(An example of a form that a small electrical device and its control device can take)
In one example, a control device for a small electrical device is a control device for a small electrical device that changes the operation of a drive source of the small electrical device according to operation of a switch of the small electrical device, wherein the operation mode of the small electrical device is is the first operation mode, and the switch is operated in the first operation, changing the operation mode of the small electrical device to a second operation mode different from the first operation mode, and changing the operation mode of the small electrical device to When the switch is in the first operation mode and the switch is operated in a second operation different from the first operation, the operation mode of the small electrical appliance is changed from the first operation mode to the second operation mode without going through the second operation mode. 1 operation mode and a third operation mode different from the second operation mode.

In one example of the control device for a small electrical appliance, the first operation is one of a long press operation and a short press operation, and the second operation is the other of the long press operation and the short press operation.
In one example of the control device for small electrical equipment, the first operation mode is a stop mode for stopping the drive source.

In one example of the control device for small electrical equipment, the second operation mode is a drive mode for driving the drive source.
In one example of the control device for the small electric appliance, the third operation mode is a cleaning mode in which the drive source is driven for cleaning the small electric appliance, and the operation of the switch is the first operation or the second operation. It is one of the lock modes that does not change the operating mode of the small electrical appliance when it is operated.

In one example of the control device for the small electrical device, when the operation mode of the small electrical device is the second operation mode and the switch is operated in the first operation, the operation mode of the small electrical device is set to the first operation mode. change to mode.

In one example of the controller for the small electrical device, the operation mode of the small electrical device is the second operation mode, and when the switch is operated in the second operation, the operation mode of the small electrical device is set to the third operation. change to mode.

In one example of the controller for the small electrical device, when the operation mode of the small electrical device is the third operation mode and the switch is operated in the first operation, the operation mode of the small electrical device is set to the first operation mode. change to mode.

In one example, a small electrical appliance comprises a controller for said small electrical appliance.
In one example of the small electrical device, the switch is a single push button switch.
An example of the small electric appliance is an electric shaver.

In one example, a control device for a small electrical device is a control device for a small electrical device that includes a drive source and a switch that changes the operation of the drive source, and is a first criterion for determining the type of operation of the switch. and a second criterion, which is a criterion different from the first criterion, and the operation mode of the small electric device before the switch is operated, the small electric device after the switch is operated. Set the operating mode of the device.

According to the above control device, it is possible to set a plurality of operation modes of the small electrical device after the switch is operated by combining the operation mode of the small electrical device before the switch is operated and the operation type of the switch. be. That is, even if the operation type of the switch is the same, if the operation mode of the small electrical device before the switch is operated is different, the operation mode of the small electrical device after the switch is operated can be made different. Therefore, the operability of switching the operation of the small electric device is improved.

In one example of the control device for a small electrical appliance, the switch is a push button switch, and the first criterion is a period of time during which the switch is greater than or equal to a first determination time and less than a second determination time longer than the first determination time. The second determination criterion is a long press determination in which the switch is pressed for a period equal to or longer than the second determination time.

According to the above-described control device, since the types of switch operations are short press and long press, which are generally pervasive operations, it is possible to switch to various operation modes by operating the switch with which the user is accustomed. . Therefore, the operability of switching the operation of the small electric device is improved.

In one example of the control device for the small electrical device, the operation modes of the small electrical device include a stop mode for stopping the drive source, a drive mode for driving the drive source, and a drive mode for driving the drive source at a higher speed than the drive mode. In the stop mode, when the operation of the switch satisfies the first criterion and does not satisfy the second criterion, the stop mode is switched to the drive mode, and the stop mode, when the operation of the switch satisfies the second criterion, the stop mode is switched to the cleaning mode.

According to the control device, when the switch is operated until the second criterion is satisfied in the stop mode, the switch is switched to the cleaning mode. For this reason, after the user confirms dirt or the like adhering to the small electrical device in the stopped state, the user operates the switch until the second criterion is satisfied, thereby switching the small electrical device from the stop mode to the cleaning mode. . Therefore, the small electric device can be switched from the stop mode to the cleaning mode by operating the switch once. Therefore, the operability of switching the operation of the small electric device is improved.

In one example of the controller for the small electric appliance, in the stop mode, when the operation of the switch satisfies the first criterion, the driving source is driven, and the operation of the switch satisfies the second criterion. the stop mode is switched to the cleaning mode.

If the user operates the switch until the second criterion is satisfied, and there is no change in the operation of the small electrical device after the switch is operated, the user may perceive that the switch is malfunctioning. .

