DETAILED DESCRIPTION

[0055] 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.

[0056] Please also refer to Figures 1 to 2 , an embodiment of the present application provides a pot rack 100 and a stove 1000 , the stove 1000 includes the pot rack 100 and a burner 200 .

[0057] The burner 200 includes an inner combustion section 210 and an outer combustion section 220 surrounding the inner combustion section 210. An air passage 230 is formed between the inner and outer combustion sections 210, 220. A gas passage 240 is formed within the burner 200, and both the outer and inner combustion sections 220 and 210 are provided with flame holes 250 that communicate with the gas passage 240. Specifically, a mixture of gas and primary air is ejected from the flame holes 250 of the burner 200 and ignited by an ignition device. With the aid of secondary air, a flame is formed, which can be used to heat the cookware.

[0058] In some structural forms, the burner 200 may include a gas distribution plate (not shown), an inner ring fire cover 260, and an outer ring fire cover 270. The gas distribution plate and the inner ring fire cover 260 are connected to form the inner combustion section 210, and the gas distribution plate and the outer ring fire cover 270 are connected to form the outer combustion section 220. The gas distribution plate can be an integrated structure or a split structure, which is not limited in this application.

[0059] The pot support 100 is used in conjunction with the burner 200. The pot support 100 includes a pot support body 110 and a plurality of fins 120. The pot support body 110 is arranged in a ring shape. An air intake channel 111 is provided inside the pot support body 110. The air intake channel 111 has an air inlet 112, a first air outlet 113 and a second air outlet 114. The first air outlet 113 is located above the outer combustion part 220, and the second air outlet 114 is connected to the air passage 230. The plurality of fins 120 are installed on the pot support body 110 and are arranged at intervals along the circumference of the pot support body 110 in the air intake channel 111 to divide the air intake channel 111 into a plurality of air intake sub-channels 111a; the air intake sub-channels 111a are all connected to the air inlet 112, and are connected to the first air outlet 113 and the second air inlet 112.

[0060] Depending on actual needs, the pot support body 110 can be square, circular, or other shapes, without specific limitations here. The pot support body 110 is annular and has a central through hole 150. The central through hole 150 can be circular, square, or other shapes, without specific limitations here. Furthermore, the pot support body 110 can be made of cast iron, enameled, or galvanized materials that have advantages such as high temperature resistance, excellent strength, and good thermal conductivity.

[0061] The cross-section of the air inlet passage 111 can be various. The cross-section of the air inlet passage 111 can be circular, square, or other shapes, which are not specifically limited here. The air inlet passage 111 extends at least radially along the pot support body 110. The air inlet passage 111 can extend in a wavy shape or in a straight line, which are not specifically limited here.

[0062] The fins 120 can have a variety of shapes, including circular, square, or other shapes, without specific limitations herein. The fins 120 can be mounted to the pot support body 110 in a variety of ways, including being integrally formed with the pot support body 110, being fixedly mounted to the pot support body 110, or being removably mounted to the pot support body 110, without specific limitations herein. The fins 120 are made of a high-temperature-resistant metal material with a high thermal conductivity, such as iron.

[0063] It will be appreciated that the multiple air intake sub-channels are spaced apart along the circumference of the wok support body 110 within the air intake channel 111 via the multiple fins 120. When the cooker 1000 is in use, the flame generated by the burner 200 heats the wok support body 110 and the fins 120. When the secondary air enters the air intake channel 111, it flows into each of the air intake sub-channels. Simultaneously, the secondary air fully contacts the wok support body 110 and the fins 120 for heat exchange, thereby preheating the secondary air.

[0064] In the prior art, the pot stand 100 is typically provided with an air intake duct 111 to preheat the secondary air, thereby mixing the preheated secondary air with the mixed gas ejected from the fire holes 250 to improve combustion efficiency. However, the air intake duct 111 of the pot stand 100 in the prior art only exchanges heat through contact between the inner wall surface of the air intake duct 111 and the secondary air. However, the contact area between the air intake duct 111 and the secondary air is relatively small, which prevents the secondary air from being fully preheated. Furthermore, the pot stand 100 in the prior art cannot accurately guide the secondary air to the inner combustion section 210 and the outer combustion section 220.

