In addition, the control means 37 phase-controls the operation of the electric blower 18 through, for example, the triac Tr1 as the electric blower control element, and is arranged in, for example, an exhaust air path of the electric blower 18. It is. In addition, this control means 37 is supplied with electric power from the commercial AC power supply e through the power cord which is not shown in figure, for example.

In addition, the power supply unit 38 is supplied 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) is applied (input), that is, plugged in. It is a constant voltage source which produces | generates predetermined | prescribed constant voltage, for example, 5V by electricity supply.

The amplifier 39 is electrically connected to the control means 37 via the pulse shaper 40.

In addition, as shown in FIG. 3, the handle operating portion 27 is formed in a substantially cylindrical shape with a synthetic resin harder than the hose main body 25, and is gripped by the user from the upstream end side to the downstream end side. The branch part 41 protrudes and is formed. In this holding | gripping part 41, the some setting button 42 as setting means for setting the operation of the electric blower 18 etc. to the control means 37 (FIG. 1) is arrange | positioned.

In addition, the bottom brush 23 shown in FIG. 3 can comprise a part (upstream end part) of the air path W, and the connection pipe which one end side communicates with the front end side (upstream end side) of the extension pipe 22 is connected. (47) and the horizontally long case body 48 connected to the other end side of this connection pipe 47 so that rotation is possible in an up-down direction, a circumferential direction, etc., and can run on the to-be-cleaned surface. Moreover, the suction port which communicates with the other end side of the connection pipe 47 is formed in the lower part which opposes 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. 5.

When the user connects (plugs in) the power cord to a wall outlet or the like in a state in which the dust collector is installed in the cleaner main body 12, the power source (e) Voltage) is supplied (applied).

The control means 37 waits for the operation input of the setting button 42, and drives or drives the electric blower 18 in the operation mode set by the user by the operation of the setting button 42. Stop). Hereinafter, the operation of each part in the case where the electric blower 18 is driven in an automatic mode, that is, a mode in which the input is automatically controlled by the control means 37 will be described.

After the electric blower 18 is driven, the user moves the bottom brush 23 back and forth on the surface to be cleaned through the holding part 41, and the air path is driven by the negative pressure of the electric blower 18 which has driven the dust on the surface to be cleaned. Inhale with air through W) and collect in the dust collecting part.

Moreover, in this cleaning state, the control means 37 amplifies the output signal output from the optical sensor 33 by the amplification part 39, and inputs it by pulse shaping by the pulse shaper 40, for example. The amount of dust passing through the air path W is monitored by the signal. In other words, the vacuum cleaner 11 detects the amount of dust by the optical sensor 33 (step 1).

That is, when dust passes through the air path W, since the dust blocks light emission from the light emitting element 35a of the light emitting portion 35, the amount of light received by the light receiving element 36a of the light receiving portion 36 is reduced. It is possible to detect by the optical sensor 33 that dust has passed through the air passage W. Therefore, as the amount of dust passing through the air passage W increases, the light receiving amount of the light receiving element 36a of the light receiving portion 36 decreases, so that the output signal from the optical sensor 33 is amplified by the amplifier 39. As the input signal input to the control means 37 by pulse shaping by the pulse shaper 40 becomes relatively small, the control means 37 passes through the inside of the air path W (at the position of the cleaning surface being cleaned). Excessive 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 predetermined amount, for example, by comparing the input signal with a preset threshold value (step). 2) When it judges that it is not more than the predetermined amount (less than the predetermined amount), the control means 37 judges whether the handle operation part 27 is operating by the motion detection means 45 (step 3). ).

In step 3, when the control means 37 determines that the handle operating part 27 is not operating (the handle operating part 27 is stopped), for example, the user grips the handle operating part 27. It is assumed that it is a cleaning state in which the air passage forming body 13 is left unattended, and the electric cleaner 11 (electric blower 18) is driven while the normal cleaning is not performed. The control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the first value for the predetermined electric blower which is the smallest predetermined minimum value, and sets the electric blower 18 as the first value. It operates with the predetermined 1st electric blower input (power 1) which is a lowest input (step 4).

In addition, in step 3, when the control means 37 judges that the handle operating part 27 is operating (the handle operating part 27 is not stopped), for example, a user uses the floor brush before and after as usual. Although the cleaning is carried out by reciprocating the 23, it is assumed that the amount of dust on the surface to be cleaned is a cleaning state or the like, and this control means 37 controls the input of the electric blower 18 set by the triac Tr1. The electric motor blower 18 is operated with a predetermined second electric blower input (power 2) larger than the first electric blower input, with the phase angle as the second value for the predetermined electric blower larger than the first value for the electric blower ( Step 5).

On the other hand, in step 2, when it is determined that the amount of dust detected by the optical sensor 33 is equal to or larger than the predetermined amount, the control means 37 determines whether the handle operating portion 27 is operated by the motion detection means 45. It is judged whether or not (step 6).

