In such a refrigerator, dampers are used to separately control the flow of cool air in the switchable compartment and the refrigerating compartment, taking into account the temperature balance between the switchable compartment and the refrigerating compartment (for example, patent Reference 1).

特開２００３－１９４４４９号公報Japanese Patent Application Laid-Open No. 2003-194449

さて、近年では、例えばソフト冷凍温度帯、パーシャル温度帯およびチルド温度帯といった複数の温度帯に切り替え可能な切替室が望まれている。
しかしながら、切替室を複数の温度帯に切り替え可能とするためには、切替室への冷気の供給と切替室からの冷気の吸い出しとを制御する必要があり、また、冷蔵室が過度に冷却されないようにするために切替室と冷蔵室との間の冷気の流れも調整する必要がある。 In recent years, there has been a demand for a switchable chamber capable of switching between a plurality of temperature zones such as a soft freezing temperature zone, a partial temperature zone and a chilled temperature zone.
However, in order to enable the switchable compartment to be switched between a plurality of temperature zones, it is necessary to control the supply of cool air to the switchable compartment and the suction of cool air from the switchable compartment, and to prevent the refrigerator compartment from being excessively cooled. It is also necessary to regulate the flow of cool air between the switching compartment and the refrigerating compartment in order to achieve this.

その結果、冷蔵室と切替室との間の冷気の流れを調整するためのダンパと、切替室の冷気の供給と吸い出しとを調整するためのダブルダンパとが必要となり、温度を制御するための機構が大型化して貯蔵室の大容量化を阻害する要因となっていた。
そこで、温度を制御するための機構を大型化することなく、複数の温度帯に切り替え可能な切替室の温度を精度良く制御することができる冷蔵庫を提供する。 As a result, a damper for regulating the flow of cool air between the refrigerating compartment and the switching compartment and a double damper for regulating the supply and suction of the cool air in the switching compartment are required, and a damper for controlling the temperature is required. The large size of the mechanism has been a factor that hinders the increase in the capacity of the storage room.
Therefore, the present invention provides a refrigerator capable of accurately controlling the temperature of a switchable compartment capable of switching between a plurality of temperature zones without increasing the size of the mechanism for controlling the temperature.

実施形態の冷蔵庫は、冷気を生成する冷却器と、冷却器で生成した冷気が流通する冷気通路と、設定温度を切り替え可能に設けられている貯蔵室であって、冷気通路から内部に冷気が供給される供給口と、内部から冷却器側に冷気が吸い出される吸出口とが形成されている切替室と、供給口から供給される冷気の流路を開閉する供給側開閉板、および吸出口から吸い出される冷気の流路を開閉する吸出側開閉板を有し、１つのモータにより供給側開閉板および吸出側開閉板の双方の開閉状態を切り替えるモータダンパと、を備える。 A refrigerator according to an embodiment includes a cooler that generates cold air, a cold air passage through which the cold air generated by the cooler is circulated, and a storage room that is provided so as to be able to switch between set temperatures, and the cold air is introduced into the interior from the cold air passage. A switching chamber having a supply port for supplying cold air, a suction port for sucking cold air from the inside to the cooler side, a supply side opening/closing plate for opening and closing the flow path of the cold air supplied from the supply port, and a suction port. a motor damper that has a suction side opening/closing plate that opens and closes a flow path of cool air sucked from an outlet, and that switches between open/closed states of both the supply side opening/closing plate and the suction side opening/closing plate by a single motor.

以下、実施形態について図面を参照しながら説明する。
図１に示すように、冷蔵庫１は、正面側に前面開口を有する矩形箱状の本体２内に、冷蔵温度帯の冷蔵室３および野菜室４、冷凍温度帯の製氷室、小冷凍室５および大冷凍室６等の複数の貯蔵室を備えている。なお、製氷室は、小冷凍室５と左右に隣り合うように配置されているため、その扉とともに図示を省略する。冷蔵室３は、いわゆる回動式の扉３ａによって開閉される。ただし、扉３ａは、観音開き式のものであってもよい。野菜室４、小冷凍室５および大冷凍室６は、それぞれ引き出し式の扉４ａ、扉５ａおよび扉６ａによって開閉される。なお、冷蔵庫１の構成は一例であり、貯蔵室の数や配置はこれに限定されない。 Hereinafter, embodiments will be described with reference to the drawings.
As shown in FIG. 1, a refrigerator 1 has a rectangular box-shaped main body 2 with a front opening, which contains a refrigerating temperature zone 3 and a vegetable compartment 4, a freezing temperature zone ice making compartment, and a small freezer compartment 5. and a plurality of storage compartments such as a large freezer compartment 6 . Since the ice making compartment is arranged so as to be adjacent to the small freezer compartment 5 on the left and right, the illustration of the ice making compartment and its door is omitted. The refrigerator compartment 3 is opened and closed by a so-called rotating door 3a. However, the door 3a may be of a double-door type. The vegetable compartment 4, the small freezer compartment 5, and the large freezer compartment 6 are opened and closed by drawer-type doors 4a, 5a, and 6a, respectively. In addition, the structure of the refrigerator 1 is an example, and the number and arrangement|positioning of a storage chamber are not limited to this.

