uniformity of heating, and improve the combustion efficiency, so it is more and more used in the stove.

[0070] However, since the fire hole of the flat plate burner is located on the upper surface of the fire cover, and has multiple circles of fire holes, the air-fuel mixture has a small buffer space inside the burner, and it is difficult to uniformly diffuse to all parts of the fire cover, resulting in uneven flame combustion, which reduces the combustion performance and seriously affects the cooking experience.

[0071] Through repeated thinking and verification, the inventor found that if a uniform fire plate is arranged between the fire divider and the fire cover, the honeycomb holes are arranged on the uniform fire plate, the honeycomb hole area of the uniform fire plate is opposite to the air outlet channel on the fire divider, the flow rate of the gas entering the fire cover from the air outlet channel is reduced by the blocking effect of the honeycomb holes, the flame can be evenly distributed to each area of the fire cover, the combustion is more uniform, and the user experience is improved.

[0072] Figure 1 A structural schematic diagram of a stove provided by an embodiment of the present application is shown.

[0073] As shown in Figure 1 The stove 200 provided by the embodiment of the present application includes a panel 201, a bottom shell 202, and a flat plate burner 100. The panel 201 is provided with a cooking eye. The bottom shell 202 is installed below the panel 201 and surrounds the panel 201 to form an installation cavity. The flat plate burner 100 is installed in the installation cavity, and part of the flat plate burner 100 protrudes out of the cooking eye and protrudes from the panel 201. The flat plate burner 100 is used for a user to perform various cooking operations.

[0074] The stove 200 is also provided with a gas pipeline, which is in communication with the flat plate burner 100 and is used to provide gas for the flat plate burner 100, so that the flat plate burner 100 can burn conveniently.

[0075] In some embodiments of the present application, two cooking eyes are arranged on the panel 201.

[0076] Figure 2 A structural schematic diagram of a flat plate burner of a stove is shown. Figure 1 A structural schematic diagram of a flat plate burner of a stove is shown. Figure 3 A structural schematic diagram of a flat plate burner of a stove is shown. Figure 1 A structural schematic diagram of a flat plate burner of a stove is shown. Figure 4 A structural schematic diagram of a flat plate burner of a stove is shown. Figure 2 A structural schematic diagram of a flat plate burner of a stove is shown.

[0077] As shown in Figure 2 and Figure 3As shown, the flat burner 100 comprises a burner head 10, a burner distributor 20, an outer burner cap 30, a uniform burner plate 40 and an inner burner cap 50. The burner head 10 is arranged in the mounting cavity. The burner head 10 is in communication with the gas pipeline for the input of gas. The burner distributor 20 is arranged on the burner head 10 and located in the cooking zone. The outer burner cap 30, the uniform burner plate 40 and the inner burner cap 50 are arranged on the burner distributor 20 respectively. The burner distributor 20 is used to distribute the mixture of gas and air evenly to each part of the burner. The outer burner cap 30 is located in the outer periphery and the inner burner cap 50 is located in the central area. The outer burner cap 30 and the inner burner cap 50 have a plurality of burner holes respectively through which the gas is ignited to form the flame. The uniform burner plate 40 is located between the outer burner cap 30 and the burner distributor 20 for further homogenization and dispersion of the air-fuel mixture between the outer burner cap 30 and the burner distributor 20.

[0078] The burner distributor 20 is configured with a mixing cavity 21, an inner gas channel 22 and at least two outer gas channels 23. The mixing cavity 21 is in communication with the burner head 10, and the inner gas channel 22 and the at least two outer gas channels 23 are in communication with the mixing cavity 21 respectively. The at least two outer gas channels 23 are arranged around the inner gas channel 22 on the burner distributor 20. The mixing cavity 21 is the primary mixing area of the gas and air. It is in communication with the burner head 10 to receive the gas and air delivered from the burner head 10, and in the mixing cavity 21, the two gases begin to mix to provide the appropriate gas-air ratio for subsequent combustion. The inner gas channel 22 is responsible for delivering the air-fuel mixture in the mixing cavity 21 to the central area of the burner distributor 20. The outer gas channels 23 are arranged around the inner gas channel 22 for delivering the air-fuel mixture in the mixing cavity 21 to the peripheral area of the burner distributor 20. The outer gas channels 23 are used to ensure that the flame can uniformly cover a larger heating area. Through the design of surrounding the inner gas channel 22, the outer gas channels 23 help to form the peripheral flame and enhance the uniformity of the overall heat distribution.

