Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling storage cabinet in which an opening communicating with the interior of the cabinet is formed in a top surface and a cold storage container is detachably provided so as to close the opening.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Utility Model Publication No. 3-30793 (F25D23 / 06), a cooling storage of this kind has a top surface of a main body made of a heat-insulating box as a workbench, and a sandwich is adjusted there. I am able to process the food. In this case, the above-mentioned food (foodstuff) is stored in the inside of the heat-insulated box to be refrigerated, but an opening communicating with the inside of the workbench is formed in the workbench, and this opening should be closed. A cold storage container is detachably installed in the container, and in addition to liquids such as water and milk, food items such as washed lettuce that are used immediately are stored in the container.

This cold storage container is opened upward on the workbench, but most of it enters the chamber through the opening. Therefore, since the side wall and the bottom wall of the cold insulation container are exposed to the cold air in the refrigerator, the food in the cold insulation container is cooled via the side wall and the bottom wall of the cold cold insulation container.

[0004]

However, when the cold insulating container is not used, the opening remains open. Therefore, when the cold storage container is not used conventionally, the lid is placed on the opening from the outside of the refrigerator to close the lid. However, the operation for covering the lid becomes necessary and the operation becomes complicated, and the lid is closed. Sometimes I forget. Further, there is a problem that the cooling efficiency of the inside of the refrigerator is remarkably lowered because the heat loss due to the outflow of cold air from the gap around the lid and the invasion of heat from the outside through the lid increases. Further, since the lid is strongly cooled by the cold air in the refrigerator, there is a problem that the dew condensation on the lid surface becomes remarkable and the workbench around the lid is soiled.

The present invention has been made in order to solve the above-mentioned conventional technical problems, and provides a cooling storage which can reduce heat loss from the opening of the top surface without impairing operability. The purpose is to provide.

[0006]

According to a first aspect of the present invention, there is provided a cooling storage cabinet, which is formed on a top surface of a heat insulating box and has an opening communicating with the interior of the storage box and a detachable opening so as to close the opening from the outside. A cold container, a closing member that opens and closes the opening from the inside of the refrigerator, and a biasing unit that constantly biases the closing member in the closing direction, and the cold container is attached to the opening. In this state, the closing member is opened against the biasing means.

The cooling storage according to the second aspect of the present invention includes an opening formed in the top surface of the heat insulating box and communicating with the inside of the storage box, and a cold storage container detachably provided so as to close the opening from the outside of the storage. The cooling container is provided with a closing member that opens and closes the opening from the inside of the refrigerator so as to be openable and closable, a biasing unit that biases the closing member in a direction to always close it, and a discharge port that discharges cool air into the inside of the refrigerator. While being attached to the opening, the closing member is pushed down against the biasing means, and in this state, the closing member is inclined so that the discharge port side is low.

[0008]

According to the cooling storage of the present invention, the closing member for opening and closing the opening formed in the top surface from the inside of the storage is provided, and the closing member is always biased by the biasing means. Therefore, even when the cold insulating container is not used, the opening is automatically closed by the closing member from the inside of the refrigerator. Therefore, the heat loss from the opening can be reduced without impairing the operability, and the dew condensation on the lid can be reduced even when the lid is used.

On the other hand, the closing member is opened against the biasing means by attaching the cold insulation container to the opening, whereby the cold air in the refrigerator is circulated around the cold insulation container. Can be cooled without any trouble and the operability can be improved.

In particular, according to the cooling storage of the invention of claim 2, the closing member is pushed down by attaching the cold insulation container to the opening, and in this state, the closing member is inclined so that the cold air discharge port side is inclined low. The cool air discharged from the discharge port is smoothly guided around the cool container by the inclination of the closing member. Therefore, the cooling effect of the cold insulation container can be improved.

On the other hand, the upper part of the heat insulating box 4 is projected to one side, and the cooling chamber 11 communicating with the inside 6 is provided therein.
The cooling chamber 11 is provided with a cooler 12 and a blower 13 which form a refrigerant circuit of the cooling device.
The cooling chamber 11 and the interior 6 are partitioned by a partition plate 14, and the air outlet 16 and the suction port 1 are provided above and below the partition plate 14.
7 are formed. On the lower surface of the top wall 4B of the heat insulating box 4,
A duct 19 extending from the vicinity of the air outlet 16 in the direction of the opening 4A is attached, one end of the duct 19 faces the air outlet 16, and the other end on the side of the opening 4A is the outlet 2.
It is supposed to be 1.

A machine room 22 is formed on the side of the heat insulating box 4 located below the cooling chamber 11, and a compressor forming a refrigerant circuit of a cooling device together with the cooler 11 therein. Condensing unit 23 including a condenser and a condenser
Is installed. And the front of this machine room 22 is
A panel 26 having a grill 24 is openably and closably closed.

On the other hand, a closing member 31 is attached to the lower surface of the ceiling wall 4B at a portion corresponding to the opening 4A of the heat insulating box 4. The closing member 31 has a shallow container shape and has a size larger than the cross-sectional area of the opening 4A. Also,
The closing member 31 is rotatably attached to the lower surface of the ceiling wall 4A by a hinge 32 at the upper end of the portion located on the side opposite to the duct 19, whereby the closing member 31 is opened.
A is closed from the inside 6 side so that it can be freely opened and closed. Further, a coil spring 33 as an urging means is attached between the portion of the closing member 31 located on the duct 19 side and the top wall 4B. The coil spring 33 constantly exerts an elastic force in a contracting direction, whereby the closing member 31 is constantly urged in a direction to close the opening 8A, and when the cold insulating container 2 does not exist, the opening 8A is opened from the inside 6 side. It's closed.

