Description

本発明は、冷蔵庫に関する。   The present invention relates to a refrigerator.

特許文献1(特開2006−105420号公報)には、冷凍温度室において製氷皿を電動機構によって回動させることによりこの製氷皿内の氷を下方へ落下させる自動製氷機であって、電動機構が後部に配置されその前方位置に製氷皿が配置された本体部材が冷凍温度室の上部に着脱自在に取り付けられ、本体部材には、冷凍温度室の後部から吹き出す冷気を製氷皿へ供給する冷気供給通路を電動機構の側方を通って製氷皿の側方に向けて屈曲配置したことが記載されている。   Japanese Patent Application Laid-Open No. 2006-105420 discloses an automatic ice maker that causes ice in the ice tray to fall downward by rotating the ice tray by an electric mechanism in a freezing temperature chamber. A main body member having an ice tray arranged at the rear and an ice tray at a front position thereof is detachably attached to the upper portion of the freezing temperature chamber, and the main body member is supplied with cold air that blows from the rear of the freezing temperature chamber to the ice making tray. It is described that the supply passage is bent toward the side of the ice tray through the side of the electric mechanism.

特開2006−105420号公報JP 2006-105420 A

特許文献1のように、一般的な冷蔵庫は、冷凍温度帯室後方の冷却器室に冷却器が配置されて、冷凍温度帯室に冷気を循環する送風機は冷却器室内、すなわち、冷凍温度帯室の後方中央に設けられている。一方、自動製氷機は、冷凍温度帯室の冷蔵庫本体に対して右寄り又は左寄りに設けられる。   As in Patent Document 1, in a general refrigerator, a cooler is disposed in a cooler room behind a freezing temperature zone, and a blower that circulates cold air to the freezing temperature zone is a cooler room, that is, a freezing temperature zone. It is provided in the rear center of the chamber. On the other hand, the automatic ice making machine is provided on the right side or the left side with respect to the refrigerator main body in the freezing temperature zone.

この構成において、製氷皿への冷気供給通路は、冷蔵庫本体中央よりの製氷皿側方から、製氷皿表面に冷気を導く。すなわち、送風機から製氷皿までの冷気供給通路の距離をなるべく短くするために、送風機に近い側の製氷皿の側方から冷気を供給している。   In this configuration, the cold air supply passage to the ice tray guides cold air from the side of the ice tray to the ice tray surface from the center of the refrigerator body. That is, in order to shorten the distance of the cold air supply passage from the blower to the ice tray, the cold air is supplied from the side of the ice tray near the blower.

仮に冷気通路を冷蔵庫本体の側壁側(送風機に遠い側の製氷皿の側方)とする場合、送風機からの距離が長くなり、風路抵抗が増加する。   If the cold air passage is on the side wall side of the refrigerator main body (the side of the ice tray on the side far from the blower), the distance from the blower becomes longer and the air path resistance increases.

特許文献1記載の構成では、製氷皿を冷やすために設けた製氷皿収納室側面の通気孔が、検氷レバーに対向する位置にあるため、製氷皿表面に効率よく冷気を供給して冷却することができない。   In the configuration described in Patent Document 1, the air vent on the side of the ice tray storage chamber provided for cooling the ice tray is located at a position facing the ice detecting lever, so that cool air is efficiently supplied to the ice tray surface for cooling. I can't.

また、検氷レバーに霜が付着することで、正確な検氷ができなくなるおそれがある。   Moreover, there is a possibility that accurate ice detection cannot be performed because frost adheres to the ice detection lever.

そこで本発明は、製氷効率を向上して、かつ貯氷量の検知精度を向上した冷蔵庫を提供することを目的とする。   Therefore, an object of the present invention is to provide a refrigerator with improved ice making efficiency and improved accuracy of detecting the amount of ice stored.

本発明では、上述の課題を解決するため、例えば特許請求の範囲に記載の手段を採用する。一例として、貯氷量を検知する検氷レバーと、該検氷レバーで貯氷量不足を検知した場合に製氷皿を回転駆動して離氷する電動機構部と、を有する自動製氷機を備えた冷蔵庫において、前記自動製氷機は製氷フレームを備え、該製氷フレームは、前記製氷皿を収納する製氷皿収納室と、前記製氷皿収納室と区画されて前記検氷レバーを収納する検氷レバー収納室と、が形成されて、前記製氷皿収納室の側部から冷気を導く第一の冷気通路と、前記検氷レバー収納室に冷気を導く第三の冷気通路と、前記製氷皿収納室の上部及び前記第三の冷気通路に冷気を導く第二の冷気通路と、を備え、前記検氷レバー収納室の壁に検氷レバー収納室開口が形成されて、前記第三の冷気通路から前記検氷レバー収納室開口を通過した冷気が前記検氷レバー収納室に導かれる
In the present invention, in order to solve the above-described problems, for example, means described in the claims are adopted. As an example, a refrigerator equipped with an automatic ice maker having an ice detection lever for detecting the amount of ice stored, and an electric mechanism for rotating the ice making tray to release the ice when the ice detection lever detects that the ice storage amount is insufficient The automatic ice making machine includes an ice making frame, and the ice making frame is divided into an ice making tray storage chamber for storing the ice tray, and an ice detection lever storage chamber for storing the ice detection lever which is partitioned from the ice tray storage chamber. And a first cold air passage that guides cold air from a side of the ice tray storage chamber, a third cold air passage that guides cold air to the ice detection lever storage chamber, and an upper portion of the ice tray storage chamber And an ice detection lever storage chamber opening formed in a wall of the ice detection lever storage chamber, and the detection from the third cold air passage. The cold air that has passed through the ice lever storage chamber opening collects the ice detection lever. It is led into the chamber.

