The present invention proposes a washing machine having a simple-structured mechanism for correcting the balance of the drum. In an embodiment of the present invention, plural water-holding chambers are located at the back of the drum around the rotation axis. The water-holding chamber has an opening for introducing water from a water discharge port . At the start of an extracting operation, all the water-holding chambers are emptied by rotating the drum at low speed. After that, when the eccentric load due to an uneven distribution of the laundry is greater than an upper limit value, the drum is rotated at a preset speed and a water supply valve is opened. Thus, the water from the water discharge port is supplied into all the water-holding chambers, and the water is held in the water-holding chamber by the centrifugal force. After that, the speed of the drum is temporarily reduced at a time point corresponding to the position of the eccentric load, whereby a part of the water held by one or some of the water-holding chambers at or close to the position of the eccentric load is let to spill out from the chamber. After thus canceling the load unbalance of the drum around the rotation axis as a whole, the drum is rotated at high speed for extraction.

Washing machine

A remote management system where a central control apparatus for controlling machines installed in plural stores from remote on receiving data of working conditions of the machines, which is transmitted from terminals of the stores, for displaying a layout of the machines in each store, a machine kind, a layout of the store such as a wall, an entrance and a window on blocks, for example, by a coloring, a hatching of the block, on and off of the display of the block and the like.

Remote management system

A remote management system where data detected by a sensor for detecting a condition of a machine is input from an input port of an interface unit of a control unit such as a microcomputer, and the interface unit is connected via a data transmission controller over a communication line with a central control apparatus which manages a machine like a washing machine from remote, and further the detected data is transmitted from the interface unit to the central control apparatus though the control unit is inapplicable to communication, while the interface unit passes the detected data of the sensor without processing and outputs the detected data to the control unit by means of setting the state of an output port thereof same as that of the input port.
