Problems solved by technology

However, in the case of a lawn mower with such a configuration, the rotational speed may become too high due to the user's operation state of the trigger switch, and conversely, the rotational speed may be too low to properly remove the entanglement on the cutting surface. blade of grass

Embodiment Construction

[0023] Hereinafter, preferred embodiments of the present invention will be described based on the drawings. Such as figure 1 As shown, the rechargeable lawnmower 1 of this embodiment includes a long handle pipe 2 , a control unit 3 , a cutting blade 4 , a motor unit 6 , a battery 7 , and a handle 8 .

[0024] The long-handled tube 2 is formed in the shape of a hollow rod having a predetermined length. A control unit 3 and a battery 7 are provided on one end side of the long handle tube 2 , and a motor unit 6 and a cutting blade 4 are provided on the other end side. On the other end side of the long-handled pipe 2, a cover 5 for preventing grass and the like cut by the cutting blade 4 from flying toward the user is provided.

[0025] The motor unit 6 is equipped with a motor 20 for rotationally driving the cutting blade 4 (refer to figure 2 ), a gear mechanism (not shown) for transmitting the rotational driving force of the motor 20 to the cutting blade 4, and the like. In...

Abstract

The present invention provides an electric lawn mower capable of effectively removing grass tangled around a cutting blade while suppressing wasteful power consumption. By operating the dial (13), the user can continuously or step by step adjust the prescribed control target value for controlling the motor (20). When the operation switch (12) is turned on, when the rotation direction is set to the forward rotation direction by the forward and reverse switching lever (14), the microcomputer (21) controls the When energizing the motor, when the rotation direction is set to the reverse direction by the forward and reverse switching lever (14), regardless of the control target value set by the dial (13), it is based on a preset constant reverse rotation. The target value is controlled to control energization to the motor (20).

Description

technical field [0001] The present invention relates to an electric lawn mower operated by a motor. Background technique [0002] There is known a lawnmower in which the above-mentioned lawnmowing mechanism includes a motor driven by a DC power supply, and the cutting blade is driven and rotated by the motor. As such a lawnmower, there is a lawnmower capable of switching the rotation direction of the motor (and thus the rotation direction of the cutting blade) to the forward direction of the rotation direction for mowing grass, and for removing Any rotation direction of the reverse direction of the rotation direction of the grass wound around a cutting blade (for example, refer patent document 1.). [0003] The lawn mowing mechanism described in Patent Document 1 is provided with a switching unit, and the direction of energization from the DC power supply to the motor can be switched by the switching unit to switch the direction of rotation. [0004] Patent Document 1: Jap...
