Description

本発明は、自動製氷装置を有する冷蔵庫に関する。   The present invention relates to a refrigerator having an automatic ice making device.

冷蔵庫には、自動製氷装置を有したものがある。従来の自動製氷装置を備えた冷蔵庫は、冷蔵室に給水タンクを設け、冷蔵室の直下に製氷室を配置し、製氷室に製氷皿と貯氷箱を設けている。製氷室内の温度は、製氷や氷の保存を目的として−18℃に設定されている。   Some refrigerators have an automatic ice making device. A refrigerator equipped with a conventional automatic ice making device has a water supply tank in a refrigerating room, an ice making room arranged immediately below the refrigerating room, and an ice making tray and an ice storage box in the ice making room. The temperature in the ice making chamber is set to −18 ° C. for the purpose of ice making and ice storage.

給水タンク内の水は、ポンプの運転によって給水パイプの吸入部内を汲み上げられ、汲み上げられた水は、自重によって吐出パイプを流れて製氷皿へと給水される。すなわち、給水タンクと給水パイプと吐出パイプとは連通され、給水経路を形成している。製氷皿へと給水された水は、製氷室内に供給される冷気によって凝固した後、自動製氷装置の駆動装置によって製氷皿が回転(上下反転)させられながら捩られることで、製氷皿から離氷され、貯氷箱に落下する。   The water in the water supply tank is pumped up in the suction portion of the water supply pipe by the operation of the pump, and the pumped water flows through the discharge pipe by its own weight and is supplied to the ice tray. That is, the water supply tank, the water supply pipe, and the discharge pipe are communicated to form a water supply path. The water supplied to the ice tray is solidified by the cold air supplied to the ice making chamber and then twisted while the ice tray is rotated (inverted upside down) by the automatic ice maker drive device. And fall into the ice box.

貯氷箱は、製氷室扉を開けることによって製氷室扉と共に前方へ引き出され、その内部の氷を取り出すことができる。   The ice storage box is pulled forward together with the ice making room door by opening the ice making room door, and the ice inside the ice storage box can be taken out.

このようなものにおいて、製氷室扉を閉めた際に貯氷箱の奥側が自動製氷装置の駆動装置の下へ配置されるようにしたものがある。これによって、貯氷箱内に積もった氷が、製氷室扉を閉めた際の反動で上へ動いても、自動製氷装置の駆動装置に当たり、貯氷箱の外へ落下するのが防止される(例えば、特許文献1参照)。   In such a thing, when the ice making room door is closed, the back side of the ice storage box is arranged below the driving device of the automatic ice making device. As a result, even if the ice accumulated in the ice storage box moves up due to the reaction when the ice making room door is closed, it is prevented from hitting the driving device of the automatic ice making apparatus and falling out of the ice storage box (for example, , See Patent Document 1).

特開2013−057483号公報(図2、図4)JP2013-057483A (FIGS. 2 and 4)

しかしながら、製氷室扉を閉めた際の反動で上へ動く氷を自動製氷装置の駆動装置に当てることで、氷が貯氷箱の外へ落下するのを防止したものにあっては、自動製氷装置の駆動装置の位置によって貯氷箱の奥行き寸法が決定される。このため、自動製氷装置の駆動装置よりも後ろへ貯氷箱を延ばすことができず、貯氷箱の容積が小さくなる問題があった。   However, if the ice that moves up by the reaction when the ice making room door is closed is applied to the driving device of the automatic ice making device, it will prevent the ice from falling out of the ice storage box. The depth dimension of the ice storage box is determined by the position of the drive unit. For this reason, there has been a problem that the ice storage box cannot be extended behind the drive unit of the automatic ice making device, and the volume of the ice storage box is reduced.

本発明は、前記のような課題を解決するためになされたもので、貯氷箱の氷が落下するのを防止しつつ、貯氷箱の容積を大きくできる冷蔵庫を提供することを目的としている。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a refrigerator that can increase the volume of the ice storage box while preventing the ice in the ice storage box from falling.