[0079] In some embodiments of the present application, in order to improve the processing convenience of the flat burner 100 and reduce the cost, the flat burner 100 adopts the parallel double-ejector pipe burner head of the conventional side-injection burner and the radiation-distributed three-channel gas path distributor.

[0080] As shown in FIG. 1, Figure 10 The outer burner cap 30 is arranged on the top of the burner distributor 20 and forms an annular outer uniform burner cavity 31 with the burner distributor 20, and the at least two outer gas channels 23 are in communication with the outer uniform burner cavity 31 respectively. The outer uniform burner cavity 31 is an annular cavity formed by the space between the outer burner cap 30 and the burner distributor 20. The main function of the outer uniform burner cavity 31 is to uniformly distribute the air-fuel mixture delivered from the outer gas channels 23. By uniformly distributing the gas in the outer uniform burner cavity 31, it is ensured that the flame can be uniformly ejected from the burner holes of the outer burner cap 30, thereby providing a uniform heating effect.

[0081] As shown in FIG. 1, Figure 4As shown, the fire plate 40 is arranged in the outer fire cavity 31 and above the outer air passage 23. The fire plate 40 is provided with a plurality of honeycomb holes 41, which are opposite to the outer air passage 23.

[0082] Since the fire holes of the flat burner 100 are located on the upper surface of the fire cap, the buffering space of the air-fuel mixture in the outer fire cavity 31 is small, so the fire plate 40 is designed. The fire plate 40 can further homogenize the flow and distribution of the air-fuel mixture in the outer fire cavity 31. By arranging the fire plate 40 in the outer fire cavity 31, the flow rate of the gas entering the outer fire cavity 31 from the outer air passage 23 can be slowed down, and the stability of the gas flow can be increased, thereby ensuring the uniformity and stability of the flame on the outer fire cap 30. The plurality of honeycomb holes 41 on the fire plate 40 are opposite to the outer air passage 23, which helps to refine the gas flow, so that the air-fuel mixture can be more evenly distributed when passing through the fire plate 40.

[0083] The inner fire cap 50 is arranged at the top of the fire divider 20 and forms an inner fire cavity 51 with the fire divider 20. The inner air passage 22 communicates with the inner fire cavity 51. The inner fire cavity 51 is a cavity formed by the space between the inner fire cap 50 and the fire divider 20. The main function of the inner fire cavity 51 is to uniformly distribute the air-fuel mixture delivered from the inner air passage 22. By uniformly distributing the gas in the inner fire cavity 51, it ensures that the flame can be uniformly sprayed from the fire holes of the inner fire cap 50, thereby providing concentrated heating effect. The inner air passage 22 is responsible for delivering the air-fuel mixture in the mixing chamber 21 to the inner fire cavity 51. Through the communication with the inner fire cavity 51, the inner air passage 22 ensures that the mixed gas can be evenly distributed in the entire inner fire cavity 51, thereby forming a stable central flame, improving the combustion efficiency and the concentration of heat.

