Definitions
- the present invention relates to a boiler for a machine for preparing hot drinks capable of heating a fluid brought to a relatively high pressure. It will find its particular application for boilers of coffee machines.
- boilers for hot beverage preparation machine comprise a metal block defining a heating chamber and inside which is embedded a resistive element. These boilers have the disadvantage of having a high thermal inertia and require a relatively long time to heat the liquid. Moreover, the obtaining of these boilers induces a significant cost of material. In order to obtain a hot drink in a short time, it has been proposed boilers capable of rapidly raising the temperature of a liquid for the preparation of a drink. These boilers usually comprise a screen-printed resistance heater element associated with a diffuser.
- boilers are however not used for the preparation of drinks requiring substantial pressurization of the liquid. Indeed, they do not withstand relatively high pressures greater than about 8 bar while keeping a small footprint and a limited cost. However, the preparation of certain drinks such as espresso coffee requires the liquid to be brought to a pressure of about 16 bar for the extraction of coffee.
- the present invention aims to satisfy this need.
- the invention provides a boiler for beverage preparation machine comprising at least one diffuser having a first wall intended to be disposed in contact with the fluid to be heated, a second wall opposite the first wall and provided with at least one a heating element, at least one body defining with the first wall of the diffuser at least one heating chamber, wherein the heating element is a screen-printed or photo-etched resistance or any other resistive film.
- the boiler comprises support means arranged to bear on at least a portion of the periphery of the second wall.
- the boiler has a deformation chamber. The boiler is arranged so that in operation, under the effect of the pressure prevailing in the heating chamber, typically between 8 and 25 bar, the diffuser is elastically deformed in the deformation chamber to partially absorb at least the pressure effort.
- the invention allows elastic deformation and penetration of the diffuser within the deformation chamber under the effect of pressure.
- the pressure force is therefore not transmitted, at least in total, to an organ of the boiler, thereby avoiding creating a strong stress zone.
- the diffuser thus absorbs a substantial part of the pressure force generated by the fluid under pressure.
- the diffuser does not need to have a high rigidity or a large thickness. Its thermal inertia is therefore limited.
- the invention thus proposes a boiler resistant to high pressure, typically at least 8 bars, while allowing a reduced heating time.
- the invention may have any of the following characteristics: the boiler is designed to withstand a fluid pressure in the boiler which is easily greater than 10 bar and preferably up to 25 bar in the chamber of heating.

- the diffuser and the deformation chamber are shaped so that the diffuser deforms without interfering with a body of the boiler.
- the diffuser comes into contact with a fluid or a compressible material, such as a gas or an elastomer.
- a fluid or a compressible material such as a gas or an elastomer.
- the diffuser can deform freely in a first phase so as to take up part of the pressure force, and then, in a second phase, to come into contact with a part of the boiler to which it is transmitting part of the residual pressure force.

- the diffuser has a thickness of between 0.3 and 4 mm and more advantageously between 0.5 and 2.5 mm.
- this thickness is between 0.5 and 1.5 mm.
- the deformation chamber in the zone of maximum deformation of the diffusor, is in a diameter of 0.3 and 2 ⁇ m and more advantageously between 0.3 and 1 mm.
- the surface of the diffuser which is free to deform under the effect of the pressure represents more than 60% and advantageously more than 70% and more preferably more than 80% of the total surface of the diffuser.
- the remaining surface is held by the support means and defines the periphery of the diffuser.
- the deformation chamber has an area of between 60 and 95% of the surface of the diffuser.
- the device comprises a support serving as a frame and receiving the support means.
- the support means define the support.
- the support is distinct from the support means.
- the support has a cavity defining the deformation chamber.

- the boiler comprises at least two diffusers mutually facing each other and enclosing the support means.
- the heating chamber is located at the periphery of the heating means and the heating means are located at the periphery of the support means.
- the heating means are located at the periphery of the heating volume and the support means are located at the periphery of the heating means so as to wrap the latter.
- the diffuser is substantially flat.
- the invention is particularly advantageous with this type of diffuser since their pressure resistance is generally very limited.
- the heating means have a substantially cylindrical shape. It can then be provided that the section of the diffusers along the axis of the cylinder is substantially circular or that the section of the diffusers along the axis of the cylinder has a substantially polygonal shape and preferably square.
- the support has at least one first zone in which the support means are located and which is intended to receive the diffuser and at least one second zone situated at the periphery of the first zone and through which the body is intended to be secured to the support.
- the support has a symmetry with respect to a median plane
- the boiler has a symmetry with respect to a median plane.
- the support means are interposed between the second walls of each of the diffusers.
- the invention also relates to a beverage preparation machine such as a coffee machine comprising a boiler according to any one of previous characteristics.
