Description

Technical Field

[0001] This application relates to the field of gas stove technology, and in particular to a gas stove with a high-efficiency pot rack. Background Technology

[0002] As an essential kitchen appliance in daily life, high combustion thermal efficiency has become one of the development directions for gas stoves. To improve combustion thermal efficiency, existing gas stoves generally use a disc-shaped pot rack, and some even use three or more layers of disc-shaped pot racks. This concentrates the high-temperature heat energy of combustion within the disc, reduces the radiative heat exchange of combustion energy to the surroundings, and also plays a role in heat insulation and heat preservation, reducing heat loss. This enhances the heat exchange intensity between combustion energy and the bottom of the pot, thereby improving combustion thermal efficiency.

[0003] However, existing multi-layer pan racks with three or more layers have problems such as poor heat insulation, large heat loss, and low heat utilization due to unreasonable structural design between layers, resulting in low combustion thermal efficiency. Summary of the Invention

[0007] Furthermore, the energy-concentrating disk body includes an upper disk and a middle disk, both of which are annular, with the middle disk coaxially disposed below the upper disk;

[0008] The outer edge of the upper disk is higher than the inner edge, so that the upper disk forms a concave energy-concentrating cavity;

[0009] The inner edge of the upper disk is connected to the inner edge of the middle disk, and the outer edge of the upper disk is connected to the outer edge of the middle disk, so that the upper disk and the middle disk form the first annular cavity.

[0010] Furthermore, the inner edge of the upper disk is perpendicularly connected to the inner edge of the middle disk;

[0011] Alternatively, both the inner edge of the upper disk and the inner edge of the middle disk are formed with inner narrow rings, and the inner narrow rings of the middle disk are abutted and connected to the inner narrow rings of the upper disk.

[0012] Furthermore, the outer edge of the upper disk is perpendicularly connected to the outer edge of the middle disk;

[0013] Alternatively, both the outer edge of the upper disk and the outer edge of the middle disk are formed with a narrow outer ring, and the narrow outer ring of the middle disk is abutted and connected to the narrow outer ring of the upper disk.

[0014] Furthermore, the lower disk has an upward-facing annular cavity, the inner edge of the lower disk extends to the inner side of the energy-concentrating disk body, the outer edge of the lower disk extends to the outer side of the energy-concentrating disk body, and the inner edge of the lower disk is folded upward to form an inner edge flange, and the outer edge of the lower disk is folded upward to form an outer edge flange.

[0015] Furthermore, the inner edge of the lower disk is lower than the inner edge of the energy-concentrating disk body, and the outer edge of the lower disk is lower than the outer edge of the energy-concentrating disk body.

[0016] Furthermore, the energy-concentrating pan rack also includes a heat-insulating connection assembly; the heat-insulating connection assembly is disposed between the energy-concentrating pan body and the lower pan, and the lower pan is connected to the energy-concentrating pan body through the heat-insulating connection assembly.

[0017] Furthermore, the heat-insulating connection assembly includes a connector, a heat-insulating component, and a fixing foot; the connector is disposed between the energy-concentrating disk body and the lower disk and is fixedly connected to the energy-concentrating disk body, and the lower end of the connector abuts against the lower disk through the heat-insulating component; the lower disk and the heat-insulating component have coaxial mounting holes, and the connector has an internally threaded connection hole coaxial with the mounting hole; the fixing foot is disposed below the lower disk, and the fixing foot has a connecting screw, which passes through the mounting holes of the lower disk and the heat-insulating component and is screwed into the internally threaded connection hole; there are multiple heat-insulating connection assemblies, and the multiple heat-insulating connection assemblies are distributed circumferentially around the lower disk.

[0018] The present invention also provides a gas stove, including the energy-concentrating pot rack described in any of the above claims.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] The energy-concentrating pan holder provided by this invention includes an energy-concentrating pan body and a lower pan. Both the energy-concentrating pan body and the lower pan are annular, and the lower pan is coaxially disposed on one side of the energy-concentrating pan body. In use, the energy-concentrating pan body and the lower pan are coaxially arranged around the outside of the burner of the gas stove, with the lower pan located on the side of the energy-concentrating pan body away from the pot, i.e., below the energy-concentrating pan body. The upper surface of the energy-concentrating pan body has a recessed energy-concentrating cavity. When the burner burns to heat the pot, the high-temperature flue gas generated by combustion can be concentrated in the energy-concentrating cavity, allowing the high-temperature flue gas to exchange heat with the bottom of the pot, thereby reducing heat loss to a certain extent and improving combustion thermal efficiency.

