All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0038] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components.

[0039] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0040] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0041] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.
[0042] In existing technology, top-intake burners are placed directly on the gas stove panel, with a gap between the bottom of the burner body and the panel. During combustion, air is introduced through this gap. However, the heat generated by the burner during combustion can radiate directly downwards to the gas stove panel, causing the panel temperature to rise and posing safety risks such as burns or panel cracking.
[0043] After repeated consideration and verification, the inventors discovered that integrating the pot rack and burner together, with a partition at the bottom of the pot rack, and the pot rack having a downward-opening heat storage chamber surrounding the burner, would effectively prevent heat from the burner from radiating to the gas stove panel. This reduces the panel's temperature rise and prevents burns or panel cracking. The burner's air intake is positioned to pass through the partition, ensuring a single intake for successful combustion.
[0044] In view of this, the inventor designed a combustion device and a gas stove. The combustion device integrates the burner with a pot rack, and a downward-opening heat storage chamber is set on the pot rack. A baffle is installed at the bottom of the pot rack to seal the opening of the heat storage chamber. The baffle prevents the heat generated by the burner from radiating to the gas stove panel, thereby reducing the temperature rise of the panel and preventing burns or panel cracking. A hole is set in the middle of the baffle, and an air inlet is set at the bottom of the burner, passing through the hole to ensure primary air intake of the burner.
[0045] The technical solutions of the combustion device and gas stove provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0046] Reference Figures 1 to 9 As shown, the combustion device provided in this application embodiment includes a burner 100, a pot frame 200, and a partition 300. The pot frame 200 surrounds the outside of the burner 100 and is fixed to the burner 100, and the outer periphery of the burner 100 is in close contact with the pot frame 200.
[0047] The burner 100 is a top-inlet burner. Schematic, the burner 100 includes a base and a flame cap mounted on the base, while the pot support 200 includes a support and feet mounted on the support. The support surrounds and is fixed to the base. In one possible implementation, the base of the burner 100 and the pot support 200 can be integrally molded. In another possible implementation, the base of the burner 100 and the pot support 200 can be locked and fixed using threads or fasteners. The combustion device has a relatively simple structure. Fixing the burner 100 and the pot support 200 together forms a single integrated structure, facilitating installation and maintenance, improving user experience, reducing placement issues, and minimizing the space occupied by the combustion device.
[0048] The pot frame 200 has a downward-opening heat storage chamber 210, which surrounds the burner 100. The heat storage chamber 210 can be integrally formed onto the support of the pot frame 200. Figure 3 and Figure 5 As shown, the heat storage cavity 210 extends from the burner 100 to the outer edge of the pot rack 200.
[0049] A partition 300 is installed at the bottom of the pot rack 200 to seal the opening of the heat storage chamber 210. A hole 310 is provided in the middle of the partition 300. For example, the partition 300 can be made of metal, and its outer edge shape can match the outer edge shape of the pot rack 200. The partition 300, pot rack 200, and burner 100 form an integral structure. For example, the partition 300 can be fixed to the pot rack 200 by welding or fasteners. The air in the heat storage chamber 210 prevents heat from the pot rack 200 from being directly transferred to the partition 300, thus providing good heat insulation at the bottom of the pot rack 200. When the combustion device is placed on the gas stove panel 20, the main body of the burner 100 and the main body of the pot rack 200 are both located above the partition 300, i.e., on the side of the partition 300 facing away from the panel 20. The baffle 300 can effectively prevent the heat generated by the burner 100 during combustion from radiating downwards to the panel 20.
[0050] The burner 100 has an air inlet 110 at its bottom end, which extends through a hole 310. For example, the air inlet 110 can be a cylindrical structure, with an ejector tube for the burner 100 located inside. Primary air is supplied to the burner 100 through the air inlet 110. The cross-sectional shape of the hole 310 on the baffle 300 can match the cross-sectional shape of the air inlet 110, ensuring that the baffle 300 does not obstruct the primary air intake of the burner 100 and guaranteeing smooth combustion.
