no. 1 approach

[0024] figure 1 It is a perspective view which shows 1st Embodiment of the vacuum cleaner which concerns on one aspect of this invention.

[0025] like figure 1 As shown, the electric vacuum cleaner 1 is a stick-shaped cordless electric vacuum cleaner. The stick-shaped cordless electric vacuum cleaner includes a vacuum cleaner body 10, a battery 40 detachably mounted on the vacuum cleaner body 10, and one end 61a detachably connected to the vacuum cleaner body 10. The extension pipe 60 and the suction port body 70 detachably connected to the other end 61b of the extension pipe 60. In addition, in the vacuum cleaner 1, the suction port body 70 may be directly connected to the vacuum cleaner body 10 without interposing the extension pipe 60, and it may be used as a hand-held type.

[0026] In addition, in this embodiment, the stick-shaped vacuum cleaner is exemplified, but one aspect of the present invention may be a stick-shaped vacuum cleaner, a canister-type vacuum cleaner,...

[0100] (Third Embodiment and Modifications thereof)

[0101] Figure 11 (A) is a plan view of the discharge part of the third embodiment, Figure 11 (B) is a plan view of a modified example of the second embodiment. In addition, in Figure 11 In (A) and (B), for Figure 10 The same elements in (A) and (B) are denoted by the same reference numerals.

[0102] like Figure 11 As shown in (A), in the case of the third embodiment, the rolled portion 221fa and the pair of protruding portions 421fb of the discharge portion 421f are composed of a single conductive sheet, as in the second embodiment. In addition, each protruding portion 421fb is formed by a band having a plurality of sharp acute corner portions 421fba at the tip.

[0103] like Figure 11 As shown in (B), in the case of the modified example of the third embodiment, a strip having a plurality of sharp acute-angled portions 521fba at the tip is provided so as to protrude from the entire one long side of the rolled ...

Abstract

An electric dust collector is provided with a suction device, and the suction device comprises an electric component accommodating part which is provided with a housing for accommodating an electric blower and a control substrate; an operation unit that switches between driving and stopping of the electric blower; and a discharge unit. The operation part is provided with a switch part and a wiring part capable of electrically connecting the switch part and the control substrate. The discharge unit is provided in the wiring unit at a position in the vicinity of the switch unit, and discharges static electricity into the air within the housing.

Description

technical field [0001] The present invention relates to electric vacuum cleaners. Background technique [0002] In a conventional electric vacuum cleaner, since the dust on the surface to be cleaned is sucked together with the air, static electricity caused by friction is sometimes generated between the ventilation path in the electric vacuum cleaner and the dust or air, and the static electricity is transmitted from the electric vacuum cleaner to the user's hands, causing discomfort. [0003] In addition, Japanese Patent Application Laid-Open No. 10-55895 proposes a vacuum cleaner in which an electrostatic discharger capable of removing static electricity from a charging member from short fibers of a felt is provided on the outside of a suction channel. The end of the discharge into the air. SUMMARY OF THE INVENTION [0004] Dust (particularly dust) is sucked while being scraped by the suction port body having a rotating brush, thereby generating static electricity, whi...