本発明によれば、製氷効率を向上して、かつ貯氷量の検知精度を向上した冷蔵庫を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the ice-making efficiency can be improved and the refrigerator which improved the detection accuracy of ice storage amount can be provided.

まず、冷蔵庫の全体構成について説明する。図1、図2、図3において、1は冷蔵庫本体である。冷蔵庫本体1は、外箱2と内箱3との間に断熱材4(例えば発泡断熱材、真空断熱材等)を備えた断熱箱体によって、内部と外部が区画される。冷蔵庫本体1の下部後方には、冷凍サイクルの一部である圧縮機5が配置される。なお、圧縮機5は、貯蔵室と断熱的に区画されていれば、冷蔵庫本体1の上部後方等であってもよく、その設置位置は特に限定されるものではない。   First, the whole structure of a refrigerator is demonstrated. 1, 2, and 3, reference numeral 1 denotes a refrigerator body. The refrigerator main body 1 is divided into an inside and an outside by a heat insulating box body provided with a heat insulating material 4 (for example, a foam heat insulating material, a vacuum heat insulating material, etc.) between the outer box 2 and the inner box 3. A compressor 5 that is a part of the refrigeration cycle is disposed at the lower rear of the refrigerator body 1. As long as the compressor 5 is partitioned from the storage room in an adiabatic manner, the compressor 5 may be located behind the upper portion of the refrigerator body 1 and the installation position thereof is not particularly limited.

冷蔵庫本体1内には冷蔵室6、製氷室14、上段冷凍室7a、下段冷凍室7、野菜室8の貯蔵室が形成されている。冷凍サイクルは圧縮機5、凝縮器、キャピラリチュ−ブ、冷却器18等より構成されるもので、圧縮機5で圧縮された冷媒は凝縮器(図示せず)で凝縮され、キャピラリチュ−ブなどの減圧部を通って蒸発器(後述する冷却器)で蒸発し、再び圧縮機5に帰還して圧縮されるように循環し、これを繰り返す。これにより、先の冷蔵室6、下段冷凍室7、野菜室8内を、所定温度まで冷却する。   In the refrigerator main body 1, a storage room for a refrigerator compartment 6, an ice making compartment 14, an upper freezer compartment 7 a, a lower freezer compartment 7, and a vegetable compartment 8 is formed. The refrigeration cycle is composed of a compressor 5, a condenser, a capillary tube, a cooler 18, and the like. The refrigerant compressed by the compressor 5 is condensed by a condenser (not shown), and the capillary tube. It evaporates with an evaporator (cooler which will be described later) through a decompression section such as, circulates back to the compressor 5 so as to be compressed, and this is repeated. Thereby, the inside of the previous refrigerator compartment 6, the lower freezer compartment 7, and the vegetable compartment 8 is cooled to predetermined temperature.

冷蔵庫本体1の前方開口には冷蔵室6を開閉する冷蔵室扉9、製氷室14を開閉する製氷室扉、上段冷凍室を開閉する第一の冷凍室扉11、下段冷凍室7を開閉する第二の冷凍室扉12、野菜室8を開閉する野菜室扉13をそれぞれ備えている。   A refrigerator compartment door 9 that opens and closes the refrigerator compartment 6, an ice making compartment door that opens and closes the ice compartment 14, a first freezer compartment door 11 that opens and closes the upper freezer compartment, and a lower freezer compartment 7 are opened and closed at the front opening of the refrigerator body 1. A second freezer compartment door 12 and a vegetable compartment door 13 for opening and closing the vegetable compartment 8 are provided.

また、冷蔵室扉9は、図1に示すヒンジ15等で回転可能に冷蔵庫本体1に接続された、観音開き式(フレンチドア)である。その他の扉は、引き出し式であり、扉を引き出すと各貯蔵室内の収納容器が扉枠及びレ−ル等によって扉と共に引き出されるように構成されている。   Moreover, the refrigerator compartment door 9 is a double door type (French door) connected to the refrigerator main body 1 so that rotation is possible by the hinge 15 etc. which are shown in FIG. The other doors are of a drawer type, and are configured such that when the door is pulled out, the storage container in each storage chamber is pulled out together with the door by a door frame and a rail.

16は冷却器室である。冷却器室16は、下段冷凍室7の後方に仕切部材17で区画して構成されている。冷却器室16には、冷凍サイクルの一部を構成している冷却器18が配置されている。19は冷却器18の下方に配置されて冷却器18に付いた霜を除去する除霜ヒータであり、20は冷気循環手段の送風機である。送風機19は、冷却器18で熱交換した冷気を冷蔵室6、製氷室14、上段冷凍室7a、下段冷凍室7、野菜室8に循環する。21はダンパーであり、送風機20から各貯蔵室に送風する冷気量を制御し、各貯蔵室を予め設定した温度に制御する役目を果たす。   Reference numeral 16 denotes a cooler chamber. The cooler chamber 16 is configured to be partitioned by a partition member 17 behind the lower freezing chamber 7. A cooler 18 constituting a part of the refrigeration cycle is disposed in the cooler chamber 16. A defrost heater 19 is disposed below the cooler 18 to remove frost attached to the cooler 18, and a blower 20 serves as a cool air circulation means. The blower 19 circulates the cold air exchanged by the cooler 18 to the refrigerator compartment 6, the ice making compartment 14, the upper freezer compartment 7 a, the lower freezer compartment 7, and the vegetable compartment 8. Reference numeral 21 denotes a damper that controls the amount of cool air blown from the blower 20 to each storage room and serves to control each storage room to a preset temperature.

