Abstract:
A drain up device comprises a drain pan (18) for storing drain water (DW), and a
drain pump (30) for sucking and discharging the drain water (DW) stored in the
drain pan (18). The drain pump (30) has an impeller member (32b1) for
sucking the drain water (DW). On the extension of the rotary shaft of the impeller
member (32b1), a rotary member (32b2) rotating to stir the
