本開示は、放電極である霧化電極への水の供給を継続して、素早くミストを供給することができる冷蔵庫を提供する。 The present disclosure provides a refrigerator capable of continuously supplying water to the atomization electrode, which is a discharge electrode, and quickly supplying mist.

本開示における冷蔵庫は、冷蔵室に、高電圧をかけて水を霧化させる静電霧化装置を備えた冷蔵庫において、前記静電霧化装置は、霧化電極と前記霧化電極に対向する対向電極と前記霧化電極の冷却を行うペルチェ素子とを有し、前記冷蔵室の設定温度範囲と前記冷蔵室の湿度とに基づいて、前記霧化電極が露点温度以下となるように、前記ペルチェ素子への通電電流値を設定したこと、を備える。 The refrigerator in the present disclosure is a refrigerator provided with an electrostatic atomizer in which a high voltage is applied to atomize water in a refrigerator, and the electrostatic atomizer faces the atomizing electrode and the atomizing electrode.

（実施の形態１）
図１は冷蔵庫の正面図、図２は縦断面図である。図１、図２を用いて冷蔵庫の全体構成を説明する。 (Embodiment 1)
FIG. 1 is a front view of the refrigerator, and FIG. 2 is a vertical sectional view. The overall configuration of the refrigerator will be described with reference to FIGS. 1 and 2.

本実施の形態に係る冷蔵庫１は、前方を開口した冷蔵庫本体２を備え、この冷蔵庫本体２は外郭を構成する金属製の外板３と、硬質樹脂製の内板４と、前記外板３および内板４の間に発泡充填された断熱材５とで構成してあり、断熱仕切板６、７、８によって複数の貯蔵室が形成してある。また、冷蔵庫本体２の各貯蔵室は冷蔵庫本体２と同様の断熱構成を採用した回動式の扉９或いは引出し式の扉１０、１１、１２、１３で開閉自在としてある。 The refrigerator 1 according to the present embodiment includes a refrigerator main body 2 having an open front, and the refrigerator main body 2 includes a metal outer plate 3 constituting an outer shell, an inner plate 4 made of hard resin, and the outer plate 3. It is composed of a heat insulating material 5 which is foam-filled between the inner plates 4 and a plurality of storage chambers are formed by the heat insulating partition plates 6, 7, and 8. Further, each storage room of the refrigerator main body 2 is openable and closable by a rotary door 9 or a drawer type door 10, 11, 12, 13 which adopts the same heat insulating structure as the refrigerator main body 2.

冷蔵庫本体２内には、最上部に冷蔵室１４を有し、冷蔵室１４と断熱仕切板６で上下に区画され、断熱仕切板６の下方に設けた温度帯切り替え可能な切替室１５と、切替室１５の横に断熱区画して設けた製氷室１６と、切替室１５および製氷室１６と断熱仕切板７で上下に区画され、断熱仕切板７の下方に設けた野菜室１７と、さらに野菜室１７と断熱仕切板８で上下に区画され、断熱仕切板７の下方に設けた冷凍室１８を備えている。 In the refrigerator main body 2, a refrigerating chamber 14 is provided at the uppermost portion, and the refrigerating chamber 14 and the heat insulating partition plate 6 are vertically partitioned, and a temperature zone switchable switching chamber 15 provided below the heat insulating partition plate 6 is provided. An ice making chamber 16 provided next to the switching chamber 15 with a heat insulating partition, a vegetable chamber 17 provided above and below the switching chamber 15, the ice making chamber 16 and a heat insulating partition plate 7 and further provided below the heat insulating partition plate 7. It is divided into upper and lower parts by a vegetable compartment 17 and a heat insulating partition plate 8, and has a freezing chamber 18 provided below the heat insulating partition plate 7.

そして、冷蔵室１４には複数の棚板１９が上下複数段となって設けてあり、冷蔵室１４の下部には冷蔵室１４と冷却温度帯の異なるパーシャル室２０が形成されている。 A plurality of shelf boards 19 are provided in the refrigerating chamber 14 in a plurality of upper and lower stages, and a partial chamber 20 having a different cooling temperature zone from the refrigerating chamber 14 is formed below the refrigerating chamber 14.

冷蔵室１４は、冷蔵保存するための貯蔵室で、具体的には、約２～３℃に設定され冷却される。また、冷蔵室１４内に設けたパーシャル室２０は微凍結保存に適した約－３℃に設定され、パーシャル室２０は１℃前後のチルド温度帯にも温度設定が可能である。 The refrigerating chamber 14 is a storage chamber for refrigerating and storing, and specifically, it is set to about 2 to 3 ° C. and cooled. Further, the partial chamber 20 provided in the refrigerating chamber 14 is set to about -3 ° C, which is suitable for microfreezing storage, and the partial chamber 20 can be set to a temperature in a chilled temperature zone of around 1 ° C.

野菜室１７は、冷蔵室１４より若干高く温度設定される貯蔵室で、具体的には、４～７℃に設定され冷却される。この野菜室１７は野菜等の収納食品から発せられる水分により高湿度となるため、局所的に冷えすぎると結露することがある。そのため、比較的高い温度に設定することで冷却量を少なくし、局所的な冷えすぎによる結露発生を抑制している。 The vegetable compartment 17 is a storage chamber whose temperature is set slightly higher than that of the refrigerating chamber 14, and specifically, the temperature is set to 4 to 7 ° C. for cooling. Since the vegetable chamber 17 becomes highly humid due to the moisture emitted from the stored food such as vegetables, dew condensation may occur if it is locally too cold. Therefore, by setting the temperature to a relatively high temperature, the amount of cooling is reduced and the generation of dew condensation due to local overcooling is suppressed.