In step 6, when the control means 37 judges that the handle operating portion 27 is not operating (the handle operating portion 27 is stopped), for example, dust is partially stored in a wall or the like. Assuming that the place is in a cleaning state or the like, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to a predetermined electric blower third larger than the second value for the electric blower. Using the value, the electric blower 18 is operated with a predetermined third electric blower input (power 3) larger than the second electric blower input (step 7).

In addition, in step 6, when the control means 37 judges that the handle operating part 27 is operating (the handle operating part 27 is not stopped), for example, the amount of dust on the surface to be cleaned is large, and the user Assumes that the bottom brush 23 is reciprocated before and after as it is and is being cleaned, and this control means 37 is the phase of the input of the electric 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, with the angle being the fourth value for the predetermined electric blower larger than the third value for the electric blower (step 8). .

That is, the cleaning state is assumed based on the amount of dust detected by the photosensor 33 and the operating state of the handle operating unit 27 detected by the motion detecting means 45, and the control means corresponding to the assumed cleaning state. By controlling the driving (input) of the electric blower 18, the cleaning state of the user is highly precisely based on two pieces of information from the light sensor 33 and the information from the motion detecting means 45. It can be assumed as a road and can be cleaned with electric power suitable for the cleaning state.

Next, 2nd Embodiment is described with reference to FIG. 6 or FIG. In addition, about the structure and effect | action similar to the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

This 2nd Embodiment is equipped with the rotary brush 51 as a rotary cleaning body in the bottom brush 23 in the said 1st Embodiment.

That is, as shown in FIG. 7, the bottom brush 23 is rotatably provided with the rotation brush 51 in the horizontally long suction opening formed in the lower surface which opposes the surface to be cleaned of the case body 48. As shown in FIG. This rotary brush 51 is connected to the electric motor 52 accommodated in the case body 48 via the transmission means 53, such as a belt, and is rotationally driven by this electric motor 52. As shown in FIG.

The rotary brush 51 scrapes off the dirt which attracted or stuck to the surface to be cleaned by rotation. Although this rotating brush 51 can be made into arbitrary structures, it is preferable to provide cleaning members, such as a hair brush or a blade, for example.

As shown in FIG. 6, the motor 52 is phase-controlled by the control means 37 via the triac Tr2 as a motor control element. In addition, this electric motor 52 shall be turned on and off simultaneously with the on-off (corresponding to the on-off) of the vacuum cleaner 11 (electric blower 18). In addition, these control means 37 and the electric motor 52 (trial liquid Tr2) are electrically connected by the wiring which is not shown through the inside of the air path forming body 13.

Next, operation | movement of the said 2nd Embodiment is demonstrated, referring also to the matrix shown in FIG. 8, and the flowchart shown in FIG.

In step 3 of the first embodiment, when the control means 37 determines that the handle operating portion 27 does not operate (the handle operating portion 27 is stopped), for example, the user operates the handle operating portion. The cleaning which does not hold | maintain and does not carry out normal cleaning, for example leaving the air path forming body 13 while driving the vacuum cleaner 11 (electric blower 18). It is assumed that the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the first value for the electric blower, and sets the electric blower 18 to the first value. 1 operates at the electric blower input (power 1), and sets the phase angle of the input of the electric motor 52 set by the triac Tr2 as the first value for the predetermined electric motor which is the smallest predetermined minimum value. Operate 52 as the predetermined first motor input which is the lowest input In this way, the rotary brush 51 is rotated at a predetermined first rotational speed (rotational speed 1) which is the lowest rotational speed (step 11).

In addition, in step 3, when the control means 37 judges that the handle operating part 27 is operating (the handle operating part 27 is not stopped), for example, a user uses the floor brush before and after as usual. Although the cleaning is carried out by reciprocating the 23, it is assumed that the amount of dust on the surface to be cleaned is a cleaning state or the like, and this control means 37 controls the input of the electric blower 18 set by the triac Tr1. With the phase angle set as the second value for the electric blower, the electric blower 18 is operated as the second electric blower input (power 2), and the input of the electric motor 52 which is set by the triac Tr2. The rotary brush 51 is operated by operating the motor 52 with a predetermined second motor input larger than the first motor input by setting the phase angle of the motor as the second predetermined value for the motor larger than the first value for the motor. Predetermined second revolution greater than revolutions (times Be rotated to 2) (step 12).

In addition, in step 6, when the control means 37 judges that the handle operating part 27 is not operating (the handle operating part 27 is stopped), for example, it is partly dusty, such as a carpet wall. Is assumed to be a cleaning state of a place where the air is stored, 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 predetermined electric motor which operates the blower 18 as the said 3rd electric blower input (power 3), and sets the phase angle of the input of the electric motor 52 set by the triac Tr2 larger than the 2nd value for electric motors. By operating the electric motor 52 at a predetermined third electric motor input larger than the second electric motor input as the third value for the second motor, the rotary brush 51 is operated at a predetermined third speed larger than the second speed (rotation speed 3 (Step 13).

