By arranging at least one burner on the panel, cooking efficiency can be improved and cooking needs of users can be met.
[0042] 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 A schematic structural 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 hot melt component 31 provided in this embodiment. Figure 1-Figure 4 As shown, in order to reduce the safety hazard caused by backfire of 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 hot melt component 31 and a reset component 32. The hot melt component 31 is detachably arranged on the air flap 13 and can be clamped in the shift slot 21. The hot melt component 31 is configured to melt when the temperature at the air flap 13 reaches a preset temperature, and the two ends of the reset component 32 are respectively connected to the air flap 13 and the shift plate 2.
[0043] 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. When the preset temperature is reached, the hot melt 31 melts. At this time, the air flap 13 can rotate under the reset action of the reset member 32 to make the first air inlet 23 and the second air inlet 131 misaligned, 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 the backfire of the stove, and ensuring the safety of the stove. After the backfire phenomenon ends, the user can reinstall a new hot melt 31 on the air flap 13, and adjust the air flap 13 as needed to make the hot melt 31 snap into the shift slot 21 of the shift plate 2.
[0044] Continue as Figure 4 As shown, the hot melt 31 is connected to the air flap 13, the connection is stable, and it is convenient to disassemble. Specifically, the air flap 13 is provided with a connecting clamping protrusion 132, and the hot melt 31 is provided with a connecting clamping slot, and the connecting clamping protrusion 132 can be connected to the connecting clamping slot.
[0045] In this embodiment, the hot melt component 31 is a flexible sheath, and the sheath hole of the flexible sheath forms the above-mentioned connecting card slot. This arrangement can facilitate the user to replace the hot melt component 31. When the user installs the hot melt component 31, the hot melt component 31 can be deformed to adapt to the shape of the connecting card protrusion 132, and can be closely matched with the connecting card protrusion 132 under the action of its own elastic restoring force.
[0046] The present embodiment does not limit the material of the hot melt component 31, as long as the hot melt component 31 is structurally reliable at room temperature, can be stably engaged with the shift slot 21, and has a melting point below 200°C, it can be used. For example, the hot melt component 31 can be made of rubber. The preset temperature in the present embodiment is the melting point temperature of the hot melt component 31.
[0047] Figure 7 A schematic side view of the burner provided in this embodiment when no flashback occurs is shown. Figure 8 Shows Figure 7 A partial enlarged view at point A. Figure 7-Figure 8As shown, the hot melt component 31 is interference-fitted in the shift slot 21 to ensure the stability of the connection between the hot melt component 31 and the shift plate 2, preventing the hot melt component 31 from falling out of the shift slot 21 when the user is using the cooker, thereby affecting the cooking efficiency.
[0048] Continue as Figure 5 and Figure 6 As shown, in 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 elastic restoring force of the spring is relatively large, the material is convenient to obtain, and the manufacturing cost is low. 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.
[0049] Fig. 9 The schematic diagram of the structure of the burner provided in this embodiment when no flashback occurs is shown. Figure 2 .like Fig. 9 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. When the preset temperature is reached, the hot melt member 31 melts. 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, and the air intake is reduced, so that the flame resumes normal combustion, reduces the safety hazards caused by the stove backfire, and ensures 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.
[0050] 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.
