Description

BACKGROUND

1. Field

The present disclosure relates to a pump motor having improved safety and a washing machine having the same.

2. Description of Related Art

In general, household appliances using water, such as washing machines, dishwashers, and the like, can discharge the used water to the outside of the household appliances through a pump motor.

As an example of the household appliances using water, a washing machine is an apparatus for removing foreign matters from laundry by the friction between washing water and the laundry, and may include a water drainage device for discharging the used washing water to the outside from the water tank for receiving the washing water. When the washing of the laundry is finished, the washing water contaminated during the washing process is discharged to the outside through the water drainage device. Discharge of the contaminated washing water may be achieved by driving a pump motor of the water drainage device.

Since such a pump motor is provided inside the household appliance using water, moisture may be introduced into the pump motor during the operation of the household appliance. In the case where moisture is introduced into a terminal part that supplies power to the pump motor, a plurality of terminals may be electrically connected to each other by moisture so that short-circuiting or tracking phenomenon may occur. Accordingly, there is the risk of fire.

FIG. 1 is a perspective view schematically illustrating a washing machine 1 including a pump motor 10 according to an embodiment of the present disclosure.

The washing machine 1 may include a main body 20 that forms an outer appearance thereof and is provided with an opening on the front surface thereof and a door 30 to open and close the opening. The main body 20 may include a water tub 21 for storing washing water and a rotary tub 22 that is rotatably disposed inside the water tub 21 and accommodates laundry.

A drainage device 40 for discharging the washing water stored in the water tub 21 to the outside may be provided below the water tub 21.

The drainage device 40 may include a pump 41 including a drainage filter 44, a first drainage pipe 42 connecting the water tub 21 and the pump 41, and a second drainage pipe 43 to discharge the washing water passed through the pump 41 to the outside of the washing machine 1. An impeller (not illustrated) of the pump motor 10 may be disposed inside the pump 41, and the washing water may be discharged to the outside of the washing machine 1 through the first and second drainage pipes 42 and 43 by rotation of the impeller.

FIG. 2 is a perspective view specifically illustrating the pump motor 10 illustrated in FIG. 1, and FIG. 3 is an exploded perspective view illustrating the pump motor 10 illustrated in FIG. 2.

Referring to FIG. 2, the pump motor 10 may include a case 100 forming an outer appearance thereof and a cover part 200 detachably coupled to the case 100. A motor (not illustrated) including a stator (not illustrated) and a rotor (not illustrated) may be provided inside of the case 100. The impeller connected to a rotary shaft (not illustrated) may rotate as the rotary shaft connected to the rotor rotates.

Referring to FIG. 3, a socket part 110 including a terminal part 120 therein may be disposed in a portion of the case 100.

The terminal part 120 may be supplied with power from a power source (not illustrated) provided in the washing machine 1. The terminal part 120 may include a pair of a first terminal 120a and a second terminal 120b protruding from the case toward the front (for example, a direction in which the cover part 200 is disposed) for connection with an electric wire (not illustrated). Thus, the pump motor 10 may be operated by receiving electricity from the power supply.

The first and second terminals 120a and 120b may be AC terminals or DC terminals. In addition, each of the first and second terminals 120a and 120b may have a rectangular plate-like structure or a cylindrical shape arranged long in the longitudinal direction. For convenience of explanation, the terminal part 120 in the embodiment of the present disclosure is described to provide with a pair of first and second terminals 120a and 120b, but the terminal part 120 is not limited thereto. The terminal part 120 may include three or more terminals.

The socket part 110 may include the terminal part 120 described above in the inside thereof and may surround the terminal part 120. In addition, the socket part 110 may include an opening 115 opened toward the front so that the terminal part 120 is connected to the electric wire.

Further, the pump motor 10 may include the cover part 200 that can prevent moisture from flowing into the socket part 110 having the terminal part 120 from the outside. The cover part 200 is configured to cover a portion of the case 100 including the socket part 110 and may include a rear cover 220 detachably coupled to the case 100 and a front cover 210, one end of which is pivotally coupled to the rear cover 220.

