Description

Technical Field

[0001] This utility model relates to the technical field of kitchen equipment, and in particular to a burner, stove and integrated stove. Background Technology

[0002] Existing burners can achieve independent ignition for each ring by independently supplying gas to its mixing chamber. However, existing burners struggle to ensure the stability of the flame in each ring. Typically, only a thermocouple is installed for a single ring to improve the ignition stability of that ring. With this structure, when ensuring stable ignition for multiple rings of the burner, a thermocouple needs to be provided for each ring separately. This increases the number of thermocouples required for the product, leading to higher production costs. Utility Model Content

[0003] Firstly, this utility model provides a burner to achieve the technical effect of providing stable ignition to multiple mixing chambers by installing a single thermocouple.

[0004] To achieve the above objectives, this utility model discloses a burner, including a mixing seat, a flame cap assembly, and a thermocouple. The mixing seat and the flame cap assembly are assembled to form multiple mixing chambers, each of which is connected to a flame hole. The characteristic feature is that at least two of the mixing chambers are provided with a flame stabilizing structure connected to them. The flame stabilizing structure includes several flame stabilizing channels. One end of each flame stabilizing channel is connected to the corresponding mixing chamber, and the other end faces the thermocouple. The flame outlet of each flame stabilizing channel can be used to heat the thermocouple.

[0005] Optionally, at least a portion of the flame stabilizing channels are distributed circumferentially along the burner, and / or at least a portion of the flame stabilizing channels are distributed vertically along the axial direction of the burner.

[0006] Optionally, one of the mixing chambers of the burner is a first mixing chamber, and the other mixing chamber is a second mixing chamber. The first mixing chamber is connected to a first flame port, and the second mixing chamber is connected to a second flame port. The burner also includes a first flame stabilizing structure connected to the first mixing chamber and a second flame stabilizing structure connected to the second mixing chamber. The thermocouple is placed between the flame outlet of the flame stabilizing channel of the first flame stabilizing structure and the flame outlet of the flame stabilizing channel of the second flame stabilizing structure.

[0007] Optionally, the flame cap assembly includes a first flame cap and a second flame cap. The first flame cap is located inside the inner ring of the second flame cap. The first flame cap and the mixing seat are assembled to form a first mixing chamber. The second flame cap and the mixing seat are assembled to form a second mixing chamber.

The flame stabilizing channel of the second flame stabilizing structure extends from the outside to the inside along the radial direction of the second flame cap. The flame stabilizing channel of the first flame stabilizing structure extends from the inside to the outside along the radial direction of the first flame cap.

[0008] Optionally, the flame cap assembly includes a second flame cap, which includes a second upper flame cap and a second lower flame cap. The second upper flame cap is provided with a second flame hole, and a third mixing chamber is formed between the side of the second lower flame cap opposite to the second upper flame cap and the mixing seat.

The burner cap assembly 2 is also arranged sequentially from the inside to the outside with a first flame hole 31, a second flame hole 32, and a third flame hole 33. Multiple first flame holes 31 are distributed along the circumference of the burner and are connected to the first mixing chamber 11. Multiple second flame holes 32 are distributed along the circumference of the burner and are connected to the second mixing chamber 12. Multiple third flame holes 33 are distributed along the circumference of the burner and are connected to the third mixing chamber 13.

[0018] To achieve independent flame preservation for the first flame port 31 and the second flame port 32, the burner also includes a first flame stabilizing structure 41 communicating with the first mixing chamber 11 and a second flame stabilizing structure 42 communicating with the second mixing chamber 12. Each flame stabilizing structure includes a flame stabilizing channel connecting the mixing chamber and the outside. Thermocouple 6 is placed between the flame outlet of the flame stabilizing channel of the first flame stabilizing structure 41 and the flame outlet of the flame stabilizing channel of the second flame stabilizing structure 42, and the flame outlets of the flame stabilizing channels of the first flame stabilizing structure 41 and the second flame stabilizing structure 42 are oriented towards the thermocouple 6. The flames from both the first flame stabilizing structure 41 and the second flame stabilizing structure 42 can be used to heat the thermocouple 6. Multiple flame stabilizing channels can be provided and distributed circumferentially along the burner. In addition, the flame stabilizing channels can also be distributed vertically along the axial direction of the burner. In other embodiments, the mixing chamber 1 and the burner cap assembly 2 may be assembled to form multiple or two mixing chambers, each mixing chamber being connected to a flame port. At least two mixing chambers are provided with a flame stabilizing structure connected to them. The flame stabilizing structure includes several flame stabilizing channels, one end of which is connected to the corresponding mixing chamber, and the other end of which faces the thermocouple 6. The flame outlet of each flame stabilizing channel can be used to heat the thermocouple 6.

