- the user uses the sub-laundry of each of the twin washing machines individually but as a whole product as a single product.
- any one sub washing machine does not operate smoothly, it is considered that the problem of the whole product is not a part of the product. For example, if there is an abnormality in the second washing unit, the user may determine that there is an abnormality in the entire twin washing machine. Since the twin washing machine is supplied by one supplier rather than the first laundry unit and the second laundry unit, it is very important to provide reliability to the user.

- the air inlet 341 may include an opening 343.
- the opening may be provided in the rotor frame 320.
- the opening 343 may be formed perpendicular to the bottom wall 340 of the rotor. Therefore, the outside air does not flow in the stator direction (vertical top direction in FIG. 10) from the outside of the rotor, but flows in the circumferential direction from the outside of the rotor. That is, outside air is introduced into the rotor in a direction parallel to the rotation axis direction or the rotation direction of the rotor, not the direction perpendicular to the rotation axis direction of the rotor. Therefore, the inflow direction of the outside air is not distorted or refracted, so that the outside air can be smoothly introduced into the rotor.
- the air inlet 341 includes a plurality of sidewalls. These sidewalls may be integrally formed with the bottom wall 340 of the rotor frame 320.
- the bottom wall 340 may have a cutout 349 extending in a radial direction.
- the rotor frame 320 may be formed by integrally forming the side wall 330, the bottom wall 340, and the hub 350 and pressing a material such as an iron plate.
- the protrusion 342 may be formed while pushing the bottom wall 340 near the cutout 349 upward, and an opening 343 may be formed. Therefore, the area of the opening 343 may be a value obtained by multiplying the length of the cutout 349 by the protrusion height.
- the protrusion 342 may protrude from the bottom wall 340 in the direction of a predetermined height stator.
- the protrusion 342 may be referred to as a recess in view of inverting the rotor frame 320.
- the protrusions or depressions are formed through a plurality of side walls and thus form a predetermined space.
- the protrusion may be referred to as a channel through which outside air is continuously introduced to guide the flow of air into the rotor frame through the opening 342. Since the outside air flows into the rotor through the channel, it may be referred to as an outside air inflow channel 342 in order to distinguish the channel from a channel to be described later.

Like the inner side wall and the outer side wall, the front side wall is formed to extend substantially in the vertical direction (stator direction) on the bottom wall 340 and connect the inner side wall and the outer side wall.
- the front wall may be named according to the rotation direction of the rotor.
- a rear side wall may be formed to face the front side wall, and an opening 343 may be formed in the rear side wall.
- the protruding portion or the recessed portion is formed in a space shape in which the upper side, the left and right sides, and the front side are blocked, and an opening is formed in the rear side.
- the lower side of the protrusion or depression is open. That is, the lower side of the outdoor air inflow channel is open.
- the volume of the outside air inflow channel may be roughly determined as follows.
- the inner wall and the outer wall may be assumed to be straight lines having the same length.
- the cutout 349 and the front wall are straight lines having the same length.
- the volume may be a value obtained by multiplying the length of the inner wall (or the outer wall), the length of the cutout (or the front wall), and the protrusion heights of the protrusions.
- a space corresponding to the volume of the protrusion is formed at the outer side of the rotor frame 220, specifically, the bottom wall 340 of the rotor frame, and this space may be referred to as a space in direct communication with the opening 343.
- the opening 343 may be a configuration in which air flows out of one outside air inlet channel 342.
- the openings 343 defined by the bottom wall 340, the outer wall 345, the inner wall 346, and the upper wall 348 allow air guided by these walls to pass through the rotor 343. It can be smoothly introduced into the frame 320.
- the flow direction of the air is rapidly changed in the vicinity of the opening 343, and the generation of vortices is remarkably reduced, thereby significantly increasing the flow rate and flow rate of the air flowing through the opening 343.
- Increasing the flow rate and flow rate of air means increasing the cooling efficiency of the stator.
- the outside air inflow channel 342 may be formed to protrude or be recessed from the bottom wall and have at least three sides and extend in the circumferential direction to be connected to the opening 343.
- the channel is a space in which outside air is collected and may be referred to as a guide space that guides the outside air to the opening 343.
- the hub 350 formed at the center of the bottom wall 340 of the rotor frame 320 is a portion to which the connector is coupled. Therefore, it includes a horizontal surface 351 protruding from the bottom wall 340 so that the connector can be firmly coupled.
- an outer side surface 353 and an inner side surface 352 are formed at the radially outer side and the inner side of the horizontal plane 351.
- the inner surface of the hub is preferably formed in a substantially vertical plane. And the inner surface is preferably formed to have a predetermined radius. This is because the drum shaft is inserted through the inner surface.
- outer surface of the hub may be formed to have an inclined surface.
- the inclined surface may be formed to be inclined upward toward the center.
- the horizontal surface, the inner surface and the outer surface of the hub may be referred to as a structure formed to be joined to the connector.
- the connector formed to mate with these surfaces is coupled to the rotor frame 320 from the bottom of the rotor frame 320 shown in FIG.
- the connector and the hub can be firmly fixed in the radial direction.
- the coupling force in the axial direction and the circumferential direction may be secured through additional fastening means such as bolts and the like.
- the horizontal surface of the hub may be part of the bottom wall of the rotor frame. That is, it may have the same plane as the bottom wall.
- the embossing part 44 may be omitted in FIG. 10. That is, it can be seen that the stiffness of the bottom wall 340 can be reinforced through the outside air inlet channel itself forming the air inlet 341. Therefore, on the premise that the rotors shown in FIG. 1 and the rotors shown in FIG. 10 have the same size, it can be seen that twice as many air inlets 341 can be formed through the present embodiment. That is, it can be seen that the number can be further increased even if the radial lengths of the openings 343 through which air is introduced into the rotor are the same.
- opening 343 may abut sidewall 330.
- the space where the side wall can be bent and the space where the outer wall 345 can be bent may be lost or become very narrow. Therefore, it is preferable that a certain radial clearance length is formed between the side wall 330 and the outer wall 345.
- opening 343 may abut hub 350.
- the space where the inner wall 346 can be bent and the space where the hub 350 can be bent may be eliminated or become very narrow. Therefore, it is preferable that a certain radial clearance length is formed between the hub 350 and the inner wall 346.
- the relationship between the area of the opening, the flow rate, and the flow rate of the air can be examined.
- the area of the opening increases as the radial length of the opening increases.
- a continuous bottom wall 340 is provided on the radially outer side and the inner side with respect to the opening 343. That is, it is not desirable to further extend the opening from the radial position of the stator coil to the radially outer side or further extend the opening to the radially inner side.
- an increase in volume of the outside air inlet channel near the openings 343 has more effective cooling performance. This is because the more densely formed the openings through which air flows in the circumferential direction, the more the continuous flow of air is disturbed in the circumferential direction.
- FIG. 11 may be an embodiment in which the length or volume of the channel 342 is further increased in the circumferential direction in the embodiment illustrated in FIG. 10.

