The washing machine motor is controlled via the inverter circuit, and the washing operation including the washing (rinsing) process and the dehydrating process is executed. Furthermore, the hot air supply device is controlled to execute the drying process.

  Now, the arrangement of the lead wires 31 in this embodiment will be described with reference to FIGS. As shown in FIG. 2, the lead wire 31 is drawn out from a lead wire lead-out portion 32 provided at the bottom portion of the water tub 6 on the outer periphery of the drive mechanism portion 17 and hangs downward, and then forms a U shape. It extends upward and is arranged so as to extend upward after being held by the outer box side fixing portion 33 provided on the inner wall surface of the outer box 2.

  At this time, as shown in FIG. 3, the outer box side fixing portion 33 is located in the vicinity of one corner C portion of the outer box 2, in this case, the left rear corner C, of the back plate of the outer box 2. As shown in FIG. 2, it is provided at a height slightly above the bottom of the water tank 6. The outer box side fixing portion 33 holds the lead wire 31 so as to extend in the vertical direction along the back plate of the outer box 2.

  Specifically, as shown in FIG. 4, a mounting portion 34 having two right and left screw holes is provided on the inner surface of the back plate of the outer box 2. In a state where the lead wire 31 extends vertically on the front surface of the mounting portion 34, the intermediate portion is pressed from the front by a holding bracket 35 having a semicircular shape, and the left and right ends of the holding bracket 35 are screwed 36. The lead wire 31 is held by being fixed to the attachment portion 34 by the above.

  And, as shown in FIG. 3, the position of the lead wire lead-out portion 32 is relative to the first imaginary line L1 that connects the water tank center O of the water tank 6 and the one corner C with a straight line when viewed from above. The water tank center O is arranged at an angle range of 15 ° on both sides of the water tank center O (shown with hatching for convenience in FIG. 3). Further, at this time, when viewed from the top surface of the outer box 2, the second imaginary line L <b> 2 that linearly connects the lead wire lead-out part 32 and the outer box side fixing part 33 includes the outer box 2 having the outer box side fixing part 33. The angle θ1 formed with respect to the extending direction (left and right direction) of one side (back plate) is 30 ° to 60 °, in this case, about 60 °.

  In this state, as shown in FIG. 2, the lowermost point of the lead wire 31 and the outer box than the distance A in the height direction between the lowermost point of the lead wire 31 and the lead wire lead-out portion 32. The distance B in the height direction from the side fixing portion 33 is configured to be larger. Moreover, the position of the outer box side fixing | fixed part 33 is located below rather than the lower end of the said hanging rod 7a. In this case, the lead wire 31 has a slack in the vertical direction between the lead wire lead-out portion 32 and the outer box side fixing portion 33, and there is no bent portion in the horizontal direction. As seen from the top, it is almost straight.

  Although not shown, even when the rated load is accommodated in the water tank 6 and the water tank 6 is lowered to the lowest position, the lead wire 31 is held in a state of hanging downward. Further, at this time, the state in which the lead wire 31 has no bent portion in the horizontal direction means that the lead wire 31 immediately after the lead wire lead-out portion 32 is drawn with respect to the direction from the lead wire lead-out portion 32 toward the outer box side fixing portion 33. The direction in which is extended is a state in which the angle is within 45 ° when viewed in the horizontal direction (viewed from above).

  Further, in the present embodiment, the binding portion 37 is provided in at least one location of the lead wire 31 excluding the lowest point between the lead wire lead-out portion 32 and the outer box side fixing portion 33. In this embodiment, for example, the binding portions 37 are provided at three positions. These bundling portions 37 are provided by being bound with a band, a tape, or the like in a state in which energization wires and signal wires constituting the lead wire 31 are bundled.

  Next, the operation and effect of the above configuration will be described. In the above configuration, the drive mechanism portion 17 is displaced up and down according to the load (the amount of laundry and washing water) in the water tank 6 and vibrates in the vertical and horizontal directions together with the water tank 6 during the washing operation. The lead wire 31 may be subjected to stress such as tension or bending. However, in the present embodiment, the portion of the lead wire 31 between the lead wire lead-out portion 32 and the outer box side fixing portion 33 is bent (loosely hangs down), so that the lead wire 31 is not bent. It is possible to suppress stress such as tension or bending that acts.

