The control means 37 controls the phase of the operation of the electric blower 18 through the triac Tr1 as an electric blower control element and is arranged in the exhaust air passage of the electric blower 18, . Also, the control means 37 is supplied with power from the commercial AC power source e via a power cord, not shown, for example.

The power supply unit 38 is configured to supply power from the commercial AC power supply e when the power cord is electrically connected to the commercial AC power supply e, that is, when the power supply (voltage) And is a constant voltage source that generates a predetermined constant voltage, for example, a voltage of 5 V by electric power supply.

The amplifying unit 39 is electrically connected to the control unit 37 through the pulse shaping unit 40.

3, the handle operating portion 27 is formed into a substantially cylindrical shape by a hard synthetic resin or the like, as compared with the hose body 25, and has a handle A protruding portion 41 is formed. A plurality of setting buttons 42 as setting means for setting the operation of the electric blower 18 and the like to the control means 37 (Fig. 1) are disposed in the grip portion 41. Fig. These setting buttons 42 are electrically connected to the control means 37 (Fig. 1) or the like in the cleaner main body 12 through the wiring in the hose main body 25. An operation detecting means 45 for detecting the operation of the handle operating portion 27 is disposed inside the grip portion 41. [ The operation detecting means 45 detects whether or not the grip operating portion 27 is operating (stopped), in other words, when the user operates the grip operating portion 27 Or the like) is used. The operation detecting means 45 is electrically connected to the control means 37 as shown in Fig.

The bottom brush 23 shown in Fig. 3 is configured to be able to constitute a part (upstream end) of the air passage W and is provided with a connecting pipe 22 having one end side communicatingly connected to the leading end side (upstream end side) And a transversely elongated case body 48 rotatably connected to the other end side of the connection pipe 47 in the up-and-down direction or in the circumferential direction so as to travel on the surface to be cleaned. A suction port communicating with the other end side of the connection pipe 47 is formed in a lower portion opposed to the bottom surface of the case body 48.

Next, the operation of the first embodiment will be described with reference to the matrix shown in Fig. 4 and the flowchart shown in Fig.

When the user connects (plugs in) the power cord to a wall outlet or the like in a state where the dust collecting section is installed in the cleaner main body 12, power is supplied from the commercial AC power source e to the power source section 38 Voltage) is supplied (applied).

The control means 37 waits for the operation input of the setting button 42 so that the electric blower 18 driving or driving the electric blower 18 in the operation mode set by the operation of the setting button 42 ). Hereinafter, the operation of each unit in the case where the electric blower 18 is driven in the automatic mode, that is, the mode in which the input is automatically controlled by the control unit 37, will be described.

The user moves the floor brush 23 back and forth on the surface to be cleaned through the gripper 41 after the electric blower 18 is driven and the air is blown by the negative pressure of the electric blower 18 driving the dust on the surface to be cleaned W) and is collected in the dust collecting part.

In this cleaning state, the control means 37 amplifies the output signal outputted from the optical sensor 33, for example, by the amplifying unit 39, and outputs the pulse-shaped input The amount of dust passing through the air passage W is monitored by a signal. In other words, the electric vacuum cleaner 11 detects the dust amount by the optical sensor 33 (step 1).

That is, when dust passes through the air passage W, dust is blocked by the light emitted from the light emitting element 35a of the light emitting portion 35, so that the amount of light received by the light receiving element 36a of the light receiving portion 36 is reduced , It is possible to detect that the dust passes through the air passage (W) by the light sensor (33). The amount of light received by the light receiving element 36a of the light receiving section 36 decreases as the amount of dust passing through the air passage W increases so that the output signal from the optical sensor 33 is amplified by the amplifying section 39 The input signal to be inputted to the control means 37 is relatively reduced by the pulse shaping device 40 so that the control means 37 can control the flow rate of the air passing through the air passage W ) Excess amount of dust can be judged by the magnitude of the input signal.

Then, the control means 37 judges whether or not the amount of dust detected by the optical sensor 33 is equal to or larger than a preset predetermined amount, for example, by comparing the input signal with a predetermined threshold value The control means 37 determines whether or not the handle operating portion 27 is operated by the operation detecting means 45 (Step 3 (Step 3)), ).

When the control means 37 determines that the handle operating portion 27 is not operating (the handle operating portion 27 is stopped) in Step 3, for example, when the user grasps the handle operating portion 27 , It is assumed that the air cleaner 11 is not cleaned as usual and the cleaned state is that the air cleaner 11 (electric blower 18) is driven and the air passage forming body 13 is left , The control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to a predetermined first minimum value for the electric blower which is the smallest minimum value and sets the electric blower 18 And operates with a predetermined first electric blower input (power 1) which is the lowest input (step 4).

