Description

この発明は、蒸発管が配設された製氷基板と、該製氷基板に配設され、製氷小室を画成する仕切部材とから構成される自動製氷機の製氷部に関するものである。   The present invention relates to an ice making part of an automatic ice making machine which is composed of an ice making substrate on which an evaporation tube is disposed and a partition member which is disposed on the ice making substrate and defines an ice making chamber.

例えば、喫茶店等の飲食店で使用される角形の氷を連続的に製造する自動製氷機として、下向きに開口する多数の製氷小室内で製氷水の氷結を行う噴射式の自動製氷機が知られている。この自動製氷機の概略構成を説明すれば、製氷機本体をなす筐体の所定位置に、下方に開口する多数の製氷小室が画成された製氷部が配設されると共に、該製氷部の下方には、所定間隔離間して製氷水タンクが配置される。この製氷水タンクから製氷水が散水パイプに供給されて、該散水パイプに開設された噴射孔を介して製氷部の各製氷小室へ向けて製氷水が下方から噴射供給される。また、前記製氷部の上面には、冷凍系から導出する蒸発管が蛇行配置され、製氷時において、該蒸発管へ冷媒を供給することで、製氷部が冷却されるようになっている。前記散水パイプから噴射された製氷水は、冷媒により冷却された製氷小室に接触して冷却され、該製氷小室内に氷が形成されるようになっている(特許文献１参照)。   For example, as an automatic ice maker that continuously manufactures square ice used in restaurants such as coffee shops, there is a jet type automatic ice maker that freezes ice-making water in a number of ice-making chambers that open downward. ing. Describing the schematic configuration of this automatic ice maker, an ice making part in which a large number of ice making chambers opening downwards are arranged at predetermined positions of the housing forming the ice making machine body, and the ice making part Below, an ice making water tank is arranged at a predetermined interval. Ice making water is supplied from the ice making water tank to the water sprinkling pipe, and ice making water is jetted and supplied from below to each ice making small chamber of the ice making unit through the injection hole provided in the water sprinkling pipe. Further, on the upper surface of the ice making section, an evaporation pipe led out from the refrigeration system is meanderingly arranged, and at the time of ice making, the ice making section is cooled by supplying a refrigerant to the evaporation pipe. The ice making water sprayed from the sprinkling pipe comes into contact with the ice making chamber cooled by the refrigerant and is cooled, and ice is formed in the ice making chamber (see Patent Document 1).

図９は、このような噴射式の自動製氷機に配設される従来の製氷部１０を示す分解斜視図であって、上面１２に蒸発管１４が配設された矩形状の製氷基板１６と、該製氷基板１６の下面(図示せず)に配設され、複数の製氷小室(図示せず)を画成する仕切部材２２とから基本的に構成されている。なお、製氷基板１６の周縁部から側壁部２４が下方へ延出しており、製氷基板１６および側壁部２４により下方に開放する製氷室２６を構成している。前記仕切部材２２は、短尺な仕切板２８(以下、横方向仕切板という場合がある)と、長尺な仕切板３０(以下、縦方向仕切板という)とを縦横格子状に組付けて構成され、これら仕切板２８,３０により直方体状の製氷小室が画成される。   FIG. 9 is an exploded perspective view showing a conventional ice making unit 10 provided in such an injection type automatic ice making machine, and includes a rectangular ice making substrate 16 having an upper surface 12 and an evaporation tube 14 disposed thereon. The partition member 22 is basically composed of a partition member 22 disposed on the lower surface (not shown) of the ice making substrate 16 and defining a plurality of ice making chambers (not shown). The side wall 24 extends downward from the peripheral edge of the ice making substrate 16, and the ice making chamber 26 that opens downward is constituted by the ice making substrate 16 and the side wall 24. The partition member 22 is configured by assembling a short partition plate 28 (hereinafter also referred to as a horizontal partition plate) and a long partition plate 30 (hereinafter referred to as a vertical partition plate) in a vertical and horizontal lattice pattern. These partition plates 28 and 30 define a rectangular parallelepiped ice making chamber.

