Embodiment 1 FIG.
FIG. 1 is an external perspective view of a vacuum cleaner 100 according to Embodiment 1 of the present invention. In FIG. 1, one end side of a hose 2 is connected to the front side of the main body 1 of the vacuum cleaner 100, and the other end side of the hose 2 is connected to an operation unit 3 for performing various operation inputs. The operation unit 3 is detachably connected to the extension tube 4, and the distal end of the extension tube 4 is detachably connected to the suction tool 5.

  A power cord 6 wound around a cord reel (not shown) inside the main body 1 can be drawn out from the back side of the main body 1. A power plug 7 for connecting to an outlet provided on a wall or the like is provided at the tip of the power cord 6.

  On the upper surface side of the main body 1, notification means 8 for notifying the user of information is provided. In the first embodiment, as the notification means 8, a light notification unit 8a that visually notifies by light, such as an LED (Light Emitting Diode) lamp, and a voice notification unit 8b that performs auditory notification by sound or buzzer sound, It has. The light notification unit 8a turns on or blinks light to visually notify the user with light. The voice notification unit 8b performs notification by a buzzer sound, a melody sound, an arbitrary voice message, or other voice. Hereinafter, the light notification unit 8a and the voice notification unit 8b may be collectively referred to as the notification unit 8.

  The main body 1 of the vacuum cleaner 100 includes an electric blower 9 that generates suction force and a dust collection chamber (not shown) that collects dust sucked by the electric blower 9.

  FIG. 2 is a schematic diagram of a main part of the operation unit 3. The operation unit 3 includes a power switch 31 and a timer setting switch 32. The power switch 31 sets the ON / OFF operation of the electric blower 9 and stops the notification by the notification unit 8 when pressed when the notification unit 8 is operating. The timer setting switch 32 is a slide type switch, and sets a predetermined time T1 (details will be described later) until the notification means 8 starts notification. The power switch 31 and the timer setting switch 32 may be any ones that can realize an equivalent function.

  FIG. 3 is a functional block diagram of the main body 1 according to Embodiment 1 of the present invention. In FIG. 3, a commercial power source 22, a resistor 21, an electric blower 9, a current detection unit 23, and a power switch 31 are provided. The current detection means 23 includes a current sensor and detects a current flowing through the main body 1.

The microcomputer 10 includes a control unit 101 and a timer 102. The timer 102 measures the time when the current detection unit 23 detects the current, that is, the time during which the main body 1 is energized, based on the instruction of the control unit 101. The control unit 101 acquires the predetermined time T1 set by the timer setting switch 32, and controls the notification unit 8 to perform notification when the measurement time by the timer 102 reaches the predetermined time T1. Then, when an input to the power switch 31 is performed during the notification, the control unit 101 controls to stop the notification by the notification unit 8.

  FIG. 4 is a timing chart showing the relationship between the state of the vacuum cleaner 100 and the time measurement timing of the timer 102. As the state of the vacuum cleaner 100, the power plug 7 is disconnected from the outlet and the main body 1 is not energized, “the power plug 7 is detached”, the power plug 7 is inserted into the outlet and the main body 1 is energized, In addition, “power switch 31 OFF / power plug 7 connection”, which is a state where the power supply switch is OFF and the electric blower 9 is not energized, and “power supply” which is a state where the electric blower 9 is energized while the power switch is ON. There is a state of “switch ON”. In FIG. 4, a typical scene when the user uses the vacuum cleaner 100 will be described as an example. In the first embodiment, the measurement time by the timer 102 is represented as a measurement time t, and may be distinguished from t11, t12, t13, etc. for explanation.

In FIG. 4, when the power plug 7 is inserted, that is, when energization of the main body 1 is started, the timer 102 starts measurement and the time until the power switch 31 is turned on (when cleaning is started). t11 is measured. Here, it can be said that the time of the state in which the power switch 31 is not turned on (without starting cleaning) after the power plug 7 is inserted is measured.
Then, the measurement starts again when the power switch 31 is turned off, and the time t12 until the power switch 31 is turned on next (when cleaning is resumed) is measured. Here, it can be said that the time of the state in which the cleaning is interrupted and the power plug 7 is kept inserted is measured.
Further, measurement is started when the power switch 31 is turned off, and a time t13 until the power plug 7 is removed is measured. Here, it can be said that the time when the power plug 7 is kept plugged in after cleaning is measured.

