[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.
[0021] See also Figure 1 and Figure 2The embodiment of the utility model discloses an outer barrel device for a drum washing machine, comprising a barrel body 1 and a bearing seat 2, wherein the barrel body 1 is the outer barrel of the washing machine, and the barrel body 1 is connected to the inner barrel through the bearing seat 2. A bottom plate 11 is provided at the bottom of the barrel body 1, a receiving hole 111 is provided in the middle of the barrel body 11, a bearing mounting column 21 is provided in the middle of the bearing seat 2, and the bearing mounting column 21 can be inserted into the receiving hole 111, thereby forming an assembly fixation, and the bearing is mounted in the inner hole of the bearing mounting column 21. In order to improve the strength of the bearing seat 2, a reinforcing rib 22 is provided in the middle part of the bearing seat 2, and the reinforcing rib 22 surrounds the outer side of the bearing mounting column 21 to reinforce the bearing mounting column 21. Traditional reinforcing ribs 22 are complete annular structures, but this complete annular structure will hinder the liquid plastic from entering the inner ring of the reinforcing rib 22 during injection molding to form the bearing mounting column 21. The bearing mounting column 21 formed in this way will produce defects such as deformation, shrinkage, warping and flanging. Once these defects occur, it is easy to cause the bearing mounting column 21 and the receiving hole 111 to be assembled, which is easy to produce a single force fulcrum, different sizes of fitting clearances, uneven force, etc., thereby greatly reducing the fitting stability between the bearing mounting column 21 and the receiving hole 111. In the embodiment of the utility model, in order to allow the liquid plastic to flow freely, a plurality of notches 221 are spaced apart in the reinforcing rib 22, and the notches 221 are recessed downward from the upper surface of the reinforcing rib 22, so that the liquid plastic can enter the position of the bearing mounting column 21 through the notches 221, so as to ensure that the bearing mounting column 21 can be formed normally, thereby reducing the occurrence of the single force fulcrum, the uneven size of the matching gap, the uneven force, etc., and improving the matching stability between the bearing mounting column 21 and the receiving hole 111. In addition, a receiving groove 112 is also provided in the middle of the bottom plate 11, and the receiving groove 112 surrounds the outer side of the receiving hole 111, and the reinforcing rib 22 can be inserted into the receiving groove 112, and the matching between the reinforcing rib 22 and the receiving groove 112 can limit the bearing mounting column 21, thereby stabilizing the matching between the bearing mounting column 21 and the receiving hole 111.
