Abstract
The utility model relates to an engaging and disengaging gear for washing machines. The engaging and disengaging gear for washing machines is characterized in that a dehydration drum under an impeller is internally connected with an air chamber which is movably sheathed on a spindle; the closed surface of the air chamber is fixed with a covered bowl; the inner side surface of the bottom margin of the covered bowl is provided with an inner gear; the spindle in the cavity of the covered bowl is fixed with an outer gear. The utility model adopts the structural form of the floating air chamber, the covered bowl, the inner gear and the outer gear and makes use of the buoyancy of water to realize an engaging and disengaging function. Therefore, the utility model has the advantages of engaging and disengaging reliability, simple structure and lowered cost.
Description
The utility model is the washing machine arrangement of clutch, is the improvement to existing washing machine arrangement of clutch structure.
The power drive system of existing automatic washing machine as shown in Figure 1; During washing, motor drives belt 3 through driving wheel 2 rotation is reached follower 4, passes to impeller 6 by speed-reducing clutch 5, and the impeller rotation realizes washing function.During dehydration,, impeller and dehydration barrel are rotated at a high speed, dewater, during braking, rely on the mechanical brake device on the speed-reducing clutch 5 to brake by speed-reducing clutch 5.But above-mentioned speed-reducing clutch exists complex structure, cost height (about 200 yuan), and occupy shortcomings such as space.
The purpose of this utility model is in order to solve the problem of above-mentioned existence, a kind of washing machine arrangement of clutch to be provided.It can realize simplified structure, and purpose such as reduce cost.
In order to achieve the above object, connect an air chamber in the dehydration barrel that is characterised in that below impeller of the present utility model, a teabowl with a cover is fixed in being sleeved on the main shaft of air chamber activity on the air chamber sealing surface, medial surface is provided with internal gear on the teabowl with a cover base, is fixed with external gear on the main shaft in the teabowl with a cover chamber.
The air chamber outmost turns is airtight air cavity, and remainder is the air cavity of opening below.
The utlity model has the long-pending effect of following advantage: 1, save former clutch speed reducer, reduced cost (about 200 yuan); 2, save the space and be beneficial to the washing machine small design.
Fig. 1 is existing dynamical system in washer schematic diagram;
Fig. 2 is the utility model profile when being in the washing state;
Fig. 3 is the utility model profile when being in dewatering state;
Fig. 4 is that A of the present utility model is to view.
1 motor; 2 driving wheels; 3 belts; 4 followers; 5 clutch speed reducers; 6 impellers; 7 dehydration barrels; 8 external gears; 9 main shafts; 10 air chambers; 12 teabowls with a cover; 14 nuts; 15 outer buckets; 16 air cavitys; 17 internal gears; 18 airtight air cavitys.
Referring to Fig. 2, Fig. 3, Fig. 4, air chamber 10 is connected with dehydration barrel 7, and air chamber 10 is circles, and its diameter equates with dehydration barrel 7 internal diameters.Air chamber 10 outer rings are the airtight air cavitys 18 of a circle, and remainder is the air cavity 16 that one side is opened.The effect of air cavity 16 and airtight air cavity 18 mainly is in order to produce bigger buoyancy.Air chamber 10 is sleeved on the main shaft 9, and is gapped between air chamber 10 and the main shaft, and air chamber 10 is risen and fallen up and down.Fix a teabowl with a cover 12 on air chamber 10 sealing surfaces, it is " bowl " shape, and upside-down mounting is on air chamber 10.Be provided with internal gear 17 in inboard, teabowl with a cover 12 base, be fixed with external gear 8 on the main shaft 9 in teabowl with a cover 12 chambeies.
During washing, inject water between dehydration barrel 7 and the outer bucket 15, rely on air chamber 10 just to make dehydration barrel 7 float, the internal gear 17 of teabowl with a cover 12 is thrown off with external gear 8.9 runnings of driven by motor main shaft are lived multiple running thereby drive impeller 6, realize washing.
During dehydration, the water between dehydration barrel 7 and the outer bucket 15 is discharged from, owing to lost buoyancy, dehydration barrel 7 descends, thereby makes the internal gear 17 of teabowl with a cover 12 be in engagement with external gear 8.Driven by motor main shaft 9 rotates, and rotates simultaneously with dehydration barrel 7 thereby make teabowl with a cover 12 drive air chamber 10, and impeller 6 is rotation simultaneously also, makes dehydration barrel 7 realize dehydrating function.During braking, employing be brshless DC motor, direct electric braking.
Claims (2)
