Definitions
- the present invention relates to a fluid delivery device for an iron
- Fluid requirements are used in irons to spray water from a water reservoir inside the iron via a nozzle in front of the iron onto the laundry to be ironed or to supply it to an evaporator, so that a burst of steam, for example, emerges from the underside of the iron are usually operated via an essentially cylindrical actuating button which protrudes from the housing of the iron and can be pressed down with the thumb.
- a iron is known, the fluid delivery device of which has a compressible rubber bellows as a pumping chamber, which is pressed together with a cup-shaped printhead
- Such fluid requirements are, however, relatively bulky and have disadvantages in terms of assembly and operability
- the present invention is therefore based on the object of creating an improved fluid delivery device for irons which avoids the disadvantages of known fluid delivery devices.
- a compact and easy-to-use fluid delivery device with a simple structure is to be created
- the fluid delivery device essentially has a lower module part and an upper module part, between which a flat membrane film is sandwiched, in which one piece both elastically movable valves and an elastic one deformable membrane are provided as the pump element.
- pump elements, valves, channels, supply and discharge lines are formed correspondingly multiple times in all housing module parts and the membrane llen preferably a single membrane takes over both the valve and the pumping functions
- the sandwich construction clamps the elastic membrane between the hard plastic parts in such a way that the elastic membrane deforms and thus the housing of the fluid delivery device is sealed off from the outside.
- the elastic connecting sections of the membrane between the pump element and the valves ensure that there are no leakage flows even within the fluid delivery device.
- the housing and the pump element are designed as two separate parts, which have a rigid connection to one another.
- the pump element can be clamped between two parts of the housing.
- the two housing parts can be connected to one another by a snap connection.
- the pump element can be connected to the housing by an elastic positive connection.
- the membrane has one, preferably a plurality of fastening sections, which cooperate with complementarily designed fastening sections of the housing.
- the elastic membrane also acts as a seal through this connection with or in the housing at edge regions, so that no additional sealingly clamped O-ring is required. No further sealing means are therefore required for the fluid delivery device.
- a compact design is also achieved in that all liquid channels are already formed in the housing parts.
- the membrane is advantageously a three-dimensional film that is easy to produce by injection molding.
- a valve in particular a check valve, is preferably provided in each case in a feed line and a discharge line of the pump chamber.
- the valve is formed by the elastic membrane itself.
- the membrane of the pump element or of the actuating part here has corresponding valve sections which are adapted to a corresponding valve channel so that they close the valve channel.
- valves by the elastic membrane itself reduces the number of components of the fluid delivery device, which results in a cost reduction.
- the valves are made of elastically sealing material (possibly integrally with the membrane) in the form of flat movable sections which interact with rigid parts and are moved against or away from them in the pump chamber depending on the negative or positive pressure.
- valve film on a valve section for the outlet of fluid is particularly thin-walled and provided with an opening whose diameter is smaller than a pin of the lower module part protruding through the opening. It has been shown that this valve closes particularly tightly.
- Other valve sections are designed as elastic tabs which are moved by the fluid pressure during suction or suction and which open or close an opening in one of the module parts.
- the valve which is intended to prevent a backflow of the delivered fluid (or / and also the other), can also be designed as a ball valve, possibly with a spring action. This allows a simple geometry of the membrane and greater freedom in the arrangement of the valve. However, the previously described integral design of the valve through the membrane permits a more compact construction of the fluid delivery device.
- the suction of fluid into the pumping chamber is fundamentally brought about by an elastic reshaping of the membrane after an actuation in its starting position, by means of which the pumping chamber volume is increased.
- the membrane is preferably reset independently due to its elasticity.
- a spring device for prestressing the pump element into the position in which the pump chamber volume is maximum can be provided in a further development of the invention or alternatively as the only resetting device.
- a separate spring element such as a cylinder spring or a leaf spring, can in principle be provided as the spring device.
- the spring element can be integrally formed in one piece with a part of the housing.
- the housing thus has a spring section which acts upon the membrane when it is deformed from its rest position towards the latter.
- the spring characteristic of the corresponding housing Sea sections can be achieved in particular by appropriate shaping of this section.
- the membrane itself can have a spring section which supports the self-supporting section of the membrane to be deformed and is deformed when the membrane is actuated.
- the spring element can thus be formed as an integrally integral part of the membrane.
