Abstract

The utility model discloses a novel direct-drive clutch washing machine, which adopts the motor direct drive. A wave wheel shaft is directly connected with a motor output shaft; the motor output shaft is covered with a rotating shaft bush; the rotating shaft bush is fixedly connected with a washing drum for synchronous rotation; a floating clutch mechanism is also arranged with two working states: in the dehydration state, the floating clutch mechanism drops and is meshed with both the motor output shaft and the rotating shaft bush so as to achieve the synchronous rotation of the output shaft and the rotating shaft bush and drive the washing drum to rotate and be in the washing state, the floating clutch mechanism floats and is unconnected with the motor output shaft. The washing machine, compared with the direct-drive washing machine with a plurality of output shaft motors, has the advantages of simple structure, simple manufacturing process and low cost.

Description

A kind of washing machine of novel direct drive clutch
Technical field:
The utility model relates to the washing machine technical field, relates to a kind of washing machine that utilizes buoyancy of water to realize directly expelling the novel direct drive clutch of closing specifically.
Background technology:
The direct driving motor that existing washing machine uses mostly is the DD motor of international major company productions such as Japan, and this motor generally has the multi-output shaft structure, connects the parts of needs rotations such as impeller and cylindric washer respectively, and its clutch function is realized by motor internal mechanism.This complex structure, manufacture craft require high, and control is complicated, the cost height, and domestic still do not have a stable production.
The utility model content:
For overcoming the defective of prior art, the utility model aims to provide a kind of washing machine of novel direct drive clutch, and the washing machine of this structure has the Energy Efficiency Ratio height, and noise is low, vibrates advantages such as little.
The technical solution of the utility model is achieved in that
A kind of washing machine of novel direct drive clutch adopts motor direct-drive, and the impeller axle directly connects firmly with motor output shaft, is set with rotary sleeve on the output shaft of motor, and described rotary sleeve and cylindric washer connect firmly and rotation synchronously;
And floating type clutch is set, described floating type clutch has two duties:
Under the dewatering state, floating type clutch falls and is connected with a joggle jointly with the output shaft and the rotary sleeve of motor, rotates and drive the cylindric washer rotation synchronously to realize dehydration to realize output shaft and rotary sleeve.
Under the washing state, floating type clutch floats and is in the state that disengaging is connected with the output shaft of motor, and output shaft only drives the impeller rotation;
On described motor output shaft, also can be set with fixed hub, described fixed hub place between output shaft and the rotary sleeve and with they concentrics, fixed hub is fixedlyed connected with the base of motor, and bucket was fixing not with the current transfer in fixed hub was used in and makes under the washing state.
Described floating type clutch is sleeved on the output shaft by sliding shaft sleeve or on the fixed hub, this floating type clutch totally is the bowl-shape of back-off, and when injecting water in cylindric washer, the inside of floating type clutch forms seal air cavity.
The engagement system of floating type clutch and output shaft and rotary sleeve is the profile of tooth engagement.
Beneficial effect: suit rotary sleeve on motor output shaft, the come-up and the motion of falling by floating type clutch realize engaged transmission.Under the washing state, when it floats and output shaft break away from engagement, thereby have only impeller to rotate; Under the dewatering state, when it falls and output shaft and rotary sleeve be connected with a joggle simultaneously, output shaft driven rotary axle sleeve rotates synchronously, thereby being rotated at a high speed, cylindric washer realizes dehydration, this washing machine is with respect to the washing machine that uses the multi-output shaft motor, simple in structure, manufacture craft is simple, and cost is low.
Description of drawings:
Fig. 1 is a washing machine washing state profile.
Fig. 2 is the laundry machine dehydration state profile.
Fig. 3 is the structural representation of floating type clutch.
Fig. 4 is the structural representation that axle sleeve cooperates with output shaft.
Number in the figure: 1, motor, 2, output shaft, 3, rotary sleeve, 4, cylindric washer, 5, urceolus, 6, impeller, 7, floating type clutch, 7A, go up engaging tooth, 7B, engaging tooth down, 7C, seal air cavity, 7D, sliding shaft sleeve, 8, fixed hub.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The specific embodiment:
Embodiment: referring to Fig. 1-Fig. 4, in the present embodiment, the impeller 6 of washing machine is fixedly connected on the output shaft 2 of motor 1, on output shaft, be set with rotary sleeve 3 with its concentric, it and cylindric washer 4 connect firmly and rotate synchronously, also be provided with floating type clutch 7, it can move up and down according to washing state or dewatering state, makes the optionally collaborative work of cylindric washer and impeller; Under dewatering state, floating type clutch whereabouts and while output shaft and the rotary sleeve with motor is connected with a joggle simultaneously, rotates to realize dehydration to realize the rotation synchronously of output shaft and rotary sleeve and to drive cylindric washer.Under the washing state, floating type clutch floats and is in the state that disengaging is connected with the output shaft of motor.Floating type clutch is sleeved on output shaft 2 or the fixed hub 8 by sliding shaft sleeve 7D, and described fixed hub 8 is sleeved on outside the output shaft, and it and is fixedly connected on the base of motor between output shaft and rotary sleeve.Be all enclosed construction between output shaft and the fixed rotating shaft and between fixed rotating shaft and the rotating shaft.The specific embodiment and operation principle are as follows, Fig. 1 is the washing state, in the time of in water injects cylindric washer 4, all be full of water in the cylindric washer and between cylindric washer and the urceolus 5, because floating type clutch is the bowl-shape of back-off generally, can form seal air cavity 7C in the bowl this moment, because the acting in conjunction of buoyancy of water and seal air cavity internal gas pressure, floating type clutch 7 come-ups, the last engaging tooth 7A on its top and output shaft 2 break away from engagement, and following engaging tooth 7B of its underpart and rotary sleeve are in engagement or disengaged position all can, after water filling finishes, electric motor starting, output shaft drive the impeller rotation and cylindric washer does not rotate, or cylindric washer is because the impact of water has rotation slowly.(when fixed hub is installed, this at present engaging tooth should simultaneously be in engagement simultaneously with fixed hub and rotary sleeve, cylindric washer does not rotate to realize impeller to rotate), after also draining is finished in washing, dewatering state figure referring to Fig. 2, floating type clutch is because the effect whereabouts of self gravitation, the last engaging tooth 7A on its top and output shaft 2 engagements, the following engaging tooth 7B and the rotary sleeve 3 of its underpart also mesh, (when fixed hub is installed, this at present engaging tooth should break away from fixed hub and only mesh with rotary sleeve, to guarantee that rotary sleeve can rotate), electric motor starting, output shaft rotates at a high speed, and the transmission by floating type clutch, rotary sleeve also rotates synchronously, because cylindric washer fixedlys connected with rotary sleeve, thus cylindric washer also rotate with the output shaft synchronous high-speed, thereby reach the purpose of dehydration.
