Patent number: 10480114Abstract: A drum washing machine, including: a driving part, capable of operating in a uniaxial driving form and a biaxial driving form; a heater configured to heat water stored in the outer drum for washing; and a control part which at least performs washing operation of a first washing mode and a second washing mode. In a washing process of the first washing mode, the control part enables the driving part to operate in the uniaxial driving form and also enables the heater to operate. Further, in a washing process of the second washing mode, the control part enables the driving part to operate in the biaxial driving form and also enables the heater to operate in such a manner that heat applied to the water is reduced compared with the first washing mode.Type: GrantFiled: July 7, 2016Date of Patent: November 19, 2019Assignees: HAIER ASIA CO., LTD., QINGDAO HAIER WASHING MACHINE CO., LTD.Inventors: Shigeharu Nakamoto, Hiromi Hirota, Harumi Takeuchi, Takahiro Tsuji, Satoshi Hirose, Masanori Yoneda

Patent number: 10329702Abstract: A drum washing machine is provided. The drum washing machine includes: an outer tank arranged in a housing; a drum, which is arranged in the outer tank and capable of rotating about a horizontal shaft H; a rotating body, which is arranged at a rear part of the drum, a surface of the rotating body being provided with a projection; and a driving part, configured to drive the drum and the rotating body to coaxially rotate at different rotating speeds. The drum has a baffle arranged on an inner circumferential surface of the drum, which is used as a moving unit configured to move the washings in the drum towards the rotating body. The baffle has gathering surfaces for gathering the washings through a rotation of the drum. The gathering surfaces are inclined so that the side of the rotating body is lagged in a rotation direction of the drum.Type: GrantFiled: September 2, 2015Date of Patent: June 25, 2019Assignees: HAIER ASIA CO., LTD., QINGDAO HAIER WASHING MACHINE CO., LTD.Inventors: Hiromi Hirota, Harumi Takeuchi, Hiroyuki Tanaka, Takahiro Tsuji, Shigeharu Nakamoto

Patent number: 4762057Abstract: A controlling apparatus controls a series of processes such as a kneading process, a fermenting process, a breathing process and a baking process of material within a bread baking mold based on the temperature of the bread baking mold detected within the baking chamber. The controlling apparatus controls a series of process of at least two types or more and is adapted to select either of the subsequent series of processes in accordance with one temperature input or two temperature inputs each respectively sensed at the kneading start time-point, during the kneading process, or at the kneading completion time-point. Fresh-baked bread which is superior may be provided independent from the changing influences of the seasons or of the material temperatures.Type: GrantFiled: October 9, 1986Date of Patent: August 9, 1988Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiromi Hirota, Hirofumi Nakakura, Haruo Ishikawa, Hajime Oyabu, Akihisa Nakano, Toshiichiro Tanaka