According to the control device, when the switch is operated until the second criterion is satisfied in the stop mode, the driving source is driven when the switch is operated until the first criterion is satisfied. This makes it difficult for the user to recognize that there is a problem with the switch.

In one example of the control device for the small electric device, the operation mode of the small electric device is a stop mode for stopping the drive source, a drive mode for driving the drive source, and the switch satisfies the first criterion. switching from the drive mode to the stop mode when the operation of the switch satisfies the first criterion and does not satisfy the second criterion in the drive mode; In the drive mode, when the operation of the switch satisfies the second criterion, the drive mode is switched to the lock mode.

The control device switches to the lock mode when the switch is operated in the drive mode until the second criterion is satisfied. Therefore, if the switch is not operated after the user uses the small electrical device, the drive mode is maintained, and in this state the small electrical device is driven by operating the switch until the user satisfies the second criterion. You can switch from mode to lock mode. Therefore, when the user switches to the lock mode by operating the switch after using the small electrical device, the user can switch to the lock mode with a single operation of the switch, which improves the operability of switching the operation of the small electrical device. do.

In one example of the controller for the small electric appliance, in the drive mode, when the operation of the switch satisfies the first criterion, the driving source is stopped, and the operation of the switch satisfies the second criterion. is switched from the drive mode to the lock mode.

If the user operates the switch until the second criterion is satisfied, and there is no change in the operation of the small electrical device after the switch is operated, the user may perceive that the switch is malfunctioning. .

According to the control device, when the switch is operated until the second criterion is satisfied in the drive mode, the drive source is stopped when the switch is operated until the first criterion is satisfied. This makes it difficult for the user to recognize that there is a problem with the switch.

In one example, a small electrical device includes the control device for the small electrical device and one push button switch as the switch.
According to the small electric device, the same effect as that of the control device for the small electric device can be obtained. In addition, since the switch of the small electrical device is a single push button switch, the user can switch between various operation modes of the small electrical device by pressing the single switch. Therefore, the operability of switching the operation of the small electrical device is improved compared to a configuration in which the small electrical device includes a plurality of switches.

(Embodiment)
The configuration of an electric shaver 1, which is an example of a small electric device, will be described with reference to FIG.
The electric shaver 1 comprises a body 10 and a head 20 operably attached to the body 10 .

The main body 10 has a grip 11 to be gripped by a user and one switch 12 attached to the grip 11 . An example of the switch 12 is a push button switch. A battery (not shown) is housed inside the grip 11 .

The main body 10 also includes a display portion 13 attached to the switch 12 on the side opposite to the head 20 in the longitudinal direction of the main body 10 . The display unit 13 displays the operating state of the electric shaver 1, the remaining battery level, and the like.

The head 20 includes an outer blade unit 22 , a head cover 24 to which the outer blade unit 22 is attached, and a pair of inner blade units (not shown) housed in the head cover 24 . A large number of holes 23A are formed in the outer blade 23 of the outer blade unit 22, and the user's beard, for example, is introduced into the head 20 through the holes 23A. The whiskers introduced into the head 20 are cut by being sandwiched between the outer blade 23 and an inner blade (not shown) of the inner blade unit. A linear motor 21 that is an example of a drive source is housed inside the head cover 24 . The linear motor 21 reciprocates the inner blade unit in the longitudinal direction of the head 20 by being supplied with power from the battery based on the operation of the switch 12 .

The electrical configuration of the electric shaver 1 will be described with reference to FIG.
The main body 10 (see FIG. 1) has a control device 30 that controls the operation of the electric shaver 1 . The control device 30 includes a control section 31 that controls the linear motor 21 and a drive circuit 36 that drives the linear motor 21 based on control signals from the control section 31 . An operation signal of the switch 12 is input to the control unit 31 . The operation signal is output when the switch 12 is pushed. Then, the control unit 31 detects the state of the switch 12 every predetermined time (every several milliseconds, for example).

The control unit 31 includes a switch determination unit 32 and a mode processing unit 33 . The control unit 31 includes a memory (not shown). The control unit 31 stores the current operating mode of the electric shaver 1 in memory.