本発明に係る冷蔵庫は、冷蔵庫の製氷室に引出し自在に設けられた貯氷箱と、貯氷箱の上方にて、後方端部が駆動装置に接続され、離氷時には駆動装置によって上下反転させられながら捩られ、氷箱へ氷を供給する製氷皿と、貯氷箱内部の氷の量を検知する氷検知レバーと、駆動装置の背面側に設けられ、貯氷箱の上方を覆う氷脱落防止部と、を備え、駆動装置及び製氷皿は、貯氷箱の幅方向の一側側に配置され、氷検知レバーは、貯氷箱の幅方向の他側側にて駆動装置に取り付けられており、氷脱落防止部は、駆動装置の背面側から駆動装置の氷検知レバーが取り付けられている側の側面にかけて配置されているものである。 The refrigerator according to the present invention has an ice storage box provided in an ice making chamber of the refrigerator so that it can be pulled out, and a rear end is connected to the drive device above the ice storage box, and is turned upside down by the drive device at the time of deicing. twisted, and ice tray supplying ice to the savings ice box, and ice detection lever for detecting the amount of ice box inside the ice, is provided on the rear side of the drive unit, and ice disengagement prevention part for covering the upper ice box The ice and the ice tray are arranged on one side in the width direction of the ice storage box, and the ice detection lever is attached to the drive device on the other side in the width direction of the ice box, and the ice drops out. The prevention part is arranged from the back side of the drive device to the side surface of the drive device on which the ice detection lever is attached .

本発明に係る冷蔵庫においては、駆動装置の背面側に貯氷箱の上方を覆う氷脱落防止部を設けているので、製氷室扉を閉めた際の反動で上へ動く氷を自動製氷装置の駆動装置及び氷脱落防止部に当てることができ、氷が貯氷箱の外へ落下するのを防止することができる。このため、氷脱落防止部の部位まで貯氷箱の奥行き寸法を延ばすことができ、貯氷箱の容積を大きくできる。   In the refrigerator according to the present invention, since the ice drop prevention portion that covers the upper side of the ice storage box is provided on the back side of the drive device, the ice that moves upward by the reaction when the ice making room door is closed is driven by the automatic ice making device. It can be applied to the device and the ice dropout prevention unit, and ice can be prevented from falling out of the ice storage box. For this reason, the depth dimension of an ice storage box can be extended to the site | part of an ice drop-off prevention part, and the volume of an ice storage box can be enlarged.

FIG. 1 is a front view of a refrigerator according to Embodiment 1 of the present invention. FIG. 2 is a cross-sectional view in side view of the refrigerator according to the first embodiment of the present invention.
As shown in FIG. 2, the refrigerator 100 is formed by filling a heat insulating material 3 between a steel-made outer box 1 and a resin-made inner box 2, and has an opening having one surface (front surface) opened. The main body 101 (insulation box) is provided. The inside of the main body 101 is partitioned into a plurality of chambers by a first heat insulating partition wall 80a to a third heat insulating partition wall 80c. As shown in FIG. 1 and FIG. An ice making room B1, a switching room B2, a freezing room C, and a vegetable room D are formed on the left and right sides.

図1に示すように、冷蔵室Aの前面開口部には、正面から見て回転式の冷蔵室左扉10a及び冷蔵室右扉10b(所謂、観音扉)が開閉自在に取り付けられている。冷蔵室左扉10aの左右の幅は、冷蔵室右扉10bのそれよりも短い。すなわち、冷蔵室左扉10aの左右の幅は、製氷室B1の製氷室扉20の左右の幅と同じになるようにしている。一方、冷蔵室右扉10bの左右の幅は、切替室B2の切替室扉30の左右の幅と同じになるようにしている。   As shown in FIG. 1, a refrigerating room left door 10a and a refrigerating room right door 10b (so-called sound doors) are attached to the front opening of the refrigerating room A so as to be openable and closable as viewed from the front. The left and right width of the refrigerator compartment left door 10a is shorter than that of the refrigerator compartment right door 10b. That is, the left and right widths of the refrigerator compartment left door 10a are set to be the same as the left and right widths of the ice making chamber door 20 of the ice making chamber B1. On the other hand, the left and right widths of the refrigerator compartment right door 10b are set to be the same as the left and right widths of the switching chamber door 30 of the switching chamber B2.