Then, in step 6, when the control means 37 determines that the handle operating portion 27 is operating (the handle operating portion 27 is not stopped), for example, the amount of dust on the surface to be cleaned is large, and the user Is assumed to be a cleaning state or the like that is cleaned by reciprocating the bottom brush 23 before and after as usual, and this control means 37 controls the input of the electric blower 18 set by the triac Tr1. With the phase angle set as the fourth value for the electric blower, the electric blower 18 is operated as the fourth electric blower input (power 4), and the input of the electric motor 52 to be set by the triac Tr2. The rotary brush 51 is operated as a third by operating the motor 52 with a predetermined fourth motor input larger than the third motor input by setting the phase angle of the motor as the fourth value for the predetermined motor larger than the third value for the motor. The predetermined fourth rotation speed greater than the rotation speed ( It rotates to transfer 4) (step 14).

Thus, the control means 37 assumes the cleaning state based on the amount of dust detected by the optical sensor 33, and the operation | movement of the handle operation part 27 detected by the motion detection means 45, and assumed By controlling the driving of the electric blower 18 and the electric motor 52 (rotary brush 51) in correspondence with the cleaning state, not only the electric blower 18 but also the electric motor 52 (rotary brush 51) are cleaned. Since it can be driven in a state suitable for a state, it can be cleaned with the electric power suitable for a cleaning state, and energy saving is not only possible, but the dust of the surface to be cleaned can be scraped off by the electric motor 52 (rotary brush 51). , Cleaning performance can be improved more.

Next, 3rd Embodiment is described with reference to FIGS. 10-13. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

In this 3rd Embodiment, in the said 1st Embodiment, the ground detection means 55 which detects the ground state of this bottom brush 23 is arrange | positioned at the bottom brush 23. As shown in FIG.

As shown in FIG. 11, the ground detection means 55 is movable in the opening part 56 formed in the lower surface which opposes the surface to be cleaned of the case body 48. As shown in FIG. In addition, the ground detection means 55 has a wheel 57 as a ground portion and a switch not shown not switched on and off by grounding / ungrounding of the wheel 57, and the wheel 57 The support member 59 is pivotally rotatable, and the support member 59 is pivotally rotatable to the case body 48. Then, when the bottom brush 23 contacts (grounds) the surface to be cleaned, the wheel 57 contacts the surface to be cleaned so that the wheel 57 rotates together with the supporting member 59 to be stored in the opening 56. When the pivoted support member 59 turns on the changeover switch, the ground of the bottom brush 23 is detected, and when the bottom brush 23 is spaced apart from the surface to be cleaned (if it is not grounded), the support member 59 The wheel 57 protrudes from the opening 56, and the support member 59 is spaced apart from the changeover switch, and the non-grounding of the bottom brush 23 is detected by switching off the changeover switch.

In addition, the ground detection means 55 is electrically connected to the control means 37, as shown in FIG. 10, and the control means 37 is switched on and off through the switching switch of the ground detection means 55. FIG. It is comprised so that the grounding / ungrounding of this floor brush 23 can be recognized. In addition, the ground detection means 55 and the control means 37 are electrically connected by the wiring which is not shown in the figure which passes through the inside of the air path formation body 13. Thus, for example, when the bottom brush 23 is removed from the extension pipe 22, or the extension pipe 22 and the bottom brush 23 are removed from the handle operating part 27, and another suction port, for example, an elongated nozzle or the like, is removed. Is connected to the handle operating section 27, the electrical connection between the ground detecting means 55 and the control means 37 is cut off, so that the control means 37 is not grounded by the bottom brush 23. It is configured to judge. That is, the ground detection means 55 indirectly detects whether the ground brush 23 is grounded or ungrounded, thereby indirectly using the bottom brush 23 or removing the bottom brush 23 and using another suction port. It has the function of the connection detection means to judge. For this reason, below, it is assumed that the grounding / ungrounding which the control means 37 detects by the ground detection means 55 also includes the connection / nonconnection of the floor brush 23. As shown in FIG.

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. 13.

First, in step 3, when the control means 37 determines that the handle operating portion 27 does not operate (the handle operating portion 27 is stopped), the control means 37 includes a ground detection means ( 55, it is judged whether or not the bottom brush 23 is earthed (step 21).

When it is determined in step 21 that the bottom brush 23 is not grounded, the control means 37 has a small amount of dust on the surface to be cleaned, for example, and the user has the bottom brush 23 (and the extension pipe 22). )) And other suction inlets such as elongated nozzles or the like, or the user does not grip the handle operation unit 27 and does not clean as usual, for example, an electric vacuum cleaner 11 (The electric blower 18 in which the air blower 18 is being driven and the air passage forming body 13 is left in a cleaned state or the like, and the control means 37 is set by the triac Tr1). The electric blower 18 is operated by the first electric blower input (power 1) by setting the phase angle of the input of the electric blower as the first value for the electric blower (step 22).