When the control means 37 determines that the handle operating portion 27 is operating (the handle operating portion 27 is not stopped) in Step 3, for example, when the user operates the floor brush The control means 37 assumes a state in which the amount of dust on the surface to be cleaned is small and the control means 37 controls the operation of the input of the electric blower 18 set by the triac Tr1 The electric blower 18 is operated with a predetermined second electric blower input (power 2) larger than the first electric blower input, with the phase angle being a second value for a predetermined electric blower larger than the first value for the electric blower Step 5).

On the other hand, when it is determined in step 2 that the amount of dust detected by the optical sensor 33 is equal to or greater than the predetermined amount, the control unit 37 determines whether or not the handle operating unit 27 is operated by the operation detecting unit 45 (Step 6).

When the control means 37 determines that the handle operating section 27 is not operating (the handle operating section 27 is stopped) in this step 6, for example, when dust is partially stored on the wall or the like The controller 37 assumes that the phase angle of the input of the electric blower 18 set by the triac Tr1 is equal to the phase angle of the input of the third electric blower 3 The electric blower 18 is operated with a predetermined third electric blower input (power 3) larger than the second electric blower input (step 7).

When the control means 37 determines that the handle operating portion 27 is operating (the handle operating portion 27 is not stopped) in Step 6, the amount of dust on the surface to be cleaned is large, And the control means 37 determines whether or not the phase of the input of the motor-driven blower 18 set by the triac Tr1 The electric blower 18 is operated with a predetermined fourth electric blower input (power 4) larger than the third input by setting the angle as a fourth value for a predetermined electric blower larger than the third value for the electric blower (step 8) .

That is, a cleaning state is assumed on the basis of the amount of dust detected by the optical sensor 33 and the operation state of the handle operating section 27 detected by the operation detecting means 45. In accordance with the assumed cleaning state, The control unit 37 controls the driving (input) of the electric blower 18 so that the cleaning state of the user can be accurately determined on the basis of the two pieces of information, that is, information from the optical sensor 33 and information from the operation detecting unit 45 And can be cleaned with electric power suitable for the cleaning state.

Next, a second embodiment will be described with reference to Fig. 6 or Fig. The same components and operations as those of the first embodiment are denoted by the same reference numerals, and a description thereof will be omitted.

In the second embodiment, in the first embodiment, the bottom brush 23 is provided with a rotary brush 51 as a rotary cleaning body.

7, the bottom brush 23 is rotatably provided with a rotary brush 51 at a horizontally elongated suction opening formed in a lower surface opposed to the surface to be cleaned of the case body 48. As shown in Fig. The rotary brush 51 is connected to an electric motor 52 housed in a case 48 via a transmission means 53 such as a belt and is rotationally driven by the electric motor 52. [

The rotary brush 51 scrapes dust that has entered or adhered to the surface to be cleaned by rotation. The rotary brush 51 may have any structure, but it is preferable to include a cleaning member such as a fur brush or a blade.

As shown in Fig. 6, the electric motor 52 is phase-controlled by the control means 37 through the triac Tr2 as a motor control element. It is assumed that the electric motor 52 is turned on and off simultaneously with on-off of the electric vacuum cleaner 11 (electric blower 18) (corresponding to on-off). These control means 37 and the electric motor 52 (triacol Tr2) are electrically connected to each other by wiring (not shown) through the inside of the air passage forming body 13. [

Next, the operation of the second embodiment will be described with reference to the matrix shown in Fig. 8 and the flowchart shown in Fig.

When the high control means 37 determines that the handle operating portion 27 is not operating (the handle operating portion 27 is stopped) in Step 3 of the first embodiment described above, for example, The air cleaner 11 (electric blower 18) is driven while the air cleaner 11 is not normally cleaned, for example, State and the like and the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to the first value for the electric blower so that the electric blower 18 (1), and the phase angle of the input of the motor (52) set by the triac (Tr2) is set to a predetermined first minimum value, which is the smallest minimum value, (52) to a predetermined first motor input which is the lowest input Thereby rotating the rotary brush 51 at a predetermined first rotation speed (rotation speed 1) which is the minimum rotation speed (step 11).

When the control means 37 determines that the handle operating portion 27 is operating (the handle operating portion 27 is not stopped) in Step 3, for example, when the user operates the floor brush The control means 37 assumes a state in which the amount of dust on the surface to be cleaned is small and the control means 37 controls the operation of the input of the electric blower 18 set by the triac Tr1 The electric blower 18 is operated as the second electric blower input (power 2) while the phase angle is set to the second value for the electric blower and the input of the electric motor 52 set by the triac Tr2 And the motor 52 is operated as a predetermined second motor input which is larger than the first motor input so that the rotary brush 51 is rotated by the first motor input to the first A predetermined second number of revolutions (times Be rotated to 2) (step 12).

