Description

Technical Field

[0001] The present invention relates to the technical field of stoves, in particular to a burner with an induction reliable ignition device. Background Art

[0002] Infrared burners are categorized as split or non-split types based on whether their combustion element can be disassembled. Non-split burners typically feature a single ignition pin because of their lower cost, fixed induction circuit, and improved reliability. As long as the gas between the ignition pin and the combustion plate is burning, the circuit remains connected. This allows accurate determination of gas combustion based on the circuit's continuity, resulting in increased safety.

[0003] The split combustion body is easy for users to remove and clean. If it is damaged, it is also convenient for after-sales personnel to replace only the combustion body without having to replace the entire burner. However, in order to ensure that the induction circuit is always in a conductive state when the flame is burning normally, the existing ignition needles of the split combustion body are all double needles. Because the two needles are placed directly above the flame, the gas burning between the needles can ensure that the circuit is in a conductive state, so that it can be accurately determined whether the gas is burning by the on-off of the circuit. However, the cost of double needles is high and they occupy more space, which is not suitable for areas with limited size. Split combustion bodies do not use single needles, because in the single needle solution, the combustion body and the burner are also part of the induction circuit, but the connection between the two is unreliable, which can easily cause the valve to be closed by misjudgment, thus affecting the normal use of the user.

[0028] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0029] Example 1

[0030] Infrared burner burners, due to their high operating temperatures, are typically made of cast iron or sheet metal. To improve corrosion resistance, cast iron burners are electrophoretically coated, while sheet metal burners are enameled. Both the electrophoretic and enameled layers are insulating and poorly conductive.

[0031] Regarding the ion sensing circuit: The burner head of an infrared burner is connected to the stove base, and the wire from the underside of the ignition pin passes through the stove controller and then connects to the stove base. For burners with an internal combustion element, as long as the internal combustion element and the burner are connected, the intermediate ions generated by the combustion of gas between the ignition pin and the internal combustion element can keep the entire induction circuit conductive. During normal use, since the internal combustion element is simply placed on the burner head and has an insulating layer on the burner head, the reliability of the induction circuit is primarily determined by the connection between the internal combustion element and the burner head.

[0032] See also Figure 1-3 This embodiment provides a burner with an induction-reliable ignition device, comprising a burner head 1, a combustion body assembly 2, a central through hole 3, and an ignition device (not shown). The burner head 1 is mounted within and abuts the stove bottom shell. The combustion body assembly 2 is positioned above the burner head 1 and covers the inner and outer mixing chambers 11 and 12. The central through hole 3 sequentially extends through the burner head 1 and the combustion body assembly 2. The ignition device comprises an ignition pin 4 and a bracket assembly 5. The ignition pin 4 is rotatably mounted within the central through hole 3 via the bracket assembly 5, with the upper end of the ignition pin 4 protruding from the upper end surface of the central through hole 3. The ignition pin 4 can be switched between a locked position and an unlocked position, and is electrically connected to a stove controller mounted within the stove bottom shell via a wire. The bracket assembly 5 is connected to the burner head 1 and comprises an elastic portion 501. The elastic portion 501 presses against the combustion body assembly 2 and can push the upper end of the bracket assembly 5 against the combustion body assembly 2.

[0033] In this embodiment, the ignition pin 4, cooker controller, bottom housing, burner 1, and combustion element assembly 2 form an induction circuit. The ignition device bracket assembly 5 indirectly connects the burner 1 and combustion element assembly 2, further improving the reliability of the connection between the burner 1 and combustion element assembly 2, thereby ensuring that the combustion element assembly 2 and the burner 1 are in a conductive state.

[0034] It can be seen that the burner of this embodiment has an ignition device with a simple structure and occupies a small space. It is connected to the burner head through the bracket assembly 5, and by providing an elastic portion 501 on the bracket assembly 5, when the elastic portion 501 is pressed tightly against the combustion body assembly 2, the elastic portion 501 can push the upper end of the bracket assembly 5 to abut the combustion body assembly 2, so that there are multiple reliable contact points between the bracket assembly 5 and the combustion body assembly 2, ensuring that the burner head 1 and the combustion body assembly 2 are in a reliable connection, further ensuring the reliability of the burner induction circuit, and reducing costs at the same time.

