[0002] Gas stoves are one of the kitchen cooking appliances that are essential for daily family life. In order to pursue higher combustion thermal efficiency, some gas stoves use pot supports with energy-gathering plates, which are in the form of single-layer, double-layer or multi-layer. The use of pot supports with energy-gathering plates can separate the secondary air required for combustion from the high-temperature flue gas of combustion, so that the high-temperature flue gas of combustion is gathered in the energy-gathering plate, which enhances the heat energy exchange between the high-temperature flue gas and the bottom of the pot, reduces radiation and convection heat loss, and plays a role in gathering heat energy.

[0003] In the related technical field, since the pot rack cannot gather all the heat at the bottom of the cooker, smoke easily escapes from between the cooker and the pot rack, resulting in low overall thermal efficiency of the gas stove. Summary of the invention

Detailed implementation manners

[0026] In order to make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a gas stove 1. In the embodiment of the present application, the gas stove 1 includes a pot rack 10 and a burner 20. Among them, the pot rack 10 is used to be placed on a stove top (not shown in the figure) and is used to support cooking utensils, prevent the cooking utensils from sliding or tipping during the heating process, reduce the occurrence of accidental injuries, and ensure the stability of the cooking process.

[0028] The pot rack 10 surrounds the outside of the burner 20 and forms a combustion chamber 11a. In this way, the flame generated during the operation of the burner 20 will pass through the combustion chamber 11a to contact the bottom of the cooking utensil, realizing the heating of the cooking utensil. And under the surrounding of the pot rack 10, the heat of the burner 20 can be concentrated and transferred towards the bottom direction of the cooking utensil, blocking the heat from leaking out. Furthermore, the heat of the flame generated by the burner 20 can fully act on the cooking utensil to improve the thermal efficiency of the burner 20.

[0029] It can be understood that the pot rack 10 is a circular ring structure with a combustion chamber 11a provided at the center position. Of course, according to actual needs, the pot rack 10 can also be a square ring or other shapes; the combustion chamber 11a can also be a circular hole, a square hole, or other shaped holes. In the embodiment of the present application, no specific limitations are imposed on the overall shape of the pot rack 10 and the shape of the combustion chamber 11a.

[0030] In the related art, since the pot rack 10 cannot concentrate all the heat at the bottom of the cooking utensil, smoke is likely to escape between the cooking utensil and the pot rack 10, resulting in a low overall thermal efficiency of the gas stove 1.

[0031] Based on the above problems, please refer to Figures 1-3 , the pot rack 10 includes a pot rack body 11 and a power device 124.

[0032] The pot rack body 11 is arranged in a ring shape and encloses a combustion chamber 11a. The pot rack body 11 also has a jet channel 11c and an air supplement channel 11d.

[0033] The jet orifice 11c3 of the jet channel 11c is located on the upper surface 111a or the outer peripheral surface of the pot rack 10, and is used to provide an air flow in the direction close to the cooking utensil, so that the smoke between the pot rack body 11 and the cooking utensil can gather in the direction close to the cooking utensil, thereby increasing the contact time between the smoke and the bottom of the cooking utensil, facilitating more heat of the smoke to be conducted to the bottom of the cooking utensil, and further improving the thermal efficiency of the gas stove 1.

[0034] The air supplement orifice 11d3 of the air supplement channel 11d is communicated with the combustion chamber 11a, so as to be able to supplement secondary air to the combustion chamber 11a through the air supplement orifice 11d3, which can increase the air content in the combustion chamber 11a, thereby being able to provide additional oxygen for combustion, promoting more complete combustion of the fuel, and further improving the thermal efficiency of the fuel, so as to further improve the overall thermal efficiency of the gas stove 1.

[0035] And because the fuel can burn more completely, the generation of incomplete combustion products such as carbon monoxide and hydrocarbons can be reduced, so as to reduce the generation of residues such as unburned carbon particles (black smoke) and tar, reduce PM2.5 / PM10 emissions, and improve air quality. Further, because the generation of residues such as unburned carbon particles (black smoke) and tar can be reduced, the probability of residues clogging components such as the burner 20 and the flue can be reduced, the equipment maintenance cycle can be extended, the maintenance cost of users can be reduced, and the user experience can be improved.

[0036] The power device 124 is communicated with both the jet channel 11c and the air supplement channel 11d, and is used to provide an air flow to the jet channel 11c and the air supplement channel 11d. It can be understood that the power device 124 includes at least one of an air pump, a blower, and a jet generator 1242. In other embodiments, the power device 124 can also be in other forms. In the embodiments of the present application, the specific form of the power device 124 is not limited.