また、冷蔵室３の下部には、冷蔵温度帯の貯蔵室であって、冷蔵室３とは異なる温度帯に制御される切替室７が設けられている。この切替室７は、本実施形態では、ソフト冷凍温度帯、パーシャル温度帯およびチルド温度帯の３段階に切り替え可能に構成されている。また、切替室７の後部側には、内部に冷気が供給される供給口７ａと、内部から冷気が吸い出される吸出口７ｂとが形成されている。 In the lower part of the refrigerating chamber 3, a switching chamber 7, which is a storage chamber for a refrigerating temperature range and is controlled to a temperature range different from that of the refrigerating chamber 3, is provided. In this embodiment, the switchable chamber 7 is configured to be switchable between three stages of a soft freezing temperature range, a partial temperature range, and a chilled temperature range. In addition, a supply port 7a for supplying cold air to the interior thereof and a suction port 7b for sucking the cold air from the interior thereof are formed on the rear side of the switching chamber 7 .

この冷蔵庫１には、冷蔵室３よりも下方となる野菜室４の後方に位置して、冷蔵温度帯の冷気を生成する冷蔵用冷却器８（図２参照）と２つのファン９ａ、ファン９ｂ（図２参照）とを有する冷却器ユニット１０が設けられている。また、この冷却器ユニット１０の上方であって概ね切替室７の後方に位置して、モータダンパ１１が設けられている。なお、モータダンパ１１の詳細については後述する。 This refrigerator 1 includes a refrigerating cooler 8 (see FIG. 2) that is positioned behind a vegetable compartment 4 below a refrigerating compartment 3 and generates cool air in a refrigerating temperature range, and two fans 9a and 9b. (see FIG. 2) is provided. A motor damper 11 is provided above the cooler unit 10 and generally behind the switching chamber 7 . Details of the motor damper 11 will be described later.

また、冷蔵庫１には、冷凍室の後方に位置して、冷凍温度帯の冷気を生成する冷凍用冷却器１２と、冷凍用冷却器１２で生成された冷気を送風するファン１３が設けられている。つまり、冷蔵庫１は、複数の冷却器を備えているとともに、本実施形態では冷蔵用冷却器８に対して複数ここでは２つのファン９ａおよびファン９ｂを備えている。 In addition, the refrigerator 1 is provided with a freezing cooler 12 that is positioned behind the freezer compartment to generate cold air in a freezing temperature range, and a fan 13 that blows the cold air generated by the freezing cooler 12 . there is In other words, the refrigerator 1 has a plurality of coolers, and in this embodiment, it has a plurality of fans 9a and 9b, two fans 9a and 9b for the cooler 8 for refrigeration.

これら冷蔵用冷却器８および冷凍用冷却器１２は、本体２の底部に設けられている機械室１４に配置されたコンプレッサ１５等とともに、周知の冷凍サイクルを構成している。そして、冷蔵庫１は、貯蔵室に設けられている図示しない温度センサや湿度センサの測定値に冷凍サイクルを運転することにより、各貯蔵室を所定の温度範囲に制御する。 These refrigerating cooler 8 and freezing cooler 12 constitute a well-known refrigerating cycle together with a compressor 15 and the like arranged in a machine room 14 provided at the bottom of the main body 2 . The refrigerator 1 controls each storage compartment to a predetermined temperature range by operating the refrigerating cycle according to the measured values of temperature sensors and humidity sensors (not shown) provided in the storage compartments.

