Abstract
The utility model relates to a direct-driving type fully automatic washing machine. The utility model is mainly characterized in that a motor of the washing machine is coaxially and integrally fixed with a speed reducing clutch; a motor shaft is directly used as an input shaft of the speed reducing clutch, or is directly connected with the input shaft of the speed reducing clutch to drive the speed reducing clutch to run and is engaged and disengaged through an engaging and disengaging mechanism, and the separate running of an impeller and a dewatering drum is realized. Compared with the existing fully automatic washing machine, the utility model omits a belt drive system or an expensive frequency conversion motor; in addition, the equilibrium is good, and the structure simplification of the washing machine and the vibration performance improvement are realized.
Description
The utility model is a direct drive-type automatic washing machine that is used for washing clothes.
The realization of existing automatic washing machine washing, dehydrating function has following dual mode: 1, belt transmission: during washing, the motor pulley running that driven by motor is fixed thereon, pass through belt transmission, drive the belt pulley running of speed-reducing clutch, at this moment, clutch is opened, the speed-reducing clutch belt pulley drives the power shaft running of speed-reducing clutch, after slowing down, the running of axle impeller realizes washing function in the decelerator output.During dehydration, belt transmission is passed through in the motor pulley running that driven by motor is fixed thereon, drive the belt pulley running of speed-reducing clutch, at this moment, clutch closes, and the speed-reducing clutch belt pulley drives the running of decelerator outer shaft, the speed-reducing clutch outer shaft drives dehydration barrel running fixed thereon, realize dehydrating function, this structural manufacturing process complexity, cost height, the belt quick abrasion, it is big to take up room.2, variable-frequency motor transmission: during washing, variable-frequency motor is reduced to the suitable rotational speed of washing with rotating speed under the control of frequency-variable controller, and at this moment, clutch is opened, and the direct impeller running of motor shaft realizes washing function; During dehydration, variable-frequency motor is under the control of frequency-variable controller, and rotational speed regulation is to the suitable rotational speed of dehydration, and at this moment, clutch closes, and motor shaft drives the running of output outer shaft, and the output outer shaft drives dehydration barrel running fixed thereon, realizes dehydrating function.This structure technology requires high, complex process, cost costliness.
The purpose of this utility model is to overcome the weak point that prior art exists, and provides a kind of simple in structure, the direct drive-type automatic washing machine that cost is low.
Technical solution of the present utility model is: the motor of washing machine and speed-reducing clutch concentric are fixed as one, motor shaft is directly as the power shaft of speed-reducing clutch or directly connect with the speed-reducing clutch power shaft, the running of driving speed-reducing clutch, again by the clutch clutch, realize the separately running of impeller and dehydration barrel, this incorporate motor reduction clutch is connected on the washing machine with direct or indirect method.
The utility model is compared with existing automatic washing machine, removed belt drive system or expensive variable-frequency motor, and balance is good, and realize the designs simplification of washing machine and improved vibration performance, good manufacturability, cost is low.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is motor shaft and the speed-reducing clutch power shaft structural representation by key connecting.
Fig. 3 structural representation that to be motor shaft connect by shaft coupling with the speed-reducing clutch power shaft.
The motor reduction clutch structural representation of flexible member indirect securement on washing machine pedestal that Fig. 4 is integrated.
The motor reduction clutch structural representation of flexible member indirect securement on washing machine tub that Fig. 5 is integrated.
The integrated motor reduction clutch of Fig. 6 directly is fixed on the structural representation on the washing machine tub.
Below in conjunction with accompanying drawing the utility model is described in detail.
The motor and the speed-reducing clutch of washing machine are fixed together, and are concentrics, see Fig. 1, and motor 1 is fixed as one by screw 3 with speed-reducing clutch 5, and motor shaft 2 is directly as the speed-reducing clutch power shaft; Motor shaft also can become one by connecting with the speed-reducing clutch power shaft, and as Fig. 2, motor shaft 2 connects by key or spline 6 with speed-reducing clutch power shaft 4; As Fig. 3, motor shaft 2 connects by shaft coupling 7 with speed-reducing clutch power shaft 4.This incorporate motor deceleration device is fixed on the washing machine with direct or indirect method, and the integrated motor reduction clutch of Fig. 4 uses the flexible member indirect securement on washing machine pedestal 8.The integrated motor reduction clutch of Fig. 5 uses the flexible member indirect securement on washing machine tub 9.The integrated motor reduction clutch of Fig. 6 directly is fixed on the washing machine tub 9.The realization division of washing and dehydrating function is as follows: during washing, clutch is opened, the speed-reducing clutch power shaft running that motor shaft is linked together with it, or motor shaft directly drives the speed-reducing clutch gear operation as the speed-reducing clutch power shaft, after slowing-down structure slows down, the running of axle impeller realizes washing function in the speed-reducing clutch output; During dehydration, clutch closes, and motor shaft drives the running of speed-reducing clutch outer shaft, and the speed-reducing clutch outer shaft drives the dehydration barrel running, realizes dehydrating function.
