2. Description of Related Art
Laundry cleaning machines on the domestic household market and machines on the commercial coin-laundromat market today require human labor to put laundry in or take out from the laundry cleaning machine. Existing systems lack automated operation to facilitate convenient use. Besides, current clothes cleaning systems (laundry washing machine without robotic arms, for example, ordinary washers or dryers) require human labor to close the door after putting laundry in, and do not have the ability to identify which customer is retrieving their laundry. Existing laundry machines also lack heat recycling ability with which to dry laundry faster and/or preheat water for the washing cycle.
Several design challenges listed below have not yet been tackled by the laundry machine industry. 1. The provision of a laundry container conveying device to transport laundry containers within the system. 2. The provision of a method for loading and unloading washing machines and clothes dryers from laundry container. 3. The provision of a system to identify which customer is collecting or loading their laundry, and to identify which laundry belongs to them. 4. Heat recycling ability to dry laundry faster and/or preheat water for washing cycle.
