Abstract
The invention provides a washing machine cover structure which can eliminate the impact sound during opening and closing the washing machine cover and smoothly operate the opening and closing, comprising a cover freely opened and closed on the washing machine top cover; an elbow joint spring whose applying force to the opening and closing direction of the cover can be switched and a rotary buffer damper for attenuating the cover rotation. The buffer damper is equipped in the buffer damper in a freely rotation and sliding way. The damper is kept in a free rotation range provided with a preset angle in the rotation direction between the damper retainer and the buffer damper. At the initial stage of opening and closing of the cover, the attenuation of the buffer damper does not act on the cover rotation owing to the free rotation range. Thus, the user can open and close only with a force against the load such as the elbow joint spring and the cover dead weight in the initial stage. The opening and closing operation is convenient.
Description
Technical field
The present invention relates to a kind of open-close structure that can make the washing machine hood that opening and closing operations carries out easily.
Background technology
In existing washing machine hood structure,, generally all be provided with damping mechanism (example wherein can be opened 2000-167290 with reference to the Japanese patent gazette spy) in order to prevent very big strike note to take place when the cover opening and closing.
The cover structure of the existing washing machine in the above-mentioned document 1 has been shown among Figure 12, and Figure 13 is the partial side view of this washing machine after the part excision, and Figure 14 is the side view of cover part after local excision of this washing machine.
As shown in Figure 12, steel ladle 2 is bearing in the inside of the outer container 1 of washing machine body with the vibrationproof hang by elastic bearing mechanism 3, the inside of steel ladle 2 is provided with the double steel ladle 4 that takes off of laundry that can do washing with rotary dehydration, and the double bottom of taking off steel ladle 4 of this laundry is provided with the rotation agitator 5 that is used to stir clothing freely.The agitator 5 and the double steel ladle 4 that takes off of doing washing are rotated driving by the motor on the outer bottom that is fixedly mounted on steel ladle 27.
In addition, the top of outer container 1 is equipped with top cover 15, and the centre of top cover 15 is provided with the washings gateway 16 that communicates with the double inside of taking off steel ladle 4 of doing washing, and there is switching plane cover 17 freely the top of this washings gateway 16 by pivotal mounting.Cover 17 carries out the protecgulum 19 of opening and closing operations by the user to it and the bonnet that is in the rear 18 that connects with protecgulum 19 in rotary mode constitutes.In Figure 12, cover 17a shows the state when opening, and protecgulum 19a and bonnet 18a are folded into parastate.In addition, shown in cover 17a, when opening cover 17a turn to body surface position slightly in vertical state on.
During laundry, the user lifts from the K in the cover 17 the place aheads protecgulum 19 of naming a person for a particular job earlier, makes it to open towards the rear, clothing is fed into by washings gateway 16 from the top that laundry is double takes off the steel ladle 4 or therefrom take out again.The agitator 5 and the double steel ladle 4 that takes off of doing washing roughly rotate under level under the motor 7 of the outer bottom that is fixed on steel ladle 2 drives, and play the effect of washing or dehydration.The washing machine of this structure is generally known as " vertical " washing machine.
As among Figure 13 through shown in the side view of local excision, the left and right sides face of the rearward end of bonnet 18 is provided with horizontal axis hole 20, and top cover 15 is provided with the axle support 22 of protrusion, and axle support 22 is provided with horizontal protrusion, can be inserted into the axle 21 in the axis hole 20.Axle 21 is embedded in the axis hole 20 on the bonnet 18 with the form that has certain interval, by rotating shaft cover 17 is supported with the form of rotating freely.The back lower place of the axis hole 20 on the bonnet 18 is provided with the lever body 24 integrally formed with bonnet 18, and lever body 24 is provided with sector gear 29, and sector gear 29 is formed on the lower end of lever body 24.In addition, the rear portion of top cover 15 is provided with the tooth bar 25 that can move forward and backward in the inside of top cover 15, and the horizontal teeth 31 on above-mentioned sector gear 29 and the tooth bar 25 Nogami are mutually closed.Tooth bar 25 is by connecting rod 26 and be arranged on the back lower place of top cover 15, provide the damping unit 27 of resistance to link on horizontal axis.
