Description

本発明は、製氷器に関し、特に透明氷が作成可能で、氷を作る型と断熱容器が外しやすい製氷器に関する。 TECHNICAL FIELD The present invention relates to an ice maker, and more particularly to an ice maker capable of making transparent ice and having an easy-to-remove ice making mold and heat insulating container.

透明な氷を作成する製氷器として、内部に多面体や球形等の空間を有するとともに、上下に水が移動可能な孔を設けた、上下2分割の型と断熱容器を用いる構造の製氷器が知られている(特許文献1、特許文献2)。この製氷器は、型を断熱容器に挿入後、型上部の孔から水を注入、冷蔵庫の製氷室に入れ、内部の水を上方からゆっくり凍らせながら、水に含まれる不純物を型下部の孔から断熱容器に移動させ、完全に凍った後、型と断熱容器を分離させ、型を開くことにより、透明な氷を取り出すものである。 As an ice maker for making transparent ice, there is known an ice maker that has a space such as a polyhedron or a sphere inside and a hole that allows water to move up and down. (Patent Document 1, Patent Document 2). After inserting the mold into an insulated container, water is poured into the ice making chamber of the refrigerator from the top of the mold, and the impurities in the water are removed from the bottom of the mold while the water is slowly frozen from above. After the ice is completely frozen, the mold is separated from the heat-insulating container, and the mold is opened to take out transparent ice.

ところで、水は氷になると、約10%の体積膨張が発生する。水を注入した型上部の孔付近が先に凍るので、型上部の孔から水や氷が出ることは殆どない。その結果、型が上下に分割されていることにより、大きな継ぎ目のある氷が出来やすく、また型が内部から膨張することにより断熱容器に押し付けられてしまい、型の分離がしにくくなるという問題が発生する。 By the way, when water turns into ice, its volume expands by about 10%. Since the area around the hole in the upper part of the mold where water is injected freezes first, almost no water or ice comes out of the hole in the upper part of the mold. As a result, because the mold is divided into upper and lower parts, it is easy to create ice with a large seam, and the mold expands from the inside, pushing it against the insulated container, making it difficult to separate the mold. Occur.

前記上端部に前記空間部と外部を連通する注水孔を有し、
前記下端部に前記空間部と外部を連通する不純物移動孔を有していることを特徴とする製氷器である。
In order to solve the above problems, the present invention
a mold that can be divided into at least two along a vertical cross-section and has a space inside that defines the shape of the ice;
a heat insulating container having an opening at its upper end, into which the mold can be inserted and accommodated;
The mold has a lower end on the side to be inserted into the insulated container, and an upper end on the opposite side of the lower end. has a holding portion that is not stored in the heat insulating container formed in
Having a water injection hole in the upper end portion that communicates the space portion with the outside,
The ice maker is characterized in that the lower end portion has an impurity transfer hole that communicates the space portion with the outside.

上記製氷器において、前記型と前記断熱容器の横断面の形状が円であって良い。 In the above ice maker, the cross-sectional shape of the mold and the heat insulating container may be circular.

上記製氷器において、前記型の外周面に、前記上端部側で周長が大きくなるようなテーパーが設けられていて良い。 In the above ice maker, the outer peripheral surface of the mold may be tapered such that the peripheral length increases on the upper end side.

上記製氷器において、前記型を前記断熱容器に収納したとき、前記型の外側面と前記断熱容器の内側面が少なくとも一部で密接する態様であって良い。 In the above ice maker, when the mold is accommodated in the heat insulating container, the outer surface of the mold and the inner surface of the heat insulating container may be at least partially in close contact with each other.

An ice maker is obtained in which the mold can be easily separated from the insulated container using the formed holding portion.

以下、本発明の実施の形態を、図面を参照しながら詳細に説明する。なお本発明は以下に説明する実施形態に限定されるものではない。また以下に示す実施形態では、発明を実施するために技術的に好ましい限定がなされているが、この限定は本発明の必須要件ではない。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiments described below. Also, in the embodiments shown below, technically preferable limitations are made for carrying out the invention, but these limitations are not essential requirements of the invention.

