Description

[Detailed Description of the Invention] The present invention relates to a refrigerator management device that manages the consumption status of food and drink in a refrigerator provided in each guest room of a hotel or the like.

In recent years, in hotels, inns, etc., refrigerators are placed in each guest room, and these refrigerators are directly connected to a storage device installed at the front desk, etc., and the consumption status of food and drink in each refrigerator is stored in the storage device. When checking out a guest room, the user referred to the consumption status of the relevant refrigerator in the storage device and paid for the food and drinks taken out of the refrigerator.

By the way, in such a refrigerator management device, the structure of the refrigerator has been changed in order to prevent fraudulent activities such as drinking only the contents of a drink, for example, juice, and then putting the empty bottle back into the refrigerator. The structure is such that the food and drink taken out from the refrigerator cannot be returned to the refrigerator, or even if the food and drink can be returned, the food and drink remain in a consumed state in the storage device.

However, in the refrigerator management device having such a configuration, even if the food and drink taken out by the guest are not eaten or eaten, they are stored in the storage device as if they were eaten or eaten, and there is a risk of trouble with the guest when paying the bill.

The present invention has been made in view of the above points, and provides a refrigerator management device that eliminates troubles at the time of payment.

The present invention will be explained in detail below based on the figures.

FIG. 1 is a perspective view of a refrigerator arranged in each guest room used in the refrigerator management device of the present invention, and shows one
indicates the door, and 2, 2... indicates the columns arranged in a honeycomb shape inside the refrigerator, and each column 2, 2... indicates one refrigerated drink such as beer, youth, or cola. It's getting old.

FIG. 2 is a block diagram showing one embodiment of the refrigerator management system of the present invention, and 3 indicates food and beverages such as beer and youth stored in each column 2, 2, . . . of the refrigerator in each guest room. 4 is each column 2, 2...
It represents a food and drink detection means that is provided in the food and drink system and detects the presence or absence of food and drink 3, and is composed of, for example, a switch mechanism that changes the state depending on the presence or absence of food and drink. Reference numeral 5 denotes an optical fiber having one end provided in each column 2, 2, .
Here, the temperature measuring means 6 measures the temperature of the food and drink 3 by receiving infrared rays transmitted from the food and drink 3 via the optical fiber 5, and is constituted by an infrared sensor. In order to simplify the drawing, only one set of the food/drink detection means 4 and the optical fiber 5 are shown, but in reality, one set is provided corresponding to each column of the refrigerator in each guest room. Reference numeral 7 indicates a central processing unit connected to the food/beverage detection means 4 and the temperature measuring means 6, which controls the refrigerator, calculates charges, etc. Reference numeral 8 denotes a temperature memory connected to this central processing unit 7, which stores the temperature of food and drink inserted into each column of each refrigerator. A comparison circuit 9 compares whether the difference between the detected temperature detected by the temperature detection means 6 and the temperature in the temperature memory 8 is within a predetermined range, for example, 2°C; 10 is directly connected to the central processing unit 7; A column area (not shown) corresponding to each column 2, 2... of each refrigerator is provided, and the state of the column 2, 2... corresponding to this column area is expressed as an unconsumed state. The value is stored as 0 representing a consumption state, 1 representing a consumption state, or 2 representing an uncertain state. 11 is a printer that is connected to the central processing unit 7 and prints out receipts, etc.;
Reference numeral 12 is a keyboard for inputting information to the central processing unit 7, and is used for inputting information when starting charge calculation.

Next, the operation will be explained. Immediately before a guest checks in, each column 2, 2, . At this time, the temperature detecting means 6 sequentially detects the temperature of the food and drink stored in each column 2, 2, . do. This detected temperature is transmitted to the temperature memory 8 via the central processing unit 7, and in this temperature memory 8, the temperatures stored corresponding to the respective columns 2, 2, etc. of the refrigerator 1 are sequentially updated to the latest detected temperature. Can be rewritten. Further, each column area corresponding to the refrigerator in room 453 in the storage device 10 is all set to 0 indicating an unused state. When the guest takes out the juice from the third column, for example, the food/drink detection means 4 detects this and informs the central processing unit 7 that the juice has been taken out from the third column 2 of the refrigerator in room 453. . The central processing unit 7 is the storage device 1
For example, send the information (453, 3, 1) to 0,
1 representing the consumption state is stored in the column area corresponding to the third column 2 of the refrigerator in room 453 in the storage device 10. At the same time, temperature detection in the third column of the refrigerator in room 453 is stopped. Therefore, if the temperature of the food and drink in that column is, for example, 12°, the temperature stored in the temperature memory 8 corresponding to the third column of the refrigerator in room 453 remains at 12°C. Then, the guest realized that it was a mistake to take out the youth, and after taking it out, immediately returned it to the column 2, and the food and drink detection means 4 corresponding to the column 2 detected the youth It detects that it has been reinserted and notifies it to the central processing unit 7. The central processing unit 7 sends a temperature measurement signal to the temperature detection means 6 and reads out the temperature 12° C. stored in the temperature memory 8 corresponding to the third column of the refrigerator in room 453. On the other hand, the temperature detection means 6 detects the temperature of the youth of the column 2 detected through the optical fiber 5 and transmits it to the temperature comparison circuit 9. The temperature comparison circuit 8 compares whether the difference between the detected temperature at that time and the temperature read out to the central processing unit 7 is within a predetermined range of 2°C.
At this time, the temperature of the youth has hardly increased, so the temperature difference is within the predetermined range of 2°C, and the temperature comparison circuit 9 sends a temperature matching signal to the central processing unit 7, which receives the signal. In response, a column area corresponding to the column 2 in the storage device 10 is
Returns to 0 indicating unconsumed state.

