Heat insulation structure and image forming apparatus using the same
View Patent ↗A heat insulation structure includes: a duct member disposed above a fixing device that fixes developer onto a recording medium, through which air flows to be exhausted; a heat insulating member disposed between an upper side of the duct member and a lower side of a function member disposed above the duct member; and a gap forming member that forms a gap between the duct member and the heat insulation member in a vertical direction.
1. A heat insulation structure comprising:
a duct member disposed above a fixing device that fixes developer onto a recording medium, through which air flows to be exhausted;
a heat insulating member disposed between an upper side of the duct member and a lower side of a function member, the function member being disposed above the duct member; and
a gap forming member that forms a gap between the duct member and the heat insulation member in a vertical direction.
2. The heat insulation structure according to claim 1 , wherein a housing of the fixing device has a frame unit disposed above the duct member, and the gap forming member is a reinforcing member that joins both sides adjacent to each corner of the frame unit to reinforce the frame unit.
3. An image forming apparatus comprising:
an image forming unit that forms an image on a recording medium with developer;
a fixing device that is disposed downstream of the image forming unit in a transporting direction of a recording medium and fixes the developer onto the recording medium; and
a heat insulation structure, the heat insulation structure comprising;
a duct member disposed above a fixing device that fixes developer onto a recording medium, through which air flows to be exhausted;
a heat insulating member disposed between an upper side of the duct member and a lower side of a function member, the function member being disposed above the duct member; and
a gap forming member that forms a gap between the duct member and the heat insulation member in a vertical direction.
4. The image forming apparatus according to claim 3 , wherein a housing of the fixing device has a frame unit disposed above the duct member, and the gap forming member is a reinforcing member that joins both sides adjacent to each corner of the frame unit to reinforce the frame unit.