このとき、冷蔵用冷却器８で生成された冷気は、矢印Ａで示すように、冷蔵室３の後壁を形成するダクトカバー１６の背面側に形成されている背面ダクト１７を通り、冷蔵室３および野菜室４に供給された後、冷却器ユニット１０に戻される。この背面ダクト１７は、冷蔵用冷却器８で生成した冷気が流通する冷気通路に相当する。また、冷蔵用冷却器８で生成された冷気は、矢印Ｂで示すように、供給口７ａを介して背面ダクト１７から切替室７の内部に供給されるとともに、切替室７の内部の冷気は、吸出口７ｂを介して冷蔵用冷却器８側に吸い出される。 At this time, the cold air generated by the refrigerating cooler 8 passes through the rear duct 17 formed on the rear side of the duct cover 16 forming the rear wall of the refrigerating chamber 3, as indicated by arrow A, and flows into the refrigerating chamber. 3 and the vegetable compartment 4 before being returned to the cooler unit 10 . The rear duct 17 corresponds to a cool air passage through which cool air generated by the cooler 8 for refrigeration flows. The cold air generated by the refrigerating cooler 8 is supplied to the inside of the switchable chamber 7 from the rear duct 17 through the supply port 7a as indicated by arrow B, and the cold air inside the switchable chamber 7 is , and is sucked out to the refrigerator cooler 8 side through the suction port 7b.

冷蔵用冷却器８は、図２に示すように、平行に配置されたフィンを貫通するパイプを有するフィンチューブ型のものを採用している。この冷蔵用冷却器８は、冷蔵室３や野菜室４といった比較的大容量の貯蔵室に加えて切替室７も冷却する冷気を生成するためにある程度の大きさが必要となること、また、貯蔵室を狭めないようにするために、冷蔵庫１の左右方向に延びて形成されている。以下、冷蔵用冷却器８の冷蔵庫１の左右方向に延びている向きを、長手方向とも称する。 As shown in FIG. 2, the refrigerating cooler 8 is of a fin-tube type having pipes passing through fins arranged in parallel. This refrigerating cooler 8 is required to have a certain size in order to generate cold air for cooling not only relatively large-capacity storage compartments such as the refrigerating compartment 3 and the vegetable compartment 4 but also the switching compartment 7. In order not to narrow the storage compartment, it is formed so as to extend in the horizontal direction of the refrigerator 1. - 特許庁Hereinafter, the direction in which the refrigerating cooler 8 extends in the horizontal direction of the refrigerator 1 is also referred to as the longitudinal direction.

この冷蔵用冷却器８の上方には、長手方向に沿って、複数ここでは２つのファン９ａおよびファン９ｂが、送風面が上向きとなるように配置されている。これら冷蔵用冷却器８、ファン９ａおよびファン９ｂは、ホルダ１８に固定されて冷却器ユニット１０を構成している。 Above the cooler 8 for refrigeration, a plurality of fans 9a and 9b, here two, are arranged along the longitudinal direction so that the air blowing surface faces upward. The cooler 8 for refrigeration, the fan 9a and the fan 9b are fixed to a holder 18 to form a cooler unit 10. As shown in FIG.

また、冷却器ユニット１０の上方つまりは冷蔵用冷却器８、ファン９ａおよびファン９ｂの上方には、モータダンパ１１が設けられている。モータダンパ１１は、周知のようにモータにより開閉板を駆動することにより、ここでは冷気の流路を開閉するものである。本実施形態の場合、モータダンパ１１は、冷蔵用冷却器８と背面ダクト１７との間を概ね閉鎖する大きさの本体部２０に、供給口７ａから供給される冷気の流路を開閉する供給側開閉板２１ａ、吸出口７ｂから吸い出される冷気の流路を開閉する吸出側開閉板２１ｂ、および、冷蔵室３側へ供給される冷気の流路を開閉する冷蔵側開閉板２１ｃが設けられている。 A motor damper 11 is provided above the cooler unit 10, that is, above the refrigerator 8, the fan 9a, and the fan 9b. As is well known, the motor damper 11 opens and closes the cold air flow path by driving an opening/closing plate with a motor. In the case of this embodiment, the motor damper 11 is a supply-side damper that opens and closes a flow path of cold air supplied from the supply port 7 a to the main body 20 having a size that substantially closes the gap between the refrigerating cooler 8 and the rear duct 17 . An opening/closing plate 21a, a suction-side opening/closing plate 21b for opening and closing the passage of cold air sucked from the suction port 7b, and a refrigerator-side opening/closing plate 21c for opening and closing the passage of cold air supplied to the refrigerator compartment 3 are provided. there is

