The specific embodiment
One embodiment of the present of invention are described with reference to the accompanying drawings.It is pointed out that general technical thought of the present invention is not subjected to the qualification of this embodiment.
Fig. 1 is that the tumbling-box washing machine in one embodiment of the present of invention is in the oblique view under the lid open mode, Fig. 2 is the front view of the primary structure around the expression coupling component, when Fig. 3 is in closed condition for lid along the sectional view of the B-B line among Fig. 2, along the sectional view of the B-B line among Fig. 2, Fig. 5 was the longitudinal section of whole machine body when Fig. 4 was in open mode for lid.In addition, among Fig. 5 with existing apparatus in identical component parts put on identical symbol, and omit being repeated in this description to this.In addition, because identical in the sequence of operations of washing, rinsing, dehydration etc. and the existing apparatus, so also omitted narration to these operating process.
As shown in Fig. 2 to Fig. 4, the front portion is provided with on the washing machine body 32 of opening portion 31 rotating shaft support unit 33 is installed, be located at two rotations coupling component 35,36 freely is installed on the rotating shaft 34 in this rotating shaft support unit 33, and by the mounting portion on it 37,38 and open and close the lid 39 block opening portion 31 freely and link.It is the circular shape in the center of circle that above-mentioned two coupling components 35,36 roughly are with rotating shaft 34, and as shown in fig. 1, each other from becoming big more by arc radius far away more.Particularly, if establishing the arc radius of immediate each other circular arc portion 40,41 on the width of coupling component 35,36 is R1, be R2 from the arc radius that gets arc sections 42,43 farthest each other, then be the relation of R1＜R2 between R1, the R2.In addition, rotating shaft 34 is provided with the spring 44 that can apply elastic force, coupling component 35,36 is always imposed on point to the elastic force of opening direction, to prevent that lid 39 from being shut suddenly.
The front portion of washing machine body 32 is equipped with preceding frame member 45, and in addition, the place ahead of the opening portion 31 of washing machine body 32 is equipped with cover plate 46 in the form of a ring.As shown in fig. 1, this cover plate 46 is provided with two narrow slits 47,48 that supply coupling component 35,36 to pass, and makes lid 39 opening/closing successfully.Fig. 2 does not illustrate parts such as lid 39, preceding frame member 45, cover plate 46, is in two coupling components 35,36 under the closed condition and show lid 39.
Around the opening portion 31 of washing machine body 32 roughly tubular seal member 49 is housed, seal member 49 is fixed on the washing machine body 32 by seal installing plate 50.Be under the closed condition at lid 39, the seal member 49 outside being installed on the opening portion 14 of bucket 3 withstands the inner cap 51 that clear glass is made as shown in Figure 3, makes the opening portion 31 on the washing machine body 32 keep the watertight states; In addition, seal member 49 in dewatering operation course, also have do one's utmost to prevent outside the anti-vibration functions of bucket 3 vibration transfer to the washing machine body 32.
The working condition and the effect of the coupling component 35,36 with above-mentioned structure are described below.After adopting above-mentioned structure, because it is also just big more between two coupling components 35,36 at a distance of its arc radius of part far away more, so the cross section that intercepts on rotating shaft 34 directions (the Y direction of Fig. 2) ( cross section 55,56 that is surrounded by the hole wall cross section in as Fig. 6) has certain inclination with respect to the Y direction, go up arc radius with for example width (Y direction) and compare with the pure circular-arc coupling component of Y direction keeping parallelism, can increase the two-dimentional momentum in cross section on Y direction and the vertical with it directions X for certain, cross section.
As shown in fig. 1, be under the open mode at lid 39, open direction at downward direction and lid and be subjected to excessive heavy burden easily, but this moment coupling component 35,36 directions X and open on the direction with respect to below the intensity of bearing a heavy burden be directly proportional with the two-dimentional momentum in the cross section of Y direction.Therefore, even the width dimensions of coupling component 35,36, thickness etc. can not strengthen, also can improve its intensity by improving cross section two dimension momentum, can prevent that coupling component 35,36 from deforming when being subjected to too big heavy burden, thus the brisk sense of operation when keeping the switching of lid 39.
In addition, as shown in Figure 2, because two coupling component 35,36 has symmetry in the cross section ( cross section 55,56 that is surrounded by the hole wall cross section in as Fig. 6) that rotating shaft 34 directions (Y direction) intercept with respect to center line 52 inclination angles, when opening direction at lid 39 is to be subjected to excessive heavy burden on the directions X to do the time spent, though mounting portion 37,38 has the tendency that deforms towards center line 52 directions respectively, but since the mounting portion 37,38 coupled/be fixed on the lid 39, such distortion also just can be suppressed.Like this, by enlarging section two dimension momentum, can form the structure that the distortion on the cross-wise direction is cancelled out each other, the intensity of coupling component 35,36 also can improve.
In addition, as shown in fig. 1, by coupling component being divided into two coupling components 35,36, be used for mounting portion 37,38 connect/be fixed on screw 53,54 on the lid 39 the interval can strengthen.Though lid 39 thickness are very thick and have the transparent inner cap 51 that glass is made, weight is heavier, and the interval between the mounting portion 37,38 is big more, and the position of lid 39 is just stable more, thereby can prevent that lid 39 is because of deadweight occurrence positions skew downwards.
