The first control unit 8 may be constituted by a plurality of control boards. These plurality of control substrates may be connected by signal lines or electric wires. The first control unit 8 is constituted by, for example, a control board including a drive circuit for the electric blower and the first detection circuit 5, a control board including a drive circuit for the rotary brush, a control board including a charging circuit, a control board including a coulomb counter, a microcontroller, and the like. These circuits and the like may be mounted on the same control board.
The first storage unit 36 of the first control unit 8 is provided with control software for controlling the electric vacuum cleaner 50. The control software can include firmware that controls the electric blower 4, the second motor 18, the battery 12, and the like. The firmware may be regarded as a part of the electric blower 4, the second motor 18, the battery 12, and the like.
The first control portion 8 can have a first adjustment portion 37, the first adjustment portion 37 being provided to adjust the power or current supplied from the battery 12 to the first motor 3 of the electric blower 4. The first adjusting unit 37 is, for example, a part of a drive circuit for the electric blower. The first adjusting section 37 can include a PWM circuit having a transistor. The power supplied from the battery 12 to the first motor 3 can be adjusted by adjusting the repetition period or duty ratio of the on-off of the transistor.
The first control section 8 can contain a first detection circuit 5, which first detection circuit 5 is arranged to detect the current or the power supplied from the battery 12 to the first motor 3. The first control unit 8 may be configured to calculate the power consumption of the electric blower 4 based on the output of the first detection circuit 5. For example, the power consumption of the electric blower 4 can be calculated based on the current and the supply voltage calculated based on the output of the first detection circuit 5.
The first control part 8 may have a second adjustment part 38, which second adjustment part 38 is arranged to adjust the power or current supplied from the battery 12 to the second motor 18 rotating the rotary brush 17. The second regulating section 38 can include a PWM circuit having a transistor. The power supplied from the battery 12 to the second motor 18 can be adjusted by adjusting the repetition period or duty cycle of the turning on and off of the transistor.
The first control part 8 can comprise a second detection circuit 6, which second detection circuit 6 is arranged to detect the current or the power supplied from the battery 12 to the second motor 18. Further, the first control section 8 can be configured to calculate the power consumption of the second motor 18 based on the output of the second detection circuit 6. For example, the power consumption of the second motor 18 can be calculated based on the current and the supply voltage calculated based on the output of the second detection circuit 6.
The first control section 8 can include, for example, a voltage detection circuit configured to detect a battery voltage of the battery 12. The first control unit 8 can calculate the remaining battery level of the battery 12 based on the output of the voltage detection circuit.
When the electric vacuum cleaner 50 is operated with the battery 12 as a power source, power is supplied from the battery 12 to the electric blower 4 or the like, and the battery remaining amount of the battery 12 gradually decreases. When the remaining battery power is reduced to a level at which the operation is stopped (the battery voltage reaches the end voltage), the vacuum cleaner 50 stops the operation, and notifies the operator of the need to charge the battery 12 or the need to replace the battery 12 via the notification unit 23.
The battery voltage of the battery 12 gradually decreases as the battery residual amount of the battery 12 decreases. Therefore, the first control unit 8 can calculate the remaining battery level of the battery 12 by detecting the battery voltage of the battery 12 using the voltage detection circuit. The first control unit 8 can calculate the amount of electricity that the battery 12 can supply to the electric blower 4 or the like based on the battery voltage or the battery remaining amount of the battery 12.
The first control section 8 can contain a coulomb counter configured to measure the current flowing into the battery 12 and the current flowing out of the battery 12 using a coulomb counting method. In addition, the first control section 8 can be configured to calculate the battery remaining amount of the battery 12 based on the output of the coulomb counter.
The operable time of the electric vacuum cleaner 50 using the battery 12 as a power source can be calculated from the energy (Wh) that can be taken out from the battery 12 and the power consumption (Wh) of the electric vacuum cleaner 50. When the electric vacuum cleaner 50 is operated in a single operation mode (for example, a strong operation mode, a weak operation mode, and an automatic operation mode), power consumption becomes an amount of electricity corresponding to the operation mode. Therefore, when the electric vacuum cleaner 50 is operated in the single operation mode, the operable time of the electric vacuum cleaner 50 can be calculated from the battery capacity, the battery margin (or the battery voltage), the power consumption, and the like of the battery 12.
