Hereinafter, the coin laundry system according to the embodiment will be described in detail with reference to the attached drawings. In each figure, the same components are designated by the same reference numerals.

(First Embodiment)
As shown in FIGS. 1 and 2, the coin laundry 1 in which the coin laundry system of the first embodiment is introduced provides a self-service laundry service to a user by installing a plurality of laundry devices in a store. Laundry equipment includes, for example, a washing machine, a dryer, a washer-dryer, a shoe washer, a compression pack machine, and the like. The coin laundry 1 in which a plurality of machines 2B are installed is shown. The user selects the equipment to be used from the vacant washer-dryer 2A and dryer 2B, and throws in the clothes to be washed (that is, the clothes to be washed and the clothes to be dried), and is washed or dried. Alternatively, wash and dry. In addition, there are cases where, for example, a clerk performs a laundry agency service on behalf of the user.

In the coin laundry 1, a centralized settlement machine 3 that centrally manages the laundry equipment in the store is arranged. The user selects the washing / drying menu according to the operation guidance of the centralized settlement machine 3, and by prepaid or postpaid the usage fee, the washer / dryer 2A and the dryer 2B can be washed and / or dried according to the desired course. Let it run.

In the coin laundry 1, a user area 4 and a maintenance area 41 are provided, as shown in the plan view of FIG. Although not shown, tables and chairs for users are arranged in the user area 4. The user spends a waiting time in the user area 4 and folds clothes and the like that have been washed and dried. The maintenance area 41 is an area used by persons concerned with the coin laundry 1, and is used when inspecting and maintaining the laundry equipment and the centralized settlement machine 3. Utility equipment such as electrical wiring for laundry equipment, water supply / drainage pipes, water supply / exhaust pipes, and valves are arranged in the maintenance area 41. The maintenance area 41 preferably has a shutter 43 on the outer wall 42 on the back side. For example, by opening the shutter 43 to install the laundry equipment and carry in the maintenance equipment, the installation of the laundry equipment can be facilitated and the space of the maintenance area 41 can be saved. Note that FIG. 2 illustrates the rectangular user area 4 and the maintenance area 41 as an example, but it does not have to be rectangular.

The user area 4 and the maintenance area 41 are separated by an interior wall 44. The interior wall 44 is formed of, for example, wood, a metal material, a resin material, or a combination thereof. A functional material such as a soundproofing material or a heat insulating material may be laminated on the maintenance area 41 side. The surface of the interior wall 44 on the user area 4 side is painted or wallpapered so as to bring an aesthetic appearance to the coin laundry 1.

The interior wall 44 is formed with a plurality of openings 45 so that the portions of the doors 21A and 21B of the washer / dryer 2A and the dryer 2B are exposed on the user area 4 side. The opening 45 has, for example, a shape similar to the outer peripheral shape of the doors 21A and 21B. That is, the interior wall 44 is located as a protective wall on the front side of the washer / dryer 2A and the dryer 2B except for the doors 21A and 21B, and for the user, the inside of the washer / dryer 2A and the dryer 2B is located. It is a safety wall against moving parts. The interior wall 44 may be provided with an opening for providing a display unit for the washer / dryer 2A and the dryer 2B, and a maintenance opening used for maintenance by a person concerned with the coin laundry 1. The maintenance opening is locked by providing a door so that the user cannot use it, for example. Further, the interior wall 44 is formed with an opening 46 so that the operation portion of the user of the centralized settlement machine 3 is exposed.

In the washer / dryer 2A and the dryer 2B, the outer panel (that is, the exterior body), which is indispensable when the product is completed by one unit, is omitted. Further, the washer / dryer 2A and the dryer 2B are referred to as the minimum necessary equipment (referred to as "individual component") excluding the equipment that can be shared (referred to as "shared component") on the premise that a plurality of dryers 2B are installed. ) Each of the main unit is configured. As an example, the main body unit is composed of, for example, a drum for loading an object to be washed or an object to be dried and a drive system thereof. Shareable equipment such as gas burners, blowers, and lint filters shall be 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 body unit perform washing / drying. The outer panel does not have to be completely omitted, and a part of the outer panel may be left. For example, a drive device such as a motor may be enclosed as a safety cover.

