Float Switch of Washing Machine

Abstract

In general, the washing machine washes laundry through washing, rinsing, and spinning cycles to remove soil stuck to clothes, beddings, and so on held in a drum ( 70 ) by using action of water supplied to the tub ( 60 ) in the washing machine, and detergent. To achieve above object, in one aspect of the present invention, a float switch ( 100 ) in a washing machine includes a switch body ( 102 ) forming an exterior of the float switch ( 100 ), a float ( 108 ) in the switch body ( 102 ) for moving up/down by washing water, a sensor ( 110 ) for sensing a position of the float ( 108 ), and a water protector ( 120 ) for preventing the washing water from infiltrating to the sensor ( 110 ). The water protector ( 120 ) is a “ ” shape bracket over an upper surface of the switch body ( 102 ).

1 . A float switch in a washing machine comprising: 
 a switch body forming an exterior of the float switch;    a float in the switch body for moving up/down by washing water;    a sensor for sensing a position of the float; and    a water protector for preventing the washing water from infiltrating to the sensor.    
   
   
       2 . The float switch as claimed in  claim 1 , wherein the water protector is a “ ” shaped bracket over an upper surface of the switch body.  
   
   
       3 . A float switch in a washing machine comprising: 
 a switch body divided into two sides, having a floating portion for rising up of leaked washing water, and a sensor space for mounting a sensor for sensing a level of the washing water in the floating portion, both formed therein;    a float in the floating portion for floating on a surface of the washing water;    a sensor in the sensor space for measuring a height of the float; and    a water protector for preventing the washing water from infiltrating into the sensor space.    
   
   
       4 . The float switch as claimed in  claim 3 , wherein the water protector is a bracket at one of the divided two sides of the switch body over the sensor space to cover a joining surface of the divided two sides of the switch body from over the joining surface.  
   
   
       5 . The float switch as claimed in  claim 4 , wherein the bracket has a “ ” shape.  
   
   
       6 . The float switch as claimed in  claim 3 , wherein the floating portion has openings in a side surface for flowing in of the washing water.  
   
   
       7 . The float switch as claimed in  claim 3 , further comprising a soft member connected between one sides of the switch body divided into two sides.  
   
   
       8 . The float switch as claimed in  claim 3 , further comprising at least one fastening means for fastening the switch body.  
   
   
       9 . The float switch as claimed in  claim 3 , wherein the fastening means includes; 
 a hook at one of sides of the switch body divided into two sides, and    a hook hole opposite to the hook for receiving and holding the hook.    
   
   
       10 . The float switch as claimed in  claim 8 , wherein at least one of the fastening means is formed over the sensor space.  
   
   
       11 . A float switch in a washing machine comprising: 
 a switch body divided into two sides, having a floating portion for rising up of leaked washing water, and a sensor space for mounting a sensor for sensing a level of the washing water in the floating portion, both formed therein;    a float in the floating portion for floating on a surface of the washing water; and    a sensor in the sensor space for measuring a height of the float,    wherein one of the two sides of the switch body includes a portion over the sensor space extended to cover a portion of the other side of the switch body over the sensor space.    
   
   
       12 . The float switch as claimed in  claim 11 , further comprising a soft member connected between one sides of the switch body divided into two sides.  
   
   
       13 . The float switch as claimed in  claim 11 , further comprising at least one fastening means for fastening the switch body.  
   
   
       14 . The float switch as claimed in  claim 13 , wherein the fastening means includes; 
 a hook at one of sides of the switch body divided into two sides, and    a hook hole opposite to the hook for receiving and holding the hook.    
   
   
       15 . The float switch as claimed in  claim 13 , wherein at least one of the fastening means is formed over the sensor space.
