Description

[0001] Thermostatic valve and faucet associated

[0002] Technical field

[0003] The present invention relates to the field of fluid valves and in detail concerns a thermostatic valve.

[0004] Introduction

[0005] Thermostatic valves are valves that are configured to cause the adjustment of a fluid flow according to a temperature thereof. Typically, thermostatic valves are configured to determine such adjustment automatically, that is, without the need for operator intervention.

[0006] A thermostatic valve is for example described by document DE 10 2019 103913 A1 ; this valve is designed to overcome the traditional problems of hysteresis and inaccurate switching typical of traditional valves, and is designed for applications in cooling circuits of a vehicle or for fluid and / or ambient temperature controls.

[0007] Adjustable thermostatic valves are also known; these valves have fluid flow adjustment features, and these features are a function of a temperature threshold that is adjustable by the user.

[0008] Also known are faucets configured to dispense conditioned water, and in particular configured to dispense at least water over a first temperature range excluding so-called boiling water (first conditioning), and to dispense - as an alternative - water at a higher temperature than the first range, i.e. , so-called boiling water (second conditioning).

[0157] Detailed description

[0158] Reference number 1 identifies a thermostatic valve.

[0159] In a preferred embodiment, thermostatic valve 1 comprises an outer body 2, 6 which in turn comprises a lateral body 2 and an inlet body 6. At least one between the lateral body 2 and the inlet body 6 can be realized in metallic material, or in plastic material.

[0160] The thermostatic valve 1 comprises an inlet 3 and an outlet 4i, 4o for a fluid, preferably conditioned water.

[0161] The lateral body 2 is a substantially tub-shaped body, and when insulated from the other components of the valve described herein (see, for example, the exploded view in Figure 5), identifies an upper opening and a lower opening and a lateral wall which joins between the upper opening and the lower opening The lateral body 2 comprises an ending portion, which is connected to the lower opening and which ends, inferiorly, with the outlet 4i, 4o of the thermostatic valve 1

[0162] When coupled between them in the operating configuration, the lateral body 2 and the inlet body 6, except for the inlet 3 and the outlet 4i, 4o, are liquid-tight

[0163] In the operating configuration, the inlet body and the lateral body are joined together and are fixed with respect to each other.

[0164] The thermostatic valve 1 comprises a thermostatic adjustment group 5, 7, 8, positioned within the outer body 2, 6. The thermostatic adjustment group 5, 7, 8 comprises at least one flow diverting body 5, which is movable with respect to the outer body 2, 6.

[0165] The thermostatic adjustment group 5, 7, 8 also comprises a first elastic element 7, which is destined to determine the movement of the thermostatic adjustment group 5, 7, 8 according to the temperature of the inlet fluid.

[0166] The first elastic element 7 possesses a variable size and / or deformation force F according to a temperature taken by the fluid.

[0167] The flow diverting body 5 of the thermostatic adjustment group 5, 7, 8 has a first position with respect to said outer body 2, 6 and a second position with respect to said outer body 2, 6. It can therefore be asserted that at least one part of the thermostatic adjustment group 5, 7, 8 can move between a first position with respect to said outer body 2, 6 and a second position with respect to said outer body 2, 6 and / or vary its own shape as a result of the movement between said first position and said second position.

[0168] As clearly visible in the sections of figure 3 and 4, for example, the flow diverting body 5 identifies a substantially U-shaped, downward-facing structure that identifies a first opening and a second opening and that also identifies a central hole, defined in particular between the first opening and the second opening and within which, in use, the fluid flows.

[0169] The first opening is substantially opposed with respect to the second opening. The first opening is axially aligned to the second opening, and in particular both openings are aligned on an axis of movement of the flow diverting body (axis X). This does not exclude that further embodiments of the valve object of the present disclosure, not shown in the attached figures, can have the first opening not axially aligned to the second opening.

[0170] The first opening is facing the inlet 3, while the second opening is facing the outlet 4i, 4o. The first opening has an area that is greater than the area of the second opening. Clearly that area is calculated with the flow diverting body 5 deprived of elements introduced in the first and second opening.

[0171] The outlet 4i, 4o, as a whole, can have an area (orthogonal transversal section with respect to the axis of movement of the flow diverting body) greater with respect to the area of the inlet 3, or - alternatively - have a smaller area with respect to the latter.

[0172] The assembly formed by the thermostatic adjustment group 5, 7, 8 and by the outer body 2, 6 identifies a second channel 10 and a first channel 11 , arranged in correspondence of said thermostatic adjustment group 5, 7, 8.

[0173] The first and second channel 10, 11 allow, alternatively or in combination, a flow of said fluid between the inlet 3 and the outlet 4i, 4o.

[0174] In said first position, the flow adjusting body 5 of the thermostatic adjustment group 5, 7, 8 allows the flow of the fluid in said first channel 11 .

[0175] In said second position, the flow adjusting body 5 of the thermostatic adjustment group 5, 7, 8 allows the flow of the fluid in said second channel 10, or in said second channel 10 and in said first channel 11. In particular, in the shown embodiments, in said second position the thermostatic adjustment group 5, 7, 8 allows the flow of the fluid in the second channel 10 and in the first channel 11 .

[0176] The inlet body 6 comprises:

[0177] - a feeding portion 6f, which with an inner portion 6i thereof protrudes within a cavity of the flow diverting body 5;

[0178] - a connection portion 6c, connecting with said lateral body 2 and joined to, or extending from, said feeding portion.

