The specific embodiment

Below in conjunction with picture specification specific embodiment of the present invention.But thought of the present invention is not limited on the suggested embodiment, and the colleague dealer who understands thought of the present invention can easily propose other embodiment in the same scope of the inventive concept.

Fig. 6 is the generalized section of hinge arrangement part under the barrel washing machine door open mode of the present invention.

As shown in Figure 6, the barrel washing machine door deformed configurations that prevents of the present invention includes: the circular rings 38 that forms in the periphery of drum door; The hinge axle 44 that on institute's allocation of circular rings 38, forms; The shell hinge axis 43 that on institute's allocation of shell 31 peripheries, forms; The two ends hinge is combined in the hinge bodies 42 on hinge axle 44 and the shell hinge axis 43; On circular rings 38 with hinge bodies 42 contacts site in depression be formed with groove 47; Extend to groove 47 and form the spring 48 of fixed platy morphology; Be formed with buffering projection 49 at the end of groove 47 medial surface protuberance.

Buffering projection 49 is the medial eminence formation at groove 47, and therefore, even hinge bodies 42 is run into door and made a distortion, the part of its distortion can not be observed from the outside.

Spring 48 extends to the part that can cover buffering projection 49, hinge bodies 42 can not directly be contacted, so can positively block the impulsive force of hinge bodies 42 with the bottom surface of groove 47.That is, door 36 is fully opened and when reaching hinge bodies 42 and run into the degree of groove 47, hinge bodies 42 is the end of contact spring 48 at first.Spring 48 is caused running on the buffering projection 49 by the thrust of hinge bodies 42.Circular rings 38 does not directly contact with hinge bodies 42, so just do not exist circular rings 38 to be caused the danger of being out of shape by hinge bodies 42 yet.

And when the power that Men Yigeng is strong was opened, spring 48 terminal parts that hinge bodies 42 is run into produced distortion, thus the impulsive force of available buffer hinge bodies 42.

When if the terminal part of spring 48 can not reach the top of buffering projection 49, under hinge bodies 42 and buffering projection 49 situations of directly running into, have only buffering projection 49 to be out of shape because of the impulsive force of hinge bodies 42.And buffering projection 49 be formed on detect by an unaided eye from the outside less than the inside portion of groove 47, so can not bring bad image to product yet.

Fig. 7 is the generalized section of hinge arrangement part under the roller washing machine door closure state of the present invention.

As Fig. 6, shown in Figure 7, open under the situation of door hinge bodies 42 the user and directly do not run into buffering projection 49, run in hinge bodies 42 under the state of spring 48 and see that spring 48 at first produces strain.

Spring 48 distortion is also run into buffering projection 49 is out of shape, thus the distortion of buffering projection 49 can not be by the user from visual observation to the advanced image that has improved product.

Fig. 8 is the local enlarged diagram of roller washing machine door hinge part of the present invention.

As shown in Figure 8, the door of roller washing machine of the present invention is formed with groove 47 at the outer peripheral face of circular rings 38, makes the opening action of hinge bodies 42 not overslaugh doors with this.Groove 47 is to be recessed to form with certain depth in the inboard of door.

Can find out for cushion the impulsive force that applies from hinge bodies 42, in the outstanding buffering projection 49 that is formed with of the medial surface of groove 47.

Not shown but prolong to the gap location of buffering projection 49 and hinge bodies 42 at the other end of an end (with reference to the figure 6) spring 48 of the position, institute bonding part of circular rings 38 inboards fixing spring 48 and to form, promptly the upside to buffering projection 49 prolongs formation, and the impulsive force that is added on the buffering projection 49 is obviously reduced.

As shown in the figure, the buffering projection 49 that forms in the outer peripheral face of barrel washing machine door itself is not arrived by visual observation, so, even 49 distortion of buffering projection can not from visual observation to.So, further improve the advanced image of product.

As shown in Figure 9, other parts of this embodiment are the same with last embodiment or similar.

Just cushioning the variant in shape of projection 49, the mid portion of the detailed buffering projection 49 of saying so protrudes and swells.So when opening door and spring 48 distortion, apply impulsive force for once the mid portion of buffering projection 49, and apply impulsive force for two side corner sections of buffering projection 49, or apply impulsive force no longer for after the cushioning effect through cushioning protruding 49 mid portions other part.So, can reduce the part of the generation distortion that is apparent in user perspective again.
