Description

Technical Field

[0001] This invention specifically relates to an electric flame stove. Background Technology

[0002] In today's society, electric flame cooktops are becoming increasingly popular and widely used as a fast and efficient cooking appliance. The working principle of an electric flame cooktop is mainly based on the formation of an electric arc through electrode electrical discharge, using the Joule heat of the arc to heat the cookware. However, the ozone problem generated when using traditional electric flame cooktops is gradually attracting attention. Ozone is a strong oxidant that is harmful to the human respiratory system and eyes; long-term exposure may lead to health problems.

[0003] Therefore, developing an electric flame stove that can eliminate or suppress ozone is a pressing technical challenge. For example, invention patent application CN111829022A discloses "an emission-suppressing plasma stove, comprising a base, a stove head mounted on the base, and an electronic control unit mounted on the base. The stove head includes multiple discharge electrodes exposed above the base and a transformer module disposed below the discharge electrodes. The transformer module includes a mounting housing mounted on the base and a transformer circuit unit disposed within the mounting housing. The transformer circuit unit is electrically connected to the electronic control unit and the discharge electrodes. The stove head also includes a part sealed to the upper end of the mounting housing." The invention includes a high-temperature and high-pressure resistant insulating plate for mounting the multiple discharge electrodes, and a cylindrical support ring protruding above the base and surrounding the discharge electrodes. The cylindrical support ring supports the cookware and, together with the high-temperature and high-pressure resistant insulating plate and the bottom of the cookware, forms a sealed inner cavity for the stove head. The high-temperature and high-pressure resistant insulating plate and the mounting housing are provided with an exhaust channel communicating with the inner cavity of the stove head. The exhaust channel is connected to an exhaust fan electrically connected to the electronic control unit outside the mounting housing. The exhaust fan draws air into the inner cavity of the stove head to a negative pressure state at the initial stage of ignition and removes the emissions from the inner cavity of the stove head after the stove is turned off. This invention uses an exhaust fan in the cylindrical support ring to remove ozone generated by electrode discharge, but this can only be done at the initial stage of ignition or after the stove is turned off. However, in actual use, the plasma stove involves long cooking times, during which the electrode discharge continuously generates ozone, seriously affecting people's health. In addition, the high-temperature plasma generated by the electric arc formed by the electrode discharge can even exceed 1000 degrees Celsius, and even at the initial stage of ignition or after the stove is turned off, the exhaust fan cannot withstand such high temperatures.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Please see Figures 1-5 In this embodiment of the invention, an ozone-suppressing electric flame stove includes: a burner head 1, comprising an upper shell 11, a plurality of negative electrode flame tubes 111 disposed on the upper shell 11, a lower shell 12, a plurality of insulating cyclones 121 disposed on the lower shell 12, and a positive electrode needle 122 disposed in the middle of a single insulating cyclone 121; a stove box 2, comprising a panel 21 and a base 22, the base 22 being provided with a drive circuit 224, a transformer circuit 221, and a rectifier circuit 222 electrically connected to the positive electrode needle 122; and an ejector 3 disposed on the burner head 1, the ejector 3 being connected to hydrogen gas through a conduit 32 and an electric valve 33, the ejector 3 also being provided with a plurality of injection holes 31 for injecting hydrogen gas.

[0029] Panel 21 is equipped with an adjustment switch knob 211 and a control circuit 212 controlled by the adjustment switch knob 211. The control circuit 212 is electrically connected to and controls a relay 223 and a drive circuit 224. The relay 223 is electrically connected to and controls an electric valve 33. An insulated cyclone separator 121 and a negative electrode flame tube 111 are fixedly connected to form a sealed space for generating high-temperature plasma by electric shock from the positive electrode needle 122. Rotating the adjustment switch knob 211 adjusts the control circuit 212, which in turn controls the drive circuit 224 to supply the required drive power to the transformer circuit 221 and controls the conduction, shutdown, and output power of the transformer circuit 221. The transformer circuit 221 converts the low-voltage electricity from the drive circuit 224 into high-voltage electricity and outputs it to the rectifier circuit 222. The rectifier circuit 222 then distributes the high-voltage electricity to multiple positive electrode needles 122. The positive electrode needles 122 discharge to the negative electrode flame tube 111 to form an electric arc and generate high-temperature plasma.

[0030] The upper shell 11 and the lower shell 12 are fixedly connected by screws to form a sealed box. The lower shell 12 is also equipped with an air intake fan 123. The side wall of the insulating cyclone separator 121 has an inclined air intake hole 124 for generating a rotating outer ring airflow. The negative electrode flame tube 111 is conical in shape. While the positive electrode needle 122 discharges, the air intake fan 123 generates airflow for the sealed box. The airflow enters the interior of the insulating cyclone separator 121 through the air intake hole 124 and forms a vortex outer ring airflow. The vortex outer ring airflow protects the electric arc and drives the plasma to rotate and move upward. Due to the conical design of the negative electrode flame tube 111, the rotating plasma airflow is compressed upward, causing the airflow to accelerate, thereby causing the high-temperature plasma to be quickly ejected from the negative electrode flame tube 111, effectively heating the pot.

[0031] In this embodiment, the discharge of the positive electrode needle 122 causes a chemical change in the oxygen in the gas flow, generating oxygen. Simultaneously, the control circuit 212 controls the electric valve 33 to open via the relay 223, allowing a small amount of hydrogen to be released. The hydrogen passes through the conduit 32 to the ejector 3 and is sprayed into the inner cavity of the support ring 112 through the injection hole 31. The mixture of hydrogen and air undergoes a chemical change upon encountering high temperature, i.e., combustion. This combustion causes the hydrogen to react with the ozone or oxygen in the inner cavity of the support ring 112 to generate water vapor, thereby suppressing ozone emissions. Since ozone is a strong oxidant, a small amount of hydrogen can be added to burn, and the combustion provides a better heating effect for the electric flame stove.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
