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.
