All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a heating device, aiming at solving the problem that the service life of a heated body is seriously shortened because the flame of a gas burner in the prior art can not uniformly heat the heated body.

As shown in fig. 1 and 2, the apparatus includes a burner 10, a first electrode, a second electrode, a heat receiver 20, and an electric field generator 30, wherein the burner 10 is configured to mix a combustible gas with air and burn to generate a flame 11; the first electrode is arranged away from the burner 10 and on the side of the flame 11 generated by the burner 10; the second electrode is arranged close to the burner 10, and the flame 11 generated by the burner 10 is at least partially positioned between the first electrode and the second electrode; a first electrode is located between the heat receiver 20 and the burner 10, the heat receiver 20 being for receiving heat generated by the burner 10; the electric field generator 30 is electrically connected to the first electrode and the second electrode, and the electric field generator 30 is controlled to generate an electric field of a predetermined size between the first electrode and the second electrode, wherein the electric field is used for strengthening or suppressing the flame 11 generated by the burner 10.

The present application provides a heating device having an electric field generator 30, which controls the electric field to control the flame 11, thereby ensuring the heating uniformity of the heat receiver 20.

Specifically, since the flame 11 has the charged particles, in the combustion process of the flame 11, since the flame 11 has the charged particles, and the charged particles flow along with the ascending direction of the flame 11, after the electric field is applied to the flame 11, the electric field can control the movement of the charged particles in the flame 11, so as to strengthen or restrain the flame 11 generated by the burner 10, ensure that the flame 11 can uniformly heat the heat receiver 20, ensure the uniformity of heating of the heat receiver 20, further ensure that the cooked food can be cooked at the same time, avoid the phenomenon of mushy caused by the nonuniform heating of the heat receiver 20, improve the user experience of the heating device, and avoid the shortening of the service life of the heat receiver 20 due to the nonuniform heating for a long time.

As shown in fig. 1 and 2, the first electrode includes a conductive element 40, and the conductive element 40 is positioned above the flame 11 generated by the burner 10. In this way, the electric field generated between the conductive member 40 and the second electrode is ensured to be as parallel as possible to the direction in which the flame 11 rises, thereby ensuring that the electric field can effectively adjust the charged particles in the flame 11.

As shown in fig. 1, the conductive member 40 has a plate shape, and the area of the cross section of the conductive member 40 is greater than or equal to the area of the cross section at the nozzle position of the burner 10. In this way, it is ensured that the charged particles in the flame 11 are in the electric field generated between the conductive member 40 and the second electrode as much as possible, thereby ensuring the adjustment reliability of the electric field.

As shown in fig. 2, the conductive member 40 has a ring shape, and a projection of the conductive member 40 in the vertical direction is located on the outer peripheral side of the nozzle hole of the burner 10. In this way, it is ensured that the charged particles in the flame 11 are in the electric field generated between the conductive member 40 and the second electrode as much as possible, thereby ensuring the adjustment reliability of the electric field; in addition, the annular conductive member 40 can reduce consumables, thereby improving the economy of the heating apparatus.

Optionally, the conductive element 40 is movable relative to the flame 11 to change at least one of the profile and the direction of combustion of the flame 11.

It should be noted that, in the present application, the polarity of the first electrode and the polarity of the second electrode are opposite, and both the polarity of the first electrode and the polarity of the second electrode are adjustably set to change at least one of the profile and the combustion direction of the flame 11. In this way, the direction of the electric field is conveniently adjusted by adjusting the polarity of the first electrode and the polarity of the second electrode, so that at least one of the outline profile and the combustion direction of the flame 11 is changed, and the adjustment convenience of the heating device is improved.

In the present application, the degree of change in the profile of the flame 11 can also be adjusted by adjusting the intensity of the electric field.

In the present application, electric field generator 30 has a plurality of voltage value shifts, and the strength of the electric field differs for each voltage value shift. Therefore, the user can adjust the intensity of the electric field by adjusting the gears of different voltage values of the electric field generator 30, so as to change at least one of the outline and the burning direction of the flame 11, and the adjustment convenience of the heating device is greatly improved.

Optionally, the heating apparatus further includes a detection module and a control module, wherein the detection module is configured to detect heating information of the heat receiver 20; the control module controls the electric field generator 30 to provide an electric field of a preset intensity to the flame 11 according to the heating information. Thus, the intelligent degree of the heating device is improved.

It should be noted that, in the present application, the burner 10 has a conductive property, and the conductive element 40 is made of a high temperature resistant conductive material. In this way, failure of the conductive element 40 due to long-term exposure to high temperature environments is avoided.

Alternatively, the heat receiver 20 is plural, and the plural heat receivers 20 are disposed above the flame 11 at intervals. This ensures that the user can perform cooking work with a plurality of heat receivers 20 at the same time.

It should be noted that, in the present application, the heat receiver 20 may be a vessel for receiving food to be cooked, and may be a heat receiver, which is equivalent to a heat receiver, for intermediate heat exchange.

As shown in fig. 1, the heat receiver 20 and the conductive member 40 are disposed with a gap therebetween. Thus, when the heat receiver 20 is made of a metal material, there is a problem of safety hazard by avoiding direct contact between the heat receiver 20 and the conductive member 40.

In the present application, the material of the second electrode is the same as that of the burner 10, and the second electrode is integrally molded. In this way, the burner 10 is directly used as the second electrode, which is advantageous for simplifying the structure of the heating device.
