Definitions

  • the invention relates to a pressure storage device, comprising a storage container with a first area and a second area, a connecting piece with a closable opening being formed on the second area, and a steam valve which is arranged on the storage container.
  • the invention also relates to a hand-held steam device which can be operated hand-held.
  • Devices for generating steam are, for example, from DE 103 01 450 A1 , the EP 0 509 617 A2 , the EP 0 772 000 A1 , the WO 2004/005605 A1 , the WO 2005/003627 A1 , the WO 2012/077832 A2 , the US 2005/0034489 , the U.S. 6,101,316 , the U.S. 6,397,502 , the JP 2011152256 A , the JP 04045302 A , the JP 04051487 A or the CN 201524670 U known.
  • the invention is based on the object of providing a pressure accumulator device of the type mentioned at the outset, which has a minimized number of components with small height dimensions.
  • the storage container has an indentation between the first area and the second area, which is delimited by a first wall of the first area and a second wall of the second area, that on the first area the steam valve is seated in the indentation and that the steam valve is aligned parallel to the connecting piece with the opening.
  • a free space is provided on the storage container which at least partially accommodates the steam valve.
  • the height dimensions of the pressure accumulator device as a whole can be kept small.
  • the steam valve does not protrude completely over the Storage container addition, but does not protrude or at most over part of its height above this.
  • the corresponding pressure storage device can advantageously be used in a hand-held steam device due to the corresponding minimized height dimensioning.
  • the storage container can hold a sufficient amount of fluid for steam formation or steam storage.
  • the steam valve is arranged directly on the storage container.
  • the pressure storage device can be handled as a whole, that is to say as a unit, during manufacture, and the manufacture of a corresponding steam device, and in particular a hand-held steam device, is simplified.
  • the first wall and the second wall are connected to one another.
  • the indentation for (at least partially) receiving the steam valve can be implemented in a simple manner.
  • the second wall is oriented transversely and in particular perpendicular to the first wall. This results in a minimized restriction with regard to the volume capacity of fluid by the storage container.
  • a step is formed between the first area and the second area at the indentation.
  • the steam valve can be positioned at the step while minimizing the height dimensions of the pressure storage device as a combination of steam valve and storage container.
  • the second area has a smaller transverse width than the first area.
  • a base for fixing the steam valve is provided on the first area.
  • the steam valve is positioned on the first wall in the indentation and in particular positioned at a distance from the second wall.
  • the steam valve is fixed in particular on the first wall.
  • the steam valve has an actuating device for opening and closing the steam valve, which is at least approximately parallel to the second wall. This results in a space-saving structure. Furthermore, the steam valve for opening and closing can be operated in a simple manner and the necessary components can be implemented in a space-saving manner.
  • the steam valve has an actuation direction for opening and closing the steam valve which is at least approximately parallel to an opening direction of the opening in the second area.
  • the opening in the second area is in particular an expectation opening or an opening through which liquid can be poured into the storage container.
  • An optimized use of space results when the opening direction is oriented at least approximately parallel to the actuation direction.
  • the pressure storage device can advantageously be accommodated in a hand-held steam device.
  • the first wall is oriented transversely to an opening direction of the opening on the second area. This results in a space-saving design for the combination of storage container and steam valve. In particular, the height dimensions can be kept small.
  • the second wall is oriented at least approximately parallel to an opening direction of the opening on the second area. Furthermore, a correspondingly large receiving volume for fluid can thereby be provided in the storage container.
  • the steam valve does not protrude beyond a roof of the second area or at most by 5 cm above the roof of the second area. As a result, the height dimensions in the pressure storage device as a combination of the storage container and the steam valve can be minimized.
  • the first region of the storage container advantageously has a receiving space for liquid and / or is connected to a receiving space for liquid and has a receiving space for steam. This allows the steam generation to be optimized and the steam output to be optimized.
  • the second area has a receiving space for steam in a steam mode.
  • the pressure storage device can be used in an optimized way in a hand-held steam device.
  • the first area has a discharge opening for steam which is arranged on the first wall and on which the steam valve is located. This results in a space-saving training.

