Description

Technical Field

[0001] The utility model relates to the technical field of kitchenware, in particular to a pot support assembly and a burner. Background Art

[0002] In actual use of existing gas stoves, since the pot is placed on a pot support for heating, there is a certain space between the pot and the burner. In this way, in addition to being used to heat the pot, a considerable portion of the heat energy generated by the combustion of the gas escapes into the surrounding environment, causing energy waste.

[0003] In order to improve the combustion efficiency, in the prior art, there is a pot support structure that uses an energy-gathering cover including an annular cover body and an outer cover to enable both the inner and outer rings to fully burn. Although the above pot support structure improves the combustion efficiency to a certain extent by focusing energy, the structure of the energy-gathering plate or the energy-gathering cover is complex and the cost is high. In addition, during the cooking process, harmful substances such as CO generated by incomplete combustion are mixed and discharged, and the reaction is slow, which also has serious harm to the human body and the environment. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the utility model, a pot support assembly is provided, and the technical solution is as follows.

[0005] The pot support assembly comprises a first plate and a second plate, which are arranged up and down with a cavity formed therebetween, and a plurality of smoke guides are arranged on the outer surface of the first plate away from the second plate at intervals along the circumferential direction of the first plate, and the smoke guides protrude from the outer surface in a direction away from the second plate or are recessed in the outer surface in a direction close to the second plate.

[0006] The pot support assembly of the utility model, on the one hand, improves the energy gathering function by forming a cavity through the two plates, thereby improving the combustion efficiency, and has a simple structure and reduces the cost; on the other hand, a smoke guide portion is arranged on the first plate, and the smoke guide portion can effectively separate harmful substances such as CO that are not completely burned, so that the reaction is accelerated and heat is released. The pot support assembly increases the temperature by absorbing this part of heat, thereby improving energy efficiency and reducing harm to the human body and the environment.

[0007] Exemplarily, there is a maximum distance H between the smoke guide and the outer surface, and the maximum distance H is 2 mm to 4 mm. Within this distance range, the smoke guide protrudes from the outer surface in a direction away from the second disk or is recessed in the outer surface in a direction close to the second disk, which can effectively separate incompletely burned CO and other harmful substances, accelerate their reaction, and release heat. The pot support assembly absorbs this part of the heat to increase the temperature, thereby improving energy efficiency and reducing harm to the human body and the environment.

[0008] Exemplarily, the smoke guide has a width L in the circumferential direction of the first disk, and the width L is 16 mm to 20 mm. The smoke guide has a good guiding effect within this width range, and the pot support assembly can absorb the heat dissipated by high-temperature smoke radiation when guiding the smoke, thereby increasing the temperature.

[0009] For example, the first plate has a first flat portion and a second flat portion at both ends, and a plurality of smoke guides are located between the first flat portion and the second flat portion. With this arrangement, the smoke guide has the best guiding effect, and is convenient for forming a sealed cavity, thereby improving the effect of heat insulation and energy concentration.

[0010] Exemplarily, the first plate includes a first arc portion, a second arc portion and a third arc portion, the first arc portion is connected to the first flat portion, the third arc portion is connected to the second flat portion, the second arc portion is connected between the first arc portion and the third arc portion, and the first arc portion and the third arc portion are tangent to the second arc portion respectively. Such an arrangement not only guides the high-temperature smoke to radiate and conduct heat to the bottom of the pot, reducing heat spillage, but also effectively forms a cavity to isolate heat transfer, thereby improving energy efficiency.

[0011] For example, the first arc portion has a radius R1, which is 20 mm to 25 mm. The radius of the first arc portion is within this range, which not only guides the high-temperature smoke to radiate and conduct heat to the bottom of the pot, reducing heat spillover, but also effectively forms a cavity to isolate heat transfer, thereby improving energy efficiency.

[0012] For example, the second arc portion has a radius R2, and the radius R2 is 50 mm to 60 mm. When the radius of the second arc portion is within this range, it not only guides the high-temperature smoke to radiate and conduct heat to the bottom of the pot, reducing heat spillage, but also effectively forms a cavity to isolate heat transfer, thereby improving energy efficiency.