[0051] The combustion device provided in this embodiment, by installing a baffle 300 at the bottom of the pot rack 200, ensures that the air in the heat storage chamber 210 prevents the heat from the pot rack 200 from being directly transferred to the baffle 300. The baffle 300 has a heat insulation function, which can effectively prevent the heat generated by the burner 100 from radiating to the gas stove panel 20, thereby reducing the temperature rise of the panel 20 and preventing burns or cracking of the panel 20. Furthermore, the baffle 300 does not obstruct the primary air intake of the burner 100, ensuring smooth combustion of the burner 100.
[0052] Furthermore, during combustion, the air in the heat storage chamber 210 absorbs heat. As combustion continues, the air in the heat storage chamber 210 becomes thermally saturated, at which point it stops absorbing heat, reducing heat loss during combustion. When the burner 100 is operating, the radiant heat from the flame reaches the surface of the pot frame 200 and is conducted into the heat storage chamber 210. The conductive heat from the burner 100 itself further increases the temperature of the air in the heat storage chamber 210, allowing it to reach thermal saturation more quickly and further reducing heat loss. These features improve the thermal energy utilization rate and thermal efficiency of the combustion device.
[0053] In one embodiment, such as Figure 2 , Figure 5 and Figure 6 As shown, there is an expansion gap 400 between the partition 300 and the pot frame 200 and / or the air inlet 110, and the expansion gap 400 connects the heat storage chamber 210 with the outside.
[0054] Understandably, the baffle 300 does not completely block the opening of the heat storage chamber 210, and the air in the heat storage chamber 210 and the outside air can be connected through the expansion gap 400. The baffle 300 may have an expansion gap 400 only with the pot support 200 or only with the air inlet 110, or the baffle 300 may have expansion gaps 400 with both the pot support 200 and the air inlet 110. Those skilled in the art will understand that when the burner 100 is burning, the air in the heat storage chamber 210 may absorb heat and undergo thermal expansion. Some of the expanded air can be discharged through the expansion gap 400. That is, the expansion gap 400 provides a certain amount of space for the air in the heat storage chamber 210 to be discharged, and the combustion device will not be deformed or damaged due to the expansion of superheated gas in the heat storage chamber 210.
[0055] When the combustion device is placed on the gas stove panel 20, a supply channel is formed between the main body of the pot holder 200 and the panel 20 in the circumferential direction of the combustion device. Primary air can flow along... Figure 8 and Figure 9 The air enters the injector in the intake section 110 through the supply channel and mixes with the combustion gas. When the primary air enters the burner 100, the temperature of the incoming air is relatively low, which can cool the panel 20 and reduce the risk of local overheating and cracking of the panel 20.
[0056] When the air in the heat storage chamber 210 reaches a certain temperature, it will expand thermally. Some of the air in the heat storage chamber 210 will be discharged from the heat storage chamber 210 through the expansion gap 400. The air discharged from the heat storage chamber 210 can heat the primary air, realizing the recovery and utilization of heat.
[0057] By setting the expansion gap 400, the air in the heat storage chamber 210 can be smoothly discharged after expansion, ensuring that the panel 20 below the combustion device does not overheat while guaranteeing the reliability of the combustion device. The air discharged from the expansion gap 400 can heat the primary air, thereby improving the combustion efficiency and flame stability of the combustion device.
[0058] In other embodiments, through holes can be made in the partition 300 as expansion gaps 400, and the air in the heat storage cavity 210 can be discharged from the heat storage cavity 210 through the through holes in the partition 300 after it expands due to heat.
[0059] In a specific embodiment, such as Figure 2 , Figure 5 and Figure 6 As shown, the expansion gap 400 is located between the air intake 110 and the hole 310, and the expansion gap 400 is arranged around the air intake 110.
[0060] Specifically, the cross-sectional dimension of the hole 310 is larger than that of the air inlet 110. After the partition 300 is assembled with the pot holder 200, an expansion gap 400 is formed between the side wall of the air inlet 110 and the hole 310, surrounding the air inlet 110. Those skilled in the art can set the specific width of the expansion gap 400 as needed, and no unique limitation is made here.