[0037] In the embodiment of the present application, the power device 124 provides airflows to the jet channel 11c and the air supplement channel 11d, and provides an airflow in the direction close to the cooking utensil through the jet orifice 11c3 of the jet channel 11c, so that the flue gas between the pot rack body 11 and the cooking utensil can gather in the direction close to the cooking utensil, thereby increasing the contact time between the flue gas and the bottom of the cooking utensil, facilitating more heat of the flue gas to be conducted to the bottom of the cooking utensil, and further improving the thermal efficiency of the gas stove 1; further, the air supplement orifice 11d3 of the air supplement channel 11d communicates with the combustion chamber 11a, so that secondary air can be supplemented to the combustion chamber 11a through the air supplement orifice 11d3, the air content in the combustion chamber 11a can be increased, thereby providing additional oxygen for combustion, promoting more complete combustion of the fuel, and further improving the thermal efficiency of the fuel to further enhance the overall thermal efficiency of the gas stove 1.

[0038] Please refer to Figures 1-3 , in an embodiment, the side of the pot rack body 11 facing away from the combustion chamber 11a is the outer side, and the central axis of the jet orifice 11c3 is inclined upward and outward from bottom to top, so that the airflow ejected from the jet orifice 11c3 can impact the flue gas between the pot rack body 11 and the cooking utensil at a specific angle. This inclined jetting method can guide the flue gas to spread fan-shaped upward and outward, thus more comprehensively and evenly covering the bottom of the cooking utensil, greatly increasing the contact area between the flue gas and the bottom of the cooking utensil, significantly improving the heat conduction efficiency, and further enhancing the thermal efficiency of the gas stove 1.

[0039] Please refer to Figures 1-3 , in an embodiment, the included angle between the central axis of the jet orifice 11c3 and the axis of the combustion chamber 11a is α, and α satisfies: 0≤α≤60°.

[0040] Please refer to Figure 3 , if α = 0°, at this time, the central axis of the jet orifice 11c3 is parallel to the axis of the combustion chamber 11a, and the airflow ejected from the jet orifice 11c3 impacts the bottom of the cooking utensil vertically, which can accurately act on the flue gas below the cooking utensil, promote the direct contact between the flue gas and the bottom of the cooking utensil, increase the contact time between the two, and improve the heat conduction efficiency. It is especially suitable for cooking utensils with a flat bottom and a diameter adapted to the combustion chamber 11a. The heat can be transferred to the cooking utensil evenly and quickly, reducing the loss of heat to the surrounding environment and enhancing the thermal efficiency of the gas stove 1.

[0041] And because the airflow ejected from the jet orifice 11c3 impacts the bottom of the cooking utensil vertically, the interference to the airflow inside the combustion chamber 11a is small, and the stability of the airflow in the combustion chamber 11a can be maintained. The stable airflow environment provides favorable conditions for the full combustion of the fuel, reduces the incomplete combustion phenomenon caused by airflow disorder, reduces the emission of pollutants such as carbon monoxide, and at the same time keeps the flame stable, ensuring the safety and efficiency of the cooking process.

[0042] If \(0^{\circ}<\alpha < 60^{\circ}\), as \(\alpha\) increases, the airflow ejected from the jet orifice 11c3 impacts the flue gas between the pot rack body 11 and the cooking utensil at an inclined angle, guiding the flue gas to spread outward in a fan shape, greatly increasing the contact area between the flue gas and the bottom of the cooking utensil, and further improving the thermal efficiency of the gas stove 1. In addition, the inclined jet forms a specific aerodynamic field above the combustion chamber 11a, driving the fresh air outside the combustion chamber 11a to be involved, mixing more fully with the high-temperature flue gas and fuel in the combustion chamber 11a, improving the combustion efficiency and reducing pollutant emissions.

[0043] And the above angle range can better adapt to cooking utensils of different shapes and sizes. For cooking utensils with a larger bottom or an arc shape, the inclined jet can ensure that the flue gas evenly covers the bottom of the cooking utensil, avoiding the phenomenon of uneven local heating.

[0044] Please refer to Figure 2 and Figure 3 In one embodiment, the pot rack body 11 includes an upper cover 111 and a lower cover 113. The upper cover 111 has an upper surface 111a; the lower cover 113 is connected to the upper cover 111 and forms an air supplement channel 11d and a jet channel 11c together with the upper cover 111, which can improve the forming convenience of the air supplement channel 11d and the jet channel 11c, and further improve the manufacturing efficiency of the pot rack body 11.

[0045] It can be understood that the upper surface 111a of the upper cover 111 has a jet orifice 11c3. In other embodiments, the outer sidewall of the lower cover 113 has a jet orifice 11c3. Of course, the jet orifice 11c3 can also be jointly defined by the outer edge of the upper cover 111 and the top edge of the lower cover 113. In the embodiments of the present application, the forming method of the jet orifice 11c3 is not specifically limited.