[0013] For example, the third arc portion has a radius R3, and the radius R3 is 8 mm to 10 mm. When the radius of the third arc portion is within this range, it not only guides the high-temperature smoke to radiate and conduct heat to the bottom of the pot, reducing heat spillage, but also effectively forms a cavity to isolate heat transfer, thereby improving energy efficiency.

[0014] Exemplarily, the second plate has a third flat portion and a fourth flat portion at both ends, the first flat portion is attached to the third flat portion, and the second flat portion is attached to the fourth flat portion. This arrangement facilitates the formation of a sealed cavity and improves the heat insulation and energy gathering effect.

[0015] Exemplarily, the second plate includes a vertical portion, a fourth arc portion and a fifth arc portion, the vertical portion is connected to the third flat portion and is perpendicular to the third flat portion, the fifth arc portion is connected to the fourth flat portion, the fourth arc portion is connected between the vertical portion and the fifth arc portion, and the fourth arc portion is tangent to the fifth arc portion. Such an arrangement can effectively form a cavity to prevent heat from being transferred to the second plate, thereby preventing heat from being lost, and can also reduce the volume of the pot support assembly, thereby saving space.

[0016] Exemplarily, the vertical portion has a length D, which is 6 mm to 8 mm. Within this length range, the vertical portion can effectively form a cavity to prevent heat from being transferred to the second pan, thereby preventing heat from being lost, and can also reduce the volume of the pot support assembly, thereby saving space.

[0017] Exemplarily, the fourth arc portion has a radius R4, and the radius R4 is 21 mm to 24 mm. When the radius of the fourth arc portion is within this range, a cavity can be effectively formed to prevent heat from being transferred to the second disk, thereby preventing heat from being lost.

[0018] Exemplarily, the fifth arc portion has a radius R5, and the radius R5 is 16 mm to 19 mm. When the radius of the fifth arc portion is within this range, a cavity can be effectively formed to prevent heat from being transferred to the second disk, thereby preventing heat from being lost.

[0019] Exemplarily, the first flat portion has a length S1, and the length S1 is 2 mm to 5 mm. The first flat portion is within this length range, which facilitates the formation of a sealed cavity and improves the effect of heat insulation and energy collection.

[0020] Exemplarily, the third flat portion has a length S3, and the length S3 is 2 mm to 5 mm. The third flat portion is within this length range, which facilitates the formation of a sealed cavity and improves the effect of heat insulation and energy collection.

[0021] Exemplarily, the second flat portion has a length S2, and the length S2 is 3 mm to 6 mm. The second flat portion is within this length range, which facilitates the formation of a sealed cavity and improves the effect of heat insulation and energy collection.

[0022] Exemplarily, the fourth flat portion has a length S4, and the length S4 is 3 mm to 6 mm. The fourth flat portion is within this length range, which facilitates the formation of a sealed cavity and improves the effect of heat insulation and energy gathering.

[0023] Exemplarily, the pot support assembly further includes a soup plate, a first pot support claw and a second pot support claw, the first pot support claw is connected to the outer surface, the second plate has an outer plate surface away from the first plate, one end of the second pot support claw is connected to the outer plate surface, and the other end of the second pot support claw is connected to the soup plate. In this arrangement, the first plate is connected to the first pot support claw to meet the performance requirements, and the flame burns to a relatively thin part, so that the smoke is relatively low, which is convenient for guiding the smoke; the second plate is connected to the soup plate through the second pot support claw, and the contact area is small, so that the heat transfer range is small, reducing heat loss.

[0024] For example, there is a gap between the outer plate surface and the soup plate for air circulation. This arrangement satisfies the need for secondary air replenishment without affecting the cooling of the soup plate.

[0025] For example, the gap has a height d in the installation direction of the pot support assembly, and the height d is 5 mm to 8 mm. Within this height range, the gap satisfies the need for supplementation of secondary air without affecting the cooling of the soup plate, avoiding the situation where the height is too high, resulting in excessive supplementation of secondary air, slow flow rate, and affecting the cooling of the soup plate, and avoiding the situation where the height is too low, resulting in insufficient supplementation of secondary air.

[0026] Exemplarily, the second plate is provided with a vent hole, and the cavity is connected to the external space through the vent hole. This arrangement avoids the phenomenon that the first plate or the second plate is deformed due to the influence of thermal expansion and contraction of the gas in the cavity.

