Description

Technical Field

[0001] The utility model relates to a combined variable voltage and mutual inductance device, in particular to the field of electric flame stoves. Background Art

[0002] In the existing electric flame stove, the furnace head fan adopts a constant power supply voltage. No matter the load size of the anode needle and the temperature, the rotation speed of the fan always remains unchanged. However, in the state of constant high rotation speed of the fan, when the "firepower" is small, the large air flow is likely to affect the normal generation of plasma and the normal performance of the electric flame stove; while in the state of constant high rotation speed of the fan, when the "firepower" is large, the small air flow is not enough to have enough gas to be ionized, and at the same time, the ionized plasma is not ejected from the flame tube in time to heat the cookware, resulting in energy waste and overheating of the furnace head, shortening the service life of the furnace head.

[0021] 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.

[0022] Please refer to Figure 1 , in the embodiment of the present utility model, a combined transformer and mutual inductor device includes: a base 1, a transformer 2 installed on the base 1, and a mutual inductor 3; the transformer 2 includes a magnetic core assembly 21, a first coil 22, and a second coil 23. The first coil 22 and the second coil 23 are respectively wound around a first insulating cylinder 24 and a second insulating cylinder 25, and the first insulating cylinder 24 and the second insulating cylinder 25 are respectively sleeved on both ends of the magnetic core assembly 21; one end lead of the first coil 22 passes through the inner ring of the mutual inductor 3.

[0023] The technical solution of the present utility model integrates the transformer 2 and the mutual inductor 3 into a combined transformer and mutual inductor device, which has high energy transmission efficiency and low manufacturing cost.

[0024] Among them, the first coil 22 is connected to the control circuit of the electric flame stove, the second coil 23 is connected to the electrode assembly of the electric flame stove, and the output end of the mutual inductor 3 is connected to the stove head fan of the electric flame stove. The user can adjust the power input to the first coil 22 by manipulating the control circuit.

[0025] When current passes through the first coil 22, a magnetic field is generated and passes through the magnetic core assembly 21 and is transmitted to the second coil 23. The second coil 23 has multiple turns, and the magnetic field induced by the second coil 23 will generate a high-voltage current. Since the second coil 23 is connected to the electrode assembly of the electric flame stove, the user can directly control the power of the electrode assembly by manipulating the control circuit to adjust the power input to the first coil 22.

[0026] At the same time, when current passes through one end lead of the first coil 22, the mutual inductor 3 generates a mutual inductance current, and the power of this mutual inductance current changes with the output power of the control circuit. Since the output end of the mutual inductor 3 is connected to the stove head fan of the electric flame stove, the user can directly control and synchronously control the rotation speed of the fan by manipulating the control circuit to adjust the power input to the first coil 22.

[0027] The magnetic core assembly 21 includes a symmetric first U-shaped magnetic core 211 and a second U-shaped magnetic core 212.

[0028] The first U-shaped magnetic core 211 and the second U-shaped magnetic core 212 are fixedly connected by a linear fixing member 4, and the fixing member 4 is made of an insulating material.

[0029] The first insulating cylinder 24 and the second insulating cylinder 25 are fixed on the base 1 by an adhesive.

[0030] An electric flame stove includes the combined transformer and mutual inductor device of any one of the above. Through the combined transformer and mutual inductor device, the power of the electrode assembly is synchronized with the rotation speed of the stove head fan, ensuring that the arc of the electrode assembly is not affected by the wind speed in the low-power state and reducing the generation of noise. When the electrode assembly is in the high-power state, the plasma flame can fully eject from the stove head to heat the cookware.

[0031] 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-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to encompass all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