In addition, for to cover 17 towards opening or closing direction applies assistance force, toggle spring 30 also is installed on the lever body 24, the both arms of its torsion spring part extend to the outside.During for level, it is the active force of the counter clockwise direction (arrow F) at center that toggle spring 30 is applied with axis hole 20 for lever body 24 at cover shown in Figure 13, thereby desire is closed cover 17.
Like this, when the arrow A direction was opened, lever body 24 was that rotate towards the B direction at the center with axle 21 with cover 17, with sector gear 29 Xiang the tooth bar 25 that closes of Nogami move towards the C direction, this moment, damping unit 27 did not produce resistance.On the other hand, when open mode was closed (E direction), the tooth bar 25 that closes with sector gear 29 Nogami (G direction) towards the rear moved, and can be subjected to the resistance of damping unit 27, thereby slow down the velocity of rotation of cover 17 with cover 17.
That is, when opening cover 17, can open with not being subjected to resistance, the elastic force that when closing cover 17 toggle spring 30 is applied towards closing direction obtains relaxing, thereby close Shi Buhui at cover 17 fierce strike note takes place.
In addition, as shown in Figure 14, but in the cover 17 that is the bending structure, also be provided with devices such as damping mechanism 39 in the connection part between protecgulum 19 and the bonnet 18.Like this, when when opening or close top cover 15 being carried out bending with respect to cover 17, just rapid rotating operation can not take place.
But, when adopting above-mentioned existing mechanism, though can eliminate fierce strike note when cover 17 is closed during from open mode, but when closed condition is opened, bonnet 18 is opened to respect near the vertical position of top cover 15 and when stopping, damping unit 27 does not produce resistance, and fierce strike note still can take place between the stop component of bonnet 18 and top cover 15.
In addition, in above-mentioned existing formation, desire with cover 17 when closed condition is opened, except the resistance of spring etc., also can produce resistance when gear part 29 and tooth bar 25 De Nogami contracts, so can feel to operate when the user opens cover very heavy to rotating.
In addition, in existing formation because tooth bar 25 and damping unit 27 be arranged in the top cover 15, with the integrally formed sector gear 29 of cover 17 again with tooth bar 25 on horizontal teeth 31 advance capable Nogami and close, so it is very high that parts precision and assembly precision require, and exists problems such as production efficiency is not high.
In addition, though the structure that cover 17 is divided into protecgulum 19 and bonnet 18 has been shown in the top existing washing machine example,, in general, cover is not cut apart but to be the example of a block structure also a lot.In this case, because the influence of the damping unit 27 the operation of closing from open mode, with cover 17 when closed condition is opened, the opening auxiliary force and all will have an effect of the inertia force of whole cover and toggle spring 30, so cover can be opened apace, produce stronger strike note, can feel very awkward when the user uses.
In addition, in recent years along with the variation of washing machine appearance design, the employing that has in the shape of cover have a structure of curved surface, and in order to guarantee the intensity when push the top, adopted under a lot of situations and had the spherical surface construction of projection upward, and, need to improve the thickness of cover for proof strength, form thicker structure.Under these circumstances, adopt protecgulum 19 to add 2 formations of bonnet 18 again, protecgulum 19 and bonnet 18 folded when cover 17 was opened, and it is very big that thickness will become, and a part is blocked in washings gateway 16, and ease of use can be subjected to appreciable impact.
Therefore, for having curved surface, having for the taller cover of complicated appearance design and intensity, just need constitute by the cover of the monoblock structure that does not carry out bending, and be also to be easy to structure by the switching of operating strike note, reaching lid that can prevent that simple assembling procedure just can be realized, even have the cover of constant weight, also require when opening and closing, not produce bump.
Summary of the invention

The specific embodiment
Come with reference to the accompanying drawings one embodiment of the present of invention are elaborated.It is pointed out that simultaneously such embodiment does not have the effect that limits the scope of the invention.
