The control means 110 controls the electric blower 60 for adjusting the suction air flow according to the type of the surface to be cleaned, that is, the type of a carpet, a tatami mat or a plate floor, and adjusts the suction air flow according to the clogged state of the filter 15a. Control of the electric blower 60, and power supply or power supply to the brush motor via the suction hose 14a from the cleaner side when using a floor brush provided with a rotating brush rotated by a brush motor (not shown). The control by operating the control switch S3 provided on the grip tube 14b of the stopped suction hose 14a and the cleaner body A So that the various control of the control for driving or stopping the electric blower 60 is made by digits with power switch S1 either closing or opening of the hand operation switch S2 provided in the Nigikan 14b.

The air purifier mode is an operation mode in which the vacuum cleaner is operated when the electric vacuum cleaner is used as the air purifier.
By adjusting 0, the suction air amount of the electric blower 60 is adjusted to adjust the suction amount of the air to be cleaned.

As described above, the control in the vacuum cleaner mode for functioning as a vacuum cleaner and the control in the air cleaner mode for functioning as an air cleaner are greatly different. Therefore, in the operation state in one of the modes, that is, in the operation continuation state, even if the electric blower 60 is erroneously switched to the other mode, the electric blower 60 continues to operate. Even if the user performs the control operation in one of the modes, the user cannot perform the control in this mode. Therefore, it is not preferable that the user misunderstands that the vacuum cleaner is out of order. Further, if it is configured that the control operation of the one mode can be performed after the mode is switched to the other mode, for example, even though the user has selected the air purifier mode, the grip tube 14b When the control switch S3 is operated, a problem such as that the rotating brush provided on the floor brush is rotationally driven occurs.

In order to solve this problem, in the first embodiment, when one of the modes is selected by the switching means 57 and this operation causes the cleaner, that is, the electric blower 60 to operate, the mode is selected. When the mode is switched to the other mode, the electric blower 60 is stopped, and control is performed so that the user can confirm that the mode has been switched to the other mode.

Next, control of the vacuum cleaner will be described with reference to a control block diagram shown in FIG. As shown in the figure, the control means 110 is connected to a switching means 57 switched by the operation knob 56 and a drive circuit 111 for the electric blower 60, that is, the brushless motor 61. Further, a driving state detecting means 112 for detecting whether or not the electric blower 60 is in a driving state is connected to the control means 110. The drive state detecting means 112 detects, for example, a drive current of the brushless motor 61 and outputs the detection signal to the control means 11.
It is composed of a current detecting means for sending to zero. The operation knob 56 operates the switching means 57 and the valve means 50 in conjunction with each other.

When the operation knob 56 is rotated counterclockwise in FIG. 1 so as to select the cleaner mode, the switching means 57 selects the cleaner mode. Then, the valve means 50 pivots counterclockwise as described above, and the valve 53 closes the intake port 24a, and the valve 52 pivots to a position parallel to the support plate 58 and the intake port 23a.
open. In this state, the electric blower 60 is driven to operate the cleaner in the cleaner mode. When the operation knob 56 is rotated clockwise in FIG. 1 to select the air purifier mode, the switching means 57 selects the air purifier mode. Then, the valve means 50 rotates clockwise as described above, and the valve 52 is
a, and the valve 53 rotates to a position parallel to the support plate 58 to open the intake port 24a. Then, in this state, the electric blower 60 is driven to operate the cleaner in the air purifier mode.

When the electric blower 60 is in a driving state,
A drive current is flowing through the brushless motor 61, and the drive current is detected by the drive state detection unit 112,
The detection signal is sent to the control means 110. When the electric blower 60 is in the driving state under one of the modes, for example, when the electric blower 60 is erroneously switched to the other mode, the switching is detected by the control unit 110, and the driving operation detecting unit Electric blower 6 from 112
The control means 110 controls the drive circuit 111 to stop the electric blower 60 based on the detection signal indicating that the drive state is 0. By stopping the electric blower 60, the user can clearly recognize that the mode has been switched from one mode to the other mode.

Next, the operation of the vacuum cleaner constructed as described above will be described.

