Embodiment 1

[0038] figure 1 It is a schematic perspective view showing a projector as an embodiment of the device having a refrigeration unit of the present invention. The projector of this embodiment is provided with a light source 2, a uniform illumination optical system 3, a color separation optical system (not shown in the figure), an optical element 5, a projection lens 9 and a freezing unit 10 of the optical element 5 inside the main body 1. LCD projector P. The main body 1 is a flat frame made of a material with excellent heat dissipation performance, for example, magnesium. and, in figure 1 In order to illustrate the various devices provided inside the main body 1, the main body 1 is shown from above in a cutaway cross section.

[0039]The light source 2 is composed of a lamp 20 such as an ultra-high pressure mercury lamp, and a reflector 21 for emitting light (divergent light) diverged from the lamp forward. The light source 2 of the embodiment is constituted by attaching a r...

Embodiment 2

[0068] In addition, in the above-mentioned first embodiment, the entire refrigerating unit 10 is provided so as to be rotatable, but in the present invention, at least the basic posture of the compressor 12 can be maintained by the posture adjustment mechanism. Therefore, in this embodiment, an example of a configuration in which only the basic posture of the compressor 12 is maintained according to the posture change of the main body using the posture adjustment mechanism will be described. In addition, since the basic configuration, operation, etc. in this embodiment are the same as those of the liquid crystal projector P described in the above-mentioned embodiment, description thereof will be omitted, and only different configurations will be described.

[0069] The posture adjustment mechanism of this embodiment is constituted by a rotating shaft 60 arranged parallel to the lamp axis A (optical axis) of the light source 2 on the same plane. rotate. Specifically, the rotat...

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.

Description

technical field [0001] The present invention relates to a device with a refrigerating unit, wherein the refrigerating unit has a refrigerant circuit composed of a compressor, a radiator, a decompression device, and an evaporator; the present invention also relates to a projector having the refrigerating unit . Background technique [0002] Conventionally, a refrigeration unit having a refrigerant circuit including a compressor, a radiator, a decompression device, an evaporator, and the like is installed in various devices such as refrigerators, freezers, and air conditioners. Because these devices are usually fixed, an oil reservoir is formed in the lower part of the container of the compressor of the refrigeration unit, and the oil is stored by gravity, and the oil is extracted from the oil reservoir and supplied to the wear part (sliding part) [0003] (Patent Document 1). [0004] In addition, when using a refrigeration unit as a car air conditioner that adjusts the air...
