The connecting pipe 40 includes an exhaust port 44, a dust removing brush body 45, and a bumper 46.
It is detachably attached to.

The exhaust port 4 per unit time
If the amount of exhaust gas ejected from the air blower 4 is larger than the amount of intake air sucked into the electric blower 15, the exhaust gas is discharged from the periphery of the bottom surface of the floor suction tool 7 to the outside, so that dust on the floor surface 8 rises. Therefore, by reducing the ejection amount,
The outside air around the floor suction tool 7 is sucked from the seal piece 43, and the cleaning efficiency is improved. That is, the first exhaust holes 23
a and the opening area of the second exhaust hole 23 b
8b may be formed to be larger than the opening area, and exhaust holes 23a, 23 are provided to prevent exhaust of the circulating exhaust gas from the floor suction tool 7 and to allow dust to be absorbed around the floor suction tool 7.
It is desirable that the opening area of b and the air outside air intake 33 should be set such that exhaust hole ≧ air outside air intake.

The operation of the first embodiment configured as described above will be described. First, when the electric blower 15 is operated, the outside air near the bottom surface of the floor suction tool 7 is sucked into the suction port 42 together with dust on the floor surface 8, and passes through the handle portion 4 via the connection pipe 40 and the pipe 6. . At this time, the floating dust floating in the air from the floor surface 8 caused by the walking of the user or the movement of the floor suction tool 7 is combined with the outside air in the air outside air intake 3.
3 enters the first intake pipe 28a through the outside air communication port 34, merges with the outside air from the floor suction tool 7, passes through the dust collection chamber 9, becomes clean outside air, and cools the electric blower 15 by air cooling to a high temperature. High-speed exhaust is performed, and the exhaust gas enters the post-exhaust chamber 16. Exhaust chamber 1
The exhaust flow passing through the inside of the exhaust gas 6 at high speed causes the outside air in the exhaust air cooling body 20 located in the exhaust rear chamber 16 to flow into the exhaust rear chamber 16 along the exhaust flow due to a pressure difference from the atmosphere.

As a result, the temperature of the exhaust gas is reduced by the inflowing outside air, passes through the first exhaust air passage 25a, and enters the exhaust front chamber 21. The cooled exhaust gas is supplied to each of the exhaust circulation air passages 25b, 25c,
5d and 25f, and are ejected toward the floor 8 from the exhaust outlet 44. A part of the exhaust, that is, an exhaust larger than the amount of outside air entering from the air outside air intake 33 and the exhaust cooling body 20, The air is discharged from the first exhaust hole 23a and the second exhaust hole 23b into the air. Exhaust gas ejected toward the floor 8
The dust on the floor 8 is moved to the suction port 42 while rising, but since the temperature is low, the user does not feel uncomfortable, and the floor 8 is made of, for example, a synthetic material. However, there is no worry about thermal deformation. Further, since the air outside air intake 33 is provided behind the handle portion 4 (on the side of the cleaner body), it is difficult for the outside air to touch the human body, so that the user does not feel uncomfortable and it is difficult to hear the unpleasant suction sound. .

At this time, since the amount of exhaust air circulating is smaller than the amount of intake air, the outside air a outside the floor suction tool 7 bends the sealing piece 43 toward the suction passage 41, and the suction port 42 together with dust. The water is sucked and merges with the jet stream to repeat the circulation. Further, the floor suction tool 7 reliably sucks not only the dust between the seal pieces 43 formed facing each other but also the dust around the seal piece 43. Therefore, in order to surely suck the dust on the floor surface 8 and also simultaneously suck the dust floating in the air, the cleaning room including the space is cleaned. Further, when there is almost no dust floating in the air, the switching valve 35 is operated to close the outside air communication hole 34 so that the outside air is not taken in from the air and the amount of outside air sucked from the floor suction tool 7 is reduced. You can do much. In the first embodiment, the first exhaust holes 23a are provided in the circulation air passage.
And two second exhaust holes 23b are shown, but either one or two or more may be provided.

[Embodiment 2] FIG. 8 is a longitudinal sectional view of a handle portion showing Embodiment 2 of the present invention. As shown in the figure, the handle portion 4 includes a substantially hollow grip portion 47, a first intake pipe 28a, and a fourth circulating air passage 25d, and connects the first intake pipe 28a to the hose body 26. A connection cover 48 is provided on a partial outer periphery. The grip portion 47 has an air outside air intake 49 provided at an end thereof and a grip portion 47.
, An outside air communication port 50 communicating with the first intake pipe 28a, and an outside air communication port 50 and an air outside air intake 49.
, A dust collecting filter 52 provided near the air outside air intake 49 of the outside air introduction passage 51, and an outside air near the outside air communication hole 50 of the outside air introduction passage 51. A switching valve 53 for slidably opening and closing the communication port 50 from the outside is provided.

According to the second embodiment configured as described above, when the electric blower 15 is operated, the outside air passes through the outside air introduction passage 51 from the air outside air intake 49, and passes through the outside air communication port 50 to the first air. The air enters the suction pipe 28 a, merges with the outside air from the floor suction tool 7, and moves to the dust collection chamber 9.
At this time, the dust floating in the room also moves to the dust collection chamber 9 together with outside air from the air outside air intake 49. In addition, the user needs to move the handle portion 4 to clean the interior while moving inside the room.
Also move in the air. As a result, dust floating in the room can be absorbed over a wide area, and the floor 8 as well as the air can be cleaned, and the room can be cleaned. If the amount of floating dust is small, the switching valve 53 is operated to
By closing the outside air communication port 50, the amount of outside air sucked from the floor 8 can be increased.

In the above description, the cleaner body 1 and the connecting body 2
Although the case where exhaust holes 23a and 23b for discharging a part of the exhaust air from the electric blower are provided is shown in FIG. Further, in the above description, the case where the air outside air intake ports 33 and 49 are provided in the handle portion 4 of the connecting body 2 is shown, but it may be provided in a place other than the handle portion 4.