[0084] Thus, by designing the gas distributor 20 on the burner head 10, the gas and air can be fully mixed in the mixing chamber 21, the inner air channel 22, and the outer air channel 23, and further mixed through the inner and outer uniform combustion chambers formed between the gas distributor 20 and the inner and outer fire caps 50 and 30. By arranging the honeycomb holes 41 on the uniform fire plate 40, the honeycomb holes 41 are opposite to the outer air channel 23, so that the mixed gas entering the outer uniform combustion chamber 31 from the outer air channel 23 can slow down the gas flow rate into the outer uniform combustion chamber 31 under the blocking effect of the honeycomb holes 41, so that the gas and air can be uniformly distributed in each area of the outer uniform combustion chamber 31, making the combustion more uniform. At the same time, slowing down the gas flow rate through the honeycomb holes 41 helps to maintain the stability of the flame on the outer fire cap 30, preventing the flame from being unstable or extinguished due to too fast gas flow. Uniformly distributed gas and stable flame help to improve combustion efficiency, ensure that the gas can be fully burned, reduce energy waste, and reduce use cost. Moreover, the design of the honeycomb holes 41 can reduce the noise generated when the gas flows, making the cooktop 200 more quiet during use and improving user experience. Uniform heat distribution also reduces the local high temperature pressure of the fire cap, reduces the thermal fatigue and loss of the material, thereby prolonging the service life of the fire cap.

[0085] Figure 5 For Figure 2 the structure of the gas distributor of the flat burner shown in FIG. 1. Figure 6 For Figure 2 the structure of the gas distributor of the flat burner shown in FIG. 1.

[0086] As Figure 5 and Figure 6 shown, in some embodiments of the present application, the opening of the outer air channel 23 gradually increases from the mixing chamber 21 to the outer uniform combustion chamber 31. As the opening of the outer air channel 23 gradually increases, the speed of gas flow will slow down, which helps to reduce the degree of turbulence of gas flow, so that the air-gas mixture can enter the outer uniform combustion chamber 31 more smoothly.

[0087] Thus, the gradually increasing opening design can effectively reduce the gas flow rate, which helps to gradually slow down the speed of air and gas before they enter the outer uniform combustion chamber 31, thereby avoiding the phenomenon of unstable or uneven flame caused by too fast gas flow, ensuring that the air-gas mixture can be more uniformly distributed to each area of the outer fire cap 30, achieving more uniform flame distribution, ensuring uniform heating of the pot, and improving cooking effect.

[0088] In some embodiments of the present application, the gas distributor 20 is provided with three outer air channels 23. The three outer air channels 23 are uniformly arranged around the inner air channel 22 on the gas distributor 20.

[0089] In some embodiments of this application, the external air passage 23 is funnel-shaped, with a small central area and a large peripheral area, thereby slowing down the flow rate of gas as it passes through the external air passage 23, which is beneficial for its dispersion in all directions.

[0090] Figure 7 for Figure 2 One of the schematic diagrams of the outer flame cap of the flat plate burner shown. Figure 8 for Figure 2 The second schematic diagram of the outer flame cap of the flat plate burner is shown.

[0091] like Figure 7 and Figure 8 As shown, in some embodiments of this application, the outer flame cap 30 includes an outer side wall 32, an inner side wall 33, and an outer top wall 34. The outer side wall 32 is annular. The inner side wall 33 is annular and located inside the annulus of the outer side wall 32, and is radially spaced from the outer side wall 32. The outer top wall 34 connects the top of the outer side wall 32 and the top of the inner side wall 33, and has a plurality of outer flame holes 341. The flame spreader 20 is connected to the bottom of the inner side wall 33 and the bottom of the outer side wall 32, and an outer flame distribution chamber 31 is formed between the outer side wall 32, the outer top wall 34, the inner side wall 33, and the flame spreader 20. The outer side wall 32 is the outer periphery of the outer flame cap 30, helping to define the outer boundary of the outer flame distribution chamber 31, and is used to control the outward expansion of the flame on the outer flame cap 30, ensuring that the flame burns within a predetermined range. The inner wall 33 is located inside the outer flame cap 30, helping to define the inner boundary of the outer flame distribution chamber 31. The inner wall 33 and the outer wall 32 work together to ensure the uniform distribution of flame within the outer flame distribution chamber 31. The outer top wall 34 connects the outer wall 32 and the inner wall 33, and has multiple outer flame holes 341 on it. The main function of the outer top wall 34 is to provide a channel for the gas to be ejected. Through these outer flame holes 341, the gas is ignited to form a flame.

