Definitions

  • the present invention relates to a high-frequency heating device, and more particularly, to a high-frequency heating device that suppresses heating unevenness of an object to be heated.
  • the slot antenna 31 and the slot antenna 32 include strip-shaped or arc-shaped slit holes 31b and slit holes 32b (openings) formed in the conductor portions 31a and 32a, respectively.
  • the slot antennas 31 and 32 use the slit holes 31b and 32b as high-frequency radiation portions. In particular, when the length of the slit holes 31b and 32b is approximately 1 ⁇ 2 of the wavelength used, the slit holes 31b and 32b can resonate and emit a strong high frequency.
  • Each of the slot antennas 31 and 32 has a substantially sector shape, and conductive paths 42 and 43 are connected to sides 31c and 32c corresponding to the radius of the sector shape.
  • the two slot antennas 31 and 32 are symmetrically arranged with the shaft connecting portion 21 that is the central portion of the antenna 20 as the center.
  • FIG. 7 shows the current flowing on the antenna flat plate 41.
  • the solid line represents the current flowing on the antenna flat plate 41, and the broken line represents the current flowing into and out of each conductive path.
  • the length of the broken line indicates the magnitude of the current.
  • the circularly polarized wave 101 emitted from the antenna flat plate 41 can emit a high frequency having a medium energy although it is slightly weaker than the energy emitted from the slot antenna 31. .
  • the high frequency tends to be relatively strong particularly at the end portion of the antenna flat plate 41 where current easily flows.
  • the outer peripheral end of the disk portion of the antenna flat plate 41 is referred to as a medium electric field region G having a moderate electric field strength (see FIG. 5).
  • measures such as changing the position and length of the conductive path 42 and the conductive path 43 are taken by analyzing and confirming with, for example, electromagnetic field simulation software. It is possible.
  • the slot antennas 31 and 32 having the first radiating portion 30 as the slit holes 31b and 32b formed in the conductor portions 31a and 32a connected to the antenna shaft 22, and the slot antenna.
  • Conductive paths 42 and 43 branched into two from 31 and 32, and a second antenna having an antenna flat plate 41 connected to the conductive paths 42 and 43 as a second radiation portion.
  • the two slot antennas 31 and 32 are provided, the center of gravity at the time of rotation is stable, the plane portion of the antenna 20 is less likely to be shaken at the time of rotation, and the operation is stabilized. Further, the slot antennas 31 and 32 are installed at positions that are symmetrical with respect to the shaft connecting portion 21 that is the center of the antenna 20. By doing so, the distance between the slot antenna 31 and the slot antenna 32 can be increased. Therefore, the interaction of the high frequency radiated from each of the slot antennas 31 and 32 can be suppressed, and the high frequency can be efficiently radiated from each of the slot antennas 31 and 32. As described above, the two slot antennas 31 and 32 enable stable center of gravity and efficient high-frequency emission.

Abstract

La présente invention vise à proposer un dispositif de chauffage à haute fréquence qui est apte à propager plus régulièrement dans une enceinte de chauffage des ondes à haute fréquence qui ont été produites par un oscillateur à haute fréquence. Une antenne (20) du dispositif de chauffage à haute fréquence comprend : des antennes à fentes (31, 32) qui utilisent, comme premières sections rayonnantes (30), des ouvertures en forme de fente (31b, 32b) qui sont créées dans des sections de conducteur (31a, 32a) connectées à une tige d'antenne (22) ; des trajets de conduction (42, 43) qui bifurquent par rapport aux premières sections rayonnantes (30) ; et une seconde antenne qui utilise, comme seconde section rayonnante (40), une plaque d'antenne (41) qui est connectée aux trajets de conduction (42, 43).