冷凍室１８は、冷凍温度帯に設定される貯蔵室で、通常約－１８℃に設定され冷却されるが、冷凍保存状態向上のため、例えば－３０℃や－２５℃などの低温に設定され冷却されることもある。 The freezing chamber 18 is a storage chamber set in the freezing temperature zone, and is usually set to about -18 ° C and cooled, but is set to a low temperature such as -30 ° C or -25 ° C in order to improve the freezing storage state. It may be cooled.

切替室１５は、庫内の温度が変更可能な貯蔵室であり、用途に応じて冷蔵温度帯から冷凍温度帯まで切り換えることができるようになっている。 The switching chamber 15 is a storage chamber in which the temperature inside the refrigerator can be changed, and can be switched from the refrigerating temperature zone to the freezing temperature zone according to the application.

また、野菜室１７の背面には冷却室２１が設けてあり、この冷却室２１には冷気を生成する冷却器２２と、冷気を各室に供給する冷却ファン２３とが設置してある。そして更に冷却器２２の下方にはガラス管ヒータ等で構成した除霜手段２４（以下、ヒータと称す）が設けてある。 Further, a cooling chamber 21 is provided on the back surface of the vegetable compartment 17, and a cooler 22 for generating cold air and a cooling fan 23 for supplying cold air to each chamber are installed in the cooling chamber 21. Further, below the cooler 22, a defrosting means 24 (hereinafter referred to as a heater) composed of a glass tube heater or the like is provided.

冷却器２２は、圧縮機２５と、熱交換器（図示せず）と、各室の開口部の露付きを防止する防露パイプ（図示せず）と、キャピラリーチューブ（図示せず）とを環状に接続して冷凍サイクルを構成しており、圧縮機２５によって圧縮された冷媒の循環によって冷却を行う。 The cooler 22 includes a compressor 25, a heat exchanger (not shown), a dew-proof pipe (not shown) for preventing dew from dew at the openings of each chamber, and a capillary tube (not shown). The refrigeration cycle is formed by connecting them in a ring shape, and cooling is performed by circulating the refrigerant compressed by the compressor 25.

また、冷却ファン２３は冷却器２２の上方に設けてあり、冷却器２２で冷却された一部の冷気が冷却ファン２３による強制通風によって、その下流側に連通する冷蔵室冷気風路２６を通って冷蔵室１４に供給され、また冷却器２２で冷却された一部の冷気が冷却ファン２３の強制通風によって冷凍室冷気風路２７を通って冷凍室１８に供給され、また冷蔵室１４を循環した冷気または冷却器２２で冷却された一部の冷気が野菜室冷気風路(図示しない)を通って野菜室１７に供給されて、これら各室を冷却するようになっている。 Further, the cooling fan 23 is provided above the cooler 22, and a part of the cold air cooled by the cooler 22 passes through the refrigerating chamber cold air passage 26 communicating to the downstream side by the forced ventilation by the cooling fan 23. A part of the cold air cooled by the cooler 22 is supplied to the refrigerating chamber 14 through the freezing chamber cold air passage 27 by the forced ventilation of the cooling fan 23, and is also circulated in the refrigerating chamber 14. The cold air or a part of the cold air cooled by the cooler 22 is supplied to the vegetable chamber 17 through the vegetable chamber cold air passage (not shown) to cool each of these chambers.

また冷蔵室１４と、切替室１５および製氷室とを仕切る断熱仕切板６には冷蔵室１４への冷気量を調節する冷蔵室ダンパ３９が備えられている。 Further, the heat insulating partition plate 6 that separates the refrigerating chamber 14, the switching chamber 15, and the ice making chamber is provided with a refrigerating chamber damper 39 for adjusting the amount of cold air to the refrigerating chamber 14.

次に冷蔵室１４の構成について具体的に説明する。 Next, the configuration of the refrigerating chamber 14 will be specifically described.

図３は冷蔵室１４上方の要部断面図である。図４は部分拡大図で、図５は霧化カバー部材の斜視図である。 FIG. 3 is a cross-sectional view of a main part above the refrigerating chamber 14. FIG. 4 is a partially enlarged view, and FIG. 5 is a perspective view of the atomizing cover member.

冷蔵室１４の内壁を構成する内板４で、その天面部２８には、貯蔵室内にナノサイズのマイナスイオンミストを発生させる静電霧化装置２９が設けられている。静電霧化装置２９は冷蔵室１４内の空気中の水分を結露させる霧化部３０と霧化部３０に高電圧を印加し、後述するペルチェ素子４２に電流を流す回路部３１とを備えている。 An inner plate 4 constituting the inner wall of the refrigerating chamber 14 is provided with an electrostatic atomizer 29 for generating nano-sized negative ion mist in the storage chamber on the top surface portion 28 thereof. The electrostatic atomizer 29 includes an atomizing unit 30 that condenses moisture in the air in the refrigerating chamber 14, and a circuit unit 31 that applies a high voltage to the atomizing unit 30 and causes a current to flow through the Pelche element 42, which will be described later. ing.

霧化部３０はマイナスイオンミストを発生する霧化電極４０と、霧化電極４０に対向配置した対向電極４１とを備えている。霧化電極４０に空気中の水分を供給する供給手段としてペルチェ素子４２とを備えている。回路部３１から熱交換部のペルチェ素子４２へ通電を行い、ペルチェ素子４２内において熱移動が生じ、吸熱側に接続している冷却部を介して霧化電極４０が冷却される。具体的には、冷蔵室１４の湿度が約２０％の低湿度環境では、霧化電極４０は結露しにくい。 The atomizing unit 30 includes an atomizing electrode 40 that generates negative ion mist, and a counter electrode 41 that is arranged to face the atomizing electrode 40. A Pelche element 42 is provided as a supply means for supplying moisture in the air to the atomizing electrode 40. The circuit unit 31 energizes the pelche element 42 of the heat exchange unit, heat transfer occurs in the pelche element 42, and the atomizing electrode 40 is cooled via the cooling unit connected to the endothermic side. Specifically, in a low humidity environment where the humidity of the refrigerating chamber 14 is about 20%, the atomizing electrode 40 is less likely to cause dew condensation.

