製氷皿嵌合部品（左）６ａ及び製氷皿嵌合部品（右）６ｂの材料は、ＰＯＭ（ポリアセタール）である。ＰＯＭ（ポリアセタール）は、オキシメチレン（ｏｘｙｍｅｔｈｙｌｅｎｅ、ＣＨ_２Ｏ）構造を単位構造にもつポリマーである。ポリアセタールは非晶部分と結晶部分が混在するために、強度、弾性率、耐衝撃性に優れたエンジニアリングプラスチックである。また摺動特性に優れている為、軸受け部品としても利用されている。 The material of the ice tray fitting component (left) 6a and the ice tray fitting component (right) 6b is POM (polyacetal). POM (polyacetal) is a polymer having an oxymethylene (CH ₂ O) structure as a unit structure. Polyacetal is an engineering plastic with excellent strength, elastic modulus, and impact resistance because of the presence of amorphous and crystalline parts. Also, because of its excellent sliding characteristics, it is also used as a bearing part.

製氷皿嵌合部品（左）６ａには円弧状のバネ形状部６ａ−４を備えるので、製氷皿嵌合部品（左）６ａ（製氷皿嵌合部品（右）６ｂも同様）の材料には、強度、弾性率、耐衝撃性に優れたエンジニアリングプラスチックであるＰＯＭ（ポリアセタール）が適する。 Since the ice tray fitting component (left) 6a is provided with an arcuate spring-shaped portion 6a-4, the material of the ice tray fitting component (left) 6a (the same for the ice tray fitting component (right) 6b) is used. POM (polyacetal) which is an engineering plastic excellent in strength, elastic modulus and impact resistance is suitable.

製氷皿１の皿部１ａ、ハンドル部１ｂの材料は、例えば、ＰＰ（ポリプロピレン樹脂）である。 The material of the tray part 1a and the handle part 1b of the ice tray 1 is, for example, PP (polypropylene resin).

図１２乃至図１４は実施の形態１を示す図で、図１２は製氷コーナー部１０の前面側端部の拡大断面図、図１３は図１２のＢ部拡大図、図１４は図１２のＣ部拡大図である。 12 to 14 are diagrams showing the first embodiment. FIG. 12 is an enlarged cross-sectional view of the front side end portion of the ice making corner portion 10, FIG. 13 is an enlarged view of portion B of FIG. 12, and FIG. FIG.

図１２乃至図１４を参照しながら製氷皿１のハンドル部１ｂと製氷皿嵌合部品（左）６ａ及び製氷皿嵌合部品（右）６ｂとの嵌合構造（係合構造）について、製氷皿嵌合部品（左）６ａを例に説明する（ハンドル部１ｂと製氷皿嵌合部品（右）６ｂの嵌合構造（係合構造）も同様の構成である）。図１２は製氷皿１のハンドル部１ｂが製氷皿嵌合部品（左）６ａに係合している状態を示している。製氷皿１のハンドル部１ｂは、以下に示す製氷皿嵌合部品（左）６ａの二箇所に係合している。
（１）ハンドル部１ｂの第１の爪形状部１ｂ−２が、製氷皿嵌合部品６ａ（左）の略円形凸形状部６ａ−３に係合している（図１３）；
（２）ハンドル部１ｂの第２の爪形状部１ｂ−３が、製氷皿嵌合部品（左）６ａの凸形状部６ａ−５及び円弧状のバネ形状部６ａ−４に係合している（図１４）。 With reference to FIGS. 12 to 14, the ice tray 1 will be described with respect to the fitting structure (engagement structure) between the handle 1 b of the ice tray 1, the ice tray fitting component (left) 6 a and the ice tray fitting component (right) 6 b. The fitting part (left) 6a will be described as an example (the fitting structure (engaging structure) of the handle portion 1b and the ice tray fitting part (right) 6b has the same configuration). FIG. 12 shows a state where the handle portion 1b of the ice tray 1 is engaged with the ice tray fitting component (left) 6a. The handle portion 1b of the ice tray 1 is engaged with two locations of the ice tray fitting component (left) 6a shown below.
(1) The first claw-shaped portion 1b-2 of the handle portion 1b is engaged with the substantially circular convex-shaped portion 6a-3 of the ice tray fitting component 6a (left) (FIG. 13);
(2) The second claw-shaped portion 1b-3 of the handle portion 1b is engaged with the convex-shaped portion 6a-5 and the arc-shaped spring-shaped portion 6a-4 of the ice tray fitting component (left) 6a. (FIG. 14).

