[0027] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0028] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They 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 direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0029] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0030] The embodiment of the present invention provides a reversible burner suitable for high energy efficiency, such as Figure 1-5 As shown, the burner body 100 includes a burner plate grating 300, an adapter assembly 400, and an air intake assembly 500. The energy-gathering grating 300 is mounted on the burner body 100. Specifically, the energy-gathering grating 300 can be fixed to the burner body 100, integrally formed with the burner body 100, or placed on the burner body 100, allowing the energy-gathering grating 300 to be removed from or placed on the burner body 100 at any time. The burner body 100 includes an air intake pipe 130 at its bottom, through which gas and primary air enter the burner body 100. The adapter assembly 400 is fixed to the bottom of the burner body 100 and rotatably connected to the air intake assembly 500. The air intake assembly 500 is fixed to the stove body. When the adapter assembly 400 rotates relative to the air intake assembly 500, the burner body 100 can also rotate relative to the stove body. The burner body 100 can be rotated to Figure 1 and Figure 2 In the horizontal state shown in FIG, for normal use, the burner body 100 can also be rotated to Figure 3 and Figure 4 The flipped state shown in the figure makes it easier for the user to clean the panel of the cooker.

[0031] The adapter assembly 400 includes an ejector tube 410 and a sidewall 420. The ejector tube 410 is a Venturi tube used to accelerate the flow of gas. The outlet end of the ejector tube 410 interfaces with the intake pipe 130. The intake assembly 500 includes a nozzle 510 and a support plate 530. The sidewall 420 is rotatably connected to the support plate 530. When the sidewall 420 rotates relative to the support plate 530, the entire burner body 100 rotates relative to the intake assembly 500. When the burner body 100 rotates to a horizontal position relative to the intake assembly 500, the nozzle 510 interfaces concentrically with the intake end of the ejector tube 410. The nozzle 510 sprays gas into the ejector tube 410. Under the influence of the airflow, the primary air and gas enter the ejector tube 410 together and then enter the burner body 100 through the intake 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 .

[0032] In existing flip-type burners, the rotation axis and ejector tube are typically at the same height. This design in this embodiment raises the rotation axis of the adapter assembly 400 and the air intake assembly 500, positioning the energy-concentrating hob 300 higher and further away from the cooktop. This prevents the energy-concentrating hob 300 from contacting the cooktop during the flipping of the burner body 100, allowing the burner body 100 to rotate to a vertical position. This increases the burner's flip angle and enhances the user experience. Furthermore, by separating the traditional air intake duct into the intake duct 130 and the ejector tube 410, their combined length can be greater than that of a conventional intake duct. This increases the distance between the energy-concentrating hob 300 and the cooktop when the burner body 100 is flipped, further reducing the chance of the energy-concentrating hob 300 contacting the cooktop.

[0033] In some embodiments, as Figure 3 、 Figure 6 and Figure 7 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 that is biased to the right. 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 have 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.

[0034] This embodiment allows the ejector tube 410 to be positioned lower, and accordingly, the intake pipe 130, which interfaces with the ejector tube 410, is also positioned lower. This allows the rotation axis 401 of the adapter assembly 400 and the intake assembly 500 to be positioned at a height greater than that of the ejector tube 410. The ejector tube 410, sidewall 420, and connecting plate 430 can be integrally formed to facilitate the integral molding of the adapter assembly 400 and enhance the connection strength among the ejector tube 410, sidewall 420, and connecting plate 430.

[0035] Further, such as Figure 6 and Figure 8 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 .

[0036] In this embodiment, the connecting column 140 and the connecting flange 440 can be fastened together by screws.

[0037] In some embodiments, as Figure 1-5 As shown, the air intake assembly 500 also includes a nozzle holder 520, the nozzle 510 is fixed on the top of the nozzle holder 520, and the support plate 530 is arranged on the top surface of the nozzle holder 520 and extends upward, which makes the rotating axis 401 relatively far away from the top surface of the nozzle holder 520, and the energy-gathering disk grate 300 is not easy to touch the panel.

[0038] 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.

[0039] 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.

[0040] In some embodiments, as Figure 5-8 As shown, two air inlet pipes are provided: an outer ring air inlet pipe 132 and an inner ring air inlet pipe 131. Two ejector pipes 410 and two nozzles 510 are provided, with the outlet ends of the two ejector pipes 410 docking with the outer ring air inlet pipe 132 and the inner ring air inlet pipe 131, respectively. When the burner body 100 is rotated to a horizontal position relative to the air inlet assembly 500, the two nozzles 510 dock concentrically with the air inlet ends of the two ejector pipes 410, respectively. The mixed gas in the outer ring air inlet pipe 132 is used to form the outer ring fire, while the mixed gas in the inner ring air inlet pipe 131 is used to form the inner ring fire, making the burner of this embodiment a double ring fire burner.

[0041] 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 to 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 to the inner ring burner head 111 and the outer ring burner head 112. In this embodiment, the inner ring burner head 111 is not fixedly connected to the outer ring burner head 112 by means of other connecting structures, but instead utilizes the existing air inlet pipe to connect the inner ring burner head 111 and the outer ring burner head 112, which can simplify the connecting structure.

[0042] The embodiment of the present utility model further provides a stove, such as Figure 9As shown, it includes a stove body and a reversible burner suitable for high energy efficiency according to any of the above embodiments. For detailed description of the reversible burner suitable for high energy efficiency, please refer to the above embodiments and will not be repeated here.

[0043] The cooker body includes a panel 610 and a bottom shell 620 disposed at the bottom of the panel 610. The burner body 100, the energy-concentrating plate hob 300, and the adapter assembly 400 are all disposed above the panel 610. The air intake assembly 500 is fixed to the panel 610. When the adapter assembly 400 rotates relative to the air intake assembly 500, the burner body 100 also rotates relative to the cooker body.

[0044] This design of this embodiment elevates the rotational axis of the adapter assembly 400 and the air intake assembly 500, positioning the energy-concentrating hob 300 higher and further away from the cooktop panel 610. This prevents the energy-concentrating hob 300 from contacting the cooktop panel 610 during the flipping of the burner body 100, allowing the burner body 100 to rotate to a vertical position. This increases the burner's flipping angle and enhances the user experience. Furthermore, by separating the traditional air intake duct into an intake duct and an ejector duct, the combined length of the two components can be greater than that of a traditional air intake duct. This increases the distance between the energy-concentrating hob 300 and the cooktop panel 610 when the burner body 100 is flipped, further reducing the energy-concentrating hob 300's contact with the cooktop panel 610.

[0045] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
