Apparatus including freezing unit and projector including freezing unit

Abstract

There is disclosed an apparatus including a freezing unit in which the freezing unit can be operated without any trouble even when a main body rotates. A liquid crystal display projector (an apparatus) including a freezing unit having a refrigerant circuit constituted of a compressor, a radiator, a capillary tube (a pressure reducing unit), an evaporator and the like includes a rotator as a posture adjustment unit for adjusting the main body to a basic posture to maintain at least a lubricating performance of the compressor in accordance with a posture change of the main body. The rotator rotates to adjust the basic posture of the whole freezing unit, and a rotary shaft of this rotator is arranged in parallel with an optical axis of a light source on the same plane.

1 . An apparatus including a freezing unit which has a main body 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 being provided with posture adjustment means for adjusting the main body to a basic posture to maintain at least a lubricating performance of the compressor in accordance with a posture change of the main body.   
   
   
       2 . The apparatus including the freezing unit according to  claim 1 , wherein the posture adjustment means adjusts a basic posture to maintain a flow of a refrigerant in the refrigerant circuit. 
   
   
       3 . The apparatus including the freezing unit according to  claim 2 , wherein the posture adjustment means rotates to adjust the basic posture of the whole freezing unit, and the compressor, the radiator and the evaporator are arranged around a rotary shaft of the posture adjustment means. 
   
   
       4 . The apparatus including the freezing unit according to  claim 3 , wherein an inlet pipe and an outlet pipe of the evaporator are arranged along the rotary shaft of the posture adjustment means and arranged away from each other. 
   
   
       5 . The apparatus including the freezing unit according to  claim 1 , wherein the posture adjustment means adjusts the basic posture of the compressor only, and a refrigerant discharge pipe and a refrigerant suction pipe of the compressor are made of pipes having flexibility. 
   
   
       6 . A projector including a freezing unit, which is the apparatus according to any one of  claims 1  to  5 , comprising a main body including a light source, an optical element which processes light emitted from the light source in accordance with image information, and a projection lens which projects a projected image of the processed light onto a screen,
 wherein the posture adjustment means rotates to adjust a basic posture of the whole freezing unit or a compressor only, and a rotary shaft of the posture adjustment means is arranged in parallel with an optical axis of the light source on the same plane.