Referring to FIG. 3, the rear cover 220 may have a pair of coupling grooves 221 and 222 at opposite side ends thereof, and a pair of coupling projections 101 and 102 may be provided on opposite sides of the case 100 corresponding to this. Accordingly, the pair of coupling grooves 221 and 222 of the rear cover 220 may be snap-engaged with the coupling projections 101 and 102 of the case 100, respectively, through which the rear cover 220 and the front cover 210 coupled thereto may be detachably coupled to the case 100.

The front cover 210 may be pivoted between a first position (see FIG. 7) for closing the socket part 110 and a second position (see FIG. 9) for opening the socket part 110. Therefore, when connecting the electric wire to the terminal part 120 or maintaining the terminal part 120, the socket part 110 is opened by rotating the front cover 210 to the second position, and normally the socket part 110 may be closed by rotating the front cover 210 to the first position. Thus, it is possible to prevent moisture from flowing into the socket part 110 due to vibration or the like that may occur during operation of the washing machine 1.

Further, the socket part 110 may include a moisture blocking member 112 that blocks a gap between the case 100 and the cover part 200 to prevent the inflow of moisture, at least one barrier 113 capable of preventing movement of moisture between the first and second terminals 120a and 120b, and at least one drain hole 114 that discharges the moisture introduced into the socket part 110 to the outside.

FIG. 4 is an enlarged perspective view illustrating a socket part 110 of the pump motor 10 illustrated in FIG. 3. FIG. 5 is a front view of the socket part 110 illustrated in FIG. 4, and FIG. 6 is a right side view of the socket part 110 illustrated in FIG. 4.

Hereinafter, the structure of the socket part 110 having the terminal part 120 thereinside will be described in detail with reference to FIGS. 4 to 6.

Before the structure of the socket part 110 and its effect are explained, a path through which moisture flows into the pump motor 10 in the operation process of the washing machine 1 is as follows.

In the operation process of the washing machine 1, a large amount of washing water is used for washing laundry, so that periphery of the washing machine 1 may be generally distributed with high moisture. Since the washing machine 1 generates a lot of vibration in the operation process, the washing water or the moisture in the periphery of the washing machine 1 may flow into the pump motor 10. The moisture flowing into the pump motor 10 is condensed and flows down along the surface of the pump motor 10 due to the vibration of the washing machine 1 or gravity so that the moisture may flow into the socket part 110 through a gap between the case 100 and the cover part 200 around the socket part 110. As a result, a tracking phenomenon may occur between the first and second terminals 120a and 120b inside the socket part 110.

Referring to FIG. 4, the socket part 110 in this embodiment may be provided with the moisture blocking member 112 to prevent the above-described tracking phenomenon.

As described above, the first and second terminals 120a and 120b may be disposed in the inside of the socket part 110 and an opening 115 opened toward the front may be provided to connect the first and second terminals 120a and 120b to the electric wire (or plug). In this case, the moisture flowing into the socket part 110 may be primarily blocked by the cover part 200 surrounding the socket part 110. Further, the moisture blocking member 112 may secondarily block the moisture flowing in through the gap between the cover part 200 and the case 100.

Hereinafter, the structure and function of the socket part 110 including the moisture blocking member 112 will be described in detail. The socket part 110 may include a body part 111 surrounding the first and second terminals 120a and 120b and the moisture blocking member 112 formed along an edge of the body part 111.

The body part 111 may have a shape in which a peripheral portion of the case 100 where the terminal part 120 is disposed protrudes toward the front and may have a shape corresponding to a plug or an outlet connected to the electric wire to be coupled. Accordingly, the body part 111 may be in the form of a wall surrounding the terminal part 120, and the terminal part 120 may be disposed inside the body part 111. Since the body part 111 surrounds the periphery of the terminal part 120, moisture that flows into the terminal part 120 directly from the upper, lower, left, and right sides of the terminal part 120 may be blocked.

The moisture blocking member 112 may protrude outward of the socket part 110 along the edge of the body part 111, and may be bent from the edge of the body part 111 toward the outside of the socket part 110. For example, the moisture blocking member 112 may be in the shape of a flange or rib formed along the edge of the body part 111 toward the outside of the socket part 110.

