Description

Technical Field

[0001] This invention relates to the field of kitchenware, and particularly to a flame spreader and a stove. Background Technology

[0002] Currently, the structure of burner on the market is relatively simple. A typical burner is a cylindrical structure with flame outlets evenly distributed on its circumferential surface. When cooking, if the liquid overflows, it drips onto the top of the burner and then flows down its circumference. If the overflow flows through the flame outlets, it can cause blockages.

[0003] Therefore, to solve this problem, an overflow port is usually provided at the top edge of the burner to guide the overflow from the top of the burner down the periphery of the burner from a specific location, preventing the overflow from flowing through other flame outlets. However, when a large amount of overflow drips onto the top of the burner, a single overflow port cannot effectively drain the overflow, causing other overflow points on the top of the burner to overflow. Adding more overflow ports to the top of the burner is not an effective solution to the problem of how to quickly drain large amounts of overflow, because flame outlets cannot be arranged below the added overflow ports. Increasing the number of overflow ports reduces the area available for flame outlets around the burner, thus affecting the heating efficiency of the burner. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect of poor overflow drainage effect of the existing flame distributor, and to provide a flame distributor and a stove.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution: a flame distributor includes a body, a flame outlet is provided on the periphery of the body, and an overflow port is provided on the top edge of the body. The periphery of the body includes a first periphery surface and a second periphery surface along the circumferential direction. The second periphery surface protrudes outward relative to the first periphery surface along the radial direction of the body. The flame outlet is respectively provided on the first periphery surface and the second periphery surface. On both sides of the second periphery surface along the circumferential direction, guide surfaces extending inward and connecting to the first periphery surface are respectively formed. The flame outlet is not provided on the guide surfaces. The number of overflow ports corresponds to the number of guide surfaces. The overflow ports are arranged above the corresponding guide surfaces.

[0006] In this design, by altering the peripheral layout of the flame distributor, its peripheral surface is divided into a first peripheral surface and a second peripheral surface. The second peripheral surface protrudes radially relative to the first peripheral surface, creating two additional guide surfaces between the second and first peripheral surfaces without reducing the lateral area of ​​the flame outlets. Overflow ports are positioned above these guide surfaces, increasing the number of overflow ports while preventing overflow from affecting the normal operation of the flame outlets. Simultaneously, the corner arrangements between the first and second peripheral surfaces, as well as between the guide surfaces and the second peripheral surface, effectively prevent overflow flowing through the guide surfaces from reaching either the first or second peripheral surface. Furthermore, by simultaneously arranging flame outlets on both the first and second peripheral surfaces, which have a radial drop, the flame outlets on the first and second peripheral surfaces have different flame ranges. This achieves uniform flame distribution and widespread heating, improving heating efficiency and reducing localized overheating and underheating of the cookware.

[0007] Preferably, the peripheral surface of the body includes a plurality of second peripheral surfaces along the circumferential direction, and the plurality of second peripheral surfaces are evenly distributed along the circumference.

[0008] In this design, by arranging multiple second circumferential surfaces on the peripheral surface of the main body, the number of overflow ports can be further increased, improving overflow drainage efficiency. Simultaneously, the increase in overflow ports does not affect the available area for the burner outlet, ensuring the heating capacity of the burner. Furthermore, the even distribution of multiple second circumferential surfaces along the circumference of the main body ensures that the center of gravity remains centrally located, effectively resolving the issue of center of gravity shift that occurs with a single protruding second circumferential surface. This effectively prevents improper assembly and potential gas leaks during reinstallation after user removal and cleaning due to the center of gravity shift.

[0009] Preferably, the number of the second peripheral side surfaces is three.

[0010] In this design, three second circumferential surfaces protruding relative to the first circumferential surface are evenly arranged on the peripheral surface of the main body. This allows for the arrangement of six overflow ports on the main body, improving overflow discharge efficiency. Simultaneously, the overflow from these six ports does not affect the flameout holes arranged on the first and second circumferential surfaces. Therefore, arranging three second circumferential surfaces on the peripheral surface of the main body significantly increases the overflow discharge rate compared to arranging two or fewer, while reducing the manufacturing difficulty of the flame distributor compared to arranging four or more.