前記横方向仕切板２８には、下方に開放する下向きスリット３２が所定間隔離間して複数形成されている。また、縦方向仕切板３０には、下向きスリット３２に対応して、上方に開放する上向きスリット３４が複数形成されている。そして、下向きスリット３２および上向きスリット３４を互いに係合させることで、横方向仕切板２８および縦方向仕切板３０が組付けられるようになっている。前記横方向仕切板２８および縦方向仕切板３０の上端縁部には、夫々、立方体状の固定突起３６が上方に向けて複数突設されている。各固定突起３６の断面形状は、図１０に示すように、一辺が仕切板２８,３０(図１０には、横方向仕切板２８を図示)の板厚に等しい寸法の正方形をなしている。また、固定突起３６の突出量は、前記製氷基板１６の板厚よりも大きく設定されている。   A plurality of downward slits 32 opened downward are formed in the horizontal partition plate 28 at a predetermined interval. The vertical partition plate 30 is formed with a plurality of upward slits 34 corresponding to the downward slits 32 that open upward. And the horizontal direction partition plate 28 and the vertical direction partition plate 30 are assembled | attached by engaging the downward slit 32 and the upward slit 34 mutually. A plurality of cube-shaped fixing projections 36 project upward from the upper end edges of the horizontal partition plate 28 and the vertical partition plate 30. As shown in FIG. 10, the cross-sectional shape of each fixing projection 36 is a square having a dimension equal to the plate thickness of the partition plates 28 and 30 (the lateral partition plate 28 is shown in FIG. 10). Further, the protruding amount of the fixed protrusion 36 is set larger than the thickness of the ice making substrate 16.

前記製氷基板１６には、前記固定突起３６に対応して複数の固定孔３８が開設されている。この固定孔３８は、図１０に示すように、固定突起３６の断面積より大きな面積の円形状をなしている。そして、前記固定突起３６を固定孔３８に挿通させて、前記製氷基板１６の上面１２に突出した固定突起３６の端部をハンマー等で圧潰することで、固定突起３６が固定孔３８に係合し、仕切部材２２(仕切板２８,３０)が製氷基板１６に固定される。   The ice making substrate 16 has a plurality of fixing holes 38 corresponding to the fixing protrusions 36. As shown in FIG. 10, the fixing hole 38 has a circular shape with an area larger than the cross-sectional area of the fixing protrusion 36. Then, the fixing protrusion 36 is inserted into the fixing hole 38 and the end of the fixing protrusion 36 protruding from the upper surface 12 of the ice making substrate 16 is crushed with a hammer or the like, so that the fixing protrusion 36 is engaged with the fixing hole 38. The partition member 22 (partition plates 28 and 30) is fixed to the ice making substrate 16.

特開２００６−１１８８１６号公報JP 2006-118816 A

ここで、前記固定突起３６の端部は、ハンマー等で圧潰された際に、固定孔３８内で僅かに拡がった状態となる。しかしながら、図１０に示すように、固定孔３８は、固定突起３６で完全に閉塞されることはなく、該固定突起３６の端部と固定孔３８の縁部との間に隙間が生じてしまう。このような隙間が生じると、固定突起３６の固定孔３８に対する係合力が弱くなり、製氷基板１６と仕切部材２２との固定強度が不十分になる難点があった。その結果、仕切部材２２が製氷基板１６に対してガタついたり、仕切部材２２の一部または全体が製氷基板１６から外れてしまうことがあった。   Here, the end portion of the fixing protrusion 36 is slightly expanded in the fixing hole 38 when crushed by a hammer or the like. However, as shown in FIG. 10, the fixing hole 38 is not completely closed by the fixing protrusion 36, and a gap is generated between the end of the fixing protrusion 36 and the edge of the fixing hole 38. . When such a gap is generated, the engaging force of the fixing protrusion 36 with respect to the fixing hole 38 becomes weak, and there is a problem that the fixing strength between the ice making substrate 16 and the partition member 22 becomes insufficient. As a result, the partition member 22 may rattle with respect to the ice making substrate 16 or a part or the whole of the partition member 22 may be detached from the ice making substrate 16.

また、製氷部１０の製造過程においては、製氷基板１６に仕切部材２２を取付けた後、製氷部１０の表面全体に錫によるめっき処理が行われる。ところが、このめっき処理時に、前述した固定突起３６と固定孔３８との隙間に錫が溜まり、当該錫がそのまま固着することがあった。めっき処理に用いられる錫は、製氷部１０を構成する銅等の金属に較べ強度が弱く、製氷−除氷サイクルの温度差により製氷部１０に応力が加わった際に、隙間に溜った錫が起点となって錫めっきが剥離したり、製氷部１０が変形・破損したりすることがあった。また、固定突起３６と固定孔３８との隙間には、自動製氷機の運転時に水が溜まり易く、隙間に溜った水が凍結・融解を繰り返すことで体積変動を来たし、錫めっきがより剥離し易くなる難点があった。   In addition, in the manufacturing process of the ice making unit 10, after the partition member 22 is attached to the ice making substrate 16, the entire surface of the ice making unit 10 is plated with tin. However, during this plating process, tin may accumulate in the gap between the fixing protrusion 36 and the fixing hole 38 described above, and the tin may adhere as it is. The tin used for the plating process is weaker than metals such as copper constituting the ice making part 10, and when the stress is applied to the ice making part 10 due to the temperature difference between the ice making and deicing cycles, the tin accumulated in the gap As a starting point, the tin plating may peel off, or the ice making part 10 may be deformed or damaged. In addition, in the gap between the fixed projection 36 and the fixed hole 38, water easily collects during the operation of the automatic ice making machine, and the volume of the water accumulated in the gap is repeatedly frozen and thawed, and the tin plating further peels off. There was a difficulty that made it easier.

