Description

Technical Field

[0001] This utility model relates to a stove, and more particularly to a burner and a gas stove. Background Technology

[0002] The burner is a crucial component of a gas stove. During operation, a gas outlet is located on the top side of the burner. After the gas and air inside the burner mix, the mixture exits through the outlet towards the center of the burner and is ignited. To ensure efficient combustion, thorough mixing of the gas and air is essential. Currently, when gas and air enter the burner, they undergo initial mixing via an injector tube, and then further mixing as they flow through the outlet. However, at the outlet, the gas and air remain incompletely mixed, hindering further improvements in combustion efficiency. Therefore, a burner design that can significantly enhance the gas-air mixing effect is urgently needed. Utility Model Content

[0003] The purpose of this utility model is to provide a burner and a gas stove to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A burner includes: a bottom shell with a mixing groove on its top side, an ejector tube on the bottom side of the bottom shell communicating with the mixing groove; a ignition base connected to the mixing groove, a first gap forming between the bottom side of the ignition base and the bottom of the mixing groove, a second gap forming between the sidewall of the ignition base and the inner side of the mixing groove, the first gap and the second gap communicating with the ejector tube, a combustion groove on the top side of the ignition base, and a plurality of exhaust grooves surrounding the combustion groove on the top side of the ignition base, the extension directions of the plurality of exhaust grooves being respectively offset from the center of the mixing groove; and a top cover connected to the bottom shell, the top cover being located on the top side of the ignition base and covering the plurality of exhaust grooves.

[0006] This technical solution has at least the following beneficial effects: The ejector tube is used to connect to the gas and air supply pipe of the external device. When gas and air are supplied into the ejector tube, they are pre-mixed. Then, they pass through the first gap between the bottom side of the ignition base and the bottom of the mixing tank, and the second gap between the side wall of the ignition base and the inner side of the mixing tank. At this time, the gas mixture formed by the gas and air disperses and surrounds the outer periphery of the ignition base, and then enters into multiple outlet slots. The top cover blocks and seals the multiple outlet slots on the top side of the ignition base, which can ensure that the gas mixture flows along the multiple outlet slots and enters the combustion chamber. Since the extension direction of the outlet slots is deviated from the center of the mixing tank, the path of the gas mixture through the outlet slots can be extended, and the gas mixture forms a rotating airflow when it enters the combustion chamber, which strengthens the contact and mixing with the air in the combustion chamber and improves the combustion thermal efficiency. In this way, the gas mixture is discharged into the combustion chamber at an angle, forming a rotating airflow in the combustion chamber, which effectively improves the mixing of gas and air, thereby improving the utilization rate of gas and the combustion thermal efficiency.

[0007] As a further improvement to the above technical solution, a mixing mesh plate is sleeved on the outer side of the ignition base, and the mixing mesh plate covers multiple mixing slots.

[0008] As a further improvement to the above technical solution, an annular step is provided on the outer side of the bottom of the ignition, and the upper cover presses the mixing mesh plate against the annular step.

[0009] As a further improvement to the above technical solution, an air intake column is provided on the bottom side of the ignition base, and an air intake channel communicating with the combustion chamber is formed in the air intake column. Multiple air intake columns are arranged around the center of the ignition base, and connection holes are respectively provided on the bottom side of the bottom shell corresponding to the positions of the multiple air intake channels.

[0010] As a further improvement to the above technical solution, the bottom of the mixing tank is provided with protrusions corresponding to the positions of the multiple air intake columns, the multiple connecting holes are formed in the middle of the multiple protrusions, and the bottoms of the multiple air intake columns are respectively engaged with the multiple protrusions.

[0011] As a further improvement to the above technical solution, an arc-shaped protrusion is formed in the middle of the bottom of the combustion tank.

[0012] A gas stove includes: the burner described above; a stove body with an internal base support, the base support forming an upward-facing cavity, and a bottom shell connected to the center of the cavity; a windproof ring connected to the bottom side of the base support, the plane of the top side of the windproof ring being located below the plane of the top side of the base support; a bracket connected to the bottom side of the base support, the bracket having a rotatable support member, the top surface of the support member serving as a support surface, the support surface being rotatable downwards to enter the windproof ring or upwards to protrude from the windproof ring, and the bracket having multiple such members surrounding the windproof ring.

