Description
Technical Field
The present invention relates to a fixing structure of motor for washing machine. More particularly, the present invention relates to a fixing structure of a motor, which facilitates securing an installation space of the motor by shortening an assembling process and reducing an overall size of the motor by improving an assembling structure of a fixing bracket of the motor for fixing the motor driving a drum of a washing machine or dryer with the motor.
Background
Generally, a washing machine or dryer includes: a rotary drum having a cylindrical shape for accommodating laundry; and a motor connected to the rotary shaft behind the rotary drum via a belt to drive the rotary drum. Such a motor needs to be fixed to a body of a washing machine or dryer, and a housing or bracket for fixing the motor is made of aluminum or bulk molding compound (BMC, bulk Molding Compound) resin. In the case of using aluminum, since noise or vibration occurs at a motor fixing portion and material costs are high, a bulk molding compound resin has recently been applied to a motor housing and a bracket. Under the condition of using bulk molding compound resin, the method has the advantages of obvious small noise and vibration and strong moisture resistance.
In a state where a fixing bracket formed of a bulk molding compound resin and a motor housing are fastened in a motor using the bulk molding compound resin, the fixing bracket is provided inside a washing machine body so that a drum is stably driven by a belt in a state where the motor is supported by the fixing bracket, which is representatively disclosed in korean patent No. 10-1707142. According to this prior art, a coupling hole is drilled in the lower surface of the motor housing, and fastening is performed with the coupling hole by means of a coupling bolt through a fixing hole formed in the first bracket and the second bracket, thereby fixing the bracket supporting the motor to the motor.
However, since the screw is formed in the coupling hole formed in the lower surface of the motor housing, when the coupling bolt is fastened to the coupling hole, there is a problem in that a crack (ack) phenomenon occurs in the coupling hole, and the motor cannot be held in a firm state due to a reduction in fastening force, and durability is remarkably reduced.
Further, since the above-mentioned brackets are provided in at least one, i.e., a plurality of, units, and are respectively coupled to the motor housing, not only is the assembly process somewhat complicated, but also the reinforcement function is not provided between the first bracket and the second bracket, so that it is difficult to stably couple the motor to the dryer body. In addition, in a state where the fixing holes formed in the first bracket and the second bracket are matched with the coupling holes of the motor housing, it is necessary to insert the coupling bolts to assemble the screws, and it is difficult to accurately match the fixing holes and the coupling holes, so that there is a problem in that productivity is low.
In order to solve the above problems, the present inventors have proposed a fixing device for a motor for a washing machine having a novel structure.

Detailed Description
Fig. 1 is a perspective view of a motor 10 for a washing machine according to the present invention as viewed from the front, and fig. 2 is a perspective view of the motor 10 for a washing machine according to the present invention as viewed from the rear. The motor 10 of the present invention is provided inside a body of a washing machine or dryer, not shown, in a state where the motor housing 11 is fastened to the fixing bracket 20, so that the rotary drum of the washing machine or dryer is stably driven by a belt or the like in a state where the motor 10 is supported by the fixing bracket 20. The term "motor for washing machine" is mainly described in the present specification, but is not limited to the motor for washing machine, and although the term is described, the term is also applicable to a motor for a dryer for laundry or other purposes.
As shown in fig. 1 and 2, a motor case 11 and a fixing bracket 20 of a motor 10 for a washing machine according to the present invention are provided so as to be coupled to and uncoupled from each other by a coupling bolt B described later.
The motor housing 11 of the motor 10 of the present invention is formed by insert-injection molding a bulk molding compound type resin mold having a stator 12 and a rotor 13. The cylindrical first fixed support portion 14 is formed to protrude to one side while maintaining a predetermined angle to the front outside of the motor case 11. A driving pulley 15A is coupled to the front of a rotary shaft 15 that penetrates the center of the motor housing 11 and rotates, and rotates together with the rotary shaft 15 to drive a drum (not shown) of the dryer or the washing machine by a belt (not shown).
The fixing bracket 20 includes, in an integrated manner: a circular front frame 22 having a rear bearing cover placement portion 21 formed in the center of the motor housing 11; a reinforcing rib 23 protruding to the rear side of the front frame 22; a cylindrical second fixing support portion 24 is formed at the end of the reinforcing rib 23, and a plurality of cylindrical fixing portions 25 having hollow portions may be formed inside the front frame 22 with a predetermined interval therebetween.
