Abstract
Description
図1は、本実施形態に係る作業車両100の一例を示す斜視図である。本実施形態においては、作業車両100がフォークリフト100であることとする。本実施形態において、フォークリフト100は、バッテリを動力源とするバッテリフォークリフトである。
図2は、本実施形態に係るヒータ装置1の一例を右側から見た側面図である。図3は、本実施形態に係るヒータ装置1の一例を右後方から見た斜視図である。図4は、本実施形態に係るヒータ装置1の一例を上方から見た斜視図である。図5は、本実施形態に係るヒータ装置1の一例を右前方から見た斜視図である。
次に、本実施形態に係るヒータ装置1の動作の一例について説明する。運転者は、ヒータ装置1の起動を希望する場合、ダッシュボード15に設けられているヒータ起動スイッチを操作して、ヒータ装置1を起動する。ヒータ起動スイッチが操作されることにより、電気ヒータ70に電流が供給され、ファン80の回転が開始される。本実施形態において、電気ヒータ70及びファン80は、動力源としてのバッテリから供給される電力により作動する。なお、電気ヒータ70及び80は、動力源とは別のバッテリから供給される電力により作動してもよい。
以上説明したように、本実施形態によれば、ヒータ装置1は、収容部材12のバッテリ室に収容されているバッテリから供給される電力により発熱する電気ヒータ70を有する。そのため、内燃機関が無くても、ヒータ装置1は、温風を発生可能である。したがって、バッテリフォークリフトにおいても、寒さに起因する運転者の不快感が緩和され、寒さに起因するフロントガラス19における着霜、着氷、及び結露が抑制される。
