[0026] The waste heat recovery cooker provided in the embodiments of the present application has made multiple improvements to the heat dissipation performance of the cold end of the temperature difference power generation module, including:

[0027] The cold end of the temperature difference power generation module is arranged on the lower surface, so that the distance between the cold end and the burner is farther in the longitudinal direction, which is conducive to ensuring effective heat dissipation of the cold end and expanding the temperature difference between the cold end and the hot end;

[0028] The radiator is arranged below the cold end of the thermoelectric power generation module, and the cold end of the thermoelectric power generation module and the radiator are arranged away from the burner in sequence, so as to ensure that the cold end of the thermoelectric power generation module can be reliably cooled by the radiator located below the cold end;

[0064] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art fall within the scope defined by the claims attached to this application.

[0065] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0066] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0067] The applicant found that the greater the temperature difference between the hot and cold ends of the temperature difference power generation chip, the more conducive it is to the increase in power generation. However, in gas stoves that currently use temperature difference power generation chips to absorb waste heat for power generation and store it in batteries, the hot and cold ends of the temperature difference power generation chip cannot form a large temperature difference, and the power generation efficiency is low. The power generation still cannot meet the large power consumption needs of gas stoves in multiple scenarios such as ignition, linkage, and security.

[0068] The utility model provides a waste heat recovery cooker, which can effectively improve the heat dissipation performance of the cold end of the temperature difference power generation module and ensure a large temperature difference between the hot end and the cold end.

[0069] Please refer to Figures 1 to 10 In the embodiment of the present application specification, a waste heat recovery stove is provided, which may include: a burner; a rechargeable battery module 2, the battery module 2 is used to supply the power required for the waste heat recovery stove to work; a temperature difference power generation module 3, the temperature difference power generation module 3 is directly or indirectly electrically connected to the battery module 2, the temperature difference power generation module 3 has a cold end and a hot end; the temperature difference power generation module 3 has an upper surface and a lower surface, the upper surface includes the hot end, and the lower surface includes the cold end; a heat collector, the heat collector is arranged close to the burner, the heat collector is directly or indirectly connected to the hot end of the temperature difference power generation module 3, and is used to collect the waste heat of the burner; a radiator 7, the radiator 7 is electrically connected to the temperature difference power generation module The cold end of the module 3 is directly or indirectly in contact, and the radiator 7 is located below the cold end of the thermoelectric power generation module 3; the shell 10, the shell 10 includes: a bottom shell 14 and a panel 13 arranged on the bottom shell 14, the thermoelectric power generation module 3 is arranged between the bottom surface 141 of the bottom shell 14 and the panel 13, the bottom surface 141 is provided with a mounting hole 1411 for at least part of the radiator 7 to pass through, at least part of the radiator 7 protrudes downward from the bottom surface 141 through the mounting hole 1411; a circulation portion for air flow is formed between the radiator 7 and the mounting hole 1411, when the burner is working, external air can flow through the radiator 7 and flow to the burner through the circulation portion.

[0070] In the embodiment of the present application, the stove may include: a shell 10, a burner, a battery module 2, a temperature difference power generation module 3, a heat collector and a radiator 7, etc.

[0071] Among them, the burner may include a left burner 11 located on the left side of the waste heat recovery stove and a right burner 12 located on the right side of the waste heat recovery stove. When the burner includes the left burner 11 and the right burner 12, the waste heat recovery stove is a double-burner stove. In the embodiments and drawings of the present application, the double-burner stove is mainly used as an example for explanation. Of course, in some other scenarios, when the waste heat recovery stove has more or fewer burners, adaptive adjustments can be made with reference to the present application, and the present application will not be described one by one here.

[0072] In this embodiment, the battery module 2 is a rechargeable battery module, which is used to supply the power required for the operation of the waste heat recovery stove. When the waste heat recovery stove is working, the temperature difference power generation module 3 is used to convert part of the heat generated by the left burner 11 and / or the right burner 12 into electrical energy and supply it to the battery module 2.

[0073] Please refer to Figure 2 and Figure 4 , the shell 10 can be a hollow structure as a whole. Specifically, the shell 10 can include: a bottom shell 14 and a panel 13 arranged on the bottom shell 14. The panel 13 can be installed on the bottom shell 14 in a detachable manner. Specifically, the panel 13 can be a rectangular panel 13 with a certain thickness as a whole. The panel 13 can be provided with a left opening for positioning the left burner 11 and a right opening for positioning the right burner 12. The bottom shell 14 can be used to install components such as the battery module 2 and the thermoelectric power generation module 3. The bottom shell 14 can be a cavity structure with an upper end opening as a whole, and the bottom shell 14 can include a bottom surface 141 and a side surface 142 surrounded by the bottom surface 141. Among them, the circumferential contour of the side surface 142 parallel to the panel 13 can be rectangular or quasi-rectangular, so as to facilitate adaptation and installation with the installation hole reserved in the user's kitchen.