これら供給側開閉板２１ａ、吸出側開閉板２１ｂおよび冷蔵側開閉板２１ｃは、それぞれ本体部２０に形成されている３つの開口部２２ａ、開口部２２ｂおよび開口部２２ｃを開閉する。このとき、ファン９ａは、開口部２２ｃ寄りに配置されており、ファン９ｂは、開口部２２ａ、開口部２２ｂ寄りに設けられている。 These supply-side opening/closing plate 21a, suction-side opening/closing plate 21b, and refrigerator-side opening/closing plate 21c open and close three openings 22a, 22b, and 22c formed in main body 20, respectively. At this time, the fan 9a is arranged near the opening 22c, and the fan 9b is provided near the opening 22a and the opening 22b.

このうち、開口部２２ａおよび開口部２２ｃは、背面ダクト１７に冷気を通すためのものである。つまり、供給側開閉板２１ａは、開口部２２ａから供給口７ａまでの流路を開閉するものであり、吸出側開閉板２１ｂは、吸出口７ｂから開口部２２ｂまでの流路を開閉するものである。また、開口部２２ｃは、切替室７から吸い出した冷気を冷蔵用冷却器８側に戻すためのものである。つまり、冷蔵側開閉板２１ｃは、開口部２２ｃから冷蔵室３側までの流路を開閉するものである。 Of these, the opening 22a and the opening 22c are for letting cold air pass through the rear duct 17. As shown in FIG. That is, the supply side opening/closing plate 21a opens and closes the flow path from the opening 22a to the supply port 7a, and the suction side opening/closing plate 21b opens and closes the flow path from the suction port 7b to the opening 22b. be. Further, the opening 22c is for returning the cool air sucked out from the switching chamber 7 to the refrigerator cooler 8 side. That is, the refrigerating side opening/closing plate 21c opens and closes the flow path from the opening 22c to the refrigerating compartment 3 side.

このため、供給側開閉板２１ａを開放状態とした場合には背面ダクト１７から切替室７の内部への冷気の供給が可能になる一方、供給側開閉板２１ａを閉鎖状態とした場合には背面ダクト１７から切替室７の内部への冷気の供給が不可能になる。この図２では供給側開閉板２１ａが開放状態である態様を示しているが、供給側開閉板２１ａは、図示しない軸部を中心にして回動可能であり、冷蔵庫１の背面側に回転することで、開口部２２ａを閉鎖する。これは、吸出側開閉板２１ｂおよび冷蔵側開閉板２１ｃも同様である。 Therefore, when the supply side opening/closing plate 21a is opened, cold air can be supplied from the rear duct 17 to the interior of the switching chamber 7, while when the supply side opening/closing plate 21a is closed, the rear side is closed. Cool air cannot be supplied from the duct 17 to the interior of the switching chamber 7 . Although FIG. 2 shows a mode in which the supply side opening/closing plate 21a is in an open state, the supply side opening/closing plate 21a is rotatable around a shaft portion (not shown) and rotates toward the back side of the refrigerator 1. Thus, the opening 22a is closed. The same applies to the suction side opening/closing plate 21b and the refrigerator side opening/closing plate 21c.

また、吸出側開閉板２１ｂを開放状態とした場合には切替室７の内部から冷蔵用冷却器８側への冷気の吸い出しが可能になる一方、吸出側開閉板２１ｂを閉鎖状態とした場合には切替室７の内部から冷蔵用冷却器８側への冷気の吸い出しは不可能になる。また、冷蔵側開閉板２１ｃを開放状態とした場合には背面ダクト１７から冷蔵室３および野菜室４への冷気の供給が可能になる一方、冷蔵側開閉板２１ｃを閉鎖状態とした場合には背面ダクト１７から冷蔵室３および野菜室４への冷気の供給が不可能になる。 Further, when the suction side opening/closing plate 21b is opened, cold air can be sucked from the inside of the switching chamber 7 toward the refrigerating cooler 8, whereas when the suction side opening/closing plate 21b is closed. , it becomes impossible to suck out cold air from the interior of the switching chamber 7 to the cooler 8 side for refrigerating. When the refrigerating side opening/closing plate 21c is opened, cold air can be supplied from the rear duct 17 to the refrigerator compartment 3 and the vegetable compartment 4. On the other hand, when the refrigeration side opening/closing plate 21c is closed, Cold air cannot be supplied from the rear duct 17 to the refrigerator compartment 3 and the vegetable compartment 4.

