The application provides an energy collecting disc, which is applied to a gas device provided with a burner 1000, wherein the gas device can be a gas stove, or an assembly of the gas stove and other electrical appliances, or other devices applied with the burner 1000, and the energy collecting disc is taken as an example for the following detailed description.

As shown in fig. 1, 2, 4, 5, 6 and 7, in some embodiments of the present application, the energy collecting disc includes a first disc 2000, a second disc 3000 and a partition 4000, the first disc 2000 encloses an inner cavity 2100, so that the first disc 2000 can be disposed around the burner 1000, the second disc 3000 is disposed around the first disc 2000, an outer cavity 3100 is formed between the second disc 3000 and the first disc 2000, the partition 4000 is disposed in the outer cavity 3100, and the partition 4000 partitions the outer cavity 3100, so that the outer cavity 3100 forms at least two partitioned cavities 3110, and at least a portion of high-temperature flue gas generated by the burner 1000 can enter the partitioned cavities 3110.

Through separating two at least separate chambers 3110 with outer chamber 3100, the high temperature flue gas that flows out from inner chamber 2100 can enter into different separate chambers 3110 for the high temperature flue gas realizes multistage stay at the in-process that flows out, so can avoid the heat that the high temperature flue gas carried to scatter and disappear too fast, thereby can more make full use of the heat of high temperature flue gas, improves the heat transfer effect between high temperature flue gas and the heated object 6000.

Specifically, the energy collecting tray is a structure that can collect heat to avoid excessive heat dissipation, and needs to be matched with the burner 1000 for use. The burner 1000 is a structure in which fuel gas is supplied to the burner and flows out to cause the fuel gas to be ignited to form flame, for example, the burner 1000 includes a burner and an ejector tube, the ejector tube is connected with the burner, the ejector tube is used for being matched with the air supply mechanism to eject the fuel gas toward the burner, and simultaneously, a certain amount of air is ejected to be mixed with the fuel gas to form a mixed gas to be conveyed into the burner, and the mixed gas flows out from the burner to be ignited by an ignition needle.

In general, the air supply mechanism comprises a nozzle, the nozzle receives the gas from the natural gas of the pipeline or the bottled liquefied gas, the nozzle corresponds to the air inlet of the injection pipe, the nozzle sprays the gas into the injection pipe, and meanwhile, the outside air is driven to enter the injection pipe through the air inlet of the injection pipe, so that the gas and the air are initially mixed in the injection pipe, the injection pipe injects and conveys the mixed gas to the furnace end, the furnace end has a larger space relative to the injection pipe, the gas and the air can be further uniformly mixed, and the full combustion of the gas is facilitated. The fire cover structure is generally arranged on the furnace head and is provided with a fire outlet hole, the fire outlet hole is communicated with the interior of the furnace head, and the mixed gas formed by the fuel gas and the air is sprayed out from the fire outlet hole and then is discharged by a nearby ignition needle to be ignited to form flame. It is to be understood that the structure of the burner 1000 is not limited to the foregoing examples.

When the combustor 1000 burns, high-temperature flue gas that the combustor 1000 produced can carry heat to distribute all around, in order to avoid the heat to follow the too fast loss of high-temperature flue gas, through setting up the energy collection dish, this energy collection dish surrounds the combustor 1000, so gather together the produced heat of combustor 1000, thereby avoid the too fast loss of heat, but with the continuous burning of combustor 1000, the heat still can follow the flow away of high-temperature flue gas and scatter and disappear, for this reason, in order to make more full use of heat, improve the energy efficiency, in this embodiment, optimize the structure through the energy collection dish and realize.

The first disc body 2000 of the energy collecting disc is disposed around the burner 1000, the first disc body 2000 is in an annular structure, in this embodiment, the annular shape may be a circular ring shape or a non-circular ring shape (for example, square ring shape), so that the first disc body 2000 encloses the inner cavity 2100, and after the burner 1000 and the first disc body 2000 are mounted on the gas stove, the first disc body 2000 is in a state of encircling the burner 1000. It should be noted that the first disc 2000 is located in the circumferential direction of the burner 1000, and the burner 1000 is located in the inner cavity 2100 when viewed along the axial direction of the burner 1000 (e.g., in the up-down direction), so that the first disc 2000 is referred to as surrounding the burner 1000. The direction of the gas stove is the front side of the gas stove facing the user, the back side of the gas stove facing away from the user, the left side corresponding to the left hand of the user, the right side corresponding to the right hand of the user, the lower side close to the ground and the upper side facing away from the ground.

