Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, in particular to a gas stove and an energy-gathering bracket thereof. Background Art

[0002] A gas stove with a focused energy effect typically consists of a panel, a burner, and a focused energy support. The support and burner are mounted on the panel and support the cooking utensils. The focused energy support also has a premixing channel and a combustion channel. Gas flows through the premixing channel into the combustion channel, where it is burned by the burner. The focused energy support concentrates heat in the premixing and combustion channels, rapidly heating the cooking utensils.

[0003] However, existing technologies, whether high-end or low-end, generally achieve a heat transfer efficiency of 63%. With the strategic direction of energy conservation and environmental protection to achieve "carbon neutrality," the development of a gas stove with higher heat transfer efficiency has become a widespread concern and urgent problem in the field of household appliance technology. Summary of the Invention

[0004] Based on this, it is necessary to provide a gas stove with higher heat conduction efficiency and an energy-gathering bracket thereof in order to address the above-mentioned problem of insufficient heat conduction efficiency.

[0005] An energy-gathering bracket, comprising:

[0006] An energy concentrator having an inner side with a premixing surface and a combustion surface connected to each other, the premixing surface being configured to form a premixing channel with the outer wall of the cooking appliance, and the combustion surface being configured to form a combustion channel with the outer wall of the cooking appliance, the premixing channel and the combustion channel being sequentially arranged and connected along the flow direction of the gas, and the diameter of the premixing channel gradually decreasing along the flow direction of the gas; and

[0007] The spoiler assembly is accommodated in the combustion channel and protrudes from the combustion surface.

[0008] In one embodiment, the energy concentrating member further has an expansion surface, which is configured to be used to enclose an expansion channel with the outer wall surface of the cooking utensil, and the expansion channel is connected between the premixing channel and the combustion channel, and the diameter of the expansion channel is larger than the diameter of the opening connecting the premixing channel and the expansion channel.

[0009] In one embodiment, the diameter of the expansion channel gradually increases along the flow direction of the gas.

[0010] In one embodiment, the expansion channel is transitionally connected to the premixing channel.

[0011] In one embodiment, the spoiler assembly includes a plurality of spoilers, and the plurality of spoilers are spaced apart along the circumference of the energy concentrating member.

[0012] In one embodiment, there are at least two flow-turbulating components, and all of the flow-turbulating components are arranged at intervals along the flow direction of the gas.

[0013] In one embodiment, it further includes an inner insulation layer and / or an outer insulation layer, the energy concentrating member has an inner surface including the premixing surface and the combustion surface, the inner insulation layer covers the inner surface, and the outer insulation layer covers the outer surface of the energy concentrating member facing away from the inner surface.

[0014] In one embodiment, an air intake channel is provided on the energy concentrating member, and the air intake channel is connected between one of the premixing channel and the combustion channel and the outside.

[0015] In one embodiment, the energy concentrator has a double-layer structure and includes an inner wall and an outer wall. The inner wall has an inner surface including the premixing surface and the combustion surface. The outer wall is connected to a side of the inner wall facing away from the inner surface and encloses the inner wall to form a preheating chamber.

[0016] An air inlet hole is provided on the outer side wall, and an air outlet hole is provided on the inner side wall. The air inlet hole, the preheating chamber and the air outlet hole are connected in sequence to form the air inlet channel.

[0017] A gas stove comprises the energy concentrating bracket as described in any one of the above embodiments.

[0018] In the above-mentioned gas stove and its energy-gathering bracket, the diameter of the premixing channel gradually decreases along the flow direction of the gas. When the flow rate remains unchanged, the gas speed gradually increases as it passes through the premixing channel, allowing the gas to flow into the combustion channel at a high speed. Furthermore, because the spoiler assembly is housed in the combustion channel and protrudes from the combustion surface, the high-speed flowing gas is stirred and switched to a turbulent state under the action of the spoiler assembly. The turbulent gas continuously impacts the convection layer adhered to the outer wall of the cooking vessel, making the convection layer thinner, thereby enabling faster and more heat to be transferred to the cooking vessel. Therefore, the gas stove and its energy-gathering bracket in this application have higher heat conduction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Please also refer to Figure 1 and Figure 2 The present application provides a gas stove 1, which includes a panel (not shown), a burner 200, and an energy-concentrating bracket 100. The energy-concentrating bracket 100 and the burner 200 are both mounted on the panel. The energy-concentrating bracket 100 is used to support a cooking utensil 300 and concentrate energy, and the burner 200 is used to inject and ignite gas to heat the cooking utensil 300. It should be understood that the gas mentioned in this application refers to a mixed gas formed by a mixture of combustion gas and air.

