Washing machine

Abstract

A washing machine includes an outer tub, and a counterweight fastened to the outer tub by a screwed connection. The screwed connection includes a screw guided through an opening of the counterweight, a spiked plate at an end of the screw with a spike-type projection in a fastening section of the outer tub that non-rotatably secures the spiked plate, and a brace at the other end of the screw that braces the counterweight and the fastening section with the spiked plate.

         18 . A washing machine comprising:
 an outer tub; and   a counterweight fastened to the outer tub by a screwed connection comprising:
 a screw guided through an opening of the counterweight, 
 a spiked plate at an end of the screw with a spike-type projection in a fastening section of the outer tub that non-rotatably secures the spiked plate, and 
 a brace at the other end of the screw that braces the counterweight and the fastening section with the spiked plate. 
   
     
     
         19 . The washing machine of  claim 18 , wherein the spiked plate comprises a spiked nut which can be screwed with the screw. 
     
     
         20 . The washing machine of  claim 18 , wherein the spiked plate comprises a screw head of the screw. 
     
     
         21 . The washing machine of  claim 18 , wherein the spiked plate comprises a washer associated with a screw head of the screw element, by means of which washer the screw head can be non-rotatably connected. 
     
     
         22 . The washing machine of  claim 18 , wherein the spike-type projection has a rounded spike tip. 
     
     
         23 . The washing machine of  claim 18 , wherein the spiked plate has a polygonal peripheral profile with an even number of edges. 
     
     
         24 . The washing machine of  claim 18 , wherein the spiked plate has a pair of parallel lateral surfaces. 
     
     
         25 . The washing machine of  claim 18 , further comprising a rotation stop on the fastening section associated with the spiked plate, which rotation stop forms an additional rotation prevention for the spiked plate. 
     
     
         26 . The washing machine of  claim 25 , wherein the rotation stop on the fastening section has two opposing side walls, parallel with one another, between which the spiked plate is non-rotatably arranged. 
     
     
         27 . The washing machine of  claim 18 , wherein the spiked plate comprises an inner screw fastening section and an outer plate-shaped abutment section abutting against the fastening section, and wherein the spike-type projection is on the outer plate-shaped abutment section. 
     
     
         28 . The washing machine of  claim 27 , wherein the spiked plate further comprises a plate-type spring section is between the inner screw fastening section and the outer plate-shaped abutment section. 
     
     
         29 . The washing machine of  claim 27 , wherein the spiked plate comprises a spiked nut and a receiving thread for the screw in the inner screw fastening section. 
     
     
         30 . The washing machine of  claim 27 , wherein the spiked plate comprises a screw head, and wherein the inner screw fastening section is non-rotatably connected to the screw. 
     
     
         31 . The washing machine of  claim 30 , wherein the inner screw fastening section is integrally non-rotatably connected to the screw. 
     
     
         32 . The washing machine of  claim 18 , wherein the outer-tub fastening section has a laterally open insertion slot through which the screw projects. 
     
     
         33 . The washing machine as claimed in  claim 32 , wherein the fastening section forms a guide channel into which the insertion slot opens and extends in a longitudinal direction, and wherein the spike plate is displaceable along the guide channel and the screw is displaceable along the insertion slot to a defined fastening position. 
     
     
         34 . The washing machine of  claim 18 , wherein the fastening section comprises the same material and forms one piece with the outer tub. 
     
     
         35 . The washing machine of  claim 18 , wherein the outer tub and/or the fastening section comprise plastic.