22は冷蔵室6と冷凍温度帯室(製氷室14、上段冷凍室7a、下段冷凍室7)とを区画する断熱仕切壁であり、23は冷凍温度帯室と野菜室8とを区画する断熱仕切壁である。すなわち、温度帯が異なる冷蔵温度帯室と冷凍温度帯室の間は、断熱仕切壁22、23によって断熱的に区画されて、温度帯が共通の冷凍温度帯室(製氷室14、上段冷凍室7a、下段冷凍室7)は、各扉のシール部材を受けるように前方が区画されていて、後方は冷気の往来が可能な構成である。   22 is a heat insulating partition wall that partitions the refrigerator compartment 6 and the freezing temperature zone chamber (the ice making chamber 14, the upper freezing chamber 7a, the lower freezing chamber 7), and 23 is a heat insulation partitioning the freezing temperature zone chamber and the vegetable compartment 8. It is a partition wall. That is, the refrigeration temperature zone chamber and the refrigeration temperature zone chamber having different temperature zones are adiabatically partitioned by the heat insulating partition walls 22 and 23, and the temperature zone has a common refrigeration temperature zone chamber (ice making chamber 14, upper freezer compartment). 7a, the lower freezer compartment 7) is configured such that the front is partitioned so as to receive the seal member of each door, and cool air can flow back and forth.

24は冷蔵室6内に設けられた貯水タンクである。貯水タンク24内の水は、ポンプ等の給水手段によって、後述する自動製氷機の製氷皿に給水される。   Reference numeral 24 denotes a water storage tank provided in the refrigerator compartment 6. The water in the water storage tank 24 is supplied to an ice tray of an automatic ice maker described later by water supply means such as a pump.

25は自動製氷機である。自動製氷機25とは、製氷フレーム29内に電動機構部26と、電動機構部26によって回動駆動される製氷皿27、後述する貯氷容器30内の氷の量を検出する検氷レバー28等が組み込まれたものである。   Reference numeral 25 denotes an automatic ice making machine. The automatic ice making machine 25 includes an electric mechanism unit 26 in an ice making frame 29, an ice tray 27 that is rotationally driven by the electric mechanism unit 26, an ice detecting lever 28 that detects the amount of ice in an ice storage container 30 described later, and the like. Is incorporated.

なお、製氷皿27は樹脂製であり、ひねり可能な材質で構成された前後方向に長い形態をなし、長手方向を列方向として4個2列、5個2列、または6個2列のように複数のセルに区分されている。   The ice tray 27 is made of resin and has a long shape in the front-rear direction made of a material that can be twisted, and has four rows, two rows, five rows, or six rows in the longitudinal direction. Are divided into a plurality of cells.

また、検氷レバー28は図2に示すごとく幅広でL字形状をなすもので、先の電動機構部26の駆動力で支点28aを中心に先端が矢印a方向に移動し貯氷タンク24内の氷の量を検出する。   The ice detecting lever 28 is wide and has an L shape as shown in FIG. 2, and the tip of the ice detecting lever 28 moves in the direction of the arrow a around the fulcrum 28a by the driving force of the electric mechanism 26. Detect the amount of ice.

自動製氷機25は、後述する如く冷蔵庫本体1の左側(送風機20から遠い方)に検氷レバー28を、冷蔵庫本体1の右側に製氷皿27冷却用の冷気通路(後述する第一の冷気通路33)を設けた構成をとっている。貯氷容器30は、製氷室扉10側の扉枠10aに懸架されており、製氷室扉10を手前側に引き出すと、製氷室扉10とともに引き出される構成となっている。   As will be described later, the automatic ice making machine 25 has an ice detecting lever 28 on the left side (away from the blower 20) of the refrigerator main body 1 and a cold air passage for cooling the ice tray 27 on the right side of the refrigerator main body 1 (first cold air passage to be described later). 33) is provided. The ice storage container 30 is suspended from the door frame 10 a on the ice making room door 10 side, and is configured to be pulled out together with the ice making room door 10 when the ice making room door 10 is pulled out to the near side.

自動製氷機25の外郭を構成する製氷フレーム29は、図2、図3に示す如く製氷室14に仕切部材17と関連して取り付けられている。すなわち、仕切部材17は図4に示す第一の冷気吹き出し口31、第二の冷気吹き出し口32より吹き出される冷気を、製氷フレーム29内に取り込むように配置されている。   The ice making frame 29 constituting the outer shell of the automatic ice making machine 25 is attached to the ice making chamber 14 in association with the partition member 17 as shown in FIGS. That is, the partition member 17 is arranged so as to take in the cold air blown out from the first cold air outlet 31 and the second cold air outlet 32 shown in FIG.

そして、製氷フレーム29は第一の冷気通路33、第二の冷気通路34、第三の冷気通路35を有し、製氷皿27、及び検氷レバー28の冷却並びに霜付きの防止を行う。   The ice making frame 29 has a first cold air passage 33, a second cold air passage 34, and a third cold air passage 35, and cools the ice tray 27 and the ice detecting lever 28 and prevents frost formation.