First, when the vacuum cleaner is used as an electric vacuum cleaner, the operation knob 56 is rotated counterclockwise in FIG. In conjunction with this selection operation, that is, the rotation operation of the operation knob 56, the valve means 50 rotates counterclockwise, and the intake port 24a
Is closed by the valve 53 and the valve 52 opens the intake port 23a.
a and the vent hole 18 are in communication with each other. And the inlet 1
When the hand operation switch S2 provided on the operation unit 14c of the grip tube 14b of the suction hose 14a connected to the suction hose 3 is closed, the electric blower 60 is driven and dust is sucked in along with the suction airflow from a floor brush (not shown). The suction airflow, which is captured by the dust collection bag and the dust collection device 15 (not shown) and from which dust is removed, is sucked into the ventilation hole 18, the first air passage 30, the air inlet 23 a, and the electric blower 60. The exhaust air that has been exhausted is exhausted to the outside of the cleaner body A through the exhaust port 7a, the filter 82 of the air cleaning filter 80, and the exhaust hole 91.

In such a use state, the intake port 24a
The outer peripheral edge of the valve 53 that is closed is positioned and pressed by the edge portion of the intake port 24a, that is, the restricting portion, by the negative pressure generated by the suction action of the electric blower 60, so that the non-communication state, that is, the first The air passage 30 is reliably held at the air passage blocking position where the air passage 30 communicates.

Then, when the exhaust air passes through the filter 82, extremely fine dust contained in the exhaust air is
Since the exhaust air is removed by the filter 82, the exhaust air is cleaned and discharged to the outside, which is extremely sanitary.
An opening / closing lid 95 for closing the opening 93 of the storage chamber 92.
The wing 95b rotates counterclockwise by receiving the wind pressure of the exhaust air from its wing 95b, and the opening 93 is opened. Therefore, the deodorant 100 in the storage room 92 volatilizes and is discharged together with the exhaust air from the exhaust hole 91, thereby deodorizing the exhaust air and the indoor odor. Further, when the cleaning operation is completed and the electric blower 60 is stopped, the exhaust air stops flowing, so that the opening 93 is closed by the opening / closing lid 95. Thus, volatilization of the deodorant 100 is suppressed, and the consumption of the deodorant 100 can be prevented.

In the vacuum cleaner mode, the air inlet 24a
Is closed by the valve 53, that is, the second air passage 40 is closed, so that the air inlet 24a and the air inlet 5 are not communicated with each other, and the air to be cleaned is not sucked.

Next, when the cleaner is to function as an air cleaner, the operation knob 56 is rotated clockwise in FIG. 1 and the switching means 57 selects the air cleaner mode. The valve means 50 rotates clockwise in conjunction with the rotation operation of the operation knob 56 by this selection operation, and the intake port 23 is rotated.
a is closed by the valve 52 and the valve 53 opens the intake port 24a.
4a and the inlet 5 are in communication. Then, when the power switch S1 is closed, the electric blower 60 is driven, and the air in the room, that is, the air to be cleaned is sucked through the suction port 5, and at this time, large dust and the like are removed by the filter 35. The sucked clean air is sucked into the second air passage 40, the intake port 24a, and the electric blower 60, and the exhaust air exhausted from the electric blower 60 is exhausted by the exhaust port 7a and the filter of the air purifying filter 80. 82, the air is exhausted to the outside of the cleaner main body A through the exhaust hole 91.

In such a use, the intake port 23
The outer peripheral edge of the valve 52 closing the valve a is positioned and pressed by the edge of the intake port 23a, that is, the restricting portion, by the negative pressure generated by the suction action of the electric blower 60. Is reliably held at the air path blocking position for blocking the air path 40.

Further, when the exhaust air passes through the filter 82, extremely fine dust contained in the exhaust air is removed by the filter 82, so that the exhaust air, that is, the air to be cleaned is cleaned and Is discharged. This cleans the indoor air.

In the operation in the air purifier mode, as in the operation in the vacuum cleaner mode, the storage room 92 is operated.
The opening / closing lid 95 closing the opening 93 of the
In response to the wind pressure of the exhaust air, it rotates counterclockwise due to the wind pressure of the exhaust air, and the opening 93 is opened. Deodorization such as unpleasant odor in the room. In addition, when the electric blower 60 is stopped after the cleaning operation is completed, the exhaust air stops flowing, so that the opening 93 is closed by the opening / closing lid 95 and the deodorant 1
Since the volatilization of the deodorant 100 is suppressed, the consumption of the deodorant 100 can be prevented.