[0061] Those skilled in the art will understand that during the combustion process, the air inlet 110 at the bottom of the burner 100 has a high temperature. By providing an expansion gap 400 between the hole 310 of the baffle 300 and the air inlet 110, excessive heat from the air inlet 110 can be prevented from being transferred to the baffle 300, thereby preventing the baffle 300 from having a high local temperature and improving the reliability of the baffle 300.
[0062] like Figures 3-5 As shown, the outer edge of the pot rack 200 is provided with a downwardly extending first flange 220, and the outer edge of the partition 300 abuts against the first flange 220.
[0063] Specifically, during use, the first flange 220 extends towards the panel 20 of the gas stove. The first flange 220 surrounds the outer edge of the pot rack 200. For example, the first flange 220 can be integrally formed onto the outer edge of the pot rack 200. The partition 300 is located within the area enclosed by the first flange 220, and its outer edge abuts against the first flange 220.
[0064] The cooperation between the first flange 220 and the partition 300 can restrict the lateral movement of the partition 300 relative to the pot frame 200. During the assembly process, the partition 300 and the pot frame 200 can play a pre-fixing role, making it convenient for workers to fix the partition 300 to the bottom of the pot frame 200.
[0065] Figures 3-5 As shown, the outer edge of the partition 300 is provided with a second flange 320, the extension direction of the second flange 320 is parallel to the extension direction of the first flange 220, and the second flange 320 is close to the first flange 220.
[0066] The second flange 320 can extend upwards or downwards. The second flange 320 is arranged around the outer edge of the partition 300. Optionally, the second flange 320 can be formed on the outer edge of the partition 300 by stretching. After the partition 300 and the pot holder 200 are assembled, the side of the second flange 320 facing away from the air intake 110 is tightly fitted against the side of the first flange 220 facing the air intake 110.
[0067] This structure, through the cooperation between the second flange 320 and the first flange 220, increases the contact area between the outer edge of the partition 300 and the pot frame 200, thereby increasing the sealing between the outer edge of the partition 300 and the pot frame 200. The air in the heat storage cavity 210 can effectively reduce the heat loss of the burner 100 during combustion.
[0068] In one embodiment, such as Figure 2 and Figure 3 As shown, the burner 100 is also provided with a mounting part 120 at the bottom end, and the bottom end of the air inlet 110 extends beyond the mounting part 120. The mounting part 120 abuts against the partition 300 and is fixed to the partition 300.
[0069] In this design, the bottom surface of the mounting portion 120 serves as the abutment surface, and after assembly, the top surface of the partition 300 abuts against the abutment surface. In one possible implementation, fasteners can be used to pass through the partition 300 and lock it onto the mounting portion 120, thereby fixing the partition 300 to the bottom of the pot frame 200.
[0070] Understandably, by limiting the height of the bottom of the mounting part 120, the installation height of the partition 300 can be limited, thereby limiting the height of the heat storage chamber 210. This ensures the heat insulation function of the partition 300 while reducing heat loss from the burner 100 during combustion. In addition, the mounting part 120 is designed to abut against the partition 300, making it easier to fix the partition 300 to the bottom of the boiler frame 200.
[0071] In a specific embodiment, such as Figure 2 , Figure 3 and Figure 5 As shown, the partition 300 protrudes downward from the middle to form a protrusion 330, and the inner wall of the protrusion 330 defines a receiving cavity. For example, the cross-sectional shape of the protrusion 330 is circular, and the protrusion 330 can be formed in the middle of the partition 300 by stamping.
[0072] The bottom end of the mounting portion 120 extends into the receiving cavity and abuts against the bottom wall of the receiving cavity. A hole 310 is provided on the protrusion 330. The end of the protrusion 330 facing the panel 20 is formed as a flat surface, allowing the bottom wall of the receiving cavity to be parallel to the panel 20. The vertical projection of the mounting portion 120 lies within the receiving cavity defined by the protrusion 330. After the partition 300 and the pot holder 200 are assembled, the bottom end of the mounting portion 120 abuts against the bottom wall of the receiving cavity.
[0073] By providing a protrusion 330 in the middle of the partition 300, the distance between the portion of the partition 300 located outside the protrusion 330 and the panel 20 is increased, thereby appropriately reducing the volume of the heat storage chamber 210. During combustion, the air in the heat storage chamber 210 can be thermally saturated more quickly, thus reducing heat loss from the burner 100 during combustion more rapidly.