  • the retaining grid is arranged in an interior of the storage container. The retention grid prevents particles from entering the dispensing opening and the steam valve.
  • the retaining grid is arranged on the first area. It can be fixed in a simple manner and its functionality can be optimized.
  • a tube element is arranged at the dispensing opening in an interior of the storage container, on which the retaining grille sits, the dispensing opening opening into the tube element at a first end of the tube element and an opposite, second end of the tube element opening into the second area.
  • a lower space is provided which can be separated off via the retaining grille.
  • the retention grille prevents particles from entering the lower space. This in turn prevents particles from penetrating into the dispensing opening.
  • a continuation of a wall of the tubular element at least partially forms the second wall. This results in a simple structural design.
  • a surge element is assigned to the dispensing opening, a vapor space being formed between the dispensing opening and the surge element.
  • the surge element is used to calm a liquid surface when the pressure storage device (for example a hand-held steam device) is moved and thereby to prevent liquid from being carried along by a stream of steam.
  • the surge element is arranged in the second area. In this way, the entrainment of liquid and penetration into the dispensing opening can be largely prevented.
  • the surge element is at least partially applied to an inside of the storage container and has at least one gap for steam to pass through. This allows steam to pass into a space behind the surge element and over the Discharge opening are discharged.
  • the at least one gap can be realized in a simple manner by placing it on the inside. If there is no provision for a sealed application, the at least one gap is created automatically, so to speak.
  • the at least one gap is formed between the surge element and the inside. This results in a simple producibility with a simple structural design. In principle, it is also possible for a gap to be produced in the surge element itself. If the at least one gap is formed between the surge element and the inside, then the surge element as such can be realized in a fluid-tight manner and the passage of steam is achieved through the space between the surge element and the inside.
  • the at least one gap has a width in the range between 0.2 mm and 1.0 mm.
  • the width is preferably between 0.4 mm and 0.6 mm.
  • the surge element has at least one (flow) separation edge.
  • the surge element has a first area and a second area, the second area being angled to the first area.
  • a tear-off edge can be easily implemented via the bend.
  • the second area of the swell element is arranged towards the second area of the storage device. This results in an effective training.
  • a distance between a retaining grille and the surge element is advantageously at least 1 mm. In this way, in particular, an accumulation of particles in the intermediate area between the retaining grille and the surge element is prevented.
  • the retaining grille in relation to a steam flow direction, is closer to the discharge opening than the surge element and in particular the retaining grille is located in a steam space defined by the surge element when steam is released.
  • the retaining grid does not interfere with the liquid surface calming function of the surge element.
  • a wall is arranged on the second region of the storage container, which wall separates a vapor space which is defined by the surge element.
  • the wall can in particular protrude into the first area. In this way, the surge element can be effectively positioned and its effect can be optimized.
  • a pin element is arranged in the interior, on which the surge element is fixed, wherein in particular the pin element is connected to the first wall. This allows the surge element to be fixed in a simple manner.

  • the storage container comprises a first region 132, a second region 134, which is arranged on the first region, and a third region 136, on which the first region 132 is arranged.
  • the storage container 130 is fixed via the third area 136 on or in the vicinity of the underside 52 in the interior space 24 of the housing 12 via the contact element or elements 78.
  • the third area 136 can be removed from the first area 132, the first area 132 and the third area 136 being connected to one another in a fluid-tight manner, for example by means of screws or bolts.
  • a heating device 138 and in particular an electrical heating device, is arranged on the third region 136. This allows steam (in particular water vapor) to be generated from liquid (in particular water) in the storage container 130 and stored there in a retrievable manner.
  • An electrical connection device 140 is arranged on the housing 12, via which the heating device 138 can be connected to a power supply system in order to provide the heating device 138 with the necessary electrical energy.

  • the first area 132 and the third area 136 are connected to one another via the flange 142a and the mating flange 142b.
  • the connecting piece 68 with the opening 80 is formed on the second region 134.
  • the cover which is a closure element for the pressure accumulator device 70 and thus for the maintenance opening 80, is also seated on the second region 134 of the storage container 130.

  • the steam valve is aligned at least approximately parallel to the connecting piece 68.
  • the opening 80 of the pressure accumulator device 70 in the second region 134 has an opening direction 152.
  • This opening direction 152 is transverse and in particular perpendicular to the underside 52.
  • the steam valve 100 is arranged parallel to the opening direction 152 in the indentation 144.

  • the indentation 144 is designed in relation to a corresponding height of the steam valve 100 in such a way that the steam valve 100 does not or only slightly protrudes beyond the roof 154 in the opening direction 152. In particular, the steam valve 100 protrudes beyond the roof 154 by an amount of at most 5 cm.
  • the height dimensions of the pressure accumulator device 70 (in a height direction parallel to the direction / opposite direction 104 or the opening direction 152) can be kept small.
  • the corresponding height dimensions of the housing 12 can in turn be kept small. This makes it possible to realize a hand-held steam device 10 which can be hand-held.
  • the steam valve 100 has a discharge connection 156 for steam (cf. for example Figure 9 ).
  • This discharge connection 156 is arranged laterally on the valve housing 106 and is positioned transversely and, for example, perpendicular to the direction / opposite direction 104 or the opening direction 152. In particular, it is arranged in the indentation 144.

