Description

Technical Field

[0002] The current electric flame stoves directly discharge the working medium into the atmosphere, which will produce relatively serious ozone that harms the human body, and the direct discharge of the working medium into the atmosphere will cause a large amount of heat energy waste. Therefore, the patent with the authorization announcement number CN215723389U proposes a working medium internal circulation jet plasma stove, which relates to the field of plasma stove technology, including a stove shell and a plasma generator arranged on the stove shell, and a control module and a power module connected to the plasma generator; an impeller is arranged in the middle of the plasma generator, and a driving mechanism for driving the impeller to rotate is arranged at the lower end of the stove shell. A medium circulation mechanism is arranged inside the plasma generator, so that the working medium circulates in the furnace from beginning to end, and does not exchange with the outside atmosphere, thereby avoiding leakage and energy loss, and reducing the pollution of nitrogen oxide waste gas in the medium.

[0003] However, since the high temperature of the impeller is transmitted to the driving mechanism through the transmission shaft, the driving mechanism is easily overheated and burned. In addition, the internal circulation system and the heat dissipation system of the prior art are two independent systems, which not only increases the cost of the electric flame stove, but also increases the risk of failure.

[0004] The technical solution of the present invention is to utilize the airflow for dissipating heat from the power module to drive the driving mechanism, thereby solving the above-mentioned technical problem. Summary of the invention

[0007] Compared with the prior art, the advantages of the present invention are: The coupling of the internal circulation system and the heat dissipation system of the present invention solves the problem of the heat from the burner head being transferred through the transmission shaft to damage the drive motor in the existing internal circulation technology, and also suppresses the leakage of ozone generated by the electric flame stove to avoid the harm of ozone to the user or nearby human body, while reducing the loss of heat to the surrounding environment and improving the thermal efficiency; The coupling of the internal circulation system and the heat dissipation system avoids the need for multiple independent driving devices in the internal circulation system and the heat dissipation system in the prior art, making the electric flame stove structure more compact, reducing the risk of failure, and achieving efficient use of energy.

[0015] In addition, the technical features involved in the different embodiments of the present invention described later can be combined with each other as long as they do not conflict with each other.

[0016] See also Figure 1-2 In an embodiment of the present invention, an electric flame stove with a pneumatically driven internal circulation system includes: a stove body 100, a burner head 200 installed on the top surface of the stove body 100, a circuit module 300 installed in the stove body 100, a cooling blower 400 of a heat dissipation system installed on the stove body 100, and an internal circulation system. The internal circulation system includes a centrifugal fan 500 installed under the burner head 200 and an air suction fan 600 installed inside the burner head 200. Implementation Method 1

[0017] In this embodiment, the cooling blower 400 is connected to the airflow input end of the centrifugal fan 500 through the air duct, the air duct is in a contracted state at the part connected to the centrifugal fan 500, and the centrifugal fan 500 is provided with a radial impeller 501 inside, and the radial impeller 501 is coupled with the suction impeller 601 of the suction fan 600 through the transmission shaft 700; the airflow output end of the centrifugal fan 500 is connected to the heat dissipation air duct 900, and the heat dissipation air duct 900 is used to provide fast airflow for heat dissipation of the circuit module 300. Its working principle: After the cooling blower 400 is started, the airflow generated is transmitted to the airflow input end of the centrifugal fan 500 through the air duct. The air duct is contracted at the part connected to the centrifugal fan 500. When the airflow passes through, the flow velocity is accelerated and the energy is more concentrated to impact the radial impeller 501 inside the centrifugal fan 500, causing it to rotate. Under the impact of the airflow, the radial impeller 501 begins to rotate around its axis. At the same time, the radial impeller 501 is coupled with the suction impeller 601 of the suction fan 600 through the transmission shaft 700, so that the suction impeller 601 also rotates accordingly.

[0018] As the radial impeller 501 of the centrifugal fan 500 continues to rotate, the airflow is accelerated under the action of centrifugal force and introduced into the heat dissipation air duct 900 from the airflow output end of the centrifugal fan 500, and the airflow is discharged from the end of the heat dissipation air duct 900. The discharged airflow directly acts on the circuit module 300 to dissipate heat: when the airflow passes through the surface of the circuit module 300, heat exchange is performed between the airflow and the circuit module 300, and the heat generated during the operation of the circuit module 300 is taken away, thereby realizing the heat dissipation function of the circuit module 300.

[0019] The internal circulation system makes full use of the airflow energy generated by the cooling blower 400, and transmits the torque to the suction fan 600 through the transmission shaft 700, thereby solving the problem of the heat of the burner 200 being transmitted through the transmission shaft 700 and damaging the drive motor in the existing internal circulation technology. This energy transmission and utilization method also avoids the need for multiple independent drive devices in the internal circulation system and heat dissipation system of the prior art, thereby achieving efficient and diversified utilization of energy.

[0020] The internal circulation system is coupled with the heat dissipation system to make the electric flame stove structure more compact. Compared with multiple independent heat dissipation motor devices and internal circulation motor devices in the prior art, the present invention has a compact structure and reduces energy loss and failure risks that may be caused by scattered components.

[0021] The cooling blower 400 may be a high-power blower to meet the requirement of driving the internal circulation system. Implementation Method 2

[0022] The suction fan 600 is in operation, and its suction end is connected to the furnace 102 above the burner 200, and its outlet end is connected to the inside of the burner 200. Since the furnace 102 and the bottom of the cookware form a nearly closed space, when the suction fan 600 is in operation, the working medium gas in the furnace 102 is sucked in, and then the gas is sent back to the inside of the burner 200; at the same time, the ion generator 800 is installed in the burner 200, and its flame nozzle extends into the furnace 102. When the ion generator 800 is in operation, it obtains gas from at least one guide port 801 at the lower end (located in the burner 200), and after the internal action, the plasma flame is ejected from the flame nozzle to the furnace 102; after the plasma flame is heated and the heat energy is transferred to the cookware, it is sucked into the burner 200 again by the suction fan 600, thereby promoting the working medium gas to circulate inside the relatively closed burner 200 and the furnace 102.

[0023] The internal circulation system allows the working medium gas to circulate continuously between the inside of the burner head 200 and the inside of the furnace 102, reducing the loss of heat to the surrounding environment. The heat can be transferred to the pot more concentratedly to heat the objects inside. Compared with a system without internal circulation, this design can improve the heating speed and thermal efficiency of the pot under the same energy input, saving energy.

[0024] At the same time, the internal circulation system of the present invention also suppresses the ozone generated by the electric flame stove from leaking outwards, thereby preventing the ozone from causing harm to the user or nearby human bodies.

[0025] In the next embodiment, the transmission shaft 700 is sealed to the shell of the furnace head 200 to prevent the working medium from leaking out.

[0026] In the next embodiment, the cooling blower 400 is installed at the bottom of the stove body 100, and the stove body 100 is also provided with an exhaust grille 101 for discharging the gas after the heat is dissipated to the circuit module 300. The cooling blower 400 of the heat dissipation system inhales the cold air outside the bottom of the stove body 100, and the airflow works on the radial impeller 501, dissipates the heat of the circuit module 300, and is finally discharged from the exhaust grille 101. The airflow plays the role of driving the internal circulation system and the heat dissipation circuit module at the same time.

[0027] 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 present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