[0074] In one embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, the top surface of the pot holder 200 includes a first connecting surface 230, a second connecting surface 240, and a third connecting surface 250. The first connecting surface 230 surrounds the outside of the burner 100, the second connecting surface 240 surrounds the outside of the first connecting surface 230, and the third connecting surface 250 surrounds the outside of the second connecting surface 240. The height of the second connecting surface 240 gradually decreases in the direction away from the burner 100.
[0075] The inner edge of the first connecting surface 230 can connect with the base of the burner 100, the inner edge of the second connecting surface 240 can connect with the outer edge of the first connecting surface 230, and the inner edge of the third connecting surface 250 can connect with the outer edge of the second connecting surface 240. Schematic, the second connecting surface 240 forms an approximately "conical" structure, and its height gradually decreases from the inside to the outside. The first connecting surface 230 is located at the top of the support, the second connecting surface 240 is located in the middle of the support, the third connecting surface 250 is located at the bottom of the support, and the burner cap of the burner 100 is located above the first connecting surface 230.
[0076] When the combustion device is in combustion, the heat from the combustion can be transferred to the first connecting surface 230, the second connecting surface 240, and the third connecting surface 250, causing the temperature of the three connecting surfaces to rise. During combustion, secondary air flows through the first connecting surface 230, the second connecting surface 240, and the third connecting surface 250 to the flame position.
[0077] With the above configuration, the third connecting surface 250, the second connecting surface 240, and the first connecting surface 230 can guide secondary air to the flame of the combustion device, facilitating secondary air intake for the combustion device. Furthermore, the third connecting surface 250, the second connecting surface 240, and the first connecting surface 230 can heat the secondary air; the heated secondary air supplied to the flame of the combustion device helps improve the combustion efficiency and flame stability of the combustion device.
[0078] In one specific embodiment, the bottom of the pot holder 200 is provided with a support leg 260, the projection of the support leg 260 in the vertical direction is located within the third connecting surface 250, and the support leg 260 is disposed through the partition 300.
[0079] For example, there can be four legs 260, located at the four corners of the pot rack 200. The combustion device can be placed on the gas stove panel 20 via the legs 260, creating a gap between the main body of the pot rack 200 and the panel 20. Figure 8 and Figure 9 As shown, the primary air required for combustion of the combustion device can flow to the burner 100 through the gap in the direction indicated by the arrow.
[0080] When the combustion device is burning, the first connecting surface 230 is closest to the combustion flame and has a higher thermal radiation temperature. Since the first connecting surface 230 is integrally connected to the burner 100, it also receives heat conducted from the burner 100, resulting in the highest temperature on the first connecting surface 230. The second connecting surface 240 is located between the first connecting surface 230 and the third connecting surface 250. The second connecting surface 240 absorbs the radiant heat of combustion and the high-temperature conduction from the first connecting surface 230, resulting in a lower temperature than the first connecting surface 230. The third connecting surface 250 is connected to the lowest point of the second connecting surface 240 and is furthest from the flame, thus having the lowest radiant temperature. The temperature of the third connecting surface 250 is also lower than that of the second connecting surface 240. The support leg 260 is located below the third connecting surface 250. During combustion, the conduction temperature of the support leg 260 is lower, reducing the risk of excessively high local temperatures on the gas stove panel 20, which could lead to the panel 20 cracking.
[0081] like Figure 3 As shown, a notch 340 can be provided on the partition 300 for the support leg 260 to pass through. Since the support leg 260 passes through the partition 300, the support leg 260 can position the partition 300 during assembly with the pot rack 200, which facilitates the fixing of the partition 300 and the pot rack 200.
[0082] This application also provides a gas stove, including a panel 20 and the aforementioned combustion device, the combustion device being placed on the panel 20.
[0083] The gas stove provided in this application uses the aforementioned combustion device, resulting in a lower temperature rise of the panel 20 during use, which can prevent burns or cracking of the panel 20, thus ensuring a high level of safety for the gas stove.
[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
