Description

衣類乾燥機Clothes dryer
　本開示は、循環風路にフィルタを備えた衣類乾燥機に関する。 The present disclosure relates to a clothes dryer provided with a filter in a circulation air passage.
　特許文献１は、洗濯機の循環風路に設けられ、リント等の異物を捕捉するフィルタを開示する。この乾燥機用のフィルタは、枠体と、枠体に保持され、縦糸と横糸を織り込んでシート状に形成されるメッシュ部とを備える。また、メッシュ部においては、縦糸と横糸の表面に金属皮膜が形成されており、メッシュ部で補足した塵埃等を廃棄する際の清掃性が向上するように構成されている。 Patent Document 1 discloses a filter that is provided in a circulation air passage of a washing machine and captures foreign substances such as lint. The filter for a dryer includes a frame, and a mesh portion held by the frame and formed into a sheet by interweaving warp and weft. Further, in the mesh portion, a metal film is formed on the surface of the warp and the weft, so that the cleaning property at the time of discarding dust and the like captured by the mesh portion is improved.
　図３は、従来の乾燥機用のフィルタ装置におけるメッシュ部の拡大模式図である。従来のメッシュ部は、図３のように、横糸と縦糸を織り込むことで、規則的に配列された四角状の孔を形成している。 FIG. 3 is an enlarged schematic view of a mesh portion in a conventional filter device for a dryer. In the conventional mesh part, as shown in FIG. 3, weft yarns and warp yarns are interwoven to form regularly arranged square holes.
特開２０１４－１６１４４５号公報JP 2014-161445 A
　しかしながら、上記従来の構成では、メッシュ部材は、縦糸と横糸を織り込んで形成されているため、縦糸と横糸との交差部に段差が形成されていた。そのため、段差部分にリント等の塵が絡まりやすく、フィルタに堆積した塵を廃棄する際、段差部分に引っかかった塵を除去することが難しいという問題があった。また、段差部分の塵の堆積が進行すると、メッシュ部材が目詰まりし、乾燥機能の低下に伴って消費電力が増加するという問題があった。 However, in the above-described conventional configuration, since the mesh member is formed by weaving the warp and the weft, a step is formed at the intersection of the warp and the weft. Therefore, there is a problem that dust such as lint is easily entangled in the step portion, and it is difficult to remove dust stuck on the step portion when discarding dust accumulated on the filter. In addition, when the accumulation of dust on the stepped portion progresses, the mesh member is clogged, and there is a problem that power consumption increases as the drying function decreases.
　本開示は、異物が乾燥フィルタに絡まりにくい衣類乾燥機を提供する。 The present disclosure provides a clothes dryer in which foreign substances are less likely to be entangled in the drying filter.
　本開示における衣類乾燥機は、筐体と、前記筐体内に回転自在に配設される回転槽と、前記回転槽と連通し、前記回転槽内の空気を循環させる循環風路と、を備える。また、前記循環風路には、前記循環風路の空気を加熱する加熱部と、前記循環風路に送風する送風部と、異物を捕獲するフィルタ装置と、が設けられる。さらに、前記フィルタ装置は、枠体と、複数の貫通孔が設けられた金属板により構成されたメッシュ部と、を有する。 The clothes dryer according to the present disclosure includes a housing, a rotating tub rotatably disposed in the housing, and a circulation air passage communicating with the rotating tub and circulating air in the rotating tub. . The circulation air passage is provided with a heating unit that heats the air in the circulation air passage, a blowing unit that blows air into the circulation air passage, and a filter device that captures foreign matter. Further, the filter device has a frame and a mesh portion made of a metal plate provided with a plurality of through holes.

　続いて、図２Ａ及び図２Ｂを用いて、フィルタ装置について説明する。 Next, the filter device will be described with reference to FIGS. 2A and 2B.
