Further, when the sealing member 6 is made of a highly flexible material such as a rubber material, it may be formed in advance into a shape having the first sealing part 61 and the second sealing part 62.

Next, the operation of the air cleaner A1 will be explained.

According to this embodiment, as shown in FIGS. 3 to 7, a sealing member 6 is sandwiched between the housing portion 5 and the back panel 14. This increases the airtightness between this negative pressure part and the housing part 5 even if a negative pressure part is generated in the housing 1 due to the drive of the blower part 2 during operation of the air purifier A1. Is possible. Thereby, it is possible to suppress the air whose cleanliness should be detected by the detection unit 4 from being unintentionally sucked into the negative pressure space. Therefore, even if the operating state of the blower section 2 changes, the cleanliness can be detected more stably.

When the sealing member 6 is made of a rubber material, it is possible to bring the sealing member 6 into closer contact with the housing portion 5 and the back panel 14, as shown in FIGS. 6 and 7. This is preferable in order to improve the airtightness between the negative pressure part and the housing part 5.

The first sealing part 61 is sandwiched between the front surface 51 of the housing part 5 and the back panel 14. Thereby, the inside and outside of the opening 60 can be more reliably divided. Further, the second sealing portion 62 faces the side surface 52 from the outside in the x direction or the z direction. Thereby, even in a state where a gap may occur between the accommodating part 5 and the back panel 14 and the first sealing part 61, this gap can be closed by the second sealing part 62.

In this embodiment, the first sealing portion 61 is sandwiched between the surface 51 of the housing portion 5 and the recess 140 of the back panel 14 . The recessed portion 140 is a portion of the back panel 14 that is recessed toward the y1 side (front side) in the y direction. Therefore, when attaching the back panel 14 to the main body panel 11 from the y2 side (back side) to the y1 side (front side) in the y direction, the sealing member 6 can be pressed more strongly by the recess 140. is possible. This is advantageous in improving the airtightness of the sealing member 6.