製氷室B1の前面開口部は、図2に示すように、引き出し式の製氷室扉20が開閉自在に覆っている。引き出し式の製氷室扉20には、内側に貯氷箱20aを載置するフレーム20bが固定されている。貯氷箱20aは、製氷室扉20を開けることによって、製氷室扉20と共に前方へ引き出され、その内部の氷を取り出すことができる。   As shown in FIG. 2, the front opening of the ice making chamber B1 is covered with a drawer-type ice making chamber door 20 so as to be freely opened and closed. A frame 20b on which the ice storage box 20a is placed is fixed to the drawer type ice making chamber door 20 inside. The ice storage box 20a can be drawn forward together with the ice making room door 20 by opening the ice making room door 20, and the ice inside thereof can be taken out.

切替室B2の前面開口部は、図1のように引き出し式の切替室扉30が開閉自在に覆っている。引き出し式の切替室扉30の内側は、上面が開口した収納室になっている。   As shown in FIG. 1, the front opening of the switching chamber B2 is covered with a pull-out switching chamber door 30 so as to be freely opened and closed. The inside of the drawer-type switching chamber door 30 is a storage chamber whose upper surface is open.

野菜室Dの前面開口部は、図1及び図2のように引き出し式の野菜室扉50が開閉自在に覆っている。   The front opening of the vegetable compartment D is covered with a drawer-type vegetable compartment door 50 as shown in FIGS.

図3は図2の要部詳細拡大図である。
冷蔵室Aと製氷室B1及び切替室B2との間は、図2及び図3に示すように、断熱性を有する第1の断熱仕切壁80aで仕切られている。この第1の断熱仕切壁80aには、給水装置60の吐出パイプ64が配置される貫通穴81が開けられている。給水装置60は、冷蔵室Aに給水タンク61を有する。給水タンク内の水は、ポンプ62の運転によって給水パイプ63の吸入部内を汲み上げられ、汲み上げられた水は、自重によって吐出パイプ64を流れて、製氷室B1内の自動製氷装置70の製氷皿71へと給水される。すなわち、給水タンク61と給水パイプ63と吐出パイプ64とは、連通され、給水経路を形成している。
FIG. 3 is a detailed enlarged view of a main part of FIG.
As shown in FIGS. 2 and 3, the refrigerator compartment A, the ice making room B1, and the switching room B2 are partitioned by a first heat insulating partition wall 80a having heat insulating properties. The first heat insulating partition wall 80a is provided with a through hole 81 in which the discharge pipe 64 of the water supply device 60 is disposed. The water supply device 60 has a water supply tank 61 in the refrigerator compartment A. The water in the water supply tank is pumped up in the suction portion of the water supply pipe 63 by the operation of the pump 62, and the pumped water flows through the discharge pipe 64 by its own weight, and the ice making tray 71 of the automatic ice making device 70 in the ice making chamber B1. Water is supplied to That is, the water supply tank 61, the water supply pipe 63, and the discharge pipe 64 are communicated to form a water supply path.

製氷室B1及び切替室B2と冷凍室Cとの間は、図2のように断熱性を有する第2の断熱仕切壁80bで仕切られている。   The ice making room B1 and the switching room B2 and the freezing room C are partitioned by a second heat insulating partition wall 80b having heat insulating properties as shown in FIG.

冷凍室Cと野菜室Dとの間は、断熱性を有する第3の断熱仕切壁80cで仕切られている。   The freezer compartment C and the vegetable compartment D are partitioned by a third heat insulating partition wall 80c having heat insulating properties.

