Description

Technical Field

[0001] This utility model relates to the field of kitchen stove technology, and in particular to an energy-saving gas-fired large pot stove. Background Technology

[0002] Large-scale cooking stoves are core cooking equipment in collective dining units such as government canteens, schools, and catering companies. Their thermal efficiency and energy-saving performance directly affect operating costs and energy consumption. Currently, commercial gas-fired large-scale cooking stoves typically consist of a furnace body, burner, and burner chamber. Among these, the burner chamber, as a key component that guides the flame and gathers heat energy, has a crucial impact on thermal efficiency due to its structural design. Traditional burner chambers use a one-piece molded fixed structure, with the radius of curvature and depth of its inner cavity contour being fixed and non-adjustable. However, different manufacturers use different cookware standards, resulting in a specific burner chamber only achieving a relatively optimized match with a pot bottom of a specific curvature. When changing to different sizes of cookware, the gap between the upper edge of the burner chamber and the outer edge of the pot bottom becomes too large. This excessive gap becomes a preferential leakage channel for high-temperature flue gas, causing a large amount of heat to escape directly into the environment without effective heat exchange with the pot bottom, resulting in significant heat waste. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses an energy-saving gas-fired large pot stove. It adopts a height-adjustable stove chamber structure, which allows the gap between the stove chamber and the bottom of the pot to be adjustable. This enables the upper edge of the stove chamber to adaptively match the bottom contour of pots with different curvatures and deformations, thus solving the problems of poor compatibility and easy leakage of high-temperature flue gas in existing fixed stove chambers.

[0004] The specific technical solution is as follows:

[0005] An energy-saving gas-fired wok stove includes a stove frame, a stove chamber, and a lifting mechanism. The stove frame has a stove opening on its surface, with the inner wall of the opening running longitudinally. The stove chamber is movably mounted inside the stove opening, with its upper side wall running longitudinally and fitting against the inner wall of the stove opening. A support base is connected to the bottom of the stove chamber by longitudinally arranged support rods. The support base is lifted and lowered by the lifting mechanism, which includes a screw jack and telescopic sleeves. The telescopic sleeves are distributed around the bottom of the support base, with their bottoms fixed to the inner wall of the stove frame. The top of the telescopic rod inside the telescopic sleeve is fixed to the bottom of the support base. The top of the screw of the screw jack is fixedly connected to the bottom of the support base via a flange. A servo motor is fixed to one side of the screw jack, and the output shaft of the servo motor is connected to the worm gear of the screw jack, allowing the servo motor to drive the screw jack and raise and lower the screw, thereby adjusting the height of the stove chamber.

[0006] Furthermore, a flue gas passage is provided on the inner wall of the stove opening, and one end of the flue gas passage is connected to an external exhaust pipe.

[0007] Furthermore, the bottom of the stove body is flat, and the lower side wall of the stove body is curved.

[0008] Furthermore, a burner head is provided on the bottom plane of the stove body, and a gas pipe extending to the outside of the stove frame is connected to the bottom of the burner head.

[0009] Furthermore, the furnace body includes a metal outer shell and an inner lining made of refractory material disposed inside the outer shell.

[0010] Furthermore, the outer wall of the outer shell at the upper end of the stove body is provided with several longitudinally arranged annular protrusions, and the outer walls of the annular protrusions are all fitted to the inner wall of the stove opening.

[0011] Furthermore, the top edge of the stove opening is provided with a pot ring for placing cookware.

[0012] Furthermore, the bottom of the screw jack extends downward through the bottom of the stove frame, and the bottom of the stove frame is provided with support legs around its perimeter.

[0013] Furthermore, a fan hood is installed at the bottom of the stove body, and a connector pipe is bent at the bottom of the fan hood. The connector pipe is connected to the air outlet of the fan through a telescopic flexible hose.

[0014] The beneficial effects of this utility model are reflected in:

[0015] This utility model adopts a height-adjustable stove structure, which realizes the adjustable gap between the stove and the bottom of the pot. This allows the upper edge of the stove to adapt to and match the contour of the pot bottom with different curvatures. It solves the problems of poor compatibility and serious leakage of high-temperature flue gas caused by differences in pot specifications and deformation in traditional fixed stoves, effectively improving thermal efficiency and reducing energy consumption.
