Description

Technical Field

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

[0002] The electric flame stove adopts a structure in which multiple sets of high-voltage discharge devices are arranged in parallel with positive and negative electrodes in the air. It relies on the high-voltage electric field to break down the flowing air. The air molecules collide with the high-speed electrons in the electric field and ionize, thereby generating high-temperature plasma. The high temperature of the plasma of more than 1,000 degrees Celsius is used to heat the cookware. Similar products on the market are also called electric fire stoves, electric fire stoves, plasma open flame stoves, etc., all of which use the core heating principle of high-voltage ionization to generate gas plasma.

[0003] During the operation of existing electric flame stoves, the air outlet of the cooling fan covers a wide area and does not specifically target the heat-generating components (control circuit board, driver chip, transformer, rectifier diode, etc.) that need cooling. Although significantly increasing the speed of the cooling fan can effectively cool the heat-generating components, the cooling fan becomes the main source of noise. The noise is mainly divided into two categories: first, the aerodynamic noise and mechanical noise generated by the operation of the fan motor and the high-speed rotation of the impeller; second, the vibration force generated by the fan operation is transmitted to the stove body and burner shell, causing the shell to resonate and deform, generating secondary vibration noise. Overall, the operating noise is relatively high.

[0004] The noise generated by electric flame stoves leads to a poor user experience. At the same time, long-term resonance can cause internal wiring to loosen and discharge components to shift, affecting the lifespan and operational stability of the equipment. Summary of the Invention

[0005] To overcome the shortcomings mentioned above, the present invention aims to provide a technical solution that can solve the above problems.

[0006] An energy-saving and noise-reducing electric flame stove includes: a stove body, a burner discharge assembly, a high-voltage power supply module, and a heat dissipation assembly; the high-voltage power supply module includes a high-voltage transformer, a power drive device, and a rectifier filter element. The burner head discharge assembly is assembled in the upper part of the stove body, and the high-voltage power supply module is installed in the internal cavity of the stove body; The heat dissipation assembly includes a silent heat dissipation fan, a directional air duct, and a shock-absorbing support. The silent heat dissipation fan is fixed to one side of the inside of the stove body by the shock-absorbing support, and the air inlet of the silent heat dissipation fan is connected to the outside of the stove body. One end of the directional air duct is connected to the air outlet of the silent heat dissipation fan, and the other end of the directional air duct branches to form multiple sets of air guide nozzles with constricted openings. The constricted openings of each set of air guide nozzles point to the high-voltage transformer, power drive device, and rectifier filter element respectively. The silent cooling fan is a low-power, low-speed fan that always maintains a low-speed constant working state, with a working speed in the range of 800 to 1500 r / min. Preferably, the directional airflow duct is integrally molded from rigid heat-insulating plastic material, and the inner wall of the directional airflow duct is designed with a smooth streamlined structure. Preferably, the shock-absorbing support is an integrated high-elasticity rubber structure, and the silent cooling fan is completely suspended through the shock-absorbing support. Preferably, the converging opening of each group of air guide nozzles has a small converging structure, so that the air outlet of the air duct forms a focused and directional airflow, which is precisely aimed at the surface of each heat-generating component for targeted heat dissipation. Preferably, the directional airflow duct is assembled by combining upper and lower parts and fastening them with bolts; Preferably, the specific manufacturing method of the directional airflow duct is as follows: Based on the internal installation space of the electric flame stove, the size of the fan outlet, and the distribution parameters of the heating points of each component, molds for the upper and lower parts of the air duct are designed separately. The mold for the upper part of the air duct is reserved for the upper nozzle shell structure, and the mold for the lower part of the air duct is reserved for the lower nozzle shell structure corresponding to the upper nozzle structure. The molds for the upper and lower sections of the air duct are respectively subjected to hot melt injection molding. After the injection molded part cools and is demolded, and the flash and burrs on the surface of the component are removed, the upper and lower air ducts that have been formed are precisely aligned and attached to form a complete ventilation channel. The corresponding upper and lower nozzle shell structures are then combined to form a complete air guide. Bolts are inserted into the mounting lugs of the upper and lower duct sections and locked in place to form a complete directional airflow duct.

[0007] Compared with the prior art, the advantages of the present invention are: This invention abandons the traditional design of electric flame stoves that rely on high-speed fan rotation, dispersed airflow, and wide-area heat dissipation coverage. Instead, it utilizes a branched air guide structure with a converging nozzle to converge and concentrate the dispersed airflow output from a low-speed, silent cooling fan, forming a high-pressure, highly concentrated directional cooling airflow. This airflow precisely targets the high-voltage transformer, power drive devices, rectifier filter components, and all core heat-generating components on the control board, significantly improving cold air utilization and ensuring that the temperature of each heat-generating component remains within a safe operating range even under low-speed fan operation. The significantly improved cooling efficiency allows the silent cooling fan to operate at a low speed, drastically reducing aerodynamic noise from the high-speed fan impeller and mechanical noise from the motor, completely avoiding the high noise problem associated with traditional high-speed fans. Furthermore, this silent cooling fan operates at a constant low speed throughout, without high-speed, high-load operation, significantly reducing fan power consumption, minimizing energy loss, and achieving energy savings.

[0008] The silent cooling fan of this invention is suspended in the air by a high-elasticity rubber shock-absorbing support, which completely isolates the transmission path of the fan's vibration to the stove body shell, eliminates secondary vibration noise caused by shell resonance deformation, greatly improves the overall noise reduction effect, and effectively improves the user experience.

