Abstract

A vacuum cleaner (1001) includes a cleaner body (10) capable of standing and inclining, an electric blower (1) accommodated in the cleaner body (10), a floor nozzle (16) capable of cleaning a surface while the cleaner body (10) inclines, a mode detector (3) detecting whether the cleaner body (10) stands or inclines, and a controller (2) controlling a power supplied to the electric blower (1). The controller (2) is operable to supply a first power the electric blower (1) if the mode detector (3) detects that the cleaner body (10) inclines, and to supply a second power lower than the first power to the electric blower (1) if the mode detector (3) detects that the cleaner body (10) stands. This vacuum cleaner (1001) prevents the electric blower (1) from overheating.

Description

technical field [0001] The invention relates to an electric vacuum cleaner. Background technique [0002] Figure 12 It is a rear perspective view of a conventional electric vacuum cleaner 501 described in Patent Document 1. FIG. In the vertical (vertical) electric vacuum cleaner 501, accessories such as the suction piece 51, the extension pipe 52, the small suction nozzle 53, the dust removal brush 54, etc. suitable for cleaning in various places are installed on the main body 50 of the vacuum cleaner for ease of use. The floor suction nozzle 56 is rotatably supported on the rear lower portion of the cleaner main body 50, and sucks dust from the cleaning surface. [0003] When cleaning the floor surface normally, hold the handle 57 located on the upper part of the cleaner main body 50, put the cleaner main body 50 down, and move the floor suction nozzle 56 on the floor surface. [0004] In the case where the user is using one of the above accessories, if Figure 12 As sho...
