The hydraulic module 1 is implemented as an autonomous unit configured to be mounted in a predefined location on the steam iron.

Figure 2 shows a section of the steam iron, with the hydraulic module 1 of Figure 1 being mounted in a predefined location within the steam iron. In particular, Figure 2 shows the ironing sole 4 of the steam iron and a steam chamber 5 located directly above the ironing sole 4. The steam chamber 5 comprises one or more heating units and is adapted to evaporate water and to generate steam, where the steam generated in the steam chamber 5 is expelled from multiple steam outlet ports of the ironing sole 4. A mounting plate 6 is arranged at a distance above the ironing sole 4, the hydraulic module 1 being arranged in a predefined position of the mounting plate 6. The mounting plate 6 forms the floor of the steam iron water tank. When water is supplied to the water inlet 2 of the hydraulic module 1, the space above the mounting plate 6 is filled with water.

As soon as the temperature of the steam chamber 5 reaches the target temperature, the drip shut-off valve 10 opens. Now I know supply to the steam chamber 5 a flow of water from the water tank through the drip shut-off valve 10, the water supply conduit 11, and the water dosing unit 8. In the steam chamber 5, the water evaporates. Therefore, steam is generated in the steam chamber 5, this steam being expelled through the steam outlet ports of the ironing sole 4.

In figure 4, the lower side of the hydraulic module 1 is shown, the hydraulic module 1 being moved to its vertical position. In figure 4, both the drip shut-off valve 10 and the water dosing unit 8 are shown with the needle 9. The drip shut-off valve 10 comprises a bolt 12 with a sealing part 13. A bimetallic element 14 with a lever 15 configured to actuate the drip shut-off valve 10 is arranged on the upper side of the steam chamber 5. When the steam chamber 5 is heated to the target temperature, the bimetallic element 14 changes its shape and the lever 15 presses the bolt 12 of the drip shut-off valve 10 upwards. As a result, the bolt 12 with the sealing part 13 is moved upwards, thus leaving a path for the flow of the water tank to the water dosing unit 8 through the water supply conduit 11 free. As soon as the valve of the drip closure 10 is open, a flow of water is supplied to the steam chamber 5 from the water tank through the water supply conduit 11 and the water dosing unit 8. In the steam chamber 5, the Water evaporates and steam is expelled through the steam outlet ports of the ironing sole 4.

In the hydraulic module 1, the position of the needle 9 is adjusted depending on the temperature setting of the steam iron, which can be selected, for example, with a program selector switch or a temperature selector switch. If the temperature of the ironing sole 4 is set to a high value, the water flow will increase to generate a sufficient amount of steam. In contrast, if the temperature is set to a low value, the water flow will decrease. In the embodiment shown in Figures 1 to 5, the hydraulic module 1 comprises an oscillating mechanism configured to adjust the water flow rate supplied by the water dosing unit 8 depending on the temperature setting. The hydraulic module 1 comprises a jogger 16 hinged to the hydraulic module 1, where the jogger 16 can be pivoted about a rotation axis 17.

The program selector switch or the plate temperature selector switch may be shaped such that a first lever arm of the jogger 16 is pushed down if the selector switch is set to a High temperature. A roller 18 may have been mounted on the first lever arm of the jogger 16, the roller 18 being pressed against an adjacent surface of the respective selector switch. If the first lever arm of the jogger 16 is moved downwards, as indicated by arrow 19 in Figure 1, the second lever arm of the jogger 16 is moved upwards, as indicated by arrow 20. The needle 9 of the water dosing unit 8 is coupled with the second lever arm of the jogger 16 and will also be moved upward, thus increasing the flow of water supplied to the steam chamber 5.

The hydraulic module 1 also comprises a steam booster unit 21 arranged on the base plate 3. By pressing a button of the steam booster unit 21, an additional volume of water can be injected into the steam chamber 5. The additional volume of water it will evaporate, so steam boost is generated. As shown in Figures 1 and 3 and, in particular, in the exploded view of Figure 5, the steam booster unit 21 comprises a tubular liner 22, with a steam booster button 23 which is disposed in a movable manner. in the tubular lining 22. The steam booster unit 21 also comprises a spring 24 configured to push the steam booster button 23 upwards, and a washer 25. When the steam booster button 23 is operated, in the steam chamber 5 an additional volume of water is injected, so that additional steam boost is generated.

In addition, the hydraulic module 1 is equipped with a water spray unit 26. By pressing a button of the water spray unit 26, a water spray can be generated, where water spraying can be used, for example, to wet A piece of clothing. As shown in Figure 5, the water spray unit 26 comprises a tubular liner 27, a water spray button 28, a spring 29, and a washer 30. When the water spray button 28 is operated , a certain amount of water is supplied to at least one nozzle, thus generating a water spray. The nozzle may be arranged, for example, on the ironing sole 4 or on the front end of the iron housing.

As shown in Figures 1 and 4, a fence 31 is arranged next to the lower side of the hydraulic module 1. The fence 31 may, for example, be fixed to the lower side of the hydraulic module 1 or it may be formed in one piece with the base plate 3 of the hydraulic module 1. Preferably, the fence 31 is made as a "U" shaped wall element.

