Abstract
A drying apparatus for domestic machines such as dishwashers, washing machines or the like, having a liquid drying agent, a tank for the liquid drying agent and a rotatable distributor element for distributing the drying agent, and also a drive for the distributor element, wherein provision is made of a tank inlet for the return flow of the drying agent and a tank outlet for the removal of the drying agent, is proposed, said drying apparatus being improved in terms of leakage safety compared with the prior art. This is achieved according to the invention in that at least one closure element for closing the tank inlet and/or the tank outlet in a liquid-tight manner is provided.
Claims20
In a drying apparatus for domestic machines having a liquid drying agent, a tank for the liquid drying agent and a rotatable distributor element for distributing the drying agent, and a drive for the distributor element, wherein provision is made for a tank inlet for the return flow of the drying agent and a tank outlet for the removal of the drying agent wherein the improvement comprises at least one closure element seal connected to a ram moveable in the axial direction for selectively closing the tank inlet and/or the tank outlet in a liquid-tight manner.
A closure device for a drying apparatus having a hygroscopic drying agent comprising:
- (a) a hygroscopic drying agent tank having an inlet and an outlet in an elevational spaced relationship;
- (b) an impeller to move the hygroscopic liquid between the outlet, an appliance and the inlet, said impeller pump having a movable cam control element connected to a ram moveable in the axial direction to selectively engage the inlet and outlet in the elevational spaced relationship of the inlet and the outlet;
- and
- (c) a closure element operatively connected to the ram and moveable in the axial direction having a first closure device disposed in a first axial position to close the inlet and a second closure device disposed in a second axial position to close the outlet.
A drying apparatus comprising:
- (a) a tank for containing a drying agent, said tank having an inlet and an outlet;
- (b) a rotatable distributor element for removing the drying agent from the outlet of the tank and returning the drying agent to the inlet of the tank, said rotatable distributor element moveable in the axial direction with respect to the tank;
- (c) a closure element connected to the rotatable distributor element and moveable in the axial direction with respect to the tank, said closure element having a first seal for the inlet of the tank disposed in one position along the length of the closure element and a second seal disposed in a second position for the outlet of the tank along the length of the closure element;
- and
- (d) a control element to axially move the closure element between at least two positions to open the inlet and outlet or to close the inlet and outlet depending upon the speed of the rotatable distributor element.