[0011] Preferably, the flame outlet holes on the first circumferential surface and the flame outlet holes on the second circumferential surface are both oriented toward the central axis of the body.

[0012] In this design, all flame outlets face the central axis. Due to the difference in radial dimensions between the first and second circumferential side surfaces, the flame from the flame outlets is more diffused, resulting in a larger heated area for the cookware.

[0013] Preferably, the radial dimension of the body gradually increases from the top surface of the fire distributor to the bottom surface of the fire distributor.

[0014] In this design, by setting the top and bottom surfaces of the fire distributor, the radial dimension of the main body gradually increases, making the fire distributor more stable during use.

[0015] Preferably, the fire distributor includes a blocking part disposed on the upper end face of the main body, and the blocking part has a channel that communicates with the overflow port.

[0016] In this design, the structure is configured with a blocking part at the upper end of the main body and a channel that guides the overflow to the overflow port, preventing the overflow from flowing directly onto the first circumferential side surface. This effectively avoids liquid overflow interfering with the cooking process and protects the user's safety.

[0017] Preferably, a drainage groove is provided on the upper surface of the body, the drainage groove is connected to the channel, and the overflow port is formed at both ends of the drainage groove along the circumference of the body.

[0018] In this design, by creating a drainage channel, overflowing liquid flowing out of the channel can be guided into the drainage channel and discharged from the overflow outlets formed at both ends of the drainage channel along the circumference, thereby preventing the overflow from interfering with the cooking process. At the same time, the drainage channel also reduces the amount of overflow remaining on the upper surface of the main body, thus improving the ease of cleaning.

[0019] Preferably, the drainage channel includes a first channel wall and a second channel wall, the first channel wall and the second channel wall are distributed sequentially from the inside to the outside, and the second channel wall is higher than the first channel wall.

[0020] In this design, the structure prevents overflow when the liquid flows out of the drainage channel, reduces the risk of it flowing to the second circumferential side surface, and allows the liquid to flow out of the overflow port more smoothly, thus improving the overflow prevention effect.

[0021] Preferably, the blocking part has a storage space in the middle, and the side of the blocking part at the storage space is an inwardly inclined surface from top to bottom, and the storage space is connected to the channel.

[0022] In this design, the structure allows liquid to flow into the storage space and accumulate on the inclined surface of the blocking part, thus preventing overflow. Simultaneously, by connecting the storage space to the channel, the liquid can flow more smoothly into the channel and out through the overflow outlet, further enhancing the overflow prevention effect.

[0023] The present invention also discloses a stove, which includes the aforementioned burner, the burner including an ignition needle, the ignition needle corresponding to an ignition hole on the first peripheral surface;

[0024] Alternatively, the ignition distributor may include a thermocouple that corresponds to an ignition hole on the first peripheral surface.

[0025] In this design, the ignition holes on the first part correspond to the ignition needle and thermocouple of the stove. Compared to the second part, the ignition holes on the first part have a blocking effect, making them less likely to be blocked by soup or liquid, and easier to ignite. The stove has advantages such as a wider heating range, more uniform heating, and a lower probability of blocking the ignition holes. It can improve the service life and stability while ensuring the cooking effect, and enhance the user experience.

[0026] The positive and progressive effects of this invention are as follows: By changing the peripheral layout of the flame distributor, dividing its peripheral surface into a first peripheral surface and a second peripheral surface, and making the second peripheral surface bulge radially relative to the first peripheral surface, two additional guide surfaces are formed between the second and first peripheral surfaces without reducing the lateral area of ​​the flame outlet. By arranging overflow ports above these two guide surfaces, the number of overflow ports is increased while preventing overflow from affecting the normal operation of the flame outlet. Simultaneously, the corner layout between the first and second peripheral surfaces, as well as the corner layout between the guide surfaces and the second peripheral surface, effectively prevents overflow flowing through the guide surfaces from reaching either the first or second peripheral surface. Furthermore, by simultaneously arranging flame outlets on the first and second peripheral surfaces, which have a radial drop, the flame outlets on the first and second peripheral surfaces have different flame ranges, achieving uniform flame distribution and widespread heating, improving heating efficiency, and reducing localized overheating and underheating of the cookware.