Further, the power of the electric vacuum cleaner 50 for operating the electric vacuum cleaner 50 for a predetermined time may be calculated based on the energy (Wh) that can be taken out from the battery 12 and the operating time of the electric vacuum cleaner 50.
When the operator operates the operation unit 32 to change the electric vacuum cleaner 50 into the power mode, when the garbage detection sensor 30 detects a large amount of garbage to increase the suction force of the electric vacuum cleaner 50, when the first control unit 8 detects a carpet to increase the suction force of the electric vacuum cleaner 50, or the like, there is a possibility that the power consumption of the electric vacuum cleaner 50 is greater than that in the operation mode. In this case, since the electric cleaner 50 consumes a large amount of power, the time required for operation is also shortened.
As described above, when the operation time becomes short, the operator may fail to clean the predetermined cleaning range.
When the filter of the dust collection unit 11 becomes dirty, the power consumption of the electric blower 4 becomes small, and the operation time of the electric vacuum cleaner 50 becomes long.
The first control unit 8 is configured to adjust the electric power supplied from the battery 12 to the first motor 3 based on the power consumption of the electric vacuum cleaner 50 and the battery remaining amount or the battery voltage of the battery 12 so that the electric vacuum cleaner 50 can be operated for a predetermined time. This regulation of the supply of power is performed during operation of the electric vacuum cleaner 50. This can suppress shortening of the operation time set at the start of the operation, and suppress failure of the operator to clean the predetermined cleaning range. Further, even when the suction force of the electric vacuum cleaner 50 is increased by an operation of an operator, detection of a sensor, or the like, the electric vacuum cleaner 50 can be operated for a predetermined time. This will be described using a flowchart.
Fig. 3 is a control flow chart of the electric vacuum cleaner 50, and fig. 4 is a graph schematically showing a change with time of electric power supplied from the electric blower 4 to the first motor 3.
First, the operator presses a button of the operation unit 32 to select an operation mode, and starts the operation of the electric vacuum cleaner 50.
In step S1, the first control unit 8 calculates the operable time of the electric vacuum cleaner 50 from the power consumption, the battery capacity of the battery 12, and the battery remaining amount (or battery voltage) when the electric vacuum cleaner 50 is operated in the selected operation mode, and sets the calculated operable time as the operation time (target operation time). The first control unit 8 controls the electric vacuum cleaner 50 so that the electric vacuum cleaner 50 can be operated during the set operation time.
After starting the operation in the selected operation mode (step S2), the power consumption of the electric vacuum cleaner 50 is calculated (step S3).
For example, the amount of change in the battery remaining amount of the battery 12 or the amount of change in the battery voltage is calculated based on the output of the voltage detection circuit or the output of the coulomb counter, and the power consumption of the electric vacuum cleaner 50 is calculated based on the amount of change.
Further, for example, the power consumption of the electric blower 4 is calculated based on the output of the first detection circuit 5, and the power consumption of the second motor 18 is calculated based on the output of the second detection circuit 6. These power consumptions are combined with the power consumption of the first control unit 8 and the like to calculate the power consumption of the electric vacuum cleaner 50.
In step S4, the electric power supplied to the first motor 3 of the electric blower 4 is adjusted by the first adjusting portion 37 based on the remaining operable time, the power consumption of the electric vacuum cleaner 50, the battery capacity of the battery 12, the battery margin (or the battery voltage), and the like, so that the electric vacuum cleaner 50 can be operated for the remaining operable time. In addition, the second adjusting unit 38 may be used to adjust the electric power supplied to the second motor 18. Then, the electric vacuum cleaner 50 is operated with the adjusted supplied electric power (step S5).
In step S6, it is determined whether or not the operator presses the power mode button of the operation unit 32. When the power mode button is pressed, the first control unit 8 temporarily increases the power supplied to the electric blower 4 by the first adjustment unit 37, thereby temporarily increasing the suction force (first power mode) of the electric vacuum cleaner 50 (steps S7 and S8). The time for operating in the first power mode can be set to, for example, 5 seconds. In the first power mode, since the power consumption of the electric vacuum cleaner 50 increases, the rate of decrease in the battery remaining amount of the battery 12 increases. Therefore, the battery remaining amount of the battery 12 after the end of the first power mode is smaller than the expected battery remaining amount.