  Thus, the timer 102 measures the time during which the power switch 31 is in the OFF state from when the power plug 7 is inserted into the outlet until it is removed (while the main body 1 is energized). . In other words, the time for which the power plug 7 is left plugged without cleaning is measured. The trigger for starting the measurement of the timer 102 is the connection of the power plug 7 or the ON of the power switch 31, and the trigger for the end of the measurement of the timer 102 is the OFF of the power switch 31 or the disconnection of the power plug 7.

  FIG. 5 is an operation flow relating to time measurement by the timer 102 and notification by the notification means 8. It is assumed that the predetermined time T1, which is the time until the notification means 8 starts notification, is set in advance by the timer setting switch 32 described above. Hereinafter, based on the main action pattern when the user uses the vacuum cleaner 100, the time measurement of the timer 102 and the notification operation of the notification means 8 will be described based on FIG. In FIG. 5, in order to pay attention to the time measurement by the timer 102, the corresponding portions are shaded.

First, the operation when the power plug 7 is connected and cleaning is started within the predetermined time T1 (the power switch 31 is turned on) will be described.
When the power plug 7 is connected (S201), the timer 102 starts measuring the measurement time t (S202). When the power switch 31 is turned on in the state where the measurement time t has not reached the predetermined time T1 (S203) (S204), the timer 102 ends the time measurement (S206). And since the electric blower 9 act | operates when the power switch 31 is turned ON (S207), the user can clean. When the power switch 31 is turned off (S208), the electric blower 9 stops (S210). Subsequently, the timer 102 starts measuring the measurement time t (S202). In addition, when the power supply plug 7 is removed from the outlet while the electric blower 9 is operating (S207) (S208), the electric blower 9 is stopped (S209). In the series of flows described here, since the measurement time t (the time from when the power plug 7 is connected to when cleaning is started) is shorter than the predetermined time T1, the notification by the notification means 8 is not performed. Note that when the power plug 7 is removed in step S204, the measurement by the timer 102 ends (S205).

Next, an operation when the power plug 7 is connected but cleaning is not started within the predetermined time T1 (the power switch 31 is in the OFF state) will be described.
When the power plug 7 is connected (S201), the timer 102 starts measuring the measurement time t (S202). While the measurement time t does not exceed the predetermined time T1, steps S203 and S204 are repeated. When the measurement time t exceeds the predetermined time T1 (S203), the notification unit 8 starts notification (S211). When the user turns on the power switch 31 having a function of stopping the notification (S212), the timer 102 ends the measurement (S214), and the notification by the notification means 8 stops (S215). And since the electric blower 9 act | operates when the power switch 31 is turned ON (S207), the user can clean. The subsequent operation is as described above. In the series of flows described here, since the measurement time t (the time from when the power plug 7 is connected to when cleaning is started) exceeds the predetermined time T1, the notification by the notification means 8 is performed. Therefore, it is possible to notify the user that the power plug 7 is still connected, and to prompt the user to take appropriate actions such as restarting cleaning.

Next, after the cleaning is completed (after the power switch 31 is turned off), the operation when the predetermined time T1 has passed with the power plug 7 being inserted will be described. Here, the operation after step S207 will be described.
When the electric blower 9 is operating (S207) and the power switch 31 is turned off (S208), the electric blower 9 stops operating (S210). While the electric blower 9 is operating, measurement by the timer 102 is not performed (see S206 and S214), but when the electric blower 9 is stopped, the timer 102 starts measuring time again (S202). And if the measurement time t exceeds predetermined time T1 (S203), the alerting | reporting means 8 will start alerting | reporting (S211). When the user disconnects the power plug 7 from the outlet (S212), the timer 102 ends the time measurement (S213). In addition, when the power supply of the notification means 8 is the same as the power supply of the main body 1, the operation of the notification means 8 is also stopped by removing the power plug 7. In the series of flows described here, since the measurement time t (the time since the electric blower 9 was stopped) exceeded the predetermined time T1, notification by the notification means 8 was performed. Therefore, it is possible to notify the user that the power plug 7 is still inserted after cleaning, and to prompt the user to take an appropriate action such as removing the power plug 7.