[0074] like Figure 3 As shown, the housing 10 is arranged along the left and right directions (i.e. Figure 3 In the first direction X) shown in FIG, a left burner 11 and a right burner 12 are arranged at intervals. Specifically, the left burner 11 is positioned at the left side of the cooker through the left opening, and the right burner 12 is positioned at the right side of the cooker through the right opening.

[0075] The structures of the left burner 11 and the right burner 12 can be the same or similar. In the embodiment of the present application, one of the burners, for example Fig. 9The left burner 11 shown is taken as an example for key explanation. The structure of the right burner 12 can refer to the left burner 11, and the present application will not repeat it here. The left burner 11 may include an inner fire cover and an outer fire cover, and the left burner 11 also has an inner gas outlet and an outer gas outlet. The inner fire cover is mounted on the inner gas outlet, and the inner gas outlet is connected to the inner gas ejector pipe, and the gas flowing in from the inner gas ejector pipe can flow out through the inner gas outlet and then be ejected from the hole opened on the inner fire cover. The outer fire cover is mounted on the outer gas outlet, and the outer gas outlet is connected to the outer ring gas ejector pipe, and the gas flowing in from the outer gas ejector pipe can flow out through the outer gas outlet and then be ejected from the hole opened on the outer fire cover.

[0076] like Figure 3 As shown, the temperature difference power generation module 3 can be arranged between the left burner 11 and the right burner 12 and located in the middle of the stove. Specifically, the composition and form of the temperature difference power generation module 3 are not limited in this application. For example, the temperature difference power generation module 3 can include only one temperature difference power generation unit, or can include multiple temperature difference power generation units. When the temperature difference power generation module 3 includes multiple temperature difference power generation units, it can include two or more temperature difference power generation units, and multiple temperature difference power generation units can be connected in series and / or in parallel. Among them, the temperature difference power generation module 3 as a whole can be a rectangular structure with a certain thickness. Of course, the structure of the temperature difference power generation module 3 can also be other structures, and this application does not make specific limitations here.

[0077] The temperature difference power generation module 3 has a cold end and a hot end. The inventor of the present application has found that after the heat generated by the current burner is transferred to the hot end, the temperature of the hot end can basically rise to the limit temperature, and it is difficult to further increase the temperature of the hot end, or in other words, the increase is relatively limited, and the effect of expanding the temperature difference between the hot end and the cold end is not significant. On this basis, in order to expand the temperature difference between the hot end and the cold end, one of the key improvements of the present application is to improve the heat dissipation performance of the cold end and effectively control the temperature of the cold end.

[0078] In the thickness direction, the hot end can be arranged on the upper surface of the thermoelectric power generation module 3, and the cold end can be arranged on the lower surface of the thermoelectric power generation module 3, so that in the longitudinal direction, the distance between the cold end and the left burner 11 and the right burner 12 is farther, which is more conducive to ensuring effective heat dissipation of the cold end to expand the temperature difference between the cold end and the hot end. In addition, relative to the cold end located on the lower surface, the hot end located on the upper surface can be in contact with a component with a higher temperature (such as the panel 13 of the shell 10) for heat transfer, which is conducive to increasing the temperature of the hot end, and further expanding the temperature difference between the hot end and the cold end, ensuring that the thermoelectric power generation module 3 can generate sufficient power. For this cooker, the left burner 11 and the right burner 12 can be a left-right symmetrical structure in the first direction X.

[0079] The temperature difference power generation module 3 can be located between the two burners and in the middle of the stove, which can ensure that the cold end of the temperature difference power generation module 3 is relatively far from the left burner 11 or the right burner 12, so that the temperature of the cold end of the temperature difference power generation module 3 will not be affected by the burner and become too high, which is conducive to ensuring that the cold end and the hot end of the temperature difference power generation module 3 achieve a large temperature difference and generate sufficient power. In addition, when the temperature difference power generation module 3 is set in the middle of the stove, the space in the middle area of ​​the stove can be fully utilized without changing the plug valve, pipeline, etc. inside the stove, and without increasing the size of the shell 10, the processing and manufacturing cost is low and the production and processing difficulty is low.

[0080] Specifically, the ratio of the distance from the center of the thermoelectric power generation module 3 to the center of the left burner 11 to the distance from the center of the thermoelectric power generation module 3 to the center of the right burner 12 is in the range of 0.8-1.2. The center distance of the thermoelectric power generation module 3 to the center of the left burner 11 is L1, and the center distance of the thermoelectric power generation module 3 to the center of the right burner 12 is L2. The ratio of L1 to L2 can be between 0.8 and 1.2, thereby ensuring that the cold end of the thermoelectric power generation module 3 is not affected by the burner and the temperature is too high.

