DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0040] Please also refer to Figures 1 to 2 The embodiment of the present application provides a stove 1, which includes a burner 11 and a pot stand 12. The burner 11 includes an inner combustion portion 111, an outer combustion portion 112 surrounding the outer side of the inner combustion portion 111, and a liquid receiving pan 113. An air passage 114 is formed between the inner combustion portion 111 and the outer combustion portion 112; the pot stand 12 is arranged in an annular shape to have a central through hole 121 and is provided with a first air inlet passage 122. The pot stand 12 is located above the liquid receiving pan 113; the air outlet of the first air inlet passage 122 is located above the outer combustion portion 112; the lower surface of the pot stand 12 is spaced apart from the liquid receiving pan 113 in the vertical direction to form a second air inlet passage 13, and the second air inlet passage 13 is connected to the air passage 114; the fire hole 118 of the inner combustion portion 111 and the fire hole 118 of the outer combustion portion 112 are both located in the central through hole 121.

[0041] It should be noted that a gas passage 115 is formed inside the burner 11, and flame holes 118 are provided in both the outer combustion section 112 and the inner combustion section 111, communicating with the gas passage 115. Specifically, a mixture of gas and primary air is ejected from the flame holes 118 of the burner 11 and ignited by an ignition device, forming a flame with the aid of secondary air. This flame can be used to heat the cookware.

[0042] In some structural forms, the burner 11 may include a gas distribution plate (not shown), an inner ring fire cover 116, and an outer ring fire cover 117. The gas distribution plate and the inner ring fire cover 116 are connected to form the inner combustion section 111, and the gas distribution plate and the outer ring fire cover 117 are connected to form the outer combustion section 112. The gas distribution plate can be an integrated structure or a split structure, which is not limited in this application.

[0043] Depending on actual needs, pot rack 12 can be square, circular, or other shapes, and is not specifically limited here. Pot rack 12 is annular and has a central through hole 121. Central through hole 121 can be circular, square, or other shapes, and is not specifically limited here. Furthermore, pot rack 12 can be made of cast iron, enameled, or galvanized materials that have advantages such as high temperature resistance, excellent strength, and good thermal conductivity.

[0044] The cross-section of the first air inlet channel 122 can be of various shapes. The cross-section of the first air inlet channel 122 can be circular, square, or any other shape, and these are not specifically defined herein. The first air inlet channel 122 extends at least radially along the main body of the pot support 12. The first air inlet channel 122 can extend in a wavy shape, or in a straight line, and these are not specifically defined herein. The cross-section of the second air inlet channel 13 can be of various shapes. The cross-section of the second air inlet channel 13 can be circular, square, or any other shape, and these are not specifically defined herein. The second air inlet channel 13 extends at least radially along the main body of the pot support 12. The second air inlet channel 13 can extend in a wavy shape, or in a straight line, and these are not specifically defined herein.

[0045] The pot rack 12 can be placed on the liquid receiving pan 113 by abutting, or can be installed on the liquid receiving pan 113 by buckling, plugging, etc., which is not specifically limited here.

[0046] It should be noted that a first air inlet channel 122 is provided in the pot rack 12. After the secondary air enters the first air inlet channel 122, it contacts the inner wall surface of the first air inlet channel 122, thereby performing heat exchange to preheat the secondary air. After the secondary air enters the second air inlet channel 13 formed between the pot rack 12 and the liquid receiving pan 113, it contacts the lower surface of the pot rack 12, thereby performing heat exchange to preheat the secondary air.

[0047] When the burner 11 heats the cookware, an air pressure difference is generated between the inner side and the outer side of the pot rack 12 , and external air enters from the first air inlet channel 122 and the second air inlet channel 13 respectively, thereby forming secondary air to supplement the fire hole 118 of the burner 11 .

