A second means of the present invention for achieving the second object is that the switching device constituting the first means of the present invention is a floor nozzle for a vacuum cleaner of a manual type.

A third means of the present invention for achieving the third object is to provide a floor nozzle for a vacuum cleaner which utilizes a motor force in the switching device constituting the first means of the present invention.

The fourth means of the present invention for achieving the fourth object is to provide a first suction port provided at the center of the main body, a second suction port provided at the tip of the main body, and a proximity sensor.
The floor nozzle for a vacuum cleaner has a switching device that switches between the two suction ports according to the information from the proximity sensor.

[0010]

[Operation] The first means of the present invention operates so that the suction port switching device selectively switches between the first suction port provided at the center of the main body and the second suction port provided at the tip of the main body. It is a thing.

The second means of the present invention is to manually operate the suction port switching device. A third means of the present invention is to operate the suction port switching device by a motor. The fourth means of the present invention is such that the proximity sensor provided at the tip of the floor nozzle detects the presence of an obstacle and automatically switches the suction port switching device to the second suction port. is there.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A floor nozzle for a vacuum cleaner according to a first embodiment of the present invention (hereinafter simply referred to as a floor nozzle) will be described below with reference to FIG. In the center of the body 1 is a first suction port 2
The second suction port 3 is provided at the tip. Further, 4 is a switching device composed of gears, levers, etc., which switches the ventilation path leading to the first suction port 2 and the second suction port 3. In this embodiment, the switching device 4 is provided with a manual switching switch 5 operated by the user.

The operation of this embodiment will be described below. When the user operates the manual switching switch 5 of the switching device 4, the ventilation path is switched from the first suction port 2 to the second suction port 3 or from the second suction port 3 to the first suction port 2. It is a thing. That is, by operating the manual changeover switch 5 according to the situation of the cleaning place, the first suction port 2 and the second suction port 3 can be selectively used. In this case, the first suction port 2 is located in the central portion of the main body 1, has a wide suction range, and is suitable for cleaning the central portion of the room. The second suction port 3 is located at the tip of the main body 1 and is suitable for cleaning a corner of a room or the vicinity of an obstacle. At this time, if the suction speed of the second suction port 3 is set to be faster than the suction speed of the first suction port 2, the suction force becomes strong, and it becomes possible to suck in dust that is difficult to suck.

In this embodiment, the second suction port 3
Although the installation position is on the upper left side as shown in FIG. 1, it is also possible to install a third suction port on the upper right side to suck in the dust on the right side, It is also possible to absorb the dust.

As described above, according to this embodiment, by freely using the first suction port 2 and the second suction port 3, it is possible to eliminate the gap nozzle that was conventionally required for cleaning the corners of the room. The floor nozzle for a vacuum cleaner is easy to use and does not need to be used.

Next, the second embodiment of the present invention will be described with reference to FIG.
It will be described based on. 6 is a suction port switching device, 7
Is a motor for driving an agitator (not shown), which acts as a drive source of the changeover switch 6 based on a command from a hand switch (not shown) in this embodiment. That is, the motor 7 switches the ventilation path leading to the first suction port 2 and the second suction port 3.

With the above structure, the user operates the hand switch according to the situation of the cleaning place to operate the motor 7, so that the first suction port 2 and the second suction port 3 can be used separately. It can be done.

Next, the third embodiment of the present invention will be described with reference to FIG.
It will be described based on. Reference numeral 8 is a proximity sensor using an optical sensor, ultrasonic waves, etc., which detects the presence of obstacles such as furniture such as walls and chests in the room. The suction port switching device 6 receives the information from the proximity sensor 8 and receives the information from the motor 7
To operate the first suction port 2 and the second suction port 3
To switch the ventilation path to.

With the above construction, the proximity sensor 8 constantly detects the presence or absence of an obstacle and transmits this information to the suction port switching device 6. Therefore, when approaching furniture such as a corner of a room or a closet, the ventilation path is automatically switched to the second suction port 3. When the obstacle moves away, the ventilation path is automatically switched to the first suction port 2 again.

[0020]

According to the first means of the present invention, the first suction port provided at the center of the main body, the second suction port provided at the tip of the main body, and the switching device for switching the two suction ports. As a configuration having the above, it is possible to provide a floor nozzle for a vacuum cleaner that is easy to use even when cleaning a corner of a room or the vicinity of furniture such as a closet.

The second means of the present invention provides a concrete means in which the switching device constituting the first means of the present invention is of a manual type, and can be a floor nozzle for a vacuum cleaner which is easy to use. It is a thing.

The third means of the present invention provides a concrete means in which the switching device constituting the first means of the present invention is of a motor type, and can be a convenient floor nozzle for a vacuum cleaner. It is a thing.

The fourth means of the present invention is to provide a first suction port provided at the center of the main body, a second suction port provided at the front end of the main body, a proximity sensor, and the two of the above two types based on information from the proximity sensor. As a configuration having a switching device for switching the suction port, it is possible to provide a convenient floor nozzle for a vacuum cleaner that does not require the user to perform the switching operation.