[0081] Furthermore, the distance from the center of the temperature difference power generation module 3 to the center of the left burner 11 is equal to the distance from the center of the temperature difference power generation module 3 to the center of the right burner 12 .

[0082] In this embodiment, the center of the temperature difference power generation module 3 can be located on the median perpendicular line EE of the line connecting the center of the left burner 11 and the center of the right burner 12. When the center of the temperature difference power generation module 3 is on the median perpendicular line EE, its distance from the center of the left burner 11 is equal to the distance from the right burner 12, thereby ensuring that the cold end of the temperature difference power generation module 3 is spaced a large distance from the left burner 11 and the right burner 12. Regardless of whether the left burner 11 is working, the right burner 12 is working, or the left burner 11 and the right burner 12 are working at the same time, the cold end temperature of the temperature difference power generation module 3 can be effectively controlled and the temperature will not rise too much.

[0083] The heat collector is arranged near the burner, and the heat collector is directly or indirectly connected to the hot end of the thermoelectric power generation module, and is used to collect the waste heat of the burner. When the burner includes a left burner 11 located at the left side of the waste heat recovery stove and a right burner 12 located at the right side of the waste heat recovery stove, the heat collector may include: a left heat collector 41 arranged near the left burner 11 and a right heat collector 42 arranged near the right burner 12. Among them, the left heat collector 41 may include a left heat collecting member arranged near the left burner 11 and a left heat transfer member for connecting the hot end of the thermoelectric power generation module 3 with the left heat collecting member. The right heat collector 42 may include a right heat collecting member arranged near the right burner 12 and a right heat transfer member for connecting the hot end of the thermoelectric power generation module 3 with the right heat collecting member.

[0084] Please refer to Figure 7 and Figure 8 In this embodiment, the radiator 7 is mainly used to dissipate heat and cool down the cold end of the temperature difference power generation module 3.

[0085] Among them, the cold end of the thermoelectric power generation module 3 can be directly or indirectly attached to the radiator 7, so as to expand the heat exchange area between the cold end and the radiator 7. Specifically, the radiator 7 includes a substrate 71 and heat dissipation fins 72 arranged on the substrate 71. The shape and structure of the substrate 71 can be adapted to the shape and structure of the cold end of the thermoelectric power generation module 3. For example, when the thermoelectric power generation module 3 as a whole is a rectangular structure with a certain thickness, the substrate 71 can be a rectangular plate with a certain thickness. A plurality of heat dissipation fins 72 can be provided on the lower surface of the substrate 71, and the heat dissipation fins 72 can be evenly spaced at a certain distance. The heat dissipation fins 72 can specifically be aluminum fins with better heat dissipation performance. Among them, the specific structure, layout method, material, etc. of the heat dissipation fins 72 are not specifically limited in this application.

[0086] The upper surface of the substrate 71 can be in direct or indirect contact with the cold end, thereby ensuring that there is a large heat exchange area between the substrate 71 and the cold end of the thermoelectric power generation module 3, thereby achieving an ideal heat dissipation effect.

[0087] For example, when the cold end of the temperature difference power generation module 3 is directly attached to the substrate 71 of the radiator 7, without considering the manufacturing and installation errors, the cold end and the substrate 71 of the radiator 7 can be attached surface to surface, thereby ensuring that the cold end and the substrate 71 have a maximum contact area.

[0088] Alternatively, when the cold end of the thermoelectric power generation module 3 is indirectly attached to the substrate 71 of the radiator 7, a heat-conducting medium is arranged between the cold end of the thermoelectric power generation module 3 and the substrate 71 of the radiator 7, and the cold end of the thermoelectric power generation module 3 and the substrate 71 of the radiator 7 are indirectly attached to each other through the heat-conducting medium, thereby ensuring that the cold end of the thermoelectric power generation module 3 and the substrate 71 of the radiator 7 have a maximum heat exchange area and better thermal conductivity, thereby enabling the cold end of the thermoelectric power generation module 3 to be effectively cooled and cooled.

[0089] Specifically, the heat conducting medium may be thermal grease, which is a highly thermally conductive insulating silicone material that almost never solidifies and can maintain a grease state for a long time at a temperature of -50°C to +230°C. It has both excellent electrical insulation and excellent thermal conductivity.

[0090] When the thermal grease is filled between the cold end of the temperature difference power generation module 3 and the substrate 71 of the radiator 7, it can ensure that the cold end of the temperature difference power generation module 3 and the substrate 71 of the radiator 7 are fitted with zero gap, and the radiator 7 is assisted to achieve better heat conduction and heat dissipation of the cold end of the temperature difference power generation module 3. Of course, the thermal conductive medium can also be other materials, and the specific material of the thermal conductive medium is not specifically limited in this application.