- This machine includes a pump for raising the pressure of the liquid before it is introduced into the boiler.
- FIG. 1 is a sectional view a boiler according to an exemplary embodiment of the invention wherein the diffuser is not subjected to a large pressure force.
- Figure 2 is a boiler sectional view illustrated in Figure 1 in which the diffuser is subjected to a large pressure force.
- the boiler comprises a body 5 and heating means forming with the body 5 a heating volume inside which a liquid is intended to flow and be heated. More particularly, the heating means comprise at least one diffuser 1 having a first wall 2 intended to be arranged in contact with the liquid to be heated. This first wall 2 is intended to bear against an inner face of the body 5 to define the heating chamber.
- the heating volume defines a circulation channel 6 in the form of a coil.
- This channel 6 seen in section has for example two transverse walls and two side walls.
- a first transverse wall 2 is carried by the first wall 2 of the diffuser 1 and a second transverse wall 3 is carried by the internal face of the body 5.
- the lateral walls are carried by the body 5 and extend towards the diffuser 1.
- the channel is cut in the direction of its length.
- the side walls are carried by the diffuser 1.
- the diffuser 1 comprises more material than in the previous variant.
- the side walls increase the contact area between the diffuser 1 and the liquid. Thermal exchanges are therefore favored.
- the heating means comprise at least one heating element disposed on a second wall 3 of the diffuser 1, this second wall 3 being opposite the first wall 2.
- this heating element is a resistive film having a high power density. It is for example obtained by screen printing or photogravure from a resistive ink. It can be thick film type, usually referred to as "Thick Film” or be printed circuit type. This heating element is suitable for FTH (Flow) type boilers
- the silkscreened resistor has at least one track forming a pattern on the second wall 3.
- the resistor comprises a screen printed track or a plurality of tracks defining the pattern. This pattern may for example form a coil, a spiral, a set of concentric circles or juxtaposed or all other forms.
- the screen-printed resistance When the screen-printed resistance is supplied with electricity, it produces heat which is transmitted to the diffuser 1 and then to the liquid occupying the heating chamber.
- the heating chamber forms a circulation channel and the boiler object of the present invention is of the type "Flow Through Heater" whose definition was given above.
- the screen-printed resistance may for example have a thermal power of between 1300 watts and 2500 watts, and more particularly of the order of 1800 to 2200 watts.
- the diffuser 1 serves to serve as a substrate for receiving the screen-printed resistance and to ensure good thermal diffusivity between the screen-printed resistance and the liquid.
- the first wall 2 is coated with a food coating.
- the boiler comprises support means 8 arranged to bear on the second wall 3 of the diffuser 1. These support means 8 tend to keep the diffuser 1 in contact with the body 5.
- the boiler comprises a deformation chamber 7. This chamber is located relative to the heating chamber behind the second wall 3 of the diffuser 1.
- the boiler is arranged so that under the effect of the pressure force generated by the fluid present in the heating chamber, the diffuser 1 is deformed elastically in the deformation chamber 7.
- the boiler is configured so that this deformation of the diffuser 1 absorbs all or at least a significant part of the pressure force. This deformation is essentially static. It occurs with the increase in pressure in the boiler. It freezes then. When the pressure decreases, the diffuser returns to its original shape and position.
- the deformation of the diffuser 1 is illustrated in FIG. 2. In this figure the diffuser 1 forms a plate which flexes while penetrating into the deformation chamber 7.
- the boiler thus makes it possible to accept high pressures without the need for a diffuser 1 which is particularly rigid or has a large thickness.
- the invention thus makes it possible to limit the thickness and therefore the inertia of the diffuser 1. It therefore makes it possible to obtain hot water under pressure in a short time.
- the thermal inertia of the boiler being reduced the efficiency of the latter is also improved.
- the diffuser 1 has a thermal conductivity greater than or equal to 10 W / m / K and more particularly a thermal conductivity of between 10 W / m / K and 400 W / m / K.
- This choice of diffuser 1 makes it possible to promote the transmission of heat between the resistor and the liquid.
- the invention makes it possible to dispense with complex and bulky device for taking up the forces applied to the diffuser 1 to withstand the pressure.
- the invention thus has the advantage of limiting the size of the boiler.
- the depth of the boiler will be adapted so as to allow a deformation of the diffuser 1 which is large enough to absorb at least a significant part of the pressure force.
- the depth of the deformation chamber 7 generally designates the dimension of this chamber in a direction substantially normal to the diffuser 1.
- the deformation chamber 7 is also shaped so that when the diffuser is deformed, the heating element does not interfere with the walls of the deformation chamber 7.
- the heating element is a screen-printed resistance of which the tracks are arranged opposite the deformation chamber 7, a depth of the deformation chamber 7 is provided so as to avoid any electrical contact.
