DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of arranging a maintenance-free part connected to a water-cooled condenser or an air-cooled condenser constituting a refrigeration mechanism at the rear side of a refrigeration mechanism storage chamber and a compressor or the like. The present invention relates to an arrangement structure of a refrigeration mechanism in which equipment requiring maintenance work is arranged at a front side in a refrigeration mechanism storage room.

[0002]

2. Description of the Related Art An ice storage unit having an ice making mechanism and a freezing mechanism and an ice storage for storing ice cubes are mechanically and separately separated from each other, and an ice storage having a required capacity and an ice making unit are assembled. In addition, a stack-on type ice maker in which an ice maker unit is placed on the ice storage is known. In the ice making unit of the ice making machine, an ice making mechanism storage room and a refrigeration mechanism storage room are defined through a partition plate inside a rectangular parallelepiped housing, and the ice making mechanism is stored in the ice making mechanism storage room. In addition, a refrigeration mechanism including a compressor, an air-cooled condenser, a fan motor, a receiver tank, and the like is stored and arranged in the refrigeration mechanism storage chamber. Further, in the ice making machine, a water-cooled condenser is provided in consideration of a case where the refrigeration capacity may be reduced only by the air-cooled condenser when the ambient temperature rises, such as in summer, etc. By using the vessel together with the air-cooled condenser, the refrigeration capacity is prevented from being reduced.

[0003]

An air-cooled condenser, a fan motor, and a compressor constituting the refrigeration mechanism are arranged in this order from the front side to the rear side inside the refrigeration mechanism storage chamber. When the fan motor is rotated, the air-cooled condenser is configured to be cooled by the external air sucked from the air inlet formed on the front surface of the housing. In this case, the air-cooled condensing pressure regulating valve connected to the air-cooled condenser is necessarily disposed on the front side in the refrigeration mechanism storage chamber, and other devices such as the fan motor and the compressor constituting the refrigeration mechanism are air-cooled condensate. It was located behind the vessel. The air-cooled condensing pressure regulating valve hardly causes a failure even under severe use conditions, and if a failure occurs, it cannot be dealt with by simple repair at the site. On the other hand, fan motors, compressors, and the like are more likely to fail under severe operating conditions than the air-cooled condensing pressure regulating valve, but can be easily dealt with by on-site repair. For example, failures related to the fan motor include damage to the blades, disconnection of the motor, running out of oil in the bearings, and puncture of the condenser for the fa motor, and failures related to the compressor include disconnection of the motor and failure of the motor. Examples include seizure, poor contact of the bimetal thermo at the terminal portion, and disconnection of the crankcase heater. When such a failure occurs, it is possible to sufficiently cope with it by repairing each failure on site.

However, an air-cooled condensing pressure regulating valve, which conventionally does not require any maintenance work such as regular maintenance and inspection, and which cannot be dealt with when a failure occurs, is provided on the front side of the refrigeration mechanism storage chamber. On the other hand, equipment such as a fan motor and a compressor, which require regular maintenance and maintenance work and can be easily dealt with in the event of a failure, are located behind the air-cooled condenser. Had been arranged. Therefore, when performing maintenance work such as maintenance and inspection and repair of equipment such as a fan motor and a compressor from the front side of the housing, the work of removing and mounting the equipment while avoiding the air-cooled condenser and the air-cooled condensation pressure adjusting valve is performed. And the maintenance work is complicated and time-consuming. In addition, in a stack-on type ice making machine, a plurality of ice making units are stacked on top of an ice storage, and in this case, maintenance of equipment such as a fan motor and a compressor in the lower ice making unit is performed. It is pointed out that the work requires more time and labor.

[0005] The water-cooled water supply valve connected to the water-cooled condenser does not require regular maintenance work such as maintenance and inspection, like the air-cooled condensing pressure regulating valve. This equipment is also located on the front side of the refrigeration mechanism storage room, and this equipment is an efficient maintenance and inspection of equipment that requires maintenance work such as the fan motor and compressor. And hindered maintenance work such as repairs.
