Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial Field of Use The present invention relates to an inventory management device for managing the inventory status of articles stored in a refrigerator or the like.

Conventional technology In household refrigerators, it is easy to forget the existence of the food stored inside the refrigerator, resulting in repurchasing food that has already been stored, or forgetting the shelf life of the food after storing it. It may cause corruption.

In order to prevent such mismanagement, for example,
Publication No. 176983 discloses a food menu that includes a clock electronic circuit section, a food information display electronic circuit section, a switch group section provided for each food item, and a display element section that displays time information and food information. Discloses a technology that allows a panel device to be connected to a power supply unit.

Problems to be Solved by the Invention In the technique disclosed in the above-mentioned publication, after the food menu board device is connected to a power source, it is used by attaching it to a refrigerator that stores and stores food. This installation may vary depending on the location.
Children, acquaintances, and other third parties who are not directly in charge of using the refrigerator are placed in a situation where they can easily access the refrigerator. There was a fear that the information could be changed.

Therefore, the present invention provides an inventory management device with a locking function to prevent stored information from being changed by careless operations.

[Structure of the Invention] Means for Solving the Problems The inventory management device of the present invention displays a plurality of types of articles, a plurality of article specification keys and a lighting device provided corresponding to each article display, and a plurality of display modes. A mode designation key that designates one of the designation keys, and a control device that stores article designation information and controls lighting of the lighting device based on the operation of both designation keys, and the control device is configured to control lighting when the mode designation key is operated. At this time, the lighting device corresponding to the operated article specification key is turned on based on the stored article specification information.

In addition, there is a display panel on which multiple types of articles and display modes are displayed, a plurality of article specification keys and lighting devices provided corresponding to each display on the display panel, an input mode, an erase mode, an inventory confirmation mode, and a lock mode. a mode designation key that designates one of a plurality of display modes consisting of a mode designation key; and a mode designation key that determines whether or not an article designation key has been operated based on the operation of the mode designation key, and lights up a lighting device that corresponds to the operated designation key. When the lock mode is designated by operating the mode designation key, if the designation of modes other than the inventory confirmation mode is canceled, the lock mode state does not become the input and deletion mode.

By operating the action mode designation key, the control device determines whether or not each item designation key has been operated, and the lighting device corresponding to the operated product designation key lights up, allowing the user to designate the desired mode. Each time the item designation key is pressed, the operating state of the article designation key is confirmed, and the control device not only functions as a storage unit for the operating state and an operation/non-operation determination unit, but also functions as a display designation unit that displays the determination result.

Additionally, if lock mode is specified using the mode specifying key, even if input mode and erase mode are subsequently specified using the mode specifying key, the operation of the article specifying key becomes invalid and the control device The information stored in the storage unit will not be changed carelessly.

Next, the display operation will be explained based on the flowchart showing the microcomputer program in Figure 6. However, starting from power-on, (1) input/confirmation mode, (i)
Each mode will be explained separately: erase mode, (i) lock mode, and (iv) timer mode.

(i) Input and confirmation mode In step S, it is determined whether the input/confirmation key 23 has been operated (pressed), and if it has not been operated, the process moves to step Mt, and if it has been operated, the process moves to step S. All the LEDs 2 G (including the LEDs corresponding to the input/confirmation key 23) corresponding to the section 14 of the food being input are turned on to display the mode status and the inputted article. Next, in step S, the article is displayed. It is determined whether or not the food has been designated by pressing (operating) the designation key (i.e., section) 14, and if it has been designated, the process moves to step S4 and it is determined whether the food has been input (i.e., designated) or not. However, if no input has been made, in step S, the timer (the microcomputer 30 is provided as part of its function as a timer) corresponding to the article designation key 14 starts an integration operation (i.e., counting the number of days). Then, proceed to step S. Therefore, when newly purchased food is stored in the refrigerator 1, the input is completed simply by pressing the input/confirm key 23 and the item designation key 14 on which the stored food is drawn, making it very easy to use. is simple and requires fewer operations. In addition, input/confirmation key 23
When you press , the section 14 corresponding to the food that has already been input is displayed.
Since all the LEDs 20 are lit, it is possible to check the food items that have been entered.

On the other hand, if no food is specified in step S, it is determined whether 10 seconds have passed after proceeding to step S, and if 10 seconds have passed, all LEDs 20 that are lit are turned off in step S. and return to step SI,
If 10 seconds have not elapsed, return to step S.

In addition, if the specified food has been input in step S4, the storage period (number of days) of the food after input is displayed on the time display section 22 in step S (the number of days is displayed instead of the normal time display). display), and the process moves to step S1°.

In step S, it is determined whether or not the mode designation key has been operated. If the mode is designated, the process returns to step SI; if the mode is not designated, step S1. It is determined whether 3 seconds have elapsed or not. If 3 seconds have not elapsed, the process returns to step S. When 3 seconds have elapsed, all lit LEDs 20 are turned off at step Sll, and the time display section 22 is turned off. Step S to erase the number of days display and display the normal time.

Return to.

