【発明の属する技術分野】
この発明は、洗濯行程の次に乾燥行程を設けた洗濯乾燥機に関するものである。
【0002】
【従来の技術】
洗濯兼脱水槽内の洗濯物に温風を接触させて洗濯物を乾燥させる乾燥行程を設けた洗濯乾燥機の一例として、外箱と外箱の上部に配設するトップカバーと、外箱内に配設する洗濯槽と、前記洗濯槽内に温風を供給する温風供給手段を備えた洗濯乾燥機において、前記トップカバーの後部位置に前記温風供給手段の加熱装置を配設し、この加熱装置からの温風を洗濯槽に導入する温風吐出ダクトをトップカバーの内側にそって配置したものである(例えば、特許文献1参照)。
【0003】
そして、洗濯兼脱水槽内の洗濯物を乾燥させるには、温風供給手段の加熱装置であるヒータに通電し、別途配設した送風機を作動して加熱装置で加熱した温風を温風吐出ダクトを介して洗濯兼脱水槽内に送っている。
【0004】
【特許文献1】
特開2001−198385号公報
【0005】
【発明が解決しようとする課題】
洗濯兼脱水槽内に温風を供給するための手段として、加熱装置を設置しているが、この加熱装置は室温の空気を衣類を乾燥できる程度の温風になるまで加熱するものであり、比較的大きな容量を必要とし、また、所定温度にまで加熱するには時間とコストを要する。
【0006】
一方、洗濯乾燥機には、洗濯兼脱水槽を回転駆動させるためのモータが備わっており、このモータからは駆動より排熱が発生しているが、これは利用されることなく冷却用のファンで排気されている。
【0007】
また、温風を洗濯兼脱水槽内に送るには専用の送風ファンを設置しているので、部品点数が多くなり、構造も複雑となる。
【0008】
この発明の目的は前記従来例の不都合を解消し、洗濯乾燥機において、洗濯兼脱水槽内に温風を供給するに際し、送風用のファンを別途格別に設置する必要がなく、部品点数の削減と構造の簡素化を図ることができ、また、加熱装置を設ける場合であっても容量を小さくできて省エネとコストダウンを図ることができる洗濯乾燥機を提供することにある。
【0009】
【課題を解決するための手段】
この発明は前記目的を達成するため、外箱内に洗濯兼脱水槽を回転自在に配設し、この洗濯兼脱水槽に駆動用のモータを接続した洗濯乾燥機において、前記モータに付設した送風ファンに一端が連通する送風ダクトを洗濯兼脱水槽の上部に開口することを特徴とする。
【0010】
これにより、モータからの排熱を利用してこの熱で空気を加熱し、温風として洗濯兼脱水槽内に供給すれば、ランニングコスト低減を図れる。また、温風を洗濯兼脱水槽に送る手段としてモータに付設の冷却用の送風ファンを利用すれば、送風用のファンを別途設置する必要がなく、部品点数を減少でき、構造が複雑になることもなく、省エネも図れる。
【0011】
【発明の実施の形態】
以下、図面についてこの発明の実施の形態を詳細に説明する。図1は、この発明の洗濯乾燥機の第1実施形態を示す縦断側面図で、上面に洗濯物の出入用の開口を設けた全自動1槽式洗濯機であり、全体構成から説明すると、外箱1内に水槽2を防振装置を介して揺動自在に吊支し、この水槽2内に底部に回転翼4を設けた洗濯兼脱水槽3を回転自在に配設したもので、前記水槽2の上端縁には、洗濯兼脱水槽3の上部の開口縁に取り付けたバランサ6の上方を覆うようにして水槽カバー5が取り付けてある。
【0012】
外箱1の上部には、水槽カバー5の上方を覆うようにして蓋7を設けたトップカバー8が配設され、蓋7には吸気口7aが形成されている。
【0013】
水槽2の底部の下方に、モータ9を配設し、このモータ9から下方に向けて突出する駆動軸にプーリ10aと一体の冷却用の送風ファン10を結合し、同じく水槽2の底部の下方に配設した減速機構11の回転軸に連結したプーリ12とをベルト13で連結した。
【0014】
水槽2の底部に排水口を形成し、この排水口に、途中に排水弁15を設けた排水管14を開口する。
【0015】
かかる構成の洗濯乾燥機において、前記送風ファン10をファンケーシング16で覆い、このファンケーシング16に一端を開口する送風ダクト17を水槽2の外壁にそって立ち上げ、この送風ダクト17の上端を水槽カバー5の開口縁に開口する。
【0016】
送風ダクト17は、水槽2に沿ってこれと平行に立上がる箇所では、水槽2の外壁をダクト壁と共用し、水槽2の外壁で送風ダクト17の一部を構成する。また、送風ダクト17の上部の開口17aも水槽カバー5の開口縁で開口17aの一部を構成する。
【0017】
そして、送風ダクト17の内部に加熱手段としてのヒータ18を配設する。
【0018】
次に作用について説明する。乾燥行程でモータ9に通電すれば、モータ冷却用の送風ファン10が回転し、モータ9の排熱により暖められた空気が温風として送風ファン10により送風ダクト17を介して上方の開口17aに送られ、ここから洗濯兼脱水槽3内に送風され、洗濯兼脱水槽3内の洗濯物に当てられる。
