Claim 0:
1. A blower, comprising:
a brushless motor;
a fan configured to blow air by rotating around a rotational axis when the brushless motor is driven;
a housing (i) that houses the brushless motor and the fan and (ii) having an inlet opening that is configured such that the air is sucked into the housing through the inlet opening when the fan is rotated and a discharge opening that is configured such that the air blown by the fan is discharged from the housing through the discharge opening;
a handle protruding from the housing in a first direction orthogonal to the rotational axis of the fan;
a battery mounting part configured to detachably receive and retain a battery for supplying power to the brushless motor; and
a control device configured to control driving of the brushless motor,
wherein:
the brushless motor and the controller are configured such that a rotational speed of the brushless motor is in a range of 50,000 rpm to 120,000 rpm,
the fan has a diameter in a range of 30 mm to 50 mm,
the fan and the housing are configured such that a blowing force of the air discharged through the discharge opening is in a range of 1 N to 3 N,
the handle includes (i) a tubular grip part that (a) is configured to be held by a user, (b) extends in the first direction and (c) has a first end connected to the housing and an opposite second end in the first direction and (ii) a housing part that (a) is connected to the second end of the grip part and (b) has a larger dimension orthogonal to the first direction than the grip part, and
the control device is in the housing part.
