Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rotary rotor built in a floor nozzle used as an attachment of a vacuum cleaner.
[0002]
[Prior art]
FIG. 6 shows a conventional rotating rotor. In the figure, 51 is a rotating rotor, and the rotor 52 constituting the rotating rotor is made of a metal columnar shape, and a cleaning body 54 is inserted and fixed in a plurality of support grooves 53 opened on the outer periphery thereof, and the rotor 52 is twisted around an axis. In addition, the cleaning body 54 is formed in a spiral shape, and a driven side bracket 57 integrally including a driven pulley 55 and a shaft 56 and a play side bracket 58 integrally including a shaft 56 are fixed to both ends of the rotor 52, respectively, and further outside thereof. A bearing holder 61 that press-fits the bearing 60 is attached via a washer 59, and is assembled in a state where it is rotatably supported.
[0003]
When the rotary rotor 51 of the conventional floor nozzle for a vacuum cleaner configured as described above is rotated, the cleaning body 54 rubs against the floor surface, scrapes up dust on the floor surface, and exhibits a cleaning effect.
[0004]
[Problems to be solved by the invention]
However, according to the rotary rotor 51 of the floor nozzle for a vacuum cleaner configured as described above, the rotary rotor 51 has the rotor 52 made of a metal column, and the cleaning body 54 is formed in the plurality of support grooves 53 that open to the outer periphery thereof. And the rotor 52 is twisted around the shaft to make the cleaning body 54 spiral. For this reason, the rotor 52 needs to be twisted after being processed into a metal columnar shape having a plurality of support grooves 53 opened on the outer periphery thereof. Therefore, the rotor 52 has a problem that machining is complicated and machining accuracy such as runout during rotation is not good.
[0005]
The present invention has been made to solve the above-described problems, and provides a rotating rotor that can simplify the processing of the rotating rotor and improve processing accuracy such as runout during rotation. It is aimed.
[0006]
[Means for Solving the Problems]
The rotary rotor of the floor nozzle for a vacuum cleaner according to the present invention is configured as follows.
(1) In a floor nozzle for a vacuum cleaner provided with a rotary rotor in the vicinity of the opening in a main body case having a horizontally long opening for sucking dust on the bottom surface, the rotary rotor includes a rotor and a cleaning body, and the rotor together has a plurality of grooves parallel to the axial direction which opens to the outer periphery, the cleaning body and a plurality of divided base is formed from the cleaning member in communication with divided base of said plurality of said plurality of each of the divided base, by attaching to the groove adjacent to each other of the rotor, in which the cleaning member is continuously formed at a position obtained by adding a predetermined angle twisting about the axis of the rotor is there.

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1
1 to 4 show the first embodiment. FIG. 1 is a perspective view of a rotary rotor of the present invention. In FIG. 1, 1 is a rotary rotor, 2 is a rotor, 3 is a cleaning body, 9 is a groove part. FIG. 2 is a perspective view of a state in which the cleaning body is mounted on the rotor. In FIG. 2, 4, 14 and 24 are base parts, and 5 is a cleaning piece. FIG. 3 is a front view of the cleaning body mounted on the rotor. FIG. 4 is a plan view of the cleaning body. In FIG. 4, 6 is a slit and 7 is a round hole. The rotary rotor of the present invention is composed of a rotor 2 and a cleaning body 3 as shown in FIG. The rotor 2 has a cylindrical shape, and a groove portion 9 that is parallel to the axial direction is opened on the outer peripheral portion at a position equally divided by four in the circumferential direction. As shown in FIG. 4, the cleaning body 3 is formed in a substantially rectangular shape, and has a cleaning piece 5 on one side and a plurality of base parts 4, 14, 24 on the other side. Between the base parts 4 and 14 and the base parts 14 and 24, a substantially T-shaped slit 6 having round holes 7 at both ends is formed, and the base parts are divided by the slit 6.
[0008]
Next, referring to FIG. 2 and FIG. 3, the mounting state of one cleaning body will be described. As shown in FIGS. 2 and 3, the cleaning body 3 has base portions 4, 14, and 24 attached to groove portions 9 adjacent to each other with respect to a groove portion 9 formed on the outer peripheral portion of the rotor 2. Since the cleaning body 3 has the base part divided by the slit 6 and has the cleaning piece 5 on one side, the outer peripheral part of the rotor 2 is at a position to which a predetermined angular twist is applied around the shaft. The cleaning piece 5 is continuously formed. Further, when the four cleaning bodies 3 are mounted on the groove portions 9 adjacent to each other with respect to the groove portions 9 formed at the positions equally divided in the circumferential direction, as shown in FIG. On the outer peripheral portion of the shaft 2, four cleaning bodies 3 each having a cleaning piece 5 formed continuously with respect to a position where a predetermined angle twist is applied around the shaft, and a rotary rotor 1 including the rotor 2 are formed. .
[0009]
Since the rotary rotor according to the first embodiment is configured as described above, it is not necessary to twist the rotor at a predetermined angle around the axis, so that the processing of the rotor can be simplified and made inexpensive. In addition, since the rotor is not twisted, the accuracy of the rotating rotor such as runout during rotation can be improved. Furthermore, since round holes are formed at both ends of the slit, there is no damage such as tearing of the cleaning body 3 during rotation.
[0010]
FIG. 5 shows another example of the first embodiment. FIG. 5 is a front view of the cleaning body showing another example of the first embodiment. In FIG. 5, 8 is a brush, 13 is a cleaning body, 16 is a slit, and 17 is a round hole. As shown in FIG. 5, the cleaning body 13 is formed in a substantially rectangular shape, and has a brush 8 on one side and a plurality of base parts 4, 14, 24 on the other side. Between the base parts 4 and 14 and the base parts 14 and 24, a substantially T-shaped slit 16 having round holes 17 at both ends is formed, and the base parts are divided by the slit 16.
[0011]
Since the cleaning body of another example of Embodiment 1 is configured as described above, the brush formed on one side of the cleaning body scoops up dust on the floor surface and exhibits a cleaning effect.
[0012]
Note that the rotary rotor of the present invention uses a generally T-shaped slit to divide the base of the cleaning body, but the slit shape, etc., is set to the optimum shape in a timely manner according to the purpose. However, there is no problem. Also, regarding the number of the base parts of the cleaning body and the position of the groove part where the base part is to be mounted, depending on the purpose, for example, the outer peripheral part of the rotor is formed into a V-shape at a position where a predetermined angular twist is applied around the shaft. There is no problem even if the mounting position is appropriately set so that the cleaning piece is formed.
[0013]
【The invention's effect】
As is clear from the above description, the floor nozzle for a vacuum cleaner of the present invention can obtain the following effects.
[0014]
Since the rotor does not need to be twisted at a predetermined angle around the shaft, machining of the rotor can be simplified and made inexpensive. In addition, since the rotor is not twisted, the accuracy of the rotating rotor such as runout during rotation can be improved. Furthermore, since round holes are formed at both ends of the slit, there is no damage such as tearing of the cleaning body 3 during rotation. Further, in the rotating rotor when a cleaning body having a brush on one side is used, the brush formed on one side of the cleaning body scoops up dust on the floor surface and exhibits a cleaning effect.