そこで、本発明は、前述した従来の技術に内在している前記課題に鑑み、これを好適に解決するべく提案されたものであって、仕切部材を製氷基板に強固に固定し得ると共に、固定突起と固定孔との間に隙間が殆ど生じることのない自動製氷機の製氷部を提供することを目的とする。   Accordingly, the present invention has been proposed to solve this problem in view of the above-mentioned problems inherent in the above-described conventional technology, and the partition member can be firmly fixed to the ice making substrate and fixed. An object of the present invention is to provide an ice making part of an automatic ice making machine in which a gap is hardly generated between the protrusion and the fixing hole.

前述した課題を解決し、所期の目的を好適に達成するため、本願の請求項１に係る発明の自動製氷機の製氷部は、
一方の面に蒸発管が配設された製氷基板と、前記製氷基板の他方の面に配設され、製氷小室を画成する仕切部材とからなる自動製氷機の製氷部において、

In addition, since the retaining portion closes the expanded portion, there is almost no gap between the fixing protrusion and the fixing hole, and it is possible to suppress the accumulation of tin during plating and water during operation in the gap. obtain. Further, since the fixing hole is composed of the reduced diameter portion and the expanded portion, the retaining portion cannot pass through the reduced diameter portion, and the retaining of the fixing protrusion with respect to the fixing hole is reliably achieved.

前記製氷基板１６には、上下方向に開放する長孔状の固定孔４４が仕切板２８,３０の固定突起４２に対応して複数穿設されており、各固定孔４４に固定突起４２が製氷基板１６の下面１８側から挿通されるようになっている。図１に示すように、横方向仕切板２８の固定突起４２に対応する固定孔４４は、製氷基板１６の短手方向に長手方向が延在するよう設けられ、また、縦方向仕切板３０の固定突起４２に対応する固定孔４４は、製氷基板１６の長手方向に長手方向が延在するよう設けられる。各固定孔４４は、図２(ｂ),(ｃ)に示すように、製氷基板１６の下面(他方の面)１８側に位置する縮径部４６と、製氷基板１６の上面(一方の面)１２側に位置する拡開部４８とから構成されている。   The ice making substrate 16 is provided with a plurality of elongated fixing holes 44 that open in the vertical direction, corresponding to the fixing protrusions 42 of the partition plates 28 and 30, and the fixing protrusions 42 are formed in each fixing hole 44. It is inserted from the lower surface 18 side of the substrate 16. As shown in FIG. 1, the fixing holes 44 corresponding to the fixing protrusions 42 of the lateral partition plate 28 are provided so that the longitudinal direction extends in the short direction of the ice making substrate 16. The fixing hole 44 corresponding to the fixing protrusion 42 is provided so that the longitudinal direction extends in the longitudinal direction of the ice making substrate 16. As shown in FIGS. 2B and 2C, each fixing hole 44 includes a reduced diameter portion 46 positioned on the lower surface (the other surface) 18 side of the ice making substrate 16 and an upper surface (one surface) of the ice making substrate 16. ) It is comprised from the expansion part 48 located in the 12 side.

前記縮径部４６は、製氷基板１６に対し上下方向に同一の開口面積で穿設されており、図２(ａ)に示すように、縮径部４６の開口形状は、対応する固定突起４２の長手方向に長尺な長円形状をなしている。縮径部４６の短手方向の寸法は、前記固定突起４２の短手方向の寸法に略一致すると共に、縮径部４６の長手方向の寸法は、固定突起４２の長手方向の寸法より長尺に設定されている。すなわち、縮径部４６に固定突起４２を挿通させた際に、該縮径部４６の長手方向の縁部が固定突起４２の長手方向の側面に当接すると共に、縮径部４６の短手方向の縁部と固定突起４２の短手方向の側面との間に狭小なスペースＳ1が画成されるようになっている。 The diameter-reduced portion 46 is formed in the vertical direction with respect to the ice making substrate 16 with the same opening area. As shown in FIG. 2A, the opening shape of the diameter-reduced portion 46 has a corresponding fixed protrusion 42. It has a long oval shape in the longitudinal direction. The size in the short direction of the reduced diameter portion 46 substantially matches the size in the short direction of the fixed projection 42, and the length in the longitudinal direction of the reduced diameter portion 46 is longer than the size in the longitudinal direction of the fixed projection 42. Is set to That is, when the fixed protrusion 42 is inserted into the reduced diameter portion 46, the longitudinal edge of the reduced diameter portion 46 abuts on the side surface in the longitudinal direction of the fixed protrusion 42, and the shorter direction of the reduced diameter portion 46. A narrow space S 1 is defined between the edge of the fixing projection 42 and the side surface of the fixing projection 42 in the short direction.

