Below, use accompanying drawing that one embodiment of the present of invention are described.
Fig. 1 is a stereogram of showing the washing machine outward appearance of present embodiment, and framework possesses: the housing 1a of main composition framework sidepiece, main composition framework top also cover the upper opening of housing 1 and the top cover 1b (hereinafter referred to as loam cake) that installs and the lower cover 1c of main composition framework bottom.
On Qianmen 2, disposed guidance panel 100, possessed washing thereon, dewater, the operating mechanisms such as switch 6 of action indication such as drying and with the indication mechanism 7 to user's display action state or remaining time etc. such as liquid crystal or light emitting diode.Possesses the handle 5 that is used for shaking hands when opening Door by Hand at Qianmen 2 by near the central authorities back door 3.
Front part (user's side) at loam cake 1b possesses the power switch 12 of the ON/OFF that carries out power supply and the door on-off switch 13 of the switching of indication door.In addition, be provided with the scupper hose 80 that is used for draining in the washing machine side.
In addition, as Fig. 2 and shown in Figure 3, be provided with the washing dehydration mechanism 10 that constitutes by a plurality of grooves in the inboard of housing 1a.Go out though this washing dehydration mechanism 10 is not shown, it has as the water jacket of water receiving tank and puts into sink (being also referred to as washing and dewatering groove or the inside groove) 10a of washings in the inboard of water jacket, in the internal configurations of sink as the rotor that washings is applied the transmission device of mechanical force.
In addition, the outer capping 10b that covers sink 10a has been installed on water jacket top.On outer capping 10b, be formed with the washings input port that is used to put into or take out washings, be provided with the inside door 10c that can cover this input port with opening and closing.Present embodiment concerning the washing machine that does not have functions/drying, is not provided with inside door 10c owing to being that example has inside door 10c with the scrubbing-and-drying unit with functions/drying usually.In addition, what show in Fig. 3 is the state of opening inside door 10c, takes off the state (dotted line) of inside door 10c again.
At loam cake 1b, at the rear portion of the rear side that is equivalent to the washings input port, the pump of the water supply electromagnetic valve that the oriented sink 10a of folding and unfolding supplies water, extraction water for bathing etc., but do not illustrate.
As Fig. 2 and shown in Figure 3, on loam cake 1b, be formed with switch door 2,3 is embedded in wherein recess 20.Like this, the height of the part of the top and switch door 2,3 that surrounds the loam cake 1b that switch door 2,3 is installed of switch door 2,3 is roughly the same.In addition, be formed with the washings input port at recess 20.Be provided with the guide rail 21 as guiding mechanism of flute profile at the inner side surface of holding up from this recess.
The part of the intermediate support 4 at Qianmen 2 and back door 3 is cylindric, and portion possesses secondary spring described later and friction mechanism within it, makes the structure of angle for opening and closing around the central shaft of cylinder between Qianmen 2 and the back door 3.Attached spring or the friction mechanism formation of helping opens or closes 2,3 o'clock auxiliary force of switch door generation mechanism.
As shown in Figure 4, back door 3 is being supported the activity supporting point 9 that rotates by axle and freely is being rotated, and possesses rotary type guide roller 8 near the front end at Qianmen 2, and it aims at also supported movably along being located at guide rail 21 on the medial surface of holding up from recess 20 sliding freely.
Owing to adopt said structure, so from door closing state shown in Figure 1, in case hand is stretched into handle 5 up to be lifted, just as shown in Figure 2, door bends to arch at intermediate support 4 makes this intermediate support 4 lift and open, by further then opening, as shown in Figure 3, Qianmen 2 and back door 3 become mutual surface position relation toward the outer side, and become the state of standard-sized sheet.
In addition, in Fig. 2, the 37th, secondary spring described later, the 22nd, become the sub-arm that opens and closes the part of auxiliary body described later, the 23rd, a front end part, that make above-mentioned sub-arm that is formed at 21 on guide rail is outstanding on guide pass, is used for the slit that moves along the curved face part of guide rail.
Secondly, with Fig. 4 and Fig. 5 the front end curve form of guide rail 21 is described.
