Patent number: 8336326Abstract: Provided is a dispenser including an ice-making water tank for storing ice-making water and an auger-type ice-making machine for producing ice chips by freezing the ice-making water in the ice-making water tank. The auger-type ice-making machine includes a refrigeration casing into which the ice-making water is supplied, and the refrigeration casing and the drain pan are connected to each other through the intermediation of an ice-making water drain pipe. The ice-making water in the refrigeration casing is drained at predetermined time points, and the drain pan is washed with the ice-making water thus drained.Type: GrantFiled: December 2, 2009Date of Patent: December 25, 2012Assignee: Hoshizaki Denki Kabushiki KaishaInventors: Makoto Sasaki, Motohiro Kawachi, Kouichi Itou, Hiroshi Nagai

Patent number: 8286444Abstract: Provided is a dispenser in which a wash water discharge opening provided to a drain pan is connected to an external tap water system via a wash water supply path. The wash water supply path is provided with a wash water supply valve for controlling whether or not to supply wash water to the drain pan. Based on delivery information output from a delivery control section for controlling delivery of ice chips, a wash control section in a controller judges whether or not a delivery count of the ice chips has reached a predetermined set count, and, when it is judged that the delivery count has reached the set count, opens the wash water supply valve to perform a wash action.Type: GrantFiled: December 2, 2009Date of Patent: October 16, 2012Assignee: Hoshizaki Denki Kabushiki KaishaInventors: Makoto Sasaki, Kouichi Itou, Yuji Hirano, Motohiro Kawachi, Hiroshi Nagai

The wash water supply path is provided with a wash water supply valve for controlling whether or not to supply wash water to the drain pan. A wash control section in a controller performs timing separately from control of a generation/delivery control section for performing generation and delivery of ice chips, and also performs a wash action at predetermined time intervals by opening the wash water supply valve.Type: GrantFiled: December 2, 2009Date of Patent: October 16, 2012Assignee: Hoshizaki Denki Kabushiki KaishaInventors: Makoto Sasaki, Hiroshi Nagai, Kouichi Itou, Yuji Hirano, Motohiro Kawachi, Seiki Hosaka
