  • Patent number: 9994991
    Abstract: A full-automatic washing machine includes: a first control part, a receiving part, a body display part arranged on an upper panel, and a remote controller separated from the body display part. The remote controller includes: setting keys for setting operating information of a washing operation, a second control part, an information display part and a transmitting part. The second control part displays operating information set by the setting keys through the information display part, and transmits the operating information by the transmitting part to the receiving part through wireless communication. A mode display part of the body display part is illuminated in a color such as blue corresponding to the reception of the operating information until the washing operation starts when the first control part receives the operating information.

  • 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).

  • Patent number: 5675976
    Abstract: Freezing is prevented when either of two blow ports of a bidirectional blow air-conditioner is closed. A first blowing fan is disposed on one of the sides of a heat exchanger on the utilization side and a second blowing fan is disposed on the other side. First and second blow ports are so disposed as to correspond to these showing fans, respectively, and a flap is operable to close the first blow port. The blow quantity of the second blowing fan, when the flap closes the first blow port, is controlled to a value greater than the blow quantity of the second blowing fan when the flap does not close the first blow port.

  • Patent number: 5603225
    Abstract: A multi-type air conditioner address setting method and address setting device for automatically setting an address with a simple structure. A dummy address sent from an exterior device is stored in an interior device. The interior device determines whether the interior device itself is operating in a designated operation mode. When the interior device is operating in the designated operation mode, the dummy address is set as an actual address. When an address request signal is sent from the exterior device, the set address is sent back thereto.