  By the way, as described above, the notification means 8 performs notification until it is stopped by the operation of the power switch 31, but for a while after the notification is started, notification is performed by both the light notification unit 8a and the voice notification unit 8b. After the elapse of time, the notification by the voice notification unit 8b may be automatically stopped and only the notification by the light notification unit 8a may be performed. In this way, for example, even when there is a visitor or a telephone during cleaning and the cleaning is temporarily interrupted, it is possible to continue notification to the user, reduce noise and reduce voice. The power consumption accompanying the notification can be reduced.

  As described above, in the first embodiment, the measurement time t is the time when the main body 1 is energized and the power switch 31 is not turned on, that is, the time when the power plug 7 is not being cleaned. Since the measurement is performed and the notification is performed when the measurement time t exceeds the preset predetermined time T1, it is possible to notify the user that the power plug 7 is still connected. Therefore, wasteful power consumption can be suppressed, and inconveniences such as catching on the power cord 6 can be avoided. In the first embodiment, the power plug 7 is kept plugged in before cleaning, the cleaning is interrupted and the power plug 7 is kept plugged, and the power plug 7 is removed after cleaning. Since it is possible to measure the time for which the plug is left plugged, it is possible to prevent the power plug 7 from being left plugged through a series of operations when the vacuum cleaner 100 is used. In addition, since the power switch 31 is provided with a function for stopping the notification of the notification means 8, it is not necessary to separately provide a switch for stopping the notification means 8, and the operation unit 3 can be configured simply.

Embodiment 2. FIG.
In the first embodiment described above, an example has been described in which the time during which cleaning is not performed while the power plug 7 is connected is measured. In the second embodiment, an example will be described in which notification is given to the user when the time since the connection of the power plug 7 exceeds a predetermined time regardless of whether or not cleaning is started. . In addition, since the basic structure of the vacuum cleaner 100 is the same as that of the above-mentioned Embodiment 1, it demonstrates centering on the measurement timing by the timer 102, and alerting | reporting operation | movement.

  FIG. 6 is a timing chart showing the relationship between the state of the vacuum cleaner 100 and the measurement timing by the timer 102. In FIG. 6, a typical scene when the user uses the vacuum cleaner 100 will be described as an example. In the second embodiment, the measurement time by the timer 102 is expressed as measurement time t, and may be distinguished from t21, t22, and the like for explanation. Moreover, the predetermined time until the notification means 8 performs notification is represented as a predetermined time T2.

  In FIG. 6, when the power plug 7 is inserted, that is, when energization of the main body 1 is started, the timer 102 starts measurement. When the measurement time t21 exceeds the predetermined time T2, the notification unit 8 starts notification, but when the notification by the notification unit 8 is stopped, the timer 102 resets the measurement and measures the time t22 again. The measurement is continued until the power plug 7 is removed from the outlet. That is, the timer 102 continues to measure time while resetting every time the notification by the notification means 8 is stopped until the power plug 7 is connected and disconnected. Moreover, every time the measurement time t reaches the predetermined time T2, the notification by the notification means 8 is performed.

  FIG. 7 is an operation flow relating to time measurement by the timer 102 and notification by the notification means 8. It is assumed that the predetermined time T2, which is the time until the notification means 8 starts notification, is set in advance by the timer setting switch 32 described above. Hereinafter, based on FIG. 7, operation | movement is demonstrated along the main action pattern at the time of a user using the vacuum cleaner 100. FIG.