[0065] In the embodiment of the present application, a plurality of fins 120 are provided in the air intake channel 111, and the plurality of fins 120 divide the air intake channel 111 into a plurality of air intake sub-channels. When the stove 1000 is in use, the burner 200 will heat the pot rack 100, and at the same time, secondary air will enter the burner 200 through the air intake channel 111. After the secondary air enters the air intake channel 111 through the air inlet 112, it will enter each air intake sub-channel respectively. The secondary air is in full contact with the fins 120 in the air intake sub-channel for heat exchange to preheat the secondary air. The preheated secondary air is mixed with the mixed gas ejected from the fire hole 250, thereby improving the combustion efficiency and being able to form a flame with a higher ignition temperature, thereby efficiently and effectively heating the pot, improving the heating efficiency, and thus improving the thermal efficiency of the stove 1000. At the same time, the first air outlet 113 is located above the outer combustion section 220, and the second air outlet 114 is connected to the air passage 230, so that the secondary air can be accurately guided to the outer combustion section 220 and the inner combustion section 210, thereby ensuring that the secondary air is fully in contact with the inner combustion section 210 and the outer combustion section 220, thereby enhancing the combustion effect.

[0066] See also Figure 3 In some embodiments of the present application, the pot rack 100 further includes a connector 130 located within the air inlet passage 111. The connector 130 secures the plurality of fins 120 together. This configuration facilitates mounting the plurality of fins 120 on the pot rack body 110 by securing the plurality of fins 120 together via the connector 130.

[0067] The connector 130 may be connected to the upper surface of each fin 120, the lower surface of each fin 120, or the sidewall of each fin 120 in the circumferential direction of the pot support body 110, without specific limitation here. The connector 130 and the fin 120 may be integrally formed, detachably connected, or fixedly connected, without specific limitation here. It should be noted that the fins 120 are arranged in an annular configuration, and the connector 130 is also arranged in an annular configuration.

[0068] The pot rack 100 further includes pot legs 140, which are used to connect the connector 130 to the pot rack body 110 and to support the pot. Thus, the pot legs 140 connect the connector 130 to the pot rack body 110, thereby simplifying the structure of the pot rack 100. The pot legs 140 can connect the connector 130 to the pot rack body 110 by one or more methods such as welding, screwing, and clamping.

[0069] It should be noted that the pot legs 140 are located at the top of the pot support body 110 and are used to support the bottom of the pot. Optionally, the pot legs 140 can be elongated to increase the connection area between the pot legs 140 and the bottom of the pot. This enhances the stability of the pot support, prevents the pot from sliding or tipping during heating, reduces the risk of accidental injuries, and ensures a stable cooking process. Furthermore, the pot legs 140 can be made of a high-temperature-resistant material such as cast iron, although this embodiment is not limited thereto. There can be multiple pot legs 140, each connected to the top of the pot support body 110 along the circumference of the pot support body 110. This improves the pot support along the circumference of the pot support body 110. The pot support body 110 is placed on the liquid tray of the burner 200 via the pot legs 140.

[0070] Specifically, see Figure 2 The pot support leg 140 is provided with a mounting portion 141 extending into the air inlet passage 111, and the connecting member 130 is screwed to the mounting portion 141. With this arrangement, the connecting member 130 is screwed to the mounting portion 141. Therefore, if the fin 120 or the connecting member 130 is damaged, the connecting member 130 can be removed from the pot support body 110 by simply removing the screws. This facilitates maintenance of the fin 120 or the connecting member 130. When the fin 120 or the connecting member 130 needs to be replaced, only the fin 120 and the connecting member 130 need to be replaced, without having to replace the entire pot support 100. This reduces the maintenance cost of the pot support 100.

