Definitions

  • the invention relates first of all to a water refill container for a liquid tank, in particular for a pressure vessel of a household steam ironing apparatus, with a container neck which is adapted in its outer diameter to an inner diameter of a filler neck of the pressure vessel.
  • a water refill container of the type in question, in particular for filling a pressure vessel of a household steam ironing device is known from DE 10301209 A1 known.
  • This container designed as a pressure vessel liquid tank is refillable or refillable.
  • the user is a Provided means to hand over the refill container first fresh liquid into the tank to rinse this first, which introduced fresh rinsing liquid, if necessary, mixed with a residual liquid on the combined refill container is sucked off again. It requires correspondingly no cumbersome handling of two separate containers or the handling of a container with two different essays to perform the necessary at regular intervals rinsing of the tank. However, such flushing of the tank is quite necessary depending on the application because of possible corrosion and clogging of the tank system.
  • the emptying and flushing in particular of a pressure vessel of a household steam ironing device is complex for the user according to the known solutions. Therefore, this necessary rinsing process is often neglected. Due to the residual liquid remaining in the pressure vessel, corrosion occurs in the interior of the pressure vessel over time until it eventually becomes damaged. Therefore, it is imperative that the pressure vessel rinsed regularly, that is, the residual water is emptied so that the pressure vessel does not corrode.
  • the inventive combination of the container for refilling and emptying the residual by emptying the pressure vessel, this flushing process can be performed regularly and possibly inevitably.
  • the suction of residual liquid can be used automatically before the actual filling process, which is supported by the separately provided chambers for storing the fresh liquid and the residual liquid and by the combination of suction and refilling.
  • the water refill container is independent of the location ready for use, since this receives the fresh liquid and the absorbed residual liquid itself. Accordingly, it does not require connection to a water pipe or to an additional residual liquid tank.
  • the fresh liquid sub-chamber is closed by a valve which is to be opened by an opening part when the container neck is introduced into the tank opening. Accordingly, the fresh liquid sub-chamber is activated in the course of placing the refill container on the tank, according to which immediately after a proper application of the container, the fresh liquid inlet into the tank begins.
  • the opening part for releasing the fresh liquid may be connected to a cooperating with the filler neck of the tank collar or the like of the container, said collar opens on the filler neck supporting the further movement of the container in the tank opening the valve.
  • the opening part is a push rod.
  • such a plunger can cooperate, for example, with the filler neck of the tank, further alternatively with further associated areas of the tank.
  • the pressure ram is provided in the region of the container neck and interacts with the portion of the tank bottom opposite the filler neck.
  • the plunger can act on the valve via deflection.
  • Preferred in this regard is an embodiment in which the pressure ram is firmly connected to the valve, so on, for example glued or welded to this. Accordingly, a preferred translation of plunger displacement to valve displacement in the ratio of 1: 1.
  • a suction line For sucking residual liquid from the tank or pressure vessel, a suction line is provided which opens into the residual liquid sub-chamber.
  • This suction line preferably extends in the insertion position into the area the tank bottom so as to be able to absorb in the course of the flushing process in the tank bottom area settling dirt particles.
  • the residual liquid sub-chamber and the fresh liquid sub-chamber communicate with the same, resulting in filling position of the container, closed airspace.
  • a rinsing process which automatically adjusts itself before the filling process can be realized, this being due to prevailing pressure conditions between the closed air space and the environment.
  • the container comes in particular for the flushing but also beyond for the filling without any additional power.
  • the container preferably dispenses with the energy balance completely from the energy potentials of the pressures of the various water columns of fresh liquid and residual liquid sub-chambers present in the system.
  • each filling inevitably precedes a rinsing and emptying of the tank.
  • the rinsing process is triggered independently. This sequence inevitably repeats each time the tank is filled.
  • a rinsing process takes place, in which a fresh water subset filled in the tank is immediately absorbed again via the suction line into the residual liquid sub-chamber, wherein the dry deposits located in the tank be carried away. It is thus achieved a pure flushing, in which clean fresh liquid is contaminated with residual sediment and then immediately sucked up again to fill the cleaned tank with fresh liquid afterwards.
  • the suction line is firmly connected to the valve.
