Definitions

  • This invention is in the field of swimming pool cleaning vehicles, and more particularly the invention relates to improvement on its bottom design for preventing the swimming pool cleaning vehicle from becoming stuck or hung as it runs along the floor of the swimming pool from various floor obstacles.
  • FIG. 1 Prior art construction is illustrated in Fig. 1 which consists of the following: an exterior body (100) which forms a hollow interior (110), at least one intake port (120) located on the said body (100); at least one filter bag (130) filtering water receiving from intake port (120).
  • the filter bag is located inside the hollow interior (110) of the body (100); at least one outlet port (140) located on the body(100) and at least one water pump (150) placed under the said water outlet port (140) for pumping water out from the body (100), creating the partial vacuum and water flow inside the body (100) required in order to pull up dirt and debris at swimming pool floor, ensure water with debris could enter the body (100) through the intake port (120), a filter bag (130) which secured by the inside edge of intake port (120), filtering the dirt and debris and clean the swimming pool water.
  • wheel and/or roller (160) placed at the corresponding body (100) bottom, this wheel and/or roller (160) is driven by motor inside/outside the body (100) or jet propelled, moving the unit around in a swimming pool.
  • Fig 1 existing swimming pool cleaner bottoms are flat.
  • the bottom has at least one intake port. Since swimming pool cleaner has to suck water in through this intake port, intake port cannot have floor clearance too high. If it is too high, debris set at swimming pool floor cannot be picked up by the limited partial vacuum and water flow generated by the water pump. If it is too low, as illustrated in Fig. 2 which has the main drain on certain type of swimming pools, or naturally formed uneven obstacles. For example, a layer up to 2" thick sand is laid under PVC film liner for water proof purpose when a new swimming pool is constructed. After this type of swimming pool is used in a period of time, will have foot prints of different sizes by swimming pool users. That makes the swimming pool floor naturally uneven causing swimming pool cleaner stuck and cannot run normally or extra drive motor wear caused by slippage, prevents the swimming pool cleaner operate normally, even running the risk of being hit and damaged, causing higher defective rate and higher maintenance cost.
  • a skirt (300) By adding a skirt (300) at the intake port, stir up the segregated dirt when the swimming pool cleaner moves.
  • the skirt (300) can be made of elastic material or make a hinge such as elastic axle between the skirt (300) and intake port, enable the skirt (300) swings when it meets dirt segregated and stir it up without affecting swimming pool cleaner motion. It is actually lower the effective floor clearance at the intake port. If the skirt (300) is lowered too far will only push dirt segregated around and therefore segregated dirt cannot be sucked up into the swimming pool cleaner body. Besides, such a skirt could be caught by uneven swimming pool floor. The skirt cannot remain closed or the cleaner cannot pass dirt through it to be sucked into the swimming pool cleaner body. On the other hand, a non-closed skirt cannot limit the water flow and therefore cannot generate enough partial vacuum and flow rate to bring debris and segregated dirt up.
  • Purpose of this invention is to make a swimming pool cleaner that can overcome obstacles when it runs in a swimming pool, operate normally but will not affect the partial vacuum and water flow required at water inlet port.
  • this invention proposes a swimming pool cleaner consists of:
  • the body shell has symmetric concave inwards bottom.
  • the body shell bottom has a number of wheel or roller. Either between front roller and rear wheel of said body shell bottom, or between front wheel and rear roller of said body shell bottom is a front to back symmetric concave inwards.
  • said body shell has asymmetric concave inwards bottom.
  • said body shell bottom has a number of wheel or roller. Either between front roller and rear wheel of said body shell bottom, or between front wheel and rear roller of said body shell bottom is a front to back asymmetric concave inwards
  • said body shell bottom is significantly concave inwards.
  • said water inlet port facing downwards, or said water inlet port close to wheel or roller.
  • said water inlet port is located at the bottom and close to wheel and/or roller location.
  • said water inlet port is located at the bottom and located at wheel and/or roller front, back or right under it.
  • This invention provides a swimming pool cleaner with concave inwards bottom that can overcome obstacles when it runs in a swimming pool, operate normally but will not affect the partial vacuum and water flow required at water inlet port, reduce the swimming pool cleaner defective rate and maintenance cost, improve the operating efficiency. Furthermore, by locating the water intake port at appropriate location such as close to wheel and/or roller can ensure water with dirt and debris be sucked into the swimming pool cleaner.