[0071] The mounting portion 141 can have a variety of shapes. The mounting portion 141 can be square, cylindrical, or any other shape, and these are not specifically limited here. The mounting portion 141 can be formed by the portion of the pot leg 140 extending into the air inlet passage 111, or by the portion extending out of the air inlet passage 111, extending toward and into the air inlet passage 111. A detailed list of these is omitted here.

[0072] See also Figure 3 In some embodiments of the present application, the pot legs 140 extend through the second air outlet 114 and cooperate with the burner 200 to circumferentially limit the pot support body 110. This arrangement prevents the pot support 100 from rotating and affecting the pot, thereby preventing the pot from rotating during heating, reducing the risk of accidental injury, and ensuring a stable cooking process. Furthermore, the pot legs 140 extend directly from the second air outlet 114, eliminating the need for through-holes in the pot support body 110 to allow the pot legs 140 to extend, thereby simplifying the structure of the pot support body 110.

[0073] It should be noted that the second air outlet 114 must be larger than the pot leg 140 to allow secondary air to enter the air passage 230 through the gap between the second air outlet 114 and the pot leg 140. There are many ways for the pot leg 140 to mate with the burner 200. The pot leg 140 can mate with the burner 200 by plugging or snapping, and these are not listed here.

[0074] See also Figure 3 There are multiple pot legs 140, which are spaced apart along the circumference of the pot support body 110 and cooperate with the burner 200. In this way, the pot support body 110 can be limited in the radial direction, thereby preventing the pot support body 110 from sliding in the radial direction during the heating process, thereby preventing the pot from sliding or tipping over, reducing the occurrence of accidental injuries, and ensuring the stability of the cooking process.

[0075] See also Figure 3 In some embodiments of the present application, the pot stand body 110 includes an upper cover 115 and a lower cover 116. The lower cover 116 is provided with a second air outlet 114. The pot legs 140 connect the upper and lower covers 115, 116. The upper and lower covers 115, 116 enclose an air inlet channel 111, which is provided with an air inlet 112 and a first air outlet 113. This arrangement connects the upper and lower covers 115, 116 via the pot legs 140, eliminating the need for an additional connecting structure to connect the upper and lower covers 115, 116, thereby simplifying the structure of the pot stand 100.

[0076] The upper cover 115 and the lower cover 116 can be fixedly connected to the pot legs 140 by one or more methods such as welding, screw connection, and clamping. Here, the specific connection method of the upper cover 115 and the lower cover 116 is not limited.

[0077] Specifically, see Figure 3 The upper cover 115 is vertically penetrated by a first mounting hole 115a, and the connecting member 130 is vertically penetrated by a second mounting hole 131. The pot legs 140 are sequentially inserted through the first mounting hole 115a and the second mounting hole 131 and fixedly connected to the lower cover 116. This arrangement ensures that the fins 120 are stably located within the air inlet passage 111 formed by the upper and lower covers 115, 116, preventing the fins 120 from separating from the air inlet passage 111.

[0078] Further, see Figure 3 The pot support leg 140 includes a connected support portion 142 and a support leg 143. The support portion 142 is located above the upper cover 115 and is provided with an abutment protrusion 144 to limit the upper cover 115 in a direction away from the lower cover 116. The support leg 143 is sequentially inserted through the first mounting hole 115a and the second mounting hole 131 and is fixedly connected to the lower cover 116. This arrangement allows the abutment protrusion 144 on the support leg 143 to limit the upper cover 115 in a direction away from the lower cover 116, allowing the user to lift the pot stand body 110 by grasping the upper cover 115, making it easier for the user to carry the pot stand 100. This also increases the connection area between the pot support leg 140 and the bottom of the pot, improving the stability of the pot support provided by the pot support leg 140, preventing the pot from slipping or tipping during heating, reducing the risk of accidental injury, and ensuring a stable cooking process.

[0079] Preferably, the mounting portion 141 can be set on the abutting protrusion 144 and extend into the air intake channel 111 through the first mounting hole 115a to be connected to the connecting member 130. This can reduce the need to set a through hole in the upper cover 115 for the mounting portion 141 to pass through the upper cover 115 and extend into the air intake channel 111, thereby simplifying the structure of the upper cover 115.

