Definitions

  • the invention relates to a swimming pool skimmer assembly, and more specifically, to a pool skimmer assembly which provides for the alternate operation between suction cleaning and skimming. It also relates to a pool weir system for use with the pool skimmer assembly.
  • swimming pools are generally equipped with one or more fixed surface skimmers to remove surface debris, such as leaves, dust and the like.
  • Surface skimmers have a skimmer throat opening in a skimmer throat at the pool water level through which the surface debris is drawn into the skimmer.
  • the skimmer is connected to the suction side of a pool pump such that surface water is drawn into the skimmer when the pump is operated. Debris drawn into the skimmer is caught in a collection basket within the skimmer.
  • a vertically self-adjusting weir door may be provided in the skimmer throat which adjusts itself upwardly and downwardly in correspondence with variations in the water level of the pool.
  • the principal purpose of the weir door is to provide maximum surface flow velocity of the water into the skimmer body which results in more effective and efficient removal of surface debris.
  • a wide variety of pools skimming assemblies have been provided with a vacuum plate which may be placed over the collection basket within the skimmer.
  • the vacuum plate contains a suction opening to which a suction hose can be attached.
  • Suction driven pool cleaning devices are connected to a free end of the suction hose.
  • the suction driven pool cleaning devices may be configured to vacuuming the floor of the pool to remove submerged debris or may be configure to move about the surface of the pool to skim debris before the debris has a chance to sink to the bottom.
  • the suction hose is connected directly to the suction opening of the vacuum plate, the skimmer is disabled while the suction cleaning device is in operation. In order for the skimmer to operate, the suction hose must be disconnected from the suction opening. Disconnection of the suction hose requires inconvenient manually opening the lid of the skimmer to connect and disconnect the suction hose to permit alternate operation of the skimmer and the suction driven pool cleaning device. Consequently, most pool owners prefer to leave cleaning devices in the pool all of the time, either with the skimmer weir door jammed open or removed to maintain a better hose connection to the vacuum plate, or with the skimmer lid removed.
  • the skimmer With the suction hose permanently connected to the vacuum plate, the skimmer is rendered totally ineffective. Foreign bodies that gather on the water surface are therefore not skimmed off and are allowed to become waterlogged, sink to the bottom of the pool and consume excessive amounts of chlorine. Chlorine is consumed via a neutralisation by oxidation process that occurs on the floor of the pool. Permanently attaching a cleaning device to the skimmer is also not the correct configuration for effective function of a swimming pool circulation system.
  • the top 150mm layer of water is the warmest, where the most microbial activity occurs and where the least free chlorine resides. Skimming of this top layer is the most effective means of removing microbes and reducing chlorine demand.
  • the pool skimmer assembly of Frentzel described above has disadvantages, inconveniences and potential safety risks (especially for children) due to the necessity to remove the skimmer lid to connect a suction cleaner hose.
  • the valve also has many closely-toleranced moving parts, some of which are made of metal and are relatively expensive to manufacture.
  • the valve is complex in operation, including biasing means in the form of a coiled spring and a number of spaced slots in a piston.
  • the piston rotates in operation and this can cause twisting of the spring, preventing further rotational movement of the piston as unwanted torque develops in the piston. If the piston does not rotate sufficiently between pump cycles then the valve is rendered inoperative as the valve will continuously operate in one of its two operating positions.
  • the valve requires a specific pressure differential for effective operation. Further, the round-shaped skimmer opening can create a vortex that can produce a noticeable noise which can be heard from a reasonable distance.
  • Frentzel also discloses a height adjustable pipe of the pool skimmer assembly to which the suction hose is connected.
  • the pipe is adjustable so that the suction hose may be wedged against an upper surface of the skimmer throat. This is inconvenient as the hose is lifted out of the water in which it is usually supported.
  • the hose including the weight of the water being pumped in the section of the hose above the water imparts unnecessary large axial forces on the weir door and bending moments on the pipe to which it connects.
  • the invention resides in a pool skimmer assembly fluidly connected to a pool pump, the pool skimmer assembly including:
  • a first first vacuum plate having a skimmer opening therein through which pool water can be sucked from below the first vacuum plate when the pool pump operates in suction;
  • valve member which is hingedly connected relative to the first vacuum plate, the valve member being hingedly displaceable between a closed position wherein the valve member closes off the skimmer opening in a hose suction mode of the skimmer assembly and an open position wherein the valve member is spaced from the skimmer opening in a skimmer mode of the skimmer assembly;
  • a cooperating cam and follower one of the cam or follower forming part of the first vacuum plate and the other forming part of the valve member, the cam configured to alternate the valve member between the closed position and an open position for each cycle the pool pump operates in suction.
  • the first vacuum plate includes a hose suction opening through which pool water may be sucked when the first valve member is in the closed position.
  • a suction driven pool cleaning device is preferably fluidly connected to the hose suction opening by a hose.
  • the first valve member is positively buoyant.

  • first valve member is positively buoyant so that it is urged away from the skimmer opening when there is no suction below the first vacuum plate.
  • the first valve member preferably includes a float which makes it positively buoyant.
  • the skimmer assembly has a cooperating cam and follower, one of the cam or follower forming part of the first vacuum plate and the other forming part of the first valve member, the cam configured to cycle the first valve member between the closed position and open position as the valve is hingedly displaced during successive suction operation of the pool pump.
  • the follower is resiliency displaceable relative to the cam.
  • the pool skimmer assemblies are configured so that suction through the skimmer opening when the pool pump operates in suction urges the first valve member towards the skimmer opening, and the positive buoyancy of the first valve member urges the first valve member away from the skimmer opening when the pool pump does not operate and there is no suction through the skimmer opening.

These modes are the hose suction mode when the first flap 14 is in the closed position (FIG 6) and the skimmer mode when the flap is in the open position (FIG 8). In between the modes the first flap 14 floats in either the first float position or the second float position.
