[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0050] Please refer to Figure 1 and Figure 2 In one aspect, the present application provides a stove 1000, which includes a stove shell 200 and a burner assembly 100. The stove shell 200 includes a shell 203 and a panel 205. The shell 203 has a receiving cavity 201. At least part of the burner assembly 100 is installed in the receiving cavity 201, and the panel 205 covers the opening of the receiving cavity 201 to prevent the burner assembly 100 from being exposed to the air, thereby protecting the burner assembly 100. It can be understood that the embodiment of the present application does not limit the number of burner assemblies 100 provided in the stove 1000. For example, the stove 1000 may include one or two burner assemblies 100. When two burner assemblies 100 are included, the two burner assemblies 100 may be arranged side by side for easy operation by users.

[0051] Combination Figures 2 to 4 On the other hand, an embodiment of the present application proposes a burner assembly 100, which includes a mounting bracket 90, a first burner 10 and a second burner 30, an igniter 50, a guide ring 70 and an oil cup 60. The first burner 10 and the second burner 30, the igniter 50 and the guide ring 70 are all connected to the mounting bracket 90, and the mounting bracket 90 is connected to the stove body to provide a mounting basis for the above structure.

[0052] Specifically, the mounting bracket 90 may be made of copper, aluminum or alloy, wherein the alloy material may be stainless steel, for example, formed by forging, which is easy to process. The mounting bracket 90 may include a base 91, at least two connecting arms 93 and connecting ribs. The base 91 is connected to the stove body, for example, by bolts and other fixings to achieve fixed connection. At least two connecting arms 93 are connected to the circumference of the base 91, and the connecting ribs are connected to the base 91 and / or the connecting arms 93, for example, the connecting ribs may be connected to the base 91, or the connecting ribs may be connected to one connecting arm 93, or the connecting ribs may be connected between two adjacent connecting arms 93, so as to realize the connection between the two connecting arms 93 through the connecting ribs, and the connecting ribs may act as reinforcing ribs between the two connecting arms 93 to improve the strength of the connecting arms 93 and avoid deformation of the connecting arms 93.

[0053] The oil cup 60 can be made of stainless steel or a plate, wherein the oil cup 60 is fixed to the seat 91 and is located on the inner side of the inner ring fire hole 11, and a receiving cavity is formed in the oil cup 60. The receiving cavity can collect dirt generated during the cooking process, such as oil, liquid and debris generated by the cooking utensils during the cooking process. The oil cup 60 can be fixed to the seat 91 by directly placing the oil cup 60 inside the seat 91. When the receiving cavity of the oil cup 60 needs to be cleaned, the user can directly take the oil cup 60 out of the seat 91, which is easy to operate and improves the user experience.

[0054] The first burner 10 and the second burner 30 are both connected to the connecting arm 93. The first burner 10 is provided with an inner ring fire hole 11, and the second burner 30 is provided with an outer ring fire hole 31. It can be understood that the outer ring fire hole 31 is located outside the inner ring fire hole 11.

[0055] Specifically, the first burner 10 and the second burner 30 each include an ejection tube 13 and a burner head 15 fixedly connected to the ejection tube 13, and the burner head 15 is provided with an inner ring fire hole 11 or an outer ring fire hole 31. In the exemplary actual use process, when the user performs the ignition operation, the gas in the gas pipeline enters the burner head 15 through the ejection tube 13 of the first burner 10 for gas mixing, and the mixed gas then flows out from the inner ring fire hole 11; the igniter 50 has an ignition end 51, and the ignition end 51 emits an arc to ignite the mixed air flowing out of the inner ring fire hole 11 to generate an inner ring flame. When the gas in the gas pipeline increases, the gas will also enter the burner head 15 through the ejection tube 13 of the second burner 30 for gas mixing, and the mixed gas will then flow out from the outer ring fire hole 31. At this time, the igniter 50 will ignite the mixed air flowing out of the outer ring fire hole 31 to generate an outer ring flame. In this way, the bottom of the cooker is heated by wrapping the bottom of the cooker with the inner ring flame and the outer ring flame.

[0056] Optionally, the first burner 10 and the second burner 30 may both be an integral structure, or both include an upper shell and a lower shell. The upper shell and the lower shell may be made of stainless steel, copper alloy or aluminum alloy. When made of stainless steel, stainless steel has the advantages of low cost, long service life and high melting point to resist burning compared to copper. The upper shell and the lower shell may be formed in one step by forging or stamping to improve processing efficiency. The upper shell and the lower shell may be connected by welding after the upper shell and the lower shell are covered to achieve final fixation of the two, which has a strong connection effect.

