DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can sterilize and deodorize articles during storage, and is particularly suitable for temporarily storing cooked foods until they are used. Sterilization automatic storage to be used.

[0002]

2. Description of the Related Art Conventionally, when disinfecting or disinfecting articles such as tableware, the articles have been washed and disinfected with a disinfecting solution such as sodium hypochlorite, and then washed with water. There is a danger that the liquid will remain, and the drainage of the disinfectant will pollute the environment and cause pollution.

[0003] Another method is to disinfect and disinfect articles in the storage by filling ozone gas in a chamber of a sealable storage in which a fixed shelf is installed. This method uses a disinfectant solution. As in the case of disinfecting articles, there is no problem of toxic disinfectant remaining on the articles or pollution of drainage. In particular, this method can be suitably used when the cooked food is temporarily stored until it is used.

[0004]

However, in the above-described method of disinfecting stored articles by filling the inside of the storage room with ozone gas as described above, an operator is required to put articles in and out of the fixed shelf. Since it is necessary to work in the storage room, when the concentration of ozone gas is high, there is a risk that the health of the worker may be adversely affected, and the risk increases as the working time increases. Therefore, if the ozone gas concentration in the storage is reduced, the effect on the human body can be reduced, but there is a problem that the effects of sterilization and disinfection are reduced.

There is also a method of temporarily lowering the concentration of ozone gas while the worker enters the storage room and performs work. However, it takes time to reduce the concentration of ozone gas to a level that does not affect the human body. Since the work efficiency of loading and unloading is low and equipment for changing the ozone concentration is required,
There was a problem that the cost increased.

[0006] On the other hand, there is a method in which the inside of the storage is kept at an extremely low temperature to suppress the propagation of various bacteria without using ozone gas which is toxic to the human body in order to sterilize and disinfect the articles. Since there is a need for a cooling device, there is a problem that the cost of the equipment increases, and as described above,
It cannot be used when temporarily storing cooked ingredients until they are used.

Therefore, the present invention solves the above-mentioned problems of the prior art, and eliminates the need for an operator to enter and exit a storage room filled with ozone gas harmful to the human body, and to enter and exit the storage room.
Compartment for ozone gas leakage and invasion of external germs during storage
It is an object of the present invention to provide a sterilization automatic storage which can efficiently and at low cost sterilize and deodorize articles by minimizing only the minimum .

[0008]

For this purpose, the automatic sterilizing storage of the present invention has a storage room having an opening which can be opened and closed by a closed door, and is installed in the storage room and faces the opening. An automatic shelf having a plurality of shelf units moving along a path passing through a position, a drive control device for moving any shelf unit of the automatic shelf to an opening, and an automatic shelf filled with ozone gas in the compartment. And an ozone generator for sterilizing and deodorizing articles stored in each of the shelf units.

[0009] The sterilizing automatic storage of the present invention is characterized in that:
The height and width of the opening are the same as the height and width of the shelf unit.
Each is set to be substantially equal, and the shelf unit includes:
A plurality of shelf compartments for storing articles are provided,
Inside the door, one shelf section of the shelf unit
There is an article passage hole that allows entry and exit of articles only
Shutters move the position of the article passage hole to any shelf
Characterized in that it is provided movably to a position facing the
And

[0010]

When an article to be sterilized, disinfected, or deodorized, or an article that needs to be stored in a sterilized state for a certain period of time is to be stored in the automatic sterilization storage, the operator uses the drive control device to perform the operation. The shelf unit having the shelf section for storing articles is moved to the opening, and then the closed door is opened, and the article is placed on a predetermined shelf section of the shelf unit facing the opening, and the closed door is closed to store the article. Complete the work. The high-concentration ozone gas generated by the ozone generator is filled in the sterilizing automatic storage, and the stored articles are sterilized and deodorized by the action of the ozone gas.

In order to take out the articles stored in the storage room to the outside, the operator first moves the shelf unit where the shelf section storing the articles to be taken out through the drive control device to the opening position. And then open the closed door to take out the target article to the outside. By immediately closing the sealing door as soon as the article is taken out, leakage of ozone gas in the compartment to the outside and entry of various bacteria from the outside into the compartment can be suppressed. At this time, even if the ozone gas leaks, the concentration is rapidly reduced outside the storage room, so that it does not affect the human body.

