Is possible.

図５は、本実施の形態における冷蔵庫の一動作例を示す第１のフローチャートである。まず、処理を開始し、制御基板７は、野菜栽培モード設定がＯＮであるか否かを判定する（Ｓ１１）。野菜栽培モード設定がＯＮでない場合（Ｓ１１：Ｎｏ）、すなわち野菜栽培モード設定がＯＦＦである場合には、野菜栽培モード設定がＯＮになるまで判定を繰り返す。野菜栽培モード設定がＯＮである場合（Ｓ１１：Ｙｅｓ）には、制御基板７は、野菜栽培室ヒータ１１ａ，１１ｂ，１１ｃ，１１ｄをＯＮし、野菜栽培室４ｂ内の温度を１０℃に上昇させる（Ｓ１２）。なお、必要に応じて野菜貯蔵室温度補償ヒータ１０ａ，１０ｂも用いる。野菜貯蔵室温度補償ヒータ１０ａ，１０ｂを用いる場合には野菜貯蔵室４ａと野菜栽培室４ｂの温度差が小さくなり、消費電力を抑えることができる。なお、野菜栽培室ヒータ１１ａ，１１ｂ，１１ｃ，１１ｄをＯＮする際にはいずれか１つのみをＯＮしてもよい。  FIG. 5 is a first flowchart showing an operation example of the refrigerator in the present embodiment. First, the process is started, and the control board 7 determines whether or not the vegetable cultivation mode setting is ON (S11). When the vegetable cultivation mode setting is not ON (S11: No), that is, when the vegetable cultivation mode setting is OFF, the determination is repeated until the vegetable cultivation mode setting is turned ON. When the vegetable cultivation mode setting is ON (S11: Yes), the control board 7 turns on the vegetable cultivation room heaters 11a, 11b, 11c, and 11d, and raises the temperature in the vegetable cultivation room 4b to 10 ° C. (S12). In addition, vegetable storage room temperature compensation heaters 10a and 10b are also used as necessary. When the vegetable storage room temperature compensation heaters 10a and 10b are used, the temperature difference between the vegetable storage room 4a and the vegetable cultivation room 4b is reduced, and power consumption can be suppressed. Note that only one of the vegetable cultivation room heaters 11a, 11b, 11c, and 11d may be turned on.

次に、制御基板７は、給水タンク１３の水位がしきい値、ここでは１０％未満であるか否かを判定する（Ｓ１３）。給水タンク１３の水位は、内部に設置した浮きにより検知し、浮きに取り付けられた磁石により磁気センサを反応させることで実現することができる。給水タンク１３の水位が１０％未満である場合（Ｓ１３：Ｙｅｓ）には、ユーザに対して給水タンク１３に給水すべきことを報知する。ここでは、アラーム鳴動し、給水ランプを点滅させる（Ｓ１４）ことで給水タンク１３に給水すべきことを報知してＳ１３に戻る。給水タンク１３の水位が１０％未満でない場合（Ｓ１３：Ｎｏ）、すなわち給水タンク１３の水位が１０％以上である場合には、操作パネル３に、栽培できる野菜のリストを表示する（Ｓ１５）。その後、端子Ａに推移する。  Next, the control board 7 determines whether or not the water level of the water supply tank 13 is less than a threshold value, here 10% (S13). The water level in the water supply tank 13 can be detected by detecting the float installed inside and reacting the magnetic sensor with a magnet attached to the float. When the water level of the water supply tank 13 is less than 10% (S13: Yes), the user is notified that the water supply tank 13 should be supplied with water. Here, an alarm is sounded and the water supply lamp blinks (S14) to notify that the water supply tank 13 should be supplied with water, and the process returns to S13. When the water level of the water supply tank 13 is not less than 10% (S13: No), that is, when the water level of the water supply tank 13 is 10% or more, a list of cultivatable vegetables is displayed on the operation panel 3 (S15). Thereafter, the terminal A changes.