The first cylindrical fixed support portion 14 and the second cylindrical fixed support portion 24 of the fixing bracket 20, which are formed to protrude from the front side of the motor housing 11, may be formed to protrude at a predetermined interval while maintaining the same angle such that the entire weight of the motor housing 11 is directed to the first cylindrical fixed support portion 14 and the second cylindrical fixed support portion 24 of the motor housing 11 and the fixing bracket 20, respectively, thereby preventing the motor housing 11 from being inclined in any one side direction to stably install the motor 10.
The first cylindrical fixing support portion 14 of the motor housing 11 and the second cylindrical fixing support portion 24 of the fixing bracket 20 are illustrated as being provided below in the illustrated drawings, but may be provided above the motor housing 11 and the fixing bracket 20.
Fig. 3 is a perspective view of the motor 10 for a washing machine of the present invention, which is exploded and viewed from the front, and fig. 4 is a perspective view of the motor 10 for a washing machine of the present invention, which is exploded and viewed from the rear.
The rotary shaft 15 of the motor 10 of the present invention is supported so as to be rotatable on the rear side by a rear bearing 16. The rear bearing cover 16A inserted into the rear bearing 16 may be disposed around the inside of the rear bearing cover placement portion 21, and the rear bearing cover placement portion 21 is integrally formed at the center of the front frame 22 of the fixing bracket 20. Preferably, the rear bearing cap 16A is formed integrally with the rear bearing cap-placing portion 21 of the front frame 22 by insert injection molding. In contrast, when the motor 10 is assembled, the assembly process of the rear bearing cover 16A can be omitted, and the assembly process can be shortened, thereby increasing the bonding strength of the rear bearing 16.
The rear surface 11A of the motor case 11 has a coupling portion 110 formed to protrude rearward at a predetermined interval. The cylindrical fixing portion 25 of the fixing bracket 20 is formed to be coupled corresponding to the coupling portion 110, and the motor housing 11 and the fixing bracket 20 can be fastened and coupled by coupling the coupling bolt B to the coupling portion 110 so as to penetrate the fixing portion 25.
Preferably, the coupling portion 110 of the motor housing 11 and the cylindrical fixing portion 25 of the fixing bracket 20 are respectively formed to protrude at positions (symmetrical positions) corresponding to apexes of the regular triangle, thereby stably and balancedly achieving coupling of the motor housing 11 and the fixing bracket 20.
In the coupling portion 110 of the motor case 11, the fitting protrusion 111 is formed to protrude rearward at a predetermined interval on the rear surface 11A of the motor case 11. The nut 112 is provided by insert injection molding inside the insertion protrusion 111, but it is preferable that the rear insertion hole 111A of the insertion protrusion 111 is formed in communication with the assembly screw hole 112A of the nut 112.
In the present invention, it is preferable that the fitting protrusion 111 of the coupling portion 110 of the motor case 11 is designed to be located in the rear inner peripheral direction of the rear surface 11A of the motor case 11. Since the joint is formed at the peripheral portion of the motor housing 11 in the past, the peripheral dimension of the motor housing 11 is increased, but the present invention can minimize the peripheral dimension of the motor housing 11.
A plurality of cylindrical fixing portions 25 integrally formed with a predetermined interval therebetween and protruding are provided in front of the circular front frame 22 constituting the fixing bracket 20. In order to provide the motor 10 to the body of the washing machine or dryer, coupling holes 14', 24' are formed at the center of the cylindrical first and second fixed supports 14, 24, respectively.
Fig. 5 is a sectional view showing a state in which the fixing bracket 20 is disassembled in the motor 10 for the washing machine of the present invention, and fig. 6 is a sectional view showing a state in which the fixing bracket 20 is coupled in the motor 10 for the washing machine of the present invention.
The motor case 11 of the present invention is molded from a resin material in a state in which the stator 12 is placed in an insert injection mold. Preferably, a Bulk Molding Compound (BMC) resin is used as the resin material. Accordingly, the motor housing 11 is formed as one piece by the stator 12 and the resin molding.
The rotation shaft 15 penetrates the center portion of the motor housing 11. Inside the motor housing 15, there is a space into which the rotor 13 can be inserted, and the rotor 13 is coupled to the rotation shaft 15 and rotates together. The motor housing 11 has a plurality of coupling portions 110 formed to protrude rearward on a rear surface thereof.
