た。In the above-described conventional vacuum cleaner, the efficiency of the fan motor is not so high. In the case of a vacuum cleaner having a high input, the heat generated by the fan motor is large, and particularly, the exhaust gas is sucked. For exhaust-circulation type vacuum cleaners that do not circulate exhaust air to the outside air, the exhaust gas heats up, and when this high-temperature exhaust gas is sucked in again, the heat generated by the fan motor further increases, resulting in fan motor failure or fan motor malfunction. There has been such a problem that a protection device for preventing a failure has been activated and the device has stopped, and thus has not been put to practical use.