The moisture blocking member 112 may block the inflow path of moisture that can move to the inside of the socket part 110 along the outer surface of the body part 111. For example, even when the moisture distributed on the outer surface of the body part 111 moves toward the terminal part 120 along the outer surface of the body part 111, the moisture blocking member 112 protruding from the body part 111 may block the moisture which is intended to move toward the inside of the socket part 110 along the outer surface of the body part 111. In addition, the moisture moving along the outer surface of the body part 111 may be removed by flowing down to the lower side of the socket part 110 along the rear surface of the moisture blocking member 112.

Specifically, the moisture blocking member 112 may include an upper member 112a, a right member 112b, a lower member 112c, and a left member 112d, depending on the position disposed on the body part 111. The upper member 112a, the right member 112b, the lower member 112c, and the left member 112d may be integrally formed.

Since the moisture that can flow into the socket part 110 may move from the upper portion to the lower portion of the socket part 110 by gravity, a large amount of moisture may be distributed on the top surface 111a of the body part 111, on which the moisture is less likely to move by gravity, as compared with the bottom surface and opposite side surfaces. Even when the moisture moves toward the opening 115 of the socket part 110 along the top surface 111a of the body part 111, the movement path of the moisture may be blocked by the upper member 112a bent from the top surface 111a of the body part 111 and the moisture that is blocked from moving may fall down below the socket part 110 through the rear surface 112a″ of the upper member 112a, the rear surfaces of the right or left members 112b and 112d and the rear surface of the lower member 112c.

Further, referring to FIG. 6, the upper member 112a of the moisture blocking member 112 may be disposed in a state where the upper member 112a is advanced toward the front than the right member 112b, the lower member 112c, and the left member 112d. Therefore, an inclined surface 116 may be formed between the upper member 112a and the right and left members 112b and 112d, respectively. Thus, the moisture distributed on the top surface 111a of the body part 111 may be removed by easily flowing down along the inclined surface 116 to the lower side of the socket part 110.

In addition, the angle α between the upper member 112a of the moisture blocking member 112 and the top surface 111a of the body part 111 may be a right angle. By changing the angle α, the moisture that can be distributed on the upper member 112a may be easily moved to the lower side of the socket part 110. Also, the top surface 111a of the body part 111 may be inclined so that the inclination of the top surface 111a of the body part 111 decreases toward the rear where the case 100 is coupled from the front where the moisture blocking member 112 is connected. Thus, the moisture that can flow into the terminal part 120 through the body part 111 may be blocked by moving the moisture distributed on the top surface 111a of the body part 111 toward the outer surface of the case 100 which is opposite to the opening 115 of the socket part 110 along the inclined top surface 111a.

Further, the socket part 110 in this embodiment may include at least one barrier 113 to prevent the above-described tracking phenomenon.

The barrier 113 may be disposed between the first terminal 120a and the second terminal 120b. The barrier 113 may partition between the first terminal 120a and the second terminal 120b by isolating them. Therefore, even when moisture flows into the socket part 110 in which the first terminal 120a and the second terminal 120b are disposed, the barrier 113 may block the movement path of the moisture between the first terminal 120a and the second terminal 120b, thereby preventing the tracking.

Further, the barrier 113 may include a first barrier 113a and a second barrier 113b as illustrated in FIGS. 4 and 5. Thus, the first terminal 120a and the second terminal 120b may be double isolated from each other by them.

Specifically, referring to FIG. 5, the inside of the socket part 110 may be divided into a first space S1 in which the first terminal 120a is disposed and a second space S2 in which the second terminal 120b is disposed by the first and second barriers 113a and 113b provided between the first terminal 120a and the second terminal 120b. Since the first space S1 and the second space S2 are isolated from each other by the first and second barriers 113a and 113b, the movement of moisture between the first space S1 and the second space S2 may be blocked.

For example, even when the moisture introduced into the first space S1 in which the first terminal 120a is disposed is moved toward the second space S2 in which the second terminal 120b is disposed by vibration, the flow of the moisture may be primarily blocked by the first barrier 113a. Even if the moisture passes over the first barrier 113a, the second barrier 113b may shut off the inflow path secondarily. Alternatively, the barrier 113 may be composed of three or more.