3 and 4 show, as an example, the main body unit of the drum type dryer 2B, which is unitized in two stages, upper and lower. The main body unit of the drum type dryer 2B may be a unit in two rows on the left and right. Further, it may be a unit having two rows of upper and lower rows and two rows of left and right. That is, the combination of up, down, left, and right can be freely selected.

In the main body unit of the upper and lower two-stage drum type dryer 2B, for example, the shells 5A and 5B formed in a substantially cylindrical shape are fixedly arranged on the frame 50 formed in the upper and lower two-stage rack shape. The frame 50 and the shells 5A and 5B are connected by a support member (not shown) such as a damper. The frame 50 is fixed on a foundation 100 such as concrete by, for example, anchor bolts 101. The frame 50 is made of, for example, a metal material. The cylindrical drums 51A and 51B are rotatably provided inside the shells 5A and 5B. On the side peripheral surfaces of the drums 51A and 51B, a large number of ventilation holes 52A and 52B are formed to allow moisture evaporated from the object to be dried and warm air for drying to pass through. The shells 5A and 5B and the drums 51A and 51B have an opening on the front side, and serve as a loading port for taking in and out the object to be dried. The door 21B for opening and closing the slot may be provided on the shells 5A and 5B, or may be provided on the interior wall 44.

The back side of the drums 51A and 51B is bottomed, and the rotating shafts 53A and 53B extending along the center line of the drums 51A and 51B are connected. The rotating shafts 53A and 53B are rotatably supported by bearing mechanisms 54A and 54B such as bearings arranged outside the shells 5A and 5B. The pulleys 55A and 55B provided at the ends of the rotating shafts 53A and 53B are connected to the 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 rotation speed adjusted by, for example, an inverter or a speed reducer.

The shells 5A and 5B are formed with intake passages 6A and 6B for introducing warm air and exhaust passages 61A and 61B for exhausting warm air. The intake pipes 64A, 64B and the exhaust pipes 65A, 65B are connected to the intake ports 62A, 62B and the exhaust ports 63A, 63B arranged on the back side of the shells 5A, 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 heats the outside air to generate warm air is arranged at the confluence point or upstream thereof. The heating device 7 is, for example, a burner that burns and heats gas. That is, the heating device 7 shared by the upper and lower shells 5A and 5B is one of the shared units. In addition, in FIGS. 3 and 4, one heating device 7 is shared by the upper and lower shells 5A and 5B, but when a plurality of main body units are installed in the maintenance area 41, other main body units may be used. The heating device 7 may be shared.

The exhaust pipes 65A and 65B connected to the exhaust ports 63A and 63B of the upper and lower shells 5A and 5B are connected to, for example, the collective exhaust duct 71 arranged on the ceiling side of the maintenance area 41 (see FIG. 2). ). Valves 66A and 66B for adjusting the air volume are provided in the exhaust pipes 65A and 65B, respectively. The collective exhaust duct 71 is connected to an outdoor unit 72 provided outside the maintenance area 41. A blower 72a, which is an exhaust device that exhausts warm air from the shells 5A and 5B, is arranged in the outdoor unit 72 (see FIG. 2). The blower 72a is, for example, a sirocco fan type blower. In addition to the blower 72a, a lint filter 72b is provided in the outdoor unit 72. That is, the blower 72a and the lint filter 72b shared by the upper and lower shells 5A and 5B are one of the shared units. Instead of using the outdoor unit 72, a shared blower 72a and lint filter 72b may be arranged indoors.

In the above configuration, when the blower 72a operates during drying and the valves 66A and 66B are opened, the pressure inside the shells 5A and 5B becomes negative, and warm air is introduced from the intake passages 6A and 6B. The air volume of the warm air in the shells 5A and 5B is determined by, for example, detecting the temperature and humidity in the shells 5A and 5B with a sensor and adjusting the opening degree of the valves 66A and 66B based on the detection result. When operating only one of the upper and lower two-stage dryers 2A, for example, the upper-stage dryer 2A, only the valve 66A is opened and the valve 66B is left closed. Although FIG. 2 shows a configuration in which the outdoor unit 72 and the collective exhaust duct 71 are shared by all the main body units installed in the maintenance area 41, a plurality of outdoor units 72 and the collective exhaust duct 71 are provided and shared only by the unit unit. It may be configured to be used. The lint filter may also be provided in the exhaust passages 61A and 61B of the shells 5A and 5B to disperse the load with the lint filter 72b of the outdoor unit 72.
