Description

The present invention relates to a storage for storing a beverage in a cold state or storing food at a low temperature, and a storage facility for storing and storing the storage in a storage case or the like.

For example, a storage container that cools or keeps the inside of a conventional container that stores food and drink with a thermo module, for example, an insulated container for storing the stored article at a predetermined temperature, and a rear wall of the insulated container. A thermo module, a box-shaped inner heat sink box made of aluminum-based metal attached to the inner surface (use side heat exchange surface) of the thermo module, and the outer surface (heat source) of the thermo module And a heat sink for exhaust heat attached to the side heat exchange surface portion).
Then, the heat inside the box is moved to the outside surface by the thermo module through the inner box for absorbing heat, and the moved heat is released outside the box through the heat sink for heat dissipation. A cover having an intake port and an exhaust port is attached to the outside of the wall to form a ventilation path (outside chamber).
The cover is formed such that the rear corners of the left and right side surfaces of the outer chamber are inclined toward the center of the heat insulating container toward the rear, and the air inlet is provided on the inclined surface. In order to prevent dust from entering, a filter is provided. Moreover, the drain pan for receiving the drain which generate | occur | produces in a store | warehouse | chamber is installed under the heat insulation container (for example, refer patent document 1).

  In the storage described in Patent Document 1, dust in the air entering the outside chamber is trapped and accumulated by the filter, so that the filter is clogged, making it difficult for air to flow, and cooling capacity is reduced. In order to prevent the cooling capacity from being lowered, it is necessary to remove and clean the filter in order to remove the dust adhered and accumulated on the filter.

In the conventional storage, if the blower for circulating air is near the intake port, the flow velocity of the air passing through the intake port is increased, and it becomes easy to suck dust and the like.
In addition, if the exhaust port faces the upper surface or the oblique upper surface, foreign matter such as dust is likely to enter from the exhaust port, and foreign matter adheres to and accumulates on the heat sink fins, making it difficult for air to flow. There was a problem.
In addition, if the drain water discharge port protrudes from the bottom of the heat insulation container for the purpose of draining water, etc., or a screw or the like protrudes below the heat insulation container, there is a problem that it is difficult to insert the drain pan. It was.

The thermo module 10 is detachably fixed to the heat transfer block 11 from the rear side with screws or the like.

  The heat sink 12 is joined to the heat source side heat exchange surface portion 10 c of the thermo module 10 in a heat conductive manner. The heat sink 12 has a large number of aluminum fins 12a arranged in the vertical direction so that heat is exchanged by flowing air in the vertical direction from the lower side to the upper side.

  The back cover 13 has a structure that covers the heat sink 12 and is bent so as to surround the control board 31 on which the control circuit components are arranged. And while forming an air path, the whole back surface of the heat insulation container 1 is covered, and the chamber outside chamber is formed in the outer side of the rear wall of the heat insulation container.

The intake port 15 is provided so as to be positioned below the back cover 13 and below the heat sink 12 and to be positioned in substantially the same plane as the bottom surface of the heat insulating container 1.
Further, the exhaust port 16 is formed at a position away from the upper part of the heat sink 12 so as not to block the flow of air that has passed through the heat sink 12 on the rear upper part of the back cover 13 and substantially the same line as the heat sink 12.
An axial blower 20 is attached to the exhaust port 16 located at the top of the back cover 13 so as to exhaust air toward the back of the heat insulating container 1.

  The drain port 42 is provided at the bottom of the heat insulating container 1. And the drain water formed in the inner surface of the inner box 2 is guide | induced to the dish-shaped drain pan 41 arrange | positioned under the heat insulation container 1. FIG.
