Abstract

PROBLEM TO BE SOLVED: To provide a vacuum cleaner capable of controlling the drive of an electric fan easily without increasing the weight by detecting the condition of cleaning, the condition of the suction hole touching the floor, and the cleaning movement. SOLUTION: A condition detecting means 28 for detecting the condition of the suction body touching the floor is attached to the suction body of this vacuum cleaner. The suction body is connected to a hand control part of a hose connected to the vacuum cleaner main body 1, in which an electric fan 6 is stored, by way of an extension pipe. A signal transmitting means 39 is connected to the condition detecting means 28, which transmits a prescribed signal by means of a radio medium 38 when detects that the suction body 11 is not touching the floor surface. A circuit base board and a signal receiving means 41 for receiving signals from the signal transmitting means 39 are mounted inside the vacuum cleaner main body 1, and a control means 37 for controlling the drive of the electric fan 6 is mounted on the circuit base board. When the suction body 11 is not in contact with the floor surface because the cleaning operation is suspended, a prescribed signal is transmitted/received by means of the radio medium 38, and the drive of the electric fan 6 is temporarily stopped by the control means 37. Therefore, no transmission line for transmitting the condition of the suction body touching the floor surface is required in the hose nor in the extension pipe, so that the vacuum cleaner can be lightweight and small-sized, can be more easily manufactured and the cleaning operation will be easier.

Next, the internal configuration will be described with reference to FIGS.

The electric blower 6 housed in the vacuum cleaner main body 1 is connected to a commercial AC power supply E via a power cord (not shown) and a power control triac 35.

The gate of the triac 35 is connected to a control means 37 mounted on a circuit board 36 built in the vacuum cleaner main body 1 and controlling the driving of the electric blower 6.

On the other hand, a state detecting means 28 is provided in the suction port body 11, and when a switch section 31 is turned on, a predetermined signal is transmitted by a wireless medium 38 such as a sound wave or a radio wave infrared ray. The transmitting means 39 for transmitting is transmitted. The state detecting means 28 and the transmitting means 39 are connected to a power supply (not shown) such as a dry battery or a storage battery for supplying power.

Further, an operation means 42 is connected to the control means 37, and the operation means 42 differs depending on the operation of the stop setting button 15, the weak setting button 16, the middle setting button 17, and the strong setting button 18. Outputs the current of the current value.

Next, the operation of the above embodiment will be described with reference to the flowchart shown in FIG.

First, the hose 8, the extension tube 10, and the suction port 11 are connected to the main body 1 of the vacuum cleaner, and a commercial AC power supply E is supplied through a power cord (not shown) to enter a cleaning standby state. The control unit 37 detects the current from the operation unit 42 in the cleaning standby state. When the current value of the current to be detected is 0, the interval between the two transmission lines (not shown) for transmitting the signal of the operating means of the hose 8 is open.
It is determined that the hose 8 has come off and is not in the cleaning standby state.

The control means 37 detects a current value exceeding a predetermined threshold, that is, the hose 8 is connected and the operation means 42
It is determined whether or not any of the predetermined buttons 16, 17, 18 has been operated (step 1), and the control means 37 detects a current value exceeding a predetermined threshold value, and responds to the detected current value. To control the input voltage supplied to the electric blower 6 in accordance with a predetermined driving state (step 2). The supply of the input voltage drives the electric blower 6 in a predetermined driving state, and for example, pushes the grip 13 of the hose 8 in the front-rear direction so that the suction opening body 11 runs on the floor surface 25 which is the surface to be cleaned. Or pull and clean. This electric blower 6
Dust is sucked together with air from the suction port 20 opened on the lower surface of the suction port body 11, and guided to the dust collection chamber (not shown) of the vacuum cleaner main body 1 via the extension pipe 10 and the hose 8. Captured in the bag. The air filtered by the dust bag passes through the electric blower 6 from an intake port (not shown) of the electric blower 6 and passes through the exhaust port to the electric vacuum cleaner main body 1.
Exhaust air is discharged to the outside air.

Then, the control means 37 determines whether or not the receiving means 41 has detected the signal transmitted from the transmitting means 39, that is, whether or not the signal indicating that the suction port body 11 has not landed is received. Is determined (step 3).

Here, the state detecting means 28 causes the case body 22 to move the suction port body 11 on the floor surface 25 by the cleaning operation of moving the suction port body 11 on the floor surface 25.
25, the rotating body 29 contacts the floor surface 25 and the case body 22
The rotating member 30 is rotated so as to retreat inward, is in contact with the switch unit 31, and is turned on. And
A signal indicating that the suction port body 11 has landed and is in a cleaning mode is transmitted from the transmission means 39 of the suction port body 11, that is, the suction port body 11
Does not transmit a predetermined signal indicating that it is separated from the floor surface 25 and is not in the landing state. For this reason, the control means 37 determines that the receiving means 41 has not received a signal from the transmitting means 39 indicating that the suction port body 11 has not landed, and sets the electric blower 6 to the setting operation of the operating means 42 described above. (Step 4), and the process returns to Step 1.