具体的に、図4に示すように、第一の冷気吹き出し口31と第二の冷気吹き出し口32は、左右に並んで仕切部材17に配置されている。冷蔵庫本体1の左右方向の中央寄りに配置された第一の冷気吹き出し口31より吹き出された冷気は、第一の冷気通路33(図5参照)に導かれる。第二の冷気吹き出し口32より吹き出された冷気は、第二の冷気通路34、第三の冷気通路35(図3、図5参照)に導かれる。   Specifically, as shown in FIG. 4, the first cold air outlet 31 and the second cold air outlet 32 are arranged on the partition member 17 side by side. The cold air blown out from the first cold air outlet 31 disposed near the center in the left-right direction of the refrigerator body 1 is guided to the first cold air passage 33 (see FIG. 5). The cold air blown out from the second cold air outlet 32 is guided to the second cold air passage 34 and the third cold air passage 35 (see FIGS. 3 and 5).

なお、自動製氷機25の製氷制御、冷蔵室6、下段冷凍室7、野菜室8等の温度制御、その他冷蔵庫の諸機能は、冷蔵庫本体1に備えた制御機器によって制御される。   The ice making control of the automatic ice making machine 25, the temperature control of the refrigerator compartment 6, the lower freezer compartment 7, the vegetable compartment 8, etc., and other various functions of the refrigerator are controlled by control devices provided in the refrigerator main body 1.

次に、冷気通路についてさらに詳細に説明する。図4に示す第二の冷気吹き出し口32により吹き出された冷気は、製氷フレーム29と製氷室14の上壁14aとの間に形成される第二の冷気通路34(図3、図5参照)を通って、第三の冷気通路35に導入され、検氷レバー収納室36を形成する検氷レバー収納室側壁29dに設けられた検氷レバー収納室開口37を介して検氷レバー収納室36(図8参照)に吹き出される。これにより、検氷レバー28に付く霜を冷気で昇華させ、検氷レバー28が霜付きで誤検出するのを防止する。   Next, the cold air passage will be described in more detail. The cold air blown out by the second cold air outlet 32 shown in FIG. 4 is a second cold air passage 34 formed between the ice making frame 29 and the upper wall 14a of the ice making chamber 14 (see FIGS. 3 and 5). The ice detection lever storage chamber 36 is introduced into the third cold air passage 35 through an ice detection lever storage chamber opening 37 provided on the side wall 29d of the ice detection lever storage chamber forming the ice detection lever storage chamber 36. (See FIG. 8). Thereby, the frost attached to the ice detecting lever 28 is sublimated with cold air, and the ice detecting lever 28 is prevented from being erroneously detected due to frost.

すなわち、検氷レバー28は図2に示すように、離氷前に矢印a方向に移動し、貯氷容器30内の氷の量を検出し、製氷皿27で完成した氷を貯氷容器30内に落下させるか否かを判定する。ここで、検氷レバー28に霜が成長すると、氷の検知高さが変わり、正確な氷の量が測定できなくなってしまう。そこで、第三の冷気通路35を構成し、検氷レバー28に冷気を当てて、例えば製氷室扉13開閉時に検氷レバー28に付いた霜を昇華させるようにした。   That is, as shown in FIG. 2, the ice detecting lever 28 moves in the direction of arrow a before deicing, detects the amount of ice in the ice storage container 30, and completes the ice in the ice tray 27 into the ice storage container 30. Determine whether to drop. Here, when frost grows on the ice detecting lever 28, the detected height of the ice changes, and the accurate amount of ice cannot be measured. Therefore, the third cold air passage 35 is formed, and cold air is applied to the ice detecting lever 28 so that, for example, frost attached to the ice detecting lever 28 is sublimated when the ice making chamber door 13 is opened and closed.

電動機構部26は、製氷皿27の後方、且つ仕切部材17の前方に位置する。第一の冷気通路33からの冷気は、電動機構部26によって流れが阻害されないように考慮する必要がある。そこで、図3に示すように、第一の冷気吹き出し口31より吹き出された冷気は、製氷フレーム29(電動機構部26の上面)と製氷室14の上壁14aとの間の第二の冷気通路34を経て、製氷フレーム29上面に形成された通気孔29bより製氷皿収納室39内にある製氷皿27上面に流入する。   The electric mechanism unit 26 is located behind the ice tray 27 and in front of the partition member 17. It is necessary to consider the cold air from the first cold air passage 33 so that the electric mechanism portion 26 does not hinder the flow. Therefore, as shown in FIG. 3, the cold air blown out from the first cold air outlet 31 is the second cold air between the ice making frame 29 (the upper surface of the electric mechanism section 26) and the upper wall 14a of the ice making chamber 14. After passing through the passage 34, the air flows into the upper surface of the ice tray 27 in the ice tray storage chamber 39 from the air holes 29 b formed in the upper surface of the ice frame 29.

第一の冷気通路33、第三の冷気通路35は、製氷フレーム29側に設けた風路である。そのため、製氷皿27の前方(電動機構部26とは製氷皿27を隔てた反対側)まで至っている。一方、第二の冷気通路34は、通気孔29bの上方まで、すなわち、製氷皿27の長手方向で見た場合、電動機構部26よりである。   The first cold air passage 33 and the third cold air passage 35 are air passages provided on the ice making frame 29 side. Therefore, it reaches the front of the ice tray 27 (the side opposite to the electric mechanism portion 26 with the ice tray 27). On the other hand, the second cold air passage 34 is located above the ventilation hole 29 b, that is, from the electric mechanism portion 26 when viewed in the longitudinal direction of the ice tray 27.