First, a case where a series of operations from connecting the power plug 7 to disconnecting the power plug 7 from the outlet is performed within a predetermined time T2 will be described.
When the power plug 7 is connected (S301), the timer 102 starts measuring the measurement time t (S302). When the power switch 31 is turned on (S304) in a state where the measurement time t has not reached the predetermined time T2 (S303), the electric blower 9 starts operating (S306), and the user can perform cleaning.
Then, if the power switch 31 is turned off in a state where the measurement time t has not reached the predetermined time T2 (S307) (S308), the electric blower 9 is stopped (S311), and the process returns to step S303. Even at this stage, if the measurement time t has not reached the predetermined time T2 (S303), the power plug 7 is removed from the outlet (S304), and the timer measurement is terminated (S305). Alternatively, even if the power plug 7 is disconnected from the outlet (S308) when the measurement time t has not reached the predetermined time T2 (S307), the timer 102 ends the measurement (S309), and the electric blower 9 stops operating. To do. In the series of flows described here, since the measurement time t, which is the time from when the power plug 7 is connected to when it is disconnected, is shorter than the predetermined time T2, the notification by the notification means 8 is not performed.

Next, a case where the measurement time of the timer 102 reaches the predetermined time T2 during cleaning is described.
When the power plug 7 is connected (S301), the timer 102 starts measuring (S302), and the power switch 31 is turned on (S304) in a state where the predetermined time T2 has not elapsed (S303), the electric blower 9 is activated ( S306) and cleaning can be started. While the predetermined time T2 has not elapsed after the start of cleaning (S307), the notification unit 8 does not perform notification.
When the predetermined time T2 is reached during cleaning (S307), the notification means 8 starts notification (S312). When the user turns off the power switch 31 having the function of stopping the notification (S313), the measurement time t of the timer 102 is reset (S315), the notification by the notification means 8 is stopped (S316), and the electric blower 9 is also used. Stop (S311). In the series of flows described here, since the predetermined time T2 has elapsed since the power plug 7 was connected during cleaning, the user was notified. Therefore, the user can be informed that the predetermined time T2 has elapsed since the power plug 7 was connected, including during cleaning.

Next, the case where the measurement time of the timer 102 reaches the predetermined time T2 in a state where the cleaning is interrupted and the power plug 7 is kept inserted will be described.
When cleaning is interrupted, that is, after the electric blower 9 is stopped in step S311, the process returns to step S303. Here, when the predetermined time T2 elapses (S303), the notification unit 8 is activated (S317). When the user turns on the power switch 31 (S318), the notification unit 8 stops (S320). Here, after the timer 102 is reset (S321), measurement of the measurement time t continues. And since the electric blower 9 operates (S306), the user can perform cleaning. In the series of flows described here, since the predetermined time T2 has passed with the cleaning interrupted and the power plug 7 still connected, the user is notified. Therefore, it is possible to notify the user that the power plug 7 is still connected, and to prompt the user to take appropriate actions such as restarting cleaning.

Next, the case where the measurement time of the timer 102 has reached the predetermined time T2 with the power plug 7 still inserted after cleaning will be described.
After cleaning, that is, after the electric blower 9 is stopped in step S311, the process returns to step S303. Here, when the predetermined time T2 elapses (S303), the notification unit 8 is activated (S317). When the user removes the power plug 7 from the outlet (S318), the timer measurement is finished (S319), and the notification means 8 is also stopped. When the notification means 8 is operating (S312), when the power plug 7 is removed from the outlet (S313), the timer 102 ends the measurement (S314). In the series of flows described here, the user is notified because the predetermined time T2 has elapsed with the power plug 7 still connected after cleaning. Therefore, it is possible to notify the user that the power plug 7 is still inserted after cleaning, and to prompt the user to take an appropriate action such as removing the power plug 7.

