Embodiment 1 FIG.
FIG. 1 is a perspective view of the electric vacuum cleaner according to Embodiment 1 of the present invention. FIG. 2 is a schematic longitudinal sectional view of the electric vacuum cleaner according to Embodiment 1 of the present invention.

  As shown in FIGS. 1 and 2, the electric vacuum cleaner includes a main body 1, an extension tube 2, and a suction attachment 3. The said vacuum cleaner is a cordless type vacuum cleaner.

  The main body 1 includes a main body suction port 4, a cyclone unit 5, a dust collection unit 6, and an exhaust port 7.

  The main body 1 includes a battery 8, an electric blower 9, a hand operating unit 10, a pair of main body suction port electrodes (not shown), and a control unit 11.

  The battery 8 is built in the main body 1. The electric blower 9 is built in the main body 1. The electric blower 9 includes a motor (not shown). The hand operating unit 10 is provided on the outer surface of the main body 1. The hand operation unit 10 includes a switch unit 10a and a notification unit 10b. The hand operating unit 10 is electrically connected to the control unit 11. The hand operation unit 10 transmits an external operation to the control unit 11 via the switch unit 10a. In addition, the hand operation unit 10 lights or blinks the notification unit 10 b based on a signal from the control unit 11. A pair of main body suction port electrodes is provided in the main body suction port 4. The control unit 11 is built in the main body 1. The control unit 11 is electrically connected to the hand operation unit 10 and a pair of main body suction port electrodes (not shown).

  For example, the extension pipe 2 is formed in a straight line shape. The extension tube 2 is formed in a cylindrical shape. One end of the extension tube 2 is detachably attached to the main body suction port 4. The other end of the extension tube 2 serves as a suction port. The extension tube 2 includes a pair of first electrodes (not shown), a pair of second electrodes (not shown), and a pair of electric wires (not shown).

  The pair of first electrodes is provided at one end of the extension tube 2. The pair of first electrodes are electrically connected to the pair of main body suction port electrodes when one side of the extension tube 2 is attached to the main body suction port 4. The pair of second electrodes is provided at the other end of the extension tube 2. The pair of electric wires is built in the extension pipe 2. One end portions of the pair of electric wires are electrically connected to the pair of first electrodes. The other ends of the pair of electric wires are electrically connected to the pair of second electrodes.

  The suction attachment 3 is detachably provided to the other end portion of the extension tube 2. The suction attachment 3 includes an attachment suction port 12. The attachment suction port 12 is formed on one surface of the suction attachment 3. The attachment suction port 12 opens outward.

  The attachment suction port 12, the suction attachment 3, the extension pipe 2, the main body suction port 4, the cyclone unit 5, the electric blower 9, and the exhaust port 7 form a continuous air path.

  The battery 8 supplies power to the electric blower 9 and the control unit 11. When the hand operation unit 10 receives an operation from the outside, the control unit 11 operates the electric blower 9. For example, when an “ON / OFF button” that is a part of the switch unit 10 a is pressed, the control unit 11 operates the electric blower 9 based on the set condition. When the electric blower 9 operates, suction air is generated.

  The attachment suction port 12 is directed to the surface to be cleaned. For example, the attachment suction port 12 is directed to the floor surface. At this time, dust on the surface to be cleaned is sucked into the attachment suction port 12 by suction air. The dust passes through the inside of the suction attachment 3, the inside of the extension pipe 2, and the inside of the main body suction port 4 together with the air and reaches the cyclone unit 5. The dust is separated from the air in the cyclone unit 5. The dust is accumulated in the dust collecting unit 6. On the other hand, the air passes through the electric blower 9 and is discharged from the exhaust port 7 to the outside of the main body 1.

Next, a specific example of the suction attachment 3 will be described with reference to FIG.
FIG. 3 is a circuit diagram of the suction attachment for the electric vacuum cleaner according to Embodiment 1 of the present invention.

  FIG. 3A shows a suction attachment 3 suitable for the floor surface. The suction attachment 3 suitable for the floor surface includes a pair of attachment electrodes 13a, a rotating brush 14, a brush motor 15, an attachment determination resistor 16a, and a mechanical switch 17.

  The pair of attachment electrodes 13a is provided on the connection surface with the extension tube 2 (not shown) in FIG. The pair of attachment electrodes 13 a is electrically connected to the control unit 11 via the pair of second electrodes of the extension tube 2, the pair of electric wires, the pair of first electrodes, and the pair of body suction port electrodes of the body 1. .

