Description

Technical Field

[0001] This application relates to the field of cookware technology, and more particularly to a cookware capable of induction heating. Background Technology

[0002] Currently, there are various types of induction-heating cookware on the market. The principle of induction heating lies in electromagnetic technology. Through the action of an electromagnetic field, eddy currents are generated inside the cookware. These eddy currents circulate continuously inside the cookware, thereby generating heat and effectively heating the food inside the cookware. During the entire induction heating process, the cookware and the induction cooker must maintain close contact. Close contact promotes efficient heat conduction, ensuring a fast and even heating process and improving cooking efficiency.

[0003] However, existing induction-heating cookware has the following drawbacks: for example, after the induction cooker is turned off, the induction cooker panel retains a significant amount of heat, and the bottom of the cookware also retains preheating, which continues to heat the food, damaging its texture. During prolonged storage, the food is prone to spoilage due to continuous heating, affecting its edibility. The induction-heating cookware disclosed in this application effectively solves this problem through its unique structural design. When the food is heated, the cookware body is lifted, forming a gap with the surface of the induction cooker, reducing the continued conduction of heat and thus preventing the food from spoiling due to prolonged heating. This improves the control over the heating time of the food and brings users a more convenient and safer cooking experience. Utility Model Content

[0026] like Figure 1-4 The illustrated induction heating cookware includes a cookware body 1, a handle 2 fixedly connected to the outer side of the cookware body 1, a top elliptical ring 6 sleeved on the top outer side of the cookware body 1, two first telescopic posts 9 and a second telescopic post 19 fixedly connected to the two sides of the top elliptical ring 6, respectively, a left limiting block 8 and a right limiting block 18 fixedly connected to the top of the first telescopic posts 9 and 19, respectively, a main fixing frame 7 fixedly connected to the bottom of the two first telescopic posts 9, and a secondary fixing frame 1 fixedly connected to the bottom of the two second telescopic posts 19. 0. The bottom of the main fixing frame 7 and the auxiliary fixing frame 10 are fixedly connected to the bottom ring 3. The bottom ring 3 is fixedly connected to one side of the auxiliary fixing frame 10 with a screw 20. The front and rear sides of the top elliptical ring 6 are respectively fixedly sleeved with the main limiting plate 11 and the auxiliary limiting plate 13. The front and rear sides of the top elliptical ring 6 are respectively slidably connected with the main sliding tube 12 and the auxiliary sliding tube 14. The bottom of the main sliding tube 12 is spherically connected with the main support rod 5 and the pushing half ring 4. The bottom of the auxiliary sliding tube 14 is spherically connected with the auxiliary support rod 15 and the pushing half ring 4.

[0027] Furthermore, the bottom surface of the bottom ring 3 is flush with the bottom surface of the cookware body 1. The bottom end of the main support rod 5 is spherically connected to the bottom ring 3, and the bottom end of the auxiliary support rod 15 is spherically connected to the bottom ring 3. The connection points of the main support rod 5 and the auxiliary support rod 15 on the bottom ring 3 correspond to the main limiting plate 11 and the auxiliary limiting plate 13, respectively.

[0028] Furthermore, the main support rod 5 and the auxiliary support rod 15 are respectively inclined to the right and outward, and the main sliding tube 12 and the auxiliary sliding tube 14 slide along the front and rear sections of the top elliptical ring 6.

[0029] Furthermore, a sleeve 17 is fixedly connected to the middle of the push half-ring 4, a screw 20 is connected through the middle of the sleeve 17, and a nut 16 located outside the arc of the push half-ring 4 is threadedly connected to the middle of the screw 20.

[0030] Furthermore, the rotation of nut 16 pushes sleeve 17 to move along screw 20 toward the arc of push half ring 4, pushing the top of half ring 4 to move toward secondary limit plate 13 and main limit plate 11.

[0031] Furthermore, the first telescopic column 9 and the second telescopic column 19 are located on the outer side wall of the cookware body 1, and the left limiting block 8 and the right limiting block 18 are on the top of the outer edge of the cookware body 1.

[0032] Furthermore, the top elliptical ring 6 is elliptical in shape with the major axis of the main limiting plate 11 and the secondary limiting plate 13. The first telescopic post 9 and the second telescopic post 19 of the top elliptical ring 6 are in close contact with the outer side of the cookware body 1, and the main limiting plate 11 and the secondary limiting plate 13 of the top elliptical ring 6 are located on the outer side of the cookware body 1.