Fig. 4 and Fig. 5 are used for the profile that the shape to guide rail 21 describes.In Fig. 4, guide rail 21 is the linearity for tilting above the profile of washing machine is configured to, and the front is from the continuous circular shape of above-mentioned straight line.The shape that the position straight line of the guide roller 8 when on the other hand, the guide rail among Fig. 5 21 is made with switch door standard-sized sheet during with full cut-off is connected.
In Fig. 4, are the structures that can move along guide rail 21 owing to be located near the summary front end at Qianmen 2 guide roller 8, so the track that Qianmen leading section 2A passes through between the switching of door is the track 26A shown in the single-point dotted line.To this, above the sink 10 of washing machine, because can be, so to the less wastage in space as the installation region of built-in machine class 27 in the zone of not interfering with track 26.In the structure of present embodiment, because the front end R that is made up of planar section and round barrel shape curved surface of Qianmen 2 partly constitutes, so the thickness at Qianmen 2 can be thick goes out the front end R thickness partly that the round barrel shape curved surface is formed with being made of flat board to compare.In addition, when opening, because Qianmen front end 2A has to rise along curved surface R cylindraceous portion during beginning, so that the power of opening becomes is big.In addition, when closing to the doorstep, the position at Qianmen 2 descends hastily after the curved surface R cylindraceous portion because guide roller 8 moves to from line part, so be accelerated, the result when door is closed fully, impacts fiercely and closes, and produces impulsive sound.Produce and impact, the guidance panel 100 that is located on the Qianmen 2 will be subjected to its impact.Guidance panel 100 has display elements such as liquid crystal and light emitting diode and is used to drive the electronic circuit of display element, and applying impact is bad from the viewpoint of reliability.
On the other hand, as shown in Figure 5, make the linearly occasion of guide rail 21, the track that Qianmen leading section 2A passes through is 26B.Because track 26B is for to compare lower position with 26A, the installing space of the machine class 27 of interior dress diminishes, thereby unfavorable.Therefore, as shown in Figure 4, wish that guide rail 21 is provided with in the mode along the device profile.
Also have, in the present embodiment, described is that to make the curve form of device front be cylindrical shape, but is not limited to drum, also can be for example a plurality of continuous cylindric curved surfaces.
In the present embodiment, on middle hinge or root hinge, be provided with support spring.Below, with Fig. 6 to Figure 10 the support spring of hinge portion is described.
As previously mentioned, owing on Qianmen 2, possess guidance panel 100, because of the weight of door becomes big, thus from the state of door full cut-off shown in Figure 6, hand is led on handle 5, upwards pull the door open required power Fo and the mode that does not possess guidance panel 100 washing machine compare bigger.
Curve map with Figure 10 describes this tensile force.
The transverse axis of Figure 10 is the open angle at back door among the Fig. 7 that represents with Φ, and the longitudinal axis is the tensile force Fo at handle portion 5.Begin to open door in case apply tensile force, Qianmen 2 and back door 3 just bend to ' ㄑ ' word shape, become the mode shown in the dotted line 2 ' 3 ' 4 ' of Fig. 6.Guide roller 8 is pulled to the direction of back door fulcrum 9, presses on the guide rail 21 and along guide rail 21 and moves.Therefore, even in hinge portion support spring is set, the front end 2A of protecgulum 2 can getaway 21 yet and is jumped up.Because guide roller 8 moves along the front end R portion of loam cake, so the position of centre of gravity of door rises sharp, and owing to possess guidance panel 100 on Qianmen 2, thereby the tensile force of door becomes greatly sharp, gets maximum Max.Because guide roller 8 moves to along the line part of top summary planar portions from the front end R portion of loam cake, so by behind the A point of Figure 10, tensile force reduces gradually, the center of gravity CG of front and back door is cross over the rear from the place ahead of the hinge 9 at back door, is that zero position becomes 0 at the rotation momentum that is produced on every side because of deadweight W 3 fulcrums at the back door.Then, door arrives the position C point of standard-sized sheet.The angle that this is opened and the relation table of power are shown curve F1.
In order to reduce the maximum Fmax of tensile force among this F1, in the present invention, a certain side of back door fulcrum 9 or intermediate support 4, perhaps two sides have torsionspring 37,47.
