An engaging groove partis provided at the outer circumferential edge of a rotorof an outer-rotor type motor directly connected to the main shaftof a drum, and on the other hand, a drum locking deviceis provided directly below the shaft. The drum locking deviceis constructed so that a lock pin moves up and down in response to rotation of a torque motor, and when the lock pin advances and fits into the groove of the engaging groove pan, the position of the drumis fixed. Thereby, the stopping position of the drum can be fixed with a simple construction.

Drum washing machine

In a drum type washing machine, a drumis mounted to rotate about a horizontal axis extending in the lateral direction in a tubA tub openingwith a tub dooris formed in the tubunder the throw-in openingformed in the front part of the top of the housing. A drum openingwith a drum door composed of a double door opening frontward and backward is formed in the peripheral wall of the drumThe drumis stopped so that the drum openingcoincides with the tub opening. The drum door, forced into its opening direction, is held in a closed position by an engagement of a clawand an engagement holeWhen a user rotates a operation leverfor latching or unlatching the tub doorthe drum door open/close mechanismfunctions to make two rodsandproject or withdraw, whereby the drum dooris brought into an engaged or unengaged state. By this mechanism, the drum dooropens or closes with the opening or closing operation of the tub door. Thus, the operation of the doors is simplified, and the laundry loaded into or unloaded out of the drumby fewer working steps.

Drum type washing machine

There is disclosed a washing/drying machine having a purpose of shortening a time required for a washing operation and improving an operation efficiency, and comprising: an inner drum in which things to be washed are accommodated and in which a washing operation of the things to be washed and a drying operation after end of the washing operation are performed; a water supply passage for supplying water into the inner drum and a drainage passage for discharging the water from the inner drum in the washing operation; a refrigerant circuit in which a compressor, a gas cooler, an expansion valve, an evaporator and the like are successively connected to one another in an annular form via a piping and in which carbon dioxide is used as a refrigerant; and a blower for blowing air which has exchanged heat with the gas cooler into the inner drum to allow the air passed through the inner drum to exchange the heat with the evaporator in the drying operation.

Washing/drying machine

A washing/drying machine has objects to shorten a time required for a washing operation, to improve a heat exchange capability in a radiator and an evaporator, and to shorten a drying time for things to be dried, and comprises: an accommodating chamber in which things to be washed (things to be dried) are accommodated and in which a drying operation of the things to be washed is performed; a refrigerant circuit in which a compressor, a gas cooler, a decompression device, an evaporator and the like are successively connected to one another in an annular form via a piping and in which carbon dioxide is used as a refrigerant and which has a supercritical pressure on a high pressure side thereof; and blower means for blowing air which has exchanged heat with the radiator into the accommodating chamber to allow the air passed through the accommodating chamber to exchange the heat with the evaporator, wherein the blower means constitutes a circulation direction of the air passed through the gas cooler, and that of the refrigerant flowing in the gas cooler in such a manner as to form a counter-flow, and constitutes a circulation direction of the air passed through the evaporator, and that of the refrigerant flowing in the evaporator in such a manner as to form a counter-flow.

Drying machine

A washing machine comprises a tub, in which a pulsator is rotatably arranged. The pulsator is driven by a motor positively or reversely. When a start switch is pressed, first an initial cycle is started for a relatively short period of time to dissolve detergents. When this initial cycle is completed, a main cycle is started, during which the pulsator repeats positive and reverse rotations with intervals. The main cycle is arranged to continue for a set period of time, into which auxiliary cycles shorter than the main cycle are intermittently inserted. The positively and reversely rotating times of the adjoining repeating units included in the main cycle differ with each other. In the auxiliary cycle, its repeating unit involves a relatively longer rotating time or a shorter recess time of the pulsator as compared with the repeating unit constituting the main cycle. Accordingly, during the auxiliary cycle, a water current stronger than that in the main cycle is produced, thus restraining the 'entangling clothes' during a washing process.
