[0047] The present invention provides the following description with reference to the accompanying drawings to assist in a comprehensive understanding of various embodiments of the present invention as defined by the claims and their equivalents. The description includes various specific details to assist in understanding, but these details should be considered as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0048] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0049] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0050] The embodiment of the present invention provides a reversible burner which is convenient for disassembly and assembly of the heat insulation plate. Figure 1-3 As shown, it includes a burner body 100 and a heat insulation plate 700. A support foot 150 is provided at the bottom of the burner body 100, and one or more support feet 150 can be provided. When the burner is flipped to a horizontal use state, the support foot 150 abuts against the panel of the cooker to stably support the burner body 100 so that the burner body 100 remains stable. A support guide structure 160 is provided on the support foot 150, and the support guide structure 160 is used to support the heat insulation plate 700 and provide support force for the heat insulation plate 700 to remain stable. At the same time, the support guide structure 160 can guide the heat insulation plate 700, and the user can insert the heat insulation plate 700 under the burner body 100 or withdraw it from the bottom of the burner body 100 through the support guide structure 160. A hanger 170 is also provided at the bottom of the burner body 100 , and a hanging groove 710 matched with the hanger 170 is provided on the heat insulation plate 700 . After the heat insulation plate 700 is inserted under the burner body 100 , the hanger 170 can be hooked in the hanging groove 710 .

[0051] When installing the heat insulation plate 700, it is only necessary to insert the heat insulation plate 700 into the bottom of the burner body 100 through the support guide structure 160, and the hanger 170 is hooked in the corresponding hanging groove 710. The hanger 170 and the support guide structure 160 jointly support and fix the heat insulation plate 700, and the installation of the heat insulation plate 700 is completed; when removing the heat insulation plate 700, it is only necessary to separate the hanger 170 from the hanging groove 710, and then pull the heat insulation plate 700 out from the bottom of the burner body 100 through the support guide structure 160, and the removal of the heat insulation plate 700 is completed; therefore, this embodiment omits the process of screwing and removing screws, facilitates the installation and removal of the heat insulation plate 700, and it is also more convenient for users to clean the bottom of the heat insulation plate 700 and / or the burner body 100.

[0052] In some embodiments, the hanger 170 includes a rod and a hook, the upper end of the rod is connected to the burner body 100, and the lower end is connected to the hook, and the width of the hook is greater than the width of the rod. The hanging groove 710 includes a first hanging groove 711 and a second hanging groove 712 connected to the first hanging groove 711. In the insertion direction of the heat insulation plate 700, the first hanging groove 711 is located in front of the second hanging groove 712. The first hanging groove 711 allows the hook to pass through, and the width of the second hanging groove 712 is greater than the width of the rod and less than the width of the hook, and the hook can be hooked below the second hanging groove 712.

[0053] When installing the heat insulation tray 700, the hook portion passes through the first hanging groove portion 711 and moves to the bottom of the heat insulation tray 700. As the heat insulation tray 700 is further inserted, the rod portion moves from the first hanging groove portion 711 to the second hanging groove portion 712, and the hook portion moves to the bottom of the second hanging groove portion 712 accordingly. Since the width of the second hanging groove portion 712 is smaller than the width of the hook portion, the hook portion cannot pass through the second hanging groove portion 712, and thus is hooked to the bottom of the second hanging groove portion 712. When disassembling the heat insulation tray 700, the rod portion moves from the second hanging groove portion 712 to the first hanging groove portion 711, and the hook portion moves to the bottom of the first hanging groove portion 711 accordingly, and then passes through the second hanging groove portion 712, so that the entire hanger 170 is separated from the hanging groove 710.

[0054] In this embodiment, the hanger 170 may be a screw, the rod of the screw is the rod of the hanger 170, and the head of the screw is the hook of the hanger 170. The hanging groove 710 may be a "T" shaped structure, the wider portion is the first hanging groove portion 711, and the narrower portion is the second hanging groove portion 712.

[0055] Furthermore, the heat insulation plate 700 includes an upwardly protruding boss 720, and the hanging groove 710 is arranged on the top surface of the boss 720. The arrangement of the boss 720 shortens the distance from the hanging groove 710 to the hanger 170, so that the hanger 170 does not need to protrude downward for an excessive distance.