The coupling portion 110 has an insertion protrusion 111 protruding rearward, and the insertion protrusion 111 is inserted into a cylindrical fixing portion 25 formed in the fixing bracket 20. The cylindrical fixing portion 25 is divided into a front space and a rear space by the stopper portion 251. The front space is the front fitting space portion S1, and the rear space is the rear fitting space portion S2.
The rear bearing 16 is coupled to a rear bearing cover 16A, and the rear bearing cover 16A is injection molded around the inside of the rear bearing cover placement portion 21 by insert molding, and the rear bearing cover placement portion 21 is integrally formed at the center of the circular front frame 22.
When the fitting protrusion 111 is coupled to the front fitting space S1, the rear end of the fitting protrusion 111 is placed in the front fitting space S1 while making surface contact with the front surface of the stopper 251. At the same time, the coupling bolt B penetrates the coupling bolt insertion hole 251A bored in the center of the stopper portion 251 and the rear insertion hole 111A of the insertion protrusion 111 corresponding thereto. The coupling bolt B is screw-coupled with a nut 112 insert-injection-molded inside the insert protrusion 111, thereby coupling the motor housing 11 and the fixing bracket 20.
In the state of double-coupling state in which the insertion protrusion 111 of the coupling portion 110 is coupled with the front insertion space portion S1 of the fixing portion 25 in the state in which the rear bearing cover 16A is inserted into the rear bearing 16, such a coupling structure of the present invention can provide a triple-coupling state in which it is coupled by the coupling bolt B, thereby achieving a more firm and stable coupling.
In particular, the fastening force can be further improved by screwing the coupling bolt B to the nut 112 insert-molded inside the insertion protrusion 111, preventing damage or breakage of the coupling hole for screw assembly of the motor housing 11, and furthermore, since the insertion protrusion 111 of the coupling portion 110 constituting the motor housing 11 is fastened by the coupling bolt B in a state where the front insertion space portion S1 of the cylindrical fixing portion 25 is inserted, operability is improved, and the assembly time is shortened. In addition, vibration or noise can be prevented from occurring when the motor is operated by the firm coupling.
Fig. 7 is a perspective view showing still another embodiment of deforming the coupling portion 110 of the motor housing 11 and the cylindrical fixing portion 25 of the fixing bracket 20 of the present invention, and fig. 8 is a cross-sectional view showing another embodiment of deforming the coupling portion 110 of the motor housing 10 and the cylindrical fixing portion 25 of the fixing bracket 20 of the present invention.
As shown in fig. 7, the insertion guide blades 111-1 are formed to protrude from both ends of the insertion protrusion 111 of the coupling portion 110 constituting the motor housing, and the insertion guide grooves 25-1 are formed to both ends of the front of the cylindrical fixing portion 25 of the fixing bracket 20, and the insertion guide blades 111-1 at both ends of the insertion protrusion 111 can be guided and coupled along the insertion guide grooves 25-1, so that easy coupling can be achieved.
Also, in the above-described other embodiment, since the insertion protrusion 111 maintains the state of the insertion engagement in the insertion space portion S1 in front of the cylindrical fixing portion 25 in a state where the insertion guide blades 111-1 at both ends of the insertion protrusion 111 are inserted into the insertion guide grooves 25-1, even if the coupling bolts B are loosened or damaged by external impact or the like, the fastening force can be maintained, thereby more firmly maintaining the coupling of the motor housing 11 and the fixing bracket 20 while preventing twisting to achieve more stable coupling.
Referring to fig. 8, the first magnet N1 having the bolt insertion hole N1 'is insert-molded in the insert protrusion 111 of the coupling portion 110 constituting the motor housing, and the second magnet N2 having the bolt insertion hole N2' is insert-molded around the inner side of the cylindrical fixing portion 25 in front of the stopper portion 251 of the cylindrical fixing portion 25 of the fixing bracket 20, after the nut 112 is insert-molded, and the insert protrusion 111 of the coupling portion 110 constituting the motor housing is easily insert-fitted in the front insert space S1 of the cylindrical fixing portion 25, whereby the first magnet N1 and the second magnet N2 are respectively provided in any one of the insert protrusion 111 and the cylindrical fixing portion 25, and the motor housing 11 and the fixing bracket 20 are coupled to each other by being precisely aligned with each other.
It should be noted that the above description of the present invention is merely illustrative for better understanding of the present invention and is not intended to limit the scope of the present invention.