Figure 2 shows the hydraulic module 1 mounted in a predefined position inside the steam iron. It can be seen that the "U" shaped fence 31 extends from the lower side of the hydraulic module 1 to the floor of the water tank, that is, the upper surface of the mounting plate 6, and fits with a shaped counterpart of "U" 32. The counter-shaped "U" 32 is arranged on the upper surface of the mounting plate 6. Thus, a tray is formed, said tray being surrounded by the fence 31, the lower side of the hydraulic module 1, the "U" shaped counterpart 32, and the upper surface of the mounting plate 6. The fence 31 is closed towards the rear end of the plate and is open towards the front end thereof.

When the iron together with the hydraulic module 1 mounted inside it is brought to its vertical position, the hydraulic module 1 is also brought to the vertical position, said vertical position of the hydraulic module 1 being shown in Figure 4. It can be seen that, In the vertical position of the hydraulic module 1, the fence 31 is configured to retain a volume of water. In the event that the iron with the hydraulic module 1 is moved to its vertical position, the volume of water retained by the fence 31 serves as a water reservoir for the steam booster unit 21 and the water spray unit 26. When the steam booster button 23 of the steam booster unit 21 is operated, the steam booster unit 21 draws water from the volume of water retained by the fence 31, the additional volume of water supplied to the steam chamber 5 being generated to generate a steam boost. Similarly, when the water spray button 28 of the water spray unit 26 is operated, the water spray unit 26 draws water from the volume of water retained by the fence 31, the additional volume of water supplied to at least one nozzle to generate a water spray. Therefore, in the vertical position of the iron, the volume of water retained by the fence 31 serves as a water reservoir for the steam booster unit 21 and the water spray unit 26.

When the iron together with the hydraulic module 1 mounted therein is brought to its vertical position, the additional volume of water retained by the fence 31 makes it possible for the steam booster unit 21 to generate a quantity of steam boosts in the vertical position. of the iron. This makes it possible to treat a garment with steam enhancements while the iron is kept in its vertical position. The additional volume of water retained by the fence 31 also allows the water spray unit 26 to generate several water sprays in the vertical position of the plate. Thus, it is possible to try a garment with one or more steam enhancements or water sprays in the vertical position of the iron, for example, to eliminate wrinkles.

The hydraulic module 1 also provides a self-cleaning function to clean the interior of the steam chamber 5. During the operation of the steam iron, layers of lime and calcareous deposits are formed on the interior walls of the steam chamber 5. When the self-cleaning function is activated, a sudden discharge of cold water is supplied to the hot steam chamber 5. Due to the thermal shock caused by the discharge of water, the lime layers detach, and the limestone pieces can be removed through the steam outlet ports. To implement the cleaning function, the hydraulic module 1 comprises a self-cleaning unit with a cleaning button 33 that is movably mounted on the hydraulic module 1. To start the self-cleaning function, the cleaning button 33 can be pushed in in the direction indicated by arrow 34. The movement of the cleaning button 33 is indicated in Figures 3 and 5. As shown in Figure 5, the cleaning button 33 is shaped such that both the bolt 12 of the drip shut-off valve 10 as the needle 9 of the water dosing unit 8 is raised upwards when the cleaning button 33 is pressed inwards as indicated by arrow 34. As a result of the upward movement of the bolt 12 and the needle 9, the paths for the flow of the drip shut-off valve 10 and the water dosing unit 8 are opened and a sudden discharge of cold water from the ag tank is supplied ua to steam chamber 5 hot. The sudden discharge of water causes a thermal shock and the layers of lime inside the steam chamber 5 detach. After the self-cleaning operation has been performed, the cleaning button 33 can return to its initial position. In this sense, the cleaning button 33 can be realized as a spring loaded button.

In the embodiment shown in Figures 1 to 5, the self-cleaning function for supplying the cold water discharge is carried out in such a way that the cold water discharge is supplied through the water dosing unit 8 itself. Alternatively, the cleaning function can be carried out by providing an additional fluid channel in the hydraulic module 1, said additional fluid channel being configured to deliver a cold water discharge to the steam chamber 5. An embodiment of this type is shown schematically in Figure 6, where the identical or similar elements are functionally indicated with the same reference symbols as in Figures 1 to 5. Figure 6 shows a cross section of the hydraulic module 1, the water tank 35, and the steam chamber 5. During normal operation, the needle 9 is moved upwards with respect to the needle seat 36, and a flow of water is supplied to the steam chamber 5 through the duct water supply 11 and the water seat 36. The hydraulic module 1 further comprises an additional fluid channel 37 which extends through the base plate 3 of the hydraulic module 1 and the mounting plate 6. As shown in Figure 6, the additional fluid channel 37 is configured to provide an additional path for the flow of the water tank 35 to the steam chamber 5, which is provided in addition to the path for flow through the water dosing unit 8. During normal operation of the water dosing unit 8, the additional fluid channel 37 is closed by a closing element 38 which is pressed against the entrance of the additional fluid channel 37. To activate the cleaning function, the rod valve 39 of the water dosing unit 8 is moved to its upward position, as indicated by arrow 40. A protrusion of the closing element 38 is grasped by an emptying of the valve stem 39, and the closing element 38 it is moved upwards against the elastic force exerted by the spring element 41. Then, through the additional fluid channel 37, a sudden discharge of cold water is supplied to the steam chamber 5. Thus, the calcareous deposits are removed and the lime existing in the steam chamber 5. After the cleaning operation, the valve stem 39 is returned to its normal position, and the additional fluid channel 37 is closed by the closure element 38.