そして、モータダンパ１１は、供給側開閉板２１ａ、吸出側開閉板２１ｂおよび冷蔵側開閉板２１ｃの開閉状態を、１つのモータにより、開放状態を同期させて制御している。ここで、開閉状態を同期させるとは、供給側開閉板２１ａが開放状態にあるときには吸出側開閉板２１ｂも開放状態であり、供給側開閉板２１ａが閉鎖状態にあるときには吸出側開閉板２１ｂも閉鎖状態であることを意味している。 The motor damper 11 controls the opening/closing states of the supply-side opening/closing plate 21a, the suction-side opening/closing plate 21b, and the refrigerator-side opening/closing plate 21c by synchronizing the open states with one motor. Synchronizing the opening/closing states means that when the supply side opening/closing plate 21a is in the open state, the suction side opening/closing plate 21b is also in the open state, and when the supply side opening/closing plate 21a is in the closed state, the suction side opening/closing plate 21b is also opened. It means closed.

次に、上記した冷蔵庫１の作用について説明する。
前述のように、従来では、切替室７を異なる温度帯に切り替え可能とするために複数のダンパを設けていた。その結果、温度を制御するための機構が大型化して設置スペースが増え、貯蔵室の大容量化を阻害する要因となっていた。 Next, the operation of the refrigerator 1 described above will be described.
As described above, conventionally, a plurality of dampers are provided in order to switch the switching chamber 7 between different temperature zones. As a result, the size of the mechanism for controlling the temperature has increased, and the installation space has increased, which has been a factor hindering the increase in the capacity of the storage room.

そこで、本実施形態の冷蔵庫１は、１つのモータダンパ１１により、冷蔵室３と切替室７との間の冷気の流れ、および、切替室７の冷気の供給と吸い出しとにおける冷気の流れを調整可能としている。 Therefore, in the refrigerator 1 of the present embodiment, one motor damper 11 can adjust the flow of cool air between the refrigerator compartment 3 and the switchable compartment 7 and the flow of cool air in the supply and suction of cool air from the switchable compartment 7 . and

具体的には、モータダンパ１１は、モータを回転させることにより、供給側開閉板２１ａと吸出側開閉板２１ｂの開閉状態を制御する。このとき、モータダンパ１１は、供給側開閉板２１ａと吸出側開閉板２１ｂとの開閉状態を切り替えるタイミングを同期させている。具体的には、モータダンパ１１は、切替室７に関して、供給側開閉板２１ａおよび吸出側開閉板２１ｂを、以下の２つの状態に制御する。 Specifically, the motor damper 11 controls the opening/closing state of the supply side opening/closing plate 21a and the suction side opening/closing plate 21b by rotating the motor. At this time, the motor damper 11 synchronizes the timing of switching the opening/closing state of the supply side opening/closing plate 21a and the suction side opening/closing plate 21b. Specifically, the motor damper 11 controls the supply side opening/closing plate 21a and the suction side opening/closing plate 21b with respect to the switching chamber 7 in the following two states.

・供給側開閉板２１ａを開放状態、吸出側開閉板２１ｂを開放状態
・供給側開閉板２１ａを閉鎖状態、吸出側開閉板２１ｂを閉鎖状態
つまり、モータダンパ１１は、供給側開閉板２１ａと吸出側開閉板２１ｂの開閉状態を同期させている。 ・The supply side opening/closing plate 21a is in an open state, and the suction side opening/closing plate 21b is in an open state. ・The supply side opening/closing plate 21a is in a closed state, and the suction side opening/closing plate 21b is in a closed state. The opening/closing state of the opening/closing plate 21b is synchronized.

また、モータダンパ１１は、上記の２つの状態を、冷蔵側開閉板２１ｃの開放状態に対応させて制御している。このため、このため、モータダンパ１１は、本実施形態では以下の４つの開閉状態（Ｓ１～Ｓ４）が切り替えられることになる。なお、以下では、開放状態を「開」、閉鎖状態を「閉」と示している。 Further, the motor damper 11 controls the above two states in correspondence with the open state of the refrigerator-side opening/closing plate 21c. Therefore, in this embodiment, the motor damper 11 is switched between the following four open/closed states (S1 to S4). In addition, below, an open state is shown as "open", and a closed state is shown as "closed."