When the control means 37 determines that the handle operating portion 27 is not operating (the handle operating portion 27 is stopped) in Step 6, it is judged by the control means 37 that, for example, And the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the third value for the electric blower, The phase angle of the input of the electric motor 52 set by the triac Tr2 is set to a predetermined electric motor which is larger than the second value for the electric motor by operating the blower 18 with the third electric blower input (power 3) By operating the motor 52 as a third motor input that is larger than the second motor input, the rotary brush 51 is rotated at a predetermined third rotation speed (rotation speed 3 (Step 13).

When the control means 37 determines that the handle operating portion 27 is operating (the handle operating portion 27 is not stopped) in Step 6, the amount of dust on the surface to be cleaned is large, The control means 37 assumes a cleaning state in which the floor brush 23 is moved back and forth as usual in order to perform cleaning and the like and the control means 37 controls the input of the electric blower 18 set by the triac Tr1 The phase angle is set to a fourth value for the electric blower so that the electric blower 18 is operated with the fourth electric blower input (power 4) and the input of the electric motor 52 set by the triac Tr2 The phase angle of the electric motor 52 is set to a predetermined fourth electric motor value larger than the third value for the electric motor and the electric motor 52 is operated as the predetermined fourth electric motor input larger than the third electric motor input, A predetermined fourth rotation number (" It rotates to transfer 4) (step 14).

In this way, the control means 37 assumes the cleaning state based on the amount of dust detected by the optical sensor 33 and the operation of the handle operating section 27 detected by the operation detecting means 45, Not only the electric blower 18 but also the electric motor 52 (the rotary brush 51) are cleaned by controlling the drive of the electric blower 18 and the electric motor 52 (the rotary brush 51) It is possible to perform cleaning with an electric power suited to the cleaning state, thereby saving energy, and dust on the surface to be cleaned can be scraped off by the electric motor 52 (rotating brush 51) , The cleaning performance can be further improved.

Next, a third embodiment will be described with reference to Figs. 10 to 13. Fig. The same components and operations as those of the above-described embodiments are denoted by the same reference numerals, and a description thereof will be omitted.

The third embodiment differs from the first embodiment in that the floor brush 23 is provided with the ground detecting means 55 for detecting the grounding state of the floor brush 23.

As shown in Fig. 11, the ground detecting means 55 is movably provided in an opening 56 formed in a lower surface opposed to the surface to be cleaned of the case body 48. As shown in Fig. The ground detecting means 55 includes a wheel 57 as a ground portion and a changeover switch which is turned on and off by grounding and non-grounding of the wheel 57, The support member 59 is rotatably supported by the support member 59 and is rotatably supported by the case member 48. When the floor brush 23 is brought into contact with the surface to be cleaned (grounded), the wheel 57 is brought into contact with the surface to be cleaned so that the wheel 57 rotates together with the support member 59 and is housed in the opening 56, The grounding of the floor brush 23 is detected by turning the switch 59 on the rotating supporting member 59 and the supporting brush 59 is moved away from the surface to be cleaned The wheel 57 protrudes from the opening 56 so that the support member 59 is separated from the changeover switch and the changeover switch is turned off so that the grounded portion of the floor brush 23 is detected.

10, the ground detecting means 55 is electrically connected to the control means 37 and is connected to the control means 37 via the on / off switch of the ground detecting means 55. [ So as to recognize the grounding / non-grounding of the floor brush 23. The ground detecting means 55 and the control means 37 are electrically connected to each other by wiring (not shown) passing through the inside of the air passage forming body 13. Thus, for example, when the floor brush 23 is removed from the extension pipe 22, or when the extension pipe 22 and the floor brush 23 are removed from the handle control portion 27 and another suction member such as an elongated nozzle The electrical connection between the ground detecting means 55 and the control means 37 is cut off so that the control means 37 determines that the floor brush 23 is not grounded . That is, the ground detecting means 55 detects the ground / non-grounded state of the bottom brush 23, thereby determining whether the floor brush 23 is used, whether the floor brush 23 is removed and another suction ball is used, And has a function of connection detecting means. It is assumed here that the grounding / non-grounding detected by the grounding detecting means 55 by the control means 37 includes the connection / non-connection speed of the floor brush 23.

Next, the operation of the third embodiment will be described with reference to the matrix shown in Fig. 12 and the flowchart shown in Fig.

First, in step 3, when the control means 37 determines that the handle operating section 27 does not operate (the handle operating section 27 is stopped), the control means 37 controls the ground detecting means It is determined whether or not the floor brush 23 is grounded (step 21).

When it is determined in step 21 that the floor brush 23 is not grounded, the control means 37 controls the floor brush 23 (and the extension pipe 22 For example, a state in which the user does not grip the handle control portion 27 and does not perform the usual cleaning, for example, the electric vacuum cleaner 11 The controller 37 assumes that the electric blower 18 set by the triac Tr1 is in a state of being kept in the state where the air passage forming body 13 is left while driving the electric blower 18 The electric fan 18 is operated with the first electric blower input (power 1) (step 22), with the phase angle of the input of the electric blower 18 being the first value for the electric blower.