図６は、本実施の形態における冷蔵庫の一動作例を示す第２のフローチャートである。まず、図５の端子Ａから推移して、栽培する野菜がユーザによってリストから選択される（Ｓ２１）。そして、選択された野菜が種から栽培されるものであるか否かを判定する（Ｓ２２）。  FIG. 6 is a second flowchart illustrating an operation example of the refrigerator in the present embodiment. First, it changes from the terminal A of FIG. 5, and the vegetable to grow is selected from a list by the user (S21). Then, it is determined whether or not the selected vegetable is cultivated from the seed (S22).

種から栽培されるものである場合（Ｓ２２：Ｙｅｓ）には、種から栽培する環境に合わせた制御を行う（Ｓ２３）。種から栽培する環境に合わせた制御は、具体的には、発芽を促進させるために野菜栽培室４ｂの野菜栽培室ヒータ１１ａ，１１ｂ，１１ｃ，１１ｄをＯＮし、野菜栽培室４ｂ内を一例として２０℃で６時間保持する。また、このときにＬＥＤ群６を点灯を制御して昼夜を模擬することで発芽の促進が可能である。その後、発芽したか否かの判定を行う（Ｓ２４）。発芽していない場合（Ｓ２４：Ｎｏ）には、種から栽培する環境に合わせた制御を継続する。発芽した場合（Ｓ２４：Ｙｅｓ）には、発芽した種の環境に合わせた制御を行う（Ｓ２５）。発芽したか否かの判定は、カメラ５により取得した画像により判定すればよい。その後、栽培を開始してから一週間経過したか否かの判定を行う（Ｓ２６）。栽培を開始してから一週間経過していない場合（Ｓ２６：Ｎｏ）には発芽した種の環境に合わせた制御（Ｓ２５）を継続する。  When it is cultivated from seeds (S22: Yes), control according to the environment cultivated from seeds is performed (S23). Specifically, the control according to the environment cultivated from seeds is performed by turning on the vegetable cultivation room heaters 11a, 11b, 11c, and 11d of the vegetable cultivation room 4b to promote germination, and taking the inside of the vegetable cultivation room 4b as an example. Hold at 20 ° C. for 6 hours. At this time, germination can be promoted by controlling lighting of the LED group 6 to simulate day and night. Thereafter, it is determined whether or not germination has occurred (S24). When it has not germinated (S24: No), control according to the environment cultivated from the seed is continued. When germinating (S24: Yes), control according to the environment of the germinated seed is performed (S25). Whether or not germination has occurred may be determined from an image acquired by the camera 5. Thereafter, it is determined whether or not one week has passed since the cultivation was started (S26). When one week has not passed since the cultivation was started (S26: No), the control (S25) according to the environment of the germinated seed is continued.

種から栽培されるものでない場合（Ｓ２２：Ｎｏ）には、選択された野菜が苗から栽培されるものであるか否かを判定する（Ｓ２７）。苗から栽培されるものでない場合（Ｓ２７：Ｎｏ）には、Ｓ２２に戻り、種から栽培されるものであるか否かの判定を行う。苗から栽培されるものである場合（Ｓ２７：Ｙｅｓ）又は種から栽培されて一週間経過している場合（Ｓ２６：Ｙｅｓ）には、Ｓ２１で選択した野菜の育成に合わせた制御を行う（Ｓ２８）。また、野菜が苗まで成長すると積極的に光合成を行うため、ＬＥＤ群６を点灯させることで、栽培される野菜の成長を促進し、栄養価を向上させることができる。  When not cultivated from seeds (S22: No), it is judged whether the selected vegetables are cultivated from seedlings (S27). When it is not what is cultivated from a seedling (S27: No), it returns to S22 and it is determined whether it is what is cultivated from a seed. When it is cultivated from seedlings (S27: Yes) or when it has been cultivated from seeds and one week has passed (S26: Yes), control according to the growth of the vegetables selected in S21 is performed (S28). ). Moreover, since a photosynthesis is actively performed when a vegetable grows to a seedling, by making the LED group 6 light, the growth of the cultivated vegetable can be promoted and a nutritional value can be improved.