[0048] In the prior art, the pot stand 100 is typically provided with an air intake duct 111 to preheat secondary air, thereby mixing the preheated secondary air with the mixed gas ejected from the flame holes 250 to improve combustion efficiency. However, the pot stand 100 in the prior art only directs the preheated secondary air into the air passage 114 via the air intake duct 111, and fails to accurately direct the secondary air to the inner combustion section 111 and the outer combustion section 112. As a result, the outer combustion section 220 does not receive sufficient secondary air.

[0049] In the embodiment of the present application, the first air inlet passage 122 precisely guides the secondary air to the outer combustion section 112, and the second air inlet passage 13 precisely guides the secondary air to the air passage 114, thereby ensuring that the secondary air fully contacts the inner combustion section 111 and the outer combustion section 112. When the stove 1 is in use, the burner 11 heats the pot rack 12, allowing the first air inlet passage 122 and the second air inlet passage 13 to preheat the secondary air. The preheated secondary air mixes with the mixed gas ejected from the fire hole 118 of the burner 11, improving combustion efficiency and forming a flame with a higher ignition temperature, thereby efficiently and effectively heating the pot, improving heating efficiency, and thus improving the thermal efficiency of the stove 1. At the same time, the second air inlet passage 13 is formed by the pot rack 12 and the liquid receiving pan 113, eliminating the need to provide a channel within the pot rack 12 to guide the secondary air into the air passage 114, thereby simplifying the structure of the pot rack 12.

[0050] See also Figure 2 In some embodiments of the present application, the first air inlet channel 122 includes a first section 1221 and a second section 1222 in sequence along the air inlet direction, and the cross-sectional area of ​​the second section 1222 is smaller than that of the first section 1221. It is understood that the air inlet direction refers to the flow direction of the secondary air, and the secondary air first passes through the second section 1222 of the first air inlet channel 122 before entering the first section 1221. With this configuration, the cross-sectional area of ​​the second section 1222 is smaller than that of the first section 1221, so that the secondary air is compressed when entering the second section 1222, thereby allowing the secondary air to fully contact the inner wall of the first air inlet channel 122 when passing through the second section 1222, thereby improving the preheating effect of the pot rack 12 on the secondary air.

[0051] The first section 1221 and the second section 1222 can extend in various directions. For example, the first section 1221 and the second section 1222 can both extend radially of the pot support 12. Alternatively, the second section 1222 can extend radially of the pot support 12, while the first section 1221 can extend axially of the pot support 12, such that the second section 1222 and the first section 1221 are arranged at an angle in their extension directions. A variety of these directions are omitted here. The cross-sectional shapes of the first section 1221 and the second section 1222 can be different, as long as the cross-sectional area of ​​the first section 1221 matches the cross-sectional area of ​​the second section 1222. Preferably, the first section 1221 and the second section 1222 are connected by an oblique guide surface, thereby improving the fluidity of the secondary air within the first air intake passage 122.

[0052] Optionally, please also refer to Figures 2 to 3 The first air inlet channel 122 is arranged in an annular shape. Such an arrangement increases the space of the first air inlet channel 122, thereby increasing the contact area between the secondary air and the inner wall of the first air inlet channel 122, thereby improving the preheating effect of the pot rack 12 on the secondary air.

[0053] Optionally, please also refer to Figures 2 to 3 The second air inlet channel 13 is arranged in an annular shape. Such an arrangement increases the space of the second air inlet channel 13, thereby increasing the contact area between the secondary air and the lower surface of the pot rack 12, thereby improving the preheating effect of the pot rack 12 on the secondary air.

[0054] Furthermore, a plurality of grooves are provided on the lower surface of the pot rack 12, and the plurality of grooves are arranged along the circumference of the pot rack 12. The grooves are provided through the two groove walls in the radial direction of the pot rack 12. In this manner, the area of ​​the lower surface of the pot rack 12 can be increased by the grooves, thereby increasing the contact area between the secondary air and the lower surface of the pot rack 12 after entering the second channel, thereby improving the preheating effect of the pot rack 12 on the secondary air.