前記拡開部４８は、前記縮径部４６の上縁部に連設されて、該縮径部４６より大きな開口面積を有している。拡開部４８は、製氷基板１６の下面１８から上面１２(すなわち、上方)へ向かうにつれて次第に開口面積が拡がるように付されたテーパ５０により構成されており、図２(ａ)に示すように、拡開部４８の製氷基板１６の上面１２における開口形状は、前記縮径部４６を一回り大きくした長円形状をなしている。また、前記テーパ５０は、縮径部４６の上縁部から製氷基板１６の上面１２に向けて直線的な傾斜面をなしている。   The expanded portion 48 is connected to the upper edge portion of the reduced diameter portion 46 and has a larger opening area than the reduced diameter portion 46. The expanding portion 48 is constituted by a taper 50 attached so that the opening area gradually increases from the lower surface 18 of the ice making substrate 16 toward the upper surface 12 (that is, upward), as shown in FIG. The opening shape of the expanded portion 48 in the upper surface 12 of the ice making substrate 16 is an oval shape that is slightly larger than the reduced diameter portion 46. Further, the taper 50 forms a linear inclined surface from the upper edge portion of the reduced diameter portion 46 toward the upper surface 12 of the ice making substrate 16.

前記固定突起４２の端部側は、前記固定孔４４を介して製氷基板１６の上面１２から突出する端部がハンマー等で圧潰されることで形成される抜止め部５２で構成されている。図３(ａ)〜(ｃ)に示すように、この抜止め部５２の上面は、前記製氷基板１６の上面１２と略同一面を形成すると共に、抜止め部５２の上面は、固定突起４２の本体部４２ａ(縮径部４６に位置する部分)の断面形状より一回り大きな形状をなしている。また、抜止め部５２は、ハンマー等による衝撃により、拡開部４８の略全体に拡がって該拡開部４８を閉塞している。すなわち、抜止め部５２は、拡開部４８を閉塞した状態で該拡開部４８に係合しており、これにより、抜止め部５２が縮径部４６を通過不能となって、固定突起４２の固定孔４４に対する抜け止めが図られる。また、固定突起４２の本体部４２ａは、ハンマー等による衝撃で、縮径部４６の長手方向の縁部に案内されて仕切板２８,３０の延在方向に拡がり、縮径部４６との間の前記スペースＳ1,Ｓ1を埋めるようになっている。 An end portion side of the fixing protrusion 42 is constituted by a retaining portion 52 formed by crushing an end portion protruding from the upper surface 12 of the ice making substrate 16 through the fixing hole 44 with a hammer or the like. As shown in FIGS. 3A to 3C, the upper surface of the retaining portion 52 forms substantially the same surface as the upper surface 12 of the ice making substrate 16, and the upper surface of the retaining portion 52 is the fixed protrusion 42. The main body portion 42a (the portion located in the reduced diameter portion 46) has a shape that is slightly larger than the cross-sectional shape. Further, the retaining portion 52 is spread over substantially the entire expanded portion 48 by an impact caused by a hammer or the like and closes the expanded portion 48. In other words, the retaining portion 52 is engaged with the expanded portion 48 in a state where the expanded portion 48 is closed, thereby preventing the retaining portion 52 from passing through the reduced diameter portion 46 and fixing protrusions. 42 is prevented from coming off from the fixing hole 44. The main body portion 42 a of the fixed protrusion 42 is guided by the longitudinal edge of the reduced diameter portion 46 due to an impact by a hammer or the like and expands in the extending direction of the partition plates 28, 30. The spaces S 1 and S 1 are filled.

