Problems solved by technology

However, since the conductive wire is built inside the hose 55, and resistors with different resistance values ​​must be built in each fitting, the internal structure of the hose 55 and the fittings 51 to 54 becomes complicated.

Embodiment approach 1

[0055] When performing normal floor cleaning, hold the handle 17 located on the upper part of the cleaner main body 10, put the cleaner main body 10 down, and move the floor suction nozzle 16 on the floor.

[0056] When using the attachment 153 which is a small suction nozzle, for example, the user puts the cleaner body 10 upright, attaches the attachment 153 to the front end 11A of the hose 11, and operates the cleaner body 10 .

[0057] Figure 2A and Figure 2B It is a sectional view of the main part of electric vacuum cleaner 1001. The state detection unit 3 is constituted by a micro switch 3A operated by a lever 3B. The lever 3B is operated by a protrusion 5 integrally formed with the cleaner main body 10 . like Figure 2A As shown, when the vacuum cleaner main body 10 is in an upright state, the protrusion 5 does not operate the lever 3B, and the microswitch 3A does not operate, and is in an off state. like Figure 2B As shown, in a normal cleaning state in which t...

Embodiment approach 2

[0067] Figure 6E It is a partial enlarged view of the vacuum cleaner 1002 showing the suction force setting unit 12 . When the vacuum cleaner main body 10 is upright and the hose 11 is detached from the floor suction nozzle 16, the user can change the power supplied from the control unit 2 to the electric blower 1 by operating the suction force setting unit 12, thereby setting suction power. Thus, when cleaning with the front end 11A of the hose 11 detached from the floor suction nozzle 16, or when cleaning with an attachment attached to the front end 11A of the hose 11, the user can set the surface according to the surface to be cleaned. Suction power, get an easy-to-use electric vacuum cleaner 1002.

[0068] The accessory detection unit 13 discriminates the type of the accessory attached to the distal end 11A of the hose 11 . In Embodiment 2, in order to detect whether the attachment 14 which is an extension pipe is attached to the hose 11, the attachment detection part ...

Embodiment approach 3

[0079] In Embodiment 3, by detecting whether each accessory such as the extension pipe 14 or the crevice nozzle 155 attached to the front end 11A of the hose 11 is attached to the cleaner body 10, it is judged that it is not fixed to the cleaner body 10 but is detached. The type of the lower fitting, that is, the fitting attached to the front end 11A of the hose 11 . In this manner, the accessory detection units 13 and 24 constitute an accessory identification unit 113 for identifying an accessory that is not attached to the cleaner main body 10 , that is, removed from the cleaner 10 among the plurality of accessories 14 and 155 .

[0080] Figure 9C It is a partial enlarged view of the vacuum cleaner 1003 showing the suction force setting unit 112 . Only when at least one of the accessories 14, 155 is detached from the main body 10 of the vacuum cleaner, the user can use the suction force setting part 112 to set the power supplied to the electric blower 1. When the accessori...

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). Thecontroller (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...
