Description

Plane induction wave wheel washing machine

The utility model belongs to machine design manufacturing technology field, relates to a kind of low cost and the washing machine of the new type power system of better serviceability is arranged, and can be used for washing clothes by people with long service life.

Washing machine is used in the family life by people widely, existing washing machine drives impeller with the single phase ac asynchronous motor by belt pulley, the impeller axle passes and motor-driven big belt pulley axis hole connection at the bottom of wash bucket, the impeller axle need prevent to leak with water seal, under this structure situation, water in the wash bucket has bigger pressure to it, not in the Chang life cycle, bearing oil is washed away by water decomposition, rear axle heavy wear, distortion, can't use until leaking, cost is high again during replacing, this exterior belt pulley is also yielding, cause unsettled duty, and washing machine complete machine manufacturing process is many, cycle is long.

The purpose of this utility model is by changing the dynamic characteristic of existing washing machine, overcoming the deficiency of above-mentioned conventional laundry apparatus and reach better serviceability with brand-new dynamic structure.

The utility model is common alternating current generator stator, rotor launches to become a kind of electric system of flat shape, directly impeller as rotor, impeller rotor and stator lean on very closely during assembling, be separated with between them at the bottom of the washing machine drum of nonmagnetic substance, stator is in the same place with the washing machine pedestal multi pack, the major axis pipe of a top seal of axial connection of impeller rotor, be provided with bearing in the central siphon, bearing centre is by a major axis, major axis connects fixing at the wash bucket middle part, the rotating excitation field of washing machine stator generation is responded to the impeller rotor and is made the asynchronous rotation of impeller rotor across the wash bucket drain pan like this, and finish the utility model, rotor axial major axis pipe makes bearing wherein not be subjected to water erosion under gas pressure because of top seal simultaneously.Power system principle of the present utility model is consistent with common alternating current generator, and function is the same with conventional laundry apparatus with mode of operation.

The each side advantage that the utility model brought is: 1, part is few in addition, the life-span is long, repair rate is low.2, few, the energy loss of bearing, mechanical loss little, save sealing structure for water.3, impeller induction force brachium (strength is big), with the contact with clothing face width that is washed.4, the working stability performance is good.5, can be from maximizing and expense is low to microminiaturized Free Development.6, cleaning performance is good, nothing is twined, compact conformation is reasonable.

See accompanying drawing:

(1) the utility model electric system is that plane and common electric machine contrast: ring-type stator (11) ring Nei Yuan limit is equivalent to common electric machine iron core one end, ring Wai Yuan limit is equivalent to the common electric machine iron core other end, shape difference and sensed conditions unanimity, so and common electric machine difference little.The design data characteristics such as magnetic flux density of stator (11) were during this was novel: relatively common electric machine magnetic flux characteristic and coil data characteristics, increase coil turn adapting to the characteristic with balance the utility model electric system air gaps duty, its principle is that stator and rotor airgap when strengthening, magnetic flux density die down, cause that induction reactance diminishes, no-load current becomes big.Because what the refrigeration condition of the utility model motor stator (11) and rotor (10) was better, the induction coil (8) of rotor (10) can adopt wire wound.Below be an embodiment of the present utility model:

See that accompanying drawing (1) core of the present utility model is the dynamic structure of a novelty: become flat state AC single phase capacitor formula asynchronous machine, form by (8) (9) (10) (11) (24) (25), directly be that rotor, rotor are made up of (8) (10) (14) (16) with the impeller, its diameter is big, the induction force brachium.

See accompanying drawing (2), motor stator (11) with silicon guiding principle tape wrapping circlewise iron core simultaneously mill out coil groove (24), load onto coil (9) and form, ring-type iron core external diameter is that 20 centimetres, internal diameter are 10 centimetres (being diameter), wide 0.5 centimetre, high 2 centimetres of wire casing, thick 3.5 centimetres of iron core is 48 grooves.(25) for edge ring so that casting resin with the sealing coil, shield.

See that accompanying drawing (3), rotor are wound into silicon strip also that the ring-type iron core simultaneously mills out coil groove (25), interior cast alloys aluminium (8) forms, 20 centimetres of iron core external diameters, 10 centimetres of internal diameters (being diameter), thick 2 centimetres, 0.5 centimetre of groove width, high 1 centimetre are 44 grooves.Whole rotor be coated with plastic material with antirust, rotor, ring inwall be welded a steel frame cover (14), glued joint, impeller dish (16) be loaded on the rotor (10) form at last by frame cover (14) and washing machine central siphon (4).

See that accompanying drawing (4), washing machine pedestal (20) bottom are provided with air admission hole (18), be provided with air outlet (21) all around, there is mini-sized shaded pole type heat radiation motor (17) in bottom centre, stator frame (19) is for being distributed in the inner motor (17) that cooperates of base (20) sheet shape radial garden week to stator (11) heat radiation, and base (20) is provided with electric control box (23).

See accompanying drawing (5), wherein (C): the winding split-phase capacitor, get 10 microfarads, withstand voltage 400V (K1) is a motor direction of rotation change-over switch, (K2) be unidirectional, two-way operation selector switch, (K3) be power switch, (K1) (K3) establishes parts in the mechanical timer.
