示すように送られる。Next, the operation will be explained. First, when the main body is operated to operate in the first mode, the electric suction device inside the main body 9 performs a suction operation as shown in FIG. The formula brush 4 rotates in the direction of arrow B. Then, the user moves the suction tool 1 forward on the carpet. Cotton dust, hair, etc. on the carpet are brushed up by the rotary brush 4. At this time, the lip member 20 functions to prevent the dust thrown away by the rotary brush 4 from coming out backward. Then, the dust that is directly thrown upward by the rotary brush 4 and the dust that hits the girder/tube member 20 is sent as shown by the arrow by the suction operation of the electric suction device.

第２のモードに切り替えて使用する。By the way, the rotary brush 4 that operates in the first mode is effective against relatively large debris such as cotton debris and hair, but is not effective against fine particulate debris that adheres to flat floors such as between boards. . Therefore, on a flat floor, the second mode is used.
本体側において第２のモードで動作するように操作する

込まれ、第５図の矢印Ｅが示すように送られる。In this case, power is transmitted to the wiping member 5, and the wiping member 5 rotates in the direction of arrow C. That is, the wiping member 5 rotates while in contact with a floor surface such as a board, and in this state, the user moves the suction tool 1 back and forth on the floor. Then, the dust on the floor is removed by the wiping member 5 into the rotating brush storage section 13.
being thrown towards. At this time, the wiping member 5 removes relatively fine particulate debris on the floor as well as relatively large debris.
The brush is scraped by -F and thrown forward, that is, toward the rotating brush housing section 13. The electric suction device is a first
The suction operation is performed in the same way as in the mode, and since the notch 19 and the notch 21 are formed in the dirt guide part 18 and the lip member 19, the dust from the wiping member storage part 16 passes through these notches. Rotating brush housing part 1
There is an airflow flowing towards 3. Therefore, the dust that has been repelled by the wiping member 5 is sucked through the suction port 12 at the lower part of the rotary brush accommodating part 13 through these notches, and is sent as indicated by the arrow E in FIG.
以上のように本実施例の電気掃除機では、吸い込み具に
回転式ブラシ４と拭き取り部５の双方を設けているので

する事が出来る。また、空気吸い込み口は回転式ブラシ
用収容部のみに設けられているので、比較的強い空気流
を得る事が出来、吸い込み機能が低下せず、綿ごみや毛
髪等の比較的大きなごみから粒子状のごみまで良好に吸
い取る事が可能になる。As described above, in the vacuum cleaner of this embodiment, the suction device is equipped with both the rotary brush 4 and the wiping part 5, so when cleaning carpets, etc., the rotary brush 4 is used, and when cleaning hard floors, the rotary brush 4 is used. In this case, by switching the operation mode such as activating the wiping member 5, it is possible to deal with both of the above cases without replacing the entire suction tool. In addition, since the air suction port is provided only in the rotary brush accommodating part, it is possible to obtain a relatively strong air flow, and the suction function does not deteriorate, and it is possible to remove particles from relatively large garbage such as cotton dust and hair. It is possible to effectively suck up even small particles of dirt.
尚、回転している拭き取り部材５には綿ごみおよび毛髪
等かい（らか付着するが、拭き取り部材収容部１６内に
は電動吸引装置による空気流は生じないので、拭き取り
部材収容部１６内にこれらのごみが集まる事は無く、拭
き取り部材５に綿ごみおよび毛髪等が巻き付く可能性は
非常に少ない。Incidentally, cotton dust, hair, etc. adhere to the rotating wiping member 5, but since no airflow is generated by the electric suction device in the wiping member accommodating portion 16, These dusts do not collect, and the possibility of cotton dust, hair, etc. getting wrapped around the wiping member 5 is very low.