In Figures 7 and 8, another embodiment of a hydraulic module 42 for a steam iron is shown, where identical or similar elements are functionally indicated with the same reference symbols as in Figures 1 to 6.

In contrast to the embodiment shown in Figures 1 to 5, the hydraulic module 42 not only penetrates the water tank, but extends through the floor of the water tank. The hydraulic module 42 comprises a bottom plate 43 that is fixed to the base plate 3 through a "U" shaped fence 31. The plate lower 43 is configured to be introduced in a corresponding emptying of the tank floor. When the hydraulic module 42 is inserted into the steam iron, the bottom plate 43 is inserted into the emptying of the tank floor, while the base plate 3 is inserted into an opening of the upper cover of the water tank. The bottom seal 44 of the bottom plate 43 is configured to provide a circumferential seal relative to the tank floor.

The hydraulic module 42 comprises a water inlet 2 arranged on the base plate 3. The water tank can be filled with water through the water inlet 2. The hydraulic module 42 further comprises a water dosing unit 8 configured to supply a water flow with a given flow to the steam chamber. In the steam chamber, water evaporates and steam is generated at a predefined speed. To control the flow of water and, therefore, the flow of steam, the hydraulic module 42 comprises a steam flow regulator 45 configured to control the flow of water supplied to the steam chamber, where the flow depends on the position of the steam flow regulator 45. By way of example, the position of the steam flow regulator 45 can control the respective position of a dosing needle with respect to the needle seat 36. For example, a rotational movement of the flow regulator of steam 45 can be converted through a transmission into a rotary motion of a dosing needle. The dosing needle can comprise multiple openings at its tip, where the degree of overlap between the needle openings and the corresponding openings of the support determines the flow of water supplied to the steam chamber. Instead of turning the dosing needle, the flow rate can also be adjusted by moving a needle up or down with respect to the needle seat 36.

Also, the hydraulic module 42 comprises a drip shut-off valve 10. A water supply conduit 11 is configured to connect the drip shut-off valve 10 and the water dosing unit 8. as opposed to the fluids. Embodiments of Figures 1 to 5, the drip shut-off valve 10 and the water supply conduit 11 are mounted below the bottom plate 43 and form an integral part of the hydraulic module 42.

The drip shut-off valve 10 is configured to be operated by a bimetallic actuator, as shown in Figure 2, said bimetallic actuator being arranged in thermal contact with the steam chamber. As soon as the temperature of the steam chamber reaches a predetermined minimum value, the drip shut-off valve 10 opens and water is supplied from the water tank to the water dosing unit 8 through the water supply conduit 11. The water flow is supplied to the steam chamber in accordance with the respective position of the steam flow regulator 45.

The hydraulic module 42 also comprises a steam booster unit 21 and a water spray unit 26. The steam booster unit 21 is configured to supply an additional volume of water to the steam chamber to generate an additional amount of steam and comprises a tubular liner 22 and a steam enhancer button 23. When the steam enhancer button 23 is pressed down, an additional volume of water from the water tank is supplied to the steam chamber through a tube 46 and a water channel. steam discharge 47. In addition, the hydraulic module 42 comprises a water spray unit 26 configured to generate a water spray to moisten clothing. When the water spray button 28 is pressed down, water from the water tank is supplied through a tube 48 to a spray nozzle 49 disposed at the front end of the hydraulic module 42, where this spray nozzle 49 is part of the hydraulic module 42.

A "U" shaped fence 31 extends from the base plate 3 to the bottom plate 43, where the base plate 3, the "U" shaped fence 31, and the bottom plate 43 form a bucket. In the event that the steam iron is brought to its vertical position, a volume of water is retained by the bucket, where the volume of water retained serves as a water reservoir for the steam booster unit 21 and the spray unit of water 26. Therefore, it is possible to generate various steam enhancements and water sprays in the vertical position of the iron based on the volume of water retained in the bucket.

The hydraulic module 42 shown in Figures 7 and 8 comprises a self-cleaning function to remove the calcareous deposits and lime existing in the steam chamber 5. According to a first option, the self-cleaning function can be implemented by providing a discharge of cold water to the steam chamber 5 through the water dosing unit 8 itself. For this purpose, the steam flow regulator 45 can, for example, be moved to a position where a cold water discharge is supplied to the steam chamber 5 through the water dosing unit 8.

According to a second option, the cleaning function can be implemented by providing an additional fluid channel 37 such as that shown in Figure 6, said additional fluid channel 37 extending through the base plate 3 and the plate lower 43. When the closure element 38 is removed, a sudden cold water discharge from the water tank 35 can be delivered to the steam chamber 5 through the additional fluid channel 37.
