  The secondary filter 80 is made of, for example, filter paper that assists the filter unit 45, which is a primary filter or a main filter, and removes foreign matters other than oily smoke and odors, and uses a room temperature active catalyst such as activated carbon. Can do. Various types of secondary filters 80 can be used. The filter unit 45 may not be able to remove foreign matters.

  The rotary fan 85 is a well-known one, and rotates to generate a vacuum on the path, for example, in the exhaust gas supply pipe 37, the filter unit 45, and the discharge pipe 38, thereby improving the outflow of the exhaust gas. To do.

  Next, the operation of the filter unit 45 will be described. When the cooked food is set in the heating cooking chamber 22 and the cooking chamber door 24 is closed, and the filter unit 45 is set in the exhaust gas processing chamber 23 and the processing chamber door 26 is closed, the filter unit 45 is moved up and the filter unit 45 is moved. And the exhaust gas supply pipe 37 and the exhaust pipe 38 are completely watertightly engaged.

  Therefore, when a start switch (not shown) is turned on, the lower heater 33 and the upper heater 34 generate heat to heat the food. In this case, the motor 75 is turned on and rotated at the same time as the start switch is turned on or after a predetermined time has elapsed (for example, after generation of smoke from the food).

  When the motor 75 rotates, the rotor 55 in the filter unit 45 rotates indirectly. When the rotor 55 rotates, the water in the rotating body 56 is sprayed in the form of a mist from the plurality of elongated holes 56a toward the outside, and the inside of the rotating body 56 is brought into a negative pressure state. In this case, the suction action of the rotary fan 85 is also added and the inside of the rotary body 56 is in a high negative pressure state. The negative pressure is transmitted to the cooking chamber 22 via the compartment space 50 and the exhaust gas supply pipe 37.

  Then, exhausts such as odors and smoke generated in the cooking chamber 22 are introduced into the compartment space 50 in the filter unit 45 via the exhaust material supply pipe 37 and enter the rotor 55 from the compartment space 50. Then, it is sprayed into the water storage tank 46 in the form of mist from the plurality of elongated holes 56a while being dissolved in water.

  The water and exhaust discharged into the water storage tank 46 collide with the inner wall of the water storage tank 46 at a high speed to further increase the mixing of water and exhaust, and the odor and smoke in the exhaust are efficient for water. It is melted and removed.

  Thereafter, the exhausted matter from which odors and smoke are removed collides with the separation plate 65d to remove the contained water, and the exhausted matter from which the water has been removed removes foreign matters contained in the secondary filter 80. The exhausted material (most of which is air) from which foreign matter has been removed is discharged to the outside through the exhaust port 43.

  The present invention is not limited to the configuration of the above-described embodiment, and can be appropriately changed in design without departing from the gist of the invention.
