Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating equipment, in particular to an electric heating tube coil assembly. Background Art
[0002] The patent with publication number CN207341646U discloses a heating pot body for household appliances, including a pot body side wall and a heating plate. The pot body side wall is a barrel body with upper and lower openings. The heating plate includes a bottom plate, and the bottom end surface of the bottom plate is printed with a heating wire and a conductive contact. The side of the bottom plate is provided with a step. The bottom of the pot body side wall is an inwardly curved fillet. The height of the step is equal to the height of the fillet side. The fillet side of the pot body side wall is welded to the step by a laser welding process, so that the welding gap is extremely small.
[0003] The heating plate of the above technology is directly installed at the bottom of the pot body. When the bottom is burnt, the local temperature on the heating plate rises quickly, making it difficult to take away the local heat of the heating plate, and the resistance wire in the heating plate is prone to fuse.
[0004] Therefore, there is an urgent need for an electric heating tube coil assembly that can reduce the risk of resistance wire fusing. Utility Model Content
[0005] In order to solve the above technical problems, the purpose of the utility model is to provide an electric heating tube coil assembly that can reduce the risk of resistance wire fusing.
[0006] The technical solution adopted by the utility model to solve the problem is:
[0007] An electric heating tube coil assembly comprises a bottom plate and an electric heating tube, wherein the electric heating tube is installed at the bottom of the bottom plate, and an aluminum layer is arranged between the bottom plate and the electric heating tube.
[0008] As a further improvement of the above technical solution, the aluminum layer includes an aluminum plate, the aluminum plate is fixedly installed on the bottom of the chassis, and the electric heating tube is installed on the bottom of the aluminum plate.
[0009] As a further improvement of the above technical solution, the aluminum layer includes an aluminum shell, and the aluminum shell is arranged on the outer surface of the electric heating tube.
[0010] As a further improvement of the above technical solution, the aluminum plate is welded to the bottom of the chassis, and the chassis is made of stainless steel.
[0011] As a further improvement of the above technical solution, the electric heating pipe includes a pipe and a resistance wire installed in the pipe, and the material of the pipe is iron. The electric heating pipe is made of iron pipe material, which has greater heat resistance than aluminum material and can improve its service life. At the same time, the iron pipe is wrapped with aluminum pipe, and the inner wall of the aluminum pipe and the outer wall of the iron pipe are made of gapless process technology, which has good heat transfer. After the iron pipe is wrapped with aluminum pipe, it is very convenient to braze with aluminum plate and stainless steel plate as one, and the thermal conductivity is good.
[0012] As a further improvement of the above technical solution, it also includes a thermostat, which is fixedly mounted on the electric heating tube and electrically connected to the electric heating tube. After the food is burnt to the bottom, without the intervention of the thermostat, the temperature on the aluminum shell is likely to exceed 600°C, causing the aluminum shell to melt and the resistance wire to fuse. The utility model installs a thermostat on the electric heating tube, and the thermostat controls the surface temperature of the electric heating tube to not exceed 550°C. The resistance wire is protected by a heat-resistant iron pipe, so that the life of the resistance wire is increased, the risk of aluminum shell melting is reduced, and the safety performance of the electric heating tube coil is improved.
[0013] The beneficial effect of the utility model is that an aluminum layer is arranged between the chassis and the electric heating tube. When the electric heating tube is working, the heat is first transferred to the aluminum layer, and then transferred to the chassis through the aluminum layer, thereby reducing the risk of the resistance wire melting due to the local rapid temperature rise of the chassis, thereby solving the risk of the resistance wire burning after the food is stuck to the bottom, improving safety, and also prolonging the life of the electric heating tube coil.