[0179] An outer portion of the feeding portion is arranged substantially outside of the lateral body 2.

[0180] The feeding portion 6f identifies a through cavity with a circular transversal section. Although this solution is preferable, it is not excluded that the transversal section can take a different shape, for example ovoid or polygonal.

[0181] The feeding portion 6f extends in a substantially oblique direction, preferably orthogonal, with respect to the connection portion 6c.

[0182] The inner portion 6i, preferably extends along the same direction as the feeding portion. The inner portion 6i represents an extension of the outer portion. The inner portion 6i lies in use within the cavity of the flow diverting body 5. Preferably, the inner portion 6i is arranged along the same direction along which the feeding portion extends, i.e. is parallel to the axis X.

[0183] It thus seems clear that the present disclosure shows an embodiment of a thermostatic valve wherein the outer body 2, 6 comprises at least a portion that is substantially introduced into the flow diverting body 5. In particular, is the inner portion 6i of the inlet body 6, which - in turn - is part of the outer body 2, 6, to be found introduced within the flow diverting body 5.

[0184] In particular, the inner portion 6i of the inlet body 6 is introduced in the first cavity of the flow diverting body 5.

[0185] The inner portion 6i realizes a common part both of the second channel 10 and of the first channel 11 ; in fact, the fluid flows in the inlet body 6 and therefore in the inner portion 6i thereof, both in the first position and in the second position.

[0186] Figures 1 -7 show a particular embodiment wherein the feeding portion 6f, and in particular its outer portion, is provided with engaging elements 6e, such as knurls and / or sawtooth profiles, which facilitate the retention of a duct, in particular deformable e.g. elastically, in particular a duct in plastic material and / or rubber, which in use is fixed outside of the feeding portion, and which is in particular sleeved on the feeding portion.

[0187] In the embodiment shown in figures 1 -7, the feeding portion 6f is axially aligned to the direction of movement, in particular of translation, of the flow diverting body 5, and the connecting portion 6c extends along an oblique direction, preferably orthogonal, with respect to the feeding portion and contacts an inner face of said outer body 2, 6, in particular of the lateral body 2. Clearly, this configuration is not intended to be limiting.

[0188] The inlet body 6 is demountable with respect to the lateral body 2. In particular, the peripheral portion of the connection portion is held in place in a relative recess bounded inferiorly by a step 2s anularly extending along the inner face of the lateral body 2 and, upperly, is held in place by an elastic ring 13 (seeger) locked in a recess 2r of the lateral body, identifying a concavity on the inner lateral part thereof.

[0189] In a radially perimeter position, the connection portion 6c comprises a recess 6k, in particular an annular recess extending seamlessly over the entire circumference identified by it, and within that recess is arranged an O-ring indicated by the reference 6g, which is provided for the purpose of preventing fluid leakage between the lateral body 2, in particular its inner face, and the inlet body 6.

[0190] As it will become clear by reading the following portion of the description, transfer holes present in correspondence of a flow diverting body 5 of the thermostatic adjustment group 5, 7, 8 are moved and / or open or closed determining the opening or closing of the second channel 10. As it will become clear by reading the following portion of the description, the orientation of the transfer holes can be:

[0191] - axially aligned with a movement direction, optionally of translation, of the thermostatic adjustment group 5, 7, 8 with respect to said outer body 2, 6, and thus of the flow diverting body 5 with respect to the outer body 2, 6, in particular with respect to the assembly formed by the lateral body 2 and by the body in inlet 6;

[0192] - axially inclined with respect to a movement direction, optionally of translation, of the thermostatic adjustment group 5, 7, 8 with respect to said outer body 2, 6, and thus of the flow diverting body 5 with respect to the outer body 2, 6, in particular with respect to the assembly formed by the lateral body 2 and by the body in inlet 6.

[0193] In a non-limiting embodiment, the orientation of transfer holes is substantially orthogonal with respect to a movement direction, optionally of translation, of the thermostatic adjustment group 5, 7, 8 with respect to said outer body 2, 6, and thus of the flow diverting body 5 with respect to the outer body 2, 6, in particular with respect to the assembly formed by the lateral body 2 and by the body in inlet 6.

[0194] It is observed that in the embodiment shown in figures 1 -7, the inlet 3 and the outlet 4i, 4o of thermostatic valve 1 are axially aligned.

[0195] Preferably, first channel 11 has a second span determining, in use, a second and smaller flow of fluid; the second channel 10 possesses a first span, and the first span or the assembly of the first span and of the second span, is greater than the second span and determines, in use, a greater flow of fluid.

[0196] In detail, the first span is intended as a minimum span, that is, a minimum transversal section [mm2], of the first channel and the second span is also intended as the minimum transversal section, of the second channel. In other words, the second channel 10 defines, in use, a first flow rate Qi [m3 / h] at equal fluid pressure difference between said inlet 3 and said outlet 4i, 4o. The first channel 11 defines, in use, a second flow rate Q2 [m3 / h] at equal fluid pressure difference between said inlet 3 and said outlet 4i, 4o.

[0197] Therefore:

[0198] - when the thermostatic adjustment group 5, 7, 8 is in the first position, it allows the flow of fluid in said first channel 11 ,

[0199] - when the thermostatic adjustment group 5, 7, 8 is in the second position, it allows the flow of fluid in said second channel 10, which provides, in use, a respective flow rate of fluid greater than the flow rate provided, in use, by the first channel 11 , or allows the flow of said fluid simultaneously in said second channel 10 and in said first channel 11 .