　図２Ａにおいて、フィルタ装置２４は、枠体２４ａと、メッシュ部２４ｃとを備えている。枠体２４ａの左右の側面には、枠体係止部２４ｅが形成されている。フィルタ装置収容部２５には、収容部係止部（図示せず）が配設されている。より具体的には、フィルタが収納された状態で、枠体係止部２４ｅに対向する位置に、収容部係止部（図示せず）が配設されている。枠体係止部２４ｅは、収容部係止部と係合することで、フィルタ装置２４をヒートポンプケース１７に固定する。 2A, the filter device 24 includes a frame 24a and a mesh portion 24c. On the left and right side surfaces of the frame 24a, frame locking portions 24e are formed. The filter device housing portion 25 is provided with a housing portion locking portion (not shown). More specifically, a housing locking portion (not shown) is provided at a position facing the frame body locking portion 24e in a state where the filter is stored. The frame body locking portion 24 e fixes the filter device 24 to the heat pump case 17 by engaging with the housing portion locking portion.
　図２Ｂ及び図２Ｃにおいて、メッシュ部２４ｃは、枠体２４ａから延伸する格子部２４ｂにより支持されている。格子部２４ｂは、メッシュ部２４ｃの背面に配置されている。格子部２４ｂは、インサート成形によりメッシュ部２４ｃと固定されている。 2B and 2C, the mesh part 24c is supported by a lattice part 24b extending from the frame 24a. The lattice part 24b is arranged on the back of the mesh part 24c. The lattice part 24b is fixed to the mesh part 24c by insert molding.
　図２Ｄは、メッシュ部２４ｃの拡大模式図である。実施の形態１におけるメッシュ部２４ｃは、ステンレスにより板状に形成されている。メッシュ部２４ｃの厚みは、０．１～０．１５ｍｍとなるように構成される。メッシュ部２４ｃの表面には、エッチング加工により多数の円形の細孔２４ｄが形成されている。細孔２４ｄのサイズは、直径０．２～０．２５ｍｍとなっており、メッシュ部２４ｃにおける空気抵抗を小さくしつつも異物の捕集を損なわない。メッシュ部２４ｃの開口率は、５０～７５％となる。開口率を極端に大きくすると、メッシュ部２４ｃの強度が不足する虞があるため、上記範囲が望ましい。 FIG. 2D is an enlarged schematic diagram of the mesh portion 24c. The mesh part 24c in the first embodiment is formed in a plate shape from stainless steel. The mesh portion 24c is configured to have a thickness of 0.1 to 0.15 mm. A large number of circular pores 24d are formed on the surface of the mesh portion 24c by etching. The size of the pores 24d is 0.2 to 0.25 mm in diameter, and does not impair the collection of foreign substances while reducing the air resistance in the mesh portion 24c. The aperture ratio of the mesh part 24c is 50 to 75%. If the aperture ratio is extremely large, the strength of the mesh portion 24c may be insufficient, so the above range is desirable.
　以上のように構成された洗濯乾燥機について、その動作を以下説明する。 動作 The operation of the washer / dryer configured as described above will be described below.
　ユーザが、内槽５内に洗濯物を投入し、操作表示部（図示せず）を操作すると、洗濯運転が開始される。洗濯運転の詳細については割愛する。洗濯運転が終了すると、引き続き乾燥運転が開始される。乾燥運転が開始されると、送風ファン１１は、外槽３及び内槽５内の空気を吸引する。内槽５は、モータ６により回転駆動される。これにより、内槽５内に収容された衣類が上下左右に攪拌される。 洗濯 When the user puts laundry into the inner tub 5 and operates an operation display unit (not shown), a washing operation is started. The details of the washing operation are omitted. When the washing operation is completed, the drying operation is started. When the drying operation is started, the blower fan 11 sucks the air in the outer tub 3 and the inner tub 5. The inner tank 5 is driven to rotate by a motor 6. Thereby, the clothes accommodated in the inner tank 5 are stirred up, down, left and right.