冷蔵室Aの内部は、複数の棚が設けられ、食品が多段に収納できるように設けられている。   The inside of the refrigerator compartment A is provided with a plurality of shelves so that food can be stored in multiple stages.

製氷室B1内の上部には、図2及び図3に示すように、冷気の風路76を有し、奥行き方向に延びる上板73が設けられている。上板73は、自動製氷装置70の駆動装置72を保持している。駆動装置72には、自動製氷装置70を構成する製氷皿71の後方端部が接続されている。製氷皿71の前方端部は、上板73に回動自在に支持されている。駆動装置72及び製氷皿71は、貯氷箱20aの幅方向の一側側にて、正面から見た貯氷箱20aの投影範囲内に配置されている。したがって、貯氷箱20aの奥側の壁の上縁には、貯氷箱20aを引き出す際に駆動装置72が干渉しないように逃がし部(凹部)が設けられている。すなわち、駆動装置72が貯氷箱20aの奥側の壁に設けた逃がし部を通過することで、貯氷箱20aは前方へ引き出すことができる。製氷皿71には、第1の断熱仕切壁80aの貫通穴81に挿通された吐出パイプ64を介して、給水装置60から給水される。製氷皿71には製氷時に上板73から冷気が供給され、離氷時には離氷されて貯氷箱20aへ氷を供給する。   As shown in FIGS. 2 and 3, an upper plate 73 having a cold air passage 76 and extending in the depth direction is provided in the upper part of the ice making chamber B1. The upper plate 73 holds the drive device 72 of the automatic ice making device 70. The driving device 72 is connected to the rear end of an ice tray 71 that constitutes the automatic ice making device 70. The front end of the ice tray 71 is rotatably supported by the upper plate 73. The drive device 72 and the ice tray 71 are arranged on one side in the width direction of the ice storage box 20a within the projection range of the ice storage box 20a as viewed from the front. Therefore, an escape portion (concave portion) is provided on the upper edge of the wall on the far side of the ice storage box 20a so that the drive device 72 does not interfere when the ice storage box 20a is pulled out. That is, the ice storage box 20a can be pulled out forward by the drive device 72 passing through the escape portion provided on the back wall of the ice storage box 20a. The ice tray 71 is supplied with water from the water supply device 60 through a discharge pipe 64 inserted through the through hole 81 of the first heat insulating partition wall 80a. The ice tray 71 is supplied with cold air from the upper plate 73 at the time of ice making, and is de-iced at the time of ice removal to supply ice to the ice storage box 20a.