[0049] Radial B Detailed Implementation

[0050] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0051] like Figures 1-5As shown, this embodiment discloses a stove, which includes a burner 1. The burner 1 includes a body 11. The body 11 has flame holes 110 on its periphery and an overflow port 111 on its top edge. The periphery of the body 11 includes a first periphery surface 112 and a second periphery surface 113 along the circumferential direction. The second periphery surface 113 protrudes outward relative to the first periphery surface 112 along the radial direction B of the body 11. The flame holes 110 are respectively provided on the first periphery surface 112 and the second periphery surface 113. On both sides of the second periphery surface 113 along the circumferential direction A, there are guide surfaces 114 that extend inward and connect to the first periphery surface 112. The guide surfaces 114 do not have flame holes 110. The number of overflow ports 111 corresponds to the number of guide surfaces 114. The overflow ports 111 are arranged above the corresponding guide surfaces 114.

[0052] In this design, by altering the peripheral layout of the flame distributor 1, the peripheral surface of the flame distributor 1 is divided into a first peripheral surface 112 and a second peripheral surface 113. The second peripheral surface 113 protrudes radially relative to the first peripheral surface 112, thereby creating two additional guide surfaces 114 between the second peripheral surface 113 and the first peripheral surface 112 without reducing the lateral area of ​​the flame outlet 110. By arranging overflow ports 111 above these two guide surfaces 114, the number of overflow ports 111 is increased while preventing overflow from the overflow ports 111 from affecting the normal operation of the flame outlet 110. Simultaneously, the corner layout between the first peripheral surface 112 and the guide surfaces 114, and the corner layout between the guide surfaces 114 and the second peripheral surface 113, effectively prevents overflow flowing through the guide surfaces 114 from flowing to the first peripheral surface 112 or the second peripheral surface 113. Furthermore, by simultaneously arranging flame outlets 110 on the first circumferential surface 112 and the second circumferential surface 113, which have a radial drop, the flame outlets 110 on the first circumferential surface 112 and the second circumferential surface 113 of the flame distributor 1 have different flame outlet ranges. This can achieve uniform flame distribution and widespread heating, improve heating efficiency, and reduce local overheating and undercooling of the cookware.

[0053] In this embodiment, the peripheral surface of the body 11 includes a plurality of second peripheral surfaces 113 along the circumferential direction, and the plurality of second peripheral surfaces 113 are evenly distributed along the circumference. Of course, in other alternative embodiments, the distribution of the second peripheral surfaces 113 along the circumference may also be non-uniform.

[0054] In this embodiment, by arranging multiple second circumferential surfaces 113 on the peripheral surface of the main body 11, the number of overflow ports 111 can be further increased, improving the overflow efficiency. Simultaneously, the increase in overflow ports 111 does not affect the available area for the flame outlet, ensuring the heating capacity of the flame distributor 1. Furthermore, by evenly distributing multiple second circumferential surfaces 113 along the circumference of the main body 11, the center of gravity of the main body 11 remains centrally located. This effectively solves the problem of center of gravity shift in the main body 11 caused by a single protruding second circumferential surface 113, thus effectively preventing improper assembly and gas leakage during reinstallation of the main body 11 after removal and cleaning due to the center of gravity shift.

[0055] like Figure 1 and Figure 2 As shown, there are three second peripheral surfaces 113. Specifically, there are three first peripheral surfaces 112 and three second peripheral surfaces 113. The first peripheral surfaces 112 and the second peripheral surfaces 113 are alternately distributed, and the three second peripheral surfaces 113 divide the peripheral surface of the body 11 into three equal parts. Of course, in other alternative embodiments, one first peripheral surface 112 and one second peripheral surface 113 can also be provided. The three second peripheral surfaces 113 protruding relative to the first peripheral surface 112 are evenly arranged on the peripheral surface of the body 11, so that six overflow ports 111 can be arranged on the body 11, improving the overflow discharge efficiency. At the same time, the overflow from the six overflow ports 111 will not affect the flame outlets 110 arranged on the first peripheral surfaces 112 and the second peripheral surfaces 113. Therefore, arranging three second peripheral surfaces 113 on the peripheral surface of the body 11 can significantly improve the overflow discharge speed compared to arranging two or fewer second peripheral surfaces 113, and can reduce the processing difficulty of the fire distributor 1 compared to arranging four or more second peripheral surfaces 113.

