Showcase with insulated wall separating the machine room from the cooling components
A showcase in which a cooling fan is provided on a cooling room side and a cooling fan motor is provided on a machine room side, wherein attaching and detaching the cooling fan can be facilitated. The showcase has a display room provided over an insulating wall and the machine room provided under the insulating wall. The machine room has a top plate, with a portion of the top plate being raised above a remaining portion of the top plate. A compressor and a condenser of a cooling unit are disposed in the machine room. The cooling room is provided in the insulating wall and an evaporator and the cooling fan of the cooling unit are disposed in the cooling room. The cooling fan motor is disposed in the machine room to drive the cooling fan. The cooling fan motor is detachably attached, from a lateral direction, to the top plate of the machine room at the raised portion.
1. A showcase in which a display room is provided over an insulating wall, comprising
an insulating wall;
a machine room provided under the insulating wall, the machine room having a top plate, covering a lower side of the insulating wall, with a portion of the top plate being raised above a remaining portion of the top plate;
a compressor and a condenser of a cooling unit disposed in the machine room;
a cooling room provided in the insulating wall; and
an evaporator and a cooling fan of the cooling unit disposed in the cooling room so that cold air heat-exchanged with the evaporator is circulated in the display room by the cooling fan,
the showcase further including a cooling fan motor disposed in the machine room to drive the cooling fan, the cooling fan motor being detachably attached to the top plate of the machine room from a lateral direction in a state that a rotating shaft of the cooling fan motor passes through the insulating wall into the cooling room, and
the cooling fan being detachably attached on the rotating shaft, wherein
the cooling fan motor is positioned at the raised portion of the top plate, and the cooling fan motor is attached from a lateral direction using attachment plate disposed on an inclined portion of the top plate, the inclined portion being disposed between the raised portion and the remaining portion of the top plate.
