Abstract

In an electric working machine, a scroll portion is provided at one of left and right sides of a machine body, and a relay member functioning as a power switch in which a power on/off key is removably inserted is provided at the other side of the machine body. The relay member is provided between a motor-driving battery and a control section so that the battery and control section can be electrically connected with each other by insertion, in the relay member, of the power on/off key and disconnected from each other by removal, from the relay member, of the power on/off key.

Claims

1. An electric lawn mower comprising:

a machine body section;

an electric motor mounted in said machine body section for being turned on by insertion, in a predetermined connection of said machine body section, of a power on/off key and turned off by removal, from said predetermined connection, of the power on/off key;

a cutter blade disposed within a cutter housing and rotatable via said electric motor to cut grass; and

a scroll portion disposed in said cutter housing so that clippings of the grass cut by said cutter blade are delivered through said scroll portion into a grass bag attached to a rear portion of said machine body section,

wherein said scroll portion is provided at one of left and right sides of said machine body section while said predetermined connection for removal insertion therein of the power on/off key is provided at the other of the left and right sides of said machine body section.

2. An electric lawn mower as claimed in claim 1 wherein said predetermined connection of said machine body section is provided integrally with a control section for controlling said electric motor.

3. An electric working machine comprising:

a machine body section;

a rechargeable battery mounted in said machine body section;

an electric motor rotatable by said battery;

a control section that controls said electric motor to allow said machine body section to travel and perform any of various functions; and

a relay member provided between said battery and said control section for electrical connection therebetween, wherein said battery and said control section can be electrically connected with each other by insertion, in said relay member, of a predetermined connecting member and disconnected from each other by removal, from said relay member, of the predetermined connecting member.

4. An electric working machine as claimed in claim 3 wherein said relay member includes a machine-side connecting portion integrally provided thereon for connection with a recharger to recharge said battery.

5. An electric working machine as claimed in claim 3 wherein said battery is a nickel- or lithium-based battery.

6. An electric working machine as claimed in claim 3 wherein said control section has a function for monitoring and controlling a temperature of said battery.

7. An electric working machine as claimed in claim 3 wherein said relay member includes a. positive terminal connected with a positive pole of said battery, and the positive terminal of said relay member functions also as a charging positive terminal for connecting a recharger with the positive pole of said battery.
