Description

Technical Field

[0001] This utility model relates to stoves, and more particularly to an electric flame burner head that can suppress ozone and an electric flame stove having the same. Background Technology

[0002] An electric flame stove is a type of open-flame stove that does not use chemical fuels; it can also be described as a device that ignites air. An electric flame stove generates a strong electric field between one or more pairs of electrodes by applying a high-voltage pulse power supply. This ionizes and heats the air flowing between the electrodes, transforming it into a high-temperature plasma stream. This plasma stream heats the cookware with a visible flame effect similar to that of a gas stove.

[0003] Electric flame stoves, as a novel application of electric arc plasma, have many unique advantages. However, due to the inherent characteristics of air plasma, they also have side effects. For example, the plasma gas stream generated by the arc discharge contains ozone and nitrogen oxides of varying densities. This is because the temperature is highest near the anode, making it very easy to generate ozone. Additionally, with prolonged use, the electrode surface is prone to ablation, and the ablated electrode is more susceptible to corona discharge, further generating ozone. Ozone production then leads to the production of even more nitrogen oxides. Excessive emissions of ozone and nitrogen oxides can potentially harm human health. Utility Model Content

[0051] The ozone-suppressing electric flame burner and the electric flame stove having it are described in detail below with reference to the accompanying drawings.

[0052] Reference Figures 1 to 5 As shown, the ozone-suppressing electric flame burner head provided according to an embodiment of the present invention includes a panel 10 and a plasma electrode assembly 30.

[0053] Specifically, the panel 10 is provided with an electrode sleeve 101, the upper end of which has a flame port H101. The flame port H101 serves to guide the flame and control the flame jet position. Exemplarily, there are usually multiple electrode sleeves 101, arranged in an array on the panel 10. For example, multiple electrode sleeves 101 can be arranged in a circular array, forming multiple ignition points to achieve uniform heating. Preferably, the electrode sleeve 101 and the panel 10 are made of the same material (e.g., stainless steel) and are formed as a single unit.

[0054] A plasma electrode assembly 30 is disposed within the electrode sheath 101. The plasma electrode assembly 30 includes an anode 301 and a cathode 302, and a nanoscale coating is formed on the surface of the anode 301 and / or the cathode 302. In specific applications, the plasma electrode assembly 30 is connected to a high-voltage pulse drive power supply. The high-voltage pulse drive power supply provides a high-voltage pulse, which generates a strong electric field when the high-voltage pulse is applied to the anode 301 and the cathode 302. This ionizes and heats the air flowing between the anode 301 and the cathode 302, transforming it into a high-temperature plasma gas flow, forming an electric flame. The nanoscale coating can be formed using processes such as vapor deposition and electrochemical methods.

[0055] The nanoscale coating includes at least a titanium dioxide (TiO2) layer to isolate and protect the anode 301 and / or cathode 302, and to degrade ozone and nitrogen oxides in the plasma flame.

[0056] The titanium dioxide layer is uniformly formed on the surface of the anode 301 and / or the cathode 302. The titanium dioxide layer provides excellent insulation and protection, reducing electrode ablation caused by prolonged high-temperature discharge, thereby reducing ozone generation. Simultaneously, as a photocatalyst, titanium dioxide can be activated above 600°C, forming a photocatalytic reaction. This reaction helps degrade ozone and nitrogen oxides generated in the plasma flame, effectively reducing the concentration of harmful gases during the discharge process.

[0057] According to the ozone-suppressing electric flame burner head provided in this embodiment of the present invention, by forming a nano-scale titanium dioxide coating on the surface of the plasma electrode assembly 30 (including the anode 301 and the cathode 302) of the electric flame burner head, the electrode is isolated and protected, and ozone and nitrogen oxides in the plasma flame are degraded. Thus, while maintaining the high-efficiency heating performance of the electric arc plasma flame, the generation and emission of harmful gases are effectively reduced, and the safety of use is improved.

[0058] In one embodiment of this invention, the nanoscale coating further includes an aluminum oxide layer formed on the surface of the anode 301 and / or cathode 302 to isolate and protect the anode 301 and / or cathode 302, and a titanium dioxide layer formed on the surface of the aluminum oxide layer. Preferably, the thickness of the aluminum oxide layer is 50 to 100 nm, and the thickness of the titanium dioxide layer is 60 to 100 nm.

[0059] The aluminum oxide layer has good high temperature resistance and corrosion resistance, which can effectively isolate the electrode material from direct contact with the external environment, prevent the electrode material from being burned or degraded due to long-term high voltage and high temperature operation, and significantly improve the electrode's resistance to burning and degradation and its service life.

[0060] In the manufacturing process, the anode 301 and the cathode 302 can be formed by processing pure copper or copper material. First, an aluminum oxide layer (Al2O3) is deposited on the surface of the anode 301 and the cathode 302, and then a titanium dioxide layer (TiO2) is deposited.

[0061] The two-step deposition process described above forms an aluminum oxide layer and a titanium dioxide layer, constituting a composite nanoscale coating. This composite coating fully utilizes the advantages of each material, ensuring excellent high-temperature and corrosion resistance of the electrode under high-temperature and high-voltage discharge environments, reducing electrode ablation after prolonged use, and thus inhibiting the generation of ozone and nitrogen oxides. Simultaneously, it utilizes the photocatalytic effect of titanium dioxide to degrade ozone and nitrogen oxides, thereby achieving dual protection for the electrode and its discharge area in the electric flame furnace head, significantly improving the ozone suppression effect.

[0062] Reference Figures 2 to 5 As shown, in one embodiment of this utility model, the anode member 301 is a columnar member, and the cathode member 302 is a spiral member. The columnar member is inserted into the spiral member and the two are arranged coaxially.

