Abstract

Abstract An electric cleaner for use in household and industry use provided with a control means (3) which is adapted to normally effect a constant rotation of the blow motor (2) in spite of the control of the rotation number of the operation unit in hand when the dust has not been detected by the dust sensor (7), and to effect the transfer control so as to increase the number of the revolutions of the blow motor up to the revolution number established by the operation unit in hand when the dust has been detected, whereby the electric cleaner is capable of effecting a cleaning operation quietly with the operational property being improved.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 123 words
An electric cleaner comprising a main body includ­ing a blow motor, whose revolution number is continuously varied by an operation unit in hand, and a dust collecting unit provided in the suction opening or between the suction opening and the main body, and a control means which is adapted to normally effect a constant rotation of the blow motor in spite of the control of the rotation number of the operation unit in hand when the dust has not been detected by the dust sensor unit, and to effect the transfer control so as to increase the number of the revolutions of the blow motor up to the revolution number established by the opera­tion unit in hand when the dust has been detected.
Claim 2
Dependent Claim 123 words
An electric cleaner comprising a main body includ­ing a blow motor, whose revolution number is continuously varied by an operation unit in hand, and a dust collecting unit provided in the suction opening or between the suction opening and the main body, and a control means which is adapted to normally effect a constant rotation of the blow motor in spite of the control of the rotation number of the operation unit in hand when the dust has not been detected by the dust sensor unit, and to effect the transfer control so as to increase the number of the revolutions of the blow motor up to the revolution number established by the opera­tion unit in hand when the dust has been detected.
Claim 3
Dependent Claim 122 words
An electric cleaner comprising a main body includ­ing a blow motor, whose revolution number is continuously varied by an operation unit in hand, and a dust collecting unit provided in the suction opening or between the suction opening and the main body, and a control means which is adapted to reduce the number of the revolutions of the blow motor by a constant percentage as compared with the number of the revolutions established by the operation unit in hand when the dust has not been detected by the dust sensor unit, and to control in transfer so as to rotate the blow motor with the number of the revolutions established by the operation unit in hand when the dust has been detected.
Claim 4
Dependent Claim 122 words
An electric cleaner comprising a main body includ­ing a blow motor, whose revolution number is continuously varied by an operation unit in hand, and a dust collecting unit provided in the suction opening or between the suction opening and the main body, and a control means which is adapted to reduce the number of the revolutions of the blow motor by a constant percentage as compared with the number of the revolutions established by the operation unit in hand when the dust has not been detected by the dust sensor unit, and to control in transfer so as to rotate the blow motor with the number of the revolutions established by the operation unit in hand when the dust has been detected.