[0021] The main body of the energy-concentrating disk has a first annular cavity inside. This first annular cavity is a sealed chamber filled with air. Utilizing the poor thermal conductivity of air, it prevents heat from being conducted downwards from the upper part of the energy-concentrating disk, thus providing insulation for the high-temperature flue gas in the upper energy-concentrating cavity and enhancing the energy-concentrating effect. A second annular cavity is formed between the lower disk and the main body of the energy-concentrating disk. An inner edge opening connects the inner edge of the lower disk and the inner edge of the main body of the energy-concentrating disk to the second annular cavity, allowing air within the second annular cavity to communicate with the outside through this inner edge opening, which faces upwards.

[0022] The second annular cavity is located below the first annular cavity. When the burner is burning, although the first annular cavity has the function of heat insulation, the heat energy in the energy-concentrating cavity will inevitably be conducted downward to the second annular cavity, which will heat the air in the second annular cavity. As a result, the air in the second annular cavity will expand due to heat and generate a certain amount of flow, and flow out from the inner annular opening. Since the opening of the inner annular opening is facing upward, the air will flow upward along the inner annular opening to the burner to participate in combustion. Moreover, since this part of the air has been preheated in the second annular cavity, its participation in combustion can increase the flame temperature to a certain extent, thereby further improving the combustion thermal efficiency.

[0023] The present invention also provides a gas stove, including the aforementioned energy-concentrating pot rack, thus the gas stove also has the beneficial effects of the energy-concentrating pot rack. Attached Figure Description

[0035] The following reference Figures 1 to 3 This application describes a pot holder and gas stove according to some embodiments.

[0036] This application provides a pot holder for concentrating energy, such as Figures 1 to 3 As shown, it includes a main body 1 of the energy-concentrating plate and a lower plate 2. Both the main body 1 and the lower plate 2 are annular, and the lower plate 2 is coaxially arranged on one side of the main body 1 of the energy-concentrating plate. In use, the main body 1 of the energy-concentrating plate and the lower plate 2 are coaxially arranged around the outside of the burner 4 of the gas stove, and the lower plate 2 is located on the side of the main body 1 of the energy-concentrating plate away from the pot, that is, the lower plate 2 is located below the main body 1 of the energy-concentrating plate.

[0037] The surface of the energy-concentrating plate body 1 facing the cookware, i.e. the upper surface of the energy-concentrating plate body 1, has a recessed energy-concentrating cavity 13. When the burner 4 burns to heat the cookware, the high-temperature flue gas generated by combustion can be concentrated in the energy-concentrating cavity 13, so that the high-temperature flue gas can exchange heat with the bottom of the pot, thereby reducing heat loss to a certain extent and improving combustion thermal efficiency.

[0038] The main body 1 of the energy-concentrating disk has a first annular cavity 14 inside. The first annular cavity 14 is a sealed chamber and is filled with air. By utilizing the poor thermal conductivity of air, the heat energy above the main body 1 of the energy-concentrating disk is blocked from being conducted downwards, which can play a role in heat insulation and heat preservation for the high-temperature flue gas in the upper energy-concentrating cavity 13, thereby enhancing the energy-concentrating effect.

[0039] In this embodiment, preferably, at least one partition (not shown in the figure) is provided in the first annular cavity 14 to divide the first annular cavity 14 into multiple layers from top to bottom, so that the energy-concentrating disk body 1 forms a multi-layer heat-insulating cavity, so as to achieve multiple heat preservation and improve the heat preservation and energy-concentrating effect.

[0040] like Figure 2 and Figure 3As shown, a second annular cavity 21 is formed between the lower disk 2 and the energy-concentrating disk body 1. Both the lower disk 2 and the energy-concentrating disk body 1 have inner edges along their own radial direction. The inner diameter of the lower disk 2 is smaller than the inner diameter of the energy-concentrating disk body 1, so that the inner edge of the lower disk 2 extends to the inner side of the energy-concentrating disk body 1. An inner edge annular opening 22 that communicates with the second annular cavity 21 is formed between the inner edge of the lower disk 2 and the inner edge of the energy-concentrating disk body 1. This allows the air in the second annular cavity 21 to communicate with the outside through the inner edge annular opening 22, and the opening direction of the inner edge annular opening 22 is upward.