  • this invention is making a swimming pool cleaner with concave inwards bottom to ensure it can easily overcome obstacle. Furthermore, by locating the water intake port at appropriate location such as close to wheel and/or roller can ensure water with dirt and debris be sucked into the swimming pool cleaner.
  • Fig 4 illustrates construction of a swimming pool cleaner described in this invention at first application example, consists of: an outer shell (400), forms a hollow interior (410).
  • One or more water pump (450) placed under the corresponding water outlet port (440), pumps water from outer shell (400) to outside.
  • swimming pool cleaner also consists of certain number of wheel or roller or combination of wheel and roller (460) (this disclosure assign 460 on both wheel and roller), placed at the bottom (480) of the outer shell (400) correspondingly. If only wheels (460) are used, said wheel (460) will be generally 2 pairs, placed at the both ends of bottom(480) of the outer shell(400) correspondingly. It is obvious that 3 pairs or more wheels (460) could be placed at the bottom (480) of the outer shell (400). If only rollers (460) are used, said roller (460) will be generally 2 pieces, placed at the both ends of bottom (480) of the outer shell (400) correspondingly. It is obvious that 3 pieces or more rollers (460) could be placed at the bottom (480) of the outer shell (400).
  • wheel and roller (460) are used at the same time, normally one pair of wheel and 1 piece of roller, placed at the both ends of bottom (480) of the outer shell (400) correspondingly. It is obvious that more wheels and rollers (460) could be placed at the bottom (480) of the outer shell (400). Said wheel and/or roller (460) can be driven by motor placed inside/outside the outer shell (400). Said wheel and/or roller (460) can also be water jet propelled by pressurized water generated by water pump placed inside/outside the outer shell (400). (Not shown in the illustration).
  • outer shell (400) bottom (480) is made to be concave inwards. This allows the swimming pool cleaner easily overcome swimming pool floor obstacles such as main drain cover or steps.
  • Outer shell (400) bottom (480) could be symmetric concave or asymmetric concave.
  • outer shell (400) bottom (480) has either 2 pairs of wheel (460) or 2 pieces of roller (460).
  • Said body shell (400) bottom (480) is a front to back symmetric concave inwards either between front wheel and rear wheel, or between front roller and rear roller.
  • said body shell (400) bottom (480) is a front to back symmetric concave inwards between 2 adjacent wheels or rollers. Furthermore, amount of body shell (400) bottom (480) concave inwards could be increased to accommodate greater swimming pool floor obstacles.
  • water intake port (420) is placed on the outer shell (400) bottom (480) and is close to the wheel and/or roller. That will not affect the required partial vacuum and water flow at the water intake port (420). Dirt and debris could then easily suck up into the swimming pool cleaner.
  • Water intake port (420) described here could points downwards, or water intake port (420) placed close to the wheel and/or roller (460). Number of water intake port (420) could vary according to the cleaning need. It could be one or more.
  • Fig 5 shows the construction of swimming pool cleaner in application example #2.
  • Difference between this application example #2 and application example #1 is the outer shell (400) bottom (480) is asymmetric concave inwards.
  • Its outer shell (400) bottom (480) has a number of wheel and roller (460).
  • Said outer shell (400) bottom (480) is asymmetric concave inwards between front roller and rear wheel, or between front wheel and rear roller. Said asymmetric concave inwards could be formed by more than one curved surfaces.
  • Said water intake port (420) is placed on the outer shell (400) bottom (480), and at wheel/roller front and/or rear side.
  • Fig 6 shows the construction of swimming pool cleaner in application example #3.
  • said water intake port (420) is placed on outer shell (400) bottom (480) and at right under the wheel/roller. That location has the lowest clearance between swimming pool cleaner and swimming pool floor. Place the water intake port (42) here could make the dirt and debris be suck up into the swimming pool cleaner easier. Said water intake port (420) has opening downwards.
  • this invention having the swimming pool cleaner bottom is concave inwards which allows it overcomes swimming pool floor obstacles when it runs in a swimming pool. It can improve the swimming pool cleaner cleaning efficiency, reliability and lower the cost of maintenance.