[0056] At the same time, the first hanging groove 711 extends to the side of the boss 720 along the insertion direction of the heat insulation disk 700. When the heat insulation disk 700 is inserted under the burner body 100, the hook portion passes through the first hanging groove 711 on the side of the boss 720. As the heat insulation disk 700 is further inserted, the rod moves from the first hanging groove 711 to the second hanging groove 712. When the heat insulation disk 700 is withdrawn from the bottom of the burner body 100, the hook portion passes through the first hanging groove 711 on the side of the boss 720 to separate the hanger 170 from the hanging groove 710. Therefore, the heat insulation plate 700 can be moved in the insertion direction to enable the hanger 170 to be hooked in the hanging groove 710, and can be moved in the withdrawal direction to enable the hanger 170 to be separated from the hanging groove 710. There is no need for the heat insulation plate 700 to move in the vertical direction to allow the hanging part to pass through the first hanging groove part 711, which further facilitates the installation and disassembly of the heat insulation plate 700.

[0057] In some embodiments, the bottom surface of the heat insulation plate 700 is provided with a plurality of protruding support platforms 730. When the burner is in a horizontal use state, the protruding support platforms 730 can abut against the panel of the cooker to reduce the force on the hanging part 170 and extend the service life of the hanging part 170.

[0058] In some embodiments, two groups of support legs 150 are provided, and the two groups of support legs 150 are respectively located on both sides of the heat insulation disc 700. The support guide structure 160 is a support guide groove provided on the inner side surfaces of the support legs 150, and the support guide groove extends along the insertion direction of the heat insulation disc 700. In the process of inserting the heat insulation disc 700 under the burner body 100 and in the process of withdrawing from the bottom of the burner body 100, the two sides of the heat insulation disc 700 slide in the support guide grooves of the two groups of support legs 150 respectively, and the support guide groove plays a role of limiting and guiding the heat insulation disc 700, and the bottom wall of the support guide groove can support the heat insulation disc 700.

[0059] In some embodiments, Figure 1 and Figure 4 As shown, the supporting foot 150 includes a supporting foot body 151 and a connecting block 152. The connecting block 152 is arranged at the bottom of the supporting foot body 151 and is fixedly connected to the supporting foot body 151. A supporting guide groove is formed between the supporting foot body 151 and the connecting block 152. This embodiment forms the supporting guide groove through a split structure, eliminating the grooving process.

[0060] The support foot body 151 and the connecting block 152 can be fastened together by a fixing member 155 such as a screw. Figure 4 As shown, a notch can be provided on the right side of the bottom of the supporting foot body 151, and a protrusion can be provided on the right side of the top of the connecting block 152. The protrusion is embedded in the notch, and a supporting guide groove is formed between the top wall of the notch and the top surface of the protrusion.

[0061] Furthermore, a protective cover 153 is provided on the outer side of the connecting block 152. The protective cover 153 can play the role of elastic buffer and can be made of soft materials such as silicone and rubber. When the burner rotates from the flipped state to the horizontal state, the bottom of the support leg 150 will touch the panel of the stove. The protective cover 153 can reduce the force on the panel, so that the support leg 150 is not easy to damage the panel of the stove.

[0062] The embodiment of the present invention also provides another reversible burner that facilitates the disassembly and assembly of the heat insulation plate. Compared with the above embodiment, this embodiment provides another installation method of the heat insulation plate. The heat insulation plate can be inserted under the burner body or pulled out from the bottom of the burner body; the bottom of the burner body is arranged with two hangers front and back along the insertion direction of the heat insulation plate, and the heat insulation plate is provided with two hanging grooves respectively adapted to the two hangers. After the heat insulation plate is inserted under the burner body, the two hangers are respectively hooked in the two hanging grooves to achieve the installation of the heat insulation plate. Since the hangers are arranged front and back along the insertion direction of the heat insulation plate, the two hangers can hook up the heat insulation plate one after the other to keep the heat insulation plate stable. When the heat insulation plate is pulled out from the bottom of the burner body, the two hangers are respectively disengaged from the two hanging grooves to achieve the disassembly of the heat insulation plate.