[0031] The energy concentrator support 100 includes an energy concentrator 10 and a flow disturbance assembly 20. The energy concentrator 10 is supported on a panel and is used to support the cooking utensil 300 and the energy concentrator. The flow disturbance assembly 20 is mounted inside the energy concentrator 10 and is used to disturb the gas. The inner side of the energy concentrator 10 has a premixing surface 112 and a combustion surface 114 connected to each other. The premixing surface 112 is configured to form a premixing channel 123 with the outer wall 310 of the cooking utensil 300. The combustion surface 114 is configured to form a combustion channel 125 with the outer wall 310 of the cooking utensil 300. The premixing channel 123 and the combustion channel 125 are arranged along the flow direction of the gas (e.g., Figure 1 The premixing channel 123 is arranged and connected in sequence (in the direction indicated by the straight arrow in the figure), and the diameter of the premixing channel 123 gradually decreases along the flow direction of the gas; the spoiler assembly 20 is accommodated in the combustion channel 125 and protrudes from the combustion surface 114.

[0032] Specifically, the energy concentrator 10 is a hollow structure with an inner surface 111, which encloses an energy concentrator cavity 12. The energy concentrator 10 has a first mounting opening 121 located near the panel and a second mounting opening 122 located farther from the panel. Both the first mounting opening 121 and the second mounting opening 122 communicate with the energy concentrator cavity 12. The burner 200 is supported on the panel, with the first mounting opening 121 extending into the energy concentrator cavity 12. A cooking appliance 300 is supported on the energy concentrator 10, specifically via legs (not shown) provided on the energy concentrator 10. The cooking appliance 300 is inserted through the second mounting opening 122 and at least partially accommodated within the energy concentrator cavity 12. Furthermore, the cooking appliance 300 is spaced apart from the burner 200. The inner surface 111 includes a predetermined surface and a combustion surface 114, which are interconnected. The predetermined surface is located near the panel, while the combustion surface 114 is located farther from the panel. The premixing surface 112 and the outer wall 310 of the cooking vessel 300 enclose a premixing channel 123, and the combustion surface 114 and the outer wall 310 of the cooking vessel 300 enclose a combustion channel 125. It will be appreciated that if the cooking vessel 300 is spaced apart from the inner surface 111, the premixing channel 123 and the combustion channel 125 are both closed annular channels. In other words, the premixing channel 123 and the combustion channel 125 each encircle the cooking vessel 300 along its circumference. If the cooking vessel 300 is partially in contact with the inner surface 111, the premixing channel 123 and the combustion channel 125 each are non-enclosed arcuate channels. In other words, the premixing channel 123 and the combustion channel 125 each extend along the circumference of the cooking vessel 300 but do not encircle it. The burner 200 is used to inject gas into the premixing channel 123 so that the gas can be further mixed with the air in the premixing channel 123 and then flow into the combustion channel 125. Then, the gas is burned in the combustion channel 125 under the action of the burner 200.

[0033] In a conventional energy concentrating support 100, when a cooking utensil 300 (e.g., a pot) is supported on the energy concentrating member 10 and extends into the energy concentrating cavity 12, the diameter of the premixing channel 123 formed by the outer wall 310 of the cooking utensil 300 and the premixing surface 112 remains constant in the direction of gas flow. Furthermore, a spoiler assembly 20 is provided within the combustion channel 125. As the gas flows through the premixing channel 123 and the combustion channel 125, due to the inherent viscosity of the gas and the frictional resistance between the gas and the outer wall 310 of the cooking utensil 300, some of the gas tends to adhere to the outer wall 310 of the cooking utensil 300, forming a thick convection layer. However, the thermal conductivity of the gas is extremely low, so the heat generated by combustion cannot be quickly and efficiently transferred to the bottom of the cooking utensil 300 through the convection layer, resulting in insufficient heat conduction efficiency in the gas stove 1.

