Abstract
The utility model relates to a direct drive device of a rubbing and washing type for a washing machine, which comprises a planetary wheel decelerating clutch, a stirring washing shaft 24, a hollow dehydration shaft 25 and a motor which is coaxially connected with the hollow dehydration shaft. A reversal double-ratchet mechanism comprises a double-ratchet 8 arranged in a reversal mode, two staggered pawls 9 and a double-pass clutch mechanism, a clutch spring 7 is connected with the double-ratchet, the reversing rotation of the double-ratchet can make the spring reversely open and close so as to control the connection of a clutch input shaft 28 and a clutch output sleeve 13, thereby, the washing and the dehydration are controlled. When in washing, a stirring wheel and a dehydration bucket are simultaneously rotated, and the sufficient washing power is obtained by strengthening water flow rotation.
Description
Washing machine scrubbing type direct drive unit of the present utility model relates to a kind of clutch driving unit of washing machine.
The clutch driving unit pattern of washing machine has two kinds at present, and a kind of is that motor separates with clutch, uses belt transmission, its clutch band reducing gear, and complex structure easily produces uneven and big noise; Another kind is that motor and clutch coaxial connect together, and directly drives, and its motor is a variable speed electric motors, particularly, and structure is simpler, is difficult for producing uneven and big noise.But because their speed-reducing clutch is to control washing shaft and dehydrating shaft respectively, promptly the time has only washing shaft band stirring wheel then dehydrating shaft and dehydration barrel are motionless in laundry, washing shaft and dehydrating shaft one run up during dehydration, the current that are used to wash when laundry can only lean on the rotation of stirring wheel to produce like this, thereby can not obtain sufficient washing force, be difficult for cleaning clothes.
The purpose of this utility model provides a kind of simple in structure, makes and installs all very easily, can obtain the fully washing machine scrubbing type direct drive unit of washing.
Washing machine scrubbing type direct drive unit of the present utility model includes the planetary gear speed-reducing clutch, braking hub and motor and the stirring washing shaft and the hollow dehydrating shaft that connect with them, clutch output cover is connected with the braking hub, the braking hub links to each other with hollow dehydrating shaft again, the output cover comprises planetary gear speed-reducing clutch power shaft, there is oiliness bearing to be separated by therebetween, this motor shaft is connected with hollow dehydrating shaft is coaxial with the stirring washing shaft, it is characterized in that: the ratchet mechanism of this planetary gear speed-reducing clutch is an oppositely two ratchet mechanism, two ratchets and two ratchets that are in staggered positions of comprising reverse installation, and the clutch of control ratchet action, be connected with a clutch spring in two ratchets, two ratchet backward rotation make the reverse folding of spring, shaft coupling on motor shaft and planetary gear speed-reducing clutch power shaft and planetary gear speed-reducing clutch output cover are subjected to clutch for clutch control simultaneously, moving according to laundry and dehydration of the push rod that is connected with the washing machine tractor in the described clutch has two strokes, the fork that is connected with push rod is the C font, on the adjustment screw of a control push rod stroke and the ratchet of two staggered positions are arranged.
The rotor of this motor is recessed circle, and the ratchet mechanism of planetary gear speed-reducing clutch is hidden in the recessed circle of motor rotor, and lower house and bottom end cover that stator is connected on the upper shell are fixed, and the bottom end cover center has a shrinkage pool to keep ball bearing supporting motor rotor.
The another kind of situation of washing machine scrubbing type direct drive unit of the present utility model is that motor shaft and planetary gear speed-reducing clutch power shaft are same axle, near clutch output cover place the shape that matches with the shaft coupling endoporus is being arranged.
Washing machine scrubbing type direct drive unit of the present utility model is owing to adopt the oppositely two ratchet mechanisms of planetary gear speed-reducing clutch, ratchet is pushed down two ratchets of reverse installation under the normality, the clutch spring reverse opening that connects in two ratchets, shaft coupling on motor shaft and planetary gear speed-reducing clutch power shaft and planetary gear speed-reducing clutch output cover unclamp simultaneously, push rod on the brake moves according to laundry and dehydration two strokes, when first stroke action, brake band on the take-off the brake hub also enters the laundry state, but ratchet does not leave two ratchets, the trip is regulated by adjustment screw, make the output cover be in free state with hollow dehydrating shaft, when motor drives stirs the washing shaft laundry, the current of washing produce and drive the dehydration barrel rotation by the rotation of stirring wheel, the rotation of current is strengthened, thereby obtain sufficient washing force, when brake continues the brake band on the take-off the brake hub during in second stroke action and enters dewatering state, ratchet leaves two ratchets, two ratchets make the clutch spring hold shaft coupling and planetary gear speed-reducing clutch output cover simultaneously tightly in clutch spring action turning down, make motor drives stir washing shaft and enter dewatering state together by this clutch spring drive output cover and hollow dehydrating shaft, this is simple in structure, makes and installs all very easily.
Below in conjunction with accompanying drawing washing machine scrubbing type direct drive unit of the present utility model is described in more detail.
