Apparatus including freezing unit and projector including freezing unit

Abstract

There are disclosed an apparatus including a freezing unit capable of securely discharging drainage from an evaporator regardless of a posture change of a main body, and a projector including the freezing unit. A liquid crystal display projector (an apparatus) including a main body provided with a freezing unit having a refrigerant circuit constituted of at least a compressor, a radiator, a capillary tube (a pressure reducing unit) and an evaporator includes a tapered shape of a sealed path of a duct which surrounds the evaporator constituted in the whole region under the evaporator in a prospective posture change of the main body, a groove (a liquid receiving portion) formed in the center of the shape, and a wick (a discharge member) which discharges drainage received in this groove by use of a capillary force.

1 . An apparatus including a freezing unit in which a main body is provided with the freezing unit having a refrigerant circuit constituted of at least a compressor, a radiator, a pressure reducing unit and an evaporator, the apparatus comprising:
 a liquid receiving portion constituted in the whole region under the evaporator in a prospective posture change of the main body; and   a discharge member which discharges drainage received in the liquid receiving portion by use of a capillary force or a permeation force.   
   
   
       2 . The apparatus including the freezing unit according to  claim 1 , wherein the discharge member discharges, to the radiator, the drainage received in the liquid receiving portion. 
   
   
       3 . A projector including a freezing unit, which is the apparatus according to  claim 1  or  2 , comprising a main body including a light source, an optical element which processes light emitted from the light source in accordance with image information, a projection lens which projects a projected image of the processed light onto a screen, and a duct in which an evaporator is incorporated and which supplies, to the optical element, air subjected to heat exchange between the air and the evaporator,
 wherein the liquid receiving portion is constituted in an inner surface of the duct.
