The washing water detergent supply system is collectively provided on the upper left side in the outer frame housing 1.

  As shown in FIGS. 2 and 5, the drying duct 29 is installed in the vertical direction inside the back surface of the outer frame housing 1. The drying duct 29 is connected to a suction port 2a provided at the lower part of the back of the outer tub 2 with a rubber bellows tube B29a. A water-cooled dehumidifying mechanism (not shown) is built in the drying duct 29, and cooling water is supplied from the water supply electromagnetic valve 16 to the water-cooled dehumidifying mechanism. The cooling water flows down along the wall surface of the drying duct 29, enters the outer tub 2 from the intake port 2a, and is discharged from the drain port 2b.

  The upper part of the drying duct 29 is connected to a filter duct 27 installed in the front-rear direction on the upper right side in the outer frame housing 1 as shown in FIGS. The filter duct 27 has an opening on the front surface, and a drawer-type drying filter 8 is inserted into the opening. The air that has entered the filter duct 27 from the drying duct 29 flows into the mesh filter 8a of the drying filter 8, and lint is removed.

  Cleaning of the dry filter 8 is performed by pulling out the dry filter 8 and taking out the mesh filter 8a. In addition, an opening is provided on the lower surface of the dry filter insertion portion of the filter duct 27, and the opening is connected to the intake duct 33, and the other end of the intake duct 33 is connected to the intake port of the blower unit 28. ing.

  As shown in FIGS. 2 and 4, the hot air duct 30 is connected to a hot air outlet 32 provided in the outer tank cover 2d via a rubber bellows tube 30a and a bellows tube joint 30b. Since the blower unit 28 is provided on the upper right side in the housing 1, the hot air outlet 32 is provided at an upper right position of the outer tub cover 2d so that the distance to the hot air outlet 32 is as short as possible. It is.

  These dry duct 29, filter duct 27, dry filter 8, intake duct 33, blower unit 28, heater, bellows tube 30a and the like are referred to as a dry air circulation system. This dry air circulation system has a structure in which the dry air flowing out from the lower rear part of the outer tub is dehumidified and guided upward above the blowing means, heated by a heater, and again sent to the front upper part of the outer tub. Therefore, they are collectively provided on the upper right side of the outer frame housing 1.

  Since the washing water detergent supply system described above is on the upper left side in the outer frame housing 1 and the dry air circulation system is on the upper right side in the outer frame housing 1, the washing water detergent supply system and the dry air circulation system are on the outer frame. The housing 1 is arranged in the left and right direction as viewed from the front side.

  The speaker 100 is provided on the lower right surface of the front reinforcing plate 1g as shown in FIGS. 7 and 10, and is fastened to the reinforcing plate 1g using two screws 101 as shown in FIG. . The speaker 100 generates sound by an electrical signal of information supplied from the control circuit shown in FIG. The information provided by the speaker 100 by voice is content related to the washing operation and the drying operation of the washing / drying machine.

  The control circuit includes a microcomputer 120, a load driving means 121, various loads, a power supply circuit, various sensors, various switches, a speaker 100, and a sound generation IC 122. The microcomputer 120, the load driving means 121, and the sound generation IC 122 are incorporated in the control board to form the control device 38. As shown in FIGS. 6 to 8, the control device 38 is provided on the front side of the bottom base 1 h constituting the outer frame housing 1. The control device 38 is housed in a control box in order to avoid dust and water droplets. As shown in FIG. 8, the speaker 100 is connected to a sound generation IC 122 provided in the control device 38 by a lead wire 150.

  Since the speaker 100 is provided on the lower right surface of the front reinforcing plate 1g, the speaker 100 is located at the lower side away from the washing water detergent supply system and the dry air circulation system and on the opposite side of the washing water detergent supply system. It will be. For this reason, even if washing water or detergent is dropped from the washing water detergent supply system, it is possible to avoid adhering to the speaker 100. As a result, it is possible not only to avoid failure and rust due to water adhesion to the speaker, but also to prevent the insulation resistance from being lowered due to water adhesion and to eliminate the risk of electric shock when the user touches the main body.

  Since the speaker 100 is screwed to the front reinforcing plate 1g made of a thick steel plate, it is attached to the front cover 1c of a synthetic resin plate material or the outer plates 1a, 1b made of a thin steel plate. In contrast, information is provided in good sound quality and easy to hear.

  In addition, since the speaker 100 is placed on the front side of the front reinforcing plate 1g, unlike the case where it is placed on the inner side, the speaker 100 is easy to hear without being muffled.

  Further, since the speaker 100 is attached near the lower corner of the front reinforcing plate 1g, the speaker 100 is placed away from the washing water detergent supply system and the dry air circulation system. For this reason, since it is difficult to be affected by the heat from the dry air circulation system, the temperature does not rise, heat resistance is not required for the speaker, and it is not necessary to use an expensive speaker.

  Furthermore, there is no contact or interference with parts constituting the washing water detergent supply system or the dry air circulation system, and the assembly work is easy. In addition, since it is close to the control device 38 that supplies an electrical information signal to the speaker 100, the lead wire 150 is short, wiring is easy, and noise can be avoided.
