A control system for providing such meal plan information will be explained in more detail.

FIG. 16 is a block diagram schematically illustrating a control system in the refrigerator. A controller 120 for controlling an operation of the refrigerator is connected to the display 110 and a touch panel 110a of the display 110, thereby storing personal information input by a user in a personal information storage device 122. The controller 120 is connected to a food material information storage device 124 for storing information on types and the amount of food items stored in the refrigerator. The food material information storage device 124 may store information read by a barcode reader or an image recognition device, or information received from outside. Alternatively, information directly input by a user may be stored in the food material information storage device 124.

The refrigerator also includes a recipe storage device 126 for storing various recipes and calories per recipe, and a food information storage device 128 for storing information on each food material or effects of each dish. Information may be input to the recipe storage device 126 and the food information storage device 128 in advance. Such information may be periodically updated by a communication means 130 of the refrigerator.

The personal information may include health-related various information measured by a medical institution or an examination institution, as well as the aforementioned age, height, weight, blood pressure, medical history and allergic food. Such information may include a prescription and a medical checkup record. Such information should be continuously updated for provision of a correct meal plan, because the personal information such as the height, the weight and the blood pressure changes according to lapse of time. In a case where a user takes a medical examination or a checkup at the medical institution or the examination institution, the user's height, weight, blood pressure, etc. may be measured. Such information may be utilized to update the personal information stored in the refrigerator.

For this, the communication means 130 is configured to be connected to an external personal information server 10 provided at a medical institution or an examination institution, through a wideband network such as the Internet, and to receive newly-measured information.

Such personal information may be measured at any place rather than the aforementioned institutions. For instance, such personal information may be frequently measured by a user's extensometer or body weight scale. Alternatively, such personal information may be measured by various types of external measuring devices 20 equipped in a fitness club, etc. In recent years, the external measuring device 20 is provided with a communication means. Accordingly, such personal information may be updated using the external measuring device 20.

Alternatively, such personal information may be updated as a user touches the touch panel.

FIG. 17 is a block diagram schematically illustrating a method for connecting the external personal information server 10 with the communication means 130 of the refrigerator. The communication means may be connected to the external personal information server 10 provided at an external institution (e.g., medical institution or examination institution), via a central server 30. The central server 30 is configured to store information acquired from a plurality of institutions in an assembled manner. Under such configuration, a user can easily receive personal information measured at various places if he or she is connected to the single central server 30.

The communication means 130 may be connected to a mobile terminal 40 such as a smart hone. The mobile terminal 40 may be connected to the external personal information server 10 through a mobile communication network such as an Internet network, a 3G or an LTE network. Personal information stored in the mobile terminal 40 may be connected to the communication means 130 through a wired or wireless network provided at a user's home or an NFC. In this case, a user's authentication process through the mobile terminal 40 is facilitated. Accordingly, authentication procedures can be simplified, and information leakage due to hacking, etc. can be reduced. Alternatively, the communication means 130 and the external personal information server 10 may be directly connected to each other.

FIG. 18 is a block diagram schematically illustrating a method for connecting the external measuring device 20 to the communication means 130. The external measuring device 20 may be connected to the communication means 130 through an NFC tag 42 of the mobile terminal 40. For this, the external measuring device 20 includes the NFC tag 22, a measuring means 24, and a microcomputer 26 for controlling an operation of the NFC tag 22 and the measuring means 24. Once personal information is measured by the measuring means 24, the personal information is transmitted to the mobile terminal 40 through the NFC tag 22. Then, the personal information transmitted to the mobile terminal 40 may be transmitted to the communication means 130 through a wired or wireless network provided at home.

The mobile terminal 40 and the communication means 130 of the refrigerator may be connected to each other through an NFC. The external measuring device 20 and the mobile terminal 40 may be connected to each other through a wired or wireless communication means.

Such personal information transmitted to the refrigerator is compared with pre-stored personal information for update. More specifically, personal information is stored in the personal information storage device 122 together with a measured time. Accordingly, upon input of new personal information, a measured time of the new personal information is compared with that of the pre-stored personal information for determination whether to update the pre-stored personal information or not. Generally, a user directly inputs his or her personal information to the touch panel, shortly after measurement of the personal information. Accordingly, an update process is performed by considering an input value as recent information. In a case where information is received from an external institution or an external measuring device, a measured time of the information is compared with that of pre-stored information. As a result of the comparison, whether to update the pre-stored information or not may be determined.

Under such configuration, a user's personal information can be continuously updated, and thus a more precise meal plan can be provided.

Processes of providing a meal plan based on various types of input information will be explained.

A reference meal plan may be firstly set. Then a meal plan may be generated by excluding dishes cooked with ingredients which should not be taken, from the reference meal plan. That is, dishes which can be cooked by utilizing all food ingredients stored in the refrigerator are provided. Then, the dishes are combined with one another to determine a reference meal plan. Then, dishes using harmful ingredients may be excluded from the reference meal plan by considering a user's designated item, thereby determining a meal plan. For instance, if a user's designated item is hypertension, dishes using ingredients harmful to hypertension may be excluded from the entire dishes included in the reference meal plan. Then, the rest dishes may be used to determine a meal plan.

In case of a family meal plan, dishes harmful to members may be excluded from the entire dishes included in the reference meal plan. Then, the rest dishes may be used to determine a meal plan.

Alternatively, ingredients (food materials) harmful to a user's designated item may be excluded from all stored ingredients. Then, the rest ingredients may be used to determine a meal plan.

The foregoing embodiments and advantages are merely exemplary and are not to be considered as limiting the present disclosure. The present teachings can be readily applied to other types of devices. This description is intended to be illustrative, and not to limit the scope of the claims. Many alternatives, modifications, and variations will be apparent to those skilled in the art.
