Description

Technical Field

[0001] This utility model relates to the field of stove accessories technology, and in particular to a stove frame with a partitioned oil and water collection 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. Difficult cleaning and maintenance, resulting in a poor user experience: Stove racks are typically made of a single 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.

[0004] 2. 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 the energy-concentrating effect.

[0005] Further improvements are needed. Utility Model Content

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a furnace frame with a partitioned oil and water collection structure.

[0007] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a furnace frame with a partitioned oil and water collection structure, including: a lower bowl seat and an upper cover plate;

[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 upper cover plate has an arc-shaped concave cross section; the upper cover plate has several upward-facing dividing ribs; the dividing ribs span the upper cover plate and divide the upper cover plate into several independent oil collection recesses.

[0010] Optionally, the inner edge of the upper cover plate is provided with an upwardly protruding annular flow-blocking ribs.

[0011] Optionally, the dividing rib has a support groove for fitting the support ear.

[0012] 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.

[0013] Optionally, the inner edge of the lower bowl base is provided with an upwardly extending inner ring wall; the inner edge of the upper cover plate is provided with an inwardly turned edge; the upper cover plate can be placed above the lower bowl base, and the inwardly turned edge can be attached to the outer side of the inner ring wall.

[0014] Optionally, the lower bowl seat is provided with an annular overlapping platform; the overlapping platform is supported by an energy-concentrating partition; the energy-concentrating partition is used to separate the upper and lower sides of the heat insulation cavity.

[0015] Optionally, the energy-concentrating partition is provided with an annular mound-like structure with arched protrusions.

[0016] Optionally, the annular mound structure may have multiple mounds of different diameters arranged at the same center.

[0017] Optionally, the outer edge of the energy-concentrating partition is provided with an outwardly extending overlapping edge plate, which overlaps the overlapping platform.

[0018] Optionally, the overlapping platform is provided with several layers along the vertical direction for arranging multiple energy-concentrating partitions at vertical intervals.

[0019] The beneficial effects of this invention are as follows: The upper cover plate is divided into several independent oil-collecting recessed areas by upward-facing dividing ribs. During cooking, dripping oil and broth are confined to these individual recessed areas, effectively preventing oil from flowing, spreading, and accumulating across the entire stove frame surface. The upper cover plate and lower bowl are detachable. For cleaning, users only need to remove the lightweight upper cover plate, eliminating the need to move the entire heavy stove frame. This greatly reduces the workload. The sealed, insulated cavity structure formed by the upper cover plate and lower bowl is retained, and the internal air layer effectively prevents heat from the flames from being transferred downwards to the stove frame and the area below the cooktop, inheriting the basic energy-saving principle of traditional energy-concentrating stove frames that utilize air insulation.

[0031] Example

[0032] Reference Figures 1 to 3 The present invention proposes a furnace frame with a partitioned oil and water collection structure, comprising: a lower bowl seat 10 and an upper cover plate 20;

[0033] 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.

[0034] The upper cover plate 20 has an arc-shaped concave cross section; the upper cover plate 20 has several upward-facing dividing ribs 21; the dividing ribs 21 span the upper cover plate 20 and divide the upper cover plate 20 into several independent oil collection recesses 22.

[0035] In this invention, the oil and water collection areas are divided into sections. The upward-facing dividing ribs 21 on the surface of the upper cover plate 20 effectively divide the plate into multiple independent oil collection recesses 22. During cooking, dripping oil and soup are confined to these independent recesses, effectively preventing oil from flowing, spreading, and accumulating freely across the entire stove rack surface. The upper cover plate 20 and the lower bowl base 10 are detachable. For cleaning, the user only needs to remove the lightweight upper cover plate 20, eliminating the need to move the entire heavy stove rack. This greatly reduces the operational burden. The sealed, insulated cavity 40 structure formed by the upper cover plate 20 and the lower bowl base 10 is retained, and its internal air layer still effectively prevents heat from the flame from being transferred downwards to the stove rack body and the area below the cooktop, inheriting the basic energy-saving principle of traditional energy-concentrating stove racks that utilize air insulation.

[0036] In this embodiment, the inner edge of the upper cover plate 20 is provided with an upward-protruding annular flow-blocking rib 23. The annular flow-blocking rib 23 on the inner edge forms a barrier, effectively preventing liquids (oil, soup, cleaning water) from flowing down from the inner edge of the stove rack and contaminating the interior of the lower bowl 10, the stove panel, or the burner, and more strictly confining the liquid within the oil collection recess 22 area.

[0037] In this embodiment, the dividing rib 21 has a support groove 24 for mounting the support ear 50. By integrating the support point on the rib, it is avoided to set additional raised support points on the plane of the oil collection depression 22, reducing the dead corners where oil stains accumulate around the support points, and making the surface of the oil collection depression 22 smoother and easier to clean.

[0038] In this embodiment, the lower bowl base 10 has an upwardly extending outer ring wall 12 on its outer edge, and a laterally extending outer edge 13 is provided above the outer ring wall 12; the upper cover plate 20 has an outwardly turned-out edge 25 on its outer edge; the outwardly turned-out edge 25 can be fitted onto the outer edge 13. The structure of the outwardly turned-out edge 25 fitted onto the outer edge 13 provides a stable, firm, and easily aligned detachable connection method, ensuring that the upper cover plate 20 will not accidentally shift or fall off during normal use.

[0039] Furthermore, the lower cup seat 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 cup seat 10, and the inwardly turned-up edge can be attached to the outer side of the inner ring wall 14. This design, with the inwardly turned-up edge attached to the outer side of the inner ring wall 14, provides precise positioning of the inner edge of the upper cover plate 20, ensuring its alignment with the center of the lower cup seat 10. This fitting structure helps to form a good seal on the inner edge, preventing liquid from seeping into the insulation cavity 40 and heat from being lost from the inner edge.

[0040] In this embodiment, the lower bowl base 10 is provided with an annular overlapping platform 11; the overlapping platform 11 is supported by an energy-concentrating partition 30; the energy-concentrating partition 30 is used to separate the upper and lower sides of the heat insulation cavity 40. Adding the energy-concentrating partition 30 to the heat insulation cavity 40 divides it into two (or more) sub-cavities. The multi-layered air cavity can more effectively block heat transfer downwards.

[0041] 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.

[0042] In this embodiment, 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.

[0043] 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.

[0044] 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.

[0045] In this embodiment, a plurality of leg structures 15 are provided on the lower side of the lower bowl base 10.

[0046] 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.
