It is set to the cut-off position.

Reference numeral 38 denotes a filter case that is detachably attached to the front surface of the main body case 5. The filter case 38 has a substantially U-shaped cross section with its top and back surfaces open, and has a large number of exhaust holes 39 in its bottom surface.

When this filter case is slid upward from the bottom of the front surface of the main body case 5, it is engaged and held by a pair of protrusions 40, 40 formed on the front surface of the main body case 5, and in this held state, the front plate 1
A sealed hair collection chamber 41 is formed between the hair collection chamber 5 and the hair collection chamber 41 .

Numeral 42 is a pair of protrusions formed on the inner surface of the filter case 38 in two long vertical rows, 43 is a pair of protrusions also formed inside the filter case 38, and 44 is a protrusion that can be freely attached to and removed from the upper opening 45 of the filter case 38. This filter is inserted and installed, and includes a filter body 46 made of plastic net or the like in the shape of a flat rectangular tube, and a protective frame 47 for this filter body.
It consists of. Reference numeral 48 denotes a flange formed at the upper end of the protective frame 47, which has a ventilation hole 49 in the center and is sized to close the upper surface opening 45 when it is installed in the filter case 38. 50 is a guide rib formed on the protection frame 47 to be elongated in the vertical direction. When the filter 44 formed in this manner is inserted into the filter case 38, the front surface of the protective frame 47 and the back surface of the guide rib 50 are in sliding contact with the protrusions 42 and 43, respectively, so that the filter 44
is always set at a predetermined position, and the filter body 46
A predetermined ventilation space 51 is formed in the front, rear, left and right sides of the filter case 38 , and the stepped portion 11 of the front case 6 is pressed toward the main case 5 by the upper end of the filter case 38 .