  As shown in FIGS. 6 and 7, in the second embodiment, measurement by the timer 102 is started when the power plug 7 is connected, and measurement by the timer 102 is performed when the power plug 7 is disconnected from the outlet. finish. When the measurement time t reaches the predetermined time T2, notification by the notification means 8 is performed, and when the notification is stopped, the timer 102 is reset. That is, when the power plug 7 is connected, the timer 102 measures the measurement time t regardless of whether or not cleaning is started, and notifies when the measurement time t reaches the predetermined time t2. Then, after stopping the notification, the timer 102 is reset and then time measurement is continued. When the predetermined time t2 is reached again, the notification is performed.

  As described above, in the second embodiment, the time from when the power source is energized to the main body 1 is measured as the measurement time t, and the notification is performed when the measurement time t exceeds a preset predetermined time T2. As a result, the user can be informed of the state in which the power plug 7 remains plugged. Therefore, wasteful power consumption can be suppressed and inconveniences such as catching on the power cord 6 can be solved. In the second embodiment, unlike the first embodiment, the time measurement is continuously performed regardless of whether the cleaning is started (whether the power switch 31 is turned on). Therefore, even when the user is cleaning, the user is notified when the predetermined time T2 elapses after the power plug 7 is connected. Therefore, it is possible to notify the user that the predetermined time T2 has elapsed, and to allow the user to recognize that the state in which the power plug 7 is connected is longer than the preset time T2.

Embodiment 3 FIG.
In the third embodiment, the power plug 7 is not connected to perform cleaning (the power switch 31 is OFF), and the electric blower 9 is energized (the power switch 31 is ON). An example in which the time is measured and notification is performed when each time exceeds a predetermined time will be described. That is, in the third embodiment, the user is informed that the power plug 7 is still inserted, and the user is also notified when the continuous energization time of the electric blower 9 exceeds a predetermined time. Do. In addition, since the basic structure of the vacuum cleaner 100 is the same as that of the above-mentioned Embodiment 1, it demonstrates centering on the measurement timing by the timer 102, and alerting | reporting operation | movement.

  FIG. 8 is a timing chart showing the relationship between the state of the vacuum cleaner 100 and the measurement timing by the timer 102. In FIG. 8, a typical scene when the user uses the vacuum cleaner 100 will be described as an example. In the third embodiment, the measurement time by the timer 102 is expressed as a measurement time t, and may be described separately from t31, t32, t33, t34, etc. for explanation. Further, a predetermined time until notification of a state in which the power plug 7 is kept plugged is expressed as a first predetermined time T3, and a predetermined time until notification regarding the continuous energization time of the electric blower 9 is expressed as a second predetermined time T4. .

In FIG. 8, when the power plug 7 is inserted, that is, when energization of the main body 1 is started, the timer 102 starts measurement and measures the time t31 until the power switch 31 is turned on. The time t31 measured here can be said to be the time from when the power plug 7 is connected to when cleaning is started.
When the power switch 31 is turned on, the measurement by the timer 102 is once stopped and then the measurement is started again, and the time t32 until the power switch 31 is turned off is measured. The time t32 measured here is the energization time to the electric blower 9.
When the power switch 31 is turned off, the measurement by the timer 102 is once stopped and then the measurement is started again, and the time t33 until the power switch 31 is turned on is measured. The time t33 measured here can be said to be a time during which cleaning is interrupted while the power plug 7 is inserted.
When the power switch 31 is turned off, the measurement by the timer 102 is once stopped and then the measurement is started again, and the time t34 until the power plug 7 is removed from the outlet is measured. It can be said that the time t34 measured here is the time that the power plug 7 is left inserted after the cleaning is finished.

  Thus, the timer 102 measures the time (t31, t33, t34) when the power plug 7 is inserted into the outlet but is not cleaned, and the time (t32) when the electric blower 9 is energized. . The trigger for starting the measurement of the timer 102 is the connection of the power plug 7, the ON of the power switch 31, and the OFF of the power switch 31. The trigger of the end of the measurement of the timer 102 is the ON of the power switch 31, the OFF of the power switch 31, and the power plug 7 withdrawal.

