The invention relates to systems and apparatuses for cleaning water-containing vessels such as swimming pools and spas and more particularly, although not necessarily exclusively, to pool equipment such as but not limited to automatic swimming pool cleaners (APCs).
Numerous cleaning devices capable of autonomous movement within swimming pools and spas currently exist. The most common of these devices are APCs, which often are either hydraulic or robotic in type. Hydraulic cleaners vary water flow for movement, while robotic cleaners typically employ electric motors to cause motion. Hydraulic APCs, furthermore, subdivide into “pressure-side” and “suction-side” cleaners, with pressure-side cleaners being fluidly connected to outputs of pumps of pool water circulation systems and suction-side cleaners being fluidly connected to inputs of such pumps.

According to some embodiments, an APC for a swimming pool or spa may maintain a wet probe while (i) immersed in the swimming pool or spa and (ii) removed from the swimming pool or spa.
According to various embodiments, an APC for a swimming pool or spa may maintain a water treatment feature within a wet cavity while (i) immersed in the swimming pool or spa and (ii) removed from the swimming pool or spa.
According to certain embodiments, pool equipment for a swimming pool or spa may include a cavity for retaining water when a flow of water through the pool equipment is disrupted and/or halted.
According to some embodiments, pool equipment for a swimming pool or spa includes a sealable cavity for (i) allowing a flow of water through the cavity and (ii) maintaining the cavity with water when the flow of water is disrupted or halted.
According to various embodiments, pool equipment for a swimming pool or spa may maintain a wet probe when a flow of water through the pool equipment is disrupted or halted.
Various implementations described herein can include additional systems, methods, features, and advantages, which cannot necessarily be expressly disclosed herein but will be apparent to one of ordinary skill in the art upon examination of the following detailed description and accompanying drawings. It is intended that all such systems, methods, features, and advantages be included within the present disclosure and protected by the accompanying claims.
The specification makes reference to the following appended figures, in which use of like reference numerals in different figures is intended to illustrate like or analogous components.
Described herein are pool equipment for swimming pools or spas that maintain a cavity full of water. Such pool equipment includes, but is not limited to, APCs, heat pumps, and/or other pool equipment as desired. In certain embodiments, the pool equipment maintains the cavity full of water when the flow of water through the pool equipment is disrupted and/or halted. In one non-limiting example, the pool equipment is an APC that maintains a cavity full of water when removing the APC from a swimming pool or spa and allow a flow of water through the cavity when the APC is immersed in the swimming pool or spa. In some embodiments, the cavity may allow for a flow of “fresh” water from the pool through the cavity when the APC is at least partially submerged and/or cleaning the pool. In certain embodiments, the cavity is selectively sealable such that water may flow through the cavity while the APC is immersed but water is maintained within the cavity when the APC is removed from the swimming pool. The cavity may be a cavity of the APC (and/or other pool equipment) and/or may be part of a sub-system that is detachable from the APC (and/or other pool equipment).
Some features or components of pool equipment such as heat pumps and APCs may need to be permanently wet to be operational, and pool equipment with the cavity described herein allow for such features or components to be maintained in a wet state. As a non-limiting example, a water sensing probe may need to be permanently wet to be operational, and the pool equipment described herein may receive the probe within the cavity and keep the probe wet. As an example, the pool equipment is an APC, and the probe within the cavity may be kept when removing the APC from the swimming pool while also allowing the probe to sense water when the APC is immersed. As another non-limiting example, a water treatment feature such as but not limited to a chemical tablet (e.g., a chlorine tablet) may be provided within the cavity, thereby allowing the APC (and/or other pool equipment) to manage a chemical level (e.g., chlorine level) within the pool by diffusing the chemical (e.g., chlorine) into the pool when the APC is immersed. In certain embodiments, the cavity described herein optionally uses pump overpressure to drive clean fluid (e.g., downstream from a filter of the APC) into the cavity and to push the old fluid outside the cavity. In various embodiments, a conduit (flexible conduit, rigid conduit, etc.) may fluidly connect the cavity with the pump (or other portion of the APC as desired), thereby allowing the cavity to be provided at any location on the APC and/or pool equipment as desired such as within a body cavity defined by a body of the APC and/or pool equipment, within a cover cavity defined by a cover of the APC and/or pool equipment, external to the body of the APC and/or pool equipment, etc. Various other benefits and advantages may be realized with the devices and methods provided herein, and the aforementioned advantages should not be considered limiting.
The APC 10 generally includes a body 16 and one or more motive elements 18 (e.g., wheels, tracks, feet, etc.). A pump 20 (see
Referring to
The container 12 includes an inlet 22 and an outlet 24 for the cavity 14. Optionally, the inlet 22 and/or the outlet 24 may include a flow control mechanism such as but not limited to a check valve 25. While the check valve 25 is illustrated at the outlet 24 in
In the embodiment illustrated, the inlet 22 is in fluid communication with the pump 20 of the APC 10, and in particular is in fluid communication with an overpressure area 28 of the pump 20 (e.g., downstream from filtration of the APC 10 and over an impeller 32). In this embodiment, pump overpressure may be used to drive water through the conduit 26 and into the cavity 14 while also forcing water within the cavity 14 out the outlet 24 when the pump 20 is operational and/or the APC 10 is submerged. In other embodiments, the cavity 14 may be fluidly connected to other regions or areas of the APC 10 as desired such that water flows into and through the cavity 14 when the APC 10 is immersed and/or operational within the water of the swimming pool.
In various embodiments, when the APC 10 is removed from the swimming pool, the inlet 22 and the outlet 24 may self-seal (e.g., due to water surface tension and/or water pressure force) to minimize and/or prevent water from escaping the cavity 14. Optionally, a flow controller such as but not limited to the check valve 25 may be provided with the inlet 22 and/or the outlet 24 to further secure the inlet 22 and/or the outlet 24 and minimize leakage from the cavity 14.
In this way, the APC 10 may maintain water within the cavity 14 both when the APC 10 is removed from the swimming pool and when the APC 10 is immersed. The APC 10 with the water-filled cavity 14 may be used for various features or components of the APC 10 as desired.
In the embodiment illustrated in
In another embodiment, the cavity 14 may contain a water treatment feature such as but not limited to a chemical tablet, such as but not limited to a chlorine tablet. In this embodiment, the chemical and/or chlorine tablet may be maintained in a wet state, and chlorine may diffuse into the pool based on water flowing into and through the cavity 14 due to the cavity 14 being immersed and/or the APC 10 being operational within the pool.
The aforementioned examples of features provided within the water-filled cavity 14 are for illustrative purposes only and should not be considered limiting, and in other embodiments, other types of features may be provided within the cavity 14 as desired.
Exemplary concepts or combinations of features of the invention may include:
These examples are not intended to be mutually exclusive, exhaustive, or restrictive in any way, and the invention is not limited to these example embodiments but rather encompasses all possible modifications and variations within the scope of any claims ultimately drafted and issued in connection with the invention (and their equivalents). For avoidance of doubt, any combination of features not physically impossible or expressly identified as non-combinable herein may be within the scope of the invention. Further, although applicant has described devices and techniques for use principally with APCs, persons skilled in the relevant field will recognize that the present invention conceivably could be employed in connection with other objects and in other manners. Finally, references to “pools” and “swimming pools” herein may also refer to spas or other water containing vessels used for recreation, training, or therapy and for which cleaning of debris is needed or desired.