In addition, when it is determined in step 21 that the bottom brush 23 is grounded, the control means 37 has a small amount of dust on the surface to be cleaned, for example, but the bottom brush 23 is placed on the surface to be cleaned. Assuming that it is grounded and cleaned in a place where dust is partially stored, such as a wall, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 for the electric blower. Using the second value, the electric blower 18 is operated by the second electric blower input (power 2) (step 23).

In addition, in step 3, when the control means 37 judges that the handle operating part 27 is operating (the handle operating part 27 is not stopped), the control means 37 is performed similarly to step 21. The ground detecting means 55 determines whether the bottom brush 23 is grounded (step 24).

And when it is determined in this step 24 that the bottom brush 23 is not grounded, the control means 37, for example, has a small amount of dust on the surface to be cleaned, for example, the bottom brush 23 (and It is assumed that the extension pipe 22 is removed, and the cleaning state is being cleaned by connecting another suction port such as an elongated nozzle and the like, and the control means 37 of the electric blower 18 set by the triac Tr1. Using the phase angle of the input as the second value for the electric blower, the electric blower 18 is operated with the second electric blower input (power 2) (step 25).

In addition, when it is determined in step 24 that the bottom brush 23 is grounded, the control means 37 cleans by grounding the bottom brush 23 to the surface to be cleaned, although the amount of dust on the surface to be cleaned is small, for example. Assuming that the cleaning state or the like is being performed, 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, and the electric blower 18. Is operated by the third electric blower input (power 3) (step 26).

On the other hand, when the control means 37 determines that the handle operation part 27 is not operating in step 6 (the handle operation part 27 is stopped), it is the control means 37 similarly to step 21, 24. ) Determines whether or not the ground brush 23 is grounded by the ground detecting means 55 (step 27).

And in this step 27, when it is judged that the floor brush 23 is not grounded, the control means 37 is a floor brush 23, for example in the place where the clearance gap between furniture and a wall is narrow, for example. ), Another suction inlet such as an elongated nozzle is connected, and dust stored in the suction air is sucked in, so that it is assumed to be a predetermined time, a cleaning state in which the suction inlet is stopped and cleaned. 37) sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the 3rd value for the said electric blower, and turns the electric blower 18 into the said 3rd electric blower input (power 3). It operates (step 28).

In addition, when it is determined in step 27 that the bottom brush 23 is grounded, the control means 37, for example, the cleaning state of cleaning the corners, walls, etc. of the surface to be cleaned by the bottom brush 23. Assume that the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the fourth value for the electric blower, and sets the electric blower 18 to the fourth value. It operates by electric blower input (power 4) (step 29).

In addition, in step 6, when the control means 37 determines that the handle operating part 27 is operating (the handle operating part 27 is not stopped), it is the control means similarly to step 21, 24, 27. 37 determines whether or not the ground brush 23 is grounded by the ground detecting means 55 (step 30).

And in this step 30, when it is judged that the floor brush 23 is not grounded, the control means 37 is a floor brush 23, for example with respect to a wide range of to-be-cleaned surfaces, such as on the shelf with many dust amounts. ), And the extension means 22 is assumed to be a cleaning state or the like that is being cleaned using another suction port such as a furniture brush, and the control means 37 is an electric blower (set by Triac Tr1). By setting the phase angle of the input of 18) as the fourth value for the electric blower, the electric blower 18 is operated by the fourth electric blower input (power 4) (step 31).

In addition, when it is determined in step 30 that the floor brush 23 is grounded, the control means 37 has a large amount of dust on the surface to be cleaned, for example, and the user grounds the floor brush 23 to the front and rear as usual. Assuming that the bottom brush 23 is reciprocated and cleaned, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 to the electric blower agent. The electric blower 18 is operated with the predetermined fifth electric blower input (power 5), which is the maximum input larger than the fourth electric blower input, as the fifth value for the predetermined electric blower that is the maximum value larger than the four value (step 5). 32).

In this way, the ground state (connected state) of the suction port such as the bottom brush 23 or the elongated nozzle is detected by the ground detecting means 55, and the control means 37 uses the optical sensor 33. A cleaning state is assumed based on the amount of dust detected, the operation of the handle operating portion 27 detected by the motion detection means 45 and the ground state (connected state) of the suction port detected by the ground detection means 55, By controlling the driving of the electric blower 18 in response to the assumed cleaning state, the cleaning state of the user is determined by the information from the optical sensor 33 and the information from the motion detection means 45 and the ground detection means 55. On the basis of the three pieces of information from the information from the above, it is possible to assume a higher precision, and the cleaning state can be performed at a suitable electric power, thereby further saving energy. That is, for example, when the bottom brush 23 is grounded (when it is connected), the input of the electric blower 18 is less than when the bottom brush 23 is not grounded (when not connected). Since the power (suction input) is increased, the opening area is narrower than that of the floor brush 23 and the electric blower, for example, when cleaning the surface to be cleaned such as the floor surface using the floor brush 23 requiring power. The control means 37 can discriminate | determine when cleaning using the inlet body, such as an elongate nozzle, whose power of (18) may be small, and can be set suitably by the input of the electric blower 18. As shown in FIG.

