DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. Reference numeral 21 denotes a floor nozzle body for a vacuum cleaner (hereinafter simply referred to as a main body), which has a bumper 22 around it and connects an upper body member 23 and a lower body member 24 as shown in FIG. It consists of. Inside the main body 21, there is provided a suction chamber 25 which is a dust suction port opened to the floor side. An opening 26 communicates with the center of the suction chamber 25. This opening 26 is
A communication pipe 27 is rotatably sandwiched between the upper body member 23 and the lower body member 24 behind the main body 21 and communicates with the inside of the connection pipe 28. The connection pipe 28 is a vacuum cleaner main body (not shown).
Is in communication with A motor 29 drives an agitator 31 provided in the suction chamber 25 via a belt 30. Further, both side portions of the opening portion 26 are formed as a sub opening portion 32 having a passage communicating with the sub suction chamber 33.

In the present embodiment, the sub suction chamber 33 is connected to the suction chamber 25.
Outside the front side and both sides, the suction chamber 25
Apart from this, it is provided independently on the lower body member 24. The sub suction chamber 33 has an area smaller than the area of the suction chamber 25. The opening 26 is provided with the sub-opening 3.
Switching means 36 is provided for switching between the passage 2 and the opening 26. In the present embodiment, the switching means 36 has a rotating shaft 36a substantially at the center of the opening 26 as shown in FIG.
It is composed of two partition plates that rotate left and right about this rotation axis. That is, in the state of normal use, the opening 26
The sub-openings 32 are both open. When the corner cleaning mode is set, the operation is performed so as to turn left and right around the rotation shaft 36a to close the opening 26 and open only the sub-opening 32.

The operation of the embodiment will be described below. In this embodiment, when cleaning the center of the room, the suction chamber 25 is used.
The sub suction chamber 33 is used when cleaning a corner of a room such as a wall, for example. Since the sub suction chamber 33 has an area smaller than the area of the suction chamber 25, when the switching means 36 is driven to close the opening 26 and use only the sub opening 32, a very large suction force is applied to the sub suction chamber. 33. That is, since the suction force at the edge of the wall is very large, there is no need to remove the main body 21 and replace it with a gap nozzle as in the conventional case.

As described above, in the present embodiment, the opening 26 communicating with the suction chamber 25 and the sub opening 3 communicating with the sub suction chamber 33 are provided.
And a switching means 36, which is used depending on whether the normal center part is to be cleaned or the corner part is to be cleaned. It is a nozzle.

Next, a second embodiment and a third embodiment of the present invention will be described with reference to FIGS. In the second embodiment, as shown in FIG. 2, a front sub suction chamber 34 is provided only in the front of the suction chamber 25. In the third embodiment, as shown in FIG.
The side sub suction chamber 35 is provided only on the side of the. Further, in these embodiments, as shown in FIG. 4, the switching between the passages of the sub-opening 32 and the opening 26 is performed by the switching means 37 provided in the opening 26. That is, the opening 26 is closed and the passage of the sub-opening 32 is opened by rotating the partition plate constituting the switching means 37 about the rotating shaft 37a.

In the second embodiment of the present invention, only the front auxiliary suction chamber 34 is provided.
When the main body 21 is pressed against the wall, a very large suction force is generated at the front part. That is, it is particularly effective when the user cannot perform an operation of moving the main body 21 left and right. In the third embodiment of the present invention, since only the side auxiliary suction chamber 35 is provided, the corners can be easily cleaned simply by moving the main body 21 along the wall.

Next, a fourth embodiment of the present invention will be described with reference to FIG. In this embodiment, the switching of the switching means 36 for switching the passage between the sub-opening 32 and the opening 26 described with reference to FIG. 1 is realized by the switch 38 provided on the bumper 22. As the switch 38,
In this embodiment, for example, a very light touch device such as a membrane switch or a micro switch is provided on the lower main body member 24 inside the bumper 22, and is used at a total of three places on both sides of the main body 21 and the front portion. I have. This may be one or two places depending on the formation position of the auxiliary suction chamber.

As described above, in the case of FIG. 1, the passage between the sub-opening 32 and the opening 26 is switched by the bumper 22.
In conjunction with the switch 38 provided in the first embodiment. That is, when the user is cleaning the room and the bumper 22 of the main body 21 comes into contact with a wall or the like, the switch 38 at the contacted position is automatically operated, the switching means 36 is operated, and the sub opening 32 is opened. The mode is switched to the corner cleaning mode to be used. Accordingly, a floor nozzle for a vacuum cleaner having very good usability is realized. The same applies to the switching means 37.

[0024]

According to the first means of the present invention, a sub suction chamber is provided separately from the suction chamber, and these are switched by the switching means, so that a sufficient suction force can be exerted even when cleaning the corner. And a floor nozzle for a vacuum cleaner having excellent usability.

The second means of the present invention realizes a floor nozzle for an electric vacuum cleaner in which the auxiliary suction chamber is provided particularly on the front face of the main body, and particularly, the front face of the main body can be easily cleaned.

The third means of the present invention realizes a floor nozzle for an electric vacuum cleaner in which the auxiliary suction chamber is provided on both side surfaces of the main body, and particularly, the side surface of the main body can be easily cleaned.

According to the fourth means of the present invention, in particular, the switching means is constituted by a partition plate provided at the opening, so that the simple structure can be used for cleaning the center of the room and cleaning the corner of the room. The floor nozzle for a vacuum cleaner that can be easily used according to the situation can be obtained.

In the fifth means of the present invention, particularly, the switching means is switched by a switch provided on the main body, so that a cleaning mode suitable for the center portion and a cleaning mode suitable for the corner portion can be automatically used properly. An object of the present invention is to provide a floor nozzle for a vacuum cleaner which is very easy to use.