[0027] Exemplarily, the vent hole has a diameter D1 of 2 mm to 5 mm. Within this range, the vent hole ensures that the gas in the cavity is connected with the external gas, thereby effectively preventing the gas in the cavity from being deformed by thermal expansion and contraction, causing the first plate or the second plate to deform.

[0028] According to one aspect of the utility model, a burner is provided, the burner comprising an outer ring fire cover and the pot support assembly as described above, the pot support assembly being arranged outside the outer ring fire cover. Since the pot support assembly as described above has the above beneficial effects, the burner comprising the pot support assembly as described above also has the above beneficial effects, which will not be described one by one here.

[0029] Exemplarily, the pot support assembly has a pot support inner ring, the outer ring fire cover has a fire hole outer ring, and there is a gap L1 between the pot support inner ring and the fire hole outer ring, and the gap L1 is 5mm to 20mm. When the gap between the pot support inner ring and the fire hole outer ring is within this range, the smoke emission is low and the thermal efficiency is high.

[0030] Exemplarily, the inner ring of the pot support has an inner ring top, the outer ring of the fire hole has an outer ring top, and there is a distance d1 between the inner ring top and the outer ring top, and d1 is 5mm to 15mm. When the distance between the inner ring top and the outer ring top is within this range, the smoke emission is low and the thermal efficiency is high.

[0031] A series of simplified concepts are introduced in the utility model content, which will be further described in detail in the detailed implementation section. The utility model content section does not mean to attempt to define the key features and essential technical features of the technical solution claimed for protection, nor does it mean to attempt to determine the scope of protection of the technical solution claimed for protection.

DETAILED DESCRIPTION

[0042] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0043] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0044] In view of the problem that the prior art requires high costs to improve combustion efficiency, the utility model provides a pot support assembly. In order to understand the present invention as a whole, a burner using the pot support assembly is first described.

[0045] For a household gas stove, its burner usually has an outer ring fire cover, an inner ring fire cover and a pot support assembly, and the outer ring fire cover and the inner ring fire cover form at least two rings of flames, thereby providing a variety of flame modes when the user uses it. Correspondingly, the burner further includes a large fire distributor and a small fire distributor, as well as a large fire venturi and a small fire venturi. The small fire distributor is arranged at the center of the large fire distributor. The outer ring fire cover and the inner ring fire cover are respectively covered on the large fire distributor and the small fire distributor, and the outer ring fire cover is located on the periphery of the inner ring fire cover. The large fire venturi and the small fire venturi are respectively connected to the large fire distributor and the small fire distributor. The large fire distributor, the outer ring fire cover and the large fire venturi form a large fire mixing chamber. The small fire distributor, the inner ring fire cover and the small fire venturi form a small fire mixing chamber. The pot support assembly is arranged on the periphery of the outer ring fire cover to support the pot.

[0046] The following will combine Figures 1 to 6 A pot support assembly according to an embodiment of the utility model is described.

[0047] See also Figure 1 The pot support assembly 10 may include a first plate 110 and a second plate 120. The first plate 110 and the second plate 120 are arranged up and down and a cavity 130 may be formed therebetween. A plurality of smoke guides 112 may be arranged at intervals along the circumferential direction of the first plate 110 on an outer surface 111 of the first plate 110 away from the second plate 120. The smoke guides 112 may protrude from the outer surface 111 in a direction away from the second plate 120 or be recessed in the outer surface 111 in a direction close to the second plate 120.

[0048] The pot support assembly 10 of the utility model, on the one hand, improves the energy gathering function by forming the cavity 130 through the two plates, thereby improving the combustion efficiency, and has a simple structure and reduces the cost; on the other hand, a smoke guide portion 112 is provided on the first plate 110, and the smoke guide portion 112 can effectively separate the harmful substances such as CO that are not completely burned, so that the reaction is accelerated and heat is released. The pot support assembly 10 absorbs this part of heat to increase the temperature, thereby improving energy efficiency and reducing the harm to the human body and the environment.

[0049] Further, see Figure 3 Along the circumferential direction of the pot support assembly 10, 2 to 4 smoke guides 112 can be set within every 90 degrees. When 3 smoke guides 112 are set within every 90 degrees, the guide effect is best and the smoke separation effect is best.

