2. Description of the Related Art Conventionally, a suction tool of this kind is, for example,
What was described in -50857 was common. This will be described below with reference to FIG. An agitator-2, a drive source 4 for driving the agitator-2 via a belt 3, and a control board 5 for controlling the drive source 4 are provided in the suction tool 1. Is provided with a positive temperature coefficient thermistor 6 which is a protection element for the driving source 4. In carpet cleaning, the agitator 2 is rotated to sweep out dust on the carpet, and the driving source 4 is clogged with dust. When an overload is applied to the element 4, the positive temperature coefficient thermistor 6 generates heat with an increase in the current value, so that the current circuit is interrupted. The positive temperature coefficient thermistor 6 cuts off the current circuit when the temperature rises.
It was necessary to always cool at.

However, in such a structure, the control board 5 is provided in parallel with the lower surface of the suction tool 1, so that the control board 5 occupies a large area with respect to the suction tool 1, and the suction tool 1 is electrically operated. In recent years, the size of the control board 5 has been increasing, and it has been difficult to reduce the size of the suction tool 1. Further, since the positive temperature coefficient thermistor 6 which is a protection element of the drive source 4 is also provided on the control board 5, it cannot be installed at a position near the suction port where the air volume is large, and the cooling thereof is sufficiently performed. When a carpet with a large load cannot be cleaned, the PTC thermistor 6 operates, and the rotation of the agitator 2 tends to stop. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to reduce the size of a suction tool and efficiently cool a heat-generating component.
