Description

Technical Field

[0001] The invention relates to the technical field related to carbon furnaces, and in particular to a carbon ignition furnace. Background Art

[0002] In the existing carbon furnace used for electric heating ignition, the charcoal placed in the combustion cavity of the carbon furnace is generally heated and ignited by a heating tube. Since the combustion cavity of the carbon furnace has a small space, it is difficult to quickly replenish air during the ignition and burning of the charcoal to make the charcoal burn quickly and stably. There are disadvantages such as slow charcoal ignition speed and unstable combustion heat. At the same time, the existing carbon furnace does not have an ash receiving component. The ashes after the charcoal is burned fall directly into the combustion cavity of the carbon furnace, which is difficult to clean. In addition, there is no heat insulation component. During use, the outer wall temperature of the carbon furnace is high, which is easy to burn and has low safety. In addition, there is no timing function, and long-term burning is easy to cause safety hazards such as electrical fires. Most of the heating tubes in the prior art use stainless steel heating tubes for heating. This type of stainless steel heating tube is heated by a stainless steel tube, and the contact metal heat conduction is inefficient. Summary of the invention

[0034] The technical solutions of the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] See also Figures 1 to 4A carbon-lighting furnace comprises: a furnace body 1, a combustion cavity 2 with an opening upwardly arranged on the furnace body 1, a heating tube 3 arranged in the combustion cavity 2, a detachable carbon box 4 arranged on the upper side of the heating tube 3 in the combustion cavity 2, and a detachable ash tray 5 arranged on the lower side of the heating tube 3 in the combustion cavity 2. A heat insulation layer 6 is arranged on the outer side of the combustion cavity 2 in the furnace body 1, and a blast device 7 is connected to the lower side of the heat insulation layer 6. A circuit board is arranged on the blast device 7, and the circuit board is connected to a fan 73, and the fan 73 is arranged at the bottom of the combustion cavity 2. This carbon-lighting furnace has an integrated structure and is designed with an air insulation layer 6. In actual application, the outer shell temperature does not exceed 60°C, which is safer and can be touched directly. In addition, a blast device 7 is designed at the bottom, and an air duct is designed to supply oxygen to the charcoal for combustion. At the same time, after the heating stops, ventilation and cooling are carried out to quickly reduce the temperature of the furnace body 1. The charcoal ignition furnace is provided with a heat insulation layer 6 and a blast device 7 to insulate the furnace body 1 and to supply air for heat dissipation, so that the temperature of the outer wall of the charcoal ignition furnace is not high, and it is not easy to be burned during use. The blast device 7 is provided to replenish air in time, so that the charcoal can be burned quickly, stably and fully with high efficiency. The heating tube is a quartz heating tube, which is heated by a quartz heating tube 3 and is heated by infrared radiation. The heating efficiency is high, and the charcoal is quickly ignited by the photothermal effect of the quartz heating tube 3. Different from the traditional stainless steel heating tube, the temperature rises quickly and can reach the set power temperature in 10 seconds, and the ignition efficiency is increased by at least one time.

[0036] Specifically, see Figures 1 to 4 The charcoal box 4 is fixedly connected to the heat insulation layer 6 through a connecting piece. The ash tray 5 is connected to the bottom of the heat insulation layer 6 through screws. Ashes generated during the burning of charcoal fall into the ash tray 5 on the lower side of the heating tube 3. When cleaning, the ash tray 5 only needs to be removed from the combustion cavity 2 and cleaned, which is convenient for quick cleaning.

[0037] Further, see Figures 1 to 4, the heating tube 3 is a quartz heating tube 3, and both ends of the quartz heating tube 3 are fixed on the insulation layer 6. The charcoal is quickly ignited by the photothermal effect of the quartz heating tube 3, and the temperature rises quickly. In practical applications, it can rise to the set power temperature in 10 seconds, and the ignition efficiency is increased by at least one time. The quartz heating tube 3 is heated by far-infrared radiation and has high efficiency. The quartz heating tube 3 is a special industrial technology glass made of silicon dioxide as the shell, and adopts a milky quartz glass tube processed by a special process and a resistance synthetic material as a heating element. The tubular heater using the infrared principle has a very small thermal expansion coefficient and can withstand drastic temperature changes. The quartz glass is heated to about 1100°C and will not burst when placed in normal temperature water. At the same time, quartz glass has good insulation properties at high temperatures to avoid risks such as electric shock. In addition, the softening point temperature of quartz glass is about 1730°C, and it can be used for a long time at 1100°C. The maximum use temperature for a short time can reach 1450°C, and the high temperature resistance is very good. At the same time, the corrosion resistance is also very good. Except for hydrofluoric acid, quartz glass hardly reacts chemically with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially its chemical stability at high temperatures is unmatched by any other engineering material.