【0019】
この場合、モータ9の排熱だけでは洗濯物を乾燥させるに十分な熱量が得られないので、送風ダクト17の途中に設けたヒータ18に通電してヒータ18でさらに加熱する。
【0020】
また、モータ9が回転することでこれが振動するが、送風ダクト17もモータ9が固定されている水槽2に固定されているから、モータ9の振動が送風ダクト17に悪影響を及ぼすことはない。
【0021】
図2は第2実施形態を示し、これは回転ドラム式の洗濯乾燥機であり、前部に衣類の出し入れ用の扉23を設けた外箱20内に配設した水槽となるケーシング21の内部に洗濯兼脱水槽となる回転ドラム22を軸着したもので、回転ドラム22およびケーシング21の背面側には吸気口31が形成され、前面側には排気口32が形成されている。
【0022】
前記ケーシング21の底部の下方に位置させてモータ24を外箱20に固定し、このモータ24の回転駆動軸に送風ファン25と一体のプーリ29を取り付け、このプーリ29を回転ドラム22の回転軸に取り付けたプーリ28とベルト30で連結する。
【0023】
前記送風ファン25をファンケーシング26で覆い、このファンケーシング26に一端を開口する送風ダクト27を外箱20の内壁にそって立ち上げ、この送風ダクト27の上端を吸気口31に開口する。
【0024】
送風ダクト27は、外箱20に沿ってこれと平行に立上がる箇所では、外箱20の内壁面に密着させる。
【0025】
乾燥行程で回転ドラム22内の衣類を乾燥するには、モータ24に通電すれば、モータ冷却用の送風ファン25が回転し、モータ24の排熱により暖められた空気が温風として送風ファン25により送風ダクト27を介して上方の吸気口31に送られ、ここから回転ドラム22内に送風され、内部の洗濯物に当てられる。これにより、洗濯物が乾燥する。
【0026】
また、モータ24が回転することでこれが振動するが、送風ダクト27もモータ24が固定されている外箱20に固定されているから、送風ダクト27のモータ24に追随して振動するから、モータ24の振動が送風ダクト27に悪影響を及ぼすことはない。
【0027】
【発明の効果】
以上述べたようにこの発明の洗濯乾燥機は、外箱内に洗濯兼脱水槽を回転自在に配設し、この洗濯兼脱水槽に駆動用のモータを接続した洗濯乾燥機において、前記モータに付設した送風ファンに一端が連通する送風ダクトを洗濯兼脱水槽の開口部側あるいは開口部とは反対側に開口するようにした。
【0028】
これにより、モータからの排熱を利用してこの熱で空気を加熱し、温風として洗濯兼脱水槽内に供給すれば、加熱のためのランニングコスト低減を図れる。また、温風を洗濯兼脱水槽に送る手段としてモータに付設の冷却用の送風ファンを利用すれば、送風用のファンを別途設置する必要がなく、部品点数の減少を図ることができ構造が複雑になることもなく、省エネも図れるものである。

[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a vertical sectional side view showing a first embodiment of a washing / drying machine of the present invention, which is a fully automatic one-tub washing machine having an opening for entry and exit of laundry on an upper surface. A water tub 2 is swingably suspended in an outer box 1 via a vibration isolator, and a washing and dewatering tub 3 having a rotating blade 4 at the bottom is rotatably arranged in the water tub 2. A water tank cover 5 is attached to an upper edge of the water tank 2 so as to cover an upper part of a balancer 6 attached to an upper opening edge of the washing and dewatering tank 3.
[0012]
A top cover 8 provided with a lid 7 is provided on the upper part of the outer box 1 so as to cover the upper part of the water tank cover 5, and the lid 7 is formed with an air inlet 7a.