[0046] It can be understood that the lower cover 113 has an air supplement orifice 11d3. In other embodiments, the air supplement orifice 11d3 can also be jointly defined by the inner edge of the lower cover 113 and the inner edge of the upper cover 111. In the embodiments of the present application, the forming method of the air supplement orifice 11d3 is not specifically limited.

[0047] Please refer to Figure 2 and Figure 3 In one embodiment, the pot rack body 11 may further include a middle cover 112. The middle cover 112 is connected to the upper cover 111, and the lower cover 113 is connected to the middle cover 112. Of course, the lower cover 113 can also be connected to the upper cover 111.

[0048] Please refer to Figure 2 and Figure 3, in a specific embodiment, the air supplement channel 11d and the jet channel 11c can be formed by enclosing the upper layer cover 111 and the middle layer cover 112. At this time, the air supplement channel 11d and the jet channel 11c can be made closer to the combustion chamber 11a, so that the heat of the combustion chamber 11a can be transmitted to the air supplement channel 11d and the jet channel 11c through the upper layer cover 111, and then the air flow in the air supplement channel 11d and the jet channel 11c can be heated. On the one hand, it can make hot air enter the combustion chamber 11a through the air supplement port 11d3, reduce the energy required for the burner 20 to heat the air, accelerate the volatilization and combustion speed of the fuel, and improve the combustion efficiency of the fuel; on the other hand, after the air flow in the jet channel 11c is heated, it can carry more heat to impact the bottom of the cooking utensil, further improving the heat conduction efficiency, so as to further improve the thermal efficiency of the gas stove 1.

[0049] It can be understood that the upper surface 111a of the upper layer cover 111 has a jet port 11c3. In other embodiments, the outer side wall of the middle layer cover 112 has a jet port 11c3. Of course, the jet port 11c3 can also be jointly defined between the outer edge of the upper layer cover 111 and the top edge of the middle layer cover 112. In the embodiments of the present application, the forming method of the jet port 11c3 is not specifically limited.

[0050] It can be understood that the middle layer cover 112 has an air supplement port 11d3. In other embodiments, the air supplement port 11d3 can be jointly defined between the inner edge of the middle layer cover 112 and the inner edge of the upper layer cover 111. In the embodiments of the present application, the forming method of the air supplement port 11d3 is not specifically limited.

[0051] Please refer to Figure 2 and Figure 3 , in another specific embodiment, the air supplement channel 11d and the jet channel 11c are formed by enclosing the middle layer cover 112 and the lower layer cover 113. At this time, a heat preservation cavity is formed between the middle layer cover 112 and the upper layer cover 111, and the air flow in the air supplement channel 11d and the jet channel 11c can also be heated, so as to increase the temperature of the air flow blown out through the jet port 11c3 and the air supplement port 11d3, and further improve the thermal efficiency of the gas stove 1.

[0052] It can be understood that the outer side wall of the lower layer cover 113 has a jet port 11c3. In other embodiments, the jet port 11c3 can also be jointly defined between the outer edge of the middle layer cover 112 and the top edge of the lower layer cover 113. In the embodiments of the present application, the forming method of the jet port 11c3 is not specifically limited.

[0053] It is understandable that the lower cover 113 has an air supplement port 11d3. In other embodiments, the air supplement port 11d3 can also be defined jointly by the inner edge of the middle cover 112 and the inner edge of the lower cover 113. In the embodiments of the present application, the forming method of the air supplement port 11d3 is not specifically limited.

[0054] Please refer to Figure 2 and Figure 3 , in one embodiment, the lower cover 113 has an air inlet 113b communicating with the air supplement channel 11d and the jet channel 11c. The power device 124 is connected to the lower cover 113 and communicates with the air inlet 113b, and can accurately control the air flow rate entering the air supplement channel 11d and the jet channel 11c. By adjusting the power of the power device 124, the air supplement amount and the jet intensity can be flexibly adjusted according to different cooking requirements. For example, when stir-frying over high heat, increase the power of the power device 124 to provide sufficient secondary air for the combustion chamber 11a, and at the same time enhance the jet intensity to quickly guide the flue gas to gather at the bottom of the cooking utensil, improving the heat conduction efficiency; when simmering over low heat, reduce the power of the power device 124 to maintain a stable combustion state and avoid energy waste.

[0055] Please refer to Figure 2 and Figure 3 , in one embodiment, the length of the jet channel 11c is longer than the length of the air supplement channel 11d, so that the jet air flow has a longer path in the jet channel 11c to absorb the waste heat of the combustion chamber 11a. Therefore, when the jet air flow impacts the bottom of the cooking utensil, it can carry more heat, greatly increasing the contact time and area between the flue gas and the bottom of the cooking utensil, so as to significantly improve the thermal efficiency of the gas stove 1.

