Embodiment

To introduce the specific embodiment of the present invention in detail now, its example is shown in the drawings.Whenever possible, be denoted by like references same or analogous parts in the accompanying drawing all the time.

Accompanying drawing illustrates the member relevant with the motor of washing machine.Yet the present invention is not necessarily limited to the motor of washing machine.In addition, the present invention relates to a kind of household electrical appliance of using this motor, but these household electrical appliance are not limited to washing machine.

Describe motor in detail referring now to Fig. 1 and Fig. 2 according to a preferred embodiment of the invention.

Fig. 1 illustrates the stereogram according to the stator of the motor of a preferred embodiment of the invention, and Fig. 2 illustrates the stereogram according to the rotor of the motor of a preferred embodiment of the invention.

With reference to figure 1 and Fig. 2, this motor comprise have stator core 110, the stator 100 of upper insulator 120 and lower insulator 130, and rotor 200 with rotor frame 210 and permanent magnet 216.

To describe stator core 110 in detail now.

With reference to figure 1, stator core 110 comprises ring-type back of the body yoke 111, and from the radially outwards outstanding T shape thing 112 of the periphery of back of the body yoke 111.

Said stator is the stator of outer rotor-type motor, and wherein the outside of stator core 110 is provided with rotor 200.In contrast, T shape thing 112 can be radially inwardly outstanding from the inner edge of back of the body yoke 111.In this case, stator 100 is the stator 100 of inner rotor type motor.

Stator core 110 comprises lamination ring-type back of the body yoke 111, and from back of the body yoke 111 vertical outstanding T shape things 112.Back of the body yoke 111 has the caulking joint portion 113 that is used to that each layer combined and becomes one to form stator core 110.

Stator core 110 can be a multiple-level stack punching press steel plate together.Yet, owing to formed useless circular bloom etc., so waste material very likely in the inboard of stator core 111.

Therefore, preferably stator core 110 forms with spiral type, wherein will carry on the back yoke 111 and pile up from back of the body yoke 111 vertical outstanding T shape things 112 by spirality ground crooked back of the body yoke 111 and T shape thing 112.Fig. 1 illustrates this type of spiral stator core 110.

Upper insulator 120 and lower insulator 130 are installed in the upside and the downside of stator core 110.That is upper insulator 120 and lower insulator 130 are anchored on stator core 110 to encase stator core 110 and to make its insulation.

Upper insulator 120 has the winding portion 121 and 131 that is used to encapsulate from back of the body yoke 111 vertical T shape thing 112 outsides of giving prominence to respectively with lower insulator 130.The coil (not shown) is wrapped in the winding portion 121 and 131 of encapsulation T shape thing 112.Winding portion 121 and 131 insulation that keep between T shape thing 112 and the coil.

Simultaneously, upper insulator 120 and lower insulator 130 can form a unit with stator core 110.For example, stator core 110 can be arranged in before molded between insulator 120 and 130 so that upper insulator 120 and lower insulator 130 form a unit with stator core 110.Insulator 120 and 130 can comprise the dielectric film (not shown) that is arranged between the T shape thing 112.

Upper insulator 120 and lower insulator 130 have radially outstanding internally fastening boss 125 and 135 respectively.Fastening boss 125 and 135 has the fastener hole 126 and 136 that is formed on wherein respectively with fastening stator 100.Fastener hole 126 and 136 for example can be anchored on the rear surface (not shown) of the bucket of the drum type washing machine that belongs to a kind of household electrical appliance.

That is the fastener hole 126 of upper insulator 120 and the fastener hole 136 of lower insulator 130 form a fastener hole that matches each other when upper insulator 120, stator core 110 and lower insulator 130 tighten together.With the bolt (not shown) that passes this type of fastener hole whole stator 100 is anchored on bucket or analog.

Locator protrusions 127 can be formed near the fastener hole 126 of upper insulator 120.With behind stator 100 location, available aforementioned bolt is anchored on bucket with stator 100 by (not shown) in the location hole that locator protrusions 127 is arranged on bucket or analog.

Fastening boss 125 and 135 and the fasteners that constitute of fastener hole 126 and 136 can stator 100 be fixed in bucket, but be fixed in the motor bracket (not shown), perhaps the motor case (not shown).

In this case,, motor provides " support " this title based on being fixed in the purpose of household electrical appliance or analog, and based on the purpose of ccontaining motor or analog and provide " shell " this title.Yet, because a title can realize these purposes simultaneously, so said elements is called support.

For example, in motor, need be with stator 100 with respect to the fixing (see figure 2) of rotor 200.Therefore, need be used for fixing the device of stator 100, it can be pedestal 212 (see figure 2)s.

