The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0035] This embodiment discloses an energy-gathering pan rack and a gas stove including the energy-gathering pan rack, which are used to provide combustion heat for cooking. Figure 1 As shown, the gas stove also includes a burner 4, a burner 5 and a bottom shell 6. The burner 4 is arranged on the bottom shell 6, the burner 5 is arranged on the burner 4, the energy-gathering plate pot rack is arranged on the burner 4 and surrounds the outer periphery of the burner 5, and the cooking pots are placed on the energy-gathering plate pot rack and located above the burner 5. The burner 5 can heat the pots after ignition.

[0036] like Figure 1 and Figure 2 As shown, the energy-gathering pan stand includes an energy-gathering pan 1 and at least one set of movable flow-guiding mechanisms 2. The energy-gathering pan 1 includes an upper pan 11 and a lower pan 12. The upper pan 11 and the lower pan 12, when engaged, form a heat-insulating chamber 13. The side of the upper pan 11 near the center bulges outward to form an annular upper ridge 111. A heat-insulating groove 14 is formed between the upper ridge 111 and the outer edge of the upper pan 11. The heat-insulating groove 14 is located above the heat-insulating chamber 13.

[0037] All movable flow-guiding mechanisms 2 are evenly arranged along the circumference, and each group of movable flow-guiding mechanisms 2 includes movable flow-guiding members 21. The movable flow-guiding members 21 can extend into the heat-insulating groove 14 or retract into the heat-insulating cavity 13. The extension and retraction of the movable flow-guiding members 21 can be determined according to the shape of the pot bottom. Specifically, when the movable flow-guiding members 21 are located in the heat-insulating groove 14, the movable flow-guiding members 21 can disturb the high-temperature flue gas to extend its residence time. When disturbance of the high-temperature flue gas is not required, the movable flow-guiding members 21 retract into the heat-insulating cavity 13, and the movable flow-guiding members 21 will not affect the flow of the high-temperature flue gas.

[0038] The movable guide member 21 can be extended and retracted as needed to adapt to the use requirements of cookware with various bottom shapes, adapt to the energy gathering effect of different bottom shapes, improve the thermal efficiency of the gas stove, and do not affect the normal use of the energy gathering plate 1.

[0039] The specific structure of the mobile flow guide mechanism 2 is not limited, as long as it can drive the mobile flow guide member 21 to extend and retract. Figures 1 to 3As shown, each mobile deflector mechanism 2 further includes a driver 22, a telescopic rod 23, and a fixed plate 24. One end of the telescopic rod 23 is connected to the output shaft of the driver 22, and the other end is connected to the fixed plate 24. Each fixed plate 24 is provided with at least one mobile deflector 21. The mobile deflector 21 and the fixed plate 24 are capable of synchronous movement along the axis of the telescopic rod 23. The driver 22 can be, but is not limited to, a motor or a hydraulic cylinder, capable of driving the telescopic rod 23 to move the fixed plate 24 and the mobile deflector 21 upward and downward.

[0040] In order to avoid changing the structure of the existing energy-gathering disk 1 as much as possible, the fixed plate 24 is located in the insulation chamber 13, and the height of the insulation chamber 13 is the limit of the lifting distance of the fixed plate 24; a through hole is provided on the upper disk 11 for passing the movable flow guide 21, and the through hole is located at the bottom of the insulation groove 14, and the movable flow guide 21 can move along the axis of the through hole; a through hole is provided on the lower disk 12 for passing the telescopic rod 23, the fixed plate 24 is located in the insulation chamber 13, and the driving member 22 is located outside the insulation chamber 13. When the telescopic rod 23 moves along the axis of the through hole, the fixed plate 24 rises and falls in the insulation chamber 13, thereby driving the movable flow guide 21 to extend and retract. The structure is simple and reasonable, the driving method is easy to implement, and the movable flow guide 21 moves more smoothly.

[0041] The specific shape of the movable flow guide 21 is not limited, as long as it can disturb the flow of the high-temperature flue gas. In this embodiment, the cross-section of the movable flow guide 21, perpendicular to the axis of the energy-gathering disk 1, is a five-pointed star or petal shape. The outer peripheral surface of the movable flow guide 21 includes a protrusion and a depression. When the high-temperature flue gas flows toward the movable flow guide 21, it will collide with the depression and be blocked by the protrusion. This successfully changes the flow rate and flow path of the high-temperature flue gas, prolongs the heat exchange time between the high-temperature flue gas and the cookware, and fully recovers the heat in the high-temperature flue gas.

