Antonio Conte's team are now 11 points clear at the top of the Premier League table and will maintain at least a 10-point lead by the end of the weekend as Manchester City do not play.
Cesc Fabregas, Pedro and Diego Costa scored for the Blues to extend their winning run on home turf, which now stretches back to the 3-0 triumph over Leicester City on October 15.
The last time Chelsea dropped points at the Bridge came a month earlier, when they were defeated 2-1 by Liverpool.
Since switching to a 3-4-3 formation and equalling the record of 13 consecutive Premier League wins in a single season, Conte's men have only dropped points away from home.
Chelsea are currently on pace to achieve 92 points this season, which would be the joint-second highest total in Premier League history after Jose Mourinho's 2004-05 Blues team, who amassed 95 points.