Pedestal 212 can be the support that forms the motor outside.Along with stator 100 at first be anchored on support then motor be anchored on household electrical appliance, and support is fastening or be connected to household electrical appliance.In other words, motor is anchored on household electrical appliance through support.

Simultaneously, owing to motor can be positioned in the household electrical appliance, so motor can not need support.For example, stator 100 can directly be anchored on the rear wall of bucket.Correspondingly, in this case, stator 100 fastening parts thereon, such as the rear wall of washing machine drum can be described pedestals.

The T shape thing 112 of said stator 100 has winding u, v, w phase coil thereon respectively.Under this situation, described T shape thing is included in the winding portion 121 and 131 of insulating between the T shape thing 112 of stator core 110.

In order to make a T shape thing 112 have a magnetic pole, a coil can be wrapped on the T shape thing 112, and this is called concentrated winding.The number of magnetic poles of stator 100 (that is, the quantity of T shape thing 112) is many more, and then the maximum (top) speed of rotor 200 is low more, and it makes motor be easy to control, and peak torque is big relatively more.

In case the winding of the u phase coil on one of T shape thing 112 is finished, described coil just is wrapped on the wrapping post 122 on the upper insulator 120 along with coil and is fastened, skips two T shape things 112 then and is wrapped on the next T shape thing 112.

The initiating terminal of coil is positioned at power supply respectively with the end end and is connected tap terminal 128 and neutral point tap terminal 129.For the purpose of convenient, described initiating terminal and end end are called terminal.

Power supply connects tap terminal 128 and has the connector 140 that is attached thereto three-phase electricity is acted on u, v, w phase coil respectively.All terminals of three-phase coil all are electrically connected with neutral point tap terminal 129 to form neutral point.

Under this situation, power supply connects tap terminal 128 and neutral point tap terminal 129 has the outside that is formed by insulating material, preferably becomes one with upper insulator 120.Yet the formation position that power supply connects tap terminal 128 and neutral point tap terminal 129 is not limited thereto.

Simultaneously, the side in power supply connection tap terminal 128 and neutral point tap terminal 129 is provided with aperture member fixed thereon 141.Detect after a while the position of the rotor 200 of explanation and/or voltage-phase and the current strength that speed applies with control with hole sensor assembly 141, thus the rotating speed and the moment of torsion of control rotor 200.

In wrapping post 122 inboard radially, be respectively equipped with the insulator rib 123 that is formed on upper insulator 120 and the lower insulator 130.The height of insulator rib 123 greater than predetermined altitude to block the water that flow to winding portion 121 and 131 from insulator 120 and 130 inside.

Insulator rib 123 forms the height that is higher than coil windings.Insulator rib 123 prevents that coil from damaging when handling stator 100.That is, when stator places on the ground, have only insulator rib 123 with contact, rather than coil with contact, thereby prevent the coil damage.

Rotor 200 of the present invention will be described now.

As previously mentioned, rotor 200 comprises rotor frame 210 and permanent magnet 216.

The side wall portion 211 that rotor frame 210 has pedestal 212 and forms along the periphery of pedestal 212.Can make pedestal 212 and side wall portion 211 form a unit by punching press one block plate.

Inboard at side wall portion 211 along a plurality of permanent magnets 216 circumferentially are installed.Permanent magnet 216 is along circumferentially alternately being geomagnetic into north and south poles.Thus, the effect of side wall portion 211 is as the back of the body yoke that forms magnetic circuit.

Simultaneously, can form a unit by the rotor frame 210 that injection moulding will have pedestal 212 and a side wall portion.In this case, need described side wall portion to have ring-shaped magnetic back of the body yoke 111 mounted thereto in addition.

Hub portion 213 projects upwards at the middle part of the pedestal 212 of rotor 200 to strengthen the rigidity of pedestal 212.Hub portion 213 has central through-hole 219, and for example the rotating shaft (not shown) of rotating shaft of washing machine and so on is positioned in this hole.

With connector or analog (not shown) described rotating shaft is connected with hub portion 213.Thus, along with rotor 200 rotations, revolving force transfers to described rotating shaft from rotor 200.

Hub portion 213 has the fastener hole 214 that is used for clamp connector 140, perhaps is used at first fixing the location hole 215 of the position of described connector.

Hub portion 200 is arranged in the stator 100, and owing to rotates with respect to stator 100 with the interaction of stator 100.Certainly, thus the revolving force of rotor 200 transfers to the rotating shaft that is connected with rotor frame as a unit rotation.

Simultaneously, the invention is characterized in, is not the copper coil that has adopted prior art, but has adopted the coil of aluminum core line 160b.The internal resistance of aluminium is greater than copper.Therefore, in order to reduce internal resistance, the external diameter of coil that need make aluminum core line 160b is greater than described copper coil.