[0055] Please also refer to Figures 2 to 3 In some embodiments of the present application, the pot stand 12 includes a lower cover 123 and an upper cover 124. The lower cover 123 is arranged in an annular shape and is located above the liquid receiving pan 113. The lower cover 123 and the liquid receiving pan 113 form a second air inlet channel 13. The upper cover 124 is arranged in an annular shape and is located above the lower cover 123. The upper cover 124 and the lower cover 123 form a first air inlet channel 122. It should be noted that the inner side of the upper cover 124 and the inner side of the lower cover 123 form a central through hole 121. With this arrangement, the lower cover 123 and the upper cover 124 form the first air inlet channel 122, making it easy for users to separate the upper cover 124 and the lower cover 123 to maintain the first air inlet channel 122.

[0056] The lower cover 123 can extend in the radial direction of the pot support 12. At this time, since the air outlet of the first air inlet channel 122 is located above the outer combustion part 112, the lower cover 123 is located above the outer combustion part 112 as a whole. The lower cover 123 can also partially extend in the direction close to the liquid receiving pan 113. Since the air outlet of the first air inlet channel 122 is located above the outer combustion part 112, the inner side of the lower cover 123 can be located above the outer combustion part 112. Preferably, the lower cover 123 partially extends in the direction close to the liquid receiving pan 113. This can reduce the minimum vertical distance between the lower cover 123 and the liquid receiving pan 113, so that the secondary air can fully contact the lower surface of the lower cover 123 after entering the second air inlet channel 13, thereby improving the preheating effect of the pot support 12 on the secondary air.

[0057] Further, please also refer to Figures 3 and 4 The lower cover 123 includes a first main body portion 1231 and a first guide portion 1232 that are connected to each other. The first main body portion 1231 extends radially of the pot rack 12. The first guide portion 1232 is located on the outside of the first main body portion 1231 and extends toward the direction close to the liquid receiving pan 113. The upper cover 124 includes a second main body portion 1241 and a second guide portion 1242 that are connected to each other. The second main body portion 1241 extends radially of the pot rack 12. The second guide portion 1242 is located on the outside of the second main body portion 1241 and extends toward the direction close to the liquid receiving pan 113. The first guide portion 1232 is located on the inside of the second guide portion 1242. The distance between the first guide portion 1232 and the pot rack 12 is smaller than the distance between the second guide portion 1242 and the pot rack 12. It can be understood that the second main body portion 1241 and the second guide portion 1242 are surrounded by the upper cover 124 to form a receiving groove 1244, the lower cover 123 is partially located in the receiving groove 1244, the first guide portion 1232 partially extends out of the notch of the receiving groove 1244, and the first guide portion 1232 and the second guide portion 1242 are surrounded to form a guide channel 127, and the guide channel 127 is connected to the first air intake channel 122.

[0058] With this arrangement, the external air will be affected by the pressure difference and enter the pot rack 12, and part of the external air will be guided by the part of the first guide part 1232 extending out of the accommodating groove 1244, thereby entering the guide channel 127, thereby increasing the secondary air entering the first air inlet channel 122.

[0059] For details, please refer to Figures 2 to 3The pot rack 12 also includes pot legs 125, which connect the lower cover 123 and the upper cover 124 and support the pot. This arrangement simplifies the structure of the pot rack 12 by connecting the connecting member to the pot rack 12 via the pot legs 125. The pot legs 125 can be connected to the pot rack 12 through one or more methods, such as welding, screwing, or clamping. This means that the heat exchange assembly is mounted to the pot rack 12 via the pot bracket.

