Below in conjunction with accompanying drawing, the utility model embodiment rotary drum washing machine is described in detail.
Embodiment one
The present embodiment is a kind of rotary drum washing machine, as Figure 1-Figure 4, comprise interior bucket 1, interior bucket ladle body 101 is without apopore, the non-shaft core position place at interior bucket 1 position on the lower side is provided with water discharge outlet 103, water discharge outlet 103 place is provided with centrifugal draining valve 2, and centrifugal draining valve 2 comprises: bearing, upper connecting rod 201 and lower link 204.
Wherein, bearing is fixed on the lateral wall of interior bucket ladle body 101, and bearing is provided with upper and lower fulcrum.The upper end of upper connecting rod 201 is connected with balancing weight 202, and middle part and the upper fulcrum 208 of upper connecting rod 201 are hinged, and the lower end of upper connecting rod 201 is provided with slide block 203.Middle part and the lower fulcrum 209 of lower link 204 are hinged, and the lower end of lower link 204 is connected with spool 205.Upper-end part of driving and slide block 203 contact free of lower link 204 are arranged, and the bearing near upper fulcrum 208 is provided with limiting structure 211, and this limiting structure 211 makes the maximum centrifugal radius of balancing weight 202 be not more than the centrifugal radius of fulcrum 208.When interior bucket 1 is static, spool 205 closes water discharge outlet 103.
In the present embodiment, limiting structure 211 makes the maximum centrifugal radius of balancing weight 202 be not more than the centrifugal radius of fulcrum 208, setting like this can make connecting rod 201 rotary motion can not cross its vertical vertical direction, the coincidence phenomenon of upper and lower connecting rod and whole linkage now can be avoided to occur the generation of dead point phenomenon, ensure the exploitativeness of whole draining valve.
The operation principle of the centrifugal draining valve that the present embodiment provides:
When interior bucket 1 is in initial rest state, as shown in Figure 2 and Figure 4, under the Action of Gravity Field of balancing weight 202, balancing weight 202 is at its initial rest state, slide block 203, to lower support lower link 204, makes spool 205 closely be filled in water discharge outlet 103, namely, under the supporting role of linkage, spool 205 and water discharge outlet 103 closely cooperate.Wherein the initial rest state of balancing weight 202 is: under the effect of linkage Equilibrium state, make balancing weight 202 relative to being in minimum centrifugal radius place himself, such as, the initial rest state of balancing weight 202 can be close to interior bucket ladle body 101 lateral wall, certainly, also can under limiting structure 211 act on, lateral wall balancing weight 202 being limited in interior bucket 101 leaves gap.
When interior bucket 1 starts rotary motion, balancing weight 202 moves to the direction away from interior bucket ladle body 101 under the influence of centrifugal force, thus drive upper connecting rod 201 to rotate around upper fulcrum 208, the support force of slide block 203 pairs of lower links 204 is made to reduce or eliminate completely, when upper connecting rod 201 touches limiting structure 211, upper connecting rod 201 will move to its extreme position, such as, can be the vertical erectility of upper connecting rod 201, now the centrifugal radius of balancing weight 202 reaches maximum; Meanwhile, spool 205, under the acting in conjunction of hydraulic pressure and centrifugal force, also departs from water discharge outlet 103 gradually and outwards moves, thus drive lower link 204 to rotate around lower fulcrum 209, until spool 205 is in unlatching (opening) state completely.This kind of version, water in interior bucket 1 produces downward pressure to spool 205, contribute to the unlatching of spool 205, therefore only need the rotating speed that interior bucket 1 is lower, balancing weight 202 can be made to depart from the lateral wall of interior bucket ladle body 101, and make spool 205 depart from water discharge outlet 103, realize spool 205 breakdown action, as shown in Figure 3, the unlatching reliability of spool 205 is made to strengthen.