In addition, in the said 1st Embodiment and 3rd Embodiment, although the bottom brush 23 may be provided with the rotation brush 51 and the electric motor 52 of the said 2nd Embodiment, the electric motor 52 is carried out. (Rotation brush 51) shall be controlled independently from the electric blower (18).

Next, 4th Embodiment is described with reference to FIGS. 14-16. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

As shown in FIG. 14, this fourth embodiment includes the ground detection means 55 of the third embodiment in the second embodiment.

Referring to the matrix shown in FIG. 15 and the flowchart shown in FIG. 16, when it is determined in step 21 that the bottom brush 23 is not grounded, for example, the amount of dust on the surface to be cleaned is small, It is assumed that the user leaves the air passage forming body 13 in a state in which the user has dropped the bottom brush 23 against the surface to be cleaned, and the control means 37 is an electric blower set by the triac Tr1. By setting the phase angle of the input of (18) as the first value for the electric blower, operating the electric blower 18 as the first electric blower input (power 1), and setting by the triac Tr2. The phase angle of the input of the electric motor 52 is set to 0, and the electric motor 52, ie, the rotating brush 51, is stopped (step 41).

In addition, when it is determined in step 21 that the bottom brush 23 is grounded, the control means 37 grounds the bottom brush 23 to the surface to be cleaned, for example, and presses the wall or the like with a small amount of dust to stop the cleaning. It is assumed that 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, and sets the electric blower 18 as the second value. The motor 52 is operated as the second value for the electric motor by operating the electric blower input (power 2) and setting the phase angle of the input of the electric motor 52 set by the triac Tr2 as the second value for the electric motor. By operating by the electric motor input, the rotating brush 51 is rotated by the said 2nd rotation speed (rotation speed 2) (step 42).

Similarly, when it is determined in step 24 that the bottom brush 23 is not grounded, the control means 37 has a small amount of dust on the surface to be cleaned, for example, but the bottom brush 23 (and the extension pipe, for example). (22) is removed, and is assumed to be a cleaning state or the like that is being cleaned using another suction port such as an elongated nozzle, and the control means 37 inputs the electric blower 18 set by the triac Tr1. Of the electric motor 52 which operates the electric blower 18 as the said 2nd electric blower input (power 2), and sets it with the triac Tr2, making the phase angle of the electric blower into the 2nd value for the said electric blower. The electric motor 52, that is, the rotary brush 51, is stopped by setting the phase angle of the input to zero (step 43).

In addition, when it is determined in step 24 that the bottom brush 23 is grounded, the control means 37 cleans by grounding the bottom brush 23 to the surface to be cleaned, although the amount of dust on the surface to be cleaned is small, for example. Assuming that the cleaning state or the like is being performed, 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, and the electric blower 18. Is operated as the third electric blower input (power 3), and the motor 52 is set as the third value for the electric motor by setting the phase angle of the input of the electric motor 52 set by the triac Tr2. By operating with the third electric motor input, the rotary brush 51 is rotated at the third rotational speed (rotational speed 3) (step 44).

In addition, in step 27, when it is judged that the floor brush 23 is not grounded, the control means 37, for example, in the place where the clearance gap between furniture and a wall is narrow, for example, the floor brush 23 And other suction inlets such as elongated nozzles are connected to suck in the dust stored by the suction air volume, so that the control unit 37 assumes a predetermined time, a cleaning state in which the inlet is stopped and cleaned. ) Operates the electric blower 18 as 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. In addition, the phase angle of the input of the electric motor 52 set by the triac Tr2 is made into 0, and the electric motor 52, ie, the rotating brush 51, is stopped (step 45).

In addition, in step 27, when it is judged that the floor brush 23 is earthed, the control means 37, for example, the cleaning state which tries to clean the corner of a surface to be cleaned, a wall, etc. with the floor brush 23, for example. Assume that the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the fourth value for the electric blower, and sets the electric blower 18 to the fourth value. The motor 52 is operated by the electric blower input (power 4) and the phase angle of the input of the motor 52 set by the triac Tr2 is set as the fourth value for the electric motor. By operating with the input, the rotary brush 51 is rotated at the fourth rotational speed (rotational speed 4) (step 46).

And in step 30, when it is judged that the bottom brush 23 is not grounded, the control means 37, for example, with respect to a wide range of to-be-cleaned surfaces, such as on the shelf with a lot of dust, for example, the bottom brush 23 (And extension pipe 22) Assuming that the cleaning state is being cleaned using another suction port such as a furniture brush or the like, the control means 37 sets the electric blower 18 set by the triac Tr1. The electric motor 52 which operates the electric blower 18 as the said 4th electric blower input (power 4), sets the phase angle of the input of the electric blower as a 4th value for the said electric blowers, and sets it by the triac Tr2. ), The electric motor 52, that is, the rotary brush 51, is stopped (step 47).