[0200] It thus seems clear that the present disclosure shows a thermostatic valve wherein the outlet 4i, 4o is always open, independently of the position assumed by the thermostatic adjustment group 5, 7, 8, in particular by the flow diverting body 5.

[0201] Thanks to this technical feature is it is possible to dispense water added with carbon dioxide through the first channel 11 with a slow flow to ensure an optimal carbonization, and it is also possible to dispense hot water through the second channel 10 or the combination of the second channel 10 and of the first channel 11 with a higher flow.

[0202] The first channel 11 is radially inside the second channel 10 and is preferably arranged between an outer wall of the flow diverting body 5 and an inner wall of said outer body 2, 6, in particular an inner wall of said lateral body 2. Therefore, it is clear that the present disclosure relates to a thermostatic valve 1 wherein the second channel 10 ed the first channel 11 are axially aligned. The second channel 10 is an annular channel, in particular an outer annular channel.

[0203] In use, the flow of fluid from the inlet 3 to the outlet 4i, 4o of the thermostatic valve 1 identifies a first direction when said fluid transits in said second channel 10, it flows at least partially along a substantially opposite direction with respect to said first direction. As it seems clear from the attached figures, said first direction is substantially coinciding with the movement direction, in particular of translation, of the flow diverting body 5.

[0204] The specific conformation of the inlet body 6 is in fact such that the fluid inlet 3 transits axially along the axis X to arrive within the flow diverting body 5. The part of fluid that does not transit through the dispenser 9, see next part of the description, is diverted laterally along an oblique direction with respect to the X axis and is subsequently conveyed toward the head of the flow diverting body 5 in a portion of the second channel 10 that is bounded laterally (orthogonal direction with respect to the axis X) in the following manner:

[0205] - radially internally, from the outer wall of the inner portion of the inlet body 6,

[0206] - radially externally, from the inner wall of the flow diverting body 5.

[0207] In that portion of the second channel 10 the fluid flow is in a direction opposite with respect to the direction identified by a direction from the inlet 3 to the outlet 4i, 4o.

[0208] In particular, the size and / or deformation force F of at least the first elastic element 7 and, optionally, of the second elastic element 8 determines the movement of the thermostatic adjustment group 5, 7, 8 when the fluid has a temperature T substantially comprised in the range [70-100] °C, preferably [80-100] °C, or preferably [85-100] °C, or [90-100] °C.

[0209] In an embodiment, when the temperature of the fluid reaches a predetermined value, preferably in the range described above, there is an almost immediate switching of the position assumed by the flow diverting body 5. This technical feature, which is the result of the technical features of the first elastic element 7 and / or of the joint action carried out on the flow diverting body 5 by the first elastic element 7 and by the second elastic element 8, is particularly useful where the thermostatic valve 1 object of the present disclosure is used for the dispensing of conditioned water including water added with carbon dioxide and hot water.

[0210] More specifically, the flow diverting body 5 is configured to switch between the first position and the second position substantially immediately, or in a time substantially lower than 3 seconds, or than 2 seconds or than 1 second, when said fluid exceeds, or falls below, at least a predetermined temperature value. In a non-limiting way, said at least a predetermined temperature value is comprised in the range [70-100] °C, preferably [80-100] °C, or preferably [85-100] °C, or [90-100] °C.

[0211] The thermostatic valve described here allows to maintain flexibility in managing distinct fluid flows according to the temperature thereof without the need for operator intervention.

[0212] The first elastic element 7 is a coil spring. Because of the characteristics described above the first elastic element 7 is definable as a shape memory elastic element.

[0213] The first elastic element 7 can, for example, be realized in a metal alloy with a NiTi base, or Cu base, in particular Cu-Zn-AI or Cu-AI-Ni.

[0214] The thermostatic adjustment group 5, 7, 8 comprises a second elastic element 8 that acts in contrast to said first elastic element 7 in the movement of the flow diverting body 5 between said first position and said second position.

[0215] The second elastic element 8 is a coil spring. Preferably, the second elastic element 8 is not of the shape memory type. In any case, preferably also the second elastic element 8 is realized in metallic material, and can be realized with a metal alloy with a NiTi base or Cu base.

[0216] In the embodiments of the attached figures, the first and the second elastic element 7, 8 in the form of a coil spring are characterized by having a first diameter and a second diameter different between them.

[0217] As it can be clearly seen in the section of figure 3 or of figure 4, the inner portion of the inlet body 6 identifies a guide for the second elastic element 8. Preferably such inner portion of the inlet body 6 results in a substantially circular transversal, or truncated cone section, and has a diameter smaller with respect to the diameter taken by the coil spring that realizes the second elastic element 8.

[0218] As clearly visible from the attached figures, the first elastic element 7 and the second elastic element 8 act simultaneously on the flow diverting body 5 so that when said flow diverting body 5 moves, in particular translates, from said first position to said second position, the first elastic element 7 is extended and said second elastic element 8 is compressed, and so that when said flow diverting body 5 moves, in particular translates, from said second position to said first position, the first elastic element 7 is compressed and the second elastic element 8 is extended.

[0219] In the embodiment shown in figures 1 - 7, the first elastic element 7 is arranged coaxially to the movement direction, in particular of translation, and the second elastic element 8 is arranged too coaxially to said movement direction.

[0220] The first elastic element 7 is arranged substantially outside of the flow diverting body 5 and the second elastic element 8 is arranged substantially within the flow diverting body 5.

