[0048] 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.

[0049] 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 .

[0050] 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 270 is formed within the burner 200, and both the outer and inner combustion sections 220 and 210 are provided with flame holes 240 that communicate with the gas passage 270. Specifically, a mixture of gas and primary air is ejected from the flame holes 240 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.

[0051] In some structural forms, the burner 200 may include a gas distribution plate (not shown), an inner ring fire cover 250, and an outer ring fire cover 260. The gas distribution plate and the inner ring fire cover 250 are connected to form the inner combustion section 210, and the gas distribution plate and the outer ring fire cover 260 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.

[0052] The pot stand 100 is used in conjunction with the burner 200. The pot stand 100 includes a pot stand body 110 and a heat exchange assembly 120. The pot stand body 110 is arranged in an annular shape and has an air inlet channel 111 provided therein. The air inlet channel 111 has a first 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 heat exchange assembly 120 is installed in the air inlet channel 111 and is provided with at least one air guide channel 121, which extends radially along the pot stand body 110; the air guide channel 121 is connected to the first air inlet 112, the first air outlet 113 and the second air outlet 114.

[0053] 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 160. The central through hole 160 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.

[0054] 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.

[0055] There are many ways to attach the heat exchange assembly 120 to the pot support body 110. The heat exchange assembly 120 and the pot support body 110 may be integrally formed, fixedly attached to the pot support body 110, or removably attached to the pot support body 110, without further limitation. The heat exchange assembly 120 is made of a high-temperature-resistant metal material with a high thermal conductivity, such as iron.

[0056] The cross-section of the air guide channel 121 can have various shapes. The cross-section of the air guide channel 121 can be circular, square, or other shapes, which are not specifically limited here. The air guide channel 121 extends at least radially along the pot support body 110. The air guide channel 121 can extend in a wavy shape or in a straight line, which are not specifically limited here.

[0057] It should be noted that after the secondary air enters the air intake channel 111 through the first air intake port 112, it can reach the first air outlet 113 and the second air outlet 114 through the guide channel. At this time, it can be understood that the secondary air is in full contact with the inner wall surface of the guide channel for heat exchange; after the secondary air enters the air intake channel 111 through the first air intake port 112, it can also reach the first air outlet 113 and the second air outlet 114 through the gap between the heat exchange component 120 and the air intake channel 111. At this time, it can be understood that the secondary air is in full contact with the inner wall surface of the guide channel for heat exchange.

[0058] 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.

[0059] In the embodiment of the present application, when the stove 1000 is in use, the burner 200 will heat the pot rack 100, and secondary air will enter the burner 200 through the air intake channel 111. After entering the air intake channel 111 through the first air inlet 112, the secondary air will enter the air guide channel 121 of the heat exchange component 120. The secondary air is in full contact with the heat exchange component 120 in the air guide channel 121 for heat exchange to preheat the secondary air. The preheated secondary air is mixed with the mixed gas ejected from the fire hole 240 to improve the combustion efficiency and 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.

[0060] Please also refer to Figures 2 to 3In some embodiments of the present application, the heat exchange assembly 120 includes a guide member 122 and a connector 123. The upper or lower surface of the guide member 122 defines at least one first air-guiding groove 122a. The connector 123 is fixedly connected to the pot support body 110 and mounted on the surface of the guide member 122 where the first air-guiding groove 122a is provided, thereby forming an air-guiding channel 121 with the first air-guiding groove 122a. This arrangement allows the connector 123 and the first air-guiding groove 122a to form the air-guiding channel 121. Furthermore, the connector 123 can be connected to the pot support body 110 to secure the heat exchange assembly 120, thereby optimizing the structure of the heat exchange assembly 120.

[0061] The connector 123 and the guide member 122 can be made of the same high-temperature-resistant metal material with a high thermal conductivity coefficient. The connector 123 and the guide member 122 can also be made of different high-temperature-resistant metal materials with a high thermal conductivity coefficient, and no specific limitation is made here. The connector 123 and the guide member 122 can be connected in many ways, and the connector 123 and the guide member 122 can be connected by one or more methods such as welding, screwing, and clamping.

[0062] It should be noted that the first air guide groove 122a is provided through two radially opposite groove walls of the pot support body 110. The first air guide groove 122a can have various shapes, including square, cylindrical, or other shapes, which are not specifically limited here.