The ductility of aluminium is lower than copper.Therefore, aluminium is easy to externally rupture under the percussion when twining.In addition, aluminium meet water then a little less than, particularly salt solution makes that aluminium is easy to corrode and rupture when contact with salt solution.

Therefore, in motor of the present invention, preferably aluminum coil has the deposited film of the bilayer that spreads on the aluminum core line outside to strengthen intensity and ductility.In addition, double-deck deposited film has increased the insulation property of coil.

Simultaneously, as previously mentioned, the terminal of coil is positioned at power supply respectively and connects tap terminal 128 and neutral terminal 129.This type of coil terminals needs to apply film and exposes heart yearn to be electrically connected from its removal.

Thus, as previously mentioned, it is weak and be easy to fracture that coil exposes the terminal part of heart yearn thereby intensity and ductility, and when described heart yearn and water, be easy to when particularly contact with salt solution corrode.

For example, the household electrical appliance such as washing machine, drying machine and dishwasher not only use cold water, also use hot water or hot-air.Therefore, described household electrical appliance turn round under humidity and hot environment.Therefore, have exposure heart yearn coil the terminal part intensity and the insulation particularly important in household electrical appliance.

Power supply be will describe now in detail and tap terminal 128 and neutral point tap terminal 129 connected.

Power supply connects the similar of tap terminal 128 in neutral point tap terminal 129.For example, though the terminal position that neutral point tap terminal 129 has three u, v, a w phase coil thereon, power supply connects terminal position that tap terminal 128 has only specific u, a v, w phase coil thereon.Therefore, convenient for the purpose of, neutral point tap terminal 129 is described as representative.

Will be with reference to figure 3 to 12 explanation neutral point tap terminal 129.

Fig. 3 illustrates the stereogram according to the neutral point tap terminal of a preferred embodiment of the invention, and Fig. 4 illustrates the exploded perspective view according to the neutral point tap terminal 1 of a preferred embodiment of the invention.

With reference to figure 3 and Fig. 4, be formed with space 161 in the tap terminal 129 so that MAG-MATE terminal (magmate) 150 is arranged in wherein.The front and rear in space 161 has the groove of the terminal that is used for hold-in winding 160.Preferably with the top chamfer of groove 162,163 or rounding so that coil 160 is arranged in wherein.

Simultaneously, tap terminal 129 1 sides can be connected with insulator rib 123.That is tap terminal 129 can form a unit with upper insulator 120.Yet the structure of tap terminal 129 is not limited thereto, and also can be formed on support or pedestal 212.In addition, tap terminal 129 can be exposed to the support outside so that tap terminal 129 is easy to combine with connector 140 in the support outside.

MAG-MATE terminal 150 is

Shape, and respectively forwardly 152, have groove 151 in rear portion 153 and the bottom 154.Certainly, preferably groove 151 is respectively formed at the centre of anterior 152, rear portion 153 and bottom 154.

Preferably coil 160 is forced to be arranged in and make heart yearn expose in the groove 151 and be electrically connected with MAG-MATE terminal 150.Therefore, MAG-MATE terminal 150 needs to be formed by electric conducting material.Certainly, behind the heart yearn 160b that exposes coil 160, MAG-MATE terminal 150 can be electrically connected with heart yearn 160b.

Under this situation, MAG-MATE terminal 150 can not have groove 151.That is MAG-MATE terminal 150 can have the specific part that will contact with the heart yearn 160b of coil 160, and this specific part can have formation insulation division thereon.

In order to strengthen the intensity of MAG-MATE terminal 150, the front portion 152 of MAG-MATE terminal 150 and rear portion 153 form parallel to each other, and bottom 154 forms and is orthogonal to anterior 152 and rear portion 153.In addition, MAG-MATE terminal 150 can have and is parallel to 154 top 155, bottom and integral type is

Shape.

MAG-MATE terminal 150 can have the opening opposing side, and the global shape of MAG-MATE terminal 150 can be by being bent to form in this case.In addition, MAG-MATE terminal 150 can have uncinus 156 in relative both sides.Certainly, with uncinus 156 as one man, can in the space 161 of tap terminal 129, form the depression or protruding (not shown).Thus, if MAG-MATE terminal 150 is arranged in the tap terminal 129, MAG-MATE terminal 150 is kept making MAG-MATE terminal 150 can not deviate from from tap terminal 129 easily by uncinus 156.

Under this situation, as previously mentioned, after in the groove 162 of terminal position in tap terminal 129 of coil 160, along with heart yearn in the space 161 that MAG-MATE terminal 150 is arranged in tap terminal 129 is exposed, then can finish the terminal of coil 160 and being electrically connected of MAG-MATE terminal 150.Yet described electrical connection also can expose the back at heart yearn and finish when being arranged in MAG-MATE terminal 150 in the tap terminal 129.

