Description

Technical Field

[0001] This invention relates to a cooktop, and more particularly to a pot rack, specifically a self-adjusting and universal heat-concentrating pot rack. Background Technology

[0002] As we all know, pot supports are essential components of stovetops. They not only support the bottom of the pot, but also, to achieve energy savings and improve thermal efficiency, most stove manufacturers have incorporated heat-concentrating structures into the pot support design. This is achieved by incorporating a solid, arc-shaped reflective surface on the inner side of the pot support. This reflects the heat generated by the burner back to the bottom of the pot, reducing heat loss and improving thermal efficiency, resulting in significant energy savings. However, since the size of the pot support is fixed, it must be paired with pots of a specific size to achieve optimal heat concentration. Since pots come in various sizes, the fixed reflective surface of the pot support cannot achieve optimal heat concentration when placed on it. Therefore, if the reflective surface of the pot support could automatically adapt to the size of the pot, it would achieve the best heat concentration effect. Currently, there is no good solution for this. Summary of the Invention

[0003] The purpose of this invention is to address the problem that the reaction surface of existing pot racks cannot be adaptively adjusted according to the size of the pot, and to design a variable universal heat-concentrating pot rack that can automatically adjust the angle of the reflective surface according to the size and weight of the pot to achieve optimal matching.

[0004] The technical solution of this invention is:

[0005] A self-adjustable universal heat-concentrating pot support includes a pot support body 9, characterized in that: multiple sets of fixing feet 10 are installed on the pot support body 9, each set of fixing feet 10 is provided with a rotating shaft fixing hole 11, and a pot bottom support piece 1 is fitted on each set of fixing feet 10, with several pot bottom support pieces 1 surrounding and covering the inner surface of the pot support body 9; a pot bottom support 2 is fixed on the arc-shaped bottom plate 4 with heat-concentrating function of each pot bottom support piece 1, which is in contact with the bottom of the pot, and a through hole 17 for a rotating shaft 8 is provided on the pot bottom support 2. The rotating shaft 8 is installed in the rotating shaft fixing hole 11 and the through hole 17, so that the inner force foot 5 or the outer force angle 6 of the pot bottom support 2 is subjected to the weight of the pot, forcing the pot bottom support 2 to drive the arc-shaped bottom plate 4 to rotate around the rotating shaft 8, thereby realizing the adaptive adjustment of the heat-concentrating and reflecting angle of the arc-shaped bottom plate 4.

[0006] Each set of fixing feet 10 consists of two triangular pieces with the same structure, and the upper part of the triangular pieces is provided with a rotating shaft fixing hole 11.

[0007] The pot bottom support plate 1 is provided with insertion holes 3 for inserting fixing feet 10.

[0008] The number of fixed feet 10 is four sets, and the number of pot bottom support pieces 1 is also four. The total arc length of the inner or outer arc of the four pot bottom support pieces 1 is greater than the total arc length of the corresponding inner or outer arc of the pot support body 9. During installation, the four pot bottom support pieces 1 overlap and surround the inner arc surface of the pot support body 9.

[0009] The beneficial effects of this invention are:

[0010] This invention achieves adaptive adjustment of the heat-concentrating reflective surface, which can be adaptively adjusted according to the size and weight of the cookware. When the size of the cookware is not optimal, the reflective surface 4 can be adjusted by its own weight or by the user applying external pressure to adapt to the change in the size of the cookware.

[0011] This invention has a simple and ingenious structure, and is easy to install, manufacture, and adjust.

[0012] This invention has a good heat-concentrating effect, can achieve convenient energy saving, and is suitable for energy-saving use of cookware of all sizes. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-5 As shown.

