The specific embodiment
The present invention is for guaranteeing in the spin-dry program, interior drum can rotate around vertical axis, pattern with rotary drum washing machine dries, and double-mode washing machine spin dryer tube (interior drum) when program for washing finishes is braked be positioned the upright position and a kind of drum braking and positioning method of double-mode washing machine and the braking positioner of this method are provided.
The invention provides a kind of drum braking and positioning method of double-mode washing machine, described double-mode washing machine have outer steel ladle 3 and be located at interior drum 1 in the steel ladle 3 and outer drum 2 referring to Fig. 3,6, during laundry, the vertical axis 6 of interior drum 1 bottom breaks away from vertical drive, interior drum 1 and outer drum 2 jointly around horizontal rotating shaft 4 rotations, are realized the laundry of cylinder pattern under the driving of horizontal drive apparatus; During spin-dry, the vertical axis 6 of interior cylinder bottom combines with vertical drive, and under the driving of vertical drive, interior cylinder rotates around vertical axis, realizes that the impeller pattern dries; For guaranteeing that interior cylinder is after program for washing finishes, interior drum can be braked and be positioned the upright position, and the drum braking positioner is set in washing machine, in order to save braking energy, accurately control starts the pre-set time of braking positioner, is provided with a drum rotation speed sensor and cylinder position sensor.When program for washing finishes, the power source of horizontal drive apparatus is cut off, inside and outside drum relies on the inertia rotation, drum rotation speed sensor internal and external cylinder rotary speed, when the rotary speed of internal and external cylinder is lower than setting value (for example 10 rev/mins), the cylinder position sensor then detects the cylinder position of rotation, according to the cylinder position of rotation, controller is according to the rotary speed of internal and external cylinder, delayed startup drum braking positioner makes internal and external cylinder stop at the position of the vertical axis of interior drum perpendicular to ground.
Embodiment one
Described drum braking positioner is arranged on the horizontal rotating shaft 4 as shown in Figure 6.Specifically be, set firmly a braking positioning disk 31 in the outer end of horizontal rotating shaft 4, be provided with locating hole 32 in the periphery of braking positioning disk 31; One alignment pin 33, the one end cooperates with described locating hole 32, and the other end connects an electromagnet 34 by a stage clip 35.When alignment pin 33 inserted in the locating hole 32, the vertical rotation axis 6 of described interior cylinder was in position perpendicular to the ground; And described drum rotation speed sensor and cylinder position sensor can be realized with a photoelectric sensor, and described photoelectric sensor specifically is as shown in Figure 7.On the disk of braking positioning disk 31, be provided with a through hole 36, angle between the locating hole 32 on the periphery of described through hole 36 and positioning disk 31 lines of centres and positioning disk 31 and positioning disk 31 lines of centres is a fixed value α, desirable 45 °, 90 °, 135 °, 180 °, 225 °, 270 ° of α etc.One light source 37 and an optical-electrical converter 38 are set respectively in the both sides of through hole 36.The frequency of the light that passes through through hole 36 that optical-electrical converter 38/ senses is the rotating speed of inside and outside drum, can obtain the position of a certain inside and outside drum of the moment constantly according to rotating speed, α and sensitization.
During washing, the electromagnet 34 of drum braking positioner gets electric, and armature is inhaled, and drives spring 35 and alignment pin 33 motions, and the periphery that makes alignment pin 33 break away from braking positioning disks 31 is provided with locating hole 32 (as shown in Figure 6).The vertical rotation axis 6 of cylinder breaks away from vertical drive simultaneously, and inside and outside drum rotates washing around horizontal rotating shaft 4 under the driving of horizontal drive apparatus.
When program for washing finishes, the power source of horizontal drive apparatus is cut off, in, outer drum relies on the inertia rotation, drum rotation speed sensor internal and external cylinder rotary speed, when the rotary speed of internal and external cylinder is lower than setting value (for example 10 rev/mins or lower), the cylinder position sensor then detects the cylinder position of rotation, according to the cylinder position of rotation, controller is according to the rotary speed of internal and external cylinder, delayed startup drum braking positioner, make electromagnet 34 outages, electromagnet armature drives the periphery of alignment pin 33 contacts braking positioning disk 31 under the effect of spring force, locating hole 32 on braking positioning disk 31 peripheries forwards the position of alignment pin 33 to, and alignment pin 33 promptly inserts (as shown in Figure 5) in the locating hole 32, makes internal and external cylinder stop at the position of the vertical axis of interior drum perpendicular to ground.
The advantage of this structure is the time requirement that starts the drum braking positioner not strict, if arrive at locating hole 32 before the position of alignment pins 33 arbitrary time all can, and accurate positioning.Shortcoming is that braking location impulsive force is big, must be strict controlled in to start the braking positioner when cylinder is in low speed, requires alignment pin 33 thick.
Embodiment two
Fig. 7, the 8th, the another kind of the drum braking positioner of double-mode washing machine of the present invention is implemented illustration.Be with the difference of embodiment one, described brake is a disc type band-type brake electromagnetic brake 40, specifically be, in the set positioning disk in the outer end of horizontal rotating shaft 4 is brake puck 41, one arc band-type brake is located at the wheel rim side of brake puck, and described arc band-type brake 42 1 ends are fixed in the described steel ladle outside, and the other end connects electromagnet 43, also be provided with back-moving spring 44 on described arc band-type brake, the whetstone magnetic coil of described electromagnet connects controller.Be provided with through hole 36 in brake puck 41 equally, be respectively equipped with the light source 37 and the optical-electrical converter 38 of photoelectric sensor in the through hole both sides.
During washing, electromagnet 43 outages of disc type band-type brake electromagnetic brake 40, armature drives band-type brake 42 motions under the back stretch effect of spring 44, make band-type brake 42 break away from the wheel rim (as shown in Figure 8) of brake puck 41.The vertical rotation axis 6 of cylinder breaks away from vertical drive simultaneously, and inside and outside drum rotates washing around horizontal rotating shaft 4 under the driving of horizontal drive apparatus.
When program for washing finishes, the power source of horizontal drive apparatus is cut off, in, outer drum relies on the inertia rotation, drum rotation speed sensor internal and external cylinder rotary speed, when the rotary speed of internal and external cylinder is lower than setting value (for example 10 rev/mins or lower), the cylinder position sensor then detects the cylinder position of rotation, according to the cylinder position of rotation, controller is according to the rotary speed of internal and external cylinder, delayed startup drum braking positioner, it is electric that electromagnet 43 is got, and electromagnet armature drives the wheel rim that band-type brake 42 is held brake puck 41 tightly under the suction of electromagnet, makes internal and external cylinder stop at the position of the vertical axis of interior drum perpendicular to ground.
The advantage of this structure is that braking location impulsive force is little; Shortcoming is that the location is difficult for accurately, to starting the time requirement strictness of drum braking positioner, must determine to start the time of brake according to the size of rotary inertia, brake force.
For separating the accurate problem of decision bit, can respectively establish one in the both sides of optical-electrical converter 38 and proofread and correct optical-electrical converter, be used for detecting and whether put in place or cross the position, according to testing result index drum forward or reverse, the vertical axis of drum is perpendicular to ground in making.