In this air purifier mode, the intake port 2
3a is closed by a valve 52, i.e.
Is closed, the suction port 23a and the ventilation hole 18 are not communicated with each other, and no suction airflow flows from the suction port 13.

If, for example, an accidental switching to the vacuum cleaner mode occurs while the air is being cleaned as the air purifier mode, the control means 1 as described above.
Since the electric blower 60 is stopped by 10, the user can reliably recognize that an erroneous operation has been performed. Therefore,
The air purifier mode is selected again and the electric blower 60 is changed.
Can be driven to clean the air.

As described above, the vacuum cleaner includes the first air passage 30 that connects the suction side of the electric blower 60 and the dust collection chamber 10,
A second air path 40 is formed for communicating the intake side and the intake port 5 as an air inlet to be cleaned, and both air paths 30 and 40 are selectively communicated with the intake side by a valve means 50. By doing so, the same electric blower 60 can be shared and switched between the cleaning function and the air cleaning function, so that the cost can be reduced and the size and weight of the cleaner itself can be reduced.

The switching means 57 can be used to select one of a cleaner mode for functioning as a cleaner and an air cleaner mode for functioning as an air cleaner, and the valve is operated in conjunction with the switching of the switching means 57. Since the means 50 is switched so that the air path corresponding to the selected mode of the first air path 30 and the second air path 40 is in the communication state, and the other air path is in the non-communication state. Thus, the air path corresponding to the mode selected by the switching means 57 can be reliably communicated.

When the apparatus is operating under one of the vacuum cleaner mode and the air purifier mode switched by the switching means 57, it is determined based on switching to the other mode by the switching means 57. Since the electric blower 60 is stopped, when the mode is switched to the other mode during the operation of the one mode, the user can surely recognize this and return the erroneous operation to an appropriate operation to reliably prevent the erroneous use. It can be prevented.

Further, when the valves 52 and 53 do not communicate or close the first air passage 30 and the second air passage 40, the electric blower 60 is connected to the first valve 52 and the second valve 53.
Therefore, the respective valves in the non-communication state can stably and surely maintain the non-communication state sucked by the negative pressure generated by the electric blower 60.

Further, since the deodorant storage section for storing the volatile deodorant 100 is formed downstream of the blower chamber 20, the unpleasant odor and the like in the room can be deodorized. A storage chamber 92 having an opening 93 and an opening / closing lid 9 for opening and closing the opening 93
5 and the open / close lid 95 is opened when the electric blower 60 is in operation and closed when the electric blower 60 is not in operation, so that consumption of the deodorant 100 can be prevented.

Note that in the first embodiment,
The switching of the switching means 57 is configured such that the operating piece 57c provided on the rotating shaft 55 of the operating knob 56 is operated to operate the operating knob 56 to selectively oppose the photo interrupters 57a and 57b. A switch means for selecting the cleaner mode and the air cleaner mode may be provided at the upper part of the cleaner body A, respectively, and may be selectively switched by a closing signal of the switch means. Also,
In such a configuration, a method of operating the valve means 50 in conjunction with the mode switching is such that, for example, the rotation axis of the valve means 50 is rotated by a stepping motor or an electromagnet, and the stepping motor is switched to the mode switching mode. What is necessary is just to drive by the closing signal of a switch means.

Next, the second aspect of the present invention in consideration of these points will be described.
Will be described with reference to FIGS. The second embodiment is different from the first embodiment in that the mode selection and the air path switching can be easily performed with one touch, and a large load due to the suction airflow is not applied to the air path switching valve means. Unlike the embodiment, the other configurations are the same as those of the first embodiment including the portions not shown in FIGS.
It has the same or similar configuration as the vacuum cleaner with an air cleaning function according to the embodiment. Therefore, components not shown are substituted with FIGS. 1 to 5, and the same or similar components shown are given the same reference numerals as those in the first embodiment, and the description of those components and the description thereof will be omitted. Although the description of the operation and effect based on this is omitted, these same or similar components also constitute a part of the configuration of the vacuum cleaner with the air cleaning function according to the second embodiment.

