  • Patent number: 10508376
    Abstract: A washing machine is provided. The washing machine includes: a washing/dewatering drum for accommodating the washings; an electric motor for driving the washing/dewatering drum to rotate; and a microcomputer. In a rinsing process of a washing operation in a water saving mode, the microcomputer continuously performs a dewatering-rinsing process for a plurality of times rather than executing a water-storage rinsing process for rotating a rotating wing while water stored in the washing/dewatering drum reaches a specified water level. The dewatering-rinsing process includes: a water supplying process of supplying water to the washing/dewatering drum so that the washings are saturated by water, and an intermediate dewatering process or a final dewatering process executed immediately after the water supplying process. A maximum rotating speed of the motor in the intermediate dewatering process immediately before the water supplying process is lower than a maximum rotating speed in the final dewatering process.

  • Patent number: 9238884
    Abstract: 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.

  • Patent number: 8844324
    Abstract: 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.

  • Patent number: 8739576
    Abstract: 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).

  • Publication number: 20090260404
    Abstract: The present invention provides a washing machine configured such that a gas having a cleaning function is prevented from leaking to the outside. The washing machine performs an ozone cleaning step for cleaning dry laundry by supplying ozone to the laundry prior to a washing step. Before the start of the ozone cleaning step, a dehumidification water valve (14) is opened to once retain dehumidification water in a bottom of an outer tub (7). Then, water is retained in an overflow trap (45) by utilizing the dehumidification water, whereby a flow passage extending from the outer tub (7) to the outside is sealed with the water. Further, a detergent valve (55) or a finishing agent valve (56) is opened to retain water in a water supply trap (24), whereby a flow passage extending from the outer tub (7) to the outside is sealed with the water.

  • Publication number: 20090255299
    Abstract: The present invention provides a clothe drier, a washing machine and a washing machine with a clothes drying function, which are improved in the effects of cleaning, deodorizing and sterilizing clothes with ozone, and permit easy replacement of an ozone generation element or safe control of the ozone. An ozone generator (40) generates ozone by applying silent discharge to air introduced therein. The ozone is sucked into a drying air duct (15) by rotation of a blower (20) and a drum (3) and mixed in air heated by a heater (21), and the resulting mixture is supplied into the drum (3) through an inlet (17). Thus, the ozone is supplied to clothes to be dried, thereby effectively deodorizing and sterilizing the clothes. Since the ozone generator (40) is disposed away from the drying air duct (15), the ozone generation element can be easily replaced.

  • Publication number: 20090049874
    Abstract: The washing machine (1) of the invention is a washing machine (1) having a drying function. The washing machine (1) has an ozone generator (47) for supplying ozone to a dry air duct (16) and also has an air wash key (77) for instructing the execution of air wash. Operating the air wash key (77) performs the air wash operation as a treatment independent of washing and drying. In the air wash operation, a blower (21) is turned on and the ozone generator (47) is turned on, and air containing ozone is supplied to clothes stored in a drum (3) to sterilize/deodorize the clothes. In this operation, whether to rotate the drum (3) or to perform the air wash operation with the drum (3) stopped can be selected.

  • Publication number: 20040172985
    Abstract: An electric washing machine according to the present invention performs a washing process with the use of electrolyzed water. When the level of supplied water reaches an electrolyzing water level which is lower than a washing water level, energization of an electrolyzing device (31) is started. At this time, air is supplied into an electrolyzing chamber (32) by an air pump (89), so that water in the electrolyzing chamber (32) is caused to flow, thereby assisting efficient electrolysis of the water. The water thus electrolyzed has an enhanced cleaning capability thereby to improve the washing performance of the washing machine.
