Description

Technical Field

[0001] This invention relates to the field of gas stove technology, and in particular to a top-intake stove that facilitates cleaning and oil drainage. Background Technology

[0002] A top-intake burner is a type of cooktop burner where the gas distributor and nozzle are located above the cooktop panel. The nozzle's position above the panel ensures high safety; furthermore, the gas distributor and burner cap are typically detachable, allowing for relatively easy cleaning of the cooktop panel. For example, patent number CN212252600U discloses an easy-to-clean top-intake burner.

[0003] This type of top-intake stove typically has a clearance groove in the cooktop panel, with a water tray embedded in the groove. The water tray is bolted to the burner head, and the burner distributor is positioned above the water tray. The burner nozzle and ignition needle extend through the water tray to the burner distributor. However, gaps often exist between the nozzle and ignition needle, or other supporting structures of the burner head, and the clearance holes in the water tray or cooktop panel. Oil and water stains from the cooktop panel surface seep into the cooktop's bottom shell through these gaps, making cleaning difficult and prone to bacterial growth. Therefore, further improvements are sought. Summary of the Invention

[0004] 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 top-intake stove that facilitates cleaning and oil drainage.

[0005] The technical solution adopted by one embodiment of the present invention to solve its technical problem is: a top-intake stove that is easy to clean and drain oil, including a stove bottom shell, a stove panel, a burner base, a top-intake combustion component and an oil collection box; The cooktop panel is installed above the cooktop bottom shell; the cooktop panel has a clearance groove, and the burner base is installed on the cooktop bottom shell, located below the clearance groove; the upper air intake combustion component is placed above the burner base; the burner base has a gas supply channel, and the gas outlet of the gas supply channel extends upward to the upper air intake combustion component. A water tray cover is integrally formed on the top of the burner base; the outer edge of the water tray cover extends and covers the periphery of the clearance groove; a drain outlet is provided below the bottom shell of the stove, and a drain channel is provided on the burner base; the inlet of the drain channel is connected to the upper surface of the burner base, and the outlet is connected to the drain outlet; the oil collection box is placed below the bottom shell of the stove, located below the drain outlet.

[0013] Optionally, the drainage channel and the water pan cover are integrally formed on the burner head base; the burner head base is a casting.

[0014] The beneficial effects of this invention are as follows: By integrally molding the water tray cover into the burner base and extending the outer edge of the water tray cover to cover the perimeter of the cooktop panel clearance groove, an effective shielding and sealing structure is formed. This prevents oil and water stains on the cooktop panel surface from seeping into the cooktop shell through the gaps at the edge of the clearance groove, thus solving the problem of oil leakage. A drainage channel is provided on the burner base. Even if a small amount of liquid splashes onto the area above the burner base during cooking, it can be drained orderly through the drainage channel and collected in the oil collection box, preventing liquid accumulation inside the cooktop and thus preventing bacterial growth and odor. The drainage channel is integrally molded into the burner base, reducing the number of parts and assembly steps, improving production efficiency, and eliminating the potential for connection gaps and leakage in a split drainage structure, ensuring the sealing reliability of the drainage path.

[0022] Example Reference Figures 1 to 4 The present invention proposes a top-intake stove that is easy to clean and drain oil, including a stove bottom shell 10, a stove panel 20, a burner base 30, a top-intake combustion component 40 and an oil collection box 50. The cooktop panel 20 covers the top of the cooktop bottom shell 10; the cooktop panel 20 has a relief groove 21, and the burner base 30 is installed on the cooktop bottom shell 10, located below the relief groove 21; the upper air intake combustion component 40 is placed above the burner base 30; the burner base 30 has a gas supply channel 31, and the gas outlet seat 32 of the gas supply channel 31 extends upward to the upper air intake combustion component 40; A water tray cover 33 is integrally formed on the top of the burner base 30; the outer edge of the water tray cover 33 extends and covers the periphery of the relief groove 21; a drain outlet 11 is provided below the bottom shell 10 of the stove, and a drain channel 34 is provided on the burner base 30; the inlet of the drain channel 34 is connected to the upper surface of the burner base 30, and the outlet is connected to the drain outlet 11; the oil collection box 50 is placed below the bottom shell 10 of the stove, located below the drain outlet 11.