(実施例１の作用)
次に、実施例１の製氷部４０の作用について説明を行う。製氷部４０を製造する際には、先ず始めに、横方向仕切板２８の下向きスリット３２および縦方向仕切板３０の上向きスリット３４を相互に係合させ、両仕切板２８,３０を格子状に組付けて仕切部材２２を完成させる。次に、製氷室２６の内部空間に仕切部材２２を収容し、各固定突起４２を対応の固定孔４４に挿通させる。このとき、図２(ａ)に示すように、固定孔４４の縮径部４６における長手方向の縁部が、固定突起４２の長手方向の側面に当接する。各仕切板２８,３０の上端縁部が製氷基板１６の下面１８に当接するまで固定突起４２を固定孔４４に挿通すると、図２(ｂ),(ｃ)に示すように、該固定突起４２の端部が固定孔４４を介して製氷基板１６の上面１２から上方へ突出する。 (Operation of Example 1)
Next, the operation of the ice making unit 40 of Example 1 will be described. When manufacturing the ice making unit 40, first, the downward slit 32 of the horizontal partition plate 28 and the upward slit 34 of the vertical partition plate 30 are engaged with each other, so that both the partition plates 28 and 30 are formed in a lattice shape. The partition member 22 is completed by assembling. Next, the partition member 22 is accommodated in the internal space of the ice making chamber 26, and each fixing protrusion 42 is inserted into the corresponding fixing hole 44. At this time, as shown in FIG. 2A, the edge in the longitudinal direction of the reduced diameter portion 46 of the fixing hole 44 contacts the side surface in the longitudinal direction of the fixing protrusion 42. When the fixing protrusions 42 are inserted into the fixing holes 44 until the upper edge portions of the partition plates 28 and 30 come into contact with the lower surface 18 of the ice making substrate 16, as shown in FIGS. 2 (b) and 2 (c), the fixing protrusions 42. The end of the projection protrudes upward from the upper surface 12 of the ice making substrate 16 through the fixing hole 44.

次に、製氷基板１６の上面１２から突出する固定突起４２の端部をハンマー等で圧潰すると、図３(ｂ)に示すように、固定突起４２が縮径部４６の長手方向の縁部に案内されて仕切板２８,３０の延在方向に拡がって、固定突起４２の本体部４２ａと縮径部４６との間のスペースＳ1,Ｓ1が埋まる。また、固定突起４２の端部は、該固定突起４２の長手方向および短手方向に拡がって、図３(ａ)〜(ｃ)に示すように、拡開部４８の略全体を閉塞した状態で抜止め部５２が形成される。すなわち、抜止め部５２が拡開部４８を閉塞することで、固定突起４２と固定孔４４との間に隙間が生ずるのを抑制すると共に、抜止め部５２が拡開部４８に係合し、固定突起４２の固定孔４４に対する抜け止めが達成される。 Next, when the end portion of the fixed protrusion 42 protruding from the upper surface 12 of the ice making substrate 16 is crushed with a hammer or the like, the fixed protrusion 42 is formed on the longitudinal edge of the reduced diameter portion 46 as shown in FIG. The space S 1 , S 1 between the main body portion 42 a of the fixing protrusion 42 and the reduced diameter portion 46 is filled by being guided and expanded in the extending direction of the partition plates 28, 30. Further, the end portion of the fixed protrusion 42 extends in the longitudinal direction and the short direction of the fixed protrusion 42, and as shown in FIGS. 3 (a) to 3 (c), substantially the entire expanded portion 48 is closed. Thus, the retaining portion 52 is formed. That is, the retaining portion 52 blocks the widened portion 48, thereby preventing a gap from being formed between the fixing protrusion 42 and the fixing hole 44, and the retaining portion 52 is engaged with the widened portion 48. The retaining of the fixing protrusion 42 with respect to the fixing hole 44 is achieved.

製氷基板１６(製氷室２６)に仕切部材２２を固定した後、製氷基板１６の上面１２に蒸発管１４を取り付ける。このとき、抜止め部５２の上面が製氷基板１６の上面１２と略同一面を形成するので、蒸発管１４を製氷基板１６に取付ける際に、抜止め部５２が邪魔にならず、取付作業の効率が低下することもない。製氷基板１６に蒸発管１４が固定されると、製氷部４０が構成される。次に、この製氷部４０に対し、錫によるめっき処理を行う。このとき、固定孔４４の拡開部４８は抜止め部５２で閉塞され、固定突起４２および固定孔４４の間に隙間が生じていないので、めっき時に錫が隙間に溜まって固着するのを防止し得る。なお、固定孔４４および固定突起４２の間に隙間が生じないことから、製氷部４０の使用時に隙間に水が溜まることもない。めっき処理を行った後、製氷部４０が完成する。   After fixing the partition member 22 to the ice making substrate 16 (ice making chamber 26), the evaporation tube 14 is attached to the upper surface 12 of the ice making substrate 16. At this time, since the upper surface of the retaining portion 52 forms substantially the same surface as the upper surface 12 of the ice making substrate 16, the retaining portion 52 does not get in the way when the evaporation tube 14 is attached to the ice making substrate 16. The efficiency is not reduced. When the evaporation tube 14 is fixed to the ice making substrate 16, an ice making unit 40 is configured. Next, the ice making part 40 is plated with tin. At this time, the widened portion 48 of the fixing hole 44 is closed by the retaining portion 52, and no gap is formed between the fixing protrusion 42 and the fixing hole 44. Therefore, tin is prevented from collecting and fixing in the gap during plating. Can do. Since no gap is generated between the fixing hole 44 and the fixing protrusion 42, water does not accumulate in the gap when the ice making unit 40 is used. After the plating process, the ice making unit 40 is completed.