When it is determined in step 21 that the floor brush 23 is grounded, the control means 37 controls the amount of dust on the surface to be cleaned, for example, The controller 37 assumes that the phase angle of the input of the motor-driven blower 18 set by the triac Tr1 is equal to or greater than the phase angle of the input of the electric blower 18 set by the triac Tr1, And operates the electric blower 18 with the second electric blower input (power 2) as a second value (step 23).

When the control means 37 determines that the knob control section 27 is operating (the knob control section 27 is not stopped) in Step 3, the control means 37, similarly to Step 21, The ground detecting means 55 determines whether or not the floor brush 23 is grounded (step 24).

When it is determined in step 24 that the floor brush 23 is not grounded, the control means 37 determines that the dust on the surface to be cleaned is small, for example, the floor brush 23 The control means 37 assumes a state of cleaning the electric blower 18 to be set by the triac Tr1, and the control means 37 assumes a state of cleaning such as cleaning by connecting another suctioning body such as a long nozzle, The phase angle of the input is set to a second value for the electric blower so that the electric blower 18 is operated with the second electric blower input (power 2) (step 25).

When the floor brush 23 is judged to be grounded in step 24, the control means 37 grounds the bottom brush 23 on the surface to be cleaned, for example, although the amount of dust on the surface to be cleaned is small, And the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to the third value for the electric blower 18 so that the electric blower 18 Is operated with the third electric blower input (power 3) (step 26).

On the other hand, when the control means 37 determines that the handle operating portion 27 is not operating (the handle operating portion 27 is stopped) in Step 6, the control means 37 Is judged by the ground detecting means 55 whether or not the floor brush 23 is grounded (step 27).

When it is determined in step 27 that the floor brush 23 is not grounded, the control means 37 controls the floor brush 23, for example, in a place where the gap between the furniture and the wall is narrow, ) Is removed and other suctioning spheres such as elongated nozzles are connected to suction the dust stored by the suction air volume. Therefore, it is assumed that the cleaning means is a cleaning state for stopping and cleaning the suctioning body for a predetermined time, 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to the third value for the electric blower and sets the electric blower 18 to the third electric blower input (power 3) (Step 28).

If it is determined in step 27 that the floor brush 23 is grounded, the control means 37 controls the floor brush 23 to clean the corner, wall, or the like of the surface to be cleaned, for example, And the control means 37 assumes the phase angle of the input of the electric blower 18 set by the triac Tr1 to be the fourth value for the electric blower and sets the electric blower 18 to the fourth And operates with an electric blower input (power 4) (step 29).

When the high control means 37 determines that the handle operating portion 27 is operating (the handle operating portion 27 is not stopped) in Step 6, as in Steps 21, 24, and 27, The controller 37 judges whether or not the floor brush 23 is grounded by the ground detecting means 55 (step 30).

When it is determined that the floor brush 23 is not grounded in this step 30, the control means 37 controls the floor surface to be cleaned, for example, with respect to a wide range of the surface to be cleaned, such as a shelf with a large amount of dust, And the control means 37 assumes a state of cleaning which is cleaned by using another suctioning means such as a household brush or the like after removing the electric blower (and the extension pipe 22) 18) is set to the fourth value for the electric blower, and the electric blower 18 is operated with the fourth electric blower input (power 4) (step 31).

When it is determined in step 30 that the floor brush 23 is grounded, the control means 37 controls the floor brush 23 so that the amount of dust on the surface to be cleaned is large and the user grounds the floor brush 23, The controller 37 assumes the phase angle of the input of the motor-driven blower 18 set by the triac Tr1 to be the same as that of the motor- The electric blower 18 is operated with a predetermined fifth electric blower input (power 5), which is the maximum input larger than the fourth electric blower input (Step 5), as a fifth value for a predetermined electric blower, 32).

As described above, the ground state detecting device 55 detects the ground state (connected state) of the suction brush of the bottom brush 23 or the elongated nozzle, and the control device 37 detects the ground state A cleaning state is assumed on the basis of the detected dust amount, the operation of the handle operating portion 27 detected by the operation detecting means 45, and the ground state (connection state) of the suction ball detected by the ground detecting means 55, The cleaning state of the user is controlled by the information from the optical sensor 33 and the information from the operation detecting means 45 and the ground detecting means 55 by controlling the drive of the electric blower 18 in response to the assumed cleaning state, It is possible to make a more accurate assumption based on the three kinds of information, and it is possible to clean with appropriate electric power by the cleaning state, thereby further saving energy. That is, for example, when the floor brush 23 is grounded (connected), the floor brush 23 is connected to the input (not connected) of the electric blower 18 It is necessary to use a floor brush 23 that requires power, for example, to clean the surface to be cleaned such as a bottom surface, and to clean the surface to be cleaned when the floor area is narrower than the floor brush 23, The control means 37 can identify when cleaning is performed using a suction nozzle such as an elongated nozzle or the like in which the power of the electric blower 18 can be small and can be properly set by the input of the electric blower 18. [

Although the bottom brush 23 may be provided with the rotary brush 51 and the electric motor 52 of the second embodiment described above in the first and third embodiments, (The rotary brush 51) is controlled independently of the electric blower 18.

