Further, each camber dividing plate 92 each site on its development length is along the tangent line of its bearing of trend and be acute angle through this site and the circumference concentric with the internal perisporium 902 of annular compartment 920 (circumference concentric with the internal perisporium 902 of annular compartment 920 in other words residing for this site) angle between the tangent line of this site in rotational direction A1 or be 0 ° of angle (in other words angle be less than 90 °) between the two.By such setting, when balance media can be made to rotate along direction of rotation A2, the resistance be subject in the process that the internal perisporium 902 from annular compartment 920 flows to periphery wall 901 is all less, thus shortens the time arriving periphery wall 901 further.
Particularly, see Figure 10, site 931 on camber dividing plate 92 has the tangent line S11 along its bearing of trend, site 931 is in on the concentric circumference C of gimbal 900, circumference C has the tangent line S22 along direction of rotation A1 at site 931 place, and the angle theta formed between tangent line S11 and tangent line S22 is acute angle or is 0 ° of angle.
In a preferred embodiment, in gimbal 900, the quantity of camber dividing plate 2 is 8-12, is preferably 10.In such embodiments, gimbal 900 is conducive to the diametrically position portion when rotary drum washing machine 100 spin-dry stage wash inner core 130 rotates, balance media being remained on maximum eccentric portion, thus effectively can suppress eccentric vibrating problem when slowly running.
Test shows, the gimbal of the radial dividing plate of the whole employings compared to existing technology, gimbal 900 of the present utility model can play balanced action when inner barrel of washing 130 rotating speed is relatively low.In other words, gimbal of the prior art just can play balanced action when needing the rotating speed of inner barrel of washing to reach certain rotary speed threshold value, and for the utility model embodiment, when the rotating speed of inner barrel of washing 130 is in the certain range of speeds lower than aforementioned rotary speed threshold value, gimbal 900 can play balanced action, thus makes can to carry out the spin-dry operation initial stage at its inner barrel of washing 130 according to the rotary drum washing machine 100 of the utility model embodiment and have less Oscillation Amplitude.
So far, those skilled in the art will recognize that, although multiple exemplary embodiment of the present utility model is illustrate and described herein detailed, but, when not departing from the utility model spirit and scope, still can directly determine or derive other modification many or amendment of meeting the utility model principle according to content disclosed in the utility model.Therefore, scope of the present utility model should be understood and regard as and cover all these other modification or amendments.