次に図5〜図10において電動機構部26、製氷皿27等を収納した製氷フレーム29について説明する。   Next, the ice making frame 29 that houses the electric mechanism 26, the ice tray 27, etc. will be described with reference to FIGS.

図5において、44は第二の冷気通路の風向板である。第二の冷気通路の風向板44は、第二の冷気通路34の上流側に設けられており、通気孔29b側に流れて製氷皿収納室39に導かれる冷気と、第三の冷気通路35から検氷レバー収納室36に導かれる冷気とを振り分ける働きを備えている。なお、冷気量は、検氷レバー収納室36よりも製氷皿収納室39が多くなるように分配する。   In FIG. 5, reference numeral 44 denotes a wind direction plate of the second cold air passage. The wind direction plate 44 of the second cold air passage is provided on the upstream side of the second cold air passage 34, the cold air flowing to the air vent 29 b side and guided to the ice tray storage chamber 39, and the third cold air passage 35. To the cold air led to the ice detecting lever storage chamber 36. The amount of cold air is distributed so that the ice tray storage chamber 39 is larger than the ice detecting lever storage chamber 36.

ここで、製氷フレーム29の全体構成について説明する。製氷フレーム29は、樹脂を射出成形して一体に形成している。この製氷フレーム29は、図5〜図10に示すように、下面が開放する門型形状であり、送風機20に近い側に配置される第一の冷気通路33と、送風機20から遠い側に配置される検氷レバー収納室36と、第一の冷気通路33と検氷レバー収納室36との間に配置される製氷皿収納室39とを備える。製氷皿収納室39の後方には、電動機構部26を配置する電動機構部収納室40を有し、製氷皿収納室39の前方には、製氷皿27の引き出し口41を形成している。   Here, the overall configuration of the ice making frame 29 will be described. The ice making frame 29 is integrally formed by injection molding of resin. As shown in FIGS. 5 to 10, the ice making frame 29 has a gate-like shape with an open lower surface, and is disposed on the first cold air passage 33 disposed on the side close to the blower 20 and on the side far from the blower 20. The ice detection lever storage chamber 36 and an ice making tray storage chamber 39 disposed between the first cold air passage 33 and the ice detection lever storage chamber 36 are provided. At the rear of the ice tray storage chamber 39, there is an electric mechanism section storage chamber 40 in which the electric mechanism section 26 is arranged, and at the front of the ice tray storage chamber 39, a drawer port 41 for the ice tray 27 is formed.

製氷皿27は、枠42(図10参照)及び製氷フレーム29側に設けたレ−ル38によって、製氷皿収納室39内を前後に摺動する。そして、製氷皿27を製氷皿収納室39に収納した状態では、電動機構部26の駆動軸26aと連結し、製氷皿27を引き出した状態では、駆動軸26aとの連結関係が解除される。   The ice tray 27 slides back and forth in the ice tray storage chamber 39 by a frame 42 (see FIG. 10) and a rail 38 provided on the ice making frame 29 side. When the ice tray 27 is stored in the ice tray storage chamber 39, the ice tray 27 is connected to the drive shaft 26a of the electric mechanism 26, and when the ice tray 27 is pulled out, the connection relationship with the drive shaft 26a is released.

更に、第一の冷気通路33、第二の冷気通路34、第三の冷気通路35は、製氷フレーム29を製氷室14の上壁14aに取り付けた場合、上壁14aと製氷フレーム29との間に形成される。そして、第一の冷気吹き出し口31から吹き出された冷気は、第一の冷気通路33に流れ、第一の冷気通路33内に設けられた第一の冷気通路の風向板45によって、製氷皿収納室39と第一の冷気通路33間を仕切る製氷皿収納室側壁29cの製氷皿収納室開口43に導き、製氷皿27に吹き付けられる。   Further, the first cold air passage 33, the second cold air passage 34, and the third cold air passage 35 are provided between the upper wall 14 a and the ice making frame 29 when the ice making frame 29 is attached to the upper wall 14 a of the ice making chamber 14. Formed. The cold air blown out from the first cold air outlet 31 flows into the first cold air passage 33 and is stored in the ice tray by the wind direction plate 45 of the first cold air passage provided in the first cold air passage 33. It is led to the ice tray storage chamber opening 43 on the side wall 29c of the ice tray storage chamber 29c partitioning the chamber 39 and the first cold air passage 33 and blown to the ice tray 27.

一方、第二の冷気吹き出し口32から第二の冷気通路34側に導かれた冷気は、第二の冷気通路の風向板44により、通気孔29b側の流れと、第三の冷気通路35側の流れとに振り分けられ、製氷皿収納室39、検氷レバー収納室36にそれぞれ流入する。   On the other hand, the cold air led from the second cold air outlet 32 to the second cold air passage 34 side flows by the airflow direction plate 44 of the second cold air passage and the third cold air passage 35 side. And flows into the ice tray storage chamber 39 and the ice detection lever storage chamber 36, respectively.