[0091] In one embodiment, the area of ​​the substrate 71 is greater than or equal to the area of ​​the cold end of the thermoelectric power generation module 3. When the area of ​​the substrate 71 is greater than or equal to the area of ​​the cold end of the thermoelectric power generation module 3, the substrate 71 of the heat sink 7 can cover the entire cold end of the thermoelectric power generation module 3, thereby efficiently conducting heat and dissipating heat from the cold end of the thermoelectric power generation module 3.

[0092] Furthermore, in order to ensure better thermal conductivity and heat dissipation performance between the cold end of the thermoelectric power generation module 3 and the substrate 71 of the radiator 7, a heat conducting medium may be filled in the gap between the cold end of the thermoelectric power generation module 3 and the substrate 71 of the radiator 7.

[0093] Please refer to Figures 7 and 8 In this embodiment, the thermoelectric power generation module 3 has an upper surface and a lower surface, the upper surface includes the hot end, the lower surface includes the cold end, and the radiator 7 is located below the cold end of the thermoelectric power generation module 3.

[0094] When the radiator 7 is located below the cold end of the thermoelectric power generation module 3, the cold end of the thermoelectric power generation module 3 and the radiator 7 are respectively arranged away from the heat source (the left burner 11 and the right burner 12), which is beneficial to ensure that the cold end of the thermoelectric power generation module 3 can be reliably dissipated and cooled by the radiator 7 located below the cold end.

[0095] The position of the radiator 7 can match the position of the temperature difference power generation module 3. Specifically, when the temperature difference power generation module 3 is arranged between the left burner 11 and the right burner 12 and located in the middle of the cooker, the radiator 7 can be located in the middle of the cooker and the radiator 7 is in direct or indirect contact with the cold end of the temperature difference power generation module 3. The contact method can be different according to the different matching relationship between the cold end of the temperature difference power generation module 3 and the radiator 7, and is not specifically limited here.

[0096] Please refer to Figure 4 and Fig. 9 The shell 10 includes a bottom shell 14 and a panel 13 arranged on the bottom shell 14, the temperature difference power generation module 3 is arranged between the bottom shell 14 and the panel 13, and a mounting hole 1411 for partially passing the radiator 7 is opened in the middle of the bottom shell 14, and at least part of the radiator 7 protrudes downward from the bottom shell 14 through the mounting hole 1411.

[0097] In this embodiment, the bottom shell 14 of the cooker may include a bottom surface 141 and a side surface 142 surrounding the bottom surface 141. A mounting hole 1411 may be provided in the middle of the bottom surface 141, and the radiator 7 may be inserted into the mounting hole 1411. At least part of the radiator 7 protrudes from the outer surface of the bottom surface 141 through the mounting hole 1411. In this way, the radiator 7 can connect the external air with the inside of the shell 10 of the cooker, and the external air can directly contact the radiator 7, so as to take away the heat on the radiator 7, that is, to dissipate the heat of the radiator 7, reliably control the temperature rise of the radiator 7, and further ensure that the radiator 7 reliably dissipates the heat and cools down the cold end of the thermoelectric power generation module 3.

[0098] Furthermore, a flow portion for air flow is formed between the heat sink 7 and the mounting hole 1411. When the burner is working, external air can flow through the heat sink 7 and flow to the burner through the flow portion.

[0099] In this embodiment, a flow portion may be formed between the heat sink 7 and the mounting hole 1411. For example, a gap is formed between at least one side wall of the heat sink 7 and the mounting hole 1411 to form a flow portion, or the heat dissipation fins 72 of the heat sink 7 are partially located inside the housing 10 and partially located outside the housing 10 along the depth direction (a direction perpendicular to the first direction X and the second direction Y). The flow portion is formed by the gaps between adjacent heat dissipation fins 72, and the outside of the housing 10 and the inside of the housing 10 can also be connected. By using the flow portion, the external air can flow through the heat sink 7 through the flow portion, thereby dissipating the heat of the heat sink 7, reliably controlling the temperature rise of the heat sink 7, and then ensuring that the heat sink 7 reliably dissipates heat and cools the cold end of the thermoelectric power generation module 3.

[0100] Please refer to Figures 5 and 6 When the cooker is working, it is necessary to introduce air from outside the housing 10 as primary air to the left burner 11 and / or the right burner 12 to provide the combustion-supporting oxygen required for combustion. Specifically, when the gas at the left burner 11 and / or the right burner 12 passes through the nozzle, it will draw the surrounding air to form primary air. In the process of forming the primary air, it will drive the normal temperature air outside the housing 10 to flow into the burner at a faster speed.

