When impeller 16 in alternating direction rotation when realizing the agitator treating process, this wind spring 46 is prevented from stoping by friction element 48 and these jut 17 inner circumferential surface CONTACT WITH FRICTION simultaneously by friction element 49 and flexible member installing ring 44 and 42 and the external peripheral surface CONTACT WITH FRICTION of annular shim 43.Therefore, increased the durability of clutch coupling of washing machine device, vibrations and noise reduce simultaneously.
After the washing of finishing washing machine or rinsing operation, start the dehydrating operations of washing machine.When wash shaft 24 continued in the rotation of direction, this wind spring 46 at utmost extended, and the result is delivered to dehydrating shaft 22 from the revolving force of wash shaft 24, and like this, cylindric washer 14 also rotates, and normally realizes the dehydrating operations of washing machine.
In above-mentioned the 5th embodiment of the present invention, by friction element 48 and friction element 49 are provided, improved the connection between dehydrating shaft 22 and wash shaft 24, therefore, improved the efficient that revolving force transmits.
Find out obviously that from top description the present invention has following effect.
The clutch coupling of washing machine device of first or second preferred embodiment comprises helical spring according to the present invention, and this spring and wash shaft and dehydrating shaft CONTACT WITH FRICTION are used for the revolving force from wash shaft is delivered to dehydrating shaft.Therefore, the present invention has the advantage that makes the clutch apparatus general structure simplify and reduce this clutch apparatus manufacturing cost.
In addition, the clutch coupling of washing machine device of first or second preferred embodiment comprises friction element according to the present invention, in dewatering operation of washing machine, this friction element is used to reduce owing between helical spring and the dehydrating shaft and the wearing and tearing that cause of the friction between helical spring and wash shaft.Therefore, the present invention has the effect that improves the clutch apparatus durability, reduces the noise that produces in the clutch apparatus and vibrations and improve clutch apparatus revolving force transmission efficiency.
The clutch coupling of washing machine device of the 3rd or the 4th preferred embodiment comprises the spring fixed part according to the present invention, wherein this spring fixed part is a hollow cylindrical, be used to make the frictional force maximization that produces between spring fixed part and friction element, a wherein helical spring end is fixedly attached on this spring fixed part.Therefore, the present invention has the effect that can reduce the clutch apparatus parts produce when wash shaft is rotated together along with dehydrating shaft wearing and tearing, noise and vibrations effectively.
Clutch coupling of washing machine device according to fifth preferred embodiment of the invention comprises friction element, this element the flexible member installing ring and annular shim external peripheral surface and helical spring between, be used to stop the external peripheral surface CONTACT WITH FRICTION of helical spring and flexible member installing ring and annular shim.Therefore, the present invention has the effect that improves the clutch apparatus durability and reduce clutch apparatus generation noise and vibrations.
Although for the purpose that illustrates has disclosed the preferred embodiments of the present invention, it will be appreciated by persons skilled in the art that not breaking away under the invention scope and mental condition that in the accessory claim book, discloses, can carry out various remodeling, interpolation and replacement.
