2. A device according to claim 1, wherein the pump is connected to an intake end of the input hose such that the pump is positioned in the pool to pump the water into the watertight reservoir.

3. A device according to claim 1, wherein the pump is connected between the input hose and the watertight reservoir to pump the water into the watertight reservoir.

4. A device according to claim 1, wherein the pump is fixedly connected to the watertight reservoir to pump the water from the input hose into the watertight reservoir.

5. A device according to claim 1, wherein the heating element includes a shutoff sensor operatively connected to turn off the heating element when the reservoir is tipped over.

6. A device according to claim 1, wherein the heating element includes a thermostat control switch operatively connected to turn off the heating element when a predetermined maximum temperature is reached.

7. A device according to claim 2, wherein the pump is configured as a low energy pump with a safety filter on an input side of the pump.

8. A device according to claim 1, wherein the watertight reservoir is formed double insulated and configured to be resistant to tipping over.

9. A device according to claim 1, further comprising: a float sensor operatively connected to the watertight reservoir to controllably turn off the heating element when water in the watertight reservoir is below a predetermined threshold level.

DETAILED DESCRIPTION OF THE INVENTION

[0032] The present invention is a portable kiddie pool heater 100 designed for everyday use. (FIG. 1 and FIG. 2) The heater 120 plugs into a standard 120-volt power outlet and is used to heat an already filled kiddie pool 140. The present invention uses a self-priming pump 160. The self-priming pump 160 uses a diaphragm design to move air or water. The pump will run on 6 to 12-volt direct current with a flow of 2 to 10 liters per minute and a vertical suction lift of at least 5 feet. The pump will be used to draw water from the kiddie pool 140 via the flexible vinyl inflow hose 340. The inflow hose will empty into an insulated inner reservoir 180. Electrical components are mounted on the outside of the inner reservoir, which is covered by an outer protective casing. Insulation between the inner reservoir and outer casing is achieved with air. Once inside, the water is warmed with an Underwriters Laboratory-approved 1500-watt, 120-volt, high-density water heating element 200. As the reservoir 180 continues to fill, warm water is returned to the pool 140 via the flexible vinyl outflow hose 360.

[0033] The portable kiddie pool heater 100 includes multiple safety features including (see FIG. 1): a thermostat control switch 220 consisting of a waterproof negative temperature coefficient thermistor that automatically turns off the unit once a predetermined maximum temperature is reached; a metallic ball design tilt angle sensor 240 that will immediately turn off the unit if it is tipped over; and a water level float switch similar to those used in fish tanks 260 that allows power to the heating element only when it is fully submerged in water; a double-insulated design that separates water from electrical components and electrical components from product users (see FIG. 1); a waterproof extension cord gasket 280 specially designed to protect from short-circuiting; and screens 300 at the end of both inflow and outflow hoses 340,360 for safety purposes and to prevent debris from entering the reservoir 180. (FIG. 3)

[0034] Additional features include a carrying handle 380, a mesh bag 400 to store the inflow and outflow hoses 340,360 (FIG. 4) and attached hooks 460 to wrap and secure the electrical cord 420. (FIG. 5). The portable kiddie pool heater 100 also features a large drain 440 to allow the egress of water once heating is finished. When stored, the large drain 440 can be left open to allow the reservoir 180 to dry and to prevent the buildup of mold and other contaminants (see FIG. 5).

[0035] Although the present invention has been fully described in connection with the preferred embodiment thereof with reference to the accompanying drawings, it is to be noted that various changes and modifications will be apparent to those skilled in the art. For example, the portable kiddie pool heater according to the present invention may include additional safety features to improve use or safety among children, and to improve use among pets. The portable kiddie pool heater 100 may include additional temperature sensors on more or different parts of the unit intended to measure water temperature or the temperature of the device itself, such as a temperature sensor on the outbound hose. Additionally, the portable kiddie pool heater 100 may include use of more than one heating coil, or use of a different style, shape or intensity heating coil. The portable kiddie pool heater 100 may also include a different heating element in addition to or besides a coil. The pump device of the portable kiddie pool heater 100 may be modified to use a different style pump, including a pump that is not self-priming; or a pump that is located in a different spot. The portable kiddie pool heater 100 may be changed so that it needs to be powered with greater than 120 V. The inflow and outflow hoses may be combined into a single unit. The lengths of the inflow and outflow hoses may be modified to increase the distance of the device from the kiddie pool. The portable kiddie pool heater 100 may also be altered so that it can be powered by a battery. Such changes and modifications are to be understood as included within the scope of the present invention as defined by the appended claims, unless they depart therefrom.