[0092] In this way, the outer side wall 32, inner side wall 33, and outer top wall 34 of the outer burner cap 30 form a closed outer uniform flame chamber 31. This ensures that the gas has sufficient time and space to mix thoroughly before entering the outer flame holes 341, allowing for even distribution within the outer uniform flame chamber 31. This contributes to a more uniform flame distribution, ensuring even heating of the cookware and improving cooking results. By controlling the flow of gas within the outer uniform flame chamber 31, the outer burner cap 30 design helps maintain flame stability, reducing the risk of flame extinguishing due to uneven airflow and improving cookware safety. The multiple outer flame holes 341 on the outer top wall 34 allow users to better control the size and distribution of the heat, adapting to different cooking needs and providing precise heat control.

[0093] Figure 9 for Figure 2 The image shows a cross-sectional view of a flat-plate burner. Figure 10 for Figure 9An enlarged structural schematic view of the connection between the fire divider and the outer fire cover in the flat burner shown.

[0094] As shown in Figure 9 and Figure 10 In some embodiments of the present application, the fire divider 20 includes an inner sealing wall 24, which is annular. Along the height direction of the cooktop 200, the inner sealing wall 24 is opposite to the inner side wall 33, which is provided with a sealing groove 331 on the side facing the fire divider 20, and the sealing groove 331 is in communication with the outer uniform combustion chamber 31. The inner sealing wall 24 is arranged in the sealing groove 331. The inner sealing wall 24 is used to isolate and seal the outer uniform combustion chamber 31, to ensure that the air-fuel mixture flows in the predetermined outer uniform combustion chamber 31, and to prevent leakage or unnecessary mixing. The inner side wall 33 is opposite to the inner sealing wall 24 and cooperates with the inner sealing wall 24 to ensure the path of gas flow. The sealing groove 331 is used to accommodate the inner sealing wall 24, forming a sealed passage to seal the outer uniform combustion chamber 31.

[0095] In this way, the combination of the inner sealing wall 24 and the sealing groove 331 provides an additional stepped sealing surface to prevent gas leakage and ensure that the gas is effectively controlled and guided when entering the outer uniform combustion chamber 31, thereby improving the safety of the cooktop 200.

[0096] Moreover, since the sealing groove 331 is in communication with the outer uniform combustion chamber 31, i.e., the sealing groove 331 is arranged on the side of the inner side wall 33 close to the outer side wall 32, the stepped sealing surface formed by the inner sealing wall 24 and the sealing groove 331 is moved to the outside of the fire divider 20, and the effective area of the upper surface of the outer fire cover 30, i.e., the outer top wall 34, is expanded. The width of the outer uniform combustion chamber 31 in the outer fire cover 30 can be designed to be wider, and an additional ring of outer fire holes 341 can be provided on the outer fire cover 30, thereby increasing the coverage range of the flame. Increasing the number and distribution area of the outer fire holes 341 helps to reduce the combustion heat intensity of each outer fire hole 341, reduces the risk of local overheating, achieves more uniform heat distribution, and improves the overall combustion performance.

[0097] In some embodiments of the present application, a chamfer surface 35 is arranged at the connection between the outer top wall 34 and the outer side wall 32, and a plurality of side fire holes 351 are arranged on the chamfer surface 35. The side fire holes 351 are located on the chamfer surface 35 and are responsible for injecting air-fuel mixture and forming flames. The design of the side fire holes 351 allows the flames to be ejected at a certain angle, covering a larger heating area.

[0098] In this way, the side fire holes 351 on the chamfer surface 35 increase the directionality and coverage range of the flames, allowing the heat to be more evenly distributed to the cookware, thereby improving the uniformity and efficiency of cooking. The design of the side fire holes 351 allows better air flow and gas mixing, improving the combustion efficiency.

