Abstract
A dielectric heating apparatus includes: a conveyance unit configured to convey an object to be heated; an electrode unit including a first electrode and a second electrode which face the object to be heated, that is conveyed in a first direction, in a second direction intersecting the first direction and which are applied with an alternating current voltage; and a metal first cover unit configured to surround the electrode unit. The first cover unit includes a first insertion port through which the object to be heated is inserted into the first cover unit, a first feed-out port through which the object to be heated is fed out of the first cover unit, and a plurality of first opening portions that are different from the first insertion port and the first feed-out port.
Claims19
A dielectric heating apparatus, comprising:
- a conveyance unit configured to convey an object to be heated;
- an electrode unit including a first electrode and a second electrode which face the object to be heated, that is conveyed in a first direction, in a second direction intersecting the first direction and which are applied with an alternating current voltage;
- and
- a metal first cover unit surrounding the electrode unit, wherein
- the metal first cover unit includes
- a first insertion port for inserting the object to be heated into the metal first cover unit,
- a first feed-out port for feeding the object to be heated out of the metal first cover unit, and
- a plurality of first opening portions that are different from the first insertion port and the first feed-out port, and
- the dielectric heating apparatus further includes an edge portion made of an electrically insulating magnetic material and continuously surrounding at least one of the first insertion port and the first feed-out port.
A dielectric heating apparatus, comprising:
- a conveyance unit configured to convey an object to be heated;
- an electrode unit including a first electrode and a second electrode which face the object to be heated, that is conveyed in a first direction, in a second direction intersecting the first direction and which are applied with an alternating current voltage;
- and
- a metal first cover unit surrounding the electrode unit, the metal first cover unit being in a rectangular parallelepiped having a top surface, a bottom surface, and first, second, third, and fourth sidewalls, wherein
- the metal first cover unit includes:
- a first insertion port for inserting the object to be heated into the metal first cover unit, and the first insertion port is formed in the first sidewall;
- a first feed-out port for feeding the object to be heated out of the metal first cover unit, and the first feed-out port is formed in the second sidewall facing the first sidewall;
- and
- a plurality of first opening portions that are different from the first insertion port and the first feed-out port, and the plurality of first opening portions are formed in only the third sidewall.