このため、ペルチェ素子４２による冷却能力を高めるために、霧化部３０に結露を発生させるため、冷蔵室ダンパ３９を閉じて、冷蔵室１４に吐出される冷気を抑えて、ペルチェ素子４２に通電し、冷やしすぎない温度に霧化電極４０を冷却して空気中の水分を付着させ、次にペルチェ素子４２への通電を停止して霧化電極４０が凍結しないようにし、凍結したとしてもすぐに氷を融解して水を生成し、そして最後に霧化電極４０と対向電極４１との間に回路部３１のトランスを介して高電圧を印加するとともに、ペルチェ素子４２への通電を行って霧化させ、ミストを発生する構成となっている。 Therefore, in order to increase the cooling capacity of the Pelche element 42, in order to generate dew on the atomizing portion 30, the refrigerating chamber damper 39 is closed to suppress the cold air discharged to the refrigerating chamber 14, and the Pelche element 42 is energized. Then, the atomization electrode 40 is cooled to a temperature that is not overcooled to allow moisture in the air to adhere to it, and then the energization of the Pelche element 42 is stopped to prevent the atomization electrode 40 from freezing. The ice is melted to generate water, and finally a high voltage is applied between the atomizing electrode 40 and the counter electrode 41 via the transformer of the circuit unit 31, and the Pelche element 42 is energized. It is configured to atomize and generate mist.

また静電霧化装置２９の後方には、冷蔵室１４の背面部には冷蔵室冷気風路２６が設けられている。冷蔵室冷気風路２６は冷蔵室１４の下端部から最上部の棚板１９よりも上方で天面部２８よりも下方の位置まで延在して設けられ、天面部２８に向かって開口した吹出し口２６ａが複数個備えられている。 Further, behind the electrostatic atomizer 29, a refrigerating chamber cold air passage 26 is provided on the back surface of the refrigerating chamber 14. The refrigerating chamber cold air passage 26 extends from the lower end of the refrigerating chamber 14 to a position above the uppermost shelf plate 19 and below the top surface portion 28, and is an outlet that opens toward the top surface portion 28. A plurality of 26a are provided.

天面部２８には冷蔵室１４内を照明するＬＥＤで構成された照明装置３２が設けられ、冷蔵室１４の前面開口部側から順に照明装置３２、静電霧化装置２９が配置している。 A lighting device 32 composed of LEDs for illuminating the inside of the refrigerating chamber 14 is provided on the top surface portion 28, and the lighting device 32 and the electrostatic atomizing device 29 are arranged in order from the front opening side of the refrigerating chamber 14.

静電霧化装置２９と冷蔵室冷気風路２６の吹出し口２６ａとの間にはスペース３３があり、静電霧化装置２９は冷蔵室冷気風路２６よりも照明装置３２に近づけて配置している。 There is a space 33 between the electrostatic atomizer 29 and the outlet 26a of the refrigerating room cold air passage 26, and the electrostatic atomizing device 29 is arranged closer to the lighting device 32 than the refrigerating room cold air passage 26. ing.

冷蔵庫の天面壁を構成する外板２に冷蔵庫の運転を制御する制御基板３４を収納する制御基板収納部３５が形成されており、制御基板収納部３５は天面壁に備えた凹み部に制御基板収納部３５を配置し制御基板３４を収納している。 A control board storage unit 35 for storing a control board 34 for controlling the operation of the refrigerator is formed on the outer plate 2 constituting the top wall of the refrigerator, and the control board storage unit 35 has a control board in a recessed portion provided on the top wall. A storage unit 35 is arranged to store the control board 34.

静電霧化装置２９は、冷蔵室１４の開口部よりも壁厚が薄くなった制御基板３４の下方に配置されている。 The electrostatic atomizer 29 is arranged below the control board 34 whose wall thickness is thinner than that of the opening of the refrigerating chamber 14.

また霧化カバー部材３７は天面部２８から最上部の棚板１９に向かって突出して形成され、霧化カバー部材３７の側面部３７ｄには上下方向に複数段のミスト放出口３７ｅが形成され、ミストを放出できるように構成されている。また下段へ行くほどミスト放出口３７ｅの位置が霧化部３０または回路部３１に近づくように段差状に形成され、上下方向の隣り合うミスト放出口３７ｅ間にはガイドリブ３７ｆが形成され、霧化カバー部材３７の前に食品等を置かれてもミスト放出口３７ｅが塞がれないように構成されている。 Further, the atomization cover member 37 is formed so as to project from the top surface portion 28 toward the uppermost shelf plate 19, and a plurality of stages of mist discharge ports 37e are formed in the vertical direction on the side surface portion 37d of the atomization cover member 37. It is configured to release mist. Further, the mist discharge port 37e is formed in a stepped shape so as to approach the atomization section 30 or the circuit section 31 toward the lower stage, and a guide rib 37f is formed between the adjacent mist discharge ports 37e in the vertical direction to atomize. The mist discharge port 37e is configured so as not to be blocked even if food or the like is placed in front of the cover member 37.

したがって、食品等が詰め込まれても、ミスト放出口３７ｅからミストを放出することができ、ミスト中に含まれるＯＨラジカルが各種の臭い成分を分解して、冷蔵室１４内の除菌および脱臭効果を維持することができる。 Therefore, even if food or the like is packed, the mist can be released from the mist discharge port 37e, and the OH radicals contained in the mist decompose various odorous components to disinfect and deodorize the refrigerating chamber 14. Can be maintained.

また霧化カバー部材３７の底面部は冷蔵室１４の前面開口部に向かって上方に傾斜して配置することで、さらにミスト放出口３７ｅが食品等で塞がれるのを防止することができる。 Further, by arranging the bottom surface portion of the atomizing cover member 37 so as to be inclined upward toward the front opening of the refrigerating chamber 14, it is possible to further prevent the mist discharge port 37e from being blocked by food or the like.