図1は、本発明の製氷器の型の一形態の型片の斜視図である。また図2は側面図である。また図3は線分AA´の部位での横断面図である。また図4は2つの型片を組み合わせたときの横断面の模式図である。本実施形態の型1は、垂直方向、すなわち後述する断熱容器に収納したときの縦方向、に延びる断面で2分割可能とされている。図1は分割した型片1aを縦断面側から見たものである。なお型の分割は2分割に限られず、3分割されるようにしても良い。 FIG. 1 is a perspective view of a mold piece of one embodiment of the ice maker mold of the present invention. 2 is a side view. Also, FIG. 3 is a cross-sectional view at the portion of the line segment AA'. FIG. 4 is a schematic diagram of a cross section when two mold pieces are combined. The mold 1 of the present embodiment can be divided into two by a cross section extending in the vertical direction, that is, the vertical direction when housed in a heat insulating container, which will be described later. FIG. 1 shows the divided mold pieces 1a as seen from the longitudinal section side. Note that the division of the mold is not limited to two divisions, and may be three divisions.

本発明の型はゴム、合成樹脂などの強度と成形性の良い材料を、モールド成形その他の公知の成形法により成形して形成される。中でもシリコーンゴムは断熱性が高く凍結が徐々に進むため、透明な氷が出来やすく好ましい。なお以下では型全体と分割された型片を、特に区別せず「型」と称することがある。 The mold of the present invention is formed by molding a material having good strength and moldability, such as rubber or synthetic resin, by molding or other known molding methods. Among them, silicone rubber is preferable because it has high heat insulating properties and freezes gradually, so that transparent ice can be easily formed. In the following description, the entire mold and the divided mold pieces may be referred to as "mold" without distinction.

型1は、水を収納して所望の形状の氷を形成するために空間部2を内部に有しており、本実施形態の空間部2は球形である。従って型片1aの内部には半球状の空間部2が形成されている。また型片1aの横断面は典型的には図3に示すように半円形であり、型片1aと型片1bを組み合わせた型1の横断面は典型的には図4に示すように円形である。 The mold 1 has a space 2 therein for accommodating water and forming ice of a desired shape, and the space 2 in this embodiment is spherical. Accordingly, a hemispherical space 2 is formed inside the mold piece 1a. The cross section of the mold piece 1a is typically semicircular as shown in FIG. 3, and the cross section of the mold 1 combining the mold pieces 1a and 1b is typically circular as shown in FIG. is.

また空間部2の形状は球形に限られず、型抜きしやすい形状であれば立方体、8面体、32面体(サッカーボール状)などの多面体や、円柱、楕円体、星形、ドーナツ状、あるいはこれらを組み合わせた形状などの任意の立体形状とすることができる。型抜きが可能な形状であれば動物や各種のキャラクターなどの形状も適用可能である。 The shape of the space 2 is not limited to a sphere, and any shape that is easy to die-cut can be a polyhedron such as a cube, an octahedron, or a 32-hedron (like a soccer ball), a cylinder, an ellipsoid, a star, a doughnut, or any of these. can be an arbitrary three-dimensional shape such as a shape in which Shapes such as animals and various characters can also be applied as long as they can be die-cut.

型の上端部、すなわち図2での上側となる部分は、ほぼ平坦であり、反対側の下端部は
半球状をなしている。上端部には、型片を組み合わせたときに空間部2に水を注入するための注水孔3を形成する切り欠き3aが形成され、下端部には水の凍結が進行する際に水に含まれる不純物や泡などを排出するための不純物移動孔4を形成する切り欠き4aが形成され、それぞれ空間部2と型の外部とを連通可能としている。組み合わされる2つの型は、同一の方向から見たときにはほぼ同一の形状である。
The upper end of the mold, ie the upper side in FIG. 2, is substantially flat and the opposite lower end is hemispherical. A notch 3a is formed at the upper end to form a water injection hole 3 for injecting water into the space 2 when the mold pieces are combined, and a cutout 3a is formed at the lower end to contain water when the water freezes. A notch 4a is formed to form an impurity transfer hole 4 for discharging impurities, bubbles, and the like, which are contained in the mold. The two molds to be combined have substantially the same shape when viewed from the same direction.