In addition, when it is determined in step 30 that the floor brush 23 is grounded, the control means 37 has a large amount of dust on the surface to be cleaned, for example, and the user grounds the floor brush 23 to the front and rear as usual. Assuming that the bottom brush 23 is reciprocated and cleaned, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 for the electric blower. By setting the fifth value, 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. The rotary brush 51 is rotated fourth by operating the motor 52 as a predetermined fifth motor input which is the maximum input larger than the fourth motor input, using the fifth value for the predetermined motor that is the maximum value larger than the fourth value. Number of revolutions greater than To define a fifth rotational rotated by (revolutions 5) (step 48).

In this way, the ground state (connected state) of the suction port such as the bottom brush 23 or the elongated nozzle is detected by the ground detecting means 55, and the control means 37 uses the optical sensor 33. The electric blower 18 corresponds to the amount of dust detected, the operation of the handle operating portion 27 detected by the motion detection means 45, and the ground state (connected state) of the suction port detected by the ground detection means 55; By controlling the drive of the electric motor 52 (rotation brush 51), it is possible to assume a user's cleaning state with high precision, and it can clean with a suitable electric power by the cleaning state, and further energy saving is attained. That is, for example, when the bottom brush 23 is grounded (when it is connected), the input of the electric blower 18 is less than when the bottom brush 23 is not grounded (when not connected). Power, so that, for example, when cleaning the surface to be cleaned such as the floor surface using the floor brush 23, which requires power, the elongated nozzle may have a smaller power compared to the floor brush 23. The control means 37 can identify the cleaning time using the suction inlet body, etc., and it can set suitably by input of the electric blower 18. In addition, when the ground detecting means 55 detects ungrounding (no connection) of the floor brush 23, the electric motor 52 (rotary brush 51) is stopped, thereby suppressing unnecessary power consumption and further. Energy saving can be achieved.

Next, a fifth embodiment will be described with reference to FIGS. 17 and 18. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

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

Specifically, in the fifth embodiment, the control of the following steps 51 to 54 is performed instead of the control of the steps 45 to 48 of the fourth embodiment.

That is, with reference to the matrix shown in FIG. 17 and the flowchart shown in FIG. 18, when it is determined in step 27 that the floor brush 23 is not grounded, the control means 37 is a furniture and a wall, for example. In a place with a narrow gap, for example, the bottom brush 23 is removed, and another suction port such as an elongated nozzle is connected to suck in the dust stored by the suction air volume. Assuming that the sphere is stopped and cleaned, the control means 37 sets 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 blower 18 is operated by the fifth electric blower input (power 4), and the phase angle of the input of the motor 52 set by the triac Tr2 is set to 0, thereby rotating the motor 52, that is, rotating. Still life brush (51) Thereby (step 51).

In addition, when it is determined in step 27 that the bottom brush 23 is grounded, the control means 37, for example, the bottom brush 23 with respect to the position of the corner of the surface to be cleaned or the wall with a large amount of dust. Is assumed to be a cleaning state or the like which is intensively cleaned by grounding, and the control means 37 sets 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 electric blower 18 is operated as 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 as the fifth value for the electric motor. By operating the electric motor 52 at the fifth electric motor input, the rotary brush 51 is rotated at the fifth rotation speed (rotation speed 5) (step 52).

In addition, when it is judged in step 30 that the bottom brush 23 is not grounded, the control means 37, for example, with respect to a wide range of to-be-cleaned surfaces, such as on the shelf with a lot of dust, for example, the floor brush 23 (And extension pipe 22) Assuming that the cleaning state is being cleaned using another suction port such as a furniture brush or the like, the control means 37 sets the electric blower 18 set by the triac Tr1. The electric motor 52 which operates the electric blower 18 as the said 3rd electric blower input (power 3), sets it as the 3rd value for the said electric blowers, and sets it by the triac Tr2. ), The electric motor 52, that is, the rotary brush 51, is stopped (step 53).

Then, in step 30, when it is determined that the bottom brush 23 is grounded, the control means 37 has a large amount of dust on the surface to be cleaned, for example, and the user grounds the bottom brush 23 to back and forth as usual. Assuming that the bottom brush 23 is reciprocated and cleaned, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 for the electric blower. By setting the fourth value, the electric blower 18 is operated with the fourth electric blower input (power 4), and the phase angle of the input of the electric motor 52 set by the triac Tr2 is set for the electric motor. By setting the fourth value to operate the electric motor 52 with the fourth electric motor input, the rotary brush 51 is rotated at the fourth rotational speed (rotational speed 4) (step 54).

