[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses an energy-concentrating pot rack.

[0027] Reference Figure 1 A pot-shaped energy-concentrating frame includes a fixed energy-concentrating ring 1 and a movable energy-concentrating ring 2. The movable energy-concentrating ring 2 is arranged circumferentially along the fixed energy-concentrating ring 1 and is located within or outside the fixed energy-concentrating ring 1. At least a portion of the tops of the fixed energy-concentrating ring 1 and the movable energy-concentrating ring 2 have a height difference in the height direction of the pot-shaped energy-concentrating frame. When the fixed energy-concentrating ring 1 is located within the inner ring relative to the movable energy-concentrating ring 2, the top height of the movable energy-concentrating ring 2 is higher than the top height of the fixed energy-concentrating ring 1. When the fixed energy-concentrating ring 1 is located within the outer ring relative to the movable energy-concentrating ring 2, the top height of the movable energy-concentrating ring 2 is lower than the top height of the fixed energy-concentrating ring 1.

[0028] In this embodiment, the movable energy-concentrating ring 2 is located around the fixed energy-concentrating ring 1. The fixed energy-concentrating ring 1 is formed with a support portion 100 for abutting against the bottom of the pot. At least a portion of the height of the movable energy-concentrating ring 2 is higher than the height of the support portion 100.

[0029] Reference Figure 2 and Figure 3 The fixed energy-concentrating ring 1 includes a fixed energy-concentrating plate 11 and multiple pot rack corner pieces 13 connected to the fixed energy-concentrating plate 11. The top of the fixed energy-concentrating plate 11 is open, and the bottom of the fixed energy-concentrating plate 11 has a bottom surface. A central hole 10 for accommodating the stove burner head is provided in the center of the bottom surface. The inner diameter of the top opening of the fixed energy-concentrating plate 11 is larger than the inner diameter of the central hole 10.

[0030] The pot rack corner pieces 13 are at least three in number and distributed around the circumference of the fixed energy-concentrating plate 11. Each pot rack corner piece 13 includes a top corner piece 131 that is horizontal and extends radially along the fixed energy-concentrating plate 11, and a bottom corner piece 132 connected below the top corner piece 131. The top corner piece 131 is elongated, with one end located within the inner circle of the fixed energy-concentrating plate 11, and the other end extending away from the center of the fixed energy-concentrating plate 11 beyond its edge. The top end of the top corner piece 131 near the center of the fixed energy-concentrating plate 11 has a chamfered angle. The bottom corner piece 132 is integrally formed from the bottom of the top corner piece 131 and extends downwards, protruding from the bottom surface of the fixed energy-concentrating plate 11, allowing the bottom corner piece 132 to be stably supported on the cooktop surface. In other embodiments, the structure and shape of the pot rack corner pieces 13 can be modified; the pot rack corner pieces 13 can be welded to the fixed energy-concentrating plate 11 or integrally formed with it.

[0031] The top of the pot rack corner piece 13 is higher than the top of the fixed energy-concentrating plate 11, and the top of the pot rack corner piece 13 serves as a support part 100 for abutting against the bottom of the pot.

[0032] Reference Figure 2 and Figure 4 The movable energy-concentrating ring 2 includes a movable energy-concentrating disk 21 and a movable positioning part 22 connected to the movable energy-concentrating disk 21. The movable energy-concentrating disk 21 is cylindrical and has a thin-walled structure. Both the fixed energy-concentrating ring 1 and the movable energy-concentrating ring 2 can be made of metal materials with a temperature resistance greater than 700°C, with stainless steel being preferred. In other embodiments, the structural shape of the movable energy-concentrating disk 21 can also be changed according to the structural shape of the fixed energy-concentrating disk 11, and the sidewall of the movable energy-concentrating disk 21 can have a certain tilt angle.

[0033] The top of the inner peripheral wall of the active energy-concentrating disk 21 has an inclined chamfer.