以上に説明したように、実施例１に係る製氷部４０は、抜止め部５２が拡開部４８を閉塞するよう圧潰された状態で固定孔４４に係合するので、仕切部材２２を製氷基板１６に強固に固定することができる。また、固定突起４２および固定孔４４の間に隙間が生じ難くして、隙間に錫や水が溜まるのを防止し得るので、錫めっきが剥離したり製氷部４０の製品寿命が低下するのを抑制し得る。更に、固定突起４２の断面形状を仕切部材２２の長手方向に沿って長尺な矩形状としたので、固定突起４２の強度を向上することができ、仕切部材２２を製氷基板１６に強固に固定することが可能となる。なお、固定突起４２の本体部４２ａが縮径部４６との間のスペースＳ1,Ｓ1を埋めるので、固定突起４２の固定孔４４に対する係合力がより強くなり、仕切部材２２を製氷基板１６に強固に固定し得る。 As described above, the ice making unit 40 according to the first embodiment engages with the fixing hole 44 in a state in which the retaining portion 52 is crushed so as to close the expanding portion 48, so that the partition member 22 is connected to the ice making substrate. 16 can be firmly fixed. Further, since it is difficult for a gap to be formed between the fixing protrusion 42 and the fixing hole 44 and it is possible to prevent the accumulation of tin and water in the gap, the tin plating is peeled off and the product life of the ice making part 40 is reduced. Can be suppressed. Further, since the cross-sectional shape of the fixing protrusion 42 is a long rectangular shape along the longitudinal direction of the partition member 22, the strength of the fixing protrusion 42 can be improved, and the partition member 22 is firmly fixed to the ice making substrate 16. It becomes possible to do. In addition, since the main body portion 42a of the fixed protrusion 42 fills the spaces S 1 and S 1 between the reduced diameter portion 46, the engaging force of the fixed protrusion 42 with respect to the fixed hole 44 becomes stronger, and the partition member 22 is attached to the ice making substrate 16. It can be firmly fixed to.

次に、実施例２に係る自動製氷機の製氷部について、以下説明を行う。なお、実施例２では、実施例１と相違する箇所についてのみ説明を行い、実施例１と同一の部材については、同じ符号を付して説明を省略する。   Next, the ice making unit of the automatic ice making machine according to the second embodiment will be described below. In the second embodiment, only portions different from the first embodiment will be described, and the same members as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

図４は、実施例２に係る自動製氷機の製氷部６０を製氷基板１６の下面１８側から見た全体図である。実施例２では、仕切部材６２は、複数の円筒体６４から構成されている。この円筒体６４は、図５に示すように、長尺なパイプを所定長さでカットして形成されたものであって、上下方向に開放して内部に円柱状の製氷小室６０ａが画成されている。円筒体６４の上端縁部(端縁部)には、複数(実施例では、４つ)の固定突起６６が上方に突設されている。図７(ａ),(ｂ)に示すように、固定突起６６の突出量は、製氷基板１６の板厚よりも大きく設定されている。図６に示すように、固定突起６６の断面形状は、円筒体６４の周面に沿った円弧形状をなしている。また、固定突起６６の厚み(径方向の寸法)は、円筒体６４の厚みに一致しており、固定突起６６の円弧長さは、固定突起６６の厚みより十分大きく設定されている。なお、実施例２では、固定突起６６の円弧長さが該固定突起６６の厚みの２倍以上となっている。   FIG. 4 is an overall view of the ice making unit 60 of the automatic ice making machine according to the second embodiment when viewed from the lower surface 18 side of the ice making substrate 16. In the second embodiment, the partition member 62 includes a plurality of cylindrical bodies 64. As shown in FIG. 5, the cylindrical body 64 is formed by cutting a long pipe with a predetermined length. The cylindrical body 64 is opened in the vertical direction to define a cylindrical ice making chamber 60a. Has been. A plurality (four in the embodiment) of fixing projections 66 project upward from an upper end edge (end edge) of the cylindrical body 64. As shown in FIGS. 7A and 7B, the protruding amount of the fixed protrusion 66 is set larger than the thickness of the ice making substrate 16. As shown in FIG. 6, the cross-sectional shape of the fixed protrusion 66 is an arc shape along the peripheral surface of the cylindrical body 64. In addition, the thickness (diameter dimension) of the fixed protrusion 66 matches the thickness of the cylindrical body 64, and the arc length of the fixed protrusion 66 is set sufficiently larger than the thickness of the fixed protrusion 66. In the second embodiment, the arc length of the fixed projection 66 is twice or more the thickness of the fixed projection 66.