Any torsionspring 37,47 all produces maximum moment at door closure state shown in Figure 6, is the angle of bearing the free state of loading hardly in door full-gear shown in Figure 9.Adopt this mode, at the maximum spring momentum Tc of door closing state generation shown in Figure 6, because this direction is the power of the direction of door before and after opening, so can reduce the power Fo that the carrying handle hand 5 that makes progress is opened door.The degree of the reduction of tensile force is because the moment Tc that produces with torsionspring big or small corresponding, so be maximum in the position of contract fully, B is almost nil in the position.To this, the tensile force F that possesses the occasion of torsionspring only reduces by torsionspring 37,47 applied force square Tc, becomes shown in the F2 of Figure 10 such.Make the moment that torsionspring 37,47 applies further become big, tensile force F further reduces and to become F3 such, but owing to so approach zero at the tensile force Fmin of the state of door contract fully, thereby produce following phenomenon.When closing, door is not to close quickly, but slowly close from the position of standard-sized sheet with hand, such shown in the dotted line of Fig. 6, when behind a little bit poorer state, unclamping hand with regard to Close All, very little (for example during 100g～200g) at Fmin, by resistance that frictional force caused and the Fmin balance that each one at door produces, the result, just such shown in dotted line among Fig. 62 ' 3 ' 4 ', with the door state phase down action of perk a little, and can not close fully.In this occasion, it is excessive to be judged as torsionspring 37,47 applied force square T.For fear of this state, the tensile force Fmin that begins to open there is lower limit, for example, need be for about 500gf.Shown in the F2 of Figure 10 is this state.
That is, torsionspring applied force square there is the upper limit, applies this above moment, the situation of will generator gate not closing.Therefore, limited to the reduction effect of the tensile force of additional moment, the maximum of the tensile force of this moment is the F2max of Figure 10, can not be reduced to above this value.
When at closing time action is described, the state of opening fully from door with this state is to the occasion of closing, because of comprising the weight of the front and back door of guidance panel, pass through between Fig. 8, Fig. 7 at state from Fig. 9,2 guide rollers 8 that possessed are along the direction acceleration of guide rail 21 to arrow C L at the Qianmen.Therefore, because when door becomes the state of full cut-off shown in Figure 6, guide roller 8 also continues to advance to the direction of closing door, so when door becomes the state of contract fully, guide roller 8 or front and back door conflict with loam cake and produce impulsive sound, simultaneously, point the danger that is sandwiched between loam cake and the front and back door in addition.
Secondly, other mechanism (spring support of front end) that reduces this F2max is described.
As mentioned above, only the maximum F2max that 37,47 pairs of torsionsprings reduce the door tensile forces are set as can be known boundary is arranged at back door fulcrum 9 or intermediate support 4.According to Figure 10, finish up to front R portion from the C1 position of door full cut-off, promptly the tensile force of ordering up to A becomes big, and by operator's operation, door is heavy especially.
Below, with Fig. 6 to Fig. 9 the reduction mechanism of the tensile force Fo of guide roller 8 when the scope of front end R portion is described.In Fig. 6, sub-arm 22 is supported for around rotation center 24 and freely rotates, and the one end is projected into the gathering sill from guide pass 21 by the slit 23 that is formed at guide rail 21, and the front end of sub-arm 22 is from the downstream contact of guide roller 8.Sub-arm 22 is a rotary structure in the scope of the opening of slit 23, and slit 23 is located at the scope of the front end R shape of washing machine, the scope of R promptly shown in Figure 7.
At this, concerning the washing machine of present embodiment, its profile is a part cylindraceous, and, guide rail 21 is a circular arc for the shape along profile, therefore, adopts the words of sub-arm 22 24 modes of rotating around the rotation center, because it is the mode of the front end of sub-arm 22, thereby proper for moving along guide rail 21.At this, the position of the center of rotation 24 of sub-arm 22 is can be not in full accord with the center of rotation of the front end R portion of washing machine yet, and concerning the scope R that sub-arm rotates, the front end of sub-arm 22 gets final product with the words that guide roller 8 contacts.
The part of sub-arm 22 is the carbine 25 that frame is lived spring 27, and spring 27 struts between projection 26 that is fixed in loam cake and above-mentioned carbine 25, produces the rotating torque of activity supporting point 24 to the direction of arrow C W that rotate.