Next, a fourth embodiment will be described with reference to Figs. 14 to 16. Fig. The same components and operations as those of the above-described embodiments are denoted by the same reference numerals, and a description thereof will be omitted.

In the fourth embodiment, as shown in Fig. 14, the second embodiment has the ground detecting means 55 of the third embodiment.

15 and the flowchart shown in Fig. 16, when it is judged at step 21 that the floor brush 23 is not grounded, the amount of dust on the surface to be cleaned is small, for example, The control means 37 assumes that the air conditioner 13 has been left in a state in which the user has dropped the floor brush 23 against the surface to be cleaned and the control means 37 determines that the electric blower 12 is set by the triac Tr1, The phase angle of the input of the electric blower 18 is set to the first value for the electric blower so that the electric blower 18 is operated with the first electric blower input (power 1) and is set by the triac Tr2 The phase angle of the input of the electric motor 52 is set to 0, and the electric motor 52, that is, the rotary brush 51 is stopped (step 41).

When it is determined in step 21 that the floor brush 23 is grounded, the control means 37, for example, grounds the floor brush 23 to the surface to be cleaned, presses the floor brush 23 with a small amount of dust, State and the like and the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the second value for the electric blower, (2), the phase angle of the input of the motor (52) set by the triac (Tr2) is set to a second value for the electric motor, and the electric motor (52) By operating the motor as an input, the rotary brush 51 is rotated at the second rotation speed (rotation speed 2) (step 42).

Likewise, when it is determined in step 24 that the floor brush 23 is not grounded, the control means 37 determines that the dust on the surface to be cleaned is small, for example, but the floor brush 23 The controller 37 assumes a clean state in which the suction fan 22 is removed and is cleaned by using other suction cups such as elongated nozzles or the like and the control means 37 controls the input of the electric blower 18 set by the triac Tr1 The electric blower 18 is operated with the second electric blower input (power 2) and the phase angle of the electric motor 52 set by the triac Tr2 is set to a second value for the electric blower The phase angle of the input is set to 0, and the electric motor 52 (i.e., the rotary brush 51) is stopped (step 43).

When the floor brush 23 is judged to be grounded in step 24, the control means 37 grounds the bottom brush 23 on the surface to be cleaned, for example, although the amount of dust on the surface to be cleaned is small, And the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to the third value for the electric blower 18 so that the electric blower 18 And the phase angle of the input of the electric motor 52 set by the triac Tr2 is set to the third value for the electric motor so that the electric motor 52 is operated as the third electric blower input By operating the third motor input, the rotary brush 51 is rotated at the third rotation speed (the number of revolutions 3) (step 44).

When it is determined in step 27 that the floor brush 23 is not grounded, the control means 37 controls the floor brush 23, for example, in a place where the gap between the furniture and the wall is narrow, It is assumed that it is a cleaning state in which the suctioning ball is stopped and cleaned for a predetermined period of time for suctioning the dust stored by the suction air volume, The electric blower 18 is operated with the third electric blower input (power 3) by setting the phase angle of the input of the electric blower 18 set by the triac Tr1 as the third value for the electric blower, The motor 52 or the rotary brush 51 is stopped (step 45) by setting the phase angle of the input of the electric motor 52 set by the triac Tr2 to zero.

When it is determined in step 27 that the floor brush 23 is grounded, the control means 37 controls the floor brush 23 to clean, for example, the corner of the surface to be cleaned, And the control means 37 assumes the phase angle of the input of the electric blower 18 set by the triac Tr1 to be the fourth value for the electric blower and sets the electric blower 18 to the fourth (4), the phase angle of the input of the motor (52) set by the triac (Tr2) is set to the fourth value for the electric motor, and the electric motor (52) The rotation brush 51 is rotated at the fourth rotation speed (rotation speed 4) (step 46).

If it is determined in step 30 that the floor brush 23 is not grounded, the control means 37 controls the floor brush 23, for example, on a wide range of surfaces to be cleaned, such as on a lathe having a large amount of dust, The controller 37 assumes that the electric blower 18 set by the triac Tr1 is in the cleaning state or the like which is cleaned by using the suction brushes of the household brush or the like after removing the electric blower (and the extension pipe 22) (4) for the motor-driven blower (18) is set to a fourth value for the motor-driven blower, the electric motor (52) set by the triac (Tr2) , The motor 52 (i.e., the rotary brush 51) is stopped (step 47).

