Abstract

A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.

First claim

The invention claimed is:

1. An electric working machine comprising:
a motor configured to drive a tool for processing a workpiece;
a communicator configured to wirelessly communicate with a dust collector; and
a controller configured to transmit a registration request and an identification information via the communicator, the registration request requesting the dust collector to register the identification information therein, and the identification information being specific to the electric working machine,
wherein the controller is configured to transmit, when the motor is stopped, the registration request and the identification information.

2. The electric working machine according to claim 1 , further comprising a switch circuit configured to input a registration command, the registration command being a command to register the identification information in the dust collector,
wherein the controller is configured to determine, when the motor is stopped, whether the registration command has been input from the switch circuit, and
wherein the controller is further configured to transmit the registration request and the identification information via the communicator in response to a determination by the controller that the registration command has been input.

3. The electric working machine according to claim 1 , further comprising an operation detector configured to detect a drive state of the motor,
wherein the controller is configured to determine via the operation detector whether the motor is stopped.

4. The electric working machine according to claim 3 , further comprising a drive circuit configured to drive the motor,
wherein the operation detector is configured to detect the drive state of the motor based on an electric current flowing through a power supply path to the drive circuit.

5. A system comprising:
an electric working machine including:
a motor configured to drive a tool for processing a workpiece;
a first communicator configured to wirelessly communicate with a dust collector; and
a first controller configured to transmit a registration request and an identification information via the first communicator, the registration request requesting the dust collector to register the identification information therein, and the identification information being specific to the electric working machine; and
the dust collector including:
a dust collection portion configured to suck dust through a dust collection hose;
a second communicator configured to wirelessly communicate with the electric working machine;
a memory; and
a second controller configured to store the identification information in the memory in response to reception of the registration request and the identification information via the second communicator,
wherein the first controller is configured to transmit, when the motor is stopped, the registration request and the identification information.

6. The system according to claim 5 ,
wherein the electric working machine further includes a switch circuit configured to input a registration command, the registration command being a command to register the identification information in the dust collector,
wherein the first controller is configured to determine, when the motor is stopped, whether the registration command has been input from the switch circuit, and
wherein the first controller is further configured to transmit the registration request and the identification information via the first communicator in response to a determination by the first controller that the registration command has been input.

7. The dust collector according to claim 5 ,
wherein the second controller is configured to determine, in response to reception of the registration request, whether the identification information has been received,
wherein the second controller is configured to store, in response to a determination by the second controller that the identification information has been received, the identification information in the memory, and
wherein the second controller is further configured to notify via a notification portion, in response to a determination by the second controller that the identification information has not been received, that the identification information has not been received.

8. The dust collector according to claim 5 ,
wherein the second controller is configured to notify via a notification portion, in response to the second controller storing the identification information in the memory, a completion of storing the identification information.

9. A method for registering an identification information of an electric working machine in a dust collector, comprising:
inputting a registration command in the electric working machine;
determining, when a motor of the electric working machine is stopped, whether the registration command has been input;
transmitting a registration request and the identification information to the dust collector in response to a determination that the motor is stopped, the registration request requesting the dust collector to register the identification information in the dust collector; and
storing the identification information in a memory of the dust collector in response to reception of the registration request by the dust collector.

10. The method according to claim 9 , further comprising:
determining, in response to reception of the registration request by the dust collector, whether the dust collector has received the identification information; and
notifying, in response to a determination that the dust collector has not received the identification information, a failure of reception of the identification information.

11. The method according to claim 9 , further comprising notifying, in response to storing the identification information in the memory, a completion of storing the identification information in the memory.
