Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of outer barrel with slippery inner surface, with reference to Fig. 1, for the utility model has the rear outer barrel module inner schematic diagram of the outer barrel preferred embodiment of slippery inner surface, this outer barrel comprises front outer tub assembly 01 and rear outer tub assembly 10, this rear outer tub assembly 10 has smooth inner surface, this inner surface is provided with annular recess 11 in edge, for avoiding inner core distortion, as shown in Figure 5, the circular groove of annular recess 11 to be diameter along the cross section of rear outer tub assembly 10 axis be 10-40mm, the degree of depth of annular recess 11 is 2-10mm, the medial surface of outer tub assembly 01 before the mode that the outer ledge of annular recess 11 adopts circular arc to seamlessly transit connects.The cross section that the groove 11 of this embodiment is preferably along the axis of rear outer tub assembly 10 is arc-shaped, and its intensity is good and be easy to process, and also can be set to other shape as required.
Existing washing machine, reserved certain space between the bottom and the bottom of inner core of rear outer tub assembly, it is generally the distance of about 20mm, rear outer tub assembly is urged to prevent the bowing due to inner core, but this just causes washing machine structure compact not, and because headspace causes the distance between the bottom of the distance from bottom inner core of rear outer tub assembly comparatively large, just need more water when washing machine runs, and then cause the waste of water power.
The outer barrel with slippery inner surface that the present embodiment proposes, due to the setting of annular recess 11, the space between rear outer tub assembly 10 and inner core significantly reduces, and makes the compact conformation of washing machine, and then the water yield also corresponding minimizing needed during its operation, can water power be saved.
Further, with reference to shown in Fig. 2, Fig. 2 is the rear outer barrel module outer surface schematic diagram that the utility model has the outer barrel preferred embodiment of slippery inner surface.Outer surface 13 bottom rear outer tub assembly 10 distributes some reinforcements.Particularly, in the present embodiment, some reinforcements preferably comprise radial reinforced rib 14 and circumferential reinforcement 15, radial reinforced rib 14 is radially distributed to edge by the outer surface center of the bottom of rear outer tub assembly 10, circumference reinforcement 15 is the multi-turn ring stiffener coaxial with rear outer tub assembly 10, such distribution mode intensity is high, can guarantee that the service life intensity of rear outer tub assembly 10 can meet the requirement of 1400rpm, in other examples, reinforcement can be arranged to other distribution shape, the service life intensity of rear outer tub assembly 10 can be guaranteed.
Because existing outer barrel of washing machine is when designing, how be dislocatedly distributed in inside and outside both sides reinforcement, to ensure that the intensity of rear outer tub assembly can meet the requirement of Life Design.But because the existence of these muscle positions inside rear outer tub assembly, after Long-Time Service washing machine, locate easy residual soil in these muscle positions, thus after causing washing machine, outer tub assembly is dirty, and then causes the clothing washed to be secondary polluted, produce the hidden danger of health aspect.The utility model is only at the outer surface distribution reinforcement of rear outer tub assembly 10, and muscle position is optimized design, to ensure that the intensity of rear outer tub assembly 10 can meet Life Design requirement, rear outer tub assembly 10 inner surface is set to shiny surface, even if Long-Time Service, also can not be dirty at remained on surface, improve the overall performance of washing machine.
Further, the utility model proposes a kind of washing machine further, and this washing machine comprises inner core and has the outer barrel 10 of slippery inner surface as above, the shape of described inner surface and the form fit of inner core bottom surface.
Further, with reference to shown in Fig. 3 and Fig. 4, Fig. 3 is the sectional view of bearing block when clutch shaft bearing is in pre-determined bit state in the preferred embodiment of the utility model washing machine, and Fig. 4 is the sectional view of bearing block when clutch shaft bearing is in assembling completion status in the preferred embodiment of the utility model washing machine.This washing machine also comprises bearing block 20, clutch shaft bearing 30 and the second bearing 40, bearing block 20 comprises bearing block body 25, axis hole 26 is provided with in bearing block body 25, the both ends open place of axis hole 26 is respectively arranged with the clutch shaft bearing mounting groove 21 coaxial with axis hole 26 and the second bearing mounting groove 22, the openend of clutch shaft bearing mounting groove 21 is extended with the annular pre-determined bit portion 23 coaxial with clutch shaft bearing mounting groove 21 vertically, in the present embodiment, the length that annular pre-determined bit portion 23 is preferably in the axial direction is 2-20mm.The end face of the annular inwall in pre-determined bit portion 23 and the openend of clutch shaft bearing mounting groove 21 encloses pre-determined bit groove 24, the radius of pre-determined bit groove 24 is greater than the radius of clutch shaft bearing 30, and clutch shaft bearing 30 slides to clutch shaft bearing mounting groove 21 by pre-determined bit groove 24 along the axis of axis hole 26 under external force.
Due to existing washing machine bearing block when mounted, with pressing machine by bearing force fit bearing mounting groove, by bearing cone coarse positioning, bearing is when press-fiting into bearing block, the parallel press-in in outer ring can not be ensured, if bearing slightly tilts, also can be pressed into into bearing block, but the distortion on bearing enclose and bearing roller surface can be caused.The washing machine that the utility model proposes, the opening part of the clutch shaft bearing mounting groove 21 of its bearing block 20 is provided with coaxial pre-determined bit groove 23, ensure that clutch shaft bearing 30 can first vertically be put in pre-determined bit groove 23, realize the pre-determined bit of clutch shaft bearing 30, clutch shaft bearing mounting groove 21 is slowly pressed into again by press, to ensure in whole assembling process in clutch shaft bearing 30 parallel press-in clutch shaft bearing mounting groove 21, avoid clutch shaft bearing 30 press-in of tilting to cause the damage of bearing roller and bearing enclose.
Further, as shown in Figure 6, this washing machine also comprises oil sealing 50, the excircle radius in annular pre-determined bit portion 23 is less than the external diameter of bearing block body 25, oil sealing 50 is set in the outer surface in annular pre-determined bit portion 23 with sealed bearing 20, because annular pre-determined bit portion 23 is projecting relative to bearing block body 25, oil sealing 50 can be wrapped in the periphery of ledge, and its sealing effectiveness is better.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