[0035] See also Figure 2-3 Specifically, the burner head 1 of this embodiment has an inner gas mixing chamber 11, an outer gas mixing chamber 12, and a middle gas mixing chamber 13 that are open upward, and the burner head 1 is provided with a lower center hole 101, which constitutes the lower portion of the central through hole 3. Correspondingly, the combustion body assembly 2 includes an inner combustion body assembly 21 and an outer combustion body assembly 22. The inner combustion body assembly 21 is provided above the inner gas mixing chamber 11 and abuts against the inner and outer annular walls of the inner gas mixing chamber 11 of the burner head 1 to ensure reliable contact between the inner combustion body assembly 21 and the burner head 1, thereby ensuring the reliability of the induction circuit. The outer combustion body assembly 22 is provided above the outer gas mixing chamber 12 and the middle gas mixing chamber 13 to form a middle ring fire and an outer ring fire when the gas burns above the outer combustion body assembly 22.

[0036] Preferably, the inner combustion body assembly 21 includes an inner combustion body 211 and an inner gas distribution plate 212. The inner combustion body 211 is an annular structure. The inner combustion body 211 can be detachably mounted on the inner gas distribution plate 212. This makes it convenient for users to remove the inner combustion body 211 for cleaning. If the inner combustion body 211 is damaged, it is convenient for users to only replace the combustion body without having to replace the entire burner. In addition, the inner gas distribution plate 212 is a metal part, and its cover is arranged above the inner mixing chamber 11 and abuts against the inner annular wall of the inner mixing chamber 11 to enhance the installation stability of the inner gas distribution plate 212 and ensure that the inner gas distribution plate 212 is in reliable contact with the burner head 1. In addition, an upper center hole 201 is formed at the center of the inner gas distribution plate 212, and the upper center hole 201 constitutes the upper part of the central through hole 3.

[0037] More preferably, in order to ensure the reliability of the connection between the inner gas distribution plate 212 and the inner combustion body 211, the inner or outer side of the inner gas distribution plate 212 can fix the inner combustion body 211 therein by riveting or other means, so as to ensure a stable connection between the two and ensure electrical conductivity.

[0038] See also Figure 4-6 Specifically, the bracket assembly 5 includes a fixing seat 51 and a bracket 52. The fixing seat 51 is arranged in the central through hole 3 and is provided with an opening 511 for the ignition needle 4 to pass through. The bracket 52 is respectively connected to the burner 1 and the fixing seat 51. The elastic part 501 is arranged on the bracket 52 and is tightly pressed against the combustion body assembly 2, that is, the elastic part 501 abuts against the lower end of the inner side wall of the upper central hole 201 of the inner gas distribution plate 212, and the elastic part 501 can push the fixing seat 51 to abut against the gas distribution plate of the combustion body assembly 2, that is, The elastic portion 501 can push the fixing base 51 against the upper end of the inner side wall of the upper center hole 201 of the inner gas distribution plate 212. In this way, through the bracket 52 and the elastic portion 501 provided on the bracket 52, the bracket 52 and the elastic portion 501 are clamped on the two opposite inner side walls of the upper center hole 201, indirectly achieving a reliable connection between the burner head 1 and the inner gas distribution plate 212, further strengthening the connection and abutment between the burner head 1 and the inner gas distribution plate 212, thereby ensuring the reliability of the induction circuit. Preferably, the fixing base 51 and the bracket 52 are both conductive metal parts to ensure the conductive effect.

[0039] In this embodiment, the ignition needle 4 passes through the opening 511 and can be switched between a locked position and an unlocked position. In this way, when the ignition needle 4 is switched to the unlocked position, the ignition needle 4 can be rotated to the zero position. At this time, the inner combustion body assembly 21 can be removed for user cleaning and reinstalled into the burner head 1 after cleaning; when the ignition needle 4 is switched to the locked position, the ignition needle 4 can no longer be rotated, ensuring that the ignition needle 4 is installed stably and reliably, and the burner can be used normally at this time.

[0040] See also Figure 4-6 In this embodiment, the ignition needle 4 includes a needle body 41 and an insulating housing 42. The upper end of the needle body 41 is located above the inner combustion body assembly 21. A limiting protrusion 401 is provided on the outer wall of the ignition needle 4 (i.e., the outer wall of the insulating housing 42) at a position corresponding to the opening 511. A circumferentially arranged sliding groove 5111 is provided on the inner wall of the opening 511. The length of the sliding groove 5111 is less than the circumference of the upper end surface of the opening 511. The limiting protrusion 401 is rotatably disposed within the sliding groove 5111. In addition, at least two positioning grooves 402 are provided at intervals on the outer side wall of the limiting protrusion 401 or the ignition needle 4 (i.e., the insulating shell 42), and a positioning protrusion 5112 is provided on the inner side wall of the opening 511 below the slide groove 5111. The positioning protrusion 5112 selectively engages with one of the positioning grooves 402. In this way, the ignition needle 4 is locked by cooperating with the positioning protrusion 5112 and one of the positioning grooves 402. At this time, the ignition needle 4 is in a locked position.