The flame stabilizing channel of the first flame stabilizing structure 42 extends radially from the inside to the outside along the first flame cap 22 and penetrates the side wall of the first mixing chamber 11 on the side away from the center of the burner.

[0020] Reference Figure 2 and Figure 3 The first flame cap 21 has an upper half of the first mixing chamber 11, and the first flame holes 31 are distributed circumferentially along the outer peripheral wall of the first flame cap 21. The outer peripheral wall of the first flame cap 21 is inclined from top to bottom outwards, and the central axis of the first flame holes 31 is also inclined from inside to outside upwards.

[0021] The first flame cap 21 has multiple flame stabilization channels on the side near the thermocouple 6.

[0022] Multiple flame stabilizing channels are distributed and form a group within a section of the circumferential arc of the outer peripheral wall of the first flame cap 21. At the same time, two groups of flame stabilizing channels are distributed vertically on the outer peripheral wall of the first flame cap 21. In other embodiments, the flame stabilizing channels may be arranged in only one row along a section of arc, or more than two rows of flame stabilizing channels may be arranged vertically.

[0023] The outer peripheral wall of the first flame cap 21 is provided with multiple ignition holes 7 at positions symmetrical to the flame stabilization channel.

The upper inner ring surface 2212, the flame outlet surface 2211, and the upper outer ring surface 2213 constitute the upper part of the second mixing chamber 12.

[0026] The second flame hole 32 is distributed on the flame outlet surface 2211, and the second flame hole 32 extends from bottom to top along the central axis of the second upper flame cover 221.

[0027] Reference Figure 2 and Figure 4 The second lower burner cap 222 is annular and has an annular partition 2221, a lower inner ring surface 2222 connected to the inner ring of the partition 2221 and extending parallel to the central axis of the second lower burner cap 222, and a lower outer ring surface 2223 connected to the outer ring of the partition 2221 and extending parallel to the central axis of the second lower burner cap 222.

[0028] The second lower burner cap 222 forms a third mixing chamber 13 between the side opposite to the second upper burner cap 221 and the mixing seat 1. The upper part of the third mixing chamber 13 is located below the part of the partition 2221 near the outer ring. The third burner hole 33 is arranged in the lower half of the lower outer ring surface 2223 along the circumference of the second lower burner cap 222. The third burner hole 33 extends radially along the second lower burner cap 222, penetrates the lower outer ring surface 2223, and communicates with the third mixing chamber 13.

[0029] In this embodiment, the flame stabilizing channel of the second flame stabilizing structure 42 is located on the side of the lower inner ring surface 2222 near the thermocouple 6, and the central axis of the flame stabilizing channel is inclined upward from the outside to the inside. Multiple flame stabilizing channels of the second flame stabilizing structure 42 are arranged along an arc section of the lower inner ring surface 2222.

[0030] In other embodiments, the flame stabilizing channels of the second flame stabilizing structure 42 may also be arranged in multiple rows on the lower inner ring surface 2222, and the central axis of the flame stabilizing channels may also be parallel to the radial direction of the second lower flame cap 222.

[0031] In other embodiments, the flame stabilizing channel of the second flame stabilizing structure 42 may also be provided on the upper inner ring surface 2212, or the second flame stabilizing structure 42 may be provided on both the upper inner ring surface 2212 and the lower inner ring surface 2222.

[0032] The mixing base 1 comprises, from the inside out, the lower portion of the first mixing chamber 11, the lower portion of the second mixing chamber 12, and the lower portion of the third mixing chamber 13. A space is formed between the lower portions of the first mixing chamber 11 and the second mixing chamber 12 to accommodate the thermocouple 6 and the ignition needle 5. The thermocouple 6 and the ignition needle 5 are vertically positioned at the bottom of the mixing base 1. During assembly, the second lower burner cap 222 and the first burner cap 21 are placed above the mixing base 1, and the second upper burner cap 221 is placed above the second lower burner cap 222.

[0033] Thermocouple 6 is 415-6mm away from the first flame stabilizing structure, preferably 5mm away, and thermocouple 6 is 426-7mm away from the second flame stabilizing structure, preferably 7mm away.

[0034] Thermocouple 6 is connected to a solenoid valve located on the gas pipeline. When the flame heats thermocouple 6, a potential difference is formed. The change in temperature will change the magnitude of the potential difference. After the magnitude of the change in potential difference is passed through the controller, the controller outputs a corresponding control command to drive the valve body to open and close, so as to control the amount of gas output by the valve body according to the temperature and realize the continuous flame preservation function.

[0035] The mixing chamber 1 is provided with a first gas passage connected to the first mixing chamber 11, a second gas passage connected to the second mixing chamber 12, and a third gas passage connected to the third mixing chamber 13.