[0099] In some embodiments of the present application, the outer fire holes 341 are arranged in multiple rings around the inner fire cover 50, and the side fire holes 351 are arranged in the circumferential direction of the outer fire cover 30 and spaced apart from the outermost ring of outer fire holes 341.

[0100] In this way, the design of multiple rings of outer fire holes 341 allows the outer fire cover 30 to generate flames in different areas, thereby covering a larger heating area, ensuring that the flames can uniformly cover the cookware, providing more uniform heat distribution, helping to improve cooking results and reduce the problem of local overheating or uneven heating. By spacing the side fire holes 351 from the outermost ring of outer fire holes 341 in the circumferential direction of the outer fire cover 30, the coverage and directionality of the flame are optimized, helping to achieve uniform heating, improve thermal efficiency, and make the cooking process more efficient.

[0101] In some embodiments of the present application, the diameter of the side fire holes 351 is smaller than the diameter of the outer fire holes 341.

[0102] In this way, the small-diameter side fire holes 351 can produce more concentrated flames, helping to more effectively transfer heat to the cookware, helping to improve thermal efficiency and reduce heat loss. By optimizing the size of the fire holes, the mixing efficiency of gas and air is improved, and the smaller side fire holes 351 help to maintain the stability of the flame, reducing the risk of flame extinguishing due to uneven airflow or external interference, improving the reliability and safety of the cooktop.

[0103] In some embodiments of the present application, the outer fire cover 30 is designed with six rings of fire holes, five of which are located on the upper surface (i.e., the outer top wall 34) of the outer fire cover 30, which are outer fire holes 341. The outer fire holes 341 are vertically upwardly open, and the diameter of the outer fire holes 341 is 2mm. The number of outer fire holes 341 in each ring from inside to outside is 78, 84, 90, 96, and 102. A ring of side fire holes 351 is arranged outside the outer fire holes 341. The angle between the side fire holes 351 and the horizontal plane is 75°, the number of side fire holes 351 is 102, and the diameter of the side fire holes 351 is 1.8mm. The side fire holes 351 are spaced apart from the outermost outer fire holes 341.

[0104] Figure 11 For Figure 2 the structure diagram of the uniform fire plate of the flat burner shown in the figure.

[0105] Please also refer to Figure 11 In some embodiments of the present application, the fire divider 20 is provided with a positioning column 25. The outer fire cover 30 is provided with a positioning groove 36. The positioning groove 36 is located in the outer uniform fire chamber 31. The uniform fire plate 40 is provided with a positioning hole 42. The positioning column 25, the positioning groove 36 and the positioning hole 42 are arranged opposite to each other. By means of screws, bolts and the like passing through the positioning column 25 and the positioning hole 42 and being fixed in the positioning groove 36, the fire divider 20, the outer fire cover 30 and the uniform fire plate 40 are tightly connected.

[0106] In some embodiments of the present application, three positioning columns 25, three positioning grooves 36 and three positioning holes 42 are respectively arranged, so as to improve the stability of the connection.

[0107] In some embodiments of the present application, in order to improve the fool-proof effect of the flat burner 100 and avoid user error placement, the positioning columns 25, the positioning grooves 36 and the positioning holes 42 are unevenly distributed on the distributor 20, the outer fire cover 30 and the fire plate 40.

[0108] Figure 12 For Figure 2 Structure diagram of the inner fire cover of the flat burner. Figure 13 For Figure 2 Structure diagram of the inner fire cover of the flat burner. Figure 14 For Figure 12 Cross-sectional view of the inner fire cover. In some embodiments of the present application, the distributor 20, the outer fire cover 30 and the fire plate 40 are connected by screws.

