Description
本発明は、冷蔵保存庫に関し、詳しくは、例えば食品などの鮮度を長期間維持することができる冷蔵保存庫に関する。 The present invention relates to a refrigerating storage cabinet, and more particularly to a refrigerating storage cabinet capable of maintaining the freshness of foods for a long period of time.
野菜などの食品を長期間保存するために、食品を冷凍することが行われている。しかしながら、冷凍すると、食品の細胞が破壊され、解凍した際には、鮮度が著しく低下する。そこで、従来より、庫内に高電圧を付加して電圧振動により静電場雰囲気を形成し、該庫内の食品などを静電場雰囲気の中で冷蔵することにより、冷蔵室内の温度を氷点下数度程度にまで下げても当該冷蔵室内の食品が凍ることを防止できる。これにより、食品の鮮度を長期間に渡って維持することが行われている。 BACKGROUND OF THE INVENTION Food products such as vegetables are frozen for long-term storage. However, when frozen, the cells of the food are destroyed and, when thawed, the freshness is significantly reduced. Therefore, conventionally, a high voltage is applied to the refrigerator to form an electrostatic field atmosphere by voltage vibration, and the food in the refrigerator is refrigerated in the electrostatic field atmosphere so that the temperature in the refrigerating room is several degrees below the freezing point. Even if it is lowered to a certain degree, it is possible to prevent the food in the refrigerating room from freezing. As a result, the freshness of food is maintained for a long period of time.
このような食品の冷蔵保存庫としては、例えば、特許文献１および２に記載のようなものがある。特許文献１および２に記載の冷蔵保存庫は、比較的小型であり、庫内に高電圧を付加して静電場雰囲気を形成する１台の電圧印加装置と、この電圧印加装置に電圧を供給する１つの電圧発生装置とを備えた構成となっている。 Examples of such refrigerated storage of foods include those described in Patent Documents 1 and 2. The refrigerating storage cabinets described in Patent Documents 1 and 2 are relatively small in size, and a single voltage applying device that applies a high voltage to the interior of the refrigerator to form an electrostatic field atmosphere, and a voltage is supplied to the voltage applying device. And a single voltage generator that operates.
ところで、比較的大型の冷蔵保存庫の場合は、その容積が大きいため、複数の電圧印加装置を備える必要があった。このため、従来は、電圧印加装置に安定的に高電圧の交流電圧を供給するために、これら複数の電圧印加装置に対応して複数の電圧発生装置を備えるようにしていた。 By the way, in the case of a relatively large refrigerated storage, since its volume is large, it is necessary to provide a plurality of voltage applying devices. Therefore, conventionally, in order to stably supply a high-voltage AC voltage to the voltage applying device, a plurality of voltage generating devices have been provided corresponding to the plurality of voltage applying devices.
しかしながら、複数の電圧印加装置に対応して複数の電圧発生装置を備える構成にした場合、消費電力が極めて大きくなる欠点があった。 However, when a plurality of voltage generators are provided corresponding to a plurality of voltage application devices, there is a drawback that the power consumption becomes extremely large.
本発明は上述の点に鑑みてなされたものであり、その目的は、比較的大型の冷蔵保存庫の場合でも、消費電力を抑えることができる冷蔵保存庫を提供することにある。 The present invention has been made in view of the above points, and an object of the present invention is to provide a refrigerating storage cabinet capable of suppressing power consumption even in the case of a relatively large refrigerating storage cabinet.
上記課題を解決するため、本発明に係る冷蔵保存庫は、冷蔵室（２）内に高電圧を付加して静電場雰囲気を形成する複数の電圧印加装置（３）と、前記複数の電圧印加装置（３）に電圧を供給する１つの電圧発生装置（４）と、前記電圧発生装置（４）と前記複数の電圧印加装置（３）それぞれとの間の電気的接続を順次に切り替える接続制御装置（５）とを備えた構成としている。 In order to solve the above problems, a refrigerating storage cabinet according to the present invention comprises a plurality of voltage applying devices (3) for applying a high voltage in a refrigerating room (2) to form an electrostatic field atmosphere, and the plurality of voltage applying devices. One voltage generator (4) for supplying a voltage to the device (3), and connection control for sequentially switching electrical connections between the voltage generator (4) and each of the plurality of voltage applying devices (3). And a device (5).
また、前記接続制御装置（５）は、前記電圧発生装置（４）で発生した電圧を加える前記電圧印加装置（３）を一定間隔で順次に切り替えるように構成してもよい。 Further, the connection control device (5) may be configured to sequentially switch the voltage application device (3) that applies the voltage generated by the voltage generation device (4) at regular intervals.
さらに、本発明では、前記電圧発生装置（４）を、２５００Ｖ〜７０００Ｖの交流電圧を発生する装置としてもよい。 Furthermore, in the present invention, the voltage generator (4) may be a device that generates an alternating voltage of 2500V to 7000V.
本発明にかかる冷蔵保存庫によれば、冷蔵室内に高電圧を付加して静電場雰囲気を形成する複数の電圧印加装置と、複数の電圧印加装置に電圧を供給する１つの電圧発生装置と、電圧発生装置と前記複数の電圧印加装置それぞれとの間の電気的接続を順次切り替える接続制御装置とを備えた構成としたことにより、１台の電圧発生装置を備えるだけで済み、消費電力も電圧発生装置１台分で済むので、消費電力の大幅な低減を図ることができる。 According to the refrigerating and storing cabinet according to the present invention, a plurality of voltage applying devices that apply a high voltage to the refrigerating chamber to form an electrostatic field atmosphere, and one voltage generating device that supplies a voltage to the plurality of voltage applying devices, With the configuration including the connection control device that sequentially switches the electrical connection between the voltage generation device and each of the plurality of voltage application devices, only one voltage generation device is required and the power consumption is reduced. Since one generator is sufficient, it is possible to significantly reduce power consumption.
