Description
この発明は、家庭用電気製品の筐体に関するものである。
The present invention relates to a housing for household electric appliances.
家庭用電気製品には、上下に長い縦型の筐体を持つものがある。従来において縦型の筐体を持つ家庭用電気製品として、例えば、筒状の送風部を有する本体と、この本体を支持する台座部とを有するタワー型の扇風機が知られている（例えば、特許文献１参照）。
Some household appliances have a long vertical casing. Conventionally, as a household electrical appliance having a vertical casing, for example, a tower-type electric fan having a main body having a cylindrical blower and a pedestal that supports the main body is known (for example, a patent) Reference 1).
特許文献１に示されるような従来における家庭用電気製品（タワー型の扇風機）の筐体は、プラスチック等を用いた樹脂成形品を用いることが一般的である。樹脂成形により特に縦長の筐体を製造する場合、射出成形では金型が大きくなってしまい製造費用が嵩んでしまう。一方、押出成形品は、両端部が刃物により切断されて製造されるため、両端面が切断面となり、いわゆるバリが出てしまう等の鋭利な箇所が残った状態となってしまう可能性がある。
In general, the housing of a conventional household electric product (tower fan) as shown in Patent Document 1 is a resin molded product using plastic or the like. In particular, when a vertically long casing is manufactured by resin molding, the mold becomes large in injection molding, and the manufacturing cost increases. On the other hand, since an extrusion molded product is manufactured by cutting both ends with a blade, there is a possibility that both end surfaces become cut surfaces, and sharp portions such as so-called burrs remain. .
この発明は、このような課題を解決するためになされたもので、縦長等の長尺な外形を持つものであっても、製造に大きな金型を必要とすることなく製造費用を低く抑えることが可能であって、かつ、製造時の切断面が鋭利な状態で残ってしまうことを抑制することができる家庭用電気製品の筐体を得るものである。
The present invention has been made to solve such a problem, and even if it has a long outer shape such as a vertically long shape, the manufacturing cost can be kept low without requiring a large mold for manufacturing. Therefore, it is possible to obtain a housing for household electric appliances that is capable of preventing the cutting surface from remaining in a sharp state at the time of manufacture.
この発明に係る家庭用電気製品の筐体においては、押出成形により製造され、側面に開口が形成され、軸線方向に直交する任意の箇所の断面の形状が同一である第１の部材と、射出成形により製造され、前記第１の部材の前記軸線方向の一端に固着され、一部が前記開口の一端側の縁部となる第２の部材と、射出成形により製造され、前記第１の部材の前記軸線方向の他端に固着され、一部が前記開口の他端側の縁部となる第３の部材と、を備えた構成とする。
In the housing for household electrical appliances according to the present invention, the first member manufactured by extrusion molding, having an opening formed on the side surface, and having the same cross-sectional shape at any location orthogonal to the axial direction, and injection A second member manufactured by molding, fixed to one end of the first member in the axial direction, and a part of which is an edge on one end side of the opening; and manufactured by injection molding, the first member And a third member that is fixed to the other end in the axial direction and a part of which is an edge portion on the other end side of the opening.
この発明に係る家庭用電気製品の筐体においては、縦長等の長尺な外形を持つものであっても、製造に大きな金型を必要とすることなく製造費用を低く抑えることが可能であって、かつ、製造時の切断面が鋭利な状態で残ってしまうことを抑制することができるという効果を奏する。
The housing for household electrical appliances according to the present invention can keep the manufacturing cost low without requiring a large mold for manufacturing, even if it has a long external shape such as a portrait. And there exists an effect that it can suppress that the cut surface at the time of manufacture remains in a sharp state.

この発明に係る家庭用電気製品の筐体が適用される家庭用電気製品として、ここでは、空気清浄機１を例に挙げて説明する。ただし、この発明が適用される家庭用電気製品は空気清浄機に限られない。なお、この発明の適用対象としては、特に上下に長い縦型の外形を持つ家庭用電気製品が好適である。
Here, as a household electrical product to which the housing of household electrical product according to the present invention is applied, the air cleaner 1 will be described as an example. However, household electric appliances to which the present invention is applied are not limited to air purifiers. Note that, as an application target of the present invention, a household electric product having a vertically long outer shape is particularly suitable.
