Technical Field

[0001] The present invention relates to a kitchen stove with a stove plate burning device in the field of IPC classification numbers F23D and F24C, in particular to a hidden suspended burner assembly of the stove. Background Art

[0002] With the increasing awareness of safety, energy conservation, and environmental protection, as well as changes in fuel types, structural innovations in kitchen stoves are constantly emerging. For example, Chinese patent document CN209991453U announces an improved clean-type double-inner-flame household gas burner, wherein the burner head includes an upper ejection cover and a lower ejection cover, each of the upper ejection cover and the lower ejection cover is provided with an outer ring ejection groove and an inner ring ejection groove, the two outer ring ejection grooves and the two inner ring ejection grooves are correspondingly combined up and down to form an outer ring ejection tube and an inner ring ejection tube, the upper ejection cover is connected to a plurality of connecting legs, the upper ejection cover is mounted on the bottom shell of the stove through the connecting legs, the upper ejection cover extends upward with a plurality of connecting bosses with a center hole, the corresponding liquid collecting pan is provided with a liquid collecting pan connecting hole which is mounted in conjunction with the center hole, and the burner head is installed and fixed and the liquid collecting pan is pressed against the stove panel by fasteners passing through the liquid collecting pan connecting hole. This mounting structure concentrates the force point on the upper ejection cover, thereby avoiding the occurrence of a gap between the upper ejection cover and the lower ejection cover due to different force directions, thereby affecting the sealing performance of the burner head.

[0003] For another example, Chinese patent document CN112303676A discloses a plate-type stove with a burner, comprising a stove panel, a first support seat being provided on the lower left side of the stove panel, a second support seat being provided on the lower right side of the stove panel, a stove assembly being provided on the upper right side of the base surface of the stove panel, the stove assembly comprising a liquid collecting pan, a cleaning pan, an outer ring fire cover, an inner ring fire cover, a stove support and an ignition burner, an air intake branch pipe being connected to the left side of the ignition burner, an air intake main pipe being horizontally installed on the right side of the fixed seat, the air intake branch pipe being connected to the air intake main pipe through an ignition valve, and being located inside the ignition burner through the inner ring fire cover and the outer ring fire cover, which can concentrate flame and heat and improve the utilization rate of the heat of gas combustion, and the lower side of the stove support is provided with a rectangular chamfered structure, which can be installed and connected correspondingly to the cleaning pan, and the cleaning pan can position the stove support, so that the stability of the stove support is higher.

[0004] For another example, Chinese patent document CN208871618U discloses a stove burner, which includes a burner head, an outer ring honeycomb fire cover and an inner ring fire cover, wherein the burner head is provided with an outer ring ejector tube and an inner ring ejector tube, and further includes a combustion seat, which is detachably arranged on the burner head, and the combustion seat includes an outer ring combustion chamber and an inner ring combustion chamber, wherein the outer ring combustion chamber is connected to the outer ring ejector tube, and the inner ring combustion chamber is connected to the inner ring ejector tube, and a swirl plate is provided on the outer ring combustion chamber, wherein the swirl plate is provided with a guide hole, and the swirl plate divides the outer ring combustion chamber into a gas premixing chamber and a gas combustion chamber. Since the gas and air are fully mixed in the gas premixing chamber, the gas entering the gas combustion chamber is fully burned, thereby improving the combustion efficiency, and the swirl plate blocks the high-temperature gas in the gas combustion chamber from entering the gas premixing chamber, thereby avoiding the backfire phenomenon, preventing the high-temperature gas from being dissipated into the burner head to cause heat loss, and preventing the burner head temperature from rising.

[0005] For example, Chinese patent document CN104913345A discloses a gas stove and an integrated stove having the same. The gas stove includes a main table, a burner, and a burner head. The upper surface of the main table is provided with a movably connected burner head cover. The burner head cover and the main table are enclosed to form a cavity. The burner head is disposed within the cavity. The burner is connected to the burner head, and the burner is provided with a combustion hole, which is disposed above the burner head cover. The burner and burner head are both disposed above the main table. By removing the burner head cover, the burner head can be easily repaired and maintained. The integrated stove having the gas stove is also easier to maintain.

[0006] As for the various technical solutions corresponding to the above IPC classifications, gas stove designers have their own opinions. They all demonstrate their talents to further enhance the convenience of stove use and fully improve the thermal efficiency of gas, driven by the needs of safety, energy conservation, and environmental protection. However, there is no end in sight, and continuous efforts are still needed to improve the thermal efficiency of gas and further improve the safety and environmental protection standards of household stoves. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a hidden suspended burner assembly for a stove, which can create a situation of large, medium and small fire gas supply during the dynamic process of the stove, so that the gas entering the burner can be fully burned and the energy saving and environmental protection efficiency can be improved.