- the membrane is preferably designed in such a way that a resistance to deformation of the membrane in the rest position of the membrane has an initial high value and, after an initial deformation has been exceeded, drops to lower values which are lower than the initially high value .
- the membrane thus has an initially high resistance when it is pressed in, which then drops to a lower value when it is pressed in further after the initial high resistance has been overcome.
- the increased, defined pressure point of the membrane with the non-linear, in particular abruptly decreasing deformation resistance after overcoming the pressure point brings about a precise actuation and gives the operator the feeling of a controlled, yet not force-intensive actuation.
- This comfortable movement characteristic is in clear contrast to that of known bellows.
- the membrane can preferably be convex in relation to its side facing away from the pump chamber.
- the dome-shaped shape of the membrane causes the membrane to buckle in the edge area when actuated, as a result of which an initially high resistance to deformation decreases sharply.
- the membrane can have a greater thickness in a central area than in the edge areas.
- the membrane has greater rigidity in the central area and an enlarged displacement area when the membrane is pressed into the pumping chamber.
- the membrane can have an increased pressure area with respect to an edge area, which is preferably about the size of a finger tip.
- an actuating part for actuating the pump element is designed as a deformable membrane.
- An elastic membrane, which can be deformed with finger pressure, is therefore provided for actuation.
- the actuator can be free of bulky push buttons protruding from the iron housing. This has the advantage that the iron housing can be designed more freely and ergonomically adapted to the hand.
- the design of the actuating part as an elastic membrane brings about a pleasantly soft and soft operation of the fluid delivery device.
- the actuation is advantageously carried out by deforming the actuating part itself.
- the actuating part is preferably fixedly mounted relative to the housing, in particular with its edge connected to the housing all around. So there is no linear displacement of the entire actuating part.
- the actuating part can be actuated multidirectionally and is not tied to a predetermined direction of movement. Tilting of the operating part is impossible. Frictional resistances, such as occur when a linearly displaceable operating button is pressed between the latter and the housing, are avoided.
- the actuating part can form part of the housing, that is to say part of the housing is designed as a deformable membrane. In contrast, the remaining part of the housing can be rigid.
- the actuating part is designed directly as a pump element.
- the elastic membrane forms the pump element and delimits the pump chamber, so that the pump chamber volume can be changed by deformation of the membrane and the liquid can be pumped. An operator's finger pressure is immediately converted into a pump movement.
- the pump element is spaced from the actuating part, the pump element preferably being designed as an elastic membrane.
- Two elastic membranes are therefore provided which are spaced apart from one another, the membrane provided as the pump element being able to be designed in principle in accordance with the membrane provided as the actuating part.
- the two membranes can be formed from different materials that are adapted to the respective function.
- the pump element membrane can consist of a silicone, while a soft polyethylene such as TPE can be used for the actuating part, which creates an aesthetic outer surface.
- the two membranes can be so closely spaced from one another that a deformation of the actuating part is transmitted directly to the pump element, i.e. the membrane of the actuating part can be deformed in such a way that it touches the pump element directly or indirectly (see next paragraph) and also deforms it in the process .
- a transmission device in particular a mechanically rigid transmission element, can be provided between the actuation part and the pump element, which transmits a movement of the actuation part to the pump element.
- the pump element can be arranged independently of the position of the actuating part in the interior of the iron, in particular the pump element can be arranged directly on or in the fluid reservoir in the interior of the iron.
- the supply line from the fluid reservoir to the pump element and the pump chamber is shortened.
- the pump element and the housing are designed as a one-piece two-component injection molded part.
- the membrane and the housing are therefore integrally connected to one another.
- the integral design of the membrane with the housing results in a particularly simple construction with few components.
- the design of the actuating part as an elastic membrane has particular advantages with regard to the external design of the iron housing.
- the membrane of the actuating part is arranged essentially flush with the outer surface of the iron housing and continues the outer surface of the iron housing essentially continuously.
- the iron housing is also flat in the area of the operating part, e.g. free of protrusions and has a flowing surface.
- the iron housing can also be designed as a handle part in the area of the actuating part. Alternatively, ergonomically designed actuation projections can be formed.
- the membrane of the actuating part can be part of the iron housing, in particular the membrane can be formed integrally with the iron housing as a two-component molded casting.