(embodiment)
Fig. 1 is the outside drawing of the washing machine in one embodiment of the present of invention 1, partial cutaway side view when Fig. 2 carries out opening and closing operations for the cover of representing this washing machine, Fig. 3 is the partial section of cover section construction of this washing machine of expression, and Fig. 4 is the sectional view of the formation of the cover of this washing machine of expression and cover spring section.
Shown in the outside drawing among Fig. 1, the top of washing machine body 51 is provided with top cover 52, the position that the upper surface of described top cover 52 roughly is in central authorities is provided with switching cover 53 freely, and the place ahead of top cover 52 is provided with the control panel 55 that the operation of washing machine is controlled.
As represent opening and closing operations shown in Figure 2 of cover, cover 53 is a center of rotation with axis hole 57, the basic LH position that can always be opened to from the position of closed condition L0 near vertical angle, and the toggle spring 66 that the back will be mentioned has for cover 53 towards the formation of opening or apply towards closing direction with switching elastic force.
When the user opens the operation of cover 53, at first cover 53 is raised to the L1 position with certain altitude from closed condition L0, then by intermediate point L2; After this intermediate point L2, the force direction that adds of toggle spring 66 switches.Turn to after the L3 position, even staff unclamps, cover 53 also can automatically be opened to fully open position LH under the elastic force effect that toggle spring 66 applies.
Conversely, when the open mode of LH is closed, as long as make cover 53 be closed to the L2 position again by the L3 position, the adding force direction and will switch of toggle spring 66.When being closed to the L1 position, cover 53 will be closed to the L0 position naturally under deadweight and the elastic force effect that applies of toggle spring 66 described later.
In addition, in the above-mentioned process of opening cover 53, from the closed condition of L0 between the L3 position, the toggle spring force that need head on the deadweight of cover 53 and apply towards closing direction is with cover 53 pull-ups, crossed after the L3 position, rotating operation will be relaxed by damping mechanism described later, is not opening only fully open position LH under the situation to the fierce impact of the structure generation of cover 53 rest position.
On the contrary, when closing cover 53, arrive the process of intermediate point L2 position through L3 beginning, need head on the strength that cover 53 is carried out afterburning toggle spring towards closed condition by staff cover 53 is rotated from open position LH.Close after the L1 position, cover 53 will rely on deadweight and spring described later structure to close naturally, and meanwhile damping mechanism carries out the rotating operation when closing lentamente, and cover 53 will not take place to be closed to the L0 position under the fierce situation of clashing into top cover 52.
The structure of cover 53 as shown in Figure 3, roughly rounded and cross section is lid upper ledge 60 that the cover body 58 of protruding dome shape, lid lower frame 59 that plan view shape roughly is the bagel shape and plan view shape roughly be horseshoe-shape and overlaps and form by plan view shape, lid lower frame 59 from the below edge portion to cover body 58 support, lid upper ledge 60 covers from the edge portion of upper surface with cover body 58.Cover body 58 can be formed by (for example) transparent resin material etc., can the user state etc. by visual washing clothes to washing machine inside confirm.
The rear portion of cover body 58 is provided with any the low platform portion 61 of subsiding, and install the tabular cover plate of making by non-transparent material 62 from the top, constitute the connection component parts of horseshoe-shaped lid upper ledge 60, form simultaneously and a kind ofly can not see its in-built appearance design described later from the cover body 58 of transparent resin parts.
The rear of lid lower frame 59 is provided with the convex shape hinge 63 that forms one with it, and is provided with axis hole 57, and and the movable end 65 that catches on of the movable side arm 67 of toggle spring 66 etc. at the rotating operation center when becoming cover 53 and opening and closing.
Described toggle spring 66 is the torsion spring type ring spring, extend to the outside at its two ends, constitute movable side arm 67 and fixation side wrist 64, the stiff end 99 of fixation side wrist 64 is supported on the top cover 52, and the movable end 65 of movable side arm 67 connects mutually with the front position of rotating the hinge 63 on mode and the cover 53 freely.
