Abstract

A top load drum washing machine and a positioning device, which relate to laundry washing equipment and which solve problems in the existing technology where a belt is easily worn out by the edge of a groove, which is located on a pulley and which corresponds to a latch bolt of a drum locking device, and where the positional arrangement of the locking device is not flexible enough. For this purpose, the positioning device for use with a top load drum washing machine includes a locking position which is provided on a spoke of a pulley; a locking device which is provided on an outer cylinder, the locking device being provided with a latch bolt; the position of the locking device corresponds to the rotational path of the locking position such that the latch bolt may form a locking fit with the locking position when a drum stops rotating.

Claims

exact text as granted — not AI-modified
1 - 9 . (canceled) 
     
     
         10 . A positioning device for a top load drum washing machine, the washing machine comprising an outer cylinder, an inner cylinder disposed inside the outer cylinder and a pulley connected to the inner cylinder; the positioning device comprising:
 a locking structure disposed on one spoke of the pulley; and   a locking device disposed on the outer cylinder, the locking device comprising a lock body and a locking tongue;   wherein a position of the locking device corresponds to a rotational path of the locking structure so that when the inner cylinder stops rotating, the locking tongue forms a locking engagement with the locking structure.   
     
     
         11 . The positioning device for a top load drum washing machine according to  claim 10 , wherein the locking structure is a groove disposed on the spoke. 
     
     
         12 . The positioning device for a top load drum washing machine according to  claim 11 , wherein the locking tongue is a rocker type locking tongue, one end of which is connected to the lock body. 
     
     
         13 . The positioning device for a top load drum washing machine according to  claim 10 , wherein the positioning device further comprises a detecting device configured to detect a rotational position of the inner cylinder. 
     
     
         14 . The positioning device for a top load drum washing machine according to  claim 13 , wherein the detecting device comprises a signal transmitting device and a signal receiving device, the signal transmitting device is disposed on the pulley, and the signal receiving device is disposed on the outer cylinder or on a body of the washing machine. 
     
     
         15 . The positioning device for a top load drum washing machine according to  claim 14 , wherein the signal transmitting device is disposed on a rim of the pulley. 
     
     
         16 . The positioning device for a top load drum washing machine according to  claim 13 , wherein the detecting device comprises a signal transmitting device and a signal receiving device, the signal transmitting device is disposed on the outer cylinder or a body of the washing machine, and the signal receiving device is disposed on the pulley. 
     
     
         17 . The positioning device for a top load drum washing machine according to  claim 14 , wherein the signal transmitting device is a magnet, and the signal receiving device is a Hall element. 
     
     
         18 . A top load drum washing machine, comprising the positioning device according to  claim 10 .
