The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the damper that utilizes thermal deformation that foundation the present invention is proposed and have its specific embodiment of washing machine, structure, feature and the effect thereof of this damper, describe in detail as after.
See also Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, Fig. 3 is the damper profile that utilizes thermal deformation of one embodiment of the invention, and Fig. 4 is the waist enlarged drawing of Fig. 3, and Fig. 5 and Fig. 6 are respectively the profiles of key diagram 3 effects.The identical part of all and above-mentioned prior art schematic structure is considered that the facility in the drawing explanation will be used identical symbol, and is omitted the detailed description to this.The present invention utilizes the damper of thermal deformation and has the washing machine of this damper, and it mainly comprises damper 40: by the cylinder 41 that alongst forms the open receiving space of an end; The overlapping inner side of said cylinder that is inserted into of one end makes it can alongst make the piston rod 45 of relative motion; Be formed in cylinder 41 and the piston rod 45 rubbing surface 42 on any one; The friction material 51 that is arranged on the rubbing surface 42 and can CONTACT WITH FRICTION; The heat deformable material 53 that thermal deformation makes rubbing surface 42 and friction material 51 be in contact with one another and moves takes place; And heat above-mentioned heat deformable material 53 and make above-mentioned heat deformable material 53 that the heating part 57 of thermal deformation take place with variation of temperature.
Below, be example with operating position in the interior drum washing machine of damper in washing machine of this thermal deformation, countercylinder 41 is connected casing 11 with can doing relative motion, and piston rod 45 can be made motion ground and connect as one with urceolus 21, is explained as follows.
Piston rod forms the bar-like shape with external diameter littler than cylinder 41 internal diameters, and the one end is formed with connecting hole, and this connecting hole connects as one it movably with urceolus.
In addition, heat deformable material 53 forms toroidal, and can be flexible along circumferencial direction.Damper structure of the present invention, it has to form with memorial alloy friction material 51 that thermal deformation has under the first low relatively temperature and the first diameter D1 of rubbing surface 42 mutual CONTACT WITH FRICTION can take place, and has the second diameter D2 less than the first diameter D1 that friction material 51 moves from rubbing surface 42 under second temperature more higher than first temperature.The outside of heat deformable material 53 falls in and is formed with insertion groove 55 and makes friction material 51 insert wherein and be supported.
Because said structure, inner core 22 rotates then and produces vibrations on the urceolus 21 during as if dehydration, and the piston rod 45 that is connected urceolus 21 is done relative motion with urceolus 21 countercylinders 41.At this moment, for the fixing heat deformable material 53 of the length direction of piston rod 45, as shown in Figure 5, because have the first diameter D1 of preceding first state of temperature of thermal deformation, friction material 51 contacts with certain frictional force with rubbing surface, therefore can relax the vibrations of urceolus 21.
In addition, reach normal dewatering speed if the rotary speed of inner core 22 increases, then not shown control part applies power supply and 57 makes heat hot deformable material 53 in the heating part.As shown in Figure 6, if heat deformable material 53 is heated and reaches second temperature, thermal deformation then takes place make internal diameter narrow down to the second diameter D2, thereby so friction material 51 move the vibrations of controlling urceolus 21 from rubbing surface 42 and be communicated to casing 11 by piston rod 45 and cylinder 41.
See also Fig. 7, Fig. 8, Fig. 9 is shown in Figure 10, Fig. 7 is damper profile that utilizes thermal deformation of this clearly demarcated other embodiment, Fig. 8 is the waist enlarged drawing of Fig. 7, Fig. 9 and Figure 10 are respectively the drawings that cuts open of the key diagram 7 damper effect that utilizes thermal deformation.Shown in Fig. 7,8,9,10, utilize this damper 60 of thermal deformation, it comprises that an end is connected casing 11 with can doing relative motion, its inboard is formed with the cylinder 61 of the drum of rubbing surface 62; The one end can be made motion ground and connect as one with urceolus 21, and the piston rod 65 of relative motion is made in the inboard that the other end is inserted into cylinder 61 with certain depth; Be arranged on the friction material 71 that rubbing surface 62 can CONTACT WITH FRICTION; Be arranged between friction material 71 and the piston rod 65 and can stretch, the bimetallic material 73 of thermal deformation takes place when applying electric current along circumferencial direction.
One end of cylinder 61 and piston rod 65 is formed with connecting hole 63,66 respectively, make and be connected respectively to casing 11 and urceolus 21, the entrance area of cylinder 61 possesses guiding section axle bush 64 is arranged, and this guiding section axle bush 64 slides when contacting cylinder 61 and piston rod can seal the slit.
In addition, bimetallic material 73 is two kinds of metal 74a that thermal coefficient of expansion has nothing in common with each other, 74b engages and to make it possible to along circumferencial direction flexiblely for one forms the annulus section shape, and its outside falls in and is formed with insertion groove 75 and it can be accommodated support friction material 71.
The outside, inserting side of piston rod 65, be formed with corresponding to bimetallic material 73 width, and falling in the bimetallic material resettlement section 67 that prolongs along circumferencial direction with certain depth along radial direction, this bimetallic material resettlement section 67 can be accommodated and be supported bimetallic material 73 with fixed support on the length direction and along circumferencial direction generation thermal deformation.The inboard of bimetallic material resettlement section 67 possesses having heaters 77 makes it can add thermal bimetal material 73.
According to said structure, inner core 22 begins to rotate and takes place to apply power supply in heater 77 than the initial stage of big bang when dehydration.As shown in Figure 9, if applying power supply reaches first temperature in heater 77 bimetallic materials 73, then bimetallic material 73 its internal diameters increase to the first diameter D1, thereby make friction material 71 and rubbing surface 62 mutual CONTACT WITH FRICTION can relax the vibrations of urceolus 21.
In addition, if the speed of inner core 22 is increased to normal dewatering speed, then the power supply of heater 77 can be broken.As shown in figure 10, if power supply will be had the second diameter D2 less than the first diameter D1 by the bimetallic material 73 then of breaking, therefore friction material 71 moves from rubbing surface 62, thereby the vibrations that can control urceolus 21 are communicated to casing 11 by piston rod 65 and cylinder 61.
In above-mentioned and illustrated embodiment, be to form rubbing surface with inboard to make that heat deformable material is the example explanation with the mobile structure of piston rod at cylinder, still, also can be on piston rod, to form the structure that the rubbing surface cylinder supports heat deformable material.
And, in above-mentioned and illustrated embodiment, be to be the example explanation with the structure that cylinder and piston rod are connected to casing and urceolus, still, also can be that cylinder is connected to the structure that urceolus is connected to piston rod casing.
The present invention that above-mentioned structure like this constitutes utilizes the damper of thermal deformation and has the technological innovation of the washing machine of this damper, all has many saving graces for technical staff of the same trade now, and the progressive that possesses skills really.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention above any simple modification, equivalent variations and modification that embodiment did.