The switch determination unit 32 determines whether the operation of the switch 12 is valid or invalid, and if the operation of the switch 12 is valid, the switch determination unit 32 determines whether the switch 12 is operated short-pressed or long-pressed as an example of the operation type of the switch 12 . make a judgment. The switch determination section 32 outputs the determination result of the operation of the switch 12 to the mode processing section 33 as a determination signal. The switch determination unit 32 determines whether the operation of the switch 12 is valid or invalid, and whether the switch 12 is pressed for a short time or a long time, based on the duration of the pressing operation of the switch 12 . Note that the time during which the switch 12 is pressed is the time during which the switch determination unit 32 continues the ON determination. The switch determination unit 32 determines ON when the switch 12 is pressed, that is, when an operation signal is input, and determines OFF when it is not pressed, that is, when an operation signal is not input. .

As shown in FIG. 3A, the switch determination unit 32 determines that the pressing operation time of the switch 12 (see both FIG. 2) is the time from time t0 when the pressing operation of the switch 12 is started to time t1. If it is less than the first determination time ST1, it is determined that the pressing operation of the switch 12 is invalid. Note that the first determination time ST1 is an example of a first determination criterion. The switch determination unit 32 determines that the pressing operation of the switch 12 is valid when the pressing operation time of the switch 12 is equal to or longer than the first determination time ST1. The first determination time ST1 is the shortest time during which it can be determined that the switch 12 has been pressed, and is set in advance by testing or the like.

As shown in FIG. 3B, the switch determination unit 32 determines that the pressing operation of the switch 12 is longer than the first determination time ST1 and is the time from time t0 to time t2, which is later than time t1. If the time is less than a certain second determination time ST2, it is determined that the switch 12 has been pressed for a short time. Note that the second determination time ST2 is an example of a second determination criterion. As shown in FIG. 3(c), the switch determination unit 32 determines that the switch 12 has been long-pressed when the duration of the pressing operation of the switch 12 is longer than or equal to the second determination time ST2. The second determination time ST2 is the shortest time during which it can be determined that the switch 12 has been pressed for a long time, and is set in advance by testing or the like. Also, the first determination time ST1 and the second determination time ST2 are stored in the memory of the control section 31 .

As shown in FIG. 2 , the mode processing unit 33 determines the operating state of the electric shaver 1 and outputs a control signal corresponding to the operating state of the electric shaver 1 to the drive circuit 36 . The mode processing unit 33 includes a mode determination unit 34 that determines the operation mode of the electric shaver 1 and a mode switching unit 35 that switches the operation mode based on the operation of the switch 12 , that is, the determination signal of the switch determination unit 32 .

Operation modes of the electric shaver 1 include a stop mode, a drive mode, a cleaning mode, and a lock mode.
The stop mode is a control state in which the operation of the head 20 (see FIG. 1) of the electric shaver 1 is stopped, that is, the control state in which the drive of the linear motor 21 is stopped.

The driving mode is a control state in which the head 20 of the electric shaver 1 performs an operation suitable for shaving the user's beard, that is, the linear motor 21 is driven at a reciprocating speed and amplitude suitable for shaving the user's beard. This is the control state for driving.

The cleaning mode is a control state in which the head 20 of the electric shaver 1 performs an operation suitable for cleaning the head 20, that is, the linear motor 21 is operated at a reciprocating speed and amplitude suitable for cleaning the head 20. This is the control state for driving. As an example, the amplitude of linear motor 21 in cleaning mode is smaller than the amplitude of linear motor 21 in drive mode. Also, the number of strokes of the linear motor 21 in the cleaning mode is higher than the number of strokes of the linear motor 21 in the driving mode. The number of strokes is the number of reciprocations of the linear motor 21 per unit time.

The lock mode is a state in which a short press of the switch 12 is disabled, that is, a state in which the operation mode of the electric shaver 1 is not changed even if the switch 12 is briefly pressed. When the switch determination unit 32 determines that the switch 12 is pressed for a short time in the lock mode, an icon (for example, a padlock) indicating the lock mode is displayed on the display unit 13 (see FIG. 1).

The mode determination unit 34 reads out the current operation mode from the memory of the control unit 31 and outputs it to the mode switching unit 35 . The operation mode (current operation mode) read from the memory by the mode determination unit 34 becomes the operation mode before the switch 12 is operated.

The mode switching unit 35 operates the switch 12 using a table showing the relationship between the current operation mode of the electric shaver 1 shown in FIG. Switch between later operating modes. Note that the operation mode after the operation of the switch 12 is overwritten in the memory of the control section 31 . Therefore, when the switch 12 is operated next time, the operation mode after the operation of the switch 12 in the previous operation of the switch 12 becomes the current operation mode.

