- Embodiments also provide a vacuum cleaner including an auxiliary power supply device, which charges the vacuum cleaner with low-priced electricity through a smart grid and is mounted at the vacuum cleaner to provide the charged electricity as an operating power thereof.

- Moreover, the auxiliary power supply device confirms whether an electricity price is less than the maximum price set by a user and performs charging in a power management network including an advanced metering infrastructure and an energy management unit. Therefore, relatively low-priced electricity is charged and then is supplied as an operating power of the vacuum cleaner.
- Furthermore, a display for notifying whether the auxiliary power supply device is available and the insufficiency of charging amount while charged electricity is used is equipped at the handle of the vacuum cleaner, so that a user may select a supply power of the vacuum cleaner according to a status of the auxiliary power supply device.

FIG. 6 is a flowchart illustrating charging operations of an auxiliary power supply device of a vacuum cleaner, and supplying operations of the charged electricity according to an embodiment.FIG. 7 is a flowchart illustrating a selective power supply structure for an operation of a vacuum cleaner according to an embodiment. - In order to use the auxiliary
power supply device 800, i.e., one of power supply sources of thevacuum cleaner 100, the auxiliarypower supply device 800 is connected to thepower management network 10 for charging (S10). - That is, as the charging
plug 820 is connected to thesocket 52, theEMS 30 is connected to the auxiliarypower supply device 800 for two-way communication, and in that connection status, power supply information including a charging available power supply source and a supply available electricity price is provided to the auxiliarypower supply device 800 through the EMS 30 (S12). - Additionally, the auxiliary
power supply device 800 confirms a power supply source having an electricity price lower than that set in the power supply device control unit 860 (S14), and then, electricity for charging the chargingunit 846 is supplied from the confirmed power supply source (S16). - Additionally, if the auxiliary
power supply device 800 cannot confirm a power supply source having an electricity price lower than that set in the power supplydevice control unit 860, a charging stand-by status is maintained, so that electricity for charging the chargingunit 846 is not supplied (S18, S24). - Moreover, when the charging of the charging
unit 846 is completed after the electricity is supplied from the low-priced power supply source (S20), a charging completion status of the auxiliarypower supply device 800 is delivered to theEMS 30 through the charging plug communication unit 827 (S22). - Then, when a user inserts the
cleaner plug 120 into thesocket 52 for mounting in order to operate thevacuum cleaner 100 in the above status, thedisplay 340 at thehandle 300 of thevacuum cleaner 100 displays an available status from theEMS 30 as the charging of the auxiliarypower supply device 800 is completed. - Accordingly, after a user confirms the available status, the auxiliary
power supply device 800 is mounted on the main body 110 (S26), and the mounted auxiliarypower supply device 800 supplies the charged power to the cleanerpower management unit 184 in order to use it as an operating power of the vacuum cleaner 100 (S28, S30). - Moreover, if the charging amount of the charging
unit 846 is reduced to less than a standard capacity while thevacuum cleaner 100 is used with the provided charged power (S32), the power supplydevice controlling unit 860 sends a message to thedisplay 340 through the power supplydevice communication unit 870, which notifies that the power of thevacuum cleaner 100 in use needs to be replaced due to the insufficiency of the charging amount (S34). - Furthermore, when the user confirms the message, the auxiliary
power supply device 800 is separated from themain body 110, and is connected to thesocket 52 again for charging. - Additionally, when the
vacuum cleaner 100 is completely used (S36), the auxiliarypower supply device 800 may be connected to thesocket 52 for charging. In this case, without separating the auxiliarypower supply device 800 from the cleanermain body 110, charging may be accomplished. - Referring to
FIG. 7 , thevacuum cleaner 100 is connected to the power management network 10 (S40). A determination is made whether the auxiliarypower supply device 800 is available at the vacuum cleaner 100 (S42). If the auxiliarypower supply device 800 is not available, then the operating power of thevacuum cleaner 100 is supplied through the power management network 10 (S44). If the auxiliarypower supply device 800 is available at thevacuum cleaner 100, the vacuum cleaner may be disconnected from the power management network 10 (S46). The auxiliarypower supply device 800 supplies the charged power to the cleanerpower management unit 184 to use it as an operating power of the vacuum cleaner 100 (S48, S50). - If the charging amount of the charging
unit 846 is reduced to less than a standard capacity while thevacuum cleaner 100 is used with the provided charged power (S52), the power supplydevice controlling unit 860 sends a message to thedisplay 340 through the power supplydevice communication unit 870, which notifies that the power of thevacuum cleaner 100 in use needs to be replaced due to the insufficiency of the charging amount (S54). Otherwise, a determination is made whether the cleaning is completed (S56). - If there is insufficient operating power in the auxiliary
power supply device 800, the vacuum cleaner is connected to the power management network (S58). The power management network supplies the operating power to the vacuum cleaner 100 (S44). Meanwhile, the auxiliarypower supply device 800 may be charged by thepower management network 10. A determination is made whether the auxiliarypower supply device 800 is charged to operate the vacuum cleaner 100 (S60). If the auxiliarypower supply device 800 is charged, thevacuum cleaner 100 may be disconnected from the power management network 10 (S62). - According to the embodiments, a power for operating a vacuum cleaner may be provided separately through a power supply path connecting a power management network and a cleaner plug and a power supply path connected to an auxiliary power supply device at one side of a main body to supply charging power.
- Additionally, in relation to the power supply path including the auxiliary power supply device, an available status is notified to a user through a smart grid, so that the user may preferentially use an operating power of a vacuum cleaner, which charged at an inexpensive price.
- Moreover, the auxiliary power supply device receives electricity for charging from a power supply source at a relatively inexpensive price in communication with an energy management system, and then, the charged power is preferentially used for a vacuum cleaner. Therefore, the vacuum cleaner operates at an inexpensive price.
- Furthermore, when such an auxiliary power supply device is used, wasted power is reduced. Thus, related industries may be developed and also environmental pollution caused by generating electricity may be reduced.
- While, this disclosure has been directed to a vacuum cleaner, one skilled in the art would readily appreciate that the invention is not limited to vacuum cleaners. Rather, the invention may be used in other appliances such as washing machines, dryers, dishwashers, airconditioners, fans, humidifiers, dehumidifiers, TVs, video players, audio players, and the like. Thus, the disclosure directed to vacuum cleaners should be understood as an example of how the invention may be used, and should not be construed as a limitation.
