Description

Technical Field

[0001] The present invention relates to the field of burners, and particularly to a combustion device, a heating furnace and a cooking stove. Background Art

[0002] Currently, most liquid fuel (such as alcohol, gasoline, etc.) burners applied to heating furnaces, cooking stoves, etc. adopt a porous fire pan. The fire pan is generally made of metal materials, and the fire holes are opened during the forming process or subsequent machining processes. However, due to the limitations of the casting process or machining process, generally the diameters of such fire holes are relatively large, which is not conducive to the full combustion of the fuel and the uniformity of the flame, so the thermal efficiency is not high. Summary of the Invention

[0003] An object of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide a combustion device, a heating furnace and a cooking stove, which can improve the uniformity of the flame and the thermal efficiency.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] A combustion device, comprising a combustion pan main body and a fuel supply assembly. The combustion pan main body includes at least one group of ceramic pans. The ceramic pan has a combustion surface capable of volatilizing or overflowing liquid fuel. The fuel supply assembly can supply liquid fuel (such as alcohol, gasoline, etc.) into the ceramic pan, and the liquid fuel can penetrate or be transported to the combustion surface in the ceramic pan.

[0006] At least one of the above technical solutions has at least the following advantages or beneficial effects: By utilizing the microporous structure inside and on the surface of the ceramic, the liquid fuel can be evenly distributed on the combustion surface, making the flame distribution more uniform and improving the thermal efficiency.

[0007] In some specific embodiments thereof, the combustion disk body includes a first ceramic disk and a second ceramic disk. Both the first ceramic disk and the second ceramic disk have a smooth surface and a water absorption surface. The first ceramic disk and the second ceramic disk are stacked and placed, and their smooth surfaces are in contact with each other. A conduction member capable of communicating their interiors is provided between the first ceramic disk and the second ceramic disk. The water absorption surface of the first ceramic disk or the second ceramic disk can form the combustion surface. During use, the liquid fuel is transported to the water absorption surface of the first ceramic disk or the second ceramic disk and adsorbed into the interior of the ceramic, and then transported to the water absorption surface of the second ceramic disk or the first ceramic disk through the interior of the ceramic and the conduction member, so that the liquid fuel can be evenly transported or penetrated to the combustion surface, improving the uniformity of the flame. And when the ceramic disk is produced, due to the limitation of the mold, at least one surface of the ceramic disk is a smooth surface, which is not conducive to the absorption of liquid. The specific embodiments of the present invention configure two groups of ceramic disks, make their smooth surfaces correspond to each other and conduct through the conduction member, so that the liquid fuel can be directly transmitted from the lower part to the upper part, forming a ceramic disk combination that can transport liquid fuel and can be used for combustion, overcoming the problem that traditional ceramic disks are difficult to be used as combustion disks, and facilitating the overall structure layout of the heating furnace.

[0008] In some specific embodiments thereof, the conduction member is a plurality of conduction tubes horizontally arranged between the first ceramic disk and the second ceramic disk. A plurality of through holes communicating with the interior of the first ceramic disk or the second ceramic disk are provided on the conduction tubes. The interiors of the first ceramic disk and the second ceramic disk are conducted by the conduction tubes, overcoming the problem that the smooth surface affects liquid absorption and ensuring the normal transportation of the liquid fuel.

[0009] In some specific embodiments thereof, the conduction tubes are arranged in a spiral shape, a petal shape or a radial shape, so that the conduction tubes are more evenly distributed, improving the uniformity of the distribution of the liquid fuel in the ceramic disk.

[0010] In some specific embodiments thereof, a furnace body shell is further included. An opening is provided in the upper part of the furnace body shell. The combustion disk body is arranged on the lower side of the opening, and the combustion surface faces upward and corresponds to the opening, forming a heat output port, which is convenient for heat output.

[0011] In some specific embodiments thereof, the fuel supply assembly includes a container and a pump arranged in the furnace body shell. The water absorption surface of the first ceramic disk forms the combustion surface. The inlet end of the pump is connected to the interior of the container through a suction pipe, and the outlet end of the pump is connected to the water absorption surface of the second ceramic disk through a discharge pipe, forming fuel supply.

[0012] In some specific embodiments thereof, a filter is configured at the suction pipe to reduce the entry of solid particles and the like into the pump and the combustion disk body, reduce the blockage of the combustion disk body, and extend its service life.

[0013] In some specific embodiments, the pump is an electromagnetic pump, and the electromagnetic pump is configured with a thyristor controller capable of adjusting its flow rate to control the delivery flow rate of the liquid fuel and achieve the function of controlling the flame.

[0014] In some specific embodiments, it further includes an igniter, and the igniter is arranged corresponding to the water absorption surface of the first ceramic disc to achieve the function of electronic ignition.

[0015] In some specific embodiments, a liquid receiving tray corresponding to the water absorption surface of the second ceramic disc is arranged below the water absorption surface of the second ceramic disc to prevent the liquid from dripping from the water absorption surface of the second ceramic disc onto other components.

[0016] In some specific embodiments, there is a gap between the main body of the combustion disc and the upper inner wall of the furnace body shell, and air inlets are arranged on the side and / or bottom of the furnace body shell. External air can enter the furnace body shell through the air inlets and enter above the water absorption surface of the first ceramic disc through the gap, forming a secondary air supply to improve the low power of combustion.

By utilizing the microporous structure inside and on the surface of the ceramic, the liquid fuel can be evenly distributed on the combustion surface, making the flame distribution more uniform and improving the thermal efficiency.

[0026] In some specific embodiments thereof, as Figure 1 shown, the combustion tray main body includes: a first ceramic tray 100 and a second ceramic tray 120. Both the first ceramic tray 100 and the second ceramic tray 120 have a smooth surface 101 and a water absorption surface 102.

A conduction member capable of communicating their interiors is provided between the first ceramic tray 100 and the second ceramic tray 120. The water absorption surface 102 of the first ceramic tray 100 or the second ceramic tray 120 can form a combustion surface. During use, the liquid fuel is transported to the water absorption surface 102 of the first ceramic tray 100 or the second ceramic tray 120 and adsorbed into the ceramic interior, and is transported to the water absorption surface 102 of the second ceramic tray 120 or the first ceramic tray 100 through the ceramic interior and the conduction member, so that the liquid fuel can be evenly transported or penetrated to the combustion surface, improving the uniformity of the flame. And when the ceramic tray is produced, due to the limitation of the mold, at least one surface of the ceramic tray is a smooth surface, which is not conducive to liquid absorption. The specific embodiment of the present invention configures two groups of ceramic trays, makes their smooth surfaces correspond to each other and is conducted through the conduction member, so that the liquid fuel can be directly transmitted from below to above, forming a ceramic tray combination that can transport liquid fuel and can be used for combustion, overcoming the problem that traditional ceramic trays are difficult to be used as combustion trays and facilitating the overall structure layout of the heating furnace.