図4は本発明の実施形態1に係る冷蔵庫の自動製氷装置の駆動装置と氷検知レバーと氷脱落防止部と貯氷箱との関係を示す斜視図である。図5は本発明の実施形態1に係る冷蔵庫の自動製氷装置を下方から見た拡大斜視図である。貯氷箱20aの幅方向の他側側にて、自動製氷装置70の駆動装置72には、図4及び図5に示すように、上方及び側方に屈曲した氷検知レバー74が揺動できるように取り付けられている。そのため、貯氷箱20aの奥側の壁の上縁には、貯氷箱20aを引き出す際に氷検知レバー74が干渉しないように逃がし部(凹部)が設けられている。すなわち、氷検知レバー74が貯氷箱20aの奥側の壁に設けた逃がし部を通過することで、貯氷箱20aは前方へ引き出すことができる。貯氷箱20a内に氷がある場合は、氷検知レバー74が予め決められた位置まで下がらないため、氷があることを検知することができる。製氷皿71に貯留された水が凍ったことは、図示しない製氷検知手段によって検知される。水が凍ったことが検知され、かつ氷検知レバー74によって貯氷箱20a内に氷が無い、あるいは一定量以下の氷しか存在していないと検知された場合は、駆動装置72によって離氷動作が行われる。離氷動作は、製氷皿71を上下反転させるように回転させながら捩る動作であり、製氷皿71を捩る動作は、例えば上板73の製氷皿71の支持部に、製氷皿71が上下反転させられたときに係合するストッパを設け、製氷皿71の他端側の回動を規制することで行う。もしくは、製氷皿71が上下反転状態下で、駆動装置72の往復逆転動作を数秒間繰り返すことで行われる。これによって氷が製氷皿71から離れ、下方に落下し、貯氷箱20aに貯留される。   FIG. 4 is a perspective view showing the relationship among the drive unit of the automatic ice making device for the refrigerator, the ice detection lever, the ice dropout prevention unit, and the ice storage box according to Embodiment 1 of the present invention. FIG. 5 is an enlarged perspective view of the automatic ice making device for a refrigerator according to Embodiment 1 of the present invention as viewed from below. On the other side in the width direction of the ice storage box 20a, the driving device 72 of the automatic ice making device 70 can swing an ice detecting lever 74 bent upward and laterally as shown in FIGS. Is attached. Therefore, an escape portion (concave portion) is provided on the upper edge of the wall on the far side of the ice storage box 20a so that the ice detection lever 74 does not interfere when the ice storage box 20a is pulled out. In other words, the ice storage box 20a can be pulled forward by passing the ice detecting lever 74 through the escape portion provided on the inner wall of the ice storage box 20a. When there is ice in the ice storage box 20a, the ice detection lever 74 does not go down to a predetermined position, so that it can be detected that there is ice. The fact that the water stored in the ice tray 71 is frozen is detected by an ice making detection means (not shown). When it is detected that the water is frozen and the ice detection lever 74 detects that there is no ice in the ice storage box 20a or only a certain amount of ice is present, the drive device 72 performs the ice removing operation. Done. The ice removing operation is an operation of twisting the ice tray 71 while rotating it upside down. The operation of twisting the ice tray 71 is performed by, for example, turning the ice tray 71 upside down on the support portion of the ice tray 71 of the upper plate 73. This is done by providing a stopper that is engaged when the ice tray 71 is turned and by restricting the rotation of the other end of the ice tray 71. Alternatively, it is performed by repeating the reciprocating reverse operation of the driving device 72 for several seconds while the ice tray 71 is in the upside down state. As a result, the ice leaves the ice tray 71, falls downward, and is stored in the ice storage box 20a.

冷却器室カバー91における製氷室B1側の面には、製氷室B1内の温度を検知する製氷室温度検知用サーミスタ93が設けられている。また、冷却器室カバー91における切替室B2側の面には、切替室B2内の温度を検知する切替室温度検知用サーミスタ94が設けられている。   An ice making chamber temperature detecting thermistor 93 for detecting the temperature in the ice making chamber B1 is provided on the surface of the cooler chamber cover 91 on the ice making chamber B1 side. A switching chamber temperature detection thermistor 94 that detects the temperature in the switching chamber B2 is provided on the surface of the cooler chamber cover 91 on the switching chamber B2 side.

図2及び図3に示すように、冷蔵室Aの下部、つまり冷蔵室Aの冷蔵室左扉10aに設けた物品収納ポケット10cと対向する位置に給水装置60が配置され、製氷室B1に給水装置60から水が供給されて製氷を行う自動製氷装置70が配置されている。給水装置60を構成する給水タンク61は、使用者が外部に引き出すことができ、洗浄することができる。また、給水タンク61よりも先の水受け部65及び吐出パイプ64も簡単に取り外すことができ、洗浄することができる。   As shown in FIGS. 2 and 3, a water supply device 60 is arranged at a lower portion of the refrigerator compartment A, that is, at a position facing the article storage pocket 10 c provided in the refrigerator compartment left door 10 a of the refrigerator compartment A, and water is supplied to the ice making compartment B <b> 1. An automatic ice making device 70 for making ice by supplying water from the device 60 is disposed. A water supply tank 61 constituting the water supply device 60 can be pulled out by the user and washed. Moreover, the water receiving part 65 and the discharge pipe 64 ahead of the water supply tank 61 can also be removed easily and can be cleaned.

