（実施例）
以下、この発明による洗濯機の排水弁駆動装置の実施例
を図面を参照し、詳細に説明する。(Example) Hereinafter, an example of the drain valve driving device for a washing machine according to the present invention will be described in detail with reference to the drawings.
第１図はこの発明による洗濯機の排水弁駆動装置の一実
施例を示す断面図である。FIG. 1 is a sectional view showing an embodiment of a drain valve driving device for a washing machine according to the present invention.

のコイルボビン２ａ内に摺動自在に構成されている。That is, the cylindrical plunger 1, which is mechanically connected to a drain valve (not shown) via a wire 1a, is a direct current type! i stone 2
The coil bobbin 2a is configured to be slidable within the coil bobbin 2a.

引及び解放が行われる。A DC coil 2b is installed outside the coil bobbin 2a of the electromagnet 2.
is wound, and the plunger 1 is drawn into and released from the bobbin by switching ON-OFF current supply to the DC coil.

The impact surface of the yoke 2C and the inner surface of the bobbin 2a near the yoke 2C are coated with conductive silicone grease 3.

キ０Ｎ−ＯＦＦ動作が行われる。Therefore, the plunger 1 performs an adsorption-release operation in accordance with the 0N-OFF operation of the DC electromagnet 2, and the opening/closing control of the washing machine drain valve 5 and the brake 0N-OFF operation of the brake drum 6 connected to the rotary tub are performed. be exposed.

ク２Ｃへの衝突音が緩和され、騒音の低減がはかれる。When the plunger 1 is attracted to the yoke 2C by the operation of the electromagnet 2, the presence of the conductive silicone grease 3 alleviates the impact sound on the yoke 2C, thereby reducing noise.
この発明装置は、ヨーク２Ｃに塗布されたシリコーング

耐え得る良好な駆動装置が実現できたものである。In the device of this invention, the silicone grease 3 applied to the yoke 2C is made particularly conductive, thereby realizing a good drive device that can withstand long-term use.

た。In other words, if you simply apply general silicone grease and use it for a long period of time, the grease will gradually deteriorate due to changes over time such as the contamination of impurities such as dust and abrasion particles into the grease during the repeated adsorption and release of the plunger 1. A phenomenon of solidification occurs. The solidification of grease on the yoke surface prevents the plunger 1 from reaching the yoke surface during suction, preventing sufficient suction action, and at the same time, stopping at such an intermediate position may cause damage to the DC coil. A state where excessive excitation current continues to be supplied,
This caused a humming noise and even burnout of the coil.

発生やコイル焼損を防止できるものである。In contrast, in the present invention, since the silicone grease 3 itself has conductivity, even if it hardens, the conductivity between the plunger 1 and the yoke 2C is ensured, and the plunger 1 is electrically adhered to the yoke 2C. The condition is maintained, and the generation of whining noise and coil burnout can be prevented.

効果が確認された。Incidentally, when comparing the rate of increase in excitation current in an electromagnet when the applied silicone grease is not solidified during normal operation and when it is solidified, when conductive silicone grease is used, the increase is approximately 10 to 20% at most. However, when non-conductive silicone grease is used, the
The increase was 0 to 90%, confirming the effectiveness of conductive silicone grease.

果が得られる。Furthermore, in this embodiment, as a result of applying the conductive silicone grease 3 to the inside of the coil bobbin 2a, when the plunger 1 is released from suction and returns, the adhesive force of the grease moves.
The sliding friction noise at the time of release is softened, and the same noise reduction effect can be obtained.
