  • Patent number: 8392027
    Abstract: A spa control system that measures the flow of water through the heater and accurately reports water temperature in the spa using only one solid-state sensor in the heater. The rate of flow is determined by energizing the pump, with the heater still de-energized, and observing the rate in which the moving water cools the inside of the heater. If there is no circulation of water through the heater, the temperature of the sensor will continue to rise from the energy applied when the heater was briefly energized. This rise will be quite significant and a clear indication of a flow problem. If the flow is found to be adequate, the heater will be energized for a normal period of time. The sensor is now carefully monitored for a sudden increase in temperature, which would indicate loss of a normal flow of water.

  • Patent number: 6756567
    Abstract: An apparatus for melting paraffin wax is provided. It includes an integral plastic inner tub attached to an integral aluminum plate holder, each of which has a flat bottom and a sloped wall. A positive temperature coefficient heating element is attached to the flat bottom of the aluminum plate holder for self regulating to a preset temperature by autonomously varying the positive temperature coefficient heating element electrical resistance in response to the temperature of the positive temperature coefficient heating element thereby varying a power dissipation of the positive temperature coefficient heating element in order to maintain the positive temperature coefficient heating element at the preset temperature. Heat from the positive temperature coefficient heating element is transferred from the integral aluminum plate holder to the integral plastic inner tub via the flat bottoms and the sloped walls thereby melting any wax inside the integral plastic inner tub.

  • Patent number: 6747367
    Abstract: A control system for a pool and spa. Main line voltage is provided through a single line voltage service and a single ground fault circuit interrupter circuit, facilitating a ground fault test and simplifying installation. The control system acts as a power distribution system for controlling the pool and spa equipment, with a circuit board assembly including individual fuse protection devices and switching circuits. A test algorithm is included, wherein the control system is disabled from normal operation if the GFCI test fails. The pool operator manually enters a water fill command, and the controller system automatically opens the fill valve for a predetermined time interval, and then automatically closes the valve. An emergency disconnect switch is mounted near the bathing area, connected by low voltage wiring to the controller system cabinet. The controller system senses the emergency switch closure and disconnects line voltage to the line voltage loads.

  • Patent number: 6670584
    Abstract: A process of electrically heating a spa having electrically operated devices connected to the spa, such as one or more water pumps, lights, and at least two heaters, in an environment in which there is not enough current to operate all spa devices simultaneously. The process includes the steps of providing a control system with data as to which devices are connected to the spa and how much current each device requires, and how much current is available to the spa. Next, the amount of current that is being used by the devices currently operating, other than the two heaters, is calculated. This provides the amount of the residual current available. If the spa water temperature is below a desired temperature, a determination is made as to whether there is enough current to operate one or both spa heaters and either one heater or both heaters are turned on based upon this calculation.

  • Patent number: 6571789
    Abstract: Presented is an improved insulation device which, in multiple numbers, forms a swimming pool cover, or cover for other types of liquid containers. A complete cover is formed of multiple independent floatation insulation devices that collectively cover the entire surface of the water or liquid on which they float, yet enable dispersion thereof as a safety feature from below the surface of the water or liquid by a person in the water so that the person may extend his or her head through the cover to breath air. Structurally, the insulation device is hexagonal so as to cooperatively abut adjacent insulation devices to form a complete cover. The insulation device is injection molded-from plastic in two mirror image half-shells each of which is formed with a circular recess centrally disposed within the hexagonal outer periphery.
