  As shown in FIG. 2, the rotating drum 10 indicated by a broken line is provided in the housing 1 and stores clothes as a cylindrical washing and dewatering tub that is rotatably supported. The rotary drum 10 has an opening 10a for putting clothes in and out on the front side end face, and a plurality of through holes (not shown) for water flow and ventilation on the peripheral wall and the bottom wall. . A fluid balancer 10b integrated with the rotary drum 10 is provided at the edge of the opening 10a. Further, a plurality of lifters 10c extending in the depth direction are provided on the inner peripheral wall of the rotary drum 10. When the rotary drum 10 rotates during washing and drying, clothes are lifted along the peripheral wall by the lifter 10c and centrifugal force, and gravity is applied. The movement of falling is repeated. The rotation center of the rotary drum 10 is inclined so that the opening 10a side becomes higher.

  The outer tub 20 includes the rotary drum 10 coaxially and is formed in a cylindrical shape having an open front surface, and the inside functions as a washing room and a drying room. An opening on the front surface of the outer tub 20 is provided with an outer tub cover 20 a made of a synthetic resin, and water can be stored in the outer tub 20. An opening 20b for taking in and out clothing and the like is formed in the front center of the outer tub cover 20a. The opening 20b and the opening provided in the front reinforcing member are connected by rubber packing. This packing plays the role of maintaining the water tightness between the outer tub 20 and the door 2. This prevents water leakage during washing, rinsing and dehydration. A drain port 20 c is provided on the bottom surface of the outer tub 20, and a drain hose 8 is connected thereto.

  The lower part of the outer tub 20 is supported by a plurality of anti-vibration means 11 (consisting of coil springs and dampers) whose lower side is fixed to the base 9. The upper portion of the outer tub 20 is supported by an auxiliary spring (not shown) attached to the upper reinforcing member, and is configured to prevent the outer tub 20 from falling in the front-rear direction.

  The front end portion of the drainage hose 8 is connected to a drainage hole provided on the floor surface. In addition, a drain valve 21 is provided in the middle of the drain hose 8, water is stored in the outer tub 20 by closing the drain valve 21 and supplying water, and opening the drain valve 21 in the outer tub 20. Water is discharged outside the aircraft.

  The motor 30 rotates the rotary drum 10 and is provided at the center of the back surface of the outer tub 20. The rotating shaft 31 of the motor 30 passes through the outer tub 20 and is coupled to a metal flange 10e provided on the back surface of the rotating drum 10.

  Further, the washing and drying machine of the present embodiment includes a blower duct 40 inside the housing 1. The blower duct 40 has a rear duct 42 that extends in the vertical direction on the back side of the outer tub 20, and an upper duct 43 that extends on the upper surface side of the outer tub 20 from the rear to the front. The lower part of the rear duct 42 is connected substantially horizontally to the bellows 41 having a flexible structure at an outlet 20d provided at the lower back of the outer tub 20. A water-cooled dehumidifying mechanism (not shown) is provided in the rear duct 42.

  A blower fan unit 45 including a fan 46 as a blower and a heater 47 as a heater is provided on the downstream side of the upper duct 43. When the blower fan unit 45 is activated, air is taken into the blower fan unit 45 from the upper duct 43 by the suction force of the fan 46, and the taken-in air is heated by passing through the heater 47. Are discharged from a discharge port (not shown). Further, when the air passes through the rear duct 42, it is cooled by the water-cooled dehumidifying mechanism and dehumidified. The heated air discharged from the blower fan unit 45 is supplied into the rotary drum 10 via the hot air duct 35, the bellows 36, and the blowing nozzle 37.

  Next, the structure of the housing bottom part in the present embodiment will be described. The bottom of the housing of the present embodiment is composed of a base 91 on which the housing main body is placed and a base front cover 92 (FIG. 6) that covers the front surface of the base 91. The base 91 is integrally formed as a frame body that surrounds four sides by a front surface 91f, left and right side surfaces 91a, and a back surface (not shown).

  FIG. 3 is a perspective view showing a state where the lower front cover 1f of the washing / drying machine in the present embodiment is removed. The lower front cover 1f forms a design surface together with the front cover 1c, and a part of the lower front cover 1f also serves as a lint filter lid 1ff for collecting lint of the laundry. Further, the lower front cover 1f is provided with an engagement element (not shown) on the back side of both side end portions thereof, and is detachable between engagement grooves provided on the left and right side plates 1a. .

  The base front cover 92 is also configured to be completely removable from the front surface 91f of the base 91 as shown in FIG. Specifically, an engaging element 92h as shown in FIG. 5 is provided on the back side of the base front cover 92, and it can be attached to and detached from an engaging groove 91t provided on the front face 91f of the base 91. . A plurality of reinforcing ribs 92m are provided in the vertical direction on the back surface of the base front cover 92 to ensure the strength of the base front cover 92.

  Furthermore, a fastening hole 1fk is provided in the lower part of the lower front cover 1f, a fastening hole 92k is provided in the upper part of the base front cover 92, and a fastening hole 91k is provided in the upper part of the front surface 91f of the base 91. The lower front cover 1f and the base front cover 92 are fastened to the base 91 with a common screw. Therefore, if this common screw is removed, not only the lower front cover 1f but also the base front cover 92 can be easily removed.

  Next, how to attach and remove the control device 12 electrically connected to the motor 30 will be described.

  As shown in FIG. 9, the base 91 in this embodiment includes a locking portion 91 x that supports the front surface side of the control device 12, a locking portion 91 y that supports the back surface side of the control device 12, and the bottom surface of the control device 12. A locking portion 91z that supports the side is provided. And the overhang | projection part 12h provided in the lower part by the side of the back surface of the control apparatus 12 fits the fitting part 91u provided in the latching | locking part 91y of the base 91, and thereby the control apparatus 12 of the housing | casing 1 is made. Fixed to the bottom. For this reason, by pushing the upper part of the control device 12 in the depth direction of the housing, the fitting of the projecting portion 12h at the lower part of the control device 12 is released, and the control device 12 can be taken out.

  Here, the front surface 91 f of the base 91 is opened upward, and the opening width is larger than the width dimension of the control device 12. Therefore, if the lower front cover 1f and the base front cover 92 are removed as shown in FIG. 7, the controller 12 can be pulled out from the housing 1 while being tilted as shown in FIG.

  Conventionally, when maintenance of the piping located under the outer tub 20 is performed, it has been difficult to take out the control device 12, but in this embodiment, the base front cover 92, which is a separate body from the base 91, is removed, By using the notch formed in the upper part of the front surface 91f of 91, the operation | work which removes the control apparatus 12 becomes markedly easy. Of course, the control device 12 itself can be easily inspected.

  Further, the front surface 91f of the base 91 is not completely cut out to the height of the bottom surface of the base 91, but a wall surface is formed at the height of the locking portion 91x, so that the control device 12 does not roll over completely, It is also possible to hold it in a tilted state to some extent.
