Problems solved by technology

[0013] However, the rotary brush of the above-mentioned prior art is due to the structure in which the above-mentioned dust is removed by the line contact of each bristle with the dust on the floor surface along the rotation direction of the rotary brush. Therefore, as shown in FIG. When the grease 121 is contained, even if the rotary brush rotates, each bristle 122 cannot scrape the grease 121, and the grease 121 is only stretched thinly.
That is, the grease 121 on the floor surface cannot be reliably wiped off with the conventional rotary brush.
[0014] In addition, because the suction assembly of the conventional electric vacuum cleaner is a structure that only relies on the rotation of the rotary brush to remove the dust on the floor surface, especially for the dust near the floor that is easy to move with the movement of the suction assembly, it cannot be grasped. effectively remove

Embodiment 1

[0070] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 10 .

[0071] FIG. 2 shows a schematic structure of the electric vacuum cleaner of this embodiment. The above-mentioned electric vacuum cleaner is composed of a vacuum cleaner body 1 , an extension pipe 2 and a suction port assembly 3 .

[0072] The vacuum cleaner body 1 has an electric blower and a dust collector which are not shown. The electric blower sucks air through the suction port 5 (see FIG. 5 ) of the suction port assembly 3 . The dust collecting device is composed of, for example, a paper bag or a filter to remove dust, sand and other garbage contained in the sucked air.

[0073] The extension pipe 2 is a communication passage for introducing the air sucked by the suction port assembly 3 into the main body 1 of the vacuum cleaner.

[0074] As shown in FIG. 3 , the nozzle assembly 3 has a housing 4 , a nozzle 5 and a bristle array 6 .

[0075] The casing 4 is...

Embodiment 2

[0128] Hereinafter, other embodiments of the present invention will be described based on FIGS. 11 to 15( a ) and ( b ). The same structures as those in Embodiment 1 are designated by the same symbols, and their descriptions are omitted here.

[0129] This embodiment is the same as the first embodiment except that the second brush portion 31 (see FIGS. 1 and 6 ) of the first embodiment is replaced by the second brush portion 51 shown in FIG. 11 . As shown in FIG. 11, the 2nd brush part 51 is comprised from the loop brush 32 used in Example 1, and the blade 52 (elastic body).

[0130] The scraper 52 is a member that supports the loop brush 32. The first support portion 52a of the loop brush 32 is pasted, and while being connected to the first support portion 52a, it has a cross-sectional shape that can be inserted into the support portion 41b of the rotary body 13. Formed second support portion 52b constitutes. By inserting the second support portion 52 b of the blade 52 into...

Embodiment 3

[0154] Hereinafter, still another embodiment of the present invention will be described with reference to FIGS. 16 to 19 . The same structures as those in Embodiments 1 and 2 are given the same symbols, and their descriptions are omitted here.

[0155] This embodiment is the same as the first embodiment except that the second brush portion 31 (see FIG. 1 and FIG. 6 ) of the first embodiment is replaced with the second brush portion 61 shown in FIG. 16 . As shown in FIG. 16, the second brush part 61 is composed of the loop brush 32 used in Embodiments 1 and 2 and the blade 52 (elastic body) used in Embodiment 2, but in this embodiment, the loop brush 32 is different from embodiment 2 in the mode that sticks on the scraper 52.

[0156] That is, in the present embodiment, as shown in FIG. 16 , the loop brush 32 is only attached to the base cloth 32 b of the loop brush 32 and the brush hairs 32 a on the surface on the downstream side of the rotating body 13 on the scraper blade 5...

Abstract

This vacuum cleaner is equipped with a brush part on a rotary body of a rotary brush housed in a suction port unit. The brush part has a first brush part and a second brush part supported by support parts for the rotary boy. The first brush part is composed of straight brushes and the second brush part is composed of a loop brush and blades holding the loop brush. The support part is formed along a line linking points on the circumference of both end faces holding peripheral face of the rotary body. In the loop brush, each brush thread is formed into a loop shape by fixing both ends of each brush thread to a base cloth so that a line linking both ends of each brush thread is directed along the forming direction of the support part.

Description

[0001] This application is based on Japanese Patent Application (Application No.) No. 2002-381953 and Japanese Patent Application No. 2002-381986 filed in Japan on December 27, 2002, the contents of which are hereby incorporated by reference. technical field [0002] The invention relates to a suction port assembly of an electric vacuum cleaner with a rotary brush and the electric vacuum cleaner with the assembly. Background technique [0003] As a conventional electric vacuum cleaner or a suction nozzle unit used in the vacuum cleaner, there are, for example, techniques disclosed in Japanese Patent (Patent) Documents 1 to 3. These techniques will be briefly described below. [0004] Patent document 1 is the Japanese published patent publication "Japanese Unexamined Publication No. 2002-517 (disclosure date is January 8, 2002)", and patent document 2 is Japanese published patent publication "Japanese Unexamined Publication No. 6-14853 (disclosure date is 1994 January 25, 19...