図１に示すように、この発明の実施の形態１に係る家庭用電気製品の筐体が適用される空気清浄機１は、土台部１００、ダクト部２００及びキャップ部３００を備えている。土台部１００は、略直方体状を呈する。土台部１００の上面には、ダクト部２００が取り付けられている。ダクト部２００は中空筒状を呈する。ここでは、ダクト部２００は、中空な略円筒状である。なお、ダクト部２００の形状はこれに限られず、例えば中空の角柱状等でもよい。
As shown in FIG. 1, an air cleaner 1 to which a housing for household electric appliances according to Embodiment 1 of the present invention is applied includes a base part 100, a duct part 200, and a cap part 300. The base part 100 has a substantially rectangular parallelepiped shape. A duct unit 200 is attached to the upper surface of the base unit 100. The duct part 200 has a hollow cylindrical shape. Here, the duct part 200 is hollow and substantially cylindrical. In addition, the shape of the duct part 200 is not restricted to this, For example, a hollow prismatic shape etc. may be sufficient.
ダクト部２００は、土台部１００の上面から上方に向けて立つように設けられている。すなわち、ダクト部２００の長手方向は、土台部１００の上面に対し垂直に立てられている。ダクト部２００の上端には、キャップ部３００が取り付けられている。ダクト部２００の側面には、開口である吸込口（図示せず）が形成されている。吸込口は、ダクト部２００の背面側に長手方向にわたって配置されている。吸込口には、例えば、格子状の枠体にメッシュ状のプレフィルタが設けられた吸込口カバーが取り付けられている。
The duct part 200 is provided so as to stand upward from the upper surface of the base part 100. That is, the longitudinal direction of the duct part 200 is set up perpendicular to the upper surface of the base part 100. A cap unit 300 is attached to the upper end of the duct unit 200. A suction port (not shown) that is an opening is formed on the side surface of the duct part 200. The suction port is disposed over the longitudinal direction on the back side of the duct part 200. For example, a suction port cover in which a mesh-like prefilter is provided on a lattice-like frame is attached to the suction port.
また、ダクト部２００の内部には、空気清浄手段であるフィルタ（図示せず）が取り付けられている。このフィルタは、例えばＨＥＰＡ（Ｈｉｇｈ Ｅｆｆｉｃｉｅｎｃｙ Ｐａｒｔｉｃｕｌａｔｅ Ａｉｒ）フィルタである。土台部１００の一側面には、図示しない吹出口が形成されている。そして、土台部１００の内部には、図示しない送風ファン等が収容されている。
Also, a filter (not shown) that is an air cleaning means is attached to the inside of the duct portion 200. This filter is, for example, a HEPA (High Efficiency Particulate Air) filter. An air outlet (not shown) is formed on one side surface of the base portion 100. And the blower fan etc. which are not illustrated are accommodated in the base part 100. FIG.
図２から図４を参照しながら、ダクト部２００の構成についてさらに説明する。まず、図２に示すように、ダクト部２００は、第１の部材２１０、第２の部材２２０及び第３の部材２３０から構成されている。第１の部材２１０は、押出成形により製造された例えばプラスチック樹脂からなる。第２の部材２２０及び第３の部材２３０は、それぞれ、射出成形により製造された例えば同じくプラスチック樹脂からなる。
The configuration of the duct portion 200 will be further described with reference to FIGS. First, as shown in FIG. 2, the duct unit 200 includes a first member 210, a second member 220, and a third member 230. The first member 210 is made of, for example, a plastic resin manufactured by extrusion molding. The second member 220 and the third member 230 are each made of, for example, a plastic resin manufactured by injection molding.