When interior bucket 1 stops operating, balancing weight 202 will slow down until static, in this moderating process, balancing weight 202 is under himself Action of Gravity Field, by self-return, connecting rod 201 is forced to rotate backward (upper connecting rod 201 starts to rotate moment rotation direction relative to interior bucket 1), until balancing weight 202 gets back to its initial rest state around upper fulcrum 208, such as, be close on the lateral wall of interior bucket ladle body 101.Meanwhile, the shaft upward sliding that the rotation returning movement of upper connecting rod 201 will force slide block 203 along lower link 201, and downward pressure is applied to lower link 204, lower link 204 is rotated backward (lower link 204 starts to rotate moment rotation direction relative to interior bucket 1) around lower fulcrum 209, spool 205 is forced to move to water discharge outlet 103 direction, until spool 205 closely extend in water discharge outlet 103, after this whole linkage will be in poised state.That is: under the Action of Gravity Field of balancing weight 202, balancing weight 202 can rotate by return easily, is closed reliably, as shown in Figure 2 and Figure 4 by linkage band movable valve plug 205 simultaneously.
As the above analysis, the draining good reliability of this centrifugal draining valve.In addition, the parts of this draining valve only need rod member (upper and lower connecting rod 201,204), jointed shaft (upper and lower fulcrum 208,209), balancing weight 202 and spool 205, daily common material can be adopted to make, not only there is the advantage that the cost of material is low, also there is the simple and processing of structure, install and be easy to advantage.
In addition, when interior bucket 1 is transformed to inactive state by motion, in order to make balancing weight 202 return more smooth, can the returning device that connecting rod 201 return can be driven to rotate be set between bearing and upper connecting rod 201, and one end of this returning device is fixedly connected with bearing, the other end is fixedly connected with upper connecting rod 201.Returning device in the present embodiment is a torsion spring 210 being arranged on fulcrum 208 position, and the arm angle of this torsion spring 210 is less than 180 °, and its opening is towards interior bucket ladle body 101; A torque arm of torsion spring 210 and upper connecting rod 201 affixed, another torque arm and bearing affixed, as shown in figs 2-4.In addition, returning device can also be chosen as extension spring or stage clip, and is fixedly connected with bearing one end of this extension spring or stage clip, and the other end is fixedly connected with upper connecting rod 201; Certainly, the returning device of other structure can also be selected.
When returning device is torsion spring 210, and when interior bucket 1 is in initial rest state, the arm angle of torsion spring 210 is in primitive nature state, without any energy storage; When interior bucket 1 rotary motion, the arm angle of torsion spring 210 will increase, and storage elasticity potential energy, rotate for driving upper connecting rod 201 return and prepare; When interior bucket 1 stops the rotation motion, under the effect of the elastic potential energy stored by torsion spring 210, torsion spring 210 can pull the rotary motion of connecting rod 201 return, now going up connecting rod 201 is that return rotates under balancing weight 202 with the acting in conjunction of torsion spring 210, clearly, upper connecting rod 201 rotates return will be more smooth and easy.In addition, utilize torsion spring 210 to carry out rotation return to upper connecting rod 201 and there is the simple advantage of structure.
In order to simplify structure, weight reduction, by upper and lower for this bearing settlement fixed bar, the angle opening that upper and lower fixed bar is formed is interior bucket ladle body 101 dorsad, and upper fulcrum 208 is positioned at the end of fixed bar 206, lower fulcrum 209 is positioned at the end of lower fixed bar 207, as shown in figs 2-4.This kind of structure can not only realize all functions of this bearing, also obviously alleviates himself weight, thus can reduce the rated power driving interior bucket 1 to rotate, and reduces energy consumption, is beneficial to environmental protection.