　外槽３から吸引された空気は、第１の循環風路１２を通りフィルタ装置２４に送られる。リント等の異物は、吸引された空気がフィルタ装置を通過する際に、メッシュ部２４ｃにより捕獲される。フィルタ装置を通過した空気は、除湿部２０により除湿され、加熱部２１により加熱される。このように乾燥された温風は、送風ファン１１により第２の循環経路を経て、内槽５内へと送風される。以上の動作を繰り返すことで、洗濯機は、内槽５内の洗濯物の水分を蒸発させ、洗濯物を乾燥させる。内槽５内の空気が予め設定された乾燥率を超えると、乾燥運転が終了する。 空 気 The air sucked from the outer tank 3 is sent to the filter device 24 through the first circulation air passage 12. Foreign matter such as lint is captured by the mesh portion 24c when the sucked air passes through the filter device. The air that has passed through the filter device is dehumidified by the dehumidifying unit 20 and heated by the heating unit 21. The hot air dried in this way is blown into the inner tank 5 through the second circulation path by the blower fan 11. By repeating the above operation, the washing machine evaporates the moisture of the laundry in the inner tub 5 and dries the laundry. When the air in the inner tank 5 exceeds the preset drying rate, the drying operation ends.
　続いて、フィルタ装置の作用について説明する。 Next, the operation of the filter device will be described.
　フィルタ装置は、メッシュ部２４ｃが空気の流れと対向するように、フィルタ装置収容部２５に着脱自在に配設されている。従って、乾燥運転時には、水蒸気を含む温風がメッシュ部２４ｃに吹き付けられる。衣類に付着していたリントや埃等の塵は、回転駆動や温風により衣類から取り除かれ、空気の流れに乗ってフィルタ装置へと送られる。メッシュ部２４ｃは、空気の流れと対向しているため、リント等の異物が捕集しやすい向きとなっている。 The filter device is detachably provided in the filter device housing 25 so that the mesh portion 24c faces the flow of air. Therefore, at the time of the drying operation, warm air containing steam is blown to the mesh portion 24c. Dust such as lint and dust adhering to the clothes is removed from the clothes by rotational driving or warm air, and is sent to the filter device by riding the flow of air. Since the mesh portion 24c is opposed to the flow of air, the mesh portion 24c is oriented so that foreign substances such as lint are easily collected.
　図２Ｄにおいて、本実施の形態におけるメッシュ部２４ｃは、織物を利用するのではなく、板材に円形の細孔２４ｄが開けられて形成されている。従って、細孔２４ｄの周囲においては、表面に段差が無くかつ孔内に角がない。これにより、リント等の異物が細孔２４ｄの周囲に引っかかりづらいので、ユーザはメッシュ部２４ｃからリント等を容易に取り除くことできる。また、細孔２４ｄの形状を円形としたことにより、細孔２４ｄの内側には角が存在しない。これにより、角にリントが絡みつく現象を抑制し、フィルタ装置２４に溜まった塵埃を廃棄する際のお手入れ性を向上させることができる。 ＤIn FIG. 2D, the mesh portion 24c in the present embodiment is formed by opening circular holes 24d in a plate material instead of using a woven fabric. Therefore, there is no step on the surface and no corners in the hole around the fine hole 24d. This makes it difficult for foreign matter such as lint to be caught around the pores 24d, so that the user can easily remove lint and the like from the mesh portion 24c. Further, since the shape of the fine holes 24d is circular, no corner exists inside the fine holes 24d. Thereby, the phenomenon that the lint is entangled with the corner can be suppressed, and the careability in disposing of the dust accumulated in the filter device 24 can be improved.
　更に、メッシュ部２４ｃにおいては、エッチング加工により細孔２４ｄが形成されている。エッチング加工では、プレス加工において一般的である凹みやバリ等が発生しない。これにより、細孔２４ｄの周囲は、プレス加工品と比較して、凹凸が極めて少ない平滑な表面となっている。したがって、孔の周囲にリントが絡みつく現象を抑制できる。 Furthermore, in the mesh portion 24c, a fine hole 24d is formed by etching. In the etching process, dents, burrs, and the like, which are common in press working, do not occur. Thereby, the periphery of the fine holes 24d has a smooth surface with very few irregularities as compared with the pressed product. Therefore, the phenomenon that the lint is entangled around the hole can be suppressed.