図３に示すように、第１の部材２１０の側面には、前記吸込口となる開口２１１が形成されている。開口２１１は、第１の部材２１０の長手の全長にわたって形成されている。なお、第１の部材２１０の長手方向は、前記押出成形の押し出し方向である。以降においては、この押出成形の押し出し方向（ここでは、長手方向と同じ方向）のことを、「軸線方向」という。したがって、開口２１１について言い直せば、開口２１１は、第１の部材２１０の軸線方向の全長にわたって形成されている。
As shown in FIG. 3, an opening 211 serving as the suction port is formed on the side surface of the first member 210. The opening 211 is formed over the entire length of the first member 210. The longitudinal direction of the first member 210 is the extrusion direction of the extrusion molding. Hereinafter, the extrusion direction of the extrusion molding (here, the same direction as the longitudinal direction) is referred to as “axial direction”. Therefore, in other words, the opening 211 is formed over the entire length of the first member 210 in the axial direction.
第２の部材２２０は、第１の部材２１０の前記軸線方向の一端に固着されている。第２の部材２２０は、第１の部材２１０の前記軸線方向の一端面の全てを覆っている。第２の部材２２０の一部は、開口２１１の一端側の縁部になっている。
The second member 220 is fixed to one end of the first member 210 in the axial direction. The second member 220 covers the entire end surface of the first member 210 in the axial direction. A part of the second member 220 is an edge portion on one end side of the opening 211.
また、第３の部材２３０は、第１の部材２１０の前記軸線方向の他端に固着されている。第３の部材２３０は、第１の部材２１０の前記軸線方向の他端面の全てを覆っている。第３の部材２３０の一部は、開口２１１の他端側の縁部になっている。なお、ここでいう第１の部材２１０の端面（一端面及び他端面）とは、第１の部材２１０を構成するプラスチック樹脂の実体部分を指し、空間部分は含まない。
The third member 230 is fixed to the other end of the first member 210 in the axial direction. The third member 230 covers all of the other end surface of the first member 210 in the axial direction. A part of the third member 230 is an edge portion on the other end side of the opening 211. In addition, the end surface (one end surface and the other end surface) of the first member 210 referred to here refers to an actual part of the plastic resin constituting the first member 210 and does not include a space portion.
第２の部材２２０は、第１の部材２１０の一端面に超音波溶着により固着される。また、同様に、第３の部材２３０は、第１の部材２１０の他端面に超音波溶着により固着される。例えば接着剤を用いた場合には余分な接着剤が表面に出て意匠に悪影響を及ぼす可能性があるところ、このように各部材の固着に超音波溶着を用いることにより、そのような意匠上の悪影響を確実に避けることができる。
The second member 220 is fixed to one end surface of the first member 210 by ultrasonic welding. Similarly, the third member 230 is fixed to the other end surface of the first member 210 by ultrasonic welding. For example, when an adhesive is used, excess adhesive may come out on the surface and adversely affect the design. Thus, by using ultrasonic welding for fixing each member, The negative effects of can be surely avoided.
図３及び図４に示すように、第２の部材２２０には、ネジボス２２１が設けられている。ネジボス２２１は、ここでは、２箇所に設けられている。それぞれのネジボス２２１には、前記軸線方向の外側に向けてあけられたネジ穴が形成されている。そして、土台部１００は、これらのネジボス２２１を介して第３の部材２３０に固定されることにより、第１の部材２１０の前記軸線方向の他端側に取り付けられている。
As shown in FIGS. 3 and 4, the second member 220 is provided with a screw boss 221. Here, the screw bosses 221 are provided at two locations. Each screw boss 221 is formed with a screw hole that is drilled toward the outside in the axial direction. And the base part 100 is attached to the other end side of the first member 210 in the axial direction by being fixed to the third member 230 via these screw bosses 221.
