Technical Field

An embodiment of the invention relates to an electric dust collector, which is provided with an electric blower driven by power supply from a secondary battery.

Background

Conventionally, in a rechargeable electric vacuum cleaner using a rechargeable battery, i.e., a secondary battery, as a power source, an electric blower is incorporated therein for sucking dust. The electric blower controls the suction force by PWM (Pulse Width Modulation) control, for example. With the PWM control, the suction force of the electric blower is increased when the duty ratio, which is the ratio at which the current waveform supplied to the electric blower is ON, is high, and the suction force of the electric blower is decreased when the duty ratio is low. In such a rechargeable electric vacuum cleaner, since the capacity of the secondary battery is limited, the time during which cleaning is possible, i.e., the operable time, is shortened when the duty ratio is high and the suction force of the electric blower is increased.

As a method of changing the duty ratio, for example, there is a method based on manual operation by a user. For example, two switches of strong and weak are provided in the manual operation unit, and if the user operates the strong switch, the electric blower is controlled at a relatively large duty ratio for strong operation, and if the user operates the weak switch, the electric blower is controlled at a relatively small duty ratio for weak operation.

In addition, as an automatic control method of the duty ratio, for example, there is a method in which a sensor for detecting the amount of dust sucked by driving the electric blower is provided in order to secure a time period in which cleaning is possible, and the duty ratio is increased as the amount of dust detected by the sensor is relatively increased.

Further, as another automatic control method of the duty ratio, it is disclosed to decrease the duty ratio according to an increase in the number of times of charging of the secondary battery. Since the secondary battery has a capacity capable of storing electricity that decreases as the number of times of charging increases, the duty ratio decreases in accordance with the increase in the number of times of charging, thereby reducing the current flowing through the electric blower and suppressing the reduction in the time during which cleaning is possible.

The necessary cleaning time and the suction force vary from user to user depending on the size of the area to be cleaned, the degree of uncleanness, and the like, and it is difficult for the user to grasp these situations. Therefore, it is desirable to automatically optimize cleanable time and appeal in correspondence with the user.

The electric dust collector of the embodiment comprises an electric blower, a dust collecting part, a residual amount detection unit and a control unit. The electric blower is driven by power supplied from the secondary battery. The dust collecting section captures and collects dust sucked by the driving of the electric blower. The remaining amount detecting unit detects a remaining amount of the secondary battery. The control unit controls the suction force of the electric blower according to the parameter. The control unit sets parameters so that the suction force of the electric blower is reduced when cleaning is finished in a state where the remaining amount of the secondary battery detected by the remaining amount detection unit is equal to or less than a predetermined value. The control unit sets a parameter so that the suction force of the electric blower is increased at the next cleaning when the cleaning is finished in a state where the remaining amount of the secondary battery detected by the remaining amount detection unit is not equal to or less than a predetermined value.