After the operation in the first power mode is completed, steps S2 to S4 are repeated, and the electric power supplied to the first motor 3 of the electric blower 4 is adjusted by the first adjusting unit 37. The power provided after conditioning is smaller than the power provided before conditioning. Thus, even when the first power mode is used, the electric vacuum cleaner 50 can be operated for the operation time period set at the start of operation. For example, the power supplied to the first motor 3 may vary such as the graph shown in fig. 4. In addition, in step S2 after step S8, the electric vacuum cleaner 50 is operated with the supply power adjusted in step S4 performed before returning to step S2.
This process is repeated for each operation in the first power mode.
In step S9, the first control unit 8 can determine whether or not the carpet is being cleaned based on the torque level or change of the second motor 18. When cleaning a carpet, the first control unit 8 increases the power supplied to the electric blower 4 by the first adjusting unit 37, thereby increasing the suction force (second power mode) of the electric vacuum cleaner 50. The first control unit 8 increases the power supplied to the second motor 18 by the second adjustment unit 38, thereby increasing the torque of the rotary brush 17 (second power mode) (steps S10 and S11).
In the second power mode, since the power consumption of the electric vacuum cleaner 50 becomes large, the rate of decrease in the battery remaining amount of the battery 12 becomes large. Therefore, the battery remaining amount of the battery 12 after the end of the second power mode is smaller than the expected battery remaining amount.
After the operation in the second power mode is completed, steps S2 to S4 are repeated, and the electric power supplied to the first motor 3 of the electric blower 4 is adjusted by the first adjusting unit 37. The power provided after conditioning is smaller than the power provided before conditioning. Thus, even when the second power mode is used, the electric vacuum cleaner 50 can be operated for the operation time period set at the start of operation. For example, the power supplied to the first motor 3 may vary such as the graph shown in fig. 4. In addition, in step S2 following step S11, the electric vacuum cleaner 50 is operated with the supply power adjusted in step S4 performed before returning to step S2.
This process is repeated each time a carpet is detected.
In step S12, the first control unit 8 determines whether or not the electric vacuum cleaner 50 is sucking a large amount of garbage based on the output of the garbage detection sensor 30. When a large amount of garbage is sucked, the first control unit 8 increases the power supplied to the electric blower 4 by the first adjusting unit 37, thereby increasing the suction force (third power mode) of the electric vacuum cleaner 50 (steps S13 and S14).
In the third power mode, since the power consumption of the electric vacuum cleaner 50 increases, the rate of decrease in the battery remaining capacity of the battery 12 increases. Therefore, the battery remaining amount of the battery 12 after the end of the third power mode is smaller than the expected battery remaining amount.
After the operation in the third power mode is completed, steps S2 to S4 are repeated, and the electric power supplied to the first motor 3 of the electric blower 4 is adjusted by the first adjusting unit 37. The power provided after conditioning is smaller than the power provided before conditioning. Thus, even when the third power mode is used, the electric vacuum cleaner 50 can be operated for the operation time period set at the start of operation. In addition, in step S2 subsequent to step S14, the electric vacuum cleaner 50 is operated with the supply power adjusted in step S4 performed before returning to step S2.
This process is repeated each time a suction of a large amount of garbage is detected.
In step S15, it is determined whether or not a predetermined time has elapsed since the power supplied was adjusted in step S4. The predetermined time may be, for example, 20 seconds. After a predetermined time has elapsed, steps S2 to S4 are repeated, and the electric power supplied to the first motor 3 of the electric blower 4 is adjusted by the first adjusting unit 37. This allows fine adjustment of the electric power supplied to the first motor 3. In addition, in step S2 subsequent to step S15, the electric vacuum cleaner 50 is operated with the supply power adjusted in step S4 performed before returning to step S2.
In step S16, it is determined whether or not the operation mode (weak operation mode, strong operation mode, automatic operation mode) is changed by the operator operating the operation unit 32. When the operation mode is changed, the routine returns to step S1, and the operation time is reset.
Next, in step S17, the first control unit 8 determines whether or not the remaining battery level of the battery 12 has decreased to a level at which the operation is stopped. If the remaining battery power does not reach the level at which the operation is stopped, the routine returns to step S5, and the electric vacuum cleaner 50 continues to operate. When the remaining battery power reaches a level at which the operation is stopped, the operation of the vacuum cleaner 50 is stopped, and the notification unit 23 notifies the operator that the battery 12 needs to be charged or replaced.