Thus, when the amount of dust detected by the optical sensor 33 is more than a predetermined amount, and it is detected by the motion detection means 45 that the handle operation part 27 is not operating, for example, a user will be cleaned. The control means 37 assumes that the cleaning state is intensively cleaned by using the suction port such as the bottom brush 23 or the elongated nozzle with respect to the position of the corner, the wall, or the like, and the control means 37 At least by increasing the input of the electric blower 18 to a maximum input that is set in advance according to the type of the vacuum cleaner 11 or the like, so as to effectively clean dust in response to the cleaning state of the user. It becomes possible, and usability improves.

In addition, the amount of dust detected by the photosensor 33 is not less than a predetermined amount, and the motion detecting means 45 detects that the handle operating portion 27 is not operating, and the ground detecting means 55 When the grounding of the floor brush 23 is detected, for example, the cleaning is performed by intensively cleaning the ground brush 23 by grounding the floor brush 23 with respect to the corner of the surface to be cleaned or the wall. The control means 37 assumes a state, and this control means 37 advances the input of the electric motor 52 with the electric blower 18 relatively, specifically, according to the kind of the vacuum cleaner 11, etc. in advance. By driving with the maximum input set, respectively, dust can be cleaned more effectively corresponding to the cleaning state of a user, and usability is further improved.

That is, when only the motion detection means 45 is provided, there exists a possibility that the control means 37 may reduce an input when it detects that the handle operation part 27 is not operating, but in this embodiment, an optical sensor ( 33) and the motion detection means 45, the user can concentrate on the position of the corner or wall of the surface to be cleaned, using the suction port such as the floor brush 23 or the elongated nozzle. Even when the cleaning state is being cleaned, it can cope. Therefore, the electric blower 18 and / or the electric motor 52 (rotation brush 51) can be driven by a suitable electric power by a cleaning state, and can reliably clean. In other words, by providing both the optical sensor 33 and the motion detection means 45, the cleaning state can be detected complementarily and can be cleaned effectively.

Next, a sixth embodiment will be described with reference to FIGS. 19 and 20. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

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

Specifically, in the sixth embodiment, the control of the following steps 61 to 66 is performed instead of the control of the steps 43 to 48 of the fourth embodiment.

That is, with reference to the matrix shown in FIG. 19 and the flowchart shown in FIG. 20, when it is determined in step 24 that the bottom brush 23 is not grounded, it adheres to the inside of the to-be-cleaned surface, such as a chassis, for example. It is assumed that the dust is a cleaning state requiring a relatively small amount of dust but having a strong power, for example, when the bottom brush 23 is removed and other inlet bodies such as a thin nozzle are connected and cleaned. 37) sets the phase angle of the input of the electric blower 18 set by the triac Tr1 as the 5th value for the said electric blower, and turns the electric blower 18 into the 5th electric blower input (power 4). While operating, the phase angle of the input of the electric motor 52 set by the triac Tr2 is set to 0, and the electric motor 52, that is, the rotating brush 51, is stopped (step 61).

In addition, in step 24, when it is judged that the bottom brush 23 is grounded, the control means 37 removes dust, such as a bundle of yarn stuck to the surface to be cleaned, such as a carpet, for example. Assuming that it is a cleaning state or the like that is to be moved little by little, the control means 37 sets 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 blower 18 is operated as the fifth electric blower input (power 5), and the phase angle of the input of the motor 52 set by the triac Tr2 is set as the fifth value for the electric motor. By operating the 52 as the fifth electric motor input, the rotary brush 51 is rotated at the fifth rotational speed (rotational speed 5) (step 62).

In addition, in step 27, when it is judged that the floor brush 23 is not grounded, the control means 37, for example, in the place where the clearance gap between furniture and a wall is narrow, for example, the floor brush 23 And other suction inlets such as elongated nozzles are connected to suck in the dust stored by the suction air volume, so that the control unit 37 assumes a predetermined time, a cleaning state in which the inlet is stopped and cleaned. ) Operates the electric blower 18 as 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. In addition, the phase angle of the input of the electric motor 52 set by the triac Tr2 is set to 0, and the electric motor 52, ie, the rotating brush 51, is stopped (step 63).

In addition, in step 27, when it is judged that the floor brush 23 is earthed, the control means 37, for example, the cleaning state which tries to clean the corner of a surface to be cleaned, a wall, etc. with the floor brush 23, for example. Assuming that 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, and sets the electric blower 18 to the third value. The motor 52 is operated by the electric blower input (power 3), the phase angle of the input of the electric motor 52 set by the triac Tr2 is set as the third value for the electric motor, and the electric motor 52 is the third electric motor. By operating by input, the rotary brush 51 is rotated by the said 3rd rotation speed (rotation speed 3) (step 64).

