Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical rotary shelf in which a large number of storage shelves cyclically move along an endless circulation path having a vertical moving path, and particularly to drying and storing dishes, cooling foods and medicines. The present invention relates to a vertical rotating shelf with a heat exchanger used for storage.

2. Description of the Related Art As a vertical rotary shelf, an endless chain is formed by vertically extending a drive wheel and a driven wheel, which are vertically arranged in a box body, to form an endless circulation path having a vertical movement path. It is known that a plurality of storage shelves are supported so as to circulate through the storage shelves, and the storage shelves are moved to a delivery port by driving an endless chain. Such a vertical carousel has the advantage that many items can be stored in a small floor area, so it is used as a school lunch facility or a kitchen facility for drying and storing a large amount of tableware. Or refrigeration of large amounts of chemicals in hospitals
It is used for preservation. In a vertical rotary shelf used for drying or refrigerating, hot air or cold air is circulated in a storage chamber inside a box in which the storage shelves circulate.

In this type of vertical rotary shelf with a heat exchanger, a heat exchanger (including a refrigerator) for generating hot air or cold air is conventionally provided outside the storage chamber. (For example, Japanese Utility Model Laid-Open No. 2-125739)
reference).

[0004]

However, according to such a vertical rotary shelf with a heat exchanger , the heat exchanger forms a storage chamber.
It is placed on the outside of the box, and requires a large floor area for installation. For this reason, there is a problem that the advantage of the vertical rotary shelf that can store a large number of articles in a small floor area is impaired, and the advantage cannot be utilized to the maximum extent. Also, the heat loss will increase
There was a flaw.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view of a vertical rotary shelf with a heat exchanger according to an embodiment of the present invention, FIG. 2 is a schematic structural view thereof, and FIG. 3 is a front view of the relevant part.

This vertical rotary shelf itself is known, and an endless chain 4 is hung between a drive wheel 2 and a driven wheel 3 which are axially controlled above and below a box body 1 made of a heat insulating panel to move vertically. An endless circulation path having a path A is formed, and storage shelves 5 are provided with support arms 6 at a plurality of locations on the endless chain 4 at predetermined intervals.
6 and a guide arm 7 are hung and supported so as to be circulated and moved while always maintaining a horizontal posture, and each storage rack 5 is driven by an endless chain 4 so that each storage rack 5 is provided on the front side of the box 1.
It is supposed to be moved to. Tableware, chemicals, and other articles can be put into and taken out of the storage rack 5 through the cash slot 8.

As shown in FIGS. 2 and 3, the drive wheels 2 are provided at the left and right ends of a horizontal shaft 9 provided at the bottom of the box 1, and the drive wheels 3 are provided at the top of the box 1. Is installed,
One drive wheel 2 is connected to a drive motor 11 via a speed reduction mechanism 12. A guide frame 13 guides the traveling of an endless chain 4 which is stretched over a driving wheel 2 and a driven wheel 3 which correspond in the vertical direction.

The storage rack 5 supported by the endless chain 4 moves outside the endless circulation path, that is, outside the space S surrounded by the four front, rear, left and right guide frames 13. Therefore, the space S is a play space.
The heat exchanger 14 is installed in this space S via a pedestal 15. The heat exchanger 14 has a heat exchange tube built therein, and a steam inlet pipe 16 and a steam outlet pipe 17 which are arranged by inserting the box body 1 through the heat exchange tube are connected to each other. Further, the heat exchanger 14 has a downward facing hot air outlet 18, and a circulating air distribution duct 19 is connected to the upper inlet thereof. On the other hand, the blowers 21 and 22 are installed in the upper and lower two stages on the support base 20 attached to the outside of the box body 1,
The outlets of the blowers 21 and 22 have separate ducts 23,
It is connected to the circulating air distribution duct 19 via 24, and the perforated plate 2 such as punching metal is provided in the upper part of the box body 1.
6 is provided and is formed through the perforated plate 26.
The circulation duct 25 is connected to the circulation air passage 27, and the circulation duct 25 is connected to the inlets of the blowers 21 and 22.

In the above structure, when steam is supplied to the heat exchange tubes of the heat exchanger 14 and the blowers 21 and 22 are operated, the air distributed through the duct 23 and the circulating air distribution duct 19 enters the heat exchanger 14. , Becomes hot air and is blown downward from the heat exchanger 14 in the space S. This warm air is forcibly circulated from the space S into the inside of the box 1 as shown by the arrow in FIG. Then, it passes through the holes of the perforated plate 26 and enters the circulating air passage 27. At this time, since the perforated plate 26 serves as a baffle for suppressing the outflow of warm air, the perforated plate 26 allows the warm air to circulate uniformly inside the box 1. On the other hand, the warm air that has entered the circulation air passage 27 passes through the circulation duct 25 and blower 2
1, 22 and then again passes through the duct 23, the circulating air distribution duct 19 and the heat exchanger 14, becomes warm air, and becomes the space S.
Is blown downwards. Therefore, articles stored in the storage rack 5, such as tableware, are dried by the warm air circulating in the storage chamber in the box 1.

In such an operating state, the heat exchanger 1
The warm air circulating in the space S comes into contact with 4. Therefore, the heat efficiency of the heat exchanger 14 is higher than that in the case where the heat exchanger 14 is arranged outside the box body 1 and contacts the outside air. In addition, when the storage shelf 5 is moved by the endless chain 4, the storage shelf 5
And the uniform forced circulation action of the warm air described above are combined with each other, so that the articles stored in the respective storage shelves 5 are dried more uniformly.

In the above-mentioned embodiment, the two fans 21 and 22 blow the heat to the heat exchanger 14, and the two fans 2 also.
Since the Nos. 1 and 22 are installed in the upper and lower two stages, compared to a system in which one large blower blows air to the heat exchanger 14 or two blowers are installed side by side to blow air to the heat exchanger 14, Body 1
The blow-out width of the blowers 21 and 22 from the floor is reduced, and the floor area can be reduced accordingly.

Further, although the vertical rotating rack used for drying tableware and the like has been described in the above embodiment, the present invention can also be applied to a vertical rotating rack for storing chemicals and the like by cooling. In that case, the heat exchanger 14 is replaced with a cooler which is a kind of heat exchanger.

[0016]

As described above, according to the present invention,
Constrained play space in the guide frame of an endless chain
Since the heat exchanger is installed by using it, it is not necessary to secure an extra space outside the box for installing the heat exchanger, and it is possible to store a large amount of goods with a small floor area. You can make the most of the advantages and heat loss
Loss is small and thermal efficiency can be improved. Moreover, the above
Uniform forced circulation and collection of hot or cold air by a heat exchanger
Combined with the circulation of storage shelves, drying with warm air
Can be uniformly stored by cooling with cold air. In addition, claim 2
According to the invention of claim 1, the hot air or the cold air in the box body 1 is a perforated plate.
Which is made uniform by 26 and flows into the circulating air passage 27.
Thus, the forced circulation action of hot air or cold air can be made more uniform.
In particular, it requires a large suction force for forced circulation compared to hot air.
It is effective in cold wind.