When it is determined in step 30 that the floor brush 23 is grounded, the control means 37 controls the floor brush 23 so that the amount of dust on the surface to be cleaned is large and the user grounds the floor brush 23, The control means 37 assumes the phase angle of the input of the motor-driven blower 18 set by the triac Tr1 to be the same as that of the motor- (5), and sets the phase angle of the input of the electric motor (52) set by the triac (Tr2) to the motor-driven blower 4, the motor 52 is operated as a predetermined fifth motor input which is a maximum input larger than the fourth motor input, whereby the rotary brush 51 is rotated to the fourth rotation The maximum number of revolutions greater than the number To define a fifth rotational rotated by (revolutions 5) (step 48).

As described above, the ground state detecting device 55 detects the ground state (connected state) of the suction brush of the bottom brush 23 or the elongated nozzle, and the control device 37 detects the ground state The electric blower 18 and the electric blower 18 are controlled in accordance with the detected dust amount, the operation of the handle operating portion 27 detected by the operation detecting means 45 and the ground state (connected state) of the suction ball detected by the ground detecting means 55 By controlling the driving of the electric motor 52 (the rotary brush 51), the cleaning state of the user can be assumed to be more precise, and the cleaning can be performed with a suitable electric power, thereby further saving energy. That is, for example, when the floor brush 23 is grounded (connected), the floor brush 23 is connected to the input (not connected) of the electric blower 18 It is possible to use a floor brush 23 that requires power, for example, to clean a surface to be cleaned such as a floor surface, and to use a thin, long nozzle The control means 37 can identify the time of cleaning using the suction ball, and the like, so that it is possible to appropriately set by the input of the electric blower 18. [ In addition, when the ground detecting means 55 detects the non-grounding (non-connection) of the bottom brush 23, the electric motor 52 (the rotating brush 51) is stopped so that unnecessary power consumption is suppressed, Energy saving becomes possible.

Next, a fifth embodiment will be described with reference to Figs. 17 and 18. Fig. The same components and operations as those of the above-described embodiments are denoted by the same reference numerals, and a description thereof will be omitted.

The fifth embodiment basically has the same configuration as that of the fourth embodiment, but the control by the control unit 37 is different from that of the fourth embodiment.

Specifically, in the fifth embodiment, each of the following steps 51 to 54 is performed in place of the respective controls of the steps 45 to 48 of the fourth embodiment.

17, the controller 37 determines that the floor brush 23 is not grounded in step 27. For example, the controller 37 determines that the floor brush 23 is not grounded, For example, the bottom brush 23 is removed and another suctioning body such as a long nozzle is connected to suck the dust stored by the suction air volume. Therefore, And the control means 37 assumes the phase angle of the input of the electric blower 18 set by the triac Tr1 as the fifth value for the electric blower, The phase angle of the input of the motor 52 set by the triac Tr2 is made to be 0 and the electric motor 52 is rotated by the rotation of the electric motor 52 When the brush 51 is rotated Thereby (step 51).

When the bottom brush 23 is determined to be grounded in step 27, the control means 37 controls the position of the bottom brush 23 with respect to the corner, wall, or the like of the dust- And the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to the fifth value for the electric blower , The electric blower 18 is operated with the fifth electric blower input (power 5), and the phase angle of the input of the electric motor 52 set by the triac Tr2 is set to the fifth value for the electric motor , And rotates the rotary brush 51 at the fifth rotation speed (rotation speed 5) by operating the electric motor 52 as the fifth electric motor input (step 52).

If it is determined in step 30 that the floor brush 23 is not grounded, the control means 37 controls the floor brush 23, for example, on a wide range of surfaces to be cleaned, such as on a lathe having a large amount of dust, The controller 37 assumes that the electric blower 18 set by the triac Tr1 is in the cleaning state or the like which is cleaned by using the suction brushes of the household brush or the like after removing the electric blower (and the extension pipe 22) (3) for setting the phase angle of the input to the electric blower (18) to the third electric blower input (power 3) while setting the phase angle of the input of the electric motor The phase angle of the input of the electric motor 52 (i.e., the rotary brush 51) is made zero (step 53).

When it is determined in step 30 that the floor brush 23 is grounded, the control means 37 determines that the amount of dust on the surface to be cleaned is large and the user grounds the floor brush 23, The control means 37 assumes the phase angle of the input of the motor-driven blower 18 set by the triac Tr1 to be the same as that of the motor- (4), and sets the phase angle of the input of the motor (52) set by the triac (Tr2) to the fourth motor-blower input (power 4) The rotation brush 51 is rotated at the fourth rotation speed (rotation speed 4) by operating the electric motor 52 as the fourth electric motor input as a fourth value (step 54).