[0101] In the embodiment of the present application, the flow path of the normal temperature air can be cleverly controlled during the process of introducing external normal temperature air into the left burner 11 and / or the right burner 12, so that the introduced normal temperature air with a faster flow rate first flows through the radiator 7 before flowing into the left burner 11 and / or the right burner 12 to dissipate the heat of the radiator 7, thereby improving the heat dissipation effect of the radiator 7 itself and further improving the heat dissipation and cooling effect of the radiator 7 on the cold end of the temperature difference power generation module 3.

[0102] On the whole, the waste heat recovery cooker provided in the embodiment of the present application has made multiple improvements to the heat dissipation performance of the cold end of the temperature difference power generation module, including: the cold end of the temperature difference power generation module is arranged on the lower surface, so that in the longitudinal direction, the distance between the cold end and the burner is farther, which is conducive to ensuring effective heat dissipation of the cold end to expand the temperature difference between the cold end and the hot end; the radiator is arranged below the cold end of the temperature difference power generation module, and the cold end of the temperature difference power generation module 3 and the radiator 7 are arranged away from the burner in turn, which is conducive to ensuring that the cold end of the temperature difference power generation module 3 can be reliably dissipated and cooled by the radiator 7 located below the cold end; a mounting hole for penetrating the radiator is provided on the bottom surface, and at least part of the radiator protrudes from the bottom surface 1 through the mounting hole 1411. 41, so that the radiator 7 can connect the external air with the interior of the shell 10 of the stove, and the external air can directly contact the radiator 7, so as to take away the heat on the radiator 7, that is, to dissipate the heat of the radiator 7, reliably control the temperature rise of the radiator 7, and then ensure that the radiator 7 reliably dissipates heat and cools down the cold end of the temperature difference power generation module 3; and a circulation portion for air flow is formed between the radiator and the mounting hole. When the burner is working, the external air can flow through the radiator at a faster speed and flow to the burner through the circulation portion, thereby improving the heat dissipation effect of the radiator 7 itself while further improving the heat dissipation and cooling effect of the radiator 7 on the cold end of the temperature difference power generation module 3.

[0103] The shape and structure of the mounting hole 1411 can be adapted to the outer contour of the radiator 7. For example, when the outer contour of the radiator 7 is rectangular, the shape of the mounting hole 1411 can also be rectangular. The size of the mounting hole 1411 can be equal to or greater than the cross-sectional size of the outer contour of the radiator 7.

[0104] Specifically, the mounting hole 1411 has a left side wall and a right side wall opposite to each other. In addition, the mounting hole 1411 may also have a front side wall and a rear side wall, and the left side wall, the front side wall, the right side wall and the rear side wall may be sequentially connected to form a rectangular opening. A left circulation portion 1413 is formed between the left side wall and the radiator 7, and a right circulation portion 1414 is formed between the right side wall and the radiator 7.

[0105] When the stove is working, taking the case where the left burner 11 and the right burner 12 are both in the start-up state as an example, when forming a primary wind, the external normal temperature air is introduced into the shell 10 through the left circulation part 1413 and the right circulation part 1414 to guide the left burner 11 and the right burner 12. At least part of the air can contact the radiator 7, and then pass through the left circulation part 1413 and the right circulation part 1414 to guide the left burner 11 and the right burner 12. In this way, it can be ensured that the air flowing into the shell 10 from the outside is in contact with the radiator 7 for heat exchange during the inflow process, so as to reliably control the temperature rise of the radiator 7, and further enhance the heat dissipation and cooling effect of the radiator 7 on the cold end of the temperature difference power generation module 3.

[0106] In a specific embodiment, the radiator 7 has a plurality of heat dissipation fins 72 arranged at intervals, the heat dissipation fins 72 at least partially protrude from the bottom case 14, and the heat dissipation fins 72 extend in the left-right direction to form an air flow channel 720 in the left-right direction. External normal temperature air can flow through the air flow channel 720 and then flow to the left burner 11 and the right burner 12 through the left circulation portion 1413 and the right circulation portion 1414 respectively.

[0107] In this embodiment, the radiator 7 includes a plurality of heat dissipation fins 72 arranged at intervals. When the radiator 7 is installed in place, the heat dissipation fins 72 are arranged along the left-right direction (i.e. Figure 3 The heat dissipation fins 72 extend in the first direction X) and at least partially protrude from the bottom shell 14, and an airflow channel 720 is formed between two adjacent heat dissipation fins 72 in the left and right directions. The extension direction of the airflow channel 720 is directly toward the left burner 11 and the right burner 12.

[0108] When the stove is working, due to the injection effect of the nozzle, a part of the external normal temperature air can pass through the air flow channel 720 at a faster flow rate and flow to the left burner 11 and the right burner 12 through the left flow portion 1413 and the right flow portion 1414 respectively. A part of the external normal temperature air can also flow directly to the left burner 11 and / or the right burner 12 through the left flow portion 1413 and the right flow portion 1414.

