[0022] In addition, the technical features involved in the different embodiments of the utility model described subsequently can be combined with each other as long as they do not conflict with each other.

[0023] Please refer to Figure 1 In the utility model embodiment, an ozone-overflow-preventing electric flame range comprises a range body 1, a hearth 2, an air suction device 3 and a plurality of plasma burners 4 arranged in the hearth 2, and a through hole 11 is arranged on the panel of the range body 1;

[0024] In the embodiment, the air suction device 3 is arranged in the range body 1 below the panel, and it is arranged in a circumferential direction around the through hole 11 to form an annular structure, and an annular air duct is arranged in the cavity of the air suction device 3; the hearth 2 is arranged in the annular inner wall of the air suction device 3, and the annular inner wall of the air suction device 3 is provided with a plurality of air suction grooves 31; and the air suction device 3 is connected to an air extractor outside the range body 1 through an air duct pipe 5.

[0025] The air suction device 3 in the annular structure surrounds the top of the hearth 2 in all directions 360°, and the plurality of air suction grooves 31 increase the effective area of air suction, and under the action of the air extractor, ozone exhaust gas is discharged from the gap between the top of the hearth 2 and the wok 10 and is effectively absorbed by the air suction device 3, which helps to improve the collection and processing efficiency of the entire system for ozone and reduces the overflow of ozone into the indoor space.

[0026] This surrounding design makes the ozone discharged at any position on the top of the hearth 2 be covered by the air suction device 3, and there is no collection dead angle, so that the capture probability of ozone is greatly improved.

[0027] Since the air suction device 3 is annular, it forms a relatively uniform negative pressure environment around the top of the hearth 2, so that the heat is uniformly distributed and the bottom of the wok 10 is uniformly heated, which improves the cooking effect and makes the food heated more uniformly and reduces the phenomenon of local charring.

[0028] In the next embodiment, the top end of the air suction groove 31 is higher than the top end of the hearth 2, so that the air suction groove 31 can cover a wider area on the top of the hearth 2, including the space above the hearth 2 where ozone can spread, so as to more comprehensively collect ozone and reduce the possibility of ozone overflow.

[0029] In the next embodiment, the air duct pipe 5 passes through the back of the stove body 1, and is connected with the air suction device 3 and the air extractor;

[0030] In the next embodiment, the plasma burner 4 is arranged at the bottom of the hearth 2, and extends upward;

[0031] In the next embodiment, the plasma burner 4 comprises a flame jet pipe 41, a ceramic pipe 42 and an electrode needle 43, wherein in the electric flame cooking state, the electrode needle 43 is connected with high-voltage direct current above 1,000 volts, and the flame jet pipe 41 serves as a circuit return.

[0032] As shown in Figures 2-4 , the utility model places a medium-sized commercial frying pan 10 on the hearth 2, and when the electric flame cooking starts to work, the plasma burner 4 starts to work; during the combustion process, because the air extractor is connected with the air suction device 3 through the air duct pipe 5, when the air extractor starts to work, negative pressure will be formed in the annular air duct inside the air suction device 3; under the action of the negative pressure, the generated gas (including a large amount of ozone and other substances) will be sucked into the annular air duct through the air suction groove 31, and at the same time, the oil fume generated by the frying pan 10 during the explosive frying will also be sucked into the annular air duct; then, the sucked gas is extracted by the air extractor through the air duct pipe 5 and is discharged to the outdoor environment, so that most of the ozone and the oil fume can be effectively prevented from overflowing into the indoor environment.

[0033] As shown in Figure 5 , a large-sized commercial frying pan 10 is placed, and the frying pan 10 is in contact with the through hole 11 on the panel of the stove body 1 along the edge and is nearly sealed, when the electric flame cooking starts to work, the plasma burner 4 and the air extractor start to work, and negative pressure is formed in the annular air duct inside the air suction device 3; under the action of the negative pressure, the generated gas (including a large amount of ozone and other substances) will be sucked into the annular air duct through the air suction groove 31, and the frying pan 10 and the through hole 11 on the panel of the stove body 1 form nearly sealed along the edge, so as to prevent all the ozone from overflowing into the indoor environment.

[0034] It is obvious for those skilled in the art that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the utility model is defined by the appended claims instead of the above description, and therefore all the changes falling within the meaning and scope of the equivalent elements of the claims should be included in the utility model.