[0057] Combination Figures 5 to 7 The first burner 10 and the second burner 30 are spaced apart, and the gap between them forms an air supply channel 101, through which secondary air can be supplied to the inner ring fire hole 11 and the outer ring fire hole 31. It can be understood that the first burner 10 and the second burner 30 are spaced apart in the height direction of the burner assembly 100, and the air supply channel 101 is located between the burner heads 15 of the two and is arranged in an annular shape. The igniter 50 is arranged in the air supply channel 101, and the ignition end 51 is located between the inner ring fire hole 11 and the outer ring fire hole 31.

[0058] The guide ring 70 is disposed in the air supply channel 101, and can be specifically disposed between the inner ring fire hole 11 and the outer ring fire hole 31, for guiding the secondary air. The guide ring 70 is constructed as an annular structure, so that the secondary air can be fully guided in the annular direction, thereby improving the secondary air supply efficiency. The guide ring 70 can be made of materials such as stainless steel, cold plate or aluminum alloy, which is not limited in the embodiment of the present application.

[0059] In the related art, since the guide ring 70 and the igniter 50 are both arranged in the air supply channel 101, the ignition end 51 is close to the guide ring 70. When the ignition end 51 discharges, the arc may be affected by the guide ring 70 and may become unstable, such as jumping. It cannot stably trigger ignition at the inner ring fire hole 11 and the outer ring fire hole 31, thus affecting the ignition efficiency.

[0060] Please refer to Figure 6 and Figure 7 To solve the above problem, the guide ring 70 in the embodiment of the present application is provided with a avoidance portion 75, which is located on the inner circumference of the guide ring 70, and the inner circumference of the guide ring 70 is closer to the inner ring fire hole 11. The avoidance portion 75 is arched in a direction away from the inner ring fire hole 11, thereby being higher than other parts of the inner circumference of the guide ring 70, and defining an avoidance space 751. At least part of the igniter 50 is located in the avoidance space 751, and the ignition end 51 is spaced apart from the guide ring 70.

[0061] It can be understood that by setting the avoidance space 751 in the guide ring 70 and setting at least a part of the igniter 50 in the avoidance space 751, the ignition end 51 and the guide ring 70 are spaced apart, and the distance between the ignition end 51 and the guide ring 70 is increased, so that when the ignition end 51 discharges and ignites, the influence of the guide ring 70 on the arc can be reduced or avoided, thereby improving the stability of the arc when the ignition end 51 discharges and ignites, and improving the ignition success rate.

[0062] In addition, since the avoidance portion of the guide ring 70 is arched to form an avoidance space 751, the igniter 50 is arranged in the avoidance space 751, which can reduce or avoid the influence of the guide ring 70 on the arc, and at the same time, make the space around the igniter 50 more sufficient, so as to facilitate the disassembly, assembly, maintenance and other operations of the igniter 50, thereby improving work efficiency. The arched avoidance portion 75 can also shield the igniter 50, and can prevent foreign matter such as oil stains from directly contacting the igniter 50, thereby ensuring the normal operation of the igniter 50 and improving product reliability.

[0063] Combination Figure 6 In one embodiment, the guide ring 70 includes a guide body 71 and a shielding cover 73. The guide body 71 is connected to the mounting bracket 90 and is arranged between the inner ring fire hole 11 and the outer ring fire hole 31, and the guide body 71 extends along the circumference of the inner ring fire hole 11, so as to be roughly arranged in an annular shape. The guide body 71 is used to guide the secondary air of the air supply channel 101. At the position of the guide body 71 corresponding to the avoidance portion 75, the inner circumference of the guide body 71 is provided with an avoidance notch 7111, and the open side of the notch at this position faces the inner side of the guide ring 70. The shielding cover 73 is connected to the inner circumference of the guide body 71, and is specifically connected to the outer circumference of the avoidance notch 7111. The shielding cover 73 is arched relative to the flow guide body 71 in a direction away from the inner ring fire hole 11, thereby defining an avoidance space 751, the avoidance space 751 is connected to the avoidance notch 7111, the igniter 50 is passed through the avoidance notch 7111, and is completely or partially located in the avoidance space 751. The shielding cover 73 may be in a hemispherical shape, a semi-cylindrical shape, a table shape, etc., which is not limited here.

[0064] Optionally, the shielding cover 73 and the guide body 71 are an integral structure, that is, part of the structure on the inner circumference of the guide ring 70 is warped in a direction away from the inner ring fire hole 11, thereby forming the shielding cover 73, and the remaining part is formed as the guide body 71. Specifically, after the guide ring 70 is formed, the shielding cover 73 can be formed by stamping or the like, or the guide ring 70 can be integrally cast. The integrally arranged guide ring 70 has better structural integrity and is more convenient to manufacture, thereby improving the processing efficiency. Of course, the shielding cover 73 and the guide body 71 can also be two independent components, and the shielding cover 73 and the guide body 71 can be made of the same or different materials, and can be assembled into the guide ring 70 by welding, bolting, etc. after each is formed.