[0063] Specifically, see Figure 3 The air inlet channel 111 is annular in shape, and the guide member 122 is wavy and extends along the circumference of the pot stand body 110. Together with the connecting member 123, they enclose a plurality of air guide channels 121 spaced apart along the circumference of the pot stand body 110. A second air guide groove 122b is located between the two air guide grooves. The second air guide groove 122b, along with the upper cover 115 or the lower cover 116, encloses an auxiliary channel 130. This arrangement not only increases the space in the air inlet channel 111, thereby increasing the contact area between the secondary air and the inner wall of the air inlet channel 111, thereby improving the pot stand 100's preheating effect on the secondary air. Furthermore, the wavy guide member 122 increases its surface area, thereby increasing the contact area between the secondary air and the guide member 122, thereby improving the pot stand 100's preheating effect on the secondary air.

[0064] It should be noted that the wavy shape can be understood as meaning that the opposing surfaces of the guide member 122 are respectively provided with a plurality of first air-guiding grooves 122a and a plurality of second air-guiding grooves 122b, with the second air-guiding grooves 122b located between two adjacent first air-guiding grooves 122a, and the first air-guiding grooves 122a and the second air-guiding grooves 122b being arranged sequentially in the circumferential direction of the guide member 122. Preferably, the groove walls of the first air-guiding grooves 122a and the second air-guiding grooves 122b are arc-shaped, which increases the surface area of ​​the guide member 122, thereby increasing the contact area between the secondary air and the guide member 122, and further improving the preheating effect of the pot rack 100 on the secondary air.

[0065] After the secondary air enters the air intake channel 111, it will pass through the air guide channel 121 or the auxiliary channel 130 to the first air outlet 113 and the second air outlet 114. It can be understood that when the secondary air passes through the air guide channel 121, it exchanges heat by contacting the groove wall of the first air guide groove 122a, and when the secondary air passes through the auxiliary channel 130, it exchanges heat by contacting the groove wall of the second air guide groove 122b.

[0066] See also Figure 3 In some embodiments of the present application, the pot stand 100 further includes pot legs 140, which are used to connect the connector 123 to the pot stand body 110 and support the pot. This arrangement simplifies the structure of the pot stand 100 by connecting the connector 123 to the pot stand body 110 via the pot legs 140. The pot legs 140 can connect the connector 123 to the pot stand body 110 through one or more methods, such as welding, screwing, or clamping. This means that the heat exchange assembly 120 is mounted on the pot stand body 110 via the pot bracket.

[0067] 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.

[0068] Specifically, see Figure 2The pot support leg 140 is provided with a mounting portion 141 extending into the air inlet passage 111, and the connecting member 123 is screwed to the mounting portion 141. With this arrangement, the connecting member 123 is screwed to the mounting portion 141. Therefore, if the heat exchange assembly 120 is damaged, the heat exchange assembly 120 can be removed from the pot support body 110 by simply removing the screws. This facilitates maintenance of the heat exchange assembly 120. When the heat exchange assembly 120 needs to be replaced, only the heat exchange assembly 120 needs to be replaced, without having to replace the entire pot support 100. This reduces the maintenance cost of the pot support 100.

[0069] 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.

[0070] Further, see Figure 3 The pot rack body 110 includes an upper cover 115 and a lower cover 116. The upper cover 115 is provided with a first mounting hole 115a in the vertical direction; the lower cover 116 is provided with a second air outlet 114 and a second mounting hole 116a in the vertical direction; the upper cover 115 and the lower cover 116 are surrounded by an air intake channel 111, a first air intake 112 and a first air outlet 113; the pot support leg 140 includes a supporting portion 142 and a supporting leg 143 connected to each other. The supporting portion 142 is located above the upper cover 115 and is provided with an abutting protrusion 144 to limit the upper cover 115 in the direction away from the lower cover 116; the supporting leg 143 is sequentially passed through the first mounting hole 115a and the second mounting hole 116a, and abuts against the burner 200.

[0071] With this arrangement, the upper cover 115 can be limited in position away from the lower cover 116 by the contact protrusion 144 on the support portion 142, so that the user can lift the pot rack body 110 by grasping the upper cover 115, making it easier for the user to carry the pot rack 100. At the same time, the connection area between the pot support legs 140 and the bottom of the pot can be increased, thereby improving the stability of the pot support provided by the pot support legs 140, preventing the pot from sliding or tipping over during heating, reducing the possibility of accidental injury, and ensuring the stability of the cooking process.

[0072] 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 piece 123. 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.