In step 3, the control means 37 receives a signal from the transmitting means 39 indicating that the suction port 11 is not landing on the receiving means 41, so that the suction port 11 is moved from the floor surface 25. The switch unit 31 of the state detecting means 28 is open when separated, that is, by placing the hose 8 on the floor surface 25 by moving furniture, lifting the hose 8 for moving a cleaning place, or the like, It is determined that the cleaning in which the lower surface of the suction opening 11 is separated from the floor surface 25 has been interrupted or stopped, and the driving of the electric blower 6 is temporarily stopped (step 5).
Return to

On the other hand, in step 1, a current value exceeding a predetermined threshold value due to operation of the predetermined button 16, 17, 18 of the operating means 42 is not detected, that is, a current value exceeding the predetermined threshold value is not detected. If not, it is determined whether or not a current value of a predetermined threshold value due to the operation of the stop button 15 of the operation means 42 has been detected (step 6). When the control means 37 determines that the current value of the predetermined threshold value by the operation of the stop button 15 has been detected, the driving of the electric blower 6 is completely stopped (step 7), that is, the operation means 42 again. Unless an operation to drive the electric blower 6 is performed by the setting operation of the electric blower 6,
Stops in a non-driving state. Also, in step 6,
When the control means 37 determines that the current value of the predetermined threshold value due to the operation of the stop button 15 is not detected, it is determined whether the electric blower 6 is driven or is in a pause state (step 8). . If the electric blower 6 is driven or temporarily stopped, the process proceeds to step 3, and if it is determined that the electric blower 6 is not driven or temporarily stopped, that is, it is completely stopped, for example, noise or the like It is determined that an abnormal current has occurred, and the process returns to step 1.

When the cleaning is restarted again, that is, when the suction port 11 is landed again in the state where the suspension has been performed in step 5, the control means 37 causes the receiving means 41 to transmit the signal to the receiving means 41 in step 3. When it is determined that the signal indicating that the suction port body 11 has not landed has not been received from 39, for example, the drive control is performed to the drive state immediately before the temporary stop, or the electric blower 6 is restarted in a predetermined state such as inside. Drive control.

As described above, the state detecting means 28 provided on the suction port body 11 detects that the suction port body 11 has not landed on the floor surface 25, thereby transmitting the signal from the transmission means 39 to the wireless medium 38. Receiving means for receiving the predetermined signal from the vacuum cleaner main body 1
When received at 41, the control means 37 stops the operation of the electric blower 6 based on the received signal. The electric blower 6 can be driven and controlled without using a lead wire or the like for transmitting a signal in a state detected by the detection means 28 to the circuit board 22 on which the control means 37 is mounted, and the hose 8 and the extension pipe 10 can be reduced in weight and manufactured. Performance can be improved. Therefore, the suction port body 11 is held on the floor surface 25 by holding the hose 8.
The cleaning operation such as running on the upper side becomes easy, the cleaning workability can be improved, and the electric blower 6 can be prevented from being driven unnecessarily in a state where the suction port body 11 is floating, and energy can be saved.

Further, the electric blower 6 is temporarily stopped after receiving a signal indicating that the suction port 11 detected by the state detecting means 28 has not landed on the floor surface 25, and then returns to the state. Is detected by the receiving means 41, the drive of the electric blower 6 is controlled again in a predetermined drive state.
There is no need to re-operate the setting operation of 42, and the cleaning workability can be improved.

In the above embodiment, the rotating body 29
The landing state of the suction port body 11 is detected by using the state detection means 28 having the rotating member 30 having a rotation member 30. Using a rolling sensor as a cleaning operation detecting means having a sphere rolling on the top and detecting a cleaning operation as a state detecting means 28, the cleaning operation is detected by recognizing that the electrodes are turned on and off within a predetermined time. In response to this cleaning operation, a predetermined signal is transmitted / received to drive and control the electric blower 6, that is, if the electrodes are not turned on / off for a predetermined time or longer, it is determined that the cleaning has not been performed and the cleaning operation cannot be detected. Drive control for stopping the drive of the electric blower 6 or reducing the input may be performed.

Further, a structure for detecting a landing state and a structure for detecting a cleaning operation such as a rolling sensor may be used together. And by using them together, it is possible to more reliably determine whether or not cleaning is being performed, and more appropriate control can be performed.

In the above description, when the suction port 11 is not on the floor, the electric blower 6 is temporarily stopped. However, for example, the electric blower 6 is set to a driving state lower than weak. May be reduced.

Furthermore, when the suction port body 11 has not landed, the electric blower 6 is temporarily stopped, and when it has landed again, the drive is controlled to a predetermined driving state. In this state, the electric blower 6 may be completely stopped, and the driving of the electric blower 6 may not be restarted unless the setting operation is performed by the operation means 42 again. According to this configuration, it is possible to prevent a malfunction in which the electric blower 6 is driven in spite of the interruption, by erroneously recognizing the landing state due to vibration or the like during the interruption of the cleaning.

On the other hand, operating means is provided on the hand operating section 12 of the hose 8.
Although the description has been made with the arrangement of the 42, for example, as shown in FIG. 7, the operating means 42 may be arranged on the vacuum cleaner main body 1. According to this configuration, it is not necessary to arrange a transmission line for flowing a current of a predetermined current value by the setting operation of the operation means 42 in the hose 8, and the hose 8 can be further reduced in weight and productivity can be improved.

Further, by controlling the electric blower 6 to a predetermined driving state or controlling the stop of the electric blower 6 according to the landing state or the cleaning operation by the state detecting means 28, for example, as shown in FIG. Can be configured not to be provided on the hose 8 or the vacuum cleaner main body 1, and the structure can be simplified, the productivity can be improved, and the weight and size can be reduced.