[0065] Please refer to Figure 6 and Figure 7 In one embodiment, the guide body 71 includes a connecting foot 713 and a guide plate 711. The guide plate 711 is arranged in an annular shape and extends along the circumference of the inner ring fire hole 11 to guide the secondary air of the air supply channel 101. The guide plate 711 is provided with the above-mentioned avoidance notch 7111, and the shielding cover 73 is connected to the guide plate 711. The connecting foot 713 is arranged on the outer periphery of the guide plate 711 and is connected to the mounting bracket 90. It can be understood that the guide body 71 can be provided with a plurality of connecting feet 713, such as two or three, and the plurality of connecting feet 713 are all connected to the mounting to improve the stability of the guide body 71.

[0066] Specifically, in the direction away from the seat body 91, the connecting arm 93 is provided with a first fixing portion 931, a second fixing portion 933 and a third fixing portion 935 in sequence, the first burner 10 is connected to the first fixing portion 931, the guide plate 711 is connected to the second fixing portion 933, and the second burner 30 is connected to the third fixing portion 935. In the height direction of the burner assembly 100, the first fixing portion 931 is also higher than the third fixing portion 935, so that the first burner 10 and the second burner 30 can have a height difference. It can be understood that in the structural form in which the mounting bracket 90 has a plurality of connecting arms 93, each connecting arm 93 is provided with a first fixing portion 931, a second fixing portion 933 and a third fixing portion 935, so as to increase the contact area between the first burner 10, the second burner 30 and the guide ring 70 and the mounting bracket 90, and improve the structural stability. Furthermore, by providing the first fixing portion 931 , the second fixing portion 933 and the third fixing portion 935 on the mounting bracket 90 , the assembly of the first burner 10 , the second burner 30 and the guide ring 70 is facilitated.

[0067] Optionally, the connecting foot 713 extends along the height direction of the burner assembly 100, one end of which is connected to the guide plate 711, and the other end is connected to the second fixing portion 933, so that the guide plate 711 is erected between the first burner 10 and the second burner 30. The connection between the connecting foot 713 and the second fixing portion 933 can be welded or bolted. Figure 7 In the illustrated embodiment, a connecting ear is bent at one end of the connecting leg 713 away from the guide plate 711 to increase the contact area with the second fixing portion 933. The connecting ear is provided with a first connecting hole, and the second connecting portion is provided with a second connecting hole. A fastener, such as a bolt, is passed through the first connecting hole and the second connecting hole to fix the connecting leg 713 to the second fixing portion 933, thereby improving the connection reliability.

[0068] Further, continue to refer to Figure 7In one embodiment, the first fixing portion 931 is adjacent to the second fixing portion 933, and in the height direction of the burner assembly 100, the first fixing portion 931 is lower than the second fixing portion 933, thereby a step structure is formed by a height difference between the first fixing portion 931 and the second fixing portion 933, and the edge of the first burner 10 is located at the first fixing portion 931, and a portion of the connecting leg 713 extends to the top of the first fixing portion 931, thereby cooperating with the first fixing portion 931 to clamp the first burner 10, thereby strengthening the fixation of the first burner 10 and further improving the connection stability between the first burner 10 and the mounting bracket 90.

[0069] The guide plate 711 can divide the secondary air into two sub-air flows, one of which will flow to the inner ring fire hole 11, and the other will flow to the outer ring fire hole 31, so as to reduce the air grabbing situation between the flames generated by the inner ring fire hole 11 and the outer ring fire hole 31, thereby improving the combustion efficiency of the combustion stove and the burner.

[0070] Please refer to Figures 5 to 7 , further, along the radial direction of the guide plate 711, the guide plate 711 is inclined toward the direction close to the inner ring fire hole 11. Specifically, the guide plate 711 has an inner edge and an outer edge, and along the radial direction of the guide plate 711, the guide plate 711 is gradually inclined downward. In this way, under the inclined guidance of the guide plate 711, the secondary air can flow to the inner ring fire hole 11 more smoothly, thereby improving the combustion efficiency of the flame at the inner ring fire hole 11.

