Input / output means. The communication between the cleaning unit 3 and the main body 2 includes:
As described above, two power lines of the commercial power supply are used.
The two power lines 21 are connected from the main body 2 to the pipe / insertion port 1.
・ Power via hose 3a, hand operation unit 3b and extension tube
-Wired to nozzle 4. The operation of this embodiment will be described below. The user
Select the outlet 1 installed in the cleaning place and select the cleaning unit 3
And a switch (not shown) provided in the input / output means 22.
When the power is turned on, power is supplied to the cleaning unit 3. this
Time, handSwitching settingshandStep 9Switched to receiving side.
Then, the fan motor 19 and the power nozzle 4 are stopped.
I have. The hand control means 7 inserts the cleaning unit 3 into the insertion port 1
After detecting that the user has
The specified input content and the content detected by the garbage amount detection means 10 are
Read the number of rotations of the power nozzle 4 and the fan motor 1
The number of rotations of 9 is determined. And the number of rotations of the power nozzle 4
The control content is output to the power nozzle driving means 11. [0012] The content of the control of the rotation speed of the fan motor 19
Is transmitted from the local transmission means 5 to the main body 2 via the power line 21.
Can be At this time, the hand control means 7 sets the signal to be transmitted to
And a hand synchronization signal and a fan motor phase control signal.
The signal is defined by a certain message length. And these two
The message is sent to the on-hand procedure setting means 8. Receiving these two messages
The order setting means 8 transmits the message to each message.
Set the number. In other words, the first synchronization signal is
No. 2 in the data phase control signal. Signals according to this order
Is transmitted. At the same time, the local procedure setting means 8
The order ofSwitching settingsSend to means 9. According to this content
And at handSwitching settingsMeans 9 switches to the transmitting side. Soshi
When the transmission of these two signals ends,Switching settings
Means 9 is switched to the receiving side and the bookBody 2Reception of these signals
Wait for. The signal transmitted from this hand is the main body receiving means 1
2 is received. The main body receiving means 12 is a main body.Switching settingsMeans 16
Has been switched to the receiving side in advance,
1. Receive the signal on line 21. Then, this received signal is
Processed by the body control means 14 and processed by the body control means 14
The driving time of the fan motor 19 based on the phase control means 1
8 as a result, and as a result, output from the phase control means 18
Control the fan motor driving means 20 based on the
The number of rotations of the fan motor 19 is controlled. This is the fan
The motor 19 and the power nozzle 4 start operating. This hand
The main body control means 14, which has received the original signal,
Notify the main body procedure setting means 15 and receive the book
Body procedure setting means 15 is a main bodySwitching settingsMeans 16 to sender
Switch. [0014] The dust collected by cleaning is inspected for dust amount.
The informing means 17 detects the information, and the information on the amount of dust is
The power is transmitted from the stage 14 to the cleaning unit 3 via the power line 21.
Also at this time, the two signals of the main body synchronization signal and the dust amount signal
It is determined by a certain message length. And these two electricity
The body procedure setting means 15 having received the sentence sends the message to each message.
Determine the order of communication. That is, the body synchronization signal is number 3,
No. 4 in the dust amount signal. Send signals in this order.
I believe. At the same time, the main body procedure setting means 15
The bodySwitching settingsSend to means 16. According to this content,
bodySwitching settingsMeans 16 switches to the transmitting side. And this
When the transmission of the two signals ofSwitching settingsMeans 1
6 switches to the receiving side and waits for reception of a signal from the hand.
One. The transmitted dust amount data is decoded by the hand control means 8.
The data is output to the input / output means 22. As shown in FIG. 2, a signal is held between the hand and the main body.
And repeat signal transmission and reception according to that order.
And at regular intervals. As a result, the user has to clean
The current amount of dust can be grasped.Said
At the same time that power is supplied to the cleaning unit 3,
The transmission and reception with the cleaning unit 3 is a cycle as shown in FIG.
It is always done in. The user operates the input / output unit 22 to set the fan
When the input of the motor 19 is changed, the contents of the input are controlled locally.
The control means 7 reads. And the hand control means 7
Fan motor phase control signal changed at transmission timing
Is transmitted to the main unit 2. This transmitted fan motor phase
The control signal is then input by the user through the input / output
This is continued until the input of the data 19 is changed. Also, the main body
2 sends the dust amount data to the cleaning unit 3 side.
You. In this embodiment, the signal is transmitted to the power line at the commercial frequency.
Power line carrier communication superimposed at a sufficiently high frequency
The method of performing communication between the main body 2 and the cleaning unit 3 has been described.
However, other methods such as ultrasonic, optical, wireless, etc. may be used.
No. The point is that the power is transmitted for signal communication between the main unit 2 and the cleaning unit 3.
If the method does not use wires other than the power line 21,good. [0017] According to the present invention,By the lightIf it is a power line
Synchronize by superimposing a signal with a frequency sufficiently higher than the commercial frequency
Half duplex communication is synchronized with the signal.
Therefore, only two power lines can be used.
It can shorten the time of things and eliminate misconnections
You.