In addition, when it is judged in step 30 that the bottom brush 23 is not grounded, the control means 37, for example, with respect to a wide range of to-be-cleaned surfaces, such as on the shelf with a lot of dust, for example, the floor brush 23 (And extension pipe 22) is assumed to be a cleaning state or the like that is being cleaned using another suction port such as a furniture brush, and the control means 37 inputs the electric blower 18 set by Triac Trl. Of the electric motor 52 which operates the electric blower 18 as the said 3rd electric blower input (power 3), and sets it by the triac Tr2, making the phase angle of the electric blower the 3rd value for the said electric blower. The electric motor 52, that is, the rotary brush 51, is stopped by setting the phase angle of the input to zero (step 65).

In addition, when it is determined in step 30 that the floor brush 23 is grounded, the control means 37 has a large amount of dust on the surface to be cleaned, for example, and the user grounds the floor brush 23 to the front and rear as usual. Assuming that the bottom brush 23 is reciprocated and cleaned, the control means 37 sets the phase angle of the input of the electric blower 18 set by the triac Tr1 for the electric blower. By setting the fourth value, the electric blower 18 is operated with the fourth electric blower input (power 4), and the phase angle of the input of the electric motor 52 set by the triac Tr2 is set for the electric motor. By setting the fourth value to operate the electric motor 52 with the fourth electric motor input, the rotary brush 51 is rotated at the fourth rotational speed (rotational speed 4) (step 66).

Thus, in the case where the control means 37 detects that the amount of dust detected by the optical sensor 33 is equal to or less than the predetermined amount, and the handle operation unit 27 is operated by the motion detection means 45, it is yes. For example, the control means 37 is a cleaning state in which dust such as a bundle of threads that the user sticks to the surface to be cleaned such as a rug and is hard to be peeled off is cleaned using the bottom brush 23 or a suction port such as an elongated nozzle. Assuming that this control means 37 drives at least the input of the electric blower 18 relatively, for example, it drives by the maximum input preset in advance according to the kind of the vacuum cleaner 11, etc. Corresponding to the state, dust can be cleaned effectively, and the ease of use is improved.

In addition, the amount of dust detected by the photosensor 33 is not more than a predetermined amount, and the motion detecting means 45 detects that the handle operating portion 27 is operating, and the ground detecting means 55 is bottomed out. When the grounding of the brush 23 is detected, for example, the cleaning state in which the user is cleaning the dust such as a bundle of yarns that the user sticks to the surface to be cleaned such as a rug and is hard to remove, is used by the floor brush 23. The control means 37 are assumed, and the control means 37 is set in advance in accordance with the type of the electric cleaner 11 and the like. By driving each of the maximum inputs, the dust can be cleaned more effectively in response to the cleaning state of the user, and the usability is further improved.

That is, when only the optical sensor 33 is provided, when cleaning the to-be-cleaned surface, such as a carpet in which a thread bundle etc. adhere, for example, it is judged that dust amount is more than predetermined amount by suction of dust initially, but only a thread bundle is carried out. If it remains on the surface to be cleaned, the amount of dust may be incorrectly judged to be less than or equal to a predetermined amount, and the control means 37 may lower the input. The above-mentioned user can cope even when the cleaning state is cleaning the dust such as the thread sticking to the surface to be cleaned such as a carpet by using a bottom brush 23 or an inlet such as an elongated nozzle. have. Therefore, the electric blower 18 and / or the electric motor 52 (rotation brush 51) can be driven by a suitable electric power by a cleaning state, and can reliably clean. In other words, by providing both the optical sensor 33 and the motion detection means 45, the cleaning state can be detected complementarily and can be cleaned effectively.

In addition, the control of step 51 of the said 5th embodiment and the control of step 61 of a 6th embodiment are applicable also in the case of the structure which does not have the ground detection means 55 or the floor brush 23, respectively. That is, instead of step 7 of the first embodiment or step 13 of the second embodiment, step 51 of the fifth embodiment may be controlled, or step 5 of the first embodiment or the above-mentioned. Instead of step 12 of the second embodiment, the control of step 61 of the sixth embodiment may be performed to increase the input of the electric blower 18 at least. Moreover, you may combine the control of the said 5th embodiment, and the control of a 6th embodiment.

And according to at least one embodiment described above, the control means 37 is based on the amount of dust detected by the optical sensor 33 and the operation of the handle operating part 27 detected by the motion detection means 45. By controlling the driving of the electric blower 18 at least, it is possible to assume the user's cleaning state with high accuracy based on at least two pieces of information from the light sensor 33 and the information from the motion detecting means 45. It can clean with the electric power suitable for the cleaning state, and energy saving is attained.

In addition, in each said embodiment, although the handle operation part 27 was supposed to hold and operate the air path formation body 13, what is called what connected the bottom brush 23 to the lower part of the vacuum cleaner main body 12, for example. In the case of an upright type vacuum cleaner or the like, the vacuum cleaner main body 12 may be configured to be gripped.

In addition, although each electric blower input and each electric motor input were demonstrated using the input common in each embodiment, if it maintains the magnitude relationship with each other, it may be different input for every embodiment.

And although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are not only included in the scope and spirit of the invention, but also included in the invention described in the claims and their equivalents.