[0063] In other words, the anode 301 adopts a columnar design, such as a cylindrical shape, to ensure high structural stability and heat resistance under high-speed discharge and high-temperature environments. The cathode 302 adopts a spiral coil structure design. This spiral coil is composed of several coiled conductive materials, which ensures sufficient discharge area and facilitates the formation of a uniformly distributed electric field. The spiral coil structure can also significantly enhance the local electric field strength during discharge, improve air ionization efficiency, and thus form a stable and efficient plasma flame.

[0064] Furthermore, the columnar anode 301 is inserted inside the spiral-shaped cathode 302, and the two are arranged coaxially. This coaxial arrangement not only ensures the symmetry and uniformity of the discharge region, but also effectively reduces the distance between the electrodes, lowers the energy consumption of the arc discharge, and improves plasma excitation and transport efficiency.

[0065] In this embodiment, by designing the anode 301 as a columnar part and the cathode 302 as a spiral coil part, and adopting a through-and coaxial arrangement structure, the uniformity of the electric field distribution and air ionization efficiency in the discharge area are significantly improved, ensuring the stability and high-efficiency heating performance of the plasma flame.

[0066] Reference Figure 5As shown, in one embodiment of the present invention, the surface of the columnar member is provided with a plurality of spiral patterns 3011, the plurality of spiral patterns 3011 are arranged at intervals along the circumference of the columnar member, one end of each spiral pattern 3011 starts at the lower end of the columnar member, and the other end of the spiral pattern 3011 ends at the upper end of the columnar member.

[0067] By designing multiple uniformly distributed spiral patterns 3011 on the surface of the columnar component, and making each spiral pattern 3011 start from the bottom end of the columnar component and end at the top end, not only is the coating deposition area increased and the degradation ability improved, but the stability and heating efficiency of the plasma flame are further improved by improving the uniformity of airflow distribution and micro-electric field distribution.

[0068] Reference Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments of the present invention, the ozone-suppressing electric flame burner head further includes a support plate 20, which is located below the panel 10 and defines an air cavity between the support plate 20 and the panel 10.

[0069] A fan 40 is provided at the bottom of the tray 20 to supply air into the air cavity and allow the air to flow through the air cavity into the electrode sheath 101 to cool the plasma electrode assembly 30.

[0070] In this embodiment, a fan 40 blows air into the air cavity, which then flows into the electrode sheath 101 and is ejected from the flame port H101 of the electrode sheath 101. During this process, the incoming cold air cools the plasma electrode assembly 30 inside the electrode sheath 101, preventing it from becoming too hot. Excessive heat would lead to the generation of large amounts of ozone, and the real-time cooling effect of the fan 40 can suppress a significant temperature increase to some extent. Thus, the generation of ozone and nitrogen oxides can be reduced at lower temperatures, further improving environmental friendliness and safety.

[0071] Reference Figures 2 to 4 As shown, in one embodiment of this utility model, an electrode holder 31 is provided inside the air cavity. The anode element 301 passes through the center of the electrode holder 31, and the cathode element 302 is coaxially sleeved outside the anode element 301 and fixed to the electrode holder 31. By providing an electrode holder 31 inside the air cavity and coaxially mounting the anode element 301 and the cathode element 302 on it, the stable fixation of the plasma electrode assembly 30 is effectively achieved.

[0072] In one embodiment of this utility model, the electrode holder 31 includes an electrode base 311 and an electrode top seat 312. The electrode base 311 is fixed on the support plate 20 and has a first through hole H3a. The electrode top seat 312 is pluggably connected to the electrode base 311. That is, the electrode top seat 312 and the electrode base 311 are connected by a pluggable connection, which facilitates assembly, maintenance, and replacement.

[0073] The electrode top seat 312 has a second through hole H3b and a third through hole H3c arranged coaxially, the diameter of the third through hole H3c being smaller than the diameter of the second through hole H3b. The anode member 301 passes through the third through hole H3c, and the lower end of the anode member 301 is inserted into the first through hole H3a. The cathode member 302 is sleeved in the second through hole H3b.

[0074] In the specific assembly process, the anode component 301 can be inserted into the third through hole H3c first, and then the cathode component 302 can be inserted into the second through hole H3b, so that the anode component 301 and the cathode component 302 can be installed on the electrode top seat 312. Then the electrode top seat 312 is inserted into the electrode base 311, while ensuring that the lower end of the anode component 301 is inserted into the first through hole H3a of the electrode base 311. Finally, the panel 10 and the support plate 20 are combined together to complete the assembly of the entire furnace head.

[0075] With the above structure, the electrode base 311 and the electrode top seat 312 are plugged in and plugged in, and the anode 301 and cathode 302 can also be plugged into the electrode top seat 312. This allows for quick assembly of the components and facilitates maintenance and replacement. Furthermore, it ensures coaxial mounting of the anode 301 and cathode 302, thereby guaranteeing the uniformity and stability of the electric flame generated by the plasma electrode assembly 30.

[0076] Preferably, a sealing gasket is provided between the panel 10 and the tray 20, which can improve the sealing performance between the panel 10 and the tray 20.

[0077] Reference Figure 6 As shown, this utility model embodiment also provides an electric flame stove with an electric flame burner head that can suppress ozone as described in the above embodiment.

[0078] According to the electric flame stove provided in this embodiment of the present invention, by forming a nano-scale titanium dioxide coating on the surface of the plasma electrode assembly 30 (including the anode 301 and the cathode 302) of the electric flame burner head, the electrode is isolated and protected, and ozone and nitrogen oxides in the plasma flame are degraded. Thus, while maintaining the high-efficiency heating performance of the electric arc plasma flame, the generation and emission of harmful gases are effectively reduced, and the safety of use is improved.
