Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner characterized by control of the vacuum cleaner body or floor nozzle section.

Conventional technology Conventionally, in vacuum cleaners, the power nozzle in the floor nozzle section is turned on or off by operating signals from the hand control section.
Alternatively, the output of the suction air volume motor inside the vacuum cleaner body is controlled. This required a plurality of ACioov electric wires and signal lines in the pipe section connecting the hand control section and the floor nozzle section, and the hose section connecting the hand control section and the vacuum cleaner body.

Problems to be Solved by the Invention With such a structure, a plurality of electric wires must be provided in the pipe portion or the hose portion, which is very time-consuming and has poor productivity.

The present invention has solved the above-mentioned conventional problems, and its first object is to control a power nozzle with less wiring by using ultrasonic waves. The second purpose is to control the vacuum cleaner body according to the air volume with a small amount of wiring using ultrasonic waves. includes a vacuum cleaner body, a floor nozzle portion having a power nozzle,
and a hand-held operating section for controlling the power nozzle, the hand-held operating section is provided with an ultrasonic transmitting means for emitting ultrasonic waves in response to an operating signal, and the floor nozzle section is provided with an ultrasonic wave emitting means emitted from the ultrasonic transmitting means. The apparatus includes an ultrasonic receiving means for receiving the ultrasonic signal and a control means for controlling the power nozzle based on the received ultrasonic signal.

In order to achieve the second object, the vacuum cleaner of the present invention includes a vacuum cleaner main body, a floor nozzle section, and a hand control section for operating the vacuum cleaner main body, and the hand control section has air volume settings. An ultrasonic transmitter is provided that emits ultrasonic waves at a period corresponding to the
The vacuum cleaner main body includes an ultrasonic receiving means for receiving the ultrasonic waves emitted from the ultrasonic transmitting means and a control means for controlling the vacuum cleaner main body to an air volume according to a reception signal of the ultrasonic receiving means. It is something.

Operation With the above configuration, since ultrasonic waves are used, there is only a small amount of wiring required between the hand-held operating section and the floor nozzle section, and the power nozzle can be controlled using the hand-held operating section.

The same applies between the hand control unit and the vacuum cleaner body.
The air volume of the vacuum cleaner body can be controlled by emitting ultrasonic waves at a cycle according to the air volume setting.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 1 to 3 show the first embodiment,
1 is a vacuum cleaner body equipped with a suction air volume motor, 2
4 is a floor nozzle section having a power nozzle 3; 4 is a hand control section that controls the vacuum cleaner main body 1 and the power nozzle 3; 5 is a hose section that connects the vacuum cleaner main body 1 and the hand control section 4; 6 is a floor nozzle section. 2 and the hand-held operating section 4. For example, in the above-mentioned hand-operated unit 4, "automatic" or "
It can be operated in a manner other than automatic, and is provided with ultrasonic transmitting means 7 that emits ultrasonic waves in response to this operation signal. Further, the floor nozzle section 2 includes an ultrasonic receiving means 8 that receives the ultrasonic waves emitted from the ultrasonic transmitting means 7, a control means 9 that controls the power nozzle 3 based on the received ultrasonic signals, and It has a floor surface determining means 10 which determines whether the floor surface is carpet or something else and sends a signal to the control means 9.

Next, the operation of the vacuum cleaner described above will be explained. The floor surface determination means 10 constantly determines the condition of the floor surface and outputs the determination result to the control means 9.

The output signal is, for example, "H" if it is carpet, and "L" if it is other than that (tatami, floor).

If the user now sets "automatic" using the hand-held operation unit 4, the ultrasonic transmitting means 7 outputs ultrasonic waves of a predetermined frequency into the pipe section 6. The output ultrasonic waves pass through the pipe section 6 and reach the floor nozzle section 2. This signal is sent to the floor nozzle section 2.
The ultrasonic wave receiving means 8 provided within receives the ultrasonic waves, and the control means 9
sends a detection signal to. Control means 9 to which the detection signal is sent
When confirming this detection signal, it recognizes that the operation is "r automatic" and determines the operation of the power nozzle 3 based on the output of the floor surface determining means 10. That is, when the signal from the floor surface determining means 10 is "L", the power nozzle 3 stops, and when the signal is "H", the output of the operation is transmitted to the ultrasonic receiving means 8.
The control means 9 outputs an output to the power nozzle 3 only when there is a detection signal from the power nozzle 3. This makes it possible to clean the inside of the carpet while knocking out the dirt.

When the user sets "other than automatic" on the hand-held operation unit 4, the ultrasonic wave transmitting means 7 does not transmit ultrasonic waves. Therefore, the ultrasonic wave receiving means 8 does not receive ultrasonic waves and does not output a detection signal to the control means 9. On the other hand, the control means 9
Since there is no detection signal from the ultrasonic receiving means 8, the floor surface determination means 10 determines that the state of the floor surface is carpet and indicates "H".
A stop signal is output to the power nozzle 3 even if the signal is output.

Next, a second embodiment of the present invention will be described based on FIGS. 4 to 6. The same parts as those in the first embodiment are given the same reference numerals and detailed explanations will be omitted. The hand operation section 4 is provided with an operation section 20 for setting the air volume, a control section 22 for controlling the timer means 21 according to the operation signal thereof, and an ultrasonic transmitting means 23 for emitting ultrasonic waves at the set period of the timer means 21. ing. The ultrasonic transmitting means 2 is provided in the vacuum cleaner body 1.

, a control means 26 for controlling the suction air volume motor 25 in the vacuum cleaner main body to an air volume according to the reception signal of the ultrasonic reception means 24;
It has the following.

Next, the operation of this embodiment will be explained. The user sets the air volume using the operation section 20 of the hand-held operation section 4 (for example, (strong)).
>, the control unit 22 and the timer means 21 control the control unit 22 and the timer means 21 to set a predetermined cycle (“L” for 20 m 8 intervals) according to the set air volume.
The ultrasonic transmitting means 23 emits ultrasonic waves into the hose part 5 (for example, 20 m S for each of (strong), (standard), and (weak), 5 m for every 40 m, and 5 m for every 60 m5.
mS output). The emitted ultrasonic waves pass through the hose portion 5 and reach the cleaner body 1. Here, the ultrasonic receiving means 24 in the main body sends "H" as an output signal when it receives this ultrasonic wave, and "L" when it does not receive it as an output signal to the control means 26 (that is, when there is an ultrasonic signal) ``H'' if there is no ultrasonic signal, ``L'' if there is no ultrasonic signal). The control means 26 determines how many ms the output signal from the ultrasonic receiving means 24 is "L" and how many ms it is "H". In other words, it is "L" for 20 m for 5, "H" for 5 m and 8 (hard), and "L" for 40 m for 8,
If it is "H" for 5mS (standard), it is determined to be "L" for 60m5, and if it is "H" for S m 8 (weak). The control means 26 sends a signal (for example (strong)) to the suction air volume motor 25 to operate it.

Effects of the Invention As mentioned above, the vacuum cleaner of the present invention sends information using ultrasonic waves, so only two AC 100V electric wires are required between the hand control unit and the floor nozzle, which is very inexpensive and highly productive. Can be a good vacuum cleaner.
