8 is a vertical sectional view and a bottom view showing an example of a floor suction tool of a conventional vacuum cleaner disclosed in Japanese Patent No. As shown in the figure, when the floor suction tool 50 is attached to the floor for cleaning, the switching lever 51 is operated to close the ventilation port 52, and the electric blower (not shown) is operated. Then, the outside air is sucked from the suction port 53, passes through the introduction hole 54 at a high speed, collides with the air turbine 55 and rotates it, and then passes through the connecting pipe 56 and is sucked into the vacuum cleaner main body. .

り込むことはない。When the air turbine 55 rotates, the rotating brush 57 connected thereto via a belt 56 also starts rotating, and sucks dust while scraping dust on the floor surface, particularly on a carpet, from the suction port 53. At this time, since the leak hole 58 is in contact with the floor surface and is closed, outside air does not enter through the leak hole 58.

Outside air is sucked into the turbine chamber 59 in a state of being dispersed from the introduction hole 54 and the leak hole 58. For this reason, the amount of outside air passing through the introduction hole 54 is reduced, and the rotation of the air turbine 55 is decelerated or stopped, and noise associated with the high-speed rotation of the air turbine 55 and vibration of the rotating brush 57 are reduced, and noise is reduced. Can be achieved.

ってしまう。According to the vacuum cleaner constructed as described above, when the floor suction device 50 is used, if the floor surface has irregularities or steps, the outside air is leaked from the leak holes 58. As a result, the rotation of the air turbine 55 is decelerated, and the dust scraping rate from the floor surface is reduced, or the rotation speed of the air turbine 55 is changed to generate an unpleasant rotation sound. On the other hand, if the leak hole 58 is reliably brought into contact with the floor surface, the floor surface may be damaged or may be caught on a step.

First, the switching device 18 is operated to slide the opening / closing plate 19 to reduce the area of the communication port 6a as shown in FIG. 2 and to operate the electric blower of the cleaner main body 1 for cleaning. Dust is sucked from the suction port 10 together with the outside air, enters the brush storage chamber 7, passes through the communication port 6 a, flows into the turbine storage chamber 9, and flows into the air turbine 16.
To rotate.

なお、回転ブラシ１１の回転は、床面４に凹凸がある絨
毯の場合に、より効果を発揮する。This rotation is transmitted to the rotating brush 11 via the belt 17 to rotate the cleaning element 12. Thus,
Dust on the floor 4, particularly dust that sticks or gets entangled with the floor 4, is separated from the floor 4 by the cleaning element 12, and is lifted up from the suction port 10 together with the outside air. And sucked in the direction of the cleaner body 1 while rotating the air turbine 16.
Note that the rotation of the rotating brush 11 is more effective in the case of a carpet having irregularities on the floor surface 4.

シール部材２８は床面４との接触を維持する。At this time, since the sealing piece 30 of the sealing member 28 attached to the outside air introducing portion 26 is made of a soft material, and reliably contacts the floor surface 4 to close the outside air introducing hole 27, the outside air introducing hole 27 is closed. Is not sucked into the turbine housing 9 from the outside air introduction part 26. Further, even if the floor surface 4 is formed of a hard material, the surface of the floor is not scratched or caught on a step, and even if the floor surface 4 has some irregularities, the sealing member 28 is not in contact with the floor surface 4. Maintain contact.

転ブラシ１１の振動が低減され、静音化が図れる。Next, when the floor suction device 5 is separated from the floor surface and cleaning is interrupted, the sealing piece 30 hangs down due to its elasticity to open the outside air introduction hole 27, and the outside air flows into the suction port 10 and the outside air introduction portion. 26 and is sucked into the turbine housing chamber 9 in a dispersed state. For this reason, the amount of outside air passing through the communication port 6a is reduced, and the rotation of the air turbine 16 is decelerated or stopped. Noise caused by the high-speed rotation of the air turbine 16 and vibration of the rotating brush 11 are reduced, and noise is reduced. Can be achieved.

As long as there is no outside air, the outside air is not sucked into the turbine housing chamber 9 from the outside air introduction part 26. Further, even if the floor surface 4 has some irregularities, the seal member 28 reliably maintains the contact with the floor surface 4. In particular, when the hanging length of the sealing piece 30 of the sealing member 28 is set to be slightly lower than the line connecting the lower ends of the front and rear wheels 23 and 24, the sealing piece 30 is more securely attached to the floor surface 4. Contact and the sealing effect is improved. Furthermore, even if the floor surface 4 is formed of a hard material, the seal member 28 is formed of a soft material, so that the floor surface is not scratched or caught on a step.

ので、シール部材が床面に傷等を付けることがない。As is apparent from the above description, the vacuum cleaner according to the present invention has the following effects. In the description, the same reference numerals as those in the claims denote the effects of the respective claims. (1) The outside air introduction portion is formed using a sealing member made of a soft material having elasticity, and the lower end portion is made substantially the same height as the lower end portion of the wheel. The outside air introduction section is closed by the seal piece to prevent the inflow of outside air, and does not slow down or stop the rotation of the air turbine. At this time, since the sealing member is made of a soft material, the sealing member does not damage the floor surface.

き、長寿命化に役立つ。When the floor suction tool is separated from the floor surface, the sealing piece opens the outside air introduction section, so that outside air flows in from the outside air introduction section positively, and the rotation of the air turbine is stopped or extremely stopped. Therefore, the rotation holding member such as a bearing accompanying the rotation of the air turbine can be prevented from burning, which contributes to a longer life.

れる。(6) Since the cylindrical, substantially rectangular parallelepiped or substantially elliptical cylindrical seal piece is divided into a plurality of seal pieces by slits, when the seal piece of the seal member moves on the floor surface, it moves forward and backward. The seal piece can be freely bent and easily deformed. For this reason, contact resistance accompanying the shape of the sealing member and the like can be reduced, and the operability of the floor suction tool can be improved as well as ensuring the sealing performance with the floor surface.

It is constituted by a seal piece so that the lower end of the seal piece hangs downward from the lower end of the wheel, and when the floor suction tool is advanced, the seal body is deformed downstream and closes the lower end of the outside air introduction section. With this configuration, the inflow of outside air from the outside air introduction portion is prevented, and the seal piece can reliably close the outside air introduction portion and prevent the floor surface from being damaged.