[0221] As it is possible to observe from the section of figure 3 and / or of figure 4, at least part of the first elastic element 7 and / or at least part of the second elastic element 8 extends above, or below, an upper or lower end, respectively, of a lateral wall of the flow diverting body 5.

[0222] The flow diverting body 5 comprises a head portion identifying a plurality of contact portions 5p, which are destined in use to contact the inner lateral wall of the lateral body 2.

[0223] The contact portions 5p protrude from the lateral wall of the flow diverting body (in this embodiment, substantially cylindrical) toward a radially outer direction. They substantially all lie in correspondence of the head of the flow diverting body 5 and are planarly aligned.

[0224] In particular, between two contiguous contact portions 5p are identified recesses that allow the passage of the fluid into the second channel 10. This technical feature is visible with particular ease in the perspective of figure 2 and in the exploded view of figure 5.

[0225] The contact portions 5p act as strike plates for the first elastic element 7; as it is clearly observable in figures 1 -7, the first elastic element 7 is constrained:

[0226] - in correspondence of a first portion thereof, in particular of a first end thereof, on the flow diverting body 5 and, in particular, on the contact portions 5p;

[0227] - in correspondence of a second portion thereof, in particular of a second end thereof opposed with respect to the first end, against the lateral body 2, and, in particular, against a bottom wall of the lateral body 2. The second elastic element 8 7 is constrained:

[0228] - in correspondence of a first portion thereof, in particular of a first end thereof, on the inlet body 6;

[0229] - in correspondence of a second portion thereof, in particular of a second end thereof opposed with respect to the first end, against the flow diverting body 5.

[0230] More in detail, the first portion, in particular the first end, of the inlet body 6 is constrained on the plate of the inlet body 6 that is realized by the contact portion 6c thereof. This plate extends in a plane substantially orthogonal with respect to the movement direction, in particular of translation, of the flow diverting body 5.

[0231] Clearly, in order to allow the translation of the flow diverting body 5 within the lateral body 2, the inner lateral wall of the lateral body 2 identifies a transversal section substantially of constant diameter along the development axis X of the thermostatic valve 1. This transversal section is substantially cylindrical.

[0232] The reference numbers 4i and 4o indicate an inner portion and an outer portion, respectively, of the outlet 4i, 4o of the thermostatic valve 1 . The fluid flows in the inner portion 4i of the outlet 4i, 4o of the thermostatic valve 1 .

[0233] In an embodiment, the inner portion 4i of the outlet 4i, 4o can have an area available for water passage (transversal section orthogonal with respect to the axis X) greater with respect to the area of the inlet 3. Alternatively, this area can be smaller with respect to the one of the inlet 3.

[0234] Likewise, the area of the outer portion 4o of the outlet 4i, 4o can be greater with respect to the area of the inlet 3 or, in a further embodiment, smaller with respect to the latter.

[0235] In the embodiment shown in figures 1 - 7, the flow diverting body 5 comprises an ending portion in use defining the inner portion 4i of said outlet 4i, 4o; the lateral body 2 comprises an outlet hole and an ending portion connecting the outlet hole with the outlet 4i, 4o of the thermostatic valve 1 .

[0236] The outlet hole is preferably with circular transversal section. It is not excluded that different shapes for the transversal section may characterize the outlet hole. Likewise, the outlet 4i, 4o of thermostatic valve 1 is preferably with circular transversal section. It is not excluded that different shapes for the transversal section can characterize the outlet 4i, 4o of the thermostatic valve 1 .

[0237] Preferably, the ending portion of the flow diverting body 5 is at least partially housed within the outer body 2, 6 and in particular is at least partially housed within the ending portion of the outer body 2, 6.

[0238] This is in particular valid both when the thermostatic adjustment group 5, 7, 8 is in said first position and when said thermostatic adjustment group 5, 7, 8 is in said second position. The outer portion 4o of the outlet 4i, 4o of the thermostatic valve 1 radially surrounds the inner portion 4i. More precisely, the outer portion has a diameter larger than the inner portion.

[0239] In particular, in the embodiment shown in figures 1 -7, the ending portion of the flow diverting body 5 is entirely housed within the outer body 2,6.

[0240] The ending portion of the flow diverting body 5 comprises at least a transversal hole 5k, and preferably a plurality of transversal holes 5k. This at least a transversal hole 5k is configured to open within the cavity identified by the lateral body 2 to allow to place the second channel 10 in communication with said outlet 4i, 4o.

[0241] The transversal hole 5k, or when present the plurality of transversal holes 5k, acts as transfer hole, or plurality of transfer holes.

[0242] In the embodiment shown in figures 1 -7, la transversal hole 5k, or when present the plurality of transversal holes 5k, opens on the inner portion 4i of the outlet 4i, 4o. Therefore in use it allows an adduction of fluid in the inner portion 4i of the outlet 4i, 4o, in particular by adducing a fluid from a direction substantially orthogonal with respect to the axial sliding direction of the thermostatic adjustment group 5, 7, 8 and / or of the flow diverting body 5 with respect to the outer body 2, 6.

[0243] The flow diverting body 5 comprises a dispenser 9, which is introduced within an its own seat realized on the flow diverting body 5, in particular in a base position of the flow diverting body opposed with respect to the head portion of the flow diverting body 5.

[0244] During the assembly the dispenser 9 is installed with a contrasting coupling within the seat, and it is also retained there, for example, by an O-ring. At least a dispensing hole is present on said dispenser 9. Preferably the dispenser 9 comprises a plurality of holes. If present in a plurality, the holes of the dispenser 9 can have the same shape and / or size, or shape and / or size different from each other.