図１２の製氷皿１のハンドル部１ｂが製氷皿嵌合部品（左）６ａに係合している状態から、図１２の矢印の方向に力が加わると、略円形凸形状部６ａ−３を回転軸としてハンドル部１ｂが回転する。すると、第２の爪形状部１ｂ−３がバネ形状部６ａ−４を押し下げて凸形状部６ａ−５から外れる。この状態になると、第１の爪形状部１ｂ−２と略円形凸形状部６ａ−３との係合も容易に外れるので、製氷皿１を製氷皿保持枠体３から引き出すことができる。 When force is applied in the direction of the arrow in FIG. 12 from a state where the handle portion 1b of the ice tray 1 in FIG. 12 is engaged with the ice tray fitting component (left) 6a, the substantially circular convex shape portion 6a-3 is formed. The handle portion 1b rotates as a rotation axis. Then, the 2nd nail | claw-shaped part 1b-3 pushes down the spring-shaped part 6a-4, and remove | deviates from the convex-shaped part 6a-5. If it will be in this state, since engagement with the 1st nail | claw shape part 1b-2 and the substantially circular convex-shaped part 6a-3 will also remove | deviate easily, the ice-making tray 1 can be pulled out from the ice-making tray holding frame 3. FIG.

尚、上述の説明では、製氷皿嵌合部品（左）６ａ及び製氷皿嵌合部品（右）６ｂは、製氷皿保持枠体３とは別部品とした。その理由は、以下の通りである。
（１）バネ形状部６ａ−４は、強度、弾性率、耐衝撃性に優れたエンジニアリングプラスチックであるＰＯＭ（ポリアセタール）が適する；
（２）但し、ＰＯＭ（ポリアセタール）は、ＰＳ（ポリスチレン樹脂）等に比べるとコストが高い；
（３）従って、強度及びコストの両方を満足させるには、製氷皿嵌合部品６をＰＯＭ（ポリアセタール）で作り、製氷皿保持枠体３をＰＳ（ポリスチレン樹脂）等で作るのが好ましい。 In the above description, the ice tray fitting part (left) 6 a and the ice tray fitting part (right) 6 b are separate parts from the ice tray holding frame 3. The reason is as follows.
(1) POM (polyacetal) that is an engineering plastic excellent in strength, elastic modulus, and impact resistance is suitable for the spring-shaped portion 6a-4;
(2) However, POM (polyacetal) is more expensive than PS (polystyrene resin) or the like;
(3) Therefore, in order to satisfy both strength and cost, it is preferable that the ice tray fitting part 6 is made of POM (polyacetal) and the ice tray holding frame 3 is made of PS (polystyrene resin) or the like.

但し、ＰＯＭ（ポリアセタール）を材料として、製氷皿嵌合部品（左）６ａ及び製氷皿嵌合部品（右）６ｂと製氷皿保持枠体３とを一体で成形することでもよい。この場合、製氷皿嵌合部品（左）６ａ及び製氷皿嵌合部品（右）６ｂのみＰＯＭ（ポリアセタール）で作製する場合に比べて割高になる。 However, the ice tray fitting part (left) 6a and the ice tray fitting part (right) 6b and the ice tray holding frame 3 may be integrally formed using POM (polyacetal) as a material. In this case, only the ice tray fitting part (left) 6a and the ice tray fitting part (right) 6b are expensive as compared with the case of making with POM (polyacetal).

製氷コーナー部１０は、以上のように構成されるが、本実施の形態の最大の特徴は、製氷皿１の有無を磁気的に検知し、高湿度条件下でも安定して皿無し時の給水動作を防ぐことができるとともに、製氷皿１が定位置にまで挿入されていない半挿入状態での給水動作よび製氷皿１のひねり動作を防ぐことができる点にある。 Although the ice making corner portion 10 is configured as described above, the greatest feature of the present embodiment is that the presence or absence of the ice making tray 1 is magnetically detected, and water supply is stably performed even under high humidity conditions when there is no tray. The operation can be prevented, and the water supply operation and the twisting operation of the ice tray 1 in the half-inserted state where the ice tray 1 is not inserted to the fixed position can be prevented.