[0050] Combined with reference Figure 1 and Figure 2 , the middle part of the smoke guide 112 may protrude from the outer surface 111 in the direction away from the second disk 120 or may be recessed in the outer surface 111 in the direction close to the second disk 120. The smoke guide 112 protrudes from the outer surface 111 in the direction away from the second disk 120. Since the smoke contains gases of different weights, taking CO and CO2 as an example, the weight of CO2 is heavier than the weight of CO, CO will flow along the protruding section 1121 of the smoke guide 112 protruding from the outer surface 111, and CO2 will flow along the main body section 1122 of the smoke guide 112 and the outer surface 111 located on the same circumferential surface. In an embodiment not shown, the smoke guide is recessed in the outer surface in the direction close to the second disk. Taking CO and CO2 as an example again, CO will flow along the main body section of the smoke guide and the outer surface located on the same circumferential surface, and CO2 will flow along the recessed section of the smoke guide recessed in the outer surface. In this way, smoke separation is achieved, the reaction is accelerated, and the energy gathering effect is improved.

[0051] See also Figure 2, there may be a maximum distance H between the smoke guide 112 and the outer surface 111 (i.e., the maximum distance H between the protruding section 1121 or the recessed section and the main section 1122), and the maximum distance H may be 2 mm to 4 mm. For example, the maximum distance H may be 2 mm, 3 mm, 4 mm, etc. When the maximum distance H is 3 mm, the smoke separation effect is best. Within this distance range, the smoke guide 112 protrudes from the outer surface 111 in the direction away from the second plate 120 or is recessed in the outer surface 111 in the direction close to the second plate 120, which can effectively separate incompletely burned CO and other harmful substances, accelerate their reaction, and release heat. The pot support assembly 10 absorbs this part of the heat to increase the temperature, thereby improving energy efficiency and reducing harm to the human body and the environment.

[0052] See again Figure 3 The smoke guide portion 112 may have a width L in the circumferential direction of the first plate 110, and the width L may be 16 mm to 20 mm. For example, the width L may be 16 mm, 18 mm, 20 mm, etc. When the width L is 18 mm, the smoke guide effect is the best. The smoke guide portion 112 has a good guide effect within this width range, and the pot support assembly 10 can absorb the heat dissipated by the high-temperature smoke radiation when guiding the smoke, thereby increasing the temperature.

[0053] See again Figure 1 , the two ends of the first plate 110 may have a first flat portion 113 and a second flat portion 114, respectively, and a plurality of smoke guides 112 may be located between the first flat portion 113 and the second flat portion 114. With such a configuration, the smoke guide 112 has the best guiding effect, and is convenient for forming a sealed cavity 130, thereby improving the effect of heat insulation and energy gathering. The smoke overflows from the inner ring fire cover 30 and the outer ring fire cover 20, that is, the smoke diffuses outward from the middle of the pot support assembly 10, and the two ends of the smoke guide 112 are respectively connected to the first flat portion 113 and the second flat portion 114, which conforms to the flow direction of the smoke and has a better guiding effect.

[0054] Combined with reference Figure 5 and Figure 6, the first plate 110 may include a first arc portion 115, a second arc portion 116 and a third arc portion 117. The first arc portion 115 may be connected to the first flat portion 113, the third arc portion 117 may be connected to the second flat portion 114, the second arc portion 116 may be connected between the first arc portion 115 and the third arc portion 117, and the first arc portion 115 and the third arc portion 117 may be tangent to the second arc portion 116 respectively. Such an arrangement not only guides the high-temperature smoke to radiate and conduct heat to the bottom of the pot, reducing heat spillage, but also effectively forms a cavity 130 to isolate the transfer of heat, thereby improving energy efficiency. The first arc portion 115, the second arc portion 116, the third arc portion 117, the first flat portion 113 and the second flat portion 114 may be integrally formed, and of course, the situation of being connected separately is not excluded. Specifically, the first arc portion 115 can be bent in a direction away from the second plate 120, the second arc portion 116 can be bent in a direction away from the second plate 120, and the third arc portion 117 can be bent in a direction close to the second plate 120. In this way, the cavity 130 is enlarged as much as possible, the combustion efficiency is improved, and the third arc portion 117 forms a collection groove. When overflow liquid splashes on the first arc portion 115 or the second arc portion 116 in the pot, it will flow down along the first arc portion 115 or the second arc portion 116 to the collection groove, thereby effectively preventing the overflow liquid from flowing inwardly toward the fire cover, avoiding the problem of flameout and fire hole blockage. Of course, it is not ruled out that the first plate 110 has other bending forms.