[0109] For example, taking the case where both the left burner 11 and the right burner 12 are in working condition, under the induced action of the nozzle of the left burner 11, a part of the external normal temperature air can pass through the airflow channel 720 and the left circulation portion 1413 at a faster speed, and directly flow to the left burner 11 through the left circulation portion 1413; under the induced action of the nozzle of the right burner 12, a part of the external normal temperature air can pass through the airflow channel 720 and the right circulation portion 1414 at a faster speed, and directly flow to the right burner 12 through the right circulation portion 1414.

[0110] Taking the case where only the left burner 11 is in working state, under the injection effect of the nozzle of the left burner 11, the external normal temperature air can flow through the air flow channel 720 through the left flow portion 1413 and the right flow portion 1414 to flow to the left burner 11 at a faster speed. In addition, part of the normal temperature air can also flow directly through the left flow portion 1413 to the left burner 11 at a faster speed.

[0111] Taking the case where only the right burner 12 is in working state, under the injection action of the nozzle of the right burner 12, the external normal temperature air can flow through the air flow channel 720 through the left flow portion 1413 and the right flow portion 1414 to the right burner 12 at a faster speed. In addition, part of the normal temperature air can also flow directly through the right flow portion 1414 to the right burner 12 at a faster speed.

[0112] In this way, it is equivalent to utilizing the heat dissipation fins 72 of the radiator 7, the cooperation between the radiator 7 and the bottom shell 14 to form a primary air flow channel for supplying air to the burner, and while forming the primary air flow channel, it can enable the normal temperature air flowing in from the outside to flow through the air flow channel 720 between the heat dissipation fins 72, thereby reliably and efficiently dissipating heat and cooling the heat dissipation fins 72, thereby ensuring that the temperature of the cold end of the temperature difference power generation module 3 is controlled at a lower temperature.

[0113] Among them, since the heat dissipation fins 72 are arranged along the left-right direction (i.e. Figure 3 The first direction X) of the heat dissipation fin 72 is extended, which is also conducive to the air flowing through the heat dissipation fin 72 to be accurately guided to the left burner 11 and / or the right burner 12 with a shorter path and lower resistance.

[0114] like Fig. 9 As shown, in addition, the mounting hole 1411 also has a front side wall and a rear side wall opposite to each other. The front side wall and the rear side wall are both provided with flanges 1412, and the flanges 1412 are used to connect with the radiator 7.

[0115] Specifically, at least one connector may be provided on the flange 1412, and the flange 1412 may be connected to the radiator 7 by means of the connector. For example, taking the flange 1412 of the front side wall as an example, the flange 1412 may be provided with two openings, and each opening may be connected to the radiator 7 and the bottom case 14 by means of a connector. The connector may be in the form of a detachable connection such as a bolt or a screw, or in other forms, and the present application does not make any specific limitation here.

[0116] like Figure 4 As shown, in one embodiment, a boss 143 is disposed in the middle of the bottom shell 14 , the boss 143 is protruded from the outside to the inside, and the mounting hole 1411 is disposed on the boss 143 .

[0117] In this embodiment, a boss 143 protruding from the outside to the inside may be provided in the middle of the bottom surface 141 of the bottom shell 14 , and the mounting hole 1411 may be provided on the boss 143 . Since the radiator 7 is installed in the mounting hole 1411, after the radiator 7 is inserted into the mounting hole 1411, part of the radiator 7 protrudes from the bottom surface 141. When the boss 143 is protruded inward, the radiator 7 protruding from the bottom surface 141 can be prevented from interfering with the external installation environment. In addition, when a boss 143 protruding from the outside to the inside is provided and the radiator 7 is inserted into the mounting hole 1411 of the boss 143, it is equivalent to using the boss 143 to form an air circulation portion higher than other positions of the bottom surface 141. External air can flow through the air circulation portion to the air flow channel 720, the left circulation portion 1413 and the right circulation portion 1414 of the radiator 7 more smoothly and reliably with lower resistance, thereby being able to dissipate heat and cool the radiator 7 more reliably and efficiently, thereby ensuring that the cold end temperature of the thermoelectric power generation module 3 is controlled at a lower temperature.

[0118] In addition, if Figure 4 As shown, in some other embodiments, the bottom shell 14 may further include a bottom surface 141 and a side surface 142 surrounding the bottom surface 141 , and an inlet 1421 is opened on the side surface 142 .

[0119] By setting the inlet 1421 on the side 142, when the cooker is in use, under the injection action of the nozzle, the normal temperature air outside the shell 10 can also enter the shell 10 through the inlet 1421 and flow to the left burner 11 and the right burner 12 to realize the air intake function.