As shown in Figure 6, in the door closing state, the power that is applied to guide roller 8 from sub-arm 22 is for maximum, and as shown in Figure 7, guide rail 21 moves on to planar portions from front end R portion, and at the terminal location of slit 23, the power Fc1 that is applied to guide roller 8 from sub-arm 22 is for minimum.
In door closing state shown in Figure 6, because the hinge 9 at guide roller 8 and intermediate support 4 and back door roughly point-blank, so apply the occasion of power Fc1 at front end to guide roller 8, because the momentum that produces around the hinge 9 at intermediate support 4 or back door is little, even guide roller 8 is applied power Fc1, Qianmen 2 and back door 3 can perks as the dotted line 2 ', 3 ', 4 ' of Fig. 6 yet.
Adopt this structure, the scope in the door opening of Fig. 6 to Fig. 7 can apply power Fc1 to guide roller 8 in the tangential direction of guide rail 21 from the front end of sub-arm always.Because the direction of this power is implemented the direction of stop in the occasion of closing the door for the speed that reduces door by guide roller 8, thereby have that reduction speed at closing time reduces impact at closing time and the effect of gently closing the door.Have again, when opening the door, for the direction of the tensile force that reduces the operator upwards pull handle, so even have the effect that also can open the door trippingly in the big occasion of the quality of front and back door.
In the present embodiment, as spring 27 usefulness extension spring be example, but be not limited to extension spring, also can be the sort of as shown in figure 11 structure, that is, make torsionspring 30 be wrapped in sub-arm 22 rotating fulcrum 24 around, the one end is hung on the sub-arm 22, other end 30a is hung on the fixed part of top cover such as projection etc., by sub-arm 22 being applied the momentum of arrow C W direction, and guide roller 8 is applied power Fa from sub-arm 22 front ends.Perhaps, as shown in figure 12, make the end prolongation of torsionspring 31 and, make the front end of torsionspring 31 directly contact also passable with guide roller 8 by between the slit 23.Adopt the structure of Figure 12, also can access same effect, can make designs simplification even save sub-arm 22.
Secondly, with Figure 13 to Figure 14 mechanism's (lock of front end) of further reduction impact is at closing time described.Among Figure 13, piston 33 makes an end outstanding from sleeve 34, and above-mentioned piston 33 is can be from the structure of sleeve 34 straight lines turnover.At the inner sealing of sleeve 34 the high grease of silicone fluid of viscosity, when the direction of arrow 35 moves,, produce the viscosity impedance at piston 33 because of the viscosity of grease of silicone fluid.The piston 33 that moves to the direction of arrow 35 utilizes and returns springs 34 and return original position.The front-end configuration of piston 33 becomes to contact with sub-arm 22, and open gradually at Qianmen 2, when sub-arm 22 arrives the position of the 22b shown in the dotted line, utilize sub-arm 22, piston 33 moves to the direction of arrow 35, and Qianmen 2 is closed, arrive the 22c position up to sub-arm 22, piston 33 continues to move.Around here, the power 0 of the direction of the arrow 36 that sub-arm 22 owing to be subjected to from piston 33 is produced by the viscosity impedance reduces so close the speed at Qianmen 2, can reduce Qianmen 2 when closing fully impact and mildly close.
When the operator opened the door, sub-arm 22 left piston 33 owing to utilize torsionspring 30 to clockwise rotate as shown to contact with guide roller 8 always, revert to original position so piston 33 utilization returns springs 34, the impedance when becoming door then and being closed.In the present embodiment, being illustrated to have sealed grease of silicone fluid at sleeve 32, but being not limited to grease of silicone fluid, also can be greases such as wax, or the structure that air is come in and gone out in sleeve also can.
