Method for relieving suction force in a pool drain
View Patent ↗Methods of relieving the suction force in a swimming pool or spa. A first method may include the steps of closing an aperture in a hydraulic suction fuse through magnetic force and opening the aperture by increasing suction force within the hydraulic suction fuse. Implementations of hydraulic suction fuses may also utilize a method of adjusting the fuse point of a hydraulic suction fuse. The method may include decoupling a magnet assembly from a first step having a first height, the first step contained in a fuse body contained in the hydraulic suction fuse. The method may also include rotating the magnet assembly and coupling the magnet assembly with a second step having a second height, the second step contained in the fuse body.
1. A method for relieving the suction force of a drain in a swimming pool or spa using a hydraulic suction fuse having a permanent, non-electric magnet, the method comprising:
setting a hydraulic suction fuse;
opening the hydraulic suction fuse by increasing suction force within the hydraulic suction fuse and by overcoming a magnetic force from the permanent, non-electric magnet within the hydraulic suction fuse;
resetting the hydraulic suction fuse through magnetic force from the permanent, non-electric magnet.
2. The method of claim 1 , wherein the resetting of the hydraulic suction fuse comprises automatically resetting the hydraulic suction fuse through the magnetic force when the suction force is decreased within the hydraulic suction fuse.
3. The method of claim 2 , wherein the automatically resetting the hydraulic suction fuse comprises:
automatically closing an aperture in the hydraulic suction fuse through the magnetic force.
4. The method of claim 1 , wherein the resetting of the hydraulic suction fuse comprises manually resetting the hydraulic suction fuse.
5. The method of claim 1 , wherein setting the hydraulic suction fuse comprises:
determining whether to increase or decrease a fuse point of the hydraulic suction fuse; and
adjusting a distance between a magnet assembly introducing the magnetic force and an attractor portion to adjust the fuse point.
6. The method of claim 5 , wherein adjusting the distance between the magnet assembly and the attractor portion comprises:
decoupling the magnet assembly from a first step in a fuse body of the hydraulic suction fuse, the first step comprising a first height; and
coupling the magnet assembly with a second step in the fuse body, the second step comprising a second height different from the first height.
7. The method of claim 5 , wherein adjusting the distance between the magnet assembly and the attractor portion comprises rotating the magnet assembly.
8. The method of claim 5 , further comprising coupling the magnet assembly with the first step and the second step through a pin.
9. The method of claim 1 , wherein opening the hydraulic suction fuse comprises opening an aperture in the hydraulic suction fuse.
10. The method of claim 9 , wherein resetting the hydraulic suction fuse comprises closing the aperture in the hydraulic suction fuse.
11. The method of claim 1 , wherein opening the hydraulic suction fuse further comprises drawing air into the hydraulic suction fuse.
12. The method of claim 1 , wherein opening the hydraulic suction fuse further comprises causing ambient fluid from outside the hydraulic suction fuse to flow through the hydraulic suction fuse and into a pump inlet coupled to the drain.
13. The method of claim 1 , further comprising submerging the hydraulic suction fuse in water prior to opening the hydraulic suction fuse.
14. A method for relieving the suction force of a drain in a swimming pool or spa using a hydraulic suction fuse having a permanent, non-electric magnet, the method comprising:
submerging a hydraulic suction fuse in water below a water level of the swimming pool or spa;
setting the hydraulic suction fuse through magnetic force attracting a permanent, non-electric magnet to an attractor;
opening the hydraulic suction fuse and causing ambient fluid from outside the hydraulic suction fuse to flow through the hydraulic suction fuse and into a pump inlet coupled to the drain by increasing suction force within the hydraulic suction fuse and by overcoming the magnetic force from the permanent, non-electric magnet;
resetting the hydraulic suction fuse through the magnetic force from the permanent, non-electric magnet.
15. The method of claim 14 , wherein the resetting of the hydraulic suction fuse comprises automatically resetting the hydraulic suction fuse when the suction force is decreased within the hydraulic suction fuse.
16. The method of claim 14 , wherein setting the hydraulic suction fuse comprises:
determining whether to increase or decrease a fuse point of the hydraulic suction fuse; and
adjusting a distance between the permanent, non-electric magnet and an attractor portion in accordance with the determination.
17. The method of claim 16 , wherein adjusting the distance between the permanent, non-electric magnet and the attractor portion comprises:
decoupling the permanent, non-electric magnet from a first step in a fuse body of the hydraulic suction fuse, the first step comprising a first height; and
coupling the permanent, non-electric magnet with a second step in the fuse body, the second step comprising a second height different from the first height.
18. The method of claim 16 , wherein adjusting the distance between the permanent, non-electric magnet and the attractor portion comprises rotating the permanent, non-electric magnet.
