Claims

[Claims for Utility Model Registration] A working machine 2 and a cooling fan 3 are arranged in this order above the vertical axis engine 1, and the cylinder 6 of the vertical axis engine 1 is
and cylinder head 7 with cylinder cooling air cover 8
The work equipment 2 is covered with a work equipment cooling air cover 9, and a cylinder cooling air inlet 10 is opened in the lower part of the cylinder cooling air cover 8, and a communication port 11 is opened in the lower part of the work equipment cooling air cover 9. A vertical shaft is configured such that a work equipment cooling air inlet 12 is opened at the lower part of the work equipment cooling air cover 9, and the upper part thereof is communicated with the air intake chamber 13 of the cooling fan 3 through the air intake port 14. In a forced air cooling system for an engine working machine, most of the lower part of the working machine cooling air cover 9 in the circumferential direction is closed, and the remaining part is provided with a working machine cooling air inlet 12 on the crankcase 1 of the vertical axis engine 1.
The upper wall surface 16 of the working machine cooling air inlet 12 is formed in an upwardly sloping shape so that the upper wall surface 16 of the working machine cooling air inlet 12 faces a part of the circumferential side of the crankcase 15. The cooling air for the work equipment is concentrated on a part of the circumferential side and sucked into the work equipment cooling air inlet 12, and this work equipment cooling air is guided by the inclined entrance upper wall surface 16 and flows smoothly into the work equipment cooling air cover 9. A forced air cooling device for a vertical shaft engine working machine, characterized in that it is configured to