[0041] The second annular cavity 21 is located below the first annular cavity 14. When the burner 4 is burning, although the first annular cavity 14 has the function of heat insulation, the heat energy in the energy-concentrating cavity 13 will inevitably be conducted downward to the second annular cavity 21, which will heat the air in the second annular cavity 21. As a result, the air in the second annular cavity 21 will expand due to heat and generate a certain amount of flow, and flow out from the inner annular opening 22. Since the opening of the inner annular opening 22 is facing upward, the air will flow upward along the inner annular opening 22 to the burner 4 to participate in combustion. And because this part of the air has been preheated in the second annular cavity 21, its participation in combustion can increase the flame temperature to a certain extent, thereby further improving the combustion thermal efficiency.

[0042] In one embodiment of this application, preferably, as shown below, Figure 3 As shown, the lower plate 2 and the energy-concentrating plate body 1 each have an outer edge along their radial direction. The outer diameter of the lower plate 2 is larger than the outer diameter of the energy-concentrating plate body 1, so that the outer edge of the lower plate 2 extends to the outer side of the energy-concentrating plate body 1, forming an outer edge annular opening 23 that communicates with the second annular cavity 21 between the outer edge of the lower plate 2 and the outer edge of the energy-concentrating plate body 1, and the opening direction of the outer edge annular opening 23 is upward. When the air in the second annular cavity 21 is heated and flows, a part of the hot air flows out from the inner edge annular opening 22, and another part of the hot air flows out from the outer edge annular opening 23 and flows upward toward the bottom of the pot, thereby forming an air curtain around the energy-concentrating plate body 1 at the bottom of the pot, preventing the high-temperature flue gas in the energy-concentrating cavity 13 from exchanging heat with the outside cold air and reducing heat loss. At the same time, the upward flowing hot air can also guide the combustion heat energy gas mass, i.e., the high-temperature flue gas, upward to the bottom of the pot, enhancing the heat exchange intensity between the high temperature gas and the bottom of the pot, so that the heat energy of the high-temperature flue gas can be fully utilized.

[0043] Therefore, the structure of the energy-concentrating pan and pot frame of this application can optimize the heat preservation and energy concentration effect of the energy-concentrating cavity 13, thereby improving the thermal energy utilization rate and combustion thermal efficiency.

[0044] In this embodiment, preferably, as follows: Figure 2 and Figure 3As shown, the inner diameter of the main body 1 of the energy-concentrating plate and the inner diameter of the lower plate 2 are both larger than the outer diameter of the burner 4. Thus, when the energy-concentrating plate is fitted on the outside of the burner 4, an annular gap is formed between the energy-concentrating plate and the burner 4, which serves as the inlet for the secondary air required for combustion, ensuring complete combustion.

[0045] In one embodiment of this application, preferably, the energy-concentrating disk body 1 includes an upper disk 11 and a middle disk 12. Both the upper disk 11 and the middle disk 12 are annular. The middle disk 12 is coaxially disposed below the upper disk 11, and the inner edge of the middle disk 12 is connected to the inner edge of the upper disk 11, and the outer edge of the middle disk 12 is connected to the outer edge of the upper disk 11, so that a closed first annular cavity 14 is formed between the middle disk 12 and the upper disk 11. At the same time, the outer edge of the upper disk 11 is higher than the inner edge, so that the upper disk 11 forms a concave energy-concentrating cavity 13.

[0046] In this embodiment, such as Figure 1 and Figure 2 As shown, the upper plate 11 is provided with multiple pot supports 15, which are distributed in a circular interval around the upper plate 11 to provide stable support for the pots.

[0047] Regarding the connection between the inner edge of the upper disk 11 and the inner edge of the middle disk 12, in this embodiment, preferably, the inner edges of the upper disk 11 and the middle disk 12 are each formed with a narrow inner ring edge, for example, the width of the narrow inner ring edge is 0.45mm-1mm; the narrow inner ring edge of the middle disk 12 is closely connected to the narrow inner ring edge of the upper disk 11, thereby reducing the contact area at the connection between the inner edges of the upper disk 11 and the middle disk 12 to a certain extent, so as to reduce the heat loss caused by heat conduction.

