Description

[Detailed Description of the Invention] The present invention relates to a product storage such as a showcase that stores and cools or heats products.

In this type of product storage, there is usually a storage chamber in the upper part of the main body and a machine room for cooling or heating the storage chamber in the lower part, and a double door is installed in the front opening of the storage chamber. In the case where the storage room is opened, a central pillar is installed at the front of the storage room, located inside the joint between the doors on both sides.

In that case, the insulation of the center column is not sufficient, so when the center column is used in high humidity, dew forms on the surface of the center column, flows down in the form of droplets, and flows into the machine room, staining the floor surface or entering the machine room. This had the disadvantage of causing rust.

The present invention is an attempt to improve these points, and the dew on the surface of the central column installed in front of the storage chamber is removed through the dew inlet hole into the machine room located below the storage chamber. The dew is introduced into the dew receiving tray, and the purpose is to perform dew treatment well and to prevent cold air or moisture inside the storage room from leaking to the outside through the dew introduction hole.

In addition, in the present invention, a storage chamber is formed in the upper part and a machine room for cooling or heating the storage chamber is formed in the lower part through a partition frame, and a double door is provided at the front opening of the storage chamber. A main body, a middle pillar erected at the front of the storage chamber of the main body, a dew inlet hole formed at a lower position of the middle pillar from an outer side to an inner side of the middle pillar, a dew receptor provided in the introduction hole over the inside and outside of the central column, having an open top surface and having an upper edge of the inner rear wall lower than the upper edge of the outer front wall and higher than the upper edge of the dew introduction hole; A dew conduit passage that receives dew overflowing from the upper edge of the rear wall inside the dew receiver and guides it downward through the partition frame, and a dew conduit passage that communicates with the lower part of the dew conduit passage and is provided in the machine room. It is characterized by being equipped with a dew pan.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a main body made of a heat-insulating box with an open front. Inside this main body 1, a storage chamber 3 is formed in the upper part and a machine room 4 is formed in the lower part through a partition frame 2. A channel-shaped center column 5 is erected in the section, and a double-door door 6 having double-layer transparent glass is attached to the front opening of the storage chamber 3 so as to be openable and closable, located in front of the center column 5. It is being

In addition, a product storage column 7 is installed in the storage room 3, and a cooling device 8 such as a compressor or a container that constitutes a refrigeration cycle is installed in the machine room 4. Products (not shown) stored in the storage room 3 are cooled by a cooling device 8 in the machine room 4.

A dew inlet hole 9 is formed at a lower position of the front wall of the middle pillar 5 from the outer side to the inner side of the front wall of the middle pillar 5, and the dew inlet hole 9 is connected to the front wall of the middle pillar 5. A dew receptor 18 is provided on the inside and outside of the container.

The dew receptacle 18 has an open upper surface, and the upper edge of the rear wall is lower than the upper edge of the front wall and higher than the upper edge of the dew introduction hole 9.

In addition, the bottom plate portion 3b of the inner box 3a constituting the storage chamber 3 is tilted downward from the outer peripheral side toward the center portion of the storage chamber 3, and the outlet portion 3C and the guide tube 10 provided below the center are A dew channel 12 is formed by the drain receptacle 11 and the drain receptacle 11, and a dew receptacle 14 provided in the machine room 4 is connected to the lower end of the drain receptacle 11 via a guide pipe 13.

Further, the partition frame 2 has a bottom plate portion 3b of the inner box 3a.
It is composed of a bottom plate part 3e of the outer box 3d in the storage chamber 3, and a heat insulating material 15 loaded between the two bottom plate parts 3b and 3e. A dew conduction groove 16 is formed that slopes downward from the outer circumferential side of the chamber 3 toward the drain receiver 11.

In such a structure, the surface of the middle pillar 5, that is, the middle pillar 5
The dew that has condensed on the outer surface of the front wall of the inner box 5 flows down the inner side of the inner column 5 through the dew receiver 18 of the dew introduction hole 9 while falling along the inner column 5, and flows down the inner side of the inner column 5 to the bottom plate of the inner box 3a. 3b, an outlet portion 3C, a dew conduit passage 12 consisting of a drain receptacle 11, and a guide pipe 13 to a dew receptacle 14 in the machine room 4.
flow down inside.

At this time, since the upper edge of the rear wall of the dew receptor 18 is lower than the upper edge of the front wall and higher than the upper edge of the dew introduction hole 9, the dew that has flowed into the dew receptor 18 is receptor 1
8, that is, in a state where the dew inlet hole 9 is filled, the storage chamber 3
This prevents cold air from leaking inside, and overflows from the upper edge of the rear wall portion of the dew container 18 and flows down onto the bottom plate portion 3b of the inner box 3a.

This prevents the cold air in the storage chamber 3 from leaking out of the refrigerator through the dew introduction hole 9.

In addition, in implementation, as shown in FIG. 4, a water-absorbing material 17 may be inserted into the dew receptor 18, and in this way, heat insulation between the inside and outside can be better achieved. .

In addition, in the above embodiment, the case where the inside of the storage chamber 3 is cooled has been described, but the present invention is not limited to this, and can also be applied to the case where the inside of the storage chamber 3 is heated. be.

According to the present invention, the dew condensed on the surface of the middle pillar in the front part of the storage chamber is introduced into the dew channel through the dew receiver of the dew inlet hole, and is also introduced into the dew catcher in the machine room below. It can be introduced smoothly, and thus dew treatment can be performed.

In addition, since the upper edge of the rear wall of the dew receptor is lower than the upper edge of the front wall and higher than the upper edge of the dew inlet hole, the dew that has flowed into the dew receptor will flow into the dew receptor, i.e. When the introduction hole is filled, the inside and outside of the storage chamber are sealed with liquid, thereby preventing cold air or moisture in the storage chamber from leaking through the dew introduction hole, and improving thermal efficiency.