[0245] The dispenser 9 is axially aligned to the outlet 4i, 4o of the thermostatic valve 1 . In the embodiment shown in figures 1 -7, the dispenser 9 is axially aligned too to the inlet 3 of the thermostatic valve 1 .

[0246] The at least one dispensing hole allows, in use, a flow of fluid from the inside of the flow diverting body 5 to the outlet 4i, 4o of the thermostatic valve 1 . The at least a dispensing hole therefore allows the flow of fluid in the second channel.

[0247] When the thermostatic adjustment group 5, 7, 8 is in said first position, said flow diverting body 5 causes, through the dispenser 9, a flow of fluid exclusively within said first channel 11. Thanks to this aspect is it is possible to have a very slow dispensing, and therefore an excellent carbonization of the water dispensed.

[0248] When the thermostatic adjustment group 5, 7, 8 is in said first position, said ending portion of said flow diverting body 5 occludes the outlet hole of the lateral body 2 forcing a flow of fluid along said first channel 11 .

[0249] When the thermostatic adjustment group 5, 7, 8 is in said second position, the flow of fluid is made possible by at least a transversal hole 5k that allows the passage through the second channel 10 towards the outlet.

[0250] In detail figure 3 shows the thermostatic valve 1 in a configuration wherein the thermostatic adjustment group 5, 7, 8 is arranged in the aforementioned first position. As it is possible to observe from figure 3, the position relatively taken between the flow diverting body 5 and the outer body 2 is such that the second channel 10 is closed, since the flow diverting body 5 is in contrast with the outer body 2; the plurality of transversal holes 5k is under the (outside of the) portion of the outer body 2 that realizes the mechanical strike for the flow diverting body 5.

[0251] Figure 4 shows the thermostatic valve 1 in a configuration wherein the thermostatic adjustment group 5, 7, 8 is arranged in the aforementioned second position. As it is possible to observe from figure 3, the portion relatively taken between the flow diverting body 5 and the outer body 2 is such that the second channel 10 is open. The flow diverting body 5 is lifted with respect to the lower portion of the outer body 2 and the plurality of transversal holes 5k is above the (within the) portion of the outer body 2 that realizes the mechanical strike for the flow diverting body 5.

[0252] In the first embodiment, therefore, the transfer holes realized by the plurality of transversal holes 5k move between a substantially inner position (second position) to a substantially outer position (first position) with respect to the chamber identified by the outer body 2.

[0253] In the first embodiment, a part of the inlet body 6, and in particular the inner portion 6i, extends within the second elastic element 8, which is immediately in proximity to an outer surface of the inner portion 6i of the inlet body 6. As it is clear from figure 3, and figure 4, a part of the inlet body 6, and in particular the inner portion 6i, extends within the first elastic element 7. The latter lies outside of a part of the second elastic element 8; it therefore seems clear that in the embodiment shown in figures 3 and 4 a part of the first elastic element 7 lies outside of the second elastic element 8, and therefore the first and the second elastic element 7, 8 have a respective portion that is aligned along a direction orthogonal to the axis X that realizes the common axis along which the first elastic element 7 and the second elastic element 8 move in compression and extension. In other words, the first elastic element 7 and the second elastic element 8 are partially overlapping in the longitudinal direction, and the longitudinal direction is defined by the axis X.

[0254] In particular, the previously mentioned alignment and the partial overlap here described, are present both when the flow diverting body 5 is in the first position, and when the flow diverting body 5 is in the second position.

[0255] A second embodiment of the thermostatic valve 1 object of the present disclosure is shown in figures 8 - 9.

[0256] Also in this case, the thermostatic valve 1 , the thermostatic valve 1 comprises an outer body 2, 6 which in turn comprises a lateral body 2 and an inlet body 6. Again, at least one between the lateral body 2 and the inlet body 6 can be realized in metallic material, or in plastic material.

[0257] In order not to overextend the present description, the thermostatic valve 1 according to this new embodiment it will not be described again in all its common features with the preceding embodiment. Only the different parts will be described below.

[0258] The inlet body 6 comprises:

[0259] - a feeding portion 6f, protruding within a cavity of the lateral body 2;

[0260] - a connection portion 6c, connecting with said lateral body 2 and joined to, or extending from, said feeding portion.

[0261] The connection portion 6c identifies an intermediate chamber 14 whose transversal section is greater with respect to the transversal section of the feeding portion.

[0262] Such intermediate chamber 14 assumes that larger transversal section because, as it will be better clarified below, it is destined to house at least a part of a shape memory first elastic element.

[0263] As in the case of the preceding embodiment, the thermostatic valve 1 comprises a thermostatic adjustment group 5, 7, 8, positioned within the outer body 2, 6. The thermostatic adjustment group 5, 7, 8 comprises at least a flow diverting body 5 and a first elastic element 7, which is destined to determine the movement of the thermostatic group 5, 7, 8 according to the temperature of the inlet fluid.

[0264] The flow diverting body 5 assumes a shape such as a plate, and can possess a central hole 5c and at least a lateral hole 5g, preferably a plurality of lateral holes positioned in correspondence of an outer annular portion of the flow diverting body, and therefore the lateral holes are radially external with respect to the central hole 5g.

[0265] As clearly visible in the sections of figure 8 and 9, the flow diverting body 5 in this case identifies a first opening and a second opening.

