초록 ▼

A water pump control system, such as for a boat, including a battery operated main motor-and-pump unit and a backup motor-and-pump unit. A pump turn-on transistor operates a relay to turn on the main motor-and-pump unit when the water level rises to a high level. A touch switch may be used to turn on the pump turn-on transistor independent of the water level. A pump turn-off transistor, which is turned on by the relay, keeps the main motor-and-pump unit on until the water level drops to a low water level. A backup motor-and-pump unit comes on if the main motor-and-pump unit has not come on after the pump turn-on transistor has been turned on.

대표청구항 ▼

At a site having a battery, a water pump control system comprising: a battery-operated main motor-and-pump unit for pumping water out of the site; an electrically conductive high water level probe positioned to be exposed to water at the site at least as high as a predetermined high level; an electrically conductive low water level probe positioned to be exposed to water at the site at least as high as a lower level than said high level; a grounded electrically conductive probe positioned to be exposed to water at the site touching said low water level probe; a normally non-conductive pump turn-on transistor connected between the battery and said high water level probe to be turned on when water at the site touches said high water level probe and to be turned off when the water level at the site drops below said high water level probe; a relay comprising a coil and a set of normally-open contacts which close when the coil is energized, said coil being connected to the battery and to said pump turn-on transistor to be de-energized before said pump turn-on transistor turns on and to be energized when said pump turn-on transistor turns on, said contacts being connected between the battery and said main motor-and-pump unit to turn on said main motor-and-pump unit when said contacts close; and a normally non-conductive pump turn-off transistor connected to the battery through said relay contacts and connected to said low water level probe to be turned on by the closing of said relay contacts and to remain on as long as said relay contacts remain closed and the water at the site touches said low water level probe, said pump turn-off transistor being connected to said relay coil to hold said coil energized independent of said pump turn-on transistor while the water level at the site is dropping from said high water level probe to said low water level probe.