また、霧化カバー部材３７の側面部３７ｄが庫内へ突出して形成され、ミスト放出口３７ｅが庫内空間内に突出して形成されているので、庫内の空気を霧化カバー部材３７内に取り込みやすい。 Further, since the side surface portion 37d of the atomizing cover member 37 is formed so as to project into the refrigerator and the mist discharge port 37e is formed to protrude into the interior space, the air in the refrigerator is formed into the atomizing cover member 37. Easy to capture.

したがって、庫内空気と一緒に、空気に含まれる水分を取り込む取組み口としてミスト放出口３７ｅは機能するので、霧化部３０で水が生成された時に霧化カバー部材３７内の空気中の水分が減少するが、このミスト放出口３７ｅが霧化カバー部材３７内に庫内空気取込み孔として機能し、継続的に庫内空気を送り込んで空気を入れ替えることができやすく、継続的に適度なミストを発生させることができ、ミスト中に含まれるＯＨラジカルが各種の臭い成分を分解して除菌および脱臭を高めることができる。 Therefore, since the mist discharge port 37e functions as an action port for taking in the moisture contained in the air together with the air inside the refrigerator, the moisture in the air in the atomization cover member 37 when water is generated by the atomization unit 30. However, this mist discharge port 37e functions as an air intake hole in the refrigerator in the atomization cover member 37, and it is easy to continuously send the air in the refrigerator to replace the air, and the mist is continuously appropriate. Can be generated, and the OH radical contained in the mist can decompose various odorous components to enhance sterilization and deodorization.

また霧化カバー部材３７の吹出し口２６ａに対向する側に形成された開口部３７ｇの開口面積は、吹出し口２６ａに対向しない側に形成された開口部３７ｈの開口面積よりも小さくなるように構成されており、吹出し口２６ａ近傍の低湿度の冷気が積極的に入らないようになっている。 Further, the opening area of the opening 37g formed on the side of the atomizing cover member 37 facing the outlet 26a is configured to be smaller than the opening area of the opening 37h formed on the side not facing the outlet 26a. The low humidity cold air in the vicinity of the outlet 26a is prevented from actively entering.

また実施例の場合、吹出し口２６ａは冷蔵室冷気風路２６の左右幅方向に２つ形成されており、霧化部３０は２つの吹出し口２６ａの延長線の間になるように吹出し口２６ａは左右両サイドに開口部が振られている。このため霧化部３０に吹出し口２６ａから吹出される低湿度の冷気が直接当たらないように構成されている。 Further, in the case of the embodiment, two outlets 26a are formed in the left-right width direction of the refrigerating chamber cold air passage 26, and the atomizing portion 30 is formed between the two outlets 26a so as to be between the extension lines of the two outlets 26a. Has openings on both the left and right sides. Therefore, the atomized portion 30 is configured so that the cold air of low humidity blown out from the outlet 26a does not directly hit the atomizing portion 30.

上記のように冷蔵室１４に配置された静電霧化装置２９について動作を説明する。 The operation of the electrostatic atomizer 29 arranged in the refrigerator compartment 14 as described above will be described.

図６のように、室内温度および相対湿度と露点温度の相関関係を示すテーブルを設け、冷蔵庫の冷蔵室１４の室内温度範囲（５±３℃）と冷蔵室１４の湿度範囲（３５％～９５％）の領域と、この領域における露点温度の最大値を湿り空気線図から求め露点温度とする。 図で、ペルチェ素子４２に１．０Ａの電流値を通電した場合で、図６の１.０Ａを示すペルチェ冷却能力線より上の範囲で結露するので、湿度が約３５％の低湿度で、室内温度が５～８℃では、霧化電極４０は結露領域にあり、素早くミストを噴霧することができる。 As shown in FIG. 6, a table showing the correlation between the indoor temperature and the relative humidity and the dew point temperature is provided, and the indoor temperature range (5 ± 3 ° C.) of the refrigerating chamber 14 of the refrigerator and the humidity range (35% to 95) of the refrigerating chamber 14 are provided. %) And the maximum value of the dew point temperature in this region is obtained from the psychrometric chart and used as the dew point temperature. In the figure, when a current value of 1.0 A is applied to the Pelche element 42, dew condensation occurs in the range above the Pelche cooling capacity line showing 1.0 A in FIG. 6, so that the humidity is as low as about 35%. When the room temperature is 5 to 8 ° C., the atomizing electrode 40 is in the condensation region and can quickly spray the mist.

しかし、室内温度が２～５℃の場合、約３５％の低湿度では、霧化電極４０は凍結領域となる。 However, when the room temperature is 2 to 5 ° C., the atomizing electrode 40 becomes a frozen region at a low humidity of about 35%.

この場合、凍結領域にある霧化電極４０を結露領域にするために、冷蔵室ダンパ３９を閉じて室温を５℃以上に上げる、または湿度を４０％以上に上昇させる制御を行うことで、素早くミストを噴霧することができる。 In this case, in order to make the atomizing electrode 40 in the frozen region into a dew condensation region, the refrigerating chamber damper 39 is closed and the room temperature is raised to 5 ° C. or higher, or the humidity is controlled to be raised to 40% or higher quickly. Mist can be sprayed.

したがって、１．０Ａでは図６の斜線部分の範囲で、ミストを素早く噴霧することができる。 Therefore, at 1.0 A, the mist can be quickly sprayed within the range of the shaded area in FIG.

また、霧化電極４０の結露が多すぎると、逆に素早く噴霧することができないため、上限を９５％としている。 Further, if the atomization electrode 40 has too much dew condensation, on the contrary, it cannot be sprayed quickly, so the upper limit is set to 95%.

