Drum type washing machine

Abstract

A drum type washing machine is disclosed. The drum type washing machine includes a tub for holding wash water; a bearing housing laid in a rear wall of the tub, the bearing housing having a fastening groove part having a stator of a motor fastened thereto; and a contact-proof-part for preventing the fastening groove part of the bearing housing and a stator fastening part from being directly contacted with each other. An object of the present invention is to provide a drum type washing machine which can reduce noise generated by collision between a fastening groove part of a bearing housing and a stator fastening part by means of an improved structure of a tub.

       5 . The drum type washing machine of  1 , wherein the stator is assembled as a fastening member is fastened to the fastening groove part of the bearing housing through the stator fastening part.  
   
   
       6 . The drum type washing machine of  1 , wherein a female thread is formed in the fasten groove part of the bearing housing for allowing the fastening member fastened thereto.  
   
   
       7 . The drum type washing machine of  5 , wherein the fastening member is a fastening screw fastened to the fastening groove part of the bearing housing with forming the female thread itself.  
   
   
       8 . The drum type washing machine of  1 , wherein the tub and the contact-proof-part are made of resin and the bearing housing is made of aluminum.  
   
   
       9 . The drum type washing machine of  1 , further comprising a metal mold guide part provided in the fastening groove part for allowing the contact-proof-part injection-molded smoothly.  
   
   
       10 . The drum type washing machine of  1 , wherein the metal mold guide part is a guide groove formed at the circumferential end of the fastening groove part.  
   
   
       11 . A drum type washing machine comprising: 
 a tub for holding wash water;    a bearing housing provided in a rear wall of the tub, the bearing housing having a fastening groove part having a stator of a motor fastened thereto;    a molding part injection-molded in the rear wall of the tub for laying the bearing housing therein; and    a contact-proof-part for preventing the fastening groove part of the bearing housing and a stator fastening part from being directly contacted with each other.    
   
   
       12 . The drum type washing machine of  claim 11 , wherein the contact-proof-part is provided between a circumferential end of the fastening groove part and the stator fastening part of the stator.  
   
   
       13 . The drum type washing machine of  claim 11 , wherein the contact-proof-part is formed in a shape which covers the circumferential end of the fastening groove part and an inner circumferential surface of the fastening groove part.  
   
   
       14 . The drum type washing machine of  claim 11 , wherein the contact-proof-part is formed as one body with the molding part.  
   
   
       15 . The drum type washing machine of  claim 11 , wherein the stator is assembled as a fastening member is fastened to the fastening groove part of the bearing housing through the stator fastening part.  
   
   
       16 . The drum type washing machine of  claim 11 , wherein a female thread is formed in the fastening groove part of the bearing housing for allowing the fastening member fastened thereto.  
   
   
       17 . The drum type washing machine of  claim 15 , wherein the fastening member is a fastening screw fastened to the fastening groove part of the bearing housing with forming the female thread.  
   
   
       18 . The drum type washing machine of  claim 1 , wherein the tub, the molding part and the contact-proof-part are made of resin and the bearing housing is made of aluminum.  
   
   
       19 . The drum type washing machine of  claim 11 , further comprising a metal mold guide part provided in the fastening groove part for allowing the molding part and the contact-proof-part injection-molded smoothly.  
   
   
       20 . The drum type washing machine of  claim 19 , wherein the metal mold guide part is a guide groove formed at the circumferential end of the fastening groove part.
