 (構成)
 本実施形態の磁気ヒートポンプ装置の基本構成は、図1に示す従来構成と同様であるが、周方向に配列した作業室を有する材料容器の構造が異なる。このため以下、本実施形態の材料容器について説明する。
 本実施形態の材料容器10は、図3及び図4に示すように、同心状に配置される内径側円筒部品11及び外径側円筒部品12と、複数の扇状容器13と、を備える。なお、内径側円筒部品11、外径側円筒部品12、及び複数の扇状容器13はそれぞれ別部品である。
Next, embodiments of the present invention will be described with reference to the drawings.
(Constitution)
The basic configuration of the magnetic heat pump device of the present embodiment is the same as the conventional configuration shown in FIG. 1, but the structure of the material container having the work chambers arranged in the circumferential direction is different. Therefore, the material container of the present embodiment will be described below.
As shown in FIGS. 3 and 4, the material container 10 of the present embodiment includes the radially inner cylindrical component 11 and the radially outer cylindrical component 12 arranged concentrically, and a plurality of fan-shaped containers 13. The inner diameter side cylindrical part 11, the outer diameter side cylindrical part 12, and the plurality of fan-shaped containers 13 are separate parts.
 <円筒部品>
 内径側円筒部品11及び外径側円筒部品12は、例えば鋼やアルミニウムなどの金属製であり、永久磁石の回転軸Pに対して同心状に配置される。
 内径側円筒部品11の外径面の径よりも外径側円筒部品12の内径面の径が大きい。これによって、内径側円筒部品11及び外径側円筒部品12を同心に配置すると、内径側円筒部品11と外径側円筒部品12との間に、円筒状の空間が形成される。
<Cylinder parts>
The inner diameter side cylindrical component 11 and the outer diameter side cylindrical component 12 are made of metal such as steel or aluminum, for example, and are arranged concentrically with the rotation axis P of the permanent magnet.
The diameter of the inner diameter surface of the outer diameter side cylindrical component 12 is larger than the diameter of the outer diameter surface of the inner diameter side cylindrical component 11. By this, when the inner diameter side cylindrical component 11 and the outer diameter side cylindrical component 12 are arranged concentrically, a cylindrical space is formed between the inner diameter side cylindrical component 11 and the outer diameter side cylindrical component 12.
 <扇状容器13>
 本実施形状の扇状容器13は、作業室を形成する部品であって、樹脂製である。扇状容器13に使用する樹脂材料は、ガラス転移温度若しくは融点が、磁気ヒートポンプ装置で発生させる加熱温度の上限値よりも高いものであれば特に限定されない。
 扇状容器13は、図4及び図5に示すように、内径側円筒部品11の外径面に摺接する内径側円弧部13a、外径側円筒部品12の内径面に摺接する外径側円弧部13b、及び内径側円弧部と外径側円弧部との周方向両端部とを連結する一対の壁部13cが一体に成形されて作業室を形成する閉断面形状となっている。すなわち、扇状容器13は、閉断面形状で且つ軸方向両端部が開口した筒形状となっている。
Fan-like container 13
The fan-shaped container 13 of the present embodiment is a component that forms a working chamber, and is made of resin. The resin material used for the fan-shaped container 13 is not particularly limited as long as the glass transition temperature or the melting point is higher than the upper limit value of the heating temperature generated by the magnetic heat pump device.
As shown in FIGS. 4 and 5, the fan-shaped container 13 has an inner diameter side arc portion 13a slidingly contacting the outer diameter surface of the inner diameter side cylindrical part 11 and an outer diameter side arc portion slidingly contacting the inner diameter surface of the outer diameter side cylindrical part 12. 13b and a pair of wall portions 13c connecting the radially inner side arc portion and the circumferentially opposite end portions of the radially outer side arc portion are integrally formed to form a closed cross-sectional shape forming a working chamber. That is, the fan-shaped container 13 has a closed cross-sectional shape and a cylindrical shape in which both axial ends are open.
 このような形状の複数の扇状容器13が、図3及び図4のように、内径側円筒部品11と外径側円筒部品12との間に形成される円筒状の空間に、円周方向に沿って配列している。なお、一対の壁部の外面は、永久磁石の回転軸Pを中心とした放射状の線に沿った面形状となっていることが好ましい。
 円筒状の空間に配列した複数の扇状容器13の組は、周方向にガタがないように設計することが好ましい。例えば、軸方向からみて、図4に示すように、永久磁石の回転軸Pを中心とした周方向の角度が30度となるように一対の壁部13cの外面を設計した場合には、12個の扇状容器13を配列すれば良い。すなわち、配列する扇状容器13の上記角度の合計が360度となるように設計する。なお、角度の合計が360度になれば、各扇状容器13の上記角度が同一である必要はない。
In the cylindrical space formed between the inner diameter side cylindrical component 11 and the outer diameter side cylindrical component 12 as shown in FIGS. Arranged along. In addition, it is preferable that the outer surfaces of the pair of wall portions have a surface shape along a radial line around the rotation axis P of the permanent magnet.
The set of fan-shaped containers 13 arranged in a cylindrical space is preferably designed so that there is no backlash in the circumferential direction. For example, as shown in FIG. 4 when viewed from the axial direction, when the outer surface of the pair of wall portions 13c is designed so that the angle in the circumferential direction about the rotation axis P of the permanent magnet is 30 degrees, 12 The fan-shaped containers 13 may be arranged. That is, it is designed so that the sum total of the above-mentioned angle of fan-like container 13 to arrange will be 360 degrees. In addition, if the sum of angles is 360 degrees, the said angle of each fan-shaped container 13 does not need to be the same.
 [分割体14]
 各扇状容器13は、図5に示すように、材料容器10の軸方向(磁気ヒートポンプ装置の軸方向)に沿って分割された複数の分割体14から構成されている。
 分割体14は、射出成形などで一体成形されて作製される。
 ここで、扇状容器13を軸方向に分割した複数の分割体14から構成する場合には、例えば軸方向に型分割して成形される。このとき、抜きテーパの寸法が影響しない範囲の軸長で分割して各分割体14を作製することが好ましい。このため、各分割体14の軸方向の長さを、例えば10mm以上30mm以下の範囲とすることが好ましい。なお、各分割体14の長さは異なっていても良い。
[Division 14]
Each fan-shaped container 13 is comprised from the some division body 14 divided | segmented along the axial direction (axial direction of a magnetic heat pump apparatus) of the material container 10, as shown in FIG.
The divided body 14 is manufactured integrally by injection molding or the like.
Here, in the case where the fan-shaped container 13 is constituted by a plurality of divided bodies 14 divided in the axial direction, for example, the dies are divided in the axial direction and molded.