As shown in FIG. 4, the mode switching unit 35 switches from the stop mode to the drive mode when the switch 12 is pressed for a short time when the current operation mode is the stop mode. The mode switching unit 35 switches from the stop mode to the cleaning mode when the switch 12 is pressed long while the current operation mode is the stop mode. The mode switching unit 35 switches from the cleaning mode to the stop mode when the switch 12 is pressed for a short time when the current operation mode is the cleaning mode.

When the mode switching unit 35 switches from the stop mode to the cleaning mode, the linear motor 21 is driven as follows. When the current operation mode is the stop mode and the switch determination unit 32 determines that the pressing operation of the switch 12 is valid, the linear motor 21 is driven under the conditions of the drive mode. When the switch determination unit 32 determines that the switch 12 has been pressed for a long time, the linear motor 21 is driven under the washing mode condition.

The mode switching unit 35 switches from the drive mode to the stop mode when the switch 12 is pressed for a short time when the current operation mode is the drive mode. The mode switching unit 35 switches from the drive mode to the lock mode when the switch 12 is pressed long while the current operation mode is the drive mode. The mode switching unit 35 switches from the lock mode to the drive mode when the switch 12 is pressed long while the current operation mode is the lock mode. The mode switching unit 35 maintains the lock mode even if the switch 12 is pressed for a short time when the current operation mode is the lock mode.

When the mode switching unit 35 switches from the drive mode to the lock mode, the linear motor 21 is driven as follows. When the current operation mode is the drive mode and the switch determination unit 32 determines that the pressing operation of the switch 12 is valid, the driving of the linear motor 21 is stopped. Even when the switch determination unit 32 determines that the switch 12 has been pressed for a long time, the drive of the linear motor 21 is kept stopped.

The action of the electric shaver 1 will be described.
As a conventional electric shaver, there is known one in which the electric shaver is switched to a cleaning mode based on long-pressing of a switch regardless of whether the electric shaver is in a stop mode or a drive mode. Another conventional electric shaver is known to be switched to a lock mode based on long-pressing of a switch regardless of whether the other electric shaver is in a stop mode or a drive mode.

These conventional electric shavers do not consider the operation mode before operating the switch, and switch the operation mode between the cleaning mode and the lock mode based only on the long press of the switch. Therefore, only one type of operation mode can be switched for a long press of the switch.

On the other hand, the electric shaver 1 switches from the stop mode to the cleaning mode when the current operation mode is the stop mode and the switch 12 is pressed and held, and when the current operation mode is the drive mode and the switch 12 is pressed and held for a long time, the electric shaver 1 is driven. mode to lock mode. Therefore, it is possible to switch between two operation modes by pressing the switch 12 for a long time. Therefore, the operability of switching the operation mode of the electric shaver 1 is improved.

This embodiment can produce the following effects.
(1) The electric shaver 1 switches the operation mode after the switch 12 is operated based on the current operation mode (the operation mode before the switch 12 is operated) and the operation type of the switch 12 . Therefore, by combining the current operation mode and the operation type of the switch 12, it is possible to set a plurality of operation modes after the switch 12 is operated. That is, even if the operation type of the switch 12 is the same, if the current operation mode is different, the operation mode after the switch 12 is operated can be made different. As a result, even if the electric shaver disclosed in Patent Document 1 does not have both a switch and a locking device, only the switch 12 can switch the operation mode and switch the switch 12 between the locked state and the unlocked state. becomes possible. Therefore, the operability of switching the operation mode of the electric shaver 1 is improved.

(2) Since the operation types of the switch 12 are short press and long press, it is possible to switch to various operation modes by operating the switch 12 with which the user is accustomed. Therefore, the operability of switching the operation mode of the electric shaver 1 is improved.

(3) When the user visually recognizes the head of the electric shaver and finds that the head has a beard, the user recognizes that the head needs to be washed, and switches to a washing mode for washing the head. Thus, the electric shaver is preferably in a state where the head is stopped so that the user can check whether or not the hair is attached to the head. The shaver is then preferably switched from the stop mode to the cleaning mode. In addition, when the head is driven by the user operating the switch from the state where the head is stopped and then the electric shaver is switched to the cleaning mode by operating the switch again, the user does not have to operate the switch twice. be. For this reason, the operability of switching the operation mode of the electric shaver is deteriorated.

When the current operation mode of the electric shaver 1 is the stop mode and the switch 12 is pressed for a long time, the electric shaver 1 switches to the cleaning mode. Therefore, when the user presses the switch 12 for a long time after confirming that the head 20 has stopped, the electric shaver 1 can be switched from the stop mode to the cleaning mode. is switched to cleaning mode. Therefore, the operability of switching the operation mode of the electric shaver 1 is improved.