The first disc 2000 surrounds the burner 1000, and the first disc 2000 can be designed to be higher relative to the burner 1000, so that a certain space can be defined between the first disc 2000 and the burner 1000, and the space is convenient for gathering high-temperature flue gas, so that a high-temperature region is formed.

When heating the object 6000, the object 6000 is placed on the gas stove and is located above the energy collecting plate, and the object 6000 needs to be arranged at intervals from the energy collecting plate and at a certain distance. Thus, along with the continuous combustion of the burner 1000, although the first tray 2000 can gather heat, along with the continuous generation of high-temperature flue gas, the high-temperature flue gas can flow upwards to meet the blocking of the heated object 6000, then change direction to emit around, finally flow out to the outside through between the heated object 6000 and the energy gathering tray, and the heat is also dissipated, so that the heat of the high-temperature flue gas flowing out of the inner cavity 2100 can be fully utilized, and the second tray 3000 and the partition 4000 are arranged.

The second tray 3000 surrounds the first tray 2000 and forms an outer cavity 3100 with the first tray 2000, and the heat insulation effect on the inner cavity 2100 is enhanced by the design of the outer cavity 3100. It will be appreciated that the first disc 2000 is designed to be relatively close to the burner 1000, so that the first disc 2000 needs to be designed to be resistant to high temperature, for example, may be made of a metal material, but the first disc 2000 is difficult to be insulated, so that the first disc 2000 itself is thermally conductive and then dissipates heat outwards, and by designing the second disc 3000 and forming the outer cavity 3100 with the first disc 2000, dissipation of heat from the inner cavity 2100 can be prevented to some extent.

Further, the outer cavity 3100 is open, and in the process of flowing the high-temperature flue gas, at least a part (for example, a part of the high-temperature flue gas) enters the outer cavity 3100, and another part of the high-temperature flue gas can directly flow out of the outside, so that the temperature of the outer cavity 3100 can be raised, the residence time of the high-temperature flue gas can be prolonged, and further, more sufficient heat exchange with the heated object 6000 can be achieved.

Further, the outer chamber 3100 (the partition chamber 3110) is opened toward the heated object 6000, so that the high-temperature flue gas generated by the burner 1000 flows upward to be redirected to diverge the flow when encountering the blockage of the heated object 6000, and since the outer chamber 3100 is opened toward the heated object, a part of the high-temperature flue gas is facilitated to enter the outer chamber 3100.

In addition, with respect to the inner cavity 2100 being a high temperature region, the outer cavity 3100 is a low temperature region, and the open end of the outer cavity 3100 (the open end of the separation cavity 3110, i.e. the opening) needs to be disposed at the outer side of the inner cavity 2100, so that the heat carried by the high-temperature flue gas flows to the open end of the outer cavity 3100 and then enters the outer cavity 3100 on the premise that the inner cavity 2100 and the heated object 6000 perform sufficient heat exchange, and the heat exchange with the heated object 6000 is continuously realized in the outer cavity 3100, so that the heat carried by the high-temperature flue gas can be fully utilized, and the energy efficiency is effectively improved.

Still further, a partition 4000 is provided in the outer chamber 3100, the partition 4000 dividing the outer chamber 3100 such that the outer chamber 3100 is divided by at least two divided chambers 3110 opened, for example, the number of the partition 4000 may be one, thus dividing the outer chamber 3100 by two divided chambers 3110, and the number of the partition 4000 may be two, thus dividing the outer chamber 3100 by three divided chambers 3110. In this embodiment, taking the partition 4000 as an example to partition the outer cavity 3100 into two partitioned cavities 3110, when the object 6000 to be heated is heated, the high-temperature flue gas generated by continuous combustion of the burner 1000 flows upward to meet the barrier of the object 6000 to be heated, then changes the direction to flow around, the high-temperature flue gas flows out from the space between the object 6000 to be heated and the first tray 2000, a part of flue gas enters one partitioned cavity 3110, a part of flue gas enters the other partitioned cavity 3110, and the rest of high-temperature flue gas is directly discharged to the outside, and through the arrangement of the two partitioned cavities 3110, the multi-stage barrier and residence of the high-temperature flue gas can be realized, the utilization of the heat carried by the high-temperature flue gas can be more effectively improved, and thus the energy efficiency can be improved.