[0060] It should be noted that the pot legs 125 are located at the top of the pot stand 12 body, providing support for the bottom of the pot. Optionally, the pot legs 125 can be elongated to increase the connection area between the pot legs 125 and the bottom of the pot. This enhances the stability of the pot support, prevents the pot from sliding or tipping over during heating, reduces the risk of accidental injuries, and ensures a stable cooking process. Furthermore, the pot legs 125 can be made of a high-temperature-resistant material such as cast iron, though this is not a limitation in this embodiment. There can be multiple pot legs 125, each connected to the top of the pot stand 12 body along the circumference of the pot stand 12 body. This enhances the pot support along the circumference of the pot stand 12 body. The pot stand 12 body is placed on the liquid pan 113 of the burner 11 via the pot legs 125.

[0061] Optionally, please also refer to Figures 3 and 4 The pot support leg 125 is provided with a first mounting portion 1251, and the upper cover 124 is screwed to the first mounting portion 1251. In this way, the upper cover 124 and the pot support leg 125 are detachably connected, thereby facilitating maintenance of the upper cover 124 and the pot support leg 125.

[0062] Optionally, see Figure 3 The pot support leg 125 is provided with a second mounting portion 1252 that extends into the air intake passage, and the lower cover 123 is screwed to the second mounting portion 1252. This arrangement allows the lower cover 123 and pot support leg 125 to be detachably connected, thereby facilitating maintenance of the lower cover 123 and pot support leg 125. Furthermore, the second mounting portion 1252 extends into the first air intake passage 122. After the secondary air enters the first air intake passage 122, it will also come into contact with the portion of the second mounting portion 1252 that extends into the first air intake passage 122 for heat exchange, thereby enhancing the pot rack 12's preheating effect on the secondary air.

[0063] Please also refer to Figures 2 to 3In some embodiments of the present application, the upper cover 124 is provided with a first mounting hole 1243 in the vertical direction, and the lower cover 123 is provided with a second mounting hole 1233 in the vertical direction; the pot legs 125 are sequentially passed through the first mounting hole 1243 and the second mounting hole 1233, and are plugged into and matched with the liquid receiving pan 113 to limit the circumferential position of the pot rack 12. It can be understood that the pot support legs 125 are plugged into the liquid receiving pan 113 so that the liquid receiving pan 113 limits the pot support legs 125 in the circumferential direction, and the pot support legs 125 are matched with the first mounting hole 1243 and the second mounting hole 1233 so that the pot support legs 125 limit the circumferential direction of the upper cover 124 and the lower cover 123 on the pot rack 12, thereby limiting the circumferential direction of the upper cover 124 and the lower cover 123 on the pot rack 12 by the liquid receiving pan 113, and thus limiting the circumferential direction of the pot rack 12 as a whole.

[0064] This arrangement can prevent the rotation of the pot rack 12 from affecting the pot, thereby preventing the pot from sliding during the heating process, reducing the occurrence of accidental injuries, and ensuring the stability of the cooking process. There are many ways for the pot legs 125 to cooperate with the liquid receiving pan 113. The pot legs 125 can cooperate with the liquid receiving pan 113 by plugging, or by snapping, which are not listed here one by one.

[0065] There are multiple pot legs 125, which are spaced apart along the circumference of the pot stand 12 and cooperate with the burner 11. In this way, the pot stand 12 can be radially limited, thereby preventing the pot stand 12 from sliding in the radial direction during heating, thereby preventing the pot from sliding or tipping over, reducing the occurrence of accidental injuries, and ensuring the stability of the cooking process.

