Inner barrel of washing 4 is like Fig. 4, Fig. 6～shown in Figure 8, has inner barrel of washing 4 is supported on the supporting base 44 on the outside of above-mentioned rear side base plate 31.Supporting base 44 usefulness aluminium die casting form, and have a plurality of support arms 45 of radial prolongation.Above-mentioned rotating shaft 43 is fixed on the center of supporting base 44.
Though above-mentioned rear side base plate 31 overall flat form to the inside the protrusion 46 of (front side of inner barrel of washing 4 to) protuberance with support arm 45 opposed position of above-mentioned supporting base 44.Be provided with lifter 47 interior week at cylindrical shell 30 with aliging with this protrusion 46.Protrusion 46 has and lifter 47 identical functions.
With regard to the raising of this washing capacity, remove beyond the cylindrical shell 30, comprise that the gimbal 33 of rear side base plate 31, front side reinforcing ring 32, ring-type, the various component parts and the parts that do not improve washing capacity of urceolus 5 do not have change and have general size.Thus, except the manufacturing equipment of relevant cylindrical shell 30 (for example molding die etc.), the manufacturing equipment before washing capacity improves can be used, changing significantly of manufacturing equipment and resetting of equipment needn't be carried out.
The cylindrical shell 30 of inner barrel of washing 4 has the rake 53 that tilts to peripheral direction at the position that carries out the transition to large-diameter portion 52 from minor diameter 50,51 recessedly.Rake 53 increases the rigidity of cylindrical shell 30.Only smooth inner barrel of washing is compared with there not being rake, also can bear the high speed dewatering rotation of 1700RPM on top.
The distolateral minor diameter 50 in front side has the length that axis of rotation direction width L1 conforms to the outer circumferential side height of gimbal 33.The distolateral minor diameter 51 of rear side needs axis of rotation direction width L2 at least.Axis of rotation direction width L2 is the length that conforms to the height of the axis of rotation direction of support arm 45.Thus, the width like distolateral minor diameter 51 such as the rear side shown in Fig. 4 waits then is axis of rotation direction width L2+ α.
The axis of rotation direction length of the large-diameter portion 52 that therefore, exists with the mode of the middle part scope of occupying cylindrical shell 30 is approximate with the length of having removed from the total length of cylindrical shell 30 behind axis of rotation direction width L1, the L2.
With regard to minor diameter 50, with regard to 51, though axis of rotation direction width L1, L2 smaller washing capacity are then high, it is necessary that the installation of gimbal 33 and support arm 45 combines.For the installation of fully guaranteeing gimbal 33 and support arm 45 combines, need axis of rotation direction width L1, L2.
In addition, distolateral minor diameter 50 places in the front side because interior all sides of the outer circumferential side of front side reinforcing ring 32 front side reinforcing ring 32 in the scope of axis of rotation direction width L1 and minor diameter 50 are chimeric, become firm so the front side of cylindrical shell 30 is distolateral.
At distolateral minor diameter 50 places of rear side, it is the part of the scope of axis of rotation direction width L2 that interior all sides of the outer circumferential side of rear side base plate 31 and minor diameter 51 are carried out chimeric, and terminates in the scope of crimping ca(u)lk part.Interior all sides of the outer circumferential side of rear side base plate 31 and minor diameter 51 part that only front end of support arm 45 is relative is chimeric in the scope of axis of rotation direction width L2.
Like this, the bottom surface through making rear side base plate 31 is near the rear end side of minor diameter 51, thereby the volume that can suppress inner barrel of washing 4 reduces.
Below, the manufacturing of washing content 4 is described.
The corrosion resistant plate of band shape is bent to the butted part at cylindric and welding two ends and forms cylindrical shell 30.The welding position forms along the axis of rotation direction of cylindrical shell 30.Afterwards, be processed to form distolateral minor diameter in front side 50 and the distolateral minor diameter 51 of rear side through pull and stretch. Minor diameter 50,51 is processed to form through the pull and stretch that dwindles to internal diameter direction.
Above-mentioned pull and stretch processing also can be used opposite pull and stretch processing and fabricating.That is expand and form large-diameter portion to outer circumferential side in the middle part that, also can weld butted part and make cylindrical shell 30.
On the cylindrical shell that is processed to form through pull and stretch 30, install and combination rear side base plate 31 and front side reinforcing ring 32.Through the crimping ca(u)lk rear side base plate 31 is combined on the minor diameter 51, and front side reinforcing ring 32 is combined on the minor diameter 50.Installation through rear side base plate 31 and front side reinforcing ring 32 combines, thereby cylindrical shell 30 is made indeformable firm macrostructure.
On front side reinforcing ring 32, embed gimbal 33, gimbal 44 is fastened on the front of cylindrical shell 30 with the outer circumferential side of the Screw 60 that is threaded from minor diameter 50.In the occasion that front side reinforcing ring 32 is not set, gimbal 33 directly is combined on the cylindrical shell 30.This occasion, in order to improve the rigidity of cylindrical shell 30 front, the strong especially gimbal of rigidity is used in expectation.