In the second embodiment, as shown in FIG. 6, a mode selection switch S4 is mounted on the upper case 2 of the main body case 1 side by side with the power switch S1. The switch S4 is, for example, a push-type changeover switch having a push knob which is repeatedly pushed in between the non-push position and the push position, and selects the cleaner mode when the push knob is in the non-push position. The air purifier mode is selected when the air purifier is at the pushing position. A switch signal accompanying the selection of the position of the pressing knob of the switch S4 is supplied to the control means 210 shown in FIG.

Note that the mode selection switch S4 is
b may be provided on the operation unit 14c, but when provided on the cleaner main body A as shown in FIG. 6, when operating the hand-operated switch S2 and the control switch S3 which are frequently operated during use, a mode selection is performed. This is advantageous in that the switch S4 is not erroneously operated, and inadvertent mode switching can be prevented.

As shown in FIGS. 7 and 8, an electric switching mechanism 257 that is operated by being energized is connected to the rotating shaft 54 of the valve means 50 as switching means. For example, a rotary solenoid or the like is employed as the switching mechanism. The solenoid has a first position and a second position.
The rotary shaft 54 is reciprocally rotated over the position (the rotation angle is an angle obtained by subtracting the included angle A from the included angle B). One position is held by a spring included in the solenoid, and the other is held. Is held by the exciting force of the solenoid.

Note that instead of the rotary solenoid, the first
A plunger reciprocating between a position and a second position and a plunger-type solenoid having a spring for urging the plunger are employed, and a tip portion of the plunger is formed in a rack structure, and this portion is provided on a rotating shaft 54 with a pinion portion. And an electric switching mechanism that converts the linear motion of the solenoid into the reciprocating rotation of the rotary shaft 54 to rotate the valve means 50 may be employed. Furthermore, an electric switching mechanism may be employed, such as a stepping motor that can rotate forward and reverse and restrict the rotation to a predetermined angle.

Further, as shown in FIG.
The motor-driven switching means 257 made up of a rotary solenoid is connected to 10 via a solenoid drive circuit 211. The switching means 257 is controlled by the control means 210 as shown in the flowchart of FIG.
In the control, when the mode selection switch S4 is operated during the operation of the electric blower 60, the switch input is invalidated.

Further, photo interrupters 57a and 57b (not shown) and an operating piece 57c not shown in this embodiment
(Refer to FIG. 4 of the first embodiment)
Position detecting means 157 (FIG. 9) for detecting the rotational position of
Has been recognized as. The configuration other than the above is the same as that of the first embodiment.

Next, the control means 2 based on the operation of the switching means
The control operation of No. 10 will be described with reference to FIG. When the power switch S1 is turned on, the control means 210 executes step 1 to determine whether or not the switch S4 has been operated based on the switch signal supplied from the mode selection switch S4. If this determination is YES, the control means 210 proceeds to step 2 and performs a process of turning on / off the electric switching mechanism 257 made of a rotary solenoid. This processing is executed via the solenoid drive circuit 211, whereby the valve means 50 is rotated clockwise or counterclockwise when the solenoid is energized. Next, proceeding to step 3, it is determined whether or not the operating piece 57c of the switching means 57 faces the photo interrupter 57a or 57b, that is, whether or not the position detection of the valve means 50 has been input. If this determination is YES, the control means 210 proceeds to step 4 and proceeds to step S4.
0 is an operation standby state.

Thereafter, the process proceeds to step 5 where the control means 21
0 determines whether or not the hand operation switch S2 has been turned on. If the determination is YES, the control means 210 proceeds to step 6 to energize the electric blower 60 and operate the vacuum cleaner. In the next step 7, the control means 210 controls the electric blower 6 based on the input from the drive state detecting means 112.
It is determined whether 0 is in operation. This judgment is Y
When ES is reached, the control means 210 proceeds to step 8 and determines whether or not the mode selection switch S4 has been operated.

If this determination is YES, the control means 210
Performs a process of canceling the switch signal from the mode selection switch S4 operated in step 9 to the control means 210. In other words, during operation of the electric blower 60 (during operation in the vacuum cleaner mode or the air purifier mode), regardless of the switch signal by operating the mode selection switch S4, control according to this switch signal is performed by the control unit 21.
0 is not set, and the operation in one of the modes, which is the operation state before the switch S4 is operated, is continued. If the determination in step 8 is NO, the process returns to step 7 to determine whether or not the electric blower 60 is operating.

