Heat exchange device for hot water of shower and bath

Abstract

The present invention is to provide a heat exchange device for hot water of shower and bath, which comprises a trough base, a metal heat exchanging plate and a diversion plate, wherein, said trough base of hollow cuboid with a top opening on the upper side has a water inlet and a water outlet respectively configured on one pair of corresponding flanks thereat; said metal heat exchanging plate has a plurality of round sinks orderly arrayed on the top surface thereof as well as a inlet orifice and a outlet orifice respectively perforated on one pair of sides corresponding to the flanks of said trough base; And said diversion plate, which being securely attached onto the internal bottom surface of said metal heat exchanging plate, has some isolating raised bars protruded on the top surface thereat. By means of every round sink on the metal heat exchanging plate and the isolating raised bar on the diversion plate, the showered hot water will constantly sprinkle over said metal heat exchanging plate after having showered over the bather body; By means of with uniform specification in design and fabrication so that such multiple heat exchange devices can be jointly arranged and combined in accordance with the sprinkling floor area of the bathing room; Thereby, the showered hot water can be fully collected and utilized to provide more heating source for heat exchange so as to enhance the energy-saving effect in heating action of the water heater.

1 . A heat exchange device for hot water of shower and bath comprises:
 a trough base, which is a hollow cuboid with a top opening on the upper side, has a water inlet and a water outlet respectively configured on one pair of corresponding flanks thereat;   a metal heat exchanging plate, which being embedded into said trough base via said top opening, has a plurality of round sinks orderly arrayed on the top surface thereof as well as a inlet orifice and a outlet orifice respectively perforated on one pair of sides corresponding to both of said water inlet and water outlet on the flanks of said trough base; and   a diversion plate, which being embedded into said trough base and securely attached onto the internal bottom surface of said metal heat exchanging plate, has some isolating raised bars protruded on the top surface thereat so that a fluent flow duct is created in the space between rows of said round sink array on said heat exchanging plate.   
   
   
       2 . A heat exchange device as recited in the  claim 1 , wherein said both of water inlet and water outlet of said trough base are configured on other flanks of said trough base. 
   
   
       3 . A heat exchange device as recited in the  claim 1 , wherein said a plurality of oval sinks is orderly arrayed on the top surface of said metal heat exchanging plate. 
   
   
       4 . A heat exchange device as recited in the  claim 1 , wherein said a plurality of parallel strap sinks is arranged on the top surface of said metal heat exchanging plate, and the diversion plate is configured into plate shape; Thereby, a fluent flow duct is created in the space between rows of parallel strap sinks so long as the bottom side of said parallel strap sinks closely attaches with the top surface of said diversion plate. 
   
   
       5 . A heat exchange device as recited in the  claim 1 , wherein said metal heat exchanging plate is further configured into continuous corrugation. 
   
   
       6 . A heat exchange device as recited in the  claim 1 , wherein both of said metal heat exchanging plate and diversion plate are interchangeable from upside to downside then embedded into the trough base. 
   
   
       7 . A heat exchange device as recited in the  claim 1 , wherein the bottom side of said trough base is concaved into a hollow trough; and a plurality of enclosed cavities is formed in the space after closely attaching the diversion plate with the metal heat exchanging plate; Then a inlet orifice and a outlet orifice are perforated among said multiple enclosed cavities; Besides, an additional nipple plate is further overlaid onto said diversion plate. 
   
   
       8 . A heat exchange device as recited in the  claim 1 , wherein said two pairs of the metal heat exchanging plate and the diversion plate are stacked and embedded in said trough base with the water inlet of the trough base connecting to one of the enclosed cavities at the upper stack and the water outlet of the trough base connecting to one of the enclosed cavities at the lower stack as well as a connecting pipe linking both of upper stack and lower stack; Besides, some drain orifices are perforated in the central bottom portion of said trough base such that top opening of said drain orifice connecting with diversion plate of the lower stack.