[0034] Based on the principle of continuous fluid flow, the flow rate into premixing channel 123 is equal to the flow rate out of premixing channel 123. In other words, the flow rate of gas through each opening of premixing channel 123 is also constant. According to the formula S1V1=S2V2, S1 represents the area of ​​the first flow section through which the gas flows, V1 represents the velocity of the gas flowing through the first flow section, S2 represents the area of ​​the second flow section through which the gas flows, and V2 represents the velocity of the gas flowing through the second flow section. In this application, the diameter of premixing channel 123 gradually decreases along the direction of gas flow. Therefore, as the gas flows within premixing channel 123, its velocity also gradually increases. This allows the gas flowing through premixing channel 123 to flow into combustion channel 125 at high speed. Furthermore, since the spoiler assembly 20 is housed in the combustion channel 125 and protrudes from the combustion surface 114, under the action of the spoiler assembly 20, the high-speed flowing gas is stirred and switched to a turbulent state. The speed direction of the gas in the turbulent state is diverse. Therefore, the gas can continuously impact the convection layer adhered to the outer wall surface 310 of the cooking utensil 300, so that the thickness of the convection layer becomes thinner, and then, the heat generated by the gas combustion can be transferred to the cooking utensil 300 faster and more, so that the gas stove 1 and its energy-gathering bracket 100 have higher heat conduction efficiency.

[0035] Understandably, in the present application, since the energy concentrator 10 has a good energy concentrating effect, the energy concentrating bracket 100 itself has a high heat conduction efficiency. Furthermore, due to the change in the diameter of the premixing channel 123 and the provision of the spoiler assembly 20, the energy concentrating bracket 100 has an even higher heat conduction efficiency.

[0036] The energy concentrator 10 also has a diverging surface 113, which is configured to form an expansion channel 124 with the outer wall 310 of the cooking vessel 300. The expansion channel 124 connects the premixing channel 123 and the combustion channel 125, and the diameter of the expansion channel 124 is larger than the diameter of the opening connecting the premixing channel 123 and the expansion channel 124. It will be understood that if the inner surface 111 also includes the diverging surface 113, and if the cooking vessel 300 is spaced apart from the inner surface 111, the expansion channel 124 is a closed annular channel, that is, it circumscribes the cooking vessel 300 along its circumference. If the cooking vessel 300 partially contacts the inner surface 111, the expansion channel 124 is a non-enclosed arcuate channel, that is, it extends along the circumference of the cooking vessel 300 but does not circumscribe the cooking vessel 300.

[0037] It can be understood that the premixing channel 123 is defined as having an input port and an output port. The gas injected by the burner 200 enters the premixing channel 123 from the input port and is output from the output port into the expansion channel 124. The diameter of the expansion channel 124 is larger than the diameter of the opening connecting the premixing channel 123 and the expansion channel 124. This means that the diameter of any opening in the expansion channel 124 is larger than the diameter of the output port. Because the diameter of the premixing channel 123 gradually decreases along the direction of gas flow, the resistance encountered by the gas also increases, leading to the risk of insufficient gas supply within the combustion channel 125. In the present application, by providing expansion channel 124, after the gas is accelerated through premixing channel 123 and flows into expansion channel 124, the gas encounters less resistance within expansion channel 124 because the diameter of expansion channel 124 is larger than the diameter of the outlet. Furthermore, expansion channel 124 connects premixing channel 123 and combustion channel 125. Thus, under the action of expansion channel 124, the gas can be adequately fed into combustion channel 125 for combustion and heat release. Understandably, due to inertia, in the direction of gas flow, provided the distance from expansion channel 124 is appropriate, the gas can still pass through expansion channel 124 at a relatively high velocity and flow into combustion channel 125.

[0038] Optionally, the diameter of the expansion channel 124 can remain constant or gradually decrease in the direction of gas flow. In one embodiment, the diameter of the expansion channel 124 gradually increases along the direction of gas flow. Therefore, as the gas flows through the expansion channel 124, its velocity gradually and slightly decreases. This minimizes the effect of the expansion channel 124 on the gas velocity, allowing the gas to still flow into the combustion channel 125 at a relatively high velocity and form turbulent combustion under the disturbance of the flow disturbance assembly 20.

[0039] Furthermore, the expansion channel 124 is in transitional communication with the premixing channel 123. Thus, when the gas flows into the combustion channel 125 through the expansion channel 124, the gas velocity loss is smaller, thereby enabling the gas to flow into the combustion channel 125 at a high speed.