[0056] And because the lengths of the jet channel 11c and the air supplement channel 11d are different, it helps to realize the differential regulation of the jet and the air supplement air flows. The longer jet channel 11c can slow down the flow rate of the jet air flow and make it act on the cooking utensil in a more stable state; the shorter air supplement channel 11d can ensure that the secondary air quickly enters the combustion chamber 11a, mixes with the fuel in time, promotes full combustion, and realizes the coordinated optimization of the heat transfer and combustion processes.

[0057] Please refer to Figure 3 , specifically, the jet channel 11c can include a first inclined section 11c1 and a vertical section 11c2. The first inclined section 11c1 is inclined and extends outward from bottom to top; one end of the first inclined section 11c1 communicates with the air inlet 113b, the other end of the first inclined section 11c1 communicates with one end of the vertical section 11c2, and the other end of the vertical section 11c2 is the jet port 11c3. In other embodiments, the jet channel 11c may also have other composition forms. In the embodiments of the present application, the specific form of the jet channel 11c is not limited.

[0058] The air supply channel 11d includes a second inclined section 11d1 and a horizontal section 11d2. The second inclined section 11d1 is inclined inward from bottom to top. One end of the second inclined section 11d1 is connected to the air inlet 113b, and the other end of the second inclined section 11d1 is connected to one end of the horizontal section 11d2. The other end of the horizontal section 11d2 is the air supply port 11d3. In other embodiments, the jet channel 11c may also have other composition forms. In the embodiment of the present application, the specific form of the jet channel 11c is not limited.

[0059] Please refer to Figures 2-4 In one embodiment, the pot rack 10 further includes a plurality of air-supplementing cyclone members 1234, which are arranged at intervals in the air-supplementing channel 11d, and an air-supplementing cyclone channel 123d is formed between two adjacent air-supplementing cyclone members 1234. The air-supplementing cyclone channel 123d is used to change the flow direction of the secondary air in the air-supplementing channel 11d, so that the secondary air blown out from the air-supplementing port 11d3 surrounds the axial arrangement of the combustion chamber 11a, ensuring that the fuel is fully in contact with the air and mixed evenly, thereby ensuring that the fuel is fully burned, so as to improve the thermal efficiency of the fuel, and thereby improve the overall thermal efficiency of the gas stove 1.

[0060] Specifically, the air-supplementing cyclone member 1234 may include an arc-shaped cyclone plate (not shown in the figure), which extends in an arc shape, so that the air-supplementing cyclone channel 123d is arc-shaped, so as to extend the movement path of the air, and further extend the contact time between the air and the air around the combustion chamber 11a, so as to increase the preset temperature of the air around the combustion chamber 11a, and further improve the overall thermal efficiency of the gas stove 1.

[0061] It is understandable that the air supplement cyclone element 1234 may also include a plane cyclone plate (not shown in the figure), which is arranged at an angle with the radial direction of the combustion chamber 11a passing through it, and can also change the flow direction of the air, so that the air blown out from the air supplement port 11d3 can be arranged around the axial direction of the combustion chamber 11a to extend the movement path of the air, thereby increasing the preset temperature of the air in the combustion chamber 11a, and thereby increasing the overall thermal efficiency of the gas stove 1. In the embodiment of the present application, the specific form of the air supplement cyclone element 1234 is not limited.

[0062] In one embodiment, the pot stand 10 further includes a plurality of jet swirl members (not shown in the figures). The plurality of jet swirl members are spaced apart and disposed in the jet channel 11c. A jet swirl channel is formed between two adjacent jet swirl members. The jet swirl channel is configured to change the flow direction of the jet air flow within the jet channel 11c, such that the jet air flow blown out from the jet orifice 11c3 is arranged around the axis of the combustion chamber 11a, capable of forming a spiral upward air flow around the bottom of the cooking utensil. This spiral air flow can increase the contact area between the flue gas and the bottom of the cooking utensil, and can also extend the contact time between the flue gas and the cooking utensil, thereby ensuring that more heat can be transferred to the cooking utensil to significantly improve the heat conduction efficiency.

[0063] Moreover, the jet air flow around the axis of the combustion chamber 11a drives the flue gas around the bottom of the cooking utensil to form a uniform rotating flow field, capable of avoiding heat concentration in a local area, preventing uneven heating of the cooking utensil, and improving the cooking quality.

[0064] It can be understood that the jet swirl members may also include arc-shaped swirl members and planar swirl members, which will not be elaborated here. In other embodiments, the jet swirl members may also be in other forms. In the embodiments of the present application, the specific form of the jet swirl members is not limited.

[0065] Please refer to Figure 2 and Figure 3 , in one embodiment, the pot stand 10 further includes a lower support leg 114. The lower support leg 114 is connected to the pot stand body 11, capable of ensuring that the pot stand 10 maintains a fixed position during operation, making the jet and air supplement effects more stable and effective.