Also, the socket part 110 in this embodiment may include at least one drain hole 114 to prevent the above-described tracking phenomenon.

The drain hole 114 may be formed in the lower portion of the socket part 110. The drain hole 114 may be formed in the lower portion of the body part 111 or may be formed between the body part 111 and the moisture blocking member 112. Specifically, the drain hole 114 may be formed in the lower surface of the body part 111 close to the lower member 112c of the moisture blocking member 112. Accordingly, the drain hole 114 may discharge moisture, which may be accumulated inside the socket part 110 provided with the terminal part 120, to the outside of the socket part 110.

The drain hole 114 may include a plurality of drain holes, and may be formed in opposite sides of the barrier 113 disposed inside the socket part 110, respectively. For example, as illustrated in FIG. 5, a first drain hole 114a is formed in a lower portion of the body part 111 on the first space S1 and a second drain hole 114b is formed in a lower portion of the body part 111 on the second space S2. Thus, even if moisture flows into the first and second spaces S1 and S2 in which the first and second terminals 120a and 120b are disposed, respectively, the moisture may be discharged by the first and second drain holes 114a and 114b. Thus, the movement of moisture between the first terminal 120a and the second terminal 120b may be blocked in advance.

In addition, the inner lower portion of the socket part 110 including the drain hole 114 may include an inclined surface inclined toward the drain hole 114. Thus, even when moisture flows into the socket part 110, the inflowing moisture moves toward the drain hole 114 along the inclined surface, so that the moisture may be easily discharged through the drain hole 114. In addition, since the lower portion of the body part 111 on the first space S1 includes an inclined surface inclined toward the first drain hole 114a and the lower portion of the body part 111 on the second space S2 includes an inclined surface inclined toward the second drain hole 114b, the moisture introduced into the first and second spaces S1 and S2 may be easily discharged through the first and second drain holes 114a and 114b, respectively.

FIG. 7 is a perspective view illustrating a state in which the cover part 200 of the pump motor 10 illustrated in FIG. 2 is closed, and FIG. 8 is a cross-sectional view illustrating the pump motor 10 taken along a line I-I in FIG. 7. FIG. 9 is a perspective view illustrating a state in which the cover part 200 of the pump motor 10 illustrated in FIG. 2 is opened, and FIG. 10 is a cross-sectional view illustrating the pump motor 10 taken along a line II-II in FIG. 9.

Hereinafter, the blocking of the inflow of moisture into the socket part 110 due to the opening and closing of the cover part 200 will be described with reference to FIGS. 7 to 10.

The cover part 200 may include the front cover 210 and the rear cover 220 as described above. The rear cover 220 may be detachably coupled to a portion of the case 100 including the socket part 110 and the front cover 210 may be connected to the rear cover 220 to be openable and closable.

The front cover 210 may include a front surface 212, a top surface 211 bent from the front surface 212, and a right surface 213 and a left surface 214 bent from the front surface 212. When the front cover 210 is closed, the inner space formed by the top surface 211, the front surface 212, the right surface 213, and the left surface 214 may accommodate the socket part 110. The top surface 211 of the front cover 210 may be rotatably connected to the rear cover 220, and the front cover 210 may be opened and closed by rotation.

As illustrated in FIGS. 7 and 8, when the front cover 210 is closed, the socket part 110 may be received in the inner space formed by the top surface 211, the front surface 212, the right surface 213, and left surface 214 of the front cover 210, whereby the socket part 110 may be closed. Accordingly, the moisture distributed outside the cover part 200 may be prevented from flowing into the socket part 110 provided with the terminal part 120.

The front cover 210 may be rotated with respect to the rear cover 220 for opening and closing the front cover 210. To this end, the top surface 211 of the front cover 210 may be rotatably connected to the rear cover 220. In addition, one end 211a of the top surface 211 of the front cover 210 and one end 220a of the rear cover 220 to which the top surface 211 of the front cover 210 is connected may be spaced apart by a predetermined gap from each other in order to secure a space in which the top surface 211 of the front cover 210 can rotate, and a predetermined gap may be formed between the cover part 200 and the case 100 including the socket part 110.