[0040] Please also refer to Figure 3 The spoiler assembly 20 includes a plurality of spoilers 21, which are spaced apart along the circumference of the energy concentrator 10. The plurality of spoilers 21 spaced apart along the circumference of the energy concentrator 10 are also spaced apart along the circumference of the cooking appliance 300. The combustion channel 125 is also circumferentially disposed around the cooking appliance 300. Therefore, the plurality of spoilers 21 can fully disturb the gas flowing within the combustion channel 125 from the circumference of the cooking appliance 300, thereby increasing the turbulence intensity. This facilitates turbulent combustion of the gas within the combustion channel 125, and the gas can also effectively impact the convection layer, thereby improving the heat conduction efficiency of the energy concentrator support 100.

[0041] Optionally, each spoiler 21 can be in a block, plate, column or other shape. The multiple spoilers 21 in each spoiler assembly 20 can be arranged at intervals or continuously along the circumference. Optionally, the spoiler 21 and the energy concentrator 10 can be integrally formed or separately formed.

[0042] Furthermore, there are at least two flow-disturbing assemblies 20, all of which are spaced apart along the flow direction of the gas. Therefore, during the gas flow, the flow-disturbing assemblies 20 can fully disturb the gas, resulting in a greater turbulence intensity. As a result, the gas can effectively impact the convection layer, resulting in a higher heat conduction efficiency of the energy-concentrating support 100.

[0043] The energy concentrating bracket 100 also includes an inner insulation layer (not shown) and / or an outer insulation layer (not shown). The energy concentrating element 10 has an inner surface 111 including a premixing surface 112 and a combustion surface 114. The inner insulation layer covers the inner surface 111, and the outer insulation layer covers the outer surface 131 of the energy concentrating element 10 facing away from the inner surface 111. Optionally, the energy concentrating bracket 100 may include only the inner insulation layer, only the outer insulation layer, or both. The provision of the inner insulation layer and / or the outer insulation layer provides the energy concentrating element 10 with improved thermal insulation. Therefore, the heat generated by the combustion of the gas is less likely to dissipate to the outside and more slowly, thereby further improving the heat conduction efficiency of the energy concentrating bracket 100.

[0044] The energy concentrator 10 is provided with an air intake passage, which connects one of the premixing passage 123 and the combustion passage 125 to the outside world. Therefore, when the burner 200 is in operation, external secondary air can flow into the combustion passage 125 sequentially through the air intake passage and the premixing passage 123, or directly through the air intake passage and into the combustion passage 125, where it is thoroughly mixed with the combustion gas, allowing the combustion gas to be fully combusted. This reduces the carbon monoxide content generated, thereby achieving better environmental performance. Furthermore, due to the provision of the air intake passage, the combustion passage 125 and the premixing passage 123 can exchange heat with the outside world through the air intake passage, thereby reducing the temperature within the combustion passage 125 and the premixing passage 123, thereby preventing excessive temperatures within the combustion passage 125 and the premixing passage 123 from forming nitrogen oxides, further reducing environmental pollution. Furthermore, when the secondary air flows through the air intake channel, the secondary air is in contact with the inner wall of the air intake channel. Therefore, the secondary air can also absorb the heat of the energy-gathering member 10 and has a higher temperature. In this way, when the secondary air flows into the energy-gathering cavity 12, the heat generated by the combustion of the gas does not need to be used to heat the secondary air, or only a very small part of it needs to be used to heat the secondary air. The heat generated by the combustion can be concentrated on heating the cooking utensil 300, thereby having a higher heat conduction efficiency.

[0045] It's worth noting that the intake duct must be of a certain length to ensure that the secondary air can contact the inner wall of the intake duct and exchange heat with it as it flows through it. Furthermore, it should be noted that "air in gas" refers to the gas that mixes with the combustion gas before it exits the burner 200, while "secondary air" refers to the gas that mixes with the gas outside the burner 200.

