Definitions
- the present invention relates to a steam generator and more particularly a steam generator for domestic appliances such as irons or steam cleaners for example.
- a steam generator comprising a hollow body having a flange surrounding its opening in which is embedded at least one heating body whose ends to be connected to a source of electrical energy emerge from this body, this body further comprising a cover tightly fixed to the flange, by through a joint.
- the present invention relates to a steam generator tending to obviate the aforementioned drawbacks.
- the object of the present invention is the inexpensive realization of a reliable, durable, easily scalable and high quality steam generator especially as regards its lifespan and its possibilities for adjusting the power delivered to the heater. Another object of the present invention is prevent the heating element from coming into contact with the water contained in the watertight container.
- This steam generator is distinguished by the characteristics listed in claim 1.
- the attached drawing illustrates schematically and by way of example a shape of the steam generator according to the invention.
- Figure 1 is a perspective view of the steam generator.
- FIG. 2 is an enlarged end view of the generator steam.
- FIG. 3 is a view in longitudinal section on a larger scale of the steam generator.
- Figure 4 is a side elevational view of the generator tank steam.
- FIG. 5 is a view from A of the tank illustrated in FIG. 4.
- Figure 6 is a perspective view of the steam generator tank.
- Figures 7 and 8 illustrate in perspective an assembly formed of the tank and two heaters.
- Figures 9 to 12 illustrate all of Figures 7 and 8 in plan below, in elevation and at the bottom side respectively opening side of the tank.
- Figure 13 illustrates in perspective the solid aluminum body of the steam generator.
- Figure 14 is a longitudinal section of this solid aluminum body.
- FIG. 15 is an end view, seen from the bottom, of the solid body in aluminum.
- Figure 16 is a perspective view of the flange or cover in aluminum.
- FIG. 17 is a plan view of this cover.
- Figure 18 is a section along line A-A of Figure 17.
- the steam generator illustrated has a solid hollow body made of injected aluminum 1 in the mass of which one or two heating bodies are embedded 2.3, the ends of which must be connected to a source of electrical energy emerging from the open front face of the body 1 in a part of it forming a circular flange 4.
- This flange 4 of the body 1 also has means for fixing a cover 5, here studs 6 embedded in the mass of the body 1.
- the fixing means may be constituted by tapped holes cooperating with screws or by non-tapped holes cooperating with self-tapping screws.
- This massive body 1 made of injected cast aluminum is shrunk by its mode of manufacture on a tank 7 in stamped stainless steel.
- This tank 7 presents a circular or oval flared opening slightly set back from the front flange 4 and recesses allowing the positioning of the heating bodies 2.3 before injection of the aluminum mass.
- the tank 7 and the bodies of heaters 2,3 are positioned as well as the studs 6, in their relative position illustrated in Figures 8 to 11, on the movable core of a mold.
- This mold in two parts are then closed on the core and the cast aluminum is injected into said mold. In doing so, the cast aluminum completely surrounds the heaters. 2,3 and ensures by shrinking or cooling its shrinking on the steel tank 7 stainless.
- We must of course preheat the tank 7 before injecting the cast iron of aluminum and determine the dimensions both of the mold and of this tank 7 for that the finished assembly ensures perfect plating of the tank 7 against the mass aluminum body 1 at the operating temperature of the generator steam, around 140 ° C, while avoiding excessive tension on the steel tank 7 stainless.
- This produces a monolithic assembly allowing excellent heat transmission and total protection of the heating elements 2.3.
- the presence of the stainless steel tank 7 gives this steam generator a much better quality, longevity and descaling possibilities.
- the heating elements 2,3 are completely embedded in body 1 made of cast aluminum and are therefore never contact with water.
- the tightness of the tank 7 is done, as we will see more far away, on a diameter smaller than that on which the ends of the heating element 2,3 emerging from the flange 4, there are no sealed passages at provide for these heaters which also reduces the price and increases the reliability of the steam generator.
- the body 1 in solid aluminum still includes housings, injection, 8.9 intended to receive temperature sensors which are connected to the steam generator control.
- This body 1 is covered with an insulating sleeve (not shown) to avoid heat loss and users to burn themselves.
- the tank 7 made of stainless steel is slightly offset from the body 1 of injected aluminum.
- the body aluminum mass 1 is larger around the bodies of heats 2,3 which ensures greater thermal inertia favorable to the regulation of the steam generator.
- This steam generator also has a cover 10 made of aluminum injected or made of stainless steel fitting on the free face of the flange 4 of the body 1 and fixed to the latter by means of bolts 11 screwed onto the studs 6 of the body 1.
- the inner face of this cover 10 has a circular groove 12 intended to receive an O-ring seal (not shown).
- the cover 10 Apart from the five holes evenly distributed around its perimeter, giving passage to the studs 6, the cover 10 still has several holes threaded for connections or for fixing control elements or security.
- the hole 13 is intended to be connected to a water outlet conduit during a tank descaling cycle.
- the hole 14 is intended to be connected to a cold water inlet pump.
- This hole is provided with a tube (not illustrated), usually a flexible silicone tube, extending inside the tank 7 until near the bottom of it. So during the descaling cycle automatic, the descaling mixture entering this tube must sweep the entire internal surface of the tank 7 before being evacuated by the bore 13.
- the hole 15 is intended to be connected to a steam exhaust duct produced.
- the hole 16 is used to fix a pressure limiting safety valve maximum inside the steam generator.
- the hole 17 serves to fix a relief valve allowing the penetration of air inside the steam generator when the pressure inside it drops below with a pre-established value, generally 1 bar.
- the central hole 18 is used to fixing a probe detecting the water level in the steam generator by through an angular sensor introduced into a float. Such a mechanical sensor is reliable and resistant to scaling.
- This cover 10 naturally also includes holes 19.20 giving passage to the ends of the heating bodies 2.3 in front be electrically connected.
- Another advantage of the generator described is its versatility. When he is used with a steam cleaner that requires a high flow of water vapor two heaters 2,3 are supplied to obtain a power of maximum heating. However, if the generator is used with an iron or a vacuum motor requiring less steam flow, only one heating body is supplied. In this case using a device power supply identical to that used by the steam cleaner the remaining power available can be used for heating the iron.
- this steam generator allows its reliability, its optimization and its versatility. Indeed, due to the fact that the heaters are embedded in the body, these are no longer subject to scaling. Of more, the electrical supply of these heaters no longer requires sealed passage. Finally, the mass of the injected aluminum body is greater in the region where the heaters are embedded, which increases the inertia thermal and facilitates the regulation of the heating bodies.
- Providing a relief valve ensures stability set parameters, such as the generator water level during its which in turn allows for better optimization of the steam generator control.