[0023] The beneficial effects of this invention are as follows: By integrally molding the water tray cover 33 onto the burner base 30 and extending the outer edge of the water tray cover 33 to cover the periphery of the clearance groove 21 on the cooktop panel 20, an effective shielding and sealing structure is formed, preventing oil and water stains on the surface of the cooktop panel 20 from seeping into the cooktop bottom shell 10 through the gaps at the edge of the clearance groove 21, thus solving the problem of oil leakage. A drainage channel 34 is provided on the burner base 30. Even if a small amount of liquid splashes onto the area above the burner base 30 during cooking, it can be orderly discharged through the drainage channel 34 and collected in the oil collection box 50, preventing liquid accumulation inside the cooktop and preventing bacterial growth and odor generation. The drainage channel 34 is integrally molded into the burner base 30, reducing the number of parts and assembly steps, improving production efficiency, and eliminating the potential for connection gaps and leakage in a split drainage structure, ensuring the sealing reliability of the drainage path.

[0024] In this embodiment, the drainage channel 34 is integrally formed into the burner base 30. Integrating the drainage channel 34 into the burner base 30 avoids the need for additional drainage pipe fittings on the burner base 30, reducing assembly steps and the number of parts, and improving production efficiency and structural reliability. Simultaneously, the integral structure eliminates the connection gaps that might exist in a split drainage channel 34, preventing oil and wastewater stains from leaking from the connection points into other parts of the cooktop bottom shell 10, further ensuring the sealing and reliability of the drainage path.

[0025] In this embodiment, the drainage channel 34 is located in the middle of the furnace head base 30 and has a vertically continuous channel structure. By placing the drainage channel 34 in the middle of the furnace head base 30 and having a vertically continuous structure, oil and wastewater flowing into the upper surface of the furnace head base 30 from all directions can collect in the middle and be discharged downwards through the drainage channel 34. The drainage path is simple and efficient, with no dead corners or residue. The vertically continuous structure also facilitates casting demolding and reduces processing difficulty.

[0026] In some embodiments, the water pan cover 33 has an inverted conical structure, and the upper surface of the burner base 30 is located below the cooktop panel 20. The inverted conical structure of the water pan cover 33, where its surface gradually decreases from the center to the outer edge, guides oily and dirty water stains that have seeped into the water pan cover 33 to naturally converge and flow towards the center of the water pan cover 33 or the inlet of the drainage channel 34 under the action of gravity, accelerating the discharge of liquid, preventing liquid from accumulating on the water pan cover 33, and improving drainage efficiency. In addition, this structure also reduces the overall height of the burner and the overall height space of the cooktop.

[0027] In this embodiment, a sealing structure is provided between the lower outer edge of the water pan cover 33 and the cooktop panel 20. A sealant or gasket is provided between the lower outer edge of the water pan cover 33 and the cooktop panel 20 to further seal the tiny gaps between them, achieving a sealed protection.

[0028] Preferably, the sealing structure is a sealant or a gasket. After curing, the sealant bonds tightly to both, providing a more durable seal, and is less prone to aging and detachment, making it suitable for long-term use. The gasket features a removable design; if it ages, breaks, or becomes contaminated with oil, the user can directly remove and replace it or clean it. The sealant can be selected from silicone sealant, high-temperature nitrile sealant, or polysulfide sealant, while the gasket can be selected from high-temperature silicone gaskets, fluororubber gaskets, nitrile rubber gaskets, or graphite gaskets.