[0063] In some embodiments, the hanger includes a rod and a hook, the upper end of the rod is connected to the burner body, and the lower end is connected to the hook, and the width of the hook is greater than the width of the rod. The hanging groove includes a first hanging groove and a second hanging groove connected to the first hanging groove. In the insertion direction of the heat insulation plate, the first hanging groove is located in front of the second hanging groove. The first hanging groove allows the hook to pass through, the width of the second hanging groove is greater than the width of the rod and less than the width of the hook, and the hook can be hooked below the second hanging groove.

[0064] When installing the heat insulation plate, the hook part passes through the first hanging groove part and moves to the bottom of the heat insulation plate. As the heat insulation plate is further inserted, the rod part moves from the first hanging groove part to the second hanging groove part, and the hook part moves to the bottom of the second hanging groove part accordingly. Since the width of the second hanging groove part is smaller than the width of the hook part, the hook part cannot pass through the second hanging groove part, and thus is hooked to the bottom of the second hanging groove part. When removing the heat insulation plate, the rod part moves from the second hanging groove part to the first hanging groove part, and the hook part moves to the bottom of the first hanging groove part accordingly, and then passes through the second hanging groove part, so that the entire hanging part is separated from the hanging groove.

[0065] In this embodiment, the hanging part can be a screw, the rod of the screw is the rod of the hanging part, and the head of the screw is the hook part of the hanging part. The hanging groove can be a "T" shaped structure, the wider part is the first hanging groove part, and the narrower part is the second hanging groove part.

[0066] Furthermore, the heat insulation plate includes two bosses protruding upwards, and two hanging grooves are respectively arranged on the top surfaces of the two bosses, and the two bosses are arranged front and back along the insertion direction of the heat insulation plate. The arrangement of the bosses shortens the distance from the hanging groove to the hanging part, so that the hanging part does not need to protrude downwards too far.

[0067] Meanwhile, the first hanging groove portion extends to the side of the boss along the insertion direction of the insulation disk, and the height of the boss located at the front side of the insertion direction of the insulation disk is smaller than the height of the boss located at the rear side of the insertion direction of the insulation disk.

[0068] During the process of inserting the heat insulation disk under the burner body, the hook portion passes through the first hanging groove portion through the first hanging groove portion on the side of the boss, and as the heat insulation disk is further inserted, the rod portion moves from the first hanging groove portion to the second hanging groove portion. During the process of withdrawing the heat insulation disk from the bottom of the burner body, the hook portion passes through the first hanging groove portion through the first hanging groove portion on the side of the boss to separate the hanger from the hanging groove. Thus, the heat insulation disk can be moved along the insertion direction to hook the hanger in the hanging groove, and can be moved along the withdrawal direction to separate the hanger from the hanging groove. There is no need for the heat insulation disk to move in the vertical direction to allow the hook portion to pass through the first hanging groove portion, which further facilitates the installation and removal of the heat insulation disk.

[0069] Since the height of the boss located on the front side of the insertion direction of the insulation disk is smaller than the height of the boss located on the rear side of the insertion direction of the insulation disk, the boss on the front side will not interfere with the hanger on the rear side during the process of inserting the insulation disk under the burner body. Therefore, the hanger located on the front side of the insertion direction of the insulation disk can be hooked in the hanging groove of the boss located on the front side of the insertion direction of the insulation disk, and the hanger located on the rear side of the insertion direction of the insulation disk can be hooked in the hanging groove of the boss located on the rear side of the insertion direction of the insulation disk, so that the two hangers are hooked in different hanging grooves at the same time or detached from different hanging grooves at the same time.

[0070] The embodiment of the present invention further provides an embodiment, based on the above embodiment, as Figure 5-11 As shown, the burner of this embodiment further includes a thermocouple 210, an ignition needle 220 and a cover plate 230.

After removing the stove rack 300, it is convenient to clean the stove rack 300 and the burner head. When the stove rack 300 is placed on the burner head, the pins 310 of the stove rack 300 are inserted into the sockets 105, and the stove rack 300 is positioned by the cooperation of the sockets 105 and the pins 310, and the stove rack 300 is restricted from lateral movement relative to the burner head, thereby stably supporting the pot. In addition, when the burner of this embodiment is a flip-type burner, the stove rack 300 is not easy to fall off the burner head during the flipping process of the burner.