As illustrated in FIG. 8, when the front cover 210 is closed, the moisture blocking member 112 interferes with the top surface 211 of the front cover 210, thereby shielding the gap that may be formed between the front cover 210 and the case 100. Therefore, the moisture that flows into the first gap G1 formed between the one end 211a of the top surface 211 and the one end 220a of the rear cover 220 may be prevented from flowing into the socket part 110 through the gap between the cover part 200 and the case 100.

As described above, when the front cover 210 is closed, the moisture blocking member 112 may block the moisture that flows into the socket part 110 through the first gap G1 between the front cover 210 and the rear cover 220 and the gap between the cover part 200 and the case 100, thereby easily preventing the tracking phenomenon.

As illustrated in FIGS. 9 and 10, when the front cover 210 is opened, the socket part 110 may be opened toward the front, and the electric wire may be easily connected to the terminal part 120 through the opening.

When the front cover 210 is opened from a closed state, the moisture distributed on the outer surface of the front cover 210 may move to the lower side of the front cover 210 along the top surface 211 of the front cover 210 by gravity.

As illustrated in FIG. 10, when the front cover 210 is opened, the rear surface 112a″ of the upper member 112a of the moisture blocking member 112 may interfere with a part of the top surface 211 of the front cover 210. Thus, the top surface 211 of the front cover 210 may shield the rear surface of the moisture blocking member 112, and the moisture blocking member 112 may shield the gap formed between the front cover 210 and the case 100.

Accordingly, even when the moisture moving downward along the top surface 211 of the front cover 210 flows into the second gap G2 formed between the one end 211a of the top surface 211 of the front cover 210 and the one end 220a of the rear cover 220, the inflowing moisture may be prevented from flowing into the socket part 110 through the gap between the cover part 200 and the case 100.

As described above, when the front cover 210 is opened, the moisture blocking member 112 may block the moisture from flowing into the socket part 110 through the second gap G2 between the front cover 210 and the rear cover 220 and the gap between the cover part 200 and the case 100, thereby easily preventing the tracking phenomenon.

As described above, the pump motor 10 according to an embodiment of the present disclosure and the washing machine 1 having the same may primarily block the moisture that flows into the socket part 110 provided with the terminal part 120 through the cover part 200 detachably coupled to the case 100 of the pump motor 10.

In addition, the moisture that flows into the socket part 110 may be secondarily blocked by shielding the gap formed between the front cover 210 and the rear cover 220 and the gap formed between the cover part 200 and the case 100 including the socket part 110 for opening and closing the front cover 210 constituting the cover part 200 through the moisture blocking member 112.

Further, even if moisture flows into the inside of the socket part 110 provided with the terminal part 120, the inflowing moisture may be easily discharged through the drain hole 114 provided in the lower portion of the socket part 110, and even if some moisture that has not been discharged remains inside the socket part 110, the barrier 113 provided with between the first terminal 120a and the second terminal 120b may block the movement of the moisture from the first terminal 120a to the second terminal 120b or from the second terminal 120b to the first terminal 120a. Accordingly, the tracking phenomenon, which may be caused by the inflow of the moisture into the first terminal 120a and the second terminal 120b, may be effectively prevented, and the fire due to the tracking may be prevented, so that the stability of the pump motor 10 and the washing machine 1 having the same may be increased.

In the embodiment of the present disclosure, the washing machine 1 provided with the pump motor 10 has been described as an example of household appliances. However, the pump motor 10 according to an embodiment of the present disclosure may be applied to various household appliances having a pump such as a dishwasher, a water purifier, or the like.

In the above description, although various embodiments of the present disclosure are described individually, the respective embodiment is not necessarily solely implemented, the configuration and operation of the respective embodiments may also be implemented in combination with at least one of other embodiments.

In the above description, although the exemplary embodiments of the present disclosure have been shown and described, it should be understood that the present disclosure is not limited to the disclosed embodiments and may be variously modified without departing from the spirit and the scope of the present disclosure. Therefore, the modifications should not be understood separately from the technical spirit or scope of the present disclosure.
