Embodiment Construction

[0026] A vacuum cleaner according to a first aspect of the invention, generally indicated at 10, is shown at figure 1 middle.

[0027] The vacuum cleaner 10 includes a main body portion 12 , a separation device 14 , a flexible hose 16 , a wand assembly 18 and a cleaner head 20 . The main body portion 12 is shown independently in the figure 2 and 4 middle.

[0028] Mounted in the main body portion 12 is a motor driven fan unit 114 for generating an air flow through the separation device 14 in use, a cable rewind unit (not shown) for retracting the cable and storing it in the main body portion 12 , and appropriate control electronics 118 for controlling the cylinder vacuum cleaner 10.

[0029] The motor driven fan unit 114 and cable rewind unit are conventional and will not be described in detail herein.

[0030] The motor driven fan unit 114 is accommodated in the motor barrel 115 . The motor bucket 115 is connected to the main body 12 so that in use the motor driven fan...

Abstract

A vacuum cleaner 10 has a main body 12, a motor-driven fan unit 114, a printed circuit board 122 for controlling the motor-driven fan unit 114 and a housing 128 encasing a portion of the printed circuit board 122. A heat sink 130 of the printed circuit board 122 extends through the housing 128 from an interior of the housing 128 to an exterior of the housing 128. The printed circuit board 122 is disposed within the main body 12 such that the heat sink 130 is located in an air-flow path through the main body 12.

Description

technical field [0001] The present invention relates to a vacuum cleaner, and in particular to a vacuum cleaner having a printed circuit board. Background technique [0002] Printed circuit boards, commonly referred to as PCBs, are widely used for the electrical controls of vacuum cleaners. It is desirable for the PCB to be as small as possible, however reducing the size of the PCB may have associated disadvantages such as an increase in temperature during operation of the PCB. Contents of the invention [0003] According to an aspect of the present invention, there is provided a vacuum cleaner comprising: a main body; a motor-driven fan unit; a printed circuit board for controlling the motor-driven fan unit; and a case enclosing a part of the printed circuit board, in which A heat sink for the circuit board extends from the interior of the housing through the housing to the exterior of the housing, and the printed circuit board is arranged in the body portion such that t...