(4) When a user uses an electric shaver before going out and carries the electric shaver in a bag or the like, the electric shaver must be in the lock mode to prevent the electric shaver from being driven by mistake. preferable. Further, when the user uses the electric shaver, operates the switch to stop the head, and then operates the switch again to switch the electric shaver to the lock mode, the user needs to operate the switch twice. For this reason, the operability of switching the operation mode of the electric shaver is deteriorated.

The electric shaver 1 switches to the lock mode when the current operation mode is the drive mode and the switch 12 is pressed for a long time. Therefore, if the switch 12 is not operated after the user uses the electric shaver 1, the electric shaver 1 maintains the driving mode, and when the user presses the switch 12 for a long time in this state, the electric shaver 1 is driven. mode to lock mode. Therefore, when the user operates the switch 12 after using the electric shaver 1 to switch to the lock mode based on the operation of the switch 12 , the lock mode can be switched to by operating the switch 12 once. improve sexuality.

(5) When the user presses the switch for a long time, if the operation mode of the electric shaver does not change after the switch is operated, the user may perceive that the switch is malfunctioning.

When the current operation mode is the stop mode and the switch 12 is pressed for a long time, the electric shaver 1 drives the linear motor 21 under the condition of the drive mode when it is determined that the pressing operation of the switch 12 is valid. In the electric shaver 1, when the current operation mode is the drive mode and the switch 12 is pressed for a long time, the linear motor 21 stops when the pressing operation of the switch 12 is determined to be valid. As described above, the electric shaver 1 switches the operation when the switch 12 is pushed, so that the user is less likely to recognize that the switch 12 is malfunctioning.

(6) The electric shaver 1 has one push button switch as the switch 12 . Therefore, it is possible to switch between the four operation modes by short-pressing and long-pressing one switch 12 . Therefore, the operability of switching the operation modes of the electric shaver 1 is improved compared to the case where the four operation modes are switched based on the operation of a plurality of switches.

(7) Of the operation modes of the electric shaver 1, namely stop mode, drive mode, cleaning mode, and lock mode, the stop mode and drive mode are used more frequently than the cleaning mode and lock mode.

The electric shaver 1 switches between a stop mode and a drive mode based on a short press of the switch 12 . Therefore, compared to the case where the stop mode and the drive mode are switched based on the long press of the switch 12, it is possible to easily switch between the stop mode and the drive mode, which are used frequently.

(8) The electric shaver 1 causes the display unit 13 to display an icon indicating the lock mode when the switch 12 is pressed for a short time when the current operation mode is the lock mode. This makes it easier for the user to recognize that the electric shaver 1 is in lock mode.

- In the above-described embodiment, the electric shaver 1 may be provided with a hair sensor for detecting that hair is inserted into the hole 23A of the outer blade 23 . In this case, instead of the lock mode or the cleaning mode, the electric shaver 1 operates in a hair sensor mode in which the amplitude of the linear motor 21 is changed from the amplitude of the linear motor 21 in the drive mode based on insertion of hair into the hole 23A. You may prepare. As an example, if the electric shaver 1 has a beard sensor mode instead of the lock mode, the mode switching unit 35 switches from the drive mode to the beard sensor mode when the switch 12 is pressed long while the current operation mode is the drive mode. . When the switch 12 is pressed long while the current operation mode is the beard sensor mode, the mode switching unit 35 switches from the beard sensor mode to the drive mode. As another example, if the electric shaver 1 has a beard sensor mode in place of the cleaning mode, the mode switching unit 35 switches the current operation mode from the stop mode to the beard sensor mode when the switch 12 is held down while the current operation mode is the stop mode. switch to When the switch 12 is pressed long while the current operation mode is the beard sensor mode, the mode switching unit 35 switches from the beard sensor mode to the stop mode. It should be noted that the electric shaver 1 may also have a beard sensor mode instead of either the cleaning mode or the lock mode in the table shown in FIGS. 5(a) and 5(b).

- The table shown in FIG. 4 and the tables shown in FIGS. 5(a) and 5(b) in the above embodiment may have a beard sensor mode instead of the drive mode.

In the table shown in FIG. 4 and the tables shown in FIGS. 5(a) and 5(b) in the above embodiment, instead of pressing the switch 12 for a long time, the switch 12 is pressed twice within a predetermined time. The operation mode may be changed based on being pressed.