46は、製氷フレーム29の一部を構成する円弧状部である(図7参照)。この円弧状部46は、製氷皿収納室39の製氷皿27上方面で且つ、該製氷皿27の回動開始側、すなわち、駆動軸26aに沿う方向に製氷区画が二列ある製氷皿27の一列の上方長手方向に設けられている。   Reference numeral 46 denotes an arcuate portion constituting a part of the ice making frame 29 (see FIG. 7). The arc-shaped portion 46 is formed on the ice tray 27 having two rows of ice making sections on the upper surface of the ice tray 27 of the ice tray storage chamber 39 and on the rotation start side of the ice tray 27, that is, along the drive shaft 26a. One row is provided in the upper longitudinal direction.

そして、円弧状部46は、製氷皿収納室側壁29cに形成された製氷皿収納室開口43から製氷皿収納室39に入った冷気が、製氷皿27表面(上面及び側面)に効率的に当たるように導く。すなわち、円弧状部46は、第一の冷気通路33を形成する製氷皿収納室側壁29cに設けた製氷皿収納室開口43より、製氷皿収納室39に吹き込まれた冷気を、図7の矢印に示すように、製氷皿27に沿って導き、製氷皿27内の水をすばやく冷却して、製氷時間を短縮するような構成としている。   The arc-shaped portion 46 allows the cold air entering the ice tray storage chamber 39 from the ice tray storage chamber opening 43 formed in the ice tray storage chamber side wall 29c to efficiently hit the surface (upper surface and side surfaces) of the ice tray 27. Lead to. That is, the arc-shaped portion 46 converts the cold air blown into the ice tray storage chamber 39 from the ice tray storage chamber opening 43 provided in the ice tray storage chamber side wall 29c forming the first cold air passage 33 with the arrow in FIG. As shown in FIG. 5, the water is guided along the ice tray 27 to quickly cool the water in the ice tray 27 to shorten the ice making time.

製氷フレーム29に組み込まれる電動機構部26は、製氷皿27を捻ることで製氷皿27から離氷させる。離氷時には、例えば1〜4N・mのトルクを必要とする。換言すると、製氷フレーム29はこのトルクに耐える強度を必要とする。そこで、本実施形態の製氷フレーム29は、円弧状部46で強度を向上している。また、製氷皿収納室39の両側には、正面から見て断面U字状の第一の冷気通路33、第三の冷気通路35を形成して、剛性を高めている(図8参照)。なお、第一の冷気通路33に比較して断面積の小さい第三の冷気通路35側に、検氷レバー収納室36を設けることで、剛性を高めるとともに、冷気分配のバランスをとっている。   The electric mechanism unit 26 incorporated in the ice making frame 29 is made to ice from the ice making plate 27 by twisting the ice making plate 27. At the time of deicing, for example, a torque of 1 to 4 N · m is required. In other words, the ice making frame 29 needs to be strong enough to withstand this torque. Therefore, the strength of the ice making frame 29 of the present embodiment is improved by the arc-shaped portion 46. Further, a first cold air passage 33 and a third cold air passage 35 having a U-shaped cross section when viewed from the front are formed on both sides of the ice tray storage chamber 39 to enhance rigidity (see FIG. 8). In addition, by providing the ice detecting lever storage chamber 36 on the side of the third cold air passage 35 having a smaller cross-sectional area than the first cold air passage 33, the rigidity is improved and the cold air distribution is balanced.

47は温度センサーである。この温度センサー47は、製氷皿27内で氷ができたかどうかを検知する温度検知手段であり、円弧状部46の終端付近に設けた冷気取り入れ口48の近くに取り付けられている。   47 is a temperature sensor. The temperature sensor 47 is a temperature detection means for detecting whether ice is formed in the ice tray 27, and is attached near a cold air intake 48 provided near the end of the arc-shaped portion 46.

円弧状部46は、製氷フレーム29上面から製氷皿27に近づくように湾曲しており、冷気取り入れ口48は製氷皿27に近い位置の円弧状部46終端付近に設けている。これにより、温度センサー47の検知温度は、製氷皿27内の水温に近いものとなり、より正確な製氷制御となる。   The arc-shaped portion 46 is curved so as to approach the ice tray 27 from the upper surface of the ice making frame 29, and the cold air intake 48 is provided near the end of the arc-shaped portion 46 at a position close to the ice tray 27. As a result, the temperature detected by the temperature sensor 47 is close to the water temperature in the ice tray 27, and the ice making control is more accurate.

また、温度センサー47は、同温度帯である上段冷凍室7a、下段冷凍室7の温度制御を行う温度検知手段を兼ねることもある。この場合、第三の冷気通路35に入る冷気も検知できるようにしておけば、製氷皿27の水温の影響を除いて検知できる。   Further, the temperature sensor 47 may also serve as temperature detection means for controlling the temperature of the upper freezer compartment 7a and the lower freezer compartment 7 in the same temperature range. In this case, if the cold air entering the third cold air passage 35 can also be detected, it can be detected without the influence of the water temperature of the ice tray 27.

製氷皿27内の水は、所定時間冷却すると氷になる。冷気取り入れ口48から温度センサー47側に入る冷気温度は、水の冷却に伴い低くなる。そして、この冷気温度が例えば−10℃以下になって一定時間経過後、製氷完了と制御基板で判断して、製氷皿27を回動し離氷動作を行うように制御する。   The water in the ice tray 27 becomes ice when cooled for a predetermined time. The cold air temperature entering the temperature sensor 47 side from the cold air inlet 48 becomes lower as the water is cooled. Then, after this cold air temperature becomes, for example, −10 ° C. or less and a certain time has elapsed, it is judged by the control board that ice making is completed, and the ice tray 27 is rotated to perform the ice removing operation.

