Definitions

  • the following relates to devices for residential destination, specifically to electrical household appliances and gas household appliances. More specifically, it relates to a continuous flow water heater that uses gas for its operation, which its performance is not affected when operated at different altitudes above the sea level.
  • the causes of the drawbacks listed above may be focused on two representative changes that occur with increasing altitude: decreasing the amount of oxygen present in the air and the change in the density of the gases by the change in the atmospheric pressure.
  • American standards include the use of combustible gases at altitudes higher than 1000 meters above the sea level, performing an operation known as American derating; this practice seeks to reduce the thermal power of the products at a value about 4% for every 304 meters above the sea level where the equipment is operating, a situation which is in contrast to the requirement of use, because at higher altitudes to the sea, there are lower temperatures and higher thermal energy requirements.
  • American derating the safe operation is obtained but it creates problems of dissatisfaction on the user with the application since the user does not obtain the final temperatures which satisfy him/her.
  • Asian countries are those with the highest density in the manufacturing of continuous flow water heaters that operate with fuel gases, but in its commercial offer, they restrict the operation to countries like Peru and Venezuela because of the large urban settlements that have altitudes greater than 3000 meters above the sea level and in addition they have to make major technical efforts to use their products in other countries of the Andean region, in all cases sacrificing functional performance (end-user satisfaction) in order to not jeopardize the safety.
  • the present invention contemplates the design, development and manufacturing of continuous flow water heater which mitigates the effects of altitude ensuring proper operation under different atmospheric conditions present in the Andean region; in addition, the operation at low altitudes is also appropriate.
  • FIG. 1 Isometric view of the combustion system.
  • FIG. 2 Front view of the combustion system.
  • FIG. 3 Side view of the combustion system.
  • FIG. 4 Exploded view of the heater that mitigates the effect of altitude
  • the continuous flow water heater that attenuates the effect of altitude is composed of four basic elements, which interaction in the operation provide optimum performance in different climatic zones, without affecting product performance and ensuring user safety.
  • the four elements forming part thereof are:
  • the combustion system is composed of four parts: a rectangular bottom base made of injected aluminum ( FIG. 1-A , FIG. 2-A ) which includes two sections, a lower section ( FIG. 1-C , FIG. 2-C ) and an upper section ( FIG. 1-B and FIG. 4-B ).
  • Each section contains 4 channels ( FIG. 3-D , FIG. 4-D ) which are arranged horizontally, divided in the middle by a channel perpendicular to the previous channel ( FIG. 3-E , FIG. 4-E ). This will provide six cavities, separated into groups of three by the center channel ( FIG. 3-E , FIG. 4-E ). These channels allow the flow of gas.
  • the rectangular base has a variable length between 20 and 25 centimeters and a width varying between 8 and 15 centimeters.
  • the lower section ( FIG. 1-C ) has on its outer perimeters and the perimeters of the channels, one thin interior channel ( FIG. 4-F ), in which the heat-resistant paste is provided whereby both sections are assembled through a pressure pressing system.
  • the upper section consists of a die-cast aluminum cover ( FIG. 1-B and FIG. 4-B ) with 50 evenly distributed nozzles, with a diameter of less than one millimeter.
  • a distributor ( FIG. 1-G , FIG. 2-G , FIG. 3-G ) is located, which connects the main valve with the injector system.
  • the rectangular base elements comprise a on called unified fuel injection system.
  • the proposed system distributes the impulses and only runs with an assembly operation, improving air drag and decreasing the probability of failure by decreasing assembly operations with high risk of leakage problems.
  • the lower rectangular base is assembled to four mixers made of stainless steel ( FIG. 1-H , FIG. 2-H , FIG. 4-H ).
  • Said mixers comprise a set of defined geometry, being comparable to two opposed and overlapping triangles, so that the vertices thereof are in the center ( FIG. 1-N ) and the bases of said triangles form the ends of the mixers ( FIG. 1-P ).