[0048] Alternatively, both the upper disk 11 and the middle disk 12 may have a relatively thin thickness. When connecting the inner edges of the upper disk 11 and the middle disk 12, the inner edges of the upper disk 11 and the middle disk 12 may be perpendicularly connected; for example, as... Figure 3 As shown, the inner edge of the upper plate 11 extends horizontally, and the inner edge of the middle plate 12 is folded to form a vertical flange, so that the inner edge of the upper plate 11 and the vertical flange of the inner edge of the middle plate 12 are perpendicularly connected, thereby reducing the contact area at the connection of the inner edges of the two to a certain extent and reducing the heat loss caused by heat conduction.

[0049] Preferably, the thickness of the upper plate 11 and the middle plate 12 is 0.45mm-0.8mm, so as to ensure that the upper plate 11 and the middle plate 12 have sufficient strength and minimize their contact area.

[0050] The connection between the outer edge of the upper disk 11 and the outer edge of the middle disk 12 can also adopt the above-mentioned inner edge connection method, that is, as follows: Figure 3The outer edge of the upper plate 11 and the outer edge of the middle plate 12 are vertically connected, or the outer narrow edge of the middle plate 12 is attached to the outer narrow edge of the upper plate 11, thereby reducing the contact area at the connection between the outer edges of the upper plate 11 and the middle plate 12 to a certain extent and reducing the heat loss caused by heat conduction.

[0051] In one embodiment of this application, preferably, as shown below, Figure 3 As shown, the lower disk 2 forms an upward-facing annular cavity. The inner edge of the lower disk 2 extends to the inner side of the energy-concentrating disk body 1, and the outer edge of the lower disk 2 extends to the outer side of the energy-concentrating disk body 1, so that the lower end of the energy-concentrating disk body 1 is surrounded by the lower disk 2, thereby forming a second annular cavity 21 between the lower disk 2 and the energy-concentrating disk body 1. The inner edge annular opening 22 of the second annular cavity 21 is formed between the inner edge of the lower disk 2 and the inner edge of the energy-concentrating disk body 1, and the outer edge annular opening 23 of the second annular cavity 21 is formed between the outer edge of the lower disk 2 and the outer edge of the energy-concentrating disk body 1.

[0052] In this embodiment, such as Figure 3 As shown, the inner edge of the lower plate 2 has an upwardly folded inner edge flange 24, and the outer edge of the lower plate 2 has an upwardly folded outer edge flange 25, so that the opening directions of the inner edge ring 22 and the outer edge ring 23 are both upward.

[0053] In this embodiment, preferably, the distance between the inner edge flange 24 of the lower plate 2 and the inner edge of the energy-concentrating plate body 1 is 2mm-4.5mm, and the distance between the outer edge flange 25 of the lower plate 2 and the outer edge of the energy-concentrating plate body 1 is 2mm-4.5mm.

[0054] In one embodiment of this application, preferably, the inner edge of the lower disk 2 is lower than the inner edge of the energy-concentrating disk body 1, and the outer edge of the lower disk 2 is lower than the outer edge of the energy-concentrating disk body 1. For example, in Figure 3 In this configuration, the inner edge of the energy-concentrating disk body 1 is the inner edge of the upper disk 11, and the outer edge of the energy-concentrating disk body 1 is the outer edge of the upper disk 11. The inner edge of the lower disk 2 is located below the inner edge of the upper disk 11, and the outer edge of the lower disk 2 is located below the outer edge of the upper disk 11. This allows the energy-concentrating disk body 1 to shield the inner and outer edges of the lower disk 2 to a certain extent, preventing the outer and inner edges of the lower disk 2 from being directly radiated by combustion heat energy, thus avoiding heat dissipation problems and loss of combustion heat energy.

[0055] In this embodiment, preferably, the inner edge of the lower disk 2 is 3mm-5mm lower than the inner edge of the energy-concentrating disk body 1, and the outer edge of the lower disk 2 is 3mm-5mm lower than the outer edge of the energy-concentrating disk body 1.

