The present invention has the aim of solving the problems of conventional thermal therapeutic apparatuses, and provides a foldable thermal therapeutic apparatus comprising a left unit, a right unit, and a center unit, wherein the left unit and the right unit are foldable onto the center unit. The left unit and the right unit are unfolded from the center unit during use, and folded onto the center unit when not in use and stored or carried, thereby reducing the volume of the apparatus for easy storage and portability. The present invention can be folded or unfolded in a simple manner to overcome inconveniences in use. For this purpose, the present invention comprises: a left heater (10) having an inner surface on which a first heating portion (11) is formed; a central heater (20) having an inner surface on which a second heating portion (21) is formed and electrically connected to the first heating portion (11) of the left heater (10); and a right heater (30) having an inner surface on which a third heating portion (31) is formed and electrically connected to the second heating portion (21) of the central heater (20). The left heater (10), the central heater (20), and the right heater (30) are interconnected and folded and unfolded by folding units (40) arranged along contacting edges of the left heater (10), the central heater (20), and the right heater (30). Each of the folding units (40) includes: fitting groove portions (41) formed at both side edges of the central heater (20), respectively; fitting portions (42) formed at the edges of the left heater (10) and the right heater (30), respectively, and contacting both of said side edges of the central heater (20), such that the fitting portions (42) are fitted to the fitting groove portions (41) formed at both side edges of the central heater (20), respectively; fitting protrusions (43) protruding from both side surfaces of each of the fitting portions (42); and covers (44), each of which is coupled to an inner surface of each of the fitting groove portions (41) to protect the fitting groove portions (41) and the fitting portions (42). |