Ｓ１：供給側開閉板２１ａ：開、吸出側開閉板２１ｂ：開、冷蔵側開閉板２１ｃ：開
Ｓ２：供給側開閉板２１ａ：閉、吸出側開閉板２１ｂ：閉、冷蔵側開閉板２１ｃ：開
Ｓ３：供給側開閉板２１ａ：開、吸出側開閉板２１ｂ：開、冷蔵側開閉板２１ｃ：閉
Ｓ４：供給側開閉板２１ａ：閉、吸出側開閉板２１ｂ：閉、冷蔵側開閉板２１ｃ：閉 S1: Supply side opening/closing plate 21a: Open, Suction side opening/closing plate 21b: Open, Refrigeration side opening/closing plate 21c: Open S2: Supply side opening/closing plate 21a: Closed, Suction side opening/closing plate 21b: Closed, Refrigeration side opening/closing plate 21c: Open S3: Supply side opening/closing plate 21a: Open, Suction side opening/closing plate 21b: Open, Refrigeration side opening/closing plate 21c: Closed S4: Supply side opening/closing plate 21a: Closed, Suction side opening/closing plate 21b: Closed, Refrigeration side opening/closing plate 21c: Closed

このとき、これらの開閉状態の切り替えは、１つのモータを回転させることによって機械的に行われる。なお、機械的に切り替える機構についてはギアやカムあるいはラック等の機械部品の組み合わせにより実現できるため詳細な説明は省略するが、冷蔵側開閉板２１ｃについてはモータの回転範囲の１／２の範囲で冷蔵側開閉板２１ｃが開放状態となり、残りの１／２の範囲で冷蔵側開閉板２１ｃが閉鎖状態になるようにし、供給側開閉板２１ａおよび吸出側開閉板２１ｂについては、互いの軸部を連結した状態で１／４回転ごとに開放状態と閉鎖状態とが切り替わるようにすることで実現できる。 At this time, switching between these open and closed states is mechanically performed by rotating one motor. Since the mechanical switching mechanism can be realized by combining mechanical parts such as gears, cams, racks, etc., a detailed description will be omitted. The refrigerating side opening/closing plate 21c is opened, and the remaining 1/2 of the refrigeration side opening/closing plate 21c is closed. It can be realized by switching between the open state and the closed state every 1/4 turn in the connected state.

そして、Ｓ１の開閉状態では、冷蔵室３側と切替室７との双方に冷気が流れることから、例えば切替室７の設定温度が冷蔵室３の温度に近い場合等において冷蔵室３側と切替室７との双方を効率よく冷却することが可能になる。
また、Ｓ２の開閉状態では、冷蔵室３側にのみ冷気が流れることから、例えば切替室７の設定温度が冷蔵室３の温度より低い場合等において、冷蔵室３側を冷却するための冷気が切替室７に侵入して設定温度よりも高くなってしまうこと等を防止することが可能となる。 In the open/closed state of S1, cold air flows to both the refrigerating chamber 3 side and the switching chamber 7. Therefore, for example, when the set temperature of the switching chamber 7 is close to the temperature of the refrigerating chamber 3, switching to the refrigerating chamber 3 side is performed. It becomes possible to cool both the chamber 7 efficiently.
In addition, in the open/closed state of S2, cold air flows only to the refrigerator compartment 3 side. It is possible to prevent the temperature from entering the switching chamber 7 and becoming higher than the set temperature.

また、Ｓ３の開閉状態では、冷蔵室３側には冷気が流れないことから、例えば切替室７の設定温度が冷蔵室３の温度より低い場合等において、冷蔵室３側を過度に冷却することなく切替室７を設定温度に制御すること等が可能となる。
また、Ｓ４の開閉状態では、冷蔵室３側にも切替室７にも冷気が流れないことから、例えば冷蔵用冷却器８を除霜する際にヒータによって加熱された空気が貯蔵室側に流れ込むことを防止すること等が可能になる。
このように、冷蔵庫１は、１つのモータダンパ１１により、冷気を生成する冷却器と、切替室７と他の貯蔵室との間の冷気の流れを調整可能としている。 In addition, in the open/closed state of S3, cold air does not flow to the refrigerator compartment 3 side. It is possible to control the switching chamber 7 to the set temperature without any need.
In the open/closed state of S4, cold air does not flow into the refrigerating compartment 3 or the switching compartment 7, so that air heated by the heater flows into the storage compartment when defrosting the refrigerating cooler 8, for example. It is possible to prevent
In this way, the refrigerator 1 can adjust the flow of cool air between the cooler that generates cool air and the switchable compartment 7 and other storage compartments using one motor damper 11 .