  FIG. 9 is an operation flow relating to time measurement by the timer 102 and notification by the notification means 8. It is assumed that the first predetermined time T3 and the second predetermined time T4 are previously set by the timer setting switch 32 described above. The setting means for the first predetermined time T3 and the second predetermined time T4 may be shared by the timer setting switch 32, but a setting switch may be provided separately. Hereinafter, based on FIG. 9, operation | movement is demonstrated along the main action pattern at the time of a user using the vacuum cleaner 100. FIG.

First, the operation when the power plug 7 is connected and cleaning is started within the predetermined time T3 (the power switch 31 is turned on) will be described.
When the power plug 7 is connected (S401), the timer 102 starts measuring the measurement time t (S402). The measurement time t measured here is the time when the power plug 7 is connected but not cleaned (hereinafter referred to as main body energization time t in the third embodiment). As long as the main unit energization time t does not reach the first predetermined time T3 (S403), no notification is made even if the power switch 31 is kept in the OFF state (S404). If the power plug 7 is removed from the outlet in step S404, the timer 102 ends the measurement (S405). Also, when the power switch 31 is turned on in step S404, the timer 102 ends the measurement (S406), and the electric blower 9 starts operating (S407), so that the user can perform cleaning. In the series of flows described here, since the cleaning is started within the first predetermined time T3 after the power plug 7 is connected or the power plug 7 is disconnected from the outlet, the notification by the notification means 8 is performed. Not.

Next, the operation when the power plug 7 is connected but cleaning is not started within the first predetermined time T3 (the power switch 31 is in the OFF state) will be described.
When the power plug 7 is connected (S401), the timer 102 starts measuring the main body energization time t (S402). When the measurement time t reaches the predetermined time T3 (S403), the notification unit 8 starts notification (S420). Then, when the power switch 31 having the function of stopping the notification is turned on (S421), the timer 102 ends the measurement (S423), and the notification means 8 also stops (S424). Note that the timer 102 also ends the measurement (S422) when the power plug 7 is disconnected from the outlet (S421) while the notification means 8 is operating (S420). In the series of flows described here, since the first predetermined time T3 has passed without the cleaning being performed after the power plug 7 is connected, the notification by the notification means 8 is performed. Therefore, it is possible to notify the user that the power plug 7 is still inserted, and to prompt the user to take appropriate actions such as starting cleaning.

Next, the operation when the cleaning is started (the energization of the electric blower 9 is started) and the cleaning is finished within the second predetermined time T4 (the energization of the electric blower 9 is stopped) will be described. . Here, the operation after step S407 will be described.
When the electric blower 9 starts operating (S407), the timer 102 starts measuring time t (S408). Here, the time t measured by the timer 102 is the energization time to the electric blower 9 (hereinafter referred to as the electric blower energization time t in the third embodiment). While the electric blower energization time t does not reach the second predetermined time T4 (S409), no notification is given even if the power switch 31 is kept on (S410). When the power plug 7 is removed from the outlet in step S410, the timer 102 ends the measurement (S411) and the electric blower 9 is also stopped. Also, when the power switch 31 is turned off in step S410, the timer 102 ends the measurement (S413), and the electric blower 9 also stops (S414). In the series of flows described here, since the continuous energization time to the electric blower 9 does not exceed the second predetermined time T4, the notification by the notification unit 8 is not performed.

Next, an operation when the second predetermined time T4 has elapsed from when cleaning is started (after energization of the electric blower 9 is started) to when cleaning is completed will be described. Here, the operation after step S407 will be described.
When the electric blower 9 starts operating (S407), the timer 102 starts measuring time t (S408). Here, the time t measured by the timer 102 is the electric fan energization time t. When the electric blower energization time t reaches the second predetermined time T4 (S409), the notification unit 8 starts notification (S415). When the user turns off the power switch 31 having the function of stopping the notification (S416), the timer 102 ends the measurement of the electric blower energization time t (S418), the notification means 8 stops (S419), and the electric motor The blower 9 is also stopped (S414). In the series of flows described here, since the continuous energization time to the electric blower 9 exceeded the second predetermined time T4, the user was notified. Therefore, the user can recognize that the cleaning is longer than the preset second predetermined time T4. Further, when the user forgets to turn off the power switch 31, an appropriate action such as turning off the power switch 31 can be urged by notifying by the notification means 8.