In Figure 14, be to replace the viscosity impedance that illustrate among Figure 13 and the structure that produces the impedance that rubs.The 38th, possess friction impedance body 39 in the inboard, the elastomer of mutual crimping friction impedance body 39, from the A of Figure 14 to shown in the view (a) to (b), sub-arm 22 enters two words between the elastomer along the direction of arrow 35, the reaction force F22 that sub-arm 22 produces because of the distortion of elastomer 38 is subjected to hindering the frictional force of the direction that sub-arm 22 moves from friction impedance body 39.Adopt the words of this structure, in Figure 14 (c), Qianmen 2 is closed gradually, when sub-arm 22 arrives the position of the 22b shown in the dotted line, because sub-arm 22 enters between two elastomers 38,, be subjected to the friction resistance of the direction of arrow 36 from friction impedance body 39 because of sub-arm 22 so Qianmen 2 is closed the position that arrives 22c up to sub-arm 22 as Figure 14 (b), so the speed that Qianmen 2 is closed descends, the impact when Qianmen 2 is closed fully reduces and can gently close.
On middle hinge 4, lock is set or attenuator also can.Below lock or attenuator are described.
As shown in Figure 9, state from the door standard-sized sheet, make the words of closing sharp along arrow C L direction, because the inclined-plane of side step-down in front of guide rail 21 forms, so door quickens gradually, when being closed to the state of Figure 11, guide roller 8 contacts with sub-arm 22 and sub-arm 22 is rotated always, by the power of spring 27 or torsionspring 30,31 generations is imposed on guide roller 8 and can make a deceleration.Such as described in example 4 above again, by only further slowing down, can gently close the door at the frictional force or the damping force that near the state of door contract fully sub-arm 22 are applied on the direction that makes a deceleration.Yet, cross greatly and give and above-mentioned frictional force or damping force, can produce following shortcoming.Promptly, described same with embodiment 2, at closing time, be not a gas close door, but close at leisure with hand from fully open position, shown in the dotted line of Fig. 6 like that, when handle release after closing state fully, because the tensile force Fmin balance of friction resistance or damping force and door full closing state, thus door phase down action with the state of perk slightly, and do not close fully.Because this phenomenon takes place, thus in Figure 13 to Figure 14, illustrate, to only when door is closed fully near the power that applies when rubbing resistance or damping force higher limit is arranged, can not apply power above this higher limit.
Secondly, to preventing to stop halfway at closing time like this, and door from full-gear one gas the structure that also can gently close when closing describe.Figure 15 is a stereogram of showing an example of the structure that is located at the intermediate support 4 between Qianmen 2 and the back door 3.In the present embodiment, intermediate support 3 is divided into 3 parts along length direction, and the 1st unit 4a and the 3rd unit 4c and back door 3 are wholely set, and the 2nd unit 4b and Qianmen 2 are wholely set.The 1st unit 4a and the 2nd unit 4b and the 3rd unit 4c rotate mutually and are supported on freely on the axle, become the rotating fulcrum at Qianmen 2 and back door 3.
Secondly, the embodiment with Figure 16,17 pairs of these impedance applying mechanisms 40 describes.In Figure 16, flange 44 by only freely rotate in a direction, in one-way clutch 45 supports main shaft 46 of the locking of not rotating in the other direction.
In Figure 16, impedance produce mechanism 41 possess with respect to rotor plate 48, main shaft 46 with the 2nd unit 4a unitary rotation make rotate be subjected to regulation, with respect to the friction plate 49a and the 49b that clamp rotor plate 48 from both sides, apply by the spring of giving as security 51 and the stator 52 of spring by 50 couples of friction plate 49b of pad.Adopt this structure, in case main shaft 46 rotates, friction plate 49 rotates with main shaft 46, because rotor plate 48 is because of above the crushing clamp from both sides spring 51 is pressed against friction plate 49, so because of friction plate 49 and rotor plate 48 rotate mutual friction the time mutually, the extruding that mutual coefficient of friction and spring 51 cause is proportional to be decided rotating torque and can produce between main shaft 46 and rotor plate 48.Here, since only between main shaft 46 and flange 44, possess fixed rotation direction sting and one-way clutch 45, so can be between flange 44 and rotor plate 48, in idle running when a direction is rotated, when counter-rotation, apply fixed rotating torque.
That shown in Figure 17 is other embodiment.Be with the structure dissimilarity of Figure 16, produce mechanism 41 as impedance, replace friction plate and rotor plate, inside at the sleeve 53 of the structure of not rotating with the 1st unit 4a possesses rotor 54, by on the space 55 of inside, being sealed into for example big grease of silicone fluid of viscosity, only produce the viscosity impedance, can be between flange 44 and sleeve 53, in idle running when direction is rotated, to counter-rotation the time, apply fixed rotating torque.