[0013] This technical solution has at least the following beneficial effects: the burner can ignite and heat inside the cavity; the sidewall of the base itself forms an outer ring within the cavity that can block wind and concentrate energy; the windproof ring is installed on the bottom side of the base and forms an inner ring within the base that can block wind and concentrate energy; in use, the boiler is placed on multiple supports, and the support members on the supports abut against the boiler to provide support; when the boiler is small, the multiple support members rotate downwards to enter the fireproof ring, and the boiler is pressed down to abut against the multiple support members. At this time, the multiple support surfaces are inclined against the outside of the boiler to provide limiting support, and the direct heat to the boiler can be increased through the support members themselves. The inner ring formed by the fireproof ring can directly block wind and concentrate energy around the boiler, effectively improving the boiler's heating efficiency. When the boiler is large, multiple support components rotate upwards until their support surfaces protrude beyond the fireproof ring. The boiler presses down on the multiple support components, at which point the multiple support surfaces abut against the bottom side of the boiler to provide support. The outer ring formed by the bottom support sidewall can block wind and concentrate energy around the boiler. In this way, the rotation of multiple support components can adapt to different boiler sizes, providing stable support for the boiler. Furthermore, the double-layer energy-concentrating structure of the inner and outer rings can provide a uniform heating environment for the boiler, which helps to reduce heat loss and improve heating efficiency.

[0014] As a further improvement to the above technical solution, the top of the bracket is provided with an arc-shaped convex corner on the side near the center of the base, and the bottom side of the support member is provided with a connecting groove. The arc-shaped convex corner is rotatably connected to the connecting groove. When the support member is rotated upward to protrude from the windproof ring, the bottom side of the support member abuts against the top side of the bracket.

[0015] As a further improvement to the above technical solution, the bracket has an upwardly protruding limiting part on the side away from the center of the base.

[0016] As a further improvement to the above technical solution, a limiting concave angle is provided at the apex of the limiting part near the center of the base.

[0030] Reference Figures 1 to 4 A burner includes a bottom shell 100, a flame distribution base 200, and a top cover 300. A mixing groove 110 is provided on the top side of the bottom shell 100, and an ejector tube 120 is provided on the bottom side of the bottom shell 100, the ejector tube 120 being connected to the mixing groove 110. The flame distribution base 200 is connected to the mixing groove 110, a first gap 210 is formed between the bottom side of the flame distribution base 200 and the bottom of the mixing groove 110, and a second gap is formed between the sidewall of the flame distribution base 200 and the inner side of the mixing groove 110. 220, the first gap 210 and the second gap 220 are interconnected with the ejector tube 120, a combustion groove 260 is provided on the top side of the ignition base 200, and a plurality of gas outlet grooves 230 are provided around the combustion groove 260 on the top side of the ignition base 200, and the extension direction of the plurality of gas outlet grooves 230 is respectively offset from the center of the mixing groove 110; the upper cover 300 is connected to the bottom shell 100, and the upper cover 300 is located on the top side of the ignition base 200 and covers the plurality of gas outlet grooves 230.

[0031] As described above, the ejector tube 120 is used to connect to the gas and air supply pipe of an external device. When gas and air are supplied into the ejector tube 120, they are pre-mixed. Then, through the first gap 210 between the bottom side of the ignition base 200 and the bottom of the mixing tank 110, and the second gap 220 between the side wall of the ignition base 200 and the inner side of the mixing tank 110, the gas mixture formed by the gas and air disperses and surrounds the outer periphery of the ignition base 200, and then enters into multiple gas outlet slots 230. The top cover 300 blocks and seals the multiple gas outlet slots 230 on the top side of the ignition base 200. The mixture is ensured to flow along multiple outlet channels 230 and enter the combustion chamber 260. Since the extension direction of the outlet channels 230 is deviated from the center of the mixing channel 110, the path of the mixture through the outlet channels 230 can be extended, and the mixture forms a rotating airflow when it enters the combustion chamber 260, which strengthens the contact and mixing with the air in the combustion chamber 260 and improves the combustion thermal efficiency. In this way, the mixture is discharged into the combustion chamber 260 at an angle, forming a rotating airflow in the combustion chamber 260, which effectively improves the mixing of fuel gas and air, thereby improving the utilization rate of fuel gas and the combustion thermal efficiency.