  As described with reference to FIGS. 8 and 9, in the third embodiment, the main body is the time when the power plug 7 is connected and the cleaning is not performed (the electric blower 9 is not energized). The energization time t is measured, and if this exceeds the first predetermined time T3, the user is notified. In addition, after the electric blower 9 starts operating, the electric blower energization time t is measured as the energization time to the electric blower 9, and when this exceeds the second predetermined time T4, the user is notified.

As described above, in the third embodiment, the notification is performed when the time when the power plug 7 is connected and the cleaning is not performed exceeds the first predetermined time T3. For this reason, when cleaning is interrupted before starting cleaning, after the cleaning is finished, it is possible to prevent the power plug 7 from being left and to prevent unnecessary power consumption. Inconveniences such as catching a foot on the power cord 6 can be avoided.
Further, when the continuous energization time when the electric blower 9 is operating exceeds the second predetermined time T4, notification is performed. For this reason, when the user forgets to turn off the power switch 31, the user can appropriately turn off the power switch 31. Moreover, since the useless driving | operation of the electric blower 9 can be prevented, the lifetime of the electric blower 9 can be prevented from being shortened. In particular, even if the user is difficult to hear the operation sound of the vacuum cleaner 100 such as in a noisy environment, the notification means 8 includes the light notification unit 8a and provides visual notification. Notification can be performed appropriately.
In addition, both the time when the power plug 7 is connected and cleaning is not performed (main body energization time t) and the continuous energization time of the electric blower 9 (electric blower energization time t) are both measured by the timer 102. Therefore, it is not necessary to provide a separate timer, and the microcomputer 10 can have a simple configuration.

  In the third embodiment, when the power plug 7 is not connected and the cleaning is not performed exceeds the first predetermined time T3, the time during which the electric blower 9 is energized is the second predetermined time. You may change the alerting | reporting method by the alerting | reporting means 8 by the case where it exceeds T4. For example, the color of the light emitted from the light notification unit 8a may be changed, or one of the lights may be blinked and the other lighted. Also, the buzzer sound or voice message emitted by the voice notification unit 8b may be different. By doing in this way, a user can be made to recognize correctly whether it is information about the fact that the power plug 7 is kept inserted, or information about continuous operation to the electric blower 9.

  In the third embodiment, when the time during which the electric blower 9 is energized exceeds the second predetermined time T4, the power switch 31 is not automatically notified by the notification means 8, but the power switch 31 is automatically switched on. It is good also as stopping electricity supply to the electric blower 9 by turning off. By doing in this way, even when the user forgets to turn off the power switch 31 and goes out, the electric blower 9 can be prevented from being wasted, so the life of the electric blower 9 can be shortened. In addition to preventing this, wasteful power consumption can be suppressed. Further, when the time during which the electric blower 9 is energized exceeds the second predetermined time T4, the notification means 8 gives notification, and when the predetermined time has passed without this notification being stopped, the power switch 31 is automatically set. May be turned off. Furthermore, when the time during which the electric blower 9 is energized exceeds the second predetermined time T4, the user may be able to select whether to perform notification by the notification means 8 or to turn off the power switch 31. . By doing in this way, useless continuous operation of the electric blower 9 can be prevented by a method convenient for the user, and usability can be improved.

Embodiment 4 FIG.
In the first to third embodiments described above, the predetermined times T1 to T4 are set in advance by the timer setting switch 32. In the fourth embodiment, a case where the predetermined times T1 to T4 are automatically set based on the usage state of the electric vacuum cleaner 100 will be described. In the fourth embodiment, a case where the present invention is applied to the above-described third embodiment will be described as an example.