After the step 9, the control means 2
10 proceeds to step 10 to determine whether or not the power switch S1 has been turned off. If the determination is YES, step 11 is executed to perform processing for turning off the electric blower 60. If the determination in step 10 is NO, the process returns to step 7 to determine whether or not the electric blower 60 is operating.

Therefore, in the vacuum cleaner with an air cleaning function according to the second embodiment having the above-described configuration, the desired mode is selected by operating the mode selection switch S4, and the electric switching mechanism 257 is operated. Is supplied to the switching means, and the operation of the means 257 automatically switches the air path corresponding to the selected mode. As described above, the mode switching and the air path switching can be realized by a one-touch operation of the mode selection switch s4, so that it can be used easily.

Further, during operation in the vacuum cleaner mode or the air purifier mode, the electric blower 60 is operating, and the suction airflow generated by the operation is supplied to the valve 52 or the valve 53 located at the position of the valve means 50 in the air path cutoff position. Therefore, when the mode selector switch S4 is erroneously operated during the operation of the electric blower 60 and the valve means 50 performs an air path switching operation, the valve means 50 performs the operation of the suction airflow. Since the valve means 50 is moved against the wind pressure, a large load is applied to the valve means 50, and there is a possibility that the valve 52 or the valve 53, a portion supporting the rotating shaft, and the like may be damaged.

However, in the second embodiment,
If the mode selection switch S4 is erroneously operated during the operation of the electric blower 60, the switch input is invalidated by the control function of the control means 210 as shown in the flowchart of FIG. Therefore, during operation in one mode, it is not possible to select an undesired other mode and switch the air path, so that a large load is not received based on the fact that the valve means 50 and the like operate against the suction airflow. , To prevent the damage.

In the above-mentioned embodiments, the valve means 50 is constituted by integrally mounting two thin-walled valves 52 and 53 on the support shaft 51, and these valves 52 and 53 are provided in the blower chamber 20. Although the intake ports 23a and 24a respectively formed in the inclined walls 23 and 24 are opened and closed, the first air path 30 and the second air path 40 are configured to be connected or disconnected.
Instead of this, for example, as shown in FIG.

The configuration other than the points described below is similar to that of FIG.
The configuration is the same as or similar to that of the vacuum cleaner with an air purifying function according to the first embodiment, including portions not shown. Therefore, components not shown are substituted with FIGS. 1 to 5, and the same or similar components shown are given the same reference numerals as those in the first embodiment, and the description of those components and the description thereof will be omitted. Although the description of the operation and effect based on this is omitted, these same or similar components also constitute a part of the configuration of the vacuum cleaner with the air cleaning function according to the third embodiment.

As shown in FIG. 11, the hanging ports 123 and 124 are provided below the blower chamber 20 and the lower case 3 is provided with locking walls 123b and 124b opposed to the hanging walls 123 and 124, respectively. 123
a and 124a are formed, and valves 152 and 153 which are located outside the hanging walls 123 and 124 and are integrally attached to the rotating shafts 154 and 155, respectively, are rotatably provided, and the electric blower is operated by the valves 152 and 153. 60 intake side and 1st
The air passage 30 and the second air passage 40 are respectively
The suction port 5 may be configured to be in communication or non-communication. In this case as well, seal members 126a and 126b for maintaining airtightness are provided on the hanging walls 123 and 124 and the locking walls 123b and 124b. In this case, the valve means is constituted by the valve 152 and the valve 153. In this case, the interlocking of the switching means and the valve means is performed by cleaning the switching means at the upper portion of the cleaner body A as described above. Switch means for selecting the air purifier mode and the air purifier mode. The switch means is selectively switched by a closing signal of the switch means, and is rotated by a stepping motor or an electromagnet operated by the closing signal of the switch means. The driving shafts 154 and 155 may be rotated. And also in this case, the valves 152 and 1
When a negative pressure generated by the electric blower 60 is applied to the 53, the non-communication state can be stably and reliably maintained because the hanging walls 123, 124 and the locking walls 123b, 124b as the regulating portions are pressed.

In each of the above embodiments, the opening and closing lid 95 for opening and closing the opening 93 of the storage chamber 92 is opened and closed by the wind pressure of the exhaust air. For example, an electromagnet is used. Power switch S1 or S2
May be opened and closed in conjunction with the closing or opening of the. In this case, there is an advantage that the closed state between the opening 93 and the opening / closing lid 95 can be ensured.