On the other hand, if a J-Use or an empty J-Use bottle that has been left for a long time after being taken out is inserted into the column 2 with fraudulent intent, the temperature comparison circuit 9 detects the J-Use or the A comparison is made to see if the difference between the measured temperature of the empty bottle and the temperature 12°C stored in the temperature memory 8 corresponding to the third column of the refrigerator in room 453 is within a predetermined temperature of 2°C. be exposed. At this time, the youth or the empty youth bottle has been sufficiently loosened by the outside temperature, and the difference between the two temperatures is 2° C. or more, so the temperature comparison circuit 8 outputs a non-coincidence signal to the central processing unit 7. Based on this signal, the central processing unit 7
A value 2 representing an uncertain state is written in the corresponding column area in the storage device 9.

When the food and drink in the refrigerator 1 becomes insufficient due to the long stay of guests, hotel employees temporarily pay for the consumed food and drink in the refrigerator by operating the keyboard 12. After that, replenish the refrigerator with food and drinks. That is, it is possible to know whether columns 2, 2, . . . , in which the uncertain state 2 is written, exist in the refrigerator of the corresponding guest room. If there are no such columns 2, 2... in an uncertain state, the payment operation will immediately proceed, but such columns 2, 2...
..., go to the relevant cabin and check how the column is actually arranged, and then use the keyboard 12 to check the central processing unit 7.
After paying the charges and temporarily storing this payment data in the storage section of the central processing unit 7, the refrigerator 1
Replenish food and drinks.

At this time, the newly replenished food and drinks are not sufficiently cooled, and the detected temperature, for example, 18°C detected in the column where the newly replenished food and drinks are stored in the temperature memory 8 corresponding to this column 2. Since the difference between the current temperature and the temperature of 12°C is outside the predetermined range of 2°C, the corresponding column area in the storage device 10 is rewritten to 2, which represents an uncertain state, and this column area in the temperature memory 8 is rewritten by the above operation. The stored temperature corresponding to 2 is the temperature of the refilled food and drink, 18℃.
can be rewritten as However, after replenishing food and drinks, the memory device 10 can be reset by performing a reset operation from the keyboard 12.
The column area of refrigerator 1 in room 543 is rewritten to 0, which indicates an unconsumed state, and can accommodate new consumption. Furthermore, the temperature of the replenished food and drink is gradually cooled down by the cooling effect of the refrigerator, but since the food and drink detection means detects the temperature of the food and drink in each column at a 1-second cycle, the temperature memory 8 The temperatures corresponding to columns 2, 2, etc. where food and drinks have been replenished are sequentially rewritten to the latest detected temperatures, such as 17°C, 16°C, and so on. Therefore, after taking out the newly replenished food and drink from the column 2 and setting the corresponding column area of the storage device 10 to 1 representing the consumption state, the food and drink are immediately removed from the column 2 after noticing that the food has not cooled down. When inserted, the contents of the corresponding column area of the storage device 10 are returned to 0, which indicates an unconsumed state, by the same operation as described above.

As described above, the refrigerator management device of the present invention is provided with temperature detection means for detecting the temperature of food and drink in each column, and when food and drink are inserted into the column from which food and drink have been taken out, Detecting the temperature of the food and drink inserted into the column with the temperature detection means,
If this detected temperature is within the preset temperature, the contents in the storage device corresponding to the column are returned to an unconsumed state, so the food and drinks that have been taken out can be immediately inserted into the column. Therefore, when paying the bill, the food and drink was considered unconsumed, and unsuitable items such as empty bottles were inserted into the column instead of being considered consumed as was the case in the past. As a result of this, troubles regarding the consumption amount of food and drink in the refrigerator that occurred with guests when paying their bills can be resolved. Further, a temperature memory is provided for storing the temperature of food and drink stored in each column detected by the temperature detection means, and the temperature of each column of each refrigerator is sequentially detected by the temperature detection means. Since the contents of the temperature memory are sequentially rewritten to the latest detected temperature, when food and drinks are taken out, the temperature immediately before that is memorized, and the taken out food and drinks are the ones immediately after being refilled. Even if food and drink have not been sufficiently cooled, if the food and drink is immediately inserted back into the original column, the column will be considered unconsumed and the stored food and drink will be replaced. Even if there is a temperature change, it is possible to accurately determine whether the product is consumed or not.