[0079] Furthermore, the burner head may include an inner ring burner head and an outer ring burner head arranged outside the inner ring burner head, the outer ring burner head includes an outer ring wall 106 and a ring plate 107 located outside the outer ring wall 106, the outer ring wall 106 may protrude vertically upward to form the outer side surface of the outer ring mixing groove, when the outer ring fire cover 122 is placed on the outer ring burner head, the outer ring wall 106 is used to support the outer ring fire cover 122, and the socket 105 is arranged on the ring plate 107, and this structure does not interfere with the outer ring fire cover 122.

[0080] Furthermore, the burner body 100 further includes an inner ring fire cover 121, and the inner ring fire cover 121 is disposed on the inner ring burner head.

[0081] In some embodiments, the stove rack 300 includes a plurality of support plates 320 for supporting the pots, and the pins 310 and the support plates 320 are integrally formed, which facilitates the installation of the pins 310 and simplifies the molding process of the pins 310 .

[0082] The embodiment of the present invention also provides another burner, based on the above embodiment, such as Figure 12-16 As shown, the burner of this embodiment further includes a furnace rack 300, an adapter assembly 400 and an air intake assembly 500. The furnace rack 300 can be designed in the shape of an energy-gathering disk, which can be used for windproof and energy gathering. The furnace rack 300 is arranged on the burner body 100. Specifically, the furnace rack 300 can be fixed on the burner body 100, or can be integrally formed with the burner body 100, or can be placed on the burner body 100, so that the furnace rack 300 can be removed from the burner body 100 or placed on the burner body 100 at any time. The burner body 100 includes an air intake pipe 130 located at the bottom thereof, and the gas and primary air enter the burner body 100 through the air intake pipe 130. The adapter assembly 400 is fixed to the bottom of the burner body 100 and is rotatably connected to the air intake assembly 500. The air intake assembly 500 is used to be fixed on the stove body. When the adapter assembly 400 rotates relative to the air intake assembly 500, the burner body 100 can rotate relative to the stove body. The burner body 100 can be rotated to Fig.12 and Fig.13 In the horizontal state shown in FIG. 1 , for normal use, the burner body 100 can also be rotated to Fig.14 and Fig.15 The flipped state shown in the figure makes it convenient for the user to clean the panel of the cooker.

[0083] The adapter assembly 400 includes an ejector tube 410 and a side wall 420. The ejector tube 410 is a venturi tube for accelerating the flow of gas. The gas outlet end of the ejector tube 410 is connected to the gas inlet pipe 130. The gas inlet assembly 500 includes a nozzle 510 and a support plate 530. The side wall 420 is rotatably connected to the support plate 530. When the side wall 420 rotates relative to the support plate 530, the entire burner body 100 can rotate relative to the gas inlet assembly 500. When the burner body 100 rotates to a horizontal state relative to the gas inlet assembly 500, the nozzle 510 is concentrically connected to the gas inlet end of the ejector tube 410, and the nozzle 510 sprays gas to the ejector tube 410. Under the action of the airflow, the primary air and the gas enter the ejector tube 410 together, and then enter the burner body 100 through the gas inlet pipe 130. When the burner body 100 rotates to a horizontal state relative to the air intake assembly 500 , the height of the rotation axis 401 of the side wall 420 and the support plate 530 is greater than the height of the ejector tube 410 .

[0084] The rotation axis of the existing flip burner is usually at the same height as the ejector tube. The design of this embodiment is equivalent to raising the rotation axis of the adapter assembly 400 and the air intake assembly 500, so that the position of the grate 300 is higher and farther away from the panel of the stove. During the flipping of the burner body 100, the grate 300 is not easy to touch the stove panel. The burner body 100 can be rotated to a vertical state, which increases the flip angle of the burner and improves the user experience. At the same time, the traditional air intake duct is divided into the air intake duct 130 and the ejector tube 410, and the overall length of the two can be greater than the length of the traditional air intake duct, which is equivalent to increasing the distance from the grate 300 to the stove panel when the burner body 100 is in the flip state, and makes it more difficult for the grate 300 to touch the stove panel.

