Abstract
Description
Technical Field
[0001] This utility model relates to the field of stoves, and in particular to a burner cap and burner. Background Technology
[0002] During cooking, when the pot overflows or there is residual liquid at the bottom (especially when the pot is pointed), the overflowing or residual liquid will flow down the sides of the pot to the bottom, resulting in a dripping phenomenon.
[0003] Because the overflowing liquid has a centripetal velocity when it flows and detaches from the bottom of the pot, it will cause the liquid to splash towards the inner ring burner cap during the dripping process. In the prior art, the inner ring burner holes are usually set on the radial outer wall of the inner ring burner cap and tilted upwards. Therefore, the burner holes of the inner ring burner cap are in a welcoming position. When the overflow occurs, the overflowing liquid comes into direct contact with the flame and the burner holes, which may extinguish the flame or cause the overflowing liquid to enter the burner holes, leading to the risk of the burner holes being blocked.
[0004] Furthermore, since the inner ring flame hole is located on the radially outer side of the inner ring flame cap, the ignition needle and thermocouple can only be located on the outer periphery of the inner ring flame cap. Although there is a corresponding anti-clogging cap design to prevent the ignition needle and thermocouple from being contaminated, the anti-clogging cap extends from the outer periphery of the inner ring flame cap towards the radially outer side of the inner ring flame cap, while the dripping liquid flows from the radially outer side of the inner ring flame cap towards the radially inner side. That is, the dripping direction of the dripping liquid is opposite to the design direction of the anti-clogging cap. Therefore, the overflow or residual liquid will still drip onto the ignition needle and thermocouple, causing contamination of the ignition needle and thermocouple head, affecting ignition and flame preservation. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the defects in the prior art and provide a flame cap and burner.
[0006] The present invention solves the above-mentioned technical problems through the following technical solution:
[0007] A flame cap, the flame cap including an inner ring flame cap, the inner ring flame cap including an inner ring flame cap body and an inner ring flame hole, the inner ring flame cap body having an annular structure, the inner ring flame hole being disposed on the radial inner sidewall of the inner ring flame cap body, and the ignition needle and thermocouple being disposed on the radial inner side of the inner ring flame cap body.
[0008] The inner ring flame cap further includes a first groove, which is formed by the radially inner side of the inner ring flame cap body recessing towards the radially outer side of the flame cap. The upper end of the first groove is closed and the lower end is open, and the ignition needle can be at least partially accommodated in the first groove; and / or, the inner ring flame cap further includes a second groove, which is formed by the radially inner side of the inner ring flame cap body recessing towards the radially outer side of the flame cap. The upper end of the second groove is closed and the lower end is open, and the thermocouple can be at least partially accommodated in the second groove.
[0009] In this design, the inner ring flame holes are located on the radially inner sidewall of the inner ring flame cap body, ensuring that the flame outlets face the radially inner side of the inner ring flame cap body, in the same direction as the overflow. This prevents the overflow from directly impacting the inner ring flame and the inner ring flame holes, thus preventing the inner ring flame from extinguishing and the inner ring flame holes from becoming clogged. The ignition needle and thermocouple are located radially inner on the inner ring flame cap body, in the same direction as the overflow, and the inner ring flame cap also shields the ignition needle and / or thermocouple, better preventing the tops of the ignition needle and thermocouple from being contaminated by the overflow, ensuring their normal operation.
[0010] Preferably, the inner ring flame cap further includes a baffle plate, which is disposed above the inner ring flame hole and extends from the radially inner side of the inner ring flame cap body toward the radially inner side of the inner ring flame cap body.
[0011] In this design, the baffle plate is used to block the outlet of the inner ring flame hole, further preventing spillage from falling directly into the inner ring flame hole, preventing the inner ring flame from going out, and preventing the inner ring flame hole from becoming blocked.
[0012] Preferably, the baffle plate has an annular structure, and the radially outer side of the baffle plate abuts against the radially inner side of the inner ring fire cover body.
[0013] In this design, the annular baffle is easy to manufacture and can effectively block all inner ring fire holes.
[0014] Preferably, the upper surface of the baffle plate is flush with the upper surface of the inner ring fire cover body.
[0015] In this design, the above-mentioned arrangement avoids the inner ring flame being affected by the excessively short distance between the baffle plate and the inner ring flame hole.
[0016] Preferably, the flame cover further includes an outer ring flame cover and a drain groove. The outer ring flame cover is sleeved on the radially outer side of the inner ring flame cover. The drain groove is located radially between the inner ring flame cover and the outer ring flame cover, and the drain groove extends through both ends of the flame cover in the axial direction.
[0017] In this design, the drain trough is used to drain the overflow, preventing it from accumulating between the inner and outer ring burner caps and facilitating cleaning.
