HEATING CHAMBER ASSEMBLY

Description

1 / 10 “HEATING CHAMBER ASSEMBLY”. Field of application

[001] This is a set of heating chambers framed within the industrial sector of internal components that are integral to showers, showerheads, electric taps and similar equipment. Fundamentals

[002] In the operational field in question, heating chambers are commonly used in electric showers in order to act basically as converter blocks for the passage of water around a resistance, causing the fluid to be immediately heated and directed by gravity and / or pressure to the perforated bowl(s) of the shower outlet(s) for bathing and similar tasks. Inconveniences observed

[003] Despite the existence of a wide variety of heating chambers applicable in this market niche, it is known that they are usually designed and developed for use in specific shower models, some of which have the problem of radiating a lot of current leakage, lacking adequate encapsulation, not being modular, and being overly complex, especially when replacement is necessary.

State of the art

[004] In order to assist and clarify the state of the art, some surveys were carried out which pointed to the existence of patent documents dealing with relatively similar solutions, but lacking the intrinsic characteristics of the object of the patent application in question, such as the processes listed below, by way of example: - BRMU8400940, relating to a constructive arrangement applied to the heating chamber of electric instantaneous water heating devices through a duct extendable to a wall and at a distance appropriate to the free obstruction of the flow of water at adequate pressure to activate an electric switch, being forced, in addition to the conventional direction, in the radial and perimeter direction in the heating chamber by the directional ducts, generating water currents at high speeds, promoting turbulence and greater contact of the water with the resistive element; - BRMU890006, which deals with a chamber Petition 870240108612, dated 12 / 19 / 2024, p. 6 / 28 A 3 / 10 cylindrical heating element for showers or showerheads, distinguished by having a central compartment that houses the heating element, and another peripheral compartment that receives the water overflowing from the central compartment, which is then evenly distributed to the spray pattern through the base holes; - BR102022009983, featuring an electric water heating device with a cooling chamber for contacts such as electric showers, showerheads, and faucets, consisting of a body with a cold water inlet and a heated water outlet strainer, internally housing the water heating element and an electromechanical drive device that provides energization to said heating element, with the cold water inlet connected directly to a cooling chamber from where it is distributed to thermal pins electrically and mechanically connected to the terminals of the electromechanical drive device.

[005] In the case of the object of the application now disclosed, it was conceived, designed and developed in order to provide a heating chamber assembly whose configuration of its elements combined with their respective interconnections and constructive arrangements made it possible to radiate less current leakage, combining Petition 870240108612, dated 12 / 19 / 2024, page 7 / 28 4 / 10 also the versatility of the helical resistance module, which is easy and simplified to inspect or replace, with the aforementioned heating chamber assembly basically consisting of the tubular body, electrical terminals, and the resistance module formed by the spool tower and the helical resistance itself. Construction and functional aspects

[006] The tubular body forms a cylindrical cup with an inverted nozzle, with a threaded bottom cap opposite the raised upper platforms for insertion and securing, in their through slots, the electrical terminals and adjacent to the L-shaped side pads with triangular reinforcement projections, and for fixing inside the shower that interpose the water inlet and outlet nozzles, staggered from each other, as well as the sinusoidal hose for directing the fluid to the pressure chamber assembly (not illustrated), also having internal guide rails for spacing and supporting the resistance module, positioned slightly above the threaded section that allows, between a sealing ring, the rotatable insertion or removal of the threaded plug and with reinforcing fins of the aforementioned threaded bottom cap,whose rotational torque is facilitated by the oblong protruding latches present on the lower edges of the discoid flange with a central rim that is concave on the outside and convex on the inside, above which it remains suspended, Petition 870240108612, dated 12 / 19 / 2024, page 8 / 28 5 / 10 through the internal interlocking cylinders and the electrical terminals, the aforementioned resistance module.

[007] The electrical terminals comprise median and lateral inverted L-shaped terminals, with T-shaped delimiting extensions on the vertical rods that remain inserted in the aforementioned through slots of the raised upper platforms, separately interconnected to the inner terminal in a smaller bent clip with one end in a groove, and to identical and opposite inner clip terminals with extended vertical rods, ending in an oblique section, also with groove ends.

[008] The median inverted L-shaped terminal connects to the inner one in a smaller clip, while the side terminals each connect to those with extended vertical rods, which extend parallel to each other inside the spool tower tube, centered between the sequential and opposing oblong openings, with their clips fitted into the structural elevations in E flanked by the insertion fixing pins in the aforementioned internal fitting cylinders, also assisted by the extreme sliding blades in the internal guide rails of the inverted nozzle cylindrical cup, as well as by the prominent ramp and the rectangular cutout present in the upper floor of the spool tower, opposed to the circular flanged disc base, interrupted by equally opposing lower cutouts.

[009] The aforementioned spool tower is surrounded by a raised spring outline that begins just below the arched claw-like protrusions and continues through the sequential, opposing, oblong openings, also forming the seating channels for the steps on the inner sides of the helical resistance body formed by intertwined resistive springs, until it ends on the circular flanged disc base.