　また、本発明におけるメッシュ部２４ｃは、板材はステンレス製であるため、防錆性、防腐食性が高く、長期にわたり品質を維持することができる。特に、衣類乾燥機におけるフィルタ装置は、高温、高質の環境下で使用されるため、ステンレスを用いることが望ましい。 メ ッ シ ュ Further, since the plate material of the mesh part 24c in the present invention is made of stainless steel, it has high rust prevention and corrosion resistance, and can maintain quality for a long time. In particular, since the filter device in the clothes dryer is used under a high temperature and high quality environment, it is desirable to use stainless steel.
　以上のように、本実施の形態において、衣類乾燥機は、筐体１と、筐体１内に回転自在に配設される内槽５と、内槽５と接続され、内槽５内の空気を循環させる循環風路と、を備える。また、循環風路には、循環風路の一部であるヒートポンプユニット内の空気を加熱する加熱部２１と、循環風路に送風する送風ファン１１と、異物を捕獲するフィルタ装置２４と、が設けられる。さらに、フィルタ装置２４は、枠体２４ａと、複数の細孔２４ｄが設けられた金属板により構成されたメッシュ部２４ｃと、を有する。これにより、段差にリント等の異物が引っかかることがないため、ユーザはフィルタ装置２４に付着した塵を捨てる際、軽くメッシュ部２４ｃを拭くだけでメッシュ部２４ｃを綺麗な状態に保つことができる。そのため、メッシュ部２４ｃはお手入れ性が高い。 As described above, in the present embodiment, the clothes dryer includes the housing 1, the inner tub 5 rotatably disposed in the housing 1, and the inner tub 5. A circulation air passage for circulating air. The circulation air passage includes a heating unit 21 for heating air in a heat pump unit which is a part of the circulation air passage, a blower fan 11 for blowing the circulation air passage, and a filter device 24 for capturing foreign matter. Provided. Further, the filter device 24 has a frame 24a and a mesh part 24c formed of a metal plate provided with a plurality of pores 24d. This prevents foreign matter such as lint from being caught on the step, so that when the user discards dust adhering to the filter device 24, the user can keep the mesh portion 24c clean by merely wiping the mesh portion 24c lightly. For this reason, the mesh portion 24c has high careability.
　本実施の形態のように、フィルタ装置２４は、循環風路において、加熱部２１の上流に配設されるようにしてもよい。これにより、加熱部２１の内部にリントが侵入することを防ぐことができる。 As in the present embodiment, the filter device 24 may be disposed upstream of the heating unit 21 in the circulation air passage. This can prevent lint from entering the inside of the heating unit 21.
　本実施の形態のように、メッシュ部２４ｃは、細孔２４ｄによる開口率が５０％以上、７５％以下となるように、エッチング加工により形成されるようにしてもよい。これにより、メッシュ部２４ｃの表面は、プレス加工品と比較して、凹凸が極めて少ない平滑な表面となっているので、メッシュ部の表面にリントが絡みつく現象を抑制できる。そのため、本発明におけるメッシュ部２４ｃはお手入れ性が高い。 As in the present embodiment, the mesh portion 24c may be formed by etching so that the aperture ratio of the fine holes 24d is 50% or more and 75% or less. Thereby, since the surface of the mesh portion 24c is a smooth surface with very few irregularities as compared with the pressed product, the phenomenon that the lint is entangled with the surface of the mesh portion can be suppressed. Therefore, the mesh part 24c in the present invention has high careability.
　本実施の形態のように、細孔２４ｄは、円形（略円形を含む）であるようにしてもよい。これにより、多角形の孔と比較すると、角がないためにリント等の異物が積層しづらい。そのため、お手入れ性が高い。 細孔 As in the present embodiment, the pores 24d may be circular (including substantially circular). As a result, as compared with a polygonal hole, foreign matters such as lint are less likely to be stacked because there are no corners. Therefore, the careability is high.