[0071] In one embodiment, along the axial projection of the first burner 10 and the second burner 30, the inner contour of the guide plate 711 and the inner contour of the inner ring fire hole 11 at least partially overlap, so that the guide plate 711 can guide air to the inner ring fire hole 11. In this embodiment, in the height direction of the burner assembly 100, the guide plate 711 is located above the inner ring fire hole 11, and along the axial projection of the first burner 10 and the second burner 30, the inner contour of the guide plate 711 and the inner contour of the inner ring fire hole 11 overlap or partially overlap, that is, the inner periphery of the guide plate 711 is located near the opening of the inner ring fire hole 11. In this embodiment, the guide plate 711 can guide the secondary air to the root of the flame of the inner ring fire hole 11, thereby improving the combustion efficiency. In addition, when dirt flows down in the height direction of the burner, the guide plate 711 can also block the dirt to prevent the dirt from flowing into the inner ring fire hole 11, thereby improving the reliability of the burner assembly 100. Moreover, foreign matter such as oil on the upper surface of the guide plate 711 can be guided into the seat body 91 or the oil cup 60 in the seat body 91 under the guidance of the guide plate 711. In actual use, the user can lay a paper towel or a bag on the seat body 91 to collect the dirt, and can directly replace the paper towel or bag with the dirt when cleaning is needed, which is convenient to operate.

[0072] Please refer to Figure 4 and Figure 5 In one embodiment, the mounting bracket 90 further includes a fixing bracket 95, the fixing bracket 95 is connected to the seat body 91, and the igniter 50 is connected to the fixing bracket 95. The burner assembly 100 also includes a thermocouple 80, which is used to sense the flame state and provide flameout protection. Specifically, the thermocouple 80 is composed of two different alloy materials. Different alloy materials will produce different thermoelectric potentials under the action of temperature. The two ends of the conductors of different components are connected to form a loop. When the temperature of the junction point is different, an electromotive force will be generated in the loop. In the abnormal flameout state, the thermoelectric potential of the thermocouple 80 disappears, and the solenoid valve on the gas pipeline will shut off the gas. During normal use, the continuous thermoelectric potential of the thermocouple 80 ensures that the solenoid valve of the gas pipeline is always in an open and ventilated state. In this way, the safety of the user in the process of using the burner assembly 100 can be guaranteed by detecting the thermocouple 80.

[0073] In order to make the burner assembly more compact and convenient for wiring, the thermocouple 80 and the igniter 50 are connected to the fixing frame 95. Optionally, a mounting boss is provided at one end of the fixing frame 95 away from the base 91, and an inclined surface is formed on the mounting boss. The thermocouple 80 and the igniter 50 installed on the fixing frame 95 can be arranged obliquely upward and penetrated with an avoidance opening, so that the staff can install the thermocouple 80 and the igniter 50 and improve the installation efficiency.

[0074] The thermocouple 80 is spaced apart from the igniter 50, and at least part of the thermocouple 80 and at least part of the igniter 50 are both located in the avoidance space 751. The avoidance portion 75 has a center line along the radial direction of the guide ring 70. It can be understood that when the burner assembly 100 is observed axially downward from the first burner 10 and the second burner 30, the center line divides the avoidance portion 75 into two equal parts. The part of the igniter 50 disposed in the avoidance space 751 is located on one side of the center line, and the part of the thermocouple 80 disposed in the avoidance space 751 is located on the other side of the center line. Among them, the igniter 50 is inclined relative to the radial direction of the guide ring 70 so that the ignition end 51 is close to the center line, thereby ensuring a sufficient spacing distance between the ignition end 51 and the guide ring 70, further avoiding the influence of the guide ring 70 on the ignition of the ignition end 51, thereby further improving the ignition success rate.

[0075] Of course, in other embodiments, the thermocouple 80 and the igniter 50 may also be separately arranged at different circumferential positions of the guide ring 70. In this case, the portion of the igniter 50 arranged in the avoidance space 751 extends along the center line, so that the ignition end 51 is located in the middle portion of the avoidance space 751, thereby ensuring a sufficient spacing distance between the ignition end 51 and the guide ring 70, further avoiding the influence of the guide ring 70 on the ignition of the ignition end 51, thereby further improving the ignition success rate.

[0076] Furthermore, in one embodiment, along the axial projection of the first burner 10 and the second burner 30, the ignition end 51 is exposed outside the avoidance portion 75, so that the ignition end 51 is further away from the guide ring 70, further increasing the distance between the ignition end 51 and the guide ring 70, thereby effectively preventing the influence of the guide ring 70 on the ignition of the ignition end 51, and further improving the ignition success rate.

[0077] Of course, in other embodiments, along the axial projection of the first burner 10 and the second burner 30, the ignition end 51 is located within the shielding range of the avoidance portion 75, so that the avoidance portion 75 can shield the ignition end 51, thereby preventing foreign matter such as oil stains above from directly contacting the ignition end 51 and affecting the normal use of the ignition end 51, thereby improving the reliability of the burner assembly 100.

[0078] The above is an explanation of the optional specific structure of the burner assembly 100 of the embodiment of the present application. Since the stove 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.