[0034] The number of movable positioning parts 22 is the same as the number of pot frame corner pieces 13, and they are arranged in a one-to-one correspondence. The movable positioning part 22 includes a movable positioning piece 221, which is arranged radially along the movable energy concentrating plate 21 and connected to the outer peripheral wall of the movable energy concentrating plate 21. The movable positioning piece 221 is arranged horizontally.

[0035] In order to fit the movable energy-concentrating ring 2 onto the outer periphery of the fixed energy-concentrating ring 1 from top to bottom, each movable positioning piece 221 is provided with a positioning groove 20 extending radially along the movable energy-concentrating disk 21. The positioning groove 20 first extends radially along the movable energy-concentrating disk 21 and passes through the side of the movable positioning piece 221 near the center of the movable energy-concentrating disk 21, and then extends vertically along the peripheral wall of the movable energy-concentrating disk 21 to the bottom of the movable energy-concentrating disk 21. Each positioning groove 20 corresponds to a pot rack corner piece 13.

[0036] The movable energy-concentrating ring 2 inserts the positioning groove 20 into the pot frame corner piece 13 from top to bottom, and positions the movable energy-concentrating disk 21 on the outer periphery of the fixed energy-concentrating disk 11. In other embodiments, the movable energy-concentrating disk 21 may also be located on the inner periphery of the fixed energy-concentrating disk 11.

[0037] In one embodiment, the movable energy-concentrating ring 2 and the fixed energy-concentrating ring 1 are both independently provided. When a flat-bottomed pan is needed, the movable energy-concentrating ring 2 is removed from the energy-concentrating pan rack, and the fixed energy-concentrating ring 1 is used alone, ensuring that the bottom of the flat-bottomed pan rests against the support portion 100 formed by the pan rack corner piece 13. When a pointed-bottomed pan is needed, the positioning groove 20 on the movable energy-concentrating ring 2 is aligned with each pan rack corner piece 13, and it is inserted from top to bottom into the outer periphery of the fixed energy-concentrating ring 1, so that the bottom of the movable energy-concentrating ring 2 can be supported on the stovetop. At this time, the top of the inner peripheral wall of the movable energy-concentrating plate 21 is close to the bottom of the pan, and the height of the top of the inner peripheral wall of the movable energy-concentrating plate 21 is higher than the top height of the support portion 100. This allows the movable energy-concentrating plate 21 to be closer to the upper part of the pointed-bottomed pan, reducing the gap between the top of the energy-concentrating pan rack and the bottom of the pointed-bottomed pan, improving thermal efficiency, and achieving better energy-saving effects.

[0038] Reference Figures 2-4 In this embodiment, in order to enable the movable energy-concentrating ring 2 to adapt to different types of cookware, an elastic element 3 is provided between a part of the movable energy-concentrating ring 2 and a part of the fixed energy-concentrating ring 1. The elastic element 3 enables the movable energy-concentrating ring 2 to abut or approach the bottom of the cookware in the height direction of the energy-concentrating pot rack.

[0039] To enable the movable energy-concentrating ring 2 to extend and retract along the height direction of the energy-concentrating pot frame, the fixed energy-concentrating ring 1 also includes a base positioning part 12. One of the movable positioning part 22 and the base positioning part 12 is provided with a positioning post 41, and the other is provided with a guide hole 42 for inserting the positioning post 41. The positioning post 41 and the guide hole 42 are coaxially arranged and both are arranged along the height direction of the energy-concentrating pot frame.

[0040] In this embodiment, the positioning post 41 is connected to the movable positioning part 22, and the base positioning part 12 includes a guide post 420, and a guide hole 42 is disposed on the guide post 420.