次に、温度センサー47について説明する。温度センサー47は、温度センサー収納部49に収納される。温度センサー収納部49は、第三の冷気通路35先端部、すなわち、第三の冷気通路35の前方に隣接している(図5参照)。また、温度センサー収納部49は、円弧状部46で区画形成された空間である(図7参照)。温度センサー収納部49は、第三の冷気通路35と連通しており、第三の冷気通路35を流れる冷気の一部が流れるように構成されている。   Next, the temperature sensor 47 will be described. The temperature sensor 47 is stored in the temperature sensor storage unit 49. The temperature sensor housing 49 is adjacent to the tip of the third cold air passage 35, that is, in front of the third cold air passage 35 (see FIG. 5). Moreover, the temperature sensor storage part 49 is a space defined by the arc-shaped part 46 (see FIG. 7). The temperature sensor storage portion 49 communicates with the third cold air passage 35 and is configured such that a part of the cold air flowing through the third cold air passage 35 flows.

円弧状部46は製氷皿27が離氷のために回動する回動軌跡よりもわずかに大きな円弧形状をなしており、製氷フレーム29の剛性を向上させるとともに、第一冷気通路33から冷気を効率よく製氷皿27に導く。   The arc-shaped portion 46 has an arc shape that is slightly larger than the rotation trajectory in which the ice tray 27 rotates for deicing, improves the rigidity of the ice making frame 29, and cools air from the first cold air passage 33. Efficiently guide to ice tray 27.

また、円弧状部46は、製氷フレーム上面29aが製氷皿27に近づくように湾曲して構成されている。このため、円弧状部46に形成された温度センサー収納部49内に、冷気取り入れ口48から流入する冷気(大部分が製氷皿27上面を通り、製氷皿27の水又は氷と熱交換した冷気)の温度は、製氷皿27の水或いは氷の温度に近い温度となる。   Further, the arc-shaped portion 46 is configured to be curved so that the ice making frame upper surface 29 a approaches the ice making tray 27. For this reason, cold air (mostly passing through the top surface of the ice tray 27 and heat-exchanged with water or ice in the ice tray 27) flows into the temperature sensor storage portion 49 formed in the arc-shaped portion 46 from the cold air intake port 48. ) Is close to the temperature of water or ice in the ice tray 27.

50は温度センサー収納部49内に導かれる冷気を、温度センサー収納部49外に導く排気孔である。この排気孔50から流出した冷気は、貯氷容器30側に流れていく。   Reference numeral 50 denotes an exhaust hole that guides the cold air introduced into the temperature sensor housing 49 to the outside of the temperature sensor housing 49. The cold air flowing out from the exhaust hole 50 flows toward the ice storage container 30 side.

第三の冷気通路35から温度センサー収納部49に流入する冷気量は、製氷室扉10を開けた時、温度センサー収納部49内に流入する外気によって温度が上がるのを抑制できる程度の量である。従って、温度センサー収納部49は、第三の冷気通路35の先端部に連通させて、検氷レバー収納室36に大半の冷気を送風した残りの冷気が、温度センサー収納部49に入るようにした。換言すると、温度センサー収納部49は、製氷室扉10に近く、冷却器室16から離れた位置であって、製氷皿27よりも上方に設けられている。これにより、温度センサー47の検知精度を向上することができる。   The amount of cold air flowing into the temperature sensor housing part 49 from the third cold air passage 35 is such an amount that it is possible to prevent the temperature from rising due to the outside air flowing into the temperature sensor housing part 49 when the ice making chamber door 10 is opened. is there. Accordingly, the temperature sensor storage unit 49 communicates with the tip of the third cold air passage 35 so that the remaining cold air that has blown most of the cold air into the ice detecting lever storage chamber 36 enters the temperature sensor storage unit 49. did. In other words, the temperature sensor storage portion 49 is provided near the ice making chamber door 10 and at a position away from the cooler chamber 16 and above the ice making tray 27. Thereby, the detection accuracy of the temperature sensor 47 can be improved.

自動製氷機における給水、製氷、離氷は、次のようにして行われる。貯水タンク24内の水は、ポンプ(図示せず)等によって一定量、製氷皿27に給水する。給水された製氷皿27内の水の温度は、給水直後は冷蔵室6内の温度と同じであるが、第一の冷気通路33、第二の冷気通路34を通して送風される冷気により冷却され、所定時間経過後氷となる。その間、温度センサー47は、冷気取り入れ口48からの冷気温度を検知して、制御基板(図示せず)に信号を送る。   Water supply, ice making, and ice removal in an automatic ice maker are performed as follows. A certain amount of water in the water storage tank 24 is supplied to the ice tray 27 by a pump (not shown) or the like. The temperature of the supplied water in the ice tray 27 is the same as that in the refrigerator compartment 6 immediately after the water supply, but is cooled by the cold air blown through the first cold air passage 33 and the second cold air passage 34, It becomes ice after a predetermined time. In the meantime, the temperature sensor 47 detects the cold air temperature from the cold air inlet 48 and sends a signal to a control board (not shown).