  The rotary brush 14 is formed in a columnar shape or a spiral shape. The rotating brush 14 includes a cleaning body (not shown). The cleaning body is formed in a hair shape. The cleaning body is planted on the rotating brush 14. The brush motor 15 is provided inside the suction attachment 3 suitable for the floor surface. The brush motor 15 has two electrical connection points. One side of the electrical connection point of the brush motor 15 is electrically connected to one of the attachment electrodes 13a. The rotating brush 14 rotates following the rotation of the rotating part of the brush motor 15.

  The attachment determination resistor 16a is provided inside the suction attachment 3 suitable for the floor surface. The attachment determination resistor 16a has two electrical connection points. One side of the electrical connection point of the attachment determination resistor 16a is electrically connected to one of the attachment electrodes 13a.

  The mechanical switch 17 is provided inside the suction attachment 3 suitable for the floor surface. The mechanical switch 17 includes a first contact 17a, a second contact 17b, a third contact 17c, and a movable part (not shown). The first contact 17a is electrically connected to the other of the attachment electrode 13a. The second contact 17 b is electrically connected to the other side of the electrical connection point of the brush motor 15. The third contact 17c is electrically connected to the other side of the electrical connection point of the attachment determination resistor 16a. The movable portion protrudes outward from one surface of the suction attachment 3.

  When one surface of the suction attachment 3 is separated from the floor surface, the movable portion does not receive external pressure from the floor surface. In this case, the first contact 17 a and the third contact 17 c are electrically connected inside the mechanical switch 17. The first contact 17 a and the second contact 17 b are not electrically connected inside the mechanical switch 17. The second contact 17b and the third contact 17c are not electrically connected inside the mechanical switch 17.

  At this time, the control unit 11 controls the battery 8 itself, the pair of main body suction port electrodes, the pair of first electrodes of the extension tube 2, the pair of electric wires, the pair of second electrodes, and the pair of attachment electrodes 13a. Power is supplied to the attachment determination resistor 16a via the mechanical switch 17. As a result, a current corresponding to the resistance value of the attachment determination resistor 16a flows in the electric wire inside the suction attachment 3.

  When one surface of the suction attachment 3 is in contact with the floor surface, the movable portion receives an external pressure from the floor surface. In this case, the first contact 17 a and the second contact 17 b are electrically connected inside the mechanical switch 17. The first contact 17 a and the third contact 17 c are not electrically connected inside the mechanical switch 17. The second contact 17b and the third contact 17c are not electrically connected inside the mechanical switch 17.

  At this time, the control unit 11 controls the battery 8 itself, the pair of main body suction port electrodes, the pair of first electrodes of the extension tube 2, the pair of electric wires, the pair of second electrodes, and the pair of attachment electrodes 13a. Electric power is supplied to the brush motor 15 via the mechanical switch 17. The brush motor 15 is rotated by the electric power. At this time, the cleaning body scoops up fine dust that has entered the gap between the carpet or flooring placed on the floor. As a result, fine dust is easily sucked into the attachment suction port 12 (not shown in FIG. 3A).

  Note that the suction attachment 3 may be directly connected to the main body suction port 4 of the main body 1 without using the extension tube 2. In this case, the pair of attachment electrodes 13 a is electrically connected to the control unit 11 via the pair of body suction port electrodes of the body 1.

  FIG.3 (b) shows the attachment 3 for suction suitable for a futon. The suction attachment 3 suitable for the futon includes a pair of attachment electrodes 13b and an attachment determination resistor 16b.

  The pair of attachment electrodes 13b is provided on the connection surface with the extension tube 2 (not shown) in FIG. The pair of attachment electrodes 13b is electrically connected to the control unit 11 via the pair of second electrodes of the extension tube 2, the pair of electric wires, the pair of first electrodes, and the pair of body suction port electrodes of the body 1. . The attachment determination resistor 16b is provided inside the suction attachment 3 suitable for the futon.

  The control unit 11 supplies power to the attachment determination resistor 16b from the battery 8 through the self, a pair of main body suction port electrodes, and the pair of attachment electrodes 13b under its own control. As a result, a current corresponding to the resistance value of the attachment determination resistor 16 b flows in the electric wire inside the suction attachment 3.

  Note that the suction attachment 3 may be directly connected to the main body suction port 4 of the main body 1 without using the extension tube 2. In this case, the pair of attachment electrodes 13 b is electrically connected to the control unit 11 via the pair of body suction port electrodes of the body 1.

Next, the control unit 11 will be described with reference to FIG.
FIG. 4 is a schematic block diagram of the electric vacuum cleaner according to Embodiment 1 of the present invention.

  The control unit 11 includes an acceleration sensor 18, a current detection resistor 19, an electric blower control unit 20, and a microcomputer 21 (microcomputer).