As shown in connection with fig. 2, 4, and 7, in some embodiments of the present application, the partition 4000 is provided in a ring shape, and the partition 4000 needs to extend along the outer chamber 3100, so that the outer chamber 3100 is partitioned, such that the outer chamber 3100 is formed with at least two partitioned chambers 3110.

Specifically, as mentioned above, the burner 1000 continues to burn to generate flame, the flame is generated upward, so that the high temperature flue gas flows upward to meet the blockage of the heated object 6000, so that the high temperature flue gas flows toward the periphery, that is, in the direction surrounding the burner 1000, there is outflow of the high temperature flue gas, so in this embodiment, the partition 4000 is provided in a ring shape and extends along the outer chamber 3100, so that the partition chamber 3110 is also formed surrounding the burner 1000, a plurality (two or more) of the partition chambers 3110 are arranged in sequence in the radial direction of the first disk 2000, and the high temperature flue gas can enter into the partition chamber 3110 when flowing toward the periphery. In addition, at least two separating chambers 3110 are defined as a first separating chamber, a second separating chamber, a third separating chamber, and so on in the direction from inside to outside (i.e. the direction away from the burner 1000), for example, two separating chambers 3110 are taken as an example, the innermost separating chamber 3110 is the first separating chamber, and the second separating chamber is the outer side, when a part of the high-temperature flue gas enters the first separating chamber, under the effect that the burner 1000 continuously generates the high-temperature flue gas and the heat moves, fresh high-temperature flue gas continuously enters the first separating chamber, and the high-temperature flue gas in the first separating chamber can also flow out of the first separating chamber and enter the second separating chamber (of course, also fresh high-temperature flue gas enters the second separating chamber), so that the high-temperature flue gas can stay in the first separating chamber and the second separating chamber in sequence, and the heat of the high-temperature flue gas can be utilized more fully.

As shown in connection with fig. 4 and 6, in some embodiments of the present application, the second tray 3000, the separator 4000, and/or the first tray 2000 are designed to be detachably disposed, so that disassembly and cleaning are facilitated.

Specifically, the energy collecting disc is in a cooking environment and is easy to be polluted, after the gas stove is used for a period of time, the energy collecting disc is easy to be polluted, and the energy collecting disc is not easy to clean because the energy collecting disc surrounds the burner 1000, so that in the embodiment, the second disc 3000, the partition 4000 and/or the first disc 2000 are designed to be detachably arranged, the disassembly and the assembly are convenient, and a user can clean when needed.

For example, the second tray 3000, the partition 4000 and the first tray 2000 are designed to be detachable, i.e., the user can detach the second tray 3000, the partition 4000 and the first tray 2000, respectively, and then sequentially install them back to a predetermined position after cleaning is completed.

For another example, one of the second tray 3000, the partition 4000 and the first tray 2000 may be configured to be detachable, and the other two may be mounted to one of the above-mentioned two, so that the other two may be detached by detaching the one of the above-mentioned two.

Also for example, the partition 4000 is designed to be detachable, and after the partition 4000 is detached, the space (outer chamber 3100) between the second tray 3000 and the first tray 2000 will not be occupied, and cleaning is also easy at this time.

In some embodiments of the present application, the first tray 2000 and the partition 4000 are supported on the second tray 3000, so that the entire energy collecting tray can be easily assembled and disassembled. For example, when the energy collecting disc is installed, the second disc 3000 can be installed on the panel 7000, then the partition 4000 and the first disc 2000 are installed on the second disc 3000, and when the energy collecting disc needs to be detached, the detachment of the partition 4000 and the first disc 2000 can be completed only by detaching the second disc 3000, which is convenient and fast. Particularly, when the partition 4000 and the first tray 2000 are supported on the second tray 3000, corresponding positioning and mounting structures can be designed on the second tray 3000 to better match the mounting of the partition 4000 and the first tray 2000, without setting positioning and mounting structures on the panel 7000 for the partition 4000 and the first tray 2000.