[0029] In this embodiment, the water tray cover 33 is disc-shaped; the outer diameter of the water tray cover 33 is larger than the diameter of the clearance groove 21 on the cooktop panel 20. The disc-shaped water tray cover 33 matches the common circular shape of the clearance groove 21 on the cooktop panel 20, resulting in a simple and beautiful appearance that is easy to process and shape. At the same time, the disc-shaped structure has no sharp edges, making it less likely to create hard-to-clean corners during cleaning, further improving the cooktop's easy-to-clean performance.

[0030] In this embodiment, a plurality of fixing grooves 35 for fixing the stove ears 60 are provided at intervals on the upper outer edge of the water pan cover 33. The fixing grooves 35 on the upper outer edge of the water pan cover 33 are used to fix the stove ears 60 (pot rack), ensuring that the stove ears 60 are stably installed on the water pan cover 33, preventing displacement or shaking during use, and improving the safety and stability of cooking operations. The fixing grooves 35 are integrally formed with the water pan cover 33, resulting in a simple structure and eliminating the need for additional support brackets.

[0031] In this embodiment, the drainage channel 34 and the water pan cover 33 are integrally formed on the burner base 30; the burner base 30 is a casting. Integrating the drainage channel 34 and the water pan cover 33 into the burner base 30, and manufacturing the burner base 30 using a casting process, allows the water pan cover 33, drainage channel 34, and burner base 30 to form an integral structure, significantly reducing the number of parts and assembly steps, and lowering manufacturing costs. Castings possess excellent structural strength and sealing properties, effectively preventing loosening and leakage problems caused by a split structure, thus improving the overall reliability and service life of the stove.

[0032] This invention relates to a top-intake stove that facilitates cleaning and oil drainage. Its working principle is as follows: When the stove is in normal use, the stove panel 20 covers the top of the stove base shell 10, and the burner base 30 is installed inside the stove base shell 10 and located below the clearance groove 21 of the stove panel 20. The upper air intake combustion component 40 is placed above the burner base 30 and receives gas supply through the gas supply channel 31 inside the burner base 30. The gas outlet 32 ​​of the gas supply channel 31 extends upward to the upper air intake combustion component 40 to provide gas for combustion. Because this stove adopts an upper air intake structure, primary air enters the combustion component from above the stove panel 20, resulting in complete combustion and high safety.

[0033] When oil, soup, or water stains are produced during cooking or during cleaning and flow onto the surface of the cooktop panel 20, these liquids can easily flow into the relief groove 21 of the cooktop panel 20. Since a water pan cover 33 is integrally formed on the top of the burner base 30, and the outer edge of the water pan cover 33 extends and covers the periphery of the relief groove 21, forming a barrier and seal, liquid cannot seep into the interior of the cooktop bottom shell 10 from the gaps at the edge of the relief groove 21.

[0034] If a small amount of liquid splashes onto the area above the water pan cover 33 during cooking, the liquid will naturally collect and flow towards the center along the inclined surface of the water pan cover 33 due to its inverted conical structure, where the surface gradually slopes downwards from the outer edge. A drain channel 34 is provided in the middle of the burner base 30, with its inlet connected to the upper surface of the burner base 30, located in the center or lower part of the water pan cover 33. The collected liquid enters the drain channel 34 through its inlet, flows downwards through the drain channel 34, and is discharged from the outlet to the drain outlet 11 below the cooktop base 10.

[0035] The drain channel 34 is integrally formed into the burner base 30, forming a vertically continuous channel structure. Liquid can smoothly drain from top to bottom under gravity without the need for an additional power device. An oil collection box 50 is placed below the cooktop base 10, located below the drain outlet 11. Liquid flowing from the drain outlet 11 falls into the oil collection box 50 and is collected. Users can periodically remove the oil collection box 50 for cleaning, making the process convenient and quick. Several fixing grooves 35 are also provided on the upper outer edge of the water tray cover 33 for fixing the burner ears 60 (pot supports). After the burner ears 60 are inserted into the fixing grooves 35, they can stably support the pots and prevent displacement or shaking during use, ensuring the safety and stability of cooking operations.

[0036] Of course, the present invention 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 the present invention. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