[0120] Specifically, the inlet 1421 is arranged close to the radiator 7, or the projection of the radiator 7 toward the side 142 at least partially overlaps with the inlet 1421, so that the external normal temperature air can first flow through the radiator 7 when flowing into the shell 10 through the air inlet, dissipate the heat of the radiator 7, and then flow to the left burner 11 and the right burner 12.

[0121] Please refer to Figure 4 , Figure 7 and Fig.10 In one embodiment, the burner includes a left burner 11 located on the left side of the waste heat recovery stove and a right burner 12 located on the right side of the waste heat recovery stove; the temperature difference power generation module 3 is arranged between the left burner 11 and the right burner 12.

[0122] The heat collector comprises: a left heat collector 41 disposed near the left burner 11 and a right heat collector 42 disposed near the right burner 12. A left liquid receiving pan 15 is disposed around the left burner 11, and a right liquid receiving pan 16 is disposed around the right burner 12.

[0123] Wherein, the left through hole 151 is provided on the left liquid receiving pan 15, and the left heat collector 41 includes a left main heat receiving part 411 capable of passing through the left through hole 151 to directly absorb the heat of the left burner 11, and a left auxiliary heat receiving part 412 capable of contacting the left liquid receiving pan 15 to indirectly absorb the heat of the left burner 11 through the left liquid receiving pan 15; specifically, the left heat collector 41 is connected to the left liquid receiving pan 15, and the left auxiliary heat receiving part 412 is connected to the hot end of the temperature difference power generation module 3 through the left heat pipe 511; the left heat collector 41 is connected to the left liquid receiving pan 15 through the left auxiliary heat receiving part 412, and the left auxiliary heat receiving part 412 is located below the left liquid receiving pan 15; And / or, a right through hole 161 is provided on the right liquid receiving pan 16, and the right heat collector 42 includes a right main heat receiving part 421 that can pass through the right through hole 161 to directly absorb the heat of the right burner 12, and a right auxiliary heat receiving part 422 that can contact the right liquid receiving pan 16 to indirectly absorb the heat of the right burner 12 through the right liquid receiving pan 16; the right heat collector 42 is connected to the right liquid receiving pan 16, and the right auxiliary heat receiving part 422 is connected to the hot end of the temperature difference power generation module 3 through the right heat pipe 521; specifically, the right heat collector 42 is connected to the right liquid receiving pan 16 through the right auxiliary heat receiving part 422, and the right auxiliary heat receiving part 422 is located below the right liquid receiving pan 16.

[0124] In this embodiment, taking the left heat collector 41 as an example, its left main heat receiving part 411 can directly absorb the heat generated by the left burner 11 when it is working by means of thermal radiation, and at the same time, its left auxiliary heat receiving part 412 is connected to the left liquid receiving pan 15, and can absorb the heat of the left liquid receiving pan 15 by means of heat transfer. The heat from multiple sources is superimposed, so that the left heat collector 41 achieves a better waste heat absorption effect. Taking the right heat collector 42 as an example, its right main heat receiving part 421 can directly absorb the heat generated by the right burner 12 when it is working by means of thermal radiation, and at the same time, its right auxiliary heat receiving part 422 is connected to the right liquid receiving pan 16, and can absorb the heat of the right liquid receiving pan 16 by means of heat transfer. The heat from multiple sources is superimposed, so that the right heat collector 42 achieves a better waste heat absorption effect.

[0125] In a specific embodiment, the left auxiliary heating part 412 includes a left flange portion, which is connected and fitted to the lower surface of the left liquid receiving pan 15 through a connecting piece, and / or the right auxiliary heating part 422 includes a right flange portion, which is connected and fitted to the lower surface of the left liquid receiving pan 15 through a connecting piece.

[0126] In this embodiment, the left auxiliary heat receiving portion 412 may include a left flange portion, and the extension direction of the left flange portion may be consistent with the extension direction of the lower surface of the left liquid receiving pan 15, so that the left flange portion and the lower surface of the left liquid receiving pan 15 can be well fitted; after the two are fitted, they can be connected by setting a connecting piece. For example, when the connecting piece is in the form of a screw, an opening for installing the connecting piece can be set on the left flange portion and the left liquid receiving pan 15.

[0127] The right auxiliary heat receiving portion 422 may include a right flange portion, and the extension direction of the right flange portion may be consistent with the extension direction of the lower surface of the right liquid receiving pan 16, so that the right flange portion and the lower surface of the right liquid receiving pan 16 can be well fitted; after the two are fitted, they can be connected by setting a connecting piece. For example, when the connecting piece is in the form of a screw, an opening for installing the connecting piece can be set on the right flange portion and the right liquid receiving pan 16.

[0128] In one embodiment, the left main heat receiving part 411 and the left burner 11 are concentrically arranged, and the central angle of the left main heat receiving part is an acute angle; and / or, the right main heat receiving part 421 and the right burner 12 are concentrically arranged, and the central angle of the right main heat receiving part 421 is an acute angle.