Second embodiment
The first control unit 8 is configured to notify the operator of the remaining operable time via the notification unit 23 during operation of the electric vacuum cleaner 50. After the operation time is set in step S1 of the flowchart shown in fig. 3, if the electric vacuum cleaner 50 continues to operate, the operation time decreases with the lapse of time. The operator is notified of the reduced remaining operable time via the notification section 23.
For example, when the notification unit 23 has a lamp (for example, LED), the operator can be notified of the remaining operable time by lighting, blinking, turning off, or the like of the lamp. In addition, in the case where the notification section 23 has a digital display section, the first control section 8 can be configured to notify the operator of the remaining operable time by using the digital display section. In addition, in the case where the notification portion 23 has a speaker, the first control portion 8 can be configured to notify the operator of the remaining operable time by voice.
Other configurations are the same as those of the first embodiment. The description of the first embodiment is also applicable to the second embodiment as long as there is no contradiction.
Third embodiment
Although the first control unit 8 sets the operation time based on the operation mode selected by the operator in step S1 of the flowchart shown in fig. 3, in the third embodiment, the first control unit 8 sets the operation time using the external device 21 that can communicate with the electric vacuum cleaner 50 (first control unit 8) via the first communication unit 20.
The external device 21 is a device provided with a display unit 43 and an input unit 44. The external device 21 is a portable terminal such as a smart phone, a tablet computer, a mobile phone, and the like. When the external device 21 includes a touch panel display, the touch panel display is a display unit 43 and an input unit 44. The external device 21 further includes a second control unit 41, a second storage unit 42, a second communication unit 45, and the like.
A method of setting the operation time using the external device 21 in step S1 will be described.
The first control unit 8 of the electric vacuum cleaner 50 transmits the battery remaining amount or the battery voltage of the battery 12 to the second control unit 41 of the external device 21 via the first communication unit 20 and the second communication unit 45. The first control unit 8 may send information on the battery capacity of the battery 12 and the power consumption of the vacuum cleaner 50 to the second control unit 41. The second storage unit 42 of the external device 21 may store information on the battery capacity of the battery 12 and the power consumption of the electric vacuum cleaner 50.
The second control unit 41 of the external device 21 calculates the operable time of the electric vacuum cleaner 50 and the power of the electric vacuum cleaner 50 corresponding to the operable time based on the battery remaining amount or the battery voltage of the battery 12 and information on the battery capacity of the battery 12 and the power consumption of the electric vacuum cleaner 50. Then, the second control section 41 causes the display section 43 to display the adjustment bar 46 as shown in fig. 5. The display unit 43 of the external device 21 shown in fig. 5 is a touch panel display having functions of the display unit 43 and the input unit 44.
The shortest operable time and the maximum power can be calculated using either the lower value of the upper limit value of the output of the first motor 3 or the upper limit value of the output of the battery 12.
The longest operable time and the minimum power can be calculated using the lowest rotational speed of the first motor 3. In addition, in the case where the dust collecting unit 11 includes a cyclone, the maximum operable time and the minimum power can be calculated based on the minimum output of the cyclone that can perform cyclone separation.
The operator moves the adjustment slide of the adjustment bar 46 to adjust to the desired run time and power. The second control unit 41 changes the operation time and power displayed on the display unit 43 according to the position of the adjustment slider. In addition, the operator can also adjust the operating time and power by inputting the operating time or power digitally.
After adjusting the operation time and power, the operator presses the transmission button displayed on the display unit 43 (input unit 44). When the transmission button is pressed, the second control unit 41 transmits the adjusted operation time to the first control unit 8 via the first communication unit 20 and the second communication unit 45.
The first control unit 8 sets the received operation time as the operation time of the electric vacuum cleaner 50.
The flow after step S2 is the same as the first embodiment.
The second control unit 41 can cause the display unit 43 to display the operation time (for example, the reciprocal) remaining during the operation of the vacuum cleaner 50. Thus, the operator can know the remaining operable time.
The other constitution is the same as the first or second embodiment. The description of the first or second embodiment is also applicable to the third embodiment as long as there is no contradiction.