また、ペルチェ素子４２に０．５Ａの電流値を通電した場合は、湿度が約５５％以上であれば室内温度範囲（５±３℃）で、霧化電極４０は結露領域にあり、素早くミストを噴霧することができる。 Further, when a current value of 0.5 A is applied to the Pelche element 42, if the humidity is about 55% or more, the atomization electrode 40 is in the dew condensation region within the room temperature range (5 ± 3 ° C.), and the mist is swift. Can be sprayed.

しかし、湿度が約５５％以下であれば、凍結領域となり、素早くミストを噴霧することができない。 However, if the humidity is about 55% or less, it becomes a frozen region and mist cannot be sprayed quickly.

また、ペルチェ素子４２に１．５Ａの電流値を通電した場合は、室内温度範囲（５±３℃）では、図６より露点が－１０℃以下の領域にあり、霧化電極４０は凍結領域となり、素早くミストを噴霧することができない。 Further, when a current value of 1.5 A is applied to the Pelche element 42, the dew point is in the region of −10 ° C. or lower as shown in FIG. 6 in the indoor temperature range (5 ± 3 ° C.), and the atomizing electrode 40 is in the frozen region. And it is not possible to spray mist quickly.

したがって、冷蔵室１４で約３５％の低湿度以上の条件で素早くミストを噴霧するには、ペルチェ素子４２に１．０Ａの電流値を通電すれば可能であり、約５５％の中湿度以上の条件で素早くミストを噴霧するには、ペルチェ素子４２に０．５Ａの電流値を通電すれば可能となる。 Therefore, in order to quickly spray the mist in the refrigerating chamber 14 under the condition of low humidity of about 35% or more, it is possible by energizing the Pelche element 42 with a current value of 1.0 A, and the humidity of about 55% or more is medium humidity or higher. In order to quickly spray the mist under the conditions, it is possible to apply a current value of 0.5 A to the Pelche element 42.

よって、ペルチェ素子４２に０．５Ａ～１．０Ａの通電電流値を設定してやれば、冷蔵室内でのミストの噴霧を素早く行うことができる。 Therefore, if the current-carrying current value of 0.5 A to 1.0 A is set in the Pelche element 42, the mist can be quickly sprayed in the refrigerating room.

図７は静電霧化装置２９の動作を行うタイムチャートであり、冷蔵庫１に設置した外気温センサ（図示しない）による検知温度が１５℃以上の場合の静電霧化装置２９の第１動作モードである。 FIG. 7 is a time chart for operating the electrostatic atomizer 29, and is a first operation of the electrostatic atomizer 29 when the detection temperature by the outside air temperature sensor (not shown) installed in the refrigerator 1 is 15 ° C. or higher. The mode.

動作モードは空気中の水分を霧化電極４０に付着させて水を生成する結露モード、そして生成した水を霧化させる霧化モードの順に動作させ冷蔵室１４にミストを噴霧し、各モードについて具体的に説明する。 The operation mode is a dew condensation mode in which moisture in the air is attached to the atomization electrode 40 to generate water, and an atomization mode in which the generated water is atomized, and mist is sprayed on the refrigerating chamber 14 for each mode. This will be described in detail.

図７より、圧縮機２５がＯＮ状態で運転中に冷蔵室ダンパ３９が開放されて冷蔵室冷気風路２６を通って吹出し口２６ａから冷蔵室１４に冷気を吹出している。 From FIG. 7, while the compressor 25 is in the ON state, the refrigerating chamber damper 39 is opened, and cold air is blown from the outlet 26a to the refrigerating chamber 14 through the refrigerating chamber cold air passage 26.

そしてある時点で、冷蔵室１４の室内温度センサ（図示しない）が所定温度になると冷蔵室ダンパ３９は開状態から閉状態になるように閉信号が入力される。 Then, at a certain point, when the indoor temperature sensor (not shown) of the refrigerating chamber 14 reaches a predetermined temperature, a closing signal is input so that the refrigerating chamber damper 39 changes from the open state to the closed state.

冷蔵室ダンパ３９が開から閉になったことを起点として、静電霧化装置２９のペルチェ素子４２へ通電を開始して、第１結露モードの動作を行う。第１結露モードでは、高電圧をＯＦＦにした状態で、所定時間ペルチェ素子４２へ通電して霧化電極４０を冷却する。この時、電流値は０．８Ａの電流をペルチェ素子４２に通電することで冷却能力を高め、冷蔵室１４内の空気中の水分を霧化電極４０に付着させる。 Starting from the opening and closing of the refrigerating chamber damper 39, energization of the Pelche element 42 of the electrostatic atomizer 29 is started, and the operation of the first dew condensation mode is performed. In the first dew condensation mode, the atomizing electrode 40 is cooled by energizing the Pelche element 42 for a predetermined time with the high voltage turned off. At this time, the cooling capacity is increased by energizing the Pelche element 42 with a current value of 0.8 A, and the moisture in the air in the refrigerating chamber 14 is adhered to the atomizing electrode 40.

第１結露モードでは、冷蔵室ダンパ３９を閉じた際に開始するので、吹出し口２６ａから冷却器２２で熱交換された低温で低湿度の冷気が吐出されず、冷蔵室１４内で循環し熱交換した比較的湿度の高い空気中の水分を、水分の減少を抑制しながら高電流を通電することで冷却能力を高めて霧化電極４０に継続的に付着させることができる。 In the first dew condensation mode, since it starts when the refrigerating chamber damper 39 is closed, the low-temperature and low-humidity cold air exchanged by the cooler 22 is not discharged from the outlet 26a, and the heat circulates in the refrigerating chamber 14 and heats. The exchanged moisture in the relatively humid air can be continuously adhered to the atomization electrode 40 by increasing the cooling capacity by energizing a high current while suppressing the decrease in moisture.