[0073] See also Figure 2 In some embodiments of the present application, the support legs 143 cooperate with the burner 200 to circumferentially limit the position of the pot holder body 110. This arrangement can prevent the rotation of the pot holder 100 from affecting the pot, thereby preventing the pot from sliding during heating, reducing the occurrence of accidental injuries, and ensuring the stability of the cooking process. There are many ways for the support legs 143 to cooperate with the burner 200. The support legs 143 can cooperate with the burner 200 by plugging, or by snapping, which are not listed here.

[0074] 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] Please also refer to Figures 2 to 3 In some embodiments of the present application, the pot rack 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 upper cover 115 and the lower cover 116 enclose an air inlet channel 111, a first air inlet 112, and a first air outlet 113. The first air inlet 112 and the air guide channel 121 at least partially overlap in the vertical direction. This arrangement ensures that after secondary air enters the air inlet channel 111 from the first air inlet 112, it will partially enter the air guide channel 121, thereby ensuring sufficient heat exchange between the secondary air and the heat exchange assembly 120, thereby improving the pot rack 100's preheating effect on the secondary air.

[0076] Specifically, see Figure 3 The surface of the lower cover 116 facing the upper cover 115 is provided with a receiving groove 116b, and the air guide channel 121 is at least partially located within the receiving groove 116b. With this arrangement, the outer upper surface of the lower cover 116 and the upper cover 115 form the first air inlet 112. The air guide channel 121 is partially located within the receiving groove 116b, so that the lower surface of the air guide channel 121 is lower than the outer upper surface of the lower cover 116, thereby ensuring that the first air inlet 112 and the air guide channel 121 at least partially overlap in the vertical direction.

[0077] , further see Figure 2 A second air outlet 114 is formed through the wall of the receiving groove 116b, which is located near the inner side of the pot support body 110. The second air outlet 114 and the air guide channel 121 are at least partially overlapped in the vertical direction. This arrangement allows the secondary air to flow smoothly from the second air outlet 114 into the air passage 230 after passing through the air guide channel 121.

[0078] Considering that the secondary air ejected from the first air outlet 113 is primarily supplied to the fire holes 240 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 simultaneously supplied to the fire holes 240 of the inner combustion section 210 and the fire holes 240 of the outer combustion section 220. For this reason, 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 240 of the inner combustion section 210, thereby improving the combustion efficiency of the cooktop 1000.

[0079] See also Figure 2 In some embodiments of the present application, the upper cover 115 includes a main body 115b and a guide portion 115c. The main body 115b and the lower cover 116 are arranged to form an air inlet passage 111. The guide portion 115c is arranged on the outside of the main body 115b and opposite the outer peripheral wall of the lower cover 116. The guide portion 115c and the lower cover 116 are spaced apart in the radial direction of the main body 115b to form a guide passage 117. The guide passage 117 is connected to the first air inlet 112. With this arrangement, the secondary air first passes through the guide passage 117 and then enters the air inlet passage 111 from the first air inlet 112. Guided by the guide passage 117, the secondary air tends to move upward when entering the first air inlet 112, thereby allowing the secondary air to fully contact the upper wall of the air guide passage 121, thereby improving the preheating effect of the pot rack 100 on the secondary air.

[0080] It can be understood that the upper cover 115 and the lower cover 116 further define a vertically extending guide channel 117 on the outside of the pot support body 110. The upper end of the guide channel 117 communicates with the air inlet channel 111 through the first air inlet 112. Secondary air enters the guide channel 117 and then reaches the first air inlet 112. From there, it enters the air inlet channel 111 and passes through the air guide channel 121 to the first and second air outlets 113 and 114.

[0081] See also Figure 2In some embodiments of the present application, the lower surface of the wok support body 110 is vertically spaced apart from the burner 200 to form a second air inlet 150 that communicates with the air passage 230. With this arrangement, secondary air can enter the air passage 230 through the second air inlet 150, thereby increasing the amount of secondary air entering the air passage 230.

[0082] It should be noted that the lower cover 116 is provided with a guide protrusion, which extends in the direction close to the liquid receiving pan. The distance between the guide protrusion and the liquid receiving pan in the vertical direction is smaller than the distance between the guide portion 115c and the liquid receiving pan in the vertical direction, so that the external air is partially blocked by the guide protrusion when moving toward the second air inlet 150 and enters the guide channel 117, thereby increasing the total amount of secondary air entering the air inlet channel 111.

[0083] See also Figure 1 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.