空間部2の周縁を取り巻くように、2つの型を組み合わせたときに互いに嵌め合いとなるように、縦断面から突出した稜部7aと陥没した溝部7bが形成されている。また同様に互いに嵌め合いとなるように凸部8aと凹部8bが形成されている。これらにより2つの型を組み合わせたときにしっかりと一体化され、2つの型が互いにずれることがなく、また外れにくくもなるので、作成される氷に継ぎ目や段差ができにくくなり、良好な形状の氷(ここでは球形)を作成することができる。 A ridge portion 7a protruding from the longitudinal section and a recessed groove portion 7b are formed so as to surround the peripheral edge of the space portion 2 so as to be fitted to each other when the two molds are combined. Similarly, a convex portion 8a and a concave portion 8b are formed so as to be fitted to each other. As a result, when the two molds are combined, they are firmly integrated, and the two molds do not shift from each other, and they are also less likely to come off. Ice (here spherical) can be created.

上端部はほぼ平坦であるが、注水孔3の周囲は、漏斗状の窪み6が形成されている。注水孔3から水を注ぎ入れるときに、水が外側に流れ落ちずに窪み6から注水孔3に集まるようにすることができる。 The upper end is almost flat, but a funnel-shaped depression 6 is formed around the water injection hole 3 . When pouring water from the water injection hole 3, the water can be gathered in the water injection hole 3 from the recess 6 without flowing down to the outside.

上端部の上端周縁からは、保持部5がフランジ状に外側に張り出すように形成され、その外縁が後述する断熱容器の開口部よりも外側にはみ出す様に形成されている。本実施形態におけるように型1の横断面が円形であれば、保持部の外形は典型的には円形であり、型の側壁面9から張り出した円盤状の形状である。保持部5が形成されていることにより、型1を後述する断熱容器に収納して氷を作成した後に断熱容器から取り出す際に、保持部5を掴んで型1を取り出すことができる。 A holding portion 5 is formed so as to protrude outward in a flange shape from the upper end peripheral edge of the upper end portion, and the outer edge thereof is formed so as to protrude outside an opening of a heat insulating container, which will be described later. If the cross section of the mold 1 is circular as in the present embodiment, the outer shape of the holding portion is typically circular and has a disk-like shape protruding from the side wall surface 9 of the mold. Since the holding part 5 is formed, the holding part 5 can be grasped and the mold 1 can be taken out when the mold 1 is stored in an insulated container to be described later to make ice and then taken out from the insulated container.

また型1の横断面が円形であれば、保持部5を保持して型1を捩じって回転させるようにして断熱容器から取り出すことができるため、取出しがより容易である。保持部の外形は円形以外にも、多角形状とすることもできる。多角形状とすると捩じる際の引っ掛かりができるため、型1がより取り出しやすい。 Further, if the cross section of the mold 1 is circular, the mold 1 can be taken out from the heat-insulating container by holding the holding portion 5 and twisting the mold 1 so as to rotate. The outer shape of the holding portion may be polygonal instead of circular. The polygonal shape can be caught when twisted, so that the mold 1 can be taken out more easily.

図5は本発明の製氷器の断熱容器の一形態の側方断面図である。断熱容器10は上部の開口部13から型1を挿入して、内部に収納することができるコップ状の容器である。断熱容器10は断熱性を有する素材、例えば発泡スチロール、発泡プラスチック、発泡パルプ、コルク、フェルト、ガラス繊維、木材などの熱伝導性の低い素材を単独で、または組み合わせて形成することができるが、熱伝導性の低い素材であって型を分離する際にしっかりと掴むことができる強度を有していれば特に制限はない。 FIG. 5 is a side sectional view of one form of the heat insulating container of the ice maker of the present invention. The adiabatic container 10 is a cup-shaped container in which the mold 1 can be inserted through an opening 13 at the top and stored therein. The heat-insulating container 10 can be made of a material having heat insulation properties, such as polystyrene foam, foamed plastic, foamed pulp, cork, felt, glass fiber, wood, or any other material with low thermal conductivity, either alone or in combination. There is no particular limitation as long as the material has low conductivity and is strong enough to be firmly grasped when separating the molds.

