The burner 2 in the floating state can be in contact with the bracket body 32 which is dropped on the panel 1; under the condition of contact, if the outer side of the combustor is in contact with the support ring on the support body 32 in a suspension state, the support ring can discharge the ignition needle 4 to the combustor, and the electricity is conducted to the panel 1 (namely, the grounding), so that a discharge loop is formed, and discharge ignition is realized; meanwhile, under the condition of contact, the bracket body 32 can also play a certain limiting role in the suspended combustor 2, and the suspension stability is improved. When the burner 2 is separated from the holder body 32, discharge ignition can be achieved by high and low potentials. The burner 2 in this embodiment is suspended as follows:

the burner 2 is provided with a magnetic member (not shown in the figure), the panel 1 is correspondingly provided with an electromagnet 12, and the electromagnet 12 can generate magnetism repulsive to the magnetic member when being electrified, so that the burner 2 is suspended on the panel 1. By controlling parameters such as the current flowing through the electromagnet 12, the automatic lifting of the burner 2 can be realized.

The method specifically comprises the following steps: the electromagnet 12 is arranged below the panel 1 by taking the nozzle as the center; the magnetic member is a high temperature resistant permanent magnet, which is disposed at the lower portion of the burner 2 with the nozzle 11 as the center. And the lower part of the burner 2 is provided with a heat insulating layer for surrounding the magnetic member. Therefore, the influence of high temperature on the magnetic part can be avoided. Meanwhile, the electromagnet 12 is arranged below the panel 1, so that the panel 1 is simpler and is convenient to clean.

The nozzle 11 is connected with an air pipe for conveying fuel gas, and comprises the air pipe, the panel 1 and the like which are made of non-magnetic materials, so that the interference to a magnetic field is avoided. The fire power of the burner 2 is determined by the gas ejection amount of the nozzle 11, and can be controlled by a motor or a proportional valve, and the operation interface is controlled by a magnetic control knob or a projection.

Adopt suspension design's combustor 2 convenient when realizing the high regulation about the combustor, combustor 2 can be directly tak away from panel 1 when out of work, and at this moment, only remain nozzle 11 and pot support 3 on the panel 1, and pot support 3 can upwards rotate and keep away from panel 1, and then panel 1 of being convenient for is clean. Please refer to fig. 2.
