Description

Technical Field

[0001] This invention relates to the field of gas stove technology, and more specifically, to improvements in combustion stoves. Background Technology

[0002] Currently, most conventional built-in gas cooktops on the market have a complete bottom shell, with the gas valve assembly and control system all enclosed within a sealed cavity formed by the cooktop panel and the bottom shell. When the cooktop valve body, control circuit, or digital display components malfunction and require repair or maintenance, repair personnel must lift the entire cooktop out of the cabinet and completely disassemble the cooktop panel before they can access the internal gas valve assembly. Lifting the entire cooktop is cumbersome and labor-intensive, and the disassembly and assembly process is extremely prone to scratching the tempered glass panel and damaging the burner. Furthermore, lifting the cooktop in the confined space of the cabinet poses safety hazards such as gas hose leakage and damage to the cabinet. After-sales repair and routine maintenance are also extremely inefficient. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a bottomless combustion stove, which offers advantages such as convenient maintenance, elimination of bottom material and processing steps, and effective cost savings. It also solves the problem that traditional stoves require disassembly of the entire unit for gas intake pipe maintenance, resulting in poor convenience for intake assembly and pipe maintenance.

[0007] Furthermore, the air supply valve body assembly includes a flow valve, an air inlet pipe, an air connector, and a controller; the flow valve is fixed to the lower surface of the maintenance cover plate, the controller is connected to the flow valve, the air inlet end of the flow valve is connected to the air inlet pipe, the air connector is installed at the end of the air inlet pipe, and the air connector is exposed through the air inlet pipe perforation.

[0008] Furthermore, the burner assembly includes a left burner and a right burner. Each burner assembly includes a central burner cap, an outer ring burner cap, and a furnace frame. The central burner cap is located at the center of the outer ring burner cap, and the central burner cap and the outer ring burner cap are assembled inside the furnace frame.

[0009] Furthermore, the stove panel is any one of tempered glass integrated panel, ceramic integrated panel, or metal integrated panel.

[0010] Furthermore, the maintenance cover is an integrally stamped thin plate, and the maintenance cover is detachably connected to the front step of the stove panel.

[0011] Furthermore, the sealing gasket is sandwiched between the knob and the maintenance cover to form a waterproof sealing structure.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the present invention provides a bottomless combustion stove, which has the following beneficial effects:

[0014] It eliminates the closed bottom shell structure, allowing it to be placed directly on a flat countertop for use. The countertop design is simple, lightweight, and easy to move and clean. The gas supply valve assembly is covered by a removable maintenance cover, eliminating the need to lift or disassemble the entire stove panel during maintenance. Only the maintenance cover needs to be removed to inspect the valve body and control components. The gas inlet connector is directly exposed through a hole in the stove panel, making the assembly and maintenance of the gas inlet pipe convenient. This significantly reduces the difficulty of stove maintenance and saves on bottom shell materials and processing steps, effectively saving production costs. Attached Figure Description