また第１結露モードの動作時間は、実施例の場合、１０分間継続される。この動作時間は変更可能で負荷条件によって変えてもよく、例えば冷蔵室１４内に収納物が多い場合、庫内は高湿度になり易いので所定時間を短くしても良い。 Further, in the case of the embodiment, the operation time of the first dew condensation mode is continued for 10 minutes. This operating time can be changed and may be changed depending on the load conditions. For example, when there are many stored items in the refrigerator compartment 14, the inside of the refrigerator tends to have high humidity, so that the predetermined time may be shortened.

第１結露モードが所定時間行われた後、次に第２結露モードの動作が開始する。第２結露モードの動作時間は実施例の場合、３０秒間継続される。第２結露モードではペルチェ素子４２への通電を所定時間停止することであり、仮に第１結露モードで霧化電極４０が微凍結したとしても、第２結露モードで通電を停止することで、霧化電極４０の冷やしすぎで０℃以下にならないようにすることで、霧化電極４０に水を生成することができる。また生成した水が乾燥しないように、冷蔵室ダンパ３９が閉じた状態で行う。 After the first dew condensation mode is performed for a predetermined time, the operation of the second dew condensation mode is then started. In the case of the embodiment, the operation time of the second dew condensation mode is continued for 30 seconds. In the second dew condensation mode, the energization of the Pelche element 42 is stopped for a predetermined time. Even if the atomizing electrode 40 is slightly frozen in the first dew condensation mode, the energization is stopped in the second dew condensation mode to fog. Water can be generated in the atomizing electrode 40 by preventing the temperature of the atomizing electrode 40 from becoming 0 ° C. or lower due to excessive cooling. Further, the refrigerating chamber damper 39 is closed so that the generated water does not dry.

第２結露モードが所定時間経過した後、次に霧化モードの動作が開始する。霧化モードの動作時間は実施例の場合、１５分間継続される。霧化モードでは霧化電極４０と対向電極４１との間に高電圧を印加するとともに、ペルチェ素子４２への通電も行う。この時、第１結露モード時と同じ電流値を通電することで、霧化を行いながら霧化電極４０を冷却して空気中の水分を結露させることができるのでミストを継続して噴霧することができる。 After the second dew condensation mode elapses for a predetermined time, the operation of the atomization mode is started next. The operating time of the atomization mode is continued for 15 minutes in the case of the embodiment. In the atomization mode, a high voltage is applied between the atomization electrode 40 and the counter electrode 41, and the Pelche element 42 is also energized. At this time, by energizing the same current value as in the first dew condensation mode, the atomization electrode 40 can be cooled while atomizing to cause dew condensation in the air, so that mist should be continuously sprayed. Can be done.

したがって、結露モードを第１結露モードと第２結露モードとに分けて設定し、第１結露モード時はペルチェ素子４２に０．８Ａの電流を通電して霧化電極４０を冷却し、第２結露モード時はペルチェ素子４２への通電を停止して霧化電極４０の冷却を停止し、霧化電極４０を冷やしすぎないようにすることで、霧化電極４０の凍結を防止して水の生成を行うことができ、霧化モード中に、継続して素早くナノサイズのマイナスイオンミストを冷蔵室１４へ噴霧することができる。 Therefore, the dew condensation mode is set separately for the first dew condensation mode and the second dew condensation mode, and in the first dew condensation mode, a current of 0.8 A is applied to the Pelche element 42 to cool the atomizing electrode 40, and the second dew condensation mode is cooled. In the dew condensation mode, the energization of the Pelche element 42 is stopped to stop the cooling of the atomizing electrode 40, and the atomizing electrode 40 is not cooled too much to prevent the atomizing electrode 40 from freezing and water. The formation can be carried out and the nano-sized negative ion mist can be continuously and quickly sprayed onto the refrigerating chamber 14 during the atomization mode.

また、霧化モード中にペルチェ素子４２へ通電しない場合、霧化部３０の放熱側の熱が吸熱側に熱移動し霧化電極４０の温度が上昇し、さらに低湿度の冷蔵室１４の環境下によって、融解モードで生成した水の蒸発が促進し、霧化電極４０に水を保持することができず、素早くミストを供給できないおそれがある。 Further, when the Pelche element 42 is not energized during the atomization mode, the heat on the heat dissipation side of the atomization unit 30 is transferred to the endothermic side, the temperature of the atomization electrode 40 rises, and the environment of the refrigerating chamber 14 with low humidity is further increased. Underneath, the evaporation of the water produced in the melting mode is promoted, the water cannot be retained in the atomizing electrode 40, and there is a possibility that the mist cannot be supplied quickly.

また図７のように、静電霧化装置２９の第１融解モード動作を開始し、次の第２融解モード動作と、最後の霧化モードの開始時までは冷蔵室ダンパ３９が閉じている状態で行う方が、冷蔵室１４内の空気から水分を集めやすく継続して素早くミストを発生することができるが、利用者の使用状況により途中で冷蔵室ダンパ３９が開放された場合でも、静電霧化装置２９の第１動作モードは中断することなく各モード運転を行う。 Further, as shown in FIG. 7, the first melting mode operation of the electrostatic atomizer 29 is started, and the refrigerating chamber damper 39 is closed until the next second melting mode operation and the start of the final atomization mode. It is easier to collect water from the air in the refrigerating chamber 14 and it is possible to continuously and quickly generate mist if it is performed in the state, but even if the refrigerating chamber damper 39 is opened in the middle depending on the usage situation of the user, it is still. The first operation mode of the atomizing device 29 operates in each mode without interruption.