[0018] Preferably, the inner ring flame cap and the outer ring flame cap are integrally formed, and the flame cap further includes a connecting section disposed between the inner ring flame cap and the outer ring flame cap. The two ends of the connecting section in the radial direction of the flame cap are respectively connected to the lower end of the inner ring flame cap and the lower end of the outer ring flame cap, and the drain groove is disposed in the connecting section.
[0019] In this design, the overflow liquid that falls on the radially outer side of the inner ring burner and the radially inner side of the outer ring burner slides down under the action of gravity and is discharged through the drainage trough.
[0020] Preferably, the radially outer surface of the inner ring flame cap body is an inclined surface, and the radially outer surface of the inner ring flame cap body is inclined from top to bottom toward the radially outer side of the flame cap.
[0021] In this design, the above-mentioned arrangement allows the overflow liquid falling on the radially outer surface of the inner ring fire cap to flow into the drainage trough under the guidance of the inclined surface, facilitating better discharge of the overflow liquid.
[0022] Preferably, the radially inner surface of the outer ring flame cap is an inclined surface, and the radially inner surface of the outer ring flame cap is inclined from top to bottom toward the radially inner side of the flame cap.
[0023] In this design, the above-mentioned arrangement allows the overflow liquid falling on the radial inner side of the outer ring flame cap to flow into the drainage trough under the guidance of the inclined surface, facilitating better discharge of the overflow liquid.
[0024] Preferably, the top end of the radial inner wall of the drain trough is located below the top end of the radial outer wall of the drain trough, and the radial inner side of the outer ring flame cap partially overlaps with the drain trough along the axial direction of the flame cap in the projection of the outer ring flame cap onto the drain trough.
[0025] In this solution, the above-mentioned arrangement is used to prevent overflow from falling into the drain trough from the radial outer side of the inner ring flame cap and splashing back onto the top of the drain trough, thus ensuring better drainage of the overflow.
[0026] A burner comprising a flame cap as described above.
[0027] The significant advantages of this invention are as follows: the inner ring flame holes are located on the radially inner sidewall of the inner ring flame cap body, ensuring that the flame outlets face the radially inner side of the inner ring flame cap body, in the same direction as the overflow. This prevents the overflow from directly impacting the inner ring flame and the inner ring flame holes, thus preventing the inner ring flame from extinguishing and the inner ring flame holes from becoming clogged. The ignition needle and thermocouple are located radially inner on the inner ring flame cap body, in the same direction as the overflow, and the inner ring flame cap acts as a shield for the ignition needle and / or thermocouple, better preventing the tops of the ignition needle and thermocouple from being contaminated by the overflow, ensuring their normal operation.

[0046] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.
[0047] like Figure 1 As shown, this embodiment discloses a burner, including a burner cap, an ignition needle (not shown in the figure), and a thermocouple (not shown in the figure).
[0048] like Figure 1 and Figure 2 As shown, the flame cap includes an inner ring flame cap 1, which includes an inner ring flame cap body 11, an inner ring flame hole 12, a first groove 13, a second groove 14, and a baffle plate 15.
[0049] Specifically, such as Figures 1-4 As shown, the inner ring burner cap body 11 has a ring structure, and the inner ring flame holes 12 are located on the radial inner sidewall of the inner ring burner cap body 11. The inner ring flame holes 12 are inclined from bottom to top towards the radial inner side of the burner cap, and the flame outlet of the inner ring flame holes 12 penetrates the radial inner sidewall of the inner ring burner cap body 11. The inner ring flame is sprayed towards the center of the burner cap. Since the overflow liquid flows along the bottom of the pot from the radial outer side of the burner cap towards the radial inner side of the burner cap, the extension direction of the inner ring flame holes 12 and the spray direction of the inner ring flame are the same as the flow direction of the overflow liquid. The overflow liquid will not directly face the inner ring flame and the inner ring flame holes 12, thereby preventing the inner ring flame from going out and preventing the inner ring flame holes 12 from becoming blocked.
[0050] like Figure 1 and Figure 2 As shown, the radially inner side 111 of the inner ring flame cap body is recessed towards the radially outer side of the flame cap to form a first groove 13 and a second groove 14. The first groove 13 and the second groove 14 are spaced apart along the circumference of the flame cap. Both the first groove 13 and the second groove 14 are structures that are closed at the upper end and open at the lower end, that is, the first groove 13 and the second groove 14 have an upper end wall, and the lower ends of the first groove 13 and the second groove 14 penetrate through the lower wall surface of the inner ring flame cap body 1.
[0051] In this embodiment, since the inner ring flame hole 12 is located on the radially inner sidewall of the inner ring flame cap 1 body, the ignition needle and thermocouple are also located radially inner to the inner ring flame cap body 11. The ignition needle is at least partially accommodated in the first groove 13, and the thermocouple is at least partially accommodated in the second groove 14. The upper wall of the first groove 13 can shield the head of the ignition needle, preventing it from being contaminated by overflow liquid. The upper wall of the second groove 14 can shield the head of the thermocouple, preventing it from being contaminated by overflow liquid. Furthermore, since the ignition needle and thermocouple are located radially inner to the inner ring flame cap body 11, in the same direction as the overflow liquid flow, contamination of the ignition needle and thermocouple can be further prevented.