製氷温度(水から氷への状態変化の温度)で一定時間経過した後、制御基板は電動機構部26を動作させる。電動機構部26が動作すると、まず検氷レバー28が動作し、貯氷容器30内が満氷になっているかどうかを検知する。貯氷容器30内が満氷の場合には離氷を行うことなく製氷皿27は待機するが、満氷でない場合には製氷皿27を製氷位置から離氷位置まで回動し、ひねり動作を行い、製氷皿27の氷を貯氷容器30内に落とす。   After a certain period of time has elapsed at the ice making temperature (temperature of change of state from water to ice), the control board operates the electric mechanism unit 26. When the electric mechanism unit 26 operates, the ice detecting lever 28 operates first to detect whether or not the ice storage container 30 is full of ice. When the ice storage container 30 is full of ice, the ice tray 27 waits without performing ice separation, but when it is not full, the ice tray 27 is rotated from the ice making position to the ice separating position, and a twisting operation is performed. Then, the ice in the ice tray 27 is dropped into the ice storage container 30.

この後、製氷皿27は製氷位置に戻り、貯水タンク24から給水を受けて再度製氷を行う。この動作を繰り返すことで、貯氷容器30内に氷を確保する。   Thereafter, the ice tray 27 returns to the ice making position and receives ice from the water storage tank 24 to make ice again. By repeating this operation, ice is secured in the ice storage container 30.

製氷室扉10開閉時に検氷レバー28に成長した霜は、第三の冷気通路35から検氷レバー収納室36内に吹き出される冷気により昇華され、検氷レバー28には霜がない状態を維持する。   The frost that has grown on the ice detecting lever 28 when the ice making chamber door 10 is opened and closed is sublimated by the cold air blown into the ice detecting lever storage chamber 36 from the third cold air passage 35, and the ice detecting lever 28 has no frost. maintain.

本発明は以上説明した構成を有するから、次の効果が得られる。すなわち、貯氷量を検知する検氷レバーと、該検氷レバーで貯氷量不足を検知した場合に製氷皿を回転駆動して離氷する電動機構部と、を有する自動製氷機を備えた冷蔵庫において、前記自動製氷機は製氷フレームを備え、該製氷フレームは、前記製氷皿を収納する製氷皿収納室と、前記製氷皿収納室と区画されて前記検氷レバーを収納する検氷レバー収納室と、が形成されて、前記製氷皿収納室の側部から冷気を導く第一の冷気通路と、前記検氷レバー収納室に冷気を導く第三の冷気通路と、前記製氷皿収納室の上部及び前記第三の冷気通路に冷気を導く第二の冷気通路と、を備える。   Since the present invention has the configuration described above, the following effects can be obtained. That is, in a refrigerator equipped with an automatic ice maker having an ice detecting lever for detecting an ice storage amount, and an electric mechanism portion for rotating and deicing an ice tray when the ice detection lever detects that the ice storage amount is insufficient. The automatic ice maker includes an ice making frame, and the ice making frame includes an ice making tray storage chamber for storing the ice tray, and an ice detection lever storage chamber that is partitioned from the ice tray storage chamber and stores the ice detection lever. Is formed, a first cold air passage for guiding cold air from the side of the ice tray storage chamber, a third cold air passage for guiding cold air to the ice detecting lever storage chamber, an upper portion of the ice tray storage chamber, and A second cold air passage for guiding cold air to the third cold air passage.

これにより、検氷レバーが製氷皿への冷気供給を阻害しないので、製氷能力の向上が図れる。また、検氷レバー収納室内へ低湿度の冷気を容易に導入できるので、検氷レバー収納室内での冷気滞留を抑制して検氷レバーへの霜付きを回避できる。よって、検氷レバーに霜が付き、正確な検氷ができなくなることを抑制できる。   As a result, the ice detection lever does not hinder the supply of cold air to the ice tray, so that the ice making capacity can be improved. Moreover, since low-humidity cold air can be easily introduced into the ice detection lever storage chamber, it is possible to suppress the cold air from staying in the ice detection lever storage chamber and avoid frost formation on the ice detection lever. Therefore, it can be suppressed that frost is formed on the ice detecting lever and accurate ice detection cannot be performed.

また、製氷皿収納室を挟んで第一の冷気通路、第三の冷気通路を形成しているので、製氷フレーム自体の強度を向上できる。   Further, since the first cold air passage and the third cold air passage are formed across the ice tray storage chamber, the strength of the ice making frame itself can be improved.

また、前記第二の冷気通路は、前記電動機構部の上部に設けられ、前記製氷皿収納室及び前記第三の冷気通路に冷気を分配する風向板を備える。これにより、長方形状の製氷皿全体への冷気導入が容易となり、冷却ムラを抑制できる。   The second cold air passage is provided at an upper portion of the electric mechanism unit, and includes a wind direction plate that distributes the cold air to the ice tray storage chamber and the third cold air passage. This facilitates the introduction of cold air to the entire rectangular ice tray, and can suppress uneven cooling.

また、前記検氷レバー収納室側壁に検氷レバー収納室開口が形成されて、前記第三の冷気通路から前記検氷レバー収納室開口を通過した冷気が前記検氷レバー収納室に導かれる。これにより、検氷レバー収納室内全体の冷気滞留を抑制して、検氷レバー部への霜付きを回避できる。   In addition, an ice detection lever storage chamber opening is formed on the side wall of the ice detection lever storage chamber, and the cold air that has passed through the ice detection lever storage chamber opening from the third cold air passage is guided to the ice detection lever storage chamber. Thereby, it is possible to suppress the cold air staying in the entire ice detecting lever storage chamber and to avoid the frost on the ice detecting lever portion.