  If the bent portion of the lead wire 31 comes into contact with (or hits) another portion such as the outer box 2 or the water tank 6, the lead wire 31 may be rubbed and damaged or abnormal noise may be generated. Conceivable. Here, if the lead wire lead-out portion 32 of the drive mechanism portion 17 is located near the center of the side as viewed from the upper surface of the outer box 2, the lead wire 31 is connected to the water tank 6 and the outer box 2. It will pass through the narrow part sandwiched and it will be easy to contact them.

  On the other hand, in the present embodiment, the lead wire lead-out portion 32 of the drive mechanism portion 17 connects the water tank center O of the water tank 6 and one corner C of the outer box 2 with a straight line when viewed from above. With respect to the line L0, it is arrange | positioned in the angle range of 15 degrees on both sides centering on the water tank center O, respectively. Thereby, the lead wire 31 can be arrange | positioned in the comparatively wide space of the corner C vicinity of the outer case 2, and it can prevent effectively contacting the water tank 6 and the outer case 2. FIG.

  Furthermore, it is not preferable that the outer box side fixing portion 33 is located closer to the center of the side when viewed from the upper surface of the outer box 2 because the lead wire 31 is disposed in a narrow space. In the present embodiment, with respect to the position of the lead wire lead-out portion 32 described above, the outer box side fixing portion 33 provided on one side of the outer box 2 is also about 60 ° with respect to the direction in which the second imaginary line L2 extends. The angle θ1 is provided. Thereby, the lead wire 31 can be arrange | positioned in the wide space of the corner C part of the outer case 2, and it can prevent effectively contacting the water tank 6 and the outer case 2. FIG. According to studies by the present inventors, it has been confirmed that it is desirable to provide the second virtual line L2 so as to form an angle of 30 ° to 60 °.

  Further, the height between the lowest point of the lead wire 31 and the outer box side fixing portion 33 is higher than the distance A in the height direction between the lowest point of the lead wire 31 and the lead wire lead-out portion 32. The distance B in the vertical direction is configured to be larger. At this time, from the viewpoint of suppressing the stress of the lead wire 31, it is desirable to provide the lead wire 31 in a state having sufficient deflection. However, the lead wire lead-out portion 32 is provided with respect to the bottom portion (the base plate 4) of the outer box 2. Since it cannot be positioned sufficiently upward, the distance A in the height direction between the lowest point of the lead wire 31 and the lead wire lead-out portion 32 cannot be increased so much. On the other hand, by increasing the distance B in the height direction between the lowest point of the lead wire 31 and the outer box side fixing portion 33, a sufficient slack of the lead wire 31 can be secured, and stress can be reduced. Effective for suppression.

  In the present embodiment, the bundling portion 37 is provided at a position excluding the lowest point between the lead wire lead-out portion 32 and the outer box side fixing portion 33 of the lead wire 31. By providing the bundling portion 37 at an appropriate position of the lead wire 31, it is possible to prevent a plurality of wires constituting the lead wire 31 from spreading apart and coming into contact with other members. At this time, if the bundling portion 37 is provided at the lowermost portion of the lead wire 31, the lowermost portion may become a node of the link, which may cause stress, but the bundling portion 37 is at a position excluding the lowest point. Therefore, such stress can be prevented.

  In the present embodiment, since the outer box side fixing portion 33 is configured to hold the lead wire 31 so as to extend in the vertical direction, the lead wire 31 is held without being stressed in the outer box side fixing portion 33 portion. be able to. The lead wire 31 has a slack in the vertical direction between the lead wire lead-out portion 32 and the outer box side fixing portion 33 and is not bent in the horizontal direction. If the lead wire 31 is bent in the horizontal direction, that is, if it is S-shaped or U-shaped as viewed from above, the lead wire 31 can be easily contacted with the water tank 6 or the outer box 2. By making it a non-bending state in the horizontal direction, it can be arranged in a state in which it is difficult to contact the water tank 6 or the outer box 2.

  As described above, according to the present embodiment, the lead wire 31 drawn out from the lead wire lead-out portion 32 of the drive mechanism portion 17 is configured to obtain a predetermined arrangement on the lower side in the outer box 2. Thereby, it can prevent that the bending part of the lead wire 31 contacts the water tank 6 or the outer case 2 as much as possible, suppressing the stress with respect to the lead wire 31, and can arrange | position the lead wire 31 appropriately. There is an excellent effect.