  The acceleration sensor 18 is provided inside the control unit 11. The current detection resistor 19 is provided inside the control unit 11. The current detection resistor 19 is connected in series to an electric wire (not shown) that electrically connects the control unit 11 and the suction attachment 3. The electric blower control unit 20 is electrically connected between the control unit 11 and the electric blower 9.

  The acceleration sensor 18 and the microcomputer 21 function as an operation detector 22. Specifically, the microcomputer 21 determines the movement operation of the control unit 11 based on the detection result of acceleration by the acceleration sensor 18. The microcomputer 21 determines the usage state of the vacuum cleaner based on the determination result of the movement operation of the control unit 11.

  The current detection resistor 19 and the microcomputer 21 function as an attachment determination unit 23. Specifically, the microcomputer 21 determines the type of the suction attachment based on the measurement result of the current flowing from the control unit 11 to the suction attachment 3 using the current detection resistor 19.

  For example, when the “ON / OFF button” of the hand operation unit 10 is pressed, power is supplied from the control unit 11 to the suction attachment 3.

  For example, when the electric power is supplied to the brush motor 15, an inrush current instantaneously flows through the electric wire inside the suction attachment 3. The value of the inrush current is a value larger than the current in the electric wire inside the suction attachment 3 during the normal rotation of the brush motor 15.

  For example, when the power is supplied to an attachment determination resistor 16a (not shown in FIG. 4), a current flows through the current detection resistor 19. The value of the current is a value corresponding to the resistance value of the attachment determination resistor 16a.

  The microcomputer 21 outputs a control signal for the electric blower 9 to the electric blower control unit 20 based on the output signal from the switch unit 10 a, the output signal from the acceleration sensor 18, and the current flowing through the current detection resistor 19. The electric blower control unit 20 controls the output of the electric blower 9 based on the control signal.

Next, the operation of the motion detector 22 will be described with reference to FIG.
FIG. 5 is a flowchart for explaining the operation of the operation detector of the electric vacuum cleaner according to Embodiment 1 of the present invention.

  In step S <b> 1, the acceleration sensor 18 and the microcomputer 21 are supplied with power from the battery 8. Thereafter, the process proceeds to step S2. In step S <b> 2, the microcomputer 21 determines the output of the acceleration sensor 18 during a preset period R.

  When the output of the acceleration sensor 18 during the period R set in advance in step S2 is S or more, the process proceeds to step S3. In step S3, the microcomputer 21 determines that the vacuum cleaner is performing a cleaning operation. Then, it returns to step S2.

  When the output of the acceleration sensor 18 is less than S during the period R preset in step S2, the process proceeds to step S4. In step S4, the microcomputer 21 determines that the electric vacuum cleaner is not performing a cleaning operation. Then, it returns to step S2.

Next, operation | movement of the attachment determination device 23 is demonstrated using FIG.
FIG. 6 is a flowchart for explaining the operation of the attachment determination device of the electric vacuum cleaner according to Embodiment 1 of the present invention.

  Step S12 is a state in which the power source of the vacuum cleaner is OFF. If the “ON / OFF button” of the hand operation unit 10 is pressed in step S12, the process proceeds to step S13. In step S <b> 13, the microcomputer 21 supplies power to the suction attachment 3. Thereafter, the process proceeds to step S14.

  In step S <b> 14, the microcomputer 21 determines whether or not the magnitude of the current flowing through the suction attachment 3 after a certain time has elapsed is V or more. The fixed time is set as appropriate. For example, the certain time is set according to the time required for the value of the inrush current flowing through the suction attachment 3 to return to a normal value.

  When the magnitude of the current flowing through the suction attachment 3 is V or more in step S14, the process proceeds to step S15. In step S15, the microcomputer 21 determines that the connected suction attachment 3 is the “floor surface” suction attachment 3 suitable for the floor surface. The microcomputer 21 determines that one surface of the “floor surface” suction attachment 3 is in contact with the floor surface.

  When the magnitude of the current flowing through the suction attachment 3 is less than V in step S14, the process proceeds to step S16. In step S <b> 16, the microcomputer 21 determines whether the magnitude of the current flowing through the suction attachment 3 is X or more.

  When the magnitude of the current flowing through the suction attachment 3 is X or more in step S16, the process proceeds to step S17. In step S <b> 17, the microcomputer 21 determines that the connected suction attachment 3 is the “floor surface” suction attachment 3. The microcomputer 21 determines that one surface of the “floor surface” suction attachment 3 is separated from the floor surface.