図１５乃至図２２は実施の形態１を示す図で、図１５は製氷コーナー部１０の平面図（製氷皿１挿入初期時（製氷皿１の製氷皿駆動部４側がフリーの状態）））、図１６は図１５のＷ−Ｗ断面図、図１７は製氷コーナー部１０の平面図（製氷皿１挿入中間時（製氷皿１の凸形状部１ａ−４がガイド形状部３ｃに載りはじめた状態））、図１８は図１７のＹ−Ｙ断面図、図１９は製氷コーナー部１０の平面図（製氷皿１挿入直前時（皿部１ａの凸形状部１ａ−４が、ガイド形状部３ｃに沿って持ち上げられ、皿部１ａ後部が製氷皿駆動部４の駆動軸と水平な位置となる状態）、図２０は図１９のＸ−Ｘ断面図、図２１は製氷コーナー部１０の平面図（製氷皿１挿入完了時）、図２２は図２１のＺ−Ｚ断面図である。 15 to 22 are diagrams showing the first embodiment, and FIG. 15 is a plan view of the ice making corner portion 10 (when the ice tray 1 is initially inserted (the ice tray driving portion 4 side of the ice tray 1 is free))). 16 is a cross-sectional view taken along the line W-W in FIG. 15, and FIG. 17 is a plan view of the ice making corner 10 (when the ice tray 1 is in the middle of insertion (the convex shape portion 1a-4 of the ice tray 1 starts to be placed on the guide shape portion 3c). )), FIG. 18 is a YY cross-sectional view of FIG. 17, and FIG. 19 is a plan view of the ice making corner portion 10 (immediately before insertion of the ice tray 1 (the convex shape portion 1a-4 of the plate portion 1a becomes the guide shape portion 3c). FIG. 20 is a cross-sectional view taken along the line XX of FIG. 19, and FIG. 21 is a plan view of the ice making corner portion 10 (a state in which the rear portion of the plate portion 1a is positioned horizontally with the drive shaft of the ice tray driving portion 4). FIG. 22 is a ZZ cross-sectional view of FIG. 21 (when the ice tray 1 is completely inserted).

製氷コーナー部１０は、以上のように構成されるが、本実施の形態における最大の特徴は、製氷皿保持枠体３壁面に皿部１ａの凸形状部１ａ−４が載り上げるガイド形状部３ｃを備え、製氷皿１を製氷皿保持枠体３に挿入時に、皿部１ａの凸形状部１ａ−４が製氷皿保持枠体３壁面のガイド形状部３ｃにより、皿部１ａ後部の凹部１ａ−３（図６参照）が製氷皿駆動部４の駆動軸４ａと水平となる位置まで持ち上げられ、更に製氷皿１を押し込むことで皿部１ａは製氷皿駆動部４の駆動軸４ａと嵌合する点にある。 Although the ice making corner portion 10 is configured as described above, the greatest feature in the present embodiment is that the guide shape portion 3c on which the convex shape portion 1a-4 of the plate portion 1a is placed on the wall surface of the ice making tray holding frame body 3. When the ice tray 1 is inserted into the ice tray holding frame 3, the convex portion 1a-4 of the tray portion 1a is formed by the guide shape portion 3c of the wall surface of the ice tray holding frame 3 so that the concave portion 1a- 3 (see FIG. 6) is lifted to a position that is horizontal with the drive shaft 4a of the ice tray drive unit 4, and the plate portion 1a is fitted with the drive shaft 4a of the ice tray drive unit 4 by pushing the ice tray 1 further. In the point.

上記のように構成することにより、製氷皿挿入用間口形状部３ａからガイド形状部３ｃまでの間、皿部１ａと製氷皿保持枠体３の壁面とのクリアランスを大きめに確保することができる。そのため、製氷皿１（皿部１ａ）−製氷皿保持枠体３の壁面間での氷結や、皿部１ａ回転時の氷はさみ等の品質面の課題を防ぐことが可能となる。 By configuring as described above, a large clearance between the tray portion 1a and the wall surface of the ice tray holding frame body 3 can be secured between the ice tray insertion frontage shape portion 3a and the guide shape portion 3c. Therefore, it is possible to prevent quality problems such as icing between the wall surface of the ice tray 1 (dish portion 1a) and the ice tray holding frame 3 and ice scissors during rotation of the plate portion 1a.

図１５、図１６に示すように、製氷皿１の皿部１ａを、製氷皿保持枠体３の製氷皿挿入用間口形状部３ａの開口部（間口）に挿入し、皿部１ａの凸形状部１ａ−４が製氷皿保持枠体３のガイド形状部３ｃより手前にある状態（挿入初期時）では、ガイド形状部３ｃは製氷皿保持枠体３の一部壁面に存在し、そのガイド形状部３ｃに皿部１ａの凸形状部１ａ−４が載るまでの間は、皿部１ａは上下方向において自由に移動できる状態となる。また、皿部１ａと製氷皿保持枠体３の壁面とのクリアランスを大きめに確保することができる。そのため、製氷皿１（皿部１ａ）−製氷皿保持枠体３の壁面間での氷結や、皿部１ａ回転時における氷はさみ等の品質面の課題を解決することが可能となる。 As shown in FIGS. 15 and 16, the dish part 1 a of the ice tray 1 is inserted into the opening (front edge) of the ice tray insertion front shape part 3 a of the ice tray holding frame 3, and the convex shape of the dish part 1 a is formed. In a state where the portion 1a-4 is in front of the guide shape portion 3c of the ice tray holding frame body 3 (at the time of initial insertion), the guide shape portion 3c exists on a partial wall surface of the ice tray holding frame body 3, and the guide shape thereof Until the convex part 1a-4 of the dish part 1a is placed on the part 3c, the dish part 1a can be freely moved in the vertical direction. In addition, a large clearance between the dish portion 1a and the wall surface of the ice tray holding frame 3 can be secured. Therefore, it is possible to solve quality problems such as icing between the ice tray 1 (dish portion 1a) and the wall surface of the ice tray holding frame 3 and ice scissors during rotation of the plate portion 1a.