前記製氷基板１６には、各固定突起６６に対応して複数の固定孔６８が上下方向に開放して形成されている。この固定孔６８は、図７(ａ),(ｂ)に示すように、製氷基板１６の下面１８側に位置する縮径部７０と、製氷基板１６の上面１２側に位置する拡開部７２とから構成され、前記固定突起６６が挿通されるようになっている。前記縮径部７０は、前記製氷基板１６の上下方向に同一の開口寸法で穿設されており、縮径部７０の開口形状は、固定突起６６の断面形状と同一の曲率および中心を有する円弧形状をなしている(図６参照)。また、図６,図７(ａ)に示すように、縮径部７０の円弧長さは、固定突起６６の円弧長さより大きく設定されており、固定突起６６を固定孔６８に挿通した際に、固定突起６６の径方向の側面と、縮径部７０の径方向の縁部との間にスペースＳ2,Ｓ2が画成されるようになっている。更に、縮径部７０の径方向の寸法は、図６,図７(ｂ)に示すように、固定突起６６の厚みと略一致しており、固定突起６６を固定孔６８に挿通した際に、縮径部７０の円弧部分の縁部が固定突起６６の円弧部分の側面に当接するようになっている。 A plurality of fixing holes 68 are formed in the ice making substrate 16 so as to correspond to the fixing protrusions 66 and open in the vertical direction. As shown in FIGS. 7A and 7B, the fixing hole 68 includes a reduced diameter portion 70 located on the lower surface 18 side of the ice making substrate 16 and an expanded portion 72 located on the upper surface 12 side of the ice making substrate 16. The fixing protrusion 66 is inserted through the structure. The reduced diameter portion 70 is formed with the same opening size in the vertical direction of the ice making substrate 16, and the opening shape of the reduced diameter portion 70 is an arc having the same curvature and center as the cross-sectional shape of the fixed protrusion 66. It has a shape (see FIG. 6). Further, as shown in FIGS. 6 and 7A, the arc length of the reduced diameter portion 70 is set to be larger than the arc length of the fixed projection 66, and when the fixed projection 66 is inserted into the fixed hole 68. Spaces S 2 and S 2 are defined between the radial side surface of the fixed protrusion 66 and the radial edge of the reduced diameter portion 70. Further, as shown in FIGS. 6 and 7B, the radial dimension of the reduced diameter portion 70 is substantially the same as the thickness of the fixed protrusion 66, and when the fixed protrusion 66 is inserted into the fixed hole 68. The edge of the arc portion of the reduced diameter portion 70 is in contact with the side surface of the arc portion of the fixed projection 66.

前記拡開部７２は、前記縮径部７０の上縁部に連設されて、該縮径部７０より大きな開口面積を有している。拡開部７２は、製氷基板１６の下面１８から上面１２へ向かうにつれて次第に開口面積が拡がるよう付されたテーパ７４により構成されており、拡開部７２の製氷基板１６の上面１２における開口形状は、前記縮径部７０を一回り大きくした円弧形状をなしている(図６参照)。前記テーパ７４は、実施例１のテーパ５０と同様に、縮径部７０の上縁部から製氷基板１６の上面１２に向けて直線的に傾斜している。   The expanded portion 72 is connected to the upper edge portion of the reduced diameter portion 70 and has a larger opening area than the reduced diameter portion 70. The expanding portion 72 is configured by a taper 74 attached so that the opening area gradually increases from the lower surface 18 to the upper surface 12 of the ice making substrate 16. The opening shape of the expanding portion 72 on the upper surface 12 of the ice making substrate 16 is as follows. An arc shape is formed by enlarging the reduced diameter portion 70 (see FIG. 6). Similar to the taper 50 of the first embodiment, the taper 74 is linearly inclined from the upper edge portion of the reduced diameter portion 70 toward the upper surface 12 of the ice making substrate 16.

図８(ａ),(ｂ)に示すように、前記固定突起６６の端部側は、固定孔６８に挿通された状態で、前記製氷基板１６の上面１２から突出する端部がハンマー等で圧潰されることで形成される抜止め部７６で構成されている。この抜止め部７６は、実施例１の抜止め部５２と同様に、ハンマー等による衝撃により、拡開部７２の略全体に拡がって該拡開部７２を閉塞しており、これにより、抜止め部７６が拡開部７２に係合して、固定突起６６の固定孔６８に対する抜け止めが図られる。更に、図８(ａ)に示すように、ハンマー等による衝撃により、固定突起６６の本体部６６ａ(固定突起６６における縮径部７０に位置する部分)が縮径部７０の円弧部分の縁部に案内されて拡がって、縮径部７０との間の前記スペースＳ2,Ｓ2を埋めるようになっている。 As shown in FIGS. 8A and 8B, the end of the fixing protrusion 66 is inserted into the fixing hole 68, and the end protruding from the upper surface 12 of the ice making substrate 16 is a hammer or the like. The retaining portion 76 is formed by being crushed. Similar to the retaining portion 52 of the first embodiment, the retaining portion 76 is spread over substantially the entire expanded portion 72 by the impact of a hammer or the like, thereby closing the expanded portion 72. The stop portion 76 engages with the expanded portion 72, and the fixing protrusion 66 is prevented from coming off from the fixing hole 68. Further, as shown in FIG. 8 (a), the main body 66a of the fixed projection 66 (the portion located at the reduced diameter portion 70 of the fixed projection 66) is the edge of the arc portion of the reduced diameter portion 70 due to impact by a hammer or the like. The space S 2 , S 2 between the reduced diameter portion 70 is filled up.