After having adopted above-mentioned structure, be under the closing state at lid 39, the situation that contacts of inner cap 51 and seal member 49 is relatively more even on whole circumference, thereby the opening portion 31 of washing machine body 32 is remained under the stable watertight state.
In addition, when lid 39 was in the heavy burden that adds downward (Y direction) under the open mode, if coupling component is not cut apart (promptly only being one), then whole coupling component can deform on wrap direction.In order to prevent distortion, the measure that need take to increase thickness, increases raising intensity such as width.By being divided into two coupling components 35,36, will have tensile force to have an effect on the coupling component 35, on the coupling component 36 then compressive have an effect, the distortion on the bending direction can reduce.In addition, by being divided into 2 coupling components, the stressed position on the rotating shaft support unit has also become 2 places, and the stress of generation also can be suppressed to original half.Like this, even if do not increase by two coupling components 35,36 thickness and width dimensions separately, also can improve the intensity of coupling component.
In addition, on above-mentioned circumferential butt 46, be provided with for two slits 47,48 that coupling component 35,36 passes.If coupling component is not cut apart is width widen, and such slit is with elongated, and the intensity of cover plate 46 will descend.Therefore, by coupling component is cut apart, slit also can be cut apart, thereby can guarantee the intensity of cover plate 46.
In addition, coupling component 35,36 with the rotating shaft 34 of these two coupling components and roughly be on the plane of the center of circle 57 decisions of lid 39 of circular shape cross section 55,56 (be the hole wall cross section on every side) as shown in Figure 6, with respect to the roughly rectangular extended line 58,59 of their length direction respectively towards near the extensions center of circle 57 of lid 39.
In general, also can see clothing in the swing roller 1 in order to make the user under lid 39 closed conditions, lid 39 is provided with the transparent inner cap 51 that materials such as glass are made.But, exist transparent part in design with respect to the lid 39 that roughly is circular shape to do may be big requirement, and in use also have the opening portion 31 of washing machine body 32 will make more greatly with the requirement of taking-up/input of making things convenient for clothing.
Therefore, circumferential butt 46 will be done narrowlyer in radial width, but also needs to guarantee to be provided with slit 47, the 48 necessary width that pass for coupling component 35,36.For example coupling component 35,36 is under the arc radius on the width (Y direction) keeps certain, the occasion of cross section for the pure circular arc parallel with the Y direction, when increasing the thickness of coupling component in order to improve intensity, the radial width of cover plate 46 also will increase, and so the transparent part on the lid 39 also will correspondingly reduce.
But, make the extended line 58,59 roughly rectangular point near the center of circle 57 of lids 39 shape by employing with respect to the length direction in the cross section 55,56 of coupling component 35,36, even if widened the words of the width of coupling component 35,36 in order to improve intensity, also radial extent that will cover plate 46 do the very wide slit 47,48 that just can form, so just can satisfy the requirement of above-mentioned design aspect and ease of use aspect simultaneously.
As mentioned above, adopted the opening portion 31 in washing machine body 32 the place aheads to be covered in the mode that opens and closes freely in the present embodiment by lid 39, washing machine body 32 is provided with the rotating shaft 34 of lid 39, and rotating shaft 34 and lid 39 are by two coupling components 35,36 structures that link, two coupling components 35,36 roughly to be with rotating shaft 34 be the circular shape at center, and two coupling components 35,36 each other the arc radius from position that must be far away more also just become big more, therefore, coupling component 35,36 intensity can improve, and lid 39 is subjected to excessive heavy burden appearance under open mode distortion just can prevent; Simultaneously, lid 39 is not prone to position skew, thus the watertight state can stably keep closing the time.
In addition, because the arc radius that two coupling components 35,36 leave position far away more each other also just becomes big more, so the processing easily that will become of the parts of coupling component 35,36, manufacturing cost also can reduce.
In addition, because lid 39 roughly is circular shape, and by two coupling components 35, cross section 55 on the plane of 36 rotating shaft 34 and 57 decisions of the center of circle that roughly is circular shape of lid 39, in 56, with respect to the roughly rectangular extended line 58 of its length direction, 59 point near the center of lid 39, therefore, two coupling components 35, even 36 distance widens, the mounting portion 37 of lid 39,38 required radial width can not change yet, thereby needn't strengthen lid 39 and just can strengthen distance between the securing member, the watertight state of being realized by seal member 49 when lid 39 is closed also can keep stable.
In addition, in the present embodiment, though show resemble shown in Fig. 1 or Fig. 2 the arc radius of two coupling components 35,36 be changed to the arc radius R2 of the arc sections of leaving each other farthest 42,43, the example that radius strengthens gradually from the arc radius R1 of the immediate each other arc sections 40,41 of the width of coupling component 35,36, but, can not reach same effect even do not add long radius yet.Certainly, under the occasion that radius increases, has the advantage that component processing is carried out easily, manufacturing cost can descend of coupling component.
In sum, tumbling-box washing machine described in the present invention is by improving the intensity that lid is attached to the coupling component on the washing machine body, can prevent to deform when lid is subjected to excessive heavy burden under open mode, simultaneously, lid is difficult for the occurrence positions skew, can make the watertight state when closing keep stable, therefore, be highly suitable for devices such as tumbling-box washing machine operations such as clothing wash.
