  • Patent number: 10508383
    Abstract: Disclosed is disclosure clothing treatment device capable of effectively preventing odour from reabsorbing to clothing. A clothing deodorizing device includes: a bag body for accommodating clothing; an ozone supply apparatus including an ozone generator and a blowing fan wherein the air supply fan operates to deliver the ozone generated by the ozone generator into the bag body by virtue of the flow of the air; and a control part for controlling operation of the ozone generator and the blowing fan. After performing deodorization operation that enables the ozone generator and the blowing fan to operate, the control part performs reabsorption preventing operation that enables the blowing fan to operate intermittently.

  • Publication number: 20180298538
    Abstract: A washing machine is provided. The washing machine includes: a washing tub having an axis extending longitudinally; a circulation path configured to draw detergent solution mixed with a detergent in the washing tub and return the detergent solution into the washing tub from an upper side; a pump configured to pump the detergent solution in the washing tub into the circulation path and allow the detergent solution to rise in the circulation path; and a controller configured to execute a washing operation. The washing operation includes a circulation-soaking process during which a circulation process and a soaking process are conducted alternately and repeatedly. The detergent solution is circulated between the washing tub and the circulation path by driving the pump and sprayed onto washings in the circulation process. The pump is stopped from being driven and, the washings are soaked with the detergent solution in the washing tub in the soaking process.

  • Publication number: 20180135232
    Abstract: The present disclosure provides a clothes treating device comprising: a bag body for accommodating clothes; an ozone supply device including an ozone generator and a blowing fan, wherein ozone generated by the ozone generator is delivered into the bag body through flow of air by means of operation of the blowing fan; and a control part. The control part can change an output voltage value output to the blowing fan in a manner of enabling the blowing fan to keep specified rotating speed, and obtain the output voltage value when controlling the blowing fan to keep the specified rotating speed and a value of driving current flowing to the blowing fan, and stop the ozone generator under a condition of judging that the obtained values are respectively less than a first threshold and a second threshold.

  • 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.