- the deformation chamber 7 limits the transmission of heat by conduction between the diffuser 1 and other organs of the boiler.
- the invention therefore reinforces the thermal insulation of the diffuser 1. The efficiency of the boiler is thus improved.
- a diffuser 1 having good elasticity, especially in bending and good thermal diffusivity.
- a diffuser 1 consisting essentially of metal: steel, stainless steel, aluminum, enamelled steel or brass-based alloy.
- the deformation chamber 7 and the diffuser 1 are shaped so that the diffuser 1 is deformed freely in the deformation chamber 7 without interfering with a part of the boiler which has a rigidity greater than that of the diffuser 1. The latter then absorbs substantially all the pressure force.
- the diffuser 1 does not interfere with any part of the boiler when it penetrates and deforms elastically in the diffusion chamber.
- the diffusion chamber can be filled with unconfined air in the latter. The thermal insulation of the hot parts of the boiler is then improved and the overall efficiency is increased.
- the diffuser 1 interferes with a compressible element disposed in the deformation chamber 7.
- This element may be a gas confined in the chamber made substantially watertight or an elastomer type material such as silicone or rubber resistant to high temperature and / or provided with an insulating coating on its face with respect to the heating elements etc.
- This last variant makes it possible to distribute the pressure force evenly over the diffuser 1. It does not prevent the deformation of the latter so that the diffuser 1 absorbs a largely majority share of the pressure force.
- the compressible element absorbs meanwhile the residual portion of the pressure force that is not absorbed by the diffuser 1.
- This variant has an advantage in terms of safety since any risk of deformation of the diffuser 1 beyond its threshold elasticity is avoided.
- the boiler is arranged so that the diffuser 1 deforms elastically inside the deformation chamber 7 thus containing a substantial part of the pressure force, until it comes into contact with a rigid element whose rigidity is greater than that of the diffuser 1.
- the diffuser 1 then transmits to this rigid element the residual portion of the pressure force not absorbed by the diffuser 1. This residual portion is significantly less than the portion absorbed by the diffuser 1.
- a thermally and electrically insulating material will preferably be chosen.
- the depth of the deformation chamber 7 will be determined as a function, in particular, of the pressure force generated by the fluid and the rigidity of the diffuser 1.
- the boiler is arranged so that when the pressure force is removed, the diffuser 1 finds by elasticity its rest position.
- the support means 8 define a contact on the periphery of the second wall 3 of the diffuser 1.
- the support means 8 can apply a continuous or discontinuous contact in the form of, for example, a plurality of point contacts on the diffuser 1.
- the surface of the diffuser 1 in contact with the support means 8 is less than 40% and advantageously 30% and even more advantageously 20% of the total surface of the diffuser 1.
- the surface of the diffuser 1 which is free to deform to accommodate the pressure force is much larger than the surface of the diffuser 1 held in contact with the body 5 by the support means 8.
- the boiler comprises a peripheral seal 9 interposed between the body 5 and the diffuser 1.
- This seal 9 surrounds the heating chamber so as to seal the latter.
- a groove is provided in the body 5 and inside which is partially housed the seal 9.
- the diffuser 1 is mounted on the body 5, the support means 8 ensure a permanent contact between the seal 9 device and the diffuser 1.
- the seal 9 thus remains, regardless of the pressure of the fluid applied to the diffuser 1, in contact with the latter and the body 5 thus continuously sealing the heating chamber.
- the deformation chamber 7 comprises the heating element. She is isolated from the water.
- the diffuser 1 is shaped so that even deformed, the contact between the seal 9 and the diffuser 1 is not broken or not tampered with.
- the contact between the support 10 and the first wall 2 of the diffuser 1 is also preserved during the deformation.
- a diffuser 1 sufficiently flexible to deform by marrying the walls of the flange 4 and the support 10 without lifting.
- the complementary shapes of the body 5 and the support 4 are also arranged to maintain this contact.
- support means 8 are provided, the dimensions of which are sufficient to ensure that the diffuser 1 is properly held.
- the relief defined by the groove and turned towards the deformation chamber contributes to keep the diffuser pressed against the support means 8 of the body 5 on the one hand and against the support 4 of other by.
- the boiler is thus arranged so that even under a high pressure prevailing inside the heating chamber 6, the insulation of the heating chamber 6 and the insulation of the deformation chamber 7 are preserved.
- the electrical components of the heating element are therefore electrically isolated from the fluid irrespective of the phase of use.
- the boiler comprises a support 10 in which the deformation chamber 7 is defined.
- the support 10 incorporates the support means 8.
- the support means 8 are independent of the support 10 and cooperate with the latter.