すなわち、土台部１００の各ネジボス２２１に対向する位置にもネジ穴が貫通して設けられている。そして、土台部１００側のネジ穴を通されたネジを第２の部材２２０側のネジボス２２１のネジ穴に入れてネジを締めることで、土台部１００が第２の部材２２０に取り付けられる。こうして空気清浄機１の土台部１００とダクト部２００とが接続される。
That is, screw holes are also provided through the positions of the base portion 100 facing the screw bosses 221. Then, the base part 100 is attached to the second member 220 by inserting the screw passed through the screw hole on the base part 100 side into the screw hole of the screw boss 221 on the second member 220 side and tightening the screw. In this way, the base part 100 and the duct part 200 of the air cleaner 1 are connected.
なお、前述したようにダクト部２００は中空であり、ダクト部２００の内部には空間が形成されている。この空間に対応して第１の部材２１０及び第２の部材２２０にも、内側に空間が形成されているが、主に強度を確保して形状を保つために、第２の部材２２０には複数のリム２２２が設けられている。
As described above, the duct part 200 is hollow, and a space is formed inside the duct part 200. Corresponding to this space, the first member 210 and the second member 220 are also formed with a space inside, but in order to mainly maintain the strength and the shape, the second member 220 includes A plurality of rims 222 are provided.
図５は、第１の部材２１０の前記軸線方向に直交する断面の形状を示すものである。ここで、第１の部材２１０は、前述したように押出成形により製造されており、前記軸線方向に直交する任意の箇所の断面の形状が同一である。すなわち、第１の部材２１０の前記軸線方向の任意の箇所で直交するいずれの断面形状も、この図５に示す形状である。
FIG. 5 shows a cross-sectional shape of the first member 210 perpendicular to the axial direction. Here, the first member 210 is manufactured by extrusion as described above, and has the same cross-sectional shape at an arbitrary position orthogonal to the axial direction. That is, any cross-sectional shape of the first member 210 that is orthogonal at any point in the axial direction is the shape shown in FIG.
前述したように、第１の部材２１０の側面には、開口２１１が形成されている。ここでは第１の部材２１０は略円筒状であるため、断面の外形はこの開口２１１部分が欠けた略円弧状である。開口２１１は、この略円弧状の中心から見て角度αの範囲に形成されている。
As described above, the opening 211 is formed on the side surface of the first member 210. Here, since the first member 210 has a substantially cylindrical shape, the outer shape of the cross-section has a substantially arc shape with the opening 211 portion missing. The opening 211 is formed in the range of the angle α when viewed from the substantially arcuate center.
第１の部材２１０の内部には、第１の空間２１２が形成されている。この第１の空間２１２は開口２１１に通じている。第１の空間２１２は、開口２１１すなわち前記吸込口に通じる通風路となる。また、第１の部材２１０の内部には、さらに第２の空間２１３が形成されている。この第２の空間２１３は、仕切り壁２１４により第１の空間２１２から仕切られている。したがって、第２の空間２１３は、開口２１１に通じていない。
A first space 212 is formed inside the first member 210. The first space 212 communicates with the opening 211. The first space 212 serves as a ventilation path leading to the opening 211, that is, the suction port. Further, a second space 213 is further formed inside the first member 210. The second space 213 is partitioned from the first space 212 by a partition wall 214. Therefore, the second space 213 does not communicate with the opening 211.
前述したように、第１の部材２１０を備えたダクト部２００の下端には土台部１００が設けられ、上端にはキャップ部３００が設けられる。すなわち、土台部１００とキャップ部３００との間には、内部に第１の空間２１２及び第２の空間２１３が形成された第１の部材２１０が配置されている。ここで、土台部１００に設けられた電気部品とキャップ部３００に設けられた電気部品との間を電気的に接続する必要がある場合、これらの電気部品を接続する電気配線は、第１の空間２１２内ではなく、第２の空間２１３内を通すようにするとよい。
As described above, the base portion 100 is provided at the lower end of the duct portion 200 including the first member 210, and the cap portion 300 is provided at the upper end. In other words, the first member 210 in which the first space 212 and the second space 213 are formed is disposed between the base portion 100 and the cap portion 300. Here, when it is necessary to electrically connect the electrical component provided in the base part 100 and the electrical component provided in the cap part 300, the electrical wiring which connects these electrical parts is 1st. It is preferable to pass through the second space 213 instead of the space 212.