なお、栽培する野菜として小松菜を選択した場合には、小松菜は発芽してから比較的早く成長するので、野菜栽培室ヒータ１１ａ，１１ｂ，１１ｃ，１１ｄを通電させて野菜栽培室４ｂ内を制御して２０℃の状態を６時間維持し、野菜栽培室４ｂ内を２０℃とする６時間と、前後３時間の計１２時間、ＬＥＤ群６を点灯させることで、栄養価の向上が可能である。なお、残りの１２時間は、ＬＥＤは消灯させる。このような周期を一週間繰り返す。その後、端子Ｂに推移する。  When Komatsuna is selected as the vegetable to be cultivated, the Komatsuna grows relatively quickly after germination. Therefore, the vegetable cultivation room heaters 11a, 11b, 11c, and 11d are energized to control the inside of the vegetable cultivation room 4b. The state of 20 ° C is maintained for 6 hours, and the LED group 6 is turned on for a total of 12 hours, 6 hours for setting the inside of the vegetable cultivation room 4b to 20 ° C and 3 hours before and after, thereby improving the nutritional value. . The LED is turned off for the remaining 12 hours. Such a cycle is repeated for one week. After that, the terminal B changes.

図７は、本実施の形態における冷蔵庫の一動作例を示す第３のフローチャートである。まず、図６の端子Ｂから推移して、栽培している野菜が食べ頃であるか否かの判定を行う（Ｓ３１）。ここで、野菜が食べ頃であるか否かの判定は、カメラ５により取得した画像データを用いて制御基板７が行う。栽培している野菜が食べ頃でない場合（Ｓ３１：Ｎｏ）には、食べ頃であるか否かの判定を繰り返す。  FIG. 7 is a third flowchart showing one operation example of the refrigerator in the present embodiment. First, it changes from the terminal B of FIG. 6, and it is determined whether or not the cultivated vegetables are ready to eat (S31). Here, the control board 7 uses the image data acquired by the camera 5 to determine whether or not the vegetables are ready to eat. If the cultivated vegetables are not ready to eat (S31: No), the determination of whether or not they are ready to eat is repeated.

ここで、栽培している野菜が食べ頃であるか否かを判定する方法について説明する。判定方法の一例には、栽培する野菜の生育期間を予め冷蔵庫操作パネルを通して設定しておく方法を例示することができる。野菜栽培室において栽培される野菜は個体差による成長速度の差はあるものの、温度、湿度及び光の供給量が一定であるため、自然環境よりも個体差が小さい。そこで、一例として栽培している野菜がトマトであれば栽培開始から２か月後を食べ頃と設定し、小松菜であれば栽培開始から１か月後を食べ頃と設定する。  Here, a method for determining whether or not the cultivated vegetables are ready to eat will be described. As an example of the determination method, a method of previously setting the growing period of the cultivated vegetable through the refrigerator operation panel can be exemplified. Although the vegetables grown in the vegetable cultivation room have different growth rates due to individual differences, the individual differences are smaller than the natural environment because the temperature, humidity, and light supply amount are constant. Therefore, as an example, if the cultivated vegetable is a tomato, 2 months after the start of cultivation is set as eating time, and if it is Komatsuna, 1 month after the cultivation start is set as eating time.

判定方法の他の一例には、栽培する野菜の画像を前日の画像と比較する方法を例示することができる。すなわち、カメラ５により取得した画像を１日１回の頻度で１日前の画像と比較し、１日前に取得した画像と本日取得した画像とを比較して差がなく、成長が止まった時を食べ頃であるとする。又は、葉物野菜の場合には栽培している野菜の大きさが、野菜栽培室４ｂ内の空間に対して８割以上の大きさまで成長した時を食べ頃であるとする。熟すると色が変化する野菜については、色の変化後に１日１回の頻度で１日前の画像と比較し、色の変化がなくなった時を食べ頃であるとする。  As another example of the determination method, a method of comparing an image of a vegetable to be cultivated with an image of the previous day can be exemplified. That is, when the image acquired by the camera 5 is compared with the image of the previous day at a frequency of once a day, the image acquired one day ago is compared with the image acquired today, and when the growth stops Suppose you are eating. Alternatively, in the case of leafy vegetables, it is assumed that the time when the size of the cultivated vegetable has grown to a size of 80% or more of the space in the vegetable cultivation room 4b is about to eat. As for vegetables whose color changes when ripening, it is assumed that it is about to eat when there is no color change compared to the image one day before at a frequency of once a day after the color change.

