Problems solved by technology

[0004] The problem with general purpose vacuums is that you may not be able to get a good DPU on one or both types of floors, and as a result the overall DPU rating and combined annual energy expenditure (AE) rating of the vacuum cleaner may not be good

Embodiment Construction

[0037] Reference attached figure 1 , shows an upright vacuum cleaner comprising a floor engaging head 10 supported by front 12 and rear 13 wheels. An upright body portion 11 is pivotally mounted to the rear of the head 10, the body portion 11 including a handle 14 for guiding the cleaner. The head 10 includes an elongated transverse suction port 15 positioned proximate to the front wheel 12 . A rotating agitating brush 16 extends across the suction opening 15 for beating and sweeping the floor surface during the cleaning process.

[0038] A motor and fan unit 17 provided in the head 10 may drive the stirring brush 16 through a belt (not shown). In an alternative embodiment, the stirring brush 16 may be driven by a separate motor (not shown). In another alternative embodiment, the motor and fan unit 17 may be provided within the upright body portion 11 .

[0039] The motor and fan unit 17 generates a reduced air pressure in the duct 18 , which communicates through the neck ...

Abstract

The vacuum cleaner includes a sensor 24 that senses movement of the head 10 of the cleaner. The sensor 24 is connected to a controller 25 which is arranged to reduce the power applied to the motors of the motor and fan unit 17 when the sensor 24 detects that the head 10 is accelerating or decelerating above a predetermined limit, so that the head 10 is When decelerating, changing direction and accelerating again during the cleaning stroke, the vacuum cleaner consumes less energy instantaneously. When the sensor 24 detects that the head 10 is stationary, the controller 25 reduces the power applied to the motor of the motor and fan unit 17 . The energy applied to the stirring motor can also be reduced. The reduction in motor energy provides improved energy consumption for the vacuum cleaner.

Description

technical field [0001] The present invention relates to a vacuum cleaner. Background technique [0002] Regulations in some countries require that information must be provided for most vacuum cleaners in order to let the customer know the Annual Energy Expenditure (AE) and the suction capacity or so-called DPU according to the expected use of the vacuum cleaner on hard floors and / or carpets. [0003] The standard test procedure for determining the energy efficiency rating of a general purpose vacuum cleaner includes evaluation of the DPU capabilities on both types of floor surfaces described above. The value on which the AE energy consumption rating is based is the product of 50% of the DPU value obtained by cleaning each floor type respectively, and the fan motor power required to obtain the DPU on each floor type above. [0004] The problem with general purpose vacuums is that you may not be able to get a good DPU on one or both types of floors, with the result that the o...