[0266] The first opening is substantially opposed with respect to the second opening. The first opening is aligned axially to the second opening, and in particular both openings are aligned on an axis of movement of the flow diverting body.

[0267] The first opening is facing the inlet 3, whereas the second opening is facing the outlet 4i, 4o. The flow diverting body is in this case formed by a first portion and by a second portion, which are at least partially aligned along a direction substantially identified by the axis of movement of the flow diverting body itself.

[0268] The first portion is the one closest to the inlet 3, whereas the second portion is the one closest to the outlet 4i, 4o.

[0269] The first opening is in the first portion, while the second opening is in the second portion.

[0270] The first opening has an area that is smaller than the area of the second opening. Clearly that area is calculated with the flow diverting body 5 deprived of elements introduced in the first and second opening.

[0271] A portion of the flow deviator 5 can comprise a seat 5s suitable for housing at least partially said first elastic element. In particular, in a preferred embodiment such seat is a recess, and it can be of annular type and arranged around the central hole.

[0272] The central hole of the flow deviator 5 extends along a direction substantially parallel to the predefined movement direction, in particular of translation, of the thermostatic adjustment group 5, 7, 8 and in particular in direction substantially parallel to the predefined movement direction, in particular of translation, of the flow diverting body 5.

[0273] Unlike the preceding embodiment, wherein it is present a flow diverting body 5 that comprises the seat for the dispenser, in the embodiment shown in figures 8-10, it is the lateral body 2 that possesses a seat for the dispenser 9.

[0274] In the second embodiment, as clearly visible in figures 8 and 9, a part of the first elastic element 7 lies within the second elastic element 8, and therefore the first and the second elastic element 7, 8 possess a respective portion that is aligned along a direction orthogonal to the axis X that realizes the common axis along which the first elastic element 7 and the second elastic element 8 move in compression and extension. In other words, the first elastic element 7 and the second elastic element 8 are partially overlapping in the longitudinal direction, and the longitudinal direction is defined by the axis X. In particular, the previously mentioned alignment and the partial overlap here described, are present both when the flow diverting body 5 is in the first position, and when the flow diverting body 5 is in the second position.

[0275] Again, the dispenser is positioned in said seat and is provided with at least a dispensing hole that allows in use the flow of the fluid to the outlet.

[0276] As it is clearly observable in the attached figures, the dispenser 9 is for example axially arranged below the flow diverting body 5.

[0277] The dispenser 9 is for example housed within the shape identified by the lateral body 2; however, this spatial configuration should not be intended in a limiting way since in an alternative embodiment the dispenser 9 can protrude with respect to the shape identified by the lateral body 2.

[0278] The thermostatic adjustment group 5, 7, 8, possesses a first position with respect to said outer body 2, 6 and a second position with respect to said outer body 2, 6. The first position is a position wherein the flow diverting body 5 is positioned spaced with respect to said inlet body 6, in particular being axially spaced with respect to the inlet body along a direction substantially parallel to the axis X of the thermostatic valve 1 .

[0279] When in said first position, the flow diverting body 5 is in contact with a striker that is part of the lateral body 2. When in said second position, the flow diverting body 5 is spaced with respect to the striker. Preferably, when in said second position, the flow diverting body 5 is not in direct contact with the inlet body 6.

[0280] In the embodiment shown in figures 8 - 9 the thermostatic valve 1 object of the present disclosure comprises a second channel 10 and a first channel 11 , arranged in correspondence of said thermostatic adjustment group 5, 7, 8, and allowing a flow of said fluid between the inlet 3 and the outlet 4i, 4o.

[0281] The first channel 11 is a channel that develops substantially along a direction axial with the axis X, and in particular in use, in the first channel 11 the fluid follows a path that goes along the direction that joins the inlet 3 con the outlet of the thermostatic valve 1 .

[0282] The second channel 10 is a channel that develops in position radially outer with respect to the position wherein lies the first channel 11 . In use, in the second channel 10 the fluid follows a path at least partially substantially oblique, preferably orthogonal, with respect to the direction taken by the flow of fluid in transit in the first channel 11 .

[0283] Unlike the previously described embodiment, in the second channel 10 the flow typically does not proceed - mainly driven by elements of the valve here described - in direction opposed with respect to the direction identified by the inlet 3 to the outlet 4i of the thermostatic valve 1 .

[0284] The outer body 2 has a support 20 for the dispenser 9, and the second channel 10 is in correspondence of a free annular portion present between the inner face of the lateral body 2 and the support 20 for the dispenser 9, particularly in a free annular position present between the inner face of the lateral body 2 and an outer face of the support 20.

[0285] The embodiment of figures 8 - 10 has a second elastic element 8 that acts in contrast to said first elastic element 7 in the movement of the flow diverting body 5 between said first position and said second position. The second elastic element 8 is a coil spring. Preferably, the second elastic element 8 is not of the shape memory type.

[0286] The second elastic element 8 lies entirely within said second channel 10 and is therefore housed within the free annular portion present between the inner face of the lateral body 2 and the support 20 for the dispenser 9.

[0287] In use, when the flow diverting body 5 is in correspondence of the first position, the flow of fluid occurs both in the second channel 10 and in the first channel 11 . The portion of fluid that flows in the second channel 12 transits axially between the inlet 3 and the outlet 4i of the thermostatic valve 1 passing through the central hole of the flow diverting body 5 and, subsequently, through the dispenser 9 before reaching the outlet 4i of the thermostatic valve 1 .