  • a tubular element 164 is arranged in the interior 162. Part of a wall of the tubular element 164 is formed by a corresponding wall 166 of the first region 132 of the storage container 130. A portion 168 of the tubular element 164 is connected to the first wall 146. A continuation of this part 168 in the second region 134 is the second wall 148 in one embodiment.
  • a sub-space 170 is formed by the pipe element 164 in the interior 162 in front of the dispensing opening 160. This subspace 170 is delimited by a retaining grille 172. The retaining grille is fixed to the tubular member 164.
  • a pin element 174 is arranged in the interior 162. This pin element is in particular fixed on the wall 166 or formed on it. The pin member 174 holds the retainer grid.
  • the retention grid 172 serves to retain particles that may be dispensed through the dispensing opening 160.
  • the dispensing opening 160 has a smaller cross-sectional area than the subspace 170.
  • the retaining grille 172 in particular prevents clogging or damage to the dispensing opening 160 or the steam valve 100.
  • a wall 176 is arranged in the interior 162, which extends at least approximately parallel to the opening direction 152 and, starting from the second region 134, projects into the first region 132, that is to say beyond the first wall 146.
  • This wall 176 delimits the subspace 178 in the first area 132 and the second area 134.
  • This sub-space 178 is a steam space in a steam mode of the hand-held steam device 10. No liquid or as little liquid as possible should get into this subspace 178.
  • the wall 176 has a greater height than the second wall 148 in continuation of the wall 168.
  • a surge element 180 is fixed to the pin element 174.
  • the surge element 180 which is in particular a sheet metal part, delimits the subspace 178, which comprises the subspace 170, from the rest of the interior 162.
  • the surge element 180 is designed to be closed except for one or more gaps 182 which allow steam to pass through.
  • the surge element 180 is intended to prevent water from penetrating into the subspace 178 as far as possible.
  • the surge element 180 is also supported on the retaining grille 172 via a support 184.
  • the surge element 180 is loosely applied to an inner side 186 of the wall 176 (towards the lower space 178) and / or the wall 166.
  • the column or columns 182 can be formed there.
  • a width of a gap is in particular in the range between 0.2 mm and 1.0 mm and, for example, in the range between 0.4 mm and 0.6 mm.
  • the surge element 180 has one or more tear-off edges 188.
  • a separation edge 188 serves to "calm down" a flow of liquid below the surge element 180 in order to largely avoid the penetration of liquid into the subspace 178.
  • the surge element 180 has a first area 190 and a second area 192.
  • the second region 192 is bent or curved with respect to the first region 190.
  • a tear-off edge 188 is then formed between the first area 190 and the second area 192.
  • the second region 192 points towards the wall 176 and is applied to it (in particular with the gap 182), for example.
  • the storage container 130 When the hand-held steam device 10 is in operation, the storage container 130 is initially filled with liquid (in particular water) (and in particular partially filled). Liquid is in particular via the opening 80 into the storage container 130 introduced. In the case of steam operation, the cover 82 is fixed to the opening 80. Operation of the heater 138 vaporizes liquid.
  • the storage container 130 has a receiving space 194 for liquid. It also has a receiving space 196 for steam. The relative size of these receiving spaces 194, 196 is variable and depends in particular on the consumption of liquid.
  • the subspace 178 is ideally a pure steam space. There is no liquid in it, so there is only vapor that can be released.
  • the hand-held steam device 10 can be used in different positions. It is not necessary for the opening direction 152 (a height direction of the storage container 130) to be oriented parallel to the direction of gravity g. Positions of inclination to the direction of gravity g are also possible.
  • the surge element 180 largely prevents the penetration of liquid into the subspace 178.
  • the pressure accumulator device 70 has a compact design with a minimization of the height dimensions, so that the housing dimensions 12 can in turn be minimized without further compromises with regard to the liquid absorption capacity having to be made.
  • the pressure storage device 70 with the steam valve 100 arranged thereon can be handled as a unit during the manufacture of the hand-held steam device 10 and can be held as a whole on the housing insert 58.
  • the number of components required can be minimized. This in turn also facilitates manufacture.
  • the steam valve 100 or essential parts of the steam valve 100 are made of a plastic material.