Simultaneously, the connecting portion of the terminal of coil 160 and MAG-MATE terminal 150 has in addition that insulation division is used for strengthening, anticorrosive and insulation.This insulation division can take various forms to form.

The tap terminal 129 that is formed with insulation division on it can be that power supply connects tap terminal 128 or neutral point tap terminal 129.Yet, for convenience of explanation, will only describe, and identical content will can be applicable to power supply connection tap terminal 128 neutral point tap terminal 129.

For example, with reference to figure 3, although neutral point tap terminal 129 has the terminal of each phase coil 160 that is attached thereto, it is the terminal of three-phase coil 160, but power supply connects the terminal that tap terminal 128 has the certain coil 160 that is attached thereto, that is, and and the terminal of a coil 160 only.Certainly, in all cases, MAG-MATE terminal 150 can have difformity, will describe after a while.

With reference now to accompanying drawing, is described in detail in the insulation division of the connecting portion of the portion of terminal of coil 160 and MAG-MATE terminal 150.

Fig. 5 illustrates the plane graph of demonstration according to the connection status of a preferred embodiment of the invention neutral point tap terminal and coil, and Fig. 6 illustrates the plane graph of demonstration according to the state of a preferred embodiment of the invention insulation division when the neutral point tap terminal is connected with coil.Being electrically connected of the terminal of the schematically illustrated MAG-MATE terminal 150 of Fig. 5 and Fig. 6 and coil 160.

Along with the heart yearn 160b of coil 160 directly contacts with the MAG-MATE terminal 150 that electric conducting material forms, MAG-MATE terminal 150 and coil terminals are electrically connected in tap terminal 129.Thus, coil 160 is in the state of removing deposited film 160a from it with the specific part that MAG-MATE terminal 150 directly contacts.

Therefore, as previously mentioned, if coil 160 is shaken or is subjected to external impact, then coil 160 probably ruptures with the heart yearn 160b that MAG-MATE terminal 150 directly contacts, and perhaps the heart yearn 160b owing to coil 160 is that aluminium corrodes.

In order to prevent that in advance this problem from occurring, the part that the heart yearn 160b that preferably described insulation division is formed on coil 160 and MAG-MATE terminal 150 directly contact.An example of insulation division is spreading resin 170 on part shown in Figure 6.

Resin 170 is an insulating material, thereby solidify to keep heart yearn 160b insulation protection heart yearn 160b not to be subjected to outer damage the coating back.Certainly, external force is cut off effect with the intensity that plays reinforced-core 160b to the direct effect of heart yearn 160b.

Although the connecting portion that insulation division is formed on MAG-MATE terminal 150 and heart yearn 160b is insulating to heart yearn 160b and to protect, resin 170 also can be filled in the space 161 of tap terminal 129 heart yearn 160b is insulated and protect.

With reference to figure 7, resin 170 is full of the space 161 of tap terminal 129 fully.That is spreading resin 170 makes resin 170 not only encase the expose portion of the heart yearn 160b of MAG-MATE terminal 150 and coil 160, and encases the part that coil 160 is not removed deposited film 160a.

In this case, although may need more resins 170, the terminal of coil 160 is fastening firmer to tap terminal 129, and can guarantee more reliable insulation, and anticorrosion more reliably.

In addition, in this case, preferably tap terminal 129 is not that power supply connects tap terminal 128, but neutral point tap terminal 129.Its reason is that neutral point tap terminal 129 does not need to be electrically connected with part outside the coil 160.

Simultaneously, connect tap terminal 128, then need MAG-MATE terminal 150 to be connected with power supply if tap terminal 129 is power supplys.For this connection, preferably power supply connects tap terminal 128 at least a portion does not have application of resin 170.

MAG-MATE terminal 150 can be other shapes to be connected with external power source.

Fig. 8 illustrates the stereogram according to the MAG-MATE terminal of the neutral point tap terminal of a preferred embodiment of the invention, and Fig. 9 illustrates the stereogram of MAG-MATE terminal of the neutral point tap terminal of another execution mode according to the present invention.As Fig. 8 and shown in Figure 9, MAG-MATE terminal 150 has connecting

portion

157 or 158 in addition to be connected with external power source.

Connecting portion 157 can be from tap terminal 128 outside parts of giving prominence to as the front portion 152 or the rear portion 153 of MAG-MATE terminal 150.Connecting portion 157 is arranged in when connector 140 (see figure 1)s are connected with tap terminal 128 in the connector 140 to be connected with external power source.

That is different with the MAG-MATE terminal 150 among Fig. 3, the MAG-MATE terminal 150 among Fig. 8 has from tap terminal 128 outside outstanding connecting portions 157 to be connected with external power source.
