[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.

[0025] In addition, the technical features involved in different embodiments of the present utility model described subsequently can be combined with each other as long as they do not conflict with each other.

[0026] Please refer to Figures 1 to 2 , in the embodiment of the present utility model, an electric flame stove with a pneumatic drive 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 the heat dissipation system installed on the stove body 100, and an internal circulation system. Among them, the internal circulation system includes a centrifugal blower 500 installed below the burner head 200 and a suction blower 600 installed inside the burner head 200.

[0027] Embodiment 1

[0028] In this embodiment, the cooling blower 400 is connected to the air flow input end of the centrifugal ventilator 500 through a duct. The part of the duct connected to the centrifugal ventilator 500 is in a contracted shape. Inside the centrifugal ventilator 500, there is a radial impeller 501. The radial impeller 501 is drivingly coupled to the suction impeller 601 of the suction ventilator 600 through a transmission shaft 700. The air flow output end of the centrifugal ventilator 500 is connected to a heat dissipation air duct 900, and the heat dissipation air duct 900 is used to provide a fast air flow for dissipating heat from the circuit module 300. Its working principle is as follows:

[0029] After the cooling blower 400 is started, the air flow generated is transmitted through the duct to the air flow input end of the centrifugal ventilator 500. The part of the duct connected to the centrifugal ventilator 500 is in a contracted shape. When the air flow passes through, the flow rate increases and the energy is more concentrated to impact the radial impeller 501 inside the centrifugal ventilator 500, causing it to rotate. Under the impact of the air flow, the radial impeller 501 starts to rotate around its axis. At the same time, the radial impeller 501 is drivingly coupled to the suction impeller 601 of the suction ventilator 600 through the transmission shaft 700, causing the suction impeller 601 to rotate accordingly.

[0030] As the radial impeller 501 of the centrifugal ventilator 500 continues to rotate, the air flow is accelerated under the action of centrifugal force and is introduced into the heat dissipation air duct 900 from the air flow output end of the centrifugal ventilator 500, and the air flow is discharged from the end of the heat dissipation air duct 900. The discharged air flow directly acts on the heat dissipation of the circuit module 300: when the air flow passes through the surface of the circuit module 300, heat exchange occurs between the air flow and the circuit module 300, taking away the heat generated during the operation of the circuit module 300, thereby realizing the heat dissipation function of the circuit module 300.

[0031] The internal circulation system makes full use of the air flow energy generated by the cooling blower 400, and transmits the torque to the suction ventilator 600 through the transmission shaft 700, solving the problem that the heat of the burner head 200 in the existing internal circulation technology is transmitted through the transmission shaft 700 and damages the driving motor. This way of energy transmission and utilization also avoids the need for multiple independent driving devices in the existing internal circulation system and heat dissipation system, realizing the efficient and diversified utilization of energy.

[0032] The internal circulation system is coupled with the heat dissipation system, making the structure of the electric flame stove more compact. Compared with the existing technology with multiple independent heat dissipation motor devices and internal circulation motor devices, the utility model has a compact structure and reduces the energy loss and failure risk caused by the dispersion of components.

[0033] The cooling blower 400 can select a high-power blower to meet the requirement of driving the internal circulation system.

[0034] Embodiment 2

[0035] The suction ventilator 600 comes into play. Its suction end is connected to the furnace chamber 102 above the burner head 200, and the outlet end is connected to the inside of the burner head 200. Since an almost enclosed space is formed between the furnace chamber 102 and the bottom of the cookware, when the suction ventilator 600 operates, it will suck in the working medium gas in the furnace chamber 102 and then send these gases back into the burner head 200. At the same time, the ion generator 800 is installed inside the burner head 200, and its flame ejection port extends into the furnace chamber 102. During operation, the ion generator 800 obtains gas from at least one diversion port 801 at the lower end (inside the burner head 200), and after internal action, ejects a plasma flame from the flame ejection port into the furnace chamber 102. After the plasma flame heats and transfers heat energy to the cookware, it is sucked back into the burner head 200 by the suction ventilator 600 again, thus promoting the internal circulation of the working medium gas within this relatively enclosed burner head 200 and furnace chamber 102.

[0036] The internal circulation system enables the working medium gas to continuously circulate between the inside of the burner head 200 and the inside of the furnace chamber 102, reducing the loss of heat to the surrounding environment. The heat can be more concentratedly transferred to the cookware for heating the objects therein. Compared with a system without internal circulation, this design can increase the heating speed and thermal efficiency of the cookware under the same energy input, saving energy.

[0037] At the same time, the internal circulation system of the present utility model also inhibits the external leakage of ozone generated by the electric flame stove, avoiding harm to users or nearby people caused by ozone.

[0038] In the next embodiment, the transmission shaft 700 is hermetically connected to the housing of the burner head 200 to prevent the leakage of the working medium.

[0039] 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 cooling the circuit module 300. The cooling blower 400 of the heat dissipation system sucks in the cold air outside the bottom of the stove body 100. After the air flow does work on the radial impeller 501, it dissipates heat from the circuit module 300 and finally discharges from the exhaust grille 101. The air flow also plays the role of driving the internal circulation system and dissipating heat from the circuit module.

[0040] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
