Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to an automatic revolving shelf refrigerator in which a large number of shelves for placing food and other items inside the refrigerator can be rotated in circulation. This is an improved version of the blowout method.

[Conventional technology]

This type of automatic revolving shelf refrigerator was first developed in 1983.
It is publicly known from 43888 and 61-123374.

In addition, in other types of refrigerators and refrigerated storage cases, a type in which a cold air circulation duct equipped with a blower and a cooler is placed inside the refrigerator and cool air is blown out from the ceiling of the refrigerator is also available. It is publicly known in the publication No.

[The problem that the idea aims to solve]

However, in conventional automatic revolving shelf refrigerators, the third
As shown in the figure, a cooler 8 is installed on the ceiling side of the refrigerator body 1.
are arranged. Therefore, the ceiling space in the refrigerator interior 15 was not effectively utilized. That is, in the longitudinal side view of FIG. 3, when the shelves 2 were rotated in circulation in the refrigerator interior 15, triangular dead spaces D, D were created in front and behind the ceiling space. When the vertical height of the chamber interior 15 was kept constant, the overall height was further increased due to the presence of the cooler 8.

Further, since the cold air is blown out from the cooler 8 unevenly, the food on the shelf 2 near the air outlet 17 tends to become too cold.

Furthermore, conventionally, since the cooler 8 is located on the ceiling side, the refrigerator unit (condensing unit) is also generally installed on the upper part of the refrigerator body 1, which has the disadvantage that maintenance thereof is time-consuming. If the overall vibration isolation and strength were insufficient, noise problems such as resonance were likely to occur.

The present invention has been proposed to eliminate such conventional disadvantages.

The purpose of the present invention is to provide an automatic revolving shelf type refrigerator that makes effective use of the ceiling space inside the refrigerator and can uniformly control the freshness of food by using cold air blown from the ceiling side.

Another object of the present invention is to provide an automatic revolving shelf type refrigerator that is not subject to space restrictions during installation work and is easy to maintain.

[Means to solve the problem]

The present invention is based on the assumption that the refrigerator is an automatic revolving shelf type refrigerator in which a large number of shelves 2 are rotatably installed inside the refrigerator body 1. There are no particular limitations on the type or drive system for circulating and rotating the shelves 2.

In addition, the refrigerator body 1 has a cold air circulation duct 9 equipped with a blower 7 and a cooler 8, and this duct 9 is arranged along the vertical side wall of the refrigerator body 1 and is connected to a side duct portion 9a containing the cooler 8. and a ceiling duct section 9 that is arranged over the entire ceiling space within the refrigerator main body 1 and is connected to the side duct section 9a.
It consists of b. The duct wall 12 facing the interior 15 of the ceiling duct portion 9b includes a main wall portion 12a that is substantially parallel to the upper wall 11 of the refrigerator main body 1, and a main wall portion 12a that extends obliquely downward from both ends of this main wall portion 12a. Hem wall part 12
It is formed in the shape of a mountain having the points b and 12c.
Among these, one skirt wall 12b is connected to the duct wall 14 facing the inside 15 of the side duct section 9a, and the other skirt wall 12c is connected to the vertical side wall 3 on the side duct section 9a side. It is connected to the vertical side wall 16 of the refrigerator main body 1, and is connected to the ceiling duct part 9b.
The inside of the refrigerator is completely separated from the inside of the refrigerator by a duct wall 12. The main wall portion 12a of the duct wall 12
Also, a large number of cold air blowing holes 13 are provided all over the both skirt walls 12b and 12c.

The duct wall 12 completely partitions the interior of the ceiling duct part 9b and the interior 15 of the refrigerator where the shelves 2 rotate.
The opening ratio of the cold air blowing holes 13 in the duct wall 12 is adjusted in the direction of cold air flow in the ceiling duct part 9b so that the amount of cold air blown out from the duct wall 12 is almost uniform throughout. The upper and lower sides of P are changed.

[Effect]

The air inside the refrigerator 15 is transferred to the side duct section 9 by the blower 7.
After being sucked into the air cooler 8 and cooled by the cooler 8, it is pushed into the ceiling duct section 9b. Then, the cold air is blown out from the entire surface of the duct wall 12 of the ceiling duct portion 9b into the refrigerator interior 15 through the cold air blowing holes 13 without being biased.

The duct wall 12 is formed into a mountain shape having a main wall part 12a and skirt walls 12b and 12c at both ends thereof, and completely partitions the inside of the ceiling duct part 9b and the inside of the refrigerator 15. 12a and hem wall 12
A large number of cold air blow-off holes 13 are formed over the entire surface at b and 12c. Therefore, in the main wall 12a of the duct wall 12, cold air is blown out directly below the inside 15 of the refrigerator, and in both skirt walls 12b and 12c extending diagonally downward, the cold air is blown out toward the center of the inside 15 of the refrigerator. Cool the inside 15 uniformly.

[Effect of idea]

As explained above, although the present invention is an automatic rotating shelf type refrigerator, a cold air circulation duct 9 is provided inside the refrigerator body 1, and the cooler 8 is arranged in the side duct portion 9a of the duct 9. Therefore, the ceiling duct portion 9b of the duct 9 does not require vertical space, and the dead spaces D and D seen in the conventional example can be taken in so as to form a part of the ceiling duct portion 9b, and the duct wall 12 with the cold air blowing holes 13, In other words, inside 1
Since cold air can be blown out from the ceiling wall of No. 5,
This has the advantage that the cold air does not concentrate and directly blow onto the food on the shelf 2, allowing more severe temperature (freshness) control. In particular, the duct wall 12 is formed in a mountain shape having a main wall portion 12a substantially parallel to the ceiling wall 11 of the refrigerator main body 1, and skirt wall portions 12b and 12c extending diagonally downward from both ends of the main wall portion 12a. However, the inside of the ceiling duct part 9b is completely partitioned off from the inside of the refrigerator 15 by this duct wall 12.
The main wall portion 12a and both skirt wall portions 12b, 12
Cold air blow-off holes 13 are provided throughout the area c.
Therefore, the cold air guided into the ceiling duct section 9b,
In the main wall portion 12a, both hem portions 1 are located directly below the chamber interior 15.
At 2b and 12c, the air is blown out obliquely toward the center of the refrigerator interior 15, so that the interior 15 can be cooled uniformly without temperature unevenness.