ここで、実施例２の製氷部６０では、図４に示すように、円筒体６４は、隣接する円筒体６４,６４同士の側面が当接した状態で製氷基板１６に配設されるようになっている。また、円筒体６４は、互いに隣接する３つの円筒体６４,６４,６４の中心が正三角形をなすよう配置されている(図４の一点鎖線参照)。すなわち、円筒体６４は、製氷基板１６の短手方向(図４の左右方向)に直線状に並んで列をなすよう配置されると共に、製氷基板１６の長手方向(図４の上下方向)に並ぶ円筒体６４の列が、円筒体６４の半径分だけ短手方向に互いにズレて配置されている。このように円筒体６４を配設することで、隣接する円筒体６４間のデッドスペースを極力小さくして、製氷基板１６に配設し得る円筒体６４の数を稼ぎ、製氷部６０の製氷能力の向上が図られている。   Here, in the ice making unit 60 of the second embodiment, as shown in FIG. 4, the cylindrical body 64 is arranged on the ice making substrate 16 with the side surfaces of the adjacent cylindrical bodies 64, 64 in contact with each other. It has become. Further, the cylindrical body 64 is arranged such that the centers of the three cylindrical bodies 64, 64, 64 adjacent to each other form an equilateral triangle (see the one-dot chain line in FIG. 4). That is, the cylindrical bodies 64 are arranged in a line in a straight line in the short direction of the ice making substrate 16 (left and right direction in FIG. 4), and in the longitudinal direction of the ice making substrate 16 (up and down direction in FIG. 4). The aligned rows of cylindrical bodies 64 are arranged so as to be shifted from each other in the lateral direction by the radius of the cylindrical body 64. By arranging the cylindrical bodies 64 in this way, the dead space between the adjacent cylindrical bodies 64 is made as small as possible, the number of cylindrical bodies 64 that can be arranged on the ice making substrate 16 is increased, and the ice making capacity of the ice making unit 60 is increased. Improvements are being made.

以上のように、実施例２に係る自動製氷機の製氷部６０によれば、実施例１と同様に、円筒体６４(仕切部材６２)を製氷基板１６に強固に固定することができる。また、抜止め部７６が拡開部７２を閉塞するので、固定突起６６と固定孔６８との間に隙間が殆ど生じることがなく、隙間にめっき処理時の錫や使用時の水が溜るのを防止し得る。これにより、錫めっきの剥離や製氷部６０の製品寿命が低下するのを抑制し得る。更に、固定突起６６の断面形状を円筒体６４に沿う円弧形状としたので、固定突起６６の強度を向上することができ、円筒体６４(仕切部材６２)を製氷基板１６に強固に固定することが可能となる。なお、固定突起６６の本体部６６ａが縮径部７０とのスペースＳ2,Ｓ2を埋めるので、固定突起６６が固定孔６８に強固に係合して、円筒体６４を製氷基板１６に確実に固定することができる。 As described above, according to the ice making unit 60 of the automatic ice maker according to the second embodiment, the cylindrical body 64 (partition member 62) can be firmly fixed to the ice making substrate 16 as in the first embodiment. Further, since the retaining portion 76 closes the expanded portion 72, there is almost no gap between the fixed projection 66 and the fixed hole 68, and tin at the time of plating or water at the time of use is collected in the gap. Can prevent. Thereby, it can suppress that peeling of a tin plating and the product life of the ice making part 60 fall. Furthermore, since the cross-sectional shape of the fixing protrusion 66 is an arc shape along the cylindrical body 64, the strength of the fixing protrusion 66 can be improved, and the cylindrical body 64 (partition member 62) can be firmly fixed to the ice making substrate 16. Is possible. Since the main body portion 66a of the fixed projection 66 fills the spaces S 2 and S 2 with the reduced diameter portion 70, the fixed projection 66 is firmly engaged with the fixed hole 68, and the cylindrical body 64 is securely attached to the ice making substrate 16. Can be fixed to.

なお、本発明に係る自動製氷機の製氷部としては、実施例の構成に限定されず、以下の如き変更が可能である。