[0066] Further, please also refer to Figures 2 to 3The pot support leg 125 includes a connected support portion 1253 and a support leg 1254. The support portion 1253 is located above the upper cover 124 and is provided with an abutment protrusion 1255 to limit the upper cover 124 away from the lower cover 123. The support leg 1254 is sequentially inserted into the first mounting hole 1243 and the second mounting hole 1233 and engages with the liquid receiving pan 113. This arrangement allows the abutment protrusion 1255 on the support portion 1253 to limit the upper cover 124 away from the lower cover 123, allowing the user to lift the pot stand 12 by grasping the upper cover 124, making it easier for the user to carry the pot stand 12. This also increases the connection area between the pot support leg 125 and the bottom of the pot, improving the stability of the pot support provided by the pot support leg 125, preventing the pot from slipping or tipping during heating, reducing the risk of accidental injury, and ensuring a stable cooking process. When the pot support leg 125 needs to be removed, first unlock the pot support leg 125 from the upper cover 124 and the lower cover 123, and then pull the pot support leg 125 away from the liquid receiving pan 113. The support leg 1254 will pass through the second mounting hole 1233 and the first mounting hole 1243 in turn, thereby detaching from the lower cover 123 and the upper cover 124 in turn.

[0067] The abutting protrusion 1255 can be provided on the radial wall surface of the support portion 1253 relative to the pot holder 12, or on the circumferential wall surface of the support portion 1253 relative to the pot holder 12, without specific limitation herein. There can be multiple abutting protrusions 1255, with the multiple abutting protrusions 1255 being spaced apart and arranged around the circumference of the support portion 1253. The abutting protrusions 1255 can have various shapes, including square or cylindrical, without specific limitation herein.

[0068] Optionally, there are multiple supporting legs 1254. In this way, the contact between the pot support and the liquid receiving pan 113 can be increased, thereby providing more stable support for the pot support 12.

[0069] See also Figure 2 In some embodiments of the present application, a protruding ring 126 is provided on the upper surface of the pot support 12. The protruding ring 126 is spaced apart from the central through hole 121 in the radial direction of the pot support 12. It is understood that the top of the protruding ring 126 is higher than the inner edge of the pot support 12, and the protruding ring 126 and the inner side of the pot support 12 are formed to form a 1262. This arrangement can block outward-flowing smoke, thereby increasing the residence time of the smoke within 1262. In addition, the protruding ring 126 can prevent the heat of the smoke from radiating outward, thereby improving the heat exchange efficiency between the smoke and the pot.

[0070] Further, see Figure 2The fire-proximal protrusion ring 126 includes a first side surface 1261 located near the inner edge of the pot support 12. The first side surface 1261 extends obliquely downward from the convex top of the fire-proximal protrusion ring 126 to the inner edge of the pot support 12 main body. This configuration allows the first side surface 1261 to better guide the smoke from the inner edge of the pot support 12 upward to the convex top of the fire-proximal protrusion ring 126, causing the smoke to tend to flow upward along the first side surface 1261. This increases the impact strength of the smoke on the bottom surface of the pot, thereby further improving the heat exchange efficiency between the smoke and the pot. It should be noted that in one embodiment, the first side surface 1261 may be an inclined surface; of course, in other embodiments, the first side surface 1261 may also be a flat surface, a curved surface, a wavy surface, a serrated surface, or other shapes.

[0071] Considering that during the cooking process, the pot rack 12 will be affected by the pot and shake, if the pot rack 12 abuts against the outer combustion part 112, it will affect the outer combustion part 112, thereby affecting the flame released by the outer combustion part 112. In view of this, please refer to Figure 3 The lower surface of the pot support 12 is spaced apart from the outer combustion portion 112 in the vertical direction. In this way, during the cooking process, the pot support 12 will not affect the outer combustion portion 112, thereby ensuring stability during the cooking process.

[0072] It can be understood that the abutment between the pot rack 12 and the outer combustion part 112 refers to the abutment with the outer ring fire cover 117, and the impact of shaking the pot rack 12 on the outer combustion part 112 can refer to that the pot rack 12 shakes and moves the outer ring fire cover 117, causing the fire holes 118 of the outer ring fire cover 117 to be misaligned with the gas channel 115, resulting in some fire holes 118 of the outer ring fire cover 117 being unable to receive the mixed gas of gas and primary air, thereby affecting the flame released by the outer combustion part 112.