[0080] Please also refer to Figures 2 to 3In some embodiments of the present application, the pot rack body 110 includes an upper cover 115 and a lower cover 116. The upper cover 115 has a first mounting section 115b and a first air outlet section 115c connected to each other; the lower cover 116 has a second mounting section 116a, a second air outlet section 116b and a third air outlet section 116c connected in sequence, and the air outlet section is provided with a second air outlet 114; the first mounting section 115b and the second mounting section 116a form an air inlet channel 111 and form an air inlet 112; the first air outlet section 115c and the third air outlet section 116c form a second air outlet 114; the second air outlet section 116b is inclined from the air inlet direction of the air inlet channel 111 toward the direction close to the pot rack body 110. With such a configuration, the secondary air enters the air intake channel 111 from the air intake port 112 and contacts the second air outlet section 116b, and partially enters the first air outlet 113 along the guidance of the second air outlet section 116b, and partially enters the air passage 230 from the second air outlet 114, so that the secondary air can be better ejected from the first air outlet 113.

[0081] Please also refer to Figures 3 and 4 Furthermore, a plurality of spoilers 117 are protruding from the surface of the third air outlet section 116c facing the upper cover 115. The spoilers 117 have exhaust passages 117a extending through the inner and outer sides of the spoilers 117. It is understood that when a fluid encounters an obstacle during its flow, several rotating vortices are formed behind the obstacle (the formation principle of crescent-shaped sand dunes). Furthermore, when the fluid passes through narrow passages such as pipes and channels, the changes in flow velocity and friction can also form rotating vortices.

[0082] In this embodiment, by providing a spoiler 117 having an exhaust channel 117a, secondary air passing through the spoiler 117 forms a vortex at the spoiler 117. The secondary air discharged through the exhaust channel 117a also forms a vortex, which can enhance the disturbance of the secondary air, thereby extending the residence time of the secondary air in the third air outlet section 116c, thereby improving the preheating effect of the pot rack 100 on the secondary air. At the same time, the secondary air flowing toward the first air outlet 113 in multiple directions can be disturbed by the spoiler 117, allowing more secondary air to reside in the third air outlet section 116c for a longer period of time, thereby improving the preheating effect of the pot rack 100 on the secondary air. The spoiler 117 can be integrally formed with the lower cover 116, or it can be connected to the lower cover 116 by welding, snapping, threading, riveting, or other means.

[0083] Specifically, see Figure 4The spoiler 117 includes two protrusions 117b spaced circumferentially around the pot support body 110 to form an exhaust channel 117a. These protrusions 117b are arranged gradually away from each other in the air intake direction of the air intake channel 111. It can be understood that the first opening of the exhaust channel 117a, facing inward from the pot support body 110, is smaller than the second opening of the exhaust channel 117a, facing outward from the pot support body 110. Secondary air enters the exhaust channel 117a through the first opening and exits through the second opening. This arrangement, where the first opening is narrower than the second opening, creates a pressure difference between the first and second openings. This pressure difference causes the secondary air in the exhaust channel 117a to more easily form vortices, thereby enhancing the disturbance of the secondary air and improving the preheating effect of the pot support 100. The protrusions 117b can have various shapes, including wavy or plate-shaped, without specific limitations herein.

[0084] In some embodiments of the present application, the spacing between two adjacent spoilers 117 is greater than the circumferential width of the exhaust channel 117a along the pot support body 110. It is understood that when the secondary air is discharged, it may also be discharged from the gap between two adjacent spoilers 117. Compared to the gap between two adjacent spoilers 117, the exhaust channel 117a is relatively narrow, so that the pressure of the secondary air flowing through the gap between two adjacent spoilers 117 is lower than the pressure of the secondary air flowing through the exhaust channel 117a. This creates a pressure difference between the inside and outside of the exhaust channel 117a. Driven by the pressure difference, the secondary air is more likely to form vortices, which can enhance the disturbance of the secondary air, thereby extending the residence time of the secondary air in the third air outlet section 116c, and improving the preheating effect of the pot support 100 on the secondary air.