[0042] Building on the above structure, the energy-concentrating pan support further includes a control device and a sensor for detecting the shape of the pot bottom. The sensor's signal is connected to the control device. The sensor transmits the detected pot bottom shape information to the control device, which then controls the movable flow guide 21 to extend upward to different heights based on a preset correspondence, thereby adapting the flow-disturbing effect to pots with different bottom shapes.

[0043] In this embodiment, the control device can be a centralized or distributed controller. For example, the controller can be a single single-chip microcomputer or a distributed plurality of single-chip microcomputers. The control program can be run in the single-chip microcomputer to control the sensor and the drive element 22 to realize their functions.

[0044] like Figure 1 、 Figure 2 and Figure 4As shown, the energy-concentrating pan support also includes an auxiliary pan support 3, which is provided with at least one set of fixed flow guides 31 and at least three support members 32, on which the pot is placed. The fixed flow guides 31 protrude from the surface of the annular main body of the auxiliary pan support 3 and can disturb the high-temperature flue gas to extend its residence time, improve the utilization rate of the high-temperature flue gas heat, and enhance the thermal efficiency of the gas stove.

[0045] The specific installation structure of the auxiliary pot rack 3 is not limited. In this embodiment, a step surface is provided on the top of the upper plate 11, and the auxiliary pot rack 3 is installed on the step surface. The structure is more solid after installation; the step surface has a limiting effect, and the auxiliary pot rack 3 can be quickly and accurately set on the step surface, with high installation efficiency.

[0046] The specific shape of the fixed flow guides 31 is not limited, as long as it can disturb the high-temperature flue gas. In this embodiment, each set of fixed flow guides 31 includes two S-shaped guide blades 311. The S-shaped structure helps increase the width of the fixed flow guides 31 while minimizing the amount of material required. The high-temperature flue gas is blocked when it reaches the fixed flow guides 31, extending the heat exchange time between the high-temperature flue gas and the cookware and improving heat exchange efficiency.

[0047] like Figure 2 、 Figures 5 to 8 As shown, when the movable flow guide 21 is extended to its highest position, the top surface of the movable flow guide 21 is lower than the top surface of the fixed flow guide 31. The movable flow guide 21 and the fixed flow guide 31 form a two-layer flow disturbance structure, one high and one low. The high-temperature flue gas is disturbed when flowing through the movable flow guide 21 and the fixed flow guide 31, respectively, effectively recovering heat from the high-temperature flue gas.

[0048] Based on the above structure, the movable guide 21 and the fixed guide 31 are spaced apart along the circumference of the energy concentrating disk 1. The high-temperature flue gas is either blocked by the movable guide 21 or decelerated by the fixed guide 31, reducing the probability of the high-temperature flue gas flowing directly without passing through either the movable guide 21 or the fixed guide 31, and striving to reduce the speed of as much high-temperature flue gas as possible.

[0049] The energy-gathering plate pot stand selects corresponding working modes for different pot bottom shapes. Specifically, when using a pointed-bottom pot for cooking, there is a large space between the pointed-bottom pot and the energy-gathering plate 1 for high-temperature smoke to be discharged. The driving member 22 extends the movable guide member 21 into the heat-insulating groove 14 through the telescopic rod 23 and the fixed plate 24. When the high-temperature smoke flows through the heat-insulating groove 14, the movable guide member 21 can disturb the flow of the high-temperature smoke, extend the residence time of the high-temperature smoke, and improve the utilization rate of the heat in the high-temperature smoke. When the high-temperature smoke passes through the heat-insulating groove 14, the fixed guide member 31 can further disturb the high-temperature smoke, improve the heat exchange efficiency between the high-temperature smoke and the pot bottom, and improve the heat utilization rate.

[0050] When cooking with a frying pan, the space between the pan and the energy-concentrating plate 1 is relatively small, eliminating the need for the movable flow guide 21 to turbulently control the high-temperature flue gas within its inner ring. The driver 22 retracts the movable flow guide 21 via the telescopic rod 23 and fixed plate 24, retracting it at least partially into the heat-insulating chamber 13. The heat-insulating groove 14 significantly increases the residence time of the high-temperature flue gas, while the fixed flow guide 31 further turbulently controls the high-temperature flue gas, improving heat utilization and extending the heat exchange time between the high-temperature flue gas and the cookware.

[0051] Note that the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
