Description

Detailed Description of the Invention [Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling storage box having an opening formed in the top of a heat insulating box, and a cold storage container detachably provided in the opening.

[0002]

2. Description of the Related Art Conventionally, a cooling storage called a pizza station installed in a kitchen such as a home delivery pizza store is disclosed in, for example, Japanese Patent Laid-Open No. 1-263843 (F25D23 / 00).
As shown in Fig. 1, a workbench is formed on the top surface of the top wall of the heat insulation box defining the first cooling chamber, an opening is formed in the rear part of the top wall, and the first cooling chamber is formed above this opening. By installing a heat insulating protruding wall body (which becomes a part of the heat insulating box) of the upper and lower surfaces that defines a second cooling chamber communicating with the cold storage container and detachably accommodates the cold storage container, a horizontal commercial refrigerator is formed. ing.

A machine room for installing a compressor of a cooling device and the like is formed on the left side of the heat insulating box, and the heat insulating protruding wall body extends up to the upper side of the machine room to accommodate many types of toppings. It is extended and configured to hold a large number of cold storage containers. A cooler of the cooling device and a blower are attached to the left side of the first cooling chamber of the heat insulating box, and a duct is attached to the lower part of the cool container to guide the cool air discharged from the blower to the lower part of the cool container. It was configured.

[0004]

As described above, in the conventional cooling store, the cool air discharged from the blower is guided to the lower side of the cool container by the duct, but the heat insulating protruding wall body protrudes to the machine room side. Due to this, the duct does not exist below the cold insulation container on the machine room side, so that there is a problem that it becomes difficult for cold air to flow to the cold insulation container side at this portion, resulting in insufficient cooling.

Further, since the front surface of the machine room was closed by a panel provided with a grill, this panel was lined up with a door which closed the front opening of the first cooling chamber. On the other hand, adjustment work such as pizza topping is done on the workbench,
Due to the presence of the panel on the front side, the number of walks during work increased and work efficiency declined. Further, in the above publication, the machine room is on the left side of the heat insulation box, but depending on the kitchen layout, it may be desired to set it on the right side.Therefore, in order to meet such a request, the manufacturer selects the model of the left machine room and the right machine room. It had to be manufactured separately.

Further, in any case, the ventilation to the machine room is performed by sucking the outside air from the front grill and discharging it to the rear or side, but in a narrow kitchen, the left and right sides of the cooling storage and In some cases, the back surface may be completely covered with a wall, and in such a case, there is a problem that the exhaust performance from the machine room deteriorates and the cooling capacity decreases.

The present invention has been made in order to solve the above-mentioned conventional technical problems, and a cooling storage container capable of uniformly cooling the entire cold insulation containers arranged in parallel at the opening of the top of the heat insulating box. The purpose is to provide.

[0008]

The cooling storage of the present invention comprises:
A storage chamber that opens to the front is formed in the heat insulating box, and the front opening of this storage chamber is closed by a door so that it can be opened and closed, and an opening is formed in the top of the heat insulating box, and a plurality of openings are formed in this opening. And a cooler of a cooling device provided at the center of the top of the storage chamber, and a blower for circulating the cool air cooled by the cooler in the storage chamber. ,
A dew receiving plate provided below each cold insulation container, and an introducing portion formed at a position corresponding to the cooler of the dew receiving plate and introducing a part of the cool air discharged from the blower to the cold insulation container side. It is equipped with.

In the cooling storage according to the second aspect of the present invention, a machine room communicating with the outside is formed across the left and right in the lower rear part of the heat insulating box, and a compressor of the cooling device and a condenser are provided in the machine room. A fan and a blower for a condenser are installed side by side.

Further, according to the cooling storage of the invention of claim 3, the above-mentioned cooling box is mounted on both sides of the heat-insulating box body with the outer plates at predetermined intervals communicating with the machine room, and at the side of the door. An intake port and an exhaust port communicating with each of the above-mentioned intervals are formed on the front surface of each exterior plate.

[0011]

According to the cooling storage of the present invention, the cooler of the cooling device and the blower for circulating the cool air cooled by the cooler in the storage chamber are provided at the center of the top of the storage chamber.
Since the dew receiving plate is provided below each cold insulating container, and the introduction portion for introducing a part of the cool air discharged from the blower to the cold insulating container side is formed at a position corresponding to the cooler of the dew receiving plate, The cool air introduced from the introduction part is smoothly and uniformly guided around each cold container by the dew receiving plate.

Therefore, even when a large number of cold containers are arranged side by side, the food or the like in each cold container can be uniformly and stably cooled and stored. Also, since the dew condensation water dropped from the cold storage container is received by the dew receiving plate,
It is also prevented that foodstuffs stored in the storage room are flooded.

Further, according to the cooling storage of the invention of claim 2, in addition to the above, a machine room communicating with the outside is formed in the lower rear part of the heat insulating box across the left and right, and the compression of the cooling device is provided in the machine room. Since the machine, the condenser and the blower for the condenser are installed side by side, the ineffective space in front of the machine room when the machine room is formed on the side of the heat insulating box as in the past is eliminated, and the front of the cooling storage is almost a door. It is possible to reduce the number of walks during work in the kitchen and improve work efficiency.

In particular, since it is not necessary to manufacture products of various models having different machine room positions as in the conventional case, productivity can be improved and cost can be reduced.

Further, according to the cooling storage of the invention of claim 3, in addition to the above, exterior plates are attached to both sides of the heat insulating box at predetermined intervals communicating with the machine room, and at the side of the door. Since the intake port and the exhaust port communicating with each of the intervals are formed on the front surface of each exterior plate located on one side,
Even if the left and right side surfaces and the back surface of the cooling storage are all closed with walls, and also in the case where the outside air is sucked in from the front side of the intake port on the front surface of one of the exterior plates, and the air is passed through the machine room through the gap,
It is possible to discharge the gas through the space again and forward from the exhaust port on the front surface of the other exterior plate.

Therefore, even under such adverse conditions, it is possible to maintain the ventilation performance of the machine room and prevent the cooling capacity from decreasing. Further, since the intake port and the exhaust port are separated from each other, the occurrence of a so-called short circuit of the outside air ventilated in the machine room can be eliminated.