[0109] As Figure 12 and Figure 13 In some embodiments of the present application, the inner fire cover 50 includes an inner top wall 52. The inner top wall 52 is provided with a thickened area 521 and an edge area 522 connected thereto. A plurality of inner fire holes 523 are arranged on the thickened area 521 and the edge area 522. The edge area 522 surrounds the thickened area 521, and the thickened area 521 is opposite to the inner air duct 22. The thickened area 521 opposite to the inner air duct 22 is the main injection area of the air-fuel mixture. The design of the edge area 522 helps to expand the heating range and provide more uniform heat distribution. Through the flame surrounding the thickened area 521, the edge area 522 can ensure the overall heating of the bottom of the pot, reduce cold spots and improve the uniformity of cooking.

[0110] In this way, the design of the thickened area 521 increases the overall structural strength of the inner fire cover 50, making it more durable and better able to withstand high temperatures and mechanical stress. The position of the thickened area 521 opposite to the inner air duct 22 helps to optimize heat conduction. The thickened area 521 can more effectively absorb and distribute heat, ensuring uniform temperature of the inner fire cover 50 and helping to improve combustion efficiency.

[0111] As Figure 14 shown, in some embodiments of the present application, the thickness of the thickened area 521 is greater than the thickness of the edge area 522.

[0112] In this way, by increasing the thickness of the thickened area 521 greater than the edge area 522, the thickness of the inner fire cover 50 area above the inner air channel 22 is increased, effectively slowing down the flow rate of the air-fuel mixture, helping to prevent the flame from the inner fire cover 50 from the flame hole, improving the stability and safety of combustion. At the same time, the slowed flow rate allows the air-fuel mixture to have more time to mix before entering the inner flame hole 523, thereby improving combustion efficiency.

[0113] In some embodiments of the present application, the thickness of the thickened area 521 is 2mm thicker than the thickness of the edge area 522.

[0114] In some embodiments of the present application, the inner flame hole 523 is vertically upward with respect to the surface of the area where it is located. The surface of the thickened area 521 is parallel to the panel 201, that is, the inner flame hole 523 on the thickened area 521 is vertically upward. The flame of the thickened area 521 provides concentrated and intense heating. In the direction from the thickened area 521 to the edge area 522, the top surface of the edge area 522 is gradually inclined towards the direction of the fire divider 20, that is, the inner flame hole 523 on the edge area 522 is inclined, so that the injection direction of the inner flame hole 523 on the edge area 522 is slightly outwardly inclined, forming a surrounding peripheral flame. The inclined design helps to expand the coverage of the flame, ensuring comprehensive heating of the bottom of the pot.

[0115] In this way, by the direction of the inner flame hole 523 being perpendicular to the surface of the area where it is located, the design of the inner flame hole 523 perpendicular to the surface helps to optimize the mixing efficiency of gas and air, ensuring sufficient combustion. The design of the thickened area 521 and the inclined edge area 522 helps to guide the flame to be evenly distributed to the pot, reducing the spread and off-flame phenomenon of the flame, improving the stability and safety of combustion.

[0116] In some embodiments of the present application, the outer edge area 522 is 5° with respect to the horizontal. The inner fire cover 50 is designed with five circles of inner flame holes 523. The diameter of the inner flame hole 523 is 2mm. The inner two circles of inner flame holes 523 are located on the thickened area 521 and are vertically upward, and the number of single-circle inner flame holes 523 is 4, 10, 10, 20, 26, and 32 from inside to outside.

[0117] In some embodiments of the present application, the outer side of the inner fire cover 50 is provided with an ignition boss 53.

[0118] In some embodiments of the present application, in order to improve the ignition performance of the flat plate burner 100 and ensure that the flame can burn normally, two ignition bosses 53 are provided on the outer side of the inner fire cover 50, corresponding to the ignition needle 61 and the thermocouple 62 respectively.

[0119] In some embodiments of the present application, the igniter 20 and the inner fire cover 50 are fastened and connected by screws.

[0120] In some embodiments of the present application, the igniter 20 is provided with a mounting hole 26, and the inner fire cover 50 is provided with a fixing boss 54. The fixing boss 54 is located in the inner uniform fire chamber 51. The mounting hole 26 and the fixing boss 54 are oppositely arranged. The igniter 20 and the inner fire cover 50 are fastened and connected by screws, bolts or the like passing through the mounting hole 26 and being fixed in the fixing boss 54.

