Benefits of technology

[0014]The toilet includes a holding tank preferably having a vent leading outside of the enclosure to vent gases produced by sewage stored in the holding tank. To generally prevent freezing of the sewage within the holding tank and water within the water tank, the portab...

Problems solved by technology

Keeping sewage at a temperature above freezing can be particularly challenging in areas where the temperature outside is below freezing.
Using salt brine is labor intensive because of the need to store enough salt and to mix the brine in effective proportions.
Being a petroleum product, the cost of methanol is increasing daily.
If the portable toilet owner is dumping the raw sewage in a rural environment, methanol has a negative effect on environmental quality and may be considered a pollutant.
The disposing of any methanol, wherever, has a negative environ...

Embodiment Construction

[0023]FIG. 1 illustrates a preferred portable toilet satellite station 10. The portable toilet satellite station 10 includes an enclosure 12 having a front wall 14 having a door (not shown), rear wall 18, side walls 20a, 20b and a roof 22. The enclosure 10 further includes an inside area 24 at least partially defined by the front wall 14, rear wall 18, side walls 20a, 20b and the roof 22. The inside area 24 is generally the area in which a user would move about when using the satellite station 10. Within the inside area 24, a toilet 26 and, optionally, a urinal (not shown) are located. The toilet 26 and urinal are interconnected to a holding tank 28 having a tank interior 30 in which sewage (not shown) is stored until it can be disposed. In preferred embodiments, the holding tank 28 contains a deodorizing liquid (not shown) as is commonly used. The preferred holding tank 28 is vented with a vent pipe 32 extending upwardly from the holding tank 28 and then outside of the enclosure 12...

Abstract

A portable toilet satellite station comprising an enclosure having a front wall, rear wall, side walls and a roof. The enclosure further having an inside area at least partially defined by the front wall, rear wall, side walls and the roof. The portable toilet satellite station further including a toilet having a holding tank. The portable toilet satellite station further including a heating system in communication with the holding tank. The heating system is capable of producing warmed air that can be directed through the heating pipe and into the holding tank and preferably also the inside of the enclosure to warm a user.

Description

RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Application Ser. No. 61 / 030,274, filed Feb. 21, 2008, entitled “Holding Tank Heating System,” the disclosure of which is hereby incorporated by reference.BACKGROUND OF THE DISCLOSURE[0002]1.
