The prior art described above is
Since the suction port is provided on the bottom surface of the casing, there is a problem in that dust and the like accumulated on the installation floor are sucked and the condenser cannot provide a predetermined ability. Further, even if the floor surface is cleaned at the time of installation, dust is always accumulated on the floor surface, and therefore, in the case of long-term use, the same problem will eventually occur.

As a method for solving this problem, it is possible to provide a filter on the lower surface of the condenser. However, even with this method, since the filter is the bottom surface of the device, the dirt of the filter cannot be visually confirmed, and
There is also a problem that the attaching and detaching work is troublesome. The present invention has been made in view of the above-mentioned problems, and prevents deterioration of the condensation capacity due to dust and the like, and cools the condenser well even if the exhaust passages cannot be secured on the upper surface, both side surfaces and the rear surface of the device. Provided is a refrigerating device for the purpose.
