Description

  The present invention relates to a refrigeration apparatus that can take out food that has been stored at a low temperature after reheating or subsequently stored at a low temperature, and more particularly to an improved drainage structure for drainage generated in a heat exchange chamber.

Conventionally, as an example of this kind of refrigeration apparatus, the thing of the following patent document 1 is known. This includes a cart with a caster for storing a tray, and a fixed station that is equipped with a cooling means and a heating means to store the cart in a removable manner.
More specifically, the cart has a main body with a door made of a heat insulating box, divided into a left and right compartment with a heat insulating partition wall, and the tray passes through the partition wall. The trays are accommodated in a plurality of stages, and the hot food placement part of each tray is arranged on the side of the cold storage room, and the cold food placement part is arranged on the side of the cold storage room.
The station has a substantially box shape with the front surface opened to put in and out the above-described cart, and the ceiling wall has two heat exchange chambers arranged side by side in the horizontal direction, and the first heat exchange chamber is cooled. A cooling means comprising a vessel and a heating means comprising a heater are provided, and only the cooling means is provided in the second heat exchange chamber. When the cart is stored in the station, an air circulation path is formed between the first heat exchange chamber and the refrigerator compartment and between the second heat exchange chamber and the refrigerator compartment. Yes.

  As an example of use, in the evening of the previous day, hot and cold foods prepared for cooking are put on a tray and stored in a chilled storage in a freezer. The next morning, the trays are removed from the freezer, and each tray is stored in a plurality of stages across the cart's warm and cold rooms, and the cart is placed in the station. Initially, the cooling means is operated in both heat exchange chambers, and cold air is circulated and supplied to both the hot and cold rooms, so that both hot and cold foods placed on the tray are defrosted at low temperature. When the predetermined time elapses, the operation of the timer is switched from the cooling means to the operation of the heating means in the first heat exchange chamber. On the other hand, in the second heat exchange chamber, the cooling means is continuously operated. Thereby, the hot food thawed by circulating warm air in the warm room is reheated, while the set temperature in the refrigerator is lowered a little on the cold room side, and the cold food is continuously stored in the cold state. When the serving time is reached, the cart is withdrawn from the station, the tray is removed, and served for serving.

  Here, in each heat exchange chamber, a drain pan for receiving defrost water is disposed on the lower surface of the cooler. On the first heat exchange chamber side, since the heating operation is performed after the cooling operation, even if frost is formed on the cooler, the defrost water is defrosted because the warm air continues to pass through the cooler. It can be expected that the defrosted water stored in the tank is also evaporated and discarded by the heat of warm air. On the other hand, since only the cooling operation is basically performed on the second heat exchange chamber side, frosting gradually proceeds in the cooler, and therefore the defrosting operation is appropriately performed. The defrost water at this time can also be received by the drain pan, but in addition to the large amount, it cannot be expected to evaporate after it has been stored. In this case, it is immediately drained to the outside by the drain pipe connected to the drain pan. Means are taken.