- the housing of the fluid delivery device can be firmly connected to the iron housing, in particular to a handle section of the iron housing.
- the connection can preferably be achieved by two-component injection molding, plastic welding or gluing.
- a snap or press connection is provided as the connection.
- the housing of the fluid delivery device can optionally be at least partially formed by a correspondingly shaped section of the iron housing.

- the actuating part 15 is rigid, so that the pressure resistance is mainly formed by the membrane of the pump. This variant can be transferred to all embodiments in which the membrane or the pressure rod 27 can be covered by a rigid actuating part.
- FIG. 16 shows, a separate fluid delivery device is provided for the spray nozzle 9 and for the steam boost function, these being combined as one structural unit.
- the fluid delivery device is arranged directly on a bottom 28 of the fluid reservoir 6 (cf. also FIG. 17) in the latter.
- a return spring 29 for returning the pump element 14 to its starting position is preferably provided in the interior of the pump chamber 2.
- the resetting of the pump element 14 thus takes place on the one hand due to the elasticity of the membrane 4 and on the other hand due to the restoring force of the restoring spring 29.
- the increased restoring force achieved by the restoring spring 29 causes a more powerful suction of the fluid from the fluid reservoir 6 into the pumping chamber 2 and faster Reset that allows an increased actuation cycle.
- An advantageous embodiment of the return spring 29 is that it is designed as a conical coil spring in profile.
- the check valves 7 and 10 which allow fluid flow in the supply line 5 and the pressure line 8 in only one direction each, are formed directly by the elastic membrane 4.
- the membrane 4 of the pump element 14 in this case has a valve section 70 or 100, each of which is elastic between a first position in which the associated fluid line 5 or 8 is closed and a second position in which the respective fluid line is open, is mobile.
- the valve sections 70 and 100 are each designed as self-supporting valve plugs, which can bend away at a corresponding pressure of the fluid present.
- valve sections 70 and 100 In their position closing the fluid channel, the valve sections 70 and 100 each abut a valve section stop 30 and 30a, each of which bends the valve sections 70 and 100 away in one direction which should prevent fluid flow
- the stop faces of the valve section stops 30 and 30a preferably extend perpendicular to the flow direction through the corresponding fluid line, the fluid flow of which should control the valve sections
- FIG. 19 also shows check valves 7 and 10 which are formed directly by the membrane 4 itself.
- the corresponding valve sections 70 and 100 of the membrane 4 are also supported against valve section stops 30 and 31.
- the valve sections preferably have sealing surfaces 71 which have correspondingly complementary valve seat surfaces interact on the fluid channel 5 or 8 to be closed
- FIG. 19a shows a pump module similar to that of FIG. 19, the membrane 4 being clamped between a lower module part 200 and an upper module part 201.
- the membrane 4 is pressed together sufficiently at the contact points with the module parts so that a sealing sandwich structure is formed
- the pump module therefore consists of only three parts, which can be plugged onto one another in a very simple assembly process.
- a cylindrically shaped spring 29 is arranged in the pump chamber 2.
- the spring 29 provides a restoring force for the membrane 4, regardless of the permanently elastic properties the diaphragm 4
- the spring 29 is held stationary on the diaphragm 4 by a cylindrical extension with a smaller diameter - relative to the inside diameter of the spring 29.
- the upper pump module 201 also has a guide section 206 for guiding the pressure rod 27. Adjacent to the guide 206, a bead 207 is arranged in a concentric circle relative to the guide 206, onto which sealing rubbers for the pressure rod 27 can be placed opposite the membrane 4
- the inlet check valve draws water directly from the liquid reservoir
- the inlet valve 208 is designed as a circular elastic tab which is pressed against the stop surfaces of the upper pump module 201 as soon as the membrane 4 is pressed in.
- the outlet valve 209 is constructed differently and is shown again enlarged in FIG. 19c.
- the outlet check valve 209 is formed by a section of the membrane 4 which is thin enough compared to the adjacent sections so that it can deform accordingly.
- This thin elastic valve section of the outlet valve has a circular opening, the diameter of which is smaller than the diameter of the pin 210, over which the elastic valve section is placed.
- the thin-walled elastic valve section of the outlet valve is pushed up to the conically tapering section 211 of the pin 210, so that a gap is created through which water escapes from the pump module upwards .