[0055] See also Figure 6 , the first arc-shaped portion 115 may have a radius R1, and the radius R1 may be 20 mm to 25 mm. For example, the radius R1 may be 20 mm, 23 mm, 25 mm, etc. When the radius R1 is 23 mm, the effect of guiding the high-temperature smoke to radiate and conduct heat to the bottom of the pot is the best. When the radius of the first arc-shaped portion 115 is within this range, it not only guides the high-temperature smoke to radiate and conduct heat to the bottom of the pot, reducing heat spillage, but also effectively forms a cavity 130 to isolate the transfer of heat, thereby improving energy efficiency.

[0056] See again Figure 6 , the second arc portion 116 may have a radius R2, and the radius R2 may be 50 mm to 60 mm. For example, the radius R2 may be 50 mm, 55 mm, 60 mm, etc. When the radius R2 is 55 mm, the effect of guiding the high-temperature smoke to radiate and conduct heat to the bottom of the pot is the best. When the radius of the second arc portion 116 is within this range, it not only guides the high-temperature smoke to radiate and conduct heat to the bottom of the pot, reducing heat spillage, but also effectively forms a cavity 130 to isolate the transfer of heat, thereby improving energy efficiency.

[0057] See again Figure 6The third arc portion 117 may have a radius R3, and the radius R3 may be 8 mm to 10 mm. For example, the radius R3 may be 8 mm, 9 mm, 10 mm, etc. When the radius R3 is 10 mm, the effect of blocking the overflow from flowing inward to the fire cover is the best. When the radius of the third arc portion 117 is within this range, it not only guides the high-temperature smoke to radiate and conduct heat to the bottom of the pot, reducing heat overflow, but also effectively forms a cavity 130 to isolate the transfer of heat, thereby improving energy efficiency.

[0058] Combined with reference Figure 1 and Figure 6 , the two ends of the second plate 120 may have a third flat portion 121 and a fourth flat portion 122, respectively, the first flat portion 113 may be attached to the third flat portion 121, and the second flat portion 114 may be attached to the fourth flat portion 122. Such an arrangement facilitates the formation of a sealed cavity 130 and improves the heat insulation and energy gathering effect. Specifically, the first flat portion 113 and the third flat portion 121 may be welded, and the second flat portion 114 and the fourth flat portion 122 may be welded, so as to easily form a sealed cavity 130. Of course, it is not excluded that the first flat portion 113 and the third flat portion 121 have other connection methods, nor is it excluded that the second flat portion 114 and the fourth flat portion 122 have other connection methods.

[0059] Again, refer to Figure 5 and Figure 6 , the second plate 120 may include a vertical portion 123, a fourth arc portion 124 and a fifth arc portion 125. The vertical portion 123 may be connected to the third flat portion 121 and perpendicular to the third flat portion 121, the fifth arc portion 125 may be connected to the fourth flat portion 122, the fourth arc portion 124 may be connected between the vertical portion 123 and the fifth arc portion 125, and the fourth arc portion 124 and the fifth arc portion 125 may be tangent. Such an arrangement can effectively form the cavity 130, prevent heat from being transferred to the second plate 120, thereby preventing heat from being lost, and reduce the volume of the pot support assembly 10, thereby saving space. The vertical portion 123, the fourth arc portion 124, the fifth arc portion 125, the third flat portion 121 and the fourth flat portion 122 may be integrally formed, and of course, the situation of being connected separately is not excluded. Specifically, the fourth arc portion 124 may be bent in a direction away from the first plate 110, and the fifth arc portion 125 may be bent in a direction away from the first plate 110. In this way, the cavity 130 is expanded as much as possible to improve the combustion efficiency. Of course, it is not excluded that the second plate 120 has other bending forms.

[0060] Again, refer to Figure 5 and Figure 6The vertical portion 123 may have a length D, and the length D may be 6 mm to 8 mm. For example, the length D may be 6 mm, 7 mm, 8 mm, etc. When the length D is 7 mm, the effect of preventing heat transfer is best. Within this length range, the vertical portion 123 can effectively form the cavity 130 to prevent heat from being transferred to the second plate 120, thereby preventing heat from being lost, and can also reduce the volume of the pot support assembly 10, thereby saving space.

