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.