[0038] Preferably, see Figures 1 to 4 The heating tube 3 is connected to the circuit board, and a temperature sensor is provided in the combustion cavity 2, and the temperature sensor is connected to the circuit board. The temperature sensor collects the temperature of the heating tube 3 and the combustion cavity 2 and transmits it to the controller of the circuit board. The controller collects the temperature information, processes the information, and then issues an instruction to adjust the temperature of the heating tube 3.

[0039] Alternatively, see Figures 1 to 4 The circuit board is connected with a timing device, and the timing device is connected with a potential switch knob 8, and the potential switch knob 8 is located outside the blast device 7. The design of the timing device is more worry-free, and the timing is automatically turned off to avoid safety hazards after people leave. The timing device is connected to the controller on the circuit board, and the controller collects the set time and performs timing calculation. The potential switch knob 8 is used to set the timing time of the timing device.

[0040] Specifically, see Figures 1 to 4 The blower 7 is provided with a cavity 71, the fan 73 is provided in the cavity 71, a shell 72 is provided outside the cavity 71, and a plurality of vents 74 are provided on the shell 72, so that the cavity 71 is connected with the outside to circulate air, achieve a good heat dissipation effect and quickly replenish air, so that the charcoal in the combustion cavity 2 can be quickly ignited and stably burned. The cavity 71 is provided to protect the circuit board and the fan 73 and reduce the entry of dust.

[0041] Further, see Figures 1 to 4 The cavity 71 is provided with a plurality of support columns 75, one end of which is connected to the top of the cavity 71, and the other end is connected to the bottom of the cavity 71. The support columns 75 are used to support the furnace body 1 above, so that the structure of the blast device 7 is stable. Specifically, the bottom of the shell 72 is also connected to a plurality of support legs 76 for placing the carbon ignition furnace. Preferably, there are four support legs 76, which can also be connected to the bottom of the shell 72 in a detachable manner for easy storage.

[0042] In some preferred embodiments, see Figures 1 to 4 The ash receiving tray 5 is provided with a groove 51 corresponding to the heating tube 3, and the heating tube 3 is located above the groove 51. A connecting portion 52 is provided between the grooves 51, and a plurality of ventilation holes 53 are provided on the connecting portion 52. The ventilation holes 53 are connected to the fan 73, so that the wind of the fan 73 blows onto the carbon loading box 4, providing oxygen for the charcoal to be burned, so that it can burn stably. The bottom of the carbon loading tray is provided with a plurality of ventilation grooves 41, and the ventilation grooves 41 are located above the heating tube 3, so that the charcoal ash in the carbon loading box 4 just falls into the groove 51 and catches the charcoal ash.

[0043] See also Figures 1 to 4 The shell 72 is connected to a handle 9 outside, and the handle 9 is fixedly connected to the shell 72 to facilitate taking the carbon ignition furnace.

[0044] Further, see Figures 1 to 4 The housing 72 is also provided with a power switch 77 and a power line interface 78 to provide power to the heating tube 3, the circuit board, the fan 73, etc. In addition, a battery box for placing dry batteries is also provided in the housing 72, and a detachable battery box cover is provided on the battery box, which is electrically connected to the fan 73, the heating tube 3, the circuit board, etc.

[0045] In some optional embodiments, see Figures 1 to 4 The fan 73 is connected to a speed controller, which controls the speed of the fan 73 and thus controls the air intake in the combustion cavity 2, controls the combustion speed of the charcoal in the carbon box 4 and the heat dissipation temperature of the heat insulation layer 6. The speed controller controls the firepower of the charcoal ignition furnace, so that the charcoal ignition furnace not only meets the needs of conventional barbecue, but also has the functions of roasting, stewing, boiling, frying, steaming, stewing, hot pot, heating, etc. It can be used outdoors and indoors, and can use charcoal, industrial wax, or industrial alcohol and other fuels to improve its applicable occasions. The battery box is also connected to a power port, which is electrically connected to an external power supply, and the external power supply can be a power bank, a charger, a transformer power supply, etc.