When the amount of dust detected by the optical sensor 33 is equal to or greater than the predetermined amount and the operation detecting unit 45 detects that the handle operating unit 27 is not operating, It is assumed that the control means 37 is a cleaning state in which the floor brush 23 or a suction nozzle such as a slender nozzle is used to intensively clean the position of a corner or a wall of the control panel 37 At least the input of the electric blower 18 is relatively increased, more specifically, driven by the maximum input set in advance according to the type of the electric vacuum cleaner 11 or the like, thereby effectively cleaning the dust in accordance with the cleaning state of the user So that the usability is improved.

It is also possible to detect that the amount of dust detected by the optical sensor 33 is equal to or greater than a predetermined amount and that the operation detecting unit 45 does not operate the handle operating unit 27 and that the ground detecting unit 55 When the ground brush 23 is detected to be grounded, for example, the user may ground the bottom brush 23 on the surface to be cleaned, with respect to the corner of the surface to be cleaned, The control means 37 assumes that the electric blower 18 and the electric motor 52 are in a state that the input of the electric motor 52 is relatively increased, It is possible to clean the dust more effectively in accordance with the cleaning state of the user by driving each of them with the set maximum input, and the usability is further improved.

In other words, when only the operation detecting means 45 is provided, there is a possibility that the control means 37 may lower the input when detecting that the handle operating portion 27 is not operating. However, in this embodiment, 33 and the operation detecting means 45 are provided so that the user can use the suction brush of the floor brush 23 or the suction nozzle such as the elongated nozzle for the position of the corner of the surface to be cleaned, It is possible to cope with a cleaning state that is being cleaned. Therefore, the electric blower 18 and / or the electric motor 52 (the rotary brush 51) can be driven with a suitable electric power by the cleaning state, and the cleaning can be reliably performed. In other words, by including both the optical sensor 33 and the operation detecting means 45, the cleaning state can be complementarily detected, and the cleaning can be effectively performed.

Next, a sixth embodiment will be described with reference to Figs. 19 and 20. Fig. The same components and operations as those of the above-described embodiments are denoted by the same reference numerals, and a description thereof will be omitted.

The sixth embodiment basically has the same configuration as that of the fourth embodiment, but control by the control means 37 is different from that of the fourth embodiment.

Specifically, the sixth embodiment controls the following steps 61 to 66 in place of the respective controls of the steps 43 to 48 of the fourth embodiment.

19 and the flow chart shown in Fig. 20, if it is determined in step 24 that the floor brush 23 is not grounded, it is determined that the ground brush 23 is not grounded, for example, It is presumed that a cleaning state requiring a relatively small amount of dust but a strong power, for example, when dust is removed, for example, the floor brush 23 is removed and another suctioning body such as a long nozzle is connected and cleaned, 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to the fifth value for the electric blower so that the electric blower 18 is switched to the fifth electric blower input (power 4) The motor 52 and the rotary brush 51 are stopped (step 61), with the phase angle of the input of the motor 52 set by the triac Tr2 being zero.

When it is judged in step 24 that the floor brush 23 is grounded, the control means 37 controls the dust collecting means such as a thread bundle stuck on the surface to be cleaned, And the control means 37 assumes the phase angle of the input of the electric blower 18 set by the triac Tr1 as the fifth value for the electric blower, The phase angle of the input of the motor 52 set by the triac Tr2 is set to the fifth value for the motor while the blower 18 is operated by the fifth electric blower input (power 5) The rotation brush 51 is rotated at the fifth rotation speed (the number of revolutions 5) by operating the second motor 52 as the fifth electric motor input (step 62).

When it is determined in step 27 that the floor brush 23 is not grounded, the control means 37 controls the floor brush 23, for example, in a place where the gap between the furniture and the wall is narrow, It is assumed that it is a cleaning state in which the suctioning ball is stopped and cleaned for a predetermined period of time for suctioning the dust stored by the suction air volume, The electric blower 18 is operated by the second electric blower input (power 2) by setting the phase angle of the input of the electric blower 18 set by the triac Tr1 as the second value for the electric blower, The motor 52 or the rotary brush 51 is stopped (step 63) by setting the phase angle of the input of the motor 52 set by the triac Tr2 to zero.

When it is determined in step 27 that the floor brush 23 is grounded, the control means 37 controls the floor brush 23 to clean, for example, the corner of the surface to be cleaned, And the control means 37 assumes that the phase angle of the input of the electric blower 18 set by the triac Tr1 is the third value for the electric blower and the electric blower 18 is the third The phase angle of the input of the motor 52 set by the triac Tr2 is set to the third value for the electric motor and the electric motor 52 is operated by the third electric motor Thereby rotating the rotary brush 51 at the third rotation speed (rotation speed 3) (step 64).