[0020] A self-adjustable universal heat-concentrating pot frame includes a pot support body 9, on which four sets (three or five sets or more in specific implementations) of fixing feet 10 are installed. Figure 4 As shown, each set of fixing feet 10 consists of two identical triangular pieces. The upper part of the triangular pieces has a rotating shaft fixing hole 11. Each set of fixing feet 10 is fitted with a... Figure 1 The pot bottom support piece 1 shown has insertion holes 3 for inserting fixing feet 10. Four pot bottom support pieces 1 are assembled into a single unit. Figure 2The structure shown covers the inner surface of the pot support body 9. To prevent gaps from forming between adjacent pot bottom support pieces 1 due to processing and assembly, the total arc length of the inner or outer arc of the four pot bottom support pieces 1 is greater than the total arc length of the corresponding inner or outer arc of the pot support body 9. During installation, the four pot bottom support pieces 1 overlap and surround the inner arc surface of the pot support body 9, as shown. Figure 3 As shown by the dashed line. A pot bottom support 2, which contacts the pot bottom, is fixed on the arc-shaped bottom plate 4 of each pot bottom support piece 1, which has a heat-concentrating function. The pot bottom support 2 has a through hole 17 for mounting a rotating shaft 8. The rotating shaft 8 ( Figure 3 The bottom support 2 is inserted into the rotating shaft fixing hole 11 and through hole 17, so that the inner force-bearing foot 5 or the outer force-bearing angle 6 of the pot bottom support 2 is subjected to the weight of the pot, which forces the bottom support 2 to drive the arc-shaped bottom plate 4 to rotate around the rotating shaft 8, realizing the adaptive adjustment of the heat-reflecting angle of the arc-shaped bottom plate 4. The rotating shaft 8 can be a single-ended screw or a double-ended screw, and a nut is screwed on the threaded end of the screw to prevent it from falling out of the hole through which it is inserted.

[0021] Details are as follows:

[0022] A self-adjustable universal heat-concentrating pot frame includes: a pot bottom support plate 1, a pot bottom support 2, an insertion hole (pre-reserved square hole) 3, an arc-shaped bottom plate (circular arc surface) 4, inner force-bearing feet 5, outer force-bearing angles 6, lower fixing angles 7 (fixing feet at both ends), a rotating shaft 8, a pot frame body 9, fixing feet 10, a rotating shaft fixing hole (for positioning) 11, and an assembled finished product 12. Figure 5 ).

[0023] Four identical independent pot bottom support pieces 1 are provided, each with a welded pot bottom support 2. Each pot bottom support 2 has pre-drilled square holes 3 on both sides, and the length of these holes 3 is greater than the maximum width of the triangular pot support fixing feet 10 on the main body 9 of the pot support. The pot support fixing feet 10 are triangular (or trapezoidal) to limit the rotational amplitude of the pot bottom support pieces 1. The total arc length of each independent pot bottom support piece 1 is greater than one-quarter of the circle forming the circular arc surface 4, ensuring that the four independent pot bottom support pieces 1 are without gaps during rotation. The pot bottom support piece 1 is an arc-shaped surface 4, with the rotating shaft fixing hole 11 as the center. The distance from the hole to the inner force foot 5, the outer force angle 6, and the lower fixing angle 7 (the two end fixing feet) is equal, ensuring that the arc surface 4 of the pot bottom support piece 1 does not shift during rotation. The vertical distance from the outer force angle 6 to the arc surface 4 is fixed at one centimeter, ensuring that the distance between the pot bottom and the upper edge of the pot bottom support piece 1 remains one centimeter regardless of the size of the pot or the size of the opening, thus guaranteeing the heat-concentrating effect of the enclosed pot. The rotating shaft fixing hole (for positioning) 11 on the pot bottom support piece 10 is a through hole and a tapped hole (it can also be a through hole, but the length of the rotating shaft 8 should be slightly longer than the distance between the two fixing feet 10 plus the thickness of the feet, so as to facilitate the installation of a nut at the threaded end). This ensures that the rotating shaft 8 passes through the through hole 17, and the pot bottom support piece 1 can rotate flexibly after fixing. The arc surface of the pot support body 9 is an arc surface concentric with the pot bottom support piece 1. The lower inner diameter opening of the pot support body 9 can remain unchanged during the rotation of the pot bottom support piece 1.

[0024] Installation instructions: When installing the pot bottom support piece 1 on the main body 9 of the pot support, install them symmetrically, and then install the next symmetrical pot bottom support piece 1 to ensure that they do not interfere with each other when rotating during use.

[0025] The working principle of this invention is:

[0026] When there is no pot, the pot bottom support piece 1 remains open due to gravity. Its opening is limited by the edge 15 of the pot support fixing foot 10 and the edge 16 of the pre-drilled square hole 3. To prevent the pot from being too small and its bottom from contacting the burner core, thus affecting normal combustion, its maximum limit when placing the pot is formed by the edge 13 of the pot support fixing foot 10 and the edge 14 of the pre-drilled square hole 3. Figure 5 As shown. When placing the pot during operation, the bottom of the pot first contacts the inner support foot 5. The weight of the pot is then pressed down by the inner support foot 5 until the outer support angle 6 contacts the bottom of the pot. This forms an enclosed heat-concentrating pot frame, achieving optimal heat concentration regardless of the pot's position.

[0027] All parts not covered in this invention are the same as or can be implemented using existing technologies.