[0288] The portion of fluid that flows in the second channel 10 when it leaves the intermediate chamber 14 of the inlet body 6 deviates laterally along a nearly orthogonal direction, passes through the at least one or, where present, the lateral holes of the flow diverting body 5 to arrive to assume again a direction substantially parallel to the direction identified by the axis X and join with the outlet 4i of the thermostatic valve 1 skipping the transit through the dispenser 9. Figure 8 shows the thermostatic adjustment group 5, 7, 8 in a first position wherein the flow diverting body 5 is in substantial contact with the inlet body 6, in particular with the contact portion 6c of the inlet body 6. The fluid cannot transit within said at least one lateral hole 5g of the flow diverting body; it flows from the intermediate chamber 14 to the outlet 4i only through the central hole 5c of the flow diverting body. In this configuration, all the fluid flows through the dispenser 9.

[0289] Figure 9 shows the thermostatic adjustment group 5, 7, 8 in a second position wherein the flow diverting body 5 is substantially spaced, in particular axially spaced, with respect to the inlet body 6, and is in particular axially spaced with respect to the contact portion 6c of the inlet body 6. The separation allows a portion of fluid to flow into the at least a lateral hole 5g of the flow diverting body 5; the fluid then flows passing through an annular portion of the outer body 2 that defines the second channel 10.

[0290] It is therefore clear that the at least a lateral hole 5g, optionally the plurality of lateral holes 5g, of the flow diverting body 5, which also in this further embodiment realizes at least a transfer hole, are respectively open or closed to allow the flow of fluid in the second channel 10.

[0291] Figure 10 shows a faucet 100. In a non-limiting embodiment, the faucet 100 can be realized in metallic material, for example, stainless steel and / or brass and / or aluminum or its alloy.

[0292] The faucet 100 comprises a dispensing pipe 104 that can end with a jet breaker or aerator 106 or alternatively end in a free mode for water dispensing.

[0293] The dispensing pipe 104 is configured to house within it a dispensing duct of conditioned water which is indicated with the numerical reference 101 .

[0294] The dispensing pipe 104 identifies an outer duct for fluid, in particular for water, not coming from the dispensing duct 101. This means that between the fluid, in particular water, that flows within the dispensing pipe 104 but outside of the dispensing duct 101 , and that which flows within the dispensing duct 101 there is no contact. In the embodiment of figure 10 the dispensing pipe 104 can comprise a support 105 for the thermostatic valve 1 , preferably, but not limited thereto, the thermostatic valve 1 according to the first or the second embodiment described herein.

[0295] The support 105 is preferably totally introduced within the dispensing pipe 104. This configuration should not be intended in a limiting way, since there could be a configuration wherein the support 105 is at least partially extending outside of the dispensing pipe 104.

[0296] It appears clear that in at least one embodiment the thermostatic valve 1 object of the present disclosure is configured to be introduced within the body of a faucet, and in particular within a dispensing pipe 104 of a faucet. Preferably, in such a case the outer body 2, 6 of the thermostatic valve 1 , which is therefore also configured to be introduced within the body of the faucet, preferably assumes a shape suitable for coupling to the shape of the support 105 or, alternatively or in combination, an at least partially circular shape in transversal section or overall, at least partially cylindrical.

[0297] The above should not be intended in a limiting way. The Applicant has likewise conceived an embodiment of the thermostatic valve 1 that, although configured and destined to be coupled to a faucet, and in particular to the dispensing pipe 104, lies substantially outside of the latter and / or constitutes a substantially ending portion thereof.

[0298] The support 105 retains the thermostatic valve 1 in a predefined position into said dispensing pipe 104 in correspondence of the lateral body 2. Alternatively, the support 105 can retain the thermostatic valve 1 in said predefined position into said dispensing pipe 104 in correspondence of the inlet body 6. Still alternatively, the support 105 can retain the thermostatic valve 1 in said predefined position into said dispensing pipe 104 in correspondence of both said inlet body 6 and in correspondence of said lateral body 2.

[0299] In a non-limiting embodiment, the dispensing pipe 104 is rigid, and is realized in stainless steel, for example, polished.

[0300] In a non-limiting way, the support 105 can be realized in plastic or metallic material, for example, aluminum or its alloy, brass or stainless steel. The support 105 can be joined to the dispensing pipe 104 by means of a threaded connection.

[0301] The support 105 identifies an auxiliary channel that allows the passage of water, in particular unconditioned water, from an upstream portion of the thermostatic valve 1 to a downstream portion of the thermostatic valve 1. In a non-limiting embodiment, such an auxiliary channel an annular channel and / or extends along a direction substantially parallel to the direction identified by the X axis.

[0302] In the non-limiting configuration of figure 10, the aerator 106 is positioned downstream of the support 105 and is open on the auxiliary duct. Also, the outlet 4i of the thermostatic valve 1 directly introduces fluid in use into said aerator 106.

[0303] The aerator 106 is preferably introduced, for example in a rigid way, into the dispensing pipe 104. Where the thermostatic valve 1 is movably connected with respect to the dispensing pipe 104, the aerator 106, particularly if placed downstream of the thermostatic valve 1 , will also be movably connected to the dispensing pipe.

[0304] The aerator comprises at least one channel for the fluid, in particular water, that flows within the dispensing pipe 104 but outside of the duct 101.

[0305] The duct 101 for conditioned water is connected to the inlet 3 of the thermostatic valve 1 and is arranged into said dispensing pipe 104. The duct 101 is connected with a first inlet 102 in use supplied with water added with carbon dioxide.

