Patent number: 9238884Abstract: The inventive washing machine is capable of hygienically and properly performing a rinsing operation with the use of bathwater. The washing machine includes a bathwater pump (34), so that bathwater can be retained in a washing tub (3). A water circulation passage (42, 43, 44, 45, 15, 55, 25, 57, 26, 58, 59) is provided for circulating laundry water to the washing tub (3). The bathwater retained in the washing tub (3) is circulated through the water circulation passage, and ozone generated by an ozone generator (19) is mixed with the circulated water, whereby the water (bathwater) is cleaned. This water cleaning operation is performed in a rinsing step. When the ozone is supplied in the rinsing step, the ozone is effective to sterilize the bathwater and decompose dirt and odorant of laundry. Therefore, the rinsing operation to be performed in this manner is comparable to a rinsing operation to be performed with the use of tap water.Type: GrantFiled: October 8, 2008Date of Patent: January 19, 2016Assignees: HAIER GROUP CORPORATION, QINGDAO HAIER WASHING MACHINE CO., LTD.Inventors: Yukio Tobi, Haruo Mamiya, Takayoshi Akagi

Patent number: 8844324Abstract: The inventive washing machine is capable of advantageously rinsing laundry with clean water by performing a rinsing operation while cleaning water being used for the rinsing operation in a rinsing step. The washing machine includes a water circulation passage (42, 43, 44, 45, 15, 55, 25, 57, 26, 58, 59) for circulating laundry water to a washing tub (3). Rinsing water retained in the washing tub (3) can be circulated through the water circulation passage. Ozone generated by an ozone generator (19) is mixed with the circulated water, whereby the rinsing water is cleaned. This water cleaning operation is performed only in the rinsing step. Where the ozone is supplied only in the rinsing step, the ozone is effective to decompose dirt and odorant of the laundry. Thus, the rinsing operation is advantageously performed.Type: GrantFiled: October 8, 2008Date of Patent: September 30, 2014Assignees: Haier Group Corporation, Qingdao Haier Washing Machine Co., Ltd.Inventors: Yukio Tobi, Haruo Mamiya, Takayoshi Akagi

Patent number: 8739576Abstract: The inventive washing machine is capable of deodorizing a daily commodity with cleaning air in a shorter period of time. When the daily commodity is deodorized with the cleaning air, a control section (120) causes a heater (100) to heat air in a washing tub (3) to maintain an inside air temperature of the washing tub (3) within a predetermined temperature range. This promotes the deodorization with the cleaning air, as long as the cleaning air is not decomposed by the heating. As a result, the daily commodity can be satisfactorily deodorized irrespective of an operation period set by a timer (122), for example, even if a daily commodity deodorization process is performed with the use of the cleaning air in a shorter period of time (a minimum air-wash process is performed).Type: GrantFiled: September 4, 2008Date of Patent: June 3, 2014Assignees: Haier Group Corporation, Qingdao Haier Washing Machine Co., Ltd.Inventors: Yukio Tobi, Haruo Mamiya, Takayoshi Akagi

Patent number: 7138772Abstract: The invention provides an electrically movable vehicle drivable by a simplified mode of control and a control program for driving the vehicle. A normalized value Y? representing translation motion and a normalized value X? representing turning motion are fed from a command value input unit 110 to a velocity command value calculating unit 120. The calculating unit 120 determines a translation velocity command value Vg—trg based on the normalized value Y?. The calculating unit 120 determines a turn angular velocity command value ?f—trg that will always satisfy Expression (2–4) for preventing the vehicle from falling down. The translation velocity command value Vg—trg and the turn angular velocity command value ?f—trg determined by the unit 120 are fed to a control command value calculating unit 130, which calculates control command values for left and right drive wheels. The control command values are fed to a motor control unit 140 to control motors Mr, Ml and control the drive wheels.Type: GrantFiled: September 29, 2005Date of Patent: November 21, 2006Assignee: Sanyo Electric Co.
