PURPOSE:To enable blowing or suction to be carried out freely in any required direction by a method wherein each of suction and blowing ports is arranged at four circumferential sides of a lower panel arranged at the lower part of a machine body, each of the suction and blowing ports is communicated with a blowing passage and at the same time several partition plates are variably arranged within the blowing passage. CONSTITUTION:A lower panel frame 6 is fitted and connected to a lower part of a machine body 1 in such a way that its vertical position may be freely adjusted and at the same time some suction and blowing ports 8... having a proper opening size are opened and formed at the four corners of a circumferential part of a lower surface panel 7. Several partition plates 9 are arranged within a blowing passage 11 in the suction and blowing ports 8 so as to divide and form it into a suction port 8a and a blowing port 8b. Air direction changing vanes 10 are movably attached in each of the ports. Either a blowing cylinder frame 13 or a lower surface panel 7 is attached to the machine body 1 in such a way that its position may be varied and rotatable. This is rotated or a partition position of the partition plate 9 can be freely varied, thereby a positional relation of the suction direction and blowing direction may easily be converted and selected. |