  • the suction line at the same time forms the plunger for valve actuation.
  • the suction line is received in the container neck, which also has a fresh-fluid dispensing opening.
  • the residual liquid suction opening and the fresh liquid dispensing opening are in a preferred embodiment on the container axially, that is arranged offset vertically to each other in the filling position, wherein more preferably in the filling position, the dispensing opening is viewed in the axial direction is positioned above the suction opening, from which it follows that the suction opening in the suction direction is arranged in front of the dispensing opening.
  • the suction opening directed, for example, down in the direction of the tank bottom centrally, further provided for example coincident with the Be Zellnishalsachse, while further example, the dispensing opening of the dispensing line is formed by a radial opening of Be confrontnishalses.
  • the residual liquid suction line and the fresh liquid dispensing line are preferably formed in the container neck as concentric lines, but may alternatively be provided in juxtaposed arrangement in the container neck.
  • the dispensing line comprises the suction line like a sleeve.
  • the dispensing line can also be arranged radially on the inside and the suction line can be arranged at least partially encompassing the dispensing line radially on the outside.
  • the fresh liquid sub-chamber In dispensing position, the fresh liquid sub-chamber is formed above the residual liquid sub-chamber.
  • the residual liquid suction line preferably passes through the fresh liquid sub-chamber, thus, for example, to form a U-shaped line section, which, after passing through the fresh liquid sub-chamber in the filling position, opens from above into the residual liquid sub-chamber.
  • the automatic triggering of the flushing process as well as the automatic stop thereof and the filling of the tank with fresh water, which is carried out hereafter, are further achieved by connecting a venting line to the volume of air while passing through the fresh liquid partial chamber in the dispensing position.
  • This vent line is otherwise with the residual liquid sub-chamber connected and acts in the filling position of the container as a riser for the recorded in the residual liquid sub-chamber, sucked up residual liquid which is in the riser rising water column in dependence on the decreasing in the fresh liquid sub-chamber by expiry of the fresh liquid fresh water column in proportion.
  • a venting line to the volume of air while passing through the fresh liquid partial chamber in the dispensing position.
  • This vent line is otherwise with the residual liquid sub-chamber connected and acts in the filling position of the container as a riser for the recorded in the residual liquid sub-chamber, sucked up residual liquid which is in the riser rising water column in dependence on the decreasing in the fresh liquid sub-chamber by expiry of the fresh liquid fresh
  • the sub-chambers are separable from each other, including, for example, the two sub-chambers are screw-connected with each other.
  • Other sealing occlusive connections are possible in this regard, for example, using a screw-on or alsklippsbaren annular flange which is connected to the container neck, which comprises annular flange radial collars of the sub-chambers.
  • the residual liquid sub-chamber may have a separate emptying closure, which is provided, for example, with a screw cap or a stopper.
  • the invention further relates to a method for emptying a liquid tank, in particular a water tank of a domestic steam ironing apparatus, wherein the tank has a filling opening and residual liquid is sucked out of the tank.
  • the residual liquid is sucked into the same container, from which the fresh liquid is applied. Accordingly, it does not require the arrangement and handling of two separate containers for the suction and the introduction of fresh liquid, which further improves handling. Thus, it is provided in a development that the residual liquid is sucked in a different sub-chamber of the container than the sub-chamber in which the fresh liquid is.
  • the sub-chambers within the container for example, be arranged coaxially to each other, but alternatively, for example, in axial superimposition.
  • the suction of the residual liquid is preferably carried out using the weight of the fresh liquid, so on, using the prevailing pressures in the various water columns of the sub-chambers and their line sections. Accordingly, the process does not require any additional auxiliary energy.
  • the energy budget is completely disputed from the energy potentials in the piping / chamber system.
  • valve seal which initially closes the sub-chamber containing the fresh liquid and which is displaced into the open position in the course of insertion of the container into the filling opening of the tank.
  • This valve seal acts both on the suction opening for the residual liquid and on the dispensing opening for the fresh liquid, according to which both processes are triggered only by a valve actuation.
  • the container neck is introduced into the sump of the tank, which leads to an increased removal of accumulating on the bottom of the tank residues in the course of the suction process.
