- the expiration date set values from the expiration date management database 602 are shown in the upper right table of FIG. 7B.
- the shelf life of "Round plate" is 36 hours added to the current time, as shown in Fig. 7B. 00 ”. From this point on, the expiry date can be recalculated from the history information of the temperature information, as in (1) above.
- a more effective expiration date estimation result can be obtained.
- the time required for the cooking process can be used. It is thought that those that cooked for a long time have longer shelf-life than those that cooked quickly in less time.
- the cooking time includes the time information input from timer 309, food such as cooking table 104, gas cooker 103, microwave oven 107, etc., and cooking utensils such as containers and kitchen knives.
- the article management means 303 can judge and register it in the article database 304.
- the registered cooking time and the standard cooking time registered in the expiration date database 602 are awarded.
- a more effective expiration date can be calculated and estimated by the expiration date management means 601.
- a more effective expiration date estimation result can be obtained based on the tendency of each household. For example, it is possible to use the past food disposal and eating and drinking times of each household. Types of food that were disposed of earlier in the past should be set earlier than the normal expiration date, and types of food that have been eaten or consumed even after the normal expiration date will be later than the normal expiration date. Set to the time. As an example, the time information input from the timer 309 and the detection information such as the cleaning of the container with the wireless IC tag reader 120d, 120e, 120g such as the sink 105 or the dishwasher 10 or the trash can 108 and the disposal of food Is registered in the article database 304 by the article management means 303.
- This registered information is obtained by the expiration date management means 601 and it is possible to determine that it has been discarded earlier than usual and set the expiration date earlier than the normal expiration date. Become. [0189] Also, when cooking with low salt content based on the tendency of each household, the expiration date is generally earlier than usual, so it should be set earlier than the normal expiration date. You can also. As an example, the cooked food is registered in the article database 304 by the article management means 303 such that the amount of seasonings used is less than usual or is not used. Expiration date management means 601 obtains this registered information, makes a judgment that it has been discarded earlier than usual, and can set the expiration date earlier than the normal expiration date. Become.
- the expiration date management means 601 when the expiration date is estimated by the expiration date management means 601, various information can be provided to the user using the input / output device 306.
- the shelf life of the target food can be normally presented, but other useful information is also displayed by the shelf life management means 601. Supplementally, by outputting via the input / output device 306, it is possible to realize effective information provision that is more easily understood by the user.
- the history information (when cooking power, when opened, etc.) is added to the expiration date, and the user calculated the expiration date.
- the provision of information that can be fully understood can be realized by the expiration date management means 601 and the input / output device 306.
- the expiration date management means 601 and the input / output device 306 can also warn that the expiration date close to the response to the user's inquiry is approaching. For example, when the time until the expiration date reaches a preset time, it can be displayed on the display 306b with a warning sound or by sending a warning email to the user's mobile phone. As shown in FIGS. 14C and 14D, the expiration date management means 601 and the input / output device 306 are used to indicate the cause of the shortening of the expiration date (standby state, room temperature rise, etc.) The user can be alerted.
- the expiration date management means 601 and the input / output device 306 can give the user an advice for extending the expiration date just by giving a warning.
