[0027] The following embodiments are used to illustrate the present invention, but the present invention is not limited by these embodiments. Modifying the specific embodiments of the present invention or equivalently replacing some technical features without departing from the spirit of the present invention shall be covered within the scope of the technical solutions claimed by the present invention.

[0028] Embodiment 1:

[0029] As Figures 1 to 3 shown, this embodiment provides a rotatable burner, including a burner body 1, a tray 2, and a driving mechanism 3. The driving mechanism 3 is arranged on the tray 2, and the burner body 1 is arranged on the driving mechanism 3. The burner body 1 is driven to rotate by the driving mechanism 3.

[0030] In this embodiment, the rotatable burner includes a burner body 1, a tray 2, and a driving mechanism 3. The tray 2 is fixedly installed on the cooker. The driving mechanism 3 is arranged on the tray 2, and the burner body 1 is arranged on the driving mechanism 3. A cooking utensil is placed above the burner to heat the cooking utensil through the burner for cooking. The burner body 1 is driven to rotate by the driving mechanism 3, so that the burner body 1 serves as the active moving party in the relative movement between the pot and the fire, uniformly heating different areas of the cooking utensil, thereby achieving the purpose of uniform heating of food during cooking. The burner body 1 in this embodiment is made of metal material, but is not limited to metal material, and other more suitable materials can also be selected according to actual needs.

[0031] Furthermore, the driving mechanism 3 includes a plurality of driving components 4 distributed at intervals along the circumferential direction. The number of driving components 4 is 2N, where N is a non-zero natural number. The driving components 4 are used to drive the burner body 1 to move. By controlling the sequential operation of the plurality of driving components 4, the burner body 1 can be rotated. Its structure is simple, and the burner body can be further kept in a balanced state.

[0032] Preferably, the driving component 4 includes a driving member 5 and a supporting component 6. The driving member 5 and the supporting component 6 are arranged along the radial direction of the tray 2, and the driving member 5 is located outside the supporting component 6. The burner body 1 is supported by the supporting component 6, and the burner body 1 is driven to move on the supporting component 6 by the driving member 5. Its design is reasonable, and the burner body can be effectively driven to move on the supporting member by the driving member.

[0033] Specifically, the support assembly 6 at least includes a first support member 61 and a second support member 62. The first support member 61 and the second support member 62 are sequentially arranged from inside to outside along the radial direction of the tray 2. Its structure is simple, which can further ensure the stability of the burner body during movement.

[0034] In this embodiment, the first support member 61, the second support member 62, and the driving member 5 are all spherical, but are not limited to spherical shapes. They can also be any support structure with an arc-shaped notch. Of course, other more suitable support structures can also be selected according to actual needs. The surface of the top of the driving member 5 facing the center of the tray 2 is a concave arc surface. A first plane is provided at the top of the first support member 61, and a second plane is provided at the top of the second support member 62. Moreover, the centers of gravity of the first support member 61 and the second support member 62 are located directly below the centers of their planes. The diameter of the first support member 61 is smaller than that of the second support member 62, and the diameter of the second support member 62 is smaller than that of the driving member 5. The first support member 61, the second support member 62, and the driving member 5 are sequentially arranged from inside to outside along the radial direction of the tray 2. As a result, the height of the driving assembly 4 gradually increases from inside to outside on the horizontal line of the tray 2. In this way, the burner body 1 serves as the active moving party in the relative movement between the pot and the fire, heating different areas of the bottom of the pot, so as to achieve the purpose of uniform heating of food during cooking.

[0035] Preferably, an electromagnet is provided inside the driving member 5. The burner body 1 is made of a magnetic material or contains a magnetic material. By controlling the electromagnet inside the driving member 5 to be energized to generate magnetic force, the burner body 1 is driven to move in the direction of the driving member 5. Its structure is simple, which can ensure the reliability of the movement of the burner body 1.