In addition, unlike the conventional configuration in which the cooler 8 is arranged in the ceiling space, the vertical space for rotating the shelves 2 in the refrigerator interior 15 is effectively secured, and the overall height of the refrigerator body 1 is increased as much as possible. It can be kept small. Moreover, since the cooler 8 is provided in the side duct portion 9a, the refrigerator unit 1
0 does not need to be placed on the top of the refrigerator body 1, so as long as there is enough floor space for installation, it can be installed even in places where there is very little vertical installation space. Furthermore, since the refrigerator unit 10 can be placed below the refrigerator main body 1 or at a different location, it is also advantageous for maintenance.

〔Example〕

FIG. 2 shows the overall schematic configuration of the target automatic rotating shelf refrigerator, in which a large number of shelves 2 are supported in a horizontal position inside the refrigerator main body 1 and are installed so as to be able to circulate and rotate in the vertical direction. There is. A doorway 5 that is opened and closed by a shutter 4 is provided in the front wall 3 of the refrigerator body 1 between the left and right sides, and a loading table 6 is fixed to the bottom of the doorway 5 in a forward-protruding manner. When an arbitrary shelf 2 is designated and called up through the user interface, the shelf 2 rotates to the entrance 5 and stops, the shutter 4 is opened, and the food on the shelf 2 can be taken out from the entrance 5.

Thus, a cold air circulation duct 9 equipped with a blower 7 and a cooler 8 is installed in the upper part of the refrigerator body 1, and a refrigerator unit 10 for the cooler 8 is installed outside the front wall 3 and below the table 6. It is arranged.

In FIG. 1, the cold air circulation duct 9 includes a side duct section 9a arranged along the front wall 3, and a ceiling duct section arranged over the entire ceiling space inside the refrigerator body 1 and connected to the side duct section 9a. 9b
It consists of.

Among these, the ceiling duct part 9b is composed of the upper wall 11 of the refrigerator main body 1 and the duct wall 12 facing the upper wall 11 with a predetermined distance therebetween.

The duct wall 12 is made of a punching board in which a large number of cold air blow-off holes 13 are dotted over the entire surface, and includes a central main wall portion 12a that is parallel to the upper wall 11 in longitudinal side view, and a main wall portion 12a from the front and rear ends of the main wall portion 12a. It has a mountain shape with skirt walls 12b and 12c extending obliquely downward. A duct wall 14 whose front hem wall portion 12b faces the interior 15 of the side duct portion 9a
The rear hem wall 12c is connected to the rear wall 16 of the refrigerator main body 1, and the ceiling duct 9b is connected to the rear hem wall 12c.
The inside of the refrigerator is completely separated from the inside of the refrigerator by a duct wall 12. In other words, the duct wall 12 constitutes the ceiling wall of the refrigerator interior 15 in which the shelves 2 are housed, and the refrigerator body 1
The conventional triangular dead spaces D and D, which were created before and after the upper end of the inside, now serve as cold air passages.

Furthermore, a cooler 8 is provided in the side duct section 9a, and a blower 7 is arranged in a triangular space created at the joint between the side duct section 9a and the ceiling duct section 9b.

In such a case, the air inside the refrigerator 15 is sucked into the side duct section 9a by the blower 7, and the air is drawn into the cooler 8.
After being cooled down, it is pushed into the ceiling duct section 9b. Then, the duct wall 12 of the ceiling duct part 9b
Cold air blows out from the entire surface toward the ceiling space of the warehouse interior 15.

The opening ratio of the 13 groups of cold air blowing holes in the duct wall 12 can be adjusted in the cold air flow direction P in the ceiling duct part 9b by changing the hole diameter or the number of openings.
The upper side of is set smaller than the lower side. Therefore, by making the internal pressure of the ceiling duct part 9b higher than that of the inside 15 of the refrigerator and applying a predetermined static pressure, the amount of cold air blown from the duct wall 12 can be made equal to the upper side and the lower side in the cold air flow direction P. It is made to be as uniform as possible across the board.

[Another embodiment example]

The drive system for circulating and rotating the shelves 2 is not limited at all; for example, the doorways 5 may be provided on the front and rear walls 3 and 16 of the refrigerator body 1, respectively, or on two or more floors of a building. It may also be a form in which the refrigerator bodies 1 are arranged across the floor and entrances and exits 5 are provided on each floor.

The blower 7 may be provided on the side duct portion 9a side. Although the duct wall 14 of the side duct portion 9a and the duct wall 12 of the ceiling duct portion 9b are shown as separate bodies for convenience of explanation, both 12 and 14 may be formed by being bent in series.

The skirt wall portions 12b and 12c of the duct wall 12 of the ceiling duct portion 9b may have an arc shape instead of the inclined shape shown in the figure.

The side duct part 9a is connected to the front side wall 3 of the refrigerator main body 1.
It is not limited to this, and may be arranged inside the rear side wall 16 or the left and right side walls. It goes without saying that the refrigerator unit 10 may be placed anywhere below the refrigerator body 1.
