  The laundry dryer 2A and the dryer 2B omit an outer panel (that is, an exterior body) that is essential when a single product is used. Furthermore, on the premise that a plurality of washing / drying machines 2A and 2B are installed, the minimum necessary equipment (referred to as “individual constituent elements”) excluding sharable equipment (referred to as “shared constituent elements”). ) Constitute the main unit. As an example, for example, a main body unit is configured by a drum into which an object to be cleaned or an object to be dried is charged and a drive system thereof. A sharable device such as a gas burner, a blower, or a lint filter is separately configured as a shared unit. The shared component of the shared unit is shared when the individual components of the washer / dryer 2A and the dryer 2B constituting the main unit perform washing and drying. It should be noted that the outer panel does not have to be entirely omitted, and a part of the outer panel may be left. For example, a driving device such as a motor may be enclosed as a safety cover.

Furthermore, it is good also as a unit of 2 steps | paragraphs of upper and lower 2 steps right and left. That is, a combination of up, down, left and right can be freely selected.

  In the main body unit of the upper and lower two-stage drum dryer 2B, for example, shells 5A and 5B formed in a substantially cylindrical shape are fixedly arranged on a frame 50 formed in a two-stage upper and lower rack shape. The frame 50 and the shells 5A and 5B are connected by a support member (not shown) such as a damper, for example. The frame 50 is fixed by, for example, anchor bolts 101 on a foundation 100 such as concrete. The frame 50 is made of, for example, a metal material. Cylindrical drums 51A and 51B are rotatably provided inside shells 5A and 5B. On the side peripheral surfaces of the drums 51A and 51B, a large number of air holes 52A and 52B are formed through which moisture evaporated from the material to be dried and hot air for drying pass. The shells 5A, 5B and the drums 51A, 51B are open on the front side and serve as inlets for taking in and out the objects to be dried. The door 21 </ b> B that opens and closes the inlet may be provided in the shells 5 </ b> A and 5 </ b> B or may be provided on the indoor wall 44.

  The back sides of the drums 51A and 51B are bottomed, and are connected to rotating shafts 53A and 53B extending along the center lines of the drums 51A and 51B. The rotary shafts 53A and 53B are rotatably supported by bearing mechanisms 54A and 54B such as bearings arranged outside the shells 5A and 5B. Pulleys 55A and 55B provided at the ends of the rotary shafts 53A and 53B are connected to pulleys 57A and 57B provided on the motors 56A and 56B via endless belts 58A and 58B. The motors 56A and 56B rotate the drums 51A and 51B at a rotational speed adjusted by, for example, an inverter or a speed reducer.

  In the shells 5A and 5B, intake passages 6A and 6B for introducing warm air and exhaust passages 61A and 61B for exhausting warm air are formed. Intake pipes 64A and 64B and exhaust pipes 65A and 65B are connected to the intake openings 62A and 62B and the exhaust openings 63A and 63B arranged on the back side of the shells 5A and 5B. The intake pipes 64A and 64B connected to the upper and lower two-stage intake ports 62A and 62B merge on the upstream side to form one pipe (intake pipe). For example, the heating device 7 that generates warm air by heating the outside air is disposed at the junction or upstream thereof. The heating device 7 is a burner that burns and heats gas, for example. That is, the heating device 7 shared by the upper and lower two-stage shells 5A and 5B is one of the shared units. 3 and 4, the two upper and lower shells 5A and 5B share one heating device 7. However, when a plurality of main units are installed in the maintenance area 41, other main units may be used. It is good also as a structure which shares the heating apparatus 7. FIG.

In the outdoor unit 72, a lint filter 72b is provided in addition to the blower 72a. That is, the blower 72a and the lint filter 72b shared by the upper and lower two-stage shells 5A and 5B are one of the shared units. In addition, you may arrange | position the air blower 72a and the lint filter 72b which are not shared with the outdoor unit 72 indoors.

  In the above configuration, when the blower 72a is actuated when the drying is performed and the valves 66A and 66B are opened, the inside of the shells 5A and 5B becomes negative pressure, and hot air is introduced from the intake passages 6A and 6B. The amount of warm air in each shell 5A, 5B is determined by, for example, detecting the temperature and humidity in the shell 5A, 5B with a sensor and adjusting the opening of the valves 66A, 66B based on the detection result. When only one of the upper and lower dryers 2A, for example, the upper dryer 2A is operated, only the valve 66A is opened and the valve 66B is kept closed. In FIG. 2, all the main unit units installed in the maintenance area 41 are configured to share the outdoor unit 72 and the collective exhaust duct 71. However, a plurality of the outdoor units 72 and the collective exhaust duct 71 are provided and shared only in units. It is good also as composition to do. A lint filter may also be provided in the exhaust passages 61A and 61B of the shells 5A and 5B so as to distribute the load with the lint filter 72b of the outdoor unit 72.