- the support means 8 are arranged so that the pressure force exerted on the diffuser 1 by the fluid is not, or is only slightly transmitted to the support means 8. Thus most of the pressure force is applied to the surface of the diffuser 1 intended to be deformed.
- the support means 8 are disposed at the periphery of the surface of the diffuser 1 defining the heating chamber.
- the boiler comprises force recovery means 11 arranged to cooperate with the support means 8 and with the body 5 so as to ensure good transmission of the plating force of the diffuser 1 on the body 5 at the level of support means 8.
- the support 10 incorporates these effort recovery means 1 1.
- the body 5 incorporates the force recovery means 1 1.
- the force recovery means 11 are independent of the support 10 and the body 5 and are arranged to cooperate with the latter.
- the deformation chamber 7 is closed while being sealed. In such an embodiment as illustrated, it is then not possible to access the diffuser 1 by the deformation chamber 7.
- the deformation chamber 7 may be partially or completely perforated, thus creating a passage to access the diffuser 1.
- the diffuser 1 may have a plate shape.
- the invention is particularly advantageous for these types of diffuser 1 since the resistance to pressure of a plate is relatively low. It is also possible that the diffuser 1 has substantially a cylinder shape or cylinder portion.
- the deformation chamber 7 can then also have a cylinder shape or cylinder portion.
- the boiler comprises two diffusers 1, each of the second walls 3 of which are facing each other.
- Each diffuser 1 is associated with a body 5.
- the diffusers 1 define heating chambers which constitute a common assembly defining the same heating volume.
- Each of the second walls has at least one screen printed resistance.
- the screen printed resistances are enveloped by the heating volume.
- the latter is disposed on either side of the assembly formed by the diffusers 1. Consequently, heat transfer between the boiler and its environment are reduced and the thermal efficiency of the boiler is improved.
- the boiler comprises a support 9 common to the two diffusers 1.
- This support 10 defines two deformation chambers turned respectively towards the second wall 3 of one of the diffusers 1.
- the support 10 comprises two peripheral zones disposed respectively at the periphery of one of the deformation chambers. These peripheral zones form support means 8 intended to bear on the second wall 3 of each of the diffusers 1 to press them against the body 5.
- the peripheral zones of the support 10 are also intended to cooperate with the body 5 to ensure proper positioning of the latter relative to the support 10.
- the body 5 consists of two flanges 4 each intended to be associated with a diffuser 1 to set the heating volume.
- Each flange 4 has an outer face and an inner face whose periphery bears on the peripheral zone of the support 10. It is preferably made of plastic.
- the boiler comprises removable fixing means arranged to allow removable attachment and disengagement of the flange 4 on the support 9.
- a boiler according to the example described above has the following characteristics! - Diffuser about 60 cm 2 and 1 mm thick
- the deformation chamber has an area between 75% and 85% of the surface of the diffuser.
- a boiler can easily be used to carry 8 cm3 of water from 20 0 C to 95 0 C in less than 2 seconds.
- diffuser 1 and deformation chamber 7 allow to obtain a good flow of hot water under pressure, in a very short time. These dimensions allow to maintain a limited space while ensuring a good resistance to pressure. Indeed, with this boiler configuration excessive depth of the deformation chambers weakens the robustness of the assembly.
- the support 10 comprises fluidic connection means arranged to ensure an arrival of the liquid in the heating volume and an outlet of the liquid out of the heating volume.
- the boiler comprises electrical connection means arranged to come into contact with complementary electrical connection means connected to the beverage preparation machine in order to supply electricity to the boiler and in particular the heating elements.
- the body is cylindrical, of circular or polygonal section.
- the diffusers are housed inside the body. They are substantially cylindrical and have a section substantially complementary to that of the body. Thus, the body serves as a sleeve around the diffusers.
- the heating volume is located on both sides of the diffusers and envelops the screen-printed resistance.
- the boiler has a single heating chamber. It can then be equipped with only one flat or curved diffuser. Only one deformation chamber is sufficient.
- a boiler may be substantially similar to a boiler half illustrated in Figures 1 and 2, half of which is defined by a section on a plane normal to the plane of the sheet and passing through the middle of the illustrated boiler.
- the same diffuser can receive one or more screen printed resistors
- the side walls of the channel may be carried either by the diffuser or by the body.
- the sealing means comprise two seals of substantially identical section to that of the diffuser and arranged along the axis of the cylinder on either side of the heating chambers.
- a boiler according to the invention has diffusers whose thickness and very low. They use a small amount of metal. The invention thus makes it possible to limit the weight of the boiler and decreases material and transport costs induced by the use of metal. But the cost of transport is particularly important in an eco-design context since the boiler is intended to be separated from the rest of the device to be sent to a maintenance center during its lifetime. In addition, the thermal inertia of the boiler is considerably limited.