As shown in fig. 6 and 7, in some embodiments of the present application, the partition 4000 and the first tray 2000 are designed as an integrally formed structure, so that the number of parts can be reduced.

Specifically, the integrated molding of the partition 4000 and the first disc 2000 may be that the partition 4000 and the first disc 2000 may be formed by casting with a mold, or the partition 4000 and the first disc 2000 may be manufactured by a plate and based on punching, bending, stamping, or the like, so that the partition 4000 and the first disc 2000 may be integrated into one piece, thereby reducing the amount of materials.

It will be appreciated that when the partition 4000 and the first tray 2000 are integrally formed, the partition cavity 3110 is formed between the partition 4000 and the first tray 2000, and when the partition 4000 is combined with the second tray 3000, the second tray 3000 needs to surround the partition 4000, so that the remaining partition cavity 3110 is formed.

As shown in fig. 3 and 8, in some embodiments of the present application, the first disc 2000 is provided with at least two outer cavities 2220 along the direction of the first disc 2000 being gradually expanded, and the side of the first disc 2000 facing the outer cavity 3100 is provided with at least two outer cavities 2220, so that the residence time of the high-temperature flue gas in the outer cavity 3100 can be further prolonged.

Specifically, the first disc 2000 is designed to be gradually expanded toward the upper side, that is, the first disc 2000 is gradually expanded from bottom to top, so as to form a horn-like structure similar to the structure that is opened toward the upper side, an outer cavity 2220 is provided on one side of the first disc 2000 toward the outer cavity 3100 (the partition cavity 3110 adjacent to the first disc 2000), the outer cavity 2220 is concavely provided away from the outer cavity 3100, and at least two outer cavities 2220 are provided along the gradually expanding direction of the first disc 2000. It will be appreciated that a so-called outer cavity 2220, i.e., a position on the side of the first disk 2000 facing the outer cavity 3100, is recessed with respect to the surroundings of the position, thus constituting the outer cavity 2220.

When the object 6000 to be heated is heated, heat is transferred to the outer cavity 3100 through the first tray 2000, so that gas in the outer cavity 3100 is active and flows, meanwhile, high-temperature flue gas generated by combustion of the burner 1000 flows upwards and then meets the blocking of the object 6000 to be heated, the high-temperature flue gas changes direction and flows out from between the object 6000 to be heated and the first tray 2000, a part of the high-temperature flue gas enters into a separation cavity 3110 formed between the separation piece 4000 and the first tray 2000 and flows, the flue gas flows along one side of the first tray 2000 facing the outer cavity 3100, and due to the at least two outer cavities 2220, vortex flow is generated when the high-temperature flue gas flows through the outer cavities 2220, the speed of the high-temperature flue gas can be delayed, and the high-temperature flue gas can be enabled to flow, so that heat exchange between the high-temperature flue gas and the object 6000 to be heated is improved, and the too fast dissipation of heat is further avoided.

It will be appreciated that the outer cavities 2220 may be two, three, four or more, as mentioned above, and the high temperature flue gas may flow along the first disc 2000 toward one side of the outer cavity 3100, when a plurality of (two or more) outer cavities 2220 are arranged along the diverging direction of the first disc 2000, meaning that a plurality of outer cavities 2220 are arranged from bottom to top, the high temperature flue gas may sequentially flow through each of the outer cavities 2220, and even if one of the outer cavities 2220 does not form a vortex to the high temperature flue gas, the rest of the outer cavities 2220 may form a vortex to the flue gas, thereby improving the residence time of the high temperature flue gas in the current separating cavity 3110.

In some embodiments of the present application, as shown in fig. 12, the first disc 2000 is disposed in a diverging manner, and along the diverging direction of the first disc 2000, at least two inner cavities 2210 are disposed on the side of the first disc 2000 facing the inner cavity 2100, so as to further extend the residence time of the high-temperature flue gas in the inner cavity 2100.