Owing between the 1st unit 4a and the 2nd unit 4b, possess the impedance applying mechanism 40 of said structure, so, in case making Qianmen 2 and back door 3 rotates around intermediate support 4, owing to possess one-way clutch 45, so can promptly open Qianmen 2 and back door 3 mutually along arrow C L2 direction, the occasion of only closing the door of washing machine applies rotating torque, in the direction of opposite arrow OP2, promptly close the occasion idle running that the door of washing machine is opened at Qianmen 2 and back door 3 mutually.
From the state of door standard-sized sheet shown in Figure 9 via the state of Fig. 8, Fig. 7 when state one air to close of full cut-off shown in Figure 6 closes, produce load moment owing to be located at the impedance applying mechanism 40 of intermediate support 4 always, so compare with the occasion that does not have impedance applying mechanism 40, at closing time a speed along guide rail 21 actions is reduced.Therefore, owing to can make at state shown in Figure 7, promptly being located at guide roller 8 on the Qianmen 2 guide roller 8 when touching sub-arm 22 reduces along the speed of the direction of arrow C L, thereby the action of door of state that arrives contract fully shown in Figure 6 up to door is because of almost with identical when making the static state relieving hand of door in the position of Fig. 7, so power Fc1 that utilizes sub-arm 22 to produce, door is after guide roller 8 is run into front end R portion, slow down impact when fully reducing door and closing fully, making quiet and gently closing the door becomes possibility.
At this moment, the load moment that applies by impedance applying mechanism 40, owing to be to get final product by about 1/5 of torsionspring 37 or 47 moments of elasticity that applied, so the load moment that impedance applying mechanism 40 is produced is strong excessively, Men Buhui 2 ', 3 ', 4 ' such perk as shown in phantom in Figure 6 is suitable for the door as washing machine.Have again, with Figure 16 or Figure 17 the impedance applying mechanism 40 that possesses one-way clutch 45 is illustrated, but because additional load moment is little, even adopt the structure of saving one-way clutch 45, only increase the tensile force Fo of door slightly, also have the effect that can make designs simplification.
Secondly, the wedge-shaped part to the hinge root describes.
From Figure 18 to Figure 20 is near the figure that shows the root hinge 9 at back door 3, the send as an envoy to state of a standard-sized sheet of diagram.Concerning washing machine of the present invention, owing to 2 possess guidance panel 100, so when indicating operation such as washing or drying the operator, press...with one's finger and press the action at Qianmen 2 at the Qianmen.The state of door standard-sized sheet before and after make since in the position of the guide roller on the Qianmen 28 near the rotating fulcrum 9 at back door 3, so the rigidity deficiency of guidance panel 100 is press...withing one's finger when pressing Qianmen 2, be easy to make a displacement rearward with the reaction force of hand.Be explained with Figure 18-Figure 19, in case the operator uses the words of finger to arrow Fsw direction pressing operation panel 100, Qianmen 2 and back door 3 just clockwise rotate to illustrated around the fulcrum 9 at back door, guide roller 8 upward, the direction that is arrow F8 moves, the top of guide rail 21 upwards pushed away, make it as 21T among Figure 19, to be out of shape.Therefore, because the front and back door swings to the rear, so as operator's impression, the rigidity of feeling door reduces and unstable.
In the present embodiment, as shown in figure 20, the state of 2 standard-sized sheets at the Qianmen, guide roller 8 contacts with guide rail 21, since at the back door 3 rotating fulcrum 9 make the most nearby face for for example make in guide roller 8 sides inclination angle ε=30 ° or=45 ° inclined plane 60, and make inclined plane 60 with and the bottom surface 21b of guide rail 21 design with same parts one, so guide roller 8 is at the Qianmen 2 when opening entirely, locate near the wedge shape that forms the acute angle of 2 faces by above-mentioned inclined plane 60 and guide rail bottom surface 21b, and because above-mentioned inclined plane 60 and guide rail bottom surface 21b are located on the same parts jointly, so the distortion when the state of operation person who opens at Men Quan press...withes one's finger guidance panel 100 is little, is suitable for increasing rigidity.
