Document Type and Number:
WIPO Patent Application WO/2023/053288
Kind Code:
A1
Abstract:
A fan unit (60) is arranged on the upper surface of a housing (50) and includes a fan, a frame member (66), and a support member. The frame member (66) is arranged so as to surround the outer periphery of an opening formed in the upper surface (50A) of the housing (50). The support member supports the fan above the opening while fixed to the frame member (66). A gap is formed between the lower edge of a first surface (66A) of the frame member (66) and the upper surface (50A) of the housing (50). A first closing member (70) is connected so as to be vertically slidable with respect to the first surface (66A) of the frame member (66). The first closing member (70) is configured so as to close the gap while in contact with the upper surface (50A) of the housing (50). At least one second closing member (90) is configured so as to be inserted into the interior of the frame member via the gap while the gap is exposed and thereby close the opening in the upper surface (50A) of the housing (50).