[0012] Then, there is an article passing inside the closed door.
A shutter with a hole is provided, and the article passing hole of the shutter is moved in advance to the position opposite to the shelf section of the shelf unit of the article to be loaded and unloaded at the time of entry and exit of the article, and then the closed door is opened to enter and exit the article. Do the work. The opening area of the article passage hole of the shutter corresponds to one shelf section of the shelf unit.
It is an area that allows entry and exit of goods only after it is completed, and is smaller than the area of the entire opening, so the amount of ozone gas present in the compartment at the time of entry and exit is leaked to the outside, and various bacteria that enter the compartment from the outside Is further reduced as compared to the case where the entire opening is opened to perform the loading / unloading operation.

The opening 7 has a height and width that are equal to the height of the shelf unit 3 so that articles W can be taken in and out of the shelf unit 3 from all the shelving sections 3A of the shelf unit 3 located opposite to the opening 7. And width are set substantially equal to each other. Further, a sealing door 8 is provided in the opening 7 so as to be openable and closable, and by closing the sealing door 8, the space in the storage room 1 is sealed from the outside.

An indoor unit 9 of a cooling device for cooling the inside of the storage room is provided at a position above a corner away from the opening 7 in the storage room 1, and the indoor unit 9 is, as shown in FIG. And the outdoor unit 10 installed on the outer wall of the storage room 1.

An ozone generator 11 is provided near the blower fan 9A of the indoor unit 9 so as to generate ozone gas inside the storage room 1. Each shelf unit 3 is circulated and driven by a drive control device (not shown) so that any shelf unit 3 can be moved to a position facing the opening 7 and stopped. A controller 12 of the drive control device is installed near the opening 7 outside the storage room 1 in order to call the target shelf unit 3 of the horizontal rotating shelf 2 to the drive control device into the opening 7. Upon receiving a call command from the controller 12, the drive control device moves the shelf unit 3 in a direction in which the target shelf unit 3 reaches the opening 7 in the shortest time.

The storage room 1 configured as described above is
The opening 7 is closed by the sealing door 8 except when the articles W are taken in and out of the warehouse, and the interior of the warehouse is filled with high-concentration ozone gas generated from the ozone generator 11 and sterilized.

The articles W to be stored in the storage room 1 are transported by the worker M to the vicinity of the opening 7 by a trolley or the like, and the controller 12 is operated before the sealing door 8 is opened. The shelf unit 3 having the shelf section 3A for storing the article W is moved to a position facing the opening 7.

The controller 12 can send a command signal to the drive control device to call the shelf unit 3 at an arbitrary position on the horizontal rotating shelf 2 into the opening 7 and stop it. It can be commanded to circulate continuously.

After the target shelf unit 3 is stopped facing the opening 7, the worker M opens the sealing door 8, and the shelves facing the opening 7 from outside the opening 7. The article W is placed on the target shelf section 3A of the unit 3. Next, the closed door 8 is closed to complete the warehousing operation.

When the article W is to be unloaded from the storage room 1, the worker M operates the controller 12 before opening the closed door 8 to load the desired article W in the same manner as when entering the article. The shelf unit 3 where the existing shelf section 3A is located is moved to a position facing the opening 7.

After the shelf unit 3 is stopped, the closed door 8
Is opened, and the target article W placed on the shelf section 3A of the shelf unit 3 facing the opening 7 from outside the opening 7
Is taken out, the closed door 8 is closed, and the retrieval operation is completed.

If the controller 12 is operated and the shelf units 3 are continuously operated in the circulating operation mode after loading / unloading, the storage environment of all the articles W stored in the storage room 1 can be made uniform. Can be kept.

Further, for safety during the loading / unloading operation, an interlock mechanism is provided between the closed door 8 and the drive control device, and the closed door 8 is opened unless the shelf unit 3 is completely stopped. And the shelf unit 3 may not be moved unless the closed door 8 is closed.

Next, FIG. 3 shows the automatic sterilizing storage of this embodiment .
FIG. 3 is a partially cutaway perspective cross-sectional view showing a state where a shutter is installed , and has the same configuration inside the storage room as that shown in FIGS. 1 and 2 described above. Therefore, the present embodiment is characterized by
Inside the closed door 8 of the opening 7, a sheet in which an article passage hole 13 </ b> A that allows entry / exit of the article W to only one shelf section 3 </ b> A of the shelf unit 3 facing the opening 7 is formed. Shutter 13 is provided.

The shutter 13 has an article passing hole 13A.
The upper portion and the lower portion of the shutter 13 divided by the article passage hole 13A have a pair of wires at both ends of the shutter 13. 13B and are integrally connected.