以上説明した冷蔵庫１によれば、次のような効果を得ることができる。
冷蔵庫１は、冷気を生成する冷却器としての冷蔵用冷却器８と、冷蔵用冷却器８で生成した冷気が流通する冷気通路としての背面ダクト１７と、設定温度を切り替え可能に設けられている貯蔵室であって、背面ダクト１７から内部に冷気が供給される供給口７ａと、内部から冷蔵用冷却器８側に冷気が吸い出される吸出口７ｂとが形成されている切替室７と、供給口７ａから供給される冷気の流路を開閉する供給側開閉板２１ａ、および吸出口７ｂから吸い出される冷気の流路を開閉する吸出側開閉板２１ｂを有し、１つのモータにより供給側開閉板２１ａおよび吸出側開閉板２１ｂの双方の開閉状態を切り替えるモータダンパ１１と、を備える。 According to the refrigerator 1 described above, the following effects can be obtained.
The refrigerator 1 is provided with a refrigerating cooler 8 as a cooler that generates cool air, a rear duct 17 as a cold air passage through which the cool air generated by the refrigerating cooler 8 is circulated, and a set temperature that can be switched. A switchable chamber 7 which is a storage chamber and is formed with a supply port 7a for supplying cool air to the inside from a rear duct 17 and a suction port 7b for sucking the cold air from the inside toward the refrigerating cooler 8 side; It has a supply side opening/closing plate 21a that opens and closes the flow path of cool air supplied from the supply port 7a, and a suction side opening/closing plate 21b that opens and closes the flow path of cool air sucked out from the suction port 7b. and a motor damper 11 for switching the open/close state of both the opening/closing plate 21a and the suction side opening/closing plate 21b.

このような構成によれば、切替室７には供給口７ａと吸出口７ｂとを設けていることから、切替室７への冷気の供給と吸い出しとが可能となり、切替室７をより精度良く設定温度に制御することができるとともに、１つのモータにより供給側開閉板２１ａおよび吸出側開閉板２１ｂの双方の開閉状態を切り替えることから、温度を制御するための機構が大型化することが抑制される。したがって、温度を制御するための機構を大型化することなく、複数の温度帯に切り替え可能な切替室７の温度を精度良く設定温度となるように制御することができる。 According to such a configuration, since the switchable chamber 7 is provided with the supply port 7a and the suction port 7b, it is possible to supply and suck cool air to and from the switchable chamber 7, so that the switchable chamber 7 can be operated more accurately. Since the temperature can be controlled to the set temperature and the opening/closing state of both the supply side opening/closing plate 21a and the suction side opening/closing plate 21b can be switched by one motor, the mechanism for controlling the temperature can be prevented from becoming large. be. Therefore, the temperature of the switching chamber 7 capable of switching between a plurality of temperature zones can be accurately controlled to the set temperature without increasing the size of the mechanism for controlling the temperature.

また、冷蔵庫１は、モータダンパ１１により、供給側開閉板２１ａおよび吸出側開閉板２１ｂの開閉状態を同期させて制御する。これにより、供給側開閉板２１ａおよび吸出側開閉板２１ｂという２つの冷気の流路を開閉するための開閉板を、１つのモータダンパ１１で開放状態または閉鎖状態とすることができ、開閉状態の切り替えを容易に行うことができるとともに、機構の大型化を抑制することができる。 In addition, the refrigerator 1 synchronizes and controls the opening/closing states of the supply side opening/closing plate 21a and the suction side opening/closing plate 21b by the motor damper 11 . As a result, the opening/closing plates for opening and closing the two cold air flow paths, namely, the supply side opening/closing plate 21a and the suction side opening/closing plate 21b, can be opened or closed by the single motor damper 11, thereby switching the opening/closing state. can be easily performed, and an increase in the size of the mechanism can be suppressed.

