  • Patent number: 9879372
    Abstract: A clothes dryer configured to cause air to flow through a drying chamber, an exhaust passage (an air passage) 103 and a filter by a blower to dry clothes includes a heat pump installed in the exhaust passage (103) and having a heat exchanger (122) including a refrigerant pipe (132) and a pin, and a flow velocity sensor (107) of airflow having a hot thermistor (a heat generating body) 107a and a temperature compensation thermistor (a temperature detecting body) 107b and installed downstream from the heat exchanger (122), wherein the thermistors (107a and 107b) are disposed at a refrigerant pipe (132) of the heat exchanger (122) in parallel.

  • 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.

  • Publication number: 20040148970
    Abstract: In a drum type washing machine according to the present invention, an electrolytic device 60 for electrolyzing water stored in an outer tub 2 is attached to an outer peripheral surface wall 21 of the outer tub 2. The water stored in the outer tub 2 flows into an electrolytic tub 62 through an inlet tube 64A and a connection tube 63A, and is electrolyzed by a plurality of electrode plates 61, after which it is returned to the outer tub 2 through a connection tube 63B and an outlet tube 64B. The electrolyzed water contains active oxygen (O2−), hypochlorous acid (HClO), etc. having a sterilizing effect. Accordingly, the detergency is improved.