[0041] See also Figure 1 、 Figure 4 and Figure 7-8Preferably, the bracket 52 includes a first mounting plate 521 and a support plate 522. The first mounting plate 521 is arranged at the lower end of the support plate 522 and connected to the burner 1. The upper end of the support plate 522 is connected to the fixing seat 51. One end of the elastic portion 501 is connected to the side of the support plate 522 facing away from the ignition needle 4, and the other end faces and abuts the gas distribution plate. In this embodiment, the first mounting plate 521 is integrally formed and arranged at the lower end of the support plate 522. The support plate 522 and the first mounting plate 521 form an "L" shape to ensure a reliable connection between the first mounting plate 521 and the support plate 522, while saving the assembly process between the two. Figure 1 During installation, the first mounting plate 521 is fastened to the bottom of the furnace head 1 by screws 8, thereby effectively ensuring the reliability and stability of the connection between the first mounting plate 521 and the furnace head 1, and ensuring that the first mounting plate 521 and the furnace head 1 can be conductive.

[0042] More preferably, the elastic portion 501 is an elastic sheet similar to an "L" shape to ensure that the elastic portion 501 has a sufficiently large elastic force. The bracket 52 is provided with an opening 502 at the position corresponding to the inner gas distribution plate 212 of the combustion body assembly 2. The elastic sheet is arranged at the opening 502 and its upper end is integrally formed with the support plate 522, and its lower end faces and abuts the inner gas distribution plate 212. In this way, by designing the elastic sheet to be integrally formed with the support plate 522, not only the connection reliability and stability of the elastic portion 501 and the support plate 522 are improved, but also the elastic portion 501 can be quickly processed and formed, thereby improving the utilization rate and practicality of the support plate 522. Figure 8 When one end of the elastic sheet away from the support plate 522 abuts against the lower end of the inner wall of the upper center hole 201 of the inner gas distribution disk 212, the elastic sheet can push the fixing seat 51 to move in the opposite direction of the elastic sheet through the support plate 522, so that the fixing seat 51 is tightly abutted against the upper end of the inner wall of the upper center hole 201, and then the fixing seat 51 is clamped between the bracket 52 and the inner wall of the upper center hole 201 of the inner gas distribution disk 212, further improving the connection reliability of the fixing seat 51 and the inner gas distribution disk 212.

[0043] In addition, a press profile 505 is provided at the lower end of the support plate 522 along its length direction. The press profile 505 is located below the opening 502 to enhance the strength of the support plate 522 .

[0044] See also Figure 4 and Figure 7 More specifically, the bracket 52 further includes a second mounting plate 523, which is disposed at the upper end of the support plate 522 and faces the fixing base 51. The fixing base 51 is connected to the support plate 522 via the second mounting plate 523. Thus, the second mounting plate 523 provides a reliable connection between the support plate 522 and the fixing base 51, increases the connection area between the two, and improves the connection strength.

[0045] Preferably, an outwardly extending boss 512 is provided at the upper end of the outer wall of the fixing base 51, a downwardly extending positioning post 5121 is provided at the bottom of the boss 512, and the second mounting plate 523 is provided with a positioning hole 503 adapted to engage with the positioning post 5121. The positioning post 5121 is inserted into the positioning hole 503, and the top surface of the second mounting plate 523 abuts the bottom surface of the boss 512. Thus, through the engagement of the positioning post 5121 with the positioning hole 503, and the support and abutment of the top surface of the second mounting plate 523 against the boss 512, the fixing base 51 is ensured to be securely and reliably mounted on the second mounting plate 523 of the bracket 52, further enhancing the reliable connection between the fixing base 51 and the bracket 52.

[0046] More preferably, the second mounting plate 523 is provided with a snap-in groove 504 opening toward the fixing seat 51, and the snap-in groove 504 is snap-fitted to the outer surface of the fixing seat 51, thereby increasing the reliable connection area between the second mounting plate 523 and the fixing seat 51. In this embodiment, the second mounting plate 523 and the upper end of the support plate 522 are formed so that the second mounting plate 523 and the support plate 522 are in a stable and reliable connection, and the second mounting plate 523, the support plate 522 and the first mounting plate 521 form a "Z" shape with each other. In this way, when the elastic portion 501 is pressed tightly against the lower end of the inner ring wall of the inner gas distribution disk 212, it can push the second mounting plate 523 to move in the direction opposite to the elastic portion 501, thereby pushing the fixing seat 51 to be tightly pressed against the upper end of the inner ring wall of the inner gas distribution disk 212.