[0306] In a further embodiment, the thermostatic valve 1 although operatively connected to the dispensing pipe 104 can be placed outside with respect to the latter and also be movably connected to the latter, for example with a rotating joint and / or with a flexible connection.

[0307] The duct 101 is connected with a second inlet 103 supplied with hot water, preferably supplied with water having a temperature (T) substantially comprised in the range [70-100] °C, preferably [80-100] °C, or preferably [85-100] °C, or [90-100] °C.

[0308] It is observed that the connection of the duct 101 to the first inlet 102 and the second inlet 103 is not alternative. Although the first and the second inlet 102, 103 typically supply fluid into the duct 101 in an alternative manner, both are simultaneously connected to the duct 101 , in particular simultaneously mechanically connected to the duct 101 for example via a “Y”-shaped or “T”- shaped connection.

[0309] Preferably but not limiting thereto, the faucet 100 is destined to supply the duct 101 alternately with water added with carbon dioxide from the first inlet 102 or with hot water from the second inlet 103.

[0310] Although this should not be intended in a limiting way, the faucet described here is a domestic faucet.

[0311] In view of the above, the thermostatic valve 1 object of the present disclosure is configured to be installed downstream of the traditional adjusting valve of the faucet. The adjusting valve is preferably configured to allow, for example through a rototranslation action of a actuation control that in use is user-operated, the following functions:

[0312] - adjustment of water temperature; and

[0313] - adjustment of the flow (flow rate) of water.

[0314] In an embodiment that is not limiting, the above-mentioned control valve is placed upstream of the thermostatic valve 1 , of the jet breaker or aerator 106 and of the dispensing pipe 104.

[0315] A data processing unit is provided to control opening and / or adjusting actuators of the flow coming from the first inlet 102 and / or from the second inlet 103, and / or to adjust the flow of fluid that is introduced into the dispensing pipe 104 outside of the duct 101. The data processing unit, or control unit, can be a general purpose type processor specifically configured to perform one or more parts of the process identified in the present disclosure through the software or firmware program, or be an ASIC or dedicated processor or an FPGA, specifically programmed to perform at least part of the operations of the process described here, in particular to control the water dispensing process as above described.

[0316] The data processing unit can be integrated into the faucet 100 or be operationally associated therewith while lying outside of the faucet 100.

[0317] The elastic element that possesses a variable deformation force F according to a temperature taken by the fluid is described below in a non-limiting embodiment thereof. In particular, when in the form of a spring, in particular of a coil spring, the spring element is an elastic element with hysteresis (thermal hysteresis, deformation hysteresis, and in particular lengthening / compression hysteresis); this means that the deformation characteristic of said spring element varies according to whether it goes from a lower temperature to a higher temperature or vice versa. In particular, the length of the spring varies according to whether it passes from a lower temperature to a higher temperature or vice versa. In other words, the value taken by the length of the spring is a function not only of the instantaneous temperature values of the fluid but also of the temperature values that the fluid had taken in the past. The hysteresis in temperature can also be present for embodiments of elastic element other than a spring.

[0318] In an embodiment, the spring is configured to axially lengthen when the temperature of the fluid increases. Consequently, in an embodiment, the spring is configured to axially shorten when the temperature of the fluid decreases. Depending on the specific mounting configuration, it can be possible to have springs with reverse behavior characteristic.

[0319] The diagram in figure 11 shows in abscissa (horizontal axis) temperature values and in ordinate (vertical axis) the lengthening of the spring.

[0320] For increasing temperatures T, and starting from an initial temperature T1 preferably less than 20°C and in any case less than an initial temperature range between 10°C and 30°C, or between 15°C and 25°C, the length of the spring assumes a minimum value L1 . In that case, the length of the spring begins to increase for temperature values substantially close to 43°C, or anyway comprised between 38°C and 46°C. The length of the spring stabilizes at a maximum value L2 in correspondence of a temperature substantially close to 51 °C, or anyway comprised between 46°C and 54°C.

[0321] In the embodiment shown in figure 11 , L2-L1 = 2mm; preferably, but not limiting thereto L2-L1 e [0.5-5] mm.

[0322] For decreasing temperatures T, and starting from an initial temperature T2 preferably higher than 50°C and in any case higher than a second temperature range between 40°C and 60°C, or between 45°C and 55°C, the length of the spring assumes a maximum value L2. In that case, the length of the spring begins to decrease for temperature values substantially close to 25°C, or otherwise comprised between 21 °C and 29°C. The length of the spring stabilizes at the minimum value L1 in correspondence of a temperature substantially close to 18°C, or otherwise comprised between 21 °C and 13°C. In an embodiment the force impressed by the spring is substantially contained in the maximum range of 15N, and preferably is equal to 6N or 9N according to the lengthening configurations.

[0323] Therefore, it is observed that in the above-mentioned hysteresis, in an embodiment in decreasing temperature step, to obtain a deformation of the elastic element, it is necessary to reach a temperature lower with respect to the temperature necessary to obtain a deformation, in particular an equal and opposite deformation, of the elastic element in increasing temperature step.

[0324] The invention is not limited to the embodiments shown in the attached figures; therefore, the reference numbers that are present in the claims are provided for the sole purpose of increasing intelligibility and should not be considered limiting.

[0325] It is finally clear that changes, additions or variants obvious to an expert in the art can be applied to the object of the present disclosure, without departing from the scope provided by the attached claims.
