According to the vacuum cleaner 1 of Embodiment 1 configured as described above, as shown in FIGS. 1, 3 and 4, the suction port body 6 has a relatively wide and dark floor surface (for example, a table or a bed). When cleaning the lower part, the electric blower of the cleaner body 2 and the illumination part 5b ₂₂ of the intake pipe 5 are turned on by the operation part 3b. Thereby, the light L is irradiated from the light source part 5b ₂₂₂ toward the transparent window part 5b ₂₂₁ . Then, the light L passes through the transparent window portion 5b ₂₂₁ and the first transparent window portion 6b ₂₁ of the light guiding portion 6b ₂ and enters the central mirror portion 6b ₂₃ .

At this time, mainly the light L of the right LED light is incident on the right side of the central mirror portion 6b ₂₃ , and the light L of the left LED light is incident on the left side of the central mirror portion 6b _23. Reflects left and right at an angle of °. Then, each light L reflected in the left-right direction from the central mirror portion 6b ₂₃ is reflected forward by the left and right end mirror portions 6b ₂₄ at an angle of about 90 °, and is transmitted through the second transparent window portion 6b _22. Radiated forward to the outside. Thereby, the visibility of the dust on the dark floor surface is improved, and the dust can be removed without leaving it.

At this time, air containing dust flows into the suction port body 6 from the suction port 6b ₄ , and the rotating brush 6b ₃ rotates by this air flow, and the dust on the floor surface is scraped into the suction port body 6. Dust-containing air is fed into the intake pipe 5 from the intake port 6b ₄ of the intake port body 6 through the connection port 6a ₂ and the intake port 5b ₂₁ of the intake pipe 5, and passes through the extension pipe 4 and the flexible hose 3. The dust passes through the dust cup unit 2b of the cleaner body 2 and is collected, and the air separated from the dust is exhausted to the outside through an exhaust port (not shown).

During this time, dust does not enter the sealed space R ₂ of the suction inlet body 6 and the sealed space R ₁ of the intake pipe 5. Therefore, dust adheres to each LED light, each transparent window part, each mirror part, or the like, or the light paths inside the illumination part 5b ₂₂ and the light guiding part 6b ₂ are blocked by the dust, thereby a pair of left and right second transparent There is no problem that the amount of light emitted from the window 6b ₂₂ to the outside is reduced.

Moreover, according to the vacuum cleaner 1 of Embodiment 1, when cleaning the floor surface of a narrow and dark space, such as between a wall and furniture or a refrigerator, as shown in FIG. The suction inlet main body 6 is removed, and the electric blower and the illumination unit 5b ₂₂ are turned on by the operation unit 3b. When the small nozzle portion 5b of the intake pipe 5 is inserted into a narrow and dark gap as a gap nozzle, the visibility of the dust on the dark floor surface is improved, so that it can be removed without leaving any dust.

As described above, according to the present invention, since the illumination unit 5b ₂₂ can cover both the illumination of the gap nozzle and the illumination of the suction port body 6, the vacuum cleaner can be manufactured at a low cost. One suction port F ₁ can be provided.
Note that a case has been exemplified for connecting push the small nozzle portion 5b of the fitting recess 6a ₁ to the intake pipe 5 of the connecting portion 6a of the suction inlet main body 6 in the embodiment 1, a connecting portion 6a and the small nozzle portion 5b You may provide the lock part locked so that engagement / disengagement is possible.
