Referring to FIG. 8, when there is no first suction means 17, as shown by a two-dot chain line, the first panel main body 35 is bent, so that the periphery 6 of the attached surface 5 and the edge winding 40 are There is a risk that oil or the like may enter in the direction of the solid arrow through the gap. However, the use of the first suction means 17 eliminates the bending of the first panel body 35 and makes it difficult for oil and the like to enter.

  Referring to (3) of FIG. 6, as shown in FIG. 16, the second metal foil molded body 61 of the second metal foil molded body 61 is matched with the width of the attached surface 5 as indicated by the direction of the dashed arrow. 2 The panel main body 65 is expanded and contracted. Here, the 1st panel main body 65 of the 2nd metal foil molded object 61 is formed so that expansion-contraction in a longitudinal direction is carried out, and the to-be-attached surface of the range hood 1 is expanded and contracted by the 2nd metal foil molded object 61 Can be adjusted to a size of 5. Therefore, the usability of the filter structure 11 is improved.

Therefore, the installation convenience on the back side of the attached surface 5 in the filter structure 11 is improved with respect to the attached surface 5 of the range hood 1.

  Referring to (2) of FIG. 7, an attracting force due to a magnetic force is generated in the edge winding 70 formed on the pair of short sides 72 a and 72 b of the second panel main body 65 of the second metal foil molded body 61. Each of the third suction means 19 and the fourth suction means 20 is attached.

That is, the first panel main body 35 of the first metal foil molded body 31 is contracted in the longitudinal direction more than the second panel main body 65 of the second metal foil molded body 61. Therefore, the first panel main body 35 of the first metal foil molded body 31 is also held by holding the edge winding 70 of the second metal foil molded body 61 by the fourth suction means 20. When the fourth suction means 20 is not provided, the first panel main body 35 and the second panel main body 65 are bent as shown by a two-dot chain line, so that the periphery 6 and the edge winding 40 and the edge of the attached surface 5 are bent. There is a possibility that oil or the like may enter the direction of the solid arrow through the gap between the winding 70. However, by using the fourth suction means 20, the bending of the first panel body 35 and the second panel 65 is eliminated, and oil or the like is less likely to enter. That is, the same effect as (1) of FIG. 9 is produced.

There is a risk that oil or the like may enter in the direction of the solid line arrow. However, by using the second adsorbing means 18 formed including the second holding body 27, the bending of the second panel main body 65 is eliminated, and oil or the like hardly enters. Moreover, since the bending of one long side 73a located on the near side of the mounting surface 5 of the second panel main body 65 of the second metal foil molded body 61 is eliminated by the second suction means 18, the range hood 1 The reliability of the mounting state of the filter structure 12 on the inner side of the mounted surface 5 is further improved with respect to the current plate 9.