栽培している野菜が食べ頃である場合（Ｓ３１：Ｙｅｓ）には、冷蔵庫１の周辺が明るいか否かの判定を行う（Ｓ３２）。ここで、冷蔵庫１の周辺が明るいか否かの判定は、照度センサ８により取得した冷蔵庫１の周辺の明るさのデータを用いて制御基板７が行う。ここで、冷蔵庫１の周辺は、一例として冷蔵庫１が設置された部屋全体である。なお、冷蔵庫１の周辺の明るさの検知は、人の存在の有無を知るための手段に過ぎないため、照度センサ８に代えて人感センサが用いられてもよい。なお、栽培している野菜が食べ頃である場合には、野菜栽培室４ｂ内の温度を下げて野菜の劣化を抑制するように制御することが好ましい。冷蔵庫１の周辺が明るくない場合（Ｓ３２：Ｎｏ）、すなわち暗い場合には、明るくなるまで判定を繰り返す。冷蔵庫１の周辺が明るい場合（Ｓ３２：Ｙｅｓ）には、ユーザに対して栽培中の野菜が食べ頃であることを報知する。ここでは、アラーム鳴動し、操作パネル３に栽培中の野菜が食べ頃である旨を表示する（Ｓ３３）。ただし、アラームが常時鳴動していると不快であるため、冷蔵庫１の周辺に人が存在している場合には、一例として１時間に１度鳴動するよう設定する。又は、ネットワークを介してユーザに報知する構成であってもよい。  When the cultivated vegetables are about to eat (S31: Yes), it is determined whether or not the periphery of the refrigerator 1 is bright (S32).

In addition, when the cultivated vegetable is in the time of eating, it is preferable to control so that the temperature in the vegetable cultivation room 4b may be lowered and deterioration of the vegetable may be suppressed. When the periphery of the refrigerator 1 is not bright (S32: No), that is, when it is dark, the determination is repeated until it becomes bright. When the periphery of the refrigerator 1 is bright (S32: Yes), the user is notified that the vegetables being grown are about to be eaten. Here, an alarm sounds and a message is displayed on the operation panel 3 that the vegetable being grown is about to be eaten (S33). However, since it is uncomfortable if the alarm is always sounding, when a person is present around the refrigerator 1, as an example, the alarm is set to sound once an hour. Or the structure which alert | reports to a user via a network may be sufficient.

次に、操作パネル３に対して操作があるか否かの判定を行う（Ｓ３４）。操作パネル３に対して操作がない場合（Ｓ３４：Ｎｏ）には、操作がなされるまで判定を繰り返す。操作パネル３に対して操作がある場合（Ｓ３４：Ｙｅｓ）には、アラーム鳴動を停止する（Ｓ３５）。次に、野菜栽培室４ｂに野菜がないか否かの判定を行う（Ｓ３６）。野菜栽培室４ｂに野菜がある場合（Ｓ３６：Ｎｏ）には、野菜がなくなるまで判定を繰り返す。野菜栽培室４ｂに野菜がない場合（Ｓ３６：Ｙｅｓ）には、処理を終了する。  Next, it is determined whether or not there is an operation on the operation panel 3 (S34). If there is no operation on the operation panel 3 (S34: No), the determination is repeated until the operation is performed. When there is an operation on the operation panel 3 (S34: Yes), the alarm sound is stopped (S35). Next, it is determined whether there is no vegetable in the vegetable cultivation room 4b (S36). When there is a vegetable in the vegetable cultivation room 4b (S36: No), the determination is repeated until the vegetable runs out. A process is complete | finished when there is no vegetable in the vegetable cultivation room 4b (S36: Yes).