[0009] This directional airflow duct is assembled by combining the upper and lower duct sections and fastening them with bolts. Its individual parts are simple to form, the molds are universal, and the yield rate is high, which greatly reduces the overall production and manufacturing cost of the duct.

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0016] Furthermore, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. 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.

[0017] 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.

[0018] Please see Figures 1-2 In this embodiment of the invention, an energy-saving and noise-reducing electric flame stove includes: a stove body 1, a burner discharge assembly 2, a high-voltage power supply module 3, and a heat dissipation assembly; the high-voltage power supply module 3 includes a high-voltage transformer, a power drive device, and a rectifier filter element.

[0019] The burner head discharge assembly 2 is installed in the upper part of the stove body 1. It is used to generate plasma high-temperature open flame by high-voltage ionization of air to heat the cookware. The high-voltage power supply module 3 is fixed in the internal cavity of the stove body 1 to provide high-frequency high-voltage power supply to the burner head discharge assembly 2. It will continuously generate working heat during operation and is the main heat source of the whole machine.

[0020] The heat dissipation components include a silent heat dissipation fan 41, a directional air duct 42, and a shock-absorbing support 43. The silent heat dissipation fan 41 is fixed to one side inside the stove body 1 through the shock-absorbing support 43, and the air inlet of the silent heat dissipation fan 41 is connected to the outside of the stove body 1.

[0021] The core improvement of this invention lies in the fact that one end of the directional airflow duct 42 is sealed and connected to the air outlet of the silent cooling fan 41, and the other end of the directional airflow duct 42 branches to form multiple sets of air guide nozzles 420 with converging openings 4200. The converging openings 4200 of each set of air guide nozzles 420 are respectively directed to high-heat-generating components such as high-voltage transformers, power drive devices, rectifier filter elements, and control motherboards. The converging openings 4200 of each set of air guide nozzles 420 have a small-mouth convergent structure, so that the air outlet of the directional airflow duct 42 forms a concentrated directional airflow, which accurately targets the surface of each heat-generating component for point-to-point heat dissipation.

[0022] The 4200 retractable nozzle can converge, accelerate, and pressurize the gentle, dispersed airflow output by a low-speed fan, transforming the originally limited and highly diffused low-speed airflow into a high-velocity, highly concentrated directional cooling airflow, maximizing the utilization of cold air and precisely targeting the heat source. It can quickly remove the heat accumulated in various components without the need for the fan to run at high speed.

[0023] It is important to emphasize that, through this principle of concentrated air pressure and fixed-point heat dissipation, the silent cooling fan 41 can operate stably in the low-speed range of 800-1500 r / min for a long time, without high-speed and high-load operation conditions. This significantly reduces the fan's operating power consumption, effectively reduces energy loss, and achieves good energy-saving effects. In addition, the aerodynamic noise and motor mechanical noise generated by the silent cooling fan 41 under low-speed conditions completely solve the problem of excessive noise caused by traditional electric flame stoves relying on high-speed fans for heat dissipation. The overall quietness of the machine is significantly improved, while the fan's operating power consumption is greatly reduced, energy loss is reduced, and energy-saving effects are achieved.

[0024] In a specific embodiment of the present invention, the silent cooling fan 41 is a low-power, low-speed fan that always maintains a low-speed constant working state, with a working speed in the range of 800 to 1500 r / min.

[0025] In a specific embodiment of the present invention, the directional airflow duct 42 is integrally molded from rigid heat-insulating plastic material. The inner wall of the directional airflow duct 42 adopts a smooth streamlined structure, which can minimize wind resistance and turbulence noise during airflow transportation, making low-speed airflow transportation smoother and more stable, and avoiding additional wind noise generated inside the duct. The shock-absorbing support 43 is an integral high-elasticity rubber structure. The silent heat dissipation fan 41 is completely suspended through the shock-absorbing support 43, completely isolating the transmission path of fan operation vibration to the stove body 1 shell, and eliminating secondary vibration noise generated by shell resonance deformation.

[0026] Through the above-mentioned structural combination, the present invention successfully achieves the technical goals of low-speed heat dissipation, high-efficiency cooling, ultra-low noise, and energy saving without reducing heat dissipation performance or affecting the normal heating operation of the electric flame stove. It solves the problems of high noise, severe resonance, high energy consumption, and poor stability of existing electric flame stoves.

[0027] In a specific embodiment of the present invention, the directional airflow duct 42 is assembled by combining and bolting an upper duct section 421 and a lower duct section 422. The specific manufacturing method is as follows: Based on the internal installation space of the electric flame stove, the size of the fan outlet, and the distribution parameters of the heating points of each component, molds for the upper split 421 and the lower split 422 of the air duct are designed separately. The mold for the upper split 421 of the air duct is reserved for the upper nozzle shell structure 4201, and the mold for the lower split 422 of the air duct is reserved for the lower nozzle shell structure 4202 corresponding to the upper nozzle structure. The molds for the upper split part 421 and the lower split part 422 of the air duct are respectively subjected to hot melt injection molding. After the injection molded part is cooled and demolded and the flash and burrs on the surface of the component are removed, the formed upper air duct 421 and lower air duct 422 are precisely aligned and attached to form a complete ventilation channel. The corresponding upper nozzle shell structure 4201 and lower nozzle shell structure 4202 are combined to form a complete air guide nozzle 420. Bolts are inserted into the mounting lugs of the upper duct section 421 and the lower duct section 422 to lock and fix them, forming a complete directional airflow duct 42.

[0028] The split structure of the aforementioned directional air duct 42 is simple to form, uses universal molds, and has a high yield rate, which greatly reduces the overall production and manufacturing cost of the air duct.

[0029] 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.