[0056] Specifically, the flame outlets 110 on the first circumferential side surface 112 and the second circumferential side surface 113 are both oriented towards the central axis of the body 11. Since the first circumferential side surface 112 and the second circumferential side surface 113 have different radial dimensions, the flames from the flame outlets 110 are more diffused, resulting in a larger heated area for the cookware. Of course, in other alternative embodiments, the flame outlets 110 on the first circumferential side surface 112 and the second circumferential side surface 113 can also be configured with other orientations.

[0057] like Figure 1 and Figure 2 As shown, the radial dimension of the body 11 gradually increases from the top surface to the bottom surface of the fire distributor 1. By setting the radial dimension of the body 11 to gradually increase from the top surface to the bottom surface of the fire distributor 1, the fire distributor 1 becomes more stable during use.

[0058] like Figure 1 As shown, the cooker 1 includes a blocking part 12, which is disposed on the upper end face 115 of the main body 11. A channel 121 is formed on the blocking part 12, communicating with the overflow port 111. By providing the blocking part 12 and the channel 121 at the upper end of the main body 11, the channel 121 guides the overflow towards the overflow port 111, preventing the overflow from flowing directly onto the first peripheral surface 112. This effectively avoids liquid overflow interfering with the cooking process and protects user safety. Of course, in other alternative embodiments, the blocking part 12 and the channel 121 may not be provided.

[0059] like Figure 1 As shown, a drainage groove 116 is provided on the upper end face 115 of the main body 11. The drainage groove 116 is connected to the channel 121, and overflow ports 111 are formed at both ends of the drainage groove 116 along the circumference of the main body 11. By providing the drainage groove 116, the overflow liquid flowing out of the channel 121 can be guided into the drainage groove 116 and flow out from the overflow ports 111 formed at both ends of the drainage groove 116 along the circumference, thereby avoiding the overflow liquid from interfering with the cooking process. At the same time, the provision of the drainage groove 116 can also reduce the retention of overflow liquid on the upper end face 115 of the main body 11, thereby improving the ease of cleaning. Of course, in other alternative embodiments, the drainage groove 116 may not be provided, and the overflow liquid flows out from the overflow port 111 when it flows out from the channel 121 to the overflow port 111.

[0060] like Figure 1 and Figure 3 As shown, the drainage channel 116 includes a first channel wall 1161 and a second channel wall 1162, which are distributed sequentially from the inside to the outside. The second channel wall 1162 is higher than the first channel wall 1161. This design prevents overflow when liquid flows out of the drainage channel 116, reduces the risk of liquid flowing to the second peripheral surface 113, and allows the liquid to flow out more smoothly from the overflow port 111, thus improving the anti-overflow effect. Of course, in other alternative embodiments, the heights of the first channel wall 1161 and the second channel wall 1162 can also be the same, that is, a baffle can be set above the second peripheral surface 113 to prevent liquid from flowing to the second peripheral surface 113.

[0061] like Figure 1As shown, a storage space 122 is provided in the middle of the blocking part 12. The side of the blocking part 12 at the storage space 122 is an inwardly sloping surface from top to bottom. The storage space 122 is connected to the channel 121. This allows liquid to flow into the storage space 122 and collect on the sloping surface of the blocking part 12, thereby preventing overflow. At the same time, by connecting the storage space 122 to the channel 121, liquid can flow more smoothly into the channel 121 and out from the overflow port 111, thereby further improving the overflow prevention effect.

[0062] like Figure 5 As shown, the burner 1 also includes an ignition needle 2, which corresponds to the ignition hole on the first peripheral surface 112; the burner 1 also includes a thermocouple, which corresponds to the ignition hole on the first peripheral surface 112. The ignition hole on the first peripheral surface 112 corresponds to the ignition needle 2 and the thermocouple of the stove. Compared with setting the ignition hole at the second peripheral surface 113, the flame outlet hole 110 on the first peripheral surface 112 has the blocking effect of the blocking part 12, which is less likely to be blocked by soup liquid and facilitates ignition; the stove has the advantages of a wider heating range, more uniform heating, and a lower probability of blocking the flame outlet hole 110, which can improve the service life and stability while ensuring the cooking effect and enhancing the user experience.
