Heat exchanger for bathing shower

Abstract

The present invention provides a heat exchanger for bathing shower comprising an upper deck, a lower chassis and two hatches. On the bottom surface of the upper deck are disposed several parallel septa, whose integral propping strength is good enough to support maximal body weight of a bathing user. After having assembled, the circulation of internal water passages is configured into a continual zigzag duct to increase energy saving effect in consequence of improvement in heat exchanging efficiency of the water heater. With simple structure, it is easily fabricated by traditional extruding method without welding process and related welding technician. Thereby, selling price is reduced with marketing competitiveness because overall manufacturing cost is decreased so that the purchasing intention of the consumers is spurred. Thus, it is not only favorable to promote and penetrate marketing range and depth but also valuable to achieve energy saving and carbon reducing effect.

1 . A heat exchanger for bathing shower, comprising:
 a stacked upper deck;   a founded lower chassis ; and   two hatches,   wherein said upper deck is a planiform cuboid extruded by metal material and encompassed by a top surface, a bottom surface, a front side, a rear side, a pair of parallel flanks, includes several parallel septa downwardly disposed on the bottom surface such that a water passage is created between each pair of adjacent septa, an upper docking latch bar being downwardly formed on the terminal of one septum, a circulating bore being created on each septum in interlaced stagger manner, which means a circulating bore in upper section of one septum and another circulating bore in lower section of the other septum for each pair of adjacent septa, a water intake is created in one flank while a water outtake is created in the other opposed flank respectively,   wherein said lower chassis is a planiform slab extruded by metal material and encompassed by a top surface, a sole surface, a front side, a rear side, a pair of parallel flanks with same planar shape and area with corresponding upper deck, includes a lower docking latch bar, which is upwardly formed on the top surface in a suitable position corresponding to the upper docking latch bar of the specific septum on the upper deck so that the upper docking latch bar and the corresponding lower docking latch bar can be securely engaged in mutual latch manner, and   wherein said each hatch is a planiform slab with suitable planar shape and area to properly cover an interim integral assembly of the upper deck and lower chassis in flush maimer, includes all water passages of continual zigzag circulating duct with septa in the interim integral assembly of the upper deck and lower chassis.   
     
     
         2 . A heat exchanger for bathing shower as claimed in  claim 1 , wherein a plurality of screw bores are further respectively created in the front side and rear side for the upper deck and the lower chassis, and an equivalent number of plural corresponding punched holes are also disposed on both of front and rear hatches in corresponding to the screw bores on the upper deck or screw bores on the lower chassis so that both of front and rear hatches can hermetically seal both front sides as well as both rear sides of the interim integral assembly of the upper deck and lower chassis in plenum manner. 
     
     
         3 . A heat exchanger for bathing shower as claimed in  claim 1 , said upper deck is further modified to dispose an inward flank latch bar on each flank thereof while said lower chassis is further modified to dispose a corresponding outward flank latch bar on each suitable marginal position of upper surface thereof. 
     
     
         4 . A heat exchanger for bathing shower as claimed in  claim 1 , said upper deck is further modified to dispose a upper docking latch bar on every septa on the bottom surface thereof while said lower chassis is further modified to dispose a corresponding equivalent number of lower docking latch bars on each suitable marginal position of upper surface thereof. 
     
     
         5 . A heat exchanger for bathing shower as claimed in  claim 1 , wherein said upper docking latch bar is male dovetailed cross section while said lower docking latch bar is female dovetailed cross section. 
     
     
         6 . A heat exchanger for bathing shower as claimed in  claim 4 , wherein said upper docking latch bar is male dovetailed cross section while said lower docking latch bar is female dovetailed cross section. 
     
     
         7 . A heat exchanger for bathing shower as claimed in  claim 3 , wherein said inward flank latch bar on the upper deck is male dovetailed cross section while said outward flank latch bar in the lower chassis is female dovetailed cross section, and vice versa. 
     
     
         8 . A heat exchanger for bathing shower as claimed in  claim 1 , wherein said top surface on the upper deck is modified into a cambered top surface. 
     
     
         9 . A heat exchanger for bathing shower as claimed in  claim 1 , wherein the metal material used in said upper deck is replaced by a non-metal synthetic material with good heat conductivity. 
     
     
         10 . A heat exchanger for bathing shower as claimed in  claim 1 , wherein said upper deck is modified to split into a primary upper deck and an annexed subordinate upper deck while the lower chassis is also split into a corresponding primary one and a subordinate one such that an additional recessed linking elbow bar is disposed on a flank of the primary upper deck while an additional corresponding projected linking elbow bar is disposed on a flank of the annexed subordinate upper deck, as well as a plurality of screw bores are formed in the recessed linking elbow bar while a plurality of punched holes are perforated in the projected linking elbow bar. 
     
     
         11 . A heat exchanger for bathing shower as claimed in  claim 1 , wherein each internal hatch face of said front hatch and rear hatch is modified to inwardly create an array of terminal linking passages of zigzag end therein to replace the function of the circulating bores or circulating notches; after having securely engaged the integral assembly of the upper deck and lower chassis as well as modified hatches by screws, a configuration of zigzag circulation from combination of water passages and terminal linking passages is finished. 
     
     
         12 . A heat exchanger for bathing shower as claimed in  claim 1 , wherein said circulating bores created on every septa of the upper deck in interlaced stagger manner are replaced by equivalent circulating notches cut out in indented manner.