[0033] Furthermore, the bottom end of the pot handle 2 is located in the middle of the arc of the secondary fixing frame 10, the top elliptical ring 6 is located at the top of the bottom end of the pot handle 2, and the bottom circular ring 3 is located at the bottom of the bottom end of the pot handle 2.

[0034] Furthermore, the semi-ring 4 pushes the main sliding tube 12 and the auxiliary sliding tube 14 to slide along the top elliptical ring 6 toward the main limiting plate 11 and the auxiliary limiting plate 13, and the main sliding tube 12 and the auxiliary sliding tube 14 drive the top ends of the main support rod 5 and the auxiliary support rod 15 to move.

[0035] Furthermore, the tops of the main support rod 5 and the secondary support rod 15 are moved to the positions of the main limit plate 11 and the secondary limit plate 13, respectively, and then become vertical.

[0036] Working principle: When the induction cooker is powered on, its internal coil generates an alternating electromagnetic field. The cookware body 1 is placed in the electromagnetic field, which induces eddy currents inside the cookware body 1. As the eddy currents circulate inside the cookware body 1, the current overcomes the resistance of the cookware body to generate heat. This heat directly acts on the food inside the cookware. When the food is heated and continuous heating needs to be avoided, the nut 16 in the middle of the screw 20 is rotated. The nut 16 moves along the screw 11 towards the arc of the pushing half-ring 4, simultaneously pushing the sleeve 17, so that the pushing half-ring 4 gains thrust. Its two ends are respectively connected by a ball joint, driving the main sliding tube 12 and the auxiliary sliding tube 14 to slide along the front and rear sections of the top elliptical ring 6 towards the main limiting plate 11 and the auxiliary limiting plate 13. When sliding along the main sliding tube 12 and the auxiliary sliding tube 14, the main support rod 5 and the auxiliary sliding tube 14 are driven by the ball joint. The top of the support rod 15 moves synchronously towards the main limiting plate 11 and the secondary limiting plate 13. Since the bottom ends of the main support rod 5 and the secondary support rod 15 are fixed to the bottom ring 3 through a spherical connection, the tilt angle of the support rod gradually decreases during the movement of the top. When the main sliding tube 12 and the secondary sliding tube 14 slide to the position of the main limiting plate 11 and the secondary limiting plate 13, the main support rod 5 and the secondary support rod 15 become completely vertical, raising the top elliptical ring 6. The top elliptical ring 6 generates an upward supporting force on the pot body 1, raising the pot body 1 as a whole, so that the bottom of the pot forms a gap with the induction cooker panel, cutting off the conduction path of the residual heat of the induction cooker panel to the pot body. At the same time, the residual heat at the bottom of the pot is also reduced due to separation from the panel, thus avoiding the food from deteriorating in taste or spoiling due to continuous heating, and achieving precise control of the heating time of the food.

[0037] If reheating is required, rotate nut 16 in the opposite direction. Nut 16 moves away from the pushing half-ring 4, and the pushing half-ring 4 loses its thrust. At this time, the cookware body 1 can be gently pressed down. The main support rod 5 and the secondary support rod 15 return to their tilted state under the action of gravity, which drives the main sliding tube 12 and the secondary sliding tube 14 to reset along the top elliptical ring 6. The top elliptical ring 6 falls down, and the bottom ring 3 is flush with the bottom surface of the cookware body 1 again. The cookware body is then in contact with the induction cooker panel again.

[0038] By squeezing the top elliptical ring 6 at the ends of the main limiting plate 11 and the secondary limiting plate 13, the expansion of the top elliptical ring 6 on both sides pushes the telescopic column outward to adapt to cookware of different diameters and improve versatility. This solves the problem of "fixed size and poor adaptability" of traditional cookware accessories. The limiting blocks are structurally stable. The left limiting block 8 and the right limiting block 18 are fixed to the top of the telescopic column and located at the top of the outer edge of the cookware body 1. This can prevent the cookware from sliding outward during heating or movement, avoiding uneven heating or tipping risks caused by the displacement of the cookware. The bottom end of the handle 2 is located in the middle of the arc of the secondary fixing frame 10. The top elliptical ring 6 and the bottom ring 3 are located at the top and bottom of the bottom end of the handle 2, respectively, forming a surrounding support for the handle 2, further improving the stability of the overall structure of the cookware and preventing shaking when holding the handle 2.

Those skilled in the art should understand that this application is not limited to the above embodiments.