またこれ以外の構成としても良く、例えば図10に示す例は、金属製の外壁11と内壁12の間に空間を設けた二重容器として、間の空間を真空状態として断熱性の容器としたものである。底面に外壁11と内壁12の間の空間を気密に保つ栓14が設けられている。 Other configurations may also be used. For example, the example shown in FIG. 10 is a double container in which a space is provided between the outer wall 11 and the inner wall 12 made of metal, and the space between them is evacuated to form a heat insulating container. It is. A plug 14 is provided on the bottom surface to keep the space between the outer wall 11 and the inner wall 12 airtight.

本実施形態の製氷器を用いて球状の氷を作成する手順を説明する。
まず、断熱容器10に半分程度の水15を入れ、型1を開口部から挿入してセットする(図6)。このとき、型1の下端部の不純物移動孔4から水15が空間部2に入ってくるが、特に差支えはない。
A procedure for making spherical ice using the ice maker of this embodiment will be described.
First, about half of the water 15 is put into the heat insulating container 10, and the mold 1 is inserted through the opening and set (FIG. 6). At this time, water 15 enters the space 2 from the impurity transfer hole 4 at the lower end of the mold 1, but there is no particular problem.

次いで、注水孔3から、空間部2が水で満たされるまで水15を注入する(図7)。
水を満たした製氷器を冷凍庫に入れる。冷凍時間は例えば10数時間程度である。すると水15は冷凍庫の冷気が直接当たる上端部側から徐々に凍結して氷となり、断熱容器10に覆われた下端部側は凍結が遅くなる。その過程で、水15に含まれた不純物や空気が徐
々に凍結していない水の部分に移行してゆくことで、下端部の不純物移動孔4から型1の外部に押し出されるため、空間部2に透明な球状の氷16が作成できる。
Next, water 15 is injected from the water injection hole 3 until the space 2 is filled with water (FIG. 7).
Place the ice maker filled with water in the freezer. The freezing time is, for example, about 10 hours. As a result, the water 15 gradually freezes into ice from the upper end of the freezer, which is directly exposed to the cold air, while the lower end covered with the heat-insulating container 10 freezes slowly. In the process, the impurities and air contained in the water 15 gradually migrate to the unfrozen portion of the water, and are pushed out of the mold 1 through the impurity transfer holes 4 at the lower end. 2, transparent spherical ice 16 can be created.

このとき、型1の外側面と断熱容器10の内側面が、少なくともその一部で密接されるような形状とすると、追加して注入した水が密接した部分でせき止められて開口部側に上がって来てあふれるようなことがなく、また冷凍庫に入れたときに冷気が型1の下端部側に侵入せず、上端部側からの凍結が好適に進行するため好ましい。また型が垂直方向に分割されているため、凍結に伴い氷の体積が膨張しても断熱容器10で規制されて型片が離れ難く、継ぎ目などができにくい。 At this time, if the outer surface of the mold 1 and the inner surface of the heat insulating container 10 are shaped so that they are in close contact with each other at least in part, the additionally injected water will be dammed up at the close contact and rise to the opening side. It is preferable because it does not come out and overflow, and cold air does not enter the lower end side of the mold 1 when it is put in the freezer, and the freezing from the upper end side progresses favorably. In addition, since the mold is vertically divided, even if the volume of the ice expands due to freezing, the mold pieces are restrained by the heat insulating container 10, and the mold pieces are difficult to separate and seams are less likely to occur.

空間部2の水が完全に凍結した後、さらに断熱容器10の底部側の水が凍結してゆくと、体積が膨張することで型1が開口部側に押し上げられることがあるが、空間部2の水はこのときほとんど氷になっているので継ぎ目ができるなどといった影響は少ない。逆に、保持部5が断熱容器の開口部の縁から持ち上げられた態様となり、型1を分離しやすくなることがある。 After the water in the space 2 is completely frozen, when the water on the bottom side of the heat-insulating container 10 freezes further, the mold 1 may be pushed up toward the opening side due to the expansion of the volume. Since the water in 2 is almost frozen at this time, there is little effect such as the formation of seams. Conversely, the holding part 5 may be lifted from the edge of the opening of the heat-insulating container, making it easier to separate the mold 1 .