[0061] Again, refer to Figure 5 and Figure 6 The fourth arc portion 124 may have a radius R4, and the radius R4 may be 21 mm to 24 mm. For example, the radius R4 may be 21 mm, 23 mm, 24 mm, etc. When the radius R4 is 23 mm, the effect of preventing heat transfer is best. When the radius of the fourth arc portion 124 is within this range, the cavity 130 can be effectively formed to prevent heat from being transferred to the second disk 120, thereby preventing heat from being lost.

[0062] Again, refer to Figure 5 and Figure 6 The fifth arc portion 125 may have a radius R5, and the radius R5 may be 16 mm to 19 mm. For example, the radius R5 may be 16 mm, 18 mm, 19 mm, etc. When the radius R5 is 18 mm, the effect of preventing heat transfer is best. When the radius of the fifth arc portion 125 is within this range, the cavity 130 can be effectively formed to prevent heat from being transferred to the second disk 120, thereby preventing heat from being lost.

[0063] See again Figure 1 The first flat portion 113 may have a length S1, which may be 2 mm to 5 mm. For example, the length S1 may be 2 mm, 3 mm, 5 mm, etc. When the length S1 is 3 mm, the sealing effect of the connection with the second plate 120 is the best. The first flat portion 113 is within this length range, which facilitates the formation of the sealed cavity 130 and improves the effect of heat insulation and energy gathering.

[0064] See again Figure 1 The third flat portion 121 may have a length S3, and the length S3 may be 2 mm to 5 mm. For example, the length S3 may be 2 mm, 3 mm, 5 mm, etc. When the length S3 is 3 mm, the sealing effect of the connection with the first plate 110 is the best. The third flat portion 121 is within this length range, which facilitates the formation of the sealed cavity 130 and improves the effect of heat insulation and energy gathering.

[0065] See again Figure 1The second flat portion 114 has a length S2, and the length S2 is 3 mm to 6 mm. For example, the length S2 can be 3 mm, 5 mm, 6 mm, etc. When the length S2 is 5 mm, the sealing effect of connecting with the second plate 120 is the best. The second flat portion 114 is within this length range, which facilitates the formation of the sealed cavity 130 and improves the effect of heat insulation and energy gathering.

[0066] See again Figure 1 The fourth flat portion 122 may have a length S4, which may be 3 mm to 6 mm. For example, the length S4 may be 3 mm, 5 mm, 6 mm, etc. When the length S4 is 5 mm, the sealing effect of the connection with the first plate 110 is the best. The fourth flat portion 122 is within this length range, which facilitates the formation of the sealed cavity 130 and improves the effect of heat insulation and energy gathering.

[0067] Combined with reference Figures 1 to 6 The pot support assembly 10 may further include a soup plate 140, a first pot support claw 150 and a second pot support claw 160. The first pot support claw 150 may be connected to the outer surface 111. The second plate 120 may have an outer plate surface 126 away from the first plate 110, one end of the second pot support claw 160 may be connected to the outer plate surface 126, and the other end of the second pot support claw 160 may be connected to the soup plate 140. The second pot support claw 160 may be used to support the first plate 110 and the second plate 120. The first pot support claw 150 may be welded to the outer surface 111, and the second pot support claw 160 may be welded to the outer plate surface 126. Of course, other connection methods are not excluded. The first pot support claw 150 and the second pot support claw 160 may be located on the same plane. The soup plate 140 may be provided with an insertion groove 141, and the second pot support claw 160 may be inserted into the insertion groove 141, so that the soup plate 140 can be easily disassembled for cleaning. The soup plate 140 and the second pot rack claw 160 can also be connected by bonding or welding. In this way, the first plate 110 and the first pot rack claw 150 are connected to meet the performance requirements, and the flame burns a relatively thin part, so that the smoke is relatively low, which is convenient for guiding the smoke; the second plate 120 is connected to the soup plate 140 through the second pot rack claw 160, and the contact area is small, so the heat transfer range is small, and the heat loss is reduced.