[0041] To facilitate the installation of the positioning post 41, each movable positioning piece 221 has a horizontally extending movable positioning support piece 2211. The movable positioning support piece 2211 has a fixing hole 2210 through which the positioning post 41 passes. A portion of the positioning post 41 extends downwards along the height direction of the energy-concentrating pot frame, while another portion extends upwards along the height direction of the energy-concentrating pot frame to form a top rod 410. The outer peripheral wall of the positioning post 41 is integrally formed with a disc-shaped positioning platform 411. The top surface of the positioning platform 411 abuts against the bottom surface of the movable positioning support piece 2211. The portion of the positioning post 41 located above the positioning platform 411 is defined as the top rod 410. The top rod 410 extends out of the fixing hole 2210 and has an external thread on its outer peripheral wall near the positioning platform 411. A fixing nut is threaded onto this thread, and the fixing nut can be tightened against the top surface of the movable positioning support piece 2211, thereby fixing the positioning post 41 onto the movable positioning support piece 2211.

[0042] The top rod 410 is located on the outer periphery of the movable energy-concentrating plate 21, and the highest height of the top rod 410 is higher than that of the support part 100.

[0043] In order to connect the guide post 420, the base positioning part 12 also includes a base positioning piece 121, and the guide post 420 is detachably connected to the base positioning piece 121.

[0044] The base positioning piece 121 is horizontal and integrally formed on the vertical sidewall of the bottom corner piece 132. A connecting hole is provided on the base positioning piece 121. A connecting platform 4201 with a diameter larger than the connecting hole is provided at the bottom end of the guide post 420. The top surface of the connecting platform 4201 abuts against the bottom surface of the base positioning piece 121. An external thread is provided on the outer wall of the guide post 420 near the connecting platform 4201. This external thread allows a portion of the guide post 420 to pass through the connecting hole and be threaded into it. Alternatively, a locking nut that can be tightened against the top surface of the base positioning piece 121 can be threaded into this external thread. A guide hole 42 is provided on the top surface of the portion of the guide post 420 extending beyond the connecting hole. The guide hole 42 extends along the height direction of the energy-concentrating pot frame and is coaxially arranged with the corresponding positioning post 41. The positioning post 41 can be inserted into the guide hole 42, and the positioning post 41 and the guide hole 42 can be configured as a clearance fit.

[0045] In this embodiment, the elastic element 3 is a telescopic spring. The portion of the positioning post 41 located below the movable positioning support 2211 passes through the elastic element 3 and extends into the guide hole 42. One end of the elastic element 3 abuts against the movable positioning part 22, and the other end abuts against the base positioning part 12. In this embodiment, a portion of the elastic element 3 is sleeved on the guide post 420, and the top end of the elastic element 3 abuts against the bottom surface of the positioning platform 411, while the bottom end of the elastic element 3 abuts against the top surface of the locking nut outside the guide post 420. Thus, by utilizing the elastic element 3, an elastic force can be applied to the entire movable energy-concentrating ring 2, allowing the movable energy-concentrating ring 2 to be adjusted to different heights within a certain height range.

[0046] Reference Figure 5 and Figure 6 In its natural state, the top of the inner circumferential wall of the movable energy-concentrating plate 21 is higher than the highest height of the pot rack corner piece 13. When a pointed-bottom pot is needed, the movable energy-concentrating ring 2, under the elastic force of the elastic element 3, brings the top of the inner ring of the movable energy-concentrating plate 21 close to or against the bottom of the pointed-bottom pot, thereby reducing the gap between the bottom of the pointed-bottom pot and the top of the energy-concentrating pot rack, achieving a more energy-saving effect. When a flat-bottom pot is needed, the bottom of the flat-bottom pot will abut against the top of the top rod 410, and apply downward pressure to the top rod 410. Under the elastic action of the elastic element 3, the movable energy-concentrating plate 21 can move downward until the bottom of the pot abuts against the top of the pot rack corner piece 13. Because the top height of the top rod 410 is higher than the top of the inner circumferential side of the movable energy-concentrating plate 21, a gap for normal smoke exhaust can be formed between the top of the movable energy-concentrating plate 21 and the bottom of the pot.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