[0052] In other alternative embodiments, the first groove 13 and / or the second groove 14 may not be provided on the inner ring flame cap 1 body. A similar anti-blocking brim structure to the prior art can also be used to protect the ignition needle and / or thermocouple. This embodiment uses the form of the first groove 13 and the second groove 14 to protect the ignition needle and thermocouple in order to avoid the anti-blocking brim structure occupying the space at the center of the inner ring flame cap 1 body, thus ensuring the area of the inner ring flame.
[0053] like Figure 1 and Figure 2 As shown, a baffle plate 15 is disposed above the inner ring flame hole 12, extending from the radially inner side 111 of the inner ring flame cap body towards the radially inner side of the inner ring flame cap body 11. The baffle plate 15 is used to block the flame outlet of the inner ring flame hole 12, further preventing overflow liquid from falling directly into the inner ring flame hole 12, preventing the inner ring flame from going out, and preventing the inner ring flame hole 12 from becoming blocked.
[0054] Specifically, such as Figure 1 and Figure 2 As shown, the baffle plate 15 has a ring-shaped structure, with its radially outer surface abutting against the radially inner surface 111 of the inner ring flame cap body. The ring-shaped baffle plate 15 is easy to manufacture and can effectively block all the inner ring flame holes 12. Furthermore, the upper end face of the baffle plate 15 is flush with the upper end face of the inner ring flame cap body 11, preventing the distance between the baffle plate 15 and the inner ring flame holes 12 from being too short and affecting the inner ring flame.
[0055] In other alternative embodiments, the baffle 15 may also be divided into multiple baffle 15 units spaced apart in the circumferential direction of the flame cap, so as to cover all the inner ring flame holes 12 as much as possible.
[0056] like Figure 1 As shown, the flame cover also includes an outer ring flame cover 2, which is sleeved on the radially outer side of the inner ring flame cover 1. The outer ring flame hole 21 is provided on the radially outer side wall of the outer ring flame cover 2. In this embodiment, the inner ring flame cover 1 and the outer ring flame cover 2 are integrally formed. The inner ring flame cover 1 and the outer ring flame cover 2 are connected in the radial direction of the flame cover by a connecting section 4. The two ends of the connecting section 4 in the radial direction of the flame cover are respectively connected to the lower end of the inner ring flame cover 1 and the lower end of the outer ring flame cover 2.
[0057] like Figures 1-4 As shown, the burner cap also includes a drain trough 3, which is radially positioned between the inner ring burner cap 1 and the outer ring burner cap 2. Specifically, it is located on the connecting section 4, with both ends of the drain trough 3 penetrating the connecting section 4 in the axial direction. Overflowing liquid falling on the radially outer surface of the inner ring burner cap 1 and the radially inner surface 22 of the outer ring burner cap slides down onto the connecting section 4 under gravity and is discharged through the drain trough 3 on the connecting section 4, preventing overflow from accumulating between the inner ring burner cap 1 and the outer ring burner cap 2 and facilitating cleaning.
[0058] Furthermore, the radially outer surface 112 of the inner ring burner body is a slope, sloping downwards towards the radially outer side of the burner. Similarly, the radially inner surface 22 of the outer ring burner is a slope, sloping downwards towards the radially inner side of the burner. The radially outer surface of the inner ring burner 1, the radially inner surface 22 of the outer ring burner, and the upper end face of the connecting section 4 form an inverted cone shape to prevent overflow from the burner from being discharged outwards and away from the inner ring burner hole 12. Overflow from the radially outer surface of the inner ring burner 1 and the radially inner surface 22 of the outer ring burner can flow into the drainage trough 3 under the guidance of the slope, facilitating better drainage. The sloping design of the radially outer surface of the inner ring burner 1 also prevents splashing contamination from overflow at the outer ring burner 2.
[0059] Furthermore, such as Figure 2 As shown, in this embodiment, there are multiple drainage troughs 3, which are spaced apart along the circumference of the flame cover to ensure that the overflow from each place can be discharged in a timely manner.
[0060] like Figure 4 As shown, the top of the radial inner wall of the drain trough 3 is located below the top of the radial outer wall of the drain trough 3. The projection of the radial inner side 22 of the outer ring flame cap along the axial direction of the flame cap onto the drain trough 3 partially overlaps with the drain trough 3. That is, the radial inner side wall of the outer ring flame cap 2 partially blocks the upper opening of the drain trough 3 to prevent the overflow liquid falling into the drain trough 3 from the radial outer side of the inner ring flame cap 1 from splashing back onto the top of the drain trough 3, thus ensuring better drainage of the overflow liquid.