その他の構成は、一般的な冷蔵庫と同じなので概要を簡単に説明するにとどめる。すなわち、冷媒を圧縮する圧縮機(例えば、往復式圧縮機)を用いた冷凍サイクルによって冷気を生成し、その冷気によって各貯蔵室を冷却する。圧縮機は、冷蔵庫100の底部付近の機械室(本体101の外部)に設置される。圧縮機で圧縮された高温・高圧の冷媒ガスは、凝縮器で冷却されて高圧の液冷媒になり、さらに減圧装置(通常は、キャピラリーチューブ)で減圧されて低圧の二相冷媒になる。低圧の二相冷媒は、蒸発器(冷却器)で冷蔵庫100の各貯蔵室を冷却することで、低圧のガス冷媒となり、圧縮機に戻る。このサイクルを繰り返す。   Since the other configuration is the same as that of a general refrigerator, only a brief description will be given. That is, cold air is generated by a refrigeration cycle using a compressor that compresses refrigerant (for example, a reciprocating compressor), and each storage chamber is cooled by the cold air. The compressor is installed in a machine room (outside the main body 101) near the bottom of the refrigerator 100. The high-temperature and high-pressure refrigerant gas compressed by the compressor is cooled by a condenser to become a high-pressure liquid refrigerant, and further depressurized by a decompression device (usually a capillary tube) to become a low-pressure two-phase refrigerant. The low-pressure two-phase refrigerant is converted into a low-pressure gas refrigerant by cooling each storage chamber of the refrigerator 100 with an evaporator (cooler), and returns to the compressor. Repeat this cycle.

冷蔵庫100では、例えば図2に示すように、冷凍室Cの背面に冷却器室カバー91によって冷却空間90が形成されている。冷却空間90内には、冷却器(図示せず)が配置されている。また、冷却器室カバー91には、送風機(図示せず)が備えられている。冷却器で生成された冷気が、送風機で各室に送られる。各室の温度は、冷気の風量をダンパーによって制御することで、設定された温度に制御される。   In the refrigerator 100, for example, as illustrated in FIG. 2, a cooling space 90 is formed by a cooler chamber cover 91 on the back surface of the freezing chamber C. A cooler (not shown) is arranged in the cooling space 90. The cooler chamber cover 91 is provided with a blower (not shown). Cold air generated by the cooler is sent to each chamber by a blower. The temperature of each chamber is controlled to a set temperature by controlling the air volume of the cool air with a damper.

冷却器室カバー91には、図2〜図4に示すように、冷却空間90の冷気を案内するための冷気吐出部92が設けられ、冷気吐出部92が上板73の風路76に連結風路78を介して接続されている。風路76から製氷皿71に吹き出された冷気によって製氷皿71内部の水が凍結される。   As shown in FIGS. 2 to 4, the cooler chamber cover 91 is provided with a cool air discharge portion 92 for guiding the cool air in the cooling space 90, and the cool air discharge portion 92 is connected to the air path 76 of the upper plate 73. They are connected via an air path 78. The water inside the ice tray 71 is frozen by the cold air blown from the air passage 76 to the ice tray 71.

上板73には、図3〜図5に示すように、駆動装置72の背面側からこの駆動装置72の氷検知レバー74が取り付けられている側の側面にかけて貯氷箱20aの上方を覆う箱状の氷脱落防止部75が設けられている。氷脱落防止部75における駆動装置72の背面側の部分75a(図3及び図5)は、上方の連結風路78を避けるように設けられているため、図4に示す氷脱落防止部75の角度の位置からは見えない。氷脱落防止部75における駆動装置72の側面側の部分75bは、前方に突出して形成されている。なお、ここでは、上板73、連結風路78、氷脱落防止部75、駆動装置72の保持部、及び製氷皿71の支持部が、一体に成形されている。   As shown in FIGS. 3 to 5, the upper plate 73 has a box shape covering the upper side of the ice storage box 20 a from the back side of the driving device 72 to the side surface of the driving device 72 on which the ice detection lever 74 is attached.