(i) Erase mode If the input/confirmation key 23 is not operated in step S, it is determined in step M whether the erase key 25 is pressed (or operated), and if it is not pressed, step Move to N8, and when pressed, move to step M to select the food section (i.e. article designation key) 1 that has already been input.

(including D) to display the erase mode and input items. Next, in step M, it is determined whether the food has been designated by pressing the article designation key 14, and if it has been designated, the process moves to step M4 and it is determined whether the food has been input (i.e., designated) or not. If , has not been input, the process returns to step M, and if it has, the process moves to step M. On the other hand, if the article designation key 14 is not operated in step M, the process moves to step M6, where it is determined whether 10 seconds have elapsed, and if 10 seconds have elapsed, all the lit LEDs 20 are turned off in step M. Then, the process returns to step SI, and if 10 seconds have not elapsed, the process returns to step M.

On the other hand, in step M, the specified article specification key 1
The input corresponding to step 4 is erased, the corresponding LED 20 is turned off, the number of days counted by the timer is reset in step M, and the process moves to step S.

That is, when the stored food is taken out, the erase key 25 is pressed.
Press , then select the section corresponding to the food in question (item designation key)
When you press 14, the input is erased and erasing is completed, and it can be erased very easily with few key operations.

(j) Lock mode In step N1, it is determined whether the lock key, that is, the input/confirmation key 23 and the erase key 25 are operated at the same time. If they are not operated, the process moves to step S□; if they are operated, step N, and the lock LED corresponding to section 14L
lights up and illuminates the compartment 14L to display that it is in lock mode.Next, in step N, it is determined whether or not the input/confirmation key 23 has been operated, and if it has not been operated, the process moves to step N. When operated, all the LEDs 20 (including the LEDs corresponding to the input/confirmation key 23) corresponding to the food sections 14 that have already been input are lit to display the confirmation mode designation and inputted items in the lock mode. do. Next, in step N6, it is determined whether or not the food has been designated by operating the article designation key 14. If the food has been designated, the process moves to step N, and the storage period (days) of the designated food is set at the time. It is displayed on the display unit 22 (the number of days is displayed in place of the normal time display) and the process moves to step N. If no designation is made, the process moves to step N.

In step N, it is determined whether the lock key has been operated or not, and if it has been operated, the process moves to step N. If it has not been operated, the process moves to step N, and it is determined whether 10 seconds have elapsed. If 10 seconds have elapsed, the process moves to step N, and if 10 seconds have not elapsed, the process returns to step N. In step N, all the lit LEDs are turned off, the number of days display on the time display section 22 is switched to the normal time display, and the process returns to step SI.

Therefore, while the lock mode is specified, only the confirmation mode or unlocking can be accepted, and careless input or deletion is prevented.

(N>Timer mode Step S In 1+, it is determined whether or not the timer key 24 has been operated. If the timer key 24 has not been operated, step S is executed.

When the key is operated, the LED corresponding to the timer key 24 is made to blink in step Sat, and the hour and minute on the time display section 22 are made to blink. However, when the previous timer time is specified, the previous specified time is displayed blinking. Next, in step S, time specification key 21
It is determined whether A is operated or not, and if it is not operated, step S1. If the operation is incorrect, the specified set time is displayed at the time position in step S t4.Next, in step S □ it is determined whether or not the minute designation key 21B has been operated, and if not, step The process moves to S1M, and when operated, displays the set number of minutes specified in step Sas at the minute position, completes the timer time setting, and then proceeds to step S8. Move to.

On the other hand, step S1? and Sas, it is determined whether 5 seconds have elapsed or not, and if 5 seconds have not elapsed, step S2. and return to So, and after 5 seconds, step StS and S, respectively. Move to.

Step S. Then, it is determined again whether or not the timer key 24 has been operated. If the timer key 24 has not been operated, the process moves to steps S and 4; if it has been operated, the process moves to steps S and l to subtract the specified timer time ( That is, the timer operation) is started, and the blinking timer LED is turned on to indicate that the timer mode and timer counting are in progress. In addition, step S. If neither the hour designation key 21A nor the minute designation key 21B is operated at the time of transition to , the previous designated time or 0:00 will be displayed.

Next step S. It is determined whether the timer time count has ended or not, and if it has not ended, step S is executed. Repeat and when finished, go to step S.

The timer LED that was lit at step S is turned off, and the notification buzzer is activated for only 10 seconds to notify the end of the timer time, and the process returns to step S.

On the other hand, in step S, 4, it is determined whether 10 seconds have elapsed, and if 10 seconds have not elapsed, step S.

Return to Step S after 10 seconds. Move to.

During the timer count, the remaining time can be made clear by subtracting and displaying the timer time by a predetermined time every time a predetermined time (for example, one minute) elapses from the specified timer time. Further, when the timer key 24 is operated during timer counting, it is preferable that the timer mode ends and the process returns to step S1.

In the above embodiments, an example has been shown in which the present invention is applied to food inventory in the refrigerator 10, but the present invention is not limited to this, and may be applied to the management of article inventory in a storage area such as a commercial freezer.