If it is determined in step 30 that the floor brush 23 is not grounded, the control means 37 controls the floor brush 23, for example, on a wide range of surfaces to be cleaned, such as on a lathe having a large amount of dust, (Or extension pipe 22) is removed and a cleaning state in which the suction brush is cleaned by using another suction ball such as a furniture brush is assumed. The control means 37 controls the input of the electric blower 18 set by the triac Trl Of the electric motor 52 to be set by the triac Tr2 while operating the electric blower 18 with the third electric blower input (power 3) by setting the phase angle of the electric blower 18 as the third value for the electric blower, The phase angle of the input is set to 0 to stop the electric motor 52 (i.e., the rotary brush 51) (step 65).

When it is determined in step 30 that the floor brush 23 is grounded, the control means 37 controls the floor brush 23 so that the amount of dust on the surface to be cleaned is large and the user grounds the floor brush 23, The control means 37 assumes the phase angle of the input of the motor-driven blower 18 set by the triac Tr1 to be the same as that of the motor- (4), and sets the phase angle of the input of the motor (52) set by the triac (Tr2) to the fourth motor-blower input (power 4) The rotating brush 51 is rotated at the fourth rotational speed (rotational speed 4) by operating the electric motor 52 as the fourth electric motor input as a fourth value (step 66).

In this way, when the control means 37 detects that the amount of dust detected by the optical sensor 33 is equal to or smaller than the predetermined amount and the operation detecting means 45 operates the handle operating portion 27, The control means 37 determines that the dust is stuck to the surface to be cleaned by the user and the dust is hard to be removed using a suction brush such as the bottom brush 23 or the elongated nozzle, And this control means 37 drives at least the input of the electric blower 18 relatively to increase, specifically, the maximum input set in advance according to the type of the electric vacuum cleaner 11, It is possible to effectively clean the dust in accordance with the state, and the usability is improved.

It is also possible to detect that the amount of dust detected by the optical sensor 33 is equal to or less than a predetermined amount and that the operation detecting unit 45 detects that the handle operating unit 27 is operating, When the grounding of the brush 23 is detected, for example, dusts, such as thread bundles, which are difficult to peel off and stick to the surface to be cleaned, such as a rug, are cleaned using the floor brush 23 The control means 37 assumes the control means 37 and the input of the electric motor 52 with the electric blower 18 is also increased relative to the electric blower 18 and specifically set in advance according to the type of the electric vacuum cleaner 11 It is possible to clean the dust more effectively in accordance with the cleaning state of the user, and the usability is further improved.

That is, in the case where only the optical sensor 33 is provided, for example, when cleaning the surface to be cleaned such as a carpet having a thread bundle or the like attached thereto, dust is initially sucked and the amount of dust is judged to be more than a predetermined amount. The amount of dust may be judged to be less than a predetermined amount and the control means 37 may lower the input. However, in the present embodiment, both the optical sensor 33 and the operation detecting means 45 are provided , It is possible to cope with such a situation even when the dust such as the thread bundle which is stuck on the surface to be cleaned such as a carpet by the user is cleaned by using the suction brush of the floor brush 23 or the elongated nozzle have. Therefore, the electric blower 18 and / or the electric motor 52 (the rotary brush 51) can be driven with a suitable electric power by the cleaning state, and the cleaning can be reliably performed. In other words, by including both the optical sensor 33 and the operation detecting means 45, the cleaning state can be complementarily detected, and the cleaning can be effectively performed.

The control of step 51 of the fifth embodiment and the control of step 61 of the sixth embodiment can also be applied to the case of not having the ground detection unit 55 or the floor brush 23, respectively. That is, instead of the step (7) of the first embodiment or the step 13 of the second embodiment, the control of step 51 of the fifth embodiment may be performed, and the step 5 of the first embodiment or the step The input of the electric blower 18 may be increased by controlling the step 61 of the sixth embodiment instead of the step 12 of the second embodiment. The control of the fifth embodiment and the control of the sixth embodiment may be combined.

According to at least one embodiment described above, the control means 37 controls the amount of dust detected by the optical sensor 33 and the operation of the handle operating section 27 detected by the operation detecting means 45 At least the driving state of the electric blower 18 is controlled so that the cleaning state of the user can be estimated with high accuracy based on at least two kinds of information, that is, information from the optical sensor 33 and information from the operation detecting means 45 , It is possible to clean with an electric power suitable for the cleaning state, and it becomes possible to save energy.

In the above embodiments, the handle operating portion 27 is configured to grasp the air passage forming body 13, but it is also possible to use, for example, a so-called vacuum cleaner having a bottom brush 23 connected to the lower portion of the vacuum cleaner main body 12 In the case of an upright type electric vacuum cleaner or the like, the vacuum cleaner main body 12 may be used for gripping operation.

Although the input to each motor-driven blower and the input to each motor has been described using the common input in each of the embodiments, the input may be different for each of the embodiments if the magnitude relationship is maintained.

In addition, although some embodiments of the present invention have been described, these embodiments are presented as examples, and it is not intended to limit the scope of the present invention.
