Description

Technical Field

[0001] This utility model relates to the field of stove accessories technology, and in particular to a stove frame with a multi-cavity heat insulation and energy-concentrating structure. Background Technology

[0002] As a key component of gas stoves, the burner rack's primary function is to support cooking utensils. To improve the thermal efficiency of gas stoves, both household and commercial gas stoves commonly employ metal burner racks with energy-concentrating functions. These burner racks are typically designed with a double-layer structure, where the upper support surface and the lower base are sealed together by welding or other methods, forming an air-filled cavity. The core principle lies in utilizing air's poor thermal conductivity; the cavity's insulation reduces heat loss to the burner rack and the area beneath the stove during combustion, thus achieving a certain level of energy saving. However, existing energy-concentrating burner racks still have significant shortcomings:

[0003] 1. Limited energy-concentrating effect and insignificant improvement in thermal efficiency: Its energy-saving mechanism mainly relies on the passive insulation of the cavity air, which cannot more effectively concentrate and utilize the heat of the flame. The improvement in the thermal efficiency of gas combustion is limited, and there is still considerable room for improvement in energy-concentrating effect.

[0004] 2. Difficult cleaning and maintenance, resulting in a poor user experience: The cooktop rack is typically a one-piece welded bowl or plate-shaped structure. During cooking, dripping oil, soup, and other contaminants easily flow and accumulate on the rack's surface. Cleaning requires removing the heavy rack from the cooktop and wiping or rinsing the entire surface. This is cumbersome, involves cleaning a large area, is inefficient, and the frequent disassembly of heavy parts increases the user's burden.

[0005] Further improvements are needed. Utility Model Content

[0008] The lower bowl base has an annular groove structure with an opening at the top; the upper cover plate has an annular cover plate structure, which is detachably mounted on the lower bowl base and forms a heat-insulating cavity with the lower bowl base.

[0009] The lower bowl seat is provided with an annular overlapping platform; the energy-concentrating partition is placed on the overlapping platform and separates the upper and lower sides of the heat-insulating cavity.

[0010] Optionally, the energy-concentrating partition is provided with an annular mound-like structure with arched protrusions.

[0011] Optionally, the annular mound structure may have multiple mounds of different diameters arranged at the same center.

[0012] Optionally, the outer edge of the energy-concentrating partition is provided with an outwardly extending overlapping edge plate, which overlaps the overlapping platform.

[0013] Optionally, the overlapping platform is provided with several layers along the vertical direction for arranging multiple energy-concentrating partitions at vertical intervals.

[0014] Optionally, the outer edge of the lower bowl base is provided with an upwardly extending outer ring wall, and a horizontally extending outer edge is provided above the outer ring wall; the outer edge of the upper cover plate is provided with an outwardly turned edge; the outwardly turned edge can be fitted onto the outer edge.

[0016] Optionally, the lower bowl base is provided with several leg structures on its lower side; the upper cover plate is provided with several supporting ears.

[0017] The beneficial effects of this invention are as follows: By adding an energy-concentrating baffle within the main heat-insulating cavity formed by the lower bowl and the upper cover, a single cavity is divided into two or more independent air chambers. This multi-cavity heat insulation structure effectively increases the number of heat-barrier layers, forming a multi-level heat insulation barrier. Cleaning and maintenance are convenient and efficient, significantly improving the user experience. The detachable design of the upper cover and lower bowl is key to solving cleaning problems. When cooking oil or soup drips, simply remove the upper cover for cleaning.

[0031] The lower bowl base 10 has an annular groove structure with an opening at the top; the upper cover plate 20 has an annular cover plate structure, which is detachably mounted on the lower bowl base 10 and forms a heat-insulating cavity 40 with the lower bowl base 10.

[0032] The lower bowl seat 10 is provided with an annular overlapping platform 11; the energy-concentrating partition 30 is placed on the overlapping platform 11 and separates the upper and lower sides of the heat insulation cavity 40.

[0033] In this invention, an energy-concentrating partition 30 is added to the main heat-insulating cavity 40 formed by the lower bowl base 10 and the upper cover plate 20, dividing the single cavity into two or more independent air chambers. This multi-cavity heat insulation structure effectively increases the number of heat-barrier layers, forming a multi-level heat insulation barrier. Cleaning and maintenance are convenient and efficient, significantly improving the user experience. The detachable design of the upper cover plate 20 and the lower bowl base 10 is key to solving the cleaning problem. When cooking oil or soup drips, simply remove the upper cover plate 20 for cleaning.

[0034] In this embodiment, the energy-concentrating baffle 30 is provided with an arched, protruding, annular mound-like structure 31. The arched, mound-like curved surface simulates the windward slope of a sand dune, forming a concave mirror-like reflection effect, which reflects and focuses the infrared radiation energy scattered in the flame toward the center of the pot bottom.

[0035] In some embodiments, the annular mound structure 31 is provided with multiple mounds of different diameters arranged concentrically. The concentric mounds of different diameters match the temperature gradient distribution at the bottom of the cookware (the center is larger than the edge), reducing heat loss at the edge; the concentric multi-mound structure reproduces the desert ripple landform and establishes a stepped thermal barrier.

[0036] In this embodiment, the outer edge of the energy-concentrating partition 30 is provided with an outwardly extending overlapping edge plate 32, which is placed on the overlapping platform 11 to achieve a quick positioning and installation effect.

[0037] In this embodiment, the overlapping platform 11 is provided with several layers along the vertical direction for arranging multiple energy-concentrating partitions 30 at vertical intervals. Expandable insulation levels: The vertical multi-layer design supports the stacking of 2-4 layers of energy-concentrating partitions 30, achieving a stepped increase in thermal resistance.

[0038] In this embodiment, the outer edge of the lower bowl base 10 is provided with an upwardly extending outer ring wall 12, and a horizontally extending outer edge 13 is provided above the outer ring wall 12; the outer edge of the upper cover plate 20 is provided with an outward flange 21; the outward flange 21 can be fitted onto the outer edge 13. The outward flange 21 and the outer edge 13 form a mechanical interlocking structure.

[0039] Furthermore, the lower bowl base 10 has an upwardly extending inner ring wall 14 on its inner edge; the upper cover plate 20 has an inwardly turned-up edge on its inner edge; the upper cover plate 20 can be placed on top of the lower bowl base 10, and the inwardly turned-up edge can be attached to the outer side of the inner ring wall 14. The inner and outer double ring walls work together to facilitate the quick placement and installation of the upper cover plate 20.

[0040] In this embodiment, the lower bowl base 10 is provided with a number of leg structures 15 on its lower side; the upper cover plate 20 is provided with a number of support ears 50.

[0041] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
