Field of the Invention
The present invention generally relates to spa devices, components, and systems. More specifically, the present invention is directed to a pump having a contactless, fluid sensor for dispensing a fluid to a setting and for use with a liner, to a pump apparatus comprising a pump having a contactless, fluid sensor for dispensing a fluid to a setting and for use with a liner, and to a method for dispensing a fluid to a setting by use of a pump having a contactless, fluid sensor for use with a liner.
Description of the Related Art
Spa devices, components, and systems are known in the art. Spa devices are used in commercial and recreational settings for hydrotherapy, massage, stimulation, pedicure, and bathing purposes. In the spa application setting, the issues with sanitization in the spa industry today require the use of a liner, such as a disposable liner. But with a liner, traditional water sensors in spa devices and settings, such as foot spas, will not be able to effectively detect fluids or water anymore. Thus, there exists a need for a pump having a contactless, fluid sensor adapted for use with a liner for dispensing a fluid to a setting such that fluid or water level can be effectively detected in a setting, such as, but not limited, a foot spa, a spa, a jacuzzi, a bathtub, or a swimming pool.
In addition, typical spa devices include a motor that drives a pump to circulate water from the spa device. In particular, a shaft of the motor is used to directly mount an impeller, which is then used to circulate water into and out of the spa device. Since the motor may not operate wet, a seal or a series of seals may be required to prevent water from entering the motor. The seals will wear to the point where water will enter the motor and consequently, the entering water may cause the motor to burn out. At this point, the motor assembly will need to be replaced in order to continue operation. This is expensive and may take several hours in which to perform.
Further, because typical spa devices have extensive piping systems that are built into the spa device to transport water, the spa devices are traditionally difficult to clean. This results in downtime and complicated maintenance schedules to clean such spa devices. Furthermore, if a spa device has a light source associated with it, to replace or repair such a light source can be time consuming and complicated when the light source is not easily accessible.
In the spa environment, water is commonly added with certain substances and/or products, such as salt, chemicals, sand, massage lotions, etc. Due to this reason, traditional bearings, such as ball bearings and metal bushings, will not be suitable for a long term and reliable operation. The presence of chemicals and sand, for example, will cause some or many currently available bearings to wear out quicker than normal and result in pump failures.
Additionally, for magnetic coupling-type pumps, it is almost impossible to have a perfect alignment between the motor shaft axis and the impeller rotation axis. The imperfect alignment or misalignment will result in high vibration noise.
The present invention overcomes one or more of the shortcomings of the above described spa devices, components, and systems. The Applicant is unaware of inventions or patents, taken either singly or in combination, which are seen to describe the present invention as claimed.
In one exemplary aspect, the present invention is directed to a pump having a contactless, fluid sensor for dispensing a fluid to a setting and for use with a liner. The pump comprises a jet assembly, a motor assembly, and a contactless, fluid sensor assembly with a contactless, fluid sensor. The pump may further comprise a mounting housing member or coupling device, a gasket or seal, and a liner when a liner is not already present.
In another exemplary aspect, the present invention is directed to a pump apparatus comprising a pump having a contactless, fluid sensor for dispensing a fluid to a setting and for use with a liner. In addition to comprising the pump, the pump apparatus further comprises a power source for providing power to the pump, and/or a control apparatus.
The jet assembly is secured, attached or coupled to the motor assembly.
In a non-limiting embodiment, the jet assembly includes a jet assembly housing, and preferably also includes a printed circuit board (PCB), a PCB cover, a shaft assembly, and an impeller.
The jet assembly housing includes a base, a front or top cover, an impeller-receiving chamber defined by the base and front or top cover, at least one inlet aperture dimensioned and configured to allow a fluid to enter the jet assembly housing, and at least one outlet aperture dimensioned and configured to allow the fluid to exit or be dispensed from the jet assembly housing into a setting.
The shaft assembly includes at least the shaft member.
The impeller, preferably a magnetic impeller, is configured to rotate about the shaft member and to rotate within the impeller-receiving chamber such that rotation of the impeller causes fluid to enter or flow into the inlet aperture and to exit or flow out of the outlet aperture.
The motor assembly may include and/or be coupled to the power source that enables rotation of the shaft member and impeller.
The contactless, fluid sensor assembly includes a contactless, fluid sensor or sensor circuit board, and may also include a sensor cover and a sensor output data cable.
The contactless, fluid sensor may be secured, attached, fixed or mounted to any position on the other components of the pump, such as, but not limited to, the mounting housing member or coupling device, or even be positioned at a location away from the pump, that allows the sensor to be in operative communication with the other components of the pump whereby the contactless, fluid sensor is effective, especially when a liner is being used in or with the setting, in capacitive sensing of fluid or water level in the setting such that the amount or volume of fluid or water can be controlled.
In a further exemplary aspect, the present invention is directed to a method for dispensing a fluid to a setting by use of a pump having a contactless, fluid sensor adapted for use with a liner.