型内部の水が完全に凍結したら製氷器を冷凍庫から取り出し、型1を断熱容器10から取り出して分離する。このとき型1の外側の、断熱容器10の底部側の水は完全には凍結していなくても良い。分離の際、断熱容器10の開口部13よりも外側に張り出して持ちやすくなっている保持部5を持って容易に取り出すことができ、さらに型1の横断面が円形であれば、左右に捩じることができて型1がより分離しやすくなる(図8)。 When the water inside the mold is completely frozen, the ice maker is removed from the freezer, and the mold 1 is removed from the heat insulating container 10 and separated. At this time, the water on the bottom side of the heat insulating container 10 outside the mold 1 may not be completely frozen. At the time of separation, it can be easily taken out by holding the holding part 5 which protrudes outward from the opening part 13 of the heat insulating container 10 and is easy to hold. It can be twisted and the mold 1 can be separated more easily (Fig. 8).

取り出した型1から、一方の型片を取り外すと、図9に示す様に球形の氷16が現れる。このとき、不純物移動孔4の部分の氷が余分に形成されているが、微小で単純な形状であるので容易に削り落とすことができる。断熱容器10に残った氷または水は廃棄される。以上の様にして、透明で球形の氷16が得られる。空間部2の形状が球形以外の場合であっても、手順は基本的に同一である。 When one mold piece is removed from the mold 1 taken out, spherical ice 16 appears as shown in FIG. At this time, excess ice is formed in the portion of the impurity transfer hole 4, but it can be easily scraped off because of its minute and simple shape. Any ice or water remaining in the insulated container 10 is discarded. As described above, transparent spherical ice 16 is obtained. The procedure is basically the same even if the shape of the space 2 is not spherical.

本発明は以上説明した実施形態に限定されるものではなく、発明の趣旨を逸脱しない限りにおいて変更を加えることが可能である。図10は、本発明の製氷器において、型を別形態としたときの、型を取り出す態様の説明図である。本実施形態の型20は、側壁面9が上端部側で周長が大きくなるようにテーパーが設けられている。 The present invention is not limited to the embodiments described above, and modifications can be made without departing from the gist of the invention. 10A and 10B are explanatory diagrams of a mode of taking out the mold when the mold is in another form in the ice maker of the present invention. The mold 20 of the present embodiment is tapered such that the side wall surface 9 has a larger peripheral length on the upper end side.

このような形状とすると、冷凍庫での製氷の際に、凍結が進んで型20の外側の断熱容器10内の水15が凍結することで、前述のように体積が膨張した氷16となり、型20を開口部側に押し上げる(点線で示す型20)。するとテーパーのある側壁面の部位9´では、型20が断熱容器10の内壁12から自然に分離される。その結果、型20を断熱容器10から分離して取り出すのがより容易に行えるという効果が得られる。このとき、型20のテーパーの形状に合わせて断熱容器の内壁12にもテーパーを設けても良い。 With such a shape, when the ice is made in the freezer, the water 15 in the heat insulating container 10 outside the mold 20 freezes, and the ice 16 expands in volume as described above. 20 is pushed up toward the opening (mold 20 indicated by dotted line). The mold 20 is then naturally separated from the inner wall 12 of the insulated container 10 at the tapered side wall portion 9'. As a result, it is possible to obtain the effect that the mold 20 can be separated from the heat insulating container 10 and taken out more easily. At this time, the inner wall 12 of the heat insulating container may also be tapered in accordance with the tapered shape of the mold 20 .

以上説明したように、本発明の製氷器によれば、継ぎ目の目立たない所望の形状の氷が作成でき、また製氷用の型を断熱容器から取り出すのが容易な製氷器が得られる。 As described above, according to the ice maker of the present invention, it is possible to make ice of a desired shape with inconspicuous seams and to easily take out the ice making mold from the heat insulating container.