[0129] In this embodiment, the left main heat receiving part 411 can be arranged concentrically with the left burner 11, so as to evenly absorb the heat of the left burner 11, and also make the left main heat receiving part 411 fit the installation position without interference and other problems. Similarly, the right main heat receiving part 421 can also be arranged concentrically with the right burner 12.

[0130] Specifically, taking the left main heat receiving part 411 as an example, the center angle of the left main heat receiving part is an acute angle, the projection of the left main heat receiving part 411 toward the left liquid receiving pan 15 is fan-shaped as a whole, and the center angle of the left main heat receiving part 411 is 20° to 60°;

[0131] When the left main heat receiving part 411 is fan-shaped, the central angle of the fan is not less than 20° to ensure that the left main heat receiving part 411 has sufficient heating area to absorb the heat from the left burner 11; in addition, the central angle of the fan is not greater than 60°, and the left main heat receiving part 411 will not cause excessive obstruction, so that when the left burner 11 burns, sufficient oxygen can be guaranteed and the combustion is complete.

[0132] Of course, the embodiment of the present application does not exclude the case where the center angle of the left main heat receiving portion 411 slightly exceeds the above range. When the center angle of the left main heat receiving portion 411 slightly exceeds the above range, the effect substantially the same as the above boundary value may be achieved.

[0133] The center angle of the right main heat receiving part 421 is an acute angle, and the projection of the right main heat receiving part 421 toward the right liquid receiving pan 16 is fan-shaped as a whole, and the center angle of the right main heat receiving part 421 is 20° to 60°. The preferred setting of the specific center angle of the right main heat receiving part 421 can refer to the description of the center angle of the left main heat receiving part 411, and the present application will not repeat it here.

[0134] In one embodiment, the left burner 11 is provided with a left liquid tray 15; the right burner 12 is provided with a right liquid tray 16, and the minimum distance from the edge of the left liquid tray 15 to the center line of the stove is the left distance. The minimum distance from the edge of the right liquid tray 16 to the center line of the stove is the right distance. The center line of the stove can be Figure 3 As shown in FIG. 1 , the perpendicular midline EE in the second direction Y perpendicular to the left-right direction (first direction X). In this embodiment, the left burner 11 and the right burner 12 of the cooker are symmetrically arranged about the midline (perpendicular midline EE).

[0135] The left burner 11 has a left inner gas outlet and a left outer gas outlet, the left inner gas outlet is provided with a left inner fire cover, the left outer gas outlet is provided with a left outer fire cover, and a left annular gap is formed between the left inner fire cover and the left outer fire cover.

[0136] The left heat collector 41 is arranged close to the left burner 11 and includes any one of the following or a combination thereof: the left heat collector 41 is located in the range from the edge of the left liquid receiving pan 15 to half of the left side spacing; the left heat collector 41 is located as a whole on the left liquid receiving pan 15 and is connected to the left liquid receiving pan 15; a left through hole 151 is opened on the left liquid receiving pan 15, and the left heat collector 41 is penetrated by the left through hole 151 and is connected to the left liquid receiving pan 15; at least a part of the left heat collector 41 is located in the left annular gap.

[0137] The right heat collector 42 is arranged close to the right burner 12 and includes any one of the following or a combination thereof: the right heat collector 42 is located in the range from the edge of the right liquid receiving pan 16 to half of the right side spacing; the right heat collector 42 is located as a whole on the right liquid receiving pan 16 and is connected to the right liquid receiving pan 16; a right through hole 161 is opened on the right liquid receiving pan 16, and the right heat collector 42 is penetrated through the right through hole 161 and is connected to the right liquid receiving pan 16; at least part of the right heat collector 42 is located in the right annular gap.

[0138] In this embodiment, taking the setting position of the left heat collector 41 as an example, the setting position of the left heat collector 41 close to the left burner 11 may include various situations. Figure 4 and Fig.10 As shown, and as described in the above-mentioned embodiments, the left liquid receiving pan 15 is provided with a left through hole 151, and the left heat collector 41 is inserted into the left through hole 151 and is connected to the left liquid receiving pan 15. Alternatively, the left liquid receiving pan 15 may also be partially provided with through holes, and the left heat collector 41 may be fixed on the upper surface of the left liquid receiving pan 15. Alternatively, the left heat collector 41 may be located between the left liquid receiving pan 15 and the center line of the stove, and relatively close to the left liquid receiving pan 15. Alternatively, the left heat collector 41 may also be arranged in the left annular gap to absorb the heat generated by the combustion of the left inner fire cover and the left outer fire cover.

[0139] Similarly, the position where the right heat collector 42 is disposed close to the left burner 11 may also include a variety of situations. Specifically, reference may be made to the description of the left heat collector 41 above, and the present application will not elaborate on it here.