Specifically, the first disc 2000 is designed to be gradually expanded toward the upper side, that is, the first disc 2000 is gradually expanded from bottom to top, and a horn-shaped structure similar to that of opening toward the upper side is formed, an inner cavity 2210 is disposed on one side of the first disc 2000 toward the inner cavity 2100, the inner cavity 2210 is concavely disposed back to the inner cavity 2100, and at least two inner cavities 2210 are disposed along the gradually expanding direction of the first disc 2000. It will be appreciated that a so-called inner cavity 2210, i.e. a position of the side of the first disc 2000 facing the inner cavity 2100, is recessed with respect to the surroundings of this position, thus constituting the inner cavity 2210.

When heating the object 6000 to be heated, the high-temperature flue gas generated by the combustion of the burner 1000 flows upwards to meet the blocking of the object 6000 to be heated, and then changes the direction to flow towards the periphery, in the process, the flue gas flows towards one side of the inner cavity 2100 along the first disc 2000 due to the fact that the flue gas flows towards the periphery, the high-temperature flue gas sequentially flows through the inner cavity 2210 and is just the effect of the inner cavity 2210, so that vortex is generated on one side of the first disc 2000 towards the inner cavity 2100, the flue gas stays in the inner cavity 2100 for a longer time due to the formation of vortex, and the excessive rapid dissipation of heat can be further avoided.

The inner cavities 2210 may be one, two, three, four or more, as mentioned above, the high temperature smoke may flow along the first tray 2000 toward one side of the inner cavity 2100, when a plurality of (two or more) inner cavities 2210 are arranged along the diverging direction of the first tray 2000, meaning that a plurality of inner cavities 2210 are arranged from bottom to top, the high temperature smoke may sequentially flow through each inner cavity 2210, even though the lowermost inner cavity 2210 does not form a vortex to the high temperature smoke, the high temperature smoke may form a vortex to the smoke through the upper inner cavity 2210, thereby increasing the residence time of the high temperature smoke in the inner cavity 2100.

As shown in connection with fig. 3 and 8, in some embodiments of the present application, the inner cavity 2210 is designed to protrude toward the outer cavity 3100, and the outer cavity 2220 is designed to protrude toward the inner cavity 2100, and the inner cavity 2210 and the outer cavity 2220 are designed to be alternately arranged along the diverging direction of the first disc 2000.

Specifically, when the inner cavity 2210 is concavely disposed opposite to the inner cavity 2100 and synchronously protrudes toward the outer cavity 3100, the outer cavity 2220 is concavely disposed opposite to the outer cavity 3100 and synchronously protrudes toward the inner cavity 2100, so that the inner cavity 2210 and the outer cavity 2220 are alternately disposed in sequence along the diverging direction of the first disc 2000, so that the inner cavity 2210 and the outer cavity 2220 form a continuous undulating structure, similar to a stepped structure, an outer cavity 2220 can be formed between two adjacent inner cavities 2210, an inner cavity 2210 can be formed between two adjacent outer cavities 2220, so that the inner cavity 2210 and the outer cavity 2220 can be designed to be closer to each other, and the high-temperature flue gas flows along one side of the first disc 2000 toward the inner cavity 2100 and one side toward the outer cavity 3100 more easily to form continuous vortices, thereby enhancing the retention effect of the high-temperature flue gas.

In addition, by protruding the outer cavity 2220 toward the inner cavity 2100 and protruding the inner cavity 2210 toward the outer cavity 3100, the manufacturing difficulty of the inner cavity 2210 and the outer cavity 2220 can be reduced, and the cost of the first disc 2000 can be reduced. For example, the first tray 2000 is manufactured by using a metal plate, and the metal plate is clamped by two dies, so that the metal plate forms the inner cavity 2210 and the outer cavity 2220 due to the certain ductility of the metal plate, thereby improving the production efficiency.

As shown in conjunction with fig. 2, 8, 9 and 10, in some embodiments of the present application, the top of the first tray 2000 is spaced apart from the heated object 6000, and a side of the top of the first tray 2000 facing the heated object 6000 is defined as a guide side 2300, and the guide side 2300 is designed to be parallel to the heated object 6000.

