FIG. 1 is an exploded perspective view of a main part showing an embodiment of a washing machine of the present invention, FIG. 2 is a vertical side view of the same, and the overall configuration of the washing machine will be described. An outer box 2 is disposed on a bottom frame 1 A water tub 5 is swingably disposed in the outer box 2 via a vibration isolating mechanism using a suspension plate 3 and a vibration isolating suspension rod 4. The dewatering tank 7 is rotatably arranged.

  In the figure, 8 is an autobalancer provided at the upper edge of the washing and dewatering tub 7, 15 is a water supply valve, 10 is a lid detachably attached to the upper surface opening of the outer box 1, and this lid 10 is attached to the top cover 11. It is done. A drive mechanism such as a motor 9 is disposed below the water tank 5.

  In the case of a washing machine having a drying function, a circulation air passage 12 having a dehumidifying plate 13 disposed therein is formed between the washing and dewatering tub 7 and the water tub 5 as shown in FIG. A drying unit 14 incorporating a heater and a fan was provided at the upper end portion of 12.

  In the case of the washing machine shown in FIG. 2, the washing / dehydrating tub 7 is disposed in the outer box 2 in a forward inclined state so that the laundry in the washing / dehydrating tub 7 can be easily taken out.

  In the washing machine having such a configuration, the left and right side plates 16 made of a metal material as shown in FIG. 1, the resin front panel 18 covering the front opening, and the back plate 17 shown in FIG. The left and right side plates 16 are connected by an elongated plate-like back plate 19 at the upper portion on the back side, and are connected by an upper plate-like plate 20 at the upper portion on the front opening 21 side.

  In the present invention, the power supply substrate 22 is disposed below the front opening 21. The power supply board 22 is provided with, for example, a capacitor 23, an IPM, a heat sink 24, a relay 25, and the like, and a lead wire 27 is connected via a connector 26.