また、冷蔵室ダンパ３９の開閉サイクルに連動して、毎サイクル時に第１動作モードを行ってもよいが、所定サイクル毎に第１動作モードを動作させても良い。実施例の場合、冷蔵室ダンパ３９開閉の２サイクル毎に第１動作モードの運転を行い、冷蔵室１４内にミストを噴霧し、冷蔵室１４内の除菌および脱臭を行っている。 Further, the first operation mode may be performed at each cycle in conjunction with the opening / closing cycle of the refrigerator compartment damper 39, but the first operation mode may be operated at each predetermined cycle. In the case of the embodiment, the operation of the first operation mode is performed every two cycles of opening and closing the refrigerating chamber damper 39, mist is sprayed into the refrigerating chamber 14, and the refrigerating chamber 14 is sterilized and deodorized.

また図８は静電霧化装置２９の動作を行うタイムチャートであり、冷蔵庫１に設置した外気温センサ（図示しない）による検知温度が１５℃以下の場合の静電霧化装置２９の第２動作モードである。 Further, FIG. 8 is a time chart for operating the electrostatic atomizer 29, and is a second electrostatic atomizer 29 when the temperature detected by the outside air temperature sensor (not shown) installed in the refrigerator 1 is 15 ° C. or less. The operation mode.

図８より、外気温度が１５℃以下の低外気温時では、圧縮機２５の運転率が低く、低負荷のため冷蔵室ダンパ３９の開度率も低下し、圧縮機２５の運転がＯＮ状態であっても冷蔵室ダンパ３９が開放されず閉状態を継続し、冷蔵室ダンパ３９の開閉動作が圧縮機２５の運転サイクルに連動しない場合がある。 From FIG. 8, when the outside air temperature is low at 15 ° C. or lower, the operating rate of the compressor 25 is low, the opening rate of the refrigerator damper 39 also decreases due to the low load, and the operation of the compressor 25 is in the ON state. Even so, the refrigerating chamber damper 39 may not be opened and may continue to be closed, and the opening / closing operation of the refrigerating chamber damper 39 may not be linked to the operation cycle of the compressor 25.

このため、低外気温時は、冷蔵室ダンパ３９の開閉動作に関係なく、圧縮機２５がオフからオンになったことを起点として、静電霧化装置２９のペルチェ素子４２へ通電を開始して、第１融解モードを行う。第１融解モードではペルチェ素子４２へ通電して霧化電極４０を冷却する。この時、電流値０．８Ａの電流をペルチェ素子４２に通電することで冷却能力を高め、冷蔵室１４内の空気中の水分を霧化電極４０に付着させる。 Therefore, when the outside temperature is low, energization is started to the Pelche element 42 of the electrostatic atomizer 29 from the turning point of the compressor 25 from the off to the on, regardless of the opening / closing operation of the refrigerating chamber damper 39. Then, the first melting mode is performed. In the first melting mode, the Pelche element 42 is energized to cool the atomizing electrode 40. At this time, the cooling capacity is increased by energizing the Pelche element 42 with a current having a current value of 0.8 A, and the moisture in the air in the refrigerating chamber 14 is adhered to the atomizing electrode 40.

第１融解モードでは、冷蔵室ダンパ３９の開度率が低下し、閉じた状態が継続する場合が多く、冷蔵室１４内で循環し熱交換した空気のため、ペルチェ素子４２に高電流を通電して冷却能力を高めて、比較的高湿度の空気中の水分を霧化電極４０に付着させることができる。これによって冷蔵室１４内の水分の減少を抑制しながら継続的に水分を付着させることができる。 In the first melting mode, the opening rate of the refrigerating chamber damper 39 decreases and the closed state often continues, and the air circulating in the refrigerating chamber 14 and exchanging heat energizes the Pelche element 42 with a high current. Therefore, the cooling capacity can be increased, and the moisture in the air having a relatively high humidity can be attached to the atomizing electrode 40. As a result, it is possible to continuously attach water while suppressing the decrease in water in the refrigerating chamber 14.

また第１融解モードは第１動作モード時と同様に、所定時間継続運転され、所定時間は変更可能としてもよい。 Further, the first melting mode may be continuously operated for a predetermined time as in the first operation mode, and the predetermined time may be changeable.

また第１融解モードが所定時間行われた後、第２融解モードは、第１動作モードと同様に、ペルチェ素子４２への通電を所定時間停止することであり、霧化電極４０を冷やしすぎ０℃以下にならないようにすることで、霧化電極４０に水を生成する。 Further, after the first melting mode is performed for a predetermined time, the second melting mode is to stop the energization of the Pelche element 42 for a predetermined time as in the first operation mode, and the atomizing electrode 40 is overcooled to 0. Water is generated in the atomizing electrode 40 by keeping the temperature below ° C.

また霧化モードは、第１動作モード時と同様に所定時間継続運転される。また使用条件により、第２動作モードの途中で圧縮機２５がオフ、または冷蔵室ダンパ３９が開放された場合でも、静電霧化装置２９の第２動作モードは中断することなく各モードで運転を行う。 Further, the atomization mode is continuously operated for a predetermined time as in the first operation mode. Further, depending on the usage conditions, even if the compressor 25 is turned off or the refrigerating chamber damper 39 is opened in the middle of the second operation mode, the second operation mode of the electrostatic atomizer 29 is operated in each mode without interruption. I do.

また、圧縮機２５のオフ／オン動作に連動して、毎サイクル時に第２動作モードを行ってもよいが、所定サイクル毎に第２動作モードを動作させても良い。図７では圧縮機２５の運転の２サイクル毎に第２動作モードの運転を行い、冷蔵室１４内にミストを噴霧し、冷蔵室１４内の除菌および脱臭を行っている。 Further, the second operation mode may be performed at each cycle in conjunction with the off / on operation of the compressor 25, but the second operation mode may be operated at each predetermined cycle. In FIG. 7, the operation of the second operation mode is performed every two cycles of the operation of the compressor 25, mist is sprayed into the refrigerating chamber 14, and the refrigerating chamber 14 is sterilized and deodorized.