- valve device 209 has the advantage over other valve devices that a particularly good sealing effect can be achieved, so that no dripping can be observed at the consumers.
- FIG. 19d shows a fluid delivery device in an interconnected manner, the lower module part 300 and the upper module part 301 in particular being identified. are cash.
- the membrane 304 in the assembled form of the pump is covered by the upper module part and is therefore shown separately with FIG. 19e.
- a first feed line 302 is shown in FIG. 19d.
- a second supply line extends vertically from below in the lower module part 300. Both supply lines draw the water from the fluid reservoir in which the ends of the supply lines extend. After the fluid delivery device is already attached to the fluid storage unit, the delivery path from the feed lines is short. From the supply lines, the water reaches an opening below the flap-like elastic valve sections 303 and 305. When moving upwards after at least one of the two dome-shaped pump elements 306, 307 is pressed in, the correspondingly assigned valve section 303, 305 is moved upward by the negative pressure present, so that water flows into the respective pumping chamber below the pumping element via the corresponding supply line.
- the water flows through one of the flow channels 308 or 309 integrated in the upper module part 301 through the openings 310 or 31 1 into the respective channel in the lower module part 300, which is in fluid communication with the pumping chamber.
- the valve sections 303 and 305 can pivot freely upward into the flow channels 308, 309, in Figure 19e the U-shaped recesses in the membrane are shown, which surround the valve sections 303, 305 and allow the pivoting movement.
- material thinnings 312, 313 are provided in the membrane around the pivot axis.
- the water contained in the pump chamber flows via flow channels in the lower module part 300 to the outlet valve sections 314 and 315.
- the outlet valves are designed here as shown in FIG. 19c. It is not possible for the water to flow back into the supply lines, since the valve sections 303, 305 are pressed against a bearing surface of the lower module part 300 which delimits the supply opening.
- the valve sections for the outlet the water flows through drains / channels 316, 317 which are formed by the upper module part and the membrane 304. The water then flows through openings 318 and 319 in the membrane in outlets 320 and 321 of the lower module part 300.
- Derivation 320 leads directly into the steam chamber arranged below for the generation of a burst of steam.
- the drain 321 leads to the water spray.
- one actuating part each is designed to be elastic or rigid, which has a respective pressure rod that is guided through the fluid reservoir. and whose other end rests on the respective pump elements, is indirectly connected to the pumps.
- this fluid delivery device is very simple.
- a spring is first inserted into the pump chamber.
- the membrane with the integrally formed pump elements 306 and 307 and valve sections 303, 305, 314, 315 is attached from above.
- the lower module part 300 has vertical fastening pins 322, which correspond to complementary fastening openings or cutouts in the membrane 304 and fastening openings 324 in the upper module part 301, which can also be plugged on.
- the upper module part 301 is then pressed onto the lower module part and against the elasticity of the membrane 304 lying therebetween, the fastening pins 322 being deformed like hot rivets at the same time, so that the membrane 304 is clamped or clamped in a fluid-tight manner on all sides. Inserting the spring is optional because the pump elements 306, 307 already have a resetting spring characteristic.
- spring elements can be provided as the restoring spring 29, which are integrally formed, for example, on the elastic membrane 4.
- the spring elements of the return spring 29 are preferably connected to the central area of the membrane 4 in order to bias it back into its initial position when the membrane is deformed.
- the spring elements are preferably designed as curved webs which protrude into the pumping chamber 2, so that they abut and deform when the membrane 4 is pressed in at the bottom of the pumping chamber 2.
- the spring elements are preferably stressed on bending.
- the molded-on spring elements can also have an essentially straight profile, so that they have an increased initial resistance to deformation, which drops relatively sharply after the spring elements buckle.
- the return spring 29 is integrally formed in one piece with a section of the housing 1 of the pump chamber 2.
- the return spring 29 is arranged directly below the membrane 4 in the pump chamber 2, so that the membrane 4 rests on the return spring 29 in its rest position.
- the return spring 29 has a plurality of spring arms 33a which are connected to one another in the central region of the pumping chamber 2 and with their other edges each to edge sections of the housing 1 arranged around the membrane 4.
- the spring arms 33a are curved, preferably meandering, in particular curved in an S shape, in order to bring about the elasticity of the spring arms 33a.