[0085] In some embodiments, Fig.14 , Fig.17 and Fig.18 As shown, the adapter assembly 400 also includes a connecting plate 430, the ejector tube 410 is arranged at the bottom of the connecting plate 430, and the connecting plate 430 has a protrusion 431 extending upward at the tail end in the ejection direction. The ejection direction refers to the direction in which the ejector tube 410 ejects the gas. Figure 7 For example, the ejection direction is biased to the left, therefore, the tail end of the connecting plate 430 in the ejection direction is the end of the connecting plate 430 biased to the right, and the protrusion 431 can protrude obliquely upward or directly upward. The connecting plate 430 and the protrusion 431 extend downward on both the left and right sides of the ejection direction to form the side wall 420, which makes the side wall 420 present an "L"-shaped structure. The rotation axis 401 of the side wall 420 and the support plate 530 is located on the side wall 420 below the protrusion 431, and the height of the rotation axis 401 of the side wall 420 and the support plate 530 is greater than the height of the connecting plate 430.

[0086] This embodiment allows the ejector tube 410 to be positioned lower, and accordingly, the position of the air intake pipe 130 docking with the ejector tube 410 is also lower, so that the height of the rotation axis 401 of the adapter assembly 400 and the air intake assembly 500 can be greater than the height of the ejector tube 410. The ejector tube 410, the side wall 420 and the connecting plate 430 can be integrally formed, so as to facilitate the integral forming of the adapter assembly 400 and strengthen the connection strength between the ejector tube 410, the side wall 420 and the connecting plate 430.

[0087] Further, such as Fig.17 and Fig.19 As shown, connecting flanges 440 are provided on the outer sides of the two side walls 420 , and the bottom of the burner body 100 has a connecting column 140 extending downward, which is fixedly connected to the connecting flange 440 to fix the adapter assembly 400 to the bottom of the burner body 100 .

[0088] In this embodiment, the connection column 140 and the connection flange 440 can be fastened together by screws.

[0089] In some embodiments, Figure 12-16 As shown, the air intake assembly 500 also includes a nozzle seat 520, the nozzle 510 is fixed on the top of the nozzle seat 520, and the support plate 530 is arranged on the top surface of the nozzle seat 520 and extends upward, so that the rotation axis 401 is relatively far away from the top surface of the nozzle seat 520, and the furnace frame 300 is not easy to touch the panel.

[0090] When the adapter assembly 400 includes two side walls 420 , two support plates 530 are also provided, and the two support plates 530 are rotatably connected to the two side walls 420 respectively.

[0091] In some embodiments, the ejector tube 410 may be inserted into the air intake pipe 130 to ensure that the ejector tube 410 and the air intake pipe 130 are accurately docked and gas leakage may be greatly reduced.

[0092] In some embodiments, Figure 16-19 As shown, two air inlet pipes are provided, namely, an outer ring air inlet pipe 132 and an inner ring air inlet pipe 131, and two ejector pipes 410 and two nozzles 510 are provided. The gas outlet ends of the two ejector pipes 410 are respectively connected with the outer ring air inlet pipe 132 and the inner ring air inlet pipe 131. When the burner body 100 is rotated to a horizontal state relative to the air inlet assembly 500, the two nozzles 510 are respectively connected with the air inlet ends of the two ejector pipes 410 concentrically. The mixed gas in the outer ring air inlet pipe 132 is used to form an outer ring fire, and the mixed gas in the inner ring air inlet pipe 131 is used to form an inner ring fire, so that the burner of this embodiment is a double ring fire burner.

[0093] Furthermore, the burner body 100 includes an inner ring burner head 111 and an outer ring burner head 112 arranged around the outer side of the inner ring burner head 111. The inner ring burner head 111 is provided with an inner ring gas mixing chamber, and the outer ring burner head 112 is provided with an outer ring gas mixing chamber. The outer ring air inlet pipe 132 and the inner ring air inlet pipe 131 are respectively connected with the outer ring gas mixing chamber and the inner ring gas mixing chamber to pass the gas into the gas mixing chamber for mixing. At the same time, the outer ring air inlet pipe 132 and the inner ring air inlet pipe 131 are both fixedly connected with the inner ring burner head 111 and the outer ring burner head 112. The inner ring burner head 111 of this embodiment is not fixedly connected with the outer ring burner head 112 by other connection structures, but uses the existing air inlet pipe to connect the inner ring burner head 111 and the outer ring burner head 112, which can simplify the connection structure.

[0094] An embodiment of the present invention further provides a cooker, such as Fig. 20 As shown, it includes a stove body and a burner of any of the above embodiments. The specific description of the burner can refer to the above embodiments and will not be repeated here.