[0068] Further, a plurality of first pot support claws 150 may be provided, and the plurality of first pot support claws 150 may be arranged at intervals along the circumferential direction of the outer surface 111, and an angle of 90 degrees is formed between every two first pot support claws 150; a plurality of second pot support claws 160 may be provided, and the plurality of second pot support claws 160 may be arranged at intervals along the circumferential direction of the outer surface 111, and an angle of 90 degrees is formed between every two second pot support claws 160. The plurality of first pot support claws 150 and the plurality of second pot support claws 160 are arranged one by one.

[0069] See again Figure 1There may be a gap 170 between the outer plate surface 126 and the soup plate 140 for air circulation. This arrangement satisfies the need for secondary air replenishment without affecting the cooling of the soup plate 140. The second pot rack claw 160 may be plate-shaped, but other shapes are not excluded. There is a certain distance between the plurality of second pot rack claws 160, and the second pot rack claws 160 have a certain height, so that a gap 170 is formed between the outer plate surface 126 and the soup plate 140.

[0070] See again Figure 1 The gap 170 may have a height d in the installation direction of the pot support assembly 10, and the height d is 5 mm to 8 mm. For example, the height d may be 5 mm, 7 mm, 8 mm, etc. When the height d is 7 mm, the air replenishment effect is the best. Within this height range, the gap 170 satisfies the replenishment of secondary air and does not affect the cooling of the soup plate 140, avoiding the height being too high, resulting in excessive replenishment of secondary air, slow flow rate, affecting the cooling of the soup plate 140, and avoiding the height being too low, resulting in insufficient secondary air replenishment.

[0071] Combined with reference Figure 1 and Figure 4 , the second plate 120 may be provided with a vent hole 127, and the cavity 130 may be connected to the external space through the vent hole 127. Such a configuration can avoid the phenomenon that the gas in the cavity 130 is affected by thermal expansion and contraction, causing the first plate 110 or the second plate 120 to deform. Further, the vent hole 127 can be located on the arc portion of the second plate 120 facing the soup plate 140, so that the vent hole 127 can be hidden, making the pot support assembly 10 more beautiful. There can be multiple vent holes 127, and one vent hole 127 can be provided between every two second pot support claws 160. When there are four vent holes 127, the effect of avoiding the thermal expansion and contraction in the cavity 130 is the best.

[0072] Again, refer to Figure 1 and Figure 4 The vent hole 127 may have a diameter D1, and the diameter D1 may be 2 mm to 5 mm. For example, the diameter D1 may be 2 mm, 3 mm, 5 mm, etc. When the diameter D1 is 3 mm, the effect of preventing the cavity 130 from being affected by thermal expansion and contraction is best. Within this range, the vent hole 127 ensures that the gas in the cavity 130 is connected to the external gas, thereby effectively preventing the gas in the cavity 130 from being affected by thermal expansion and contraction, causing the first plate 110 or the second plate 120 to be deformed.

[0073] According to one aspect of the present invention, a burner is provided. Figure 1The burner may include an outer ring fire cover 20 and the pot support assembly 10 as described above, and the pot support assembly 10 may be arranged outside the outer ring fire cover 20. Since the pot support assembly 10 as described above has the above beneficial effects, the burner including the pot support assembly 10 as described above also has the above beneficial effects, which will not be described one by one here.

[0074] See again Figure 1 The pot support assembly 10 may include a pot support inner ring 180, and the outer ring fire cover 20 may include a fire hole outer ring 210. There may be a gap L1 between the pot support inner ring 180 and the fire hole outer ring 210, and the gap L1 may be 5 mm to 20 mm. For example, the gap L1 may be 5 mm, 10 mm, 20 mm, etc. When the gap between the pot support inner ring 180 and the fire hole outer ring 210 is within this range, the smoke emission is low and the thermal efficiency is high.

[0075] See again Figure 1 The inner ring 180 of the pot support has an inner ring top 181, the outer ring 210 of the fire hole has an outer ring top 211, and there is a distance d1 between the inner ring top 181 and the outer ring top 211, and d1 is 5mm to 15mm. For example, the distance d1 can be 5mm, 10mm, 15mm, etc. When the distance between the inner ring top 181 and the outer ring top 211 is within this range, the smoke emission is low and the thermal efficiency is high. As can be seen from Table 1, the thermal efficiency is the highest when the interval L1 is 15mm and the distance d1 is 10mm.