[0036] In this embodiment, an electromagnet is provided inside the driving member 5, and the electromagnet is located in the upper half of the driving member 5. The driving member 5 is controlled by a switching power supply to generate or lose magnetic force in the electromagnet therein. The magnetic force generated after the electromagnet inside the driving member 5 is energized is sufficient to overcome the gravity of the burner body 1 and the frictional force between it and the support assembly 6. The burner body 1 is made of a magnetic material. After controlling the electromagnet inside the driving member 5 to generate magnetic force by being energized, under the action of the electromagnet principle, the driving member 5 drives the burner body 1 to move in the direction of the driving member 5. In this embodiment, the specific control method for the rotation of the burner body 1 is as follows: In the initial state, that is, when the burner body 1 is supported by the second support member 62, by controlling any one of the driving members 5 in the plurality of driving assemblies 4 to be energized to generate magnetic force, the burner body 1 is driven to move onto the driving member 5, and the lowest point of the burner body 1 moves onto the first support member 61 in the driving assembly 4 opposite to the driving member 5; after a certain period of time, the driving member 5 is powered off and loses magnetic force, and at the same time, the driving member 5 in the driving assembly 4 at the 180° circumferential position thereof is powered on to generate magnetic force, driving the burner body 1 to move onto the driving member 5, and its lowest point is also located on the first support member 61 in the driving assembly 4 opposite to the driving member 5; after the same certain period of time, the driving member 5 is powered off and loses magnetic force, and the driving member 5 in the driving assembly 4 at the 360 / 2N angular position in its circumference is powered on to generate magnetic force, driving the burner body 1 to move onto the driving member 5, and its lowest point moves onto the first support member 61 in the driving assembly 4 opposite to the driving member 5; after a certain period of time, the driving member 5 is powered off and loses magnetic force, and the driving member 5 at the 180° circumferential position of the previous driving member 5 is powered on, driving the burner body 1 to move onto the driving member 5, and its lowest point is also located on the first support member 61 in the driving assembly 4 opposite to the driving member 5. In this way, the included angle between the next reciprocating motion and the previous reciprocating motion of the burner body 1 is 360 / 2N to realize the rotation of the burner on the bottom of the pot, where N is a non-zero natural number. When cooking is over and the power is turned off, the electromagnet of the driving member 5 loses magnetic force due to being powered off, and the suction force between the driving member 5, the burner body 1, the first support member 61, and the second support member 62 disappears. The first support member 61 and the second support member 62 gradually return to the initial state under the influence of gravity, and the burner body 1 also returns to the balanced state supported by the second support member 62.

[0037] Furthermore, the driving member 5 is made of a metal material, and the support assembly 6 is made of a high-temperature resistant material. Its design is reasonable and ingenious, and the service performance of the product can be maintained stable for a long time.

[0038] Specifically, a plurality of recessed portions are provided on the tray 2 , and the first support member 61 , the second support member 62 and the driving member 5 are arranged inside the recessed portions. The structure is simple and compact, and the stability of the installation of the driving assembly 4 can be further improved.

[0039] In this embodiment, the driving member 5 is made of metal material to better promote the rotation of the burner, and can be stainless steel, or other more suitable materials can be selected according to actual needs. The support assembly is made of high temperature resistant material to improve the reliability of supporting the burner body 1, and the high temperature resistant material is non-ferrous. Of course, other more suitable materials can be selected according to actual needs. In this embodiment, a plurality of recessed parts are provided on the tray 2, and the first support member 61, the second support member 62 and the driving member 5 are arranged in the recessed parts. The driving member 5 does not rotate when the burner body 1 moves. Since the center of gravity of the first support member 61 and the second support member 62 is located directly below the center of its plane, when the burner body 1 moves, the first support member 61 and the second support member 62 only slightly deviate to simultaneously assist the movement of the burner body 1. In addition, in order to avoid large friction between the burner body 1 and the driving assembly 4 when the burner body 1 moves, a recess with a certain arc is provided at the bottom of the burner body 1 and the position where the driving assembly is connected.

[0040] Preferably, it also includes a connecting pipe 7 and a nozzle 8, which are arranged on the burner body 1 close to its center. One end of the connecting pipe 7 is connected to the nozzle 8, and the other end is used to connect to the air supply pipeline. Its structure is simple and compact.

[0041] In particular, the connecting pipe 7 is retractable and reasonably designed, and can supply gas normally while the burner body 1 rotates.

[0042] In this embodiment, a connecting pipe 7 and a nozzle 8 are also included. The connecting pipe 7 and the nozzle 8 are arranged at the middle position of the burner body 1. The connecting pipe 7 has internal and external threads, and the nozzle 8 has an internal thread that matches the external thread of the connecting pipe 7 so that one end of the connecting pipe 7 is connected to the nozzle 8 through threads, and the connecting pipe 7 and the nozzle 8 can move synchronously with the burner body 1. Since the connecting pipe 7 and the nozzle 8 are located near the center of the burner body 1, they do not interfere with the first support member 61 during the movement. The other end of the connecting pipe 7 is connected to the gas supply pipeline so that the gas supply pipeline supplies gas to the nozzle 8. In this embodiment, the connecting pipe 7 is retractable, and a spring tube can be connected to the connecting pipe 7 to make the gas supply pipeline retractable. Of course, other more suitable structures can also be used to meet the normal gas supply when the burner body 1 rotates. During the rotation of the burner body 1, the connecting pipe 7 drives the gas supply pipeline to be linked. Since the position of the gas supply pipeline is close to the center of the burner body 1, the length of the gas supply pipeline entering and exiting the panel does not change much, and it can be retracted and retracted up and down the panel hole without being affected.

[0043] Embodiment 2:

[0044] As Figures 1 to 3 shown, a cooking appliance includes a rotatable burner as described in Embodiment 1.

[0045] In this embodiment, the cooking appliance has a fully upward air intake combustion. It may include a rotatable burner as described in Embodiment 1. By rotatably arranging the burner body 1 on the cooking appliance panel, a cookware is placed above the burner body 1 so that the burner body 1 heats the cookware for cooking. By driving the burner body 1 to rotate, the burner body 1 serves as the active moving party in the relative movement between the pot and the fire, heating different areas of the bottom of the pot, so as to rotate the cookware during cooking to make the food heated evenly. In addition, it can also effectively improve the utilization rate of heat.

[0046] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
