制御基板７０は、各種センサ３６、３７や操作パネル３９から入力される検出信号と予めメモリに記憶された制御プログラムに基づいて、冷蔵ダンパ２５及び冷凍ダンパ２７の開閉や、冷却器ファン２２の回転速度や、圧縮機２９の運転周波数を制御して冷蔵庫１の動作全般を制御する。 The control board 70 opens and closes the refrigerating damper 25 and the refrigerating damper 27 and rotates the cooler fan 22 based on the detection signals input from the various sensors 36 and 37 and the operation panel 39 and the control program stored in the memory in advance. The speed and the operating frequency of the compressor 29 are controlled to control the overall operation of the refrigerator 1.

このような構成の冷蔵庫１では、冷却器ファン２２の回転と、冷蔵ダンパ２５及び冷凍ダンパ２７の開閉を制御して、冷却器２１が生成した冷気を冷蔵室６及び野菜室７と、冷凍室１０へ切り替えて供給することによって、冷蔵室温度センサ３６や冷凍室温度センサ３７の検出温度が所定の温度条件を満たすように、各貯蔵室６，７，１０を冷却する。 In the refrigerator 1 having such a configuration, the rotation of the cooler fan 22 and the opening / closing of the refrigerating damper 25 and the refrigerating damper 27 are controlled, and the cold air generated by the cooler 21 is transferred to the refrigerating chamber 6 and the vegetable compartment 7 and the freezing chamber. By switching to 10 and supplying the refrigerator, the storage chambers 6, 7 and 10 are cooled so that the detected temperatures of the refrigerator compartment temperature sensor 36 and the freezer compartment temperature sensor 37 satisfy a predetermined temperature condition.

具体的には、冷蔵室６及び野菜室７を冷却する場合、圧縮機２９を駆動することで冷却器２１を低温化しつつ、冷蔵ダンパ２５を開放し冷凍ダンパ２７を閉止した状態で冷却器ファン２２を駆動する。これにより、冷却器２１で冷却された空気は、野菜室流路２４ａ、第１流路部２４ｂ、傾斜部２４ｄ及び第２流路部２４ｃを通って上方へ流れ、吹出口１８ｂ、１８ｃより冷蔵室６に供給され、冷蔵室６を冷却する。冷蔵室６を流れた空気は、仕切板１１に設けられた連通孔１７を通って野菜室７に流れ込み、野菜室７内を冷却した後、野菜室７の背面に設けられた吸込口１９ａからリターンダクト１９に取り込まれ、冷却器室２３に戻り、再び冷却器２１と熱交換して冷却される。 Specifically, when cooling the refrigerating chamber 6 and the vegetable compartment 7, the cooler fan 21 is cooled by driving the compressor 29, while the refrigerating damper 25 is opened and the refrigerating damper 27 is closed. Drive 22. As a result, the air cooled by the cooler 21 flows upward through the vegetable compartment flow path 24a, the first flow path portion 24b, the inclined portion 24d, and the second flow path portion 24c, and is refrigerated from the outlets 18b and 18c. It is supplied to the room 6 and cools the refrigerating room 6. The air flowing through the refrigerating chamber 6 flows into the vegetable chamber 7 through the communication hole 17 provided in the partition plate 11, cools the inside of the vegetable chamber 7, and then from the suction port 19a provided on the back surface of the vegetable chamber 7. It is taken into the return duct 19, returns to the cooler chamber 23, exchanges heat with the cooler 21 again, and is cooled.

また、冷凍室１０を冷却する場合、圧縮機２９を駆動することで冷却器２１を低温化しつつ、冷凍ダンパ２７を開放し冷蔵ダンパ２５を閉止した状態で冷却器ファン２２を駆動する。これにより、冷却器２１で冷却された空気は、冷凍側流路２６を通って吹出口３４より冷凍室１０に供給され、冷凍室１０を冷却する。冷凍室１０を流れた空気は、冷凍室１０の背面に設けられた吸込口１９ｂからリターンダクト１９に取り込まれ、冷却器室２３に戻り、再び冷却器２１と熱交換して冷却される。 Further, when cooling the freezer chamber 10, the cooler fan 22 is driven in a state where the refrigerating damper 27 is opened and the refrigerating damper 25 is closed while the temperature of the cooler 21 is lowered by driving the compressor 29. As a result, the air cooled by the cooler 21 is supplied to the freezing chamber 10 from the outlet 34 through the freezing side flow path 26, and cools the freezing chamber 10. The air flowing through the freezing chamber 10 is taken into the return duct 19 from the suction port 19b provided on the back surface of the freezing chamber 10, returns to the cooler chamber 23, exchanges heat with the cooler 21 again, and is cooled.

The uneven shape is not formed in the direction, and the aesthetic appearance inside the upper storage chamber 6c can be improved.

特に、後壁板４１の前面が、上方に行くほど前方へ向かうように傾斜する面からなる場合、有効活用されにくい上側貯蔵室６ｃの上奥部を、視覚的な違和感を抑えつつ後壁板４１で前後に区画し、その後方に制御基板７０等の冷蔵庫構成部品を配設するための空間を形成することができる。つまり、上側貯蔵室６ｃの実質的な収納容積や断熱性能や内部の美観を損なうことなく、冷蔵庫構成部品を配置するための空間を確保することができる。 In particular, when the front surface of the rear wall plate 41 is composed of a surface that inclines toward the front toward the upper side, the upper inner part of the upper storage chamber 6c, which is difficult to be effectively used, is covered with the rear wall plate while suppressing visual discomfort. It can be divided into front and rear by 41, and a space for arranging refrigerator components such as a control board 70 can be formed behind the partition. That is, it is possible to secure a space for arranging the refrigerator components without impairing the substantial storage volume, heat insulation performance, and internal aesthetics of the upper storage chamber 6c.

本実施形態において、後壁板４１が、後壁板４１の面外方向に段部４ｇと重なり、かつ、段部４ｇの一部を前方から覆うように内箱背面４ｅの前方に配置されている場合、後壁板４１の周縁を、左右方向及び前後方向において内箱４の段部４ｇに近接させることができる。これにより、後壁板４１が、内箱４から不自然に飛び出たように見えることなく、前延面４ａ、４ｂ、４ｃから段部４ｇを介して一続きに繋がっているように見え、上側貯蔵室６ｃ内部の美観を向上することができる。 In the present embodiment, the rear wall plate 41 is arranged in front of the inner box back surface 4e so as to overlap the step portion 4g in the out-of-plane direction of the rear wall plate 41 and to cover a part of the step portion 4g from the front. If so, the peripheral edge of the rear wall plate 41 can be brought close to the stepped portion 4g of the inner box 4 in the left-right direction and the front-back direction. As a result, the rear wall plate 41 does not appear to protrude unnaturally from the inner box 4, but appears to be continuously connected to the front extension surfaces 4a, 4b, and 4c via the step portion 4g, and is on the upper side. The aesthetic appearance inside the storage chamber 6c can be improved.

本実施形態において、後壁板４１の周縁の前側角部４１ｄが、後側角部４１ｅに比べて曲面又は平面によって大きく面取りされている場合、後壁板４１の周縁が、より一層目立ちにくくなり、上側貯蔵室６ｃ内部の美観を向上することができる。 In the present embodiment, when the front corner portion 41d of the peripheral edge of the rear wall plate 41 is chamfered by a curved surface or a flat surface as compared with the rear side corner portion 41e, the peripheral edge of the rear wall plate 41 becomes more inconspicuous. , The aesthetic appearance inside the upper storage chamber 6c can be improved.
