Thermal accumulation type heating and cooling device using heat transfer medium

A heating device comprising:

• a heat exchange tank having a lower portion, an upper portion, a bottom wall, and at least one upstanding sidewall;
• a heat transfer medium received in said heat exchange tank, said heat transfer medium comprising water;
• heating means disposed below said bottom wall of said heat exchange tank for heating said heat transfer medium, said heat transfer medium normally having a first temperature adjacent said lower portion of said heat exchange tank and a second increased temperature adjacent said upper portion;
• a heat exchange pipe extending through said heat transfer medium, said pipe having a substantially horizontal inlet end extending through the sidewall of the heat exchange tank adjacent to said lower portion thereof and a substantially horizontal outlet end extending outwardly through the sidewall of the heat exchange tank adjacent to said upper portion thereof, said heat exchange pipe a plurality of substantially horizontal pipe sections and a plurality of reversely bent pipe sections which wind back and fourth through said heat transfer medium;
• a frusto-conical air discharge member mounted on said outlet end of said heat exchange pipe;
• an air suction member mounted on said inlet end of said heat exchange pipe;
• fan means mounted in said air discharge member for drawing a volume of ambient air into said heat exchange pipe, said ambient air entering said heat exchange pipe through said air suction member at said inlet end and flowing through said horizontal pipe sections to become gradually heated as it flows from said lower portion of said heat exchange tank toward said upper portion of said heat exchange tank, said heated air being discharged through said air discharge member at said outlet end of said heat exchange pipe;
• inlet means in the sidewall of said heat exchange tank adjacent the upper portion thereof for filling said tank;
• outlet means in the bottom wall of said heat exchange tank for discharging said tank;
• and
• temperature sensor means mounted on said sidewall of said heat exchange tank adjacent the lower portion thereof for sensing a temperature of said heat exchange medium.
