no. 1 approach
[0020] based on the following Figure 1 to Figure 5 Next, refrigerator 10 according to the first embodiment of the present invention will be described in detail.
[0021] The refrigerator 10 of this embodiment can read and manage the wireless tag information stored in the wireless tag 24 attached to food.
[0022] (1) Structure of refrigerator 10
[0023] according to figure 1 ~ FIG. 3 illustrates the structure of the refrigerator 10 .
[0024] Such as figure 1 As shown, in the cabinet of the refrigerator 10, a refrigerating chamber 14, a vegetable chamber 16, an ice making chamber 18 and a freezing chamber 20 are arranged from the upper section, and a switchboard capable of switching the temperature in the refrigerator is provided on the right side of the ice making chamber 18. Room 22.
[0025] Inside the refrigerator compartment 14, an upper shelf 41, a middle shelf 39, and a lower shelf 38 are provided in the up-down direction. Lower grid 38 also doubles as the top p...
no. 2 Embodiment approach
[0055] based on the following Figure 7 The second embodiment will be described.
[0056] The difference between this embodiment and the first embodiment is that, in addition to the functions of the first embodiment, there is a configuration in which the user can write information necessary for the wireless tag 24 of food.
[0057] Such as Figure 7 As shown, the wireless tag 24 has a fixed area and a user area, and data can be written for each user in the user area. Therefore, the home server 30 designates the user to write the necessary writing information through the tag detection device 26 , whereby the user can write the necessary information in the user area of the wireless tag 24 . In this way, it is possible to differentiate among households, and it is possible to perform food management unique to the user.

Abstract
The invention provides a refrigerator to avoid manually inputting foods information, only need to put foods with wireless labels into the refrigerator to create information in refrigerator. The front antenna (52) and the back antenna (54) locate near the opening of the cold room (14), when first the front antenna (52) and then the back antenna (54) detects the information of wireless labels, it judges for storing foods, while in the opposite detective order it judges for taking out of foods.
Description
technical field [0001] The present invention relates to a refrigerator capable of storing and managing food provided with wireless tags.
