Gurgling sink when washer drier runs

Any suggestions as to what I can do with a kitchen sink which gurgles when the drier component of the washer drier is on? No septic tank (at least not in my property) so assume its off mains drainage. The machine is right beside the kitchen sink. No smells or problems with the drain flow or gurgling when using the sink or any other sinks/toilets in the house. Is there some sort of liquid I can put down the drains that might improve the condition of the pipes assuming it may be restricted flow causing this?
