In the washing machine course of work, inner core rotates in urceolus, have water droplet or current and flow to rotating shaft and sealing device along urceolus rear wall inner surface, and in can the stopping on the one hand and rush at the current of sealing device end face and prevent that these current from flowing through sealing device and sealing mutually with rotating shaft the face contacting towards water conservancy diversion lip is set on inner core end face of sealing device, avoid grease between sealing device and rotating shaft to be subject to the corrosion of these current; Can guide shunting away from sealing device to current on the other hand.
As further improvement of the utility model, described end face around described rotating shaft setting and ringwise.
As further improvement of the utility model, described water conservancy diversion lip be arranged at described end face position, inside edge and or outer edge position.
This water conservancy diversion lip can be arranged at the inside edge of close rotating shaft on sealing device end face or the outer edge away from rotating shaft, can certainly water conservancy diversion lip be set on interior outer edge position to play the effect of better obstruct water simultaneously.
As further improvement of the utility model, taking longitudinal direction as benchmark, described water conservancy diversion lip at least distributes and is positioned on the described end face of described rotating shaft top, for the current that at least shunting is flowed from the top down.
It is all because gravity is former thereby stream from top to down that the overwhelming majority rushes at current that sealing device and rotating shaft seal the face contacting mutually, can better play so distribution water conservancy diversion lip is set on the sealing device end face above rotating shaft the function that intercepts current.
As further improvement of the utility model, the curved shape of described water conservancy diversion lip and being arranged on described end face.
Water conservancy diversion lip is one section of arc shape and is arranged on the sealing device end face above rotating shaft, can in very large range intercept the current that flow from the top down and rush at the sealing contact surface of rotating shaft and sealing device.
As further improvement of the utility model, described water conservancy diversion lip is arranged on described end face around described rotating shaft.
So, water conservancy diversion lip can intercept the current of the sealing contact surface that rushes at rotating shaft and sealing device in a circumference range.
As further improvement of the utility model, described water conservancy diversion lip is arranged on described end face ringwise.
As further improvement of the utility model, described water conservancy diversion clypeus is originally laterally vertically installed on described end face.