  FIG. 10 is a functional block diagram of the vacuum cleaner 100 according to Embodiment 4 of the present invention. FIG. 10 is characterized in that a storage unit 103 and a writing unit 104 are provided, and the timer setting switch 32 is not provided. The writing unit 104 writes the time measured by the timer 102 to the storage unit 103. The storage means 103 is a non-volatile memory, and can store the time measured by the timer 102 for a predetermined number of times. In addition, the same code | symbol is attached | subjected about the component similar to the vacuum cleaner 100 demonstrated in above-mentioned Embodiment 1. FIG.

  In the fourth embodiment, as described in the third embodiment, the timer 102 is in a state in which the power plug 7 is connected but is not cleaned (the power plug 7 is left plugged in). Is measured as a measurement time t (hereinafter referred to as main body energization time t41 in the fourth embodiment), and a continuous energization time of electric blower 9 is also measured as measurement time t (hereinafter referred to as electric blower energization time t42). . Then, the writing means 104 writes the main body energization time t41 and the electric blower energization time t42 in the storage means 103 at each timing when the measurement is finished.

  FIG. 11 is a configuration diagram of the storage unit 103. The storage means 103 stores the main body energization time t41 for n times, and stores the electric blower energization time t42 for m times. The number of times n for storing the main body energization time t41 and the number of times m for storing the electric fan energization time t42 may be the same or different.

  And the control means 101a calculates | requires the average value for n times of main body energization time t41, and makes this 1st predetermined time T3. Moreover, the average value for m times of the electric blower energization time t42 is obtained, and this is set as the second predetermined time T4. As described in the third embodiment, when the main body energization time t41 reaches the first predetermined time T3, or when the electric blower energization time t42 reaches the second predetermined time T4, the notification means 8 Notification is performed. Thus, since the first predetermined time T3 and the second predetermined time T4 are determined based on the behavior pattern when the user uses the vacuum cleaner 100, the notified timing is too early for the user. It's hard to get too late. Therefore, user convenience can be improved.

  Further, instead of obtaining the average value, the mode value or the median value may be obtained and used as the first predetermined time T3 and the second predetermined time T4. By doing in this way, even when a user's action pattern varies, it can notify at an appropriate timing.

  Alternatively, the time obtained by subtracting the predetermined time from the average value (or mode or median) may be set as the first predetermined time T3 and the second predetermined time T4. By doing in this way, notification will be performed at a timing earlier than the user's behavior pattern by a predetermined time. Therefore, it can be urged to shorten the time of the state where the power plug 7 is kept inserted or the continuous operation state of the electric blower 9 without difficulty while adjusting to the user's action pattern.

  Further, the method for obtaining the first predetermined time T3 and the second predetermined time T4 is not limited to the above-described method, and is appropriate based on the history of the main body energization time t41 and the electric blower energization time t42 stored in the storage unit 103. You may obtain | require by statistical processing.

  As described above, according to the fourth embodiment, in addition to the effects of the third embodiment described above, notification can be performed at a timing according to the user's behavior pattern, so that the user's convenience is improved. Can do. Note that the method described in the fourth embodiment may be applied to the first and second embodiments, and the same effect can be obtained.

In the above description, the notification of the notification unit 8 is stopped by the power switch 31, but an operation unit for stopping the notification unit 8 may be provided separately.
In the above description, an example in which notification is performed by both the light notification unit 8a and the voice notification unit 8b as the notification unit 8 has been described, but only one of them may be provided.
Further, instead of or in addition to the light notification unit 8a and the voice notification unit 8b, a display screen such as a liquid crystal screen may be provided to display a message for the user. By doing in this way, the content of an alert | report can be conveyed more correctly with respect to a user.

  Further, instead of the notification by the notification means 8 or in addition to the notification, the power plug 7 may be automatically detached from the outlet. In this case, a detaching means is provided in the power plug 7, and the detaching means is controlled to operate when the time measured by the timer 102 reaches a predetermined time. In this way, even when the user goes out with the power plug 7 inserted, for example, the power plug 7 is automatically disconnected from the outlet, so that the power plug 7 can be left unplugged. This can prevent the wasteful energization time.
