FIELD OF THE INVENTIONThe invention relates to control of spa systems. More particularly, the invention relates to multi-function intelligent control of pedicure spa systems.
BACKGROUNDSpa systems, in particular, pedicure spa systems are becoming increasingly advanced with more and more functions being added thereto. Bacteria and viruses in the tub of pedicure spa systems is a health concern. Therefore, it is beneficial to have a sanitization feature that can sanitize the tub of the pedicure spa system. In addition, a jet pump is often desirable in a pedicure spa system to disturb the fluid that is in the tub of the pedicure spa system. In that regard, a control mechanism for the jet pump is desirable. Moreover, the temperature of the water for pedicure spa systems is challenging to regulate when performed by an operator. Therefore, it is beneficial to have a temperature sensing mechanism that can monitor the temperature of the water and provide feedback that can then be used to regulate the temperature of water into the tub. Also, additional lighting for the operator of the pedicure spa system (or technician providing pedicure services) is desirable. Moreover, having a water level sensor that can sense the level of water in the tub is desirable to ensure that the tub has a predetermined level of water therein. In this regard, the water level sensor is helpful to make sure the jet pump is not operating while the water level is below the jet pump. Also, the water level sensor is helpful to determine when the water level has reached a particular height with respect to the tub. Moreover, for drainage of the tub of a pedicure spa system it may be desirable or necessary to have a drainage pump that can remove the used water. In that regard, a control mechanism for the drainage pump is desirable.
It is desirable for pedicure spa systems to have the features noted above. An implementation having these features will entail control mechanisms, sensing, and monitoring requirements. Accordingly, what is desirable is a pedicure spa system that implements the features noted above and includes an integrated controller to control such features. Moreover, also desirable is a controller that is scalable so that it can be used to control many of the features noted above, or just a few of the features noted above. Also desirable is that the controller be partitionable in a manner so that only one partition is needed for retrofitting existing pedicure spa systems without requiring another partition of the controller.

As best seen in
Referring to
The temperature sensor 210 is coupled to the temperature sensor electrical connector 245 with electrical wires. The electrical wires receive signals from the temperature sensor 210 for processing by the electronic/firmware chamber. In addition, the ionizer sanitizer 205 is coupled to the sanitizer electrical connector 258 with electrical wires. In particular, each electrical wire is coupled to one of the electrodes 206, 207 for receiving signals from the sanitizer electrical connector 258 that cause the ionizer sanitizer 205 to inject sanitization ions into the water in the water mixing/sanitizing chamber. The display and controller connector 246 and the temperature setting switch connector 251 are respectively coupled to the display and control interface and the temperature control with electrical wires.

Referring to
When the water is in the water mixing/sanitizing chamber, the water is sanitized by the ionizer sanitizer 205. The electrodes 206, 207 of the ionizer sanitizer 205 receive signals from the sanitizer electrical connector 258 for regulating the ionization levels. For example, when the electrodes 206, 207 receive signals from the sanitizer electrical connector 258, the ionizer sanitizer 205 injects sanitization ions into the water in the water mixing/sanitizing chamber of casing 184. These injected sanitization ions kill the bacteria and viruses in the basin 24 of the tub 61. In due course, the water in the water mixing/sanitizing chamber is supplied to the basin 24. In particular, the water is forced out of the output water connector 216 through a tube and out of the waterfall 34. If the operator engages the shower wand 65, the water in the water mixing/sanitizing chamber is supplied to the shower wand 65. In particular, the water is forced out of the output water connector 215 through a tube and out of the shower wand 65.
The operator of the pedicure spa system 60 can engage the jet pump 66 (
When the operator is filling the basin 24 with water from the water mixing/sanitizing chamber, a water level sensor (not shown) that is installed on the outer surface of the basin 24 senses whether the water is at or below a predetermined level. The output of this water level sensor is coupled to the water level sensor connector 252 on the casing 185. In turn, these signals are processed by the electronics/firmware chamber to determine the proper course of action. For example, if the water level in the basin 24 is below a predetermined level the electronics/firmware chamber will continue to fill the basin 24 with water. Otherwise the electronics/firmware chamber will refrain from filling up the basin 24 by shutting off the valve that regulates the flow of water into the mixing/sanitizing chamber. In addition, if the water reaches another predetermined level that is undesirable the overflow 29 will allow the unwanted level of water to be drained from the tub 61.
The operator of the pedicure spa system 60 can drain the basin 24 by opening the drain stopper 28. The operator opens the drain stopper 28 by turning the overflow and drain opener 29. Then, the operator presses the discharge switch 38 to activate the discharge pump (not shown) that is located underneath the tub 23. The discharge pump sucks the water from the basin 24. In this regard, the basin 24 is drained and can be re-filled again for another user in the manner described above.

In further detail, the electronics and firmware chamber 105 includes firmware that allows a jet pump (not shown) in the pedicure spa system 400 to be turned on when the water level in the basin 24 has reached a predefined level. In particular, the water level sensor 314 monitors when the water in the basin 24 reaches a predetermined level. When the water in the basin 24 reaches the predetermined level the fluid level sensor 314 sends a signal to the water level sensor input 160 to indicate that the predetermined water level has been reached. In response to the indication that the water in the basin 24 has reached a predetermined level, the electronics and firmware chamber 105 turns on the jet pump of the spa system 400.
In an alternative embodiment, the electronics and firmware chamber 105 provides automatic shut-off of the flow of water from the fluid chamber 405 into the basin 24. For example, when the water in the basin 24 reaches a predetermined level the fluid level sensor 314 sends a signal to the water level sensor input 160 of the electronics and firmware chamber. In response to the indication that the water in the basin 24 has reached a predetermined level, the electronics and firmware chamber 105 controls the fluid valve 410 so that further water is prevented from flowing from the fluid chamber 405 into the basin 24.
In alternative embodiments, the faucet may also be replaced and retrofitted with the mixing/sanitizing chamber of casing 184. In some instances, an existing pedicure spa system may be retrofitted with additional features that require control and power supplies.