[0047] In other embodiments, the fixing seat 51 can be fastened to the second mounting plate 523 or the support plate 522 of the bracket 52 by welding, riveting, etc. When the fixing seat 51 is fastened to the second support plate 522 of the bracket 52, it not only ensures that the fixing seat 51 and the bracket 52 are reliably connected, but also the second mounting plate 523 can be omitted, which is conducive to reducing manufacturing costs.

[0048] See also Figure 4-6 When the ignition needle 4 is switched to the unlocked position, the ignition needle 4 can move along the slide groove 5111. When the needle body 41 of the ignition needle 4 rotates to the maximum position of the boss 512 of the fixing seat 51, the ignition needle 4 is in the zero position. At this time, the needle body 41 is located directly above the boss 512, and the inner combustion body assembly 21 can be removed for user cleaning, and reinstalled into the burner 1 after cleaning.

[0049] See also Figure 4 and Figure 8Furthermore, the assembly further includes a stopper 6 and an elastic member 7. The stopper 6 is disposed on the outer wall of the insulating housing 42 of the ignition needle 4 and is located below the fixing seat 51. The elastic member 7 is sleeved on the outer surface of the ignition needle 4, with the upper and lower ends of the elastic member 7 respectively abutting the fixing seat 51 and the stopper 6. Thus, by disposing the elastic member 7 between the stopper 6 and the fixing seat 51, a restoring force is provided when the ignition needle 4 is pulled up, thereby facilitating the rapid removal of the ignition needle 4.

[0050] Preferably, the limiting member 6 of this embodiment is a C-shaped snap ring, and the elastic member 7 is a spring. Figure 6 A groove 403 arranged along the circumferential direction is provided on the outer wall of the insulating shell 42, and the C-shaped clamping ring is engaged with the groove 403, thereby achieving the fixation of the limit member 6.

[0051] Example 2

[0052] See also Figure 9 This embodiment differs from Example 1 in that the bracket 2 and elastic member 7 are fixed differently, and the position-limiting member 6 can be omitted. Specifically, the bracket 52 is provided with an extension 524 extending toward the ignition needle 4. The extension 524 has a slot for the ignition needle 4 to pass through, and the insulating housing 42 of the ignition needle 4 passes through the slot. The elastic member 7 is sleeved on the outer surface of the ignition needle 4, with its upper and lower ends respectively abutting the fixing seat 51 and the extension 524. The remaining components are identical to those of Example 1.

[0053] It can be seen that by providing an extension portion 524 with a slot on the bracket 52 and arranging the elastic member 7 between the extension portion 524 and the fixing seat 51, the utilization rate of the bracket 52 is further improved, and the limiting member 6 is omitted, so that the manufacturing cost is lower.

[0054] Example 3

[0055] See also Figure 10 The difference between this embodiment and embodiment 1 is that the structures of the burner head 1 and the combustion body assembly 2 are different. Specifically, the burner head 1 only has an inner gas mixing chamber 11 and an outer gas mixing chamber 12 that are open upward. Correspondingly, the combustion body assembly 2 is an outer combustion body assembly 22, and the outer combustion body assembly 22 is covered above the outer gas mixing chamber 12 and the inner gas mixing chamber 11, so that the gas forms an inner ring fire and an outer ring fire when burning above the outer combustion body assembly 22. In addition, the outer combustion body assembly 22 includes an outer combustion body 221 and an outer gas distribution plate 222, and the outer combustion body 221 is fixedly installed in the outer gas distribution plate 222, and the outer gas distribution plate 222 is covered above the outer gas mixing chamber 12 and the inner gas mixing chamber 11 and abuts the burner head 1. The elastic portion 501 is pressed tightly against the lower end of the inner ring wall of the outer gas distribution plate 222, and the elastic portion 501 can push the fixing seat 51 to tightly abut the upper end of the inner ring wall of the outer gas distribution plate 222.

[0056] It can be seen that by omitting the inner combustion body assembly 21 as described in Example 1, the reliability of the burner induction circuit is ensured while saving assembly steps, thereby lowering the manufacturing cost of the entire burner.

[0057] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