For being connected and fixed the imaginary line W at center that the end 99 and the pivot of cover 53 are axis hole 57, if movable end 65 is arranged in (Fig. 3's) right side, then toggle spring 66 applies elastic force for movable end 65 towards the direction shown in the arrow S of Fig. 3; If movable end 65 is positioned at the left side of imaginary line W, then toggle spring 66 applies elastic force with respect to movable end 65 towards the direction shown in the arrow P of Fig. 3.
Like this, when cover 53 is in closed condition (the L0 position among Fig. 2), movable side arm 67 for cover 53 with axis hole 57 be the center rotate counterclockwise fasten the direction reinforcing; And when opening (being summary shown in dotted lines in Figure 3 LH position in vertical state) at cover 53, hinge 63 forwards below (being the H position that dotted line is represented among Fig. 3) to, and movable side arm 67 is the direction reinforcing that the center clockwise rotates for cover 53 with axis hole 57.
The formation of cover spring section has been shown among Fig. 4 (a), Fig. 4 (b).As shown in Fig. 4 (a), Fig. 4 (b), in the inside of installing the spatial portions 100 that the rear of lid lower frame 59 back at cover body 58 form, be provided with that an end of the spring shaft 80 of cover spring 69, supporting cover spring 69 and cover spring 69 constitutes materials such as its metal foils of exerting pressure, be fixed on the parts such as lid stiffener 79 on the lid lower frame 59.
The other end 101 directed downwards of cover spring 69 are inserted/are fixed on the top cover stiffener 76 that is installed on the top cover 52 from the top.
In Fig. 4 (a) that cover 53 is closed, cover spring 69 is bent to and roughly is 90 degree, along the pivot of the spring shaft 80 lid hinge axis 77 of the pivot of cover 53 (perhaps with) cover 53 is applied elastic force clockwise, that it is opened by lid stiffener 79.At this moment, toggle spring 66 is applying power anticlockwise, that it is closed by 63 pairs of covers 53 of hinge, but because the power that lid is opened that cover spring 69 produces is set to the sum that increases the weight of less than the weight generation of making of producing of toggle spring 66 elastic force that lid closes and cover 53 itself, thus cover 53 the maintenance closed condition.
Be raised to the approximate vertical position at cover 53, when as shown in Fig. 4 (b), being in open mode, 66 pairs of covers of toggle spring 53 produce and make it be opened to the elastic force of approximate vertical position, 53 of covers remain under the open mode by this strength, and cover spring 69 is the state that is extended into the free shape of approximate vertical (linearly) at this moment, can not produce the elastic force that it is opened by 79 pairs of covers of lid stiffener 53.
Also illustrate among Fig. 3, the cover 53 cover bodies 58 that adopt transparent resin materials to make mostly combine with lid lower frame 59 and lid upper ledge 60 in recent years, and it is firm and have a structure of constant weight to become comparison.The elastic force that working load when opening cover 53 in order to reduce, cover 53 are in closed condition lid spring on opportunity 69 is set the most by force.For so more intense elastic force is supported, lid stiffener 79 is waited by the bullion steel plate and constitutes, the spring pressure that one end of cover spring 69 is produced can directly not be added on the lid lower frame 59, simultaneously the rear portion of lid lower frame 59 is strengthened, and enables to bear to cover opening and closing operations.
In addition, as mentioned above, the effect of cover spring 69 is to reduce the user with the operation power of cover 53 when the closed condition shown in Fig. 4 (a) is opened, and is under the open mode at the cover 53 shown in Fig. 4 (b), becomes the free state that does not produce elastic force.Therefore, when being assembled into cover spring 69 on the top cover 52, can under spring does not produce the free state of elastic force, not be inserted into the cover 53 of Fig. 4 (b), so just can save special erecting tools from vertical direction.

The fore-end of damping axle 85 is provided with planar portions 95, and this planar portions 95 is inserted into the damping support of chucking top cover 52 (not shown among Fig. 8) and constructs 73 parts omitted and be in the support 74 of Y word shape the state that cannot not become rotatablely.Simultaneously, be fixed on installation hinge 88 on the cover 53 (not shown among Fig. 8) when rotating along with the opening and closing operations winding Buddhist nun axle 85 of cover 53, keep the opening portion 87 of body 81 and the end face of the convex shaped part 86 on the damper housing 84 on direction of rotation, to withstand in the later anglec of rotation at damper, rotary manipulation will be subjected to resistance, obtain buffering.