このようにすることで、開口２１１と通じており通風路になる第１の空間２１２内に電気配線を配置することなく、第１の部材２１０内に前記軸線方向にわたって電気配線を設けることができる。通風路になる第１の空間２１２内に電気配線を配置した場合には、第１の空間２１２内に発生する空気流により電気配線が動き、振動、騒音又は圧損等が発生するおそれがある。第１の空間２１２とは仕切られた第２の空間２１３を設け、この第２の空間２１３内に電気配線を配置することにより、このような振動、騒音又は圧損等の発生を回避することができる。
In this way, the electrical wiring can be provided in the first member 210 over the axial direction without arranging the electrical wiring in the first space 212 that communicates with the opening 211 and becomes a ventilation path. . When the electrical wiring is arranged in the first space 212 serving as a ventilation path, the electrical wiring moves due to the air flow generated in the first space 212, and vibration, noise, pressure loss, or the like may occur. By providing a second space 213 that is partitioned from the first space 212 and arranging electric wiring in the second space 213, occurrence of such vibration, noise, pressure loss, or the like can be avoided. it can.
また、第１の空間２１２と第２の空間２１３とを仕切る仕切り壁２１４を設けることで、第１の部材２１０の前記軸線方向に直交する断面における実体部分（樹脂部分）の断面積を増加させることができる。このため、第１の部材２１０の断面二次モーメントを増加して強度を増加させることも可能である。さらに、第１の部材２１０の前記軸線方向の両端部における実体部分（樹脂部分）の断面積を増加させることができるため、第１の部材２１０と第２の部材２２０又は第３の部材２３０との接着面積又は溶着面積を増加させ、接合強度を増すことにも寄与する。
In addition, by providing the partition wall 214 that partitions the first space 212 and the second space 213, the cross-sectional area of the substantial part (resin part) in the cross section orthogonal to the axial direction of the first member 210 is increased. be able to. For this reason, it is also possible to increase the strength by increasing the second moment of section of the first member 210. Furthermore, since the cross-sectional area of the substantial part (resin part) at both ends in the axial direction of the first member 210 can be increased, the first member 210 and the second member 220 or the third member 230 This increases the bonding area or welding area of the film and contributes to increasing the bonding strength.
なお、主に意匠上の観点から、第１の部材２１０の外周面にシート状部材を設けるようにしてもよい。この場合、第１の部材２１０の前記軸線方向に直交する投影面上において、第２の部材２２０及び第３の部材２３０の外形を、少なくとも前記シート状部材の厚み分だけ第１の部材２１０の外形よりも大きくすることが望ましい。
Note that a sheet-like member may be provided on the outer peripheral surface of the first member 210 mainly from the viewpoint of design. In this case, on the projection plane orthogonal to the axial direction of the first member 210, the outer shape of the second member 220 and the third member 230 is at least as much as the thickness of the sheet-like member. It is desirable to make it larger than the outer shape.
このようにすることで、特に、第１の部材２１０と、第２の部材２２０又は第３の部材２３０との接合部分において、前記シート状部材の端部が第２の部材２２０又は第３の部材２３０よりも外方に出ることがない。よって、前記シート状部材の端部が第１の部材２１０の表面から剥れてめくれ上がることを防止することができ、外観上の見た目が悪くなることを避けることが可能である。
In this way, in particular, at the joint portion between the first member 210 and the second member 220 or the third member 230, the end of the sheet-like member is the second member 220 or the third member. It does not go out beyond the member 230. Therefore, it can prevent that the edge part of the said sheet-like member peels off from the surface of the 1st member 210, and it can avoid that the external appearance looks worse.