[0032] To further improve the mixing efficiency of air and fuel gas as they enter the outer mixing chamber and exit the ignition port, in this embodiment, a mixing mesh plate 400 is provided inside the outer mixing chamber. Naturally, the mixing mesh plate 400 has multiple mesh holes for ventilation. The mixing mesh plate 400 is fitted onto the outer side of the ignition base 200, and it covers multiple mixing grooves 110. After mixing in the outer mixing chamber, the fuel gas and air first pass through the mixing mesh holes. The partial obstruction of the ignition port by the mixing mesh plate 400 slows down the direct discharge of fuel gas and air from the ignition port. Under the pressure of the outer mixing chamber, the fuel gas and air pass through the mesh holes of the mixing mesh plate 400 and are released and discharged within the ignition port, thereby further improving the mixing efficiency of the fuel gas and air.

[0033] To improve the stability of the mixing mesh plate 400 during installation and positioning within the outer mixing chamber, in this embodiment, an annular step 240 is provided around the combustion groove 260 on the inner side of the outer mixing chamber, and an annular step 240 is also provided on the outer side of the ignition bottom. The upper cover 300 presses the mixing mesh plate 400 against the annular step 240. Thus, during installation, the annular step 240 provides support and positioning for the mixing mesh plate 400, effectively preventing it from detaching from the separator core, making the installation of the mixing mesh plate 400 more convenient and stable.

[0034] When the mixture of gas and air is discharged from the combustion chamber 260 and burned, air needs to be added to the combustion chamber 260 to improve combustion efficiency. Therefore, in this embodiment, an air intake column 250 is provided on the bottom side of the ignition base 200. An air intake channel 251 communicating with the combustion chamber 260 is formed in the air intake column 250. Multiple air intake columns 250 are arranged around the center of the ignition base 200. Connection holes are provided on the bottom side of the bottom shell 100 corresponding to the positions of the multiple air intake channels 251. In use, outside air can be added from below the ignition distributor to the multiple air intake channels 251, and from the multiple air intake channels 251 to the combustion chamber 260, thereby further supplementing the air required for combustion and improving the gas combustion efficiency.

[0035] The ignition base 200 and the bottom of the combustion chamber 260 need to be fixed at intervals. In order to facilitate the installation of the ignition base 200, in this embodiment, the bottom of the mixing chamber 110 is provided with protrusions 111 corresponding to the positions of the multiple air intake columns 250. Multiple connecting holes are formed in the middle of the multiple protrusions 111, and the bottoms of the multiple air intake columns 250 are respectively engaged with the multiple protrusions 111. The boss 111 strengthens the structural strength of the bottom of the mixing tank 110, thereby better securing the ignition base 200. When installing the ignition base 200, the bottom of the intake column 250 on its bottom side can be snapped onto the boss 111. For example, a protruding structure is provided at the bottom of the intake column 250, and holes that match the shape of the protruding structure are provided on the boss 111. By utilizing the cooperation between the protruding structure and the holes, the bottom of the intake column 250 can be snapped onto the boss 111, thus achieving quick and stable installation of the ignition base 200.

[0036] To improve the structural strength of the combustion chamber 260, in this embodiment, an arc-shaped protrusion 261 is formed in the middle of the bottom of the combustion chamber 260. The arc-shaped protrusion 261 itself can enhance the structural strength of the bottom of the combustion chamber 260, making the inner flame outlet less prone to deformation under high temperature conditions.

[0037] A type of gas stove, such as Figure 5 and Figure 6As shown, the furnace includes: the aforementioned burner; a furnace body 500, with a base 510 inside, the base 510 forming an upward-facing cavity, the bottom shell 100 connected to the center of the cavity; a windproof ring 600 connected to the bottom side of the base 510, the plane of the top side of the windproof ring 600 located below the plane of the top side of the base 510; a bracket 700 connected to the bottom side of the base 510, the bracket 700 having a rotatable support member 710, the top surface of the support member 710 serving as the support surface, the support surface being rotatable downwards to enter the windproof ring 600 or upwards to protrude from the windproof ring 600, and multiple brackets 700 surrounding the windproof ring 600.