Specifically, by arranging the flow guiding side 2300, the flow guiding side 2300 and the heated object 6000 are designed to be parallel to each other, so that when high-temperature flue gas flows between the flow guiding side 2300 and the heated object 6000, laminar flow is formed, and the flow of the high-temperature flue gas is accelerated by the laminar flow, so that the scouring of the heated object 6000 is enhanced, the convection heat exchange coefficient is improved, more efficient heat transfer is realized, and the heat exchange effect is further improved. It will be appreciated that the so-called parallel flow guide sides 2300 form flow channels between the corresponding portions of the heated object 6000, the flow area of which is relatively constant in the direction of flow of the high-temperature flue gas, thereby forming a laminar flow.

For example, the top of the first tray 2000 forms a flow guiding side 2300, the flow guiding side 2300 is horizontally disposed, the flow guiding side 2300 corresponds to the bottom of the object 6000 to be heated, and is spaced from the bottom of the object 6000 to be heated, when the object 6000 to be heated is a pot, the flow guiding side 2300 corresponds to the bottom of the pot, a flow channel is formed between the flow guiding side 2300 and the bottom of the pot, and when the flue gas is discharged through the space between the flow guiding side 2300 and the bottom of the pot, a laminar flow is formed, and the scouring of the bottom of the pot is enhanced, thereby improving the convective heat transfer coefficient.

In order to ensure that an effective laminar flow is formed between the guide side 2300 and the heated object 6000, as shown in connection with fig. 2, in some embodiments of the application, the energy collecting tray further comprises legs 5000, the heated object 6000 is arranged to rest on the legs 5000 so as to be spaced apart from the guide side 2300, and the distance between the guide side 2300 and the highest point of the legs 5000 is H, which satisfies 2 mm.ltoreq.h.ltoreq.10mm, especially when H satisfies 4 mm.ltoreq.h.ltoreq.6mm, has a better laminar flow effect, which satisfies the use of different heated objects 6000.

It will be appreciated that the supporting legs 5000 may be disposed on the first tray 2000, the partition 4000, or the second tray 3000, however, it is also possible that the supporting legs 5000 fix at least two of the first tray 2000, the partition 4000 and the second tray 3000, and may be disposed according to practical situations.

As shown in connection with fig. 9, 10 and 11, in some embodiments of the present application, the top of the first tray 2000 is spaced apart from the heated object 6000, and a side of the top of the first tray 2000 facing the heated object 6000 is defined as a guide side 2300, and the guide side 2300 is designed as a non-planar structure. In this embodiment, the flow guiding side 2300 and the heated object 6000 are arranged alternately, and the high-temperature flue gas generated by the burner 1000 can flow out from between the flow guiding side 2300 and the heated object 6000, so that the high-temperature flue gas can receive larger along-path resistance when flowing through the flow guiding side 2300 by designing the flow guiding side 2300 to reduce the speed of the high-temperature flue gas flowing through the flow guiding side 2300 and the heated object 6000 (relatively speaking, the flow guiding side 2100 is a plane), when the flow of the high-temperature flue gas is slower, the high-temperature flue gas can have longer time to contact with the heated object 6000, thus prolonging the contact time between the high-temperature flue gas and the heated object 6000, improving the heat exchange effect between the high-temperature flue gas and the heated object 6000 and further improving the energy efficiency.

The non-planar structure has various forms, and as shown in connection with fig. 9 and 10, in some embodiments of the present application, the flow guiding side 2300 is designed as a concave-convex structure, that is, a structure having a concave portion (hereinafter, first concave portion 2310) and a convex portion (hereinafter, first convex portion 2320), and the concave-convex structure is formed by cooperation of the concave portion (first concave portion 2310) and the convex portion (first convex portion 2320). In the process of flowing through the diversion side 2300, the high-temperature flue gas can be subjected to the resistance applied by the concave part (the first concave part 2310) and the resistance applied by the convex part (the first convex part 2320), and the flow speed of the high-temperature flue gas is further delayed through the arrangement of the concave-convex structure.