Concrete, when interior bucket 1 is static, in order to ensure the installation steadiness of spool 205, arrange vertical with lower link 204 for the upper connecting rod 201 during this state.When so arranging, on, force direction between lower link is perpendicular to lower link 204, and coincide with upper connecting rod 201, thus the larger support moment of guarantee effect on lower link 204 and act on the zero moment of connecting rod 201, lower link 204 can not produce turning moment to upper connecting rod 201, the stability of connecting rod 201 in guarantee, accordingly, 201, upper connecting rod can be stable support lower link 204 be in stable state, avoid crossing senior general's spool 205 due to hydraulic pressure and extrude water discharge outlet 103, thus make whole linkage more stable, ensure the functional reliability of this draining valve.
Concrete, the centrifugal radius of upper fulcrum 208 can be arranged to the centrifugal radius being greater than lower fulcrum 209, this kind of vibrational power flow can make spool 205 in opening process, and its movement travel is the shortest.
In the present embodiment, when interior bucket 1 changes into inactive state by motion state, balancing weight 202 contacts with the lateral wall of interior bucket ladle body 101, bucket ladle body 101 pairs of balancing weights 202 position-limiting actions now.Spool 205 On/Off realizes mainly through the rotary motion of balancing weight 202, therefore the weight of balancing weight 202 not easily kicks the beam, and balancing weight 202 can be chosen as steel ball, and this steel bag is wrapped with cushion.The steel ball of large density, small size has larger quality, can produce comparatively Great inertia power, can certainly adopt the balancing weight 202 of other high density materials.In addition, due to interior bucket 1 stop the rotation time, again return is close on the lateral wall of interior bucket ladle body 101 by balancing weight 202, excessive impulsive force is applied in order to prevent balancing weight 202 internal bucket 1 in return process, the weight of balancing weight 202 is unsuitable excessive, or at steel ball outer wrapping cushion, when steel ball touches interior bucket ladle body 101 lateral wall, play cushioning effect, reduce the collision even eliminating the internal bucket ladle body 101 of steel ball, the quality of bucket ladle body 101 and service life in effective guarantee, can certainly at the corresponding position of interior bucket ladle body 101 lateral wall parcel cushion pad, the same effect playing buffering and protection.
When slide block 203 contacts with the upper-end part of driving of lower link 204, frictional force can be produced, for reducing this frictional force, slide block 203 is set to roller structure, slide block 203 can be made with it to roll in the respective rods of lower link 204, make the process of linkage band movable valve plug 205 On/Off lighter, smooth and easy.
In the present embodiment, spool 205 can adopt rubber stopper, and this kind of material cost is low and common, can certainly adopt the material that other and quality of rubber materials are similar to.
In addition, in order to the convenience that the completeness and spool 205 that ensure draining are opened, in the present embodiment, as shown in Figure 1-Figure 3, water discharge outlet 103 can be located at the delivery position place of at the bottom of interior bucket ladle body 101 and interior bucket bucket 102.Other positions of interior bucket 1 partial below can certainly be located at, such as: at the bottom of interior bucket ladle body 101 lower edge position place or interior bucket bucket 102 non-shaft core position place.
In addition, in the present embodiment, interior bucket 1 adopts and arranges without apopore, thus the object that in realizing, bucket 1 is separated with outer barrel 3, as shown in Figure 1, when washing of drum type washing machine, its wash liquid is all positioned at bucket 1, avoid in conventional washer the waste of water when being communicated with between bucket 1 with outer barrel 3, in addition, because interior bucket 1 is separated with outer barrel 3, when draining, only can treat removal waste fluid in the bottom storage of outer barrel 3, therefore the height of outer barrel 3 can be reduced, clearly, not only save the installing space of washing machine entirety, also save the materials of outer barrel 3, reduce cost.
In sum, this centrifugal draining valve not only has the advantage of draining good reliability, also has the advantage that structure simply, is easily processed, easy to assemble and cost is low, and can reduce the difficulty of processing of interior bucket bucket bottom die; Therefore this rotary drum washing machine has the advantage of the low and water saving of draining good reliability, cost.