  If the magnitude of the current flowing through the suction attachment 3 is less than X in step S16, the process proceeds to step S18. In step S <b> 18, the microcomputer 21 determines whether the magnitude of the current flowing through the suction attachment 3 is W or more.

  If the magnitude of the current flowing through the suction attachment 3 is greater than or equal to W in step S18, the process proceeds to step S19. In step S <b> 19, the microcomputer 21 determines that the connected suction attachment 3 is a “futon” suction attachment 3 suitable for a futon.

  If the magnitude of the current flowing through the suction attachment 3 is less than W in step S18, the process proceeds to step S20. In step S20, the microcomputer 21 determines that the suction attachment 3 is not connected.

Next, the state transition of the vacuum cleaner will be described with reference to FIG.
FIG. 7 is a flowchart for explaining state transition of the electric vacuum cleaner according to Embodiment 1 of the present invention.

  In step S21, the state of the vacuum cleaner is the first state. When the state of the vacuum cleaner is the first state, the electric blower 9 and the suction attachment 3 are not supplied with electric power. At this time, if the “ON / OFF button” is pressed, the process proceeds to step S22.

  In step S22, the state of the vacuum cleaner transitions from the first state to the second state. When the state of the vacuum cleaner is the second state, the suction attachment 3 is supplied with electric power, and the electric blower 9 is not supplied with electric power. Thereafter, the process proceeds to step S23.

  In step S23, the microcomputer 21 determines the type of the suction attachment 3 connected after a predetermined time has elapsed.

  When the suction attachment 3 connected in step S23 is the “floor surface” suction attachment 3, the process proceeds to step S24. If the suction attachment 3 is not connected in step S23, the process proceeds to step S24.

  In step S24, the state of the electric vacuum cleaner transitions from the second state to the third state after a predetermined time has elapsed. When the state of the vacuum cleaner is in the third state, the electric blower 9 and the suction attachment 3 are supplied with electric power. Thereafter, the process proceeds to step S25.

  In step S <b> 25, the microcomputer 21 determines whether the moving speed based on the output from the acceleration sensor 18 is equal to or less than the threshold value A. If the moving speed is greater than the threshold value A in step S25, step S25 is repeated. If the moving speed is equal to or lower than the threshold value A in step S25, the process proceeds to step S26.

  In step S26, the state of the vacuum cleaner transitions from the third state to the fourth state. When the state of the vacuum cleaner is the fourth state, the microcomputer 21 performs control to reduce the output of the electric blower 9 for the purpose of reducing power consumption and preventing deterioration of the battery 8. For example, the output of the electric blower 9 is about 10% of the output when the state of the vacuum cleaner is in the third state. Furthermore, the microcomputer 21 cuts off the supply of power to the suction attachment 3. At this time, the output to the electric blower 9 is not completely cut off. For this reason, the user is notified that the power of the vacuum cleaner is on.

  Thereafter, the process proceeds to step S27. In step S27, the microcomputer 21 determines whether or not a predetermined time has elapsed.

  If the predetermined time set in step S27 has not elapsed, the process proceeds to step S28. In step S <b> 28, the microcomputer 21 determines whether the moving speed based on the output from the acceleration sensor 18 is equal to or higher than the threshold value B.

  If the moving speed is less than the threshold value B in step S28, the process returns to step S27. If the moving speed is greater than or equal to the threshold value B in step S28, the microcomputer 21 determines that cleaning has been resumed. In this case, the process returns to step S24.

  If the predetermined time set in advance in step S27 has elapsed, the microcomputer 21 determines that cleaning is not resumed. In this case, the process returns to step S21.

  If the suction attachment 3 connected in step S23 is the “futon” suction attachment 3, the process proceeds to step S29.

  In step S29, the state of the vacuum cleaner transitions from the second state to the fifth state after a predetermined time has elapsed. When the state of the vacuum cleaner is in the fifth state, the electric blower 9 and the suction attachment 3 are supplied with electric power. At this time, the output of the electric blower 9 is about 80% of the output when the vacuum cleaner is in the second state. Thereafter, the process proceeds to step S30.

  In step S <b> 30, the microcomputer 21 determines whether the moving speed based on the output from the acceleration sensor 18 is equal to or less than the threshold value C. If the moving speed is greater than the threshold value C in step S30, step S30 is repeated. If the moving speed is equal to or lower than the threshold value C in step S30, the process proceeds to step S31.