[0038] In this gas stove, the burner can ignite and heat inside the cavity. The side wall of the base 510 itself forms an outer ring within the cavity that can block wind and concentrate energy. A windproof ring 600 is installed on the bottom side of the base 510 and forms an inner ring within the base 510 that can block wind and concentrate energy. In use, the boiler is placed on multiple supports 700, and the support members 710 on the supports 700 abut against the boiler for support. When the boiler is small, the multiple support members 710 rotate downwards to enter the fireproof ring, and the boiler is pressed down to abut against the multiple support members 710. At this time, the multiple support surfaces are inclined against the outside of the boiler to provide limiting support, and the support members 710 themselves can increase the direct support of the boiler. The inner ring formed by the fireproof ring can directly block wind and concentrate energy around the boiler, effectively improving the heating efficiency of the boiler. When the boiler is large, multiple support members 710 rotate upwards until their support surfaces protrude beyond the fireproof ring 600. The boiler presses down on the multiple support members 710, at which point the multiple support surfaces abut against the bottom side of the boiler to provide support. The outer ring formed by the side wall of the bottom support 510 can block wind and concentrate energy around the boiler. In this way, the rotation of multiple support members 710 can adapt to different boiler sizes, providing stable support for the boiler. Furthermore, the double-layer energy-concentrating structure of the inner and outer rings can provide a uniform heating environment for the boiler, which helps to reduce heat loss and improve heating efficiency.

[0039] There are several ways to rotatably connect the support member 710 to the bracket 700. For example, the support member 710 can be rotatably connected to the bracket 700 by hinge. In this embodiment, the top of the bracket 700 is provided with an arc-shaped convex corner on the side near the center of the base 510, and the bottom side of the support member 710 is provided with a connecting groove. The arc-shaped convex corner is rotatably connected to the connecting groove. When the support member 710 is rotated upward to protrude from the windproof ring 600, the bottom side of the support member 710 abuts against the top side of the bracket 700. The support member 710 is rotatably connected to the arc-shaped convex corner. One end of the support member 710 protrudes from the bracket 700, while the other end is located on the bracket 700. In use, when a small boiler is placed directly on the support member 710, the boiler can directly abut against the part of the support member 710 that protrudes from the bracket 700, causing the support member 710 to rotate downward. When a large boiler is placed on the support member 710, the bottom side of the boiler can abut against the part of the support member 710 located on the top side of the bracket 700. At this time, the support member 710 will not rotate, that is, it will remain in the state of rotating upward until the support surface protrudes from the windproof ring 600. At this time, the bottom side of the support member 710 abuts against the top side of the bracket 700, which can provide stable support for the support member 710, thereby ensuring the stability of the boiler placement.

[0040] The bracket 700 can be installed on the base 510 inside the windproof ring 600. In this embodiment, the bracket 700 is connected to the base 510 outside the windproof ring 600. The windproof ring 600 has a clearance hole for avoiding the support member 710. The bracket 700 is connected to the bottom side of the base 510. When installing the windproof ring 600, the clearance hole on the windproof ring 600 can be directly positioned with the bracket 700, and then the windproof ring 600 can be accurately connected to the base 510. At this time, the bracket 700 can limit the position of the windproof ring 600 and prevent the windproof ring 600 from rotating relative to the base 510. In use, the support member 710 can rotate downward at the clearance hole and enter into the windproof ring 600, making the overall structure more compact.

[0041] When a large boiler is placed on the support 710, the support surface is in contact with the bottom surface of the boiler. To improve the boiler's positioning effect, in this embodiment, the bracket 700 has an upwardly protruding positioning portion 720 on the side away from the center of the base 510. A concave angle can be formed between the positioning portion 720 and the support surface to position the boiler. When a flat-bottomed boiler is placed on the top side of multiple support 710s, the multiple positioning portions 720 can position the side walls of the boiler, further improving the stability of the boiler placement.

[0042] Furthermore, the limiting part 720 is provided with a limiting concave corner 721 near the center of the base 510. When a larger boiler needs to be placed, the boiler can be placed within the limiting concave corners 721 of the multiple limiting parts 720. At this time, the multiple limiting concave corners 721 are used directly to limit and support the boiler, further improving the overall versatility.

[0043] To improve the stability of the support surface in limiting the boiler when the support member 710 is tilted, in this embodiment, multiple locking teeth are provided on the top side of the support surface along its length. When placing a small boiler, the support member 710 rotates, and the locking teeth can lock onto the bottom surface of the boiler near the corners, thereby further improving the stability of the boiler placement.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