[0056] In one embodiment of this application, preferably, as shown below, Figure 1 and Figure 3As shown, the lower plate 2 is detachably and coaxially connected to the lower part of the energy-concentrating plate body 1 via a heat-insulating connection assembly 3. Specifically, the heat-insulating connection assembly 3 includes a connector 31, a heat-insulating component 32, and a fixing foot 33. The connector 31 is located between the energy-concentrating plate body 1 and the lower plate 2, and one end of the connector 31 is fixedly connected to the energy-concentrating plate body 1, specifically to the middle plate 12 of the energy-concentrating plate body 1. The other end of the connector 31 abuts against the lower plate 2 via the heat-insulating component 32. The connector 31 has an internal threaded connection hole, and the lower plate 2 and the heat-insulating component 32 each have mounting holes coaxial with the internal threaded connection hole. The fixing foot 33 is located below the lower plate 2, and the fixing foot... The upper end of 33 is provided with a connecting screw. The connecting screw passes through the mounting holes of the lower plate 2 and the heat insulation component 32 and is screwed into the internal threaded connecting hole of the connector 31, so that the lower plate 2 is clamped between the connector 31 and the fixed foot 33, thereby realizing the connection between the lower plate 2 and the energy-concentrating plate body 1. The energy-concentrating plate pot rack can be supported on the gas stove countertop through the fixed foot 33. At the same time, the connector 31 abuts against the lower plate 2 through the heat insulation component 32, so that the heat insulation component 32 can block the contact heat transfer between the energy-concentrating plate body 1 and the lower plate 2, thereby reducing heat loss.

[0057] In this embodiment, preferably, there are multiple heat-insulating connection components 3, which are evenly distributed around the lower plate 2 in a circular pattern. This makes the connection between the lower plate 2 and the energy-concentrating plate body 1 more stable, and also allows the energy-concentrating plate pot rack to be stably supported on the gas stove panel. A predetermined gap is also created between the lower plate 2 and the gas stove panel to form a secondary air inlet channel, providing the necessary secondary air for combustion and making combustion more complete.

[0058] In this embodiment, preferably, the connector 31 is a non-metallic flame-retardant material with low thermal conductivity, such as polytetrafluoroethylene, flame-retardant PA66 (polyhexamethylene adipamide), etc., thereby reducing heat loss caused by heat conduction to a certain extent.

[0059] In this embodiment, preferably, the heat insulation element 32 is a heat insulation pad, such as an aerogel heat insulation pad or a mica heat insulation pad, so as to block the conduction of heat energy and reduce heat loss.

[0060] In one embodiment of this application, preferably, the lower disk 2 has at least a smooth mirror surface on its upper surface or is provided with a reflective layer, so as to improve the ability of the lower disk 2 to reflect heat to a certain extent, thereby reducing the heat absorbed by the lower disk 2. It also helps to heat the air in the second annular cavity 21 and helps to improve the heat insulation effect of the first annular cavity 14, thereby enhancing the temperature field of the energy-concentrating cavity 13 to a certain extent.

[0061] In this embodiment, preferably, at least the upper surface of the lower disk 2 is provided with a heat insulation layer, which can effectively prevent heat conduction, suppress and shield the heat loss caused by radiant heat and conductive heat, enhance the heat insulation effect of the first annular cavity 14, and thus enhance the temperature field of the energy-concentrating cavity 13 to a certain extent.

[0062] In this embodiment, preferably, the upper surface of the lower disk 2 is a smooth plane or has a reflective layer, and the lower surface of the lower disk 2 has a heat insulation layer, thereby improving the heat reflection capability of the lower disk 2 and reducing the heat absorbed by the lower disk 2; at the same time, it is beneficial to heat the air in the second annular cavity 21; it also helps to improve the heat insulation effect of the first annular cavity 14; and at the same time, it can effectively prevent the lower disk 2 from dissipating heat downwards and causing heat loss.

[0063] This application also provides a gas stove, including the energy-concentrating pot rack of any of the above embodiments.

[0064] In this embodiment, the gas stove includes an energy-concentrating pan and pot rack, and therefore the gas stove has all the beneficial effects of the energy-concentrating pan and pot rack, which will not be described in detail here.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