[0085] Please also refer to Figures 1 to 3 In some embodiments of the present application, the air inlet passage 111 extends along the circumference of the wok support body 110. This configuration increases the space of the air inlet passage 111, thereby increasing the contact area between the secondary air and the inner wall of the air inlet passage 111, thereby improving the preheating effect of the wok support 100 on the secondary air, thereby improving the combustion performance of the cooktop 1000.

[0086] Optionally, the air inlet 112 extends along the circumference of the pot support body 110 to be arranged in an annular shape. In this way, the air inlet 112 is enlarged, thereby increasing the amount of secondary air entering the air inlet channel 111 through the air inlet 112 .

[0087] Optionally, the first air outlet 113 extends along the circumference of the pot rack body 110 to be arranged in a ring shape. Such an arrangement allows the secondary air to be evenly provided to the various fire holes 250 of the outer combustion part 220 after passing through the air inlet channel 111, thereby ensuring that the flame intensity generated by each fire outlet of the outer combustion part 220 is consistent, thereby evenly heating the pot.

[0088] Optionally, the second air outlet 114 extends along the circumference of the pot rack body 110 to be arranged in a ring shape. Such an arrangement allows the secondary air to be evenly provided to the air passage 230 after passing through the air inlet channel 111, so that the secondary air received by each fire outlet of the inner combustion section 210 and the outer combustion section 220 is consistent, thereby ensuring that the flame intensity generated by each fire outlet of the inner combustion section 210 and the outer combustion section 220 is consistent, and thus the pot is evenly heated.

[0089] Optionally, a plurality of air inlets 112 are provided, and the plurality of air inlets 112 are spaced apart along the circumference of the pot rack body 110 . This arrangement increases the number of air inlets 112 , thereby increasing the amount of secondary air entering the air inlet channel 111 through the air inlet 112 .

[0090] Optionally, a plurality of first air outlets 113 are provided, and the plurality of first air outlets 113 are arranged at intervals along the circumference of the pot rack body 110. Such an arrangement allows the secondary air to be evenly provided to the various fire holes 250 of the outer combustion part 220 after passing through the air inlet channel 111, thereby ensuring that the flame intensity generated by each fire outlet of the outer combustion part 220 is consistent, thereby evenly heating the pot.

[0091] Optionally, a plurality of second air outlets 114 are provided, and the plurality of second air outlets 114 are arranged at intervals along the circumference of the pot rack body 110. Such an arrangement allows the secondary air to be evenly provided to the air passage 230 after passing through the air inlet channel 111, so that the secondary air received by each fire outlet of the inner combustion section 210 and the outer combustion section 220 is consistent, thereby ensuring that the flame intensity generated by each fire outlet of the inner combustion section 210 and the outer combustion section 220 is consistent, and thus the pot is evenly heated.

[0092] See also Figure 2Considering that the secondary air ejected from the first air outlet 113 is primarily supplied to the fire holes 250 of the outer combustion section 220, while the secondary air ejected from the second air outlet 114 enters the air passage 230, the secondary air ejected from the second air outlet 114 is supplied to both the fire holes 250 of the inner combustion section 210 and the fire holes 250 of the outer combustion section 220. Therefore, the cross-section of the first air outlet 113 is smaller than that of the second air outlet 114. This arrangement ensures that the total amount of secondary air entering the air passage 230 through the second air outlet 114 is greater than the total amount of air entering the outer combustion section 220 through the first air outlet 113. This ensures that sufficient secondary air is provided to the fire holes 250 of the inner combustion section 210, thereby improving the combustion efficiency of the cooktop 1000.

[0093] See also Figure 2 Considering that the pot support 100 may be affected by the pot during cooking, and that if the pot support 100 abuts the outer combustion part 220, it will affect the outer combustion part 220, thereby affecting the flame released by the outer combustion part 220, in view of this, the pot support 100 is arranged vertically apart from the outer combustion part 220. This arrangement prevents the pot support 100 from affecting the outer combustion part 220 during cooking, thus ensuring stability during cooking.
