Hereinafter, the control structure of the vacuum cleaner will be described.

10 is a block diagram showing the control structure of the vacuum cleaner 1 .

11 is an exemplary view illustrating buttons of a manipulation unit.

As shown in FIGS. 10 and 11 , the vacuum cleaner 1 is connected to the cleaning main body 20 and the cleaning main body 20 , and the intake brush 10 and the wet mop brush 1000 are provided to be interchangeable. ) is included. The vacuum cleaner 1 operates in the intake cleaning mode when the intake brush 10 is connected to the cleaning main body 20 , and operates in the water cleaning mode when the wet mop brush 1000 is connected to the cleaning main body 20 .

The cleaner main body 20 includes a processor 100 that performs processing of the operation of the vacuum cleaner 1 . The processor 100 includes one or more hardware processors implemented with a CPU, a chipset, a buffer, a circuit, etc. mounted on a printed circuit board, and may be implemented as a system on chip (SOC) depending on a design method. Alternatively, the processor 100 may be implemented as a microcontroller. The processor 100 identifies whether the suction brush 10 or the wet mop brush 1000 is connected to the cleaning main body 20 and executes a corresponding mode according to the identified result.

A method for the processor 100 to identify which one of the intake brush 10 and the wet mop brush 1000 is connected to the cleaning main body 20 may be applied in various ways. For example, the intake brush 10 has an intake brush terminal portion 11 , and the wet-cloth brush 1000 has a wet-cloth brush terminal portion 1500 . When the intake brush 10 or the wet mop brush 1000 is mounted on the suction pipe 40 (see FIG. 1), the intake brush terminal 11 or the wet mop brush terminal 1500 is connected to the cleaning main body 20 through the corresponding terminal provided in the suction pipe. ) is connected to Here, the specific terminal provided in the wet mop brush terminal unit 1500 has different electrical characteristics from the terminal provided in the intake brush terminal unit 11, and the processor 100 detects this and attaches the air intake brush 10 and the wet mop to the cleaning main body 20 by detecting this. It is possible to identify which of the brushes 1000 is connected. For example, the wet-mop brush terminal part 1500 includes a terminal connected to a resistance of a predetermined value, whereas the intake brush terminal part 11 can be designed not to include such a terminal. The processor 100 may detect the connection of this terminal.

For example, when it is identified that the intake brush 10 is connected to the cleaning main body 20 , the processor 100 operates the intake pump 200 in response to a user operation to perform intake cleaning using the intake brush 10 . do. On the other hand, when it is identified that the wet mop brush 1000 is connected to the cleaning main body 20, the processor 100 sprays water by operating the water spray pump 1150 in response to a user operation and operates the motor 1600. By rotating the rotating disk 1130, water cleaning is performed.

A separate button may be provided for the operation unit 90 on which a user operation is performed, depending on each cleaning mode, but the same button may be used in a different layout for each cleaning mode. Hereinafter, such an embodiment will be described.

The operation unit 90 includes, for example, a power button 91 and a pair of control buttons 92 . The power button 91 is a toggle button for switching between a turn-on state and a turn-off state, and a pair of control buttons 92 is a button set for level adjustment. Corresponding to which one of the intake brush 10 and the wet mop brush 1000 is connected to the cleaning main body 20 , the role of the button included in the operation unit 90 changes.

For example, in the intake cleaning mode in which the intake brush 10 is connected to the cleaning main body 20 , the processor 100 turns on or off the intake pump 200 in response to the operation of the power button 91 . In addition, the processor 100 adjusts the suction force at which the intake brush 10 sucks air by adjusting the pumping intensity of the intake pump 200 in response to the operation of the control button 92 .

On the other hand, when the wet mop brush 1000 is connected to the cleaning main body 20 in the water cleaning mode, the processor 100 turns on the motor 1600 and the water spray pump 1150 in response to the operation of the power button 91 or turn it off. Meanwhile, the processor 100 does not perform a specific operation in response to the manipulation of the control button 92 in the water cleaning mode.

As such, in response to a button input of the manipulation unit 90 , the processor 100 executes an operation designated to correspond to the current cleaning mode.