As shown in connection with fig. 9 and 10, in some embodiments of the present application, the first concave portions 2310 and the first convex portions 2320 are designed to be alternately arranged along the radial direction of the first disk 2000, so that the first concave portions 2310 and the first convex portions 2320 form a wave shape, and the flow resistance of the high-temperature flue gas is further improved, so that the heat exchange effect between the high-temperature flue gas and the heated object 6000 is further enhanced.

Specifically, if the first concave portion 2310 and the first convex portion 2320 are to be alternately arranged, at least two first concave portions 2310 and/or at least two first convex portions 2320 need to be provided.

In this example, two first protrusions 2320 are provided and one first recess 2310 is provided, where one first protrusion 2320 is closer to the center of the first disk 2000 than the other first protrusion 2320 and first recess 2310, and the first recess 2310 is located between the two first protrusions 2320. By the alternating arrangement of the first convex portions 2320 and the first concave portions 2310, the flow guiding side 2300 forms a continuous undulating structure (wavy) in the radial direction of the first disk 2000, and a better blocking effect is formed on the high-temperature flue gas flowing through the flow guiding side 2300, so that the high-temperature flue gas flows through the flow guiding side 2300 more slowly.

As shown in connection with fig. 11, in some embodiments of the present application, the flow guiding side 2300 has a plurality of flow guiding ribs 2410, the plurality of flow guiding ribs 2410 are arranged at intervals along the circumferential direction of the first disk 2000, such that flow guiding channels 2420 are formed between adjacent flow guiding ribs 2410, and the extending direction of the flow guiding channels 2420 is designed to deviate from the radial direction of the first disk 2000, i.e., to deviate from the radial direction of the first disk 2000. Through setting up water conservancy diversion muscle 2410 to the skew form water conservancy diversion passageway 2420 that adjacent water conservancy diversion muscle 2410 formed, so can prolong the flow path of high temperature flue gas, make the contact heat transfer of longer time between high temperature flue gas and the heated object 6000, so also can improve the heat transfer effect, promote the energy efficiency.

Specifically, when the high-temperature flue gas floats upwards and encounters the blockage of the heated object 6000, the high-temperature flue gas flows towards the periphery, and the flow towards the periphery is approximately along the radial direction of the first disc 2000, in this embodiment, by providing the flow guiding ribs 2410, the flow guiding channel 2420 formed by the adjacent flow guiding ribs 2410 is inclined relative to the radial direction of the first disc 2000, so when the high-temperature flue gas flows to the flow guiding channel 2420, the high-temperature flue gas also flows obliquely relative to the radial direction of the first disc 2000 along the extending direction of the flow guiding channel 2420, so when the high-temperature flue gas flows to the flow guiding channel 2420, the high-temperature flue gas can not flow along the radial direction of the first disc 2000 any more, but flows continuously along the extending direction of the flow guiding channel 2420, which is equivalent to prolonging the flow path of the high-temperature flue gas, and the flow path of the high-temperature flue gas is longer, which means that the high-temperature flue gas can realize more sufficient contact with the heated object 6000, thus being beneficial to improving the heat exchange effect. It can be appreciated that the arrangement of the diversion ribs 2410 at intervals is also equivalent to forming a concave-convex structure on the diversion side 2300, and the heat exchange effect between the high-temperature flue gas and the heated object 6000 can be greatly improved by matching with the deflection arrangement of the diversion channels 2420.

It is to be understood that the top of the partition 4000 may also form the flow guiding side 4100, similar to the flow guiding side 4100 of the first tray 2000, the flow guiding side 4100 of the partition 4000 may also be designed to be parallel to the heated object 6000 or be designed to be in a non-planar structure, and specific technical effects refer to the flow guiding side 4100 of the first tray 2000 and will not be repeated herein.

The application also discloses a gas stove, and the gas stove comprises the energy collecting disc of the embodiment, as shown in fig. 1 and 5, it can be appreciated that the energy collecting disc of the gas stove adopts the technical scheme of the embodiment, so that the gas stove at least has the beneficial effects brought by the technical scheme of the embodiment and is not repeated here.