  In step S31, the state of the vacuum cleaner transitions from the fifth state to the sixth state. When the state of the vacuum cleaner is the sixth state, the microcomputer 21 performs control to reduce the output of the electric blower 9 for the purpose of reducing power consumption and preventing the battery 8 from being deteriorated. For example, the output of the electric blower 9 is about 10% of the output when the state of the vacuum cleaner is in the fifth state. Furthermore, the microcomputer 21 cuts off the supply of power to the suction attachment 3. At this time, the output to the electric blower 9 is not completely cut off. For this reason, the user is notified that the power of the vacuum cleaner is on.

  Thereafter, the process proceeds to step S32. In step S32, the microcomputer 21 determines whether or not a predetermined time has elapsed.

  If the predetermined time set in advance in step S32 has not elapsed, the process proceeds to step S33. In step S <b> 33, the microcomputer 21 determines whether the moving speed based on the output from the acceleration sensor 18 is equal to or higher than the threshold value D.

  If the moving speed is less than the threshold value D in step S33, the process returns to step S32. If the moving speed is greater than or equal to the threshold value D in step S33, the microcomputer 21 determines that cleaning has been resumed. In this case, the process returns to step S29.

  If the predetermined time set in advance in step S32 has elapsed, the microcomputer 21 determines that cleaning is not resumed. In this case, the process returns to step S21.

  According to the first embodiment described above, the electric blower 9 is controlled based on the determination result of the type of the suction attachment 3 and the detection result of the motion detector 22. For this reason, the electric blower 9 can be controlled according to the usage of cleaning without the operation of setting the type of attachment at the hand operating unit 10.

  More specifically, the electric blower 9 is controlled based on the determination result of the type of the suction attachment 3 and the moving speed based on the output from the acceleration sensor 18. For this reason, the electric blower 9 can be controlled more appropriately according to the use of cleaning.

  Further, the threshold for determining the state of the vacuum cleaner is changed according to the type of the suction attachment 3. For example, the threshold for determining “fast”, “normal”, “slow”, and “stop” in the moving speed for each attachment is changed according to the type of the attachment 3 for suction. For example, in the movement speed for each attachment, “fast”, “normal”, “slow”, and “stop” are determined based on acceleration during movement as shown in Table 1.

  For this reason, it is possible to suppress erroneous determination by the microcomputer 21 if the cleaning is not performed while the cleaning is performed by the electric vacuum cleaner. For example, the cleaning operation for the futon is slower than the cleaning operation for the floor surface. During the cleaning operation on the floor surface, the vibration of the electric blower 9 is transmitted to the acceleration sensor 18 through the floor surface. Even in this case, erroneous determination by the microcomputer 21 can be suppressed. At this time, an operation button for setting the usage of cleaning is unnecessary. For this reason, not only can the number of operation buttons and wiring be reduced, but also an operation for setting the purpose of cleaning becomes unnecessary. As a result, the usability of the electric vacuum cleaner can be improved.

  The electric blower 9 may be controlled based on the determination result of the type of the attachment 3 for suction in a vacuum cleaner having a paper collection type dust collection method. Further, in a stand-type vacuum cleaner to which power is supplied from a commercial power source, the electric blower 9 may be controlled based on the determination result of the type of the suction attachment 3. Furthermore, in the vacuum cleaner in which the extension pipe 2 is a bellows type hose, the electric blower 9 may be controlled based on the determination result of the type of the suction attachment 3. Also in these cases, the electric blower 9 can be controlled according to the purpose of cleaning.

  Further, the motion detector 22 may be provided inside the hand operation unit 10. At this time, the electric blower 9 may be controlled based on the determination result of the type of the attachment 3 for suction and the moving speed based on the output from the acceleration sensor 18. Also in this case, the electric blower 9 can be controlled more appropriately according to the purpose of cleaning.

  Moreover, you may determine a some use condition as a use condition of a vacuum cleaner. For example, the state of the vacuum cleaner may be changed to the state L when the output of the acceleration sensor 18 during the preset period R is I or more. For example, the state of the vacuum cleaner may be changed to the state M when the output of the acceleration sensor 18 during the preset period R is greater than or equal to J and less than I. For example, when the output of the acceleration sensor 18 during a preset period R is less than J, the state of the vacuum cleaner may be changed to the state N.

  Further, the current flowing through the suction attachment 3 may be detected by a current transformer or a current sensor using a Hall element. Further, the types of two or more suction attachments 3 may be determined according to the resistance value of the attachment determination resistor.

  Moreover, in the hand operation part 10, you may provide the switch which switches the output of the motor of the electric blower 9 in a part of switch part 10a. For example, a switch that switches the output of the motor of the electric blower 9 from one of “strong” and “weak” to the other may be provided in a part of the switch unit 10a. For example, when the switch is operated, the output of the motor of the electric blower 9 may be switched as shown in Table 2.
