Surge fill apparatus and method for top load washing machine
A surge fill apparatus and method for a top load washing machine is disclosed. A top load washing machine includes a cabinet, a tub positioned within the cabinet, and a basket for receiving a wash load rotatably supported within the tub. The washing machine further includes a reservoir in fluid communication with the tub. The reservoir has the capacity to store a volume of wash fluid. The reservoir releases the volume of wash fluid into basket when the volume of wash fluid in the reservoir reaches a threshold level. In this manner, the apparatus and method of the present disclosure provides for a surge of wash fluid to be provided to the top portion of a wash load such that the top portion of the wash load can be cleaned and rinsed more efficiently.
1. A washing machine, comprising:
a cabinet;
a tub positioned within the cabinet;
a basket rotatably supported within said tub; and
a reservoir in fluid communication with said basket, said reservoir having the capacity to store a volume of wash fluid;
a sensor configured to monitor the volume of wash fluid in said reservoir; and
a controller;
wherein said controller is configured to control the release of wash fluid from said reservoir into said basket when the volume of wash fluid in said reservoir reaches a threshold level such that the flow rate at which the volume of wash fluid is released from said reservoir into said basket is greater than a flow rate provided by a wash fluid source separate from the reservoir used to provide wash fluid into said basket.
2. The washing machine of claim 1 , wherein the volume of wash fluid is released from said reservoir to said basket through a siphon, a spray outlet, or a mechanical valve.
3. The washing machine of claim 1 , wherein, the controller is configured to control a control valve to release the volume of wash fluid from the reservoir into said basket when the volume of wash fluid in said reservoir reaches a threshold level.
4. The washing machine of claim 1 , wherein said basket receives a wash load, said reservoir releasing the volume of wash fluid onto the top of said wash load when the volume of wash fluid in said reservoir reaches the threshold level.
5. The washing machine of claim 1 , wherein said reservoir is disposed above said tub.
6. The washing machine of claim 1 , wherein said reservoir is in fluid communication with an outside wash fluid source.
7. The washing machine of claim 1 , wherein said reservoir is in fluid communication with a recirculation line and a pump, said pump providing wash fluid from said tub to said recirculation line.
8. The washing machine of claim 7 , wherein said recirculation line further comprises a diverter valve, said diverter valve operable to direct wash fluid from said recirculation line to said reservoir or to direct wash fluid from said recirculation line to said tub.