In other words, in the side view of Fig. 8 (a), push up in free rotational angle (being angle T among the figure) scope before the end face of opening portion 87 side of convex shaped part 86 when hinge 88 being installed rotating, hinge 88 is installed will rotate with not being subjected to resistance, and withstand the cushioning effect of rotary manipulation afterwards, thereby make the opening and closing operations of cover 53 be subjected to attenuation with isolation damper 72.
That is to say, in the opening and closing operations of cover 53, be not that all rotations all are applied with attenuation, but be provided with certain free rotational angle, and just the angle to regulation is applied with attenuation.Like this, the part in the switching operation of cover 53 is carried out swimmingly, the impact in the time of can preventing to open and close simultaneously.
In addition, the formation of free rotational angle neither be made of separately 84 1 parts of damper housing, but keeps opening portion 87 on the body 81 and the convex shaped part 86 on the damper housing 84 to constitute together by being formed on damper.Why like this, to be because the setting of the free rotational angle in cover when operation only just can be finished easily and simply by the shape of opening portion 87.
In addition, the damping axle 85 of isolation damper 72 is installed to the damping support structure 73 of roof side in non-rotatable mode, can make the below shown in the arrow Y of planar portions 95 from Fig. 8 (c) of leading section of damping axle 85 slip into, be clamped in the support 74 that slightly is the Y font.Like this, also described by Fig. 5 above, and only needed cover 53 is installed to top cover 52 from the top, and just can finish assembling operation, production efficiency can be improved.
As shown in Figure 9 along shown in the sectional view of the rotating shaft of cover 53, the inside of the spatial portion 100 that forms in cover body 58 and lid lower frame 59 assembling backs, roughly be on the center (shown in the R-R line) of cover body 58 and cover plate 62, be provided with and be inserted into columnar damper in freely mode of rotation and keep isolation damper 72 in the body 81, and cover spring 69 and the spring shaft (80) that is on the same axis (shown in J-J) is set respectively in the left and right sides of isolation damper 72.
The outside about cover spring 69, be provided with to be used for cover 53 supported and make it the lid hinge axis 77 that relative top cover 52 can open and close, lid hinge axis 77 is on the identical axis with spools 80, inserts and remains in the axis hole 57 and top cover side shaft support holes 71 on the framework hinge 63 of lid lower frame 59.
In addition, cover spring 69, supports it on spring shaft 80 in the center of ring spring.Spring shaft 80 is supported in the aperture 103 on a plurality of lugs 102 on the lid stiffener 79 that metal foil etc. constitutes.
R-R (Fig. 9) the direction cross section of passing isolation damper 72 has been shown among Figure 10.The mounting means of isolation damper 72 is, keeps body 81 to form one with damper and the installation hinge 88 that therefrom extends out is formed in a plurality of projections 105 of one with lid lower frame 59 and screw tap screw 104 is clamped and fixing.
In addition, the axis of the spring shaft 80 of the lid hinge axis 77 of cover 53, the damping axle 85 of isolation damper 72, cover spring 69 is set on the same straight line (the J-J line among Fig. 9), and cover 53 also carries out around identical axle around the operation of the switching of lid hinge axis 77, the rotating operation of isolation damper 72 and the rotating operation of cover spring 69.Like this, operation can become simply, except the load on spring with cover spring 69 is applied to the mechanism on the cover 53 and the rotating operation of cover 53 is transmitted the rotary transfer machine of damping force, need not to be provided with other specialized agency.
The operational circumstances of the opening and closing operations of the cover 53 that has illustrated among Figure 11 and buffering damper 72 is under 1. cover 53 closing state shown in (L0 among Fig. 2), and convex shaped part 86 is in the state that does not have resistance on the direction of rotation in damper keeps the opening portion 87 of body 81.At this moment, even cover 53 rotates towards the direction shown in the arrow Q, be in the free slewing area of T in the angle that apical grafting does not take place with non-opening portion 96, the attenuation of isolation damper 72 can be to the rotation generation effect of cover 53 yet.