Also, both ends of a pair of wires 13B fixed to both sides of the shutter 13 are respectively provided with openings 7
Shutter take-up unit 14 arranged at the upper and lower positions inside
Are wound together with a shutter 13 on a roll (not shown) provided in each of the
The position of the article passage hole 13A can be moved to a position facing the desired shelf section 3A of the shelf unit 3 by vertically pulling the handle 13C provided on the shelf unit 3.

The rolls of the upper and lower shutter take-up sections 14 are driven by motors, and the article passing holes 13A are automatically moved to a position facing the desired shelf section 3A according to a command from the controller 12. In this case, it is possible to prevent an operation error such as accidentally taking out an article W in a different shelf section or storing an article in a different shelf section.

In this embodiment, at the time of entry / exit of the article W, after the article passing hole 13A of the shutter 13 has been moved in advance to the position facing the shelf section 3A of the shelf unit 3 of the article W to be entered / exited, the sealing door 8 is opened. Open the doors for loading and unloading. In this case, the article passage hole 13A formed in the shutter 13
Opening area of one shelf section of the shelf unit 3
This is an area that allows entry / exit of articles only, and is much smaller than the area of the entire opening 7. Therefore, when articles W enter / exit, the amount of ozone gas present in the compartment leaks to the outside or the quantity of ozone gas from outside. The amount of germs entering the room is reduced as compared to the case where the entire opening 7 is opened and the entry and exit work is performed, and the temperature rise in the storage room due to the opening 7 is also minimized. Operating costs can be reduced. In the present embodiment, the shutter 13 is formed in a sheet shape that can be wound on the upper and lower shutter winding units 14, but there is a space above and below a wall provided with the opening 7 in the compartment. , A thin plate-shaped shutter provided with an article passage hole may be provided so as to be able to slide up and down along the opening.

Further, in this embodiment, a structure in which a horizontal rotating shelf is installed as an automatic shelf in the storage room is exemplified, but each shelf unit is arranged in a vertical direction along a closed path in a vertical plane. In this case, each shelf unit has a horizontally long shape divided into a plurality of shelf sections in a horizontal direction, and the opening is also horizontally long so as to correspond to this. I just need. In this case, when a shutter is provided at the opening, the configuration may be such that the position of the article passage hole can be moved in the horizontal direction corresponding to the shelf sections arranged in the horizontal direction.

Further, as an automatic shelf to be installed in a storage room, a structure in which a plurality of each shelf unit are connected to an end and each shelf unit can be moved to a position facing an opening of the storage room, A self-propelled type in which an independent traveling device is mounted on each shelf unit may be used.

Further, in this embodiment, the automatic sterilizing storage is configured as a refrigerator, but the refrigerator may be omitted and used as a sterilizing apparatus for sterilizing or disinfecting. In particular, cooked ingredients are used. It can be used favorably for temporary storage until it is completed.

In this case, it is preferable to provide a blower fan so that the ozone gas generated by the ozone generator can be uniformly distributed throughout the storage room. In addition, this implementation
In the example, articles are taken in and taken out from one opening, but an opening dedicated to entry and an opening dedicated to exit may be provided separately.

[0036]

As described above, according to the automatic sterilization storage of the present invention, it is not necessary for the worker to enter the storage room filled with ozone gas harmful to the human body when loading and unloading articles. Since there is no danger of harm to the health and the ozone gas concentration in the storage room can be constantly maintained at a high level, it is possible to sterilize and deodorize articles efficiently and at low cost.

[0037] Therefore, it can be suitably used especially when the cooked food is temporarily stored until it is used. In this case, the different kinds of food are used due to the deodorizing effect of ozone. Can be stored at the same time without losing the flavor.

Further, since only the articles are taken in and out from the opening, the time during which the opening is open can be shortened, and the amount of germs intruding into the storage room from the outside and the amount of ozone gas leaking from the storage room to the outside can be reduced. . Moreover, even if germs enter the storage room, they are immediately sterilized and disinfected by the high-concentration ozone gas in the storage room, and the ozone gas leaked to the outside is also diffused and diluted in the air to be immediately decomposed and rendered harmless. .

Further, by providing a shutter in which an article passage hole is formed inside the closed door at the opening ,
The opening area of the article passage hole of the shutter is the area of the entire opening
Smaller than, be suppressed from the refrigerator chamber during goods movements and the amount of ozone gas leaking to the outside, to a minimum of the amount of bacteria entering from outside into the refrigerator compartment opening facing the shelf partition only
Thus, it is possible to further reduce the number of times compared to the case where the whole opening is opened to perform the loading / unloading operation.
