【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、一般家庭用洗濯機に係り、特に静音化に好
適でしかも安全性・信頼性の高いモータ式排水弁機構を
備える洗濯機に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general household washing machine, and more particularly to a washing machine equipped with a motor type drain valve mechanism that is suitable for noise reduction and has high safety and reliability. .
従来、排水まで自動式タイプの洗濯機は、マグネツト
を用いて排水弁を開閉していたために、大きな衝撃音が
発生していた。近年、静音化のニーズが高まるにつれて
前述の如き衝撃を解消するためにモータ駆動式の排水弁
機構（特開昭62−299298号）が採用されるようになって
きた。Conventionally, a washing machine of an automatic type up to drainage uses a magnet to open and close the drain valve, which causes a loud impact noise. In recent years, as the need for noise reduction has increased, a motor-driven drain valve mechanism (Japanese Patent Laid-Open No. 62-299298) has come to be used in order to eliminate the impact as described above.
しかし、上記従来技術、例えばパネルボックス内の底
板にモータ本体を配設する方式では、水の侵入について
十分な配慮がされておらず、万一顧客が排水ホースを倒
し忘れた場合あるいは排水ホースが糸屑等で詰まった場

したりする恐れがあり、最悪焼損や感電の危険もあっ
た。However, in the above conventional technology, for example, the method of disposing the motor body on the bottom plate in the panel box, sufficient consideration is not given to water intrusion, and if the customer forgets to drop the drain hose or if the drain hose is If it is clogged with lint, etc., there is a risk that the motor body will be submerged in water due to overflow into the panel box, and in the worst case there is a risk of burnout or electric shock.
本発明の目的は、排水弁駆動用モータへの結露水の付
着を防止し、また万一顧客が排水ホースを倒し忘れた場
合あるいは排水ホースが糸屑等で詰まった場合であって
も、溢水とモータ本体とが触れることなく、電気的及び
絶縁的に有効な洗濯機を提供することにある。The object of the present invention is to prevent condensation water from adhering to the drain valve drive motor, and even if the customer forgets to drop the drain hose or if the drain hose is clogged with lint, etc. Another object of the present invention is to provide a washing machine that is effective electrically and electrically without touching the motor body.

内部に配設されている。An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, a motor pulley 4 is fixed to a washing motor 3 supported by a vibration-proof rubber 2 on a base 1, and a pulley 6 is driven by a V-belt 5 to be installed in an outer frame 7. The speed is reduced in the gear box portion 9 fixed to the bottom of the washing tub 8 to rotate the stirring blade 10 for washing. Also,
The operation panel 11 is provided with a controller 12 such as the washing motor 3 and a water level switch 13. Also, near the center,
An electromagnetic water supply valve 14 for supplying the water introduced by the water supply hose 15 into the washing tub 8 or the dehydration tub 16 is provided on the operation panel 11.
It is arranged inside.

されている。Now, when the user performs washing, the water supply hose 15 is connected to the electromagnetic water supply valve 14. Next, a desired washing water level is selected by the water level switching 13, and clothes are put into the washing tub 8. After that, by operating the control unit 12 in the operation panel 11, a valve opening command is transmitted from the control unit 12 such as a microcomputer to the electromagnetic water supply valve 14, and water is automatically supplied into the washing tub 8. When water is supplied to the designated water level position by the water level switch 13, although not shown, a pressure switch in the operation panel 11 gives a signal to stop the water supply, and then automatically starts washing. In addition, a drain valve driving motor (hereinafter referred to as a drain motor 17) is provided in the operation panel 11, and is connected to an internal pipe portion by a flexible connecting member 18.

る連結材18の移動距離はＳとなる。Now, in FIG. 2, when the washing is completed and the stage of the drainage stroke is reached, as shown in FIGS. 6 and 7, the drainage signal is output from the control unit 12, and the triac of 27 is turned on, When the neutral leaf 25 and the leaf a24 are connected (in the case of (I)), the drain motor 17 starts rotating, the cam 20 rotates, and at the same time, the connecting member 18 is pulled. As a result, the valve operating pipe 28 is pulled up, the associated valve body 32 and valve lip 33 are pulled up, and water flows out from the drain hose 35. Drainage motor 17
Is further rotated, and when the dowel 23 in the state detection switch 22 becomes the state (II) due to the step of the cam 20, the drain motor 17 is stopped, and the valve remains fully open. In this way, by using a synchronous motor with a small opening and closing of the valve, unlike the conventional magnet system, the valve can be opened and closed quietly without an impact noise. When the valve is closed, the connecting member 18 is loosened by the same cam rotation, and the spring 29 urges the valve lip 33 to stop the water. As shown in FIG. 3, the moving distance of the connecting member 18 due to opening and closing of the valve is S.

す恐れもある。Now, here, the drainage motor 17 is the panel box 30
It was usually installed on the inner bottom plate. However, in this case, if the customer forgets to drop the drain hose or if the drain hose is clogged with thread waste or the like, the drain motor 17 may be submerged due to an overflow accident. Further, if dew condensation water is generated, there is no escape route and the water will stay there, possibly causing insulation deterioration.