しかし、このまま皿部１ａが自由の状態で製氷皿保持枠体３の奥へ進むのでは、皿部１ａを製氷皿駆動部４の駆動軸４ａに嵌めることができない。 However, if the tray portion 1a is moved freely into the ice tray holding frame 3 in a free state, the tray portion 1a cannot be fitted to the drive shaft 4a of the ice tray driving portion 4.

そこで、図１７、図１８に示すように、皿部１ａの挿入が所定の距離進むと、皿部１ａの凸形状部１ａ−４がガイド形状部３ｃに載りはじめる（製氷皿１挿入中間時）。 Therefore, as shown in FIGS. 17 and 18, when the insertion of the plate portion 1a advances by a predetermined distance, the convex portion 1a-4 of the plate portion 1a starts to be placed on the guide shape portion 3c (when the ice tray 1 is being inserted). .

皿部１ａの凸形状部１ａ−４がガイド形状部３ｃに載り、さらに製氷皿１を挿入していくと、皿部１ａの凸形状部１ａ−４がガイド形状８に沿って持ち上げられ、皿部１ａの後部は製氷皿駆動部４の駆動軸４ａと略水平な位置となる（図１９、図２０参照）。 When the convex portion 1a-4 of the dish portion 1a is placed on the guide shape portion 3c and the ice tray 1 is further inserted, the convex portion 1a-4 of the dish portion 1a is lifted along the guide shape 8, The rear part of the part 1a is positioned substantially horizontal with the drive shaft 4a of the ice tray drive part 4 (see FIGS. 19 and 20).

さらに製氷皿１を製氷皿保持枠体３の奥へ押し込むことにより、製氷皿駆動部４の駆動軸４ａが皿部１ａ後部の凹部１ａ−３と嵌合し、このときハンドル部１ｂも製氷皿保持枠体３の製氷皿挿入用間口形状部３ａと嵌合し、製氷皿１の製氷皿保持枠体３への挿入が完了する（図２１、図２２参照）。 Further, by pushing the ice tray 1 into the depth of the ice tray holding frame 3, the drive shaft 4a of the ice tray drive unit 4 is fitted into the recess 1a-3 at the rear of the plate portion 1a, and at this time, the handle portion 1b is also connected to the ice tray. The ice tray 1 is fitted into the ice tray insertion frontage shape portion 3a of the holding frame 3, and the insertion of the ice tray 1 into the ice tray holding frame 3 is completed (see FIGS. 21 and 22).

このように、製氷皿保持枠体３の一部壁面にのみガイド形状部３ｃが存在しているため、ガイド形状部３ｃの存在しない領域においては、製氷皿保持枠体３の壁面と皿部１ａとのクリアランスを十分にとることができる。また、製氷皿保持枠体３のガイド形状部３ｃの冷蔵庫（製氷室）奥行き方向の寸法を小さくしていくことにより、クリアランスが十分な領域は拡大していき、氷結および氷はさみの危険を防止することが可能となる。 Thus, since the guide shape part 3c exists only in the partial wall surface of the ice tray holding frame 3, in the area | region where the guide shape part 3c does not exist, the wall surface of the ice tray holding frame 3 and the plate part 1a. And sufficient clearance. Further, by reducing the size of the guide-shaped portion 3c of the ice tray holding frame 3 in the depth direction of the refrigerator (ice-making chamber), the area with sufficient clearance is expanded and the risk of freezing and ice scissors is prevented. It becomes possible to do.

また、上記特許文献１に開示されているように、製氷皿保持枠体のレール形状に載る部品を別途製氷皿全周に渡り用意することで、製氷皿と周囲壁面とのクリアランスを確保することは可能であるが、そのためには新たに大きな部品を追加する必要があるためにコストアップとなる。 In addition, as disclosed in the above-mentioned Patent Document 1, the clearance between the ice tray and the surrounding wall surface is ensured by separately preparing parts mounted on the rail shape of the ice tray holding frame over the entire circumference of the ice tray. Although it is possible to do so, it is necessary to add a new large part, which increases the cost.

それに対し、図２に示すように製氷皿１を凸形状部１ａ−４つきの皿部１ａとハンドル部１ｂとで構成することで同一の機能を実現することができ、かつそれに係るコストは最小となる。 On the other hand, as shown in FIG. 2, the same function can be realized by configuring the ice tray 1 with the tray portion 1a with the convex portion 1a-4 and the handle portion 1b, and the cost associated with it is minimized.