また、冷蔵室１４内に室内の湿度を検知する湿度検知手段４５を備えており、湿度検知手段４５が所定の湿度以上を検知した場合は、第１融解モード時のペルチェ素子４２への通電時間を減算して所定時間よりも短くし、霧化電極４０に空気中の水分が付着しすぎたり、融解した時に霧化電極４０から水滴となって落下するのを抑制することができる。 Further, the refrigerating chamber 14 is provided with a humidity detecting means 45 for detecting the humidity in the room, and when the humidity detecting means 45 detects a predetermined humidity or more, the energization time to the Pelche element 42 in the first melting mode is provided. Is made shorter than a predetermined time by subtracting the above, and it is possible to prevent the moisture in the air from adhering too much to the atomizing electrode 40 or falling from the atomizing electrode 40 as water droplets when it melts.

またさらに湿度検知手段４５による検知湿度が高湿度の場合、第１融解モードを停止し、霧化モードのみを実行する。したがって素早くミストを室内に供給することができる。 Further, when the humidity detected by the humidity detecting means 45 is high humidity, the first melting mode is stopped and only the atomization mode is executed. Therefore, the mist can be quickly supplied to the room.

また湿度検知手段４５を冷蔵室１４内に設置したが、本体２の庫外側に設置し、外気湿度に応じて、第１融解モードの動作時間の減算または停止を行ってもよい。 Further, although the humidity detecting means 45 is installed in the refrigerating chamber 14, it may be installed outside the refrigerator of the main body 2 to subtract or stop the operating time of the first melting mode according to the outside air humidity.

また、図５の霧化カバー部材３７内の霧化部湿度センサ４６を備えることで、霧化電極４０近傍の検知湿度と、冷蔵室戻り風路（図示しない）に備えた冷蔵室温度センサ４７による検知温度とに基づいて、図６のテーブルにより、ペルチェ素子４２への通電電流値を可変可能に設定することができ、冷蔵室１４へのミスト噴霧を効率的に素早く行うことができる。 Further, by providing the atomizing portion humidity sensor 46 in the atomizing cover member 37 of FIG. 5, the detected humidity in the vicinity of the atomizing electrode 40 and the refrigerating chamber temperature sensor 47 provided in the refrigerating chamber return air passage (not shown). The current value to the Pelche element 42 can be variably set based on the detection temperature according to the above, and the mist spray to the refrigerating chamber 14 can be efficiently and quickly performed.

また、冷蔵室扉９の開閉を検知するドアスイッチ４８を有し、ドアスイッチ４８が冷蔵室扉９が閉じたことを検知した時に、ペルチェ素子４２への通電を行うので、冷蔵室扉９を開放した時に外気湿度が庫内に入るので空気中の水分を霧化電極４０に集めやすくなり、素早くミストを噴霧することができる。 Further, it has a door switch 48 for detecting the opening / closing of the refrigerating room door 9, and when the door switch 48 detects that the refrigerating room door 9 is closed, the Pelche element 42 is energized. Since the outside air humidity enters the refrigerator when the door is opened, the moisture in the air can be easily collected on the atomizing electrode 40, and the mist can be sprayed quickly.

また図５の霧化カバー部材３７内で霧化電極４０に対向する位置にアルミ板５０を備えている。 Further, an aluminum plate 50 is provided at a position facing the atomization electrode 40 in the atomization cover member 37 of FIG.

したがって、アルミ板５０が冷却されて表面を結露させることで、霧化電極４０周辺の湿度を高めることができ、素早くミストを噴霧させることが可能になる。 Therefore, when the aluminum plate 50 is cooled to cause dew condensation on the surface, the humidity around the atomizing electrode 40 can be increased, and the mist can be sprayed quickly.

アルミ板５０としたが、他の金属性の板でもよく、結露発生手段となる部材を霧化電極４０に対向配置することで、周囲の湿度を上げて霧化電極４０に水が付着しやすくしなり、ミストの噴霧を促進することができる。 Although the aluminum plate 50 is used, other metallic plates may be used, and by arranging a member serving as a dew condensation generating means facing the atomizing electrode 40, the surrounding humidity is increased and water easily adheres to the atomizing electrode 40. It can bend and promote mist spraying.

また第１融解モード時に冷蔵室扉９が開放されても、ペルチェ素子４２への通電を継続し第１融解モード動作は運転を続ける。冷蔵室扉９の開放によって外気湿度が庫内に入るので空気中の水分を霧化電極４０に集めやすくなる。 Even if the refrigerating chamber door 9 is opened in the first melting mode, the Pelche element 42 is continuously energized and the first melting mode operation continues to operate. By opening the refrigerator door 9, the outside air humidity enters the refrigerator, so that it becomes easier to collect the moisture in the air to the atomizing electrode 40.

また霧化モード時に冷蔵室扉９が開放されると、霧化モード動作を停止、すなわちペルチェ素子４２への通電および高電圧の印加を停止する、そして冷蔵室扉９が閉じられると、霧化モード動作を再度開始し、残時間分の運転を行ってミストを冷蔵室１４へ噴霧し、室内の除菌や脱臭を高めることができる。 Further, when the refrigerating chamber door 9 is opened in the atomization mode, the atomization mode operation is stopped, that is, energization and application of a high voltage to the Pelche element 42 are stopped, and when the refrigerating chamber door 9 is closed, atomization is performed. The mode operation is restarted, the operation for the remaining time is performed, and the mist is sprayed onto the refrigerating chamber 14, so that the disinfection and deodorization of the chamber can be enhanced.

本開示は、霧化モード時も霧化電極を冷却するので、霧化電極への水の供給を継続して行うことができ、素早くミストを室内に供給することができる冷蔵庫に適用可能である。 The present disclosure is applicable to a refrigerator in which the atomizing electrode is cooled even in the atomization mode, so that water can be continuously supplied to the atomizing electrode and mist can be quickly supplied to the room. ..