また、冷蔵庫１は、冷蔵用冷却器８の上部に配置されるモータダンパ１１に、背面ダクト１７に冷気を通すための複数の開口部２２ａ、開口部２２ｃを設けている。より具体的には、モータダンパ１１には、主として切替室７に冷気を流すための開口部２２ａと、主として冷蔵室３や野菜室４等の他の貯蔵室に冷気を流すための開口部２２ｃとが形成されている。これにより、切替室７と他の貯蔵室との間で冷気の流れを個別に制御することができる。 In the refrigerator 1 , the motor damper 11 arranged above the cooler 8 for refrigeration is provided with a plurality of openings 22 a and 22 c for passing cool air through the rear duct 17 . More specifically, the motor damper 11 has an opening 22a through which cool air flows mainly to the switching compartment 7, and an opening 22c through which cool air flows mainly to other storage compartments such as the refrigerator compartment 3 and the vegetable compartment 4. is formed. Thereby, the flow of cool air can be individually controlled between the switching compartment 7 and the other storage compartments.

また、冷蔵庫１は、冷蔵温度帯の冷気を生成する冷蔵用冷却器８と、冷凍温度帯の冷気を生成する冷凍用冷却器１２と、を備え、切替室７は、冷蔵用冷却器８で生成された冷気が供給される貯蔵室であり、モータダンパ１１は、冷蔵用冷却器８に設けられている。 The refrigerator 1 also includes a refrigerating cooler 8 that generates cold air in a refrigerating temperature range and a freezing cooler 12 that generates cold air in a freezing temperature range. It is a storage room to which the generated cool air is supplied, and the motor damper 11 is provided in the cooler 8 for refrigeration.

冷蔵用冷却器８は、冷凍用冷却器１２に比べて蒸発温度が高いため、除霜時の温度上昇を冷凍用冷却器１２に比べて抑えることが可能であり、除霜によって貯蔵室の温度が上昇してしまうことを抑制することができる。 Since the refrigerating cooler 8 has a higher evaporation temperature than the freezing cooler 12, it is possible to suppress the temperature rise during defrosting compared to the freezing cooler 12, and defrosting reduces the temperature of the storage compartment. rise can be suppressed.

また、冷蔵庫１は、冷蔵用冷却器８の上方に、長手方向に配置されている複数のファン９ａ、９ｂを備える。そして、実施形態では、ファン９ａは開口部２２ｃ寄りに配置されており、ファン９ｂは開口部２２ａ、開口部２２ｂ寄りに設けられている。このため、ファン９ａとファン９ｂの回転数を制御することにより、冷蔵室３側と切替室７側との風量を調整することが可能となり、切替室７も含めて各貯蔵室の温度を詳細且つ精度良く制御することができる。 The refrigerator 1 also includes a plurality of fans 9a and 9b arranged in the longitudinal direction above the cooler 8 for refrigeration. In the embodiment, the fan 9a is arranged near the opening 22c, and the fan 9b is provided near the opening 22a and the opening 22b. Therefore, by controlling the number of revolutions of the fans 9a and 9b, it is possible to adjust the air volume of the refrigerating compartment 3 side and the switching compartment 7 side. And it can be controlled with high precision.

また、冷蔵庫１は、ファン９ａ、ファン９ｂを送風面が上向きに配置している。これにより、冷蔵用冷却器８からの冷気の流れる方向、つまりは、背面ダクト１７に沿った上下方向への空気の流れが生じ、冷気の循環効率を上げることができる。実施形態では供給側開閉板２１ａおよび吸出側開閉板２１ｂの開閉状態を同期させた例を示したが、同期させることなく、個別に制御することもできる。また、供給側開閉板２１ａの開閉状態、吸出側開閉板２１ｂの開閉状態、および冷蔵側開閉板２１ｃの開閉状態を個別に制御することもできる。その場合、１つのモータダンパ１１により個別に制御することで実施形態と同様の効果を得ることができる。 Further, in the refrigerator 1, the fan 9a and the fan 9b are arranged with their blowing surfaces facing upward. As a result, the direction in which cool air flows from the refrigerating cooler 8, that is, the air flows in the vertical direction along the rear duct 17, and the circulation efficiency of cool air can be increased. In the embodiment, an example in which the open/closed states of the supply side opening/closing plate 21a and the suction side opening/closing plate 21b are synchronized is shown, but they can be individually controlled without synchronization. Further, the opening/closing state of the supply-side opening/closing plate 21a, the opening/closing state of the suction-side opening/closing plate 21b, and the opening/closing state of the refrigerator-side opening/closing plate 21c can be individually controlled. In that case, the same effects as those of the embodiment can be obtained by controlling individually by one motor damper 11 .