　（他の実施の形態）
　以上のように、本出願において開示する技術の例示として、実施の形態１を説明した。しかしながら、本開示における技術は、これに限定されず、変更、置き換え、付加、省略などを行った実施の形態にも適用できる。 (Other embodiments)
As described above, Embodiment 1 has been described as an example of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can be applied to embodiments in which changes, replacements, additions, omissions, and the like are made.
　そこで、以下、他の実施の形態を例示する。 Therefore, other embodiments will be exemplified below.
　実施の形態１では、衣類乾燥機の一例としてドラム式洗濯乾燥機を説明した。衣類乾燥機は、濡れた衣類を乾燥できるものであればよいので、ドラム式洗濯乾燥機に限定されない。従って、洗濯機能を有さない乾燥機であってもよいし、乾燥機能を有する縦型洗濯機であってもよい。 In the first embodiment, the drum type washer / dryer was described as an example of the clothes dryer. The clothes dryer is not limited to the drum type washer / dryer as long as it can dry wet clothes. Therefore, a dryer having no washing function or a vertical washing machine having a drying function may be used.
　実施の形態１では、フィルタの一例としてメッシュ部２４ｃを説明した。フィルタは、異物を捕捉できるものであればよいので、メッシュ部２４ｃが二つ以上配設されていてもよい。 In the first embodiment, the mesh unit 24c has been described as an example of the filter. The filter only needs to be able to capture foreign matter, and therefore two or more mesh portions 24c may be provided.
　実施の形態１では、フィルタの一例としてステンレスで形成されたフィルタ装置２４を説明した。フィルタは、ステンレスに限定されず、他の金属であっても構わない。ただし、ステンレスは、耐食性が高いため、高温高湿の空気を濾過する衣類乾燥機のフィルタにおいて好適に利用される。また、表面にめっき加工がされていてもよい。これにより、メッシュ部の耐食性を向上させることができるとともに、塵の付着を抑制することができる。 In the first embodiment, the filter device 24 made of stainless steel has been described as an example of the filter. The filter is not limited to stainless steel, and may be other metals. However, since stainless steel has high corrosion resistance, it is suitably used in a filter of a clothes dryer that filters high-temperature, high-humidity air. Further, the surface may be plated. Thereby, while being able to improve the corrosion resistance of a mesh part, adhesion of dust can be suppressed.
　実施の形態１では、孔の一例として円形の孔を説明した。孔は、円形に限定されず、四角形や六角形等の多角形であっても構わない。ただし、円形にしたことで、より角が少なくお手入れ性の高いメッシュ部を実現できる。また、ハニカム構造であっても構わない。ハニカム構造にすることで、強度を維持しつつも、開口率を大きくすることができる。また、多角形の孔の角部分を円弧状にしてもよい。これにより、円形の孔と同様、リント等の異物が積層しづらいという効果を得ることができる。 In the first embodiment, a circular hole has been described as an example of the hole. The hole is not limited to a circle, but may be a polygon such as a square or a hexagon. However, by making the shape circular, it is possible to realize a mesh part having fewer corners and high careability. Further, a honeycomb structure may be used. With the honeycomb structure, the aperture ratio can be increased while maintaining the strength. Further, the corners of the polygonal hole may be formed in an arc shape. Thereby, similarly to the circular hole, it is possible to obtain an effect that foreign matter such as lint is difficult to be laminated.
　なお、上述の実施の形態は、本開示における技術を例示するためのものであるから、請求の範囲またはその均等の範囲において種々の変更、置き換え、付加、省略などを行うことができる。 Note that the above-described embodiments are intended to exemplify the technology according to the present disclosure, and thus various changes, substitutions, additions, omissions, and the like can be made within the scope of the claims or equivalents thereof.
　本開示は、衣類乾燥機に適用可能である。具体的には、乾燥機、縦型洗濯乾燥機、ドラム式洗濯乾燥機などに、本開示は適用可能である。 The present disclosure is applicable to a clothes dryer. Specifically, the present disclosure is applicable to a dryer, a vertical washing dryer, a drum washing dryer, and the like.