- the air inlet portion 341 may be formed in a fan shape.
- the circumferential distance between the air inlet 341 and the air inlet 341 may be greater than the circumferential length of the air inlet ().
- the sizes of the two become different. That is, as the circumferential length of the channel 342 is increased, the circumferential distance between the air inlet portion 341 and the air inlet portion 341 becomes smaller than the circumferential length of the air inlet portion 341.
- the air introduced through any one of the air inlet portion 341 may immediately hit the front side wall 347 of the adjacent air inlet portion 341.
- the front wall 347 and the upper wall 348 may be acute rather than perpendicular to each other.
- the front wall 347 and the upper wall 348 may be connected to each other in a curved surface, all of them may form a curved wall. In this case, as the angles or shapes of the rear wall and the upper wall are changed, the shapes of the outer wall 345 and the inner wall 346 will also vary.
- the plurality of air inlet portions along the radial direction may be formed in a form that leads to each other.
- it may be formed as one inclined wall or curved wall of the rear side wall and the upper side wall 348 of the air inlet portion (341). Therefore, the air flowing from one of the air inlets 341 may flow while rising along the circumferential direction on the inclined wall or curved wall of the adjacent air inlet. Therefore, the structural features of the protrusion 342 can cause a smooth air flow and rise of air.
- the circumferential length of the outer wall 346 should be longer than the circumferential length of the inner wall 346.

That is, as the rotor frame 320 rotates, air around the outer bottom surface of the rotor frame collects in the external air supply channel 360. In particular, the air flows radially outwardly around the central portion of the rotor frame and collects in the external air supply channel 360.

That is, since a portion of the bottom wall 340 is formed to protrude in the stator direction, the outside of the bottom wall may be formed in an annular shape in a recessed shape. In other words, when viewed from the inside of the rotor frame 320, the outside air supply channel 360 is formed to protrude in an annular shape, and when viewed from the outside of the rotor frame 320, the outside air supply channel 360 may be formed in an annular recessed shape.

- the outer wall 361 may be formed to communicate with the outside air supply channel 360 along the circumferential direction. That is, some sections of the outer wall 361 are blocked and some sections are open. Therefore, the air inside the outside air supply channel 360 may flow outside the outside air supply channel through an open section of the outer wall 361.
- the closed section and the open section of the outer wall 361 may be formed to alternate in the circumferential direction.

- the upper wall 362 may be a horizontal wall on which the bottom wall 340 protrudes upward.
- a portion of the upper wall 362 may be formed to protrude outward from the rotor frame (the direction opposite to the stator direction). That is, a portion of the horizontal upper wall 362 may protrude downward. This may act as a blade 362a to promote outside air flow in the outside air supply channel 360.
- the outer wall 361 may be formed to be bent along the circumferential direction.
- the outside air supply channel 360 has a relatively narrow region 381, narrow region between the inner wall 363 and the outer wall 361, and a width between the inner wall 363 and the outer wall 361, H.

That is, one end of the arc-shaped wall portion of the narrow zone 381 may be formed on the outer side or the inner side in the radial direction compared to the other end. It is preferable that the front side is formed radially outward rather than the rear side with respect to the rotation direction of the rotor. In this case, the radial length of the front wall portion of the radial wall portion 361c becomes larger than the radial length of the rear wall portion. Therefore, the outside air supply channel 360 may be formed like a pinwheel shape.