以上のように構成された家庭用電気製品の筐体は、押出成形により製造され、側面に開口２１１が形成され、軸線方向に直交する任意の箇所の断面の形状が同一である第１の部材２１０と、射出成形により製造され、第１の部材２１０の前記軸線方向の一端に固着され、一部が開口２１１の一端側の縁部となる第２の部材２２０と、射出成形により製造され、第１の部材２１０の前記軸線方向の他端に固着され、一部が開口２１１の他端側の縁部となる第３の部材２３０と、を備えたものである。
The household electrical appliance casing configured as described above is manufactured by extrusion molding, has an opening 211 formed on a side surface, and a first member having the same cross-sectional shape at an arbitrary position orthogonal to the axial direction. 210, manufactured by injection molding, fixed to one end of the first member 210 in the axial direction, a part of which is an edge on one end side of the opening 211, and a second member 220 manufactured by injection molding, The third member 230 is fixed to the other end of the first member 210 in the axial direction, and a part of the third member 230 is an edge of the opening 211 on the other end side.
このため、縦長等の長尺な外形を持つものであっても、長尺な部分を押出成形により製造することで、製造に大きな金型を必要とすることなく製造費用を低く抑えることが可能である。しかも、製造時の押出成形による切断面となる両端に、射出成形で製造した部材を固着することにより、押出成形による切断面が鋭利な状態で残ってしまい外部に露出することを抑制することができる。
For this reason, even if it has a long outer shape such as vertically long, manufacturing costs can be kept low without requiring a large mold for manufacturing by manufacturing the long part by extrusion molding. It is. Moreover, it is possible to prevent the cut surface by extrusion molding from remaining in a sharp state and being exposed to the outside by fixing the members manufactured by injection molding to both ends which are cut surfaces by extrusion molding at the time of manufacture. it can.
また、押出成形品は必然的に一定の断面形状となるため、筐体の側面に開口を設ける場合に後から別途開口を形成する必要があるところ、上記の構成によれば、後から別途開口を形成することなく、筐体の側面に開口を容易に設けることができる。
In addition, since the extruded product has a constant cross-sectional shape, it is necessary to form a separate opening later when providing an opening on the side of the housing. The opening can be easily provided on the side surface of the housing without forming the.
さらに、第２の部材２２０は、第１の部材２１０の前記軸線方向の一端面を全て覆い、第３の部材２３０は、第１の部材の前記軸線方向の他端面を全て覆うようにすることで、押出成形による切断面を全て射出成形品で覆い、切断面が外部に露出することを完全に防止することができる。
Further, the second member 220 covers all the one end surface of the first member 210 in the axial direction, and the third member 230 covers all the other end surface of the first member in the axial direction. Thus, it is possible to completely prevent the cut surface from being exposed to the outside by covering the entire cut surface by the extrusion molding with the injection molded product.
加えて、第２の部材２２０にネジ穴が形成されたネジボス２２１を設け、このネジボス２２１を介して第２の部材２２０に固定することにより、第１の部材２１０の前記軸線方向の他端側に土台部１００を取り付けるようにすることで、筐体の筒状縦長な部分（第１の部材２１０）を支える土台部１００を当該部分（第１の部材２１０）に直接に取り付ける場合と比較して、容易に当該部分（第１の部材２１０）の一端側に土台部１００を取り付けることができ、組立性を良好なものにすることが可能である。
In addition, the second member 220 is provided with a screw boss 221 having a screw hole formed therein, and is fixed to the second member 220 via the screw boss 221 so that the other end side of the first member 210 in the axial direction. Compared with the case where the base part 100 that supports the cylindrical vertically long part (first member 210) of the housing is directly attached to the part (first member 210) by attaching the base part 100 to the base part. Thus, the base portion 100 can be easily attached to one end side of the portion (the first member 210), and the assemblability can be improved.
この発明は、例えば縦長等の長尺な外形を持つ家庭用電気製品の筐体に利用できる。
The present invention can be used for a housing of a household electric product having a long external shape such as a portrait.