- an essentially plate-shaped membrane support element 33 is provided for connecting the spring arms 33a in the central region of the pump chamber 2, which supports the membrane 4 flat in its central region or prestresses it towards its initial position when deformed.
- the different embodiments of the return spring 29 can be combined with one another in order to bring about a desired spring characteristic or return characteristic.
- the membrane 4 has a substantially disk-shaped edge region 39, with which it can be attached to the housing 1 or can be formed integrally therewith. From the edge area, the thickness of the membrane 4 increases continuously towards the center of the membrane, so that the rigidity of the membrane increases towards the center.
- the top of the membrane that is to say the side facing the actuating finger, is convexly curved and forms an increased pressure area in the central area, which is pleasant and easy to press down.
- the underside that is to say the side of the membrane 4 facing the pump chamber 2, is essentially flat. When the membrane is pressed down, it is predominantly subjected to tension internally. Due to the uniform shape of the membrane, it is evenly stressed, which increases the service life.
- the membrane 4 can have a greatly increased thickness in its central region.
- the membrane can have an im in the middle have substantially cylindrical or cuboid-shaped stair-shaped raised pressure surface 34.
- the greatly increased pressure surface 34 causes the membrane 4 to be impressed particularly easily and the fluid delivery device to be operated in a correspondingly pleasant manner.
- the membrane 4 is essentially disc-shaped predominantly strained
- the membrane can be designed in the form of a dome as a whole, wherein preferably a straight, inclined flank region is arranged so that it slopes away from a central central region towards the edges of the membrane.
- the central central region has an increased thickness, while the flank section 35 is relatively thin in relation to this, so that it bends away in the form of a bellows when the membrane is at low pressure.
- the central middle region forms an essentially flat raised pressure surface 34.
- the membrane is predominantly subjected to bending. Due to the straight extending and inclined flank section 35, the membrane has in its initial position a relatively high strength against deformation, which decreases relatively strongly after an initial buckling or bending.
- the membrane has a defined pressure point.
- the dome-shaped design with the deformation-resistant central part causes a large volume change in the pumping chamber 2 when the membrane is deformed, and a correspondingly high pumping capacity
- FIG. 26 shows a design of the membrane similar to that of FIG. 25, the flank section 35 here being more inclined, that is to say enclosing a smaller angle with respect to the direction of insertion, that is to say it is steeper. This results in an even higher initial resistance and pressure point.
- a round undercut 36 similar to the embodiment according to FIG. 25, is provided between the flank section 35 and the thickened middle region of the membrane (cf. FIG. 26).
- FIG. 27 Another preferred embodiment of a membrane 4 is shown in FIG. 27.
- the membrane 4 is domed in its central region.
- the thickness of the membrane is substantially uniform between the base points of the dome-shaped curvature and decreases slightly from the center of the membrane to the base points of the dome-shaped curvature.
- the disk-shaped edge regions of the membrane are slightly reduced in thickness relative to the dome-shaped central region.
- the height of the dome-shaped curvature corresponds to approximately one fifth of the diameter of the dome-shaped arched area of the membrane.
- undercuts 36 are provided in the area of the base points of the dome-shaped curvature on the underside of the membrane, which are shown in an enlarged view in FIG.
- the dome-shaped arched membrane 4 according to FIG. 27 is subjected to both tensile and bending stresses when pressed.
- FIG. 29 shows a further embodiment of a membrane 4, which likewise shows a very favorable buckling behavior (cf. claim 9).
- part 37 of the membrane is arranged below the edge region 39 and part 38 of the membrane 4 above the edge region 39 of the membrane 4.
- the connection to the edge region 39 to the upper membrane part 38 of the membrane 4 is U-shaped in section, so that a predetermined notch is given.
- the parts can also be connected to one another by plastic welding, gluing or clipping by means of latching mechanisms.
- the fluid delivery device has been described above in connection with an iron.
- the fluid delivery device can also be used for other household appliances and used expediently.
- the fluid delivery device described is particularly advantageous for fluid delivery in irons.
- a particularly advantageous embodiment of the delivery device can also consist in the pump chamber being formed in the manner of a cushion from an elastic membrane which is arranged between pump chamber shells. By squeezing the pumping chamber shells, the membrane is also pressed together, whereby the volume of the membrane cushion is reduced and a corresponding pumping effect can be achieved.