[0046] Furthermore, it should be noted that during the combustion of the gas, the total amount of gas in the combustion channel 125 decreases, creating a negative pressure within the combustion channel 125 that is lower than the external atmospheric pressure. This allows secondary air to be drawn into the combustion channel 125 under the influence of the external atmospheric pressure. Furthermore, since the gas undergoes turbulent combustion within the combustion channel 125, this enhances the entrainment of the secondary air within the combustion channel 125, thereby accelerating the flow of external secondary air into the combustion channel 125 and ensuring sufficient combustion of the gas.

[0047] Optionally, the intake passage can communicate with the combustion passage 125 via the premixing passage 123, or can also communicate directly with the combustion passage 125. In one embodiment, the intake passage communicates between the exterior and the combustion passage 125. Therefore, during combustion, secondary air can enter the combustion passage 125 directly through the intake passage. The shorter path the secondary air takes leads to faster replenishment, allowing the secondary air to fully mix with the fuel gas and ensure sufficient combustion. Furthermore, the secondary air flowing into the combustion passage 125 can be disturbed by the spoiler assembly 20, further enhancing mixing of the secondary air and fuel gas.

[0048] Please refer again Figure 3 , and also see Figure 4 Furthermore, the energy concentrator 10 has a double-layer structure and includes an inner wall 11 and an outer wall 13. The inner wall 11 has an inner surface 111 including a premixing surface 112 and a combustion surface 114. The outer wall 13 is connected to the side of the inner wall 11 facing away from the inner surface 111, and is surrounded by the inner wall 11 to form a preheating chamber 126; an air inlet hole (not shown) is opened on the outer wall 13, and an air outlet hole 115 is opened on the inner wall 11. The air inlet hole, the preheating chamber 126 and the air outlet hole 115 are connected in sequence to form an air inlet channel. Compared to directly forming an air intake channel in a solid energy concentrator 10, since the secondary air flows from the air intake hole through the preheating chamber 126 and out the air outlet 115, and the air intake chamber is larger than the air intake hole, when the secondary air flows into the preheating chamber 126, it diffuses and contacts the walls of the preheating chamber 126. This results in a larger contact area and a relatively longer contact time between the secondary air and the walls of the preheating chamber 126, thus absorbing more heat. Consequently, the temperature of the secondary air flowing into the combustion channel 125 is also higher, thereby improving the heat conduction efficiency of the energy concentrator bracket 100. Specifically, it is understood that the outer wall 13 is provided on the side of the inner wall 11 facing away from the inner surface 111 thereof, and the surface of the outer wall 13 facing away from the inner wall 11 forms the aforementioned outer surface 131.

[0049] Optionally, there may be one or more air inlet channels. In one embodiment, multiple air inlet holes are provided on the outer wall 13, and an air outlet is provided on one side of each spoiler 21. Each air outlet provided on one side of each spoiler 21 corresponds one-to-one with an air inlet hole. The corresponding air inlet and outlet, together with the preheating chamber 126, form an air inlet channel. Thus, each spoiler 21 has a corresponding air inlet channel. During combustion, secondary air can enter the combustion chamber from multiple air inlet channels and be fully mixed with the fuel gas under the action of the spoiler 21.

[0050] Alternatively, the preheating chamber 126 can communicate with the outside only through the air inlet, or it can also communicate with the outside through another communication port 132. In one embodiment, a communication port 132 is further provided at one end of the energy concentrator 10 near the panel, communicating with the preheating chamber 126. The preheating chamber 126 communicates with the outside through the communication port 132, and this communication port 132 is different from the first mounting port 121 described above. This increases the number of paths for secondary air to flow into the energy concentrator chamber 12, facilitating sufficient combustion of the fuel gas.

[0051] In the aforementioned gas stove 1 and its energy-concentrating support 100, the diameter of the premixing channel 123 gradually decreases along the flow direction of the gas. When the gas flows through the premixing channel 123 while maintaining a constant flow rate, the gas velocity gradually increases, allowing the gas to flow into the combustion channel 125 at high speed. Furthermore, because the spoiler assembly 20 is housed within the combustion channel 125 and protrudes from the combustion surface 114, the high-speed gas flow is agitated and switched to a turbulent state under the action of the spoiler assembly 20. The turbulent gas continuously impacts the convection layer adhered to the outer wall 13 of the cooking vessel 300, thinning the convection layer, thereby enabling faster and more heat transfer to the cooking vessel 300. Thus, the gas stove 1 and its energy-concentrating support 100 of the present application have higher heat conduction efficiency.

[0052] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