  • the set of four mixers having a variable height between 8 and 11 cm, preferably a width varying between 8 and 15 centimeters, and a length varying between 20 and 25 centimeters. From the lower base of each mixer, two rectangular shape flat surfaces extend laterally ( FIG. 1-Q , FIG. 2-Q , FIG.
  • FIG. 4-Q which embrace each channel of the rectangular base on both sides, attaching thereto via two tabs, also of rectangular shape ( FIG. 1-M , FIG. 2-M , FIG. 3-M ). Accordingly, the adequate air entrainment with a ratio area/port neck area superior than conventional systems is ensured.
  • the body of the mixer is made of stainless steel that retains its technical specifications under high operating temperatures without problems of corrosion or structural instability. Mixers are sealed by lateral plates ( FIG. 1-I , FIG. 4-I ), which allow to maintain the tightness required to ensure that only the gas passes through the perforations in the upper section of the rectangular base and not dispersed.
  • FIG. 1-J , FIG. 2-J , FIG. 3-J , FIG. 4-J On top of the two external mixers, extending along its length, there are two stainless steel deflectors so that the combustion system will have a front and a rear deflector ( FIG. 1-J , FIG. 2-J , FIG. 3-J , FIG. 4-J ). Said deflectors are composed by a flange of 7 mm, with an angle opt approximately 90 degrees, which is broken in its central zone, generating a bottom angle ( FIG. 1-K , FIG. 2-K , FIG. 3-K , FIG. 4-K ). The presence of deflectors makes easier the cold start, thus preventing the gas to go down to the injectors. The from injector smaller to allow the assembly of the spark plugs.
  • FIG. 1-L , FIG. 2-L , FIG. 3-L , FIG. 4-L a support of spark plugs is assembled ( FIG. 1-L , FIG. 2-L , FIG. 3-L , FIG. 4-L ).
  • Said support is composed by a rectangular shape, which is assembled to the mixer through two lateral flanges and it has along its upper and lower edge, a flange quartered.
  • the cavities which are derived from these sections house the spark plugs ( FIG. 4-R ), which are secured by an additional part of the support ( FIG. 4-S ).
  • This spark plug system composes the flame sensor, which, at the time when the flame goes out, turns off the gas supply, increasing thereby the equipment security.
  • the spark plugs are powered by batteries.
  • the combustion system thus described is secured to the casing of the continuous flow heater which attenuates the effect of altitude by fastening brackets, which lie at the back of the combustion system, at the height of the rear deflector ( FIG. 1-O , FIG. 2-O , FIG. 3-O ).
  • These mounting brackets besides attaching the fuel system to the casing, have a shape that fits the side and upper limbs of the four mixers ( FIG. 1-T ), supporting them, but at the same time ensuring that they are always an equal and calculated distance to each other. Indeed, the mixers are located at the same distance from each other to allow uniform combustion.
  • the heat transfer system essentially comprises three main parts: a rectangular and hollow inside heat exchanger, ( FIG. 4-U ), a diffuser ( FIG. 4-V ) and smoke evacuation duct ( FIG. 4-W ).
  • a serpentine is disposed which contains water ( FIG. 4-X ).
  • the heat exchanger has dimensions which ensure proper assembly with the diffuser, causing a seal to prevent leakage of heat to the environment.
  • the diffuser retains warm air flow to improve heat transfer to the water, prevents the income of external air flow that may affect the combustion system and distributes the evacuation of hot gases into the air exhaust duct in which these hot gases are channeled to the outside of the installation site, improving the quality of the air inside the enclosure and the overall safety.
  • the back casing is the support for all parts of the heater, on top of it the vast majority of components are assembled and it is subsequently secured in the location of final use. It has several mechanical pressed to improve its structural rigidity and its contour delimits the assembly area to the product structure.
  • the casing is a single piece with several manufacturing processes (cutting, punching, stamping, painting) covering the structural and functional systems of the product.
  • the heater turns off the flow of gas to the main burner if any of the following situations occur.
