By arranging at least one burner on the panel, cooking efficiency can be improved and cooking needs of users can be met.

[0045] Figure 1 An explosion diagram of the burner provided in this embodiment is shown. Figure 2 A schematic structural diagram of the burner provided in this embodiment is shown. Figure 3 The structure diagram of the shift plate 2 provided in this embodiment is shown; Figure 4 FIG. 1 shows a schematic diagram of the structure of the air flap 13 and the thermally induced deformation member 31 provided in this embodiment. Figure 1-Figure 4As shown, in order to reduce the potential safety hazard caused by backfire in the stove, the present embodiment further provides a burner, which includes a burner assembly 1, a shift plate 2 and a backfire protection assembly 3. The burner assembly 1 includes a burner body 11, a valve body 12 and an air flap 13. The air flap 13 is rotatably arranged at the inlet of the burner body 11, and the nozzle of the valve body 12 passes through the air flap 13 and is connected with the inlet of the burner body 11; the shift plate 2 is arranged between the air flap 13 and the inlet of the burner body 11, and a shift slot 21 is arranged on the shift plate 2; the backfire protection assembly 3 includes a thermally induced deformation member 31 and a reset member 32. The thermally induced deformation member 31 is arranged on the air flap 13 and can be clamped in the shift slot 21. The thermally induced deformation member 31 can sense the temperature change at the air flap 13, and can be deformed to escape from the shift slot 21 when the backfire temperature is sensed, and the two ends of the reset member 32 are respectively connected to the air flap 13 and the shift plate 2.

[0046] Figure 5 The schematic diagram of the structure of the burner provided in this embodiment when no flashback occurs is shown. Figure 1 . Figure 6 FIG. 2 shows a schematic diagram of the structure of the burner provided in this embodiment when flashback occurs. Figure 5-Figure 6 Combined with Figure 3 and Figure 4 As shown, the shift plate 2 is provided with an arc-shaped first air inlet 23, and the air flap 13 is provided with an arc-shaped second air inlet 131. When the user uses the stove normally, the first air inlet 23 and the second air inlet 131 are directly opposite to each other to ensure that the inlet of the burner body 11 has sufficient air intake. When the stove backfires, the temperature at the air flap 13 rises, and the heat-sensing deformation member 31 senses the backfire temperature and deforms to escape from the shift slot 21 of the shift plate 2. At this time, the air flap 13 can rotate under the resetting action of the resetting member 32 to misalign the first air inlet 23 and the second air inlet 131, thereby reducing the air intake at the inlet of the burner body 11, and then restoring the flame to normal combustion, reducing the safety hazards caused by backfire of the stove, and ensuring the safety of the stove. After the tempering phenomenon ends, the temperature at the air flap 13 decreases, and the thermally induced deformable member 31 returns to its original state. The user can adjust the air flap 13 as needed to allow the thermally induced deformable member 31 to be re-engaged in the shift slot 21 of the shift plate 2.

[0047] Optionally, the thermally induced deformation member 31 is welded to the air flap 13 , which provides a stable connection and is convenient for processing.

Figure 7-10 As shown, the thermal induction deformable member 31 includes a first metal sheet 311 and a second metal sheet 312. The second metal sheet 312 is arranged on a side of the first metal sheet 311 close to the shift plate 2, and the thermal expansion coefficient of the second metal sheet 312 is greater than the thermal expansion coefficient of the first metal sheet 311. When the user uses the stove normally, the thermal induction deformable member 31 is in a straight state, and the thermal induction deformable member 31 is stuck in the shift slot 21 of the shift plate 2; when the stove is tempered, the temperature at the air flap 13 rises, the first metal sheet 311 and the second metal sheet 312 are deformed, and the thermal expansion coefficient of the second metal sheet 312 is greater than the thermal expansion coefficient of the first metal sheet 311, so that the thermal induction deformable member 31 bends toward the side away from the shift plate 2, so that the thermal induction deformable member 31 is disengaged from the shift slot 21 of the shift plate 2.

[0049] In one embodiment, the first metal sheet 311 includes a fitting portion 3111 and a clamping portion 3112 which are arranged at an angle and connected to each other. The fitting portion 3111 is connected to the air flap 13, and the second metal sheet 312 is fitted to the side of the fitting portion 3111 close to the shift plate 2. The clamping portion 3112 can be clamped with the shift slot 21. The structure is simple and convenient to process. By connecting the fitting portion 3111 and the clamping portion 3112 at an angle, the clamping portion 3112 can be easily clamped into the shift slot 21.

[0050] Fig.11 The schematic diagram of the structure of the thermally induced deformation member 31 provided in this embodiment is shown to be out of the gear slot 21. Fig.11 As shown, in another embodiment, the first metal sheet 311 includes a connecting fitting portion 3111 and a clamping portion 3112, the fitting portion 3111 is connected to the air flap 13, the second metal sheet 312 is attached to the fitting portion 3111 on one side close to the shift plate 2, and the clamping portion 3112 is provided with a clamping protrusion 3113 that can be clamped with the shift clamping slot 21. By providing the clamping protrusion 3113 on the clamping portion 3112, the clamping and disengagement of the thermally induced deformable member 31 and the shift clamping slot 21 can be achieved more conveniently.

[0051] In this embodiment, the second metal sheet 312 is bonded to the fitting portion 3111; or the second metal sheet 312 is welded to the fitting portion 3111, and the connection is stable and convenient for assembly. Of course, in other embodiments, the second metal sheet 312 and the fitting portion 3111 can also be connected in other ways, which are not limited in this embodiment.

[0052] Continue to refer to Figure 5In this embodiment, the reset member 32 is a spring, and the two ends of the spring are respectively connected to the air flap 13 and the shift plate 2. Among them, the spring has a large elastic restoring force, is easy to obtain, and has a low manufacturing cost. Specifically, the shift plate 2 and the air flap 13 are both provided with hooks, and the two ends of the spring are respectively hooked on the hooks of the shift plate 2 and the air flap 13, which is convenient for assembly and can improve assembly efficiency.

[0053] Fig.12 The schematic diagram of the structure of the burner provided in this embodiment when no flashback occurs is shown. Figure 2 .like Fig.12 As shown, in another embodiment, the reset member 32 includes a counterweight 321 and a connecting rope 322, one end of the connecting rope 322 is connected to the air flap 13, and the other end of the connecting rope 322 passes through the shift plate 2 and is connected to the counterweight 321. When the stove backfires, the temperature at the air flap 13 rises, and the heat-sensing deformable member 31 senses the backfire temperature and deforms to escape from the shift slot 21 of the shift plate 2. Under the gravity of the counterweight 321, the connecting rope 322 can pull the air flap 13 to rotate, so that the first air inlet 23 and the second air inlet 131 are misaligned, reducing the air intake, so that the flame resumes normal combustion, reducing the safety hazards caused by the stove backfire, and ensuring the safety of the stove. In this embodiment, the connecting rope 322 is a steel wire rope, the material cost of the steel wire rope is low, and it is strong and durable, which can extend the service life of the burner.

[0054] Optionally, a hanging ring 22 is provided on the shift plate 2, and the connecting rope 322 is passed through the hanging ring 22 and can slide relative to the hanging ring 22, thereby ensuring that the connecting rope 322 can smoothly pull the air flap 13 to rotate when the stove backfires, avoiding the connecting rope 322 from getting stuck when sliding relative to the shift plate 2.