[0013]
A motor 9 is provided below the bottom of the water tank 2, and a cooling fan 10 integrated with a pulley 10 a is coupled to a drive shaft projecting downward from the motor 9. And a pulley 12 connected to a rotating shaft of a speed reduction mechanism 11 disposed at the same position by a belt 13.
[0014]
A drain port is formed at the bottom of the water tank 2, and a drain pipe 14 provided with a drain valve 15 on the way is opened at the drain port.
[0015]
In the washing / drying machine having such a configuration, the blower fan 10 is covered with a fan casing 16, and a blower duct 17 having one end opened in the fan casing 16 is set up along the outer wall of the water tub 2. An opening is provided at the opening edge of the cover 5.
[0016]
When the air duct 17 rises along the water tank 2 in parallel with the water tank 2, the outer wall of the water tank 2 is shared with the duct wall, and the outer wall of the water tank 2 forms a part of the air duct 17. The opening 17a at the top of the air duct 17 also forms part of the opening 17a at the opening edge of the water tank cover 5.
[0017]
Then, a heater 18 as a heating means is disposed inside the blower duct 17.
[0018]
Next, the operation will be described. When the motor 9 is energized during the drying process, the blower fan 10 for cooling the motor rotates, and the air heated by the exhaust heat of the motor 9 is heated by the blower fan 10 to the upper opening 17a through the blower duct 17 as warm air. The air is sent to the washing and dewatering tub 3 and is then blown to the laundry in the washing and dewatering tub 3.
[0019]
In this case, since the amount of heat sufficient to dry the laundry cannot be obtained only by the exhaust heat of the motor 9, the heater 18 provided in the middle of the ventilation duct 17 is energized and further heated by the heater 18.
[0020]
In addition, the vibration of the motor 9 is caused by the rotation of the motor 9. However, since the blower duct 17 is also fixed to the water tank 2 to which the motor 9 is fixed, the vibration of the motor 9 does not adversely affect the blower duct 17.
[0021]
FIG. 2 shows a second embodiment, which is a rotary drum type washing / drying machine, in which a casing 21 serving as a water tank is disposed in an outer box 20 provided with a door 23 for taking in and out clothes at the front. A rotary drum 22 serving as a washing and dewatering tub is pivotally mounted on the rotary drum 22. An intake port 31 is formed on the back side of the rotary drum 22 and the casing 21, and an exhaust port 32 is formed on the front side.
[0022]
A motor 24 is fixed to the outer case 20 at a position below the bottom of the casing 21, and a pulley 29 integral with the blower fan 25 is attached to a rotation drive shaft of the motor 24. Is connected to a pulley 28 attached to the belt by a belt 30.
[0023]
The blower fan 25 is covered with a fan casing 26, and a blower duct 27 having one end opened in the fan casing 26 is set up along the inner wall of the outer box 20, and the upper end of the blower duct 27 is opened to the intake port 31.
[0024]
The air duct 27 is brought into close contact with the inner wall surface of the outer case 20 at a position where it rises along the outer case 20 in parallel with the outer case 20.
[0025]
In order to dry the clothes in the rotating drum 22 during the drying process, when the motor 24 is energized, the blower fan 25 for cooling the motor rotates, and the air warmed by the exhaust heat of the motor 24 becomes hot air and becomes the blower fan 25. Thus, the air is sent to the upper intake port 31 through the air duct 27, and is blown into the rotating drum 22 from there, and hits the laundry inside. Thereby, the laundry is dried.
[0026]
In addition, the motor 24 rotates to vibrate, but the blower duct 27 is also fixed to the outer box 20 to which the motor 24 is fixed. The vibration of 24 does not adversely affect the air duct 27.
[0027]
【The invention's effect】
As described above, in the washing / drying machine of the present invention, in the washing / drying machine in which the washing and spin-drying tub is rotatably arranged in the outer box and a driving motor is connected to the washing and spin-drying tub, A blow duct, one end of which is connected to the attached blower fan, is opened on the opening side of the washing and dewatering tub or on the side opposite to the opening.
[0028]
Thus, if the air is heated using the exhaust heat from the motor and supplied as warm air into the washing and dewatering tub, the running cost for heating can be reduced. In addition, if a cooling fan attached to the motor is used as a means for sending warm air to the washing and dewatering tub, there is no need to separately install a fan for air blowing, and the number of parts can be reduced and the structure can be reduced. It does not become complicated and can save energy.
