PROBLEM TO BE SOLVED: To provide a compact dissolving device which requires no electric circuit, operates at low cost and supplies an inorganic compound or the like, and to provide a device for supplying hot water including the same.SOLUTION: The dissolving device includes: a water circuit 15 and a casing body 13 for surrounding the inorganic compound 11 composed of powder or granules, or formed by mixing the powder and the granules. The dissolving device is configured to discharge the water containing the dissolved inorganic compound 11 from the water circuit 15. The dissolving device dissolves the inorganic compound with water on the principle of substance diffusion (Ficks law), in which a substance moves due to the dissolution concentration difference between water and the inorganic compound.COPYRIGHT: (C)2012,JPO&INPIT【課題】電気回路を必要とせず、コンパクトで運転コストが安価な無機化合物等を供給する溶解装置及びそれを備えた給湯装置を提供すること。【解決手段】水回路15と、粉末状または顆粒状、あるいは、粉末状と顆粒状との混合物である無機化合物11を包囲する包装体13とを備え、前記無機化合物11を溶解させた水を、前記水回路15から流出させる構成としたことを特徴とする溶解装置で、水と無機化合物の間の溶解濃度差で物質が移動する、物質拡散(フィックの法則)の原理で、水に無機化合物を溶解させることが可能となる。【選択図】図1