[0121] In some embodiments of the present application, the mounting hole 26 and the fixing boss 54 are respectively provided with two, so as to improve the stability of the connection.

[0122] In some embodiments of the present application, in order to improve the fool-proof effect of the flat burner 100 and avoid the user from placing it incorrectly, the two ignition bosses 53 are asymmetrically arranged on the inner fire cover 50. In use, the inner fire cover 50 is placed on the igniter 20, the igniter 20 is rotated to make the two ignition bosses 53 respectively face the ignition needle 61 and the thermocouple 62, and then the igniter 20 is fastened and connected with the inner fire cover 50 as a whole by screws installed from the back of the igniter 20.

[0123] The stove 200 provided by the present application comprises a panel 201, a bottom shell 202 and a flat burner 100. The panel 201 is provided with a cooking eye. The bottom shell 202 is installed below the panel 201 and surrounds the panel 201 to form an installation cavity. The flat burner 100 is installed in the installation cavity and partially protrudes out of the cooking eye and beyond the panel 201. The flat burner 100 comprises a burner head 10, an igniter 20, an outer fire cover 30, a uniform fire plate 40 and an inner fire cover 50. The burner head 10 is arranged in the installation cavity and is used for inputting gas. The igniter 20 is arranged on the burner head 10 and is located in the cooking eye. The igniter 20 is configured with a gas mixing chamber 21, an inner gas channel 22 and at least two outer gas channels 23. The gas mixing chamber 21 is in communication with the burner head 10. The inner gas channel 22 and the at least two outer gas channels 23 are respectively in communication with the gas mixing chamber 21. The at least two outer gas channels 23 are arranged around the inner gas channel 22. The outer fire cover 30 is arranged on the top of the igniter 20 and forms an annular outer uniform fire chamber 31 with the igniter 20. The at least two outer gas channels 23 are respectively in communication with the outer uniform fire chamber 31. The uniform fire plate 40 is arranged in the outer uniform fire chamber 31 and is located above the outer gas channel 23. The inner fire cover 50 is arranged on the top of the igniter 20 and forms an inner uniform fire chamber 51 with the igniter 20. The inner gas channel 22 is in communication with the inner uniform fire chamber 51. The uniform fire plate 40 is provided with a plurality of honeycomb holes 41. The honeycomb holes 41 are opposite to the outer gas channel 23.

[0124] In this way, by designing the gas distributor 20 on the burner head 10, the gas and air can be fully mixed in the mixing chamber 21, the inner air channel 22 and the outer air channel 23, and further mixed through the inner and outer uniform flame chambers formed between the gas distributor 20 and the inner flame cap 50 and the outer flame cap 30. By providing the honeycomb holes 41 on the uniform flame plate 40, the honeycomb holes 41 are opposite to the outer air channel 23, so that the mixed gas entering the outer uniform flame chamber 31 from the outer air channel 23 can slow down the gas flow rate entering the outer uniform flame chamber 31 under the blocking effect of the honeycomb holes 41, so that the gas and air can be uniformly distributed in each area of the outer uniform flame chamber 31, and the combustion is more uniform. At the same time, slowing down the gas flow rate through the honeycomb holes 41 helps to maintain the stability of the flame on the outer flame cap 30, preventing the flame from being unstable or extinguished due to too fast gas flow. Uniformly distributed gas and stable flame help to improve combustion efficiency, ensure that the gas can be fully burned, reduce energy waste, and reduce use cost. Moreover, the design of the honeycomb holes 41 can reduce the noise generated when the gas flows, so that the cooking appliance 200 is more quiet during use, improving user experience. Uniform heat distribution can also reduce the local high temperature pressure of the flame cap, reduce the thermal fatigue and loss of the material, thereby prolonging the service life of the flame cap.