Next, cover 53 is further opened, because convex shaped part 86 does not still withstand with non-opening portion 96, so isolation damper 72 still do not produce attenuation, cover 53 can not be subjected to that resistance ground is smooth and easy to be opened under state 2..
When cover 53 was opened to 3. position, even staff is no longer opened the operation of cover 53, toggle spring 66 can switch to cover 53 towards opening the direction reinforcing, and cover 53 can automatically continue to open.And, because non-opening portion 96 withstands with convex shaped part 86 at the contact site 97 of 2 positions up and down, isolation damper 72 will begin to produce attenuation, in the process of the approximate vertical position in 4. cover 53 is got to always (LH among Fig. 2) impact of opening is relaxed, continue to produce attenuation.
When promptly 4. state is closed from open mode with cover 53, non-opening portion 96 becomes with convex shaped part 86 from contact site 97 original and that convex shaped part 86 withstands and separates, attenuation no longer takes place, even the strength of opening the power that direction applies by people's manual task with the court that surpasses toggle spring 66 and 69 pairs of covers of above-described cover spring and apply is pressed (closing) to 5. state with cover 53, because apical grafting takes place with non-opening portion 96 in convex shaped part 86, isolation damper 72 can not produce attenuation, and cover 53 can not have that resistance ground is smooth and easy to be shut.Switch to cover 53 towards making after its direction of closing carries out afterburning 6. state at toggle spring 66, convex shaped part 86 and non-opening portion 96 withstand mutually at the contact point 98 of a side opposite when opening, attenuation begins to work, after this attenuation continues to have an effect, and the impact when making cover 53 arrival positions 1. be the approximate horizontal state will obtain relaxing.
Operational circumstances, effect and effect to washing machine hood with above formation is described below.
At first, the rotary isolation damper 72 of the rotation of cover 53 is accommodated damper maintenance body 81 in rotations/slip mode freely owing to be used for decaying, and, damper keeps body 81 and buffering damper 72 to be provided with the free rotational angle of regulation on direction of rotation, therefore, the damping force of isolation damper 72 did not exert an influence to the rotation of cover 53 in the initial period of opening cover 53, this external closure plane covered 53 o'clock, because the existence of free rotational angle, the damping force of isolation damper 72 can not exert an influence to the rotation of cover 53 in the initial period of shutoff operation yet.
Therefore, in the initial period of opening the cover 53 that is in closed condition, because the damping force of isolation damper 72 is inoperative, the operation of the end of pull-up cover 53 can be carried out like a cork; In the initial period of closing cover 53, because the damping force of isolation damper 72 is also inoperative, the user also can operate like a cork in addition.
In addition, because damper keeps body 81 and isolation damper 72 to be configured to like this, promptly, in the process of opening or closing cover 53, the damping force of isolation damper 72 the spring force of toggle spring 66 reinforcing of cover 53 is being opened or closing direction on just have an effect after switching, therefore, as long as the user feels that in the opening and closing operations of cover 53 load that is subjected on hand unclamps hand when changing, open and shutoff operation all can automatically be finished, and isolation damper 72 can also produce attenuation simultaneously.
In addition, owing to keep in the opening portion 87 on the body 81 by being embedded in damper with integrally formed convex shaped part 86 trips of damper housing 84, the setting of free rotational angle free rotational angle is set, so only just can be finished easily and simply by the shape of opening portion 87 on direction of rotation.
In sum, the above embodiment of the present invention can not produce undesirable strike note when opening and closing, and do not produce attenuation at the initial period isolation damper that opens and closes operation, operation becomes very light, and the words of midway loosing one's grip in opening and closing operations also can automatically be finished switching, the bump when opening and closing can be eliminated simultaneously, thereby a kind of washing machine hood that two kinds of operations of switching can be carried out easily, opening and closing operations can be finished swimmingly structure of cover can be realized.
