での塵埃の吸込み性能が低下することがない。It is needless to say that such a basic use form is mainly suitable for cleaning the floor surface, but in this use form, the tip end portion of the suction hose 33 is fitted to the hose support 49 as described above. Since the hose support 49 communicates with the upstream side of the dust collecting bag 31 as a filter, the outside air is sucked through the suction hose 33 because the hose support 49 is held in a closed and closed state. Is prevented. Therefore, in the basic use mode, the first suction system, that is, the collection chamber 82 of the main body 52 of the suction port body 13 to the collection chamber 23 of the dust collection chamber 23 via the inner pipe portion 62 of the communication pipe 51.

果を期待できる。In this air circulation type cleaning, since most of the air discharged from the electric blower 35 is circulated between the cleaner body 12 and the suction port body 13 as described above, the electric blower 35 is generated. The heat generated increases the temperature of the circulating air. Therefore, since such high-temperature air passes into the dust collection chamber 23, the circulating air can kill harmful microorganisms in the dust collection chamber 23.
Moreover, since the circulating air of high temperature is blown onto the surface to be cleaned from above immediately after rotating the rotary cleaning body 53, it is possible to expect a killing effect on harmful microorganisms contained in the surface to be cleaned.

Suction hose 33 without closing the suction flow passage in 3
The outside air can be sucked in through. When the suction hose 33 is used, the auxiliary suction port body in which the opening of the grip tube 33a at the tip thereof is directly connected or is appropriately inserted and connected to the grip tube 33a by utilizing the flexibility and stretchability of the hose 33 itself. The tip end opening of 48 is made to face a relatively high cleaning place such as a table or a wall, or a desired cleaning place such as around a shovel of a shoji screen or a glass of a door, and dust can be sucked from the place. Therefore, the suction port body 1 is much larger in shape than the grip tube 33a and is mainly adapted for floor cleaning.
In the case of No. 3, it is possible to easily clean a place where cleaning is not appropriate by using the suction hose 33 if necessary. Therefore, the vacuum cleaner 11 having the above-described configuration is convenient because the suction port body 13 and the suction hose 33 can be selectively used according to the cleaning location.

Even when the suction hose 33 is used as described above, the suction hose 33 can be sucked. Without closing the first suction system via the mouthpiece 13, the first suction system can still maintain air circulation between the cleaner body 12 and the suction mouthpiece 13. Therefore, even in the use mode in which the suction hose 33 is used, the harmful microorganisms in the dust collection chamber 23 can be killed by the air circulated in the dust collection chamber 23 due to the temperature raised by the heat generated by the electric blower 35.

Since it is possible to limit the amount of circulating air to a small amount while maintaining the circulation of the air over 3, the influence of the intake negative pressure on the suction hose 33 used in this state increases and a large amount of air passing through the suction hose 33 is secured. , Suction hose 3
The dust suction power at 3 can be increased. Moreover, limiting the air passage cross-sectional area of the first suction system as described above when the cleaner body 12 is placed in a self-supporting position can reduce the circulating air volume, so that the rotation cleaning body 53 automatically rotates. Can be decelerated or stopped, and therefore the adverse effect on the same place on the floor surface due to the scraping action of the rotary cleaning body 53 can be reduced.
