COMPOSITE HEATING DEVICE USING HEAT STORAGE SAND

The present invention relates to a composite heating device using heat storage sand and, more particularly, to a composite heating device wherein a heat storage tank is configured to facilitate secondary heating of heat storage sand by magnetic energy at a predetermined temperature such that a hot fluid (water) can be discharged; heat stored in the heat storage tank is transferred by discharging a wind, which is used as a warm wind; a hot fluid primarily heated in the heat storage tank is used as water circulating through a warm-water mat and/or a kotatsu; and the hot fluid is then introduced into the heat storage tank and secondarily heated. A composite heating device using heat storage sand according to an embodiment of the present invention comprises: a heating tank provided inside a main unit, a first heating body being arranged on the heating tank so as to primarily heat water contained therein; a circulating pump for pumping and circulating the water in the heating tank; a three-way valve having three valves (first, second, and third valves), the first valve being connected to the circulating pump; a heat storage tank having a second heating body arranged at the center inside a barrel, the heat storage tank having a water channel tube positioned outside the second heating body and connected to the second valve, and the heat storage tank having heat storage sand configured to fill the remaining space; a heat exchanger for warming air through heat exchange; a blowing fan for discharging the air, which has been warmed by the heat exchanger, to the outside of the main unit; and an outer device connected to the third valve and provided outside the main unit such that the same is heated by warm water. La présente invention concerne un dispositif de chauffage composite utilisant du sable de stockage de chaleur, plus précisément un dispositif de chauffage composite dans lequel un réservoir de stockage de chaleur est conçu pour faciliter un chauffage en un second temps du sable de stockage de chaleur au moyen d'une énergie magnétique à une température prédéterminée d'une manière telle qu'un fluide chaud (de l'eau) peut être déchargé. La chaleur stockée dans le réservoir de stockage de chaleur est transférée en déchargeant un flux d'air utilisé à titre de flux d'air chaud. Un fluide chaud chauffé en un premier temps dans le réservoir de stockage de chaleur est utilisé à titre d'eau circulant à travers un tapis à eau chaude et/ou un kotatsu. Le fluide chaud est