The cold insulation container 2 is formed of a stainless steel plate having good heat conductivity into a container shape having a circular cross section, has a bottom wall 2A and a side wall 2B and opens upward as shown in FIG. A flange 2C bent outward is formed on the periphery of the. The diameter of the side wall 2B of the cold insulating container 2 is smaller than the opening 8A of the top table 8 and sufficiently smaller than the opening 4A of the heat insulating box 4, and the cold insulating container 2 is provided.
The flange 2C has a dimension protruding outward from the flange 8B of the top table 8. The lid 3 is also made of a stainless steel plate and has a diameter larger than that of the opening 8A.

When the condensing unit 23 and the blower 13 are operated with the above-mentioned structure, the cool air that has exchanged heat with the cooler 12 is blown out from the blowout port 16, and the cold air is blown out, as shown in FIGS.
As shown by the arrow, the gas is discharged from the discharge port 21 into the inside 6 through the duct 19. Then, after circulating inside the chamber 6 to cool it, it returns from the suction port 17 to the cooling chamber 11. As a result, the food stored in the interior 6 is cooled and stored at a predetermined temperature.

In this state, when the cold insulation container 2 is inserted into the opening 8A, the bottom wall 2A of the cold insulation container 2 comes into contact with the closing member 31 before long. Then, when the cold storage container 2 is further inserted,
The closing member 31 is rotated counterclockwise in FIG. 5 around the hinge 32 against the coil spring 33, and is pushed down so that the discharge port 21 side is inclined low. As a result, the opening 4A
Is opened, and the passage 9 and the inside 6 are communicated with each other. Further, the flange 2C of the cold insulation container 2 is the flange 8 of the top table 8.
It is placed on B and closes the opening 8A from the outside of the refrigerator, and the bottom wall 2A of the cold insulating container 2 enters the inside of the refrigerator 6 and the side wall 2B.
A space is formed between the and the passage 9.

As a result, the cold insulation container 2 is attached to the opening 8A. By opening the opening 4A, the cold air in the cold storage 6 can be circulated around the cold insulation container 2, so that the cold insulation container 2 can be circulated. The water, milk, foodstuffs, etc. stored therein are cooled from the bottom wall 2A and the side wall 2B which have been cooled to a low temperature. In particular, in this state, the closing member 31 is
Since the first side is inclined low, the cool air discharged from the discharge port 21 is smoothly guided to the periphery of the cold insulation container 2 as shown by the arrow in FIG. Therefore, the cooling effect of the cold insulation container 2 is improved. Further, since the closing member 31 is opened only by inserting the cold insulation container 2 into the opening 8A, operability is not impaired. The lid 3 is placed on the flange 2C of the cold insulation container 2 to close the opening.

Next, when the cold insulation container 2 is not used,
The cold insulation container 2 is lifted from the state of FIG. 4 or FIG. 5 and pulled out from the opening 8A. When the cold insulation container 2 is no longer present in the opening 8A, the coil spring 33 is constantly closed as described above.
Since the closing member 31 is urged in the closing direction, the closing member 31 is rotated clockwise around the hinge 32 in FIG. 5, and the opening 8A (the passage 9 or the opening 4A) is moved to the inside 6 side as shown in FIG. Block from. Then, the lid 3 is placed on the flange 8B and the opening 8A is closed.

As described above, when the cold insulation container 2 is not used, the closing member 31 closes the opening 8A from the inside 6 side of the refrigerator, so that cold air flows out from the gap around the lid 3 and the lid 3 is interposed. It becomes possible to reduce the heat loss due to the invasion of heat from the outside, and the cooling efficiency of the inside 6 can be remarkably improved. Further, since the dew condensation on the lid 3 can be reduced, the top table 8 around the opening 8A can be prevented from being contaminated. In addition, the coil spring 33
The opening 8A is automatically closed from the inside 6 side by the closing member 31.
The operability is not impaired because it is blocked by.

The cold insulation container 2 can be used alone even when it is not attached to the opening 8A, and even in that case, the opening of the cold insulation container 2 can be opened and closed by the lid 3. Further, in the embodiment, when the cold insulation container 2 is not used,
Although the lid 3 is placed on the flange 8B, the present invention is not limited to this, and the opening 8A can be closed from the inside 6 by using only the closing member 31 without using the lid 3 to sufficiently eliminate the outflow of cold air. It goes without saying that you can do it. Further, although the coil spring is used as the biasing means in the embodiment, the invention is not limited to this, and
It may be a leaf spring or the like.

[0024]

As described above in detail, according to the present invention, a closing member for opening and closing the opening formed in the top surface portion so as to be openable and closable from the inside of the refrigerator is provided, and the closing member is always biased by the biasing means. Therefore, even if the cold insulating container is not used, the opening is automatically closed by the closing member from the inside of the refrigerator. Therefore, the heat loss from the opening can be reduced without impairing the operability, and the dew condensation on the lid can be reduced even when the lid is used.

On the other hand, the closing member is opened against the biasing means by attaching the cold insulation container to the opening, whereby the cold air in the refrigerator is circulated around the cold insulation container, so that the cold insulation container is circulated. Can be cooled without any trouble and the operability can be improved.

In particular, according to the second aspect of the invention, the closing member is pushed down by attaching the cold insulation container to the opening, and in this state, the closing member is inclined so that the cool air discharge side is inclined low. The discharged cool air is smoothly guided around the cool container by the inclination of the closing member. Therefore, the cooling effect of the cold insulation container can be improved.
